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 …

Surgical Outcomes Of Hidradenitis Suppurativa Excision: Factors Impacting Wound Healing Time, Christina Huang, Scott H. Koeneman, Sherry Yang, Sami Tannour

Department of Surgery Faculty Papers

Hidradenitis suppurativa (HS) can be treated surgically to excise recurrent and recalcitrant regions of disease activity. However, surgical outcomes are highly variable depending on closure method, concomitant medical management and area of excision. In this study, we aim to characterise the healing courses from HS excision in a case series. To reduce operator variability, we opted to conduct a case series from a single surgeon. Surgeries conducted from June 2024-December 2025 by surgeon S.T. were included, and the postoperative course was followed until February 2026. Surgical details and postoperative course for 34 sites of HS across 20 patients were analysed. …

Pearson Syndrome: Expanding The Clinical Spectrum Of A Mitochondrial Cytopathy-A Case Report, Alizah Faisal, Hooria Waqas, Hania Masood, Armeen Butt, Saad Rahman, Muhammad Sheraz Hameed, Syed Rafay Hussain Zaidi, Ali Iqbal, Muhammad Usama Naveed

Department of Medicine Faculty Papers

BACKGROUND: Pearson syndrome (PS) is a rare multisystem mitochondrial disorder characterized by single large-scale mitochondrial DNA deletions (SLSMDs). It typically presents in infancy with refractory sideroblastic anemia, exocrine pancreatic insufficiency, and failure to thrive. Due to its heterogeneous manifestations and resemblance to other hematological conditions, early diagnosis remains a clinical challenge.

CASE PRESENTATION: A south asian male infant presented with persistent pancytopenia, severe anemia unresponsive to intravenous and oral iron and multivitamin supplements, exocrine pancreatic insufficiency, failure to thrive, and metabolic acidosis. Born to consanguineous parents, the child had a significant family history of early infant deaths and hematological abnormalities. …

Cryoneurolysis Of Auriculotemporal Nerve For Treatment Of Otalgia, Nikit Patel, Shireen Rabiei, Daniel Moon, Yevgeniya Sergeyenko

Moss-Magee Rehabilitation Papers

Otalgia in adults is often secondary to non-otologic pathology, particularly with normal otoscopic examination. Auriculotemporal neuralgia (ATN) is a rare and overlooked cause of secondary otalgia. We present a case of an Army veteran with chronic right otalgia and dizziness following blast-related mild traumatic brain injury who was initially diagnosed with vestibular migraine. Despite significant improvement in headache symptoms with migraine-directed preventive and abortive treatments, otalgia persisted. Auriculotemporal nerve block produced complete but short-lived pain relief, confirming ATN. Cryoneurolysis of the auriculotemporal nerve resulted in complete resolution of otalgia for 2-3 months after first and second treatments. However, transient worsening …

Wills Eye Hospital Papers

PURPOSE: Leiomyomas are benign smooth muscle tumors that commonly present in the uterus, soft tissue, skin, and gastrointestinal tract but in rare cases can also arise within the eye. Notably, intraocular leiomyomas often show slightly different histopathologic and immunohistochemical features, referred to as mesectodermal morphology, given their presumed neural crest origin. Genetic and cytogenetic alterations of intraocular leiomyomas, as well as their association with various clinical and histopathologic features, have not been previously studied.

