Does resident involvement impact postoperative outcomes after proximal humerus fractures?

Background: Proximal humerus fractures (PHFs) are a prevalent orthopedic injury and often require surgical intervention. These surgeries frequently involve resident participation as part of their training, but the impact of this involvement on surgical outcomes remains unclear. This study evaluates the effect of resident participation on perioperative complications and mortality in PHF surgeries.

Vitamin D deficiency is associated with adverse medical outcomes following total shoulder arthroplasty.

Background: Vitamin D deficiency, or hypovitaminosis D, is linked to poor surgical outcomes. Its effect on total shoulder arthroplasty (TSA) remains unclear. This study assesses the association between vitamin D deficiency and postoperative complications following TSA.

Medical Adhesive-Related Skin Injury After Reverse Total Shoulder Arthroplasty: A Case Report.

Case: A 77-year-old woman with osteoarthritis underwent reverse total shoulder arthroplasty (RTSA) after her surgical site had been preoperatively prepped with 3M Ioban iodine-impregnated drapes. She developed a medical adhesive-related skin injury (MARSI) after the removal of the Ioban. The iatrogenic lesion was treated in coordination with plastic surgery and wound care teams at our institution.

Racial disparities in early postoperative proximal humerus fracture outcomes: Do minorities face longer operative times, extended hospital stays, and higher risks?

Background: Racial disparities in orthopedic surgery outcomes have been extensively documented, highlighting systemic biases in care. Proximal humerus fractures (PHFs), about 6% of all fractures, are rising, especially among the elderly. Despite the prevalence of PHFs, a research gap exists regarding racial disparities in postoperative complications and outcomes.

ChatGPT-4 Knows Its A B C D E but Cannot Cite Its Source.

Introduction: The artificial intelligence language model Chat Generative Pretrained Transformer (ChatGPT) has shown potential as a reliable and accessible educational resource in orthopaedic surgery. Yet, the accuracy of the references behind the provided information remains elusive, which poses a concern for maintaining the integrity of medical content. This study aims to examine the accuracy of the references provided by ChatGPT-4 concerning the Airway, Breathing, Circulation, Disability, Exposure (ABCDE) approach in trauma surgery.

Standardized In Vitro Models of Human Adipose Tissue Reveal Metabolic Flexibility in Brown Adipocyte Thermogenesis.

Functional human brown and white adipose tissue (BAT and WAT) are vital for thermoregulation and nutritional homeostasis, while obesity and other stressors lead, respectively, to cold intolerance and metabolic disease. Understanding BAT and WAT physiology and dysfunction necessitates clinical trials complemented by mechanistic experiments at the cellular level. These require standardized in vitro models, currently lacking, that establish references for gene expression and function.
