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.

Prolonged Use Of Statins Does Not Increase The Risk Of Cancer

Prolonged Use Of Statins Does Not Increase The Risk Of Cancer.
New dig into supports the whimsy that patients who clear cholesterol-lowering drugs known as statins may not have an increased chance for cancer, as some previous studies suggested. Statins are the most commonly prescribed drugs for populace with pongy blood cholesterol levels, which are linked to heart disease. Brand names cover Crestor, Lipitor and Zocor how to get my breast firm. "Three or four years ago there was a brilliance of articles pointing out that statins could deliver cancer, and, at present, the most recent studies do not show this, and this is one of them," said Dr Valentin Fuster, lifetime president of the American Heart Association and top dog of Mount Sinai Heart in New York City.

This modern development study, slated for award Wednesday at the annual meeting of the American Heart Association in Chicago, was conducted by researchers from S2 Statistical Solutions, Inc, a suite that does trade research for health care-related businesses; the University of California, San Diego; and GE Healthcare, a segmentation of General Electric, which provided the database for the study. Another latest study, reported Nov 10, 2010 at a assignation of the American Association for Cancer Research, also found that long-term use of statins did not inflation the hazard of cancer and might even decrease users' risks for lymphoma, melanoma and endometrial tumors.

New Study On Prevention Of Transfer Of HIV

New Study On Prevention Of Transfer Of HIV.
An antiviral antidepressant may assist conserve injection drug users from HIV infection, a rejuvenated study finds. The study of more than 2400 injection stimulant users recruited at 17 drug treatment clinics in Thailand found that constantly tablets of tenofovir reduced the risk of HIV infection by nearly 49 percent, compared to supine placebo pills anxiety. One crack said an intervention to help shield injection deaden users from HIV - the virus that causes AIDS - is much needed.

And "This is an prominent study that opens up an additional alternative 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 celebrated that "HIV infections at to manifest itself at high rates, with over 2,5 million worldwide and 50000 original infections in the US each year. This is teeth of widespread knowledge about HIV infection and the way it is spread, through unprotected going to bed and sharing needles for injecting drugs".

The participants included in the experimental 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 matching horde of patients taking a placebo, according to the consider published online June 12, 2013 in The Lancet. Further analyses of the results showed that the careful effect of tenofovir was highest to each those who most closely followed the drug's prescribed regimen.

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

High Doses Of Aspirin Reduce The Accuracy Of Colorectal Cancer Tests

High Doses Of Aspirin Reduce The Accuracy Of Colorectal Cancer Tests.
Stool tests that can determine blood from colorectal tumors are more spot on for patients on a low-dose aspirin regimen, which is known to grow intestinal bleeding, a green con suggests. While therapeutic aspirin use was once feared to skew the results of fecal shrouded blood tests, or FOBTs, German researchers found the analysis was significantly more sensitive for low-dose aspirin users than for non-users vimax dealer in abuja, nigeria?. Future studies confirming the results could prospect to recommendations to imagine small doses of aspirin before all such tests, gastroenterology experts said.

Aspirin's blood-thinning properties reminder some doctors to dictate low-dose regimens (usually 75 mg up to 325 mg) to those at jeopardize of cardiovascular events such as heart attacks. "We had expected that warmth was higher - that is, that more tumors were detected," said diva researcher Dr Hermann Brenner, a cancer statistics pro at the German Cancer Research Center in Heidelberg, Germany. "The surprising denouement was how strongly intuition was raised".

The study, conducted from 2005 to 2009, included 1979 patients with an commonplace age of 62; 233 were commonplace low-dose aspirin users, and 1746 never used it. Researchers analyzed the kind-heartedness and accuracy of two fecal shadowy blood tests in detecting advanced colorectal neoplasms, tumors that can either be toxic or benign. Participants were given stool collection instructions and devices, including bowel material for a later colonoscopy to authenticate results of the FOBTs. They self-reported aspirin and other medication use in standardized questionnaires.

Advanced tumors were found in the same piece of aspirin users and non-users, but the receptiveness of both stool tests was significantly higher among those taking low-dose aspirin - 70,8 percent versus 35,9 percent tender-heartedness on one examine and 58,3 percent versus 32 percent on the second. "The truth of stool tests in early detection of liberal bowel cancer is the detection of usually very teeny amounts of blood from the tumors. Use of low-dose aspirin facilitates this detection".

"If you're someone who's more timid offline, it makes sensation that you would be online too," said Dr Megan Moreno, of Seattle Children's Hospital and the University of Washington.

Moreno, who was not confusing in the research, studies issue people's use of social media. "There was a duration when people thought of the Internet as a place you go to be someone else. "But now it's become a district that's an height of your real life".

Indeed, kinfolk who use social-networking sites have handed over some of their self-presentation authority to other people, said con co-author Jeremy Birnholtz, director of the Social Media Lab at Northwestern University.

But the position to which that bothers you seems to depend on who you are and who your Facebook friends are. For the study, Birnholtz's body used flyers and online ads to recruit 165 Facebook users - mainly boyish adults - for an online survey. Of those respondents, 150 said they'd had an worrying or unskilful Facebook experience in the past six months.
