Filter by:IMPAACT 2015 is a cross-sectional, exploratory study that will investigate the central nervous system (CNS) reservoir in perinatally HIV-infected adolescents and young adults on effective antiretroviral therapy with neurocognitive impairment. The study will assess the frequency with which HIV is detected in the cerebral spinal fluid (CSF) in this population and assess whether detectable HIV in the CSF correlates with markers of inflammation and neuronal injury. Findings from this study will advance understanding of the role of the CNS in HIV-1 persistence and its implications for future HIV-1 remission research.
Diabetes has become important risk factors for threatening human life and health. Studies have shown that chronic hyperglycemia lead to microvascular brain injury. The more common types of dementia are Alzheimer's disease (AD). Cognitive dysfunction is a precursor to Alzheimer's disease. Mild cognitive impairment (MCI) is a cognitive impairment between normal aging and dementia, mainly manifested as memory impairment, especially episode memory defects, but also named obstacles, but the overall cognitive function is normal, daily life ability is normal. Studies have shown that middle-aged diabetic patients' cognitive ability will decline by about 19% in 20 years compared to people without diabetes. Sulfur amino acid is the indispensable amino acid in mammals, and its metabolites include Taurine, Hydrogen sulfide (H2S) and sulfur dioxide (SO2). Taurine was first isolated more than 150 years ago from ox (Taurus) bile. Although the taurine can be synthesized in vivo by cysteine in the presence of cysteine dioxygenase, it is mainly acquired from dietary sources, such as eggs, meat, and seafood. H2S is a biologically relevant mediator and plays potential roles in several physiological processes and disease states in the body. H2S is synthesized from 2 sulfur-containing amino acids, l-cysteine andl-methionine, by the 3 enzymes,cystathionine-γ-lyase (CSE), cystathionine-β-synthetase(CBS), and3-mercaptopyruvate sulfurtransferase (3-MST). Previous studies have demonstrated that Taurine and H2S may play important roles in the development of themicroangiopathy and lower extremity arterial occlusive.
Cognition encompasses memory, attention, language and other brain capacities that are necessary for good quality of life and independence. Age-related cognitive decline starts at the third decade of life and in some cases can start to impact daily functioning in the late forties. Dementia is the most devastating consequence associated with age-related cognitive decline. Recent studies indicate that improving cognition by means of intensive computerized brain training can mitigate some aspects of agerelated cognitive decline, and may even have a role in preventing or delaying dementia onset. Critically, the capacity of a given individual to improve their cognitive performance after training is fundamentally related to engagement with the exercises. Currently, little is known about how to apply intensive computerized cognitive training effectively in the health system, ensuring engagement and best progress. This project aims to tackle this challenge by developing, applying and testing personalized approaches to implement cognitive training in daily life of older adults that were recently evaluated at Memory Clinics and their care partners. The community readiness approach will be implemented using semi-structured interviews, conducted with subjects that may be interested in cognitive training, key informant, and key stakeholders. Using this information, the investigators will design an individualized training program and follow up its application in a feasibility trial. Twenty participants, recently evaluated at different Memory Clinics in Ireland, will be recruited, interviewed and invited to engage, over the ensuing 2 to 3 months, in computerized cognitive training. Subjects will be assessed after completion of the intervention for training adherence and individual gains on the computerized exercises. In order to gain insight about regional specificities of the approach the investigators will perform a parallel project using the same methodology in Brazil. This project is expected to inform the future implementation of cognitive training in public health policies for older adults.
The diagnostic and therapeutic progresses, associated with modifications in lifestyle and socio-cultural level of populations, have led to a remarkable increase in life expectancy. At the same time, the increasing medicalization of the individual has eroded the traditional boundaries between health and illness, normal and pathological state. This leads to the patient losing his sense of ownership of his own death. If most patients died at home before the Second World War, 75% of the population dies in hospital or institution at the present date. Most hospitals and care institutions have developed codes, in multidisciplinary internal consultation, to address the interruption or lack of implementation of treatments that make no sense from a medical point of vue. This avoids therapeutic relentlessness.The code in place within the CHU Brugmann is: - code A: no therapeutic restriction - code B: not to be resuscitated - code C: not to be intensively treated (no escalation in therapeutic treatments) - code D: best palliative care (progressive de-escalation in therapeutic treatments). These codes are established in consultation with the patient or his legal representative and are re-evaluated in a multidisciplinary way every week. Planning a care path and therefore establishing a therapeutic code is particularly important for people with cognitive impairment and dementia because the progressive loss of cognitive abilities complicates the process of decision making. A large part of the admissions are made via the emergency department. For these patients, no therapeutic plan has been established beforehand. However, the perception of the functional and cognitive status of the patient directly influences the intensity of care provided. Cognitive disorders are a risk factor for the exclusion of access to palliative care for the elderly patient. The objectives of this study are: - To establish a record of the therapeutic limitation codes in an acute cognitive geriatric unit - To correlate the therapeutic limitation code with the comorbidities of the patients
The purpose of this study is to investigate the effect of cognitive rehabilitation program on the improvement of cognitive functions in patients with mild cognitive impairment(MCI).
The Gerontology Research Programme (GRP) in the National University Singapore's Department of Psychological Medicine, was formed to coordinate and facilitate the conduct of multi-disciplinary research on in a wide range of research on ageing and health. The establishment of the Singapore Longitudinal Aging Cohort will provide a large community-based cohort of elderly subjects for observational studies with useful clinical applications. Research synergy is achieved in terms of pooling multi-disciplinary expertise, and combining genetic, biological, environmental, behavioural, social, clinical, and health services approaches to gerontological research.
The prevalence of older people with cognitive decline is increasing since the aging population is growing substantially worldwide. Cognitive impairment places older adults at high risk for functional disability. Previous researches have provided strong evidence on the beneficial effects of physical exercise on maintaining cognitive functions in older adults. Tai Chi is considered as a low to moderate intensity exercise, which is performed in a slow and rhythmic movement. It is a popular and safe exercise suitable for older people who have weaker muscle strength. The aim of this study was to determine the effects of Tai Chi on cognition and instrumental activities of daily living (I-ADLs), and health-related quality of life (HRQOL) in older Chinese adults with mild cognitive impairment (MCI). The research hypothesis of the study stated: There is significant improvement in the general cognitive performance, functional capabilities of instrumental ADLs,the physical component and mental component of HRQOL between the group of community-dwelling older people with MCI who have participated and the control group who have not participated in the Tai Chi program.
The objectives of the current project aim to determine whether a more controlled amplification method or a visual administration has an effect on hearing impaired older individuals' cognitive test scores.
The purpose of this study is to investigate whether preoperative pain is the risk factor of POCD in elder patients.
The current central dogma of long-term cognitive impairment after intensive care admission suggests an underlying neuroinflammatory dysregulation affecting neuronal function. This pathological process has not been fully elucidated and there has been little research into its genetic associations. Alzheimer's disease (AD) causes cognitive impairment through a process of abnormal beta amyloid deposition and neuronal death through localised activation of the innate immune system. It is the most prevalent disease affecting cognition. The Apolipoprotein E (APOE) gene is implicated in the progression of late-onset Alzheimer's disease and is a recognised neuroinflammatory modulator. It is possible that young individuals exposed to high levels of inflammation may experience an acceleration of this process. This study sets out to look for an association between APOE-∈4 possession and poor cognitive outcome after a major burn injury and intensive care admission.
