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

Common Asthma Meds May Raise Sleep Apnea Risk, Study Says

Posted 28 Feb 2014 by Drugs.com

FRIDAY, Feb. 28, 2014 – Medicines commonly used to control asthma may increase the risk of a potentially serious sleep problem in some people, a small, early study suggests. "Inhaled corticosteroids may predispose to sleep apnea in some asthma patients," said study author Dr. Mihaela Teodorescu, an associate professor of medicine at the University of Wisconsin School of Medicine and Public Health, in Madison. In sleep apnea, breathing periodically stops during sleep, for a few seconds or even minutes at a time, according to the U.S. National Heart, Lung, and Blood Institute. The pauses can occur as often as 30 times or more in a single hour. In the most common type of apnea, the airway becomes blocked or collapses during sleep. If untreated, apnea can increase the risk of high blood pressure, heart attack, stroke and other problems. However, the new study linking asthma medicines with ... Read more

Black Children, Teens More Likely to Return to Hospital for Asthma: Study

Posted 3 Feb 2014 by Drugs.com

MONDAY, Feb. 3, 2014 – Financial and social hardships are the major reasons black children and teens are twice as likely as whites to be readmitted to the hospital for asthma, a new study suggests. Researchers looked at nearly 800 asthma patients, aged 1 to 16, who were admitted to Cincinnati Children's Hospital Medical Center between August 2010 and October 2011. Fifty-seven percent of the patients were black. Overall, 19 percent of the children were readmitted to the hospital within a year. This included 23 percent of blacks and 11 percent of other children, most of whom were white, according to the study, which was published online Feb. 3 in the journal Pediatrics. Caregivers of black children were much more likely to say they had financial and social hardships, such as being jobless and not having a car. These hardships accounted for about 40 percent of the racial disparity in ... Read more

Premature Birth Linked to Asthma, Wheezing in Childhood

Posted 28 Jan 2014 by Drugs.com

TUESDAY, Jan. 28, 2014 – A new analysis of existing research suggests that premature babies face a higher risk of developing asthma and wheezing disorders when they're older. Researchers from Harvard Medical School, the Maastricht University Medical Center in the Netherlands and the University of Edinburgh in Scotland examined 30 studies that included about 1.5 million children. They found that premature children (born before 37 weeks of gestation) were 46 percent more likely to develop asthma or wheezing problems than kids who weren't born prematurely. Full-term birth is generally considered about 40 weeks' gestation. Very premature children (those born before 32 weeks' gestation) faced an even higher estimated risk – almost three times that of children born at full term, said Jasper Been, from Maastricht University, and his colleagues. About 11 percent of children are born ... Read more

Testing for Smoke Exposure May Predict Rehospitalization for Asthma

Posted 22 Jan 2014 by Drugs.com

MONDAY, Jan. 20, 2014 – Children exposed to secondhand smoke at home or in the car are more likely to return to the hospital within 12 months of hospitalization for asthma, a new study finds. The researchers said tests of tobacco exposure have the potential to help protect those kids by identifying caregivers who may need help to quit smoking. "The ability to measure serum and salivary cotinine levels [a marker for tobacco exposure] presents the possibility of an objective measure that can be obtained when a child is seen in the emergency department or in the hospital, and may be used to predict future hospitalizations," study senior author Dr. Robert Kahn, associate director of general and community pediatrics at Cincinnati Children's Hospital, said in a hospital news release. "Such a measure for exposure to tobacco smoke could be used to target specific interventions at caregivers of ... Read more

Many Asthma Patients Don't Stick to Treatment Plan, Study Finds

Posted 21 Jan 2014 by Drugs.com

SATURDAY, Jan. 18, 2014 – If you can't get relief from your asthma, the way you communicate with your allergist might be part of the problem, according to two new studies. The researchers said asthma patients need to ask questions and have open communication with their allergists for their treatment to be effective. One study found that only 8 percent to 13 percent of asthma patients continue to refill inhaled corticosteroid prescriptions after one year. These medications, when taken early and as prescribed, may help improve asthma control, normalize lung function and possibly prevent permanent injury to the airways, the researchers said. "When patients do not understand their condition or treatment plan, they may not follow life-saving guidelines, putting them at increased risk for asthma attacks," study author Dr. Stanley Fineman, former president of the American College of Allergy, ...

