Authors: Sargsjan Christina
Published: December 2024

In Frankreich sind seit September zwei Fälle sexualisierter Gewalt in den Fokus der Öffentlichkeit gerückt. Die erschütternden Geschichten von Gisèle Pelicot und die jüngsten Enthüllungen rund um den katholischen Priester Abbé Pierre, einer der bekanntesten und bis vor kurzem noch hoch angesehenen Persönlichkeiten des 20. und 21. Jahrhunderts in Frankreich, haben nicht nur nationale, sondern auch internationale Diskussionen ausgelöst. Sie offenbaren tiefgreifende Missstände im Umgang mit Missbrauchsopfern und werfen grundlegende Fragen zum Umgang der Gesellschaft mit sexualisierter Gewalt auf. „La hônte change le camp“, auf Deutsch, „die Scham wechselt die Seite“ ist das Leitmotiv in der Diskussion.

Published: December 2024

The present study was conducted to determine the occurrences and features of repeat breeding and postpartum anestrous in crossbred dairy cattle. A longitudinal prospective study was carried out on 371 pregnant dairy cows to determine the occurrences of repeat breeding and postpartum anestrus. Ultrasonographic examination was undertaken on repeat breeder and postpartum anestrus cows to identify the features of repeat breeding and postpartum anestrus in crossbred dairy cows. The incidence of postpartum anestrous and repeat breeding in crossbred dairy cattle was high at 40.9 and 38.2%, respectively. From cows or heifers recorded as repeat breeders, 59.2% of cows and heifers had regular estrous cycle and functional corpus luteum, while the remaining 40.8% of dairy cows had no regular estrous cycle and functional corpus luteum in ultrasonographic examination of utero-ovarian conditions. From the cows recorded as postpartum anestrus, 34.7% of cows were true anestrus, 54.7% of cows were subestrus, and the remaining 10.5% of cows were with cystic ovary. The present study indicated that 22.6% of total dairy cows examined under the present study could not conceive within 1 year of postpartum due to repeat breeding syndrome. Moreover, 40.8% of repeat breeder dairy cows were conceived after a repeated number of services within 1 year of postpartum.

The Evolving Menace: Emerging Escherichia Species and Their Implications for Animals and Public Health
Authors: Torkan Afagh , Askari Badouei Mahdi
Published: December 2024

While the bacterium Escherichia coli is a well-known member of the human gut microbiota, newer members of the genus Escherichia are increasingly being recognized as emerging public health threats. These species have been isolated from various animal hosts, including livestock, pets, and wildlife, as well as from human clinical samples. The genus Escherichia has been expanded as novel species such as E. fergusonii, E. albertii, E. marmotae, E. ruysiae, and E. whittamii have been added. Concerning reports have linked these Escherichia newcomers to a variety of severe illnesses, such as hemolytic uremic syndrome (HUS), diarrhea, and systemic infections in humans and animals. Their apparent ability to cause disease in a wide range of hosts raises worrying questions about their zoonotic potential and ability to cross species barriers. As these Escherichia species continue to be identified more frequently, further focus is needed to understand their epidemiology and public health implications to develop effective prevention and control strategies. Currently, the scientific community is actively working to stay ahead of these evolving Escherichia threats through improved detection, prevention, and control strategies to protect both animals and humans.
Riding the Permafrost Rooster: Avian Ecology and Bird Flu
Authors: C. Canavan Barbara
Published: December 2024

Beginning in 2005, Qinghai Lake on the Tibetan Plateau was the scene of the unprecedented appearance of avian influenza among migratory birds. These were significant events in the subsequent global spread of the virus to poultry (and occasionally humans) in many new countries on three continents. Events at Qinghai sparked energetic debates about the role of migratory birds in spreading influenza viruses among domestic and wild birds. In turn, this led to cross-disciplinary research that highlighted the interconnections of environment, wildlife, and human activities. Factors in the Qinghai case study (Qinghai) include the vast permafrost landscape of the Tibetan Plateau, the ecology of wild geese that migrate over the Himalayas, a high-altitude railway (the “permafrost rooster”) that traverses the Tibetan Plateau, and an avian virus (H5N1). This chapter considers multiple factors: the ecology of migratory birds, agricultural practices that mix wild and domestic birds, climate warming, and factory poultry farming. As a place at the crossroads of interconnected global phenomena such as avian influenza and climate change, the Qinghai case study provides a lens to envision the unintended consequences of natural and human forces over the coming decades.
Evaluation of Isolated Anti-HBc Positivity in Patients Considered for Hepatitis B Diagnosis: 8.5 Years of Data
Authors: Davarcı Ismail , Guducuoğlu Huseyin
Published: December 2024

