[EX Q]: "Liquid chocolate is prepared in the workshop of the ""Felicitas"" chocolate shop in Hornow, south of Berlin, December 2, 2009. REUTERS/Fabrizio Bensch The study, which combined the results of 42 smaller studies and was published in the American Journal of Clinical Nutrition, also found that participants had small improvements in blood vessel function and a dip in their insulin levels. A number of past studies have found that chocolate lovers seem to have lower rates of certain heart risks, such as high blood pressure. "My take-away message would be that if people like dark chocolate, then eating a little in place of other 'treat' foods is fine, and may be beneficial," said study leader Lee Hooper, at Norwich Medical School in the UK. "However, the evidence is not yet good enough to suggest that we should all be doing this." She cautioned that the studies involved were neither large enough nor long enough to show whether eating chocolate has any effect on a person's risk of having a heart attack or stroke. In contrast to past studies, which were largely observational and couldn't prove cause-and-effect that chocolate itself caused the changes the current study focused on clinical trials, where researchers assigned people to eat chocolate or not and then watched for changes in blood pressure, cholesterol and other heart risk factors. Hooper and her team pooled data from 42 small clinical trials involving about 1,300 people and found that chocolate eaters had a few points knocked off their blood pressure readings, along with lower insulin levels and other benefits. Though it's not clear why chocolate has this affect, it's believed to be due to compounds known as flavonoids, which are also present in foods such as nuts, soy, tea and wine. But researchers acknowledged shortcomings in their study, including differences in the people involved in the trials some healthy, some with chronic health problems and different ways of testing chocolate's effects. Some studies used cocoa drinks, some solid chocolate and some cocoa supplements. They also varied in how long people were "treated," though most trials lasted less than six weeks. The biggest question may be whether any benefits would be worth the downside of chocolate. Based on the studies they used, Hooper's team writes, it could take several hundred calories' worth of chocolate to see effects on insulin and blood vessel function and that could mean trouble for your waistline. "From a practical perspective it is premature to advise individuals to consume chocolate or cocoa to decrease their risk of cardiovascular disease," said Alice Lichtenstein, director of the cardiovascular nutrition lab at Tufts University in Boston, who was not part of the study. For now, she added, if you enjoy a little chocolate in your life, you can probably keep doing so. Just don't add it in the hopes of helping your heart."

[EX Q]: The evacuations of workers in Guangzhou followed medical testing that revealed they might have been affected. State Department spokeswoman Heather Nauert said "a number of individuals" had been brought to the U.S. but didn't say how many were affected or evacuated. A previous case in Guangzhou, disclosed last month, prompted the tests. Nauert also said that remaining U.S. government personnel and their families in Guangzhou would also be able to request testing if they "noted concerning symptoms or wanted baseline screening." The incidents have raised fears the unexplained issues that started in Cuba in 2016 have expanded. The U.S. government has deemed those incidents "specific attacks" on American workers but hasn't publicly identified a cause or culprit. Most of the incidents were accompanied by bizarre, unexplained sounds that initially led U.S. investigators to suspect a sonic attack. Symptoms have included dizziness, headaches and an inability to concentrate. The American government worker who previously was removed from China reported "subtle and vague, but abnormal, sensations of sound and pressure," the Guangzhou consulate reported last month Security guards outside the Guangzhou consulate on Thursday told reporters to leave the area and not attempt to talk to consulate staff. Asked about the latest incidents, Chinese Foreign Ministry spokeswoman Hua Chunying said the U.S. had not formally raised the matter with Beijing. "If the U.S. makes formal contact with us, China will continue necessary investigations in an earnest and responsible manner and maintain close communication and cooperation with the U.S.," Hua said at a regularly scheduled news conference. China earlier said it had looked into the case announced last month but came up with no clues about the cause of the symptoms. The New York Times identified the latest American employee evacuated as Mark A. Lenzi, a security engineering officer at the consulate who left Wednesday night with his wife and two children. Lenzi told the Times he resided in the same apartment tower as the officer evacuated in April and suffered in recent months from what he called "neurological symptoms." Lenzi's apartment was in one of several