Filter by:Endocrine therapy (ET) is widely used to treat hormone receptor positive breast cancer and prevent recurrence by downregulating estrogen function. However, ETs readily cross the blood brain barrier and interfere with the action of estrogen in the brain. Estrogen supports cognition and menopausal status is closely linked to cognitive health in women. This has raised concern that anti-estrogen ETs may affect cognition and brain health in breast cancer survivors. However, evidence across existing studies is inconsistent and these effects remain poorly understood. The incomplete understanding of the effects of ET are likely due to limitations of earlier studies - namely, the under-appreciation of the role of menopausal status and insensitivity of standard cognitive measures. This research project will address these earlier limitations by specifically comparing ET effects by menopausal status, and using highly sensitive, task-related functional magnetic resonance imaging (fMRI) measures to assess the effects of ET on brain function.
This study will assess cognitive function in patients with a primary brain tumour treated with radiation therapy (RT) to generate radio-sensitivity and volume effect parameters for the development of cognitive dysfunction. All types of brain tumours apart from glioblastoma will be included.
As complementary and alternative medicines in both Chinese and Western populations, Wu Qin Xi (the Five Animal Play) and Ba Duan Jin (the Eight Pieces of Brocade) have demonstrated small to medium effects on the improvement of various physical, cognitive, and quality of life measures. The purpose of this proposed study is to develop a culturally tailored, low-cost exercise program, "Function Improvement Exercises for Older Sedentary Community-Dwelling Latino Residents (FE-SaLiR)", to improve physical and cognitive functions and quality of life in older Latino adults in a non-clinical community setting. This will be the first study to combine Wu Qin Xi and Ba Duan Jin in non-Chinese population. The study has three specific aims: 1. Following the community-based participatory research model (CBPR), the research team, community health advocates and senior program participants will co-adapt Wu Qin Xi and Ba Duan Jin and co-design the content and delivery form of FE-SaLiR (Phase 1). 2. To conduct a three-arm pragmatic controlled trial to test the feasibility and acceptability of FE-SaLiR in older sedentary community-dwelling Latino residents (Phase 2). 3. To generate the estimates of effect size and retention from the pilot study data that will be used to conduct the power estimation of a large RCT that will compare the effectiveness of FE-SaLiR with other types of exercises in an NIH RO1 grant application. FE-SaLiR Phase 1 was delivered from August 2019 to November 2019. FE-SaLiR Phase 2 started recruiting participants by invitation in January 2020; the exercise program started in February 2020.
The purpose of this community-engaged project is to examine how taking part in different arts (dance & music), compared to control (no arts) affects older adults' Health-Related Quality of Life (HRQoL using the Short Form-20(SF) form), physical performance (Short Physical Performance Battery-SPPB), cognition (using the Montreal Cognitive Assessment-MoCA), social engagement (National Social Life, Health, & Aging Project-NSHAP survey), and perceptions of self (focus interviews).
This study aims to investigate the incidence and characteristics of cognitive Impairment(CI) in the elderly patients with acute coronary syndrome (ACS), and to determine whether CI are predictive of the prognosis of major adverse cardiovascular events (MACE) and mortality.
Age-related vision impairment and dementia both become more prevalent with increasing age. Research into the mechanisms of these conditions has proposed that some of their causes (e.g., macular degeneration/glaucoma and Alzheimer's disease) could be symptoms of an underlying common cause, or may be equally linked to a multifactorial context in frailty and aging. Research into sensory-cognitive aging has provided preliminary data that sensory decline may be linked to the progression of dementia through the concept of sensory deprivation. Preliminary data in hearing loss rehabilitation support the idea that improved hearing may have a beneficial effect on cognitive functioning; however, there are to date no data available to examine whether low vision rehabilitation, specifically for reading, could have an equally protective or beneficial effect on cognitive health. The present proposal aims to fill this gap.
Approximately 75% of cancer survivors experience some degree of cognitive deficit throughout their cancer experience, with upwards of one third of breast cancer survivors reporting impairments up to a decade after treatment. Chemotherapy and adjuvant therapy to remove cancerous tissue can result in deficits in attention, speed of processing, memory, and quality of life. Physical activity has been associated with a number of health benefits for breast cancer survivors including improvements in cognitive function. The investigators recently reported on the beneficial effects of acute exercise, or single sessions of physical activity, on processing speed and spatial working memory in breast cancer survivors, suggesting that acute bouts of physical activity may mitigate select domains of CRCI. Specifically, survivors in this study demonstrated faster processing speed, and trended towards faster and more accurate spatial working memory, after thirty minutes of moderate-intensity walking compared to seated rest. But half an hour of walking may be challenging to certain subgroups of survivors, particularly those who are deconditioned or with significant barriers to longer walks. With a renewed focus on un-bouted physical activity and avoiding inactivity during survivorship, it is important to better understand the dose or volume of exercise responsible for providing breast cancer survivors with the greatest cognitive benefits. The investigators examined the effects of varying durations of exercise (e.g., 10, 20 and 30 minutes) on cognitive function in breast cancer survivors to identify the optimal length of acute exercise. Findings from this study will inform new guidelines for acute exercise after cancer.
Sustained military operations (SUSOPs) result in psychological stress and cognitive dysfunction, which may be related to the recruitment of classical monocytes into the brain. Goals: - To investigate the effect of sustained-release beta-alanine on changes in cognition and markers of immune cell recruitment during a 24-hour simulated military operation. - To examine associations between changes cognition and changes in markers mediating immune cell recruitment.
The specific aims of this study are: Aim 1. Develop a staged and modifiable dyadic oral care intervention to provide functionally-tailored oral care rehabilitation for community-dwelling persons with dementia (PWD) and need-based skills training their family caregivers (CGs). Based on the literature review and MCWB, a 4-week intervention with 8 modules, including universal modules (e.g., environmental changes), CG modules (e.g., cuing strategies) and modules for both PWD and CGs (e.g., oral care techniques), will be developed addressing the relevant SCT constructs (e.g., functional deficits of PWD and caregiving needs of CGs). Guided by a validated, widely-used theory of rehabilitation medicine, modules will be used alone or in combination to provide personalized, hand-on, functionally-tailored oral care rehabilitation for PWD along with skills training for CGs to match their caregiving needs. The training focus shifts from the PWD to the CG, as the independence of the PWD decreases. Semi-structured interviews with family CGs will then be conducted (until data saturation is reached) to understand their oral care needs, desired intervention approaches, and the perceived feasibility and utility of the intervention. The intervention will be revised and then pilot tested with 4 dyads, one per each of the four functional levels of the DAT. Aim 2. Evaluate the feasibility and efficacy of the intervention in home settings through a randomized, controlled trial with 40 pairs of PWD and their primary CGs, including immediate post-intervention and 3-month follow-up. Dyads will be stratified into 4 functional levels based on the PWD's DAT score and then randomly assigned to the intervention or control (non-tailored usual care) group.
The aim of this study is to assess the use of ASPECTS and stroke biomarkers to predict the outcome and cognitive impairment in acute ischemic stroke.
