American Cancer Society: Fewer Americans Dying of Cancer

Cancer mortality rates have plummeted in the U.S., with advances in screening and treatment of the disease preventing over a million deaths from the deadly illness in the past two decades.

According to the American Cancer Society's (ACS) annual report on cancer statistics, death rates have fallen by 1.8 percent a year for men and 1.6 percent for women between 2004 and 2008. Cancer incidence rates declined by 0.6 percent per year in men and were stable in women during that period.

Between 1999 and 2008, cancer death rates dropped by more than 1 percent per year in men and women in every racial and ethnic group with the exception of American Indians/Alaska Natives, among whom rates have remained relatively stable.

As per the report released Wednesday, death rates drastically declined among black men, falling by 2.4 percent. Likewise, death rates for Hispanic men fell by 2.3 percent.

"Further progress can be accelerated by applying existing cancer control knowledge across all segments of the population, with an emphasis on those groups in the lowest socioeconomic bracket," authors of the ACS annual report said.

Other findings include a decline in death rates from lung, colon, breast and prostate cancers. For men the composite decrease in lung, prostate and colorectal cancer death rates account for 78 percent of the total decline, with lung cancer accounting for nearly 40 percent of the decrease. Among women, decrease in deaths from breast cancer account for 34 percent of the total decline, with a composite decline of 56 percent in breast and colorectal cancer deaths.

"This is really very exciting," said Ahmedin Jemal of the Atlanta-based American Cancer Society and co-author of the report. "Of course, the decrease is due to improvements in cancer prevention, early detection and treatment," she added in a in a statement on ABC News.

Despite the drop in mortality in all four major cancer sites, a new study published in the November issue of "Archives of Otolaryngology - Head & Neck Surgery" revealed that other cancer groups have been on the rise over the past decade. These include less common cancers of the pancreas, liver, thyroid, kidney as well as certain types of throat cancer associated with human papillomaviruses, as noted by Reuters.

One of the biggest reasons for the overall reduction in cancer deaths is the drop in smoking rates, a major carcinogenic factor especially for throat and lung cancer cases.

The ACS estimates there will be over 1.6 million new cases of invasive cancers and 577,190 cancer-related deaths for the year 2012.

Although the decline may not seem a significant figure, it does indicate that the healthcare system is moving in the right direction.

"It's good news," said Jemal on ABC News, "But there's more room for improvement, more room to accelerate progress in reducing cancer death rates."

Judge dismisses lawsuit in Italian kidnapping case (AP)

WASHINGTON ? A judge on Thursday threw out a former State Department official's lawsuit demanding diplomatic immunity against charges she helped kidnap a terrorism suspect in Italy but said the U.S. government's handling of the case sends a "potentially demoralizing" message to American civilians serving overseas.

U.S. District Judge Beryl Howell said the facts of the case brought by Sabrina De Sousa were troubling, but she's bound by the law to dismiss the lawsuit.

De Sousa was one of 26 U.S. officials tried in absentia in 2009 for the alleged kidnapping of Muslim cleric Osama Moustafa Hassan Nasr, also known as Abu Omar. It was the first trial in any country stemming from the CIA's "extraordinary rendition" program, which involved moving terrorist suspects from one country to another for interrogation outside the bounds of the criminal justice system.

Italian prosecutors said De Sousa, a naturalized U.S. citizen born in India, was a CIA officer working under diplomatic cover and was one of four main U.S. officials responsible for coordinating Nasr's capture from a Milan street on Feb. 17, 2003. Prosecutors said he was taken to his home country of Egypt, where he was held and allegedly tortured before eventually being released.

De Sousa said she was a foreign service officer at the U.S. consulate in Milan and denied that she worked for the CIA. She said that at the time of Nasr's capture she was vacationing at a ski resort nearly 130 miles away and was not involved.

But an Italian court convicted De Sousa and sentenced her to five years in prison. She has complained that the case makes it impossible for her to see her family in India because she risks extradition to Italy if she leaves the United States.

She resigned her job over the State Department's refusal to give her immunity and sued to try to force the department to provide it.

Governments can invoke immunity for their diplomats to protect them from prosecution in a host country. The United States neither waived nor invoked immunity for the officials in the Italian case. Twenty-three Americans and two Italians were convicted, but the judge at that time also acquitted three American diplomats, citing diplomatic immunity.

