    مستخلص: Objective: Despite multiple studies from high-income countries, reports from low- and middle-income countries on the impact of COVID-19 on head and neck cancer care remain sparse. This study aimed to assess the effects of the COVID-19 pandemic on head and neck cancer patients at a tertiary reference centre in Bosnia and Herzegovina.
    Methods: We included 228 patients with malignant head and neck tumours evaluated and treated between January 1, 2019, and December 31, 2021. Patient demographics, histological characteristics, and treatment modalities were retrospectively obtained and compared between the pre-pandemic period (pre-COVID-19 group) and the period after the implementation of COVID-19 restrictive measures (COVID-19 group).
    Results: Patients were significantly older during the COVID-19 pandemic. In particular, 63 patients (44.7%) were under 65 and 78 (55.3%) were 65 or older, while in the pre-COVID-19 period, 53 patients (60.9%) were under 65 and 34 (39.1%) were 65 or older (p = 0.017). The pre-COVID-19 and COVID-19 groups did not significantly differ regarding other patient- and tumour characteristics, or primary treatment modalities.
    Conclusions: During the COVID-19 pandemic, significantly fewer patients were under 65 at the time of initial work-up, potentially reflecting the more enhanced disease-related anxiety of the younger population. Future studies are warranted to address this population's specific educational and psychological needs to ensure appropriate cancer care.

    مستخلص: Mpox virus (MPXV) infection is difficult to distinguish from other (non-)infectious diseases. The etiology of rash can be differentiated by real-time polymerase chain reaction (rtPCR) on different types of samples. The study aims to provide experience with emerging MPXV diagnostics in a tertiary-level laboratory in Bosnia and Herzegovina. From July-December 2022, a total of 18 mpox suspected persons were tested. MPXV infection was confirmed by rtPCR in 10/18 (55.56 %) persons. The number of cases reached a peak in October 2022. The lowest median Crossing point (Cp) (x̄ = 29.76) was obtained from a swab of skin lesions in a viral transport medium (VTM). Evaluating the Cp values for the 7/9 mpox cases from whom paired swab samples from different anatomic sites were collected, higher positivity of skin lesion swabs in VTM was observed. In conclusion, our data highlighted the confirmatory role of rtPCR in the diagnosis of MPXV in skin lesion samples.

    مستخلص: Over the past 30 years, forensic experts from Croatia and Bosnia and Herzegovina have embraced advanced technologies and innovations to enable great efficacy and proficiency in the identification of war victims. The wartime events in the countries of former Yugoslavia greatly influenced the application of the selected DNA analyses as routine tools for the identification of skeletal remains, especially those from mass graves. Initially, the work was challenging because of the magnitude of the events, technical aspects, and political aspects. Collaboration with reputable foreign forensic experts helped tremendously in the efforts to start applying DNA analysis routinely and with increasing success. In this article, we reviewed the most significant achievements related to the application of DNA analysis in identifying skeletal remains in situations where standard identification methods were insufficient.

    مستخلص: Aim: To assess the association of single nucleotide polymorphisms (SNPs) in the ACE2 and TMPRSS2 genes with COVID-19 severity and key biomarkers.
    Methods: The study involved 750 COVID-19 patients from Bosnia and Herzegovina, divided into three groups: mild, moderate, and severe cases. Genetic variations within the ACE2 (rs2285666) and TMPRSS2 (rs2070788) genes were examined with real-time polymerase chain reaction. Biochemical markers were determined with standard procedures.
    Results: There was a significant difference in the rs2070788 genotype distribution between patients with mild and moderate symptoms, but not between other groups. For the rs2285666 polymorphism, no significant difference in genotype distribution was found. In patients with mild symptoms, carriers of the GG genotype of rs2070788 had significantly higher total bilirubin levels than carriers of the AA genotype. Similarly, carriers of the TT genotype of rs2285666 had significantly higher activated partial thromboplastin time and international normalized ratio, and lower lactate dehydrogenase levels compared with the CC genotype. Among patients with severe symptoms, carriers of the GG genotype showed significantly higher potassium levels than carriers of the AA genotype, while carriers of the TT genotype showed significantly higher erythrocyte count as well as hemoglobin and hematocrit levels compared with the CC genotype.
    Conclusion: This study highlights the role of genetic factors, particularly SNPs in the ACE2 and TMPRSS2 genes, in determining COVID-19 severity, aiding patient risk assessment and prognosis.

