Filter by:Background: Tai Chi Chuan, a Chinese martial art style, is a mind-body modality that has shown positive impacts on health markers in various populations, particularly older adults. This study aims to investigate the effects of a 12-week program of Tai Chi Chuan exercises based on the Yang 16-movement form and walking on older adults' physical and mental markers. Methods: This study is a randomized, single-blinded, two-arm, parallel, superiority trial. Forty older adults between 60 and 75 years old who are not engaged in any systematic strength and aerobic training program will be recruited. Candidates with language and cognitive problems, a history of cardiovascular diseases (except controlled hypertension), osteoarticular limitations and fractures, severe injuries, and prosthetic placement in the last six months will be excluded. Participants will be randomly allocated on a 1:1 ratio to a 12-week intervention with Tai Chi Chuan and walking two times per week, or an active-control group with walking two times per week. Physical measures will be muscle strength (i.e., knee extensors maximum strength and lower limbs functional performance -primary outcomes-, dynamic knee extensors endurance, handgrip strength, back-leg-chest strength), functional capacity, static balance, muscle thickness and muscle quality of quadriceps. Mental measures will be quality of life, sleep quality, cognitive function, and depressive and anxiety symptoms. Outcomes will be measured before and after 12 weeks of intervention. The analysis plan will use an intention-to-treat approach and protocol criteria. Discussion: The conceptual hypothesis is that the intervention training program with Tai Chi Chuan and walking will lead to greater improvements in both physical and mental parameters due to its multi-component character compared to the walking active-control group.
This is a randomized, controlled, double-blinded, within-subject (split-face), multicenter, prospective study to investigate whether RHA® Redensity with new anesthetic agent is non-inferior to RHA® Redensity with lidocaine in terms of injection site pain felt by the subject during injection. At screening, the Principal Investigator (PI) evaluated subjects' perioral rhytid severity (using the Perioral Rhytid Severity Rating Scale; PR-SRS) to confirm eligibility and to establish a pre-treatment score for assessing aesthetic improvement. At Visit 1, RHA® Redensity with new anesthetic agent was administered in a random sequence (first or second injection) and side of the mouth (left or right) and RHA® Redensity with lidocaine was administered to the other side. Study subjects and the PI injecting study devices were blinded. Immediately after injection of an upper perioral quadrant, subjects rated the injection site pain experienced during injection using a 100 mm Visual Analog Scale (VAS). Injection site pain in each side of the mouth was also assessed at 15, 30, 45 and 60 minutes after injection of the upper quadrant. Safety evaluation consisted of AE assessments, a 30-day CTR (Common Treatment Response) diary and a follow-up call performed by the study site at 72 hours after injection. Subjects attended Visit 2 (30 days post-injection) where effectiveness and safety assessments were conducted. Subjects who presented with an unresolved clinically significant device related AE at Visit 2 received a optional follow-up phone call no later than 30 days after Visit 2. If the clinically significant AE remained unresolved, the Investigator requested that the subject attended the optional in-clinic follow-up visit (i.e., Visit 3) within 5 working days. Follow-up of the clinically significant AE continued until the AE was resolved or the TI determines that additional follow-up was not necessary.
The overarching hypothesis to be evaluated using this protocol is that age-related hearing loss (ARHL) leads to shifts in the functional spatial boundaries between segregated and integrated auditory streams, and that hearing aid intervention that relies on directional processing schemes is most effective for those that have the poorest spatial sensitivity. One key component of the research design is to measure both behavioral and neurophysiological indices of an individual's spatial segregation boundary. The second key component is to measure the cost or benefit associated with hearing aid intervention in older hearing-impaired listeners. The final component is to relate cost and benefit of hearing aid intervention to spatial sensitivity measures that might predict the efficacy of clinical intervention.
We will use cognitive exams, perceptual tasks, brain imaging, peripheral psychophysiology, and surveys to investigate the persisting effects of psilocybin on cognition, predictive coding, and affect in healthy older adults. We will measure changes in these measures by comparing baseline to one-week and one-month post-treatment. Participants will be randomly assigned to receive a dose of psilocybin in a range from microdose to moderate-to-high dose. Dose response will be assessed. Anatomical magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) will be used to assess changes in brain structure, while functional magnetic resonance imaging (fMRI) will be used to quantify changes in functional brain activity. We will assess whether changes in these brain measures underlie observed changes in cognition, predictive coding and affect.
