Zinc Supplementation and Infections in Older Medical Patients

The goal of this clinical trial is to learn about the effect of zinc supplementation once daily for 12 months in older acute medical patients. The main question it aims to answer is: • Can daily zinc supplementation for 12 months increase Days Alive and Out of Hospital (DAOH)? Researchers will compare zinc supplementation to a control group, a group who do not receive zinc supplementation, to see if zinc supplementation can increase Days Alive and Out of Hospital, reduce antibiotic use, readmissions and mortality. Participants will take 22 mg zinc supplementation once daily for 12 months or not. The researchers will draw data on readmissions, antibiotic use and mortality during the 12 months follow-up period.

How Video Game Therapy Affects Thinking and Emotions in Older Adults With Cognitive Impairment

Golden Gamers Go is running a study together with Rey Juan Carlos University to better understand how videogames can help older adults, especially those with memory problems or cognitive decline. The study takes place in real care settings, such as day centers, and involves around 45 older participants. Over two months (with a possible follow-up period), participants take part in two to three sessions per week using video games on PlayStation. These are not special "health games," but popular, commercial video games that have been carefully selected and adapted to be easy to use, enjoyable, and meaningful for older adults. The goal is to see whether playing these games can help improve thinking abilities and also how participants feel during the activity - for example, if they are more engaged, motivated, or emotionally positive. This study builds on previous experience where this approach has already shown promising results in increasing participation, motivation, and overall wellbeing. By carrying out this research, Golden Gamers Go aim to better understand how meaningful and enjoyable activities like videogames can support healthier and more active aging.

Optimizing Care Transition Process for Older Colorectal Surgery Patients

The goal of this study to test if a care transition intervention designed for older colorectal surgery patients would improve outcomes after discharge. It will assess the feasibility of the intervention.

Promoting Walking Among Older Adults Through Nostalgia-Based Messages and Step-Monitoring

Physical inactivity increases substantially after age 60 and represents a major public health challenge in older adults, as it is linked to increased risk of functional and cognitive decline and aging problems. Walking is one of the most accessible and recommended forms of moderate physical activity for this population. However, promoting sustained engagement in walking remains difficult, as traditional informational approaches often fail to activate personally meaningful motivations. This study tests whether nostalgia-based persuasive messages can promote walking by leveraging psychologically meaningful connections with the past. Nostalgia, a predominantly positive, bittersweet emotion associated with meaningful past experience, has been shown to strengthen self-continuity, self-esteem, and psychological well-being in older adults. Building on this framework, the present trial examines whether nostalgic memories can strengthen motivation to engage in walking behavior. In addition, the study investigates whether combining nostalgia-based messaging with a self-regulation strategy (daily step monitoring) enhances intervention effectiveness. Self-monitoring is a well-established behavioral technique that supports goal pursuit by increasing awareness and feedback. Using a randomized controlled 4-arm factorial design, the study compares the effects of nostalgia-based messages, step-monitoring, their combination, and an attention control condition on walking behavior and its psychological determinants. A national sample of 1,000 Italian adults aged 65-74, recruited through a certified panel provider (Ipsos) and balanced for age, gender, and geographic region, will be randomly assigned to one of the four conditions. All participants will receive one message per day for 14 days via a mobile application. Participants in the self-monitoring conditions will also be asked to track and report their daily step count using a pedometer application. Behavioral, psychological, and process measures will be collected at baseline, post-intervention, and follow-up. The study aims to provide experimental evidence on the role of nostalgia as a motivational driver of health behavior change and to clarify whether combining affective and self-regulatory strategies enhances intervention effectiveness in older adults.

SCT-Based Health Promotion in Older Adults

This study will be conducted to compare the effects of Peer- and Nurse-Led Health Protection and Promotion Training Programs Based on Social Cognitive Theory (SCT) on the health behaviors of older adults. This research will be carried out in two stages as a mixed-methods study with an embedded mixed-method design. The first stage has been planned as a parallel two-arm non-randomized experimental study. This stage will be conducted between October and December 2025 in two separate elderly homes where older adults are densely located in the Muratpaşa district of Antalya province. The sample size has been calculated as 108 older adults (Intervention-1 Peer Leadership: 54, Intervention-2 Nurse Leadership: 54). In the Intervention-1 group, the intervention will be implemented for 12 weeks through the Health Protection and Promotion Training Program Based on SCT under peer leadership, and the same interventions will be carried out in the Intervention-2 group under nurse leadership. Outcomes will be measured before the intervention and 12 weeks after the intervention using the Elderly Health Promotion Scale, Health Protection and Promotion Behavior Checklist, General Self-Efficacy Scale, and Health Seeking Behavior Scale. In the second stage, in order to evaluate the intervention process and experiences multidimensionally, it is aimed to deeply understand the experiences of older adults receiving peer-led intervention, older adults receiving nurse-led intervention, and peer leaders by using multiple data sources within the framework of qualitative research and a phenomenological approach. In the qualitative phase, the data will be collected based on the maximum variation sampling method through face-to-face in-depth individual interviews using semi-structured interview forms in the workshops of both elderly homes in January 2026.