    مستخلص: Objectives: Work-family conflict is a growing problem worldwide, because of changing work-family demographic trends and the spread of technology. Empathy, as the ability to understand and share the feelings of other people, is the essential component of emotional intelligence that plays a crucial role in healthcare settings. This study aimed to assess the level of emotional empathy and investigate its relationship with work-family role conflicts among dental medicine doctors.  Materials and methods: In this study participated 589 doctors of dental medicine from Croatia, Serbia, Bosnia and Herzegovina. The questionnaire included general and demographic data, the Emotional Empathy Scale questionnaire and the Work and Family Role Conflict Assessment Scale questionnaire.  Results: The research results indicate no significant association between empathy and conflict between work and family roles (R = 0.032, p = 0.435). Women have achieved significantly higher scores in Emotional Empathy Scale (p ≤ 0.001), while there was no difference in Work and Family Role Conflict Assessment Scale according to gender (p = 0.194). A difference in emotional empathy was observed depending on where the respondents were employed (p = 0.045) and depending on the specialisation of the dental medicine (p = 0.021).  Conclusion: Female doctors of dental medicine demonstrated higher emotional empathy while the work-family role conflict is experienced equally by both genders.

    مستخلص: Background: Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia have committed to becoming European Union (EU) member states. This, among others, implies that candidate/potential candidate states adopt legally authorized EU policies, including health. The study aims to identify the main country-specific health policy areas critical to the EU accession health policy dimension and present the change in associated selected health indicators from 2000 to 2019.
    Methods: The study draws on published reports and analyses of official statistics over time and cross-country. Health care policy adherence to the European Commission's recommended country-specific health actions was classified into five health policy areas: financing, payment, organization, regulation and persuasion. Key health policy areas for Western Balkan countries (WBCs) were identified. Health progress or lack thereof in catching up to the EU15 population health, health expenditure and the number of health professionals are measured.
    Results: The European Commission prioritized financing and regulation for all WBCs in the five policy areas. Nine of the 18 analyzed selected health indicators showed divergence, and the other nine converged towards the EU15 averages. WBCs continue to face diverse public health challenges in improving life expectancy at birth, death rates caused by circulatory system diseases, malignant neoplasms, traffic accidents, psychoactive substance use, tuberculosis incidence, tobacco smoking prevalence and public-sector health expenditure.
    Conclusions: By 2019, there is limited evidence of WBCs catching up to the average EU15 health levels and health care policies. Closer attention towards EU health and health care policies would be favourable.

    مستخلص: Background: Cigarette use is one of the major risk factors for non-communicable diseases in Bosnia and Herzegovina, with 41.1% of adults being current smokers in 2019 and almost half of current smokers using more than 20 cigarettes per day.
    Methods: This study applies the prevalence-based, cost-of-illness approach to estimate the annual economic cost of smoking in Bosnia and Herzegovina in 2019.
    Results: The study estimates that cigarette use by adults in Bosnia and Herzegovina caused between 24.4% and 42.8% of all deaths in 2019 and a total economic cost of between €367.5 and €635.1 million (2.0%-3.5% of gross domestic product). The direct costs represent the largest share of the total cost (between 1.0% and 1.7% of gross domestic product).
    Conclusion: Cigarette use imposes a significant health and economic burden in the society of Bosnia and Herzegovina. Various tobacco control measures can be implemented to prevent and reduce tobacco consumption and the negative health consequences of tobacco use. Numerous studies have shown taxes on tobacco products are very effective in reducing tobacco use, especially among certain demographic groups, such as youth and low-income individuals. Smoke-free laws have also shown benefits. Other policy measures that can be implemented include restrictions to advertising, limitations on who can purchase tobacco products, how and where they can be purchased, etc. In addition, governments could also implement various education programmes on the negative health consequences of smoking. The results of this study provide information that calls for prompt and strengthened implementation of tobacco control measures to reduce cigarette consumption in the country and improve the health outcomes and productivity of its inhabitants.