Background: Aging leads to an alteration in the immune response, characterized by a chronic inflammatory state, and a progressive decrease in muscle quantity and quality, a situation that increases in women and in the presence of obesity. With respect to muscle quality, intramuscular infiltration of adipose tissue has been considered a relevant parameter, involved in the relationship between aging-obesity-inflammation. As a therapeutic strategy, physical training with resistance exercises (or also known as strength training) has been shown to be effective in increasing skeletal muscle mass in this age group. However, its role on muscle quality in normal-weight versus obese older women has not been fully addressed. Hypothesis: A 12-week resistance exercise training program is effective in improving muscle quality, immune response and physical performance in normal weight and obese older women. In addition to the above, the investigators hypothesize that women with obesity will present greater baseline alterations, so the percentage of change will be higher compared to older women with normal weight after the training program. Goals: The primary aim of this study is to evaluate the effects of a 12-week resistance exercise training on muscle quality (infiltration of intramuscular adipose tissue), immune response and physical performance in older women between 60 and 79 years of age with obesity compared to older women with normal weight of the same age range. Methodology: The present clinical trial will consider 2 groups of older women between 60 and 79 years old: normal weight (BMI=18.5 to 24.9 kg/m 2 and % fat <25.9) and obese (BMI =30 to 39.9 Kg/m 2 and fat % >32). Participants will perform 12 weeks of training with resistance exercises 3 times a week. Before and after training, intramuscular infiltration of adipose tissue (echogenicity) will be measured by ultrasound, followed by aspects of muscle architecture (muscle thickness, penile angle and fascicle length) and functional parameters of muscle quality (maximum strength determined by 1 repetition maximum-1RM, maximum voluntary isometric strength of knee extensors through a lower limb force and power transducer). Finally, fasting blood samples will be obtained (immune response) and physical performance, body composition, physical activity level, and quality of life will be evaluated.
Population ageing is a global problem. With ageing, involutionary changes and multimorbidity increase, leading to limitations in the performance of daily activities and disability. Proposed by the World Health Organisation (WHO), the geriatric core set is a set of categories of the International Classification of Functioning, Disability and Health (ICF) that allows for a comprehensive assessment of a person of geriatric age. In Poland, the geriatric core set has not yet been adapted and validated. Therefore, the aim of this study is the cultural adaptation and validation of the Polish version of the ICF-based categorical profile for the assessment of older people.
The primary objective of this clinical trial is to assess the clinical efficacy and safety of the Buyuan Zhixiao Formula in treating elderly patients with diabetes and multiple metabolic disorders exhibiting symptoms of renal deficiency and blood stasis. Furthermore, this study aims to intervene in high-risk factors to prevent arteriosclerosis and to investigate the clinical efficacy of the Buyuan Zhixiao Formula in the prevention and treatment of cognitive impairments. The main questions it aims to answer are: 1. What are the clinical effects of Buyuan Zhixiao Formula, including lowering blood sugar, lowering blood pressure, lowering lipids, and treating obesity? 2. Can Buyuan Zhixiao Formula improve cognitive impairment in diabetes? Researchers compared Buyuan Zhixiao Formula with a placebo (a drug that looks similar but contains only 10% of the active ingredients) to see if the drug Buyuan Zhixiao Formula can treat elderly people with diabetes and multiple metabolic disorders. Participants will: 1. Take the drug Bu Yuan Zhi XiaoFormula or placebo every day for 6 months；Follow-up for 6 months； 2. Check fasting blood sugar and 2-hour postprandial blood sugar every month; check HbA1c, blood lipids, vascular function, and cognitive impairment serum markers every 3 months; 3. Conduct scores on TCM symptoms, cognitive ability, nutritional status and other scales and adverse events; 4. Urine and serum samples were collected before and after treatment;
Recruitment on the RAV pole in consultation or day hospital. Competitive recruitment of subjects > 60 years of age respecting a male/female ratio = 1.
The goal of this observational study is to learn about current practices for the acute neuropsychiatric management of older adults during emergency department (ED) visits. Researchers will compare current standard of care practices with implemented guideline practice to see if standardized medication guidelines help reduce the usage of antipsychotics and/or benzodiazepines during acute presentations. The main questions this study aims to answer are: - How many older adults are receiving antipsychotics or benzodiazepines during emergency department visits? - Why are older adults receiving antipsychotics or benzodiazepines during emergency department visits? - How many older adults who receive antipsychotics or benzodiazepines during emergency department visits have an underlying cognitive or movement disorder? - What effects does administration of antipsychotics or benzodiazepines during emergency department visits have on patient outcomes in older adults and adults with neurocognitive disorders? - Does implementation of standardized medication guidelines help reduce the usage of antipsychotics and/or benzodiazepines during acute presentations?
The purpose of the study is to compare the effectiveness of Divomed in organising complex hospital discharges with a conventional organisation. Effectiveness will be assessed by reducing the length of stay of patients in geriatric short-stay care.
