Predictive parameters functioning arteriovenous fistula for hemodialysis in the elderly
© 2019, University of Kragujevac, Faculty of Science. All rights reserved. Elderly patients with end stage kidney disease represent a challenge for surgeons to create a vascular access. Determine predictive parameters functionality of the arteriovenous fistulas for hemodialysis in the elderly. The study was organized as a retrospective study at the Center for Dialysis, Clinic for Urology and Nephrology, Clinical Center Kragujevac. The study included patients older than 65 years with arteriovenous fistula thrombosis, in the period of four years, in which there is information on the length of the functioning fistula. The study included 48 patients, mean age 71.3±5.2 years, 29 (60%) men and 19 (40%) women. The data were analyzed according to gender and demographic structure, type of anastomosis, positioning, length of functioning fistulas, and the lumen diameter of the arteries and veins that are used to create a fistula. The median length of functioning arteriovenous fistula, based on Kaplan-Meier model, is 16 months (95% CI 6.9- 25.1). Median functioning for proximaly located fistulas was 24 months (range, 1-259), while median functioning in patient with distally located fistulas was 8 months (range, 1-96). The difference in relation to the positioning of the fistula was statistically significant (p=0.006). In univariate Cox regression model, a statistically significant predictor of the functioning of arteriovenous fistulae is fistula positioning (B=0.700; p=0.022). The predictive parameter of survival of arteriovenous fistulas in elderly is proximally located fistula
Uticaj letnjeg i zimskog perioda ishrane na telesnu razvijenost krava simentalske rase
The paper analyzed linear type traits and influence of summer and winter nutrition on body development of Simmental cattle. Test cows (paternal a half-sisters) were located in identical breedingconditions on the eastern slopes of Mount Kopaonik.Considering that expression of the genetic potential depends on the environment in which the organisms exist, the differences between summer and winter period feeding of Simmental cattle were not statistically significant (Tukey's test, p> 0.05) for the investigated properties of linear type traits and body development.U radu su analizirane linearne ocene tipa i uticaj letnjeg i zimskog perioda ishrane na telesnu razvijenost krava simentalske rase. Ispitivane krave (polusestre po ocu) nalazile su se u identičnim uslovima gajenja na istočnim padinama planine Kopaonik. S obzirom da ispoljavanje genetskog potencijala zavisi i od uslova sredine u kojoj egzistiraju organizmi, razlike između letnjeg i zimskog perioda ishrane krava simentalske rase su statistički nesignifikantne (Tukey test,p> 0.05) za ispitivana svojstva linearne ocene tipa i telesne razvijenosti

Rethinking media responsibility in the refugee ‘crisis’: a visual typology of European news
In this paper, we analyse how news images of the 2015 Syrian refugee ‘crisis’ visualise refugees and how, in so doing, they mobilise various forms of moral responsibility in ‘our’ mediated public life – various practical dispositions of action towards the misfortunes of migrants and refugees at Europe’s border. On the basis of empirical material from European news (June-December 2015), we construct a typology of visibilities of the ‘crisis’, each of which situates refugees within a different regime of visibility and claim to action: i) visibility as biological life, associated with monitorial action; ii) visibility as empathy associated with charitable action; iii) visibility as threat, associated with state security; iv) visibility as hospitality, associated with political activism; and v) visibility as selfreflexivity, associated with a post-humanitarian engagement with people like ‘us’. In conclusion, we argue that, important as these five categories of visibility are in introducing public dispositions to action towards the vulnerable, they nonetheless ultimately fail to humanise migrants and refugees. This failure to portray them as human beings with lives that are worth sharing should compel us, we urge, to radically re-think how we understand the media’s responsibility towards vulnerable others

