Peak asthma month is upon parents as summer draws to a close, experts warn. “September is known as Asthma Peak Month because kids have returned to school, and viruses are being passed around,” said allergist Dr. Gailen Marshall, president of the American College of Allergy, Asthma and Immunology. “September also sees higher levels of environmental allergens like mold and ragweed. In addition, children may have stopped their regular asthma management routine over the summer,” Marshall added in a ACAAI news release. “Generally, allergists see an increase in patients in September — more asthma attacks and more hospitalizations — especially in children.” But there are ways parents can help their kids keep their allergy and asthma symptoms at bay as the school year resumes, Marshall said. Find an allergist. A pre-school appointment with a board-certified allergist can arm parents with an allergy or asthma action plan that identifies triggers and prepares prescriptions. Asthmatic kids under the care of an allergist have a 77% reduction in lost time from school, Marshall said. Teamwork helps. It’s important to work with a child’s teacher regarding their allergies and asthma, Marshall said. Most teachers have experience helping kids with asthma. Parents should be sure to share their child’s treatment plan with school staff, including their asthma triggers and any treatments or medications they use. Avoid viruses.

An additional cinnamon product sold in the United States has been found to contain high levels of lead, health officials are warning. In a health alert issued Thursday, the U.S. Food and Drug Administration said the ground cinnamon product, sold as El Servidor, joins a growing list of cinnamon products that have contained high levels of lead. Through testing, the cinnamon was found to have elevated lead levels at 20 parts per million. Although the FDA doesn’t set limits for lead levels in spices, the United Nations’ Food and Agriculture Organization has a proposed international safety standard of 2.5 parts per million of lead for bark spices like cinnamon, NBC News reported. The FDA noted that it has asked the distributor to recall the product. Lead in cinnamon products has become a growing problem: In March, the FDA warned about lead in fruit puree products sold at Dollar Tree, Family Dollar and other stores. Those products had levels of lead ranging from 2.03 to 3.4 parts per million. The cinnamon identified in the new alert was sold at a supermarket in New York City, although it’s unclear whether it was distributed more widely. Leigh Frame, director of integrative medicine at George Washington University School of Medicine and Health Sciences, told NBC News that the new recall was “alarming.” “We sort of assume things are safe until proven otherwise,” Frame… read on > read on >

Bad news for Olympians headed to Paris — high levels of ozone pollution and grass pollen are likely during the upcoming games if hot, sunny weather prevails, researchers said. Ozone levels in Paris and its environs tend to exceed World Health Organization (WHO) recommended thresholds about 20 days per month between July and September, according to an analysis of air quality monitoring data from recent years. “Air quality in Paris during the summer can be characterized mainly by high ozone levels in the afternoon, especially on sunny and hot days,” concluded the research team led by Valerie Bougault, an associate professor with the University Cote d’Azur in Nice, France. Highly allergenic grass pollen will also be filling the air, although researchers noted those levels tend to fall between July and September. Researchers said they undertook the study to help Olympic athletes and spectators best prepare for the games. “By comparing these [air quality] levels with those in their area, athletes and spectators can see if they need to take steps to avoid or reduce their exposure,” the researchers wrote. “They can discuss this with their doctor and plan their activities to avoid the times and types of places where pollution is highest.” For the study, researchers analyzed air pollution readings from Paris and its suburbs taken between 2020 and 2023, as well as pollen counts… read on > read on >

