The Impact of Geriatric Assessment on the Treatment Plan of Elderly Patients With T2DM

Introduction: With the aging of the world population and the increasing incidence of type 2 diabetes mellitus (T2DM) with age, the number of elderly individuals living with diabetes has been considerably rising. It is known that uncontrolled T2DM negatively impacts various health outcomes, including geriatric outcomes such as sarcopenia, frailty, immobility, incontinence, and infections. Current medical literature fails to establish appropriate glycemic targets for different elderly profiles. Although guidelines emphasize the need to individualize targets, there is no concise tool to identify which individuals benefit from each therapeutic approach. Data suggest that frailty is the best predictor of negative outcomes in elderly patients living with T2DM. The Clinical Frailty Scale (CFS) and the 10-minute Targeted Geriatric Assessment (TaGA-10) are validated tools for prognosis in elderly patients and for identifying frail elderly individuals. Methods: Randomized controlled trial. Elderly individuals diagnosed with T2DM at a tertiary care outpatient clinic will be included. All enrolled patients will undergo geriatric assessment using CFS, TaGA-10, and Charlson Comorbidity Index. Patients will be randomized into usual care and intervention groups, and the intervention involves providing the geriatric assessment to the care team to support their decisions. The adequacy of the therapeutic approach will be measured in one week by reviewing the consult record or interviewing the physician. The clinical impact on the frequency of hypoglycemia, falls, infections, hospitalizations, and mortality will be evaluated at 3 and 6 months by telephone interviews. Discussion: Current guidelines recommend using age, comorbidities, cognitive, and functional status to individualize therapeutic targets in elderly patients with T2DM; however, it is possible that these variables alone may not be sufficient to classify all elderly individuals in their complexity adequately. A tool with such power and easy to use in clinical practice is necessary.

Targeted Prehabilitation With Physical Exercise and Inspiratory Muscle Training for Elderly Frail Patients Prior to Ventral Hernia Repair

The purpose of this study is to assess the physical fitness of patients undergoing hernia repair and correlate the postoperative outcomes and recovery as well as assess the impact of a targeted physical exercise program preoperatively in a cohort of frail, elderly patients. The investigators hypothesize that physical exercise will improve activity levels in elderly patients with frailty prior to ventral hernia repair. The investigators further hypothesize that increased levels of activity preoperatively will correlate with improved postoperative outcomes.

EVOLUTION IN FRAGILITY IN PEOPLE ON THE WAITING LIST FOR A KIDNEY TRANSPLANT

This study looks at how the physical and emotional health of people changes while they wait for a kidney transplant. Waiting for an organ can take a long time. During this period, some patients become "frail." This means they lose strength and are at a higher risk for health problems. The main goal is to follow these patients over time to better understand their needs. Researchers will use a mobile app to collect information directly from patients about how they feel and their quality of life. The study will also include personal interviews to learn about the patients' experiences and any difficulties they face when using technology. The results of this study will help to: * Identify early which patients are losing strength or health. * Improve the support that nurses provide during the transplant waiting period. * Make sure that digital health tools are easy for everyone to use. In short, this work aims to help patients reach the day of their surgery in the best possible condition.

Evaluation of Frail Elderly in Ambulatory Primary Care

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)

Preoperative Oral Nutrition And Outcomes In Frail Elderly Patients With Femur Fractures

The goal of this observational study is to learn whether preoperative oral nutrition support improves clinical outcomes in elderly patients with femur fractures who have a high frailty index. The main questions it aims to answer are: * Does preoperative nutrition support improve hemodynamic stability during and after surgery? * Does it reduce postoperative complications, mortality, and length of hospital stay? Researchers will compare patients who receive preoperative oral nutrition support with those who follow routine nutrition. Participants will: * Receive routine medical care with or without nutrition support * Have their hemodynamic values, complications, and outcomes recorded during hospitalization * Be followed at 30 and 90 days after surgery for complications and mortality.

