Correlates of Premenstrual Syndrome in Polish Adolescents-Results from POLKA 18 Youth-Led Cross-Sectional Study.

This study aims to evaluate the prevalence of premenstrual syndrome (PMS) among Polish adolescents and explore its associations with mental health outcomes, lifestyle factors, and risk behaviours. Additionally, it seeks to examine the impact of PMS on quality of life, contributing to the foundation for initiatives that enhance adolescent menstrual health. This research is part of the POLKA 18 study, a youth-led cross-sectional survey conducted between April and December 2019.

Dysmenorrhea in Polish Adolescent Girls: Impact on Physical, Mental, and Social Well-Being-Results from POLKA 18 Study.

: Dysmenorrhea, characterised by painful menstrual cramps, is a pressing issue among adolescent girls globally. It significantly impacts their quality of life and has been associated with increased mental health issues and engagement in risky behaviours like smoking. In Poland, there is limited research on menstrual health, emphasising the need for a study to understand dysmenorrhea experiences and their impact on young menstruating individuals.

Measuring the Diameter of Single-Wall Carbon Nanotubes Using AFM.

In this work, we identify two issues that can significantly affect the accuracy of AFM measurements of the diameter of single-wall carbon nanotubes (SWCNTs) and propose a protocol that reduces errors associated with these issues. Measurements of the nanotube height under different applied forces demonstrate that even moderate forces significantly compress several different types of SWCNTs, leading to errors in measured diameters that must be minimized and/or corrected. Substrate and nanotube roughness also make major contributions to the uncertainty associated with the extraction of diameters from measured images.

HPV Vaccination among Polish Adolescents-Results from POLKA 18 Study.

Human Papillomavirus (HPV) is the main cause of cervical cancer and genital warts and constitutes one of the most common sexually transmitted infections. Cervical cancer is the only reproductive cancer that has a primary prevention programme through the introduction of HPV vaccinations. Even though the majority of European countries have nationally funded HPV vaccination programmes, in Poland these are exclusively local and scarcely funded.

Surface chemistry of metal oxide nanoparticles: NMR and TGA quantification.

Surface functionalization is widely used to control the behavior of nanomaterials for a range of applications. However, methods to accurately quantify surface functional groups and coatings are not yet routinely applied to nanomaterial characterization. We have employed a combination of quantitative NMR (qNMR) and thermogravimetric analysis (TGA) to address this problem for commercial cerium, nickel, and iron oxide nanoparticles (NPs) that have been modified to add functional coatings with (3-aminopropyl)triethoxysilane (APTES), stearic acid, and polyvinylpyrrolidone (PVP).
