Cardiometabolic Consequences of the Loss of Ovarian Function

Start date: April 1, 2024
Phase: Phase 4
Study type: Interventional

The menopause transition is associated with a decrease in artery health and an increased risk for weight gain in storing fat in the stomach area which may increase the risk for heart disease. The purpose of this research is to study how the decrease in estrogen at menopause changes artery health and fat gain, and risk of disease in women as they age. The first aim in this study will determine whether short term and long term low estrogen levels in premenopausal women decreases artery function and whether this is related to an increase in fat in the stomach area. The second aim will determine whether the changes in artery health and body fat are related to changes in a pathway that breaks down an important amino acid called tryptophan. This pathway is thought to play a role in regulating the aging process. Therefore, the investigators will determine whether the decrease in artery health and the increase in body fat in the stomach region with low estrogen is related to changes in this pathway in the blood, in vascular cells and fat tissue. Because estrogen levels fluctuate in premenopausal women, the investigators will use an approach (intervention) that controls estrogen levels to address these aims. The investigators will use a medication that is typically used to treat endometriosis or uterine fibroids to lower estrogen levels and an estrogen patch to increase estrogen in some women. Some women will receive a patch that has no estrogen (called a placebo patch). The intervention period will be 20 weeks. The study will provide us with new knowledge on how low estrogen with menopause affects artery health and fat gain estrogen.

Evaluating Implementation and Impact of Choose to Move (Phase 5)

Start date: April 2024
Phase: N/A
Study type: Interventional

Choose to Move (CTM) is a 3-month, choice-based health-promoting program for low active older adults being scaled-up across British Columbia (BC), Canada. In Phase 5, the goal of CTM is to enhance physical activity, mobility and social connectedness in three target populations: South Asian older adults, older men, and older adults living in Northern BC. To do so, the investigators will support community-based seniors' services (CBSS) organizations through a readiness-building process so they can adapt CTM and deliver the program to these populations. This study has two main research questions: 1. How are adapted CTM programs delivered ('implementation outcomes') and what factors influence delivery ('implementation determinants')? 2. What is the impact of the adapted CTM programs on health outcomes of older adults?

NCT ID: NCT06243016 Not yet recruiting - Aging Clinical Trials

Breaking Sitting With High-intensity Interval Training for Brain Health

Start date: January 31, 2024
Phase: N/A
Study type: Interventional

This trial will examine whether interrupting 3.5 hours of sitting every 30 min with 6 min high intensity interval training (HIIT) breaks compared to light intensity interval training (LIIT) will improve brain health in cognitively normal older adults. This trial will test the feasibility of HIIT breaks to sitting. It will also address several important but unanswered questions: (1) Does interrupting sitting with short HIIT breaks improve frontoparietal function? (2) Can interrupting sitting with HIIT breaks improve cognitive functions?

NCT ID: NCT06239688 Not yet recruiting - Aging Clinical Trials

Evaluating a National Person-Centered Training Program to Strengthen the Dementia Care Workforce

Start date: May 1, 2024
Phase: N/A
Study type: Interventional

This project will compare two training models of an evidence-based online dementia care training program for direct care staff in assisted living to a waitlist control: 1) essentiALZ training and 2) essentiALZ training + Project ECHO. It will examine the extent to which each model is implemented and achieves its intended outcomes to improve staff knowledge and attitudes, change care practices, and improve the wellbeing of staff, residents, and residents' family members. Results will inform next steps in dementia care training for the assisted living (AL) and broader long-term care workforce. To examine these outcomes, data will be collected from AL staff and families over the course of 6 months. Staff will complete questionnaires and participate in interviews (as applicable) at baseline, post-training, 3-months, and 6-months. Families will participate in interviews at baseline, 3-months, and 6-months.

NCT ID: NCT06235840 Completed - Aging Clinical Trials

Compensatory Brain Activity in Older Adults.

