Tool Development for Analyzing Arrhythmias in Fast Cardiac Magnetic Resonance Scans
Cardiac magnetic resonance (CMR) scanning provides a method to diagnose cardiac disease. For obtaining an effective image, the standard procedure of CMR requires patients to hold their breath during the scanning, but it is difficult for frail patients in clinic. Furthermore, standard CMR imaging depends upon averaging together regular cardiac cycles, which is disrupted by irregular heartbeats, this irregularity prevents visualization of arrhythmias. HeartSpeed software will introduce a new strategy to help frail patients, magnetic resonance technicians, and physicians, by enabling free-breathing CMR image post-processing that corrects the breathing motion. Closely related algorithms provide a new approach to visualize and…

Early Detection of Glaucoma Using Electronic Health Records
Glaucoma is the second leading cause of irreversible blindness worldwide. About 70 million people have glaucoma, and nearly 4.4 million people are blind from optic nerve damage due to undiagnosed glaucoma. Besides, the current glaucoma growth rate and its economic burdens are unsustainable. As a result, warrant a systematic evaluation for glaucoma risk assessment and early prediction for better glaucoma care management. Effective use of temporal information across electronic health records (EHR) provides data-driven and evidence-based risk factors linked to glaucoma development and supports the early predictive model. In the present study, we used 830,125 unique patient records from the…

Evaluation of chronic disease self-management information on social media using evidenced-based frameworks
The management of chronic diseases requires considerable patient education and self-management. Diabetes, cancer and mental illness are among the top ten searched chronic diseases on social media, a platform where people increasingly seek and disseminate information. Social media platforms such as Twitter can potentially shape online conversations and perceptions about chronic disease management. In this study, we analyze diabetes self-management (DSM) information on Twitter using AADE7™ behavioral guidelines. This study aims to illustrate that social network analysis based on such evidence-based behavioral frameworks can be used to inform the analysis of chronic disease information shared on social media. This approach…

Analysis of snRNA-seq from CDX Models of Non-Small Cell Lung Cancer Identified Subpopulation of Cells Potentially Responsible for Tumor Progression
Circulating tumor cells (CTCs) are considered as seeds of metastasis and have potential to be used as biomarkers in cancer. Understanding the biology of CTCs is critical to evaluate tumor progression and response to treatment. Additionally, studying transcriptome of CTCs–derived tumors aids in deciphering the causes underlying metastasis. Single nuclei-RNA-sequencing (snRNA-seq) is an emerging technology that allows investigators to study individual cells with molecular typing to that drives tumor growth and resistance to therapy. In this study, we use novel human CTC-derived xenograft (CDX) mouse models of non-small cell lung cancer (NSCLC) and snRNA-seq to determine genetic and cellular drivers of…

What to Learn and What to Avoid from ClinicalTrials.gov for New Trial Design When Repurposing Drugs for Precision Medicine?
Clinical trials are essential in the process of new drug development and repositioning. As clinical trials involve significant investments of time and money, it is crucial for trial designers to carefully investigate trial settings prior to launching it. In the 356,282 trials registered on ClinicalTrials.gov , one can search similar trial setting with the current trial of interest and identify prior or ongoing trials that share similar patient’s population, genetic characteristics, intervention means, etc. It is a wise strategy to learn from successful trials and to avoid repeating mistakes from failed trials. For example, in our computational drug repositioning project…

A Case-Control based Genomic Analysis of Chronic Obstructive Pulmonary Disease
Chronic Obstructive Pulmonary Disease (COPD) is a respiratory illness that affects millions of people all over the world. It is a major cause of chronic morbidity and mortality and a serious global public health problem. COPD is the fourth leading cause of death worldwide. Although the environmental causes of COPD which predominantly include cigarette smoking are well-documented, to this date the genetic underpinnings of COPD remain largely unknown. Furthermore, in the current landscape of a respiratory pandemic, COPD patients are at a much higher risk for developing other respiratory illnesses and co-morbidities. In this study we use genomic data from…

Risk Factors for Thyroid Cancer, a Systematic Review
Thyroid cancer accounted for 1 out of every 20 female cancer diagnoses worldwide in 2018; the etiology of this disease is not well understood, and preventive programs are not established. It is well known that thyroid cancer incidence has been increasing since the 1980s, largely attributed to the increase in diagnosis of papillary thyroid cancer and improvements in detection and diagnosis. Currently, exposure to ionizing radiation is the only well-established risk factor for thyroid cancer. Literature published in the English language between 1946 and September 2020 was searched via MEDLINE. A building-block strategy was used to identify articles of interest: “thyroid neoplasms”…

FatPlants: A Comprehensive Website Platform of Plant Fat Related Genes, Proteins and Metabolism
Increasing seed oil content by plant breeding has resulted in trade-offs or penalties with respect to protein content, seed size, or seed set. The molecular basis for this impasse is mostly speculative. Use of current global profiling approaches to better understand both the metabolic consequences of higher oil and the basis for reduced yield must also deal with off-target genetic mutations (even in near-isogenic lines), ultimately confounding cause-effect interpretations. We propose a diverse, integrated strategy to study the consequences of higher lipid production by studying transgenic plants specifically engineered to produce higher seed oil. As a part of this collaborative project,…

Development of A Blockchain Framework for Virtual Clinical Trials
Clinical trials are essential for discovering new treatments, but there are multiple challenges to patient recruitment, patient engagement, and cost containment. Virtual clinical trials (VCT) are an innovative approach that provides potential solutions by conducting home-based, rather than site-based, clinical trials. Virtual clinical trials are still the exception rather than general practice due to technical barriers. “Blockchain,” a distributed ledger technology, is a perfect match for virtual clinical trials. Its peer-to-peer design, security settings, and data transparency meet the needs of many healthcare applications. The programmable “Smart Contract” feature makes blockchain more suitable and feasible for VCT by solving computational…
