In Most Cases, A Cough Caused By Viruses, And Antibiotics To Treat It Impractical

In Most Cases, A Cough Caused By Viruses, And Antibiotics To Treat It Impractical.
You've been hacking and coughing for a week now - isn't it spell that the cough was through? Sadly, the rebutter is often "no," and experts gunfire that many citizenry have a mistaken idea of how long an acute cough should last. This misconception can lead to the disposable (and, for public safety, dangerous) overuse of antibiotics, a new study finds. "No one wants or likes a persistent cough.

Patients simply want to get rid of it," said Dr Robert Graham, an internist at Lenox Hill Hospital in New York City. "After strenuous over-the-counter regimens for about a week, they descend upon their doctors with the hopes of obtaining a prescription antibiotic for a self-limited ready that is usually caused by viruses," which do not respond to antibiotics who was not involved in the new study.

So how sustained does the average acute cough really last? The team of researchers from the University of Georgia, in Athens, reviewed medical brochures and found that the average duration of an acute cough is nearly three weeks (17,8 days). They then surveyed nearly 500 adults and found that they reported that their cough lasted an ordinary of seven to nine days. And if a philosophical believes an acute cough should last about a week, they are more liable to ask their doctor for antibiotics after five to six days of having a cough, the researchers noted.

Perspective Eliminate The Deficit For Lung Transplantation

Perspective Eliminate The Deficit For Lung Transplantation.
A replacement in medical procedures could greatly slacken up and possibly eliminate the shortage of lungs available for transplant, US experts and an Italian muse about suggest. The procedure - carefully controlling the supply of air and pressure inside the lungs of brain-dead patients on ventilators - nearly doubled the tot of lungs that were able to be transplanted to save the lives of others, the study found. The United States has a paucity of lungs, as well as other organs, available for donation. People needing a lung resettle wait an average of more than three years, according to the United Network for Organ Sharing (UNOS). In 2009, 2234 the crowd were added to the waiting list, according to the Organ Procurement and Transplantation Network (OPTN).

One saneness for the shortage is that lungs are "finicky" and easily damaged while comatose patients are on ventilators, said Dr Phillip Camp, superintendent of the lung transplant program at Brigham and Women's Hospital in Boston and chairman of the UNOS-OPTN operations and cover committee. But more carefully controlling how much appearance is pushed into the lungs by ventilators and maintaining pressure inside the lungs during such procedures as apnea tests, to interruption breathing, improves lung viability dramatically, according to the study.

And "They found astonishing increases in the availability of viable lungs using this lung preservation strategy," said Dr Mark S Roberts, chairman of the fettle policy and management department at the University of Pittsburgh and novelist of an editorial accompanying publication of the study in the Dec 15, 2010 issue of the Journal of the American Medical Association. The bookwork involved 118 brain-dead patients with otherwise normal lung function.

One rank was given conventional ventilation, including relatively high volumes of air pumped in from the ventilator and disconnection of the ventilator during apnea tests, allowing the lungs to deflate. The others were given supposed "protective" ventilation. That drill included less air volume, higher "positive end-expiratory coerce levels," which meant increasing the air pressure in the lungs near the end of expiration to advocate pressure, and the use of continuous positive airway pressure during various medical procedures and tests, which does not allow the lungs to entirely deflate.

About 95 percent of those in the protective ventilation group met the criteria to become lung donors, compared with 54 percent of those treated conventionally. About 54 percent of the vigilant set actually became donors, compared with 27 percent in the conventional group.

Malignant Brain Tumors In Children Will Soon Be Able To Be Curable

Malignant Brain Tumors In Children Will Soon Be Able To Be Curable.
A advance inquiry has found that a targeted treatment for medulloblastoma - the most non-private malignant brain cancer in children - may one day be able to treat drug-resistant forms of the disease. "Less than 5 percent of patients currently subsist medulloblastoma," said Dr Amar Gajjar, be conducive to author of the study, which was presented Saturday at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago. "Most patients as per usual die 12 to 18 months after the tumor comes back".

Although this scan was designed primarily to assess stand effects, if the drug moves through the pharmaceutical pipeline, it would be the first targeted drug aimed at a signaling pathway. Chemotherapy is the pure treatment now. The drug, known as GDC-0449, interrupts the "sonic hedgehog" pathway, which has been implicated in a bunch of other cancers; it is involved in 20 percent of cases of children with medulloblastoma.

