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

On Oscillations and Noise in Multicomponent Adsorption: The Nature of Multiple Stationary States

Starting from the fact that monocomponent adsorption, whether modeled by Lagergren or nonlinear Riccati equation, does not sustain oscillations, we speculate about the nature of multiple steady state states in multicomponent adsorption with second-order kinetics and about the possibility that multicomponent adsorption might exhibit oscillating behavior, in order to provide a tool for better discerning possible oscillations from inevitable fluctuations in experimental results or a tool for a better control of adsorption process far from equilibrium. We perform an analysis of stability of binary adsorption with second-order kinetics in multiple ways. We address perturbations around the steady state analytically, first in a classical way, then by introducing Langevin forces and analyzing the reaction flux and cross-correlations, then by applying the stochastic chemical master equation approach, and finally, numerically, by using stochastic simulation algorithms. Our results show that stationary states in this model are stable nodes. Hence, experimental results with purported oscillations in response should be addressed from the point of view of fluctuations and noise analysis

MENTALIZATION AND PSYCHOPHARMACOTHERAPY IN PATIENTS WITH PERSONALITY AND EATING DISORDERS

Contemporary psychiatry pays more and more attention to the patient’s capacity regarding acceptance of psychiatric drugs. Understanding the basis of our treatment’s effectiveness becomes more challenging. To understand psychiatric treatment psychiatrists must pay full attention to mentalizing and the conditions under which this basic human capacity becomes impaired especially in those suffering from personality and eating disorders. This paper discusses the meaning and clinical applications of the mentalizing related to psychopharmacotherapy for personality and eating disorders patients, including suicidality

Farmland real estate investment trusts

The modern era has brought the need for the establishment of farmland real estate investment trusts. The establishment of these trusts positively affects growth and development of agricultural sector and ultimately contributes to global poverty reduction and sustainable development of the world economy and society. The research objective is to highlight the importance of these institutional investors as a new mechanism for investing in farmland and an additional source of financing for the agricultural sector. No studies on this issue in domestic and insufficient number of them in foreign literature have been a motive for the conducted research. The intention is to introduce investment community with the basic characteristics of farmland real estate investment trusts, as well as the key factors that arouse interest and lead to investment in farmland as new asset class

Limitations and opportunities for funding agriculture and rural development in the Republic of Serbia

Funding is one of the most important issues of agriculture and rural development of the Republic of Serbia, because insufficient financial resources allocated to this sector of the country's economy are considered the key limitation for better valorization of agricultural resources and the revitalization of rural areas. Agribusiness and rural development have a major socio-economic importance for the Republic of Serbia, which is supported by a number of strategic documents, development indicators and scientific and expert analysis implemented in the country and at a global level; therefore, the aim of this study is to determine whether it is necessary and possible to improve the funding of agricultural development and rural economy of the Republic of Serbia, in current conditions. The survey results indicate potential sources, i.e., the possible ways of funding agriculture and non-agricultural activities in the rural areas of the Republic of Serbia.Publishe

EuReCa Serbia Subotica 2015-2016: Does the system strengthening lead to better results?

Aims and goals: Comparing the data’s of EuReCa-Serbia project conducted during 2015 and 2016 and it’s mutual analysis in Subotica research center. Methodology: Prospective study of an observational trail of the European Resuscitation Council registered Clinical Trial NCT02236819 and approved by the US healthcare authorities. The analyzed data’s are collected in the EMS Subotica center during 2015 and 2016 and has been uploaded by lead investigator of a participating center into an online database and application at www. eureca.rs. Results: During 2015 cardiac arrest has been confirmed by the physician of the EMS in 63.6 cases per 100.000 citizens, while in 2016 the number of cases was 82,6/100.000 citizens. Cardiopulmonary resuscitation was attempted in 58,7/100.000 citizens in 2015., and in 77,7 /100.000 citizens during 2016. The most common aetiology of cardiac arrest has cardiac cause for both years; 21,6/100.000 in 2015, and 27,5/100.000 in 2016. The place of cardiac arrest for both years in most cases is place of residence; 40,2/100.000 in 2015 and 58/100.000 during 2016. In 3,5/100.000 cases CPR was dispatcher assisted during 2015. and for 2016 in 8,5/100.000 cases. OHCA is witnessed in 38.8 /100.000 during 2015. and in55/100.000 cases for 2016. During 2015 in 5,6/100.000 cases the bystanders initiated CPR. For 2016, this happened in 14/100.000 cases. The initial rhythm was shockable in 15,5/100.000 cases for the year of 2015 and in 17/100.000 during 2016. Before the EMS arrival AED has not been used during 2015, but in 2016 AED was in use twice. ROSC was achieved in 7,8 patients per 100.000 citizens in 2015. In 2016 the incidence of ROSC was 23,3/100.000 Conclusion: Thanks to the two-year follow-up of the data’s in the observed period, we can conclude that the number of patients with shockable rhythm and achieved ROSC has significantly increased. Strengthening the system via continuous education of each link of the Chain of Survival will lead to better results and improvement the work quality

