Work-Related Asthma a Significant Problem: CDC

Posted 3 days ago by Drugs.com

THURSDAY, May 24 – About nine percent of all asthma cases in the United States are caused or made worse by work-related exposures, a new federal study says. That means work-related asthma affects about 1.4 million adults annually, the researchers said. State-by-state rates of workplace-related asthma ranged from 4.8 percent (Arizona) to just over 14 percent (Florida), according to the study by researchers at the U.S. Centers for Disease Control and Prevention. The analysis of 2006-09 data from 38 states and the District of Columbia also suggests that older workers and those in certain ethnic or minority groups are most at risk. For example, rates of employment-related asthma were 12.7 percent for people ages 45-64 vs. about 7 percent for people ages 18-44. Among racial groups rates of work-related asthma were 12.5 percent for blacks, 10.5 percent for Hispanics and 8.2 percent for ... Read more

Breathing Smog While Pregnant May Worsen Asthma in Offspring

Posted 7 days ago by Drugs.com

SUNDAY, May 20 – Exposure to air pollution while in the womb might harm the lung-function development of children with asthma, a new study finds. Researchers conducted repeated evaluations of 162 asthmatic children between the ages of 6 and 15 in Fresno, Calif., and used U.S. Environmental Protection Agency data to determine the children's mothers' exposure to air pollution during pregnancy. The study showed that exposure to airborne particles and the pollutant nitrogen dioxide during the first and second trimesters was associated with poorer lung function growth in both boys and girls with asthma. The study was scheduled for presentation Sunday at an American Thoracic Society conference, in San Francisco. The findings add to existing evidence that a mother's exposure to air pollution during pregnancy can have long-term effects on lung-function development in children with asthma, said ... Read more

Asthma Cases Continue to Rise in U.S., Affecting Millions

Posted 12 days ago by Drugs.com

TUESDAY, May 15 – Asthma continues to take its toll on Americans, with almost 19 million adults (8.2 percent) suffering from the disorder in 2010, according to a report released Tuesday by the U.S. Centers for Disease Control and Prevention. The CDC analysis also found that more than 29 million (almost 13 percent) of adults have been diagnosed with the illness at some point in their lifetime. Children are also being hit hard by the wheezing and discomfort of asthma. According to the report, in 2010 about 10 million children had been diagnosed with asthma in their lifetime and 7 million (9.4 percent) still had asthma. Rates of asthma are rising, not falling, the experts noted. From 2001 to 2010, the proportion of people with asthma increased by almost 15 percent. And by 2009, asthma accounted for nearly 3,400 deaths, nearly 480,000 hospitalizations, 1.9 million emergency department ... Read more

Inhaled Steroids Lead to Big Drop in Asthma Deaths at Texas Hospital: Study

Posted 12 days ago by Drugs.com

TUESDAY, May 15 – Patient education and medication compliance contributed to a 74 percent drop in the number of patients with life-threatening asthma admitted to the intensive care unit at University Hospital in San Antonio, Texas, researchers report. Their review of 30 years of hospital data focused on patients with severe asthma who didn't respond to standard inhalers. They found that there were 227 patients admitted to the intensive care unit (ICU) with 280 episodes of life-threatening asthma between 1980 and 2010. One patient died, but the death was from a different cause after the patient's asthma improved, according to the team at the University of Texas Health Science Center at San Antonio. "The main reason for the decline in cases is that more of our patients are taking their controller medications, such as inhaled corticosteroids, which reduce the amount of inflammation in the ...

Seniors Undertreated for Asthma, and Many Skip Inhalers: Study

Posted 1 May 2012 by Drugs.com

TUESDAY, May 1 – Asthma often is misdiagnosed and undertreated in older people, with only 53 percent of those with asthma using prescribed inhalers, a small new study suggests. The study included 77 people, including people both with and without asthma, who were over age 60. Of those with asthma, 89 percent also had allergies to mold, animals or dust mites. The asthma patients were more likely than those without asthma to have hay fever, arthritis, diabetes, higher levels of pain and poor general health than those without asthma. The study appears in the May issue of the journal Annals of Allergy, Asthma & Immunology. "Those with asthma reported more infections, physician visits and impact on health, yet only half are regularly treating the disease," lead author and allergist Dr. Andrew Smith said in a journal news release. "Patients should regularly carry and take prescribed asthma ... Read more

