Filter by:The purpose of this study is to evaluate the feasibility and effectiveness of acupuncture for the treatment of phantom limb syndrome in lower limb amputees and pilot an acupuncture protocol. The study will be a comparative effectiveness study comparing acupuncture and standard care versus standard care alone and will be a randomised controlled trial using a mixed methods approach. The study hypothesis is a course of acupuncture will reduce the symptoms of phantom limb syndrome in lower limb amputees. The study will be based the Amputee Rehabilitation Unit, London. Twenty lower limb amputees with phantom limb syndrome will be randomly assigned to either receive usual care or usual care plus acupuncture. Acupuncture intervention will include 8 treatments over 4 weeks and treatment will involve using both body and auricular acupuncture points. Usual care will include physiotherapy, occupational therapy, pharmacological intervention and other interventions as deemed appropriate by clinical staff. An eleven point numerical rating scale will be the primary outcome measure in this study. Secondary outcome measures will include the Short Form McGill Pain Questionnaire 2, EQ-5D-5L, Hospital Anxiety and Depression Scale, Perceived Stress Scale, Insomnia Severity Index, Participant Global Impression of Change and information will also be obtained on rescue medication. A cheek swab will also be taken to explore potential subgroups of responders in relation to the genetic polymorphism of the glucocorticoid receptor. Outcomes will be recorded weekly for the duration of the study and one and three months post completion of the study. In order to identify protocol acceptability and acceptability of outcome measures five participants will be interviewed post completion of the study. Data will also inform feasibility such as recruitment rate, completion rate and reasons for dropout. Data from this study will guide the development of a full randomised controlled trial.
The Boston Keratoprosthesis type I (KPro) is a prosthetic cornea used to treat several causes of corneal blindness. Some categories of patients, including those with auto-immune diseases such as Stevens-Johnson syndrome, toxic epidermal necrolysis syndrome and mucous membrane pemphigoid, have a higher risk of failure for the KPro. Because of chronic inflammation, the cornea supporting the KPro may melt, leading to a higher risk of infection, loss of the KPro and loss of the eye. Infliximab is an antibody against tumor necrosis factor alpha and is used intravenously to control inflammation in several diseases. It has been used in some cases of corneal melting with significant success. This study's hypothesis is that infliximab can be successfully used as an eye drop (instead of the usual administration through veins) and that its regular use may prevent melt in eyes with a Boston Keratoprosthesis type I and underlying auto-immune disease.
Phase II trial combining azacitidine with valproic acid as maintenance therapy post allogeneic stem cell transplantation in patients with high-risk MDS/AML. We hypothesize that adding valproic acid to azacitidine will improve outcomes via both direct anti-tumor and immunologically mediated antitumor response with alloreactive donor lymphocytes, having an additive effect and extending 1 year survival in patient with high-risk AML/MDS after hematopoietic stem cell transplant. Based on aforementioned data from the US Department of Health and Human Services, standard 1 year survival for AML after stem cell transplant is near 40%. We hypothesize that valproic acid and azacitidine will prolong survival, with a 1 year survival goal of 60%. In addition to assessing for 1 year survival, we will have secondary objectives of assessing progression-free survival, relapse, and toxicity. The primary toxicity endpoint from this will be cytopenias and infections.
A novel method has been developed to expand natural (NK) cells and enhance their cytotoxicity against cancer cells while maintaining low killing capacity against non-transformed cells. In this method, donor NK cells are expanded by co-culture with the irradiated K562 cell line modified to express membrane bound IL-15 and 41BB ligand (K562-mb15-41BBL). Expression of these proteins in conjunction with unknown stimuli provided by K562 cells promotes selective growth of NK cells. Then, the expanded NK cell population is depleted of T cells to prevent graft versus host disease (GVHD). Expanded and activated NK cells showed powerful anti-leukemic activity against acute myeloid leukemia (AML) cells in vitro and in animal models of leukemia.Unpublished laboratory results also demonstrated that T-cell acute lymphoblastic leukaemia (T-ALL) is extremely sensitive to the cytotoxicity exerted by the expanded and activated NK cells. The present study represents the translation of the laboratory findings into clinical application. The study proposes to determine the feasibility, safety and efficacy of infusing expanded NK cells into patients who have AML or T-lineage ALL which is resistant to standard therapy as demonstrated by persistent minimal residual disease (MRD). Patients with myelodysplastic syndrome (MDS), who are at high risk to develop AML will also be eligible for the study. In this patient cohort, the study will also investigate the in vivo lifespan and phenotype of the expanded NK cells. The main hypothesis to be tested in this study is that infusion of expanded activated NK cells can produce measurable clinical responses in patients with AML or T-ALL.
Pentoxyfylline therapy in addition to the standard of care of albumin, midodrine and octreotide therapy is superior to the standard of care alone in the treatment of Type I hepatorenal syndrome in the first 14 days of hospitalization.
The investigators previous research has suggested that lipid (fatty) composition in the muscle cells of mice plays a key role in their insulin sensitivity. The purpose of this study is to determine whether these specific fat signatures translate to humans by comparing the muscle of healthy patients to those with pre-diabetes, or "the metabolic syndrome".
Adults with abdominal obesity are at high risk for cardiovascular disease and also exhibit diminished growth hormone (GH) secretion; the latter further contributes to the development of visceral adiposity, impaired fibrinolysis and inflammation.Growth hormone releasing hormone (GHRH), the primary stimulus for endogenous GH secretion, is a substrate of dipeptidyl peptidase 4 (DPP4); inhibition of DPP4 with the currently available anti-diabetic therapy, sitagliptin, may therefore increase GH secretion by decreasing the degradation of GHRH. The proposed research will test the hypothesis that chronic sitagliptin therapy will enhance GH secretion and vascular function while improving glucose tolerance in patients with impaired GH secretion who are at risk for the development of diabetes mellitus and cardiovascular disease, specifically obese women with polycystic ovary syndrome.
The investigators hypothesize that treatment of twin-twin transfusion syndrome (TTTS) using sequential laser photocoagulation of communicating vessels (SQLPCV) over the predominant method, selective laser photocoagulation of communicating vessels (SLPCV), may provide vascular stability to the donor fetus. The primary objective is to evaluate the perinatal outcome, specifically, donor intrauterine survival of TTTS managed by SQLPCV vs. SLPCV in a prospective, randomized trial.
This pilot clinical trial aims to assess feasibility and tolerability of using an LINAC based "organ-sparing marrow-targeted irradiation" to condition patients with high-risk hematological malignancies who are otherwise ineligible to undergo myeloablative Total body irradiation (TBI)-based conditioning prior to allogeneic stem cell transplant. The target patient populations are those with ALL, AML, MDS who are either elderly (>50 years of age) but healthy, or younger patients with worse medical comorbidities (HCT-Specific Comorbidity Index Score (HCT-CI) > 4). The goal is to have the patients benefit from potentially more efficacious myeloablative radiation based conditioning approach without the side effects associated with TBI.
This clinical trial studies decitabine and cytarabine in treating older patients with newly diagnosed acute myeloid leukemia, myelodysplastic syndrome that is likely to come back or spread to other places in the body, or myeloproliferative neoplasm. Drugs used in chemotherapy, such as decitabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving decitabine and cytarabine may work better than standard therapies in treating cancers of the bone marrow and blood cells, such as acute myeloid leukemia, myelodysplastic syndrome, or myeloproliferative neoplasm.
