Q: 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.

A: 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.

Q: Paragraph: Posthumous sperm donation is technically feasible and morally acceptable, the specialists said in a review published in the Journal of Medical Ethics on Tuesday. They argue it should be seen like organ and other tissue donations as a way of relieving the suffering of others. While infertility is not life-threatening, said Nathan Hodson of Britain's Leicester University and Joshua Parker of Britain's Wythenshawe Hospital in Manchester, it causes great suffering and could be said to be a form of illness. "If it is morally acceptable that individuals can donate their tissues to relieve the suffering of others in 'life enhancing transplants' for diseases ... we see no reason why this cannot be extended to other forms of suffering like infertility, which may or may not also be considered a disease," they said. Such a move would raise questions about consent and family permissions for posthumous donations, Parker and Hodson said, and there would also be concerns about anonymity of the donor. Britain has a shortage of donor sperm, while demand is high, and increasing, the experts said. They cited government data showing that an estimated 4,000 samples are imported to Britain each year from the United States, and 3,000 from Denmark, as well as more from other European Union countries. Sperm can be collected after death either through electrical stimulation of the prostate gland or with surgery. It can then be frozen and stored until required. Parker and Hodson cited studies showing that sperm harvested from dead men can result in healthy pregnancies and children with normal health and development, even when the sperm is retrieved 48 hours after death. Other medical experts said the analysis raised issues that need to be resolved. "Further discussion is needed to understand whether people who need to use donor sperm would even want to use the sperm of a deceased donor," said Sarah Norcross, director of the Progress Educational Trust. "It is also vital to seek the opinions of donor-conceived people about what they think the impact would be of never being able to meet the donor." Claim: Posthumous sperm donation should be allowed, say UK experts.

A: Men in Britain should be allowed to donate sperm after they die to meet growing demand from couples seeking fertility treatment, medical experts say.

Q: Paragraph: The story quotes an expert who states that exercise is 'cheap', which is generally true, but can vary depending on the type of exercise. The exercises included in most of the studies examined were taught and supervised by trained individuals, which can increase the cost. The story does not provide any data (either relative or absolute) about the benefits of exercise and other approaches to managing these injuries. This was probably appropriate, because outcomes are defined in different ways depending on the study, but the story author might have explained it. We'll give the story the benefit of the doubt and grade it satisfactory. The potential harms of exercise in the context of repetitive strain injuries, such as making the injury worse, are not mentioned. The story accurately describes the original article as a review of studies, but it misstates the authors' conclusions and makes it appear that exercise was far more effective than ergonomic approaches. In the original review, 8 of 14 studies looked at the effects of exercise compared with no treatment, and the authors state that here they found conflicting evidence of the effectiveness of exercise. The story inaccurately states that 'the majority found positive results.' Although the authors reported that the evidence for ergonomic adjustments such as special keyboards was also conflicting, the story says that evidence of their efficacy was limited. It should also have stated that most of the 22 studies reviewed were rated as poor quality by the reviewers, and that 103 of the 126 references reviewed were rejected for various reasons. The story states that the direct and indirect costs associated with repetitive strain disorders are as much as $100 billion dollars annually in the U.S. The original article actually estimated these costs at about 1/50 that much, or $2 billion. This exaggeration of impact is a form of disease-mongering. Story quotes the lead author of the review as well as other experts, whose affiliations are provided. The article correctly states that many types of exercise have been studied for repetitive strain injuries. However, rather than "hiking, cycling, walking, swimming and yoga," as stated in the article, the studies examined generally were investigating the effects of prescribed exercises in a supervised context. The story mentions that exercise in various forms has been studied as a potential therapy for repetitive strain injuries for many years and is not new. The story does not appear to have relied solely or largely on a news release. Claim: Exercise may be the Rx for RSI

A:
This story may leave the reader with the impression that the evidence in support of exercise as a treatment for repetitive motion injuries is more consistently positive than it really is. The lead author of the literature review is quoted as saying that it's not possible to draw firm conclusions, yet the story depicts exercise as 'the best medicine' for these (sometimes) work-related complaints. The evidence for the value of exercise was actually found to be similar to that for the value of ergonomic approaches such as specially designed keyboards. In both cases the authors found conflicting evidence that these strategies help. While the difference in wording (conflicting versus limited evidence) may seem like splitting hairs, limited evidence means that positive outcomes were found in one well-designed trial, or consistently positive findings across multiple trials. On the other hand, conflicting evidence means that outcomes across trials were inconsistentsometimes positive, sometimes showing no effect at all or perhaps even a negative effect. The story might have done better to highlight how little is actually known about what works for these disordersparticularly in light of how much money is spent to address them. Most of the reviewed studies were poor quality and too small to draw any valid conclusions. While quoting experts who assert that various approaches can help makes for an interesting story, it doesn't reflect what the available research showsand so may not be as helpful as the writer may have intended.
