The U.S. Environmental Protection Agency has announced that it is cracking down on air pollution. Specifically, the agency introduced a tougher air quality standard that takes aim at fine particulate matter — the tiny bits of pollution that can penetrate the lungs — by lowering the allowable annual concentration of the deadly pollutant that each state can have. “This final air quality standard will save lives and make all people healthier, especially within America’s most vulnerable and overburdened communities,” EPA Administrator Michael Regan said in an agency news release announcing the change. “Cleaner air means that our children have brighter futures, and people can live more productive and active lives…” The EPA noted that “a broad and growing body of science” links particulate matter to serious, and often deadly, illnesses such as lung cancer, heart disease, kidney disease, neurological disorders, asthma attacks and stroke. Reaction to the new standard was enthusiastic. “The Biden administration is taking lifesaving action to protect people and rein in deadly pollution,” Abigail Dillen, president of the nonprofit law organization Earthjustice, said in the EPA news release. “The science is crystal clear. Soot, otherwise known as fine particle pollution, is a killer. It is driving heart disease, our asthma epidemic, and other serious illnesses. The people who suffer most are children and older Americans who live in communities of color and low-income… read on > read on >

Use It or Lose It? Mouse Study Reveals Key to Healthy Erections
Is ‘practice makes perfect’ true for the male erection, too? That’s the suggestion from a Swedish study involving amorous male mice. It found that getting erections regularly was important to the rodents’ overall erectile function. The key seemed to lie in connective tissue cells called fibroblasts. These cells have long been known to populate penile tissue, but their role has remained unclear, explained researchers from the Karolinska Institute in Stockholm. “Fibroblasts are the most abundant cells in the penis of both mice and humans, but they have been neglected in research,” said study lead author Eduardo Guimaraes, a researcher at the department of cell and molecular biology at Karolinska. “Now we can show, using a very precise method called optogenetics, that they have a very important role in regulating blood flow in the penis, which is what makes the penis erect,” he said in an institute news release. The findings were published Feb. 8 in the journal Science. Of course, many studies conducted in mice don’t translate to humans. But the Swedish team said that — size aside — the penises of mice and men aren’t dissimilar. “The basic mechanisms of erection are very similar in all mammals regarding anatomy, cell structure and so on,” principal investigator Christian Göritz explained. “However, there is one difference between humans and most mammals — they have a bone… read on > read on >
Stress Main Factor Driving Teens to Abuse Drugs, Alcohol
American teenagers cite stress as the leading reason they might get drunk or high, a new report reveals. That only underscores the need for better adolescent mental health care, according to the research team behind the study. Better “access to treatment and support for mental health concerns and stress could reduce some of the reported motivations for substance use,” concluded investigators from the U.S. Centers for Disease Control and Prevention. In the study, a team led by CDC researcher Sarah Connolly looked at 2014-2020 data on over 9,500 people ages 13 to 18, all of who were being treated for a substance use disorder. Teens were using a myriad of substances, including alcohol, marijuana, prescription painkillers (often opioids), prescription stimulants (for example, Ritalin), or prescription sedatives (such as Valium or Xanax). The teens were also asked why they thought they were using or abusing substances. Easing stress in their lives was the leading factor cited. “The most commonly reported motivation for substance use was “to feel mellow, calm, or relaxed” (73%), with other stress-related motivations among the top reasons, including “to stop worrying about a problem or to forget bad memories” (44%) and “to help with depression or anxiety” (40%),” Connolly’s team reported. Stress relief wasn’t the only motivator, of course: Half of the teens reported using substances “to have fun or experiment.” This reason… read on > read on >
Dementia Care Costs Can Quickly Burn Through People’s Savings: Study
Dementia care can eat through the savings of cash-strapped seniors, a new study warns. The average senior with dementia in non-nursing residential care facilities spent 97% of their monthly income on long-term care, researchers found. Meanwhile, those living in nursing homes spend nearly 83% of their monthly income on their care, results show. “Because dementia is such an expensive illness, it really is in a category of its own when we start to think about funding for long-term care,” said senior study author Jalayne Arias, an associate professor in the Georgia State University School of Public Health. “Our study shows that if you compare people with dementia to their age-matched counterparts, they experience costs that are untenable to manage,” Arias added in a university news release. For the study, researchers analyzed data from a national sample of more than 4,500 adults aged 70 and older, focusing specifically on out-of-pocket expenses for dementia care. “It’s really striking to see that the [average] individual with dementia is basically putting nearly all of their income toward long-term care,” said lead researcher Jing Li, an assistant professor of health economics at the University of Washington School of Pharmacy. “We hear about this anecdotally, but to get confirmation of that from the data is really concerning.” On average, seniors with dementia paid $3,090 a month out-of-pocket for non-nursing residential care… read on > read on >
How Would an FDA Ban on Popular Cold Meds Affect Americans?
