Sarcopenia may predict recurrence in patients with head and neck cancer.

Background: Malnutrition is a major consequence of head and neck cancer (HNC), often leading to decreased skeletal muscle mass and impacting survival. The goal of this study is to determine the effect of sarcopenia, as defined by skeletal muscle index (SMI), on survival in patients with HNC.

Methods: This is a retrospective review of patients with HNC treated with surgery and/or radiation at a single tertiary care institute.

Transvenous embolization of a carotid-cavernous fistula via the inferior ophthalmic vein: illustrative case.

Background: A 49-year-old woman with a history of hypertension presented to the emergency department with right eye redness, proptosis, orbital fullness, and blurry vision. She had initially been diagnosed with an orbital pseudotumor, and the symptoms worsened over a course of steroids. Computed tomography angiography raised concern for a carotid-cavernous fistula (CCF), which was subsequently confirmed by digital subtraction angiography.

Evaluating Procedural Performance: A Composite Outcome for Aortic and Pulmonary Valvuloplasty in Congenital Cardiac Catheterization.

Background: Safety events and technical success (TS) have been previously reported for aortic and pulmonary valvuloplasty, but a composite performance measure as a novel, patient-centered strategy has neither been developed nor been studied. This study aims to refine a procedural performance (PP) variable, a composite of TS and procedural safety, for isolated, standard-risk aortic and pulmonary valvuloplasty.

Methods: A multicenter review was performed using data from the Congenital Cardiac Catheterization Project on Outcomes registry.

Apolipoproteine and Gene Variants Do Not Affect the Penetrance of Fragile X-Associated Tremor/Ataxia Syndrome.

In this study, the potential role and interaction of the and genes on the penetrance of fragile X-associated tremor/ataxia syndrome (FXTAS) and on the IQ trajectory were investigated. FXTAS was diagnosed based on molecular, clinical and radiological criteria. Males with the premutation (PM) over 50 years, 165 with and 34 without an FXTAS diagnosis, were included in this study and were compared based on their () and variant () genotypes.

Exploring the impact of age, and body condition score on erythrocytic B-Dependent transketolase activity in cats: A comprehensive analysis of thiamine status.

One of the key factors influencing aging and morbidity is the overall antioxidant status and regenerative capacity. In examining contributors to the antioxidant status, we analyzed the thiamine status in felines and the influence of age, gender, and body condition score. We measured erythrocytic B-dependent specific transketolase (STKT) activity, an enzyme in the pentose phosphate pathway, in a group of 60 sexually intact, healthy, and specific pathogen-free felines (44 females, 16 males, aged 1-17 years) with thiamine diphosphate (TDP; 0.

Osteochondroma-like parosteal osteosarcoma: A case highlighting diagnostic challenge and surgical advances.

Parosteal osteosarcomas are uncommon malignant bone tumors that arise from the bone surface. Their heterogenous components can present challenges in diagnosis. We present a case of a rare variant of this tumor known as an osteochondroma-like parosteal osteosarcoma, which was initially misdiagnosed as a cartilaginous tumor on core needle biopsy.

Safety outcomes of teclistamab accelerated dose escalation.

Introduction: Teclistamab, a bispecific T-cell engaging antibody targeting B-cell maturation antigen (BCMA), is indicated for the treatment of relapsed or refractory multiple myeloma after at least four lines of therapy. It has boxed warnings for life threatening cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). To mitigate these risks, teclistamab is initiated using step-up doses.

Total-Body Dynamic Imaging and Kinetic Modeling of [F]F-AraG in Healthy Individuals and a Non-Small Cell Lung Cancer Patient Undergoing Anti-PD-1 Immunotherapy.

Immunotherapies, especially checkpoint inhibitors such as anti-programmed cell death protein 1 (anti-PD-1) antibodies, have transformed cancer treatment by enhancing the immune system's capability to target and kill cancer cells. However, predicting immunotherapy response remains challenging. F-arabinosyl guanine ([F]F-AraG) is a molecular imaging tracer targeting activated T cells, which may facilitate therapy response assessment by noninvasive quantification of immune cell activity within the tumor microenvironment and elsewhere in the body.

Updates in Pediatric Sickle Cell Lung Disease.

Sickle cell lung disease presents a challenging care paradigm involving acute and chronic lower airway disease, sleep-disordered breathing, pulmonary vascular disease, and modification by environmental factors. Understanding the presentation, pathophysiology, and diagnostic approaches is essential for accurate identification and management. While significant progress has been made, there remains a need for research to develop effective treatments and interventions to decrease disease burden in these children.

The Current Status of Minimally Invasive Conduit Harvesting for Coronary Artery Bypass Grafting.

The harvesting of conduits for coronary artery bypass surgery has evolved over the last decade to include endoscopic approaches to access the saphenous vein, radial artery, and internal mammary artery. These minimally invasive techniques reduce the morbidity associated with open procedures by decreasing pain and recovery time and increasing mobility post operatively. This review highlights the differences in morbidity, quality, and patency between the most common conduits that are harvested minimally invasively for coronary artery bypass grafting surgery.

Outcomes of Kidney Transplants From Toxoplasma-Positive Donors: An Organ Procurement and Transplant Network Database Analysis.

There is a need to reconsider the acceptance of organs from donors considered suboptimal, in the absence of data. Toxoplasma antibody-positive donors (TPD) constitute one such group. The objective of our study was to compare graft survival in deceased donor renal transplant (Tx) recipients, stratified by Toxoplasma IgG status, using the Organ Procurement and Transplantation Network (OPTN) database.

Bariatric Surgery Is Associated with Lower Concentrations of Fecal Secondary Bile Acids and Their Metabolizing Microbial Enzymes: A Pilot Study.

Introduction: Excess body fat elevates colorectal cancer risk. While bariatric surgery (BRS) induces significant weight loss, its effects on the fecal stream and colon biology are poorly understood. Specifically, limited data exist on the impact of bariatric surgery (BRS) on fecal secondary bile acids (BA), including lithocholic acid (LCA), a putative promotor of colorectal carcinogenesis.

Pembrolizumab Plus Carboplatin and Paclitaxel as First-Line Therapy for Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma (KEYNOTE-B10): A Single-Arm Phase IV Trial.

Purpose: Standard-of-care first-line treatment for recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) is pembrolizumab plus platinum and fluorouracil (FU). However, FU is associated with potential challenges (continuous 4-day infusion, high administration costs, and cardiovascular and gastrointestinal toxicities), creating a clinical need for alternative chemotherapy combinations. We evaluated the efficacy and safety of first-line pembrolizumab plus carboplatin and paclitaxel for R/M HNSCC in the open-label, single-arm, phase IV KEYNOTE-B10 study (ClinicalTrials.

Impact of PROphet Test in Changing Physicians' Therapeutic Decision-Making for Checkpoint Immunotherapy in Non-Small-Cell Lung Cancer.

Purpose: Immune Checkpoint Inhibitor (ICI) regimens are approved for first-line treatment of metastatic nononcogene-driven NSCLC. Guidelines do not differentiate which patients with PD-L1 ≥ 50% should receive ICI monotherapy. The clinically validated PROphet NSCLC plasma proteomic-based test is designed to inform this therapeutic decision.
