Aim: Our study aims to assess the knowledge of hemoglobin A1c (HbA1c) and glycemic control in patients with diabetes mellitus (DM) at an urban academic institution.
Methods: This was a retrospective cross-sectional study that included a survey of 100 adult patients with DM. Our patient cohort was divided into those with recent HbA1c < 8.0% and those with HbA1c ≥ 8.0% for subgroup analysis.
Results: The majority (71%) of patients correctly defined HbA1c and half were aware of their HbA1c target, but they were unable to correlate the correct average blood glucose for an HbA1c level of 7%. Worse control, defined as an HbA1c level of ≥ 8%, was associated with co-morbid disease, but was not associated with understanding HbA1c definition, target or socioeconomic disparities. Perceived glycemic control was congruent with the actual control in 46% of our patients. Ninety percent of those with HbA1c ≥ 8% perceived their control to be better than it actually was, and 97% of those with HbA1c < 8% perceived their control worse than it actually was (P < 0.00001).
Conclusion: Although most patients knew the definition of HbA1c, they were unable to correlate HbA1c with average blood sugar. There remain opportunities to increase education for this vulnerable population with co-morbid disease on the use of the HbA1c disease marker as an education tool.

The triglyceride-glucose index as a surrogate measure to assess glycemic control in type 2 diabetes patients.
Ir J Med Sci

Background: It has been revealed that the potential utility of the triglycerides and glucose (TyG) index as an effective option for assessing glycemic control; however, evidence in this field is still scarce.
Aims: The goal of this study was to investigate the diagnostic accuracy of the TyG index, as an alternative option, to detect inadequate glycemic control in patients with type 2 diabetes (T2D).
Methods: Men and women between 30 and 60 years of age diagnosed with type 2 diabetes were included in a cross-sectional study.
Subtypes of Insulin Restriction in Diabetes Management: A Systematic Review.
Curr Diab Rep
January 2025
Department of Psychological Sciences, University of California, Merced, CA, USA.
Purpose Of Review: Insulin restriction is commonly studied as a form of disordered eating, but people may restrict insulin for many reasons. This systematic review examined how insulin restriction has been conceptualized and measured, and its associated predictors and outcomes.
Recent Findings: Forty-seven unique articles measured non-specified insulin restriction (IR), insulin restriction specifically for weight control (IRWC), or both.
The Effect of HBV Therapy on Glycemic Control in HBV-Infected Patients With Diabetes: A 90-day Multicenter Study.

Patients with diabetes are at increased risk of HBV infection; however, the effects of HBV infection and anti-HBV therapy on the management of type 1 diabetes (T1D), type 2 diabetes (T2D), and latent autoimmune diabetes in adults (LADA) remain unclear. From 2016 to 2023, we recruited a multicenter cohort of 355 HBV-infected inpatients, including 136 with T1D, 140 with T2D, and 79 with LADA. The control group included 525 HBV-uninfected inpatients, comparing 171 with T1D, 204 with T2D and 150 with LADA.

Aims: The aim of this study was to assess postprandial glycaemic outcomes using automated insulin delivery with faster acting insulin aspart (FIA) or standard insulin aspart (SIA) over 4 weeks in youth (aged 10-18 years) with type 1 diabetes.
Materials And Methods: We undertook a secondary analysis of postprandial glycaemic outcomes from a double-blind, randomised, crossover study comparing FIA to SIA using an investigational version of MiniMed™ 780G. Endpoints included postprandial time in tight range (70-140 mg/dL; TITR), postprandial glucose excursions and peak glucose, and incremental area under curve (iAUC).
The use of incretin analogues has emerged in recent years as an effective approach to achieve both enhanced insulin secretion and weight loss in type 2 diabetes (T2D) patients. Agonists which bind and stimulate multiple receptors have shown particular promise. However, off target effects, including nausea and diarrhoea, remain a complication of using these agents, and modified versions with optimized pharmacological profiles and/or biased signaling at the cognate receptors are increasingly sought.
