Appropriate use of antibiotics is life-saving in neonatal early-onset sepsis (EOS), but overuse associated with antimicrobial resistance and long-term adverse outcomes. Large international studies quantifying early-life antibiotic exposure along EOS incidence are needed to provide a basis for future interventions aimed at safely reducing exposure.To compare early postnatal antibiotics, EOS, mortality among different networks high-income countries.This retrospective, cross-sectional study...

It is increasingly recognized that psychological stress influences inflammatory responses and mood. Here, we investigated whether (combined acoustic restraint stress) activates the tryptophan (Trp) catabolizing enzyme indoleamine 2,3-dioxygenase 1(IDO1) thereby alters immune homeostasis behavior in mice. We measured IDO1 mRNA expression plasma levels of Trp catabolites after a single 2-h session repeatedly stressed (4.5-days stress, twice day) naïve BALB/c A role cytokines acute...

Stress is a powerful modulator of neuroendocrine, behavioral, and immunological functions. After 4.5-d repeated combined acoustic restraint stress as murine model chronic psychological stress, severe metabolic dysregulations became detectable in female BALB/c mice. Stress-induced alterations processes that were found hepatic mRNA expression profiling verified by vivo analyses. Repeatedly stressed mice developed hypermetabolic syndrome with the loss lean body mass, hyperglycemia,...

In preterm infants, natural variation of breast milk composition makes it difficult to achieve recommended macronutrient intakes with standard fortification. Evidence suggests that nutritional deficiency induces poor postnatal growth. This study investigates impacts target fortification on growth and metabolism by adjusting macronutrients.This was conducted as a single-centre, double-blind, randomized controlled trial for infants <30 gestational weeks. The control group received the...