Respiratory Exercises in Frail Elderly COPD Patients

Purpose: This study evaluated the impact of a structured intervention on frailty, lung function, physical capacity, and dyspnea in elderly COPD patients. COPD, common in older adults, often coexists with frailty, which worsens health outcomes. While pulmonary rehabilitation improves function, its effect on frailty remains unclear. Procedures: A total of 66 patients with a confirmed diagnosis of COPD were randomly allocated into two equal groups: an intervention group (n=33) and a control group (n=33). Participants in the intervention group completed a six-week pulmonary rehabilitation program. Both baseline and post-intervention evaluations comprised spirometric measurements (FVC, FEV1, FEV1/FVC ratio, FEF25-75, and PEF), the Edmonton Frailty Scale (EFS), the six-minute walk test (6MWT), oxygen saturation levels, and assessments of dyspnea severity. Results: Significant improvements were observed in the intervention group in FVC, FEV1, FEV1/FVC, and PEF (p\<0.05). Total EFS scores and subdimensions such as mood, general health, and cognitive status also improved significantly (p\<0.05). Additionally, the intervention group showed increased 6MWT distance, higher oxygen saturation, and reduced dyspnea scores post-intervention (p\<0.05), with minimal changes in the control group. Conclusion: The findings suggest that pulmonary rehabilitation not only enhances pulmonary function and exercise capacity but also reduces frailty severity in elderly COPD patients. Integrating frailty-focused strategies into routine COPD management may improve outcomes and quality of life in this population.

Predictors of Climate Change Health Literacy in Older Individuals

The aim of this study is to identify predictors of climate change health literacy in older adults.

Technology-based Hand Rehabilitation in Older People

Because hand and cognitive functions decline in the elderly, intervention programs addressing these problems are necessary. In recent years, creating rehabilitation programs using technology has gained popularity. The aim of this study is to examine the effects of technology-based rehabilitation using LMC (Light Mood Enhancer) and dual upper extremity tasks on joint position sense, grip strength, functionality, and executive functions in elderly individuals; and to compare these effects with those of an exercise program performed solely with an LMC device and a control group consisting of a hand rehabilitation program performed with a physiotherapist. The research is a randomized controlled trial and will consist of 3 groups. After randomization, individuals' joint position sense, gross and fine grip strength, functionality, and executive functions will be evaluated. Evaluations will be performed twice, at the beginning and end of the 8-week program.

Effects of Breathing Exercises on Cognition in Older Adults

The goal of this interventional clinical trial is to investigate the effects of breathing exercises added to balance training on cognitive function in individuals aged 65 years and older. The main questions it aims to answer are: Do breathing exercises affect cognition? Do different breathing exercises affect cognition in different ways? Researchers will administer two different breathing protocols and evaluate cognition before and after each protocol. Participants will take part in an 8-week program consisting of sessions that include 30 minutes of balance-based exercises and 15 minutes of breathing exercises. Sessions will be held twice weekly under the supervision of a physical therapist.

The Effect of Virtual Reality in Older Adults

This research will be conducted to examine the effects of virtual reality on sleep quality and comfort in older adults. This research will be conducted as a single-blind, randomized controlled experimental study with a pre-test-post-test design, involving application and control groups, to examine the effect of virtual reality on sleep quality and comfort in elderly adult patients hospitalized in the internal medicine and surgical clinics of Kars Harakani State Hospital between December 15, 2025, and December 31, 2026. To inform older adults, and after obtaining informed consent, the study will be administered using a "Senior Adult Descriptive Information Form" containing demographic information about older adults, the Standardized Mini Mental Test which assesses the cognitive level of older adults, and a "Senior Adult Monitoring Form" to track any potential side effects of the intervention. The Senior Adult Descriptive Information Form, the Richards-Campbell Sleep Scale (RCSQ), and the VAS Comfort Scale (VCS) will be used to collect data for the study. Data will be collected from elderly adults hospitalized in the internal medicine and surgical clinics of Kars Harakani State Hospital who meet the research criteria. They will be shown 360-degree video images (Chitra and Eremita 2023; Eremita and Chitra 2024) for 20 minutes each night during their hospitalization hours using VR Shinecon virtual reality glasses.

