In Vivo Visualization of Intravascular Patrolling Immune Cells in the Primate Eye.

Purpose: Insight into the immune status of the living eye is essential as we seek to understand ocular disease and develop new treatments. The nonhuman primate (NHP) is the gold standard preclinical model for therapeutic development in ophthalmology, owing to the similar visual system and immune landscape in the NHP relative to the human. Here, we demonstrate the utility of phase-contrast adaptive optics scanning light ophthalmoscope (AOSLO) to visualize immune cell dynamics on the cellular scale, label-free in the NHP.

Sex-Specific Skeletal Muscle Gene Expression Responses to Exercise Reveal Novel Direct Mediators of Insulin Sensitivity Change.

Background: Understanding the causal pathways, systems, and mechanisms through which exercise impacts human health is complex. This study explores molecular signaling related to whole-body insulin sensitivity (Si) by examining changes in skeletal muscle gene expression. The analysis considers differences by biological sex, exercise amount, and exercise intensity to identify potential molecular targets for developing pharmacologic agents that replicate the health benefits of exercise.

Medical Malpractice in Otolaryngology within the United States: A LexisNexis-Based Demographic Analysis.

Objective: Otolaryngologists are at a significantly greater risk of being sued than most other physicians. To date, there is a lack of studies characterizing trends in otolaryngology malpractice claims. To assess these trends and risk variables, this study examined malpractice claims against otolaryngologists.

Long-term contributions of VOC sources and their link to ozone pollution in Bronx, New York City.

Changes in energy and environmental policies along with changes in the energy markets of New York State over the past two decades, have spurred interest in evaluating their impacts on emissions from various energy generation sectors. This study focused on quantifying these effects on VOC (volatile organic compounds) emissions and their subsequent impacts on air quality within the New York City (NYC) metropolitan area. NYC is an EPA nonattainment region for ozone (O) and likely is a VOC limited region.

PPARγ drives mitochondrial stress signaling and the loss of atrial cardiomyocytes in newborn mice exposed to hyperoxia.

Diastolic dysfunction is increasingly common in preterm infants exposed to supplemental oxygen (hyperoxia). Previous studies in neonatal mice showed hyperoxia suppresses fatty acid synthesis genes required for proliferation and survival of atrial cardiomyocytes. The loss of atrial cardiomyocytes creates a hypoplastic left atrium that inappropriately fills the left ventricle during diastole.

Cost-Effectiveness of Lung Cancer Screening with Low-Dose Computed Tomography: Comparing Hungarian Screening Protocols with the US NLST.

We aimed to directly compare the cost-effectiveness of Hungarian (following the NELSON trial) and NLST screening protocols, two trials influencing lung-cancer-screening implementation internationally. A decision-analytic model analyzing the cost-effectiveness of Hungarian protocols was manipulated to reflect the protocols of the NLST, while maintaining features specific to the Hungarian healthcare setting. In the Hungarian protocol, there are three possible outcomes to the initial round of screening, positive, negative, and indeterminate, indicating an uncertain degree of suspicion for lung cancer.

Recruitment of informal caregivers into community oncology research studies: results from the 2022 Landscape Assessment.

Understanding the experiences of community oncology practices in recruiting informal (unpaid/family) caregivers into research studies can inform strategies to improve caregiver enrollment. We used data from the 2022 National Cancer Institute Community Oncology Research Program (NCORP) Landscape Assessment to describe the experience of recruiting informal caregivers for research studies in community oncology practices. Among 258 practice groups, only one-third (30%, 78/258) reported prior experience recruiting informal caregivers for research studies.

Atypical Hangman's Fractures: An Institutional Study of 51 Patients With Atypical Traumatic Spondylolisthesis of C2.

Study Design: Retrospective cohort study.

Objectives: Atypical hangman's fractures are associated with increased risk for neurologic injury due to involvement of the posterior cortex of the axis body. We present the largest single-center cohort of atypical hangman's fractures with the goal of guiding treatment decisions and outcomes based on fracture classification.

Clinical Significance of Tumor Location for Ureteroscopic Tumor Grading in Upper Tract Urothelial Carcinoma.

Although previous literature shows tumor location as a prognostic factor in upper tract urothelial carcinoma (UTUC), there remains uninvestigated regarding the impact of tumor location on grade concordance and discrepancies between ureteroscopic (URS) biopsy and final radical nephroureterectomy (RNU) pathology. In this international study, we retrospectively reviewed the records of 1,498 patients with UTUC who underwent diagnostic URS with concomitant biopsy followed by RNU between 2005 and 2020. Tumor location was divided into four sections: the calyceal-pelvic system, proximal ureter, middle ureter, and distal ureter.

Knowledge and beliefs about lung cancer screening among Black individuals at high risk: a qualitative approach.

Background: Despite its efficacy in reducing lung cancer (LC)-specific mortality by 20%, screening with low-dose computed tomography (LDCT) in eligible groups remains low (5-16%). Black individuals are more commonly affected by LC than other racial/ethnic groups in the United States (U.S.

Associations of quality of social support and accurate beliefs about curability among older adults with advanced cancer.

Introduction: Supporting older adults with advanced cancer to better understand their disease and its prognosis is important for shared decision-making. Social support is a potentially modifiable factor that may influence disease understanding. In this study, we examined the associations of quantity and quality of social support with patients' beliefs about the curability of their advanced cancer.

CHADS-VASc predicts readmission, outcomes and resource utilization in patients undergoing coronary artery bypass grafting: A 7-year National Readmission Database study.

Background: CHA2DS2-VASc score is used to assess thromboembolic risk in patients with atrial fibrillation (AF)/atrial flutter (AFL), however its utilization to predict outcomes and readmission at following discharge in patients undergoing coronary artery bypass grafting (CABG) regardless of AF/AFL presence is understudied. We sought to assess its utility in predicting outcomes, length of hospital stay (LOS), and healthcare-associated costs (HAC) in these patients.

Method: The National Readmission Database (NRD) was queried from 2010 to 2017 for patients with/without AF/AFL undergoing CABG using the International Classification of Diseases, Ninth and Tenth editions (ICD-9-&-10).

"Sorry, no results found": evaluating LGBTQIA + inclusivity of U.S. cancer centers' websites.

Purpose: Cancer care for lesbian, gay, bisexual, transgender, queer, intersex, asexual, and other sexuality and gender diverse (LGBTQIA +) individuals is marked by disparities stemming from a history of discrimination, stigma, and systemic inequities. For LGBTQIA + individuals seeking cancer care, cancer center websites may be a first point of contact with healthcare. Two complementary studies sought to evaluate the LGBTQIA + inclusivity of cancer centers' websites.

Cost Comparison of a Traditional Didactic versus National Flipped Classroom Curriculum.

Objective:  We compared the cost of faculty time preparing educational materials for traditional didactic (TD) education provided at local institutions with that of faculty time preparing National Neonatology Curriculum (NNC) flipped classroom (FC) educational materials shared among institutions for fellow education across the United States.

Study Design:  Using survey data and the national average for faculty educators' salaries, we calculated the cost of developing TD versus FC materials. Wilcoxon rank-sum test and comparison of two Poisson rates were utilized to evaluate the time to create versus update TD materials and the cost to create new TD versus FC materials, respectively.
