Concussion Tied to More School Problems Than Other Sports Injuries

FRIDAY, May 20, 2016 (HealthDay News) — Students who suffer a concussion may face more school difficulties than their peers with other sports-related injuries, a new study suggests.

Researchers found that concussed high school and college students had more trouble performing at a normal academic level one week later compared to students who injured their arms or legs.

“Concussed students typically return to school within a week after injury, while their brains are likely still recovering,” said Erin Wasserman and colleagues from the University of Rochester School of Medicine and Dentistry, in New York.

The study authors said their findings “emphasize the need for return-to-learn guidelines and academic adjustments based on gender and concussion history.”

For the study, the researchers analyzed visits to three emergency departments by high school and college students between September 2013 and January 2015. All of the students had a sports-related concussion or a musculoskeletal injury involving an arm or leg.

Using telephone surveys, the researchers compared self-reported academic problems after one week. The assessment was repeated one month after each student’s trip to the emergency room.

The study showed that concussed students faced more challenges. For instance, they were more likely to need tutoring and extra time to take tests.

The investigators also found that young women and students who had two or more previous concussions were more vulnerable to these negative effects.

However, the learning difficulties did not persist long-term, the study authors noted in a news release from the American Public Health Association.

According to the team led by Wasserman, who is now with the University of North Carolina at Chapel Hill’s Sport-Related Traumatic Brain Injury Research Center, one month after visiting the emergency room, students with a concussion no longer had worse academic performance than those with other injuries.

The results were published May 19 in the American Journal of Public Health.

Nutritional Label Overhaul Will Include Added Sugar Counts, Against Industry Complaints

The Nutrition Labeling and Education Act of 1990 required that all food manufacturers use a standard nutritional facts label. The law went into effect in 1994, and since then, those labels have stayed pretty much the same. The only significant change came in 2006, when trans fat was added under saturated fat. Today, Michelle Obama will announce an overhaul of that familiar nutritional label, and many of the changes reflect the way our understanding of health has evolved since 1990.

Here’s what you need to know about the changes to the label, which will take effect in two years.

Added sugar: This is the most significant change. The new labels will still list grams of total sugar, but they will also now break out the amount of added sugar, along with the percentage of the Recommended Dietary Allowance of added sugar. (The RDA for added sugar in a 2,000 calorie diet is 12 teaspoons.) That means, for instance, that 20 ounces of Coca-Cola would likely be labeled as containing 130% of your RDA of added sugar for the day. Total sugar includes the sugar that is naturally occurring in the food; added sugar is the amount of sweetener that was added.

RELATED: The Truth About Salt in Your Food

This change was fought vociferously by beverage and baked good industry groups who claim that there’s no meaningful difference between the sugar that’s naturally occurring in foods and the sugar that’s added. It’s true that there’s no chemical difference between the sugar that’s naturally occurring in grains, for instance, and the sugar that’s added, say, to Gatorade. But the FDA says that Americans currently get 16% of their total calories from added sugars, mostly from sources like soda, energy, sports and juice drinks, baked goods, and candy. The regulators argued that foods with lots of added sugars often have low nutritional value, and groups like the American Heart Association, the American Academy of Pediatrics, and the World Health Organization recommend that people cut their intake of added sugar. These new nutritional labels will make it easier for consumers to identify which products they should avoid.

Calories are easier to read; serving sizes are more realistic: Up top, you’ll notice right away that the number of calories per serving is in a larger, bolder font that’s easier to read. And the serving sizes have been adjusted from “ideal” size to a more realistic amount: One serving of ice cream will increase from 1/2 cup to 3/4 cup, for instance, and the calories and fat per serving will bump up correspondingly. Similarly, the serving size for sodas will increase from 8 ounces to 12 ounces.

RELATED: What Do ‘Healthy’ Food Labels Really Mean?

Removing calories from fat: Calories derived from fat will no longer be listed because current research suggests that the type of fat you consume is more important than the total amount of fat you consume. For instance, an avocado gets about 80% of its calories from fat. But that information isn’t very meaningful because the kind of fat that avocados contain is now understood to be healthful.

