Is exercise effective for women with primary dysmenorrhoea?
|
Exercise has a number of health benefits and has been recommended as a treatment for primary dysmenorrhoea (period pain), but the evidence for its effectiveness on primary dysmenorrhoea is unclear. This review examined the available evidence supporting the use of exercise to treat primary dysmenorrhoea.
|
To evaluate the effectiveness and safety of exercise for women with primary dysmenorrhoea.
|
The current low-quality evidence suggests that exercise, performed for about 45 to 60 minutes each time, three times per week or more, regardless of intensity, may provide a clinically significant reduction in menstrual pain intensity of around 25 mm on a 100 mm VAS. All studies used exercise regularly throughout the month, with some studies asking women not to exercise during menstruation. Given the overall health benefits of exercise, and the relatively low risk of side effects reported in the general population, women may consider using exercise, either alone or in conjunction with other modalities, such as NSAIDs, to manage menstrual pain. It is unclear if the benefits of exercise persist after regular exercise has stopped or if they are similar in women over the age of 25. Further research is required, using validated outcome measures, adequate blinding and suitable comparator groups reflecting current best practice or accounting for the extra attention given during exercise.

Can NSAIDs effectively achieve a reduction in menstrual blood loss in women with heavy menstrual bleeding?
|
Heavy menstrual bleeding (HMB) is an important cause of ill health in premenopausal women. Although surgery is often used as a treatment, a range of medical therapies are also available. Non-steroidal anti-inflammatory drugs (NSAIDs) reduce prostaglandin levels, which are elevated in women with excessive menstrual bleeding and also may have a beneficial effect on dysmenorrhoea.
|
To determine the effectiveness, safety and tolerability of NSAIDs in achieving a reduction in menstrual blood loss (MBL) in women of reproductive years with HMB.
|
NSAIDs reduce HMB when compared with placebo, but are less effective than tranexamic acid, danazol or LNG IUS. However, adverse events are more severe with danazol therapy. In the limited number of small studies suitable for evaluation, there was no clear evidence of a difference in efficacy between NSAIDs and other medical treatments such as oral luteal progestogen, ethamsylate, OCP or the older progesterone-releasing intrauterine system.

Does compression therapy effectively treat post-thrombotic syndrome?
|
Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) characterised by chronic complaints such as oedema and skin changes including; venous ectasia, varicose veins, redness, eczema, hyperpigmentation, and in severe cases fibrosis of the subcutaneous adipose in the affected limb. These chronic complaints are the effects of venous outflow restriction that can cause symptoms such as heaviness, itching, pain, cramps, and paraesthesia. Twenty to fifty percent of people with DVT develop post-thrombotic complications. Several non-pharmaceutical measures are used for prevention of PTS during the acute phase of DVT. These include elevation of the legs and compression therapy. There have been limited studies regarding the effectiveness of compression therapy for prevention or treatment of PTS. As a result, clinicians and guidelines differ in their assessment of compression therapy during treatment of DVT and in the treatment of PTS. This is an update of a review first published in 2003.
|
To assess the effectiveness of compression therapy for treatment of post-thrombotic syndrome, including elastic compression stockings and mechanical devices compared with no intervention, placebo and with each other.
|
There is very low-certainty evidence regarding the use of GECS for treatment of PTS as assessed by two small studies of short duration. One study reported beneficial haemodynamic effects, while one found no benefits on PTS severity compared to control/placebo stockings. There is very limited evidence for adverse effects, patient satisfaction, QoL, and compliance rates. There is low-certainty evidence favouring use of intermittent pneumatic compression devices compared to a control device for the treatment of severity owing to different measurements used by the studies reporting on this outcome and small studies of short duration. There is moderate-certainty evidence of improved QoL but possible increased adverse effects related to compression device use owing to small studies of short duration. High-certainty evidence to support the use of compression therapy in prevention of PTS is lacking and any conclusions drawn from current evidence should be interpreted with care. Further research is needed to assess whether compression can result in long-term reduction and relief of the symptoms caused by PTS, or prevent deterioration and leg ulceration.

Does empirical antibiotic treatment approach show effectiveness and safety for acute chest syndrome compared to placebo or standard treatment?
|
The clinical presentation of acute chest syndrome is similar whether due to infectious or non-infectious causes, thus antibiotics are usually prescribed to treat all episodes. Many different pathogens, including bacteria, have been implicated as causative agents of acute chest syndrome. There is no standardized approach to antibiotic therapy and treatment is likely to vary from country to country. Thus, there is a need to identify the efficacy and safety of different antibiotic treatment approaches for people with sickle cell disease suffering from acute chest syndrome. This is an update of a Cochrane Review first published in 2007, and most recently updated in 2015.
|
To determine whether an empirical antibiotic treatment approach (used alone or in combination):1. is effective for acute chest syndrome compared to placebo or standard treatment;2. is safe for acute chest syndrome compared to placebo or standard treatment;Further objectives are to determine whether there are important variations in efficacy and safety:3. for different treatment regimens,4. by participant age, or geographical location of the clinical trials.
|
This update was unable to identify randomised controlled trials on efficacy and safety of the antibiotic treatment approaches for people with sickle cell disease suffering from acute chest syndrome. While randomised controlled trials are needed to establish the optimum antibiotic treatment for this condition, we do not envisage further trials of this intervention will be conducted, and hence the review will no longer be regularly updated.

Did the interventions effectively support the initiation or continuation of breastfeeding in women who are overweight or obese?
|
Exclusive breastfeeding is recommended for all infants until six months of age due to the many health benefits for both the mother and infant.Evidence suggests that mothers who are overweight (body mass index (BMI) 25.0 to 29.9 kg/m²) or obese (BMI ≥ 30.0 kg/m²) are less likely to initiate breastfeeding and to breastfeed for a shorter duration. Considering the rising prevalence of overweight and obesity globally and the known benefits of breastfeeding particularly in reducing the long-term risks of obesity and diabetes for infants, establishing effective ways to support and promote breastfeeding in women who are overweight or obese is paramount in achieving the goal of healthier communities.
|
To assess the effectiveness of interventions to support the initiation or continuation of breastfeeding in women who are overweight or obese.
|
There is insufficient evidence to assess the effectiveness of physical interventions, or multiple methods of support (social, educational or physical) for supporting the initiation or continuation of breastfeeding in women who are overweight or obese. We found no RCTs comparing one type of support to another type of support. All of our GRADE assessments resulted in very low-certainty evidence, with downgrading decisions based on limitations in trial design (e.g. risk of attrition bias), imprecision, inconsistency. The available trials were mostly of variable quality with small numbers of participants, confounded by poor adherence within both the intervention and control groups.Well designed, adequately powered research is needed to answer questions about the social, educational, physical support, or any combination of these interventions that could potentially help mothers who are overweight or obese to achieve optimal breastfeeding outcomes. We need trials that examine interventions designed specifically for women who are overweight or obese, delivered by people with training about how to overcome some of the challenges these women face when establishing and maintaining breastfeeding. Particular attention could be given to the assessment of antenatal interventions aimed at improving breastfeeding initiation in women with a raised BMI, and not just focusing on recruiting women who have an intention to breastfeed. Given that the majority of current trials were undertaken in the USA, further trials in a diverse range of countries and settings are required. Future trials need to give consideration to the theoretical basis of the intervention using established frameworks to enable replicability by others and to better determine the components of effective interventions.

Is splenectomy effective and safe for people with β-thalassaemia major or intermedia?
|
Thalassaemia is a genetic disorder of the haemoglobin protein in red blood cells. It has been historically classified into thalassaemia minor, intermedia and major, depending on the genetic defect and severity of the disease. The clinical presentation of β-thalassaemia varies widely from a mild asymptomatic form in thalassaemia minor, to a severe disease in thalassaemia major where individuals are dependant on life-long blood transfusions. The hallmark of thalassaemia syndromes is the production of defective red blood cells that are removed by the spleen resulting in an enlarged hyperfunctioning spleen (splenomegaly). Removal of the spleen may thus prolong red blood cell survival by reducing the amount of red blood cells removed from circulation and may ultimately result in the reduced need for blood transfusions.
|
To assess the efficacy and safety of splenectomy in people with β-thalassaemia major or intermedia.
|
The review was unable to find good quality evidence, in the form of randomised controlled studies, regarding the efficacy of splenectomy for treating thalassaemia major or intermedia. The single included study provided little information about the efficacy of splenectomy, and compared open surgery and laparoscopic methods. Further studies need to evaluate the long-term effectiveness of splenectomy and the comparative advantages of surgical methods. Due to a lack of high quality evidence from randomised controlled studies, well-conducted observational studies may be used to answer this question.

Can interim PET scan results distinguish between adults with HL with poor prognosis and those with a better prognosis, and predict survival outcomes in each group?
|
Hodgkin lymphoma (HL) is one of the most common haematological malignancies in young adults and, with cure rates of 90%, has become curable for the majority of individuals. Positron emission tomography (PET) is an imaging tool used to monitor a tumour's metabolic activity, stage and progression. Interim PET during chemotherapy has been posited as a prognostic factor in individuals with HL to distinguish between those with a poor prognosis and those with a better prognosis. This distinction is important to inform decision-making on the clinical pathway of individuals with HL.
|
To determine whether in previously untreated adults with HL receiving first-line therapy, interim PET scan results can distinguish between those with a poor prognosis and those with a better prognosis, and thereby predict survival outcomes in each group.
|
This review provides moderate-certainty evidence that interim PET scan results predict OS, and very low-certainty evidence that interim PET scan results predict progression-free survival in treated individuals with HL. This evidence is primarily based on unadjusted data. More studies are needed to test the adjusted prognostic ability of interim PET against established prognostic factors.

Does different antibiotic treatments for spontaneous bacterial peritonitis (SBP) in people with decompensated liver cirrhosis have varying benefits and harms?
|
Approximately 2.5% of all hospitalisations in people with cirrhosis are for spontaneous bacterial peritonitis (SBP). Antibiotics, in addition to supportive treatment (fluid and electrolyte balance, treatment of shock), form the mainstay treatments of SBP. Various antibiotics are available for the treatment of SBP, but there is uncertainty regarding the best antibiotic for SBP.

Can calcium supplementation given before or early in pregnancy affect pre-eclampsia and other hypertensive disorders, maternal morbidity and mortality, and fetal and neonatal outcomes?
|
The hypertensive disorders of pregnancy include pre-eclampsia, gestational hypertension, chronic hypertension, and undefined hypertension. Pre-eclampsia is considerably more prevalent in low-income than in high-income countries. One possible explanation for this discrepancy is dietary differences, particularly calcium deficiency. Calcium supplementation in the second half of pregnancy reduces the serious consequences of pre-eclampsia, but has limited effect on the overall risk of pre-eclampsia. It is important to establish whether calcium supplementation before, and in early pregnancy (before 20 weeks' gestation) has added benefit. Such evidence could count towards justification of population-level interventions to improve dietary calcium intake, including fortification of staple foods with calcium, especially in contexts where dietary calcium intake is known to be inadequate. This is an update of a review first published in 2017.
|
To determine the effect of calcium supplementation, given before or early in pregnancy and for at least the first half of pregnancy, on pre-eclampsia and other hypertensive disorders, maternal morbidity and mortality, and fetal and neonatal outcomes.
|
The single included study suggested that calcium supplementation before and early in pregnancy may reduce the risk of women experiencing the composite outcome pre-eclampsia or pregnancy loss at any gestational age, but the results are inconclusive for all other outcomes for women and babies. Therefore, current evidence neither supports nor refutes the routine use of calcium supplementation before conception and in early pregnancy.To determine the overall benefit of calcium supplementation commenced before or in early pregnancy, the effects found in the study of calcium supplementation limited to the first half of pregnancy need to be added to the known benefits of calcium supplementation in the second half of pregnancy.Further research is needed to confirm whether initiating calcium supplementation pre- or in early pregnancy is associated with a reduction in adverse pregnancy outcomes for mother and baby. Research could also address the acceptability of the intervention to women, which was not covered by this review update.

Does magnesium therapy impact the frequency of pain, length of hospital stay, and quality of life in individuals with sickle cell disease?
|
The diagnosis of Alzheimer's disease dementia and other dementias relies on clinical assessment. There is a high prevalence of cognitive disorders, including undiagnosed dementia in secondary care settings. Short cognitive tests can be helpful in identifying those who require further specialist diagnostic assessment; however, there is a lack of consensus around the optimal tools to use in clinical practice. The Mini-Cog is a short cognitive test comprising three-item recall and a clock-drawing test that is used in secondary care settings.
|
The primary objective was to determine the diagnostic accuracy of the Mini-Cog for detecting Alzheimer's disease dementia and other dementias in a secondary care setting. The secondary objectives were to investigate the heterogeneity of test accuracy in the included studies and potential sources of heterogeneity. These potential sources of heterogeneity will include the baseline prevalence of dementia in study samples, thresholds used to determine positive test results, the type of dementia (Alzheimer's disease dementia or all causes of dementia), and aspects of study design related to study quality.
|
This review identified only a limited number of diagnostic test accuracy studies using Mini-Cog in secondary care settings. Those identified were at high risk of bias related to patient selection and high concerns related to index test conduct and applicability. The evidence was indirect, as all studies evaluated Mini-Cog differently from the review question, where it was anticipated that studies would conduct Mini-Cog and independently but contemporaneously perform a reference standard assessment to diagnose dementia. The pattern of test accuracy varied across the three studies. Future research should evaluate Mini-Cog as a test in itself, rather than derived from other neuropsychological assessments. There is also a need for evaluation of the feasibility of the Mini-Cog for the diagnosis of dementia to help adequately determine its role in the clinical pathway.

