Kidney Failure, Acute

This retrospective observational study aims to evaluate the clinical characteristics and in-hospital outcomes of critically ill adult patients who underwent hemodialysis (HD) or continuous venovenous hemodiafiltration (CVVHDF) in the Emergency Department of Antalya Training and Research Hospital between January 1, 2023, and August 1, 2026. Medical records will be reviewed to collect information on patient demographics, comorbidities, clinical findings at admission, vital signs, renal replacement therapy indications, laboratory results before and after treatment, treatment modality, treatment-related complications, need for intubation or vasopressor/inotropic support, intensive care unit admission, length of stay, and hospital outcomes. The primary outcome is in-hospital mortality. Secondary outcomes include emergency department mortality, intensive care unit admission, ward admission, discharge status, emergency department and hospital length of stay, need for intubation or vasopressor/inotropic support, treatment completion, treatment-related complications, and changes in laboratory parameters before and after renal replacement therapy. No additional intervention, test, treatment, or biological sample collection will be performed as part of this study.

Acute kidney injury (AKI) and chronic kidney disease (CKD) impose a significant global health burden. Yet, no effective therapies currently exist for AKI, and only a few are available for CKD. Despite significant effort from industry and academia, development of pharmacologic therapies for AKI and CKD has been hampered by: Non-predictive animal models The inability to identify and prioritize human targets The limited availability of human kidney biopsy tissue A poor understanding of AKI and CKD heterogeneity Historically, AKI and CKD have been described as single, uniform diseases. However, growing consensus suggests that different disease pathways lead to different subgroups of AKI and CKD (AKIs and CKDs). Access to human kidney biopsy tissue is a critical first step to define disease heterogeneity and determine the precise molecular pathways that will facilitate identification of specific drug targets and ultimately enable individualized care for people with AKI and CKD. A number of research centers across the United States are collaborating to bring state-of-the-art technologies together to: * Ethically obtain and evaluate kidney biopsies from participants with AKI or CKD * Define disease subgroups * Create a kidney tissue atlas * Identify critical cells, pathways, and targets for novel therapies The KPMP is made up of three distinct, but highly interactive, activity groups: * Recruitment Sites: The recruitment sites (RS) are responsible for recruiting participants with AKI or CKD into the longitudinal study and performing the kidney biopsy. * Tissue Interrogation Sites: The tissue interrogation sites (TIS) are responsible for developing and using innovative technologies to analyze the biopsy tissue. * Central Hub: The central hub is responsible for aggregating, analyzing, and visualizing the generated data and providing scientific, infrastructure, and administrative support for the KPMP consortium.

The study aims to improve the safety of the electroporation ablation (PFA) procedure by using muscle relaxants to reduce skeletal muscle damage during the procedure. It will also assess myocardial damage to improve the procedure's quality and speed up recovery after the procedure.

Evaluation of non-invasive prognostic parameters in patients developing ACLF and renal failure in patients receiving and not receiving transjugular intrahepatic portosystemic shunt (TIPS). Patients are cared according to the local standardized follow up program. Clinical and laboratory data from standard patient care are evaluated for potential prognostic value.
