The study reiterated that drugs such as isotretinoin, thalidomide, Phenobarbital and valporate have been known to cause birth defects. However, little is known about the effects of the majority of prescription and over-the-counter drugs that are commonly taken during pregnancy. The study suggests it is impossible for pregnant women to know if medications they are taking pose a potential threat to the fetus. At the same time, information about birth defects and medications use may prompt some women to stop taking medications they need to treat a serious health condition.

The study was a collaboration between Boston University’s Slone Epidemiology Center, Harvard School of Publish Health and the Centers for Disease Control and Prevention. The researchers collected data from 1976 through 2008 with more than 30,000 interviews from women who reported their use of prescription and over-the-counter medications during pregnancy.

About 70 to 80 percent of women in the study said they had taken at least one medication during their first trimester, and about half of women reported taking at least one prescription medication during the first few months of pregnancy. The use of prescription drugs during the first trimester has increased over the last three decades by more than 60 percent, the study found. Antidepressant usage has increased dramatically, especially during the first trimester. The first trimester is believed to be the time when the risk of birth defects is greatest.

Depakote is a widely used anticonvulsant drug on the market, prescribed to women suffering from epilepsy and migraine headaches. A report entitled The Teratogenicity of Anticonvulsant Drugs done by the New England Journal of Medicine suggests a connection between Depakote use and the development of birth defects among infants exposed to the drug during pregnancy. The Food and Drug Administration supports these findings and published its own report Birth Defects Related to Depakote and Similar Drugs.

The report is a compilation of studies conducted on adverse effects of Depakote use during pregnancy. Among the birth defects found to be closely associated with the drug are severe and potentially fatal injuries and neural tube birth defects such as spina bifida. These birth defects have no cure and require life-long costly medical treatment. Sometimes extensive medical treatment is necessary to alleviate an infant’s symptoms associated with the condition.

In 2009, the FDA issued a warning about Depakote directed towards healthcare professionals and prescribing of the drug to women during pregnancy. The agency warned medical professionals and women of the increased risk of birth defects among infants exposed to the drug in the uterus including malformed face and skull, spina bifida, spinal cord defects, and cardiovascular malformations.

The biggest rise was seen in calcium. Two thirds of women 60 and older are taking calcium each day, up 28 percent since 1990. Baby boomers may be contributing to these figures, experts say. Many women have also been encouraged to take calcium to protect against female health issues during menopause including osteoporosis.

Federal officials conducted surveys in 1988-1994 and 2003-2008 and asked participants to list what supplements they took. Data collectors also asked to see the bottles for verification purposes. Use of multivitamins was the most popular, up 40 percent since the last survey.

The survey found that most people who take vitamins and dietary supplements are well educated and have good incomes, and most eat well and receive healthy amounts of nutrients from their diets. Some argue that individuals taking supplements do not really need them, while the rest of the population who needs additional nutrition due to poor diets skips the essential vitamins. Federal surveys have recently started asking why people take supplements, with many reporting taking supplements due to pregnancy, folic acid for women thinking about conceiving, and calcium for older women to prevent osteoporosis.

Dr. Bryan Michalowicz, a dentists at the University of Minnesota School of Dentistry in Minneapolis and his colleagues tested more than 400 two-year olds who had been born to mothers with gum disease. Half the mothers had been treated with aggressive cleaning including scaling and planing during pregnancy, while the rest had not. The researchers found that kids did just as well on language, motor and mental tests regardless of whether their mothers had received gum disease treatment while pregnant. The treatment did not seem to cause any developmental delays, as previously feared.

It is important for women to maintain good oral health. However, pregnant women are more susceptible to gum disease due to hormonal changes. The standard antibiotic treatment is not recommended because it stains the baby’s teeth. Previously, it has been feared that aggressive treatment may cause brain development issues of the fetus. Gum disease is caused by a bacterial infection that breaks down gum tissue and can cause serious health problems including tooth loss.

The study examined 1,235 children born to mothers with epilepsy between 1973 and 1986. Children of mothers who were only taking a single medication did not seem to be as effected and were able to complete school just like their peers, although they were less likely to pass classes with excellence.

Doctors not involved with the study claim it is important for mothers to know that they are able to have normal kids. Childbearing is an important consideration for women with epilepsy, as drugs may have an effect on fetus development. Besides drugs, seizure can injure the fetus, and a woman with epilepsy cannot be off medication completely.

Epilepsy is a chronic neurological disorder characterized by recurrent seizures that may be brief muscle jerks or severe and prolonged convulsions. Anticonvulsant drugs are most commonly prescribed to treat epilepsy, with about 20 drugs available on the market right now. Most anticonvulsant drugs have side effects such as dizziness and fatigue, but some carry a higher risk of suicidal acts.

