Input: Consider Input: Paragraph: Such a test could initially be used to select patients for clinical trials of experimental treatments being developed to try to halt progression of Alzheimer's, the researchers said, and may one day move into routine use in doctors' clinics. "Alzheimer's begins to affect the brain many years before patients are diagnosed (and) many of our drug trials fail because by the time patients are given the drugs the brain has already been too severely affected," said Simon Lovestone of Oxford University, who led this work from King's College London. "A simple blood test could help us identify patients at a much earlier stage to take part in new trials and hopefully develop treatments," he said. Alzheimer's is the most common form of dementia, a brain-wasting disease which in 2010 was estimated to be costing the world $604 billion a year. The fatal disease affects 44 million people worldwide, with the number set to triple by 2050, the campaign group Alzheimer's Disease International says. Several big pharma firms including Roche, Eli Lilly, Merck & Co and Johnson & Johnson, are pursuing various approaches to get to the root cause of Alzheimer's and try to find treatments to halt its progression. Yet over the past 15 years, more than 100 experimental Alzheimer's drugs have failed in trial. Lovestone and other experts believe this may be because drug trials are conducted too late, in patients whose condition has already gone too far. A predictive test for use before people develop symptoms would help researchers select the right people for drug trials, and help show whether the experimental drugs are working. Previous studies have found that PET brain scans and tests of lumbar fluid can be used to predict the onset of dementia from people with a less severe condition known as mild cognitive impairment (MCI), but these tests are expensive and invasive, so scientists are keen to develop a cheaper, simpler blood test. MCI includes problems with day-to-day memory, language and attention. It can be an early sign of dementia, or a symptom of stress or anxiety. Around 10 percent of people diagnosed with MCI develop dementia within a year. Apart from regular assessments to measure memory decline, there is currently no accurate way of predicting who will or won't develop dementia. For this study, published in the journal Alzheimer's & Dementia, Lovestone's team used blood samples from 1,148 people - 476 with Alzheimer's, 220 with mild cognitive impairment and 452 elderly controls without dementia. They were analyzed for 26 proteins previously found to be linked with Alzheimer's. The team found 16 of these 26 proteins to be strongly associated with brain shrinkage in either MCI or Alzheimer's and then ran a second series of tests to see which of these could predict which patients would progress from MCI to Alzheimer's. With this second series, they found a combination of 10 proteins capable of predicting with 87 percent accuracy whether people with MCI would develop Alzheimer's disease within a year. Experts in the field welcomed the results but said they should be replicated in larger studies before an Alzheimer's blood test could be rolled out for use in doctors' clinics. "The results reported today are interesting, but as the authors point out there is still a very large amount of work remaining until a usable blood test for Alzheimer's disease becomes available," said Adrian Pini of the MRC Center for Developmental Neurobiology at King's College London. James Pickett, head of research at the Alzheimer's Society, said the research "does not mean that a blood test for dementia is just around the corner". "These 10 proteins can predict conversion to dementia with less than 90 percent accuracy, meaning one in 10 people would get an incorrect result," he said. "Accuracy would need to be improved before it could be a useful diagnostic test." Claim: Study paves the way for a blood test to predict Alzheimer's.

Output: British scientists have identified a set of 10 proteins in the blood that can predict the onset of Alzheimer's and call this an important step towards developing a test for the incurable brain-wasting disease.

