Collaborative research co-led by Dr. Julie St-Pierre’s lab at the University of Ottawa sheds new light on the mysteries of mitochondrial dynamics and its likely role in the metastatic progression of breast cancer – the most commonly-diagnosed cancer in women across the globe. Shapeshifting mitochondria continually fuse and divide, but precisely how those dynamics influence metastatic progression has intrigued scientists. In the work published in Science Advances, the uOttawa-led team puts forth compelling evidence that promoting mitochondrial elongation in cancer cells hobbles their ability to metastasize.

One of the top worries about telehealth is that it will drive up the use of tests and scans that patients don’t need, wasting money and resources. In fact, a new study shows, low-value care didn’t rise faster at primary care practices that used telehealth the most.

In a study published November 7 in the journal Cell Reports Medicine, researchers from Tufts University School of Medicine and Vanderbilt University School of Medicine show that people with schizophrenia generate distinct neural patterns when asked to make decisions based on conflicting information. The work offers one of the first biological tests to assess whether someone is prone to inflexible thinking and, by monitoring changes in these patterns, a new way to measure whether treatments are working. 

A new therapy may delay Alzheimer’s disease progression by years, according to a study by researchers at Texas A&M University College of Medicine.

Research analysing European survey data from 113,884 men who have sex with men (MSM) and published in Eurosurveillance indicates that while most MSM have a basic understanding of viral hepatitis, only 44% report having been vaccinated against both hepatitis A and B.
