Abstract

Aims To investigate the independent association between long-term glycemic variability, measured as the coefficient of variation (CV) of HbA1c, and the presence of diabetic retinopathy (DR) in a cohort of adults with diabetes within a system-atic eye screening program.

Methods This study screened 379 adults with type 1 and type 2 diabetes. Long-term glycemic variability was calculated as the CV of serial HbA1c measurements. DR was assessed via dilated fundus photography. The association between HbA1c CV and DR was analyzed using multivariable logistic regression adjusting for confounders.

Results DR incidence of 12.4%, mostly mild non-proliferative. The median HbA1c CV was 7.0% (53 mmol/mol). In unad-justed bivariate analysis, the incidence of mild DR was higher in the low- glycemic variability group (CV<5%) compared to the high- glycemic variability group. However, the multivariable logistic regression analysis revealed that higher HbA1c CV was independently associated with the presence of DR (β=0.643, P=0.042), alongside diabetes duration (P<0.001) and age (P<0.001).

Conclusions In conclusion, in a cohort of individuals with both type 1 and type 2 diabetes and a low incidence of DR, long-term glycemic variability, estimated as HbA1c CV, was independently associated with an increased risk of this complication.

【Abstract】 Acne vulgaris （abbreviated as acne） is a common aesthetic ⁃ impairing dermatological disease that markedly affects appearance, and is characterized by diverse clinical manifestations. At present, there are various grading systems for acne severity, while there is still a lack of unified standards for objectively assessing disease severity to guide treatment selection and scientifically evaluating the efficacy of acne therapies, which are also highly concerned issues for clinicians. To address this, the Acne Study Group of China Dermatologist Association, the Dermatology Professional Committee of Chinese Research Hospital Association, and the Acne Study Group of Dermatology and Venereology Professional Committee of Chinese Association of Integrative Medicine organized a group of experts in the field of acne diagnosis and treatment in China to develop the "Chinese expert consensus on clinical severity grading and therapeutic evaluation of acne vulgaris" after extensive discussions, aiming to provide a reference for dermatologists in clinical practice.
