Paragraph: There’s no discussion of cost, even to mention that statins are relatively inexpensive these days and are mostly generically available. To its credit, the article does mention the cost of a calcium scan. We learn that “anywhere from 50 to 200 healthy people need to take a statin daily to prevent a single heart attack for five years.” That’s helpful information. It also notes that the observed benefit is less for older patients. The story could have added that even those numbers might disputed by some experts who perceive no meaningful benefit. For example, one review found being on a statin does not help people with low risk for heart disease live longer. The story does a service by highlighting the harms of statins. It explains: “The most common side effect of these drugs is muscle pain, which usually goes away if patients stop taking the medicines. People taking statins are also at a higher risk of developing diabetes, which is harder to reverse.” It also mentions the potential for overtreatment with the use of coronary calcium scans. However, we wish it had included absolute numbers. The story says harms are “uncommon,” but provides no data to back that up. Rates of adverse effects with statins have been measured at 1 to 10%, which makes them “common” in the definition of the European Medicines Agency. Also noteworthy is that some contend that adverse effects of statins have not been reliably reported. The story doesn’t explain the quality of the study, or of studies on which current guidelines are based. We don’t explicitly learn that this is a modelling study. In other words, this study consisted mostly of reinterpretations of math, not re-evaluations of real-life patients. The researchers said they were unable to obtain enough data on all possible harms and age-specific data on some harm outcomes, “so the risk thresholds we determined may still be too low.” There is no disease-mongering here. This story includes sources that weren’t involved in the study. The study’s authors reported no conflicts of interest. The story could have acknowledged the influence of pharmaceutical companies in creating guidelines for statin use. The alternative of not taking a statin was the key message here, and that’s laudable. However, we have a couple of concerns. First, we learn that “some statins were more effective than others, with atorvastatin (the generic name for Lipitor) being the best of the bunch.”  However, the story doesn’t explain on what basis some statins are “more effective.” In fact, some statins may be more effective at lower cholesterol, but the study found that no statin rises above others when it comes to the outcomes that counts most to patients — reducing cardiovascular deaths. Also, the story doesn’t mention lifestyle interventions — diet and exercise. The story makes it clear that statins are widely prescribed. The story states this an attempt to better weigh the benefits and harms of statin use. There was a good range of interviewees with no reliance on a news release Claim: Before Starting A Statin, Talk It Over With Your Doctor

Ex Output:
The story reports on a study that re-assessed who benefits from taking a statin to prevent heart disease, with different risk thresholds based on sex, age group, and statin type. It reports the view that current guidelines “haven’t adequately considered” the harms from taking these widely used drugs. The story laudably focuses attention on potential adverse events and a need for balanced decision-making. It also incorporated a variety of sources. In our view, the story could done a better job in discussing costs, the quality of evidence, and alternative strategies to prevent heart disease. Statins are among the most widely prescribed drugs, with their use encouraged under guidelines such as those of the American Heart Association of the American College of Cardiology. However, data isn’t crystal clear on the benefits and harms of statins for people who don’t already have heart disease. As a result, there’s concern that they are being overused. It’s laudable that some news organizations — including CNN as well as NPR — highlighted research that explores these complexities and points out the need for patients and physicians to weigh benefits and harms. The headline of this story is, in our view, a winner.