Did topical CsA show effectiveness and safety in treating dry eye?
|
Topical cyclosporine A (also known as ciclosporin A) (CsA) is an anti-inflammatory that has been widely used to treat inflammatory ocular surface diseases. Two CsA eyedrops have been approved by US Food and Drug Administration for managing dry eye: Restasis (CsA 0.05%, Allergan Inc, Irvine, CA, USA), approved in 2002, and Cequa (CsA 0.09%, Sun Pharma, Cranbury, NJ, USA), approved in 2018. Numerous clinical trials have been performed to assess the effectiveness and safety of CsA for dry eye; however, there is no universal consensus with regard to its effect.
|
To assess the effectiveness and safety of topical CsA in the treatment of dry eye.
|
Despite the widespread use of topical CsA to treat dry eye, we found that evidence on the effect of CsA on ocular discomfort and ocular surface and tear film parameters such as corneal fluorescein staining, Schirmer's test, and TBUT is inconsistent and sometimes may not be different from vehicle or artificial tears for the time periods reported in the trials. There may be an increase in non-serious, treatment-related adverse effects (particularly burning) in the CsA group. Topical CsA may increase the number of conjunctival goblet cells. However, current evidence does not support that improvements in conjunctival mucus production (through increased conjunctival goblet cells) translate to improved symptoms or ocular surface and tear film parameters. All published trials were short term and did not assess whether CsA has longer-term disease-modifying effects. Well-planned, long-term, large clinical trials are needed to better assess CsA on long-term dry eye-modifying effects. A core outcome set, which ideally includes both biomarkers and patient-reported outcomes in the field of dry eye, is needed.

Did the interventions for the maintenance of surgically induced remission in Crohn's disease have a clear order of effectiveness?
|
Crohn's disease (CD) is a chronic disease of the gut. About 75% of people with CD undergo surgery at least once in their lifetime to induce remission. However, as there is no known cure for the disease, patients usually experience a recurrence even after surgery. Different interventions are routinely used in maintaining postsurgical remission. There is currently no consensus on which treatment is the most effective.

Does one treatment for hepatorenal syndrome in people with decompensated liver cirrhosis show clear benefits over others?
|
Hepatorenal syndrome is defined as renal failure in people with cirrhosis in the absence of other causes. In addition to supportive treatment such as albumin to restore fluid balance, the other potential treatments include systemic vasoconstrictor drugs (such as vasopressin analogues or noradrenaline), renal vasodilator drugs (such as dopamine), transjugular intrahepatic portosystemic shunt (TIPS), and liver support with molecular adsorbent recirculating system (MARS). There is uncertainty over the best treatment regimen for hepatorenal syndrome.
|
To compare the benefits and harms of different treatments for hepatorenal syndrome in people with decompensated liver cirrhosis.
|
Based on very low-certainty evidence, there is no evidence of benefit or harm of any of the interventions for hepatorenal syndrome with regards to the following outcomes: all-cause mortality, serious adverse events (proportion), number of serious adverse events per participant, any adverse events (proportion), liver transplantation, or other decompensation events. Low-certainty evidence suggests that albumin plus noradrenaline had fewer 'any adverse events per participant' than albumin plus terlipressin. Low- or very low-certainty evidence also found that albumin plus midodrine plus octreotide and albumin alone had lower recovery from hepatorenal syndrome compared with albumin plus terlipressin.Future randomised clinical trials should be adequately powered; employ blinding, avoid post-randomisation dropouts or planned cross-overs (or perform an intention-to-treat analysis); and report clinically important outcomes such as mortality, health-related quality of life, adverse events, and recovery from hepatorenal syndrome. Albumin plus noradrenaline and albumin plus terlipressin appear to be the interventions that should be compared in future trials.

Did public health programmes to regularly treat all children with deworming drugs have significant effects on various aspects of child health and development?

The World Health Organization (WHO) recommends treating all school children at regular intervals with deworming drugs in areas where helminth infection is common. Global advocacy organizations claim routine deworming has substantive health and societal effects beyond the removal of worms.

To summarize the effects of public health programmes to regularly treat all children with deworming drugs on child growth, haemoglobin, cognition, school attendance, school performance, physical fitness, and mortality.
|
Public health programmes to regularly treat all children with deworming drugs do not appear to improve height, haemoglobin, cognition, school performance, or mortality. We do not know if there is an effect on school attendance, since the evidence is inconsistent and at risk of bias, and there is insufficient data on physical fitness. Studies conducted in two settings over 20 years ago showed large effects on weight gain, but this is not a finding in more recent, larger studies. We would caution against selecting only the evidence from these older studies as a rationale for contemporary mass treatment programmes as this ignores the recent studies that have not shown benefit.The conclusions of the 2015 edition have not changed in this update.

Do different interventions for treating brain AVMs in adults have varying effectiveness and safety compared to each other or conservative management in RCTs?

Brain arteriovenous malformations (AVMs) are the single most common cause of intracerebral haemorrhage in young adults. Brain AVMs also cause seizure(s) and focal neurological deficits (in the absence of haemorrhage, migraine or an epileptic seizure); approximately one-fifth are incidental discoveries. Various interventions are used in an attempt to eradicate brain AVMs: neurosurgical excision, stereotactic radiosurgery, endovascular embolization, and staged combinations of these interventions.

Does respiratory muscle training (RMT) have positive effects for neuromuscular disease (NMD) in adults and children?
|
Neuromuscular diseases (NMDs) are a heterogeneous group of diseases affecting the anterior horn cell of spinal cord, neuromuscular junction, peripheral nerves and muscles. NMDs cause physical disability usually due to progressive loss of strength in limb muscles, and some NMDs also cause respiratory muscle weakness. Respiratory muscle training (RMT) might be expected to improve respiratory muscle weakness; however, the effects of RMT are still uncertain. This systematic review will synthesize the available trial evidence on the effectiveness and safety of RMT in people with NMD, to inform clinical practice.

In ALS there may not be any clinically meaningful effect of RMT on physical functioning or quality of life and it is uncertain whether it causes adverse effects.

Does changing the number of available food options or altering the positioning of foods contribute to meaningful changes in behavior?
|
Clinical management for unexplained infertility includes expectant management as well as active treatments, including ovarian stimulation (OS), intrauterine insemination (IUI), OS-IUI, and in vitro fertilisation (IVF) with or without intracytoplasmic sperm injection (ICSI).Existing systematic reviews have conducted head-to-head comparisons of these interventions using pairwise meta-analyses. As this approach allows only the comparison of two interventions at a time and is contingent on the availability of appropriate primary evaluative studies, it is difficult to identify the best intervention in terms of effectiveness and safety. Network meta-analysis compares multiple treatments simultaneously by using both direct and indirect evidence and provides a hierarchy of these treatments, which can potentially better inform clinical decision-making.

Evidence on differences between IVF/ICSI and expectant management for multiple pregnancy is insufficient, as is evidence of a difference for moderate or severe OHSS between IVF/ICSI and OS-IUI.

Did the follow-up programmes have an effect on overall survival for patients with colorectal cancer?
|
This is the fourth update of a Cochrane Review first published in 2002 and last updated in 2016.It is common clinical practice to follow patients with colorectal cancer for several years following their curative surgery or adjuvant therapy, or both. Despite this widespread practice, there is considerable controversy about how often patients should be seen, what tests should be performed, and whether these varying strategies have any significant impact on patient outcomes.

The results of our review suggest that there is no overall survival benefit for intensifying the follow-up of patients after curative surgery for colorectal cancer. Although more participants were treated with salvage surgery with curative intent in the intensive follow-up groups, this was not associated with improved survival. Harms related to intensive follow-up and salvage therapy were not well reported.

Can long-term treatment with antiarrhythmic drugs affect death, stroke, drug adverse effects, and recurrence of atrial fibrillation in people who had recovered sinus rhythm after having atrial fibrillation?
|
Atrial fibrillation is the most frequent sustained arrhythmia. Atrial fibrillation often recurs after restoration of normal sinus rhythm. Antiarrhythmic drugs have been widely used to prevent recurrence. This is an update of a review previously published in 2006, 2012 and 2015.
|
To determine the effects of long-term treatment with antiarrhythmic drugs on death, stroke, drug adverse effects and recurrence of atrial fibrillation in people who had recovered sinus rhythm after having atrial fibrillation.
|
There is high-certainty evidence of increased mortality associated with sotalol treatment, and low-certainty evidence suggesting increased mortality with quinidine, when used for maintaining sinus rhythm in people with atrial fibrillation. We found few data on mortality in people taking disopyramide, flecainide and propafenone, so it was not possible to make a reliable estimation of the mortality risk for these drugs. However, we did find moderate-certainty evidence of marked increases in proarrhythmia and adverse effects with flecainide.Overall, there is evidence showing that antiarrhythmic drugs increase adverse events, increase proarrhythmic events and some antiarrhythmics may increase mortality. Conversely, although they reduce recurrences of atrial fibrillation, there is no evidence of any benefit on other clinical outcomes, compared with placebo or no treatment.

Was the effectiveness and safety of homeopathic treatment for IBS assessed?
|
Irritable bowel syndrome (IBS) is a common, chronic disorder that leads to decreased health-related quality of life and work productivity. A previous version of this review was not able to draw firm conclusions about the effectiveness of homeopathic treatment for IBS and recommended that further high quality RCTs were conducted to explore the clinical and cost effectiveness of homeopathic treatment for IBS. Two types of homeopathic treatment were evaluated in this systematic review: 1. Clinical homeopathy where a specific remedy is prescribed for a specific condition; 2. Individualised homeopathic treatment, where a homeopathic remedy based on a person's individual symptoms is prescribed after a detailed consultation.

Did the interventions for treating recurrent stress urinary incontinence after failed minimally invasive synthetic midurethral tape surgery in women have significant effects?

Surgery is a common treatment modality for stress urinary incontinence (SUI), usually offered to women for whom conservative treatments have failed. Midurethral tapes have superseded colposuspension because cure rates are comparable and recovery time is reduced. However, some women will not be cured after midurethral tape surgery.

Can PCR-based tests on blood specimens accurately diagnose IA in immunocompromised people?
|
This is an update of the original review published in the Cochrane Database of Systematic Reviews Issue 10, 2015.Invasive aspergillosis (IA) is the most common life-threatening opportunistic invasive mould infection in immunocompromised people. Early diagnosis of IA and prompt administration of appropriate antifungal treatment are critical to the survival of people with IA. Antifungal drugs can be given as prophylaxis or empirical therapy, instigated on the basis of a diagnostic strategy (the pre-emptive approach) or for treating established disease. Consequently, there is an urgent need for research into both new diagnostic tools and drug treatment strategies. Increasingly, newer methods such as polymerase chain reaction (PCR) to detect fungal nucleic acids are being investigated.
|
To provide an overall summary of the diagnostic accuracy of PCR-based tests on blood specimens for the diagnosis of IA in immunocompromised people.
|
PCR shows moderate diagnostic accuracy when used as screening tests for IA in high-risk patient groups. Importantly the sensitivity of the test confers a high negative predictive value (NPV) such that a negative test allows the diagnosis to be excluded. Consecutive positives show good specificity in diagnosis of IA and could be used to trigger radiological and other investigations or for pre-emptive therapy in the absence of specific radiological signs when the clinical suspicion of infection is high. When a single PCR positive test is used as the diagnostic criterion for IA in a population of 100 people with a disease prevalence of 16.3% (overall mean prevalence), three people with IA would be missed (sensitivity 79.2%, 20.8% false negatives), and 17 people would be unnecessarily treated or referred for further tests (specificity of 79.6%, 21.4% false positives). If we use the two positive test requirement in a population with the same disease prevalence, it would mean that nine IA people would be missed (sensitivity 59.6%, 40.4% false negatives) and four people would be unnecessarily treated or referred for further tests (specificity of 95.1%, 4.9% false positives). Like galactomannan, PCR has good NPV for excluding disease, but the low prevalence of disease limits the ability to rule in a diagnosis. As these biomarkers detect different markers of disease, combining them is likely to prove more useful.

Does hypofractionated external beam radiation therapy have better effects compared to conventionally fractionated external beam radiation therapy for men with clinically localized prostate cancer?
|
Using hypofractionation (fewer, larger doses of daily radiation) to treat localized prostate cancer may improve convenience and resource use. For hypofractionation to be feasible, it must be at least as effective for cancer-related outcomes and have comparable toxicity and quality of life outcomes as conventionally fractionated radiation therapy.

To assess the effects of hypofractionated external beam radiation therapy compared to conventionally fractionated external beam radiation therapy for men with clinically localized prostate cancer.

These findings suggest that moderate hypofractionation (up to a fraction size of 3.4 Gy) results in similar oncologic outcomes in terms of disease-specific, metastasis-free and overall survival. There appears to be little to no increase in both acute and late toxicity.