Investigating the Combined Effects of Protein, Blueberries, and Exercise on Cardiovascular Health and Frailty in Older Nova Scotians

Cardiovascular diseases (CVD) are a leading cause of morbidity and mortality worldwide. While CVDs are predominantly diseases of aging, age itself does not predict CVD risk; people age at different rates. Frailty is a state of accelerated aging that increases the risk of adverse health outcomes. Frail people are at higher risk of developing CVDs, experiencing complications, and dying from these diseases than fit people of the same age. Indeed, frailty predicts the likelihood of developing CVD independently of traditional risk factors for CVD. It is known that older women are frailer than men and tend to express CVDs differently than men, but whether relationships between frailty and CVD are sex specific is unclear. It is possible that shared pathophysiological mechanisms such as chronic inflammation may help explain links between CVD and frailty. Importantly, the degree of frailty can be modified by lifestyle interventions. For example, sedentary lifestyles, food insecurity, and suboptimal dietary habits can exacerbate frailty whereas diet and exercise interventions can attenuate frailty. The investigators propose that a comprehensive health strategy targeting diet and physical activity to reduce frailty will reduce the risk of cardiovascular disease (CVD), thereby promoting healthy aging. Engaging in physical activity (e.g. exercise) helps improve aerobic fitness, increase muscle mass, promote cardiac regeneration, enhance metabolic function, regulate blood pressure, improve insulin sensitivity, reduce inflammation (a key frailty mechanism), and lessen frailty. High-quality dietary protein is essential to maintain muscle mass/function, preserve mobility, attenuate inflammation, and reduce frailty. Packed with antioxidants such as anthocyanins and flavonoids, with high levels of fiber, vitamins, and minerals, blueberries, a local Nova Scotian food, can help lower blood pressure, improve blood vessel function, reduce inflammation, and help the body utilize dietary protein. These are critical aspects of a strong heart and healthy aging. To date, many frailty intervention studies have been limited by small sample sizes, underrepresentation of women, and/or by testing individual lifestyle modifications rather than synergistic effects; additionally, none have investigated how reducing frailty impacts cardiovascular outcomes. Our goal is to determine if a year-long multidomain intervention of protein, blueberries, and exercise reduces frailty and cardiovascular disease risk in older at-risk Nova Scotians of both sexes.

Voice-Activated Technology to Improve Mobility in Multimorbid, Frail, Homebound Older Adults (EngAGE)

The purpose of this study is to test the efficacy of EngAGE (an interactive, voice-activated app) vs usual care on improving older adult physical and social function.

Tesamorelin as an Adjunct to Exercise for Improving Physical Function in HIV

People with HIV experience earlier impairments in physical function compared to people in the general population. They also exhibit an earlier presentation and more rapid development of frailty, a multisystemic syndrome of aging characterized by reduced activity, fatigue, slowness, weakness, and weight loss. While exercise can improve physical function in people with HIV, it is less effective in doing so than in the general population and is difficult to sustain in the long-term. The goal of this clinical trial is to learn whether the medication tesamorelin will improve physical function and muscle health in adults with HIV when combined with exercise. Tesamorelin is a growth hormone-releasing hormone analogue that is FDA-approved to treat abdominal fat accumulation in people with HIV. While tesamorelin has also been shown to increase muscle mass and improve measures of muscle health, its effects on physical performance and muscle strength have not yet been evaluated. During a 24-week intervention phase, half of participants will be randomly assigned to receive tesamorelin and half of participants will be randomly assigned to receive placebo (a look-alike substance that contains no drug). All participants also will engage in a home-based exercise intervention supervised by an exercise coach. During a subsequent 24-week extension phase, individuals will be monitored off study drug and supervised exercise, and be encouraged to continue to exercise independently. The investigators will investigate effects of tesamorelin on physical function, muscle mass and quality, quality of life, and exercise adherence and self-efficacy. They also will evaluate whether effects of tesamorelin are maintained following treatment cessation. This study may identify an important strategy to improve how individuals aging with HIV function and feel with potential applications to other patient populations.

Improving Physical Ability and Cellular Senescence Elimination in HIV

This clinical trial is a Phase II study designed to test the safety and effectiveness of a combination of dasatinib and quercetin (D+Q) in improving physical function for people with HIV who are frail or prefrail. The study will involve 80 participants, all aged 50 or older, who have been living with HIV for at least 10 years determined to meet criteria for diagnosis of frail or prefrail and are currently on a stable antiretroviral therapy with viral suppression. Participants will be randomly assigned to one of two groups: one group will receive the D+Q treatment, and the other will receive a placebo. The treatment will be given in six cycles over 12 weeks, with participants taking the medication for two days followed by 12 days without treatment. After the 12-week treatment period, participants will be monitored for another 12 weeks to assess the long-term effects. The study aims to determine if D+Q can improve physical function and other health outcomes in this population. Randomization will be stratified by sex and age to ensure balanced groups.

