71. First report of Diplodia fraxini and Diplodia subglobosa causing canker and dieback of Fraxinus excelsior in SloveniaBenedetto Teodoro Linaldeddu, Carlo Bregant, Lucio Montecchio, Ana Brglez, Barbara Piškur, Nikica Ogris, 2022, short scientific article Abstract: Over the last decades the vitality and productivity of European ash trees in Slovenia has been seriously impacted by the onset of canker and dieback disease symptoms on young and old trees, primarily identified as ash dieback caused by Hymenoscyphus fraxineus. Given the limited information available about the aetiology of this emerging disease, a study was carried out to isolate, identify and characterize the fungal species involved in the observed ash symptoms. Field surveys were conducted in five forest sites where 50 symptomatic branch samples were collected. All samples were inspected and used for fungal isolation. Based on morphology, colony appearance and DNA sequence data of the internal transcribed spacer region (ITS), 125 fungal colonies belonging to five species were isolated and identified. Only a few symptomatic ash samples yielded colonies of H. fraxineus, whereas Botryosphaeriaceae species were isolated with a high frequency, with Diplodia fraxini as the dominant species. A pathogenicity test proved that all isolated species were pathogenic on European ash, causing bark lesions and wood discoloration. All Botryosphaeriaceae species isolated in this study are reported for the first time on European ash in Slovenia.

74. Case report : congenital extrahepatic portocaval shunt presenting as pulmonary arterial hypertension in a pregnant patientMatevž Harlander, Maja Badovinac, Frosina Markoska, Barbara Salobir, Tomaž Štupnik, Marija Dolenšek, Izidor Kern, Vojka Gorjup, Nazzareno Galiè, 2022, short scientific article Abstract: Congenital extrahepatic portocaval shunt (CEPS) is a rare condition in which a rare congenital vascular anomaly of the portal system is present. CEPS may manifest as pulmonary arterial hypertension (PAH). When diagnosed and treated early, PAH can be reversible. We report a case of a previously asymptomatic woman, who manifested with severe pulmonary hypertension during pregnancy and was consequently diagnosed with CEPS. After unsuccessful medical treatment, urgent lung transplantation was done.

77. A meta-analysis of global fungal distribution reveals climate-driven patternsTomáš Větrovský, Petr Kohout, Martin Kopecky, Antonin Machac, Matěj Man, Barbara Doreen Bahnmann, Vendula Brabcová, Jinlyung Choi, Lenka Mészárosová, Zander Rainier Human, Clémentine Lepinay, Rubén López-Mondéjar, Tijana Martinović, 2019, original scientific article Abstract: The evolutionary and environmental factors that shape fungal biogeography are incompletely understood. Here, we assemble a large dataset consisting of previously generated mycobiome data linked to specific geographical locations across the world. We use this dataset to describe the distribution of fungal taxa and to look for correlations with different environmental factors such as climate, soil and vegetation variables. Our meta-study identifies climate as an important driver of different aspects of fungal biogeography, including the global distribution of common fungi as well as the composition and diversity of fungal communities. In our analysis, fungal diversity is concentrated at high latitudes, in contrast with the opposite pattern previously shown for plants and other organisms. Mycorrhizal fungi appear to have narrower climatic tolerances than pathogenic fungi. We speculate that climate change could affect ecosystem functioning because of the narrow climatic tolerances of key fungal taxa.

