Introduction: To show the importance of optical coherence tomography (OCT) angiography imaging of superficial and deep capillary network in patients with non-proliferative diabetic retinopathy (NPDR), and to show the correlation between blood glucose level and changes in the foveal microvasculature. Methods: A cross-sectional study was performed on eyes with NPDR and healthy subjects using a highspeed 840-nm-wavelength spectral-domain optical coherence tomography instrument (RTVue XR Avanti; Optovue, Inc, Fremont, California, USA). Blood flow was detected using the split-spectrum amplitude-decorrelation angiography algorithm. A fully automated microstructural analysis of the foveal avascular zone (FAZ) and avascular surfaces was performed. Quantitative values from diabetic patients were compared with those of healthy subjects. Data about blood status in diabetic patients and healthy subjects were taken from patients’ medical history. Results: Size of both, FAZ and vascular dropout are significantly different between healthy patients and patients with NPDR. OCT angiography detected enlargement and distortion of the foveal avascular zone, retinal capillary dropout, and a higher number of vascular loops and microaneurysms. Sizes of FAZ and vascular dropout increase with the duration of disease. Central macular thickness (CMT) is not significantly different between healthy patients and patients with NPDR. A study has proven a positive correlation between the size of FAZ and the size of vascular dropout in superficial vascular plexus in patients that have DM over 10 years. Conclusion: A qualitative and quantitative OCT angiography approach to retinal vascular status can offer objective data on monitoring patients with non-proliferative diabetic retinopathy as well as indicate the progression of the disease.

Introduction: Infection with human papillomavirus is the main cause of cervical carcinoma. In Bosnia and Herzegovina (BIH) 556 cases of cervical carcinoma are diagnosed annually, and 141 women die from it. Aim: To determine the most common HPV type found in ASCUS and LSIL and progression, regression and persistence of lesions. Methods: In a retrospective study, 11 051 PAP tests, performed in several private gynecological practices located in Tuzla Canton from January 2016 to December 2019, were analyzed. In processing of data , X2 – statistical method was used. Results: 11051 PAP test were inspected. Normal findings were found in 90.48% (N-10002) and pathological findings in 9.49% (N- 049). ASCUS was present in 4.9% (N-544), LSIL in 3.04% (N-337), HSIL in 0.74% (N-84), ASC-H in 0.27% (N-30) and AGC in 0.49% (N-55) of cases. The most common is HPV 16, found in 50.5% (N-44) of ASCUS and LSIL. Monoinfection with HPV 16 was found in 40.9% (N-18) ASCUS (N-3) and LSIL (N-15), and a combination of HPV 16 with other types like HPV 18, 31, 33, 39 in 59% (N-26). Progression of ASCUS lesion in HSIL 1.6% (N-2), and LSIL 9.6% (N-12). Progression of LSIL to HSIL was found in 9.0% (N-10). HSIL progresses significantly more frequent from LSIL (p<0.05) than from ASCUS changes. Lesions that progress into higher grade HSIL are HPV 16 positive. Progression into HSIL is not found in patients with low-risk HPV 6 and 11 infection. Conclusion: Women infected with HPV 16 have more a frequent progression of a lesion into higher grade HSIL. They should be intensively monitored because of the increased risk for development of cervical carcinoma.

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.

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.

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.

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.

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.

<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>

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.
