The main objective of this study is to examine the validity and reliability of the Turkish form of the Enjoyment of Physical Activity Scale-8 (PACES-8) in individuals aged 65 and over with Minimal Cognitive Impairment (MCI).

Validity and Reliability of the Exercise-Related Health Beliefs Attitude Scale in Geriatric Individuals

The main purpose of this research is to test the validity and reliability of the "Exercise Health Beliefs Attitude Scale" (EYSİTÖ), developed by Caz, Paktaş and Yazıcı (2023) for adult individuals, in geriatric individuals aged 65 and over.

Comparison of Hand Grip Strength in Different Shoulder Positions in Geriatric Individuals: Position-Dependent Strength Analysis

The aim of this study is to examine the relationship between hand grip strength, measured in different shoulder positions, and upper extremity muscle strength, and to reveal the clinical significance of position-dependent strength variation.

Successful Aging and Age-related Decline

Recent studies have shown promising cognitive and physical interventions aimed at slowing down ageing-related declines in quality of life, but they lack strong ecological validity (brief durations, unrealistic goals, no real-world application) and has yet to show robust evidence that such interventions are stable and suitable in the long-term. The investigators aim to examine whether these interventions can, over four years, significantly slow down the normal rate of ageing-related decline.

SCORE Study: Comparing Surgery and Rigid Collar Treatment for Odontoid Fractures in Adults Over 70

The goal of this clinical trial is to compare two treatment options-surgery or rigid collar bracing-for unstable neck fractures (odontoid fractures) in adults aged 70 years and older. These fractures are common in older adults and can significantly impact mobility, independence, and quality of life. There is currently no clear evidence to determine which treatment is better for this population. The main questions it aims to answer are: * Does surgery or conservative collar treatment lead to better improvement in daily living, measured by the Barthel Index, after 12 weeks? * What are the differences in pain, disability, and quality of life between the two treatments? The study team will compare patients who receive surgical stabilization with those who are treated with a rigid cervical collar to see which approach supports better functional outcomes and healing. Participants will: * be randomly assigned to either surgery (posterior C1-C2 screw-rod fixation) or conservative collar treatment * attend study visits at 12 weeks and 6 months * complete questionnaires on daily functioning, pain, and quality of life * undergo CT scans and other medical assessments * record collar use (for conservative group) in a diary * be monitored for any complications or changes in treatment (including crossover to surgery if needed) The study aims to include 322 participants to provide evidence on which treatment helps older adults recover better from odontoid fractures with fewer complications and improved quality of life.

Hybrid Group Singing

The overall objective of the planned future clinical trial is to test the investigator's central hypothesis that habitual singing over several weeks, similar to habitual exercise, will lead to sustained and favorable vascular adaptation, thereby lowering cardiovascular disease (CVD) risk. The overall objective of this study is to refine and protocolize the singing interventions and test the feasibility of the future trial design. The investigative team has previously studied solo singing. Collective singing, as in a choir or small group, is associated with a positive sense of social inclusion, well-being, and improved mood, including in older adults.

Validity and Reliability of the Exergame Enjoyment Questionnaire (EEQ) in Turkish

The aim of this research is to adapt the Exergame Enjoyment Questionnaire (EEQ) into Turkish and to evaluate its suitability for the Turkish elderly population through validity and reliability analyses. After the cultural adaptation process is completed, the construct validity of the scale will be evaluated using exploratory and confirmatory factor analyses; its reliability will be assessed through internal consistency coefficients (Cronbach's alpha) and test-retest reliability over time (ICC). Accordingly, the study aims to provide a valid and reliable assessment tool for clinicians and researchers who wish to evaluate individual experiences in exergaming-based interventions.

The Effect of Home Based Fall Prevention Program on Older Adults at High Risk of Falling

Fall prevention programs that implement and evaluate fall rates, balance status, accidents related to falls and hospital admissions, exercise status, muscle strength, fear of falling, and quality of life can be effective interventions for healthy aging by minimizing the risk of falls in elderly individuals. In this doctoral dissertation study, it was aimed to evaluate the effect of a nurse-led home-based fall prevention program on fall rate, balance level, fall risk score, fear of falling, number of hospital admissions due to falls, quality of life, and in-home safety conditions in older adults with high fall risk.

