Endovascular repair of infrarenal abdominal aortic aneurysm combined with aneurysmectomy and interposition bypass for left common femoral artery aneurysm.

Femoral artery aneurysms (FAAs) can occur in some patients with abdominal aortic aneurysms. There is a lack of natural history studies in the published literature. Guidelines recommend FAA repair when symptomatic or larger than 2.

Hepatocellular Carcinoma Epigenetic Patterns Correspond to Differences in Ethnoracial Status and Treatment Response in a Single-Center Retrospective Study.

Purpose: To correlate epigenetic patterns with ethnoracial status and locoregional therapy (LRT) response in patients with hepatocellular carcinoma (HCC).

Materials And Methods: DNA and RNA were extracted from 47 distinct formalin-fixed paraffin-embedded tumor samples from 42 patients with HCC (n = 14 Black, n = 19 White, n = 9 Hispanic). LRT response was determined using computed tomography (CT) or magnetic resonance (MR) imaging 3 months posttreatment of 35 tumors (n = 22 complete response, n = 13 retreatment candidates).

Observational Study of the Association between Air Cadmium Exposure and Prostate Cancer Aggressiveness at Diagnosis among a Nationwide Retrospective Cohort of 230,540 Patients in the United States.

Although studies have investigated cadmium and prostate cancer (PC) incidence and mortality, the role of cadmium in PC progression might be more clinically relevant. In this observational study, we assessed the association between air cadmium exposure and PC aggressiveness, with PC stage defined as metastatic or localized and Gleason grade defined as high (Gleason score ≥ 8) or low (Gleason score ≤ 6) among PC patients from the 2010-2014 US Surveillance, Epidemiology, and End Results database. The 2005 and 2011 National Air Toxics Assessment provided county-level air cadmium concentrations.

Hydrogel Micropost Arrays with Single Post Tunability to Study Cell Volume and Mechanotransduction.

The extracellular matrix varies considerably in mechanical properties at the microscale. It remains unclear how cells respond to these properties, in part, due to lack of tools to create precisely defined microenvironments in a discrete manner. Here, freeform stereolithography is leveraged to control the placement and elastic modulus of individual hydrogel microposts that serve as discrete matrix signals to interface with cells.
