The Role of Nutrition in the Treatment of Sarcopenia in Old Patients: From Restoration of Mitochondrial Activity to Improvement of Muscle Performance, a Systematic Review.

Sarcopenia is an age-related disease characterized by loss of muscle strength, mass and performance. Malnutrition contributes to sarcopenia pathogenesis. The aim of this systematic review is to analyze existing evidence on the efficacy of nutritional supplementation on muscle and mitochondrial health among sarcopenic or malnourished older adults.

Trends in the disability-free life expectancy in Switzerland over a 10-year period: an analysis of survey-based data.

Introduction: Increasing life expectancy raises concerns whether the years gained will be spent free of disability. Lately, trends across countries have been heterogeneous. This work examined recent trends in disability-free life expectancy and life expectancy with mild  or severe disability in Switzerland.

SARS-CoV-2 Seroprevalence in Employees of Four Essential Non-Health Care Sectors at Moderate/High Risk of Exposure to Coronavirus Infection: Data From the "First Wave".

Objective: The aim of this study was to evaluate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence in Swiss non-health care employees at a moderate to high risk of exposure: bus drivers and supermarket, laundry service, and mail-sorting center employees.

Methods: Data on 455 essential workers included demographics, SARS-CoV-2 exposure and use of protective measures. Anti-SARS-CoV-2 immunoglobulins G and A targeting the spike protein were measured between May and July 2020.

Fear of falling and all-cause mortality among young-old community-dwelling adults: a 6-year prospective study.

This study investigated whether fear of falling (FOF) measured by two different instruments, the Falls Efficacy Scale-International (FES-I) and the single question on FOF and activity restriction (SQ-FAR), is associated with mortality at 6-year follow-up. Participants ( = 1359, 58.6% women) were community-dwelling persons enrolled in the Lausanne cohort 65 + , aged 66 to 71 years at baseline.

Combined anterior segment OCT and wavefront-based autorefractor using a shared beam.

We have combined an anterior segment (AS) optical coherence tomography (OCT) system and a wavefront-based aberrometer with an approach that senses ocular wavefront aberrations using the OCT beam. Temporal interlacing of the OCT and aberrometer channels allows for OCT images and refractive error measurements to be acquired continuously and in real-time. The system measures refractive error with accuracy and precision comparable to that of clinical autorefractors.

Falls Efficacy Is Associated With Better Gait and Functional Outcomes After Rehabilitation in Older Patients.

Objective: To examine the relationship between falls efficacy and the change in gait speed and functional status in older patients undergoing postacute rehabilitation.

Design: Prospective cohort study.

Setting: Postacute rehabilitation facility.

Is Fear of Falling Associated With Incident Disability? A Prospective Analysis in Young-Old Community-Dwelling Adults.

Objectives: Fear of falling (FOF) is common in older people and is related to negative outcomes. This study aimed to investigate whether 2 different instruments, the Falls Efficacy Scale-International (FES-I) and the single question on FOF and activity restriction (SQ-FAR), were associated with incident disability at 3 years.

Design: Prospective observational study.

A Single Question as a Screening Tool to Assess Fear of Falling in Young-Old Community-Dwelling Persons.

Objectives: Fear of falling (FOF) is common in older persons and related to negative outcomes. This study aimed to investigate the relationship between 2 FOF measures: the Falls Efficacy Scale-International (FES-I) and the single question on FOF and activity restriction (SQ-FAR). Factors associated with disagreement between the 2 measures were further examined.

Frailty and Intrinsic Capacity: Two Distinct but Related Constructs.

Frailty is a clinical condition characterized by the individual's increased vulnerability to endogenous and exogenous stressors. It is determined by the reduction of homeostatic capacities of the organism and responsible for a marked risk of adverse health outcomes (including functional loss and mortality). Frailty originates from the geriatric background and may pave the way toward a model of care centered on the person, deviating from the traditional and obsolete disease-focused approach.

The Mirror Neurons Network in Aging, Mild Cognitive Impairment, and Alzheimer Disease: A functional MRI Study.

The aim of the current study is to investigate the integrity of the Mirror Neurons (MN) network in normal aging, Mild Cognitive Impairment (MCI), and Alzheimer disease (AD). Although AD and MCI are considered "cognitive" diseases, there has been increasing recognition of a link between motor function and AD. More recently the embodied cognition hypothesis has also been developed: it postulates that a part of cognition results from the coupling between action and perception representations.
