As a person ages, an incidence of mental distress such as depression and anxiety increases while the quality of life decreases. Singapore's population is aging rapidly and older adults may suffer from mental distress and deteriorated quality of life. Recent evidence suggests that good nutrition is essential for mental health and quality of life in older adults. Previous research reported that provision of nutrition education and cooking workshops to people with mental illness for 3 months achieved healthy dietary change and improved mental health. This proposed study aims to further assess the effect of comprehensive dietary counselling on dietary quality, cardio-metabolic, mental health, sleep quality, and quality of life through a 24-wk parallel intervention study in Singapore older adults. The investigators hypothesised that older adults who receive comprehensive dietary counselling will improve dietary quality, cardio-metabolic health, mental health, sleep quality, and quality of life when compared to older adults who do not receive comprehensive dietary counselling.
The primary aim of this research proposal is to examine whether this novel training program approach is capable to tackle excessive loss in muscle mass, function and contractile capacity with aging. Previous investigations have universally shown a dramatic loss in type II muscle fibers, while certain countermeasures in their follow-up studies were generally ineffective and limited to attenuate this phenomenon. Probably, they failed to meet recruitment threshold of larger motor units and subsequently innervate type II muscle fibers. Furthermore, previous investigations also failed to provide any data on specific blood markers that may provide additional insight into muscle fiber loss with aging. Muscle fibers type II play a crucial role in the human ability to produce as much as force as possible over a limited time-frame (e.g. 100-200 ms) to counteract unexpected perturbations during stair climbing for example and thus avoiding falls. Therefore, this data collection would be noteworthy in particular, especially for this population due to health-related outcomes and healthy aging process. Since age-related decline is accelerated already after short bouts of physical inactivity, with small recovery potential, any attempt to counteract age-related and disuse-related decline have high clinical significance. Based on the findings, data collected may aid in development of safety guidelines and protocols aimed at reducing health risks in this specific population. Importantly, in case the aforementioned hypotheses are confirmed, present findings may offer important information to the healthcare system, especially for reducing economic burden.
Our study is a randomized controlled study and the subjects included in the study will be divided into three groups as virtual reality training, biofeedback training, and conventional rehabilitation.
Background: The autonomic nervous system controls automatic body functions. Researchers want to improve the tests used to diagnose autonomic failure. Orthostatic hypertension is a drop in blood pressure when a person stands up. Researchers want to focus on this sign of autonomic failure. Objective: To improve testing for conditions that cause autonomic nervous system failure. Eligibility: People ages 18 and older in one of these categories: - Their blood pressure drops when they get up. - They have had a heart transplant or bilateral endoscopic thoracic sympathectomies or have had or will have renal sympathetic ablation Design: All participants will be screened with: - Medical history - Physical exam - Blood and urine tests Some participants will be screened with: - Heart and breathing tests - IV placement into an arm vein - Tilt table testing: Participants lie on a table that tilts while an IV is used to draw their blood. Participants may stay in the hospital for up to 1 week depending on their tests. Tests may include repeats of screening tests and: - Sweat testing: A drug is placed on the skin to cause sweating. Sensors on the skin measure moisture. - Lumbar puncture: A needle is inserted between the bones in the back to collect fluid. - MRI and PET/CT scan: Participants lie on a table that slides into a scanner. For the PET/CT, a small amount of a radioactive chemical will be injected with a small amount of a radioactive chemical. - Bladder catheter placement to collect urine - Skin biopsies: A punch tool removes a small skin sample. - Tests to see how the pupils react to light - Smelling tests - Thinking and memory tests - Questionnaires Participants may have a visit about 2 years later to repeat tests.

Assessment of ascending ramus cortical plate for reconstruction of atrophic maxillary ridges versus chin cortical plates (Randomized clinical trial)
To determine the efficacy of ablative carbon dioxide laser in the treatment of the signs and symptoms of vulvovaginal atrophy (VVA) or genitourinary syndrome of menopause (GSM) in women with breast cancer.
The purpose of this survey is to evaluate the long-term safety and efficacy of leuprorelin acetate injection kit 11.25 mg in patients with spinal and bulbar muscular atrophy (SBMA) in the routine clinical setting.
The aim of the study is to investigate the effect of exercise in form of whole-body electromyostimulation (WB-EMS) on early tumor-induced muscular dysfunction. It is anticipated to gain detailed knowledge about composition and metabolism of skeletal muscle cells, and single muscle fiber functionality. To determine key factors leading to impaired force generation and thus decreased muscle strength in cancer patients who are suspected to develop or already show early signs of tumor cachexia is crucial for the establishment of effective cancer treatment. Comparative analysis of skeletal muscle biopsies taken from the abdomen of patients during indicated surgeries will be conducted. The patients will be allocated to the following study groups: a) Study group 1: Patients without cancer, b) Study group 2: Patients with solid tumors who did not perform physical training and c) Study group 3: Patients with solid tumors who executed physical training in form of WB-EMS. The investigation can help to understand skeletal muscle physiology under exercise and to get a better insight into the effects of physical training on early-stage muscle atrophy, both on cellular and molecular level. Initially, it is planned to identify the inflammation and nutrition status of the patients, and to determine skeletal muscle strength. It is anticipated to explore muscle protein composition, particularly myosin to actin ratio and their interaction. Biochemical analysis and the examination of the cellular ultra-structure should enhance the knowledge about the key mechanisms controlling the contractile apparatus of single muscle fibers in order to determine the quality of muscle force. Taken together, these investigations will help to better understand muscle atrophy in advanced cancer patients, and might support the development of targeted anti-cachectic therapies, that can be applied already in early phases of the tumor disease to significantly improve the patients' prognosis and their quality of life.
