W.H.O. Testing three Medicine in Broad Seek for Covid Remedies

The World Health Organization is testing three more drugs as part of a huge global study to find effective treatments for Covid-19, the agency said on Wednesday.

The study, which will involve researchers in more than 600 hospitals in 52 countries, will evaluate whether the drugs already approved for other uses – one for malaria, one for cancer and one for autoimmune diseases – can reduce the risk of death for patients with Covid to be hospitalized.

Dr. Tedros Adhanom Ghebreyesus, WHO director general, said Wednesday he hoped “one or more of the drugs” would prove effective in treating the virus.

Although there are already some treatments out there for people with Covid-19, including steroids and monoclonal antibodies, Dr. Tedros: “We need more for patients at all ends of the clinical spectrum.”

The first phase of the WHO’s trials of new drugs, which it called Solidarity, yielded disappointing results. The researchers found that four different drugs, including hydroxychloroquine and the antiviral drug remdesivir, had little or no benefit for hospitalized Covid patients.

The three drugs in the new study, named Solidarity Plus, were selected by an independent panel of experts and are donated by their manufacturers Ipca, Novartis and Johnson & Johnson. The drugs are artesunate, an antimalarial drug that may have anti-inflammatory effects; Imatinib, a cancer drug that could reverse damage to the lungs; and infliximab, an autoimmune disease drug that may help curb an overly aggressive immune response to the virus.

It’s Arduous to Seek for a Therapist of Coloration. These Web sites Need to Change That.

Other organizations go a step further and help patients make therapy appointments. The non-profit Black Men Heal, for example, offers up to eight free online consultations. About 70 percent of clients choose to pay for additional sessions, said executive director Tasnim Sulaiman, a private practice psychotherapist in the Philadelphia area who founded the organization in 2018.

It can be difficult for people of color to find a therapist with a common cultural background. About 18 percent of people in the United States identify as Hispanic and 13 percent as Black, according to the Census Bureau, but a report by the American Psychological Association found that only 5 percent of psychologists are Hispanic and 4 percent are Black – 86 percent are white. Similar inequality exists among the country’s social workers and psychiatrists.

Eric Coly, who previously worked in finance, founded Ayana Therapy in 2020, about eight years after rock bottom with anxiety and depression.

At the time, he struggled to find a therapist who could understand the intersection of his different identities as blacks and immigrants from Senegal who had lived in different parts of the world.

“This product was almost meant to heal the way I used to be,” he said.

Ayana, which means “mirror” in Bengali, asks users to fill out a questionnaire designed to capture “your many nuances,” said Mr. Coly, then put you in touch with a culturally competent therapist. The cost of each online session is currently $ 60.

Providers are verified through a process that includes two interviews and reference reviews.

While Ayana was created for a variety of races and cultures, as well as for those who identify as LGBTQ, some websites cater to a more niche group of users such as LatinxTherapy, Therapy for Black Girls, Therapy for Black Men, the Asian Mental Health Collective and the National Queer and Trans Therapists of Color Network. Melanin and Mental Health has a directory of color therapists, many of whom are in Houston. The Black Emotional and Mental Health Collective, a nonprofit wellness organization that trains people to respond to mental crises, has an online directory of a wide variety of black practitioners, including therapists, yoga teachers, doulas, and mediators.

Employers are also increasingly recognizing the need for culturally competent providers. Indeed, Thumbtack, and Critical Mass, part of the Omnicom Group, recently partnered with Therify, which uses artificial intelligence technology to connect employees with vendors in their state. Half of Therify’s nearly 300 online therapists are People of Color and 20 percent specialize in serving clients who identify as LGBTQ, said the company’s CEO James Edward Murray, who interviews each provider.

Search shifts from rescue to restoration

Search and rescue teams continue to work in the rubble of the collapsed Champlain Towers South apartment in Surfside, Florida on July 6, 2021.

Searching the site of a Florida condo building collapse has shifted from a rescue operation to a salvage operation as the likelihood of finding survivors decreases, Miami-Dade County Mayor Daniella Levine Cava said at a news conference Wednesday afternoon.

For two weeks, rescue teams have spent a painstaking search and rescue effort to find more victims in the rubble of the collapsed Champlain Towers South in Surfside, Florida. But the possibility of finding someone alive is “near zero,” according to Surfside Charles Mayor Burkett.

Levine Cava also announced that the death toll has risen to 54, of which 86 are not yet known.

“I couldn’t be more proud of our team. The extraordinary men and women from here, at home and from around the world who have given this search everything they have every day,” said Levine Cava.

“At this point we have really exhausted all of the options available to us on the search and rescue mission. Today is about beginning the transition to recovery so we can help finish the families who are suffering and waiting for us. “

The transition from rescue to salvage will be at midnight tonight and will be marked by a moment of silence in front of the construction site with first responders and faith leaders, Levine Cava added.

Search and rescue teams were able to reach areas of the pile that were inaccessible prior to the building’s demolition on Sunday evening without first responders injuring despite difficult conditions at the site, Levine Cava said.

The building was demolished in a controlled demolition on Sunday amid concerns that the standing structure was unstable and could fall on first responders.

Weather conditions cleared Wednesday so rescue teams could continue their search efforts despite initial concerns about having to temporarily suspend work, Levine Cava said in the morning. Forecasters downgraded Elsa from hurricane to tropical storm on Wednesday after hitting land on Florida’s northern Gulf coast.

The emergency management department has received 42 resource requests from citizens affected by Tropical Storm Elsa, with Lt. Gov. Jeanette Nuñez experienced more than 26,000 power outages.

