What mice in VR googles can tell us about our brains
Lab mice strapped to mini virtual reality googles are roaming through digital mazes in the latest breakthrough in neurobiology. And they hae a lot to teach us about how memory works. In pursuit of identifying the neurons in the brain that form memories, a team of researchers led by Daniel Dombeck, PhD, a professor in the university’s department of neurobiology, created miniature VR goggles to place on lab mice to study how they remember navigational cues when traversing digital mazes. “The most advanced instruments to image brain activity are large, table-top devices that cannot be carried around on a mouse’s head as they move through the environment. So instead, we hold the mouse’s head still under the large microscopes (so we can study their brains), and we let them run on a treadmill mounted under their limbs,” Dombeck said. He added that the movements of the treadmill move the animal through a virtual world displayed in the goggles, complete with twisting mazes and depictions of predators like owls. “With this set-up, we can then use our cutting-edge microscope systems to study brain activity during navigation,” Dombeck said. “We are trying to identify the exact neurons in the brain that are forming memories of the mazes, and in those neurons, we are trying to identify which synapses are being modified to form the memories and through what mechanisms those synapses are modified.”

Research shows a big increase in children taking melatonin.
New research shows a big increase in children taking melatonin to help with sleep. Pediatricians warn the long-term effects of the hormone supplement aren’t known. Nia Heard-Garris, MD is an assistant professor of pediatrics (advanced general pediatrics and primary care) at Northwestern University Feinberg School of Medicine and says she understands why desperate parents turn to melatonin to help their kids sleep. “I’m also a mom, so for all the parents out there with kids that have sleep issues, I get it.” However, she says given all the unknowns, the focus needs to be on sleep hygiene first, things like turning off screens at least an hour before bedtime, using blackout shades and not letting kids stay up more than an hour or two past their normal bedtime on weekends and vacations. “Now, if we’re at a situtation that we have tried everything – they’ve seen a sleep specialist; you know we’ve kind of done all the things – then I will prescribe melatonin.” Heard-Garris says parents should definitely talk to their pediatrician before giving kids melatonin because it’s possible to give too much. Signs of an overdose in kids include irritability, headaches, stomach pains and dizziness and severe drowsiness.

Doctor warns against using weight loss drugs without medical supervision
There are several medications approved by the FDA weight loss and/or diabetes. However, there have been overdoses and illnesses from improper use. “There are side effects, like any medication. It can slow down the way your stomach empties so people can feel nausea if you don’t do it correctly, or dose it correctly according to how your physician told you, you can throw up,” said Nidhi Kansal, MD, health system clinician of medicine (general internal medicine) at Northwestern University Feinberg School of Medicine. She continues about the importance of drug safety and using these drugs for the right reasons. “It’s not for aesthetics, it is about pure health, so it should be a discussion between you and your clinician on what is the reason for taking this.” Weight loss drugs aren’t new, but with increased accessibility it’s important to be in communication with your healthcare provider to avoid misuse or dosing accidents.

VR goggles aren’t just for people. Scientists built mini ones for mice.
Last week, Northwestern researchers revealed that they had created virtual reality lenses — each of which are 12 millimeters in diameter — that engross mice in virtual surroundings they believe are real. Researchers hope the goggles will expand findings on how mice and human brains process fear, anxiety and post-traumatic stress disorder. “As crazy as mouse goggles sound, this is exactly the sort of research that eventually trickles down to discoveries that have impacts on human health and disease,” researcher Daniel Dombeck told The Washington Post. Dombeck is a professor of neurology and neuroscience at Northwestern University Feinberg School of Medicine. “Our understanding of the brain is limited by technology,” Dombeck said. “And almost every time something new is invented to study the brain or behavior … we almost always find something new and unexpected.”

After Recalls and Infections, Experts Say Safer Eyedrops Will Require New FDA Powers
When you buy eyedrops at a U.S. store, you might assume you’re getting a product made in a clean, well-maintained factory that’s passed muster with health regulators. But repeated recalls involving over-the-counter drops are drawing new attention to just how little U.S. officials know about the conditions at some manufacturing plants on the other side of the world—and the limited tools they have to intervene when there’s a problem. The Food and Drug Administration is asking Congress for new powers, including the ability to mandate drug recalls and require eyedrop makers to undergo inspections before shipping products to the U.S. “These are very rare instances, but what we’ve seen is that these products can cause real harm,” said Timothy Janetos, MD, an ophthalmologist at Northwestern University. “Something needs to change.”

