Diabetic ketoacidosis (DKA), a severe complication of diabetes mellitus (DM), is the leading cause of hospitalization, morbidity and mortality in patients with DM (1). DKA is associated with hyperglycemic crises and featured by metabolic acidosis, the production of ketoacids, volume depletion, and electrolyte imbalance. Due to glucose-induced osmotic polyuria and even emesis, volume depletion is a major cause of acute kidney injury (AKI) in DKA patients (2).

This trial will evaluate whether treatment with CRMD001 (unique formulations of the iron chelator, Deferiprone) will reduce morbidity and mortality in subjects with Chronic Kidney Disease (CKD) and additional risk factors. Adult subjects with moderate to severe CKD who are undergoing diagnostic or interventional coronary angiography will be randomized to either placebo or CRMD001 and followed for 90 days. Subjects will receive 8 days of randomized therapy starting 1-3 hours prior to angiography. The primary endpoint of the trial will be the difference in a composite of specified renal and cardiovascular clinical events occurring through Day 90.

Acute kidney failure remains one of the most challenging entities to diagnose in clinical medicine, especially in the field of intensive care. The diagnosis of acute kidney injury is based solely on urine output and serum creatinine, both of which could also be influenced by other factors. A more sensitive and faster diagnostic option would not only be desirable but of utmost clinical importance. Therefore, the investigators aim to identify Neuronal Guidance Proteins (NGPs) as potential biomarkers for the identification and early detection of AKI with this investigation. This investigation aims to identify the possibility of diagnosing acute kidney injury, the subsequent validation of a potential biomarker will then have to take place in a multicenter study approach: Data in preclinical mouse models suggest that SEMA7A as one of the NGPs could be valuable as a biomarker, the study now aims to attempt a preliminary survey in humans and measure various NGPs.

Complications after lung transplantation are almost ubiquitous, among which postoperative acute renal failure may represent more than 50% of lung transplant patients and require extrarenal purification in 5 to 13% of cases. Multiple factors are associated with postoperative acute renal failure. These factors can be classified into preoperative, intraoperative, and postoperative factors. While some postoperative complications are explained by donor and recipient factors, the literature suggests that certain intraoperative events represent modifiable or avoidable risk factors that could be targeted by therapeutic interventions to reduce the risk of postoperative acute renal failure. Some of these factors (intraoperative hemodynamic instability, significant bleeding or hypoxemia) can generate renal hypoxic aggression, alone or in combination. However, to date, there is no validated tool available at the patient's bedside during surgery to detect renal hypoxia or guide interventions to restore renal perfusion during surgery. Yet, as recent recommendations suggest, intraoperative renal protection is an important axis for improving the outcome of lung transplant patients, to the extent that the recommendations of Marczin et al. recommend the establishment of a renal prevention protocol for each patient. Without a tool to guide this plan intraoperatively, anesthesia teams can't establish a renal prevention protocol. This research aims to establish whether renal NIRS is a reliable tool for monitoring intraoperative renal hypoxic aggression predictive of postoperative renal failure. Near-infrared spectroscopy (NIRS) is an optical technology that allows non-invasive measurement of tissue oxygen saturation. This technique is commonly used for intraoperative monitoring of cerebral perfusion in adults and children. Some studies have shown that regional renal oxygen saturation (renal rSO2) measured by NIRS during aortic-coronary bypass surgery under extracorporeal circulation (ECC) is correlated with renal venous oxygen saturation measured by catheterization. It is also associated with the risk of postoperative acute renal failure in patients undergoing cardiac surgery under ECC. However, there are no equivalent data in lung transplant patients, who frequently present with postoperative acute renal failure. In the available literature, no clear threshold of renal desaturation has been established. Because it is assumed that the depth of renal desaturation can be particularly deleterious, in addition to desaturation time, the investigator have chosen to retain in this project the integral of time and magnitude spent under a renal desaturation threshold, aggregated into a renal hypoxia index, during the intraoperative period. The primary objective of this research is to demonstrate the usefulness of measuring the intraoperative renal hypoxia index in predicting the risk of early postoperative acute renal failure

The study's objective is to evaluate the additive value of renal biomarkers (from blood and urine) for identifying individuals at high risk for severe acute kidney injury (AKI) above that of a novel natural language processing(NLP)-based AKI risk algorithm. The risk algorithm is based on electronic health records (EHR) data (labs, vitals, clinical notes, and test reports). Patients will be enrolled at the University of Chicago Medical Center and the University of Wisconsin Hospital, where the risk score will be run in real time. The risk score will identify those patients with the highest risk for the future development of Stage 2 AKI and collect blood and urine for biomarker measurement over the subsequent 3 days.

This observational retrospective study aims to learn about the incidence of acute kidney (AKI) injury in newborns in infants exposed to nephrotoxic drugs with a big data approach. The main question it aims to answer are: Develop a model that can predict the occurrence of AKI in infants admitted to the NICU; Identify the drug or combination of drugs associated with an increased risk of AKI. The group of infants exposed to drugs will be defined based on exposure for at least 1-day tone one or more therapies commonly used in the NICU. Once the AKI event has occurred, the observation of the trend of daily creatinine and diuresis values will be continued for the period covered by the study.

The increasing number of patients who develop perioperative acute kidney injury (AKI) is partly related to the aging population and the increasing number of individuals with chronic comorbidities, particularly those with premorbid chronic kidney disease. Anesthesiologists and surgeons will increasingly have to deal with such patients who are elderly and have comorbidities and require major surgery. The aim of this study was to determine the incidence of postoperative acute kidney injury (primary aim) in patients aged 65 and over who underwent elective major gynecological-oncological surgery under general anesthesia in Ankara City Hospital Gynecology-Oncology Operating Room between January 2020-2022 and were followed up in the PACU in the postoperative period. To investigate risk factors and their results in a retrospective manner in line with the KDIGO criteria (secondary purpose).

Surgery for scoliosis correction, the abnormal curvature of the spine, is a major procedure often undertaken in adolescents. In adult anesthesia, there is a large volume of literature debating how to optimize fluids administered during surgery, as both too much fluid and too little fluid are associated with worse outcomes. The investigators will compare fluid administration based on the measured amount of blood pumped by the heart during each heart beat (goal-directed therapy), against standard anesthetic management. The main outcomes are a) post-surgical kidney dysfunction, b) prevalence of intraoperative hypotension, c) volumes of administered fluids, and d) length of hospitalization.

The general objective of this open, pilot study is to characterize biological parameters related to acute kidney injury among patients undergoing a programmed coronarography with injection of contrast material. The study focuses on two main factors that may influence acute kidney injury: (1) sodium chloride hydration strategy versus sodium bicarbonate hydration strategy and (2) presence of oral L-carnitine treatment versus absence of oral L-carnitine treatment. We will also test for a potential interaction between these two factors.
