Blood test detects positive COVID-19 result in 20 minutes

Melbourne, Australia - World-first research by Monash University in Australia has been able to detect positive COVID- 19 cases using blood samples in about 20 minutes, and identify whether someone has contracted the virus. In a discovery that could advance the worldwide effort to limit the community spread of COVID-19 through robust contact tracing, researchers were able to identify recent COVID-19 cases using 25 microlitres of plasma from blood samples. The research team, led by BioPRIA and Monash University's Chemical Engineering Department, including researchers from the ARC Center of Excellence in Convergent BioNano Science and Technology (CBNS), developed a simple agglutination assay—an analysis to determine the presence and amount of a substance in blood—to detect the presence of antibodies raised in response to the SARS-CoV-2 infection. Positive COVID-19 cases caused an agglutination or a clustering of red blood cells, which was easily identifiable to the naked eye. Researchers were able to retrieve positive or negative readings in about 20 minutes. While the current swab / PCR tests are used to identify people who are currently positive with COVID-19, the agglutination assay can determine whether someone had been recently infected once the infection is resolved—and could potentially be used to detect antibodies raised in response to vaccination to aid clinical trials. Using a simple lab setup, this discovery could see medical practitioners across the world testing up to 200 blood samples an hour. At some hospitals with high-grade diagnostic machines, more than 700 blood samples could be tested hourly—about 16,800 each day. Study findings could help high-risk countries with population screening, case identification, contact tracing, confirming vaccine efficacy during clinical trials, and vaccine distribution. This world-first research was published today (Friday 17 July 2020) in the prestigious journal ACS Sensors. A patent for the innovation has been filed and researchers are seeking commercial and government support to upscale production. Dr. Simon Corrie, Professor Gil Garnier and Professor Mark Banaszak Holl (BioPRIA and Chemical Engineering, Monash University), and Associate Professor Timothy Scott (BioPRIA, Chemical Engineering and Materials Science and Engineering, Monash University) led the study, with initial funding provided by the Chemical Engineering Department and the Monash Center to Impact Anti-microbial Resistance. Dr. Corrie, Senior Lecturer in Chemical Engineering at Monash University and Chief Investigator in the CBNS, said the findings were exciting for governments and health care teams across the world in the race to stop the spread of COVID-19. He said this practice has the potential to become upscaled immediately for serological testing. "Detection of antibodies in patient plasma or serum involves pipetting a mixture of reagent red blood cells (RRBCs) and antibody-containing serum/plasma onto a gel card containing separation media, incubating the card for 5-15 minutes, and using a centrifuge to separate agglutinated cells from free cells," Dr. Corrie said. "This simple assay, based on commonly used blood typing infrastructure and already manufactured at scale, can be rolled out rapidly across Australia and beyond. This test can be used in any lab that has blood typing infrastructure, which is extremely common across the world." Researchers collaborated with clinicians at Monash Health to collect blood samples from people recently infected with COVID-19, as well as samples from healthy individuals sourced before the pandemic emerged. Tests on 10 clinical blood samples involved incubating patient plasma or serum with red blood cells previously coated with short peptides representing pieces of the SARS-CoV-2 virus. If the patient sample contained antibodies against SARS-CoV-2, these antibodies would bind to peptides and result in aggregation of the red blood cells. Researchers then used gel cards to separate aggregated cells from free cells, in order to see a line of aggregated cells indicating a positive response. In negative samples, no aggregates in the gel cards were observed. "We found that by producing bioconjugates of anti-D-IgG and peptides from SARS-CoV-2 spike protein, and immobilizing these to RRBCs, selective agglutination in gel cards was observed in the plasma collected from patients recently infected with SARS-CoV-2 in comparison to healthy plasma and negative controls," Professor Gil Garnier, Director of BioPRIA, said. "Importantly, negative control reactions involving either SARS-CoV-2-negative samples, or RRBCs and SARS-CoV-2-positive samples without bioconjugates, all revealed no agglutination behavior." Professor Banaszak Holl, Head of Chemical Engineering at Monash University, commended the work of talented Ph.D. students in BioPRIA and Chemical Engineering who paused their projects to help deliver this game changing COVID-19 test. "This simple, rapid, and easily scalable approach has immediate application in SARS-CoV-2 serological testing, and is a useful platform for assay development beyond the COVID-19 pandemic. We are indebted to the work of our Ph.D. students in bringing this to life," Professor Banaszak Holl said. "Funding is required in order to perform full clinical evaluation across many samples and sites. With commercial support, we can begin to manufacture and roll out this assay to the communities that need it. This can take as little as six months depending on the support we receive."

