Filter by:There is evidence that survivors of childhood cancer have a high prevalence of poor sleep, including symptoms of insomnia. Insomnia is highly comorbid and has been associated with impaired cognitive performance, a range of psychiatric disorders, cardiovascular disease, and reduced quality of life. However, we still lack knowledge about the direct impact of available internet-based insomnia treatment programs for survivors of childhood cancer experiencing insomnia, in addition to how improving insomnia symptoms impacts neurocognitive function and late health morbidities in this population. Therefore, in this study, we will utilize the resources available in the Childhood Cancer Survivor Study (CCSS) to use an accepted, established, efficacious internet-delivered CBTi insomnia treatment program and evaluate the efficacy of this program in adult survivors of childhood cancer. Positive results from this study and our use of an internet-based intervention are likely generalizable and be scalable to the large and geographically diverse population of childhood cancer survivors with chronic health conditions. Primary Objective To examine the efficacy of an eHealth intervention for improving symptoms of insomnia among adult survivors of childhood cancer. Secondary Objectives To examine the impact of an eHealth intervention for insomnia on the clinical severity of insomnia symptoms in adult survivors of childhood cancer. To determine whether treatment of insomnia symptoms will improve neurocognitive function in adult survivors of childhood cancer with both insomnia and neurocognitive impairment. To explore the mediating effects of improved neurocognitive function, emotional distress, and cardiovascular health on the association between insomnia symptoms and quality of life.
Neurocognitive impairment (NCI) is one of the serious complications of elderly HIV-infected patients. The destruction of intestinal mucosal barrier and imbalance of bacterial flora caused by aging and HIV infection may be an important factor promoting the occurrence of NCI. Therefore, it is important to understand changes in gut microbiota of HIV-infected patients with NCI. Higher dietary intake of the essential fatty acid docosahexaenoic (DHA) has been associated with better cognitive performance in several epidemiological studies. To date, data are limited showing that DHA administration leads to benefits for behavioral disorders by modulating gut microbiota composition; the few studies on this subject, mostly completed in animal models. Moreover，low levels of DHA have been found in HIV-infected patients. The effect of DHA supplementation on gut microbiota and NCI status of HIV-positive patients have not been evaluated yet. Investigators aim to implement a case-control study to identify the relationship between gut microbiota and NCI in HIV-infected patients. At the meantime, investigators aim to implement a randomized, double-blind, placebo-controlled clinical trial to assess DHA supplementation in HIV-infected patients with NCI for 16 weeks. The effect of DHA on gut microbiota and NCI were evaluated. Also, investigators aim to identify if the benefits for NCI of DHA caused by modulating gut microbiota composition and metabolites.
Randomized control pilot 12 week feeding trial to compare the preliminary effects of ketogenic diet (versus patient choice diet) on HIV-associated neurocognitive impairment. N = 20 (n = 10/10) randomized to diet condition. Pilot data necessary to evaluate the feasibility and determine initial data for primary outcomes in order to accurately determine needed sample size for larger clinical trial. Outcomes: 1) cognition (NIH Toolkit), 2) cardiometabolic markers (insulin glucose, insulin resistance, markers of inflammation), and 3) neural activity (as determined by functional MRI..
Background: - Human immunodeficiency virus (HIV) infection appears to cause problems with blood vessel function. These problems may add to some thinking and mood disorders found in people with HIV infection. Researchers want to evaluate HIV infected patients to see if blood vessel function contributes to thinking and mood disorders, such as early dementia and depression. To do so, they will compare study results between people with and people without HIV infection. Objectives: - To compare the thickness of blood vessel walls between people with and without HIV infection. - To study the relationship between blood vessel thickness and thinking and mood disorders. Eligibility: - Individuals between 25 and 55 years of age who have HIV infection. - Healthy individuals between 25 and 55 years of age. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. - Participants will have imaging studies of the brain and major blood vessels in the head and neck. - Participants will also have neuropsychological testing. These tests will look at memory, learning and thinking ability, attention, and mood. - Participants will have the option of coming back for repeat blood tests every six months and repeat imaging studies and neuropsychological tests every year, over 1- 4 years period.
This longitudinal project will investigate a common complaint of women who receive chemotherapy for breast cancer- cognitive difficulty. The relationships of fatigue, stress, and depression to cognitive difficulties will be examined. The findings should lead to interventions to decrease the effects of these problematic side effects.
1. This study will evaluate the association between changes in basic cognitive and behavioral functioning by the end of chemotherapy treatment, and the later development of higher order executive functions in pediatric acute lymphoblastic leukemia (ALL). 2. The association between acute treatment-related changes in brain integrity and subsequent brain maturation in long-term survivors of pediatric ALL will be evaluated. 3. The association between patterns of behavioral and executive dysfunction and brain maturation in long-term survivors of pediatric ALL will be examined. 4. The association between genetic polymorphisms in key enzyme pathways and higher order brain development in long-term survivors of pediatric ALL will be explored. 5. The associations between biologic and behavioral indices of fatigue/sleep and higher order brain development in long-term survivors of pediatric ALL will be explored.
RATIONALE: Gathering information about how often problems with neurocognitive functioning occur in patients with newly diagnosed upper aerodigestive tract cancers may help doctors learn more about the disease. PURPOSE: This clinical trial is studying neurocognitive functioning in patients with newly diagnosed upper aerodigestive tract cancers receiving treatment at Henry-Joyce Cancer Clinic.