Many Asthmatic Kids Harmed by Secondhand Smoke: Study

Posted 1 May 2012 by Drugs.com

TUESDAY, May 1 – Many asthmatic children in the United States are exposed to secondhand tobacco smoke and suffer health problems because of it, a new study shows. "National asthma guidelines have advised avoidance of environmental tobacco smoke for patients with asthma for decades, but it is unclear to what degree these recommendations are being followed and what the impact of exposure has been in an era of increased awareness of the effects of environmental tobacco smoke exposure," study author Dr. Lara Akinbami, medical officer at the National Center for Health Statistics of the Centers for Disease Control and Prevention, said in an American Academy of Pediatrics news release. The researchers analyzed data from the National Health and Nutrition Examination Survey from 2003 to 2010 for 972 children aged 6 to 19 with asthma. The results showed that 53 percent of the children were ... Read more

Children Usually Excluded From Clinical Drug Trials: Study

Posted 30 Apr 2012 by Drugs.com

MONDAY, April 30 – Children are more likely than adults to suffer from a number of diseases, but few clinical trials are conducted to test new drugs in children with these conditions, researchers have found. In a new study, researchers looked at all clinical trials registered worldwide from 2006 to 2011 for drugs to treat these common conditions: asthma, migraine headaches, schizophrenia, depression, diarrheal illness, lower respiratory infection, malaria, bipolar disorder and HIV/AIDS. While children account for 60 percent of the patients with these conditions, only 12 percent of the clinical drug trials involved children, the investigators found. The gap was widest for conditions that are widespread in low- and middle-income countries. Clinical drug trials in children are important because youngsters often respond differently to medications than adults, the study authors pointed out ... Read more

Some Schools Don't Let Kids Carry Asthma Inhalers

Posted 27 Apr 2012 by Drugs.com

FRIDAY, April 27 – Although all 50 states have laws that allow children with asthma to carry inhalers at school and 48 states have laws that let youngsters carry epinephrine pens for serious allergies, experts say that some kids are still being denied access to these lifesaving medications during the school day. "Every school district handles this a little bit different, and for those who don't allow children to carry their medications, I think may be due to a lack of knowledge. School officials may not appreciate the risk that having epinephrine pens and inhalers in a locked office, instead of with the child, can pose," said Maureen George, an assistant professor at the University of Pennsylvania School of Nursing in Philadelphia. "Fewer than 200 children die each year from asthma in the U.S. That number is low, but those deaths are preventable. And it's a double tragedy when you lose ... Read more

More Smog Might Mean More Hospitalizations

Posted 18 Apr 2012 by Drugs.com

WEDNESDAY, April 18 – Long-term exposure to fine-particle air pollution may increase older adults' risk of being hospitalized for lung and heart disease, stroke and diabetes, a new study says. Harvard School of Public Health researchers compared air-quality data with hospital admission records on all Medicare patients aged 65 and older admitted to 3,000 New England hospitals between 2000 and 2006. The researchers focused on fine air particles known as PM2.5, which have a diameter of 2.5 microns or less and are narrower than the width of a human hair. These particles – emitted by vehicles, power plants, wood-burning devices and some industrial processes – can lodge in the lungs and cause inflammation throughout the body. "Our study found that long-term rates of admissions for pneumonia, heart attacks, strokes and diabetes are higher in locations with higher long-term average particle ... Read more

Alternative Therapies Aren't Used as Substitutes for Asthma Meds: Study

Posted 13 Apr 2012 by Drugs.com

FRIDAY, April 13 – Almost one in five parents has turned to an alternative or complementary medicine or treatment for their child's asthma, but new research has found that parents are not abandoning traditional treatments in the process. "We found that there were really no differences between the groups that used complementary and alternative medicine and those that didn't [in terms of adherence]. It seems that parents are using these therapies as complementary medicine alongside prescribed asthma treatments," said study author Dr. Julie Philp, a pediatrician and a dermatology resident at the University of California, San Francisco. Results of the study were released online and published in the May issue of Pediatrics. Complementary and alternative medicine includes health care practices that aren't usually included in more conventional medicine. Such treatment may include herbal ... Read more