The U.S. hits 4 million cases Of coronavirus

Washington, DC - Last week the United States exceeded 4 million reported Covid-19 cases, according to the Johns Hopkins coronavirus tracker. One million of these were reported in the last two weeks and outbreaks continue to result in record case numbers in several states. Over 1,000 Americans died yesterday from the disease, leaving many people asking “What can be done now?” to try and stem the pandemic. “Slowing the spread is not a mystery,” said Rebecca Katz, Professor and Director of the Center for Global Health Science and Security at Georgetown University. “We know it is a combination of individuals taking appropriate precautions (masks, physical distance, hand hygiene, avoiding crowded locations) and having sufficient capacity to test, trace and isolate,” she added. “It’s not an easy decision, but many of these states need to move to more aggressive efforts to limit person-to-person contact,” said Steven A. Pergam, MD, MPH Associate Professor, Vaccine and Infectious Diseases Division, Fred Hutchinson Cancer Research Center. “The virus thrives on humans being close together and to date what has been most effective at controlling spread is policies targeting gatherings in public places. More restrictive “shelter at home” orders are likely the most effective, but major local efforts to limit even small gatherings is the key. This, coupled with masking of those who cannot physically distance, limits opportunities for the virus to spread and can help slow community transmission,” he added. “They need a full on enforced lock down ASAP to get things under control,” said David Fisman, Professor of Epidemiology at University of Toronto in Canada and a practicing internist.”The difficulty is that lock down won't stop transmissions that have already happened so would expect ongoing increases in hospitalizations for 2-3 weeks even after lock down as that's the amount of time it takes for those transmissions to become cases, and those cases to get sick enough for hospitalization and intensive care,” he added. “That’s tough and a tie between state-wide masking mandates and efforts to ensure adequate testing is available,” said Saskia Popescu, an infectious disease epidemiologist and Professor at the University of Arizona College of Public Health. “This includes drive through options, free testing sites, and ultimately the capacity to rapidly perform the tests and relay the results. A delay in testing means that people are forced to isolate longer assuming they have the virus, but it also delays reporting and contact tracing. This needs to be followed by ensuring hospitals and public health departments have the resources they need to avoid being over-stressed and healthcare workers have the critical resources needed to treat patients safely. Lastly, we need more public communication campaigns about risk awareness and the importuning of masking/social distancing,” she added. “Based on international experience, for example in Hong Kong, the following measures would likely make most difference (short of a full stay-at-home order): Close bars, restaurants and gyms. Switch to working from home as much as possible. Stop indoor gatherings between different households,” said Adam Kucharski, Associate Professor at the London School of Hygiene & Tropical Medicine in the U.K. Many states are experiencing significant outbreaks – do you think that these are likely to spread to all/most U.S. states or can individual states potentially curb the spread? “People move across state borders. If we have outbreaks in one part of the country, we must be prepared for transmission to other parts of the country. This is why continued vigilance is critical,” said Katz. “It seems likely that travel between states is going to lead to recurrent clusters in states that have controlled transmission. For example, what is going on in Florida may eventually affect New York or other cities throughout the country. This is particularly true if outbreaks cannot be controlled. I just imagine how many people from all over the U.S. will visit Disney World over the next few weeks,” said Pergam. “In states with disease under control can do cautious opening with adherence to the Japanese C's (avoid close, closed, crowded) and mask mandates. This has worked elsewhere and there's no reason it shouldn't in the U.S. Need to test widely as this is a sneaky disease, and you don't want to be recognizing spread only with super-spreader events,” said Fisman. “It’s very likely at this point and the politicization of the pandemic hasn’t helped. Other states and prepare their health and public health systems, but also ensure they can scale up testing and response mechanisms,” said Popescu. “Contact tracing alone is unlikely to be enough to stop large outbreaks, but scaled up testing - particularly in high risk groups like healthcare works, care home staff, key workers in shops - could help identify infections and prevent chains of transmission, working in tandem with wider social distancing measures,” said Kucharski. Some people have suggested that mitigation strategies proposed several months ago such as contact tracing and accessible testing are no longer adequate to contain outbreaks in badly affected states. What are your thoughts on this?“You need to have the combination of strategies. People need to do their part. You also don't give up on testing, tracing and isolation. But when you have widespread community transmission, you may also need to put more restrictive policies in place,” said Katz. “Testing and contact tracing remain critical pillars of prevention, but in some of these large urban centers, the public health infrastructure are overwhelmed and won’t keep up with the sheer number of cases. This is exacerbated by major cutbacks in county and state public health programs. However, cities like New York city show it can be done even in the midst of a large pandemic – it takes investment,” said Pergam. “Mitigation in these situations really shifts to structures and policies which assure more physical distancing in the community – keeping people at home. Universal masking can help decrease exposure risk, and targeted prevention specifically targeting high-risk setting like nursing homes and prisons, can save lives. Finally, all good public health policy involves communication and community education about prevention,” Pergam added. “Those efforts definitely become strained the bigger the outbreak and the fewer their resources, which means we need to be able to flex and scale up their capacities. That shouldn’t be seen as an indicator for giving up though,” said Popescu. “Contact tracing is meaningless when you have a massive number of cases...it'll simply overstretch and wear down and already overextended public health workforce,” said Fisman. “It may be a helpful intervention when cases are knocked down to low levels and you're preventing resurgences,” he added.

Aerosols are a bigger coronavirus threat than WHO guidelines suggest

Geneva, Switzerland - When someone coughs, talks or even breathes, they send tiny respiratory droplets into the surrounding air. The smallest of these droplets can float for hours, and there is strong evidence that they can carry live coronavirus if the person is infected. The risk from these aerosols isn’t currently incorporated into the World Health Organization’s formal guidance for nations, though. The WHO suggests that the coronavirus is primarily transmitted by coughing or sneezing large droplets into someone’s face, not a longer-term threat that can be floating in the air. After pressure from scientists, that may soon change. This week, more than 200 scientists published an open letter to the WHO warning about airborne transmission of COVID-19 via aerosols and urging the organization to recognize the risks. The WHO has since acknowledged growing evidence of airborne spread of the disease, but it has not yet changed its advice to protect people from contracting COVID-19 from aerosols. As professors who study fluid dynamics and aerosols, we believe it is important for people to understand the risks and what they can do to protect themselves. Aerosols are particles that are suspended in the air. When humans breathe, talk, sing, cough or sneeze, the emitted respiratory droplets mix in the surrounding air and form an aerosol. Because larger droplets quickly fall to the ground, respiratory aerosols are often described as being made up of smaller droplets that are less than 5 microns, or about one tenth the width of a human hair. In general, droplets form as a sheet of liquid breaks apart. You’ve probably experienced this phenomenon by blowing soap bubbles. Sometimes the bubble doesn’t fully form, but instead breaks apart into many droplets. Similarly, in humans, small sheets and strands of liquid – mucus – often stretch across portions of the airway. This most often occurs in locations where the airway opens and closes again and again. That happens deep within the lungs as the bronchioles and alveolar sacs expand and contract during breathing, within the larynx as the vocal folds vibrate during speech, or at the mouth, as the tongue and lips move while talking. The airflow produced by breathing, speaking and coughing breaks apart these sheets of mucus, just like blowing the soap bubble. The size of the droplets varies based on how and where they are produced within the airway. While coughing generates the largest quantity of droplets, research has shown that just two to three minutes of talking can produce as many droplets as one cough. Droplets that are smaller than 5 microns can remain suspended in the air for many minutes to hours because the effect of air drag relative to gravity is large. In addition, the water content of virus-carrying droplets evaporates while they are airborne, decreasing their size. Even if most of the fluid evaporates from a virus-laden droplet, the droplet does not disappear; it just becomes smaller, and the smaller the droplet, the longer it will stay suspended in the air. Because smaller diameter droplets are more efficient at penetrating deep into the pulmonary system, they also pose a much greater infection risk. The WHO guidelines suggested that the virus RNA found in small droplets wasn’t viable in most circumstances. However, early research on the SARS-CoV-2 virus has shown that it is viable as an aerosol for up to 3 hours.

