Panic Disorder Increases the Risk of Adverse Birth Outcomes
Dec 8th
Anxiety often results in the activation of the sympathetic nervous system. This activation is commonly known as the “fight or flight response”; symptoms may include increased heart rate, shortness of breath, perspiration, chest pain, and nausea or diarrhea. Activation of the fight or flight response is also associated with the activation of numerous other responses [...]
Many Pregnant Women Take Drugs Harmful to Baby
Nov 30th
With the help of their doctors, women planning to become pregnant should take an inventory of the medications they take, researchers from Canada advise.
In a study, they found that many pregnant women still take medications long known to cause birth defects.
Some medications with known fetal risk, such as drugs that control epilepsy, are essential during pregnancy, Dr. Anick Berard, at the University of Montreal in Quebec, noted in an email correspondence to Reuters Health.
Other medications, such as those that treat severe acne, anxiety and psychiatric drugs, antibiotics, and many drugs prescribed for heart disease and medical conditions, "can and should be avoided," according to Berard.
Women should understand the side effects of any drug they are taking -- especially drugs treating a chronic condition -- and plan pregnancies to avoid or minimize risks such drugs pose to babies, Berard added.
For the 5 years between January 1998 and the last day of 2002, Berard and colleagues analyzed the prescriptions filled by pregnant women for drugs available at the time and known to pose fetal risks.
Their report, in BJOG: An International Journal of Obstetrics and Gynecology, shows 56 percent of 109,344 pregnant women filled at least one medication prescription. A total of 6.3 percent (6,871 women) did so for at least one medication known to pose a risk to the fetus.
"These pregnancies were associated with an elevated number of (pregnancy terminations) and babies born with major (birth defects) in comparison with the expected numbers in the population," they note.
Specifically, terminations occurred in 47 percent of the pregnancies exposed to drugs with known fetal risks. Six percent of these pregnancies ended in miscarriage.
By contrast, in the much larger non-exposed group about 36 percent of the pregnancies had been terminated and fewer than 5 percent ended in miscarriage.
Berard's team further identified birth defects in 8.2 percent of 2,842 infants exposed to risky drugs during gestation and available for assessment, compared with 7.1 percent of the 59,287 infants not exposed. This is "a statistically significant difference," they note.
They emphasize, however, that it cannot be concluded that the drug exposure caused the birth defects. These pregnancies may have also been exposed to other harmful agents or maternal health conditions, they point out.

Alcohol in Pregnancy has Variety of Possible Effects
Nov 23rd
A new study from Perth's Telethon Institute for Child Health Research has found evidence that the amount and timing of alcohol consumption in pregnancy affects child behavior in different ways.
The study has just been published online in the international journal Addiction.
Lead author Colleen O'Leary said the analysis was drawn from a random sample of more than 2000 mothers who completed a questionnaire three months after the baby's delivery, and were then followed up when the child was 2, 5 and 8 years of age.
"Mothers who reported what we would classify as heavy drinking in the first trimester of pregnancy were nearly three times as likely to report that their child suffered with anxiety and/or depression or somatic complaints," Ms O'Leary said.
“Those who drank moderately during that first trimester were twice as likely to report those types of behavioral issues for their child.
“Exposure to moderate or heavy levels of alcohol in late pregnancy increased the risk of aggressive types of behaviors in the child.
“This research suggests that both the timing and the intensity of alcohol exposure in the womb affect the type of behaviour problems expressed.”
In this study low levels of alcohol did not increase the risk of harm to the baby. However, the evidence clearly shows that the risk to the baby increases with increasing amounts consumed.
“It should also be noted that in this study moderate exposure is classified as drinking 3-4 standard drinks per occasion- that's about two normal glasses of wine-and no more than a bottle of wine drunk over a week.”
Heavy drinking included women who were drinking the equivalent of more than a bottle of wine per week.
“Not every child will be affected by prenatal exposure to alcohol. However it is important that women have this information about increased risk so that they can make informed decisions to give their child the best start to life,” Ms O'Leary said.
The National Health and Medical Research Council recommend that the safest choice for women who are pregnant or planning a pregnancy is to abstain from alcohol.