Impact of Esketamine on Delayed Neurocognitive Recovery in Older Patients

Esketamine is frequently used during the perioperative period for supplemental analgesia. Small sample size trials showed that subanesthetic dose esketamine may decrease postoperative neurocognitive complications. However, conflicting results exist and optimal dose of esketamine remains to be determined. This dose-exploring pilot trial is designed to evaluate the safety and efficacy of three different perioperative esketamine dosing regimens in older patients undergoing major non-cardiac surgery. The primary purpose is to explore the optimal dosing strategy that produce maximal neurocognitive benefits with minimal adverse neuropsychiatric symptoms.

Remote Monitoring to Prevent Frailty Progression in the Elderly

Frailty is a frequent condition in elderly, characterized by reduced physiologic reserve, leading to an increased risk for adverse events, such as disability, hospitalization, and death. In particular, it is a multidimensional disfunctional condition, including decreases in physiologic capacity in neurologic control (indicated by diminished ability to perform complex tasks), mechanical performance (e.g. diminished strength), and energy metabolism (e.g. decreased aerobic status due to cardiac or pulmonary diseases or both). All these factors lead to the worsening of quality of life. Focusing on the great impact of this condition in global population and the rising of social/health costs, related to this condition, frailty is earning a great interest from both at political level and European Community. For this reason, developing interventions programs aiming to prevent the progression of frailty towards the independence loss, it is considered a key objective for the improvement of the quality of life. In this context, this pilot study looks at the standardization of a study protocol to develop a useful model for enhancing local care in small population isolates, by remotely monitoring the health status of pre-frail subjects and improving the progression of the frailty condition, in order to support a healthy ageing for future investigation including a larger number of individuals.

Effect of Vegetarien Diet on Protein Digestibility in Young and Elderly Volunteers

Plant proteins are usually less digestible than animal proteins, but they may benefit gut health through effects on the microbiome. The long-term impact of diets rich in plant products on protein digestion and metabolism is still unknown, especially in older adults with higher protein needs. This study aims to compare the digestion and use of pea proteins in young and older adults, both vegetarians and omnivores. Volunteers are divided into four groups: young omnivores, young vegetarians, older omnivores, and older vegetarians. They take part in two clinical investigation days. On the first day, nitrogen retention and protein metabolism is measured after consumption of a pea-based meal. On the second day, amino acid digestibility of pea is evaluated. These results will provide valuable data on how plant proteins are digested and metabolized depending on age and diet. They will also help determine whether aging reduces the availability of plant proteins. This knowledge is important to support nutritional strategies for populations with specific protein needs, such as older adults.

MDT-Based Umbrella Decision Model for Geriatric Lung Cancer Patients

This is a single-center, prospective, single-arm interventional study with historical control, designed to evaluate the clinical value of a multidisciplinary team (MDT)-based decision-making umbrella decision model in elderly patients with lung cancer. A total of 2,000 patients aged 60-90 years with newly diagnosed non-small cell or small cell lung cancer will be enrolled. Each patient will undergo comprehensive geriatric assessment and receive an individualized treatment plan formulated by an MDT comprising thoracic surgeons, geriatricians, oncologists, pulmonologists, rehabilitation therapists, and radiologists. Treatment options include surgery, ablation, stereotactic body radiotherapy (SBRT), neoadjuvant immunochemotherapy, targeted therapy, and best supportive care. The primary outcome is 3-year progression-free survival (PFS). Secondary outcomes include overall survival, objective response rate, quality of life (EORTC QLQ-LC43), incidence of adverse events (CTCAE v5.0), and healthcare economics. Historical controls (2014-2024) will be extracted from hospital records and matched using propensity score matching. The study aims to establish a standardized MDT pathway to improve treatment outcomes and reduce risks in the geriatric lung cancer population.

