The controversy over Bisphenol A, or BPA, continues, as heated as it was in 2008, when reports about possible health consequences to humans from long-term exposure followed reviews of many scientific studies.
What Is BPA?
BPA is a solid, colorless chemical used to make many kinds of plastics, and to make the sealant or liner on the inside of food and beverage cans. BPA is used to harden plastics, though it’s also found in some plastic sandwich bags and plastic cling wrap.

New federal recommendations in the United States are for all pregnant women to be screened for gestational diabetes at 24 weeks of pregnancy, even when they have no symptoms of the condition.
The new guidelines from the U.S. Preventive Services Task Force (USPSTF), published in the Annals of Internal Medicine, are now the same as those of other medical organizations, including the American Diabetes Association (ADA) and the American College of Obstetricians and Gynecologists (ACOG).

A Chinese study has found that breastfeeding may be linked to lower risk of rheumatoid arthritis in women who nursed their infants.
The study reviewed data from more than 7,300 women aged 50 and older from China, who filled out questionnaires asking about their health and lifestyles, including whether they had breastfed their children. Most of the women had at least one child, and more than 95 percent of moms had breastfed for at least one month.

Women who are hospitalized during pregnancy for reasons other than to give birth have a much greater risk for venous thromboembolism (VTE) during and after their hospital stay, according to a new study. Clot risk was also higher in the 28 days following discharge from the hospital. The risk was especially high for women hospitalized for three or more days, women older than 35, and in the third trimester of pregnancy.
The study, published recently on bmj.com, found that hospitalized women in the above groups had 17.5 times the risk of developing the potentially deadly clots, compared to women who were not hospitalized.

Mistakes by medical staff are usually to blame in cases where a baby suffers a lack of oxygen at birth, according to a new study from Norway.
Birth asphyxiation, or hypoxia, happens when a baby does not get enough oxygen before, during or right after birth. Oxygen deprivaton can result in brain damage, mental disabilities, cerebral palsy, epilepsy or even death to the infant.

The importance of breastfeeding and of introducing solid foods later for preventing food allergies in children has become clearer to health professionals in recent years. Now, a new British study has found that waiting until at least 17 weeks of age to introduce solid foods helps infants avoid food allergies later on. That same study found that babies were more likely to be immune to food allergies if they were also being breastfed when solids were introduced at 17 weeks or later.
Overlapping the start of solid foods with breastfeeding seems to teach the baby’s immune system that solid foods are safe; or it could be that the mother’s breast milk provides the right types and numbers of cells and organisms that will strengthen the baby’s immunity, thereby preventing the infant’s body from developing allergies to different foods.

Recently published results of a global study examining pre-term births reveal that male babies face greater risks while growing inside the womb, at birth and after birth.
The study, which was funded by the Bill & Melinda Gates Foundation, examined more than 15 million babies born prematurely worldwide. It found that boys have a 14 percent greater chance of being born prematurely than girls; preterm boys also have a higher risk of disability and death than preterm girls.

Current medical practice in the United States is to give babies their first measles shot between 12 and 15 months, while in Canada, that measles shot is given at 12 months. But a new study out of Quebec shows that waiting until 15 months offers children better immunity against the measles later on.
In a recent large measles outbreak in Quebec, students who had gotten their first measles shot at 12 months were found to be about six times more likely to come down with the measles than those who had gotten their first vaccination later.

Good oral health is an important part of our general health. But researchers have found that an expectant mother’s oral health also has the potential to affect her unborn infant’s health. Bacteria from the mother’s mouth can get into the mother’s blood, from where it reaches the amniotic fluid that surrounds the baby, and the baby can then swallow the bacteria.
Studies have shown that these oral bacteria can increase the risk of a premature birth or a low-birth-weight baby, start contractions prematurely, or cause the baby to get an infection — either as a newborn, or while the infant is still inside the uterus.

Using 4-D scans, psychologists have uncovered that a baby learns to open its mouth in preparation for putting a hand in the mouth several weeks before full gestation.
Researchers from Durham and Lancaster universities in England performed 60 scans of 15 healthy fetuses at monthly intervals, between 24 and 36 weeks of pregnancy. The youngest fetuses were more likely to touch the upper part and sides of their heads. But as the fetuses got older, they began to more often touch the lower part of their faces, including the mouth; the lower part of the face is the more sensitive part. By 36 weeks, a greater number of the babies began opening their mouths before touching them, suggesting that they were able to anticipate that they were about to touch their mouths. Younger fetuses tended to open their mouths after having placed their hand on it, meaning that they were responding to the touch.
