Disease characteristics and clinical outcome over two decades from the Swiss pulmonary hypertension registry

Pulmonary hypertension (PH), especially pulmonary arterial and chronic thromboembolic pulmonary hypertension (PAH/CTEPH), are rare and progressive conditions. Despite recent advances in treatment and prognosis, PH is still associated with impaired quality of life and survival. Long-term PH-registry data provide information on the changing PH-epidemiology and may help to direct resources to patient's needs. This retrospective analysis of the Swiss Pulmonary Hypertension Registry includes patients newly diagnosed with PH (mainly PAH/CTEPH) registered from January 2001 to June 2019 at 13 Swiss hospitals. Patient characteristics (age, body mass index, gender, diagnosis), hemodynamics at baseline, treatment, days of follow-up, and events (death, transplantation, pulmonary endarterectomy, or loss to follow-up) at last visit were analyzed. Patients were stratified into four time periods according to their date of diagnosis. Survival was analyzed overall and separately for PAH/CTEPH and time periods. 1427 PH patients were included (thereof 560 PAH, 383 CTEPH). Over the years, age at baseline (mean ± SD) significantly increased from 59 ± 14 years in 2001–2005 to 66 ± 14 years in 2016–2019 (p < 0.001) while the gender distribution tended toward equality. Mean pulmonary artery pressure and pulmonary vascular resistance significantly decreased over time (from 46 ± 15 to 41 ± 11 mmHg, respectively, 9 ± 5 to 7 ± 4 WU, p < 0.001). Three-year survival substantially increased over consecutive periods from 69% to 91% (for PAH 63%–95%, for CTEPH 86%–93%) and was poorer in PAH than CTEPH independently of time period (p < 0.001). Most patients were treated with mono- or combination therapy and an increasing number of CTEPH underwent pulmonary endarterectomy (40% 2016–2019 vs. 15% 2001–2005). This long-term PH registry reveals that over two decades of observation, newly diagnosed patients are older, less predominantly female, have less impaired hemodynamics and a better survival

Steigerung der Wertschöpfung ökologisch angebauter Marktfrüchte durch Optimierung des Managements der Bodenfruchtbarkeit

Das interdisziplinäre Bodenfruchtbarkeitsprojekt beschäftigte sich in vier Versuchs- und fünf Projektjahren mit den Zusammenhängen zwischen dem Anbau von Körnerleguminosen und Bodenfruchtbarkeit, insbesondere auf viehschwachen bzw. viehlosen Biobetrieben. In Erhebungen auf 32 Praxisbetrieben konnten bislang allenfalls vermutete Zusammenhänge wie z. B. die Zunahme des Unkrautdeckungsgrades mit zunehmendem Humusgehalt bestätigt werden. Die Ergebnisse deuten auch darauf hin, dass z. B. die Anbauabstände im Erbsenanbau im Vergleich zu praxisüblichen Empfehlungen vergrößert werden müssen, daneben ergaben sich auch interessante neue Anknüpfungspunkte. Hinsichtlich der Leguminosengesundheit ermöglicht die neu entwickelte Differenzialdiagnose, die Ursache für ggf. auftretende „Leguminosenmüdigkeit“ einzugrenzen bzw. Praxisschläge vor dem Anbau auf Krankheitsrisiken zu testen. Im Projekt konnte außerdem gezeigt werden, dass Grüngutkomposte die Wurzelgesundheit von Erbsen deutlich verbessern können. Es wurden darüber hinaus verschiedene Methoden zur Kompostapplikation zu Körnerleguminosen geprüft und für den Praxiseinsatz optimiert. Neben Grüngutkomposten spielt auch Grünguthäcksel eine wichtige Rolle bei der Nährstoffversorgung von Leguminosen. Oberflächlich leicht eingearbeiteter Grünguthäcksel ist in der Lage, das Wachstum der Kulturpflanzen sowohl durch eine unkrautunterdrückende Wirkung als auch durch Schutz vor Verschlämmung sowie erhöhte Wasserinfiltrationsraten zu verbessern. Die Ergebnisse zum Landtechnikeinsatz zeigen, dass schon geringe Belastungen zu Bodenverdichtungen und damit zu Ertragsrückgängen in Erbsen führen, weshalb Maßnahmen zu Reduzierung des Bodendrucks essenziell sind. Hinsichtlich der beikrautunterdrückenden Wirkung des Gemengeanbaus von Erbsen in Kombination mit Hafer konnte gezeigt werden, dass der Gemengeanbau das erhöhte Beikrautaufkommen bei flachwendender Bodenbearbeitung erfolgreich ausgleichen kann und hinsichtlich der Ertragssicherheit Vorteile mit sich bringt. Nicht zuletzt machte das Projekt auf die Vorteile und Potenziale des Wintererbsenanbaus aufmerksam. Über einen fortlaufenden Wissenstransfer war das Projekt von Beginn an in der landwirtschaftlichen Praxis präsent

