International Conference Decade of Decadence: 1914–1924 : spaces, societies and belongings in the Adriatic borderland in historical comparison
2024, other monographs and other completed works

Abstract: Historians have long come to realize the importance of the World War I as the seminal event leading to a short 20th century. If traditional research has often conceptualized the war and post-war years as two distinct historical periods, new studies have emphasized entangle-ments and intertwinements between war- and post-war processes. This turn was influenced by a gradual geographical balance and the inclusion of Eastern and Central Europe in the re-search focus. Wars, collapse of Empires and long-existing State structures, and similar events brought about processes of redefinition of territories and its peoples. The focus on volatile, overlapping and, at times, competing centers of power (States, national, regional and local structures), will allow us to reconsider criteria and concepts of citizenship and belonging that have shaped European politics of governance. Our conference focuses on the Northern Adri-atic transnational borderland from the beginning of World War I in July 1914 to the Treaty of Rome in January 1924, when the Adriatic question was temporarily settled. This decade is of fundamental importance at the global level, while the Northern Adriatic represents a unique laboratory to study the transformations of Europe in the Twentieth Century. The focus is on the question of citizenship beyond nation-state frameworks and monothematic disciplines, in which the question of citizenship is linked to the migratory movement of people. Taking the Northern Adriatic as a case study, this conference aims at rethinking the questions of citizen-ships, national affiliations, territorial belongings and state sovereignty. This will enable us to contribute to a growing dialogue in international academia and to contemporary societal de-bates at a time, when citizenship and the rights linked to it are the subject of intense discus-sions. We aim at reconsidering rigid understandings of center and periphery and restoring a more composite history of twentieth century Europe.

The coastal ichthyofauna of the Mediterranean coral reef : the case of Mljet National Park (Croatia, southern Adriatic Sea)
Lovrenc Lipej, Danijel Ivajnšič, Valentina Pitacco, Borut Mavrič, Domen Trkov, Petar Kružić, 2024, original scientific article

Abstract: The authors studied the structure of the coastal fish assemblage in a temperate coral reef within a marine protected area in order to provide a baseline information on the occurrence and temporal distribution of fish and to highlight the importance of the coral reef to ichthyofauna. The coastal fish assemblage was investigated at two sites in Veliko jezero (Mljet National Park) in the southern Adriatic Sea with a non-destructive SCUBA visual technique in the period from 2013 to 2021. Altogether, 38 fish taxa were recorded on the right bank (coral reef) and 36 species on the left bank. The presence of the coral reef at a depth range between 9 m to 12 m is the main factor differentiating the fish fauna in these two areas, which are otherwise governed by the same environmental factors. At the coral reef a decrease in fish diversity was discovered with a steady regression from 2013 to 2021.

The role of neoadjuvant chemotherapy in patients with advanced (stage IIIC) epithelial ovarian cancer
Erik Škof, Sebastjan Merlo, Gašper Pilko, Borut Kobal, 2016, original scientific article

Abstract: Primary treatment of patients with advanced epithelial ovarian cancer consists of chemotherapy either before (neoadjuvant chemotherapy, NACT) or after primary surgery (adjuvant chemotherapy). The goal of primary treatment is no residual disease after surgery (R0 resection) what is associated with an improvement in survival of patients. There is, however, no evidence of survival benefits in patients with R0 resections after prior NACT. Methods. We retrospectively reviewed the records of patients who were treated with diagnosis of epithelial ovarian cancer at Institute of Oncology Ljubljana in the years 2005%2007. The differences in the rates of R0 resections, progression free survival (PFS), overall survival (OS) and in five-year and eight-year survival rates between patients treated with NACT and patients who had primary surgery were compared. Results. Overall 160 patients had stage IIIC epithelial ovarian cancer. Eighty patients had NACT and eighty patients had primary surgery. Patients in NACT group had higher rates of R0 resection (42% vs. 20%; p = 0.011) than patients after primary surgery. PFS was 14.1 months in NACT group and 17.7 months after primary surgery (p = 0.213). OS was 24.8 months in NACT group and 31.6 months after primary surgery (p = 0.012). In patients with R0 resections five-year and eight-year survival rates were 20.6% and 17.6% in NACT group compared to 62.5% and 62.5% after primary surgery (p < 0.0001), respectively. Conclusions. Despite higher rates of R0 resections achieved by NACT, survival of patients treated with NACT was inferior to survival of patients who underwent primary surgery. NACT should only be offered to patients with advanced epithelial cancer who are not candidates for primary surgery.

