The Food and Drug Administration has approved the first vaccine for dengue, Dengvaxia, but placed significant restrictions on its use because the vaccine has been shown to put some people at heightened risk for a severe form of the disease.

Scientists have long known what causes sickle-cell disease and its devastating effects: a single mutation in one errant gene. But for decades, there has been only modest progress against an inherited condition that mainly afflicts people of African descent.

With advances in gene therapy, that is quickly changing — so much so that scientists have begun to talk of a cure.

For the past two decades, scientists have been exploring the genetics of schizophrenia, autism and other brain disorders, looking for a path toward causation. If the biological roots of such ailments could be identified, treatments might follow, or at least tests that could reveal a person’s risk level.

If you are divorced, widowed or never married and develop cancer, watch out. You may get less aggressive treatment than your married friends.

We’ve often heard about studies showing that married adults are more likely to survive cancer than singles. But buried in those same studies is another finding that hasn’t made the headlines. When surgery or radiotherapy is the treatment of choice, patients with spouses are more likely to get it.

The children granted wishes were substantially less likely to visit the emergency department or to have an unplanned hospital admission within two years as compared with children who hadn’t received wishes. (Researchers matched the children’s personal and disease characteristics in the study.)

“My hypothesis is that these kids, when they come back, are more engaged with their families and medical providers, and perhaps they’re more adherent to their treatment plan,” says the study’s lead author Dr. Anup D. Patel, section chief of neurology at Nationwide Children’s Hospital and an associate professor of pediatrics at Ohio State University College of Medicine in Columbus.

The Food and Drug Administration on Friday approved a new form of an extremely potent opioid to manage acute pain in adults, weeks after the chairman of the advisory committee that reviewed it asked the agency to reject it on grounds that it would likely be abused.

Effective treatments, combined with a new vaccine, may revolutionize efforts to turn back Ebola, one of the world’s deadliest plagues. The vaccine itself protects health care workers tending to patients, as well as family members and others who have been in contact with them and may be infected.

“We were both aware that in the LGBTQ world, there’s a fair amount of ageism and lack of awareness about aging, and in the aging world there’s a fair amount of homophobia and transphobia and lack of awareness of LGBTQ issues, especially trans identities.”

The discussion of race and medicine in the United States is challenging and emotionally charged. Substantial disparities in health outcomes, based on race, ethnicity, and socioeconomic status, continue to exist; additional reports of racial bias and profound insensitivity in research continue to emerge in the popular media. A renewed discussion of race as a biological vs social construct has begun and is complicated by emerging data on genetics, race, and ancestry.
