Dirty Air Might Harm Your Kidneys

Posted 21 Sep 2017 by Drugs.com

THURSDAY, Sept. 21, 2017 – Air pollution may harm your kidneys, a new study says. "Even levels below the limit set by the [Environmental Protection Agency] were harmful to the kidneys. This suggests that there is no safe level of air pollution," said study leader Dr. Ziyad Al-Aly. Al-Aly is director of clinical epidemiology at the VA Saint Louis Health Care System. He and his colleagues analyzed data from nearly 2.5 million U.S. military veterans who were followed for roughly 8.5 years. They found that as exposure to particulate matter air pollution increased, so did the risk of poorer kidney function, kidney disease and kidney failure. Particle pollution refers to a complex mix of extremely small particles, such as soot, dirt and smoke, and liquid droplets found in the air, according to the U.S. Environmental Protection Agency. It's already known that inhaling these particles can ... Read more

Kids' Colds Linked to Asthma, Lung Problems Later

Posted 19 Sep 2017 by Drugs.com

TUESDAY, Sept. 19, 2017 – Kids who develop respiratory infections like colds or sinusitis may have a higher risk of asthma and reduced lung function later in life, a new study says. Researchers examined data from nearly 155,000 children in Europe. They were followed from birth through ages 4 to 15 years. Those who had an upper respiratory infection – such as a cold, sinusitis, laryngitis and tonsillitis – by age 5 had an increased risk of asthma later in life. Their risk was 1.5 times higher. Young children who had lower respiratory tract infections such as bronchitis, bronchiolitis, pneumonia and general chest infections saw their asthma risk double or quadruple. They were also more likely to later develop reduced lung function, according to the study. "These findings support the hypothesis that early life respiratory tract infections may influence the development of respiratory ... Read more

Minorities Exposed to Dirtier Air, U.S. Study Finds

Posted 18 Sep 2017 by Drugs.com

MONDAY, Sept. 18, 2017 – Nonwhite Americans are surrounded by more air pollution from traffic than whites are, a new study finds. While exposure to nitrogen dioxide (NO2) fell among all Americans between 2000 and 2010, there was only a slight narrowing in differences between levels of exposure to the pollutant between nonwhites and whites. "The finding that shocks us is that when it comes to how much NO2 a person breathes, it's still race that matters," said senior study author Julian Marshall. He is professor of civil and environmental engineering at the University of Washington in Seattle. "At any income level – low to medium to high – there's a persistent gap by race, which is completely indefensible. It says a lot about how segregated neighborhoods still are and how things are segregated," he explained in a university news release. The estimated average annual NO2 exposure fell ... Read more

Nearly 4 Million Worldwide Die Each Year From Asthma, COPD

Posted 17 Aug 2017 by Drugs.com

WEDNESDAY, Aug. 16, 2017 – Two major chronic lung diseases – asthma and COPD – kill nearly 4 million people worldwide annually, a new report finds. The study calculates that 3.2 million people died in 2015 from COPD (chronic obstructive pulmonary disease) – a group of lung conditions that includes emphysema and chronic bronchitis, often tied to smoking. Asthma caused another 400,000 deaths, the report found. While asthma is more common, COPD is much more deadly. And while both conditions can be treated, many people remain undiagnosed or misdiagnosed. In addition, in many countries, treatment – if it exists at all – may be at insufficient levels, the research team added. "Although much of the burden [from these illnesses] is either preventable or treatable with affordable interventions, these diseases have received less attention than other prominent non-communicable diseases like ...

Air Purifiers May Help the Smog-Stressed Heart

Posted 14 Aug 2017 by Drugs.com

MONDAY, Aug. 14, 2017 – High levels of air pollution can harm heart health, but air purifiers may protect against the threat, according to a small study from China. The study included 55 healthy college students who used real or fake air purifiers in their dormitory rooms. Researchers measured the students' indoor and outdoor exposure to fine particulate matter (PM2.5), a component of air pollution emitted from vehicles, factories, power plants, fires and smoking. Exposure to high PM2.5 levels increased students' stress hormones and triggered metabolic changes that may increase heart disease risk, the researchers said. Using air purifiers reduced indoor levels of PM2.5 by an average 82 percent and led to short-term declines in stress hormone levels. After 24 hours of air purifier use, PM2.5 levels were within the World Health Organization's safe range, the study found. The findings ... Read more

Rush Hour Pollution May Be Worse Than Thought

Posted 28 Jul 2017 by Drugs.com

FRIDAY, July 28, 2017 – Ever wonder what you're inhaling as you idle in rush-hour traffic? New research finds air pollution levels in cars are much higher than previously believed. "We found that people are likely getting a double whammy of exposure in terms of health during rush-hour commutes," said Michael Bergin, a professor of civil and environmental engineering at Duke University, in Durham, N.C. He and his colleagues installed sensors inside about 30 cars going to and from downtown Atlanta. Over the 60 commutes, they found that levels of some types of harmful particulate air pollution in the cars were twice as high as levels detected by widely used roadside sensors. "If these chemicals are as bad for people as many researchers believe, then commuters should seriously be rethinking their driving habits," Bergin added in a university news release. The contaminated air particles can ... Read more

Health Tip: When Air Quality is Poor

Posted 10 Jul 2017 by Drugs.com

-- Poor air quality is a serious issue for people with breathing problems, such as asthma. When air quality is poor, the National Weather Service suggests: If you're exercising outdoors, make your routine less strenuous than usual Take more frequent breaks. And shorten the length of your workout. Move planned outdoor activities to another day or indoors. If that's not possible, schedule activities in the morning, when air quality generally is better.

