The study population was representative of twins with multiple sclerosis. Twins from Canada and adjace...
BACKGROUND The objective of this study was to examine the epidemiology of syphilis among high-risk socially marginalized populations in urban, coastal Peru, to quantify the prevalence of recent syphilis infection and identify risk factors. METHODS Survey data and serologic specimens were collected from a population-based sample of 3 populations: men who have sex with only men (MSOM), socially...
BACKGROUND The effects of intermittent, high dose vitamin D treatment in older adults have not been documented. We conducted a meta-analysis to provide a quantitative assessment of the efficiency of intermittent, high dose vitamin D treatment on falls, fractures, and mortality among older adults.

BACKGROUND Databases of medical claims can be valuable resources for cardiovascular research, such as comparative effectiveness and pharmacovigilance studies of cardiovascular medications. However, claims data do not include all of the factors used for risk stratification in clinical care. We sought to develop claims-based algorithms to identify individuals at high estimated risk for coronary h...
To assess the annual risk for latent tuberculosis infection (LTBI) among health care workers (HCWs), the incidence rate ratio for tuberculosis (TB) among HCWs worldwide, and the population-attributable fraction of TB to exposure of HCWs in their work settings, we reviewed the literature. Stratified pooled estimates for the LTBI rate for countries with low (<50 cases/100,000 population), interme...
To assess the risk of prevalent high-grade cervical squamous intraepithelial lesions (HSILs) or invasive cervical cancer (ICC) associated with human immunodeficiency virus (HIV) type 1, HIV-2, and human papillomavirus (HPV) infections, HIV load, and CD4 cell count, we studied 4119 women attending an outpatient clinic in Senegal. HIV infection was associated with increased rates of cervical infe...
