Blood test can spot early liver transplant issues to prevent organ failure

While testing of colorectal cancer tumors for mismatch repair (MMR) defects has been recommended for years, the majority of patients with abnormal results do not complete the next steps, including genetic testing. Skipping those steps can cause missed cancer diagnoses and unnecessary costs, as explained in a Yale study recently published in the journal Clinical Gastroenterology and Hepatology.

COVID-19 appears to be on the rise in some parts of California as a new, highly contagious subvariant—featuring "razor blade throat" symptoms overseas—is becoming increasingly dominant.

Doomscrolling. Instagram obsessions. Mindless YouTube video viewing.

From 2016 to 2023, there was an increase in the mean age of mothers at first birth and at higher-order births, according to the June 13 National Vital Statistics Reports.

Allison Harvey knew she'd have to study hard when she enrolled in an 11-week course on parenting techniques earlier this year. A UC Berkeley professor of psychology who researches memory, habits and sleep, Harvey printed her notes and meticulously completed each week's homework. She engaged with the instructors, who were also well-respected clinical psychologists. And she was far more engaged than her classmates, including her husband.

In the late 1980s, researchers identified a rare genetic mutation that leads to Alzheimer's disease, and yet drugs developed in response haven't slowed Alzheimer's progression nearly to the degree researchers had hoped. In the 1990s, scientists dreamed of biological tests—such as brain scans or blood tests—to diagnose psychiatric conditions like depression, and yet diagnoses are still based on symptoms alone.

Rat lungworm disease is on the rise in eastern Australia in dogs—and there have even been recorded cases in humans, including two known lethal incidents. Caused by a parasite naturally found in rats, the disease requires ongoing monitoring to ensure it is controlled and doesn't pose a public health threat.

Scientists have discovered clues that may explain why some treatments stop working for people with bowel cancer—causing about 16,800 deaths in the U.K. every year.

The number of older women living with a history of breast cancer in the U.S. is growing, which is due to new diagnoses in patients over 65 and because many women diagnosed at a younger age are living longer.

Treating rare diseases can be complicated at the best of times, and it gets even more complicated when different patients with the same disease exhibit different symptoms. Now, researchers from Japan have reported a cellular signature that might explain why some patients with autoimmune disease are stable while others face life-threatening complications.

Vaccination experts recently fired by Donald Trump's administration sounded the alarm in a Monday editorial, saying they were "deeply concerned" by the actions of a US health secretary known for his vaccine skepticism.

What if people could detect cancer and other diseases with the same speed and ease as a pregnancy test or blood glucose meter? Researchers at the Carl R. Woese Institute for Genomic Biology are a step closer to realizing this goal by integrating machine learning-based analysis into point-of-care biosensing technologies.

Despite overall progress in bringing down low birthweight numbers across India over the past 30 years, rates remain stubbornly high in certain states, with Uttar Pradesh, Bihar, Maharashtra, and West Bengal accounting for almost half of all such births, finds research published in BMJ Global Health.

Researchers at VCU Massey Comprehensive Cancer Center have developed a novel algorithm that could provide a revolutionary tool for determining the best options for patients—both in the treatment of cancer and in the prescription of medicines.

As concern grows over racial bias in common medical tools like pulse oximeters, a new study shows that smartphones may offer a simple, accessible way to help correct the problem. Researchers at Brown University and Morgan State University have developed a method for using smartphone cameras to objectively measure skin tone, a factor known to affect the accuracy of pulse oximetry—the technique that monitors oxygen levels through the skin.

A study published in the Annals of Internal Medicine estimates the potential effects on Medicaid enrollment, uninsurance, financial strain, health care access, and health outcomes from potential Medicaid budget cuts being considered in Congress, including the House reconciliation bill advanced in May.

Systemic sclerosis (SSc) is a severe autoimmune disease with complex genetic causes. Some genetic contributors have been identified, but others remain unknown, which has impeded development of targeted treatments. In a new study published in Annals of the Rheumatic Diseases, researchers at Baylor College of Medicine and collaborating institutions used complementary approaches that integrate exome sequencing and evolutionary action machine learning to identify protein changes and their associated mechanisms in SSc.

Multiple sclerosis (MS) affects an estimated 2.3 million people worldwide. Approximately 80% of people with MS have inflammation in the cerebellum, the part of the brain that helps control movement and balance, potentially leading to tremors, poor coordination, and trouble with motor control. These problems often persist and can worsen over time, as the cerebellum gradually loses healthy brain tissue.
