Abstract
INTRODUCTION COVID-19 is considered a respiratory virosis in its classic form, although it may present with heterogeneous symptoms. Thoracic complications occur in a small percentage of patients. Our objective was to evaluate existing experience with this disease and its thoracic manifestations and to determine the real-world status of care of these patients. METHODS This study is a retrospective, single-institution analysis of a group of patients hospitalized with acute and post-acute COVID-19 pneumonia at Thomayer Hospital in Prague in the period from December 2020 to March 2022 and indicated for a thoracic surgical procedure. RESULTS During the peak of COVID-19 pandemic, a thoracic intervention was performed in 46 admitted patients. Thoracic drainage (due to pneumothorax in 18 cases, fluidothorax in 3 cases, CT-guided lung abscess drainage in 2 cases, and CT-guided pneumatocele drainage in 2 cases) were the most common thoracic surgical procedures. Pleurectomy/decortication surgery was done in 10 cases. Additionally, 12 lung parenchyma-sparing resections were performed, while lobectomy was required in 2 cases. Resection of postintubation tracheal stenosis due to a severe course of COVID-19 pneumonia was indicated in 2 patients. CONCLUSION Even mild COVID-19 may cause a considerable morphological a functional alteration of the respiratory system. The most common complications of COVID-19 pneumonia that require a thoracic surgical intervention include pathologies associated with an air leak and accumulation of air (pneumothorax, pneumomediastinum and subcutaneous emphysema). The development of pulmonary necrosis, symptomatic bronchiectasis, pneumatocele, and bullous-fibrotic formations may result in pneumothorax, hemothorax or thoracic empyema in sporadic cases. An early thoracic surgical intervention to treat thoracic complications of COVID-19 pneumonia can improve the survival of COVID-19 patients.

Abstract
The present nuclear and cell body diameter measurements demonstrated size differences of the approximate cell space estimate occupied by the cell nucleus during the cell differentiation in lymphocytic, granulocytic and erythroid cell lineages. These lineages were used as convenient models because all differentiation steps were easily identified and accessible in diagnostic peripheral blood or bone marrow smears of blood donors (BDs), patients suffering from chronic lymphocytic leukemia (CLL), patients with chronic myeloid leukemia (CML) and refractory anemia (RA) of the myelodysplastic syndrome (MDS). The cell space occupied by the nucleus was constant and did not change during the cell differentiation in the lymphocytic cell lineages of BDs and CLL patients despite the decreased cell size. In contrary, the cell space occupied by the nucleus markedly decreased in differentiating cells of granulocytic and erythroid lineages of patients suffering from CML. In the erythroid cell lineage in patients with RA of MDS the small reduction of the cell space occupied by the nucleus during the differentiation was not significant. The measurements also indicated that in progenitor cells of all studied cell lineages nuclei occupied more than 70 % of the cell space. Thus, the nucleus-cytoplasmic morphological and functional equilibrium appeared to be characteristic for each differentiation step and each specific cell lineage.

Abstract
Aim:To prove the clinical effect rTMS neuronavigation vs. standard coil positioning vs. controlls in the therapy of madication-resistant auditory hallucinations.Materials and methods:10 patients with medication-resistant auditory hallucinations on stabile antipsychotic medication, examined by MRI, PET, then treated by 1) neuronavigated, 2) standard positioning and 3) sham rTMS (controlls).Double-blind randomized sham-controlled parallel design was used in the study.rTMS parameters: 0.9Hz, 100%MT, 1080 pulses/session, 10 rTMS sessions within 2 weeks:1.Neuronavigated rTMS: coil focused over the highest contrast of metabolic activity in the left temporo-parietal (T-P) area (according to the SPM analyse 18FDG PET data).2.Standard rTMS: coil administered over the left T-P region defined as the midway between the T3 and P3 sites according to the international 10/20 EEG electrode system.3.Sham: coil angled 90° away from the skullPsychometric measurement: PANSS, Hallucination Change Scale (HCS) and the Auditory Hallucination rating scale (AHRS).Results and conclusion:Confirmation of a significant decrease in the Hallucination item as well as in the total of the positive score of PANSS, HCS and AHRS. Sham rTMS did not show a trend for improvement over time. Between-group comparisons of AHRS scores revealed significant differences, which confirmed efficiency of using neuronavigated rTMS.Compared to standard positioning in future studies, we believe to find rTMS neuronavigation more precise and effective. Studies monitoring a continuing effect of rTMS over long time periods are needed.Supported by the CNS, MZČ;R MZ0PCP2005 and MŠMT 1M0517, VZ 00 216 208 16.

