Blood-based tests show promise for colorectal cancer screening but follow-up challenges persist

A study led by investigators at the UCLA Health Jonsson Comprehensive Cancer Center found that while blood-based tests offer a more convenient option for colorectal cancer screening, only 49% of patients completed a follow-up colonoscopy within six months, and just 56% did so at any point during the two-year study period.

Microcone-enhanced microfluidic device captures circulating tumor cells efficiently

Circulating tumor cells (CTCs) refer to cancer cells that have broken off from a primary tumor. These tumor cells can travel through the blood in the circulatory system and lodge themselves in other organs to cause secondary tumors.

New blood markers predict kidney disease and mortality in diabetes

Kidney complications in diabetes often progress silently, putting patients at risk of life-threatening outcomes long before any symptoms appear. Identifying individuals with diabetes who are at risk of rapid kidney function decline or early death has challenged doctors for decades, with traditional markers like serum creatinine and urinary albumin falling short of accurately predicting these risks.

Scientists uncover new brain mechanism driving PTSD and potential counter-drug

Did you know that patients with post traumatic stress disorder (PTSD) often struggle to forget traumatic memories, even long after the danger has passed? This failure to extinguish fear memories has long puzzled scientists and posed a major hurdle for treatment, especially since current medications targeting serotonin receptors offer limited relief for only a subset of patients.
