Example Input: Paragraph: Repeated attacks on treatment centers by armed militiamen and community members who think Ebola is a conspiracy against them have hampered the response to the second-deadliest outbreak of the hemorrhagic fever in history. In the latest attack, on a hospital in the city of Butembo, a senior World Health Organization (WHO) epidemiologist from Cameroon was killed and two others wounded last Friday. At a protest on Wednesday in Butembo, the biggest city to be affected by the current outbreak, dozens of Congolese doctors and nurses marched behind a banner reading “Ebola exists” and urged authorities to take additional security measures. “If our security is not guaranteed, we will go on strike from the first week of May,” Dr. Kalima Nzanzu said, reading from a memo to Butembo’s mayor, Sylvain Kanyamanda. Kanyamanda told Reuters that he understood the health workers’ frustrations and that the government was determined to respond to their demands. The latest outbreak of Ebola, which was declared last August and is Congo’s tenth since the virus was discovered in 1976, is believed to have killed 880 people and infected nearly 500 more in North Kivu and Ituri provinces. The military prosecutor’s office in North Kivu said on Wednesday that authorities had captured the suspected ringleader of last week’s attack, as well as about a dozen other suspects. Prosecutors believe the assailants belong to an armed group called the Patriotic Union for the Liberation of Congo (UPLC) based on a tract left at the hospital threatening health workers. Dozens of militia are active in eastern Congo’s borderlands with Rwanda, Uganda and Burundi, where they run lucrative rackets and fight over land, ethnicity and mineral resources. Claim: Ebola first responders threaten strike if security not improved.
Example Output: Health workers in one of the epicenters of eastern Democratic Republic of Congo’s Ebola outbreak threatened on Wednesday to go on strike as early as next week if authorities don’t do more to protect them.

Example Input: Paragraph: Pfizer shares were up nearly 4 percent on positive findings for the oral treatment, called palbociclib, one of the company’s most important experimental drugs that some analysts believe could eventually claim annual sales of more than $5 billion, if approved. The trial tested the pill in post-menopausal patients with locally advanced or newly diagnosed breast cancer that had spread to other parts of the body. “We are delighted with the final data,” Pfizer said in a release, adding the company will discuss the successful data on progression-free survival with the U.S. Food and Drug Administration “to determine next steps” for palbociclib. A secondary goal of the study is to determine whether palbociclib can prolong overall survival. But Pfizer spokeswoman Sally Beatty said the company does not yet have such data, because it takes longer periods to follow patients and gauge survival trends. Although Pfizer is conducting two larger late-stage trials of palbociclib, ISI Group analyst Mark Schoenebaum noted the company has previously said it might discuss with the FDA the potential to seek approval of the medicine based upon mid-stage trial data, if the data warranted. Palbociclib, which blocks enzymes known as cyclin-dependent kinases (CDKs) 4 and 6, was taken in combination with a standard treatment called letrozole among women who were estrogen receptor positive - meaning tumors grow in response to estrogen - and HER2-negative, meaning that the HER2 protein is not causing the cancer. Such patients make up about 60 percent of advanced breast cancer cases. Letrozole is the chemical name of Femara, a Novartis AG drug that belongs to a class of treatments called aromatase inhibitors that block production of estrogen. Pfizer on Monday did not present detailed data from the trial results, saying they would be presented at a scientific meeting in San Diego in April. The success of the trial, called Paloma-1, follows highly favorable interim data that Pfizer unveiled in December 2012. At that point in the study, those taking both palbociclib and letrozole went an average of 26.1 months before tumors worsened. That compared with 7.5 months for those taking letrozole, but not palbociclib. The 18.6-month difference was considered statistically significant. Side effects from palbociclib were similar to those previously reported, Pfizer said on Monday. The earlier interim results had shown that patients taking the drug combination experienced anemia, fatigue and neutropenia - a decline in white blood cells called neutrophils that can put patients at higher risk of infection. Palbociclib was designated a “breakthrough” drug by the FDA last April based on initial data from the trial. The FDA grants “breakthrough” status to drugs that may offer substantial improvement over existing treatments for serious or life-threatening diseases. The status helps to speed up the approval process. Pfizer has started two late-stage trials of the drug - Paloma-2 and Paloma-3 - in patients with advanced breast cancer. Paloma-2 will test the same drug combination, palbociclib and letrozole, as an initial treatment for breast cancer. Paloma-3 will evaluate palbociclib in combination with another hormone therapy, fulvestrant, in women whose cancer has progressed after hormonal therapy. The drug, sold under the brand name Faslodex by AstraZeneca Plc, is called an estrogen receptor antagonist. Companies trying to develop treatments similar to palbociclib include Novartis and Eli Lilly & Co. Breast cancer killed more than 508,000 women worldwide in 2011, according to the World Health Organization. Pfizer shares were up 3.7 percent at $31.53 on Monday morning on the New York Stock Exchange. Claim: Pfizer breast cancer drug succeeds in mid-stage trial.
Example Output: Pfizer Inc’s experimental breast cancer drug significantly delayed progression of symptoms in a mid-stage trial, meeting the study’s primary goal and keeping Pfizer in the forefront of a race for a new standard of care for the disease.

Example Input: Paragraph: Robert Mardini, the ICRC’s U.N. observer, told journalists that while there has been a de-escalation of fighting in Yemen which is positive news, the Arab world’s poorest nation faces “a very dire humanitarian situation.” It is not only facing an escalation in dengue cases but must also continue to deal with tens of thousands of cholera cases as well as malaria, he said. More than 3,500 cases of dengue have been reported in Taiz, Mardini said. And in Hodeida, where the country’s main port is located, the ICRC heard that 50 people died in late October and early November of dengue fever and malaria, and the local head office reported the number of people infected with dengue fever is 2,000, and close to 3,000 have malaria. “So you can imagine, with the violence and the fighting, it is a big challenge to control this epidemic,” Mardini said. In addition, he said, last year’s “spectacular” cholera epidemic in Yemen isn’t over yet, pointing to more than 56,000 cases reported between January and September. The European Commission’s humanitarian aid operation known as ECHO reported Monday that 10 people died of dengue fever in Taiz governorate last week and local health authorities expected the death toll to increase. As of Thursday, ECHO said, 7,970 cases of dengue fever were reported in the governorate. It said 3,215 were confirmed and 103 patients were under observation in government hospitals. Dengue fever is a painful, debilitating disease caused by viruses transmitted by mosquitoes that breed in stagnant water. Malaria is caused by a parasite also transmitted by mosquitoes, and cholera is caused by eating food or drinking water contaminated by bacteria. Mardini said dengue and malaria are endemic in Yemen though in recent years their prevalence had “been extremely low.” But now, because of the weakness of the country’s health system and problems with its water supplies and sanitation, malaria and dengue are appearing again, he said. The conflict in Yemen began with the 2014 takeover of the capital, Sanaa, by Iranian-backed Houthis who control much of the country’s north. A Saudi-led coalition allied with the internationally recognized government has been fighting the Houthis since 2015. Fighting in Yemen has killed thousands of civilians and created the world’s worst humanitarian crisis, leaving millions suffering from food and medical care shortages and pushing the country to the brink of famine. Claim: Red Cross reports new outbreak of dengue fever in Yemen.
Example Output:
The International Committee of the Red Cross reported a new outbreak of dengue fever in war-torn Yemen on Monday, with thousands of cases reported and several dozen deaths.