Does the use of fetal imaging plus maternal blood glucose concentration to indicate the need for medical management reduce the risk of adverse perinatal outcomes in women with gestational diabetes?
|
Gestational diabetes mellitus (GDM) is a common medical condition that complicates pregnancy and causes adverse maternal and fetal outcomes. At present, most treatment strategies focus on normalisation of maternal blood glucose values with use of diet, lifestyle modification, exercise, oral anti-hyperglycaemics and insulin. This has been shown to reduce the incidence of adverse outcomes, such as birth trauma and macrosomia. However, this involves intensive monitoring and treatment of all women with GDM. We propose that using medical imaging to identify pregnancies displaying signs of being affected by GDM could help to target management, allowing low-risk women to be spared excessive intervention, and facilitating better resource allocation.
|
We wanted to address the following question: in women with gestational diabetes, does the use of fetal imaging plus maternal blood glucose concentration to indicate the need for medical management compared with glucose concentration alone reduce the risk of adverse perinatal outcomes?
|
This review is based on evidence from three trials involving 524 women. The trials did not report some important outcomes of interest to this review, and the majority of our secondary outcomes were also unreported. The available evidence ranged from low- to very low-certainty, with downgrading decisions based on limitations in study design, imprecision and inconsistency.There is insufficient evidence to evaluate the use of fetal biometry (in addition to maternal blood glucose concentration values) to assist in guiding the medical management of GDM, on either maternal or perinatal health outcomes, or the associated costs.More research is required, ideally larger randomised studies which report the maternal and infant short- and long-term outcomes listed in this review, as well as those outcomes relating to financial and resource implications.

Did the flexibility exercise training show benefits in adults with fibromyalgia?
|
Exercise training is commonly recommended for adults with fibromyalgia. We defined flexibility exercise training programs as those involving movements of a joint or a series of joints, through complete range of motion, thus targeting major muscle-tendon units. This review is one of a series of reviews updating the first review published in 2002.
|
To evaluate the benefits and harms of flexibility exercise training in adults with fibromyalgia.
|
When compared with aerobic training, it is uncertain whether flexibility improves outcomes such as HRQoL, pain intensity, fatigue, stiffness, and physical function, as the certainty of the evidence is very low. Flexibility exercise training may lead to little or no difference for all-cause withdrawals. It is also uncertain whether flexibility exercise training has long-term effects due to the very low certainty of the evidence. We downgraded the evidence owing to the small number of trials and participants across trials, as well as due to issues related to unclear and high risk of bias (selection, performance, and detection biases). While flexibility exercise training appears to be well tolerated (similar withdrawal rates across groups), evidence on adverse events was scarce, therefore its safety is uncertain.

Does taxane-containing adjuvant chemotherapy have effects on the treatment of women with operable early breast cancer?
|
Adjuvant chemotherapy improves survival in premenopausal and postmenopausal women with early breast cancer. Taxanes are highly active chemotherapy agents used in metastatic breast cancer. Review authors examined their role in early breast cancer. This review is an update of a Cochrane Review first published in 2007.
|
To assess the effects of taxane-containing adjuvant chemotherapy regimens for treatment of women with operable early breast cancer.
|
This review of studies supports the use of taxane-containing adjuvant chemotherapy regimens, with improvement in overall survival and disease-free survival for women with operable early breast cancer. This benefit persisted when analyses strictly compared a taxane-containing regimen versus the same regimen without a taxane or the same regimen with another drug that was substituted for the taxane. Preliminary evidence suggests that taxanes are more effective for women with lymph node-positive disease than for those with lymph node-negative disease. Considerable heterogeneity across studies probably reflects the varying efficacy of the chemotherapy backbones of the comparator regimens used in these studies. This review update reports results that are remarkably consistent with those of the original review, and it is highly unlikely that this review will be updated, as new trials are assessing treatments based on more detailed breast cancer biology.

Did chlorhexidine bathing reduce the number of hospital-acquired infections in critically ill people?
|
Hospital-acquired infection is a frequent adverse event in patient care; it can lead to longer stays in the intensive care unit (ICU), additional medical complications, permanent disability or death. Whilst all hospital-based patients are susceptible to infections, prevalence is particularly high in the ICU, where people who are critically ill have suppressed immunity and are subject to increased invasive monitoring. People who are mechanically-ventilated are at infection risk due to tracheostomy and reintubation and use of multiple central venous catheters, where lines and tubes may act as vectors for the transmission of bacteria and may increase bloodstream infections and ventilator-associated pneumonia (VAP). Chlorhexidine is a low-cost product, widely used as a disinfectant and antiseptic, which may be used to bathe people who are critically ill with the aim of killing bacteria and reducing the spread of hospital-acquired infections.
|
To assess the effects of chlorhexidine bathing on the number of hospital-acquired infections in people who are critically ill.

Due to the very low-certainty evidence available, it is not clear whether bathing with chlorhexidine reduces hospital-acquired infections, mortality, or length of stay in the ICU, or whether the use of chlorhexidine results in more skin reactions.

Did the evaluation find CZP to be effective and safe for inducing remission in CD?
|
Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract, and immune response modulation is the main treatment strategy to induce remission in active CD. Certolizumab pegol (CZP) is a tumor necrosis factor-alfa (TNF-α) inhibitor which regulates impaired immune response.
|
The primary objectives were to evaluate the efficacy and safety of CZP for the induction of remission in CD.
|
Moderate certainty evidence suggests that CZP is effective for induction of clinical remission and clinical response in participants with active CD patients. It is uncertain whether the risk of serious adverse events differs between CZP and placebo as the 95% CI includes the possibility of a small decrease or doubling of events. Future studies are needed to evaluate the long-term efficacy and safety of CZP in CD patients.

Does endometrial destruction by any means compare to hysterectomy by any means for the treatment of heavy menstrual bleeding?
|
Heavy menstrual bleeding (HMB) is an important cause of ill health in women of reproductive age, causing them physical problems, social disruption and reducing their quality of life. Medical therapy has traditionally been first-line therapy. Surgical treatment of HMB often follows failed or ineffective medical therapy. The definitive treatment is hysterectomy, but this is a major surgical procedure with significant physical and emotional complications, as well as social and economic costs. Less invasive surgical techniques, such as endometrial resection and ablation, have been developed with the purpose of improving menstrual symptoms by removing or ablating the entire thickness of the endometrium.
|
To compare the effectiveness, acceptability and safety of techniques of endometrial destruction by any means versus hysterectomy by any means for the treatment of heavy menstrual bleeding.
|
Endometrial resection and ablation offers an alternative to hysterectomy as a surgical treatment for heavy menstrual bleeding. Both procedures are effective, and satisfaction rates are high. Although hysterectomy offers permanent and immediate relief from heavy menstrual bleeding, it is associated with a longer operating time and recovery period. Hysterectomy also has higher rates of postoperative complications such as sepsis, blood transfusion and haematoma (vault and wound). The initial cost of endometrial destruction is lower than that of hysterectomy but, because retreatment is often necessary, the cost difference narrows over time.

Does immunoglobulin treatment improve outcomes for RSV-proven lower respiratory tract infections in children aged up to three years, admitted to hospital?

Tuberculosis is an infectious bacterial disease that is spread via respiratory droplets from infected individuals to susceptible contacts. To eliminate this disease from low- and medium-incidence settings, people who are most likely to be infected (contacts) must be identified. Recently, study authors have examined alternate approaches to contact tracing methods that demonstrate improved detection and prioritization of contacts. The comparative benefit of these methods has not been established.

Is sulthiame effective and tolerable as add-on therapy for people with epilepsy compared with placebo or another antiepileptic drug?

This is an updated version of the Cochrane Review previously published in the Cochrane Database of Systematic Reviews 2015, Issue 10. Epilepsy is a common neurological condition, characterised by recurrent seizures. Most people respond to conventional antiepileptic drugs, however, around 30% will continue to experience seizures, despite treatment with multiple antiepileptic drugs. Sulthiame, also known as sultiame, is a widely used antiepileptic drug in Europe and Israel. We present a summary of the evidence for the use of sulthiame as add-on therapy in epilepsy.
|

Sulthiame may lead to a cessation of seizures when used as an add-on therapy to pyridoxine in infants with West syndrome, however, we are very uncertain about the reliability of this finding. The included study was small and had a significant risk of bias, largely due to the lack of details regarding blinding and the incomplete reporting of outcomes. Both issues negatively impacted the certainty of the evidence. No conclusions can be drawn about the occurrence of adverse effects, change in quality of life, or mean reduction in seizure frequency. No evidence exists for the use of sulthiame as an add-on therapy in people with epilepsy outside West syndrome.Large, multi-centre randomised controlled trials are needed to inform clinical practice, if sulthiame is to be used as an add-on therapy for epilepsy.

Does feeding preterm or LBW infants with formula compared with maternal breast milk affect growth and developmental outcomes?

|
To determine the effect of feeding preterm or LBW infants with formula compared with maternal breast milk on growth and developmental outcomes.
|
There are no trials of formula versus maternal breast milk for feeding preterm or low birth weight infants. Such trials are unlikely to be conducted because of the difficulty of allocating an alternative form of nutrition to an infant whose mother wishes to feed with her own breast milk. Maternal breast milk remains the default choice of enteral nutrition because observational studies, and meta-analyses of trials comparing feeding with formula versus donor breast milk, suggest that feeding with breast milk has major immuno-nutritional advantages for preterm or low birth weight infants.

Does prolonged thromboprophylaxis with LMWH for at least 14 days after abdominal or pelvic surgery prevent late onset VTE compared with thromboprophylaxis administered during the in-hospital period only?
|
This an update of the review first published in 2009.Major abdominal and pelvic surgery carries a high risk of venous thromboembolism (VTE). The efficacy of thromboprophylaxis with low molecular weight heparin (LMWH) administered during the in-hospital period is well-documented, but the optimal duration of prophylaxis after surgery remains controversial. Some studies suggest that patients undergoing major abdominopelvic surgery benefit from prolongation of the prophylaxis up to 28 days after surgery.
|
To evaluate the efficacy and safety of prolonged thromboprophylaxis with LMWH for at least 14 days after abdominal or pelvic surgery compared with thromboprophylaxis administered during the in-hospital period only in preventing late onset VTE.
|
Prolonged thromboprophylaxis with LMWH significantly reduces the risk of VTE compared to thromboprophylaxis during hospital admittance only, without increasing bleeding complications or mortality after major abdominal or pelvic surgery. This finding also holds true for DVT alone, and for both proximal and symptomatic DVT. The quality of the evidence is moderate and provides moderate support for routine use of prolonged thromboprophylaxis. Given the low heterogeneity between studies and the consistent and moderate evidence of a decrease in risk for VTE, our findings suggest that additional studies may help refine the degree of risk reduction but would be unlikely to significantly influence these findings. This updated review provides additional evidence and supports the previous results reported in the 2009 review.

Does balneotherapy effectively treat chronic venous insufficiency?
|
Chronic venous insufficiency (CVI) is a progressive and common disease that affects the superficial and deep venous systems of the lower limbs. CVI is characterised by valvular incompetence, reflux, venous obstruction, or a combination of these with consequent distal venous hypertension. Clinical manifestations of CVI include oedema, pain, skin changes, ulcerations and dilated skin veins in the lower limbs. It can result in a large financial burden on health systems. There is a wide variety of treatment options or therapies for CVI, ranging from surgery and medication to compression and physiotherapy. Balneotherapy (treatments involving water) is a relatively cheap option and potentially efficient way to deliver physical therapy for people with CVI.

Does school dental screening improve oral health status?

Millions of children are hospitalised due to respiratory syncytial virus (RSV) infection every year. Treatment is supportive, and current therapies (e.g. inhaled bronchodilators, epinephrine, nebulised hypertonic saline, and corticosteroids) are ineffective or have limited effect. Respiratory syncytial virus immunoglobulin is sometimes used prophylactically to prevent hospital admission from RSV-related illness. It may be considered for the treatment of established severe RSV infection or for treatment in an immunocompromised host, although it is not licenced for this purpose. It is unclear whether immunoglobulins improve outcomes when used as a treatment for established RSV infection in infants and young children admitted to hospital. OBJECTIVES: To assess the effects of immunoglobulins for the treatment of RSV-proven lower respiratory tract infections in children aged up to three years, admitted to hospital. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), which contains the Cochrane Acute Respiratory Infections Group's Specialised Register, Ovid MEDLINE, Embase, CINAHL, and Web of Science (from inception to 6 November 2018) with no restrictions. We searched two trial registries for ongoing trials (to 30 March 2018) and checked the reference lists of reviews and included articles for additional studies.

We found insufficient evidence of a difference between immunoglobulins and placebo for any review outcomes. We assessed the evidence for the effects of immunoglobulins when used as a treatment for RSV lower respiratory tract infection in hospitalised infants and young children as of low or very low certainty due to risk of bias and imprecision. We are uncertain of the effects of immunoglobulins on these outcomes, and the true effect may be substantially different from the effects reported in this review. All trials were conducted in high-income countries, and data from populations in which the rate of death from RSV infection is higher are lacking.

The main evidence limitations were high or unclear risk of bias, including selection, performance, detection, and attrition bias; imprecision due to few participants in the studies; and indirectness from poor outcome measurement and inapplicable interventions. Future research should clearly report important outcomes, such as adverse events, and assess widely available interventions, which should include treatments aimed at prevention. These trials should ensure allocation concealment, blinding, and an adequate sample size.

