1731. Echocardiography and cardiac biomarkers in patients with non-small cell lung cancer treated with platinum-based chemotherapyDaniel Omersa, Tanja Čufer, Robert Marčun, Mitja Lainščak, 2017, original scientific article Abstract: Background. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and remains an important cause of cancer death worldwide. Platinum-based chemotherapy (PBC) for NSCLC can modify outcome while the risk of cardiotoxicity remains poorly researched. We aimed to evaluate the incidence and severity of cardiac injury during PBC in patients with NSCLC and to identify patients at risk. Methods. This was a single-centre, prospective, observational study of patients with early and advanced stage NSCLC referred for PBC. In addition to standard care, patients were examined and evaluated for cardiotoxicity before the first dose (visit 1), at the last dose (visit 2) and 6 months after the last dose of PBC (visit 3). Cardiotoxicity (at visit 2 and 3) was defined as increase in the ultrasensitive troponin T, N-terminal pro-B type natriuretic peptide or decrease in left ventricular ejection fraction (LVEF). Results. Overall, 41 patients (mean age 61 +/- 9; 54% men; 68% advanced lung cancer) were included. The median number of PBC cycles was 4. During the study period, there were no incidents of heart failure, and 3 deaths caused by tumour progression were recorded. The mean values of biomarkers and LVEF did not change significantly (p > 0.20). However, 10 (25%) had cardiotoxicity which was independently associated with a history of ischemic heart disease (p = 0.026). Conclusions. In NSCLC, cardiac assessment and lifestyle modifications may be pursued in patients with a history of cardiac disease and in patients with longer life expectancy.

1733. Slovensko slovstvo v Istri pred prvo svetovno vojno : opis slovenskega knjižnega fonda pri sv. Ani v KopruDiana Košir, 2024, other scientific articles Abstract: Knjižni fond samostanske knjižnice sv. Ane je najbolj natančno popisan v inventarni knjigi Zbirnega centra knjižnic v Portorožu (1950–1953). Samostan, ki je pred 1. sv. vojno pripadal hrvaški provinci, je v svoji knjižnici hranil tudi slovenske tiske. Prispevek prinaša pregled in besedilnozvrstni opis slovenskih del v popisu, ki kažejo na to, da so koprski frančiškani liturgične in pastoralne dejavnosti opravljali tudi v slovenščini in tako gojili domačo besedo med slovenskimi verniki, obsežen nabor posvetnega strokovno-didaktičnega gradiva pa je bil namenjen jezikovni in splošni izobrazbi.

1738. Red blood cell transfusion and skeletal muscle tissue oxygenation in anaemic haematologic outpatientsMatej Podbregar, Ana Uršula Gavrič, Eva Podbregar, Hugon Možina, Sebastian Stefanović, 2016, original scientific article Abstract: Background. Stored red blood cells (RBCs) accumulate biochemical and biophysical changes, known as storage lesion. The aim of this study was to re-challenge current data that anaemia in chronically anaemic haematology patients is not associated with low skeletal muscle tissue oxygen (StO2), and that RBC storage age does not influence the tissue response after ischaemic provocation, using near-infrared spectroscopy. Patients and methods. Twenty-four chronic anaemic haematology patients were included. Thenar skeletal muscle StO2 was measured at rest (basal StO2), with vascular occlusion testing (upslope StO2, maximum StO2) before and after transfusion. Results. Basal StO2 was low (53% +- 7%). Average RBC storage time was 10.5 +- 3.9 days. Effects of RBC transfusions were as follows: basal StO2 and upslope StO2 did not change significantly; maximum StO2 increased compared to baseline (64 +- 14% vs. 59 +- 10%, p = 0.049). Change of basal StO2, upslope StO2 and maximum StO2 was negatively related to age of RBCs. The decrease of maximum StO2 was predicted (sensitivity 70%, specificity 100%), after receiving RBCs >- 10days old. Discussion. Resting skeletal muscle StO2 in chronic anaemic patients is low. RBC storage time affects skeletal muscle StO2 in the resting period and after ischaemic provocation.

1740. Antioxidant defence-related genetic variants are not associated with higher risk of secondary thyroid cancer after treatment of malignancy in childhood or adolescenceAna Lina Vodušek, Katja Goričar, Barbara Gazić, Vita Dolžan, Janez Jazbec, 2016, original scientific article Abstract: Background. Thyroid cancer is one of the most common secondary cancers after treatment of malignancy in childhood or adolescence. Thyroid gland is very sensitive to the carcinogenic effect of ionizing radiation, especially in children. Imbalance between pro- and anti-oxidant factors may play a role in thyroid carcinogenesis. Our study aimed to assess the relationship between genetic variability of antioxidant defence-related genes and the risk of secondary thyroid cancer after treatment of malignancy in childhood or adolescence. Patients and methods. In a retrospective study, we compared patients with childhood or adolescence primary malignancy between 1960 and 2006 that developed a secondary thyroid cancer (cases) with patients (controls), with the same primary malignancy but did not develop any secondary cancer. They were matched for age, gender, primary diagnosis and treatment (especially radiotherapy) of primary malignancy. They were all genotyped for SOD2 p.Ala16Val, CAT c.-262C>T, GPX1 p.Pro200Leu, GSTP1 p.Ile105Val, GSTP1 p.Ala114Val and GSTM1 and GSTT1 deletions. The influence of polymorphisms on occurrence of secondary cancer was examined by McNemar test and Cox proportional hazards model. Results. Between 1960 and 2006 a total of 2641 patients were diagnosed with primary malignancy before the age of 21 years in Slovenia. Among them 155 developed a secondary cancer, 28 of which were secondary thyroid cancers. No significant differences in the genotype frequency distribution were observed between cases and controls. Additionally we observed no significant influence of investigated polymorphisms on time to the development of secondary thyroid cancer. Conclusions. We observed no association of polymorphisms in antioxidant genes with the risk for secondary thyroid cancer after treatment of malignancy in childhood or adolescence. However, thyroid cancer is one of the most common secondary cancers in patients treated for malignancy in childhood or adolescence and the lifelong follow up of these patients is of utmost importance.
