Some Medicare Advantage Plans Raising Hospital, Nursing Care Copays

THURSDAY, June 11, 2015 (HealthDay News) — Millions of older Americans with Medicare Advantage plans face large out-of-pocket costs for hospital stays and skilled nursing care, according to new research.

“Policymakers are very concerned about how much Medicare beneficiaries need to spend for essential medical services,” study corresponding author Dr. Amal Trivedi, an associate professor of public health at Brown University in Providence, R.I., said in a university news release

“It’s one of the goals of insurance — to protect people from large, catastrophic out-of-pocket expenses,” Trivedi said.

Researchers reviewed the records of more than 8 million Medicare Advantage enrollees. The study participants took part in more than 1,800 different Medicare Advantage plans. The researchers looked at the pricing structures of their plans before and after federal policy changes took effect in 2011. These changes were designed to help protect consumers.

The changes restricted some copays, or cost-sharing. They also imposed a limit of $6,700 on total out-of-pocket costs for Medicare Advantage plans. Plans that agreed to an even lower cap of $3,400 had more flexibility in how they could overhaul their cost-sharing. Traditional Medicare has no cap on out-of-pocket expenses, according to the researchers.

Researchers calculated what the average American would have to pay for hospital stays and skilled nursing care based on their plan.

Following the policy change, fewer than one-third of Medicare Advantage members in low premium plans that already had an out-of-pocket limit faced higher copays for hospital or skilled nursing care. More than one-third had a reduction in copays, the researchers noted.

But among those covered by plans with new out-of-pocket caps, however, 55 percent had increased copays for hospital stays and 46 percent had higher copays for skilled nursing. Fewer than one in six of members in plans with new out-of-pocket limits had lower cost-sharing.

On average in 2011, older people with lower premiums under Medicare Advantage plans were expected to pay $1,785 for a week in the hospital and about three weeks in a skilled nursing facility. The researchers noted these services are common occurrences following serious health issues, such as a stroke, congestive heart failure or a broken hip.

Even those who paid higher monthly premiums faced an average copay of $1,446, the study found.

Those who received federal subsidies because their incomes fall below a certain threshold faced the same high copays for Medicare Advantage plans, the researchers noted.

“For low-income beneficiaries, these copayments for inpatient and skilled nursing care could be more than a month’s worth of income,” said study author Laura Keohane, a Brown doctoral student, in a university news release.

By comparison, someone with traditional Medicare would pay $1,132 for those services, along with physician copayments for services received in the hospital.

“The perception out there is that Medicare Advantage offers more generous benefits than traditional Medicare without supplemental coverage, but for long inpatient stays and long stays in a skilled nursing facility, that’s generally not the case, we found,” Trivedi said.

Medicare Advantage copays were lower than those of traditional Medicare for shorter hospital stays, the researchers pointed out. The average costs for a three-day admission were $544 for low-premium plans and $511 for those with higher premiums.

The researchers concluded the overall cap on out-of-pocket costs issued in 2011 may have caused many plans to increase copays for hospital and skilled nursing care. As a result, older people in poor health facing higher copays for hospitalization may be discouraged from enrolling in some Medicare Advantage plans.

The study authors said policymakers should determine if more needs to be done to protect Medicare Advantage consumers, particularly low-income seniors, from high out-of-pocket costs for unpredictable medical problems that require long hospital stays and skilled nursing care.

The study was published in the June issue of Health Affairs.

RIP Sir Christopher Lee 1922 - 2015

 RIP Sir Christopher Lee 1922 - 2015

RIP Sir Christopher Lee, known as the master of horror, has died at
the age of 93 after being hospitalised for respiratory problems and
heart failure.
The veteran actor, immortalised in films from Dracula
to The Wicker Man, and via James Bond villainy to the Lord of the Rings
trilogy, died at 8.30am on Sunday morning at Chelsea and Westminster
Hospital in London.

His wife, the former Danish model Birgit
Kroencke, decided to hold back the information for four days until all
family members and friends were informed. The couple had been married
for more than 50 years and had one daughter, Christina.
The actor was knighted in 2009 for services to drama and charity, and was awarded the Bafta fellowship in 2011.

News
of his death prompted an outpouring of grief from actors, musicians,
and even the prime minister; all paid tribute to Lee’s great talent.

