Filter by:This research will test the hypothesis that immune system disequilibrium / dysfunction explains why preoperative cognitive impairment is a strong predictor of postoperative morbidity in older surgical patients. The investigators propose that cognitive impairment influences surgical morbidity because of underlying immune disequilibrium / dysfunction (risk marker) and that this shapes the immune response to surgery and defines immunological hallmarks of postoperative morbidity (disease marker). The overarching goal of this application therefore is to define and better understand the clinical immunology underlying the relationship between cognition and geriatric surgical morbidity.
Ageing is associated with the development of various negative conditions, such as frailty. Defined as a decreased ability to combat negative stressors (e.g. injury and illness), frailty is highly prevalent in elderly adults and significantly increases an individual's risk of adverse events such as falls, illness and death. The underlying physical characteristics of frailty are currently incompletely understood, with many previous studies focusing on one tissue (e.g. the brain) in isolation. However, frailty is known to affect many tissues simultaneously, and to further our insight into the biological basis of frailty and how to treat it, we must determine how different organs are affected at the same time. The study will look at the physical characteristics of non-frail and frail elderly females (aged 65 years and over), who are attending geriatric clinics across the Nottingham University Hospitals NHS Trust. We will aim to recruit 51 participants with this cohort broken down into non-frail (n=17), pre-frail (n=17) and frail (n=17) subgroups. Participants will be allocated to these groups based on their Electronic Frailty Index, Clinical Frailty Scale and Fried frailty phenotype scores. All participants will undergo basic muscle function tests (grip strength, leg strength and muscle activity) and questionnaires on their first visit to University of Nottingham laboratories. At a second visit, they will then undergo one Magnetic Resonance Imaging (MRI) scanning session, at the Sir Peter Mansfield Imaging Centre within the University, to gather information about the structure and function of their heart, brain and skeletal muscle. MRI scan protocols will take approximately 45-60 mins. Data gathered from MRI scanning will be compared across non-frail, pre-frail and frail groups to investigate differences across frailty states, with the aim of highlighting the defining physical characteristics of the frail state which may help to develop future treatment interventions to combat the condition. We hypothesise that frail females will present with common physical characteristics, the clustering of which will be indicative of frailty severity. We also hypothesise that certain physical traits present in the frail will not be present in the non-frail.
The POSITIVE platform offers the possibility of unsupervised monitoring of pre-frailty and frailty status in a community setting, to detect the onset of frailty and to assess its evolution. The primary objective of the study is to evaluate whether the POSITIVE system improves frailty in at least 1 point in the Fried's Criteria and 5 points in the FTS-5. This is a multi-centre, non-inferiority, randomized, simple blind and prospective pilot study with a 12-month follow up duration. The study will be carried out in Spain, Sweden and Poland. 150 participants will be randomized into two groups. The control group will receive usual medical care. The intervention group will receive, in addition, the POSITIVE frailty home monitoring and intervention system.
This is a prospective observational clinical trail which will recruit 1000-1500 participants over 65 years with frailty and acute coronary syndrome (ACS) in Beijing Friendship hospital. The investigators will conduct frailty assessment (FRAIL scale, CFS, SPPB), comorbidities, functional status (Barthel index, ADL, IADL), nutritional risk (MNA-SF), and then observe the clinical outcomes of elderly ACS participants with frailty. Then, the investigators will follow-up these participants separately in 1,3,6 and 12months, the anticipate follow-up time is 1 year. According to the follow-up results, investigators will evaluate the impact of frailty and other senile syndromes on the short-term and long-term prognosis of ACS, and develop a scoring system for the prognosis evaluation of elderly ACS participants.
Aging represents a huge advance in society and a health and social challenge. Spain has one of the highest life expectancies in the world, but other countries with the same demographic characteristics are ahead of us in quality adjusted life years. Primary care setting has the main drivers of healthy aging, acting on the early stages of pre-frailty and frailty. Therefore, it is proposed a multicomponent intervention (nutritional and prescription of physical exercise) in patients older than 70 years of the Medina del Campo Health Center, with pre-frailty criteria, in order to measure the changes that this intervention produces in their mild dysfunction and whether it is capable of reversing it or delaying the progression to a state of frailty.