Government lawyers responded to De Sousa's suit by arguing that the courts have no authority to intervene in what is a foreign policy decision that must be left solely up to the executive branch. They also argued that the option of diplomatic immunity exists to benefit the nation applying it, not an individual government worker subjected to foreign legal action.

The judge agreed.

"The plaintiff seeks to challenge an essentially discretionary policy decision of the United States regarding whether to assert immunity for that employee in a foreign nation," Howell wrote in a 36-page opinion issued Thursday evening. "This type of claim presents a political question that this court cannot answer."

But, she wrote, "The facts underlying this case are troubling in many ways." She pointed out that De Sousa was convicted of a crime, not for any personal gain, but allegedly on behalf of the U.S. government and that her requests for assistance to fight the charges were denied. She said the risk of imprisonment if she travels outside the United States were a particular hardship because of her family members living abroad and the impact on her professional options.

"The message that this scenario sends to civilian government employees serving this country on tours of duty abroad is a potentially demoralizing one," Howell wrote.

Worm Infects 45,000 Facebook Users, Then Goes After Their Friends [Facebook]

Worm Infects 45,000 Facebook Users, Then Goes After Their FriendsMost of the time when you click on a Facebook link that a friend has posted, you get something nice. An amusing photo of a man embarrassed by his decisions. A video of Maru jumping into a box. But, if your friend has been infected with the Ramnit worm, you'll end up losing something.

Security company Seculert had been tracking the Ramnit worm when it discovered that the little beast jumped from committing financial fraud to stealing Facebook login credentials. Discovered in April of 2010, the worm is a multi-component malware that infects Windows executables, Office files, and HTML files. Once infected, it uses those files to steal authentication and transaction signing systems according to Microsoft.

Seculert states in a blog post:

We suspect that the attackers behind Ramnit are using the stolen credentials to log-in to victims' Facebook accounts and to transmit malicious links to their friends, thereby magnifying the malware's spread even further. In addition, cybercriminals are taking advantage of the fact that users tend to use the same password in various web-based services (Facebook, Gmail, Corporate SSL VPN, Outlook Web Access, etc.) to gain remote access to corporate networks.

So far the worm's Facebook invasion seems to be confined to mostly the UK and France. Still, it's always a good idea to switch up your passwords regularly. Not only on Facebook, but on any system that requires you to log in. [Seculert via Ars Technica]

'Synthetic' marijuana is problem for US military (AP)

SAN DIEGO ? U.S. troops are increasingly using an easy-to-get herbal mix called "Spice," which mimics a marijuana high and can bring on hallucinations that last for days.

The abuse of the drug has so alarmed military officials that they've launched an aggressive testing program that this year has led to the investigation of more than 1,100 suspected users, according to military figures.

So-called "synthetic" pot is readily available on the Internet and has become popular nationwide in recent years, but its use among troops and sailors has raised concerns among the Pentagon brass.

"You can just imagine the work that we do in a military environment," said Mark Ridley, deputy director of the Naval Criminal Investigative Service, adding, "you need to be in your right mind when you do a job. That's why the Navy has always taken a zero tolerance policy toward drugs."

Two years ago, only 29 Marines and sailors were investigated for Spice. This year, the number topped 700, the investigative service said. Those found guilty of using Spice are kicked out, although the Navy does not track the overall number of dismissals.

The Air Force has punished 497 airmen so far this year, compared to last year's 380, according to figures provided by the Pentagon. The Army does not track Spice investigations but says it has medically treated 119 soldiers for the synthetic drug in total.

Military officials emphasize those caught represent a tiny fraction of all service members and note none was in a leadership position or believed high while on duty.

Spice is made up of exotic plants from Asia like Blue Lotus and Bay Bean. Their leaves are coated with chemicals that mimic the effects of THC, the active ingredient in marijuana, but are five to 200 times more potent.

More than 40 states have banned some of its chemicals, prompting sellers to turn to the Internet, where it is marketed as incense or potpourri. In some states, Spice is sold at bars, smoke shops and convenience stores. The packets usually say the ingredients are not for human consumption but also tout them as "mood enhancing."

Service members preferred it because up until this year there was no way to detect it with urine tests. A test was developed after the Drug Enforcement Administration put a one-year emergency ban on five chemicals found in the drug.

Manufacturers are adapting to avoid detection, even on the new tests, and skirt new laws banning the main chemicals.

