Background: The approval of everolimus (EVE) for the treatment of angiomyolipoma (2013), subependymal giant cell astrocytoma (2013) and drug-refractory epilepsy (2017) in patients with tuberous sclerosis complex (TSC) represents the first disease-modifying treatment option available for this rare and complex genetic disorder. Objective: The objective of this study was to analyse the use, efficacy, tolerability and treatment retention of EVE in patients with TSC in Germany from the patient’s perspective. Methods: A structured cross-age survey was conducted at 26 specialised TSC centres in Germany and by the German TSC patient advocacy group between February and July 2019, enrolling children, adolescents and adult patients with TSC. Results: Of 365 participants, 36.7% (n = 134) reported the current or past intake of EVE, including 31.5% (n = 115) who were taking EVE at study entry. The mean EVE dosage was 6.1 ± 2.9 mg/m2 (median: 5.6 mg/m2, range 2.0–15.1 mg/m2) in children and adolescents and 4 ± 2.1 mg/m2 (median: 3.7 mg/m2, range 0.8–10.1 mg/m2) in adult patients. An early diagnosis of TSC, the presence of angiomyolipoma, drug-refractory epilepsy, neuropsychiatric manifestations, subependymal giant cell astrocytoma, cardiac rhabdomyoma and overall multi-organ involvement were associated with the use of EVE as a disease-modifying treatment. The reported efficacy was 64.0% for angiomyolipoma (75% in adult patients), 66.2% for drug-refractory epilepsy, and 54.4% for subependymal giant cell astrocytoma. The overall retention rate for EVE was 85.8%. The retention rates after 12 months of EVE therapy were higher among adults (93.7%) than among children and adolescents (88.7%; 90.5% vs 77.4% after 24 months; 87.3% vs 77.4% after 36 months). Tolerability was acceptable, with 70.9% of patients overall reporting adverse events, including stomatitis (47.0%), acne-like rash (7.7%), increased susceptibility to common infections and lymphoedema (each 6.0%), which were the most frequently reported symptoms. With a total score of 41.7 compared with 36.8 among patients not taking EVE, patients currently being treated with EVE showed an increased Liverpool Adverse Event Profile. Noticeable deviations in the sub-items ‘tiredness’, ‘skin problems’ and ‘mouth/gum problems’, which are likely related to EVE-typical adverse effects, were more frequently reported among patients taking EVE. Conclusions: From the patients’ perspective, EVE is an effective and relatively well-tolerated disease-modifying treatment option for children, adolescents and adults with TSC, associated with a high long-term retention rate that can be individually considered for each patient. Everolimus therapy should ideally be supervised by a centre experienced in the use of mechanistic target of rapamycin inhibitors, and adverse effects should be monitored on a regular basis.
Under certain conditions, secondary organic aerosol (SOA) particles can exist in the atmosphere in an amorphous solid or semi-solid state. To determine their relevance to processes such as ice nucleation or chemistry occurring within particles requires knowledge of the temperature and relative humidity (RH) range for SOA to exist in these states. In the Cosmics Leaving Outdoor Droplets (CLOUD) experiment at The European Organisation for Nuclear Research (CERN), we deployed a new in situ optical method to detect the viscous state of α-pinene SOA particles and measured their transition from the amorphous highly viscous state to states of lower viscosity. The method is based on the depolarising properties of laboratory-produced non-spherical SOA particles and their transformation to non-depolarising spherical particles at relative humidities near the deliquescence point. We found that particles formed and grown in the chamber developed an asymmetric shape through coagulation. A transition to a spherical shape was observed as the RH was increased to between 35 % at −10 °C and 80 % at −38 °C, confirming previous calculations of the viscosity-transition conditions. Consequently, α-pinene SOA particles exist in a viscous state over a wide range of ambient conditions, including the cirrus region of the free troposphere. This has implications for the physical, chemical, and ice-nucleation properties of SOA and SOA-coated particles in the atmosphere.
