A spec bump in the middle of a product cycle? All the cool cats do it these days, even if they risk alienating customers who just bought what they thought was this year's flagship device. HTC has actually played this game for a while, first with the Sensation XE, which acted as a mid-term replacement for the original Sensation and now, with the One X+ which treads all over the One X's toes. However, with this latest handset, the manufacturer has some justification: the One X+ comes with 32GB or 64GB of internal storage, whereas the global One X maxed out at 32GB and the AT&T version was only 16GB. Since there's no microSD expansion on these phones, it's possible to argue that the One X+ is a sensible addition, which caters specifically to storage-hungry power users and audiophiles. (Note: We'll be reviewing the HSPA+ UK version of this handset here, and comparing it mainly to the HSPA+ One X. We'll test the US-destined LTE variant very soon.)
There are other improvements aside from the bigger storage option, of course. The NVIDIA Tegra 3 processor has had a speed bump to 1.7GHz -- perhaps in an effort to challenge the Galaxy S III's benchmarking might. There's a larger 2,100mAh battery to stay in step with that more power-hungry silicon; the front camera module has been replaced with a higher-res chip and better image processing; and, there's also some new audio circuitry to improve the speaker's sound quality. The One X+ also runs HTC's updated Sense 4+ skin, based on Jelly Bean, which will eventually arrive on older One-series phones as well. As for the rest of the spec sheet, all the good and not-so-good stuff from the One X has carried over -- the stunning 4.7-inch, 1,280 x 720 Super LCD2 display is still here, thank goodness, and so is the 8-megapixel f/2.0 rear camera. However, there's still only 1GB of RAM (LG and Samsung flagships boast double that). So, what's needed here is an upshot: if you haven't made the leap to a 2012 superphone just yet, how does the One X+ carry itself relative to its cheaper predecessor and the latest competition? Read on and we'll endeavor to find out.
Every week we?ll bring you all the inactives from the early games in one post, constantly updated with the latest information. So check back often to see the full list as it becomes available.

When astronauts return to Earth, their altitude isn't the only thing that drops?their blood pressure does too. This condition, known as orthostatic hypotension, occurs in up to half of those astronauts on short-term missions (two weeks or less) and in nearly all astronauts after long-term missions (four to six months). A new research reportpublished online in The FASEB Journal solves the biological mystery of how this happens by showing that low gravity compromises the ability of arteries and veins to constrict normally, inhibiting the proper flow of blood. Prevention and treatment strategies developed for astronauts may also hold promise for elderly populations on Earth who experience orthostatic hypotension more than any other age group.
"The idea of space exploration has been tantalizing the imagination of humans since our early existence. As a scientist, I have had the opportunity to learn that there are many medical challenges associated with travel in a weightless environment, such as orthostatic hypotension, bone loss and the recently recognized visual impairment that occurs in astronauts," said Michael D. Delp, Ph.D., a researcher involved in the work from the Department of Applied Physiology and Kinesiology, and the Center for Exercise Science at the University of Florida in Gainesville, Florida. "Although I have come to realize that it is unlikely I will ever get to fulfill my childhood dream of flying in space, I take great satisfaction with helping in the discovery of how microgravity alters the human body and how we can minimize these effects, so humans can safely explore the bounds of our universe."
To make this discovery, Delp and colleagues examined arteries and veins from mice housed at Kennedy Space Center in Florida with blood vessels from groups of mice flown on three of the last five space shuttle missions?STS-131, STS-133 and STS-135. Mice flown on the STS-131 and STS-135 missions were tested immediately after returning to Earth, whereas mice from STS-133 were tested one, five and seven days after landing. Not only did they find that these mice experienced the equivalent of orthostatic hypotension in humans, they also discovered that it takes as many as four days in normal gravity before the condition is reversed.
"There has been considerable interest in sending humans to the moon, asteroids, and Mars," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal, "but what we're finding is that extended space missions have their own inherent risks above and beyond the obvious. If we ever hope to visit distant worlds for extended periods of time?or colonize them permanently?we've got to figure out how to mitigate the effects that low and no gravity has on the body. This report brings us an important step closer to doing just that."

