Dr. Gellner: Juice, especially a 100% fruit juice is healthy. It's made with fruit. Sorry, that's outdated thinking. I'll address this old wives' tale and give you the updated scoop on today's Scope. I'm Dr. Cindy Gellner.

Announcer: Remember that one thing that one person told you that one time about what you should or shouldn't do with raising your kids? Find out if it's true, or not. This is Debunking Old Wives' Tales with Dr. Cindy Gellner on The Scope.

Dr. Gellner: I get asked this all the time. "How much juice can I give my baby, my toddler, my child?" Parents feel the need to give their child fruit juice. It's what they were raised on, so it's got to be good for their child. Right? A 100% fruit juice is healthy. Just like the fruit the juice was made from. Makes sense right? But that's wrong.

The bottom line is juice isn't all that healthy at all. In fact, unless I'm recommending it for constipation, I tell parents not to give babies under a year old any juice. For kids older than a year, I always say, "Drink juice in moderation. It's pure sugar and calories." In fact, store bought juice is nicknamed "liquid candy," just like soda is. Think about it.

Four ounces of lemon lime soda has 12.6 grams of sugar and 46 calories. Four ounces of apple juice has no fiber, 60 calories and 13 grams of sugar. Compare that to a 1/2 a cup of apple slices which has 1.5 grams of fiber, 30 calories and 5.5 grams of sugar. Big difference.

Real fruit has fiber, which makes it less likely to cause cavities and more helpful if constipation is an issue in older kids. Children need to learn how to eat fresh fruits and vegetables, not drink them. New guidelines for older kids are four ounces daily for children ages 1 to 3, 6 ounces daily for children ages 4 to 6, and only 8 ounces for children ages 6 to 18.

While some companies and organizations state that real fruit juice is a nutritious complement to whole fruit in balanced diets for older children, or even marketed as a way to add vitamin C and flavor variety to a baby's diet, the recent statement from the American Academy of Pediatrics states that juice has no essential role in healthy balanced diets of children. Studies also warn that infants currently drinking juice are more likely to want to drink soda and other sugar containing drinks when they get older.

Juice and other sugary drinks contribute to weight gain and tooth decay that we pediatricians see all the time in young children. By changing these guidelines and getting kids to cut down on juice, hopefully there will also be a decrease in cavities and obesity.

Interviewer: Vitamin D supplements. Dr. Kirtly Jones, do I need to take one?

Dr. Jones: That's a great question and it's debated hotly. Vitamin D is important. It helps your body absorb calcium for strong bones and it may help your micro biome so maybe your gut likes it. And there's some debate about your heart.

Foods that have it include milk, and eggs, and fish, and if you don't eat those things and you don't get outside or if you block up and cover up like your dermatologist said, you should take a supplement. The Institute of Medicine recommends 600 international units for young people and 800 for older people but not the 2,000, 4,000, 6,000, millions, whatever that you can get at the health food store. Or get out in the sun for about 20 minutes every day and your body will get all the vitamin D that you need.

Interviewer: A revolutionary new pacemaker, and we'll talk about it next on The Scope.

Announcer: Health tips, medical news, research and more for a happier, healthier life. From University of Utah Health Sciences, this is The Scope.

Scott: For about the past 50 years, at least since they were invented, pacemakers have basically been the same. But now there's a new option called a leadless pacemaker. It's really small, about the size of a large vitamin, and completely self-contained so it doesn't require wires or a surgical pocket like the old pacemakers did.

Dr. Roger Freedman is a cardiologist that specializes in implanting pacemakers in patients that require one. How do leadless pacemakers change things for patients that need pacemakers? First of all, it's so much smaller, that must be nice.

Dr. Freedman: Yes, Scott so as you say, ever since pacemakers were invented approximately 50 years ago, the design of pacemakers has been about the same. And that's consisted of what we call "the generator" which goes under the skin near the collarbone, which is connected to the heart, with one or two or three wires that travel from the collarbone area down to the heart through veins.

Interviewer: Yeah, and the generator was about the size of a silver dollar about a quarter inch thick?

Dr. Freedman: Yeah, they started out larger, and then most recently they've been the size of, I'd say, a large pocket watch.

Interviewer: Got it. But you had to make a little pocket in order for that to fit in and the surgical operation was a little bit more complicated as well, wasn't it?