Home-based Interventions for FrAilty preveNTion in AdultS With DIabeTes and Chronic Kidney Disease

One of the most common problems in people with diabetes (DM) and chronic kidney disease (CKD) is the high frequency of other coinciding medical conditions such as osteoporosis and frailty. Frailty in particular is very common in adults with DM and CKD and it can result in significant muscle weakness which can result in increasing difficulties with performing activities of daily life (ADL). This can lead to an increase risk for falls, bone fractures and increasing hospitalization. The investigators have showed that adults with DM and CKD who have frailty use hospital services more frequently, have reduced quality of life and difficulties with performing their ADLs1. There is some evidence that early screening for frailty and lifestyle interventions that focus on healthier eating and physical activity can help prevent frailty from getting worse. The study purpose is to develop and test a home-based lifestyle intervention program focused on optimizing diet and the ability to perform your ADLs in adults with DM and CKD. The goal of this program is to ensure that adults with DM can live healthier lives within the community.

Effects of Physical Exercise on Frailty, Mental and Physical Health of Older Adults in Rural Areas.

Global aging is a significant challenge, both economically and in terms of public health. One of the main challenges is to maintain the health and functionality of older adults. Physical exercise has been suggested as one of the best non-pharmacological tools to prevent health and functionality loss. However, existing scientific literature has mainly focused on older adults from urban centers. There are no studies focused on older people in rural areas, who have particular characteristics. The present project aims to evaluate the effects of a face-to-face and video-assisted intervention, which incorporates multi-component physical exercise with different motivational strategies, on the mental health, physical function, and frailty of individuals over 65 years of age residing in rural areas. Additionally, it aims to determine the effectiveness, safety, and adherence of new technologies in carrying out an intervention that includes multi-component physical exercise, cognitive work, and motivational strategies through video assistance for older women and men living in rural areas. A randomized controlled trial will be conducted, involving 240 people over the age of 65 who will be randomly divided into two groups. One group, the intervention group, will participate in a face-to-face multicomponent physical exercise program three times a week for 60 minutes per session over 12 weeks. After that, the intervention will continue through video-assisted sessions for the remaining nine months, divided into three blocks of two months of rest and one video-assisted intervention. The control group will continue with their usual daily activities but receive recommendations for physical activity and mental and physical health talks. Both groups will undergo a battery of tests to evaluate the effects of the interventions. The primary variable measured will be functional capacity, assessed through the Short Physical Performance Battery. Secondary variables will include health-related physical condition (Power frail app), cognitive function (Trail making test), and quality of life, among others. The results expected from this study will be of significant scientific and technical importance in the field of psycho-socio-health. Consequently, the project is of utmost importance, not only to enhance the health of the rural population but also to promote individual and social sustainability.

Effect of Sarcopenia and Frailty on Rocuronium Pharmacodynamics in Geriatric Patients

This prospective observational study aims to evaluate whether sarcopenia and frailty affect the pharmacodynamic profile of rocuronium in geriatric patients undergoing elective surgery under general anesthesia.

The Impact of a Home-Based Walking Exercise Program on Heart Failure

Heart disease is the second leading cause of death in Taiwan, with approximately 700,000 individuals affected by heart failure. Despite the proven benefits of rehabilitative exercise, participation in cardiac rehabilitation remains suboptimal. To address this, integrating physical activity into daily life, such as home-based walking exercises, offers a practical alternative to promote health and improve outcomes in heart failure patients. Walking exercises have been shown to significantly impact mortality rates and enhance the quality of life in this population. This study aims to assess the effects of a 12-week home-based walking exercise program on depression, frailty, and quality of life in patients with heart failure. Using an experimental design, heart failure patients hospitalized in a medical center's internal medicine ward were randomly divided into an experimental group (n=34) and a control group (n=34). While both groups received standard health education, the experimental group also participated in a home-based walking intervention after discharge. Data were collected before the intervention and at the 1st and 3rd months post-intervention. The generalized estimation equation (GEE) was employed to analyze changes in depression, frailty, and quality of life, focusing on group differences and interactions between time and group. The expected outcomes of the study include improved quality of life, reduced frailty, and alleviated depression in the experimental group, highlighting the value of home-based walking exercise. Additionally, the intervention model can complement existing post-discharge nursing practices by incorporating remote nursing guidance to enhance exercise adherence without increasing healthcare costs. This approach not only benefits patients by encouraging long-term physical activity but also reduces the burden on healthcare systems, making it a sustainable and effective strategy for managing heart failure.

