Hypoalbuminemia in peritoneal dialysis patients
This study aimed to determine the factors that were associated with hypoalbuminemia in peritoneal dialysis (PD) patients. End-stage renal disease patients who had received PD at the National Taiwan University Hospital for more than three months were included and divided into two groups. Patients who had mean serum albumin levels greater or equal to 3.5g/dL were allocated to Group 1, while those who had mean serum albumin levels less than 3.5g/dL were allocated to Group 2. Demographic characteristics, clinical parameters and laboratory data were then compared between the two groups. Logistic regression was also performed to identify the factors that were associated with hypoalbuminemia. There were 359 patients (mean age 54.3 years, male 46.5%) included. Group 2 patients (10.3%) were older (P=0.0536), had lower body mass index (P=0.0008), lower total Kt/V (P=0.0060), and lower levels of hemoglobin (P=0.0268), blood urea nitrogen (P=0.0501), creatinine (P<0.0001), triglyceride (P=0.0014), potassium (P=0.0028), phosphorus (P=0.0036), but higher levels of C-reactive protein (P=0.0194). More Group 2 patients had high or high-average peritoneal equilibration test (PET) (P=0.0199). Using logistic regression, factors that were found to be associated with hypoalbuminemia were total Kt/V (P=0.0015), hemoglobin (P=0.0019), creatinine (P<0.0001), triglyceride (P=0.0060), and potassium (P=0.0126). In conclusion, hypoalbuminemia in our PD patients was associated with total Kt/V as well as levels of hemoglobin, creatinine, triglyceride, and potassium
Advanced age affects the outcome-predictive power of RIFLE classification in geriatric patients with acute kidney injury
The RIFLE (risk, injury, failure, loss, and end-stage) classification is widely used to gauge the severity of acute kidney injury, but its efficacy has not been formally tested in geriatric patients. To correct this we conducted a prospective observational study in a multicenter cohort of 3931 elderly patients (65 years of age or older) who developed acute kidney injury in accordance with the RIFLE creatinine criteria after major surgery. We studied the predictive power of the RIFLE classification for in-hospital mortality and investigated the potential interaction between age and RIFLE classification. In general, the survivors were significantly younger than the nonsurvivors and more likely to have hypertension. In patients 76 years of age and younger, RIFLE-R, -I, or -F classifications were significantly associated with increased hospital mortality in a stepwise manner. There was no significant difference, however, in hospital mortality in those over 76 years of age between patients with RIFLE-R and RIFLE-I, although RIFLE-F patients had significantly higher mortality than both groups. Thus, the less severe categorizations of acute kidney injury per RIFLE classification may not truly reflect the adverse impact on elderly patients
Late initiation of renal replacement therapy is associated with worse outcomes in acute kidney injury after major abdominal surgery
Introduction Abdominal surgery is probably associated with more likelihood to cause acute kidney injury (AKI). The aim of this study was to evaluate whether early or late start of renal replacement therapy (RRT) defined by simplified RIFLE (sRIFLE) classification in AKI patients after major abdominal surgery will affect outcome. Methods A multicenter prospective observational study based on the NSARF ( National Taiwan University Surgical ICU Associated Renal Failure) Study Group database. 98 patients (41 female, mean age 66.4 +/- 13.9 years) who underwent acute RRT according to local indications for post-major abdominal surgery AKI between 1 January, 2002 and 31 December, 2005 were enrolled The demographic data, comorbid diseases, types of surgery and RRT, as well as the indications for RRT were documented. The patients were divided into early dialysis (sRIFLE-0 or Risk) and late dialysis (LD, sRIFLE -Injury or Failure) groups. Then we measured and recorded patients' outcome including in-hospital mortality and RRT wean-off until 30 June, 2006. Results The in-hospital mortality was compared as endpoint. Fifty-seven patients (58.2%) died during hospitalization. LD (hazard ratio (HR) 1.846; P = 0.027), old age (HR 2.090; P = 0.010), cardiac failure (HR 4.620; P < 0.001), pre-RRT SOFA score (HR 1.152; P < 0.001) were independent indicators for in-hospital mortality. Conclusions The findings of this study support earlier initiation of acute RRT, and also underscore the importance of predicting prognoses of major abdominal surgical patients with AKI by using RIFLE classification
Safety Issues of Long-Term Glucose Load in Patients on Peritoneal Dialysis—A 7-Year Cohort Study
