Immunoregulation of Ghrelin in neurocognitive sequelae associated with COVID-19: an in silico investigation
In this study, we explored, by bioinformatics approaches, the interaction between the multiple inflammatory agents involved in SARS-CoV-2 and Ghrelin (Ghre) together with its receptor GHSR-1A, which are described as anti-inflammatory mediators, in order to investigate what could trigger the hyper-inflammatory response in some SARS-CoV-2 patients. In our analysis, we found several interactions of Ghre and GHSR-1A with SARS-CoV-2 interacting human genes. We observed a correlation between Ghre, angiotensin-converting enzyme 2 ACE2, toll-like receptors 9 (TLR9), and Acidic chitinase (CHIA), whereas its receptor GHSR-1A interac...

Intra-plaque calcium and its relation with the progression of carotid atheromatous disease
CONCLUSIONS: These results suggest that a higher content of Ca confers greater stability against the progression of carotid AD and, eventually, its ability to generate symptomatology.PMID:35583455 | DOI:10.23736/S0392-9590.22.04872-6

Identifying factors contributing to increased susceptibility to COVID-19 risk: a systematic review of Mendelian randomization studies
ConclusionThis review summarizes modifiable factors for intervention (e.g. smoking, obesity and inflammatory factors) and proteomic signatures (e.g. OAS1 and IL-6) that could help identify drugs for treating COVID-19.

Daily Multivitamins Linked to Improved Cognition in Older People
Taking a daily multivitamin may improve cognitive function in older people, astudy inAlzheimer ’s& Dementia has found. Taking a cocoa supplement, however, does not appear to slow cognitive decline.“There is an urgent need to identify effective strategies to preserve cognitive function to mitigate the heavy societal burden associated with Alzheimer’s disease and related dementia, which affect more than 46 million people worldwide,” wrote Laura D. Baker, Ph.D., of Wake Forest University S chool of Medicine and colleagues. Cocoa extract is rich in compounds called flavanols, and previous small studies suggest that...

An Evidence-Based Review of Vitamin D for Common and High-Mortality Conditions
Conclusion: Prospective studies of vitamin D supplementation demonstrate variable impact on disease specific and patient-oriented outcomes, suggesting a correlation but not a causal relationship between low vitamin D levels and disease pathogenicity. Future research should determine dosing standards and timing of vitamin D in treatment and prevention.

Vitamin D intake and all-cause and cause-specific mortality in Japanese men and women: the Japan Public Health Center-based prospective study
AbstractWhile higher circulating 25-hydroxyvitamin D concentrations have been reported to be associated with decreased risk of all-cause mortality, evidence on dietary vitamin D intake is limited and inconsistent. We investigated whether vitamin D intake is associated with all-cause and cause-specific mortality among Japanese adults. Participants were 42,992 men and 50,693 women who responded to the second survey of the Japan Public Health Center-based Prospective Study (1995 –1998) and who were followed up for mortality through 2018. Dietary intake was ascertained using a validated food frequency questionnaire. Hazard r...

Associations of Plasma 25-Hydroxy Vitamin D and Dietary Vitamin D Intake with Insulin Resistance in Healthy Japanese Women
J Nutr Sci Vitaminol (Tokyo). 2023;69(1):46-52. doi: 10.3177/jnsv.69.46.ABSTRACTWe investigated the associations of plasma 25-hydroxy vitamin D (25(OH)D) concentration and the dietary intake of vitamin D with insulin resistance in Japanese women. Study participants were 406 Japanese women attended a health examination. They were not taking hormones or medications for diabetes and had no history of cancer, ischemic heart disease, or stroke. Information regarding medical history and lifestyle factors was obtained by a self-administered questionnaire, while hours of sun exposure were determined through interviews. Dietary int...
