Postoperative acute renal failure is a major cause of morbidity and mortality in colon and rectal surgery. Our objective was to identify preoperative risk factors that predispose patients to postoperative renal failure and renal insufficiency, and subsequently develop a risk calculator. Using the National Surgical Quality Improvement Program Participant Use Files database, all patients who underwent colorectal surgery in 2009 were selected (n = 21,720). We identified renal complications during the 30-day period after surgery...

Depression, anxiety, posttraumatic stress disorder (PTSD), and substance abuse are linked to higher rates of morbidity and mortality after various surgical procedures. Comparable data in general surgery are lacking. Records from 183 consecutive patients undergoing elective general surgery procedures at a single tertiary hospital were reviewed. Patients with depression, anxiety, PTSD, and substance abuse or any combination of these at the time of surgery were classified as having "active mental illness" (AMI)...

Vitamin D supplementation is universal for postmenopausal women, but not for elderly men, in whom osteoporosis is also commonly neglected. This study aimed to evaluate vitamin D deficiency and its association with secondary hyperparathyroidism, bone resorption, and bone density in Brazilian men. A total of 120 men, 20-93 years, were evaluated for serum calcium, phosphorus, creatinine, 25-hydroxyvitamin D (25(OH)D), parathyroid hormone, biochemical markers of bone resorption (carboxy-terminal telopeptide, carboxy-terminal peptide of type I collagen), and bone mineral density (dual-energy X-ray absorptiometry)...

Cadmium (CD), an environmental and industrial pollutant, generates reactive oxygen species (ROS) and NOS responsible for oxidative and nitrosative stress that can lead to nephrotoxic injury, including proximal tubule and glomerulus dysfunction. Sinapic acid (SA) has been found to possess potent antioxidant and anti-inflammatory effects in vitro and in vivo. We aimed to examine the nephroprotective, anti-oxidant, anti-inflammatory, and anti-apoptotic effects of SA against CD-induced nephrotoxicity and its underlying mechanism...

The definition of biological donor organ age rather than chronological age seems obvious for the establishment of a valid pre-transplant risk assessment. Therefore, we studied gene expression for candidate markers in 60 zero-hour kidney biopsies. Compared with 29 younger donors under age 55, 31 elderly donors age 55 and older had significant mRNA expression for immunoproteasome subunits (PSMB8, PSMB9 and PSMB10), HLA-DRB, and transcripts of the activating cytotoxicity receptor NKG2D. Gene expression was validated in an independent donor cohort consisting of 37 kidneys from donors 30 years and under (Group I), 75 kidneys from donors age 31-54 years (Group II) and 75 kidneys from donors age 55 and older (Group III)...

In the absence of uncontrolled hypertension or renal insufficiency, many consider the perinatal outcomes in pregnant women with nephrotic syndrome to be good. To further investigate this we performed a retrospective chart review of women with biopsy-proven nephrotic syndrome due to primary glomerular disease during pregnancy at a single tertiary center. Our review determined characteristics, presentation, management, pathologic diagnoses, and associated renal and maternal-fetal outcomes of 19 individuals with 26 pregnancies and 26 offspring...

BACKGROUND: Intravenous saline is recommended in clinical practice guidelines as the cornerstone for preventing contrast-induced nephropathy in patients with compromised renal function. However, clinical-effectiveness and cost-effectiveness of this prophylactic hydration treatment in protecting renal function has not been adequately studied in the population targeted by the guidelines, against a group receiving no prophylaxis. This was the aim of the AMACING trial. METHODS: AMACING is a prospective, randomised, phase 3, parallel-group, open-label, non-inferiority trial of patients at risk of contrast-induced nephropathy according to current guidelines...

The association between urinary cadmium and diabetes risk remains controversial. PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang Data updated on 21 June 2016 were searched for eligible publications. Pooled odds ratio (OR) with 95% confidence interval (CI) of diabetes for highest versus lowest level of urinary cadmium was calculated by using fixed-effect model or random-effect model. Dose-response relationship between urinary cadmium and diabetes was estimated by restricted cubic spline...

