CONTEXT Free T3 (FT3) has been positively associated with body mass index (BMI) in cross-sectional studies in healthy individuals. This is difficult to reconcile with clinical findings in pathological thyroid dysfunction. OBJECTIVE We aimed to investigate whether childhood adiposity influences FT3 levels. DESIGN Mendelian randomization using genetic(More)
OBJECTIVES To characterize the dynamics of the pituitary-adrenal interaction during the course of coronary artery bypass grafting both on and off pump. Since our data pointed to a major change in adrenal responsiveness to adrenocorticotropic hormone, we used a reverse translation approach to investigate the molecular mechanisms underlying this change in a(More)
PURPOSE Bevacizumab as an adjunct to chemotherapy improves survival for some patients with metastatic colorectal cancer. Immunohistochemical staining of samples from the registration ECOG E3200 trial of bevacizumab with FOLFOX demonstrated that only patients with carcinomas expressing low levels of VEGF-A165b, an anti-angiogenic splice variant of the(More)
Diabetic nephropathy (DN) is the leading cause of kidney failure in the world. To understand important mechanisms underlying this condition, and to develop new therapies, good animal models are required. In mouse models of type 1 diabetes, the DBA/2J strain has been shown to be more susceptible to develop kidney disease than other common strains. We(More)
We present a prenatal predictive diagnosis of Prader-Willi syndrome arising as a result of maternal heterodisomy for chromosome 15. The diagnosis arose following chorionic villus sampling which showed a mosaic trisomy 15 karyotype with a chromosomally normal follow-up amninocentesis. Molecular studies on DNA extracted from cultured amniocytes showed no(More)
BACKGROUND Deviation from the physiological glucocorticoid dynamics (circadian and underlying ultradian rhythmicity) is a common characteristic of various neuropsychiatric and endocrine disorders as well as glucocorticoid-based therapeutics. These states may be accompanied by neuropsychiatric symptomatology, suggesting continuous dynamic glucocorticoid(More)
Context Serum thyroid hormone levels differ between children and adults, but have not been studied longitudinally through childhood. Objective To assess changes in thyroid-stimulating hormone (TSH) and thyroid hormone levels over childhood and their interrelationships. Design Cohort study. Setting The Avon Longitudinal Study of Parents and Children, a(More)
INTRODUCTION Sickle cell disease in pregnancy carries a high risk of maternal and fetal adverse outcomes. The use of prophylactic transfusions to reduce the risk of sickle complications is controversial. Current UK standards do not recommend the routine use of transfusion for sickle pregnancy. We examined transfusion episodes during sickle pregnancies in a(More)
BACKGROUND We have observed that Doctors often perceive that cystic fibrosis (CF) is exceptionally rare in non-whites, and that this bias has repeatedly resulted in diagnostic delay. We therefore compared the age at diagnosis, genetic features and relative prevalence of CF in non-whites and white patients in the West Midlands. METHODS Analysis of data on(More)
