All Sauce from Weekly Gravy:

The U.S. Centers for Disease Control and Prevention has resumed a national campaign that uses the stories of former smokers to warn Americans about the many health dangers of tobacco. Known as the “Tips From Former Smokers” campaign, seven new people are featured in ads sharing their stories about how cigarette smoking damaged their health. One tactic is new in this latest round of ads: They take direct aim at the harms of menthol cigarettes, which have become popular among minorities and in marginalized communities. “Many of this year’s new ads include messaging about the harms of menthol cigarettes, which can contribute to tobacco-related health disparities,” the agency noted in a news release. “Menthol in cigarettes can make it easier to start smoking and harder to quit.” Tammy W. is one of the former menthol cigarette smokers featured in the campaign. An avid runner, the 50-year-old ate healthy and avoided drugs and alcohol but had a “side hobby” of smoking menthol cigarettes — like many members of her Little Travers Bay Bands of Odawa Indians tribe. After having chest pains during a daily 10-mile run when she was 44, she went to see her doctor and was told she needed open-heart surgery immediately. During the operation, she flatlined three times and had a stroke. She has since recovered, but she can no longer run as far.…  read on >  read on >

Scientists say they’ve created the first 3D-printed brain tissue where neurons network and “talk” to each other. The breakthrough could be an advance for studying neurological processes in the lab, say a team from the University of Wisconsin-Madison. “This could be a hugely powerful model to help us understand how brain cells and parts of the brain communicate in humans,” said study lead author Su-Chun Zhang, a professor of neuroscience and neurology at UW–Madison’s Waisman Center. “It could change the way we look at stem cell biology, neuroscience and the pathogenesis of many neurological and psychiatric disorders,” he added in a university news release. Zhang’s team noted that researchers already have an organic model for brain research, called brain organoids. But organoids grow with much less cellular organization and inter-connective ability than the new 3D-printed tissue. With his lab’s new process, “we printed the cerebral cortex and the striatum, and what we found was quite striking,” Zhang said. “Even when we printed different cells belonging to different parts of the brain, they were still able to talk to each other in a very special and specific way.” Reporting Feb. 1 in the journal Cell Stem Cell, the Madison team said their 3-D printing technology has improved on prior attempts to create 3D-printed brain tissue. The Madison lab’s tissues include neurons created from stem cells, and…  read on >  read on >

Police seizures of “magic” mushrooms have more than tripled within the past five years, the U.S. National Institute on Drug Abuse reports. The total weight of psilocybin mushrooms seized by law enforcement increased from 498 pounds in 2017 to 1,861 pounds in 2022, according to a new report published Feb. 6 in the journal Drug and Alcohol Dependence. To put those seizures in perspective, a typical dried mushroom dose in clinical trials for psilocybin therapy runs between 2.5 grams (.08 ounces) to 6 grams (.2 ounces), according to a 2022 analysis in the journal Frontiers in Psychiatry. These seizures come in the midst of a surge in public interest regarding the use of psilocybin for therapy and recreation, researchers said. “While psilocybin is by no means the most dangerous drug, recreational use can come with unforeseen risks such as bad trips,” said lead researcher Joseph Palamar, an associate professor of epidemiology at the NYU Grossman School of Medicine.  “Research studies suggesting its effectiveness in treating mental health issues and extensive positive media coverage may lead some people to seek ‘shrooms’ outside of medical contexts,” Palamar added. “People who use psilocybin outside of medical supervision need to be educated about risks associated with use.” In 2018 and 2019, the U.S. Food and Drug Administration granted breakthrough therapy status to research using psilocybin as a treatment for…  read on >  read on >

