Clinical Study of Chemogenetic Gene Therapy With AAV for Parkinson's Disease Using Stereotactic Surgery in the Subthalamic Nucleus

Parkinson's Disease (PD)

The investigators propose a gene therapy strategy for Parkinson's disease - a chemogenetic inhibition technique to intervene in the abnormal activity of the subthalamic nucleus in Parkinson's patients. The investigators design and construct a therapeutic injection agent called STP-001, through an efficient adeno-associated virus capsid (AAV), a neuronal promoter (hSyn), and a chemogenetic effector element (hM4Di). Then, the drug was accurately injected into the bilateral subthalamic nuclei through stereotactic surgery. After the surgery, combined with clozapine, the abnormal activity of the subthalamic nucleus was precisely intervened to improve the core motor symptoms of Parkinson's disease.

Phosphate-Containing Replacement Fluid for Patients Undergoing CRRT

Acute Kidney Injury Sepsis Critically Ill Patients Requiring Continuous Renal Replacement Therapy

Brief Summary: Evaluating a New Phosphate-Containing Fluid for Blood Purification (CRRT) Why is this study being done? Patients in the Intensive Care Unit (ICU) often need a treatment called Continuous Renal Replacement Therapy (CRRT). This is a type of blood purification that acts like an artificial kidney to clear toxins and extra fluid from the body. A common problem during this treatment is that vital minerals, like phosphate, are washed out of the blood along with the toxins. Low phosphate can lead to muscle weakness and breathing problems. Currently, doctors must manually add phosphate to the treatment fluids, which can be inconsistent. This study aims to test a new, pre-mixed fluid that already contains phosphate to see if it works better and is safe. What are the main questions the study aims to answer? Does the new fluid help keep phosphate at a healthy level in the blood during the first 72 hours of treatment? How does the new fluid affect kidney function compared to the standard fluid? Is the new fluid safe for patients to use? Who can take part in this study? The study is looking for adults (18 and older) who: Are in the ICU and need CRRT treatment as decided by their doctor. Are expected to need this treatment for at least 72 hours. Are willing to participate (or have a legal guardian who agrees). People who are pregnant, have known allergies to the fluid ingredients, or have very low blood pressure that cannot be corrected may not be able to join. How will the research happen? This is a "double-blind" study involving 220 participants across 15 hospitals. This means neither the patients nor the doctors will know which fluid is being used until the study is over. Participants will be put into one of two groups by a computer: Group 1 (New Fluid): Receives the blood purification fluid that has phosphate already in it. Group 2 (Standard Fluid): Receives the standard fluid that does not have phosphate. What will participants have to do? Receive Treatment: Participants will receive their assigned fluid during their normal CRRT care for up to 7 days. Blood Tests: Doctors will take regular blood samples to check mineral levels and kidney health. Monitoring: The medical team will closely watch participants for any side effects or safety concerns. Follow-up: There will be a safety check-up 7 days after the treatment ends. Possible Benefits and Risks The new fluid may help prevent low phosphate levels, which could help with recovery. However, as with any medical treatment, there is a risk of side effects or electrolyte imbalances. The research team will monitor every participant 24/7 to ensure their safety.

Caring for Dementia Caregivers in Ethnic Immigrant Communities

Stress and Well-being of Family Caregivers of Persons With Dementia

Many caregivers of people with Alzheimer's disease or other dementias-especially those in immigrant communities who don't speak English well-don't get access to helpful, proven support programs. This is especially true for Korean American caregivers. To address this, our team adapted an existing caregiver support program (called the Savvy Caregiver Program) to better fit Korean culture and language. This new version, called K-Savvy, is a 6-week online program taught in Korean. In an earlier small study, K-Savvy worked well: caregivers found it helpful, were willing to use it, and showed fewer symptoms of depression. Now, we want to study it more carefully to see how well it really works and why. Our study has two main goals: Goal 1: We will measure whether K-Savvy improves caregivers' well-being-specifically whether it reduces stress and depression and helps them feel more positive about caregiving. We will also look at why it works, focusing on whether it changes how caregivers think about their situation (for example, feeling less overwhelmed and more confident). Goal 2: We will talk directly with caregivers and program instructors to understand their experiences with K-Savvy. This will help us learn what worked well, what didn't, and why.

Tiaoshen Anti-cancer Protocol and CBT for Insomnia and Survival in Ovarian Cancer

Ovarian Neoplasms Malignant Sleep Initiation and Maintenance Disorders Medicine, Chinese Traditional Chinese Herbal Medicine +1

Study Title: A Multicenter, Randomized Controlled Trial of Tiaoshen Anti-cancer Protocol Combined with Cognitive Behavioral Therapy for Insomnia in Improving Sleep and Survival in Ovarian Cancer Patients Purpose: This study aims to evaluate whether a combined therapy of traditional Chinese medicine (TCM) and modern psychotherapy can improve sleep and potentially extend survival for patients with ovarian cancer. Many patients experience severe, cancer-related insomnia, which lowers quality of life and may affect treatment outcomes. Intervention \& Design: This is a randomized, double-blind, placebo-controlled trial conducted across multiple hospitals. Approximately 360 eligible patients with advanced ovarian cancer and significant insomnia will be enrolled. Participants will be randomly assigned to one of two groups for the initial 18-week phase: Experimental Group: Receives the Tiaoshen Anti-cancer herbal formula granules plus standard Cognitive Behavioral Therapy for Insomnia (CBT-I). Control Group: Receives inactive placebo granules plus the same standard CBT-I. Neither the participants nor their treating doctors will know which granules are assigned during this phase. The primary goal is to compare the improvement in sleep quality between the two groups. Key secondary goals include assessing the therapy's impact on patients' anxiety, depression, overall quality of life, and the length of time before the cancer progresses (progression-free survival). All patients will receive standard-of-care chemotherapy.

Percutaneous Embolectomy, Low Dose Thrombolysis or Heparin for Intermediate High Risk Pulmonary Embolism (STRATIFY II)

Pulmonary Embolism

The STRATIFY II trial investigates the efficacy of three different approaches to reducing thrombus burdon in patients with acute intermediate high-risk pulmonary embolism: percutaneous embolectomy (the AlphaVAC(R), AngioDynamics or the Flow Triever® system, INARI medical), Low intravenous thrombolysis (Alteplase 10 mg) and heparin with the option to perform full-dose thrombolysis. As a co-primary secondary end point the trial assess the incremental efficacy of the embolectomy vs the catheter based low dose thrombolysis approach. Thus the two main hypothesis being tested are: 1. Thrombus burden reduction after 48-96 h is increased with a catheter based (embolectomy or low-dose alteplase) compared to the a heparin with optional high dose thrombolysis approach (1st co-primary outcome) 2. Thrombus burden reduction after 48-96 h is increased with percutaneous embolectomy compared to low-dose alteplase (2nd co-primary outcome)
