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.

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.

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.

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.

Externalizing traits and behaviors are broadly defined by impairments in self-regulation and impulse control that typically begin in childhood and adolescence. Externalizing behaviors, traits, and symptoms span a range of traditional psychiatric diagnostic categories. In this study, we sought to generate an algorithm that could reliably identify transdiagnostic childhood-onset externalizing cases and controls within a university hospital electronic health record (EHR) database.

This project's main aim was to determine which intervention modality was more effective with students across two school districts with varying degrees of rurality (in-person delivery vs. remote delivery).

Despite increasing incidence of renal cell carcinomas <4 cm, up to 1/3 of patients diagnosed with RCC exhibit metastatic disease (mRCC) at time of diagnosis. Cytoreductive nephrectomy (CN), a procedure which encompasses the surgical removal of the primary tumor in patients with metastatic disease, was offered upfront as standard of care during the cytokine era; however, as systemic treatment has evolved, the role of CN in mRCC patients has become less clear.

Treatments include oral hydroxyurea, blood transfusions, and hematopoietic stem cell transplantation (HSCT). Our objective was to evaluate the neurologic relevance of these therapies by characterizing how treatment-induced changes in hemoglobin (Hb) affect brain health biomarkers.

Materials formed with thiol-norbornene chemistry are amenable to thiol-peptide patterning, and this study reports the rational design of synthetic receptors that reversibly activate cellular responses based on peptide-ligand recognition. This transmembrane receptor platform, termed Extracellular Peptide-ligand Dimerization Actuator (EPDA), consists of stimulatory or inhibitory receptor pairs that come together upon extracellular peptide dimer binding with corresponding monobody receptors.

Light chain escape (LCE) is a clinical phenomenon observed when light chains rise separately from M-spike values, implying divergent tumor evolution. We sought to understand LCE by performing high depth transcriptomic and phenotypic studies.

In 2021, approximately 473,000 veterans misused opioids in the past year. In the context of their military service and post-service life, Veterans with OUD often encounter unique barriers to recovery, including the reintegration into civilian society and the pursuit of stable, meaningful employment.

Objective: To investigate the efficacy, safety, and tolerability of brexpiprazole and sertraline combination treatment (brexpiprazole + sertraline) compared with sertraline + placebo for PTSD.
Design, Setting, And Participants: This was a parallel-design, double-blind, randomized clinical trial conducted from October 2019 to August 2023.
F-dependent glucose-6-phosphate dehydrogenase (FGD) catalyzes the conversion of glucose-6-phosphate (G6P) to 6-phosphogluconolactone, using cofactor F as the hydride transfer acceptor. Our previous pH dependence studies suggested that E109 serves as an active site acid, donating a proton to the N-1 position of F, while leaving the role of H40 unanswered, which was previously suggested to serve as the active site base. This work utilizes thermodynamic and kinetic studies to elucidate additional mechanistic details concerning the roles of H40 and E13.

Purpose: This study evaluated the development and progression of clinical judgment in simulation throughout a prelicensure bachelor of science in nursing (BSN) program using the Lasater Clinical Judgment Rubric (LCJR).
Background: Health system websites are important resources to guide health care decisions and may be useful tools to improve racial equity in access to living donor kidney transplant (LDKT).
Methods: We performed a cross-sectional study of adult LDKT programs in the United States. We created an assessment tool for website quality across three domains: accessibility (access to LDKT specific information from the transplant center website), readability (ease of reading and clarity), and educational content (appropriateness and presentation of information, LDKT-specific content, program-specific characteristics, and adherence to equity-centered principles of web design).

Methods: This genetic epidemiology study examined the sex-specific association between the genetic risk of 3 psychiatric disorders (major depression [MD], schizophrenia, and bipolar disorder), estimated using polygenic scores (PGSs), and risks of 3 CVDs (atrial fibrillation [AF], coronary artery disease [CAD], and heart failure [HF]) in 345 169 European-ancestry individuals (UK Biobank), with analyses replicated in an independent BioVU cohort (n=49 057). Mediation analysis was conducted to determine whether traditional CVD risk factors could explain any observed sex difference.
Staghorn calculi pose challenges in urology, often necessitating more invasive procedures such as percutaneous nephrolithotomy (PCNL) to clear a large stone burden with fewer procedures. Here we present a case of a 76-year-old female with chronic kidney disease and a malrotated right pelvic kidney who underwent PCNL for a 3.5 cm staghorn calculus.

However, repeated exposure to flavors, even unpleasant vegetable flavors, improves acceptability. Yet, increasing exposure to vegetables is difficult, as vegetables can be less convenient, available, and affordable than other foods.

Methods: We completed an open-label, randomised clinical trial in patients with grade 2 or 3, stage III undifferentiated pleomorphic sarcoma or dedifferentiated or pleomorphic liposarcoma of the extremity and limb girdle.
Patients with sickle cell disease (SCD) are at elevated risk of silent cerebral infarcts and strokes; however, they frequently lack established stroke risk factors (e.g., macrovascular arterial steno-occlusion) and as such the mechanisms underlying such events are incompletely characterized.
