NCT ID: NCT06064292 Completed - Aging Clinical Trials

Long Term Effects of Inspiratory Muscle Training in Cerebral Palsy

Start date: March 21, 2023
Phase: N/A
Study type: Interventional

Background: Respiratory disease is one of the main causes of morbidity and mortality in adults with cerebral palsy (CP). Adequate pulmonary function is essential to prevent these health problems, however respiratory muscle training has not yet been studied in CP patients. The main objective of the study was to investigate the maintenance over time of improvements in respiratory parameters achieved with inspiratory muscle training (IMT). Methods: This was a controlled, randomised, double-blind trial and with allocation concealment performed on 27 institutionalized CP patients randomly distributed in 2 groups, "high intensity training group" (HIT) and "low intensity training group" (LIT). Participants followed a specific IMT program for 8 weeks, HIT workload was 40% of maximum inspiratory pressure (MIP) and LIT workload was 20% MIP. Once finished 8-week training period, CP patients continued their daily activities. Respiratory muscle strength and pulmonary function were measured pre-IMT, post-IMT, 4, 12 and 24 weeks after finishing IMT.

NCT ID: NCT06058897 Recruiting - Aging Clinical Trials

MRI and Eye-tracking Predictive Markers of Cognitive Ageing

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

This research proposes to investigate physiological and cognitive markers of locus coeruleus (LC) neuronal integrity and function in cognitively-healthy participants over 60 years old. The locus coeruleus is a brainstem nucleus, sole source of noradrenaline for the brain. Tau pathology appears in neurons of this nucleus, which may induce initial cognitive changes. The study aims at relating locus coeruleus markers, assessed with MRI and eye-tracking techniques, with cognitive function.

Assessing Cognitive and Health Improvements in the Elderly Via Exercise (ACHIEVE) - Study.

Start date: January 11, 2024
Phase: N/A
Study type: Interventional

In Colombia, a demographic transition is occurring that is reflected in an inverted population pyramid, with an increase in the proportion of older adults due to a better quality of life, as well as a decrease in the young population due to the low birth rate. These changes pose challenges for the healthcare system due to aging and its negative consequences for the body. The rate of aging has increased fourfold since 1950, which means a significant increase in the population of older adults compared to those under 15 years of age. Although exercise has been proven to have positive effects on the physical and cognitive health of older adults, there are still gaps in the literature concerning cognitive impairment in older adults, and the optimal dose to achieve maximum therapeutic potential has not been determined. Therefore, the purpose of this research is to establish the optimal dose-response relationship to high-intensity exercise for improving cognition in older adults with mild cognitive impairment. A Randomized Controlled Clinical Trial with four groups will be conducted. One of the groups will serve as the control and will not receive treatment, focusing on occupational activities. The other three groups will be experimental, and the frequency and duration of exercise will be modified based on the World Health Organization (WHO) guidelines and a previous systematic research with meta-analysis. In the first experimental group (EG1), the WHO recommendations will be applied, consisting of 150 minutes of high-intensity exercise three times a week in sessions of 50 minutes each. In EG2, participants will perform high-intensity exercise twice a week, with a duration of 30 minutes per session. In EG3, high-intensity exercise will be performed four times per week in sessions of 50 minutes each. All experimental groups will receive high-intensity physical exercise interventions that combine aerobic and strength exercises adapted to the population. The sessions will be divided into three phases: warm-up, core phase, and cool-down. Different sociodemographic, cognitive, and physical condition variables will be evaluated. All dependent variables will be measured before and after the intervention, and statistical analysis will determine which exercise prescription yielded the best results in terms of cognitive improvement. This research aims to provide valuable information about the optimal dose of high-intensity exercise to improve cognition in older adults with mild cognitive impairment in Colombia."