Healthy Ageing: a Feasibility Study to Evaluate Digitally-enabled Ways to Support Healthy Ageing

The goal of this clinical trial is to learn if it is feasibility to conduct a trial of two digitally-enabled interventions that support older adults to adopt healthy behaviours. It will also learn about the safety of this digital intervention. The main questions it aims to answer are * How acceptable and feasible are the trial, intervention and control groups in assessing outcomes * What is the estimated effect of the interventions? Researchers will compare Smart devices with a bespoke 'Healthy Habits' application and three healthy habit coaching and data feedback modules, to a group with smart devices and standard off-the-shelf feedback application, to a control group that will receive an education leaflet to adopt healthy behaviours. Participants will: * Use sensors and the 'Healthy Habits' application for 3 months followed by standard application for 3 months, or sensors and standard application for 6 months, or control * Either home visit or in-centre visit once every 3 months for assessments and online health questionnaires * Complete daily diary of any healthcare use

Feasibility of Virtual Reality-assisted Ergometer Cycling in Addition to Regular Rehabilitation During Municipality-based Inpatient Rehabilitation Care

VR-C-REHAB is a single-group pilot and feasibility study examining the practicality of implementing virtual-reality-assisted ergometer cycling as an adjunct to usual municipal inpatient rehabilitation for older adults (≥65 years). Many individuals admitted to temporary inpatient care present with low physical activity levels and fluctuating motivation, reducing the achievable exercise dose. Virtual reality may enhance engagement, enjoyment, and adherence, but its feasibility in this setting must be evaluated before conducting a future effect trial. The primary objective is to determine whether participants can achieve an adequate exercise dose, defined as the proportion of completed VR-cycling sessions out of those offered (target: ≥75%). Secondary feasibility outcomes include recruitment rate, safety and acceptability, and total cycling time. Exploratory outcomes include change in the 10-Meter Walk Test and session-level motivation (0-10). The intervention consists of 20 minutes of VR-assisted cycling, three times weekly for up to four weeks, delivered alongside standard rehabilitation. Data are collected at baseline, during each session, and at completion. Analyses are descriptive, focusing on the precision of feasibility estimates. Progression criteria (Go/Amend/Stop) are based on adherence, recruitment, and safety. The results will inform the design and implementation of a subsequent controlled study.

Cognition in Older Adults With Cancer Receiving Systemic Anti-Cancer Therapy

The majority of cancer diagnoses occur in adults age 65 years and over. This population is also rapidly expanding. There is a growing need for increased understanding about the potential impact of various newer therapies on common geriatric impairments in this group. The aim of this study is to examine how feasible it is to carry out a study of cognitive function in older adults (age 65+) who are newly commencing anti-cancer treatments, specifically 'immune checkpoint inhibitor' therapy, over time. Participants in the study undergo four tests of memory and concentration every six weeks for a six month period. Additionally, the researcher will gather information about the participants' non-cancer therapy medications, physical and psychological symptoms, day to day functioning and any changes to these factors over time. The purpose of the study is to examine a) recruitment, retention and engagement of participants to study procedures; b) to gather preliminary information about cognitive function in older adults commencing immune checkpoint inhibitor treatments and potential associations with cognitive decline over time.

Improv Music Therapy for Older Adults

Older adults and their care partners will participate in music therapy sessions for approximately 8 weeks. Before and after the 8 week study period, participants will fill out questionnaires about their mood, stress levels, and emotions. During the music therapy sessions, they may be observed or asked questions about the music therapy sessions.

