COVID-19: A 2020 update

Interaction of Biochemical Processes between Chronic Obstructive Pulmonary Disease (COPD), Pulmonary Arterial Hypertension (PAH), and Coronavirus Disease 2019 (COVID-19)

Both pulmonary arterial hypertension (PAH) and chronic obstructive pulmonary disease (COPD) are risk factors for coronavirus disease 2019 (COVID-19). Patients with lung injury and altered pulmonary vascular anatomy or function are more susceptible to infections. The purpose of the study is to ascertain whether individuals with COPD or PAH are affected synergistically by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Data sources for the construction of a protein-protein interaction (PPI) network and the identification of differentially expressed genes (DEGs) included three RNA-seq datasets from the GEO database (GSE147507, GSE106986, and GSE15197). Then, relationships between miRNAs, common DEGs, and transcription factor (TF) genes were discovered. Functional analysis using Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and other databases, as well as the forecasting of antiviral medications for COPD and PAH patients infected with SARS-CoV-2, were also performed. Eleven common DEGs were found in the three datasets, and their biological functions were primarily enriched in the control of protein modification processes, particularly phosphorylation. Growth factor receptor binding reflects molecular function. KEGG analysis indicated that co-DEGs mainly activate Ras, and PI3K-Akt signaling pathways and act on focal adhesions. NFKB1 interacted with HSA-miR-942 in the TF-miRNA-DEGs synergistic regulatory network. Acetaminophen is considered an effective drug candidate. There are some connections between COPD and PAH and the development of COVID-19. This research could aid in developing COVID-19 vaccines and medication candidates that would work well as COVID-19 therapies.

Community care for COVID-19 in the constraint resources is the need of the hour to provide health facility to the last man of the queue

In COVID era, the developing countries like India are facing big problems and fail to provide health care to needy patients. The main reason for this failure is limited health resources and overpopulated states. Considering these, it is need of the hour to establish community care for COVID-19 in every district. The trained health worker will be instrumental in categorizing COVID-positive patients in three different zones that are green, yellow, or red on the basis of mild, moderate, or severe clinical symptoms, respectively. All such patients may be treated under the guidance of doctors of the telemedicine department of the tertiary center with close monitoring under CCTV camera and other telemedicine software. The only limitation of this model is that we need to shift sick patients (red) to higher center. The estimated cost is approximately 2,29,000 only to establish one center.

Updated insight into COVID-19 disease and health management to combat the pandemic

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19 disease in humans and is the responsible viral agent for the currently ongoing pandemic. Early cases of COVID-19 were reported from Wuhan, Hubei province of China, the likely birthplace of this outbreak. Currently, over 92 million people in the globe are actively battling this virus, and over 2 million individuals have already succumbed to the disease. The high human-to-human transmission capacity of the virus is among the primary causes for such a rapid global spread of COVID-19. In humans, it causes acute to severe respiratory distress in the form of pneumonia. The presentation of clinical features of the disease ranges from mild in healthy adults to severe among individuals with weakened or immunocompromised immune systems and the elderly. Thus, increasing patient cases of COVID-19 warrants a growing demand for medical attention that is eventually overburdening our health care systems. Rapid detection of COVID-19 in suspected individuals and isolation are among the crucial intervention norms in health management strategies to control the COVID-19 pandemic, in addition to strict observance of public hygienic practices such as reduced public gathering, use of facial masks, and practicing of social distancing. This chapter provides an overview of the epidemiology of COVID-19 and the current classical health management strategies and issues to tackle this pandemic. It particularly highlights the role of standard as well as novel biomolecular diagnostic techniques as a tool for successful implementation of such public safety measures issued by medical policy makers and the governing bodies.

Managing Patients in the COVID-19 Pandemic: A Virtual Multidisciplinary Approach

Objective

To study the impact of a 60-day pilot of an innovative virtual-care model using general internal medicine physicians and nurses to respond rapidly to more than 1200 coronavirus disease-2019 (COVID-19)-positive nasopharyngeal polymerase chain reaction tests.

Patients and Methods

The current study was approved by the Mayo Clinic COVID-19 Research Committee and the Mayo Clinic Institutional Review Board. The data for all SARS-CoV-2–positive patients treated by our team were entered into a prospectively maintained internal research electronic data capture database. We searched this database retrospectively for the first 60 days of our program (March 23, 2020 to May 22, 2020). The data included basic deidentified demographics; symptoms at intake into the program; date of symptom onset; risk factors; location; and outcomes including hospitalization, admission to intensive care unit, and death.

Results

Patients were contacted, on average, 6.3 hours after their results became available. There was a total of 138 ED visits. Of these, 40% were admitted to the hospital, with 36% of those admitted requiring intensive care unit level of care. Of the 849 patients in this sample, there were only 2 deaths (0.23%) at 60 days.

Conclusion

Our innovative multidisciplinary COVID team provided excellent clinical care for patients with COVID, with a very low mortality rate compared with the national average. Although data are not available on a national scale for time to contact patient, our team was able to contact patients within the established recommendation for contact within 48 hours of testing, which is optimal.
