Background: E-cigarettes are electronic nicotine-dispensing systems in the form of an aerosol. Their popularity among adolescents is growing at an exceedingly fast pace. Methods: This study aimed to determine the prevalence of the use of traditional cigarettes and e-cigarettes and identify demographic risk factors for the use of these products by adolescents in large and small cities and rural areas in Poland. This cross-sectional study conducted in 2021 aimed to assess the prevalence of traditional cigarette and e-cigarette use among adolescents aged 12–18 in Poland, while identifying demographic risk factors associated with their usage. A total of 10,388 adolescents participated, predominantly from rural areas. Results: Findings revealed that 12.3% were traditional cigarette smokers, with 90% smoking in the past month, while 14.9% were e-cigarette users, with 84.7% using them in the past month. Dual users accounted for 6.4% of respondents. Non-smokers were younger, and e-cigarette users were more likely to be boys from larger cities. Moreover, mothers of non-smokers tended to have higher education levels than those of traditional cigarette smokers. Conclusions: This study provides important new insights into demographic predictors associated with the use of specific devices, which can help inform targeted interventions to reduce e-cigarette use.

Contact of aquatic microbiocenoses with antibiotics present in the environment can cause the former to develop resistance to antimicrobial drugs. Therefore, the search for methods to detect antibiotics and drug-resistant microorganisms in the environment is important. The presented paper proposes a simple procedure to assess environmental exposure to antibiotics and the presence of non-susceptible microorganisms. Medium solutions with selected antibiotics and a microbial growth indicator were applied to test plates, and were inoculated with water samples from various ecosystems. After incubation, the susceptibility of the microorganisms to antibiotics was determined and presented in chronic microbial toxic concentration (MTC) values. It was confirmed that the presented procedure enables the assessment of the antibiotic susceptibility and adaptation potential of unselected microorganisms from different aquatic ecosystems. However, the MTC values depend on the inoculum volume, the density and seasonal activity of the microorganisms, the method of inoculum preparation, and the incubation time of the test plate. The described procedure may be practically applied as a screening test to identify the presence of drug-resistant microorganisms. Additionally, it may also be suitable as a method to assess environmental exposure to antibiotics. However, prior standardisation is required before implementing this procedure in quantitative studies.

In recent years, the prevalence of tobacco and electronic cigarette (e-cigarette) use among adolescents has raised significant public health concerns worldwide. This study aimed to investigate respiratory symptoms among Polish adolescents. We conducted an online survey among Polish school students from all provinces, collecting data over two months in spring 2021. Students voluntarily complete the anonymous survey, answering questions about respiratory symptoms, smoking habits (both traditional and electronic cigarettes), and demographic information. The analysis focused on four subgroups, namely non-tobacco users, traditional cigarette smokers, e-cigarette users, and dual users, totaling 10,388 pupils aged 12–18 years, predominantly attending secondary technical and comprehensive schools. A total of 10,388 pupils participated in the study, 55.6% (5778) of whom were girls and 44.4% (4610) boys. Adolescents who admitted using both e-cigarettes and traditional cigarettes experienced more frequent episodes of cough during the day (39.70%) and at night (18.40%) compared to their peers in other groups. Chest discomfort, including pain and pressure, was also reported more often by adolescents who used e-cigarettes and traditional cigarettes concurrently (27.60%) compared to their peers in other groups. Chest pressure was experienced less commonly by non-smoking adolescents (14.40%) than by smokers (18.90%). Higher severity of cough during the day and at night was observed in the group of adolescents using traditional cigarettes and e-cigarettes concurrently compared to the other groups. The adolescents in the dual-user group experienced more severe dyspnea and wheezing compared to the other groups included in the comparison. The results of this study confirm the correlation between the occurrence of respiratory symptoms in adolescents who smoke cigarettes, adolescents who use e-cigarettes, and adolescents who are dual users. The respiratory symptoms occur most frequently and are the most severe in the group of adolescents who use e-cigarettes and traditional cigarettes

E-cigarettes were initially developed to aid smoking cessation, evolving from basic cigarette-like devices to more advanced versions. However, despite bans and restrictions, they remain easily accessible to young individuals and contribute to addiction. Studies show that early initiation of vaping in adolescents significantly increases the risk of eventually smoking conventional cigarettes, posing a serious public health problem. This review focused on analysing the harmful effects of electronic cigarettes on the respiratory system in adolescents through original articles and case reports. A total of 24 studies that focused on the effects of e-cigarettes on the respiratory system in adolescents were selected. The studies assessed the occurrence of respiratory system disorders, the impact on asthmatic adolescents, and the relationship between e-cigarette use and the SARS-CoV-2 pandemic. Several studies have demonstrated that adolescents who use e-cigarettes are at an increased risk of experiencing respiratory symptoms. The pandemic has brought about changes in e-cigarette use among teenagers, including reduced use due to health concerns and limited access, as well as increased nicotine levels in response to stress and boredom. It is crucial for healthcare professionals to screen adolescents for e-cigarette use, educate them about the potential harm, and consider e-cigarettes as a possible cause of respiratory symptoms.

