Risk of Pre-Eclampsia in First and Subsequent Pregnancies: Prospective Cohort Study
(BMJ Publishing Group, 2009)
Objective: To investigate whether pre-eclampsia is more common in first pregnancies solely because fewer affected women, who presumably have a higher risk of recurrence, go on to have subsequent pregnancies. Design: ...
Incident Tuberculosis among Recent US Immigrants and Exogenous Reinfection
(Centers for Disease Control and Prevention, 2005)
Mathematical models and molecular epidemiologic investigation support the argument that exogenous reinfection plays an important role in tuberculosis transmission in high-incidence regions. We offer additional data from ...
PBAT: A comprehensive software package for genome-wide association analysis of complex family-based studies
(BioMed Central, 2005)
The PBAT software package (v2.5) provides a unique set of tools for complex family-based association analysis at a genome-wide level. PBAT can handle nuclear families with missing parental genotypes, extended pedigrees ...
Trends in nicotine yield in smoke and its relationship with design characteristics among popular U.S. cigarette brands, 1997-2005
(BMJ Publishing Group, 2007)
Objectives: To determine whether nicotine yields in the smoke of cigarettes would show an overall increase over time or an increasing trend limited to any particular market category (eg, full flavour vs light, medium (mild) ...
Trends in the Use of Cigarettes and Other Tobacco Products, 2000-2007
(American Medical Association (AMA), 2008)
Recommendations for using standardised phenotypes in genetic association studies
(BioMed Central, 2009)
Genetic association studies of complex traits often rely on standardised quantitative phenotypes, such as percentage of predicted forced expiratory volume and body mass index to measure an underlying trait of interest (eg ...
Sex Disparities in the Treatment and Control of Cardiovascular Risk Factors in Type 2 Diabetes
(American Diabetes Association, 2008)
OBJECTIVE—To assess whether sex differences exist in the effective control and medication treatment intensity of cardiovascular disease (CVD) risk factors. RESEARCH DESIGN AND METHODS—We performed a cross-sectional analysis ...
Association Between the Plasma/Whole Blood Lead Ratio and History of Spontaneous Abortion: A Nested Cross-Sectional Study
(BioMed Central, 2007)
Background: Blood lead has been associated with an elevated risk of miscarriage. The plasmatic fraction of lead represents the toxicologically active fraction of lead. Women with a tendency to have a higher plasma/whole ...
Increased Risk of Paroxysmal Atrial Fibrillation Episodes Associated with Acute Increases in Ambient Air Pollution
(National Institute of Environmental Health Sciences, 2006)
Objectives: We reported previously that 24-hr moving average ambient air pollution concentrations were positively associated with ventricular arrhythmias detected by implantable cardioverter defibrillators (ICDs). ICDs ...
Influenza and Ultraviolet Germicidal Irradiation
