China finds more cases of African swine fever on Hainan island
China has detected new cases of African swine fever in six farms across four locations in Hainan province, the agriculture ministry said on Sunday, adding to two earlier cases of the contagious disease identified in the province on Friday. The disease, which is fatal to pigs but harmless in humans, has spread to every province on the Chinese mainland since its initial detection in August 2018.
FDA approves Teva's generic nasal spray to treat opioid overdose
Generic drugmaker Teva Pharmaceutical Industries Ltd on Friday received approval from the U.S. Food and Drug Administration (FDA) to market its generic nasal spray for opioid overdose, the health regulator said. This is the first approval of a generic naloxone nasal spray for use in a community setting by individuals without medical training, the FDA said in a statement.
Older people feel more youthful when they also feel in control
Older adults may feel younger than their age on days when they feel most in control of their lives, a small study suggests. People who believe they can influence the outcomes and events in their daily lives generally do feel a greater sense of control than those who feel more helpless, and previous research has linked a strong sense of control to better wellbeing, researchers note in Journals of Gerontology: Psychological Sciences.
Second death in Novartis gene therapy trials under investigation
Novartis AG, which this week announced positive interim trial results for its experimental gene therapy for spinal muscular atrophy, on Friday said investigation is underway into whether a second trial death could be related to the treatment. Novartis has filed for U.S. Food and Drug Administration approval of the gene therapy, Zolgensma, and a decision is expected within weeks. The FDA submission was based on findings from a trial of 15 babies treated with Zolgensma.
China draws up tighter rules on human gene and embryo trials: Xinhua
China's top legislature will consider tougher rules on research involving human genes and embryos, the first such move since a Chinese scientist sparked controversy last year by announcing he had made the world's first "gene-edited" babies. He Jiankui, associate professor at Southern University of Science and Technology in Shenzhen, attracted condemnation from the global scientific community when he said he had used a technology known as CRISPR-Cas9 to alter the embryonic genes of twin girls born in November.
Sleep myths may hinder good sleep and health
Widespread beliefs about sleeping include advice on how much sleep is enough, what quality sleep means and how to achieve it, but when these pronouncements are wrong, they can do more harm than good, researchers argue. The study team gathered the most common sleep "myths" and asked sleep-science experts to rank them according to how wrong they were, and how bad it might be for a person's health to follow the advice.
Higher state minimum wage tied to lower suicide rates
Suicide rates grow more slowly in states that increase their minimum wage, according to a U.S. study that suggests this might be one strategy for curbing deaths by suicide. Although a small proportion of the population works for minimum wage, people living in low-income households have a higher risk of suicide than more affluent people, researchers note in the American Journal of Preventive Medicine. Raising the minimum wage has been linked to a number of positive outcomes for low-income Americans including higher odds of graduating high school and lower odds of having unmet medical needs.
