Multicenter evaluation of light transmission platelet aggregation reagents: communication from the ISTH SSC Subcommittee on Platelet Physiology.

Background: Light transmission aggregation (LTA) is used widely by the clinical and research communities. Although it is a gold standard, there is a lack of interlaboratory harmonization.

Objectives: The primary objective was to assess whether sources of activators (mainly adenosine diphosphate [ADP], collagen, arachidonic acid, epinephrine, and thrombin receptor activating peptide6) and ristocetin contribute to poor LTA reproducibility.

Clinical management and disease-modifying treatment for amyotrophic lateral sclerosis in African hospital centers: the TROPALS study.

To assess the availability of health workers and medications for clinical management of amyotrophic lateral sclerosis (ALS) in African hospital centers. Availability and affordability analyses of disease-modifying treatments were performed. : A multicenter observational study involving African hospitals was conducted.

Characteristics and Prognosis of Oldest Old Subjects with Amyotrophic Lateral Sclerosis.

Background: Amyotrophic Lateral Sclerosis (ALS) is an age-related neurodegenerative disease with unclear characteristics and prognosis in the oldest old (80 years and over). The aim of this study was to compare the oldest old and younger ALS patients in terms of clinical and socio-demographic characteristics, and prognosis.

Methods: ALS incident cases from the register of ALS in Limousin (FRALim), diagnosed between January 2000 and July 2013, were included.

Exploring the diagnosis delay and ALS functional impairment at diagnosis as relevant criteria for clinical trial enrolment.

Unlabelled: Objectives were: i) to describe the phenotypic heterogeneity of incident amyotrophic lateral sclerosis (ALS) patients diagnosed in 2012 in French ALS centres; ii) to look at the associations between ALSFRS-R score and ALSFRS-R slope (ΔFS) at time of diagnosis with diagnosis delay, ALS phenotypes and Airlie House diagnosis criteria (AHDC); iii) to describe the rate of progression on ΔFS, according to diagnosis delay.

Methods: Incident ALS cases diagnosed in French ALS centres were included. The rate of progression was evaluated as follows: ΔFS = (48 - ALSFRS-R at time of diagnosis)/duration from onset to diagnosis (months).

Epidemiological evidence that physical activity is not a risk factor for ALS.

To elucidate whether physical activity (PA) and sport increase the risk of developing amyotrophic lateral sclerosis (ALS), a literature review of epidemiological studies was conducted according to the Meta-analysis of Observational Studies in Epidemiology guidelines. Six databases (Pubmed, Scopus, ScienceDirect, IngentaConnect, Refdoc and the Cochrane database) were searched to April 2014. Experts were asked to identify studies in press.

Prognostic value of early epileptic seizures on mortality and functional disability in acute stroke: the Dijon Stroke Registry (1985-2010).

We aimed to evaluate the prognostic value of early epileptic seizures after stroke. All consecutive patients with a first-ever stroke were prospectively identified within the population of Dijon, France, thanks to a population-based registry, from 1985 to 2010. Early epileptic seizures were defined as seizures occurring within 14 days after stroke onset.
