Etiological factors of bloodstream infections in oncological patients, who was hospitalized at the National Institute of Maria Skłodowska-Curie - National Research Institute in Warsaw in 2020-2022.

Aim Of The Study: The purpose of the study was the microbiological analysis of bloodstream infections in patients hospitalized at the National Institute of Oncology, Maria Skłodowska-Curie - National Research Institute in the period from 01/01/2020 to 31/10/2022.

Material And Methods: In the period from 01/01/2020 to 31/10/2022, 18,420 blood cultures obtained from patients hospitalized at the NIO-PIB were analysed in the Department of Clinical Microbiology (total for the presence of bacteria and fungi). Culture for the presence of bacteria was carried out in the BactAlert automatic system by bioMerieux, and for fungi in the Bactec FX automatic system by Becton Dickinson.

Deepfakes and Democracy (Theory): How Synthetic Audio-Visual Media for Disinformation and Hate Speech Threaten Core Democratic Functions.

Observers fear that deepfakes will shake the very foundations of democracy. Notwithstanding, in-depth scholarly analyses of deepfakes' political impact are rare, and do not consider theories of democracy. This contribution helps close this research gap, drawing on Warren's problem-oriented democracy theory, as well as theories of deliberative democracy and contributions on the role of trust in democracies.

Small mutations in Duchenne/Becker muscular dystrophy in 164 unrelated Polish patients.

In the 164 patients with Duchenne/Becker muscular dystrophy, we found 142 different small mutations including 51 novel mutations not listed in the LOVD, the UMD-DMD, the ClinVar, and the HGMD databases. Among all mutations, nonsense mutations occurred in 45.7%, frameshift mutations in 32.

Perception of Old Age by the Inhabitants of Poland.

: People's self-esteem and public perception of senior citizens both play important roles in perceiving old age. The public perception manifests itself in adopting specific attitudes toward the elderly. : The work aimed at attempting to specify how adults and the elderly perceive old age.

Deletions, not duplications or small mutations, are the predominante new mutations in the dystrophin gene.

Examination of the carrier state was performed in 744 unrelated mothers of the Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) probands with identified mutations in the dystrophin gene. Owing to that it was possible to assess frequency and type of new mutations in the gene. Contrary to the Japanese observations of Lee et al.
