members don't always take well to changes, but what started out as outrage on twitter turned to excitement. the response may be a good sign after separate studies found two-thirds of users have taken breaks for weeks at a time, and become more sensitive about who sees their information. despite having more than 600 million active users, the company has only lost value since going public. facebook debuted in may at $38 a share. tumbled almost immediately, and hasn't fully recovered. compare that to linkedin, which has almost doubled in value since its debut. >> i think it caught investors by surprise to think that facebook didn't necessarily have a clear monetization path when they went public, not just in terms of advertising but also the payment side, virtual goods and so forth. >> reporter: founder mark zuckerberg says recent numbers have been better than expected and is confident about expanding facebook's audience. but one of the company's biggest challenges has been how to make money off its mobile users, a

group growing by the hour. just last month, the number of people checking facebook on mobile devices topped the number checking the site on the web. >> i think it's important for them to be able to sort of, you know, evolve the experience from something where they're trying to push and create demand to one where they're trying to satisfy demand for their existing user base. >> reporter: revenue concerns aside, facebook still has a lot going for it. it's unique, it's ubiquitous and it's only nine years old. alison kosik, cnn, new york. >> wow. that's incredible. just nine years old. that's going to do it for me. i'm fredricka whitfield. don lemon at the top of the hour. first, rescuing the american health care system. "sanjay gupta, m.d." starts right now. >> hi there and thanks for watching. i've got a story that parents and grandparents need to hear. some daycare workers will be breaking the law if they use a very common technique to put babies to sleep.

i've used this technique myself for all three of my kids. also, the epidemic of drug abuse with prescription pain meds. there is a voice we often don't get to hear of children. and you're going to meet an 89-year-old woman who is completely blind and she has this amazing story about how she was able to travel the world still. let's get started. ♪ first up, a new documentary that takes a hard look at my profession. medicine. it's called the escapefire and makes a controversial case. it says doctors focus too much on money, do unnecessary procedures, don't spend enough time on basic prevention. case in point, a patient named de von, diagnosed in her 30s with heart disease who had bypass surgery 27 cardiac catheterizations and stents to keep her blood vessels open.

then she ended up at the cleveland clinic where doctors got her cholesterol and blood pressure under control and they say counseling and diet and exercise helped yvonne lose 20 pounds to try and avert more surgery. >> i can't tell you how shocked we were when we saw her the first time. because here was a young woman whose diabetes was not well controlled, her cholesterol was never well controlled and her high blood pressure was never well controlled. if someone had talked to her, i think someone had really -- teased out her chest pain and shortness of breath, many of her stents would not have been necessary. >> earlier i spoke with dr. steven nicen, featured in the film. and also with dr. jeffrey marshal, a leading cardiologist whose specialty is implanting stents. >> doctor, let me start with you. you say there is a lot of yvonnes out there, the patient we just met. a lot of unnecessary stents. you say they don't prevent heart

attacks, they don't lengthen life. >> the problem is, if you have stable chest pain, we have very good studies dating back a number of years that show that getting a stent will not prevent a heart attack and will not make you live longer. these are techniques that should be used to relieve symptoms. and some people even that are getting stents don't have symptoms. they have a blockage not causing symptoms, and yet they're actually having a procedure. >> are a lot of these stents unnecessary? >> i don't believe so. actually, about 70% of all angie owe plasty and stent procedures in this country are done in people actively having heart attacks, okay? large heart attacks or kind of smaller heart attacks or having what we call unstable an jina, chest pain that is currently damaging the heart in patients. so less than 30% are actually done in these people with stable schemic heart disease. >> we're 50% more likely to have

a stent than in western europe where they have similar disease rates. more likely to have a knee replacement or cat scan or mri. and that's because our system reimburses people for doing tests and doing procedures. not for necessarily making people healthier. >> i think what doctor nicen is describing is a fee for service sort of model. you get paid for the service you're doing as opposed for the overall care of the patient. this is what you do for a living. is that how you get paid? so if you have a patient who comes in, you get paid a certain amount because you do a stent. are you incentivized to do more stents? >> well, me personally, i'm on a salary. >> it doesn't matter. >> it doesn't matter if i do one stent or five stents or ten stents. my job oh is to provide the right care for the right patient at the right time. >> so you're salaried. >> yes, sir. >> i'm salaried too as a physician. and doctor, you're salaried, as well. how big a problem is it, then, these perverse incentives. >> we're not saying people are doing these procedures for

profit. we're saying that the system has created incentives that in subtle and maybe not so subtle ways drives more procedures. if you get a bump on your head, as a friend of mine had, and you go into the emergency department in america, you get a cat scan. if you have that happen in germany or in england, they say here's a list of instructions. if you have problems, come back and see us. we just spent $1,000. >> sometimes the patients demand this stuff. >> yes. but we have to educate patients. >> i want to point out something. i think this is important. because i think when people watch the film, they're left with the impression that yvonne finally came to the cleveland clinic, she got her cholesterol under control, her weight under control, and things were great for her after that. but that's not the whole story. she ended up having another open heart operation. another bypass operation. i think that's an important point. it doesn't always work. i mean, the impression i think was a little bit mislead there. don't you think? >> i do. look, we can't prevent disease in everybody.