Background: Hepatitis B virus (HBV) infection is a global health problem. Isolated anti-hepatitis B core (HBc) serologic pattern is the most common atypical serologic profile and is defined as positive anti-HBc and negative hepatitis B surface antigen (HBsAg) and anti-HBs. Objectives: This study aimed to determine the prevalence of isolated anti-HBc positivity in samples sent to the medical microbiology laboratory for the examination of hepatitis B indicators, to identify both anti-HBc IgM and HBV DNA positivity rates within this pattern, to examine the relationship of this atypical pattern with different clinics, and to contribute to the clinical data of our country. Methods: Between January 2015 and July 2023, the patients’ test results of HBsAg, anti-HBs, anti-HBc, anti-HBc IgM, and HBV DNA requested from blood samples were retrospectively scanned along with demographic data of these patients. Results: Isolated anti-HBc positivity was observed in 1941 (6.0%) patients. Hepatitis B virus DNA positivity was 8.4% and anti-HBc IgM positivity was 0.6% in patients with isolated anti-HBc positivity. In addition, isolated anti-HBc positivity increased by age, was more common in males, and in internal medicine units (gastroenterology, oncology, general internal medicine, etc.). Conclusions: Consequently, anti-HBc IgM and/or HBV DNA positivity within an isolated anti-HBc positive pattern shows the infectivity of the disease. For this reason, in the diagnosis of HBV, in addition to HBsAg and anti-HBs, anti-HBc also needs to be tested, and anti-HBc IgM and HBV DNA need to be checked in every patient with isolated anti-HBc positivity.

Authors: Jaberi Milad , Asadi Milad , Zarredar Habib , Shanehbandi Dariush , Zafari Venus , Pouresmaeil Ahmad , Sharifi Akbar
Published: December 2024

Background: The recent SARS-CoV-2 coronavirus pandemic has spread worldwide, with the first cases recorded in December 2019 in China. Symptoms include fever, cough, dyspnea, and gastrointestinal issues. Patients with SARS-CoV-2 are classified as mild, severe, or critical, highlighting the necessity for earlier treatment methods and reliable biomarkers. MicroRNAs have consistently been considered essential biological biomarkers. Objectives: In this case-control study, we investigated the levels of miR-26a and miR-125b in PBMCs of SARS-CoV-2 patients in northwestern Iran. Methods: Blood samples were collected from 100 COVID-19-infected patients, divided into two groups: 50 patients with no serious lung damage and 50 patients with COVID-19 infection and a lung abscess. RNA extraction techniques were used to examine PBMC specimens from COVID-19 patients. mRNA was extracted from WBCs, and the expression levels of miR-26a and miR-125b were evaluated using qRT-PCR in the two study groups. Results: The expression levels of miR-26a and miR-125b in PBMCs of patients with a poor prognosis were significantly lower compared to those with a good prognosis, as shown by qRT-PCR. The receiver operating characteristic (ROC) analysis indicated significant diagnostic potential for both miRNAs (miR-26a [area under the ROC curve (AUC)] = 0.8458, P < 0.0001; miR-125b AUC = 0.7944, P < 0.0001). Conclusions: The relative expression of miR-26a and miR-125b in SARS-CoV-2 infection was significantly different between the two study groups. These findings suggest their potential as disease severity indicators and prognostic markers.

Dichotomy or Continuum: Grice's Distinction between Natural and Nonnatural Meaning
Authors: Demir Mehmet Hilmi
Published: December 2024

Grice (1957), in his theory of meaning, introduced a distinction between two different types of meaning: nonnatural meaning and natural meaning. Grice’s distinction has been put to use in other areas of philosophy as well. Most famously, Dretske (1981, 1986) used Grice’s distinction in his naturalized epistemology. Scarantino and Piccinini (2010) offered a probabilistic alternative for semantic theories of information based on Grice's distinction. In both Dretske’s and Scarantino and Piccinini’s works, Grice’s distinction is assumed to form a dichotomy. This dichotomous nature, I claim, is at the root of some of the problems that afflict Dretske’s information-based naturalized epistemology and Scarantino and Piccinini’s probabilistic approach to information. In this paper, I suggest a revised version of Grice's distinction. In this revised version, instead of a dichotomy, natural and nonnatural meaning categories form a continuity, allowing overlapping and mixed intermediary categories between natural and nonnatural meaning. This continuous version, I further claim, provides more resources for avoiding some of the problems that afflict Dretske’s naturalized epistemology and Scarantino and Piccinini’s probabilistic approach to information.