The study aimed to analyze the dynamics of changes in expenditures on opioid drugs, the structure of these expenditures, and the level of patients' share in the costs of treatment through payments from their pocket. This retrospective study includes data about the sale of prescription pain medications reimbursed in Poland in general pharmacies in 2017-2022. The drugs included in this analysis were simple analgesic opioids containing the following active substances: dihydrocodeine, fentanyl, tapentadol, methadone, morphine, and oxycodone, available through the Polish reimbursement program in pharmacies. Based on secondary data available from the payer of healthcare services in Poland, an Excel database was created to analyze. The share of reimbursement of the analyzed opioid drugs from public funds of the National Health Fund (NFZ) systematically increased from 83.1% in 2019 to 91.2% in 2022. In 2022, the structure of expenditure on opioid drugs was as follows: fentanyl (82.69%), oxycodone (7.83%), morphine (6.30%), tapentadol (1.7%), methadone (0.91%), and dihydrocodeine (0.57%). The lowest dynamics of change in expenditure year to year was observed in the case of fentanyl (+12.8% in 2018 vs. 2017, and -14% in 2021 vs. 2020). The largest year-on-year change in spending was observed for methadone (-20.2% in 2018 vs. 2017, and +131% in 2021 vs. 2020). We observed that patients' participation in co-payments for the analyzed analgesics was small. Monitoring the sale of opioids in public pharmacies is an important way to observe the situation of opioid use among Polish patients.

Despite nearly nine thousand publications on e-cigarettes (EC) in the PubMed database, there is still no consensus in the scientific community and among decision makers regarding the risks and benefits of using these products

Electronic cigarettes are available in a variety of devices with e-liquids also available in many flavors, and nicotine concentrations, albeit less than 20 mg/mL in Europe. Given the dynamics of these products, it is important to evaluate product content, including labeling, nicotine content versus labeled claim, nicotine form, and other aspects that may help policy decisions and align with the Tobacco Product Directive (TPD). Herein, we performed a study on 86 e-liquids from seven European countries (Croatia, Czech Republic, France, Germany, Italy, Poland, and the United Kingdom) with 34 different liquid brands and 57 different flavors. Nicotine content versus labeled claim, labeling, volume, pH, and nicotine form (i.e., freebase nicotine) were evaluated. From all tested products, eight of them from Germany, Poland, and UK (from 3 to 18 mg/mL), met the ±2% criteria. The ±10% criteria was fulfilled by 50 (58.1%) liquids from all countries. Among 71 liquids which contained nicotine, (one e-liquid labeled as 6 mg/mL had no nicotine level quantified), the amount of freebase nicotine differed from 0 to 97.8%, with a mean value 56.5 ± 35.7. None of the tested liquids had nicotine salt listed in the ingredients. Therefore, a low level of freebase nicotine in some liquids was most likely achieved by added flavorings. All tested liquids presented in this study met the basic requirements of the TPD. There were differences in the scope of information about harmfulness, type of warnings on packaging, attaching leaflets, placing graphic symbols, and discrepancies between the declared and quantified nicotine concentrations.

According to the World Health Organization, cardiovascular diseases are responsible for 31% of global deaths. A reduction in mortality can be achieved by promoting a healthy lifestyle, developing prevention strategies, and developing new therapies. Polyphenols are present in food and drinks such as tea, cocoa, fruits, berries, and vegetables. These compounds have strong antioxidative properties, which might have a cardioprotective effect. The aim of this paper is to examine the potential of polyphenols in cardioprotective use based on in vitro human and rat cardiomyocytes as well as fibroblast research. Based on the papers discussed in this review, polyphenols have the potential for cardioprotective use due to their multilevel points of action which include, among others, anti-inflammatory, antioxidant, antithrombotic, and vasodilatory. Polyphenols may have potential use in new and effective preventions or therapies for cardiovascular diseases, yet more clinical studies are needed.

Polyphenols have recently gained popularity among the general public as products and diets classified as healthy and containing naturally occurring phenols. Many polyphenolic extracts are available on the market as dietary supplements, functional foods, or cosmetics, taking advantage of clients’ desire to live a healthier and longer life. However, due to the difficulty of discovering the in vivo functions of polyphenols, most of the research focuses on in vitro studies. In this review, we focused on the cardioprotective activity of different polyphenols as possible candidates for use in cardiovascular disease therapy and for improving the quality of life of patients. Thus, the studies, which were mainly based on endothelial cells, aortic cells, and some in vivo studies, were analyzed. Based on the reviewed articles, polyphenols have a few points of action, including inhibition of acetylcholinesterase, decrease in reactive oxygen species production and endothelial tube formation, stimulation of acetylcholine-induced endothelium-derived mediator release, and others, which lead to their cardio- and/or vasoprotective effects on endothelial cells. The obtained results suggest positive effects of polyphenols, but more long-term in vivo studies demonstrating effects on mechanism of action, sensitivity, and specificity or efficacy are needed before legal health claims can be made.
