NCT ID: NCT04451759 Recruiting - Eating Disorders Clinical Trials

Exploration by UHF MRI of Hypothalamic Networks Associated to Feeding in Obesity and Anorexia

HYPOTHALNET
Start date: June 25, 2020
Phase: N/A
Study type: Interventional

Food intake is a motivated behaviour that consists of seeking, selecting and ingesting nutritional resources from the environment. Its main function is therefore, depending on these conditions, to ensure the supply, in adequate quantities, of the energy and biochemical substrates necessary for the proper functioning and need of the body. Thus, in addition to maintaining the body's fat mass level stable, dietary behaviour is part of the energy homeostasis system and is thus regulated and maintained by the central nervous system. Although diet regulation involves several brain regions, the way in which these different regions communicate with each other and influence each other to orchestrate appropriate eating behaviour is not yet fully characterized. Among the structures of this network, the hypothalamus, a small structure (less than 1 cm3 in humans) composed of several nuclei such as the lateral hypothalamus, the arched nucleus or the lateral tuberal nucleus plays a crucial role. The investigators propose to use ultra high field (7T) magnetic resonance imaging equiping the CEMEREM (CHU Timone, APHM, Marseille) to better characterize the role of this crucial small structure in food intake networks in order to better understand the impact of these structural and functional disorders observed in patients with anorexia nervosa and obesity compared to a control population without eating behaviour disorders.

NCT ID: NCT04451694 Recruiting - Covid-19 Clinical Trials

Nutritional Follow up After Hospital Discharge for Coronavirus Disease-19

NutriCoviDom
Start date: April 1, 2020
Phase:
Study type: Observational

Coronavirus infection is responsible for muscle wasting (sarcopenia), especially during prolonged stays in intensive care. Sarcopenia, in its functional aspect also seems major in patients hospitalized for this infection, in non-ICU unit. Weight loss also appears to be significant, despite a prevalence of overweight and obesity in severe forms. Undernutrition in the obese patient is also possible (undernourished obese and sarcopenia obesity). Anosmia and dysgeusia participate in undernutrition by reducing energy intake. The rehabilitation of these patients requires nutritional support (increased protein intake) associated with progressive retraining to physical activity. An early and proactive management procedure within Coronavirus disease-19 units has been implemented in conjunction with the Transversal Nutrition Unit (TNU). This nutritional care must be continued after discharge. Follow-up by teleconsultation or telephone consultation is put in place after the patient's discharge Primary Objective: Evaluation of nutritional status at the time of admission and discharge and home follow-up in outgoing patients from Coronavirus disease-19 Units Secondary objectives: Description of the evolution of food intake, diversity of food and coverage of needs Evaluation of the muscular strength of the wrist (by grip test in hospital) and on the arms and legs after return home (visual analog scale) Evolution of anosmia and dysgeusia (at the time of hospital admission, at the time of hospital discharge and at home) Level of physical training before infection (IPAQ) Description of the general state of health measured by the performance index - world health organization scale Description of nutritional prescriptions Description of the prevention measures and incidence of Inappropriate Refeeding Syndrome (IRS) Care needs assessments

NCT ID: NCT04451317 Completed - COVID-19 Clinical Trials

Physical Activity Following the Containment Period Imposed by the COVID-19 Pandemic in Patients

PhysiCOVID
Start date: June 12, 2020
Phase:
Study type: Observational

In the context of the containment imposed by the COVID-19 pandemic and taking into account the numerous restrictions imposed, the practice of physical and sports activities (PSA) could be reduced by general population and sports population. While the practice of regular physical activity (PA) is prescribed and widely recognized as effective for the management of many chronic conditions and that regular participation in sports (SA) reduces the risk of injury and cardiac accidents- vascular disease in sports subjects, the reduction in regular physical activity levels in the wake of the period of confinement is likely to induce a medical risk in connection with the resumption of PSA.

