US allows temporary protected status for people coming from Ebola-hit nations



WASHINGTON - The Department of Homeland Security will grant temporary protected status to people from the three West African countries most affected by Ebola who are currently residing in the United States, department officials said on Thursday.

People from Liberia, Guinea, and Sierra Leone arriving in the United States as of Thursday may apply for protection from deportation, as well as for work permits, for 18 months, said a Department of Homeland Security official.

After 18 months, the Secretary of Homeland Security will assess whether the protection should be extended, based on the level of the Ebola epidemic in West Africa.

The move is a response to the Ebola epidemic, which has claimed more than 5,000 lives, mostly in the three West African countries.

In order to prevent a mass migration from West Africa to the United States, nationals from these countries who arrive after Thursday will not be eligible for protected status.

US Citizenship and Immigration Services officials estimate that 8,000 people will be eligible to apply.

"The Ebola response in the United States has been front and center in the United States government at high levels," said a Department of Homeland Security official. "This designation has been part of that constant monitoring, reevaluation and reassessment of the appropriate response."

The United States reserves temporary protected status for people from countries experiencing conditions deemed too dangerous to return to, such as Haiti after the 2010 earthquake.

Unlike other recipients, protected people from West Africa will not be allowed to travel home and then return to the United States, in order to prevent the disease from spreading.

Nationals from the three countries must undergo a background check in order to receive protected status. Those with a criminal history will not be approved, said the Homeland Security official.

Ebola vaccine trials to start in Switzerland this week


GENEVA - Ebola vaccine trials are set to start in Switzerland this week after receiving the green light from the country's authorities, the World Health Organization said Tuesday.

Swiss regulators announced they would allow trials of an experimental vaccine made by Britain's GlaxoSmithKine, and tests on some 120 individuals were set to get under way at the CHUV hospital in Lausanne this week, the WHO said.

"This marks the latest step towards bringing safe and effective Ebola vaccines for testing and implementation as quickly as possible," the UN's health agency said in a statement.

There is no licensed treatment or vaccine for the deadly Ebola virus, which has killed nearly 5,000 people in the outbreak centred in west Africa.

The experimental GSK vaccine is one of two considered particularly promising by WHO.

Called ChAd3, it is based on a genetically modified chimpanzee adenovirus and trials have already begun in Mali, Britain and the United States, the WHO said.

"The trial will test the safety of the vaccine and its capacity to induce an immune response," it said.

It added that results of the trials in Switzerland and elsewhere will "provide the basis for planning subsequent trials involving several thousand participants, and for choosing vaccine dose-level for efficacy trials".

A second experimental vaccine being fast-tracked on the WHO's recommendation, Canadian-discovered rVSV, is set to soon start trials at the University Hospital of Geneva.

Trials of that potential vaccine have already begun in the United States and are also set to soon start in Germany, Gabon and Kenya.

"If shown to be safe and effective, either of the vaccines could be scaled up for production during the first quarter of next year, with millions of doses produced for wide distribution in high-risk countries," WHO assistant director general Marie-Paule Kieny said in the statement.

Some US hospitals weigh withholding care to Ebola patients


CHICAGO/NEW YORK - The Ebola crisis is forcing the American healthcare system to consider the previously unthinkable: withholding some medical interventions because they are too dangerous to doctors and nurses and unlikely to help a patient.

US hospitals have over the years come under criticism for undertaking measures that prolong dying rather than improve patients' quality of life.

But the care of the first Ebola patient diagnosed in the United States, who received dialysis and intubation and infected two nurses caring for him, is spurring hospitals and medical associations to develop the first guidelines for what can reasonably be done and what should be withheld.

Officials from at least three hospital systems interviewed by Reuters said they were considering whether to withhold individual procedures or leave it up to individual doctors to determine whether an intervention would be performed.

Ethics experts say they are also fielding more calls from doctors asking what their professional obligations are to patients if healthcare workers could be at risk.

US health officials meanwhile are trying to establish a network of about 20 hospitals nationwide that would be fully equipped to handle all aspects of Ebola care.

Their concern is that poorly trained or poorly equipped hospitals that perform invasive procedures will expose staff to bodily fluids of a patient when they are most infectious. The US Centers for Disease Control and Prevention is working with kidney specialists on clinical guidelines for delivering dialysis to Ebola patients. The recommendations could come as early as this week.  

