Differences in Pulmonary Artery Flow Hemodynamics Between PAH and PH-HFpEF: Insights From 4D-Flow CMR.

Pulmonary artery (PA) flow analysis is crucial for understanding the progression of pulmonary hypertension (PH). We hypothesized that PA flow characteristics vary according to PH etiology. In this study, we used 4D flow cardiovascular magnetic resonance imaging (CMR) to compare PA flow velocity and wall shear stress (WSS) between patients with pulmonary arterial hypertension (PAH) and those with heart failure with preserved ejection fraction and pulmonary hypertension (PH-HFpEF).

Assessment of Inflammatory Biomarkers and Incident Atrial Fibrillation in Older Adults.

Background: Available evidence supports the importance of inflammation in atrial fibrillation (AF) pathogenesis, yet general anti-inflammatory therapies have failed to show benefit for prevention of the arrhythmia. Better understanding of the specific inflammatory pathways involved is necessary to advance therapeutics.

Methods And Results: We evaluated 9 circulating markers of inflammation measured by immunoassays and incidence of AF in a population-based older cohort.

Accidental tracheostomy decannulation: Risk factors and complications in pediatric patients using the NSQIP-P database.

Background: Accidental tracheostomy decannulation (ATD) is a life-threatening event in pediatric patients. The factors associated with ATD in children are largely unknown. Utilizing the National Surgical Quality Improvement Pediatric (NSQIP-P) dataset, we sought to identify the incidence of ATD and associated factors.

Clearing-enabled light sheet microscopy as a novel method for three-dimensional mapping of the sensory innervation of the mouse knee.

A major barrier that hampers our understanding of the precise anatomic distribution of pain sensing nerves in and around the joint is the limited view obtained from traditional two dimensional (D) histological approaches. Therefore, our objective was to develop a workflow that allows examination of the innervation of the intact mouse knee joint in 3D by employing clearing-enabled light sheet microscopy. We first surveyed existing clearing protocols (SUMIC, PEGASOS, and DISCO) to determine their ability to clear the whole mouse knee joint, and discovered that a DISCO protocol provided the optimal transparency for light sheet microscopy imaging.

Prevalent Atherosclerotic Cardiovascular Disease Among Veterans by Sexual Orientation.

Background: Seven million lesbian, gay, and bisexual (LGB) adults will be aged >50 years by 2030; assessing and addressing their risk for cardiovascular disease is critical.

Methods And Results: We analyzed a nationwide cohort using the Veterans Health Administration data. Sexual orientation (SO) was classified via a validated natural language processing algorithm.

Hearing loss during chemotherapy: prevalence, mechanisms, and protection.

Ototoxicity is an often-underestimated sequela for cancer patients undergoing chemotherapy, with an incidence rate exceeding 50%, affecting approximately 4 million individuals worldwide each year. Despite the nearly 2,000 publications on chemotherapy-related ototoxicity in the past decade, the understanding of its prevalence, mechanisms, and preventative or therapeutic measures remains ambiguous and subject to debate. To date, only one drug, sodium thiosulfate, has gained FDA approval for treating ototoxicity in chemotherapy.

Methodological Approaches for Measuring the Association Between Heat Exposure and Health Outcomes: A Comprehensive Global Scoping Review.

Objective: To synthesize the methodologies of studies that evaluate the impacts of heat exposure on morbidity and mortality.

Outcomes of heliox use in children with respiratory compromise: A 10-year single institution experience.

Objective: Heliox, a mixture of helium and oxygen, has been shown to improve laminar airflow and decrease airway resistance in children. This study aims to describe the outcomes of heliox use in children with respiratory compromise and to identify variables associated with a need for airway surgical intervention.

Methods: A retrospective cohort study of patients who received heliox between 2012 and 2022 at a tertiary care children's hospital.

Utility of dynamic contrast enhancement for clinically significant prostate cancer detection.

Objective: This study aimed to evaluate the association of dynamic contrast enhancement (DCE) with clinically significant prostate cancer (csPCa, Gleason Grade Group ≥2) and compare biparametric magnetic resonance imaging (bpMRI) and multiparametric MRI (mpMRI) nomograms.

Subjects/patients And Methods: We identified a retrospective cohort of biopsy naïve patients who underwent pre-biopsy MRI separated by individual MRI series from 2018 to 2022. csPCa detection rates were calculated for patients with peripheral zone (PZ) lesions scored 3-5 on diffusion weighted imaging (DWI) with available DCE (annotated as - or +).

Improving possible serious bacterial infection (PSBI) management in young infants when referral is not feasible: lessons from embedded implementation research in Ethiopia and Kenya.

Background: Sepsis is a leading cause of neonatal mortality, despite the availability of effective treatment of possible serious bacterial illness (PSBI), including when referral to a hospital is not feasible. Gaps in access and delivery worsened during COVID-19. We conducted embedded implementation research in Ethiopia and Kenya aimed at mitigating the impact of COVID-19 and addressing various implementation challenges to improve PSBI management.