More than 10,000 employees are ready to respond to these failures and provide resources such as water, food and generators, added Nuñez.

After a brief stop to tear down the standing rubble, search and rescue workers will continue to work in the rubble of the partially collapsed 12-story Champlain Towers South apartment on July 5, 2021 in Surfside, Florida.

Surfside Vice Mayor Tina Paul said authorities are working to find long-term housing for survivors of the condominium collapse, many of which are still staying in hotels.

“That is also a priority just to rebuild their lives,” Paul said. “The best way to start is to have a home to call your own.”

Paul added that authorities have received several inquiries from board members and condominium presidents regarding the safety of their buildings. The City of Surfside issued a press release calling for a geotechnical survey of properties more than 30 years old, but Paul said better recommendations are being developed.

Levin Cava also said Miami-Dade County continues to move forward with a 30-day audit that evaluates all four-story residential properties that are 40 years or older and “have not completed the process of identifying and resolving issues.”

The county assessed a total of 40 buildings as part of the audit and identified one building with four balconies that was classified as unsafe according to Levine Cava. While the building was not being evacuated, the balconies were immediately closed.

The remaining portion of the partially collapsed 12-story Champlain Towers South Condo building is falling into controlled demolition on July 4, 2021 in Surfside, Florida.

Other cities, like North Miami Beach and Miami Beach, have also started conducting their own audits, she added.

“There will be changes, there will be improvements,” said Levine Cava.

Surfside Mayor Burkett also briefed on Champlain Towers North, the sister building of the collapsed condominium building. Engineers and authorities are currently checking whether it is safe for residents to live on the sister property.

Burkett said it would take several weeks to gather sufficient evidence of structural problems with the building.

The cause of the collapse of the apartment building is still unknown.

Recent evidence shows that the 40-year-old building showed signs of structural damage as early as 2018, with waterproofing problems under the pool and cracks in the underground car park.

Search paused as authorities put together for demolition

Search-and-rescue operations at the partially collapsed condominium tower in Surfside, Florida came to a temporary halt Saturday, as authorities move to raze the rest of the building in a controlled demolition before the unstable structure is threatened by winds from Tropical Storm Elsa.

During a press briefing, Miami-Dade Mayor Daniella Levine Cava said operations were paused temporarily at 4:00 p.m. ET Saturday due to preparations for the demolition, which includes drilling into unstable columns. The search can restart once the remaining part of the building is demolished.

“We’re proceeding as quickly as we possibly can,” Levine Cava said Saturday evening.

“It is all of our fervent desire that this can be done safely before the storm so that we can direct the demolition,” the mayor said earlier Saturday. “This demolition would be one that would protect and preserve evidence and allow maximum search-and-rescue activity to continue.”

The death toll from the fallen building rose to 24 as of Saturday, and 121 people are still missing. No one has been rescued since the first few hours after Champlain Towers South, a 12-story condominium built in 1981, partially collapsed on June 24.

Florida Gov. Ron DeSantis said the building can be brought down within 36 hours once the final plan is in place, while Surfside Mayor Charles Burkett said the demolition could occur as early as Sunday.

“The fear was that the hurricane might take the building down for us and take it down in the wrong direction on top of the pile where we have victims,” Burkett said, referring to Elsa which was downgraded to a tropical storm Saturday.

Levine Cava signed a local state of emergency for Elsa on Saturday morning. “Out of an abundance of caution, we’re ensuring we’re mobilizing everything we need in the county to prepare for any possible impacts,” she said at the briefing.

The long-term forecast track shows Elsa heading toward Florida as a tropical storm by Tuesday morning, but some models would carry it into the Gulf or up the Atlantic Coast.

The accelerated plan comes a day after Levine Cava said the demolition might not occur for weeks as engineers studied and signed off on next steps. Officials have restricted access to parts of the building zone that threaten public health and safety.

However, Levine Cava said a demolition expert came forward Friday evening with the experience to move more quickly than originally anticipated. Engineers and state, local and federal authorities reviewed the plan and agreed it was the best path forward, Levine Cava said.

“This proposed demolition is a very narrow footprint so we’re not looking at major impacts to the area or additional evacuations,” Levine Cava said. “We are still in the due diligence process.”

The decision to demolish the portion of the building that’s still standing comes after search-and-rescue operations were halted most of Thursday out of concern that the remaining structure could fall, endangering first responders searching the site.

The cause of the building collapse is still unknown. An engineering firm reviewed the condo tower in 2018, nearly three years before the collapse, and issued a report which found failed waterproofing below the building’s pool was causing “major structural damage.”

“Failure to replace the waterproofing in the near future will cause the extent of the concrete deterioration to expand exponentially,” the report said.

The National Institute of Standards and Technology has launched a full investigation into the collapse and will make recommendations about how to improve building safety.

Levine Cava ordered a 30-day audit of buildings 40 years or older in Miami-Dade County which are five stories or taller and have not completed the re-certification process. The county is reviewing 14 such buildings and 10 that recently began recertification.

A condo building in North Miami Beach was closed and more than 300 residents evacuated Friday after an audit and building inspection report found unsafe structural and electrical conditions.

Search and rescue operations in a Florida condo collapse resumed Thursday after a one-day shutdown, Miami-Dade County Mayor Daniella Levine Cava said at a press conference Thursday evening.

The decision to resume operations was made around 4:45 p.m. Thursday after civil engineers said conditions were safe enough, Levine Cava said. Operations were suspended Thursday morning over concerns that the rest of the building could collapse.

