Election stress can hurt your heart
Election stress is in full effect, and it can take a heavy toll on our heart health. Stressful situations produce a surge of hormones in our bodies that can elevate our blood pressure and heart rate and speed up our breathing.“This reaction is the normal way the body prepares to deal with a stressful situation,” said Dr. Megan Kamath, a cardiologist at UCLA Health. “However, these symptoms should not be ignored, as stress ineven a healthy person can cause significant damage to one ’s health.”In terms of triggering stress or exacerbating preexisting heart conditions, the election is on par with other traumatic epi...

UCLA researchers study genetics ’ role in COVID-19 susceptibility, severity
“One of the most troubling things about COVID-19 is that we have a limited ability to predict how sick a specific individual will get,” said Dr. Daniel Geschwind.Geschwind is the MacDonald Distinguished Professor in Human Genetics at theDavid Geffen School of Medicine at UCLA and a member of theEli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. And he ’s part of a team of UCLA scientists conducting research to learn why certain people get sick from the virus that causes COVID-19 — and why others don’t.Millions of people around the world have been infected with SARS-CoV-2, the v...

New study pinpoints how the brain ’s inner clock measures seconds
FINDINGSUCLA neuroscientistsstudying how the brain measures time in secondsintroduced mice to two different scents. The mice learned that one odor predicted the arrival of a sweet liquid reward after three seconds, while the other predicted the reward after six seconds.The mice started licking the spout earlier in anticipation of the reward after they sniffed the first scent than when they smelled the second.While the mice responded to the two stimuli, researchers observed activity intwo regions of their brains: the striatum and the premotor cortex,which provides input to the striatum. They found that while both regions en...

How our brains create breathing rhythm is unique to every breath
Breathing propels everything we do, so its rhythm must be carefully organized by our brain cells, right?Wrong.Every breath we take arises from a disorderly group of neurons — each one like a soloist belting out its song before it unites with other neurons to harmonize on a fresh breath.That ’s the gist ofa UCLA study published March 3 in the online edition of Neuron.“We were surprised to learn that how our brain cells work together to generate breathing rhythm is different every time we take a breath,” saidJack Feldman, the study ’s senior author, a professor of neurobiology at the David Geffen School of Medic...

Blood test identifies risk of disease linked to stroke and dementia
A UCLA-led study has found that levels of six proteins in the blood can be used to gauge a person ’s risk for cerebral small vessel disease, or CSVD, a brain disease that affects an estimated 11 million older adults in the U.S. CSVD can lead to dementia and stroke, but currently it can only be diagnosed with an MRI scan of the brain.“The hope is that this will spawn a novel diagnostic test that clinicians can start to use as a quantitative measure of brain health in people who are at risk of developing cerebral small vessel disease,” said Dr. Jason Hinman, a UCLA assistant professor of neurology and lead author of t...

Many take anticoagulants and OTC supplements, which poses risk
FINDINGSNearly 98% percent of people prescribed direct-acting oral anticoagulants such as apixaban also used over-the-counter products. Of those, 33% took at least one such product that, in combination with the anticoagulants, could cause dangerous internal bleeding. People taking these medications largely lacked knowledge of some potentially serious interactions.BACKGROUNDDirect-acting oral anticoagulants are the drug of choice for stroke prevention in patients with atrial fibrillation, which occurs most frequently in older patients. Apixaban is one of the most frequently prescribed. However, most people prescribed apix...

Study shows how serotonin and a popular anti-depressant affect the gut ’s microbiota
In this study, we were interested in finding out why they might do so,” said Hsiao, UCLA assistant professor of integrative biology and physiology, and of microbiology, immunology and molecular genetics in the UCLA College; and of digestive diseases in the David Geffen School of Medicine at UCLA.Hsiao and her research group reported in the journal Cell in 2015 that in mice, a specific mixture of bacteria, consisting mainly of Turicibacter sanguinis and Clostridia, produces molecules that signal to gut cells to increase production of serotonin. When Hsiao’s team raised mice without the bacteria, more than 50% of t...

Treating stroke patients just 15 minutes earlier can save lives
Initiating stroke treatment just 15 minutes faster can save lives and prevent disability, according to a new UCLA-led study, published today inJAMA. The research also determined that busier hospitals — those that treat more than 450 people for stroke each year — have better outcomes than those that treat fewer than 400 stroke patients per year.Researchers at the David Geffen School of Medicine at UCLA and five other institutions in the U.S. and Canada, examined data for 6,756 people who experienced ischemic strokes. The patients ’ median age was 71, and 51.2% were women.The researchers looked at stroke patients ’...

Nerve stimulation could provide new treatment option for most common type of stroke
Research led by a UCLA scientist found that a new nerve stimulation therapy to increase blood flow could help patients with the most common type of stroke up to 24 hours after onset.A study of 1,000 patients found evidence that the technique, called active nerve cell cluster stimulation, reduced the patients ’ degree of disability three months after they suffered an acute cortical ischemic stroke, which affects the surface of the brain.Dr. Jeffrey Saver, director of theUCLA Comprehensive Stroke Center, was the co-principal investigator of the study, which was conducted at 73 medical centers in 18 countries.“We believe ...

A missing gene makes a big difference in patients ’ recovery from mild stroke
More than 6 million Americans live with disabilities following a stroke. Even mild strokes can leave survivors with arm and leg weakness, poor muscle control and memory lapses that worsen with age. Now UCLA neuroscientists have found that patients born without a gene called CCR5 recover better from mild stroke than patients with the gene. The team partnered with Israeli researchers to study the missing gene ’s effect on brain function.Published Feb. 21 in the journal Cell, the findings could lead to the first pill to reverse the physical and mental aftermath of mild stroke.“This is the first time that a human gene h...

How to stay healthy and happy through the decades
Successful aging can be the norm, says UCLA psychology professor Alan Castel in his new book, “Better with Age: The Psychology of Successful Aging” (Oxford University Press). Castel sees many inspiring role models of aging. French Impressionist Claude Monet, he notes, began his beloved water lily paintings at age 73.Castel cites hundreds of research studies, including his own, combined with personal accounts from older Americans, including Maya Angelou, Warren Buffett, John Wooden, Bob Newhart, Frank Gehry, David Letterman, Jack LaLanne, Jared Diamond, Kareem Abdul-Jabbar, John Glenn and Vin Scully.Castel notes that ar...

New therapy spurs nerve fibers to regrow through scar tissue, transmit signals after spinal cord injury in rodents
Neuroscientists at UCLA, Harvard University and the Swiss Federal Institute of Technology have identified a three-pronged treatment that triggers axons — the tiny fibers that link nerve cells and enable them to communicate — to regrow after spinal cord injury in rodents. Not only did the axons grow through scars, they could also transmit signals across the damaged tissue.If researchers can produce similar results in human studies, the findings could lead to a therapy to regrow axon connections in people living with spinal cord injury, potentially restoring function. Nature publishes the research in its Aug. 29 onl...
