Der Vorstand der Deutschen Gesellschaft für Epileptologie und die Kommission „Epilepsie und Synkopen“ der Deutschen Gesellschaft für Neurologie haben die aktuelle Datenlage zur Impfung zur Vorbeugung der Corona-Virus-Krankheit 2019 (COVID-19) sowie zur Impfpriorisierung bei Menschen mit Epilepsie gesichtet, diese zusammengefasst und geben die unten genannten Empfehlungen ab.
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.
The Board of Directors of the German Society of Epileptology and the committee on epilepsy and syncope of the German Society of Neurology have reviewed the current data on vaccination to prevent coronavirus disease 2019 (COVID-19) and vaccination prioritization in people with epilepsy and provide a summary and recommendations.
Background: Efficacy of treatment after failure of check point inhibitors (ICI) therapy remains ill-defined in metastatic renal cell carcinoma (mRCC).
Objective: To evaluate the safety and effectiveness of cabozantinib after failure of ICI-based therapies.
Design, setting and participants: Patients with mRCC who concluded cabozantinib treatment directly after an ICI-based therapy were eligible. Data was collected retrospectively from participating sites in Germany.
Interventions: Cabozantinib was administered as a standard of care.
Outcome measurements and statistical analysis
Adverse events (AE) were reported according to CTCAE v5.0. Objective response rate according to RECIST 1.1 and Progression Free Survival (PFS) were collected from medical records. Descriptive statistics and Kaplan-Meyer-plots were utilized.
Results and limitations: About 56 eligible patients (71.4% male) with median age of 66 years and clear cell histology in 66.1% (n = 37) were analyzed. 87.5% (n = 49) had ≥ 2 previous lines. IMDC risk was intermediate or poor in 17 patients (30.4%) and missing in 66.1%. 20 patients (35.7%) started with 60 mg. 55.4% (n = 31) required dose reductions, 26.8% (n = 15) treatment delays and 1.8% (n = 1) treatment discontinuation. Partial response was reported in 10.7% (n = 6), stable and progressive disease were reported in 19.6% (n = 11) and in 12.5% (n = 7). 32 patients were not evaluable (57.1%). Median treatment duration was 6.1 months. Treatment related AE were reported in 76.8% (n = 43) and 19.6% (n = 11) had grade 3-5. Fatigue (26.8%), diarrhea (26.8%) and hand-foot-syndrome (25.0%) were the 3 most frequent AEs of any grade and causality. SAE were reported in 21.4% (n = 12), 2 were fatal. Major limitation was the retrospective data capture in our study.
Conclusions: Cabozantinib followed directly after ICI-based therapy was safe and feasible. No new safety signals were reported. A lower starting dose was frequently utilized in this real-world cohort, which was associated with a favorable tolerability profile. Our data supports the use of cabozantinib after ICI treatment.
Biogenic organic precursors play an important role in atmospheric new particle formation (NPF). One of the major precursor species is α-pinene, which upon oxidation can form a suite of products covering a wide range of volatilities. Highly oxygenated organic molecules (HOMs) comprise a fraction of the oxidation products formed. While it is known that HOMs contribute to secondary organic aerosol (SOA) formation, including NPF, they have not been well studied in newly formed particles due to their very low mass concentrations. Here we present gas- and particle-phase chemical composition data from experimental studies of α-pinene oxidation, including in the presence of isoprene, at temperatures (−50 and −30 ∘C) and relative humidities (20 % and 60 %) relevant in the upper free troposphere. The measurements took place at the CERN Cosmics Leaving Outdoor Droplets (CLOUD) chamber. The particle chemical composition was analyzed by a thermal desorption differential mobility analyzer (TD-DMA) coupled to a nitrate chemical ionization–atmospheric pressure interface–time-of-flight (CI-APi-TOF) mass spectrometer. CI-APi-TOF was used for particle- and gas-phase measurements, applying the same ionization and detection scheme. Our measurements revealed the presence of C8−10 monomers and C18−20 dimers as the major compounds in the particles (diameter up to ∼ 100 nm). Particularly, for the system with isoprene added, C5 (C5H10O5−7) and C15 compounds (C15H24O5−10) were detected. This observation is consistent with the previously observed formation of such compounds in the gas phase. However, although the C5 and C15 compounds do not easily nucleate, our measurements indicate that they can still contribute to the particle growth at free tropospheric conditions. For the experiments reported here, most likely isoprene oxidation products enhance the growth of particles larger than 15 nm. Additionally, we report on the nucleation rates measured at 1.7 nm (J1.7 nm) and compared with previous studies, we found lower J1.7 nm values, very likely due to the higher α-pinene and ozone mixing ratios used in the present study.
