The Ebola virus disease (EVD) epidemic, which began in West Africa in December 2013, claimed more than 11,000 lives, with more than 4,800 of these deaths occurring in Liberia. The epidemic had an additional effect of paralyzing the health-care systems in affected countries, which led to even greater mortality and morbidity. Little is known about the impact that the epidemic had on the provision of basic health care. During the period from March to May 2015, we undertook a nationwide, community-based survey to learn more about health-care access during the EVD epidemic in Liberia. A cluster sampling strategy was used to administer a structured in-person survey to heads of households located within the catchment areas surrounding all 21 government hospitals in Liberia. A total of 543 heads of household from all 15 counties in Liberia participated in the study; more than half (67%) of urban respondents and 46% of rural respondents stated that it was very difficult or impossible to access health care during the epidemic. In urban areas, only 20-30% of patients seeking care during the epidemic received care, and in rural areas, only 70-80% of those seeking care were able to access it. Patients requiring prenatal and obstetric care and emergency services had the most difficulty accessing care. The results of this survey support the observation that basic health care was extremely difficult to access during the EVD epidemic in Liberia. Our results underscore the critical need to support essential health-care services during humanitarian crises to minimize preventable morbidity and mortality.

Translational incorporation of the unusual amino acid selenocysteine in eukaryotes requires a coding region UGA codon (which otherwise serves as a termination signal), a selenocysteine insertion sequence (SECIS) in the 3-untranslated region of the mRNA, and selenocysteyl-tRNA. The mechanisms involved in SECIS recognition by the eukaryotic translational machinery remain unknown. We report the detection of RNA-binding proteins that specifically recognize the SECIS from human cellular glutathione peroxidase (GPX1) transcripts. RNA gel shift assays showed three retarded bands after incubation with COS-1 whole cell lysate or S-100 cytosol fraction or with extracts from hepatoma cell lines HepG2 and Hep3B. The specificity of the binding was demonstrated by competition by cold unlabeled SECIS RNA and by lack of competition by other RNA species with similar stem-loop secondary structures, such as the human immunodeficiency virus (HIV) transactivation-response region of HIV mRNA element, and mutated SECIS constructs. UV cross-linking and SDSpolyacrylamide gel electrophoresis revealed at least two proteins, with estimated molecular masses of 55,000 and 65,000 Da, that bind to the SECIS. Examination of a series of insertion and deletion SECIS mutants indicated recognition of the SECIS primarily through the basal stem region, although the upper stem, loop, and two of three short conserved sequences also appear to contribute to the affinity of the binding.A wide variety of sequence elements have recently been identified in the 5Ј-and 3Ј-untranslated regions (UTR) 1 of eukaryotic mRNAs. The resultant RNA secondary structures and the RNA-binding proteins that recognize them play important roles in the regulation of mRNA stability and translation (1-6).One such sequence is the selenocysteine insertion sequence (SECIS; also termed the selenium translation element) in the 3Ј-UTR of eukaryotic gene transcripts encoding selenoproteins (7-9). Members of this unique group of proteins contain one or more selenocysteine residues, often at their active sites, and several catalyze important oxidation/reduction reactions (10). The gene transcripts for these selenoproteins encode the atypical amino acid by a UGA codon, which normally functions as a termination signal (11,12). In eukaryotes, incorporation of selenocysteine into the polypeptide chain at this UGA codon requires the presence of at least one SECIS, located in the 3Ј-UTR as much as 1200 nucleotides downstream (8, 11). Comparison of the sequences of SECIS in rat and human iodothyronine deiodinase, cellular glutathione peroxidase, and selenoprotein P mRNAs (7, 8, 13) has revealed only three very short conserved sequences, but all share a common computer-predicted secondary structure featuring a long stem, several bulges, and an apical loop with three short conserved sequences. These characteristic features are illustrated in the diagram of the SECIS from the human cellular glutathione peroxidase (GPX1) gene transcript in Fig. 1A.We have shown that this SECIS is necessary for trans...

RAHI–SATHI presents an innovative twinning model of global health academic partnership, resulting in a number of successful research activities, that features trainees or students as the driving force, complemented by strategic institutional support from both sides of the partnership. Others can promote similar student-led initiatives by: (1) accepting an expanded role for trainees in global health programs, (2) creating structured research and program opportunities for trainees, (3) developing a network of faculty and trainees interested in global health, (4) sharing extramural global health funding opportunities with faculty and trainees, and (5) offering seed funding.

This article describes a model employed by the Academic Collaborative to Support Medical Education in Liberia to augment medical education in a postconflict setting where the health and educational structures and funding are very limited. We effectively utilized a cohort of visiting US pediatric faculty and trainees for short-term but recurrent clinical work and teaching. This model allows US academic medical centers, especially those with smaller residency programs, to provide global health experiences for faculty and trainees while contributing to the strengthening of medical education in the host country. Those involved can work toward a goal of sustainable training with a strengthened host country specialty education system. Partnerships such as ours evolve over time and succeed by meeting the needs of the host country, even during unanticipated challenges, such as the Ebola virus outbreak in West Africa.