but we have to try. the problem with yvonne's case is she had all of those stents before she had had the risk factors controlled. that's not good medicine. we have to teach young physicians that prevention comes first. >> in the spirit of educating people out there, i have cardiac disease in my family, who should actually get a stent? >> anybody having a heart attack should get a stent. it's the best treatment and saves lives. period. everybody agrees on that. the next group of people are people really that have tried medical therapy, that are on medical therapy and they're failing. there are lots of people like that. >> and you can see escape fire in its entirety followed by the rest of my discussion on rescuing the american health care system. that's sunday night, 8:00 p.m. eastern right here on cnn. come up, orphaned by prescription drugs. i'm going to take you to this town where parents are scarce. a place the kids are calling a new normal. what's next?

you've probably heard me talk a lot about prescription drug overdoses. reason being that it's an epidemic. it kills another person every 19 minutes. it can happen much more easily than you think. what we don't hear enough is the story of people left behind. and far too often, it's the kids. if this town could talk, it would describe a simple, idyllic life. a proud people. it would also whisper a sobering story. about an epidemic that is tearing apart family -- >> i lost my dad and my uncle to drug abuse. >> after family. >> i've lost both my uncle and my cousin to years of prescription drug abuse. >> after family. >> i lost both my mother and my

grandmother to oxycontin. >> it is not uncommon to hear stories like these echoing down the hallways, every day, at this high school in rock castle county, kentucky. >> you're constantly hearing of someone else that is dying because of abusing prescription drugs. ♪ >> 16-year-old avery broad shaw knows this story all too well. >> my grandpa, he just set me down and told me that he was gone. >> when avery was just 7, his father overdosed on oxycontin. he says his mother was in and out of his life. >> the hardest part growing up without a dad would be not having that model family that you always see. >> he's lucky enough to live with his great grandparents. in this town, that model family is being redefined. >> there's got to be plenty more in this school that's -- had the same thing happen to them. it's a terrible thing.

>> a terrible thing that 17-year-old junior sean watkins saw firsthand. >> we went in her room, and she was face-down on the bed. >> when he was 10, sean walked in on a terrifying scene in his mother's bedroom. she was dead. after overdosing on pain killers, oxycontin. >> i thought it was -- it was awful. my mother died. but i couldn't understand the gravity of the situation. i didn't understand that my mom was gone forever. i was going to see her again. >> sean had known for years that his mom was in trouble. >> my mother started off, you know, with back pain, started off just taking pills for that. and eventually it got worse. and developed into other drugs. >> a prescription drug for back pain leads to dependence and eventually an overdose. >> this is happening in rockcastle county every week. but it's happening in eastern kentucky every day.

it's leaving our communities in shreds. and we're left behind to pick up the pieces from that. >> karen kelly is the executive director of operation unite, a community coalition devoted to preventing overdose deaths in kentucky. in fact, kentucky is the fourth most medicated state in the nation. and it has the sixth highest rate of overdose deaths. in one county alone -- >> half of the kids have no parent in the home whatsoever. so now we're seeing many raised by great grandparents, because we've lost an entire generation of young people. and, you know, the kids are really the ones paying the biggest price. >> we were just sick and tired of going to funerals. we were sick and tired of having kids come in and not being able to sit through physics class because they were worried about mom who had overdosed or dad had been arrested. >> nancy hale worked in the rockcastle county school system for 34 years.

