Respiratory disease, attributed to influenza, respiratory syncytial virus (RSV), and SARS-CoV-2, was reported nationally during the 2023/2024 respiratory viral season. The emergence of novel SARS-CoV-2 variants was considered a significant factor contributing to the rise in COVID-19 cases. Data from the Johns Hopkins Hospital System (JHHS) showed that enterovirus/rhinovirus had also been circulating at high rates.

Avian influenza poses a severe threat to poultry production and global food security, prompting the development of vaccination programs in numerous countries. Modified live virus (MLV) vaccines, with their potential for mass application, offer a distinct advantage over existing options. However, concerns surrounding reversion, recombination, and unintended transmission have hindered the progress of MLV development for avian influenza in poultry.

Background: Despite historical and contemporary trauma, American Indian and Alaska Native (AIAN; Indigenous) communities responded with resilience to the COVID-19 pandemic. However, AIANs experienced disproportionate rates of infection, hospitalization, death, and reduced life expectancy. School closures exacerbated disparities, leading to learning loss, economic instability, and mental health challenges among AIAN youth.

Introduction: Disrupted sleep is common in individuals with Alzheimer's disease (AD) and may be a marker for AD risk. The timing of sleep affects sleep-wake activity and is also associated with AD, but little is known about links between sleep architecture and the midpoint of sleep in older adults. In this study, we tested if the midpoint of sleep is associated with different measures of sleep architecture, AD biomarkers, and cognitive status among older adults with and without symptomatic AD.

Aim: The aim of the study is to determine the difference in the shear bond strengths to dentin among dental composite (Filtek Z350®, 3M), compomer (Dyract Flow®, Dentsply) and Giomer (Beautifil®, Shofu) with 3M Single Bond Universal Adhesive (SBU) (7th generation, self-etch, single solution adhesive) and Adper Single Bond 2 Adhesive (ASB) (5th generation, total-etch, two solution adhesive).

Materials And Methods: Sixty extracted human permanent teeth were collected, cleansed of debris, and placed in distilled water. The samples were segregated into two groups depicting the two bonding agents-Adper (ASB) and 3M Single Bond Universal (SBU) and sub-grouped into three groups depicting the three restorative materials (Composite, Giomer, and Compomer) used.

Background: Venous thromboembolism risk increases in hospitals due to reduced patient mobility. However, initial mobility evaluations for thromboembolism risk are often subjective and lack standardization, potentially leading to inaccurate risk assessments and insufficient prevention.

Methods: A retrospective study at a quaternary academic hospital analyzed patients using the Padua risk tool, which includes a mobility question, and the Johns Hopkins-Highest Level of Mobility (JH-HLM) scores to objectively measure mobility.

Variant mutation in SARS-CoV-2 nucleocapsid enhances viral infection via altered genomic encapsidation.

bioRxiv

March 2024

Department of Microbiology and Molecular Genetics, Robert Larner, M.D. College of Medicine, University of Vermont, Burlington VT, 05405, USA.

Article Synopsis
  • - The study focuses on how mutations in SARS-CoV-2 variants, particularly the Delta variant, can help us understand both the virus's biology and the public health impact of these changes.
  • - Researchers identified a specific mutation (G215C) in the nucleocapsid (N) protein that creates a disulfide bond, leading to more stable protein structures (dimers) which enhance viral growth.
  • - The G215C mutation also results in the production of larger virions that contain more nucleocapsid proteins, indicating a potential impact on how the virus spreads.

Article Synopsis
  • The study aims to forecast the age distribution of people living with HIV (PWH) in Kenya from 2025 to 2040, focusing on how HIV services impact these trends.
  • Using a compartmental model based on historical data, researchers predicted changes in both population size and age distribution of new infections and PWH, with two scenarios: status quo and increased service scale-up.
  • Results showed that without enhanced services, new infections would decline slightly, while the median age of PWH would rise; however, significant improvements in HIV services could lead to a dramatic reduction in new infections by 2040 and a higher percentage of older PWH.

Objective: While diet plays a key role in chronic kidney disease (CKD) management, the potential for diet to impact CKD prevention in the general population is less clear. Using a priori knowledge, we derived disease-related dietary patterns (DPs) through reduced rank regression (RRR) and investigated associations with kidney function, separately focusing on generally healthy individuals and those with self-reported kidney diseases, hypertension, or diabetes mellitus.

Methods: Eight thousand six hundred eighty-six participants from the population-based Cooperative Health Research in South Tyrol study were split into a group free of kidney disease, hypertension and diabetes (n = 6,133) and a group with any of the 3 conditions (n = 2,553).
