Feeding Expressed Breast Milk Alters the Microbial Network of Breast Milk and Increases Breast Milk Microbiome Diversity over Time.

Breastfeeding supplies nutrition, immunity, and hormonal cues to infants. Feeding expressed breast milk may result in de-phased milk production and feeding times, which distort the real-time circadian cues carried by breast milk. We hypothesized that providing expressed breast milk alters the microbiotas of both breast milk and the infant's gut.

Identification of the subventricular tegmental nucleus as brainstem reward center.

Rewards are essential for motivation, decision-making, memory, and mental health. We identified the subventricular tegmental nucleus (SVTg) as a brainstem reward center. In mice, reward and its prediction activate the SVTg, and SVTg stimulation leads to place preference, reduced anxiety, and accumbal dopamine release.

Gestational exposure to PM, NO, and sex steroid hormones: Identifying critical windows of exposure in the Rochester UPSIDE Cohort.

Background: Sex steroid hormones are critical for maintaining pregnancy and optimal fetal development. Air pollutants are potential endocrine disruptors that may disturb sex steroidogenesis during pregnancy, potentially leading to adverse health outcomes.

Methods: In the Environmental influences on Child Health Outcomes Understanding Pregnancy Signals and Infant Development pregnancy cohort (Rochester, NY), sex steroid concentrations were collected at study visits in early-, mid-, and late-pregnancy in 299 participants.

Post-Degradation Recovery of CsPbI Quantum Dot Solar Cells.

The stability of perovskite quantum dot solar cells is one of the key challenges of this technology. This study reveals the unique degradation behavior of cesium lead triiodide (CsPbI) quantum dot solar cells. For the first time, it is shown that the oxygen-induced degradation and performance loss of CsPbI quantum dot photovoltaic devices can be reversed by exposing the degraded samples to humidity, allowing the performance to recover and even surpass the initial performance.

Nurse Experiences in an Electronic Health Record Transition: A Mixed Methods Analysis.

Transitions from one EHR to another can be enormously disruptive to care. Nurses are the largest group of EHR users, but nurse experiences with EHR transitions have not been well documented. We sought to understand nurse experiences with an EHR transition at the US Department of Veterans Affairs.
