Purpose – The purpose of this paper is to examine the effects that COVID-19 outbreak has had on tourism in Bosnia and Herzegovina (BiH) and specifically in Sarajevo Canton. Methodology – A survey was conducted in two rounds in March and September 2020, and responses were obtained from 126 running businesses from the tourism in Sarajevo Canton about the actual and expected consequences that COVID-19 outbreak has had on their business. The respondents were asked questions about the effects that COVID-19 has had on their business operations during the first six months of COVID-19 outbreak and their expectations for the future. The questions also included issues related to the government interventions and stimulus packages to overcome the effects of COVID-19 to ensure the sustainability of the tourism in Sarajevo Canton. Findings – Our results show that all businesses have faced a significant downturn in their business operations and had to undertake different measures and activities internally to overcome (and survive) the negative effects of the COVID-19 pandemic. The results also show that there is very low level of satisfaction with the government interventions to tourism. Contribution – The findings illustrate and confirm many flaws in tourism system in Sarajevo Canton and BiH where tourism has been developing organically and without proper integration of the private and public industry. Our findings can be used for planning purposes and improvement of the situation during COVID-19 and post-COVID-19 period.

Abstract Large corporate scandals in the US and Europe, from the early 21st century, such as Enron, Parmalat, WorldCom and many others, have seriously shaken public confidence in the auditors’ work. Consequently, many countries have recognized the need for introduce the forensic accounting as a more advanced and reliable form of protection against manipulative financial reporting by companies, and have completed the accounting profession with the forensic accountant title, as an active fighter against various types of frauds in companies.

Genetic variants in FOXO3 are associated with longevity. Here, we assessed whether blood DNA methylation at FOXO3 was associated with cancer risk, survival, and mortality. We used data from eight prospective case–control studies of breast (n = 409 cases), colorectal (n = 835), gastric (n = 170), kidney (n = 143), lung (n = 332), prostate (n = 869), and urothelial (n = 428) cancer and B-cell lymphoma (n = 438). Case–control pairs were matched on age, sex, country of birth, and smoking (lung cancer study). Conditional logistic regression was used to assess associations between cancer risk and methylation at 45 CpGs of FOXO3 included on the HumanMethylation450 assay. Mixed-effects Cox models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for associations with cancer survival (total n = 2286 deaths). Additionally, using data from 1088 older participants, we assessed associations of FOXO3 methylation with overall and cause-specific mortality (n = 354 deaths). Methylation at a CpG in the first exon region of FOXO3 (6:108882981) was associated with gastric cancer survival (HR = 2.39, 95% CI: 1.60–3.56, p = 1.9 × 10−5). Methylation at three CpGs in TSS1500 and gene body was associated with lung cancer survival (p < 6.1 × 10−5). We found no evidence of associations of FOXO3 methylation with cancer risk and mortality. Our findings may contribute to understanding the implication of FOXO3 in longevity.

An increasing number of studies have revealed that dysregulated lipid homeostasis is associated with the pathological processes that lead to Alzheimer’s disease (AD). If changes in key lipid species could be detected in the periphery, it would advance our understanding of the disease and facilitate biomarker discovery. Global lipidomic profiling of sera/blood however has proved challenging with limited disease or tissue specificity. Small extracellular vesicles (EV) in the central nervous system, can pass the blood‐brain barrier and enter the periphery, carrying a subset of lipids that could reflect lipid homeostasis in brain. This makes EVs uniquely suited for peripheral biomarker exploration.

Background: Non-alcoholic fatty liver disease (NAFLD) is an increasingly common cause of chronic liver disease and is becoming a major public health problem. NAFLD has been recognized as a hepatic manifestation of metabolic syndrome, associated with systemic diseases such as cardiovascular disease (CVD) and chronic kidney disease (CKD). Objective: The aim of this study was to examine the role of serum LFT parameters and renal function parameters as predictors of unmanifested liver disease. Methods: In this study, the presence of possible liver disease detected by biochemical parameters and confirmed by Transient Liver Elastography (TE) in a group of patients with different stages of chronic kidney disease (CKD) was investigated. Patients with various stages of CKD were divided into five subgroups regarding aetiology: nephroangiosclerosis, diabetic nephropathy, glomerulonephritis and pyelonephritis, autoimmune kidney disease, and polycystic and another morphological kidney disease. Liver stiffness was used to quantify liver fibrosis while Controlled attenuation parameter (CAP) was used to quantify liver steatosis. Functional liver tests and biochemical parameters of kidney function were measured in all patients. Results: Statistical analysis used in this study was a decision tree as a predictive model to map observed variables resulting in the conclusion about outcomes. The application of existing laboratory parameters, in combination with other parameters in presence of the defined etiological factors of kidneys diseases, indicate development of hepatic diseases. Higher values of phosphorus and low values of ferritin in patients with autoimmune kidney disease, and polycystic and another morphological kidney disease, expresses steatosis of the hepatic parenchyma. Conclusion: In contrary, low values of phosphorus and higher values of ferritin in patients with nephroangiosclerosis, diabetic nephropathy, glomerulonephritis and pyelonephritis, are in a favour steatosis of the hepatic parenchyma. Serum values of phosphorus and ferritin are valuable predictors of the liver disease in patients with end-stage kidney diseases of different aetiology.

