Background: Given limited data regarding the involvement of disadvantaged groups in paediatric diabetes clinical trials, this study aimed to evaluate the socioeconomic representativeness of participants recruited into a multinational clinical trial in relation to regional and national type 1 diabetes reference populations.

Methods: Retrospective, cross-sectional evaluation of a subset of adolescent type 1 diabetes cardiorenal intervention trial (AdDIT) participants from Australia (n = 144), Canada (n = 312) and the UK (n = 173). Validated national measures of deprivation were used: the Index of Relative Socioeconomic Disadvantage (IRSD) 2016 (Australia), the Material Resources (MR) dimension of the Canadian Marginalisation index 2016 (Canada) and the Index of Multiple Deprivation (IMD) 2015 (UK).

Article Synopsis
  • The study investigates whether adolescents with type 1 diabetes who have a high urinary albumin/creatinine ratio (ACR) are at an increased risk of diabetic retinopathy progression, regardless of their blood sugar control.
  • It involved 710 participants, split into high ACR and low ACR groups, and monitored their eye health over a median period of 3.2 years.
  • The findings revealed that those with high ACR, along with other factors like higher HbA levels and blood pressure, had a significantly higher risk of developing advanced diabetic retinopathy.

The prevalence of type 2 diabetes and obesity has risen dramatically for decades and is expected to rise further, secondary to the growing aging, sedentary population. The strain on global health care is projected to be colossal. This review explores the latest work and emerging ideas related to genetic and environmental factors influencing metabolism.

Article Synopsis
  • An increased albumin-creatinine ratio in normal ranges can indicate a higher risk of adverse cardio-renal outcomes in adolescents, suggesting the need for early intervention.
  • A study involving a randomized controlled trial and an observational cohort examined the effects of ACE inhibitors and statins on vascular health in 158 high-risk adolescents, revealing that ACE inhibitors led to improved endothelial function over a 2-4 year period.
  • While the trial showed no significant impact from statins on endothelial function, high-risk participants displayed symptoms of endothelial dysfunction compared to lower-risk individuals, highlighting ongoing concerns in cardiovascular health as they transition into adulthood.

Objectives: To identify biomarkers of renal disease in adolescents with type 1 diabetes (T1D) and to compare findings in adults with T1D.

Methods: Twenty-five serum biomarkers were measured, using a Luminex platform, in 553 adolescents (median [interquartile range] age: 13.9 [12.

Objective: Suboptimal adherence to insulin treatment is a main issue in adolescents with type 1 diabetes. However, to date, there are no available data on adherence to adjunct noninsulin medications in this population. Our aim was to assess adherence to ACE inhibitors and statins and explore potential determinants in adolescents with type 1 diabetes.

Objective: Baseline data from the Adolescent Type 1 Diabetes Cardio-Renal Intervention Trial (AdDIT) indicated that tertiles of urinary albumin-to-creatinine ratios (ACRs) in the normal range at age 10-16 years are associated with risk markers for diabetic nephropathy (DN) and cardiovascular disease (CVD). We aimed to determine whether the top ACR tertile remained associated with DN and CVD risk over the 2-4-year AdDIT study.

Research Design And Methods: One hundred fifty adolescents (mean age 14.

Article Synopsis
  • The study focused on preventing severe hypoglycemia in adults with type 1 diabetes through enhanced self-management techniques over 24 weeks.
  • Participants experienced improved awareness of hypoglycemia, with significant reductions in severe hypoglycemia episodes and improved HbA1c levels sustained for up to 24 months post-intervention.
  • The results suggest that structured education combined with effective insulin delivery and monitoring should be standardized for individuals with impaired hypoglycemia awareness.

Background: Among adolescents with type 1 diabetes, rapid increases in albumin excretion during puberty precede the development of microalbuminuria and macroalbuminuria, long-term risk factors for renal and cardiovascular disease. We hypothesized that adolescents with high levels of albumin excretion might benefit from angiotensin-converting-enzyme (ACE) inhibitors and statins, drugs that have not been fully evaluated in adolescents.

Methods: We screened 4407 adolescents with type 1 diabetes between the ages of 10 and 16 years of age and identified 1287 with values in the upper third of the albumin-to-creatinine ratios; 443 were randomly assigned in a placebo-controlled trial of an ACE inhibitor and a statin with the use of a 2-by-2 factorial design minimizing differences in baseline characteristics such as age, sex, and duration of diabetes.

Objective: To determine whether impaired awareness of hypoglycemia (IAH) can be improved and severe hypoglycemia (SH) prevented in type 1 diabetes, we compared an insulin pump (continuous subcutaneous insulin infusion [CSII]) with multiple daily injections (MDIs) and adjuvant real-time continuous glucose monitoring (RT) with conventional self-monitoring of blood glucose (SMBG).

Research Design And Methods: A 24-week 2 × 2 factorial randomized controlled trial in adults with type 1 diabetes and IAH was conducted. All received comparable education, support, and congruent therapeutic targets aimed at rigorous avoidance of biochemical hypoglycemia without relaxing overall control.

The nature of CKD in diabetes is changing. Diabetic glomerulosclerosis remains the cause of CKD in most type 1 diabetic individuals. However, the rate of progression of diabetic nephropathy has slowed because of improving glucose and blood pressure control.

Introduction: Despite optimal secondary prevention therapy following non-ST elevation acute coronary syndrome (NSTE-ACS), recurrent thrombotic events are more frequent in patients with type 2 diabetes mellitus (T2DM).

Materials And Methods: This exploratory study was aimed to evaluate quantitative and qualitative aspects of thrombus. In 28 patients with and without T2DM treated with aspirin and clopidogrel we assessed thrombus quantity using an ex-vivo chamber, platelet reactivity, thrombus ultrastructure and thrombus kinetics one week after NSTE-ACS.

Article Synopsis
  • The study focuses on improving awareness of hypoglycemia and counterregulation in adults with type 1 diabetes (T1D) through a treatment aimed at hypoglycemia avoidance.
  • Eighteen participants underwent various tests before and after a 6-month intervention, which involved education and different insulin therapies alongside glucose monitoring methods.
  • Results showed that after the intervention, participants had higher glucose levels at which they first felt hypoglycemic, indicating improved awareness, and their physiological responses to low glucose improved, although cognitive reaction times remained unchanged.

Background: Severe hypoglycaemia (SH) is one of the most feared complications of type 1 diabetes (T1DM) with a reported prevalence of nearly 40%. In randomized trials of Multiple Daily Injections (MDI) and Continuous Subcutaneous Insulin Infusion (CSII) therapy there is a possible benefit of CSII in reducing SH. However few trials have used basal insulin analogues as the basal insulin in the MDI group and individuals with established SH have often been excluded from prospective studies.
