Background: Spina bifida is a fetal neural tube defect (NTD), which may be diagnosed in utero and is compatible with life postnatally, albeit often with significant disability and morbidity. Although postnatal repair is possible, with increasing in utero diagnosis with ultrasound, the condition has been treated during pregnancy (prenatal repair) with the aim of decreased morbidity for the child. The procedure that is performed during pregnancy does have potential morbidities for the mother, as it involves maternal surgery to access the fetus.
Objectives: To compare the effects of prenatal versus postnatal repair and different types of repair of spina bifida on perinatal mortality and morbidity, longer term infant outcomes and maternal morbidity.
Selection criteria: All published, unpublished, and ongoing randomised controlled trials comparing prenatal and postnatal repair of meningomyelocele for fetuses with spina bifida and different types of prenatal repair.
Background: Ventilator-associated pneumonia (VAP) is common in intensive care units (ICUs). Some evidence indicates that probiotics may reduce the incidence of VAP. Several additional published studies have demonstrated that probiotics are safe and efficacious in preventing VAP in ICUs. We aimed to systematically summarise the results of all available data to generate the best evidence for the prevention of VAP.
Objectives: To evaluate the effectiveness and safety of probiotics for preventing VAP.
Selection criteria: Randomised controlled trials (RCTs) comparing probiotics with placebo or another control (excluding RCTs that use probiotics in both study groups) to prevent VAP.
Background: School tobacco policies (STPs) might prove to be a promising strategy to prevent smoking initiation among adolescents, as there is evidence that the school environment can influence young people to smoke. STPs are cheap, relatively easy to implement and have a wide reach, but it is not clear whether this approach is effective in preventing smoking uptake.
Objectives: To assess the effectiveness of policies aiming to prevent smoking initiation among students by regulating smoking in schools.
Selection criteria: We included cluster-randomised controlled trials (c-RCTs) in which primary and secondary schools were randomised to receive different levels of smoking policy or no intervention. Non-randomised controlled trials, interrupted time series and controlled before-after studies would also have been eligible. Cross-sectional studies were not formally included but we describe their findings and use them to generate hypotheses to inform future research.
Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to reduce inflammatory pain and swelling in inflammatory bowel disease (IBD) patients with rheumatological manifestations. While these drugs effectively reduce musculoskeletal pain and stiffness, long-term use is limited by gastrointestinal (GI) adverse effects (AEs) and disease exacerbation. As an alternative to NSAIDs, selective cyclooxygenase 2 (COX-2) inhibitors were developed to improve GI safety and tolerability. COX-2 inhibitors include drugs such as celecoxib, rofecoxib, valdecoxib, etoricoxib, and lumiracoxib. Rofecoxib and valdecoxib have been withdrawn from the market worldwide due to safety concerns (most importantly for cardiovascular adverse events) and lumiracoxib has been withdrawn in many countries due to liver toxicity. However, celecoxib and etoricoxib continue to be available for use in many countries. Several studies have examined whether COX-2 inhibitors can be safely used for the treatment of rheumatological manifestations of IBD with inconsistent results. Some investigators report acceptable safety profiles associated with these drugs while others found that COX-2 inhibitors are associated with high rates of disease exacerbation.
Objectives: The objective of this systematic review was to evaluate the tolerability and safety of COX-2 inhibitors used for the treatment of rheumatological manifestations of IBD.
Selection criteria: Randomized controlled trials (RCTs) that compared COX-2 inhibitors to placebo were considered for inclusion. Participants were adult patients with IBD presenting with rheumatological manifestations of at least two weeks duration.
Background: Sleep bruxism is an oral activity characterized by involuntary teeth grinding or clenching during sleep. Several forms of treatment have been proposed for this disorder, including behavioural, dental and pharmacological strategies.
Objectives: To evaluate the effectiveness and safety of pharmacological therapy for the treatment of sleep bruxism compared with other drugs, no treatment or placebo.