CALLY Index, Frailty and SOFA-2 for Mortality Prediction in Geriatric ICU Patients

This study aims to evaluate the prognostic value of the C-reactive protein-albumin-lymphocyte (CALLY) index, Clinical Frailty Scale (CFS), and SOFA-2 score in predicting mortality among geriatric intensive care unit (ICU) patients. The primary outcome is ICU mortality. Secondary outcomes include 28-day mortality, ICU length of stay, duration of mechanical ventilation, need for renal replacement therapy, and vasopressor requirement. The study also investigates whether the combined use of these parameters improves predictive performance compared to conventional scoring systems such as APACHE II.

EWSs and 28-Day Mortality in Geriatric ED Patients

This prospective observational cohort study evaluated the prognostic performance of commonly used early warning scores for predicting 28-day all-cause mortality among geriatric patients presenting to the emergency department with non-traumatic conditions. Patients aged 65 years and older were consecutively screened during the study period. Demographic characteristics, comorbidities, vital signs, level of consciousness, blood gas parameters, complete blood count parameters, frailty status, and early warning scores were recorded at emergency department presentation or within the first hour of admission. The evaluated scoring systems included National Early Warning Score (NEWS/NEWS2), Modified Early Warning Score (MEWS), quick Sequential Organ Failure Assessment (qSOFA), Rapid Emergency Medicine Score (REMS), Cardiac Arrest Risk Triage (CART), and Hamilton Early Warning Score (HEWS) score. The primary outcome was 28-day all-cause mortality. The study also examined whether age, comorbidity burden, frailty, laboratory markers, and hemodynamic parameters were independently associated with 28-day mortality in this population.

Twice vs Thrice Weekly Incident Hemodialysis in Elderly Patients

As Korea is becoming a super-aged society, the number of elderly patients with end-stage kidney disease (ESKD) is expected to increase rapidly. Therefore, the burden on Korean society will also increase. Thrice-weekly hemodialysis is standard for renal replacement therapy. However, this regimen has not been validated for elderly ESKD patients with residual renal function. Elderly patients can have multiple comorbidities such as hypertension, diabetes, cardiovascular disease, and impaired physical activity. Frequent hemodialysis could provoke falls, hypotension, and cognitive impairment. Previous reports have suggested the potential benefit of twice-weekly hemodialysis with incremental increases in frequency when residual renal function decreases. In addition, twice-weekly hemodialysis decreases hospitalization rates in frail patients. Therefore, the investigators hypothesized initiating renal replacement therapy with twice-weekly hemodialysis decreases the hopsitalizatoin rates compared with conventional thrice-weekly hemodialysis in elderly ESRD patients with residual renal function. This study is a pragmatic randomized clinical trial, multicenter study. Study subjects are incident ESRD patients (\>= 60 years old, n=428) with residual urine volume ( \> 500 mL/day) and follow up up to 2 years. Twice-weekly hemodialysis could be incremented according to clinical situations such as volume overload, hyperkalemia and uremic symptom. Primary outcome of this study is hospitalization rate during follow-up. Secondary outcomes include dialysis related hospitalization rate, the length of hospital stay, complication of dialysis,mortality rate and assessments of quality of life, frailty, and cost-utility.

Evaluation of the Clinical Frailty Scale (CFS) as a Risk Factor of Mortality in Adult Patients ≤65 Years of Age Admitted to Intensive Care for Septic Shock.

The aim of the study is to demonstrate that "frail" patients, defined as having a CFS score greater than or equal to 5, and "severely" frail patients, defined as having a CFS score between \[6-7\] as defined by Bagshaw et al (14), constitute an independent risk factor (RF) for mortality. In the same way, as an exploratory study, we will try to find out whether clinical frailty constitutes a risk factor for extending the length of hospital stay, the risk of short/medium-term readmission, as has already been demonstrated for patients admitted to intensive care from all causes (15), or for impaired quality of life. The objective is to have a better understanding of the implications and outcomes associated with pre-hospital frailty in young critically ill patients. This analysis will also help to clarify prognoses and contribute to better decision-making on the intensity and proportionality of care, as well as providing better information and helping to manage the expectations of patients and their families in terms of survival prognosis and subsequent quality of life.

Prevention of Disability in the Frail Elderly Person Through an Innovative Customised and Multidimensional Training Programme

The goal of this clinical trial is to implement a personalized training program to prevent functional decline in frail subjects but not yet disable. The purpose of the project is to test the training in a subject at particularly high risk of entering the disabled condition. A total of 80 frail subjects, divide the participants into two groups "Divida Senso Group" (experimental group) and "Standard of care Group" (Control group) will be recruited. The expected outcome is to slow down a functional decline not only in isolation in the domains trained by the program.

