Inside the government study trying to understand the health effects of ultraprocessed foods (external link)

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.

NIH study finds extreme obesity may shorten life expectancy up to 14 years (external link)

Adults with extreme obesity have increased risks of dying at a young age from cancer and many other causes including heart disease, stroke, diabetes, and kidney and liver diseases, according to results of an analysis of data pooled from 20 large studies of people from three countries. The study, led by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health, found that people with class III (or extreme) obesity had a dramatic reduction in life expectancy compared with people of normal weight. The findings appeared July 8, 2014, in PLOS Medicine.

Acute kidney injury, chronic kidney disease each a risk of the other (external link)

NIH study suggests people with either should be monitored for both

Acute kidney injury (AKI) and chronic kidney disease (CKD) are closely intertwined, with each disease a risk factor for developing the other and sharing other risk factors in common, as well as sharing causes for the diseases to get worse, and outcomes, suggests a comprehensive analysis by scientists at the National Institutes of Health and George Washington University Medical Center, Washington, D.C.

NIH study reveals gene critical to the early development of cilia (external link)

Cilia are key to a broad class of genetic disorders

Researchers at the National Eye Institute (NEI) have described the functions of a gene responsible for anchoring cilia – sensory hair-like extensions present on almost every cell of the body. They show in a mouse model that without the gene Cc2d2a, cilia throughout the body failed to grow, and the mice died during the embryonic stage. The finding adds to an expanding body of knowledge about ciliopathies, a class of genetic disorders that result from defects in the structure or function of cilia. NEI is part of the National Institutes of Health.

Adults stop anti-rejection drugs after partial stem-cell transplant reverses sickle cell disease (external link)

NIH trial success suggests a new treatment option for older, sicker patients

Half of patients in a trial have safely stopped immunosuppressant medication following a modified blood stem-cell transplant for severe sickle cell disease, according to a study in the July 1 issue of the Journal of the American Medical Association. The trial was conducted at the National Institutes of Health’s Clinical Center in Bethesda, Maryland, by researchers from NIH’s National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the National Heart, Lung, and Blood Institute (NHLBI).

NIH scientists take totally tubular journey through brain cells (external link)

Study may advance understanding of how brain cell tubes are modified under normal and disease conditions

In a new study, scientists at the National Institutes of Health took a molecular-level journey into microtubules, the hollow cylinders inside brain cells that act as skeletons and internal highways. They watched how a protein called tubulin acetyltransferase (TAT) labels the inside of microtubules. The results, published in Cell, answer long-standing questions about how TAT tagging works and offer clues as to why it is important for brain health.

Hormone treatment restores bone density for young women with menopause-like condition (external link)

NIH study reveals way to improve bone health for young women with POI

Researchers have found that hormone replacement therapy in young women with primary ovarian insufficiency (POI) led to increases in their bone mineral density, restoring levels to normal. The study was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health.

NIH embraces bold, 12-year scientific vision for BRAIN Initiative (external link)

New report outlines initiative goals, budget, and timeline

A federal report calls for $4.5 billion in funding for brain research over the next 12 years. The long-term scientific vision of the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative was presented today to National Institutes of Health Director Francis S. Collins, M.D., Ph.D., by his Advisory Committee to the Director (ACD). Dr. Collins accepted the recommendations, calling the report bold and game changing.
