We performed a retrospective analysis of 100 patients with ischaemic stroke. All patients underwent intravenous thrombolysis in the acute care setting (avg. 2.8 hours, max 4.5 hours) and 10 of them also underwent mechanical thrombectomy. For 20% of the patients, the stroke was fatal. Door to needle time was 38.46 minutes. Although changes in antithrombotic treatment were introduced due to strokes, there was no significant difference in National Institute of Health Stroke Scale scores between the patients who were on antithrombotic treatment and those who were on no antithrombotic treatment.

A strongly psychosocially demanding situation in the life of a woman is the option of medically indicated abortion. Here we present the design of an ongoing study aiming to examine the stressfulness of life events related to medically indicated abortions by measuring cortisol concentrations in the participants’ hair and saliva. Pilot results show high salivary cortisol concentrations in the majority of the women one day before induced abortion. In half of the group, two months after the abortion, hair cortisol concentrations were higher in comparison to cumulative values from two months before. There were no changes in the second half.

Autoimmune adverse effects of immune checkpoint inhibitors (ICIs) are rare but may be life-threatening. We performed a retrospective analysis of the immune-related adverse effects (irAEs) of ICIs in the Masaryk Memorial Cancer Institute (MMCI) from 2011 to 2021. The ICIs were administered to 648 patients. Severe irAEs were pronounced in 83 patients (12.8 %). Further, we report a case of severe irAE after treatment with ipilimumab and nivolumab. Prednisone, mesalazine, octreotide, infliximab, vedolizumab, and mycophenolate mofetil were used to manage G4 colitis, with partial response. Early diagnosis and appropriate management of irAE are essential in the perspective of further oncological treatment.

SAP and EAT-2 are intracellular adaptor proteins that link SLAMF receptors to downstream intracellular signalling pathways. Their expression and functions vary among different types of hematopoietic cells. The roles of SAP and EAT-2 in haematological malignancies are poorly understood. Here, we attempted to optimise a method for the detection of intracellular SAP and EAT-2 by flow cytometry. We found that using PerFix EXPOSE kit for cell fixation and permeabilization ensures optimal results in terms of staining intensity and signal-to-noise ratio.
