Weighing risks and benefits of drug treatment for major depression
Depression is a common and serious problem for older adults. Some 15 to 20 percent of people aged 65 and older who live independently deal with symptoms of major depressive disorder. For residents of nursing homes, the rates of depression may be as high as 50 percent. For some people, medication is an effective part of treatment for depression.

Prescription drug costs steadily soar, yet price transparency is lacking
After reviewing tens of millions of insurance claims for the country’s 49 most popular brand-name prescription drugs, a team from Scripps Research Translational Institute found that net prices rose by a median of 76 percent from January 2012 through December 2017 - with most products going up once or twice per year. The substantial price increases were not limited to drugs that recently entered the marketplace, as one might expect, or to those lacking generic equivalents.

Cholesterol in eggs tied to cardiac disease, death
Research that tracked the diets, health and lifestyle habits of nearly 30,000 adults across the country for as long as 31 years has found that cholesterol in eggs, when consumed in large quantities, is associated with ill health effects, according to Katherine Tucker, a biomedical and nutritional sciences professor in UMass Lowell's Zuckerberg College of Health Sciences, who co-authored the analysis. The study was published in the Journal of the American Medical Association.

Cancer cells are quick-change artists adapting to their environment
Until now, researchers have assumed that the growth of solid tumors originates from cancer stem cells characterized by specific surface markers, which develop in a fixed, hierarchical order. Accordingly, such cancer stem cells are responsible for tumor progression and produce specific types of more differentiated cancer cells whose fates are predetermined.

Aspirin green light for brain bleed stroke patients, study finds

Researchers say the findings are reassuring for the thousands of people who take the medicines to reduce their risk of heart attack and another common type of stroke caused by blood clots in the brain.

Researchers block protein that plays a key role in Alzheimer's disease
In recent years, it has become increasingly clear to researchers that the protein galectin-3 is involved in inflammatory diseases in the brain. A study led by researchers at Lund University in Sweden now shows the de facto key role played by the protein in Alzheimer's disease. When the researchers shut off the gene that produces this protein in mice, the amount of Alzheimer's plaque and the inflammatory load both decreased.
