Section of Cardiology

Background: Smartphone-based applications to identify cardiac implantable electronic devices (CIED) are extremely useful in circumstances, where urgent device interrogation is needed, and a device identification card is not available. Few studies have provided insights regarding the utility of these applications. We have studied two widely available applications i.e., Pacemaker ID app (PMIDa) or Cardiac Rhythm Management Device-Finder (CRMD-f) to identify device manufacturers in CIEDs.
Methods: 547 patients who underwent CIED implantation from the year 2016-2020 in our institute were enrolled. There were 438 Medtronic and 109 St. Jude's devices. All chest radiographs were de-identified and resized into 225*225 pixels focusing …

This study describes the development of an objective early warning score using HVT, for identification of infants with single ventricle at risk for clinical deterioration and unplanned hospital admissions (UHA).

Methods and Results: Six candidate scoring parameters were selected to develop a pragmatic score for routine evaluation of HVT during the interstage period. We evaluated the individual and combined ability of these parameters to predict UHA. All infants with single ventricle monitored at home …

The Reel Deal: The Stacked Benefits Of A Reel Mower, John K. Hix, Simone Bailey

Advances in Clinical Medical Research and Healthcare Delivery

"Mow-lawning" is a colloquial term referred to actively cutting grass using a reel mower, typically at a faster than normal pace in order to maximize exercise benefit and minimize time, with the emphasis on the physical action of mowing and only secondarily on the resulting lawn care. While mow-lawning remains relatively uncommon in the United States, adoption of this practice by those healthy enough to engage in the level of exercise required can deliver a number of benefits that improve environmental, safety, and personal goals simultaneously. The stacking of so many benefits in one practice deserves more attention and promotion.

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Vascular calcification is an active process that increases cardiovascular disease (CVD) risk. There is still no consensus on an appropriate biomarker for vascular calcification. We reasoned that the biomarker for vascular calcification is the collection of all blood components that can be sensed and integrated into a calcification response by human vascular smooth muscle cells (hVSMCs).

METHODS: We developed a new cell-based high-content assay, the BioHybrid assay, to measure in vitro calcification. The BioHybrid assay was compared with the o-Cresolphthalein assay and the T50 assay. Serum and plasma were derived from different cohort studies including chronic kidney disease (CKD) …

In Patients With Cardiac Arrest, Does Early Defibrillation Reduce Mortality?, Nicholas Lueddecke

Theses and Graduate Projects

Background: Cardiac arrest is a devastating disorder that affects millions of people each year. Often having a sudden onset, cardiac arrest is almost certainly lethal if prompt treatment is not started. In hopes to both better understand how treatment of cardiac arrest has evolved and to quantitatively measure the outcome of defibrillation, multiple pieces of literature have been reviewed.

Methods: Articles were found that were pertinent by using PubMed and Google Scholar. Literature was obtained that researched a wide spectrum of topics relating to defibrillation and cardiac arrest that did not focus on traumatic cardiac arrests as it is beyond …

Ventricular Fibrillation Due To A Likely Pathogenic Sos1 Variant: An Unrecognized Etiology Of Infantile Sudden Death?, Christopher Follansbee, Lindsey Malloy-Walton

Manuscripts, Articles, Book Chapters and Other Papers

We present the case of a female infant presenting after a ventricular fibrillation arrest found to have ectopic atrial tachycardia (EAT). Evaluation revealed a likely pathogenic variant in SOS1 not previously reported in affected individuals. SOS1 variants are associated with Noonan syndrome, which belongs to a family of related genetic syndromes affecting the RAS/MAPK signaling pathway. To date, this is the first case reported of a ventricular fibrillation arrest in a patient with a RASopathy-related variant prior to development of the typically associated structural cardiac phenotype and may represent a previously unrecognized etiology of sudden death during infancy.