Misericordia hospital adopts 'aggressive' protocols in bid to control COVID-19 outbreak

Edmonton, AB -  A growing outbreak of COVID-19 has forced the Misericordia Community Hospital to close its doors to most new patients and institute a series of "aggressive" pandemic protocols in bid to slow the spread of the virus.  As of Monday morning, 18 patients and 14 staff at the west-Edmonton hospital have tested positive for coronavirus, Alberta Health Services and Covenant Health said in a joint statement.  Eight new cases, including seven patients and one staff member, were identified over the weekend. As of Friday, 11 patients and 13 staff had tested positive for COVID-19. Two patients have died. The first death was confirmed on June 25. AHS officials became aware of the second patient death on July 4, Dr. David Zygun, Edmonton zone medical director with AHS, said Monday. The second death was a man in his 70s. The outbreak at the Misericordia began on June 20, Zygun said. Health Minister Tyler Shandro said the province is monitoring the situation closely.  "This is an evolving situation, and it has been evolving over the last 48 hours or so," Shandro said. "Testing is going on to be able to do the tracing and contain the outbreak. AHS is working with Covenant [Health], and our public health officials are working with them as well, to make sure the infection prevention and control measures are in place at the Misericordia to make sure that the patients and the staff are protected. "Obviously, I'm very concerned and have been, as this situation has been evolving over the last couple of days." Dr. David Zygun, Edmonton zone medical director with AHS, warned Monday that the outbreak at the Misericordia is "an evolving situation." (David Bajer/CBC) Patients who have tested positive are being cared for together on three units, including the hospital's designated COVID-19 unit. In all, eight units are now included in the outbreak restrictions as a necessary precaution. "AHS and Covenant Health officials have implemented aggressive outbreak protocols and are undertaking widespread testing and contact tracing of any potentially exposed patients and staff," Dr. Marcia Johnson, deputy chief medical officer of health said in the statement. "Health officials are working around the clock to prevent further spread of this virus, protect the health and well-being of patients, staff and physicians, and bring a timely and safe resolution to this outbreak." Hospital closed to new admissions To reduce the risk of further transmission, AHS said the hospital is now closed to new admissions and transfers for surgical and medical patients. The emergency department remains open. But paramedics will take patients to other Edmonton hospitals, except in emergencies where the hospital is the nearest acute care site, AHS said. Surgical capacity will be restricted to day surgery. Overnight surgeries will be postponed or completed at another site in the Edmonton area.

CDC and drug-makers boost flu vaccine doses for upcoming season

Atlanta, GA - Experts are girding for coronavirus and influenza hitting at the same time Worried about a simultaneous assault of the novel coronavirus and seasonal influenza this winter, public health officials and vaccine manufacturers are making millions of extra flu vaccine doses to protect those most vulnerable to the pandemic and influenza, according to government and company officials. Even though flu season doesn’t begin until the fall, major flu vaccine manufacturers say they plan to boost production by about 10 percent, to about 189 million doses, up from 170 million doses last year, to ensure enough doses exist for an anticipated surge in people seeking flu shots. The Centers for Disease Control and Prevention has taken the rare step of buying 7 million doses directly from manufacturers to be distributed to states for adult vaccination, CDC Director Robert Redfield said in an interview. “This is a big move,” he said. That’s about 14 times the 500,000 doses the agency typically purchases for adults. The adult doses are included in the industry’s total planned production. Getting a flu shot does not protect against the coronavirus, but disease experts said reducing episodes of flu could prove pivotal in freeing up space in hospitals and medical offices to deal with covid-19, the disease caused by the coronavirus. Even as President Trump and other White House officials downplay the pandemic threat this fall, the flu preparations underscore the alarm among public health officials, clinicians, advocacy groups and industry executives about the additional threat from the coronavirus. The unprecedented convergence of two highly contagious respiratory viruses could happen in the winter, with each pathogen causing life-threatening illness and death. Health officials are especially concerned about people at higher risk for both the coronavirus and influenza, including residents and employees at long-term care facilities, African Americans, Hispanics, and people with underlying medical conditions. Typically, fewer than half of Americans get a flu shot each season. Vaccination rates for blacks and Hispanics have traditionally been lower. Slightly more than a third of black and Hispanic adults get vaccinated, according to CDC data. The CDC recommends the vaccine for everyone over age 6 months. It’s unclear whether the possible double whammy of the coronavirus and influenza will push more Americans to get a flu vaccine. Almost nothing is known about the interaction between the coronavirus and influenza, experts say. It is possible for someone to be infected with the coronavirus and influenza at the same time, but experts have very little data. There is no coronavirus vaccine and only limited treatment for covid-19. But even a moderately effective flu vaccine reduces the severity of flu-related illness and keeps people out of the hospital, officials have said. “We want to take flu off the table, in every way possible, make flu a non-factor,” said LJ Tan, chief strategy officer of the Immunization Action Coalition. At the advocacy group’s annual flu summit in May, manufacturers who supply vaccine disclosed their plan to boost production by 10 percent for the upcoming flu season. At a House hearing this week, lawmakers asked top health officials what the government needed to do to prepare for the coronavirus in the fall. Among the items Assistant Secretary for Health Brett Giroir identified was “enough flu vaccine to get everybody vaccinated this winter.” He added: “That’s one less virus that could kill 20, 30, 50,000, 70,000 [people] and potentially even be a co-infection with covid.” The CDC’s purchase of additional doses for adults is “certainly unprecedented in recent memory,” Nancy Messonnier, director of CDC’s National Center for Immunization and Respiratory Diseases, said in an interview. CDC spent $100 million to buy the adult doses, officials said. An initial CDC request to spend $700 million to buy 50 million doses for adults was turned down by administration officials, according to federal health officials who spoke on the condition of anonymity to discuss policy deliberations. Some immunization advocates are pushing the government to tap pandemic-related emergency funds to buy additional adult doses. A small fraction of that money could be used to “ramp up dosage levels to anticipate what we think demand will be this fall,” said former Senate majority leader Tom Daschle, who heads the recently formed Coalition to Stop Flu. The group includes immunization advocates, state and local health organizations, the American Heart Association, and vaccine manufacturers. If the U.S. government secures additional funding by mid-July, flu manufacturers in the coalition said they would be able to fulfill additional orders for later in the flu season, Daschle said. Influenza viruses change year to year, so vaccines must be updated annually. But tight production deadlines mean that manufacturers need to know within weeks how many total doses they need to produce. Officials at Sanofi Pasteur and Seqirus, which have committed to producing 75 million and 55 million doses, respectively, said they have received an increase in preorders from customers, including retailers and health-care systems. “This is a flu season like we’ve never seen before,” said David Ross, vice president of commercial operations for North America at Seqirus. The company has already adjusted manufacturing capacity to address the increase in demand, he said. “We’ll continue to explore opportunities to manufacture more vaccine if demand requires it,” Ross said. Flu vaccine effectiveness varies by season. Officials pick the flu strains that the vaccine will target months ahead of the flu season, meaning the vaccine isn’t always a good match for the strains that wind up circulating. When the vaccine is similar to circulating flu viruses, vaccinations have been shown to reduce the risk of having to go to the doctor by 40 percent to 60 percent. The overall effectiveness of last year’s vaccine was 39 percent, according to CDC data released Wednesday. Health officials are also grappling with another big challenge this fall: making sure people can get vaccinated safely, free from exposure to the coronavirus. The CDC has given $140 million to immunization programs across the United States to boost adult flu vaccination. The agency is working with state health departments, pharmacies and other health-care providers to develop curbside and drive-through flu clinics and other alternatives for people to get vaccinated. The CDC has also developed a new test that can simultaneously detect the novel coronavirus and the influenza virus, and is seeking emergency use authorization from the Food and Drug Administration. Getting the right public health message out will also be critical. Older adults, blacks and Hispanics are among the groups who need to be prioritized for flu vaccination, said Michael Greenberg, head of medical operations for Sanofi Pasteur in North America. But if stay-at-home orders are in place because of the pandemic, these are the same people who are told to avoid leaving their homes. “It’s a very delicate communication,” Greenberg said. “You need to instill confidence, and at the same time, stress the need to get vaccinated.”

