Poultry meat production is one of the most dynamic sectors in agriculture, recording the quickest growth in the food industry, while egg production has shown strong growth in the last twenty years. Combined with meat production, it is achieving the highest growth when it comes to meeting protein needs for the global population. In economic terms, coccidiosis is one of the most significant poultry diseases. Effective application of coccidiostats in poultry feed has been playing a key role in development of commercial poultry production for more than 50 years. The aim of this research was to estimate occurrence and residue concentrations of coccidiostats in table eggs, poultry liver and meat, available on the market in Bosnia and Herzegovina (B&H). Residues of lasalocid were found in table eggs, while residues of nicarbazin, maduramicin and diclazuril were detected in broiler meat and liver.

This research aimed to study the influence of differences in the composition and storage length of mechanically deboned poultry meat (MDPM) on the sensory properties of frankfurters. Three variants of frankfurters were produced from three respective alternatives of MDPM that differed solely in proportions of meat from broiler backs and necks. Similarly, a commercially available and freshly produced MDPM of unknown composition was used as the control. All the four variants of MDPM were stored at -18 °C for 1, 45 and 90 days. Sensory profiling of the frankfurters was performed by 8 panellists using a quantitative-descriptive analysis (QDA). Two-factorial ANOVA and principal component analysis (PCA) of the sensory evaluation results revealed significant (p < 0.05) effects of the storage time of the MDPM variants on sensory characteristics of the frankfurters, regardless of their composition.

The COST Action Gene Regulation Ensemble Effort for the Knowledge Commons (GREEKC, CA15205, www.greekc.org) organized nine workshops in a four-year period, starting September 2016. The workshops brought together a wide range of experts from all over the world working on various parts of the knowledge cycle that is central to understanding gene regulatory mechanisms. The discussions between ontologists, curators, text miners, biologists, bioinformaticians, philosophers and computational scientists spawned a host of activities aimed to update and standardise existing knowledge management workflows, encourage new experimental approaches and thoroughly involve end-users in the process to design the Gene Regulation Knowledge Commons (GRKC). The GREEKC consortium describes its main achievements, contextualised in a state-of-the-art of current tools and resources that today represent the GRKC.

TOPIC: Education, Research, and Quality Improvement TYPE: Original Investigations PURPOSE: The need for swift international collaboration alongside rapidly deployable remote medical knowledge transition and implementation programs has been highlighted during the ongoing COVID-19 pandemic. Virtual programs have emerged as cost-effective alternatives to in-person education to spread best practices to resource-limited locations and garner purposeful learner engagement. Understanding local practice needs is paramount to the development of an effective quality improvement initiative. This study aimed to gain insight into the interests, clinical challenges, and attitudes of a group of interprofessional critical care providers from Bosnia and Herzegovina in preparation for a longitudinal remote education and quality improvement program. METHODS: A novel learning needs assessment tool was implemented in a cohort of critical care professionals from four hospitals in Bosnia and Herzegovina. A sequential explanatory design was employed, and a mixed-method assessment was conducted in three phases. 1) Utilizing the Delphi method, twenty statements containing common critical care entrustable professional activities (EPAs) were developed by a board of intensivists and medical education specialists. 2) Local learners used Q Sort methodology to rank-order EPAs based on self-perceived learning priorities, with subsequent by-person factor analysis. 3) Learners were invited for focus-group interviews to gather details of the rationale behind their rankings. RESULTS: Forty nine out of 105 participants completed the rank-order survey (response rate 47%). Factor analysis categorized the participants into two main groups based on the typology of their opinions, 22 participants into factor 1 and 9 participants into factor 2. The highest-ranked EPAs amongst the two factors were “evaluation and management of the patients with shock, stabilization, and resuscitation of critically ill patients” and “evaluation and management of ARDS,” respectively. Statements regarding common ICU complications and procedures were regarded as neutral. The lowest rank amongst factor 1 was “patient-centered care, communication skills, and interprofessional collaboration.” Participants in factor 2 ranked “preoperative evaluation and management” and “common hematologic and oncologic complications” the lowest. The rationale behind rank orders focused on the current patient population and perceived EPA importance to critical care practice. Participants in factor 1 displayed pessimistic attitudes toward patient-centered care and interprofessional collaboration due to cultural and healthcare system constraints. Interviewees in both factors described local challenges and expressed a need for change. CONCLUSIONS: We conducted a remote needs assessment in an international, interprofessional group of critical care providers. In addition to building trust with learners, the acquired knowledge of cultural differences, needs, and barriers to implementation will guide an ongoing remote education and quality improvement initiative. CLINICAL IMPLICATIONS: This investigation will shape a critical care best practices quality improvement initiative and remote education program in a country with limited resources.

