Risky Behavior Comes From The Movies

Risky Behavior Comes From The Movies.
Violent moving picture characters are also favourite to drink alcohol, smoke cigarettes and engage in sexual behavior in films rated pertinent for children over 12, according to a new study. "Parents should be aware that youth who watch PG-13 movies will be exposed to characters whose savagery is linked to other more common behaviors, such as alcohol and sex, and that they should weigh whether they want their children exposed to that influence," said study lead author Amy Bleakley, a management research scientist at the University of Pennsylvania's Annenberg Public Policy Center. It's not apprehensible what this means for children who watch popular movies, however.

There's intense debate among experts over whether intensity on screen has any direct connection to what people do in real life. Even if there is a link, the new findings don't mention whether the violent characters are glamorized or portrayed as villains. And the study's resolution of violence was broad, encompassing 89 percent of popular G- and PG-rated movies. The study, which was published in the January circulation of the journal Pediatrics, sought to find out if violent characters also tied up in other risky behaviors in films viewed by teens.

Bleakley and her colleagues have published several studies lesson that kids who watch more fictional violence on screen become more violent themselves. Their research has come under devour from critics who argue it's difficult to gauge the impact of movies, TV and video games when so many other things power children. In September 2013, more than 200 people from academic institutions sent a affirmation to the American Psychological Association saying it wrongly relied on "inconsistent or indistinct evidence" in its attempts to connect violence in the media to real-life violence.

For the new study, the researchers analyzed almost 400 top-grossing movies from 1985 to 2010 with an sensitivity on violence and its connection to libidinous behavior, tobacco smoking and alcohol use. The movies in the sample weren't chosen based on their implore to children, so adult-oriented films little seen by kids might have been included. The researchers found that about 90 percent of the movies included at least one twinkling of an eye of violence involving a main character.

Cardiologists Recommend The Use Of Heart Rate Monitors

Cardiologists Recommend The Use Of Heart Rate Monitors.
A largely hand-me-down type of heart monitor may provide a simple way to predict a person's hazard for a common heart rhythm disorder called atrial fibrillation, according to a new research Dec 2013. Researchers found that people who have a greater number of heart contractions called early atrial contractions have a substantially higher risk for atrial fibrillation. These types of contractions can be detected by a 24-hour Holter monitor.

Premature atrial contractions are beforehand heartbeats that occur in the two uppermost chambers of the heart. A Holter monitor is a portable device that continuously monitors the electrical pursuit of a person's heart. The study included 1260 people, superannuated 65 and older, who had not been diagnosed with atrial fibrillation and underwent 24-hour Holter monitoring.

New Methods In The Study Of Breast Cancer

New Methods In The Study Of Breast Cancer.
An exploratory blood try could help show whether women with advanced breast cancer are responding to treatment, a preparation study suggests. The test detects abnormal DNA from tumor cells circulating in the blood. And the unique findings, reported in the March 14 issue of the New England Journal of Medicine, implication that it could outperform existing blood tests at gauging some women's answer to treatment for metastatic breast cancer. That's an advanced form of breast cancer, where tumors have bounds to other parts of the body - most often the bones, lungs, liver or brain.

There is no cure, but chemotherapy, hormonal group therapy or other treatments can slow disease progression and ease symptoms. The sooner doctors can recount whether the treatment is working, the better. That helps women avoid the school effects of an ineffective therapy, and may enable them to switch to a better one.

Right now, doctors monitor metastatic heart of hearts cancer with the help of imaging tests, such as CT scans. They may also use certain blood tests - including one that detects tumor cells floating in the bloodstream, and one that measures a tumor "marker" called CA 15-3.

But imaging does not discriminate the sound story, and it can expose women to significant doses of radiation. The blood tests also have limitations and are not routinely used. "Practically speaking, there's a whopping prerequisite for novel methods" of monitoring women, said Dr Yuan Yuan, an aid professor of medical oncology at City of Hope cancer center in Duarte, Calif.

For the untrained study, researchers at the University of Cambridge in England took blood samples from 30 women being treated for metastatic teat cancer and having standard imaging tests. They found that the tumor DNA check performed better than either the CA 15-3 or the tumor cell prove when it came to estimating the women's treatment response. Of 20 women the researchers were able to follow for more than 100 days, 19 showed cancer chain on their CT scans.

And 17 of them had shown rising tumor DNA levels. In contrast, only seven had a rising handful of tumor cells, while nine had an increase in CA 15-3 levels. For 10 of those 19 women, tumor DNA was on the go up an general of five months before CT scans showed their cancer was progressing. "The take-home message is that circulating tumor DNA is a better monitoring biomarker than the existing Food and Drug Administration-approved ones," said elder researcher Dr Carlos Caldas.

Smoking And Excess Weight Can Lead To A Cancer

Smoking And Excess Weight Can Lead To A Cancer.
Men with prostate cancer may raise their survival chances if they change animal fats and carbohydrates in their slim with healthy fats such as olive oils, nuts and avocados, new research suggests June 2013. Men who substituted 10 percent of their circadian calories from animal fats and carbs with such sturdy fats as olive oil, canola oil, nuts, seeds and avocados were 29 percent less qualified to die from spreading prostate cancer and 26 percent less disposed to to die from any other disease when compared to men who did not make this healthy swap, the study found. And a not any bit seems to go a long way.

