Although this therapy is not yet available for patient use, the story makes a point of noting that the cost may well be “stratospheric,” should it make it to market. If approved, such treatments are expected to command stratospheric prices. For example, a separate Spark gene therapy for a rare type of childhood blindness, which is on track for Food and Drug Administration clearance soon, could cost $1 million per patient for infusions in both eyes, according to some Wall Street analysts. Still, the therapies can produce at least some offsetting savings. Porteus noted in his editorial that the hemophilia therapy resulted in savings of about $200,000 a year per patient because of the elimination of clotting-factor infusions. The story summarizes the outcome of the small, 10-person trial that dominates this narrative: Lindsey George, the lead investigator and a hematologist at Children’s Hospital of Philadelphia, said that nine of the 10 men in the trial didn’t experience any bleeding episodes after the gene therapy treatment. The one patient who needed clotting factor because of bleeding used 91 percent less than before, she said. Although the story does not address harms directly–and should have–it does note that one of the worrying side effects of gene therapy—spurring the body to attack itself—was not present in this study. It is clear from the story that the study is small and an “early-stage trial.” One source also notes that the researchers tracked individuals in the study for no more than a year and a half, making longer term assessments unavailable. The story could have done more, though, to signal to the reader that, despite the encouraging outcomes of the study, the treatment is still very much under development. The next stage—Phase 3 trials—requires more participants, more careful study design, and takes, on average, three years to complete. The treatment described here, if ultimately proved worthy, could have a profound impact on a serious genetic condition. Independent sources are identified in the story, as are the funders. But missing from the text is information describing linkages between the two funders—Spark Therapeutics and Pfizer—and the lead researchers. It’s not clear from the story that there is a financial relationship. Individuals coping with hemophilia B have few options, and the story describes the main one: injections of blood-clotting factor to stem runaway bleeding. Since the story notes that the research is at an early stage with only 10 participants, a reader can easily infer that the treatment is not yet available. However, additional information about remaining evaluation stages for this treatment would have been a useful reinforcing addition. Hemophilia B sufferers who see this story will likely be contacting their doctors. The story establishes novelty with this: The researchers presented earlier findings on the gene therapy a year ago at the American Society of Hematology’s annual meeting, but the latest data covers a larger patient group and a longer time period. A news release issued by Children’s Hospital of Philadelphia did a good job of describing this study; the Post story could have picked up more of the salient details from that text but reveals independent reporting nevertheless by including sources not connected to the study.
Gene therapy makes a big advance treating hemophilia B blood disorder

Maria Andrade of Cape Verde, Robert Mwanga of Uganda and American Jan Low, who all are from the Lima, Peru-based International Potato Center, and American Howarth Bouis of the international research group HarvestPlus were honored in a ceremony at the U.S. State Department. Kenneth M. Quinn, president of the World Food Prize Foundation, called their work “a breakthrough achievement in developing and implementing biofortification.”  He defined biofortification as “the process of breeding critical vitamins and micronutrients into staple crops, thereby dramatically reducing hidden hunger and improving health for millions and millions of people.”  The honorees’ work has focused on the orange-fleshed sweet potato, an important source of vitamin A, especially in sub-Saharan Africa. Vitamin A deficiency, especially there and in Asia, is a cause of blindness and premature death, according to the International Potato Center, an agriculture research center based in Lima, Peru. “The impact of the work of all four winners will be felt around the globe but particularly in sub-Saharan Africa,” said Gayle Smith, head of the U.S. Agency for International Development. The prize is awarded annually by the World Food Prize Foundation for food and agriculture innovation. The scientists will share the $250,000 prize equally and it will be awarded at a ceremony during World Food Prize week in Des Moines, Iowa, in October, when the prize will celebrate its 30th anniversary. Past recipients include John Kufuour, a former president of Ghana; former U.S. Senators Bob Dole and George McGovern; and Grameen Bank founder and Nobel laureate Dr. Muhammad Yunus of Bangladesh.