Abrasion-ablation models and the empirical EPAX parametrization of projectile fragmentation are described. Their cross section predictions are compared to recent data of the fragmentation of secondary beams of neutron-rich, unstable 19,20,21O isotopes at beam energies near 600 MeV/nucleon as well as data for stable 17,18O beams.
Knowledge about the biogeographic affinities of the world’s tropical forests helps to better understand regional differences in forest structure, diversity, composition, and dynamics. Such understanding will enable anticipation of region-specific responses to global environmental change. Modern phylogenies, in combination with broad coverage of species inventory data, now allow for global biogeographic analyses that take species evolutionary distance into account. Here we present a classification of the world’s tropical forests based on their phylogenetic similarity. We identify five principal floristic regions and their floristic relationships: (i) Indo-Pacific, (ii) Subtropical, (iii) African, (iv) American, and (v) Dry forests. Our results do not support the traditional neo- versus paleotropical forest division but instead separate the combined American and African forests from their Indo-Pacific counterparts. We also find indications for the existence of a global dry forest region, with representatives in America, Africa, Madagascar, and India. Additionally, a northern-hemisphere Subtropical forest region was identified with representatives in Asia and America, providing support for a link between Asian and American northern-hemisphere forests.
Meeting Abstract : Deutsche Gesellschaft für Chirurgie. 125. Kongress der Deutschen Gesellschaft für Chirurgie. Berlin, 22.-25.04.2008 Einleitung: Über 4 Millionen Menschen leben in Deutschland schätzungsweise mit chronischen Wunden. Aufgrund der demographischen Entwicklung unserer Gesellschaft ist mit einem weiteren Anstieg der zu nicht, oder nur zögerlich heilenden Wunden führenden Erkrankungen diabetisches Fußsyndrom, chronisch venöse Insuffizienz und pAVK auszugehen. Dennoch ist die moderne hydroaktive Wundbehandlung in Deutschland nicht flächendeckend etabliert. Gründe hierfür liegen unter anderem in dem unüberschaubaren Produktsortiment, der unzureichenden Vergütung vor allem im ambulanten Versorgungssektor und in der mangelhaften ärztlichen Ausbildung in Bezug auf Wundtherapie. Ein standardisiertes Wundbehandlungsschema erleichtert die stadiengerechte Anwendung moderner Wundauflagen und dient als nachvollziehbare Entscheidungsgrundlage in der Auswahl der erforderlichen Wundprodukte. Material und Methoden: Anhand eines Bogens werden vier Kriterien (Wundstadium, Wundexsudation, Wundtiefe und Wundinfektion) zur Beurteilung einer Wunde erfasst. Die fotographische Abbildung der verschiedenen Wundstadien erlaubt eine sichere visuelle Zuordnung durch den Therapeuten. Nach Analyse dieser S.E.T.I. Kriterien ergibt sich eine eindeutige stadiengerechte Produktzuordnung, die auch dem weniger geübten eine sichere Anwendung der verschiedenen Produktgruppen ermöglicht. Ergebnisse: Dieser Behandlungsstandard wurde zwischenzeitlich an 3 Kliniken der Maximalversorgung und in einem integrierten Versorgungsmodell zum diabetischen Fußsyndrom etabliert und stellt einen Bestandteil für ein weiteres IV Modell zur pAVK dar. Neben ökonomischen Vorteilen (reduzierte Lagerhaltungskosten, Straffung des Produktsortiments, günstigere Bezugskonditionen) lässt sich eine Verbesserung in der Behandlungsqualität, eine verkürzte stationäre Behandlungsdauer sowie eine vereinfachte Umsetzung einer sektorenübergreifenden Wundversorgung erzielen. Schlussfolgerung: Die Anwendung eines Therapiestandards für die stadiengerechte Behandlung chronischer Wunden ermöglicht eine Anwenderunabhängige gleich bleibend hohe Qualität sowie eine wesentlich vereinfachte Orientierung in dem Produktsortiment. Hierdurch wird weiterhin ein Beitrag zur Schnittstellenoptimierung zwischen dem stationären und ambulanten Versorgungssektor bei chronischen Wunden geleistet. Ein verbindlicher interdisziplinärer und interprofessioneller Wundbehandlungsstandard stellt eine unverzichtbare Qualitätssicherungsmaßnahme in der Wundbehandlung dar.
