Objective: We investigated whether prepregnancy BMI (prePregBMI) in women with obesity was associated with differential DNA methylation (DNAm) in cord blood (CB) and whether DNAm may mediate the association of prePregBMI and early childhood BMI z score (BMIz).

Methods: From the Treatment of Obese Pregnant Women (TOP) study, 232 mother-child pairs were included. We conducted an epigenome-wide association study on prePregBMI and CB DNAm (450k array), followed by causal mediation analyses to test whether DNAm may mediate effects of prePregBMI on  BMIz at age 36 months (BMIz36).

Regular physical activity and exercise (PA) are cornerstones of diabetes care for individuals with type 1 diabetes. In recent years, the availability of automated insulin delivery (AID) systems has improved the ability of people with type 1 diabetes to achieve the recommended glucose target ranges. PA provides additional health benefits but can cause glucose fluctuations, which challenges current AID systems.

Article Synopsis
  • The study aimed to compare plasma glucose responses during moderate-intensity exercise in adults with type 1 diabetes (T1D) using an automated insulin delivery system, both with and without glucagon injection.
  • Ten participants underwent two exercise trials: one with 150-μg glucagon and one without, measuring glucose levels and other biomarkers during and after exercise.
  • Results showed that participants maintained stable blood glucose levels in both conditions, indicating that glucagon was unnecessary to prevent hypoglycemia during moderate-intensity exercise in this particular group.

Article Synopsis
  • Glycemic control in ICU patients is crucial as dysglycemia can lead to negative outcomes, prompting interest in using Continuous Glucose Monitoring (CGM) systems for better monitoring in these settings.
  • A systematic review identified 2133 studies on CGM accuracy, narrowing it down to 96 relevant studies that primarily focused on adult patients and various CGM systems, with most studies indicating varied levels of accuracy.
  • The review found that the accuracy of CGM devices differed based on the type of device and reference methods used, with intravascular CGM showing better accuracy compared to subcutaneous systems, particularly during episodes of hypoglycemia.

Increased plasma levels of glucagon (hyperglucagonemia) promote diabetes development but are also observed in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). This may reflect hepatic glucagon resistance toward amino acid catabolism. A clinical test for measuring glucagon resistance has not been validated.

Article Synopsis
  • The study examined how missed or late meal boluses (MLBs) affect glucose levels in children and teens with type 1 diabetes using automated insulin delivery (AID) systems.
  • It involved 189 participants, averaging 13 years old, and discovered that each additional MLB per day led to a significant decrease in time spent within the target glucose range (TIR).
  • The findings highlight the critical need for proper bolus timing to improve glycemic control, suggesting future research into tools that can assist with managing MLBs.

Introduction: Glucagon receptor agonism is currently explored for the treatment of obesity and metabolic dysfunction-associated steatotic liver disease (MASLD). The metabolic effects of glucagon receptor agonism may in part be mediated by increases in circulating levels of Fibroblast Growth Factor 21 (FGF21) and Growth Differentiation Factor 15 (GDF15). The effect of glucagon agonism on FGF21 and GDF15 levels remains uncertain, especially in the context of elevated insulin levels commonly observed in metabolic diseases.

Aims/hypothesis: As a result of early loss of the glucagon response, adrenaline is the primary counter-regulatory hormone in type 1 diabetes. Diminished adrenaline responses to hypoglycaemia due to counter-regulatory failure are common in type 1 diabetes, and are probably induced by exposure to recurrent hypoglycaemia, however, the metabolic effects of adrenaline have received less research attention, and also there is conflicting evidence regarding adrenaline sensitivity in type 1 diabetes. Thus, we aimed to investigate the metabolic response to adrenaline and explore whether it is modified by prior exposure to hypoglycaemia.

The physical and psychological benefits of exercise are particularly pertinent to people with type 1 diabetes (T1D). The variability in subcutaneous insulin absorption and the delay in offset and onset in glucose lowering action impose limitations, given the rapidly varying insulin requirements with exercise. Simultaneously, there are challenges to glucose monitoring.

By reducing carbohydrate intake, people with type 1 diabetes may reduce fluctuations in blood glucose, but the evidence in this area is sparse. The aim of this study was to investigate glucose metrics during a one-week low-carbohydrate-high-fat (HF) and a low-carbohydrate-high-protein (HP) diet compared with an isocaloric high-carbohydrate (HC) diet. In a randomized, three-period cross-over study, twelve adults with insulin-pump-treated type 1 diabetes followed an HC (energy provided by carbohydrate: 48%, fat: 33%, protein: 19%), HF (19%, 62%, 19%), and an HP (19%, 57%, 24%) diet for one week.