TINO: T Cells in the Nose of Older Adults

TINO
Start date: January 24, 2021
Phase:
Study type: Observational

Rationale: Individuals with advanced age are at a progressively increasing risk of acquiring lower respiratory tract infections. Besides calendar age, the degree of frailty also associates with increased susceptibility to pneumonia requiring hospitalization. How alterations in the mucosal immune system with advanced age predispose to infections remains unclear as access to relevant tissue samples is limited. With minimally-invasive nasal sampling methods, it was recently observed that in vital older adults, both CD4+ T cells and CD8+ T cells are selectively lost from the nasal mucosa. However, the exact phenotype, underlying mechanisms, key molecules and consequences of this have not yet been investigated. Objective: Elucidate the mechanisms underlying the loss of nasal T cells and characterize in depth the differences of T cells in young and older adults and associate this loss with susceptibility to infections. Study design: Prospective cohort study Study population: Participants will be recruited from 3 groups: - healthy young adults (18-30 years, n=50) - vital older adults (>65 years, n=60) - frail elderly (>65 years, n=60). This group includes individuals without a history of recurrent respiratory infections or with >2 self-reported episodes of respiratory infection in the past year. Main study parameters/endpoints: Frequency of nasal CD8+ T cells in young adults and frail older adults. Secondary study parameters/endpoints: - Phenotype (subsets, activation status), functionality, transcriptomic state, clonality and frequency of nasal and blood T cell populations - Stability of T cells and other immune parameters, as described for main study parameter, during a second sample after 3 months. - Analysis of other immune populations as for main study parameter - Concentration of nasal and systemic factors (e.g. cytokines and metabolites) and their association with T cells and other immune populations - Respiratory tract microbiota profiles and presence of asymptomatic viral infections and their association with T cells and other immune parameters - Chronological and biological age, sex, and other immunologically relevant parameters with T cell populations and other immune parameters - Alteration of T cell phenotype, during and following respiratory tract infections. Levels of antigen-specific T cells and other immune parameters in nose and blood post infection.

Sequential Multiple Assessment Randomized Trial of Exercise for PAD: SMART Exercise for PAD (SMART PAD)

Start date: September 8, 2023
Phase: Phase 3
Study type: Interventional

Supervised exercise therapy (SET), consisting of treadmill exercise conducted three times weekly at a center while supervised by healthcare personnel, is first line therapy for people disabled by lower extremity peripheral artery disease (PAD). However, travelling three times/week to a center for SET is burdensome. Compared to SET, home-based exercise is more accessible and less burdensome. Yet, evidence-based guidelines recommend SET over home-based exercise for PAD. Walking exercise is first line therapy to improve walking distance for PAD, but it does not eliminate ischemic leg symptoms in most people with PAD. The investigators' work and that of others showed that nitrate-rich beetroot juice, which increases plasma nitrite, limb perfusion, and skeletal muscle function, significantly improved exercise tolerance and reduced non-response to exercise in people with and without PAD. The investigators will use a 2 x 2 factorial design to address two major barriers to achieving benefits from exercise therapy for PAD: First, guideline recommendations for supervised exercise therapy (SET) as first line therapy for PAD. Second, the inability of exercise therapy to eliminate PAD-related disability in most people with PAD. Participants will be randomized to one of four groups for 12 weeks: Supervised treadmill exercise + nitrate rich beetroot juice; supervised treadmill exercise + placebo, home-based walking exercise + nitrate rich beetroot juice, home-based walking exercise + placebo.

Influence of Overground Walking on Biomarkers, Cognitive Function, and Quality of Life in Elderly With Mild Cognitive Impairment

Start date: September 5, 2023
Phase: N/A
Study type: Interventional

The purpose of this research is to investigate the impact of overground walking as a part of a rehabilitation program on the increase in Brain-derived neurotrophic factor (BDNF) levels, decrease in IL-6 levels, decrease in hs-CRP levels, improvement in cognitive function, and enhancement of quality of life (QOL) in older people with mild cognitive impairment. These findings are anticipated to contribute to the efforts to elevate BDNF levels, cognitive function, and QOL while reducing IL-6 and hsCRP levels in the elderly with mild cognitive impairment.
