U.S. Health Secretary Robert F. Kennedy Jr. says he will tell the U.S. Centers for Disease Control and Prevention (CDC) to stop recommending fluoride in drinking water across the country. He also announced plans to form a special task force to focus on health risks of fluoride. Kennedy made the comments Monday during a media event with U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin in Salt Lake City.  Last month, Utah became the first state to ban fluoride in public drinking water supplies. The EPA said it is reviewing new science about the possible dangers of fluoride in water, The Associated Press reported. Kennedy can’t force communities to stop fluoridating water, but he can influence the CDC’s recommendations and work with the EPA to change the allowed limits. The CDC currently recommends 0.7 milligrams of fluoride per liter of water, while the EPA allows up to 4 milligrams. “I’m very, very proud of this state for being the first state to ban it, and I hope many more will,” Kennedy said, referring to Utah. Under its new law all water systems in the state must stop adding fluoride by May 7. Kennedy called fluoride a “dangerous neurotoxin” that may also be linked to arthritis, thyroid problems and bone fractures, according to The Associated Press. Some studies have found possible health risks at higher-than-recommended levels…  read on >  read on >

The U.S. government has shut down or paused several major anti-smoking efforts.  Public health leaders say the cuts could reverse decades of progress that have smoking rates in the country at all-time lows. Last week, the Department of Health and Human Services (HHS) made major cuts to tobacco control offices at the U.S. Centers for Disease Control and Prevention (CDC) and U.S. Food and Drug Administration (FDA). Dozens of workers were let go, including Brian King, the FDA’s top tobacco regulator. The CDC’s Office on Smoking and Health, which led work on smoking cessation and research into youth tobacco use, was also cut. Former CDC Director Dr. Tom Frieden, now president of the global health organization Resolve to Save Lives, called the decision a “gift to Big Tobacco.” “The only winner here is the tobacco industry and cancer cells,” Frieden told NBC News. One of the biggest casualties? The CDC’s popular “Tips From Former Smokers” ad campaign. The program, which began in 2012, features real people who suffered health damage from smoking. A study published recently in the journal Nicotine & Tobacco Research shows that the ads lead to a sharp rise in calls to quit lines each time they air. “We estimate the Tips campaign generated nearly 2.1 million additional calls to 1-800-QUIT-NOW during 2012-2023,” the researchers wrote. 1-800-QUIT-NOW, the national quit line, connects…  read on >  read on >

The Trump administration has decided not to expand Medicare and Medicaid coverage for popular obesity drugs, blocking a Biden administration initiative that could have helped millions of Americans access the medications. Catherine Howden, a spokeswoman for the Centers for Medicare and Medicaid Services (CMS), said that expanding coverage for these drugs “is not appropriate at this time,” though it “may consider future policy options” for them. The decision was included in a 438-page rule updating other parts of Medicare’s drug coverage. Currently, Medicare covers these drugs only for people with diabetes, or in rare cases, for those who are obese and also have major heart problems or sleep apnea, The New York Times reported. Former President Joe Biden’s plan would have expanded access to people who are obese but do not have other health problems.  Officials estimated that about 3.4 million more people might start using the medications if coverage were expanded. The drugs include Novo Nordisk’s Wegovy and Ozempic, and Eli Lilly’s Zepbound and Mounjaro. These medications have shown benefits beyond weight loss, such as lowering the risk of heart attacks and strokes. But cost was a major concern. The Congressional Budget Office estimated that expanding coverage would cost the federal government around $35 billion over 10 years, The Times said. Retail prices for the drugs range from $350 to $500 per month without…  read on >  read on >

