61. Heritable risk for severe anaphylaxis associated with increased [alpha]-tryptase-encoding germline copy number at TPSAB1Jonathan J. Lyons, Jack Chovanec, Michael P. O'Connell, Yihui Liu, Julij Šelb, Roberta Zanotti, Yun Bai, Jiwon Kim, Quang T. Le, Tom DiMaggio, Matija Rijavec, Peter Korošec, 2020, original scientific article Abstract: Background: An elevated basal serum tryptase level is associated with severe systemic anaphylaxis, most notably caused by Hymenoptera envenomation. Although clonal mast cell disease is the culprit in some individuals, it does not fully explain this clinical association. Objective: Our aim was to determine the prevalence and associated impact of tryptase genotypes on anaphylaxis in humans. Methods: Cohorts with systemic mastocytosis (SM) and venom as well as idiopathic anaphylaxis from referral centers in Italy, Slovenia, and the United States, underwent tryptase genotyping by droplet digital PCR. Associated anaphylaxis severity (Mueller scale) was subsequently examined. Healthy volunteers and controls with nonatopic disease were recruited and tryptase was genotyped by droplet digital PCR and in silico analysis of genome sequence, respectively. The effects of pooled and recombinant human tryptases, protease activated receptor 2 agonist and antagonist peptides, and a tryptase-neutralizing mAb on human umbilical vein endothelial cell permeability were assayed using a Transwell system. Results: Hereditary [alpha]-tryptasemia (H[alpha]T)--a genetic trait caused by increased [alpha]-tryptase-encoding Tryptase-[alpha]/[beta]1 (TPSAB1) copy number resulting in elevated BST level--was common in healthy individuals (5.6% [n = 7 of 125]) and controls with nonatopic disease (5.3% [n = 21 of 398]). H[alpha]T was associated with grade IV venom anaphylaxis (relative risk = 2.0; P < .05) and more prevalent in both idiopathic anaphylaxis (n = 8 of 47; [17%; P = .006]) and SM (n = 10 of 82 [12.2%; P = .03]) relative to the controls. Among patients with SM, concomitant H[alpha]T was associated with increased risk for systemic anaphylaxis (relative risk = 9.5; P = .007). In vitro, protease-activated receptor-2-dependent vascular permeability was induced by pooled mature tryptases but not [alpha]- or [beta]-tryptase homotetramers. Conclusions: Risk for severe anaphylaxis in humans is associated with inherited differences in [alpha]-tryptase-encoding copies at TPSAB1.

62. Poškodbe drevja zaradi abiotskih naravnih motenj na bukovih rastiščih v Sloveniji s poudarkom na snegolomihBlanka Klinar, Matija Klopčič, Andrej Bončina, 2020, original scientific article Abstract: Raziskovali smo poškodovanost drevja zaradi snega v pretežno mešanih gozdnih sestojih na bukovih rastiščih v Sloveniji. V analizo smo vključili 22.609 oddelkov s prevladujočimi bukovimi rastišči, v katerih je bil delež bukve vsaj 10 % lesne zaloge sestojev. Delež iglavcev v sanitarnem poseku je bil večji pri snegolomih in vetrolomih, pri žledolomih sta bila deleža listavcev in iglavcev skoraj enaka. V bukovih gozdovih je zaradi snega najbolj poškodovano drevje v mlajših in srednjedobnih razvojnih fazah debelin 20%40 cm. Na podvzorcu 363 oddelkov, za katere smo pridobili podatke o lastnostih snežne odeje, smo z binarno logistično regresijo izdelali model verjetnosti pojava snegoloma. V model smo vključili spremenljivke količine snega v spomladanskih mesecih, fitoregijo, skalnatost, naklon terena in matično podlago. Najpomembnejša spremenljivka je bila količina snega v spomladanskih mesecih. Razlog za relativno visok sanitarni posek v bukovih gozdovih je povečan delež smreke v gozdnih sestojih, bukev je veliko manj dovzetna za poškodbe zaradi snega kot smreka. Za povečanje odpornosti sestojev predlagamo pogostejša klasična redčenja nižjih jakosti ali uvedbo situacijskih redčenj v sestojih mlajših in srednjedobnih sestojih.