Vaccination Against H1N1 Flu Also Protects From The 1918 Spanish Influenza

Vaccination Against H1N1 Flu Also Protects From The 1918 Spanish Influenza.
The H1N1 influenza vaccine distributed in 2009 also appears to cover against the 1918 Spanish influenza virus killed more than 50 million kinfolk nearly a century ago, budding examination in mice reveals. The finding stems from work funded by the US National Institute of Allergy and Infectious Diseases, fragment of the National Institutes of Health, which examined the vaccine's efficacy in influenza care among mice.

And "While the reconstruction of the formerly ancient Spanish influenza virus was important in helping study other pandemic viruses, it raised some concerns about an random lab release or its use as a bioterrorist agent," study author Adolfo Garcia-Sastre, a professor of microbiology at the Mount Sinai School of Medicine in New York City, said in a creed front-page news release. "Our research shows that the 2009 H1N1 influenza vaccine protects against the Spanish influenza virus, an high-level breakthrough in preventing another devastating pandemic like 1918". Garcia-Sastre and his colleagues shot their findings in the current issue of Nature Communications.

Hairdressers Against AIDS

Hairdressers Against AIDS.
Could the banning of HIV infection and AIDS be a comb, balls up and blow-dry away? That's the idea behind an innovative new national outreach effort, Hairdressers Against AIDS, which got its throw Tuesday at the United Nations in New York City, forward of Dec 1, 2010, World AIDS Day. The initiative - described as "one of the largest HIV/AIDS mobilization campaigns in US history" - has locks carefulness giant L'Oreal joining forces with nonprofits such as the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Global Business Coalition on HIV/AIDS, TB and Malaria (GBC). The ambition is to empower America's 500000-plus trifle stylists to use the relationships they have with millions of clients for salon-based chats on the how, why and what of HIV.

So "Today there is no vaccine," famed GBC president and CEO John Tedstrom, speaking to 500 hairdressers who'd gathered at the UN for the launch. "There is no cure. We're getting there. But today there is only information. The more we talk, the more we educate, the more we nip in the bud the apply of this epidemic".

And "You'll witness millions of people hearing about HIV from people that they know. They'll be hearing compelling time-tested messages about HIV prevention, and they'll be able to take those messages back to their physical relationships. And then whether it's a mom talking to her daughter or a girlfriend talking to her boyfriend, it doesn't matter. We'll be able to have an mature conversation about HIV and sexual health".

Using hair-care professionals to get constitution messages out to the masses isn't a novel idea. Recent studies have shown, for example, that criminal men can be motivated by barbershop messages to improve their blood pressure or get educated about their imperil for prostate cancer. And the US launch of Hairdressers Against AIDS is just the latest extensiveness of a global HIV awareness effort that's already in place in 30 countries throughout the world.

A New Drug From Sea Sponge For The Treatment Of Severe Breast Cancer

A New Drug From Sea Sponge For The Treatment Of Severe Breast Cancer.
A reborn chemotherapy treat made from a main sponge extended the lives of women with metastatic breast cancer by about 2,5 months, researchers report. The propitious finding on the drug, known as eribulin, was presented Sunday at the annual convention of the American Society of Clinical Oncology in Chicago. "We have a major need for redone therapies," noted study author Dr Christopher Twelves. "We see a statistically significant service in overall survival in a situation where we rarely see this sort of improvement".

So "Eribulin targets the mechanisms by which the cells divide, which is distinct from previous agents," explained Twelves, who is a professor of clinical cancer pharmacology and oncology and culmination of the Clinical Cancer Research Groups at the Leeds Institute of Molecular Medicine and St James' Institute of Oncology in Leeds, UK. More than 750 women were randomized to undergo either eribulin or a "treatment of physician's choice," the continue because there isn't a standard care for this type of cancer. In almost all cases, it was another chemotherapy.

The study included women who had already been treated extensively for their cancer, with the standard patient already having undergone four chemotherapies. The researchers description a 23 percent improvement in median survival when women took eribulin, with the median survival for those in the eribulin assemblage at just over 13 months vs 10,7 months in the treatment-of -choice group. "These results potentially found eribulin as a new and effective treatment for women with heavily pretreated titty cancer," said Twelves, who disclosed financial ties with Eisai, which makes eribulin.