NCT ID: NCT04451278 Recruiting - Epilepsy Clinical Trials

RESting-state Functional MRI for Prediction of Post-surgical Prognosis In Pediatric Drug-Resistant Epilepsy

RESPIRE
Start date: October 30, 2020
Phase:
Study type: Observational

Resting-state functional MRI (r-fMRI) has emerged in recent years to analyze resting networks. It allows, without active participation of the patients, to identify and analyze the different functional brain networks. The analysis of r-fMRI can be done thanks to the graph theory, which is based on the based on the calculation of quantifiable parameters applied to the functional network studied, making it possible to assess its effectiveness. To the knowledge of the investigators, no study has used graph theory applied to r-fMRI data in order to obtain parameters useful for the useful parameters for the individual prognosis of children who have to be operation for drug-resistant lesional epilepsy.

NCT ID: NCT04451018 Recruiting - Renal Insufficiency Clinical Trials

Evaluation of Macro and Microcirculatory Arterial Condition of the Upper Limb in Insufficiently Renal Patients

SYSTOE-HAIDI
Start date: June 17, 2020
Phase:
Study type: Observational

Evaluation of macro and microcirculatory arterial condition of the upper limb in insufficiently renal patients Hand ischemia affects 1.6 to 8% of patients with arteriovenous fistula (FAV) of hemodialysis in the upper limb. The diagnostic and therapeutic stakes are major as it concerns the functional prognosis of the hand and, to a lesser extent, vascular access for hemodialysis. In some cases, the diagnosis of ischemic hemo-hijacking is evident, in other cases, the ischemic condition appears to be rather the result of uncompensated arteriatory of the upper limb or limbs. Echo-doppler exploration is usual for assessing vascular access but without validated formal criteria for arterial disease in the upper limbs, with fistula flow calculation and analysis of FAV hemodynamics. Compression manoeuvres on or under the FAV can also be performed. The pressures of the digital arteries are also indicated with non-consensual values found in the literature for the diagnosis of digital ischemia but with varying tools in terms of collection of measurements. The main objective of this study is to collate the characteristics of arterial condition of the upper limbs of medium or severe renal patients, medium- or short-term candidates for kidney dialysis. The data collected will match the data of the arterial echodoppler as well as measures of pressures doppler laser and plethysmography. Candidates for dialysis tend to be older and polyvascular. A better assessment of the vascular condition of their upper limbs, including the diagnosis of advanced arterial disease, could eventually guide the choice of type of dialysis (compared to an indication of FAV).

NCT ID: NCT04450953 Recruiting - Clinical trials for Patients With a Kidney Transplantation on Cyclosporine

The Effect of Eplerenone on the Evolution of Vasculopathy in Renal Transplant Patients.

EVATRAN
Start date: October 12, 2021
Phase: Phase 3
Study type: Interventional

Cardiovascular (CV) pathologies are the leading cause of death in kidney transplant patients.Arterial stiffness is a prognostic factor for CV mortality in kidney transplantation. Despite a reduced CV risk in transplant kidney patients in comparison to patients in dialysis, CV mortality among kidney transplant patients is much higher than the general population. After renal transplantation, the cardiac and vascular anomalies observed in chronic end-stage renal disease are partially improved because of restored normal kidney function and withdrawal from dialysis. However, patients are exposed to immunosuppressive drugs, in particular calcineurin inhibitors, which can be associated with vascular toxicity, either directly or by promoting the appearance of hypertension, diabetes, or dyslipidemia.The pathophysiology of arterial stiffness in kidney transplantation is complex and multifactorial. Calcineurin inhibitors are likely to play an important role in the persistence of increased arterial stiffness in transplant patients in whom renal function has been restored. Indeed, the discontinuation of anti-calcineurins in favour of other molecules .is associated with a decrease of arterial stiffness. Preclinical work has shown that the vascular toxicity of cyclosporine is mediated by activation of the mineralocorticoid receptor in smooth muscle cells. The involvement of the mineralocorticoid receptor in the onset of arterial stiffness is also well demonstrated in non-transplanted subjects. Blocking the mineralocorticoid receptor in patients under cyclosporine may reduce their arterial stiffness and in and consequently improve their CV prognosis. Studies have show a good safety in kidney transplant patients. This pilot study proposes to examine, for the first time, the impact of treatment with a mineralocorticoid receptor antagonist on the evolution of arterial stiffness in renal transplant patients on calcineurin inhibitors.
