ABSTRACT
The relationship between Sulfonylureas(SUs) and cardiovascular (CV) risks has attracted great attention.Previous studies have illustrated that some SUs increase CV risk in type 2 diabetes (T2DM) patients;while others do not.Clinical studies have found that the CV risks of different SUs may be different.Compared with other SUs;glimepiride and gliclazide may have lower CV risks.Here we reviewed evidence-based CV safety of SUs and the recent research progress.
ABSTRACT
Objective To investigate how many probably benign lesions on ultrasound(US) fulfilled the published criteria and to evaluate how clinical and personal factors influenced the categorization of breast lesions.Methods A total of 487 lesions in 487 women with more than 12 months follow-up after the initial category 3 assessment on US were included.The initial US images were retrospectively reviewed according to previously published criteria,and evaluated several factors that could influence the characterization of breast lesions in clinical practice such as age,multiplicity,palpability,radiologist 's experience,and lesion size.Results Of 487 lesions,479 (98.36%) were benign and 8 (1.64%) were malignant.Of 487 lesions,203(41.68%) including 8 malignancies were reassessed as category 4.If strict criteria had been applied at initial US examination,the positive biopsy rate would have been only 3.94% (8/203) and 96.06% (195 of 203) biopsies would have been unnecessary.Lesions in women 40 years or older and multiple lesions were more frequently reassessed as category 4 (P = 0.008 and P = 0.006,respectively).The presence of palpability,lesion size,and the radiologist 's experience did not significantly influence the categorization of breast lesions on US.Of 487 probably benign lesions,41.68 % could be classified as category 4 lesions when strict criteria were applied in initial practice.Conclusions The multiplicity of the lesion and the patient 's age were found to have a significant influence on the classifcation of probably benign solid masses.
