What does COVID-19 mean to the athlete’s heart?Health and fitness | Instant News

With millions of Americans participating in high school, college, professional or master-level sports, even if the incidence of complications is low, it may cause a large number of athletes to be affected. This can lead to tricky discussions about how to balance the risk of a small number of athletes who may endanger our continued sports competition.

Her season is over, but more importantly, Washington athletes in excellent physical condition face the possibility of losing their lives. She learned about the 23-year-old Loyola Marymount basketball star Hank Gathers, who fell in a game in 1990 and died within hours. His autopsy confirmed an enlarged heart and myocarditis.

Washington said, “That really made me sit down.” “I thought,’Well, I have to take this seriously because I don’t want to do that and it’s over.'”

For several months, she had to keep her heart rate below 110 beats per minute. Before, she ran 5 miles a day. After the diagnosis of myocarditis, she must wear a heart monitor, and even a brisk walk may cause her to exceed this threshold.

Washington recalled: “I walked to the gym once, maybe I walked a little faster.” “My chest was really tight.”

However, by mid-January, another MRI showed that the inflammation had cleared, and she resumed exercise thereafter.

EU ‘essential travel’ dilemma after Lisbon trip forces top officials to quarantine – POLITICO | Instant News

Press game to listen to this article EU officials insisted on Monday that a visit to Lisbon by a high-level Brussels delegation was “essential business”, even though the trip led three European commissioners to isolation due to the risk of coronavirus infection. Friday’s visit, led by Commission President Ursula von der Leyen, aimed to present the start of the Portuguese Presidency of the Council of the EU. But as the country’s healthcare system is on the brink of collapse following a spike in COVID-19 infections, the trip has raised thorny questions about how the EU decides which official trip is sufficiently ‘essential’ to make an exception to national foreclosure measures. Commission Executive Vice-Presidents Valdis Dombrovskis and Margrethe Vestager and Cohesion and Reform Commissioner Elisa Ferreira were quarantined the weekend following their trip. Their isolation was necessary after Portuguese Finance Minister João Leão tested positive for the virus on Saturday. The trip also raised the question of whether Portuguese Prime Minister António Costa placed a higher priority on promoting publicity for the rotating presidency than on protecting the health of dozens of national officials who participated in the events of Friday. The questions put to Costa’s government are particularly troubling given that Portuguese hospitals are running out of intensive care beds. The country is also campaigning for a presidential election on Sunday and many voters are worried about whether it is safe to vote. Josep Borrell during an interview in Lisbon | Pedro Rocha / European Union Although Portugal’s foreclosure regulations provide exemptions for political events, the government and the EU should have set a better example, said Ricardo Mexia, president of the Portuguese National Association of Medical Doctors public. “During this critical moment, it really would have been better to refrain from any unnecessary contact,” Mexia said. “Messaging is very important. We ask people to stay at home, to find ways to live at a distance, to use technology to meet and work. Politicians must participate in this message. Portuguese and Commission officials, however, insisted on the need to meet in person. “Despite the masks, we have to look people in the eye. We really need to talk face to face as much as possible, ”said Ana Paula Zacarias, Portuguese Secretary of State for European Affairs, at a press conference. “The Lisbon meeting was absolutely productive. We have discussed all the elements and the agenda is full ”, insisted Zacarias, the physical presence of the delegation“ was absolutely fundamental for us to continue the discussion and move forward on many issues. Yet questions arise not only about the nature of the work, but also whether sufficient effort was made to keep meetings short and to the point. A Vestager spokesperson said the risk of the executive vice president’s contact came from sitting at the same table as Leão. The Commission said the decision to hold a dinner meeting was taken by the Portuguese hosts. Commissioner Elisa Ferreira meets Minister Nelson de Souza | Pedro Rocha / European Union While the Commission said the overall trip was essential, officials clearly recognized the risks and tried to mitigate them by reducing the size of the delegation to eight. Often, the entire College of Commissioners, made up of 27 members, travel for such visits at the start of the Presidencies. During the Commission’s daily press conference on Monday, von der Leyen’s chief spokesperson Eric Mamer was faced with a barrage of inquiries about the day’s trip to the Portuguese capital. When a reporter asked why half of the College needed to travel, Mamer insisted on correcting the number first: “Rather, a third of the College traveled,” he said. Mamer has repeatedly said that face-to-face meetings are “essential” to launch the Portuguese Presidency. He also pointed out that the event was held at the invitation of Portugal and that almost all of the Commission’s activities are now being conducted online due to the pandemic. “As to whether it was a good idea in hindsight to go on a mission or not: what I can say is that of course these decisions are not taken lightly,” said Mamer. “The president has given some thought to this, but it is seen as an essential mission because it is the launch of an extremely important presidency.” The fallout was immediately apparent. Ferreira’s quarantine forced her to participate remotely in a press conference Monday on the launch of the ‘European Bauhaus’ – a flagship initiative that von der Leyen pointed out in his September address on the state of the world. Union. While Mariya Gabriel, Commissioner for Innovation, Research, Culture, Education and Youth, appeared in person, Ferreira was first able to be heard but not seen. For a few minutes, she remained a disembodied voice until she appeared on a screen within a screen. About halfway through Ferreira’s opening remarks, issues with the audio stream made her unintelligible. Mamer said Commission officials will continue to assess their travel needs on a case-by-case basis. He did not provide any information on the vaccination plans of senior EU officials, except to say that the vaccinations would eventually be carried out in accordance with Belgian rules. A Portuguese public health doctor said authorities should act faster to vaccinate government officials. “It also puzzles me that they did not vaccinate the Cabinet. Health workers are a priority, of course, but there are only 18 ministers and they are in constant contact with foreign dignitaries, ”the doctor said. “Already vaccinate the damn Cabinet.” The doctor, who spoke on condition of anonymity, criticized Costa for not taking tougher Christmas measures to contain the infections. “Costa was unwilling to cancel Christmas and we have this major outbreak now because of it.” “We are close to where Italy was in March of last year, about two weeks before our hospitals collapsed,” the doctor warned. “I understand that the Commission visit was very important politically, but we are at the top of the list in terms of prevalence and at the moment around 1% of the Portuguese population is currently infected… It was clearly irresponsible of them to come here. Lili Bayer and Sofia Diogo Mateus contributed reporting.

