Combining data from electronic health records with results from standardized depression questionnaires better predicts suicide risk in the 90 days following either mental health specialty or primary care outpatient visits, reports a team from the Mental Health Research Network, led by Kaiser Permanente research scientists.
Researchers at the Max Planck Florida Institute for Neuroscience in collaboration with researchers at Emory University and the National Institute of Environmental Health Sciences, have for the first time identified a novel role for the CA2-enriched protein RGS14 and provided insights into the mechanism by which it limits plasticity. RGS14 seems to be special, acting as a molecular factor that puts the brakes on plasticity when it's present, enabling specialized types of memory encoding.
A new longitudinal study examined the likelihood of homeless youth of different races being harassed and arrested by police. The study found that nonwhite homeless youth are more likely than white homeless youth to report police harassment and arrest, but that elements of living on the street -- including increased visibility and prior experiences with harassment -- offset racial disparities.
A new study by investigators at Brigham and Women's Hospital explores how HIV establishes a 'persistent reservoir' of infected cells, identifying cellular survival programs that become activated in these cells, and providing a potential target for future therapy.
Exposure to early life trauma can elevate risk for poor physical and mental health in individuals and their children. A new epigenetics study in both men and mice posits that some of the vulnerability in children may derive from stress-associated reductions in microRNAs in their father's sperm.
The blood of schizophrenia patients features genetic material from more types of microorganisms than that of people without the debilitating mental illness.
The study shows racial disparities in suicide rates are age-related. Specifically, suicide rates for black children aged 5-12 were roughly two times higher than those of similarly-aged white children. For older children, the trend reverses back to the national average. For youth aged 13-17 years, suicide was roughly 50 percent lower in black children than in white children.
Caltech researchers gain new insights into the brain mechanisms underlying the negative effects caused by long-term social isolation.
Researchers at the University of Missouri recently found evidence that boosting how well people at risk for psychosis learn from positive and negative feedback could potentially keep psychosis at bay. The team also found that brain scans using functional magnetic resonance imaging, coupled with behavioral measures, could provide markers for the diagnosis of psychosis risk. Researchers hope findings will help mental health professionals to understand how to better treat their patients with psychoses and prevent the onset of psychosis.
Memories can be transferred between organisms by extracting ribonucleic acid (RNA) from a trained animal and injecting it into an untrained animal, as demonstrated in a study of sea snails published in eNeuro. The research provides new clues in the search for the physical basis of memory.
