British Ebola Survivor's Case Points to Delayed Complications from the Disease
A British nurse who survived Ebola has been hospitalized due to a delayed complication from her infection, health officials say.
Pauline Cafferkey, 39, contracted Ebola in Sierra Leone but was thought to have made a full recovery in January. As of Friday morning, she was in an isolation unit at the Royal Free Hospital in London, the Washington Post reported.
She has "an unusual late complication" of Ebola and is in serious condition, according to a statement from hospital. No further details were provided.
Other Ebola survivors have developed health problems believed to the result of lingering effects of the virus, raising concerns about the long-term effects of the disease on survivors, the Post reported.
A World Health Organization team went to Kenema, Sierra Leone a year ago to assess Ebola survivors who had a range of symptoms.
"Apart from visual problems which affect approximately 50 percent of Ebola survivors in Kenema, people complain of 'body aches' such as joint, muscle and chest pain. They also suffer headaches and extreme fatigue, making it difficult to take up their former lives -- especially if it involved manual work -- as farmers, labourers and housewives," according to the WHO's findings, the Post reported.
Vision problems were also common among Ebola survivors in Kenema.
While the Ebola virus may linger in some people, it's unlikely that survivors can transmit the virus to other people, according to infectious disease experts, the Post reported.
In Britain, health officials are seeking out people who may have had contact with Cafferkey as a precaution, but said the "risk to the general public remains low."
Organic Cheese Recalled by Whole Foods Market
Possible listeria contamination has led to the recall of all cut, wrapped and weighed Papillon organic Roquefort cheese sold at Whole Foods Market stores across the United States.
Listeria infection (listeriosis) can cause serious, life-threatening illness.
Whole Foods Market announced the recall after routine sampling conducted by the Food and Drug Administration detected listeria in a whole, uncut wheel of the cheese. The recalled cheese was cut and packaged in clear plastic wrap and sold with Whole Foods Market scale labels that begin with PLU 029536.
No illnesses or infections associated with the recalled cheese have been reported, according to Whole Foods Market. For more information, consumers can contact their local store or call 512-477-5566 ext. 20060 between 9 a.m. and 5 p.m. EST.
Organic Produce Reduces Pesticide Levels in Children: Study
Eating organic fruits and vegetables leads to a significant decline in the amount of pesticides and herbicides in children's bodies, a new study says.
It included 20 children in Oakland, Calif. and 20 children in the agricultural community of Salinas, about 100 miles south of Oakland. The youngsters ate conventional produce for four days, organic produce for seven days, and then conventional produce again for five days, The New York Times reported.
While the children were on the organic diet, their urine samples showed a nearly 50 percent decline in two of six of the most frequently detected pesticides, and a 25 percent drop in levels of a common herbicide.
The study was published in the October issue of the journal Environmental and Health Perspectives.
"There's evidence that diet is one route of exposure to pesticides, and you can reduce your exposure by choosing organic food," study lead author, Asa Bradman, associate director, Center for Environmental Research and Children's Health, University of California, Berkeley, told The Times.
"But I would never say that conventional fruits and vegetables are unsafe. They're all healthy," Bradman added.
Stem Cells Used to Grow Kidney and Intestine
Two groups of scientists made important advances in the quest to use stem cells to enable patients to grow their own organs for transplant.
An Australian team grew a primitive kidney and an American team created rudimentary intestines, NBC News reported.
The studies appear in the journals Nature and Regenerative Medicine, respectively.
The goal is to find a way to use a patient's stem cells to create lab-grown organs that are a perfect genetic match for that patient, NBC News reported.