Vitamin D and potassium counts are mandated: Some vitamin and mineral counts are required to be listed on labels and some are optional. Vitamin D and potassium will no longer be optional because Americans tend to not get enough of them. Vitamins A and C are switching from required to optional because Americans do tend to get enough of them.

Growth Spurts Can Throw Off Teen Boys’ Strut

FRIDAY, May 20, 2016 (HealthDay News) — Growth spurts can affect teen boys’ coordination and knock the swagger right out of their stride, a new study reveals.

“A sudden increase in height affects the body’s ability to control established motor skills, such as walking,” said lead author Maria Cristina, of the University of Bologna, Italy.

The study included 88 boys who were 15 years old. Those with growth spurts — defined as a height increase of more than 3 centimeters (1.2 inches) over three months — had a more awkward gait than those with steady growth, the researchers found.

“Adolescents tend to show previous control of the body when growing up, but the motor control behavior is organized on the body’s dimensions. Following a growth spurt, the body needs time to adjust to changes to the periphery, during which time a teenager may walk awkwardly, while teenagers who grow steadily are able to handle growth modifications better and so maintain smoothness and regularity when walking,” Cristina explained in a news release from the journal Biomedical Engineering OnLine.

Growth spurts may not be the only factor that affects a teen’s coordination. Teens are experiencing a number of biological, mental, social and emotional changes that could also impact motor development, the researchers noted.

Cases of Pregnant U.S. Women With Zika Triple Under New Counting Method

By Steven Reinberg
HealthDay Reporter

FRIDAY, May 20, 2016 (HealthDay News) — The number of pregnant women in the United States infected with the Zika virus has just tripled because cases are now being counted in a more comprehensive way, federal health officials said Friday.

So far, a total of 279 infected women are being followed in the United States and its territories, according to two registries that have been created by the U.S. Centers for Disease Control and Prevention.

Previously, only cases of pregnant women who had Zika-related symptoms or pregnancy complications were being tallied, CDC officials said. But recently published reports have found that some pregnant women show no symptoms of Zika infection, yet still give birth to babies with a severe brain defect known as microcephaly.

“These updated numbers reflect all pregnant women in the United States and territories with any laboratory evidence of Zika virus infection, regardless of whether they had symptoms,” Dr. Margaret Honein, chief of the birth defects branch at the CDC’s National Center on Birth Defects and Developmental Disabilities, said during a Friday morning media briefing.

Using the new registries will provide a more complete picture of the effects of Zika on pregnant women in the United States, Honein added.

As of May 12, the two U.S. registries were monitoring 157 pregnant women in the United States and 122 pregnant women in U.S. territories who have laboratory evidence of possible Zika infection, CDC officials said. Before that, only 48 cases had been reported in the United States, while 65 cases had been reported in the U.S. territories, which include Puerto Rico.

Most of the women are still pregnant, and less than a dozen have had either a miscarriage or an infant with a birth defect, Honein said.

Zika is the first mosquito-borne illness known to cause birth defects, CDC officials have said. While the virus typically only prompts mild symptoms in most adults, it can cause fetal brain defects if a pregnant woman becomes infected.

Brazil has been at the epicenter of the Zika outbreak, with nearly 5,000 confirmed or suspected cases of microcephaly, which causes babies to be born with abnormally small heads and brains.

In the United States, the virus is expected to become active in at least some southern coastal states this summer, as it typically passes from person to person via the bite of the Aedes Aegypti mosquito, U.S. health officials have said. However, there have also been cases where Zika was transmitted through sexual contact.

To limit any potential spread of Zika virus via mosquitos, health officials on the federal, state and local level are deploying a three-pronged strategy: improving mosquito control; expanding their ability to test for Zika; and urging the public to protect themselves against mosquitoes.

On Friday, President Barack Obama said Congress has “got to get moving” on a Zika funding package to implement the U.S. government’s Zika prevention strategy, the Associated Press reported. Obama has asked Congress to allocate $1.9 billion to combat the Zika threat.