Specifically, adding just one daily tablespoon of an oil-based salad dressing resulted in a 29 percent mark down risk of dying from prostate cancer and a 13 percent take down risk of dying from any other cause, the study contended. In the study, nearly 4600 men who had localized or non-spreading prostate cancer were followed for more than eight years, on average. During the study, 1064 men died.

Of these, 31 percent died from kindness disease, somewhat more than 21 percent died as a sequel of prostate cancer and slightly less than 21 percent died as a effect of another type of cancer. The findings appeared online June 10 in JAMA Internal Medicine. The go into can't say for sure that including healthy fats in the reduce was responsible for the survival edge seen among men.

Military Personnel And Their Partners Can Not Get Quality Treatment

Military Personnel And Their Partners Can Not Get Quality Treatment.
A medical doctor with practice caring for armed forces personnel says the US military's "Don't Ask, Don't Tell" regulation puts both service members and the prevalent public at risk by encouraging secrecy about sexual health issues. "Infections go undiagnosed. Service members and their partners go untreated," Dr Kenneth Katz, a doctor at San Diego State University and the University of California at San Diego, wrote in a commentary published Dec 1, 2010 in the New England Journal of Medicine.

And civilians "pay a price" because they have mating with employ members who feel nostalgia for out on programs aimed at preventing the spread of the HIV, the virus that causes AIDS, as well as other sexually transmitted diseases. The soldiery is currently pondering the end of the "Don't Ask, Don't Tell" policy, which does not brook gay service members to serve openly. No one knows how many gays are in the armed forces. However, one 2002 scan found that active-duty Navy sailors made up 9 percent of the patients who visited one vivid men's health clinic in San Diego.

CT Better At Detecting Lung Cancer Than X-Rays

CT Better At Detecting Lung Cancer Than X-Rays.
Routinely screening longtime smokers and historic massive smokers for lung cancer using CT scans can cut dow a fell the death rate by 20 percent compared to those screened by chest X-ray, according to a worst US government study. The National Lung Screening Trial included more than 53000 tenor and former heavy smokers aged 55 to 74 who were randomly chosen to be subjected to either a "low-dose helical CT" scan or a chest X-ray once a year for three years. Those results, which showed that those who got the CT scans were 20 percent less no doubt to die than those who received X-rays alone, were initially published in the logbook Radiology in November 2010.

The new study, published online July 29 in the New England Journal of Medicine, offers a fuller judgement of the facts from the trial, which was funded by the US National Cancer Institute. Detecting lung tumors earlier offers patients the possibility for earlier treatment. The data showed that over the course of three years, about 24 percent of the low-dose helical CT screens were positive, while just under 7 percent of the box X-rays came back positive, purport there was a suspicious lesion (tissue abnormality).

Helical CT, also called a "spiral" CT scan, provides a more unmixed picture of the chest than an X-ray. While an X-ray is a unattached image in which anatomical structures overlap one another, a spiral CT takes images of multiple layers of the lungs to bring into being a three-dimensional image. About 81 percent of the CT look patients needed follow-up imaging to determine if the suspicious lesion was cancer.

But only about 2,2 percent needed a biopsy of the lung tissue, while another 3,3 percent needed a broncoscopy, in which a tube is threaded down into the airway. "We're very ecstatic with that. We imagine that means that most of these positive examinations can be followed up with imaging, not an invasive procedure," said Dr Christine D Berg, scrutiny co-investigator and acting reserve director of the division of cancer prevention at the National Cancer Institute.

The vast majority of stubborn screens were "false positives" - 96,4 percent of the CT scans and 94,5 percent of X-rays. False pragmatic means the screening test spots an abnormality, but it turns out not to be cancerous. Instead, most of the abnormalities turned out to be lymph nodes or angry tissues, such as scarring from prior infections.

New Methods Of Diagnosis Of Stroke

New Methods Of Diagnosis Of Stroke.
The opener to correctly diagnosing when a instance of dizziness is just vertigo or a life-threatening stroke may be surprisingly simple: a pair of goggles that measures look movement at the bedside in as little as one minute, a new study contends. "This is the in front study demonstrating that we can accurately discriminate strokes and non-strokes using this device," said Dr David Newman-Toker, first author of a paper on the technique that is published in the April issue of the minute-book Stroke. Some 100000 strokes are misdiagnosed as something else each year in the United States, resulting in 20000 to 30000 deaths or demanding physical and speech impairments, the researchers said.

As with insensitivity attacks, the key to treating stroke and potentially saving a person's life is speed. Magnetic resonance imaging (MRI), the progress gold standard for assessing stroke, can take up to six hours to ended and costs $1200, said Newman-Toker, who is an associate professor of neurology and otolaryngology at Johns Hopkins Hospital in Baltimore. Sometimes grass roots don't even get as far as an MRI, and may be sent retreat with a first "mini stroke" that is followed by a devastating second stroke.

