Immune checkpoint inhibitor-induced severe epidermal necrolysis mediated by macrophage-derived CXCL10 and abated by TNF blockade.

Immune checkpoint inhibitors (ICI) represent new anticancer agents and have been used worldwide. However, ICI can potentially induce life-threatening severe cutaneous adverse reaction (SCAR), such as Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), hindering continuous ICI therapy. We examine 6 cohorts including 25 ICI-induced SJS/TEN patients and conduct single-cell RNA sequencing (scRNA-seq) analysis, which shows overexpression of macrophage-derived CXCL10 that recruits CXCR3 cytotoxic T lymphocytes (CTL) in blister cells from ICI-SJS/TEN skin lesions.

Comparing Time to Recovery Between Initial and Repeat Concussion in Athletes.

Objective: Compare time to recovery between initial and repeat concussions.

Design: Retrospective review of electronic medical record.

Setting: An interdisciplinary concussion clinic.

Seizing the Teachable Moment: A Pilot Study of Preventive Lifestyle Education in the Emergency Department.

Background Preventive measures are critical in avoiding and limiting the severity of diseases. Key lifestyle behaviors include sleep hygiene, habitual exercise, a healthy diet, and avoidance of risky substances, particularly the use of tobacco. The transtheoretical model (TTM) of change suggests that patients can move towards healthful changes through education.

Factors Associated with Pediatric Drowning-Associated Lung Injury.

Objective: To identify risk factors for clinically-important drowning-associated lung injury (ciDALI) in children.

Study Design: This was a cross-sectional study of children (0 through18 years) who presented to 32 pediatric emergency departments (EDs) from 2010 through 2017. We reviewed demographics, comorbidities, prehospital data, chest radiographs reports, and ED course from emergency medical services, medical, and fatality records.

The impact of training intervention on levels of indicator bacteria and prevalence of selected pathogens in raw milk from smallholder women dairy farmers in Central Ethiopia.

Contamination of milk is a serious public health risk, particularly in developing countries such as Ethiopia. Training is a tool for improving the quality and safety of milk. However, its effect on the microbial quality and safety of milk has not been well documented.

Epigenetic and Metabolic Landscape of Dementia with Lewy Bodies.

Background: Lewy body diseases, including dementia with Lewy bodies (DLB), are characterized by α-synuclein accumulation, leading to dementia. Previous studies suggest distinct epigenetic and metabolomic profiles in DLB.

Objective: This study aims to identify diagnostic biomarkers by analyzing the methylome and metabolome in the Brodmann area 7 of postmortem brain tissues from DLB patients and control subjects using multiomics approaches.

Proximity to Practice: The Role of Technology in the Next Era of Assessment.

The integration of technology into health professions assessment has created multiple possibilities. In this paper, we focus on the challenges and opportunities of integrating technologies that are used during clinical activities or that are completed by raters after a clinical encounter. In focusing on technologies that are more proximal to practice, we identify tradeoffs with different data collection approaches.

Virtual versus in-person didactic modalities: A national survey of emergency medicine residencies.

Background: Following the widespread shift from in-person to virtual delivery of didactics during the COVID-19 pandemic, some emergency medicine (EM) residency programs have retained virtual didactic time while others have returned exclusively to in-person didactics. In this national survey of EM residency programs, we explored the current national distribution of virtual versus in-person didactic time and the circumstances and motivators for use of each.

Methods: A cross-sectional survey with branched logic was designed via Qualtrics.

Transgender and Gender Diverse Patients Are Diagnosed with Borderline Personality Disorder More Frequently Than Cisgender Patients Regardless of Personality Pathology.

Purpose: Borderline personality disorder (BPD) is a severe form of psychopathology associated with a host of negative outcomes. Some literature suggests elevated prevalence among transgender and gender diverse (TGD) samples. Elevated BPD prevalence among TGD populations could be due to factors other than BPD-specific psychopathology.

Yes, We Can! Ensuring That our Graduating Resident's Procedural Skills Meet the Needs of Their Patients.

Objectives: There is a burgeoning discrepancy between the procedural competency of graduating diagnostic radiology residents and the needs of our patient population. The causes of this mismatch and opportunities for improvement are explored by the APDR Procedural Competency of Graduating DR Residents Task Force.

Materials And Methods: The APDR convened a task force consisting of diverse broad stakeholder viewpoints, drawing from organized radiology, academic and private practices.

Urogynecologic Care for Women Who Are Incarcerated.

In the United States, approximately 180,700 women are incarcerated across jails and prisons, comprising a demographic with an aging population and a higher growth rate compared to men. Despite this demographic trend, research into urogynecologic care for women who are incarcerated is notably lacking, with few studies addressing pelvic floor disorders such as incontinence, and even fewer focusing on access to treatment options like vaginal pessaries or surgical interventions. Women who are incarcerated may face unique challenges in obtaining urogynecologic care, including limited access to medical evaluations, invasive search procedures affecting intravaginal device use, and inadequate hygiene resources, all of which hinder effective management strategies.

PLK1 overexpression suppresses homologous recombination and confers cellular sensitivity to PARP inhibition.

The overexpression of Polo-like kinase 1 (PLK1) is associated with poor clinical outcomes in various malignancies, making it an attractive target for anticancer therapies. Although recent studies suggest PLK1's involvement in homologous recombination (HR), the impact of its overexpression on HR remains unclear. In this study, we investigated the effect of PLK1 overexpression on HR using bioinformatics and experimental approaches.

Comparative survival of sleeve gastrectomy versus Roux-en-Y gastric bypass in adults with obesity: a systematic review and meta-analysis.

Background: The difference in survival between sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) remains controversial.

Objective: To investigate the comparative survival difference between SG and RYGB in adults with morbid obesity.

Setting: A meta-analysis.

Differential Efficacy of Advanced Therapies in Inducing Remission in Ulcerative Colitis Based on Prior Exposure to TNF Antagonists.

Background And Aims: We sought to ascertain how prior exposure to TNF antagonists impacts treatment response with various classes of advanced therapies in patients with ulcerative colitis (UC), through a systematic review and meta-analysis.

Methods: Through a systematic review of multiple databases through June 30, 2024, we identified 17 RCTs in 8871 adults with moderate-severe UC who were treated with different advanced therapies vs. placebo, and reported efficacy in induction of clinical remission, stratified by prior exposure to TNF antagonists.

Splenic fibroblasts control marginal zone B cell movement and function via two distinct Notch2-dependent regulatory programs.

Innate-like splenic marginal zone (MZ) B (MZB) cells play unique roles in immunity due to their rapid responsiveness to blood-borne microbes. How MZB cells integrate cell-extrinsic and -intrinsic processes to achieve accelerated responsiveness is unclear. We found that Delta-like1 (Dll1) Notch ligands in splenic fibroblasts regulated MZB cell pool size, migration, and function.