NASA spacecraft sees huge burp at Saturn after large stormPublic release date: 25-Oct-2012 [ | E-mail | Share ]

NASA's Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn. Data reveal record-setting disturbances in the planet's upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was more forceful than scientists previously thought.
Data from Cassini's composite infrared spectrometer (CIRS) instrument revealed the storm's powerful discharge sent the temperature in Saturn's stratosphere soaring 150 degrees Fahrenheit (83 kelvins) above normal. At the same time, researchers at NASA's Goddard Space Flight Center in Greenbelt, Md., detected a huge increase in the amount of ethylene gas, the origin of which is a mystery. Ethylene, an odorless, colorless gas, isn't typically observed on Saturn. On Earth, it is created by natural and man-made sources.
Goddard scientists describe the unprecedented belch of energy in a paper to be published in the Nov. 20 issue of the Astrophysical Journal.
"This temperature spike is so extreme it's almost unbelievable, especially in this part of Saturn's atmosphere, which typically is very stable," said Brigette Hesman, the study's lead author and a University of Maryland scientist who works at Goddard. "To get a temperature change of the same scale on Earth, you'd be going from the depths of winter in Fairbanks, Alaska, to the height of summer in the Mojave Desert."
First detected by Cassini in Saturn's northern hemisphere on Dec. 5, 2010, the storm grew so large that an equivalent storm on Earth would blanket most of North America from north to south and wrap around our planet many times. This type of giant disturbance on Saturn typically occurs every 30 Earth years, or once every Saturn year.
Not only was this the first storm of its kind to be studied by a spacecraft in orbit around the planet, but it was the first to be observed at thermal infrared wavelengths. Infrared data from CIRS allowed scientists to take the temperature of Saturn's atmosphere and to track phenomena that are invisible to the naked eye.
Temperature measurements by CIRS, first published in May 2011, revealed two unusual beacons of warmer-than-normal air shining brightly in the stratosphere. These indicated a massive release of energy into the atmosphere. After the visible signs of the storm started to fade, CIRS data revealed the two beacons had merged. The temperature of this combined air mass shot up to more than minus 64 degrees Fahrenheit (above 220 kelvins).
According to Hesman, the huge spike of ethylene generated at the same time peaked with 100 times more ethylene than scientists thought possible for Saturn. Goddard scientists confirmed the release of the gas using the Celeste spectrometer mounted on the McMath-Pierce Solar Telescope on Kitt Peak in Arizona.
The team still is exploring the origin of the ethylene, but has ruled out a large reservoir deep in the atmosphere.
"We've really never been able to see ethylene on Saturn before, so this was a complete surprise," said Goddard's Michael Flasar, the CIRS team lead.
A complementary paper led by Cassini team associate Leigh Fletcher of Oxford University, England, describes how the two stratospheric beacons merged to become the largest and hottest stratospheric vortex ever detected in our solar system. Initially, it was larger than Jupiter's Great Red Spot.
Their paper in the journal Icarus, which combines CIRS data with additional infrared images from other Earth-based telescopes, including NASA's Infrared Telescope Facility at Mauna Kea, Hawaii, also reports a powerful collar of clockwise winds -- encompassing a bizarre soup of gases -- around the vortex.
"These studies will give us new insight into some of the photochemical processes at work in the stratospheres of Saturn, other giants in our solar system, and beyond," said Scott Edgington, Cassini deputy project scientist at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency, and the Italian Space Agency. The mission is managed by JPL for NASA's Science Mission Directorate in Washington. Hesman's work was funded in part by NASA's Planetary Astronomy Program in Washington. The CIRS instrument and Celeste spectrometer were built at Goddard.

Victoria?s Secret gets a lot of flak within the lingerie industry.
Victoria secret shop , ?Icky Vicky? is one of their most common nicknames, and I don?t know a single lingerie blogger who?s given one of their bras a positive review. Their sizing chart makes no sense, and even though I wear a size they carry (a C cup), I don?t shop there anymore because the bras just don?t fit.
Victorias secret outlet , Add in their problematic marketing, child labor issues and, most recently, the hosiery knockoff scandal, and well?let?s just say the VS PR team really earns their paycheck.But that?s not what today?s article is about. For all of Victoria?s Secret?s problems, I think they fill a vital role within the lingerie industry and also within the lives of individual women.
