(Reuters Health) - Workouts that mix up a variety of intense exercises with brief recovery periods in between may help people lose more weight than chugging along at a steady pace on a treadmill or exercise bike, a research review suggests. Doctors often advise people trying to lose weight to focus on cutting calories and getting more active. But the ideal type and amount of exercise for optimal weight loss isn't clear, researchers note in the British Journal of Sports Medicine. Chinese frozen food firm recalls products suspected of African swine fever contamination
Major Chinese frozen food producer Sanquan Food Co Ltd said on Monday it has recalled products that may be contaminated with African swine fever, following media reports that some of its dumplings tested positive for the virus. African swine fever is incurable in pigs but does not harm people. An epidemic of the disease has spread rapidly across China since August 2018, reaching 25 provinces and regions. Supply of primary care doctors linked with mortality rates
Mortality rates are lower in American communities with more primary care physicians than in areas of the country with fewer doctors, a study suggests. Overall in the U.S., the total number of primary care physicians rose from 196,014 in 2005 to 204,419 in 2015, the study found. But because of disproportionate losses of providers in rural areas, the average number of primary care physicians for every 100,000 people in the population declined from 46.6 to 41.1 during the same period. Brief general anesthesia appears safe for children's brains
(Reuters Health) - In infants, an hour of general anesthesia - long enough for most minor surgeries done in babies - doesn't increase the risk of impaired brain development compared to an hour of regional anesthesia, a study suggests. By age three, roughly one in 10 children in developed countries will have had general anesthesia at least once for things like repairing a hernia, placing ear tubes, removing tonsils or completing MRIs, researchers note in The Lancet. Merck, Pfizer drug combo extends kidney cancer survival: study
A combination of Merck & Co's immunotherapy Keytruda and Pfizer Inc's Inlyta helped patients with advanced kidney cancer live longer than those receiving and older Pfizer standalone therapy, according to data from a late-stage study presented on Saturday. Nearly 90 percent of patients who received the combination therapy were still alive after 12 months compared with about 78 percent of patients who were alive after a year when treated with the older drug Sutent, data showed. Japan approves test of iPS cells for treating spinal injuries
Japanese scientists will test the use of human-induced pluripotent stem cells (iPS) to treat spinal cord injuries, a health ministry panel that approved the research project said on Monday. The research team from Tokyo's Keio University planned to inject about two million iPS cells into the damaged areas of an individual patient and review the results over the course of a year, according to the plan approved by the health ministry.
