Filter by:The aim of this study was to identify and validate novel biomarkers for predict acute kidney injury (AKI) subphenotype, major adverse kidney events and other poor outcomes.
The objective is to determine the effectiveness of pulsatile flow during cardiopulmonary bypass to reduce the incidence of acute kidney injury after cardiac surgery. Investigators will also evaluate the safety and impact of pulsatile flow on clinical outcomes compared to non-pulsatile flow during cardiopulmonary bypass.
Liver transplantation (LT) is a high-risk surgery for hemodynamic instability and haemorrhagic shock with a high-risk of acute kidney injury (AKI). Indeed, the incidence of post-transplant AKI exceeds 50% in some series with 15% of patients requiring renal replacement therapy. Acute kidney injury after LT is a predisposing factor for chronic renal failure which is independently associated with higher morbidity and mortality. Arginine vasopressin (AVP), an essential stress hormone released in response to hypotension, binds to AVPR1a to promote vasoconstriction. Furthermore, it may have nephroprotective effects with a preferential vasoconstriction of the post-glomerular arteriole resulting in increased glomerular filtration The hypothesis of the present work is that low-dose arginine-vasopressin supplementation reduce posttransplant AKI in liver transplantation.
In our locality, limited studies have discussed AKI in patients with liver cirrhosis and its outcome, therefore we aim to highlight the incidence, patterns, risk factors, and outcomes of acute kidney injury in patients with liver cirrhosis at Sohag University Hospital.
This study aims to investigate the potential factors contributing to the development of Acute Kidney Injury (AKI) in patients undergoing pulmonary resection with Video Assisted Thoracoscopic Surgery (VATS) for lung malignancy. The study will focus on demographic data, laboratory parameters, perioperative fluid management, and haemodynamics. The research will be conducted at SBÜ Ankara Atatürk Sanatorium Training and Research Hospital. The study will involve patients who have given informed consent and will undergo VATS with standard anaesthesia monitoring. Anaesthesia management will follow our routine protocol in our clinic. Patients will be divided into two groups based on whether they have a more than 25% decrease in estimated glomerular filtration rate (t-GFH) and/or a 1.5-fold increase in serum creatinine and/or a 6-hour urine volume of less than 0.5 ml/kg/h. The patients will be divided into two groups based on this definition, and the risk factors between these groups will be analysed. The preoperative routine blood values, demographic data (age, gender, height, weight, and BMI), ASA physical status, smoking and alcohol habits, comorbidities, and regular medication use will be recorded. Intraoperative urine output and haemodynamic parameters will also be monitored. Routine blood gas analysis, blood urea nitrogen (BUN), glomerular filtration rate (GFR), albumin, haemoglobin, sodium, potassium, chlorine, and magnesium will be measured and recorded, along with urine output and t-GFH. Patients will be evaluated in the hospital on the day the surgeon calls for a postoperative check-up and on the 30th postoperative day to see if there are any complications.
Heart failure is a syndrome that progresses with symptoms and signs caused by cardiac dysfunction and results in a shortened life expectancy (1). Acute heart failure resulting in hospitalization is a significant cause of morbidity and mortality. With the increase in the severity of the disease and rapid advances in the treatment of heart failure, these patients are frequently hospitalized and monitored in intensive care. (2) Five years after diagnosis, mortality can be up to 67%. Additionally, it is known that patients with heart failure are hospitalized on average once a year after diagnosis. (3) In a multicenter study, it constituted 14% of 3000 cardiac patients admitted to intensive care units. Additionally, due to longer ICU stays, these patients accounted for 33% of total inpatient days. An increasing number of heart failure patients require intensive care due to respiratory failure, regardless of left ventricular ejection fraction. Heart failure accounts for approximately one-third of patient days in intensive care units, and this burden is increasing. This shows that attention should be paid to the quality of care for patients requiring critical care. (2) Multidisciplinary programs have been implemented to deal with the high prevalence. However, the optimal follow-up frequency is unknown. Therefore, some tools are needed to improve patient prognosis (3). Neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker whose values in both urine and plasma have been associated with acute kidney injury (AKI). Although NGAL is an early specific biomarker for AKI, it has not yet come into routine use, but is frequently used in clinical and experimental studies (4). Venous load ultrasonography score (VExUS) is a new systemic congestion scoring method based on inferior vena cava dilation and pulsed wave Doppler (PW-Doppler) morphology of the hepatic, portal and renal veins. It has been proposed as a score to assess systemic congestion.
