Abstract In a dynamic market, the city has become a main source of competitiveness, along with financial and economic benefits. Due to the processes of digitalization, a new concept has been developed, namely smart cities. This concept delivers economic and financial potential, not only to cities, but also to urban and local economic development. Therefore, to ensure the establishment of this concept, local government units, i.e., cities, need to have enough financial resources. In addition, the fiscal capacity of their local budgets should be sufficient. The objective of this paper is to evaluate the fiscal capacity of large cities in Croatia over the 2016-2018 period, as well as to present the financial support through funding schemes for the establishment of smart cities. After calculating the level of fiscal capacity of large cities, the analysis revealed interesting results. Only four large cities (Split, Rijeka, Zadar and Pula) achieved positive fiscal capacity in the observed period. This provides evidence of fiscal performance and fiscal capacity for the establishment of smart cities. This concept will enhance the quality of life, stimulate economic growth, sustain local government budgets and create new value for both investors and the local population.
A lack of nurses in the Czech Republic is an issue that has been under discussion for several years. The aim of this paper is to analyze the lack and need of general nurses and midwives in the Hradec Kralove region where the shortage is higher than the national average. The used methods are quantitative research and structured interviews, to determine the number of nurses in healthcare institutions. The study uses data obtained from publicly available sources, i.e., Czech Statistical Office (CSO) and the National Institute of Education (NIE). The shortage of nurses in the Hradec Kralove region can be expected by 2030 to be in the range between 647.6 and 667.1 nurses while maintaining the existing conditions, that is, five times more than at present. In addition to the commonly considered measures that appear in the country’s strategies—such as improving the quality of conditions during studies and during employment, specifying or adjusting the role and competency of nurses and midwives in the healthcare system, or unifying employment standards— a focus on promoting the nursing profession can be recommended. Schools and ministries should be encouraged to focus on and invest in the promotion of this profession, so as to play a key role in recruiting new students for the nursing field of study at a time when the nursing profession is perceived positively, as an embodiment of solidarity and selflessness.
Introduction Results of currently available trials have shown divergent outcomes in diabetic patients undergoing percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Current guidelines do not recommend PCI in patients with diabetes and a SYNTAX score ≥ 23. Aim To compare all-cause 4-year mortality after revascularization for complex coronary artery disease (CAD) in diabetics. Material and methods The study group comprised consecutive patients with three-vessel CAD and/or unprotected left main CAD (≥ 50% diameter stenosis) without major hemodynamic instability, who were treated in two institutions with PCI or referred for CABG. Results Out of 342 diabetics, 177 patients underwent PCI and 165 patients were referred for CABG. The incidence of all-cause death was different between diabetics treated with PCI or CABG at 4 years (16/177, 9.0% vs. 26/165, 15.8%, respectively, p = 0.03). The difference was not evident in non-diabetics (PCI: 41/450, 9.1% vs. CABG: 19/249, 7.6%, p = 0.173). In diabetics, there was a higher incidence of all-cause mortality in PCI patients with intermediate-high (≥ 23) SYNTAX scores compared with those with low (0–22) SYNTAX scores (10/56, 17.9% vs. 6/121, 5.0%, respectively, p < 0.01). On the other hand, diabetics who underwent CABG showed similar mortality rates irrespective of the SYNTAX scores (SYNTAX 0–22: 3/29, 10.3%; SYNTAX ≥ 23: 23/136, 11.9%, p = 0.46). In the subgroup analysis, there was no interaction according to presence or absence of left main CAD (p for interaction = 0.12) as well as according to diabetes status (p for interaction = 0.38), whereas gender and SYNTAX scores were differentiators between PCI and CABG with a p for interaction < 0.1. Conclusions Our analysis supports recent evidence that diabetes is not a differentiator between PCI and CABG.
INTRODUCTION Hepatitis C Virus (HCV) is the leading cause of chronic liver disease and is a serious global health problem. Hepatitis C infection is highly prevalent in patients with end stage renal disease (ESRD), due to frequent exposure to blood and blood products, nosocomial transmission of HCV, and prolong hemodialysis duration. The aim of the study was to evaluate the influence of IL-33/ST2 signaling pathway on severity of the liver disease in ESRD HCV+ patients. METHODOLOGY Blood samples from patients with end stage renal disease (ESRD) and hepatitis C infection (HCV), 20 patients with HCV infection, 20 patients with ESRD and 20 healthy control donor patients were taken for the examination of biochemical parameters, for the determination of the serum cytokine concentration, and for the molecular diagnostics of HCV. RESULTS Systemic sST2 positively correlated with serum level of urea and creatinine, respectively. Serum sST2 was significantly increased in ESRD HCV+ patients in comparison to HCV+ group. sST2/IL-1, sST2/IL-4 and sST2/IL-23 ratios were significantly increased in serum of ESRD HCV+ patients in comparison to HCV+ patients. Significantly higher systemic level of sST2 and sST2/IL-1 and sST2/IL-4 ratios were measured in ESRD patients compared to non-ESRD patients. CONCLUSION These results suggested that elevated level sST2, as the consequence of renal failure, causes less destruction of liver in HCV infection.
