ABSTRACT
INTRODUCTION: Arteriovenous fistulas (AVFs) are the preferred form vascular access for hemodialysis (HD), as they have a low rate of complications and durable function. The aim of our investigation was to analyze the factors that might influence the function of AVFs. METHODS: Data were taken from the computerized patient record system in the Clinic of Urology and Nephrology, Clinical Center, Kragujevac, Serbia, for a 2-year period. We analyzed patients who had requested re-creation of AVFs as a secondary procedure. During this period 112 patients, 73 (65%) men and 39 (35%) women, had AVF thromboses. All relevant clinical and laboratory parameters that could affect the function and survival of AVF were evaluated. FINDINGS: In univariate logistic regression analysis, statistically significant predictors influencing the duration of the fistula were magnesium (P < 0.001), triglycerides (P = 0.041), smoking (P = 0.001), antiplatelet therapy (P < 0.001), and type of HD (bicarbonate vs. hemodiafiltration) (P < 0.001). In the multiple logistic regression model, high concentrations of magnesium (B = 7.434; P < 0.001) and antiplatelet therapy (B - 1.042; P = 0.04) were significantly associated with the length of AVF function. DISCUSSION: After successful establishment of an AVF, there is a compelling need to maintain fistula patency. Factors that affect functioning of the AVFs are presently under intense scrutiny. According to our results, some clinical factors may determine long term fistula duration, such as concentration of the magnesium and antiplatelet therapy.

Psoriasis severity varies by body region, with each affected region having a different impact on patient quality of life (QoL). The aim of this study was to assess the impact of changes in the Psoriasis Area and Severity Index (PASI) scores by body region on QoL in patients with psoriasis after treatment. A total of 100 patients with psoriasis were recruited to the study. All patients completed the generic EuroQol-5D instrument and two specific QoL measures, Dermatology Life Quality Index (DLQI) and Psoriasis Disability Index (PDI) at the beginning of the study, and 50 patients successfully completed the same questionnaires four weeks after the end of the treatment. Clinical severity was assessed using PASI total score and PASI body region (head, trunk, arms, and legs) scores. QoL improved after treatment, and PASI improvements on visible body regions (head, legs, and arms) showed significant correlation with the most sub-areas of the Visual Analog Scale (EQ VAS), DLQI, and PDI. Multiple linear regression analysis revealed that PASI improvement (particularly on the head), sex, age, and disease duration were predictors of QoL score changes for most domains of the three instruments. Improvement of psoriasis in visible body regions has an appreciable influence on QoL improvement, and may positively affect treatment success in patients with psoriasis.

Cannulation technique has the potential to impact arteriovenous fistula (AVF) function. The aim of this research was to determine the impact of cannulation technique on the length of the functioning AVFs in older adult patients on hemodialysis. The study included 110 participants with fistula thrombosis who had used area technique or rope ladder technique. Biochemical parameters, gender, demographic, and clinical variables were determined. Patients who used the area cannulation technique differed significantly from patients using the rope ladder technique with regard to duration of hemodialysis (p < 0.001), outcome of the AVF revision (p = 0.045), and positioning of the anastomosis (p = 0.013). The group that used the area cannulation technique had a longer duration of hemodialysis, proximal anastomoses, and more successful revisions of AVFs.

PURPOSE: The aim was to examine the predictors of improvement of quality of life after 2 years of coronary artery bypass grafting (CABG). METHODS: In all, 208 patients who underwent the elective CABG at the Institute for Cardiovascular Diseases Dedinje in Belgrade were contacted and examined 2 years after the surgery. All patients completed Nottingham Health Profile Questionnaire part one. RESULTS: Two years after CABG, quality of life (QOL) in patients was significantly improved in all sections compared to preoperative period. Independent predictors of QOL improvement after 2 years of CABG were found to be serious angina under sections of physical mobility [p = 0.003, odds ratio (OR) = 1.76, 95% confidence interval (CI) 1.21-2.55], energy (p = 0.01, OR = 1.63, 95% CI: 1.11-2.38), sleep (p = 0.005, OR = 1.65, 95% CI: 1.16-2.35), pain (p <0.001, OR = 2.43, 95% CI: 1.57-3.77), absence of hereditary load in energy section (p = 0.002, OR = 0.35, 95% CI: 0.18-0.68), male sex in the sleep section (p = 0.03, OR = 0.43, 95% CI: 0.20-0.93), and absence of diabetes in pain section (p = 0.006, OR = 0.27, 95% CI: 0.10-0.68). CONCLUSION: Predictors of improvement of QOL after 2 years of CABG are serious angina, absence of hereditary load, male sex, and absence of diabetes.
