METHODS: POISE-2 was a blinded, randomized trial of patients having non-cardiac surgery. Patients were assigned to perioperative aspirin or placebo. The primary outcome was a composite of death or myocardial infarction at 30 days. Secondary outcomes included: vascular occlusive complications (a composite of amputation and peripheral arterial thrombosis) and major or life-threatening bleeding.
RESULTS: Of 10 010 patients in POISE-2, 603 underwent vascular surgery, 319 in the continuation and 284 in the initiation stratum. Some 272 patients had vascular surgery for occlusive disease and 265 had aneurysm surgery. The primary outcome occurred in 13·7 per cent of patients having aneurysm repair allocated to aspirin and 9·0 per cent who had placebo (hazard ratio (HR) 1·48, 95 per cent c.i. 0·71 to 3·09). Among patients who had surgery for occlusive vascular disease, 15·8 per cent allocated to aspirin and 13·6 per cent on placebo had the primary outcome (HR 1·16, 0·62 to 2·17). There was no interaction with the primary outcome for type of surgery (P = 0·294) or aspirin stratum (P = 0·623). There was no interaction for vascular occlusive complications (P = 0·413) or bleeding (P = 0·900) for vascular compared with non-vascular surgery.
CONCLUSION: This study suggests that the overall POISE-2 results apply to vascular surgery. Perioperative withdrawal of chronic aspirin therapy did not increase cardiovascular or vascular occlusive complications. Registration number: NCT01082874 ( http://www.clinicaltrials.gov).
METHODS: Incident HD patients without permanent vascular access encountered from January to December 2014 were included in this study. Patients were divided into 2 groups: Group 1 were encountered within 6 months prior to introduction of in-patient IPD bridging therapy in substitution of noncuffed catheter (NCC) insertion while awaiting maturation of permanent vascular access. Group 2 were encountered within 6 months after the introduction of this policy. The number of NCC and peritoneal dialysiscatheter insertion, along with catheter-related infections were evaluated during this period.
RESULTS: Approximately 450 patients were distributed in each group. We achieved 45% reduction in internal jugular catheter insertion from 322 to 180 catheters after policy change. This led to a significant drop in catheter-related blood stream infection (53%, P <0.001). On the other hand, 30% more peritoneal dialysiscatheter were inserted to accommodate our IPD bridging therapy.
CONCLUSIONS: The introduction of IPD as bridging therapy while awaiting maturation of permanent vascular access significantly reduced the utilization of NCC in incident HD patients and catherter-related blodstream infection. With this, it is our hope that it will contribute to the preservation of central vein patency.
METHODS: Renal registries reporting on patients starting RRT per million population for ESRD by PRD from 2005 to 2014, were identified by internet search and literature review. The average annual percentage change (AAPC) with a 95% confidence interval (CI) of the time trends was computed using Joinpoint regression.
RESULTS: There was a significant decrease in the incidence of RRT for ESRD due to diabetes mellitus (DM) in Europe (AAPC = -0.9; 95%CI -1.3; -0.5) and to hypertension/renal vascular disease (HT/RVD) in Australia (AAPC = -1.8; 95%CI -3.3; -0.3), Canada (AAPC = -2.9; 95%CI -4.4; -1.5) and Europe (AAPC = -1.1; 95%CI -2.1; -0.0). A decrease or stabilization was observed for glomerulonephritis in all regions and for autosomal dominant polycystic kidney disease (ADPKD) in all regions except for Malaysia and the Republic of Korea. An increase of 5.2-16.3% was observed for DM, HT/RVD and ADPKD in Malaysia and the Republic of Korea.
CONCLUSION: Large international differences exist in the trends in incidence of RRT by primary renal disease. Mapping of these international trends is the first step in defining the causes and successful preventative measures of CKD.