“I am grateful for your hard work in getting us back to search and rescue as quickly as possible,” said Levine Cava. “Of course, we continue to assure that we are doing everything we can to protect our first aiders.”

The death toll remained unchanged through Thursday, with 18 confirmed deaths and 145 missing, according to Levine Cava.

While search and rescue is the authorities’ top priority, plans to demolish the building are currently underway, Levine Cava told reporters.

Miami-Dade Fire Rescue chief Alan Cominsky said all task force leaders, division group leaders, and heavy equipment operators had been briefed of a search resumption plan with security measures.

Authorities are restricting access to parts of the collapse zone that raise safety concerns, Levine Cava said. Technologies such as cameras and drones are used to search inaccessible areas of the building.

A team of engineers are also conducting tests and evaluations to safely expand the search area, she added.

Levine Cava and other authorities also thanked President Joe Biden and First Lady Jill Biden for visiting Surfside early Thursday, noting that Biden offered comfort to families affected by the collapse.

Kevin Guthrie, director of the Florida emergency management department, added that Biden has pledged to cover 100% of reimbursements for local governments facing deficits due to the breakdown.

Emergency Management Director Charles Cyrille also briefed on Tropical Storm Elsa, which continues to move rapidly through the Caribbean Sea. Cyrille told reporters that the State Department of Emergency Management continues to monitor the storm and that contingency plans are in place.

Cyrille said “Miami-Dade County is not in imminent danger,” but urged citizens to be prepared with disaster packages and evacuation plans.

Cominsky, the chief of the fire department, said the decision to cease operations Thursday morning was based on “additional concerns about building stability” identified by subject matter experts.

These concerns included 15 to 12 inches of movement, a large pillar hanging from the building that could fall and damage the support columns in the underground car park, and slight movement in the concrete floor slabs on the south side of the structure that “could lead to additional failure” . of the building, “says Cominsky.

In the last few days there have been increasing indications that the 40-year-old apartment building had already suffered considerable structural damage in 2018.

A newly discovered video, captured the night of the collapse, shows water pouring into the Champlain Towers parking garage.

On Wednesday evening, the National Institute of Standards and Technology announced it had launched a federal investigation into the causes of the building collapse.

“We are going in with an open mind,” said Judith Mitrani-Reiser, deputy head of the materials and support systems department at NIST, at a press conference near the collapse site on Wednesday.

“Whenever a building collapses, we want to understand how the building was designed, built, modified and maintained,” she said.

Several lawsuits have been filed on behalf of the victims’ families, some of which are still missing.

But the question of who, if anything, was responsible for the breakdown is unlikely to be resolved anytime soon.

James Olthoff, the director of NIST, told the Miami Herald the federal investigation will not attempt to assign the blame for the collapse.

“This is a kind of fact-finding, not troubleshooting, type of investigation,” he told the Herald. “It will take time, possibly a few years.”

Two New Legal guidelines Limit Police Use of DNA Search Methodology

In other cases, detectives might surreptitiously collect the DNA of a suspect’s relative by testing an object that the relative discarded in the trash.

Maryland’s new law states that when police officers test the DNA of “third parties” — people other than the suspect — they must get consent in writing first, unless a judge approves deceptive collection.

Investigators cannot use any of the genetic information collected, whether from the suspect or third parties, to learn about a person’s psychological traits or disease predispositions. At the end of the investigation, all of the genetic and genealogical records that were created for it must be deleted from databases.

And perhaps most consequential, Maryland investigators interested in genetic genealogy must first try their luck with a government-run DNA database, called Codis, whose profiles use far fewer genetic markers.

Mr. Holes said that this part of the law could have tragic consequences. For old cases, he pointed out, DNA evidence is often highly degraded and fragile, and every DNA test consumes some of that precious sample. “In essence, the statute could potentially cause me to kill my case,” he said. And given the speed that DNA technology evolves, he added, it is unwise for a law to mandate use of any particular kind of test.

But other experts called this provision crucial, because the potential privacy breach is far more severe for genetic genealogy, which gives law enforcement access to hundreds of thousands of genetic markers, than it is for Codis, which uses only about two dozen markers.

These searches are “the equivalent of the government going through all of your medical records and all of your family records just to identify you,” said Leah Larkin, a genetic genealogist who runs a consulting business in the San Francisco Bay Area that is largely focused on helping adoptees and others find their biological relatives. “I don’t think people fully appreciate how much is in your genetic data.”

Two New Legal guidelines Limit Police Use of DNA Search Methodology

In other cases, detectives can secretly collect DNA from a relative of a suspect by testing an item that the relative threw in the trash.

New Maryland law states that when police officers test the DNA of “third parties” – anyone other than the suspect – they must first obtain written consent, unless a judge approves a misleading collection.

Investigators cannot use any of the genetic information gathered from the suspect or third parties to obtain information about a person’s psychological characteristics or susceptibility to illness. At the end of the examination, all genetic and genealogical records created for this purpose must be deleted from the databases.

Perhaps most momentous, Maryland researchers interested in genetic genealogy must first try their luck with a government-run DNA database called Codis, whose profiles use far fewer genetic markers.

Mr Holes said that part of the law could have tragic consequences. In ancient cases, he pointed out, DNA evidence is often badly degraded and fragile, and each DNA test uses up some of this valuable sample. “Essentially, the law could make me kill my case,” he said.

However, other experts cited this provision as critical, as the potential invasion of privacy is far more serious for genetic genealogy, which gives law enforcement access to hundreds of thousands of genetic markers, than it is for Codis, which only uses about two dozen markers.

