HCA Healthcare Journal of Medicine

A 24-year-old African American male with a history of sickle cell anemia (Hb S/S) presented to an outside hospital with acute colitis, acute renal failure and sickle cell crisis and was treated with supportive measures. On day 3 of hospitalization, he developed bilateral ascending paralysis with sacral numbness. Magnetic resonance imaging (MRI) demonstrated epidural lipomatosis, which was attributed as the cause of his paralysis. He was transferred to our facility for neurosurgery evaluation. Based on the physical examination, Guillain-Barré Syndrome (GBS) was suspected. This conclusion lead to a lumbar puncture with cerebrospinal fluid (CSF) analysis that confirmed the diagnosis. He …

Hemodynamic Management Of Patients With Ejection Fraction < 50% Undergoing Pulmonary Vein Ablation, Aaron B. Hesselson, Heather Hesselson

Internal Medicine Faculty Publications

There is no consensus regarding optimal methodology forblood pressure monitoring inpatients with a depressed ejection fraction undergoingcatheter ablationfor atrial fibrillation. Our goalswere to determine ifhemodynamicmanagementdifferences exist during radiofrequency ablation for atrial fibrillation in patients with and without an ejection fraction< 50%, and whether management was influenced by the utilization of invasive arterial blood pressure monitoring. This single-center trial retrospectively compared blood pressure management during catheterablation of atrial fibrillationin all patients with an ejection fraction< 50% over a 2-year span (n=44), and compared to an age-matched cohort with preserved ejection fraction ablated over the same span in time (n=44). Blood pressure was not significantly managed differently between the groups, and did not appear to be influenced by the use of invasive arterial blood pressure monitoring. Hemodynamic management is similar across the spectrum of ejection fraction, regardless of invasive arterial blood pressure monitoring, which challenges the need for invasive arterial blood pressure monitoringduringcatheter ablation ofatrial fibrillationin left ventricular systolic dysfunction.

Bone Quality In Chronic Kidney Disease Patients: Current Concepts And Future Directions – Part Ii, Kamyar Asadipooya, Mohamed Abdalbary, Yahya Ahmad, Elijah Kakani, Marie-Claude Monier-Faugere, Amr El-Husseini

Internal Medicine Faculty Publications

Background: Patients with chronic kidney disease (CKD) have an increased risk of osteoporotic fractures, which is due not only to low bone volume and mass but also poor microarchitecture and tissue quality. The pharmacological and nonpharmacological interventions detailed, herein, are potential approaches to improve bone health in CKD patients. Various medications build up bone mass but also affect bone tissue quality. Antiresorptive therapies strikingly reduce bone turnover; however, they can impair bone mineralization and negatively affect the ability to repair bone microdamage and cause an increase in bone brittleness. On the other hand, some osteoporosis therapies may cause a redistribution …

Bone Quality In Ckd Patients: Current Concepts And Future Directions – Part I, Kamyar Asadipooya, Mohamed Abdalbary, Yahya Ahmad, Elijah Kakani, Marie-Claude Monier-Faugere, Amr El-Husseini

Internal Medicine Faculty Publications

Background: There is ample evidence that patients with CKD have an increased risk of osteoporotic fractures. Bone fragility is not only influenced by low bone volume and mass but also by poor microarchitecture and tissue quality. More emphasis has been given to the quantitative rather than qualitative assessment of bone health, both in general population and CKD patients. Although bone mineral density (BMD) is a very useful clinical tool in assessing bone strength, it may underestimate the fracture risk in CKD patients. Serum and urinary bone biomarkers have been found to be reflective of bone activities and predictive of fractures …

Intraluminal Endovascular Coil Migration: A Rare Complication Post-Embolization Of The Gastroduodenal Artery For A Previously Bleeding Duodenal Ulcer, Yassin Naga, Mahendran Jayaraj, Yousif Elmofti, Annie Hong, Gordon Ohning

School of Medicine Faculty Research

Transarterial angiographic embolization is a highly effective, safe treatment for non-variceal upper gastrointestinal bleeding refractory to endoscopic intervention. However, intraluminal coil migration is a possible complication. Coil migration, while usually a self-limiting process, can lead to significant rebleeding. In our case, a patient presented with a life-threatening duodenal ulcer hemorrhage, likely precipitated by intraluminal endovascular coil migration after a recent gastro-duodenal artery embolization. He was successfully managed without endoscopic coil removal and had no additional gastrointestinal bleeding. It is important for endoscopists to be aware of this complication and weigh the risks and benefits of coil removal.

An Ensemble Of The Icluster Method To Analyze Longitudinal Lncrna Expression Data For Psoriasis Patients, Suyan Tian, Chi Wang

Internal Medicine Faculty Publications

BACKGROUND: Psoriasis is an immune-mediated, inflammatory disorder of the skin with chronic inflammation and hyper-proliferation of the epidermis. Since psoriasis has genetic components and the diseased tissue of psoriasis is very easily accessible, it is natural to use high-throughput technologies to characterize psoriasis and thus seek targeted therapies. Transcriptional profiles change correspondingly after an intervention. Unlike cross-sectional gene expression data, longitudinal gene expression data can capture the dynamic changes and thus facilitate causal inference.

