More Progress Needed To Get Stroke Patients Rapid Care

FRIDAY, July 31, 2015 (HealthDay News) — Stroke victims still aren’t getting treated soon enough, a new study suggests.

Treating strokes quickly is critical, because the more time that elapses, the less effective stroke treatment may be, the researchers explained.

A number of factors have reduced the time it takes stroke patients to get treatment. These include greater public awareness, better emergency dispatch procedures and improvements in hospital stroke units, the researchers said. But, delays in transporting stroke patients from regional hospitals to comprehensive stroke centers are still common, the team found.

“Stroke requires a multi-disciplinary team that engages in a nuanced chain of events leading to treatment, and efficient and prompt patient transport via emergency medical services [EMS] is a significant link in the process,” study author Dr. Michael Froehler, neurointerventionalist at the Cerebrovascular Program at Vanderbilt University Medical Center, said in a Society of NeuroInterventional Surgery news release.

“Within the broader stroke community, we’ve definitely made progress in our systems of care that ensure an increasing number of patients receive treatment as quickly as possible. But we need to do more,” he added.

In conducting the study, researchers recorded the amount of time it took to transfer 70 patients from hospitals that were not equipped to handle all levels of stroke to major stroke centers. Over the course of one year, they found transfer times ranged between 46 and 133 minutes. Those times were longer than it would have taken to drive the distance between the facilities, the researchers noted.

Stroke is the number one cause of disability and the fourth leading cause of death in the United States, the researchers said. Stroke cost about $54 billion in health care expenses and lost productivity in 2010 alone. Disability-related health care expenses resulting from strokes also cost $74 billion each year, they noted.

The findings were presented this week at the annual meeting of the Society of NeuroInterventional Surgery in San Francisco. Findings from meetings are generally viewed as preliminary until they’ve been published in a peer-reviewed journal.

Mountain Biker Survives After Neck Impaled by Tree Branch

By Alan Mozes
HealthDay Reporter

FRIDAY, July 31, 2015 (HealthDay News) — A day out mountain biking went terribly wrong for one middle-aged man in New Mexico: He ended up with a tree branch impaled in his neck.

Fortunately for the unnamed man, he had the good sense to leave the branch where it was and quickly seek help, according to a new case study published recently in the New England Journal of Medicine.

The 40-year-old, who was in good health, initially set off on his mountain bike to ride an off-road trail in New Mexico.

At some point during the ride, he fell from the bike onto a tree branch, which got lodged in his neck. The tree branch — roughly three-quarters of an inch in diameter — lodged more than half an inch deep into the left side of his neck, his doctors said.

Attending physician Dr. Lev Deriy, an assistant professor in the department of anesthesiology and critical care at the University of New Mexico (UNM) in Albuquerque, believes the “patient was definitely lucky considering the location of injury.”

“The neck has quite a few vital organs, like the trachea, carotid artery, jugular vein and nerves just a few millimeters from the skin surface.” Damage to any “could cause a quick death from massive bleeding and/or airway compromise,” Deriy said.

“On the other hand, the patient’s actions played a significant role in the positive outcome in this case,” he noted. “After he fell and the wooden branch stuck deep in his neck, he decided not to take it out, rode his bike to his car, and drove to the nearest hospital, which was 20 miles away.”

Doctors in the ER also left the branch in place. It was removed during surgery, and the man had a full recovery.

Bikers should be aware that mountain bikes and bikes designed for use on paved roads have differing safety concerns. For example, according to a study led by Dr. Derek Roberts of the University of Calgary — and published in the Canadian Journal of Surgery — most street cycling accidents result from being struck by a car.

By contrast, off-road mountain bike accidents involve some sort of loss of control causing a fall off a cliff, a pathway or an embankment, the Canadian authors wrote.

In the case of Deriy and Gerstein’s patient, ER physicians noted that the impaling branch had not caused any vascular damage or injury to the man’s airway passages, and that the patient’s decision to leave the branch in place probably prevented significant blood loss.

