Look, Ma, no diaper!

Some local parents are embracing a technique for potty training infants

DOVER -- On a sunny weekday midmorning, Hannah Rothstein,4 months old, coos in her mother's lap at the kitchen table. Her older brother, Samuel, who is almost 3, plays in the backyard with a baby sitter. It's a typical suburban scene, except for one detail. Amid the accouterments of modern parenting -- bouncy seat on the floor, cellphone on the counter -- one kind of baby care basic is conspicuously absent.

This house has no Diaper Genie, no diaper pail, and no stack of diapers next to the changing table.

That's because no one in this house regularly wears diapers.

At the kitchen table, baby Hannah sits bare-bottomed on a tiny plastic potty that her mother holds while cradling her. Hannah is happily taking care of business while Melinda Rothstein talks to a guest.

Hannah was 4 days old when Rothstein first ''caught" her before she actually went to the bathroom, and Hannah has been going in a potty ever since. Rothstein sometimes lays out cloth diapers under her to sop up any ''accidents." And she uses little cloth training pants when they go out. Once in a while, she'll put on a disposable if they go to a restaurant. But, most days, Hannah is dressed in pint-size underwear. ''I wouldn't want to wear my toilet, would you?" says Rothstein, 31.

About a year and a half ago, Rothstein and a friend, Rachel Milgroom, started DiaperFreeBaby and DiaperFreeBaby.org, a nonprofit and a website dedicated to spreading the word about a technique called ''elimination communication," or infant potty training. About 70 people in the Boston area now belong to the group.

''Discover how amazing your baby really is," encourages the DiaperFreeBaby brochure. ''Just as parents learn to read their baby's signs for sleep and hunger, they can also learn to read their baby's signs for needing to eliminate."

Elimination communication has its roots in the traditional cultures of Africa and Asia, where mothers carry their babies close to them and hold them out to let them urinate on the ground. In suburban Boston, parents observe the child closely, taking cues from the child's body language and trying to get him to a potty, a toilet, or even a sink before he eliminates. A baby may start kicking or grimacing, or even stop nursing, just before the big event. And sometimes a parent can give the baby a cue, like holding her over a potty and making a ''sss" sound. Though most people agree it's easiest to start the process before the child is 6 months old, Rothstein says she started her older son at 8 months and it worked. Usually by 18 months children ''graduate," which means they know when they have to go the bathroom and they take themselves there.

Rothstein, like many of the mothers involved in the DiaperFreeBaby group, believes in an ''attachment" parenting style. Rothstein gave birth to Hannah at home. Hannah sleeps in her parents' bed and spends part of the day being carried around in a baby sling by her mother. This close contact allows Rothstein to better pick up on her baby's cues. Others are attracted to elimination communication because they worry about the environmental effects of using disposable diapers, and of washing loads of cloth diapers. Still others are simply trying to save money or avoid diaper rash.

''The first time I heard about it, I thought it was really weird," says Milgroom, who has two sons, Isaiah, 5, and Simon, 2. ''But the more I heard about it, the more I realized they do know when they need to go. How can I ignore that if I know he's telling me?"

Emily Jean Davidson, a pediatrician at Children's Hospital Boston, started elimination communication with her daughter, Betsy Resner, when she was 8 months old. Betsy, who is now 2, started wearing underwear in the daytime at 17 months, but still wears pull-up diapers at night.

''I try to compare it to other developmental tasks, like learning how to eat," says Davidson, who works with children with developmental disabilities. With eating, she says, parents watch for hunger cues and help children slowly develop independent skills over time. Why not do the same with toilet training?

In the first half of the 20th century, early toilet training was considered the norm, but it was regimented, even abusive. Children were strapped into potty chairs, or given soap suppositories when they wouldn't go on schedule. By the 1950s, Dr. Spock's more child-friendly methods became popular. But those old-fashioned cloth diapers were so uncomfortable when wet that most parents still toilet trained their children by 18 months. By the 1960s, pediatrician T. Berry Brazelton was advocating the ''child-led" approach. He advised parents not to pressure children but to let them proceed at their own pace until they could take control of their own toileting needs. Disposable diapers, which are absorbent and not as uncomfortable on the baby's bottom, made this easier. Procter & Gamble, maker of Pampers and Luvs, estimates that 95 to 99 percent of North American parents use disposable diapers.

That means children are taking longer to be toilet trained. According to a 2001 Medical College of Wisconsin study, the average was 35 months for girls and 39 months for boys.

Brazelton, who helped Pampers develop larger diapers for older kids, understands the impulse behind infant potty training but isn't convinced. ''To me, this is parents getting themselves trained and not leaving it to the child at all," said Brazelton, founder of the Brazelton Touchpoints Center at Children's Hospital Boston and one of the authors of ''Toilet Training: The Brazelton Way." Brazelton says he witnessed mothers holding their babies out from their bodies to urinate when he worked with Mayan Indians in southern Mexico. ''It's a regression to an earlier stage in our civilization," he says. ''I don't see it as progression. It seems like an unnecessary hovering of a parent over a child. I think there are more productive ways to interact with a child -- like play."

Laurie Boucke, author of ''Infant Potty Training" and ''Infant Potty Basics," says she understands the approach is not right for every family. ''If it resonates, give it a try," she says. ''And if it doesn't, don't do it."

