Background: Hyperglycemia, polyuria, and glycosuria are all risk factors for the frequency of urinary tract infections in patients with diabetes. Objective: The aim of this study is to establish correlation between inflammatory and biochemical parameters in patients with diabetes and urinary tract infection. Methods: Total number 116 patients were monitored, at the ages between 18-95 years, with diabetes and urinary tract infection, of which 59.49% women and 40.51% men. Patients were with a duration of diabetes from 0 to over 20 years, with an average fasting glycemia of 9.54 mmol/l, and postprandial glycemia 13.94 mmol/l, HbA1C 9.92%, which have been poorly regulated in the last 3-4 months. Inflammatory parameters SE, CRP, leukocytes were correlated with inflammatory parameters of urine sediment and positive urine cultures. Results: Average values of urea, creatinine, and proteinuria were positively correlated with the duration of diabetes. Escherichia coli, Enterococcus feecalis, and Candida albicans were the most common pathogens isolated in urine culture, 51 patients had reinfection once, 39 patients had two reinfections, and 26 patients had three reinfections during the 6-month follow-up. Conclusion: Duration of diabetes, long-term poor glycoregulation lead to microangiopathic changes in the kidneys in the form of diabetic nephropathy with retention of nitrogenous substances of urea, creatinine with proteinuria, and acute hyperglycemia, polyuria and glycosuria, further leading to frequent urinary tract infections.

Background: The etiology of preeclampsia has still not been completely explained. Early identification of women with the risk of developing preeclampsia is a key goal of antenatal care. Objective: To investigate risk factors for preeclampsia from the history, laboratory and ultrasound findings (Doppler). Methods: Pregnant women with normal Doppler sonography in the second trimester of pregnancy were classified as a control group, while pregnant women with impaired Doppler in the second trimester were considered as the investigated group with presumably increased risk for preeclampsia. A total number of 80 patients was included in the study (40 patients in each group). Results: The difference of urea, uric acid and lactate dehydrogenase (LDH) in the serum of the control and investigated group was statistically significant, while the differences were not statistically significant for creatinine, aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The presence of a notch sign during assessment of blood flow in uterine arteries in subjects in the investigated group with the diagnosis of preeclampsia had the specificity of 47.62%, and sensitivity of 88.89%. The positive predictive value of a notch sign during assessment of blood flow in uterine arteries as a marker for diagnosis of preeclampsia in the second trimester of pregnancy was 90.91%, and its negative. Systolic and diastolic blood pressure are dependent variables which are predicting preeclampsia, whilst a notch sign in uterine arteries was designated as an independent variable predicting preeclampsia. Conclusion: From the laboratory tests the following parameters were considered as the risk factors for preeclampsia: increasing levels of urea, uric acid, and LDH. Notch sign was considered to be a very strong predictor of preeclampsia, especially if present bilaterally. Doppler sonography in the second trimester of pregnancy is a good predictor for early diagnosis of preeclampsia.

The sense of sight plays a very important role in the life of every individual, since we receive most of the information from the environment with the help of sight. Visually impaired children have difficulty receiving information from the world around them. Lack of visual experience can negatively affect their development. Timely examinations and assessments will indicate the occurrence of various neurological disorders in children, if any are present. A very common cause of neurological disorders is perinatal brain damage. Children with perinatal brain damage often have difficulties in visual functioning and it is therefore very important to assess functional vision in these children. If there are any neurodevelopmental disorders in the child, it is important to start vision rehabilitation as soon as possible, in order to effectively influence the improvement of visual functions. Keywords: functional vision, perinatal brain damage, early vision rehabilitation.

A synoptic overview of scientific methods applied in bone and associated research fields across species has yet to be published. Experts from the EU Cost Action GEMSTONE (“GEnomics of MusculoSkeletal Traits translational Network”) Working Group 2 present an overview of the routine techniques as well as clinical and research approaches employed to characterize bone phenotypes in humans and selected animal models (mice and zebrafish) of health and disease. The goal is consolidation of knowledge and a map for future research. This expert paper provides a comprehensive overview of state-of-the-art technologies to investigate bone properties in humans and animals – including their strengths and weaknesses. New research methodologies are outlined and future strategies are discussed to combine phenotypic with rapidly developing –omics data in order to advance musculoskeletal research and move towards “personalised medicine”.

