Covid-19-Associated Myocarditis: Screening For Early Diagnosis, Yousuf Khan, Salmman Ahmed, Samuel John Wlasowicz, Ronald G. Lott Iii, Xavier C. Zonna

Advances in Clinical Medical Research and Healthcare Delivery

The SARS-CoV-2 virus (causing COVID-19), has infected about 770 million people, and caused the death of about 6.9 million people worldwide in the span of three years (John Hopkins Resource Center). Common symptoms of a patient infected with the virus include shortness of breath, fever, chills, fatigue, loss of taste or smell, and muscle aches. However, recent studies have also shown a prevalence of patients presenting with cardiac inflammation (endocarditis, myocarditis or pericarditis) as a potential comorbidity, both during the infectious stage as well as after the infection has subsided. A pattern of specific clinical markers may be indicative of …

Acute Neutrophilic Vasculitis (Leukocytoclasia) In 36 Covid-19 Autopsy Brains, Roy H. Rhodes, Gordon L. Love, Fernanda Da Silva Lameira, Maryam Sadough Shahmirzadi, Sharon E. Fox, Richard S. Vander Heide

School of Medicine Faculty Publications

Background: Hypercytokinemia, the renin-angiotensin system, hypoxia, immune dysregulation, and vasculopathy with evidence of immune-related damage are implicated in brain morbidity in COVID-19 along with a wide variety of genomic and environmental influences. There is relatively little evidence of direct SARS-CoV-2 brain infection in COVID-19 patients. Methods: Brain histopathology of 36 consecutive autopsies of patients who were RT-PCR positive for SARS-CoV-2 was studied along with findings from contemporary and pre-pandemic historical control groups. Immunostaining for serum and blood cell proteins and for complement components was employed. Microcirculatory wall complement deposition in the COVID-19 cohort was compared to historical control cases. Comparisons …

An Unusual Case Of Hemophagocytic Lymphohistiocytosis Associated With Mycobacterium Chimaera Or Large-Cell Neuroendocrine Carcinoma, Tejaswi Venigalla, Sheila Kalathil, Meena Bansal, Mark Morginstin, Vinicius Jorge, Patricia Perosio

Einstein Health Papers

Hemophagocytic lymphohistiocytosis (HLH) is a rare and very dangerous condition characterized by abnormal activation of the immune system, causing hemophagocytosis, inflammation, and potentially widespread organ damage. The primary (genetic) form, caused by mutations affecting lymphocyte cytotoxicity, is most commonly seen in children. Secondary HLH is commonly associated with infections, malignancies, and rheumatologic disorders. Most current information on diagnosis and treatment is based on pediatric populations. HLH is a disease that should be diagnosed and treated promptly, otherwise it is fatal. Treatment is directed at treating the triggering disorder, along with symptomatic treatment with dexamethasone and etoposide. We present a 56-year-old …

A Single Dose Of The Deactivated Rabies-Virus Vectored Covid-19 Vaccine, Coravax, Is Highly Efficacious And Alleviates Lung Inflammation In The Hamster Model, Drishya Kurup, Christoph Wirblich, Leila Zabihi Diba, Rachael Lambert, Megan Watson, Noor Shaikh, Holly Ramage, Charalambos Solomides, Matthias J Schnell

Without sufficient herd immunity through either vaccination or natural infection, the coronavirus disease 2019 pandemic is unlikely to be controlled. Waning immunity with the currently approved vaccines suggests the need to evaluate vaccines causing the induction of long-term responses. Here, we report the immunogenicity and efficacy of our adjuvanted single-dose Rabies-vectored SARS-CoV-2 S1 vaccine, CORAVAX, in hamsters. CORAVAX induces high SARS-CoV-2 S1-specific and virus-neutralizing antibodies (VNAs) that prevent weight loss, viral loads, disease, lung inflammation, and the cytokine storm in hamsters. We also observed high Rabies VNA titers. In summary, CORAVAX is a promising dual-antigen vaccine candidate for clinical evaluation …

D-Dimer Levels And Acute Pulmonary Embolism Development In Covid-19 Patients, Vural Ahmet, Kahraman Ahmet Nedim

Journal of Mind and Medical Sciences

Objective. To identify those who develop pulmonary embolism with Ddimer levels by evaluating pulmonary CT angiographies of patients who are followed up with suspicion of coronavirus disease 2019 (COVID-19). Methods. Patients who were followed up in a community hospital with suspicion of COVID-19 and underwent Pulmonary CT angiography examination were evaluated. Clinical and demographic parameters and DDimer values for patients with and without pulmonary embolism were evaluated in the pulmonary CT angiogram. Results. During the COVID-19 pandemic, Thorax CT examination was performed in our center for suspicion or follow-up of COVID-19 infection in 3396 patients. Pulmonary CT angiography was applied …

High Prevalence Of Pre-Existing Serological Cross-Reactivity Against Severe Acute Respiratory Syndrome Coronavirus-2 (Sars-Cov-2) In Sub-Saharan Africa, For Yue Tso, Salum J. Lidenge, Phoebe B. Peña, Ashley A. Clegg, John R. Ngowi, Julius Mwaiselage, Owen Ngalamika, Peter Julius, John T. West, Charles Wood

Nebraska Center for Virology: Faculty Publications

Objective: Significant morbidity and mortality have occurred in the USA, Europe, and Asia due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), whereas the numbers of infections and deaths in sub-Saharan Africa (SSA) have remained comparatively low. It has been hypothesized that exposure of the population in SSA to other coronaviruses prior to the COVID-19 pandemic resulted in some degree of cross-protection against SARS-CoV-2 infection and pathogenesis. We evaluated this hypothesis by comparing SARS-CoV-2 cross-reactive antibodies in pre-pandemic plasma samples collected from SSA and the USA.

Method: Pre-COVID-19 pandemic plasma samples from SSA and the USA were collected and tested by …
