1 in 3 Adults Diagnosed With Asthma May Not Have It: Study

Posted 2 days 18 hours ago by Drugs.com

TUESDAY, Jan. 17, 2017 – Many adults who've been diagnosed with asthma may not actually have the respiratory disease, a new study suggests. Researchers in Canada said that of more than 600 adults diagnosed with asthma, one-third did not have the disease based on objective tests. Eighty percent of those people had been taking asthma drugs. That included 35 percent who were taking medication every day, the investigators found. Respiratory experts said the findings are worrying, considering the cost and side effects of asthma drugs. And it's not completely clear why so many patients with an asthma diagnosis did not really have the disease. There were some cases where people obviously had asthma when they were diagnosed, said lead researcher Dr. Shawn Aaron, a respiratory specialist at Ottawa Hospital, in Canada. But their symptoms later went into remission. In most cases, though, it could ... Read more

Airway Differences May Explain Why Asthma Can Be More Serious for Blacks

Posted 7 days ago by Drugs.com

FRIDAY, Jan. 13, 2017 – Differences in airway inflammation may be one reason why black people with asthma are less responsive to treatment and more likely to die from the disease than white people, a new study suggests. Asthma is a chronic lung disease, and airway inflammation is a major component of asthma. The inflammation causes the airways to swell and become more sensitive, which eventually leads to symptoms such as wheezing and shortness of breath, according to the U.S. National Heart, Lung, and Blood Institute. "Emerging evidence suggests that differences in airway inflammation can affect a patient's response to treatment, but whether the patterns of airway inflammation vary across race has, until now, been very unclear," said study corresponding author Dr. Sharmilee Nyenhuis. She's an allergy, asthma and immunology specialist at University of Illinois at Chicago. Blacks are two ... Read more

Are Heartburn Meds During Pregnancy Linked to Asthma in Kids?

Posted 11 days ago by Drugs.com

MONDAY, Jan. 9, 2017 – Women who take certain heartburn medications during pregnancy may have a child at increased risk of developing asthma, new research suggests. For the new study, investigators analyzed eight studies that included more than 1.3 million children. The researchers found that kids born to mothers who were prescribed drugs for acid reflux during pregnancy were at least one-third more likely to have been seen by a doctor for asthma symptoms. Some of the medications come from drug classes that include Tagamet, Zantac, Prilosec, Nexium and Pepcid. "Our study reports an association between the onset of asthma in children and their mothers' use of acid-suppressing medication during pregnancy," said researcher Dr. Aziz Sheikh. He's co-director of the Asthma UK Center for Applied Research, at the University of Edinburgh in Scotland. "It is important to stress that this ... Read more

Kids' Asthma Flareups Fall Off After No-Smoking Laws

Posted 11 days ago by Drugs.com

MONDAY, Jan. 9, 2017 – In many U.S. communities that have adopted indoor smoking bans, fewer children need emergency asthma treatment, a new study finds. ER visits for childhood asthma attacks fell 17 percent overall in 20 metropolitan areas that prohibit smoking in public places such as restaurants and hotels, researchers found. The study doesn't confirm that the clean air laws directly boost lung health in kids. But, it makes a strong case, according to the researchers from Brown University, the University of Chicago Medical Center and Kansas University. "Combined with other studies, our results make it clear that clean indoor air legislation improves public health," study co-author Theresa Shireman said in a University of Chicago news release. She's a professor at the Brown School of Public Health. Study author Dr. Christina Ciaccio agreed. "Children are in a very unique situation ... Read more

Many Poor Asthma Sufferers Stuck in Settings That Make Their Disease Worse

Posted 16 days ago by Drugs.com

WEDNESDAY, Jan. 4, 2017 – Poor Americans with asthma face constant challenges in managing their respiratory disease – from dilapidated housing to neighborhood violence to depression, new research shows. The study offers a snapshot of the lives of asthma patients living in inner-city Philadelphia, from the point of view of community health workers who visited them at home. It's a bleak picture, and asthma experts called it "eye-opening." The home visits revealed that most patients were unemployed and often lived in overcrowded homes in a state of disrepair: Major water leaks, mold, rodents and cockroaches – all potential asthma triggers – were common. People were also frequently dealing with multiple medical conditions, such as diabetes and high blood pressure. And then there was the stress of daily living. Many faced neighborhood violence, had no transportation or lacked family and ... Read more

