Example Input: In a study in the medical journal The Lancet, they said the patients, with strains of TB known as extensively-drug resistant (XDR) and totally drug resistant (TDR) TB, have exhausted all available treatment options and are sent home. “These patients can survive for months or even years and are contributing to the community-based spread of XDR-TB,” said Keertan Dheda, who led the study at the University of Cape Town’s department of medicine. Tuberculosis infects the lungs and can spread through coughing and sneezing. In recent years, drug-resistant strains have spread around the world, batting off standard antibiotics and posing an increasingly urgent public health threat. The World Health Organization (WHO) estimates that in Eastern Europe, Asia and South Africa, 450,000 people have MDR-TB, and around half of these will fail to respond to existing treatments. Dheda’s team followed 107 patients with XDR-TB from three provinces in South Africa between March 2008 and August 2012 to establish their fate. They also took samples from 56 patients and tested them to find out which and how many of 10 first- and second-line anti-TB drugs they were susceptible to. Despite being treated intensively with an average of eight anti-tuberculosis drugs, many of the patients fared poorly, with high rates of treatment failure and death. Five years after treatment initiation, only 12 of the patients had favorable outcomes and 74 percent had died. The researchers found that almost two-thirds of the tested patients had resistance to at least eight drugs, and there was one case of totally drug-resistant TB that was not susceptible to any of the 10 drugs tested. More worrisome, Dheda said, was that of the XDR-TB patients discharged into the general community, some 42 percent had failed to get better on treatment and were testing positive for active TB, and of these almost a third were at high risk of transmitting the disease. The patients also survived in the community for an average of 20 months - plenty of time to infect others. When people with lung TB cough, sneeze or spit, they propel the TB germs into the air. Another person needs to inhale only a few of these germs to become infected. “Alarmingly, we have shown for the first time that... treatment failure and discharge of such patients into the wider community is occurring systematically on a country-wide level in South Africa,” Dheda said in a statement about the findings. In one case where the researchers followed a genetic trail of transmission, they found that a patient with XDR-TB who was discharged after failing treatment went on to infect his brother, who also eventually died. Dheda said the reason many TB patients are being sent away from hospitals appeared to be lack of bed space in designated tuberculosis hospitals. “And alternative long-term residential and palliative care facilities are scarce.”  Commenting on the findings in The Lancet, Max O’Donnell from New York’s Albert Einstein College of Medicine in the United States said they should serve as an “urgent alarm”. “MDR-TB (multi-drug-resistant TB) in all its forms is an out-of-control problem with potentially vast and devastating consequences for global public health,” he wrote. “The situation regarding MDR and XDR-TB is bleak.”
Example Output: South Africa risks spreading totally drug-resistant TB: study.

Example Input: Scientists said on Wednesday many Tibetans possess a rare variant of a gene involved in carrying oxygen in the blood that they likely inherited from an enigmatic group of extinct humans who interbred with our species tens of thousands of years ago. It enables Tibetans to function well in low oxygen levels at elevations upwards of 15,000 feet (4,500 meters) like the vast high plateau of southwestern China. People without this variant would be apt to develop thick blood, leading to high blood pressure, heart attacks, strokes, low-birth-weight babies and higher infant mortality. This version of the EPAS1 gene is nearly identical to one found in Denisovans, a lineage related to Neanderthals - but is very different from other people today. Denisovans are known from a single finger bone and two teeth found in a Siberian cave. DNA testing on the 41,000-year-old bone indicated Denisovans were distinct from our species and Neanderthals. “Our finding may suggest that the exchange of genes through mating with extinct species may be more important in human evolution than previously thought,” said Rasmus Nielsen, a computational biology professor at the University of California, Berkeley and the University of Copenhagen, whose study appears in the journal Nature. Our genome contains residual genetic fragments from other organisms like viruses as well as species like Neanderthals with which early modern humans interbred. The researchers called their study the first to show that a gene from an archaic human species has helped modern humans adjust to different living conditions. “Such exchange of genes with other species may in fact have helped humans adapt to new environments encountered as they spread out of Africa and into the rest of the world,” said  Nielsen. Asan Ciren, a researcher with China’s BGI genomics center, added, “The genetic relationship or blood relationship between modern humans and archaic hominins is a hot topic of the current paleoanthropology.”  The researchers said early modern humans trekking out of Africa interbred with Denisovans in Eurasia en route to China. Their descendants harbor a tiny percentage of Denisovan DNA. Genetic studies show nearly 90 percent of Tibetans have the high-altitude gene variant, along with a small percentage of Han Chinese, who share a common ancestor with Tibetans. It is seen in no other people. The researchers conducted genetic studies on 40 Tibetans and 40 Han Chinese and performed a statistical analysis showing that the gene variant almost certainly was inherited from the Denisovans. The gene regulates production of hemoglobin, a protein in red blood cells that carries oxygen. It is turned on when blood oxygen levels drop, stimulating more hemoglobin production. At elevations above 13,000 feet (4,000 meters), the common form of the gene boosts hemoglobin and red blood cell production, causing dangerous side effects. The Tibetans’ variant increases hemoglobin and red blood cell levels only modestly, sparing them these effects.
Example Output: Gene from extinct human species fortifies high-altitude Tibetans.

Example Input: Amid mounting global concern over the public health implications of so-called e-cigarettes, Touraine said they faced the same fate as traditional ones: a ban on smoking in public spaces and sales to minors and a blackout on media advertising. In a country where the pungent waft of Gaulloises and Gitanes once seemed an unassailable part of cafe culture, smokers have long been banished to outdoor terrace seats. The near-odorless electronic alternative - battery-driven devices that allow users inhale odorless nicotine-laced vapor rather than smoke - are gaining ground in no-go zones such as bars, cafes, trains, waiting rooms and offices. A government-commissioned report said this week that around 500,000 people in France had turned to e-cigarettes, which are designed to look like cigarettes although some come in different colors, and recommended a crackdown on public use. Health officials in many countries say the impact of electronic cigarettes on health needs further study. Another worry they cite is that the electronic alternative will increase the general temptation to smoke, including enticing those who have quit to start again, or that smokers may use them alongside rather than instead of regular cigarettes. “This is no ordinary product because it encourages mimicking and could promote taking up smoking,” said Touraine, who announced her plans at a news conference. In the United States, the number of smokers who have tried out e-cigarettes doubled to one in five in 2011 and the number of all adults trying it doubled too, to 6 percent, according to the U.S. Centers for Disease Control and Prevention. In France, a country of 66 million, the government says tobacco smoking kills some 66,000 people a year and another 5,000 are killed through passive exposure to smoke. The expert in charge of the French report advised against an outright ban on e-cigarettes, however, saying they still seemed safer than tar-laden tobacco. Electronic cigarettes, whose invention is widely credited to a Chinese pharmacist a decade ago, usually comprise disposable cartridges of liquid such as propylene glycol that is easily turned to vapor and can contain artificial flavors alongside concentrated liquid nicotine.
Example Output:
France to ban electronic cigarettes in public.