Tim Burton, the director who worked with Lee on five films, described him as “a true legend”.

“Christopher
has been an enormous inspiration to me my entire life. I had the honour
and pleasure to work with him on five films (Sleepy Hollow, Charlie And
The Chocolate Factory, Corpse Bride, Alice In Wonderland and Dark
Shadows),” he said.

“He was the last of his kind - a true legend -
who I’m fortunate to have called a friend. He will continue to inspire
me and I’m sure countless others for generations to come.”

Leading
the tributes online were his Lord of the Rings co-stars Dominic
Monaghan and Elijah Wood, as well as Sir Roger Moore, who played 007
opposite Lee in The Man With The Golden Gun.

Singer Carrie Underwood hit the CMT Awards last night—and while the 32-year-old’s on-stage performance definitely turned heads, even more people took note of the slim figure the Grammy Award-winner showed off on the red carpet…just four months after giving birth to her baby boy, Isaiah Michael Fisher. With a body bounce-back like that, it is clear that Underwood is no stranger to working out.

Her secret for sculpting her sleek, sexy back, core, arms, and shoulders: Pull-ups!

Not quite ready for that yet? Well, we got a substitute straight from the Calia designer’s trainer that will tone your upper-half and help you work up to a pull-up or chin-up.

Trainer: Erin Oprea

The move: Band-Assisted Chin-Ups

Why it’s so great: Can’t do a pull-up or chin-up on your own? These “work the same muscles—your lats and biceps—as the full-weight kind,” says Opera.

How to do it: Loop and secure a resistance band over a sturdy bar (like a pull-up bar or playground monkey bars) and place a foot in the loop. Hold bar with an underhand grip, hands shoulder-width apart (A). With abs engaged, bend elbows and pull body up until chin is above bar (B). Slowly lower back down. Do 4 sets of 5 reps 2 to 3 times a week.

Eating Nuts Could Save You From Early Death, Study Says

TIME-logo.jpg

Eating just a handful of nuts every day could help keep you from dying prematurely.

A new study published Thursday in the International Journal of Epidemiology found a 23% lower chance of death over 10 years in people eating at least 10 grams of nuts per day.

The researchers at Maastricht University in the Netherlands found the nuts were best at warding off death from respiratory disease, neurodegenerative disease and diabetes; the reduction rate was as high as 45% for respiratory disease.

But before you go grab a spoon: although peanuts showed similar effects as tree nuts, the researchers did not see a preventative benefit from peanut butter.

The study was performed through the Netherlands Cohort Study, in which more than 120,000 Dutch people ages 55 to 69 provided dietary and lifestyle information in 1986, and their mortality rate was examined a decade later.

How to Fix Text Neck and Improve Your Posture

DailyBurn-Life-Logo

There’s no denying that technology has transformed the way we live, from how we communicate and share information to how we navigate through life (thank you, Google Maps!). In other words, we’re glued to our devices. In fact, according to recent research, people spend approximately five hours every day on their smartphone, computer or tablet. And it might be taking a toll on your body.

Chances are you’re looking down at your device to read this article — head forward, shoulders rounded and back slumped, putting yourself at risk for the aches and pains now known as “text neck.” “You can stretch out and exhaust the paraspinal and upper back muscles from poor posture,” says Dr. Jonathan Stieber, orthopaedic spine surgeon and clinical assistant professor of orthopaedic surgery at the NYU School of Medicine. As the upper back rounds, the head and neck start to jut forward and out of alignment from your spine. No wonder your body hurts.

We know there’s no way you’re ditching your devices — so what can you do about the pain? Read on to find out.

How to Prevent Text Neck and Improve Your Posture

The Problem: Slouching
Your mother was right: Good posture matters. Pain related to technology use is often due to poor posture and ergonomics, according to Dr. Stieber. “When you’re sitting in front of your computer with a certain posture for hours on end, your body gets used to being in that position. It becomes your new normal,” says Ryan Balmes, DPT and board-certified clinical specialist in sports and orthopedic physical therapy in Atlanta. “Imagine if you’re arm wrestling all day. Your bicep muscles will be strained and they’re going to let you know that they are tired.”