In der Stadt Wolfenbüttel wurde 1592 am damaligen Hof der Welfenherzöge von Braunschweig und Lüneburg das erste stehende Theater in Deutschland mit einem festen Ensemble gegründet. Das heutige "Lessingtheater" wurde im klassizistischen Stil erbaut und 1909 eröffnet. Es wird als Bespieltheater betrieben. Zur Zeit bietet der "Kulturbund der Lessingstadt Wolfenbüttel e. V." (gegr. 1946) im Auftrage der Stadt ein Programm von 50 bis 70 Vorstellungen jährlich auf dieser Vollbühne (10 m x 8 m) an mit jetzt ca. 600, später dann ca. 500 Zuschauerplätzen. Dieses Programm setzt sich zusammen aus Tourneetheateraufführungen, aus Gastspielen des Nordharzer Städtebundtheaters Halberstadt/ Quedlinburg und der Landesbühne Rheinland-Pfalz. Zu seinem 100-jährigen Bestehen im Jahr 2009 steht eine umfangreiche und umfassende bauliche Erneuerung an, um das Gebäude den Erfordernissen der Zeit in bühnentechnischer wie architektonischer Hinsicht anzupassen. Die Vorstellungen darüber, wie das Theater zukünftig räumlich gestaltet und ausgestattet und welche bühnentechnische Ausstattung dazu eingerichtet werden sollte, werden seit einiger Zeit in Rat und Verwaltung, bei möglichen Geldgebern sowie in der kulturpolitisch interessierten Öffentlichkeit Wolfenbüttels erörtert.
The blue pine wood borer (Phaenops cyanea) and the black pine sawyer beetle (Monochamus galloprovincialis) (Fig. 1) both are pests of the white pine (Pinus silvestris) and other Pinus species. Both insects have nearly the same demands regarding their breeding site. Larval development requires a fresh, unwilted inner bark. An infestation occurs on freshly cut trees or on trees suffering from stress (e.g. after dry seasons, loss of needles caused by feeding caterpillars or damage by forest fires). Phaenops cyanea detects susceptible pines by their volatile emissions (SCHÜTZ et al. 2004) and is able to infest the trees already at a low stress level. During feeding the larvae avoid the resin ducts of the tree and thus evade the oleoresin defence. The beetle is endemic in Europe and – under favourable climatic conditions – can cause substantial damage to pine forests. It is the most significant bark-breeding beetle of white pine in the lowlands of north-eastern Germany. Monochamus galloprovincialis is found in Europe and northern Africa. The larvae tend to a more copious feeding which makes them more susceptible to the oleoresin defence of the tree. Thus, M. galloprovincialis prefers trees that are weakened by a higher degree of stress. The economic damage caused by feeding of thebeetle is low. However, the beetle has gained a special attention of forest scientists because of its association with the nematode Bursaphelenchus xylophilus which is causing the pine wilt disease (PWD) in Pinus. The only outbreak of the PWD within Europe is limited to an area of 258.000 ha in Portugal. (MOTA et al. 1999).
Die von Wolfgang Ludwig hinterlassene Pflanzensammlung im Marburger Herbar wurde aufbereitet und dokumentiert. Vorgestellt werden Belege aus der in über 70 Jahren (1938–2010) entstandenen Sammlung, die für die hessische Flora bislang nicht bekannt waren sowie Belege zu inzwischen ausgestorbenen, sehr seltenen oder sonstigen bemerkenswerten Arten.
