INVESTORSʼ REACTIONS FOR SUSTAINABILITY INDEX INCLUSION – IS CSR A GOOD NEWS?

This article presents the problem of measuring the impact of information disclosure aboutCSR activities on stock performance. The research was performed on two indexes which representPan-European capital market and local Central and Eastern European capital market. Differentmarket characteristics could limit the application of results presented in numerous studiesperformed on well-established markets. The information with relatively strong signal for investoris the inclusion to CSR index. In order to measure the investors’ reaction the event study analysiswas performed. It was proved that the short–term reaction was very similar on each market. Thereaction to announcement of CSR index inclusion was slightly negative, but this effect was offsetby the opposite reaction in the day of inclusion. The total reaction in the seven days event windowwas close to zero. However, the long-term reaction measured in 30 trading days window wasnegative for two markets, but the local market investors show more discontent

Mechanical thrombectomy in acute stroke – Five years of experience in Poland

Objectives Mechanical thrombectomy (MT) is not reimbursed by the Polish public health system. We present a description of 5 years of experience with MT in acute stroke in Comprehensive Stroke Centers (CSCs) in Poland. Methods and results We retrospectively analyzed the results of a structured questionnaire from 23 out of 25 identified CSCs and 22 data sets that include 61 clinical, radiological and outcome measures. Results Most of the CSCs (74%) were founded at University Hospitals and most (65.2%) work round the clock. In 78.3% of them, the working teams are composed of neurologists and neuro-radiologists. All CSCs perform CT and angio-CT before MT. In total 586 patients were subjected to MT and data from 531 of them were analyzed. Mean time laps from stroke onset to groin puncture was 250±99min. 90.3% of the studied patients had MT within 6h from stroke onset; 59.3% of them were treated with IV rt-PA prior to MT; 15.1% had IA rt-PA during MT and 4.7% – emergent stenting of a large vessel. M1 of MCA was occluded in 47.8% of cases. The Solitaire device was used in 53% of cases. Successful recanalization (TICI2b–TICI3) was achieved in 64.6% of cases and 53.4% of patients did not experience hemorrhagic transformation. Clinical improvement on discharge was noticed in 53.7% of cases, futile recanalization – in 30.7%, mRS of 0–2 – in 31.4% and mRS of 6 in 22% of cases. Conclusion Our results can help harmonize standards for MT in Poland according to international guidelines
