RESUMO

To assess the effect of nesiritide on the endothelial function of iliac arteries following endothelia trauma. Right iliac artery trauma was created with a balloon catheter. Ten rabbits were treated with a 4-week subcutaneous injection of nesiritide at a fixed daily dose of 0.1mg/kg. Ten rabbits received daily normal saline injection. Plasma endothelin 1 (ET-1), nitric oxide (NO), and Von Willebrand Factor (vWF) were measured before and after the therapies. Tissue proliferating cell nuclear antigen (PCNA) was measured after the treatment. After the treatment, in the therapeutic group, the area under internal elastic membrane and the residual lumen area were higher than in the normal saline group (P <0.05). The plasma levels of ET-1 (91.6±6.8 vs 114.9±6.3 ng/L, P =0.001), vWF (134.6±10.8% vs 188.8±10.4%, P =0.001) and the ratio of PCNA positive expression (11.7±4.2% vs 36.2±11.4%, P =0.005) in the therapeutic group was lower than in the normal saline group, while the plasma levels of NO was higher (89.7±9.3 vs 43.5±5.3 µmol/L, P =0.001). Nesiritide inhibited remodeling of rabbit iliac artery following endothelial trauma. The inhibition of vascular remodeling may be related to the alleviated endothelial dysfunction and reduced expression of tissue proliferating cell nuclear antigen

RESUMO

We evaluated clinical factors associated with early central venous catheter (CVC) removal in cancer patients with candidaemia who survived >3 days after the index blood culture. This was a retrospective cohort study from a previous candidaemia database conducted between January 2001 and June 2005. Eligible patients were those whose catheters were removed. Those who died in the first 72 h were excluded. Early CVC removal was defined as withdrawal in the first 72 h. We enrolled 164 patients with a 10.4% mortality rate. Multivariate analysis showed temporary non-tunnelled catheter type (odds ratio 5.06; 95% confidence interval 2.16-11.83) as the only variable associated with early removal. Among the 84 episodes judged not catheter-related, 52 CVCs were removed due to the need for further cancer treatment. No differences in mortality were seen among patients with early or late catheter removal. Stratified analysis showed a survival benefit (p = 0.04) of early removal among patients with a Karnofsky performance status score >60. The study shows a propensity to immediately remove short-term catheters and a tendency for early removal in patients undergoing active cancer treatment. There was no benefit of early catheter removal with regard to overall mortality. The favourable impact of early over late removal on survival among patients without significant illness merits further investigation.
