Athletes Often Suffer A Concussion.
Altitude may wear an athlete's endanger of concussion, according to a new study believed to be the before to examine this association. High school athletes who conduct at higher altitudes suffer fewer concussions than those closer to blue water level, researchers found in Dec, 2013. One workable reason is that being at a higher altitude causes changes that seduce the brain fit more tightly in the skull, so it can't move around as much when a better suffers a head blow hgh. The investigators analyzed concussion statistics from athletes playing a line up of sports at 497 US great in extent schools with altitudes ranging from 7 feet to more than 6900 feet above heap level.
The average altitude was 600 feet. They also examined football separately, since it has the highest concussion clip of US gamy school sports. At altitudes of 600 feet and above, concussion rates in all drunk drill sports were 31 percent lower, and were 30 percent condescend for football players, according to the findings recently published in the Orthopaedic Journal of Sports Medicine.

An Effect Of Hormone Therapy On Breast Cancer
An Effect Of Hormone Therapy On Breast Cancer.
Although several enormous studies in just out years have linked the use of hormone remedy after menopause with an increased imperil of breast cancer, the authors of a new analysis claim the demonstrate is too limited to confirm the connection. Dr Samuel Shapiro, of the University of Cape Town Medical School in South Africa, and his colleagues took another mien at three huge studies that investigated hormone remedial programme and its possible health risks - the Collaborative Reanalysis, the Women's Health Initiative (WHI) and the Million Women Study our site. Together, the results of these studies found overall an increased danger of tit cancer surrounded by women who used the combination fashion of hormone therapy with both estrogen and progesterone.
Women who have had a hysterectomy and use estrogen-only cure also have an increased risk, two of the studies found. The WHI, however, found that estrogen-only psychotherapy may not increase breast cancer jeopardy and may actually decrease it, although that has not been confirmed in other research. After the WHI look was published in July 2002, women dropped hormone psychoanalysis in droves.
Many experts pointed to that worsening in hormone therapy use as the reason breast cancer rates were declining. Not so, Shapiro said: "The run out of gas in heart cancer incidence started three years before the go to ruin in HRT use commenced, lasted for only one year after the HRT decline commenced, and then stopped". For instance between 2002 and 2003, when heavy-set numbers of women were still using hormone therapy, the number of new chest cancer cases fell by nearly 7 percent.
In taking a appear at the three studies again, Shapiro and his team reviewed whether the affirmation satisfied criteria important to researchers, such as the strength of an association, taking into estimation other factors that could influence risk. Their conclusion: The averment is not strong enough to say definitively that hormone therapy causes core cancer. The study is published in the current exit of the Journal of Family Planning and Reproductive Health Care.

Testing A New Experimental Drug To Raise Good Cholesterol Level
Testing A New Experimental Drug To Raise Good Cholesterol Level.
An theoretical poison that raises HDL, or "good," cholesterol seems to have passed an primary block by proving safe in preliminary trials. Although the provisional was primarily designed to look at safety, researchers scheduled to gift the finding Wednesday at the American Heart Association's annual joining in Chicago also report that anacetrapib raised HDL cholesterol by 138 percent and eschew LDL, HDL's infelicitous twin, almost in half arab xnxx. "We saw very encouraging reductions in clinical events," said Dr Christopher Cannon, clue maker of the study, which also appears in the Nov 18, 2010 progeny of the New England Journal of Medicine.
A big study to support the results would take four to five years to complete so the numb is still years away from market who is a cardiologist with Brigham and Women's Hospital in Boston. Other experts are intrigued by the findings, but note that the dig into is still in very inopportune stages. "There are a lot of people in the prevention/lipid field that are simultaneously agitated and leery," said Dr Howard Weintraub, clinical principal of the Center for the Prevention of Cardiovascular Disease at NYU Langone Medical Center in New York City.
Added Dr John C LaRosa, president of the State University of New York (SUNY) Downstate Medical Center in New York City: "It's very prelude but it's impressive because the carry on psychedelic out of the barrel of this variety was not a success. This looks like a better drug, but it's not ultimate by any means. Don't take this to the bank".
LaRosa was referring to torcetrapib, which, in the manner of anacetrapib, belongs to the category of drugs known as cholesterol ester transfer protein (CETP) inhibitors. A gargantuan trial on torcetrapib was killed after investigators found an increased peril of death and other cardiovascular outcomes. "I would be more frenetic about anacetrapib if I hadn't seen what happened to its cousin torcetrapib. Torcetrapib raised HDL astoundingly but that was in all respects neutralized by the enlarge in cardiovascular events".

Doctors Discovered How The Brain Dies
Doctors Discovered How The Brain Dies.
Shrunken structures at bottom the brains of weighed down marijuana users might describe the stereotype of the "pothead," brain researchers report. Northwestern University scientists studying teens who were marijuana smokers or past smokers found that parts of the imagination related to working thought appeared diminished in size - changes that coincided with the teens' on one's uppers performance on memory tasks missouri. "We observed that the shapes of thought structures related to short-term memory seemed to come to naught inward or shrink in people who had a history of regular marijuana use when compared to healthy participants," said study framer Matthew Smith.
He is an assistant research professor in psychiatry and behavioral sciences at the Northwestern University Feinberg School of Medicine, in Chicago. The shrinking of these structures appeared to be more advanced in men and women who had started using marijuana at a younger age. This suggests that youngsters might be more reachable to drug-related celebration loss, according to the study, which was published in the Dec 16. 2013 emanation of the quarterly Schizophrenia Bulletin.
So "The brains abnormalities we're observing are directly allied to poor short-term memory performance. The more that intellect looks abnormal, the poorer they're doing on memory tests". The typescript is provocative because the participants had not been using marijuana for a couple years, indicating that recall problems might persist even if the person quits smoking the drug, said Dr Frances Levin, chairman of the American Psychiatric Association's Council on Addiction Psychiatry. At the same time, Levin cautioned that the exegesis presents a chicken-or-egg problem.
It's not sparkling whether marijuana use caused the respect problems or kin with reminiscence problems tended to use marijuana. "The big $64000 question is whether these recollection problems predate the marijuana use". The scrutinize focused on nearly 100 participants sorted into four groups: bracing people who never used pot, healthy people who were former excessive pot smokers, people with schizophrenia who never used bank and schizophrenics who were former heavy pot users. Researchers worn MRI scans to study the structure of participants' brains.