Journal of the Saudi Heart Association

Introduction and Objectives: Frailty has been studied extensively in elderly population as a predictor and prognostic marker for morbidity and mortality. Frailty is being increasingly recognised as a distinct pathophysiological condition which plays a major role in outcomes of various disease states including heart failure. Our aim was to study the prevalence of frailty in heart failure and see its prognostic significance in such patients. Methods: This was a prospective study conducted in an out-patient HF clinic. All consecutive patients with HF, > 25 years age, with LVEF < 40 % were included. All patients were asked a simple frailty questionnaire. Hand-dynamometer was used to assess handgrip strength in kilograms and were classified as frail, pre-frail or non-frail. The primary end point was cardiovascular mortality and hospitalization, and secondary end-point was composite of all cause mortality, hospitalization,device implantation and documented arrythmia. Results: 210 patients were studied for clinical outcomes.Mean age was 60.59+ 11.55 years with 15 % patients aged less than 50 years. Mean LVEF was 30.24+ 6.8%. Handgrip strength was poor in the frail vs non/pre-frail patients (p=0.001) with a strength >16.95 kg having sensitivity of 72% and specificity of 63% for the prediction …

Methods: One thousand six patients with AHF from 9 Sub-Saharan African countries were recruited in THESUS-HF, of which 143 (14.3%) had RHD-AHF. Clinical characteristics and outcomes in patients with RHD-AHF and non-RHD-AHF were compared. Kaplan-Meier plots for time to all-cause death and/or HF readmission according to the presence of RHD-AHF and non-RHD-AHF were performed and survival distributions compared using the log-rank test. Cox regression was used to determine the hazard ratio of …

Smart Watch Detection Of Supraventricular Tachycardia (Svt): First Case From Tanzania, Nadeem Kassam, Omar Aziz, Eric Aghan, Samina Somji, Hanifa Mbithe, Mustaafa Bapumia, Robert Mvungi, Salim Surani

Internal Medicine, East Africa

Smartwatches like the Apple Watch have been on the rise worldwide and their use is gaining popularity in developing countries. Their ability to detect dysrhythmias is well documented. Present practice discourages the use of these devices as a diagnostic tool. Nevertheless, atypical findings from these devices should be clinically investigated. This case demonstrates an eventual diagnosis of supraventricular tachycardia (SVT) based on an Apple watch alert which was subsequently confirmed by electrophysiological evaluation.

The Impacts Of Aging, Sedentarism, And Exercise On Neurotrophic Factor Expression And Innervation In The Heart And The Effects Of Treatment With Α-Cgrp On Heart Function, Gabriel Almeida Alves

Dissertations

Neurotrophic factors (NFs) are important molecules responsible for development, differentiation, regeneration, and maintenance of new and mature neurons. Neurotrophic factors act as neurocytokines and may assist with the regulation of axonal and dendritic arrangements and synaptic plasticity between neurons themselves or with other non-neural target tissues. In this study, we analyze the levels of two NFs: glial cell line-derived neurotrophic factor (GDNF) and nerve growth factor (NGF). Cardiomyocytes produce these neurotrophic factors which assist with the innervation pattern of the heart. The heart is innervated by the two branches of the autonomic nervous system; namely the sympathetic nervous system and …

Artificial intelligence (AI) algorithms integrate the diagnosis of AF electrocardiogram (ECG) and predict the possibility that AF will occur in the future. In this paper; we utilized the MIT-BIH AF Database (AFDB); which is composed of data from normal people and patients with AF and onset characteristics; and the AFPDB database (i.e.; PAF Prediction Challenge Database); which consists of data from patients with Paroxysmal AF (PAF; the records contain the ECG preceding an …

Anaesthetic Management Of Tracheal Injury Following Blunt Neck Trauma: An Unusual Late Presentation, Muhammad Saad Yousuf, Mohammad Bin Pervez, Saulat Fatimi, Khalid Samad

Department of Anaesthesia

Tracheal injuries, following blunt neck trauma, are life-threatening surgical emergencies with high risk of mortality. A high index of suspicion is necessary to avoid missing an occult injury because delays in diagnosis and definitive treatment are associated with poorer outcomes. We, herein, report a case of a 28-year man who presented in Emergency Department 15 days after blunt neck trauma from an accident involving electric cable. Anaesthetic challenges, airway management and importance of effective close loop communication, during repair of complex tracheal reconstruction, will be discussed in this case report.
