311. Nrf2-interacting nutrients and COVID-19 : time for research to develop adaptation strategiesJean Bousquet, Jean-Paul Cristol, Wienczyslawa Czarlewski, Josep M. Antò i Boquè, Adrian Martineau, Tari Haahtela, Susana C. Fonseca, Guido Iaccarino, Hubert Blain, Alessandro Fiocchi, Nisera Bajrović, Natalija Edelbaher, Maja Jošt, Peter Kopač, Anja Koren, Mitja Košnik, Karmen Kramer Vrščaj, Samo Kreft, Nika Lalek, Bojan Madjar, Tonka Poplas-Susič, Irma Rozman Sinur, Tanja Soklič, Katja Triller Vadnal, Nadja Triller, Jure Urbančič, Mihaela Zidarn, 2020, review article Abstract: There are large between- and within-country variations in COVID-19 death rates. Some very low death rate settings such as Eastern Asia, Central Europe, the Balkans and Africa have a common feature of eating large quantities of fermented foods whose intake is associated with the activation of the Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) anti-oxidant transcription factor. There are many Nrf2-interacting nutrients (berberine, curcumin, epigallocatechin gallate, genistein, quercetin, resveratrol, sulforaphane) that all act similarly to reduce insulin resistance, endothelial damage, lung injury and cytokine storm. They also act on the same mechanisms (mTOR: Mammalian target of rapamycin, PPAR[gamma]:Peroxisome proliferator-activated receptor, NF[kappa]B: Nuclear factor kappa B, ERK: Extracellular signal-regulated kinases and eIF2[alpha]:Elongation initiation factor 2[alpha]). They may as a result be important in mitigating the severity of COVID-19, acting through the endoplasmic reticulum stress or ACE-Angiotensin-II-AT1R axis (AT1R) pathway. Many Nrf2-interacting nutrients are also interacting with TRPA1 and/or TRPV1. Interestingly, geographical areas with very low COVID-19 mortality are those with the lowest prevalence of obesity (Sub-Saharan Africa and Asia). It is tempting to propose that Nrf2-interacting foods and nutrients can re-balance insulin resistance and have a significant effect on COVID-19 severity. It is therefore possible that the intake of these foods may restore an optimal natural balance for the Nrf2 pathway and may be of interest in the mitigation of COVID-19 severity.

312. The effect of olive fruit fly Bactrocera oleae (Rossi) infestation on certain chemical parameters of produced olive oilsVasilij Valenčič, Bojan Butinar, Maja Podgornik, Milena Bučar-Miklavčič, 2021, original scientific article Abstract: Olives affected by active and damaging infestation (olive fruit fly Bactrocera oleae (Rossi)) were assayed for their chemical composition. Biophenols were determined by HPLC, sterols, triterpenic dialcohols, and fatty acids by gas chromatography analysis. The acquired data were statistically analyzed. Oils produced from "Istrska belica" fruit affected by active infestation compared to the oils made from fruit affected by damaging infestation showed higher amounts of total oleuropein biofenols (377.3 versus (vs.) 106.6 mg/kg), total biophenols (755 vs. 377 mg/kg), lignans (85.3 vs. 32.9mg/kg), the dialdehydic formof decarboxymethyl oleuropein aglycone (DMO-AgldA) (148.3 vs. 49.0 mg/kg), its oxidized form (DMO-Agl-dA)ox (35.2 vs. 8.5 mg/kg), the dialdehydic form of oleuropein aglycone (O-Agl-dA) (61.1 vs. 8.0 mg/kg), the dialdehydic form of ligstroside aglycone (L-Agl-dA) (63.5 vs. 28.0 mg/kg), the aldehydic form of oleuropein aglycone (O-Agl-A) (40.6 vs. 8.4 mg/kg), and lower amounts of tyrosol (Tyr) (6.0 vs. 13. 9 mg/kg) and the aldehydic form of ligstroside aglycone (L-Agl-A) (13.8 vs. 40.3 mg/kg). Higher values of stigmasterol (2.99%) and lower values of campesterol (2.25%) were determined in oils affected by damaging infestation; an increase in triterpenic dialcohols was also observed (3.04% for damaging and 1.62% for active infestation). Oils affected by damaging infestation, compared to active infestation, showed lower amounts of oleic acid (73.89 vs. 75.15%) and higher amounts of myristic (0.013 vs. 0.011%), linoleic (7.27 vs. 6.48%), and linolenic (0.74 vs. 0.61%) acids.

