Daily multivitamin use reduced cancer occurrence in men

ScienceDaily (Oct. 17, 2012) ? Daily use of a common multivitamin reduced the risk for total cancer occurrence in a population of men followed for more than a decade, according to new data from the Physicians' Health Study II presented at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research, held here Oct. 16-19, 2012.

The study is being simultaneously published in the Journal of the American Medical Association.

"More than half of Americans take some kind of vitamin supplement, and the most commonly taken is a multivitamin," said John Michael Gaziano, M.D., chief of the Division of Aging at Brigham and Women's Hospital and a researcher at VA Boston. "No one has ever done a long-term trial to determine the potential health benefits or downsides of taking a multivitamin for a long period of time."

Gaziano and colleagues investigated the long-term effects of daily multivitamin use on certain site-specific cancers and total cancer occurrence and mortality. They used data from the Physicians' Health Study II, which included 14,641 male physicians aged 50 or older from the United States.

Researchers randomly assigned participants to a multivitamin or no multivitamin between 1997 and June 2011. During the median follow-up of 11.2 years, researchers recorded 2,669 cancer cases, including 1,373 prostate cancer cases and 210 colorectal cancer cases.

When examining outcomes at the study's end, the researchers found an 8 percent reduction in total cancer occurrence among participants assigned to multivitamin use.

"We also saw trends for some of the major site-specific cancers, though the numbers were small and not significant," Gaziano said. "There also seemed to be a greater effect in people with previous cancer."

Although prostate cancer was the most commonly occurring cancer in this population, there was no direct effect of multivitamin use on prostate cancer occurrence. However, when the researchers looked at the effect of a multivitamin on other site-specific cancers, they found about a 12 percent reduction in occurrence, according to Gaziano. Additionally, they saw a nonsignificant 12 percent reduction in cancer mortality.

"There are reasons to take a multivitamin even in our adult population, who are seemingly well nourished, as a way to get recommended daily amounts of vitamins and minerals," Gaziano said. "This study suggests, at least for men, that there might be benefits to taking multivitamins in terms of cancer as well."

Gaziano emphasized that the effects were modest and that multivitamin use should only be considered in addition to other habits, such as stopping smoking and increasing exercising, which literature has shown are effective in preventing cancer and other diseases.

Gaziano and colleagues plan to follow this population to determine if this effect strengthens over time. In addition, more studies on multivitamin use are needed in women.

Apple iPod touch (2012)


It's cheerful, colorful and versatile, and though it technically has competition, Apple's iPod touch still stands alone. While we still classify it as an MP3 player, the fully redesigned iPod touch is more like a smartphone without the phone, bringing more than 700,000 iOS apps along with iTunes, iBooks, and the rest of the Apple ecosystem to folks who don't want to pay full iPhone freight. This year's touch is a significant upgrade: It's faster, with a much better screen, a new camera, better headphones, and a new body design to die for.

This is the fifth iteration of the iPod touch, and it's the first model that's not getting a five-star rating. That's because it's a five-star product at a three-star price. Don't worry, it's still our Editors' Choice. There's nothing like it that's quite as good, but the entry-level price for this new model is very high. It's now $299 (32GB) or $399 (64GB), up from $199?and we called the $199 entry price 'hefty' two years ago. While that comes with double the storage (32GB, up from 16GB), it also makes the touch much more costly for all the people who want to use it for light gaming, Web browsing, and music. For those folks, last year's five-star touch is still available at $199. To find out what's new, read on.

Physical Design and Wi-Fi
The new iPod touch is the most elegant device I've ever handled?and yes, that includes the iPhone 5. It's shockingly thin, feather-light, and clad in an absolutely gorgeous wraparound aluminum body. You hardly notice it in your pocket.

Longer, slimmer, lighter, and better-looking than the 2011 iPod touch?, the new touch is available in blue, pink, red, yellow, gray, or black aluminum. At an amazing .24 inches thick and 3.10 ounces, it's almost two-dimensional and weightless. It's longer than previous touches at 4.86 inches high to accommodate a super-sharp 4-inch, 1,136-by-640 screen, but the same width as previous models at 2.31 inches wide. The new display is just like the one on the iPhone 5, and noticeably brighter than the previous iPod touch's screen. On the bottom you'll find an extremely tinny-sounding speaker, the 3.5mm headphone jack, and?Apple's new, compact Lightning connector, which, unfortunately, isn't natively compatible with any existing accessories without a $29 adapter. Apple says more Lightning docks and video-out cables are coming soon, but there's no exact timeframe.

In the box you get a pair of Apple's vastly improved EarPods?, and a "loop," a color-coordinated wrist strap that attaches to a pop-out button on the back panel of the player. The idea for the loop is to make the touch feel like a point-and-shoot digital camera, thanks to the 5-megapixel shooter that's been added to the back. The strap gets in the way when you're holding the touch in both hands to play games, though.

