Aim of the study Most of the malignancies leading to obstructive jaundice are diagnosed too late when they are already advanced and inoperable, with palliation being the only treatment option left. Due to progressing hyperbilirubinaemia with its consequent adverse effects, biliary drainage must be established even in advanced malignancies. This study aims to investigate and analyse factors that affect clinical outcomes of percutaneous trans-hepatic biliary drainage (PTBD) in patients with obstructive jaundice due to advanced inoperable malignancy, and identify potential predictors of patient survival. Study design: Observational retrospective cohort study. Material and methods Baseline variables and clinical outcomes were evaluated in 108 consecutive patients treated with PTBD. The study’s primary endpoints were significant bilirubin level decrease and survival rates. Secondary endpoints included periprocedural major and minor complication rates and catheter primary and secondary patency rates. Results PTBD was technically successful and bile ducts were successfully drained in all 108 patients. Median serum bilirubin level, which was 282 (171-376) µmol/l before drainage, decreased significantly, to 80 (56-144) µmol/l, 15 days after stent placement (p < 0.001). Patient survival ranged from 3 to 597 days and the overall (median) survival time following PTBD was 168 days (90-302). The 1, 3, 6, 12 and 18-month survival rates were 96.3%, 75.9%, 48.1%, 8.3% and 1.9%, respectively. Multivariate analysis revealed that liver metastases and alkaline phosphatase were significantly associated with mortality. The overall complication rate was 9.3%. Conclusions PTBD is a safe and effective method to relieve jaundice caused by advanced inoperable malignant disease. Careful patient selection is necessary when introducing PTBD in order to avoid invasive procedures in patients with a poor prognosis.

This study aimed to analyze treatment guidelines of 12 SEE countries to identify non-pharmacological interventions recommended for schizophrenia, explore the evidence base supporting recommendations, and assess the implementation of recommended interventions. Desk and content analysis were employed to analyze the guidelines. Experts were surveyed across the 12 countries to assess availability of non-pharmacological treatments in leading mental health institutions, staff training, and inclusion in the official service price list. Most SEE countries have published treatment guidelines for schizophrenia focused on pharmacotherapy. Nine countries—Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Moldova, Montenegro, North Macedonia, and Serbia—included non-pharmacological interventions. The remaining three countries—Kosovo (UN Resolution), Romania, and Slovenia—have not published such treatment guidelines, however they are on offer in leading institutions. The median number of recommended interventions was seven (range 5–11). Family therapy and psychoeducation were recommended in most treatment guidelines. The majority of recommended interventions have a negative or mixed randomized controlled trial evidence base. A small proportion of leading mental health institutions includes these interventions in their official service price list. The interventions recommended in the treatment guidelines seem to be rarely implemented within mental health services in the SEE countries.

During 2019, 28 grave constructions were excavated at cemetery Metaljica (Hadzici municipality, Bosnia and Herzegovina). Archaeological excavation have revealed 17 well preserved skeletons that were subjected to anthropological, odontological and genetic analyses. To determine sex by genetic analysis, amelogenin and DYS391 loci were taken into consideration. Concordance between results of anthropological, odontological and genetic analyses applied in this research occurred in one sample out of 17. In four samples, sex was determined only by genetic analysis, since sexual dimorphism indicators were not preserved. Concordance between odontological and genetic determinations was observed in two samples, while affirmative results of anthropological and genetic analysis were obtained in only one sample. Discrepancy in the majority of samples can be atributted to the state of preservation of skeletal remains, interpopulation differences and allele drop-out. Moreover, anthropological and odontological analyses were not applicable to juvenile/subadult skeletons, since sexually dimorphic characteristics relevant for metric and morphological analysis are not developed well at that developmental period. This study emphasizes the importance of combining anthropological, odontological and genetic methods in order to determine sex of archaeological skeletal remains accurately.

