Background: Developmentally appropriate evidence-based sexual health education should be included as part of a comprehensive school health education program and be accessible to all students. The registered school nurse is a valuable resource to parents and educators in this area and supports the implementation of evidence-based sexual health education programs that promote healthy sexual development for adolescents. Methods: The research group consisted of 438 adolescents aged 12 to 15 years in a selected region in Slovakia, 186 boys and 252 girls. Average age of the girls was 13.2 and the boys 13.3 years. A nurse—a specialist in community nursing—collected the data using a self-designed questionnaire. The questions evaluated by the five-point Likert scale focused on finding out the knowledge and attitudes of adolescents to the role of school nurses regarding sexuality and reproductive health. Results were analyzed using parametric comparison tests with significance value 0.05: Student t-test for independent samples. Results: The girls and the boys most often drew information on sexuality and reproductive health from their parents and friends. The evaluation of the adolescents’ views on who should be a competent professional in the field of sexual education at schools found statistically significant differences between the boys and girls. For the boys and girls, a sexologist received the most significant assessment of competence. The interest in a school nurse in a school environment would be statistically significantly more appreciated by the girls compared to the boys, not just for solving problems related to healthy lifestyle, but also regarding sexuality, parenting and marriage. The adolescents consider the education for marriage and parenthood as the least discussed issue at present. In evaluating topics the adolescents would discuss, there were statistically significant differences between the boys and girls. Conclusions: A community or school nurse would also be able to successfully perform sexual education at schools. In Slovakia, this applied nursing discipline is lacking.

Microplastics are small plastic pieces with sizes less than 5 mm. They are becoming a global concern due to the potential risk to human health. The potential risks of microplastics may be greater for infants because they do not have sufficiently developed metabolizing enzymes, have less ability to remove microplastics, and have highly sensitive target organs. Infants should be breastfed for the first six months of life. Breast milk is considered to be the most complete and suitable source of nutrition. However, if breastfeeding during this period is not possible, it is necessary to use formulas designed for infant initial feeding. Infants may be exposed to higher levels of MPs through infant foods or plastic products. The aim of this study is to describe the possible sources of exposure to microplastics such as the human placenta, plastic feeding bottles, and toys as well as the presence of released microplastics in infant feces, breast milk, and infant formulas. There is still not enough data available for this study area. Therefore, it is necessary to pay increased attention to minimizing the negative effects of microplastics on human health.

4-Nonylphenol belongs to the alkylphenol group of chemicals, and its high occurrence in the environment can cause an adverse effect on human health. Breast milk can serve as a marker to take measure of human exposure to these chemicals through different routes of exposure. In this work, the influence of selected factors (the kind of water drank by the mothers; the consumption of fish, pork, and beef; wearing gloves; using nail polish, gel nails, vitamins, and medication) on the concentration on 4-nonylphenol in 89 breast milk samples was studied. The concentrations of nonylphenol in breast milk were determined by HPLC with fluorescence detection. The lowest and highest concentrations of 4-nonylphenol in breast milk were 0.97 ng/mL and 4.37 ng/mL, respectively. Statistical significance was observed for the consumption of pork (p = 0.048) and fish (0.041) in relation to the 4-nonylphenol concentration. Certain parameters (use of gel nails, beef consumption, and vitamin supplementation) were at the border of statistical significance (p = 0.06). Other parameters did not show any statistical significance. The results showed that breast milk in Slovakia does not contain a harmful dose of 4-nonylphenol and does not cause health problems. But it is necessary to continue this research and perform extended screening on a larger number of samples.

The extensive usage of mobile phones across all age brackets, including children and teenagers, leads to significant exposure to radiofrequency electromagnetic fields (RF-EMF). This exposure raises concerns about potential adverse effects on sleep. The current study aimed to explore the influence of mobile phone-emitted RF-EMFs on the duration and quality of sleep in a cohort of medical students. Participants alternated between sleeping with and without a mobile phone for two-week intervals, while their sleep patterns were monitored using smartwatches. The study results indicated no statistically significant disparities in sleep quality between sleeping with and without a mobile phone. However, exposure to radiofrequency electromagnetic fields had a notable impact on the minimum and average blood oxygen saturation levels.

Aim. Nurses can provide remote nursing care without the patient being physically present in a clinical setting, especially in the areas of tele-education, counselling, and telemonitoring. The goal was to create and implement the tele-education program of physical activity for mothers after a caesarean section and analyse its impact on their physical condition. Material and methods. The sample consisted of 411 participants with an average age of 31 years old. It was a quasi-experiment. To evaluate the effect of the tele-education program a self-constructed questionnaire was used. Data were processed using the Chi-square test and Cramer’s V. Results. Statistically signifi cant relationships were found between participation in the tele-education program and better physical condition of mothers after a caesarean section, specifi cally in terms of pain occurrence, wound healing, and gastrointestinal comfort. Conclusions. The fi ndings indicate the benefits of tele-education in gynaecological-obstetric nursing, suggesting that the development of telenursing is desirable and can contribute to increasing its accessibility, thereby aff ecting the quality of nursing care and satisfaction of mothers post-caesarean section.