Elderly Patients Undergoing Surgery During Perioperative Period

The elderly patients have poorer overall conditions and have lower tolerance to trauma, anesthesia, and surgery. Therefore, the incidence of postoperative complications is relatively higher. In non-cardiac surgeries, approximately 20% of elderly patients experience postoperative complications, and the incidence of postoperative delirium (POD) is 23.8%. This may lead to prolonged hospital stays, increased hospital costs, and affect prognosis and even mortality. The investigators plan to conduct a prospective cohort study by systematically collecting biological samples and clinical information of elderly patients during the perioperative period to explore the possible risk factors and pathogenesis of postoperative delirium and postoperative complications in elderly surgical patients, and to construct a risk prediction model for postoperative complications.

Aurora: AI-Based Narrative Intervention to Support Emotional Well-Being in Clinical and Non-Clinical Populations

Aurora is an interdisciplinary project evaluating a chatbot-mediated supportive care intervention designed to promote emotional expression, autobiographical meaning-making, identity processes, and emotional well-being through guided narrative reconstruction. The Aurora system provides a structured, person-centered storytelling process supported by generative AI and human facilitation. Under the supervision of a trained facilitator (licensed mental health professional), participants engage in guided reminiscence and storytelling sessions to co-create a personalized "life book." The chatbot is not a diagnostic or treatment tool; rather, it is intended to support emotional expression, narrative reconstruction, and recovery-oriented processes. The study includes three non-randomized arms implemented sequentially: (1) a single-session arm of healthy adults focused on acceptability, usability, and emotional safety; (2) a four-hour intervention arm of adults with DSM-5 diagnosed mental disorders in residential care; and (3) a four-hour intervention arm of healthy older adults aged 65 years and older. Quantitative outcomes assess affect, mental well-being, and recovery-related constructs. Additional measures include usability, satisfaction, and qualitative feedback. Ecological momentary assessment (EMA) is conducted in Arms 2 and 3.

SENIOR: Stroke Prevention in the Elderly by Patent Foramen Ovale closuRe vs Anticoagulation

Patent foramen ovale (PFO) is an important mechanism of embolic stroke of undetermined source (ESUS). Current guidelines recommend PFO closure for high-risk PFO in patients younger than 60 years, and a recent retrospective cohort study from Taichung Veterans General Hospital has shown that closure is effective and safe in older adults; however, the optimal treatment strategy for those \>60 years and direct head-to-head comparisons of PFO closure versus direct oral anticoagulants (DOACs) remain insufficient. Robust evidence from a multicenter study combining prospective and retrospective cohorts is warranted. The SENIOR study is a multicenter observational cohort registry with a combined retrospective and prospective design. The prospective period is from September 15, 2025 to December 31, 2031, and the retrospective period covers January 1, 2013 to September 1, 2025; target sample sizes are 400 (prospective) and 500 (retrospective). We will enroll adults with ESUS and PFO; the prospective arm will focus on patients aged \>60 years with PFO related stroke. Treatments will be assigned as PFO closure, standard-dose DOAC, or antiplatelet agents (if DOAC intolerance) by local principal investigator. The primary outcome is recurrent ischemic stroke or transient ischemic attack. Secondary outcomes include 6-month functional outcome, all stroke, and serial comparison of atrial cardiopathy changes. Safety endpoints include peri-procedural adverse events (including newly-onset atrial fibrillation), hemorrhagic stroke, and all caused mortality. Clinical presentation, imaging, cardiac testing, biomarker, and genetic data will be collected for stratified and multivariable analyses.

Anesthesia Maintenance With Target-controlled Infusion of Propofol and Remifentanil at Fixed Ratio

The impact of anesthesia depths on early postoperative neurocognitive complications after total intravenous anesthesia (TIVA) remains controversial. In some studies investigating TIVA, anesthesiologists mainly achieve the target depth of anesthesia by adjusting the dose of propofol, whereas the doses of opioids remains comparable between different anesthetic depth groups, possibly resulting inadequate analgesia. This study is aimed to investigate the impact of different anesthesia depths maintained by target-controlled infusion of propofol and remifentanil at a fixed ratio on the incidence of early postoperative neurocognitive complications in older patients undergoing noncardiac surgery.

