Weight loss surgery in teen years may improve diabetes, blood pressure outcomes

Weight loss surgery in teen years may improve diabetes, blood pressure outcomes

Health
May 16 (UPI) -- Gastric bypass surgery is producing good, sustained health outcomes for adults, but in some ways isn't working as well for teens, a new study says. After having weight loss surgery, a group of teens with obesity lost 26 percent of their body weight, while the adults with obesity lost 29 percent of their weight, according to a study published in The New England Journal of Medicine. The study was also funded by the National Institute of Diabetes and Kidney Diseases. "Obesity increases the risk for type 2 diabetes and cardiovascular diseases, and these conditions can be more difficult to manage in young people," Mary Evans, program director of Division of Digestive Diseases and Nutrition at NDDK and study author, said in a news release. The surgery, however, does come with c...
Army researchers improve battery safety with new cathode chemistry

Army researchers improve battery safety with new cathode chemistry

Science
May 10 (UPI) -- Scientists with the U.S. Army have developed a new type of cathode chemistry that makes batteries safer and more efficient. Currently, soldiers must regularly carry batteries weighing between 15 and 20 pounds. But thanks to a new type of cathode and electrolyte, soldiers could soon be carrying safer and more efficient batteries weighing half as much. Army researchers were able to boost lithium-ion battery energy density by using a totally aqueous electrolyte. The electrolyte is free of transition metal and boasts high capacity energy storage. "Such a high energy, safe and potentially flexible new battery will likely give the Soldiers what they need on the battlefield: reliable high energy source with robust tolerance against abuse," Kang Xu, senior scientist at the U.S. Ar...
Revised guidelines improve survival rates for traumatic brain injury patients

Revised guidelines improve survival rates for traumatic brain injury patients

Health
May 8 (UPI) -- People suffering severe traumatic brain injury may have a better chance of surviving when emergency medical responders follow certain guidelines before getting to the hospital, new findings show. When EMS workers focused on preventing low oxygen, low blood pressure and hyperventilation, survival rates for severe TBI patients doubled, according to research published Wednesday in JAMA Surgery. Survival rates tripled for people with TBI when EMS workers inserted breathing tubes, the researchers say. "This demonstrates the significance of conducting studies in real-world settings and brings a strong evidence base to the guidelines," Patrick Bellgowan, program director at National Institute of Neurological Disorders and Stroke, said in a news release. "It suggests we can systema...
Cellular energy route finding may improve understanding of aging, chronic disease

Cellular energy route finding may improve understanding of aging, chronic disease

Health
Jan. 7 (UPI) -- Scientists have found a cellular route for energy that could shed more light on how humans age and develop chronic diseases. Researchers from the Washington University of St. Louis have uncovered a once unknown path for nicotinamide mononucleotide, or NMN, which helps fuel the human body, according to a new study published Monday in Nature Metabolism. "To achieve such fast uptake of NMN into the tissues, we speculated that there must be a specific NMN transporter that moves NMN directly into cells, even though no one had ever seen such a thing," Shin-ichiro Imai, a professor of developmental biology at Washington University, said in a news release. For this protein highway, the researchers found that cells must create a molecular transport system. First, NMN provides energ...
