Even Thinking an Odor is Harmful May Spur Asthma Symptoms

Posted 4 hours 23 minutes ago by Drugs.com

WEDNESDAY, July 30, 2014 – For patients with asthma, just believing an odor is potentially harmful is enough to trigger airway inflammation for at least 24 hours, a new study indicates. "It's not just what you smell, but also what you think you smell," study author Cristina Jaen, a physiologist at Monell Chemical Senses Center in Philadelphia, said in a Monell news release. "Asthmatics often are anxious about scents and fragrances. When we expect that an odor is harmful, our bodies react as if that odor is indeed harmful," Jaen explained. "Both patients and care providers need to understand how expectations about odors can influence symptoms of the disease." More than 25 million Americans have asthma – a chronic inflammatory disorder that affects the airways and can interfere with quality of life. For people with asthma, certain "triggers" can inflame and constrict the airway, making ... Read more

Obesity During Pregnancy Linked to Raised Asthma Risk in Kids

Posted 8 days ago by Drugs.com

TUESDAY, July 22, 2014 – Women who are obese during pregnancy may be more likely to have children with asthma than normal-weight mothers, a new review suggests. "We found that, compared with children born from mothers of normal weight, those whose mothers were overweight or obese during pregnancy had up to 20 to 30 percent higher odds of asthma," said lead researcher Dr. Erick Forno, an assistant professor of pediatrics at Children's Hospital of Pittsburgh. Forno's team also found that excess weight gain during pregnancy was associated with about a 16 percent increased risk of asthma in the children. "These results included studies that evaluated asthma at different time points in childhood, from a little over a year of age all the way to 16 years of age," Forno noted. Although this review of more than a dozen previously published studies found an association between a mother's weight ... Read more

New Inhaled Drug Shows Promise Against Asthma, Allergies

Posted 3 Jul 2014 by Drugs.com

WEDNESDAY, July 2, 2014 – A new inhaled medication has the potential to treat mild asthma and allergies by interrupting the production of an immune system protein that triggers allergic reactions, a new study reports. The drug, quilizumab, targets the blood cells that produce a protein called immunoglobulin type E (IgE), that serves a key role in allergies. Quilizumab lowered total levels of IgE in the blood of people with allergies and mild asthma, and kept them low for a month, researchers report in the July 2 issue of the journal Science Translational Medicine. "The subjects who received the drug not only had a reduction in their total IgE level, it also seemed to block production of new IgE in response to the allergen they inhaled," said study co-author Dr. Jeffrey Harris, principal medical director of immunology, tissue growth and repair for the drug manufacturer Genentech, which ...

Too-Clean Homes May Encourage Child Allergies, Asthma: Study

Posted 10 Jun 2014 by Drugs.com

FRIDAY, June 6, 2014 – Cleanliness may be next to godliness, but a home that's too clean can leave a newborn child vulnerable to allergies and asthma later in life, a new study reports. Infants are much less likely to suffer from allergies or wheezing if they are exposed to household bacteria and allergens from rodents, roaches and cats during their first year of life, the study found. The results stunned researchers, who had been following up on earlier studies that found an increased risk of asthma among inner-city dwellers exposed to high levels of roach, mouse and pet droppings and allergens. "What we found was somewhat surprising and somewhat contradictory to our original predictions," said study co-author Dr. Robert Wood, chief of the Division of Allergy and Immunology at the Johns Hopkins Children's Center in Baltimore. "It turned out to be completely opposite – the more of ... Read more

Yoga May Not Help Ease Asthma, Study Suggests

Posted 5 Jun 2014 by Drugs.com

THURSDAY, June 5, 2014 – Although yoga is believed to boost physical and mental health, it does not seem to help ease symptoms of asthma, a new study finds. Even so, experts from the American College of Allergy, Asthma and Immunology (ACAAI) noted that if it makes people with asthma feel better they should continue to practice it. "Many asthma sufferers look to complementary therapies, such as yoga, to help relieve their symptoms," Dr. Michael Foggs, an allergist and ACAAI president, explained in a news release from the organization. "If yoga helps them to feel better and breathe better, patients should by all means practice it. At the same time, we don't advise that yoga be recommended to asthma sufferers as a treatment." The researchers analyzed 14 previous studies involving 824 adults from North America, Europe, Asia, Africa and Australia, to find out if yoga could help treat ... Read more

Costs a Barrier to Asthma Care for Some Kids

Posted 25 May 2014 by Drugs.com

THURSDAY, May 22, 2014 – High health insurance co-pays in the United States increase the odds that children with asthma will miss out on important doctor visits and preventive medications, a new survey finds. Parents with higher co-pays reported switching to less expensive drugs, giving their children less medication than prescribed and putting off doctor visits or trips to the emergency room. "Asthma is one of the most common chronic conditions among children, and the prevalence of asthma is greater among low-income populations," said study author Vicki Fung, a health services researcher at Massachusetts General Hospital in Boston. Over 9 percent of U.S. children have the potentially fatal chronic respiratory illness, according to the U.S. Centers for Disease Control and Prevention. Children who are treated early and use medication to prevent asthma flare-ups do better than kids who ... Read more

