Patients at high risk for psychiatric symptoms after a stay in the intensive care unit

Yes, if you aren't already septic when you go in-  they will be sure to cut you and poke you and put lots of holes in your epithelium.   And expose you to all those antibiotic resistant microbes that live in hospitals.   And put you on a glucose drip too.
 

Lower-carb diet slows growth of aggressive brain tumor in mouse models
A high-fat, low-carbohydrate diet that included a coconut oil derivative helped reduce the growth of glioblastoma tumor cells and extended lifespan in mouse models by 50 percent, researchers found.
Glioblastoma, the most common brain tumor in adults, has no effective long-term treatment and on average, patients live for 12 to 15 months after diagnosis, according to the National Cancer Institute.
The findings are a new twist on an old idea: The so-called ketogenic diet has been used for nearly 90 years to help reduce epileptic seizures. Now, a high-fat, low-carbohydrate version of the ketogenic diet has been shown to slow glioblastoma tumors by cutting back on the energy supply they need to thrive, said Brent Reynolds, Ph.D. A glioblastoma tumor requires large amounts of energy as it grows, and the dietary intervention works by drastically limiting the tumor's supply of glucose, Reynolds said.   citation

HIV defies attempt to edit virus out of human cells with CRISPR
Vanquishing HIV just got that little bit harder. A promising technique to weaken the virus has in some cases made it stronger.