METHODS: Using the iCluster method as a building block, an ensemble method was proposed and applied to a longitudinal gene expression dataset for psoriasis, with the …

Heart failure (HF) is the leading cause of 30-day hospital readmission, with up to 23.5% of Medicare beneficiaries requiring subsequent admission within 30 days post hospital discharge (CMS, 2020a). Mobile-health applications (MHA), such as smartphone applications, have emerged as cost-effective methods to safely manage chronic disease in the outpatient setting (Inglis et al., 2015). The purpose of this evidence-based practice (EBP) project was to evaluate the impact of a MHA on HF-related 30-day readmission rates. The Iowa Model Revised guided the implementation of the project in a rural, for-profit hospital in Northwest Indiana. An extensive literature search was conducted, and …

Hypertension Management: Improving Medication Adherence Through The Use Of Daily Text Messages, Gaelle Bulabula

Evidence-Based Practice Project Reports

Hypertension (HTN) is the leading cause of hospitalization and is responsible for approximately 50% of cardiovascular and cerebrovascular events (Al-Noumani, et al., 2018). Uncontrolled HTN can lead to comorbidities including ischemic heart disease, renal disease, or life-threatening arrythmias (World Health Organization [WHO], 2019). The leading cause of HTN is medication non-compliance (Varleta, et al., 2017). The purpose of this evidence-based practice project was to determine the effectiveness of daily text messages on antihypertensive medication adherence. A comprehensive review of literature generated ten high-level evidence studies demonstrating that daily text messages near each medication dosing time is best practice for improving …

Biochemical And Echocardiographic Markers For The Early Detection Of Cardiotoxicity Under Monoclonal Antibodies Therapy, Ionela-Emilia Popovici, Angela Cozma, Olga Hilda Orasan, George Ciulei, Ana Maria Poenar, Cristina Buchman, Simina Tarmure, Sorina Secara, Adela Sitar-Taut, Teodora Alexescu, Andrada Lazar, Vasile Negrean, Lucia Maria Procopciuc

Journal of Mind and Medical Sciences

The progress made over the past years in the field of cancer therapy has led to a significant decrease in cancer mortality, but these therapies have many adverse effects, cardiovascular effects being among the most frequent ones. For increasing lifelong expectancy of surviving cancer patients, cardiac monitoring represents an important task. Current studies and practice recommend echocardiography using strain analysis for monitoring the cardio toxic effects of cancer therapy. The potential of combining imaging techniques with biomarkers for the early detection and diagnosis seems a promising path for future research.

Pvn Activity In Cardiac Sympathetic Afferent Reflex (Csar) Control And Cardiovascular Function, Shane H. Boomer

Honors Thesis

Regulation of blood pressure is essential in bodily health. Hypertension and hypotension can be associated with varying diseases that could potentiate further disease. From this, understanding the mechanisms that regulate blood pressure is important within medicine. In my study, I will be focusing on a cardiovascular reflex that is less well understood, the cardiac sympathetic afferent reflex (CSAR). In particular, this work will examine sex differences in this reflex in overall function and in the involvement of an area of the brain called the paraventricular nucleus (PVN). We will test the hypothesis that there will be a significant difference between …

Intimate Partner Violence Is A Barrier To Antiretroviral Therapy Adherence Among Hiv - Positive Women: Evidence From Government Facilities In Kenya, Bornice C. Biomndo, Alexander Bergmann, Nils Lahmann, Lukoye Atwoli

Internal Medicine, East Africa

Introduction: Intimate Partner Violence (IPV) is linked to low engagement with HIV management services and adverse clinical outcomes, including poor ART adherence. In sub-Saharan Africa, studies on pregnant/postpartum women and transactional sex workers have produced divergent evidence regarding IPV’s association with poor ART adherence. We investigate this association among a broad group of women.

Methods: We sampled 408 HIV-positive women receiving free ART from different types of HIV clinics at government health facilities, assessing for IPV exposure by a current partner, ART adherence rate, and other factors that affect ART adherence (e.g. education, disclosure). ART adherence rates were measured using …

Hepatic ischemia and reperfusion (IR) injury contributes to the morbidity and mortality associated with liver transplantation. microRNAs (miRNAs) constitute a family of noncoding RNAs that regulate gene expression at the posttranslational level through the repression of specific target genes. Here, we hypothesized that miRNAs could be targeted to enhance hepatic ischemia tolerance. A miRNA screen in a murine model of hepatic IR injury pointed us toward the liver-specific miRNA miR122. Subsequent studies in mice with hepatocyte-specific deletion of miR122 (miR122loxP/loxP Alb-Cre+ mice) during hepatic ischemia and reperfusion revealed exacerbated liver injury. Transcriptional studies implicated hypoxia-inducible factor-1α (HIF1α) in the induction …
