Abstract The Logistics Performance Index (LPI) performed by the World Bank is an indicator of the logistics environment quality of a country in which logistics operators act. The LPI is an interactive tool designed to help countries identify challenges, innovative solutions, and opportunities they face in their work in the field of trade and logistics. The aim of this paper is to conduct a comparative analysis and ranking of the LPI of the countries in the Western Balkans (Bosnia and Herzegovina, North Macedonia, Albania, Serbia and Montenegro), calculated by the World Bank for 2018, using an integrated Criteria Importance Through Intercriteria Correlation (CRITIC)-Measurement Alternatives and Ranking according to Compromise Solution (MARCOS) model and thus show the real picture of the logistics environment. In order to determine the performance of countries and show the overall logistics performance, six key dimensions are used: customs, infrastructure, international transport, logistics capability, tracking and tracing of goods and shipment delivery within scheduled or expected times. Using the CRITIC method, the weight values of the previously mentioned six criteria were calculated, whereby the criterion related to shipment delivery within scheduled times was singled out as the most significant criterion. Then, by applying the MARCOS method, the countries of the Western Balkans were ranked on the basis of the six defined criteria. Based on the results obtained, the best-ranked country is Serbia. The analysis of the sensitivity of the results to changes in the significance of the criteria does not show significant changes in the ranking.

Background: SARS-CoV-2 is a coronavirus that causes a respiratory disease, COVID-19. For COVID-19 testing, real-time PCR is considered gold standard and therefore many commercial SARS-Cov-2 detection kits are available. Objective: The aim of the study is to determine diagnostic values of 10 different commercially available SARS-CoV-2 detection kits, based on their Ct value. Methods: For this study thirty clinical nasopharyngeal samples were collected in ALEA Genetic Center. Twenty four of them were positive, while six were negative and used as a negative control. Positive samples were selected based on the day when first symptoms appeared. RNA was extracted using the same extraction method for all samples. For amplification and comparison of detection kits, the same RT- PCR instrument was used. Results: Accuracy, sensitivity, specificity and Cohen’s kappa coefficient were estimated to evaluate diagnostic values of the tested kits. This study showed that all kits showed 100% specificity. Accuracy, sensitivity and kappa coefficient varied among examined assays. Based on clinical features, LabGunTM COVID-19 Assay by LabGenomics proved to be the most sensitive, the most accurate and most specific. Therefore this assay was used as a reference kit. Conclusion: If things from practice are taken into account, accuracy and reliability of the tested commercial kits can vary compared to those obtained in this study where results were based on ideal functioning of the kits. When choosing the convenient commercial SARS-CoV-2 detection kit using RT-PCR method, many parameters need to be considered.

Aim To analyze an additional set of Y-chromosome genetic markers to acquire a more detailed insight into the diversity of the Croatian population. Methods A total of 518 Yfiler Plus profiles were genotyped. Allele frequencies, haplotype frequencies, and haplotype diversity were calculated by using the STRAF software v. 2.0.4. Genetic distances were quantified by Rst with AMOVA online tool from the YHRD. The evolutionary history was inferred with the neighbor-joining method of phylogenetic tree construction in the MEGAX software. Whit Athey's Haplogroup Predictor v. 5 was used for additional comparison with regional and other European populations. Results A total of 507 haplotypes were used for genetic STR analysis. An interpopulation study on 17 Y-STR markers showed the lowest genetic diversity between the Croatian and Bosnian-Herzegovinian populations and the highest between the Croatian and Irish populations. Additional interpopulation comparison with the original 27 Y-STR markers (for the population with available data) was also performed. A total of 518 haplotypes were used in the determination of haplogroup diversity. Haplogroup I with its sublineage I2a expressed the highest prevalence. The second most prevalent haplogroup was R, with its major sublineage R1a, except for the subpopulation of Hvar, where E1b1b was the second most prevalent haplogroup. Rare haplogroups also confirmed in this study were L, T, and Q. G1 was detected for the first time in the Croatian population. Conclusion We obtained a new insight into the differences between examined subpopulations of Croatia and their possible (dis)similarities with neighboring and distant populations.

Background: Human papillomavirus is a sexually transmitted infection and it is estimated that 75% of all women have been exposed to HPV infection in a certain period of life. High-risk types of HPV are considered to be one of the major causes of cervical cancer and its precursor intraepithelial neoplasia. Objective: The aim of this study was to investigate the degree of HPV infections and to provide more data on HPV genotype distribution among women in Bosnia and Herzegovina (B&H). Methods: Number of 375 samples were collected from different polyclinics in Sarajevo and were analyzed by Alea Genetic Center using Genomed f-HPV typing™ multiplex Fluorescent PCR kit for human papillomavirus genotyping. DNA required for this method is extracted from cervical swabs and amplified using a multiplex PCR reaction containing a set of 16 fluorescently labeled primers that recognize 16 HPV types. 14 HPV types are classified as high-risk (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68) and two are low-risk (6 and 11) HPV types. Results: Results showed that in the years 2018, 2019, and 2021, HPV type 16 is predominant causing the high-risk factor for CIN1, CIN2, CIN3, and cervical cancer development. HPV 18 infection rates decreased during the last four years of study. HPV 6 infection rates increased during that period of time. Conclusion: HPV 16 and HPV 18 are almost completely preventable by vaccination implying that the number of diagnosed cervical cancers in B&H could be much lower in the next decades if the HPV vaccination routine immunization program starts soon.

