Abstract Background. Postoperative acute kidney injury (PO-AKI) is a leading cause of short- and long-term morbidity and mortality, as well as progression to chronic kidney disease (CKD). The aim of this study was to explore the physicians’ attitude toward use of serum creatinine (sCr) for identification of patients at risk for PO-AKI and patients who should be reassessed in the long-term for progression toward CKD. We also evaluated the incidence and risk factors associated with PO-AKI and renal function deterioration in patients undergoing major surgery for malignant disease.Methods. Adult oncological patients who underwent major abdominal surgery from November 2016 to February 2017 were considered for this single centre, observational retrospective study. Routinely available sCr values were used to define AKI in the first three postoperative days. Long-term kidney dysfunction (LT-KDys) was defined as a reduction in the estimated glomerular filtration rate by more than 10 ml/min/m2 at 12 months postoperatively. A questionnaire was administered to 125 physicians caring for the enrolled patients to collect information on local attitudes regarding use of sCr perioperatively and its relationship with PO-AKI.Results. A total of 423 patients were observed. sCr was not available in 59 patients (13.9%); the remaining 364 (86.1%) had at least one sCr value measured to allow for detection of postoperative kidney impairment. Among these, PO-AKI was diagnosed in 8.2% of cases. Of the 334 patients who had a sCr result available at 12-month follow up, 56 (16.8%) developed LT-KDys. Data on long-term kidney function were not available for 21% of patients. Interestingly, 33 of 423 patients (7.8%) did not have a sCr result available in the immediate postoperative period or long-term. All the physicians who participated in the survey (83 out of 125) recognised that postoperative assessment of sCr is required after major oncological abdominal surgery, particularly in those patients at high-risk for PO-AKI and LT-KDys.Conclusion. PO-AKI after major surgery for malignant disease is common but clinical practice of measuring sCr is variable. As a result, the exact incidence of PO-AKI and long-term renal prognosis are unclear, including in high-risk patients.Trial registration. Retrospectively registered in Clinicaltrialgov NCT04341974

AbstractPostoperative acute kidney injury (PO-AKI) is a common complication of major surgery that is strongly associated with short-term surgical complications and long-term adverse outcomes, including increased risk of chronic kidney disease, cardiovascular events and death. Risk factors for PO-AKI include older age and comorbid diseases such as chronic kidney disease and diabetes mellitus. PO-AKI is best defined as AKI occurring within 7 days of an operative intervention using the Kidney Disease Improving Global Outcomes (KDIGO) definition of AKI; however, additional prognostic information may be gained from detailed clinical assessment and other diagnostic investigations in the form of a focused kidney health assessment (KHA). Prevention of PO-AKI is largely based on identification of high baseline risk, monitoring and reduction of nephrotoxic insults, whereas treatment involves the application of a bundle of interventions to avoid secondary kidney injury and mitigate the severity of AKI. As PO-AKI is strongly associated with long-term adverse outcomes, some form of follow-up KHA is essential; however, the form and location of this will be dictated by the nature and severity of the AKI. In this Consensus Statement, we provide graded recommendations for AKI after non-cardiac surgery and highlight priorities for future research.

Abstract Background and Aims Gut microbiota is considered an important factor affecting oxalate handling in the intestine. It has been demonstrated that intestinal oxalate secretion provides a complementary route of excretion, and it becomes more evident when kidney function declines. A diversity of gut oxalate-degrading bacteria (ODB) has been hypothesized to play a role in this process. However, there is a general lack of research on the long-term effects of acute kidney injury (AKI) on ODB and their total oxalate-degrading activity (ODA) in fecal microbiota. In this study, we evaluated whether renal dysfunction could affect intestinal ODB and their total ODA in a rat model of glycerol-induced AKI. Method The Male Wistar rats (200-300 g, n=20) on oxalate-free diet were randomly divided into 2 groups. After 24-h of water deprivation, Group 1 (n=10) received an intramuscular injection of 50% glycerol (10 ml/kg of body weight), and Group 2 (n=10) served as control. The numbers of ODB (incubated in a highly selective Oxalate Medium and determined using culture method) and total fecal ODA were measured after injection on days 7 and 70. The method of redoximetric titration with a KMnO4 solution was adopted to evaluate total ODA in fecal microbiota; the results were expressed as % of oxalate degradation per 0.01 g of feces. Renal injury was assessed by histopathological examination, serum creatinine and daily proteinuria levels after removing the animals from the experiment on day 70. Cortical interstitial fibrosis was measured by computerized image analysis on sections stained with picrosirius red. The median (Me) and the interquartile ranges (Q25; Q75) were calculated and compared using the nonparametric Mann-Whitney test. The Spearman correlation coefficient was used to evaluate association between the examined parameters. Results The obtained results demonstrated: 1) after glycerol injection on day 7, no differences were found in the numbers of ODB and total fecal ODA between the experimental and control groups: 5.9 (5.4-6.0) vs 6.0 (5.4-6.4) CFU/g, p=0.65 and 2.0 (0.1-5.0) vs 2.5 (2.0-9.0) %/0.01g, p=0.24, respectively; 2) after AKI initiation on day 70, the numbers of ODB and total fecal ODA were significantly lower in Group I compared with control Group II (Fig. 1); 3) the higher percentage of renal interstitial fibrosis was, the higher total fecal ODA occurred in the experimental rats (Fig. 2). In addition, the number of ODB in feces in Group 1 had an inverse association with serum creatinine (r=-0.52, p=0.006) and 24-h proteinuria levels (r=-0.86, p<0.0001). Conclusion AKI had the long-term negative effects on the quantitative and qualitative characteristics of ODB in fecal microbiota in rats. Moreover, the results of our study confirmed an increasing trend in total fecal ODA according to the aggravation of renal interstitial fibrosis in rats.

