Sensitivity and Specificity of Suspected Case Definition Used during West Africa Ebola Epidemic.

Rapid early detection and control of Ebola virus disease (EVD) is contingent on accurate case definitions. Using an epidemic surveillance dataset from Guinea, we analyzed an EVD case definition developed by the World Health Organization (WHO) and used in Guinea. We used the surveillance dataset (March-October 2014; n = 2,847 persons) to identify patients who satisfied or did not satisfy case definition criteria.

Use of combined hormonal contraceptives among women with migraines and risk of ischemic stroke.

Background: Migraine with aura and combined hormonal contraceptives are independently associated with an increased risk of ischemic stroke. However, little is known about whether there are any joint effects of migraine and hormonal contraceptives on risk of stroke.

Objective: We sought to estimate the incidence of stroke in women of reproductive age and examine the association among combined hormonal contraceptive use, migraine type (with or without aura), and ischemic stroke.

We assessed current permanent and reversible prescription contraceptive use during October 1, 2010, to September 30, 2011, with diagnosis, procedure, and pharmacy codes and calculated prevalence by age and condition.

Childhood chronic health conditions and educational attainment: a social ecological approach.

Purpose: This study examined the association between types of chronic health conditions reported during childhood and adolescence and their impact on educational attainment. School and neighborhood environments and potential mediating factors from academic and psychosocial variables were investigated.

Methods: Using the National Longitudinal Survey of Youth-Cohort 1997, multivariate logistic regression models were fit to estimate the association between chronic health conditions and educational attainment, adjusting for confounders.
