National Health 'Agency' to 'Authority': Ayushman Bharat Body Restructured

The agency was responsible for running the government’s massive new health insurance scheme and is now being called an “authority” in an effort to enhance the autonomy of the body.  The cabinet has approved the “restructuring” of the National Health Agency as the National Health Authority, and has dissolved the former.

AIDS Epidemic: More Insights Could Inform Our Response to Opioid Crisis

There are important lessons to be learned from the successes and failures of the AIDS response that could inform our response to the epidemic opioid, according to a paper by researchers at the Columbia University Mailman School of Public Health.

Decades of HIV research have demonstrated that the existence of an effective biomedical treatment is rarely, in and of itself, sufficient to combat an epidemic, suggesting that both a social as well as a biomedical response to the opioid crisis are necessary in order to be effective . The paper is published in the  New England Journal of Medicine .

'Zombie cells' Play Role in Anxiety: Findings

Mayo Clinic researchers and collaborators have shown that the obesity increases the level of "zombie" or senescent cells in the brain, and that those cells, in turn, are linked to anxiety. When senolytic drugs are used to clear those cells, the anxious behaviors in the mice dissipate. These findings appear in  Cell Metabolism .

Psychiatric Disorders: Disrupted Networks Link Overlapping Cognitive Deficits

Psychiatric disorders share common alterations of functional connectivity between three core brain networks involved in cognition, according to a meta-analysis published in  Biological Psychiatry . The network alterations were localized in brain regions underlying general cognitive performance. The study suggests that the alterations in these networks contribute to the cognitive dysfunction present in multiple psychiatric disorders.

Evolution of Metabolism: Fruit Flies Help to Shed Light

Researchers have discovered that the ability to use sugar as food varies strongly related closely related to fruit fly species. They have also identified the genetic basis of this variation. In the future, it will be interesting to explore whether human populations with different dietary histories may respond differently to modern diets rich in sugars.
