Filter by:RATIONALE: Giving chemotherapy, such as busulfan, fludarabine, and melphalan, before a donor umbilical cord blood stem cell transplant helps stop the growth of abnormal or cancer cells and prepares the patient's bone marrow for the stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well combination chemotherapy followed by a donor umbilical cord blood transplant works in treating infants with high-risk acute leukemia or myelodysplastic syndromes.
The purpose of the study is to assess the usefulness of high Frequency mid-QRS analysis in identifying the ischemic origin of patients presenting to the Emergency Room (ER)with Chest pain.
Parallel group double blind randomised in patients with first episode corticosteroid sensitive nephrotic syndrome comparing time to relapse and adverse effects associated with a longer tapering steroid regimen with standard regime

Idiopathic Hypereosinophilic Syndrome (secondary HES), defined as a peripheral blood eosinophilia greater than 1,500 cells/µL for longer than 6 months, absence of other apparent aetiologies for eosinophilia and with or without signs and symptoms of organ involvement, irrespective to expression of any of imatinib targets (c-Kit receptor, PDGFR, bcr-abl receptor) on bone marrow cells. 2. Familiar hypereosinophilia defined as a peripheral blood eosinophilia greater than 1,500 cells/µL for longer than 6 months, absence of other apparent aetiologies for eosinophilia and signs and symptoms of organ involvement, irrespective to expression of any of imatinib targets (c-Kit receptor, PDGFR, bcr-abl receptor) on bone marrow cells, and with a recognized or reported cases of hypereosinophilia in the patient's family. 3. Chronic myeloproliferative disorder, defined as chronic eosinophilic leukemia (CEL) with the presence of blasts (>10%) in the bone marrow (BM), or the presence of immature eosinophils in different tissues, or an aggressive clinical course or the presence of clonal cytogenetic anomalies. 4. Myeloproliferative disorder (MPD) with eosinophilia, eosinophilic leukemia or chronic myelomonocytic leukemia [myeloproliferative disorders/myelodysplastic syndromes (MPD/MDS)] with evidence of: - t(5;12)(q33;p13) by cytogenetic or fluorescent in situ hybridization (FISH) analysis, or - ETV6/TEL-PDGFRB fusion transcript by reverse transcription polymerase chain reaction (RT-PCR), or - PDGFRB disruption, assessed or suspected, by other translocations with additional partner genes (H4, HIP1, CEV14 and Rab5) 5, or - MPD/MDS who have constitutive activation of the gene for platelet-derived growth factor receptor beta (PDGFRB) 6 by point mutations
Primary Objectives: This a pilot project to determine the feasibility of the preemptive CD8+ depleted T-cell donor lymphocyte infusion (DLI) in: - Reducing the incidence of graft versus host disease (GVHD) based on standard classification of acute and chronic GVHD - Improving hte disease remission rate in comparison with our previous study results. Secondary Objectives: - To investigate the impact of CD8+ depleted T-cell DLI in hematopoietic chimerism, and immunologic recovery of transplant patients.
This is a study to assess whether memantine is effective and safe in preventing age related cognitive deterioration and dementia in people with Down's syndrome (DS) age 40 and over. The study will last for a year and it will include 180 people with Down's syndrome with and without dementia. Participants will be assessed on memory skills, attention and problem solving abilities. Quality of life and abilities for everyday living skills will also be regularly checked. Primary Aims Clinical: - To determine the clinical efficacy of memantine versus placebo in preventing cognitive decline in people with DS. - To compare the safety and tolerability of memantine versus placebo in people with Down’s syndrome (DS). Biochemical and pathological: - To examine the ability of memantine to alter markers of disease progression in DS patients. Secondary Aims Clinical: - To determine whether memantine has, as compared with placebo, a significant positive impact on: - level of independent functioning as measured by the carer-rated adaptive behavioural scale, (ABS) in adults with DS; - quality of life in adults with DS. Biochemical and pathological: - To investigate putative markers of memantine’s mechanism of action in peripheral samples from living patients with DS.