Less Variety in Babies' Gut Bacteria May Lead to Asthma Risk

Posted 13 Jan 2014 by Drugs.com

FRIDAY, Jan. 10, 2014 – Infants with fewer types of intestinal bacteria are at increased risk for developing asthma, a small new study suggests. Researchers assessed the varieties of gut bacteria in 47 infants and then followed them until they were 7 years old. At that age, 17 percent had chronic asthma, 28 percent had hay fever, 26 percent had the skin condition eczema, and 34 percent reacted to the allergens in a skin prick test. However, only the cases of asthma could be connected to low diversity of intestinal bacteria when the children were 1 week and 1 month old, according to the study recently published in the journal Clinical & Experimental Allergy. The findings may provide further evidence that bacteria in the intestines can affect the airways, which has previously been shown in animal studies, the researchers say. "A high diversity of gut [microbes] during the first months of ... Read more

Dogs May Guard Babies Against Asthma, Allergies

Posted 16 Dec 2013 by Drugs.com

MONDAY, Dec. 16, 2013 – Researchers say they've discovered why infants who live in homes with a dog are less likely to develop asthma and allergies later in childhood. The team conducted experiments with mice and found that exposing them to dust from homes where dogs live triggered changes in the community of microbes that live in the infant's gut and reduced immune system response to common allergens. The scientists also identified a specific species of gut bacteria that's crucial in protecting the airways against allergens and viruses that cause respiratory infections, according to the study published online Dec. 16 in the Proceedings of the National Academy of Sciences. While these findings were made in mice, they're also likely to explain why children who are exposed to dogs from the time they're born are less likely to have allergies and asthma, the University of California, San ...

Probiotics Don't Prevent Childhood Asthma, Study Finds

Posted 11 Dec 2013 by Drugs.com

WEDNESDAY, Dec. 11, 2013 – Probiotics – friendly bacteria found in supplements and some yogurts – don't prevent childhood asthma, but they may provide other health benefits, according to a new study. Researchers in Canada found that taking probiotics during pregnancy or giving probiotics to infants during the first year of life does not reduce the prevalence of asthma. "Taking probiotics had no effect on the asthma rate," said the study's principal investigator, Meghan Azad, a post-doctoral fellow in the faculty of medicine and dentistry at the University of Alberta. "We haven't shown there's any harm in giving probiotics, but it can't really be advised as a strategy to prevent asthma." The study, published online Dec. 4 in the BMJ, involved information compiled from 20 clinical trials in Europe, Australia, New Zealand and Taiwan on more than 4,800 children. The children either had ... Read more

Nebulizers May Not Deliver Full Drug Dose to Kids With Asthma

Posted 6 Dec 2013 by Drugs.com

FRIDAY, Dec. 6, 2013 – Nebulizers – devices that transform liquid asthma medications into an easy-to-inhale mist – aren't providing people with asthma a full dose of medication, according to a small new study. Researchers found that less than 20 percent of the prescribed medication actually makes it into the lungs. "Our study demonstrated that the prescribed dose bears little resemblance to the proportion of the drug children actually inhaled, and that [the amount they inhaled] was largely dependent on the formulation of the drug," said Dr. Ahmad Kantar, head of the pediatric unit at the Institute Hospital Bergamo in Ponte San Pietro, Italy. The study results were published online recently in the journal Respirology. Although used less commonly than metered dose inhalers, nebulizers often are relied on in emergency situations and for younger children who may have a difficult time ... Read more

Too Few Americans With Asthma Are Getting Flu Shots, CDC Says

Posted 5 Dec 2013 by Drugs.com

THURSDAY, Dec. 5, 2013 – People with asthma face special risks from influenza, and a new report suggests far too few American asthma patients receive the seasonal flu shot. "Asthmatics are at increased risk for complications from the flu," said one expert, Dr. Len Horovitz, a pulmonary specialist at Lenox Hill Hospital in New York City. "Exacerbations [flare-ups] of asthma are common with any viral infection, but the exacerbation from the flu is particularly severe." The new study, led by Matthew Lozier of the U.S. Centers for Disease Control and Prevention, looked at flu shot uptake during the 2010-2011 flu season. The investigators found that only half of Americans with asthma got a flu shot – a figure that was at least an improvement on the rate of 36 percent observed in the 2005-2006 flu season. However, despite this increase, flu vaccination rates for people with asthma remain ... Read more