"It's a moving target," said Capt. J.A. "Cappy" Surette, spokesman for the Navy Bureau of Medicine and Surgery.

The military can calibrate its equipment to test for those five banned chemicals "but underground chemists can keep altering the properties and make up to more than 100 permutations," Surette said.

Complicating their efforts further, there are more than 200 other chemicals used in the drug. They remain legal and their effects on the mind and body remain largely unknown, Navy doctors say.

A Clemson University created many of the chemicals for research purposes in 1990s. They were never tested on humans.

Civilian deaths have been reported and emergency crews have responded to calls of "hyper-excited" people doing things like tearing off their clothes and running down the street naked.

Navy investigators compare the drug to angel dust because no two batches are the same. Some may just feel a euphoric buzz, but others have suffered delusions lasting up to a week.

While the problem has surfaced in all branches of the military, the Navy has been the most aggressive in drawing attention to the problem.

It produced a video based on cases to warn sailors of the drug's dangers and publicized busts of crew members on some of its most-storied ships, including the USS Carl Vinson, from which Osama bin Laden's was dropped into the sea.

Two of the largest busts this year involved sailors in the San Diego-based U.S. Third Fleet, which announced last month that it planned to dismiss 28 sailors assigned to the aircraft carrier USS Ronald Reagan.

A month earlier, 64 sailors, including 49 from the Vinson, were accused of being involved in a Spice ring.

Many of the cases were discovered after one person was caught with the drug, prompting broader investigations.

Lt. Commander Donald Hurst, a fourth-year psychiatry resident at San Diego's Naval Medical Center, said the hospital is believed to have seen more cases than any other health facility in the country.

Doctors saw users experiencing bad reactions once a month, but now see them weekly. Users suffer everything from vomiting, elevated blood pressure and seizures to extreme agitation, anxiety and delusions.

Hurst said the behavior in many cases he witnessed at first seemed akin to schizophrenia. Usually within minutes, however, the person became completely lucid. Sometimes, the person goes in and out of such episodes for days.

He recalled one especially bizarre case of a sailor who came in with his sobbing wife.

"He stood their holding a sandwich in front of him with no clue as to what to do," he said. "He opened it up, looked at it, touched it. I took it and folded it over and then he took a bite out it. But then we had to tell him, `you have to chew.'"

An hour later when Hurst went back to evaluate him, he was completely normal and worried about being in trouble.

"That's something you don't see with acute schizophrenic patients," he said. "Then we found out based on the numbers of people coming in like this, that OK there's a new drug out there."

Hurst decided to study 10 cases. Some also had smoked marijuana or drank alcohol, while others only smoked Spice.

Of the 10, nine had lost a sense of reality. Seven babbled incoherently. The symptoms for seven of them lasted four to eight days. Three are believed to now be schizophrenic. Hurst believed the drug may have triggered the symptoms in people with that genetic disposition. His findings were published in the American Journal of Psychiatry in October.

He said there are countless questions that still need answering, including the drug's effects on people with Post Traumatic Stress Disorder or traumatic brain injuries.

What the research has confirmed, he said, is: "These are not drugs to mess with."

New clues as to why some older people may be losing their memory

ScienceDaily (Dec. 29, 2011) ? New research links 'silent strokes,' or small spots of dead brain cells, found in about one out of four older adults to memory loss in the elderly. The study is published in the January 3, 2012, print issue of Neurology?, the medical journal of the American Academy of Neurology.

"The new aspect of this study of memory loss in the elderly is that it examines silent strokes and hippocampal shrinkage simultaneously," said study author Adam M. Brickman, PhD, of the Taub Institute for Research on Alzheimer's Disease and the Aging Brain at Columbia University Medical Center in New York.

For the study, a group of 658 people ages 65 and older and free of dementia were given MRI brain scans. Participants also underwent tests that measured their memory, language, speed at processing information and visual perception. A total of 174 of the participants had silent strokes.

The study found people with silent strokes scored somewhat worse on memory tests than those without silent strokes. This was true whether or not people had a small hippocampus, which is the memory center of the brain.

"Given that conditions like Alzheimer's disease are defined mainly by memory problems, our results may lead to further insight into what causes symptoms and the development of new interventions for prevention. Since silent strokes and the volume of the hippocampus appeared to be associated with memory loss separately in our study, our results also support stroke prevention as a means for staving off memory problems," said Brickman.

The study was supported by the National Institutes of Health.