Buy victoria secret ,I don?t know how it is in other countries, but in the U.S., Victoria?s Secret is the lingerie store.
Victoria secret outlet , And they are most women?s first exposure to pretty, lacy, and (dare I say it?) sexy lingerie. Most department stores (think Macy?s and J.C. Penney?s) sell really boring underwear.
Victoria secret online shop , Everything?s white, beige, or black. The only nylons are control top pantyhose.
Victoria secret sale , And every store carries the same 10 brands (which, coincidentally, are all owned by the same company?but more on that later). I remember being an early 20-something with a budding interest in pretty lingerie (this is pre-Gap Body, pre-Aerie, and pre-Lingerie Addict), and feeling like my choices were extremely limited. Except when I walked into a Victoria?s Secret.With over 1,000 stores in the U.S., Victoria?s Secret is everywhere. Every mall, shopping center, or downtown district has a VS. I grew up in a city with no lingerie boutiques (which is true for many women in America) and Victoria?s Secret was the only place to pick up anything remotely exciting. Not only did they have a larger lingerie selection than the department stores, the staff was consistently friendly, and, best of all, the prices were within even a student?s budget.Now I?m not waxing poetic about VS. They?re not one of my top 5 places for lingerie shopping. But when you?re brand new to the intimates and don?t know where else to go or even how to even start, Victoria?s Secret can be a gateway to the world of lingerie.To illustrate, when I was in college, lingerie boutiques felt very inaccessible to me. I didn?t know a good bra from a bad bra. I didn?t know why Bra X cost more than Bra Y. And I didn?t have a lot of money to spend on any of my clothes, including my underwear. Add in how the lingerie boutique experience can be a little uneven (especially, I think, if the sales staff has already decided you?re not a customer), and well, lingerie shopping can be extremely intimidating?especially for a newbie.But when I shopped at VS, I felt like it was okay for me to ?just look around,? and also felt like it was okay for me to explore all this new stuff I was interested in. I experimented with garter belts and thigh highs and cheeky panties and bustiers and bright colors and sheer lace and so much other stuff I couldn?t find elsewhere. Victoria?s Secret was literally my entry point to lingerie. I picked up my first ?sexy? lingerie set from them. I bought many of my first bras from them (and looking back, was introduced to some of my favorite styles this way). I bought a ton of cute panties from them. And before I knew anything about Kiss Me Deadly or Huit or Wacoal or Hopeless or any other of the brands I know and love now, I had a place to buy lingerie that made me feel pretty.Victoria?s Secret gets a lot of hate for their sizing practices, their over-emphasis on sexy, and the quality of their products (and rightly so), but I think they have another purpose in the industry at large, and that?s introducing women to lingerie. Victoria?s Secret helps make lingerie seem normal.For me, Victoria?s Secret was the first hint that there could be something better out there for me to wear beneath my clothes. And honestly, I?m not sure I?d have even started a lingerie blog without a VS nearby to keep my interest going during those early days.
? Today?s baby boomers love their computers, smartphones, and iPads, but a study shows that they?re falling short when it comes to safely using everyday technology.
For National Cyber Security Awareness month, AVG Technologies ? a company that sells computer security software ? did a survey to find out how boomers are doing in making sure their online lives are safe and secure.
Boomers, age 48 to 66, make up a quarter of the U.S. population. Eighty-one percent own desktop computers, 61 percent use laptops, and another 30 percent have smartphones. And, 20 percent use tablets to conduct online transactions.
While boomers are using today?s most advanced digital platforms, many aren?t aware of the resources available to protect their identities. Of the 1,300 baby boomers surveyed with home Internet access, AVG found the following:
65 percent don?t check online banking statements more than once a week.
Only about 40 percent use one low limit credit card for online purchases.
On mobile security, baby boomers also need to take action:
Almost 60 percent don?t use a cell phone password.
45 percent would have to manually re-enter data if their phone is lost or stolen.
Nearly 20 percent report at least one other person knows their passwords.