BACKGROUND: Effects of long-term glucose load on peritoneal dialysis (PD) patient safety and outcomes have seldom been reported. This study demonstrates the influence of long-term glucose load on patient and technique survival. METHODS: We surveyed 173 incident PD patients. Long-term glucose load was evaluated by calculating the average dialysate glucose concentration since initiation of PD. Risk factors were assessed by fitting Cox's models with repeatedly measured time-dependent covariates. RESULTS: We noted that older age, higher glucose concentration, and lower residual renal function (RRF) were significantly associated with a worse patient survival. We found that female gender, absence of diabetes, lower glucose concentration, use of icodextrin, higher serum high density lipoprotein cholesterol, and higher RRF were significantly associated with a better technique survival. CONCLUSIONS: Long-term glucose load predicted mortality and technique failure in chronic PD patients. These findings emphasize the importance of minimizing glucose load in PD patients
Impact of timing of renal replacement therapy initiation on outcome of septic acute kidney injury
A Potential Fungal Probiotic Aureobasidium melanogenum CK-CsC for the Western Honey Bee, Apis mellifera
Aureobasidium melanogenum has been used as an animal feed additive for improving thehealth of pets, however, it has not yet been applied in honey bees. Here, a fungal strain CK-CsC isolated from bee bread pollen, was identified as A. melanogenum. Following characterizing CK-CsC fermentation broth, the 4-days fermentation broth (SYM medium or bee pollen) of the CK-CsC was used to feed newly emerged adult honey bees in cages under laboratory-controlled conditions for analysis of survival, gene expression of nutrient and antibacterial peptide, and gut microbiota of honey bees. It was found that the CK–CsC fermentation broth (SYM medium or bee pollen) is nontoxic to honey bees, and can regularly increase nutrient gene expression of honey bees. However, significant mortality of bees was observed after bees were fed on the supernatant liquid of the fermentation broth. Notably, this mortality can be lowered by the simultaneous consumption of bee pollen. The honey bees that were fed bee pollen exhibited more γ-Proteobacteria, Bacteriodetes, and Actinobacteria in their gut flora than did the honey bees fed only crude supernatant liquid extract. These findings indicate that A. melanogenum CK–CsC has high potential as a bee probiotic when it was fermented with bee pollen
Is prophylactic nasogastric tube decompression necessary in patients undergoing laparoscopic adrenalectomy for unilateral benign adrenal tumor
Background/Purpose: This study aims to investigate the safety and feasibility of laparoscopic adrenalectomy for benign adrenal tumor without peri-operative NGT decompression. Methods: From July 2010 to March 2014, 82 consecutive patients with benign unilateral adrenal tumor underwent elective laparoscopic adrenalectomy by a single surgeon were recruited for this study. We compared the clinico-demographic profile, estimated blood loss, operative time, time to full diet, time to ambulate, the length of hospital staying, analgesics use and complications between two groups stratified by the use of NGT. Results: There were no significant differences in the clinico-demographic profile of the two groups, including age, laterality, body mass index, gender, ASA classification, tumor diameter and histologic types between two groups. Peri-operative parameters were similar between NGT and Non-NGT groups (estimated blood loss, 55.85 vs. 54.4 ml; operative time, 110.3 vs. 112.3 min; p > 0.05) The post-operative outcome of interests, including days to full oral intake (3.32 vs. 3.34 days), days to ambulate (2.07 vs. 2.10 days), hospital stay (4.32 vs. 4.34 days), and analgesics use (6.00 vs. 5.83 mg; all p > 0.05) showed no significant difference between NGT and non-NGT group. Conclusion: Laparoscopic adrenalectomy in patients with benign unilateral adrenal tumor without the use of peri-operative nasogastric tube decompression is safe and feasible. Keywords: Nasogastric tube decompression, Outcomes, Laparoscopic adrenalectom

Metabolic Syndrome and Insulin Resistance as Risk Factors for Development of Chronic Kidney Disease and Rapid Decline in Renal Function in Elderly
Hyperuricemia Associated With Rapid Renal Function Decline in Elderly Taiwanese Subjects
Hyperuricemia is encountered frequently in patients with chronic kidney disease (CKD). We tested the hypothesis that uric acid influences glomerular filtration rate (GFR) and is associated with renal function decline in elderly Taiwanese subjects.
Methods: We enrolled 800 elderly Taiwanese subjects for a health checkup. Estimated GFR (eGFR) was measured using the Modification of Diet in Renal Disease Study equation. eGFR < 60 mL/min/1.73 m2 was used to analyze the prevalence and incidence of CKD. Significant renal function decline was defined as a decrease in eGFR of ≥ 3 mL/min/1.73 m2 per year.
Results: The prevalence of CKD was 18.0% in the elderly subjects. Mean serum uric acid level was 6.6 mg/dL in male and 5.6 mg/dL in female subjects, and eGFR was 71.7 mL/min/1.73 m2. Uric acid levels were associated independently and negatively with eGFR after adjusting for conventional factors of renal function decline. One hundred and sixty-two individuals (31.2%) had a significant decline in renal function. As uric acid level increased by 1 mg/dL, the odds of a significant eGFR decline increased by 1.208.
Conclusion: Serum uric acid level was associated with eGFR and decline in renal function in elderly Taiwanese subjects. Whether hypouricemic therapy could retard the progression of CKD deserves further in-depth study
