A new study has revealed a group of blood proteins that are altered in people who go on to develop multiple sclerosis (MS), in some cases more than a decade before diagnosis. The findings offer hope that a simple blood test could one day identify people at high risk of MS in time to act before damage occurs.

Many people living with dementia never receive an accurate diagnosis, in part because Alzheimer's disease, Parkinson's disease and related conditions are notoriously difficult to tell apart and often occur together. Now, a new tool based on artificial intelligence and a simple blood draw may provide clarity.

Alzheimer's disease is a neurodegenerative disease characterized by a progressive decline in mental functions and memory loss. Along with frontotemporal dementia and some other neurodegenerative disorders, Alzheimer's disease has been associated with an accumulation inside neurons of abnormal clumps of a protein called "tau."

Researchers have found that consuming lower amounts of protein-rich foods may negatively affect physical functioning as people grow older, underscoring the vital function protein plays in preserving mobility and muscle strength in adulthood. In a large aging cohort study published in the journal Nutrients, the researchers report that regular dietary habits, particularly the consumption of protein-rich foods, can influence how well individuals move and perform daily activities later in life.

A new study by emergency medicine researchers at UC Davis Health set out to assess the effects of naloxone administration by first responders treating patients with out-of-hospital cardiac arrest (OA-OHCA). The study, published in JAMA Network Open, found naloxone administration during resuscitation by emergency medical service (EMS) personnel was associated with improved outcomes in patients with suspected OA-OHCA.

Pediatric patients with obesity undergoing adenotonsillectomy (AT) face longer operating times, according to a study published online May 21 in the Ear, Nose & Throat Journal.

In an editorial published in the New England Journal of Medicine, University of Michigan Health hepatologist Anna S. Lok, M.D., hails newly announced results of the B-Well clinical trials as "a major step toward a functional cure for hepatitis B virus infection."

Using patient-derived cardiac tissue and stem cell-based models, the team of translational researchers demonstrated that targeting the genetic cause of disease improved cellular abnormalities and identified the biological pathways involved. The results of this study were published in Signal Transduction and Targeted Therapy.

An international research team led by Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) in Rovereto (Trento, Italy) and the Child Mind Institute in New York (U.S.), and in collaboration with researchers from the University of Trento, has shown that it is possible to identify at least two distinct subtypes of autism, defined by their patterns of brain connectivity. In the "hyperconnectivity" subtype, brain areas communicate more than usual; in the "hypoconnectivity" subtype, c

An estimated 1 in 8 women live with polycystic ovarian syndrome, commonly referred to as PCOS. However, the name is a bit of a misnomer; it suggests that the condition affects only the ovaries. In actuality, the condition is a broader metabolic and hormonal disorder. After years of research and patient advocacy, a recent report in The Lancet announced a new designation to reflect the condition's whole-body impact: polyendocrine metabolic ovarian syndrome (PMOS).

Dr. James Mu had braced for the call that came in late January. A patient from his rural Northern California county had measles, a disease so rare there that many physicians have never treated a case.

Being admitted to a mental health unit can be one of the most vulnerable moments in a person's life. They often arrive in the midst of a crisis, and are fearful, confused, and anxious. But in these situations, one thing can profoundly affect their experience: the relationship established with the nurses who attend them, especially in the first days.

A new study from researchers at the Child Mind Institute finds that negative online experiences are common among children and adolescents with mental health and neurodevelopmental conditions, and that most incidents are not reported through platform reporting tools.

Having a preexisting autoimmune disease is an independent risk factor for poor outcomes with myelodysplastic syndrome (MDS), according to a study published in the June issue of Clinical Immunology.
