Sustained Supraventricular Tachycardia While In Active Phase Labor, Austin Gold, Mona Sadek

HCA Healthcare Journal of Medicine

Background

Supraventricular tachycardia (SVT) is one of the most common tachyarrhythmias found in young women, and SVT can be exacerbated by pregnancy. The symptoms associated with SVT frequently overlap with physiologic changes and symptoms of pregnancy which can lead to delayed or missed diagnosis.

Case Presentation

We describe the presentation and the acute management of a patient who had sustained SVT that developed during the active phase of labor. We then detail the varying management approaches of SVT in pregnancy and labor as well as refractory management options. Maternal monitoring will also be discussed as this case shows how an …

Simple Summary: There is considerable evidence to suggest that frequent ejaculation reduces the risk of prostate cancer. The more frequently ejaculation occurs without risky sexual behavior, the lower the risk of prostate cancer. The mechanisms regulating the reduction in PCa risk associated with frequent ejaculations are attributed to the suppression of the sympathetic nervous system, resulting in a relief of tension and a slowing of the division of prostate epithelial cells. It is suggested that ejaculation frequency affects gene expression in prostate tissue and subsequently influences the susceptibility of the tissue to tumor formation, leading to a reduction in the …

Cerebral arteriovenous malformations (AVMs) are congenital vascular anomalies that can lead to severe complications, including hemorrhage and neurological deficits. This study compares the outcomes of microsurgical resection and stereotactic radiosurgery (SRS) for SM grade I and II AVMs. Out of a large multicenter registry, we identified 180 matched patients with SM grade I and II AVMs treated with either microsurgical resection or SRS between 2010 and 2023. The primary outcomes were AVM obliteration rates and complications; secondary outcomes included neurological status and functional outcomes measured by the modified Rankin Scale (mRS). Propensity score matching (PSM) was utilized to ensure comparability …

Alcohol And Cannabis Use For Pain Management: Translational Findings Of Relative Risks, Benefits, And Interactions, Sumin Lee, Scott Edwards

School of Medicine Faculty Publications

Chronic pain affects over 20% of the global population and contributes to the vast burden of psychiatric illness. While effective treatments for chronic pain remain limited, both alcohol and cannabis have been used for centuries to manage pain and closely associated negative affective symptoms. However, persistent misuse of alcohol and/or cannabis in such a negative reinforcement fashion is hypothesized to increase the risk of severity of substance use disorders (SUDs). The current review describes neurobiological evidence for the analgesic efficacy of alcohol and primary cannabis constituents and how use or co-use of these substances may influence SUD risk.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced coronavirus disease 2019 (COVID-19) pandemic has challenged the current understanding of the complement cascade mechanisms of host immune responses during infection-induced nonresolvable lung disease. While the complement system is involved in opsonization and phagocytosis of the invading pathogens, uncontrolled complement activation also leads to aberrant autophagic response and tissue damage. Our recent study revealed unique pathologic and fibrotic signature genes associated with epithelial bronchiolization in the lung tissues of patients with nonresolvable COVID-19 (NR-COVID-19) requiring lung transplantation. However, there is a knowledge gap if complement components are modulated to contribute to tissue …

Annual influenza vaccination is recommended for all persons aged ≥6 months in the United States. Interim influenza vaccine effectiveness (VE) was calculated among patients with acute respiratory illness–associated outpatient visits and hospitalizations from four VE networks during the 2024–25 influenza season (October 2024–February 2025). Among children and adolescents aged <18 years, VE against any influenza was 32%, 59%, and 60% in the outpatient setting in three networks, and against influenza-associated hospitalization was 63% and 78% in two networks. Among adults aged ≥18 years, VE in the outpatient setting was 36% and 54% in two networks and was 41% and 55% against hospitalization in two networks. Preliminary estimates indicate that receipt of the 2024–2025 influenza vaccine reduced the likelihood of medically attended influenza and influenza-associated hospitalization. CDC recommends annual receipt of an age-appropriate influenza vaccine by all eligible persons aged ≥6 months as long as influenza viruses continue to circulate locally.

SKMC Student Presentations and Publications

BACKGROUND: Despite advancements in lung transplantation (LT), infection remains a major cause of morbidity and mortality following LT. We examined trends in hospitalizations for infection in the first year after LT.