Prognostic Factors of Hospitalization for Patients Aged 75 and Over in Emergency Department in France - Monocentric Retrospective Cohort Study

A geriatric patient is defined as a patient aged 75 and over who meets certain medical or social vulnerability criteria and is characterised by coexisting physical and/or psychological dependence. The proportion of patients with a geriatric profile in the general population is growing. The average time spent in the emergency department by the elderly population is about 3 hours longer than for patients under 75 years old in France, which is associated with the risk of decompensation of chronic conditions, confusion, falls or agitation. An overnight stay in the emergency department for these patients increases the risk of mortality and the length of hospital stay. Several prognostic scores for hospitalization have been studied in adult populations. The most widely used scores are the Sydney Triage to Admission Risk Tool (START), the Ambulatory (AMB) and the Glasgow Admission Prediction Score (GAPS). Studies have compared these three scores and demonstrated the greater robustness of GAPS. The CalcuLation of the Elderly Admission Risk in the Emergency Department (CLEARED) tool, developed for the elderly population, has lower performance than GAPS. A systematic review of the literature studied the power of GAPS for the geriatric population and highlighted the need for validation in the target population. No validated hospitalization prognostic score was found in France for this population. The research hypothesis is that GAPS would detect hight probability of admission at the time of triage for the patients aged 75 and over in emergency department in France. The primary objective of this monocentric study is to evaluate the prognostic performance of GAPS for the target population (on the group 1). The secondary objectives consist of developing and internally validating a new score (PROFACTHOS) (on the group 2), then performing a temporal validation of PROFACTHOS with comparison to the GAPS (on the group 1), and finally to determine the threshold for classifying patients with a high probability of hospitalization for the score with the strongest discriminatory performance among GAPS or PROFACTHOS. Group 1: Patients aged 75 and over admitted to emergency department from 10/01/2024 to 09/30/2025. Group 2 : Patients aged 75 and over admitted to emergency department from 10/01/2022 to 09/30/2023

Estimate the Safety and Effectiveness of Adjuvanted Influenza Vaccine Among Asian Elderly People When Compared to Non-adjuvanted Vaccines

To compare the immunogenicity, cellular immune response, and safety between adjuvanted (aIIV4) and non-adjuvanted (IIV4) seasonal influenza vaccines in the Taiwanese elderly population with chronic medical conditions.

Catheter Ablation vs Conservative Care in Elderly Patients With Atrial Fibrillation

ACE-AF is a multicenter randomized study in people aged 78 years and older with symptomatic atrial fibrillation (AF). AF is a common heart rhythm disorder in older adults and can cause reduced quality of life and lead to serious complications such as stroke and heart failure. The study compares two established treatment strategies: 1. Catheter ablation (an invasive procedure aimed at reducing AF by electrically isolating triggers in the heart, primarily through pulmonary vein isolation), and 2. Optimized medical therapy without AF ablation (medications for rate and/or rhythm control; AV node ablation with pacemaker may be used if clinically indicated according to routine care). Participants are randomized 1:1 to one of these strategies. All participants will receive an implantable loop recorder (a small heart rhythm monitor placed under the skin) to continuously track heart rhythm and measure AF burden over time. The study has two co-primary outcomes assessed over 24 months: 1. a composite of major clinical events (all-cause mortality, stroke, major bleeding, cardiac arrest, or hospitalization due to heart failure), and 2. patient-reported health-related quality of life (HRQoL), measured by the SF-36 "General Health" domain. ACE-AF will provide evidence to guide treatment decisions for very elderly patients with symptomatic AF and help identify which patients benefit most from an ablation-based strategy compared with optimized medical therapy.