The goal of this study is to quantitatively assess renal microcirculation changes by contrast-enhanced ultrasound and to obtain systemic hemodynamic information by ultrasound Doppler at the same time, to analyze the relationship between renal microcirculation changes and systemic hemodynamic changes, and to explore its predictive value in renal function recovery in patients with critical acute kidney injury. The main questions it aims to answer are: 1. To explore the quantitative parameters of contrast-enhanced ultrasound which can reflect the changes of renal microcirculation. 2. To explore the relationship between renal microcirculation and systemic hemodynamics. 3. To explore the value of renal microflow changes quantitatively evaluated by contrast-enhanced ultrasound in predicting renal function recovery.
This study investigates the association between post-reperfusion (neohepatic) ALBI scores and post-LT renal outcomes in living-donor LT (LDLT) recipients.
CDK4/6 inhibitors have led to an improvement of both progression free survival (PFS) and overall survival (OS) in patients with advanced estrogen positive (ER+)/HER2- breast cancer when applied in the first or second line of treatment. Despite the advantages of CDK4/6 inhibitors, these medications can lead to adverse effects. One of the adverse events observed across all types of CDK4/6 inhibitors is an elevation in creatinine levels. An elevation in plasma creatinine during treatment with abemaciclib is not always indicative of a reduction in renal function; it can also be attributed to the inhibition of active tubular secretion of creatinine. This phenomenon is known as pseudo acute kidney injury (pseudo-AKI). The incidence of pseudo-AKI in patients using CDK4/6 inhibitors is currently unknown. A method to distinguish pseudo-AKI from AKI is measuring the level of an alternative filtration marker in blood, for example cystatin C. Cystatin C is also filtered at the glomerulus but not secreted intro the renal tubulus or reabsorbed into the bloodstream. Also, there is no affection by muscle mass or diet. In this study the investigators will explore the incidence of both AKI and pseudo-AKI in patients who are treated with CDK4/6 inhibitor treatment by assessing both creatinine and cystatin C in plasma.
This prospective clinical trial aimed to assess the usefulness of the usage of a vacuum mattress during laparoscopic sleeve gastrectomy (LSG) in the reduction of levels of rhabdomyolysis markers (myoglobin, creatine kinase, creatinine) and incidence of RML and AKI in the postoperative period. Method Patients A prospective clinical trial has been conducted between January 2015 and December 2022 in a tertiary referral University Hospital (Krakow, Poland). It is designed as a single-center, prospective trial with two intervention arms. During the study, we specified 3 periods: - January 2015 - December 2016 - only standard mattresses were used - January 2017 - December 2019 - both types of mattresses were used - January 2020 - December 2022 - only vacuum mattresses were used Participants Patients aged ≥18 were qualified for LSG due to obesity and divided The first group (Vacuum Mattress group) are those laid on vacuum mattresses during the surgery. The control group consisted of patients for whom a standard operating mattress was used during the surgery. Patients with preoperative chronic renal failure were excluded from the study. Other exclusion criteria were perioperative complications which required postoperative hospitalization at the Intensive Care Unit and Compliance with Enhanced Recovery After Bariatric Surgery (ERABS) Protocol < 85%. Procedures and perioperative care All patients underwent LSG. Patients were operated in the beach chair position. In the study group, the patient was laid on vacuum mattresses during the surgery. In the case of control group patients, a standard operating mattress was used during the surgery. Perioperative care for all patients was in accordance with the ERABS protocol adopted in our center[]. Blood samples were collected on the first postoperative to measure RML markers (myoglobin, creatine kinase, creatinine). Symptoms of RML, AKI, and other complications were monitored for 30 days after surgery. End Point Criteria The primary endpoint is the incidence of postoperative AKI or biochemical or clinical diagnosis of RML which required additional treatment. Secondary endpoints is the concentrations of RML markers (myoglobin, creatine kinase, creatinine) on the first postoperative day
