Higher Risk Of Childhood Asthma From Depressed Mothers

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

The study was supported by a grant of the National Institute of Environmental Health Sciences and the Environmental Protection Agency.

Charging Implanted Heart Pumps Wirelessly

Mechanical pumps to give failing hearts a boost were originally developed as temporary measures for patients awaiting a heart transplant. But as the technology has improved, these ventricular assist devices commonly operate in patients for years, including in former vice-president Dick Cheney, whose implant this month celebrates its one-year anniversary. Prolonged use, however, has its own problems. The power cord that protrudes through the patient's belly is cumbersome and prone to infection over time. Infections occur in close to 40 percent of patients, are the leading cause of rehospitalization, and can be fatal. Researchers at the University of Washington and the University of Pittsburgh Medical Center have tested a wireless power system for ventricular assist devices. They recently presented the work in Washington, D.C. at the American Society for Artificial Internal Organs annual meeting, where it received the Willem Kolff/Donald B. Olsen Award for most promising research in

Autism and Eye Contact: Genes very much are involved

We have now a lot of evidence on genetic components in many disorders including neurological in both adults and kids. Autism is one such problem that has many genes involved. Research is still in full swing to find more genes and related pathways. However, one can find autistic features more phenotypically before genotyping. Eye contact is one of them. Studies have shown that autistic kids make less eye contact. This has been shown to have genetic component now. New research has uncovered compelling evidence that genetics plays a major role in how children look at the world and whether they have a preference for gazing at people's eyes and faces or at objects. The discovery by researchers at Washington University School of Medicine in St. Louis and Emory University School of Medicine in Atlanta adds new detail to understanding the causes of autism spectrum disorder. The results show that the moment-to-moment movements of children's eyes as they seek visual information about the

How much people depend on weather reports

Meteorologists on television, radio, online, and in newspapers supply weather reports to the average person over 100 times a month. Surveys demonstrated that the 300 billion forecasts accessed generate a value of $285 per household every year, or $32 billion for the entire United States. Odds are you have already watched one weather forecast today and will probably check out a few more. Accurate, timely forecasts are vital to everyday life, but just how critical may surprise you. Whether at work or play, you probably watch the weather quite closely. Most of us are at the weather person's mercy to know what to wear, what to expect, to prepare for the worst. New research shows the average United States household checks out a weather report more than three times a day. "It impacts pretty much every part of every activity we are involved with for the most part," Jeff Lazo, the director of the Societal Impacts Program at the National Center for Atmospheric Research (NCAR) in B