AVG Technologies suggest taking these online security steps to protect your financial well-being and data:
Use one credit card with a low spending limit for all online purchases. Monitor this account regularly and contact your bank or lending institution immediately about any inappropriate activity.
Change passwords regularly, use variations for each online account, and never share them with others. The Password Meter is a good and quick way to check your passwords.
Back up data on computers with external hard drives or a cloud-based solution. Back up mobile devices, too.
Protect personal information on mobile devices because hackers are targeting these tools. Programs are available for smartphones that add protection from malware and remotely wipe the device if it?s lost or stolen.
Be wary of phishing scams. Never click on links in e-mails from banks or other financial institutions. Go directly to their URL and enter login information from their homepage.

Romney promises to make the rich keep paying a constant percentage of all US income taxes. That's very different from asking them to pay a constant share of their earnings.
By Mark Trumbull,?Staff writer / October 22, 2012
In this Oct. 16 photo, Republican presidential candidate Mitt Romney speaks while President Obama listens during the second presidential debate at Hofstra University in Hempstead, N.Y.

A centerpiece of Mitt Romney's campaign for president, his plan for tax reform, revolves around a puzzling set of assertions. He says the rich will pay "the same" under his plan. He says the middle class will get "some relief." And yet he also says his tax reform won't add to federal deficits.
Click Here for your FREE 30 DAYS of The Christian Science Monitor Weekly Digital Edition
To lots of Americans this sounds, well, unusual. If one big chunk of taxpayers pays the same, and the other big chunk pays less, how can federal revenue stay the same?
This conundrum represents a large gray area in Romney's economic plan. Those listening to the Republican presidential candidate have rushed in to fill the void with various assumptions that may or may not prove to be correct.
Some voters reckon that Romney is implying, if anything, that he'd be willing to see a modest tax hike for upper income Americans, in order to cover the cost of modest middle-class tax relief. Others assume that, if elected, the former Massachusetts governor would be less than strict about the goal of not adding to federal deficits. Others argue that, contrary to the appearance of his rhetoric, Romney plans big tax cuts for the rich.
Some policy experts say Romney's own language offers hints that the last interpretation may be correct ? and that if Romney's plan were enacted, the top 5 percent of households appear likely to reap significant gains from the changes. This could occur, potentially, even if the reforms also delivered on Romney's stated goals of middle class tax relief and not adding to federal deficits.
Roberton Williams, a finance expert at the nonpartisan Tax Policy Center, says it may be vital to consider precisely what Romney has been saying: The candidate promises to make the rich keep paying a constant percentage of all US income taxes. That's very different, Mr. Williams says, from asking the rich to pay a constant share of their own earnings in income taxes.
If incomes for the rich continue to rise faster than for the middle class ? as has been the recent historical pattern ? then the rich could pay a constant share of federal income taxes even as the effective tax rate on their income steadily fell over time.
"In order to properly evaluate the 'fairness' of a tax system, you have to compare tax burdens to income levels, or ability to pay," says Diane Lim Rogers, chief economist at the Concord Coalition, a group that champions fiscal responsibility. By contrast, she says via email, a focus on the "share of taxes paid" can be tricky or misleading.
World's most advanced mirror for giant telescope completedPublic release date: 23-Oct-2012 [ | E-mail | Share ]

Scientists at the University of Arizona and in California have completed the first mirror for the Giant Magellan Telescope (GMT), the most challenging large astronomical mirror ever made
Scientists at the University of Arizona and in California have completed the most challenging large astronomical mirror ever made.
For the past several years, a group of optical scientists and engineers working at the UA Steward Observatory Mirror Laboratory underneath the UA's football stadium have been polishing an 8.4-meter (27 feet) diameter mirror with an unusual, highly asymmetric shape.
By the standards used by optical scientists, the "degree of difficulty" for this mirror is 10 times that of any previous large telescope mirror. The mirror surface matches the desired prescription to a precision of 19 nanometers so smooth that if it were the size of the continental U.S., the highest mountains would be little more than a half-inch high.