EuReCa Serbia One 2014 - Research center Subotica: Witnessed out-of-hospital cardiac arrest analysis

INTRODUCTION: Cardiac arrest is one of the main death causes all over the world. Many studies have led to the identification of the main predictors that can positively affect the survival rate of these patients, who were eventually incorporated into a single chain of survival. By involving the Republic of Serbia in an international, multicenter project EuReCa One 2014, of European Resuscitation Council (ERC) organized by Resuscitation Council of Serbia and Section of emergency medicine, the first time we get relevant information in this area and for our country which allows us to further work on improving measures implemented in the treatment of these patients. AIM: analysis of providing of basic life support measures (BLS) by bystander to the patients with out of hospital cardiac arrest (OHCA) according to prospective research EuReCa One 2014 for Subotica, in relation to the total number of affirmed OHCA. MATERIALS AND METHODS: A prospective collection of data via unique questionnaire for OHCA in the municipality of Subotica in the period from 01.10.2014. to 31.03.2015. Data are presented in absolute values as well as the incidence per 100,000 inhabitants. RESULTS: In the period from 01.10.2014 to 31.03.2015. in the municipality of Subotica there were 47 (33.2 / 100,000 inhabitants) OHCA's. In 44 (31.09 / 100.000, 93.62%) of these patients Emergency medicine service (EMS) reacted by providing measures of cardiopulmonary resuscitation. Of these 47 patients with OHCA as 35 (24.73 / 100000) were witnessed, of which 24 (16.95 / 100.000) by bystander, and 11 (7.77 / 100.000) by members of the EMS. The results show that the highest percentage of initial rhythm as ventricular fibrillation (VF), as well as the largest number of return of spontaneous circulation (ROSC) were in the group of patients whose OHCA was witnessed by the EMS (VF, 63.5%, ROSC 54.5%) even though the group was the oldest (average 69 years), while the lowest percentage of VF and ROSC was in a group of unwitnessed OHCA's which was the youngest group of patients with an average age of 58 years. Telephone assisted CPR was conducted in only 4 cases, while the measures of basic life support (BLS) were provided by the bystander in only 5 cases (20.5% of witnessed OHCA's) CONCLUSION: This study showed that systematic work on increasing the number of provided BLS measures by bystander to the patients with OHCA must be conducted, because it can positively affect survival rate of these patients

Health center Temerin: Our participation in EURECA One 2014 - Serbia program

Introduction: Sudden cardiac arrest is a natural and unexpected loss of heart function and breathing, which happens within one hour after first symptoms at presumably healthy person or with previously stable condition. In average, 10% of all patients resuscitated by the EMS survives. However, when CPR is initiated by witnesses and AED is used, survival rate increases to 38%. Number of OHCAs, as well as the number of conducted resuscitations are documented through regular monitoring of quality indicators in emergency medical service. Aim: Tracking the incidence, treatment and outcome of cardiac arrest from October 1 to October 31 2014, in Temerin municipality, with the purpose of acquiring precise information about this disease and improving quality of cardiac arrest management. Method: Health Center of Temerin joined the prospective observational trail of the European Resuscitation Council. During the month October 2014, data were collected by the physicians working in this medical facility. Results: EMS of Temerin provides urgent medical assistance for 28296 people, according to population census from the year 2011. Average age of the population is 38,3 years. Out of hospital Cardiac arrest was documented 3 times, and that's 1,15% of all the EMS interventions during the observed period (3/260), the incidence being 11/100 000. Conclusion: We find that further investigation of out of hospital cardiac arrest is necessary, and since all the participants in this study expressed genuine will to continue, more detailed conclusions will be available soon
