Opt-out provider-initiated HIV testing and counselling in primary care outpatient clinics in Zambia.
OBJECTIVE To increase case-finding of infection with human immunodeficiency virus (HIV) in Zambia and their referral to HIV care and treatment by supplementing existing client-initiated voluntary counselling and testing (VCT), the dominant mode of HIV testing in the country. METHODS Lay counsellors offered provider-initiated HIV testing and counselling (PITC) to all outpatients who attended p...
Kinetic methods in unanesthetized rodents have shown that turnover rates of arachidonic acid (AA) and docosahexaenoic acid (DHA) in brain membrane phospholipids are rapid and energy consuming and that phospholipase A2 (PLA2) and acyl-CoA synthetase enzymes that regulate turnover are specific for one or the other PUFA. Thus, AA turnover in brain phospholipids was reduced, and AA-selective cytoso...
Choices for delivery care are made based on the available resources and influence health outcomes of women and their children. The aim of the paper is to study utilization and preference for delivery care and related factors in one urban and one rural area of northern Vietnam. Two cohorts of pregnant women were carried out in DodaLab and FilaBavi Health and Demographic Surveillance Sites (HDSS)...
Dentin matrix protein 1 (DMP1) is a member of the small integrin–binding ligand N-linked glycoprotein (SIBLING) family, a group of proteins initially described as mineralized extracellular matrices components. More recently, SIBLINGs have been implicated in several key steps of cancer progression, including angiogenesis. Although proangiogenic activities have been demonstrated for 2 SIBLINGs, t...
INTRODUCTION It has remained controversial if antipsychotic treatment is associated with increased or decreased mortality among patients with schizophrenia, and if there are any clinically meaningful differences between specific agents and routes of administration. METHODS We linked prospectively gathered nationwide register-based data during 2006-2013 to study all-cause mortality among all p...
BACKGROUND Exhaled nitric oxide (FeNO) is a biomarker of airway inflammation. In the nitric oxide (NO) synthesis pathway, nitric oxide synthases (encoded by NOS1, NOS2A, and NOS3) and arginases (encoded by ARG1 and ARG2) compete for L-arginine. Although FeNO levels are higher in children with asthma/allergy, influence of these conditions on the relationships between variations in these genes an...
INTRODUCTION One in six children who have been admitted to hospital with an injury develop persistent stress symptoms that put their development at risk. Parents play a crucial role in children's psychological recovery, however, it is unknown how specific parenting behaviours can help or hinder. We aim to describe the nature and quantity of parent-child communication after a child has been inju...
OBJECTIVES The present study examined the impact of cumulative trauma exposure on current posttraumatic stress disorder (PTSD) symptom severity in a nonclinical sample of adults in their 60s. The predictive utility of cumulative trauma exposure was compared to other known predictors of PTSD, including trauma severity, personality traits, social support, and event centrality. METHOD Community-...