Dihydropyrimidine Dehydrogenase Testing prior to Treatment with 5-Fluorouracil, Capecitabine, and Tegafur: A Consensus Paper

Background: 5-Fluorouracil (FU) is one of the most commonly used cytostatic drugs in the systemic treatment of cancer. Treatment with FU may cause severe or life-threatening side effects and the treatment-related mortality rate is 0.2–1.0%. Summary: Among other risk factors associated with increased toxicity, a genetic deficiency in dihydropyrimidine dehydrogenase (DPD), an enzyme responsible for the metabolism of FU, is well known. This is due to variants in the DPD gene (DPYD). Up to 9% of European patients carry a DPD gene variant that decreases enzyme activity, and DPD is completely lacking in approximately 0.5% of patients. Here we describe the clinical and genetic background and summarize recommendations for the genetic testing and tailoring of treatment with 5-FU derivatives. The statement was developed as a consensus statement organized by the German Society for Hematology and Medical Oncology in cooperation with 13 medical associations from Austria, Germany, and Switzerland. Key Messages: (i) Patients should be tested for the 4 most common genetic DPYD variants before treatment with drugs containing FU. (ii) Testing forms the basis for a differentiated, risk-adapted algorithm with recommendations for treatment with FU-containing drugs. (iii) Testing may optionally be supplemented by therapeutic drug monitorin

CO-FREE Alternative Test Products for Copper Reduction in Agriculture

The project CO-FREE (2012-2016) aimed to develop strategies to replace/reduce copper use in organic, integrated and conventional farming. CO-FREE alternative test products (CTPs) were tested and integrated together with decision support systems, disease-tolerant varieties, and innovative breeding goals (ideotypes) into improved management strategies. CO-FREE focused on apple/apple scab (Venturia inaequalis), grape/downy mildew (Plasmopara viticola), and tomato and potato/late blight (Phytophthora infestans). Starting point of the project were ten CTPs with direct or indirect modes of action including Trichoderma atroviride SC1 and protein extract SCNB, Lysobacter spp., yeast-based derivatives, Cladosporium cladosporioides H39, the oligosaccharidic complex COS-OGA, Aneurinibacillus migulanus and Xenorhabdus bovienii, sage (Salvia officinalis) extract, liquorice (Glycyrrhiza glabra) extract, PLEX- and seaweed plant extracts. As the project progressed, further promising CTPs were included by the partners. Field trials were performed in different European countries in 2012-2015 following EPPO standards. In the first years, stand-alone applications of CTPs were tested. In the following years these were integrated into complete strategies. Effects on main and further diseases, on yield and on non-target organisms were assessed. Here, field trial results with CTPs are summarized

Species Delimitation in Taxonomically Difficult Fungi: The Case of Hymenogaster

False truffles are ecologically important as mycorrhizal partners of trees and evolutionarily highly interesting as the result of a shift from epigeous mushroom-like to underground fruiting bodies. Since its first description by Vittadini in 1831, inappropriate species concepts in the highly diverse false truffle genus Hymenogaster has led to continued confusion, caused by a large variety of prevailing taxonomical opinions.In this study, we reconsidered the species delimitations in Hymenogaster based on a comprehensive collection of Central European taxa comprising more than 140 fruiting bodies from 20 years of field work. The ITS rDNA sequence dataset was subjected to phylogenetic analysis as well as clustering optimization using OPTSIL software.Among distinct species concepts from the literature used to create reference partitions for clustering optimization, the broadest concept resulted in the highest agreement with the ITS data. Our results indicate a highly variable morphology of H. citrinus and H. griseus, most likely linked to environmental influences on the phenology (maturity, habitat, soil type and growing season). In particular, taxa described in the 19(th) century frequently appear as conspecific. Conversely, H. niveus appears as species complex comprising seven cryptic species with almost identical macro- and micromorphology. H. intermedius and H. huthii are described as novel species, each of which with a distinct morphology intermediate between two species complexes. A revised taxonomy for one of the most taxonomically difficult genera of Basidiomycetes is proposed, including an updated identification key. The (semi-)automated selection among species concepts used here is of importance for the revision of taxonomically problematic organism groups in general

Consensus Recommendation for Mouse Models of Ocular Hypertension to Study Aqueous Humor Outflow and Its Mechanisms.

Due to their similarities in anatomy, physiology, and pharmacology to humans, mice are a valuable model system to study the generation and mechanisms modulating conventional outflow resistance and thus intraocular pressure. In addition, mouse models are critical for understanding the complex nature of conventional outflow homeostasis and dysfunction that results in ocular hypertension. In this review, we describe a set of minimum acceptable standards for developing, characterizing, and utilizing mouse models of open-angle ocular hypertension. We expect that this set of standard practices will increase scientific rigor when using mouse models and will better enable researchers to replicate and build upon previous findings