The former ‘party drug’ ketamine has gotten some good press recently, with clinical trials suggesting it might be a powerful and fast-acting antidepressant. Now, one of the first “real-world” studies of ketamine against depression appears to support those findings. Researchers at the University of Michigan and the VA Ann Arbor Healthcare System say that almost half of 215 veterans who’d been suffering severe, treatment-resistant depression benefited from six weeks of ketamine infusions. “It’s not a silver bullet,” stressed study lead author Dr. Paul Pfeiffer. “But when we see these patients in our clinic, who have been through every treatment available and nothing has worked, to have even a quarter achieve a significant measurable response is very good. We routinely get thanked for making a difference in their lives.”  Pfeiffer led the study with Dr. Avinash Hosanagar. Both are faculty at the U-M Medical School department of psychiatry, and both treat patients in the VA Ann Arbor Healthcare System. The veterans involved in the new study were selected because they’d all tried and failed multiple treatments to curb their severe depression. Many had other mental health issues, such as post-traumatic stress disorder (PTSD), anxiety or a history of alcohol or drug abuse. The Michigan researchers had each of the patients receive ketamine infusions beginning in 2019 or the first nine months of 2020. Their outcomes were tracked…  read on >  read on >

They say money can’t buy happiness – and now a new study of Indigenous peoples around the world backs up that assertion. People living in small-scale societies on the fringes of the modern world lead lives as happy and satisfying as folks from wealthy, technologically advanced nations, researchers report Feb. 5 in the Proceedings of the National Academy of Sciences. “Surprisingly, many populations with very low monetary incomes report very high average levels of life satisfaction, with scores similar to those in wealthy countries,” said lead researcher Eric Galbraith, a professor with McGill University in Montreal. This runs counter to the notion that economic growth is a sure-fire way to increase the well-being of people in low-income countries, researchers noted. Global surveys have found that people in wealthier countries tend to report higher levels of life satisfaction than those in poorer countries, researchers said in background notes. However, these global polls tend to overlook people in societies where the exchange of money plays a minimal role in everyday life, and where livelihoods depend directly on nature, researchers said. For this study, researchers surveyed nearly 3,000 people from Indigenous or primitive communities at 19 sites around the world. Only 64% of the surveyed households had any cash, researchers said. And yet, their average life satisfaction scores were 6.8 on a 10-point scale across all communities, and…  read on >  read on >

Age-related macular degeneration can lead to vision loss in seniors, but new therapies have offered fresh hope for preserving eyesight later in life, eye experts say. These cutting-edge therapies benefit both the dry and wet types of age-related macular degeneration (AMD), says the American Society of Retina Specialists (ASRS). Eleven million people in the United States have AMD, with dry AMD affecting about 85% and wet AMD striking 15%. “Patients often tell me they are sure they will lose their vision because they have a family member who experienced vision loss from AMD, but with early diagnosis and treatment, we now have much more than hope to offer patients with wet or dry AMD,” ASRS Foundation President Dr. Judy Kim said in a news release. The macula is a round area at the center of the retina, which is the layer of light-sensitive cells at the back of the eyeball that capture images. People with AMD slowly begin to lose their central vision, according to the American Academy of Ophthalmology. They can’t see fine details either up close or far away, but their peripheral vision remains normal. The AAO gives the example of looking at a clock with hands. People with AMD might see the clock’s numbers, but not the hands. Most patients have early or intermediate dry AMD, which can remain stable for a…  read on >  read on >

New research suggests healthy lifestyles can help stave off dementia, perhaps by building a resilient ‘cognitive reserve’ in the aging brain. The study was based on the brain autopsies on 586 people who lived to an average age of almost 91. Researchers compared each person’s lifestyle and end-of-life mental skills to their neurological signs of dementia, such as brain protein plaques or changes in brain blood flow. None of these brain factors seemed to greatly affect the positive connection between healthy living and a person’s end-of-live mental skills, said a team led by Dr. Klodian Dhana, of Rush University Medical Center in Chicago. That means that good nutrition, regular exercise and other factors may instead “provide a cognitive reserve” that buffers against negative changes going on within the brain — allowing older folk to “maintain cognitive abilities” over time, the researchers said. “You can almost sort of cheat the biology a little bit and still not get the symptomatology as early” as someone who’s less healthy, said Dr. Liron Sinvani, who wasn’t involved in the study. She directs geriatric hospitalist services at Northwell Health in Uniondale, N.Y. The study was published Feb. 5 in the journal JAMA Neurology. As Dhana’s group notes, it’s long been known that certain lifestyle choices — eating well, exercising, avoiding smoking and heavy drinking — are linked to lower rates…  read on >  read on >