This mirror, and six more like it, will form the heart of the 25-meter Giant Magellan Telescope (GMT), providing more than 380 square meters, or 4,000 square feet, of light-collecting area. The Giant Magellan Telescope will lead a next generation of giant telescopes that will explore planets around other stars and the formation of stars, galaxies and black holes in the early universe.
Buell Jannuzi, director of the UA Steward Observatory and professor of astronomy, said, "Making this first GMT mirror required all the expertise and experience that the University has built up over 25 years of making telescope mirrors and a great deal of innovation to push beyond previous limits in optical fabrication and testing. In achieving this remarkable milestone, the team built and demonstrated all the equipment and techniques that will lead to efficient production of the remaining mirrors for the GMT."
The mirror was cast at the mirror lab from 20 tons of glass, melted in a rotating furnace until it flowed into a honeycomb mold. Once the glass had cooled and the mold material was removed, scientists at the lab used a series of fine abrasives to polish the mirror, checking its figure regularly using a number of precision optical tests.
The mirror has an unconventional shape because it is part of what ultimately will be a single 25-meter (82 feet) optical surface composed of seven circular segments, each 8.4 meters (27 feet) in diameter.
"We need to be certain the off-axis shape of this mirror, as well as the other six that will be made for GMT, is precisely right, to an accuracy of 1/20 of a wavelength of light," said Buddy Martin, polishing scientist at the Mirror Lab. "Only then will the seven large mirrors form a single, exquisitely sharp image when they all come together in the telescope in Chile. We have now demonstrated that we can fabricate the mirrors to the required accuracy for the telescope to work as designed."
The testing techniques, developed by Jim Burge, professor at the UA College of Optical Sciences, and his team, are a key part of the innovation enabling these giant off-axis mirrors. The second of seven mirrors for the GMT was cast at the mirror lab in January of this year; the third will be cast in August 2013.
The Giant Magellan Telescope will be located on a remote mountaintop in the Chilean Andes where the skies are clear and dark, far from any sources of light pollution. At the Carnegie Institution for Science's Las Campanas Observatory in northern Chile, earthmovers are completing the removal of 4 million cubic feet of rock to produce a flat platform for the telescope and its supporting buildings.
Wendy Freedman, chair of the GMT board, said: "The technical achievements at the UA's mirror lab and the dedication and commitment of our national and international partners will allow us to open a new window on the universe. An exciting future of discovery awaits us."
The telescope, slated to begin operations late in the decade, will allow astronomers and students across the U.S. and from around the world to address critical questions in cosmology, astrophysics and planetary science.
Matthew Colless, director of the Australian Astronomical Observatory, said, "The Giant Magellan Telescope has the potential to transform how we see the cosmos, and our place in it."

The mirror has an unconventional shape because it is part of what ultimately will be a single 25-meter (82 feet) optical surface composed of seven circular segments, each 8.4 meters (27 feet) in diameter.
"We need to be certain the off-axis shape of this mirror, as well as the other six that will be made for GMT, is precisely right, to an accuracy of 1/20 of a wavelength of light," said Buddy Martin, polishing scientist at the Mirror Lab. "Only then will the seven large mirrors form a single, exquisitely sharp image when they all come together in the telescope in Chile. We have now demonstrated that we can fabricate the mirrors to the required accuracy for the telescope to work as designed."
The testing techniques, developed by Jim Burge, professor at the UA College of Optical Sciences, and his team, are a key part of the innovation enabling these giant off-axis mirrors. The second of seven mirrors for the GMT was cast at the mirror lab in January of this year; the third will be cast in August 2013.
The Giant Magellan Telescope will be located on a remote mountaintop in the Chilean Andes where the skies are clear and dark, far from any sources of light pollution. At the Carnegie Institution for Science's Las Campanas Observatory in northern Chile, earthmovers are completing the removal of 4 million cubic feet of rock to produce a flat platform for the telescope and its supporting buildings.
Wendy Freedman, chair of the GMT board, said: "The technical achievements at the UA's mirror lab and the dedication and commitment of our national and international partners will allow us to open a new window on the universe. An exciting future of discovery awaits us."
The telescope, slated to begin operations late in the decade, will allow astronomers and students across the U.S. and from around the world to address critical questions in cosmology, astrophysics and planetary science.
