OBJECTIVE: To evaluate the association between severity of prior low birth weight (LBW) delivery and adverse perinatal outcomes in the subsequent delivery among an HIV-prevalent urban African population. METHODS: A retrospective cohort study was conducted among 41 109 women who had undergone two deliveries in Lusaka, Zambia, between February 1, 2006, and May 31, 2013. The relationship between prior LBW delivery (<2500 g) and a composite measure of adverse perinatal outcome in the second pregnancy was assessed using multivariate logistic regression...

OBJECTIVE: To measure key obstetric and neonatal outcomes recorded at a tertiary hospital in Zambia over a 5-year period. METHODS: A retrospective analysis was conducted among women who had delivered at the University Teaching Hospital in Lusaka, between January 1, 2008, and December 31, 2012. Data were extracted from electronic medical records. The main outcomes were maternal mortality, cesarean delivery, prenatal or intrapartum hemorrhage, stillbirth, a 5-minute Apgar score of less than 7, and admission to the neonatal intensive care unit...

OBJECTIVES: Patient frailty is increasingly recognised as contributing to adverse postoperative outcomes in cardiothoracic surgery. The goal of this review is to evaluate the predictive ability of frailty scoring systems and their limitations in risk assessment of patients undergoing cardiac surgery. METHODS: Frailty studies were identified by searching electronic databases. Studies in which the measuring instrument was defined as a multidimensional tool focusing on a population undergoing cardiac operations were included...

OBJECTIVE: To perform a repeatable idealized in vitro model to evaluate the effects of key design features and integrated screw fixation on unloaded surface engagement, subsidence, and torsional stability. METHODS: We evaluated four different stand-alone anterior lumbar interbody fusion (ALIF) cages with two, three, and four screw designs. Polyurethane (saw-bone) foam blocks were used to simulate the vertebral bone. Fuji Film was used to measure the contact footprint, average pressure, and load generated by fixating the cages with screws...

BACKGROUND: In the United States, there is racial/ethnic disparity in the care of rheumatoid arthritis (RA), yet there are limited data regarding the impact of varied health care systems on treatment outcomes. OBJECTIVE: The aim fo this study was to compare the frequencies of use of disease-modifying antirheumatic drugs and biologic agents in racial minorities with RA in a single-payer and variable-access health systems. METHODS: Rheumatoid arthritis disease status was examined in the Ethnic Minority Rheumatoid Arthritis Consortium (EMRAC) and Veterans Affairs Rheumatoid Arthritis Registry (VARA); frequencies of prednisone and disease-modifying antirheumatic drugs and biologic agent use at enrollment were documented...

Alcohol dependence is associated with deficits in glutamate uptake and impairment of glutamate homeostasis in different brain reward regions. Glutamate transporter subtype 1 (GLT-1), cystine-glutamate exchanger (xCT) and glutamate/aspartate transporter (GLAST) are one of the key players in regulating extracellular glutamate concentration in the brain. Parenteral treatment with ceftriaxone, β-lactam antibiotic, has been reported to attenuate ethanol consumption and reinstatement to cocaine-seeking behavior, in part, by restoring the expression of GLT-1 and xCT in mesocorticolimbic brain regions in rats...

OBJECTIVE: Because of concern over medical ionizing radiation exposure of children, contrast-enhanced ultrasound (CEUS) has generated interest as an inexpensive, ionizing radiation-free alternative to CT and MRI. CEUS has received approval for pediatric hepatic use but remains off-label for a range of other applications. The purposes of this study were to retrospectively analyze adverse incidents encountered in pediatric CEUS and to assess the financial benefits of reducing the number of CT and MRI examinations performed...

BACKGROUND:  The World Health Organization recommends that malaria treatment be based on demonstration of the infecting Plasmodium parasite specie. Malaria rapid diagnostic tests (RDTs) are recommended at community points of care because they are accurate and rapid. We report on parasitological results in a malaria study in selected rural communities in 3 African countries. METHODS:  In Nigeria, community health workers (CHWs) performed RDTs (SD-Bioline) and thick blood smears on all children suspected to have malaria...

BACKGROUND: -Thrombus aspiration during percutaneous coronary intervention (PCI) for the treatment of ST elevation myocardial infarction (STEMI) has been widely used; however, recent trials have questioned its value and safety. In this meta-analysis, we, the trial investigators, aimed to pool the individual patient data from these trials to determine the benefits and risks of thrombus aspiration during PCI in patients with STEMI. METHODS: -Included were large (N≥1000) randomized controlled trials comparing manual thrombectomy vs...

BACKGROUND: Effective policies to control hypertension require an understanding of its distribution in the population and the barriers people face along the pathway from detection through to treatment and control. One key factor is household wealth, which may enable or limit a household's ability to access health care services and adequately control such a chronic condition. This study aims to describe the scale and patterns of wealth-related inequalities in the awareness, treatment and control of hypertension in 21 countries using baseline data from the Prospective Urban and Rural Epidemiology study...

PURPOSE: Atrial fibrillation (AF) is the most common form of arrhythmia. AF leads to electrical remodelling and fibrosis of the atria; however, the mechanism(s) remain poorly understood. Galectin-3 is a potential mediator of cardiac fibrosis. The present study aimed to examine the relationship between serum galectin-3 levels and paroxysmal AF. METHODS: Forty-six patients with paroxysmal AF and preserved left ventricular systolic function, and 38 age- and gender-matched control subjects, were involved in the study...

BACKGROUND: Statin treatment and variants in the gene encoding HMG-CoA reductase are associated with reductions in both the concentration of LDL cholesterol and the risk of coronary heart disease, but also with modest hyperglycaemia, increased bodyweight, and modestly increased risk of type 2 diabetes, which in no way offsets their substantial benefits. We sought to investigate the associations of LDL cholesterol-lowering PCSK9 variants with type 2 diabetes and related biomarkers to gauge the likely effects of PCSK9 inhibitors on diabetes risk...

Exposure to ethanol (EtOH) or methamphetamine (MA) can lead to increase in extracellular glutamate concentration in the brain. Although studies from ours showed the effects of EtOH exposure on key glial glutamate transporters, little is known about the effects of sequential exposure to EtOH and MA or MA alone on certain glial glutamate transporters. In this study, we investigated the effects of sequential exposure to EtOH and MA on the expression of the major glutamate transporters, glutamate transporter 1 (GLT-1), as well as cystine/glutamate antiporter (xCT) and glutamate aspartate transporter (GLAST) in striatum and hippocampus...
