Filter by:By detecting platelet antibodies of participants and then further to identify their genotype and analyzing laboratory examination, the investigators will obtain positive frequency of HPA antibodies, the distribution of HPA antigen and antibodies, effect of matching platelet transfusion, all of which in favor of draw a conclusion that it is very important to carry out HPA antibody detection and matching transfusion in early phase.

This is a Phase II study for the use of T-cell replete reduced intensity conditioning (RIC) haploidentical donor allogeneic hematopoietic cell transplantation (HaploHCT) for individuals with high-risk non-malignant diseases who lack a suitable HLA-matched sibling donor.
APACCHE (Adapted Physical Activity and Cardiac Coherence in HEmatologic patients) study investigates effects of heart rate variability biofeedback training, combined with classical adapted physical activity, on health-related quality of life in patients previously treated for hematologic malignancies. It is a prospective, randomized clinical trial from University Hospital of Reunion Island. The main objective is evaluated with QLQ-C30 survey score differences.

Scientific context Epstein-Barr virus has a causal role in the pathogenesis of multiple distinct lymphomas. Post-transplant lymphoproliferative diseases (PTLD) are the most frequent EBV-induced proliferations. PTLD after allogeneic stem cell transplantation has an incidence lower than 5% but may increase up to 10-20% in patients with established risk factors. EBV-DNAemia is predictive of EBV-PTLD and is routinely performed using qPCR on whole blood. Preemptive therapeutic strategies with anti-CD20 antibody are used when patients are above a defined EBV-DNAemia threshold. This approach remains limited since it does not discriminate between an EBV-induced lymphoproliferation (latent cycle) and/or a replicating virus (replicative cycle). Epigenetic modifications plays a central role in regulating the switch from latent to lytic gene expression. Specific DNA modifications can be regarded as molecular signatures for EBV genomes associated with the status of the viral infection (latent vs lytic). Accordingly, these signatures may be envisioned as a potent tool to characterize the state of the viral infection in vivo. Description of the project Our primary objective is to estimate the respective percentages of EBV-lytic and EBV-latent genomes (proliferating cells) in patients presenting with a high EBV-DNAemia after allogeneic stem cell transplantation HSCT by analysing the epigenetic modifications of EBV genome on specific sites. Our secondary objectives are i) to determine risk factors associated with each "latent versus lytic EBV" profiles and ii) to correlate the "latent versus lytic EBV" profiles with response to rituximab infusion and patient outcomes. For this purpose, a retrospective study (n=80) and a prospective study (estimation n=58) will be established. The different steps of this project are: 1. To study epigenetic modifications. The laboratory is developing a new approach to distinguish between latent and lytic genomes. 2. To realize quantitative analysis by RT-PCR of different EBV transcripts specific of the latent or of the lytic phase of the virus This method will be applied on RNA extracted from patient blood samples with elevated EBV viral load, under condition preserving RNA integrity. The results will be validated on a prospective cohort of HSCT patients (n=58) (Saint-Antoine Hospital and La Pitié-Salpêtrière Hospital). 3. To perform quantitative analysis of EBV genomes in plasma, saliva and total blood samples by current routine procedures In addition to total blood samples, plasma and saliva will be collected since free viral particles are known to accumulate in these biological fluids upon EBV reactivation. These samples will be treated by normalized procedures that are routinely used in the medical virology laboratory to quantify EBV in human samples. Expected results By establishing a simple method for studying epigenetic modifications of EBV genomes, we expect to understand the significance of high EBV viral load and the pathophysiology of post-HSCT PTLD. We aim to distinguish between the latent / lytic profiles of HSCT patients and to correlate their respective risks for developing PTLD. Establishing the epigenetic EBV profile in the post-HSCT setting when facing increase viral load and PTLD will improve our understanding of the biological mechanisms determining EBV-status in post-HSCT. This should improve major medical and economical issues. These results could have a major therapeutic
The Transition Navigator Trial (TNT) is a pragmatic randomized controlled trial evaluating the effectiveness of usual care plus a patient navigator service versus usual care plus newsletters and other educational materials, to improve transition outcomes among adolescents aged 16-21 who have chronic health conditions requiring transfer to adult specialty care. The study will provide urgently needed data to guide health care providers and policy makers regarding the provision of coordinated transition care. These results have the potential to: 1. Change care delivery 2. Improve health outcomes 3. Improve the experiences of young adult transition to adult care

To quantify the diagnostic, prognostic and therapeutic value of spectrometric analysis of exhaled breath from hematological patients with respiratory infection.
Sometimes, certain patients, while the treatment comes to an end and while a remission is possible, present psychological and emotional difficulties. The return in a " new life " is lived as a factor of often unexpected stress which force the patients, from the end of the treatment, to reconsider their future orientation, their roles and social identities, their interpersonal relations, and the quality of their life. Often, they feel a strong feeling of isolation and a shape of social marginalization stressed by the fact that forgiveness lead automatically to a spacing of the stays to the hospital, which were for them a source of social interactions. Often incapable to deal with these negative emotional situations, they live profound depressive episodes known to be associated to a lesser survival. The investigators think that a support of type onco-coaching of sport- inspirated could allow these survivors to find a certain quality of life to see certain well-being. In a recent study, It was analyzed the leadership " which works " in the high-level sport in France. Five selectors of national teams of team sports were questioned about their conceptions on the best practices of management and management of the people. They grant a quite particular attention on the individual consideration of the athlete and the implementation of a relationship of trust, to the delegation of the power and the sharing regulated by the decision-making which strengthen the sportsman in a feeling of autonomy and skill, catalysts of an intrinsic motivation. These needs were satisfied, they give meaning to the share and get a psychological well-being. The satisfaction of these needs is generally made through the realization of purposes, results wished by an action, which can sometimes enter in contradiction with the satisfaction of the fundamental needs and thus damage the well-being. The role of the coach is to help the coached to target its purposes, to decide on a strategy to affect him and keep an intact motivation throughout the process. Without being therapeutic, the questioning and the action of the coach would allow the coached to reach gradually the satisfaction of its fundamental psychological needs and thus a real well-being. The intention is to make them benefit knowledge and expertise in the field of the coaching and by a logic of research inter disciplinary to set up steps of support individualized to propose adapted answers and assist them at best in their company on returning to the life by making a significant contribution with the patients to help them to find of the autonomy in their own decision-making, to find their social identity (refusal and discharge of positive or negative discrimination), to accompany the therapeutic education of the patient towards a stake in social reeducation and finally, to highlight and to strengthen its interests and social concerns. In terms of public health, this approach, facilitating the transition of the treatment in the complete remission, could be subjected and so improve the quality of the services of support proposed until then. If the hypotheses of research see each other confirmed, this device coaching of sport-inspired of the patients in remission could then be transferable in other oncologic fields.
