(Press-News.org) July 5, 2011– Anxiety, stress and depression during pregnancy may lead to a greater risk of asthma for your child, according to researchers at Columbia University's Mailman School of Public Health. Study results are published in the July issue of Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI).
"Approximately 70% of mothers who said they experienced high levels of anxiety or depression while they were pregnant reported their child had wheezed before age 5," said Marilyn Reyes, senior research worker at the Mailman School of Public Health's Columbia Center for Children's Environmental Health (CCCEH), and lead author of the study. "Understanding how maternal health affects a child's respiratory health is important in developing effective strategies to prevent asthma."
The study of 279 inner-city African-American and Hispanic women was conducted before, during pregnancy and after birth. The findings support a growing body of research showing that exposures can influence the risk of developing asthma. While somewhat similar findings have been reported in non-minority populations, this study is the first to report an association between prenatal psychological stress and wheeze in minority populations.
"The symptoms of pediatric asthma can range from a nagging cough that lingers for days or weeks to sudden and scary breathing emergencies," said allergist/pulmonologist Rachel Miller, MD, Co-Deputy Director of CCCEH and study senior author. "While low-income families experience stressors from many sources that may contribute to adverse health outcomes in children, understanding how children's health may be influenced by these factors is an important step in developing effective interventions."
Common asthma symptoms include:
Coughing, especially at night
Wheezing or whistling sound, especially when breathing out
Trouble breathing or fast breathing that causes the skin around the ribs or neck to pull in tightly
Frequent colds that settle in the chest

Researchers at the Johns Hopkins University School of Medicine have developed a technique that delivers gene therapy into human brain cancer cells using nanoparticles that can be freeze-dried and stored for up to three months prior to use. The shelf-stable particles may obviate the need for virus-mediated gene therapy, which has been associated with safety concerns. The report appears in the August issue of Biomaterials.
"Most nonviral gene therapy methods have very low efficacy," says Jordan Green, Ph.D., an assistant professor of biomedical engineering at Johns Hopkins. ...
A significant discovery by University of Adelaide researchers shows that the loss of a twin during early pregnancy explains the increased risk of birth defects in multiple IVF pregnancies.
The annual meeting of the European Society of Human Reproduction and Embryology in Stockholm today will hear Associate Professor Michael Davies explain how the "vanishing twin" phenomenon is linked to a nearly two-fold increased risk of congenital malformation in the surviving baby, and a threefold increase in multiple birth defects.
The phenomenon occurs when there are fewer babies ...
ST. PAUL, Minn. – New research finds breastfeeding doesn't appear to protect against multiple sclerosis (MS) relapses, despite previous studies suggesting there may be a protective role. The research is published in the July 6, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology (AAN).
"Breastfeeding should not be encouraged by doctors to protect against MS relapses, especially among women with MS who have high disease activity and high risk of postpartum relapses," said study author Emilio Portaccio, MD, of the University of Florence ...
If Canada's smoking rates were cut by half to an average national rate of 11% within five years, it would result in 35,900 fewer cases of lung cancer by 2030 and save $656 million in treatment costs, according to analysis using a new web-enabled platform developed for the Canadian Partnership Against Cancer and presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer (IASLC).
"The Cancer Risk Management simulation model developed for the Canadian Partnership Against Cancer simulates the demographic ...
Women, older people and minorities are enrolled less frequently in lung cancer drug trials and the numbers do not reflect the prevalence of lung cancer in these populations, according to research presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer (IASLC).
"Our results suggest that the trial population used for approval of drugs do not represent well the U.S. population who may receive the marketed agent," said principal investigator Dr. Shakun Malik, a medical officer at the U.S. Food ...
New developments such as stereotactic ablative radiotherapy and improvements in surgical care in early-stage lung cancer have led to large survival gains for elderly Dutch patients, according to a population-based study presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer (IASLC).
The median survival for Dutch non-small cell lung cancer (NSCLC) patients increased by nearly 8 months between 2003 and 2009, following the advent of stereotactic ablative radiotherapy.
"In fit patients, surgery ...
Increased investment in specialist thoracic surgical expertise can lead to a significant rise in the lung cancer resection rate, based on data from England between 2008 and 2009 that was presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer (IASLC).
In England, lung cancer resection is less common than in other countries, and is performed by
both cardiothoracic and pure thoracic surgeons. Researchers tested the hypotheses that resection rate was related to the caseload and local provision ...
PHILADELPHIA — Celecoxib may emerge as a potent chemopreventive agent for lung cancer, according to a recent study in Cancer Prevention Research, a journal of the American Association for Cancer Research.
Researchers tested celecoxib, a COX-2 inhibitor, among patients who were former smokers and found a significant benefit in bronchial health as measured by the Ki-67 labeling index, a marker of cellular proliferation or growth, as well as a number of other biomarkers. The findings follow a previous report published in Cancer Prevention Research that showed a similar effect ...
(Deerfield, Ill., USA - July 6, 2011) A cheap, common heartworm medication that is already being used to fight other parasites in Africa could also dramatically interrupt transmission of malaria, potentially providing an inexpensive tool to fight a disease that kills almost 800,000 people each year, according to a new study published today in the July edition of the American Journal of Tropical Medicine and Hygiene.
The study by scientists from Senegal and Colorado State University found that transmission of malaria parasites by mosquitoes fell substantially among people ...
Professional development workshops for college teachers, designed to encourage the use of active, "learner-centered" teaching methods, may be less effective than the participants believe, according to research reported in the July issue of BioScience.
Diane Ebert-May of Michigan State University and her colleagues studied the teaching of participants in two such established programs for faculty teaching introductory biology courses. Although after the workshops most of the faculty judged themselves to be providing the favored, learner-centered teaching, which encourages ...