Fish Oil During Pregnancy May Cut Kids' Asthma Risk

Posted 29 Dec 2016 by Drugs.com

THURSDAY, Dec. 29, 2016 – Women who take fish oil during their third trimester of pregnancy might cut their children's risk of developing asthma by as much as one-third, a new clinical trial suggests. The fish oil dose was high – with fatty acid levels that were 15 to 20 times more than the average American gets from food. But there were no significant side effects, according to lead researcher Dr. Hans Bisgaard. He's a professor of pediatrics at the University of Copenhagen, in Denmark. He stopped short of making any general recommendations for pregnant women, however. Bisgaard said his "personal interpretation" is that fish oil offers a safe way to prevent some cases of childhood asthma. But he also said there are questions left for future studies. Among them are: What is the best point in pregnancy to start fish oil, and what is the optimal dose? Experts who were not involved in ... Read more

Cured Meats Could Aggravate Asthma, Study Suggests

Posted 21 Dec 2016 by Drugs.com

TUESDAY, Dec. 20, 2016 – Regularly eating cured meats such as ham and salami might aggravate asthma, researchers report. Looking at close to 1,000 people with the respiratory disease, French researchers found that those who ate the most processed and cured meats were 76 percent more likely to see their asthma symptoms worsen over time compared to those who ate the least. These symptoms include trouble breathing, chest tightness and shortness of breath, according to the report. Cured meats are high in chemicals called nitrites to keep them from spoiling. These meats have been linked to a higher risk of other chronic diseases, including cancer, heart disease, type 2 diabetes and chronic obstructive pulmonary disease (COPD). In addition, they were recently classified as carcinogenic, or cancer-causing, by the World Health Organization (WHO), said the study's lead researcher, Dr. Zhen Li. ... Read more

Study Sees Link Between Insomnia, Asthma

Posted 9 Dec 2016 by Drugs.com

FRIDAY, Dec. 9, 2016 – Insomnia is common in adults with asthma and tied to worse asthma control and other health problems, a new study finds. University of Pittsburgh researchers found that 37 percent of adults with asthma also had significant insomnia. Those with insomnia had worse lung function. They also weighed more. And they tended to have lower incomes than those without insomnia, the study found. Insomnia was also linked to a reduced asthma-specific quality of life. People with asthma and trouble sleeping had more depression and anxiety symptoms, the study found. They also needed more asthma-related health care in the past year. The study was published in the journal Chest. Although the study wasn't designed to prove a cause-and-effect relationship, the researchers suggested that their findings show that insomnia affects people with asthma. They also said that evaluation and ... Read more

Mice May Be Key to Kids' Asthma Attacks at School

Posted 2 Dec 2016 by Drugs.com

FRIDAY, Dec. 2, 2016 – Research investigating schoolchildren's asthma attacks has pointed to a tiny foe: mice. Allergens from the rodents can infiltrate the air, the study found, and may be a major cause of asthma attacks in the school environment. It's known that many different allergy triggers – from dust mites to mold to pet dander – can fuel children's asthma symptoms. But most research has focused on the triggers in kids' homes. "In this study, we've identified the school as an important factor, too," said researcher Dr. Wanda Phipatanakul, an allergy specialist at Boston Children's Hospital. That said, she stressed, the findings do not actually prove that schools' rodent problems were the cause of kids' symptoms. The next step, Phipatanakul said, is a study where schools will get air purifiers and "integrated pest management," to see if that improves students' respiratory ... Read more

Many Women With Chronic Ills Don't Use Online Tools

Posted 28 Nov 2016 by Drugs.com

MONDAY, Nov. 28, 2016 – Chronically ill women who don't use the internet may struggle with worse health, a new study finds. "A significantly larger proportion of non-internet users reported needing help learning what to do to manage their health conditions and needing help learning how to care for their health conditions," said researcher Carolyn Mendez-Luck. She's an assistant professor in the School of Social and Behavioral Health Sciences at Oregon State University. She and her colleagues analyzed information provided by hundreds of American women aged 44 and older with at least one chronic condition. These included heart disease, cancer, stroke, diabetes, arthritis, asthma, emphysema and anxiety. More than one-third didn't use the internet. And fewer than half of those who did have access used the web to learn from others with a chronic disease, the researchers found. Also, fewer ... Read more

