Genome-Based Pathogenicity Potential Of Salmonella Isolated From Diverse Sources, Jared Mr Crocco

Theses and Dissertations (Comprehensive)

Bacterial human pathogens are among the leading causes of death around the world, especially in low income and developing countries. One important element in a bacterium’s ability to cause disease are genes that directly contribute to pathogenicity called virulence factors. A second significant aspect are antimicrobial resistance genes which allow microorganisms to persist in the presence of antimicrobial agents. In this project I aimed to determine if Salmonella isolated from different sources differed in pathogenicity profiles based on the complement of genes identified through genomic analysis. Accordingly, Salmonella genomes were organized into 8 groups: animal, clinical, human, environmental, food, water …

Self-Supervised Pseudo Multi-Class Pre-Training For Unsupervised Anomaly Detection And Segmentation In Medical Images, Yu Tian, Fengbei Liu, Guansong Pang, Yuanhong Chen, Yuyuan Liu, Johan W. Verjans, Rajvinder Singh, Gustavo Carneiro

Research Collection School Of Computing and Information Systems

Unsupervised anomaly detection (UAD) methods are trained with normal (or healthy) images only, but during testing, they are able to classify normal and abnormal (or disease) images. UAD is an important medical image analysis (MIA) method to be applied in disease screening problems because the training sets available for those problems usually contain only normal images. However, the exclusive reliance on normal images may result in the learning of ineffective low-dimensional image representations that are not sensitive enough to detect and segment unseen abnormal lesions of varying size, appearance, and shape. Pre-training UAD methods with self-supervised learning, based on computer …

How Irish Medical Scientists Can Assist In The Improved Diagnosis Of Disease - Infectious Mononucleosis (Im) A Case In Point, Patrick Naughton

ORBioM (Open Research BioSciences Meeting)

The Epstein-Barr Virus (EBV) or human herpesvirus 4 (HHV-4) is the sole etiologic agent of the acute illness in humans described either as infectious mononucleosis (IM), or glandular fever. IM is a self-limiting disease with various but transient symptoms which include fever, fatigue, malaise, sore throat, swollen lymph glands (particularly of the neck), swollen liver and spleen. Diagnosis relies on clear, timely and informative laboratory test results. Patients with primary IM infection often present on investigation with a well-documented population of atypical/plasmacytoid lymphocytes. The qualitative detection of heterophile antibodies (HAs) is also a useful aid in the diagnosis of primary …

We conducted a study in 9 HCA hospitals in the southeastern United States to determine the number of patients who started on PPIs …

Coronary Artery Calcium Scoring In Asymptomatic Patients, Bilal Hussain, Ahmed Mahmood, Michael G. Flynn, Thomas Alexander

HCA Healthcare Journal of Medicine

Coronary artery calcium (CAC) scoring is an important prognostic tool for personalized cardiovascular preventive care and has recently been incorporated into American College of Cardiology/American Heart Association guidelines. CAC provides direct visualization and quantification of CAC burden for risk stratification and primary prevention of cardiovascular events in an asymptomatic population. CAC scoring is recommended for individuals with intermediate 10-year atherosclerotic cardiovascular disease (ASCVD) risk and selective populations with borderline ASCVD risk. In this review, we outline the interpretation of CAC scores for predicting the risk of cardiovascular events, and we highlight the guidelines for starting statin and potentially starting aspirin …

Atrial Fibrillation: Rate Versus Rhythm Control, Carlos E. Vargas, Mina Bhatnagar, Haris Ahmed, Michael G. Flynn, Thomas Alexander

HCA Healthcare Journal of Medicine

Atrial fibrillation (AF) remains the most common arrhythmia worldwide and is expected to affect approximately 12 million individuals in the United States alone by 2030. Thromboembolic events remain a feared complication of AF and should be treated and risk-stratified utilizing the CHA₂DS₂-VASc scoring system. Other complications of AF span a wide spectrum from impaired quality of life (QoL) to an increase in all-cause mortality. Rate control strategies consist of controlling the ventricular rate and have been shown to be a safe and effective strategy for asymptomatic AF patients. In patients who are plagued with symptoms leading to impaired QoL or …
