Statistical data on officially registered cases of health care-associated infections (HCAIs) in Ukraine in the period 2009-2019 have been analysed. On average, 5089±756 cases of HCAIs were registered annually. Odessa region of Ukraine is the leading country in the number of reported cases. The majority of HCAIs cases involve surgical and therapeutic invasive interventions and perinatal HCAIs. On average, 78.0±5.8 % of HCAIs cases involved adults. The estimated minimum number of HCAIs in Ukraine was expected to be about 1 million per year. Official statistics on registered cases of HCAIs in Ukraine do not reflect reality, so the system of registration and investigation of HCAIs in Ukraine needs to be reformed.
The analysis presented in this article is a continuation of a broader qualitative study examining the composition of the chloroform fraction of Caltha palustris. The study discovered 29 compounds, and 26 of them have been identified:paraffinic hydrocarbons, esters, fatty aldehydes, morphine derivatives, thiazole derivatives, benzodiazepines, naphthalene, and a small amount of terpene. It was figured out that the investigated lipophilic extract has an antioxidant impact. For the investigation, there were used such assays as the DPPH radical and the ABTS radical cation assays. Moreover the investigated lipophilic extract has an antimicrobial activity both in terms of gram-positive (Staphylococcus aureus (ATCC 25923 (F-49)), Bacillus cereus 34 (non-MDR), Enterococcus faecalis 26(MDR) and gram-negative, (Raoultella terrigena (ATCC 33257), Escherichia coli (ATCC 25922), Escherichia coli 168) microorganisms and yeast Candida spp. In addition, the significant content of biologically active substances in the lipophilic volatile fraction of Caltha palustris indicates the prospects for further study. © 2023, Research Journal of Pharmacy and Technology.

Synthesis and study of new polyfunctionalized 2-hydrazinoanthraquinone derivatives as potential antimicrobial agents. Methods. Organic synthesis, NMR and LC-MS spectroscopy, agar diffusion and broth microdilution methods. Results. A series of anthraquinonehydrazone derivatives are synthesized using the reaction of 2-(morpholinodiazenyl)anthracene-9,10-dione with methylene active compounds in the acetic acid medium. The screening of antimicrobial activity identified the compounds with significant effects against the tested microorganisms with MIC value <186.9 μM. Compounds 5 and 11 with MIC <93.5 μM are effective against yeast fungi whereas compound 5 with MIC <186.9 μM is effective against P.putida, which is multidrug resistant to antibiotics.
