A Case Report And Evaluation Of Intrauterine Gas Of Unknown Origin, Chrystal Stallworth, Diane Gilbertson, Michele L. Mccarroll, Timothy Kremer Aug 2025

A Case Report And Evaluation Of Intrauterine Gas Of Unknown Origin, Chrystal Stallworth, Diane Gilbertson, Michele L. Mccarroll, Timothy Kremer

HCA Healthcare Journal of Medicine

Introduction

Most reports of intrauterine or endometrial gas have been reported in the setting of underlying gynecologic malignancy or infection. The significance of this case report is to give a presentation of a patient presenting with intrauterine gas who subsequently was identified as having neither an infectious nor malignant cause for such a finding.

Case Presentation

The patient is a 56-year-old postmenopausal woman who presented with “hip pain” and was found to have incidental intrauterine gas on a pelvic computed tomography. She underwent in-office and outpatient hysteroscopies with resection of a submucosal fibroid. Her final pathology was returned as benign, …

Recurrent, Acute Limb Ischemia Secondary To Arterial Thrombosis: A Devastating Complication In The Setting Of Severe Covid-19 Infection, Shaikh Afaq, Kyle S. Strouse, Sini Saju, Olugbenga Oyesanmi, Mohamad Eid, Salman Muddassir

HCA Healthcare Journal of Medicine

Background

COVID-19 infection, particularly with the Delta variant, has been associated with a heightened risk of thromboembolic events due to a profound hypercoagulable state. While venous thrombosis is more commonly reported, arterial thrombosis—including acute limb ischemia—has emerged as a serious complication with significant morbidity and mortality.

Case Presentation

We report the case of a 53-year-old man with severe COVID-19 pneumonia who developed recurrent acute limb ischemia secondary to an aortic mural thrombus. Despite therapeutic anticoagulation and multiple surgical interventions—including thrombectomy, angioplasty, and stenting—the patient experienced repeated episodes of arterial thrombosis. His clinical course was further complicated by pneumothorax and hemothorax, …


Dynamics And Malleability Of Plant Dna Methylation During Abiotic Stresses, Niraj Lodhi, Rakesh Srivastava Aug 2025

Dynamics And Malleability Of Plant Dna Methylation During Abiotic Stresses, Niraj Lodhi, Rakesh Srivastava

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Epigenetic regulation, particularly DNA methylation, plays a crucial role in plant adaptation to environmental stresses by modulating gene expression without altering the underlying DNA sequence. In response to major abiotic stresses such as salinity, drought, heat, cold, and heavy metal toxicity, plants undergo dynamic changes in DNA methylation patterns. These modifications are orchestrated by DNA methyltransferases and demethylases with variations depending on plant species, genetic background, and ontogenic phase. DNA methylation affects the expression of key genes involved in cellular, physiological, and metabolic processes essential for stress tolerance. Furthermore, it contributes to the establishment of stress memory, which can be …

Despite the clinical use of anti-vascular endothelial growth factor (VEGF) antibodies (AVAs) in cancer therapy, resistance frequently develops, leading to disease progression. To address this, we identify a previously unknown role for breast cancer type 1 susceptibility protein (BRCA1)-associated RING domain 1 (BARD1) in modulating AVA sensitivity. Epigenetic modulation-via global and targeted DNA methylation-reveals BARD1 as a key regulator of angiogenesis. Sequential treatment with azacytidine overcomes AVA resistance in vivo. To enable precise epigenetic reactivation, we develop a liposomal CRISPR-deactivated Cas9 (dCas9)-TET1 system guided by BARD1-targeting single-guide RNAs (sgRNAs). This platform achieves CpG-specific demethylation of the BARD1 promoter, restores expression, …

Ras-Membrane Interaction And Oligomerization: There Is More Than Meets The Eye, Abraham C Sianoya, Vijay K Bhardwaj, Alemayehu A Gorfe

Faculty, Staff and Student Publications

Membrane association is fundamental to Rat sarcoma (RAS) function, driving both its physiologic signaling and oncogenic transformation. This review consolidates recent advances in the study of RAS-membrane interactions, emphasizing the molecular mechanisms underlying its membrane engagement and oligomerization. We first discuss the roles of RAS lipid modification and conformational diversity of its intrinsically disordered C-terminus in these processes, and we then examine the debate surrounding RAS dimerization and its potential role in the formation of higher-order oligomers. By integrating emerging insights into these issues, we offer our own perspectives on the driving forces of RAS oligomerization and propose potential new …