Heart Attacks Spike During Holidays: Tips to Protect Yourself
Late December is typically a time when holiday stress and winter weather can collide, creating a perfect recipe for a rise in heart attacks and stroke. “When we look across the year in terms of heart attack rates, what we see is fairly constant rates week by week with two exceptions: One is that there’s a broad, shallow dip in summer months and, two, there is a very short spike of about 30 to 40% in the last couple weeks of the year between Christmas and New Year’s,” said cardiologist Donald Lloyd-Jones, MD, chair of the department of preventive medicine at Northwestern University Feinberg School of Medicine. “During the holiday season, there are different stresses like dealing with your in-laws and travel arrangements that may add stress,” he explained in a Northwestern news release. “We’re often knocked off our eating and sleeping patterns, we tend to consume more alcohol, we’re not pursuing our typical physical activity and we may get thrown off our medication schedule.” If you experience any symptoms including face drooping, arm or leg weakness on one side or speech difficulty it’s time to dial 911. “If there’s any doubt, get checked out in person. At best, hopefully you are aborting a heart attack or stroke,” he said. “Time is heart muscle, time is brain cells, and so time is of the essence. The sooner you seek help in that situation, the sooner we can save your life or brain.”

Half of Diabetes Patients on Ozempic, Mounjaro Stop Using the Meds
Many Americans battling diabetes are turning to a new class of injected drugs that include blockbusters like Ozempic (semaglutide) and Mounjaro (tirzepatide). But a new study finds half of patients who use these “second line” therapiest – a class called GLP-1 RAs – quit them within a year. The main factor: Gastrointestinal issues like nausea, vomiting and diarrhea, according to the researchers. “Discontinuation is bad. It is common in all five types of [diabetes] medications, but we see significantly more in those prescribed the GLP-1 RAs,” said study lead author David Liss, PhD. He’s a research associate professor of general internal medicine at Northwestern University Feinberg School of Medicine in Chicago. People newly diagnosed with type 2 diabetes are typically first given a standby medication, metformin, to help manage their blood sugar. “Presumably, the doctor is saying, ‘You need to start a new medication to control your type 2 diabetes,’ and then within a year, half of them just stop and don’t start another one, and that’s not a good thing,” Liss said in a Northwestern news release. The study wasn’t designed to pinpoint why folks quit the drugs, although gastrointestinal side effects probably play a role, the researchers said.

Narcan: The new CPR? Local pharmacist wants to teach people how to use the life-saving nasal spray
In the midst of the national opioid crisis, access to Narcan, the nasal form of the opioid overdose antidote, is easier than ever. But would you know how to use it? Northwestern Medicine clinical pharmacist and assistant professor of orthopaedic surgery at Northwestern University Feinberg School of Medicine Sterling Elliott, PharmD, always has Narcan nasal spray on hand, because someone might need a life-saving opioid overdose reversal at any moment. “I’ve actually got two of these that I carry in the bag at any one time,” Elliott says. “If the need comes on, I know what I’m doing.” According to Elliott, “This is the new CPR, this is yet another way you could be a Good Samaritan and save somebody’s life.” Elliott noted, the Food and Drug Administration made the decision to let Narcan become an over-the-counter medication due to its non-harming nature. Administering it during an opioid overdose has little risk of harming the patient, but not giving it is a huge risk that could result in death. Bystanders who act in good faith in helping to administer Narcan are protected by Good Samaritan laws. If you want to have it on hand, Narcan nasal spray can be purchased at most pharmacies.

Northwestern Medicine giving Illinois patients ability to choose ‘X’ as sex designation
Patients at Northwestern Medicine’s hospitals and outpatients locations in Illinois will be able to choose “X” as a sex designation starting next week. Beginning December 8, people who are nonbinary, intersex or transgender can use “X,” instead of “M” or “F” as a sex designation on identification documents. The medical record will include designations for sexual orientation and gender identity to create a plan that will match a patient’s individual health needs. “Northwestern Medicine hospitals and outpatient centers affirm every patient’s gender identity,” said Sumanas Jordan, MD, PhD, director of the Gender Pathways Program at Northwestern Medicine and assistant professor of plastic surgery at Northwestern University Feinberg School of Medicine. “The new medical record designation will enhance communication with patients, align with best practices and help our staff better meet the needs of the diverse population we serve.”

‘COVID’ toes:’ Is the mysterious skin condition actually connected to the virus? Here’s what doctors say
With an uptick in COVID cases reported across Illinois this respiratory season, you might be on the lookout for certain symptoms in case you become ill. While people who’ve contracted the virus have reported a variety of symptoms, a fever, chills and a sore throat, other less common ones are possible. That includes “COVID toes,” a phenomenon that surfaced toward the onset of the pandemic. The mysterious skin condition that causes purple, blue or red discoloration in toes and occasionally fingers began popping up around the country early on during the pandemic, doctors with Northwestern Medicine previously said, leading some dermatologists to wonder if it may be connected to coronavirus. The swelling and discoloration can begin on one or several toes or fingers, Amy Paller, MD, chair of dermatology at Northwestern Feinberg School of Medicine, said in an article published by the American Academy of Dermatology. If you’re concerned that you have “COVID toes,” first you’ll want to take a COVID test to determine if you have contracted the virus. If you test positive, you’re encouraged to isolate and follow current Centers for Disease Control and Prevention recommendations.
