262. Chemokines during anaphylaxis : the importance of CCL2 and CCL2-dependent chemotactic activity for basophilsRomana Vantur, Maruša Rihar, Ana Koren, Matija Rijavec, Peter Kopač, Urška Bidovec, Renato Eržen, Peter Korošec, 2020, izvirni znanstveni članek Povzetek: Background: The role of chemokines in anaphylaxis is unclear. Methods: We prospectively recruited 49 patients presenting to the emergency department with an acute episode of anaphylaxis and 28 healthy subjects. We measured serum levels of the chemokines CCL2, CCL5, CCL7, CCL8, CCL11, CCL13, CCL17, CCL21, CCL22, CCL24, and CCL26, tryptase, the absolute number of circulating basophils, monocytes, lymphocytes, and PMNs, and whole blood FCER1A, CPA3 and HDC gene expression at two time points: during the anaphylactic episode and in convalescent samples collected approximately 3 months later. We then investigated the in vitro chemotactic activity of chemokines induced during anaphylaxis for the in vitro migration of the corresponding cells. Results: Only CCL2 chemokine levels were signifcantly increased in anaphylaxis samples (median 514 pg/ml) compared to convalescent samples (284 pg/ml, P<0.0001) and healthy subjects (279 pg/ml, P<0.0001); there was no signifcant diference in any of the other chemokines. There was a signifcant positive correlation between the rates of increase of serum CCL2 (median [range]: 106.0% [-44.7% to 557.4%]) and tryptase (133.8% [-6.6% to 893.4%]; r=0.68, P<0.0001) and between the acute concentration of serum CCL2 and the acute concentration of serum tryptase (r=0.77, P<0.0001). The number of circulating basophils, but not other blood cells, signifcantly decreased during anaphylaxis (median 5.0 vs. 19.1 cells/[micro]l in convalescent samples; P<0.0001); a decrease in whole-blood gene expression of basophil markers (PKljučne besede: anaphylaxis, chemokines, tryptases, basophils, chemotaxis, CCL2, cell migration

264. Težke odločitve pri zdravljenju bolnikov z vensko trombembolijo in rakomAna Kovač Bograf, Monika Štalc, Gregor Tratar, Alenka Mavri, 2016, pregledni znanstveni članek Povzetek: Venska trombembolija (VTE) je pogost zaplet pri bolnikih z rakom. Zdravljenje VTE pri teh bolnikih predstavlja velik izziv, saj je pri bolnikih z rakom dodatno povečano tako tveganje za trombembolične zaplete kot tudi tveganje za krvavitve. Predstavili bomo nekaj kliničnih situacij, s katerimi se v klinični praksi pogosto srečamo in predstavljajo dileme pri antikoagulacijskem zdravljenju bolnikov z VTE ter rakom, in sicer ponovitve VTE kljub zdravljenju, pojav trombocitopenije, tumorje osrednjega živčevja, uporabo filtrov v spodnji votli veni, uporabo novih peroralnih antikoagulacijskih zdravil in pojav naključno odkrite VTE.

266. Quantitative, absolute count-based T cell analysis of CD69 upregulation as a new methodology for in vitro diagnosis of delayed-type nickel hypersensitivityAna Koren, Mira Šilar, Helena Rupnik, Mihaela Zidarn, Peter Korošec, 2019, izvirni znanstveni članek Povzetek: Background: T cells play a major role in delayed-type hypersensitivity reactions. Their reactivity can be assessed by measuring the upregulation of the activation marker CD69, followed by proliferation and cytokine production. The aim of our study was to develop a novel, whole blood-based, quantitative, absolute count activation index (AI) analysis of CD69 upregulation on different subsets of T cells in nickel hypersensitive patients and compare it with the previously reported approaches. Methods: Ten patients with nickel allergy and nine healthy controls were included. CD69 expression of CD3+, CD3+CD4+ and CD3+CD8+ T cells in heparinized blood was determined with flow cytometry after incubation with nickel sulfate for 48 h. The absolute cell count of CD69+ cells was determined with microbeads. The production of the cytokines IL-2, IL-5, IL-13, and IFN-[gamma] was determined after nickel sulfate stimulation of PBMNCs for 48 h. Results: We showed that the most sensitive methodology is the absolute AI, which was calculated as the ratio between the absolute count of CD69-positive T cells stimulated with nickel and the absolute count of CD69-positive T cells in non-stimulated blood. This novel quantitative approach was more discriminative than the previously reported approaches in which T cell CD69 percentage AI and cytokine production are measured. Conclusions: Our results demonstrated that measuring the absolute CD69 AI is an accurate new approach to quantify antigen-specific T cells in the blood of patients with hypersensitivity reactions to nickel. This approach may be useful for better in vitro assessment of patients with delayed-type hypersensitivity reactions.

