NCT ID: NCT05610228 Recruiting - CLL Clinical Trials

Study of the Metabolism in the Lymphatic Niche of CLL

Start date: November 7, 2018
Phase:
Study type: Observational

Chronic lymphoid leukemia (CLL) is the most common adult leukemia that is characterized by a malignant monoclonal accumulation of tumoral and quiescent B cells in the peripheral blood. In advanced stages of the disease (Binet stage C), this population invades the bone marrow (BM) and proliferate into the lymphoid organs that results in widespread adenopathy. Richter's transformation is a most aggressive serious complication of CLL (transformation of the disease into an aggressive lymphoma) detected based on TEP/CT (Positron Emission Tomography/ computerized tomography) that shows highly derived glucose consumption by cancer cells. Clinical data from CLL patients with disease acutisation showed hypermetabolic lymphadenopathy with high standardized uptake value (SUV) whereas there is low grade tracer uptake into BM. We supposed that the tumor microenvironment of the lymphatic niche promotes the proliferation and glycolytic activity of CLL cells which become particularly resistant to treatment. The development of an ex-vivo tumor model that reproduces the microenvironment of the lymph node niche appears essential to identify and validate new therapeutic targets because despite the therapeutic arsenal available some patients still relapse or are refractory to treatment. Our objectives are to i / Characterize this niche of resistance by the development of an ex-vivo tumor model and ii / Evaluate in-vitro the effectiveness of the association of current treatments (RFC, Ibrutinib or Venetoclax) with anti-metabolic therapies (inhibitors of glycolysis) Our lab is developing an ex-vivo models of the lymphatic niche in CLL based on co-cultures of leukemic cells from patients stimulated with CpG ODN and IL2 with primary human lymphatic fibroblasts (HLF) (EC 12PP15). This co-culture has never been described in the literature and allows us to study the lymphatic niche of CLL patients. Lymph node (LN) exploration in CLL requires invasive access and does not bring any additional information in initial diagnosis. Then, we validated our co-culture model using complementary approaches: increased viability, proliferation, and resistance to Ibrutinib, associated with increased production of anti-apoptotic proteins such as MCL1 and BCL2 after 48 hours of co-culture. Secondly, we studied the metabolism in this resistance niche. We find an increased production of lactate and an acute consumption of glucose, associated with a strong metabolic activation detected by SEAHORSE and by the production of glycolysis enzymes such as hexokinase 2. Our study constitutes an original project because it characterized the energy metabolism of the CLL lymphatic niche by developing an original ex-vivo model and enhanced our understanding of the contribution of the specific microenvironment in the dissociation of metabolic activity using SUV max in BM and lymphatic niche. Anti-metabolic therapies are efficient on co-culture CLL cells and could be an alternative for refractory or relapsed patients under current treatment.

NCT ID: NCT05609864 Completed - Drug Use Clinical Trials

Drug Wastage : Observational Study in the Operating Rooms of France

GAME-OvBLOC
Start date: April 6, 2023
Phase:
Study type: Observational

Environmental awareness is leading medical field to question its responsibility and possibilities for action. Drug residues can have a major environmental impact as per their bioaccumulation, toxicity and persistence characteristics, depending on where they are discarded. In France, drug residues should be disposed of by incineration, but in practice this is not systematic. Moreover, data on drug wastage in the operating rooms by anesthesia department are rare. The GAME-OvBLOC observational study aim to evaluate drug wastage in the operating rooms by anesthesia department in France and to propose ways of improving health care practices.

