Compliance With Guidelines For Treatment Of Staphylococcus Aureus Bacteremia Is Associated With Decreased Mortality In Patients Hospitalized For Community-Acquired Pneumonia With Staphylococcus Aureus Bacteremia, Leslie Beavin, Vidyulata Salunkhe, Shashvin Singh, Ahmed Gana, Balaji Sekaran, Mahder A. Tella, Stephen P. Furmanek, Forest W. Arnold

The University of Louisville Journal of Respiratory Infections

Introduction: Staphylococcus aureus bacteremia has a minimum treatment duration of two weeks, while S. aureus community-acquired pneumonia (CAP) treatment is at least five days. Treatment failure, persistent bacteremia, and recurrence are common among patients with community-acquired S. aureus bacteremia. There is conflicting information in the current Infectious Diseases Society of America (IDSA) guidelines for the treatment of S.aureus bacteremia patients with CAP. Therefore, the appropriate treatment duration and modality for S. aureus CAP with bacteremia is unclear. The objective of this study was to compare outcomes among patients with S. aureus CAP and bacteremia treated in compliance versus non-compliance with …

Allosteric Determinants Of The Sars-Cov-2 Spike Protein Binding With Nanobodies: Examining Mechanisms Of Mutational Escape And Sensitivity Of The Omicron Variant, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

Structural and biochemical studies have recently revealed a range of rationally engineered nanobodies with efficient neutralizing capacity against the SARS-CoV-2 virus and resilience against mutational escape. In this study, we performed a comprehensive computational analysis of the SARS-CoV-2 spike trimer complexes with single nanobodies Nb6, VHH E, and complex with VHH E/VHH V nanobody combination. We combined coarse-grained and all-atom molecular simulations and collective dynamics analysis with binding free energy scanning, perturbation-response scanning, and network centrality analysis to examine mechanisms of nanobody-induced allosteric modulation and cooperativity in the SARS-CoV-2 spike trimer complexes with these nanobodies. By quantifying energetic and allosteric …

“Hiccups” With Covid-19 Management, Yong W. Lee, Jacob Psomiadis, Sarah Akbani, Marvin Lopez-Medal, Aisha Miller

Advances in Clinical Medical Research and Healthcare Delivery

Hiccups, medically referred as singultus, is a condition that results from involuntary contraction of the diaphragm and intercostal muscles. Singultus is usually a self-limiting condition which typically lasts less than 48 hours but in rare cases, can persist greater than 48 hours. This is a case of a 48 year-old male who was prescribed dexamethasone for COVID-19 but developed intractable singultus for two weeks. Patient was unable to tolerate diet due to intractable singultus leading to vomiting. He underwent various non-pharmacological maneuvers and pharmacotherapy without resolution. Dexamethasone- induced hiccups have been reported as an under recognized side effect of dexamethasone. …

If I could tell only one thing to future generations about the hardships of the pandemic, I would tell them that no one thing in life is permanent. Things you could never imagine being temporary can be taken from you in an instant. The pandemic has taught me how to adapt during difficult times.

The Connecticut Governor’s state-wide mask mandate for K-12 schools is set to expire at the end of this month, leaving the decision up to local communities. Because the CDC still lists Fairfield County as a high-transmission area and, on the advice of state and local health officials, Sacred Heart will continue to require indoor masking for the time being.

Bishop, Luanne Didelot, William Hayden, Beverly Williams Coleman, Sarah Tan, Delanor Manson, Kellie Kane, Dawn Balcom, Paul Kern

The University of Louisville Journal of Respiratory Infections

Background: Response to the COVID-19 pandemic has required innovative approaches to vaccination, including methods to rapidly and safely immunize communities. A major challenge to such a response involved access to untapped healthcare worker resources. The Louisville, Kentucky, response involved the use of a large volunteer workforce to supplement local public health employees in planning and implementing a large-scale drive-through vaccination event. The objective of this manuscript was to outline processes involved in training a mass immunization workforce and implementating a large-scale COVID-19 community vaccination.

Approach: Competency-based and standardized training was provided for every volunteer before working their shift. Volunteers worked …

Life During The Covid-19 Pandemic Was, And Still Is, Dispiriting, Anonymous

Community Reflections

For me personally, I did not enjoy quarantining at all. I did enjoy seeing my family every day, however, I was very lonely. I couldn’t see any of my friends, which was very disappointing. Thankfully with social media I could facetime them and text them, but face-to-face contact with other people is very necessary; it is something you wouldn’t normally think is important, but when you are unable to physically be with other people, you realize how lonely you feel.

Background:

Imbalance in tryptophan (TRP) metabolism and its neuroactive metabolites, serotonin and kynurenine (KYN), is a known pathogenic mechanism underlying neurocognitive impairment. Gut microbiota plays an important role in TRP metabolism, and the production of these neuroactive molecules affects neurocognitive function. Although both HIV infection and normal aging independently induce gut dysbiosis and influence TRP metabolism, their interactive effects on compositional/functional changes in gut microbiota and consequent alterations in TRP metabolites remain largely undetermined.

Methods:

Older people living with HIV infection (PLWH, aged 50–70 years, n = 22) were enrolled in this cross-sectional pilot study. Metagenomic analysis of fecal microbiome …

Testing the population-microbiome differences using healthy samples from different countries is the first objective of this study. This data was then used in training and testing machine learning models (Random Forest and L2-logistic Regression Classifiers) for the prediction of the geographical location based on the microbiome data. Random Forest Classifier had the highest accuracy. Feature importance analysis showed that the data for Proteobacteria, Actinobacteria, and Bacteroidetes improved the …

Conformational Flexibility And Local Frustration In The Functional States Of The Sars-Cov-2 Spike B.1.1.7 And B.1.351 Variants: Mutation-Induced Allosteric Modulation Mechanism Of Functional Dynamics And Protein Stability, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

Structural and functional studies of the SARS-CoV-2 spike proteins have recently determined distinct functional states of the B.1.1.7 and B.1.351 spike variants, providing a molecular framework for understanding the mechanisms that link the effect of mutations with the enhanced virus infectivity and transmissibility. A detailed dynamic and energetic analysis of these variants was undertaken in the present work to quantify the effects of different mutations on functional conformational changes and stability of the SARS-CoV-2 spike protein. We employed the efficient and accurate coarse-grained (CG) simulations of multiple functional states of the D614G mutant, B.1.1.7 and B.1.351 spike variants to characterize …