Too soon to call dexamethasone a COVID-19 breakthrough

London, UK - Not long after researchers in England said the low-cost steroid dexamethasone reduced deaths among hospitalized COVID-19 patients, health experts around the world started raising alarm bells about the study—and the extreme enthusiasm it generated. Researchers funded by the U.K. government said dexamethasone lowered the risk of death in COVID-19 patients on ventilators or oxygen by 35% and 20%, respectively. But they only released a summary of the data, rather than the full study. That irked some high-profile doctors, particularly in the wake of hydroxychloroquine's dramatic rise and fall. “It will be great news if dexamethasone, a cheap steroid, really does cut deaths by one-third in ventilated patients with COVID-19, but after all the retractions and walk-backs, it is unacceptable to tout study results by press release without releasing the paper,” said Atul Gawande, M.D., author and former CEO of healthcare venture Haven, on Twitter. In England, the top-line results were enough to convince the National Health Service (NHS) to approve dexamethasone for use in all COVID-19 patients requiring ventilation. And the World Health Organization vowed to update its clinical guidance on treating the coronavirus to incorporate the new data on the steroid. But those endorsements of dexamethasone came on the heels of perhaps the most extraordinary of the COVID-19 walk-backs: the FDA’s retraction of its emergency use authorization for hydroxychloroquine in COVID-19. The agency pulled its approval of the malaria drug, which had been loudly endorsed by President Donald Trump, after controlled studies revealed it provided no benefit to patients. The hydroxychloroquine debacle was clearly on the mind of Hilary Jones, a well-known physician and TV commentator in Britain. He urged viewers in an on-air interview Wednesday not to “go rushing to the shop asking for dexamethasone,” which, like hydroxychloroquine, is a decades-old drug that’s inexpensive. However, “it’s not a preventative,” he said. What’s more, Jones pointed out, “the death rate even with dexamethasone is still 28%. So, it’s still massively high; this is still a very nasty virus.” The clinical trial, he added, will need to “show real benefit over risk.” One well-known problem with steroids is that they can suppress the immune system, which could complicate the recovery process for any virus. That concern was voiced to Reuters by Thomas McGinn, M.D., deputy physician-in-chief at Northwell Health. He said he wouldn’t recommend the use of dexamethasone to treat COVID-19 without seeing the full results of the U.K. study published in a peer-reviewed journal—a sentiment echoed by physicians at the University of Washington and Massachusetts General Hospital. The U.K. trial of dexamethasone, called Recovery, enrolled more than 11,500 patients at 175 NHS hospitals. The researchers are “working to publish the full details” of the study as soon as possible, according to a statement.

Moderna to start in July what could be first late-stage coronavirus vaccine trial

Norwood, MA - From the outset of coronavirus' spread around the world, Moderna has been a frontrunner in designing, constructing and putting into testing a vaccine for the virus, which has now infected more than 7 million people globally.  The Phase 3 study plans announced Thursday would keep Moderna at the forefront, and are the first to be detailed for any vaccine candidate. The roughly 30,000-participant trial would be co-run by the National Institute of Allergy and Infectious Diseases, the agency that led the Phase 1 study of Moderna's vaccine, dubbed mRNA-1273. Study volunteers would be randomized to receive either placebo or mRNA-1273, with an equal chance of getting either. Notably, the study's main goal won't be whether the vaccine prevents infection altogether, but rather whether mRNA-1273 stops people from developing COVID-19. Moderna will use a 100 microgram dose of its vaccine, the higher of two doses now being tested in an ongoing Phase 2 trial. The company hopes that dose will maximize the sought-after immune response, while still being safe. In the NIAID-run Phase 1 trial, volunteers given the 100 mg dose experienced mostly mild injection site reactions, while some people in a third, higher dose initially tested had severe fever-like symptoms. But choosing the 100 mg dose will come at a cost. When Moderna signed a manufacturing deal with Swiss firm Lonza, it projected being able to make 1 billion doses each year, assuming a 50 mg dose. With the 100 mg dose now selected, Moderna said it and Lonza could make 500 million doses per year, and "possibly" up to 1 billion by next year. So far, only snippets of data are available for Moderna's vaccine. Summary results released in a statement by the company indicated eight participants in the Phase 1 trial produced antibodies capable of neutralizing the coronavirus in test tubes. It's unclear, however, how meaningful the immune response the vaccine produces is and how long it will last. The NIH is submitting the results from that initial study to a peer-reviewed medical journal, Moderna said Thursday. More answers could come from the Phase 2 study currently underway. Moderna has fully enrolled a 300-participant group of adults between 18 and 54 years old, as well as a smaller 50-volunteer "sentinel" group of older adults that's meant to evaluate the vaccine's safety in a frailer population. Participants are receiving two shots of the 50 mg or 100 mg dose, or placebo. They'll be monitored for a year after the second vaccination. Though Moderna is the first to detail a late-stage study, others should soon follow. The Wall Street Journal, citing an NIH researcher, reported earlier this week that AstraZeneca could start a Phase 3 trial of its vaccine in August, and J&J could follow in September. For J&J, a target date of September is an acceleration of several months from its original plans, which had set September as the initial start of human testing. Now, J&J expects to begin a Phase 1 trial in the U.S. and Belgium sometime in the second half of July.

