The large surface area of Lake Victoria (about 68,800 km(2)) makes it vulnerable to high atmospheric deposition of chemical pollutants. We present measurements of polychlorinated biphenyls (PCBs) from the lake's atmospheric environment. High volume air (24 h) samples were collected within the northern Lake Victoria watershed in Uganda over two periods; 1999-2004 [at Kakira (KAK) and Entebbe (EBB)] and 2008-2010 (at EBB only). Precipitation samples were also collected monthly during the 2008-2010 period at EBB...

OBJECTIVE: The purpose of this study was to examine the association between young men's perceived experiences with discrimination, both general and following the 2016 presidential election, and their loss of control (LOC) eating. The degree to which men identified with their ethnic identity was evaluated as a moderator. METHOD: The sample included 798 men (18-30 years; M = 24.0 ± 3.6) who identified as African American (n = 261), Asian/Asian American (n = 266), or Hispanic/Latino (n = 271)...

Despite good progress towards elimination, malaria continues to contribute substantially to the sub-Saharan African disease burden. Sustaining previous gains requires continued readiness to deliver malaria services in response to actual disease burden, which in turn contributes to health systems strengthening. This study investigates a health system innovation. We examined whether malaria prevalence, or endemicity, is a driver of health facility readiness to deliver malaria services. To estimate this association, we geo-linked cross-sectional facility survey data to endemicity data for Kenya, Namibia and Senegal...

Although the number of direct Ebola-related deaths from the 2013 to 2016 West African Ebola outbreak has been quantified, the number of indirect deaths, resulting from decreased utilization of routine health services, remains unknown. Such information is a key ingredient of health system resilience, essential for adequate allocation of resources to both 'crisis response activities' and 'core functions'. Taking stock of indirect deaths may also help the concept of health system resilience achieve political traction over the traditional approach of disease-specific surveillance...

Health-system responsiveness (HSR) measures the experience of health-system users in terms of the non-clinical aspects of the health system. This has been operationalized as a measurable construct in multiple surveys and studies. According to the literature, reporting behaviour may vary systematically across socio-demographic characteristics. In this study we explore the association between education levels and reporting behaviour in terms of HSR in South Africa using data from the World Health Organization Study on Global Ageing and Adult Health for South Africa (WHO SAGE) conducted in 2007 and 2008...

The association between cigarette smoking and inflammation is well known. However, the biological mechanisms behind the association are not fully understood, particularly the role of DNA methylation, which is known to be affected by smoking. Using 2-step epigenetic Mendelian randomization, we investigated the role of DNA methylation in the association between cigarette smoking and inflammation. In 822 African Americans from the Genetic Epidemiology Network of Arteriopathy, phase 2 (Jackson, Mississippi; 2000-2005), study population, we examined the association of cigarette smoking with DNA methylation using single nucleotide polymorphisms identified in previous genome-wide association studies of cigarette smoking...

Adolescents who experience social anxiety tend to hold fears about negative evaluations (e.g., taunting) and may also hold fears about positive evaluations (e.g., praise from a teacher). The Brief Fear of Negative Evaluation (BFNE) scale and Fear of Positive Evaluation Scale (FPES) are 2 widely used measures of adults' evaluative concerns. Yet we know little about their psychometric properties when assessing adolescents. In a mixed clinical/community sample of 96 adolescents (66.7% female; M = 14.50 years, SD = 0...

The knowledge, attitudes, and practices surrounding bushmeat consumption and importation in the United States are not well described. Focus groups of West African persons living in Minnesota, USA, found that perceived risks are low and unlikely to deter consumers. Incentives for importation and consumption were multifactorial in this community.

The human pegivirus (HPgV)-formerly GB virus C-has a beneficial impact on HIV disease progression that has been described in multiple studies. Given the high prevalence of HIV in sub-Saharan Africa and the continuing need to suppress HIV replication, this review provides a comprehensive overview of the existing data on HPgV infection in sub-Saharan Africa, with a particular focus on studies of prevalence and the circulating HPgV genotypes. This review also highlights the need for additional studies of HPgV conducted on the African continent and proposes a research agenda for evaluation of HPgV...

Assessment of global endocranial morphology and regional neuroanatomical changes in early hominins is critical for the reconstruction of evolutionary trajectories of cerebral regions in the human lineage. Early evidence of cortical reorganization in specific local areas (e.g. visual cortex, inferior frontal gyrus) is perceptible in the non-human South African hominin fossil record. However, to date, little information is available regarding potential global changes in the early hominin brain. The introduction of non-invasive imaging techniques opens up new perspectives for the study of hominin brain evolution...

The increasing migration of people from their homeland in far distant regions to Europe in the last few years has strongly influenced the rise of previously rarely seen diseases. They not only originate from the respective homeland but also from the transit countries during the migration process. We report the case of a 27-year-old male migrant from Eritrea, who after months of flight as a refugee travelling through various African countries, presented at our hospital with a progressive, painful radiculopathy...

Understanding human mating patterns, which can affect population genetic structure, is important for correctly modeling populations and performing genetic association studies. Prior studies of assortative mating in humans focused on trait similarity among spouses and relatives via phenotypic correlations. Limited research has quantified the genetic consequences of assortative mating. The degree to which the non-random mating influences genetic architecture remains unclear. Here, we studied genetic variants associated with human height to assess the degree of height-related assortative mating in European-American and African-American populations...

Background -Despite concerns about adverse neurocognitive events raised by prior trials, pharmacologic PCSK9 inhibition was not associated with neurocognitive effects in a recent phase 3 randomized trial. PCSK9 loss-of-function (LOF) variants that result in life-long exposure to low LDL-C can provide information on the potential long-term effects of low LDL-C on neurocognitive impairment and decline. Methods -We investigated the association between PCSK9 LOF variants and neurocognitive impairment and decline among African-American REasons for Geographic and Racial Differences in Stroke (REGARDS) study participants with (n=241) and without (n=10,454) C697X or Y142X LOF variants...

This study investigated peer-perceived social/reputational correlates of patterns of aggression, victimization, and prosocial behavior. Participants were a predominantly African-American (i.e., 87%) sample of 320 fourth and fifth graders (45% male, Mean age=10.4years) attending six urban public elementary schools. Using latent profile analysis, profiles of peer-perceived and teacher-perceived aggressive, victimized, and prosocial youth were identified. These latent profiles were then compared on a range of peer-perceived social/reputational characteristics...

Teaching behaviors are associated with a range of student academic and mental health outcomes. Substantial academic, school disciplinary, and mental health disparities across African American and European American students suggest that diverse students may view and interpret teaching behaviors differently. The Teaching Behavior Questionnaire measures students' perceptions of teaching behaviors. The purpose of the current study was to examine the scale's factor structure among European American high school students using exploratory factor analysis and, subsequently, cross-validate using confirmatory factor analysis based on African American student data...

Within the existing health financing literature, males are typically categorized as the household's decision-makers. While this view accurately reflects many local sociocultural realities, approximately a quarter of sub-Saharan African households are now headed by females. In light of various efforts to expand health insurance coverage in the region, it is necessary to examine whether the factors influencing voluntary health insurance enrolment are analogous across male- and female-headed households. This study sought to identify the gendered determinants of voluntary enrolment into a church-run micro health insurance scheme...