Simple Summary CD8+ T cells are prominent decidual cells in the third trimester of healthy human pregnancy. They have a cytotoxic capacity which may control invasion of extravillous trophoblast and therefore affect placentation and play the role in development of preeclampsia. In this study, we examined the expression of CD8+ T cells in decidual tissue and peripheral blood of women with severe and mild preeclampsia in comparison to gestational age-matched healthy pregnancies. Additionally, the expression of cytotoxic proteins in CD8+ T cells was examined in order to specify their subpopulations. Abstract In our study, we aimed to establish expression of cytotoxic CD8+ T cells in the decidua basalis and the maternal peripheral blood (mPBL) of severe and mild preeclampsia (PE) and compare to healthy pregnancies. Decidual tissue and mPBL of 10 women with mild PE, 10 women with severe PE, and 20 age-matched healthy pregnancy controls were analyzed by double immunofluorescence and qPCR, respectively. By double immunofluorescence staining, we found a decreased total number of cells/mm2 in decidua basalis of granulysin (GNLY)+ (p ˂ 0.0001), granzyme B (GzB)+(p ˂ 0.0001), GzB+CD8+(p ˂ 0.0001), perforin (PRF1)+ (p ˂ 0.0001), and PRF1+CD8+ (p ˂ 0.01) in the severe PE compared to control group. Additionally, we noticed the trend of lower mRNA expression for GNLY, granzyme A (GZMA), GzB, and PRF1 in CD8+ T cells of mPBL in mild and severe PE, with the latter marker statistically decreased in severe PE (p ˂ 0.001). Forkhead box P3 (FOXP3) mRNA in CD8+ T cells mPBL was increased in mild PE (p ˂ 0.001) compared to controls. In conclusion, severe PE is characterized by altered expression of cytotoxic CD8+ T cells in decidua and mPBL, suggesting their role in pathophysiology of PE and fetal-maternal immune tolerance.

The International Organisation for Animal Health (OIE), from the onset of COVID-19 pandemic, promoted One Health in global and national responses. The OIE accentuated the role of the veterinary profession due to testing capacity of animal health laboratories and expertise. Veterinary Faculty Sarajevo through its Veterinary Institute participates in the national veterinary service with diagnostic and advisory roles. It has proactively enhanced the scope and quality of laboratories, including strengthening the interdisciplinarity and internationality. Development achieved through earlier pandemic threats resulted in having laboratory and technical facilities for molecular SARS-CoV-2 detection in the wake of the unveiling COVID-19 pandemic (early 2020). From confirmation of the first COVID-19 cases in Bosnia and Herzegovina (BiH), our staff participated in crisis response teams and, so far, held over sixty media addresses promoting public awareness and science based information. Our laboratories were included in the official detection system and were the first to sequence SARS-CoV-2, then to establish the Alpha COVID-19 variant in BiH human samples and to substantiate one-way virus transmission from humans to pets. The aim of this paper is to describe our activities as a participant in the response to the COVID-19 pandemic, alongside faced challenges and gained experiences.

Many wild animal populations are considered endangered due to anthropogenic activities. Wildlife and nature habitat preservation requires holistic and science based approaches supported by adequate regulations. One of the means for wildlife preservation is undoubtedly heath monitoring and investigation of infectious diseases of the wild animal populations, particularly if spillover effects are considered. Even though the theoretical background is well researched, implementation of disease prevention and control measures in wildlife populations entails more challenges than in domestic animal populations. Immediate signs of health disorders in wildlife often become evident when the infectious agent is well established in an area. Additionally, due to unrestricted and often long-range movement of wildlife, diseases are easily spread across borders. Brown bears, indigenous in Europe, are classified by EU regulations as endangered, almost extinct and rare. The wild bear population in Bosnia and Herzegovina shares a genetic lineage with bear populations of neighbouring Croatia, Serbia and Montenegro and is one of the few remaining fragments of bear populations in Europe. The aim of this paper is to describe implemented activities for health and telemetric monitoring of wild bears in the Nature Park Skakavac, Canton Sarajevo, Bosnia and Herzegovina.

