Review Meta AnalysisAnticoagulants versus antiplatelet agents for acute ischaemic stroke.
Antiplatelet agents produce a small, but worthwhile benefit in long-term functional outcome and survival, and have become standard treatment for acute ischaemic stroke. Anticoagulants are often used as an alternative treatment, despite evidence that they are ineffective in producing long-term benefits. We wanted to review trials which have directly compared anticoagulants and antiplatelet agents, to assess whether any anticoagulant regimen offers net advantages over antiplatelet agents, overall or in some particular category of patients (e.g. patients with atrial fibrillation). ⋯ Anticoagulants offered no net advantages over antiplatelet agents in acute ischaemic stroke. The combination of low-dose UFH and aspirin appeared in a subgroup analysis to be associated with net benefits compared with aspirin alone, and this merits further research.

Review Meta AnalysisDopamine for prevention of morbidity and mortality in term newborn infants with suspected perinatal asphyxia.
Perinatal asphyxia remains an important condition with significant mortality and long-term morbidity. Multisystem involvement including hypotension and low cardiac output is common in infants with perinatal asphyxia. Dopamine is commonly used for infants with hypotension of any etiology, with the goal of improving cardiac output and preventing its detrimental consequences. ⋯ There is currently insufficient evidence from randomised controlled trials that the use of dopamine in term infants with suspected perinatal asphyxia improves mortality or long-term neurodevelopmental outcome. The question of whether dopamine improves outcome for term infants with suspected perinatal asphyxia has not been answered. Further research is required to determine whether or not the use of dopamine improves mortality and long-term morbidity for these infants and if so, issues such as which infants, at what dose and with what co-interventions should be addressed.

Although several rehabilitation programs, physical fitness programs or protocols regarding instruction for patients to return to work after lumbar disc surgery have been suggested, little is known about the efficacy and effectiveness of these treatments. There are still persistent fears of causing re-injury, re-herniation, or instability. ⋯ There is no evidence that patients need to have their activities restricted after first time lumbar disc surgery. There is strong evidence for intensive exercise programs (at least if started about 4-6 weeks post-operative) on short term for functional status and faster return to work and there is no evidence they increase the re-operation rate. It is unclear what the exact content of post-surgery rehabilitation should be. Moreover, there are no studies that investigated whether active rehabilitation programs should start immediately post-surgery or possibly four to six weeks later.

ReviewNon-steroidal anti-inflammatory drugs (NSAIDs) for treating lateral elbow pain in adults.
Lateral elbow pain, or tennis elbow, is a common condition causing pain in the elbow and forearm and lack of strength and function of the elbow and wrist. It is often treated with non-steroidal anti-inflammatory drugs (NSAIDs), either orally or by topical application. ⋯ There is some support for the use of topical NSAIDs to relieve lateral elbow pain at least in the short term. There remains insufficient evidence to recommend or discourage the use of oral NSAID, although it appears injection may be more effective than oral NSAID in the short term. A direct comparison between topical and oral NSAID has not been made and so no conclusions can be drawn regarding the best method of administration.

ReviewHeliox for treatment of exacerbations of chronic obstructive pulmonary disease.
Due to its low density properties, helium-oxygen mixtures have the potential to decrease the work of breathing and possibly avoid the need for intubation and mechanical ventilation in patients with respiratory failure. ⋯ There is currently insufficient evidence to support the use of helium-oxygen mixtures to treat acute exacerbations of COPD in either ventilated or nonventilated patients. Suitably designed randomised controlled trials with the endpoint being the avoidance of mechanical ventilation may be justified.
