PLACEBO POWER AND IMPACT ON MIND AND BODY

    

A study out of Michigan State University found that nondeceptive placebos, or placebos given with people fully knowing they are placebos, effectively manage stress -- even when the placebos are administered remotely.

Researchers recruited participants experiencing prolonged stress from the COVID-19 pandemic for a two-week randomized controlled trial.

Half of the participants were randomly assigned to a nondeceptive placebo group and the other half to the control group that took no pills.

The participants interacted with a researcher online through four virtual sessions on Zoom.

Those in the nondeceptive placebo group received information on the placebo effect and were sent placebo pills in the mail along with instructions on taking the drugs.

The study, published in Applied Psychology: Health and Well-Being, found that the nondeceptive group showed a significant decrease in stress, anxiety, and depression in just two weeks compared to the no-treatment control group.

Participants also reported that the nondeceptive placebos were easy to use, manageable, and appropriate.

"Exposure to long-term stress can impair a person's ability to manage emotions and cause significant mental health problems long-term, so we're excited to see that an intervention that takes minimal effort can still lead to significant benefits," said Jason Moser, co-author of the study and professor in MSU's Department of Psychology.

"This minimal burden makes nondeceptive placebos an attractive intervention for those with significant stress, anxiety, and depression."

The researchers are particularly hopeful about the ability of healthcare providers to remotely administer the nondeceptive placebos.

"This ability to administer nondeceptive placebos remotely increases scalability potential dramatically," said Darwin Guevarra, co-author of the study and postdoctoral scholar at the University of California, San Francisco, "Remotely administered nondeceptive placebos have the potential to help individuals struggling with mental health concerns who otherwise would not have access to traditional mental health services."

PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY

  PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY Building on prior studies with healthy-weight participants, the new research includes different body sizes.         New research indicates that weight influences how and when bodies burn energy. An Oregon Health & Science University study published in the journal  Obesity  found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who are obese spend more energy during the night when most people sleep. The study also found that during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar. "It was surprising to learn how dramatically the timing of when our bodies burn energy differed in those with obesity," said the study's first author, Andrew McHill, Ph.D., an assistant professor at the OHSU School of Nursing and the Oregon Institute of ...

WHAT CAUSES ITCHING, AND WHAT STOPS IT?

  WHAT CAUSES ITCHING, AND WHAT STOPS IT?         It can be a relief to scratch the occasional itch, but when itch gets out of control, it can become a severe health problem. How does the body know when to stop? Scientists at UC San Francisco are getting close to an answer. In a breakthrough that could transform how doctors treat conditions from eczema to allergies, they have discovered a feedback loop centered on a single immune protein called IL-31 that causes the urge to itch and dials back nearby inflammation. The findings, published on October 13th in  Science Immunology , lay the groundwork for a new generation of drugs that interact more intelligently with the body's innate self-regulating ability. Previous approaches suggested that IL-31 signals itch and promotes skin inflammation. However, the UCSF team discovered that nerve cells, or neurons, that respond to IL-31, triggering a scratch, also prevent immune cells from overreacting and causing more ...

A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY

  A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY         In a study with 22 pairs of identical twins, Stanford Medicine researchers and their colleagues have found that a vegan diet improves cardiovascular health in as little as eight weeks. Although it's well-known that eating less meat improves cardiovascular health, diet studies often need to be enhanced by genetic differences, upbringing, and lifestyle choices. By studying identical twins, however, the researchers were able to control for genetics and limit the other factors, as the twins grew up in the same households and reported similar lifestyles. "Not only did this study provide a groundbreaking way to assert that a vegan diet is healthier than the conventional omnivore diet, but the twins were also a riot to work with," said Christopher Gardner, Ph.D., the Rehnborg Farquhar Professor and a professor of medicine. "They dressed the same, they talked the same, and they had a banter ...
