Background/Aim. For the first time, we evaluated and presented the socio-demographic characteristics, clinical manifestations and laboratory findings of hospitalized coronavirus disease 2019 (COVID-19) patients from Canton Sarajevo, Bosnia and Herzegovina. Methods. This retrospective, single-centre study included 159 RT-PCR verified COVID-19 patients (92 mild/moderate; 67 severe/critical) consecutively hospitalized at the General Hospital "Prim. dr Abdulah Nakaš" in Sarajevo, Bosnia and Herzegovina. Socio-demographic, clinical, and laboratory data on admission were retrospectively obtained from each patient's electronic medical record and patient files by two experienced physicians. Results. 43.4% of the patients belonged to the age range of 46-65 years; 71.1% were men, and 68.6% had comorbidities; hypertension was the most prevalent comorbidity (100%), followed by diabetes (91.7%) and ischemic heart disease (35.8%). The leading clinical symptoms were fever (87.44%), tiredness (77.8%), and body/muscle aches (70.3%). There was significant reduction of blood oxygen saturation (p = 0.005), and significant elevation of D-dimer (p = 0.003), CRP (p = 0.044), and fasting plasma glucose (p = 0.047) in the severe/critical patients group compared to mild/moderate group. Conclusion. Older age, the male gender, confirmed comorbidities, decreased blood oxygen saturation, increased levels of CRP, D-dimer, and fasting plasma glucose, together with symptoms of chest pain/shortness of breath and/or diarrhea occurred more frequently in severe/critical than mild/moderate COVID-19 patients.

The purpose of this study was to explore possible protective effects of vitamin D3 on serum glucose concentration, body weight and histopathology of pancreas and liver. Animals were divided into 3 groups: Control group (n=6), streptozotocin (STZ) group (n=6) and streptozotocin + vitamin D3 (STZ+D3) group (n=6). Rats in the STZ+D3 group starting from the 7th day of experiment were given vitamin D3 for 14 days. Glucose levels and body weight were measured on the 1, 7, 14 and 21st day of experiment. Qualitative histological analysis of pancreas and liver was done using the light microscope with a digital camera. Differences between the groups were tested by one-way analysis of variance (ANOVA) followed by Dunnett's posttest. Differences in repeated measures were tested using paired t-test. On day 14 and 21, blood glucose level in STZ+D3 group was significantly higher compared to the control group of animals but significantly lower than the glucose level registered in STZ group of rats. On day 14 and day 21, body weight in STZ rats was significantly lower compared to weight in STZ+D3 and control groups of rats. Morphological changes, such as shrinkage of islets, vacuolation of both endocrine and exocrine cells, were observed in pancreas of STZ group of animals but were nearly absent in STZ+D3 rats. Similarly, STZ+D3 group of rats showed preserved liver histoarchitecture. Obtained results suggest that vitamin D3 treatment reduces hyperglycemia, exerts beneficial effects on body weight and alleviates histopathological changes in pancreas and liver in STZ-induced diabetic rats.

The aim of this paper is to determine the relationship between the quality of information from the Enterprise Resource Planning system (ERP system) and business performance. The quality of information from the ERP system is assessed using a survey questionnaire examining the end users of the ERP system, namely middle and top management because they use information from the ERP system to make business decisions. Business performance is monitored from a controlling point of view, using selected indicators from the DuPont system. Empirical research was conducted on medium and large enterprises in Bosnia and Herzegovina. The existence of a positive correlation between information quality and business performance was examined using regression analysis and correlation analysis. Regression analysis and correlation analysis indicate that return on sale (ROS) and return on assets (ROA) have a medium significant correlation with the quality of information, and total asset turnover ratio (TR) does not correlate with the quality of information. Based on the obtained results, a positive relationship between the quality of information from the ERP system and business performance was confirmed. This can be interpreted that information is becoming an increasingly important resource in supporting organizational activities, and information quality has been identified as one of the main determinants influencing the decision-making process.

The 2030 Agenda for Sustainable Development builds upon the Millennium Development Goals while at the same time reaffirming the conclusions of the leading instruments in the field of human rights and international law. The 17 integrated and indivisible sustainable development goals (SDGs) require innovation through digitalization and legal activities. Digitalization and new technologies are crucial for SDG 8, 9, and 16. SDG 16: Peace, justice, and strong institutions directly focus on law. While SDG 16 does not directly mention it, digitalization is essential in achieving its specific targets. Examples include concepts of e-government (including data protection and public access to information), e-commerce, equal access to dispute resolution mechanisms in cyberspace, and enforcement of non-discriminatory laws for sustainable development. The right to a healthy and sustainable environment encompasses economic, social, and environmental aspects that SDGs capture. To achieve these goals, the 2030 Agenda relies on international law instruments. The right to a healthy and sustainable environment is developing towards an internationally recognized human right. As environmental goals do not recognize national borders, international law plays a key role. International environmental law should facilitate a broader application of existing clean technologies through the transfer of technology and examine the development of new technologies as to its compatibility with a sustainable environment. Moreover, the human right to share in scientific advancement and enjoy its benefits embodies equal access to technology. The legal enforcement of sustainable goals in the private and governmental sectors remains one of the main concerns of climate change.

The question of a general part for EU Private International Law has attracted research and debate among PIL scholars long before the EU started to codify this legal field after the Amsterdam Treaty. However, the EU has made no attempt to make use of the existing research to adopt a comprehensive regulation of the general part of EU PIL and has adopted sector-specific regulation with inconsistent regulation of several general institutes. For the occasion of the anniversary of the Zeitschrift für Europarechtliche Studien this paper revisits the topic to answer the question which institutes of PIL should be codified in a general part of EU PIL. The conclusions are made based on four criteria: which general institutes of PIL are already regulated in the EU; are they generally applicable to all special parts of EU PIL; what is their practical relevance; and is there a need for their uniform regulation. The paper analyzes the discrepancies between existing general institutes of EU PIL and offers brief discussions on the possible formulation of some of the institutes for the general part.
