Jun 4: A malaria drug President Donald Trump took to try to prevent COVID-19 proved ineffective for that in the first large, high-quality study to test it in people in close contact with someone with the disease.

Results published Wednesday by the New England Journal of Medicine show that hydroxychloroquine was no better than placebo pills at preventing illness from the coronavirus.

The drug did not seem to cause serious harm, though -- about 40% on it had side effects, mostly mild stomach problems.

 “We were disappointed. We would have liked for this to work,” said the study leader, Dr. David Boulware, an infectious disease specialist at the University of Minnesota.

“But our objective was to answer the question and to conduct a high-quality study,” because the evidence on the drug so far has been inconclusive, he said.

Hydroxychloroquine and a similar drug, chloroquine, have been the subject of much debate since Trump started promoting them in March.

Hydroxychloroquine has long been used for malaria, lupus, and rheumatoid arthritis, but no large studies have shown it or chloroquine to be safe or effective for much sicker patients with coronavirus, and some studies have suggested the drugs may do harm.

Trump took a two-week course of hydroxychloroquine, along with zinc and Vitamin D, after two staffers tested positive for COVID-19, and had no ill effects, according to results of his latest physical released by his doctor Wednesday.

Federal regulators have warned against hydroxychloroquine's use except in hospitals and formal studies because of the risk of side effects, especially heart rhythm problems.

Boulware's study involved 821 people in the United States and Canada living with someone diagnosed with COVID-19 or at high risk of getting it because of their job -- doctors, nurses, ambulance workers who had significant exposure to a sick patient while not wearing full protective gear.

They were randomly assigned to get either the nutrient folate as a placebo or hydroxychloroquine for five days, starting within four days of their exposure. Neither they nor others involved in the research knew who was getting which pills.

After 14 days in the study, 12 per cent on the drug developed COVID-19 symptoms versus 14 per cent in the placebo group, but the difference is so small it could have occurred by chance, Boulware said.

“There's basically no effect. It does not prevent infection,” he said of the drug. Even if it were to give some slim advantage, “we'd want a much larger effect” to justify its use and risk of side effects for preventing illness, he said.

Results were no different among a subgroup of participants who were taking zinc or vitamin C, which some people believe might help make hydroxychloroquine more effective or fight the coronavirus.

There are some big caveats: The study enrolled people through the Internet and social media, relying on them to report their own symptoms rather than having them tracked in a formal way by doctors.

Participants were not all tested for the coronavirus but were diagnosed as COVID-19 cases based on symptoms in many cases. And not all took their medicines as directed.

The results “are more provocative than definitive,” and the drug may yet have prevention benefits if tried sooner or in a different way, Dr. Myron Cohen of the University of North Carolina at Chapel Hill wrote in a commentary in the journal.

Others were glad to see a study that had a comparison group and good scientific methods after so many weaker reports on hydroxychloroquine.

“This fits with everything else we've seen so far which suggests that it's not beneficial," said Dr. Peter Bach, director of a health policy center at Memorial Sloan Kettering Cancer Center in New York.

This study was in younger relatively healthy people, but the results “would make me very discouraged about trying to use this in older people” who are most vulnerable to serious illness from the coronavirus, Bach said.

“If it does work, it doesn't work very well.” Dr. Dan Culver, a lung specialist at the Cleveland Clinic, said there's still a chance that giving the drug sooner than four days after someone's exposure to the virus may help prevent illness.

But the study “takes 'home run' off the table” as far as hopes for the drug, he said.

The study was mostly funded by David Baszucki, founder of Roblox, a California-based game software company, and other private donors and the Minnesota university.

Boulware also is leading a study testing hydroxychloroquine for treating COVID-19. The study is finished and results are being analyzed now.

On Tuesday, the journal Lancet posted an “expression of concern” about a study it published earlier this month of nearly 15,000 COVID-19 patients on the malaria drugs that tied their use to a higher risk of dying in the hospital or developing a heartbeat problem.

Scientists have raised serious questions about the database used for that study, and its authors have launched an independent audit.

That work had a big impact: the World Health Organization suspended use of hydroxychloroquine in a study it is leading, and French officials stopped the drug's use in hospitals. On Wednesday, the WHO said experts who reviewed safety information decided that its study could resume.

Bueno Aires, Apr 25: Dozens of prisoners at a jail in Argentina's capital Buenos Aires rioted on Friday demanding urgent health measures after confirmation of a coronavirus case inside the facility.

Police surrounded the prison, which holds around 2,200 inmates, as explosions were heard, news agency reporters at the scene said.

A group of prisoners managed to climb onto a roof, burn mattresses and throw objects at security guards trying to quell the uprising.

Authorities have yet to comment on the riot or whether there are any injuries.

