From Phys.org/Univ. of Michigan (June 9, 2020):
“On a high-sugar diet, we find that the fruit flies’ dopaminergic neurons are less active, because the high sugar intake decreases the intensity of the sweetness signal that comes from the mouth,” Dus said. “Animals use this feedback from dopamine to make predictions about how rewarding or filling a food will be. In the high-sugar diet flies, this process is broken—they get less dopamine neuron activation and so end up eating more than they need, which over time makes them gain weight.”
It is well known that consuming food and drink high in sugar is not great for us, but scientists are continuing to unravel the intricacies of how the sweet stuff drives negative health outcomes. The latest finding comes from researchers at the University of Michigan, who through studies in fruit flies have found that excess amounts of sugar can shut down crucial neural circuits linked to regulating satiety, possibly leading to overeating in humans.
For instance, more hospitals are remotely triaging and registering patients before they even arrive. Clinicians can consult with patients from their home via telemedicine to help determine how sick they are and if they need to come to the ER at all. From there, admissions are made with as little contact with staff or other patients as possible.
With the potential for resurgences of the coronavirus, and some scientists warning about outbreaks of other infectious diseases, hospitals don’t want to be caught flat-footed again. So, more of them are turning to new protocols and new technology to overhaul standard operating procedure, from the time patients show up at an emergency room through admission, treatment and discharge.
