BU researcher examines clinicians’ attitudes towards major changes from the 2020 ACS Cervical Cancer Screening Guidelines

(Boston)—Nearly all cervical cancers are caused by the human papillomavirus (HPV). New evidence has led to dramatic changes in cervical cancer screening recommendations over the past 20 years. In 2020, the American Cancer Society (ACS) released updated guidelines for cervical cancer screening. The main changes to current practices were to initiate screening at age 25 instead of age 21 and to screen using primary HPV testing rather than cytology (PAP test) alone or in combination with HPV testing. Since adoption of guidelines often occurs slowly, understanding clinician attitudes is important ...

Coronary artery calcium score predictive of heart attacks, strokes

OAK BROOK, Ill. – Coronary artery calcium scoring with CT can identify symptomatic patients with a very low risk of heart attacks or strokes, according to a new study published today in Radiology, a journal of the Radiological Society of North America (RSNA). Researchers said the findings may one day help some patients with stable chest pain avoid invasive coronary angiography. Coronary artery calcium scoring with CT was developed to noninvasively measure the amount of calcium in the arteries of the heart. Higher scores are linked with atherosclerosis, a buildup of plaque in the arteries. A score of 1 to 399, for instance, suggests a moderate amount of plaque, while 400 ...
