[EX Q]: Paragraph: "Of more than 300 men and women who had the surgery, a third stopped playing sports entirely and 68 who were still active said they didn’t play as well as before, researchers reported in the American Journal of Sports Medicine. The anterior cruciate ligament, or ACL, is the ligament inside the knee that helps keep the joint stable. About 150,000 ACL injuries occur each year in the United States. “Less than 50 percent of the study sample had returned to playing sport at their preinjury level or returned to participating in competitive sport when surveyed at 2 to 7 years after ACL reconstruction surgery,” wrote Clare Ardern at La Trobe University in Victoria, Australia, who led the study. Ardern and her colleagues followed more than 300 men and women for two to seven years. Participants had either played Australian-rules football, basketball, netball or soccer before their surgeries. At 39 months post-surgery, 208 out of the 314 people who had the operation were still playing a sport, the researchers said. Of those 208, 68 said they played at a lower level than before their injury and 140 said they played about the same as before their injury. The remaining 106 participants either were not playing sports or did not complete the entire study. “Although almost all people returned to playing some form of sport, they did not play continuously for many years after their surgery,” Ardern told Reuters Health in an email. She also noted there may be other reasons why people stopped playing sports, such as fear of getting injured again or less confidence in performing. Of the 196 people who played competitive sports before their injury, 91 returned to their competitive sport. “This is a big injury,” said Edward McDevitt, a spokesman for the American Academy of Orthopaedic Surgeons, who was not part of the study. “Many athletes who choose surgery have a long and difficult road to face. If you’re not willing to go through it, then you might be better off just getting a brace.”   He added that while knee surgery does allow people to return to their sport, they couldn’t perform as well as doctors might wish. People who tear the ACL can either opt for physical therapy and surgery or just physical therapy alone. “Some people find that they are able to function well without surgery, provided they have adequate leg strength to support the injured knee,” Ardern said. “Other alternatives may be to avoid sports involving direction changes, jumping and landing or activities that make the knee feel unstable, or use knee braces and supports.”   McDevitt speculates that after surgery, some athletes may not have the same range of motion, preventing them from playing as before. ""I tell my patients, 'I can't make you like before, I'm not God. But I'll do the best I can to restore you back to the way you were,'"" he added.

[EX A]: After knee reconstruction surgery, half of people who played sports both competitively and just for fun don’t perform as well as they used to, according to an Australian study.

[EX Q]: Paragraph: Two people who had travelled from Congo died in Uganda last week, the World Health Organization said. A three-year-old boy who was sent back to Congo after testing positive for the disease died at the weekend, Congo’s health ministry said. At least another 1,411 people have died in Congo since August in the second worst outbreak of the disease on record. “Happy to inform you all that we got clearance from both Uganda National Council for Science and Technology and National Drug Authority to bring in the Therapeutic treatment for #Ebola patients in the country,” Uganda’s Health Minister, Jane Ruth Aceng, said on Twitter. The treatments approved for shipment to Uganda were Mapp Biopharmaceutical’s ZMapp, Regeneron Pharmaceuticals Inc’s REGN-EB3 and Remdesivir, made by Gilead Sciences, said WHO spokesman Tarik Jasarevic. “The protocols for the fourth being submitted. Logistics underway with MSF support for importation of a few courses about 10 each,” he added in an email. The U.N. health agency has said there have so far been no known cases of Ebola spreading between people in Uganda - all recorded patients had travelled in from Congo. Four experimental therapeutic treatments are already being used in Congo, it added. On Friday, a WHO panel decided not to declare an international emergency over Congo’s Ebola outbreak despite its spread to Uganda, saying such a declaration could cause too much economic harm. “Obviously, the crisis is far from over,” Mark Green, the head of the U.S. Agency for International Development (USAID), told a news conference in Nairobi. Health workers and people who came in contact with infected people began receiving a Merck experimental vaccine in Uganda on Saturday. (This story corrects name of drug in 5th paragraph to REGN-EB3, not Regeneron). Claim: Uganda clears three experimental Ebola treatments, watches for spread.
[EX A]: Health workers have got the all-clear to use three experimental Ebola treatments in Uganda, a week after the deadly disease spread over the border from Democratic Republic of Congo, authorities said on Tuesday.

[EX Q]: Paragraph: More than half of all new HIV infections in 2018 were among sex workers, drug users, men who have sex with men, transgender people, prisoners and the sexual partners of these groups, according to a report by UNAIDS. Many of those populations did not get access to infection prevention services, it said. Progress in some countries has been “impressive”, the U.N. body’s report said, but others are seeing rising numbers of HIV infections and AIDS-related deaths. It noted “worrying increases” in new infections in eastern Europe and central Asia, where HIV cases rose by 29%, as well as in the Middle East, North Africa and Latin America. “Ending AIDS is possible if we focus on people not diseases,” said UNAIDS executive director Gunilla Carlsson. She said now was the time to “create road maps for the people and locations being left behind (and) take a human rights-based approach to reaching people most affected by HIV.”  This would need greater political leadership, she said, starting with adequate and well-targeted investment. Global funding for the AIDS fight dropped off significantly in 2018 - by nearly $1 billion - as international donors gave less and domestic investments did not grow fast enough to plug the gap. Around $19 billion was available for the AIDS response in 2018, UNAIDS said - falling $7.2 billion short of the total $26.2 billion it says is needed by 2020. Globally in 2018, some 770,000 people died of AIDS and almost 38 million people were living with the human immunodeficiency virus (HIV) that causes it. HIV cannot be cured but the infection can be kept in check by AIDS drugs known as antiretrovial treatment. Around 23.3 million of the 37.9 million people with HIV worldwide currently get the AIDS drugs they need. Around 1.7 million people were newly infected, the UNAIDS report said, a 16% decline since 2010, driven mostly by steady progress in parts of eastern and southern Africa. South Africa, for example, has cut new HIV infections by more than 40% and AIDS-related deaths by around 40% since 2010. But the report warned there is still a long way to go in many parts of eastern and southern Africa - the regions most affected by HIV. Claim: U.N. wants more urgency in AIDS fight as gains and funding fade.
[EX A]:
The global fight against AIDS is stalling due to lower investment, marginalized communities missing vital health services, and new HIV infections rising in some parts, the United Nations warned on Tuesday.