The Tarim River basin, located in Xinjiang, NW China, is the largest endorheic river basin in China and one of the largest in all of Central Asia. Due to the extremely arid climate, with an annual precipitation of less than 100 mm, the water supply along the Aksu and Tarim rivers solely depends on river water. This is linked to anthropogenic activities (e.g., agriculture) and natural and semi-natural ecosystems as both compete for water. The ongoing increase in water consumption by agriculture and other human activities in this region has been enhancing the competition for water between human needs and nature. Against this background, 11 German and 6 Chinese universities and research institutes have formed the consortium SuMaRiO (Sustainable Management of River Oases along the Tarim River; http://www.sumario.de), which aims to create a holistic picture of the availability of water resources in the Tarim River basin and the impacts on anthropogenic activities and natural ecosystems caused by the water distribution within the Tarim River basin. On the basis of the results from field studies and modeling approaches as well as from suggestions by the relevant regional stakeholders, a decision support tool (DST) will be implemented that will then assist stakeholders in balancing the competition for water, acknowledging the major external effects of water allocation to agriculture and to natural ecosystems. This consortium was formed in 2011 and is funded by the German Federal Ministry of Education and Research. As the data collection phase was finished this year, the paper presented here brings together the results from the fields from the disciplines of climate modeling, cryology, hydrology, agricultural sciences, ecology, geoinformatics, and social sciences in order to present a comprehensive picture of the effects of different water availability schemes on anthropogenic activities and natural ecosystems along the Tarim River. The second objective is to present the project structure of the whole consortium, the current status of work (i.e., major new results and findings), explain the foundation of the decision support tool as a key product of this project, and conclude with application recommendations for the region. The discharge of the Aksu River, which is the major tributary of the Tarim, has been increasing over the past 6 decades. From 1989 to 2011, agricultural area more than doubled: cotton became the major crop and there was a shift from small-scale to large-scale intensive farming. The ongoing increase in irrigated agricultural land leads to the increased threat of salinization and soil degradation caused by increased evapotranspiration. Aside from agricultural land, the major natural and semi-natural ecosystems are riparian (Tugai) forests, shrub vegetation, reed beds, and other grassland, as well as urban and peri-urban vegetation. Within the SuMaRiO cluster, focus has been set on the Tugai forests, with Populus euphratica as the dominant tree species, because these forests belong to the most productive and species-rich natural ecosystems of the Tarim River basin. At sites close to the groundwater, the annual stem diameter increments of Populus euphratica correlated with the river runoffs of the previous year. However, the natural river dynamics cease along the downstream course and thus hamper the recruitment of Populus euphratica. A study on the willingness to pay for the conservation of the natural ecosystems was conducted to estimate the concern of the people in the region and in China's capital. These household surveys revealed that there is a considerable willingness to pay for conservation of the natural ecosystems, with mitigation of dust and sandstorms considered the most important ecosystem service. Stakeholder dialogues contributed to creating a scientific basis for a sustainable management in the future.
Herr Wolff, in der Ausgabe von Forschung Frankfurt zum Jubiläumsjahr werden Sie mit dem Satz zitiert: "Die Offenheit der Debatten, die die 68er erkämpft haben, lässt sich nicht mehr zurücknehmen." Vor Kurzem wurde an der Goethe-Universität heftig über Meinungsfreiheit gestritten. Die Frage war: Darf man den Polizeigewerkschafter Rainer Wendt zur Diskussion an die Uni einladen. Hat Ihre Aussage nach wie vor Bestand? ...
