| 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 | 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. |

| 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 |

| Abstract | As a clinical model of hippocampal dysfunction, transient global amnesia (TGA) causes reversible memory disturbance. While episodic memory deficits in TGA patients have been extensively described, data regarding semantic memory involvement are sparse and contradictory. We report impaired semantic fluency performance in 16 patients with hippocampal lesions on MRI during acute TGA compared to their performance one day later and to that of 20 healthy subjects. Our findings support the involvement of the hippocampus in semantic retrieval. |

| Abstract | Introduction: Physically or emotionally charged events have consistently been reported as precipitating an episode of transient global amnesia (TGA). In conjunction with evidence of hippocampal involvement from neuroimaging, this has promoted the hypothesis that TGA is a stress-related disorder. Methods: In this retrospective observational study, medical records of 389 patients with TGA were analysed regarding documented precipitating events, which were classified according to previously suggested criteria. Moreover, comorbidities and results of magnetic resonance imaging were collected. Findings: In our cohort of TGA patients, 231 were female (59.4%). A precipitating factor was identified in 266 patients (68.4%). Of these, 136 patients (51.1%) reported physical triggers, the most common being physical exertion (64.0%). Another 122 patients (45.9%) presented with an emotional trigger, most frequently classified as an interpersonal conflict (42.7%). In 8 cases (2.1%), TGA was preceded by a medical procedure. Emotional triggers were more often experienced by women (37.2% vs 22.8%, p = 0.003), while physical stressors were more often present in men (30.7% vs 41.1%, p = 0.035). Women had a significantly higher number of hippocampal MRI lesions than men (mean 1.13 vs 0.92; p = 0.042). Conclusion: Our data suggest a female predominance in TGA occurrence and a sex-related difference in susceptibility to certain triggering events in TGA patients. In light of recent research on sex-specific differences in vulnerability to stress, these findings support the hypothesis that this might be a significant contributing factor in the pathogenesis of TGA. |