Unemployment Job Search Necessities Return. Is It Too Quickly?

One of the tenets of the American unemployment system was that anyone with benefits in good times and bad should look for work.

That consideration changed at the beginning of the pandemic. The pervasive fear of contagion and the sudden need for millions of workers to become caregivers led states to lift the requirements for practical and compassionate reasons.

But as vaccinations increased and the economy revived, more than half of all states have revived their job search requirements. Arkansas and Louisiana did this months ago to push workers out of their swollen unemployment figures. Others, like Vermont and Kentucky, have followed suit in the past few weeks.

The rest can be on the way. President Biden on Monday ordered the Department of Labor “to work with the rest of the states, insofar as health and safety conditions permit,” to meet the requirements arising from the pandemic.

Employers can welcome the move as a potential addition to the pool of job seekers. For many workers, however, compulsory search is a premature declaration that the world has returned to normal, despite legitimate concerns about infection with the virus and childcare restrictions.

“The job search is just a mess,” said 34-year-old Tyler Evans, who lost his nearly four-year job at a downtown Nashville restaurant at the start of the pandemic. Mr. Evans’ doctor did not release him to work, warning him that he was at additional risk from the coronavirus due to his autoimmune disease.

However, according to Tennessee, Mr. Evans must complete three job search activities per week in order to continue to be eligible for unemployment benefits. When he explained his situation to the people at the State Labor Department, they suggested that he just say he was looking for a job because the state system had no way of considering health cases like his.

Instead, Mr. Evans diligently applied for jobs every week – even if he couldn’t take any of them.

“I would say one in four times someone would call me back,” he said. “And I have to say, ‘Oh, I can’t actually work for you for health reasons, but the Department of Labor asked me to do it anyway.'”

Research suggests that job search demands in normal economic times may force workers to find their next job and reduce their working hours. But the pandemic has added a new layer to a debate about how relief can be reconciled with the assumption that unemployment is temporary. Most states cut unemployment benefits after 26 weeks.

Business groups say bringing back job search requirements will help juicy the job market and dissuade workers from waiting to return to their old employers or advocating for more remote or better paying jobs.

Opponents claim the mandate discourages an inadequate number of Americans from continuing to receive the benefits they need as it can be difficult to meet the sometimes difficult requirements, including documenting the search efforts. And they say workers may be forced to apply for and accept poorly paid or less satisfactory jobs if the pandemic has caused some to rethink their attitudes about their work, family needs, and prospects.

“I think the job search requirements as an economist are necessary,” said Marta Lachowska, an economist at the WE Upjohn Institute for Employment Research in Kalamazoo, Michigan, who studied the impact of job search requirements on employment. But she added, “Perhaps, given the huge disruption we’ve seen in the labor market, people should ease up a little.”

In Washington, the problem has become part of a larger unemployment benefit conflict that worsened after April’s disappointing job report. Republicans claimed that Mr. Biden’s policies were preventing people from looking for work and holding back economic recovery.

A growing number of Republican governors have taken matters into their own hands, seeking to end a $ 300 weekly unemployment benefit and other federal-funded emergency aid that would otherwise not expire until September.

Mr Biden has rejected the criticism of his economic stimulus plan. But its acceptance of job search requirements – more than a year after the federal government ordered states to forego it – has made the practice a pillar in efforts to revitalize the economy.

Tim Goodrich, the executive director for state government relations at the National Federation of Independent Business, said its members have complained about problems filling vacancies – a challenge mitigated by restoring job search requirements could be.

“You see a shortage of applicants, so finding a job is certainly helpful,” Goodrich said.

Job vacancies rose to 8.1 million in March, the Labor Department reported Tuesday, but more than eight million fewer people are working than before the pandemic. Economists attribute some of the mismatch to a temporary discrepancy between the jobs offered and the skills or background of job seekers. They say that in a recovering labor market like this, there may not be enough suitable jobs for people seeking re-employment, which can frustrate workers and lead them to randomly apply for jobs.

Such was the case for 45-year-old Rie Wilson, who was selling venues for a nonprofit in New York City before she lost her job last summer.

To meet New York job hunting requirements, which typically require unemployment applicants to complete at least three job search activities per week, Ms. Wilson had to apply for jobs she would not normally consider, such as job vacancy. B. Jobs as administrative assistant.

She worries about the prospect of getting a job like this.

“I always think, ‘What if I’m pulled in this direction just because I’m forced to apply for these jobs? How does that look for my career? ‘”, She said.

The process was time consuming, she said, “and it’s also mental wear and tear because you literally get pulled from all angles in a very stressful situation.”

Alexa Tapia, the unemployment insurance campaign coordinator at the National Employment Law Project, an employee advocacy group, said job search requirements “do more harm than help”, especially during the pandemic.

In particular, she said, such demands perpetuate systemic racism by including people of color, especially women, in underpaid work with fewer benefits. And she noted that people of color were more likely to be denied services because of such demands.

Since the state employment offices are already overwhelmed, the job search requirements are “just another obstacle for applicants, and it can be a very demoralizing obstacle”.

In states where job search requirements have been reintroduced, workers’ representatives say a particularly frustrating obstacle has been a lack of guidance.

Sue Berkowitz, the director of the South Carolina Appleseed Legal Justice Center, which works with low-income South Carolinians, said unemployed workers in the state largely wanted to return to work. But the information on the state’s website about job search requirements is so confusing that it fears workers will not understand it.

