Modi govt slams UN for opposing its decision to deport helpless Rohingyas

Singapore, May 6: Oil prices slipped back Wednesday after two days of gains, although Brent crude remained above $30 a barrel, as renewed US-China tensions offset optimism about the easing of coronavirus lockdowns.

Brent, the international benchmark, fell 1.1 per cent to $30.63 a barrel in early Asian trade. On Tuesday, the contract surged 14 per cent and rose above $30 for the first time since mid-April.

US marker West Texas Intermediate slipped 1.9 per cent and was changing hands for $24.13 a barrel.

Oil markets have been battered as the virus strangled demand due to business closures and travel restrictions, with US crude falling into negative territory last month for the first time.

They started rallying strongly this week as countries from Europe to Asia ease curbs and economies start shuddering back to life.

But gains were capped Wednesday as dealers follow a brewing US-China row after Donald Trump hit out at Beijing over its handling of the outbreak, saying it began in a Wuhan lab, but so far offering no evidence.

"Traders are incredibly cautious this morning, weighing all the possible China responses," said Stephen Innes, chief global market strategist at AxiCorp.

"And the one that would hurt the most would be for China to reduce imports of US oil."

This week's rally was in part driven by a deal agreed between top producers to reduce output by almost 10 million barrels a day, which came into effect on May 1.

There have also been signs that the massive oversupply in the market is starting to ease as demand slowly comes back.

Energy data provider Genscape said earlier this week that stockpiles at the main US oil depot in Cushing, Oklahoma had increased by only 1.8 million barrels last week following weeks of major rises.

Washington, Apr 28: After nearly three weeks in an intensive care unit in Los Angeles, doctors treating 41-year-old Broadway actor Nick Cordero for COVID-19 were forced to amputate his right leg.

The flow of blood had been impeded by a blood clot: yet another dangerous complication of the disease that has been bubbling up in frontline reports from China, Europe and the United States.

To be sure, so-called "thrombotic events" occur for a variety of reasons among intensive care patients, but the rates among COVID-19 patients are far higher than would be otherwise expected.

"I have had 40-year-olds in my ICU who have clots in their fingers that look like they'll lose the finger, but there's no other reason to lose the finger than the virus," Shari Brosnahan, a critical care doctor at NYU Langone said.

One of these patients is suffering from a lack of blood flow to both feet and both hands, and she predicts an amputation may be necessary, or the blood vessels may get so damaged that an extremity could drop off by itself.

Blood clots aren't just dangerous for our limbs, but can make their way to the lungs, heart or brain, where they may cause lethal pulmonary embolisms, heart attacks, and strokes.

A recent paper from the Netherlands in the journal Thrombosis Research found that 31 percent of 184 patients suffered thrombotic complications, a figure that the researchers called "remarkably high" -- even if extreme consequences like amputation are rare.

Behnood Bikdeli, a doctor at New York-Presbyterian Hospital, assembled an international consortium of experts to study the issue. Their findings were published in the Journal of The American College of Cardiology.

The experts found the risks were so great that COVID-19 patients "may need to receive blood thinners, preventively, prophylactically," even before imaging tests are ordered, said Bikdeli.

What exactly is causing it? The reasons aren't fully understood, but he offered several possible explanations.

People with severe forms of COVID-19 often have underlying medical conditions like heart or lung disease -- which are themselves linked to higher rates of clotting.

Next, being in intensive care makes a person likelier to develop a clot because they are staying still for so long. That's why for example people are encouraged to stretch and move around on long haul flights.

It's also now clear the COVID-19 illness is associated with an abnormal immune reaction called "cytokine storm" -- and some research has indicated this too is linked to higher rates of clotting.

There could also be something about the virus itself that is causing coagulation, which has some precedent in other viral illnesses.

A paper in the journal The Lancet last week showed that the virus can infect the inner cell layer of organs and of blood vessels, called the endothelium. This, in theory, could interfere with the clotting process.

According to Brosnahan, while thinners like Heparin are effective in some patients, they don't work for all patients because the clots are at times too small.

"There are too many microclots," she said. "We're not sure exactly where they are."

Autopsies have in fact shown some people's lungs filled with hundreds of microclots.

The arrival of a new mystery however helps solve a slightly older one.

Cecilia Mirant-Borde, an intensive care doctor at a military veterans hospital in Manhattan, told AFP that lungs filled with microclots helped explain why ventilators work poorly for patients with low blood oxygen.

Earlier in the pandemic doctors were treating these patients according to protocols developed for acute respiratory distress syndrome, sometimes known as "wet lung."

But in some cases, "it's not because the lungs are occupied with water" -- rather, it's that the microclotting is blocking circulation and blood is leaving the lungs with less oxygen than it should.

It has just been a little under five months since the virus emerged in Wuhan, China, and researchers are learning more about its impact every day.

"While we react surprised, we shouldn't be as surprised as we were. Viruses tend to do weird things," said Brosnahan.

While the dizzying array of complications may seem daunting, "it's possible there'll be one or a couple of unifying mechanisms that describe how this damage happens," she said.

"It's possible it's all the same thing, and that there'll be the same solution."

New Delhi, Jul 20: India's COVID-19 case tally crossed the 11 lakh mark with the highest single-day spike of 40,425 new cases and 681 deaths reported in the last 24 hours, informed the Union Health and Family Welfare Ministry on Monday.

Total cases in the country now stand at 11,18,043 while the death toll is 27,497.
The Health Ministry said the total number of cases includes 3,90,459 active cases and 7,00,087 patients have been cured/discharged/migrated.

Maharashtra remains the worst affected state with 3,10,455 cases reported until Sunday.
Meanwhile, as per the information provided by the Indian Council of Medical Research (ICMR), 1,40,47,908 samples have been tested for COVID-19 till July 19, of these 2,56,039 samples were tested yesterday.
