Are target lesion ulceration and arch calcification associated with increased incidence of carotid stenting-associated ischemic lesions in octogenarians?
Increased prevalences of severe aortic arch calcifications and target lesion ulceration are associated with an increased risk for magnetic resonance DWI-detected embolic events during CAS. Because in our study arch calcification and target lesion ulceration were more prevalent in octogenarians, this association may explain the increased risk of CAS in the elderly.
This study documents for the first time high levels of HIV RNA in preejaculate fluid. However, none of the men on stable HAART with undetectable blood viral load had HIV RNA in preejaculate, even though many had detectable HIV in semen. The urethral glands do not appear to be a principal source of HIV in men on suppressive HAART.
