Researchers Warn About The Harmful Influence Of TV

Researchers Warn About The Harmful Influence Of TV.
A imaginative scrutiny suggests that immersing yourself in news of a shocking and tragic event may not be good for your affective health. People who watched, read and listened to the most coverage of the Boston Marathon bombings - six or more hours quotidian - reported the most acute stress levels over the following weeks. Their symptoms were worse than kinsmen who had been directly exposed to the bombings, either by being there or knowing someone who was there.

Those exposed to the media coverage typically reported around 10 more symptoms - such as re-experiencing the blow and compassion stressed out thinking about it - after the results were adjusted to account for other factors. The study authors phrase the findings should raise more concern about the effects of graphic news coverage. The scrutinize comes with caveats. It's not clear if watching so much coverage directly caused the stress, or if those who were most troubled share something in common that makes them more vulnerable.

Nor is it known whether the stress affected people's true health. Still, the findings offer insight into the triggers for stress and its potential to linger, said inquiry author E Alison Holman, an associate professor of nursing science at the University of California, Irvine. "If proletariat are more stressed out, that has an impact on every part of our life. But not everybody under the sun has those kinds of reactions.

It's important to understand that variation". Holman, who studies how people become stressed, has worked on preceding research that linked acute stress after the 9/11 attacks to later resolution disease in people who hadn't shown signs of it before. Her research has also linked watching the 9/11 attacks palpable to a higher rate of later physical problems. In the new study, researchers old an Internet survey to ask questions of 846 Boston residents, 941 New York City residents and 2888 society from the rest of the country.

Still Some Differences Between The Behavior Of Men And Women

Still Some Differences Between The Behavior Of Men And Women.
While not every broad is intuitive or every guy handy with tools, neurological scans of progeny males and females suggest that - on average - their brains really do develop differently. The digging comes with a caveat: It doesn't connect the brain-scan findings to the actual ways that these participants conduct in real life. And it only looks at overall differences among males and females. Still, the findings "confirm our hunch that men are predisposed for rapid action, and women are predisposed to cogitate about how things feel," said Paul Zak, who's familiar with the study findings.

And "This remarkably helps us understand why men and women are different," added Zak, founding chief honcho of the Center for Neuroeconomics Studies at Claremont Graduate University in California. Researchers Ragini Verma, an affiliate professor of radiology at the University of Pennsylvania, and colleagues used scans to study the brains of 428 males and 521 females aged 8 to 22.

The goal was to better realize the connectivity in the brain and determine if certain types of wiring are in good shape or like a lane "that could be broken or has a bad rough patch that needs to be covered over". The swat found that, on average, the brains of men seem to be better equipped to comprehend what people perceive and how they react to it. Females, on average, appear to be better able to stick the parts of their brains that handle analysis and intuition.

Alzheimer's Disease Against A Cancer

Alzheimer's Disease Against A Cancer.
Although a chew over in 2012 suggested a cancer deaden could reverse the thinking and memory problems associated with Alzheimer's disease, three groups of researchers now conjecture they have been unable to duplicate those findings. The teams said their experimentation could have serious implications for patient safety since the drug involved in the study, bexarotene (Targretin), has unsmiling side effects, such as major blood-lipid abnormalities, pancreatitis, headaches, fatigue, weight gain, depression, nausea, vomiting, constipation and rash. "Anecdotally, we have all heard that physicians are treating their Alzheimer's patients with bexarotene, a cancer pharmaceutical with punitive side effects," said study co-author Robert Vassar, a professor of chamber and molecular biology at Northwestern University Feinberg School of Medicine, in Chicago.

This way should be ended immediately, given the failure of three independent research groups to replicate the plaque-lowering clobber of bexarotene. The US Food and Drug Administration approved bexarotene in 1999 to manage refractory cutaneous T-cell lymphoma. Once approved, however, the narcotize also was available by prescription for "off-label" uses.

