Are There Differences in Arteriovenous Fistulae Created for Hemodialysis between Nephrologists and Vascular Surgeons?

OBJECTIVE: Many studies have reported insufficient support from surgical services, resulting in nephrologists creating arteriovenous fistulas in many centers. The aim of this study was to compare risk factors of arteriovenous fistula dysfunction in patients whose fistulas were created by nephrologists versus vascular surgeons. METHODS: This was a retrospective, analytical study of interventions by nephrologists and vascular surgeons during a period of 15 years. Out of a total of 1,048 fistulas, 764 (72.9%) were created by nephrologists patients, while vascular surgeons were responsible for 284 (27.1%) fistulae. Laboratory, demographic, and clinical parameters which might affect functioning of these arteriovenous fistulae were analyzed. RESULTS: Patients whose arteriovenous fistula was formed by nephrologists differed significantly from those created by vascular surgeons in relation to the preventive character of the arteriovenous fistula (p = 0.011), lumen of the vein (p < 0.001) and systolic blood pressure (p = 0.047). Multivariate logistic regression of arteriovenous fistula dysfunction showed that risk factors were female gender (odds ratio [OR] = 1.56, 95% CI 1.16-2.07), whether the fistulae were created by vascular surgeons or nephrologists (OR = 1.38; 95% CI 1.01-1.89) and the site of the arteriovenous fistula (OR = 0.64; 95% CI 0.48-0.85). CONCLUSIONS: Arteriovenous fistulae created by vascular surgeons, female gender, and the location are risk factors of dysfunction.

Survival of Patients on Hemodialysis with Erectile Dysfunction.

Background and objectives: In patients on hemodialysis, erectile dysfunction is an independent mortality factor. This study aimed to determine the risk factors that affect the survival of hemodialysis patients with erectile dysfunction. Materials and Methods: During a seven-year period, erectile dysfunction was identified among the fatalities reported in patients receiving chronic hemodialysis, on the basis of the International Index of Erectile Function questionnaire. The study covered 70 patients of mean age 57 ± 6.7 years. During the examined period, 42 (60%) patients died at the mean age 57 ± 6.8 years. The study was completed by 28 (40%) patients, aged 57 ± 6.55 years. Laboratory, demographic, anthropometric, and clinical characteristics were recorded using standard methods. Results: Statistically significant differences between the two groups of respondents were found concerning dialysis duration (p < 0.001), number of leukocytes (p = 0.003), adequacy of hemodialysis (p = 0.004), intima media thickness of the carotid artery (p < 0.001), presence of cardiovascular disease (p = 0.03), residual diuresis (p = 0.04), and hemodiafiltration (p < 0.001). Hemodialysis adequacy (B = -9.634; p = 0.017), intima media thickness (B = 0.022; p = 0.003), residual diuresis (B = -0.060; p = 0.007), and lower rates of cardiovascular disease (B = 0.176; p = 0.034) were significant survival predictors among our patients with erectile dysfunction. Conclusions: Risk factors that are associated with improved survival of patients on hemodialysis with erectile dysfunction in our study are: preserved diuresis, high-quality hemodialysis, lower incidence of cardiovascular disease, and less thickening of the intima media of the carotid arteries.

How frequently does palmoplantar psoriasis affect the palms and/or soles? A systematic review and meta-analysis.

INTRODUCTION: Palmoplantar psoriasis (PPP) is a variant of psoriasis that affects the palms and/or soles. Although PPP is a disabling and therapeutically challenging condition, its epidemiology is poorly defined. AIM: To assess the prevalence of PPP locations (palms, soles or both), and to analyse epidemiological and clinical characteristics of the disease. MATERIAL AND METHODS: Two bibliographic databases (MEDLINE and SCOPUS) were used as data sources searched from inception to October 2017. The selection of articles was limited to human subjects and English or French languages. RESULTS: A search resulted in a total of 293 articles, out of which 24 were utilized for the current systematic review and 21 for meta-analysis. All listed studies comprised a total of 2083 patients with PPP, with more males than females. According to the results of meta-analysis, majority of patients had the highest prevalence of both palms and soles involvement (95% CI: 47-67), with an almost equal prevalence showing palmar (21%; 95% CI: 13-30) or plantar (20%; 95% CI: 12-29) involvement. The most prevalent type of PPP was plaque/hyperkeratotic, followed by the pustular type. CONCLUSIONS: Almost three-fifths (59%) of all PPP patients had involvement of both palms and soles, while exclusive palmar or plantar involvement was seen in 21% and 20% of patients, respectively. Future research should be performed to elucidate basic epidemiological and clinical characteristics of PPP, which would be helpful for proper consideration of this condition.