Paragraph: With global warming widely expected to slash snowfall, especially at lower levels, the Swiss tourism industry is looking for ways to preserve a lucrative business brutally exposed to the weather. Enter Napa, Serbia’s last circus bear. The Arosa ski resort in eastern Switzerland has created a $6.5 million refuge hosting Napa and two other bears rescued from cages at restaurants in Albania to help draw summer visitors and reduce its reliance on skiers and snowboarders. School classes, families and a group of army veterans celebrating an 80th birthday were visiting one recent summer day, helping the park toward what Arosa tourism director Pascal Jenny said was a target of 50,000 visitors this year. Arosa has reinvented itself before - moving to winter tourism in the 1930s after decades as a health resort for tuberculosis patients. But with nearly 620,000 overnight stays in winter last year, more than three times the summer total — it will not be easy. Jenny, who fears a sharp decline in snowfall over the next 20 or 30 years, is hedging his bets. “What gives us some hope is that artificial snow is making strong technical advances. I can make snow now at 5 degrees above freezing,” he said, standing on an observation platform beside the Weisshorn cable car which gives a sweeping view of the snow-capped Alpine valley. His two-pronged approach highlights the dilemma faced by mountain resorts — how to retain profits as they embark on what the Organisation for Economic Co-Operation and Development (OECD) says needs to be a global rethink of tourism. “The consequences of climate change will be felt across the travel and tourism sector over the coming decades,” the OECD, whose member countries represent 80% of the world’s trade and investment, said in a 2018 study of megatrends in tourism. Storms, flooding and tidal surges will threaten coastal regions, southern destinations face extreme heatwaves and northern ones will see shorter periods of snowfall, it said. Mountain resorts tend to be higher in Switzerland than in Austria or France, giving them better chances as snow becomes scarcer. But even at 3,000 meters, pistes could see snow depths more than halved by 2100 if greenhouse gas emissions are not curbed, a report in The Cryosphere, a peer-reviewed geosciences journal named after the frozen water parts of the Earth, said. Resorts below 1,200 meters - as about a quarter of Alpine ones are - might get almost no snow, said the 2017 report, whose title starts “How much can we save?”. Snow levels will gradually stabilize if global temperature rises are contained, it says. Arosa is 1,775 meters up but Jenny worries that a loss of snow in the lowlands will cost it visitors because people will lose their emotional connection with snow. “That is almost more dangerous for the sector,” he said. Hence his interest in an industrial estate in Denmark, where Arosa is cooperating on a project to make artificial snow so that urban dwellers can learn to ski and then, he hopes, go on to hone their skills in the Alps. The economics are clear: a daily lift pass for skiers in Arosa costs 79 Swiss francs ($80.27), while a summer hiker or mountain biker typically pays 18 francs for a pass that lets them use a rope park, a swimming area and paddle boats on the town’s lake. Hotels and restaurants charge more in winter too, but the strong Swiss franc has priced many people out. Switzerland is one of the wealthiest countries in the world, and the Swiss government says the long-term outlook for tourism is healthy. “Mountain summers can position themselves as an alternative to the Mediterranean regions,” a 2017 report said. Summer tourism already accounts for 60% of overnight stays across Switzerland, but the season brings in only 18% of revenue, said Therese Lehmann, an economist at the University of Bern’s Centre for Regional Development. Government data already shows a 24% drop in skiers in the decade to 2016, with other factors as well as climate change. “The decline of ski tourism — a powerful economic engine — will have more of an impact than the additional revenue in summer,” said Dominik Siegrist, director of the Institute for Landscape and Open Space at Switzerland’s University of Applied Sciences Rapperswil. Europe’s population is aging and younger people are less interested in skiing. Snowshoeing, winter hiking, sledding and ski touring — in which people hike up mountains, are on the increase, industry lobby Swiss Tourism says. Consolidation of winter tourism is on the horizon, with overnight stays in bigger Swiss resorts up 1 percent in the decade to 2015, but down 17 percent in smaller ones. “Lots of smaller ones are grasping at straws, trying to survive as long as they can because the valleys depend on this tourism,” Siegrist said. Large resorts in the Swiss cantons of the Grisons and Valais, Austria’s Tyrol province and France’s Savoie region have the marketing pull to survive, Siegrist said, listing high- altitude Andermatt, Zermatt and St Moritz in Switzerland. The Andermatt Swiss Alps resort, in central Switzerland, is targeting cyclists in summer, and has also built new lifts to lure winter sports fans. It covers a nearby glacier with strips of artificial fleece in spring to help reduce melting and creates piles of snow higher than houses to deploy on ski pistes as early as November to avoid having to use expensive artificial snow. The strong Swiss franc has hit ski lifts focused on winter business from European visitors hard in the past 10 years, the government says, but the minority of lifts with strong summer business are booming thanks to visitors from overseas. Many smaller lift firms get cheap loans and, increasingly, state subsidies to help balance the books, said Lehmann. Roughly a third are debt-free, but depend on long-haul tourism, which she said was not ideal from an environmental point of view, because flights are a major contributor to holiday carbon emissions. “Maybe we have to get away from focusing solely on growth, and promote Alpine areas as good habitats for living, not just for tourism,” she said. Listed cable car companies Bergbahnen Engelberg Truebsee Titlis Bet AG (TIBN.S) and Jungfraubahn Holding AG (JFN.S), cite year-round visitors from Asia - especially China and India - as important sources of income. Asked about sustainability, Titlis marketing director Peter Reinle said the firm’s prospects were good for the next 50 years. “We as a single entity can not solve the whole climate problem. Politicians have to provide framework conditions.”  Jungfraubahn’s Corporate Secretary Christoph Schlaeppi said it employed 800 local people, helping to make life in the mountains economically sustainable for a new generation. The government says it is up to individual resorts to decide how much they want to attract Asian groups, but focuses its own promotion efforts on individual travelers and sustainability, noting Japanese tourists now come independently and stay longer. “We have to see that guests from Asia making the long flight to Europe or Switzerland stay as long as possible,” Richard Kaempf, head of tourism policy at the State Secretariat of Economic Affairs, told Reuters. While the government encourages year-round use of mountain infrastructure, he said it is not giving up on winter sports, a deep cultural touchstone for the Swiss. But he acknowledged the growing challenge of lowlanders losing the “winter feeling”. Claim: High and dry: Alpine resorts grapple with climate change.