313. Elektrokemoterapija : učinki na žilje tumorjaGregor Serša, Maja Čemažar, Marko Snoj, 2008, professional article Abstract: Terapevtska učinkovitost zdravljenj, ki delujejo na žilje tumorja, je sedaj splošno priznana. Odkrivajo se vedno nova zdravila in pristopi, ki ciljajo žilje tumorja, zato jih imenujemo žilno ciljano zdravljenje (vascular targeted therapies). Poznamo dve vrsti tega zdravljenja, in sicer antiangiogeno (anti-angiogenic therapies) in žilno razdiralno (vascular-disrupting therapies). Ločita se po fizioloških tarčah, primernosti za zdravljenje glede na obseg bolezni in režimu zdravljenja. Zadnja odkritja kažejo, da ima elektrokemoterapija poleg neposrednega citotoksičnega delovanja tudi žilno razdiralni učinek, ker na endotelne celice tumorskega žilja deluje citotoksično. Zaradi odmiranja teh celic prihaja do trajnih ustavitev pretoka krvi in do ishemičnega propada tumorskih celic v poškodovanih delih tumorja. Zaradi žilno razdiralnega učinka je elektrokemoterapija učinkovita tudi pri zdravljenju krvavečih tumorskih lezij, kar se kaže v takojšnji ustavitvi krvavitve in v poznejšem zmanjšanju tumorske lezije. Raziskave je podprla ARRS.

314. Temeljni pojmi in predlagano izrazoslovje v paliativni oskrbiMaja Ebert Moltara, Marjana Bernot, Jernej Benedik, Andrej Žist, Nena Golob, Stanislav Malačič, Maja Kolšek-Šušteršič, Maja Ivanetič Pantar, Blaž Koritnik, Anamarija Meglič, Nevenka Krčevski-Škvarč, 2020, professional monograph Abstract: Paliativna oskrba je v slovenskem prostoru mlada stroka. Z njenim razvojem so se začeli uporabljati številni izrazi, ki so včasih nejasno in nenatančno opredeljeni. Posledica tega je, tako med strokovnjaki kot na splošno v družbi, njeno neustrezno razumevanje. občasno zato prihaja do nesporazumov in posledično tudi do strokovnih napak. Namen izvajanja paliativne oskrbe je zagotoviti čim boljšo kakovost življenja bolnikom z napredujočimi neozdravljivimi boleznimi ter nuditi podporo njihovim bližnjim, v času bolnikove bolezni in po smrti. V paliativni oskrbi zdravstveno osebje veliko bolj kot sicer posveča pozornost celostni obravnavi posameznega človeka, kot osebo z individualnimi telesnimi, psihološkimi, socialnimi in duhovnimi potrebami. To je dinamičen proces, saj se moramo ves čas prilagajati trenutnim potrebam bolnika in njegovih bližnjih ter z aktivnim načrtovanjem učinkovito preprečevati nove in nepotrebne zaplete. Zgodnja paliativna oskrba se v začetku obravnave bolnika z neozdravljivo boleznijo prepleta s specifičnim zdravljenjem. Kasneje, z napredovanjem bolezni, obravnava prehaja v obdobje pozne paliativne oskrbe in obdobje oskrbe umirajočega. Po sodobnih smernicah se paliativna oskrba izvaja celostno, neprekinjeno in integrirano v ostale zdravstvene stroke. Cilj paliativne oskrbe je sledenje vrednotam posameznika in ohranjanje dostojanstva življenja. V prispevku smo zbrali najpogosteje uporabljene izraze s področja paliativne oskrbe. Na podlagi mednarodnih priporočil, lokalnih značilnosti in nacionalnih izkušenj smo jih skušali čim bolj jasno opredeliti za naš prostor. Natančno opredeljeni pojmi paliativne oskrbe in njihova dosledna uporaba bodo vodili k boljšemu medsebojnemu razumevanju strokovnjakov in uporabnikov paliativne oskrbe ter k njenemu kakovostnejšemu izvajanju.

316. Borova ogorčica, Bursaphelenchus xylophilus (Steiner & Buhrer, 1934) Nickle, 1970 - nova nevarnost za slovenske gozdove?Maja Jurc, Gregor Urek, Saša Širca, Vid Mikulič, Branko Glavan, 2003, review article Abstract: V prispevku obravnavamo borovo ogorčico (Bursaphelenchus xylophilus), ki je v Evropi (tudi v Sloveniji) uvrščena na karantensko listo A1. Vrsta je izredno napadalna, povzroča hitro propadanje iglavcev - predvsem vrst rodu Pinus, redko Picea, Abies in Larix. Prikazan je njen areal, ekološke zahteve, gostitelji, bionomija ter simptomi napada na borih. V okviru bionomije borove ogorčice so posebej predstavljeni njeni potrjeni vektorji (Insecta: Cerambycidae - rod Monochamus) in tudi njeni potencialni vektorji (Insecta: Curculionidae - rod Pissodes in Scolytidae). Podajamo razširjenost potencialnih gostiteljskih rastlin borove ogorčice pri nas, podnebne razmere ter kritične točke za vnos in širjenje škodljivca. Ocenjujemo stopnjo fitosanitarnega tveganja pojava borove ogorčice v Sloveniji.