This issue, 75/1 is mostly dedicated to the environmental impact of landslides, which, due to current climate change, are becoming more and more pronounced around the world and in the Republic of Croatia. The six papers (BOSTJANČIĆ et al., 2022, Fig. 1 poly­ gon 1; FILIPOVIĆ et al., 2022, Fig. 1 polygon 2; FRANGEN et al., 2022, Fig. 1 polygon 3; GULAM et al., 2022, Fig. 1 polygon 4; PODOLSZKI et al., 2022, Fig. 1 polygon 5; POLLAK et al., 2022, Fig. 1 polygon 6) focusing on landslides are the result of the work of a large team of people from the Croatian Geological Sur­ vey, carried out within the framework of the safEarth project, cofinanced by the ERDF and IPA II funds of the European Union. As a part of the Interreg IPA – Cross-border Cooperation Programme Croatia – Bosnia and Herzegovina – Montenegro 2014-2020, the safEarth project was based on cross-border coop­ eration of four partner institutions, namely the Croatian Geological Survey (lead partner), Geological Survey of Montenegro, Faculty of Mining, Geology and Civil Engineering of the Univer­ sity of Tuzla and the Development Agency Žepče d.o.o. The main project activities were focused on landslide susceptibility maps (LSM) as one of the most important data sets in spatial planning The use of high-resolution LiDAR scanning in the research of small landslides based on Croatian examples

Skin lesions can be an early indicator of a wide range of infectious and other diseases. The use of deep learning (DL) models to diagnose skin lesions has great potential in assisting clinicians with prescreening patients. However, these models often learn biases inherent in training data, which can lead to a performance gap in the diagnosis of people with light and/or dark skin tones. To the best of our knowledge, limited work has been done on identifying, let alone reducing, model bias in skin disease classification and segmentation. In this paper, we examine DL fairness and demonstrate the existence of bias in classification and segmentation models for subpopulations with darker skin tones compared to individuals with lighter skin tones, for specific diseases including Lyme, Tinea Corporis and Herpes Zoster. Then, we propose a novel preprocessing, data alteration method, called EdgeMixup, to improve model fairness with a linear combination of an input skin lesion image and a corresponding a predicted edge detection mask combined with color saturation alteration. For the task of skin disease classification, EdgeMixup outperforms much more complex competing methods such as adversarial approaches, achieving a 10.99% reduction in accuracy gap between light and dark skin tone samples, and resulting in 8.4% improved performance for an underrepresented subpopulation.

U testu provenijencija hrasta lužnjaka (Quercus robur L.) u Bosni i Hercegovini koji je osnovan 2009. godine istraživana je varijabilnost visina biljaka i promjera vrata korijena na biljkama iz 27 provenijencija. Osim toga, analizirane su i korelacije između visina stabala i promjera vrata korijena s morfološkim svojstvima listova iz prirodnih populacija. Sjeme za osnivanje testova provenijencija, kao i listovi koji su korišteni u morfometrijskoj analizi, sakupljeni su u istim populacijama. Provedenim istraživanjima utvrđene su statistički značajne razlike za svojstvo visine i promjera vrata korijena. Varijabilnost je potvrđena i Duncan-ovim testom, i to na način da su biljke s obzirom na svojstvo visina grupirane u 11 skupina te s obzirom na svojstvo promjer vrata korijena u četiri skupine. Klasterskom analizom nije utvrđeno grupiranje populacija s obzirom na geografske i ekološke udaljenosti populacija. Korelacijskom analizom potvrđena je statistički značajna povezanost između visine biljaka i promjera vrata korijena te između morfoloških svojstava listova i visine biljaka i promjera vrata korijena. Dobiveni rezultati upućuju na to da se na temelju određenih morfoloških svojstava može provoditi selekcija provenijencija u mlađim fazama razvoja.

