On September 6 to 9, 2017, in Mainz, Germany, the Third International Cancer Immunotherapy Conference was hosted jointly by the Cancer Research Institute, the Association for Cancer Immunotherapy, the European Academy of Tumor Immunology, and the American Association for Cancer Research. For the third straight year, more than 1,400 people attended the four-day event, which covered the latest advances in cancer immunology and immunotherapy. This report provides an overview of the main topics discussed. Cancer Immunol Res; 6(1); 10-13. ©2017 AACR.

The Westpfalz is a mainly rural region in the southwestern part of the German state of Rhineland-Palatinate with 527,000 inhabitants and demonstrates a higher than average cardiovascular mortality compared to the rest of Germany. The reasons are not known. Our study attempted to investigate whether significant deficits in knowledge of the population on cardiovascular emergencies, the accessibility of emergency medical services (EMS) or the different responsibilities and abilities of the medical facilities could be held responsible for this. These factors are of the utmost importance for the timely initiation and administration of curative therapeutic strategies.

The 24 hour activity patterns of three non-native gobiids (round goby Neogobius melanostomus, Western tubenose goby Proterorhinus semilunaris and bighead goby Ponticola kessleri) were assessed over 46 consecutive months between 2011 and 2014 from their occurrence in the cooling water intake of a nuclear power plant on the River Rhine, Germany. In total, 117717 gobiids were identified and classified. The occurrence of all three species varied strongly between sampling years, and species-specific activity triggers were identified. The activity of juveniles of all three gobiids species was positively temperature dependent while adult tubenose goby activity appeared to be negatively temperature dependent. Increasing fluvial discharge in the adjoining main river stimulated the activity of juvenile round goby but inhibited activity of adult tubenose goby. Except for adult bighead goby, activity was also structured by time of day, but with no uniform mean. Meteorological factors such as precipitation, air pressure and duration of sunshine hours had little or no influence on gobiid activity. On selected rare occasions, mainly at night, all three species exhibited pulsed swarming behaviour, with thousands of individuals recorded in the intake water. Round goby swarms exhibited both the highest intensity and the largest swarming individuals, suggesting a potential competitive advantage over tubenose and bighead goby. Electric fishing surveys in natural river stretches corroborated this observation. Negative effects on the native fish fauna were apparent only for the bullhead, Cottus gobio. The activity triggers identified offer a unique insight into the invasion mechanisms of these ecosystem-changing non-native gobiids.

A 48-year-old female patient presented to the ENT department of the University Medical Center of the Johannes Gutenberg University Mainz with subfebrile temperatures, one-sided nasal obstruction, and left-sided cephalgia. Clinical examination and CT scans showed a mass occupying the left nasal cavity and left paranasal sinuses. Further diagnosis and histopathological examination showed an HIV-associated plasmablastic lymphoma of the left paranasal sinuses. This case report with literature review discusses the diagnosis and treatment of this rare nasal tumor.

Following the amendment of the Medical Licensure Act (ÄAppO) in 2012, pain medicine was introduced as a mandatory subject for students during undergraduate medical training. Medical schools were required to define and to implement adequate curricular and formal teaching structures based on interdisciplinary and multiprofessional requirements according to the curriculum for pain medicine of the German Pain Society. These aspects were considered in the new interdisciplinary curriculum for pain medicine, the so-called Mainz model.

Directed assembly of triblock copolymer worms to produce nanostructured fibers is achieved via colloid electrospinning. These copolymer worms are conveniently prepared by polymerization-induced self-assembly in concentrated aqueous dispersion. Addition of a second water-soluble component, poly(vinyl alcohol), is found to be critical for the production of well-defined fibers: trial experiments performed using the worms alone produce only spherical microparticles. Transmission electron microscopy studies confirm that the worm morphology survives electrospinning and the worms become orientated parallel to the main axis of the fibers during their generation. The average deviant angle (θdev ) between the worm orientation and fiber axis decreases from 17° to 9° as the worm/PVA mass ratio increases from 1.15:1 to 5:1, indicating a greater degree of worm alignment within fibers with higher worm contents and smaller fiber diameters. Thus triblock copolymer fibers of ≈300 ± 120 nm diameter can be readily produced that comprise aligned worms on the nanoscale.

The main advantage of transaxillary robotic-assisted thyroid surgery (TRAT) is the avoidance of a scar on the neck. As TRAT is still rarely performed in Germany, there are not yet any German reports on acceptance, operation times and complications.

Front Cover: Investigating materials for optoelectronic applications under the focus of self-organization is fascinating, both from a scientific and industrial point of view, bringing together scientists from different countries and areas of knowledge. The design symbolically represents the transnational cooperation within the International Research Training Group “Self-Organized Materials for Optoelectronics” (IRTG 1404) as an assembly station: Within the IRTG 1404 the knowledge and resources from Korean and German supply lines-Seoul National University, Hannam University, Johannes Gutenberg University Mainz, and the Max Planck Institute for Polymer Research-are combined together to generate new scientific results on this interdisciplinary topic.

The German transplantation system is in a crisis due to a lack of donor organs. Information campaigns are one of the main approaches to increase organ donation rates. Since 2012, German health insurance funds are obliged by law to inform their members about organ donation. We raised the hypothesis: The willingness to sign a donor card rises due to the subsequent increase of specific knowledge by receiving the information material of the health insurance funds.
