Integrating Conformational Dynamics And Perturbation-Based Network Modeling For Mutational Profiling Of Binding And Allostery In The Sars-Cov-2 Spike Variant Complexes With Antibodies: Balancing Local And Global Determinants Of Mutational Escape Mechanisms, Gennady M. Verkhivker, Steve Agajanian, Ryan Kassab, Keerthi Krishnan

Mathematics, Physics, and Computer Science Faculty Articles and Research

n this study, we combined all-atom MD simulations, the ensemble-based mutational scanning of protein stability and binding, and perturbation-based network profiling of allosteric interactions in the SARS-CoV-2 spike complexes with a panel of cross-reactive and ultra-potent single antibodies (B1-182.1 and A23-58.1) as well as antibody combinations (A19-61.1/B1-182.1 and A19-46.1/B1-182.1). Using this approach, we quantify the local and global effects of mutations in the complexes, identify protein stability centers, characterize binding energy hotspots, and predict the allosteric control points of long-range interactions and communications. Conformational dynamics and distance fluctuation analysis revealed the antibody-specific signatures of protein stability and flexibility of the …

A Case Of Pleural Tuberculosis Vs Latent Tuberculosis Reactivation As A Result Of Covid-19 Infection And Treatment, Wesley Tang, Lex Leonhardt, Aamir Pervez, Satish Sarvepalli

Journal of Community Hospital Internal Medicine Perspectives

The reactivation of latent tuberculosis occurs when a patient living with Mycobacterium tuberculosis enters a state where the immune system is suppressed. Since early 2021, the standard of care has been to provide corticosteroids in patients with COVID-19 infection in hospitalized patients receiving supplemental oxygen or mechanical ventilation. The immunomodulatory effects of corticosteroids are potentially detrimental for patients with latent vs active tuberculosis, with concomitant SARS-CoV2 infection. We present one of the first few cases in the literature detailing a case of reactivation of latent tuberculosis vs. pleural tuberculosis as a consequence of COVID-19, and who underwent subsequent corticosteroid treatment.

Journal of Community Hospital Internal Medicine Perspectives

Multisystem inflammatory syndrome is a life-threatening condition associated with elevated inflammatory markers and multiple organ injury. A diagnosis of exclusion, it has been reported after severe acute respiratory syndrome coronavirus 2 infection (SARS-CoV-2) in children and adults; recently it has been described in some post-COVID-19 vaccinated individuals. The prognosis with supportive care and immunomodulatory therapy is good, although some individuals may require treatment in the intensive care unit (ICU). Here we report a case of a 58-year-old man who developed multi-organ failure after receiving the second dose of the Moderna mRNA-1273 COVID-19 vaccine. He required critical organ support in the …

A Pilot Phase Ib/Ii Study Of Whole-Lung Low Dose Radiation Therapy (Ldrt) For The Treatment Of Severe Covid-19 Pneumonia: First Experience From Africa, Mansoor Saleh, Karishma Sharma, Jasmit Shah, Farrok Karsan, Angela Waweru, Martin Musumbi, Reena Shah, Shahin Sayed, Innocent Abayo, Noureen Karimi, Stacey Gondi, Sehrish Rupani, Grace Kirathe, Heldah Amariati

Internal Medicine, East Africa

Background: Low dose radiation therapy (LDRT) has been used for non-malignant conditions since early 1900s based on the ability of single fractions between 50–150 cGy to inhibit cellular proliferation. Given scarcity of resources, poor access to vaccines and medical therapies within low and middle income countries, there is an urgent need to identify other cost-effective alternatives in management of COVID-19 pneumonia. We conducted a pilot phase Ib/II investigator-initiated clinical trial to assess the safety, feasibility, and toxicity of LDRT in patients with severe COVID-19 pneumonia at the Aga Khan University Hospital in Nairobi, Kenya. Additionally, we also assessed clinical …

Conscious And Unconscious Bias: The Hidden Pandemic Of Biases In Healthcare Exacerbated By Covid-19, Ibtisam Rauf, Abigail Hartmann, Alexandre Koumtchev, Syed Anjum Khan, Rahul Kashyap

HCA Healthcare Journal of Medicine

Background

There are limited data on unconscious bias in healthcare, but there is consistent evidence that it alters clinical decision-making. COVID-19 exacerbated many pre-existing disparities, and this paper seeks to identify, deconstruct, and propose mitigation strategies for a few of them.