Does radiotherapy (with or without chemotherapy) have long-term neurocognitive and other side effects compared to no radiotherapy or different types of radiotherapy for people with glioma?

In this review we focus on gliomas with low aggressive potential in the short term, i.e. low-grade gliomas. Most people with low-grade gliomas are treated with surgery and may receive radiotherapy thereafter. However, there is concern about the possible long-term effects of radiotherapy, especially on neurocognitive functioning.

Radiotherapy for gliomas with a good prognosis may increase the risk of neurocognitive side effects in the long term; however the magnitude of the risk is uncertain. Evidence on long-term neurocognitive side effects associated with chemoradiotherapy is also uncertain. Neurocognitive assessment should be an integral part of long-term follow-up in trials involving radiotherapy for lower-grade gliomas to improve the certainty of evidence regarding long-term neurocognitive effects. Such trials should also assess other potential long-term effects, including endocrine dysfunction, and evaluate costs and cost effectiveness.

Ovulatory disturbance is a key diagnostic feature of polycystic ovarian syndrome (PCOS), leading to infertility and correspondingly heavy disease burden. Many therapeutic strategies have been used to induce ovulation for women with PCOS who are infertile. Ultrasound-guided transvaginal ovarian needle drilling (UTND) is a novel surgical method used to induce ovulation for women with clomiphene-resistant PCOS at the outpatients clinic. Nevertheless, the quality in most of the studies seemed low, and the safety and efficacy of UTND is still uncertain.

No studies reported on the main outcomes live birth and surgical complications for the comparison UTND combined with gonadotrophins versus gonadotrophins alone. The evidence for the outcomes OHSS, pregnancy, ovulation, miscarriage, and multiple pregnancy in this comparison was of very low quality.

Does phenobarbitone have a different time to treatment failure, remission, and first seizure compared to phenytoin when used as monotherapy for seizures?
|
This is an update of a Cochrane Review first published in 2001, and last updated in 2013. This review is one in a series of Cochrane Reviews investigating pair-wise monotherapy comparisons.Epilepsy is a common neurological condition in which abnormal electrical discharges from the brain cause recurrent unprovoked seizures. It is believed that with effective drug treatment, up to 70% of individuals with active epilepsy have the potential to become seizure-free and go into long-term remission shortly after starting drug therapy with a single antiepileptic drug in monotherapy.Worldwide, particularly in the developing world, phenytoin and phenobarbitone are commonly used antiepileptic drugs, primarily because they are inexpensive. The aim of this review is to summarise data from existing trials comparing phenytoin and phenobarbitone.
|
To review the time to treatment failure, remission and first seizure with phenobarbitone compared with phenytoin when used as monotherapy in people with focal onset seizures (simple or complex focal and secondarily generalised), or generalised onset tonic-clonic seizures (with or without other generalised seizure types).

Low-certainty evidence from this review suggests that phenytoin may be a more effective drug than phenobarbitone in terms of treatment retention (treatment failures due to lack of efficacy or adverse events or both). Moderate-certainty evidence from this review also indicates no differences between the drugs in terms of time to seizure recurrence and seizure remission.However, the trials contributing to the analyses had methodological inadequacies and methodological design differences that may have impacted upon the results of this review. Therefore, we do not suggest that results of this review alone should form the basis of a treatment choice for a patient with newly onset seizures. We recommend that future trials should be designed to the highest quality possible with consideration of masking, choice of population, classification of seizure type, duration of follow-up, choice of outcomes and analysis, and presentation of results.

Do statins reduce mortality rates, exacerbation frequency, improve quality of life, or improve lung function in COPD?
|
Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable respiratory disease. COPD exacerbations are associated with worse quality of life, increased hospitalisations, and increased mortality. Currently available pharmacological interventions have variable impact on exacerbation frequency. The anti-inflammatory effects of statins may lead to decreased pulmonary and systemic inflammation, resulting in fewer exacerbations of COPD. Several observational studies have shown potential benefits of statins for patients with COPD.
|
This review aims to evaluate available evidence on benefits and harms associated with statin therapy compared with placebo as adjunct therapy for patients with COPD. Primary objectives include the following.• To determine whether statins reduce mortality rates in COPD.• To determine whether statins reduce exacerbation frequency, improve quality of life, or improve lung function in COPD.• To determine whether statins are associated with adverse effects.
|
A small number of trials providing low- or moderate-quality evidence were suitable for inclusion in this review. They showed that use of statins resulted in a reduction in CRP and IL-6, but that this did not translate into clear clinical benefit for people with COPD. Further randomised controlled trials are needed to explore this topic.

We found very low-certainty evidence that is insufficient to allow us to draw conclusions about whether there is a role for traditional school dental screening in improving dental attendance. For criteria-based screening, we found low-certainty evidence that it may improve dental attendance when compared to no screening. However, when compared to traditional screening, there is no evidence of a difference in dental attendance (very low-certainty evidence).We found low-certainty evidence to conclude that personalised or specific referral letters may improve dental attendance when compared to non-specific counterparts. We also found low-certainty evidence that screening supplemented with motivation (oral health education and offer of free treatment) may improve dental attendance in comparison to screening alone. For children requiring treatment, we found very-low certainty evidence that was inconclusive regarding whether or not a referral letter based on the 'common-sense model of self-regulation' was better than a standard referral letter.We did not find any trials addressing possible adverse effects of school dental screening or evaluating its effectiveness for improving oral health.

Does oral progestogen therapy effectively reduce menstrual blood loss in women of reproductive age with HMB?
|
Heavy menstrual bleeding (HMB) is a menstrual blood loss perceived by women as excessive that affects the health of women of reproductive age, interfering with their physical, emotional, social and material quality of life. Whilst abnormal menstrual bleeding may be associated with underlying pathology, in the present context, HMB is defined as excessive menstrual bleeding in the absence of other systemic or gynaecological disease. The first-line therapy is usually medical, avoiding possibly unnecessary surgery. Of the wide variety of medications used to reduce HMB, oral progestogens were originally the most commonly prescribed agents. This review assesses the effectiveness of two different types and regimens of oral progestogens in reducing ovulatory HMB.This is the update of a Cochrane review last updated in 2007, and originally named "Effectiveness of cyclical progestagen therapy in reducing heavy menstrual bleeding" (1998).

Low- or very low-quality evidence suggests that short-course progestogen was inferior to other medical therapy, including tranexamic acid, danazol and the Pg-IUS with respect to reduction of menstrual blood loss. Long cycle progestogen therapy (medroxyprogesterone acetate or norethisterone) was also inferior to the LNG-IUS, tranexamic acid and ormeloxifene, but may be similar to the combined vaginal ring with respect to reduction of menstrual blood loss.

Did the use of TNF-α blockers effectively treat children with Kawasaki disease?
|
Kawasaki disease (KD) is an acute inflammatory vasculitis (inflammation of the blood vessels) that mainly affects children between six months and five years of age. The vasculitis primarily impacts medium-sized blood vessels, especially in the coronary arteries. In most children, intravenous immunoglobulin (IVIG) and aspirin therapy rapidly reduce inflammatory markers, fever, and other clinical symptoms. However, approximately 15% to 20% of children receiving the initial IVIG infusion show persistent or recurrent fever and are classified as IVIG-resistant. Tumor necrosis factor-alpha (TNF-α) is an inflammatory cytokine that plays an important role in host defence against infections and in immune responses. Several studies have established that blocking TNF-α is critical for obtaining anti-inflammatory effects in children with KD, thus, there is a need to identify benefits and risks of TNF-α blockers for the treatment of KD.
|
To evaluate the efficacy and safety of using TNF-α blockers (i.e. infliximab and etanercept) to treat children with Kawasaki disease.

We found a limited number of RCTs examining the effect of TNF-α blockers for KD. In summary, low-certainty evidence indicates that TNF-α blockers have beneficial effects on treatment resistance and the adverse effect 'infusion reaction' after treatment initiation for KD when compared with no treatment or additional treatment with IVIG. Further research will add to the evidence base. Due to the small number of underpowered trials contributing to the analyses, the results presented should be treated with caution. Further large high quality trials with timing and type of TNF-α blockers used are needed to determine the effects of TNF-α blockers for KD.

Does larviciding with chemical or microbial insecticides prevent malaria transmission?
|
Larviciding refers to the regular application of chemical or microbial insecticides to water bodies or water containers to kill the aquatic immature forms of the mosquito (the larvae and pupae).
|
To summarize research evidence evaluating whether larviciding with chemical or microbial insecticides prevents malaria transmission.
|
Most controlled studies on larviciding have been performed with microbial agents. Ground larviciding for non-extensive larval habitats may have an effect on malaria transmission, and we do not know if there is an effect in large-scale aquatic habitats. We found no studies using larviciding application techniques that could cover large aquatic habitats, such as aerial spraying using aircraft.

Did the evaluation find that motivational interviewing (MI) for smoking cessation is more effective than no treatment or other forms of smoking cessation treatment?
|
Motivational Interviewing (MI) is a directive patient-centred style of counselling, designed to help people to explore and resolve ambivalence about behaviour change. It was developed as a treatment for alcohol abuse, but may help people to a make a successful attempt to stop smoking.
|
To evaluate the efficacy of MI for smoking cessation compared with no treatment, in addition to another form of smoking cessation treatment, and compared with other types of smoking cessation treatment. We also investigated whether more intensive MI is more effective than less intensive MI for smoking cessation.
|
There is insufficient evidence to show whether or not MI helps people to stop smoking compared with no intervention, as an addition to other types of behavioural support for smoking cessation, or compared with other types of behavioural support for smoking cessation. It is also unclear whether more intensive MI is more effective than less intensive MI. All estimates of treatment effect were of low certainty because of concerns about bias in the trials, imprecision and inconsistency. Consequently, future trials are likely to change these conclusions. There is almost no evidence on whether MI for smoking cessation improves mental well-being.

Does administration of prebiotics reduce the incidence of hyperbilirubinaemia among infants?
|
Hyperbilirubinaemia occurs in approximately two-thirds of all newborns during the first days of life and is frequently treated with phototherapy. Although generally seen as safe, there is rising concern regarding phototherapy and its potentially damaging effects on DNA and increased side effects particularly for preterm infants. Other methods, such as enteral feeding supplementation with prebiotics, may have an effective use in the management of hyperbilirubinaemia in neonates.
|
To determine whether administration of prebiotics reduces the incidence of hyperbilirubinaemia among term and preterm infants compared with enteral supplementation of milk with distilled water/placebo or no supplementation.
|
Current studies are unable to provide reliable evidence about the effectiveness of prebiotics on hyperbilirubinaemia. Additional large, well-designed RCTs should be undertaken in neonates that compare effects of enteral supplementation with prebiotics on neonatal hyperbilirubinaemia with supplementation of milk with any other placebo (particularly distilled water) or no supplementation.

Did interventions aiming to increase adherence to medications for smoking cessation show improved medication adherence and smoking abstinence compared to standard care?
|
Pharmacological treatments for tobacco dependence, such as nicotine replacement therapy (NRT), have been shown to be safe and effective interventions for smoking cessation. Higher levels of adherence to these medications increase the likelihood of sustained smoking cessation, but many smokers use them at a lower dose and for less time than is optimal. It is important to determine the effectiveness of interventions designed specifically to increase medication adherence. Such interventions may address motivation to use medication, such as influencing beliefs about the value of taking medications, or provide support to overcome problems with maintaining adherence.
|
To assess the effectiveness of interventions aiming to increase adherence to medications for smoking cessation on medication adherence and smoking abstinence compared with a control group typically receiving standard care.
|
In people who are stopping smoking and receiving behavioural support, there is moderate-certainty evidence that enhanced behavioural support focusing on adherence to smoking cessation medications can modestly improve adherence. There is only low-certainty evidence that this may slightly improve the likelihood of cessation in the shorter or longer-term. Interventions to increase adherence can aim to address the practicalities of taking medication, change perceptions about medication, such as reasons to take it or concerns about doing so, or both. However, there is currently insufficient evidence to confirm which approach is more effective. There is no evidence on whether such interventions are effective for people who are stopping smoking without standard behavioural support.

This is an updated version of the Cochrane Review previously published in 2017.Epilepsy is a chronic and disabling neurological disorder, affecting approximately 1% of the population. Up to 30% of people with epilepsy have seizures that are resistant to currently available antiepileptic drugs and require treatment with multiple antiepileptic drugs in combination. Felbamate is a second-generation antiepileptic drug that can be used as add-on therapy to standard antiepileptic drugs.

|
To assess the effects of self-care, dressings and footwear in preventing and healing secondary damage to the skin in persons affected by leprosy.

One study suggested that topical ketanserin is more effective than clioquinol cream or zinc paste. Topical phenytoin (two studies) may be more effective than saline dressing regarding ulcer healing. For the other dressings the results were equivocal. Canvas shoes were a little better than PVC-boots, but not significantly, and the effect of double rocker shoes compared to below-knee plasters was no different in promoting the healing of ulcers. No side effects were documented.There is a lack of high quality research in the field of ulcer prevention and treatment in leprosy. New trials should follow the current standards for design and reporting of randomised controlled trials.