The new study findings come with some significant caveats, however. For one thing, the scrutiny was a small one, involving only 12 patients. "It is unworkable for a small study to prove 100 percent accuracy," said Dr Daniel Labovitz, the man of the Stern Stroke Center at Montefiore Medical Center in New York City, who was not complex with the study. About 4 percent of dizziness cases in the emergency area are caused by stroke.

The other caveat is that the device is not yet approved in the United States for diagnosing stroke. The US Food and Drug Administration only recently gave it licence for use in assessing balance. It has been at one's disposal in Europe for that purpose for about a year. The device - known as a video-oculography machine - is a modification of a "head impulse test," which is Euphemistic pre-owned regularly for people with chronic dizziness and other inner ear-balance disorders.

Preferred Brown Rice Instead Of White Rice Can Help Reduce The Risk Of Type 2 Diabetes

Preferred Brown Rice Instead Of White Rice Can Help Reduce The Risk Of Type 2 Diabetes.
Substituting brown rice or another total kernel for chalky rice can help reduce the risk of type 2 diabetes, unheard of research suggests. Five or more servings of white rice a week increased the endanger of type 2 diabetes by 17 percent, according to the study, which is published in the June 14 emanate of the Archives of Internal Medicine. But replacing white rice with brown rice could cut down the risk of developing type 2 diabetes by 16 percent, the study found.

So "This is an mighty message for public health. White rice is potentially harmful for the risk of kind 2 diabetes," said the study's lead author, Dr Qi Sun, an master of medicine at Harvard Medical School and a researcher at Brigham and Women's Hospital in Boston. "Over the at decade, rice consumption in the US has really increased a lot, but more than 70 percent of the rice consumed is hoary rice," said Sun "People should replace white rice with brown rice or in one piece grains".

The reason that brown rice may offer some protection, according to Sun, is that it still contains many of the nutrients and fiber that are stripped away in the output of white rice. During the refining and milling course of action necessary to make white rice, the rice loses a significant amount of its fiber and most of the vitamins and minerals, according to the study. "When you have just the deathly white rice, it's mostly protein and starch, and you're making freer carbohydrates that are unexacting to digest," said Dr Jacob Warman, chief of endocrinology at the Brooklyn Hospital Center in New York City. "With ivory rice, the digestive enzymes can more surely penetrate the rice grains and release the starch for digestion.

The Same Gene Is Associated With Obesity And Dementia

The Same Gene Is Associated With Obesity And Dementia.
A deviating of the obesity-related gene FTO may distend the risk of Alzheimer's disease and dementia, finds a immature Swedish study. Previous research has shown that the FTO gene affects body legion index (BMI), levels of leptin (a hormone involved in appetite and metabolism), and the chance for diabetes. All vascular risk factors that have also been linked with the risk of Alzheimer's disease.

This late study, conducted by the Karolinska Institute in Stockholm, included more than 1000 Swedish people, age-old 75 and older, who were followed for nine years. They all underwent genetic testing at the start of the study.

Dairy Products Contain Fatty Acids That Reduce The Risk Of Developing Type 2 Diabetes

Dairy Products Contain Fatty Acids That Reduce The Risk Of Developing Type 2 Diabetes.
New fact-finding suggests that whole-fat dairy products - on the whole shunned by robustness experts - contain a fatty acid that may mark down the risk of type 2 diabetes. The fatty acid is called trans-palmitoleic acid, according to the examination in the Dec 21, 2010 issue of the Annals of Internal Medicine, and multitude with the highest blood levels of this fatty acid reduce their odds of diabetes by 62 percent compared to those with the lowest blood levels of it. In addition, "people who had higher levels of this fatty acid had better cholesterol and triglyceride levels, humble insulin recalcitrance and lower levels of fervid markers," said study author Dr Dariush Mozaffarian, co-director of the program in cardiovascular epidemiology at Brigham and Women's Hospital and Harvard School of Public Health.

Circulating palmitoleic acid is found plainly in the kindly body. It's also found in small quantities in dairy foods. When it's found in sources foreign the human body, it's referred to as trans-palmitoleic acid. Whole withdraw has more trans-palmitoleic acid than 2 percent milk, and 2 percent milk has more of this fatty acid than does skate milk. "The amount of trans-palmitoleic acid is proportional to the amount of dairy fat".

Animal studies of the easily occurring palmitoleic acid have previously shown that it can protect against insulin defiance and diabetes, said Mozaffarian. In humans, research has suggested that greater dairy consumption is associated with a debase diabetes risk. However, the reason for this association hasn't been clear.

To assess whether this overlooked and rather rare fatty acid might contribute to dairy's apparent protective effect, the researchers reviewed details from over 3700 adults enrolled in the Cardiovascular Health Study. All of the participants were over 65 and lived in one of four states: California, Maryland, North Carolina and Pennsylvania.

Blood samples were analyzed for the attendance of trans-palmitoleic acid, as well as cholesterol, triglycerides, C-reactive protein and glucose levels. Participants also provided poop on their usual diets.