Abstract Primary Subject area Neonatal-Perinatal Medicine Background Infants undergoing abdominal surgery, particularly those born preterm, are at risk of postoperative fluid overload and acute kidney injury due to immature cardiac and renal functions, which could contribute to increased morbidity and mortality. Objectives The purpose of this study was to evaluate the burden of fluid overload and acute kidney injury among newborns undergoing abdominal surgery and the association with adverse neonatal outcomes. Design/Methods Newborns who had undergone laparotomy from January 2017 to June 2019 admitted to a tertiary level Neonatal Intensive Care Unit were included in this retrospective cohort study. Fluid overload was assessed by the maximum percentage change in body weight and the difference between actual and prescribed fluid intake post-operatively. Acute kidney injury was defined as an increase in serum creatinine >1.5 times of baseline or >26 mmol/L, or oliguria (< 0 .5mL/kg/hr over 24-hour). Results There were 60 eligible infants with medians [IQR] gestational age (GA) and birth weight being 29 weeks [25–36] and 1240 grams [721–2871], respectively. Indications for laparotomy included small bowel obstruction (45%), necrotizing enterocolitis (23%), and large bowel obstruction (11.7%). In the first three post-operative days, 24/60 (40%) required inotropes, 5/59 (8.5%) had hyponatremia (<130 mmol/L), and 15/31(48.4%) developed hypoalbuminemia (<20 g/L). 52/60 (86.7%) infants had serum creatinine measured and 4 (6.7%) fulfilled our AKI criteria. The median of actual fluid intake was significantly higher than the prescribed fluid intake in the first 7 post-operative days (p<0.01) [Figure 1]. Medians [IQR] of maximum % change of body weight within the first 3- and 7-days post operation were 6 [3–13] and 11 [5 –17], respectively. While we did not identify any associations between post-operative fluid overload and mortality/bronchopulmonary dysplasia in this cohort, we found that every 1% increase in weight gain within the first 3 days post-operation were associated with an increase in 0.6 day of invasive ventilator support (p=0.012) [Figure 2]. Such correlation still exists after adjusting for GA (p=0.033). Conclusion In our cohort of newborns undergoing abdominal surgery, weight gain within the first three post-operative days was associated with an increase in duration of invasive ventilator support. Fluid overload does not seem to be associated with acute kidney injury. Careful attention to intra and early postoperative fluid balance may play an important role in optimizing outcomes of newborns undergoing abdominal surgery.

Background. Transcatheter aortic valve implantation (TAVI) is widely used in high risk patients (pts) with aortic stenosis. Underlying chronic kidney disease implicates a high risk of postprocedural acute kidney injury (AKI). We analyzed its occurrence, impact on hospital stay, and mortality.Methods. 150 consecutive pts underwent TAVI in our institution (mean age81 ± 7years; logistic EuroSCORE24 ± 15%). AKI definition was a creatinine rise of26.5 μmol/L or more within 48 hours postprocedural. Ten patients on chronic hemodialysis were excluded.Results. AKI occurred in 28 pts (20%). Baseline creatinine was higher in AKI pts (126.4 ± 59.2 μmol/L versus 108.7 ± 45.1 μmol/L,P=0.09). Contrast media use was distributed evenly. Both, 30-day mortality (29% versus 7%,P<0.0001) and long-term mortality (43% versus 18%,P<0.0001) were higher; hospital stay was longer in AKI pts (20 ± 12 versus 15 ± 10 days,P=0.03). Predicted renal failure calculated STS Score was similar (8.0 ± 5.0% [AKI] versus 7.1 ± 4.0% [non-AKI],P=0.32) and estimated lower renal failure rates than observed.Conclusion. AKI remains a frequent complication with increased mortality in TAVI pts. Careful identification of risk factors and development of more suitable risk scores are essential.