New Onset Heart Failure Of Sodium-Glucose Cotransporter 2 (Sglt2) Inhibitors In Patients With End-Stage Renal Disease (Esrd) And Dialysis, Daiwik Munjwani, Amin Yehya

Cardiovascular Research Symposium

Introduction: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have demonstrated cardioprotective and renoprotective benefits in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD). However, the effects of these agents in patients with end-stage renal disease (ESRD) or on dialysis remain underexplored, as previous clinical trials often excluded this population. With the recent removal of ESRD as a contraindication by the U.S. Food and Drug Administration, understanding the cardiovascular risks of SGLT2 inhibitors in this group is imperative. This study aimed to assess the incidence of new onset heart failure (HF), including HF with reduced ejection fraction (HFrEF) and …

Using Atrial Pacing Trials After Tavr To Assess Conduction Abnormalities And Predict Need For Pacemaker Implantation, Hemish M. Philip, Matthew R. Summers, Shirish R. Yasa, Hasani Amir, Daiwik P. Munjwani, Thomas A. Cook, Matthew G. Jackson

Cardiovascular Research Symposium

Abstract:

Background: Transcatheter Aortic Valve Replacement (TAVR) is the standard of care for many patients with severe aortic stenosis who cannot undergo surgical intervention. However, conduction disturbances remain a frequent complication, particularly with self-expanding valves. This often leads to permanent pacemaker implantation (PPI). At Sentara Heart Hospital, atrial pacing at 140 bpm is standard practice during TAVR to assess AV conduction.

Objective: This study aims to evaluate whether preserved 1:1 atrioventricular (AV) conduction during routine atrial pacing at 140 bpm after self-expanding TAVR predicts a low likelihood of requiring PPI, thus yielding a high negative predictive value (NPV).

Methods: We …

Development Of Overt Hypo-Attenuated Leaflet Thickening Following Transcatheter Aortic Valve Replacement, Stephonda Lewis, Hemish M. Philip, Matthew Summers

Cardiovascular Research Symposium

Background: Transcatheter aortic valve replacement (TAVR) is a cornerstone therapy for severe aortic stenosis. Up to one-third of patients develop hypoattenuated leaflet thickening (HALT) within the first year post-TAVR. HALT, a form of leaflet thrombosis, can progress to leaflet immobility and structural deterioration. Despite its significance, no unified approach exists for screening or management of HALT after TAVR.

Case Presentation: A 64-year-old woman presented with shortness of breath on exertion. Exam revealed a 3/6 systolic murmur, and echocardiogram confirmed severe aortic stenosis. She underwent TAVR with resolution of symptoms and was discharged on clopidogrel (Plavix) as single antiplatelet therapy. Two …


Novel Guidewire Technique For Paravalvular Leak Repair Following Tavr: A Case Report, Daiwik Munjwani, Bharadwaj Chintalapati, Casey Barry, Matthew R. Summers Aug 2025

Novel Guidewire Technique For Paravalvular Leak Repair Following Tavr: A Case Report, Daiwik Munjwani, Bharadwaj Chintalapati, Casey Barry, Matthew R. Summers

Cardiovascular Research Symposium

Background:

Paravalvular leak (PVL) is a recognized complication following transcatheter aortic valve replacement (TAVR), associated with increased mortality, heart failure symptoms, and hemolytic anemia. Standard percutaneous PVL closure relies on crossing the defect with a 0.035-inch hydrophilic guidewire, followed by exchange for a stiffer wire to enable device delivery. However, traversing the defect can be technically challenging due to decreased maneuverability of the guidewire. We report a case of PVL repair using a modified 0.014-inch polymer-jacketed coronary guidewire and aspiration guidewire strategy that facilitated stable device deployment and complete leak closure.

Case Presentation and Management:

An 86-year-old woman with prior …

Vcd-Induced Model Of Menopause To Study Effects Of Sleep Fragmentation On Atherogenesis, Sarah Shackelford B.S, Alina Moriarty M.S., Basudha Habisyasi M.S., Kathleen Coleman B.S., Pavla Brachova Phd, Diane Duffy Phd, Elena Galkina Phd

Cardiovascular Research Symposium

Introduction: Atherosclerosis is a chronic disease characterized by plaque buildup within arteries, leading to cardiovascular diseases. Sleep fragmentation (SF), defined as less than seven hours of uninterrupted sleep, is a recognized risk factor and is commonly observed in menopausal women. Menopause causes a decline in estrogen and ovarian follicles, resulting in the loss of estrogen’s protective anti-atherogenic effects. SF exacerbates atherosclerosis by promoting oxidative stress and inflammation. Since SF contributes to atherosclerosis, and menopausal women are particularly affected by disturbed sleep, we aim to examine how menopause affects atherogenesis in the conditions of disturbed sleep.