“In fact,” noted Deriy, “it was left in place by emergency room doctors and removed only by the surgeon in operating room after general anesthesia was induced and the patient’s airways were secured.”

“I think the patient’s ability to clearly analyze this potentially very dangerous situation and take the best course of actions in order to help himself makes this case especially unique,” he said.

Dr. Rodney Baker, clinical director of the division of emergency medicine at Nicklaus Children’s Hospital in Miami, agreed, “This type of injury is actually pretty uncommon.”

“In my years in practice I’ve only seen one similar type of incident,” he noted. “So it’s really hard to predict with 100 percent certainty what the best course of action would be in a case as unusual as this.

“But yes, it is true that the trauma literature would support that a patient impaled in this kind of situation should not, if possible, try to remove the impaling object. Not doing so was probably helpful in arriving at a good outcome,” Baker said.

What Drives Trophy Hunters Like Walter Palmer?

scienceofuslogos.jpg

When this week began, chances are high that you’d never heard of Cecil the lion, the beloved big cat of Zimbabwe’s Hwange National Park. But by now, you’ve likely heard of his death. Walter Palmer, a Minnesota dentist, paid about $55,000 for the (illegal) privilege of lion-hunting — though, after two days of tracking Cecil, it in the end wasn’t much of a hunt: Palmer and his guides reportedly used bait to lure the 13-year-old lion a half-mile outside of the protected park area. There, Palmer shot the animal with a bow and arrow, inflicting a severe wound that would lead to the animal’s death. The New York Times reports that Palmer had planned to mount Cecil’s head upon returning home.

Palmer has since expressed his regret over killing Cecil, claiming in a statement to the Star-Tribune on Tuesday that he did not realize that what he had done was not legal, or that Cecil was a famous and well-loved lion, or that the animal was the subject of an ongoing research project with Oxford University. But his words suggest that if Cecil hadn’t been famous, Palmer would regret nothing. He is, after all, a member of Safari Club International, a nonprofit “hunters’ rights” organization; the Safari Club website has a list of Palmer’s 43 kills, which include, among other things, a polar bear.

The question, then, is why? What motivates Palmer and other trophy hunters, as they’re called, to fly thousands of miles and spend tens of thousands of dollars, all for the sake of killing an animal like Cecil? The answer is complex, but, largely, it can be thought of as a demonstration of power and prestige, says Amy Fitzgerald, a sociologist at the University of Windsor.

In 2003, Fitzgerald and Linda Kalof of Michigan State published research in the sociology journal Visual Studies in which they analyzed 792 “hero shots” — the post-kill photo of hunter and prey — published in 14 popular hunting magazines. Most of the shots, Fitzgerald recalls, seemed to be arranged to show the hunter’s dominance over the animal. “The hunter tended to be pictured above standing or sitting above the animals, which clearly demonstrated the power dynamic that was going on there,” Fitzgerald said. In the vast majority of photos she and Kalof examined, the animal had been cleaned up, blood scrubbed away and wounds carefully hidden from view, making the animal look almost alive — as if the hunter had somehow tamed this giant, wild creature into submission. “It seems like, with the large animals, they were positioning them as though they were alive as a way to confirm the contest that had gone on — that this was a large virile animal that had to be taken down,” Fitzgerald said.

A show of power via dominance over the animal kingdom is, of course, nothing new. “This is something that goes back to antiquity, when kings had fake hunts with captured lions released just to be shot from a chariot by the waiting king,” Kalof said in an email to Science of Us. These “hunts” were done in front of an audience, which was a way of publicly declaring and validating the king’s power, Kalof noted, adding that “the trophy hunt of today is similarly a display of power and control by wealthy men.” Indeed, what Kalof describes sounds similar to today’s so-called “canned hunting,” which takes place in an enclosed area in order to increase the likelihood that some rich — and, often, American — tourist will nab a kill. (Noted fans of the canned hunt include Donald Trump’s two sons, Eric Trump and Donald Trump Jr.)