Matthew Colless, director of the Australian Astronomical Observatory, said, "The Giant Magellan Telescope has the potential to transform how we see the cosmos, and our place in it."

The other day, Goggla sent me these photos of the levels monitoring the cracks of the long-vacant building at 255 E. Houston St. between Norfolk and Suffolk.
It has been a long time since we heard anything about the site's future. Last December, Crain's reported that the destabilized building, which once housed the Action for Progress school (they left in 2009), was on the market. Bids for the for the L-shaped parcel were due on Dec. 20. Real-estate types figured the building would house rentals rather than condos.
Earlier in December 2011, BoweryBoogie reported that the owner wanted a commercial zoning overlay for the property.
Per BB:
By gaining this amended zoning overlay, those involved could reap more cash from ground-floor commercial tenants like bars/restaurants rather than a community facility (if demolished under current zoning, would need to build a residential-compliant building).
However, there's still an active listing for the property, now being marketed this way: Community Facility/School/Medical Building for Net Lease. A few of the details on the four-story building, roughly 29,000 square feet plus the playground adjacent to the property on Suffolk Street.
? Whole building identity ? 11 large classrooms, each with bathrooms; numerous private offices; a commercial kitchen; ? Large meeting room; two small terraces; a large roofdeck; 4,600 sf playground. ? Expandable to 70,000 sf.
That expansion would likely take the building up to 12 floors. The property is in some disrepair (call it a fixer-upper), and the sidewalk bridge has long been providing shelter for some less-fortunate individuals. Here's a quick look around the building.
It's not clear if the deal includes 179 Suffolk St. next door, where there are plans on file for a five-floor (or taller!) residential development. Construction mishaps here prompted the evacuation of 255 E. Houston. Today, the stalled site is currently home to empty cans of cat food.
What?s affecting me, my clients and other small-business owners this week.
The Election: Binders Of Women
Small-business owners award a narrow victory to President Obama in the second debate, where it seemed the only good business is a small business. Of course, it didn?t take long for someone to songify the whole thing or for these reviews of binders for women to appear on Amazon. Matthew Yglesias urges the candidates to stop talking about small businesses and income tax rates: ?There are plenty of good ideas out there to spark small-business hiring, but to make them happen, politicians need to take a break from their obsession with arguing about the top marginal-income tax rate and look instead at payroll taxes and monetary policy.? J.D. Harrison writes a small-business guide to the upcoming election. A new survey from The Hartford finds that despite their views on the economy, small-business owners see themselves as largely successful. Oddly, gasoline prices seem to be dropping in important electoral states.
The Economy: Alarm Bells
Two Americans win Nobel prizes in economics. Business inventories increase, lifted by automobile stocks. Consumers are asking, ?What fiscal cliff?? as retail sales and industrial production rise. Gallup says economic confidence is at its highest since May. Residential building permits are strong and housing construction surges. Manufacturing in the Philadelphia area expands, but the New York region continues to contract. A forecast says global steel demand will slow next year. Inflation is up.

Cash Flow: A $41,500 Refrigerator
Here?s why prepaying expenses may not be your best option. Josh Patrick explains why you need to care about the cost of capital: ?Owners have to come to a better understanding of what their financial drivers are and figure out ways to produce the needed returns. Or, if that can?t be done, you can do what I did and decide the industry is never going to allow you to make the returns you need and find a way to leave.? This $41,500 refrigerator is the size of a small car. PayPal bolsters its credit offering for small businesses. The Boston Beer Company introduces a program to offer loans to small businesses (and a speed coaching event) in Los Angeles. Small businesses want better cash flow tools from banks.

The Week?s Bests
Jim Connolly says this is what every business owner needs to know about winning arguments: ?I often see small-business owners arguing with their customers, clients and contacts ? insisting they are right and the other person is wrong. They insist on winning the argument (imposing their opinion as the only valid one) rather than winning the client. That mindset is toxic to our business.?

Most adversities we face become nothing but a blip on the radar in time. So when dealing with business-related issues, consider them in a bigger context. How will this affect you in the long-term? Is your life?s work being destroyed, or are your goals just being pushed back by a day or two??