CBT-I in Older African American Adults

Sleep problems, like insomnia, are common in older African Americans. About 25% of older adults in the US have at least 2 symptoms of insomnia, such as having trouble falling asleep, staying asleep, or getting good sleep for a month or more. Cognitive Behavioral Therapy for Insomnia (CBT-I) is a recommended non-pharmacological treatment for insomnia. Unlike medicines that might only help for a short time or have many side effects, CBT-I deals with the root causes of insomnia. It helps people change how they think and act about sleep, leading to better habits and attitudes. This can make sleep better for a long time, even after the treatment is over. While CBT-I is commonly used among adults with insomnia, its benefits among older adults and specifically older African American adults are not well understood. Thus, the current pilot study will investigate the feasibility of CBT-I in older African American adults and establish preliminary evidence for the potential benefit of CBT-I on sleep as well as cognition in this population. For this study, participants will be asked to complete pencil-and-paper questionnaires, psychological tests of cognition, 7-day actigraphy, 2 nights of at home sleep monitoring, which collects specific sleep measures such as brain waves and sleep stage timing, and computer-based neuropsychological tests before and after intervention. Study interventions will consist of 8 weekly sleep training sessions via Zoom or a single session of education on strategies to improve sleep quality. Sleep training sessions will include education about strategies to improve sleep quality, changing thought process that contribute to insomnia, training the brain on the optimal sleep environment, and reducing sleep initially to establish a consistent sleep schedule before increasing sleep time. Three months after the post-intervention visit, participants will be asked to come back in for a follow-up evaluation which consists of complete pencil-and-paper questionnaires, psychological tests of cognition, 7-day actigraphy, 2 nights of at home sleep monitoring, and computer-based neuropsychological tests.

Virtual Reality-Enhanced Behavioral Activation for Older Adults With Depression

The primary aims of this study are to assess the feasibility, acceptability, and tolerability of using an immersive virtual reality (VR) headset to engage in behavioral activation (BA) for older adults diagnosed with major depressive disorder (MDD). The secondary aim of this study is to explore the efficacy of using VR to enhance BA therapy in a clinical MDD older adult population.

Modifying the Geriatric Acute & Post-acute Care Coordination Program for Fall Prevention in the Emergency Department for Telehealth

The goal of this clinical trial is to determine the feasibility of eGAPcare, a telehealth modification of the GAPcare fall prevention intervention, in older adults in a community emergency department. The main questions it aims to answer are: * Can telehealth physical therapy and pharmacy consultations be conducted in a community emergency department? * Does the telehealth modification of GAPcare decrease recurrent falls at 6 months? Participants will * Receive telehealth physical therapy and pharmacy consultation while in the emergency department * Participate in follow-up visits over the phone for 6 months following the initial emergency department visit * Complete study questionnaires delivered by study staff.

Self-Compassion, Self-Efficacy, and Health Outcomes in Older Adults

This cross-sectional observational study aims to examine the relationship between self-compassion, self-efficacy, postural awareness, pain, quality of life, and health-promoting lifestyle behaviors in adults aged 65 years and older. Data will be collected using validated self-report questionnaires administered online. The findings are expected to contribute to a better understanding of psychological factors associated with physical and behavioral health outcomes in older adults.

The Effect of a Passive Hip Exoskeleton on Daily-life Fatigue in Older Adults

This crossover study investigates whether a passive lower-limb exoskeleton (Exoband) can reduce perceived exertion during everyday mobility tasks in older adults. Participants complete the fatigue protocol- a structured sequence of daily challenging tasks (e.g., overground walking, stair and slope walking, obstacle avoidance)-once with the Exoband and once without it, in randomized order and separated by a one-week washout period. During each session, distance covered until fatigue, rate of perceived exertion, physiological and gait parameters are recorded. The aim is to determine whether exoskeleton assistance enhances mobility performance and reduces functional fatigue across older adults.

Healthcare Services for Older People Who Have Fallen With Potential Head Injury

Every year, one in three older people (\>65 years old) experience a fall. Older people may have long-term health conditions and take medications that can increase their risk of bleeding (blood thinners). The UK national guidelines recommend that older people who are on blood thinning medications should have a CT head scan considered due to concerns of a brain bleed if they have hit their head after a fall. Many older people are therefore brought into hospital for assessment. However, the risk of bleeding in the brain is very low especially if older people do not have any symptoms such as loss of consciousness, weakness, headaches or vomiting. Some people could experience long waits in the emergency department or end up being admitted to hospital unnecessarily. This could worsen mobility, cause confusion, pressure sores or infections in older people. More importantly, older people should have a comprehensive falls assessment to reduce their risk of future falls and have their medications reviewed after experiencing a fall. These assessments could potentially take place in their own homes if they prefer, rather than in hospital. Yet, current healthcare services outside the hospital setting may not be set up to manage an older person after fall. Using an online survey, the investigators want to understand how current healthcare services in the Hampshire and Isle of Wight (HIOW) region work to look after older people who have had a fall. The study will focus particularly on older people taking blood thinning medications who may have a head injury but do not have any symptoms. The investigators will ask NHS workers what their role is, where they work and what they do when assessing an older person who has fallen if there is a concern about head injury. The survey will also ask participants to describe what challenges they may face, and if they have any suggestions to improve the care for older people. This study will help the investigators understand what services are available in our current healthcare system for older people on blood thinning medications who have fallen and may have a head injury. The investigators hope that the results will help improve how healthcare services can work together with older people and their closed ones to provide care based on what matters most to them in their preferred place of care. This could reduce unnecessary use of emergency services and hospital admissions for older people.

