There are many things to do to prepare for your baby’s birth. That’s why establishing a birth plan — a list of preferences for labor and delivery — may be in order.

The Nemours Foundation offers these suggestions about what to include in a birth plan:
Your ideal scenario for pain management, fetal monitoring, which family members to have in the delivery room, and preferred birth positions.
Your wishes for baby’s treatment immediately following birth, including cutting the cord, and when you get to hold and feed the baby.
Your plan for feeding — do you want to breast-feed or use formula?
Your plan for the baby’s hospital stay. Should baby stay with you as much as possible, or should baby stay in the nursery?
Your emergency plan, including preparations for possible premature delivery or Cesarean section.

Your ability to make sense of Groucho’s words and Harpo’s pantomimes in an old Marx Brothers movie takes place in the same regions of your brain, says new research funded by the National Institute on Deafness and Other Communication Disorders (NIDCD), one of the National Institutes of Health.

In a study published in this week’s Early Edition of Proceedings of the National Academy of Sciences (PNAS), researchers have shown that the brain regions that have long been recognized as a center in which spoken or written words are decoded are also important in interpreting wordless gestures. The findings suggest that these brain regions may play a much broader role in the interpretation of symbols than researchers have thought and, for this reason, could be the evolutionary starting point from which language originated.

“In babies, the ability to communicate through gestures precedes spoken language, and you can predict a child’s language skills based on the repertoire of his or her gestures during those early months,” said James F. Battey, Jr., M.D., Ph.D., director of the NIDCD. “These findings not only provide compelling evidence regarding where language may have come from, they help explain the interplay that exists between language and gesture as children develop their language skills.”

Scientists have known that sign language is largely processed in the same regions of the brain as spoken language. These regions include the inferior frontal gyrus, or Broca’s area, in the front left side of the brain, and the posterior temporal region, commonly referred to as Wernicke’s area, toward the back left side of the brain. It isn’t surprising that signed and spoken language activate the same brain regions, because sign language operates in the same way as spoken language does — with its own vocabulary and rules of grammar.

In this study, NIDCD researchers, in collaboration with scientists from Hofstra University School of Medicine, Hempstead, N.Y., and San Diego State University, wanted to find out if non-language-related gestures — the hand and body movements we use that convey meaning on their own, without having to be translated into specific words or phrases — are processed in the same regions of the brain as language is. Two types of gestures were considered for the study: pantomimes, which mimic objects or actions, such as unscrewing a jar or juggling balls, and emblems, which are commonly used in social interactions and which signify abstract, usually more emotionally charged concepts than pantomimes. Examples include a hand sweeping across the forehead to indicate “it’s hot in here!” or a finger to the lips to signify “be quiet.”

While inside a functional MRI machine, 20 healthy, English-speaking volunteers — nine males and 11 females — watched video clips of a person either acting out one of the two gesture types or voicing the phrases that the gestures represent. As controls, volunteers also watched clips of the person using meaningless gestures or speaking pseudowords that had been chopped up and randomly reorganized so the brain would not interpret them as language. Volunteers watched 60 video clips for each of the six stimuli, with the clips presented in 45-second time blocks at a rate of 15 clips per block. A mirror attached to the head enabled the volunteer to watch the video projected on the scanner room wall. The scientists then measured brain activity for each of the stimuli and looked for similarities and differences as well as any communication occurring between individual parts of the brain.

The researchers found that for the gesture and spoken language stimuli, the brain was highly activated in the inferior frontal and posterior temporal areas, the long-recognized language regions of the brain.

“If gesture and language were not processed by the same system, you’d have spoken language activating the inferior frontal and posterior temporal areas, and gestures activating other parts of the brain,” said Allen Braun, M.D., senior author on the paper, “But in fact we found virtual overlap.”

Current thinking in the study of language is that, like a smart search engine that pops up the most suitable Web site at the top of its search results, the posterior temporal region serves as a storehouse of words from which the inferior frontal gyrus selects the most appropriate match. The researchers suggest that, rather than being limited to deciphering words alone, these regions may be able to apply meaning to any incoming symbols, be they words, gestures, images, sounds, or objects. According to Dr. Braun, these regions also may present a clue into how language evolved.

“Our results fit a longstanding theory which says that the common ancestor of humans and apes communicated through meaningful gestures and, over time, the brain regions that processed gestures became adapted for using words,” he said. “If the theory is correct, our language areas may actually be the remnant of this ancient communication system, one that continues to process gesture as well as language in the human brain.”

The first-ever State Indicator Report on Fruits and Vegetables, 2009 provides information for each state on how many fruits and vegetables people are eating, and it highlights three key areas within communities and schools that can be improved to increase access, availability, and affordability of fruits and vegetables.
What does the State Indicator Report on Fruits and Vegetables, 2009 show?

The report shows that no state is meeting national goals for the amount of fruits and vegetables Americans should be eating. According to Healthy People 2010, a framework for the nation’s health priorities, the goal is for at least 75% of Americans to be eating at least 2 fruits daily and for 50% to be eating at least 3 vegetables daily. However, only 33% and 27% of adults are meeting these goals, respectively, and even lower proportions of adolescents in grades 9–12 are meeting them (32% and 13%, respectively).

Fruits and vegetables contain essential vitamins, minerals, and fiber that may help protect you from chronic diseases, including stroke, other cardiovascular diseases, and certain cancers. However, it can be difficult for many Americans to eat the recommended amounts of fruits and vegetables each day because they might not be easily accessible, available, or affordable.
Three key areas that can be improved

Retailers, such as supermarkets and grocery stores that stock a variety of high-quality fruits and vegetables, are an important asset for the health of residents.
Only 8 states have a state-level policy for healthier food retail improvements, which can help increase the number of full-service grocery stores in areas where they are unavailable, increase the availability of healthier foods in small food stores, and promote healthier foods through information at the point of purchase.

