BACKGROUND In endemic areas, Rift Valley fever virus (RVFV) is a significant threat to both human and animal health. Goals of this study were to measure human anti-RVFV seroprevalence in a high-risk area following the 2006-2007 Kenyan Rift Valley Fever (RVF) epidemic, to identify risk factors for interval seroconversion, and to monitor individuals(More)
PURPOSE This study evaluated factors affecting reading performance in a sample (N = 544) of older adults (mean age 72.8 years, range 58 to 102) with good high-contrast acuity (> or = 20/32). METHODS Using the Pepper Reading Test, the relationship between reading rate and several vision measures was assessed. RESULTS Mean corrected reading rate fell(More)
Can vision tests predict subsequent loss of acuity? The association between performance on several low contrast spatial vision measures, glare recovery, color discrimination, flicker sensitivity, stereopsis and ocular disease status at baseline and acuity loss 4.4 years later was examined in a large aged random sample with good initial acuity. In univariate(More)
Introduction. We analyzed a database of 320 pediatric patients with acute lung injury (ALI), to test the hypothesis that positive fluid balance is associated with worse clinical outcomes in children with ALI. Methods. This is a post-hoc analysis of previously collected data. Cumulative fluid balance was analyzed in ml per kilogram per day for the first 72(More)
The research team recruited eight Chinese American (seven females, one male) lay health workers (LHWs). They received 12 h of training about colorectal cancer (CRC), its screening, and basic health education techniques. Each LHW were asked to recruit ten participants and conduct two educational sessions. Of the 81 participants recruited, 73 had not received(More)
BACKGROUND Parasitic infections, which are among the most common infections worldwide, disproportionately affect children; however, little is known about the impact of parasitic disease on growth in very early childhood. Our objective was to document the prevalence of parasitic infections and examine their association with growth during the first three(More)
BACKGROUND There are few population-based studies of cardiovascular risk factors, knowledge, and related behaviors among Vietnamese Americans. OBJECTIVE To describe cardiovascular risk factors, knowledge, and related behaviors among Vietnamese Americans and compare the results to non-Hispanic whites. DESIGN Comparison of data from two population-based,(More)
Characteristic cardiac valve abnormalities and left ventricular hypertrophy are present in untreated patients with mucopolysaccharidosis type VI (MPS VI). Cardiac ultrasound was performed to investigate these findings in subjects during long-term enzyme replacement therapy (ERT) with recombinant human arylsulfatase B (rhASB, rhN-acetylgalactosamine(More)
OBJECTIVE To compare the effectiveness of two different pharmacy-based colorectal cancer screening (CRCS) interventions taking place during an annual influenza vaccination campaign. DESIGN Time-randomized clinical trial. SETTING San Francisco, CA, in late 2008. PARTICIPANTS 133 adults aged 50 to 80 years visiting a pharmacy during an influenza(More)
BACKGROUND Mosquito-borne Rift Valley fever virus (RVFV) causes acute, often severe, disease in livestock and humans. To determine the exposure factors and range of symptoms associated with human RVF, we performed a population-based cross-sectional survey in six villages across a 40 km transect in northeastern Kenya.