Did psychological interventions aimed at preventing PTSD in individuals exposed to a traumatic event show clear efficacy compared to control conditions or other psychological interventions?
|
The prevention of long-term psychological distress following traumatic events is a major concern. Systematic reviews have suggested that individual psychological debriefing is not an effective intervention at preventing post-traumatic stress disorder (PTSD). Over the past 20 years, other forms of intervention have been developed with the aim of preventing PTSD.

While the review found some beneficial effects of multiple session early psychological interventions in the prevention of PTSD, the certainty of the evidence was low due to the high risk of bias in the included trials. The clear practice implication of this is that, at present, multiple session interventions aimed at everyone exposed to traumatic events cannot be recommended. There are a number of ongoing studies, demonstrating that this is a fast moving field of research. Future updates of this review will integrate the results of these new studies.

Is peripheral nerve block effective and safe for postoperative pain control following major knee surgery?
|
Major knee surgery is a common operative procedure to help people with end-stage knee disease or trauma to regain mobility and have improved quality of life. Poorly controlled pain immediately after surgery is still a key issue for this procedure. Peripheral nerve blocks are localized and site-specific analgesic options for major knee surgery. The increasing use of peripheral nerve blocks following major knee surgery requires the synthesis of evidence to evaluate its effectiveness and safety, when compared with systemic, local infiltration, epidural and spinal analgesia.

The current review provides evidence that the use of peripheral nerve blocks as adjunctive techniques to systemic analgesia reduced pain intensity when compared with systemic analgesia alone after major knee surgery. There were too few data to draw conclusions on other outcomes of interest. More trials are needed to demonstrate a significant difference when compared with local infiltration, epidural analgesia and spinal analgesia.

Did the Families and Schools Together (FAST) programme improve outcomes among children and their families?
|
Parents and carers have a major influence on children's learning and development from birth, through the school years, and into adulthood. Parental contributions to education include providing a secure environment in which to learn, providing intellectual stimulation, transmitting social norms and values, shaping the child's resilience through fostering literacy and problem-solving, and encouraging personal and social aspiration. Increasingly, providers of formalised education are recognising the primary role of parents, carers, and the wider family, as well as peers and the environment, in shaping children's education, health, and life experiences.

Can eHealth interventions change health behaviors in people with CKD?
|
Catatonia is a debilitating disorder of movement and volition associated with schizophrenia and some other mental illnesses. People with catatonia are more likely to require hospitalisation and highly supervised care than those without the disorder. They also have an increased risk of secondary complications such as pneumonia, malnutrition and dehydration. The mainstay of treatment has been drug therapies and electroconvulsive therapy.

No data were available for benzodiazepines compared to placebo or standard care. The lack of usable data and very low quality of data available makes it impossible to draw firm conclusions and further studies with a high-quality methodology and reporting are required in order to determine more definitively the outcomes associated with benzodiazepine use in the clinical management of catatonia in persons with schizophrenia and other SMI.

Does human albumin infusion benefit the treatment of oedema associated with nephrotic syndrome?
|
Cystic fibrosis is a genetically inherited, life-threatening condition that affects major organs. The management of cystic fibrosis involves a multi-faceted daily treatment regimen that includes airway clearance techniques, pancreatic enzymes and other medications. Previous studies have found that compliance with this intensive treatment is poor, especially among adolescents. Because of both the nature and consequences of the illness and the relentless demands of the treatment, many individuals with cystic fibrosis have a poor quality of life. Anecdotal reports suggest that singing may provide both appropriate exercise for the whole respiratory system and a means of emotional expression which may enhance quality of life. This is an update of a previously published review.

It may be used with or without diuretics such as furosemide. However, the quantitative contribution of human albumin in treating oedema is not fully understood.

Does ethical case interventions result in reduced decisional conflict or moral distress, improved patient involvement in decision-making, and a higher quality of life in adult patients?
|
Routine monitoring of gastric residual in preterm infants on gavage feeds is a common practice that is used to guide initiation and advancement of feeds. Some literature suggests that an increase in/or an altered gastric residual may be predictive of necrotising enterocolitis. Withholding monitoring of gastric residual may take away the early indicator and thus may increase the risk of necrotising enterocolitis. However, routine monitoring of gastric residual as a guide, in the absence of uniform standards, may lead to unnecessary delay in initiation and advancement of feeds and delay in reaching full enteral feeds. This in turn may increase the duration of parenteral nutrition and central venous line usage, increasing their complications. Delay in achieving full enteral feeds increases the risk of extrauterine growth restriction and neurodevelopmental impairment.
|
• To assess the efficacy and safety of routine monitoring of gastric residual versus no monitoring of gastric residual in preterm infants• To assess the efficacy and safety of routine monitoring of gastric residual based on two different criteria for interrupting feeds or decreasing feed volume in preterm infantsWe planned to undertake subgroup analysis based on gestational age (≤ 27 weeks, 28 weeks to 31 weeks, ≥ 32 weeks), birth weight (< 1000 g, 1000 g to 1499 g, ≥ 1500 g), small for gestational age versus appropriate for gestational age infants (classified using birth weight relative to the reference population), type of feed the infant is receiving (human milk or formula milk), and frequency of monitoring of gastric residual (before every feed, before every third feed, etc.) (see "Subgroup analysis and investigation of heterogeneity").
|
Review authors found insufficient evidence as to whether routine monitoring of gastric residual reduces the incidence of necrotising enterocolitis because trial results are imprecise. Low-quality evidence suggests that routine monitoring of gastric residual increases the risk of feed interruption episodes, increases the time taken to reach full enteral feeds and to regain birth weight, and increases the number of total parenteral nutrition (TPN) days.Available data are insufficient to comment on other major outcomes such as incidence of invasive infection, parenteral nutrition-associated liver disease, mortality before discharge, extrauterine growth restriction at discharge, number of CVL days, and duration of hospital stay. Further randomised controlled trials are warranted to provide more precise estimates of the effects of routine monitoring of gastric residual on important outcomes, especially necrotising enterocolitis, in preterm infants.

Did management based on knowledge of FFN testing results effectively prevent preterm birth?
|
Fetal fibronectin (FFN) is an extracellular matrix glycoprotein localized at the maternal-fetal interface of the amniotic membranes, between chorion and decidua, where it is concentrated in this area between decidua and trophoblast. In normal conditions, FFN is found at very low levels in cervicovaginal secretions. Levels greater than or equal to 50 ng/mL at or after 22 weeks have been associated with an increased risk of spontaneous preterm birth. In fact, FFN is one of the best predictors of preterm birth in all populations studied so far, and can help in selecting which women are at significant risk for preterm birth. This is an update of a review first published in 2008.
|
To assess the effectiveness of management based on knowledge of FFN testing results for preventing preterm birth.
|
The evidence from this review suggests that management based on knowledge of FFN results may reduce preterm birth before 37 weeks. However, our confidence in this result is limited as the evidence was found to be of low quality. Effects on other substantive outcomes are uncertain due to serious concerns in study design, inconsistency, and imprecision of effect estimates. No trials were identified on asymptomatic women, or multiple gestations.Future studies are needed that include specific populations (e.g. singleton gestations with symptoms of preterm labor), a study group managed with a protocol based on the FFN results, and that report not only maternal but also important perinatal outcomes. Cost-effectiveness analyses are also needed.

Can vitamin D supplementation during pregnancy safely improve maternal and neonatal outcomes?

|
To examine whether vitamin D supplementation alone or in combination with calcium or other vitamins and minerals given to women during pregnancy can safely improve maternal and neonatal outcomes.
|
We included 30 trials (7033 women) across three separate comparisons. Our GRADE assessments ranged from moderate to very low, with downgrading decisions based on limitations in study design, imprecision and indirectness.Supplementing pregnant women with vitamin D alone probably reduces the risk of pre-eclampsia, gestational diabetes, low birthweight and may reduce the risk of severe postpartum haemorrhage. It may make little or no difference in the risk of having a preterm birth < 37 weeks' gestation. Supplementing pregnant women with vitamin D and calcium probably reduces the risk of pre-eclampsia but may increase the risk of preterm births < 37 weeks (these findings warrant further research). Supplementing pregnant women with vitamin D and other nutrients may make little or no difference in the risk of preterm birth < 37 weeks' gestation or low birthweight (less than 2500 g). Additional rigorous high quality and larger randomised trials are required to evaluate the effects of vitamin D supplementation in pregnancy, particularly in relation to the risk of maternal adverse events.

When human milk is not available for feeding preterm infants, protein hydrolysate, rather than standard cow's milk formulas (with intact proteins), is often used because it is perceived as being tolerated better and less likely to lead to complications. However, protein hydrolysate formulas are more expensive than standard formulas, and concern exists that their use in practice is not supported by high-quality evidence.

Does stepwise, partial, or no dentinal caries removal have different effects compared to complete caries removal for the management of dentinal caries in primary and permanent teeth?
|
The management of dental caries has traditionally involved removal of all soft demineralised dentine before a filling is placed. However, the benefits of complete caries removal have been questioned because of concerns about the possible adverse effects of removing all soft dentine from the tooth. Three groups of studies have also challenged the doctrine of complete caries removal by sealing caries into teeth using three different techniques. The first technique removes caries in stages over two visits some months apart, allowing the dental pulp time to lay down reparative dentine (the stepwise excavation technique). The second removes part of the dentinal caries and seals the residual caries into the tooth permanently (partial caries removal) and the third technique removes no dentinal caries prior to sealing or restoring (no dentinal caries removal). This is an update of a Cochrane review first published in 2006.
|
To assess the effects of stepwise, partial or no dentinal caries removal compared with complete caries removal for the management of dentinal caries in previously unrestored primary and permanent teeth.
|
Stepwise and partial excavation reduced the incidence of pulp exposure in symptomless, vital, carious primary as well as permanent teeth. Therefore these techniques show clinical advantage over complete caries removal in the management of dentinal caries. There was no evidence of a difference in signs or symptoms of pulpal disease between stepwise excavation, and complete caries removal, and insufficient evidence to determine whether or not there was a difference in signs and symptoms of pulp disease between partial caries removal and complete caries removal. When partial caries removal was carried out there was also insufficient evidence to determine whether or not there is a difference in risk of restoration failure. The no dentinal caries removal studies investigating permanent teeth had a similar result with no difference in restoration failure. The other no dentinal caries removal study, which investigated primary teeth, showed a statistically significant difference in restoration failure favouring the intervention.Due to the short term follow-up in most of the included studies and the high risk of bias, further high quality, long term clinical trials are still required to assess the most effective intervention. However, it should be noted that in studies of this nature, complete elimination of risk of bias may not necessarily be possible. Future research should also investigate patient centred outcomes.

Does speech and language therapy effectively treat people with unexplained chronic cough?
|
Cough both protects and clears the airway. Cough has three phases: breathing in (inspiration), closure of the glottis, and a forced expiratory effort. Chronic cough has a negative, far-reaching impact on quality of life. Few effective medical treatments for individuals with unexplained (idiopathic/refractory) chronic cough (UCC) are known. For this group, current guidelines advocate the use of gabapentin. Speech and language therapy (SLT) has been considered as a non-pharmacological option for managing UCC without the risks and side effects associated with pharmacological agents, and this review considers the evidence from randomised controlled trials (RCTs) evaluating the effectiveness of SLT in this context.
|
To evaluate the effectiveness of speech and language therapy for treatment of people with unexplained (idiopathic/refractory) chronic cough.

The paucity of data in this review highlights the need for more controlled trial data examining the efficacy of SLT interventions in the management of UCC. Although a large number of studies were found in the initial search as per protocol, we could include only two studies in the review. In addition, this review highlights that endpoints vary between published studies.The improvements in HRQoL (LCQ) and reduction in 24-hour cough frequency seen with the PSALTI intervention were statistically significant but short-lived, with the between-group difference lasting up to four weeks only. Further studies are required to replicate these findings and to investigate the effects of SLT interventions over time. It is clear that SLT interventions vary between studies. Further research is needed to understand which aspects of SLT interventions are most effective in reducing cough (both objective cough frequency and subjective measures of cough) and improving HRQoL. We consider these endpoints to be clinically important. It is also important for future studies to report information on adverse events.Because of the paucity of data, we can draw no robust conclusions regarding the efficacy of SLT interventions for improving outcomes in unexplained chronic cough. Our review identifies the need for further high-quality research, with comparable endpoints to inform robust conclusions.

Does surgical intervention for IBD affect female infertility?
|
Women with inflammatory bowel disease (IBD) may require surgery, which may result in higher risk of infertility. Restorative proctocolectomy with ileal anal pouch anastomosis (IPAA) may increase infertility, but the degree to which IPAA affects infertility remains unclear, and the impact of other surgical interventions on infertility is unknown.
|
Primary objective• To determine the effects of surgical interventions for IBD on female infertility.Secondary objectives• To evaluate the impact of surgical interventions on the need for assisted reproductive technology (ART), time to pregnancy, miscarriage, stillbirth, prematurity, mode of delivery (spontaneous vaginal, instrumental vaginal, or Caesarean section), infant requirement for resuscitation and neonatal intensive care, low and very low birth weight, small for gestational age, antenatal and postpartum hemorrhage, retained placenta, postpartum depression, gestational diabetes, and gestational hypertension/preeclampsia.
|
The effect of surgical therapy for IBD on female infertility is uncertain. It is also uncertain if there are any differences in infertility among those undergoing open versus laparoscopic procedures. Previous surgery was associated with higher risk of miscarriage, use of ART, Caesarean section delivery, and giving birth to a low birth weight infant, but was not associated with risk of stillbirth, preterm delivery, or delivery of a small for gestational age infant. These findings are based on very low-quality evidence. As a result, definitive conclusions cannot be made, and future well-designed studies are needed to fully understand the impact of surgery on infertility and pregnancy outcomes.

