Filter by:Hematological neoplasms originate from the differentiation and proliferation of abnormal lymphatic or myeloid cells that alter the constitution of elements of the blood, bone marrow and lymph nodes. Treatment includes high-dose chemotherapy alone or associated with hematopoietic stem cell transplantation (HSCT). However, the adverse effects of this treatment affect multiple organs and systems, reducing physical capacity, increasing the feeling of fatigue, anxiety and depression, which together affect quality of life. Patients who exercise before, during or after anti-neoplastic treatment demonstrate significant benefits. But rehabilitating physical capacity involves the challenge of fluctuations in the patient's readiness along with daily clinical variations, which ultimately directly affects the rate of adherence to exercises, impacting the effectiveness of the physical rehabilitation program. There is no specific individualization of muscular overload that takes into account such variability in pathophysiological, functional and psychological situations, but the cardiorespiratory response and muscular strength performance in the face of progressive overload can be measured with sufficient recovery periods to optimize the physiological adaptations promoted by muscular overload. regularly, even in patients undergoing antineoplastic treatment. Objective: To evaluate the adherence rate, operational feasibility, clinical/behavioral evolution and effectiveness of three different muscle overload models (aerobic, anaerobic and mixed) used for the physical rehabilitation of patients hospitalized for antineoplastic hematological treatment with HSCT
The goal of this clinical trial is to compare the quality of mesoangioblasts isolated from various patient groups suffering from muscle atrophy. This study includes cancer cachexia and muscle-impaired elderly and a control group of the same age. The quality will be defined on these following outcomes: - The number and distribution of the mesoangioblasts in a muscle biopsy to define if there are sufficient mesoangioblasts to start a culture. - The proliferation capacity to define if we can culture them the numbers required for systemic treatment. - The myogenic capacity to define if the mesoangioblasts are sufficiently capable to generate muscle fibres. Participants will: - Undergo a muscle biopsy (needle biopsy or rest material from surgery, ~50mg) - Donate blood (~20 ml) - Fill in SARC-F questionnaire (evaluate sarcopenia score) - Fill in SQUASH questionnaire (evaluate physical activity of previous week) Researchers will compare groups (muscle-impaired elderly vs control; cancer cachexia vs control) to see if there is a difference regarding quality. These results will define the potential of autologous mesoangioblast therapy within these groups.
The goal of this study is to pilot test an Electronic Health Mindfulness-based Music Therapy Intervention (eMBMT) intervention to improve health-related quality of life (HRQoL) and reduce symptom burden of patients undergoing allogeneic stem cell transplantation (allo-SCT).
Integrity of the corneal epithelium is the function of intact limbal stem cells. The reduction in the population of LSCs and their dysfunction result in abnormal corneal epithelialization and invasion of the corneal surface by the conjunctival epithelium with or without corneal neovascularization that is, limbal stem cell deficiency (LSCD). Different techniques have been developed to treat cases of limbal stem cell deficiency due to traumatic or congenital cases. Recent innovations developed to predict the early stages of stem cell deficiency. One of these methods is measurement of the central epithelial thickness as it was found that limbal stem cell deficiency causes reduction of the central epithelial thickness. The aim of this study is to study changes in the corneal epithelial thickness at different quadrants of the cornea to observe the exact time of epithelial stability following stem cell transplantation.
It is a randomized phase 3 study comparing two conditioning regimens in children with Acute Myeloid Leukemia, AML, undergoing allogenic stem cell transplantation. The primary aim is to investigate if a conditioning regimen containing one alkylator (Bu) combined with two antimetabolites (Clo and Flu) results in superior 2-year acute grade III to IV-free, chronic non-limited GvHD-free, relapse free survival than a conditioning regimen combining three alkylating agents (BuCyMel)
Hematopoietic stem cell transplantation is applied in the childhood age group for many reasons such as hematological malignancies, immune deficiencies, hemoglobinopathies, bone marrow failures and congenital metabolic diseases. The transplantation process, which requires a long hospitalization process, is an experience that causes anxiety for the child and the caregiver.
The purpose of this study is to estimate overall survival (OS) for participants treated with abatacept versus those not treated with abatacept prior to hematopoietic stem cell transplantation (HSCT). Participants were included if their donors were unrelated and had 1-allele mismatched human leukocyte antigen (HLA) status.
To assess the outcomes of NRM when administering pharmacologic pretransplant immunosuppression (PTIS) followed by pretransplant reduced toxicity conditioning (RTC) and an allogeneic stem cell transplant (allo-SCT) and post-transplant graft-versus-host disease prophylaxis based on post-transplant cyclophosphamide (PT-Cy) in patients with inherited blood disorders.
The occurrence of acute and/or chronic GVH (Graf Versus Host disease) for recipients undergoing HSCT (haematopoietic stem cell transplantation) with a geno-identical donor suggests the implication of other systems or genes than those involved in HLA (Human Leukocyte Antigen) compatibility. In kidney transplantation, it has been shown that the AMS (allogenomic mismatch score) is correlated with the probability of survival of the graft. This AMS reflects the degree of differences between the immunopeptidomes of the recipient and his donor as it is a continuous variable based on the number of nsSNP (non synonymous Single Nucletotide Polymorphism) between the donor and the recipient. Roughly, the exome of the donor is aligned to the exome of the recipient, allowing to count the number of variations that will generate a peptide present in the recipient but absent in in the donor. In this case, peptide presented by the recipient's cells is not part of the donor's immunopeptidome, leading to an activation of the donor's immunocompetent cells toward this antigen, i.e. to alloreactivity that may cause GVL (Graft Versus Leukemia) and/or GVH. This study aims to highlight significant correlations between the occurrence of acute and/or chronic GVH after haplo-identical stem cell transplantation and the AMS. This would allow to use the AMS as a predictive factor of acute or chronic GVH, which could be employed to select the best donor for one particular recipient and/or personalize the immunotherapies after transplantation
Through a mixed methods, quasi-experimental design, the study will first focus on developing a mobile health (mHealth) adherence application and evaluating usability and acceptability of the app among caregivers of children in the acute phase post-HSCT. The purpose of this project is to explore the feasibility and acceptability of a mHealth application through user testing and thematic content analysis.
