Biopsy

The purpose of this study is to evaluate the feasibility and safety of using the LUMENA guidance system during clinical procedures in patients undergoing CT-guided needle Placement for kidney, liver, lymph node, abdominal mass and lung ablation/biopsy.

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.

This prospective longitudinal interventional study aims to evaluate the effect of structured peri-procedural nursing interventions on resilience and anxiety in men undergoing transrectal prostate biopsy. Participants will receive a standardized nursing intervention before and after the biopsy procedure. Resilience, anxiety, pain, lower urinary tract symptoms, and perceived nursing support will be assessed at predefined time points. Histopathological findings (benign or malignant) will be used for subgroup analyses. The study is conducted at the University Clinical Hospital Mostar, Bosnia and Herzegovina.

This is an observational, prospective, multi-center trial designed to evaluate clinical outcomes in kidney transplant recipients undergoing TruGraf and TRAC monitoring. Approximately 15 U.S. sites

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.

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 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.
