Neurovascular mechanisms of cognitive aging: Sex-related differences in the average progression of arteriosclerosis, white matter atrophy, and cognitive decline.

Arterial stiffness (arteriosclerosis) has been linked to heightened risks for cognitive decline, and ultimately for Alzheimer's disease and other forms of dementia. Importantly, neurovascular outcomes generally vary according to one's biological sex. Here, capitalizing on a large sample of participants with neuroimaging and behavioral data (N = 203, age range = 18-87 years), we aimed to provide support for a hierarchical model of neurocognitive aging, which links age-related declines in cerebrovascular health to the rate of cognitive decline via a series of intervening variables, such as white matter integrity.

Non-Surgical Bleeding and Transurethral Resection of the Prostate (TURP) Syndrome after TURP Surgery: A Case Report and Literature Review.

Patients undergoing transurethral resection of the prostate (TURP) surgery can develop TURP syndrome and post-TURP bleeding. Post-TURP bleeding can be surgical, from arteries or venous sinuses, or non-surgical, due to coagulopathy preventing clot formation. Non-surgical post-TURP bleeding may be due to high concentrations of urokinase and tissue plasminogen activator (tPA) in the urine that cause fibrinolytic changes and increase bleeding risk.

Morphologic features of prostate cancer-encased native vessels: An image analysis study.

Background: Vasculature plays a crucial role in the progression of prostate cancer (PC). Changes to the prostatic native vessels have not been studied since 2000 when Garcia et al. demonstrated marked media hypercellularity and increased artery thickness in prostatic native arteries within PC.

Clinicopathologic Characterization of Kaposi Sarcoma on the Foot and Ankle: Analysis of 11 Patients Seen in Our Clinics.

Background: Kaposi sarcoma (KS) has multiple clinical variants, and most frequently presents on the lower extremities. Anti-human immunodeficiency virus (HIV) therapy has significantly reduced the incidence of KS. However, KS is still prevalent in both HIV-infected and HIV-uninfected patients.
