National and International Comparisons of Gynecological Research in Germany Based on a Bibliometric Analysis of Publications.

Background: Recent years have seen a considerable shift from male doctors to female doctors in the field of gynecology. Female doctors are traditionally more involved with planning and maintaining their family. For gynecology, this could be associated with a risk that research activities will decrease, particularly if results are published in scientific journals. Methods: In view of this shift, a comparative observational study was carried for 2022 in which 1306 publications were matched to 1786 female and male doctors reported on the websites of the 44 locations of university gynecology departments in Germany. In addition, the volume of publications issued between 2014 and 2022 was compared for Germany, France, the United Kingdom, and the United States. In Germany, the volume of publications in Gynecology was additionally compared with the publication outputs of the specialties Urology and Trauma Surgery. Results: Since 2014, the increase in the numbers of publications in the field of Gynecology in Germany was lower (225%) than that of the countries with which it was compared (238%/252%/260% for F/UK/USA). When Gynecology was compared with other medical specialties in Germany, the number of publications in Urology were found to have increased at a lower rate (196%) while the number of publications in the field of Trauma Surgery increased by more (286%) than that of Gynecology. At the start of 2023, the percentage of women who were working as doctors at the lowest hierarchical level (junior doctor) was 81%. The publication output per capita of female doctors working at lower levels in the medical hierarchy, i.e., working as junior doctors and senior physicians, was between 40% and 80% lower than that of male doctors working at the same level. However, female directors published as much as male directors did. In the lower hierarchy levels, men were up to 14% more likely to be without an academic title. Predictors for more extensive publication activities by young female and male doctors include the extent and quality of publications by doctors in senior positions, the presence of a comprehensive cancer center or an institute for human genetics at the location where the young doctors were working, and joint publications with foreign authors. Conclusion: For the German Society of Gynecology and Obstetrics, the results suggest a number of approaches to promote young researchers. The support provided to young female doctors is especially important as this should help to retain them as junior researchers over the long term.

Electrolysis in reduced gravitational environments: current research perspectives and future applications.

Electrochemical energy conversion technologies play a crucial role in space missions, for example, in the Environmental Control and Life Support System (ECLSS) on the International Space Station (ISS). They are also vitally important for future long-term space travel for oxygen, fuel and chemical production, where a re-supply of resources from Earth is not possible. Here, we provide an overview of currently existing electrolytic energy conversion technologies for space applications such as proton exchange membrane (PEM) and alkaline electrolyzer systems. We discuss the governing interfacial processes in these devices influenced by reduced gravitation and provide an outlook on future applications of electrolysis systems in, e.g., in-situ resource utilization (ISRU) technologies. A perspective of computational modelling to predict the impact of the reduced gravitational environment on governing electrochemical processes is also discussed and experimental suggestions to better understand efficiency-impacting processes such as gas bubble formation and detachment in reduced gravitational environments are outlined.

Operando tracking of oxidation-state changes by coupling electrochemistry with time-resolved X-ray absorption spectroscopy demonstrated for water oxidation by a cobalt-based catalyst film.

Transition metal oxides are promising electrocatalysts for water oxidation, i.e., the oxygen evolution reaction (OER), which is critical in electrochemical production of non-fossil fuels. The involvement of oxidation state changes of the metal in OER electrocatalysis is increasingly recognized in the literature. Tracing these oxidation states under operation conditions could provide relevant information for performance optimization and development of durable catalysts, but further methodical developments are needed. Here, we propose a strategy to use single-energy X-ray absorption spectroscopy for monitoring metal oxidation-state changes during OER operation with millisecond time resolution. The procedure to obtain time-resolved oxidation state values, using two calibration curves, is explained in detail. We demonstrate the significance of this approach as well as possible sources of data misinterpretation. We conclude that the combination of X-ray absorption spectroscopy with electrochemical techniques allows us to investigate the kinetics of redox transitions and to distinguish the catalytic current from the redox current. Tracking of the oxidation state changes of Co ions in electrodeposited oxide films during cyclic voltammetry in neutral pH electrolyte serves as a proof of principle.

Electromodified NiFe Alloys as Electrocatalysts for Water Oxidation: Mechanistic Implications of Time-Resolved UV/Vis Tracking of Oxidation State Changes.

Facile electromodification of metallic NiFe alloys leads to a series of NiFe oxyhydroxide surface films with excellent electrocatalytic performance in alkaline water oxidation. During cyclic voltammetry and after sudden potential jumps between noncatalytic and catalytic potentials, Ni oxidation/reduction was tracked with millisecond time resolution by a UV/Vis reflectance signal. Optimal catalysis at intermediate Ni/Fe ratios is explained by two opposing trends for increasing Fe content: a) pronounced slowdown of the Ni2+ /Ni3+ oxidation step and b) increased reactivity of the most oxidized catalyst state detectable at catalytic potentials. This state may involve an equilibrium between Ni4+ ions and Ni2+ ions with neighboring ligand holes, possibly in the form of bound peroxides.

Facile Formation of Nanostructured Manganese Oxide Films as High-Performance Catalysts for the Oxygen Evolution Reaction.

