Cost-Effectiveness Analysis of a Novel Fetal Vesicoamniotic Shunt-The Vortex Shunt.

Objective: We estimated the potential outcomes, costs, and cost-effectiveness of the Vortex shunt, a novel fetal vesicoamniotic shunt (VAS), compared to standard shunts for treating fetal lower urinary tract obstruction (LUTO).

Method: We designed a decision-analytic model comparing the Vortex shunt to current shunts using a theoretical cohort of 1000 pregnancies equivalent to the annual U.S.

Validity and use of the Neonatal Infant Stressor Scale: An integrative review.

Background: Stress exposure, operationalized as a count of painful or skin-breaking breaking procedures, is an important concept for inclusion in studies of preterm infants. The Neonatal Infant Stressor Scale (NISS) was developed to also account for nonpainful and environmental stressors; however, validity of this measure is unknown.

Aims: The purpose of this review was to define the breadth of use of the NISS in neonatal research studies and determine its predictive and concurrent validity.

Extreme Reactive Thrombocytosis Caused by Obstructive Nephrolithiasis and Pyelonephritis.

Platelet counts in reactive thrombocytosis rarely exceed 1000 × 10/L. We present the case of a male patient, aged 80 years, with quiescent rheumatoid arthritis who was found to have a platelet count of 1011 × 10/L on routine laboratory testing. The patient was initially asymptomatic but developed leukocytosis to 23.

Sex-specific social aging in wild African lions.

There is a growing interest in social behavior change with age, and the impacts of sociality on longevity, but current knowledge is broadly limited to primates, societies structured by dominance hierarchies, or single-sex studies. It is less clear how social aging patterns emerge in carnivores. The African lion (Panthera leo), a species that lives in egalitarian fission-fusion societies, presents an exceptional opportunity to examine social aging.

Multifaceted density dependence: Social structure and seasonality effects on Serengeti lion demography.

Interactions between density and environmental conditions have important effects on vital rates and consequently on population dynamics and can take complex pathways in species whose demography is strongly influenced by social context, such as the African lion, Panthera leo. In populations of such species, the response of vital rates to density can vary depending on the social structure (e.g.