Die Auen naturnaher Ströme und großer Flüsse weisen eine Vielzahl unterschiedlicher Auengewässer auf. Dazu zählen auch die Altgewässer, d. h. ehemals durchflossene Flussabschnitte oder Verzweigungsstrecken, die heute vom Fließgewässer abgetrennt sind und oft einen Standgewässercharakter aufweisen. Ihre natürliche Entstehung verdanken sie der Dynamik der Fließgewässer z. B. durch Gewässerbettverlagerungen oder Mäanderdurchbrüche. In Abhängigkeit von ihrer Entfernung zum Fluss und je nachdem, ob sie noch eine Verbindung zum Fließgewässer haben, nur noch bei Hochwasser überflutet werden oder außerhalb des Einflussbereichs des Stroms liegen, durchlaufen sie verschiedene Entwicklungs- bzw. Sukzessionsstadien, die von frühen Pionierstadien bis zur völligen Verlandung reichen können. Diese Vielgestaltigkeit ist Grundlage für das Vorkommen unterschiedlicher Lebensgemeinschaften mit teilweise stark bedrohten und naturschutzfachlich bedeutsamen Pflanzen- und Tierarten und europaweit geschützter Lebensräume. Reichhoff (2003) gibt allein für das Mittelelbegebiet 59 verschiedene Pflanzengesellschaften an, die an Altgewässer gebunden sind.
Background and purpose: Impaired kidney function is associated with an increased risk of vascular events in acute stroke patients, when assessed by single measurements of estimated glomerular filtration rate (eGFR). It is unknown whether repeated measurements provide additional information for risk prediction.
Methods: The MonDAFIS (Systematic Monitoring for Detection of Atrial Fibrillation in Patients with Acute Ischemic Stroke) study randomly assigned 3465 acute ischemic stroke patients to either standard procedures or an additive Holter electrocardiogram. Baseline eGFR (CKD-EPI formula) were dichotomized into values of < versus ≥60 ml/min/1.73 m2. eGFR dynamics were classified based on two in-hospital values as “stable normal” (≥60 ml/min/1.73 m2), “increasing” (by at least 15% from baseline, second value ≥ 60 ml/min/1.73 m2), “decreasing” (by at least 15% from baseline of ≥60 ml/min/1.73 m2), and “stable decreased” (<60 ml/min/1.73 m2). The composite endpoint (stroke, major bleeding, myocardial infarction, all-cause death) was assessed after 24 months. We estimated hazard ratios in confounder-adjusted models.
Results: Estimated glomerular filtration rate at baseline was available in 2947 and a second value in 1623 patients. After adjusting for age, stroke severity, cardiovascular risk factors, and randomization, eGFR < 60 ml/min/1.73 m2 at baseline (hazard ratio [HR] = 2.2, 95% confidence interval [CI] = 1.40–3.54) as well as decreasing (HR = 1.79, 95% CI = 1.07–2.99) and stable decreased eGFR (HR = 1.64, 95% CI = 1.20–2.24) were independently associated with the composite endpoint. In addition, eGFR < 60 ml/min/1.732 at baseline (HR = 3.02, 95% CI = 1.51–6.10) and decreasing eGFR were associated with all-cause death (HR = 3.12, 95% CI = 1.63–5.98).
Conclusions: In addition to patients with low eGFR levels at baseline, also those with decreasing eGFR have increased risk for vascular events and death; hence, repeated estimates of eGFR might add relevant information to risk prediction.
