As complementary and alternative medicines in both Chinese and Western populations, Wu Qin Xi (the Five Animal Play) and Ba Duan Jin (the Eight Pieces of Brocade) have demonstrated small to medium effects on the improvement of various physical, cognitive, and quality of life measures. The purpose of this proposed study is to develop a culturally tailored, low-cost exercise program, "Function Improvement Exercises for Older Sedentary Community-Dwelling Latino Residents (FE-SaLiR)", to improve physical and cognitive functions and quality of life in older Latino adults in a non-clinical community setting. This will be the first study to combine Wu Qin Xi and Ba Duan Jin in non-Chinese population. The study has three specific aims: 1. Following the community-based participatory research model (CBPR), the research team, community health advocates and senior program participants will co-adapt Wu Qin Xi and Ba Duan Jin and co-design the content and delivery form of FE-SaLiR (Phase 1). 2. To conduct a three-arm pragmatic controlled trial to test the feasibility and acceptability of FE-SaLiR in older sedentary community-dwelling Latino residents (Phase 2). 3. To generate the estimates of effect size and retention from the pilot study data that will be used to conduct the power estimation of a large RCT that will compare the effectiveness of FE-SaLiR with other types of exercises in an NIH RO1 grant application. FE-SaLiR Phase 1 was delivered from August 2019 to November 2019. FE-SaLiR Phase 2 started recruiting participants by invitation in January 2020; the exercise program started in February 2020.
Cognitive and mobility impairments are critical contributors to dementia and disability in older adults, and can be caused by neurodegenerative and neurovascular changes at the pre-frontal (PF) brain areas. In a previous technological project funded by ISCiii, the investigators adapted a non-invasive, point-of-care optical methods (fNRIS/fDCS technology) to study PF metabolism and blood flow activation during cognitive and motor tasks, in older adults with and without cognitive impairment. These methods are sensitive to change after physical exercise (PE) and after selectively and safely stimulating PF areas with electrical transcranial direct current stimulation (tCS). PE and tCS have shown benefits for cognition and mobility in the elderly, but their prolonged effect on PF hemodynamic activation has not been studied. Understanding the specific action of these interventions on the brain, and their clinical cognitive and motor impact, is key to fine-tune appropriate treatment strategies. The FRONT STAGE project aims to compare, through a 3 arms single-blind randomized clinical trial, the impact of a 10 weeks, 1 hour/week program of PE (arm 1) Vs PE+tCS (arm 2) and Vs a control group (arm 3, healthy aging sessions and control of cardiovascular risk factors). The PE program is already implemented in primary care, as part of another previous project of the investigators' research group. Outcomes will include the optical measurement of PF metabolism and blood flow and clinical measures of cognitive and physical function. Front STAGE project will recruit 93 older adults with cognitive impairment and slow gait, but without dementia or disability in the activities of daily living (N=31 per arm). They will receive a comprehensive geriatric assessment at baseline, together with the optical, cognitive and physical measures, and will be follow-up at 3 and 6 months. Weekly physical activity through accelerometry will be controlled in analyses. FRONT STAGE project centered on aging and the prevention of dementia and disability, will provide, translationally, more evidence to support and enlarge the clinical application of these interventions, and will contribute to foster further research in this field.
The investigators will conduct a study of brain positron emission tomography (PET) using 11C-PIB for the imaging of brain amyloid in 250 participants in the Multiethnic study of atherosclerosis (MESA) at Columbia University Irving Medical Center in New York City. Participants will be imaged only once with Pittsburgh Compound B (PIB) PET.
Endoscopic retrograde cholangiopancreatography (ERCP) is an interventional endoscopy procedure utilized in the therapeutic management of pancreatobiliary diseases including gallstones, bile duct strictures, leaks and infections, pancreatitis, and cancers of the bile duct or pancreas. ERCP is classified as a high risk procedure. Potential adverse events directly attributable to the technical aspects of ERCP include pancreatitis, hemorrhage, infection, and bowel wall perforation. Other potential adverse events of ERCP may be less apparent and/or unknown, such as risk of neurocognitive dysfunction. Overall, neurocognitive dysfunction after medical procedures impacts quality of life, functional disability, depression, and caregiver and societal burden. The prevalence of postoperative neurocognitive dysfunction and disability following interventional endoscopy procedures such as ERCP has not been reported. This prospective observational study is designed to assess the prevalence of cognitive impairment and functional disability after ERCP and endoscopic ultrasound (EUS) procedures in older patients, and to assess whether specific patient and/or procedural factors are associated with increased risk of adverse outcomes.
The researchers are trying to gather information and learn more about imaging tests in racially different people who are cognitively normal or have dementia.
