Robot-assisted system found to be feasible for diagnostic cerebral angiography

by

Digital subtraction angiography remains the gold standard for diagnosing cerebrovascular diseases, including intracranial aneurysms, arteriovenous malformations, and arterial stenosis. However, the procedure requires operators to work under fluoroscopic guidance, resulting in prolonged exposure to ionizing radiation. To address this issue, vascular interventional robotic systems have been developed to allow operators to perform procedures remotely from … Read more

Hormonal imbalance and gut microbes linked to cognitive deficits in patients with PitNETs

by

Pituitary neuroendocrine tumors (PitNETs) are commonly associated with visual disturbances and endocrine abnormalities; however, many patients also experience cognitive deficits, particularly in memory, attention, and executive function, which significantly affect quality of life. Despite increasing recognition of this burden, the mechanisms underlying cognitive impairment remain unclear. Traditionally, cognitive changes have been attributed to tumor mass … Read more

Radiation from CT scans linked to future cancer risks in children and adults

by

Radiation from imaging could lead to lung, breast and other future cancers, with 10-fold increased risk for babies. CT scans may account for 5% of all cancers annually, according to a new study out of UC San Francisco that cautions against overusing and overdosing CTs. The danger is greatest for infants, followed by children and … Read more

Senolytic agent ABT-263 mitigates GI cancer risk after radiation exposure

by

A new research paper was published by Aging (Aging-US) on January 8, 2025, in Volume 17, Issue 1, titled “Senolytic agent ABT-263 mitigates low- and high-LET radiation-induced gastrointestinal cancer development in Apc1638N/+ mice.” Researchers Kamendra Kumar, Bo-Hyun Moon, Santosh Kumar, Jerry Angdisen, Bhaskar V.S. Kallakury, Albert J. Fornace Jr., and Shubhankar Suman from Georgetown University Medical Center explored whether a drug called ABT-263 … Read more
