Association between an elevated inter-arm systolic blood pressure difference, the ankle-brachial index, and mortality in patients with diabetes mellitus.

Objectives: To estimate the prevalence of an inter-arm blood pressure difference greater than 10mmHg in patients with type 2 diabetes, and the association of this measurement with the presence of a low ankle-brachial index and mortality at 5-year follow-up.

Method: A validated blood pressure measurement protocol was used. The blood pressure was calculated for each arm to obtain mean systolic differences.

Study of abnormal adrenal receptors in subjects with ACTH-independent Cushing's syndrome and nodular adrenal hyperplasia.

Introduction: ACTH-independent Cushing's Syndrome (AICS) accounts for 15-20% of cases of Cushing's syndrome, with <1% due to abnormal receptors. Our aim is to study the presence of abnormal receptors in subjects diagnosed with AICS with nodular adrenal hyperplasia in a 14-year period (2002-2016), as well as its clinical-biological and evolutive characteristics.

Material And Methods: A multicentre descriptive study of a 15-case series of AICS with nodular adrenal hyperplasia (study period: 2002-2016).

Accuracy of three hemoglobin A1c point-of-care systems for glucose monitoring in patients with diabetes mellitus.

Objectives: Use of hemoglobin A1c point-of-care devices in physician offices provides immediate results and reduces inconveniences for the patients. We compared the analytical performances of 3 point-of-care HbA1c analyzers to high pressure liquid chromatography (HPLC).

Material And Methods: We preselected a pool of 40 EDTA-preserved whole blood samples from our laboratory with HbA1c results obtained by HPLC (mean 6.

Accuracy of ankle-brachial index obtained by automated blood pressure measuring devices in patients with diabetes mellitus.

Background: Upper arm automated blood pressure devices are widely available and could be used to estimate the ankle-brachial index.

Methods: We conducted a trial to determine the equivalence of ankle-brachial index estimated by an upper arm blood pressure measuring device as index method compared to the handheld Doppler method as the reference standard. A total of 110 patients with diabetes mellitus were sequentially examined by two methods.

Misclassification of subjects with insulin resistance and associated cardiovascular risk factors by homeostasis model assessment index. Utility of a postprandial method based on oral glucose tolerance test.

Different methods are available for assessing insulin sensitivity in the fasting state. However, insulin resistance (IR) is initially a postprandial disturbance; and usually, when basal (fasting) disturbance appears, the process has been in progress for some time. Our aim was to investigate if a postprandial measurement, performing an oral glucose tolerance test (OGTT), is more sensitive than fasting values.
