It is concluded that presurgical infiltration of 0.25% bupivacaine in the surgical field is a useful method for decreasing postsurgical wound pain for up to 10 hours and analgesic consumption for up to 24 hours after laparoscopic gynecologic examination.

Levels of fibroblast growth factor (FGF) 23, a phosphatonin, are frequently elevated in patients with end-stage renal disease (ESRD) who are on maintenance hemodialysis (MHD). However, the role of FGF23 remains unclear because renal FGF receptor function might be impaired. The present cross-sectional study examines a cohort of patients (n = 196) on MHD who were not undergoing therapy with lipid-lowering drugs including sevelamer. Non-fasting venous blood samples were withdrawn before the hemodialysis (HD) session on the third day after the previous HD session to measure serum levels of albumin, calcium (Ca), phosphate (P), alkaline phosphatase, intact parathyroid hormone (PTH), total cholesterol (C), high-density lipoprotein (HDL)-C, low-density lipoprotein(LDL)-C, oxidative LDL-C, high-sensitivity C-reactive protein (HsCRP), interleukin-6 (IL-6), and FGF23. Nutritional status was assessed using the geriatric nutritional risk index (GNRI). Carotid intima-medial thickness (CIMT) was assessed using a B-mode ultrasound scanner. FGF23 was positively correlated with P, Ca(alb)xP product, and intact PTH, and inversely correlated with C and non-HDL-C. In the higher FGF23 tertile, levels of both non-HDL-C and C were significantly decreased and CIMT was less elevated compared to the lower FGF23 tertile. Multivariate analysis showed that the higher FGF23 tertile was independently associated with decreases in C (adjusted r(2) = 0.14) and non-HDL-C (adjusted r(2) = 0.20) levels and with a less-pronounced increase in CIMT (adjusted r(2) = 0.14). High FGF23 appears to be an independent biomarker of a decrease in C and non-HDL-C that is negatively associated with atherosclerosis in patients on MHD.

Background: Ultrapure dialysate (UD) might contribute to improvements in the morbidity and mortality of hemodialysis (HD) patients. However, it is unclear whether increasing dialysate purity affects chronic inflammation, oxidative stress, and lipid abnormalities. Methods: In a prospective cohort study, 126 patients undergoing maintenance HD using conventional dialysate (CD) with one endotoxin cut filter were assigned to either continuation of the same HD or HD using UD (more purified dialysate). At baseline and 6 months we measured lipids, high-sensitive (hs)CRP, oxidative LDL-cholesterol, and myeloperoxidase. Results: Serum myeloperoxidase and hsCRP levels in the UD group were significantly decreased at 6 months compared with the CD group. Multivariate analysis showed that decreases in non-HDL-cholesterol and ApoB at 6 months were independently correlated with changes in myeloperoxidase. Conclusion: Endotoxin-free UD can improve the chronic inflammatory status, oxidative stress, and lipid abnormalities, suggesting a possible contribution to reduced cardiovascular disease risk and ultimately to lowered mortality in HD patients.

Abstract. To clarify the involvement of 5-hydroxytryptamine (5-HT) in promotion of thrombogenesis in diabetes, we examined the inhibitory effect of sarpogrelate, a 5-HT 2A receptor antagonist, on thrombus formation in diabetic rats. In streptozotocin-induced diabetic rats, polyethylene tubeinduced thrombus formation was enhanced compared with that in normal rats. The thrombogenesis was inhibited by sarpogrelate; cilostazol, a PDE3 inhibitor; and aspirin, a COX inhibitor, by 75.8%, 42.3%, and 34.3%, respectively. The inhibition by sarpogrelate was more pronounced in diabetic rats than normal ones. High glucose and 5-HT increased the expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) and combination of both high glucose and 5-HT further potentiated the effect. Sarpogrelate but not aspirin inhibited the increase in VCAM-1 expression induced by high glucose and 5-HT. These findings suggest that 5-HT mediates the enhanced thrombogenesis in diabetes and suggests that a 5-HT 2A receptor antagonist may have novel therapeutic potential for the treatment of diabetic complications.

Background and objectives: Oxidized HDL (oxHDL) may behave as proinflammatory HDL because of reduced antiinflammatory capacity and is considered a risk factor for mortality in patients on maintenance hemodialysis (MHD). The study presented here assessed the effect of oxHDL on protein-energy wasting (PEW) in MHD patients.Design, setting, participants, & measurements: This prospective study examined a cohort of MHD patients (n ‫؍‬ 176) who were not taking lipid-lowering drugs. Blood samples were obtained to measure albumin, lipids, high-sensitivity C-reactive protein (hsCRP), oxidized LDL (oxLDL), and oxHDL. PEW was assessed by subjective global assessment (SGA) and geriatric nutritional risk index (GNRI). Measurements and assessment of nutritional status were followed up 1 year later.Results: OxHDL was significantly increased in patients with PEW at baseline. High oxHDL and high hsCRP were significantly associated with PEW, and receiver operating characteristic curves for oxHDL and hsCRP showed statistically similar accuracy for predicting SGA-positive status. According to multivariate regression models, high oxHDL had a significant influence on PEW in patients, particularly those with high hsCRP. Decreased changes in GNRI and high prevalence of SGA-positive status at 1 year were more common in patients with high oxHDL at baseline and 1 year later than in patients with low oxHDL at both time points.Conclusions: A high oxHDL state may be associated with PEW estimated by GNRI and SGA, particularly concomitant with inflammation in MHD patients.
