Risk of retinopathy and nephropathy did not differ at HbA1c levels <6.5% but increased for severe hypoglycaemia compared with HbA1c levels 6.5-6.9%. The risk for severe complications mainly occurred at HbA1c levels >8.6%, but for milder complications was increased at HbA1c levels >7.0% (BMJ)

Distinct trajectories of HbA1c in newly diagnosed Type 2 diabetes from the DPV registry using a longitudinal group‐based modelling approach
Four subgroups with distinct HbA1c trajectories were determined in newly diagnosed Type 2 diabetes using a group‐based modelling approach. Approximately one‐third of people with newly diagnosed Type 2 diabetes need either better medication adherence or earlier intensification of glucose‐lowering therapy (Diabetic Medicine)
Adjunct Therapy in Type 1 Diabetes: A Survey to Uncover Unmet Needs and Patient Preferences Beyond HbA1c Measures
This survey highlights the importance of measures beyond HbA1c, such as treatment simplification and TIR, and patient preference for adjunct therapies that help address unmet needs in type 1 diabetes treatment (Diabetes Technology and Therapeutics)
The association between fasting plasma glucose and glycated hemoglobin in the prediabetes range and future development of hypertension
Our study demonstrates that FPG in the prediabetes range, albeit not glycated hemoglobin, is independently and significantly associated with future development of HTN. Therefore, our findings further highlight the pivotal predictive role of IFG for HTN development as opposed to the limited independent role of abnormal HbA1c levels (Cardiovascular Diabetology)
A View Beyond HbA1c: Role of Continuous Glucose Monitoring
The CGM metrics provide a more personalized approach to diabetes management and resolve most of the limitations of HbA1c (Diabetes Therapy)
Double‐blind, randomized clinical trial comparing the efficacy and safety of continuing or discontinuing the dipeptidyl peptidase‐4 inhibitor sitagliptin when initiating insulin glargine therapy in patients with type 2 diabetes
When initiating insulin glargine therapy, continuation of sitagliptin, compared with discontinuation, resulted in a clinically meaningful greater reduction in HbA1c without an increase in hypoglycaemia (Diabetes, Obesity and Metabolism)
Changes in Screening Practices for Prediabetes and Diabetes Since the Recommendation for Hemoglobin A1c Testing
As we observed in 2004, rates of screening are high. HbA1c is still used less frequently than glucose for screening but is more likely to result in a clinical diagnosis. Evidence to support guidelines to define the role of random glucose screening, including definition of appropriate cut points and follow-up, is needed (Diabetes Care)
Association between full monitoring of biomedical and lifestyle target indicators and HbA1c level in primary type 2 diabetes care: an observational cohort study (ELZHA-cohort 1)
This study shows that in a care group setting, fully monitored patients had significantly lower HbA1c levels compared with incompletely monitored patients (BMJ Open)
Beyond HbA1c: using continuous glucose monitoring metrics to enhance interpretation of treatment effect and improve clinical decision‐making
This review presents several clinical scenarios of glycaemic outcomes from CGM data that can be analysed to describe glycaemic variability and its attendant risks of hyperglycaemia and hypoglycaemia, moving towards relevant interpretation of the complex CGM data streams (Diabetic Medicine)
Preventing misdiagnosis of diabetes in the elderly: age-dependent HbA1c reference intervals derived from two population-based study cohorts
The present study confirmed the previously observed increase of HbA1c with increasing age in non-diabetic individuals. As a consequence age-dependent reference values for HbA1c were derived from two large and well defined reference populations. Implementation of them into daily practice may improve patient care and diagnosis of diabetes and reduce the risk of misdiagnosis and subsequent overtreatment of diabetes in elderly patients (BMC Endocrine Disorders)
Text‐message responsiveness to blood glucose monitoring reminders is associated with HbA1c benefit in teenagers with Type 1 diabetes
Teenagers with Type 1 diabetes who responded to text reminders on ≥50% of days over 18 months experienced clinically significant glycaemic benefit. There remains a need to tailor interventions to maintain teenager engagement and optimize improvements (Diabetic Medicine)
Relationship between HbA1c and all-cause mortality in older patients with insulin-treated type 2 diabetes: results of a large UK Cohort Study
Both low and high HbA1c were associated with increased all-cause mortality, among older patients with insulin-treated T2D. This cohort study supports the need for individualisation of care and suggests better outcomes with HbA1c levels around 6.5–7.4% and markedly excess risk with HbA1c > 11% (Age and Ageing)
Double‐blind, randomized clinical trial assessing the efficacy and safety of early initiation of sitagliptin during metformin up‐titration in treatment of patients with type 2 diabetes: the CompoSIT‐M Study
In participants not at HbA1c goal on a sub‐maximal dose of metformin, addition of sitagliptin at the time of metformin dose up‐titration improved glycemic response and HbA1c goal attainment with similar safety and tolerability compared to metformin up‐titration alone (Diabetes, Obesity and Metabolism)
Investigating the Association Between Baseline Characteristics (HbA1c and Body Mass Index) and Clinical Outcomes of Fast-Acting Insulin Aspart in People with Diabetes
In participants with T1D and T2D, treatment differences (for change in HbA1c and overall hypoglycaemia) between mealtime faster aspart and insulin comparators were similar to the corresponding overall analysis across baseline HbA1c and BMI subgroups. The finding of a lower total daily insulin dose in participants with obesity (BMI > 30 kg/m2) and T1D treated with faster aspart, versus those treated with IAsp, may warrant further investigation (Diabetes Therapy)
HbA1c screening in the community: Lessons for safety and quality management of a point of care programme
POC testing must be conducted within stringent quality assurance processes prior to and while in use. Within such a system, POC testing for HbA1c can be sufficiently accurate for screening and diagnosis of diabetes (Primary Care Diabetes)
Commencing insulin glargine 100 U/mL therapy in people with type 2 diabetes: Determinants of achievement of HbA1c goal <7.0%
Baseline HbA1c was the strongest determinant for achieving target HbA1c <7.0% by supplementary Gla‐100 therapy while sex and BMI were also useful indicators. However, age and C‐peptide levels at baseline did not predict glycaemic response to the introduction of basal insulin (Diabetes, Obesity and Metabolism)
Effects of intensive interventions compared to standard care in people with type 2 diabetes and microalbuminuria on risk factors control and cardiovascular outcomes
Apart from blood pressure outcomes, there was no evidence that intensive interventions improve or worsen HbA1c, total cholesterol, LDL, triglycerides, urinary albumin excretion rate, risk of cardiovascular or mortality outcomes in people with type 2 diabetes and microalbuminuria (Diabetes Research and Clinical Practice)
Visit-to-visit HbA1c variability is inversely related to baroreflex sensitivity independently of HbA1c value in type 2 diabetes
Visit-to-visit HbA1c variability was inversely related to BRS independently of the mean HbA1c in patients with T2DM. Therefore, visit-to-visit HbA1c variability might be a marker of reduced BRS in T2DM (Cardiovascular Diabetology)
FRAX tool in type 2 diabetic subjects: the use of HbA1c in estimating fracture risk
We propose a correction factor derived from HbA1c that could enhance the predictive ability of fracture risk estimated by the FRAX algorithm in subjects with T2DM (Acta Diabetologica)
High Proportion of Type 2 Diabetes Adults with Poor Glycated Hemoglobin Perceived that Their Diabetes Control was “Excellent”
This study demonstrates discordance between perception of diabetes control and HbA1C which may hinder effective diabetes care (Canadian Journal of Diabetes)