ICU doctors mimic the last moments before COVID-19 death | Instant News

A St. Louis doctor gave a sober first-person perspective on the death of COVID-19. He said that he hopes these shots will encourage more people to wear masks.

Dr. Kenneth E. Remy is an intensive care physician and she also serves as a councillor in Wildwood, Missouri. seriously.

“This is what it looks like when you breathe 40 times per minute and the oxygen content is far below 80 degrees”, Remy Said in the clipHe then placed a tube above the camera to simulate what the patient would see when he was about to hang on the ventilator.

“This is what it looks like. I hope the last moments of life won’t be like this. Because if we don’t wear masks when we are not in public places, this is the end of your life.”

Remy completes the distressing episodes by urging people to wear masks, socialize and wash their hands frequently.

He reiterated: “Because I assure you, this is what you see.” “I assure you, this is what your mother, father or child will see at the end of life when they get COVID-19. serious.”

As of Tuesday, the virus has killed 3,750 Missouri residents and infected nearly 279,000 people. Status data display.

In St. Louis, Remy filmed his video in the Intensive Care Unit (ICU) of the Missouri Baptist Medical Center (Musouri Baptist Medical Center). In the past 10 days, the number of coronavirus cases, hospitalizations and deaths has hit a record. Reached a record high, “St. Louis Post” report.

Remy said that he remembered the impassionedness of those who refused to wear a mask or chose not to wear a mask as a political statement.

Remy told the newspaper: “Wearing a mask without getting sick is the best way to protect your freedom.”

“When I insert the breathing tube into your body and you die, your personal freedom is not important to you.”

He added that he had to tell 11 families in the past week that their relatives succumbed to COVID-19.

Remy said: “This is the worst way of conversation ever.”

According to data from Johns Hopkins University, the United States has reported more than 12.4 million COVID-19 cases, resulting in at least 258,666 deaths.

“Reconnecting” metabolism in insulin-producing cells may help the treatment of type 2 diabetes-health | Instant News

Researchers have discovered a previously unknown method by which pancreatic cells determine how much insulin they secrete.It could provide a promising new target to develop drugs to increase insulin production in diabetic patients Type 2 diabetes.

In two recently published papers Cell metabolismScientists at the University of Wisconsin-Madison and their colleagues pointed out that an overlooked enzyme called pyruvate kinase is the main way for pancreatic beta cells to sense sugar levels and release the right amount of insulin.

Through several proof-of-concept experiments conducted on rodent and human pancreatic cells, the research team found that drugs that stimulate pyruvate kinase not only increase insulin secretion, but also have other metabolic protective effects on the liver, muscles, and red blood cells. Research results indicate that activation of pyruvate kinase may be a new way to increase insulin secretion to fight type 2 diabetes, but more research is needed before any new treatments are available.

