Single-Cell Transcriptomics Reveals Pre-Existing Covid-19 Vulnerability Factors In Lung Cancer Patients, Wendao Liu, Wenbo Li, Zhongming Zhao

Journal Articles

UNLABELLED: Coronavirus disease 2019 (COVID-19) and cancer are major health threats, and individuals may develop both simultaneously. Recent studies have indicated that patients with cancer are particularly vulnerable to COVID-19, but the molecular mechanisms underlying the associations remain poorly understood. To address this knowledge gap, we collected single-cell RNA-sequencing data from COVID-19, lung adenocarcinoma, small cell lung carcinoma patients, and normal lungs to perform an integrated analysis. We characterized altered cell populations, gene expression, and dysregulated intercellular communication in diseases. Our analysis identified pathologic conditions shared by COVID-19 and lung cancer, including upregulated TMPRSS2 expression in epithelial cells, stronger inflammatory …

Some viruses restructure host chromatin, influencing gene expression, with implications for disease outcome. Whether this occurs for SARS-CoV-2, the virus causing COVID-19, is largely unknown. Here we characterized the 3D genome and epigenome of human cells after SARS-CoV-2 infection, finding widespread host chromatin restructuring that features widespread compartment A weakening, A-B mixing, reduced intra-TAD contacts and decreased H3K27ac euchromatin modification levels. Such changes were not found following common-cold-virus HCoV-OC43 infection. Intriguingly, the cohesin complex was notably depleted from intra-TAD regions, indicating that SARS-CoV-2 disrupts cohesin loop extrusion. These altered 3D genome/epigenome structures correlated with transcriptional suppression of interferon response genes …

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 …

School of Medicine Faculty Publications

The severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19, possesses an unusually large positive-sense, single-stranded viral RNA (ssvRNA) genome of about ~29,903 nucleotides (nt). In many respects, this ssvRNA resembles a very large, polycistronic messenger RNA (mRNA) possessing a 5′-methyl cap (m7GpppN), a 3′- and 5′-untranslated region (3′-UTR, 5′-UTR), and a poly-adenylated (poly-A+) tail. As such, the SARS-CoV-2 ssvRNA is susceptible to targeting by small non-coding RNA (sncRNA) and/or microRNA (miRNA), as well as neutralization and/or inhibition of its infectivity via the human body’s natural complement of about ~2650 miRNA species. Depending on host cell and tissue …

Hyaluronan In The Pathogenesis Of Acute And Post-Acute Covid-19 Infection, Henry W Barnes, Sally Demirdjian, Naomi L Haddock, Gernot Kaber, Hunter A Martinez, Nadine Nagy, Harry Karmouty-Quintana, Paul L Bollyky

Journal Articles

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recently emerged as the cause of a global pandemic. Infection with SARS-CoV-2 can result in COVID-19 with both acute and chronic disease manifestations that continue to impact many patients long after the resolution of viral replication. There is therefore great interest in understanding the host factors that contribute to COVID-19 pathogenesis. In this review, we address the role of hyaluronan (HA), an extracellular matrix polymer with roles in inflammation and cellular metabolism, in COVID-19 and critically evaluate the hypothesis that HA promotes COVID-19 pathogenesis. We first provide a brief overview of COVID-19 infection. …

Post Covid-19 Cognitive Impairment In A Patient With Bipolar Disorder, Nilanjana Dutta, Raghav Gupta, Dr. M Kishor Mbbs, Md

Digital Journal of Clinical Medicine

COVID-19 has caused widespread health conditions, psychological and social distress among people and there is evidence that shows profound neuropsychiatric complications during acute and post-recovery phases of the infection. Cognitive impairment occurring after COVID-19 infection can be explained by various mechanisms, including persistent systemic inflammation, direct viral invasion, alteration in the blood-brain barrier, and cerebrovascular endothelial injury.There are few studies that have explored the impact of COVID-19 on pre-existing psychiatric conditions. This case report highlights the temporal association of cognitive impairment with COVID-19 and the need for cognitive assessment and management in post-COVID-19 patients with pre-existing psychiatric conditions.

Objective

To characterize management and outcomes of seizures, status epilepticus, and cortical myoclonus in COVID-19, with individual patient data analysis of published literature.

Methods

Systematic literature review was conducted in accordance with PRISMA guidelines. Criteria included new-onset seizures, status epilepticus, and/or cortical myoclonus with concomitant COVID-19. COVID-19 severity was dichotomized into mild and severe cases. Good outcome was defined as discharge without severe deficits, and/or return to baseline.

Results

A total of 105 studies reporting 176 patients (male 56.3%;mean age 47.8,SD 25.6) were included. Status epilepticus occurred in 47 patients (26.7%) and myoclonus in 41 (23.3%). Severe COVID-19 occurred in …

Medical Student Research Symposium

Background: Despite more than 60% of the United States population being fully vaccinated, COVID-19 cases continue to spike in a temporal pattern. These patterns in COVID-19 incidence and mortality may be linked to short-term changes in environmental factors.

Methods: Nationwide, county-wise measurements for COVID-19 cases and deaths, fine-airborne particulate matter (PM2.5), and maximum temperature were obtained from March 20, 2020 to March 20, 2021. Multivariate Linear Regression was used to analyze the association between environmental factors and COVID-19 incidence and mortality rates in each season. Negative Binomial Regression was used to analyze daily fluctuations of COVID-19 cases …

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 …
