OBJECTIVES To assess changes in HIV incidence and prevalence in Caió, a rural area of Guinea-Bissau, between 1990 and 2007. DESIGN Three cross-sectional community surveys. METHODS In 1990, 1997, and 2007, surveys were conducted among adults. The prevalence of HIV-1 and of HIV-2 was estimated for each survey, and incidence rates were calculated for the(More)
Multilevel analysis was used to identify individual and household level factors associated with malaria risk in 1,367 individuals in a peri-urban area of highland Ethiopia. Living within 450 m of a major vector-breeding site accounted for 38.78% and 78.49% of between-household variance in malaria incidence in adults and children, respectively. In adults,(More)
Cell types of lung epithelia of mini pigs have been studied using a panel of monoclonal and polyclonal antibodies against cytokeratins (CKs) and vimentin and three lectins before and after radiation-induced fibrosis. In normal tissues, CK18 specific antibodies reacted above all with type II alveolar epithelial cells, while CK7 and pan CK-specific antibodies(More)
A serologic survey has documented probable infection with reticuloendotheliosis (RE) virus in 21.0% of 101 layer flocks, 23.5% of 85 broiler and broiler-breeder flocks, 2.3% of 43 backyard chicken flocks, and 4.8% of 125 turkey production and breeder flocks. However, no infection was detected in 72 grandparent lines of chicken breeding stocks representing(More)
OBJECTIVES To determine the duration of protection from hepatitis B vaccine given in infancy and early childhood and asses risk factors for HBV infection and chronic infection. METHODS In 1984 infant HBV vaccination was started in two Gambian villages. Cross sectional serological surveys have been undertaken every 4 years to determine vaccine efficacy. In(More)
BACKGROUND The reservoir of Plasmodium infection in humans has traditionally been defined by blood slide positivity. This study was designed to characterize the local reservoir of infection in relation to the diverse var genes that encode the major surface antigen of Plasmodium falciparum blood stages and underlie the parasite's ability to establish chronic(More)
OBJECTIVES This study's objective was to assess outcomes in HIV-1 and HIV-2 infected antiretroviral therapy (ART)-naïve patients starting ART in the Gambia, West Africa. DESIGN A cohort design was used to estimate survival in ART patients and determine whether survival and time to virologic failure varied across patient subgroups. METHODS Mortality,(More)
Complementary medicine (CM) use is common among cancer patients. However, little is known about CM products that are utilised during radiotherapy and/or chemotherapy. Out of 62 cancer patients who completed a specialised survey, 35 (56%) consumed some type of CM during active anti-cancer therapy. Cancer patients reported the use of herbal teas (52%),(More)
We present a case of colonic histoplasmosis in a young HIV antibody-positive homosexual male who presented with acute diarrhea. The diagnosis was made by flexible sigmoidoscopy with biopsy which revealed organisms morphologically consistent with Histoplasma capsulatum, and was later confirmed by fungal culture of the biopsy specimens. At colonoscopy, skip(More)
BACKGROUND The 2011 Swaziland HIV Incidence Measurement Survey (SHIMS) was conducted as part of a national study to evaluate the scale up of key HIV prevention programs. METHODS From a randomly selected sample of all Swazi households, all women and men aged 18-49 were considered eligible, and all consenting adults were enrolled and received HIV testing(More)
