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 …

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 …

A Predictive Model For Geographical Location Using Microbiome Composition And Covid-19 Based Analysis, Ahmed Adel Aboushanab

Theses and Dissertations

The human microbiome is a main contributor for the health and welfare of the human body. It is affected by many factors like diet and hygiene. These factors differ between different populations. 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 …

The Covid-19 Pandemic: The New Way Of Living, Anonymous

Community Reflections

The coronavirus came to America in the beginning of the year, 2021. My contribution is based on the virus's peak and how it affected my family. My essay ranges from what life was like as a high school student in New York witnessing the pandemic to my family being exposed. It touches on the important features of being in lockdown and the adjustment society had to make that still exists today. A common theme throughout my assessment is the development of fear from the coronavirus. It discusses how fear has driven many of the restrictions that my community has had …

Clinical Outcomes Of Immunomodulatory Therapies In The Management Of Covid-19: A Tertiary-Care Experience From Pakistan, Noreen Nasir, Salma Tajuddin, Sarah Khaskheli, Naveera Khan, Hammad Niamatullah, Nosheen Nasir

Section of Internal Medicine

The pharmacological management of COVID-19 has evolved significantly and various immunomodulatory agents have been repurposed. However, the clinical efficacy has been variable and a search for cure for COVID-19 continues. A retrospective cohort study was conducted on 916 patients hospitalized with polymerase chain reaction (PCR)-confirmed COVID-19 between February 2020 and October 2020 at a tertiary care academic medical center in Karachi, Pakistan. The median age was 57 years (interquartile range (IQR) 46–66 years). The most common medications administered were Methylprednisolone (65.83%), Azithromycin (50.66%), and Dexamethasone (46.6%). Majority of the patients (70%) had at least two or more medications used in …

Prevalence Of Infectious Diseases Among 6078 Individuals With Down Syndrome In The United States, Veronica Fitzpatrick, Anne Rivelli, Sagar Chaudhari, Laura Chicoine, Gengjie Jia, Andrey Rzhetsky, Brian Chicoine

Journal of Patient-Centered Research and Reviews

A recent disease prevalence study of the largest documented Down syndrome (DS) cohort in the United States strongly suggested significant disparity in general infectious disease conditions among individuals with DS versus those without DS. In this follow-up retrospective analysis, we explored these differences in greater detail by calculating prevalence of 52 infectious diseases, across 28 years of data among 6078 individuals with DS and 30,326 age- and sex-matched controls, abstracted from electronic medical records within a large Midwestern health system. We found that the DS cohort had higher prevalence of pneumonias (including aspiration, viral, bacterial, pneumococcal, and unspecified/atypical); otitis externa; …

Numeracy And Financial Wellbeing During The Covid-19 Pandemic, Nora Wikoff

Numeracy

This paper examines the role of numeracy in smoothing financial difficulties during the COVID-19 pandemic. The results show that numeracy was associated with a 30% reduction in late or non-payment of bills and a 20% reduction in the odds of feeling financially squeezed. The effect of numeracy on financial wellbeing was remarkably consistent across levels of education, ethnicity, and gender, suggesting that improving numeracy levels in the population may be an effective strategy to increase financial capability across the board. However, while numerate individuals were less likely to experience financial difficulty, high numeracy did not predict narrower gaps between Whites …
