Review Meta AnalysisAnkle-foot orthoses for improving walking in adults with calf muscle weakness due to neuromuscular disorders.
Calf muscle weakness is a common symptom in slowly progressive neuromuscular disorders that lead to walking problems like instability and increased walking effort. The mainstay of treatment to improve walking in this population is the provision of ankle-foot-orthoses (AFOs). Since we are not aware of an up-to-date and complete overview of the effects of AFOs used for calf muscle weakness in slowly progressive neuromuscular disorders, we reviewed the evidence for the effectiveness of AFOs to improve walking in this patient group, in order to support clinical decision-making. ⋯ The available evidence for ankle-foot orthoses (AFOs) to improve walking in adults with calf muscle weakness comes from a limited number of small studies with heterogeneity in intervention characteristics and outcome assessment, and is of low to very low certainty. The evidence suggests that carbon AFOs may reduce walking energy cost (effort), increase walking speed, and enhance satisfaction, and leather AFOs may increase walking speed, while polypropylene and elastic AFOs may make little or no difference to walking speed. We are unable to draw conclusions about the effects of AFOs on perceived walking effort, balance, and use. Nor can we draw conclusions about adverse effects of using AFOs. The variety in the findings for AFOs made of different materials suggests further investigation is warranted to explore how different AFO materials impact walking improvement in people with calf muscle weakness due to slowly progressive neuromuscular disorders.

Transtracheal ultrasound for identifying endotracheal intubation in adults.
This is a protocol for a Cochrane Review (diagnostic). The objectives are as follows: To determine the diagnostic accuracy of transtracheal ultrasound for detecting endotracheal intubation in adult patients. Secondary objectives Secondary objectives include assessing the diagnostic accuracy of transtracheal ultrasound amongst the following subgroups: setting (e.g. prehospital, emergency department, intensive care unit, operating room) operator specialty (e.g. emergency medicine, non-emergency medicine) operator experience (e.g. attending physician, resident physician, non-physician) ultrasound technique (e.g. static, dynamic) ultrasound transducer (e.g. curvilinear, linear).

Review Meta AnalysisTranexamic acid for preventing postpartum haemorrhage after vaginal birth.
Postpartum haemorrhage (PPH) is common and potentially life-threatening. The antifibrinolytic drug tranexamic acid (TXA) is thought to be effective for treating PPH. There is growing interest in whether TXA is effective for preventing PPH after vaginal birth. In randomised controlled trials (RCTs), TXA has been associated with increased risk of seizures and unexplained increased mortality when given more than three hours after traumatic bleeding. Reliable evidence on the effects, cost-effectiveness and safety of prophylactic TXA is required before considering widespread use. This review updates one published in 2015. ⋯ Protocol (2009) DOI: 10.1002/14651858.CD007872 Original review (2010) DOI: 10.1002/14651858.CD007872.pub2 Review update (2015) DOI: 10.1002/14651858.CD007872.pub3.
