In vitro interactions between Eutypella parasitica and some frequently isolated fungi from the wood of the dead branches of young Sycamore Maple (Acer pseudoplatanus)
Ana Brglez, Barbara Piškur, Nikica Ogris, 2020, izvirni znanstveni članek

Povzetek: The ten most frequently isolated fungi from the wood of the dead branches of Acer pseudoplatanus L. were tested in dual cultures to evaluate their in vitro antagonistic activity against Eutypella parasitica R.W. Davidson and R.C. Lorenz, the causative agent of a destructive disease of maples in Europe and North America. The tested fungi, treated also as challenge isolates, were Diaporthe sp., Eutypa sp., Eu. maura, E. parasitica, Fusarium avenaceum, Neocucurbitaria acerina, Neonectria sp., Peniophora incarnata, Petrakia irregularis, and Phomopsis pustulata. The antagonistic ability of each challenge isolate was evaluated by calculating an index of antagonism (AI) based on the interaction type in the dual cultures. The results of competition between the fungal isolates were quantified after re-isolations from the interaction zone (s). The dual cultures revealed two main types of competitive interactions: Deadlock, consisting of mutual inhibition after mycelial contact or at a distance, and replacement, reflecting in the inhibition of E. parasitica, followed by partial overgrowth by the replacing fungus. Statistical analysis showed significant differences in average AI and s of challenge isolates between different dual culture assays. Based on the results of the antagonism index, Eutypa sp., Eu. maura, Neonectria sp., and P. incarnata had the highest inhibitory effect on E. parasitica growth and were recognized as the most promising candidates for further biocontrol studies of E. parasitica. The mycelium of E. parasitica at the interaction zones remained mostly viable, except in dual cultures with Eutypa sp., F. avenaceum, and Neonectria sp., where re-isolations did not yield any colony of the E. parasitica isolate. Based on the results, we assume that E. parasitica is a weak competitor, which invests less energy in direct mycelial competition. We discuss the potential of the observed antagonists as a possible biocontrol of Eutypella canker of maple. Nevertheless, additional experiments should be performed for a solid conclusion about competitive ability of E. parasitica and usefulness of antagonists as biocontrol.

Transcription factors gene expression in chronic rhinosinusitis with and without nasal polyps
Tanja Soklič, Matija Rijavec, Mira Šilar, Ana Koren, Izidor Kern, Irena Hočevar-Boltežar, Peter Korošec, 2019, izvirni znanstveni članek

Povzetek: Background. Chronic rhinosinusitis (CRS) current therapeutic approaches still fail in some patients with severe persistent symptoms and recurrences after surgery. We aimed to evaluate the master transcription factors gene expression levels of T cell subtypes in chronic rhinosinusitis with nasal polyps (CRSwNP) and chronic rhinosinusitis without nasal polyps (CRSsNP) that could represent new, up-stream targets for topical DNAzyme treatment. Patients and methods. Twenty-two newly diagnosed CRS patients (14 CRSwNP and 8 CRSsNP) were prospectively biopsied and examined histopathologically. Gene expression levels of T-box transcription factor (T-bet, TBX21), GATA binding protein 3 (GATA3), Retinoic acid-related orphan receptor C (RORC) and Forkhead box P3 (FOXP3) were analyzed by real-time quantitative polymerase chain reaction (RT-qPCR). Results. Eosinophilic CRSwNP was characterized by higher level of GATA3 gene expression compared to noneosinophilic CRSwNP, whereas there was no difference in T-bet, RORC and FOXP3 between eosinophilic and noneosinophilic CRSwNP. In CRSsNP, we found simultaneous upregulation of T-bet, GATA3 and RORC gene expression levels in comparison to CRSwNP; meanwhile, there was no difference in FOXP3 gene expression between CRSwNP and CRSsNP. Conclusions. In eosinophilic CRSwNP, we confirmed the type 2 inflammation by elevated GATA3 gene expression level. In CRSsNP, we unexpectedly found simultaneous upregulation of T-bet and GATA3 that is currently unexplained; however, it might originate from activated CD8+ cells, abundant in nasal mucosa of CRSsNP patients. The elevated RORC in CRSsNP could be part of homeostatic nasal immune response that might be better preserved in CRSsNP patients compared to CRSwNP patients. Further data on transcription factors expression rates in CRS phenotypes are needed.

