For all their risks, opioids had no pain-relieving advantage in a yearlong clinical trial

The LA Times

For years, doctors turned to opioid painkillers as a first-line treatment for chronic back pain and aches in the joints. Even as the dangers of addiction and overdoses became more clear, the drugs’ pain-relieving benefits were still thought to justify their risks. Now researchers have hard data that challenges this view.

U.S. Immigration Policy Threatens Shake-Up In Home Health Business


On a rare rainy night in Albuquerque, two dozen students are learning the proper way to care for older people. Teacher Liliana Reyes is reviewing the systems of the body — circulatory, respiratory and so on — to prepare them for an upcoming exam. These students are seeking to join a workforce of about 3 million people who help older adults remain in their homes. They assist these clients with things like bathing, dressing, and taking medication on time. About a quarter of these workers are immigrants.


FDA strengthens warning on opioid cold medicine


The FDA announced Thursday that it’s requiring revisions to the safety labeling on such prescription opioid cough and cold medicines to indicate that the products no longer can be used to treat children — because their risks outweigh their potential benefits — and should be used only for adults 18 and older.

Worms living in your veins? Seventeen volunteers said ‘OK’


A research group in the Netherlands is infecting healthy volunteers with Schistosoma mansoni, one of five tiny waterborne worm species that cause schistosomiasis. They hope to create a human model that could help speed up the development of new drugs and vaccines against the disease, which sickens millions of people and kills thousands each year. The team says the risk to volunteers is very low because the study is designed to prevent the parasites from reproducing. But some scientists argue that it’s not low enough because there is no guarantee that subjects will get rid of their parasites when the study is over.


Opioid makers gave $10 million to drug advocacy groups amid epidemic

NBC News

Companies selling some of the most lucrative prescription painkillers funneled millions of dollars to advocacy groups that in turn promoted the medications’ use, according to a report released this past week by a U.S. senator.


World’s first human-sheep hybrids pave way for diabetes cure and mass organ transplants

The Telegraph

The next step is to implant human stem cells into sheep embryos which have been genetically modified so they cannot grow a pancreas, in the hope that human DNA will fill in the missing code. If successful a human pancreas should appear inside the animal’s body. The team is about to apply for permission from regulators to lengthen their experiment to 70 days to see if the human cells really can create an organ.


Nursing homes sedate residents with dementia by misusing antipsychotic drugs, report finds

Why science blogging still matters


Science blogs have been around since the early 2000s, and in recent years the ‘microblogging’ platform Twitter and other social-media channels, which require less time to maintain than does a full blog, threatened to make them obsolete. But some scientists are keeping the practice alive, and it continues to play a major part in sparking collaborations, conveying crucial information and strengthening scientific communities.


Gene therapy field hit by fresh safety concern


A virus that buoyed the gene therapy field when it led to dramatic benefits in babies born with a fatal neuromuscular condition is under scrutiny. A small animal study suggests that high doses of the virus, called adeno-associated virus 9, can cause severe liver and neuron damage in young monkeys and pigs. The results drew attention in part because they come from the lab of James Wilson at the University of Pennsylvania, who led a 1999 trial in which a teenager died from an immune reaction to a different gene therapy vector.