Investigating the Link between Specific Personality Characteristics, Such As Conscientiousness and Extraversion, and Career Achievements and Job Satisfaction
Authors: Rao Muhammad Tauseef  , Taseer Abbas  , Rao Tahir Anees  , Dr Ali Ahsan Mufti
Published: December 2024

This study explores the relationships between personality traits—conscientiousness and extraversion—and career achievements and job satisfaction among teachers at Punjab University. A quantitative research design was employed, using a probability sampling technique to ensure that all teachers had an equal chance of being selected, resulting in a sample of 268 teachers. Data were collected through an online self-administered questionnaire, and responses were analyzed using regression, correlation, and ANOVA statistical techniques. The findings reveal a significant positive correlation between conscientiousness and both career achievements (r = 0.45, p = 0.001) and job satisfaction (r = 0.52, p = 0.000), indicating that teachers with higher conscientiousness tend to experience better career outcomes and report higher levels of job satisfaction. Regression analysis further confirms that extraversion significantly impacts both career success (B = 0.40, β = 0.42, p = 0.000) and job satisfaction (B = 0.33, β = 0.38, p = 0.000), with extraversion explaining 22% of the variance in career success and 15% in job satisfaction. When both conscientiousness and extraversion were analyzed together, both traits emerged as significant predictors of career success and job satisfaction, with extraversion showing a stronger effect. The study concludes that personality traits play a crucial role in shaping career outcomes and job satisfaction, suggesting that interventions designed to enhance these traits could improve both professional success and well-being for university teachers. This study underlines the importance of personality qualities in educational policy and teacher development and focuses on university professors from different academic backgrounds. The study studies the effect of the two fundamental qualities of the personality which are conscientiousness and extraversion on job satisfaction and career conquest. Conscientiousness is associated with reliability, work ethics and advancement of the career. The second one is extraversion that are associated with effective networking, interpersonal dynamics and leadership. These studies examine characteristics that affect job performance, satisfaction with a job and career achievement among the professors of the University of the Punjab. The quantitative methods used involved regression analysis and correlation. This study aims to demonstrate how conscientiousness and extraversion contribute to professional success and highlights the synergistic effects in the presence of both qualities.

Financial Distress and Earnings Management An Empirical Study of Non-Financial Firms Listed on the Indonesia Stock Exchange
Authors: Soraya Ayu Sheila , Arieftiara Dianwicaksih
Published: December 2024

This study examines the relationship between financial distress and earnings management among non-financial firms listed on the Indonesia Stock Exchange during the period 2018–2022. The research employs a quantitative approach using the modified Jones model to measure discretionary accruals, with leverage, firm size, and profitability included as control variables. The findings reveal that profitability has the strongest positive influence on earnings management, indicating that firms with higher profitability are more likely to manipulate earnings to enhance financial results and meet market expectations. Conversely, leverage demonstrates a significant negative effect, suggesting that firms with higher debt levels are less likely to engage in earnings manipulation due to increased creditor scrutiny and financial discipline. Meanwhile, financial distress and firm size have minimal impacts, with their coefficients showing no significant influence on discretionary accruals. These results highlight the importance of profitability and leverage as key drivers of earnings management while suggesting that financial distress and firm size play lesser roles in this context. The study acknowledges limitations, including its focus on non-financial firms in Indonesia, a five-year observation period, and the exclusion of additional factors like governance and macroeconomic conditions. Future research could address these limitations by expanding the dataset, incorporating more variables, and exploring other emerging markets.

Crisis communication in the city of Kraljevo: Situation and perspectives
Authors: Maksimović Zdravko , Kešetović Želimir
Published: December 2024

Crisis communication in the Republic of Serbia is not normatively regulated, and in the umbrella law there are only a few provisions related to offering timely and complete information to the public about risks and measures taken in crisis situations. Bearing in mind that the umbrella law located the responsibility for managing emergency situations primarily on local selfgovernment units, it logically follows that they are also responsible for crisis communication as integral and important part of crisis management. The paper analyzes the crisis communication of the city of Kraljevo in the period from 2014 to 2023. It points out the basic advantages of well organized crisis communication in the function of disaster risk reduction and emergency management, but also the shortcomings and observed errors, both in internal and external communication. In relation to the existing normative and institutional frameworks, the functioning is shown, not only during, but also before and after disasters, that is, in the course of extraordinary events/situations. The specific emergency situations that have befallen the territory of the city: floods, landslides and pandemics show the challenges and solutions of the situations that arose, when it comes to communication during the crisis, but also how the system learned from mistakes and improved. Of special importance for the crisis communication in the city of Kraljevo is the action of the Headquarters for emergency situations of the city of Kraljevo and the Department for Civil Protection Affairs, which functions within the City Administration of the city of Kraljevo. Functioning and communication before and after disasters in the city of Kraljevo, is based on the initiatives of the Department for Civil Protection Affairs and the presentation of that communication, especially with entities that are not part of the public administration system, whether it is local or state administration, will be shown as crucial for action and communication during disasters. The final evaluations represent recommendations for overcoming the observed shortcomings, as well as examples of good practice that other local governments in Serbia should recognize and implement in their crisis management, i.e., in this case, local staffs for emergency situations and planning documentation of importance for the processes and system of disaster risk reduction and emergency management.

