Women represent an increasing proportion of the overall rheumatology workforce, but are underrepresented in academic rheumatology, especially in leadership roles [1].The EULAR Task Force on Gender Equity in Academic Rheumatology has been convened to establish the extent of the unmet need for support of female rheumatologists, health professionals and non-clinical scientists in academic rheumatology and develop a framework to address this through EULAR and EMEUNET.To investigate gender equity in academic rheumatology, an anonymous web-based survey was targeted at the membership of EULAR and Emerging EULAR Network (EMEUNET) and their wider networks. The survey was developed based on a narrative literature review [1], best practice from The Association of Women in Rheumatology, a survey of task force members and face-to-face task force discussions. Personal experiences were explored and 24 potential interventions to aid career advancement were ranked. Statistics were descriptive with significance testing for male/female responses compared using chi-squared/t-tests. The level of significance was set at p<0.001.A total of 301 respondents from 24 countries fully completed the survey. By profession, 290 (86.4%) were rheumatologists, 19 (6.3%) health professionals, and 22 (7.3%) non-clinical scientists. By gender, 217 (72.1%) were women, 83 (27.6%) men, and 1 (0.3%) third gender. By age, 203 (67.5%) were 40 or under. By ethnicity, 30 (10.0%) identified themselves as ethnic minority. A high proportion of respondents reported having experienced gender discrimination (47.2% total: 58.1% for women and 18.1% for men) and sexual harassment (26.2%: 31.8% and 10.8% respectively) (Figure 1). Chi-squared tests on the numbers on which these proportions were based showed statistically significant differences between women and men in having experienced gender discrimination (Χ2=36.959 (df=1), p <0.001) and sexual harassment (Χ2=12.633 (df=1), p <0.001). The highest-ranked interventions for career advancement regardless of respondents’ gender included: leadership skills training; speaking/presentation/communication skills training; information on training/career pathways; effective career planning training; support on grant writing applications; and high-impact scientific writing master-classes (Figure 2). Only 8 of 24 proposed interventions showed a significantly higher ranking (p<0.001) by female respondents and these typically related to promotion of female role models and gender-balance in committees, editorial boards and research funding (Figure 2).Figure 1.Perceived gender discrimination and sexual harassment, 301 responsesFigure 2.Mean perceived utility of potential interventions for career advancement by gender and statistically significant gender differences (p<.001), 300 responsesThe results of the survey will inform the development of task force policy proposals for interventions to support career advancement among EULAR and EMEUNET members. The identified interventions have potential to support career advancement of all rheumatologists, health professionals and non-clinical scientists regardless of gender.[1]Andreoli L, Ovseiko PV, Hassan N, Kiltz U, van Mens L, Gossec L, et al.

Introduction: Optical coherence tomography angiography (OCT-A) is a useful diagnostic tool for assessing eyes’ health in patients with chronic diseases, such as diabetes, hypertension, Parkinson’s disease and chronic kidney disease (CKD). Aim: To detect changes in macular structure and retinal vascular meshwork in the macular area and peripapillary in patients with chronic kidney disease (CKD). Methods: This cross-sectional study included 80 eyes of patients with CKD in stages 2, 3 or 4, who were followed-up in the Nephrology Clinic of University Clinical Center Sarajevo. All patients were categorized according to the stage of CKD. All patients were scanned by a high-speed 840-nm-wavelength spectral-domain optical coherence tomography instrument (RTVue XR Avanti; Optovue, Inc, Fremont, California, USA). Blood flow was detected using a split-spectrum amplitude-decorrelation angiography algorithm. A fully automated microstructural analysis of the foveal avascular zone (FAZ), FAZ perimeter, foveal vessel density in a 300-μm area around the FAZ (FD), nonflow area, flow index in superficial and deep vascular plexus, choriocapillary flow, vascular density, radial peripapillary capillary density was performed. Results: When comparing patients with CKD stage 2 and stage 3 there were no statistically significant changes in microvascular parameters on OCT angiography, as well as when comparing patients with CKD stage 3 and stage 4. But in the comparison between patients with less developed CKD (stage 2) and terminal CKD (stage 4) there was a significant difference between some microvascular parameters such as FAZ area, FAZ perimeter, choriocapillary flow. Conclusion: Many studies demonstrated that evaluation of the microvascular changes in different retinal layers using SS-OCTA may be considered as a key to assessing the systemic perfusion status. Evaluation of retinal microvasculature may ease the management and approach of patients with CKD, having in mind that the retinal and the kidney vascular network are, concerning structure, development and the function, very similar.

