Mysterious blood clots are COVID-19's latest lethal surprise

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."

Vienna, Apr 13: Top oil-producing countries agreed on "historic" output cuts to prop up prices hammered by the coronavirus crisis and a Russia-Saudi price war, sending crude prices soaring on Monday.

The US benchmark WTI climbed 7.7 percent to $24.52 a barrel in early Asian trade while Brent was up 5.0 percent at $33.08.

OPEC producers dominated by Saudi Arabia and allies led by Russia thrashed out a compromise deal via videoconference Sunday after Mexico had balked at an earlier agreement struck on Friday.

In the compromise reached Sunday they agreed to a cut of 9.7 million barrels per day from May, according to Mexican Energy Minister Rocio Nahle, down slightly from 10 million barrels a day envisioned earlier.

OPEC Secretary General Mohammad Barkindo called the cuts "historic".

"They are largest in volume and the longest in duration, as they are planned to last for two years," he said.

The agreement between the Vienna-based Organization of the Petroleum Exporting Countries and partners foresees deep output cuts in May and June followed by a gradual reduction in cuts until April 2022.

Barkindo added that the deal "paved the way for a global alliance with the participation of the G20".

Saudi Energy Minister Prince Abdulaziz bin Salman, who chaired the meeting together with his Russian and Algerian counterparts, also confirmed that the discussions "ended with consensus".

The President of United States Donald Trump has said that countries like India and China would have much more coronavirus cases than America if they conduct more tests.

“I say to my people every time we test; you find cases because we do more testing. If we have more cases, if we wanted to do testing in China or in India or other places, I promise you there would be more cases you are doing a fantastic job in getting out the swabs,” the US president said on Friday.

Trump said that the US has carried out 20 million tests while compared to America, Germany is at four million and much talked about South Korea is about three million tests. He made the remarks at Puritan Medical Products in Maine, according to Johns Hopkins Coronavirus Resource Center.

The US has reported nearly 1.9 million cases and over 1,09,000 deaths while the total number of coronavirus cases in India and China stand at 2,36,184 and 84,177 respectively, according to Johns Hopkins Coronavirus Resource Center data.

India has so far conducted over 4 million COVID-19 tests, according to the health ministry.

Trump said, “we will be well over 20 million tests. Remember this, when you test more, you have more cases.”

“Puritan is one of the only manufacturers in the world producing high-quality medical swabs that are crucial for rapid testing. And every swab you make at Puritan is proudly stamped with the beautiful phrase made in the USA,” Trump said.

“Thanks to the testing capacity that you are making possible, our country is reopening and our economy is recovering like nobody would’ve thought possible,” he added.

Trump also spoke about the huge unemployment problem the country is currently facing. He said that the economy is now back on track, referring to the latest monthly employment numbers,.

“We absolutely shattered expectations, and this is the largest monthly jobs increase in American history, think of that; that’s a long time,” Trump said

“I think it’s more than double or about double of what our highest was before so this is the largest monthly job increase in American history. And we’re going to have a phenomenal next year. We’re going to have a tremendous couple of months prior to the election on November 3 very, very important date,” the president said.

Keeping an eye on the November 3 presidential elections, Trump is seeking re-election for his second consecutive term. He is pitted against Democratic presidential nominee Joe Biden who in opinion polls is surging several points of Trump.

“It’s going to be a very important election because the only thing that can screw it up is if you get the wrong president and they raise your taxes, and they open up your borders so that everybody pours into our country,” Trump said.

Trump also vowed to bring the American economy back on track, which has been badly hit by the coronavirus pandemic. He reiterated that his administration has built a strong economy in the last three years.

Describing the fight against coronavirus as the greatest national and industrial mobilisation since the World War II, Trump said that his administration has marshaled the full power of the US government and US industry to defeat the invisible enemy.

“It is indeed an enemy. It came from China, should have been stopped in China. They didn’t do that,” he alleged.

The administration, he said, has delivered over 1.5 billion pieces of personal protective equipment to doctors and nurses on the front lines. We slashed the red tape to speed up the development of vaccines.

“And vaccines are coming along incredibly well, wait till you see, and therapeutics. And we partnered at private sector leaders such as Puritan to build the largest and most advanced testing capacity on the face of the earth, like this one,” the US president said.

The Puritan factory in Maine, he said, quickly ramped up the production to produce nearly 20 million foam-tipped swabs each month.

“Then in April, my administration invoked the Defence Production Act to help you scale up even more. Under a USD 75 million public-private partnership, Puritan will soon double production to 40 million swabs per month,” Trump added.