"On Nov. 27, 2013, a Madison-based liberal advocacy group used a mass email to promote protests that were planned against Walmart stores for two days later -- Black Friday. The demonstrations aimed to ""expose Wal-Mart’s shameful labor practices and support workers,"" according to One Wisconsin Now, which then made this claim: ""The Walton family, which owns Wal-Mart, controls a fortune equal to the wealth of the bottom 42 percent of Americans combined."" That reminded us of a March 2011 claim by filmmaker and liberal activist Michael Moore. He said in a Madison speech that 400 Americans have more wealth than half of all Americans combined. Based on online hits, it became one of our most popular fact-checks ever. So we wondered about the Walmart claim. Wealth, not income In the days before and after Black Friday, leaders no less prominent than President Barack Obama and Pope Francis decried the extent of income disparity in the United States and around the world. Obama called the growing income gap a ""defining challenge of our time."" The pope said that while the earnings of a minority ""are growing exponentially, so, too, is the gap separating the majority from the prosperity enjoyed by those happy few."" Walmart, of course, is a big target. According to Forbes, as of May 2013 the international retailer had $469 billion in sales and 2.2 million employees, including 1.3 million in the United States. The corporation has been criticized for low wages; and in December 2012, PolitiFact National rated as Mostly  a claim that more Walmart employees are on Medicaid and food stamps than other companies. But let’s be clear up front: Although income and wealth are related, they’re not the same. Wealth is commonly measured in terms of net worth -- the value of a person’s assets minus liabilities. So, things like savings and retirement accounts, minus what is owed on a home mortgage, credit cards, etc. That means a person with heavy debt can have little wealth, or negative wealth, even while earning a six-figure income. One more point before we get to the wealth figures. Walmart was founded by the late Sam Walton, who opened the first store in Arkansas in 1962. Walmart incorporated in 1969 and became a publicly traded company a year later. So, Wal-Mart is not family owned, but rather owned by its stockholders; on the other hand, according to Bloomberg and other news reports, the Walton family members still have control of the company, owning about half of the shares. Group's evidence Scot Ross, One Wisconsin Now's executive director, told us his evidence to back his group’s claim is a July 2012 article by economist Josh Bivens, research and policy director of the liberal Economics Policy Institute in Washington, D.C. Bivens wrote that in 2010, the wealth of six Walton family heirs was $89.5 billion, 22 percent higher than in 2007. Meanwhile, the median wealth of American families in 2010 was $77,300, nearly 39 percent lower than three years earlier. (Median wealth refers to the American family that is exactly wealthier than half of all families and less wealthy than half.) As for measuring one against the other, Bivens said the Walton family wealth in 2010 was as large as the wealth of the bottom 48.8 million families in the United States, or 41.5 percent of all American families. Rounded up, 41.5 percent would be 42 percent, the figure One Wisconsin Now claims. But let's keep shopping around a little. Similar claim It turns out that a statement nearly identical to the one made by One Wisconsin Now was uttered in July 2012 by U.S. Sen. Bernie Sanders, a Vermont independent who caucuses with Democrats. Sanders said the Walton family owns ""more wealth than the bottom 40 percent of America,"" a claim PolitiFact National rated . Our colleagues found that Sylvia Allegretto, a labor economist at the University of California, Berkeley, compared the Waltons’ cumulative net worth with that of the overall population, as cited in the Federal Reserve’s Survey of Consumer Finances. That survey was published in August 2012. Allegretto found that the Waltons’ wealth in 2010 was valued at $89.5 billion -- equal to the entire bottom 41.5 percent of American families. The 2010 figures are the latest available for doing comparisons with the net worth of the overall population. But we found, using the Forbes 400 list for 2013, that the wealth of six of Sam Walton’s descendants has continued to grow. Here are their rankings and their wealth: No. 6 Christy Walton (daughter-in-law), $35.4 billion No. 7: Jim Walton (son), $33.8 billion No. 8: Alice Walton (daughter), $33.5 billion No. 9: S. Robson Walton (son), $33.3 billion No. 95: Ann Walton Kroenke (niece), $4.7 billion No. 110: Nancy Walton Laurie (niece), $4 billion Total Walton family wealth: $144.7 billion. A note before we close: Allegretto told us the housing crisis is a key reason that the gap between the Walton family wealth and the wealth of other American families has grown. More Americans were left with ""negative wealth"" because they lost their biggest asset -- their home -- and often significant amounts of their savings, as well, she said. Our rating One Wisconsin Now wrote: ""The Walton family, which owns Wal-Mart, controls a fortune equal to the wealth of the bottom 42 percent of Americans combined."" For comparison purposes, the latest data available, for 2010, the figure is 41.5 percent. To comment on this item, go to the Milwaukee Journal Sentinel's website."
