Age Problem

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.

The goal of this clinical trial is to determine the efficacy of Clemastine Fumarate in the presence of engineered sound to treat age-related central auditory processing disorder (CAPD). This disorder impacts 800M patients worldwide, including \~1/3 people over 40 years of age and \~1/2 people over 65, resulting in an inability to hear in noisy environments. The primary hypothesis this study aims to test is: engineered sound, driving localized neural circuit activity, will enable Clemastine Fumarate to mature Oligodendrocyte cells and thus remyelinate these activated neural circuits. This Localized Oligodendrocyte Optimization Therapy (LOOT) was highly effective in preclinical animal studies so this clinical trial aims to answer if this therapy will translate to humans. The study is an adaptive design intended to compare the efficacy of the drug in the presence or absence of the engineered sound for improving hearing in noise ability. Trial participants will be tested for hearing thresholds and ability to isolate a sound signal from background noise. If they meet the inclusion criteria, they will be enrolled into one of the four arms of the study and undergo the proposed one-month treatment (drug and sound or respective placebos). After the treatment period, trial participants will be tested again for hearing thresholds and their ability to isolate s sound source of interest from background noise. The hypothesis to be tested in this clinical trial is that the one-month treatment will significantly improve the participant's ability to isolate a sound source of interest from background noise. The design has four arms, drug+sound, placebo+sound, drug+white noise, and placebo+white noise. Based on our preclinical data, control arms are all expected to show identical results, thus our adaptive design includes interim analyses to allow for dropping of two of the three placebo arms should the preclinical results be replicated as anticipated. We will also monitor each participant's general health during the duration of the clinical trial, which will be done by performing a number of blood tests, an EKG and a general physical before and after the one-month treatment period. We expect no significant changes since participants will take the drug for the one-month period at dosages already demonstrated safe in several Phase II studies of multiple sclerosis. Similarly, the engineered sound will be listened to for one hour per day during this month at sound intensities well below threshold that might cause noise-induced hearing damage.

The goal of this interventional study is to asses echocardiographic variations in emergency department's elderly patients receiving red blood cell transfusion. The main questions it aims to answer are : * is there a modification of echocardiographic parameters after red blood cell transfusion ? * which parameter is the most impacted by red blood cell transfusion ? Participants will have a transthoracic echocardiography before, just after and 15 minutes after red blood cell transfusion.

The goal of this observational study is to learn about difference related to age and gender in patients admitted to emergency department.

This study is a fully-powered randomised controlled trial and an essential follow-up study of our pilot work. The 21-style specific dance intervention to improve the balance and reduce the risks of falls (SDIIBRF) was suggested to be interesting, achievable, and compliable, according to the participants' feedback in the investigators' pilot work. Due to the expertly-designed and specifically-designed characteristics of the 21 dance styles in the SDIIBRF for improving balance and reducing risk of falls in older adults, the dance steps included in the SDIIBRF are unique and are largely different from the dance interventions that have already been reported in the literature. Based on the encouraging results of the preliminary efficacy in the investigators' pilot work and dance being a mind-body exercise, the investigators hypothesise that the specific dance programme will be efficacious in reducing the frequency of falls (primary outcome measure), improving the balance (secondary outcome measure for the main fall risk factor), and reducing the physical and psychological fall risk factors (secondary outcome measures) in Hong Kong's at-risk older adults. The findings could provide important new evidence for a feasible option for older adults as an innovative fall prevention exercise programme. The research question is "Can the 21-style SDIIBRF reduce the frequency of falls, improve the balance, and reduce the fall risks in Hong Kong's older adults at moderate to high risk of falling? Therefore, the aim of this proposed study is to examine the efficacy of the 21-style SDIIBRF in reducing the frequency of falls, improving the balance, and reducing the fall risks in Hong Kong's older adults by comparing it with a wait-list control.

Exercise Rehabilitation (ER) is widely used and effective in the treatment of chronic diseases; however, patients do not adhere to ER programs. Tele-rehabilitation is effective and often used to support and improve patient adherence. Thus, the ADEPINA device could be a promising solution for the individualized management of patients by their therapists. The aim of the study will be: a) To assess functional improvement, measured by the 6-minute walk test (6MWT) after the 12 weeks ER program in people with chronic disease. Additionally, the study will assess the individualized program' adherence and his effect on patients' physical fitness and quality of life. Methods: Fifty patients will follow individualized ER sessions to their patients (with chronic diseases) using the ADEPINA device, 2 to 3 times per week for 12 weeks. At the end of the intervention, the investigator will assess patients' lower limb strength (with sit to stand test), dynamic balance (Timed up and go test), patients' adherence to the ER program by evaluating the usage time of the system by participants, the treatment credibility and participant expectations for improvement will be assessed with the French version of the Credibility and Expectancy Questionnaire. The investigator will also evaluate the patients' quality of life (using the "World Health Organization Quality of Life" (WHOQOL) scale) at the beginning and end of the intervention. Discussion: This interventional pilot study could have positive impacts for participants and explore gaps in the current literature regarding the individualized telerehabilitation program' feasibility.

This is a community-based prospective cohort study in China. The study has been initialized in 2024 and included older residents. The goal of this observational study is to explore the risk factors related to disability and dementia in the elderly Chinese community population, and develop a risk prediction model for disability and dementia.

This is a community-based prospective cohort study in Beijing, China. The study has been initialized in 2023 and enrolled older residents. This study aims to develop disability risk assessment standards and an early warning model for older adults.