The accumulation of organochlorines (OCs) in mussel tissue depends on the physiological and biochemical status of the organism and its interaction with the environment. Mytilus galloprovincialis, 2- and 1-year-old mussels, sampled from Mali Ston Bay, a reference area, and transplanted to Kaštela Bay in cages, were used for the assessment of OC levels and influence of biological parameters on accumulation. Results of bimonthly exposures during one year highlighted that OC accumulation decreases with increasing mussel age. Polychlorinated biphenyls (PCBs) and p,p′-dichlorodiphenyltrichloroethane (p,p′-DDTs) increased, while organochlorine pesticide (OCP; i.e., HCB, lindane, heptachlor, and aldrin) variations were very low. Statistical analysis generally did not confirm the significant effect of lipid content on the accumulation of OCs in mussel tissue. OC levels in mussels were below the maximum permitted levels for human consumption (European Commission).
Presentations of virtual cultural heritage artifacts are often communicated via the medium of interactive digital storytelling. The synergy of a storied narrative embedded within a 3D virtual reconstruction context has high consumer appeal and edutainment value. We investigate if 360° videos presented through virtual reality further contribute to user immersion for the application of preserving intangible cultural heritage. A case study then analyzes whether conventional desktop media is significantly different from virtual reality as a medium for immersion in intangible heritage contexts. The case study describes bridge diving at Stari Most, the old bridge in Mostar Bosnia. This application aims to present and preserve the bridge diving tradition at this site. The project describes the site and history along with cultural connections, and a series of quiz questions are presented after viewing all of the materials. Successful completion of the quiz allows a user to participate in a virtual bridge dive. The subjective evaluation provided evidence to suggest that our method is successful in preserving intangible heritage and communicating ideas in key areas of concern for this heritage that can be used to develop a preservation framework in the future. It was also possible to conclude that experience within the virtual reality framework did not affect effort expectancy for the web application, but the same experience significantly influenced the performance expectancy construct.
The novel coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still progressing and has been recorded in more than 210 countries and territories worldwide. In Bosnia and Herzegovina, the first cases of COVID-19 were detected on March 5, 2020 in the entity of the Republic of Srpska and on March 9, 2020 in the entity of the Federation of Bosnia and Herzegovina. By May 16, 2020, more than 2,200 COVID-19 cases had been recorded in both entities, with a mortality rate of 5.8% (131 of 2,231 cases). The aim of this ongoing study is to present the current epidemiological and sociodemographic parameters of 380 COVID-19 patients diagnosed at the University Clinical Hospital Mostar (UCH Mostar) during the first two months of the COVID-19 pandemic. Of those 380 patients, 60 (15.8%) required hospitalization. The mortality rate was 5% (19/380). The highest mortality rate (15.2%, 12/79) was recorded in the patients aged ≥65 years. In addition to this single-center experience of the ongoing COVID-19 pandemic, we discuss the epidemiological measures imposed in Bosnia and Herzegovina, with an emphasis on the restrictive measures. The COVID-19 pandemic is still ongoing in Bosnia and Herzegovina.
This case trial reports the effects of L-carnosine supplementation on neuromuscular performance, brain metabolism, and various patient- and clinician-reported outcomes in a case series of patients with multiple sclerosis (MS). Two women (aged 37 and 48) and a man (age 48 years) who fulfilled the 2017 McDonald criteria for MS diagnosis, and were free of other major chronic diseases or acute disorders were recruited for this case study. The duration of illness was 4 years in CASE 1 (37-year old women), 5 years in CASE 2 (48-year old men), and 15 years in CASE 3 (48-year old women). L-carnosine (2 g/day) was administered orally during 8 weeks in all MS patients. The trial was registered at ClinicalTrials.gov (ID NCT03995810). The intensity of symptoms and signs of MS after L-carnosine administration diminished in 5 out of 7 domains in CASE 1, in 3 out of 7 domains in CASE 2, and one domain in CASE 3; general fatigue has been reduced in all three cases at the follow-up. The Visual Analog Scale scores for numbness, weakness, pain, and depression decreased in all MS patients at post-administration. This was accompanied by an improved walking distance to exhaustion in all patients, with values improved for 51.1% in CASE 1, 19.5% in CASE 2, and 2.1% in CASE 3 at 8-week follow-up. An increase in serum total antioxidant capacity was found at 8-week follow-up in all patients (from 4.6 to 49.6%); this was accompanied by lower blood lactates at follow-up in all cases (23.5% on average). Single-voxel 1.5 T MRS revealed an increased brain choline-contained compounds (18.9% on average), total creatine (21.2%), and myo-inositol levels (12.3%) in girus cinguli at 8-week follow; this was accompanied by a drop in brain glutamate for 22.6% on average. This case report suggests the favorable effects of medium-term L-carnosine as a possible adjuvant treatment to improve selected patient- and clinician-reported outcomes in a man and two women suffering from MS. There is a need for larger and more rigorous human intervention studies to corroborate these preliminary findings. This study was funded by the Serbian Ministry of Education, Science and Technological Development (#175,037); the Provincial Secretariat for Higher Education and Scientific Research (#114–451-710); the Faculty of Sport and Physical Education, Novi Sad; and CarnoMed LLC, Novi Sad.
