In elderly patients at high risk for cardiovascular disease, long sleep duration as well as persistent insomnia were significantly associated with higher visit-to-visit BP variability. Long sleep duration and persistent insomnia each had synergetic interactions with carotid artery stiffness and with visit-to-visit BP variability.

Digital breast tomosynthesis (DBT) imaging uses two types of image reconstruction. methods, i.e., filtered back projection (FBP) method and an iterative reconstruction (IR) method. Although the effect of the difference in the image reconstruction method on the image quality has been reported, these studies were performed using different apparatus or conditions. In this study, we examined the effect of image reconstruction on the image quality using the same equipment under the same conditions. Method: We measured reflection artifact, sharpness, signal detection ability, and granularity using DBT-photographed images by both the FBP and the IR methods. Result: Although the difference between the two methods was subtle for granularity, IR was found to be superior to FBP in all items tested. Conclusion: This study suggested the clinical usefulness of IR over FBP.

Infected aortic aneurysms are difficult to treat and, in the absence of aortic resection, are almost always fatal. We report a case of an infected aortic aneurysm cured by antibiotic treatment alone. In this case, the intramural abscess was supposed to be naturally resolved by the discharge of pus into the vascular lumen and infection was suppressed by the antibiotic treatment.
