Pharmacotherapy For Primary Biliary Cholangitis: An Assessment Of Medication Candidacy And Rates Of Treatment, Nicholas Macdonald, Rebecca Loh, Jonathan Fenkel, David Sass, Dina Halegoua-De Marzio

Division of Gastroenterology and Hepatology Faculty Papers

BACKGROUND: Ursodeoxycholic acid is the preferred first-line therapy for primary biliary cholangitis. Alternative therapies, such as obeticholic acid, are recommended for patients who cannot tolerate ursodeoxycholic acid or who have an inadequate response to ursodeoxycholic acid monotherapy. Prior investigations have suggested that as many as 30% of patients with primary biliary cholangitis may have never received treatment with ursodeoxycholic acid. No prior investigations have examined usage rates of obeticholic acid in the treatment of primary biliary cholangitis.

METHODS: All patients with an ICD-10 diagnosis of primary biliary cholangitis who had any records within the health system were included. A review …

Identifying Opportunities For Prevention Of Adverse Outcomes Following Female Genital Fistula Repair: Protocol For A Mixed-Methods Study In Uganda, Alison El Ayadi, Susan Obore, Fred Kirya, Suellen Miller, Abner Korn, Hadija Nalubwama, John Neuhaus, Monica Getahun, Patrick Eyul, Robert Twine, Erin Andrew, Justus Barageine

Department of Obstetrics and Gynecology Faculty Papers

BACKGROUND: Female genital fistula is a traumatic debilitating injury, frequently caused by prolonged obstructed labor, affecting between 500,000-2 million women in lower-resource settings. Vesicovaginal fistula causes urinary incontinence, and other morbidity may occur during fistula development. Women with fistula are stigmatized, limit social and economic engagement, and experience psychiatric morbidity. Improved surgical access has reduced fistula consequences yet post-repair risks impacting quality of life and well-being include fistula repair breakdown or recurrence and ongoing or changing urine leakage or incontinence. Limited evidence on risk factors contributing to adverse outcomes hinders interventions to mitigate adverse events. This study aims to quantify …

Addressing Burden In Caregivers Of Older Adults With Cancer, Lora Rhodes, Lcsw, Kristine Swartz, Md, Caroline Glavin, Lsw, Charlotte Zuber, Kuang-Yi Wen, Phd

Department of Medical Oncology Posters

Background

Forty-two million adults in the United States are providing unpaid care for a family member or friend over the age of 50. For approximately 2.5 million of these caregivers, cancer is the primary illness or disability of their care recipient (National Alliance for Caregiving and AARP, 2020). As baby boomers continue to age, and the number of cancer survivors continues to increase, the need for informal caregivers will expand exponentially.

While Comprehensive Geriatric Assessment (CGA) is recommended for older patients with cancer and distress screening is recommended for all cancer patients, there are currently no recommendations regarding screening for …

Actin Depolymerization Of Tenocytes Promotes A Tendinosis-Like Gene Expression, Kameron Inguito, Ba, Valerie West, Karl Matthew Ebron, Justin Parreno, Phd

Alpha Omega Alpha Research Symposium Posters

Optimal cellular mechanotransduction is essential for tendon matrix homeostasis. We recently developed an in vivo rat model of tendinosis, where the plantaris tendon are overloaded through ablation of the synergistic Achilles tendon. Using this model we determined that tissue overload disrupts matrix-cell interactions, which results in under-stimulation of tendon cells (tenocytes) (Fig.1)

Using an ex vivo model of tendon stress deprivation by maintaining tail tendon fascicles in floating culture we showed that tenocyte under-stimulation results in destabilization of filamentous (F-)actin (Fig.2). F-actin destabilization coincides with tendinosis-like gene expression: downregulation of tenogenic genes (Col1, Tnc, asma, Scx), upregulation of chondrogenic (Acan, …

Longitudinal Monitoring Of Gait Parameters For Lower Limb Prosthetic Users With Physical Therapy Using Video-Based Gait Analysis, Alisha Agarwal, Bs, Anthony Cimorelli, Cpo, R. James Cotton, Md, Phd

