Researchers Develop Blood Test to Improve Tumor Diagnosis, Monitoring

Scientists at Massachusetts General Hospital have developed a tool that can detect additional mutations to help improve tumor diagnosis and monitoring. The scientists, who have in the past created a blood test to detect mutations in a glioma-linked gene, published their findings in “Clinical Cancer Research.” Gliomas are a common type of brain tumors that occur in adults. This advancement offers clinicians a strong tool to help uncover the presence of gliomas through the detection of mRNA in a patient’s blood. mRNA are pieces of the genetic material of tumor cells. Prior research was the first to highlight that this…

Research Suggests How Individuals Can Control Unwanted Thoughts

Intrusive or unwanted thoughts are a common human experience. They often appear out of the blue, and in most cases, they tend to be unpleasant and unwanted. Unwanted thoughts and images can cause distress, especially when they force you to think about past traumatic or distressing events. Sometimes these thoughts can be associated with psychiatric disorders, including anxiety, depression and obsessive-compulsive disorder. Nevertheless, intrusive thoughts are a normal part of life despite the distress they can cause, and it is possible for you to control them. According to a study by the Hebrew University of Jerusalem, most people employ a…

Study Highlights Concerns on Police Involvement in Emergency Mental Health Transfers

The police don’t have a good reputation when it comes to dealing with individuals with mental health crises. Police encounters have repeatedly proven to be particularly dangerous for people with mental illness, with these encounters often ending in injury and failing to provide the involved individuals the mental help they need. Even so, a recent study has revealed that university health centers in the Ontario region still rely on law enforcement for emergency mental-health transfers. The study, whose findings were reported in the “Canadian Medical Association Journal,” shows that health practitioners often prefer to call the police, even though they…

Researchers Have Found a New, Fatal Pediatric Subtype of Cancer

Liver cancer is quite rare in children and teens, accounting for only 1% to 2% of pediatric cancers. Even so, it affects around two to three million minors, usually in the first three years of their lives. For the past couple of decades, experts have classified pediatric liver cancers as either hepatocellular or hepatoblastoma carcinomas, with statistics showing that the survival rate for hepatoblastoma after five years is 75% to 80%. Pediatric pathologists have now revealed that there are certain liver cancers whose characteristics do not meet the criteria of the two established carcinoma models. These liver tumors are more…

Loss of Y Chromosomes in Older Men Elevates Heart Disease Risk, Study Finds

A new study has found that older men losing the Y chromosome in their white blood cells as they age can heighten their risk of death from cardiovascular illnesses and cause severe heart problems. This genetic change, which is scientifically referred to as mosaic Loss of y or mLOY, impacts about 20% of men aged 60 and 40% of those aged 70 and above. The study was carried out by researchers at Sweden’s Uppsala University and the University of Virginia. It was led by Professor Kenneth Walsh of the School of Medicine at the University of Virginia and Associate Professor…

Study Reveals Proteins That Can Trigger Immune System Malfunction

At least 20 million Americans live with autoimmune disorders, but there’s still much we don’t know about these conditions. The disorders usually occur when, for some reason, the immune system goes haywire and begins to attack healthy tissue. In addition to not knowing exactly what causes autoimmune disorders, we still haven’t figured out a way to cure them. Recently, however, researchers studying immune disorders discovered a novel method of triggering the immune system via certain proteins. This discovery could provide scientists with the chance to know more about autoimmune conditions such as lupus and scleroderma. Investigators from Weill Cornell Medicine…

Study Highlights New Insights on Neurological Autoimmune Illnesses

UT Southwestern researchers recently reported that they had used cryoelectron microscopy to obtain the image of an auto-antibody that had bound itself to the surface receptor of a nerve cell. This discovery shows the mechanism behind neurological autoimmune illnesses and may be useful in the development of novel therapies for autoimmune diseases. Autoimmune illnesses are disorders that cause an individual’s immune system to mistakenly attack their body. These illnesses reduce the body’s ability to fight germs such as viruses and bacteria, which in turn, makes individuals susceptible to infections. Common autoimmune illnesses include systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis,…

Preclinical Study Uncovers Potential Key to Treating Deadly Brain Tumors

A new study has found an alternative approach that would make immunotherapy treatments more effective when treating brain tumors. Immunotherapy drugs are usually used to treat a range of cancers. However, glioblastoma multiforme, which is a fatal type of cancer, remains resistant to this revolutionary treatment because the immune system finds it hard to detect and target these tumors, allowing them to grow undisturbed. Researchers have been looking for ways to treat this deadly cancer whose tumors are usually hidden behind the blood-brain barrier. This location hinders drugs from crossing into the central nervous system’s fluid. For their research, the…

Scientists Identify Gene Behind Pediatric Bone Cancer

Scientists at the Lineberger Comprehensive Cancer Center, University of North Carolina have found that the OTUD7A gene impacts Ewing sarcoma development. Ewing sarcoma is a type of cancer that develops primarily in children and affects bones or tissues surrounding the bones. Figures show that roughly 250 young adults and children are diagnosed with this rare cancer annually in the United States. Of this number, about one-half eventually succumb to the illness, which points to the need for better treatments. The researchers, who collaborated with Atomwise Inc. on this study, published their findings in the “Advanced Science” journal. Pengda Liu, co-lead…

Study Maps How Brain Changes During Treatment for Depression

New research has mapped how an individual’s brain changes as they undergo treatment for depression. The study, which was carried out by scientists from the University of British Columbia, was focused on finding out what happened in the brain when a person underwent repetitive transcranial magnetic stimulation. This noninvasive treatment uses magnetic fields to stimulate nerve cells in an individual’s dorso-lateral prefrontal cortex. This region of the brain is involved in mood regulation. This particular treatment is usually administered when other treatment strategies, such as drugs, haven’t effectively helped a patient manage their depression. Various studies have found that antidepressants…