Simple Summary In order to prevent lamb distress during weaning and avoid the occurrence of oxidative stress leading to diminished production performance, health status, or product quality, feeds rich in polyphenols (anthocyanins) are increasingly used in ruminant feeding. In the present study, lambs were allocated into three groups, with 10 lambs per group. The feed mixture for the control group (C) contained yellow corn. Lambs in experimental group I were fed feed mixtures containing yellow corn replaced by red corn at 50% (RC50). In experimental group II, red corn fully replaced (100%) yellow corn (RC100) in the lambs’ feed. The results of the present study indicate a positive effect of red corn rich in anthocyanins on the metabolic profile without any changes in the productive traits of lambs. Abstract In this study, we aimed to evaluate the effects of different proportions of red corn rich in anthocyanins on the diet of fattening lambs considering their productive traits, blood metabolic profile, and antioxidative status. The research was carried out with 30 Merinolandschaf lambs, 90 days old and weaned. The feed mixture for lambs (n = 10) of the control group contained yellow corn, while in the feed mixture of experimental group I (n = 10), yellow corn was replaced with red corn at 50% (RC50), and in experimental group II (n = 10), yellow corn was 100% replaced with red corn (RC100). An automatic three-part differential haematology analyser was used to determine haematological parameters in whole blood, and biochemical parameters were determined in blood serum using a biochemical analyser. A diet containing red corn did not affect productive traits or the majority of the examined parameters. However, higher blood haemoglobin content, increased aspartate aminotransferase and creatine kinase activity, and decreased glucose and non-esterified fatty acids concentrations were found in the serum of RC100 lambs. These results indicate a positive effect of red corn rich in anthocyanins on the metabolic profile without any changes in the productive traits of lambs.

The goal of this research is development, design and manufacturing of CNC milling machine prototype using standard aluminium profiles. Machine is a three axis’s machine and it is developed primarily for education in the field of wood machining. It can be used also for machining of light metal parts. Main initial goal of the machine development was the low cost for its manufacturing. To achieve this goal, rapid prototyping technology was used to manufacture most of the machine parts. In addition, a lot of standard parts are used. The detail methodology for machine development, design and manufacturing are shown in this paper. Design process includes development of CAD models, calculation of all necessary critical parts, selections of materials and development of machine subassemblies and assemblies.

The goal of this part of the study was to optimize the sequencing procedure for 16 human genes and their regulatory regions that might be associated with differential immunological response to COVID-19. The study was performed on 60 COVID-19 patients from the General Hospital of Tešanj, Bosnia and Herzegovina, categorized into three groups of mild, moderate, and severe clinical manifestation, based on the diagnosis by the residential physician. Target coding sequences and their regulatory regions were amplified for the following genes: HLA-A, HLA-B, HLA-C, ACE2, IL-6, IL-4, TMPRSS2, IFITM3, IL-12, RIG-I/DDX58, IRF-7, IRF-9, IL-1B, IL-1A, CD55, and TNF-α. DNA was isolated from the whole blood samples stored at -20°C for six months using QIAamp® DNA Mini Kit according to manufacturer’s instructions. Since NGS analysis of target genomic regions was performed on the Ion Torrent GeneStudio™ S5 platforms, libraries were prepared using Ion AmpliSeq™ Library Kit Plus according to manufacturer’s instructions in a protocol optimized for low-quality DNA. Due to dissatisfactory sequencing results, further protocol optimization steps were employed through separating two primer pools, increasing the number of PCR cycles, and decreasing the annealing temperature for the primer pool which showed poorer amplification results. In the end, 36 samples produced optimal results, while the remaining 24 samples will be re-sequenced following repeated sample collection and DNA isolation, accompanied by additional protocol modifications.

