Filter by:The objective of this observational clinical study is to evaluate the variations in ascorbic acid during the transplantation phases and how these variations influence the oxidative status and patient outcome. The main questions it aims to answer are: - how many patients arrive at the transplant in a state of hypovitaminosis C? - how does hypovitaminosis C affect the patient's oxidative status? - how does hypovitaminosis C affect the length of stay in intensive care and post-transplant complications?
Wellness is defined as the active pursuit of activities, choices and lifestyles that lead to a state of overall health. Prehabilitation, or using rehabilitation in the period before surgery, can improve the pre, during, and post operative experience for the patient. Although exercise as prehabilitation has been well established in organ transplant, the investigators believe a multiphase approach will help to better serve patients and support patient wellness in the long-term. Supporting wellness behaviour change, such as exercise, stress reduction, and sleep, is associated with improved quality of life (QoL), mood, and improvements in well-being. Including behaviour change support in an exercise program can help support transplant patients in long-term positive lifestyle changes. The Transplant Wellness Program (TWP) is an exercise behaviour change program that includes additional wellness components such as nutrition, stress reduction, and sleep programs to support overall health and QoL of transplant patients. Specifically, the TWP will implement physical activity and behaviour change support for patients pre- and post-transplant surgery, addressing functional (frailty, indices of fitness, physical activity levels) and mental (anxiety, stress) outcomes to improve overall QoL. The TWP includes a 12-week exercise program that is delivered either pre-transplant or post-transplant, depending on length of time from study enrollment to transplant surgery. In addition to the exercise intervention, the TWP includes maintenance resources (access to group exercise classes, wellness webinars, group wellness coaching etc.), and wellness behaviour change support. The goal of the TWP is to improve outcomes of participants throughout their transplant journey, as well as reduce health services use. Collected outcomes will include program reach, effectiveness measures such as changes in physical fitness, adoption by healthcare practitioners, implementation of the program, and maintenance. In addition, will also collect health care use measures as the investigators believe the TWP will result in the reduction of several health care use outcomes, such as the number of hospital admissions (including intensive care unit admissions), length of hospital stays and emergency room utilization.
It has been reported that non-pharmacological methods can be used as an alternative in addition to pharmacological methods to reduce pain, anxiety, stress and inflammatory response that begins with the surgical incision in the intraoperative period and continues throughout the operation. It has been reported that music can be used as an alternative non-pharmacological method to reduce pain and anxiety in the perioperative period, as well as surgical stress and the related stress response. The aim of this study is to test the hypothesis that music used as a non-pharmacological method in the intraoperative period can reduce inflammatory response in living donor hepatectomy.
Allogeneic hematopoietic stem cell transplantation (allo-HSC) is currently one of the only curative treatments for haematological malignancies with a poor prognosis, the realization of which presupposes the identification and availability of a compatible donor. In recent years, haploidentical transplants have been developed, a reliable alternative for patients who do not have 100% compatible donors. The development of haplo-identical transplants leads to an exponential increase in the use of intra-family donation. Intrafamilial donation of hematopoietic stem cells (HSC) has the advantages of lower financial cost and faster availability of the graft, thus avoiding the risk of relapse before the procedure. Nevertheless, intrafamilial donation raises clinical and ethical questions. Indeed, the psychological impact of intra-family donation on the donor cannot be overlooked. Thus, in the context of the development of haplo-identical transplants, measuring the impact of donation on donors (ascendants and descendants) will make it possible to assess the relevance of taking psychosocial aspects into consideration in the choice of donors, to assess the psychological impact of haplo-identical donation and to offer psychological support adapted to donors.
This is a multicenter, randomized controlled, prospective clinical trial. The objective is to investigate the efficacy and safety of Tislelizumab maintenance therapy in newly diagnosed diffuse large B-cell lymphoma (DLBCL) patients after autologous hematopoietic stem cell transplantation (ASCT).
Allotransplants of vascularized composite tissues are subject to chronic vascular rejection, which can lead to graft loss. Currently, no imaging technique allows a reproducible quantitative exploration of the arterial trees of the hand, and therefore a satisfactory monitoring of transplants. Since 2014, flow MRI has been applied to the analysis of small-calibre arteries by the Image Processing Team at the Amiens-Picardie University Hospital. Between 2015 and 2017, several acquisitions were made in 3 patients who received facial allotransplantation, and the team recently developed a flow MRI protocol dedicated to the study of arterial trees in the hand. The main objective is to measure vascular flows of radial, ulnar and interdigital arterial trees in normal (healthy volunteers) and pathological situations (patients with radial forearm flap reconstruction and patients with hand allotransplantation) using the specifically developed flow MRI protocol.
The analysis of a cohort of consecutive non-selected patients from the Strasbourg University Hospital, and therefore representative of the real life, will allow better identifying the risk factors for these infections (by comparison with a cohort of patient with similar conditions of immunosuppression and no infection) and improving the diagnosis and therapeutic management. The primary objective is to identify prognosis factors affecting survival in patients with opportunistic infections
Reperfusion of renal graft in kidney transplantation can change the pharmacokinetic-pharmacodynamic (PKPD) parameters of rocuronium. The immediate increase of urine output during surgery may change the PKPD parameters of the drugs, including elimination rate. The goal of this study is to characterize the PKPD model of rocuronium during kidney transplantation and establish a basis for adequate dosage of rocuronium in kidney transplantation. Through PKPD modeling, the changes during reperfusion of the renal graft will be evaluated. Furthermore, the factors related to the changes will be assessed. Adjusting the infusion rate according to the step of kidney transplantation will lead to stable muscle relaxation and fast recovery.
Hepatitis E virus (HEV) is an emerging disease. The genotype 1 and 2 are predominant in Asia and Africa, and are responsible for recurrent epidemics. Genotype 3 is the main genotype found in Europe and North America and is responsible for sporadic infections except for travel associated diseases. HEV had a principally asymptomatic form. However, it was recently demonstrated that it could lead to a chronic form, especially in immunosuppressed patients. Moreover, in liver transplanted patients the infection could mimic a rejection and lead to the loss of the transplant. In other immunosuppressed patients, chronic hepatitis lead to cirrhosis and its well-known complications (ascitis, digestive hemorrhage, liver failure...). There is a lack of information about the prevalence of this disease. In Canada the incidence of HEV infection was high (15-86% for liver transplanted children with liver tests disturbed). In Germany the prevalence was lower: 3,2% in liver & kidney transplanted children whereas 7,4% in control. It was shown in a retrospective study that in liver (and liver+kidney) transplanted children the prevalence in Lyon was around 8,3%. This study will determined in a prospective approach the HEV prevalence in kidney, lung, heart and bone marrow transplanted children in Lyon.
This study aims to use tissue from deceased organ donors to investigate organ physiology, developmental biology, as well as the development of future regenerative cellular therapies. It will investigate function and immune response to stem cells as well as their generation from adult cells and generation of induced pluripotent stem cells (iPSCs).
