Cafo’S Are A Public Health Crisis:The Creation Of Covid-19, Helena Masiello

University of Miami Law Review

Concentrated Animal Feeding Operations (“CAFO’s”) are largely unregulated by State or Federal Laws in the United States. As a result of this lack of oversight, they are a breeding ground for deadly infectious diseases. The COVID-19 epidemic has demonstrated the threat that diseases pose to the United State like H1N1, SARS, and Ebola.
The USDA needs to regulate CAFOs under the mandate given to them by congress in the AHPA to ensure that they are not the epicenter of the next wave of deadly infectious diseases. Scientists have been warning about the disease potential of CAFOs for the last decade, …

Making Meaning Of Covid-19: An Exploratory Analysis Of U.S. Adolescent Experiences Of The Pandemic, Gabriel M. Velez, Madeline Hahn, Brian Troyer

College of Education Faculty Research and Publications

The COVID-19 pandemic will mark the lives and trajectories of adolescents who lived through it. The pandemic upended social contexts, disrupted schools, and, for many, impacted the physical, financial, and psychosocial health of themselves, their families, and their communities. Contextual changes, however, are not solely deterministic of developmental outcomes. As Bronfenbrenner’s Ecological Systems Theory and Spencer’s Phenomenological Variant of the Ecological Systems Theory demonstrate, young people interpret, make meaning, and respond to socioecological contexts as part of their developmental processes. The current study explored meaning making qualitatively through how adolescents in the United States were experiencing COVID-19. Participants were asked …

Smith, Erin Oakley, Siran He, Rebecca Zavala, Kacey Ferguson, Gargi Wable Grandner, Ibukun-Oluwa Omolade Abejirinde, Yalda Afshar, Homa Ahmadzia, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

We urgently need answers to basic epidemiological questions regarding SARS-CoV-2 infection in pregnant and postpartum women and its effect on their newborns. While many national registries, health facilities, and research groups are collecting relevant data, we need a collaborative and methodologically rigorous approach to better combine these data and address knowledge gaps, especially those related to rare outcomes. We propose that using a sequential, prospective meta-analysis (PMA) is the best approach to generate data for policy- and practice-oriented guidelines. As the pandemic evolves, additional studies identified retrospectively by the steering committee or through living systematic reviews will be invited to …

Part I Antimicrobial Resistance: Bacterial Pathogens Of Dermatologic Significance And Implications Of Rising Resistance, Saira George, Fiorinda F Muhaj, Celine D Nguyen, Stephen K Tyring

Faculty, Staff and Student Publications

Although the COVID-19 pandemic has been the defining global health crisis of our time, public health officials have been sounding the alarm of another ominous threat for years: an impending antimicrobial resistance crisis. In dermatology, antibiotics are often used for prolonged courses in the treatment of skin and soft tissue infections and common inflammatory skin conditions, increasing the risk of microbiome alteration and antibiotic-related adverse effects, all while exerting consequential selective pressures on both pathogenic and bystander bacteria. In this review, we hope to raise awareness of the crisis of antimicrobial resistance and review resistance concerns related to dermatology-relevant bacterial …

Hemoglobin As A Predictor For Covid-19 Disease Severity, Nicholas Sarcia, Dan Thai, Andrea M. Bodine Md

Advances in Clinical Medical Research and Healthcare Delivery

Background: The dilemma of who is at highest risk for COVID-19 severe disease and death persists. Hemoglobin levels may be an indicator of COVID-19 disease severity. There is inconsistent data on Emergency Department (ED) hemoglobin levels and severity of disease. Our objective was to examine if COVID-19 patients presenting with abnormal hemoglobin levels have an increased risk of severe disease and in-hospital mortality.

Methods: We conducted a retrospective cohort study at Berkshire Medical Center in Pittsfield, MA to investigate the relationship of COVID-19 disease severity with hemoglobin level. Inclusion criteria consisted of ED patients over 18 years with …

Disease Severity In Covid-19 Breakthrough Cases, Dan Thai, Nicholas Sarcia, Andrea M. Bodine Md

Advances in Clinical Medical Research and Healthcare Delivery

Background

Vaccine breakthrough is a phenomenon wherein vaccinated individuals become infected with disease despite adequate protection. During this study period, the Centers for Disease Control (CDC) reported 66.6% of US people have been fully vaccinated. Any measures to improve trust would increase vaccination rates. This study aims to understand vaccine breakthrough cases in COVID-19 by comparing their severity to unvaccinated cases. Our objective is to compare disease severity based on the worst initial vital signs (temperature, respiratory rate, oxygen saturation), length of stay (LOS), and age between vaccinated and unvaccinated COVID-19 cases.

Methods

We conducted a retrospective cohort study at …

Neutralization capacity of antibodies against Omicron after a prior SARS-CoV-2 infection in children and adolescents is not well studied. Therefore, we evaluated virus-neutralizing capacity against SARS-CoV-2 Alpha, Beta, Gamma, Delta and Omicron variants by age-stratified analyses (5 years of age. As expected, convalescent pediatric COVID-19 and MIS-C cohorts demonstrate higher neutralization titers than hospitalized acute COVID-19 patients. Overall, children and adolescents show some loss of cross-neutralization against all variants, with the most pronounced loss against Omicron. In contrast to SARS-CoV-2 infection, children vaccinated twice demonstrated higher titers against Alpha, Beta, Gamma, Delta and Omicron. These findings can influence transmission, re-infection …

Multivalent Designed Proteins Neutralize Sars-Cov-2 Variants Of Concern And Confer Protection Against Infection In Mice, Andrew C Hunt, James Brett Case, Rita E Chen, Baoling Ying, Adam L Bailey, Natasha M Kafai, Michael S Diamond, Et Al

Open Access Publications

New variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continue to arise and prolong the coronavirus disease 2019 (COVID-19) pandemic. Here, we used a cell-free expression workflow to rapidly screen and optimize constructs containing multiple computationally designed miniprotein inhibitors of SARS-CoV-2. We found the broadest efficacy was achieved with a homotrimeric version of the 75-residue angiotensin-converting enzyme 2 (ACE2) mimic AHB2 (TRI2-2) designed to geometrically match the trimeric spike architecture. Consistent with the design model, in the cryo-electron microscopy structure TRI2-2 forms a tripod at the apex of the spike protein that engaged all three receptor binding domains simultaneously. …
