Патогенез ренальных дисфункций при метаболическом синдроме

Анализируются патофизиологические механизмы возникновения и развития ренальных дисфункций в условиях метаболического синдрома (МС). Рассматриваются результаты популяционных клинических исследований деятельности почек у лиц с МС, а также механизмы, вызывающие нарушения гомеостатических функций почек в условиях течения МС. Проведен обзор литературы о роли ренин-ангиотензиновой системы и оксида азота в патогенезе ренальных дисфункций при МС.Analysis of pathophisiological mechanisms of renal dysfunctions development was carried out during metabolic syndrome. Results of clinic researches of renal activity in patients with metabolic syndrome (MS) and disturbances of homeostatic renal functions during MS were established. The literature review about research of renin-angiotensin system’s role and nitric oxide in pathogenesis of renal functions during MS was conducted

Pornography Use Profiles and the Emergence of Sexual Behaviors in Adolescence

This research longitudinally explored adolescent pornography (porn) consumption and its association with sexual development in early and middle adolescence. A four-wave design with half-year intervals investigated pornography consumption and different (sexual) activities, such as masturbation, French kissing, petting, giving/receiving manual and oral sex, and intercourse, among 630 respondents (47.9% female, mean age 13.7 years; SD = 0.48) years at T1). A latent growth mixture analysis of pornography consumption revealed two groups with relatively low pornography (LP; 51.8% of the boys, 91.4% of the girls) versus high pornography (HP; 48.2% of the boys; 8.6% of the girls) consumption across time. At T1, HP boys on average watched pornography less than once a month, but more than once a year at T1. At T4, their average pornography use had increased to almost one to two times a week. LP boys never watched pornography at T1. At T4, their average pornography use was still less than once a year. At T1, HP girls never watched pornography, but consumption increased to almost one to three times a month at T4. Across waves of the study, LP girls (almost) never watched pornography. A discrete-time survival mixture analysis of sexual developmental patterning indicated that, compared to their LP peers, both girls and boys in the HP groups showed accelerated development of masturbation, petting, and receiving manual sex. Girls in the HP group were also more inclined to receive oral sex, whereas boys in the HP group also showed earlier and more frequent manual sex and intercourse. Thus, whereas the HP group of boys was substantially larger compared to that of girls, pornography consumption was related to accelerated development of sexual activities for both genders across early and middle adolescence. The discussion deliberates on pornography as a driving force in adolescent sexual development versus pornography as a medium of choice for sexually advanced adolescents

HBSC 2021. Gezondheid en welzijn van jongeren in Nederland

De mentale gezondheid van meisjes in Nederland is tussen 2017 en 2021 sterk verslechterd. Dat blijkt uit het Health Behaviour in School-aged Children (HBSC)-rapport, met daarin de resultaten van 20 jaar onderzoek naar het welzijn en de gezondheid van jongeren in Nederland. Vandaag wordt het rapport tijdens het symposium ‘Jong in de 21ste eeuw’ in Utrecht uitgereikt aan Hare Majesteit Koningin Máxima

“Shake It Baby, Shake It”: Media Preferences, Sexual Attitudes and Gender Stereotypes Among Adolescents

In this study exposure to and preferences for three important youth media (TV, music styles/music TV, internet) were examined in relation to adolescents’ permissive sexual attitudes and gender stereotypes (i.e., views of men as sex-driven and tough, and of women as sex objects). Multivariate structural analysis of data from a school-based sample of 480 13 to 16-year-old Dutch students revealed that preferences, rather than exposure were associated with attitudes and stereotypes. For both girls and boys, preferences for hip-hop and hard-house music were associated positively with gender stereotypes and preference for classical music was negatively associated with gender stereotypes. Particularly for boys, using internet to find explicit sexual content emerged as a powerful indicator of all attitudes and stereotypes