Also featured at the congress Sunday, Italian researchers report that liver biopsies can disclose whether a breast cancer that has spread through the body has changed its cellular characteristics, such as estrogen-receptor status, progesterone-receptor prominence or HER2 status. These tumor properties often dictate the type of treatment a woman receives, import that some women may benefit from switching therapy if the characteristics of their cancer change.

Diverting A Nurse In The Preparation Of Medicines Increases The Risk Of Errors

Diverting A Nurse In The Preparation Of Medicines Increases The Risk Of Errors.
Distracting an airline cicerone during taxi, takeoff or splashdown could be conducive to to a critical error. Apparently the same is true of nurses who prepare and administer medication to medical centre patients. A new study shows that interrupting nurses while they're tending to patients' medication needs increases the chances of error.

As the total of distractions increases, so do the number of errors and the peril to patient safety. "We found that the more interruptions a nurse received while administering a drug to a indicated patient, the greater the risk of a serious error occurring," said the study's lead author, Johanna I Westbrook, commander of the Health Informatics Research and Evaluation Unit at the University of Sydney in Australia.

For instance, four interruptions in the run of a single drug administration doubled the strong that the patient would experience a major mishap, according to the study, reported in the April 26 scion of the Archives of Internal Medicine. Experts say the study is the first to show a clear association between interruptions and medication errors.

It "lends material evidence to identifying the contributing factors and circumstances that can captain to a medication error," said Carol Keohane, program director for the Center of Excellence for Patient Safety Research and Practice at Brigham and Women's Hospital in Boston. "Patients and forefathers members don't appreciate that it's dangerous to patient safety to interrupt nurses while they're working," added Linda Flynn, affiliated professor at the University of Maryland School of Nursing in Baltimore. "I have seen my own group members go out and interrupt the nurse when she's standing at a medication also waggon to ask for an extra towel or something else inappropriate".

Julie Kliger, who serves as program director of the Integrated Nurse Leadership Program at the University of California, San Francisco, said that administering medication has become so unvarying that the whole world involved - nurses, health-care workers, patients and families -- has become complacent. "We needfulness to reframe this in a new light, which is, it's an important, ticklish function. We need to give it the respect that it is due because it is high volume, high risk and, if we don't do it right, there's self-possessed harm and it costs money".

Losing Excess Weight May Help Middle-Aged Women To Reduce The Unpleasant Hot Flashes Accompanying Menopause

Losing Excess Weight May Help Middle-Aged Women To Reduce The Unpleasant Hot Flashes Accompanying Menopause.
Weight damage might helper middle-aged women who are overweight or stout reduce bothersome hot flashes accompanying menopause, according to a redone study. "We've known for some time that obesity affects hot flashes, but we didn't identify if losing weight would have any effect," said Dr Alison Huang, the study's author. "Now there is esteemed evidence losing weight can reduce hot flashes".

Study participants were part of an intensified lifestyle-intervention program designed to help them lose between 7 percent and 9 percent of their weight. Huang, aide-de-camp professor of obstetrics and gynecology at the University of California, San Francisco, said the findings could produce women with another reason to take control of their weight. "The message here is that there is something you can do about it (hot flashes)".

About one third of women sustain hot flashes for five years or more last menopause, "disrupting sleep, interfering with work and leisure activities, and exacerbating anxiety and depression," according to the study. The women in the research group met with experts in nutrition, exercise and behavior weekly for an hour and were encouraged to utilization at least 200 minutes a week and reduce caloric intake to 1200-1500 calories per day. They also got relief planning menus and choosing what kinds of foods to eat.

Women in a switch group received monthly group education classes for the earliest four months. Participants, including those in the control group, were asked to respond to a survey at the beginning of the contemplation and six months later to describe how bothersome hot flashes were for them in the past month on a five-point ranking with answers ranging from "not at all" to "extremely".

They were also asked about their daily exercise, caloric intake, and psychotic and physical functioning using instruments widely accepted in the medical field, said Huang. No correlation was found between any of these and a reduction in bosh flashes, but "reduction in weight, body mass index finger (BMI), and abdominal circumference were each associated with improvements" in reducing hot flashes, according to the study, published in the July 12 child of Archives of Internal Medicine.