Selection criteria: We selected randomized controlled trials (RCTs) or quasi-RCTs that compared drugs with other drugs, no treatment or placebo in people with sleep bruxism.
Background: Astragalus (Radix Astragali, huang qi) is the dried root of Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao or Astragalus membranaceus (Fisch.) Bge. (Family Leguminosae). It is one of the most widely used herbs in traditional Chinese medicine for treating kidney diseases. Evidence is needed to help clinicians and patients make judgments about its use for managing chronic kidney disease (CKD).
Objectives: This review evaluated the benefits and potential harms of Astragalus for the treatment of people with CKD.
Selection criteria: Randomised controlled trials (RCTs) and quasi-RCTs comparing Astragalus, used alone as a crude herb or an extract, with placebo, no treatment, or conventional interventions were eligible for inclusion.
Background: Because immunological aberrations might be the cause of miscarriage in some women, several immunotherapies have been used to treat women with otherwise unexplained recurrent pregnancy loss.
Objectives: The objective of this review was to assess the effects of any immunotherapy, including paternal leukocyte immunization and intravenous immunoglobulin on the live birth rate in women with previous unexplained recurrent miscarriages.
Selection criteria: Randomized trials of immunotherapies used to treat women with three or more prior miscarriages and no more than one live birth after, in whom all recognized non-immunologic causes of recurrent miscarriage had been ruled out and no simultaneous treatment was given.
Background: Fibroids are common benign tumours arising in the uterus. Myomectomy is the surgical treatment of choice for women with symptomatic fibroids who prefer or want uterine conservation. Myomectomy can be performed by conventional laparotomy, by mini-laparotomy or by minimal access techniques such as hysteroscopy and laparoscopy.
Objectives: To determine the benefits and harms of laparoscopic or hysteroscopic myomectomy compared with open myomectomy.
Selection criteria: All published and unpublished randomised controlled trials comparing myomectomy via laparotomy, mini-laparotomy or laparoscopically assisted mini-laparotomy versus laparoscopy or hysteroscopy in premenopausal women with uterine fibroids diagnosed by clinical and ultrasound examination were included in the meta-analysis.
Background: Asthma is the most common respiratory disorder complicating pregnancy, and is associated with a range of adverse maternal and perinatal outcomes. There is strong evidence however, that the adequate control of asthma can improve health outcomes for mothers and their babies. Despite known risks of poorly controlled asthma during pregnancy, a large proportion of women have sub-optimal asthma control, due to concerns surrounding risks of pharmacological agents, and uncertainties regarding the effectiveness and safety of different management strategies.
Objectives: To assess the effects of interventions (pharmacologic and non-pharmacologic) for managing women's asthma in pregnancy on maternal and fetal/infant outcomes.
Selection criteria: Randomised and quasi-randomised controlled trials comparing any intervention used to manage asthma in pregnancy, with placebo, no intervention, or an alternative intervention. We included pharmacological and non-pharmacological interventions (including combined interventions). Cluster-randomised trials were eligible for inclusion (but none were identified). Cross-over trials were not eligible for inclusion.We included multi-armed trials along with two-armed trials. We also included studies published as abstracts only.
Background: Acupuncture, with many categories such as traditional acupuncture, electroacupuncture, laser acupuncture, and acupoint injection, has been shown to be relatively safe with few adverse effects. It is accessible and inexpensive, at least in China, and is likely to be widely used there for psychotic symptoms.
Objectives: To review the effects of acupuncture, alone or in combination treatments compared with placebo (or no treatment) or any other treatments for people with schizophrenia or related psychoses.
Selection criteria: We included all relevant randomised controlled trials involving people with schizophrenia-like illnesses, comparing acupuncture added to standard dose antipsychotics with standard dose antipsychotics alone, acupuncture added to low dose antipsychotics with standard dose antipsychotics, acupuncture with antipsychotics, acupuncture added to Traditional Chinese Medicine (TCM) drug with TCM drug, acupuncture with TCM drug, electric acupuncture convulsive therapy with electroconvulsive therapy.
