 Why do not researchers report what is in placebos?

Efectos placebo y nocebo (Photo: Sertox )

Placebos: what they’re made of matters. By Jeremy Howick*. theconversation.com. October 01, 2019. Placebo controls are a gold standard against which new treatments are often measured. If a new treatment consistently proves to be better than a placebo and safe, it can be marketed, sold and prescribed. Otherwise, it can’t – or at least shouldn’t. The problem is that, as our latest study reveals, researchers don’t report what placebos contain. Different placebos have different effects, and the choice of what’s in a placebo can lead to mistaken inferences about a new treatment’s benefits or harms.

Antibiotic resistance surges in dolphins, mirroring humans. 13 years of antibiotic resistance trends in bottlenose dolphins. sciencedaily.com. September 15, 2019. Summary: Scientists obtained a total of 733 pathogen isolates from 171 individual wild Bottlenose dolphins in Florida and found that the overall prevalence of resistance to at least one antibiotic for the 733 isolates was 88.2%. Resistance was highest to erythromycin, followed by ampicillin. It is likely that these isolates from dolphins originated from a source where antibiotics are regularly used, potentially entering the marine environment through human activities or discharges from terrestrial sources.