The effects of buffered solutions and 0.9% saline solutions on preventing acute kidney injury were similar in this setting. The certainty of evidence for this finding was low, and further research could change this conclusion. Patients treated with buffered solutions showed lower chloride levels, higher levels of bicarbonate, and higher pH. The certainty of evidence for these findings was very low.

For different types of break, there may be no effect on participant-reported musculoskeletal pain, discomfort and fatigue according to low-quality evidence. Further high-quality studies are needed to determine the effectiveness of frequency, duration and type of work-break interventions among workers, if possible, with much higher sample sizes than the studies included in the current review. Furthermore, work-break interventions should be reconsidered, taking into account worker populations other than office workers, and taking into account the possibility of combining work-break intervention with other interventions such as ergonomic training or counselling, which may may possibly have an effect on musculoskeletal outcomes and work performance.

Did the interventions designed to prevent obesity in children show effectiveness?
|
Prevention of childhood obesity is an international public health priority given the significant impact of obesity on acute and chronic diseases, general health, development and well-being. The international evidence base for strategies to prevent obesity is very large and is accumulating rapidly. This is an update of a previous review.
|
To determine the effectiveness of a range of interventions that include diet or physical activity components, or both, designed to prevent obesity in children.
|
Interventions that include diet combined with physical activity interventions can reduce the risk of obesity (zBMI and BMI) in young children aged 0 to 5 years. There is weaker evidence from a single study that dietary interventions may be beneficial.However, interventions that focus only on physical activity do not appear to be effective in children of this age. In contrast, interventions that only focus on physical activity can reduce the risk of obesity (BMI) in children aged 6 to 12 years, and adolescents aged 13 to 18 years. In these age groups, there is no evidence that interventions that only focus on diet are effective, and some evidence that diet combined with physical activity interventions may be effective. Importantly, this updated review also suggests that interventions to prevent childhood obesity do not appear to result in adverse effects or health inequalities.The review will not be updated in its current form. To manage the growth in RCTs of child obesity prevention interventions, in future, this review will be split into three separate reviews based on child age.

Does early commencement of postoperative enteral nutrition lead to shorter hospital stay and fewer complications in patients undergoing lower gastrointestinal surgery?
|
This is an update of the review last published in 2011. It focuses on early postoperative enteral nutrition after lower gastrointestinal surgery. Traditional management consisted of 'nil by mouth', where patients receive fluids followed by solids after bowel function has returned. Although several trials have reported lower incidence of infectious complications and faster wound healing upon early feeding, other trials have shown no effect. The immediate advantage of energy intake (carbohydrates, protein or fat) could enhance recovery with fewer complications, and this warrants a systematic evaluation.
|
To evaluate whether early commencement of postoperative enteral nutrition (within 24 hours), oral intake and any kind of tube feeding (gastric, duodenal or jejunal), compared with traditional management (delayed nutritional supply) is associated with a shorter length of hospital stay (LoS), fewer complications, mortality and adverse events in patients undergoing lower gastrointestinal surgery (distal to the ligament of Treitz).
|
This review suggests that early enteral feeding may lead to a reduced postoperative LoS, however cautious interpretation must be taken due to substantial heterogeneity and low-quality evidence. For all other outcomes (postoperative complications, mortality, adverse events, and QoL) the findings are inconclusive, and further trials are justified to enhance the understanding of early feeding for these. In this updated review, only a few additional studies have been included, and these were small and of poor quality.To improve the evidence, future trials should address quality issues and focus on clearly defining and measuring postoperative complications to allow for better comparison between studies. However due to the introduction of fast track protocols which already include an early feeding component, future trials may be challenging. A more feasible trial may be to investigate the effect of differing postoperative energy intake regimens on relevant outcomes.

Does supplemental enteral tube feeding improve nutritional status, respiratory function, and quality of life in people with cystic fibrosis?
|
Enteral tube feeding is routinely used in many cystic fibrosis centres when oral dietary and supplement intake has failed to achieve an adequate nutritional status. The use of this method of feeding is assessed on an individual basis taking into consideration the patients age and clinical status. This is a final update of a previously published review.
|
To examine the evidence that in people with cystic fibrosis, supplemental enteral tube feeding improves nutritional status, respiratory function, and quality of life without significant adverse effects.
|
Supplemental enteral tube feeding is widely used throughout the world to improve nutritional status in people with cystic fibrosis. The methods mostly used, nasogastric or gastrostomy feeding, are expensive and may have a negative effect on self-esteem and body image. Reported use of enteral tube feeding suggests that it results in nutritional and respiratory improvement; but, efficacy has not been fully assessed by randomised controlled trials. It is acknowledged, however, that performing a randomised controlled trial would be difficult due to the ethics of withholding an intervention in a group of people whose nutritional status necessitates it.

Does mobilizing community first responders to out-of-hospital cardiac arrest events improve survival and neurological function in adults and children older than four weeks of age?
|
Mobilization of community first responders (CFRs) to the scene of an out-of-hospital cardiac arrest (OHCA) event has been proposed as a means of shortening the interval from occurrence of cardiac arrest to performance of cardiopulmonary resuscitation (CPR) and defibrillation, thereby increasing patient survival.
|
To assess the effect of mobilizing community first responders (CFRs) to out-of-hospital cardiac arrest events in adults and children older than four weeks of age, in terms of survival and neurological function.
|
Moderate-certainty evidence shows that context-specific CFR interventions result in increased rates of CPR or defibrillation performed before EMS arrival. It remains uncertain whether this can translate to significantly increased rates of overall patient survival. When possible, further high-quality RCTs that are adequately powered to measure changes in survival should be conducted.The included studies did not consider survival with good neurological function. This outcome is likely to be important to patients and should be included routinely wherever survival is measured.We identified one ongoing study and one planned trial whose results once available may change the results of this review. As this review was limited to randomized and quasi-randomized trials, we may have missed some important data from other study types.

Does exposure to the smell and taste of milk with tube feedings have a clear effect on growth and development in preterm or low birth weight infants?
|
When sufficient maternal breast milk is not available, alternative forms of enteral nutrition for preterm or low birth weight (LBW) infants are donor breast milk or artificial formula. Donor breast milk may retain some of the non-nutritive benefits of maternal breast milk for preterm or LBW infants. However, feeding with artificial formula may ensure more consistent delivery of greater amounts of nutrients. Uncertainty exists about the balance of risks and benefits of feeding formula versus donor breast milk for preterm or LBW infants.
|
To determine the effect of feeding with formula compared with donor breast milk on growth and development in preterm or low birth weight (LBW) infants.
|
In preterm and LBW infants, moderate-certainty evidence indicates that feeding with formula compared with donor breast milk, either as a supplement to maternal expressed breast milk or as a sole diet, results in higher rates of weight gain, linear growth, and head growth and a higher risk of developing necrotising enterocolitis. The trial data do not show an effect on all-cause mortality, or on long-term growth or neurodevelopment.

Can surgical intervention improve symptoms of mild to moderate knee osteoarthritis?
|
Osteoarthritis affecting the knee is common and represents a continuum of disease from early cartilage thinning to full-thickness cartilage loss, bony erosion, and deformity. Many studies do not stratify their results based on the severity of the disease at baseline or recruitment.
|
To assess the benefits and harms of surgical intervention for the management of symptomatic mild to moderate knee osteoarthritis defined as knee pain and radiographic evidence of non-end stage osteoarthritis (Kellgren-Lawrence grade 1, 2, 3 or equivalent on MRI/arthroscopy). Outcomes of interest included pain, function, radiographic progression, quality of life, short-term serious adverse events, re-operation rates and withdrawals due to adverse events.
|
The review found no placebo-or sham-controlled trials of surgery in participants with symptomatic mild to moderate knee osteoarthritis. There was low quality evidence that there may be no evidence of a difference between arthroscopic partial meniscectomy surgery and a home exercise program for the treatment of this condition. Similarly, low-quality evidence from a few small trials indicates there may not be any benefit of arthroscopic surgery over other non-surgical treatments including saline irrigation and hyaluronic acid injection, or one type of surgery over another. We are uncertain of the risk of adverse events or of progressing to total knee replacement due to very small event rates. Thus, there is uncertainty around the current evidence to support or oppose the use of surgery in mild to moderate knee osteoarthritis. As no benefit has been demonstrated from the low quality trials included in this review, it is possible that future higher quality trials for these surgical interventions may not contradict these results.

Does carbamazepine show better outcomes compared to phenytoin in treating focal onset seizures or generalised onset tonic-clonic seizures?
|
This is an update of a Cochrane Review first published in 2002 and last updated in 2017. This review is one in a series of Cochrane Reviews investigating pair-wise monotherapy comparisons.Epilepsy is a common neurological condition in which abnormal electrical discharges from the brain cause recurrent unprovoked seizures. It is believed that with effective drug treatment, up to 70% of individuals with active epilepsy have the potential to become seizure-free and go into long-term remission shortly after starting drug therapy with a single antiepileptic drug in monotherapy.Worldwide, carbamazepine and phenytoin are commonly-used broad spectrum antiepileptic drugs, suitable for most epileptic seizure types. Carbamazepine is a current first-line treatment for focal onset seizures in the USA and Europe. Phenytoin is no longer considered a first-line treatment, due to concerns over adverse events associated with its use, but the drug is still commonly used in low- to middle-income countries because of its low cost. No consistent differences in efficacy have been found between carbamazepine and phenytoin in individual trials; however, the confidence intervals generated by these trials are wide, and therefore, synthesising the data of the individual trials may show differences in efficacy.
|
To review the time to treatment failure, remission and first seizure with carbamazepine compared with phenytoin when used as monotherapy in people with focal onset seizures (simple or complex focal and secondarily generalised), or generalised onset tonic-clonic seizures (with or without other generalised seizure types).
|
Moderate-certainty evidence provided by this systematic review does not show any differences between carbamazepine and phenytoin in terms of effectiveness (retention) or efficacy (seizure recurrence and seizure remission) for individuals with focal onset or generalised onset seizures.However, some of the trials contributing to the analyses had methodological inadequacies and inconsistencies, which may have had an impact on the results of this review. We therefore do not suggest that results of this review alone should form the basis of a treatment choice for a person with newly-onset seizures. We did not find any evidence to support or refute current treatment policies. We implore that future trials be designed to the highest quality possible, with consideration of masking, choice of population, classification of seizure type, duration of follow-up, choice of outcomes and analysis, and presentation of results.

Did incentives and contingency management programs have a long-term effect on smoking cessation?
|
Drug-induced skin reactions present with a range of clinical symptoms, from mild maculopapular skin rashes to potentially fatal blistering skin rashes - such as Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) - which may result in death. Milder reactions may be troublesome and lead to low drug compliance. The pathogenesis of these drug reactions is not yet fully understood; however, there is evidence that pretreatment genetic testing may help to predict and prevent these reactions in some cases.
|
To assess the effects of prospective pharmacogenetic screening to reduce drug-associated skin reactions in a patient population.
|
Prospective screening for HLA-B*57:01 probably reduces severe hypersensitivity skin reactions to abacavir in patients positive for HIV-type 1. However, these results are only based on one study, which was at high risk of attrition and detection bias.Our primary outcomes (incidence of severe skin rashes with systemic symptoms, and long-term effects) were not assessed by the trial, and only one of the review's secondary outcomes was measured (hypersensitivity reaction); thus, we found no evidence relating to hospitalisation, death, or long-term conditions resulting from drug injury.We found no eligible evidence on genetic testing for severe drug-induced skin rash in relation to different drugs and classes of drugs. Further clinical trials based on other drugs, and in different patient populations, would be useful for advising policy changes for improving the prevention of adverse skin reactions to drug treatments.

Can exposure to the smell or taste of milk administered with tube feedings accelerate progress to full sucking feeds without adverse effects in preterm infants?
|
Financial incentives, monetary or vouchers, are widely used in an attempt to precipitate, reinforce and sustain behaviour change, including smoking cessation. They have been used in workplaces, in clinics and hospitals, and within community programmes.
|
To determine the long-term effect of incentives and contingency management programmes for smoking cessation.
|
Overall there is high-certainty evidence that incentives improve smoking cessation rates at long-term follow-up in mixed population studies. The effectiveness of incentives appears to be sustained even when the last follow-up occurs after the withdrawal of incentives. There is also moderate-certainty evidence, limited by some concerns about risks of bias, that incentive schemes conducted among pregnant smokers improve smoking cessation rates, both at the end of pregnancy and post-partum. Current and future research might explore more precisely differences between trials offering low or high cash incentives and self-incentives (deposits), within a variety of smoking populations.