Background: Children with severe global developmental delay (SGDD) have significant intellectual disability and severe motor impairment; they are extremely limited in their functional movement and are dependent upon others for all activities of daily living. SGDD does not directly cause lung dysfunction, but the combination of immobility, weakness, skeletal deformity and parenchymal damage from aspiration can lead to significant prevalence of respiratory illness. Respiratory pathology is a significant cause of morbidity and mortality for children with SGDD; it can result in frequent hospital admissions and impacts upon quality of life. Although many treatment approaches are available, there currently exists no comprehensive review of the literature to inform best practice. A broad range of treatment options exist; to focus the scope of this review and allow in-depth analysis, we have excluded pharmaceutical interventions.
Objectives: To assess the effects of non-pharmaceutical treatment modalities for the management of respiratory morbidity in children with severe global developmental delay.
Selection criteria: Randomised controlled trials, controlled trials and cohort studies of children up to 18 years of age with a diagnosis of severe neurological impairment and respiratory morbidity were included. Studies of airways clearance techniques, suction, assisted coughing, non-invasive ventilation, tracheostomy and postural management were eligible for inclusion.
Background: This is an update of the review on "Lidocaine for pain relief in burn injured patients" first published in Issue 3, 2007, and first updated in 2012. Pain is a major issue for people with many different types of wounds, in particular those people with burn injuries. Prompt, aggressive use of opioid analgesics such as morphine has been suggested as critical to avert the cycle of pain and anxiety, but adverse effects are encountered. It has been proposed that newer agents such as lidocaine could be effective in reducing pain and alleviating the escalating opioid dosage requirements in people with burn injury.
Objectives: To assess the safety and effectiveness of intravenous lidocaine as a means of pain relief versus no therapy, placebo, other drugs, or a combination of these therapies in people with burn injury.
Selection criteria: We included randomised controlled trials (RCTs) and controlled clinical trials (CCTs), published and unpublished, which assessed the efficacy of intravenous lidocaine in varying doses as a single-agent therapy with no therapy, placebo, other analgesics (such as opioids), lidocaine plus another drug, or a combination of these therapies as a means of pain relief in people with burn injury.
Background: Bacterial keratitis is a serious ocular infectious disease that can lead to severe visual disability. Risk factors for bacterial corneal infection include contact lens wear, ocular surface disease, corneal trauma, and previous ocular or eyelid surgery. Topical antibiotics constitute the mainstay of treatment in cases of bacterial keratitis, whereas the use of topical corticosteroids as an adjunctive therapy to antibiotics remains controversial. Topical corticosteroids are usually used to control inflammation using the smallest amount of the drug. Their use requires optimal timing, concomitant antibiotics, and careful follow-up.
Objectives: The objective of the review was to assess the effectiveness and safety of corticosteroids as adjunctive therapy for bacterial keratitis. Secondary objectives included evaluation of health economic outcomes and quality of life outcomes.
Selection criteria: We included randomized controlled trials (RCTs) that had evaluated adjunctive therapy with topical corticosteroids in people with bacterial keratitis who were being treated with antibiotics.
Background: Pharmaceuticals are important interventions that could improve people's health. Pharmaceutical pricing and purchasing policies are used as cost-containment measures to determine or affect the prices that are paid for drugs. Internal reference pricing establishes a benchmark or reference price within a country which is the maximum level of reimbursement for a group of drugs. Other policies include price controls, maximum prices, index pricing, price negotiations and volume-based pricing.
Objectives: To determine the effects of pharmaceutical pricing and purchasing policies on health outcomes, healthcare utilisation, drug expenditures and drug use.
Selection criteria: Policies in this review were defined as laws; rules; financial and administrative orders made by governments, non-government organisations or private insurers. To be included a study had to include an objective measure of at least one of the following outcomes: drug use, healthcare utilisation and health outcomes or costs (expenditures); the study had to be a randomised trial, non-randomised trial, interrupted time series (ITS), repeated measures (RM) study or a controlled before-after study of a pharmaceutical pricing or purchasing policy for a large jurisdiction or system of care.
