Shikama M, Sonoda N, Morimoto A, et al. - Researchers conducted this cross-sectional study to explore the connection between the percentage of crossing capillaries in the finger nailfold and diabetic retinopathy (DR) in patients with type 2 diabetes mellitus. Between May and October 2019, 108 type 2 diabetes mellitus patients, aged 40 to 75 years, who attended the outpatient diabetic clinic at Osaka University Hospital, Osaka, Japan, were analyzed. Using multivariable logistic regression, the connection between the tertile of the percentage of the crossing capillary and DR were analyzed. In patients with type 2 diabetes mellitus, a higher percentage of crossing capillaries in the nailfold was linked to a higher risk of DR, independent of traditional risk and inhibiting factors including age, gender, duration of diabetes, glycated hemoglobin, systolic blood pressure, BMI, and the use of renin–angiotensin system inhibitor and antilipidemic medication.
