Experts carve out path to fight tuberculosis in China

As one of the oldest infectious diseases, tuberculosis (TB) has plagued the world for centuries. Yet despite growing awareness and a stronger resolve to stamp it out, the disease continues to be relentless. In China, while the fight against TB still faces many challenges, experts say they have identified them and believe real progress will soon be made.

TB is not only the 13th most common cause of death in the world but also the second deadliest infectious disease. In the face of the devastating health consequences, the World Health Organization (WHO) has proposed a strategy to end TB by 2035, an effort in concert with the United Nations Sustainable Development Goals (SDGs) which have also included targets to combat the disease. However, experts say it remains highly difficult to reach these goals.

“The progress made to reach these goals is far from satisfactory,” Tang Shenglan, a professor from Duke University School of Medicine, said at a virtual seminar on Monday.

The SDGs call for a 90 percent reduction in TB deaths and an 80 percent reduction in tuberculosis incidence rate by 2030, compared to the 2015 baseline, as well as the complete eradication of catastrophic expenditures by TB-affected families. But as of 2019, 49 percent of the world’s TB patients still faced catastrophic costs, and while that was an improvement, there is still a long way to go, Tang said.

He pointed out that the COVID-19 pandemic has cast a deeper shadow over the goal of ending TB, with the patient detection rate falling and treatment being forcibly interrupted.

According to a 2019 estimate by the WHO, about 66,000 TB patients who were resistant to rifampicin, an antibiotic, were detected in China, ranking the country second in the world. As drug resistance means longer treatment periods, higher treatment costs and greater difficulties in curing the disease, China is considered one of the high-burden countries, with over 19 percent of TB patients facing catastrophic expenditures.

Mao Zongfu, a professor at Wuhan University School of Public Health and director of the Wuhan University Global Health Research Center, attributed the situation in China to four factors: developing countries with large populations are more likely to be high-burden; China’s tiered fiscal and taxation system has led to an uneven distribution of funds designed to fight the disease; the three-tiered public health system is fragmented and riddle with competition, which leads to perverse incentives in the health care sector; valid vaccines are lacking and motivation for innovation is insufficient.

As a high-burden country, China has committed a great deal of efforts and resources to TB prevention and control. Tang said over 90 percent of the country’s population, including most TB patients, is covered by basic health insurance.

Basic health insurance also treats TB patients more preferably, with the reimbursement ratio reaching 60-70 percent or higher for multidrug-resistant patients.

At the state level, the government has introduced policies to further ally patients’ financial strains, including expanding the scope of health insurance coverage and centralizing the effort to purchase drugs, according to Mao, who also attended Monday’s seminar.

Local governments have also worked out their paths to tackle the disease, he said. In Ningxia Hui Autonomous Region, for example, all cities and counties are required to designate a certain amount of local fiscal budgets to combat TB.

But problems still remain, and the goal of eradicating high treatment costs still faces many challenges.

Under China’s current model, the responsibility of preventing, treating and controlling TB all lies in designated hospitals. But an profit-oriented approach by some hospitals may lower their incentive in disease prevention, said Chen Jiaying, director of the Department of Humanities and Management at Nanjing Medical University.

Health insurance has played a limited role in incentivizing medical facilities to regulate their conduct, and overcharging for redundant services is seen among them, Chen said, adding that there is a greater need to infuse health insurance with that role.

TB prevention is the most economical means to fight the disease, and that’s why it is imperative to raise public awareness, Mao said.

Other than that, he said supervision on health insurance funds and the quality of clinical care should be strengthened, a public health system that caters more to TB patients should be established, and the drug purchasing model should be innovated to lower the prices of anti-TB medicines.

Google trial wraps up as judge weighs landmark U.S. antitrust claims

FI

Published

By

Google and the U.S. Justice Department wrapped up closing arguments on Friday over claims that the Alphabet unit has unlawfully dominated web search and related advertising, in a case the government contends could shape the “future of the internet.”

U.S. District Judge Amit Mehta in Washington for hours grilled both sides with questions, probing whether competitive platforms such as ByteDance’s TikTok and Meta’s Facebook and Instagram are competitive substitutes for search advertising dollars.

Mehta said a central issue was platform “substitute-ability” for advertisers, which the court must resolve. He will now begin preparing to render a major decision on whether Google’s conduct broke civil antitrust law. He did not indicate when he would rule, but experts say he could potentially order changes to Google’s business practices.