Before the state reintroduced the requirements last month, Ms. Berkowitz sent a flagged copy of the proposed language to the South Carolina Department of Employment and Labor Chief of Staff for clarifications and changes. One of their greatest concerns was that the language in its current form was read in 12th grade, while the typical adult American reading level is much lower. She didn’t hear back. “It was crickets,” she said.

In general, employees in South Carolina, where the minimum wage is $ 7.25 an hour, may be reluctant to take a job that pays less than what they had before the pandemic, Ms. Berkowitz said.

“It’s not that they are under a job that does a lot less, but their financial needs are high enough to continue to earn a certain salary,” she said.

Although job search requirements have become a political issue, their restoration does not fall solely by party-political standards. Florida, for example, where the Republican governor has repeatedly violated virus restrictions, had maintained the job search waiver before recently announcing that it would reintroduce the requirement later this month.

But many other states, especially the Republicans, are in a hurry to bring their job search requirements back.

Crista San Martin found out when she quit her job for health reasons at a kennel in Cypress, Texas, which reintroduced its job search requirements in November.

Mx. San Martin, 27, who uses the pronouns he and she use, said there were very few vacancies in the pet care industry near her, making it difficult to find a job.

“That made it really difficult for me to keep a log of job searches because there just weren’t enough jobs I wanted to take on for my career,” they said. The first job they applied for was with a Panera, “which is not at all in my area of ​​interest”.

Above all, applying for arbitrary jobs is risky, as there is no way to evaluate the Covid-19 security protocols of potential employers. Mx. San Martin has since returned to her old job.

“It’s pretty unfair,” they said. “It’s not safe to go out there and just cast a wide net and see if some random deal gets you.”

UK search thriller particular person contaminated with Brazil Covid variant

UK health officials are keen to track down one in six people infected with a contagious variant of the coronavirus that was originally identified in Brazil.

Up to six cases of the new strain – named P.1 and classified as a “variant of concern” by global health experts – have been identified in the UK, three in Scotland and three in England.

What worries officials, however, is that one of the three cases found in England has not been traced. The government issued a statement on Sunday noting that two of the cases in England came from a South Gloucestershire household and had traveled to Brazil in the past.

The cases in South Gloucestershire, southeast England, were quickly followed up by a team from Public Health England and their contacts were identified and retested, the government said. All passengers on the same flight – Swiss Air flight LX318 from Sao Paulo via Zurich to London Heathrow on February 10 – were also followed by officials.

As a precautionary measure, health officials are stepping up testing of asymptomatic cases in the South Gloucestershire area and increasing sequencing of positive samples from the area.

The mysterious case

However, further research is ongoing into a separate third case of the variant identified in England. The health authorities are calling on anyone who did not receive the result of a Covid test carried out on February 12 or 13 to report.

“The person did not fill out their test registration card, so no follow-up details are available,” the government stated.

“We therefore ask anyone who took a test on February 12th or 13th and has not yet received the result or has an incomplete test registration card to call 119 in England or 0300 303 2713 in Scotland for assistance as soon as possible receive.”

UK Health Secretary Matt Hancock will hold a meeting later Monday to inform UK lawmakers of all parties of the variant, the BBC reported.

Why are officials concerned?

Health officials are concerned because the variant first identified in Brazil is believed to be a more contagious strain of the coronavirus and could cause more severe infections. There are also concerns that it could make coronavirus vaccines less effective. However, this is not confirmed and research is being carried out to see if it is.

While scientists are doing this research, vaccine manufacturers are developing booster vaccinations for target variants.

The UK is already grappling with the spread of a far more contagious variant, which was responsible for an increase in cases over the winter. The strain has since become dominant in the country and has spread worldwide.

The latest weekly report from the World Health Organization said 101 countries have now reported cases of the variant first identified in the UK.

Regarding the strain found in Brazil, it said 29 countries have reported cases so far. This P.1 variant was first identified in four travelers from Brazil to Japan in January during a routine screening at Haneda Airport outside Tokyo.

The strain has been classified as “Concerning” because it has some crucial mutations with the variant first identified in South Africa. According to the US Centers for Disease Control and Prevention, the P.1 variant has a total of 17 unique mutations and was first detected in the US at the end of January.

regulate

When the first cases of this variant were discovered in the UK, people traveling from abroad had to self-isolate at home for 10 days.

However, that changed on February 15th and now travelers to the UK must be quarantined in hotels for 10 days at their own expense. In mid-January, Great Britain banned travelers from various South American countries from entering the country unless they had a right of residence.

The move was an attempt to prevent the spread of infectious variants and potentially undermine the previously successful introduction of the coronavirus vaccine in the country. The UK reached another milestone on Sunday after vaccinating 20 million people with a first dose of a Covid vaccine.

Dr. Susan Hopkins, PHE’s Strategic Response Director for Covid-19 and NHS Test and Trace Medical Advisor, said the new cases in the UK were identified thanks to the country’s advanced sequencing capabilities, “which means we are finding more variants and mutations than many other countries.” and are therefore able to act quickly. “

“The most important thing is that whatever the variant, Covid-19 spreads the same way. That means the measures taken to contain the spread won’t change,” she said, advocating good personal hygiene and leaving only the house for essential reasons.

Scotland’s Falls

The three cases identified in Scotland were found in people returning to Aberdeen from Brazil via Paris and London. These cases are not related to the three cases in England.

As required at the time, the individuals entered self-isolation upon their return to Scotland and subsequently tested positive for coronavirus. The people then self-isolate for the required 10-day period, the Scottish Government said in a statement.

