Transmission dynamics and control of Ebola virus disease outbreak in Nigeria, July to September 2014

We analyse up-to-date epidemiological data of the Ebola virus disease outbreak in Nigeria as of 1 October 2014 in order to estimate the case fatality rate, the proportion of healthcare workers infected and the transmission tree. We also model the impact of control interventions on the size of the epidemic. Results indicate that Nigeria’s quick and forceful implementation of control interventions was determinant in controlling the outbreak rapidly and avoiding a far worse scenario in this country.

Evaluation of Nigerian traditional medicines: II. Effects of some Nigerian folk remedies on peptic ulcer

Antiulcer activity of four medicinal plants, Diodia sarmentosa (whole plant), Cassia nigricans (leaves), Ficus exasperata (leaves) and Synclisia scabrida (leaves), which are commonly used by the Nigerian traditional healers for the treatment of peptic ulcer were investigated. Acute toxicity tests were also carried out. The results revealed that the four extracts possess significant anti-ulcerogenic properties in a dose-dependent way. They protected rats from aspirin-induced ulcerogenesis, delayed intestinal transit, increased the pH, and decreased both the volume and acidity of gastric secretion. These results correlate with local use of the plants.

Screening African rice (Oryza glaberrima) for tolerance to abiotic stresses: I. Fe toxicity

Iron (Fe) toxicity is recognized as one of the most widely spread soil constraints for rice production especially in West Africa. Oryza glaberrima the cultivated rice species that originated from West Africa is well-adapted to its growing ecologies. The aim of this study was to identify the promising O. glaberrima accessions tolerant to Fe toxicity from the 2106 accessions held at the AfricaRice gene bank. The screenings were conducted over a four-year period and involved evaluating the entries under Fe-toxic field conditions in West Africa, selecting good yielding accessions and repeating the testing with newly selected lines. Three accessions (TOG 7206, TOG 6218-B and TOG 7250-A) were higher yielding than O. sativa checks under stress but with similar yields under control conditions. These accessions yielded over 300 g/m² under both Fe toxicity and control conditions. In conclusion, these materials could be used as donors in breeding programs for developing high yielding rice varieties suited to Fe toxicity affected areas in West Africa.

The HIP LADIES: A Pilot Health Improvement Project for HIV Prevention in Black College Women

A disproportionate number of new HIV infections in the United States occur in Black women. We pilot-tested feasibility and acceptability of a manualized HIV prevention intervention developed with and for Black college women. We used a prospective, randomized 2-group design, with 3 data collection times. Participants included 18- to 24-year-old Black women (N = 65), who were enrolled at 2 southern universities; 46 completed pre- and post-assessments. We found that participants in the intervention arm had positive changes in HIV knowledge (p < .0001) and behavioral intentions (p = .039) outcomes. There were, however, no significant differences between intervention and control groups when considering motivational factors and behavioral skills that promoted HIV prevention: social norms, condom use self-efficacy, and assertive sexual communication. We found preliminary evidence of efficacy for an HIV prevention intervention tailored to Black college women. Researchers should partner with Black college women to develop and implement HIV prevention interventions.

Synchronous Bilateral Breast Cancer With Discordant Receptor Status: Treating One Patient but Two Diseases

The expression of hormone receptors (estrogen and progesterone) and human epidermal growth factor receptor-2 (HER2) has been used for both therapeutic and prognostic purposes in the management of breast cancer. The presence of a discordant receptor status complicates the approach to treatment in patients with synchronous bilateral breast cancer. We describe the case of a 45-year-old female with synchronous bilateral breast cancer with a triple-negative tumor and a contralateral HER2-positive tumor and discussed the impact of this on the approach to therapeutic management.