METHODS: We identified adult LT recipients in the United States (March 1, 2018-March 9, 2023) using the Organ Procurement and Transplantation Network database. We categorized transplants into 3 eras to account for the Composite Allocation Score allocation policy change and coronavirus disease 2019: March 2018 to March 2020, March 2020 to March 2022, and March 2022 to March 9, 2023. One-year post-LT survival was compared using Kaplan-Meier survival analysis …

A Review Of Gut Failure As A Cause And Consequence Of Critical Illness, Danielle E. Soranno, Craig M. Coopersmith, Jessica F. Brinkworth, Faith N. F. Factora, Julia H. Muntean, Monty G. Mythen, Jacob Raphael, Andrew D. Shaw, Vidula Vachharajani, Jeannette S. Messer

Department of Anesthesiology Faculty Papers

In critical illness, all elements of gut function are perturbed. Dysbiosis develops as the gut microbial community loses taxonomic diversity and new virulence factors appear. Intestinal permeability increases, allowing for translocation of bacteria and/or bacterial products. Epithelial function is altered at a cellular level and homeostasis of the epithelial monolayer is compromised by increased intestinal epithelial cell death and decreased proliferation. Gut immunity is impaired with simultaneous activation of maladaptive pro- and anti-inflammatory signals leading to both tissue damage and susceptibility to infections. Additionally, splanchnic vasoconstriction leads to decreased blood flow with local ischemic changes. Together, these interrelated elements of …

A Review Of Racial Differences And Disparities In Ecg, Jianwei Zheng, Chizobam Ani, Islam Abudayyeh, Yunfan Zheng, Cyril Rakovski, Ehsan Yaghmaei, Omolola Ogunyemi

Mathematics, Physics, and Computer Science Faculty Articles and Research

The electrocardiogram (ECG) is a widely used, non-invasive tool for diagnosing a range of cardiovascular conditions, including arrhythmia and heart disease-related structural changes. Despite its critical role in clinical care, racial and ethnic differences in ECG readings are often underexplored or inadequately addressed in research. Variations in key ECG parameters, such as PR interval, QRS duration, QT interval, and T-wave morphology, have been noted across different racial groups. However, the limited research in this area has hindered the development of diagnostic criteria that account for these differences, potentially contributing to healthcare disparities, as ECG interpretation algorithms largely developed from major …

Post-surgical spinal infection occurs in up to 20 % of patients, despite aggressive peri-operative antibiotic treatments. To improve prophylaxis, we have designed and evaluated an ultrasound-activated prophylactic antibiotic release system to combat post-surgical bacterial survival. Polylactic acid (PLA) clips (1 cm³) were 3D-printed with an interior reservoir (0.8 cm³) for carrying drug payload, specifically vancomycin (VAN). Under IACUC approval, clips were surgically implanted into the spines of sheep (n = 9) and swine (n = 2) by removing the spinous process at several levels of the lumbar spine. In the sheep, clips were insonated and the …

2′-Fucosyllactose Inhibits Human Norovirus Replication In Human Intestinal Enteroids, Ketki Patil, B Vijayalakshmi Ayyar, Nicole M Hayes, Frederick H Neill, Lars Bode, Mary K Estes, Robert L Atmar, Sasirekha Ramani

Faculty, Staff and Students Publications

Human noroviruses (HuNoVs) are the leading cause of acute gastroenteritis worldwide. Currently, there are no targeted antivirals for the treatment of HuNoV infection. Histo-blood group antigens (HBGAs) on the intestinal epithelium are cellular attachment factors for HuNoVs; molecules that block the binding of HuNoVs to HBGAs thus have the potential to be developed as antivirals. Human milk oligosaccharides (HMOs) are glycans in human milk with structures analogous to HBGAs. HMOs have been shown to act as decoy receptors to prevent the attachment of multiple enteric pathogens to host cells. Previous X-ray crystallography studies have demonstrated the binding of HMO 2′-fucosyllactose …

Loss Of Mucin 2 And Mhc Ii Molecules Causes Rare Resistance To Murine Rv Infection, Carolyn Bomidi, Faith M Sawyer, Noah Shroyer, Margaret Conner, Mary K Estes, Sarah E Blutt