At a recent meeting of the DiaperFreeBaby group, about 20 mothers, all toting infants and toddlers -- and, in some cases, potties -- gather at Milgroom's Newton home to discuss the basics of infant training.

''He pees like every 20 to 25 minutes," says one mother, Krysia Welin of Brookline, whose son, Kieran Hunter, is 10 weeks old. ''How do you pick it up each time and that quickly?"

Rothstein says, ''It's not all about catching it. It's more about communicating with your baby."

Emily Gelbert, also of Brookline, is expecting twins and hopes to practice elimination communication. Even in this group, people seem taken aback that she would attempt such a task with two children at once. They reassure her that sometimes using diapers -- even disposables -- is OK. Still, for these mothers, diaper-free is the key. Little Hannah Rothstein sits like a queen in the middle of the room on her tiny potty throne. Her mother explains that in the morning she goes every five minutes for about 20 minutes, after that, perhaps once an hour. At night, she usually goes only once.

''It's not more work," says Rothstein. ''Just a different kind of work."

Tour de France cyclists have big hearts

By MARIA CHENG, AP Medical Writer Mon Sep 3, 12:56 PM ET

VIENNA, Austria - Riding the grueling Tour de France bike race takes strength, stamina — and perhaps a heart nearly 40 percent bigger than normal.

Researchers who examined the hearts of former Tour bikers found that the athletes' hearts were from 20 to 40 percent larger than average, said Dr. Francois Carre of the Centre Hospitalier Universitaire de Rennes, France, speaking at a meeting of the European Society of Cardiology.

The difference is attributable largely to rigorous training that expands the cyclists' hearts. But researchers have not yet determined whether the athletes' hearts were larger to begin with.

"They are a special breed," said Dr. Richard Becker, a professor of medicine at Duke University and spokesman for the American Heart Association. Becker was not connected to Carre's study.

Scientists have long noticed the phenomenon of the "athlete's heart." Athletes who train hard in aerobic sports, such as cycling, running or swimming, tend to have a bigger heart that pumps more blood throughout the body.

The heart's walls become thicker to be able to handle the increased blood volume. That gives the athletes an edge by increasing their oxygen levels and improving their endurance.

Carre's study, funded by the Brittany provincial government in France, is perhaps the first to track what happens to athletes' hearts when they stop training.

Medical tests done on all Tour de France cyclists before the race begins showed virtually all have enlarged hearts, Carre said.

"When you see an athlete's heart test, you know right away that it's not a normal person," he said.

In his study, Carre tracked seven former professional cyclists through their final year of competition and three years of retirement.

Once a year, the cyclists took tests to check the size and function of the heart. They were also tested on their fitness levels.

Carre found that the athletes' hearts shrank nearly a quarter in size after they finished riding professionally. Still, the cyclists remained in excellent physical condition.

"Some athletes have a genetic predisposition to perform better," Carre said. "But we found that in these cyclists, their hearts adapted to the hard training conditions by just getting bigger."

The intense training that Tour de France athletes undergo to race in a three-week-long competition cycling up and down mountains is arguably among the toughest in professional sports.

"When you examine Tour de France athletes, they are probably among the best-trained athletes in the world," said Dr. Alfred Bove, a physician for the Philadelphia 76ers basketball team and vice president of the American College of Cardiology. "This study shows us that even in extreme conditions, the body finds a way to adapt."

Bove said that in athletes with bigger hearts, doping could prove potentially more dangerous than for normal people.

Athletes with bigger hearts have more red blood cells, which deliver oxygen around the body. These cells are thicker than normal cells. So if athletes decide to use an illegal agent like the blood-booster EPO, they run the risk of making their blood too thick. That puts them in danger of a clot, stroke, or heart attack.

"These athletes already have hearts that have increased in volume to adapt to their training workload," Bove said. "If they then go and use drugs, that could potentially erase the natural advantage they already have."

Study finds smokers have higher risk of dementia

1 hour, 33 minutes ago

WASHINGTON (Reuters) - People who smoke are more likely to develop Alzheimer's disease and other forms of dementia than people who have quit or have never smoked, Dutch researchers reported on Sunday.

Smokers over the age of 55 were 50 percent more likely to develop dementia than similar nonsmokers, Dr. Monique Breteler of Erasmus Medical Center in Rotterdam, Netherlands, and colleagues found.

Writing in the journal Neurology, Breteler and colleagues said they followed nearly 7,000 people age 55 and older for an average of seven years.

Over that time, 706 of the people developed dementia.

There is a well-known gene that raises the risk of dementia called APOE4 or apolipoprotein E4.

Smoking did not affect the Alzheimer's risk for people who had that gene. But people who did not have the gene had a 70 percent higher risk of Alzheimer's if they smoked.

Smoking could cause small strokes, which in turn damage the brain and cause dementia, Breteler said.

"Smoking increases the risk of cerebrovascular disease (stroke), which is also tied to dementia," Breteler said in a statement.

"Another mechanism could be through oxidative stress, which can damage cells in the blood vessels and lead to hardening of the arteries. Smokers experience greater oxidative stress than nonsmokers, and increased oxidative stress is also seen in Alzheimer's disease."

Oxidative stress is a process akin to rusting, in which chemical reactions damage the DNA.
