Trigger warnings do little to reduce people’s distress, research shows

Trigger warnings that alert people to potentially sensitive content are increasingly popular, especially on college campuses, but research suggests that they have minimal impact on how people actually respond to content. The findings are published in Clinical Psychological Science, a journal of the Association for Psychological Science. “We, like many others, were hearing new stories week upon week about trigger […]

Study finds test of protein levels in the eye a potential predictor of (future) Alzheimer’s disease

Low levels of amyloid-β and tau proteins, biomarkers of Alzheimer’s disease (AD), in eye fluid were significantly associated with low cognitive scores, according to a new study published in the Journal of Alzheimer’s Disease. Led by researchers at Boston Medical Center, the study is the first to connect these known AD protein biomarkers in the eye to mental status. These […]

Case study: Bartonella and sudden-onset adolescent schizophrenia

In a new case study, researchers at North Carolina State University describe an adolescent human patient diagnosed with rapid onset schizophrenia who was found instead to have a Bartonella henselae infection. This study adds to the growing body of evidence that Bartonella infection can mimic a host of chronic illnesses, including mental illness, and could open up new avenues of […]

A new model for heart valve disease drug discovery

An article published in Experimental Biology and Medicine describes a new model for heart valve physiology. The study, led by Dr. Carla Lacerda, from the Department of Chemical Engineering at Texas Tech University reports that 10% cyclic radial strain on isolated mitral valve anterior leaflets provides a true physiological environment that can be used for mechanistic studies and drug discovery.

Diabetics more likely to experience high blood sugar after joint surgery

People with diabetes who undergo joint replacement surgery are at sharply higher risk of experiencing elevated blood sugar after the operation, increasing their chances of developing infections and other complications, according to a new study by researchers at Hospital for Special Surgery (HSS) in New York City and The Ochsner Health System in New Orleans. Previous studies have shown that […]

A new battle: Veterans more likely to have heart disease

After the war is over, veterans face a new threat. They are more likely to have heart disease at a younger age than nonveterans, and this could herald a new health crisis on the horizon. These results are published in a new University of Central Florida study appearing in the Journal of the American Board of Family Medicine. “I think […]

Taking the reins on multiple sclerosis

Multiple sclerosis doesn’t have to be an ending. With proper treatment and management, patients can manage the disease’s often unpredictable nature. “Patients get a predisposed feeling that their life is doomed. That it’s going to be a complicated life, which isn’t necessarily so,” said Dr. Cary Twyman, a neurologist with Penn State Health. “There are many misconceptions and false information […]

Antimicrobial film could revolutionize common dental procedures

Three million people in the United States currently have dental implants, and every year that number increases by about 500,000. But, for some, getting a dental implant is not the end of the story. Similar to what occurs with a natural tooth, bacteria can build up on the implant’s base and below the gum line. Over time, the bacteria can […]

Drug delivery system would allow tuberculosis patients to switch from daily to monthly doses

Tuberculosis is one of the world’s deadliest infectious diseases: One-third of the world’s population is infected with TB, and more than 1 million people die from the disease every year. One reason TB is so pervasive is that treatment requires a six-month course of daily antibiotics, which is difficult for about half of all patients to adhere to, especially in […]

Researchers discover serotonin can regulate gene expression inside neurons

The brain chemical serotonin, a neurotransmitter long known for its role in passing signals between neurons in the brain, can also regulate expression of genes within neurons in an unexpected way, according to research conducted by neuroscientists at the Icahn School of Medicine at Mount Sinai and published on March 13 in the journal Nature. The discovery may help scientists […]
