This study aimed to determine the associations between parental monitoring and affection and three adolescent lifestyle aspects: constructive leisure, non-constructive leisure and substance use. A cross-sectional study was conducted in four countries (Chile, Mexico, Spain and Peru). Adolescents aged 12–15 self-completed a multi-purpose questionnaire. Multiple logistic regressions were performed to analyse the association between the parental monitoring and affection variables and the outcomes in terms of the children’s lifestyles. The results indicate that parental monitoring is conducive to more constructive leisure and less non-constructive leisure and seems to be conducive to the prevention of substance use. Furthermore, parental affection is conducive to constructive leisure and the prevention of substance use. The discussion focuses on the fact that the family can be a protective resource associated with positive adolescent development.

Cultural sensibility is an important concept linked to the achievement of cultural competence. Health professionals must first improve their cultural sensibility to become culturally competent and to be able to offer competent care to culturally diverse populations. Aim To develop and psychometrically test the Cultural Sensibility Scale for Nursing (CUSNUR), a cultural sensibility scale that can be used in nursing for the achievement of competencies needed to care for culturally diverse populations. The cross-sectional survey was conducted over two stages. The first stage involved the cross-cultural and discipline-specific adaptation of an existing scale addressing this concept in the field of law using the reverse translation method. Second, validation of the scale was carried out from October 2016-June 2017 by studying the psychometric properties of the questionnaire through an analysis of content acceptability and reliability and through exploratory factor analysis (EFA). The questionnaire was designed to be clear, easy to understand, and of adequate length, and experts involved in content validation agreed that the scale meets these criteria. A total of 253 nursing students participated in the validation stage. Four factors were identified from the EFA: (1) patient and health professional behaviours, (2) self-assessments, (3) self-awareness, and (4) cultural influence. Two items were excluded. Factorial saturation is adequate for all factors (>0.30). The Cronbach alpha was measured as 0.75. This study presents the first version of the CUSNUR and demonstrates that the scale is valid and reliable.

Objectives: This study aims to determine the association between parental competence (warmth, demandingness, and parental education in fortitude and in privacy) and pornography use. Methods: This study presents cross-sectional data from an ongoing international study (YOURLIFE Project) about the opinions and lifestyles of adolescents with respect to affectivity, love, and sexuality. Adolescents (N = 2516) aged 12–15 from Chile, Mexico, Peru, and Spain were included. Multiple logistic regressions were performed to analyze the association between family assets (parental demandingness, warmth, and parental fortitude and privacy education) and pornography use. Results: The results indicated an association between parental warmth and pornography use among boys and girls. Furthermore, privacy education was highly associated with less pornography use only in girls. Parental demandingness and parental fortitude education were not associated with pornography use. Conclusion: Our findings suggest that new educational perspectives including privacy issues should be considered within programs for pornography use prevention among adolescents. Parents should incorporate these variables when discussing pornography with their adolescents and not only focus on filters or demandingness.

Background/Objectives: The emergence of the Omicron variant has complicated COVID-19 control and prompted vaccine updates. Recent studies have shown that a fourth dose significantly protects against infection and severe disease, though long-term immunity data remain limited. This study aimed to assess Anti-S-RBD antibodies and interferon-γ levels in healthcare workers 12 months after receiving bivalent Original/Omicron BA.4-5 fourth SARS-CoV-2 vaccine. Methods: In this prospective cohort study, 549 healthcare workers were categorized by the initial vaccination schedule, with 229 individuals having received the fourth SARS-CoV-2 vaccine dose. Blood samples were collected from all participants 12 months post-vaccination. Results: Significant differences in Anti-S-RBD antibody levels were observed between those receiving a fourth dose and those who did not, while no differences were seen in interferon-γ levels. After 12 months, there were no significant differences in humoral and cellular immunity response between volunteers primoinfected or reinfected across different periods by the Omicron variant. A multivariable analysis revealed an association between high antibody levels (>6000 U/mL) and interferon-γ levels (OR: 3.13; 95% CI: 1.3–7.7; p < 0.05). Regarding primary vaccine schedules, participants vaccinated with ChAdOx1 (a single or double dose) had notably lower antibody levels compared to those who received mRNA-based vaccines. Additionally, the study shows a higher frequency of multiple infections among those with a single-dose ChAdOx1 primary schedule (OR: 6.24; 95% CI: 1.25–31.15; p < 0.01). Conclusions: Overall, mRNA-based vaccines exhibited stronger long-term immunogenicity. Repeated exposure to the Omicron variant seems to mitigate immune imprinting from the wild-type SARS-CoV-2. An association was observed between high antibody levels and a strong cellular response, although the correlation was not linear.
