Rothman Institute Papers

INTRODUCTION: Tranexamic acid (TXA) effectively reduces blood loss and transfusion requirements in shoulder arthroplasty. However, concerns regarding thromboembolic, neurologic, cardiac, and renal complications have limited its use in medically high-risk patients. This study evaluated temporal trends and the safety of TXA in high-risk patients undergoing total shoulder arthroplasty (TSA).

METHODS: A retrospective cohort study was conducted using TriNetX, identifying patients who underwent shoulder arthroplasty (2012-2025). Patients were stratified by preexisting high-risk conditions, including prior thromboembolism, renal failure, atrial fibrillation, seizure disorders, and visual disturbances. Within each subgroup, patients receiving TXA were propensity score-matched to those who did not. Perioperative TXA …

Department of Family & Community Medicine Faculty Papers

Purpose: We aimed to describe the disease burden of asthma and examine relationships between short-acting beta-2 agonist (SABA) use and asthma exacerbations. Patients and Methods: This retrospective cohort study used geographically diverse Premier Healthcare Database (PHD) and linked insurance claims (10/01/2021-09/30/2022) for US patients aged ≥18 years with a SABA-only prescription and a history of asthma exacerbation within 12 months before index date (the earliest SABA prescription date). Three asthma control groups were defined based on SABA usage: well controlled-low (0–1 prescriptions), not well controlled-medium (2–3 prescriptions), very poorly controlled-high (≥4 prescriptions). Four asthma severity groups were defined using asthma …

The potent sensitizer PPD is considered a key sensitizer in hair dye contact allergy. Modification of its molecular structure to 2-methoxymethyl-p-phenylenediamine (ME-PPD) reduces its skin sensitizing potency. We investigated the usage, behavior, and tolerance profile of ME-PPD-containing professional hair color products in a specifically tailored proactive market surveillance program in hairdresser salons across 5 countries. Hairdressers completed record cards for their clients, which were evaluated at the end of the program. 497 individuals received in total 2461 hair color treatments with ME-PPD-containing hair color. Feedback on compatibility was provided for 194 individuals: 6 individuals reported intolerance reactions, which were assessed …

Kimmel Cancer Center Faculty Papers

BACKGROUND: Older adults with advanced prostate cancer and type 2 diabetes mellitus are underrepresented in trials of androgen receptor pathway inhibitors. This study examined changes in unplanned hospitalization rates in patients receiving androgen receptor pathway inhibitors by type 2 diabetes mellitus status and assessed if unplanned hospitalization varies according to androgen receptor pathway inhibitors.

METHODS: This population-based study of advanced prostate cancer patients aged older than 66 years used Surveillance, Epidemiology, and End Results-Medicare data. Prepost androgen receptor pathway inhibitor initiation changes and androgen receptor pathway inhibitor differences in unplanned hospitalization rates were estimated by adjusted incidence rate ratio with …

Choline-An Essential Nutrient With Health Benefits And A Signaling Molecule, Brianne C. Burns, Jitendra D. Belani, Hailey N. Wittorf, Eugen Brailoiu, G. Cristina Brailoiu

College of Pharmacy Faculty Papers

Choline has been recognized as an essential nutrient involved in various physiological functions critical to human health. Adequate daily intake of choline has been established by the US National Academy of Medicine in 1998, considering choline requirements for different ages, sex differences and physiological states (e.g., pregnancy). By serving as a precursor for acetylcholine and phospholipids, choline is important for cholinergic transmission and the structural integrity of cell membranes. In addition, choline is involved in lipid and cholesterol transport and serves as a methyl donor after oxidation to betaine. Extracellular choline is transported across the cell membrane via various transport …

The Effect Of Tranexamic Acid On Blood Coagulation In Primary Total Hip Arthroplasty Using Rotational Thromboelastometry: A Randomized Controlled Trial, Uzung Yoon, David Beausang, Elia Elia, Marc Torjman, Jeffrey Mojica, James J. Purtill, David Nazarian, P. Maxwell Courtney, Yoogoo Kang

Department of Anesthesiology Faculty Papers

BACKGROUND: Tranexamic acid (TXA), is commonly administered prophylactically to reduce blood loss in patients undergoing total hip arthroplasty (THA). However, its effect has never been studied. We hypothesized that no difference exists in the degree of fibrinolysis and blood loss between patients receiving prophylactic TXA and placebo.