ScienceDaily (Oct. 22, 2012) ? Women under age 50 who have been diagnosed with endometrial cancer, and first, second and third degree relatives of patients with colorectal cancer may have an increased risk of developing colorectal cancer (CRC), according to two separate studies unveiled October 22 at the American College of Gastroenterology's (ACG) 77th Annual Scientific meeting in Las Vegas. Two other CRC-related studies presented at ACG 2012 investigated the impact of gender, race and obesity on the incidence of adenoma and advanced adenoma detection rates -- suggesting that overweight African American and Hispanic men may be at greater risk for precancerous polyps which if not detected early enough could lead to colorectal cancer.
Highlights of Colorectal Cancer Research from the ACG Annual Scientific Meeting
"Risk of Colorectal Cancer after Diagnosis of Endometrial Cancers: A Population-Based Study
"Women diagnosed with endometrial cancer under age 50 had a "marked increased risk" of being diagnosed with colorectal cancer in a historical cohort study by researchers at the University of Manitoba who linked several large longitudinal databases routinely collected in Manitoba, including the Manitoba Cancer Registry and some of Manitoba Health databases. The researchers followed 3,115 women diagnosed with endometrial cancer between 1987 and 2008 and 15,084 age-matched controls up to December 2009.
Women younger than 50 in the cohort at the time of diagnosis of endometrial cancer had an approximately four -fold increased risk of being subsequently diagnosed with colorectal cancer as compared to the age matched women in the general population. The risk was even higher (seven fold higher) for colorectal cancers occurring in the upper part of the colon (right colon). There was no increased risk for colorectal cancer among women diagnosed with endometrial cancer, when they were 50 years old or older.
Endometrial cancer is a cancer that starts in the inner lining of the womb (uterus) called the endometrium. In the U.S., endometrial cancer is the most common cancer found in women's reproductive organs. The chance of a woman having this cancer during her lifetime is about one in 38, according to the American Cancer Society.
"This study suggests there is an increased risk of colorectal cancer after a diagnosis of endometrial cancer among young women," said co-investigator Dr. Harminder Singh. He said, therefore these patients need close follow-up particularly for colorectal cancers occurring in the upper part (right-side) of the colon. "Colorectal cancer screening should start at a younger age in such women."
"Elevated Risk of Colorectal Cancer in Relatives of Patients with Colorectal Cancer: A Population-Based Study in Utah"
In the first population-based assessment of the risk of colorectal cancer in extended family members of patients with CRC, researchers from the Huntsman Cancer Institute in Salt Lake City, UT reported that first, second and third degree relatives of individuals with colorectal cancer had an increased risk of developing CRC themselves -- with the strength of the association based on the degree of kinship, according to lead investigator, Niloy Jewel Samadder, M.D.
The "degree of kinship" describes the proportion of genes shared by two blood relatives. A person's first-degree relative is a parent, sibling, or child. A first degree relative shares about half of their genes with the person. A second degree relative of a person is an uncle, aunt, nephew, niece, grandparent, grandchild or half- sibling. A second degree relative shares about one quarter of their genes with the person; while a third degree relative of a person is a first cousin, great-grandparent or great-grandchild. A third degree relative shares about one eighth of their genes with the person.
"This study has resolved many of the issues confounded in previous studies where reliance on patient recall regarding family history and lack of verification of reported colorectal cancer diagnoses have made it difficult to quantify the risk of CRC in the relatives of patients with colorectal cancer," said Dr. Samadder, noting that the "biggest strength" of the study is its design.
The retrospective case-control study included 126,936 Utah residents between 50 and 80 years old who underwent colonoscopy between February 15, 1995 and January 31, 2009 at Intermountain Healthcare of University of Utah Health System -- with 3,804 of these patients diagnosed with CRC -- and defined as the case population. For each case, 1 randomly selected age-and -sex-matched control was selected from the population who had CRC-free colonoscopy. Researchers confirmed family relationships through the Utah population database and CRC diagnosis through the Utah Cancer Registry. The results showed that first degree relatives of individuals with colorectal cancer had an 80 percent increased risk for CRC; second degree relatives had an increased risk of 30 percent and third degree relatives had an increased risk of 15 percent.
