Intravenous Versus Oral Tranexamic Acid In Shoulder Arthroplasty, Tarishi Parmar, Akin Adio, Mohammad Daher, Adam Khan, John Horneff, Joseph A. Abboud

Rothman Institute Papers

PURPOSE: Tranexamic acid (TXA) is used in shoulder arthroplasty to reduce blood loss. While intravenous (IV) TXA is standard, oral TXA offers advantages in cost and administration. This study compares 90-day complications and postoperative laboratory values between IV and oral TXA in total shoulder arthroplasty (TSA).

METHODS: A retrospective cohort study using TriNetX identified adults undergoing primary TSA (2005-2025) receiving TXA on the day of surgery, stratified by route (IV vs. oral). One-to-one propensity score matching was performed. Ninety-day outcomes included transfusion, thromboembolic events, cardiac and renal complications, neurologic events, infection, wound dehiscence, readmissions, emergency department visits, opioid utilization, and …

Non-Tobacco Nicotine Dependence Is Associated With Increased Complications Following Clavicle Open Reduction Internal Fixation, Akin A. Adio, Rahul K. Goyal, Abby Skiena, Mohammad Daher, John G. Horneff, Hafiz F. Kassam, Brian W. Hill, Joseph A. Abboud

Rothman Institute Papers

BACKGROUND: Tobacco dependence is well established to impair bone healing and increase postoperative complications. However, the independent effects of nicotine, separate from combustion-related factors, remain unclear. This study aimed to evaluate the impact of non-tobacco nicotine dependence (NTND) following open reduction and internal fixation (ORIF) of clavicle fractures, including midshaft and lateral fracture subtypes.

METHODS: A retrospective cohort study was performed using a large national database. Patients undergoing ORIF of clavicle fractures were identified using procedural and diagnostic codes. Patients with non-tobacco nicotine dependence (e.g., vaping, patches, or gum) were identified and propensity score matched to (1) patients without nicotine …

Evaluating Normothermic Machine Perfusion For Dcd Liver Transplants: Outcomes, Costs, And Value Implications, Meet S. Patel, Alisha Williams, Kyrillos Ayoub, Noor Kamaladin, Charles S. Day

Medical Student Research Symposium

Background: As liver transplantation expands to include marginal donor organs, technologies such as the TransMedics Organ Care System (OCS) offer the potential to improve graft viability and clinical outcomes. However, limited institution-level evidence exists evaluating the cost-outcomes balance of OCS use in Donation-After-Circulatory-Death (DCD) liver transplantation. This study assesses the clinical, operational, and economic value of OCS implementation within a high-volume transplant center.

Methods: A retrospective cohort analysis was conducted of all DCD liver transplants performed at Henry Ford Hospital from January 2021 to April 2024. Outcomes were compared between traditional cold storage (2021; n=23) and OCS perfusion (2023–2024; n=82). …

Addition Of Prg4 To Optimize The Anti‑Adhesive Properties Of Tissue Barrier Sepraflm®, Ava J. Marks, Khaled A. Elsaid, Ling X. Zhang, Timmy Lin, Janette Baird, Tannin A. Schmidt, Gregory D. Jay

Pharmacy Faculty Articles and Research

Purpose

Postsurgical adhesion remains a significant clinical challenge. Seprafilm^® is widely used as a barrier to reduce adhesion formation, however its efficacy may be inconsistent. Recombinant human proteoglycan-4 (rhPRG4), a surface-active, anti-inflammatory glycoprotein found in synovial fluid inhibits cell and protein adhesion. This study investigated whether coating Seprafilm with rhPRG4 could enhance its anti-adhesive potential.

Methods

Macrophages (J774), human fibroblast-like synoviocytes (HFLS), and melanoma (A375) cells were cultured on tissue culture wells treated with rhPRG4 or bovine submaxillary mucin (BSM) to determine optimal seeding density. Seprafilm sheets were coated with rhPRG4 or BSM (0.78–200 µg/mL). Cell adhesion was quantified …

Given expanding clinical use and variation in technique, a structured mapping of the adult evidence base is warranted.
2. B.     Methodology: This scoping review followed PRISMA-ScR guidance. PubMed and CINAHL were searched, yielding 88 records. After duplicate removal and screening, 18 studies met inclusion criteria. Data were charted on study design, cardioplegia formulation, patient population, myocardial biomarkers, arrhythmias, renal outcomes, transfusion requirements, …

Comparison Of Ventilation Support During Laser Treatment Of Retinopathy Of Prematurity, Jason Peng, Raghav Taneja, Barry N. Wasserman, Krystal Hunter, Vineet Bhandari, Alla Kushnir

Wills Eye Hospital Papers

Highlights: What are the main findings? Preterm infants undergoing ROP laser surgery with routine elective intubation had significantly longer durations of post-operative mechanical ventilation. Routine intubation during this procedure did not improve short-term clinical outcomes, such as overall hospital length of stay or timing of laser intervention in the infant’s life. What are the implications of the main findings? Routine intubation strategies may unnecessarily increase exposure to mechanical ventilation without improving clinical outcomes. Standardization of perioperative intubation practices across hospitals may be needed to optimize respiratory support in this vulnerable population. Objective: To compare respiratory outcomes between infants undergoing retinopathy …

Chulalongkorn Medical Journal

Background: Detecting bone union is a crucial process in treating bone fractures to prevent complications, including implant failure and bone nonunion. Nowadays, there are many methods and new innovative devices for detecting bone union through strain measurements, such as strain gauges, fluid level displacement, contrast media, and frequency changes. There is also a trend toward increasing these methods in the future. However, the patterns of bone healing studied with these methods still do not provide a standard for determining the true bone healing process. The aim of this study is to identify the most appropriate bone healing pattern for …