The 2012 study suggested that bexarotene was able to speedily reverse the build-up of beta amyloid plaques in the brains of mice. The authors of the beginning study concluded that treatment with the drug might reverse the cognitive and memory problems associated with the maturing of Alzheimer's. Sangram Sisodia, a professor of neurosciences at the University of Chicago and a study co-author of the modern development research, admitted being skeptical about the initial findings.

New Way To Fight Mosquitoes

New Way To Fight Mosquitoes.
Researchers have scholastic more about how mosquitoes spot skin odor, and they say their findings could lead to better repellants and traps. Mosquitoes are attracted to our coat odor and to the carbon dioxide we exhale. Previous research found that mosquitoes have special neurons that sanction them to detect carbon dioxide. Until now, however, scientists had not pinpointed the neurons that mosquitoes use to catch skin odor.

The new study found that the neurons used to detect carbon dioxide are also worn to identify skin odor. This means it should be easier to find ways to block mosquitoes' faculty to zero in on people, according to the study's authors. The findings appeared in the Dec 5, 2013 culmination of the journal Cell.

Most Americans And Canadians With HIV Diagnosed Too Late

Most Americans And Canadians With HIV Diagnosed Too Late.
Americans and Canadians infected with HIV are not getting diagnosed without delay enough after exposure, resulting in a potentially toxic set back in lifesaving treatment, a new large study suggests. The observation stems from an inquiry involving nearly 45000 HIV-positive patients in both countries, which focused on a key yardstick for untouched system strength - CD4 cell counts - at the time each patient beginning began treatment. CD4 counts measure the number of "helper" T-cells that are HIV's preferred target.

Reviewing the participants' medical records between 1997 and 2007, the pair found that throughout the 10-year study period, the run-of-the-mill CD4 count at the time of first treatment was below the recommended level that scientists have elongate identified as the ideal starting point for medical care. "The public health implications of our findings are clear," turn over author Dr Richard Moore, from the Johns Hopkins University School of Medicine in Baltimore, said in a message release. "Delayed diagnosis reduces survival, and individuals enter into HIV supervision with lower CD4 counts than the guidelines for initiating antiretroviral therapy". A dilly-dallying in getting treatment not only increases the chance that the disease will progress, but boosts the risk of transmission.

Women Are Happy To Be A Donor Egg

Women Are Happy To Be A Donor Egg.
Most women who give out as egg donors take on a positive take on their experience a year later, redesigned research indicates. Researchers polled 75 egg donors at the time of egg retrieval and one year later, and found that the women remained happy, honourable and carefree about their experience. "Up until now we've known that donors are by and strapping very satisfied by their experience when it takes place," said read lead author Andrea M Braverman, director of complementary and alternative medicine at Reproductive Medicine Associates of New Jersey in Morristown. "And now we usher that for the vast majority the doctrinaire experience persists".

Braverman and colleagues from the Robert Wood Johnson Medical School in Piscataway, NJ, were scheduled to largesse their survey findings Wednesday in Denver at a meeting of the American Society for Reproductive Medicine. A year after donation, the women said they rarely worried about either the health or fervent well-being of the children they helped to spawn. They said they only think about the donation occasionally and on rare occasions discuss it.

The donors also reported that financial compensation was not the number-one motive for facilitating another woman's pregnancy. Rather, a after to help others achieve their dreams was pegged as the driving force, followed by paper money and feeling good.

Women who said the donation process made them feel worthwhile tended to be unagreed to the notion of meeting their offspring when they reach adulthood. And most donors were receptive to the design of meeting the egg recipients and participating in a donor registry.

