ABSTRACT
The study defines the basic terminological structure associated with the concepts of prescribing and medication use in relation to polypharmacy. Correctly naming the current prescription or use of a medication by a particular patient allows for the selection of an appropriate change to minimize the medication burden. The aim remains to maintain the desired therapeutic outcomes with an improved quality of life.

The contribution captures three basic concepts of the term polypharmacy. The analysis of four bibliographic databases demonstrates the importance of the correct and uniform use of terminology. It also approximates the most common numerical expression of the level of polypharmacy and the most common extended terms of polypharmacy.

The COVID-19 pandemic accelerated the online purchase of goods and services in which today's e-pharmacy is now an integral part of healthcare provisions in developed countries. The aim of our research was to assess the frequency and attitudes of European consumers purchasing medications online prior to and following the pandemic in the Visegrad Group countries (V4). An online cross-sectional study was conducted between May-August 2022. A 25-item questionnaire with single choice and 5-point Likert scale answers was used and implemented in Google forms and Pollfish. A sampling of 2087 responses was collected. A majority (92.8%) of the respondents were aware medicines can be purchased online, yet prefer traditional pharmacies (4.6 ± 0.8) and somewhat oppose the internet channel (2.8 ± 1.3). Following the outbreak of COVID-19 pandemic, respondents' attitude towards purchasing consumer goods (3.65 ± 0.89) and medications (3.26 ± 0.91) online increased, however, the change regarding medications is significantly smaller (p < 0.01). A distinct increase in the frequency of buying medicines (from 49.16% to 55.48%) and health products (from 60.61% to 63.0%) online was measured since the breakout of the COVID-19 pandemic (p < 0.05). Despite the relatively high prevalence witnessed in previous purchases, our results highlight the trend in which 18.3% of participants will definitely purchase medications online while a proportionate 17.7% will not in the future. Although long-term post-COVID attitudes towards the internet pharmacy channel have modestly increased, in comparison to previously published research the frequency of purchasing medications online has significantly increased during the past years. As national legislation in V4 countries permit only non-prescription online sales, our findings are primarily applicable to countries with similar regulatory environment. The rapid global spread of the coronavirus has transitionally affected medicinal purchase behaviors, augmenting potential public health concerns related to online sourcing. Consequently, public awareness campaigns are needed to promote verified online pharmacies and prevent the utilization of illicit websites and the use of unregistered, substandard and falsified medicinal products.
ABSTRACT
OBJECTIVES: We investigated the effects of the herbicide preparation Successor 600 on biochemical and haematological indices and the histolopathological parameters of common carp after 28 day exposure. Furthermore, the hepatosomatic index and induction of xenobiotic metabolizing enzymes and biomarkers were assessed. DESIGN: Juvenile fish were exposed to sublethal concentrations of Successor(R) 600 (0.06 mg L-1, 0.22 mg L-1 or 0.60 mg L-1) for 28 days. Haematological indices were assessed using unified methods of haematological examination in fish. Plasma biochemical indices were measured by biochemical analyzer, the vitellogenin concentration in male fish plasma was estimated by direct sandwich ELISA. In hepatopancreas, ethoxyresorufin-O-deethylase (EROD) activity was measured spectrofluorimetrically, concentration of total cytochrome P450 (CYP), glutathion (GSH) content and glutathion-S-transferase (GST) activity were determined spectrophotometrically. Histological changes in samples of hepatopancreas, skin, gills, spleen, head kidney and trunk kidney were examined by light microscopy. RESULTS: Haemoglobin, MCH and MCHC were significantly (p<0.05) reduced in fish treated with Successor(R) 600 of 0.22 and 0.60 mg L-1. LDH was enhanced (p<0.05), in the highest concentration of the preparation. Vitellogenin was detected in all male fish, with no difference between groups. HSI, GSH and GST were elevated (p<0.05), owing to the exposure, whereas CYP and EROD were not affected. Slight histopathological changes were demonstrated in skin, gills and hepatopancreas, with steroid tissue in head kidney samples of 0.60 mg L-1 treated fish. CONCLUSION: Successor 600 affected the haematological profile of the treated fish, while the effects on biochemical indices were less expressed. Male plasma vitellogenin concentrations were not indicative of estrogen disruptive effects after 28 days. The importance of GSH and GST for the metabolisation were demonstrated. In contrast, CYP and EROD were not influenced by any concentration tested. HSI was found to reflex pollution with Successor 600. Histopathological indices caused by the treatment were observed in various tissue samples of the treated fish.