METHODS: We identified eight patients diagnosed with intraocular leiomyoma and performed targeted next-generation sequencing, whole transcriptome RNA sequencing, and chromosomal copy number analysis on those with …

What Community Members With Chronic Illness Teach Future Healthcare Professionals In A Longitudinal Interprofessional Education Program: A Focus Group Study, Rachel White, Maria Brucato, Amber King, Anne B. Mitchell, Nethra S. Ankam

Department of Medicine Faculty Papers

INTRODUCTION: Nearly 50% of Americans have at least one chronic illness. Preparing future healthcare providers for interprofessional collaborative practice (IPCP) and person-centred care through community-based interprofessional education (IPE) can improve outcomes for this growing population. Partial programme theories predict that patients' participation as teachers in health professions education contributes to students' development of patient-centredness. Role theory asserts that behaviours are shaped by assigned roles; therefore, community members with chronic illness who assume roles of health mentors in an IPE curriculum are predicted to teach students about their patient experiences. Yet, this teaching outcome and the lessons health mentors teach in …

Dissatisfaction And Residual Symptoms In Younger And Older Adult Patients After Total Knee Arthroplasty, Nicholas Pohl, Parker Brush, Adrian Santana, Sebastian Fras, Eleanor Jenkins, Arjun Saxena

Department of Orthopaedic Surgery Faculty Papers

INTRODUCTION: Total knee arthroplasty (TKA) is an increasingly used treatment option for younger patients with osteoarthritis. Previous research has found only 66% patients < 60 years who underwent TKA postoperatively reported that their knees felt normal. However, the prior studies did not compare underlying causes for dissatisfaction based on age. This study compared the satisfaction and residual symptom rates between patients ages < 60 and ≥60 years and identified specific reasons for their dissatisfaction between the age groups.

METHODS: Patients who underwent unilateral TKA for osteoarthritis from 2014 to 2016 were electronically sent a 15-question survey pertaining to surgery satisfaction. Following patient identification and survey completion, patient demographics, medical history, surgical time, and length of stay were collected through manual review of medical records. Patients who completed surveys were grouped by age (< 60 years or ≥60 years) for analysis.

RESULTS: In total, 1189 ≥ 60-year-old patients and 388 < 60-year-old patients were included. Most patients in both cohorts reported satisfaction with overall knee function (< 60: 68.6%; ≥60: 71.8%; P = 0.175). Fewer < 60-year patients reported normal knee function (66.5% vs. 75.2%; P < 0.001). The most common residual symptom in both cohorts was continued pain.

CONCLUSION: Patients younger than 60 years reported less satisfaction with performing normal activities …

Molecular Inflammatory Expression Profiles Associated With The Frequency Of Pain In Individuals With Sickle Cell Disease, Lana Mucalo Katunaric, Shuang Jia, Ashima Singh, Mark F. Roethle, Julie A. Panepinto, David C. Brousseau, Martin J. Hessner, Amanda M. Brandow

Department of Pediatrics Faculty Papers

Pain is the most common complication of sickle cell disease (SCD). The underlying biology of SCD pain is not well understood, which is a barrier to novel, effective analgesic and preventive therapies. A wide variability in the phenotypic expression of pain exists among individuals with SCD, despite the inheritance of a similar defective hemoglobin gene. This interindividual pain variability further complicates the ability to understand the biology and effectively treat pain. We sought to discover a biological signature comprising differentially expressed genes unique to SCD that could differentiate between individuals with varied pain frequency. We conducted plasma-induced transcription analysis from …

Feasibility And Preliminary Efficacy Of A Lymphedema And Fibrosis Self-Management Program For Head And Neck Cancer Survivors: A Pilot Randomized Controlled Trial, Jie Deng, Barbara Murphy, Lucy Andersen, Erin Mcmenamin, John Lukens, Joy Cohn, Karthik Rajasekaran, Ryan Quinn, Bryan Spinelli, Alexander Lin

Department of Physical Therapy Faculty Papers

OBJECTIVES: Survivors of head and neck cancer (HNC) are at high risk for developing lymphedema and fibrosis (LEF). Once diagnosed with LEF, survivors must engage in a lifelong program of self-care to minimize long-term adverse effects. However, evidence-based LEF self-management (SM) programs are lacking. To fill this void, we developed and pilot-tested a LEF-SM program for HNC survivors.

