Major Perioperative Bleeding in Patients on Dialysis Undergoing Nonelective Abdominal Surgeries.

Introduction: Patients with end-stage renal disease (ESRD) are at increased risk for bleeding complications following surgery. However, the approach to the preoperative risk assessment and risk reduction, if feasible, in ESRD patients undergoing nonelective abdominal surgery has not been comprehensively studied. We aim to determine the prevalence and risk factors for perioperative bleeding in patients on dialysis undergoing nonelective abdominal surgery.

Low Rates of Short-Term Anastomotic Complications After Kono-S versus Side-to-Side Stapled Anastomosis.

Introduction: The Kono-S (KS) anastomosis for Crohn's disease (CD) is associated with improved endoscopic and clinical long-term outcomes. Ileocolonic anastomoses in CD are associated with an unacceptable anastomotic complication rate - up to 40%. Investigation of short-term benefits of KS is thus warranted.

Characteristics and variations in young adults with cutaneous melanoma: A national cancer database analysis.

Background And Objectives: Many cancers in young adulthood differ in terms of biology, histologic variation, and prognosis compared to cancer in other older age groups. Differences in cutaneous melanoma among young adults compared to other older age groups, as well as between sexes in young adults are not well studied.

Methods: The National Cancer Database was queried for patients diagnosed with cutaneous melanoma between 2004 and 2017.

A Case Report of Refractory Graft-Versus-Host Disease Colitis Managed With Robotic Total Abdominal Colectomy.

Graft-versus-host disease (GvHD) is a common complication following hematopoietic stem cell transplant (HSCT) and has protean manifestations. It results from the activation of transplanted T lymphocytes against the HLA antigens of recipient cells, resulting in tissue destruction. The most commonly involved sites of acute GvHD are the skin and gut, with high mortality reported in the latter.

Data-Driven Surveillance Protocol for Patients at Risk for Peritoneal Recurrence of Primary Colon Cancer: Surveillance for Peritoneal Carcinomatosis.

Peritoneal carcinomatosis (PC) is rarely discovered early due to low sensitivity of screening imaging and tumor markers, however, earlier identification may improve outcomes. This study assesses risk factors and time to recurrence of PC and implementation of a surveillance system. Patients with stage II-III colon adenocarcinoma undergoing curative colectomy between 2005-2022 were retrospectively reviewed at a single tertiary care institution.

Association between Medicaid Expansion and Cutaneous Melanoma Diagnosis and Outcomes: Does Where You Live Make a Difference?

Background: Early detection and standardized treatment are crucial for enhancing outcomes for patients with cutaneous melanoma, the commonly diagnosed skin cancer. However, access to quality health care services remains a critical barrier for many patients, particularly the uninsured. Whereas Medicaid expansion (ME) has had a positive impact on some cancers, its specific influence on cutaneous melanoma remains understudied.

Chronic Intermittent Hypoxia-Induced Diaphragm Muscle Weakness Is NADPH Oxidase-2 Dependent.

Chronic intermittent hypoxia (CIH)-induced redox alterations underlie diaphragm muscle dysfunction. We sought to establish if NADPH oxidase 2 (NOX2)-derived reactive oxygen species (ROS) underpin CIH-induced changes in diaphragm muscle, which manifest as impaired muscle performance. Adult male mice (C57BL/6J) were assigned to one of three groups: normoxic controls (sham); chronic intermittent hypoxia-exposed (CIH, 12 cycles/hour, 8 h/day for 14 days); and CIH + apocynin (NOX2 inhibitor, 2 mM) administered in the drinking water throughout exposure to CIH.

Tumi Flap: A Novel Modification to Frontal Flap for Orbital Exenteration Defects.

Orbital exenteration remains a significant disfigurement in the face. Many reconstructive options were reported for one stage covering the defects. Local flaps are used primarily in elderly patients who are not candidates for microvascular procedures.

"All of the things to everyone everywhere": A mixed methods analysis of community perspectives on equitable access to monoclonal antibody treatment for COVID-19.

Background: Neutralizing monoclonal antibody (mAb) treatment for COVID-19 prevents hospitalization and death but is underused, especially in racial/ethnic minority and rural populations. Reasons for underuse and inequity may include community member lack of awareness or healthcare access barriers, among others. This study assessed mAbs community awareness and opportunities for improving equitable mAb access.

Low resilience in severe obesity: marker of adverse childhood experiences and current psychological disorders.