Feasibility of Integrating Local Vibration Into Rehabilitation of Elderly Patients After Hip Fracture

Fractures of the upper end of the femur in elderly patients are the 2nd most common fracture. A fracture leads to a syndrome of psychomotor maladjustment, encouraged by pain and aggravated by hospitalisation. In 2014, 50,000 women and 16,000 men suffered this type of fracture every year. The consequences are serious, with a one-year mortality rate of 20 to 24% and an institutionalisation rate of 25%. In 2015, the direct cost of hip fracture in France was estimated at around €1 billion. In line with the recommendations of the National Institute for Health and Care Excellence (NICE) and the results of meta-analyses, it is recommended that, in the absence of surgical or medical contraindications, patients should be assessed within 24 hours of hip fracture surgery, with a view to initiating early mobilisation and multidisciplinary rehabilitation. It has been shown in healthy subjects that prolonged application of localised vibrations optimises nerve capacity, leading to an increase in maximum voluntary force. For population of frail elderly post-operative patients, this localised vibration technique could accelerate and improve functional recovery, particularly in terms of muscle strength, joint mobility and pain. A reduction in muscle loss is hoped for, with benefits in terms of tolerance compared with neurostimulation. As part of the implementation of the above-mentioned recommendations, the investigators wish to assess the quality of the integration of this technique, already in use in the department on an ad hoc basis, into the organisation of the department and of the patient's care pathway as a complement to the rehabilitation protocols, by identifying the obstacles and facilitating factors. The study will also provide the first estimates of the effect on muscle recovery. The investigator hypothesise that this local vibration protocol can be integrated into the rehabilitation department's work schedule and into the patient's care pathway, and that it will be acceptable to both the patient and the nursing staff.

The Efficacy and Safety of Metformin Intervention in Elderly Overweight or Obesity With Mild Cognitive Impairment

The prevalence of cognitive impairment in elderly obese patients is high, and the burden on families and society is heavy. Early intervention for mild cognitive impairment (MCI) is of great value. Central nervous system insulin resistance plays a role in the pathogenesis of cognitive impairment, and functional magnetic resonance imaging(fMRI) can evaluate cognitive impairment by observing central insulin resistance. Some large database studies of Type 2 Diabetes show that metformin is related to reducing the risk of dementia, but some studies have different conclusions, and there is few related study in elderly obese patients. The investigators speculate that metformin may improve cognitive dysfunction by improving central insulin resistance in elderly obese patients. A prospective, randomized controlled single center clinical cohort study will be conducted on 54 elderly obese patients with MCI. One group will receive metformin and lifestyle intervention, while the control group will receive simple lifestyle intervention. All subjects will be followed up for 26 weeks. Medical history collection, physical examination, and laboratory tests will be conducted before and after intervention, and the Montreal Cognitive Assessment Scale will be used for evaluation. Nasal insulin inhalation combined with fMRI will be used to evaluate central insulin resistance status as an objective basis for cognitive function evaluation. The main purpose of the study is to provide more accurate clinical research evidence for the prevention and treatment of MCI in elderly obese patients, in order to reduce the risk of developing dementia and alleviate the burden on families and society.

Presence of acute pain or injury that may worsen with physical activity. Individuals with progressive neurological conditions such as Parkinson's disease, stroke with severe residual deficits, or multiple sclerosis that impede safe participation in physical activities. Group 1: Progressive Resistance Exercises Participants in the Progressive Resistance Training (PRT) group will engage in a structured exercise program designed to progressively increase muscle strength, balance, and overall physical function. Group 2: Functional Training Participants in the Functional Training (FT) group will engage in exercises that mimic daily activities to improve balance, strength, mobility, and functional independence.

A Study to Evaluate the Effects of the Combination of GI-102 With GIB-7 on Biomarkers of Aging in Healthy Adults and Cancer Survivors

This Phase 2a clinical study (GIANTS-1) aims to evaluate a novel dual-combination strategy using GI-102 and GIB-7 to address key pathological features of aging, including immunosenescence (the aging of the immune system), metabolic dysfunction, and gut-brain-muscle axis dysregulation.
