Filter by:Patients with lung cancer and brain metastases undergo HA-WBRT-SIB using image-guided radiotherapy, receiving a total dose of 30-36 Gy delivered in 18-20 fractions to the whole brain (CTV), while the dose to the GTV is boosted to 44 Gy-52 Gy in 18-20 fractions, five times a week. The optimal mean dose (Dmean) to the bilateral hippocampus should optimally be ≤ 8 Gy, with a mandatory maximum dose (Dmax) to the hippocampus not exceeding 10 Gy; the preferred Dmean to the hippocampus PRV should optimally be ≤ 9 Gy, while the mandatory Dmax to the hippocampus PRV should be ≤ 12 Gy. The HVLT-R immediate recall scores are obtained at baseline and 1, 3, and 6 months after treatment.
While previous studies focused on the motor system in the analysis of postural functions, recently many researchers have determined that the sensory-cognitive-motor network system is required to determine the correctness of an action. , stroke individuals, Alzheimer's patients, Parkinson's disease, individuals with multiple sclerosis were discussed. In line with these studies, we can say that posture is handled with cognitive skills in people whose physical performance has decreased. However, the relationship between cognitive skills and posture in individuals with high physical performance has been ignored. Understanding posture and cognitive mechanisms is important both for physiotherapists who deal with posture from the neurophysiological aspect and for those who work in the field of psychology who deal with cognitive skills with its psychosocial aspect. The aim of the study is to reveal the relationship between posture and cognitive skills evaluated using the Stroop Test in healthy athletes in early adolescence.
Dementia is a clinical disorder characterized by progressive and permanent loss of multiple cognitive functions, especially memory, at a level that affects activities of daily living. There is no pharmacologic treatment method that can change the prognosis in dementia. The methods used today are symptomatic and cause various side effects. For this reason, non-pharmacologic approaches are on the agenda in the treatment of dementia. Among these approaches, physical activity approaches such as symptomatic treatment or exercise come to the forefront due to their prognosis-slowing effects. There are also many studies showing that dementia is directly related to physical performance and frailty. Deterioration of physical performance, increased frailty, and decreased muscle strength create a vicious circle with the prognosis of dementia. In addition, patients with dementia have balance problems due to prolonged reaction time, cognitive impairment and physical problems, and the risk of falls increases. In order to prevent the risk of falls, exercise practices are of great importance. Although the effects of aerobic exercise on dementia have been examined many times in the literature, there are very few studies examining the effects of balance exercises and combined exercises. In addition, physical characteristics such as frailty and muscle weakness, which are very common in patients with dementia, have not been evaluated as a whole in studies on patients with dementia. Therefore, this study will be conducted to comparatively examine the effects of combined aerobic exercise and balance exercises on balance and falls, frailty, muscle strength, cognitive functions, and reaction time in patients with dementia.
The current study aims to investigate the cognitive effects of diet-induced blood glucose fluctuations on cognitive performance in healthy older adults over multiple days, taking advantage of the currently available techniques to continuously measure blood glucose levels and to assess cognitive performance in a real-life setting. In this fully decentralized study, subjects will undergo two times a three-day measurement period, where their blood glucose will be continuously measured by a minimally invasive sensor and where the cognitive performance is measured at multiple time points throughout a day using a short test battery administered on their mobile phone. In addition to receiving standardized breakfast and lunch meals, the subjects are administered a low-GI(Glycemic Index) or normal-GI(Glycemic Index) snack in the morning and afternoon.
The goal of this randomized, double-blind, parallel group interventional study is to evaluate the effect of ketone bodies on healthy older adults (65-85 y) during 5 days of bed rest. The main questions it aims to answer are: Does supplementation of ketone bodies prevent the typical decline in muscle protein synthesis, muscle size, muscle function, insulin sensitivity, and muscle mitochondrial function that occurs in response to bed rest? Researchers will compare ketone supplements (KET) to an energy matched control beverage (carbohydrates and fats) to see if the ketones can rescue the decline in muscle protein synthesis rates, muscle loss, muscle function, insulin sensitivity, and mitochondrial function due to 5 days of bed rest. This may positively impact the heath of older adults subjected to bed rest.
The study will test whether the consumption of a low versus a high glycemic index pre-bed drink influences sleep architecture, memory consolidation, nocturnal glucose metabolism, and mood.
VisionPure™ is a softgel dietary supplement containing fish oil, lutein, zeaxanthin, and vitamin D. The intent of the VisionPure product is to assist in maintaining eye and cognitive health while helping to provide protection against blue throughout the day. In this pilot trial, approximately 16 participants will be recruited and randomly assigned to experimental and placebo conditions. Participants will consume 1 serving (2 softgels) per day of their respective study condition for 60 days. Prior to and following the 60 day supplementation period, participants will undergo a series of optometry and cognitive examinations to quantify eye health and cognitive function outcomes.
The overarching goal for this project is to develop a service-learning program that provides students excellent hands on training and patients with an excellent service that advances their health and well-being. The aim of this study is to test the feasibility, acceptability and efficacy of an 8 week intervention on physical behaviors, cognitive function, and health outcomes compared to a control condition among sedentary, overweight and obese adults.
This study will assess the preliminary efficacy of a lifestyle intervention including low-carb/ketogenic diet and exercise, enhanced by self-monitoring through health technologies on weight and diabetes outcomes (Glucose, HbA1c) and diabetic complications (cognitive function, and renal function) in a 6-month randomized clinical trial in 60 overweight/obese adults with or without T2D. Renal function will be assessed via both traditional and novel biomarkers, including novel metabolites and mitochondrial function.
In this study, the investigators will investigate the cognitive effects of fenfluramine, a drug that directly stimulates the release of serotonin in the brain and positively modulates σ1 function. The investigators will use fenfluramine to assess the cognitive effects of modulating serotonin and σ1 function in healthy volunteers using a battery of cognitive tasks that measure learning and memory, executive functioning, reward processing, and emotional processing. The study design is double-blind, and participants will be randomised to either seven days of fenfluramine or placebo administration. All participants will attend two screening visits to assess eligibility. There are two main study visits; during the first, participants will undertake cognitive tasks and questionnaires before taking the initial study dose. One the second study visit, participants will once again complete these tasks and questionnaires after a week of fenfluramine/placebo administration.