78. GlobalFungi, a global database of fungal occurrences from high-throughput-sequencing metabarcoding studiesTomáš Větrovský, Daniel Morais, Petr Kohout, Clémentine Lepinay, Camelia Algora, Sandra Awokunle Hollá, Barbara Doreen Bahnmann, Květa Bílohnědá, Vendula Brabcová, Federica DʹAlò, Tijana Martinović, 2020, original scientific article Abstract: Fungi are key players in vital ecosystem services, spanning carbon cycling, decomposition, symbiotic associations with cultivated and wild plants and pathogenicity. The high importance of fungi in ecosystem processes contrasts with the incompleteness of our understanding of the patterns of fungal biogeography and the environmental factors that drive those patterns. To reduce this gap of knowledge, we collected and validated data published on the composition of soil fungal communities in terrestrial environments including soil and plant-associated habitats and made them publicly accessible through a user interface at https://globalfungi.com. The GlobalFungi database contains over 600 million observations of fungal sequences across >17 000 samples with geographical locations and additional metadata contained in 178 original studies with millions of unique nucleotide sequences (sequence variants) of the fungal internal transcribed spacers (ITS) 1 and 2 representing fungal species and genera. The study represents the most comprehensive atlas of global fungal distribution, and it is framed in such a way that third-party data addition is possible.

79. Predsimptomatsko genetsko testiranje za dedni sindrom raka dojk in/ali jajčnikovBarbara Babuder, Simona Hotujec, Ana Blatnik, Ksenija Strojnik, Marta Banjac, Srdjan Novaković, Mateja Krajc, 2021, original scientific article Abstract: Izhodišče: Kaskadno testiranje je testiranje svojcev prvega dokazanega nosilca patogene različice/verjetno patogene različice (PR/VPR) določenega gena v družini. Uspešnost preventive rakavih bolezni v družini, v kateri je ugotovljena PR/VPR, je odvisna od identifikacije tistih krvnih sorodnikov, ki so prav tako nosilci družinske genetske okvare, pa sami še niso zboleli. Število krvnih sorodnikov iz družin z dednim sindromom za raka dojk in/ali jajčnikov (HBOC), ki se v sklopu obravnave na Onkološkem inštitutu Ljubljana (OIL) odločijo za predsimptomatsko svetovanje in testiranje po novoodkriti PR/VPR v družini, je trenutno neznano.
Namen: Namen raziskave je bil ugotoviti število krvnih sorodnikov, ki so se odločili za predsimptomatsko testiranje, ko je bila v družini dokazana PR/VPR v genu BRCA1 in/ali BRCA2, in analizirati njihove značilnosti.
Metode: Analizirali smo podatke, ki smo jih pridobili iz podatkovne zbirke Oddelka za onkološko klinično genetiko OIL med letoma 1999 in 2020, o testiranih in njihovih družinskih članih. Uporabili smo deskriptivne statistične metode.
Rezultati: Med 5158 napotenimi družinami s sumom na HBOC smo odkrili 785 BRCA1 in BRCA2 pozitivnih, kar pomeni 15,2 %. Od vseh 785 pozitivnih družin se pri 27 % (212/785) družin za genetsko svetovanje še ni odločil nihče od svojcev. V družinah, kjer so se svojci odločili za posvet (573 družin), se jih je 79 % oglasilo v prvih 12 mesecih od razkritja pozitivnega rezultata prvemu testiranemu. V teh 573 družinah se je skupno 1731 oseb odločilo za predsimptomatsko testiranje, od tega je bilo 80,3 % žensk. Povprečno število krvnih sorodnikov, ki so se med letoma 1999 in 2020 odločili za predsimptomatsko svetovanje in testiranje, je dva (2,21) na družino. Če odštejemo družine, v katerih se ni javil nihče od svojcev, pa so se javili povprečno trije (3,02) svojci na družino, torej so poleg nosilca družine na posvet prišli vsaj še trije.
Zaključek: Kaskadno testiranje je uspešen način ugotavljanja nosilcev PR/VPR v družini in v populaciji. Trenutno je edini dokazano uspešen način, s katerim lahko zdravim, bolj ogroženim posameznikom omogočimo preventivne ukrepe preprečevanja in zgodnjega odkrivanja raka, s čimer dokazano podaljšujemo življenja. Možnost za odločitev o preventivnih ukrepih bi morali tako imeti vsi krvni sorodniki ob pozitivnem rezultatu prvega testiranega. Treba bo raziskati, zakaj se pri slabi tretjini pozitivnih družin ni javil noben družinski član in kako lahko še izboljšamo klinične poti, da bi povečali odziv svojcev.
