Aims: To design a regional clinical service for people with early-onset type 2 diabetes (EOT2D) in Leicester, Leicestershire and Rutland (England).

Methods: A literature search was undertaken to identify important considerations. A working group of key stakeholders was formed to design a triage system and service pathway. Electronic medical records (EMRs) were searched (15th November 2023) to assess feasibility of the pathway and adapt accordingly.

Results: A literature search identified important considerations: High risk of complications; large proportion from minority ethnic and socioeconomically deprived backgrounds; significant psychological burden; stigma and other social challenges; and misclassification and miscoding. Novel clinical risk criteria were developed, implementable in EMRs, to match intervention-intensity to clinical need. Specialist clinics were planned, one for people at the highest-clinical risk, another for women with adverse perinatal risk factors. A healthcare professional training package was developed to increase awareness of the unmet clinical needs of people with EOT2D and to upskill in provision of holistic care. Subsequent EMR searches supported the need for our service. Due to the large numbers with HbA1c ≥86mmol/mol (10.0%; n=299; 10.8% of total), these people were prioritised for clinic access. We opted for specialist nurse/educator support to practices with clustering of patients and to financially incentivise referrals from primary care into services.

Conclusions: We showcase a service specifically for people with EOT2D based on the literature, a broad range of stakeholder involvement and utilising a locally-sourced data-driven approach. We further discuss areas for development and recommendations based on the challenges we encountered.

Aims: This systematic review aimed to summarize knowledge on explanatory variables of PA, SB and sleep in adults with T1D to support the development of healthy lifestyle interventions.

Methods: A systematic search of four databases (PubMed, Web of Science, Scopus and Embase) was performed. Only objective measurements of PA, SB and sleep were included and all explanatory variables were classified according to the socio-ecological model (i.e. intrapersonal, interpersonal, environmental and policy level). Risk of bias (ROB) (Joanna Briggs Institute appraisal checklists) and level of evidence (Evidence-Based Guideline Development) were assessed.

Results: Twenty-one studies were included (66.7% low ROB). Most explanatory variables were situated at the intrapersonal level. A favourable body composition was associated with more time spent in total PA and moderate-to-vigorous PA (MVPA). Men with T1D spent more time in MVPA than women and a younger age was associated with increased MVPA. Barriers to PA were indeterminately associated with MVPA and HbA1c showed an indeterminate association with sleep. Explanatory variables of SB and light PA were not studied in at least two independent studies.

Conclusion: This review underscores the focus on the individual level to identify explanatory variables of movement behaviours in adults with T1D, despite the necessity for a socio-ecological approach to develop effective interventions. More evidence on psychological, interpersonal and environmental variables is needed as these are modifiable.

Aims: To determine the prognosis associated with severe hypoglycaemia (SH) and diabetic ketoacidosis (DKA) in adults presenting to a hospital emergency department (ED).

Methods: Medical records of adults with type 1 (T1D) and type 2 (T2D) diabetes who attended the ED with SH and DKA between 1 January 2019 and 30 June 2023, were reviewed for comorbidities, long-term survival, mortality and causes of death.

Results: A total of 429 episodes of DKA occurred in 293 people and 643 episodes of SH in 515 people. DKA predominated in T1D (77.6%) and SH in T2D (54.3%). In T2D, 32.3% of DKA events were associated with sodium-glucose cotransporter-2 inhibitor (SGLT2-i) medication. In both SH and DKA, patients with T2D were older and had more comorbidities than T1D, particularly cardiorenal disease, heart failure, cognitive impairment and cancer (all p < 0.005). Compared with T1D, mortality was higher in T2D after SH (48.4% vs. 19.9%, p < 0.005) and after DKA (30.8% vs. 13.4%, p = 0.001) with shorter median times to fatal outcome (SH: 134 vs. 511 days; DKA: 43 vs. 266 days, both p < 0.005). Long-term survival was lower (p < 0.005) and mortality risk was higher in T2D after index presentation with SH (HR 3.43 [95% CI: 2.43-4.84], p < 0.005) and DKA (HR 3.00 [95% CI: 1.77-5.10], p < 0.005). Irrespective of diabetes type, most causes of death in SH and DKA were non-cardiovascular.

Conclusions: SH and DKA events requiring hospital treatment herald a poor prognosis with greater mortality in T2D adults with multimorbidity. A significant number of DKA episodes in T2D occurred in people receiving SGLT2-i medication.

Aims: Islet antibody-negative type 1 diabetes mellitus (T1DM) has not been well characterised. We determined the frequency of antibody-negative T1DM and compared it with antibody-positive T1DM in a cohort of north Indian children.

Methods: In a multi-centre, prospective, observational study, 176 Indian children (age 1-18 years) were assessed within 2 weeks of diagnosis of T1DM. Antibodies against GAD65 (GADA), islet antigen-2 (IA-2A) and zinc transporter 8 (ZnT8A), were estimated using validated ELISA. HLA-DRB1, DQA1 and DQB1 alleles were studied by Luminex-based typing. Monogenic diabetes was determined by targeted next-generation sequencing using the Illumina platform.

Results: After excluding 12 children with monogenic diabetes, GADA, IA-2A and ZnT8A were present in 124 (76%), 60 (37%) and 62 (38%) o children, respectively, while 24 (15%) were negative for all antibodies. A single antibody (most frequently GADA) was present in 68 (41%) of children, while all three antibodies were found in 34 (21%). Islet antibody-negative T1DM (n = 24, 15%) did not differ from antibody-positive children in their clinical features, HbA1c or plasma C-peptide, both at onset or after 1 year follow-up (available in 62 children). The frequency of other organ-specific antibodies or high-risk HLA-DR and DQ alleles were also similar. Children with a single islet antibody did not differ from those with multiple antibodies.

