Parent-adolescent shared responsibility for diabetes care is advocated by experts to achieve beneficial diabetes and psychosocial outcomes for adolescents with type 1 diabetes. Parental autonomy support may be a way to facilitate this sharing. In this dyadic study, we examined parental diabetes-specific autonomy support experienced by adolescents with type 1 diabetes and their parents (n = 89 dyads), and its association with their experience of shared diabetes care responsibility.Path analysis was used to test an Actor-Partner Interdependence Model for parental autonomy support effects on shared responsibility. This was a secondary analysis of data from 89 parent-early/mid-adolescent dyads.Actor effects were identified. Parents' and adolescents' perceptions of parental autonomy support were associated with their respective reports of shared diabetes care responsibility. One partner effect was identified. Adolescents' reports of parental autonomy support were associated with parents' reports of shared responsibility. Parents and adolescents held similar views of autonomy support but discrepant views of shared responsibility. Older adolescents perceived less parental autonomy support.Increasing parental autonomy support may facilitate parent-adolescent sharing of diabetes care responsibility. Adolescent and parent perceptions influence each other and need to be considered when working with them to strengthen parental autonomy support.

Emerging adults with diabetes are assuming diabetes care responsibility, graduating from high school and leaving their parental homes. We examined: (1) how diabetes care responsibility changed in relation to time (high school to post high school) and living situation (living independently or not of parents) and (2) the association of diabetes self-efficacy, worry about hypoglycaemia, gender and glycaemic control with these changes in responsibility among emerging adults with type 1 diabetes. During the last 6 months in high school (T1), 113 participants completed diabetes care responsibility (total, daily and non-daily), diabetes self-efficacy and worry about hypoglycaemia scales. Participants again completed the responsibility scales post high school graduation (T2). We used a linear mixed-effects model with diabetes self-efficacy, worry about hypoglycaemia, time since graduation, living situation, gender and glycaemic control as independent variables; and diabetes care responsibility (total, daily and non-daily) as dependent variables. Moderation involving diabetes self-efficacy, worry about hypoglycaemia, gender and glycaemic control was also tested. Diabetes care responsibility increased over time for total (P0.001), daily (P= 0.002) and non-daily (P0.001), but the associations of self-efficacy and gender with diabetes care responsibility were moderated by living situation. Self-efficacy was negatively related to total (P= 0.006), daily (P= 0.010) and non-daily (P= 0.030) responsibility for those not living independently while positively related only to total responsibility (P= 0.028) for those living independently. Being female was positively related to total (P= 0.007) and non-daily (P= 0.001) responsibility for those living independently. Diabetes care responsibility increased from high school to post high school among these emerging adults with diabetes. There is a complex relationship between self-efficacy, gender and responsibility related to living independently of parents for these youth.

Several arguments suggest that dopamine (DA) plays a role in the physiopathology of migraine. Conjugated and unconjugated plasma and platelet DA, as well as platelet phenolsulfotransferase M activity (responsible for DA sulfatation) were measured in 30 control subjects, 27 common migraine patients between attacks and 9 migraineurs during an attack. No modification of any of the parameters tested was detected in attack-free periods. During the attack no change of conjugated DA was observed; in contrast, a significant decrease of unconjugated platelet DA and a significant and correlated increase of plasma unconjugated DA were demonstrated. This corresponds to a release of unconjugated DA by the very dense bodies in platelets of migraine patients during the attack.
