Active clinical trials for "Acute Kidney Injury"

Retrospective study that aims to examine the presence of acute kidney injury (AKI) during major abdominal surgery, non- cardiac surgery. Using clinical and biochemical data in order to establish AKI frequency and risk factors.

The aim of this study is to investigate the changes in renal regional oxygen saturation (rSO2) monitored by near-infrared spectroscopy (NIRS) and its relationship with the occurrence of postoperative AKI.

Retrospective, multicenter, comparative, post-market study of the Tablo Hemodialysis System in hospitalized participants with End-Stage Renal Disease or Acute Kidney Injury.

There is a high prevalence of postoperative acute kidney injury (AKI) in patients who undergo intra-abdominal surgery, and it is particularly common in the elderly. Identifying high-risk patients for postoperative AKI early can facilitate the development of preventive and therapeutic management strategies. The goal of this retrospective study is to investigate the predictive value of preoperative nutritional status, as measured by three scoring systems - the geriatric nutritional risk index (GNRI), prognostic nutritional index (PNI), and controlling nutritional status (CONUT) score - on postoperative AKI in elderly patients undergoing major abdominal surgery.

Trimethoprim/sulfamethoxazole (TMP/SMX, cotrimoxazole) is the first-line therapy for Pneumocystis jirovecii pneumonia and bacterial infections in critically ill patients, where acute kidney injury (AKI) and renal replacement therapy (RRT) are regularly observed. Both may change half-life and subsequent concentrations. Specifically, Trimethoprim (TMP) is eliminated renally, whereas sulfamethoxazole (SMX) elimination is 80%metabolic/20%renal. Despite decades of cotrimoxazole use, data in acute kidney injury (AKI) are scarce and no consensus on dosing strategy has been established. Besides, pharmacodynamic parameter has not been determined, leading to an uncertainty on the dosing regimen.

This study is a service evaluation to assess the impact of compliance of Acute Kidney Injury care bundle (AKI-CB) on clinical and renal outcomes. The AKI care bundle is coupled with an interruptive electronic alert, which is triggered by the first attempt to order blood tests or medications on patients who have been identified as having AKI by the electronic recognition from serum creatinine results. The interruptive alert will warn the clinician about AKI and request them to complete the AKI care bundle. Once the AKI care bundle is completed, the clinician is able to request blood tests or medication. The clinician will be able to override the alert only after stating the reason. Education with respect to importance of AKI and the AKI-CB is provided every four months when junior doctors rotated through different specialities and also at clinical governance days. The investigators will compare AKI episodes, which have the AKI-CB completed early (defined as within 24 hours of availability of the blood results) with those who either had the AKI-CB completed late (defined as after 24 hours of availability of the blood results) or not completed at all. The AKI patients who either had the AKI-CB completed late or not completed will be considered as not having the AKI-CB completed for this analysis.

This study consists of two substudies. The first substudy: 'Renal resistive index in critically ill patients with cardiogenic and septic shock' Design: cross-sectional observational Aim of this project is: to determine whether critically ill patients with cardiogenic and septic shock have an elevated Renal Resistive Index and to determine whether Renal Resistive Index differs between cardiogenic/hypovolemic shock and shock due to sepsis/systemic inflammation (SIRS) to determine the relation between the (change in) renal vascular resistance and Markers of the systemic - and the microcirculation Fluid status as quantified by bioimpedance analysis Concomitant renal function The second substudy: 'Predictive value of the Renal Resistive Index on ICU admission and its course for the development of acute kidney injury in critically ill patients with cardiogenic and septic shock' Design: longitudinal observational The aim of this project is: to determine whether the renal resistance index on admission to the intensive care unit can predict the development of acute kidney injury (AKI) in critically ill patients with shock to investigate if the renal resistance index on admission to the intensive care unit is an independent predictor of the development of AKI or depends on the severity and duration of shock and other known risk factors of AKI such as comorbidity and use of nephrotoxic drugs Aim of the large research project is to determine whether the Renal Resistive Index could become a monitoring tool for intervention studies aiming to prevent acute kidney injury or protect the kidney.

Purpose: To evaluate the accuracy of the AVERT PLUS to monitor contrast volume used during angiographic procedures. This will be a first in man prospective observational study of the accuracy of this system to quantify contrast volume used during clinically indicated angiography in the cardiac catheterization laboratory.

Introduction: Based on single-center data, approximately 1 of every 3 newborns admitted to tertiary level neonatal intensive care units (NICU) develops acute kidney injury (AKI), and those with AKI have significantly worse outcomes. To stimulate discussion among researchers, the NIH NIDDK sponsored a workshop on neonatal AKI in April 2013. At that workshop, the group recognized the need to improve collaborations between neonatologists and nephrologists within and across centers. The investigators have created a multi-institutional, multi-disciplinary group, Neonatal Kidney Collaborative (NKC), in order to address the following critical needs identified at the workshop: AWAKEN is the inaugural study of this new collaboration. Development of a standardized evidence-based definition of neonatal AKI Evaluation of risk factors that predispose neonatal to AKI Investigation into how fluid provision/ balance impacts biochemical and clinical outcomes

The study evaluates how outcome varies among critically ill patients with and without acute kidney injury. Data from the Swedish Intensive care register and other Swedish national registers is used to compare how survival and post discharge renal function differ between critically ill patients with and without acute kidney injury.
