ReviewSealing procedures for preterm prelabour rupture of membranes.
Preterm prelabour rupture of the membranes (PPROM) complicates approximately 2% of pregnancies and can be either spontaneous or iatrogenic in nature. Complications of PPROM include prematurity, chorioamnionitis, neonatal sepsis, limb position defects, respiratory distress syndrome, pulmonary hypoplasia chronic lung disease, periventricular leukomalacia and intraventricular haemorrhage.A number of different sealing techniques have been employed which aim to restore a physical barrier against infection and encourage the re-accumulation of amniotic fluid. Routine use of sealants is currently not recommended due to a lack of sufficient evidence to support the safety and effectiveness of such interventions. ⋯ There is insufficient evidence to evaluate sealing procedures for PPROM. There were no data relating to this review's primary outcome (perinatal mortality) and the majority of our infant and maternal secondary outcomes were not reported in the two included studies.There was limited evidence to suggest that an immunological membrane sealant was associated with a reduction in preterm birth at less than 37 weeks and neonatal death, but these results should be interpreted with caution as this is based on one small study, with a high risk of bias, and the intervention has not been tested in other studies.Although midtrimester PPROM is not a rare occurrence, there are only a small amount of published data addressing the benefits and risks of sealing procedures. Most of these studies are retrospective and cohort based and could therefore not be included in our data-analysis.This review highlights the paucity of prospective randomised trials in this area. Current evidence provides limited information both on effectiveness and safety for the interventions described. Given the paucity of high-quality data, we recommend that future research efforts focus on the conduct of randomised trials assessing the effect of promising interventions that have been only evaluated to date in cohort studies (e.g. amniopatch). Future trials should address outcomes including perinatal mortality, preterm birth, neonatal death, respiratory distress syndrome, neonatal sepsis and developmental delay. They should also evaluate maternal outcomes including sepsis, mode of delivery, length of hospital stay and emotional well-being.

Review Meta AnalysisAmbulatory and short-burst oxygen for interstitial lung disease.
A large subgroup of people with interstitial lung disease (ILD) are normoxic at rest, but rapidly desaturate on exertion. This can limit exercise capacity and worsen dyspnoea. The use of ambulatory or short-burst oxygen when mobilising or during other activities, may improve exercise capacity and relieve dyspnoea. ⋯ This review found no evidence to support or refute the use of ambulatory or short burst oxygen in ILD due to the limited number of included studies and data. Further research is needed to examine the role of this treatment.

ReviewTranscutaneous electrical stimulation (TES) for treatment of constipation in children.
Childhood constipation is a common problem with substantial health, economic and emotional burdens. Existing therapeutic options, mainly pharmacological, are not consistently effective, and some are associated with adverse effects after prolonged use. Transcutaneous electrical stimulation (TES), a non-pharmacological approach, is postulated to facilitate bowel movement by modulating the nerves of the large bowel via the application of electrical current transmitted through the abdominal wall. ⋯ The very low quality evidence gathered in this review does not suggest that TES provides a benefit for children with chronic constipation. Further randomized controlled trials assessing TES for the management of childhood constipation should be conducted. Future trials should include clear documentation of methodologies, especially measures to evaluate the effectiveness of blinding, and incorporate patient-important outcomes such as the number of patients with improved CSBM, improved clinical symptoms and quality of life.

Review Meta AnalysisActive cycle of breathing technique for cystic fibrosis.
People with cystic fibrosis experience chronic airway infections as a result of mucus build up within the lungs. Repeated infections often cause lung damage and disease. Airway clearance therapies aim to improve mucus clearance, increase sputum production, and improve airway function. The active cycle of breathing technique (also known as ACBT) is an airway clearance method that uses a cycle of techniques to loosen airway secretions including breathing control, thoracic expansion exercises, and the forced expiration technique. This is an update of a previously published review. ⋯ There is insufficient evidence to support or reject the use of the active cycle of breathing technique over any other airway clearance therapy. Five studies, with data from eight different comparators, found that the active cycle of breathing technique was comparable with other therapies in outcomes such as participant preference, quality of life, exercise tolerance, lung function, sputum weight, oxygen saturation, and number of pulmonary exacerbations. Longer-term studies are needed to more adequately assess the effects of the active cycle of breathing technique on outcomes important for people with cystic fibrosis such as quality of life and preference.

Review Meta AnalysisSelf-monitoring and self-management of oral anticoagulation.
The introduction of point-of-care devices for the management of patients on oral anticoagulation allows self-testing by the patient at home. Patients who self-test can either adjust their medication according to a pre-determined dose-INR (international normalized ratio) schedule (self-management), or they can call a clinic to be told the appropriate dose adjustment (self-monitoring). Increasing evidence suggests self-testing of oral anticoagulant therapy is equal to or better than standard monitoring. This is an updated version of the original review published in 2010. ⋯ Participants who self-monitor or self-manage can improve the quality of their oral anticoagulation therapy. Thromboembolic events were reduced, for both those self-monitoring or self-managing oral anticoagulation therapy. A reduction in all-cause mortality was observed in trials of self-management but not in self-monitoring, with no effects on major haemorrhage.