Input: Consider Input: Paragraph: "Raising backyard chickens has been satisfying some foodies' affection for the uber-local egg and lower-fat meat in urban areas, including metro Atlanta, for about a decade. Now the Centers for Disease Control is warning of a downside to the popular trend: salmonella outbreaks traced to some backyard owners kissing and cuddling their flocks. The CDC findings drew some media attention last month, and a PolitiFact reader who heard the health alert on NPR's ""Morning Edition"" on July 16 asked us to dig deeper. We went directly to the source, the CDC, which is headquartered in Atlanta and has been investigating four recent Salmonella outbreaks that, as of July 29,had infected 218 people in 41 states. Five of them were in Georgia, 19 were in Alabama, 5 were in North Carolina, 11 were in South Carolina and 6 were in Tennessee. Fifty of the 218 people have required hospitalization for Salmonella, the major symptoms of which are usually diarrhea, fever and abdominal pain. No deaths have been reported, CDC spokeswoman Kristen Nordlund said. So how exactly do CDC officials know that some of these cases are due to backyard breeders kissing and cuddling live poultry? Dr. Megin Nichols, a veterinarian with the CDC, told PolitiFact the agency has been tracking upward trends in both the number of outbreaks and people infected in the past five years and has been working to trace their causes. ""We've been trying to interview these people to find out how they are getting sick,"" Nichols said. ""We are finding a certain proportion that are due to very close contact -- something that surprised us here at the CDC."" Salmonella is a germ that lives naturally in the intestine of chickens, ducks and many other animals. It doesn't typically make the birds sick, but they can transmit the germs in their droppings and on their feet, feathers and beaks, even when they look clean and healthy, the CDC says. The germs also can get on their cages, coops, feed, water dishes, hay, plants and the area where they live and roam. In addition, the bacteria can rest on the hands, shoes and clothes of those who work around the birds or play with them. And Nichols told us that among the people who became ill between 2008 and 2014 due to baby poultry exposure, 49 percent, or 196 out of 400, reported snuggling and holding baby birds. Another 13 percent, or about 53, reported kissing baby birds, she said. Those people, many of whom were young children, became sick through fecal oral contact, Nichols said. Those same interviews also showed that about 46 percent of backyard breeders are keeping live poultry in their homes, she said. Epidemiologic, laboratory, and traceback findings have linked the most recent four outbreaks of human Salmonella infections to contact with chicks, ducklings, and other live poultry from multiple hatcheries. Interviews have been conducted with 140 of those who were recently ill and, 117, or 84 percent, reported contact with live poultry in the week before their illness began, according to the CDC website. Additional interviews to determine whether that contact included snuggling and kissing have yet to be conducted, Nichols said. An increasing number of people around the country are choosing to keep live poultry - mostly chickens, ducks, turkeys and geese as part of a greener, healthier lifestyle. Local governments, including several in metro Atlanta, have changed their zoning ordinances in recent years to accommodate the trend, and groups of backyard poultry buffs meet regularly in the region to talk chicken. Backyard owners have told reporters at The Atlanta Journal-Constitution that the benefits include fresh eggs and meat, a built-in source of fertilizer for their gardens and ready-made bug-killers. Some say they give their chickens names, the freedom to roam the house and yard and cuddle and coddle them like family pets. The larger problem According to the CDC, salmonella, named for an American scientist who discovered the bacteria, is estimated to cause a million illnesses in the United States a year, with 19,000 hospitalizations and 380 deaths. Most people develop diarrhea and the other conditions within 12 to 72 hour after infection and recover without treatment in four to seven days. It has the potential to turn deadly if it spreads from the intestines to the bloodstream, and then to other body sites. Prompt treatment with antibiotics is critical, and the elderly, infants, and people with impaired immune systems are more likely to have a severe illness. In the largest recent outbreak, which occurred between March 2013 and July 2014, more than 600 people in 29 states and Puerto Rico were infected with seven outbreak strains. The outbreak was associated with one brand of chicken, which led to a company recall of more than 40,000 pounds of chicken products, according to the CDC. To prevent salmonella infections related to backyard farming, the CDC's Nichols encourages several common-sense rules. These include thorough handwashing after contact with the chicken, keeping live poultry out of the home, and avoiding snuggling, close contact with the birds' beaks or other close exposure that would allow ingestion of bacteria. She will be one of the experts featured in a webinar on the topic of practicing backyard bird biosecurity at 7p.m. Thursday. Our conclusion The CDC has issued a warning against kissing or snuggling backyard chickens. It follows four recent Salmonella outbreaks that, as of July 29, had infected 218 people in 41 states. Five of them were in Georgia. Interviews have been conducted with 140 of the ill and 117, or 84 percent, reported contact with live poultry in the week before their illness began, according to the CDC website. The CDC also has evidence from outbreaks between 2008 to 2014. In that period, they found that of the people who became infected with salmonella due to baby poultry exposure, 49 percent, or 196 out of 400 people, reported snuggling and holding baby birds. Another 13 percent, or about 53, reported kissing baby birds.. That's cause to sound the alarm." Claim: Caution: Kissing and cuddling chickens can be hazardous to your health.

Output: CDC: Kissing and cuddling backyard chickens linked to salmonella infections

Input: Consider Input: Paragraph: The drugmaker said in a statement there had been an exponential increase in so-called compassionate-use requests for the drug. The spread of the virus in Europe and the United States has "flooded an emergency treatment access system that was set up for very limited access to investigational medicines and never intended for use in response to a pandemic," it said. Gilead said it would keep processing previously approved requests. Remdesivir has been touted by many - including President Donald Trump - as one of the more promising potential treatments for the virus. The company said it was shifting from a system of individual compassionate-use requests to expanded access programs, which it expects will start in a similar time frame that new requests for compassionate use would have been processed. Gilead said it would make exceptions for pregnant women and children under 18 with severe COVID-19, the highly contagious respiratory disease caused by the coronavirus. "Enrollment in clinical trials is the primary way to access remdesivir to generate critical data that inform the appropriate use of this investigational medicine," Gilead said. There are currently no approved treatments or preventive vaccines for COVID-19. Researchers are studying existing treatments and working on experimental ones, but most current patients receive only supportive care such as breathing assistance. Other potential treatments - like malaria drugs chloroquine and hydroxychloroquine - are in short supply as demand has surged with the rapid spread of the outbreak. Some states have already taken steps to limit prescriptions of the drugs to those who need them most. Claim: Gilead puts emergency access to experimental coronavirus drug on hold amid surging demand.
Output: Gilead Sciences Inc said on Sunday it was temporarily putting new emergency access to its experimental coronavirus drug remdesivir on hold due to overwhelming demand and that it wanted most people receiving the drug to participate in a clinical trial to prove if it is safe and effective.
