Stress and sex influence traumatic brain injury outcomes, rat study suggests

How stress impacts behavioral outcomes of traumatic brain injury (TBI) represents a major gap in knowledge. This oversight is especially felt by those in the military due to the high prevalence of TBI and the abundance of stress that they endure. Researchers led by Pamela VandeVord at Virginia Tech discovered that prior stress exposure influences TBI outcomes in a sex-dependent manner.

Synthetic mRNA therapy: Study introduces weapon against metastatic cancer without harmful side effects

Cancer metastasis, the spread of cancer to organs, is a major cause of cancer-related deaths. Once cancer spreads to multiple organs, conventional treatments like surgery, radiation, and chemotherapy become less effective. Scientists at Shinshu University School of Medicine have developed a synthetic mRNA that, when injected, revitalizes the immune system to recognize and attack metastasizing cancer cells. This breakthrough could lead to new therapies to improve survival rates for cancer patients.

Tools to succeed: Learning support for new nurses

First-year nurses often have difficulties while bridging the gap between educational theory and required workplace practice. In the fast-paced medical field, sufficient guidance is hard to come by, so new nurses must actively learn on their feet through modeling senior nurses’ actions and techniques. There are several studies on learning from role models, but no specific tools that focus on new nurses’ learning progress through this practice.

Regular exercise pre-hospitalization is linked to better outcomes in heart failure, study shows

Heart failure is a major health concern, especially for aging populations—it significantly increases mortality rates, and severely impacts quality of life of those affected. Exercise therapy has been shown to be particularly effective for patients with heart failure. Previous research, however, has mainly examined the benefits of exercise after a diagnosis of heart failure.