Americans’ risk of dying in a firearm accident depends in large part on where they live in the United States, a new study finds. People in Southeastern states like Mississippi, Louisiana and Alabama run the greatest risk of a gunshot accidentally killing them, researchers said. Meanwhile, the risk of accidental gun death is much lower in Northeastern states like Massachusetts, New York, Maryland and Connecticut, results show. “Crude rates in the states with the highest rates, clustered mostly in the Southeast, were about 10 times the rates in the states with the lowest rates, located mostly in the Northeast,” concluded researcher David Schwebel, a professor of psychology with the University of Alabama at Birmingham. Nationwide, more than 12,300 people died in gun accidents between 2001 and 2021, Schwebel found in his analysis of firearms deaths data maintained by the U.S. Centers for Disease Control and Prevention. The researchers also found that specific factors within a state increased the risk of death in a firearms accident. Unsurprisingly, states with more gun owners carried a higher risk of accidental gun death. But the study, published July 25 in the journal Injury Prevention, also found that having a higher percentage of families living below the poverty line is associated with an increased risk of accidental death. Any solution to this risk is not going to be easy, Schwebel… read on > read on >

People diagnosed with one of the most common inherited heart arrhythmias, called Long QT syndrome (LQTS), can safely engage in vigorous exercise without any added risk for sudden death or cardiac arrest, a new study finds. “Arrhythmic events were low in these appropriately treated individuals with LQTS in both those exercising vigorously and those exercising moderately or who were sedentary,” concluded a team led by Dr. Rachel Lampert, a professor of cardiology at Yale University School of Medicine. According to the Cleveland Clinic, LQTS involves delays in “recharging” the heart’s electrical system, which in turn can lead to a potentially dangerous irregular heartbeat. Medications, implanted devices and surgery are used to help control the condition, which is often inherited. According to one European study, LQTS occurs in about 1 in every 2,500 people, making it “the most commonly detected genetic electrical abnormality” of the heart, Lampert’s team said. Prior studies had suggested that vigorous exercise might help trigger cardiac arrest in people with LQTS, but as the researchers pointed out, those studies largely involved patients whose LQTS was only diagnosed after such a heart event. What about people who already know they have LQTS and are being appropriately treated? To find out, her team tracked outcomes over three years for 1,413 people diagnosed with LQTS at 37 medical sites in five countries. These people ranged… read on > read on >

Wildfires raging in several states and Canada are triggering air quality alerts and evacuation orders across the western parts of the United States. Smoke and haze have filled the skies in California, Oregon, Arizona, Washington and several other western states: As of Wednesday, there were 79 large, active wildfires that have burned over 1.4 million acres across the country, according to the National Interagency Fire Center. Evacuation orders are in effect for 15 fires in the Northwest, the Associated Press reported. Meanwhile, Canada is battling about 430 active wildfires in British Columbia and 177 in neighboring Alberta, including two that led to the evacuation of up to 25,000 visitors and residents of the Canadian Rockies’ largest national park, the AP reported. To deal with the pollution spewing from these wildfires, air quality alerts and advisories have been issued in many parts of the western United States: The Oregon Department of Environmental Quality issued air quality alerts for the eastern counties of Harney, Malheur, Grant, Baker and Morrow until further notice. In Idaho, air quality advisories were sent out to the central counties of Ada, Canyon, Gem, Owyhee, Payette and Washington. In north central Washington, the Colville Reservation, all of Chelan County, plus the Methow Valley down to Brewster in Okanogan County were under air quality alerts until further notice. Last but not least, Canadian authorities issued an air quality advisory for… read on > read on >

The Olympics are often described as a rare, once-in-a-lifetime shot at international sports glory. That may be more true for Olympic track and field competitors than other athletes, a new study reports. There appears to be a peak performance age for track and field athletes, who specialize in running, jumping and throwing events, researchers report. It turns out that the peak age for these athletes is 27. After age 27, there’s only a 44% chance that an athlete’s peak is still ahead of them, results show. That number drops every subsequent year. What’s more, the average age of Olympic track and field athlete has remained remarkably consistent over the past three decades — just under 27. “Because the Olympics occur only once every four years, track and field athletes must carefully consider when and how they should train to maximize their probability of qualifying for the Olympics while at their personal peak,” said lead researcher David Awosoga, a master’s student in data science at the University of Waterloo in Canada. For the study, researchers analyzed year-by-year career performance data from every track and field athlete at the Olympics since the 1996 games in Atlanta. The team considered each athlete’s gender, nationality, event type and training level. Researchers focused on track and field because for many of these athletes, the Olympics offers the best chance to… read on > read on >