Frailty syndrome (i.e. frailty) is a geriatric syndrome which relies on the reduction of multisystem reserve capacity. Frail people have a lower potential to respond to external stressors and various life incidents as well as they present a weak prognosis particularly in cardiovascular diseases. Yet, frailty is not only a set of physical deficits, but it also concerns psychological and social dimensions of human functioning. Hence, an approach to frailty should be multidimensional because such a concept more adequately reflects a functional degradation in the elderly. Frailty is usually associated with the impaired condition of circulatory system, and therefore, an identification of subclinical cardiovascular abnormalities is paramount in the frailty prevention and treatment. Another potential mechanism which may predispose to frailty is a dysfunction of the autonomic nervous system. This system plays a crucial role in the response to internal or external stressors such as diseases and activities of daily living. An impairment of the autonomic nervous system function may maintain or accelerate the frailty process. In this scientific project, a comprehensive echocardiography will investigate cardiac function with a particular attention to features which typically change with age, like flow parameters and chambers sizes. The activity of the autonomic nervous system will be explored with the analysis of heart rate, blood pressure and respiratory signals. The study participants will also undergo routine medical examination and a number of additional tests, including: assessment of cognitive function, psychological condition, nutrition status, activities of daily living, and risk of falls. The study group will comprise community dwelling elderly individuals over the age of 65 years who get around by themselves. After 2 years, the participants will be re-examined for their frailty and independence status, as well as their survival will be checked with the National Health Found electronic system. The aim of this project is to seek for factors determining frailty and to explore the frailty impact on the elderly people survival. Particular attention will be paid to the multidimensional frailty which is a new concept of the functional decline in the elderly. In addition, the prevalence of different modes of frailty in Polish community will be investigated. The results of this research should help to establish preventative and therapeutic strategies against frailty.
This multicentric, randomised controlled trial is to the investigators knowledge the first implementation of a multimodal, multidisciplinary prehabilitation approach using knowledge from different specialties to lower complications and to increase cost effectiveness after major surgery in elderly, frail patients.
In this pilot study, we will investigate whether - with the current dosing regimens, used in the Ghent University Hospital - pharmacodynamic targets regarding beta-lactam antibiotics (more specific Amoxicilline-Clavulanate, Piperacillin-Tazobactam and Temocillin) are attained in frail patients admitted to the geriatric department.
Frailty is a multideterminant syndrome in which muscle function appears to play a central role. Muscle function depends on brain control, nutrition and perfusion. We hypothesized that multiparametric MRI assessment combined with comprehensive gerontological assessment (CGA) and routine biological assessment of inflammation in a sample of older people with and without diabetes will allow to explore on one side the possibilities of multi-parametric MRI muscle and brain imaging to describe the correlates of frailty and on the other side will describe the different muscle/brain alterations due to diabetes in frailty. The main objective is to compare the lipid percent of the rectus femoris in frail and pre-frail older subjects and in non-frail older subjects.
In the context of reduced resources and rising demand for unplanned care, the delivery of appropriate services to support people with frailty will be key to providing cost-effective, quality care for older people. There is recognition of an evidence gap in relation to the planning, commissioning and delivery of services for older people living with frailty. Questions remain about the incidence and prevalence different levels of frailty and the consequences for health outcomes, health and care service use and costs. In this study, the investigators will explore the incidence and prevalence, development and impact of frailty within the population using retrospective primary care data on patients aged 50 and over in 2006 within the database. The investigators will stratify the cohort by severity of frailty and explore frailty status over time, determining incidence, prevalence and progression of frailty. The relationships between factors such as age, deprivation, ethnicity, location and comorbidities of individuals in relation to development of, and deterioration in, frailty status will be examined. The influence of frailty on outcomes, service use and costs will be explored. These analyses will be used to inform the development of a prototype simulation model, which will use a System Dynamics (SD) based approach to explore the development and impact of frailty in the population and likely future scenarios over a 10-year timeframe. Finally, 'what if' scenarios developed with the stakeholder engagement group will be explored via simulation modelling.
