Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory autoimmune disease in childhood, significantly contributing to both short- and long-term disability. While certain human leukocyte antigen (HLA) class II alleles are known to be associated with specific subgroups of JIA, emerging evidence suggests a strong correlation between these alleles and treatment response. This study involved 143 JIA patients diagnosed according to International League of Associations for Rheumatology criteria. Each patient underwent HLA class II typing, including HLA-B27, as well as tests for rheumatoid factor (RF) and antinuclear antibodies (ANA). Comprehensive rheumatological assessments were conducted at diagnosis, with follow-ups at three and six months post-onset. After six months of methotrexate (MTX) treatment, patients were categorized as responders or non-responders. Responders achieved clinically inactive disease based on the American College of Rheumatology Provisional Criteria for Defining Clinical Inactive Disease and Clinical Remission. Non-responders, who did not reach clinically inactive disease after six months of treatment, required the addition of another non-biological disease-modifying antirheumatic drug (DMARD) or a biological DMARD. Our analysis revealed that the HLA-DRB1*01 allele is a significant prognostic marker for therapeutic response, predicting therapeutic resistance (P ═ 0.01). The most prevalent HLA-DRB1 alleles in the treatment-resistant group were HLA-DRB1*08:11 (11.3%), HLA-DRB1*01:01 (8.5%), HLA-DRB1*01:13, HLA-DRB1*04:11 (7%), HLA-DRB1*08:13, and HLA-DRB1*08:15 (4.2%). These findings highlight the critical role of HLA class II alleles in pediatric rheumatology, particularly in relation to treatment response and disease prognosis. In the era of personalized medicine, understanding the genetic contributions to treatment response and outcomes in JIA patients is essential. A key limitation of this study was the lack of comparison of treatment responses across different JIA subtypes. Future studies should prioritize evaluating MTX efficacy within specific JIA subgroups to enable a more tailored understanding of its effectiveness.

Hrast kitnjak (Quercus petraea (Matt.) Lieblein) jedna je od ekonomski i ekološki vrlo važnih vrsta šumskog drveća i javlja se u oko 15% svih šuma u Bosni i Hercegovini. Prirodne populacije hrasta kitnjaka u Bosni i Hercegovini predstavljaju specifične zajednice koje se razlikuju od jedinki iz svog optimuma u zapadnoj, južnoj i istočnoj Europi, te predstavljaju genetičke specifikume bitne za očuvanje biološke raznolikosti hrasta kitnjaka u Europi. Istraživanjem morfoloških svojstava listova željelo se utvrdi stupanj unutarpopulacijske i međupopulacijske varijabilnosti hrasta kitnjaka na području Bosne i Hercegovine, te veze između variranja populacija u fenotipskim svojstvima i geoklimatskih čimbenika. Rezultati istraživanja bit će iskorišteni prilikom odabira mjera za očuvanje ove vrste šumskog drveća. Analizirano je 13 svojstava listova hrasta kitnjaka, sakupljenih sa 237 stabala iz 24 prirodne populacije. Rezultati su pokazali da su koeficijenti varijacije za sva mjerena svojstava u rasponu od 13.3% za duljinu plojke, do 26.5% za duljinu peteljke. Analiza varijance (ANOVA) otkrila je postojanje fenotipskih varijacija unutar i među populacijama. Varijacija unutar populacija bila je prosječno 28.44% i veća nego između populacija (prosječno 16.2%). Klaster analiza pokazala je razdvajanje populacija u dva glavna klastera, gdje su jednom klasteru pripale populacije Jajce Komotin i Fojnica, a drugom klasteru sve ostale populacije. Većina analiziranih svojstava lista (osim duljine peteljke, omjera širine i duljine lista i broja režnjeva) bila je u korelaciji sa geografskom širinom, srednjom temperaturom kvartala s najviše padalina i količinom padalina u najtoplijem kvartalu. Ovi rezultati mogu biti korišteni za očuvanje raznolikosti i upravljanje resursima hrasta kitnjaka u budućnosti.

Hepatic steatosis, a key factor in chronic liver diseases, is difficult to diagnose early. This study introduces a classifier for hepatic steatosis using microwave technology, validated through clinical trials. Our method uses microwave signals and deep learning to improve detection to reliable results. It includes a pipeline with simulation data, a new deep-learning model called HepNet, and transfer learning. The simulation data, created with 3D electromagnetic tools, is used for training and evaluating the model. HepNet uses skip connections in convolutional layers and two fully connected layers for better feature extraction and generalization. Calibration and uncertainty assessments ensure the model's robustness. Our simulation achieved an F1-score of 0.91 and a confidence level of 0.97 for classifications with entropy ≤0.1, outperforming traditional models like LeNet (0.81) and ResNet (0.87). We also use transfer learning to adapt HepNet to clinical data with limited patient samples. Using 1H-MRS as the standard for two microwave liver scanners, HepNet achieved high F1-scores of 0.95 and 0.88 for 94 and 158 patient samples, respectively, showing its clinical potential.