Smoke from wildfires driving you mad? You’re not alone, a new study says. Short-term exposure to air choked with wildfire smoke increases people’s risk of mental health problems, according to findings published April 4 in JAMA Network Open. Hospital emergency rooms experience surges in patients with mental health conditions on days when smoke pollution is at its worst, researchers found. “Wildfire smoke isn’t just a respiratory issue — it affects mental health, too,” said corresponding author Dr. Kari Nadeau, chair of environmental health at the Harvard T.H. Chan School of Public Health. “Our study suggests that — in addition to the trauma a wildfire can induce — smoke itself may play a direct role in worsening mental health conditions like depression, anxiety, and mood disorders,” Nadeau added in a news release. For the study, researchers tracked levels of particle pollution caused by California wildfires that occurred between July and December 2020 — the state’s most severe wildfire season on record. They compared that data to ER visits for mental health problems, and found that exposure to wildfire smoke substantially increased the number. Specifically, a 10 microgram-per-cubic-meter increase in wildfire particle pollution was linked to more ER visits for: Any mental health condition, with an 8% increased risk. Depression, with a 15% increased risk. Other mood disorders, with a 29% increased risk. Anxiety, with a 6%…  read on >  read on >

Ozone air pollution increases the risk of asthma among preschoolers and kindergarteners, a new study says. Relatively small increases in ozone smog in a child’s first two years of life is associated with an increased risk of asthma and wheeze at 4 to 6 years of age, researchers reported April 2 in JAMA Network Open. However, ozone exposure didn’t increase risk of asthma at ages 8 and 9, results show. “It’s a puzzling finding,” said lead researcher Logan Dearborn, a doctoral student with the University of Washington Department of Environmental & Occupational Health Sciences. “It’s something we spent a long time trying to consider, and I don’t know if we ever came up with a satisfying answer.” “But these findings are important,” Dearborn added in a news release. “Even if we only see the effects early in life, there are still all kinds of associated health care costs and stresses for families.” For the study, researchers analyzed data on more than 1,100 children from a federal research project investigating how environmental factors can affect children’s health. The children lived in six cities – Minneapolis; San Francisco; Seattle; Memphis, Tenn.; Rochester, N.Y.; and Yakima, Wash. The team compared kids’ asthma and wheeze as reported by their moms to federal data on ozone pollution in their area. Previous studies have linked childhood asthma to exposure to fine…  read on >  read on >

Wondering what recovery is really like after knee replacement surgery?  Dr. Ayesha Abdeen, chief of hip and knee replacement surgery at Boston Medical Center, breaks down exactly what to expect — from managing pain in the first few days to getting back on your feet and returning to the activities you love. Total knee replacement (TKR) surgery is usually done using spinal anesthesia along with a nerve block to help reduce pain after surgery. Right after the procedure, you will likely still feel pain relief from the nerve blocks for about eight to 12 hours. Once the spinal anesthesia wears off — usually within the first hour or so in the recovery room — you will be encouraged to start walking.  Early movement helps speed up recovery and lowers the risk of serious blood clots that can form in your leg (deep vein thrombosis) and travel to your lungs (pulmonary embolism). You will also be given a medication to help prevent blood clots, such as aspirin or a stronger blood thinner (anticoagulant), depending on the type of clots you have. Pain during the first few days after TKR can be strong, especially in the front and back of the knee. Pain in the back of the knee may be due to bone spurs caused by arthritis that are removed during the surgery. To help manage…  read on >  read on >

Common chemicals used in plastic and personal care products may interfere with brain development in babies, a new study says. Phthalates are found in many everyday items, like food packaging, shampoo, toys and vinyl flooring. They help make plastics soft and carry scents in products. But they may also harm unborn babies’ brains when mothers are exposed during pregnancy, researchers say. “We conducted this study because phthalates are everywhere in our daily lives,” senior study author Donghai Liang, an associate professor of environmental health at Emory University’s Rollins School of Public Health in Atlanta, told to CNN. Hence their nickname “everywhere chemicals.” His team found that babies who had been exposed to these chemicals in the womb had lower levels of important brain chemicals, including serotonin and dopamine.  These help control mood, learning and a baby’s reactions. The study, published April 2 in the journal Nature Communications, followed 216 mother-baby pairs in Atlanta. Researchers tested urine from pregnant women for phthalates and tested the babies’ blood after they were born. The tests revealed that babies exposed to phthalates had low levels of tyrosine and tryptophan — amino acids that help make key brain chemicals. These babies also scored lower on tests of attention and response. Phthalates have been linked to many health issues, including asthma, obesity and even cancer. This new research helps explain how…  read on >  read on >