Due to possible concerns about this variant, other passengers on the flight from London to Aberdeen were contacted, the Scottish government found.

How the Seek for Covid-19 Therapies Faltered Whereas Vaccines Sped Forward

Fast ein Jahr nach Beginn der Coronavirus-Pandemie, da in den USA täglich Tausende von Patienten sterben und die weit verbreitete Impfung noch Monate entfernt ist, haben Ärzte nur wenige Medikamente zur Bekämpfung des Virus.

Eine Handvoll Therapien – Remdesivir, monoklonale Antikörper und das Steroid Dexamethason – haben die Versorgung von Covid-Patienten verbessert und die Ärzte in eine bessere Position gebracht als zu dem Zeitpunkt, als das Virus im vergangenen Frühjahr anstieg. Aber diese Medikamente sind keine Allheilmittel und nicht jedermanns Sache, und die Bemühungen, andere Medikamente wiederzuverwenden oder neue zu entdecken, waren nicht sehr erfolgreich.

Die Regierung investierte 18,5 Milliarden US-Dollar in Impfstoffe, eine Strategie, die zu mindestens fünf wirksamen Produkten mit Rekordgeschwindigkeit führte. Die Investitionen in Medikamente waren jedoch weitaus geringer, etwa 8,2 Milliarden US-Dollar, von denen die meisten nur an wenige Kandidaten gingen, beispielsweise an monoklonale Antikörper. Studien zu anderen Medikamenten waren schlecht organisiert.

Das Ergebnis war, dass viele vielversprechende Medikamente, die die Krankheit frühzeitig stoppen könnten, sogenannte Virostatika, vernachlässigt wurden. Ihre Studien sind ins Stocken geraten, entweder weil die Forscher nicht genügend Mittel oder Patienten zur Teilnahme gefunden haben.

Gleichzeitig haben einige Medikamente trotz enttäuschender Ergebnisse nachhaltige Investitionen erhalten. Es gibt jetzt eine Fülle von Beweisen dafür, dass die Malariamedikamente Hydroxychloroquin und Chloroquin nicht gegen Covid wirkten. Laut dem Covid Registry of Off-Label & New Agents an der University of Pennsylvania gibt es dennoch 179 klinische Studien mit 169.370 Patienten, in denen zumindest einige die Medikamente erhalten. Und die Bundesregierung hat zig Millionen Dollar in ein erweitertes Zugangsprogramm für Rekonvaleszenzplasma gesteckt, das fast 100.000 Covid-Patienten infundierte, bevor es belastbare Beweise dafür gab, dass es funktionierte. Im Januar haben diese Studien gezeigt, dass dies zumindest bei Krankenhauspatienten nicht der Fall ist.

Das Fehlen einer zentralisierten Koordination führte dazu, dass viele Studien mit Covid-Virostatika von Anfang an zum Scheitern verurteilt waren – zu klein und schlecht konzipiert, um nützliche Daten zu liefern, so Dr. Janet Woodcock, die amtierende Kommissarin der Food and Drug Administration. Wenn die Regierung stattdessen ein organisiertes Netzwerk von Krankenhäusern eingerichtet hätte, um große Studien durchzuführen und Daten schnell auszutauschen, hätten die Forscher jetzt viel mehr Antworten.

“Ich beschuldige mich bis zu einem gewissen Grad”, sagte Dr. Woodcock, der die Bemühungen der Bundesregierung zur Entwicklung von Covid-Medikamenten überwacht hat.

Sie hofft, das Chaos mit neuen Anstrengungen der Biden-Administration zähmen zu können. In den nächsten Monaten, sagte sie, plane die Regierung, große und gut organisierte Studien für bestehende Medikamente zu starten, die zur Bekämpfung von Covid-19 umfunktioniert werden könnten. “Wir arbeiten aktiv daran”, sagte Dr. Woodcock.

Brandneue antivirale Medikamente könnten ebenfalls helfen, aber erst jetzt stellen die National Institutes of Health eine wichtige Initiative zusammen, um sie zu entwickeln, was bedeutet, dass sie nicht rechtzeitig bereit sind, die aktuelle Pandemie zu bekämpfen.

“Es ist unwahrscheinlich, dass diese Bemühungen im Jahr 2021 Therapeutika liefern”, sagte Dr. Francis Collins, der Leiter des NIH, in einer Erklärung. “Wenn ein Covid-24 oder Covid-30 kommt, wollen wir vorbereitet sein.”

Obwohl die Zahl der Fälle und Todesfälle im ganzen Land gestiegen ist, hat sich die Überlebensrate der Infizierten erheblich verbessert. Eine kürzlich durchgeführte Studie ergab, dass die Sterblichkeitsrate der Krankenhausinsassen bis Juni von 17 Prozent zu Beginn der Pandemie auf 9 Prozent gesunken war, ein Trend, der in anderen Studien bestätigt wurde. Forscher sagen, dass die Verbesserung teilweise auf das Steroid Dexamethason zurückzuführen ist, das die Überlebensraten schwerkranker Patienten erhöht, indem es das Immunsystem unterdrückt, anstatt das Virus zu blockieren. Patienten suchen möglicherweise auch früher im Verlauf der Krankheit Pflege. Und Masken und soziale Distanzierung können die Virusexposition verringern.