Methods: We used the 4-vinylcyclohexene …

Hiv-1 Controllers Possess A Unique Cd8+ T Cell Activation Phenotype And Loss Of Control Is Associated With Increased Expression Of Exhaustion Markers, Amber D. Jones, Zachary Capriotti, Erin Santos, Angel Lin, Rachel Van Duyne, Stephen Smith, Zachary Klase

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

BACKGROUND: HIV-1 controllers are a rare population of individuals that exhibit spontaneous control of HIV-1 infection without antiretroviral therapy. Understanding the mechanisms by which HIV-1 controllers maintain and eventually lose this ability would be highly valuable in HIV-1 cure or vaccine research. Previous work revealed the ability of CD8+ T cells isolated from HIV-1 controllers to suppress HIV-1 replication in matched CD4+ T cells and PBMCs ex vivo and suggested the loss of control may be tied to CD8+ T cell exhaustion.

RESULTS: We explored whether CD8+ T cell exhaustion plays a role in the maintenance and loss of control …

Background/objectives: High-quality prognostic communication in pediatric oncology is essential to support informed decision making, foster trust, and honor goals of care. While families differ in their preferences for how prognosis is discussed, clinicians often rely on assumptions rather than directly eliciting these preferences, risking misalignment and distress. To address this gap, we aimed to characterize patient, parent, and oncologist perspectives on key variables, experiences, and circumstances that influence their preferences for prognostic communication.

Methods: Semi-structured interviews were conducted with 85 participants (25 patients aged 12-25, 40 parents, and 20 oncologists) to elicit their preferences for prognostic communication and the reasons …

Patients with myeloid neoplasms with loss-of-function TP53 mutations and erythroid differentiation have poor outcomes, and a better understanding of disease biology is required. Upregulation of interferon-γ (IFN-γ) signaling has been associated with acute myeloid leukemia (AML) progression, selection of TP53 mutated clones and chemotherapy resistance, but its drivers remain unclear. In this study, we found that the surface receptor C-C motif chemokine receptor-like 2 (CCRL2) is overexpressed in AML with erythroid differentiation and TP53 mutations compared to other AML subtypes and healthy hematopoietic cells. CCRL2 knockout (KO) suppressed erythroleukemia growth in vitro and in vivo. Further proteomics and transcriptomics analysis …

Introduction: Endovascular thrombectomy (EVT) is an effective treatment for basilar artery occlusion (BAO) stroke in select patients. While there is a growing body of literature suggesting that advanced imaging modalities such as computed tomography perfusion (CTP) and magnetic resonance (MR) may not be necessary for selecting anterior circulation large vessel occlusion stroke patients for EVT, whether advanced imaging may be superior to conventional imaging (non-contrast CT and CT angiography) in identifying good treatment candidates among BAO patients is less clear.

Patients and methods: This was a multicenter retrospective cohort study of BAO EVT patients treated from 2013 to 2022 in …

Breast cancer is the most frequently diagnosed cancer globally and the second leading cause of cancer-related deaths in American women. Triple-negative breast cancer (TNBC) lacks estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. Thus, fewer targeting therapies are available for this most aggressive subtype. The A Disintegrin and Metalloproteinase (ADAM) family plays a vital role in cancer pathophysiology. Previous studies focused on single ADAM members. However, none of these have entered into the clinical arena as diagnostics or therapeutics for breast cancer. In this study, we demonstrate the upregulation of a panel of ADAM members in TNBC, …

Pediatrics in Practice: A CME Podcast

In this episode, we’re joined by Jairrah Godsil, Occupational Therapist at Children’s Mercy, to explore the often misunderstood topic of lip ties in infants. Jairrah shares how lip ties can impact feeding, oral motor development, and long-term function—and what pediatricians should look for during early assessments. We’ll also discuss the importance of a multidisciplinary approach, the role of occupational therapy in treatment, and how to navigate the balance between anatomical structure and functional impact. Whether you’re seeing infants in your clinic or collaborating with feeding specialists, this conversation offers practical insights you won’t want to miss.