Did the treatments for people with any form of morphea have a clear and definitive impact?
|
Preterm infants are often unable to co-ordinate sucking, swallowing and breathing for oral feeding because of their immaturity; in such cases, initial nutrition is provided by orogastric or nasogastric tube feeding. Feed intolerance is common and can delay attainment of full enteral feeds and sucking feeds, which prolongs the need for intravenous nutrition and hospital stay. Smell and taste play an important role in the activation of physiological pre-absorptive processes that contribute to food digestion and absorption. However, during tube feedings, milk bypasses the nasal and oral cavities, which limits exposure to the smell and taste of milk. Provision of the smell and taste of milk with tube feedings is non-invasive and inexpensive; and if it does accelerate the transition to enteral feeds, and then to sucking feeds, it would be of considerable potential benefit to infants, their families, and the healthcare system.
|
To assess whether exposure to the smell or taste (or both) of milk administered with tube feedings can accelerate progress to full sucking feeds without adverse effects in preterm infants.
|
Evidence from two trials suggests that exposure to the smell and taste of milk with tube feedings has no clear effect on time taken to reach full sucking feeds, but it may decrease length of hospitalisation. However, these results are uncertain due to the very low quality of the evidence. There is also limited evidence about the impact on other important clinical outcomes and on safety. Future research should examine the effect of exposure to the smell and taste of milk with tube feedings on clinical outcomes during hospitalisation, such as attainment of full enteral and sucking feeds, safety, feed tolerance, incidence of infection, and infant growth. Additionally, future research should be sufficiently powered to evaluate the effect of the intervention in infants of different gestational ages, on each sex separately, and on the optimal frequency and duration of exposure.

Can lifestyle changes, including weight reduction, alcohol abstinence, smoking cessation, dietary modification, exercise, and other lifestyle interventions, effectively improve psoriasis?
|
Morphea (morphoea) is an immune-mediated disease in which excess synthesis and deposition of collagen in the skin and underlying connective tissues results in hardened cutaneous areas. Morphea has different clinical features according to the subtype and stage of evolution of the disease. There is currently no consensus on optimal interventions for morphea.
|
To assess the effects of treatments for people with any form of morphea.
|
Compared to placebo plus oral prednisone, oral methotrexate plus oral prednisone may improve disease activity or damage in juvenile active morphea (linear scleroderma, generalised morphea or mixed morphea: linear and circumscribed), but there may be a slightly increased chance of experiencing at least one adverse event.When medium-dose UVA-1 (50 J/cm²), low-dose UVA-1 (20 J/cm²), and narrowband UVB were compared against each other in treating children and adults with active morphea (circumscribed morphea, linear scleroderma, generalised morphea and mixed morphea), there may be little or no difference between these treatments on global improvement of disease activity or damage. UVA-1 phototherapy may cause more mild tanning than narrowband UVB, but there may be no difference between medium- and low-dose UVA-1 phototherapy. These results are based on low-quality evidence.Limitations of data and analyses include risk of bias and imprecision (small number of participants or events and wide confidence intervals). We encourage multicentre RCTs to increase sample size and evaluate, with validated tools, different treatment responses according to the subtypes of morphea and age groups.

Psoriasis is an inflammatory skin disease that presents with itching, red, scaling plaques; its worsening has been associated with obesity, drinking, smoking, lack of sleep, and a sedentary lifestyle. Lifestyle changes may improve psoriasis.
|
To assess the effects of lifestyle changes for psoriasis, including weight reduction, alcohol abstinence, smoking cessation, dietary modification, exercise, and other lifestyle change interventions.
|
Dietary intervention may reduce the severity of psoriasis (low-quality evidence) and probably improves quality of life and reduces BMI (moderate-quality evidence) in obese people when compared with usual care, while combined dietary intervention and exercise programme probably improves psoriasis severity and BMI when compared with information only (moderate-quality evidence). None of the trials measured quality of life.We did not detect a clear difference in treatment adherence between those in the combined dietary intervention and exercise programme group and those given information only (moderate-quality evidence). Adherence may be improved through dietary intervention compared with usual care (low-quality evidence). Participants generally adhered well to the lifestyle interventions assessed in the review.No trials assessed the time to relapse. Trial limitations included unblinded participants and high dropout rate.Future trials should reduce dropouts and include comprehensive outcome measures; they should examine whether dietary intervention with or without an exercise programme is effective in non-obese people with psoriasis, whether an additional exercise programme is more effective than dietary intervention alone, whether the time to relapse prolongs in people who receive dietary intervention with or without exercise programme, and whether smoking cessation and alcohol abstinence are effective in treating psoriasis.

The liver is affected by two of the most common groups of malignant tumours: primary liver tumours and liver metastases from colorectal carcinoma. Liver metastases are significantly more common than primary liver cancer and long-term survival rates reported for patients after radical surgical treatment is approximately 50%. However, R0 resection (resection for cure) is not feasible in the majority of patients. Cryotherapy is performed with the use of an image-guided cryoprobe which delivers liquid nitrogen or argon gas to the tumour tissue. The subsequent process of freezing is associated with formation of ice crystals, which directly damage exposed tissue, including cancer cells.

Can supplementary inositol reduce adverse neonatal outcomes in preterm infants with or without respiratory distress syndrome?
|
Inositol is an essential nutrient required by human cells in culture for growth and survival. Inositol promotes maturation of several components of surfactant and may play a critical role in fetal and early neonatal life. A drop in inositol levels in infants with respiratory distress syndrome (RDS) can be a sign that their illness will be severe.
|
To assess the effectiveness and safety of supplementary inositol in preterm infants with or without respiratory distress syndrome (RDS) in reducing adverse neonatal outcomes including: death (neonatal and infant deaths), bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intraventricular haemorrhage (IVH), periventricular leukomalacia (PVL), necrotizing enterocolitis (NEC) and sepsis.
|
Based on the evidence from randomised controlled trials to date, inositol supplementation does not result in important reductions in the rates of infant deaths, ROP stage 3 or higher, type 1 ROP, IVH grades 3 or 4, BPD, NEC, or sepsis. These conclusions are based mainly on two recent randomised controlled trials in neonates less than 30 weeks' postmenstrual age (N = 760), the most vulnerable population. Currently inositol supplementation should not be routinely instituted as part of the nutritional management of preterm infants with or without RDS. It is important that infants who have been enrolled in the trials included in this review are followed to assess any effects of inositol supplementation on long-term outcomes in childhood. We do not recommend any additional trials in neonates.

Intrahepatic cholestasis of pregnancy is a pregnancy-specific liver disorder, possibly associated with an increased risk of severe fetal adverse events. Total serum bile acids (TSBA) concentration, alone or in combination with serum aminotransferases, have been the most often used biomarkers for the diagnosis of intrahepatic cholestasis of pregnancy in clinical practice. Serum bile acid profile, composed of primary or secondary, conjugated or non-conjugated bile acids, may provide more specific disease information.

|
The overall high risk of bias, the existing concern regarding applicability of the results in clinical practice, and the great heterogeneity of the results in the included studies prevents us from making recommendations and reaching definitive conclusions at the present time. Thus, we do not find any compelling evidence to recommend or refute the routine use of any of these tests in clinical practice. So far, the diagnostic accuracy of TSBA for intrahepatic cholestasis of pregnancy might have been overestimated. There were too few studies to permit a precise estimate of the accuracy of serum bile acid profile components. Further primary clinical research is mandatory. We need both further phase II and phase III diagnostic studies.

Did the trials establish the efficacy and safety of re-feeding compared to discarding gastric residuals in preterm infants?
|
Routine monitoring of gastric residuals in preterm infants on gavage feeds is a common practice in many neonatal intensive care units and is used to guide the initiation and advancement of feeds. No guidelines or consensus is available on whether to re-feed or discard the aspirated gastric residuals. Although re-feeding gastric residuals may replace partially digested milk, gastrointestinal enzymes, hormones, and trophic substances that aid in digestion and promote gastrointestinal motility and maturation, re-feeding abnormal residuals may result in emesis, necrotising enterocolitis, or sepsis.
|
To assess the efficacy and safety of re-feeding compared to discarding gastric residuals in preterm infants. The allocation should have been started in the first week of life and should have been continued at least until the baby reached full enteral feeds. The investigator could have chosen to discard the gastric residual in the re-feeding group, if the gastric residual quality was not satisfactory. However, the criteria for discarding gastric residual should have been predefined.To conduct subgroup analysis based on gestational age (≤ 27 weeks, 28 weeks to 31 weeks, ≥ 32 weeks), birth weight (< 1000 g, 1000 g to 1499 g, ≥ 1500 g), type of milk (human milk or formula milk), quality of the gastric residual (fresh milk, curded milk, or bile-stained gastric residual), volume of gastric residual replaced (total volume, 50% of the volume, volume of the next feed, or prespecified volume, irrespective of the volume of the aspirate, e.g. 2 mL, 3 mL), and whether the volume of gastric residual that is re-fed is included in or excluded from the volume of the next feed (see "Subgroup analysis and investigation of heterogeneity").
|
We found only limited data from one small unblinded trial on the efficacy and safety of re-feeding gastric residuals in preterm infants. The quality of evidence was low to very low. Hence, available evidence is insufficient to support or refute re-feeding of gastric residuals in preterm infants. A large, randomised controlled trial is needed to provide data of sufficient quality and precision to inform policy and practice.

Does acupuncture impact ovulation induction via increased beta-endorphin production effecting GnRH secretion?

Pay-for-Performance (P4P) is a payment model that rewards health care providers for meeting pre-defined targets for quality indicators or efficacy parameters to increase the quality or efficacy of care.
|
Our objective was to assess the impact of P4P for in-hospital delivered health care on the quality of care, resource use and equity. Our objective was not only to answer the question whether P4P works in general (simple perspective) but to provide a comprehensive and detailed overview of P4P with a focus on analyzing the intervention components, the context factors and their interrelation (more complex perspective).
|
It is uncertain whether P4P, compared to capitation-based payments without P4P for hospitals, has an impact on patient outcomes, quality of care, equity or resource use as the certainty of the evidence was very low (or we found no studies on the outcome) for all P4P programs. The effects on patient outcomes of P4P in hospitals were at most small, regardless of design factors and context/setting. It seems that with additional payments only small short-term but non-sustainable effects can be achieved. Non-payments seem to be slightly more effective than bonuses and payments for quality attainment seem to be slightly more effective than payments for quality improvement.

Did the alternative primaquine regimens show better efficacy and safety for radical cure of P vivax malaria compared to the standard or high-standard 14 days of primaquine?
|
Malaria caused by Plasmodium vivax requires treatment of the blood-stage infection and treatment of the hypnozoites that develop in the liver. This is a challenge to effective case management of P vivax malaria, as well as being a more general substantial impediment to malaria control. The World Health Organization (WHO) recommends a 14-day drug course with primaquine, an 8-aminoquinoline, at 0.25 mg/kg/day in most of the world (standard course), or 0.5 mg/kg/day in East Asia and Oceania (high-standard course). This long treatment course can be difficult to complete, and primaquine can cause dangerous haemolysis in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency, meaning that physicians may be reluctant to prescribe in areas where G6PD testing is not available. This Cochrane Review evaluated whether more patient-friendly alternative regimens are as efficacious as the standard regimen for radical cure ofP vivax malaria.

Although limited data were available, the analysis did not detect a difference in recurrence between the 7-day regimen and the standard 14-day regimen of 0.5 mg/kg/day primaquine, and no serious adverse events were reported in G6PD-normal participants taking 0.5 mg/kg/day of primaquine. This shorter regimen may be useful in G6PD-normal patients if there are treatment adherence concerns. Further large high-quality RCTs are needed, such as the IMPROV trial, with more standardised comparison regimens and longer follow-up to help resolve uncertainties.

Did the exercise intervention show benefits in preventing fragility fractures among adults with a history of vertebral fractures?
|
Vertebral fractures are associated with increased morbidity (e.g. pain, reduced quality of life) and mortality. Therapeutic exercise is a non-pharmacological conservative treatment that is often recommended for patients with vertebral fractures to reduce pain and restore functional movement. This is an update of a Cochrane Review first published in 2013.
|
To assess the effects (benefits and harms) of exercise intervention of four weeks or greater (alone or as part of a physical therapy intervention) versus non-exercise/non-active physical therapy intervention, no intervention or placebo among adults with a history of vertebral fractures on incident fragility fractures of the hip, vertebra or other sites. Our secondary objectives were to evaluate the effects of exercise on the following outcomes: falls, pain, physical performance, health-related quality of life (disease-specific and generic), and adverse events.
|
In conclusion, we do not have sufficient evidence to determine the effects of exercise on incident fractures, falls or adverse events. Our updated review found moderate-quality evidence that exercise probably improves physical performance, specifically Timed Up and Go test, in individuals with vertebral fracture (downgraded due to study limitations). However, a one-second improvement in Timed Up and Go is not a clinically important improvement. Although individual trials did report benefits for some pain and disease-specific quality of life outcomes, the findings do not represent clinically meaningful improvements and should be interpreted with caution given the very low-quality evidence due to inconsistent findings, study limitations and imprecise estimates. The small number of trials and variability across trials limited our ability to pool outcomes or make conclusions. Evidence regarding the effects of exercise after vertebral fracture in men is scarce. A high-quality randomized trial is needed to inform safety and effectiveness of exercise to lower incidence of fracture and falls and to improve patient-centered outcomes (pain, function) for individuals with vertebral fractures (minimal sample size required is approximately 2500 untreated participants or 4400 participants if taking anti-osteoporosis therapy).