Police killings of unarmed Black people are robbing the Black community of a precious commodity – sleep. Black adults across the United States suffer from sleep problems after they’re exposed to news of killings that occur during police encounters, a new study published Feb. 5 in the journal JAMA Internal Medicine finds. Specifically, Black adults experienced increases in short sleep, lasting fewer than seven hours a night, and very short sleep of less than six hours nightly. “These findings show that poor sleep health is another unfortunate byproduct of exposure to these tragic occurrences,” said lead researcher Dr. Atheendar Venkataramani, an associate professor of medical ethics and health policy at the University of Pennsylvania’s Perelman School of Medicine in Philadelphia. “Exposure of Black Americans to police violence — which disproportionately effects Black individuals — adversely impacts sleep health of these individuals, a critical keystone that further impacts our mental, physical and emotional well-being,” Venkataramani added in a university news release. For the study, researchers analyzed changes in sleep duration tracked by two separate federal surveys, and tied those changes to data on officer-involved killings around the nation. Results showed that about 46% of Black adults reported short sleep versus 33% of white respondents. For very short sleep, the numbers were 18.4% for Black adults and 10.4% for whites. Researchers speculated that awareness of the deaths…  read on >  read on >

If you’re over 65, you likely struggle sometimes to hear conversations clearly, but ignoring that may prompt even more serious health problems, experts say. If left unchecked, hearing loss can lead to social isolation and depression — two conditions known to raise dementia risk, said Dr. Leah Ross, a physician in the Division of Geriatric Medicine at Penn State Health’s Milton S. Hershey Medical Center. Hearing impairment is the third most common chronic condition faced by older adults, Ross said. Yet, only 20% of these folks have had a hearing test in the past five years, according to the American Speech-Language-Hearing Association. While more than half of adults acknowledge they struggle with hearing problems, only 11% have sought treatment. “A lot of times, people are suffering with hearing impairment for years before they even say anything to their doctors,” Ross noted in a Penn State news release. The good news? “It is a modifiable risk factor,” Ross said. “There’s something we can do about it.” What’s missed by not treating hearing loss is what it can trigger, Ross explained. In her practice, she often sees this familiar scenario: An older adult with hearing loss discovers his or her hearing has declined to the point where they have trouble understanding conversations. They start to skip social events and stay at home, as their world shrinks and…  read on >  read on >

Unprovoked shark attacks increased slightly worldwide last year, but twice as many people died from shark bites as the year before, new data show. There were 69 unprovoked shark attacks in 2023, higher than the five-year average of 63 attacks per year, according to the University of Florida’s International Shark Attack File. Ten of the attacks in 2023 proved fatal, up from five the year before, researchers said. “This is within the range of the normal number of  bites, though the fatalities are a bit unnerving this year,” said Gavin Naylor, director of the Florida Museum of Natural History’s shark research program. Australia suffered a disproportionate number of shark bite deaths, the researchers noted. The continent accounted for 22% of all attacks but made up 40% of fatalities. Other shark attack deaths occurred in the United States, the Bahamas, Egypt, Mexico and New Caledonia, researchers said. The United States had 36 unprovoked shark attacks, accounting for 52% of incidents worldwide. Of those, two attacks were fatal, one in California and another in Hawaii. As has been the case in previous years, Florida had more shark bites than any other state, with 16 attacks. Confirmed non-fatal bites also happened in Costa Rica, Colombia, Brazil, New Zealand, Seychelles, Turks and Caicos, Ecuador and South Africa. This annual report focuses primarily on unprovoked attacks, although the database documents all…  read on >  read on >
