Review Meta AnalysisParenteral anticoagulation for prolonging survival in patients with cancer who have no other indication for anticoagulation.
Basic research and clinical studies have generated the hypothesis that anticoagulation may improve survival in patients with cancer through an antitumour effect in addition to the antithrombotic effect. ⋯ Heparin has a survival benefit in cancer patients in general, and in patients with limited small cell lung cancer in particular. Heparin might be particularly beneficial in cancer patients with limited cancer or a longer life expectancy. Future research should investigate the survival benefit of different types of anticoagulants (in different dosing, schedules and duration of therapy) in patients with different types and stages of cancers.

Review Meta AnalysisAnalgesia in patients with acute abdominal pain.
For decades, analgesia for patients with acute abdominal pain was withheld until a definitive diagnosis was established for fear of masking the symptoms, changing physical findings or ultimately delaying diagnosis and treatment of a surgical condition. This non-evidence-based approach has been challenged by recent studies demonstrating that the use of analgesia in the initial evaluation of patients with acute abdominal pain leads to significant pain reduction without affecting diagnostic accuracy. However, early administration of analgesia to such patients can greatly reduce their pain and does not interfere with a diagnosis, which may even be facilitated due to the severity of physical symptoms being reduced. ⋯ The review provide some evidence to support the notion that the use of opioid analgesics in patients with acute abdominal pain is helpful in terms of patient comfort and does not retard decisions to treat.

Review Meta AnalysisPrimary closure versus T-tube drainage after open common bile duct exploration.
Between 5% and 11% of people undergoing cholecystectomy have common bile duct stones. Open common bile duct exploration is an important operation when endoscopic retrograde cholangio-pancreatography fails or when expertise for laparoscopic common bile duct exploration is not available. The optimal method for performing open common bile duct exploration is unclear. ⋯ Primary closure after common bile duct exploration seems at least as safe as T-tube drainage. We need randomised trials that assess whether stents may offer benefits.

Review Meta AnalysisExercise for improving balance in older people.
Diminished ability to maintain balance may be associated with an increased risk of falling. In older adults, falls commonly lead to injury, loss of independence, associated illness and early death. Although some exercise interventions with balance and muscle strengthening components have been shown to reduce falls it is not known which elements, or combination of elements, of exercise interventions are most effective for improving balance in older people. ⋯ Exercise appears to have statistically significant beneficial effects on balance ability in the short term but the strength of evidence contained within these trials is limited. Many of these mainly small studies demonstrated a range of methodological weaknesses. The failure across the included studies to apply a core set of standardised outcome measures to determine balance ability restricts the capacity to compare or pool different trials from which firm conclusions regarding efficacy can be made. Further standardisation in timing of outcome assessment is also required as is longer term follow-up of outcomes to determine any lasting effects.

Review Meta AnalysisHome safety education and provision of safety equipment for injury prevention.
In industrialised countries injuries are the leading cause of childhood death and steep social gradients exist in child injury mortality and morbidity. The majority of injuries in pre-school children occur at home, but there is little meta-analytic evidence that child home safety interventions improve a range of safety practices or reduce injury rates and little evidence on their effect by social group. ⋯ Home safety education provided most commonly as one-to-one, face-to-face education, in a clinical setting or at home, especially with the provision of safety equipment is effective in increasing a range of safety practices. There is a lack of evidence regarding its impact on child injury rates. There was no consistent evidence that home safety education, with or without the provision of safety equipment was less effective in those at greater risk of injury.