Paragraph: Most of the pillar coral that her team have been monitoring for years are dead. Hower and her colleagues are on a race against time to find what causes a disease dubbed Stony Coral Tissue Loss Disease, which since 2014 has been raging like an inferno through reefs under the deceptively calm blue paradise of the Caribbean. In just five years, it has wreaked devastation on the fragile coral ecosystems that are already at risk of extinction from the effects of climate change. Of 40 reef sites in the Florida Keys monitored by the Florida Fish and Wildlife Conservation Commission, 38 are already affected. “It is a huge disaster that’s going on underneath the waves,” says Karen Neely, a coral ecologist at Nova. “This is on the level of the Amazon burning. It is on the level of a disease that’s wiping out all of America’s forests.”  Stony Coral Tissue Loss Disease attacks the tissue of coral, transforming healthy, vibrant marine ecosystems into drab, dead worlds within weeks. The disease has ravaged much of the Atlantic reef off Florida, spread across parts of the Caribbean, and has recently been reported near Belize in central America. Pillar coral, whose clusters of spiky fingers appear to reach up from the sea bed, is “reproductively extinct” off the Florida coast, says Keri O’Neil, chief coral scientist at the Florida Aquarium. At the aquarium, a rare ray of hope comes from a room that has the lights off for much of the year. Here, an elaborate and expensive system of LED lights is designed to emulate sunrises, sunsets and phases of the moon to coax pillar coral in tanks into reproducing as if they were in the ocean. Neely’s team has also been laboriously applying a paste combined with amoxicillin to the coral, which they say has been effective in treating the disease. Stony Coral Tissue Loss Disease kills over 20 species of coral, including most of the important ones that build the reef, hold it together and protect the shoreline, says Neely. Scientists are working together to try to find solutions. A Disease Advisory Committee has been set up to help coordinate and scientists are performing fieldwork to bolster each others’ research. They are, they say, like first responders at the scene of a disaster. Despite that, little is known yet about what causes the disease. In Sarasota, Erinn Muller and her team at the Mote Marine Laboratory’s Coral Reef Research & Restoration Center are among those trying to identify the pathogen behind it and how it spread from Florida to the Caribbean. “We’re getting these jumps and so that would suggest that there’s some type of human influence that is allowing that jump to occur,” says Muller. Near the start of 2019, it was spotted off the coast of the Virgin Islands. There, Marilyn Brandt of the University of the Virgin Islands’ Center for Marine and Environmental Studies and her graduate students are ripping out the diseased coral to try to stop it spreading. Her team - like Neely’s and others - are joining forces and working frantically to prevent the loss of this delicate and complex underwater world, with its iridescent colors and rippling textures. Such a loss would represent “a loss of biodiversity which could be a source for future medicines, the loss of fisheries, the loss of tourism value,” says Brandt. “A lot of Caribbean islands have part of their culture based around coral reefs and if you lose those reefs you lose an aspect of their culture.”  Photo essay here reut.rs/2lfuEtX Claim: Disaster under the waves: the race to save the coral of the Caribbean.