The possibility of withholding care represents a departure from the "do everything" philosophy in most American hospitals and a return to a view that held sway a century ago, when doctors were at greater risk of becoming infected by treating dying patients.

"This is another example of how this 21st century viral threat has pulled us back into the 19th century," said medical historian Dr. Howard Markel of the University of Michigan.  

Some ethicists and physicians take issue with the shift.

Because the world has almost no experience treating Ebola patients in state-of-the-art facilities rather than the rudimentary ones in Africa, there are no reliable data on when someone truly is beyond help, whether dialysis can make the difference between life and death, or even whether cardiopulmonary resuscitation (CPR) can be done safely with proper protective equipment and protocols.

Such procedures "may have diminishing effectiveness as the severity of the disease increases, but we simply have no data on that," said Dr. G. Kevin Donovan, director of the bioethics center at Georgetown University.

Donovan said he had received inquiries from fellow physicians about whether hospitals should draw up lists of procedures that would not be performed on an Ebola patient. "To have a blanket refusal to offer these procedures is not ethically acceptable,” he said he told the doctors.

New guidelines

Nevertheless, discussions about adopting policies to withhold care in Ebola cases are under way at places like Geisinger Health System, which operates hospitals in Pennsylvania, and Intermountain Healthcare, which runs facilities in Utah, according to their spokesmen.

Dr Nancy Kass, a bioethicist at Johns Hopkins Bloomberg School of Public Health, said healthcare workers should not hesitate to perform a medically necessary procedure so long as they have robust personal protective gear.

So far, only two US hospitals have used kidney dialysis: Texas Health Presbyterian Dallas, which treated Liberian patient Thomas Duncan and where two nurses became infected, and Emory University Hospital in Atlanta, which has treated four Ebola patients at its biocontainment unit without any healthcare workers becoming infected.

Although it is not yet clear how the Dallas nurses became infected, health officials have questioned both the lack of adequate training in the use of protective gear and the decision to perform invasive procedures.

The American Society of Nephrology and CDC are now working on new dialysis guidelines for Ebola patients, whose kidneys often fail. In some cases, dialysis can help a patient get through the worst of the illness until their own immune system can fend off the virus.

Nephrologist Dr. Harold Franch said the new guidelines will consider both whether the procedure is medically necessary and whether the hospital can do it safely.

"Most academic medical centers and many good private tertiary care hospitals will be able to do this," he said. Yet he thinks many hospitals may not offer the service, since “it takes a lot of money and time to train people.”

Treat, or flee? 


Throughout the history of medicine some doctors have declined to treat infectious patients or fled epidemics, said Michigan's Markel. Greek physician and philosopher Galen fled Rome during the bubonic plague 1,800 years ago, doctors deserted European cities stricken by the Black Death of the Middle Ages, and some health workers refused to treat HIV/AIDS patients in the 1980s.

"The idea that a doctor would stick to his post to the last during an epidemic, that's not part of the Hippocratic Oath," Markel said. "If you feel your life is at risk you don't have to stay and provide care."

At University of Chicago Medicine, questions of taking last-ditch measures were discussed early in the hospital's Ebola planning, said Dr. Emily Landon, a bioethicist and epidemiologist.

Decisions about offering services such as dialysis or inserting a breathing tube are made in advance by the hospital's care team in consultation with patients. But if a doctor on the team feels in the moment that she cannot provide the service, another may step in and do the procedure.

Landon views dialysis as a "no brainer" for Ebola patients, and believes the risks are fairly low to the well-trained nursing staff who have volunteered for the hospital's isolation ward.

But putting in a breathing tube and putting them on a ventilator is more controversial.

"We have very little experience with that except for Mr Duncan, who didn't do well," she said. The hospital plans to consult with patients before the need arises and plans to insert a breathing tube at the earliest sign that it might be needed.

CPR, which is performed when a patient's breathing or heart stops, also poses risks. It can involve chest compressions, inserting breathing tubes and other invasive procedures.

If a patient goes into cardiac or respiratory arrest, a team would have to don protective gear. Rushing could leave them without proper protection, but a delay could make the procedure ineffective.

That represents too great a risk for caregivers for what could be "a futile act," said Dr. Joseph Fins, chief of medical ethics at Weill Cornell Medical College in New York City.
