A new study led by University of Pittsburgh School of Medicine clinical scientists and UPMC neurosurgeons challenges assumptions about early withdrawal of care in patients with severe traumatic brain injury, or TBI. The research, published today in the journal Neurosurgery, suggests that more than 1 in 3 critically ill patients with TBI could have achieved partial independence if their life-sustaining care had not been withdrawn.

Those hoping to lose weight this year might be tempted to try to a diet challenge in the hopes of kick-starting their weight loss. But while we might think these kinds of short-term, restrictive diets will help give our waistlines a nudge, psychology and physiology shows us why this strategy can be so hard to stick to—and why it probably won't result in long-term weight loss.

How can we influence whether we develop Alzheimer's disease later in life? Neurodegeneration researchers at the Institute for Regenerative Medicine are systematically examining the factors that trigger the onset of the disease—and those that shield us against it.

The choices you make in midlife have an outsized impact on your long-term health, Stanford Medicine specialists say.

Therapies that target the utilization of fat by tumors and activate a type of cell death dependent on fat molecules may be a promising avenue to treat cancer, according to new research by UTHealth Houston.

Poor oral health may increase dementia risk through both biological and social pathways, as reported by researchers from Science Tokyo. Drawing on recent epidemiologic research, the team highlights how eating and speaking difficulties might act as overlooked social mechanisms that may amplify risk by contributing to social isolation. Moreover, in a longitudinal study, they also found that poor oral health is a strong predictor of weight loss in older adults.

Helping women to keep their blood pressure at normal levels could reduce their risk of experiencing pregnancy complications, according to a new study led by researchers at the University of Bristol. The research is published in BMC Medicine.

Many low-income Californians prescribed wildly popular weight loss drugs lost their coverage for the medications at the start of the new year.

A research team led by Professor Chen Peng from the College of Chemistry and Molecular Engineering at Peking University has developed a novel cancer immunotherapy strategy that forces tumors to expose themselves to the immune system.

Research has found the shingles vaccine not only prevents the painful, blistering rash in older people, but also protects the brain.