One of the major improvements here is enhanced wireless performance, which is especially important in a Wi-Fi-only device. Like the iPhone 5, the touch supports 802.11n Wi-Fi on the 5GHz band. In speed tests using the Ookla Speedtest.net app, we got double the Wi-Fi download speeds on 5GHz as opposed to 2.4GHz. That didn't have an effect on Web page load times, as the 2.4GHz network was fast enough that the touch's processor speed was what mattered there, but latency in wireless AirPlay gameplay was reduced.?

Performance and Apps
Built around the iPhone 4S's dual-core 800MHz A5 processor, the touch turns in solid performance. (The previous model had the iPhone 4's single-core A4 processor.) On the Geekbench system benchmark and GLBenchmark graphics benchmarks, the touch scored almost identically to the iPhone 4S running iOS 6.0. Scores on the Web-based Sunspider and Browsermark benchmarks were both a touch higher than the 4S, but the touch is in turn smoked by the much faster iPhone 5.

In real life, the performance differences between this touch, the previous iPod touch/iPhone 4, and the new iPhone 5 will build up with time. I couldn't find any app, even super-high-end games like Asphalt 7: Heat and Lili, that wouldn't run here, and those graphics-heavy apps will run much more smoothly than on the previous touch. Compared with the iPhone 5 (with its A6 processor, twice as fast as this one), I saw slightly smoother animations in games on the iPhone 5, much faster rendering of Google Earth images and faster Web pages loads. That's to be expected.

The touch runs Apple's?iOS 6, just like the iPhone 5. This OS update includes the aforementioned Wi-Fi improvements, wireless syncing, and AirPlay mirroring of your touch's display to an Apple TV, and also iMessage, Siri, Passbook, and the new Apple Maps. The older iPod touch will get most of these features if you update to iOS 6, but not Siri?for that you need a new device, but remember, you'll also need a working Wi-Fi connection.

The controversy over Apple's mapping app has just gone to show how spectacular Apple's array of third-party apps is. Within days of confirming issues with Apple Maps, we found 10 third-party alternatives in the App Store. That's the real strength of iOS, and that huge range of apps is why many people buy iPod touches. While Android is certainly catching up, you'll still find many games and other apps come out first and work best on iOS because Apple makes it easier for developers to make money from their work. (For more on that, read about One Android User's iPhone App Envy.)

The apps are getting huge, though, which is probably one reason Apple won't offer a new iPod touch smaller than 32GB. (There's no card slot for expansion here: Built-in storage is all you get.) It was easy to grab apps larger than 1GB each (Bard's Tale, Barefoot World Atlas, Asphalt 7: Heat, and Galaxy on Fire 2, to name a few), and my full load of 58 apps took up 10GB on our test device. Casual games are still much smaller, of course.

Battery life was a bit disappointing: I got 4 hours, 55 minutes of video playback with the screen at full brightness and Wi-Fi on, on an initial test. Since that's a bit less than the last generations' 5 hours, 32 minutes, and well short of the 8 hours Apple claims, I'll test it again after a few days' worth of charge and recharge cycles, and update this review.

Yoko Ono awards Lady Gaga peace prize in Iceland

REYKJAVIK (Reuters) - Pop star Lady Gaga was awarded a peace prize by Yoko Ono in a ceremony in Iceland on Tuesday.

Peace activist Ono said the LennonOno Grant for Peace, established in the name of her late husband, former Beatle John Lennon, rewarded Lady Gaga for combining stardom with activism and changing "the mental map" of the world.

"Lady Gaga is in a position of number one as a singer songwriter," Ono told Reuters Television. "And when you are number one you don't want to risk yourself. And she did."

Grammy-winning Lady Gaga, who shot to fame with her debut album "The Fame" in 2008, accepted the puzzle-shaped award in Reykjavik along with a monetary prize that she said she will give to the Elton John AIDS Foundation

Gaga said she would continue to "communicate compassionately to the world and its leaders," and dedicated the award to "youth empowerment around the world."

"I dare you to be compassionate in a cynical age," she added.

Last month, at an event in New York City, Yoko Ono awarded the prize to the members of Pussy Riot. Nadezhda Tolokonnikova, Maria Alyokhina and Yekaterina Samutsevich were sentenced to two years in jail in Russia for staging a "punk prayer" in Moscow's main cathedral.

Tolokonnikova's husband accepted the grant on behalf of the three women.

This year's winners of the prize also included peace activist Rachel Corrie, killed on the Gaza strip in 2003, "Confessions of an Economic Hit Man" author John Perkins and the late journalist Christopher Hitchens.