Targeting Muscle Strength Loss Due to Hospitalization in Older Adults by Blood-flow Restriction Combined With an Electromyography-driven Serious Game.

This study investigates a new training method designed to help older adults preserve their muscle strength during hospitalization. When older adults are admitted to the hospital and spend long periods in bed, their muscles can weaken very quickly. This condition is known as hospital-associated disability (HAD), and it can lead to longer hospital stays, reduced independence, and an increased risk of complications or even death. Conventional strength training with heavy weights is often too demanding or unsafe for frail patients, especially just after surgery or illness. As a safer alternative, this study combines light muscle exercises with a medically validated technique called blood flow restriction (BFR), which gently reduces blood flow to the leg to boost the effects of light exercises. To make training more engaging and personalized, the GHOSTLY+ system was developed. This system consists of a game played on a tablet that responds to muscle activity through sensors placed on the skin. While playing, patients perform isometric muscle contractions (exercises where the muscles tighten without moving the joint) that help to maintain and rebuild strength. The system was carefully designed in collaboration with patients and therapists, and it has already been tested in a smaller pilot study at UZ Brussel. The current study is a multicenter randomized controlled trial, taking place at UZ Brussel, UZ Antwerpen, and UZ Leuven. A total of 120 patients aged 65 or older will be recruited, all of whom are hospitalized and are unable to bear weight or transfer (e.g., from lying to seated position). Participants will be randomly assigned to one of two groups. One group receives standard physiotherapy. The other group receives standard therapy plus the GHOSTLY+ training program. Those in the GHOSTLY+ group will train at least five times per week for two weeks, or until discharge from the hospital. Each training session lasts approximately 30 minutes and involves three sets of 12 muscle contractions, guided by the game. The difficulty is adapted to the individual's muscle strength, which is measured at the beginning of the training using a built-in calibration protocol. During the session, a smart cuff is applied to the upper leg to partially restrict blood flow - a technique shown to safely enhance muscle adaptation. The cuff is inflated to 50% of the individual's arterial occlusion pressure and deflated after the session ends. Before beginning, participants receive a short training session with a physiotherapist. Our pilot study (Debeuf et al., 2025) shows that most patients can use the system independently after about one hour of instruction. Measurements and evaluations take place at three timepoints: before starting the training, after one week, and again at discharge. The main goal is to assess leg muscle strength, which will be measured using a handheld device called a dynamometer. In addition, researchers will collect information on: * Muscle mass, via ultrasound of the thigh muscle * Functional capacity, using a 30-second sit-to-stand test and a walking scale (Functional Ambulation Category) * An index of independence in activities of daily living (Katz scale) * Cognitive functioning, using the Mini-Mental State Examination (MMSE) * Time spent bedridden and total length of hospital stay * Therapy adherence and user experience, via usage data and questionnaires * Muscle activity signals, such as fatigue, recorded during gameplay * Implementation outcomes (collected via surveys, interview, site logbooks) The study will also assess how easily the GHOSTLY+ system can be implemented in real hospital environments. This includes evaluations of user satisfaction, therapist feedback, and how consistently the system is used across hospital settings. Information will be gathered through structured interviews, surveys, and data logs from the app. These insights are crucial to understanding whether GHOSTLY+ can be broadly adopted in other hospitals in the future. Blood flow restriction training is considered very safe when applied correctly and is already used in rehabilitation clinics and sports medicine worldwide. Over 300,000 sessions have been conducted internationally, with a very low rate of complications. Minor discomfort, such as temporary tightness or muscle fatigue, may occur, but the risk of serious side effects is extremely small. By participating in this study, patients may benefit from improved muscle strength, reduced time spent in bed, and greater physical independence at discharge. The study also contributes to the development of more effective and enjoyable rehabilitation methods for older adults in hospitals.
