A woman lies in her hospital bed. Her heart rate is elevated, she has a slight fever and an elevated white blood cell count.

Could this be the beginnings of sepsis, a life-threatening reaction to an infection? Or could these simply be signs of a normal pregnancy?

Maternal sepsis, which occurs during pregnancy or postpartum, is a rare but possibly preventable complication that accounts for 12.7 percent of pregnancy-related deaths in the United States each year.

WASHINGTON -- A comprehensive analysis examining the relationship between vaping and smoking among youth and young adults finds that cigarette smoking dramatically decreased between 2013 and 2017 just as e-cigarette use became more popular.

The study, published in the journal Tobacco Control, looked at five different U.S. population-level surveys that covered the four year time frame -- the time during which vaping became increasingly popular.

ANN ARBOR, Mich. - A significant proportion of suicidal teens treated in a psychiatric emergency department said that watching the Netflix series "13 Reasons Why" had increased their suicide risk, a University of Michigan study finds.

The hit drama, widely popular among teens, has generated controversy for its depiction of suicide. Its story centers around a 17-year-old student, who, before her death, recorded cassettes that detail 13 reasons why she took her own life.

Washington, DC - From online forums to community groups, research and experience shows people are more willing to insult and use menacing language online than in person, especially when there's the protection of anonymity behind a computer. New research appearing in Social Psychological and Personality Science indicates that people react less strongly to malicious speech on digital platforms and see the victims as less "harmed" than if the words were said directly to a person.

Each year 5-10 per cent of all the children born in the world are born prematurely. At this stage, their organs and immune system are not mature, and the children are therefore highly susceptible to serious infections. One of the problems facing a lot of children born prematurely is the immaturity of the gastrointestinal tract, which among other things causes them to be hypersensitive to bacteria. Now a study conducted by researchers of biomedicine at the University of Copenhagen offers new hope.

The brains of teenage girls who engage in serious forms of self-harm, including cutting, show features similar to those seen in adults with borderline personality disorder, a severe and hard-to-treat mental illness, a new study has found.

Some things are so complicated that it is completely impossible to precisely calculate them. This includes large quantum systems, which consist of many particles, particularly when they are not in an equilibrium state, but changing rapidly. Such examples include the wild particle inferno that occurs in particle accelerators when large atoms collide, or in the early universe, just after the Big Bang, when particles rapidly expanded and subsequently cooled.

SAN DIEGO - New research could help explain why stress early in life can create vulnerabilities to mood and anxiety disorders later on.

The study, led by researchers at The Ohio State University, was presented Nov. 5 in San Diego at the annual Society for Neuroscience meeting, and highlights the important role of mast cells.

SAN DIEGO -- Excessive stress during fetal development or early childhood can have long-term consequences for the brain, from increasing the likelihood of brain disorders and affecting an individual's response to stress as an adult to changing the nutrients a mother may pass on to her babies in the womb. The new research suggests novel approaches to combat the effects of such stress, such as inhibiting stress hormone production or "resetting" populations of immune cells in the brain.

CHAMPAIGN, Ill. -- Demographic and cultural differences strongly influence the coping styles young people use when they're affected by a natural disaster, and these disparities should be taken into account when providing services to help them recover from these traumatic experiences, a new study found.

University of Illinois social work professors Tara M. Powell and Kate M. Wegmann led the study, which utilized a new method of assessing coping among disaster-affected youths to address the limitations of a commonly used survey called Kidcope.
