Saliba W, et al. - In a large population-based cohort, researchers investigated the relationship of diabetes and glycated hemoglobin (HbA_1c) with the risk of intracerebral hemorrhage (ICH). On January 1, 2010, the computerized database of the largest health care provider in Israel was used to identify adult members aged 40 years or older and alive (297,486 with diabetes and 1,167,585 diabetes free). According to the findings, diabetes is linked to an increased risk of ICH directly related to the duration of diabetes. ICH and HbA_1c seem to have a J-shaped relationship, implying that increased risk could be associated with both poor control and extreme intensive diabetes control.