MATERIALS AND METHODS: The LEF-SM Program was developed using the Information-Motivation-Behavioral Skills model of health behavior change as a framework. The program was pilot tested in a three-group randomized controlled trial evaluating feasibility and preliminary efficacy. Fifty-nine participants were randomized to: Usual …

Computational Medicine Center Faculty Papers

BACKGROUND: Hyams grading is considered prognostic in olfactory neuroblastoma (ONB), but grading criteria are subjective and predate modern classification and surgical approach. We evaluate the application of granular grading criteria to an endoscopic surgery predominant cohort with extended follow-up.

METHODS: 78 ONB patients were identified (1994-2019) with original diagnoses dating to 1979. Original Hyams grade, Modified Hyams grade incorporating more detailed criteria and other histologic features (i.e. divergent differentiation, clear cell/oncocytic change, and spindling) were assessed if feasible, evaluated for distribution by grade and correlated with outcomes.

RESULTS: Original Hyams grade (n = 43) distribution was: I: 4 (9%), II: …

Haaning, Brian J. Sandri, Henry L. Wyneken, William T. Goldsmith, Joshua P. Nixon, Timothy R. Nurkiewicz, Chris H. Wendt, Paul Barach, Janeen H. Trembley, Tammy A. Butterick

College of Population Health Faculty Papers

Military personnel deployed to Iraq and Afghanistan were exposed to emissions from open-air burn pits, where plastics, metals, and medical waste were incinerated. These exposures have been linked to deployment-related respiratory diseases (DRRD) and may also impact neurological health via the lung-brain axis. To investigate molecular mechanisms, adult male rats were exposed to filtered air, naphthalene (a representative volatile organic compound), or a combination of naphthalene and carbon black (surrogate for particulate matter; CBN) via whole-body inhalation (six hours/day, three consecutive days). Lung, brain, and plasma samples were collected 24 h after the final exposure. Pro-inflammatory biomarkers were assessed using …

Department of Neurosurgery Faculty Papers

INTRODUCTION: Flow diverters (FD) are used for the treatment of intracranial aneurysms, by redirecting flow and serving as a scaffold for endothelial coverage of the aneurysm ostium. However, in-stent stenosis has been observed in some patients treated with these devices, the cause of which and the epidemiology remaining elusive. In the current study we aimed to elucidate potential factors leading to higher degree of in-stent stenosis including gender, location, and type of FD.

METHODS: The authors queried their institutional Electronic Health Record (EHR) for all patients undergoing FD for intracranial saccular aneurysms. We excluded cases where an FD was performed …

Department of Surgery Faculty Papers

BACKGROUND: Inguinal hernia repair is one of the most common general surgery operations. Some evidence suggests that female patients are at greater risk of chronic postoperative pain and hernia recurrence. We investigated rates of chronic inguinal pain and recurrence after inguinal hernia repair in both male and female patients using the Abdominal Core Health Quality Collaborative database.

METHODS: The Abdominal Core Health Quality Collaborative database was queried for patients undergoing elective, unilateral inguinal hernia repair who completed 30-day clinical follow-up and baseline and 1-year European Registry for Abdominal Wall Hernias Survey surveys. Both open and minimally invasive cases were included. …

Comparison Of Open And Laparo-Endoscopic Repair Techniques For Patients With Bilateral Inguinal Hernias, Divyansh Agarwal, Tina Bharani, Nora Fullington, Lauren Ott, Kortney Hodgson, Daelyn Mcclain, Kaela Blake, Michael Reinhorn

Department of Surgery Faculty Papers

INTRODUCTION: For primary bilateral inguinal hernias, international guidelines favor a laparoscopic posterior mesh repair due to relatively lower risk of acute and chronic pain, faster recovery, and favorable biomechanical properties compared to open anterior approaches (Lichtenstein, plug and patch, etc.). However, studies comparing open mesh-based bilateral inguinal hernia repairs to bilateral laparoscopic and robotic mesh-based approaches are limited. The Abdominal Core Health Quality Collaborative (ACHQC) registry includes longitudinal data on bilateral inguinal hernia repairs performed via open as well as laparo-endoscopic approaches. We hypothesize that outcomes for bilateral inguinal hernia repair are similar between open and laparo-endoscopic approaches in the …