America’s most popular cold medications contain a nasal decongestant that doesn’t work, creating a knotty dilemma for regulators, a new study reports. Cold remedies containing phenylephrine remain consumers’ most popular choice, despite decades of concern that the decongestant simply isn’t effective, researchers say. The U.S. Food and Drug Administration is considering whether to pull phenylephrine from store shelves, after a key advisory panel voted unanimously in September 2023 that the drug does nothing to clear stuffy noses. But such a move could create a wave of supply chain disturbances that would leave sick consumers without ready over-the-counter options, researchers report Feb. 8 in the Journal of the American Medical Association. Phenylephrine tends to be combined with other drugs that are effective — analgesics, cough suppressants and antihistamines — and sold as a multi-symptom product, researchers said. Brands include Dayquil, Sinex, Mucinex and Benadryl. The only other nasal decongestant approved by the FDA, pseudoephedrine, has become much more tightly regulated because it can be used to make methamphetamine. Products containing pseudoephedrine can only be purchased by going to a pharmacy counter and handing over a driver’s license, thanks to a 2005 law aimed at combatting illicit meth. As a result, phenylephrine products have outpaced pseudoephedrine as consumers’ cold remedy of choice, researchers said. Between 2012 and 2021, consumers bought 19.8 billion units of phenylephrine products, compared… read on > read on >
During Grief and Loss, Simple Steps Can Help You Cope
Filling the day with simple activities could be the key to improving mood and well-being after a person has suffered the loss of a loved one, a new study finds. These “uplifts” — activities that can improve a person’s mood — helped ease grief on a day-to-day basis, researchers reported recently in the journal Applied Psychology Health and Well-Being. “In other words, there are things we can do — which are accessible for most people — to improve our moods,” said researcher Shevaun Neupert, a professor of psychology at North Carolina State University. “And those things can help us most on days when we most need it.” Uplifts that can help a person manage their grief include: Completing a task. Getting enough sleep. Dining out. Visiting, phoning or writing a friend. Spending time with family. These uplifts helped just about everyone, regardless of their age or financial status, researchers found. “Uplifts were good for everyone, but there is some nuance in not only who is most impacted, but when the uplifts are most powerful,” Neupert says. “For example, we found that the positive effect of uplifts was more pronounced for people who had experienced traumatic loss, and especially so on days when they reported feeling older.” For this study, researchers worked with data from 440 U.S. adults ages 50 to 85, 356 of whom had… read on > read on >
CDC Investigating Illness Outbreak on Luxury Cruise Ship
The U.S. Centers for Disease Control and Prevention is investigating an outbreak of gastrointestinal illness aboard a luxury cruise ship that sailed out of San Francisco on Wednesday. More than 150 people on the Queen Victoria, operated by Cunard Cruise Lines, have reported episodes of diarrhea and vomiting since the ship first set sail in early January, the CDC said in its investigation notice. A total of 125 passengers and 25 crew have fallen ill during the course of the voyage. Carrying a total 1,800 passengers and 970 crew members, the ship is next expected to dock in Honolulu, Hawaii, on Monday. The cause of the outbreak remains unclear, the CDC said, but Cunard told the agency that the ship has isolated ill passengers and crew and stepped up cleaning and disinfection efforts. The reported cases are totals for the entire voyage, the CDC noted. “Cunard confirms that a small number of guests had reported symptoms of gastrointestinal illness on board Queen Victoria,” Cunard told NBC News. “They immediately activated their enhanced health and safety protocols to ensure the well-being of all guests and crew on board. Measures have been effective,” Cunard added. The ship first left Germany on Jan. 9 and then departed Florida on Jan. 22, according to ship tracker Cruise Mapper, the Associated Press reported. The cruise ends in Australia next month.… read on > read on >
Survey Shows Transgender, Nonbinary People Suffer Financial Strife, Stigma
