Filter by:This protocol focuses on the effect of sleep interventions on improving sleep and building cognitive/brain resilience in older adults with amnestic mild cognitive impairment and sleep disturbance. Two sleep interventions, cognitive behavioral therapy for insomnia (CBTI) and acoustic slow-wave activity enhancement (SWAE), will be utilized in a pilot randomized clinical trial in which participants are randomized to different treatment groups (CBTI or SWAE). Participants will be assessed over a 6-month period in order to examine the impact of sleep treatments on neuropsychological outcomes and cognitively mediated everyday functioning.
Based on the current background and our previous studies, TUS has been proved that rTUS intervention could induce long-term potentiation like (LTP-like) plasticity and neuromodulate the brain cortex in schizophrenia patients. rTUS over the left dorsolateral prefrontal cortex (DLPFC) can alleviate the negative symptoms in schizophrenia. In this double-blind, randomized, sham-controlled study, the efficacy of different treatment options and mechanisms of low-intensity rTUS on negative symptoms will be investigated.
This phase I trial tests the safety, side effects, and best dose of RG1-virus-like particle (VLP) in preventing human papillomavirus (HPV)-related cancers in women. RG1-VLP is a vaccine that aims to protect against rare HPV types not targeted by currently approved HPV vaccines. HPV is a common sexually-transmitted infection that can cause certain genital and oral cancers. RG1-VLP contains a protein of HPV type 16 (HPV16) with a slightly different structure than the licensed Gardasil-9 vaccine. Gardasil-9 is approved by the Federal Drug Administration to help protect against diseases caused by some types of HPV. Gardasil-9 also contains 9 different HPV proteins. Both vaccines contain alum to stimulate the immune system. The usual approach for the prevention of HPV-related cancers for patients who are at increased risk is to consider the currently approved HPV vaccine like Gardasil-9, as well as to be followed closely by their doctor to watch for the development of cancer via routine pap smears. This trial may allow researchers to find out whether the RG1-VLP vaccine can safely trigger an immune response against HPV in healthy women and if it is better or worse than the usual approach for the prevention of HPV-related cancers.
To find out whether left ventricular septal pacing (LVSP)-based cardiac resynchronization therapy (CRT) is superior to right ventricular apical pacing (RVAP)-based CRT in patients with failed left bundle branch pacing at the beginning of chronic heart failure.
Based on the use of the patient's natural defences, immunotherapy mobilizes the immune system to recognize and destroy cancer cells, and it has revolutionized the treatment of lung cancer. However, the effectiveness of immunotherapy varies from patient to patient. At present, we have no weak markers to predict with certainty the efficacy of immunotherapy treatment in a given individual. Current scientific data identifies a number of molecules produced by the cancer cells and their environment which can be detected by various means (blood tests, breath analysis, etc.). The aim of this study is to understand whether the amount of nitric oxide (NO) present in the breath is a more accurate predictor of response to immunotherapy. Participation in this study involves breath testing (to measure FeNO (Fractional exhaled Nitric Oxide)) before receiving the first infusion of immunotherapy, and at the follow-up visit after the 4th course of immunotherapy.
The present study aimed to assess the effectiveness of the combination treatment of Atezolizumab/Bevacizumab, transcatheter arterial chemoembolization (TACE) and I-125 Seeds Brachytherapy (TACE-AB-I) in patients with advanced hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT). The investigators confirmed that the combination therapy yielded better survival data than the combined administration of Atezolizumab/Bevacizumab and TACE (TACE-AB) in patients with advanced HCC and Type I/II PVTT (Based on Cheng's PVTT classification).
Background: ACLR with autologous tendon graft is commonly used for the treatment of ACL injury. However, as the BTI healing is poor, this can lead to a failure rate of 5% in the first-year post-operation; a long and unpredictable rehabilitation period is expected and 35 % of patients never return to preinjury level of sports. Biological enhancement of BTI healing will help to cut down the medical cost related to poor prognosis. As a biodegradable metal, Mg has been developed as implants in orthopaedics for decades, yet without clinical implants developed for ACLR. Our team has been working on this area in the past 10 years preclinically. Our animal studies showed that supplementation of magnesium wire significantly promotes osteogenesis at BTI and improves mechanical strength in ACLR. Recently, our team developed a highly pure (99.99%) Mg wire (Fig 2) in collaboration with metallic engineers for tendon graft braiding during ACLR and with its improved physical quality and strength, it is suitable for graft braiding and then its degradation in vivo can promote tunnel bone formation and bone tendon interface integration. Objective: To investigate if anterior cruciate ligament (ACL) reconstruction augmented with magnesium (Mg) wire enhances osteogenesis at the bone-tendon interface (BTI), improving post-op rehabilitation and leading to better clinical outcomes. Hypothesis: Patients with ACL reconstruction using Mg wire will experience improved osteogenesis at the BTI, more effective rehabilitation, and superior knee strength and function. Design and Subjects: A multicentre, double-blinded, randomized controlled trial will recruit patients aged 18-30 with unilateral ACL tear for primary ACLR with a hamstring graft at four sites. Instruments: Mg-based wire. Interventions: Participants will receive either 99.99% purity Mg wire or 2-0 vicryl as a control. Main Outcomes: Osteogenesis will be assessed by High-Resolution Peripheral Quantitative Computed Tomography (HR-pQCT), muscle strength via Biodex tests, and functional recovery with International Knee Documentation Committee (IKDC) and Tegner scores at multiple post-op intervals. Knee stability will be checked with KT-1000 arthrometer. Blood samples will be analyzed for inflammatory markers and metabolic effects related to Mg wire. Data Analysis and Expected Results: A repeated-measures ANOVA will be utilized for data analysis. The expectation is that Mg wire augmentation will significantly enhance osteogenesis at the BTI and improve rehabilitation outcomes.
The goal of this clinical trial is to evaluate the safety and tolerability of multiple doses of human umbilical cord mesenchymal stem cell injection in patients with Mild to Moderate Acute Respiratory Distress Syndrome (ARDS), and to further explore the efficacy, pharmacodynamic profile and appropriate dose of administration to provide a basis for the use of safer and more effective treatments for patients with Mild to Moderate Acute Respiratory Distress Syndrome (ARDS). Participants are required to sign an informed consent form and, after undergoing a series of tests and meeting the protocol's entry and exclusion criteria, are assigned to a dose group for intravenous infusion of human umbilical cord mesenchymal stem cells. Each subject will receive three infusions.
Most patients with multiple myeloma (MM) die due to relapse resistant to current treatment, including treatment with anti-B cell maturation antigen (BCMA) CAR-T cells. To overcome some of the potential limitations of this therapy, a new and optimized Anti-BCMA CAR-T has been developed, with the aim of using it in patients with MM who relapse after Allogeneic Haematopoietic Haematopoietic Progenitor. This trial is a prospective phase I/II trial with a 3+3 design. Once Dose Limiting Toxicity is identified, Phase II will begin to assess the efficacy of the procedure.
The goal of this observational study is to estimate the prevalence of HPV infections anal and ENT level and according to HIV status in transgender (TG) population. The main question it aims to answer is: - What is the prevalence of HPV lesions in transgender population (TG); - What kind of high risk HPV (hrHPV) and low risk HPV (lrHPV) are detected at the genital, anal and ENT level