Michael Gurven, an anthropologist at the University of California at Santa Barbara, studies hunter-gatherer tribes in the Amazon and notes that, both in cultures where hunting is necessary for survival and in those where it is not, the skill certainly attracts attention, though for wildly different reasons. “There’s the element of conspicuous consumption,” Gurven said. “I study people who hunt for food because they have no other choice. And here is someone paying $50,000 — which, as an annual income, that would be well above the poverty line — to have the opportunity to put himself in potential danger in order to kill a lion.”

Another huge part of the draw for trophy hunters, of course, is the thrill, or the element of danger. But in Palmer’s specific case, this, too, ties back to the wealth element, Gurven argued. “When you’re paying $55,000 for something, it’s probably a sign that — if it’s not necessarily illegal, certainly the animal you’re hunting is rare,” Gurven said. “If you think about the danger of the actual hunt — sure, the animal itself is dangerous.” But with Cecil, at least, the lion’s familiarity with humans likely made him an easy target, Louis Muller, chairman of Zimbabwe Professional Hunters and Guides Association, told the Telegraph. “But the potential illegality of it — I think that makes it dangerous for a different reason,” Gurven said. “How do you smuggle the head or whatever he was going to take back to the U.S.? Getting that animal head on the wall is another signal of strength.” (Of course, there are plenty of trophy hunters who pursue the sport they love legally — he’s not talking about them here, just this one specific case of the lion and the dentist.)

The argument trophy hunters themselves often give is that killing the animals is an unlikely act of charity, and that the massive amounts of money tourists fork over helps to fund conservation efforts. Cecil’s death has reignited debate over that argument, but some major mainstream organizations have previously backed it, including the World Wildlife Fund. In a 2009 profile of Palmer in the New York Times, the curator of a bow-hunting club called Pope and Young explains that, yes, part of the draw is the “personal achievement” factor. But there’s another part to it, Glen Hisey explained. “It is a way of honoring that animal for all time,” he told the Times. Put differently, it’s a way of immersing yourself in nature in a way that modern life doesn’t always allow. As the conservationist and writer Aldo Leopold once noted (as quoted in the magazine Montana Outdoors), “Poets sing and hunters scale the mountains primarily for one and the same reason — the thrill to beauty. Critics write and hunters outwit their game for one and the same reason — to reduce that beauty to possession.”

 mimi-logo-il6.jpg

It’s always fun to mock the ridiculous beauty trends we loved in the ’90s (feathered bangs, anyone?), but the Last Great Decade deserves some more respect. Despite all the tacky neon packaging and a seriously unhealthy fascination with glitter, the ’90s was actually a rather simple time. It was about using scientific advancements to find solutions to everyday problems, like frizzy hair or oily skin. Like Vanilla Ice once famously said, “If there was a problem, yo, I’ll solve it.”

Not surprisingly, many of the beauty products that were popular in the ’90s have endured as timeless staples that still hold up today. When I started this article I was planning to feature only five products, but there were just too many good ones to choose from. As they say, if it ain’t broke don’t fix it, right?

Aveeno Soothing Bath Treatment

Whenever my skin is feeling a little dry and irritated, I draw myself a warm bath and sprinkle in this dermatologist-recommended colloidal oatmeal mix — just like I did as a child. Except sans rubber ducky this time.

$6.19; Amazon

Biore Deep Cleansing Pore Strips

There’s a reason everyone fell in love with CK One back in the day: because it smells like what being a teenager feels like. So break out your Cranberries CD and spray yourself silly until it feels like 1994 all over again…

$49; Sephora

Clinique Facial Soap with Dish

It was the summer of 1995 and I was 11 years old. My roommate at ballet camp (yes, that’s a thing) had a face soap she swore by and was nice enough to let me try it out. This was my first introduction to Clinique and I’ve been a loyal customer ever since.

