Inside the government study trying to understand the health effects of ultraprocessed foods

BETHESDA, Md. (AP) — Sam Srisatta, a 20-year-old Florida college student, spent a month living inside a government hospital here last fall, playing video games and allowing scientists to document every morsel of food that went into his mouth.

From big bowls of salad to platters of meatballs and spaghetti sauce, Srisatta noshed his way through a nutrition study aimed at understanding the health effects of ultraprocessed foods, the controversial fare that now accounts for more than 70% of the U.S. food supply. He allowed The Associated Press to tag along for a day.

“Today my lunch was chicken nuggets, some chips, some ketchup,” said Srisatta, one of three dozen participants paid $5,000 each to devote 28 days of their lives to science. “It was pretty fulfilling.”

Examining exactly what made those nuggets so satisfying is the goal of the widely anticipated research led by National Institutes of Health nutrition researcher Kevin Hall.

“What we hope to do is figure out what those mechanisms are so that we can better understand that process,” Hall said.

Raising the curtain on cerebral malaria’s deadly agents

NIH scientists film inside mouse brains to uncover biology behind the disease.

Using state-of-the-art brain imaging technology, scientists at the National Institutes of Health filmed what happens in the brains of mice that developed cerebral malaria (CM). The results, published in PLOS Pathogens, reveal the processes that lead to fatal outcomes of the disease and suggest an antibody therapy that may treat it.

No safe level of smoking: Even low-intensity smokers are at increased risk of earlier death

People who consistently smoked an average of less than one cigarette per day over their lifetime had a 64 percent higher risk of earlier death than never smokers, and those who smoked between one and 10 cigarettes a day had an 87 percent higher risk of earlier death than never smokers, according to a new study from researchers at the National Cancer Institute (NCI). Risks were lower among former low-intensity smokers compared to those who were still smokers, and risk fell with earlier age at quitting. The results of the study were reported Dec. 5, 2016, in JAMA Internal Medicine. NCI is part of the National Institutes of Health.

Research on new, rapid screening test identifies potential therapies against drug-resistant bacteria

Researchers at the National Institutes of Health’s National Center for Advancing Translational Sciences (NCATS), Clinical Center and National Institute of Allergy and Infectious Diseases (NIAID) have created a new way to identify drugs and drug combinations that may potentially be useful in combating infections that are resistant to many different antibiotics. They developed an assay (test) to rapidly screen thousands of drugs to determine how effective they were against a variety of types of resistant bacteria.

Testing of investigational inactivated Zika vaccine in humans begins

First of five planned clinical trials to test ZPIV vaccine.

The first of five early stage clinical trials to test the safety and ability of an investigational Zika vaccine candidate called the Zika Purified Inactivated Virus (ZPIV) vaccine to generate an immune system response has begun at the Walter Reed Army Institute of Research (WRAIR) Clinical Trial Center in Silver Spring, Maryland. Scientists with WRAIR, part of the U.S. Department of Defense (DoD), developed the vaccine. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), is co-funding the Phase 1 clinical trial with WRAIR, serving as the regulatory sponsor and providing other support.

New method for performing aortic valve replacement proves successful in high-risk patients

Researchers at the National Institutes of Health have developed a new, less invasive way to perform transcatheter aortic valve replacement (TAVR), a procedure widely used to treat aortic valve stenosis, a lethal heart condition. The new approach, called transcaval access, will make TAVR more available to high risk patients, especially women, whose femoral arteries are too small or diseased to withstand the standard procedure.

NIH researchers unveil new wound-healing role for protein-folding gene in mice

National Institutes of Health researchers have identified a novel role for a gene known as heat shock protein 60 (Hsp60), finding that it is critical in tissue regeneration and wound healing. The study found that topical treatment of an Hsp60-containing gel dramatically accelerates wound closure in a diabetic mouse model.

Scientists propose neuroscience framework for diagnosing addictions

Scientists at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health, propose using an assessment tool to diagnose addictive disorders that considers addiction-related behaviors, brain imaging, and genetic data. According to a new review article, the Addictions Neuroclinical Assessment (ANA) would facilitate future understanding of the origin of addiction at a biological level, and could ultimately lead to more effective individualized treatments for addictions. The review appears online in the journal Biological Psychiatry.

Gene therapy shows promise for treating Niemann-Pick disease type C1

NIH mouse study could lead to human clinical trials.

For the first time, National Institutes of Health researchers have demonstrated in mice that gene therapy may be the best method for correcting the single faulty gene that causes Niemann-Pick disease, type C1 (NPC1). The gene therapy involved inserting a functional copy of the NPC1 gene into mice with the disease; the treated animals were then found to have less severe NPC1 symptoms.

This detailed drawing of cells visualizes how the gene therapy involved inserting a functional copy of the NPC1 gene into mice with the disease.

NIH study determines key differences between allergic and non-allergic dust mite proteins

Finding may lead to better therapies for individuals with dust mite allergies.

Scientists from the National Institutes of Health have determined what differentiates dust mite allergens from the non-allergen proteins dust mites produce. According to the researchers, dust mite allergens are more chemically stable and produced in larger quantities than other dust mite proteins.

NIH scientists uncover genetic explanation for frustrating syndrome

Previously unexplained symptoms found associated with multiple copies of a single gene.

Scientists at the National Institutes of Health have identified a genetic explanation for a syndrome characterized by multiple frustrating and difficult-to-treat symptoms, including dizziness and lightheadedness, skin flushing and itching, gastrointestinal complaints, chronic pain, and bone and joint problems. Some people who experience these diverse symptoms have elevated levels of tryptase — a protein in the blood often associated with allergic reactions. Multiple copies of the alpha tryptase gene drive these tryptase elevations and may contribute to the symptoms, according to a new study led by investigators at NIH’s National Institute of Allergy and Infectious Diseases (NIAID).
