- OBJECTIVE: The objective of this study was to assess the level of agreement between stroke subtype classifications made using the Trial of Org 10172 Acute Stroke Treatment (TOAST) and Causative Classification of Stroke (CCS) systems. METHODS: Study subjects included 13,596 adult men and women accrued from 20 US and European genetic research centers participating in the National Institute of Neurological Disorders and Stroke (NINDS) Stroke Genetics Network (SiGN). All cases had independently classified TOAST and CCS stroke subtypes. Kappa statistics were calculated for the 5 major ischemic stroke subtypes common to both systems. RESULTS: The overall agreement between TOAST and CCS was moderate (agreement rate, 70%; κ = 0.59, 95% confidence interval [CI] 0.58-0.60). Agreement varied widely across study sites, ranging from 28% to 90%. Agreement on specific subtypes was highest for large-artery atherosclerosis (κ = 0.71, 95% CI 0.69-0.73) and lowest for small-artery occlusion (κ = 0.56, 95% CI 0.54-0.58). CONCLUSION: Agreement between TOAST and CCS diagnoses was moderate. Caution is warranted when comparing or combining results based on the 2 systems. Replication of study results, for example, genome-wide association studies, should utilize phenotypes determined by the same classification system, ideally applied in the same manner.

Multi-ethnic genome-wide association study for atrial fibrillation

- Atrial fibrillation (AF) affects more than 33 million individuals worldwide(1) and has a complex heritability(2). We conducted the largest meta-analysis of genome-wide association studies (GWAS) for AF to date, consisting of more than half a million individuals, including 65,446 with AF. In total, we identified 97 loci significantly associated with AF, including 67 that were novel in a combined-ancestry analysis, and 3 that were novel in a European-specific analysis. We sought to identify AF-associated genes at the GWAS loci by performing RNA-sequencing and expression quantitative trait locus analyses in 101 left atrial samples, the most relevant tissue for AF. We also performed transcriptome-wide analyses that identified 57 AF-associated genes, 42 of which overlap with GWAS loci. The identified loci implicate genes enriched within cardiac developmental, electrophysiological, contractile and structural pathways. These results extend our understanding of the biological pathways underlying AF and may facilitate the development of therapeutics for AF.

Mental health care for irregular migrants in Europe : Barriers and how they are overcome

Journal article (peer-reviewed)abstract
- BackgroundIrregular migrants (IMs) are exposed to a wide range of risk factors for developing mental health problems. However, little is known about whether and how they receive mental health care across European countries. The aims of this study were (1) to identify barriers to mental health care for IMs, and (2) to explore ways by which these barriers are overcome in practice.MethodsData from semi-structured interviews with 25 experts in the field of mental health care for IMs in the capital cities of 14 European countries were analysed using thematic analysis.ResultsExperts reported a range of barriers to mental health care for IMs. These include the absence of legal entitlements to health care in some countries or a lack of awareness of such entitlements, administrative obstacles, a shortage of culturally sensitive care, the complexity of the social needs of IMs, and their fear of being reported and deported. These barriers can be partly overcome by networks of committed professionals and supportive services. NGOs have become important initial points of contact for IMs, providing mental health care themselves or referring IMs to other suitable services. However, these services are often confronted with the ethical dilemma of either acting according to the legislation and institutional rules or providing care for humanitarian reasons, which involves the risk of acting illegally and providing care without authorisation.ConclusionsEven in countries where access to health care is legally possible for IMs, various other barriers remain. Some of these are common to all migrants, whilst others are specific for IMs. Attempts at improving mental health care for IMs should consider barriers beyond legal entitlement, including communicating information about entitlement to mental health care professionals and patients, providing culturally sensitive care and ensuring sufficient resources.