64. Heat shock protein 27 as a predictor of prognosis in patients admitted to hospital with acute COPD exacerbationMatthias Zimmermann, Denise Traxler, Christine Bekos, Elisabeth Simader, Thomas Mueller, Alexandra Graf, Mitja Lainščak, Robert Marčun, Mitja Košnik, Matjaž Fležar, Aleš Rozman, Peter Korošec, 2020, original scientific article Abstract: Episodes of acute exacerbations are major drivers of hospitalisation and death from COPD. To date, there are no objective biomarkers of disease activity or biomarkers to predict patient outcome. In this study, 211 patients hospitalised for an acute exacerbation of COPD have been included. At the time of admission,routine blood tests have been performed including complete blood count, C-reactive protein, cardiac troponin T and NT-proBNP. Heat shock protein 27 (HSP27) serum concentrations were determined at time of admission, discharge and 180 days after discharge by ELISA. We were able to demonstrate significantly increased HSP27 serum concentrations in COPD patients at time of admission to hospital as compared to HSP27 concentrations obtained 180 days after discharge. In univariable Cox regression analyses, a HSP27 serum concentration >/= 3098 pg/mL determined at admission was a predictor of all-cause mortality at 90 days, 180 days, 1 year and 3 years. In multivariable analyses, an increased HSP27 serum concentration at admission retained its prognostic ability with respect to all-cause mortality for up to 1year follow-up. However, an increased HSP27 serum concentration at admission was not an independent predictor of long-term all-cause mortality at 3 years. Elevated serum HSP27 concentrations significantly predicted short-term mortality in patients admitted to hospital with acute exacerbation of COPD and could help to improve outcomes by identifying high-risk patients.

69. Robinija (Robinia pseudoacacia L.) v Beli krajini: razširjenost, priraščanje, pomlajevanje in upravljanjeBlaž Bahor, Matija Klopčič, 2019, original scientific article Abstract: Raziskovali smo razširjenost, priraščanje in pomlajevanje robinije v Beli krajini. Uporabili smo podatke Zavoda za gozdove Slovenije, del podatkov o pomlajevanju smo dodatno posneli. S podatki o gozdnih sestojih smo izračunali delež robinije v lesni zalogi in izdelali karto razširjenosti robinije ter karto površin, pomlajenih z robinijo. Debelinski in volumenski prirastek robinij smo izračunali s pomočjo podatkov s stalnih vzorčnih ploskev ter ju primerjali s prirastki drugih drevesnih vrst. S terensko pridobljenimi podatki smo analizirali pomladek na naključno izbranih stalnih vzorčnih ploskvah. Ugotovili smo, da se robinija pojavlja na 6,6 % gozdne površine, obilneje ob gozdnih robovih zunaj strnjenih gozdnih kompleksov. Lesna zaloga robinije sestavlja 3,5 % celotne lesne zaloge gozdov. Debelinski in volumenski prirastek robinije je višji od prirastka večine drevesnih vrst, s katerimi se najpogosteje pojavlja v sestojih. V prihodnosti je pričakovati nadaljnje širjenje robinije, zato jo je treba ustrezno upoštevati pri gospodarjenju z gozdovi.

70. Upravljanje velikih zveri v SlovenijiMatej Bartol, Matija Stergar, 2019, professional article Abstract: Slovenija ima bogate izkušnje s trajnostnim upravljanjem in varstvom populacij velikih zveri, zato marsikje v svetu velja za zgled na področju upravljanja populacij medveda, volka in risa. V preteklosti sta bili pri nas populaciji volka in medveda že na robu izumrtja, ris pa je bil celo iztrebljen. Zdaj ris ponovno poseljuje slovenske gozdove, populaciji medveda in volka pa se v zadnjem desetletju (pre)hitro krepita in že dolgo nista bili v tako ugodnem stanju. Medveda in volka danes pri nas še najbolj ogroža razhajanje mnenj v družbi % na eni strani zagovorniki popolne zaščite vsakega osebka, na drugi pa zagovorniki (vsaj lokalnega) iztrebljenja zveri. To zelo ovira strokovno upravljanje populacij, k nastanku takšnega stanja pa je zagotovo svoj delež prispevala zastarela evropska naravovarstvena zakonodaja. Zato bi moral biti glavni izziv upravljavcev posodobitev evropske zakonodaje, s pomočjo katere bi bilo mogoče pri ljudeh, ki živijo na območju prisotnosti velikih zveri, ohraniti določeno raven strpnosti do zveri ter uravnavati številčnost velikih zveri v mejah, ki še omogočajo ugodno stanje populacij, obenem pa so sprejemljive tudi za ljudi, ki z velikimi zvermi sobivajo.
