Association of Image-Defined Risk Factors with Clinical, Biological Features and Outcome in Neuroblastoma
No full textBackground: Neuroblastoma (NB) is the most common pediatric extracranial solid tumor and the most common cancer encountered in children younger than 12 months of age. Localized tumors have a good prognosis, but some cases undergo treatment failure and recurrence. The aim of the study was to analyze the link between the neuroblastoma risk factors and the prognosis for patients diagnosed with NB. Method: All patients admitted to the department of Pediatric Surgery, “Grigore Alexandrescu” Clinical Emergency Hospital for Children, between 1 January 2010 and 1 July 2022 were included in this analysis when diagnosed with neuroblastoma. Results: Thirty-one patients with NB were admitted to the surgical department, 20 boys and 11 girls. We observed an association between large tumors and positive imaging-defined risk factor (IDRF) status; The Fisher test showed an association between the tumor’s diameter when bigger than 8 cm and a positive IDRF status, with p < 0.001. We supposed that positive IDRF status at diagnosis may be linked to other prognostic factors. We discovered that an NSE value over 300 was associated with IDRF status (p < 0.001, phi = 0.692) and death. Conclusions: This study confirms the impact of IDRF status at diagnosis as it can be clearly correlated with other risk factors, such as a high level of NSE, MYCN amplification status, large tumor size, incomplete tumor resection, and an unfavorable outcome

ADVANCING NATO'S QUALITY ASSURANCE EDUCATION BY IMPLEMENTING THE 'LEARN-WATCH-ASK' TRAINING MODEL
No full textThe paper introduces a detailed analysis and a method of implementing the "Learn-Watch-Ask" (LWA) training model, as a potential solution, to enhance quality assurance training within NATO. By addressing the fast-evolving demands of specialized domains, the LWA model integrates digital tools with traditional teaching methods to create a learning experience that is responsive to the student`s needs. The model is comprised of three interdependent components: the Learn module, represented by a structured online course; the Watch module, supported by a specialized YouTube channel for enhanced visual understanding; and the Ask module, created with an AI-driven chatbot for interactive learning. This innovative approach supports diverse learning styles, offering 24/7 accessibility and effectiveness. The paper further digs deeper into the identified shortcomings of traditional training models, emphasizing the need for practical, visual, and interactive elements in modern education. It explores the integration of the IBM WatsonX Assistant as a conversational AI chatbot in the LWA model, highlighting its advantages in providing consistent, accurate, and user-friendly interactions over Generative Pre-Trained (GPT) AI models. Additionally, a 7-step process for adapting the LWA model to various domains is outlined, as well as the description of a comprehensive continuous improvement loop for the IBM WatsonX Assistant, ensuring its relevance and efficiency in the rapidly evolving educational landscape. The LWA model, with its unique approach to modern educational techniques, not only enhances the learning experience for NATO’s Quality Assurance Course (M7-137) but also has the potential to be adapted across various specialized domains, promising a more effective and efficient workforce
UGOVOR O RADU NA ODREĐENO VREME U NEMAČKOM PRAVU
No full textIn this paper, the author analyzes the fixed-term employment contract in German law highlighting the importance of this contract in a flexible employment environment. However, making a fixed-term employment contract is considered to be an exception, thus the objective reason which justifies its use is established in German law. This indicates that a fixed-term employment contract is a desirable means for creating an employment relationship only if the conditions provided by law are met. Therefore, the conditions under which the fixed-term contract can be used, the number of renewals and the maximum length of the total duration are mentioned. Additionally, the paper presents ‘legislative history’ of the fixed-term employment contract after its conceptual definition. At the end, the author points to the prohibition of discrimination against atypical employees stating that those employees must not have any less rights compared to the rest of the employees working for the same employer, especially those with the standard employment contract.U radu autorka analizira ugovor o radu na određeno vreme u nemačkom pravu ukazujući na značaj koji taj ugovor ima u fleksibilnom radnopravnom okruženju. Ipak, zaključivanje ugovora o radu na određeno vreme se smatra izuzetkom, zbog čega se u nemačkom pravu izgrađuje princip objektivnog razloga koji opravdava njegovu upotrebu. To znači da se ugovor o radu na određeno vreme smatra poželjnim instrumentom za zasnivanje radnog odnosa samo ako su za to ispunjeni zakonom predviđeni uslovi. Otuda se u radu navode dopušteni slučajevi, ograničenja u korišćenju ugovora o radu kroz limitiranje broja sukcesivnih ugovora i maksimalne dužine ukupnog trajanja ugovora. U radu se prikazuje i „legislativna istorija” ugovora o radu na određeno vreme, nakon njegovog pojmovnog određenja. Na samom kraju se ukazuje na zabranu diskriminacije atipičnih zaposlenih koji ne smeju uživati manje prava u poređenju sa drugim zaposlenima kod poslodavca, posebno onim sa standardnim ugovorom o radu
