Updated Guidelines Shed Light on Using Radiation Against Brain Metastases

The American Society for Radiation Oncology recently released a new clinical guideline that offers guidance on how radiation therapy should be used when treating brain metastases. Brain metastases are tumors that develop when cancer cells from a primary tumor located in another part of the body — mostly melanoma, breast cancer or lung cancer — spread to a patient’s brain. These tumors develop in about 40% of individuals who have already been diagnosed with cancer, with almost 200,000 new cases being diagnosed annually in America. Radiation therapy is usually used to manage these brain tumors, providing patients relief from dizziness, headaches and…

Researchers Have Found Brain Cells That Die Due to Parkinson’s Disease

Parkinson’s disease is a brain disorder that causes uncontrollable or unintended movements, such as stiffness, shaking and difficulty with coordination and balance. The disorder’s symptoms worsen over time as the disease progresses, with patients finding it difficult to even talk and walk when the disease is in its advanced stages. Estimates show that almost one million individuals in America suffer from Parkinson’s disease. New research has identified the brain cells susceptible to Parkinson’s disease, and this could help scientists have a better understanding of how this debilitating illness takes hold and perhaps identify ways to prevent its progression. Researchers have…

Study Discovers Mechanisms Behind Relapse After Treatment of MDD

A new study has discovered abnormalities in neural emotional regulation in individuals suffering from remitted major depressive disorder (MDD). The study’s findings highlight some neural mechanisms that may play a role in relapse. The author of the study, Rozemarijn S. van Kleef, stated that the interest in this role arose from the fact that depression recurring after remission was a huge issue on a societal as well as a personal level. A psychological therapist, van Kleef explained that it was crucial to gain more insight into the mechanisms underlying this recurrence, giving the examples of prior studies, which had found…

Researchers Develop Models to Better Understand Brain Cancer Metastasis

When cancer cells spread to the brain, they lead to the formation of brain metastases. Metastases are the primary cause of mortality and morbidity linked to cancer. Researchers at Instituto de Medicina Molecular have developed models to study brain metastases, which may help to better understand cancer and find new treatment approaches that can be modified to fit the needs of every patient. For their study, the researchers gathered brain metastases from patients with cancer that arose from tumors located in other organs. They used these cells to generate ailment models that mimicked the illness of every patient. The scientists…

Study Finds Service Dogs Help Individuals with PTSD

Post-traumatic stress disorder is a mental health disorder brought on by experiencing or witnessing a traumatic or terrifying event. This condition may last a few months or even years, with triggers unearthing traumatic memories and causing intense physical and emotional reactions. To help manage the condition’s symptoms, patients are sometimes assigned a buddy dog to be their companion during their daily activities. For a long time, patients with post-traumatic stress disorder have argued that a buddy dog helped better their lives. However the lack of scientific evidence made it hard to substantiate these claims — until now. A new study…

U.S. Army Sued Over Discharging Soldiers with Substance-Abuse Issues

The U.S. Army is being sued for violating the Constitution as well as its own regulations and veterans’ rights by failing to give soldiers with drug and alcohol use disorders honorable discharges, which would have qualified them for federal benefits. Army Secretary Christine Wormuth is being sued by Mark Stevenson, an army veteran, in federal court. Stevenson seeks to compel the military to upgrade his discharge status as well as those of other veterans who weren’t honorably discharged due to misconduct associated with their substance abuse disorders. Stevenson enlisted in the U.S. Army in 1977, revealing that he developed problems…

Study Finds Strong Link Between Hormone Drug, Growth of Brain Tumors

A new study has found that a drug that is commonly used to hormonally treat conditions such as prostate cancer, early puberty and excessive hair growth may be linked to a heightened risk of meningioma. The study was carried out by researchers at the University of Bristol who collaborated with researchers at the National University of Singapore and the University of Cambridge. The findings were published in “Scientific Reports.” Meningioma is a common type of brain tumor that is typically benign and slow growing. These tumors are known to trigger disability by squeezing or compressing the adjacent vessels and nerves…

New Study Sheds Light on Inflammation Linked to COVID-19

A new study has provided new insights into why the SARS-CoV-2 virus, which is known to cause COVID-19, can sometimes fuels inflammation, which in turn causes serious illness. This research was led by scientists at Boston Children’s Hospital and Harvard Medical School. Its findings were published in the “Nature” journal. The researchers also discovered that the SARS-CoV-2 virus infects and kills specific cells in the immune system in the lungs and the blood. The elimination of these alarms is what triggers the immune system. In a news release, Professor Judith Lieberman, one of the leaders of the study, stated that…

Johns Hopkins Researchers Receive Millions for New Cancer Research Projects

The Departments of Pathology, Neurosurgery and Gynecology/Obstetrics and the Kimmel Cancer Center at Johns Hopkins have received almost $8 million for new research projects to discover cures for a number of fatal cancers, including ovarian cancer, pancreatic cancer and glioblastoma. The projects are being financed by Break Through Cancer, a cancer research foundation, as part of an effort for researchers across a quintet of cancer research centers. The other cancer research centers include the University of Texas MD Anderson Cancer Center in Houston; Koch Institute for Integrative Cancer Research at MIT, Cambridge, Massachusetts; the Memorial Sloan Kettering Cancer Center in…

Researchers May Have Found New Way to Slow Progression of Cancer

Scientists at the University of Sussex may have discovered a way to decrease the speed at which glioblastoma grows and strengthen potential treatments for the brain tumor. Glioblastoma is a common tumor found in adults. This aggressive tumor is often resistant to treatment, making it fatal. In their new study, researchers have shown that differentiation therapy may be used to limit the growth of the tumors and turn off the malignant properties of cancerous cells. They suggest that an inhibitor drug known to target certain cell proteins may be used to make glioblastoma treatments more effective. Professor Georgios Giamas of…
