The battle to lose


Since the late 1970s, overweight and obesity rates in adults, teens, and children have soared, raising concerns about the impact on diabetes, heart disease, and cancer rates. This month's cover story is our effort to treat with humor a most serious problem.

The epidemic is most poignant in youngsters, but adults have to deal with it too. Losing weight--and keeping it off--isn't easy. Our culture conspires against dieters at every turn.

Tempting high-calorie foods at restaurants beckon us to overeat. Laborsaving devices-from telephones to automobiles--aren't going to disappear. And snack vending machines, ads extolling all-you-can-eat buffets, and home and work imperatives keep us off the bike path.

Then there are the factors we can't control, like our genes, our in utero environment, and perhaps contaminants in our air, water, and food that distort hormonal balances.

If we don't make the effort to lose (or avoid gaining) weight, it won't happen. But it also won't happen if we ignore the environment that undermines our efforts.

So, where to start?

* Restaurant meals. Those 1,000-calorie entrees, shakes, appetizers, and desserts are fattening us up. It is essential that we push for state and federal laws requiring calories on menus and menu boards at chain restaurants.

The first such law, in New York City, is not only spurring consumers to choose lower-calorie foods. It is prompting restaurants to lighten up their menus. With California and Boston passing laws and other jurisdictions considering them--and with KFC, Pizza Hut, and Taco Bell voluntarily listing calories on menus soon--I hope that 2009 is the year that Congress orders calories on menus nationwide.

* PE. Gym classes in schools are a natural, as are community bike paths, tennis courts, and swimming pools. What better way to pay for them than slapping small taxes (say, a nickel a drink) on belly-building soda pop?

* Schools. Getting junk foods out of schools and ads for junk foods off TV and other media aimed at kids is a no-brainer.

* Campaigns. The government should fund mass-media campaigns to encourage people to fill up on vegetables, fruits, and other healthy foods and to cut back on soft drinks, french fries, and other fattening foods.

* Breastfeeding. "Breastfed infants ... tend to gain less unnecessary weight and to be leaner. This may result in being less overweight later in life," says the government, which could mount campaigns to encourage moms to breastfeed for at least six months, maybe even offering bonuses to those who do.

I could go on, but those measures top my wish list. The challenge is to get beyond politicians' handwringing over "the terrible obesity problem" and to invest in the solutions.

Need urine from a catheter system? Forget the needle!


Learn how to reduce your risk of injury using a needleless device.

WANT A SUREFIRE way to eliminate the risk of a needle-stick injury while getting a urine sample from an indwelling catheter system? Don't use a needle. Besides protecting you from a needle-stick injury, the needleless system shown here, placed between the catheter and the drainage system, maintains the integrity and sterility of the catheter system by eliminating the need to puncture the tubing.
To obtain a sample using this needleless port, provide privacy for your patient. Gather clean gloves, a sterile luer-lock syringe large enough to hold the required sample, alcohol swabs, and an appropriate specimen container. Tell the patient what you'll be doing and why. Wash your hands, put on the gloves, and follow these steps.

1. Crimp or clamp the drainage tube at least 3 inches (7.5 cm) below the sampling port to let urine collect in the tubing. When you see urine under the access site, clean the sampling port with alcohol and let it air-dry.

2. Use aseptic technique to attach the uncapped syringe to the sampling port. Position it perpendicular to the center of the port, press the tip against the port, and twist gently to lock it in.

As shown, slowly withdraw the urine sample, then unscrew the syringe from the port. Transfer the sample into the specimen container and discard the syringe in an appropriate container.

3. Unclamp the drainage tube. Label the specimen container according to facility policy. Place the container in a biohazard bag for transport and send it to the lab as soon as possible.

Remove and discard your used gloves and wash your hands. Document the date and time you collected the specimen, the reason, the source (catheter), the amount and characteristics of the urine, the time you sent the specimen to the lab, and how the patient tolerated the procedure.