Post 9/11 haben Forschungen zur Geschichte des "Terrorismus" weltweit Konjunktur. Kaum eine neuere Überblicksdarstellung zur Geschichte der politischen Gewalt und der Staatsverbrechen kommt ohne "Terrorismus" und den Referenzpunkt "9/11" aus, darunter die auf einer älteren Monographie basierende, 2012 publizierte und auf den universitären Unterricht bzw. ein breiteres Lesepublikum zielende Introduction to Political Crime von Jeffrey Ian Ross, der 2011 erschienene historische Überblick über die Geschichte der Crimes Against the State. From Treason to Terrorism von Michael Head oder die von mehreren französischen Autoren 2010 verfasste Darstellung historischer Terrorismusphänomene Terrorismes: Histoire et Droit. Im Gegensatz zu älteren Darstellungen erscheint "Terrorismus" inzwischen als zentraler Zugang zur Geschichte politischer Gewalt, auch im Hinblick auf die grenzübergreifenden und internationalen Dimensionen sowie die rechtlichen und polizeilichen Gegenmaßnahmen des counter-terrorism. Allerdings konzentrieren sich die historische Forschung wie die Politik- und Rechtswissenschaft auf den modernen zeitgenössischen "Terrorismus" seit dem Ersten Weltkrieg und diskutieren Erscheinungsformen, Ursachen sowie Strategien zu dessen Bekämpfung und Bewältigung. Nur wenige der in den letzten Jahren erschienenen, teils auch neu aufgelegten Gesamtdarstellungen gehen zeitlich weiter zurück und beziehen die Zeit nach der Etablierung des "Terrorismusbegriffs" durch die Französische Revolution mit ein oder greifen gar bis zur Antike aus. So beginnt Randall D. Law seine 2009 publizierte Geschichte des Terrorismus mit dem Kapitel Terror and Tyrannicide in the Ancient World, gefolgt von Abschnitten über das Mittelalter und die Frühe Neuzeit. Antike und Mittelalter nur kurz streifend, sucht Martin A. Miller dagegen die Foundations of Modern Terrorism in der politischen Gewalt des frühneuzeitlichen Europa, deren Ursprünge er insbesondere in den konfessionellen Konflikten verortet. ...
The process of electron-loss to the continuum (ELC) has been studied for the collision systems U28++H2 at a collision energy of 50 MeV/u, U28++N2 at 30 MeV/u, and U28++Xe at 50 MeV/u. The energy distributions of cusp electrons emitted at an angle of 0∘ with respect to the projectile beam were measured using a magnetic forward-angle electron spectrometer. For these collision systems far from equilibrium charge state, a significantly asymmetric cusp shape is observed. The experimental results are compared to calculations based on first-order perturbation theory, which predict an almost symmetric cusp shape. Some possible reasons for this discrepancy are discussed.
Purpose. To introduce additional methods to detect and to quantify single pathogens in the complex biofilm formation on an antibacterial dental material.
Materials and Methods. A conventional (ST) and an antibacterial dental composite (B) were manufactured. In vitro: specimens were incubated with a mixture of early colonizers. Bacterial adhesion was analyzed by TaqMan PCR after 8/24 h. In situ: TaqMan PCR and 16S rRNA Next Generation Sequencing (NGS) were performed.
Results. In vitro: after 8 h incubation, B was covered by 58.6% of the bacterial amount that was attached to ST. After 24 h, the amount of attached bacteria to ST remained constant on ST only slightly lower on B. In situ: after 8 h the amount of adhering A. viscosus and S. mitis was prominent on ST and reduced on B. NGS revealed that S. sanguinis, S. parasanguinis, and Gemella sanguinis were the mainly attached species with S. sanguinis dominant on ST and S. parasanguinis and G. sanguinis dominant on B.
Conclusions. Initial biofilm formation was altered by B. A shift between actinomycetes and streptococci was observed in situ. TaqMan PCR and 16S rRNA NGS revealed comparable results in situ and demonstrated the usefulness of NGS to characterize complex bacterial communities.
Background: Advanced non-small cell lung cancer (NSCLC) represents a significant unmet medical need. Despite advances with targeted therapies in a small subset of patients, fewer than 20% of patients survive for more than two years after diagnosis. Cancer vaccines are a promising therapeutic approach that offers the potential for durable responses through the engagement of the patient's own immune system. CV9202 is a self-adjuvanting mRNA vaccine that targets six antigens commonly expressed in NSCLC (NY ESO-1, MAGEC1, MAGEC2, 5 T4, survivin, and MUC1).