The U.S. Food and Drug Administration (FDA) has delayed the full approval of Novavax’s COVID-19 vaccine.  The decision had been expected by April 1, but the agency now says it needs more information before moving forward. The Novavax shot is already available under emergency use. But full FDA approval would allow the vaccine to be used more widely and could offer more reassurance to people looking for options besides the existing mRNA vaccines, CNN reported. The delay dovetails with moves by Republican lawmakers in at least seven states to ban or limit mRNA vaccines. Some, according to KFF Health News, are also pressing regulators to revoke federal approval for mRNA-based COVID shots, which President Donald Trump has touted as a key first- term achievement.  Novavax uses protein-based technology, a more traditional method than the mRNA vaccines from Pfizer and Moderna.  “As of Tuesday, April 1, we had responded to all of the FDA’s information requests and we believe that our [Biologics License Application] is ready for approval,” Novavax said in a statement, adding that its application “included robust Phase 3 clinical trial data that showed our vaccine is safe and effective for the prevention of COVID-19.” “We are confident our well-tolerated vaccine represents an important alternative to mRNA COVID-19 vaccines for the U.S.,” Novavax added. The delay comes as the FDA is undergoing leadership changes.…  read on >  read on >

Antidepressants appear to increase people’s risk of sudden cardiac death, a new study says. People taking the mood meds are more likely to die suddenly from heart problems, and their risk rises the longer they’re on the drugs, according to findings presented Monday in Vienna at a meeting of the European Society of Cardiology. “Exposure time to antidepressants was associated with a higher risk of sudden cardiac death, and linked to how long the person had been exposed to antidepressants,” said lead researcher Jasmin Mujkanovic of Rigshospitalet Heart Center in Copenhagen. “Those exposed for six years or more were at even more increased risk than those exposed for one to five years, when compared with people unexposed to antidepressants in the general population,” Mujkanovic said in a news release. For the new study, researchers examined all deaths among adults in Denmark in 2010, looking for people taking andepressants and people who suffered sudden cardiac death. Sudden cardiac death involves a person’s heart unexpectedly stopping due to some heart-related problem, researchers said in background notes. Younger adults usually suffer sudden cardiac death due to heart disease or an electrical problem with the heart, while older people most often fall prey due to clogged arteries, researchers said. Overall, people who’d been taking antidepressants for one to five years had a 56% increased risk of sudden cardiac death,…  read on >  read on >

Disrespected by a neighbor or colleague? Eyerolls from servers at a restaurant or store? Denied a job or a mortgage due to skin color? More than half of Americans have experienced some such form of discrimination, and this mistreatment dramatically increases their risk of depression or anxiety, a new study says. Nearly 56% of Americans have encountered discrimination in their lives, and almost 4% said they’d experienced high levels of discrimination, according to findings published March 28 in JAMA Network Open. Those exposed to high levels of discrimination are five times more likely to be diagnosed with depression or anxiety, and nearly nine times more likely to screen positive for both mood disorders, results show. “Everyday discrimination is a widespread issue that negatively impacts mental health across all racial and ethnic groups,” lead researcher Monica Wang, an associate professor of community health services at Boston University School of Public Health, said in a news release. For the study, researchers analyzed 2023 federal survey data to gauge experiences of discrimination, depression and anxiety among nearly 30,000 U.S. adults. Discrimination was scored based on answers to questions like: “How often are you treated with less courtesy or respect than others?” “How often do you receive poorer service at restaurants or stores compared to others?” “How often do people act as if they think you are not smart?”…  read on >  read on >