While you usually don’t see severe problems like herniated disks or pinched nerves resulting solely from overuse of technology, Dr. Stieber says it can exacerbate an underlying condition. And be careful when you go for your weekend run or CrossFit WOD. “Your body may be shocked because you’re bringing it out of the position it’s accustomed to. You can be predisposed to injury,” says Balmes.

The fix: “Make sure you have the appropriate monitor, desk and chair height for you,” says Dr. Stieber. Can’t buy a new desk? “Keep your head is in a neutral position with your monitor at eye-level,” Balmes advises. “You want to have the height of the chair so that your feet can rest comfortably on the floor and your knees are at or just below [the level of] your hips.”

Sitting up straight might not come naturally at first. “[It] requires diligence, but more importantly, practice,” says Balmes. “As with all things, active practice will help solidify proper posture as habit.” One sign you’re not doing it right: “If anything in your body feels achy or uncomfortable after prolonged use, it’s your body’s way of screaming at you to change position and find a better one because it’s struggling to make your current posture work,” he says.

Frequent breaks from the screen can help, even if it’s just two minutes every hour. “Use the breaks as a reset.” says Balmes. “Set reminders on your phone or computer or use a Post-It note. These small cues can make a huge difference.”

The Problem: Text Neck
If you’re one of the 64 percent of American adults who owns a smartphone, look up now. Recent research from Dr. Kenneth Hansraj, chief of spine surgery at New York Spine Surgery and Rehabilitation Medicine, found that staring down at your phone can put incredible pressure on your neck and spine. Tilting your head forward 15 degrees places an additional 27 pounds of stress on the cervical spine. A 60-degree angle — the angle at which most of us view our phones — increases that stress to 60 pounds. That’s like carrying around a seven-year-old on your neck. Tablets also encourage you to flex your head forward. And, with bigger screens, you’re more likely to stay in that position for longer periods of time, according to Balmes.

RELATED: Why Your Fitness Tracker Isn’t Making You Thinner — Yet

The fix: The easiest way to address text neck is to change the way you hold your phone. “Bring the screen to eye level so your head is not slouched forward or too high,” says Balmes. “This way, you don’t have to be in a forward-head posture for a prolonged period of time.” When using a tablet, Balmes recommends buying a case that allows you to prop up the tablet on a table. To prevent stiffness in the neck, Balmes recommends neck rotations – look gently to the left and right, 10 times on each side. Try to perform these every hour throughout the day.

3 Posture Exercises to Balance Your Muscles

Strengthening and stretching your muscles may also help alleviate some of that nagging pain. While a visit to a physical therapist can help guide your specific needs, Balmes recommends these three quick exercises to help combat technology-induced slump.

RELATED: 7 Post-Workout Tools to Aid Muscle Recovery

Shoulder Blade Pinches

This move will help to strengthen the muscles of the upper back, which tend to get lengthened and weakened when you slouch.
How to: While sitting or standing straight, pinch your shoulder blades together and back. You’ll feel the front of your shoulders roll back. Hold for a few seconds, release and repeat. Perform 10 reps every hour throughout the day.

Pec Stretch

While slouching results in overstretched and feeble upper back muscles, it also leads to short and weak pecs, according to Balmes.
How to: Stand in a doorway and place your forearms against the frame of the door, with your elbows at shoulder height. With one foot forward, draw your shoulder blades together on your back and gently lean into the door. Hold the stretch for 30 seconds, then repeat once more. Perform this stretch three to four times a day.

Chin Tuck

A double chin may be a selfie no-no, but it can be good for your posture. Chin tucks strengthen the neck muscles and help you pull your head back into alignment.
How to: Sit up tall in a chair and keep your chin parallel to the floor. Without tilting your head in any direction, gently draw your head and chin back, like you’re making a double chin. Be careful not to jam your head back. You should feel a stretch along the back of the next. Release your chin forward. Repeat. You can perform 10 reps every hour throughout the day.

While the best advice is to take frequent breaks from your computer or cell phone, these exercises, along with improving your posture, are good preventative measures. “If this doesn’t relieve your pain, know that your problem may be more serious and seek out a physical therapist,” says Balmes.

Mouse Study Hints at Treatment for Itch-Related Ills Like Eczema

THURSDAY, June 11, 2015 (HealthDay News) — An itch that just won’t go away: Many people will suffer from eczema or some other ailment involving chronic itch during their lifetime, and a new study in mice hints at why this happens.

