UNLABELLED Most cases of hepatitis E viral (HEV) infection in developed countries are autochthonous. Nevertheless, the reported seroprevalence of HEV varies greatly depending on the geographical area and the performance of the immunoassay used. We used validated assays to determine the prevalence of anti-HEV immunoglobulin G (IgG) and IgM among 10,569(More)
This paper considers the problem of finding a meaningful template function that represents the common pattern of a sample of curves. To address this issue, a novel algorithm based on a robust version of the isometric featuring mapping (Isomap) algorithm is developed. Assuming that the functional data lie on an intrinsically low-dimensional smooth manifold(More)
This study has two objectives. First, to analyse the respective roles of parental BMI and the wider environment on children's BMI across childhood, using a counterfactual analysis. Second, to determine if the correlations between parents and offspring BMI are partly environmental. We used data on 4437 girls and 4337 boys born in 2000-2001 in the UK and(More)
AIM The constituents of weight loss following bariatric surgery are poorly known. There is an expectation of a limited loss of lean body mass (LBM), and a significant loss of fat mass (FM) as well as muscle mass (MM), which could lead to functional loss and metabolic impairment. This prospective study analysed the determinants of MM changes after Roux-en-Y(More)
BACKGROUND Abnormal glucose profiles have been described after Roux-en-Y gastric bypass (RYGB) with intense postprandial hyperglycemic peaks in some but not all the patients. The underlying mechanisms of these anomalies are not totally understood. OBJECTIVE The aim of this study is to determine whether or not the composition of the meal impacts the(More)