Obstructive urination problems after high-dose-rate brachytherapy boost treatment for prostate cancer are avoidable
Borut Kragelj, 2016, original scientific article

Abstract: Aiming at improving treatment individualization in patients with prostate cancer treated with combination of external beam radiotherapy and high-dose-rate brachytherapy to boost the dose to prostate (HDRB-B), the objective was to evaluate factors that have potential impact on obstructive urination problems (OUP) after HDRB-B. Patients and methods. In the follow-up study 88 patients consecutively treated with HDRB-B at the Institute of Oncology Ljubljana in the period 2006-2011 were included. The observed outcome was deterioration of OUP (DOUP) during the follow-up period longer than 1 year. Univariate and multivariate relationship analysis between DOUP and potential risk factors (treatment factors, patients% characteristics) was carried out by using binary logistic regression. ROC curve was constructed on predicted values and the area under the curve (AUC) calculated to assess the performance of the multivariate model. Results. Analysis was carried out on 71 patients who completed 3 years of follow-up. DOUP was noted in 13/71 (18.3%) of them. The results of multivariate analysis showed statistically significant relationship between DOUP and anticoagulation treatment (OR 4.86, 95% C.I. limits: 1.21-19.61, p = 0.026). Also minimal dose received by 90% of the urethra volume was close to statistical significance (OR = 1.23; 95% C.I. limits: 0.98-1.07, p = 0.099). The value of AUC was 0.755. Conclusions. The study emphasized the relationship between DOUP and anticoagulation treatment, and suggested the multivariate model with fair predictive performance. This model potentially enables a reduction of DOUP after HDRB-B. It supports the belief that further research should be focused on urethral sphincter as a critical structure for OUP.

Circulating serum sVCAM-1 concentration inadvanced ovarian cancer patients : correlation with concentration in ascites
Marina Jakimovska, Katarina Černe, Ivan Verdenik, Borut Kobal, 2014, original scientific article

Abstract: Background. Vascular cell adhesion molecule-1 (VCAM-1) is associated with ovarian cancer progression but theorigin of its soluble form (sVCAM-1) in serum is not well investigated. The purpose of this study was to elucidate whetherthe concentration of sVCAM-1 in serum correlates with the concentration in ascites, that represents local tumour environment,and with systemic inflammation, various clinicopathological characteristics, and patient outcome.Patients and methods. Thirty-six patients with advanced ovarian cancer were included in the study. Serum forsVCAM-1 analysis was obtained prior to surgery. Ascites samples were collected at the beginning of the operation.Clinical data were collected from patients medical records. sVCAM-1 in samples was analysed by flow cytometricbead-based assay. The mean follow-up period was 11 months (range 0-23) from the time of surgery.Results. Serum sVCAM-1 concentrations are positively correlated to ascites sVCAM-1 concentrations. There was aweakly positive correlation of serum sVCAM-1 with tumour size and no correlation with inflammatory tumour markers,FIGO stage or grade. Higher concentrations of sVCAM-1 were associated with poor disease outcome (death fromovarian cancer) in almost all cases before chemotherapy was started.Conclusion. This is the first study demonstrating that serum concentrations of sVCAM-1 in advanced ovarian cancerpatients correlate with sVCAM-1 concentrations in ascites, thus expressing the biologic potential of malignant diseaseto metastasis, rather than systemic inflammation. Higher serum and ascites sVCAM-1 concentrations might have predictivepotential for different biologic behaviour.

Microsatellite instability in colorectal cancer
Matej Horvat, Borut Štabuc, 2011, review article

Abstract: Background. Colorectal cancer (CRC) is the third most common cancer in the world. In 75% CRC develops sporadically, in 25% hereditary or as a consequenceof inflammatory bowel disease. CRC carcinogenesis develops over many years. The cause of CRC in 85% is chromosomal instability (CIN) and in 15% microsatellite instability (MSI-H), where hereditary nonpolyposis colorectal cancer (HNPCC) represents 10-20%. Microsatellite sequences (MS) arerepeated sequences of short stretches of DNA all over the genome. Microsatellite stability (MSS) means MS are the same in each cell of an individual, whereas microsatellite instability (MSI-H) means MS differ in normal and cancer cells of an individual. The cause of MSI-H is a damaged mismatch repair mechanism (MMR), with the most important MMR proteins being MSH2, MLH1 and MSH6. Conclusions. MSI-H seems to be an important prognostic factor in CRC and an important predictive factor of CRC chemotherapeutic treatment efficacy. Clinical trials conducted until now have shown contradictory findings in different chemotherapeutic settings, adjuvant and palliative; therefore MSI-H is going to be the object of the future research. The future of cancer treatment is in the individualized therapy based on molecular characteristics of the tumour, such as MSI-H in CRC.