267. Using citizen science to monitor the spread of tree pests and diseases : outcomes of two projects in Slovenia and the UKPeter Crow, Ana Pérez-Sierra, Andreja Kavčič, Kate Lewthwaite, Marija Kolšek, Nikica Ogris, Barbara Piškur, Jana Kus Veenvliet, Simon Zidar, Suzanne Sancisi-Frey, Maarten De Groot, 2020, izvirni znanstveni članek Povzetek: The trees and forests of Europe are increasingly under threat from new pests and diseases that have originated in other parts of the world. Early detection of alien species when they first appear in European countries allows rapid response and offers the best chance to mitigate against their establishment and spread. Citizen science initiatives such as LIFE ARTEMIS in Slovenia, and Observatree in the UK, provide members of the public with the necessary training and educational resource to identify these tree pests and diseases and report them to the appropriate authorities, thereby increasing the level of surveillance and the capacity of the early warning system. This paper summarises some of the outcomes of these two projects and how they have both become integral parts of the official forest and tree health monitoring systems within their respective countries of Slovenia and the United Kingdom.

269. Pomen biovarnosti za zdravje gozdov : pregled izkušenj iz tujine in predlogi za SlovenijoAna Brglez, Peter Smolnikar, Barbara Piškur, 2020, strokovni članek Povzetek: V letu 2020 obeležujemo mednarodno leto zdravja rastlin. V kmetijstvu in vrtnarstvu je pojem zdravja rastlin dobro znan, medtem ko se za naravno okolje vse premalokrat omenja. Gozdove ogrožajo številni domači in tujerodni organizmi, ki jim naša dejavnost v okolju omogoča vse lažje in hitrejše širjenje v prostoru. Za preprečitev oz. omejevanje širjenja je ključno delovanje fitosanitarnih inšpekcij in nadzora na mejah ob vstopu tujega blaga, na lokalnem nivoju pa ozaveščenost strokovnih služb, lastnikov zemljišč ter vseh obiskovalcev narave, da upoštevajo osnovne ti. biovarnostne ukrepe. Biovarnost je skupek ukrepov, ki zmanjšajo ali v celoti preprečijo vnos in prenos škodljivih organizmov z ene lokacije na drugo. Po navadi ukrepi zajemajo čiščenje oblačil, obutve, vozil in opreme vseh organskih ostankov rastlin in zemlje ter pregled notranjosti vozila glede prisotnosti žuželk. V prispevku predstavljamo kot primer dobre prakse ozaveščanja o pomenu biovarnosti v gozdovih obširno akcijo Združenega kraljestva Keep it clean ter iščemo ovire in priložnosti za rabo pri nas. V Sloveniji je pojem biovarnosti uveljavljen v kmetijstvu (npr. v prašičjereji in hmeljarstvu), v gozdarstvu pa je dokaj neznan. Z zakonsko dovoljenim prostim dostopom v gozd, gosto mrežo gozdnih cest in v zadnjem času povečanim obiskom gozdov je ob morebitni prisotnosti škodljivih organizmov potencial za njihovo hitro razširjenje izjemno velik. Vendar pa je tudi prostora za izboljšanje sedanje situacije še veliko. Med priložnostmi lahko izpostavimo ozaveščanje v smeri higiene in ukrepov, ki so potrebni za preprečitev vnosa in prenosa škodljivih organizmov, posodobitev veljavne zakonodaje na področju zdravja rastlin in gozdarstva, njuno uskladitev z veljavno evropsko zakonodajo ter nadzor nad njihovim izvajanjem. Nikakor pa ne smemo pozabiti na največjo priložnost vsakega izmed nas, da se vede odgovorno do okolja, v katerem živimo.
