Irish-born William Campbell and Japan’s Satoshi Omura won half of the prize for discovering avermectin, a derivative of which has been used to treat hundreds of millions of people with river blindness and lymphatic filariasis, or elephantiasis. China’s Tu Youyou was awarded the other half of the prize for discovering artemisinin, a drug that has slashed malaria deaths and has become the mainstay of fighting the mosquito-borne disease. She is China’s first Nobel laureate in medicine. Some 3.4 billion people, most of them living in poor countries, are at risk of contracting the three parasitic diseases. “These two discoveries have provided humankind with powerful new means to combat these debilitating diseases that affect hundreds of millions of people annually,” the Nobel Assembly at Sweden’s Karolinska Institute said. “The consequences in terms of improved human health and reduced suffering are immeasurable.”  Today, the medicine ivermectin, a derivative of avermectin made by Merck & Co, is used worldwide to fight roundworm parasites, while artemisinin-based drugs from firms including Novartis and Sanofi are the main weapons against malaria. Omura and Campbell made their breakthrough in fighting parasitic worms, or helminths, after studying compounds from soil bacteria. That led to the discovery of avermectin, which was then further modified into ivermectin. The treatment is so successful that river blindness and lymphatic filariasis are now on the verge of being eradicated. Omura, 80, said the real credit for the achievement should go to the ingenuity of the Streptomyces bacteria, whose naturally occurring chemicals were so effective at killing off parasites. “I really wonder if I deserve this,” he said after learning he had won the prize. “I have done all my work depending on microbes and learning from them, so I think the microbes might almost deserve it more than I do.”  Omura is professor emeritus at Kitasato University in Japan, while Campbell is research fellow emeritus at Drew University in Madison, New Jersey. “This was the work of a team of researchers so it is by no means my work, it’s our work,” said Campbell, 85, who learned of his prize in a pre-dawn phone call from Reuters that woke him at his home in North Andover, Massachusetts. “In the first decade, there were 70 authors that I co-authored papers with. That gives you some idea of the number of people involved,” he said. Tu, meanwhile, turned to a traditional Chinese herbal medicine in her hunt for a better malaria treatment, following the declining success of the older drugs chloroquine and quinine. She found that an extract from the plant Artemisia annua was sometimes effective but the results were inconsistent, so she went back to ancient literature, including a recipe from AD 350, in the search for clues. This eventually led to the isolation of artemisinin, a new class of anti-malaria drug, which was available in China before it reached the West. Tu, 84, has worked at the China Academy of Traditional Chinese Medicine since 1965. World Health Organization spokesman Gregory Hartl said the award of a Nobel prize for the discovery was a great tribute to the contribution of Chinese science in fighting malaria. “We now have drugs that kill these parasites very early in their life-cycle,” said Juleen Zierath, chair of the Nobel Committee. “They not only kill these parasites but they stop these infections from spreading.”     Death rates from malaria have plunged 60 percent in the past 15 years, although the disease still kills around half a million people a year, the vast majority of them babies and young children in the poorest parts of Africa. The 8 million Swedish crowns ($960,000) medicine prize is the first of the Nobel prizes awarded each year. Prizes for achievements in science, literature and peace were first awarded in 1901 in accordance with the will of dynamite inventor and businessman Alfred Nobel. Last year, the medicine prize went to three scientists who discovered the brain’s inner navigation system.

The story not only mentions the cost of a scan to individuals ($100 to $500), it also notes that about $50 million dollars was spent on this type of scanning nationwide in 2008. A longer story could have also reported on the costs of additional testing and treatments triggered by screening apparently healthy individuals. As mentioned above, the story notes that while some experts recommend CT screening for coronary artery calcium deposits in order to increase the number of people receiving treatment to reduce the likelihood of a heart, others are skeptical about the real value of this type of screening for apparently health people. The reporter points out that many heart attacks strike people who do not have very high cholesterol levels or other indicators of elevated risk, but also that “no study has linked the use of CT scans with better patient outcomes.”   The potential cancer risk caused by CT screening for signs of heart disease is the point of this story. Also, by highlighting uncertainty about the benefits of the screening and recapping debate over the Texas law mandating coverage of the scans, the story emphasizes the importance of considering potential harms when setting public policy on screening tests. A longer story could have considered other potential harms, including the side effects of treatments prescribed based on screening tests. The story does a good job of summarizing the results of this study of potential cancer risk from CT screening. In addition, it outlines the positions of experts and organizations on the broader body of evidence on the use of CT scans to identify people who may have plaque buildups in their heart arteries. It would have been better if the reporter stated that the estimate was based on several assumptions, that it wasn’t a definitive point estimate, but just the center of a range, and that it was higher than earlier estimates. Readers still got the point that there is a cancer risk which needs to be considered. The story notes that heart disease is the leading cause of death in the U.S., but it also points out doubts about whether screening with CT scans for calcium buildup in heart arteries can reduce the toll. The story includes experts and advocates that represent the key perspectives in debate about CT screening for calcium deposits in coronary arteries. However, it does not include information on possible conflicts of interest. Although this story points out that alternative screening techniques are available and it makes reference to cholesterol, it does not include any details about the alternatives. The story says that the CT scanners used for this test are “all over the city” and included an estimate that in 2008 about 200,000 people around the country were scanned for calcium buildups in their coronary arteries. not in question in this story The story includes quotes from independent experts and other information that was not in the news release about the journal article.
Warning sounded on heart scan law

The Arkansas Department of Health issued the public health directive in a Nov. 22 letter that stated students without at least two doses of measles, mumps and rubella vaccine either be vaccinated immediately or be barred from classrooms and school activities for at least 26 days. Brothers Shiloh Isaiah and Benjamin Andrew Bemis asked the Washington County Circuit to issue a temporary injunction, arguing “that the University of Arkansas failed to recognize and uphold our philosophical beliefs as enrolled students -- beliefs which include the choice to abstain from vaccinations.”   In a one-sentence order, Judge Doug Martin on Tuesday denied their request to be allowed to return to their classes without getting the vaccinations. Martin’s order didn’t explain the reason for the decision. Shiloh Bemis, 21, told the Arkansas Democrat-Gazette that he’s disappointed in the court’s order. “On a larger level, we are taking issue with the fact that we don’t think we’ve quite been given a choice that fully takes into account what we believe our rights to be,” the third-year architecture student from Fayetteville said. Benjamin Bemis didn’t respond to the Democrat-Gazette’s request for comment. State law requires vaccinations for students, but it also allows exemptions for medical, religious or philosophical reasons. But the state Health Department said even exempted students must heed the public health directive. “Even if they have an exemption, they still are supposed to be excluded from class and activities, since they are much more susceptible to getting the infection,” said Dr. Joel Tumlison, a physician specialist in the health department’s outbreak response team. “For any student, whether simply undervaccinated or with an exemption, if they change their mind and get the vaccine, they can then return to class/activities.” University spokesman Mark Rushing said the school will continue to follow the health department’s instructions. The university has had 26 mumps cases since September, according to health officials. As of last week, 168 students lacked the required vaccinations to attend classes, UA spokesman Zac Brown said.