Singapore, Jul 11: Singapore Prime Minister Lee Hsien Loong has secured a “clear mandate” with his ruling People’s Action Party (PAP) winning 83 of the 93 contested parliamentary seats in the general election held amidst the Covid-19 pandemic, with the Opposition gaining ground by winning a record 10 seats.

The ruling party, in power since independence in 1965, secured 61.24 percent of the total votes cast in the election, down from 69.9 percent in 2015. About 2.6 million Singaporeans voted on Friday.

“We have a clear mandate, but the percentage of the popular vote is not as high as I had hoped for,” 68-year old Lee told a PAP’s post-results press conference on Saturday morning.

The opposition Workers’ Party secured 10 seats and defeated a team in the Group Representation Constituency of Sengkang led by former Minister in the Prime Minister’s Office Ng Chee Meng who is also the Secretary-General of the power National Trades Union Congress (NTUC).

The Prime Minister assured it is “only right” that Workers’ Party’s Indian-origin secretary-general Pritam Singh be “formally designated” as the Leader of the Opposition, and that he will be provided with “appropriate staff support and resources to perform his duties”.

Lee took the results in “these circumstances” as an “endorsement” of the party’s policies and plans as he had called the elections amidst Covid-19 pandemic.

“We’ll take this forward and work with Singapore to realise those plans and solve the problems which we have,” Channel News Asia quoted the premier as saying.

Lee, who leads the PAP as secretary-general, said, “Singaporeans understand what’s at stake and why we must come together to uphold our national interests.”

He pledged to use this mandate “responsibly” to deal with the Covid-19 situation and economic downturn, to take Singapore “safely through the crisis and beyond”.

“The results reflect the pain and uncertainty that Singaporeans feel in this crisis, the loss of income, the anxiety about jobs, the disruption caused by the circuit breaker and the safe distancing restrictions,” he said.

This was not a “feel-good” election, said Lee, Singapore’s third prime minister who faces the city state’s worst recession with the economy projected to shrink between 7 and 4 per cent.

Lee acknowledged that the result also showed a “clear desire” for a diversity of voices in Parliament.

“Singaporeans want the PAP to form the government, but they, and especially the younger voters, also want to see more opposition presence in parliament,” he noted.

Lee added that he looks forward to the participation and contribution of the Opposition in parliament.

Singh, whose Workers’ Party team retained Aljunied Group Representation Constituency (GRC), will have 10 elected MPs now, up from six previously. His fellow member also retained the Hougang single-member constituency seat.

“Whether it works out… and whether it’s seen as a strengthening of Singapore will depend not only on what the PAP does but also on what the Opposition does because the Opposition now has 10 MPs elected from constituencies,” said Lee.

He assured that the ruling party will listen to Singaporeans and do its best to address their concerns, and “try to win” their support, whether or not they voted for the PAP.

When asked by the media if the party had lost the youth vote, he noted that different generations have different life experiences, and the young have significantly different life aspirations and priorities compared to the older generations.

“That’ll have to be reflected in our political process and in the government’s policies because, in the end, the government’s policies must be to achieve the aspirations of every generation of Singaporeans,” Lee said, assuring Singaporeans.

He hoped that the new generations of Singaporeans “look critically, but with an open mind” at what previous generations have done, “examine what’s relevant and what continues to make sense to them in a new environment” and “learn from these experiences hard-won by their parents and grandparents”.

This is so that they do not have to “learn them all over again and pay a high price which has already been paid”.

Lee added that he was, naturally, disappointed at the loss of the newly formed Sengkang GRC, which the Workers’ Party won with 52.13 percent of the valid votes.

“Ng Chee Meng and his team -- Lam Pin Min, Amrin Amin and Raymond Lye -- always knew it was going to be a tough fight,” he said.

“They gave it their all, but Sengkang voters have spoken, and we respect their decision.”

Lee described it as a “major loss to my team” and to the fourth-generation leaders, especially as Ng is the secretary-general of the Labour Movement, the NTUC.

Singh, 43, told a press conference following the results that his team would “continue to endeavour for good outcomes on the ground” and to represent voters “faithfully in parliament”.

“Today’s results are positive, but we have to hit the ground running. We should not get over our head with the results. There’s much work to do. And I can assure you this Workers’ Party team is committed to serve Singapore,” he stressed.

The PAP contested all 93 seats and the Workers’ Party 21 seats. Nine other political parties also contested the elections.

A total of 192 candidates contested for seats through 17 Group Representation Constituencies (GRCs).
