Worldwide perspectives on venom allergy
Peter Korošec, Thilo Jakob, Harfi Harb, Robert Heddle, Sarah Karabus, Ricardo de Lima Zollner, Julij Šelb, Bernard Yu-Hor Thong, Fares Zaitoun, David B. K. Golden, Michael Levin, 2019

Povzetek: Venom immunotherapy is the standard of care for people with severe reactions and has been proven to reduce risk of future anaphylactic events. There is a moral imperative to ensure production, supply and worldwide availability of locally relevant, registered, standardized commercial venom extracts for diagnosis and treatment. Insects causing severe immediate allergic reactions vary by region worldwide. The most common culprits include honeybees (Apis mellifera), social wasps including yellow jackets (Vespula and Dolichovespula), paper wasps (Polistes) and hornets (Vespa), stinging ants (Solenopsis, Myrmecia, Pachycondyla, and Pogonomyrmex), and bumblebees (Bombus). Insects with importance in specific areas of the world include the Australian tick (Ixodes holocyclus), the kissing bug (Triatoma spp), horseflies (Tabanus spp), and mosquitoes (Aedes, Culex, Anopheles). Reliable access to high quality venom immunotherapy to locally relevant allergens is not available throughout the world. Many current commercially available therapeutic vaccines have deficiencies, are not suitable for, or are unavailable in vast areas of the globe. New products are required to replace products that are unstandardized or inadequate, particularly whole-body extract products. New products are required for insects in which no current treatment options exist. Venom immunotherapy should be promoted throughout the world and the provision thereof be supported by health authorities, regulatory authorities and all sectors of the health care service.

Trained facilitators' experiences with structured advance care planning conversations in oncology : an international focus group study within the ACTION trial
Marieke Zwakman, K. Pollock, Francesco Bulli, Glenys Caswell, Branka Červ, Johannes JM van Delden, Luc Deliens, Agnes van der Heide, Lea J. Jabbarian, Hana Kodba Čeh, Urška Lunder, Anja Simonič, 2019

Povzetek: Background: In oncology, health care professionals often experience conducting advance care planning (ACP) conversations as difficult and are hesitant to start them. A structured approach could help to overcome this. In the ACTION trial, a Phase III multi-center cluster-randomized clinical trial in six European countries (Belgium, Denmark, Italy, the Netherlands, Slovenia, United Kingdom), patients with advanced lung or colorectal cancer are invited to have one or two structured ACP conversations with a trained facilitator. It is unclear how trained facilitators experience conducting structured ACP conversations. This study aims to understand how facilitators experience delivering the ACTION Respecting Choices (RC) ACP conversation. Methods: A qualitative study involving focus groups with RC facilitators. Focus group interviews were recorded, transcribed, anonymized, translated into English, and thematically analysed, supported by NVivo 11. The international research team was involved in data analysis from initial coding and discussion towards final themes. Results: Seven focus groups were conducted, involving 28 of in total 39 trained facilitators, with different professional backgrounds from all participating countries. Alongside some cultural differences, six themes were identified. These reflect that most facilitators welcomed the opportunity to participate in the ACTION trial, seeing it as a means of learning new skills in an important area. The RC script was seen as supportive to ask questions, including those perceived as difficult to ask, but was also experienced as a barrier to a spontaneous conversation. Facilitators noticed that most patients were positive about their ACTION RC ACP conversation, which had prompted them to become aware of their wishes and to share these with others. The facilitators observed that it took patients substantial effort to have these conversations. In response, facilitators took responsibility for enabling patients to experience a conversation from which they could benefit. Facilitators emphasized the need for training, support and advanced communication skills to be able to work with the script. Conclusions: Facilitators experienced benefits and challenges in conducting scripted ACP conversations. They mentioned the importance of being skilled and experienced in carrying out ACP conversations in order to be able to explore the patients' preferences while staying attuned to patients' needs.

Dynamic contrast-enhanced MRI of malignant pleural mesothelioma : a comparative study of pharmacokinetic models and correlation with mRECIST criteria
Martina Vivoda Tomšič, Sotirios Bisdas, Viljem Kovač, Igor Serša, Katarina Šurlan Popović, 2019