$14; Sephora

Jergens Daily Moisturizer

There’s not much you can rely on in this world — except for Jergens body lotion. It was a staple in my house growing up in the ’90s, and to this day it remains one of my go-to fixes for dry skin.

$5.64; Amazon

Caboodles

Truth: the Caboodle is one of the most practical inventions of our time. I remember toting my sticker-clad Caboodle everywhere, just in case I needed a quick touchup or an emergency bobby pin. I wouldn’t recommend opting for the same sparkly one you owned as a tween, but if you wanted to go old school, I certainly wouldn’t judge.

I can clearly recall being a little kid and standing in the shower counting to 180, beyond excited to rinse and feel my silky, smooth hair between my fingers. Nothing tamed my South Florida frizz quite like Aussie’s classic conditioner. And the best part? It still gets the job done. All together now: 1… 2… 3…

$2.97; Amazon

Clean & Clear Oil-Absorbing Sheets

When this product first hit the market I remember thinking it was the best invention EVER. I mean, pocket-sized pieces of paper that soak up your oil? Brilliant. Just because you’re not in high school anymore doesn’t mean you’ve stopped suffering from the occasional (read: frequent) bout of forehead perspiration. As the commercial says, these little sheets will keep you “clean, clear, and under control.”

This cult classic serum changed my life in 6th grade. I started using it after a boy in school asked why my hair looked so crazy (somehow we’re still friends). I made a mad dash to the bathroom and realized that by “crazy” he actually meant frizzy. So I went home that day, coated my hair with a few pumps of the good stuff, and returned to school a new woman.

The Science of Why You Crave Comfort Food

Photo: Getty Images

TIME-logo.jpg

In mid-July, I was visiting my hometown in Minnesota when I happened upon the unmistakable scent of something deep-fried. I was at a concert, and no matter how off-brand a dietary choice of corn dogs and cheese curds may be for a health writer, I went for it. How could I not? I spent two thoroughly enjoyable summers during college working at the Minnesota State Fair, and that experience continues to make corn-and-grease-dipped hot dogs not only appetizing but somehow irresistible, too.

Summer is the season for nostalgic eating: Hot days in the park call for a trip to the ice cream truck, concerts call for corn dogs, baseball games call for hotdogs and beer, ice-cold movie theaters call for popcorn. And it’s not just me. Researchers suggest that when we associate foods with happy memories, the effects are profound, impacting how good we think foods taste as well as how good those foods make us feel.

It makes intuitive sense that positive experiences with a given food could influence our craving for it later on, but recent research also suggests something else is at play, too: comfort foods remind us of our social ties, which means they may help us feel less lonesome when we feel isolated. In a recent July 2015 study, Jordan Troisi, an assistant professor of psychology at Sewanee, The University of The South, and his colleagues found that people with strong relationships preferred the taste of comfort food when they experienced feelings of social isolation.

“Comfort food seems to be something people associate very significantly with close relationships,” says Troisi. “This probably comes about by individuals coming to associate a particular food item with members of their family, social gatherings, and people taking care of them, which is why we see a lot of comfort foods [that are] traditional meals or things had at a party.”

Of course, what counts as comfort food is different person to person. When Troisi has asked people write about an experience they’ve had with a comfort food, essays have ranged from soup to kimchi. “It’s not just that ice cream, for instance, is really tasty. It’s that someone has developed a really significant meaning behind the idea of ice cream due to their relationships with others, and that’s what is triggering this effect,” he says.

Even the smell of a meaningful dish can elicit feelings of belonging, some research suggests. In a February 2015 study, Virginia Commonwealth University researcher Chelsea Reid and her colleagues had 160 people smell 12 different scents, including apple pie, cotton candy and baby powder and rate the extent to which the scent was familiar, arousing, autobiographically relevant, and the extent to which it elicited nostalgia. “Nostalgia can be evoked in different ways, but scents may be particularly likely to evoke nostalgia due to the strong link between scents and memory. The smell of pumpkin pie might bring all those holidays with family flooding back, or the smell of a familiar perfume might arouse memories with your partner,” says Reid.

