Assessment Of Veteran Satisfaction With Telehealth Services During The Covid-19 Pandemic, Rhonda Kay Howard Dec 2022

Assessment Of Veteran Satisfaction With Telehealth Services During The Covid-19 Pandemic, Rhonda Kay Howard

Electronic Theses and Dissertations

Abstract

With the advent of the COVID-19 public health emergency in the United States, many U.S. veterans were unable to maintain their usual office visits due to safe access concerns. Patients were strongly encouraged to maintain their healthcare needs at home by utilizing online technology resources like telehealth services with their healthcare providers. Providing excellent healthcare services for veterans during COVID-19 became a challenge for primary care providers at many veteran healthcare organizations. Since little was known about the satisfaction of veteran clients with healthcare management using virtual care during the pandemic, this formative program evaluation was designed to survey …

All Peer-Reviewed Publications

Objective: The outbreak of the novel coronavirus disease 2019 (COVID-19) is still affecting African countries. The pandemic presents challenges on how to measure governmental, and community responses to the crisis. Beyond health risks, the socio-economic implications of the pandemic motivated us to examine the transmission dynamics of COVID-19 and the impact of non-pharmaceutical interventions (NPIs). The main objective of this study was to assess the impact of BCG vaccination and NPIs enforced on COVID-19 case-death-recovery counts weighted by age-structured population in Ethiopia, Kenya, and Rwanda. We applied a semi-mechanistic Bayesian hierarchical model (BHM) combined with Markov Chain Monte Carlo (MCMC) …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The COVID-19 pandemic has impacted many lives around the world, leaving negative repercussions including health effects, economic downturns, and social and physical restrictions. The pandemic has also revealed many disproportionate health impacts on vulnerable populations, especially among the Hispanic and Latinx populations. The use of the three COVID-19 vaccines in the United States has presented a form of protection against additional negative impacts. However, hesitancy toward the COVID-19 vaccine has hindered its rapid uptake, preventing the country from reaching herd immunity and ultimately ending the pandemic. Current research is minimal in understanding the intentions of receiving the COVID-19 vaccine among …

Ubiquitin Variants Potently Inhibit Sars-Cov-2 Plpro And Viral Replication Via A Novel Site Distal To The Protease Active Site, Vera J. E. Van Vliet, Nitin Sharma, Safder S. Ganaie, Gaya K. Amarasinghe, Et Al

2020-Current year OA Pubs

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has made it clear that combating coronavirus outbreaks benefits from a combination of vaccines and therapeutics. A promising drug target common to all coronaviruses-including SARS-CoV, MERS-CoV, and SARS-CoV-2-is the papain-like protease (PLpro). PLpro cleaves part of the viral replicase polyproteins into non-structural protein subunits, which are essential to the viral replication cycle. Additionally, PLpro can cleave both ubiquitin and the ubiquitin-like protein ISG15 from host cell substrates as a mechanism to evade innate immune responses during infection. These roles make PLpro an attractive antiviral drug target. Here we demonstrate that ubiquitin …

BACKGROUND: Coronavirus Disease 2019 (COVID-19) can lead to the development of acute respiratory distress syndrome (ARDS). In some patients with non-resolvable (NR) COVID-19, lung injury can progress rapidly to the point that lung transplantation is the only viable option for survival. This fatal progression of lung injury involves a rapid fibroproliferative response and takes on average 15 weeks from initial symptom presentation. Little is known about the mechanisms that lead to this fulminant lung fibrosis (FLF) in NR-COVID-19.

METHODS: Using a pre-designed unbiased PCR array for fibrotic markers, we analyzed the fibrotic signature in a subset of NR-COVID-19 lungs. We …

Faculty, Staff and Students Publications

BACKGROUND: SARS-CoV-2 infection in the age group of 0-17 years contributes to approximately 22% of all laboratory-confirmed SARS-CoV-2 infections. Fortunately, this age group has a lower death rate (0.5 per 100 000) that accounts for only 4% of the total deaths due to COVID-19. Despite the low mortality rate in the pediatric population, children of minority groups represented 78% of the deaths highlighting the existing disparities in access to health care.

METHODS: With the emergence of the more contagious COVID-19 variants and the relatively slow pace of vaccination among the pediatric population, it is possible to see more cases of …

Immunomodulation and immunity from vaccination and natural infection have reduced mortality from coronavirus disease 2019 (COVID-19). However, there are ongoing concerns regarding emerging variants and residual pulmonary sequelae in survivors, given that the lungs are the principal site for the triumvirate of infection, inflammation and injury. The initial waves of acute, severe COVID-19 were profoundly inflammatory, usually manifest as organising pneumonia ± acute respiratory distress syndrome (ARDS). The extent of the fibrogenic potential of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and the modifiability of the pathogenic processes and disease course are unclear. Interestingly patients can develop ‘post-COVID interstitial lung disease’ …

Incidence Of An Insulin-Requiring Hyperglycemic Syndrome In Sars-Cov-2-Infected Young Individuals: Is It Type 1 Diabetes?, Massimo Pietropaolo, Peter Hotez, Nick Giannoukakis

Center for Medical Ethics and Health Policy Staff Publications

Pancreatic ACE2 receptor expression, together with increased prevalence of insulin-requiring hyperglycemia in patients with coronavirus disease 2019 (COVID-19), suggested that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pancreatic infection might trigger a β-cell-selective inflammation precipitating autoimmune type 1 diabetes (T1D). We examined T1D incidence in patients with COVID-19 inside a large, global population using a "big data" approach. The incidence in 0-30-year-old patients with confirmed COVID-19 over an ∼15-month period from the beginning of the COVID-19 pandemic was compared with an age-matched population without COVID-19 inside the TriNetX COVID-19 Research Network (>80 million deidentified patient electronic medical records globally). …

This article reports on an Australian study, completed before the COVID-19 pandemic, of the university experiences of undergraduate women nurse students with family responsibilities. The findings reveal the importance of factors outside the university on the women students’ practicum experience and their ability to engage and achieve. Methods: The study was qualitative, …

Research outputs 2022 to 2026

COVID-19 had a significant impact on construction projects due to labor shortages and COVID-19 restrictions, yet little is known about the impact it had on construction safety.

The study collected data from safety climate surveys, leading and lagging safety indicators and used linear regression to compare safety performance pre and post the onset of COVID-19. Our results showed after the onset of COVID-19 there was a significant reduction (Pr > F at 0.05 %) in incident rate, …

INTRODUCTION: Fewer cancer diagnoses have been made during the COVID-19 pandemic. Pandemic-related delays in cancer diagnosis could occur from limited access to care or patient evaluation delays (e.g., delayed testing after abnormal results). Follow-up of abnormal test results warranting evaluation for cancer was examined before and during the pandemic.

METHODS: Electronic trigger algorithms were applied to the Department of Veterans Affairs electronic health record data to assess follow-up of abnormal test results before (March 10, 2019-March 7, 2020) and during (March 8, 2020-March 6, 2021) the pandemic.

RESULTS: Electronic triggers were applied to 8,021,406 veterans' electronic health records to identify …

Background:

The impacts of the COVID-19 pandemic have been vast and are not limited to physical health. Many adolescents have experienced disruptions to daily life, including changes in their school routine and family’s financial or emotional security, potentially impacting their emotional wellbeing. In low COVID-19 prevalence settings, the impact of isolation has been mitigated for most young people through continued face-to-face schooling, yet there may still be significant impacts on their wellbeing that could be attributed to the pandemic.

Methods:

We report on data from 32,849 surveys from Year 7–12 students in 40 schools over two 2020 survey cycles (June/July: …
