Divorce Rates Better Predict Population-Level Reproductive Success in Little Penguins Than Foraging Behaviour or Environmental Factors.

Understanding the relative contributions of environmental, behavioural and social factors to reproductive success is crucial for predicting population dynamics of seabirds. However, these factors are often studied in isolation, limiting our ability to evaluate their combined influence. This study investigates how marine environmental variables, foraging behaviour and social factors (divorce), influence reproductive success in little penguins () over 13 breeding seasons.

Cerebrovascular reactivity and response times describe recent ischaemic symptomatology in patients with moyamoya.

Moyamoya is a non-atherosclerotic intracranial steno-occlusive condition that places patients at high risk for ischaemic stroke. Randomized trials of surgical revascularization demonstrating efficacy in ischaemic moyamoya have not been performed, and as such, biomarkers of parenchymal haemodynamic impairment are needed to assist with triage and evaluate post-surgical response. In this prospective study, we test the hypothesis that parenchymal cerebrovascular reactivity (CVR) metrics in response to a fixed-inspired 5% carbon dioxide challenge correlate with recent focal ischaemic symptoms.

Concurrent preoperative eribulin and radiation for resectable retroperitoneal liposarcoma: a phase 1B study.

Background: Management of retroperitoneal liposarcoma (RPLPS) is challenging and recurrence rates remain high despite aggressive surgical resections. Preoperative radiation alone lacks definitive benefit, thus we sought to evaluate combined chemoradiotherapy with the potential to enhance local efficacy of radiation as well as control micrometastatic disease. We assessed the safety and tolerability of preoperative eribulin, a cytotoxic microtubule inhibitor approved for the treatment of advanced liposarcoma, in combination with radiation in patients with RPLPS.

Youth Homelessness in Denver, Colorado: 2017-2021.

Objectives: Homelessness is a public health crisis in the United States, yet homelessness prevalence, especially among children and youth, is not well understood. In this study, we use an indirect estimation method known as multiple systems estimation to further evaluate prevalence of youth experiencing homelessness in Denver, Colorado.

Methods: We performed a multiple systems estimation ("capture-recapture") analysis to estimate annual homelessness among youth aged 14 to 17 years in the city and county of Denver, Colorado from 2017 to 2021.