The scientists who’ve spotted a gene involved in chronic itch also believe the finding could lead to new treatments.

The study was co-authored by Rachel Brem, a geneticist and associate professor at the Buck Institute for Research on Aging in Novato, Calif.

“An estimated 10 to 20 percent of the population will suffer from chronic itch at some point in their lifetime,” Brem said in an institute news release.

“In addition to eczema, chronic itch can stem from systemic conditions including kidney failure, cirrhosis and some cancers,” she added. “Understanding the molecular basis of chronic itch is of significant clinical interest, and now there is a new target available to explore.”

Working with mice, the researchers pinpointed a nerve cell receptor called HTR7 as a major player in eczema and other types of chronic itch.

Mice created to have high levels of HTR7 in skin neurons had the worst itching, while those without the HTR7 gene scratched significantly less and had less severe skin problems.

While experts caution that studies in animals often fail to translate to humans, the researchers believe that HTR7 could be a new drug target for chronic itch.

Symptoms of eczema — which affects up to 10 percent of people worldwide — include intense itch, rash and dry, flaky skin. There is no cure for eczema, and current treatments to manage the condition are often ineffective.

Dr. Michele Green, a dermatologist at Lenox Hill Hospital in New York City, explains, “The problem with eczema is that the skin begins to itch and gets more irritated as the scratch-itch cycle is not alleviated.

“Currently, there are only topical emollients and antihistamines to help alleviate the symptoms of the rash, itching and burning of the skin,” she said.

But another expert said the new study offers patients new hope.

“This is a major breakthrough in our understanding of a common, yet, unsatisfactorily treated symptom associated with numerous dermatologic disorders,” said Dr. Andrew Alexis, chair of dermatology at Mount Sinai St. Luke’s and Mount Sinai Roosevelt in New York City.

He believes the new findings “set the stage for investigating a new therapeutic target for [chronic itch], which holds promise for the millions who suffer from eczema and other conditions.”

The study was published online June 11 in the journal Neuron.

Doctors Can Cut Back on Antibiotics After Abdominal Surgery: Study

THURSDAY, June 11, 2015 (HealthDay News) — The length of antibiotic treatment for abdominal infections can be cut in half and still be equally effective, a new study suggests.

Doing so could help efforts to battle the growing problem of antibiotic resistance, the study authors said.

The study — led by researchers at the University of Virginia — included more than 500 patients in the United States and Canada with abdominal infections. First, the source of the infection was treated, such as the removal of an inflamed appendix.

After surgery, half of the patients took antibiotics for eight days. The other half took antibiotics for only four days. Outcomes in both groups were similar, the study found.

“It’s important for physicians to realize the most important aspect of the management of these patients is controlling the source of infection,” Dr. Robert Sawyer, from the departments of surgery and anesthesiology, University of Virginia School of Medicine, said in a university news release.

“These data certainly suggest that if a good operation is performed, a short course of antibiotics may be all that is required,” he concluded.

The study findings were published online recently in the New England Journal of Medicine.

“There hasn’t been a lot of guidance on how long to treat intra-abdominal infections with antibiotics once you’ve gotten control over the source of infection,” Dr. Christopher Guidry, of the university’s department of surgery, said in the news release.

Guidry pointed out that overuse of antibiotics has an obvious downside.

“The increasing prevalence of antibiotic resistance is a problem, so anything we can do to minimize exposure is important,” he added.

Fidgeting May Help Children With ADHD to Focus

By Kathleen Doheny
HealthDay Reporter

THURSDAY, June 11, 2015 (HealthDay News) — Children with attention deficit hyperactivity disorder (ADHD) often fidget, but new research suggests intense fidgeting may actually help them focus on the task at hand.

If the research bears out, the traditional advice to encourage these children to sit still may be misguided, said lead researcher Julie Schweitzer, a professor of psychiatry and behavioral sciences at the MIND Institute of the University of California, Davis.

“Traditionally, it’s recommended that kids stay still and not be disruptive,” Schweitzer said.

But in her small study comparing 26 children with ADHD and 18 without the disorder, she found that when the children with ADHD were moving or fidgeting more intensely, they performed better on a test requiring attention.

Meanwhile, the movements of the children without ADHD did not affect test performance.

The study was published online June 11 in the journal Child Neuropsychology.

Why may fidgeting help the ADHD children?