Schools are in a unique position to influence and promote fruit and vegetable intake among youth, school staff, parents, and other community members.
Only 1 in 5 (21%) middle and high schools offer fruits and non-fried vegetables in vending machines, school stores, or snack bars.
Only 21 states have a state-level policy for farm-to-school programs that can increase fruit and vegetable access in schools, as well as increase nutrition and agriculture knowledge among children in school.

Food policy councils, which are organized, multi-stakeholder organizations, support systems changes to improve food environments. A systems approach to food considers many factors involved in getting fruits and vegetables from farms to consumers, including the roles of growers, processors, and retailers.
Only 20 states have a state-level food policy council, and 59 local food policy councils exist across the nation.

Decades of steady progress against heart disease may be on the wane, experts say, with a new study showing that only 7.5 percent of Americans are now in the clear when it comes to heart disease risk factors.

The continuing U.S. obesity epidemic may bear much of the blame for the downturn, the researchers added.

“Our results raise the concern that a worsening cardiovascular risk profile in the population could potentially lead to increases in the incidence and prevalence of cardiovascular disease,” said lead researcher Dr. Earl S. Ford, from the U.S. Centers for Disease Control and Prevention. “Potential increases in cardiovascular disease and diabetes could affect the nation’s medical costs.”

Another expert agreed. Dr. Gregg C. Fonarow, a professor of cardiology at the University of California, Los Angeles, called the study “a wake-up call to the entire country to take more responsibility for their health by knowing their own cardiovascular risk factor profile and, in consultation with their physician, to take proactive steps to reduce their cardiovascular risk.”

The report is published in the Sept. 14 online edition of Circulation.

For the study, Ford’s team collected data on adults 25 to 74 years of age. They specifically looked for low-risk factors for heart disease — items such as not smoking, having low blood cholesterol, normal blood pressure, normal weight and no sign of diabetes.

Using data from the U.S. National Health and Nutrition Examination Surveys, Ford’s group found that in 1971 to 1975, a paltry 4.4 percent of adults had all five of these heart-healthy factors. However, by 1994 that number had risen to 10.5 percent of adults.

But the latest data, from 2004, found that the fraction of American adults with all five healthy characteristics had dropped to 7.5 percent.

Minorities tended to fare worst, since whites tended to have more low-risk factors than either blacks or Mexican-Americans, the report found.

Why the slide back in terms of heart health? Ford cited three reasons: “decreases in the percentages of adults who were not overweight or obese, who had a favorable blood pressure, and who did not have diabetes.”

There was one “bright spot,” however, a “decrease in the percentage of adults who were not currently smoking,” Ford said.

Because excess weight is a major cause of diabetes and hypertension, it is critical that the percentage of adults who are overweight or obese be reduced, the researcher said.

“To effect such change, the efforts of many will be required,” he said. “Furthermore, efforts at reducing smoking and improving nutritional practices to lower cholesterol concentrations in the U.S. population should be sustained. Clearly, there is a lot of room for improvement.”

Rob M. van Dam, an assistant professor of medicine at Harvard Medical School and author of an accompanying journal editorial, said that “the decline in cardiovascular disease mortality in the U.S. seems to be coming to an end and may even reverse because obesity and obesity-related conditions such as hypertension and type 2 diabetes are on the rise.”

“This alarming development is occurring despite great improvements in medical interventions to prevent cardiovascular diseases,” he said. “It is of particular concern that these trends do not yet reflect the consequences of the current epidemic of childhood obesity.”

Millions of Americans are now beginning their adult lives obese, van Dam noted. That could greatly increase their risk of chronic diseases and premature mortality.

“To fundamentally address this issue, population-wide initiatives are needed to prevent obesity,” he said.

Fonarow agreed. “If these trends continue, the recent gains in life expectancy in the U.S. will be lost,” he said.

Women who smoke while pregnant increase their unborn child’s long-term risk for health problems, including childhood asthma, cardiovascular disease and lower pulmonary function, and a new study may help experts understand why.

Researchers at the Keck School of Medicine of the University of Southern California (USC) found that maternal smoking actually changes the unborn child’s DNA patterns.

The new study found that fetal exposure to maternal smoking was linked to differences in DNA methylation, an epigenetic mechanism.

Epigenetics is the study of how chemicals that attach to DNA can switch genes on and off, which leads to differences in gene expression without changing basic genetic information, according to background information in a USC news release about the study.

While epigenetics plays a role in cancer research, little is known about how epigenetic changes may be caused by environmental exposures.

In the new study, the researchers used data from the USC Children’s Health Study, which examined respiratory health among children in 13 Southern California communities, as well as information from a questionnaire on maternal smoking exposure. The findings are reported in the September issue of the American Journal of Respiratory and Critical Care Medicine.

“This study provides some of the first evidence that in-utero environmental exposures such as tobacco smoke may be associated with epigenetic changes,” said one of the lead authors, Carrie Breton, assistant professor in the Department of Occupational and Environmental Health at the Keck School of Medicine of USC. “This could open up a new way for researchers to investigate biological mechanisms that might explain known health effects associated with maternal smoking,” she stated in the news release.

“Moms should not be smoking during pregnancy,” Linda Birnbaum, director of the U.S. National Institute of Environmental Health Sciences, said in the news release. “Maternal smoking during pregnancy is not only detrimental to the health of the mom and the newborn child, but research such as this suggests that it may impact the child into adulthood and possibly even future generations as well.”