Als sich das neue Coronavirus Anfang 2020 als globale Bedrohung herausstellte, versuchten die Ärzte verzweifelt, eine Auswahl bestehender Medikamente zu finden. Die einzige Möglichkeit, festzustellen, ob sie tatsächlich arbeiteten, bestand darin, große klinische Studien durchzuführen, in denen einige Personen Placebos erhielten und andere das betreffende Medikament einnahmen.

Hunderte oder Tausende von Menschen in solche Prozesse zu bringen, war eine enorme logistische Herausforderung. Anfang 2020 beschränkte sich das NIH auf einige vielversprechende Medikamente. Diese Unterstützung führte zur raschen Zulassung von Remdesivir- und monoklonalen Antikörpern. Remdesivir, das die Replikation von Viren in Zellen verhindert, kann die Zeit, die Patienten zur Genesung benötigen, geringfügig verkürzen, hat jedoch keinen Einfluss auf die Mortalität. Monoklonale Antikörper, die das Eindringen des Virus in die Zellen verhindern, können sehr wirksam sein, jedoch nur, wenn sie verabreicht werden, bevor Menschen krank genug sind, um ins Krankenhaus eingeliefert zu werden.

Hunderte von Krankenhäusern und Universitäten begannen ihre eigenen Versuche mit bestehenden Medikamenten, die bereits als sicher und weit verbreitet gelten und möglicherweise auch gegen das Coronavirus wirken. Die meisten dieser Studien waren jedoch klein und unorganisiert.

In vielen Fällen waren die Forscher allein, um Studien ohne die Unterstützung der Bundesregierung oder der Pharmaunternehmen durchzuführen. Im April, als New York City von einer Covid-Welle heimgesucht wurde, hörte Charles Mobbs, Neurowissenschaftler an der Icahn School of Medicine am Mount Sinai, von interessanten Arbeiten in Frankreich, die auf die Wirksamkeit eines Antipsychotikums hinweisen.

Ärzte in französischen psychiatrischen Krankenhäusern hatten festgestellt, dass im Vergleich zu den Mitarbeitern, die sich um sie kümmerten, relativ wenige Patienten an Covid-19 erkrankten. Die Forscher spekulierten, dass die Medikamente, die die Patienten einnahmen, sie schützen könnten. In Laborexperimenten wurde gezeigt, dass eines dieser Medikamente, das Antipsychotikum Chlorpromazin, die Vermehrung des Coronavirus verhindert.

Die Ärzte versuchten, einen Versuch mit Chlorpromazin zu beginnen, aber die Pandemie ließ in Frankreich – wie sich herausstellte – vorübergehend nach, als sie fertig waren. Dr. Mobbs verbrachte dann Wochen damit, Vorkehrungen für einen eigenen Versuch mit Patienten zu treffen, die am Berg Sinai im Krankenhaus waren, um dann gegen dieselbe Wand zu stoßen. “Wir haben keine Patienten mehr”, sagte er.

Wenn Ärzte wie Dr. Mobbs landesweite Netzwerke von Krankenhäusern nutzen könnten, könnten sie genügend Patienten finden, um ihre Studien schnell durchzuführen. Diese Netzwerke existieren, wurden jedoch nicht für die Wiederverwendung von Drogen geöffnet.

Viele Wissenschaftler vermuten, dass der beste Zeitpunkt zur Bekämpfung des Coronavirus früh in einer Infektion liegt, wenn sich das Virus schnell vermehrt. Es ist jedoch besonders schwierig, freiwillige Probanden zu rekrutieren, die sich nicht in einem Krankenhaus befinden. Forscher müssen Menschen direkt nach dem positiven Test ausfindig machen und einen Weg finden, ihnen die Testmedikamente zu liefern.

An der University of Kentucky begannen Forscher im Mai mit einem solchen Versuch, ein Medikament namens Camostat zu testen, das normalerweise zur Behandlung von Entzündungen der Bauchspeicheldrüse verwendet wird. Die Wissenschaftler dachten, es könnte auch als antivirales Covid-19 wirken, da es ein Protein zerstört, von dem das Virus abhängt, um menschliche Zellen zu infizieren. Da Camostat eher in Pillenform als als Infusion erhältlich ist, wäre es besonders nützlich für Menschen wie die freiwilligen Probanden, von denen viele in abgelegenen ländlichen Gebieten lebten.

Aber die Forscher haben in den letzten acht Monaten versucht, genügend Teilnehmer zu rekrutieren. Sie hatten Probleme, Patienten zu finden, die kürzlich eine Covid-Diagnose erhalten haben, insbesondere mit dem unvorhersehbaren Anstieg und Abfall der Fälle.

“Dies war die Ursache für die Verzögerungen bei im Wesentlichen allen Studien auf der ganzen Welt”, sagte Dr. James Porterfield, ein Kliniker für Infektionskrankheiten am University of Kentucky College of Medicine. Wer leitet den Prozess?

Während Ärzte wie Dr. Porterfield Schwierigkeiten hatten, selbst Studien durchzuführen, sind einige Medikamente zu Sensationen geworden, die trotz fehlender Beweise als Allheilmittel gelobt werden.

Das erste vermeintliche Allheilmittel war Hydroxychloroquin, ein Medikament gegen Malaria. Fernsehexperten behaupteten, es habe Heilkräfte, ebenso wie Präsident Trump. Anstatt eine große, gut konzipierte Studie in vielen Krankenhäusern zu starten, begannen die Ärzte einen Schwarm kleiner Studien.

“Es gab keine Koordination und keine zentralisierte Führung”, sagte Ilan Schwartz, Experte für Infektionskrankheiten an der Universität von Alberta.

