Filter by:Normal aging is associated with a progressive decline in cognitive functions, especially memory. This decline in cognitive function can negatively impact the quality of life of older adults. Although there are currently few possibilities to prevent and/or slow the signs of cognitive decline, both those associated with age and neurodegenerative pathologies, one of the non-invasive brain stimulation techniques that has gained attention in recent years is Transcranial Direct Current Stimulation (tDCS). tDCS is a technique based on the application of a low-intensity (< 2 mA) direct electrical current between two large-area electrodes placed on various surface areas of the head. Moreover, according to safety-related meta-analyses it is a very safe technique, without any major side effects, provided that internationally established safety protocols are taken into account in its application. This technique has recently been investigated as a potential treatment for both healthy elderly people and people with mild cognitive impairment and Alzheimer's disease in several cognitive variables, having shown encouraging results in working memory learning curves, modulation of plasticity and recognition tasks. This project aims to implement an intervention using transcranial direct current stimulation in healthy older adults, MCI and AD. The main objective is to test if there is an improvement in cognitive efficiency and if the changes are maintained over time (1 month). For this purpose, the effect of the technique will be studied on participants assigned to treatment and control groups, analyzing the possible modifications in the following cognitive variables: cognitive plasticity and learning potential, recognition and familiarity and false alarms.
The demographics of the U.S. prison population are shifting at a dramatic rate requiring new approaches to prison healthcare. Current estimates suggest that there are 2.3 million incarcerated persons in the U.S. Similar to the free world, the aging of the Baby Boom generation is occurring in prisons. Notably, inmates 50 and older constitute over 20% of prisoners in state or federal facilities. From 1996-2016, there was an 280% growth in the number of state and federal prisoners age 55 or older, which is in sharp contrast to younger inmates that grew by only 3% during this time period. A surge in older adult offenders in the U.S. has not occurred but rather statutes now impose stiffer sentences, resulting in longer periods of incarceration, such as life without parole or 20+ years. At the same time, early release policies remain restrictive. As a result, sentenced offenders are living through middle and older adulthood within the confines of prisons.
The purpose of this Phase I open label study is to evaluate longer term tolerability and potential effectiveness of transcranial ultrasound in people with age-related frailty.
In a PCORI-funded project on HIV and aging engagement that was co-led by the study team, the topics of isolation and depressions were identified as priority areas of deep concern among older PLWH. The COVID-19 pandemic has enhanced the urgency to test interventions to mitigate depression and isolation among older PLWH. However, there is scant evidence on effective interventions that help mitigate depression and isolation among older PLWH. While physical distancing and stay at home orders are a necessary strategy to flatten the curve, ease pressure on the healthcare system, and protect the most vulnerable, the order further increases the isolation faced by people aging with HIV, and creates barriers to accessing medications, health services, and other resources. This project will include 6 virtual focus groups and 12 individual interviews with adults ages 50 or older in California (Palm Spring, Los Angeles) and the Tampa-Bay region, Florida to (1): further characterize issues related to depression, isolation, and basic needs of people aging with HIV during the COVID-19 pandemic (2) utilizing results from Aim 1, co-develop ideas for what to include in a virtual village, and (3) create and pilot the virtual village in a group of people aging with HIV. The overall goal of this study is to execute an innovative solution to address issues related to isolation for older PLWH which have been exacerbated during the COVID-19 pandemic.
The overall objective of this study is to investigate the efficacy of low-intensity blood flow restricted resistance exercise (BFRRE) to promote health beneficial skeletal muscle adaptations and augment muscle function in a healthy older population. This objective will be achieved by in-dept evaluation of skeletal muscle cellular and functional characteristics prior to and after an intervention period comprising 6 weeks of BFRRE or non-exercise control intervention in healthy older subjects. A special focus is placed on the ability of BFRRE to stimulate skeletal muscle protein synthesis and augment muscle stem cell function. Furthermore, recent findings suggests that similar exercise interventions in a population of patients with heart failure (HF) does not stimulate the desired adaptations. In accordance, we aim to compare the adaptive response to BFRRE amongst HF patients and the enrolled age-matched healthy individuals from the present investigation. The findings of the current study will expand our understanding of how low-intensity resistance exercise alternatives might be viable in promoting muscle anabolism to combat the loss of muscle mass observed with ageing as well as the potential anabolic resistance accompanying HF diagnosis.
This study is being performed to determine if a multi-ingredient dietary supplement is safe and easy to take by healthy older adults. Participants will be required to take one of three different doses of the dietary supplement for 90 consecutive days and complete wellness surveys and a daily log while taking the supplement. Participants will also provide blood samples at the start of the study, after 30 days, and at the end of the study which will help determine how participants respond to the supplement.
The goal of this study is to explore the effects of transcutaneous vagus nerve stimulation(tVNS) on improving cognition in community-dwelling elderly people. The study will recruit 120 subjects. Participants will undergo baseline cognitive assessment, EEG and eye tracking. Participants will be randomized to tVNS group and sham group. All subjects will repeat the baseline assessments after 1st session, 5th session，10th session and within 3 days after 10th session.
With increasing age and health issues associated with aging, many systemic cellular and structural changes are known to occur. The intent of this trial is to determine the safety and efficacy of delivery of autologous cellular stromal vascular fraction (cSVF) to improve the quality of life and functional health. Isolation and concentration of cSVF will be documented. To acquire autologous cSVF, a 10+ teaspoon volume of subdermal adipose (fat) tissue and stroma is removed from the trunk or upper thigh area. Using a closed system with enzymatic digestion to isolate and concentrate these cells, is followed with returning these cSVF elements only via 500 cc Normal Saline delivered via peripheral vein (IV). Documentation of cellular numbers and flow cytometer viability testing is to be correlated with clinical outcomes as reported by patients and standardized Quality of Life (QoL) form tracking
This is an intersectional and interdisciplinary screening program in Viborg Municipality, including 67 years old citizens. This observational study will estimate the cost-effectiveness of a combined screening program for the following conditions: Abdominal aortic aneurysm, peripheral arterial disease, carotid plaque, hypertension, arrhythmia, and type-2-diabetes. Furthermore, the incidence of the outlined conditions will be described and so will the result of the intervention initiated (secondary medical prophylaxis, smoking cessation, introduction to nutritionally deficient diet etc.)
Tendons are essential structures for transmitting muscle forces to skeletal structures. A stiffer tendon will transmit muscle force faster, and then allow faster movement. Moreover, tendons are a living tissue and respond to mechanical forces by changing their metabolism as well as their structural and mechanical properties. The aim of the present study is to answer essential questions remaining unanswered that are necessary in order to optimize physical activity with ageing in humans, and thus improve quality of life in elderly. The main questions are: What is the minimal training intensity leading to tendon adaptations? What is the time-course of tendon adaptations? Does the same loading protocol lead to similar tendon adaptations for different tendons (Achilles vs Patellar) and does the same training program lead to identical tendon adaptations with age (25yrs vs 75yrs)? To answer these questions, tendon architecture and mechanical properties will be investigated in humans of different age and applying different training intensities. The kinematic of the tendon adaptations due to these different training characteristics will also be investigated. The training protocol will be applied on plantar flexors and knee extensors. MRI and ultrasound techniques as well as the use of ankle and knee ergometers will allow the quantification of possible modifications in tendon architecture and mechanical properties (tendon stiffness and Young's Modulus). This will be assessed in vivo, using ultrasound images to assess tendon displacement during an incremental maximal contraction.