Even at Low Levels, Dirty Air Raises Death Risk for U.S. Seniors

Posted 28 Jun 2017 by Drugs.com

WEDNESDAY, June 28, 2017 – Air pollution may shorten the lives of American seniors, even in areas where levels fall below national safety standards, new research indicates. Although it's possible that factors other than air pollution are responsible for the increase in premature deaths among older adults, study co-author Francesca Dominici said the findings are "bulletproof evidence of increased risk of deaths due to polluted air in the U.S. "Make no mistake. We need to strengthen, not weaken, [U.S. Environmental Protection Agency] air pollution standards," said Dominici, a professor of biostatistics at Harvard T.H. Chan School of Public Health in Boston. "We need to increase, not reduce, the EPA research funding." The investigators launched their research to determine whether pollution levels considered to be acceptable might still be hazardous to human health. "There is extensive ... Read more

City Tax on Cars Cut Pollution, Kids' Asthma Risk

Posted 7 Mar 2017 by Drugs.com

TUESDAY, March 7, 2017 – A tax designed to reduce mid-city traffic in Stockholm, Sweden, was tied to a reduction in asthma attacks in children, a new study suggests. "The key takeaways of this paper are that health gains can be realized through efforts to lower air pollution, and that we need to be patient in waiting for the complete picture to emerge," said study author Emilia Simeonova, an assistant professor at Johns Hopkins University in Baltimore. After Stockholm introduced the "congestion tax" as an experiment in 2006 to discourage people from driving in the center of the city, traffic flow got better and air pollution levels fell by 5 to 10 percent. The tax was made into law in 2007. The tax costs drivers the U.S. equivalent of $2.60 when they drive in certain areas of the city at congested times of the workday. The tax is collected through scanners that gather license plate ... Read more

Can Mom's Vitamin E Head Off Child's Asthma Risk?

Posted 5 Mar 2017 by Drugs.com

SATURDAY, March 4, 2017 – Kids born to moms with low levels of vitamin E might be more likely to develop asthma, new research suggests. When moms had low levels of a specific type of vitamin E measured right after birth, their children were more likely to develop wheezing and to have been treated with asthma medications in their first two years of life, the study found. "The major sources of vitamin E are oils" such as sunflower, safflower, corn, soy and canola oils, study lead author Dr. Cosby Stone said in a news release from the American Academy of Allergy, Asthma & Immunology (AAAAI). Stone said his team's previous research in mice had suggested the link between vitamin E and asthma. Stone is with Vanderbilt University Medical Center in Nashville. "We hypothesized that maternal vitamin E levels, reflecting levels that the fetus encounters during pregnancy," would affect how kids ... Read more

Flu Shot May Curb Respiratory Infections in People With Heart Failure

Posted 2 Feb 2017 by Drugs.com

THURSDAY, Feb. 2, 2017 – Flu and pneumonia vaccines may reduce heart failure patients' risk of dangerous respiratory infections, a new review suggests. More than 5 million Americans have heart failure, when the heart is too weak to pump enough blood to meet the body's needs. Respiratory infections are the leading cause of hospitalization for people with heart failure. These infections are associated with high death rates in a hospital, the review authors said. The researchers reviewed studies published from January 1990 to July 2016. These studies suggested that flu and pneumonia vaccines seem to help protect people with heart failure from life-threatening respiratory infections. People older than 65 with heart failure may benefit more from high-dose vaccination, the researchers said. "Vaccination represents a low-cost intervention that may be able to prevent the significant disease, ... Read more

Can Air Pollution Heighten Alzheimer's Risk?

Posted 1 Feb 2017 by Drugs.com

WEDNESDAY, Feb. 1, 2017 – Air pollution may cause more than just lung disease: New research suggests that if tiny particles in the air from power plants and cars are inhaled, they might also invade the brain, increasing the risk for dementia. "Although the link between air pollution and Alzheimer's disease is a new scientific frontier, we now have evidence that air pollution, like tobacco, is dangerous to the aging brain," said study co-senior author Caleb Finch. He's with the University of Southern California's (USC) Leonard Davis School of Gerontology. For the study, the USC scientists collected samples of air particles with technology designed by university engineers. The researchers used the technology to expose female mice to air pollution. "Our state-of-the-art aerosol technologies, called particle concentrators, essentially take the air of a typical urban area and convert it to ... Read more

How to Spot a Common, Potentially Dangerous, Childhood Illness

Posted 12 Jan 2017 by Drugs.com

WEDNESDAY, Jan. 11, 2017 – Nearly all children get respiratory syncytial virus (RSV) by age 2. But just because the infection is common doesn't mean it should be taken lightly, one nursing specialist warns. Symptoms of this lung and respiratory infection – coughing, sneezing and a runny nose – are often mistaken for a cold, according to Alison Pittman, clinical assistant professor at Texas A&M College of Nursing. "Most healthy children will experience cold-like symptoms, but it can easily spread to babies with pre-existing conditions," and put them at risk for serious health problems, she said in a college news release. Those at greatest risk for a severe infection include premature babies, children born with heart or lung problems, and people of any age who have weakened immune systems. Most babies with RSV develop a cough, runny nose and other cold-like symptoms for one to two ... Read more
