Percutaneous Closure Of Ventricular Septal Rupture After Myocardial Infarction:, Thomas A. Cook, Simone K. Schumaecker, Anjani Patibandla, Nicholas J. Valle, Matthew R. Summers

Department of Medicine Faculty Publications

BACKGROUND: Ventricular septal rupture (VSR) following acute myocardial infarction is a rare but deadly complication with mortality rates exceeding 90% when left untreated. Coronary ischaemia leads to myocardial necrosis and friability resulting in septal rupture, most commonly 3-5 days post-infarction. The sudden development of a left-to-right shunt causes volume overload in the right ventricle, pulmonary vasculature, and left atrium, precipitating biventricular failure, and cardiogenic shock. Management requires careful consideration of timing and modality of closure along with stabilization with mechanical circulatory support in severe cases.

CASE SUMMARY: A 65-year-old female presented with anterior ST-segment elevation myocardial infarction complicated by VSR …

Department of Medicine Faculty Publications

Background and AIMS

Fully covered self-expandable metal stents (FcSEMSs) have become the mainstay of treatment for a variety of biliary pathologies. However, FcSEMSs have been associated with a greater rate of stent migration than other types of stents. A technique of anchoring double-pigtail plastic stents (DPPSs) has been proposed to minimize migration of biliary FcSEMSs. Herein, we evaluated the efficacy of anchoring DPPSs among patients treated with biliary FcSEMSs.

Methods

We performed a systematic review using PubMed, EMBASE, and Web of Science from database inception through August 2023. Full-text articles comparing FcSEMSs with or without anchoring DPPSs were included. We …

Melissa Peet, Kristen Kelley, Ryan Johnson, Vivek Agrahari, Maria Mendoza, Yi Pan, Walid Heneine, Meredith R. Clark, J. Gerardo García Lerma, Gustavo F. Doncel, James W. Smith

CONRAD Publications

On-demand topical inserts for HIV prevention may be a good option for people who have a low frequency of sexual activity. We recently demonstrated in a preclinical macaque model that rectal application of inserts containing tenofovir alafenamide fumarate (TAF) and elvitegravir (EVG) conferred protection against SHIV infection (93% efficacy) when applied as pre-exposure prophylaxis 4 hours before SHIV exposure. Here, we show that the same inserts provide significant postexposure protection (82.9% efficacy) when applied 4 hours after SHIV exposure. Our findings further support the ongoing clinical development of TAF/EVG inserts for on-demand HIV prevention.

Electrochemical Sensors For In Situ Monitoring Of Reactive Species During Cold Atmospheric Plasma-Based Therapies, Jonathan Thomas, Suneel Kumar, Gagana Karkada, Julia Sutter, Kristina Pattison, Jason Rainone, Dhruv Patel, Shashank Madhavan, Fred Krebs, Francois Berthiaume, Vandana Miller, Katharina Stapelmann

Kimmel Cancer Center Faculty Papers

Cold atmospheric pressure plasma (CAP) is emerging as a clinically relevant therapy for dermatological conditions such as actinic keratosis, warts, and chronic wounds. However, these therapies lack strategies to monitor CAP delivery in situ and to ensure delivery of an effective CAP dose without unwanted toxicity. CAP acts as a therapeutic agent in these biomedical applications primarily (but not solely) through reactive oxygen and nitrogen species (RONS) generated at transiently high local concentrations. Here we demonstrate the use of bio-electrochemical sensors capable of real-time measurements of key CAP RONS: hydrogen peroxide and oxidation-reduction-potential (ORP). In in vitro scratch assays and …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …
