Large US trial supports silver diamine fluoride for severe early childhood caries

A phase 3 randomized trial of 830 young children with severe early childhood caries found that 38% silver diamine fluoride arrested 54.0% of eligible cavitated dentin lesions at six months, compared with 22.5% after placebo. The noninvasive treatment showed clinically meaningful efficacy, but about half of the lesions remained active, supporting close monitoring and additional preventive care.

Advances in X chromosome inactivation open therapeutic opportunities for X-linked genetic disorders

A new review explores how advances in understanding X chromosome inactivation (XCI) are creating potential therapeutic opportunities for a range of X-linked genetic disorders, including Rett syndrome, Fabry disease, Duchenne muscular dystrophy, hemophilia, and others.

Texas A&M study links polyethylene microplastics to fatty liver disease

Microplastics have become nearly impossible to avoid. They have been detected in oceans, drinking water and even the human body, but scientists are still uncovering how they affect human health.

Study links ancient evolutionary pressures to severe COVID-19 risk

Every time a virus invades a person, it collides with thousands of years of human history. A study led by researchers at the USC Dornsife College of Letters, Arts and Sciences and Howard University suggests that some of the genes involved in the body's immune response today bear the marks of ancient battles with infectious diseases.

Newly-discovered protein acts as off switch for human immune cells

Mayo Clinic researchers have identified a protein that cancer cells use to shut down the body's immune response, a discovery that could help scientists develop new treatments that make cancer immunotherapies more effective.

Sensitive parenting buffers against child ADHD risks from pregnancy

Research from Oregon Health & Science University's Center for Mental Health Innovation provides new evidence that the way caregivers interact with children when they're very young can protect against the negative effects of inflammation during pregnancy, including increased attention-deficit/hyperactivity disorder, or ADHD, symptoms in children.

Five large corporations dominate Medicaid mental health care for adolescents

The United States is in the middle of a well-documented adolescent mental health crisis. Because Medicaid provides medical coverage for roughly half of all children in the country, the program has an essential role in responding to that crisis.

Using DNA sequencing for accurate identification of microbial infections in cystic fibrosis patients

Lung infections are a constant risk for people living with cystic fibrosis (CF), a life-threatening genetic disorder which impairs lung function, predisposes people to persistent airway infections and exposes them to acquiring multidrug resistant infections.