Biologically speaking, scent and memory are closely tied. “Psychological research has demonstrated that smells are powerfully linked to memory, and to autobiographical memory in particular,” says Reid. “The olfactory bulb, which is involved in the sense of smell, is linked to areas in the brain associated with memory and emotional experiences.”

Humans have a fundamental need to belong, says Reid, and because nostalgia often centers around personal events involving people they care about, she sees the evocation of nostalgia as one way people can obtain a sense of belonging even when the people they are close to are not close by.

So while corn dogs in the summer may not be fine dining by any standard, for me, they trigger happy memories of summers long ago—and that’s a good thing. In moderation, of course.

What Is Legionnaires’ Disease? All About the Germ Causing the New York City Outbreak

An outbreak of Legionnaires’ disease in the South Bronx has killed two people and sickened dozens more, and New York City health officials are urging anyone with symptoms of the lung infection to promptly seek medical attention.

But wait, wait, wait. What is Legionnaires’ in the first place?

From 8,000 to 18,000 people are hospitalized each year in the US with Legionnaires’ disease, according to the Centers for Disease Control and Prevention. It’s an infectious disease, but unlike other things like influenza and the common cold, it doesn’t spread from person to person; people catch it by inhaling mist from water systems harboring Legionella bacteria. The first known outbreak occurred in 1976, at an American Legion convention in Philadelphia, which is where the name comes from.

RELATED: 5 Ways to Tell If You Need an Antibiotic

Symptoms can show up two days to two weeks after someone is exposed, and can include fever, cough, chills, muscle aches, headache, fatigue, confusion, loss of appetite, and diarrhea.

“It is a true bacterial pneumonia. That’s why it is severe, but at the same time it doesn’t make everyone ill, and it doesn’t kill everybody,” Hassan Bencheqroun, MD, an interventional pulmonologist and critical care specialist at Pacific Pulmonary Medical Group, and an assistant clinical professor at the University of California, Riverside, explained to Health. “Those that develop the pneumonia and those that die from it are those that have risk factors.”

These risk factors include:

  • Being 50 or older
  • Having a chronic lung condition such as asthma or emphysema
  • Smoking cigarettes
  • Taking medications that suppress the immune system
  • Having an immune-suppressing illness

RELATED: 10 Places With Measles or Other Outbreaks

Legionella pneumophila is the strain responsible for 90% of cases of Legionnaires’ disease. The bug lives in the condensers of large air conditioning systems, hot water tanks, whirlpool spas, cooling towers, even ornamental fountains. While low levels of the bacteria won’t lead to an outbreak, “it’s when it multiplies to the level that it would cause disease that we worry,” Dr. Bencheqroun explained.

Legionella is usually a rarer cause of pneumonia,” Belinda Ostrowsky, MD, MPH, infectious disease attending physician and director of antibiotic stewardship at Montefiore Health System in the Bronx, added in an interview with Health. “In the Bronx we can see clusters (increased number of cases) in the summer months.  Clusters can also be seen at times due to specific environmental sources.”

Investigators have honed in on cooling towers at the region’s busiest hospital and a mall/movie theater complex as the source of the current outbreak underway in the Bronx. To confirm that these structures are the outbreak source, medical sleuths must match the DNA signature of the bacteria in the towers to the bacteria that’s making people sick.

RELATED: 14 Types of Food That Can Make You Sick

Death rates from Legionnaires’ disease range from 5% to 30%. Some patients will get better with just a few days of intravenous antibiotics, while others may need to spend ten days to two weeks in the intensive care unit, according to Dr. Bencheqroun. “Most of these people have an incredible amount of inflammation in the lining of their lungs, so their oxygen level is very low,” he says. Some people may simply need some extra oxygen, while others may need to be on a ventilator.