Finding yourself packing on the pounds around your waist and arms? If so, you might be at heightened risk for neurological illnesses like Alzheimer’s or Parkinson’s, new research suggests. There was one other physical characteristic that lowered the odds, however: muscle strength. Stronger folk appeared to have a lower odds for neurological illnesses compared to weaker people, reported a team of Chinese researchers. “This study highlights the potential to lessen people’s risk of developing these diseases by improving their body composition,” said study lead author Dr. Huan Song, of Sichuan University in Chengdu. “Targeted interventions to reduce trunk and arm fat while promoting healthy muscle development may be more effective for protection against these diseases than general weight control,” she added. The findings were published July 24 in the journal Neurology. Over a nine-year span, the researchers tracked the health and body characteristics of almost 413,000 British people who averaged 56 years of age when they entered the study. Song’s group measured each person’s waist and hip, tested their hand-grip strength, their bone density and their fat and lean mass. Over the nine years, 8,224 people did go on to develop neurodegenerative diseases, typically Alzheimer’s disease, other forms of dementia or Parkinson’s. After adjusting for other health risk factors that can affect the brain — things like high blood pressure, smoking, drinking and diabetes… read on > read on >

Obese kids infected with dengue are significantly more likely to suffer severe illness requiring hospitalization, a new study warns. A new analysis of nearly 5,000 dengue-infected Sri Lankan children found that weight plays a powerful role in how sick the mosquito-borne virus can make a kid. Kids with higher BMIs had higher hospitalization rates than those children who weighed less, researchers reported recently in the journal PLOS Neglected Tropical Diseases. The heaviest children — those who are clinically obese — were twice as likely to be hospitalized as the rest, results show. “With the increase in obesity in many countries, it would be important to create awareness and educate the public of the potential risks regarding obesity and risk of severe disease and hospitalization from dengue,” said senior researcher Dr. Neelika Malavige, a professor of immunology and molecular medicine at the University of Sri Jayewardenepura in Sri Lanka. The study comes weeks after health officials in the Florida Keys issued a dengue alert following two confirmed cases of the infectious disease there, and the U.S. Centers for Disease Control and Prevention has issued a nationwide advisory about an increased risk of dengue infections in the U.S. Dengue reached a historic high of more than 6.5 million cases and more than 7,300 deaths worldwide in 2023, researchers said in background notes. And the world is about… read on > read on >

Millions of Americans deal with the sleep deficits brought on by sleep apnea, and many turn to one of the few treatments out there, continuous positive airway pressure (CPAP) machines. But what if new neurochemical targets in the brain could lead to new, less cumbersome therapies for sleep apnea? That’s what a team at the University of Missouri-Columbia are working on in their lab. They’ve pinpointed specific brain chemicals in mouse brains that link sleep apnea to one of its most unhealthy side effects, high blood pressure. “Our ultimate goal is to eventually help clinicians develop specific drugs to target either these neurochemicals or the proteins they bind to in a way that reduces high blood pressure,” explained senior study author David Kline, an investigator at the university’s Dalton Cardiovascular Research Center. The study, which was led by postdoctoral researcher Procopio Gama de Barcellos Filho, involved mice whose brains were subjected to a low-oxygen state similar to what humans experience when they periodically stop breathing due to sleep apnea. Examining the rodents’ neurochemistry, Filho and Kline noticed key changes when in this “hypoxic” state. “When oxygen levels in the blood drop during sleep apnea, the forebrain sends warning signals to the brainstem area that controls heart and lung functions,” Kline explained. “By studying these signals, we found that two neurochemicals, oxytocin and corticotropin-releasing hormone (CRH),… read on > read on >
