[EX Q]: Licenses for hemp cultivation topped a half-million acres (200,000 hectares) last year, more than 450% above 2018 levels, so there's intense interest in the rules the U.S. government is creating. Critical comments on the draft have poured in from hemp farmers, processors, retailers and state governments. Growers are concerned the government wants to use a heavy hand that could result in many crops failing required tests and being destroyed. The U.S. Department of Agriculture, the agency writing the rules, estimates 20% of hemp lots would fail under the proposed regulations. "Their business is to support farmers and not punish farmers and the rules as they're written right now punish farmers," said Dove Oldham, who last year grew an acre (0.40 hectares) of hemp on her family farm in Grants Pass. "There's just a lot of confusion, and people are just looking for leadership." The USDA did not respond to the criticism but has taken the unusual step of extending the public comment period by a month, until Jan. 29. The agency told The Associated Press it will analyze information from this year's growing season before releasing its final rules, which would take effect in 2021. Agricultural officials in states that run pilot hemp cultivation programs under an earlier federal provision are weighing in with formal letters to the USDA. "There are 46 states where hemp is legal, and I'm going to say that every single state has raised concerns to us about something within the rule. They might be coming from different perspectives, but every state has raised concerns," said Aline DeLucia, director of public policy for the National Association of State Departments of Agriculture. Most of the anxiety involves how the federal government plans to test for THC, the high-inducing compound found in marijuana and hemp, both cannabis plants. The federal government and most states consider plants with tiny amounts 0.3% or less to be hemp. Anything above that is marijuana and illegal under federal law. Yet another cannabis compound has fueled the explosion in hemp cultivation. Cannabidiol, or CBD, is marketed as a health and wellness aid and infused in everything from food and drinks to lotions, toothpaste and pet treats. Many have credited CBD with helping ease pain, increase sleep and reduce anxiety. But scientists caution not enough is known about its health effects, and the U.S. Food and Drug Administration last year targeted nearly two dozen companies for making CBD health claims. Still, the CBD market is increasing at a triple-digit rate and could have $20 billion in sales by 2024, according to a recent study by BDS Analytics, a marketing analysis firm that tracks cannabis industry trends. About 80% of the 18,000 farmers licensed for hemp cultivation are in the CBD market, said Eric Steenstra, president of the advocacy group Vote Hemp. The remaining 20% grow hemp for its fiber, used in everything from fabric to construction materials, or its grain, which is added to health foods. But hemp is a notoriously fickle crop. Conditions such as sunlight, moisture and soil composition determine its ratio of THC to CBD. Choosing the right harvesting window is critical to ensuring it stays within acceptable THC levels. Under the draft USDA rules, farmers have no wiggle room. They must harvest within 15 days of testing their crop for THC, and the samples must be sent to a lab certified by the U.S. Drug Enforcement Administration. Samples must be from the top of the plant, where THC levels are highest, and the final measurement must include not just THC, but also THCA, a nonpsychoactive component. Crops that test above 0.3% for the two combined must be destroyed. Growers with crops above 0.5% would be considered in "negligent violation," and those with repeated violations could be suspended from farming hemp. In addition, a pilot program for federal crop insurance that would be available to hemp growers in some states specifies that crops lost because of high THC levels won't be covered. Those provisions are causing alarm among growers and states with pilot hemp programs allowed under the 2014 Farm Bill. Some states allow THC levels above 0.3%, and not all include THCA in that calculation. Many permit more harvesting time for growers after THC testing. Farmers are lobbying for a 1% THC limit and a 30-day harvest window to give them more flexibility while remaining well under THC levels that can get people high. The draft regulations don't "seem to be informed by the reality of the crop," said Jesse Richardson, who with his brother sells CBD-infused teas and capsules under the brand The Brothers Apothecary. "If no one can produce (federally) compliant hemp flower, then there will be no CBD oil on the market." Growers are also worried about the proposed rule requiring that all THC testing be done in a DEA-certified lab because there are so few of them. Some states have only one, which would serve hundreds of growers in a short harvest window. Samantha Ford, a third-generation farmer in North Carolina, waited two weeks to get back THC results from a lab last fall and then spent 45 days harvesting her 1 acre (0.40 hectares) of hemp by hand. "The 15-day window that's not feasible, and that was on a small scale," she said. "I can't imagine farmers who have acres and acres and acres of it." Concerns also have emerged about the workload the draft rules would place on states. Many do random sampling for THC levels, but the USDA would require five samples from every hemp lot a burden for state agricultural departments, said DeLucia, of the national ag agencies group. If federal rules are too onerous and expensive, some states might drop their hemp programs. In those cases, farmers would have to apply for licenses with the USDA, and at this stage it's unclear how U.S. officials would manage or pay for a nationwide licensing program, DeLucia said. Under the 2018 Farm Bill, the USDA must approve state plans for hemp programs. Louisiana, Ohio and New Jersey last month were the first to get the green light but those plans might need to be reworked after final rules are written. "What we don't want to see is states having to write their rules and then have to change the rules again and rewrite them" after 2021, said Steenstra, of Vote Hemp.

