  • Smoking during pregnancy can be very dangerous
  • It can lead to asthma and poor lung function in the baby
  • It also can have serve effects on the health of the mother

Women who smoke while pregnant contribute to the severity of asthma and poor lung function in their children warns a study.

The findings published in the journal CHEST suggest that tobacco smoke exposure during pregnancy is more strongly associated with worse lung function than current, ongoing exposure in school-aged children with asthma.

Smoking during pregnancy can be unhealthy for the child.

“This study implicates maternal smoking in pregnancy as the period of second-hand exposure that is more strongly associated with worse lung function in asthmatic children,” said lead investigator Stacey-Ann Whittaker Brown from Icahn School of Medicine at Mount Sinai, New York.

“Maternal smoking in pregnancy may set children with asthma on a trajectory of poor lung function in later childhood, and other studies suggest this effect may be lifelong,” Whittaker Brown said.

Investigators analysed the relationship between lung function and the type of second-hand smoke exposure in a representative sample of school-aged children aged six to 11 years.

The sample consisted of 2,070 children who participated in the 2007-2012 National Health and Nutrition Examination Survey (NHANES) in the US.

Detailed information about ongoing second-hand smoke exposure as well as parental self-reported exposure prior to birth was obtained.

During the study period, lung function was measured using spirometry, and exposure to smoking was assessed through levels of cotinine in the blood, a marker of the extent of current second-hand smoke exposure. Thus, investigators were able to distinguish clearly between exposure in pregnancy and ongoing second-hand smoke exposure.

Nearly 10 percent of both children with and without asthma in the sample had reduced lung function.

Investigators found that current tobacco smoke exposure was independently associated with airflow obstruction in school-aged children, although the extent of the association was small.

However, prenatal tobacco smoke exposure was associated with a 2.5 times increase in odds of having airflow obstruction in children with asthma, the study said. IANS

Paralyzed Patients Start Walking Following A New Treatment

the researchers say this is not a cure for paralysis, and caution that it may not work on every patient. They say more study is needed.

U.S. researchers are reporting progress in helping those paralyzed by spinal cord injuries to stand, and even to take steps.

Two teams of medical researchers working separately say an electrical implant that stimulates the spinal cord allowed three paralyzed patients to stand and move forward while they held on to a walker or were supported from the back.

One patient was able to walk the length of a football field.

“Recovery can happen if you have the right circumstances,” University of Louisville professor Susan Harkema said, adding that the spinal cord can “relearn to do things.”

Experts say that a damaged spinal cord leaves the brain unable to send messages to the nerves that activate the muscles.

The researchers believe those nerves are still alive, but are asleep.

Stimulating them with electricity, along with intense rehabilitation, can wake up those sleeping nerves and enable them to receive commands again.

Other earlier treatments using electricity allowed patients to stand and move their toes, but not walk.
