A multivariate survival model induced by discrete frailty
(Taylor & Francis Inc, 2020-08-11)
Frailty models are generally used to model heterogeneity and dependence between individuals. The distribution of the frailty variable is often assumed to be continuous. However, there are situations where a discretely-distributed ...
Frailty And Depressive Symptoms In Older Adults: Data From The Fibra Study - Unicamp
(Springer Int PublishingCham, 2016)
Current perspectives on defining and mitigating frailty in relation to critical illness
(2021-11-01)
Up to half of ICU survivors, many of whom were premorbidly well, will have residual functional and/or cognitive impairment and be vulnerable to future health problems. Frailty describes vulnerability to poor resolution of ...
Survival model induced by discrete frailty for modeling of lifetime data with long-term survivors and change-point
(Taylor & Francis Inc, 2019-07-30)
Frailty models are used for modeling heterogeneity in the data analysis of lifetimes. Analysis that ignore frailty when it is present leads to incorrect inferences. In survival analysis, the distribution of frailty is ...
Frailty modelling for clustered recurrent incidence of diarrhoea
(2008)
Recurrent incidence of infant diarrhoea is studied, using daily data collected in Salvador, Brazil, from 754 children over 455 days. Aalen's additive intensity model is taken as the basis of the modelling strategy and a ...

Bivariate survival models based on the presence of an unobseved random covariate, grailty, tend to assume a proportional hazard hypothesis. A bivariate survival model is constructed. It is based on frailty model that acts ...

Lamin A expression in circulating osteoprogenitors as a potential biomarker for frailty: The Nepean Osteoporosis and Frailty (NOF) Study
(Elsevier, 2018-02)
Lamin A is a protein of the nuclear lamina. Low levels of lamin A expression are associated with osteosarcopenia
in mice. In this study, we hypothesized that low lamin A expression is also associated with frailty in humans. ...
Analysis of the characteristics and components for the frailty syndrome in older adults from central Chile. The PIEI-ES study
(Elsevier Ireland Ltd, 2019)
Objective: To determine the prevalence and to characterize frailty in elderly subjects in four urban provincial capitals and two rural communes from Maule Region in Chile. Design: Cross-sectional study. Participants: 1205 ...
Multidimensional frailty, quality of life and self-management in aging Hispanics living with HIV
(2024)
An observational cross-sectional study was conducted to examine multidimensional frailty and its potential impact on quality of life (QOL) in aging Hispanic people living with HIV (PLWH) and assess the extent to which HIV ...
