Actualities in Procedural Sedation: Remimazolam

Remimazolam is a new, ultra-short-acting benzodiazepine approved in Romania for procedural sedation. It shows significant clinical benefits compared to other sedatives like Propofol or Midazolam, especially in elderly or high-risk patients. Advantages include better hemodynamic stability, reduced respiratory depression, lower incidence of postoperative delirium, and rapid recovery without residual sedation. It is metabolized by liver esterases and is less affected by organ dysfunction. Clinical studies suggest that remimazolam may be a safer and more effective alternative in procedural and general anesthesia. The findings support the development of institutional protocols for its use, particularly in high-risk populations and endoscopic procedures.

Dalargin for Prevention of Organ Disfunction in High-Risk Abdominal Surgery

Major abdominal surgeries (e.g., gastrectomy, pancreatectomy, colectomy) carry a high risk of life-threatening postoperative complications, including multiorgan disfunction syndrome (MODS), acute kidney injur (AKI), miocardial injury after non-cardiac surgery (MINS) and severe infections. These complications are driven by ischemia-reperfusion injury, leading to oxidative stress and a systemic inflammatory response. Despite advances in surgical and anesthetic techniques, there are no effective pharmacological strategies for personalized prevention of these events, which adversely affect recovery and survival. In this context, opioid receptor agonist, particularly senthetic analogs of Leu-enkephalin such as Dalargin, have emerged as promising agents for pharmacologica preconditioning. Preclinical evidence suggests their ability to mitigate oxidative stress and inflammation by moduating key signaling pathways . The potential for these peptides to protect andothelial function and reduce organ damage presents a novel therapeutic avenue. This study aims to clinically test the hypothesis that perioperative intravenous infusion of Dalargin reduce the incidence and severity of postoperative organ dysfunction. Patients undergoing high-risk abdominal surgery will be randomized to receive either a 72-hour continuous of Dalargin (following a defined dosage regimen) or an identical placebo infusion. the study will also integrate an assessment of genetic polymorphism ( e.g., in NRF2, OLR1, TLR9 genes) to explore personalized approaches to risk stratification and prevention.

Impact of Metabolite Supplementation to Restore Mitochondrial Dysfunction During Septic Shock: a Preclinical Study

Septic shock is defined as a subset of sepsis with severe metabolism alterations, leading to organ failure. Septic shock is associated with a high mortality, around 40% according to the SEPSIS 3 definition. Metabolic alterations are responsible for lactic acidosis, and results in mitochondrial dysfunction. This study aims at evaluate the impact of exogenous metabolites on restoring mitochondrial function in septic shock patients with lactate acidosis. Mitochondrial metabolism (quantitative analysis, mitochondrial function) in intact Peripheral Blood Mononuclear Cells (PBMC) will be isolate and analyse from patients at the early phase of septic shock (admission), at day 2 and 4. Participant's medical history will be recorded: renal and liver metabolism, severity scores and outcomes and the need for supportive care in the intensive care unit (ICU) until 28 days after admission. Furthermore, the investigators will evaluate wether selected metabolites added to the cell culture medium may improve mitochondrial metabolism.

Feasibility Pilot Study to Evaluate the Safety and Performance of the MEX-CD1 Medical Device in ACLF

The goal of this clinical trial is to test the MEX-CD1 hemodialysis medical device in patients suffering from ACLF. The main questions it aims to answer are: * Is the device safe when used according to the instructions for use? * Does the device work as expected by removing the excess of free iron from the blood? Patients will receive 3 MEX-CD1 Slow Low volume CVVHD within 1 week.

Polish Nationwide Register of Hospitalized Patients in Cardiac Intensive Care Units

Cardiac Intensive Care Units (CICUs) provide care for a diverse patient population. Understanding the clinical characteristics, analysis of treatment modalities, and prognosis of patients hospitalized in the CICU are important to improve cardiovascular care. The purpose of this registry is to determine the demographics, clinical, treatment, and prognosis of patients hospitalized in the Polish CICUs. Data from this multicenter, prospective observational study will provide more robust data to facilitate quantitative characterization of cardiac care in contemporary Polish CICUs and enable the development of infrastructure for clinical trials in CICUs.

Burden, Mortality and Supply Costs in Intensive Care Unit Patients

This study systematically observes in a pragmatic trail under real world conditions the association between strategies of therapy (maximal therapy, withhold, withdraw) and treatment success in three endpoint related initial risk groups (high, intermediate, low risk) regarding three endpoints (burden, mortality and supply costs).

Exosome of Mesenchymal Stem Cells for Multiple Organ Dysfuntion Syndrome After Surgical Repaire of Acute Type A Aortic Dissection

Multiple organ dysfunction syndrome (MODS) after surgical repaired for acute type A aortic dissection (ATAAD) is a life-threatening condition. In this study, patients who undergoing surgical repaired of ATAAD immediately or presenting sever MODS after surgical repaired of acute type A aortic dissection will be treated with umbilical cord-derived mesenchymal stem cell.