New Researches In Autism Treatment

New Researches In Autism Treatment.
Black and Hispanic children with autism are markedly less plausible than children from ghastly families to receive specialty care for complications tied to the disorder, a imaginative study finds in June 2013. Researchers from Massachusetts General Hospital for Children in Boston found that the rates at which minority children accessed specialists such as gastroenterologists, neurologists and psychiatrists, as well as the tests these specialists use, ran well below those of snowy children. "I was surprised not by the trends, but by how significant they were," said muse about writer Dr Sarabeth Broder-Fingert, a fellow in the department of pediatrics at MassGeneral and Harvard Medical School.

And "Based on my own clinical undergo and some of the literature that exists on this, I intelligence we'd probably see some differences between white and non-white children in getting specialty mindfulness - but some of these differences were really large, especially gastrointestinal services". The study is published online June 17, 2013 in the daily Pediatrics.

According to the US Centers for Disease Control and Prevention, about one in 50 school-age children has been diagnosed with an autism spectrum disorder, a circle of neurodevelopmental problems signal by impairments in social interaction, communication and restricted interests and behaviors. Research has indicated that children with an autism spectrum fuss have higher odds of other medical complications such as seizures, forty winks disorders, attention-deficit/hyperactivity disorder (ADHD), anxiety and digestive issues.

In the new study, Broder-Fingert and her group examined data from more than 3600 autism patients aged 2 to 21 over a 10-year span. The endless majority of patients were white, while 5 percent were unconscionable and 7 percent were Hispanic. About 1500 of the autism patients had received specialty care.

New Study On Prevention Of Transfer Of HIV

New Study On Prevention Of Transfer Of HIV.
An antiviral numb may assist protect injection drug users from HIV infection, a restored study finds. The study of more than 2400 injection drug users recruited at 17 remedy treatment clinics in Thailand found that daily tablets of tenofovir reduced the risk of HIV infection by nearly 49 percent, compared to quiescent placebo pills. One expert said an intervention to worker shield injection drug users from HIV - the virus that causes AIDS - is much needed.

And "This is an mighty study that opens up an additional option for preventing HIV in a hard-to-reach population," said Dr Joseph McGowan, medical official at the Center for AIDS Research and Treatment at North Shore University Hospital in Manhasset, NY. He famed that "HIV infections persist to occur at high rates, with over 2,5 million worldwide and 50000 renewed infections in the US each year. This is despite widespread knowledge about HIV infection and the mode it is spread, through unprotected sex and sharing needles for injecting drugs".

The participants included in the changed study were followed for an average of four years. During that time, 17 of the more than 1200 patients taking tenofovir became infected with HIV, compared with 33 of an comparable number of patients taking a placebo, according to the con published online June 12, 2013 in The Lancet. Further analyses of the results showed that the sheltering effect of tenofovir was highest among those who most closely followed the drug's prescribed regimen.

In this group, the danger of HIV infection was reduced by more than 70 percent, said study leaders Dr Kachit Choopanya and Dr Michael Martin, supervisor of clinical research for the Thailand Ministry of Public Health-US Centers for Disease Control and Prevention Collaboration. Prior inspect has shown that hindering use of antiviral drugs cuts the risk of sexual transmission of HIV in both heterosexual couples and men who have union with men, and also reduces mother-to-child transmission of HIV.

Menopause Affects Women Differently

Menopause Affects Women Differently.
Women bothered by sensual flashes or other belongings of menopause have a number of treatment options - hormonal or not, according to updated guidelines from the American College of Obstetricians and Gynecologists. It's estimated that anywhere from 50 percent to 82 percent of women thriving through menopause have simmering flashes - sudden feelings of extreme impetuosity in the upper body - and night sweats. For many, the symptoms are frequent and severe enough to cause beauty sleep problems and disrupt their daily lives.

And the duration of the misery can last from a couple years to more than a decade, says the college, the nation's unrivalled group of ob/gyns. "Menopausal symptoms are common, and can be very bothersome to women," said Dr Clarisa Gracia, who helped correspond the new guidelines. "Women should be aware that effective treatments are available to address these symptoms". The guidelines, published in the January problem of Obstetrics andamp; Gynecology, reinforce some longstanding advice: Hormone therapy, with estrogen unassisted or estrogen plus progestin, is the most effective way to cool hot flashes.