Abstract Background: In a contemporary fast-changing world, companies are facing growing global competition, volatile markets, altered workforce structure, and another technological reshifting, which generates enormous pressure on them to improve their business performance and imposes the necessity to highlight practices of talent management more seriously. Objectives: In this study we explore interrelations between attraction/work motivational factors and talent retention, observed through talent engagement. Methods/Approach: The methodology in this research focuses on the comprehensive resource-based view and encompasses quantitative analysis based on data gathered from talented managers in Bosnia and Herzegovina. Results: The research results unveiled that talents were attracted to work for current companies primarily because of: good salary and company goodwill. The top three prevalent work motivational factors for talents included: (1) comfortable work environment, (2) enough autonomy and creativity in working and deciding, and (3) work-life balance. Furthermore, talent motivational factors related to talent retention in a statistically significant positive way. Conclusions: This study furnishes available talent research and theory by relating attraction/work motivational factors to talent engagement; and by introducing the fundamental motivational factors which are of monumental importance for retaining talented managers in Bosnia and Herzegovina.

Abstract The Balkan Peninsula and the Dinaric Mountains possess extraordinary biodiversity and support one of the largest and most diverse wolf (Canis lupus) populations in Europe. Results obtained with diverse genetic markers show west‐east substructure, also seen in various other species, despite the absence of obvious barriers to movement. However, the spatial extent of the genetic clusters remains unresolved, and our aim was to combine fine‐scale sampling with population and spatial genetic analyses to improve resolution of wolf genetic clusters. We analyzed 16 autosomal microsatellites from 255 wolves sampled in Slovenia, Croatia, Bosnia and Herzegovina (BIH), and Serbia and documented three genetic clusters. These comprised (1) Slovenia and the regions of Gorski kotar and Lika in Croatia, (2) the region of Dalmatia in southern Croatia and BIH, and (3) Serbia. When we mapped the clusters geographically, we observed west‐east genetic structure across the study area, together with some specific structure in BIH–Dalmatia. We observed that cluster 1 had a smaller effective population size, consistent with earlier reports of population recovery since the 1980s. Our results provide foundation for future genomic studies that would further resolve the observed west‐east population structure and its evolutionary history in wolves and other taxa in the region and identify focal areas for habitat conservation. They also have immediate importance for conservation planning for the wolves in one of the most important parts of the species’ European range.

In the Roman legal tradition, but also in modern civil law systems, the term commorientes (lat. commorientes) refers to persons who died in the same accident or other danger, standing in a legal position relevant to inheritance law. In connection with the resolution of such situations in the theory of private law, various legal presumptions have been developed since the period of classical Roman law. All these presumptions can be systematized within two basic concepts - the first based on the presumption of survival of subjects and the second based on the presumption of the simultaneous death of subjects. Comparatively, in the development of European private law, there has been a reception of both concepts, with the proviso that over time the concept of simultaneity will almost completely suppress the concept of survival. The paper analyzes the reasons for this. In establishing a link between Roman roots and European private law, special attention is given to the possibility of applying presumptions in cases where there is a certain spatial or temporal distance between the deaths of persons or if a different cause has led to fatal consequences. Ultimately, the paper clearly points to the importance of Roman rules, which can sometimes be fundamental in understanding the institutes of contemporary private law.

Institute for Mathematics and Democracy The Institute for Mathematics and Democracy (IMD)1 was created to help cast light on the important role that mathematics plays in our political systems. Founded in 2019, it is housed at Wellesley College, a liberal arts institution with a strong interest in interdisciplinary work. The mission of IMD is to promote a deeper understanding of the mathematics that underlies many socioeconomic forces and political processes so that citizens can make informed political decisions and effect meaningful change. It supports research, teaching, and outreach in mathematics and democracy, and brings together educators and activists who recognize the importance of political quantitative literacy. It acts as a facilitator, a repository, and nexus to bring research and pedagogy of disparate individuals who synthesize mathematics and democracy in their research and teaching. The timeliness of these efforts is apparent as IMD is finding a wide and growing audience among students, researchers, educators, activists, and the public at large. Over thirty mathematicians now serve as scholars and affiliates for IMD, many of whom have pursued or supervised research, run summer programs, or created curricula at the intersection of politics and mathematics. The institute has also supported over twenty student researchers, almost half of them from underrepresented groups. The activities of IMD are rooted and motivated by mathematics, but they lie at the unique interdisciplinary interface of mathematics, statistics, political science, economics, and history. Not only do they fill an evident educational and research gap, but they serve a social purpose: political

Recent years have seen a surge in popularity of concession projects, particularly in certain sectors such as energy, mining, and geological explorations. These projects are not only significant and beneficial for the investors, but they are also boosting local economies. The very foundation of such projects is the concession contract (CC)—contract with both public and private law elements determining the relations between the state organ issuing the concession and the private entity. This paper will focus on the case of Bosnia and Herzegovina (B&H) where CCs are often unbalanced and commonly unilaterally designed by the state party that dictates all of its provisions. Consequently, the private party is placed in a difficult, take-it-or-leave-it situation if it does not want to accept the CC as drafted by the state party. Potential steps toward the implementation of World Commerce & Contracting Principles (WCC Principles) in the CCs in B&H shall be presented, along with their predictable benefits and likely impact on the shortening and balancing the process of negotiating the CC in B&H.

