- The genus Ulva is globally distributed and has been thoroughly studied because of its functional biochemical composition, rapid growth rates and opportunistic features, and interest in Ulva cultivation is growing worldwide. In Europe, mostly near- and on-shore flow-through cultivation systems are used, and land-based recirculating aquaculture systems (RAS) using fresh water or artificial seawater have not been developed for Ulva. While RAS provides quality control and can be located inland, maintenance costs are high. Using selected strains adapted to low-salinity could reduce seawater production costs and improve the economic feasibility. Therefore, our study assessed how salinity can be used as a tool for strain selection and optimization of functional traits. Growth rates and antioxidant activity of three species (four strains) of tubular and foliose Ulva from the NE-Atlantic and Mediterranean (foliose: Ulva lacinulata – two geographical strains, tubular: Ulva linza and Ulva flexuosa) were followed for three weeks at salinities ranging from 10 to 30 PSU. The tubular strains achieved optimal growth at a lower salinity than U. lacinulata. However, growth rates of both foliose strains were higher than of tubular strains, even at sub-optimal salinity. Therefore, U. lacinulata is a good candidate for RAS with artificial seawater, and the cost of salt can be reduced by up to 33.3% (20 PSU) without significantly reducing the growth rate of U. lacinulata. Higher antioxidant activity was achieved by reducing the salinity to 10 PSU for 10 days, suggesting that the functional traits of cultivated Ulva lacinulata can be optimized prior to harvest.

- Aim Recording the frequency of screenings for problematic alcohol consumption by professionals involved in the health care of respective patients. The German S3-guideline screening, diagnosis and treatment of alcohol-related disorders recommends the use of questionnaire-based screenings for all patients in all settings.Methods Cross-sectional survey on screening frequency among general practitioners, gynecologists, psychiatrists, child- and adolescent therapists, psychotherapists, social workers and midwives. Logistic regression was used to explore how healthcare professionals' attributes were associated with the implementation of screenings.Results With response rates of about 20%, health care professionals reported using screening instruments for an average of 6.9% of all patients during the previous four weeks. Most of the time, custom-made questions were used instead of the recommended instruments (AUDIT, AUDIT-C). Higher screening rates were reported for patients with newly diagnosed hypertension (21.2%), alcohol-related disorders (43.3%) and mental disorders (39.3%). Knowledge of the guideline was associated with implementation of screenings (OR=4.67; 95% KI 1.94-11.25, p<0.001).Conclusions Comprehensive screening for problematic alcohol use with questionnaire-based instruments in accordance with guidelines is far from being routinely implemented in the studied health care settings. Measures to increase the knowledge of the guidelines are necessary in order to increase the frequency of alcohol screening in health care.

- Objective: Although targeted approaches have become available in second- and third-line settings, platinum-based chemotherapy remains the standard first-line treatment for advanced muscle-invasive bladder cancer (MIBC). Therefore, the prediction of platinum resistance is of utmost clinical importance. Methods: In this study, we established a routine compatible method for the molecular classification of MIBC samples according to various classification systems and applied this method to evaluate the impact of subtypes on survival after adjuvant chemotherapy. This retrospective study included 191 patients with advanced MIBC (pT≥3 or pN+) who underwent radical cystectomy, with or without adjuvant chemotherapy. A 48-gene panel and classifier rule set were established to determine molecular subtypes according to TCGA, MDA, LundTax, and Consensus classifications. Additionally, 12 single platinum-predictive candidate genes were assessed. The results were correlated with patients' clinicopathological and follow-up data and were validated using independent data sets. Results: Our final evaluation of 159 patients demonstrated better survival in the luminal groups for those who received chemotherapy compared with those who did not. In contrast, no such differences were observed in basal subtypes. The use of chemotherapy was associated with better survival in patients with high APOBEC3G expression (p < 0.002). This association was confirmed using an independent data set of patients who received neoadjuvant platinum therapy. Conclusions: The proposed method robustly replicates the most commonly used transcriptome-based subtype classifications from paraffin-embedded tissue samples. The luminal, but not basal, molecular subtypes had the greatest benefit from adjuvant platinum therapy. We identified and validated APOBEC3G as a novel predictive marker for platinum-treated patients.