Inmates could be heard shouting demands for a judge to hear their case and for better protection against the pandemic, just a few days after a warden at the Villa Devoto prison was confirmed to have contracted the novel coronavirus.

"COVID-19 in Devoto, genocidal judges," read a banner hung from the prison roof. "We refuse to die in prison," read another.

The inmates are demanding, among other things, that releases that were pending before the pandemic be processed.

Several other riots broke out in prisons last week, including in Florencio Varela in Buenos Aires province where one inmate died and 20 were injured.

Argentina has been in lockdown since March 20 and has recorded more than 3,400 coronavirus cases and 167 deaths.

Moscow, Jul 2: Russian voters approved changes to the constitution that will allow President Vladimir Putin to hold power until 2036, but the weeklong plebiscite that concluded Wednesday was tarnished by widespread reports of pressure on voters and other irregularities.

With most of the nation's polls closed and 20% of precincts counted, 72% voted for the constitutional amendments, according to election officials.

For the first time in Russia, polls were kept open for a week to bolster turnout without increasing crowds casting ballots amid the coronavirus pandemic a provision that Kremlin critics denounced as an extra tool to manipulate the outcome.

A massive propaganda campaign and the opposition's failure to mount a coordinated challenge helped Putin get the result he wanted, but the plebiscite could end up eroding his position because of the unconventional methods used to boost participation and the dubious legal basis for the balloting.

By the time polls closed in Moscow and most other parts of Western Russia, the overall turnout was at 65%, according to election officials. In some regions, almost 90% of eligible voters cast ballots.

On Russia's easternmost Chukchi Peninsula, nine hours ahead of Moscow, officials quickly announced full preliminary results showing 80% of voters supported the amendments, and in other parts of the Far East, they said over 70% of voters backed the changes.

Kremlin critics and independent election observers questioned the turnout figures.

We look at neighboring regions, and anomalies are obvious there are regions where the turnout is artificially (boosted), there are regions where it is more or less real, Grigory Melkonyants, co-chair of the independent election monitoring group Golos, told The Associated Press.

Putin voted at a Moscow polling station, dutifully showing his passport to the election worker. His face was uncovered, unlike most of the other voters who were offered free masks at the entrance.

The vote completes a convoluted saga that began in January, when Putin first proposed the constitutional changes.

He offered to broaden the powers of parliament and redistribute authority among the branches of government, stoking speculation he might seek to become parliamentary speaker or chairman of the State Council when his presidential term ends in 2024.

His intentions became clear only hours before a vote in parliament, when legislator Valentina Tereshkova, a Soviet-era cosmonaut who was the first woman in space in 1963, proposed letting him run two more times.

The amendments, which also emphasize the primacy of Russian law over international norms, outlaw same-sex marriages and mention a belief in God as a core value, were quickly passed by the Kremlin-controlled legislature.

Putin, who has been in power for more than two decades longer than any other Kremlin leader since Soviet dictator Josef Stalin said he would decide later whether to run again in 2024.

He argued that resetting the term count was necessary to keep his lieutenants focused on their work instead of darting their eyes in search for possible successors.

Analyst Gleb Pavlovsky, a former Kremlin political consultant, said Putin's push to hold the vote despite the fact that Russia has thousands of new coronavirus infections each day reflected his potential vulnerabilities.

Putin lacks confidence in his inner circle and he's worried about the future, Pavlovsky said.

He wants an irrefutable proof of public support.

Even though the parliament's approval was enough to make it law, the 67-year-old Russian president put his constitutional plan to voters to showcase his broad support and add a democratic veneer to the changes.

But then the coronavirus pandemic engulfed Russia, forcing him to postpone the April 22 plebiscite.

The delay made Putin's campaign blitz lose momentum and left his constitutional reform plan hanging as the damage from the virus mounted and public discontent grew.

Plummeting incomes and rising unemployment during the outbreak have dented his approval ratings, which sank to 59%, the lowest level since he came to power, according to the Levada Center, Russia's top independent pollster.

Moscow-based political analyst Ekaterina Schulmann said the Kremlin had faced a difficult dilemma: Holding the vote sooner would have brought accusations of jeopardizing public health for political ends, while delaying it raised the risks of defeat.

Holding it in the autumn would have been too risky, she said.

In Moscow, several activists briefly lay on Red Square, forming the number 2036 with their bodies in protest before police stopped them.

Some others in Moscow and St. Petersburg staged one-person pickets and police didn't intervene.

Several hundred opposition supporters rallied in central Moscow to protest the changes, defying a ban on public gatherings imposed for the coronavirus outbreak. Police didn't intervene and even handed masks to the participants.

Authorities mounted a sweeping effort to persuade teachers, doctors, workers at public sector enterprises and others who are paid by the state to cast ballots. Reports surfaced from across the vast country of managers coercing people to vote.

The Kremlin has used other tactics to boost turnout and support for the amendments.