    مستخلص: Introduction: Due to treatment of end-stage-renal-disease (ESRD), continuous peritoneal dialysis (CAPD) is used in 11% of cases and is associated with several PD-associated infections.
    Methods: Clinical data on 71 patients with CAPD were evaluated in addition to exit site infections and episodes of acute peritonitis (AP).
    Results: There were 39 men and 32 women. Average age was 61 years when we began CAPD and average time spent on CAPD program was 3.35 years. Illness that dominantly caused ESRD was diabetes (23 patients). Exit site infection was mostly caused by S epidermidis-MRSE and AP was most commonly caused by Staphylococcus sp. group. Most common cause of death was cardiovascular disease. At the end of this study, 9 patients were alive and still on CAPD, 10 were transplanted, 15 switched to HD and 36 died.
    Conclusion: Optimal prevention measures and treatment of infectious complications in CAPD is necessary for better treatment possibilities.

    مستخلص: Leptospirosis is a (re) emerging zoonosis that occurs worldwide. This study aimed to assess seroprevalence of leptospirosis and to identify the most common reactive serovars and risk factors for seropositivity in apparently healthy stray dogs of unknown vaccination status in the Sarajevo region of Bosnia and Herzegovina. Positive microscopic agglutination test titres (≥ 1:25) were detected in 3.87% (156/4028) of samples and most of the sera reacted against one serovar (85.9%). Dogs were most commonly reactive to Canicola (40.4%) and Hardjo (33.3%), followed by Pomona (15.4%) Tarassovi (14.7%), Icterohaemorrhagiae (8.3%), Grippotyphosa (5.8%), Bratislava (1.3%) and Saxkoebing (0.6%). Dogs older than one year had higher odds of seropositivity compared to younger dogs. The seropositivity was higher in spring and autumn than in summer. These results advocate for the need of a control strategy for this zoonosis in the country, which should include sero-surveillance, monitoring, and the inclusion of additional serovars in the testing.

    مستخلص: COVID-19 vaccine uptake in the Federation of Bosnia and Herzegovina (FBiH) accelerated in the second half of 2021, with greater vaccine availability. In this study, we estimated the vaccine effectiveness (VE) of complete primary series BBIBP-CorV vaccine against COVID-19 in patients aged 60 years and older, during the Delta-dominant period, using a test-negative case-control design. Surveillance sites were 11 primary health care centers (PHC) collecting patient data from October 1, 2021, to January 4, 2022, retrospectively according to a common protocol. In total, we included 1711 participants in the analysis: 933 cases and 778 controls. Of the 933 cases, 508 (54.4 %) had mild and 425 (45.6 %) had moderate to severe disease presentation. We observed no effectiveness against mild COVID-19. Overall vaccine effectiveness was 65.0 % (95 %CI: 40.1-79.5) against moderate to severe COVID-19. In time since vaccination analysis, VE was 78.7 % (95 % CI: 54.8-89.9) in patients who received their last dose < 90 days before onset; 66.0 % (95 % CI: -0.5-88.5) in those 90-119 days before onset; 42.1 % (95 % CI: -88.6-82.3) in those 120-149 days before onset and 45.0 % (95 % CI: -94.0-84.4) in those ≥ 150 days before onset. In our study, two doses of BBIBP-CorV provided considerable protection against moderate to severe COVID-19 in older adults, highest within 3 months after second dose, during the Delta-dominant period. Point estimates declined thereafter, suggesting a need for additional doses.
