METHODS: Patient undergoing bariatric surgery from 2008 to 2015 who developed AKI within 60 days after surgery were studied. Patients on dialysis before surgery were excluded.
RESULTS: Out of 4722 patients, 42 patients (0.9%) developed early postoperative AKI after bariatric surgery of whom five had chronic kidney disease (CKD) preoperatively including CKD stage 3 (n = 2), stage 4 (n = 2), and stage 5 (n = 1). Etiologies of AKI included prerenal in 37 and renal in 5 patients. Nine patients (21%) underwent hemodialysis in early postoperative period for AKI. The median duration of follow-up was 28 months (interquartile range, 4-59). Of the 40 patients eligible for follow-up, 36 patients (90%) returned to their baseline renal function. However, four patients (10%) had worsening of renal function at follow-up.
CONCLUSIONS: The incidence of early postoperative AKI after bariatric surgery is about 1%. The most common causes of AKI after bariatric surgery are dehydration and infectious complications. In our series, 10% of patients who developed AKI in early postoperative period had worsening of renal function in long-term follow-up. In the absence of severe sepsis and severe underlying kidney dysfunction (CKD stages 4 and 5), full recovery is expected after postoperative AKI.
METHODS: This collaborative project will synthesize data and perform meta-analyses of observational studies conducted in Asia. Studies will be identified through a systematic literature search including abstracts, proceedings of meetings, electronic databases such as MEDLINE and EMBASE. Personal enquiry among collaborators and experts in the region will identify additional studies, or other data sources such as registries. Both cross-sectional and longitudinal studies that describe the prevalence of CKD and its complications will be included, as will longitudinal studies that describe important clinical outcomes for people with CKD. Individual participant data will be sought, where possible, from each of the studies included in the collaboration for baseline parameters and subsequent outcomes, in order to maximize flexibility and consistency of data analyses.
CONCLUSIONS: This study is an initiative offering a unique opportunity to obtain information about the prevalence and manifestations of CKD in Asia, as well as its risk factors. The ARC will also provide insights into important outcomes including progression of CKD, CKD complications, cardiovascular disease and death. These findings will improve our understanding of kidney disease in Asia, and thus help inform service provision, preventive care and further research across the region.
PATIENTS AND METHODS: Materials and methods: Based on autopsy materials, we conducted a morphological study of patients (n = 20) aged 45 to 55 years who were observed in cardiac and neurological hospitals for 5-7 years. We removed kidney, heart and aorta samples from patients. For the study, a histological and immunohistochemical methods were used.
RESULTS: Results and conclusions: Morphological study of vessels endothelium of kidneys, heart and aorta demonstrated that in the majority of observations intima underwentprofound pathological changes, manifested by different degrees of disorganization of endothelial lining and violations of structural and functional organization of the endotheliocytes, subendothelial layer, basal membrane. These pathological processes in all cases had similar features with the development of immune inflammation. Inflammatory infiltration was represented by macrophages, mast cells, plasma cells. Biological mediators of the presented cells can aggravate the damage to endothelial cells. Indirect signs of low ability to restore the structure of the vessel wall and endothelial lining may be a weak expression of the VEGF and bcl-2 vascular endothelial growth factor.
METHODS: We retrospectively reviewed infants with ARM who received surgery and were followed at the Sabah Women and Children's Hospital, Malaysia, from 1986 to 2010.
RESULTS: One hundred and twenty-two children with anorectal malformations were studied, after excluding 24 children with incomplete data. Three factors were significant as predictors of the presence of a urological anomaly: high ARM lesion (OR 3.12, 95%CI 1.1-8.9), the presence of genital abnormality (OR 2.95, 95%CI 1.10-7.91) and cloacal anomaly in girls (OR 8.27, 95% CI 1.91-35.6). The most common anomalies were vesicoureteric reflux, single kidney and neurogenic bladder. Chronic kidney disease (CKD) was noted in 5.7%, in children who had recurrent urinary tract infections, neurogenic bladder or complex renal tract pathology; end-stage renal failure was seen in only 0.8% of children with ARM.
CONCLUSION: Urological anomalies were seen in 23% of patients, but the overall incidence of CKD and end-stage renal disease is low. Early identification of infants with ARM at risk of renal failure may be important for renal survival.
CASE PRESENTATION: We report a successful elderly multigravid pregnancy, in a patient undergoing continuous ambulatory peritoneal dialysis (CAPD). Her pregnancy was detected early and she was closely managed by the nephrologist and obstetrician. She tolerated the same PD prescription throughout 36 weeks of pregnancy with daily ultrafiltration of 500-1500mls. Her blood pressure remained well controlled without the need of any antihypertensive medication. Her total Kt/V ranged from 1.93 to 2.73. Her blood parameters remained stable and she was electively admitted at 36 weeks for a trans-peritoneal lower segment caesarian section and bilateral tubal ligation.
CONCLUSIONS: At the age of 42, our case is the oldest reported successful pregnancy in a patient on peritoneal dialysis. With careful counselling and meticulous follow up, we have shown that woman in the early stage of end stage renal failure can successfully deliver a full term baby without any complications. Therefore, these women should not be discourage from conceiving even if they are in advanced maternal age for pregnancy.
METHOD: The 5D itch scale was translated from English into Urdu following translation guidelines for translation. Face and content validity was determined by a panel of experts and piloted. For retest, the Urdu version of the 5D itch scale was administered at baseline and two weeks.
RESULTS: A total of 50 participants with end stage renal disease were recruited, and of these, 64% were males. Exploratory factor analysis revealed that the 5D-IS had 2-factor loadings: "Pattern and activity" and "Distribution" with Kaiser-Mayer-Olkin (KMO) = 0.802, Bartlett's test of sphericity was significant (df = 28, p chronic kidney disease in Pakistan.
METHODS: The study comprised 106 chronic kidney disease (CKD) patients and 203 control subjects. Conventional ultrasound was performed to measure the kidney length and cortical thickness. SWE imaging was performed to measure renal parenchymal stiffness. Diagnostic performance of SWE and conventional ultrasound were correlated with serum creatinine, urea levels and eGFR.
RESULTS: Pearson's correlation coefficient revealed a negative correlation between YM measurements and eGFR (r = -0.576, p < 0.0001). Positive correlations between YM measurements and age (r = 0.321, p < 0.05), serum creatinine (r = 0.375, p < 0.0001) and urea (r = 0.287, p < 0.0001) were also observed. The area under the receiver operating characteristic curve for SWE (0.87) was superior to conventional ultrasound alone (0.35-0.37). The cut-off value of less or equal to 4.31 kPa suggested a non-diseased kidney (80.3% sensitivity, 79.5% specificity).
CONCLUSION: SWE was superior to renal length and cortical thickness in detecting CKD. A value of 4.31 kPa or less showed good accuracy in determining whether a kidney was diseased or not. Advances in knowledge: On SWE, CKD patients show greater renal parenchymal stiffness than non-CKD patients. Determining a cut-off value between normal and diseased renal parenchyma may help in early non-invasive detection and management of CKD.