Abstract Age estimation is a key component in forensic analysis, be it in legal proceedings or archeological research. Current methods in forensic odontology are based on manual measurements of a wide array of morphometric parameters, typically from dental x-ray images, and occasionally from material remains. While those parameters follow a set progression during human development, thereby allowing current methods to precisely estimate the age of juveniles, estimation for adults and seniors proves to be more difficult. In this study, we explore the applicability of deep learning to the problem of chronological age estimation. We determine the best convolutional neural network model derived from state-of-the-art architectures, we determine the best performing model parameters using pretrained general-purpose vision model parameters as the starting point, and we perform ablation experiments to highlight which anatomical regions of the dental system contribute the most to the estimation. The proposed approach attains the lowest estimation error in literature for adult and senior subjects, which we verify on one of the largest datasets of panoramic dental x-ray images in literature. The dataset consists of 4035 panoramic dental x-ray images of male and female subjects with ages between 19 and 90 years. This study also evaluates the feasibility of the proposed model for age estimations of individual teeth, achieving an estimation error competitive with current methods while being fully automated. The estimation error is verified on our dataset of 76416 individual tooth images, which is the largest dataset to date in forensic odontology literature. Unlike current methods, dental alterations, decay, illnesses, or missing teeth do not pose a problem to the proposed model. With a median estimation error of 2.95 years for panoramic dental x-ray images and 4.68 years for individual teeth, and by deriving the model from state-of-the-art architectures, verifying those results on the largest dataset in forensic odontology literature and demonstrating the importance of different anatomical regions of the dental system for estimation, this study sets the baseline for future research of automated chronological age estimation in forensic odontology.

BACKGROUND In this cross-sectional, international study, we aimed to analyze vector-borne and zoonotic infections (VBZI), which are significant global threats. METHOD VBZIs' data between May 20-28, 2018 was collected. The 24 Participatingcountries were classified as lower-middle, upper-middle, and high-income. RESULTS 382 patients were included. 175(45.8%) were hospitalized, most commonly in Croatia, Egypt, and Romania(P = 0.001). There was a significant difference between distributions of VBZIs according to geographical regions(P < 0.001). Amebiasis, Ancylostomiasis, Blastocystosis, Cryptosporidiosis, Giardiasis, Toxoplasmosis were significantly more common in the Middle-East while Bartonellosis, Borreliosis, Cat Scratch Disease, Hantavirus syndrome, Rickettsiosis, Campylobacteriosis, Salmonellosis in Central/East/South-East Europe; Brucellosis and Echinococcosis in Central/West Asia; Campylobacteriosis, Chikungunya, Tick-borne encephalitis, Visceral Leishmaniasis, Salmonellosis, Toxoplasmosis in the North-Mediterranean; CCHF, Cutaneous Leishmaniasis, Dengue, Malaria, Taeniasis, Salmonellosis in Indian Subcontinent; Lassa Fever in West Africa. There were significant regional differences for viral hemorrhagic fevers(P < 0.001) and tick-borne infections(P < 0.001), and according to economic status for VBZIs(P < 0.001). The prevalences of VBZIs were significantly higher in lower-middle income countries(P = 0.001). The most similar regions were the Indian Subcontinent and the Middle-East, the Indian Subcontinent and the North-Mediterranean, and the Middle-East and North-Mediterranean regions. CONCLUSIONS Regional and socioeconomic heterogeneity still exists for VBZIs. Control and eradication of VBZIs require evidence-based surveillance data, and multidisciplinary efforts.

Scholastic factors (academic achievement) are hypothesized to be important determinants of health-related behaviors in adolescents, but there is a lack of knowledge on their influence on physical activity levels (PAL), especially considering the COVID-19 pandemic and the imposed lockdown. This study aimed to investigate the associations between scholastic factors and PAL before and during the pandemic lockdown. The participants were adolescents form Bosnia and Herzegovina (n = 525, 46% females), who were observed prospectively at the baseline (before the pandemic lockdown) and during the lockdown in 2020 (follow-up). The scholastic factors (grade point average, behavioral grade, school absences, unexcused absences) were evidenced at the baseline (predictors). The outcome (PAL) was evaluated using the Physical Activity Questionnaire for Adolescents at the baseline and the follow-up. Gender, age, parental/familial conflict, and sport participation were observed as confounders. No significant influence of the predictors on PAL were evidenced at the baseline or at the follow-up. The scholastic variables were significantly associated with the changes of PAL which occurred due to pandemic lockdown, with a lower risk for negative changes in PAL among adolescents who were better in school (OR = 0.56, 95%CI: 0.34–0.81, and OR = 0.66, 95%CI: 0.34–0.97, for the grade point average and behavioral grade, respectively). Students who do well in school are probably more aware of the health benefits of proper PAL, and therefore are devoted to the maintenance of their PAL even during the home-confinement of lockdown. Public health authorities should focus more on helping adolescents to understand the importance and benefits of proper PAL throughout the school system.
