Chronic systematic inflammation and reduced immune system fitness are considered potential contributing factors to the development of age-related frailty, but the underlying mechanisms are poorly defined. This exploratory study aimed to identify frailty-related inflammatory markers and immunological phenotypes in a cohort of community-dwelling adults aged ≥ 55 years. Frailty was assessed using ...

Urinary incontinence (UI) is very common in the elderly and has personal and social implications. Many authors have pointed out the necessity to analyze UI in correlation with the overall quality of aging, to better understand this syndrome and define measures for its prevention and treatment. In the present study, we addressed this problem by analyzing the UI correlation with frailty, which ha...

Due to natural or artificial clustering, multivariate survival data often arise in biomedical studies, for example, a dental study involving multiple teeth from each subject. A certain proportion of subjects in the population who are not expected to experience the event of interest are considered to be "cured" or insusceptible. To model correlated or clustered failure time data incorporating a ...

BACKGROUND on an individual level, lower-income has been associated with disability, morbidity and death. On a population level, the relationship of economic indicators with health is unclear. OBJECTIVE the purpose of this study was to evaluate relative fitness and frailty in relation to national income and healthcare spending, and their relationship with mortality. DESIGN AND SETTING secon...

We assessed the frailty status of inpatients and analyzed the factors influencing frailty status to explore the reasons for frailty and identify feasible intervention strategies.A total of 1494 geriatric patients aged ≥60 years were recruited as subjects. All patients were hospitalized between September 2014 and August 2015 in the internal medicine units of 3 hospitals in Chongqing and Zunyi in...

Frailty is a geriatric syndrome associated with adiposity. Zinc alpha2-glycoprotein (ZAG), a novel adipokine, is a modulator of body fat mass and positively correlates with age. This observational study aims to investigate the relationship between plasma ZAG levels and frailty in the elderly.We enrolled 189 elder participants from a hospital-based comprehensive geriatric assessment program in T...

INTRODUCTION Frailty is associated with a functional decline of multiple physiological systems, of which they may be a cause or consequence. The objective of the study was to evaluate the prevalence of thyroid hormone modifications in elderly frail subjects and its relationship with frailty. STUDY POPULATION AND METHODS An observational study was carried out at the University Hospital "Tor Ve...

The joineR package implements methods for analysing data from longitudinal studies in which the response from each subject consists of a time-sequence of repeated measurements and a possibly censored time-toevent outcome. The modelling framework for the repeated measurements is the linear model with random effects and/or correlated error structure. The model for the time-to-event outcome is a C...

1 Summary In this work we provide a simple estimation procedure for a general frailty model for analysis of prospective correlated failure times. Rigorous large-sample theory for the proposed estimators of both the regression coefficient vector and the dependence parameter is given, including consistent variance estimators. In a simulation study under the widely used gamma frailty model, our pr...
