Frequent Colds May Affect Brain Aging

Medical advice for individuals with mild-to-moderate infections generally involves getting adequate rest and increasing fluid intake. Interestingly, a recent study published in the journal Brain, Behavior, and Immunity suggests that repeated inflammation caused by the administration of a bacterial toxin to middle-aged mice led to cognitive deficits.  These cognitive deficits were also accompanied by changes […]

Lithium in Drinking Water Linked to Autism Risk

Recent research, spearheaded by a UCLA Health investigator, reveals that expectant mothers whose homes had higher concentrations of lithium in their tap water were at a slightly elevated risk of their children being diagnosed with autism spectrum disorder. The study, published in JAMA Pediatrics, suggests that naturally occurring lithium in drinking water could be a […]

Opioid Prescribing and Suicide Risk

New research study estimates associations of regional change in opioid prescribing with total suicide deaths and suicide overdose deaths involving opioids. The study, published this week in the American Journal of Psychiatry, comes as opioid-related overdoses have reached record highs. The author of the study, and professor of psychiatry and epidemiology at Columbia University, Dr. […]

High Blood Pressure in your 30s is Associated with Worse Brain Health in your 70s

Having high blood pressure in your 30s is associated with worse brain health around age 75, especially for men, according to a new UC Davis study. The research, published this week in JAMA Network Open, compared magnetic resonance imaging (MRI) brain scans of older adults who had high blood pressure between the ages of 30 […]

Colder Temperatures May Help Clear Alzheimer’s-Linked Misfolded Proteins

Lower temperatures have been known to increase longevity for over half a century, but the mechanisms underpinning this increased longevity have remained unclear. Now, scientists have unraveled a mechanism that underpins increased longevity in worms, and shown it to have an effect on human cells. Published in Nature Aging, a study by researchers based in […]

Fasting Diet Reduces Risk Markers Of Type 2 Diabetes

A fasting diet which focuses on eating early in the day could be the key to reducing the risk of developing type 2 diabetes. Researchers from the University of Adelaide and South Australian Health and Medical Research Institute (SAHMRI) compared two different diets: a time restricted, intermittent fasting diet and a reduced calorie diet to […]

Melanoma: Probiotic Bacterium May Influence Immunotherapy Response

Currently, immunotherapy does not work for everyone. In some patients, tumors shrink or even disappear, while other people do not respond to immunotherapy. Scientists are trying to figure out why different people have different responses to this form of cancer treatment. One factor that may be responsible for the varying immunotherapy responsiveness is the gut […]

Umbilical Blood Stem Cell Transplant Puts Woman in HIV Remission

A transplant of stem cells from the umbilical cord has resulted in a mixed-race woman going into remission for HIV for the first time.  The woman, known as the New York patient, has been clear of detectable HIV since 2017, after she received stem cells that had been harvested from umbilical cord blood to treat […]

Promising Immunotherapy for Prostate Cancers

A new drug, a monoclonal antibody known as enoblituzumab, is safe in men with aggressive prostate cancer and may induce clinical activity against cancer throughout the body, according to a phase 2 study led by investigators at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy.  If confirmed in additional studies, […]

Stem Cells May Help Identify New Schizophrenia Drugs

In a study, published in Stem Cell Reports, researchers highlight how various genetic differences have previously been associated with a higher risk of schizophrenia. These differences affect a protein called complement component 4 (C4), which is more active in the brains of people with schizophrenia. To develop effective drugs for lowering C4 levels, the researchers […]