Faculty, Staff and Students Publications

Enteric pathogen rotavirus (RV) primarily infects mature enterocytes at the tips of the intestinal villi; however, the role of secretory Paneth and goblet cells in RV pathogenesis remains unappreciated. Atoh1 knockout mice (Atoh1cKO) were used to conditionally delete Paneth, goblet, and enteroendocrine cells in the epithelium to investigate the role of secretory cells in RV infection. Unexpectedly, the number of infected enterocytes and the amount of RV shedding in the stool were greatly decreased following secretory cell deletion. Resistance to RV infection persisted for 7 days after virus inoculation, and Atoh1 knockout mice co-housed with infected wild-type mice were uninfected, …

Bloom: Behavioral Learning And Outcome Observation In Microbes, Sean Sarwar Haque, Luke Compton Wharton, Ming Lin, Razvan Voicu

Symposium of Student Scholars

Understanding how pathogens respond to physical changes in their environment is crucial for developing effective treatments and preventative measures. Current research often relies on static models or experimental data that either fail to capture the dynamic interactions within cellular environments or are not generalizable to other types of pathogens. This project aims to address this gap by creating a comprehensive cell simulation that models pathogens and their response to chemical, physical, and physiological changes. The proposed solution is a simulation that integrates biological data and computational modeling to replicate the behavior of pathogens in real time as they are affected …

The Impact Of Diabetes On Neurovascular Integrity: A Special Focus On Pericytes And Endothelin-1, Mia Edgerton

MUSC Theses and Dissertations

Diabetes increases the risk of stroke and Vascular Contributions to Cognitive Impairment and Dementia (VCID). Diabetes also dysregulates the endothelin (ET) system. ET-1-mediated constriction of brain microvascular pericytes (BMVPCs) has been shown to contribute to brain hypoperfusion. However, there is a loss of BMVPCs in VCID, but underlying mechanisms of pericyte degeneration are poorly studied. ETA receptor activation can instigate phenotypical changes and cellular senescence in endothelial cells. . There is also emerging evidence that ETB receptor agonism improves outcomes in patients with cerebral ischemic stroke, but long-term effects, especially in diabetes, are unknown. Therefore, this study aimed to determine …

Leukapheresis is a potentially life-saving therapy for children with symptomatic hyperleukocytosis. However, the standard centrifugation-based approach exposes pediatric patients to significant complications due to its large extracorporeal volume, high flow rates, and considerable platelet loss. Here, we tested whether performing cell separation with a high-throughput microfluidic technology could alleviate these limitations. In vitro, our microfluidic devices removed ~85% of large leukocytes and ~90% of spiked leukemic blasts from undiluted human whole blood, while minimizing platelet losses. Multiplexed devices connected in parallel allowed for faster, clinically relevant flow rates in vitro with no difference in leukocyte collection efficiency. When connected to …

Kimmel Cancer Center Faculty Papers

Purpose: Current treatment guidelines strongly support the use of antiresorptive therapy in patients with newly diagnosed multiple myeloma (NDMM) with the goal of preventing skeletal related events (SRE). Despite these concrete, data-driven recommendations, the impact of delays in antiresorptive initiation in NDMM patients is understudied. Through a multicenter retrospective study, we examined the impact of delays in antiresorptive initiation on the rates of SREs. We furthered our exploration of this topic in a separate retrospective analysis with a focus on reasons for delays in antiresorptive therapy initiation. Methods: Electronic health records from two large academic institutions were used to identify …

Zika Virus Ns1 Drives Tunneling Nanotube Formation For Mitochondrial Transfer And Stealth Transmission In Trophoblasts, Rafael T Michita, Long B Tran, Steven J Bark, Deepak Kumar, Shay A Toner, Joyce Jose, Indira U Mysorekar, Anoop Narayanan

Faculty, Staff and Students Publications

Zika virus (ZIKV) is unique among orthoflaviviruses in its vertical transmission capacity in humans, yet the underlying mechanisms remain incompletely understood. Here, we show that ZIKV induces tunneling nanotubes (TNTs) in placental trophoblasts which facilitate transfer of viral particles, proteins, mitochondria, and RNA to neighboring uninfected cells. TNT formation is driven exclusively via ZIKV non-structural protein 1 (NS1). Specifically, the N-terminal 1-50 amino acids of membrane-bound ZIKV NS1 are necessary for triggering TNT formation in host cells. Trophoblasts infected with TNT-deficient ZIKV