Children's Asthma Linked to Air Pollution in 2nd Trimester: Study

Posted 19 May 2014 by Drugs.com

MONDAY, May 19, 2014 – Babies born to women exposed to fine particle air pollution during the second trimester of pregnancy may be at greater risk for developing asthma in early childhood, according to a new study. Fine particle air pollution, which can be inhaled deeply, is linked to the greatest health risks, researchers cautioned. These particles can be found in smoke and haze. "We know that mothers' exposure to air pollution during pregnancy can affect lung development of their babies and lead to subsequent respiratory disorders, including asthma, although little is known about whether timing of the exposure is important to consider," said the study's lead author, Yueh-Hsiu Mathilda Chiu, from the department of pediatrics at Icahn School of Medicine at Mount Sinai in New York City. "In our study, we assessed whether higher exposure to particulate air pollution at more specific time ... Read more

Vitamin D Supplements May Not Help Ease Asthma

Posted 18 May 2014 by Drugs.com

SUNDAY, May 18, 2014 – Vitamin D supplements do little to help control asthma, a new study found, although they might help cut the level of medication some patients need. "Previous studies suggested that if you have asthma and low levels of vitamin D in the blood, you have worse lung function, more asthma attacks and more emergency room visits than asthma patients with higher vitamin D levels," Dr. Mario Castro, a professor of pulmonary and critical care medicine at Washington University School of Medicine in St. Louis, explained in a university news release. So, his team decided to conduct "the first randomized controlled trial to investigate whether taking vitamin D supplements can improve asthma control," he said. The study included more than 400 adult asthma patients at nine major medical centers in the United States. All of them had mild to moderate asthma and what was considered ... Read more

Climate Change Will Make Breathing in Summer Harder: Study

Posted 8 May 2014 by Drugs.com

THURSDAY, May 8, 2014 – Summertime ozone air pollution levels in the United States could rise 70 percent by 2050 due to climate change, according to a new study. That means that nearly all regions of the continental U.S. will have at least a few days of unhealthy air during the summers. But heavily polluted areas in the East, Midwest and West Coast that already have many days with high ozone levels could be faced with unhealthy air for most of the summer. "It doesn't matter where you are in the United States – climate change has the potential to make your air worse," study lead author Gabriele Pfister, a scientist at the National Center for Atmospheric Research in Boulder, Colo., said in a center news release. "A warming planet doesn't just mean rising temperatures, it also means risking more summertime pollution and the health impacts that come with it," she added. The ozone that ... Read more

Smoking Bans Linked to Drop in Premature Births, Kids' Asthma Attacks

Posted 28 Mar 2014 by Drugs.com

FRIDAY, March 28, 2014 – Bans on smoking in public places and the workplace in North America and Europe are linked to a 10 percent drop in premature births and the number of children going to the hospital for an asthma flare-up, according to a new study. The study authors said this positive trend occurred within one year of smoke-free policies being put into effect. They added that their findings show smoking bans have significant health benefits for both adults and children. The study was published online March 28 in the journal The Lancet. "Our research found significant reductions in preterm birth and severe asthma attacks in childhood, as well as a 5 percent decline in children being born very small for gestational age after the introduction of smoke-free laws," Dr. Jasper Been, of the Maastricht University Medical Centre, in the Netherlands, said in a journal news release. ...

Traffic Smog Tied to Hospital Stays for White Kids With Asthma

Posted 27 Mar 2014 by Drugs.com

THURSDAY, March 27, 2014 – High levels of traffic-related air pollution greatly increase white children's risk of being readmitted to the hospital due to asthma, a new study finds. Researchers looked at 758 children, aged 1 to 16, who were admitted to Cincinnati Children's Hospital Medical Center for asthma or wheezing. About one-third of the kids were white and nearly two-thirds were black. Within a year after being released from the hospital, 19 percent of the children were readmitted for asthma, the investigators found. White children exposed to high levels of air pollution caused by traffic were three times more likely to be readmitted than those with low levels of exposure, the study authors noted. However, traffic air pollution levels did not affect the risk of readmission among black children, according to the study published in the current issue of the Journal of Pediatrics. ... Read more

Preterm Birth May Raise Child's Asthma Risk, Study Suggests

Posted 13 Mar 2014 by Drugs.com

THURSDAY, March 13, 2014 – A new study may add asthma to the list of downsides of being born too early. Children who were born prematurely appear to be at higher risk for asthma and wheezing disorders, according to a new review. Researchers led by Dr. Aziz Sheikh, of Brigham and Women's Hospital in Boston, looked at 30 studies focused on links between preterm birth – defined as less than 37 weeks' gestation – and asthma or wheezing disorders among more than 1.5 million children. Their analysis found that preterm babies were 70 percent more likely than full-term infants to develop asthma or wheezing disorders later in childhood. Overall, close to 14 percent of "preemie" babies went on to develop asthma during childhood, compared to 8.3 percent of babies born at term. The risk was even higher for very preterm babies, defined as children born at less than 32 weeks' gestation. These ... Read more

September Peak Month for Kids' Asthma Flares: Study

Posted 10 Mar 2014 by Drugs.com

MONDAY, March 10, 2014 – Many parents know that allergies are seasonal, but fewer may realize that the same is true of asthma: A new study suggests the riskiest time for children with asthma is September, as they head back to school. Researchers found that the rates of asthma flares were twice as high in that month as they were in August. Not surprisingly, the study also found a more than two-fold higher rate of prescriptions for asthma rescue inhalers in September compared to August. "Returning to school after summer is strongly associated with an increased risk for asthma exacerbations and unscheduled visits to the primary care physician," wrote researcher Dr. Herman Avner Cohen, of the Sackler Faculty of Medicine at Tel Aviv University, in Israel. Results of the study were released online March 10 and will be published in the April print issue of Pediatrics. Asthma is a chronic ... Read more