“What I suspect is that kids with ADHD are moving to increase their attention by activating their arousal system,” Schweitzer speculated. “Being aroused does increase attention.”

The children all performed the same test, which required them to focus and to dismiss distractions. The children were asked to determine the direction of the middle arrow in a series of arrows. They needed to ignore the arrows surrounding the middle one.

The intensity of movement, but not its frequency, was linked with more correct answers in the children with ADHD. However, the research did not prove cause and effect, only a link or association.

The children in the study ranged in age from 10 to 17, and were 14 on average. Fifteen of the children with ADHD took stimulant medication, but stopped it for 24 hours before the testing.

Nearly 6 million children in the United States have a diagnosis of ADHD, according to the U.S. Centers for Disease Control and Prevention. Hyperactivity is a core symptom and one of the most observable hallmarks of the disorder, according to the researchers. The inability to sit still can cause challenges in school settings. Other symptoms include impulsivity and an inability to pay attention.

The theory of how fidgeting might help those with ADHD has been long talked about, said Brandon Korman, chief of neuropsychology at Nicklaus Children’s Hospital in Miami. However, he believes the new research is one of the first studies to test the theory.

One limitation of the finding, however, was the small number of children who were involved, he said.

Korman also does not think the findings suggest fidgeting is always acceptable for these kids.

“It doesn’t suggest we should let them fidget if it’s disturbing the other kids,” he said. He added that the researchers should look at the effect of physical activity before classwork, such as scheduling recess before academic tasks that require a lot of concentration.

Schweitzer said she would like to examine larger groups of children, to get a better idea of what is the best amount of movement for kids with ADHD.

“I’d love to tackle that in a future study, as it could guide parents and teachers,” she said, “although I suspect it would be different on an individual basis, with some children needing to move more than others for the movement to improve their task performance.”

Superior Visual Ability Found Early in Children With Autism

By Tara Haelle
HealthDay Reporter

THURSDAY, June 11, 2015 (HealthDay News) — Exceptional visual perception might be an early hallmark of autism, which could help predict a child will be diagnosed with the developmental disability, a new British study suggests.

Infants who more quickly perceived a mismatched symbol on a screen when they were 9 months old were more likely to receive an autism diagnosis by age 2, the researchers found.

“Although atypical perception, such as better visual search and hypersensitivity to sounds, are common in autism, they were rarely considered as a core feature in early development,” said study lead author Teodora Gliga of Birkbeck Babylab at the University of London. “Our finding is therefore striking since it strongly suggests atypical perception may be a driving force of later poor social interaction and communication symptoms.”

Most autism research to date has focused on difficulties children have with social interactions, behavior and communication, such as poor eye contact, the authors noted in their study. Focusing on above-average perceptual skills is a new direction to research.

These findings might also help clinicians eventually make diagnoses earlier since most children cannot receive a full clinical assessment until they are 2 or 3 years old, said study co-author Rachael Bedford, a postdoctoral researcher in psychiatry, psychology and neuroscience at King’s College London.

“It is difficult to know whether early impairments, such as communication difficulties, are specific to autism development, or might actually relate to a range of different developmental disorders,” Bedford said. “Our finding that infants’ superior perceptual abilities relate to autism might offer a more selective target for screening.”

This is the first time an enhanced early ability relates to early autism symptoms, she added.

The findings were published June 11 in the journal Cell Press.

It’s estimated that one in 68 U.S. children has an autism spectrum disorder. While there is no cure, early identification and services can improve a child’s development, according to the U.S. Centers for Disease Control and Prevention.

For the experiment, the researchers presented 109 infants with a screen showing a circle of Xs along with either an O, S, V or + sign as part of the circle. Then they used eye-tracking technology to time how quickly the odd letter out drew the infants’ attention at 9 months of age.

The infants also underwent standard assessments for autism symptoms at 9 months, 15 months and 2 years. Of the full group, 82 were at high risk for autism because an older sibling had been diagnosed with it. The other 27 children were at low risk.

By the time they turned 2 years old, 20 percent of the at-risk children had been diagnosed with autism, and another 30 percent showed several increased symptoms of autism, the researchers said.

When the researchers compared the children’s speed at noticing the letter that did not match the Xs, they found that children who saw it the fastest at 9 months old had more autism symptoms at 15 months and 2 years old.

