NCT05822570
Hemoglobin (Hb) is the molecule responsible for the transport of oxygen (O2) to the tissues in mammals. The p50 and the Hill coefficient (HC) best describe the ODC. The interaction between Hb and O2 can be influenced by many agents and conditions like temperature, pH, pCO2 and 2,3-diphosphoglycerate (2,3-DPG). During liver transplantation numerous profound physiological changes occur, linked to the different stages of the surgical procedure. Previous studies in humans and animals undergoing liver transplantation have shown that while the ODC seems preserved during preparation and the anhepatic phase, a left shift of the ODC occurs after reperfusion . This left shift of the ODC could imply a decreased release of oxygen to the tissues, probably worsening hemodynamic instability. With this pilot study the investigator aim to measure ODCs at baseline and at different stages during orthotopic liver transplantation in patients in order to get deeper understanding of oxygen delivery and supply during liver transplantation surgery.

Exercise and physical activity in adults with acquired brain injury
NCT06892574
The goal of this clinical trial is to investigate the efficacy and safety of vagus nerve stimulation (VNS) combined with rehabilitation in improving upper extremity motor function after spontaneous intracerebral hemorrhage (ICH). Researchers will evaluate the efficacy and safety of VNS by comparing the improvements of arm motor function post-ICH in the active VNS combined rehabilitation group with that in the sham VNS combined rehabilitation group (actual intensity 0 mA). Participants in this study will undergo a surgical procedure to implant the VNS system and will subsequently recieve a 6 weeks in-clinic therapy, followed by an additional 6 weeks home exercise. During the final 6 weeks, participants will either recieve in-clinic therapy or maintain their home exercise, depending on their assigned group.