The development of inexpensive, earth abundant, and bioinspired oxygen evolution electrocatalysts that are easily accessible and scalable is a principal requirement with regard to the feasibility of water splitting for large-scale chemical energy storage. A unique, versatile, and scalable approach has been developed to fabricate manganese oxide films from single layers to multilayers with a controlled thickness and high reproducibility. The produced MnOx films are composed of small nanostructures that are assembled closely in the form of porous sponge-like layers. The films were investigated for the electrochemical oxygen evolution reaction in alkaline media and demonstrate a remarkable activity as well as a superior stability of over 60 h. To elucidate the catalytically active species, as well as the striking structural characteristics, the films were further examined in depth by using SEM, TEM, and X-ray photoelectron spectroscopy, as well as quasi in situ extended X-ray absorption fine structure and X-ray absorption near edge structure analysis. The MnOx catalyst films excel because of a favorably high fraction of Mn3+ ions that are retained even after operation at oxidizing potentials. Upon exposure to oxidizing potentials in strongly alkaline aqueous electrolyte, the catalyst material maintains its structural integrity at the nanostructural, morphological, and atomic level.

Spectroscopic identification of active sites for the oxygen evolution reaction on iron-cobalt oxides.

The emergence of disordered metal oxides as electrocatalysts for the oxygen evolution reaction and reports of amorphization of crystalline materials during electrocatalysis reveal a need for robust structural models for this class of materials. Here we apply a combination of low-temperature X-ray absorption spectroscopy and time-resolved in situ X-ray absorption spectroelectrochemistry to analyze the structure and electrochemical properties of a series of disordered iron-cobalt oxides. We identify a composition-dependent distribution of di-µ-oxo bridged cobalt-cobalt, di-µ-oxo bridged cobalt-iron and corner-sharing cobalt structural motifs in the composition series. Comparison of the structural model with (spectro)electrochemical data reveals relationships across the composition series that enable unprecedented assignment of voltammetric redox processes to specific structural motifs. We confirm that oxygen evolution occurs at two distinct reaction sites, di-µ-oxo bridged cobalt-cobalt and di-µ-oxo bridged iron-cobalt sites, and identify direct and indirect modes-of-action for iron ions in the mixed-metal compositions.

The emergency data set for the German Electronic Health Card--which benefits can be expected?

BACKGROUND: In order to improve access to pre-existing patient information in case of emergency, the German Electronic Health Card (EHC) is supposed to hold emergency data. As a basis, the German Medical Association developed an emergency data set, which provides the possibility to store information on prior diagnoses, medications, allergies and other emergency-relevant information. OBJECTIVES: One main objective of the study is to evaluate the usefulness of the emergency data in specific emergency situations. METHODS: Within a two-phase exploratory study, a total of 64 paper-based emergency data sets were completed by primary care physicians, and then were evaluated by clinicians, emergency physicians, and paramedics. RESULTS: Clinicians, emergency physicians as well as paramedics rated the emergency data set in more than 70% of the reviewed cases as very useful or useful. The greatest benefit was attributed to the information on diagnoses and medication. CONCLUSION: The implementation of an emergency data on the EHC has the potential to improve safety, quality and efficiency of emergency care.

[Cross-sectoral quality assurance in ambulatory care]. / Sektorenübergreifende Qualitätssicherung in der ambulanten Versorgung.

Overcoming rigid sectoral segmentation in healthcare has also become a health policy target in quality assurance. With the Act to Enhance Competition in Statutory Health Insurance (GKV-WSG) coming into effect, quality assurance measures are to be designed in a cross-sectoral fashion for in- and outpatient sectors equally. An independent institution is currently mandated to develop specific quality indicators for eleven indications. For three of these operating tests have already been commissioned by the Federal Joint Committee. This article depicts the major results of a feasibility study, including a compliance cost estimate, for the aforementioned indications of cross-sectoral quality assurance (cQA). In conclusion, a number of both practical and conceptual basic challenges are still to be resolved prior to the full implementation of cQA, such as a sufficient specification to activate documentation requirements and an inspection system capable of separating actual quality problems from documentary deficits. So far, a comprehensive cost-utility analysis of cQA has not been provided, in particular with comparison to existing QA systems. In order to optimise cost and utility of cQA an evidence-based approach is required for both the extension of cQA areas and for QA provisions.

2-Amino-terephthalic acid N,N-dimethyl-formamide disolvate.

The asymmetric unit of the title structure, C(8)H(7)NO(4)·2C(3)H(7)NO, contains one 2-amino-terephthalic acid and two N,N-dimethyl-formamide mol-ecules. Strong O-H⋯O hydrogen bonds between the acidic carb-oxy H atoms of 2-am-ino-terephthalic acid and the O atoms of both solvent mol-ecules form linear 1:2 complex units. One H atom of the amine group is involved in intra-molecular N-H⋯O hydrogen bonding, whereas the second one takes part in an inter-molecular N-H⋯O connection. Furthermore, the crystal is stabilized by weak C-H⋯O hydrogen bonds.
