Application of the market-ready NAVETTA electrodeposition chamber for controlled exposure with nano-scaled aerosols.

Exposure of lung epithelia to aerosols is omnipresent. Chronic exposure to polluted air is a significant factor in the development of pulmonary diseases, which are among the top global causes of death, including COVID-19, chronic obstructive pulmonary disease, lung cancer, and tuberculosis. As efforts to prevent and treat lung diseases increase, the development of pulmonary drug delivery systems has become a major area of interest.

Non-random mating behaviour between diverging littoral and pelagic three-spined sticklebacks in an invasive population from Upper Lake Constance.

Adaptive divergence and increased genetic differentiation among populations can lead to reproductive isolation. In Lake Constance, Germany, a population of invasive three-spined stickleback () is currently diverging into littoral and pelagic ecotypes, which both nest in the littoral zone. We hypothesized that assortative mating behaviour contributes to reproductive isolation between these ecotypes and performed a behavioural experiment in which females could choose between two nest-guarding males.

Neonatal circumcisions and parental refusal of intramuscular vitamin K: A review of the literature and current guidelines.

Introduction: Parental refusal of intramuscular (IM) vitamin K in newborns poses challenges, particularly for pediatric urologists assessing the safety of neonatal circumcision. Vitamin K deficiency bleeding (VKDB) is a known risk, with lack of prophylaxis increasing bleeding complications. This study evaluates the safety of neonatal circumcision without IM vitamin K, reviews guidelines, and explores alternative prophylaxis options.

Hemorrhage risk score and peripartum quantified blood loss.

Background: Risk assessment tools are used by clinicians to predict which patients might have excessive bleeding. We studied the association between a peripartum hemorrhage risk assessment score using peripartum quantified blood loss (QBL) among those with vaginal deliveries who are often at lower risk for peripartum hemorrhage.

Methods: In this retrospective analysis of 1221 patients with term vaginal deliveries at a public New York City hospital, the Association of Women's Health, Obstetric and Neonatal Nurses (AWOHNN) risk assessment tool was used to categorize patients as low risk, medium risk, or high risk for postpartum hemorrhage.

International workshop: what is needed to ensure outcome measures for Rett syndrome are fit-for-purpose for clinical trials? June 7, 2023, Nashville, USA.

Introduction: The clinical, research and advocacy communities for Rett syndrome are striving to achieve clinical trial readiness, including having fit-for-purpose clinical outcome assessments. This study aimed to (1) describe psychometric properties of clinical outcome assessment for Rett syndrome and (2) identify what is needed to ensure that fit-for-purpose clinical outcome assessments are available for clinical trials.

Methods: Clinical outcome assessments for the top 10 priority domains identified in the Voice of the Patient Report for Rett syndrome were compiled and available psychometric data were extracted.