The good news, Dr. Bencheqroun says, is that inexpensive, very effective drugs for treating Legionnaires’ disease are available. “We have excellent antibiotics that treat this pneumonia, and these antibiotics are not complex, third tier, only-accessible-to-the-rich kinds of antibiotics,” he said. “Most of the cases of Legionella pneumonia that we diagnose, we send home, and they restart their life with just a story to be told.”

Mineral Supplement: Wild Chimps May Eat Clay for Health

FRIDAY, July 31, 2015 (HealthDay News) — Chimpanzees in Uganda have started eating clay to supplement the minerals in their diet, researchers report.

The clay consumed by the chimps in the Budongo forest also helps them “detox” and digest their food, the study authors added.

The scientists observed wild chimps in the forest eating and drinking from clay pits and termite mounds. This change in diet may be partly due to the widespread destruction of raffia palm trees that the chimps typically relied on for their minerals.

“Raffia is a key source of sodium, but to our surprise the sodium content was very low in the diet so this does not appear to be the main reason for the new clay-bingeing,” the study’s lead author, Vernon Reynolds, emeritus professor of biological anthropology at University of Oxford in England, said in a university news release.

“Instead, the wide range of minerals present in their diet suggests that clay is eaten as a general mineral supplement,” he added.

Findings from the study were published online July 28 in the journal PLoS One.

The study team observed the chimps using leaves like sponges. The chimps dipped the leaves in clay water and then squeezed the liquid out of the leaves with their tongues. They also used their fingers to take lumps of clay directly from the ground and then ate it.

An analysis of the clay showed it’s high in a number of minerals, but particularly aluminium. The chimps’ diet consists mainly of fruits and leaves and is high in tannins. The clay may provide a way for the chimps to neutralize the tannins, the researchers suggested.

The study authors noted that local women in Budongo often drink or eat forest clay mixed with water when they have stomach problems and during pregnancy.

Along with aluminium, the clay also contains sodium, calcium, iron, magnesium and potassium, according to the paper.

Too Much Facebook, Twitter Tied to Poor Mental Health in Teens

By Alan Mozes
HealthDay Reporter

FRIDAY, July 31, 2015 (HealthDay News) — Teens who frequently use social media are more likely to say they struggle with mental health concerns that are not being addressed, new Canadian research reveals.

At issue is the amount of time adolescents spend browsing and posting on sites such as Facebook, Twitter or Instagram.

“It is difficult to speculate what mechanisms may link the use of social networking sites to mental health problems,” said study author Dr. Hugues Sampasa-Kanyinga, from the department of epidemiology at Ottawa Public Health in Ottawa, Canada.

While the study did not prove a cause-and-effect link, Sampasa-Kanyinga noted that the “use of social networking sites can lead to poor mental health, and poor mental health may be a reason why youth use social networking sites. That said, it could be that kids with mental health problems are seeking out interactions as they are feeling isolated and alone. Or it could be that greater time online exposes one to more opportunities for cyberbullying, for instance.”

Sampasa-Kanyinga and study co-author Dr. Rosamund Lewis reported their findings online recently in the journal Cyberpsychology, Behavior, and Social Networking.

In the study, the researchers analyzed part of a youth health survey that tallied responses from more than 750 students who were enrolled in grades 7 through 12 (average age of 14) in Ottawa.

Just over a quarter said they accessed social networking sites for more than two hours every day, while about a fifth said they never did or did so rarely. More than half (54 percent) said they surfed such sites, but for two hours or less daily.

Nearly two-thirds described their mental health status as either “excellent” or “very good.” About a fifth said their mental state was “good,” while about 17 percent described it as “poor.”

In addition, about a quarter said they had mental health support needs that were going unmet, while the remainder said they were getting the help they felt they needed. About 13 percent said they had contemplated suicide.