Employee development represents both an imperative and a necessity for organizations strategically planning their business ventures and caring for their future, especially during the transition to Industry 5.0, where employees' knowledge, abilities, and motivations create a comparative advantage and bring significant benefits to organizations. The paper examines the developmental opportunities for employees through theoretical analysis and practical research, considering their subjective assessments, as well as managerial factors influencing development. The research was conducted on a sample of 480 employees, using standardized questionnaires. The first questionnaire measured developmental experiences using the Developmental Experiences Description Scale (Wayne et al., 1997), while the management style was assessed using the Supportive and Non-Controlling Supervision Scale (Oldham & Cummings, 1996). The results indicate modest assessments of development opportunities but suggest that a non-directive management model may have a positive impact on employee development.

Introduction: Sarcomas are rare tumors that account for less than 1% of malignant tumors in adults. Primary leiomyosarcoma (LMS) of the inferior vena cava (VCI) is a very rare tumor with an incidence of <1/100,000 of all malignant diseases in adults. This paper presents the case of a woman with LMS of the VCI who underwent radical tumor resection with vascular reconstruction. Case report: A 71-year-old woman went to the doctor because of painless hematuria. As part of the diagnostic evaluation, in addition to US and CT examination of the abdomen, CT angiography with 3D reconstruction was performed. The conclusion of the radiologist was that the described tumor mass first corresponds to a primary LMS of the VCI VCI that propagated laterally into the lumen of the left renal vein, while the right renal artery was infiltrated by the tumor. The patient was presented to the multidisciplinary team at the Institute for Oncology and Radiology of Serbia (IORS), which decided for operative treatment. The tumor was completely removed en bloc with the right kidney, right suprarenal gland and the confluence of the left renal vein into the VCI. The VCI was reconstructed with a graft with end-end anastomosis, while the left renal vein was implanted in the graft with end-side anastomosis. Conclusion: LMS of the VCI is an extremely rare tumor. Surgical resection of the tumor and the involved blood vessel with negative resection margins is the only therapeutic option that improves survival. Very often, in addition to complicated vascular reconstructions, surgery also includes multivisceral resections, in order to achieve the best possible therapeutic effect.

Introduction: Herpesviridae is a large family of double-stranded DNA viruses with eight types known to infect humans: Herpes simplex virus (HSV) type 1 and 2, Varicella zoster virus (VZV), Cytomegalovirus (CMV), Epstein Barr virus (EBV), Human herpesvirus (HHV) 6, 7 and 8. Herpetic eye disease can affect the anterior and/or posterior segment of the eye. In this article we focused on the anterior segment manifestations. Methods: A review of research articles with key words scleritis, keratitis, anterior uveitis, herpetic, HSV, VZV, CMV, and EBV published in PubMed database until April 30th, 2024 was done. Results: HSV1, VZV, and CMV are well known to cause inflammation in the anterior segment of the eye, which includes episcleritis, scleritis, keratitis, and anterior uveitis or their combination. However, there are reports of anterior segment inflammation caused by EBV, HSV2, or HHV6. The disease usually has a recurrent or chronic course and persistent inflammation can cause severe damage to the ocular tissues, which can significantly impair vision. Although some types of ocular inflammation can be effectively treated with antiviral agents during active phase of the disease (HSV1, HSV2, VZV, CMV), so far there is no final treatment which would permanently prevent the recurrences. The main complications include corneal scarring, scleral thinning, glaucoma, synechiae, iris atrophy, and cataract. Conclusion: Due to its recurrent or chronic course, the herpetic inflammation of the anterior segment of the eye remains a challenge for clinicians. While typical clinical clues may sometimes lead an ophthalmologist to suspect a herpetic cause of the inflammation, a definitive diagnosis-especially in atypical cases-can only be confirmed by PCR verification of the viral genome from ocular tissues or, in cases of uveitis, by detecting local specific antibody production in the aqueous humor using the Goldmann-Witmer coefficient.