[EX Q]: A skier takes a jump during sunny winter weather at the Swiss mountain area of Hoch-Ybrig, south of Zurich, February 23, 2011. REUTERS/Arnd Wiegmann Lisa Wheeler, a New York-based fitness instructor, believes it's never too late to get in shape to make skiing more enjoyable and safe. But don't overdo it. "Do some basic strength training for the legs, core and arms," said Wheeler, fitness program director for DailyBurn, an online workout site. "But if you haven't done anything, dial it back a little." Wheeler recommends lunges to strengthen the quadriceps, the long muscles in the front of the thigh. "Lunges are quad-dominant and skiing is very quad dominant because your knees are bent and you're going downhill," she said. "And lunges also work the hamstrings and glutes," she explained, referring to the large muscles that form the buttocks. Wheeler thinks the novice can forgo jumping or hopping lunges and concentrate instead on matrix lunges, basically stepping to and pushing off different directions across the range of motion. "For the last-minute person I recommend taking it easy," she said. Wheeler said people think of skiing as going in one direction, downhill, and neglect to prepare their hips and core for the considerable demands of the activity. "If you analyze skiing there's a lot of rotation and lateral movement of the hips," she said. "I would do some core exercises, such as planks, and rotational movements with the medicine ball," she said. "Because going down the slopes your body is turning, your hips are turning." Jessica Matthews of the American Council on Exercises suggests exercises that mimic the activity of skiing, which along with cardiovascular fitness and muscle strength, demands a measure of speed and agility. "I'm a huge fan of cone drills," she said. "I just picked up a set for the house." Sold in sporting goods stores, cones are smaller and lighter than traffic cones. Matthews, an exercise physiologist, thinks they are ideal for setting up a circuit to train for the movements of weaving down a mountain. "You can work on developing lower body strength, lateral movements, do cone jumps and practice proper landing," she said. Squats and lunges build lower body strength but for those challenged by a full squat, Matthews suggests the wall sit, which is essentially placing the back against the wall with knees bent. Ideally, she said, you want to begin a pre-ski routine at least six weeks prior to hitting the slopes. "That's a good time from physiological standpoint," she said. Another crucial element to skiing is the ability to react quickly. "Downhill is not straight downhill," said Matthews. "You have to dodge people. You've got to be able to make quick changes, you might have to counter a fall, so it's important to make sure your hips, legs, shoulders, spine are all ready to go." Wheeler said.

[EX Q]: Although the article notes that current desensitization efforts involving time-consuming immune system drug infusions to stifle rejection antibodies add up to $30,000 to the cost of a transplant, it does not make any estimate of the cost of the enzyme infusion that was the subject of the "novel" approach described in the new study. Based on later comments, it is presumed to cost about $65,000. The story does an adequate job of noting the actual numbers of patients in the study group, the absolute number that were able to have a successful transplant and the absolute number who later had a rejection episode that required standard anti-rejection therapy. Although the article makes clear the patients were "successfully treated" if sensitizing antibodies returned, it does not give any information about side effects, from the enzyme infusion nor the anti-rejection drugs subsequently used. To its credit, the article does emphasize that the long-term value of the new therapy is open to question and that far more work needs to be done to answer questions about quality, safety, efficacy and cost. The article tells us little about the people who participated in the clinical trial, such as type and duration of previous disease treatment, age, gender, race, co-morbidities, insurance status and so on. Nor will the reader get a really clear idea of how healthyor illpatients have done on other desensitization protocols overall and in the long term. No mongering here. The article duly discloses that the study was conducted or somehow supported by Hansa Medical, the maker of the enzyme infusion, and quotes at least two experts not involved in the study itself. The story mentions the existence of other desensitization efforts. But it could have done a much better job of comparing such efforts and their likely impact to programs designed to increase the supply of tissue matched organs and to suppress rejection of donor organs. The article makes clear that the only way for patients to receive the experimental therapy at present is through a clinical trial, although it does not say where such trials are taking place or recruiting patients. The article makes it clear that this treatment is novel, but could have been much strengthened if it had explained more of the biology of the enzyme and the way it was developed. One of the experts quoted was clearly astonished enough at the effects of the enzyme that he would consider it a "game changer" if further studies verify its impact. But just why the enzyme works is not clearly explained. Hansa Medical issued a news release pursuant to publication of the study results in the New England Journal of Medicine, but the story clearly goes beyond the release.