The objective of this trial is to show the therapeutic efficacy of the preventive pacing therapies of the Selection 9000 and Vitatron T70 DR pacemakers, dedicated to handle atrial fibrillation (AF). Two new algorithms (post-AF response and ventricular rate stabilization [VRS]) will be assessed in a combined pathway, compared to a control group. The efficacy of the overall available therapies to prevent AF and its symptoms will then be assessed also.
Diabetes is prevalent in schizophrenics and may be induced by antipsychotic treatments. Several retrospective studies have suggested that psychiatric patients exposed to atypical antipsychotics may be at a higher risk for developing diabetes and ketoacidosis. The association between these atypical antipsychotics and the onset of diabetes is further strengthened by observations of: 1. the time sequence between the initiation of antipsychotic treatment and the onset of diabetes; 2. remission after the discontinuation of medications; and 3. re-emergence of diabetes following the re-introduction of atypical antipsychotics. The treatment emergent diabetes, along with other metabolic disturbances, represents a serious issue in the use of atypical antipsychotics. Major current debates and unresolved research issues which are also the focus of this proposal, are: 1. schizophrenia per se, versus the use of antipsychotics, in triggering diabetes; 2. whether there are differences between "typicals" and "atypicals" in such an effect; 3. whether there are differences among different "atypicals"; 4. whether, and to what extent, treatment emergent diabetes may be associated with, or independent of, weight gain, which also often is associated with the use of antipsychotics; and 5. genetic and environmental risks in association with treatment emergent diabetes. The policy of some hospitals in Taiwan that discourages the use of atypical antipsychotics for new onset schizophrenia directs the investigators to a study design looking at the associated diabetes of both types of antipsychotics. Such a design may provide some hints to the unresolved research issues mentioned above. Meanwhile, a broader defined term, X-syndrome, or metabolic syndrome, is being used to describe the diabetic condition associated with antipsychotics. X-syndrome is a risky condition leading to cardiovascular diseases and diabetes, with insulin resistance as the major outcome, associated with two of the following conditions: truncal obesity (deposited in the thorax and abdomen, instead of the hips and thighs), high triglycerides, high low-density lipoprotein (LDL) cholesterol or hypertension. The proposed study will combine the phenotypes of diabetes and X-syndrome to explore the abnormal metabolism caused by antipsychotics, bridge important information gaps, and provide data contributing towards a better understanding of the risk and management of diabetes and X-syndrome associated with the use of antipsychotics. Three assessment tools, namely the Clinical Global Severity (Clinical Global Impressions - Severity) or the Positive and Negative Symptom Scale (PANNS), the Diabetes Risk Assessment (ADA) and the Life Style Survey, together with physical measurements, collect additional information for this study. Diabetes related biochemistry, including glucose, insulin, leptin, lipids and glycohemoglobin, will be measured to form a composite phenotype for further pharmacogenetic studies. Candidate genes involved in pancreatic beta cell insulin secretion will be examined in priority to see if they play a role in the development of the antipsychotics-induced diabetes.
The PROMISSE Study is an observational study of 700 pregnant patients, enrolled at nine major clinical centers. The purpose of the study is 1) to determine whether certain proteins (called complement split products) that can injure healthy organs can be used to predict poor pregnancy outcome in patients with systemic lupus erythematosus (SLE) and anti-phospholipid syndrome (APS), and/or 2) to determine whether elevated levels of circulating antiangiogenic factors predict pregnancy complications in patients with aPL antibodies and/or SLE.
The purpose of this study is to define the mechanism(s) through which Obstructive Sleep Apnea/Hypopnea (OSAH) promotes abnormal metabolic processes which characterize the metabolic syndrome. The investigators hypothesize that the sleep fragmentation and intermittent sleep hypoxia which occur in OSAH patients promote oxidative stress and inflammation which in turn lead to insulin resistance, dyslipidemia, abnormal vascular reactivity and other processes which are consistent with the metabolic syndrome.