Purpose: Psychological disorders, early-age psychological traumas and eating disorders may contribute to the development of severe obesity in vulnerable individuals. Resilience may serve a protective role against binge eating disorder or depression. The current study aimed to investigate the relationship between adverse childhood experiences (ACE), resilience, and current psychological disorders.

NADPH oxidase 2 is necessary for chronic intermittent hypoxia-induced sternohyoid muscle weakness in adult male mice.

New Findings: What is the central question of this study? Exposure to chronic intermittent hypoxia (CIH) evokes redox changes, culminating in impaired upper airway muscle function: what is the specific source of CIH-induced reactive oxygen species? What is the main finding and its importance? Profound sternohyoid muscle dysfunction following exposure to CIH was entirely prevented by apocynin co-treatment or NADPH oxidase 2 (NOX2) deletion. The results have implications for human obstructive sleep apnoea syndrome and point to antioxidant intervention, potentially targeting NOX2 blockade, as a therapeutic strategy.

Abstract: Exposure to chronic intermittent hypoxia (CIH) evokes redox changes, culminating in impaired upper airway muscle function.

Five-Year Changes in Weight and Diabetes Status After Bariatric Surgery for Craniopharyngioma-Related Hypothalamic Obesity: a Case-Control Study.

Purpose: Craniopharyngiomas are tumors located in the hypothalamic region which leads to obesity in about 50% of cases. Long-term efficacy and safety of bariatric surgery are lacking in this peculiar population. The aim of this study is to determine the 5-year weight loss and resolution of type 2 diabetes (T2D) after bariatric surgery in patients operated on craniopharyngioma who had developed hypothalamic obesity.

Insulin resistance is more severe in patients with primary hyperparathyroidism.

Background: Primary hyperparathyroidism is associated with an increased cardiovascular mortality, and its underlying mechanisms remain unclear. Insulin resistance has been suggested with low level of evidence. The goal of this study was to evaluate glucose metabolism and insulin resistance in primary hyperparathyroidism patients, to compare with control subjects, and to identify risk factors for insulin resistance in patients with primary hyperparathyroidism.

SnRNA sequencing defines signaling by RBC-derived extracellular vesicles in the murine heart.

Extracellular vesicles (EVs) mediate intercellular signaling by transferring their cargo to recipient cells, but the functional consequences of signaling are not fully appreciated. RBC-derived EVs are abundant in circulation and have been implicated in regulating immune responses. Here, we use a transgenic mouse model for fluorescence-based mapping of RBC-EV recipient cells to assess the role of this intercellular signaling mechanism in heart disease.

The cardiac molecular setting of metabolic syndrome in pigs reveals disease susceptibility and suggests mechanisms that exacerbate COVID-19 outcomes in patients.

Although metabolic syndrome (MetS) is linked to an elevated risk of cardiovascular disease (CVD), the cardiac-specific risk mechanism is unknown. Obesity, hypertension, and diabetes (all MetS components) are the most common form of CVD and represent risk factors for worse COVID-19 outcomes compared to their non MetS peers. Here, we use obese Yorkshire pigs as a highly relevant animal model of human MetS, where pigs develop the hallmarks of human MetS and reproducibly mimics the myocardial pathophysiology in patients.

Impact of severe SARS-CoV-2 infection on nutritional status and subjective functional loss in a prospective cohort of COVID-19 survivors.

Unlabelled: The nutritional sequelae of COVID-19 have not been explored in a large cohort study.

Objectives: To identify factors associated with the change in nutritional status between discharge and 30 days post-discharge (D30). Secondary objectives were to determine the prevalence of subjective functional loss and severe disability at D30 and their associated factors.

Obesity and mortality in critically ill COVID-19 patients with respiratory failure.

Background: Patients with obesity are at increased risk of severe COVID-19, requiring mechanical ventilation due to acute respiratory failure. However, conflicting data are obtained for intensive care unit (ICU) mortality.

Objective: To analyze the relationship between obesity and in-hospital mortality of ICU patients with COVID-19.

Genitourinary complications in orthopaedic surgery.

Genitourinary complications following orthopaedic intervention are uncommon but well-described occurrences and exist on a spectrum of severity. These complications vary depending on the anatomic location and surgical approach, with surgery of the spine, hip, and pelvis of particular concern. Injuries to the urinary tract may present acutely with urinary retention or hematuria.