Discussion

Five of the largest disparities amplified by the pandemic are discussed in this paper. Older people, Black people, uninsured people, rural communities, and people with lower education levels have been disproportionally affected in both morbidity and mortality.

Conclusions

The disparities discussed above did not occur in a vacuum but are the result of systemic issues. Equity starts with …

Is There A Bias Toward Unvaccinated Covid-19 Patients?, Abbas B. Jama, Anwar Khedr, Hisham Mushtaq, Nitesh K. Jain, Thoyaja Koritala, Syed Anjum Khan

HCA Healthcare Journal of Medicine

With more than 22% of the United States still not vaccinated for COVID-19, we are trying to shed some light on whether there is any bias when treating unvaccinated COVID-19 patients. We highlight several reports where some individuals or organizations displayed possible bias, whether implicit or explicit. We examine the legal and ethical implications of these biases and offer a general overview of how to tackle them.

Viral Infections In Pakistan: Prevalence, Factors Affecting Spread, And Recommendations For Control, Zehra Naseem, Maaha Ayub, Sharaf Ali Shah, Syed Asad Ali, Syed Hani Abidi

Medical College Documents

Pakistan is endemic to a number of viral infections, owing to its humid climate, topographical variation, soaring population, and lack of education and awareness. These viruses may have several different modes of transmission, including respiratory or airborne transmission, sexual transmission, blood-borne, fecal-oral transmission, vector-borne transmission, and transmission following an organ transplant. Although several different microorganisms are responsible for causing these infections, a few viruses are found more commonly in Pakistan and are primarily responsible for causing infections. In this study, we present a review of the most recent studies on different viruses, transmitted through various transmission routes, found commonly in …

The 10-valent pneumococcal vaccine was introduced in Pakistan's Expanded Program on Immunization (EPI) in 2013 as a 3 + 0 schedule without catchup. We conducted three annual cross-sectional surveys from 2014-2016 to measure vaccine-type (VT) carriage in infants from a rural part of Pakistan. Nasopharyngeal specimens were collected by random sampling of infants from two union councils of Matiari. Samples were then transported to the Infectious Disease Research Laboratory (IDRL) at the Aga Khan University within 6-8 h of collection. Serotypes were established using sequential multiplex PCR. Of the 665 children enrolled across three surveys, 547 were culture-positive for pneumococcus. …

Rural-Urban And Within-Rural Differences In Covid-19 Mortality Rates, Yue Sun, Kent Jason G. Cheng, Shannon M. Monnat

Journal of Rural Social Sciences

Since late-2020, COVID-19 mortality rates have been higher in rural than in urban America, but there has also been substantial within-rural heterogeneity. Using CDC data, we compare COVID-19 mortality rates across the rural-urban continuum as well as within rural counties across different types of labor markets and by metropolitan adjacency. As of October 1, 2021, the cumulative COVID-19 mortality rate was 247.0 per 100,000 population in rural counties compared to 200.7 in urban counties. Higher COVID-19 mortality rates in rural counties are explained by lower average educational attainment and lower median household income. Within rural counties, mortality rates have been …

The single-stranded viral RNA (ssvRNA) known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 can be effectively inactivated by a number of natural ribonucleic acid-based host cell defenses. One of the most important of these defenses includes the actions of a class of small non-coding RNAs (sncRNAs) known as microRNAs (miRNAs). Via base-pair complementarity miRNAs are capable of specifically targeting ssvRNA sequences such as SARS-CoV-2 promoting its inactivation and neutralization. RNA-sequencing and bioinformatics analysis indicate that multiple naturally-occurring human miRNAs have extensive complementarity to the SARS-CoV-2 ssvRNA genome. Since miRNA abundance, speciation, and complexity vary significantly …
