[Diphtheria-tetanus-pertussis vaccine mortality].

Although the diphtheria-tetanus-pertussis (DTP) vaccine is lifesaving through decades, it has been voiced that the vaccine is associated with 50% increase in mortality, an alleged negative non-specific vaccine effect prone to girls. Post hoc analyses of historical observational data supporting the hypothesis of the DTP vaccine having detrimental effects have never been replicated in low- or high-income countries. An RCT in Guinea-Bissau found fewer deaths with DTP vaccine than without.

Exercise during pregnancy modulates infant cellular and whole-body adiposity.

Non-pharmaceutical interventions are needed to target the growing intergenerational cycle of obesity. We aimed to determine whether in utero exposure to different exercise doses during pregnancy directly reduces infant cellular and whole-body adiposity. Pregnant women completed ~24 weeks of supervised exercise training; for standardization of exercise analysis (frequency, intensity, time, and volume-FIT-V), metrics were assessed from 16 to 36 weeks.

Exercise during pregnancy Dose: Influence on preterm birth outcomes.

Background: Preterm delivery typically increases health risk for neonates and is associated with longer infant hospital stay and financial burden. Prenatal exercise dose (frequency, intensity, type, time, volume) have been shown to influence birth outcomes. Increased prenatal exercise dose could therefore provide a critical reduction in health risk and financial burden in preterm neonates.