Researchers need time to develop a vaccine, and states need time to ramp up mosquito control programs, Obama warned.

The House and Senate have advanced bills to fight the virus, but the House version involves much less money, according to the AP. Obama is pushing for a funding package that comes closer to the $1.1 billion Senate bill.

Zika Cases In U.S. Pregnant Women Nears 300

There are 279 pregnant women in the United States and in U.S. territories who have Zika, health officials announced on Friday. There are 157 women pregnant women with the virus in the continental United States and 122 infected pregnant women in U.S. territories.

The new numbers are from the U.S. Centers for Disease Control and Prevention’s (CDC) Zika pregnancy registry systems in the U.S. and in Puerto Rico. The new numbers include all pregnant women who have had laboratory confirmation of a Zika infection regardless of whether they had symptoms or not.

Until now, the CDC defined and reported cases of Zika as people who had symptoms and a positive test for the virus. Since evidence suggests that pregnant women with Zika but without symptoms can also have babies with microcephaly, the agency will now report all pregnant women with evidence of Zika virus. Most people who get a Zika virus infection do not have symptoms.

FDA Unveils Makeover of Nutrition Facts Label

FRIDAY, May 20, 2016 (HealthDay News) — The Nutrition Facts panel on packaged foods in the United States is about to get a long-awaited facelift, with a redesign emphasizing realistic portion sizes and added sugars.

The announcement Friday by the U.S. Food and Drug Administration reflects changing science and an attempt to rein in Americans’ unhealthy eating patterns and help consumers make better choices, the agency said.

The updated design, for instance, will highlight “calories” and “servings,” and show how many grams of sugar have been added to a food, along with the percent daily value (%DV) for “added” sugars.

“It is difficult to meet nutrient needs while staying within calorie limits if you consume more than 10 percent of your total daily calories from added sugars, and this is consistent with the scientific evidence supporting the 2015-2020 Dietary Guidelines for Americans,” the FDA said in a news release.

Serving sizes will better reflect how much people really eat and drink. For instance, foods that can be downed in one or more sittings — such as a bag of chips or a pint of ice cream — will contain both “per serving” and “per package” calorie and nutrition information.

“People will be able to easily understand how many calories and nutrients they are getting if they eat or drink the entire package/unit at one time,” the FDA said. Quantities consumed have changed since the current serving size requirements were published in 1993, the agency noted.

When a container holds between one and two servings, such as a 20-ounce soda, the calories and nutrient information now must be labeled as one serving because that’s how people usually drink it.

“For more than 20 years, Americans have relied on the Nutrition Facts Label as a leading source of information regarding calories, fat and other nutrients to help them understand more about the foods they eat in a day,” FDA Commissioner Dr. Robert Califf said. “The updated label makes improvements to this valuable resource so consumers can make more informed food choices — one of the most important steps a person can take to reduce the risk of heart disease and obesity.”

First Lady Michelle Obama, who has made obesity prevention a priority, was expected to discuss the redesign on Friday.

“I am thrilled that the FDA has finalized a new and improved Nutrition Facts label that will be on food products nationwide,” she said in the news release. “This is going to make a real difference in providing families across the country the information they need to make healthy choices.”

The final revision comes more than two years after the new rules were proposed.

Here’s what else you’ll see when the law takes effect in July 2018:

  • Updated daily values for salt, dietary fiber and vitamin D, in keeping with the 2015-2020 Dietary Guidelines for Americans and recommendations from the Institute of Medicine. “Daily values are reference amounts of nutrients to consume or not to exceed and are used to calculate the %DV that manufacturers include on the label,” the FDA noted.
  • Vitamin D and potassium content will include both total grams and the %DV. Some people are deficient in these nutrients, putting them at higher risk for chronic disease, the FDA said.

You’re unlikely to see values for vitamins A and C. They’re no longer required because deficiencies of these vitamins are rare, although food makers can choose to include them, the FDA said.