Methods/Design: The trial will assess the safety and tolerability of CV9202 vaccination combined with local radiation designed to enhance immune responses and will include patients with stage IV NSCLC and a response or stable disease after first-line chemotherapy or therapy with an EGFR tyrosine kinase inhibitor. Three histological and molecular subtypes of NSCLC will be investigated (squamous and non-squamous cell with/without EGFR mutations). All patients will receive two initial vaccinations with CV9202 prior to local radiotherapy (5 GY per day for four successive days) followed by further vaccinations until disease progression. The primary endpoint of the study is the number of patients experiencing Grade >3 treatment-related adverse events. Pharmacodynamic analyses include the assessment of immune responses to the antigens encoded by CV9202 and others not included in the panel (antigen spreading) and standard efficacy assessments.
Discussion: RNActive self-adjuvanted mRNA vaccines offer the potential for simultaneously inducing immune responses to a wide panel of antigens commonly expressed in tumors. This trial will assess the feasibility of this approach in combination with local radiotherapy in NSCLC patients.
Background: Preclinical studies demonstrate synergism between cancer immunotherapy and local radiation, enhancing anti-tumor effects and promoting immune responses. BI1361849 (CV9202) is an active cancer immunotherapeutic comprising protamine-formulated, sequence-optimized mRNA encoding six non-small cell lung cancer (NSCLC)-associated antigens (NY-ESO-1, MAGE-C1, MAGE-C2, survivin, 5T4, and MUC-1), intended to induce targeted immune responses.
Methods: We describe a phase Ib clinical trial evaluating treatment with BI1361849 combined with local radiation in 26 stage IV NSCLC patients with partial response (PR)/stable disease (SD) after standard first-line therapy. Patients were stratified into three strata (1: non-squamous NSCLC, no epidermal growth factor receptor (EGFR) mutation, PR/SD after ≥4 cycles of platinum- and pemetrexed-based treatment [n = 16]; 2: squamous NSCLC, PR/SD after ≥4 cycles of platinum-based and non-platinum compound treatment [n = 8]; 3: non-squamous NSCLC, EGFR mutation, PR/SD after ≥3 and ≤ 6 months EGFR-tyrosine kinase inhibitor (TKI) treatment [n = 2]). Patients received intradermal BI1361849, local radiation (4 × 5 Gy), then BI1361849 until disease progression. Strata 1 and 3 also had maintenance pemetrexed or continued EGFR-TKI therapy, respectively. The primary endpoint was evaluation of safety; secondary objectives included assessment of clinical efficacy (every 6 weeks during treatment) and of immune response (on Days 1 [baseline], 19 and 61).
Results: Study treatment was well tolerated; injection site reactions and flu-like symptoms were the most common BI1361849-related adverse events. Three patients had grade 3 BI1361849-related adverse events (fatigue, pyrexia); there was one grade 3 radiation-related event (dysphagia). In comparison to baseline, immunomonitoring revealed increased BI1361849 antigen-specific immune responses in the majority of patients (84%), whereby antigen-specific antibody levels were increased in 80% and functional T cells in 40% of patients, and involvement of multiple antigen specificities was evident in 52% of patients. One patient had a partial response in combination with pemetrexed maintenance, and 46.2% achieved stable disease as best overall response. Best overall response was SD in 57.7% for target lesions.
Conclusion: The results support further investigation of mRNA-based immunotherapy in NSCLC including combinations with immune checkpoint inhibitors.

An ever-increasing demand for novel antimicrobials to treat life-threatening infections caused by the global spread of multidrug-resistant bacterial pathogens stands in stark contrast to the current level of investment in their development, particularly in the fields of natural-product-derived and synthetic small molecules. New agents displaying innovative chemistry and modes of action are desperately needed worldwide to tackle the public health menace posed by antimicrobial resistance. Here, our consortium presents a strategic blueprint to substantially improve our ability to discover and develop new antibiotics. We propose both short-term and long-term solutions to overcome the most urgent limitations in the various sectors of research and funding, aiming to bridge the gap between academic, industrial and political stakeholders, and to unite interdisciplinary expertise in order to efficiently fuel the translational pipeline for the benefit of future generations.
