C. difficile lengthens hospital stays by 6 days

Canadian Medical Association Journal
A new study published in the CMAJ (Canadian Medical Association Journal) reports that hospital-acquired Clostridium difficile infection increases length of stay in hospital by an average of six days.
C. difficile is the most common cause of infectious diarrhea in hospital, and it is estimated that 10% of patients who become infected in hospital will die.
Researchers used The Ottawa Hospital Data Warehouse to analyze data on 136 877 admissions to The Ottawa Hospital between July 1, 2002 and March 31, 2009. A total of 1393 patients acquired C. difficile in hospital during this time, and these patients spent 34 days in hospital compared with 8 days for patients who did not have C. difficile. However, the researchers also found that patients who became infected with C. difficile tended to have more serious illnesses and would have been more likely to stay longer in hospital anyway. When the researchers controlled for the level of illness using a mathematical model, they found that hospital-acquired C. difficile increased the length of stay in hospital by six days.
"We believe our study provides the most accurate measure yet of the impact of hospital-acquired C. difficile on length of hospital stay," says lead author Dr. Alan Forster, a senior scientist at the Ottawa Hospital Research Institute and associate professor at the University of Ottawa. "C. difficile is a very serious problem for patients and for the health care system, however the good news is that tools such as The Ottawa Hospital Data Warehouse are providing us with more accurate information about C. difficile infection than we've ever had before, and this is helping us improve our infection-prevention efforts and also analyze their cost-effectiveness."
In a related commentary Dr. David Enoch, Peterborough and Stamford Hospitals, United Kingdom, and coauthor write that prevention and strict control measures are important for controlling the spread of the disease. "Adhering to basic evidence-based precautions can rapidly reduce the transmission of C. difficile and its associated mortality," they state. "Surveillance is essential to assess the efficacy of interventions."

Obama Faces the Loss of Pennsylvania in 2012 (ContributorNetwork)
COMMENTARY | Is President Barack Obama going to lose Pennsylvania next year and has he already written it off? That seems to be the premise of a recent Pittsburgh Tribune article examining the changing political dynamic in a nominally Democratic state.
While Obama won the state handily in 2008, the Republicans swept the state in 2010, winning a Senate seat, a lot of House seats, both chambers of the state legislature and the governorship. Disapproval of the president remains high among Pennsylvania voters at 59 percent.
Despite the fact Obama took Pennsylvania last time, his position there has always been soft, especially outside urban and suburban areas. During the 2008 primaries, Hillary Clinton took the state by nine points, according to the Pennsylvania Department of State, largely due to strength with blue collar Democrats.
Pennsylvanians have been dubious about Obama since the infamous bitter clinger speech the then-candidate made to a group of well-heeled campaign donors in San Francisco, as quoted by the Huffington Post. "And it's not surprising then they get bitter, they cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations." This sort of thing played well to rich folks in California but not so well to the people in Pennsylvania whose votes Obama wanted. Those remarks have never been forgotten by those very "bitter clingers" as many opponents of Obama now call themselves.
If Obama is contemplating the loss of Pennsylvania, along with nearby Indiana, he is looking at a challenging electoral map. He will have to win a number of southern states such as Virginia, North Carolina and Florida where his prospects appear to be even dimmer. The math simply does not add up.
If a sense of resignation, perhaps alternating with desperation, starts to sink in on the Reelect Obama campaign, those feelings are likely to spread among Democrats as a whole. There is nothing like a campaign that is sinking to bring out the most unattractive behavior in the people running them. Think about Jimmy Carter in 1980 or George H.W. Bush in 1992. It is a hard thing to lose the White House just four years after having won it. But it looks like Obama is now facing that bitter fate.

Water leaks from crippled Japanese nuclear plant (AP)
TOKYO ? Japan's crippled nuclear power plant leaked about 45 tons of highly radioactive water from a purification device over the weekend, its operator said, and some may have drained into the ocean.
The leak is a reminder of the difficulties facing Tokyo Electric Power Co. as it tries to meet its goal of bringing the tsunami-damaged Fukushima Dai-ichi nuclear power plant to a cold shutdown by year's end.
A pool of radioactive water was discovered midday Sunday around a decontamination device, TEPCO said in a statement on its website. After the equipment was turned off, the leak appeared to stop. Later, workers found a crack in a concrete barrier leaking the contaminated water into a gutter that leads to the ocean.
TEPCO estimated about 300 liters leaked out before the crack was blocked with sandbags.
Officials were checking whether any water had reached the nearby ocean.
The leakage of radioactive water from the Fukushima plant into the Pacific Ocean in the weeks after the March 11 accident caused widespread concern that seafood in the coastal waters would be contaminated.
The pooled water around the purification device was measured Sunday at 16,000 bequerels per liter of cesium-134, and 29,000 bequerels per liter of cesium-137, TEPCO said. That's 270 times and 322 times higher, respectively, than government safety limits, according to the Citizens' Nuclear Information Center in Tokyo.
Cesium-137 is dangerous because it can last for decades in the environment, releasing cancer-causing radiation. The half-life of cesium-134 is about two years, while the half-life of cesium-137 is about 30 years.
TEPCO is using the purification devices to decontaminate water that has been cooling the reactors. Three of the plant's reactor cores mostly melted down when the March 11 tsunami knocked out the plant's cooling system.

Lions' Suh crashes car in Portland; not injured (AP)
PORTLAND, Ore. ? Police in Oregon say Detroit Lions defensive tackle Ndamukong Suh crashed his car into a tree in downtown Portland, but was not injured.
Police say Suh was not impaired and was cooperative with officers following the accident at about 1:15 a.m. Saturday. Suh lost control of the 1970 Chevrolet Coupe he was driving, which then hit a curb, light pole, drinking fountain and tree. His vehicle was towed from the scene.
Suh had two passengers in the vehicle. They were not injured.
Suh is a graduate of Portland's Grant High School. He was the NFL's 2010 defensive rookie of the year. On Tuesday, the league suspended him for two games for stomping the arm of Packers guard Evan Dietrich-Smith.

Medvedev hails "equal competition" ahead of vote (AP)
MOSCOW ? Russian President Dmitry Medvedev says the nation's political parties enjoyed "free and equal competition" ahead of Sunday's parliamentary election, while voters complain of record violations of election law by the main pro-Kremlin party.
Medvedev on Friday hailed the upcoming election as "a high point of democracy."
Golos, a respected independent watchdog, has documented more than 4,500 election law violations mostly related to the dominant United Russia party.
Only Kremlin-approved parties are allowed to field candidates, and past elections have drawn strong accusations of vote rigging.
Independent pollster Levada Center said last week that United Russia will receive 53 per cent of the vote, down from 64 per cent in 2007.
