Aneurysms of the interventricular membranous septum are a rare anatomical feature that can be detected incidentally on computed tomography or echocardiography. Such aneurysms can pose challenges in the treatment of patients with aortic valve stenosis. A case series of 2 patients with membranous septal aneurysms treated successfully with current-generation balloon-expandable and self-expanding transcatheter heart valves is presented here.

Importance: Most patients with locally advanced hepatocellular carcinoma (HCC) recur within the liver following systemic therapy.

Objective: To determine whether stereotactic body radiation therapy (SBRT) improves outcomes in patients with locally advanced HCC compared with sorafenib alone.

Design, Setting, And Participants: This multicenter phase 3 randomized clinical trial randomized patients with HCC 1:1 to sorafenib or SBRT followed by sorafenib, stratified by performance status, liver function, degree of metastases, and macrovascular invasion.

Trisomy of human chromosome 21 (Ts21) individuals present with a spectrum of low bone mineral density (BMD) that predisposes this vulnerable group to skeletal injuries. To determine the bone regenerative capacity of Down syndrome (DS) mice, male and female Dp16 and Ts65Dn DS mice underwent amputation of the digit tip (the terminal phalanx (P3)). This is a well-established mammalian model of bone regeneration that restores the amputated skeletal segment and all associated soft tissues.

Purpose Of Review: Abdominal pain due to cancer is a significant and debilitating symptom for cancer patients, which is commonly undertreated. Radiotherapy (RT) for the management of abdominal cancer pain is underused, with limited awareness of its benefit. This review presents a discussion on current precision RT options for the management of cancer pain in the abdomen.
