Division of Internal Medicine Faculty Papers & Presentations

Purpose of Review Medetomidine is a veterinary α2-adrenergic agonist that has been an adulterant of illicitly manufactured opioids since 2022. We review its pharmacology, detection, intoxication, withdrawal, and management, and assess why severe withdrawal has emerged in some regions but not others. Recent Findings Medetomidine has spread through North American drug markets yet evades most toxicology testing. Roughly two hundred times more potent than xylazine, with greater α2 selectivity and imidazoline-1 activity, it causes intoxication resembling other α2 agonists: sedation and bradycardia. The dominant clinical problem is withdrawal: autonomic dysregulation, intractable vomiting, and encephalopathy frequently requiring intensive care. Treatment requires …

Department of Obstetrics and Gynecology Faculty Papers

BACKGROUND: Measles is a highly contagious illness capable of causing significant morbidity and mortality, including adverse pregnancy outcomes. Routine screening for measles immunity is not currently recommended during pregnancy. Given the increasing frequency of measles outbreaks nationally and globally, awareness of measles immunity status can influence management of pregnant individuals who incur measles exposures and offer an opportunity for postpartum or preconception vaccination.

OBJECTIVE: We sought to evaluate the cost-effectiveness of universal screening for measles immunity during pregnancy in the United States.

STUDY DESIGN: A decision-analytic model was constructed to evaluate the cost-effectiveness of universal screening for measles immunity during …

Prepregnancy Obesity Versus Excessive Gestational Weight Gain: A Comparative Evaluation Of Adverse Outcomes, Samuel Schultz, David Krantz, Matthew Blitz, Ashley Battarbee, Moti Gulersen

Department of Obstetrics and Gynecology Faculty Papers

Background/Objectives: Obesity and excessive gestational weight gain (EGWG) are known risk factors for adverse outcomes in pregnancy, but the comparative risk is less well defined and increasingly relevant in an era of increasing use of weight loss medications. We aimed to determine whether EGWG was associated with adverse maternal and neonatal outcomes, compared with prepregnancy obesity. Methods: Multicenter retrospective cohort study of pregnant patients who delivered a singleton within a single university health system from 2019–2024. Patients with missing prepregnancy body mass index (BMI) data, BMI < 18.5 kg/m2, or pregestational diabetes were excluded. Logistic regression with propensity score weights and g-computation were used to evaluate if the incidence of several adverse maternal and neonatal outcomes were impacted by prepregnancy obesity and gestational weight gain (GWG). p values were adjusted for multiple comparisons. Results: Among the 129,615 pregnancies included, 28,516 (22.0%) had prepregnancy obesity, 36,943 (28.5%) were overweight prior to pregnancy, and 64,156 (49.5%) had a normal BMI prior to pregnancy. When compared to patients with obesity, patients with normal prepregnancy BMI and EGWG had a lower risk of adverse maternal and neonatal outcomes, including gestational diabetes, gestational hypertension, preeclampsia, eclampsia, cesarean delivery, and postpartum hemorrhage, as well as large and small for gestational age birthweight, stillbirth, neonatal intensive care unit admission, neonatal mechanical ventilation, respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and sepsis. Beneficial effects were attenuated for patients with overweight prepregnancy BMI or for larger EGWG. Conclusions: Lower prepregnancy BMI, even with the potential unintended consequence of EGWG, may be more favorable than untreated prepregnancy obesity with regard to perinatal outcomes.

An Observational Study Of The Effect Of Concomitant Levetiracetam On Apixaban Concentrations In A Hospital Cohort, Chazmyn Riley, Kevin Lam, Cristina Micale, Lynda Thomson, Douglas F. Stickle, Walter K. Kraft

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Despite the lack of evidence of a mechanism-based drug interaction, some professional organizations have advised caution coadministering apixaban and levetiracetam. Eligible patients taking apixaban with or without levetiracetam for any indication for at least 72 h were screened from the electronic medical records. Plasma samples from 77 patients were retrieved from salvaged clinical blood collections. Apixaban minimum and maximum concentrations (Cmin and Cmax) were compared using descriptive statistics in R. While the median Cmin and Cmax appear to be marginally elevated, there were no apparent differences relative to apixaban alone. These findings suggest no apparent interaction of levetiracetam and support …

