Shellfish harvesting in intertidal areas is a widespread and economically important activity in many countries across West Africa. However, in some areas, there is virtually no information concerning the levels of contaminants (and other elements related to nutritional aspects) in the harvested species. We collected sediments and several individuals of the West African bloody cockle Senilia senilis and of the razor clam Tagelus adansoni during the dry season of 2015 nearby three islands in the Bijagós archipelago, Guinea-Bissau...

The Ebola virus disease outbreak that began in Western Africa in December 2013 was unprecedented in both scope and spread, and the global response was slower and less coherent than was optimal given the scale and pace of the epidemic. Past experience with limited localized outbreaks, lack of licensed medical countermeasures, reluctance by first responders to direct scarce resources to clinical research, community resistance to outside interventions, and lack of local infrastructure were among the factors delaying clinical research during the outbreak...

Apolipoprotein L1 (ApoL1) is a human serum protein conferring resistance to African trypanosomes, and certain ApoL1 variants increase susceptibility to some progressive kidney diseases. ApoL1 has been hypothesized to function like a pore-forming colicin and been reported to have permeability effects on both intracellular and plasma membranes. Here, to gain insight into how ApoL1 may function in vivo, we used vesicle-based ion-permeability, direct membrane-association, and intrinsic fluorescence to study the activities of purified recombinant ApoL1...

BACKGROUND: Recent studies have described the entity of heart failure with recovered ejection fraction (HFrecEF), but population specific studies remain lacking. The aim of this study was to characterize patients enrolled in the African-American Heart Failure Trial (A-HeFT) who had significant improvement in their ejection fraction (EF) during the first 6 months of follow-up. METHODS AND RESULTS: Subjects (n = 59) with HFrecEF (improvement in EF from < 35% to > 40% in 6 months) were compared to 259 with heart failure and persistently reduced EF (HFrEF), defined as EF ≤ 40% at 6 month follow-up...

INTRODUCTION: Preventable hospitalizations (PHs) for chronic conditions could have been avoided if treated with primary healthcare. PH rates are higher among African Americans, and in areas with less healthcare. Little is known about the effects of non-healthcare local health-promoting resources (LHPRs). The objective of this study is to determine associations between LHPRs and chronic PH rates in Maryland, and to assess spatial clustering of areas with high PH rates. METHODS: Hospitalizations in 2010 were obtained from the Maryland Health Services Cost Review Commission by zip code of residence...

Protozoan parasites of the Trypanosomatidae family can cause devastating diseases in humans and animals, such as Human African Trypanosomiasis or Sleeping Sickness, Chagas disease and Leishmaniasis. Currently, there are molecular assays for detecting parasitic infections and their post-treatment monitoring based on nucleic acid amplification, but there are still certain limitations which limit the development of assays that can detect and discriminate between parasite infections with a single test. Here, we present the development of a novel molecular assay for the rapid identification of Trypanosomatids, integrating DNA analysis by dynamic chemistry in conjunction with Matrix-Assisted Laser Desorption Ionization - Time-of-Flight Mass Spectrometry (MALDI-ToF)...

BACKGROUND: Racism and discrimination are psychosocial stressors that affect the health of minority populations. While discrimination has been associated with poor mental health, little is known about the relationship between discrimination and mental health outcomes in youth nationally. Furthermore, mental and behavioral health consequences of discrimination may differ in different minority groups. OBJECTIVE: The goal of this study is to determine (1) how common perceptions of discrimination are in a nationally representative sample of African-American (AA) and Afro-Caribbean (AC) teens, (2) the relationship between discrimination and mental health conditions, and (3) whether discrimination has different associations with mental health in AA and AC youth...

A population structure study was performed in South African ovine populations using the OvineSNP50 beadchip. Blood samples were obtained from 295 sheep of which 172 had been identified as smallholder Dorpers, 4 smallholder White Dorpers, 46 purebred Dorpers, 26 purebred South African Mutton Merinos and 47 purebred Namaqua Afrikaners. Blood from the latter three breeds were obtained from a resource flock maintained on the Nortier research farm. Genetic diversity was estimated using allelic richness (A r), observed heterozygosity (H o), expected heterozygosity (H e) and inbreeding coefficient (F)...

The African grass Andropogon gayanus Kunth. is invading Australian savannas, altering their ecological and biogeochemical function. To assess impacts on nitrogen (N) cycling, we quantified litter decomposition and N dynamics of grass litter in native grass and A. gayanus invaded savanna using destructive in situ grass litter harvests and litterbag incubations (soil surface and aerial position). Only 30% of the A. gayanus in situ litter decomposed, compared to 61% of the native grass litter, due to the former being largely comprised of highly resistant A...

OBJECTIVE: The etiology of knee osteoarthritis (OA), the most common form of arthritis, is complex and may differ by race or ethnicity. In recent years, genetic studies have identified many genetic variants associated with OA, but nearly all the studies were conducted in European whites and Asian Americans. Few studies have focused on the genetics of knee OA in African Americans. METHODS: We performed a genome-wide association study of radiographic knee OA in 1217 African Americans from 2 North American cohort studies: 590 subjects from the Johnston County Osteoarthritis Project and 627 subjects from the Osteoarthritis Initiative...

Race is an important perceptual cue for face perception. In adults, other-race faces are elaborated differently and remembered less well than own-race faces. Moreover, they show a different pattern of activation at the neural level. Developmental studies demonstrated that, during the first year of life, infants start to show the same behavioral pattern as adults in race perception. However, little is known about where and how in the brain other-race perception is elaborated in this population. The present study is the first to investigate the development of different neural responses to faces of different race in infants using functional near-infrared spectroscopy (fNIRS)...

We report a case of severe type I hyperlipoproteinemia caused by autoimmunity against lipoprotein lipase (LPL) in the context of presymptomatic Sjögren's syndrome. A 7-year-old mixed race (Caucasian/African American) girl was admitted to the intensive care unit at Vanderbilt Children's Hospital with acute pancreatitis and shock. She was previously healthy aside from asthma and history of Hashimoto's thyroiditis. Admission triglycerides (TGs) were 2191 mg/dL but returned to normal during the hospital stay and in the absence of food intake...

BACKGROUND: The UN's Sustainable Development Goals (SDGs) are grounded in the global ambition of "leaving no one behind". Understanding today's gains and gaps for the health-related SDGs is essential for decision makers as they aim to improve the health of populations. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016), we measured 37 of the 50 health-related SDG indicators over the period 1990-2016 for 188 countries, and then on the basis of these past trends, we projected indicators to 2030...

African swine fever virus (ASFV) causes a highly lethal disease in swine for which neither a vaccine nor treatment are available. Recently, a new class of drugs that inhibit histone deacetylases enzymes (HDACs) has received an increasing interest as antiviral agents. Considering studies by others showing that valproic acid, an HDAC inhibitor (HDACi), blocks the replication of enveloped viruses and that ASFV regulates the epigenetic status of the host cell by promoting heterochromatinization and recruitment of class I HDACs to viral cytoplasmic factories, the antiviral activity of four HDACi against ASFV was evaluated in this study...

Epidemiological studies have shown the adverse neuro-behavioral health effects of lead exposure among children, in particular. However, there is lack evidence in this regard from developing countries. The main aim of this study was to assess the association between blood lead levels (BLLs) during early adolescence and violent behavior in late adolescence. Our study sample from the Birth to Twenty Plus cohort in Soweto-Johannesburg, South Africa included 1332 study participants (684 females). BLLs were measured using blood samples collected at age 13years...