Alpha Omega Alpha Research Symposium Posters

Introduction

Gait training in physical therapy is a common standard of practice for new lower limb prosthetic users. Progress is typically assessed through functional outcome measures such as the 10-meter or 6-minute walk tests1. While these tests measure walking speed and endurance, they fall short of capturing gait quality or quantifying gait parameters which literature shows to be of therapeutic value 2,3. Routine access to quantitative gait assessment could provide clinicians with benchmarks to optimize treatment interventions. Traditional gait analysis systems require specialized equipment making them very resource-intensive and inconvenient to operate. Using human pose estimation techniques, we have developed …

SKMC Student Presentations and Publications

Substance use disorders (SUDs) have an enormous impact on public health. With classic psychedelic-assisted therapies showing initial promise in treating multiple SUDs, it is possible that these treatments will become legally available options for patients with SUDs in the future. This article highlights how classic psychedelic-assisted therapies might be integrated into current clinical practice. We first describe contemporary evidence-based treatments for SUDs and highlight how classic psychedelic-assisted therapies might fit within each treatment. We suggest that classic psychedelic-assisted therapies can be integrated into most mainstream evidence-based SUD treatments that are currently used in clinical settings, indicating broad compatibility of classic …

Acute Brachial Artery Occlusion Following Cisplatin-Based Chemotherapy: Case Report, Abenezer Melaku Tafese, Amanuel Yegnanew Adela, Assefa Getachew Kebede, Aklilu Sinte Tegegn, Elsabeth Tizazu Asare, Munir Awol

Student Papers, Posters & Projects

Thromboembolism is a significant cause of mortality and morbidity in cancer patients. While the link between cancer and venous thrombosis is well known, the recognition of arterial thrombosis as a serious complication of cancer and chemotherapeutic agents is a recent development. One of the chemotherapy agents frequently linked to acute vascular events is cisplatin. We discuss a rare case of cisplatin-related brachial arterial thrombosis in a 50-year-old man who was treated for cholangiocarcinoma with cisplatin and gemcitabine. Although rare, cisplatin-related arterial thrombosis demands careful monitoring, a high index of suspicion, and prompt management to prevent serious complications and mortality.

A Proposal For The Use Of A Fixed Low-Energy Selective Laser Trabeculoplasty For Open Angle Glaucoma, Zachary Sacks, L. Jay Katz, Gus Gazzard, Sarah H. Van Tassel, Eytan Z. Blumenthal, Fabian S. Lerner, Augusto Azuara-Blanco, Gregory John Roy Spooner, Yoram Solberg, Thomas Samuelson, Michael Belkin

Wills Eye Hospital Papers

Selective laser trabeculoplasty (SLT) has been in routine clinical use for over 20 years with millions of patients successfully treated and a low rate of clinically significant complications. The procedure requires the clinician to manually position the laser beam on the trabecular meshwork using a gonioscopy lens and to titrate the SLT laser energy based on the amount of pigmentation in the angle, as well as the observation of small bubbles produced by the laser effect. We propose that SLT energy titration is unnecessary either to achieve intraocular pressure (IOP) reduction or to minimize potential side effects. Ample evidence to …

Two-Pore Channel-2 And Inositol Trisphosphate Receptors Coordinate Ca2+ Signals Between Lysosomes And The Endoplasmic Reticulum, Yu Yuan, Vikas Arige, Ryo Saito, Qianru Mu, Gabriela C. Brailoiu, Gustavo J.S. Pereira, Stephen R. Bolsover, Marco Keller, Franz Bracher, Christian Grimm, Eugen Brailoiu, Jonathan S. Marchant, David I. Yule, Sandip Patel

College of Pharmacy Faculty Papers

Lysosomes and the endoplasmic reticulum (ER) are Ca2+ stores mobilized by the second messengers NAADP and IP3, respectively. Here, we establish Ca2+ signals between the two sources as fundamental building blocks that couple local release to global changes in Ca2+. Cell-wide Ca2+ signals evoked by activation of endogenous NAADP-sensitive channels on lysosomes comprise both local and global components and exhibit a major dependence on ER Ca2+ despite their lysosomal origin. Knockout of ER IP3 receptor channels delays these signals, whereas expression of lysosomal TPC2 channels accelerates them. High-resolution Ca2+ imaging reveals elementary events upon TPC2 opening and signals coupled to …