Preliminary data from the largest survey examining the quality of life for transgender and nonbinary Americans show they suffer high levels of unemployment and harassment. In the early findings, released Wednesday, the National Center for Transgender Equality gathered responses on 600 questions from more than 92,000 transgender and nonbinary Americans, age 16 and up, from every state in the country. This latest survey, conducted in late 2022, drew more than three times as many respondents as there were in 2015, the last time the survey was conducted. “You don’t see data sets like this,” survey leader Sandy James said during a media briefing, the New York Times reported. “Tens of thousands of trans people knew that it was imperative that they make their voices heard.” What did they want Americans to hear? Many respondents reported daunting financial challenges. Eighteen percent said they were unemployed, much higher than the national rate, and one-third said they had experienced homelessness at some point in their lives. More than one-quarter reported not seeing a doctor when they needed to in the previous year because of cost. But financial problems were not their only burden to bear: Nearly a third said they had been verbally harassed in the previous year, while 3% said they were physically attacked in the last year because of their gender identity. Still, they also shared positive… read on > read on >
Viagra, Cialis May Help Reduce Alzheimer’s Risk
Could drugs that give a boost to men’s sexual performance help them stave off Alzheimer’s disease? That’s the main finding from a study suggesting that erectile dysfunction meds like Cialis, Levitra and Viagra might lower the odds for the memory-robbing illness. The study wasn’t designed to prove cause-and-effect, cautioned British researchers at University College London. “More research is needed to confirm these findings, learn more about the potential benefits and mechanisms of these drugs and look into the optimal dosage,” explained study co-author Ruth Brauer, a lecturer in pharmacoepidemiology and medication safety at the university. She also believes that, “a randomized, controlled trial with both male and female participants is warranted to determine whether these findings would apply to women as well.” The findings were published Feb. 7 in the journal Neurology. Erectile dysfunction medications work by dilating blood vessels and increasing blood flow. The new study involved almost 270,000 men, averaging 59 years of age, who had all been newly diagnosed with erectile dysfunction (ED). A little more than half of them were prescribed an ED drug. None of the men had any cognitive or memory issues when they entered the study. Over five years of follow-up, 1,119 of the men were diagnosed with Alzheimer’s disease. Bauer’s team reported that men who were taking an ED drug had an 18% lower odds of developing… read on > read on >
Cutting U.S. Homelessness by 25% Could Prevent 2,000 Opioid Deaths Each Year
Reducing homelessness by 25% could save nearly 2,000 lives lost each year to opioid overdoses, a new study estimates. It also could save 850 lives from alcohol poisoning and 540 from cocaine overdoses, researchers from the University of Georgia estimate. This is the first study to suggest that homelessness contributes to deaths from substance use, the researchers said. “One of the frustrations for people who study and recommend policy changes is that homelessness and the opioid crisis are persistent,” said researcher David Bradford, a professor with the University of Georgia’s School of Public and International Affairs. “Our study shows that there is a causal effect. Homelessness is making the opioid crisis worse.” For the study, researchers analyzed federal data kept on homeless people between 2007 and 2017, comparing it with death certificates with drug overdose or alcohol poisoning as the cause of death. Researchers found that even a small decrease in homelessness could save lives. For example, even a 10% decrease in homelessness could save more than 650 from death by opioid overdose, their results show. “That’s a lot of lives,” said researcher Felipe Lozano-Rojas, an assistant professor in the University of Georgia’s School of Public and International Affairs. “Deaths from opioids used to be a rare event, but it has become increasingly prevalent.” Evictions have skyrocketed in recent years, with the lifting of the… read on > read on >
