Examining Safety, Efficacy and Feasibility of Preoperative Propranolol in Patients With PDAC.
The IMPULS trial is a randomized, triple-blinded, placebo controlled, single center, pilot trial examining the efficacy and safety of preoperative propranolol in patients scheduled for pancreatic cancer surgery. The study is conducted as a type 1 hybrid efficacy-implementation trial of 30 patients. This study is designed to provide pilot data …
An Exploratory Study of Arginine Supplementation and the Postoperative Immune REsponse
ASPIRE is a nutrition study focusing on the effect of arginine supplementation on immune function in postoperative infants. The investigators will explore the effect of current intravenous feeding (parenteral nutrition (PN)) formulations and oral arginine supplementation on blood arginine levels and the genes that are involved in body nutrition and …
Inflammatory Mediators of Acute Kidney Injury in Intensive Care
Acute kidney injury (AKI) affects more than 50% of patients admitted to the intensive care unit. The most common underlying cause is sepsis. Severe AKI in combination with sepsis is associated with high mortality. The mechanisms for sepsis-induced AKI are largely unknown. Our hypothesis is that the inflammatory response to …
A Randomized Comparison Between 0.67 mcg/kg, 1 mcg/kg, and 1.33 mcg/kg of Perineural Dexmedetomidine for Ultrasound-Guided Infraclavicular Block
This study will compare three different doses of perineural dexmedetomidine 0.67 mcg/kg, 1 mcg/kg, and 1.33 mcg/kg as adjuvants to local anesthetics for ultrasound-guided infraclavicular brachial plexus blocks (ICBs). Our research hypothesis is that 1.33 mcg/kg will provide a 15%-longer duration than 1mcg/kg, which in turn will provide a 15%-longer …
CMR Right Ventricular Contractile Reserve Following Lung Resection
Feasibility study investigating CMR dobutamine stress testing before and after lung resection
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: …
Risk Factors for AKI in Patients Undergoing VATS for Pulmonary Resection
This study aims to investigate the potential factors contributing to the development of Acute Kidney Injury (AKI) in patients undergoing pulmonary resection with Video Assisted Thoracoscopic Surgery (VATS) for lung malignancy. The study will focus on demographic data, laboratory parameters, perioperative fluid management, and haemodynamics. The research will be conducted …
Hyperpolarized 13C Pyruvate-MRI and FDG-PET in a Single Exam for the Prognosis of Ischemic Cardiomyopathy
This prospective, non-blinded, single-center, translational research study aims to validate a multimodal advanced imaging exam for cardiac viability. The protocol utilizes three distinct imaging modalities: Single Photon Emission Computed Tomography Myocardial Perfusion Imaging (SPECT MPI), 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), and Hyperpolarized Carbon-13 (HP-13C) Pyruvate Magnetic Resonance Imaging (MRI). Under …
Effect of Dexmedetomidine on Microsurgery Reconstruction in Cancer Patient
This double-blinded randomized controlled trial aims to investigate the effect of intraoperative dexmedetomidine administration on early flap viability and microvascular integrity in cancer patients undergoing elective microvascular reconstructive surgery. The primary outcome is clinical flap viability within 48 hours postoperatively, assessed using a standardized scoring system based on flap color, …
Multimodal Analysis of Endomyocardial Biopsies
The goal of this observational study is to pursue a multimodal approach to identify the molecular signatures and immune signalling molecules of various myocardial diseases and thereby contribute to improving diagnosis and therapy. The main aim is: -Identification of molecular profiles (e.g., proteome, lipidome, metabolome) and immune signalling profiles that …