Trotzdem erteilte die FDA dem Medikament eine Notfallfreigabe zur Behandlung von Personen, die mit Covid ins Krankenhaus eingeliefert wurden. Als große klinische Studien endlich Ergebnisse lieferten, stellte sich heraus, dass das Medikament keinen Nutzen brachte – und sogar Schaden anrichten könnte. Die Agentur hat ihre Genehmigung im Juni zurückgezogen.

Viele Wissenschaftler waren verbittert und betrachteten all diese Arbeiten als Verschwendung wertvoller Zeit und Ressourcen.

“Die klare, eindeutige und überzeugende Lehre aus der Hydroxychloroquin-Geschichte für die medizinische Gemeinschaft und die Öffentlichkeit ist, dass Wissenschaft und Politik sich nicht vermischen”, schrieb Dr. Michael Saag von der Universität Alabama in Birmingham im November im New England Journal of Medicine.

Jetzt wird ein anderes Medikament populär, bevor es starke Beweise dafür gibt, dass es wirkt: die parasitentötende Verbindung Ivermectin. Senator Ron Johnson, Republikaner von Wisconsin, der im April Hydroxychloroquin pries, hielt im Dezember eine Anhörung ab, bei der Dr. Pierre Kory über Ivermectin aussagte. Dr. Kory, ein Lungen- und Intensivspezialist am Aurora St. Luke’s Medical Center in Milwaukee, nannte es “effektiv ein” Wundermittel “gegen Covid-19”. Es gibt jedoch keine veröffentlichten Ergebnisse aus groß angelegten klinischen Studien, die solche Behauptungen stützen, sondern nur kleine, suggestive.

Selbst wenn die Bundesregierung ein zentrales Versuchsnetzwerk eingerichtet hätte, wie es jetzt versucht wird, wären Wissenschaftler immer noch mit unvermeidlichen Hürden konfrontiert gewesen. Es braucht Zeit, um sorgfältige Experimente durchzuführen, um vielversprechende Medikamente zu entdecken und dann zu bestätigen, dass es sich wirklich lohnt, sie weiter zu untersuchen.

“In der Arzneimittelentwicklung sind wir an Landebahnen mit einer Laufzeit von 10 bis 15 Jahren gewöhnt”, sagte Sumit K. Chanda, Virologe am Sanford Burnham Prebys Medical Discovery Institute in La Jolla, Kalifornien.

Im Februar begannen Dr. Chanda und seine Kollegen eine andere Art der Suche nach einem Covid-19-Antivirusmittel. Sie untersuchten eine Bibliothek mit 13.000 Medikamenten und mischten jedes Medikament mit Zellen und Coronaviren, um festzustellen, ob sie Infektionen gestoppt hatten.

Ein paar Medikamente erwiesen sich als vielversprechend. Die Forscher testeten eine von ihnen – eine billige Lepra-Pille namens Clofazimin – über mehrere Monate und führten Experimente an menschlichem Lungengewebe und Hamstern durch. Clofazimin bekämpfte das Virus bei den Tieren, wenn sie es kurz nach der Infektion erhielten.

Jetzt, fast ein Jahr nach Beginn seiner Forschung, hofft Dr. Chanda, dass er den schwierigsten Teil der Drogentests finanzieren kann: große und randomisierte klinische Studien, die Millionen von Dollar kosten können. Um diese Phase effizient abzuschließen, benötigen Forscher fast immer die Unterstützung eines großen Unternehmens oder der Bundesregierung oder von beidem – wie dies bei den großen klinischen Studien für die neuen Coronavirus-Impfstoffe der Fall war.

Es ist unklar, wie die neuen Drogentestbemühungen der Biden-Regierung entscheiden werden, welche Medikamentenkandidaten unterstützt werden sollen. Wenn die Versuche jedoch in den nächsten Monaten beginnen, könnten sie möglicherweise bis Ende des Jahres nützliche Daten liefern.

Pharmaunternehmen beginnen auch, einige Studien mit wiederverwendeten Arzneimitteln zu finanzieren. Eine in dieser Woche in Science veröffentlichte Studie ergab, dass ein 24 Jahre altes Krebsmedikament namens Plitidepsin 27-mal wirksamer als Remdesivir ist, um das Coronavirus in Laborexperimenten zu stoppen. Im Oktober berichtete ein spanisches Pharmaunternehmen namens PharmaMar über vielversprechende Ergebnisse einer kleinen Sicherheitsstudie mit Plitidepsin. Jetzt bereitet sich das Unternehmen darauf vor, eine Spätstudie in Spanien zu starten, um festzustellen, ob das Medikament im Vergleich zu einem Placebo wirkt.

Der Pharmakonzern Merck führt eine große Studie im Spätstadium mit einer Pille namens Molnupiravir durch, die ursprünglich von Ridgeback Biotherapeutics gegen Influenza entwickelt wurde und nachweislich Frettchen von Covid-19 heilt. Die ersten Ergebnisse der Studie könnten bereits im März vorliegen.

Experten sind besonders gespannt auf diese Daten, da Molnupiravir möglicherweise mehr als nur Covid-19 behandelt. Im April fanden Wissenschaftler heraus, dass das Medikament auch Mäuse behandeln kann, die mit anderen Coronaviren infiziert sind, die SARS und MERS verursachen.

Alle Virostatika, die im Jahr 2021 auftauchen könnten, werden nicht das Leben retten, das Covid-19 bereits verloren hat. Es ist jedoch möglich, dass eines dieser Medikamente gegen künftige Coronavirus-Pandemien wirkt.