INTRODUCTION Pregnancy is a unique experience accompanied by significant physiological, biochemical, and psychological changes that may affect a woman's mental health status. With the development of a holistic approach, midwives have become continuous support during pregnancy and childbirth. Childbirth education is an intervention that affects delivery outcomes and the experience of childbirth. Music therapy has been proven to be a safe and effective non - pharmacological method to gain in pregnancy and puerperium. The study aimed to prove the impact of educating pregnant women and listening to classical music on the experience of childbirth pains and the occurrence of psychological symptoms during puerperium. METHODS A prospective randomized controlled trial (n=198) was conducted. The experimental group of pregnant women was educated during pregnancy and listened to classical music the rest of the pregnancy, while the control group received the usual care. The VAS scale was used to assess pain, and the 90 - point scale was used to assess the incidence of psychological symptoms. RESULTS The difference in pain assessment between the experimental and control groups was significant (p<0.001). The experimental group rated their childbirth pain as moderate (M=5.98), while the control group experienced severe pain (M=8.42). A significant difference in the incidence of psychological symptoms between groups was found in the dimensions of interpersonal sensitivity, hostility, phobic anxiety, and paranoid ideations (p=0.042; p=0.014; p=0.013; p=0.008). CONCLUSION This study demonstrated the impact of midwifery education and listening to classical music on the perception of childbirth pain and mental health in the puerperium. The experimental group rated childbirth pain significantly lower compared to the control group and had significantly fewer psychological symptoms 6 weeks after delivery.

Ukupno su kartirana 32 taksona (20 zimzelenih i 12 listopadnih). Poboljšano upravljanje zelenim otvorenim prostorom pulskog kampusa može rezultirati iznimno vrijednim ekološkim, društvenim i estetskim akademskim zelenim prostorom.

Abstract Extended-spectrum β-lactamases (ESBLs) hydrolyse extended-spectrum cephalosporins (ESC) and aztreonam. As ESBL-producing organisms have been identified in food producing animals, the aim of our study was to detect and analyse such Escherichia coli isolates from poultry. Antibiotic susceptibility of the isolates was determined with disk-diffusion and broth microdilution methods. ESBLs were detected with the double-disk synergy and inhibitor-based test with clavulanic acid. The transferability of cefotaxime resistance was determined with conjugation experiments, and genes encoding ESBLs, plasmid-mediated AmpC β-lactamases, and quinolone resistance determinants identified by polymerase chain reaction. The study included 108 faecal samples (cloacal swabs) from 25 different poultry farms in the Zenica-Doboj Canton, Bosnia and Herzegovina. Of these, 75 (69.4 %) were positive for E. coli, of which 27 were resistant to cefotaxime, amoxicillin, cefazoline, and cefriaxone, and susceptible to imipenem, meropenem, ertapenem, and amikacin. All 27 cefotaxime-resistant isolates were positive in double-disk synergy and combined disk tests. Eighteen isolates transferred cefotaxime resistance to E. coli recipient. Twenty-one isolates were positive for the blaCTX-M-1 cluster genes and seven for blaCTX-M-15. Fourteen were positive for the blaTEM genes. The most frequent plasmid incompatibility group was IncFIB, whereas IncFIA and Inc HI1 were present in only a few isolates. Two different sequence types (STs) were identified: ST117 and ST155. The emergence of ESBL-producing E. coli in farm animals presents a public health threat, as they can colonise the intestine and cause infections in humans.

Many recent research has focused on graphic design and shape of the packaging, and their effects on the customer's decision-making process as two separate categories. Since the shape of the packaging along with the graphic design plays an important role in the visual appearance of the packaging and attracts the customer's attention, the main objective of this research was to find out which packaging shapes and graphic elements customers find most attractive, as well as to understand the general opinion of customers about the influence of packaging aesthetics on their decision-making process when purchasing a product. Methodology of this research was conducted in two stages, from which the first one included creating three different graphic design solutions combined with three shape categories, and three variations of added value, for the same food packaging. The second part of the research covered an online questionnaire, in which a group of 50 people participated. This questionnaire focused on three variables: graphic design of the packaging, packaging shape and it’s added value. These variables were evaluated using the Likert scale. Through the questionnaire, participants were asked to answer general questions about the impact of the packaging visual appearance and added value, on their decision-making process when buying a product, as well as to choose the most appealing packaging between the given options. The research results showed that customers preferred non-standard packaging shapes and simple graphic design, as well as packaging with added value. The results of this research prove that the aesthetics of packaging has an impact on the customer's perception of a product, which means that packaging plays an important role in product marketing.
