Polypharmacy, immobilization, heart failure and depression were documented as predictors of use of potentially inappropriate medication. In depressive patients, drugs other than antidepressants contributed to the extensive use of potentially inappropriate medication. The observed prevalence of use of potentially inappropriate medication in older hospitalized Slovak patients was lower than the prevalence previously documented in Poland and the Czech Republic, but higher than in Croatia and Turkey. The identified risk factors were consistent with previous findings from other parts of Europe.
Our study confirmed a relatively high prevalence of polypharmacy in Slovak elderly patients. Polypharmacy risk rose especially with the increased prevalence of diseases of advancing age (diabetes mellitus, heart failure, arterial hypertension, dementia and cerebrovascular diseases). The increasing numbers of medications in inpatients indicate the need for the careful re-evaluation of pharmacotherapy during the stay in hospital.
Participants in a study of occupational exposure to mineral fibres in Slovakia were analysed for the polymorphism 23A-->G in the DNA repair gene XPA. Of the 388 subjects, 239 were exposed to asbestos, stonewool or glass fibre; the rest were unexposed controls. Levels of DNA base alterations (oxidation and alkylation) in lymphocytes were measured using the comet assay with lesion-specific endonucleases. 8-oxoguanine DNA glycosylase (OGG1) DNA repair activity was measured, as incision activity of a lymphocyte extract on DNA containing the OGG1 substrate 8-oxoguanine. Presence of the A allele was associated with higher levels of DNA damage (sites sensitive to formamidopyrimidine DNA glycosylase, endonuclease III or 3-methyladenine DNA glycosylase II) as well as with higher activity of OGG1 repair enzyme. DNA base damage increased with age, showing highly significant correlations when the whole population or subgroups of the population were analysed. OGG1 repair activity also increased with age, but when analysed according to XPA genotype, the increase was observed only in those individuals with an A allele. Although XPA is known as a protein involved in nucleotide excision repair of UV-induced damage and bulky DNA adducts, it may also have a role in the repair of oxidized bases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
