This pilot study aims to determine the impact of whey protein supplementation on brain antioxidant levels and to assess the effects of whey protein supplementation on physical function, body composition, and cognition in pre-frail older adults.
This study consists of three aims focused on examining the feasibility of adding the Geriatric Resources and Assessment for the Care of Elders (GRACE) model to structured Annual Wellness Visits (AWVs) to improve patient and caregiver outcomes and reduce hospitalizations in older adults with complex health needs. The objectives are to: 1. Co-design a community-centric implementation strategy for the AWVs vs AWVs + GRACE -augmented care (AWV GRACE) study arms 2. Develop a referral pathway and algorithm to optimize enrollment of eligible participants 3. Conduct a pilot clinical trial to assess the feasibility of the AWV GRACE intervention.
The goal of this clinical trial is to find out if taking a pill (oral sedation) works just as well as getting medicine through a vein (IV sedation) to help older adults feel relaxed during cataract surgery. We are also studying how these two methods affect recovery, especially thinking and memory after surgery, and how satisfied people are with their care. Participants in this study will be randomly assigned to receive either oral sedation (+ IV placebo) or IV sedation (+ oral placebo) before their cataract surgery. They will complete short surveys about their thinking and recovery before and after surgery, and will be contacted by phone after surgery to check on their recovery. The results of this study will help doctors understand if a simple pill can be a safe and effective alternative to IV sedation for cataract surgery.
Cluster-randomized trial assessing the impact of interventions on guideline-concordant prescribing in Emergency Departments (ED). The study compares the effectiveness of feedback messages about potentially inappropriate medications (PIMs) delivered by peer clinician prescribers or anonymous systems, compared to standard of care. The goal is to reduce PIM prescribing for older adults discharged from emergency departments.
This is a randomized, double-blind, placebo-controlled, two-arm crossover clinical trial evaluating the effects of a patented age-reversal therapy, EGA®, compared to conventional nicotinamide mononucleotide (NMN) supplementation. The study will assess safety and efficacy in improving exercise tolerance and modulating biomarkers of aging in healthy older adults. The primary outcome is cycle ergometry constant work rate (CWR) exercise tolerance, measured as time to fatigue. Secondary outcomes include changes in peak oxygen consumption (VO₂peak), critical power, anaerobic work capacity, lactate threshold, and NAD⁺ metabolite levels. EGA® is composed of three metabolomic compounds that are endogenous to humans. The formulation has been used in prior exploratory studies and real-world applications, which have helped inform the design of this current trial.
The purpose of this study is to find out how early time-restricted eating affects body rhythms and improves cardiometabolic health in older adults.
The investigators aim to use smart-home sensors and artificial intelligence (AI) to monitor and detect Alzheimer's Disease and Related Dementias (ADRD)-specific daily activities among older adults, with the goal of early symptom detection and personalized support. Dementia, which impacts memory and cognition, remains a global concern. In the United States, more than 6.7 million individuals aged 65 and older are living with ADRD, and projected annual healthcare costs are expected to reach $1 trillion by 2050. This underscores the need for deeper understanding and innovative support. To address the unique challenges associated with ADRD, such as cognitive decline, personalized strategies that promote independent well-being are essential. Smart-home sensors can support older adults with ADRD as they continue to live in their homes. These sensors provide real-time data on health and daily activities, offering insights into their daily lives. However, adoption of these technologies is low, and the practical application of AI remains limited. This highlights the need for further research to make these devices more accessible to this population. The investigators' aims include: Conducting focus groups with individuals with and without ADRD and their caregivers to identify daily activities that can be measured using in-home sensors; Collecting in-home sensor data from older adults with and without ADRD; and Using AI to develop a tool for recognizing daily activities. The integration of smart-home sensors with advanced data-analysis techniques holds significant potential for transforming the support and care provided to individuals with ADRD. Ultimately, the investigators' findings will contribute to improving the quality of life for affected individuals and alleviating the burden on caregivers and healthcare systems.
Older adults with Mild Cognitive Impairment (MCI) often show less brain activity in a specific range (8-13 Hz, known as alpha power) compared to healthy older adults. Those with lower alpha activity, especially in the front part of the brain, usually have problems with executive functions like planning and multitasking. Our research has shown that older adults with lower alpha power in these areas also struggle more with balance when they have to do two things at once (like standing and performing a cognitive task simultaneously). The investigators believe that increasing alpha power in older adults with MCI could improve their balance and executive function, helping them stay independent longer. In early studies, the investigators found that using transcranial alternating current stimulation (tACS) at 10 Hz on the front part of the brain can boost alpha power and balance immediately after a single session in older adults with MCI. The effect was stronger in those whose natural brain activity was close to the 10 Hz stimulation. Based on these findings, the investigators plan to conduct a pilot study with older adults aged 65-85 years with MCI. Participants will be randomly assigned to receive either real tACS or a sham (placebo) treatment. Our main hypothesis is that real tACS will improve balance when multitasking, and these improvements will last for 1 to 3 months after the treatment. The investigators also believe that tACS will enhance other aspects of executive function and mobility and that these improvements will be linked to increased alpha activity in the brain. Through this study, we aim to gather strong evidence that tailored tACS is a promising treatment to improve cognitive and motor functions and overall brain activity in older adults with MCI.
The purpose of this study is to look at safety, tolerability, and pharmacodynamic effects (i.e. how the study drug affects your body) of PF-07258669 in older participants ((60 years to \<90 years) including those at risk of malnutrition. The study medicine PF-07258669 is being developed for the treatment of unintended weight loss in older adults. People with this condition have decreased appetite and food intake, which is an important reason for poor nutrition and health results in people with unintended weight loss. This is approximately a 26-week-long study with 9 visits to the study doctor and 4 telehealth visits (ie. visits by phone call). The study will include * Screening period for up to 4 weeks * Pre-treatment period of 2 weeks * Treatment period of 16 weeks : study drug (PF-07258669 or matching placebo) * Follow-up period of 4 weeks The study requires answering questionnaires and use of digital devices at home to measure blood pressure and physical activity. The study team will monitor how each participant is doing during the study
The purpose of this research is to investigate the impact of acute pain, induced using an experimental pain paradigm of capsaicin paired with heat, on implicit locomotor learning and its retention in older adults.