Metabolically Favorable Remodeling of Human Adipose Tissue by Human Adenovirus Type 36
OBJECTIVE—Experimental infection of rats with human adenovirus type 36 (Ad-36) promotes adipogenesis and improves insulin sensitivity in a manner reminiscent of the pharmacologic effect of thiozolinediones. To exploit the potential of the viral proteins as a therapeutic target for treating insulin resistance, this study investigated the ability of Ad-36 to induce metabolically favorable changes in human adipose tissue
Medication calculation skills of graduating nursing students within European context.
To access publisher's full text version of this article, please click on the hyperlink in Additional Links field or click on the hyperlink at the top of the page marked DownloadAim: The aim of this study is to evaluate the medication calculation skills of graduating nursing students in six European countries and analyse the associated factors.
Background: Medication calculation skills are fundamental to medication safety, which is a substantial part of patient safety. Previous studies have raised concerns about the medication calculation skills of nurses and nursing students.
Design: As part of a broader research project, this study applies a multinational cross-sectional survey design with three populations: graduating nursing students, nurse managers and patients.
Methods: The students performed two calculations (tablet and fluid) testing medication calculation skills requiring different levels of conceptual understanding and arithmetic. The managers and patients answered one question about the students' medication kills. In total, 1,796 students, 538 managers and 1,327 patients participated the study. The data were analysed statistically. The STROBE guideline for cross-sectional studies was applied.
Results: Almost all (99%) of the students performed the tablet calculation correctly, and the majority (71%) answered the fluid calculation correctly. Older age, a previous degree in health care and satisfaction with their current degree programme was positively associated with correct fluid calculations. The patients evaluated the students' medication skills higher than the nurse managers did and the evaluations were not systematically aligned with the calculation skills tested.
Conclusions: Nursing students have the skills to perform simple medication calculations, but a significant number of students have difficulties with calculations involving multiple operations and a higher level of conceptual understanding. Due to the variation in students' medication calculation skills and the unalignment between the managers' and patients' evaluations and the calculation tests, further research is needed.
Relevance to clinical practice: Graduating nursing students enter clinical field as qualified professionals, but there is still room for improvement in their medication calculation skills. This calls for attention in the fields of clinical nursing, education and research.

Automatic identification of variables in epidemiological datasets using logic regression
textabstractBackground: For an individual participant data (IPD) meta-analysis, multiple datasets must be transformed in a consistent format, e.g. using uniform variable names. When large numbers of datasets have to be processed, this can be a time-consuming and error-prone task. Automated or semi-automated identification of variables can help to reduce the workload and improve the data quality. For semi-automation high sensitivity in the recognition of matching variables is particularly important, because it allows creating software which for a target variable presents a choice of source variables, from which a user can choose the matching one, with only low risk of having missed a correct source variable. Methods: For each variable in a set of target variables, a number of simple rules were manually created. With logic regression, an optimal Boolean combination of these rules was searched for every target variable, using a random subset of a large database of epidemiological and clinical cohort data (construction subset). In a second subset of this database (validation subset), this optimal combination rules were validated. Results: In the construction sample, 41 target variables were allocated on average with a positive predictive value (PPV) of 34%, and a negative predictive value (NPV) of 95%. In the validation sample, PPV was 33%, whereas NPV remained at 94%. In the construction sample, PPV was 50% or less in 63% of all variables, in the validation sample in 71% of all variables. Conclusions: We demonstrated that the application of logic regression in a complex data management task in large epidemiological IPD meta-analyses is feasible. However, the performance of the algorithm is poor, which may require backup strategies

Background: Hyaluronic filler is a sterile, biodegradable, viscoelastic, isotonic, transparent injectable gel implant which was approved by Food and Drug Administration (FDA) 1996. It is used for face reconstruction and modelling. Case presentation: We report the case of a 40-year-old Serbian woman who presented after surgery of cleft lip, primary and secondary palate. We performed a biphasic therapy; in the first stage in the zone semimucosis lips is initially carried incision scar tissue. The second stage is placed hyaluronan implant. Conclusion: This case illustrates that, although hyaluronic fillers used mainly for correction of healthy tissue can be successfully used in the treatment of postoperative scars
Structure of the attitudes towards cosmetic procedures’ acceptance
© 2019, Serbia Medical Society. All rights reserved. Introduction/Objectives The objective of our study was to investigate the structure of the cosmetic procedures’ acceptance attitudes and differences in acceptance between persons who had undergone minimally invasive cosmetic procedures and those who had not. Methods The study included 245 subjects (treatment group), 21–73 years old (42.02 ± 12.12). The control group included 250 subjects who had not previously undergone cosmetic procedures, also 21–73 years old (40.19 ± 11.71). The control group was balanced with the treatment group according to category distribution of demographic variables. The Acceptance of Cosmetic Surgery Scale, adjusted for cosmetic procedures in general, was used for the evaluation of participants’ attitudes towards these procedures. Results Internal consistency of the scale was α = 0.963, the split-half coefficient of validity was 0.861/0.810, and test–retest correlation coefficient was 0.892. The treatment group has shown overall higher acceptance (t(478) = 27.024, p < 0.001, η2 = 0.6), and higher scores in all three dimensions. No demographic variable has shown significant differences in total or individual factor scores in either group. Conclusion Subjects from both groups had scored higher on items dealing with the advantages of cosmetic procedures on a personal level (Intrapersonal Factor)
