Heritability describes the proportion of variance in risk developing a condition that is explained by genetic factors. Although amyotrophic lateral sclerosis (ALS) known to have complex origin, disease heritability remains unclear.To determine extent ALS and assess association sex with transmission.A prospective population-based parent-offspring study was conducted from January 1, 2008, December 31, 2017 heritability, first context gene mutations large effect. A total 1123 incident cases...

Abstract First- and second-degree relatives of people with amyotrophic lateral sclerosis report higher rates neuropsychiatric disorders, indicating that risk genes may be pleiotropic, causing multiple phenotypes within kindreds. Such constitute a disease endophenotype associates liability. We have directly investigated cognitive functioning traits among to identify potential endophenotypes the disease. In family-based, cross-sectional study design, first- (n = 149) were compared controls 60)...

Abstract Background Abdominal aortic aneurysm (AAA) is characterised by a bulging in the wall. AAA typically asymptomatic until rupture, which associated with very high mortality rate (approximately 80%). In context of an ageing population and increasing life expectancy, innovative approaches to early detection intervention are needed. The aim this review was assess clinical effectiveness safety one-time ultrasound screening for men. Methods Systematic searches were conducted electronic...