Background: Idiopathic membranous nephropathy (IMN) is the most common form of nephrotic syndrome in adults. The disease shows a benign or indolent course in the majority of patients, with a rate of spontaneous complete or partial remission of nephrotic syndrome as high as 30% or more. Despite this, 30% to 40% of patients progress toward end-stage kidney disease (ESKD) within five to 15 years. The efficacy and safety of immunosuppression for IMN with nephrotic syndrome are still controversial. This is an update of a Cochrane review first published in 2004.
Objectives: The aim of this review was to evaluate the safety and efficacy of immunosuppressive treatments for adult patients with IMN and nephrotic syndrome. Moreover it was attempted to identify the best therapeutic regimen, when to start immunosuppression and whether the above therapies should be given to all adult patients at high risk of progression to ESKD or only restricted to those with impaired kidney function.
Selection criteria: Randomised controlled trials (RCTs) investigating the effects of immunosuppression in adults with IMN and nephrotic syndrome.
Background: Stroke affects 15 million people per year worldwide. Despite recent developments in acute stroke treatment, prevention remains very important. Stroke has a high rate of recurrence; therefore secondary prevention is also important. Many clinical approaches to control risk factors have been proposed. One of these approaches is the prescription of beta-blockers that have effects beyond the reduction of blood pressure, which can reduce the recurrence of stroke.
Objectives: To evaluate the efficacy of beta-blockers for preventing stroke recurrence and for reducing death and major vascular events in people with a previous stroke or transient ischaemic attack (TIA), and to determine their safety, particularly with regard to the development of diabetes mellitus.
Selection criteria: Randomised controlled trials (RCTs) that included participants with previous stroke or TIA due to arterial thrombosis or embolism. The intervention was any beta-blocker versus control, or beta-blocker plus other treatment versus other treatment.
Background: Chronic kidney disease (CKD) is a worldwide public health problem which is at high increased risk of cardiovascular disease (CVD) and renal failure. Deterioration of kidney function causes an increase in circulating toxins, which, in turn promotes the progression of CKD. Oral adsorbents with capacity to adsorb and remove substances including uraemic toxins from the intestine could be effective in minimising kidney injury.
Objectives: To investigate the benefits and harms of oral adsorbents for preventing or delaying the progression of CKD.
Selection criteria: Randomised controlled trials (RCTs) and quasi-RCTs comparing any oral adsorbents for preventing or delaying the progression of CKD.
Background: Allopurinol, a xanthine oxidase inhibitor, is considered one of the most effective urate-lowering drugs and is frequently used in the treatment of chronic gout.
Objectives: To assess the efficacy and safety of allopurinol compared with placebo and other urate-lowering therapies for treating chronic gout.
Selection criteria: All randomised controlled trials (RCTs) or quasi-randomised controlled clinical trials (CCTs) that compared allopurinol with a placebo or an active therapy in adults with chronic gout.
Background: Schizophrenia is a mental illness causing disordered beliefs, ideas and sensations. Many people with schizophrenia smoke cannabis, and it is unclear why a large proportion do so and if the effects are harmful or beneficial. It is also unclear what the best method is to allow people with schizophrenia to alter their cannabis intake.
Objectives: To assess the effects of specific psychological treatments for cannabis reduction in people with schizophrenia.To assess the effects of antipsychotics for cannabis reduction in people with schizophrenia.To assess the effects of cannabinoids (cannabis related chemical compounds derived from cannabis or manufactured) for symptom reduction in people with schizophrenia.
Selection criteria: We included all randomised controlled trials involving cannabinoids and schizophrenia/schizophrenia-like illnesses, which assessed:1) treatments to reduce cannabis use in people with schizophrenia;2) the effects of cannabinoids on people with schizophrenia.
Background: Endoscopic therapy reduces the rebleeding rate and the need for surgery in patients with bleeding peptic ulcers.