Conclusions: The frequency of various islet-antibodies, in isolation and combination, differed considerably from studies among children of European descent with T1DM. Children with T1DM who were islet antibody-negative were indistinguishable from those who were antibody-positive.

Aims: The aim of this study is to determine the prevalence of impaired awareness of hypoglycaemia (IAH) and examine risk factors for IAH in adults with type 1 diabetes.

Methods: We conducted a population-based registry study of 10,202 adults (≥18 years) with type 1 diabetes using data from the Norwegian Diabetes Register for Adults. The registry used the 1-item Gold scale, measuring hypoglycaemia symptom awareness. We calculated the overall prevalence of IAH (Gold score ≥4) (95% CI) and prevalence for subgroups based on demographic and clinical variables. We estimated IAH prevalence based on continuous scales of age, diabetes duration and HbA_1c using predicted probabilities from generalised additive logistic regression models. Finally, we quantified the associations of selected variables on IAH prevalence using log-binomial regression models.

Results: Overall, 18.0% reported IAH (95% CI 17.2, 18.7). The prevalence increased linearly with the participants' age, whereas the associations of diabetes duration and HbA_1c with IAH were non-linear with higher prevalence in both lower and higher tails of their distributions. Multiple severe hypoglycaemic events, female sex, age ≥ 65 years, diabetes duration ≤4 years or ≥ 30 years, multiple DKA events and CGM use were associated with higher risk for IAH. HbA_1c 65-74 mmol/mol (8.1-8.9%) was associated with lower risk for IAH.

Conclusions: In this nationwide study, the IAH prevalence was 18.0%. Multiple hypoglycaemic events, female sex and diabetes duration were identified as important risk factors for IAH. Study findings highlight the complexity of self-reported hypoglycaemia symptom awareness and emphasise the importance of routinely addressing symptom awareness in diabetes follow-up.

Aims: To evaluate a mobile app that delivers mental health support to adults with type 1 diabetes (T1D) living in rural and remote communities using the Reach, Effectiveness, Adoption, Intervention fidelity, Maintenance (RE-AIM) framework.

Methods: This study recruited 46 adults to participate in a 6-month intervention using REACHOUT, a mobile app that delivers peer-led mental health support (one-on-one, group-based texting and face-to-face virtual). Baseline and 6-month assessments measured diabetes distress (DD), depressive symptoms and perceived support (from family/friends, health care team and peers) along with other RE-AIM metrics.

Results: Calculations for reach and adoption found that 3% of eligible adults enrolled in REACHOUT and 55% of diabetes education centres participated in recruitment efforts. Maintenance metrics revealed 56% and 24% of peer supporters and participants, respectively, became peer supporters for a subsequent randomized controlled trial of REACHOUT. Post-intervention reductions were observed for overall distress (p = 0.007), powerlessness (p = 0.009), management distress (p = 0.001), social perception distress (p = 0.023), eating distress (p = 0.032) and depressive symptoms (p = 0.009); and elevations in support from family/friends and peers. After adjusting for sex and age, only support-related improvements persisted. When analysing women and men groups separately, women reported lower levels of overall distress, three distress subscales, and higher levels of family/friends and peer support whereas men did not.

Conclusions: While reach was relatively low, metrics for adoption and maintenance are promising. Improvements in distress were observed for the total sample, but these changes were reduced when controlling for sex and age, with significance maintained only for women. Digital health-enabled peer support may be instrumental in the delivery of mental health support to geographically isolated communities.

Aims: Type 2 diabetes is linked to psychological distress and a doubled risk of depression. This study aims to characterize individuals with type 2 diabetes experiencing diabetes distress and/or depression in relation to lifestyle and metabolic outcomes.

Methods: A population-based survey in 2020 targeted individuals with type 2 diabetes (aged 18-75 years) in the Central Denmark Region. This cross-sectional study assessed diabetes distress (using Problem-Area-in-Diabetes-scale) and depression (via hospital diagnosis and prescribed medication) as exposures. Logistic regression, adjusting for potential confounders, compared exposed and non-exposed groups on lifestyle habits, metabolic factors and medication usage related to cardio-metabolic risks.

Results: Of 18,222 respondents with type 2 diabetes (46% response rate), 11% had depression, 14% had diabetes distress and 4% had both. Compared to those with neither condition, those with depression were more often smokers (OR: 2.0, 95% CI: 1.8; 2.3) and sedentary in leisure time (OR: 2.0, 95% CI: 1.8; 2.2). Diabetes distress was associated with elevated HbA1c (OR: 1.8, 95% CI: 1.5; 2.0) and treatment with insulin (OR: 1.8, 95% CI: 1.6; 2.0). Half with diabetes distress displayed stable blood glucose levels. Those with both conditions had a higher risk of sedentary behaviour (OR: 2.7, 95% CI: 2.3; 3.2), clinical insomnia (OR: 6.5, 95% CI: 5.5; 7.7) and low self-rated health (OR: 7.5, 95% CI: 6.3; 9.0) than those with either psychological condition in isolation.

Conclusions: This study emphasizes the importance of recognizing distinct features and risk factors associated with diabetes distress and depression in individuals with type 2 diabetes. Tailored care strategies for comorbid mental health issues are crucial for comprehensive management.
