RESUMEN
OBJECTIVES: High triglycerides and low high density lipoprotein cholesterol are important cardiovascular risk factors. Triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C) has been reported to be useful in predicting cardiovascular disease. Brachial-ankle pulse wave velocity (baPWV) is a valid and reproducible measurement by which to assess arterial stiffness and a surrogate marker of atherosclerosis. However, there is limited evidence about the relationship between them. Therefore, we tested the hypotheses that TG/HDL-C is associated with baPWV in healthy individuals. METHODS: Fasting lipid profiles, baPWV and clinical data were measured in 1498 apparently healthy, medication-free subjects (926 men, 572 women) who participated in a routine health screening from 2011 to 2013. Participants were stratified into quartiles of TG/HDL-C ratio. BaPWV > 1400 cm/s was defined as abnormal baPWV, Multivariable logistic regression was used to identify associations of TG/HDL-C quartiles and baPWV, after adjusting for the presence of conventional cardiovascular risk factors. RESULTS: In both genders, we observed positive relationships between TG/HDL-C quartiles and BMI, systolic BP, diastolic BP, fasting glucose, total cholesterol, LDL-C, triglycerides, uric acid, and percentages of high baPWV. Multivariable logistic regression revealed that baPWV abnormality OR value of the highest TG/HDL-C quartiles was 1.91 (95% CI: 1.11-3.30, P < 0.05) and 2.91 (95% CI: 1.02-8.30, P < 0.05) in male and female after adjusting for age, systolic BP, diastolic BP, BMI, fasting plasma glucose, LDL-C, uric acid and estimated glomerular filtration rate when compared with the lowest TG/HDL-C quartiles. CONCLUSION: Increased TG/HDL-C was independently associated with baPWV abnormality in apparently healthy individuals.
RESUMEN
UNLABELLED: ⦠OBJECTIVES: We aimed to prospectively compare the incidence of catheter-related complications and catheter survival for straight (SCs) and coiled (CCs) Tenckhoff catheters in peritoneal dialysis (PD) patients. ⦠METHODS: This open prospective randomized trial recruited 189 PD patients with end-stage renal disease from the department of nephrology, The First Affiliated Hospital of Sun Yat-sen University from 6 November 2007 to 27 August 2008. The patients were randomized to a SC (n = 99) or a CC (n = 90) and were then followed for 2 years. All catheter placements were performed by two designated experienced nephrologists who used a standardized institutional placement protocol. The primary study outcomes were catheter-related complications and catheter survival at 1 and 2 years. ⦠RESULTS: We observed no significant differences in clinical and demographic characteristics between the groups at baseline. The overall incidence of catheter dysfunction was higher in the CC group than in the SC group (17.8% vs 7.1%, p = 0.03), and most of the events occurred 4 weeks or more after the catheters were implanted. Catheter tip migration and omental wrapping were the most common causes of catheter dysfunction. Surgical catheter rescue was more common in patients with CCs than in patients with SCs (9 vs 3 patients respectively, p = 0.05). No significant differences were observed in other catheter-related complications, including dialysate leaks, hernias, and PD-related infections (peritonitis, exit-site, and tunnel infections). Catheter survival rates in the SC and CC groups were similar at 1 year (96.7% ± 1.9% vs 96.5% ± 2.0%, p = 0.98) and at 2 years (95.3% ± 2.3% vs 92.4% ± 3.6%, p = 0.76). ⦠CONCLUSIONS: The incidence of PD catheter-related complications is probably higher with CCs than with SCs. The results of our study suggest that a SC is the better option to reduce subsequent catheter complications.
