Facilitators and Barriers to Utilization of Psychosocial Care in Adolescents and Young Adults with Advanced Cancer: Integrating Mobile Health Perspectives.

Purpose: Although targeted psychosocial programming for adolescents and young adults (AYAs) with advanced cancer is a well-described priority, how best to engage AYAs in that programming is less clear. We aimed to examine AYA perspectives on facilitators and barriers to utilization of psychosocial programs and preferred mode of delivery. Methods: In this nested cohort study, AYAs participated in semistructured 1:1 interviews on communication needs. The present analysis focused on questions regarding psychosocial program delivery. Data were analyzed using directed content analysis followed by thematic content analysis to further organize and refine identified global themes and organizational themes. Results: We interviewed 32 patients (Mage = 18, range 14-25, 41% female). Key facilitators to utilization of psychosocial services by AYAs were to (1) align in importance of coping skills, (2) emphasize AYA self-motivation and agency in approach and introduction to services, and (3) offer services to everyone and at multiple timepoints. Key AYA barriers included (1) considering themselves an exception to the rule when discussing the psychosocial needs of AYAs with cancer, (2) the challenge of starting something new, and (3) reluctance to share emotional problems with psychosocial clinicians. Regarding the mode of delivery, some preferred in-person delivery due to opportunities for developing a close relationship and therapeutic rapport-building. Mobile app-based delivery was universally appealing. Conclusion: We provide a potential framework to increase uptake of psychosocial services in the high needs population of AYAs with advanced cancer. Future research will explore implementation strategies for increasing AYA engagement in psychosocial intervention programs.

Mesenteric arterial dysfunction in the UC Davis Type 2 Diabetes Mellitus rat model is dependent on pre-diabetic versus diabetic status and is sexually dimorphic.

Previous reports suggest that diabetes may differentially affect the vascular beds of females and males. However, there is insufficient evidence to establish the timeline of the vascular dysfunction in diabetes, specifically in relation to sex. Here, we determined whether mesenteric arterial function is altered in UC Davis Type-2 Diabetes Mellitus (UCD-T2DM) rats and if this occurs as early as the pre-diabetic stage of the disease. Specifically, we investigated whether vascular dysfunction differs between pre-diabetic or diabetic status and if this varies by sex. We measured the responses to endothelium-dependent and -independent vasorelaxant as well as vasoconstrictor agents and explored the potential mechanisms involved in sex-specific development of arterial dysfunction in UCD-T2DM rats. In addition, indices of insulin sensitivity were assessed. We report the reduced insulin sensitivity in pre-diabetic males and diabetic females. Vascular relaxation to acetylcholine was impaired to a greater extent in mesenteric artery from males in the pre-diabetic stage than in their female counterparts. In contrast, the arteries from females with diabetes exhibited a greater impairment to acetylcholine compared with diabetic males. Additionally, the sensitivity of mesenteric artery to contractile agents in females, but not in males, after the onset of diabetes was increased. Our data suggest that the reduced insulin sensitivity through AKT may predispose vessels to injury in the pre-diabetic stage in males. On the other hand, reduced insulin sensitivity as well as enhanced responsiveness to contractile agents may predispose arteries to injury in the diabetic stage in females.