Start date: November 29, 2018
Phase: N/A
Study type: Interventional

There are two important aspects in which the present project will allow to enrich our understanding of compensatory brain activity in older adults. First, in the studies that have been conducted so far the compensatory brain activity in older adults was investigated primarily with the use of the functional magnetic resonance (fMRI) or positon emission tomography (PET). In order to identify compensatory activity in our study we will use electroencephalographic markers (observable in EEG). It will allow to confirm the assumptions about compensatory brain activity relying on new data, as in EEG research the brain markers of the same cognitive processes are different from those used in fMRI and PET research. What is more, in the studies conducted so far brain activity in older adults was only registered and interpreted, whereas the present study additionally adds the training component. The aim of our study is to see if it is possible to influence the compensatory brain activity through cognitive functions training, relying on working memory training. Theoretically, such a training should optimize brain activity in older adults, namely evoke compensatory brain activity during difficult tasks in order to make them easier, whereas in the case of easy tasks it should lead to the disappearance of the need to trigger compensatory activity. This assumption will be verified in an experimental setting. The participants will be divided into six groups: two experimental (the groups of young and old adults), and by analogy two active control groups and two passive (no-contact) control groups. The experiment was designed in the following way: (1) All groups will be subjected to pre-test measurements that will be EEG registration during a cognitive task execution at different difficulty levels; (2) Experimental groups will undergo working memory training. Over the period of 4 weeks participants in the experimental groups will take part in 12 training sessions. In the active control groups instead of the n-back training the practice of tasks which do not involve working memory will be introduced. Participants of the passive control groups will be awaiting post-test (no-contact control); (3) In all groups post-test measurements will be administered analogically to the pre-test measurements in order to assess changes in cognitive tasks performance and related brain activity.

NCT ID: NCT06235294 Not yet recruiting - Infertility Clinical Trials

Effects of Resveratrol Supplementation on Oocyte Quality

Start date: September 2024
Phase: N/A
Study type: Interventional

The goal of this randomized, double-blind, placebo-controlled clinical trial is to verify if 3-month oral supplementation with resveratrol can enhance the oocyte quality in advanced maternal age women undergoing in vitro fertilization (IVF). Participants will take a daily capsule of resveratrol or placebo during the 3 months preceding their IVF treatment. They will then follow the same treatment protocol as non-participant patients.

NCT ID: NCT06229093 Recruiting - Aging Clinical Trials

Multimodal Musical Stimulation for Healthy Neurocognitive Aging

Start date: December 11, 2022
Phase: N/A
Study type: Interventional

This is a Stage I randomized, sham-controlled trial on the effects of multimodal musical stimulation on working memory in aging. Neurologically healthy older and younger adults will be tested on working memory and electroencephalography in the first randomized controlled trial of music as a form of brain stimulation, with multimodal musical stimulation and control stimulation conditions. Results will test the causal role of oscillatory mechanisms of the brain on cognition, and will lay the groundwork to the first musical, neurophysiologically targeted, brain-stimulation device for reversing cognitive decline in aging.

NCT ID: NCT06225648 Not yet recruiting - Healthy Clinical Trials

Threonine Requirement in Adults >60 Years of Age

Start date: January 30, 2024
Phase: N/A
Study type: Interventional

Threonine is an essential amino acid and must be obtained from the diet. The body's capacity to maintain adequate mucin synthesis is directly related to the bioavailability of certain amino acids, including threonine, serine and proline (1). Moreover, the rate of mucin synthesis has been demonstrated to be directly related to the availability of dietary threonine in healthy rats (2) and piglets (3,4). Intestinal inflammation is known to increase gastrointestinal threonine uptake and mucin synthesis in enterally fed minipigs (5). Additionally, in animals, mucin function/barrier has been shown to decline with age, leaving them more susceptible to bacterial penetration. Thus, with advancing age (6), a higher dietary supply of threonine may be needed for maintaining intestinal mucosal health. Despite this, the current threonine requirement is based on studies conducted exclusively in young adults. Thus, there is a need to determine the threonine requirement directly in older adults.