317. Živeti s podlubniki : trajnostno upravljanje gozdov v EvropiMaja Jurc, 2020, review article Abstract: Gozdovi pokrivajo več kot 31 odstotkov kopnega, evropski gozdovi, skupaj z ruskimi, pa 44,3 odstotka površine Evrazije. Že stoletja gozdovi zagotavljajo človeštvu bistvene ekosistemske storitve in ekonomske dobičke. Vrednosti gozdov vedno bolj ogrožajo ekstremni dogodki, kot so suša, orkanski veter ter podlubniki. Prav tako so nekatere prejšnje prakse upravljanja z gozdovi pomembno povečale njihovo ranljivost. Tako so v minulem stoletju zaradi relativno hitre rasti in dobrih lastnosti lesa sadili navadno smreko (Picea abies) v monokulturah v nižinskih območjih, zunaj njenega naravnega areala. Nastala so velika območja tako imenovanih sekundarnih gozdov, v katerih pešajo zdravje, vitalnost in odpornost smreke in njeni sestoji so izredno občutljivi za številne motnje, med katerimi so najpomembnejši smrekovi podlubniki (predvsem Ips typographus). Namen prispevka je pomoč nacionalnim oblikovalcem politik razumeti zapletene vloge, ki jih imajo podlubniki v gozdovih, in predstaviti najpomembnejše znanstvene podlage za gozdno politiko in različne možnosti upravljanja s podlubniki v evropskih gozdovih.

318. Prevalence of and factors associated with healthcare-associated infections in Slovenian acute care hospitals : results of the third national surveyIrena Klavs, Mojca Serdt, Aleš Korošec, Tatjana Lejko-Zupanc, Blaž Pečavar, 2019, original scientific article Abstract: Introduction. In the third Slovenian national healthcare-associated infections (HAIs) prevalence survey, conducted within the European point prevalence survey of HAIs and antimicrobial use in acute care hospitals, we estimated the prevalence of all types of HAIs and identified factors associated with them. Methods. Patients were enrolled into a one-day cross-sectional study in November 2017. Descriptive analyses were performed to describe the characteristics of patients, their exposure to invasive procedures and the prevalence of different types of HAIs. Univariate and multivariate analyses of association of having at least one HAI with possible risk factors were performed to identify risk factors. Results. Among 5,743 patients, 4.4% had at least one HAI and an additional 2.2% were still treated for HAIs on the day of the survey, with a prevalence of HAIs of 6.6%. The prevalence of pneumoniae was the highest (1.8%), followed by surgical site infections (1.5%) and urinary tract infections (1.2%). Prevalence of blood stream infections was 0.3%. In intensive care units (ICUs), the prevalence of patients with at least one HAI was 30.6%. Factors associated with HAIs included central vascular catheter (adjusted odds ratio [aOR] 4.1; 95% confidence intervals [CI]: 3.1–5.4), peripheral vascular catheter (aOR 3.0; 95% CI: 2.3–3.9), urinary catheter (aOR 1.8; 95% CI: 1.4–2.3). Conclusions. The prevalence of HAIs in Slovenian acute care hospitals in 2017 was substantial, especially in ICUs. HAIs prevention and control is an important public health priority. National surveillance of HAIs in ICUs should be developed to support evidence-based prevention and control.

319. Cabbage and fermented vegetables : from death rate heterogeneity in countries to candidates for mitigation strategies of severe COVID-19Jean Bousquet, Josep M. Antò i Boquè, Wienczyslawa Czarlewski, Tari Haahtela, Susana C. Fonseca, Guido Laccarino, Hubert Blain, Alain Vidal, Aziz Sheikh, Cezmi A. Akdis, Torsten Zuberbier, Samo Kreft, Klemen Jenko, Maja Jošt, Peter Kopač, Mitja Košnik, Karmen Kramer Vrščaj, Bojan Madjar, Davor Plavec, Tanja Soklič, Jure Urbančič, Mihaela Zidarn, 2020, original scientific article Abstract: Large differences in COVID-19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage were associated with low death rates in European countries. SARS-CoV-2 binds to its receptor, the angiotensin converting enzyme 2 (ACE2). As a result of SARS-Cov-2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT1R) axis associated with oxidative stress. This leads to insulin resistanceas well as lung and endothelial damage, two severe outcomes of COVID-19. The nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is the most potent antioxidant in humans and can block the AT1R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are given: Kimchi in Korea, westernized foods and the slum paradox. It is proposed that fermented cabbage is a proof-of-concept of dietary manipulations that may enhance Nrf2-associated antioxidant effects helpful in mitigating COVID-19 severity.