METHODS: This double-blinded randomized-controlled trial included 50 patients undergoing primary THA in 2021-2023. Clinicaltrials.gov (NCT03897621). Rotational-thromboelastometry (ROTEM) were performed to test blood coagulability using non citrated whole blood (NATEM) and blood treated with TXA (T-APTEM). The intervention group received TXA intravenously. The placebo group received 0.9% sodium chloride solution. The primary outcome measure …

A Case Of Turmeric-Induced Hepatotoxicity With Hyperferritinemia, Nina R. Spitofsky, Albert A. Huang, Aria Jalalian, Stefanie Gallagher, Scott Fink

Department of Medicine Faculty Papers

Introduction: We present the first published case of turmeric-associated drug-induced liver injury (DILI) accompanied by significant ferritin elevation. Case Presentation: Our patient, a 59-year-old female with DILI caused by long-term ingestion of oral turmeric supplements, presented with painless jaundice on an annual exam. The patient’s liver function tests exhibited a hepatocellular pattern and hyperferritinemia (>2,000 ng/dL). Additional testing was negative except for heterozygosity for the H63D allele associated with hemochromatosis. A liver biopsy indicated acute hepatitis without fibrosis or stainable iron. Conclusion: Upon discontinuation of the supplement, liver enzymes normalized within a month. This case highlights the potential for …

College of Life Sciences Faculty Papers

A series of fluorinated and non-fluorinated [6]-gingerol, [6]-paradol, [6]-shogaol and ferulate derivatives were synthesized. Testing these analogs in anti-proliferation assays with MCF-7, A549, HCT-116 and HEK-293 cell lines provided insight into the structural features that contribute to the anti-proliferative activity of naturally occurring ginger constituents. In particular, the use of both vinyl and alkyl trifluoromethyl isosteres allowed us to evaluate the structure-activity impact of the enone motif found in shogaols. Our results indicate that enone-containing derivatives have a higher potency, suggesting the conjugated enone motif characteristic of shogaols may be primarily responsible for the anti-cancer activity of the broader natural …

INTRODUCTION: Palovarotene is a retinoic acid receptor gamma agonist that was studied in phase-2 and phase-3 clinical trials for the inhibition of new heterotopic ossification (HO) in fibrodysplasia ossificans progressiva (FOP). Despite numerous setbacks and regulatory delays, palovarotene is now the first approved FOP treatment in the U.S.A., Canada and Australia but remains unapproved in Europe where concerns surrounding the drug and its path to regional market authorization persist.

AREAS COVERED: The developmental history of palovarotene and an overview of the clinical trials and the regulatory approval journey are discussed by global FOP experts.

EXPERT OPINION: While post hoc analyses …

Xiao, Andreina Rojas, Kevin López Romero, Valentina Contreras, Sol Villa Nogueyra, Zulma Sosa, Samantha M. Alvarez, Camila Sánchez Cruz, Ernesto Calderón Martinez

Department of Radiology Faculty Papers

BACKGROUND: The use of beta-blockers in the perioperative period has been widely investigated due to their potential to reduce the risk of major adverse cardiovascular and cerebrovascular events (MACCE) and mortality; yet their overall impact on various postoperative outcomes remains debated. This study constitutes a systematic review and meta-analysis of the impact of beta-blockers on mortality, MI, stroke, and other adverse effects such as hypotension and bradycardia in patients undergoing non-cardiac surgery.

METHODS: A comprehensive systematic review and meta-analysis were conducted according to PRISMA 2020 guidelines. Searches were performed across PubMed, Cochrane, Web of Science, Scopus, EMBASE, and CINAHL databases; …