Povzetek: BACKGROUND: Malignant pleural mesothelioma (MPM) is a rare and aggressive thoracic malignancy that is difficult to cure. Dynamic contrast-enhanced (DCE) MRI is a functional imaging technique used to analyze tumor microvascular properties and to monitor therapy response. Purpose of this study was to compare two tracer kinetic models, the extended Tofts (ET) and the adiabatic approximation tissue homogeneity model (AATH) for analysis of DCE-MRI and examine the value of the DCE parameters to predict response to chemotherapy in patients with MPM. METHOD: This prospective, longitudinal, single tertiary radiology center study was conducted between October 2013 and July 2015. Patient underwent DCE-MRI studies at three time points: prior to therapy, during and after cisplatin-based chemotherapy. The images were analyzed using ET and AATH models. In short-term follow-up, the patients were classified as having disease control or progressive disease according to modified response evaluation criteria in solid tumors (mRECIST) criteria. Receiver operating characteristic curve analysis was used to examine specificity and sensitivity of DCE parameters for predicting response to therapy. Comparison tests were used to analyze whether derived parameters are interchangeable between the two models. RESULTS: Nineteen patients form the study population. The results indicate that the derived parameters are not interchangeable between the models. Significant correlation with response to therapy was found for AATH-calculated median pre-treatment efflux rate (kep) showing sensitivity of 83% and specificity of 100% (AUC 0.9). ET-calculated maximal pre-treatment kep showed 100% sensitivity and specificity for predicting treatment response during the early phase of the therapy and reached a favorable trend to significant prognostic value post-therapy. CONCLUSION: Both models show potential in predicting response to therapy in MPM. High pre-treatment kep values suggest MPM disease control post-chemotherapy.

Lung cancer biomarker testing : perspective from Europe
Erik Thunnissen, Birgit Weynand, Dalma Udovicic-Gagula, Luka Brčić, Malgorzata Szolkowska, Paul Hofman, Silvana Smojver-Ježek, Sisko Anttila, Fiorella Calabrese, Izidor Kern, 2020

Povzetek: A questionnaire on biomarker testing previously used in central European countries was extended and distributed in Western and Central European countries to the pathologists participating at the Pulmonary Pathology Society meeting 26-28 June 2019 in Dubrovnik, Croatia. Each country was represented by one responder. For recent biomarkers the availability and reimbursement of diagnoses of molecular alterations in non-small cell lung carcinoma varies widely between different, also western European, countries. Reimbursement of such assessments varies widely between unavailability and payments by the health care system or even pharmaceutical companies. The support for testing from alternative sources, such as the pharmaceutical industry, is no doubt partly compensating for the lack of public health system support, but it is not a viable or long-term solution. Ideally, a structured access to testing and reimbursement should be the aim in order to provide patients with appropriate therapeutic options. As biomarker enabled therapies deliver a 50% better probability of outcome success, improved and unbiased reimbursement remains a major challenge for the future.

Absence of adverse effects of tiotropium/ olodaterol compared with the monocomponents on long-term heart rate and blood pressure in patients with moderate-to-very-severe COPD
Roland Buhl, Matjaž Fležar, Alberto De La Hoz, Matthias Trampisch, Ulrich Bothner, Lorcan Mcgarvey, Stefan Andreas, Peter Alter, 2020

Povzetek: Introduction: Long-acting [beta]2-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) are established maintenance bronchodilator treatments for chronic obstructive pulmonary disease (COPD) with the potential to increase heart rate (HR) and impact blood pressure (BP). While previous studies indicate that HR and BP are not negatively influenced by tiotropium or olodaterol monotherapy, the effect of tiotropium/olodaterol has not been evaluated. We report a post hoc analysis of the effect of dual bronchodilation with tiotropium/olodaterol versus monocomponents on HR and BP in patients with moderate-to-very-severe COPD included in the large TONADO© study. Methods: The TONADO© trials (1237.5 [NCT01431274] and 1237.6 [NCT01431287]) were two replicate, randomized, double-blind, parallel-group, 52-week, Phase III trials that compared tiotropium/olodaterol (5/5 [micro]g and 2.5/5 [micro]g) with tiotropium (5 [micro]g and 2.5 [micro]g) and olodaterol (5 [micro]g) in patients with moderate-to-very-severe COPD. Patients with cardiovascular comorbidities were included. Changes in HR and systolic/diastolic BP were measured before and after dosing with the study medication at each visit (baseline, Week 12, Week 24 and Week 52). Results: Overall, 3,100 patients were included in this analysis. Over 52 weeks, small changes from baseline in mean HR (<2 beats per minute [bpm]) and small changes from pre- to post-dose (<1 bpm) were evident at different time points. There was a non-significant increase from baseline in mean diastolic and systolic BP (<2 mmHg) observed over 52 weeks of treatment. The short-term (1 hour pre- to 1 hour post-dose) mean changes in systolic and diastolic BP over 52 weeks in the tiotropium/olodaterol 5/5 [micro]g group were comparable with those observed for the monocomponents at all time points. Conclusion: There were no differences in HR or BP among patients on tiotropium/olodaterol when compared with monocomponents. This supports the already demonstrated cardiovascular safety profile of tiotropium/olodaterol as long-acting maintenance bronchodilator treatment for COPD, including patients with cardiovascular comorbidities.