Mehta also questioned whether Google assesses competitors’ pricing while considering its own adjustments. Google’s advertising business is responsible for about three-quarters of its revenue.

U.S. government lawyer David Dahlquist argued that “advertising revenue is what drives Google’s monopoly power today.”

Google has boasted it feels no real market pressures, Dahlquist said, arguing that the company does not fear increasing its pricing or not improving its products.

“Only a monopolist can make a product worse and still make more money,” Dahlquist argued.

Google’s lawyer John Schmidtlein countered that Google’s share of U.S. digital advertising revenue has steadily decreased. He touted the advertising power of rival platforms ByteDance’s TikTok, Meta’s Facebook and Instagram, and Amazon.

That’s because it’s not made from plastic, but wheat straw and has seeds nestled inside.

Schmidtlein argued that Google is “constrained” by rival platforms “where the eyeballs are,” because advertisers know there are overlapping audiences and can spend their dollars elsewhere.

He also asserted that Google was continually moving to innovate its search advertising products. “If Google is a monopolist, why improve anything? Why not just jack the price up?” he told the court. He later argued that “Google has won with a superior product.”

The Justice Department has hammered away at Google in a trial that started on September 12, contending the search engine giant is a monopolist that illegally abused its power to boost profits.

Witnesses from Verizon, Android maker Samsung Electronics and Google itself testified about the company’s annual payments, $26.3 billion in 2021, to ensure that its search is the default on smartphones and browsers, and to keep its dominant market share.

Mehta also took up the government’s claim that Google intentionally destroyed internal documents that were relevant to the issues in the lawsuit.

The government asked Mehta to presume that Google deleted chats that were unfavorable to the company.

Mehta repeatedly questioned Google’s prior policies, which he said left document retention decisions to its employees.

“They should have been preserved. Should there be some consequence for what at a minimum was far from best practices?” the judge asked.

A lawyer for Google, Colette Connor, defended its data preservation practices, calling them reasonable, and urged the court not to sanction the company.

The case, filed by former U.S. President Donald Trump’s administration, was the first of several aimed at reining in the market power of tech leaders.

Another case, against Facebook parent Meta, was also filed during the Trump administration. U.S. President Joe Biden’s antitrust enforcers have followed with a second case against Google and cases against Amazon.com and Apple Inc.

UN adopts first global artificial intelligence resolution to ensure AI is safe

The United Nations General Assembly unanimously adopted the first global resolution on artificial intelligence on Thursday, encouraging countries to safeguard human rights, protect personal data, and monitor AI for risks.

The nonbinding resolution, proposed by the United States and co-sponsored by China along with over 120 other nations, also advocates for the strengthening of privacy policies.

“Today, all 193 members of the United Nations General Assembly have spoken in one voice, and together, chosen to govern artificial intelligence rather than let it govern us,” U.S. Ambassador to the United Nations Linda Thomas-Greenfield said.

The resolution is the latest in a series of initiatives – few of which carry significant enforceability – by governments around the world to shape AI’s development amid fears it could disrupt democratic processes, turbocharge fraud, or lead to dramatic job losses, among other harms.

“The improper or malicious design, development, deployment and use of artificial intelligence systems … pose risks that could … undercut the protection, promotion and enjoyment of human rights and fundamental freedoms,” the measure states.

In November, the U.S., Britain and more than a dozen other countries unveiled the first detailed international agreement on how to keep artificial intelligence safe from rogue actors, pushing for companies to create AI systems that are “secure by design.”

Europe is ahead of the United States, with EU lawmakers adopting a provisional agreement this month to oversee the technology. The Biden administration has been pressing lawmakers for AI regulation, but a polarized U.S. Congress has made little headway. In the meantime, the White House sought to reduce AI risks to consumers, workers, and minorities while also bolstering national security with a new executive order in October.

The resolution aims to close the digital divide between rich developed countries and poorer developing countries to ensure that all are included in discussions on AI. It also aims to ensure that developing countries have the technology and capabilities to take advantage of AI’s benefits, including detecting diseases, predicting floods, helping farmers, and training the next generation of workers.

The resolution recognizes the rapid acceleration of AI development and use and stresses “the urgency of achieving global consensus on safe, secure and trustworthy artificial intelligence systems.”

It also acknowledges that “the governance of artificial intelligence systems is an evolving area” that requires further discussions on possible governance approaches and emphasizes that innovation and regulation are mutually reinforcing – not mutually exclusive.
