Rare Atypical Presentation Of Ogilvie Syndrome In A Hispanic Man, Aramide Mikhail Tijani, Semenawit B. Burka, Nazish Khan, Fatimah Oluwakemi Bello

Research Symposium

Background: Ogilvie syndrome (OS) also known as acute pseudo-obstruction of the colon is a bowel motility disorder characterized by features of intestinal obstruction in the absence of an anatomical or mechanical cause. Typical presentation is with abdominal distension but atypical and more rare presenting features have also been reported including respiratory distress. Thus, we present the first case of Ogilvie syndrome presenting with respiratory distress in a Hispanic man.

Case Presentation: A 71-year-old gentleman with a history of diabetes mellitus, functional quadriplegia and other comorbidities was brought to the ED via EMS on account of altered metal status and constipation …

Cardioprotective Effects Of Naltrindole In Rat Myocardial Ischemia/Reperfusion Injury Are Concentration-Dependent, Logan Clair, Tanoh Boakye, James Ramsarran, Zinya Talukder, Nikola Maricic, Ukoha Kalu, Juliet Melnik, Tameka Dean, Qian Chen, Robert J. Barsotti, Lindon H. Young

Myocardial infarction remains a major cause of mortality and morbidity globally and infarct size is a major determinant of prognosis. Early and successful restoration of myocardial reperfusion is effective to reduce final infarct size and improve clinical outcomes. However, reperfusion induces further damage to the myocardium, hence the need for adjunctive therapy. Cardioprotective therapies to limit myocardial hypercontracture that occurs during prolonged ischemia and is associated with ischemia-reperfusion (I/R) injury are an important clinical goal. Previously, naltrindole (NTI, 5µM), when given prior to ischemia, exerted cardioprotective effects in ex-vivo, rat myocardial I/R, in part, by attenuating ischemic hypercontracture that occurred …

Dual Myristic Acid And Trans-Activator Of Transcription Conjugation Of Pkc Beta Ii Peptide Inhibitor Augments Cellular Delivery To Counteract Myocardial Ischemia/Reperfusion Injury, James Ramsarran, Logan Clair, Taurai Augustin, Zinya Talukder, Emily Andrews, Tameka Dean, Qian Chen, Robert J. Barsotti, Lindon H. Young

Research Day

INTRODUCTION: Dual conjugation of PKC Beta II peptide inhibitor (PKCβII-) with myristic acid (myr) and trans-activator of transcription (Tat) (Myr-Tat-CC-SLNPEWNET [myr-Tat-PKCβII-]) has been shown to enhance intracellular delivery and attenuate myocardial ischemia/reperfusion (I/R) injury in an ex-vivo rat model. Previously, myr-Tat-PKCβII- demonstrated significant cardioprotective effects from 100nM to the 1pM concentration.

OBJECTIVES: The lowest concentration at which myr-Tat-PKCβII- is still cardioprotective has yet to be determined; this study investigates the 100fM concentration.

METHODS: Isolated rat hearts from anesthetized male SD rats (275g to 300g) underwent global I(30-min)/R(50-min). Cardiac function was recorded via a pressure transducer. Treatments were infused during the …

Bilateral Lower Extremity Ischemia Following Cardiac Catheterization, Moses Avedikian, Alan Lucerna, Trent Malcolm

Rowan-Virtua Research Day

Acute limb ischemia is a rare yet limb-threatening presentation where rapid diagnosis and intervention is warranted. Bilateral lower extremity ischemia can be a rare complication following procedures, such as a cardiac catheterization with access obtained in the groin. We describe a case of a 79-year-old female who presented with bilateral lower extremity ischemia following a cardiac catheterization 2 weeks prior. The patient underwent CT angiography, which demonstrated occlusion with no contrast present in the bilateral femoral arteries.

The Role Of Autophagy During Myocardial Ischemia/Reperfusion Injury, Aloysius Ibe, Alisa Kim, Hannah Kim, Marquese Daniels, Lindon H. Young, Robert J. Barsotti, Qian Chen

Research Day

Autophagy is a housekeeping process to remove damaged cytoplasmic constituents. However, a debate persists on whether autophagy is beneficial or detrimental when an ischemic/reperfusion (I/R) insult occurs in the heart. This study tested the effects of autophagy enhancers (e.g. rapamycin and trehalose) and autophagy inhibitor (e.g. 3-methyladenine) on heart function and infarct size after global I (30 minutes) and R (45 minutes) when given prior to ischemia (pre-treatment) or at the beginning of reperfusion (post-treatment). We found that Rapamycin (25nM) pre-treatment and post-treatment significantly restored final left ventricular developed pressure (LVDP) to 75.4±9.1% and 60±5% of initial baseline respectively (both …