A different study found that women with epilepsy may have an increased risk of infertility due to taking multiple anti-seizure medications.

Researchers at the U.S. Centers for Disease Control and Prevention found that the extent which the rise reflects a true elevation in women is unclear. Chronic medical conditions are exacerbated by pregnancy, including heart disease. Deaths from actual birth such as hemorrhaging are declining. Even high blood pressure that may occur during pregnancy appears to be declining in rates. Another factor is reporting of deaths, as a new cause coding system was implemented in 1999 and a system before it did not have a pregnancy or maternal checkbox.

For the study, the researchers looked at data on 4,693 pregnancy-related deaths reported to the agency between 1998 and 2005. A pregnancy-related death is any death occurring during or within one year of pregnancy that was attributed to pregnancy complications.

The new findings do not underscore the importance of women’s health before and during pregnancy. A lead researcher of CDC’s division of reproductive health suggests that all women should try to have a pre-pregnancy visit with their doctor and get any health issues under control before becoming pregnant. Doctors warn that our society sees more obese women in of childbearing age which raises the risk of diabetes and high blood pressure.

The lead researcher Dr. Damini Jawaheer said that women who are trying to become pregnant are often told to stop using disease-modifying anti-rheumatic drugs such as methotrexate and infliximab as some can cause birth defects. The research team said it is unclear if the condition or stopping medication causes a flare-up in rheumatoid arthritis that somehow hinders a woman’s ability to conceive.

In general, women with rheumatoid arthritis take longer to conceive and are less likely to get pregnant within 2 months of trying. During the study, 48 percent of women without RA conceived within 2 months of trying, while women with RA had a lower percentage of a successful conception within 2 months of trying. When the researchers took into account age, body weight and other factors, women with RA were more likely to need more than a year to conceive.

Rheumatoid arthritis (RA) is an auto-immune disease occurring when the immune system mistakenly attacks tissue in the joints, leading to inflammation, pain and progressive joint damage. The disease is more common in women than men.

Out of 105 first-time moms, two-thirds ended up requesting epidural pain medication during labor compared to 56 percent of women who received a placebo version of the procedure and 77 percent of those given no acupuncture treatment at all.

This study followed two research studies in South Korea and the UK, which analyzed 10 previous clinical trials of acupuncture for labor pain and found no evidence that the procedure eases pain during birthing.

The lead researcher on the current study said that he believed overwhelming research done by different groups suggests that acupuncture offers little benefit to women in labor.

Acupuncture has been used for more than 2,000 years in Chinese medicine to treat a variety of ailments. Specific acupuncture points on the skin are connected to internal pathways that conduct energy. Stimulating these points provides a healthier flow of energy and releases pain by altering signals among nerve cells.

For the current study, out of 105 women 52 were randomly selected to have acupuncture before a painful contraction. In the end, both acupuncture and placebo acupuncture groups showed no difference in the need for pain medication during labor.

Iron is essential to making hemoglobin, the component of red blood cells that carries oxygen throughout the body. A pregnant woman’s iron needs rise as her body produces greater volumes of blood for her and the fetus. A professor of human nutrition at Cornell University said that the gut senses when the body needs iron, and through gut responses the body absorbs iron better.

According to the World Health Organization, fewer than one in five pregnant women in the U.S. were anemic in 2005. In other countries, those statistics may be as high as up to 57 percent of pregnant anemic women.

A team of researchers from U.S. and Belgium recruited 1,270 pregnant women. About 550 of them were anemic at the beginning of the trial. Half the women took supplements with 60 milligrams of iron and 400 micrograms of folic acid. The other half took 30 milligrams of iron and 400 micrograms of folic acid. Both groups took vitamins including zinc, Vitamin A and C.

The research group found that women who were anemic at the beginning of the study caught up to those women who were not anemic, their levels of iron in the blood ended up the same at around 11 grams per deciliter.

Other research groups in Cyprus, Greece and England conducted blind tests in which they were able to correctly identify 14 cases of Down syndrome through a blood test and 26 normal fetuses.

Down syndrome results in cognitive delays and is a chromosomal condition caused by the presence of all or part of an extra 21st chromosome . Currently, a pregnant woman must go through blood tests and ultrasound to find out if the fetus is at risk for Down syndrome. The condition is estimated at 1 in 733 births. An additional test of collecting a sample of amniotic fluid or the placenta is necessary for a firm diagnosis. Taking a sample of amniotic fluid carries its own risk such as fetal injury and miscarriage. Having a reliable blood test for Down syndrome could eliminative the invasive procedure and lessen the risk of miscarriage.

Scientists in other studies have reported that analyzing the mother’s blood could detect Down syndrome in a fetus without having to collect amniotic fluid samples. No commercial test exists yet but at least one company is hoping to introduce it in the U.S. within a year.