The Chronic Urticaria Registry (CURE) : rationale, methods, and initial implementation
Karsten Weller, Ana M. Giménez-Arnau, Clive Grattan, Riccardo Asero, Pascale Mathelier-Fusade, Mojca Bizjak, Michael Hanna, Marcus Maurer, 2020, kratki znanstveni prispevek

Povzetek: Background: Chronic urticaria (CU) is a common disease, characterized by the recurrent appearance of wheals, angioedema, or both for more than 6 weeks. Its underlying biology is not well understood, and many patients do not obtain sufficient relief from recommended treatments. Patient registries are rapidly growing as a form of research, because they can provide powerful, data-driven insights about the epidemiology of diseases, real-world effectiveness of treatments, rare patient types, safety monitoring, healthcare costs, and opportunities for quality improvement of healthcare delivery. Objectives: The Chronic Urticaria Registry (CURE) has been designed to improve the scientific understanding, clinical treatment, and healthcare planning of chronic urticaria patients. This report describes the rationale, methods, and initial implementation of this registry. Methods: CURE is an ongoing, prospective, international, multicenter, observational, voluntary registry of patients with CU. Participation in CURE is open to any physician treating CU patients, regardless of location, medical specialty, or type of practice setting. CURE aims to collect data on all CU patients, with no intentional selection or exclusion criteria. It collects baseline and follow-up data on the patient's demographics, history, symptoms, trigger and risk factors, therapies, and healthcare utilization. Results: CURE is a landmark achievement of the global urticaria medical community. As of 26 February 2020, 39 centers around the world have joined the registry and 35 have entered baseline data on a total of 2946 patients. Publications of this data will be forthcoming soon. Conclusions: CURE is eagerly seeking the participation of more physicians and the support of more governmental, charitable, and commercial sponsors from around the world. Here, in this paper, we invite other physicians to join this unique project to improve the lives of patients with CU.

Poznavanje dejavnikov tveganja za nastanek raka med slovenskimi najstniki
Ana Košir, Enej Hadžić, Jasna But-Hadžić, 2020, izvirni znanstveni članek

Povzetek: Uvod: Glede na trenutne trende lahko pričakujemo, da naj bi eden od dveh fantov in ena od treh deklet današnjih najstnikov do 75. leta starosti zboleli za rakom. Po podatkih državnega programa za obvladovanje raka bi lahko kar 40 % rakavih bolezni preprečili z zdravim načinom življenja in izogibanjem dejavnikom tveganja. Za to bi morali najstniki dobro poznati dejavnike tveganja, da bi v prihodnosti zmanjšali pojavnost te bolezni. Namen: Glavni namen raziskave je bil ugotoviti, kako dobro najstniki poznajo dejavnike tveganja nastanka raka, ter preveriti, ali je razlika v znanju med spoloma ter med različno starimi najstniki. Metode dela: V raziskavo smo vključili 185 najstnikov, starih med 12 in 15 let (54 % fantov, 46 % deklet), ki so izpolnili mednarodni vprašalnik o poznavanju dejavnikov tveganja nastanka raka. Vprašalnike smo nato prenesli v elektronsko obliko s pomočjo spletnega orodja 1KA, ki nam je omogočil pripravo in tudi delno obdelavo rezultatov. Rezultati: Najstniki na splošno dobro poznajo dejavnike tveganja za nastanek raka, saj so med najpogostejšimi 10 dejavniki pravilno opredelili 6,7 dejavnika. Fanti so imeli statistično pomembno (p = 0,026) nižjo povprečno oceno 6,44 kot dekleta, ki so imela oceno 6,95, pri čemer sta razliki nastali v oceni kajenja in telesne mase. V obeh primerih je več deklet kot fantov pravilno opredelilo ta dejavnik tveganja. 58 % učencev skrbi, da bodo zboleli za rakom, pri tem pa je med spoloma bistvena razlika, saj to skrb izraža 74 % deklet in le 44% fantov (p < 0,001). Med najpomembnejšimi dejavniki tveganja slovenski najstniki na prvem mestu navajajo kajenje (55 %), na drugem alkohol (24 %), na tretjem sevanje (14 %) in na četrtem nezdravo prehrano (14 %). Med učenci se jih 83 % strinja, da nekatera živila povečajo možnost nastanka raka. Pri vprašanju o številu potrebnih dnevnih porcij sadja in zelenjave je povprečen odgovor 3,5 porcije od priporočenih 5. Večina učencev (69 %) meni, da je rdeče meso dejavnik tveganja za nastanek raka, samo polovica pa ve, da je treba dnevno zaužiti manj kot 5 g soli. Da je vzdrževanje zdrave telesne mase eden najpomembnejših načinov preprečitve raka, se strinja 81 % učencev, 85 % pa jih meni, da je telesna dejavnost povezana s preprečevanjem nastanka raka. 87 % učencev dobro pozna nevarnost sončenja, prav tako pa dobro opredeljujejo alkohol kot dejavnik tveganja, čeprav jih 74 % ni prepričanih, ali imajo vse alkoholne pijače enak učinek. Zaključki: Raziskava kaže na zelo dobro poznavanje dejavnikov tveganja za nastanek raka med slovenskimi najstniki. Zato menimo, da lahko današnja mladina v primerjavi s prejšnjimi generacijami doseže manjšo obolevnost za rakom ob nadaljnjem širjenju informacij o teh dejavnikih, ki temeljijo na dokazih.
