BACKGROUND the link between the vitamin D endocrine axis and frailty remains undefined, with few studies examining the joint effect of vitamin D and parathyroid hormone (PTH) levels. Our objective was to determine the association of frailty with serum 25-hydroxyvitamin D (25(OH)D) and PTH. SETTING cross-sectional analysis within the European Male Ageing Study (EMAS). PARTICIPANTS a total of...
BACKGROUND- Although older patients frequently undergo percutaneous coronary interventions (PCI), frailty, comorbidity, and quality of life are seldom part of risk prediction approaches. We assessed their incremental prognostic value over and above the risk factors in the Mayo Clinic risk score. METHODS AND RESULTS- Patients ≥65 years who underwent PCI were assessed for frailty (Fried criteria)...
We present a Bayesian analysis for recurrent events data using a nonhomogeneous mixed Poisson point process with a dynamic subject-specific frailty function and a dynamic baseline intensity function. The dynamic subject-specific frailty employs a dynamic piecewise constant function with a known pre-specified grid and the baseline intensity uses an unknown grid for the piecewise constant functio...
This paper reviews some of the main approaches to the analysis of multivariate censored survival data. Such data typically have correlated failure times. The correlation can be a consequence of the observational design, for example with clustered sampling and matching, or it can be a focus of interest as in genetic studies, longitudinal studies of recurrent events and other studies involving mu...
BACKGROUND Age-associated brain physiologic decline and reduced mobility are key elements of increased age-associated vulnerability. OBJECTIVE To study the frequency of frailty phenotype and its association with mental health and survival in older Chileans. METHODS Follow-up of ALEXANDROS cohorts designed to study disability associated with obesity in community-dwelling people 60 years and ...
SUMMARY Preoperative frailty predicts adverse postoperative outcomes. Recommendations for preoperative assessment of elderly patients include performing a frailty assessment. Despite the advantages of incorporating frailty assessment into surgical settings, there is limited research on surgical health care professionals' perception and use of frailty assessment for perioperative care. We survey...