Background The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes a respiratory illness named coronavirus disease 2019 (COVID-19), which is one of the main global health problems since 2019. Glycans attached to the Fc portion of immunoglobulin G (IgG) are important modulators of IgG effector functions. Fc region binds to different receptors on the surface of various immune cells, dictating the type of immune response. Here, we performed a large longitudinal study to determine whether the severity and duration of COVID-19 are associated with altered IgG glycosylation. Methods Using ultra-high-performance liquid chromatography analysis of released glycans, we analysed the composition of the total IgG N-glycome longitudinally during COVID-19 from four independent cohorts. We analysed 77 severe COVID-19 cases from the HR1 cohort (74% males, median age 72, age IQR 25-80); 31 severe cases in the HR2 cohort (77% males, median age 64, age IQR 41-86), 18 mild COVID-19 cases from the UK cohort (17% males, median age 50, age IQR 26-71) and 28 mild cases from the BiH cohort (71% males, median age 60, age IQR 12-78). Findings Multiple statistically significant changes in IgG glycome composition were observed during severe COVID-19. The most statistically significant changes included increased agalactosylation of IgG (meta-analysis 95% CI [0.03, 0.07], adjusted meta-analysis P= <0.0001), which regulates proinflammatory actions of IgG via complement system activation and indirectly as a lack of sialylation and decreased presence of bisecting N-acetylglucosamine on IgG (meta-analysis 95% CI [-0.11, -0.08], adjusted meta-analysis P= <0.0001), which indirectly affects antibody-dependent cell-mediated cytotoxicity. On the contrary, no statistically significant changes in IgG glycome composition were observed in patients with mild COVID-19. Interpretation The IgG glycome in severe COVID-19 patients is statistically significantly altered in a way that it indicates decreased immunosuppressive action of circulating immunoglobulins. The magnitude of observed changes is associated with the severity of the disease, indicating that aberrant IgG glycome composition or changes in IgG glycosylation may be an important molecular mechanism in COVID-19.

Genus Silene (Caryophyllaceae) is very rich in secondary metabolites and has an antiviral, antimalarial, antitumor, antibacterial and antioxidant properties, but Balkan endemic Silene sendtneri (Sendtner's campion) is not analyzed from the aspect of phenolic composition and their biological activities. Evaluation of total phenolic contents (TPC) and total flavonoid contents (TFC), and antioxidant and antimicrobial activities of hydromethanolic extracts from inflorescences, stem, rhizome, and seeds of S. sendtneri, was done in this study for the first time. The TPC, TFC, and antioxidant activity (DPPH; 2,2-diphenyl-1-picrylhydrazyl) were determined by UV/VIS spectrophotometry. Antimicrobial activity was estimated against selected test microorganisms (Staphylococcus epidermididis, Staphylococcus aureus subsp. aureus, Salmonella abony, Escherichia coli, and Candida albicans) using a disc diffusion assay. The inflorescences had the highest (11.587 mg GAEg-1 DW) and rhizome the lowest TPC (2.017 mg GAEg-1 DW). The inflorescences extract exhibited the highest TFC (69.824 mg CEg-1 DW), while TFC was not detected in the rhizome extract. The stem’s extract had the highest antioxidant activity (IC50; 20.51%), while the rhizome had the lowest (61.89%). All extracts showed moderate antibacterial activity against Staphylococcus epidermididis and low activity against the three remaining tested organisms. Antifungal activity of inflorescence and rhizome extracts was moderate. Obtained results provide a basis for further investigations of various S. sendtneri extracts, which can be a potential natural antioxidant and antimicrobial agents

