Gliomas are the most common type of malignant primary brain tumor and few risk factors have been linked to their development. Handedness has been associated with several pathologic neurological conditions such as schizophrenia, autism, and epilepsy, but few studies have evaluated a connection between handedness and risk of glioma. In this study, we examined the relationship between handedness and glioma risk in a large case-control study (1849 glioma cases and 1354 healthy controls) and a prospective cohort study (326,475 subjects with 375 incident gliomas)...

BACKGROUND: Starting in August 2015, there was an increase in the number of cases of neonatal microcephaly in Northeast Brazil. These findings were identified as being an epidemic of microcephaly related to Zika virus (ZIKV) infection. The present study aims to analyse the spatial distribution of microcephaly cases in Recife (2015-2016), which is in Northeast Brazil, and its association with the living conditions in this city. METHODS: This was an ecological study that used data from reported cases of microcephaly from the State Health Department of Pernambuco (August 2015 to July 2016)...

BACKGROUND: Evidence of an adverse influence of soil transmitted helminth (STH) infections on cognitive function and educational loss is equivocal. Prior meta-analyses have focused on randomized controlled trials only and have not sufficiently explored the potential for disparate influence of STH infection by cognitive domain. We re-examine the hypothesis that STH infection is associated with cognitive deficit and educational loss using data from all primary epidemiologic studies published between 1992 and 2016...

The relationship between genetic risk variants associated with glucose homeostasis and type 2 diabetes risk has yet to be fully explored in African American populations. We pooled data from 4 prospective studies including 4622 African Americans to assess whether β-cell dysfunction (BCD) and/or insulin resistance (IR) genetic variants were associated with increased type 2 diabetes risk. The BCD genetic risk score (GRS) and combined BCD/IR GRS were significantly associated with increased type 2 diabetes risk...

The unified neutral theory of biodiversity and biogeography has gained the status of a quantitative null model for explaining patterns in ecological (meta)communities. The theory assumes that individuals of trophically similar species are functionally equivalent. We empirically evaluate the relative contribution of neutral and deterministic processes in shaping fruit-feeding butterfly assemblages in three tropical forests in Africa, using both direct (confronting the neutral model with species abundance data) and indirect approaches (testing the predictions of neutral theory using data other than species abundance distributions)...

Macrofauna is known to inhabit the top few 10s cm of marine sediments, with rare burrows up to two metres below the seabed. Here, we provide evidence from deep-water Permian strata for a previously unrecognised habitat up to at least 8 metres below the sediment-water interface. Infaunal organisms exploited networks of forcibly injected sand below the seabed, forming living traces and reworking sediment. This is the first record that shows sediment injections are responsible for hosting macrofaunal life metres below the contemporaneous seabed...

BACKGROUND: We investigated developmental changes in shortening of pro-saccade reaction time while maintaining neck flexion. METHODS: Subjects comprised 135 children (3-14 years) and 29 young adults (19-23 years). Children were divided into six groups in 2-year age strata. Pro-saccade reaction tasks for 30 s were performed in neck rest and flexion positions. Reaction times under each position were averaged in every 10-s period. RESULTS: Under neck rest position, reaction time in the 0-10 s period was significantly longer in the 3- to 4-year-old group than in the 5- to 6-year-old group and above...

Self-ratings of health (SRH) indicate current health-related quality of life and independently predict mortality. Studies show the SRH of older adults appears less influenced by physical health than the SRH of younger adults. But if physical health accounts less for the SRH of older adults, what factors take its place? To understand the relative contributions of social, emotional, and physical states to SRH by age, we analyzed data from the National Health Interview Survey 2006 to 2011 ( N = 153,341). In age-stratified regressions, physical health and functional limitations declined as correlates of SRH for older age strata, while social factors, such as gender and race, increased in importance...

PURPOSE: Racial differences in socioeconomic status (SES) explain some, but not all, of racial disparities in cardiovascular disease (CVD) risk. To address this, race disparities among higher SES individuals need to be assessed. The purpose of this study was to assess whether racial disparities in CVD risk factors differ by SES levels. METHODS: Data from the National Health and Nutritional Examination Survey 2007-2014 were used to calculate racial differences in hypertension, high cholesterol, diabetes, and obesity...

BACKGROUND: Ségou Region in Central Mali is an area of high malaria burden with seasonal transmission, high access to and use of long-lasting insecticidal nets (LLINs), and resistance to pyrethroids and DDT well documented in Anopheles gambiae s.l. (the principal vector of malaria in Mali). Ségou has recently received indoor residual spraying (IRS) supported by Mali's collaboration with the US President's Malaria Initiative/Africa Indoor Residual Spraying programme. From 2012 to 2015, two different non-pyrethroid insecticides: bendiocarb in 2012 and 2013 and pirimiphos-methyl in 2014 and 2015, were used for IRS in two districts...

BACKGROUND: The influence of the type of institutional setting on cesarean delivery is well documented. However, the traditional boundaries between public and private providers have become increasingly blurred with the commercialization of the state health sector that allows providers to tailor the quantity and quality of care according to patients' ability to pay. This study examined wealth-related variations in cesarean rates in six lower- and upper-middle income countries: the Dominican Republic, Egypt, Guatemala, Jordan, Pakistan, and the Philippines...

BACKGROUND: A recent report described a new PCOS-like phenotype in lean older infertile women, and was characterized by high age-specific anti-Müllerian hormone (AMH) but hypo- rather than the expected hyper-androgenism. The hypo-androgenism was, furthermore, characterized of, likely, adrenal origin and autoimmune etiology. PATIENTS AND METHODS: We extracted data on 708 consecutive infertility patients, and separated them into three age-strata, <35, 36-42, and >42 years...

BACKGROUND: There is extensive evidence that pre-pregnancy chronic hypertension is associated with high risk of development of severe hypertension and preeclampsia and birth of small for gestational age neonates. However, previous studies have not reported whether anti-hypertensive use, blood pressure control or normalization of blood pressure during early pregnancy influence the rates of these pregnancy complications. OBJECTIVE: To stratify women with pre-pregnancy chronic hypertension according to the use of antihypertensive medications and level of blood pressure control at the first hospital visit during the first-trimester of pregnancy and examine the rates of severe hypertension, preeclampsia and birth of small for gestational age neonates according to such stratification...

AIM: To improve the knowledge on characteristics, treatment and prognosis in patients with heart failure (HF) and mid-range ejection fraction discharged after an acute HF episode. METHODS: We prospectively included and followed 2753 patients admitted with HF to Internal Medicine units. Patients were classified according to ejection fraction (EF) into three strata: reduced, EF <40% (HFrEF); mid-range EF 40-49% (HFmrEF); and preserved EF ≥50% (HFpEF). Clinical, echocardiographic, laboratory data and treatment at discharge were recorded and the groups were compared...
