The Overall Rate Of Colon Cancer Has Fallen

The Overall Rate Of Colon Cancer Has Fallen.
Although the overall charge of colon cancer has fallen in just out decades, new research suggests that over the remain 20 years the disease has been increasing among young and early middle-aged American adults. At outgoing are colon cancer rates among men and women between the ages of 20 and 49, a assortment that generally isn't covered by public health guidelines. "This is real," said mug up co-author Jason Zell, an assistant professor in the departments of medicine and epidemiology at the University of California, Irvine. "Multiple explore organizations have shown that colon cancer is rising in those under 50, and our contemplation found the same, particularly among very young adults.

Which means that the epidemiology of this disease is changing, even if the through-and-through risk among young adults is still very low". Results of the study were published recently in the Journal of Adolescent and Young Adult Oncology. The muse about authors noted that more than 90 percent of those with colon cancer are 50 and older. Most Americans (those with no one's own flesh and blood history or heightened endanger profile) are advised to start screening at age 50.

Despite remaining the third most stereotyped cancer in the United States (and the number two cause of cancer deaths), a steady be produced in screening rates has appeared to be the main driving force behind a decades-long plummet in overall colon cancer rates, according to upbringing information in the study. An analysis of US National Cancer Institute data, published survive November in JAMA Surgery, indicated that, as a whole, colon cancer rates had fallen by inartistically 1 percent every year between 1975 and 2010.

But, that review also revealed that during the same time period, the rate among people aged 20 to 34 had in reality gone up by 2 percent annually, while those between 35 and 49 had seen a half-percent yearly uptick. To peruse that trend, the current study focused on data collected by the California Cancer Registry. This registry included dope on nearly 232000 colon cancer cases diagnosed between 1988 and 2009.

Sexting Can Be Dangerous For Teens

Sexting Can Be Dangerous For Teens.
Sexting is sending out sexually straightforward matter messages or photos by cellphone - is fairly common among teens, a fresh Belgian study finds in Dec 2013. And peer pressure, the hunt for romance and trust that the recipient will respond positively seem to be the key factors driving sexts. Adolescents apt to take a mostly benign view of the practice, the researchers found, dwelling little on the covert for negative fallout down the road. Warnings by parents or teachers against the practice appear to fall on deaf ears, with many teens unconcerned about parental monitoring of their phones or the unrealized for blackmail or future risk to their reputation.

And "During adolescence, progeny people explore their sexuality and identity, and form different kinds of friendships, including their to begin romantic relationships," said study lead author Michel Walrave, an allied professor in the department of communication studies at the University of Antwerp. "In this environment sexting can be used to express their interest in a potential partner," to maintain intimacy while dating, to attract in "truth-or-dare" flirting or to earn bragging rights among peers. The risk of unintended consequences is the problem.

So "As words and images sent can be obviously copied and transmitted, sexting messages can instantaneously spread to audiences that were not intended by the sender of the message. This can ruin the status of the depicted girl or boy, and lead to mockery or even bullying". The study appeared online in a fresh issue of the journal Behavior and Information Technology. The researchers conducted a written look into among nearly 500 Belgian girls and boys between the ages of 15 and 18 who were attending two rare secondary schools.

More than a quarter of the kids said they had sent out a sext during the two months supreme up to the poll. Girls were found to have a generally more negative view of sexting than boys. However, boys and girls already in purportedly trusting relationships seemed relatively disposed to embrace a behavior they perceived - rightly or wrongly - as delightful and desirable among their peers, the researchers found. The bottom row is that any intervention aimed at curbing teen sexting needs to accost the overriding social environment.

That is, one in which risky, explicit communications with a high potential for blowback are viewed without by friends and romantic partners. "Our study observed that especially the influence of peers is effective in predicting sexting behavior. Why? "Adolescents may be more focused on the short-term positive consequences of sexting, such as gaining heed of a desired other, than on the possible underestimated short-term and long-term negating consequences. "Raising awareness at school could alert young people to the risks of sharing sexually china content with a romantic partner, especially if the romance sours".

Americans Suffer High Blood Pressure

Americans Suffer High Blood Pressure.
High blood make is a preventable and treatable endanger factor for heart attack and stroke, but about one-quarter of adults don't discern they have it, according to a large new study. Among those who do know they have the condition, many are not likely to have it under control, said principal researcher Dr Uchechukwu Sampson, a cardiologist at Vanderbilt University Medical School in Nashville. "Despite all the movement we have made in having available treatment options, more than half of the living souls we studied still have uncontrolled high blood pressure.

The study is published in the January issue of the annal Circulation: Cardiovascular and Quality Outcomes. One in three US adults has high blood pressure, according to the US National Heart, Lung, and Blood Institute. Any reading over 140/90 millimeters of mercury is considered outrageous blood pressure. The bone up findings coincided with the Dec 18, 2013 issuing of rejuvenated guidelines for blood pressure management by experts from the institute's eighth Joint National Committee.

Among other changes, the untrained guidelines recommend that fewer men and women take blood pressure medicine. Older adults, under the new guidelines, wouldn't be treated until their blood intimidation topped 150/90, instead of 140/90. In Sampson's study, the researchers evaluated how workaday high blood pressure was in more than 69000 men and women. Overall, 57 percent self-reported that they had exalted blood pressure.

The New Role Of Stem Cells For Treatment Of Neoplastic Diseases

The New Role Of Stem Cells For Treatment Of Neoplastic Diseases.
For excruciating myeloid leukemia patients, overactive genes in their leukemic shoot cells (LSC) can ship into a more difficult struggle to overcome their disease and achieve prolonged remission, supplemental research reveals. "In many cancers, specific subpopulations of cells appear to be uniquely apt of initiating and maintaining tumors," the study authors explained in their report. The researchers identified 52 LSC genes that, when extremely active, appear to prompt worse outcomes among acute myeloid leukemia (AML) patients.

The finding is reported in the Dec 22/29 2010 emanate of the Journal of the American Medical Association. Between 2005 and 2007, over author Andrew J Gentles, of Stanford University in Palo Alto, California, and colleagues examined gene operation in a group of AML patients as well as healthy individuals. Separate details concerning AML tumors in four groups of patients (totaling more than 1000) was also analyzed.

In one of the serene groups, the investigators found that higher activity levels among 52 LSC genes meant a 78 percent jeopardize of death within a three-year period. This compared with a 57 percent peril of death in the same time frame for AML patients with lower gene activity surrounded by these specific "signature" genes. In another AML patient group, the research team observed that higher gene energy prompted an 81 percent risk for experiencing a disease hindrance over three years, compared with just a 48 percent risk among patients with low gene activity.

What's more, Gentles and his colleagues found that higher endeavour among these 52 LSC genes largely meant a poorer response to chemotherapy treatment and lower remission rates. The authors suggested that by "scoring" the vim levels of these 52 genes from low to high, clinicians might be able to better foretell how well AML patients will respond to therapy.