Objectives: To determine whether a second procedure improves haemostatic efficacy or patient outcomes or both after epinephrine injection in adults with high-risk bleeding ulcers.
Selection criteria: We included randomised controlled trials (RCTs) comparing epinephrine alone versus epinephrine plus a second method. Populations consisted of patients with high-risk bleeding peptic ulcers, that is, patients with haemorrhage from peptic ulcer disease (gastric or duodenal) with major stigmata of bleeding as defined by Forrest classification Ia (spurting haemorrhage), Ib (oozing haemorrhage), IIa (non-bleeding visible vessel) and IIb (adherent clot) (Forrest Ia-Ib-IIa-IIb).
Background: Functional dyspepsia (FD) has been a worldwide complaint. More effective therapies are needed with fewer adverse effects than are seen with conventional medications. Acupuncture, as a traditional therapeutic method, has been widely used for functional gastrointestinal disorders in the East. Manual acupuncture and electroacupuncture have been recognized treatments for FD, but to date, no robust evidence has been found for the effectiveness and safety of these interventions in the treatment of this condition.
Objectives: This review was conducted to assess the efficacy and safety of manual acupuncture and electroacupuncture in the treatment of FD.
Selection criteria: Randomized controlled trials (RCTs) were included if investigators reported efficacy and safety of manual acupuncture or electroacupuncture for patients with FD diagnosed by Rome II or Rome III criteria, compared with medications, blank control, or sham acupuncture.
Background: Pregnancy increases the risk of malaria and this is associated with poor health outcomes for both the mother and the infant, especially during the first or second pregnancy. To reduce these effects, the World Health Organization recommends that pregnant women living in malaria endemic areas sleep under insecticide-treated bednets, are treated for malaria illness and anaemia, and receive chemoprevention with an effective antimalarial drug during the second and third trimesters.
Objectives: To assess the effects of malaria chemoprevention given to pregnant women living in malaria endemic areas on substantive maternal and infant health outcomes. We also summarised the effects of intermittent preventive treatment with sulfadoxine-pyrimethamine (SP) alone, and preventive regimens for Plasmodium vivax.
Selection criteria: Randomized controlled trials (RCTs) and quasi-RCTs of any antimalarial drug regimen for preventing malaria in pregnant women living in malaria-endemic areas compared to placebo or no intervention. In the mother, we sought outcomes that included mortality, severe anaemia, and severe malaria; anaemia, haemoglobin values, and malaria episodes; indicators of malaria infection, and adverse events. In the baby, we sought foetal loss, perinatal, neonatal and infant mortality; preterm birth and birthweight measures; and indicators of malaria infection. We included regimens that were known to be effective against the malaria parasite at the time but may no longer be used because of parasite drug resistance.
Background: Pain is the most common symptom in the emergency setting; however, timely management of acute pain in children continues to be suboptimal. Intranasal drug delivery has emerged as an alternative method of achieving quicker drug delivery without adding to the distress of a child by inserting an intravenous cannula.
Objectives: We identified and evaluated all randomized controlled trials (RCTs) and quasi-randomized trials to assess the effects of intranasal fentanyl (INF) versus alternative analgesic interventions in children with acute pain, with respect to reduction in pain score, occurrence of adverse events, patient tolerability, use of "rescue analgesia," patient/parental satisfaction and patient mortality.
Selection criteria: We included RCTs comparing INF versus any other pharmacological/non-pharmacological intervention for the treatment of children in acute pain (aged < 18 years).
Background: Hepatitis B vaccine has been recommended for use in people living with HIV (PLHIV) mostly because of the similarities in routes of infection and their prevalence in the same geographic areas. PLHIV may not develop sero-protection after receiving standard hepatitis B vaccine due to their compromised immune status.
Objectives: To evaluate the efficacy of hepatitis B virus vaccine in PLHIV compared to placebo or no vaccine.
Selection criteria: Randomised controlled trials of hepatitis B vaccine compared to placebo or no vaccine, evaluating relevant outcomes of efficacy and safety.