The agency is also saying goodbye to “Calories From Fat” because research shows the type of fat is more important than the amount. “Total Fat,” “Saturated Fat,” and “Trans Fat” will still be required.

The new label must be used by July 26, 2018, by most manufacturers. However, food makers with less than $10 million a year in sales will have until 2019 to comply.

Nutritionists applauded the FDA’s move.

“This is a major breakthrough in nutrition history. As obesity rates rise it is important for consumers to be able to interpret fool-proof nutrition facts,” said Sharon Zarabi, a nutritionist at Lenox Hill Hospital in New York City.

“It’s no wonder half the patients I see are confused with the current food labels. It’s nearly impossible to give someone a bottle of a sweetened beverage, listing calories and sugar for ‘half’ the bottle and expect us not to drink it all.”

Connie Diekman is director of nutrition at Washington University in St. Louis. “As a registered dietitian I am happy to see the addition of ‘added sugars’ to the label,” she said. “This addition will not only make the amount of added sugars clear, it will also help consumers see the presence of natural sugars, sugars that come with the total nutrient package of a food.”

She also said the inclusion of “real” servings sizes will hopefully help people decide how much to consume.

Diekman also said the “inclusion of potassium and vitamin D are important minerals for overall health and might help consumers make food choices based on nutritional value, not just fat, calories or carbs.”

Added registered dietitian Christine Santori, program manager at the Center For Weight Management at Northwell Health’s Syosset Hospital in New York: “Finally, a food label consumers have a chance of understanding! Teaching clients to understand and navigate the food label has always been a challenge. The improvements made with this model have been a long time coming.

“Now, serving sizes must reflect what consumers realistically will have. Not too many people will have only half of a 20-ounce soda bottle, but those are the serving sizes upon which the calorie information has been based,” she added.

Frat Brothers Keep Chugging Despite Anti-Booze Efforts

FRIDAY, May 20, 2016 (HealthDay News) — The boys of “Animal House” and “Neighbors” may be immune to anti-boozing programs that curb drinking for other college kids, new research suggests.

As Brown University researcher Lori Scott-Sheldon put it: “Current intervention methods appear to have limited effectiveness in reducing alcohol consumption and alcohol-related problems among fraternity and possibly sorority members.”

Scott-Sheldon’s team reviewed data on more than 6,000 fraternity and sorority members. The information came from 15 studies done over 25 years. Overall, the researchers looked at 21 different interventions aimed at reducing on-campus drinking.

The investigators found no differences in drinking behaviors between those who had received some kind of anti-drinking intervention, and those who had not.

That was true across all measures — how much the students drank per week or month, frequency of heavy drinking, number of days they drank, or alcohol-related problems, the study showed.

In some cases, students drank even more after an intervention, Scott-Sheldon’s team said.

Are sorority sisters as impervious to anti-alcohol efforts as their frat peers? The study authors say that’s not clear. They noted that since only 18 percent of the study participants were women, and none of the studies focused solely on sororities, the findings may only apply to members of fraternities.

What is clear is that “reducing alcohol consumption and problems among fraternity and sorority members will require a different strategy relative to their college drinking peers,” Scott-Sheldon said.

The researchers were surprised that conventional interventions had zero effect on the typical drinking frat member.

“We expected that providing Greek members with a thoughtfully designed and carefully administered alcohol intervention would reduce consumption and problems relative to no intervention,” Scott-Sheldon said in a news release from the American Psychological Association.

The bottom line, she said, is that “stronger interventions may need to be developed for student members of Greek letter organizations.”

The study was published online May 16 in the journal Health Psychology.

Delayed Treatment for Concussion May Prolong Recovery

By Don Rauf
HealthDay Reporter

FRIDAY, May 20, 2016 (HealthDay News) — Athletes should not take a blow to the head lightly. New research suggests delayed treatment for concussion could prolong recovery.

Many college athletes, however, don’t immediately recognize or report concussion symptoms, the study of nearly 100 players found. And compared to head-injured athletes who were evaluated right away, those who put off reporting symptoms were sidelined about five days longer on average.

