Active clinical trials for "Frailty"

To study whether there is a correlation between weakness and postoperative delusions in elderly non-cardiac surgery patients Can the improved debilitating index predict the delusion after non-cardiac surgery Which of the debilitating index are independent risk factors associated with postoperative delusions

The goal of this study is to investigate the influence of frailty on clinical and stroke characteristics, treatment and outcomes in patients with acute stroke. The main questions it aims to answer are: How prevalent is frailty in patients with stroke? Which impairments (e.g. undernutrion, impaired mobility, laboratory markers) contribute to frailty? Is the outcome of frail patients worse than those without? Are in-hospital complications more frequent in frail patients than those without?

Frailty has been proposed as a measure of biological (as opposed to chronological) aging. In this study the investigators plan to: (1) measure frailty in a cohort of older HIV-infected individuals in Hong Kong, and its association with mortality and quality of life; (2) identify risk factors predictive of development of frailty in HIV-infected individuals in Hong Kong; and (3) determine the outcomes of HIV-infected individuals in Hong Kong with and without frailty. The following assessment will be done: Physical examination including measuring height, weight, hip and waist circumference. Grip strength, chair stand test, gait speed test, balance tests, and neurocognitive tests Geriatric syndromes, screening for depression, disability and quality of life. Blood tests during fasting state to measure metabolic parameters. This is a prospective longitudinal observational study that lasts for 10 years.

Frailty, a transitional state between successful and pathological aging, may be benefit from early multi-interventional intervention. Fried's criteria are the more commonly used criteria to diagnose frailty. The caregivers' burden increases caregivers' morbidity .The main objective of the study was to assess the relationship between frailty among informal caregivers of demented patients and the caregiver's burden (Zarit scale). The Secondary objective was to assess determinants of frailty among caregivers.

The investigators seek to construct a novel, multimodal, distributed system that facilitates a new paradigm of home-based medical surveillance and treatment for frail older adults centered on timely diagnosis of movement system impairments and personalized intervention. Measurements from a heterogeneous set of complementary sensors will be combined with clinically-informed and data-learned dynamic models of human motion to enable real-time activity recognition (e.g., sitting, standing, walking) and movement assessments (e.g., speed, repetition, quality). As the study progresses, the system will be integrated with wearable assistive technology to provide "smart", activity-specific assistance of movement deficits or the activation of caregivers if a decline in function is detected. Finally, the investigators will test the combined assessment and intervention system in the clinic and the home, identifying challenges and solutions for the scaling up to unconstrained real-world settings.

The investigators plan to measure the changes of health-related quality of life (HRQoL) at 6 months and 12 months after the following high-risk oncological abdominal surgery: gastrectomy, esophagectomy, pancreatectomy and hepatectomy. The investigators will measure the HRQoL using the validated EORTC QLQ-C30 questionnaire before and at 6 months and 12 month after the surgery. The investigators will identify phenotypes of HRQoL changes (improvement, stability and deterioration) at 6 months and 12 months after surgery. The second aim is to assess the regret of the patient at 6 months and 12 months regarding his/her decision to undergo surgery. The investigators will also assess the regret of the next of kin at 6 months regarding the decision to undergo surgery. This descriptive, prospective, observational, single-centre cohort study aims to: identify phenotypes of HRQoL changes after abdominal surgical oncology (improvement, stability and deterioration); assess the regret of patients regarding their decision to undergo surgical oncology at 6 months and 12 months; assess the regret of the next of kin regarding the decision of the patient to undergo surgical oncology at 6 months and 12 months. The investigators will include patients scheduled for the following elective abdominal cancer surgery: gastrectomy; esophagectomy; pancreas resection and hepatectomy. The investigators will assess HRQoL using the validated EORTC QLQ-C30 Summary Score before and 6 months and 12 months after surgery. The cut-offs for the three phenotypes of HRQoL changes will be defined using the minimal clinically important difference (MCID) of 10 points. The investigators will assess regret using the Decision Regret Scale (DRS) at 6 months and 12 months after surgery. The expected results are: The investigators can identify phenotypes of HRQoL changes after surgical oncology using the EORTC QLQ-C30 Summary Score; the investigators will describe the distribution of these phenotypes and will find an association with the pre-existing frailty. The investigators can describe the extent of the regret of the patient and of the next of kin at 6 months using the DRS. The investigators will observe an association between the DRS score at 6 months and the HRQoL Summary Score change. The investigators will not observe a relationship between the DRS score of patients and next-of-kins.

Single-centre prospective cohort study of patients presenting with severe limb ischaemia (SLI). The primary outcome measure will be 12 month major amputation rate. A historical cohort of patients identified retrospectively will be the comparitor group used to assess the impact of a newly-established rapid-access limb salvage clinic. Primary aim: - Determine the proportion of patients with SLI undergoing major lower limb amputation within 12 months of presentation. Secondary aims: Assess clinically important short-, medium- and long-term outcomes in those undergoing and not undergoing amputation Prevalence and degree of frailty and cognitive impairment Pevalence and degree of cardiac disease (detected by stress MRI) Establish a biobank for future biomarker analysis Investigate the role of frailty and cognitive assessments, cardiac MRI and biomarkers in risk-stratification of patients with SLI

There are few studies that already have validated specific raw accelerometer cut-points for people over 65 years old. The purpose of the present study is to validate raw accelerometer cut points for general people over 65 years old and specific raw accelerometer cut points based on the functional status of older adults over 65 years old. The study will be carried out with an observational approach. Participants will be divided into 4 groups. First of them will be made grouping all subjects and the rest divided according to their functional status. They will perform different-intensity physical activities while wearing accelerometers attached to their body and wearing a portable gas analyser too. Their intensity will be assessed based on their own Rest Metabolic Rate (RMR). Energy expenditure and accelerations will be matched and, based on that, sedentary behaviour, light physical activity and moderate-to-vigorous physical activity cut-points will be derived.

Evaluate the sensitivity of the GERONTOPOLE scale, used by general practitioners in primary care outpatients for the diagnosis of frailty in non-dependent people more than 65 years old, using as reference the "évaluation gériatrique standardisée clinique" (EGS)