>> so we were like, what can we do, how can we help these families? >> so hale and other teachers decided to start a club at the school. where kids could learn and teach others about drug prevention. >> it really helps a lot of kids that are going through those problems to know that they're not alone. >> but sean says the pain of growing up alone never goes away. >> it's tough, you know. you've got somebody else's house and they've got a loving mom and dad and yours are -- yours are gone. >> and this terrible new normal isn't just in kentucky. in fact, nationwide, more than 4% of all children don't live with their parents. that number has more than doubled in the past 20 years. addiction like you just saw there is a big reason. a legal fight over the best way to help babies stop crying and go to sleep. everybody wants to learn more about this. so dr. harvey carp is going to stop by to show us. i tried weig. but their shakes aren't always made for people with diabetes.

we are back with sgmd. got milk. here's a question. which kind. you've probably noticed a lot more variety in the dairy section lately and a lot isn't dairy at all. you need to know this, because just because it looks like cow milk doesn't mean it necessarily has the same nutrients. let me go through this. rice milk, for example, is a good option in baked goods but not to replace dairy milk because it contains virtually no calcium or protein. there's coconut milk, as well. that contains some of the good,

quote, unquote, coconut fat, low in carbs but also low in protein and calcium. the unsweetened kind is an okay option for people lactose intolerant or have dairy allergies. my favorite as far as milk alternatives go is almond milk. it contains the same amount of calcium as cow's milk has more vitamin e. plus, get this, lower in calories and in fat. almond milk tastes good, as well. creamy taste, good with oatmeal, smoothies or in cereal. okay. time to talk about a trick that i learned pretty quickly when i first became a dad. sw swaddling. it can help your baby from crying, encourage better sleep. but some people now say it's also dangerous. and in a handful of places it's been banned. so we decided to call the authority on all things baby and sleep related. dr. harvey carp, author of "the happiest baby guide to great sleep," a big proponent of swaddling. you have a dvd that shows these

techniques, specifically. thanks for joining us. >> thank you, sanjay. >> we got a lot of comments when you joined the show and i think it's because so many people deal with the issues you talk about. swaddling. you learned it in the hospital. i did. i was actually champion swadler for a while in our family. >> oh, you were. >> i don't know how my wife feels about that comment. talk about swaddling, first. why is it effective? >> well, the baby is in the womb for nine months. this is how much room they have. they're not expecting to be in a world where they can have, you know, full use of their arms. as a matter of fact, the world is too big for them. so babies don't need freedom. they need security. swaddling is the key to keeping a baby happy and calm. because it promotes sleep -- lots of studies show that. and it reduces crying. >> the concern -- i read some of the same stories that you did, i'm sure, about people being concerned about it now. even banning it. saying it may be more likely to be associated with sids, maybe more likely to be associated with problems of the hips. what was your reaction when you first heard that? >> it's just totally

wrong-headed. i mean, i don't want to be dismissive of my colleagues, of course. but if you look at the studies on the hips, for example, all the swaddle studies that show it's a hip problem were done in primitive cultures, with a totally different type of swaddling. as long as the babies can move their legs a little bit, it's perfectly fine for the hips, and even the biggest center here, the international hip dysplasia institute of the united states recommends swaddling. and for sids, it probably reduces the risk of sids and suffocati suffocation, because if you don't swaddle your baby, they tend to flail and wake up. and that's what items parents to bring the baby in bed with them or put the baby to sleep on the stomach. and a study was just done last year that shows if you swaddle your baby, you're twice as likely to put your baby in the safe position. so swaddling actuallily increases safety, doesn't decrease it. >> you have a dvd out. let's look at this ourselves here. and i'll tell you flat out. my youngest is 3 now so it's been a little bit of time.

how long for you? >> mine is 29. but i swaddled a baby yesterday. so i'm a lot more on key. >> okay. i'll point out, we have a couple dolls here and blankets. these are fancy blankets. we didn't have these when i had my youngest. you want to talk us through this. >> yeah. here's a swaddle baby. i personally just use a big square piece of fabric. i'm kind of old school. you fold -- hold like a diamond. but you have to be snug with the arms but allowing the legs to be able to flex and move. so -- >> that's that hip dysplasia thing. don't want to cause that. >> this is super easy, put the feet in the bag and then bring over part of the wrap. but look what you do. you tuck it and snug it. those arms have to be snug. if they pop out, the kids smack themselves in the face and get more upset.

and then you -- and then you close it with these little velcro tabs. but i've got to tell you one thing with swaddling. most babies cry more when you swaddle them, which makes parents lose confidence. the key to successful baby calming is swaddling plus the next things that you do. and the next things are to then roll the baby on the side or stomach. do the shhh-ing or the white noise you can use all night long with the babies. and some babies even need a little bit of jiggly motion. because they're kind of like bouncing baby boys. they kind of need that kind of action. >> i used to do that all of the time. my wife would literally say that's not how you do it and it's funny, because it worked. i called it the football pose. >> there you go. >> kind of like a football. but it worked. always enjoyable to have you here. >> thank you. thank you very much. >> on behalf of a lot of parents, thank you, as well. >> thanks for your time. still ahead, we'll see the world through the eyes of a woman who has been blind for half her life.