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).

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.

We are living in times where a viral disease has brought normal life in much of the world to a halt. The novel coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19) started in December 2019 in Wuhan, China initially and in a short time crossed the European borders. After mitigating the epidemic in China, Italy became one of the most COVID-19 affected countries worldwide. International travelers are important sources of infectious diseases and a possible source of epidemic. Due to its political, geographic, and cultural similarities, Italy is one of the main economic partners of Southeast European (SEE) countries. Our data show that infection in index cases in all 11 SEE countries was travel-related with Italy being a source country for 8/11 countries. After the first case identifications on February 25, the number of cases in SEE countries is continually rising reaching the total number of 15,612 with 565 fatal cases and overall case fatality ratio (CFR) of 3.6 (median 3.8, range 0.8-5.5) by April 10, 2020. At a time when the COVID-19 pandemic is approaching its peak, apart from the problems with treatment of the disease and care for critically ill patients, there are other equally important problems, such as organization of outbreak response, provision of health care, lack of hospital personnel, disruption of personal protective equipment supply chains and health care workers (HCWs) protection. But what is more important is the heroic behavior of the HCWs who are showing their humanity by disregarding their lives.

Američki cvrčak (Scaphoideus titanus Ball.) jedini je poznati prirodni vektor zlatne žutice vinove loze. Hrani se sišući sokove iz floema vinove loze, pri čemu usvaja fitoplazmu (Flavescence dorée) koju unosi u svoj organizam i na taj način ju prenosi hranjenjem sa zaraženih na zdrave trsove. Za uspješno suzbijanje američkog cvrčka vrlo je bitno poznavati njegovu biologiju i ekologiju. Temeljem toga cilj ovog rada bio je istražiti prisutnost i utvrditi brojnost američkog cvrčka, te učinkovitost tretiranja. Istraživanje je postavljeno 2018. godine na lokalitetu Ilok. Pratila se dinamika pojave i utvrdila se brojnost ličinki i odraslih oblika američkog cvrčka u vinogradima na tri različite lokacije u Iloku. Dinamika pojave i brojnost pratila se uz pomoć žutih ljepljivih ploča. Istraživanje je pokazalo da je prosječan ulov po žutoj ploči bio 2, 5 ili 9 američkih cvrčaka, ovisno o lokalitetu. Učinkovitost tretiranja pokazala se najuspješnijom u vinogradu na lokaciji „Principovac“, u kojemu su korištena zaštitna sredstva različitih skupina prema mehanizmu djelovanja. U istraživanju nisu utvrđeni simptomi zlatne žutice vinove loze.

Within the micro and nano world, tiny membrane-enclosed bits of material are more or less free to move and act as communication tools within cells, between cells, between different tissues and between organisms in global environment. Based on the mechanism of membrane budding and vesiculation that includes all types of cells, in this review, we attempted to present a review on SARS-CoV-2 virus actions in compartments of different scales (cells and their surroundings, tissues, organisms and society). Interactions of the virus with cells on a molecular level, with neural system, endothelium, hematopoietic system, gastrointestinal system and genitourinary system. Transmission route between organisms and between mother and fetus are considered. Also, transmission of virus through contact with materials and with environment, the suggested measures to prevent contamination with the virus and to support the organism against the disease are given.

<p>The aim of the paper was to conduct Critical Discourse Analysis of political discourse of three<br />High Representatives stationed in Bosnia and Herzegovina for the period 2006 &ndash; 2010. In order to<br />carry out the envisaged analysis, the key tool for language description was Systemic Functional<br />Grammar. The theory elaborates significance of language in everyday life and its role in the<br />construction of meanings. The analytical framework for CDA consisted of three stages: description,<br />interpretation and explanation. The paper shows that CDA approach to language analysis and SFG<br />descriptive language tools provide a valuable platform for investigations of language in context. The<br />findings highlight different communicative models which emerge as a result of lexico-grammatical<br />choices that political actors make in specific contexts and under specific circumstances.</p>

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.

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.

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.
