Sexually dimorphic behavioral and neural responses to a predator scent.

Male and female C57BL/6 J mice were tested on the predator odor response task, where they needed to cross through a chamber of scented bedding to reach a sucrose reward. Following the behavioral testing, mouse brains were immunohistochemically labeled for expression of the immediate early gene c-fos. In the presence of the novel odorant methyl valerate (MV), both males and females exhibited increased exploration behaviors and delayed rewards compared to control bedding.

A Pilot Study to Reduce Central Line-Associated Bloodstream Infections in Children From Extremely Low-Income Settings With Intestinal Failure-Meeting the Challenge.

Background: Central line-associated bloodstream infections (CLABSIs) are major sources of morbidity, death, and healthcare costs in patients who receive home parenteral nutrition (HPN). The majority of HPN-dependent children in southern Israel reside in poor communities with substandard living conditions, which creates significant challenges for the safe provision of HPN. We developed a pilot intervention that aimed to reduce the rates of CLABSI and central venous catheter (CVC) replacements in this vulnerable population in our region.