Characterization Of Mettl3/14-Mediated M6a Modification In Human Transcriptome Using Nanopore Direct Rna Sequencing, Emily Kurtyan, Andrew J. Stein, Kelly J. Abdalla, Zhangerjiao Yuan, Miten Jain, Fadia Ibrahim

Department of Biochemistry and Molecular Biology Faculty Papers

Post-transcriptional RNA modifications modulate diverse aspects of RNA metabolism. N6-methyladenosine (m6A), one of the most abundant internal RNA modifications, is deposited by the core methyltransferase complex, METTL3 and METTL14. Oxford Nanopore Technologies (ONT) platform permits direct, single RNA molecule sequencing while preserving native modifications. However, without rigorous benchmarking, the accuracy and reproducibility of modification detection remain uncertain. Here, we leveraged ONT to comprehensively profile bona fide m6A modifications in cellular RNAs at single-nucleotide resolution by integrating two direct RNA sequencing chemistries (RNA002 and RNA004) with the m6Anet and Dorado modification-detection models. We independently depleted METTL3 and METTL14 in human cells …

Postoperative Complications In Patients With Sickle Cell Disease After Total Shoulder Arthroplasty, Katie Zehner, Gwyneth C. Maloy, John Slevin, Wesley Day, Mitchell K. Ng, Xuan Luo, Jonathan N. Grauer, Arya G. Varthi

Rothman Institute Papers

BACKGROUND: Sickle cell disease (SCD) encompasses a spectrum of genetic hematologic disorders characterized by erythrocyte sickling. Patients may experience musculoskeletal manifestations, such as osteonecrosis, which may warrant consideration for total shoulder arthroplasty (TSA). While prior literature suggests patients with SCD more frequently suffer complications after orthopaedic procedures, this is not well characterized for TSA.

METHODS: Adult TSA patients (older than 18 years) were identified in the 2010 to 2023 PearlDiver M170 database. Patients with SCD were matched 1:4 to patients without SCD based on age, sex, and Elixhauser Comorbidity Index (ECI). Ninety-day postoperative complications, emergency department (ED) visits, and readmissions …

Rothman Institute Papers

INTRODUCTION: Isotretinoin (ITN) is widely prescribed for severe acne in adolescents and young adults, a population where anterior cruciate ligament reconstruction (ACLR) is commonly performed. Long-standing concerns about impaired wound healing have prompted many surgeons to delay procedures, despite limited orthopaedic-specific evidence. This retrospective case series evaluates early postoperative clinical complications in patients with documented ITN exposure undergoing ACLR.

METHODS: We retrospectively reviewed primary ACLR cases from 2015 to 2025 at a multisite orthopaedic practice with documented ITN exposure within 12 months of surgery and at least 3 months of follow-up. ITN exposure was categorized as perioperative (≤10 days), recent …

Mitochondrial Trna-Derived Fragments As Candidate Metastasis-Modifying Rna, Katy L. Swancutt, R. Mckinnon Walsh, Sydney Quijano, Emily Schueddig, Devin C. Koestler, Adam D. Scheid, Tony Vanden Bush, Yi Jing, Isidore Rigoutsos, Danny R. Welch

Computational Medicine Center Faculty Papers

UNLABELLED: How mitochondrial DNA (mtDNA) polymorphisms influence complex phenotypes remains poorly understood. Using mitochondrial-nuclear exchange mice, we previously showed that mtDNA single-nucleotide polymorphisms (SNP) modify metastasis, cardiovascular disease, and epigenetic marks independently of metabolic differences. The only mtDNA SNP correlating with these phenotypes resides in the gene encoding mitochondrial transfer RNA (tRNA)-arginine [mt-tRNAArg (UCG), mt-TR], suggesting a role for non-protein-coding loci. In this study, we identify and preliminarily characterize previously undescribed tRNA-derived fragments (tRF) generated from mt-TRs. Northern blotting revealed distinct tRF that are differentially expressed among mtDNA SNPs, between lung and liver, and between sexes. Surprisingly, small RNA sequencing …