Food Allergies Among Kids Vary by Race: Study

Posted 22 Nov 2016 by Drugs.com

TUESDAY, Nov. 22, 2016 – Black and Hispanic children are much more likely to have corn, shellfish and fish allergies than white children, according to a U.S. study. The study also found that compared to whites, black children have much higher rates of asthma, eczema and allergies to wheat and soy. The results, from the study of 817 children who were diagnosed with food allergies from birth to age 18, show that race and ethnicity are important factors in how people are affected by food allergies, according to the researchers. "Food allergy is a prevalent condition in the U.S., but little is known about its characteristics and severity in racial minority groups," said study lead author Dr. Mahboobeh Mahdavinia, an allergy and immunology expert at Rush University in Chicago. "Our goal was to characterize the food allergy-related outcomes in these children and to identify any disparities ... Read more

How to Exercise Safely in Smog

Posted 11 Nov 2016 by Drugs.com

FRIDAY, Nov. 11, 2016 – Scientists say they have figured out the ideal speeds for cyclists and pedestrians to move in order to limit their inhalation of air pollution and still get the full benefits of exercise. "The faster you move, the harder you breathe and the more pollution you could potentially inhale, but you also are exposed to traffic for a shorter period of time. This analysis shows where the sweet spot is," study author Alex Bigazzi, a transportation expert at the University of British Columbia, said in a school news release. The researchers used a computer model of 10,000 people. The investigators found that cyclists should ride between 7.5 to 12.4 miles per hour on city roads. And, pedestrians should walk between 1.2 and 3.7 miles per hour. There are different recommended speeds depending on gender, age and road grades. For example, on flat roads the ideal speeds are: 7.8 ... Read more

Downside to Exercise for City Kids: More Pollution

Posted 3 Nov 2016 by Drugs.com

WEDNESDAY, Nov. 2, 2016 – Exercise is usually great for children, but a new study finds that city kids who get regular exercise may breathe in more of an airborne toxin as a result. "This study's findings clearly add to evidence that physical activity may benefit the respiratory health of children, but exposure to high levels of black carbon may lessen this effect," said study researcher Dr. Rachel Miller. She's a professor of environmental health sciences at Columbia University's Mailman School of Public Health in New York City. The research included 129 children from New York City. They were between ages 9 and 14. The kids wore wrist monitors to measure their physical activity levels over six days. Nearly 60 percent of them did 60 minutes or more of moderate to vigorous exercise a day. Compared to the less active children, the active youngsters were exposed to 25 percent more black ...

Scented Rooms, Products? Many Health-Conscious Americans Say 'No Thanks'

Posted 2 Nov 2016 by Drugs.com

WEDNESDAY, Nov. 2, 2016 – Lavender, lemon or lilac: Whatever the artificial aroma, more Americans are avoiding scented spaces and products, a new survey shows. Fragranced products such as soaps, candles and air fresheners cause more than one-third of U.S. adults to suffer ill health effects, including headaches, dizziness and breathing difficulties, researchers said. Surveying a nationally representative group of more than 1,100 Americans, the research team also found that more than 20 percent of people quickly leave a business place if they smell air fresheners or other scented products. Led by Anne Steinemann, a professor of civil engineering at the University of Melbourne in Australia, the research is believed to be the first to examine many aspects of exposure to fragranced products and their effects in the United States. "What I found was that half the reports of adverse health ... Read more

Clean Home May Help Keep Kids' Asthma in Check

Posted 31 Oct 2016 by Drugs.com

MONDAY, Oct. 31, 2016 – Reducing indoor allergens and pollutants can help control children's asthma, reducing their need for medication, according to a new report from the American Academy of Pediatrics. Many things in the home contribute to asthma symptoms and attacks, said report co-author Dr. Elizabeth Matsui. Dust mites and mold top the list, along with furry pets, smoke, cockroaches and airborne fragrances and chemicals. "By intervening, you can have a big impact on your child's asthma," said Matsui, a professor of pediatrics, epidemiology and environmental health sciences at Johns Hopkins Bloomberg School of Public Health in Baltimore. As many as 1 in 10 American kids has asthma, a chronic lung condition that makes it hard to breathe, according to the academy. Their inflamed, narrowed airways lead to wheezing, tightening in the chest, shortness of breath and coughing. The first ... Read more