“People with autism have both difficulties and strengths compared to the rest of us,” Gliga said. “We know some of the difficulties can be detected fairly early in life, but this study shows that unusual strengths can also be seen in infants.”

This doesn’t mean that every eagle-eyed infant will develop autism. While the study shows an association between a superior visual skill and later autism, it cannot show that children with exceptional visual perception will definitely develop autism, cautioned Dr. Glen Elliott, chief psychiatrist and medical director of Children’s Health Council in Palo Alto, Calif.

“It is far too early to tell whether this methodology will lead to earlier diagnosis of children at risk for development of autism,” said Elliott, who was not part of the research. “The sample size is too small and too narrow to permit generalizations about the utility of the technique, and much more information is needed for a diagnosis of autism spectrum disorder.”

That additional information reduces the chance that someone with autism is missed or that someone without autism is incorrectly diagnosed with it. At the same time, he added, this method is simple and noninvasive, making it valuable if the findings hold up in future studies and in the real world.

“This discovery potentially allows us to design future therapies around these infants’ strengths in order to enhance the later quality of life for individuals with the condition,” Gliga said.

The study was funded by Britain’s Medical Research Council.

Obese Postmenopausal Women May Face Higher Risk for Breast Cancer

By Steven Reinberg
HealthDay Reporter

THURSDAY, June 11, 2015 (HealthDay News) — A study of more than 67,000 women suggests that those who are obese and postmenopausal may face significantly higher odds for breast cancer compared with slimmer women.

The risk for breast cancer among the most obese women in the study was up to 58 percent higher than for normal-weight women.

In this study, the researchers said the most obese women had a body mass index (a measure of body fat) of 35 or higher. A woman who is 5-foot-7 and weighs 225 pounds would fall into that category.

“Obesity is a risk factor for breast cancer that is modifiable, making a healthy weight very important for prevention,” said lead researcher Marian Neuhouser, a professor of epidemiology at the Fred Hutchinson Cancer Research Center in Seattle.

In addition to increasing the risk for breast cancer, obesity was associated with worse outcomes, she said. Moreover, women who gained weight in early postmenopause increased their risk even if they were a normal weight at the start of the study, Neuhouser said.

While the study found an association between obesity and an increased risk of breast cancer, it did not prove a cause-and-effect link.

Neuhouser explained that the increased risk for breast cancer is probably due to an increase in estrogen.

“Obesity is known to increase estrogens in the postmenopausal women because estrogen is made by fat tissue,” Neuhouser said. “Fat tissue also secretes inflammatory factors and is associated with insulin resistance — all of which may increase breast cancer risk.”

Women who lost weight during the study reduced their risk for breast cancer, Neuhouser said. But the study was not about weight loss, therefore other studies are needed to really answer that question, she added.

“We can’t change our genes or family history, but we can change our lifestyle habits and aim to maintain a healthy weight to lower breast cancer risk,” Neuhouser said.

The report was published online June 11 in the journal JAMA Oncology.

For the study, Neuhouser and her colleagues collected data on more than 67,000 postmenopausal women who took part in a study called the Women’s Health Initiative from 1993 to 1998. During an average 13 years of follow-up, more than 3,300 women developed breast cancer.

The researchers found that very obese women were at risk for estrogen- and progesterone-driven breast cancer, but not for other types. These women were also more likely to have large tumors and cancer that spread beyond the breast and into the lymph nodes.

Women who gained more than 5 percent of their body weight over the years of the study also had an increased risk for breast cancer, according to the researchers.

Among women who were already overweight or obese, Neuhouser’s team found no change in risk for breast cancer whether they lost or gained weight over the 13 years of follow-up.

In addition, hormone replacement therapy had no effect on the risk for breast cancer, regardless of weight, the researchers said.

Dr. Clifford Hudis, chief of breast medicine service at Memorial Sloan Kettering Cancer Center in New York City and coauthor of an accompanying journal editorial, said, “Obesity is a growing concern in many ways, including its contribution to cancer, and we need to prioritize scientific and public policy decision-making to help limit the health burden it brings.”

He added that knowing the role obesity plays in the increased risk for cancer may help in understanding how and why some groups of people develop cancer, he said.

“From that, we may be able to develop better prevention and treatment in the future,” Hudis said.