Climate Change Could Be Tough on Seniors' Health: Study

Posted 9 Apr 2012 by Drugs.com

MONDAY, April 9 – Even small swings in temperatures could put elderly people with chronic illnesses such as diabetes, heart failure and lung disease at greater risk of death throughout the coming summer, a new study indicates. Researchers from the Harvard School of Public Health in Boston found temperature fluctuations related to climate change could claim thousands of lives every year. Experts predict climate change could increase variations in summer temperatures, particularly in the mid-Atlantic states and in parts of France, Spain and Italy. In these more volatile regions, this could pose a serious public health risk, the study authors claimed. "The effect of temperature patterns on long-term mortality has not been clear to this point. We found that, independent of heat waves, high day-to-day variability in summer temperatures shortens life expectancy," study author Antonella ... Read more

Rapid Asthma Treatment in ER May Prevent Admission

Posted 6 Apr 2012 by Drugs.com

FRIDAY, April 6 – Rapid treatment with asthma medications seems to help reduce hospitalizations among children with asthma, a new study finds. Canadian researchers analyzed data from 406 children and found that those with moderate or severe asthma attacks who received systemic corticosteroids within 75 minutes of arriving at a hospital emergency department were 16 percent less likely to be admitted to the hospital. Corticosteroids reduce inflammation. The findings illustrate the importance of rapidly identifying and treating children with asthma when they arrive at an emergency department, the researchers said. The study was recently published online in the journal Annals of Emergency Medicine. "We knew that corticosteroids could help avoid hospital admissions and relapses. However, just how delays between emergency department admission and administration of the treatment impacted ... Read more

High Out-of-Pocket Costs for Kids' Asthma Drugs Could Pose Dangers

Posted 27 Mar 2012 by Drugs.com

TUESDAY, March 27 – When health insurers require parents to pay a larger share of the cost of asthma medications for their children, more kids need emergency asthma treatment, suggests new research. For children older than 5, higher out-of-pocket costs results in a small reduction in medication use and greater rates of hospitalization for asthma complications, the study found. "Asthma is the most common chronic disease in children. We looked at adherence to asthma medications that are intended to be taken year-round to prevent exacerbations [flare-ups]," said one of the study's authors, Dr. Anupam Jena, a physician at Massachusetts General Hospital and Harvard Medical School and a senior fellow at the Schaeffer Center for Health Policy and Economics at the University of Southern California. Jena said that adherence rates for these medications – the rate at which patients stick to ... Read more

Amish Farm Kids Have Lower Asthma, Allergy Risk: Study

Posted 6 Mar 2012 by Drugs.com

TUESDAY, March 6 – Children growing up in the Amish culture in Switzerland have significantly less asthma and allergies than Swiss children who didn't grow up on a farm, according to new research. What's more, the Amish youngsters even have less risk of asthma and allergy than Swiss children who grew up on non-Amish farms. The study could support the "hygiene hypothesis" that a too-clean world is causing today's urbanized kids to be more sensitive to allergens than their country cousins. "In Europe, children living on traditional farms seem to have a very low prevalence of asthma and allergy," noted the study's lead author, Dr. Mark Holbreich, an allergist with Allergy and Asthma Consultants, in Indianapolis. In contrast, he said, "in the general population as many as 50 percent will have evidence of allergic sensitivity. They may not have all the symptoms of allergy, but they will ... Read more

Children With Asthma at Higher Risk for Shingles: Study

Posted 5 Mar 2012 by Drugs.com

MONDAY, March 5 – Children with asthma have a higher risk for developing shingles – a painful skin rash – following infection with the herpes zoster virus, new research reveals. The authors noted that 1 million Americans are estimated to be infected with the herpes zoster virus every year. However, typically it's a problem that strikes men and women over the age of 60 or people with weakened immune systems. Researchers analyzed 277 medical records involving patients under the age of 18 who had experienced an episode of shingles between 1996 and 2001. Stacking up the shingles cases against 277 children who had no history of shingles, the team found that asthmatic patients were 2.2 times more likely to have a case of shingles compared to those who did not have asthma. While 23 percent of the shingles patients had a history of asthma before the onset of shingles, only 35 patients ... Read more
