Evaluation of a tablet-based assessment tool for measuring cognition among children 4-6 years of age in Ghana.

Objectives: To investigate several basic psychometric properties, including construct, convergent and discriminant validity, of the tablet-based Rapid Assessment of Cognitive and Emotional Regulation (RACER) among children aged 4-6 years in Ghana.

Methods: We investigated whether RACER tasks administered to children in Ghana could successfully reproduce expected patterns of performance previously found in high-income countries on similar tasks assessing inhibitory control (e.g.

Epidemiology of arterial hypertension in Tunisia: Hammam Sousse Sahloul Heart Study (HSHS).

Introduction: Tunisia is experiencing a double burden of morbidity, characterized by the explosion of cardiovascular diseases and their risk factors including arterial Hypertension. The objective of this study, based on the HSHS cohort (Hammam Sousse Sahloul Heart Study), was to determine the prevalence of hypertension in the general population and to identify its predisposing factors.

Methods: HSHS is a cardiovascular health promotion initiative in the city of Hammam Sousse (Tunisia).

Brazil's Missing Infants: Zika Risk Changes Reproductive Behavior.

Zika virus epidemics have potential large-scale population effects. Controlled studies of mice and nonhuman primates indicate that Zika affects fecundity, raising concerns about miscarriage in human populations. In regions of Brazil, Zika risk peaked months before residents learned about the epidemic and its relation to congenital anomalies.

Detecting the Effects of Early-Life Exposures: Why Fecundity Matters.

Prenatal exposures have meaningful effects on health across the lifecourse. Innovations in causal inference have shed new light on these effects. Here, we motivate the importance of innovation in the characterization of fecundity, and prenatal selection in particular.

Minds Under Siege: Cognitive Signatures of Poverty and Trauma in Refugee and Non-Refugee Adolescents.

The impacts of war and displacement on executive function (EF)-what we might call the cognitive signatures of minds under siege-are little known. We surveyed a gender-balanced sample of 12- to 18-year-old Syrian refugees (n = 240) and Jordanian non-refugees (n = 210) living in Jordan. We examined the relative contributions of poverty, trauma exposure, posttraumatic stress, and insecurity to variance in inhibitory control and working memory.