BACKGROUND Deep vein thrombosis (DVT) can be symptomatic or asymptomatic in patients with acute pulmonary embolism (PE). The prognostic value of the symptomatic DVT at the presentation regarding the prognosis of PE is unknown. METHODS Data were extracted from the REgional Pulmonary Embolism Registry (REPER) which enrolled 1604 hospitalized patients after multidetector computed tomography (MDCT) diagnosed symptomatic acute PE. According to the ESC risk model, patients were classified into four subgroups. Patients who had leg edema with or without pain, and patients with leg pain and DVT confirmed by compression ultrasound were considered to have symptomatic DVT. This study aims to compare all-cause hospital mortality between patients with symptomatic DVT and patients without symptoms or signs of DVT across the PE risk stratums. RESULTS All-cause mortality in patients with symptomatic DVT compared to those who had no signs or symptoms of DVT were 2/196 (1.0%) vs 11/316 (3.5%), p=0.145, 4/129 (3.1%) vs 17/228 (7.5%), p=0.106, 14/196 (7.1%) vs 54/290 (18.6%), p<0.001 and 16/55 (29.1%) vs 51/139 (36.7%), p=0.402 in patients with low, intermediate-low, intermediate-high and high-risk PE, respectively. In multivariate analysis symptomatic DVT was associated with decreased inhospital mortality only in patients with intermediate-high PE (OR 0.320, 95%CI 0.164-0.627; p=0.001). Intermediate-high risk PE patients with symptomatic DVT who were treated with thrombolysis had significantly lower hospital mortality than patients without signs or symptoms of DVT (2.2% vs. 11.4%, p=0.003). CONCLUSIONS Intermediate-high risk PE patients with symptomatic DVT at presentation may benefit from thrombolysis and have lower hospital all-cause mortality in such circumstances.

The past decade within Bosnia and Herzegovina and thus in the Sarajevo Canton has shown that tourism has become a significant segment of the economy with a pronounced constant positive growth. He is one of the most important trump cards in economic development and positive recognition of the Sarajevo Canton and thus the state of Bosnia and Herzegovina. The paper analyzes the current state of sports and recreational tourism in Sarajevo Canton in the period from 2011 to 2021 and its possibilities through the sports and tourism offer. The research covered the administrative borders of Sarajevo Canton, which consists of 9 municipalities: Centar, Hadžići, Ilidža, Ilijaš, Novi Grad, Novo Sarajevo, Stari Grad, Trnovo and Vogošća. The paper analyzes the number of registered business entities (tourist units), the number of tourist arrivals (countries from which tourists come and by months of the year), the number of overnight stays, tourist arrivals individually or organized, the analysis of sports facilities and infrastructure for sports and tourism offer (mountaineering, sport climbing, athletic stadiums, swimming pools, bike and mountain bike trails, sports halls, golf courses, mountain walking trails, racetracks (equestrian sports), skating rinks, football stadiums and football fields, ski lifts, ski lifts, snowboard, point and toboggan runs, cross-country skiing, tennis courts). For the purposes of this research, a combination of: primary field research related to the state of sports facilities and sports infrastructure in the Sarajevo Canton as well as a secondary method of data collection through available official data, databases and reports of relevant public, private institutions, media, sports associations. By analyzing the situation and the results we have obtained, we can determine the direction for the development and expansion of services in terms of sports and recreational tourism in Sarajevo Canton. This does not require large investments, especially in the rural parts of Sarajevo Canton, which has all the benefits for further development of sports and recreational forms of offer in the direction of hiking, mountaineering, cycling, running, alpine, touring and Nordic skiing. Sarajevo Canton with its sports and competitive heritage as well as the existing specific sports infrastructure and facilities provide a great opportunity for tourism development and positive recognition of the Canton and the city of Sarajevo. Keywords: Seasonality, sports facilities, sports infrastructure, sports and recreational services and sports programs.

Background: The COVID-19 pandemic has become a major cause of stress and anxiety worldwide. It has generated stress among people from all sections of society, especially to workers who have been assigned to cater to healthcare service or those constrained to secure daily essential items. Yoga practice is actively sought to achieve reduced anxiety and stress so that improved sleep may positively impact immunity. Objective: The aim of this cross-sectional study was to determine whether those who practice Yoga during the COVID-19 pandemic have lower levels of stress, anxiety, and depression than those who do not. Methods: The sample consists of 51 females who have been attending Yoga sessions for many years and who continued this practice during the COVID-19 pandemic twice a week. The control group consisted of 50 non-Yoga respondents. The survey was conducted during April 2021. The Revised Event Impact Scale (IES-R) (4) and the Brief Symptom Inventory (BSI) (Derogatis, 1993) were used to assess stress. Student T-test was used to check the statistical significance of differences. Results: In our research yoga practitioners show a statistically significantly lower average severity of stress symptoms compared to those who do not practice yoga on 5 of the 6 stress indicators shown. The only statistically significant difference was not obtained on the measure of total number of symptoms (PST). Conclusion: The results suggest that yoga practice during COVID-19 pandemic is associated with lower levels of stress, anxiety and depression.

