Hemodynamic, Laboratory, and Clinical Outcomes of Hemoadsorption Therapy

This single-center retrospective observational cohort study aims to evaluate the clinical, hemodynamic, and laboratory effects of adjunctive hemoadsorption therapy in critically ill adult patients treated in the Intensive Care Unit of Flór Ferenc Hospital, Hungary, between January 1, 2020, and May 31, 2026. Patients who received CytoSorb® or Efferon LPS® hemoadsorption therapy will be included. The study will assess changes in vasopressor requirements, hemodynamic parameters, inflammatory biomarkers, liver function tests, tissue perfusion markers, and oxygenation following hemoadsorption treatment. Clinical outcomes, including intensive care unit length of stay, all-cause mortality occurring during the patient's stay in the intensive care unit (ICU mortality), and 28-day and 90-day mortality, will also be evaluated. Data will be collected retrospectively from anonymized medical records, and no study-related interventions will be performed.

Body Mass Index and Spinal Anesthesia in Urological Surgery

This single-center prospective observational study investigates the effect of body mass index (BMI) on intraoperative vasopressor requirements and spinal block characteristics in adult patients undergoing urological surgery under spinal anesthesia. Participants are classified into two cohorts according to BMI (\<27.5 kg/m² and ≥27.5 kg/m²).Patient enrollment for this prospective observational study started before trial registration; therefore, this record represents a retrospective registration.

Enteral Versus Parenteral Nutrition During Recovery After Shock

This study compares enteral nutrition and parenteral nutrition in critically ill adult patients recovering from shock while receiving decreasing doses of vasopressors in the intensive care unit. Eligible patients will be randomly assigned to receive either enteral or parenteral nutrition during the early recovery phase of shock. The study aims to determine whether enteral nutrition improves clinical outcomes, including ICU mortality and ICU-acquired infections, compared with parenteral nutrition.