Lancet retracts major Covid-19 paper that raised safety concerns about malaria drugs

London, UK - The Lancet, one of the world’s top medical journals, recently retracted an influential study that raised alarms about the safety of the experimental Covid-19 treatments chloroquine and hydroxychloroquine amid scrutiny of the data underlying the paper. Just over an hour later, the New England Journal of Medicine retracted a separate study, focused on blood pressure medications in Covid-19, that relied on data from the same company. The retractions came at the request of the authors of the studies, published last month, who were not directly involved with the data collection and sources, the journals said. “We can no longer vouch for the veracity of the primary data sources,” Mandeep Mehra of Brigham and Women’s Hospital, Frank Ruschitzka of University Hospital Zurich, and Amit Patel of University of Utah said in a statement issued by the Lancet. “Due to this unfortunate development, the authors request that the paper be retracted.” The retraction of the Lancet paper is sure to add fuel to contentious arguments about the potential of chloroquine and hydroxychloroquine, two old malaria drugs, in Covid-19, the disease caused by the novel coronavirus. President Trump has touted them as valuable treatments, despite a lack of rigorous data showing they have a benefit. Meanwhile, on Wednesday, researchers reported the results of the first gold-standard clinical trial of hydroxycholoroquine in Covid-19, concluding that it did not prevent infections any better than placebo. Other clinical trials, including some looking at the drugs as treatments, are ongoing. The Lancet study gained so much attention because it went further than other observational studies that had similarly found the drugs were not associated with improved outcomes for patients. The study, which was purportedly based on patient data from 671 hospitals on six continents, reported the drugs also corresponded to higher mortality. The findings led to the pause of some global clinical trials studying hydroxychloroquine so researchers could check for any safety concerns. Outside experts, however, quickly raised concerns after noticing inconsistencies in the data. They asked the company that compiled and analyzed the data, Surgisphere, to explain how it sourced its data. As scrutiny grew, the authors on the paper not affiliated with Surgisphere called for an independent audit. In their Lancet statement Thursday, they said that Surgisphere was not cooperating with the independent reviewers and would not provide the data. “As such, our reviewers were not able to conduct an independent and private peer review and therefore notified us of their withdrawal from the peer-review process,” the researchers wrote.

Coronavirus antibody tests mired in controversy

Atlanta, GA - In a news report recently published by WebMD, big-name medical testing companies like Quest Diagnostics and LabCorp have expanded access to antibody tests that can tell whether someone was recently infected with the coronavirus a few weeks after they’ve recovered from disease. In the US you can order these tests online or go through your doctor. Public health experts, however, question the value of antibody testing for individuals given the tests’ limitations and whether results are meaningful. The CDC said this week that antibody tests are not yet accurate or reliable enough to use to determine whether to reopen workplaces, schools, and other places where people gather. The accuracy of antibody tests has been mired in controversy. The FDA allowed hundreds of tests onto the market resulting in a Congressional investigation last month. Reports then surfaced last week that the CDC and states have been combining the number of antibody tests performed with the number of viral tests, further adding to the confusion about interpreting test results. Researchers do not know yet if the antibodies that result from SARS-CoV-2 infection will provide someone with immunity from reinfection. If antibodies do provide immunity, experts don’t know how much antibody it takes to provide protection or how long protection might last. “We’ve already measured the antibodies in many people, so we know that an immune response is there. We just have to get better, more nuanced information about what those responses mean and how to interpret them,” Michael Mina, MD, PhD, assistant professor of epidemiology at the Harvard T.H. Chan School of Public Health, said on a May 4 media call. But the most accurate tests may not be able to correctly identify each person who has antibodies. Even commercial tests that report 100% accuracy may still produce false-positives when enough samples are run, says Andrew Azman, PhD, assistant scientist in the Department of Epidemiology at Johns Hopkins University Bloomberg School of Public Health. Given the uncertainty, it’s premature to issue “immune passports,” Mina, Azman, and other infectious disease and public health experts wrote in a May 19 editorial in Science Immunology. This concept assumes that when someone tests positive to an antibody test, there is a good chance of avoiding re-infection or transmitting the virus to others. But it can give people a sense of false security, warns Azman. Some employers are using antibody tests, also known as serological tests, to decide which employees may return to work or work on the frontlines. But “until we have more evidence, serological tests alone should not be used to make decisions such as when staff can return to work, the need for personal protective equipment or the need to discontinue social distancing measures,” the Association of Public Health Laboratories (APHL) said in a joint statement with the Council of State and Territorial Epidemiologists (CSTE) this month. The CDC said the same thing this week in updated guidance on its website.

In the Anti-Vaxxer Era, Will Countries Make a Coronavirus Vaccine Mandatory?

