Example Input: Paragraph: U.S. Marines of Weapons Company, 1st Battalion, 3rd Marines are silhouetted against the sunset during a joint patrol with Afghan National Army (ANA) soldiers along Helmand river near the Camp Gorgak in Helmand province, southern Afghanistan, July 3, 2011. REUTERS/Shamil Zhumatov The study, published in the Archives of Pediatrics and Adolescent Medicine, analyzed medical records of 307,520 children of active-duty Army personnel, aged 5 to 17 years old. It found almost 17 percent of them exhibited mental health problems. “Children of parents who spent more time deployed between 2003 and 2006 fared worse than children whose parents were deployed for a shorter duration,” the study’s researchers wrote. The lead researcher was Alyssa Mansfield, who was at the University of North Carolina at Chapel Hill at the time the study was conducted. The U.S. Army reported some 562,000 members in active duty and more than 570,000 children of such members in 2010. Just under two-thirds of all active-duty servicemen and women were married and 15 percent were raising children as single parents. The children whose parents deployed at least once, for an average of 11 months, as part of the U.S. Operation Iraqi Freedom or Operation Enduring Freedom in Afghanistan were especially likely to suffer from adjustment, behavioral, depressive or stress disorders than those whose parents never went to war, the study found. Boys were more likely to have mental health problems than girls, according to the report, which reviewed records for patients cared for at military medical facilities and at civilian facilities using military medical insurance. “We used to think about deployment as a single experience: I go, I’m away, it’s difficult and then I come back. Well, it’s a way of life in the military that deployments continue to occur and families have to manage the consequences,” said Dr. Stephen Cozza, psychiatry professor at the Uniformed Services University of the Health Sciences. Cozza has studied the issue and wrote an editorial accompanying the report. “These are consequences that aren’t necessarily short-term,” he said. The challenges don’t necessarily end with the final return home, he said, as soldiers may bring back their own mental health issues which affect relationships with their children. Claim: Mental problems of soldiers' kids tied to wars.
Example Output: The longer U.S. soldiers were deployed in Iraq or Afghanistan, the more likely their children would be diagnosed with mental health problems, according to a study published Monday.

Example Input: Paragraph: Keytruda is already approved as a cost-effective treatment in melanoma and the National Institute for Health and Care Excellence also on Dec. 2 approved its use in the treatment of lung cancer patients who had started on chemotherapy, after Merck & Co cut the price further for the NHS. But trial data so far on the survival benefit of Keytruda as an initial lung cancer treatment has not been reliable enough,   according to NICE’s draft guidance, which will be subject to public consultation until 21 March. “The exact size of the overall survival gain for Keytruda compared to the current standard of care was uncertain because of the immaturity of the data,” a NICE spokeswoman said. Keytruda has proved effective in fighting non-small cell lung cancer in patients with high levels of a protein called PD-L1, which makes them more receptive to immunotherapy. The average cost of a course of treatment in Britain is around 29,000 pounds ($36,000) at the full list price but the NHS will pay less after getting a confidential discount. ($1 = 0.8042 pounds) Claim: UK rejects Merck's Keytruda as initial treatment for lung cancer.
Example Output: Britain’s healthcare watchdog NICE, which assesses the cost-effectiveness of medical treatments, has stopped short of recommending the use by the National Health Service (NHS) of Merck & Co Inc’s immunotherapy drug Keytruda in newly diagnosed lung cancer patients, after giving the go-ahead in December for patients who had prior treatment.

Example Input: Paragraph: P&G, with roughly $68 billion in annual revenue, said it has invested millions in creating and testing refills for detergents over the years and is now trying to push in to mainstream beauty and body care refills – which are virtually  unheard of. It recently began offering some Olay face-cream jars with refill pouches on Olay.com, telling Reuters it has plans to expand the sales of the pouches in Europe early next year. “We’re learning on our legs so I don’t know that we’re in a position to say, ‘Hey, here’s the magic to selling refills,’” P&G spokesman Damon Jones said. Beauty products retailer The Body Shop, owned by Brazil’s Natura Cosmeticos SA NATU3.SA, says it plans to roll out “refill stations” in its stores globally next year, allowing shoppers to buy reusable metal containers to fill with Body Shop shower gels or creams. The company had offered refills at its stores in the early 1990s, but discontinued them in 2003, citing a lack of consumer demand. Unilever, which has set targets for reducing and recycling plastic by 2025, in October announced the planned launch of “refill sticks” of deodorants under its Dove line of personal care products on Loopstore.com. The website, operated by recycling company TerraCycle, offers consumers the chance to buy some household products in ultra-durable packaging with refills delivered to their doors, milkman-style. Across the consumer goods industry, results for refillable products have been mixed so far as many shoppers are far too set in their ways to be easily weaned from living in a throwaway culture. While refills are less expensive to purchase - generally priced at 20% to 30% less per item than the containers they are aimed to replenish, according to Unilever - shoppers have so far, for the most part, failed to snap them up, the companies said. SC Johnson & Son Inc, marketer of Windex and Pledge, said refills and concentrates so far have not played well with either Americans or Europeans over the decade they have been offered, with unit sales of such products pretty much flat. It pulled concentrated refills for Shout stain remover off the shelves because they were not selling very well. In 2010, Unilever put 20-liter tanks to dispense detergents in Walmart Inc’s (WMT.N) British supermarket chain Asda, and provided flexible pouches for customers to refill. But with leaky machines, safety and maintenance problems and the high costs of upkeep, Unilever said the tests fell short of expectations. Asda was also unhappy because the tanks occupied a lot of space. “None of them sell very well – it is a convenience issue,” SC Johnson CEO Fisk Johnson told Reuters. Johnson said some people find it painstaking to wash and refill bottles themselves while others worry that smaller bottles filled with concentrates are less “bang-for-your-buck” than the larger ones they have used for years. Still, the privately held company said it was expanding its refill offerings this year to address concerns surrounding plastic waste and is also testing refill stations for cleaning products with UK retailer Waitrose, owned by Britain’s John Lewis [JLPLC.UL]. The Waitrose tests are showing the first signs of progress in refill sales, Johnson said, and the company is now thinking of expanding the project. Even if consumers are comfortable using refills for some household goods, it is more complicated to sell them for products like Pantene shampoo and Olay creams, P&G spokesman Jones said. For instance, with beauty products, the look and feel of packaging is a big factor in creating and maintaining customer loyalty, while delivering an environmental benefit, he said. Some shoppers say they want to buy refillable products, but that the offerings are not available at many stores. Earlier this year, dozens of consumers took to social media to urge The Body Shop to bring back its refill counters. “Refill, refill, refill!” Twitter user @JaiChipperfield said on July 22, joining a thread in which several other shoppers demanded the return of refills. “Seems to me that judging by these comments your customers want to see the return of refills,” @JaiChipperfield added. “Me too, it would be brilliant to see that return.”  The Body Shop eventually responded to those pleas. “Now with the renewed focus on sustainability, we believe it is the right time to return with it,” Body Shop spokeswoman Lucy Muircroft told Reuters this week. Claim: Procter & Gamble, rivals take refills into beauty aisle.
Example Output:
Under pressure to reduce environmental waste from single-use containers, major consumer companies including Procter & Gamble Co (PG.N), Unilever Plc (ULVR.L) and The Body Shop are rolling out more products in refillable form.