Abstract
BACKGROUND The EUMDS registry is an unique prospective, longitudinal observational registry enrolling newly diagnosed patients with lower-risk myelodysplastic syndrome (MDS) from 17 European countries from both university hospitals and smaller regional hospitals. OBJECTIVE The aim of this study was to describe the usage and clinical impact of erythropoiesis-stimulating agents (ESAs) in 1696 patients enrolled between 2008 and 2014. METHODS The effects of ESAs on outcomes were assessed using proportional hazards models weighting observations by propensity to receive ESA treatment within a subset of anaemic patients with or without a regular transfusion need. RESULTS ESA treatment (median duration of 27.5 months, range 0-77 months) was administered to 773 patients (45.6%). Outcomes were assessed in 897 patients (484 ESA treated and 413 untreated). ESA treatment was associated with a nonsignificant survival benefit (HR 0.82, 95% CI: 0.65-1.04, P = 0.09); this benefit was larger amongst patients without prior transfusions (P = 0.07). Amongst 539 patients for whom response to ESA treatment could be defined, median time to first post-ESA treatment transfusion was 6.1 months (IQR: 4.3-15.9 months) in those transfused before ESA treatment compared to 23.3 months (IQR: 7.0-47.8 months) in patients without prior transfusions (HR 2.4, 95% CI: 1.7-3.3, P < 0.0001). Responding patients had a better prognosis in terms of a lower risk of death (HR 0.65, 95% CI: 0.45-0.893, P = 0.018), whereas there was no significant effect on the risk of progression to acute myeloid leukaemia (HR 0.71, 95% CI: 0.39-1.29, P = 0.27). CONCLUSION Appropriate use of ESAs can significantly delay the onset of a regular transfusion need in patients with lower-risk MDS.

Abstract
We report a case of mycotic pneumonia in a patient with acute myeloblastic leukemia. Rhizopus microsporus was identified as an agent of mucormycosis and proven by microscopy and culture. The determination of the isolate was supported by molecular methods. Combined treatment with surgery (right-sided pneumonectomy) and systemic amphotericin B and posaconazole antifungal therapy was chosen. In this case, amphotericin B Neo-Sensitabs tablets gave false "resistant" results on Mueller-Hinton agar when using the disk diffusion test. There was a good correlation between the Etest (16 h) and the Sensititre YeastOne microplate (24 h) for amphotericin B.

Abstract
OBJECTIVE Toxoplasmosis is a lifelong parasitic disease that appears to be associated to schizophrenia. However, no distinguishing attributes in Toxoplasma-infected schizophrenia patients have been described as yet. METHOD We searched for differences in symptom profile, cognitive performance and treatment response between 194 Toxoplasma-free and 57 (22.7%) Toxoplasma-infected schizophrenia patients treated in Prague Psychiatric Centre between 2000 and 2010. RESULTS Infected and non-infected patients differed in severity of symptoms (P = 0.032) measured with the Positive and Negative Symptom Scale (PANSS). Infected patients scored higher in positive subscale of PANSS, but not in the general and negative subscales. Infected men scored higher also in Total PANSS score, and negative, reality distortion, disorganisation and cognitive scores. Higher PANSS scores of positive, negative and disorganised psychopathology were associated with the lower titres of anti-Toxoplasma antibodies suggesting that psychopathology deteriorates with duration of parasitic infection. Infected patients remained about 33 days longer in hospital during their last admission than uninfected ones (P = 0.003). Schizophrenia started approximately 1 year earlier in infected men and about 3 years later in infected women, no such difference was observed in uninfected subjects. CONCLUSION Latent toxoplasmosis in schizophrenia may lead to more severe positive psychopathology and perhaps less favourable course of schizophrenia.