But they also offer out the growing evidence that some antidepressants can help an associate professor of obstetrics and gynecology at the University of Pennsylvania in Philadelphia. In studies, unhappy doses of antidepressants such as venlafaxine (Effexor) and fluoxetine (Prozac) have helped rescue hot flashes in some women. And two other drugs - the anti-seizure sedative gabapentin and the blood pressure medication clonidine - can be effective, according to the guidelines.

So far, though, only one non-hormonal deaden is actually approved by the US Food and Drug Administration for treating bright flashes: a low-dose version of the antidepressant paroxetine (Paxil). And experts said that while there is witness some hormone alternatives ease hot flashes, none works as well as estrogen and estrogen-progestin. "Unfortunately, many providers are nervous to prescribe hormones.

And a lot of the time, women are fearful," said Dr Patricia Sulak, an ob/gyn at Scott andamp; White Hospital in Temple, Texas, who was not knotty in letters the new guidelines. Years ago, doctors routinely prescribed hormone replacement remedy after menopause to lower women's risk of heart disease, among other things. But in 2002, a big US trial called the Women's Health Initiative found that women given estrogen-progestin pills in point of fact had slightly increased risks of blood clots, heart attack and breast cancer. "Use of hormones plummeted" after that.

Risk Factors For Alzheimer's Disease

Risk Factors For Alzheimer's Disease.
Older adults with respect problems and a days of yore of concussion have more buildup of Alzheimer's disease-associated plaques in the brain than those who also had concussions but don't have celebration problems, according to a new study. "What we think it suggests is, head trauma is associated with Alzheimer's-type dementia - it's a danger factor," said study researcher Michelle Mielke, an colleague professor of epidemiology and neurology at Mayo Clinic Rochester. But it doesn't refer to someone with head trauma is automatically going to develop Alzheimer's. Her over is published online Dec 26, 2013 and in the Jan 7, 2014 print go forth of the journal Neurology.

Previous studies looking at whether head trauma is a risk factor for Alzheimer's have come up with conflicting results. And Mielke stressed that she has found only a connect or association, not a cause-and-effect relationship. In the study, Mielke and her body evaluated 448 residents of Olmsted County, Minn, who had no signs of thought problems.

They also evaluated another 141 residents with memory and thinking problems known as mild cognitive impairment. More than 5 million Americans have Alzheimer's disease, according to the Alzheimer's Association. Plaques are deposits of a protein explode known as beta-amyloid that can construct up in between the brain's nerve cells. While most consumers develop some with age, those who develop Alzheimer's generally get many more, according to the Alzheimer's Association.

They also wait on to get them in a predictable pattern, starting in brain areas crucial for memory. In the Mayo study, all participants were old 70 or older. The participants reported if they ever had a brain injury that concerned loss of consciousness or memory. Of the 448 without any memory problems, 17 percent had reported a understanding injury. Of the 141 with memory problems, 18 percent did.

Patients With Cancer Choose Surgery

Patients With Cancer Choose Surgery.
People with hold cancer who suffer surgery before receiving radiation treatment fare better than those who start treatment with chemotherapy, according to a small brand-new study. Many patients may be hesitant to begin their treatment with an invasive procedure, University of Michigan researchers noted. But advanced surgical techniques can benefit patients' chances for survival, the authors well-known in a university news release. The study was published online Dec 26, 2013 in JAMA Otolaryngology Head and Neck Surgery.

Nearly 14000 Americans will be diagnosed with vernacular cancer this year and 2,070 will cash in one's chips from the disease, according to the American Cancer Society. "To a unsophisticated person with tongue cancer, chemotherapy may sound like a better option than surgery with extensive reconstruction," investigation author Dr Douglas Chepeha, a professor of otolaryngology-head and neck surgery at the University of Michigan Medical School, said in the advice release. "But patients with oral opening cancer can't tolerate induction chemotherapy as well as they can handle surgery with follow-up radiation".

And "Our techniques of reconstruction are advanced and make patients better survival and functional outcomes". The reading involved 19 people with advanced oral cavity mouth cancer. All of the participants were given an approve dose of chemotherapy (called "induction" chemotherapy). Patients whose cancer was reduced in enormousness by 50 percent received more chemotherapy as well as radiation therapy.

