in English, German Dies ist das sechzehnte Kapitel der von der Paul-Ehrlich-Gesellschaft für Chemotherapie e.V. (PEG) herausgegebenen S2k Leitlinie „Kalkulierte parenterale Initialtherapie bakterieller Erkrankungen bei Erwachsenen – Update 2018“ in der 2. aktualisierten Fassung.Infektionen durch resistente gramnegative Erreger sind eine Herausforderung. In diesem Kapitel werden Therapieempfehlungen für die gezielte Therapie von Infektionen durch ESBL-bildende Enterobacteriaceae, Carbapenemase-bildende Enterobactaeriaceae und Carbapenem-resistente Acinetobacter baumannii gegeben, die auf der begrenzten verfügbaren Evidenz beruhen.in English, German Dies ist das siebzehnte Kapitel der von der Paul-Ehrlich-Gesellschaft für Chemotherapie e.V. (PEG) herausgegebenen S2k Leitlinie „Kalkulierte parenterale Initialtherapie bakterieller Erkrankungen bei Erwachsenen – Update 2018“ in der 2. aktualisierten Fassung.Dieses Kapitel setzt sich mit den ökonomischen Effekten der antiinfektiven Therapie auseinander. Jede Behandlungsentscheidung ist auch eine kostenrelevante Entscheidung. Die Autoren beleuchten insbesondere die Frage, ob es Evidenz dafür gibt, das klinische wirksame Strategien auch ökonomisch günstig sind. Unter anderem werden Antibiotic Stewardship Programme (ABS), Leitlinienadhärenz in der Initialtherapie, De-Eskalation, Sequenztherapie sowie das therapeutische Drug Monitoring. Ökonomisch günstig sind sowohl direkte Kosteneinsparungen als auch die Verkürzung der Verweildauer um Ressourcen schneller wieder bereit zu stellen.Mounting evidence indicates that the vagina can harbor uropathogenic bacteria. Here, we consider three roles played by the vagina and its bacterial inhabitants in urinary tract infection (UTI) and urinary health. First, the vagina can serve as a reservoir for Escherichia coli, the most common cause of UTI, and other recognized uropathogens. Second, several vaginal bacterial species are frequently detected upon urine culture but are underappreciated as uropathogens, and other vaginal species are likely under-reported because of their fastidious nature. Third, some vaginal bacteria that are not widely viewed as uropathogens can transit briefly in the urinary tract, cause injury or immunomodulation, and shift the balance of host-pathogen interactions to influence the outcomes of uropathogenesis. This chapter describes the current literature in these three areas and summarizes the impact of the vaginal microbiota on susceptibility to UTI and other urologic conditions.

It was developed by dermatologists, virologists, ophthalmologists, ENT physicians, neurologists, pediatrician and anesthetists using a formal consensus process (S2k).The guideline provides an overview of clinical and molecular diagnostics as well as antigen detection, antibody culture and viral culture. Diagnostic special situations and complicated courses of the disease are also considered. The antiviral therapy of zoster and postzoster neuralgia is presented in general and for special situations. Detailed information on the treatment of pain is mentioned and presented in an overview. Likewise, the local therapeutic measures are discussed.

Considering the continued search for new DES - especially those that exemplify the aforementioned characteristics, we report the preparation of DES based on natural analogues of l-ascorbic acid for the first time. check details The onset of eutectic melting occurred at temperatures far below the melting point of the individual components and resulted in the generation of glass forming fluids with glass transition temperatures, viscosities and flow behavior that are comparable to similar systems. This work expands the current array of DES that can be produced using naturally occurring components, which given their potential to be bio-derived, interesting physicochemical properties (e. g. propensity to supercool and vitrify) and apparent antibacterial nature, may provide utility within a range of applications. © 2020 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.We have recently developed a computational methodology to separate the effects of size, composition, symmetry and fluxionality in explaining the experimental photoelectron spectra of mixed-metal clusters. This methodology was successfully applied first in explaining the observed differences between the spectra of Al13 - and Al12Ni- and more recently to explain the measured spectra of AlnMo-, n=3-5,7 clusters. The combination of our approach and new synthesis techniques can be used to prepare cluster-based materials with tunable properties. In this work we use the methodology to predict the spectrum of Al6Mo-. This system was chosen because its neutral counterpart is a perfect octahedron and it is distorted to a D3d symmetry and was not observed in the recent experiments. This high symmetry cluster bridges the less symmetric Al5Mo- and Al7Mo-structures.The measured spectra of Al5Mo- has well defined peaks, while that of Al7Mo-does not. This can be explained by the fluxionality of Al7Mo-, as at least 6 different structures lie within the range that can be reached by thermal effects. We predict that Al6Mo- has well defined peaks, but some broadening is expected as there are two low-lying isomers, one of D3d and the second of D3h symmetry that are only 0.052 eV apart. © 2020 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.Azobenzene is one of the most studied light-controlled molecular switches and it has been incorporated in a large variety of supramolecular systems to control their structural and functional properties. Given the peculiar isomeric distribution at the photoexcited state (PSS), azobenzene derivatives have been used as photoactive framework to build metastable supramolecular systems that are out of the thermodynamic equilibrium. This could be achieved exploiting the peculiar E/Z photoisomerization process that can lead to isomeric ratios that are unreachable in thermal equilibrium conditions. The challenge in the field is to find molecular architectures that, under given external circumstances, lead to a given isomeric ratio in a reversible and predictable manner, ensuring an ultimate control of the configurational distribution and system composition. By reviewing early and recent works in the field, this review aims at describing photoswitchable systems that, containing an azobenzene dye, display a controlled configurational equilibrium by means of a molecular recognition event.
