(Press-News.org) ATS 2013, PHILADELPHIA ─ Air pollutants from traffic are associated with increased asthma severity levels in pregnant asthmatic women, according to a new study.
"Air pollution is a known trigger for asthma symptoms," said lead author Janneane Gent, PhD, Research Scientist in Epidemiology (Environmental Health) at the Yale School of Public Health. "In our study, exposures were assessed using a sophisticated air pollution modeling system (Community Multiscale Air Quality, CMAQ) that permits community-level estimates (i.e., close to where the subject resides) instead of assigning regional measurements made at Environmental Protection Agency (EPA) central site monitors to all subjects. Using community-level estimates, we found that exposure to nitrogen dioxide at levels much lower than the current EPA standard was associated with increased risk of asthma morbidity."
The results of the study will be presented at the ATS 2013 International Conference.
The study enrolled 637 pregnant women ( END

Study finds air pollution and noise pollution increase cardiovascular risk
2013-05-21
ATS 2013, PHILADELPHIA ─ Both fine-particle air pollution and noise pollution may increase a person's risk of developing cardiovascular disease, according to German researchers who have conducted a large population study, in which both factors were considered simultaneously.
"Many studies have looked at air pollution, while others have looked at noise pollution," said study leader Barbara Hoffmann, MD, MPH, a professor of environmental epidemiology at the IUF Leibniz Research Institute for Environmental Medicine in Germany. "This study looked at both at the same ...
Prenatal exposure to traffic is associated with respiratory infection in young children
2013-05-21
ATS 2013, PHILADELPHIA ─ Living near a major roadway during the prenatal period is associated with an increased risk of respiratory infection developing in children by the age of 3, according to a new study from researchers in Boston.
"The connection between in utero and early life cigarette smoke exposure and adverse infant respiratory outcomes is well-established, but the relation of prenatal ambient air pollution to risk of infant respiratory infection is less well-studied," said lead author Mary Rice, MD, a pulmonary and critical care fellow at Massachusetts ...
Early childhood respiratory infections may explain link between analgesics and asthma
2013-05-21
ATS 2013, PHILADELPHIA ─ A new study conducted by Boston researchers reports that the link between asthma and early childhood use of acetaminophen or ibuprofen may be driven by underlying respiratory infections that prompt the use of these analgesics, rather than the drugs themselves.
The results of the new study will be presented at the ATS 2013 International Conference.
Analgesics like ibuprofen and acetaminophen are routinely given to treat fever in infants, and several studies have shown a link between the use of analgesics during infancy and the subsequent ...
Combined wood and tobacco smoke exposure increases risk and symptoms of COPD
2013-05-21
ATS 2013, PHILADELPHIA ─ People who are consistently exposed to both wood smoke and tobacco smoke are at a greater risk for developing chronic obstructive pulmonary disease (COPD) and for experiencing more frequent and severe symptoms of the disease, as well as more severe airflow obstruction, than those who are exposed to only one type of smoke, according to the results of a new population-based study conducted by researchers in Colombia.
The results of the study will be presented at the ATS 2013 International Conference.
"Although previous studies have shown ...
May/June 2013 Annals of Family Medicine tip sheet
2013-05-21
Much of the May/June 2013 issue of Annals of Family Medicine and the entirety of an accompanying supplement published in partnership with the U.S. Agency for Healthcare Research and Quality are about changing primary care practice. Practice transformation on a large scale toward the patient-centered medical home model of care is a cornerstone of health care reform efforts in the United States, and the research and commentary in this issue can serve as a roadmap to achieve practice transformation. Not only do the articles address the opportunities, challenges, costs, processes ...
Whole-cell vaccine was more effective than acellular vaccine during California pertussis outbreak
2013-05-21
OAKLAND, Calif., May 20, 2013 — Whole-cell pertussis vaccines were more effective at protecting against pertussis than acellular pertussis vaccines during a large recent outbreak, according to a new Kaiser Permanente study published in Pediatrics.
Whole-cell pertussis vaccines, also called DTwP, were available from the 1940s to 1990s, but were associated with safety concerns that ultimately led to the development of acellular pertussis vaccines, which are also called DTaP. By the late 1990s, the United States had switched from whole-cell to acellular vaccines for all ...
Principles of locomotion in confined spaces could help robot teams work underground
2013-05-21
Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much-despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar to people living in the southern United States.
By studying fire ants in the laboratory using video tracking equipment and X-ray computed tomography, researchers have uncovered fundamental principles of locomotion that robot teams could one day use to travel quickly and easily through underground tunnels. Among the principles is building tunnel environments that ...
Intestinal bacteria protect against E. coli O157:H7
2013-05-21
A cocktail of non-pathogenic bacteria naturally occurring in the digestive tract of healthy humans can protect against a potentially lethal E. coli infection in animal models according to research presented today at the 113th General Meeting of the American Society for Microbiology. The research, conducted by scientists at the University of Michigan Medical School in Ann Arbor, could have important implications for the prevention or even treatment of this disease.
Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is a food-borne pathogen that has been responsible for ...
Leading explanations for whooping cough's resurgence don't stand up to scrutiny
2013-05-21
ANN ARBOR—Whooping cough has exploded in the United States and some other developed countries in recent decades, and many experts suspect ineffective childhood vaccines for the alarming resurgence.
Some say the vaccine wears off quicker than public health officials had previously believed. Others suggest that the vaccine protects against illness but does not prevent transmission of the bacterial disease, which is also known as pertussis.
But a University of Michigan-led research team has concluded that neither of these proposed mechanisms for the resurgence of pertussis ...
Hospitals' cardiac arrest incidence and survival rates go hand in hand
2013-05-21
ANN ARBOR, Mich. — Hospitals with the highest rates of cardiac arrests tend to have the poorest survival rates for those cases, new University of Michigan Health System research shows.
Meanwhile, hospitals that do the best job of preventing cardiac arrest among their patients tend to be better at saving patients with cardiac arrest, according to the findings that appear in JAMA Internal Medicine.
These results were not entirely expected, say researchers. For conditions other than cardiac arrest, higher volume has been associated with better outcomes for patients. ...