Background Bosnia and Herzegovina is among ten countries in the world with the highest mortality rate due to COVID-19. Lack of lockdown, open borders, high mortality rate, no vaccination plan, and strong domestic anti-vaccination movement present serious COVID-19 concerns in Bosnia and Herzegovina. In such circumstances, we set out to study 1) the willingness of general public to receive the vaccine, 2) factors that affect vaccine rejection, and 3) motivation for vaccine acceptance. Methods A cross-sectional study was conducted among 10471 adults in Bosnia and Herzegovina to assess the acceptance or rejection of participants toward COVID-19 vaccination. Using a logistic regression model, we examined the associations of sociodemographic characteristics with vaccine rejection, reasons for vaccine hesitancy, preferred vaccine manufacturer, and information sources. Results Surprisingly, only 25.7% of respondents indicated they would like to get a COVID-19 vaccine, while 74.3% of respondents were either hesitant or completely rejected vaccination. The vaccine acceptance increased with increasing age, education, and income level. Major motivation of pro-vaccination behavior was intention to achieve collective immunity (30.1%), while the leading incentive for vaccine refusal was deficiency of clinical data (30.2%). The Pfizer-BioNTech vaccine is shown to be eightfold more preferred vaccine compared to the other manufacturers. For the first time in Bosnia, vaccine acceptance among health care professionals has been reported, where only 39.4% of healthcare professionals expressed willingness to get vaccinated. Conclusion With the high share of the population unwilling to vaccinate, governmental impotence in securing the vaccines supplies, combined with the lack of any lockdown measures suggests that Bosnia and Herzegovina is unlikely to put COVID-19 pandemic under control in near future.

The focus of research presented in this paper is quantification of the relationship between the traffic safety and roadside advertising structures along a selected road in urban environment. In order to determine correlation, statistical analysis of traffic safety indicators was performed. Then identificcation of characteristics of advertising structures and analysis was done by using multi-criteria evaluation in order to determine their impact on driver distraction. Determination of driver distraction was performed by testing the drivers in real traffic conditions, using specialized measuring equipment. The indicators derived from the research were then analyzed using the methods of regression analysis, and safety.

Abstract Historically, two angel shark species, common angel shark Squatina squatina and smoothback angel shark Squatina oculata, were common in the upper continental shelf of the eastern Adriatic Sea. Although both species are considered critically endangered in the Adriatic and the rest of the world, there are almost no data on the current status of populations, threat assessment and species-specific in-situ conservation. Common angel shark is still present in highly fragmented areas of the eastern Adriatic with extremely rare but consistent records, while smoothback angel shark is mostly considered regionally extinct in the Adriatic due to overfishing and overuse of non-selective fishing gear. There have been only 3 published records of common angel shark this century, the last two of which were reported by fishermen. This paper presents data on 34 new finds, including neonates, juveniles, subadults and adults recorded between January 2020 and August 2021 in the Zadar-Šibenik archipelago (central Adriatic) and one in Premantura (northern Adriatic). Two are original findings during the field expedition, 9 were reported directly by local fishermen, while 23 were reported through a detailed questionnaire. Additionally, plausible breeding and/or nursery grounds between Zadar and Šibenik are discussed with their importance for revitalization and long-term conservation in situ.

Meeting sustainable food production challenges requires efficient ways to manage nutrients and mitigate the losses of nitrogen (N) and phosphorus (P) to water. Future nutrient management therefore requires a clearer understanding of the relative influence of soils, geology, farm practice, landscape and weather on the propensity for nutrients to be lost to water. Within the Agricultural Catchments Programme (ACP), environmental, agronomic and socioeconomic data have been gathered since 2009, using the same experimental methodology in five meso-scale river catchments, and one karst spring zone, covering a range of soils, landscapes and farming systems. The ACP has contributed to a better understanding of nutrient mobilisation and transfer pathways and highlighted the influence of the physical and chemical environment as well as agricultural and meteorological drivers on diffuse nutrient loss to ground and surface waters. The environmental quality standards were breached for N and/or P in some of the catchments, but for different reasons and not always clearly linked to the source pressures within the catchment. There are clearly no one-size-fits-all solutions for mitigation of nutrient losses to water. A better understanding of the underlying processes is required to identify critical source areas, to select mitigation strategies, when to implement them and to build realistic expectations of their impact. Sustainability in an agricultural setting is not confined to environmental issues, but also includes social, economic and innovative aspects. To maximise farmers’ uptake of environmental measures, the actions should encompass all these aspects of sustainability. Integrated knowledge transfer is key.
