Article Abstract
Background: Since Food and Drug Administration approval of transcatheter aortic valve replacement (TAVR) in 2011, advancements in technology and procedural refinements have improved efficiency and safety. By systematically eliminating steps in the original TAVR protocol, we achieved reductions in procedural time, contrast volume, and fluoroscopy time without compromising outcomes.
Methods: Institutional TAVR data (November 2012 to September 2023) were analyzed, focusing on procedural times, contrast volume, radiation exposure, and outcomes. Four protocol modifications were compared: traditional protocol (2012 to 2016), elimination of rotational angiogram (2017 to 2020), elimination of balloon valvuloplasty (2020 to 2022), and elimination of femoral angiogram (2022 to 2023).
Results: Among 1095 TAVR procedures, 88.5% were femoral access, and 86.0% were done under conscious sedation. The mean age of patients was 79.0 ± 8.7 years, with 59% males. Most patients were classified in the Society of Thoracic Surgeons intermediate-risk category (38.4%), followed by prohibitive risk (30.0%), high risk (23.9%), and low risk (7.4%). Average procedural time, contrast volume, and fluoroscopy time were 88.4 ± 38.0 minutes, 73.0 ± 38.8 mL, and 13.8 ± 7.9 minutes, respectively. Adverse events occurred in 15%, with vascular complications (3.7%) being the most common. Mortality was 1.5%, highest in transapical (15%) and lowest in femoral (0.3%). Protocol modifications were associated with significant reductions in procedural time (59.99 ± 15.2 vs. 97.8 ± 33.9 minutes), contrast use (40.1 ± 26.6 vs. 92.9 ± 38.1 mL), fluoroscopy time (8.6 ± 7.4 vs. 18.5 ± 8.5 minutes), and complications (5.5 vs. 25.6%), all < 0.001.
Conclusions: Systematic elimination of procedural steps was associated with reduced procedural time, contrast use, and fluoroscopy time, without compromising patient safety. These refinements may enhance procedural efficiency and patient outcomes.

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.

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.

Background: Autism spectrum disorder (ASD) is more frequently diagnosed in boys than in girls, possibly due to gender-based differences in symptom presentation or referral patterns. This study investigates gender-related variations in symptom severity and clinical presentation among preschool children referred for suspected ASD.
Methods: This study included 125 children (boys: n=103; girls: n=22) aged 2-5 years suspected of having ASD.
