1912. Balloon aortic valvuloplasty (BAV) as a bridge to aortic valve replacement in cancer patients who require urgent non-cardiac surgeryPolonca Kogoj, Rok Devjak, Matjaž Bunc, 2014, original scientific article Abstract: Balloon aortic valvuloplasty (BAV) is a percutaneous treatment option for severe, symptomatic aortic stenosis. Due to early restenosis and failure to improve long term survival, BAV is considered a palliative measure in patients who are not suitable for open heart surgery due to increased perioperative risk. BAV can be used also as a bridge to surgical or transcatheter aortic valve implantation (TAVI) in hemodinamically unstable patients or in patients who require urgent major non-cardiac surgery.We reported 6 oncologic patients with severe aortic stenosis that required a major abdominal and gynecological surgery. In 5 cases we performed BAV procedure alone, in one patients with concomitant coronary artery disease we combined BAV and PCI. With angioplasty and BAV we achieved a good coronary artery flow and an increase in aortic valve area without any periprocedural complications. After the successful procedure, we observed a hemodynamic and symptomatic improvement. As a consequence the operative risk for non-cardiac surgery decreased and the surgical treatment was done without complications in all the 6 cases.We conclude that BAV can be utilized as a part of a complex therapy in severe aortic stenosis aimed to improve the quality of life, decrease the surgical risk for major non-cardiac surgery or as a bridge to surgical or transcatheter aortic valve implantation.

1913. Circulating serum sVCAM-1 concentration inadvanced ovarian cancer patients : correlation with concentration in ascitesMarina 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.

1917. Outward Bound and outdoor adventure education : a scoping review, 1995-2019Timothy J. Mateer, Joshua Pighetti, Derrick Taff, Pete Allison, 2022, original scientific article Abstract: Outdoor adventure education (OAE) programming is often referenced as an ef-fective intervention that encourages a wide array of outcomes in participants such as increased confidence, independence, and communication skills. However, as outdoor adventure education continues to increase globally, what does the academic literature say about the outcomes related to these programs? Hattie, Marsh, Neill, and Richards (1997) conducted the last major review of program efficacy in this realm. This updated scoping review, largely following PRISMA guidelines (Tricco et al., 2018), aims to summarize the academic literature on one of the primary outdoor adventure education providers internationally, Outward Bound (OB). Fifty-four studies, published betwe-en 1995 and 2019, have been summarized in this review. Utilizing Outward Bound International’s (OBI) framework of “people”, “place”, and “process”, themes and gaps in the literature are explored. Specifically, the OB literature has progressed since 1995 in demonstrating social and emotional outcomes in a variety of settings, a better understanding of the nature of effective programming, and further documenting the role the instructor plays in the learning experience. Recommendations are provided on developing more rigorous methodologies for future research, understanding the role of the physical environment in the learning experience, and utilizing theoretical approa-ches to integrate outdoor adventure education into broader academic realms

1920. Body composition of young soccer playersErol Kovačević, Denis Čaušević, Seth Spicer, Siniša Kovač, Ivor Doder, Slavenko Likić, Boris Metikoš, 2022, original scientific article Abstract: Purpose:The main aim of this study was to examine and analyse the body composi-tion of young soccer players across different age groups.Methods: A cross-sectional study was carried out among 126 young soccer players divided into age categories: U15 – 53 players (age=14.68±0.47); U17 – 51 players (age=16.47±0.50); U19 – 22 players (age=18.05±0.38). The subjects’ height was mea-sured using an anthropometer, while their body composition was measured using the TANITA BC-420MA digital scale. Results: On average, soccer players in the U15 group had significantly lower body height, weight, body mass index and fat free mass than U17 and U19 players, but had a higher percentage of body fat (p < 0.05). In addition to the percent of body fat mass, which tends to significantly decrease with age, the results also demonstrate significant non-linear increases in body height, weight, and lean body composition concurrent with the players’ ages.Conclusion:These results indicate that younger soccer players have lower abso-lute values of morphological characteristics compared to senior players.