Matthew Merrins, professor of medicine at the University of Western Australia School of Medicine and School of Public Health, who is in charge of this work, said: “Too much insulin will lower blood sugar to dangerous levels, and too much insulin can lead to diabetes.” The question to ask is: How do nutrients such as glucose and amino acids open up the beta cells in the pancreas to release the right amount of insulin?”

This work is based on a careful analysis of the contradictory timing of key biochemical events, when it was generally understood how pancreatic beta cells respond to nutrients in the blood. The researchers pointed out a new and richer model to understand how to control this important process to resolve these contradictions.

For decades, scientists have believed that mitochondria, the energy generators in cells, trigger insulin secretion. This is a natural explanation, because mitochondria produce the high-energy molecule ATP, and in the process deplete the low-energy form of ATP, ADP. The decline in ADP stimulates calcium, the ultimate trigger for the release of stored insulin.

But time makes no sense. Mitochondria are most active when insulin secretion has already begun, not before. In addition, the mitochondria will stall before they exhaust enough ADP to trigger insulin secretion.

The clues to resolve these obvious paradoxes came from the study of cardiomyocytes in the 1980s. At the time, scientists discovered that pyruvate kinase (which converts sugar into energy and does not rely on mitochondria) may also severely deplete ADP. This process occurs near the ADP sensor protein involved in insulin release in the pancreas. Mellins’ team believes that perhaps the pancreas uses this proximity to fine-tune insulin release.

In the initial experiment, the researchers provided sugar and ADP to pancreatic cell slices containing pyruvate kinase. Enzymes engulf these two components and deplete ADP. Since pyruvate kinase is located near the ADP sensor protein that triggers insulin secretion, it has a great effect.

“This is one of the important concepts in our paper: The location of the metabolism is critical to its function,” Merrins said.

The researchers used mouse and human islets, clusters of cells that release insulin, to try to stimulate the activity of pyruvate kinase. The drug that activates this enzyme increases the release of insulin four-fold, but only if there is enough sugar around-pyruvate kinase cannot be forced to release too much insulin.

Merrins said: “Pyruvate kinase does not change the amount of fuel that enters the cell, but only changes the way the fuel is used.” “Drugs with active pyruvate kinase can strongly promote insulin secretion without causing excessive insulin release. Hypoglycemia.”

Overall, they found a more complicated way, which is evidence of how pancreatic beta cells decide when and how much insulin they release, similar to a two-stroke engine. In the first cycle, pyruvate kinase processes blood sugar and consumes ADP. Mitochondria maintain this process by supplying more material to pyruvate kinase, which can cause ADP levels to collapse and ultimately stimulate enough calcium to enter the cell to release insulin.

In the second cycle, mitochondria transition from adding material to pyruvate kinase to producing the high-energy molecule ATP, which is necessary for the complete release of insulin. Then, the process will reset.

In an accompanying study by colleagues at Yale University Mellins, researchers studied how pyruvate kinase activator affects the metabolism of healthy and obese rats. In a series of experiments, they found that activating pyruvate kinase can increase insulin secretion and insulin sensitivity, while improving glucose metabolism in the liver and red blood cells. This type of treatment may be useful for patients with type 2 diabetes, who cannot produce enough insulin and therefore have abnormal glucose metabolism.

Mellins said: “The therapeutic idea here is that we can rearrange our metabolism to trigger insulin secretion more effectively while improving the function of other organs.

A nurse practitioner in Florida is filing a legal action against her boss. She said that when he contracted the coronavirus at the local workplace, he would deliberately cough at her. news report.

Venise Jean-Baptist told local news that her boss, Dr. Joseph Piperato, would not take the necessary precautions to prevent the spread of COVID-19, just like working in the medical office of the Project Access Foundation in California When wearing a mask. Miami,according to WSVN TV.

Jean-Baptist told WSVN: “We don’t have N95 masks.” “The masks we have are not allowed to be worn by every patient.” According to the report, Jean-Baptist Alleged that after pestering her boss about using masks and following the guidelines and recommending him to be tested, Piperto coughed at her when she was infected with COVID-19.

according to Miami Herald, litigation It is shown that Jean-Baptist said she was denied the use of a mask and was prohibited from using the COVID-19 test kit. The lawsuit said: “The medical director further informed Jean-Baptiste that the reason why personnel are not allowed to conduct inspections is that if someone tests positive, they don’t want to close the office within two weeks.” “Therefore, without a test, it won’t There are positive tests.”

The Project Access Foundation issued a statement in response to Jean-Baptist’s allegations.
