The research was published recently online ahead of print in the scientific journal Nature Immunology.
Fear of being stigmatized by health care professionals is a barrier for many patients who are members of the LGBT community — it’s one of the most-reported reasons transgender individuals do not go to the doctor. Kale Edmiston and Lauren Mitchell, Ph.D. candidates at Vanderbilt, want to change that. This month the pair, along with a dedicated group of volunteers, will begin serving as advocates for a pilot program called Trans Buddy.

For many years, key national data on the registered nurse (RN) workforce has only been made available yearly, and was often a year out of date when it was released. That has now changed. Quarterly data on trends in employment-related and certain demographic characteristics of RNs is now available at healthworkforcestudies.com.
While many people try to steer clear of arguments with family members during holiday celebrations, two philosophy professors offer a better solution. Scott Aikin and Robert Talisse co-wrote "Why We Argue (and How We Should)."
In the shadow of the two year anniversary of one of the worst mass shootings in American history, at Sandy Hook Elementary School, an extensive new study by two Vanderbilt University researchers challenges common assumptions about gun violence and mental illness that often emerge in the aftermath of mass shootings. When a mass shooting occurs there seems to be a familiar narrative that untreated mental illness is the primary cause for the terrifying act. But a new study published in the American Journal of Public Health by Dr. Jonathan Metzl and Kenneth T. MacLeish finds that an isolated focus on mental illness is misguided.

The research, which appears in the current issue of the journal Cancer, found that the vast majority of survivors work full time, live independently and fulfill other milestones of adult life.
Although hummingbirds are much larger and stir up the air more violently as they move, the way that they fly is more closely related to flying insects than it is to other birds.
The recent explosion of social media in our lives and domination of the air waves by so many "experts" are among the reasons people don't feel free to live their lives as they wish, according to Philosophy Professor John Lachs.

The results appear in the November 20 edition of The New England Journal of Medicine.
Far more breast cancer patients are choosing to undergo mastectomy, including removal of both breasts, instead of choosing breast conservation surgery even when they have early stage disease that is confined to one breast, a Vanderbilt study shows. In the past decade, there have also been marked trends toward higher proportions of women opting for breast reconstruction.
