    Adolescents’ experiences of transition to self-management of type 1 diabetes: systematic review and future directions
    (Sage, 2023-11-05) Leocadio, Paula; Kelleher, Carol; Fernández, Eluska; Hawkes, Colin P.
    Purpose: The purpose of this systematic literature review was to explore studies that report the experiences of adolescents, their families, and health care professionals of adolescents’ transition to self-management of type 1 diabetes (T1DM). Methods: SocINDEX, PsycInfo, APA PsycArticles, and MEDLINE electronic databases were searched. Studies reporting on experiences of transition to self-management of T1DM for adolescents, their parents, siblings, and health care professionals published between January 2010 amd December 2021 were included. The Mixed Methods Appraisal Tool guided trustworthiness and relevance of selected studies. Results: A total of 29 studies met the inclusion criteria. Findings indicate that adolescents’ experiences of transitioning to self-management of T1DM are interconnected with the supports provided by others (eg, family, teachers, friends). Considering interdependence and collective lived experiences is essential to developing effective and personalized family, peer, and social interventions to facilitate transition and to avoid negative outcomes in later life. The renegotiation of roles within the network of supports that impact adolescents’ transition and adolescents’ self-negotiation have been neglected. Conclusion: Transition to self-management of T1DM is a dynamic and iterative process comprising of continuous shifts between interdependence and independence, making it challenging for all involved. A number of research gaps and avenues for future research are outlined.

    Stress during puberty exerts sex-specific effects on depressive-like behavior and monoamine neurotransmitters in adolescence and adulthood
    (Elsevier Inc., 2022-10-07) Harris, Erin P.; Villalobos-Manriquez, Francisca; Melo, Thieza G.; Clarke, Gerard; O'Leary, Olivia F.; Health Research Board; Science Foundation Ireland
    Psychiatric disorders including major depression are twice as prevalent in women compared to men. This sex difference in prevalence only emerges after the onset of puberty, suggesting that puberty may be a sensitive period during which sex-associated vulnerability to stress-related depression might become established. Thus, this study investigated whether stress occurring specifically during the pubertal window of adolescence may be responsible for this sex difference in depression vulnerability. Male and female rats were exposed to a three-day stress protocol during puberty (postnatal days 35–37 in females, 45–47 in males) and underwent behavioral tests in adolescence or adulthood measuring anhedonia, anxiety-like behavior, locomotor activity and antidepressant-like behavior. Brainstem and striatum tissue were collected from a separate cohort of behavioral test-naïve rats in adolescence or adulthood to quantify the effect of pubertal stress on monoamine neurotransmitters. Pubertal stress increased immobility behavior in the forced swim test in both sexes in adolescence and adulthood. In adolescence, pubertal stress altered escape-oriented behaviors in a sex-specific manner: decreasing climbing in males but not females and decreasing swimming in females but not males. Pubertal stress decreased adolescent brainstem noradrenaline specifically in females and had opposing effects in adolescent males and females on brainstem serotonin turnover. Pubertal stress induced anhedonia in the saccharin preference test in adult males but not females, an effect paralleled by a male-specific decrease in striatal dopamine turnover. Pubertal stress did not significantly impact anxiety-like behavior or locomotor activity in any sex at either age. Taken together, these data suggest that although pubertal stress did not preferentially increase female vulnerability to depressive-like behaviors compared to males, stress during puberty exerts sex-specific effects on depressive-like behavior and anhedonia, possibly through discrete neurotransmitter systems.
