Interferon-α After DLI for the Prevention of Relapse
LeukemiaThis study aimed to evaluate the efficacy of interferon α after prophylactic donor lymphocyte infusion (DLI) among high-risk acute leukemia patients undergone unmanipulated blood and marrow transplantation. Hematopoietic stem cell transplantation (HSCT) is an effective treatment option for high-risk acute leukemia (AL). However, post-transplant relapse can occur in some patients, and the prognosis of these patients is usually very poor.Prophylactic DLI can decrease the risk of relapse of high-risk AL patients. Interferon α-2b exerts a relatively strong immunomodulatory effect. It can kill AL cells by regulating T-cell and/or natural killer cell functions.Consequently, interferon α-2b may have potential value for high-risk AL patients after transplantation. The study hypothesis: Using interferon α-2b after prophylactic DLI following hematopoietic stem cell transplantation in patients with high-risk AL can further reduce relapse rate and improve leukemia-free survival.
A Novel Immunotherapy PD-1 Antiboty to Suppress Recurrence of HCC Combined With PVTT After Hepatic...
Hepatocellular CarcinomaHepatic resection is the most effective curative treatment for resectable HCC, whereas frequent recurrence usually impaired the efficacy of hepatic resection and contributed poor survivals. PVTT has been certified as an independent risk of early recurrence. Although TACE has been used to decrease the intraheptic recurrence. However, the intraheptic recurrence rate remains high and meanwhile it is uncapable to suppress extrahepatic recurrence. In addition, systematic therapy the small molecular target antiangiogenesis medicine sorafenib were used to prevent recurrence. Unfortunately, the STORM trial shows that postoperative antiangiogenesis therapy was failed to suppress recurrence and prolong survival period for HCC patients. Thus, novel effective systematic therapy to suppress postoperative recurrence is in urgent need. At present, the PD-1 antibody has presented a promising and safe therapeutic result of unresectable HCC and provided good survival benefit for advanced HCC patients. Consistent with this, we proposed a hypothesis that a novel immunetherapy using the PD-1 antibody could suppress postoperative recurrence and prolong HCC patients survival period effectively.
Use of Platelet Indices for Prediction of Recurrent Miscarriage
Recurrent MiscarriagePlatelet indices might be a marker for platelet activation, and thus could predict thrombosis. This might be the cause in some cases of recurrent miscarriage. This study aims to evaluate the use of platelet indices -as a simple test- to predict recurrent miscarriage.
Colvera for Detection of Disease Recurrence
Colorectal AdenocarcinomaTo compare the sensitivity and specificity estimates of Colvera with that of a commercially available CEA test for detection of recurrent disease in CRC subjects who are undergoing surveillance for recurrence.
Antibiotic Bladder Instillations vs. Oral Suppression for the Treatment of Recurrent Urinary Tract...
Recurrent Urinary Tract InfectionThis is a research study that aims to determine if antibiotic bladder instillations (placing an antibiotic directly into the bladder) over several sessions at the office is a good option to prevent recurrent urinary tract infections, in comparison with oral suppression therapy (taking daily antibiotics in the form of pills by mouth). Oral antibiotic suppression therapy is currently the most common treatment route for recurrent urinary tract infections in post-menopausal women. The bladder antibiotic instillation may overcome the disadvantages of oral suppression therapy such as antibiotic resistance, certain side effects, and recurrence of infections after finishing the treatment course.
Feasibility and Acceptability of a Smartphone App to Assess Early Warning Signs of Psychosis Relapse...
Schizophrenia RelapseSchizophrenia3 moreAbout 1 in 100 people will experience an episode of psychosis. Some people will only experience one 'psychotic episode' and about a quarter of people make a full recovery. Others will have recurring periods of problems ('relapses'), perhaps at times of particular stress. As people often find psychosis distressing, this study looks at ways to help them stay well in the future. There is growing evidence that 'early signs' interventions can prevent relapses of psychosis. Early signs are things that might happen when people start to become unwell. For example some people start to sleep badly when they are becoming unwell. Most people with psychosis can identify early signs emerging in the weeks before relapse. In early signs interventions, service users are taught to recognise early signs that their mental health may be deteriorating so that they can take action to avoid becoming unwell. Although early signs interventions show promise, the investigators suggest that they can be improved by more accurate assessment of relapse risk. This might be achieved by monitoring 'basic symptoms' in addition to conventional early signs of relapse. Basic symptoms are subtle, subclinical disturbances in one's experience of oneself and the world. Typical basic symptoms include: changes in perceptions, such as increased vividness of colour vision; impaired tolerance to certain stressors; difficulty finding or understanding common words. In this study the investigators want to design and test a mobile phone app to help monitor basic symptoms. They hope that the app might help service users to stay well in the future. During the study the investigators will ask participants to use the app once a week for 6 months. At the end of the study they will interview them about their experiences of using the phone app and participating in the study.
Effect of Hydroxychloroquine on Atrial Fibrillation Recurrence
Atrial FibrillationAtrial fibrillation is the most common arrhythmia in clinic. It can lead to heart failure or stroke, and has a high disability rate and mortality rate. At present, although radiofrequency ablation can cure atrial fibrillation, the success rate is only 50~70%, and has a high recurrence rate. In recent decades, no effective new antiarrhythmic drugs have been introduced, but there are side effects in long-term application of the existing antiarrhythmic drugs. Therefore, it is urgent to provide new and effective antiarrhythmic drugs. Autophagy level of atrial myocytes in atrial fibrillation patients was significantly higher than that in sinus rhythm. Hydrochloroquine (HCQ) is a hydroxychloroquine sulfate composed of 4- amino quinoline compounds. As an effective inhibitor for autophagy, HCQ could effectively prevent the increased autophagy level of atrial myocytes in atrial fibrillation rabbits, prevent atrial effective refractory period (AERP) shortening, and decrease the rate and duration of atrial fibrillation. At present, hydroxychloroquine is mainly used in the treatment of rheumatic immune system diseases and anti malaria. Because of its good safety and small side effects, HCQ has become an indispensable member of drugs in the combined treatment of rheumatoid arthritis and systemic lupus erythematosus patients. In recent years, studies have reported that hydroxychloroquine plays an important role in the prevention and treatment of cardiovascular diseases. Chloroquine could effectively shorten the action potential of atrial myocytes by blocking the inward rectifier potassium ion channel (Kir2.1) and reducing the inward potassium ion current Ik1. HCQ could also reduce 72% (P=0.002), and 70% for the risk of coronary heart disease, stroke, and transient ischemic disease. So the investigators speculate that HCQ may be a potential drug to block the occurrence of acute atrial fibrillation.
Ex Vivo Drug Sensitivity Testing and Mutation Profiling
Recurrent Childhood Acute Myeloid LeukemiaRecurrent Childhood Acute Lymphoblastic Leukemia13 moreThis study is a prospective, non-randomized feasibility study. Freshly isolated tumor cells from patients will be screened using state-of-the-art viability assay designed for ex vivo high-throughput drug sensitivity testing (DST). In addition, genetic information will be obtained from cancer and normal (germline) tissue and correlated with drug response. This study will provide the platform for informing treating physician about individualized treatment options. The main outcome of this study will be the proportions of the patients whose treatment was guided by the personalized medicine approach.
