PTF1J2224+17: a short-period, high-field polar

We present time-resolved photometry of the cataclysmic variable (CV) PTF1J2224+17 obtained during 4 nights in October 2018 and January 2019 from Inastars observatory. The object is variable on a period of 103.82 min. Archival Catalina Real-Time Transient Survey (CRTS), PTF, and ZTF-data show frequent changes between high and low states. Based on its photometric properties and the cyclotron humps in the identification spectrum the object is certainly classified as an AM Herculis star (or polar) with a likely magnetic field strength of B ~ 65 MG. Its accretion duty cycle was estimated from nine years of photometric monitoring to be about 35 %.Comment: AN, in press (7 pages, 6 figures

Prognostic value of ‘late’ electroencephalography recordings in patients with cardiopulmonal resuscitation after cardiac arrest

Background: Electroencephalography (EEG) significantly contributes to the neuroprognostication after resuscitation from cardiac arrest. Recent studies suggest that the prognostic value of EEG is highest for continuous recording within the first days after cardiac arrest. Early continuous EEG, however, is not available in all hospitals. In this observational study, we sought to evaluate the predictive value of a 'late' EEG recording 5-14 days after cardiac arrest without sedatives. Methods: We retrospectively analyzed EEG data in consecutive adult patients treated at the medical intensive care units (ICU) of the Charite-Universitatsmedizin Berlin. Outcome was assessed as cerebral performance category (CPC) at discharge from ICU, with an unfavorable outcome being defined as CPC 4 and 5. Results: In 187 patients, a 'late' EEG recording was performed. Of these patients, 127 were without continuous administration of sedative agents for at least 24 h before the EEG recording. In this patient group, a continuously suppressed background activity < 10 mu V predicted an unfavorable outcome with a sensitivity of 31% (95% confidence interval (CI) 20-45) and a specificity of 99% (95% CI 91-100). In patients with suppressed background activity and generalized periodic discharges, sensitivity was 15% (95% CI 7-27) and specificity was 100% (95% CI 94-100). GPDs on unsuppressed background activity were associated with a sensitivity of 42% (95% CI 29-46) and a specificity of 92% (95% CI 82-97). Conclusions: A 'late' EEG performed 5 to 14 days after resuscitation from cardiac arrest can aide in prognosticating functional outcome. A suppressed EEG background activity in this time period indicates poor outcome