Brain parenchyma infiltration with glioblastoma (GB) cannot be entirely visualized by conventional magnetic resonance imaging (MRI). The aim of this study was to investigate changes in the energy and membrane metabolism measured with phosphorous MR spectroscopy (31P-MRS) in the presumably “normal-appearing” brain following chemoradiation therapy (CRT) in GB patients in comparison to healthy controls. Twenty (seven female, thirteen male) GB patients underwent a 31P-MRS scan prior to surgery (baseline) and after three months of standard CRT (follow-up examination. The regions of interest “contrast-enhancing (CE) tumor” (if present), “adjacent to the (former) tumor”, “ipsilateral distant” hemisphere, and “contralateral” hemisphere were compared, differentiating between patients with stable (SD) and progressive disease (PD). Metabolite ratios PCr/ATP, Pi/ATP, PCr/Pi, PME/PDE, PME/PCr, and PDE/ATP were investigated. In PD, energy and membrane metabolism in CE tumor areas have a tendency to “normalize” under therapy. In different “normal-appearing” brain areas of GB patients, the energy and membrane metabolism either “normalized” or were “disturbed”, in comparison to baseline or controls. Differences were also detected between patients with SD and PD. 31P-MRS might contribute as an additional imaging biomarker for outcome measurement, which remains to be investigated in a larger cohort.

Columnar microstructures are critical for obtaining good resistance switching properties in SiO x resistive random access memory (ReRAM) devices. In this work, the formation and structure of columnar boundaries are studied in sputtered SiO x layers. Using TEM measurements, we analyze SiO x layers in Me–SiO x –Mo heterostructures, where Me = Ti or Au/Ti. We show that the SiO x layers are templated by the Mo surface roughness, leading to the formation of columnar boundaries protruding from troughs at the SiO x /Mo interface. Electron energy-loss spectroscopy measurements show that these boundaries are best characterized as voids, which in turn facilitate Ti, Mo, and Au incorporation from the electrodes into SiO x . Density functional theory calculations of a simple model of the SiO 2 grain boundary and column boundary show that O interstitials preferentially reside at the boundaries rather than in the SiO 2 bulk. The results elucidate the nature of the SiO x microstructure and the complex interactions between the metal electrodes and the switching oxide, each of which is critically important for further materials engineering and the optimization of ReRAM devices.

Abstract Community mobility involves walking with physical and cognitive challenges. In older adults (N=116; results here from initial analyses: N=29, Age=75±5 years, 51% females), we assessed gait speed and smoothness (harmonic-ratio) while walking on even and uneven surfaces, with or without an alternate alphabeting dual-task (ABC). ANOVA assessed surface and dual-task effects; Pearson correlations compared gait with global cognition and executive function composite z-scores. The four conditions (even, uneven, even-ABC and uneven-ABC) affected speed(m/s) (0.97±0.14 vs 0.90±0.15 vs 0.83±0.17 vs 0.79±0.16). Smoothness (2.19±0.48 vs 1.89±0.38 vs 1.92±0.53 vs 1.7±0.43) was affected by only surface (controlled for speed). Greater speed was associated with better global cognition(ρ=0.47 to 0.49, p<0.05) for all conditions and with better executive function for even-ABC(ρ=0.39, p=0.04) and uneven-ABC(ρ=0.40, p=0.03). Executive function was associated with smoothness during even(ρp=-0.42, p=0.03) and uneven(ρp=-0.39, p=0.04) walking. Type of walking challenge differentially affects gait quality and associations with cognitive function.

Dual-task balance studies explore interference between balance and cognitive tasks. This study is a descriptive analysis of accelerometry balance metrics to determine if a verbal cognitive task influences postural control after the task ends. Fifty-two healthy older adults (75 ± 6 years old, 30 female) performed standing balance and cognitive dual-tasks. An accelerometer recorded movement from before, during, and after the task (reciting every other letter of the alphabet). Thirty-six balance metrics were calculated for each task condition. The effect of the cognitive task on postural control was determined by a generalized linear model. Twelve variables, including anterior–posterior centroid frequency, peak frequency and entropy rate, medial-later entropy rate and wavelet entropy, and bandwidth in all directions, exhibited significant differences between baseline and cognitive task periods, but not between baseline and post-task periods. These results indicate that the verbal cognitive task did alter balance, but did not bring about persistent effects after the task had ended. Traditional balance measurements, i.e., root mean square and normalized path length, notably lacked significance, highlighting the potential to use other accelerometer metrics for the early detection of balance problems. These novel insights into the temporal dynamics of dual-task balance support current dual-task paradigms to reduce fall risk in older adults.

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.
