Researchers found that adults who did moderate-intensity walking for 120 minutes or less per week were at a reduced likelihood of dying prematurely from all causes, compared with inactive individuals, while higher levels of walking were tied to a 20% lower mortality risk. The findings in the American Journal of Preventive Medicine, based on data on more than 139,000 adults enrolled in the Cancer Prevention Study II Nutrition Cohort, showed that the age-standardized overall death rate among those who walked less than the recommended amount of physical activity was 2,851 per 100,000, compared with 4,293 per 100,000 among inactive participants.
People have a soft spot for the classic sad puppy face, and dogs are more likely to adopt the expression when a person is looking at them, a study published in Scientific Reports found. The expression potentially taps into human emotions, but the study did not show that dogs change expression to manipulate people, study leader Juliane Kaminski said.
Biologists in Nebraska have relied on an aging Chesapeake Bay retriever named Train to find mountain lion scat for genetic analysis, leading to the development of population models on which a proposed mountain lion management plan would be based. Train works for belly rubs, tug-of-war games and the occasional peanut butter sandwich.
Federal authorities are enforcing a ban on animals weighing more than 20 pounds on airplanes leaving San Juan, Puerto Rico, forcing some 2,000 hurricane refugees to abandon their pets, says Sylvie Bedrosian, president of Pet Friendly Puerto Rico. The No Pet Left Behind FEMA Act "authorizes FEMA to provide rescue, care, shelter, and essential needs for individuals with household pets and service animals, and to the household pets and animals themselves following a major disaster or emergency," and the embargo violates that act, Bedrosian says, but an employee with one airline says it has received a waiver effective through Oct. 31.
Senate health committee Chairman Lamar Alexander, R-Tenn., and Sen. Patty Murray, D-Wash., announced Thursday that 12 Republicans and 12 Democrats signed on to co-sponsor their bipartisan deal aimed at stabilizing the Affordable Care Act markets. Alexander expects the proposal to "become law in some fashion before the end of the year," despite a lack of commitment by Senate Majority Leader Mitch McConnell, R-Ky., to bring it to the Senate floor for a vote.
The crude rate of major adverse cardiac events was higher among patients with acute coronary syndromes and diabetes at 25.9%, compared with 16.3% and 16.1% among those with prediabetes and normal glucose metabolism, respectively, according to a study in JACC: Cardiovascular Imaging. Researchers used a cohort of 547 ACS patients and found that an increased risk of MACE was associated with diabetes, but not with prediabetes.
Researchers found a higher likelihood of developing incident type 2 diabetes among at-risk adults who received statin therapy prior to being diagnosed with diabetes. The findings in BMJ Open Diabetes Research & Care, based on 3,234 participants in the Diabetes Prevention Program Outcomes Study, revealed that a longer duration of statin use was associated with a higher diabetes risk among those in the lifestyle intervention group than those in the metformin and usual care groups.
Imperial College researchers found that amyloid PET with F-18 florbetapir led to changes in diagnosis among patients with suspected Alzheimer's disease who didn't have amyloid buildup in the brain, as well as reduced the use of invasive tests to identify amyloid, such as cerebral spinal fluid analysis, among those with uncertain diagnosis. Amyloid PET may be most beneficial in evaluating younger patients with suspected early-onset dementia, whose symptoms may be different from those of older patients with the disease, researchers wrote in the Journal of Neurology, Neurosurgery & Psychiatry.
Cerveau Technologies has entered an agreement with Janssen Pharmaceuticals for research studies using its F-18 MK-6240, an investigational PET tracer for imaging neurofibrillary tangles in the brain, as a biomarker to diagnose neurodegenerative diseases and evaluate new treatments for them.
Registered dietitian nutritionist Faith Hicks says some common pediatric nutrition myths are that children do not develop hypertension or heart disease and that they should avoid common food allergens in their first year to prevent allergies. While it is true that green vegetables such as spinach and broccoli contain iron it is not readily absorbed, Hicks says, and putting children on a diet of bananas, rice, applesauce, tea and toast may not be the best way to resolve diarrhea.
