A Full-Scale Agent-Based Model to Hypothetically Explore the Impact of Lockdown, Social Distancing, and Vaccination During the COVID-19 Pandemic in L…

2021

Background The COVID-19 outbreak, an event of global concern, has provided scientists the opportunity to use mathematical modeling to run simulations and test theories about the pandemic. Objective The aim of this study was to propose a full-scale individual-based model of the COVID-19 outbreak in Lombardy, Italy, to test various scenarios pertaining to the pandemic and achieve novel performance metrics. Methods The model was designed to simulate all 10 million inhabitants of Lombardy person by person via a simple agent-based approach using a commercial computer. In order to obtain performance data, a collision detection model was developed to enable cluster nodes in small cells that can b…

Mortality attributable to COVID-19 in nursing home residents: a retrospective study

2021

AbstractAimCoronavirus-19 disease (COVID-19) is a widespread condition in nursing home (NH). It is not known whether COVID-19 is associated with a higher risk of death than residents without COVID-19. Therefore, the aim of this study was to assess whether COVID-19 is associated with a higher mortality rate in NH residents, considering frailty status assessed with the Multidimensional Prognostic Index (MPI).MethodsIn this retrospective study, made in 31 NHs in Venice, Italy, the presence of COVID-19 was ascertained with a nasopharyngeal swab. Frailty was evaluated using the MPI, modified according to the tools commonly used in our NHs. A Cox’s regression analysis was used reporting the resul…

Physical Multimorbidity and Sarcopenia among Adults Aged ≥65 Years in Low- and Middle-Income Countries.

2022

<b><i>Introduction:</i></b> Physical multimorbidity is plausibly linked to sarcopenia. However, to date, only a few studies exist on this topic, and none have examined this association in low- and middle-income countries (LMICs). Thus, we aimed to investigate the association between multimorbidity and sarcopenia in a sample of older adults from six LMICs (China, Ghana, India, Mexico, Russia, South Africa). <b><i>Methods:</i></b> Cross-sectional, community-based data from the WHO Study on Global Ageing and Adult Health (SAGE) were analysed. Sarcopenia was defined as having low skeletal muscle mass (SMM) and weak handgrip strength, while severe …

Association of frailty with fall events in older adults: A 12-year longitudinal study in Korea

2022

Background: Evidence has shown that frailty is associated with the risk of falls in older people. However, the components of frailty that have the highest association with fall events are largely unknown. Methods: This study analyzed panel data from the Korean Longitudinal Study of Aging. We used the Korean Frailty Instrument, which includes domains for social isolation, exhaustion and weakness estimated by grip strength, to assess frailty. Fall event data were collected during follow-up visits. Results: A total of 3122 community-dwelling adults aged 65 years or older were included at baseline in 2006 and were followed up every 2 years until 2018. The participants with frailty had a higher …

Anti-Aging Effects of GDF11 on Skin

2020

International audience; Human skin is composed of three layers: the epidermis, the dermis, and the hypodermis. The epidermis has four major cell layers made up of keratinocytes in varying stages of progressive differentiation. Skin aging is a multi-factorial process that affects every phase of its biology and function. The expression profiles of inflammation-related genes analyzed in resident immune cells demonstrated that these cells have a strong ability to regenerate adult skin stem cells and to produce endogenous substances such as growth differentiation factor 11 (GDF11). GDF11 appears to be the key to progenitor proliferation and/or differentiation. The preservation of youthful phenot…

Development and validation of prediction model to estimate 10-year risk of all-cause mortality using modern statistical learning methods: a large pop…

2021

Abstract Background In increasingly ageing populations, there is an emergent need to develop a robust prediction model for estimating an individual absolute risk for all-cause mortality, so that relevant assessments and interventions can be targeted appropriately. The objective of the study was to derive, evaluate and validate (internally and externally) a risk prediction model allowing rapid estimations of an absolute risk of all-cause mortality in the following 10 years. Methods For the model development, data came from English Longitudinal Study of Ageing study, which comprised 9154 population-representative individuals aged 50–75 years, 1240 (13.5%) of whom died during the 10-year follo…

Macular pigment change during eye ageing : analysis from population based study, Montrachet study

2018

Given the limits of the literature on the environmental nutritional impact in ocular aging witch is partially due to the lack of data in general population notably in French elderly, first, we were interested in the relationships of diet, plasma xanthophylls and macular pigment optical density as well as its spatial distribution and second of plasma fatty acids and dry eye disease signs in the 1153 Montrachet study participants.Firstly, we reported the high consumption of squash, the high plasma lutein and zeaxanthin levels and also the high plasma lutein level, the high macular pigment optical density level in nonsmokers subjects. In addition, the macular pigment values we provided in the …
