The investigator aims to examine the clinical utility of WES, including assessment of a variety of clinical outcomes in undiagnosed pediatric cases.
Alzheimer's disease, stroke and TBI are frequently observed brain disorders, causing significant morbidity. For none of these disorders, there are in vivo diagnostic biomarkers available that allow determination of disease burden, patient-specific prognosis and therapy follow-up. However, they all share a similar mechanism that may cause accumulation of tau oligomers in the brain, synaptic dysfunction and cognitive and/or behavioral impairment. Until recently, the only way to quantify synaptic density and tau deposition was using post-mortem immunohistochemistry. Now, in vivo Positron Emission Tomography (PET) imaging of synaptic density has become possible trough development of 11C-UCB-J, a levetiracetam-based radioligand, expressing high affinity and specificity for SV2A. Furthermore, the novel radioligand 18F-MK-6240, specifically targeting tau deposits, was clinically implemented in our center. Through PET-MR, we can visualize the cascade of tau deposition, synaptic loss and degeneration of grey and white matter and relate these pathologic features to cognitive and behavioral deterioration. The goal of the study is to: 1) measure tau deposition and loss of synaptic density in these conditions as a potential measure for disease load 2) determination of the mid-term (2 years) monitoring capacity of combined functional-structural PET-MR imaging 3) relate progression of the imaging markers to cognitive and/or behavioral decline and 4) determination of the optimal combination of PET-MR metrics for early identification and risk-stratification of cognitive and/or behavioral dysfunction in de novo patients.
Background. Several nutritional factors have been evaluated as prognostic factors for survival in ALS patients at earlier stages of the disease [body mass index (BMI), body composition expressed as fat free mass (FFM), fat mass (FM), phase angle (PhA), low-density lipoprotein/high-density lipoprotein (LDL/HDL) ratio, cholesterol levels], while only two studies have evaluated some of these parameters after PEG placement. Aim. BMI and cholesterol levels were evaluated as prognostic factors for survival after percutaneous endoscopic gastrostomy (PEG) placement Moreover, the relationship between body composition and BMI in a subgroup of ALS patients was evaluated.
Resting-state functional magnetic resonance imaging (RS-fMRI) has frequently been used to investigate local spontaneous brain activity in Parkinson's disease (PD) in a whole-brain, voxel-wise manner. To quantitatively integrate these studies, we conducted a coordinate-based meta-analysis on 15 studies that used amplitude of low frequency fluctuation (ALFF) and 11 studies that used regional homogeneity (ReHo). All these ALFF and ReHo studies have compared PD patients with healthy controls. We also performed a validation RS-fMRI study of ALFF and ReHo in a frequency-dependent manner for a novel dataset consisting of PD and healthy controls.
The coverage of the caregivers of patients reached of neurodegenerative disease becomes essential. The psychic, physical but also social impacts for the caregivers are widely documented in the literature just like the stress associated with this role, we speak then about "burden of the caregivers". It seems that the caregivers set up little effective strategies of adaptation pulling fatal consequences on their well-being. He was shown in the literature, that a level of high stress is going to engender a decrease of mental flexibility and so entrainer a rigidity of adaptation. To decrease the burden of the caregivers, numerous interventions were proposed. The analysis of the literature highlights that these interventions are rarely developed from theoretical models pulling(entailing) a stream of techniques proposed to the caregivers but without precise objective. The most effective interventions concerning the coverage(care) of the burden of the caregivers are the ones which are targeted and structured, those who put the helper in active position and who have an effect on the subjective burden. The cognitive-behavioral therapy (TCC) would seem particularly effective. So, to modify the perception (collection) of the caregivers in front of cognitive, behavioral, functional modifications of their close friend(relation), to bring them to estimate positively their role and to favor the employment(use) of adaptive strategies turns out to be a privileged target of intervention to be used(employed) to improve the well-being of the caregivers and so decrease their burden. Considering this, an intervention based on the techniques of resolution of problems (TRP) could show itself very relevant as specific coverage (care). The works concerning the contribution of the TRP and the adaptation generally concerning situations of health showed that this type(chap) of