Ultimately, the study authors determined that teens who accessed online sites two or more hours per day were more likely to describe their mental health as “poor” and less likely to have their own perceived needs for mental health support addressed.

High use of social networking was also linked to a higher risk for psychological distress and a higher likelihood for having had suicidal thoughts.

Sampasa-Kanyinga said some of the problem might lie in the anonymity of social networks, which boosts the risk for cyberbullying. Such sites also encourage teens to compare themselves to others, she noted, while making alcohol and cigarettes more appealing and accessible.

Nevertheless, she stressed that “everything is a matter of balance,” and cautioned against drawing a direct cause-and-effect link between social networking and poor mental health among teens.

“A simple use of social networking sites cannot fully explain by itself the occurrence of mental health problems,” Sampasa-Kanyinga said. “There are several factors that could interact to explain mental health outcomes,” she said, including substance use, bullying, body image and weight concerns, and family history and context.

That said, she advised parents to limit their child’s social networking time to under two hours a day, while remaining on the lookout for mood changes, dietary shifts, sleep issues and unusual behavior.

Scott Campbell, an associate professor of communication studies at the University of Michigan in Ann Arbor, described the study as “interesting,” while suggesting that the effort “actually raises more questions than it helps answer.”

Campbell, who was not involved with the study, pointed out that asking teens to quantify hours spent online is unreliable, given that Internet use — unlike, say, movies — is not easily measured in blocks of time. He also said that “the social implications of social network sites are highly dependent on how people use them, not just how much they use them.”

“Generally speaking,” Campbell said, “I would add that too much of anything is going to have negative implications, whether it be kale or social media.” But he said more research would be needed to develop “a more nuanced picture of how different uses of social network sites by youth are associated with mental health indicators.”

Regular, Moderate Coffee Drinking Tied to Better Brain Health in Seniors

FRIDAY, July 31, 2015 (HealthDay News) — A study of more than 1,400 Italian seniors finds links between patterns of coffee consumption and their risk for “mild cognitive impairment” — declines in memory and thinking that are often a precursor to dementia.

The study could only point to associations, not cause-and-effect, the investigators said. But prior research has suggested that caffeine might impact neurological health.

In the study, a team led by Dr. Vincenzo Solfrizzi of the University of Bari Aldo Moro, looked at the coffee consumption of 1,445 Italians aged 65 to 84. The participants’ mental health was also tracked for a median of three-and-a-half years.

Reporting earlier this week in the Journal of Alzheimer’s Disease, the research team found that people who consistently drank about one or two cups of coffee per day had a lower rate of mild cognitive impairment (MCI) than those who never or rarely drank the brew.

The beneficial association was not found among people whose habitual coffee intake exceeded two cups per day, Solfrizzi’s group added.

And in what they called an “interesting” finding, the researchers found that the rate of MCI actually rose over time for seniors who bumped up their daily intake by a cup of coffee or more daily. Those participants had a rate of MCI that was about one-and-a-half times higher than that of long-term, moderate coffee drinkers (one to two cups per day) whose daily intake didn’t increase.

The bottom line, according to the study authors: “Older individuals who never or rarely consumed coffee and those who increased their coffee consumption habits had a higher risk of developing MCI” compared to moderate coffee drinkers.

How might java influence brain health? According to the authors, mouse studies suggest that caffeine may have a “neuroprotective” effect in minimizing damage from the buildup of amyloid protein plaques — long linked to Alzheimer’s disease. And while “moderate” levels of caffeine have seemed to boost memory in rodents, higher doses may hinder it, Solfrizzi’s team said.

Moderate caffeine intake might also help the aging brain by boosting insulin sensitivity, cutting the odds for type 2 diabetes. Diabetes has long been linked to a higher risk for memory woes, the researchers said.

Still, more research is needed to strengthen the notion that one of the world’s favorite drinks might help ward off dementia.

