Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a historic pandemic of respiratory disease (coronavirus disease 2019 [COVID-19]), and current evidence suggests that severe disease is associated with dysregulated immunity within the respiratory tract. However, the innate immune mechanisms that mediate protection during COVID-19 are not well defined. Here, we characterize a mouse model of SARS-CoV-2 infection and find that early CCR2 signaling restricts the viral burden in the lung. We find that a recently developed mouse-adapted SARS-CoV-2 (MA-SARS-CoV-2) strain as well as the emerging B.1.351 variant trigger an inflammatory response in the lung characterized by the expression of …

The Effect Of Hydroxychloroquine On Mortality In Hospitalized Covid-19 Patients, Misha Suresh, Jeff Abraham

Physician Assistant Capstones, 2020-current

As of October 2020, there are no commonly accepted or proven effective treatments for coronavirus disease 2019 (COVID-19). Hydroxychloroquine (HCQ) is an established anti-malarial drug with demonstrated action against SARS-CoV-2 (the virus that causes COVID-19) in-vitro and early observational studies and anecdotal evidence supported its use in treatment of COVID-19. In this review, three of largest and most statistically powerful studies to date (two cohort studies and one randomized controlled trial [RCT]) are synthesized for the purpose of determining whether HCQ is effective in reducing mortality in patients hospitalized with COVID-19.

Creating Cautionary Tales: Institutional, Judicial, And Societal Indifference To The Lives Of Incarcerated Individuals, Nicole B. Godfrey

Arkansas Law Review

It has long been said that a society’s worth can be judged by taking stock of its prisons. That is all the truer in this pandemic, where inmates everywhere have been rendered vulnerable and often powerless to protect themselves from harm. May we hope that our country’s facilities serve as models rather than cautionary tales. Justice Sonia Sotomayor, joined by Justice Ruth Bader Ginsburg, issued the above-quoted clarion call to protect the lives of incarcerated people on May 14, 2020. At that point, the COVID-19 pandemic had brought American society to a standstill for a little more than two months, …

Plasmonically-Enhanced Dna-Rna Hybrid-Based Bioassay For Amplification-Free Quantification Of Sars-Cov-2, Yuxiong Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Corona Virus Disease 2019 (COIVD-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly infectious respiratory illness. Within just a few months, it spread around the whole world and became a global pandemic. Real-time reverse-transcription polymerase chain reaction (RT-PCR) works as a gold standard method diagnosing COVID-19 with high sensitivity and specificity. But due to the programs of RT-PCR, it usually takes more than 24 hours to get the results while specialized devices are also required. False-negative results can happen as well using RT-PCR which increase the risk of spreading coronavirus. To promote quicker detection of COVID-19, …

Consultation/Liaison Psychiatry During Covid-19, Robert Frierson, Steven B Lippmann

The University of Louisville Journal of Respiratory Infections

Consultation/liaison psychiatrists care for people with co-existing medical and psychologic difficulties. The coronavirus pandemic is stressful for patients and their psychiatric caregivers. Patients have lost support systems and harbor fears about exposing family to the virus. COVID-19 sometimes exacerbates previous psychiatric conditions, while diminishing intimacy with physicians. Everyone is oversaturated with COVID-19-related news focusing on rising concerns about the illness and about jobs, school, and housing insecurities.

The psychiatrist maintains a hospital presence despite fear of contracting the disease. Challenges include addressing staff morale, evidencing empathy despite telecommunication devices, and treating anxiety, depression, sleep phobias, post intubation flashbacks, COVID-19-induced cognitive …

Legal And Ethical Implications Of U.S. And Canadian Vaccine Contracts: The Impact Of Vaccine Nationalism On The Global Pandemic Response, Ryan S. Tahiri

University of Miami Inter-American Law Review

This note explores the COVID-19 vaccine contracts between the U.S. and Canada and the impact of these types of agreements on the global pandemic response. These “pre-purchases,” many of which were executed before the development of a vaccine, have afforded a select few nations the opportunity to stockpile vaccines, while other nations with fewer resources are unable to secure any doses. An effective method to counter the effects of the pandemic is the creation of a global vaccine network that provides equitable access to vaccine doses for nations in need. COVAX was launched to ensure that lower and middle-income nations …