“If you are an athlete and you are experiencing concussion symptoms, you should immediately engage your athletic trainer or team physician so that you can be evaluated,” said the study’s lead author, Breton Asken.

“Our findings indicate that … will give you the best chance to return to your sport more quickly,” said Asken, a graduate student in the clinical psychology program at the University of Florida.

Putting off medical attention potentially exposes an athlete’s already injured brain to additional stress that can compound damage to the nervous system, Asken added.

According to the U.S. Centers for Disease Control and Prevention, concussion signs may include headache or “pressure” in the head; nausea, or vomiting; balance problems or dizziness; double or blurry vision; annoyance from light or noise; confusion; and concentration or memory problems.

Coaches should remove athletes from play. And the athletes should seek medical attention if they can’t recall events prior to the hit or fall; appear dazed or confused; forget instructions; answer questions slowly; or lose consciousness even briefly. Individuals with a concussion may say they just don’t “feel right,” or feel sluggish or foggy, the CDC says.

Although awareness of long-term concussion damage has increased over the past decade, many sports-related head injuries still go unreported, the new study confirmed.

For this study, Asken and his colleagues reviewed medical records of 97 male and female University of Florida athletes diagnosed with a sport-related concussion between 2008 and 2015. The athletes had participated in basketball, football, gymnastics, lacrosse, soccer, swimming and diving, track and field, or volleyball.

More than half did not immediately report their concussion symptoms, the study found.

After taking into account other factors that could prolong recovery, the investigators found that athletes who delayed reporting a concussion still took an average of 4.9 more days to resume playing compared to those who immediately reported concussion symptoms.

Athletes who delayed reporting were also more than twice as likely to have a prolonged recovery — eight or more days — compared to those who stopped playing their sport immediately, the findings showed.

Asken said there are likely several reasons for the delays in reporting symptoms. For instance, some athletes may not associate symptoms such as headache or nausea with a concussion.

“It is also conceivable that some either did not notice symptoms while playing or they did not deem them serious enough to report,” he said. “They only reported symptoms after they persisted and signaled that something must be wrong.”

The findings were published in the May issue of the Journal of Athletic Training.

Tamara Valovich McLeod is a co-author of the National Athletic Trainers’ Association position statement on management of sport concussion. She said some athletes may worry about losing their position or letting their teammates down if they report a concussion.

Prior research has shown that many adolescent athletes minimize and mask symptoms “in order to feel normal among their peers and to get back to playing as quickly as they can,” said McLeod.

She is also director of athletic training programs at the School of Osteopathic Medicine at A.T. Still University in Mesa, Ariz.

“I think athletes often do want to play through an injury, including concussion, as there is a lot of their identity tied into being an athlete and on the field,” she added. “Changing this perspective is important to ensure athletes do report symptoms associated with concussion so they are managed appropriately.”

Both McLeod and Asken agreed that education can help boost the number of athletes who report concussions immediately.

“Not only should we educate on what the signs and symptoms of concussion are, but let athletes know the importance of immediate reporting and how immediately reporting may allow them to return to activity safer and faster than hiding symptoms,” said McLeod.

Elderly Benefit From Intensive Blood Pressure Treatment

FRIDAY, May 20, 2016 (HealthDay News) — Intensive treatment of high blood pressure reduces older adults’ risk of heart disease without increasing their risk of falls or other complications, a new study shows.

“These findings have substantial implications for the future of high blood pressure therapy in older adults because of its high prevalence in this age group, and because of the devastating consequences high blood pressure complications can have on the independent function of older people,” said study author Dr. Jeff Williamson. He is a professor of gerontology and geriatric medicine at Wake Forest Baptist Medical Center, in Winston-Salem, N.C.

These new results come from the U.S. National Institutes of Health’s Systolic Blood Pressure Intervention Trial (SPRINT).

The study included more than 2,600 patients, aged 75 and older. They were randomly assigned to one of two groups: either an intensive systolic blood pressure target of 120 mm Hg or the standard target of 140 mm Hg.