NCT ID: NCT05609487 Recruiting - Suicide, Attempted Clinical Trials

Evaluation of the Safety Plan to Prevent Suicidal Reiteration

PROTECT
Start date: September 25, 2023
Phase: N/A
Study type: Interventional

Each year, suicide is the cause of 8,580 deaths in France, it is the second leading cause of death among 15-24 year olds. People who have made a first suicide attempt are identified as being at greater risk of repeating a suicidal gesture, particularly in the first month following the gesture . At the same time, Brief Intervention Contact (BIC) is recognized as effective in reducing suicide deaths. A new brief intervention to prevent suicidal attempts has been developed in the United States by Santley & Brown (2012) the results of its effectiveness are very encouraging. Investigators hypothesise that the implementation of a safety plan by the emergency department for suicidal patients included in the Vigilans system leads to a greater reduction in the reiteration of suicidality at 6 months compared to the usual management. Our main objective is to evaluate the effectiveness of the implementation of a safety plan by the emergency department nurse before discharge from the emergency department in reducing suicidal reiteration at six months after the suicide attempt, for suicidal patients included in the Vigilans programe, compared with the Vigilans programe alone. Our secondary objectives are - Reduce the reiteration of the suicidal act at 1 month - Encourage engagement in care at 1 month and 6 months - Reduce the use of emergency departments at 1 month and 6 months due to a suicidal crisis - Decrease suicide mortality at 6 months To study the implementation of the intervention: - To measure the quality of completion, and the duration of completion of the safety plan at 1 month, and 6 months. - Assess the acceptability of the safety plan by emergency department nurses, and then by the vigilantes. - Assess the acceptability of the safety plan by patient

NCT ID: NCT05609474 Recruiting - Addiction Clinical Trials

Trajectories and Reactions of Users and Relatives Consulting French Youth Addiction Services

TRYAD
Start date: February 15, 2023
Phase:
Study type: Observational [Patient Registry]

In France, the "Consultations Jeunes Consommateurs" (CJC) are the services specialized in the reception of young people for addiction problems. There are more than 500 CJCs throughout France. Depending on the situation, the CJC develops an early intervention strategy aimed either at reducing the risk of developing an addiction or at accelerating entry into appropriate care. The CJCs also meet with family members or professionals who may also independently request help or advice. Set up by the State since 2004, the action of the CJCs has never been formally evaluated. Only descriptive studies, carried out by the French Observatory of Drugs and Drug Addiction (OFDT), have made it possible to better understand the profile of people who consult CJCs. However, no longitudinal study has yet been carried out to understand the factors associated with the overall evolution of users consulting CJCs, nor with the level of satisfaction of users and those around them. Such objectives are complex, due to the diversity of situations encountered in CJCs and the heterogeneity of the CJCs themselves.

NCT ID: NCT05609084 Recruiting - Epilepsy Clinical Trials

Intensive Preoperative Speech Rehabilitation in Drug-Resistant Temporal Epilepsy

REPREO
Start date: March 30, 2023
Phase: N/A
Study type: Interventional

Out of 30,000 new cases per year in France, 30% of epileptic patients are drug-resistant. Neurosurgery, which consists in resecting the epileptogenic zone, is the only chance of cure. In the case of temporal epilepsy of the language-dominant hemisphere (TLE), this procedure presents a high risk of increasing cognitive difficulties and may even be contraindicated for this reason alone. The difficulties found are impairments in lexical access (anomia) and verbal memory and affect more than 60% of patients . Preoperative cognitive rehabilitation could influence brain plasticity mechanisms but there are currently no recommendations on this topic. In this context, the investigators have developed a speech rehabilitation procedure specific to the needs of ELTPR patients. They rely on cognitive hypotheses explaining the disorders but also on models of rehabilitation-induced neural plasticity likely to improve cognitive reserve before surgery. The investigators hypothesize that preoperative cognitive language rehabilitation in ELTPR patients may decrease surgical risk and improve postoperative language prognosis. The primary objective is to demonstrate the protective efficacy of preoperative speech rehabilitation on language performance postoperatively.

NCT ID: NCT05608902 Completed - Clinical trials for Basal Cell Carcinoma

Structural Description of Skin Biopsies With Dynamic Full-field Optical Coherence Tomography on Suspected Basal Cell Carcinoma Lesions, a Pilot Study (DOCTOBA)

DOCTOBA
Start date: September 6, 2022
Phase:
Study type: Observational

Basal cell carcinoma (BCC) are the most frequent skin cancers. Their incidence is constantly increasing. BCC diagnosis is first clinically suspected and then confirmed following histological examination of either a skin biopsy or the excisional specimen. Surgery is the first-line treatment and some procedures (notably Mohs surgery) require extemporaneous histological analysis of the edges to ensure a complete excision. Such on-site histopathological examination can be time consuming and associated with decreased sensitivity. Skin imaging techniques have already been tested to overcome these limitations and seem promising. Although some of them - such as confocal microscopy - are already even used in vivo, there is to date no report of the use of full-field optical coherence tomography for the diagnosis of BCC. The DOCTOBA study intends to describe direct histopathological examination of fresh skin biopsy or excisional specimen with dynamic full-field optical coherence tomography.