Abstract Osteoprotegerin (OPG) regulates bone metabolism by reducing the activation of osteoclasts, but may also be involved in blood vessel calcification and atherosclerosis. Within endothelial cells OPG is stored in Weibel–Palade bodies (WPBs). Blood kinetics of OPG are essentially unknown. We aimed to assess these using two distinct in vivo models; one after stimulation with desmopressin (DDAVP) and another after stimulation with lipopolysaccharide (LPS). Both clinical trials were conducted at the Department of Clinical Pharmacology at the Medical University of Vienna, Austria. Participants received desmopressin (0.3 µg/kg), LPS (2 ng/kg), or placebo (sodium chloride 0.9%) with subsequent blood sampling at time points up to 24 hours after administration. The primary objective of this study was to investigate the plasma kinetics of OPG after stimulation with desmopressin and LPS. Secondary analyses included the release of other WPB contents including von Willebrand factor (vWF). This analysis included 31 healthy volunteers (n = 16 for desmopressin and placebo, n = 15 for LPS). Infusion of desmopressin did not increase OPG concentrations compared with placebo, while LPS infusion significantly increased OPG levels, both compared with desmopressin (p < 0.0001) and to placebo (p = 0.004), with a maximum of ∼twofold increase in OPG levels ∼6 hours after infusion. von Willebrand factor levels increased after both desmopressin and LPS infusion (p < 0.0001), with a maximum of ∼threefold increase 2 hours after desmopressin and a maximum of ∼twofold increase 6 hours after LPS administration. In conclusion, we report that, in contrast to vWF, OPG is not released upon stimulation with desmopressin, but increases significantly during experimental endotoxemia.
Computerization of education process is a contemporary trend that is emerging at the global scale, but with substantial regional disparities in the level of its implementation. The present study is aimed at revealing the current situation regarding computer technology use in geographical education in primary and secondary education in Bosnia and Herzegovina through a survey conducted among geography teachers from two typical regions – Canton of Sarajevo with predominantly urban features and Central Bosnia region, where majority of population lives in rural areas. The obtained results suggest that general situation with regard to the level of computer skills identified among geography teachers is satisfying, but that there are still certain disparities across different categories of respondents. It turns out that younger teachers, as well as those from urban region possess a higher level of IT skills and use this technology more frequently for the preparation and implementation of teaching process. At the same time, significant differences regarding the respondents gender have not been found, except in the context of extracurricular activities.
Seismology provides important constraints on the structure and dynamics of the deep mantle. Computational and methodological advances in the past two decades improved tomographic imaging of the mantle and revealed the fine-scale structure of plumes ascending from the core-mantle boundary region and slabs of oceanic lithosphere sinking into the lower mantle. We discuss the modeling aspects of global tomography including theoretical approximations, data selection, and model fidelity and resolution. Using spectral, principal component, and cluster analyses, we highlight the robust patterns of seismic heterogeneity, which inform us of flow in the mantle, the history of plate motions, and potential compositionally distinct reservoirs. In closing, we emphasize that data mining of vast collections of seismic waveforms and new data from distributed acoustic sensing, autonomous hydrophones, ocean-bottom seismometers, and correlation-based techniques will boost the development of the next generation of global models of density, seismic velocity, and attenuation. ▪ Seismic tomography reveals the 100-km to 1,000-km scale variation of seismic velocity heterogeneity in the mantle. ▪ Tomographic images are the most important geophysical constraints on mantle circulation and evolution.
Abstract Xanthene derivatives have become a group of molecules of great importance in discovering of new anticancer drugs. Recent studies of our group performed on xanthen-3-one and xanthen-1,8-dione derivatives have shown their antiproliferative activity on HeLa cervical cell lines. Obtained IC50 values together with calculated molecular descriptors were subjected to Quantitative Structure–Activity Relationship (QSAR) study in order to identify the most relevant molecular features responsible for the observed antiproliferative activity of compounds. Partial least square statistical method and the same training and test set were used to obtain statistical parameters for internal and external validation in 2D- and 3D-QSAR study. The obtained QSAR models have shown next results: 2D-QSAR: R 2 = 0.741, Q 2 = 0.792, R 2 pred = 0.875 and 3D-QSAR: R 2 = 0.951, Q 2 = 0.830, R 2 pred = 0.769. Based on the performed QSAR analysis and calculated ADMET properties, novel xanthene derivatives with enhanced antiproliferative activity were designed. Communicated by Ramaswamy H. Sarma