Diagnosing Hirschsprung disease (HD) and related disorders can be complex and demands a deep understanding of the mechanisms governing intestinal motility, which involves the enteric nervous system (ENS), interstitial cells of Cajal (ICCs), and the muscle layers of the intestine. The London classification identifies three groups of gastrointestinal neuromuscular disorders: neuropathies, myopathies, and ICC abnormalities. Hirschsprung disease, characterized by the absence of ganglion cells, is the most common intestinal neuropathy and it results from the impaired migration of neural crest cells during development. It affects about 1 in 5,000 live births and involves several genetic factors, notably the RET gene. HD typically affects the rectum and a part of the colon, with varying extents of aganglionosis. The diagnosis is based on the histopathological analysis of suction biopsies, the absence of ganglion cells, and the presence of thick submucosal nerves on a standard hematoxylin and eosin stain, supplemented by enzyme histochemistry (acetylcholinesterase method) or immunohistochemical methods (calretinin and other antibodies) staining. The treatment for HD involves surgical resection of affected bowel segments. Accurate intraoperative assessment of tissue margins is critical to preventing postoperative complications related to pseudoobstruction. Communication between surgeons and pathologists is essential to ensure successful treatment outcomes. Other intestinal neuropathies include intestinal hypoganglionosis, hyperganglionosis, delayed maturation of ganglion cells, and gliopathies. Enteric myopathies are exceptionally rare conditions, with typical morphological changes such as atrophy of the muscularis propria, intracellular vacuolization of smooth muscle cells, and interstitial fibrosis. Disruption in ICC network and arrangement forms the morphological basis of slow transit constipation. Each of aforementioned disorders has unique characteristics and diagnostic challenges. Understanding and diagnosing these conditions often require a combination of histological, histochemical, immunohistochemical, and sometimes genetic analyses. The integration of these techniques is vital for accurate diagnosis and effective treatment planning. In summary, the complexity of intestinal dysmotility disorders necessitates a thorough understanding of intestinal motility mechanisms and the utilization of advanced diagnostic methods to provide accurate diagnoses and effective treatments.

Introduction: Trauma represents one of the most significant problems in public healthcare worldwide. It is one of the leading causes of mortality, particularly among children and young adults, but with a significant majority of non-fatal injuries that result in lifelong disabilities and health consequences. Proper and timely identification of patients with a higher risk of mortality is crucial for better outcomes in patients who suffer from trauma. The aim of this study is to identify potential predictors of in-hospital mortality among patients who suffered trauma and are treated in the ICU (Intensive Care Unit). Methods: The retrospective cohort study was conducted in a trauma, 12-bed ICU at the University Emergency Centre, University Clinical Centre of Serbia, Belgrade. All consecutive patients with blunt trauma were admitted to the ICU between August 2021 and August 2022. The primary outcomes of interest were all-cause in-hospital mortality. A value of p < 0.05 was considered statistically significant. Results: GCS (Hazard ratio 0.924 95%CI 0.873-0.979), vasopressors (Hazard ratio 3.47 95%CI 1.373-8.787) and age (Hazard ratio 1.030 95%CI 1.014-1.047) can independently predict in-hospital mortality. Conclusion:This study suggests risk factors for unfavorable clinical outcomes after severe trauma. It may be essential to properly and promptly differentiate between individuals with lower prognoses, which can lead to prompt and more aggressive treatment of these patients and might decrease in-hospital mortality. Age, vasopressors and mechanical ventilation, in particular, may be helpful indicators of in-hospital mortality of traumatized patients treated in the ICU.

In the modern environment there is undeniable evidence that climate change has a significant impact on economies at both regional and global levels. Also, there is increasing evidence that climate shocks and environmental risks have important implications for the financial stability of countries. Accordingly, all these developments impose the need for profound socioeconomic changes worldwide, aimed at promoting a "green economy". In practice, this entails a radical decarbonization of economies through transitions at all levels, which do not occur without compromise, conflict, or resistance. The aim of the paper is to highlight the importance of green macroeconomic policy for an environmentally and socially sustainable economic transition through a theoretical overview. The shift towards an ecologically sustainable economy will lead to significant changes, including the creation of new green jobs, industries, changes in existing jobs, and the gradual phasing out of some activities intensively using carbon. The fact that the social, economic and environmental benefits of such a transition have already been demonstrated globally, including the example of a good practice, this paper concludes with a proposition of potential measures to promote a just transition in Serbia.