Calgary, AB - In 2019, the World Health Organization listed vaccine hesitancy as one of the ten gravest threats to global health. Now, public health agencies are trying to figure out what to do next. After months of isolating from friends and family, it seems like most people are desperately hoping for a COVID-19 vaccine that’ll put an end to the pandemic. But in an era of misinformation and lockdown protests, often touted by anti-vaxxers, there’s an open question on how much uptake there will be for the vaccine, should one arrive. And that leads to a second question: should governments consider making a COVID-19 vaccine mandatory? “Making vaccines mandatory is the last tool in the toolkit of public health,” said Lynora Saxinger, a professor with the University of Alberta department of medical microbiology and immunology. Vaccination rates for most diseases are quite high, which suggests public health agencies won’t have to force people to take a COVID-19 vaccine, Saxinger said. For example, according to the World Health Organization (WHO), as of 2018, an estimated 84 percent of the global population was immunized for Hepatitis B; about 86 percent of children received a measles vaccine before their second birthday; and 84 percent of infants were immunized for polio. (Rates tend to be higher in North America and Europe than elsewhere largely due to unequal access.) But there's been a lot of misinformation spreading about the coronavirus, Saxinger said, so she’s worried it could sway Canadians away from vaccines. Both Saxinger and another expert told VICE they’re particularly worried about people who don’t identify as anti-vaxxers, but express hesitancy when considering vaccinations, because they’re likely more susceptible to misinformation. Last week, Alberta Premier Jason Kenney said he has no intention of making a COVID-19 vaccine mandatory. However, if a safe and effective vaccine is found, the government will “strongly encourage people to use it as we do in flu season" Kenney said. Laval University medical anthropologist, Ève Dubé, said she’s noticed a lot of people express “a perception that the government will force people to get vaccinated.” “These are rumours...it’s really unlikely,” she said. According to Dubé, it might not be feasible to mandate inoculation. When a vaccine is finally found, mass production will take a while, which means there won’t be enough doses at the start to make it mandatory, Dubé said. Past government practice across the country also makes it difficult to enforce inoculation, she said. Alberta’s public health act allows the province to make vaccines mandatory, but that’s never been pursued. Provinces like Ontario, New Brunswick, and Manitoba have implemented some mandatory vaccines, but Quebec, for example, hasn’t, Dubé said. That would make it a lot easier for Ontario than Quebec to impose a mandatory COVID-19 vaccine. Yet studies have shown that just as many people in Quebec get immunized as in Ontario, Dubé said, so making vaccines mandatory likely isn’t necessary. Plus, less than one percent of Canadians identify as anti-vaxxers. The anti-vaxxer movement is stronger in the U.S. where groups are well-funded, heavily organized, and enjoy more influence, she said. “Trust is key with governments and public health,” Dubé added. According to most estimates, the world is still at least a year away from a COVID-19 vaccine.

Demands grow for national, universal long-term care in response to pandemic

Ottawa, ON – According to a news story carried by the CBC the COVID-19 crisis has exposed critical vulnerabilities in Canada's network of long-term care facilities. Now, momentum is building in support of major reforms to improve care for the country's elderly by making long-term care a publicly funded, universal system. Painting a grim picture of the situation in seniors' homes across the country, Amanda Vyce, representing CUPE members who work as care aides, said residents are often left unbathed in soiled diapers or clothing by overworked and underpaid staff. "COVID-19 didn't create the deadly crisis we're facing in long term care. The systemic issues that facilitated this heartbreaking situation existed long before this moment. What the pandemic is doing is shining a spotlight on those problems and making them worse," she told the House of Commons health committee today. Vyce urged the federal government to work with provinces and territories to bring long-term care under the Canada Health Act, making it a publicly insured core health care service that is accessible and universal. She also called on the federal government to provide adequate, targeted funding for long-term care through the Canada Health Transfer. Canada's COVID-19 death toll passes 4,000 as provinces ease restrictions. Vyce said the federal government should work to enforce a national standard of 4.1 hours of hands-on care per resident every day — and eventually eliminate private, for-profit ownership of nursing homes. The COVID-19 crisis and its disproportionate impact on long-term care facilities has ignited a debate over long-term care in Canada. Nearly 80 per cent of COVID-19-related deaths in this country have happened in seniors' homes — a statistic Vyce called "horrifying." A Conference Board of Canada study in 2017 projected that another 199,000 long-term care beds would be needed by 2035 — a vast increase over the 255,000 beds available in 2016. Vyce said the largely profit-driven private care system is characterized by low wages, precarious employment and high levels of workplace violence and injury that make it difficult to recruit and retain workers. That, she added, has left long-term care homes dangerously short-staffed for more than a decade. When a staff member calls in sick, she said, often they're not replaced — adding to an already heavy workload. "When this occurs, staff rush from resident to resident to perform care. For residents, it means they may not receive their bath, their call bell may go unanswered, or they may sit or lay in a soiled diaper for hours," she said. "When workers don't have adequate time to perform necessary tasks, the quality of resident care suffers." Situation is 'appalling and unacceptable': NDP MP Tamara Jansen, the Conservative MP representing the B.C. riding of Cloverdale–Langley City, told CBC News in an email that the crisis in Canada's long-term care facilities was made worse by a lack of access to personal protective equipment (PPE).  "We have discovered that lack of access to personal protective gear for health care workers has contributed to the spread of infection in senior care facilities," said Jansen. "From previous pandemics we already know the importance of having a well-maintained stockpile of PPE. The Liberal government has no excuse for the situation we find ourselves in." NDP health critic Don Davies called the current situation in Canada "appalling and unacceptable." He said the country must move to bring long-term care under the Canada Health Act. "When seniors are in hospital, they are cared for in our public system. When they are transferred to long-term care, there is no reason this should change," he told CBC. "I think bringing long-term care under our public health system is key to addressing the deplorable conditions our seniors in care face. It would also result in more effective and efficient care." Erin Strumpf, a health economics expert at McGill University, said the arguments in favour of publicly funded long-term care would be similar to those in support of a national pharmacare program. "It would not necessarily be more expensive overall, but it would be more expensive for provincial and territorial governments. The extent of this shift toward the public sector would depend on current programs and mix of financing," Strumpf told CBC. With increased public coverage likely would come a greater demand for long-term care (LTC) services, Stumpf said — and without an increase in the supply, that could mean longer wait times and increased in-hospital costs. Greater government involvement also could improve the quality of care in long-term settings through regulation and workplace incentives, she said. In a media statement, Canadian Nurses Association CEO Mike Villeneuve said that Canadians should have access to long-term care based on their needs, not on their ability to pay. "We will be advocating for a dramatic overhaul of the LTC system from the ground up. Whether that means LTC falling under medicare or some parallel agreement remains to be determined and we do not want to presume those policy decisions," he said. During today's health committee meeting, Liberal MP Marcus Powlowski, a medical doctor from Thunder Bay, Ont., said he sees widespread agreement that long-term care in this country needs significant improvements. But he wondered aloud how society would pay for it. "Can we as a society afford to put that much more money into looking after elderly people? How are we going to find the money?" he asked. Vyce said questions of funding social policy programs are usually complex and difficult. "Where there is a political will, there is a way to find the money and to provide it to the services where it is most needed to support Canadians," she replied. The Canadian Institute for Health Information (CIHI) projected in 2017 that Canada's population of people aged 65 and older would jump by 68 per cent in 20 years. It predicted the number of people aged 75 and older would double over the same time period.

