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.

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.

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.
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.
Background: Most approaches to healthcare reform envision an enhanced role for primary care providers, supported by innovative payment methodology and improved resources. However, there are currently no instruments to measure providers' ability and willingness to work with existing tools provided by payers, such as Accountable Care Organizations (ACO). In this study, we develop and psychometrically test a new instrument to measure provider engagement with ACOs.
