    Abstract Posterior circulation stroke (PCS), caused by infarction within the vertebrobasilar arterial system, is a potentially life-threatening condition and accounts for about 20-25% of all ischemic strokes. Diagnosing PCS can be challenging due to the vast area of brain tissue supplied by the posterior circulation and, as a consequence, the wide range of-frequently non-specific-symptoms. Commonly used prehospital stroke scales and triage systems do not adequately represent signs and symptoms of PCS, which may also escape detection by cerebral imaging. All these factors may contribute to causing delay in recognition and diagnosis of PCS in the emergency context. This narrative review approaches the issue of diagnostic error in PCS from different perspectives, including anatomical and demographic considerations as well as pitfalls and problems associated with various stages of prehospital and emergency department assessment. Strategies and approaches to improve speed and accuracy of recognition and early management of PCS are outlined.

    Abstract Ferrocene and its derivatives have fascinated chemists for more than 70 years, not least due to the analogies with the properties of benzene. Despite these similarities, the obvious difference between benzene and ferrocene is the presence of an iron ion and hence the availability of d-orbitals for properties and reactivity. Phenylnitrene with its rich photochemistry can be considered an analogue of nitrenoferrocene. As with most organic and inorganic nitrenes, nitrenoferrocene can be obtained by irradiating the azide precursor. We study the photophysical and photochemical processes of dinitrogen release from 1,1'-diazidoferrocene to form 1-azido-1'-nitrenoferrocene with UV-pump-mid-IR-probe transient absorption spectroscopy and time-dependent density functional theory calculations including spin-orbit coupling. An intermediate with a bent azide moiety is identified that is pre-organised for dinitrogen release

    Titelübersetzung Stillraten während der COVID-19-Pandemie in Deutschland: Daten aus dem CRONOS-Register.
    Abstract SARS-CoV-2 infection and COVID-19 disease are thought to have an impact on breastfeeding rate - besides other known peripartal issues. Data of the national CRONOS registry regarding breastfeeding behavior in 6,746 women was analyzed regarding the time window between maternal SARS-CoV-2 infection and time of delivery. In addition, other influencing factors like the predominant viral variant, maternal disease severity, and gestational age at delivery were taken into account. Our data suggest that within the variables analyzed, in the case of acute maternal infection (<14 days before birth), breastfeeding behavior improved with increasing gestational age at birth (p<0.0001), with less severe maternal illness (p<0.0001) and as the pandemic progressed with less virulent viral variants (p=0.01). When adjusting for COVID-19-associated and non-associated factors, rooming-in remains the most important factor positively influencing breastfeeding behavior. With regards to the benefits for mother and infants from breastfeeding, a separation of mother and child even in case of infectious settings should be avoided.

    Titelübersetzung Potential Impact of Public Communication on Emergency Presentations due to Headache during the Covid-19 Pandemic.
    Abstract Headache is a frequent presenting symptom in the emergency department. While most cases are of benign aetiology, it is crucially important to identify potentially dangerous underlying disorders. We hypothesized an increase in headache-related emergency presentations after venous thrombosis of cerebral sinuses had been identified as a rare side effect of vaccination with adenovirus vector-based Coronavirus-disease 2019 (COVID-19) vaccines and that information had been publicly communicated by the Paul Ehrlich Institute. Data from patients with the diagnosis of primary headache disorders or unspecified headache presenting to the Interdisciplinary Emergency Department of the University Medicine Mannheim were retrospectively analysed. Based on vaccination dashboard data published by the Federal Ministry of Health, calendar weeks 14-30 and 47-48, on the one hand, and 1-13 and 31-46, on the othe, were categorized into a variable "vaccination epoch" (14-30, 47-48: high vaccination activity if≥3 million weekly vaccinations in Germany; 1-13, 31-46: low vaccination activity if<3 million weekly vaccinations). The number of patients with headache was the dependent variable. A Poisson regression was performed to analyze whether the frequency of events, i. e., patient presentations, was a function of year (2019, 2021), epoch (high, low) and an interaction of year and epoch - the latter reflecting an impact of vaccination activity during the pandemic and expressed as incidence rate ratio. Compared to 2019, there was a more than 70% increase in presentations due to headache during periods of high vaccination activity in 2021 (p<0.001; 95% confidence interval 1.272-2.316), in 25% of presentations in 2021, patients considered their headache as vaccination-associated. Public communication and resulting nocebo effects may, among other factors, have contributed to our observation of increased numbers of emergency headache presentations, illustrating the impact of public distribution of medical information on practical aspects of emergency care during crises.
