NCT07040163

Evaluation of Ketamine/Midazolam Sedation vs. Fentanyl/Midazolam Sedation for Image-Guided Percutaneous Procedures in Interventional Radiology

This study aims to reduce pain during interventional radiology (IR) procedures, making the experience better for patients. Typically, doctors use medications like fentanyl and midazolam for sedation. This research will focus on patients undergoing biopsies and drainage procedures, often associated with significant discomfort. Patients will be randomly assigned to receive either fentanyl/midazolam or ketamine/midazolam combinations for sedation. A coordinator will collect information on pain levels and satisfaction, as well as monitor any extra medications needed and side effects. The investigators hope to find that ketamine helps decrease pain and improves satisfaction compared to fentanyl, without increasing complications.

Comparison of FNB to EUS-CNB for Pancreatic Lesions

The primary aim of this study is to compare the tissue specimen quality and diagnostic accuracy of biopsies obtained with one puncture of a regular 22 FNB G needle and the motorized EUS CNB device of pancreatic lesions. The secondary aims are to compare the rate of blood contamination in the specimens obtained from biopsies of pancreatic lesions and the overall procedure duration. The hypothesis of this study is that the proportion of cases in which a single puncture of the lesion in question delivers adequate diagnostic tissue is higher with the motorized EUS CNB than with the 22 G FNB.

Comparation of Endoscopic Biopsy and Postoperative Specimen for the Molecular Diagnosis of Gastric Cancer

This study aims to test the hypothesis that the diagnosis for histological type, histological grade, LAUREN type, HER-2 expression, MSI/dMMR status, and EBV status in gastric cancer is at least as reliable when performed on endoscopic biopsy specimens as on surgical resection specimens.

Molecular Breast Imaging (MBI)-Guided Biopsy

The goal of this pilot clinical trial is to demonstrate supplemental screening MBI (molecular breast imaging) in women with dense breasts. The main questions it aims to answer are: * Does screening MBI find more cancer than screening DBT (3D mammography, digital breast tomosynthesis? * Does screening MBI result in more call-backs for biopsy than DBT? * How well does MBI-guided biopsy conform with pathology reports? Researchers will compare screening MBI to screening DBT to see if MBI is more sensitive to detecting cancer in women with dense breasts. Participants will * Receive both screening DBT and screening MBI * Receive either DBT-guided or MBI-guided biopsy (randomly assigned), if required by the screening images

The Selection of Initial Treatment Regimens for Adolescent Nephrotic Syndrome.

Given that the treatment strategy for adolescent PNS has a significant impact on growth and development, but there are few cases and a lack of clinical research, this study plans to collaborate with several domestic top-tier children's nephrology centers to conduct a retrospective real-world study of adolescent PNS. The aim is to understand the current diagnosis and treatment status of adolescent PNS and compare the advantages and disadvantages of various therapies, in order to provide a more scientific, rational, and effective treatment plan for adolescent PNS.

Clinical Evaluation of an Augmented Reality Intraprocedural Needle Guidance Platform for Soft Tissue Biopsy

This clinical feasibility evaluation is intended to further characterize and quantify the potential benefits of the FDA-cleared XR90 Augmented Reality (AR )imaging and guidance platform utilization in percutaneous soft tissue biopsy. This study will seek to build on the findings of safety, procedural benefits, and overall clinical feasibility shown in previous bench, cadaveric, and single-site clinical evaluations.

ZeroHeart Biopsy - Prediction of Deceased Donor Heart Transplant Performance From Organ Donors Using Pre-Transplant Biopsies - A Pilot Study

The goal of this observational study is to evaluate whether molecular analysis of donor heart biopsies taken at the time of organ removal ("Time Zero") can help predict the future function and rejection risk of the transplanted heart in adult transplant recipients. The main questions it aims to answer are: * Can early molecular injury in the donor heart, caused by brain death or circulatory death, be detected at the time of organ removal? * Can these early molecular findings predict short-, mid-, and long-term transplant outcomes, such as graft function or rejection? Participants will: * Include heart donors whose hearts are being transplanted (both standard and marginal donors, including DBD and DCD cases) * Provide two small biopsies from the donor heart at the time of organ removal: one for routine pathology, one for microarray-based molecular analysis * Have routine follow-up biopsies after transplantation as part of standard care (no additional procedures required beyond medical standard) Researchers will compare biopsy results from different donor types (standard vs. marginal, DBD vs. DCD) to see if early molecular signals are linked to later heart transplant outcomes.
