Article Abstract
Purpose: This study sought to determine whether the type of oral and maxillofacial surgery (OMS) practice dictated the complexity of patients encountered for orthognathic surgery and to determine whether there were meaningful differences in comorbidities between patient groups.
Materials And Methods: This was a retrospective cohort study of orthognathic surgical patients operated on by surgeons at an academic medical center (AMC; OMS department at the University of Alabama-Birmingham) compared with a private practice (PP) group that also operated at the AMC auxiliary facility. Surgical procedures included in this study were Le Fort osteotomy, bilateral sagittal split osteotomy, genioplasty, and combinations of these procedures. An experienced surgeon scrutinized the medical records of the AMC and PP groups for age, gender, medical history, American Society of Anesthesiologists (ASA) classification, and indications for surgical procedures. These data were statistically compared for differences in patient complexity.
Results: The average age of patients in the 2 groups was similar (AMC, 29 yr; PP, 27 yr). Many more females were treated in the PP setting (male-to-female ratio, 1.06:1 in the AMC group and 1:1.6 in the PP group). The AMC group had a larger percentage of patients with medical comorbidities, a larger proportion of patients with ASA class 2 or 3, and a larger proportion of patients who underwent procedures for reasons other than malocclusion or cosmetic purposes, and these proportions were statistically relevant. Average length of surgery and average length of stay were longer in the AMC group.
Conclusion: This retrospective cohort study suggests that OMS departments in AMCs tend to treat orthognathic surgical patients with increased comorbidities and systemic illnesses and operate on a larger percentage of patients with concomitant dentofacial issues versus more routine dentofacial skeletal and occlusion deformities.

Warfarin is a widely used vitamin K antagonist (VKA) with known pleiotropic effects beyond anticoagulation. Preclinical and case-control evidence suggests that warfarin may affect hematopoiesis, but longitudinal human evidence is lacking. To explore this potential effect, we conducted a post-hoc analysis of participants in the Hokusai-VTE and ENGAGE AF-TIMI 48 trials, which randomized patients to warfarin or the direct oral anticoagulant edoxaban with routine laboratory testing at predefined follow-up visits.

Background: Knee osteoarthritis (KOA) is a prevalent degenerative joint disorder that significantly impairs physical function and daily activities. While conventional treatments focus on symptom management, complementary therapies such as aromatherapy massage have gained attention for their potential benefits.
Objective: This study evaluates the effects of peppermint oil aromatherapy massage on functional impairments in KOA patients.

Wearable bioelectronics have transformed modern biomedical applications by enabling seamless integration with biological tissues, providing continuous, comprehensive, and personalized healthcare. Skin cancer, particularly melanoma, poses a significant clinical challenge due to its high metastatic potential and associated mortality. Traditional diagnostic approaches face limitations in accuracy, accessibility, and reproducibility, while existing treatments are often constrained by systemic toxicity and therapeutic resistance.

Background: There is conflicting literature regarding mortality outcomes associated with REBOA usage in patients with severe thoracic or abdominal trauma. Our study aims to assess the benefits and negative implications of REBOA use in adult trauma patients in hemorrhagic shock with severe thoracic or abdominal injuries.
Methods: This retrospective cohort analysis utilized the American College of Surgeons Trauma Quality Improvement Program Participant Use File (ACS-TQIP-PUF) database from 2017 to 2023 to evaluate adult patients with severe isolated thoracic or abdominal trauma undergoing REBOA placement.
Predicting left-without-being-seen in an emergency department as a dynamic risk.

University of Toronto, Rotman School of Management, Canada.
Study Objective: Accurately predicting which Emergency Department (ED) patients are at high risk of leaving without being seen (LWBS) could enable targeted interventions aimed at reducing LWBS rates. Machine Learning (ML) models that dynamically update these risk predictions as patients experience more time waiting were developed and validated, in order to improve the prediction accuracy and correctly identify more patients who LWBS.
Methods: The study was deemed quality improvement by the institutional review board, and collected all patient visits to the ED of a large academic medical campus over 24 months.
