Randomized Controlled Trial Multicenter Study
Opicapone as an adjunct to levodopa in patients with Parkinson's disease and end-of-dose motor fluctuations: a randomised, double-blind, controlled trial.
Opicapone is a novel, once-daily, potent third-generation catechol-O-methyltransferase inhibitor. We aimed to assess the safety and efficacy of opicapone as an adjunct to levodopa compared with placebo or entacapone in patients with Parkinson's disease and motor fluctuations. ⋯ BIAL.

For about 30% of patients with epilepsy the cause is unknown. Even in patients with a known risk factor for epilepsy, such as ischaemic stroke, only a subpopulation of patients develops epilepsy. ⋯ Injury severity, location and type of pathological changes, genetic factors, and pre-injury and post-injury exposure to non-genetic factors (ie, the exposome) can divide patients with ischaemic stroke into different endophenotypes with a variable risk for epileptogenesis. These data provide guidance for animal modelling of post-stroke epilepsy, and for laboratory experiments to explore with increased specificity the molecular 'mechanisms, biomarkers, and treatment targets of post-stroke epilepsy in different circumstances, with the aim of modifying epileptogenesis after ischaemic stroke in individual patients without compromising recovery.

At present, no effective cure or prophylaxis exists for Alzheimer's disease. Symptomatic treatments are modestly effective and offer only temporary benefit. Advances in induced pluripotent stem cell (iPSC) technology have the potential to enable development of so-called disease-in-a-dish personalised models to study disease mechanisms and reveal new therapeutic approaches, and large panels of iPSCs enable rapid screening of potential drug candidates. ⋯ In 2015, the US Food and Drug Administration granted investigational new drug approval for the first phase 2A clinical trial of ischaemia-tolerant mesenchymal stem cells to treat Alzheimer's disease in the USA. Similar trials are either underway or being planned in Europe and Asia. Although safety and ethical concerns remain, we call for the acceleration of human stem cell-based translational research into the causes and potential treatments of Alzheimer's disease.

Meta Analysis
Clinical course of untreated cerebral cavernous malformations: a meta-analysis of individual patient data.
Cerebral cavernous malformations (CCMs) can cause symptomatic intracranial haemorrhage (ICH), but the estimated risks are imprecise and predictors remain uncertain. We aimed to obtain precise estimates and predictors of the risk of ICH during untreated follow-up in an individual patient data meta-analysis. ⋯ UK Medical Research Council, Chief Scientist Office of the Scottish Government, and UK Stroke Association.