No evidence to date to suggest COVID-19 antibodies protect against re-infection

Geneva - There is currently no evidence to suggest that people who recover from COVID-19 and have antibodies are protected against reinfection with the illness, according to a scientific brief from WHO. As a result, although some governments have suggested that the presence of antibodies to SARS-CoV-2 may be an “immunity passport” that allows individuals to travel or return to work under the belief that they are protected from reinfection, there is no evidence to support that. The development of immunity to a pathogen through natural infection is “a multistep process” that generally occurs over the period of 1 to 2 weeks, according to the brief. The combined adaptive response may clear the virus from the body and could prevent progression to severe illness or reinfection by the same virus, if the response is strong enough. The presence of antibodies in the blood is commonly used to track this process, the brief notes. WHO officials say that as of April 24, no study has assessed whether the presence of antibodies to SARS-CoV-2 confers immunity to subsequent infection by this virus in humans and that tests that detect antibodies to SARS-CoV-2 in people need further study to establish accuracy and reliability. These tests also need to differentiate between past infections from SARS-CoV-2 and those caused by the known set of six human coronaviruses two of which cause Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome and four of which cause the common cold. According to WHO, at this point in the pandemic, there is not enough evidence regarding the effectiveness of antibody-mediated immunity to ensure the reliability of an “immunity passport” or “risk-free certificate” yet. WHO officials also noted that people who believe that they are immune to a second infection because they have received a positive test result may ignore public health advice, which could increase the risk for ongoing transmission of COVID-19. Experts from the Infectious Diseases Society of American echoed these concerns during a press briefing last week.  “The hope for antibodies has been that the detection of them in the blood represents protection for reinfection,” Mary K. Hayden, MD, FIDSA, IDSA spokesperson and professor of internal medicine and pathology at Rush University Medical Center, said during the briefing. “That's really the million-dollar question.” Hayden explained that even if antibody immunity is proven, the degree of protection is unknown and could wane over time. Because of this, it should generally be assumed that people with antibodies could be at risk for reinfection and should not change their behavior in any way regarding social distancing and other actions.

Controlled trial reports positive results for remdesivir

Maryland - National Institute of Allergy and Infectious Diseases Director Anthony S. Fauci, MD, said that data from a multinational randomized control trial showed that Gilead’s investigational antiviral remdesivir “has a clear-cut significant positive effect in diminishing time to recovery” for patients with COVID-19. “This will be the standard of care,” Fauci, a White House advisor on the pandemic, said during comments from the Oval Office. Fauci said the results, which have not yet been peer-reviewed, prove “that a drug can block this virus. We think it’s opening the door to the fact that we now have the capability of treating” COVID-19, he said. The trial, which began Feb. 21 this year, compared remdesivir with placebo in more than 1,000 patients. Remdesivir improved recovery from 15 days to 11 days, with a P value of 0.001, Fauci said. He said the mortality rate trended toward being better in the remdesivir arm, 8% vs. 11%, but the result had not reached statistical significance. “The reason why we’re making the announcement now is something that I think people don’t fully appreciate. Whenever you have clear cut evidence that you have a drug that works, you have an ethical obligation to immediately let the people in the placebo group know so that they can have access,” Fauci said. “We would have normally waited several more days. The data may change, but the conclusion won’t.” He said researchers would now start testing other investigational therapies in combination with remdesivir. Elsewhere, a study published in The Lancet showed no statistically significant benefit from remdesivir in 237 adult patients admitted to 10 hospitals in China for severe COVID-19. However, the study did show “a numerically faster time to clinical improvement” among participants who received remdesivir compared with those who received placebo among patients who experienced symptoms for 10 days or less. That finding “requires confirmation in larger studies,” the researchers wrote. Also, Gilead announced in a news release that patients with severe COVID-19 infection who received a 10-day treatment course of remdesivir experienced similar improvement in clinical status as those who were treated with a 5-day course. “The study demonstrates the potential for some patients to be treated with a 5-day regimen, which could significantly expand the number of patients who could be treated with our current supply of remdesivir,” Merdad Parsey, MD, PhD, chief medical officer of Gilead Sciences, said in the release. “This is particularly important in the setting of a pandemic, to help hospitals and health care workers treat more patients in urgent need of care.”

Blood-pressure drugs are in the crosshairs of COVID-19 research

Baltimore, Mayland - Scientists are baffled by how the coronavirus attacks the body - killing many patients while barely affecting others. But some are tantalized by a clue: A disproportionate number of patients hospitalized by COVID-19, the disease caused by the virus, have high blood pressure. Theories about why the condition makes them more vulnerable – and what patients should do about it – have sparked a fierce debate among scientists over the impact of widely prescribed blood-pressure drugs. Researchers agree that the life-saving drugs affect the same pathways that the novel coronavirus takes to enter the lungs and heart. They differ on whether those drugs open the door to the virus or protect against it. Resolving that question has taken on new urgency after an April 8 report by the U.S. Centers for Disease Control and Prevention showed that 72% of hospitalized COVID-19 patients 65 or older had hypertension. The drugs are known as ACE inhibitors and ARBs, broad categories that include Vasotec, Valsartan, Irbesartan, as well as their generic versions. In a recent interview with a medical journal, Anthony Fauci - the U.S. government’s top infectious disease expert - cited a report showing similarly high rates of hypertension among COVID-19 patients who died in Italy and suggested the medicines, rather than the underlying condition, may act as an accelerant for the virus. Efforts to understand how the virus uses the pathway to the heart and lungs, and the role of the medicines, are complicated by a lack of rigorous studies. “There are millions of Americans that take an ACE inhibitor or AR daily,” said Dr Caleb Alexander, co-director of the Johns Hopkins Center for Drug Safety and Effectiveness in Baltimore. “This is one of the most important clinical questions.” An estimated 100 million U.S. residents suffer from high blood pressure, which increases the risk of heart disease, stroke and kidney failure. About four-fifths of them need to take prescription drugs to control it, according to the CDC. ACE inhibitors and ARBs are widely prescribed to patients with congestive heart failure, diabetes or kidney disease. The drugs account for billions of dollars in prescription sales worldwide. The absence of clear answers on how the drugs impact COVID-19 patients has sparked rampant speculation in correspondence and editorials posted on medical journal websites and those where scientists share unreviewed, pre-publication study drafts. Many patients are agonizing over whether their medicines will help or hurt them.

New data on Gilead’s remdesivir show no benefit for coronavirus patients.