The Effect of Volunteer-Engaged Lifestyle Optimisation Via ICOPE on Sarcopenia in Older Adults (VELO-S)

Sarcopenia prevention and management are highly prioritised goals in the Healthy Ageing agenda. The study aims to: 1) evaluate the effects of the digital-enhanced, volunteer-engaged collaborative care pathway to improve sarcopenia, reduce fall risk, and increase health-related quality of life (HRQL) among community-dwelling older adults with risk of, or diagnosed with, sarcopenia; 2) evaluate whether the volunteers who received health coach capacity training and supported the intervention experienced health benefits across time; 3) explore the engagement experiences and perceived effects of elderly participants with sarcopenia during the program; 4) evaluate the intervention implementation process and effects from the perspectives of social care workers.

Managing Frailty Through Mobilization in Males and Female Inpatients With Cardiovascular Disease

Frailty describes the overall health of a person. Inpatients with cardiovascular problems have a higher risk for frailty - or the sick are more likely to get sicker - causing longer hospital stays, hospital readmission, and death. Females are particularly vulnerable to these problems, generally displaying higher frailty levels than males. In hospital, patients spend almost all their time in bed, and this lack of movement worsens cardiovascular and musculoskeletal health, sometimes lengthening patients' hospital stay and priming them for another cardiovascular event. Prolonged sedentary time may be more detrimental on frailty among females than males. The proposed pilot project will test if an in-hospital General Medicine mobilization program reduces frailty (measure of overall health) in male and female inpatients with cardiovascular disease. A Kinesiologist will provide daily check-ins and promote daily movement (e.g., standing more, resistance bands, physical activity promotion, etc.). The investigators expect both males and females will lower their frailty levels, but given their higher frailty levels in general and because females are typically less active than males, the investigators expect the intervention's effects to be greatest among females. Sixty patients (30 females) will be recruited. Patients with a major heart problem, projected to be in-hospital for at least 3-days, and can independently provide consent. Frailty will be measured using a validated questionnaire. Participants will also be equipped with activity monitors for 24h/d continuous wear to measure amount of time spent stepping, sitting, and lying. Hospital records will be used for length of stay and readmissions. The investigators will compare the outcomes (activity and frailty) between males and females to determine if the intervention impacted each sex differently. This work will guide improved care plans to decrease frailty and improve health outcomes in both male and female patients with heart problems.

Frailty, Hip Fractures and Inflammatory Biomarkers

We ought to investigate if hip fracture patients suffering from frailty have higher inflammatory burden according to simple inflammatory biomarkers.

Preventing and Approaching Crises for Frail Community-dwelling Patients Through Through Innovative Care (PRACTIC)

Preventing and approaching crises for frail community-dwelling patients through innovative care (PRACTIC). Participatory action research in a cluster randomised controlled trial. The primary purpose of this study is to test the effectiveness of an adapted version of a bio-psychosocial person centred model (TIME) to prevent and resolve crises for frail community-dwelling people receiving home care services. The investigators have formulated the following research questions (RQ): RQ1: Can the TIME model adapted for home care service, prevent, and resolve crises in frail people receiving home care services? RQ2: Which participant characteristics or organizational factors are associated with the effect of the TIME model? RQ3: What are the experiences of the users of home care services on how crises were approached during the trial?

Neuromuscular and Multi-Omics Synergy of Combined Creatine × HMB Supplementation Plus Exercise to Improve Muscle Function in Sarcopenic Frailty

Sarcopenia and physical frailty are highly prevalent among institutionalized older adults and are major contributors to functional decline, reduced mobility, and loss of independence. Combined exercise and targeted nutritional strategies have emerged as promising approaches to mitigate these age-related impairments. This randomized, double-blind, placebo-controlled, parallel-group clinical trial aims to evaluate the independent and combined effects of creatine monohydrate (CRE) and β-hydroxy-β-methylbutyrate (HMB), administered alongside a supervised multicomponent exercise program, on physical function, body composition, cognitive performance, and quality of life in institutionalized older adults with physical frailty and sarcopenia. A total of 50 adults aged ≥65 years were enrolled and randomized to one of four intervention groups for 12 weeks: placebo plus exercise, creatine plus exercise, HMB plus exercise, or creatine plus HMB plus exercise. A supplement-free follow-up period will be conducted to evaluate the sustainability of intervention effects. In addition to clinical and functional outcomes, the study incorporates molecular and biological assessments to explore mechanistic pathways underlying functional adaptation and interindividual variability in response to the interventions.