Premature Babies Are More Prone To Stress And Disease

Premature Babies Are More Prone To Stress And Disease.
New investigate suggests that the adverse clobber of pre-term birth can extend well into adulthood. The modern development findings, from a University of Rhode Island study that has followed more than 200 premature infants for 21 years, revealed that preemies become up to be less healthy, struggle more socially and face a greater jeopardize of heart problems compared to those born full-term. One reason for this, explained lessons author Mary C Sullivan, professor of nursing at the University of Rhode Island and adjunct professor of pediatrics at the Alpert Medical School at Brown University, is that darned low extraction weight, repeated blood draws, surgery and breathing issues can affect stress levels surrounded by pre-term infants.

She pointed out these stressors produce higher levels of the hormone cortisol, which is affected in the regulation of metabolism, immune response and vascular tone. Among Sullivan's findings that.

The less a preemie weighs at birth, the greater the risk. Sullivan found preemies born at uncommonly down birth weight had the poorest pulmonary outcomes and higher resting blood pressure. Premature infants with medical and neurological problems had up to a 32 percent greater hazard for alert and chronic health conditions vs normal-weight newborns. Pre-term infants with no medical conditions, specifically boys, struggled more academically. Sullivan found that preemies tended to have more learning disabilities, agitation with math and need more school services than kids who were full-term babies. Some children born too soon are less coordinated. This may be related to brain development and effects of neonatal intensive care, the researchers said. Premature infants also tended to have fewer friends as they matured, the band found.

A Diet Rich In Omega-3, Protects The Elderly From Serious Eye Diseases

A Diet Rich In Omega-3, Protects The Elderly From Serious Eye Diseases.
Eating a subsistence money in omega-3 fatty acids appears to keep seniors against the onset of a serious eye disease known as age-related macular degeneration (AMD), a supplemental analysis indicates. "Our study corroborates earlier findings that eating omega-3-rich fish and shellfish may tend against advanced AMD," study lead author Sheila K West, of the Wilmer Eye Institute at Johns Hopkins School of Medicine in Baltimore, said in a info issue from the American Academy of Ophthalmology. "While participants in all groups, including controls, averaged at least one serving of fish or shellfish per week, those who had advanced AMD were significantly less favoured to throw away high omega-3 fish and seafood," she added.

The observations are published in the December spring of Ophthalmology. West and her colleagues based their findings on a fresh analysis of a one-year dietary assess conducted in the early 1990s. The poll involved nearly 2,400 seniors between the ages of 65 and 84 living in Maryland's Eastern Shore region, where fish and shellfish are eaten routinely. After their grub intake was assessed, participants underwent ogle exams.

About 450 had AMD, including 68 who had an advanced put on of the disease, which can lead to severe vision enfeeblement or blindness. In the United States, AMD is the major cause of blindness in whites, according to background knowledge in the news release. Prior evidence suggested that dietary zinc is similarly protective against AMD, so the researchers looked to learn if zinc consumption from a diet of oysters and crabs reduced jeopardize of AMD, but no such association was seen.

The Need For Annual Breast MRI In Addition To Annual Mammography

The Need For Annual Breast MRI In Addition To Annual Mammography.
Women who have had boob cancer should think annual screening with breast MRI in extension to an annual mammogram, new research indicates. Currently, the American Cancer Society recommends annual teat MRI plus mammography for women at very high risk for titty cancer, such as those with a known genetic mutation known as BRCA or those with a very strong family history. But it takes no post on MRI imaging for women who have had breast cancer, saying there is not enough evidence to urge one way or the other.

Studying the effectiveness of MRI screening on all three groups of women, Dr Wendy DeMartini, an aid professor of radiology at the University of Washington Medical School, said MRI imaging found proportionally more cancers in women who had been treated for chest cancer than in the women considered at very capital risk. "Women in the personal history group who had MRI were also less likely to be recalled for additional testing, and less indubitably to have a biopsy for a false positive finding," she said.

DeMartini was scheduled to present the findings Sunday at the annual caucus of the Radiological Society of North America in Chicago. For the study, her side reviewed initial breast MRI exams of 1026 women, conducted from January 2004 to June 2009. Of these, 327 had a genetic or genre history; 646 had a individual history of breast cancer that had been treated.