Background: The Brixia scoring system interpreted chest X-ray changes, serves as an indicator of the extent of changes in the lung parenchyma Objective: To indicate the effect of D-dimer and C-reactive protein (CRP) on Brixia score in patients with positive polymerase chain reaction (PCR) test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods: The research had prospective, descriptive and analytical character, and included patients (n=104) with Coronavirus disease 2019 (COVID-19) diagnosis. Chest X-ray, as well as calculation of Brixia score was done on admission, in the first week of hospitalization, on discharge, and 10 days after discharge (the patient was considered a post-COVID patient. Maximum CRP and D-dimer values were taken into account, along with data about dependence of mechanical ventilation and oxygen therapy. Results: Initial Brixia score was significantly associated with the values of CRP (r = .23, p <.05). Higher level of CRP affected the higher result on the Brixia score after the initial X-ray. High CRP and D-dimer were significantly associated with oxygen use in patients, while high D-dimer was also statistically significantly associated with comorbidity. The mean value of Brixia score (during four time points) was significantly related to the values of CRP, D-dimer, the use of mechanical ventilation and oxygen therapy, but also with the existence of comorbidities. The largest statistically significant positive correlation of Brixia scora is with the values of D-dimer (r = .45, p <.000), but also with the values of CRP (r = .36, p <.000). Conclusion: Values of CRP have an impact on Brixia score. Investigation of clinical characteristics and outcomes of severe clinical presentation of COVID-19 along with CXR scoring system will contribute to early prediction, accurate diagnosis and treatment as well as to improve the prognosis of patients with severe illness.

Introduction Clozapine is a drug that can cause several side effects. Among the less commonly described is a drug-induced lung disease. Due to its non-specific clinical presentation, it represents a diagnostic challenge. The diagnosis is made based on: 1. Association of exposure to the agent and development of symptoms, 2. Pulmonary infiltration, 3. Exclusion of other causes, 4. Withdrawal of symptoms when the agent is excluded from therapy. To date, there have been only a few descriptions of this condition. Objectives Case report of rare side effect of clozapine. Methods Case report Results Case report: male patient (37) with schizophrenia, was hospitalized after a brutal suicide attempt. The PCR test for COVID-19 that was routinely performed on admission was negative. After the introduction of clozapine into therapy, the patient became febrile. There was a drop in oxygen saturation, a Lung CT scan showed inflammatory changes („ground-glass opacities“), and COVID-19 pneumonia was suspected. Due to the worsening of the mental state, the dose of clozapine was increased. The physical condition further deteriorated: febrile, sO2 declining. After repeated PCR tests for COVID-19 (all negative), interstitial pneumonia caused by clozapine was suspected, and clozapine was excluded from therapy. The physical condition started to improve. Quetiapine was introduced, and occasional episodes of agitation were relieved with intramuscular diazepam. In the following days, the patient’s mental state improved and he was discharged. Conclusions Despite its superiority over other antipsychotics, clozapine was with good rationale ranked third in treatment guidelines for schizophrenia. Disclosure No significant relationships.

Women’s rights have increasingly become an international concern and various in-ternational conventions on women’s rights came into being in the last decades. Bosnia-Herzegovina has signed and ratified all important international conven-tions relating to women’s rights, whereas the numerous women's civil society organ-izations continue to advocate for the proper implementation of conventions while helping women to claim their rights guaranteed in these conventions and locally enacted laws on gender equality. This article, based on interviews conducted be-tween August 2020 and June 2021 with members of women's civil society organiza-tions in Bosnia-Herzegovina, takes a closer look at the process of norm diffusion. In particular, this article aims to contribute to the understanding of the processes of norm implementation and the related challenges from the perspective of women’s civil society organizations in the specific context of Bosnia-Herzegovina.

Introduction: Neck pain (NP) may have a local mechanical (non-specific) origin caused by dysfunction of the joint, muscle, and ligament structures in the neck or by a discogenic etiology. Most people (50–60%) suffer from NP at some point in their lives. They are more common in highly developed countries and in urban areas. The aim of this study is to determine the prevalence of NP and its impact on daily living activities in the student population. Methods: The study included students of the University of Sarajevo - Faculty of Health Studies in the period from May 2021 to June 2021. The sample of respondents was formed by the method of random selection and included respondents of both sexes, aged 19–28 years. The study was conducted as a transversal cross-sectional study at a specific time point on the frequency of NP and the ability to perform activities of daily living in the student population. Results: Out of the total number of 255 respondents, 77 (30.2%) reported that they have NP while 178 (69.8%) respondents reported that they do not feel NP and it was found that there was no statistically significant difference between the age groups of the subjects with and without NP. The study concluded that a higher percentage of respondents with NP did not engage in leisure activities and that respondents with NP had lower mobility in daily life, sleep disturbance, and poorer ability to perform activities of daily living due to NP. Conclusion: The study conducted revealed that a significant percentage of the student population with NP has a lower ability to perform activities of daily living. Considering the above facts and the current transformation of the educational model, in which static postures dominate, it is necessary to design and implement programs for targeted physical activity and prevention of long-term inactivity that leads to painful musculoskeletal syndromes.