high-rise buildings in The Canton Place featuring restaurants and galleries spaced around a central plaza. Another diplomat who reported symptoms was at a different upscale building near the consulate, the paper said. A U.S. official, who wasn't authorized to discuss the situation publicly and requested anonymity, said the evacuated American government workers were being brought from China for testing to the University of Pennsylvania. That's where doctors have been treating and studying patients previously evacuated from the U.S. Embassy in Havana. The preliminary findings of the medical reports on the 24 personnel affected in Cuba showed they had sensory and memory problems similar to the brain dysfunction seen with concussions. The Penn team said the patients from Cuba experienced persistent disability though rehabilitation therapy customized for them seemed to help. Canada in April also ordered families of diplomatic staff in Cuba to return home after mysterious health symptoms were detected in 10 Canadians stationed on the island. Canada said the 10 continued to show unexplained brain symptoms and that "medical information raised concerns for a new type of a possible acquired brain injury." In testimony before the Senate Foreign Relations Committee last month about the first case in China, U.S. Secretary of State Mike Pompeo said China had "said all the right things and have demonstrated their willingness to help us identify the vector which led to this medical incident." The China incidents affect one of the most important of the seven U.S. diplomatic outposts in the country. The Guangzhou consulate opened months after the establishment of diplomatic relations between Beijing and Washington in 1979 and moved to its new purpose-built facility in 2013. It serves four southern provinces with a combined population of more than 204 million and processes more than 1 million visa applications of all types annually. It is also the only U.S. diplomatic installation in China authorized to process immigrant visas and handle adoptions. People working in The Canton Place complex, a few kilometers (miles) from the consulate, said they were just hearing about the incidents, reflecting a lack of coverage in China's entirely state-controlled media. Aled Williams, a British teacher at a kindergarten said Thursday that the reports sounded "sci-fi-ish." "Hard to get my head around how it works," he said. "Better watch myself." Linda Chen, who runs a coffee shop in the area, said she was mystified as to why only certain people seemed to have been affected in an area known for its comfort and safety. "For me I feel it's very strange. But I don't feel that there's something to be very afraid of because it's probably a very special case," Chen said. ___ Associated Press writer Josh Lederman in Washington, D.C. contributed to this report.

[EX Q]: Cyclone Idai smashed into Beira on March 14, causing catastrophic flooding and killing more than 700 people across three countries in southeast Africa. Many badly affected areas in Mozambique and Zimbabwe are still inaccessible by road, complicating relief efforts and exacerbating the threat of infection. Although there have been no confirmed cholera deaths in medical centers in Mozambique yet, at least two people died outside hospitals with symptoms including dehydration and diarrhea, the country's environment minister Celso Correia said. A Reuters reporter saw the body of a dead child being brought out of an emergency clinic in Beira on Wednesday. The child had suffered acute diarrhea, which can be a symptom of cholera. "We expected this, we were prepared for this, we've doctors in place," Correia told reporters. The government said for the first time that there had been confirmed cholera cases on Wednesday. Mozambique's National Disaster Management Institute said the local death toll from the tropical storm had increased to 493 people, from 468 previously. That takes the total death toll across Mozambique, Zimbabwe and Malawi to 738 people, with many more still missing. "Stranded communities are relying on heavily polluted water. This, combined with widespread flooding and poor sanitation, creates fertile grounds for disease outbreaks, including cholera," the International Committee of the Red Cross said in a statement. The World Health Organization's Tarik Jasarevic said 900,000 doses of oral cholera vaccine were expected to arrive on Monday. The U.S. Defense Department said on Friday it had authorized an additional $8.5 million in humanitarian assistance for Mozambique, bringing the total to $15 million. About 50 U.S. military personnel have been sent to Mozambique to assist with logistics, including transporting food and medical supplies. Cholera is endemic to Mozambique, which has had regular outbreaks over the past five years. About 2,000 people were infected in the last outbreak, which ended in February 2018, according to the WHO. But the scale of the damage to Beira's water and sanitation infrastructure, coupled with its dense population, have raised fears that another epidemic would be difficult to put down.
