MicroRNAs in Acute Kidney Injury
Kidney Injury in Cardiac Surgery - Expression of microRNAsProfiling of microRNAs and long noncoding RNAs (lncRNAs) in patients undergoing cardiac surgery. Analysis: Prediction of acute kidney injury by plasma expression profile of microRNAs?
Preoperative Prediction of Acute Kidney Injury After Cardiac Surgery
Acute Kidney InjuryAlthough acute kidney injury (AKI) frequently complicates cardiac surgery, methods to determine AKI risk are lacking. Renal functional reserve (RFR), the capacity of the intact nephron mass to increase glomerular filtration rate (GFR), represents maximal filtration capacity. We hypothesized that preoperative RFR would predict postoperative AKI.
Effects of Oral Protein Load on Kidney Function in Patients Undergoing Cardiac Surgery
Acute Kidney InjuryAcute kidney injury (AKI) occurs in approximately one-third of patients undergoing cardiac surgery (CS), and represents one of the most significant negative predictors of patient outcome in this population. In the healthy adult, a high protein meal is known to enhance glomerular filtration rate and is mediated by an increase in renal blood flow. The investigators hypothesized that preoperative oral protein load may precondition the kidneys for upcoming insults and reduce the rate of postoperative AKI and long-term renal outcome.
Impact of Perioperative Shedding of the Endothelial Glycocalyx on the Incidence of Postoperative...
Valvular Heart DiseaseEndothelial glycocalyx, the luminal structure of healthy vasculature, plays critical roles in regulation of inflammatory responses, vascular permeability, blood coagulation. It can be easily damaged by ischemia/reperfusion, hypoxemia, oxidative stress, endotoxin. Accordingly, the relationship between the shedding of endothelial glycocalyx and the prognosis of diseases such as diabetes mellitus, atherosclerosis, malignancy has been researched. In cases of cardiac surgery, patients cannot help but be exposed to ischemia/reperfusion, oxidative stress which can damage endothelial glycocalyx. In this research, the investigators would like to discover the impact of perioperative shedding of the endothelial glycocalyx on the incidence of postoperative acute kidney injury in patients undergoing valvular heart surgery.
Determination of the "Tissue Transit Time" (TTT)
Renal InsufficiencyAcuteDetermination of Tissue Transit Time (TTT) as a parameter with high prognostic value to predict the functional course of the differential renal function and the development of the differential renal function after pyeloplasty
HEmoFiltration With Citric Acid Anticoagulation
Acute Kidney InjuryAcute Kidney Failure2 moreProspective observational study of all consecutive cardio-vascular surgical patients treated with post-dilution hemofiltration with regional citrate anticoagulation as first-choice anticoagulation method. The filter life-span was assessed in the context of postoperative cardiac surgical antithrombotic prophylaxis. Reasons for termination of hemofiltration sessions were assessed. The second aim of this study was to assess the influence ACD-A based anticoagulation protocol on acid-base and ion homeostasis in cardiac surgical patients with acute renal failure.
Resuscitation Fluid Choice and Clinical Outcomes
Large Volume ResuscitationAcute Kidney Injury1 moreThis observational study evaluates the potential benefits, costs and clinical outcomes of albumin over saline and other non-saline fluids in patients receiving large volume resuscitation.
Kidney Biomarkers of Acute Kidney Injury in Patients With Knee Arthroplasty
ArthroplastyReplacement2 moreSensitive renal markers have been studied abundantly in connection with open heart, liver and transplantation surgery; however in major orthopaedic surgery their use is anecdotal. The aim of the present study is to evaluate use of sensitive renal markers, NGAL (Neutrophil gelatinase associated lipocalin ), KIM-1 (Kidney injury molecule- 1), LFABP (liver-type fatty acid-binding protein), and IL-18 (interleukin -18), in patients coming for elective TKA (total knee arthroplasty) as a pilot study before large study concerning acute kidney injury in orthopaedic surgery.
Renal Involvement in Hospitalized Children With COVID-19
Acute Kidney InjuryCovid195 moreCovid-19 is an important human and animal pathogen, it mostly causes respiratory and gastrointestinal symptoms. Clinical features range from a common cold to severe diseases such as severe acute respiratory distress syndrome, bronchitis, pneumonia, multi-organ failure, and even death. It seems to be less commonly affecting children and to cause fewer symptoms and less severe disease in this age group compared with adults. Clinicians have observed many extrapulmonary manifestations of COVID-19, as hematologic, cardiovascular, renal, gastrointestinal and hepatobiliary, endocrinologic, neurologic, ophthalmologic, and dermatologic systems can all be affected. This retrospective study that will be conducted at Hamad General Hospital in Qatar, aims to determine the renal involvement in all pediatric patients who were hospitalized with COVID-19 from March 1, 2020, to January 1, 2021.
Point-of-care Ultrasound for Acute Kidney Injury
Acute Kidney InjuryIt is aimed to determine prerenal, renal and postrenal diagnoses of patients with acute kidney injury with POCUS performed in the emergency department. Patients who presented to the emergency department and who have acute kidney injury (AKI) according to the KDIGO criteria will be evaluated and patients diagnosed with AKI will be included in the study. The diagnostic accuracy of POCUS with the AKI etiologies of the patients will be evaluated.