INTRODUCTION AND AIM Weight-adjusted waist index (WWI) represents a novel anthropometric measure for assessing obesity. Bearing in mind that there is insufficient data in the literature regarding gender differences in WWI values, the aim of the current study was to examine gender differences in WWI values among older adults.

The highest representative of the judicial authority and one of the most im- portant levers in the administrative apparatus of the Ottoman Empire in one province (eyalet) was the molla. He was granted extensive powers and the ability to control other officials of the Ottoman authority. Considering the role and importance of those high-ranking Ottoman officials, the paper aims to present the individuals who were appointed to the Eyalet of Bosna as well as the dynamics of changes in these positions in the second half of the 17th century. In cases where it was possible, insight was given into their education and experience, as well as some interesting facts from their lives. In order to achieve this, the contents of various individual and collective documents were analyzed. The presented data contribute to a better understanding of Ottoman judicial practice and the specific activities of judges in Bosnia in the 17th century.

Improper nutrition leads to changes in the body that are not only an aesthetic problem, but also lead to chronic diseases. The goals of the research are to analyze knowledge, habits and attitudes about nutrition and knowledge about obesity, to determine the body mass index (BMI) of all respondents, to analyze the connection between nutrition, excess body weight and the frequency of chronic non-communicable diseases. The study was cross-sectional epidemiological, descriptive-analytical, was conducted on a sample of 200 respondents of patients Family medicine, Public Health Center of the Sarajevo Canton. The survey was conducted by interviewing respondents using a modified questionnaire, made up of 27 questions. Analyzing the results, it was determined that the respondents' knowledge of nutrition is satisfactory, but that the majority of respondents (121) have a BMI over 25. For men in the age group of 46-55 years, the average BMI is 29.3, and for women in the same age group, it is 27. 5, which shows that they do not apply their own knowledge about nutrition. The majority of respondents (32%) whose BMI is over 25 have one or more chronic non-communicable diseases. Most respondents stated that they get information about proper nutrition through the media, although many of them suffer from some chronic diseases, they do not get information at the health center. In the family doctor's clinic, it is very important to recognize excess body weight, bad eating habits of patients in time, plan a prevention strategy, and prevent the further development of chronic diseases with professional counseling.

Background: High hypericin-loaded polyvinylpyrrolidone (HHL-PVP) constitutes a novel approach to utilize the promising characteristics of hypericin for photodynamic diagnosis (PDD) and therapy (PDT) of brain tumors in an orally bioavailable formulation. The aim of this study was to investigate the ability of a Complementary Metal-Oxide-Semiconductor (CMOS) camera-based fluorescence imaging system to selectively visualize HHL-PVP in glioblastoma tissue even in the presence of 5-Aminolvevulinic acid (5-ALA) induced fluorescence, which is widely utilized in brain tumor surgery. Methods: We applied a previously established system with a non-hypericin specific filter for 5-ALA fluorescence visualization and a newly introduced hypericin-specific filter at 575–615 nm that transmits the spectrum of hypericin, but not 5-ALA fluorescence. Glioblastoma specimens obtained from 12 patients (11 with preoperative 5-ALA intake) were ex vivo incubated with HHL-PVP. Subsequently, fluorescence intensity and lifetime changes using both the non-hypericin specific filter and hypericin-specific filter were measured before and after HHL-PVP incubation and after subsequent rinsing. Results: While no significant differences in fluorescence signal were observed using the non-hypericin specific filter, statistically significant increases in fluorescence intensity (p = 0.001) and lifetime (p = 0.028) after HHL-PVP incubation were demonstrated using the hypericin-specific filter. In consequence, specimens treated with HHL-PVP could be identified according to the fluorescence signal with high diagnostic sensitivity (87.5%) and specificity (100%). Conclusions: Our CMOS camera-based system with a hypericin-specific filter is capable of selectively visualizing hypericin fluorescence in glioblastoma tissue after ex vivo HHL-PVP incubation. In the future, this technique could facilitate clinical investigations of HHL-PVP for PDD and PDT while maintaining the current standard of care with 5-ALA guidance.

Regulatorna tijela Bosne i Hercegovine koja su se pojavila u posljednjih dvadesetak godina u procesu intenzivne agencifikacije i u toj državi većinom su neistražena pojava. Stoga je cilj ovoga rada utvrditi koje su od velika broja agencija te države regulatori, kakve imaju ovlasti i neovisnost, kojem komparativnom modelu pripadaju, a posebice postoji li uopće model bosanskohercegovačkog regulatora. S tom su svrhom uspoređeni regulatorni modeli određenih država od posebne važnosti i analizirana pitanja neovisnosti i sadržaja regulatornih ovlasti. Utvrđeno je postojanje sedam regulatornih agencija na središnjoj razini vlasti te da je većina bosanskohercegovačkih regulatora dio državne uprave. Osim toga, neovisnost pojedinih regulatora jako varira – od relativno visoke u području energije i komunikacija do niske u reguliranju željezničkog prometa, pri čemu pojedini regulatori imaju različite uzore, od angloameričkih do europskokontinentalnih, te je konačan zaključak da model bosanskohercegovačkog regulatora uopće ne postoji.