Dr. Freedman: That's right. So there'd be an incision about an inch and a half long in that pocket under the skin for the generator to fit in.

Interviewer: Yeah, and then the wires would run down to the heart.

Dr. Freedman: That's right.

Interviewer: And this new version, the leadless pacemaker, they say it's the size of a large vitamin, and it doesn't have those wires, it just goes right by the heart?

Dr. Freedman: So the pacemaker, the new pacemaker, as you say, has no wires, and the entire pacemaker is about the size of a large vitamin pill and everything that was in the generator that we're familiar with, the battery, the electronics, the small computer, has now been miniaturized to the point where it fits into this vitamin capsule and that capsule gets delivered directly to the heart, so everything is self-contained within the heart.

Interviewer: And what size incision do you need to put this one in?

Dr. Freedman: There is no incision, so it's delivered through a catheter in leg up to the heart and once the pacemaker is attached to the inside of the heart he catheter comes out and there's no scar, there's no awkward sign that the patient even has a pacemaker.

Interviewer: Yeah, so the surgical procedure is non-existent really because there is no surgery, necessarily.

Dr. Freedman: I wouldn't even call it surgery.

Interviewer: Yeah, and it's so much smaller, how long does that battery last?

Dr. Freedman: So projections are that the battery would last 12 years, which is actually longer than conventional pacemakers last. And this is possible because the manufacturer has designed a very good connection between the pacemaker and the heart such the amount of electrical current required to pace the heart is less than conventional pacemakers.

Interviewer: So how does this change things for patients other than the surgery sounds a lot better, you don't have that surgical pocket anymore, that bump in your skin. What other advantages does a leadless pacemaker have?

Dr. Freedman: Conventional pacemakers don't have a high complication rate but there is a small incidence of complications including infection, including problems with the lead or leads, that connect the generator to the heart and because this newer pacemaker doesn't have a lot of those components a lot of the complications are totally avoided and it's been estimated that the complication rate of the newer pacemaker is going to be about half the complication of conventional pacemakers.

Interviewer: That's pretty incredible. Is everybody a candidate that would have normally got a regular pacemaker for the leadless pacemaker?

Dr. Freedman: Not yet. So right the now the leadless pacemaker is suitable only for patients who need really the simplest of pacemakers. Pacemakers that in their conventional design would only have require one lead, and that's about 10% of patients needing pacemakers. So it's still a minority of patients, but this is clearly the wave of the future and it's very exciting. I've been putting in pacemakers for decades and I would say this is the single most exciting breakthrough in all that time.

Interviewer: So I understand that not everybody can install, is that what you call it installing?

Dr. Freedman: Implant.

Interviewer: Can implant this type of a pacemaker, yet.

Dr. Freedman: Right, so actually, we are the only hospital in the state, in fact in the whole intermountain region that has access to this pacemaker. There's no other hospital in the city, in the state and even a five or six state area that has access to this pacemaker.

Interviewer: So at this point if somebody was interested in this leadless pacemaker option, they had the meeting with their cardiologist or doctor and they're not able to implant this type of . . . how would they get the new one then?

Dr. Freedman: Well they would call the cardiovascular division telephone number and we would see them initially for an office evaluation and make sure that they were an appropriate candidate for this kind of pacemaker. And then of course, we would talk to their own physician and make sure that he or she was agreeable and then we would proceed.

Interviewer: And why is it at this point that it's just available here in the state?

Dr. Freedman: So there's only a single manufacturer who has marketed this pacemaker and they're rolling it out very carefully only to selected sites, where they have the greatest confidence that it's going to be used properly. And in fact, I had to go Florida for a full day of training to implant this to make sure that it was done safely.

Interviewer: And how long of a procedure is this? Somebody comes in when are they leaving?

Dr. Freedman: Currently we're still keeping the patient for one overnight but I think in the future, once we have a little bit more experience we may discharge the patient on the same day.

Interviewer: All right. Is there anything else we should mention about this new technology? It sounds fantastic, it's like a picture of the future.

Dr. Freedman: Just that we're very excited about it and I would just tell patients that if they're having a pacemaker recommended and I think they might be a candidate for this, give us a call and we'd be happy to evaluate you.
