Prevalence of Substance Use and Its Association with Sociodemographic and Behavioral Factors among Women Who Conduct Sex Work in Kenya.

Female sex workers (FSWs) in sub-Saharan Africa are a marginalized group with an increased morbidity risk. Psychoactive substance use among this group is common and increases the risk of adverse health consequences. The type of substance used, extent, and nature of use varies with different settings and regions.

Prevalence of parental bereavement among female sex workers (FSW) in Kibra, Kenya.

Female sex workers (FSW) residing in Kibra, Kenya experience elevated exposure to adverse events, yet the prevalence of parental bereavement is not well characterized. This cross-sectional pilot study on 301 FSWs residing in Kibra, Kenya found that 67.7% of these women were parentally bereaved.

A phase 3 trial of RTS,S/AS01 malaria vaccine in African infants.

Background: The candidate malaria vaccine RTS,S/AS01 reduced episodes of both clinical and severe malaria in children 5 to 17 months of age by approximately 50% in an ongoing phase 3 trial. We studied infants 6 to 12 weeks of age recruited for the same trial.

Methods: We administered RTS,S/AS01 or a comparator vaccine to 6537 infants who were 6 to 12 weeks of age at the time of the first vaccination in conjunction with Expanded Program on Immunization (EPI) vaccines in a three-dose monthly schedule.

First results of phase 3 trial of RTS,S/AS01 malaria vaccine in African children.

Background: An ongoing phase 3 study of the efficacy, safety, and immunogenicity of candidate malaria vaccine RTS,S/AS01 is being conducted in seven African countries.

Methods: From March 2009 through January 2011, we enrolled 15,460 children in two age categories--6 to 12 weeks of age and 5 to 17 months of age--for vaccination with either RTS,S/AS01 or a non-malaria comparator vaccine. The primary end point of the analysis was vaccine efficacy against clinical malaria during the 12 months after vaccination in the first 6000 children 5 to 17 months of age at enrollment who received all three doses of vaccine according to protocol.

Safety, acceptability, and tolerability of 3 topical microbicides among heterosexual Kenyan men.

Objectives: To compare the acceptability, tolerability, and safety of 3 topical microbicide formulations (62% ethyl alcohol in emollient gel and 0.1% and 0.4% benzalkonium chloride on a sanitary wipe) for use on male genitalia.

Genomic organization and fine mapping of the keratin 2e gene (KRT2E): K2e V1 domain polymorphism and novel mutations in ichthyosis bullosa of Siemens.

We and others have previously shown that ichthyosis bullosa of Siemens, an autosomal dominant disorder characterized by epidermal thickening and blistering, is caused by mutations in the late-differentiation keratin K2e. Here, we have determined the genomic organization and complete sequence of the KRT2E gene, which consists of nine exons, spanning 7634 bp of DNA. The gene was mapped by high-resolution radiation-hybrid mapping to the interval between microsatellite markers D12S368 and CHLC.

Utility of deeper sections and special stains for dermatopathology specimens.

Special (non-hematoxylin and eosin) stains and deeper sections are routinely used in dermathopathology, although their utility has not been well established. All cases requiring special stains or deeper sections over a three-month period were reviewed to see how often these additional studies contributed to accurate diagnosis. In our series, deeper sections provided diagnostic information to the pathologist in 37.
