The impact of sleep and exercise on brain atrophy in mild cognitive impairment.

Chronic sleep deprivation and lack of physical exercise may have detrimental effects on overall health, particularly in terms of brain health, with significant implications for cognitive function and well-being. This review explores the impact of chronic sleep deprivation and physical exercise on brain atrophy in mild cognitive impairment (MCI) and Alzheimer's disease (AD). Drawing insights from 40 selected studies, the review synthesizes evidence on these lifestyle factors' correlations with neurodegenerative changes.

Systematic assessment of COVID-19 host genetics using whole genome sequencing data.

Courses of SARS-CoV-2 infections are highly variable, ranging from asymptomatic to lethal COVID-19. Though research has shown that host genetic factors contribute to this variability, cohort-based joint analyses of variants from the entire allelic spectrum in individuals with confirmed SARS-CoV-2 infections are still lacking. Here, we present the results of whole genome sequencing in 1,220 mainly vaccine-naïve individuals with confirmed SARS-CoV-2 infection, including 827 hospitalized COVID-19 cases.

increases HSV-2 infection by decreasing vaginal barrier integrity and increasing inflammation .

Introduction: Clinically, a dysbiotic vaginal microbiota (VMB) colonized with anaerobic species such as has been linked to increased susceptibility to viral sexually transmitted infections (STIs) such as Herpes Simplex Virus Type 2 (HSV-2). The mechanism is poorly understood due to the lack of small animal models.

Methods: Mice were inoculated with 10 CFU of the eubiotic bacteria , the dysbiotic bacteria , or PBS as a negative control every 48 h for ten days.

Fertility and abortion: A population-based comparison between women with cancer and those in childbearing age.

Objectives: Concurrence of pregnancy and cancer diagnosis is increasingly frequent in Italy. The study aimed to compare women with pregnancy-associated cancers (PACs) to those of childbearing age, focusing on fertility, induced abortion, and miscarriage.

Methods: The population-based study included women aged 15-49 years, both with and without PAC, who were residents in the area covered by the 19 participating Cancer Registries between 2003 and 2015 and identified by individual deterministic linkage with the Hospital Discharge Database.