BACKGROUND: The objective of this study was to investigate some biomarkers of renal function and blood pressure in children who had recovered from undernutrition. METHODS: This was cross-sectional, comparative study in which a convenience sample of children of both genders (n = 126; age range 6-16 years) treated at the Centre for Nutritional Recovery and Education (São Paulo, Brazil) was used. These children were classified into four groups for analysis: (1) children who were well nourished (control group; n = 50), (2) those showing stunted growth (stunted group; n = 22), (3) those who were underweight (underweight group; n = 23) and (4) those who had recovered from undernutrition (recovered group; n = 31)...

BACKGROUND: Residual renal function (RRF), defined as the ability of native kidneys to eliminate water and uremic toxins, is closely correlated with mortality and morbidity rates among patients receiving either peritoneal dialysis (PD) or hemodialysis (HD) via continuous clearance of middle-sized molecules and protein-bound solutes. Therefore, preserving RRF is considered to be one of the primary goals in managing patients with end-stage renal disease (ESRD). SUMMARY AND KEY MESSAGES: In this article, we provide a review on the understanding and management of RRF in patients on dialysis...

BACKGROUND: Acute cardiorenal syndrome (CRS) is a common clinical condition associated with adverse outcomes. Early identification of acute kidney injury in this setting remains challenging given that serum creatinine level is a marker of renal function and not kidney injury. SUMMARY: Several renal injury-related molecules are now available, which may help elucidate the complexities of the organ crosstalk, enabling more accurate risk stratification and effective interventions...

While the pathophysiology and clinical significance of arterial calcifications have been studied extensively, minimal focus has been placed on venous calcification deposition. In this study, we evaluated the association between calcium deposition in human saphenous vein (HSV), endothelial function, and patient demographic risk factors. Fifty-four HSV segments were collected at the time of coronary artery bypass graft (CABG) surgery. The presence or absence of calcium deposits was visualized using the Von Kossa staining method...

Rational: Pretargeted radionuclide therapy (PRIT) with the beta-emitting radionuclide (177)Lu is an attractive approach to treat CEA-expressing tumors. The therapeutic efficacy of PRIT could be improved by using alpha-emitting radionuclides such as (213)Bi. Herein, we report and compare the tumor targeting properties and therapeutic efficacy of (213)Bi and (177)Lu for PRIT of CEA-expressing xenografts, using the bispecific antibody TF2 (anti-CEA x anti-HSG) and the di-HSG-DOTA peptide IMP288. Methods: The in vitro binding characteristics of (213)Bi-IMP288 were compared with those of (177)Lu-IMP288...

OBJECTIVE: Patients with atherosclerotic cardiovascular disease (CVD) vary significantly in their risk of future CVD events; yet few clinical scores are available to aid assessment of risk. We sought to develop a score for use in primary care that estimates short-term CVD risk in these patients. METHODS: Adults aged <80 years with prior CVD were identified from a New Zealand primary care cohort study (PREDICT), and linked to national mortality, hospitalisation and dispensing databases...

BACKGROUND: In aging populations with an ever-growing burden of risk factors such as obesity, diabetes, and hypertension, chronic kidney disease (CKD) is on the rise. However, little is known about its exact prevalence among elderly adults, and often albuminuria is not included in the definition of CKD. Moreover, novel equations for the estimated glomerular filtration rate (eGFR) have recently emerged, which have not been applied comprehensively to older adults. Data on CKD awareness among the elderly are sparse...

Amphotericin B deoxycholate (ABD) is the best therapeutic agent available for the treatment of most systemic fungal infections. However, some untoward adverse effects such as nephrotoxicity may limit its appropriate therapeutic use. We conducted a randomized, controlled trial ofthe infusion of fat emulsion (Intralipid) shortly after the infusion of ABD to evaluate its effects on reducing ABD-associated nephrotoxicity. Our patient population was made up of 31 patients who were randomized into two groups: an intervention group (n = 16) and a control group (15 patients)...

BACKGROUND: Albuminuria in maintenance heart transplantation (HTx) is associated with poor renal response when switching to a calcineurin inhibitor (CNI)-lowered or free immunosuppressive regimen using everolimus (EVR), but the significance of albuminuria associated with EVR treatment after early CNI withdrawal in de novo HTx is unknown. METHODS: We tested if glomerular filtration rate (mGFR, measured by CrEDTA clearance) was associated with urine albumin/creatinine ratio (UACR) post-HTx in a subgroup of patients included in the SCHEDULE trial, where de novo HTx patients (n=115) were randomized to EVR with complete CNI elimination 7-11 weeks post-HTx or standard CNI immunosuppression...