Sequential afatinib and osimertinib in patients with EGFR mutation-positive non-small-cell lung cancer : updated analysis of the observational GioTag study
Maximilian J Hochmair, Alessandro Morabito, Desiree Hao, Cheng-Ta Yang, Ross A Soo, James C-H Yang, Rasim Gucalp, Balazs Halmos, Lara Wang, Angela Märten, Tanja Čufer, 2019

Povzetek: Aims: Overall survival (OS) and updated time to treatment failure (TTF) analysis of patients with EGFR mutation-positive (Del19, L858R) non-small-cell lung cancer who received sequential afatinib/osimertinib in the real-world GioTag study. Patients & methods: Patients had T790M-positive disease following first-line afatinib and received osimertinib treatment (n = 203). Primary outcome was TTF. The OS analysis was exploratory. Results: Median OS was 41.3 months (90% CI: 36.8-46.3) overall and 45.7 months (90% CI: 45.3-51.5) in patients with Del19-positive tumors (n = 149); 2-year survival was 80 and 82%, respectively. Updated median TTF with afatinib and osimertinib was 28.1 months (90% CI: 26.8-30.3). Conclusion: Sequential afatinib/osimertinib was associated with encouraging OS/TTF in patients with EGFR T790M-positive non-small-cell lung cancer, especially in patients with Del19-positive tumors.

Is diet partly responsible for differences in COVID-19 death rates between and within countries? : protocol for a systematic review
Mihaela Zidarn, Jure Urbančič, Tanja Soklič, Davor Plavec, Bojan Madjar, Klemen Jenko, Samo Kreft, Maja Jošt, Peter Kopač, Anja Koren, Mitja Košnik, Tari Haahtela, Karmen Kramer Vrščaj, Giorgio Walter Canonica, Hubert Blain, Cezmi A. Akdis, Aram Anto, Tari Haahtela, Wienczyslawa Czarlewski, Guido Laccarino, Josep M. Antò i Boquè, Jean Bousquet, 2020

Povzetek: Reported COVID-19 deaths in Germany are relatively low as compared to many European countries. Among the several explanations proposed, an early and large testing of the population was put forward. Most current debates on COVID-19 focus on the differences among countries, but little attention has been given to regional differences and diet. The low-death rate European countries (e.g. Austria, Baltic States, Czech Republic, Finland, Norway, Poland, Slovakia) have used different quarantine and/or confinement times and methods and none have performed as many early tests as Germany. Among other factors that may be significant are the dietary habits. It seems that some foods largely used in these countries may reduce angiotensin-converting enzyme activity or are anti-oxidants. Among the many possible areas of research, it might be important to understand diet and angiotensin-converting enzyme-2 (ACE2) levels in populations with different COVID-19 death rates since dietary interventions may be of great benefit.

Genomic insights into the Mycobacterium kansasii complex : an update
Paulina Borówka, Tomasz Jagielski, Dominik Strapagiel, Marija Žolnir-Dovč, Jakobus van Ingen, Lian Pennings, Mikołaj Dziurzyński, Jarosław Dziadek, Anna Brzostek, Błażej Marciniak, Jakub Lach, Zofia Bakuła, 2020

Povzetek: Only very recently, has it been proposed that the hitherto existing Mycobacteriumkansasii subtypes (I–VI) should be elevated, each, to a species rank. Consequently, the former M. kansasii subtypes have been denominated as Mycobacterium kansasii (former type I), Mycobacterium persicum (II), Mycobacterium pseudokansasii (III), Mycobacterium innocens (V), and Mycobacterium attenuatum (VI). The present work extends the recently published findings by using a three-pronged computational strategy, based on the alignment fraction-average nucleotide identity, genome-to-genome distance, and core-genome phylogeny, yet essentially independent and much larger sample, and thus delivers a more refined and complete picture of the M. kansasii complex. Furthermore, five canonical taxonomic markers were used, i.e., 16S rRNA, hsp65, rpoB, and tuf genes, as well as the 16S-23S rRNA intergenic spacer region (ITS). The three major methods produced highly concordant results, corroborating the view that each M. kansasii subtype does represent a distinct species. This work not only consolidates the position of five of the currently erected species, but also provides a description of the sixth one, i.e., Mycobacterium ostraviense sp. nov. to replace the former subtype IV. By showing a close genetic relatedness, amonophyletic origin, and overlapping phenotypes, our findings support the recognition of the M. kansasii complex (MKC), accommodating all M. kansasii-derived species and Mycobacterium gastri. None of the most commonly used taxonomic markers was shown to accurately distinguish all the MKC species. Likewise, no species-specific phenotypic characteristics were found allowing for species differentiation within the complex, except the non-photochromogenicity of M. gastri. To distinguish, most reliably, between the MKC species, and between M. kansasii and M. persicum in particular, whole-genome-based approaches should be applied. In the absence of clear differences in the distribution of the virulence-associated region of difference 1 genes among the M. kansasii-derived species, the pathogenic potential of each of these species can only be speculatively assessed based on their prevalence among the clinically relevant population. Large-scale molecular epidemiological studies are needed to provide a better understanding of the clinical significance and pathobiology of the MKC species. The results of the in vitro drug susceptibility profiling emphasize the priority of rifampicin administration in the treatment of MKC-induced infections, while undermining the use of ethambutol, due to a high resistance to this drug.