PREVENCIJA ZLOSTAVLjANjA NA RADU
No full textIn this paper, the author discusses the phenomenon of mobbing, or harassment at the workplace, by focusing on the concept, phenomenological characteristics and types of mobbing, the etiological factors leading to its emergence, and the consequences sustained by victims. Considering the need to have mobbing recognized and legally sanctioned as a form of harassment, the author underscores that the social response to mobbing must be conceived as a comprehensive system of preventive measures. This paper aims to provide an insight into this negative social phenomenon as a prerequisite for building an effective system of primary, secondary and tertiary prevention. In particular, the author provides an overview of the Serbian legislation on this matter and points to the role of the non-governmental sector in the prevention of mobbing.Mobing ili zlostavljanje na radu ne spada u red novijih pojava, s obzirom na to da postoji od kada i razlike u pozicijama moći vezane za rad i radno okruženje. Ono što je novo, jeste zahtev društvene zajednice da mobing, kao oblik zlostavljanja, bude prepoznat i pravno normiran. Na tom putu, glasnogovornici borbe protiv mobinga ističu značaj primene preventivnih mera. Tranziciono društvo, u kome vlada siva ekonomija i visoka stopa nezaposlenosti, idealno je tlo za razvoj ovog oblika zlostavljanja, te ono vapi za obuhvatnim i sistemskim preventivnim rešenjima. U cilju efikasnog koncipiranja preventive neophodno je precizno odrediti šta je mobing, koji su njegovi pojavni oblici, uzroci javljanja i posledice. Celovito sagledavanje i razumevanje ovog negativnog društvenog fenomena je uslov izgradnje delotvornog sistema primarne, sekundarne i tercijarne prevencije
Nerone ritrovato
No full textThe author discusses in detail the dating of a marble head of the emperor Nero, recently identified in a collection in London. It will have belonged to a largerthanlife loricata statue and will have been detached from it when the emperor suffered damnatio memoriae. The details indicate the date of its manufacture in the last period of the reign, 64–68 AD; it appears to be the very latest ancient representation of the emperor. All available data supports the authenticity of this portrait.
Keywords: Nero, head of a statue, authentic, marble, last period of the reign
Our Experience with Cyst Excision and Hepaticoenterostomy for Choledocal Cyst: A Single Center Case Review of 16 Patients
No full textBackground and Objectives: Choledocal cyst is a rare congenital disease of the biliary tree defined by dilatation of the extrahepatic and/or intrahepatic biliary ducts. Untreated, it leads to complications such as cholangitis, stone formation and malignant degeneration. The standard treatment for choledocal cyst is complete excision and subsequent biliary reconstruction via hepaticojejunostomy or hepatiocoduodenostomy. Materials and Methods: We report our experience with 16 pediatric cases of choledocal cyst over a 10-year period. Results: The predominant symptoms were nausea and jaundice, both at 62.5% (n = 10), followed by abdominal pain at 56.3% (n = 9). Ultrasonography was the diagnostic method used in all patients. Computed tomography was used in 75% (n = 12) and magnetic resonance imaging in 25% (n = 4) of cases. Age at the time of intervention ranged from 2 months to 17 years with a mean of 4 years and 5 months. The open approach was used in nine patients and the laparoscopic approach was used in seven patients, with one conversion to open surgery. Complete excision of the choledocal cyst was performed in 15 cases (93.7%), and partial excision with mucosectomy was performed in one case (6.2%). Eight patients (50%) underwent hepaticoduodenostomy and eight (50%) underwent hepaticojejunostomy, out of which one was attempted laparoscopically but was converted. We had a postoperative complication rate of 12.5% (n = 2) represented by anastomotic leak and pancreatitis. Conclusions: From our experience with these cases, we concluded that a wide hepaticoduodenostomy constitutes a favorable choice over the traditional hepaticojejunostomy, being more physiological and less time consuming