Systolic pressure, the top number in a blood pressure reading, measures the pressure in your blood vessels when your heart contracts.

On average, patients in the intensive target group required one additional medication to achieve their goal.

Compared to those in the standard target group, patients in the intensive target group were nearly one-third less likely to have a heart attack, heart failure or stroke, and nearly one-quarter less likely to die, the study authors said.

There was no difference in rates of complications from lower blood pressure, such as fainting, falls, hospitalization and acute kidney injury, according to the study.

High blood pressure affects 75 percent of Americans older than 75. Current guidelines about systolic blood pressure treatment in elderly patients are inconsistent, the researchers noted.

“Some of the most vulnerable ambulatory people in the community who may suffer complications of high blood pressure can benefit from intensive blood pressure lowering and it is safe to do so,” Williamson said in a Wake Forest news release.

“If you look at elderly people who are hospitalized in the year that they become disabled and have to leave their home, about half the time those diagnoses or hospitalizations result from complications of [high blood pressure], like heart failure, stroke and heart attack,” he said.

Most of the medications used in the study were generic, Williamson said. “This is a fairly inexpensive way to help prolong the time that people can live independently in their homes and avoid those common conditions that often cause a person to have to move to higher level of care or an institution,” he said.

The study results were published May 19 in the Journal of the American Medical Association.

Folic Acid for Moms-to-Be Not as Effective as Thought?

By Alan Mozes
HealthDay Reporter

FRIDAY, May 20, 2016 (HealthDay News) — Fortifying cereals, grains and flour with folic acid has not protected against the risk of certain birth defects as much as experts thought it would, a large, new study suggests.

At issue are neural tube defects, which include anencephaly, a fatal condition where a baby’s brain does not develop, and a paralyzing spinal cord deformity known as spina bifida.

In the late 1990s, health experts found that low folic acid blood levels were linked to both birth defects. So, the U.S. Food and Drug Administration mandated that cereal and grain products be fortified with the B vitamin.

To measure just how effective that effort has been, investigators from Stanford University School of Medicine analyzed 1.3 million births across eight central California counties over two decades.

Between 1989 and 2010, there was an average of about 88 cases of neural tube defects for every 100,000 births.

But digging deeper, investigators found that that risk had already started to decline before the 1997 fortification mandate. There was a risk drop of nearly 9 cases per 100,000 births every year between 1989 and 1996 alone, the researchers said.

And that downward trend actually slowed after fortification, dipping by 1.7 cases for every 100,000 births annually between 1999 and 2010, the study authors said.

Study co-author Gary Shaw, associate chair of clinical research at Stanford’s department of pediatrics, said a number of unexamined factors might have played a role in the trend, including a notable rise in maternal obesity.

“And we now have to wonder if folic acid is the whole answer,” he said.

“What we do know, however, is that this is not a message to women that they should now do anything differently,” Shaw stressed. “I certainly do not want to convey that folic acid doesn’t work. We’re all very grateful that we found folic acid a while back. And it works.”

That thought was seconded by Laura Baldwin, a public health analyst with the U.S. National Center on Birth Defects and Developmental Disabilities, part of the Centers for Disease Control and Prevention.

“CDC researchers have found that since folic acid fortification began in the United States, about 1,300 babies are born each year without a neural tube defect who might otherwise have been affected,” she said.

“Folic acid has been shown to be effective in preventing neural tube defects in randomized control trials, community intervention programs and food fortification programs,” Baldwin added.

The bottom line?

“The benefits of folic acid for the prevention of neural tube defects are well-documented,” said Baldwin. “The CDC continues to recommend that, to reduce their risk for a neural tube defect-affected pregnancy, women capable of becoming pregnant should take 400 micrograms of synthetic folic acid daily, from fortified foods or supplements or a combination of the two, in addition to consuming food with folate from a varied diet.”

Shaw and his colleagues reported their findings online May 18 in the journal Birth Defects Research Part A.
