Review Meta AnalysisComputed tomography angiography or magnetic resonance angiography for detection of intracranial vascular malformations in patients with intracerebral haemorrhage.
Intracranial vascular malformations (brain or pial/dural arteriovenous malformations/fistulae, and aneurysms) are the leading cause of intracerebral haemorrhage (ICH) in young adults. Early identification of the intracranial vascular malformation may improve outcome if treatment can prevent ICH recurrence. Catheter intra-arterial digital subtraction angiography (IADSA) is considered the reference standard for the detection an intracranial vascular malformation as the cause of ICH. Computed tomography angiography (CTA) and magnetic resonance angiography (MRA) are less invasive than IADSA and may be as accurate for identifying some causes of ICH. ⋯ CTA and MRA appear to have good sensitivity and specificity following ICH for the detection of intracranial vascular malformations, although several of the included studies had methodological shortcomings (retrospective designs and partial verification bias in particular) that may have increased apparent test accuracy.

The early period following the onset of acute coronary syndrome (ACS) represents a critical stage of coronary heart disease, with a high risk of recurrent events and deaths. The short-term effects of early treatment with statins on patient-relevant outcomes in patients suffering from ACS are unclear. This is an update of a review previously published in 2011. ⋯ Based on moderate quality evidence, due to concerns about risk of bias and imprecision, initiation of statin therapy within 14 days following ACS does not reduce death, myocardial infarction, or stroke up to four months, but reduces the occurrence of unstable angina at four months following ACS. Serious side effects were rare.

ReviewFlupenthixol versus low-potency first-generation antipsychotic drugs for schizophrenia.
Antipsychotic drugs are the core treatment for schizophrenia. Treatment guidelines state that there is no difference in efficacy between antipsychotic drugs, however, low-potency antipsychotic drugs are sometimes perceived as less efficacious than high-potency compounds by clinicians, and they also seem to differ in their side effects. ⋯ The evidence base of flupenthixol versus low-potency first-generation antipsychotics is currently restricted to one randomised comparison with chlorpromazine. The few reported data do not suggest a difference in efficacy, but flupenthixol appeared to produce more movement disorders and dizziness, while chlorpromazine was associated with the anticholinergic side effect - dryness of mouth. More trials are needed to make conclusions about the relative effects of flupenthixol and low-potency antipsychotics.
