Notwendigkeit der VerfĂĽgbarkeit nasaler Gastroskopie in der Routinediagnostik - Eine patientenorientierte Bedarfsanalyse
Für eine optimale Prävention und die Beurteilung verschiedener Krankheitsverläufe ist eine regelmäßige, ambulant durchgeführte Gastroskopie erforderlich. Diese wird am Universitätsklinikum Leipzig (UKL) als orale Gastroskopie angeboten. Dabei können die Patienten, sofern keine medizinische Kontraindikation besteht, gemäß der Leitlinie zwischen einer Untersuchung mit oder ohne Sedierung wählen.
Eine weitere Wahlmöglichkeit für die Patienten, um eine Sedierung und die damit einhergehenden Risiken zu vermeiden, stellt das Angebot der nasalen Gastroskopie dar.
Von September 2016 bis März 2017 führten wir die prospektive klinische Studie „Besteht die Notwendigkeit der Verfügbarkeit nasaler Gastroskopie in der Routinediagnostik“ in der interdisziplinären zentralen Endoskopie am UKL durch.
Konkret hatte diese Studie das Ziel, Aufschluss über den möglichen Patientenwunsch einer Wahloption der nasalen Methode unter den ambulanten Patienten des UKLs zu geben. Darüber hinaus sollte mit der Studie ermittelt werden, welche Gründe die Patienten für ihre Entscheidung angeben, ob bereits Vorerfahrungen bestehen, wie sich ggf. bestehende Vorerfahrungen auf die Entscheidung auswirken und ob die dann durchgeführte Untersuchung die Präferenz für eine zukünftige Untersuchung verändern würde.
Die nasale Gastroskopie hat sich in der durchgeführten Untersuchung als eine sichere und von Patienten gut tolerierte Alternative zur oralen Gastroskopie herausgestellt. Mit der Möglichkeit der Verminderung sedierungsassoziierter Risiken, der Senkung der anfallenden Kosten sowie der Ermöglichung einer gastroskopischen Untersuchung bei Patienten, bei denen die Durchführung der oralen Gastroskopie nicht möglich ist, könnte die nasale Gastroskopie einen großen Gewinn für die Endoskopie darstellen.:Inhaltsverzeichnis

Twenty-seventh Annual Bibliography, 2013 (Contemporary German Literature Collection)
Bibliography of contemporary German literature volumes added the previous year to Washington University Libraries\u27 Contemporary German Literature Collection. These acquisitions generally include novels, poetry, short story collections, essays, autobiographical works, and literary and cultural periodicals from publishers in Germany, Austria, and Switzerland. This Collection serves as the research arm for the Department of Germanic Languages and Literature\u27s Max Kade Center for Contemporary German Literature. This bibliography is compiled by Washington University\u27s Department of Germanic Languages and Literatures in cooperation with the University Libraries.

Streamlined Lensed Quasar Identification in Multiband Images via Ensemble Networks
Quasars experiencing strong lensing offer unique viewpoints on subjects
related to the cosmic expansion rate, the dark matter profile within the
foreground deflectors, and the quasar host galaxies. Unfortunately, identifying
them in astronomical images is challenging since they are overwhelmed by the
abundance of non-lenses. To address this, we have developed a novel approach by
ensembling cutting-edge convolutional networks (CNNs) -- for instance, ResNet,
Inception, NASNet, MobileNet, EfficientNet, and RegNet -- along with vision
transformers (ViTs) trained on realistic galaxy-quasar lens simulations based
on the Hyper Suprime-Cam (HSC) multiband images. While the individual model
exhibits remarkable performance when evaluated against the test dataset,
achieving an area under the receiver operating characteristic curve of 97.3%
and a median false positive rate of 3.6%, it struggles to generalize in real
data, indicated by numerous spurious sources picked by each classifier. A
significant improvement is achieved by averaging these CNNs and ViTs, resulting
in the impurities being downsized by factors up to 50. Subsequently, combining
the HSC images with the UKIRT, VISTA, and unWISE data, we retrieve
approximately 60 million sources as parent samples and reduce this to 892,609
after employing a photometry preselection to discover lensed quasars
with Einstein radii of arcsec. Afterward, the ensemble
classifier indicates 3080 sources with a high probability of being lenses, for
which we visually inspect, yielding 210 prevailing candidates awaiting
spectroscopic confirmation. These outcomes suggest that automated deep learning
pipelines hold great potential in effectively detecting strong lenses in vast
datasets with minimal manual visual inspection involved.Comment: Accepted for publication in the Astronomy & Astrophysics journal. 28

Ambient and substrate energy influence decomposer diversity differentially across trophic levels
The species-energy hypothesis predicts increasing biodiversity with increasing energy in ecosystems. Proxies for energy availability are often grouped into ambient energy (i.e., solar radiation) and substrate energy (i.e., non-structural carbohydrates or nutritional content). The relative importance of substrate energy is thought to decrease with increasing trophic level from primary consumers to predators, with reciprocal effects of ambient energy. Yet, empirical tests are lacking. We compiled data on 332,557 deadwood-inhabiting beetles of 901 species reared from wood of 49 tree species across Europe. Using host-phylogeny-controlled models, we show that the relative importance of substrate energy versus ambient energy decreases with increasing trophic levels: the diversity of zoophagous and mycetophagous beetles was determined by ambient energy, while non-structural carbohydrate content in woody tissues determined that of xylophagous beetles. Our study thus overall supports the species-energy hypothesis and specifies that the relative importance of ambient temperature increases with increasing trophic level with opposite effects for substrate energy