“Larger studies with longer follow-up periods should be encouraged . . . so hopefully opening new ways for diet-related prevention of dementia and Alzheimer’s disease,” the Italian team concluded.

Noninvasive Stimulation Gets Legs Moving After Spinal Cord Injury

FRIDAY, July 31, 2015 (HealthDay News) — A noninvasive procedure might help people with paralysis move their legs without the need for surgery or implanted devices, new research suggests.

The treatment approach is called transcutaneous stimulation, where a device delivers an electrical current to the spine through electrodes placed on the outside of the lower back.

In a recent trial of the device, five paralyzed men were able to generate steplike movements. The men didn’t walk, but moved while their legs were suspended in braces hung from the ceiling. This enabled them to move without resistance from gravity.

“These encouraging results provide continued evidence that spinal cord injury may no longer mean a lifelong sentence of paralysis, and support the need for more research,” Dr. Roderic Pettigrew, director of the National Institute of Biomedical Imaging and Bioengineering, said in an institute news release.

These findings come on the heels of another successful study using spinal stimulation, but with a surgically implanted electrodes. Electrical stimulation with implanted electrodes allowed the men to voluntarily flex their toes, ankles and knees, and one man was even able to stand unassisted for short periods. The strength and precision of their movements improved over time with intense physical rehabilitation, according to that study, published in April 2014 in the journal Brain.

The latest study, however, focuses on a nonsurgical option.

“The potential to offer a life-changing therapy to patients without requiring surgery would be a major advance; it could greatly expand the number of individuals who might benefit from spinal stimulation. It’s a wonderful example of the power that comes from combining advances in basic biological research with technological innovation,” said Pettigrew.

The current study’s leader, V. Reggie Edgerton, a distinguished professor of integrative biology and physiology at University of California, Los Angeles, expressed similar thoughts.

“There are a lot of individuals with spinal cord injury that have already gone through many surgeries and some of them might not be up to or capable of going through another,” said Edgerton in the news release. “The other potentially high impact is that this intervention could be close to one-tenth the cost of an implanted stimulator.”

The men involved in the study were all paralyzed for at least two years. They underwent a 45-minute transcutaneous stimulation sessions on a weekly basis for about 18 weeks. While undergoing the stimulation, the men were periodically instructed to either try to move their legs or to remain passive.

In addition to the noninvasive stimulation, the men also received several minutes of conditioning. Their legs were moved for them in a steplike pattern.

During the final four weeks of the study, the men were also given the drug buspirone. The medication, which acts like serotonin, has been shown to promote movement in mice with spinal cord injuries.

When the study began, the men’s legs only moved if the stimulation was strong enough to trigger involuntary movements. During therapy, men who tried to move their legs even more developed a significantly wider range of movement, the study found.

After four weeks of both therapy and physical training, the men’s voluntary range of motion doubled while receiving the stimulation. Researchers explained that the treatment worked by reactivating dormant connections between the brain and the spine.

Recordings of electrical signals in the men’s leg muscles increased while the amount of stimulation remained the same, suggesting communication between the brain and spine was being reestablished.

“It’s as if we’ve reawakened some networks so that once the individuals learned how to use those networks, they become less dependent and even independent of the stimulation,” Edgerton said.

By the end of the study, with the medication, the men were able to move their legs with no stimulation at all. On average, their range of motion was the same as when they were moving while receiving stimulation.

Findings from the study were published July 30 in the Journal of Neurotrauma.

The study authors plan to conduct more research to determine if noninvasive spinal stimulation could enable paralyzed patients to bear their own weight the way people with surgically implanted devices can. In addition, they want to investigate if this noninvasive therapy can also help people regain the ability to sweat, regulate blood pressure and control bladder, bowel and sexual function.

The researchers also hope to learn if this external stimulation can help those who are partially paralyzed.

Despite the promise of noninvasive spinal cord stimulation, the researchers said surgically implanted devices may still be needed by some patients.