intervention facilitated an adapted situational coping, but also increased generally the social, academic and professional performances. Various searches(researches) also showed that the resolution of problem is associated with indicators of adaptation at patients' nursing reached(affected) by Alzheimer's disease. So we propose to the family caregivers a coverage(care) based on the therapy of resolution of problems taking support on the model of Lazarus's stress and Folkman and according to the model stemming from works of D' Zurilla and Nezu. We make the hypothesis that this intervention is going to allow a decrease of the burden by allowing the caregivers to find a capacity to modulate their strategies to fit at best the evolutions of the clinical situation. The main objective of our study is to compare the efficiency of a coverage(care) based on the Therapy of Resolution of Problems to a group of word and to that proposed at the moment within the pole of gerontology in the decrease of the burden of the caregivers of patients reached(affected) by neurodegenerative disease in 12 months. Our secondary objectives will concern the evolution of the burden in 6 months and the evolution of the strategies of coping, the anxious, depressive symptomatology, the quality of life, the mental flexibility in 6 and 12 months. According to the data of the current literature, we expect a decrease of the psychological distress, an increase of the good(property) to be psychological. More specifically, by proposing an intervention targeted in particular at the management of the stress, the helper is going to acquire fitnesses which will have a long-lasting(sustainable) therapeutic effect. By associating techniques of psychoeducation with techniques of management of the stress we hope we can propose a type(chap) of intervention suited to the natural caregivers to favor the preservation at home.
NSHDS (Northern Sweden Health and Disease Study) is an umbrella term for a prospective biobank with related survey data. The sample collection consists of three subcohorts, Västerbotten Intervention Programme (VIP), Mammography Screening Project (MA) and MONICA (MONItoring of Trends and Determinants in CArdiovascular Disease). The blood samples are stored at the Northern Sweden Biobank.
To test the hypothesis that GLP1 can exert favourable effects on multiple aspects of brain function. To this purpose, the investigator determine whether chronic increase in GLP1 concentration as it occurs after bariatric surgery (Roux-en- Y Gastric Bypass) is associated with improvement in: - cognitive function measured by Mini Mental State Examination (MMSE) and Mental Deterioration Battery(MDB). - brain glucose metabolism measured by FDG-CT/PET - neuroplasticity measure by binocular rivalry and saccadic adaptation tests in morbid obese subjects. In order to discern the effect of GLP1 irrespective of changes in the metabolic milieu the investigator will test whether short-term GLP-1 infusion can modulate the same parameters in healthy subjects.
Performance assessment of the PMD-200, a novel pain monitor, in subjects with degenerative lumbar spine disease who requires surgical procedure
Sectorisation of the German health care system causes inefficient treatment, especially in elderly with cognitive impairments. At time of transition from hospitals into primary care it lacks, among others, coordination of post-operative care or timely communication between healthcare providers. This results in deterioration of disease and comorbidities, higher rates of re-admission and institutionalizations. Models of collaborative care have shown their efficacy in primary care. Main goal is to test the effectiveness of Dementia Care Management (DCM) for people with cognitive impairment to improve treatment and care across the in-hospital and primary care sector. The study design is a complex, longitudinal, multisite randomized controlled trial. It was designed to treat a hospital-based epidemiological cohort of people above the age of 70 with an adaption of DCM, a treatment proven to be effective in primary care, to the discharge setting. As part of this, specifically trained study staff will develop, implement and monitor a treatment and care plan, based on comprehensive assessments during the hospital stay, recommendations at discharge and unmet needs at home. For the 3 months after discharge study staff will coordinate treatment and care in close cooperation with the discharging hospital, treating physician and other care providers. Expected results from the study should facilitate the implementation of intersectoral care management systematically on a large scale. Thus, the benefits shown in the trial would be available to a larger population. Results will not be limited to PCI, but rather to any people transitioning between the in-hospital and the primary care sector. Thus, the benefits would be available to elderly people in general.
