Changes in urinary concentrations of contemporary and emerging chemicals in commerce during the COVID-19 pandemic: Insights from the Environmental influences on Child Health Outcomes (ECHO) program.

Previous research indicates that the COVID-19 pandemic catalyzed alterations in behaviors that may impact exposures to environmental endocrine-disrupting chemicals. This includes changes in the use of chemicals found in consumer products, food packaging, and exposure to air pollutants. Within the Environmental influences on Child Health Outcomes (ECHO) program, a national consortium initiated to understand the effects of environmental exposures on child health and development, our objective was to assess whether urinary concentrations of a wide range of potential endocrine-disrupting chemicals varied before and during the pandemic.

Impact of Subsequent Fellowship on Urology Chief Resident Case Log Volumes.

Objective: To characterize the impact of subsequent fellowship on the case log experience of trainees throughout their residency and specifically their chief resident year.

Materials And Methods: Urology resident case logs from 2010 to 2022 were obtained from 13 institutions for total residency and chief years. Five categorized index procedures were included for analysis: General Urology; Endourology; Reconstructive Urology; Urologic Oncology; and Pediatric Urology.

Multi-Institutional Analysis of Surgery for Lichen Sclerosus Induced Penile Urethral Stricture: Establishing Single-Stage Urethroplasty as a Primary Treatment Option.

Introduction: Ideal treatment of lichen sclerosus (LS) induced penile urethral strictures (PUS) remains elusive. The objective of this study is to compare multi-institutional outcomes of single-stage urethroplasty (SSU) with oral mucosal graft (OMG), staged urethroplasty and perineal urethrostomy (PU) for treatment of LS induced PUS.

Methods: Multi-institutional analysis was performed at 9 centers on males undergoing SSU, staged urethroplasty or PU for LS induced PUS.

Assessing the clinical utility of pre-operative neutrophil-lymphocyte ratio as a predictor of clinicopathological parameters in patients being treated for primary breast cancer.

Background: There is a paucity of data supporting the role of neutrophil-lymphocyte ratios (NLR) to determine clinicopathological parameters in patients being treated for primary breast cancer.

Aims: To evaluate the association between pre-operative NLR and clinicopathological parameters in patients diagnosed with breast cancer.

Methods: A retrospective cohort study was performed.

Extracorporeal Membrane Oxygenation in Children with Pulmonary Atresia and Intact Ventricular Septum: Mortality and Associated Outcomes.

Data on outcomes of extracorporeal membrane oxygenation (ECMO) are limited in patients with pulmonary atresia intact ventricular septum (PAIVS). The objective of this study was to describe the use of ECMO and the associated outcomes in patients with PAIVS. We retrospectively reviewed neonates with PAIVS who received ECMO between 2009 and 2019 in 19 US hospitals affiliated with the Collaborative Research for the Pediatric Cardiac Intensive Care Society (CoRe-PCICS).
