From Oceans To Public Health: Impact Of Climate Change And Socioecological Factors On Non-Cholera Vibrio Spp., Karlen Enid Correa Vélez
Theses and Dissertations
Climate change-induced stressors, such as temperature, salinity, pH, and wildfire, are contributing factors to the increase in frequency of Vibrio infections, altering Vibrio geographical constraints. At the same time, the expansion of the coastal population is resulting in increased input of treated municipal wastewater into areas that are also experiencing Vibrio proliferation. Given that increases in ocean temperature and sea level coupled with increases in human activity in coastal waters support greater Vibrio-human interactions, it is important to examine factors and mechanisms within this socio-ecological coupled system that may further strengthen this interaction. This study aimed to better understand the …

Wastewater monitoring for virus infections within communities can complement conventional clinical surveillance. Currently, most SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) clinical testing is voluntary and inconsistently available, except for a few occupational and educational settings, and therefore likely underrepresents actual population prevalence. Randomized testing on a regular basis to estimate accurate population-level infection rates is prohibitively costly and is hampered by a range of limitations and barriers associated with participation in clinical research. In comparison, community-level fecal monitoring can be performed through wastewater surveillance to effectively surveil communities. However, epidemiologically defined protocols for wastewater sample site selection are lacking. …

As the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) pandemic engulfs millions worldwide, the quest for vaccines or drugs against the virus continues. The helicase protein of SARS-CoV-2 represents an attractive target for drug discovery since inhibition of helicase activity can suppress viral replication. Using in silico approaches, we have identified drugs that interact with SARS-CoV-2 helicase based on the presence of amino acid arrangements matching binding sites of drugs in previously annotated protein structures. The drugs exhibiting an RMSD of ≤ 3.0 Å were further analyzed using molecular docking, molecular dynamics (MD) simulation, and post-MD analyses. Using these approaches, we …

Stress, Alcohol Use, And Punitive Parenting During The Covid-19 Pandemic, Jennifer Price Wolf, Bridget Freisthler, Caileigh Chadwick
Faculty Research, Scholarly, and Creative Activity
Background
Emerging research suggests that parents are experiencing heightened stress during the COVID-19 pandemic. Parental stress is a risk factor for harsh or punitive parenting, and this association may be exacerbated by the use of alcohol.
Objective
We examine whether parental stress is associated with use of punitive parenting, as well as whether this association is modified by drinking pattern.
Participants & setting
We used advertisements and word-of-mouth to recruit 342 parents living in Central Ohio during the initial stay-at-home order for COVID-19.
Methods
We used geographic ecological momentary assessment (gEMA) to measure parental stress and punitive parenting during three …

Journal of Health Disparities Research and Practice
COVID-19 has exacted a severe toll on the United States population’s physical and mental health and its effects have been felt most severely among people of color and low socioeconomic status. Using illustrative case studies, this commentary argues that in addition to COVID-19 health disparities created by psychosocial stressors such as the inability to socially distance and access quality healthcare, environmental justice communities have the additional burden of disproportionate exposure to toxic contaminants that contribute to their higher risk of COVID-19. Environmental contaminants including heavy metals and persistent organic pollutants found contaminating their nearby environments can alter the immune response, …