"Our data support the current CRC screening guidelines and raise the question of whether such screening should be extended to first-degree relatives of patients with CRC diagnosed at or above age 60," said Dr. Samadder, adding that the results, "further support a genetic basis of inheritance for CRC over shared environmental factors."
A key message from the study is that "the risk for colorectal cancer doesn't stop at our first-degree relatives," noted Dr. Samadder. He urged patients to be aware of their extended family histories and encouraged physicians to look beyond a patient's parents and grandparents when assessing colorectal cancer risk.
"Impact of BMI and Gender on Advanced Adenoma Detection Rates in Minority Populations" Body mass index (BMI) seems to have a linear association with advanced adenoma detection rates (ADR) in an African American and Hispanic male cohort, where a trend towards higher right-sided advanced adenomas is also seen in this study group, according to researchers from The Brooklyn Hospital Center.
Adenomas are a type of colon polyp that is considered a precursor for invasive colorectal cancer (CRC) which is the third most commonly diagnosed cancer and the second leading cause of cancer death in both men and women in the U.S., according to the American Cancer Society. It is estimated that there will be 143,460 new cases diagnosed in the United States in 2012 and 51,690 deaths due to this disease.
The study included 895 subjects with a mean age of 73 years and a higher proportion of females compared to males. African Americans made up 74 percent of the group and 26 percent were Hispanic. The study subjects were divided into five groups based on BMI, according to co-investigator Shashideep Singhal, M.D., who noted that males showed a progressive linear incremental trend in ADR with an increase in BMI. Total ADR was 14%, 12.9%, 13.9% and 16.3 % in Groups 1-4 with no statistical differences. Group 5 was excluded from analysis due to small sample size. The incidence of right-sided advanced adenomas was also higher with increasing BMI (60%, 60%, 64.3% and 71.4% in Groups 1-4 respectively). However, this trend was not seen in women in this cohort.
"The study shows that the higher the BMI the higher the adenoma detection rate and that African American and Hispanic men in this study group have the greatest risk for pre cancerous polyps which if not detected early could lead to colorectal cancer," said Dr. Singhal." He said that while these findings need to be confirmed with larger studies, they may have useful implications for designing preventive strategies in high-risk populations -- specifically identifying patients who are at high risk and increasing colonoscopy screening intervals in these patients who are at increased risk for CRC.
When detected early, polyps can be removed during a colonoscopy exam, preventing the development of colorectal cancer. This ability to prevent colorectal cancer through polyp removal is the cornerstone of the American College of Gastroenterology's 2009 screening guideline which recommends colonoscopy as a "preferred" colorectal cancer prevention strategy. The ACG also recommends African Americans undergo CRC screening at age 45 due to increased CRC risk factors. A tremendous body of evidence shows that clearing the colon of polyps, including small polyps, significantly reduces colorectal cancer mortality. When detected in its earliest and most treatable stage, the survival rates for colorectal cancer exceed 90 percent.
"Gender Specific Prevalence of Adenomas, Advanced Adenomas and Colorectal Cancer in Patients Undergoing Screening Colonoscopy"
Researchers from The University of Texas Medical Branch collected colonoscopy data retrospectively from a university-based hospital and included all average risk screening colonoscopies performed between 2006 and 2011 to determine and compare the prevalence and numbers needed to screen for adenomas, advanced adenomas and colorectal cancer in different age groups among men and women. Of the 2388 patients included in the study, 51 % were women.
Overall, men in the study group had a significantly higher prevalence of adenomas (32% vs. 23%) and advanced adenomas (8% vs. 5%) compared to women and the prevalence of CRC was higher in men, but did not reach statistical significance, according to co-investigator Dr. Praveen Guturu, MD.
When the data was broken down between different age groups, the prevalence of adenomas in the 50-59 year age group was significantly higher in men compared to women (29% vs. 19%). But there was no statistically significant difference in the prevalence of adenomas and advanced adenomas among men in the 60-69 age group and over 70 group, when compared to women. "Our study suggests that men might develop advanced colon polyps at an earlier age compared to women and this information will help us design appropriate screening and surveillance guidelines in future,'' said Dr Guturu.
