    What hospitals can do to help keep excess opioids out of communities

    To halt the misuse of opioids, it may help to slash the number of pills prescribed, a new study suggests.

    Five months after the implementation of new opioid prescription guidelines at a University of Michigan hospital, roughly 7,000 fewer pills went home with patients — a drop that might reduce the risk of accessible pills leading to substance abuse. But the opioid reduction didn’t leave...

    Cholera pandemics are fueled by globe-trotting bacterial strains

    Cholera strains behind worldwide outbreaks of the deadly disease over the last five decades are jet-setters rather than homebodies.

    It had been proposed that these cholera epidemics were homegrown, driven by local strains of Vibrio cholerae living in aquatic ecosystems. But DNA fingerprints of the V. cholerae strains behind recent large outbreaks in Africa and Latin America were more...

  • 50 years ago, folate deficiency was linked to birth defects

    Folic acid

    Pregnant women who do not have enough folic acid — a B vitamin — in their bodies can pass the deficiency on to their unborn children. It may lead to retarded growth and congenital malformation, according to Dr. A. Leonard Luhby…. “Folic acid deficiency in pregnant women could well constitute a public health problem of dimensions we have not originally recognized,” he says. — ...

    Scientists are seeking new strategies to fight multiple sclerosis

    James Davis used to be an avid outdoorsman. He surfed, hiked, skateboarded and rock climbed. Today, the 48-year-old from Albuquerque barely gets out of bed. He has the most severe form of multiple sclerosis, known as primary progressive MS, a worsening disease that destroys the central nervous system. Diagnosed in May 2011, Davis relied on a wheelchair within six months. He can no longer get...

    Testosterone may be one reason why men don’t get asthma as much as women

    Testosterone may tamp down asthma caused by inhaling pollen, dust or other airborne allergens. That’s partly why more women suffer from the lung disease than men, new research suggests.

    The male sex hormone acts on a group of immune cells that are part of the first line of the body’s defense against invaders. These cells are thought to kick-start inflammation in the lungs, which causes...

    Step away from the cookie dough. E. coli outbreaks traced to raw flour

    Eggs, long condemned for making raw cookie dough a forbidden pleasure, can stop taking all the blame. There’s another reason to resist the sweet uncooked temptation: flour.

    The seemingly innocuous pantry staple can harbor strains of E. coli bacteria that make people sick. And, while not a particularly common source of foodborne illness, flour has been implicated in two E. coli outbreaks...

    How dad’s stress changes his sperm

    Sperm from stressed-out dads can carry that stress from one generation to another. “But one question that really hasn’t been addressed is, ‘How do dad’s experiences actually change his germ cell?’” Jennifer Chan, a neuroendocrinologist at the University of Pennsylvania, said November 13 in Washington, D.C., at the annual meeting of the Society for Neuroscience.

    Now, from a study in mice...

    New blood pressure guidelines put half of U.S. adults in unhealthy range

    ANAHEIM, Calif.  — Nearly half of U.S. adults now have high blood pressure, thanks to a new definition of what constitutes high: 130/80 is the new 140/90. That means that 103 million people — up  from 72 million under the old definition — need to make diet and exercise changes and, in some cases, take medication to lower their risk of heart attack or stroke.

    These new blood pressure...

    Human study supports theory on why dengue can be worse the next time around

    Et tu, antibody? In humans, dengue can be more severe the second time around. Now, a study implicates an immune system treachery as the culprit.

    The study suggests that the amount of anti-dengue antibodies a person has matters. In a 12-year study of Nicaraguan children, low levels of dengue antibodies left over in the blood from a prior infection increased the risk of getting a life-...

    Gut feelings

    Tests in mice show that microbes in the gut may tamper with the production of tiny molecules in brain regions known to help control anxiety, Maria Temming reported in “How gut bacteria may affect anxiety” (SN: 9/30/17, p. 12).

    Online reader Amanda wondered what has more influence: gut bacteria on anxiety, or anxiety on the bacterial makeup of the gut. If bacteria have more of...