Department of Medical Oncology Faculty Papers

BACKGROUND: Patients undergoing tyrosine kinase inhibitor (TKI) therapy for chronic myeloid leukemia (CML) often face challenges with adherence, despite the efficacy of the treatment. Theory-guided and evidence-informed interventions addressing psychosocial and adherence barriers are critical for promoting adherence. Using a mixed-method approach, the pilot study developed and evaluated the feasibility and potential impact of an intervention "txt4TKI," to support medication and symptom management among CML patients undergoing TKI therapy.

METHODS: Guided by the Necessity and Concerns framework, the study comprised two phases: Phase 1 involved qualitative patient needs assessment interviews informing intervention design. Phase 2 was a single-arm pilot study …

Physical Activity Measurement Reactivity Among Midlife Adults With Elevated Risk For Cardiovascular Disease: Protocol For Coordinated Analyses Across Six Studies., Kiri Baga, Gabrielle M Salvatore, Iris Bercovitz, Amanda L Folk, Ria Singh, Laura M König, Meghan L Butryn, Jacqueline A Mogle, Danielle Arigo

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Cardiovascular disease (CVD) remains the leading cause of death in the United States, and adults aged 40-60 years with specific health conditions are at particularly elevated risk for developing CVD. Physical activity (PA) is a key cardioprotective behavior and many interventions exist to promote PA in this group. Effective promotion requires accurate assessment of PA behavior; as PA is often estimated by averaging across multiple days, a threat to accurate assessment is measurement reactivity, or an atypical increase in PA behavior at the start of measurement periods that may bias conclusions. Evidence for PA measurement reactivity is equivocal, though …

Development And Validation Of Risk Stratification For Heart Failure After Acute Coronary Syndrome Based On Dynamic S100a8/A9 Levels, Jie Ma, Ke Ma, Jing Chen, Xinying Yang, Fei Gao, Hai Gao, Hui Zhang, Xin-Liang Ma, Jie Du, Ping Li, Yulin Li

Department of Emergency Medicine Faculty Papers

BACKGROUND: The early assessment of heart failure (HF) risk in patients with acute coronary syndrome (ACS) can help reduce mortality. S100A8/A9 is not only rapidly released after myocardial ischemia, but is also involved in reperfusion injury, which is an important predictor of HF after ACS. We attempted to construct a reliable HF risk stratification tool for evaluating patients with ACS after reperfusion therapy based on S100A8/A9 dynamic changes.

METHODS AND RESULTS: This prospective study included 3 independent cohorts of patients with ACS who received reperfusion therapy. The discovery cohort was divided into 2 subgroups: the longitudinal subgroup (n=264) with serum …

Perturbations In Risk/Reward Decision Making And Frontal Cortical Catecholamine Regulation Induced By Mild Traumatic Brain Injury, Christopher P Knapp, Eleni Papadopoulos, Jessica A Loweth, Ramesh Raghupathi, Stan B Floresco, Barry D Waterhouse, Rachel L Navarra

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Mild traumatic brain injury (mTBI) disrupts cognitive processes that influence risk taking behavior. Little is known regarding the effects of repetitive mild injury (rmTBI) or whether these outcomes are sex specific. Risk/reward decision making is mediated by the prefrontal cortex (PFC), which is densely innervated by catecholaminergic fibers. Aberrant PFC catecholamine activity has been documented following TBI and may underlie TBI-induced risky behavior. The present study characterized the effects of rmTBI on risk/reward decision making behavior and catecholamine transmitter regulatory proteins within the PFC. Rats were exposed to sham, single (smTBI), or three closed-head controlled cortical impact (CH-CCI) injuries and …