Did regular inhaled corticosteroids show effectiveness in improving outcomes for children and adults with cystic fibrosis?
|
The reduction of lung inflammation is one of the goals of cystic fibrosis therapy. Inhaled corticosteroids are often used in this respect to treat children and adults with cystic fibrosis. The rationale for this is their potential to reduce lung damage arising from inflammation, as well as their effect on symptomatic wheezing. It is important to establish the current level of evidence for the risks and benefits of inhaled corticosteroids, especially in the light of their known adverse effects on growth. This is an update of a previously published review; however, due to the lack of research in this area, we do not envisage undertaking any further updates.
|

Evidence from these trials is of low to very low quality and insufficient to establish whether inhaled corticosteroids are beneficial in cystic fibrosis, but withdrawal in those already taking them has been shown to be safe. There is some evidence they may cause harm in terms of growth. It has not been established whether long-term use is beneficial in reducing lung inflammation, which should improve survival, but it is unlikely this will be proven conclusively in a randomised controlled trial.

Do pharmacological interventions for the prevention or treatment of upper gastrointestinal bleeding in neonates compare with placebo or no treatment, supportive care, or each other?
|
Upper gastrointestinal bleeding is typically a mild, self-limiting condition that can affect both preterm and term neonates, although it can be severe particularly when associated with co-morbidities. Pharmacological interventions with a proton pump inhibitor (PPI), H2 receptor antagonist (H2RA), antacid, bismuth and sucralfate may have effects on both the prevention and treatment of upper gastrointestinal bleeding in infants.
|
To assess how different pharmacological interventions (PPIs, H2RAs, antacids, sucralfate or bismuth salts) administered to preterm and term neonates for the prevention or treatment of upper gastrointestinal bleeding to reduce morbidity and mortality compare with placebo or no treatment, supportive care, or each other.
|
There is moderate-quality evidence that use of an H2 receptor antagonist reduces the risk of gastrointestinal bleeding in newborn infants at high risk of gastrointestinal bleeding. There is low-quality evidence that use of an inhibitor of gastric acid (H2 receptor antagonist or proton pump inhibitor) reduces the duration of upper gastrointestinal bleeding and the incidence of continued gastric bleeding in newborn infants with gastrointestinal bleeding. However, there is no evidence that use of an inhibitor of gastric acid in newborn infants affects mortality or the need for blood transfusion. As no study reported the incidence of necrotising enterocolitis, ventilator- or hospital-associated pneumonia, sepsis, or long-term outcome, the safety of inhibitors of gastric acid secretion is unclear.

Did the evaluation find evidence supporting the efficacy of psychological therapies for the prevention of migraine in adults?
|
Migraine is a common neurological problem associated with the highest burden amongst neurological conditions in terms of years lived with disability. Medications can be used as prophylaxis or rescue medicines, but are costly and not always effective. A range of psychological interventions have been developed to manage migraine.
|
The objective was to evaluate the efficacy and adverse events of psychological therapies for the prevention of migraine in adults.
|
This review identified 21 studies of psychological interventions for the management of migraine. We did not find evidence that psychological interventions affected migraine frequency, a result based on four studies of primarily brief treatments. Those who received psychological interventions were twice as likely to be classified as responders in the short term, but this was based on very low-quality evidence and there was no evidence of an effect of psychological intervention compared to control at follow-up. There was no evidence of an effect of psychological interventions on medication usage, mood, migraine-related disability or quality of life. There was no evidence of an effect of psychological interventions on migraine frequency in the short-term or long-term. In terms of adverse events, we were unable to draw conclusions as there was insufficient evidence. High and unclear risk of bias in study design and reporting, small numbers of participants, performance and detection bias meant that we rated all evidence as very low quality. Therefore, we conclude that there is an absence of high-quality evidence to determine whether psychological interventions are effective in managing migraine in adults and we are uncertain whether there is any difference between psychological therapies and controls.

Is there evidence to support the effect of banked donor preterm milk compared to banked term milk on growth and developmental outcomes in very low birth weight infants?

Melanoma is one of the most aggressive forms of skin cancer, with the potential to metastasise to other parts of the body via the lymphatic system and the bloodstream. Melanoma accounts for a small percentage of skin cancer cases but is responsible for the majority of skin cancer deaths. Various imaging tests can be used with the aim of detecting metastatic spread of disease following a primary diagnosis of melanoma (primary staging) or on clinical suspicion of disease recurrence (re-staging). Accurate staging is crucial to ensuring that patients are directed to the most appropriate and effective treatment at different points on the clinical pathway. Establishing the comparative accuracy of ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET)-CT imaging for detection of nodal or distant metastases, or both, is critical to understanding if, how, and where on the pathway these tests might be used.
|
Primary objectivesWe estimated accuracy separately according to the point in the clinical pathway at which imaging tests were used. Our objectives were:• to determine the diagnostic accuracy of ultrasound or PET-CT for detection of nodal metastases before sentinel lymph node biopsy in adults with confirmed cutaneous invasive melanoma; and• to determine the diagnostic accuracy of ultrasound, CT, MRI, or PET-CT for whole body imaging in adults with cutaneous invasive melanoma:○ for detection of any metastasis in adults with a primary diagnosis of melanoma (i.e. primary staging at presentation); and○ for detection of any metastasis in adults undergoing staging of recurrence of melanoma (i.e. re-staging prompted by findings on routine follow-up).We undertook separate analyses according to whether accuracy data were reported per patient or per lesion.Secondary objectivesWe sought to determine the diagnostic accuracy of ultrasound, CT, MRI, or PET-CT for whole body imaging (detection of any metastasis) in mixed or not clearly described populations of adults with cutaneous invasive melanoma.For study participants undergoing primary staging or re-staging (for possible recurrence), and for mixed or unclear populations, our objectives were:• to determine the diagnostic accuracy of ultrasound, CT, MRI, or PET-CT for detection of nodal metastases;• to determine the diagnostic accuracy of ultrasound, CT, MRI, or PET-CT for detection of distant metastases; and• to determine the diagnostic accuracy of ultrasound, CT, MRI, or PET-CT for detection of distant metastases according to metastatic site.
|
Review authors found a disappointing lack of evidence on the accuracy of imaging in people with a diagnosis of melanoma at different points on the clinical pathway. Studies were small and often reported data according to the number of lesions rather than the number of study participants. Imaging with ultrasound combined with FNAC before SLNB may identify around one-fifth of those with nodal disease, but confidence intervals are wide and further work is needed to establish cost-effectiveness. Much of the evidence for whole body imaging for primary staging or re-staging of disease is focused on PET-CT, and comparative data with CT or MRI are lacking. Future studies should go beyond diagnostic accuracy and consider the effects of different imaging tests on disease management. The increasing availability of adjuvant therapies for people with melanoma at high risk of disease spread at presentation will have a considerable impact on imaging services, yet evidence for the relative diagnostic accuracy of available tests is limited.

Does the use of dilute formula in preterm or low birth weight formula-fed infants lead to a significant reduction in the time taken for preterm infants to attain an adequate energy intake?
|
In epidemics of highly infectious diseases, such as Ebola Virus Disease (EVD) or Severe Acute Respiratory Syndrome (SARS), healthcare workers (HCW) are at much greater risk of infection than the general population, due to their contact with patients' contaminated body fluids. Contact precautions by means of personal protective equipment (PPE) can reduce the risk. It is unclear which type of PPE protects best, what is the best way to remove PPE, and how to make sure HCW use PPE as instructed.
|
To evaluate which type of full body PPE and which method of donning or doffing PPE have the least risk of self-contamination or infection for HCW, and which training methods increase compliance with PPE protocols.
|
We found very low quality evidence that more breathable types of PPE may not lead to more contamination, but may have greater user satisfaction. Alterations to PPE, such as tabs to grab may decrease contamination. Double gloving, following CDC doffing guidance, and spoken instructions during doffing may reduce contamination and increase compliance. Face-to-face training in PPE use may reduce errors more than video or folder based training. Because data come from single small studies with high risk of bias, we are uncertain about the estimates of effects.We still need randomised controlled trials to find out which training works best in the long term. We need better simulation studies conducted with several dozen participants to find out which PPE protects best, and what is the safest way to remove PPE. Consensus on the best way to conduct simulation of exposure and assessment of outcome is urgently needed. HCW exposed to highly infectious diseases should have their use of PPE registered and should be prospectively followed for their risk of infection in the field.

Does folic acid fortification of wheat and maize flour provide health benefits and safety for the overall population?
|
Folate is a B-vitamin required for DNA synthesis, methylation, and cellular division. Wheat and maize (corn) flour are staple crops consumed widely throughout the world and have been fortified with folic acid in over 80 countries to prevent neural tube defects. Folic acid fortification may be an effective strategy to improve folate status and other health outcomes in the overall population.
|
To evaluate the health benefits and safety of folic acid fortification of wheat and maize flour (i.e. alone or in combination with other micronutrients) on folate status and health outcomes in the overall population, compared to wheat or maize flour without folic acid (or no intervention).
|
Fortification of wheat flour with folic acid may reduce the risk of neural tube defects; however, this outcome was only reported in one non-RCT. Fortification of wheat or maize flour with folic acid (i.e. alone or with other micronutrients) may increase erythrocyte and serum/plasma folate concentrations. Evidence is limited for the effects of folic acid-fortified wheat or maize flour on haemoglobin levels or anaemia. The effects of folic acid fortification of wheat or maize flour on other primary outcomes assessed in this review is not known. No studies reported on the occurrence of adverse effects. Limitations of this review were the small number of studies and participants, limitations in study design, and low-certainty of evidence due to how included studies were designed and reported.

Can thyroxine be a useful treatment for improving pregnancy outcomes in subfertile women with specific types of thyroid disease?
|
Intimate partner abuse (including coercive control, physical, sexual, economic, emotional and economic abuse) is common worldwide. Advocacy may help women who are in, or have left, an abusive intimate relationship, to stop or reduce repeat victimisation and overcome consequences of the abuse. Advocacy primarily involves education, safety planning support and increasing access to different services. It may be stand-alone or part of other services and interventions, and may be provided within healthcare, criminal justice, social, government or specialist domestic violence services. We focus on the abuse of women, as interventions for abused men require different considerations.
|
To assess advocacy interventions for intimate partner abuse in women, in terms of which interventions work for whom, why and in what circumstances.
|
Results confirm the core ingredients of advocacy and suggest its use rests on sound theoretical underpinnings. We determined the elements of a good therapeutic alliance and how it might be improved, with a need for particular considerations of the factors affecting marginalised women. Women's goals from advocacy should be considered in the contexts of their personal lives. Women's safety was not necessarily at greatest risk from staying with the abuser. Potentially, if undertaken for long enough, advocacy should benefit an abused woman in terms of at least one outcome providing the goals are matched to each woman's needs. Some outcomes may take months to be determined. Where abuse is severe, some interventions may increase abuse. Advocates have a challenging role and must be supported emotionally, through provision of resources and through professional training, by organisations and peers.Future research should consider the different principles identified in this review, and study outcomes should be considered in relation to the mechanisms and contexts elucidated. More longitudinal evidence is needed. Single-subject research designs may help determine exactly when effect no longer increases, to determine the duration of longitudinal work, which will likely differ for vulnerable and marginalised women. Further work is needed to ascertain how to tailor advocacy interventions to cultural variations and rural and resource-poor settings. The methods used in the included studies may, in some cases, limit the applicability and completeness of the data reported. Economic analyses are required to ascertain if resources devoted to advocacy interventions are cost-effective in healthcare and community settings.

Does the use of plasma volume expanders for paracentesis in people with cirrhosis and large ascites show clear benefits and harms?
|
Plasma volume expanders are used in connection to paracentesis in people with cirrhosis to prevent reduction of effective plasma volume, which may trigger deleterious effect on haemodynamic balance, and increase morbidity and mortality. Albumin is considered the standard product against which no plasma expansion or other plasma expanders, e.g. other colloids (polygeline , dextrans, hydroxyethyl starch solutions, fresh frozen plasma), intravenous infusion of ascitic fluid, crystalloids, or mannitol have been compared. However, the benefits and harms of these plasma expanders are not fully clear.
|
To assess the benefits and harms of any plasma volume expanders such as albumin, other colloids (polygeline, dextrans, hydroxyethyl starch solutions, fresh frozen plasma), intravenous infusion of ascitic fluid, crystalloids, or mannitol versus no plasma volume expander or versus another plasma volume expander for paracentesis in people with cirrhosis and large ascites.
|
Our systematic review and meta-analysis did not find any benefits or harms of plasma expanders versus no plasma expander or of one plasma expander such as polygeline, dextrans, hydroxyethyl starch, intravenous infusion of ascitic fluid, crystalloids, or mannitol versus albumin on primary or secondary outcomes. The data originated from few, small, mostly short-term trials at high risks of systematic errors (bias) and high risks of random errors (play of chance). GRADE assessments concluded that the evidence was of very low certainty. Therefore, we can neither demonstrate or discard any benefit of plasma expansion versus no plasma expansion, and differences between one plasma expander versus another plasma expander.Larger trials at low risks of bias are needed to assess the role of plasma expanders in connection with paracentesis. Such trials should be conducted according to the SPIRIT guidelines and reported according to the CONSORT guidelines.