New Treatments For Asthma

New Treatments For Asthma.
Researchers reply they've discovered why infants who tangible in homes with a dog are less likely to develop asthma and allergies later in childhood. The span conducted experiments with mice and found that exposing them to dust from homes where dogs live triggered changes in the community of microbes that material in the infant's gut and reduced immune system answer to common allergens. The scientists also identified a specific species of gut bacteria that's important in protecting the airways against allergens and viruses that cause respiratory infections, according to the study published online Dec 16, 2013 in the Proceedings of the National Academy of Sciences.

While these findings were made in mice, they're also odds-on to interpret why children who are exposed to dogs from the time they're born are less seemly to have allergies and asthma, the University of California, San Francisco (UCSF) and University of Michigan researchers said. These results also suggest that changes in the sack bacteria community (gut microbiome) can impress immune function elsewhere in the body, said study co-leader Susan Lynch, an accessory professor in the gastroenterology division at UCSF.

Painkillers Tablets To Prevent Cancer

Painkillers Tablets To Prevent Cancer.
The medicament painkiller Celebrex might domestic prevent non-melanoma skin cancers, a small study suggests. But one dab hand was quick to note that the drug, which is most commonly used to counter the pain of arthritis, has been linked in some studies to an extend in the risk for cardiovascular problems. So it isn't yet clear that Celebrex (celecoxib) is an ideal alternative to prevent cancers that could be treated by other means. "We have a lot of different treatments for non-melanoma skin cancers," well-known Dr Doris Day, a dermatologist at Lenox Hill Hospital in New York City. "I would want more advice regarding the mechanism of action of Celebrex, because of the other risks".

The report, funded by the US National Cancer Institute and Pfizer, the maker of Celebrex, is published in the Nov 29, 2010 online issue and the Dec 15, 2010 lithograph issue of the Journal of the National Cancer Institute. Non-melanoma coating cancers are common, comprising "the most prevalent malignancies in the United States with an frequency equivalent to all other cancers combined," according to study lead author Dr Craig A Elmets, a professor of dermatology at the University of Alabama at Birmingham. These tumors take in basal chamber and squamous cell carcinomas of the skin, which are typically linked to overexposure to UV rays from the Sol or indoor tanning booths.

Currently, there are no US Food and Drug Administration (FDA)-approved agents for the halt of non-melanoma skin cancers, although sunscreens are widely recommended for this purpose. "However, even sunscreens are only modestly operational at preventing non-melanoma skin cancers. The demo that celecoxib can prevent these common malignancies heralds an entirely new approach for the prevention of these banal malignancies".

With Each Passing Day The World Becomes More Obese Kids

With Each Passing Day The World Becomes More Obese Kids.
American kids are chic obese, or nearly so, at an increasingly callow age, with about one-third of them falling into that sphere by the time they're 9 months old, researchers have found. There are some caveats about the research, however. The infants were not conscious recently: They were born about a decade ago. And it's not unblemished how excess weight in babies may affect their health later in their lives.

The survey found no guarantee that a baby who's overweight at 9 months will stay spineless when his or her second birthday rolls around. Still, the study - in the January-February 2011 efflux of the American Journal of Health Promotion - does present a picture of babies and infants who are carrying around a lot of reserve weight.

The findings also suggest that small changes in an infant's diet can make a big difference, said Dr Wendy Slusser, medical head of a children's weight program at Mattel Children's Hospital at the University of California, Los Angeles. For criterion "if you don't give your kid extract and have them eat the fruit instead, suddenly there's 150 calories less a day that can designate a big difference in weight gain over a long term".

The researchers examined federal data about 16400 children in the United States who were born in 2001. After adjusting the statistics so they wouldn't be thrown off by such factors as hilarious numbers of undisputed kinds of kids, the study authors found that 17 percent of 9-month-olds were fleshy and 15 percent were at risk for obesity, for a total of 32 percent.

Frequent Brain Concussion Can Lead To Suicide

Frequent Brain Concussion Can Lead To Suicide.
When ci-devant National Football League big name linebacker Junior Seau killed himself last year, he had a catastrophic mastermind disorder probably brought on by repeated hits to the head, the US National Institutes of Health has concluded. The NIH scientists who conscious Seau's brain constant that he had chronic traumatic encephalopathy (CTE). They told the Associated Press on Thursday that the cellular changes they dictum were similar to those found in autopsies of people "with exposure to repetitive head injuries".

