Aging Clinical Trials

The menopause transition is associated with increased risk for weight gain and a shift toward storing fat in the belly region, which may increase risk for cardiovascular disease and diabetes. The study will determine whether the stress hormone cortisol contributes to this shift. Read Less

Investigators are adapting the LIFT and REFLECT interventions for older adults living with HIV who have been exposed to childhood sexual abuse. Read Less

With advancing age, adults experience increasing speech understanding difficulties in challenging situations. Currently, speech-in-noise difficulties are rehabilitated by providing hearing aids. For older normal-hearing adults, however, hearing devices do not provide much benefit since these adults do not have decreased hearing sensitivity. The goal of the "Speech Perception and High Cognitive Demand" project is to evaluate the benefit of a new auditory-cognitive training paradigm. In the present study neural (as measured by pupillometry and magnetoencephalography) and behavioral changes of speech-in-noise perception from pretest to posttest will be examined in older adults (age 65 - 85 years) assigned to one of three training groups: 1) Active Control Group: sessions of watching informational videos, 2) Auditory Training Group: sessions of auditory training listening to one of two speakers in everyday scenarios (e.g., driving directions) and needing to recall what one speaker said in the previous sentence, and 3) Auditory-cognitive training group: identical to the auditory training group, except participants will be asked to remember information from two previous sentences. Changes in speech-in-noise perception will be examined for the three groups of older adults and gains will be compared to a control group of young, normal hearing adults (18-30 years) that is not part of the clinical trial and will not undergo any training.

The long-term goal of this pragmatic, cluster randomized study is to develop a sustainable program for healthcare systems to reduce fatal and nonfatal falls among high-risk older adults living independently in their communities. This study will examine how a medication care plan, grounded in established medication deprescribing and tapering frameworks, can be implemented in primary care clinics to reduce falls among older adults living in rural Iowa communities. The study is a collaboration between researchers and clinical pharmacists at the University of Iowa and a clinical team from the MercyOneSM Health Network, which is a non-academic healthcare system with significant reach into rural Iowa communities The study's specific goals are as followed: * Aim 1: Examine the effectiveness of a clinic-based, individualized medication care plan in reducing rates of all falls including medically treated falls (sub-aim 1a) and motor vehicle charges and crashes (sub-aim 1b) among older adults seen in rural primary care clinics. * Aim 2: Identify provider and patient factors that are associated with patient adherence to medication deprescribing and discontinuation recommendations. * Aim 3\*: Evaluate implementation of the medication care plan to understand its acceptability, usability and relevance among healthcare system administrators, clinics (clinic managers and clinical staff), providers (health coaches, pharmacists, prescribers) and patients. Note\*: Only Aims 1 and 2 (i.e., pertinent to the clinical trial) will be described in this clinicaltrials.gov study description. Intervention and control patients will participate in: * Baseline assessment * Quarterly follow-up assessments * Monthly falls tracking Additionally, Intervention participants will receive: • An individualized medication action plan to deprescribe medications that put them at high risk for a fall Researchers will compare intervention and control participants for changes in self-reported fall rates (primary outcome), EMR-indicated medically-treated falls (secondary outcome), traffic-related charges (secondary outcome), and motor vehicle crashes (secondary outcome).

Competitive sport increases risk for musculoskeletal injury (e.g., traumatic knee injury) and may position former athletes for early onset of chronic diseases, chronic pain, poor health-related quality of life, and disability. Quantifying function in former athletes with and without a prior injury and non-athlete controls is critical to understanding long-term health trajectories in athletes and informing potential interventional studies. One modifiable factor that may be associated with long-term health in athletes is physical activity patterns. The purpose of this study is to evaluate strength, function, physical activity, dietary patterns, and cardiometabolic health among current and former competitive athletes and in nonathlete controls to evaluate the impact of prior knee injury and sedentary behavior as two potential determinants of later poor health and reduced function.

Senior Companion Programs (SCP) facilitate partnerships between community volunteers and local homebound seniors. Seniors served by the SCP will be provided with a companion who will conduct weekly visits with them, help with meal preparation or deliveries, provide transportation, assist with simple housekeeping, and socialize with the client amongst other tasks. These services are directed towards helping the senior client continue living independently in their own home instead of moving into an assisted living or nursing home. The SCP model is being evaluated to determine the impact of the services on the client's overall well-being and independent living status. Read Less

The Atlas of Retinal Imaging in Alzheimer's (ARIAS) study is a 5-year study examining the natural history of retinal imaging biomarkers associated with disease risk, disease burden, and disease progression in Alzheimer's disease (AD). The objective of this project is to create a 'gold standard' reference database of structural anatomic and functional imaging of the retina, in order to enable the identification and development of both sensitive and reliable markers of AD risk and/or progression. Our ultimate goal is to develop a new screening protocol that identifies changes related to AD 10-20 years before AD is clinically visible. Read Less

The Georgetown University Memory Disorders Program, part of the Department of Neurology, is conducting pilot studies of the feasibility of various diagnostic tests for Alzheimer's disease, mild cognitive impairment and other neurodegenerative diseases. Further, this study is assessing longitudinal changes in biological, lifestyle, and cognitive assessment collection. The primary goal of this study is to examine the feasibility of biochemical assays, genetic testing, and cognitive and lifestyle assessments in the ante-mortem diagnosis of Alzheimer's disease, mild cognitive impairment and other neurodegenerative diseases. This research involves genetic and cognitive status testing but the findings will not be shared with research subjects. This will be accomplished ex vivo using blood, and/or cerebrospinal fluid (CSF) specimens from patients with a diagnosis of probable Alzheimer's disease, mild cognitive impairment, or other neurodegenerative diseases and from normal controls.
