Review Meta AnalysisInterventions for deliberately altering blood pressure in acute stroke.
It is unclear whether blood pressure should be altered actively during the acute phase of stroke. This is an update of a Cochrane review first published in 1997, and previously updated in 2001. ⋯ There is insufficient evidence to evaluate the effect of altering blood pressure on outcome during the acute phase of stroke. In patients with acute stroke, CCBs, ACEI, ARA and GTN each lower blood pressure while phenylephrine probably increases blood pressure.

Review Meta AnalysisGalactomannan detection for invasive aspergillosis in immunocompromized patients.
Invasive aspergillosis (IA) is the most common life-threatening opportunistic invasive mycosis in immunocompromized patients. A test for IA needs to be not too invasive and not too big a burden for the already weakened patient. The serum galactomannan ELISA seems to have potential for both requirements. ⋯ At a cut-off value 0.5 ODI in a population of 100 patients with a disease prevalence of 8% (overall median prevalence), 2 patients who have IA, will be missed (sensitivity 78%, 22% false negatives), and 17 patients will be treated or further referred unnecessarily (specificity of 81%, 19% false negatives). If we use the test at cut-off value 1.5 in the same population, that will mean that 3 IA patients will be missed (sensitivity 64%, 36% false negatives) and 5 patients will be treated or referred unnecessarily (specificity of 95%, 5% false negatives). These numbers should however be interpreted with caution, because the results were very heterogeneous.

Review Meta AnalysisElectromechanical and robot-assisted arm training for improving arm function and activities of daily living after stroke.
Electromechanical and robot-assisted arm training devices are used in rehabilitation and might help to improve arm function after stroke. ⋯ Patients who receive electromechanical and robot-assisted arm training after stroke are not more likely to improve their activities of daily living, but arm motor function and strength of the paretic arm may improve. However, the results must be interpreted with caution because there were variations between the trials in the duration, amount of training and type of treatment, and in the patient characteristics.

Most ischaemic strokes are caused by blood clots blocking an artery in the brain. Clot prevention with anticoagulants might improve outcome if bleeding risks were low. This is an update of a Cochrane review first published in 1995, and previously updated in 2004. ⋯ Since the last version of the review, neither of the two new relevant studies have provided additional information to change the conclusions. In patients with acute ischaemic stroke, immediate anticoagulant therapy is not associated with net short or long-term benefit. Treatment with anticoagulants reduced recurrent stroke, deep vein thrombosis and pulmonary embolism, but increased bleeding risk. The data do not support the routine use of any the currently available anticoagulants in acute ischaemic stroke.

Review Meta AnalysisInterventions for Old World cutaneous leishmaniasis.
Cutaneous leishmaniasis is caused by a parasitic infection and is considered one of the most serious skin diseases in many developing countries. Antimonials are the most commonly prescribed treatment but other drugs have been used with varying success. ⋯ Most trials have been designed and reported poorly, resulting in a lack of evidence for potentially beneficial treatments. There is a desperate need for large well conducted studies that evaluate long-term effects of current therapies. We suggest the creation of an international platform to improve quality and standardization of future trials in order to inform clinical practice.
