Does a Poor Preoperative Nutritional Status Impact outcomes of Heart Valve Surgery?

Background: Malnutrition has been variously associated with poor postoperative outcomes. Of note, 10-25 % of cardiac surgery patients are reported to be malnourished.

Objectives: To assess the impact of nutritional status (evaluated with the Geriatric Nutritional Risk Index - GNRI) on outcomes of older patients undergoing heart valve surgery.

Five-Time Sit-To-Stand Lower Limb Muscle Power in Older Women: An Explorative, Descriptive and Comparative Analysis.

Background: Muscle power assessment entails the use of complex equipment which impacts its clinical applicability. Recently, equations to estimate lower-limb muscle power measures based on 5-repetition sit-to-stand (5STS) performance and anthropometric parameters were validated. However, their ability to discriminate physical performance status in older adults is still unknown.

Waist-to-calf circumference ratio as a potential indicator of diabetes risk: results from the Longevity Check-Up (Lookup) 8.

Diabetes is a prevalent metabolic condition with substantial health and economic impacts. Therefore, effective and accessible indicators are essential for early detection and prevention. This study investigates the link between the waist-to-calf circumference ratio (WCR) and diabetes risk in a large cohort from the Longevity Check-Up (Lookup) 8+ Study.

Beetroot juice intake positively influenced gut microbiota and inflammation but failed to improve functional outcomes in adults with long COVID: A pilot randomized controlled trial.

Background & Aims: Long-term effects of coronavirus disease 2019 (long COVID) develop in a substantial number of people following an acute COVID-19 episode. Red beetroot juice may have positive effects on multiple pathways involved in long COVID. The aim of this pilot study was to explore the impact of beetroot juice supplementation on physical function, gut microbiota, and systemic inflammation in adults with long COVID.

Older patients affected by COVID-19: investigating the existence of biological phenotypes.

Introduction: COVID-19 provides an opportunity to examine biological phenotypes (observable morphological, functional and biological characteristics) in individuals who experience the same acute condition, potentially revealing differences in response to acute external stressors. The aim our study was to investigate biological phenotypes in older patients hospitalized for COVID-19, exploiting a panel of aging biomarkers.

Methods: Data were gathered from the FRACOVID Project, an observational multicenter study, aimed to evaluate the impact of frailty on health-related outcomes in patients 60 + with COVID-19 in Northern Italy.

Mitochondrial quality control measures, systemic inflammation, and lower-limb muscle power in older adults: a PROMPT secondary analysis.

Objectives: The study was conducted to explore associations between markers of mitochondrial quality control (MQC) from vastus lateralis muscle biopsies, serum inflammatory markers, and measures of muscle power assessed by two different tools in a sample of older adults.

Design: Secondary analysis of data collected in the PeppeR develOpMental ProjecT (PROMPT) at the University of Florida (Gainesville, FL, USA).

Methods: Forty-three older adults (n = 20 women) were included in the study.

Mitochondria break free: Mitochondria-derived vesicles in aging and associated conditions.

Mitophagy is the intracellular recycling system that disposes damaged/inefficient mitochondria and allows biogenesis of new organelles to ensure mitochondrial quality is optimized. Dysfunctional mitophagy has been implicated in human aging and diseases. Multiple evolutionarily selected, redundant mechanisms of mitophagy have been identified, but their specific roles in human health and their potential exploitation as therapeutic targets are unclear.

Mitochondrial pathways and sarcopenia in the geroscience era.

Sarcopenia is associated with structural, ultrastructural, and molecular abnormalities of skeletal muscle. Mitochondrial dysfunction is a pivotal factor involved in muscle aging and sarcopenia. Mitochondrial bioenergetics are significantly reduced in muscles of older adults which is associated with whole-body aerobic capacity, muscle strength, and physical performance.

Emerging Targets and Treatments for Sarcopenia: A Narrative Review.

The influence of ageism on the hallmarks of aging: Where age stigma and biology collide.

Ageism encompasses the creation of negative stereotypes of aging that culminate in the development of prejudicial thoughts and discriminatory actions against people in advanced age. Stereotypes refer to major characteristics, overgeneralized, not supported by observations, that are created to categorize, simplify, and combine complex characteristics, attributes, and behaviors shared by members of a group into more simplistic categories. Negative aging stereotypes include the assumption that old people are weak, reminiscent, sick, and tired, to quote a few.

Mitochondrial Quality Control Processes at the Crossroads of Cell Death and Survival: Mechanisms and Signaling Pathways.

Biological aging results from an accumulation of damage in the face of reduced resilience. One major driver of aging is cell senescence, a state in which cells remain viable but lose their proliferative capacity, undergo metabolic alterations, and become resistant to apoptosis. This is accompanied by complex cellular changes that enable the development of a senescence-associated secretory phenotype (SASP).
