A quarter of teens with autism go undiagnosed, researchers find

About a quarter of 16-year-olds with autism spectrum disorder (ASD) have yet to receive a formal diagnosis, according to research from Rutgers. [...]

Liquid biopsy may help identify which patients with non-small cell lung cancer will benefit most from radiation

A novel liquid biopsy test may help determine which patients with non-small cell lung cancer that has spread beyond the lungs are most likely to benefit from targeted, high-dose radiation, rather than drug-based therapy, a new study suggests. Findings were presented at the American Society for Radiation Oncology (ASTRO) Annual Meeting and published in npj Precision Oncology. [...]

MDMA increases feelings of connection during conversation, showing promise for therapy

MDMA, commonly known as ecstasy, is a recreational psychedelic drug often used at parties and dance clubs because it creates feelings of closeness and social connection with others. Because of this "empathogenic" effect, researchers are also interested in its potential use as a complement to traditional talk therapy. In fact, two recent successful clinical trials support the use of MDMA-assisted therapy as a treatment for post-traumatic stress disorder (PTSD). [...]

Study shows how 'superbacteria' were prevented from spreading in a large tertiary hospital

Rapid identification of patients contaminated by "superbacteria" known as "carbapenem-resistant Enterobacteriaceae" (CRE), with early isolation of these patients, reduces transmission in hospital emergency departments. However, keeping them in the emergency room (ER) for more than two days undermines containment because it increases the risk of infection via colonization. [...]

Progress in the fight against resistance in metastatic breast cancer

A team of researchers at the Medical University of Vienna has discovered that dormant tumor cells surviving chemotherapy can be targeted through the inhibition of a specific protein called P-glycoprotein (P-gp). This discovery opens up new possibilities for delaying relapse and is particularly relevant for aggressive triple-negative breast cancer (TNBC), for which there are currently few effective treatments. [...]

Calls for verbal abuse of children by adults to be formally recognized as form of child maltreatment

A new systematic review by researchers at UCL and Wingate University has highlighted the importance of identifying childhood verbal abuse by adults as a standalone subtype of child maltreatment, to ensure targeted prevention and address the lasting harm it can inflict. [...]

Study indicates possible link between chronic stress and Alzheimer's disease

Researchers from Karolinska Institutet have published a study in Alzheimer's Research & Therapy that addresses possible associations between chronic stress, mild cognitive impairment and Alzheimer's disease. The study shows how people aged between 18 and 65 with a previous diagnosis of chronic stress and depression were more likely than other people to be diagnosed with mild cognitive impairment or Alzheimer's disease. [...]

Is your thumb pain de Quervain's tenosynovitis?

De Quervain's tenosynovitis (pronounced da-KWUHR-vanes teena-sine-ah-VITE-us) is a complicated name for a condition that's been referred to as "mother's thumb," "mommy wrist" and "gamer's thumb"—all associated with repetitive use of the hands and wrist. It is a condition that causes extreme pain in the wrist and thumb area. While the exact cause is not known, Dr. Sanjeev Kakar, a Mayo Clinic orthopedic surgeon, says that there are specific treatment options that can help. [...]

Tips to protect long-term brain health

There is a growing understanding of the role lifestyle choices play in preventing and slowing the progression of cognitive decline. While we await new treatments for Alzheimer's disease and other age-related dementias, emerging research can offer some advice for keeping our brains healthy and sharp. [...]

Researchers find education and occupation influence cardiovascular health and mortality

Cardiovascular diseases such as heart attacks and strokes are the most common cause of death worldwide. According to the World Health Organization (WHO), they account for about 18 million deaths each year. The causes of cardiovascular disease are diverse and complex. International studies suggest that socioeconomic status (SES), among other factors, may have an impact on cardiovascular health. SES is defined by the educational attainment, employment status as well as income. [...]