The fight - characterized by impulsivity, depression and erratic behavior - is only diagnosed after death. Seau, 43, who played pro football for 20 seasons before his retirement in 2009, discharge himself in the strongbox last May 2012. His family donated his brain for research.

Some experts shadowy - but can't prove - that CTE led to Seau's suicide. "Chronic painful encephalopathy is the thing we have typically seen in a lot of the athletes," said Dr Howard Derman, commandant at the Methodist Concussion Center in Houston. "Rather than say 'this caused this,' I dream the observation is that there have been multiple pro football players now who have committed suicide: Dave Duerson, Andre Waters, John Grimsley - although Grimsley was just reported as a gun accident".

Some say that these players became depressed once they were out of the limelight or because of marital or economic difficulties, but Derman thinks the evidence goes beyond that."Yes, all that may be accepted on - but it still remains that the majority of these players who have committed suicide do have changes of chronic disturbing encephalopathy. We feel that that is also playing a role in their mental state".

But, Derman cautioned, "I can't for instance that chronic traumatic encephalopathy causes players to commit suicide". Chronic harmful encephalopathy was first noticed in boxers who suffered blows to the head over many years. In late years, concerns about CTE have led high school and college programs to circumscribe hits to the head, and the National Football League prohibits helmet-to-helmet hits.

Even Easy Brain Concussion Can Lead To Serious Consequences

Even Easy Brain Concussion Can Lead To Serious Consequences.
Soldiers who diminished meek brain injuries from blasts have long-term changes in their brains, a minuscule new study suggests. Diagnosing mild brain injuries caused by explosions can be challenging using principle CT or MRI scans, the researchers said. For their study, they turned to a unique type of MRI called diffusion tensor imaging. The technology was used to assess the brains of 10 American veterans of the wars in Iraq and Afghanistan who had been diagnosed with compassionate upsetting brain injuries and a comparison group of 10 people without brain injuries.

The average adjust since the veterans had suffered their brain injuries was a little more than four years. The researchers found that the veterans and the kinship group had significant differences in the brain's white matter, which consists mostly of signal-carrying nerve fibers. These differences were linked with distinction problems, delayed memory and poorer psychomotor examine scores among the veterans. "Psychomotor" refers to movement and muscle ability associated with mentally ill processes.

Skiing Prolongs Life

Skiing Prolongs Life.
Hitting the slopes soon? A late research suggests that's a good idea, because skiing and snowboarding holidays can boost your overall happiness. Researchers surveyed 279 visitors at three bigger ski resorts in South Korea. Of those people, 126 were skiers, 112 were snowboarders and 41 did both. Participants done in an customary of 4,5 days at a resort, and 90 percent visited ski resorts less than five times a season.

Frequent Consumption Of Energy Drinks May Cause A Failure Of The Heart

Frequent Consumption Of Energy Drinks May Cause A Failure Of The Heart.
Energy drinks rise blood strength and may make the pity more susceptible to electrical short circuits, new research suggests. But it's not clear-cut how much of this effect on blood pressure has to do with caffeine, which also is found in coffee, or whether the effect significantly raises the risk of heart problems. So should you put down your Red Bull or Monster Energy Drink? Not necessarily, experts say. "I have no honest disturb that having an energy drink or two will negatively impact most people's health," said Dr C Michael White, a professor and headman of pharmacy habit at the University of Connecticut.

He has studied energy drinks and is familiar with the new review's findings. However "there is enough gen in this meta-analysis to make me concerned that there may be pockets of the population who may have an increased risk of adverse events, and more pan out needs to be done to see if this is true". In other words, it's possible that some society could be especially vulnerable to the effects of energy drinks.

At issue are the caffeine-laden drinks that have become popular among bodies looking to stay alert, stay awake or get a jolt. Sixteen-ounce cans of drinks counterpart Monster Energy Assault and Rockstar pack in about 160 milligrams of caffeine, compared with violently 100 milligrams in a 6-ounce cup of coffee. Energy drinks also come with other ingredients like sugar and herbs, and medical experts have warned that they can omen trouble.

Industry representatives defend energy drinks, saying they carry about as much caffeine by the ounce as coffeehouse drinks. But people often consume much more of the forcefulness drinks at one time. In the new report, researchers looked at seven studies. Among them, a downright of 93 participants drank energy drinks and had their "QT interval" measured, while another 132 underwent blood persuade measurement.
