Adolescents with type 1 diabetes (T1D) are at risk of disengaging from regular care, particularly during the transition to adult care. In emerging adults with T1D, our objectives were to 1) describe health-care utilization after transfer to adult care, and 2) determine predictors of gaps in diabetes care visits after transfer from pediatric to adult care.

Gestational diabetes (GDM) and gestational hypertension (GHTN) are established cardiovascular disease (CVD) risk indicators, but the nuances of patterns across pregnancies are uncertain. The current evidence forces ‘ever GDM/never GDM’ and ‘ever GH/never GH’ dichotomies when incorporating these into CVD risk assessment; however, it is unclear whether CVD risk increases with GDM/GHTN recurrence, with first time occurrence in a second pregnancy, or with first pregnancy occurrence followed by second pregnancy absence. We are examining GDM/GHTN history across two singleton pregnancies in relationship to the development of CVD.

Gestational diabetes mellitus (GDM) is one of the most common complications of pregnancy and can lead to adverse outcomes for both mother and offspring. Studies indicate that sufficient maternal glycemic management decreases the risk of adverse outcomes. However, the optimal GDM diagnostic test or cut-points remains controversial. The Diabetes Canada 2018 guidelines suggest 2 approaches to screen for GDM; both include a fasting 75-gram oral glucose tolerance test (OGTT), but with different diagnostic cut-points. Our study focused on women with OGTT results between these 2 sets of thresholds, which we refer to as "grey zone" results.

Virtual peer communities in diabetes may be effective sources of social support, but their evaluation is largely limited to enumeration and thematic analyses of posts, comments, and reactions. In this evaluation, we aimed to quantify social network metrics such as the "centrality" of individual members; "views" as a measure of passive participation alongside more active communication; and types and subtypes of social support. We examined the Virtual Peer Network private Facebook page for young persons 14 to 24 years old with type 1 diabetes (VPN-T1D) in Canada, which we built in partnership with peer leaders.

Over 25% of children with type 1 diabetes (T1DM) in Quebec are diagnosed at the time of emergency presentation with diabetic ketoacidosis (DKA) (CJD, 2022). Knowledge of T1DM indicators may promote earlier detection. Our group identified a link between gestational diabetes (GDM) and pediatric diabetes (CMAJ, 2019). Whether this association comes from household/genetic factors or the intrauterine environment, is unknown. To gain insight into this issue, we are examining the associations of GDM during a sibling's pregnancy with T1DM in the subject.

To assess adult diabetes care providers’ current transition practices, knowledge about transition care, and perceived barriers to implementation of best practices in transition care for emerging adults with Type 1 diabetes mellitus.

Aims We examined the association between socio-demographic marginalization and plasma glucose levels at diagnosis of gestational diabetes in a multi-ethnic and socio-economically diverse patient group.Methods Medical charts at a Toronto gestational diabetes clinic were reviewed for women with a recorded pregnancy between 1 March 2006 and 26 April 2011. One-hour 50-g glucose challenge test values and postal code data were abstracted. Postal codes were merged with 2006 Canadian census data to compute neighbourhood-level ethnic concentration (% recent immigrants, % visible minorities) and material deprivation (% low education, % low income, single-parent households). We compared women in the highest neighbourhood quintiles for both ethnic concentration and material deprivation with all other women to explore an association between marginalization and diagnostic glucose levels. Multivariate regression models of glucose challenge test values and insulin prescription were adjusted for age, prior gestational diabetes, parity and diabetes family history.Results Among 531 patients with complete glucose challenge test data (mean 11.94 mmol/l, SD 1.83), those in the most marginalized neighbourhoods had 0.43 mmol/l higher glucose challenge test values (95% CI 0.08-0.78) compared with the rest of the study population. Other factors associated with higher glucose challenge test values were prior gestational diabetes (0.59 mmol/l increment, 95% CI 0.19-0.99) and diabetes family history (0.32 mmol/l increment, 95% CI -0.01 to 0.66). Each additional 1 mmol/l glucose challenge test result was associated with an increased likelihood of being prescribed insulin (odds ratio 1.33, 95% CI 1.17-1.51).Conclusions Women living in the most materially deprived and ethnically concentrated neighbourhoods have higher glucose levels at diagnosis of gestational diabetes. They may need close monitoring for timely initiation of insulin.