Geneva, Switzerland - The antiviral medicine remdesivir from Gilead Sciences failed to speed the improvement of patients with Covid-19 or prevent them from dying, according to results from a long-awaited clinical trial conducted in China. Gilead, however, said the data suggest a “potential benefit.” A summary of the study results was inadvertently posted to the website of the World Health Organization and seen by STAT on Thursday, but then removed. “A draft document was provided by the authors to WHO and inadvertently posted on the website and taken down as soon as the mistake was noticed. The manuscript is undergoing peer review and we are waiting for a final version before WHO comments,” said WHO spokesperson Tarik Jasarevic. The data (for details, see screenshot below) will be closely scrutinized but are also likely imperfect. The study was terminated prematurely, which could have affected the results. The context that would be provided by a full manuscript is missing, and the data have not been reviewed as normally occurs before publication. Many studies are being run to test remdesivir, and this one will not be the final word. Results are expected soon from a Gilead-run study in severe Covid-19 patients, although that study may be difficult to interpret because the drug is not compared to patients receiving only standard treatment. Encouraging data from patients in that study at the University of Chicago were described by researchers at a virtual town hall and obtained by STAT last week. However, unlike those data, these new results are from a randomized controlled trial, the medical gold standard. Gilead is also running a study with a control group in more moderate Covid-19 patients, and the National Institute of Allergy and Infectious Diseases is running a study that compares remdesivir to placebo. There are even more studies of the drug ongoing. According to the summary of the China study, remdesivir was “not associated with a difference in time to clinical improvement” compared to a standard of care control. After one month, it appeared 13.9% of the remdesivir patients had died compared to 12.8% of patients in the control arm. The difference was not statistically significant. “In this study of hospitalized adult patients with severe COVID-19 that was terminated prematurely, remdesivir was not associated with clinical or virological benefits,” the summary states. The study was terminated prematurely because it was difficult to enroll patients in China, where the number of Covid-19 cases was decreasing. An outside researcher said that the results mean that any benefit from remdesivir is likely to be small.

With ventilators running out, doctors say the machines are overused for Covid-19

Boston, MA - Even as hospitals and governors raise the alarm about a shortage of ventilators, some critical care physicians are questioning the widespread use of the breathing machines for Covid-19 patients, saying that large numbers of patients could instead be treated with less intensive respiratory support. If the iconoclasts are right, putting coronavirus patients on ventilators could be of little benefit to many and even harmful to some. What’s driving this reassessment is a baffling observation about Covid-19: Many patients have blood oxygen levels so low they should be dead. But they’re not gasping for air, their hearts aren’t racing, and their brains show no signs of blinking off from lack of oxygen. That is making critical care physicians suspect that blood levels of oxygen, which for decades have driven decisions about breathing support for patients with pneumonia and acute respiratory distress, might be misleading them about how to care for those with Covid-19. In particular, more and more are concerned about the use of intubation and mechanical ventilators. They argue that more patients could receive simpler, noninvasive respiratory support, such as the breathing masks used in sleep apnea, at least to start with and maybe for the duration of the illness. “I think we may indeed be able to support a subset of these patients” with less invasive breathing support, said Sohan Japa, an internal medicine physician at Boston’s Brigham and Women’s Hospital. “I think we have to be more nuanced about who we intubate.” That would help relieve a shortage of ventilators so critical that states are scrambling to procure them and some hospitals are taking the unprecedented (and largely untested) step of using a single ventilator for more than one patient. And it would mean fewer Covid-19 patients, particularly elderly ones, would be at risk of suffering the long-term cognitive and physical effects of sedation and intubation while being on a ventilator. None of this means that ventilators are not necessary in the Covid-19 crisis, or that hospitals are wrong to fear running out. But as doctors learn more about treating Covid-19, and question old dogma about blood oxygen and the need for ventilators, they might be able to substitute simpler and more widely available devices.

Chiropractors told to remove Covid-19 immune system boost claims 

Toronto, ON - There's no scientific evidence that chiropractic care can boost your immune system, but that hasn't stopped some chiropractors from touting the practice as a tool to prevent infection from the novel coronavirus that has caused the COVID-19 pandemic. The CBC recently reported that the problem is so widespread that one Ontario man has filed at least 34 complaints against chiropractic clinics in the province alone in the past few weeks. "As soon as there is public fear to exploit, these practitioners are really quick to get on message and promote this type of misinformation for their own profit," said Ryan Armstrong, who runs an independent non-profit called Bad Science Watch. He provided CBC News with copies of 34 complaints he recently filed with the College of Chiropractors of Ontario, along with the posts that triggered his complaints. In one video Armstrong had captured, three practitioners stand in front of a whiteboard with the word "Coronavirus" on top and the words "Boost your immune system" underneath. During the video, they talk about coronavirus and the need to boost your immune system through chiropractic care.  The College of Chiropractors of Ontario (CCO) said it has sent 54 cease and desist letters to practitioners since March 2nd. According to a statement from Dr. Dennis Mizel, the president of the college, the college had sent the letters "within hours of receiving information about potential inappropriate claims for the benefits of chiropractic." A different Facebook post that Armstrong shared with CBC News reads, "Covid-19? Now is the best time to see your Chiropractor! Spinal adjustments have been shown to boost your immune function."  Across the country, provincial governing bodies have issued warnings to their members not to spread misinformation about chiropractic care and COVID-19. The College of Chiropractors of B.C., the Alberta College and Association of Chiropractors, the Manitoba Chiropractors Association and L'Ordre des chiropraticiens du Quebec have all put out statements in the last week or so. Nationally, the Canadian Chiropractic Association has also warned members about making unsubstantiated claims. "We would be remiss to ignore the rise of misinformation at this difficult time. While we firmly believe in the efficacy and benefits of chiropractic care in supporting the health of Canadians, there is no scientific evidence that supports claims of a meaningful boost in immune function from chiropractic adjustments," the association wrote in a post from March 16.

Lost Sense of Smell May Be Peculiar Clue to Coronavirus Infection

London, UK - Doctor groups are recommending testing and isolation for people who lose their ability to smell and taste, even if they have no other symptoms. Anosmia, the loss of sense of smell, and ageusia, an accompanying diminished sense of taste, have emerged as peculiar telltale signs of Covid-19, the disease caused by the coronavirus, and possible markers of infection. British ear, nose and throat doctors, citing reports from colleagues around the world, called on adults who lose their senses of smell to isolate themselves for seven days, even if they have no other symptoms, to slow the disease’s spread. The published data is limited, but doctors are concerned enough to raise warnings. “We really want to raise awareness that this is a sign of infection and that anyone who develops loss of sense of smell should self-isolate,” Prof. Claire Hopkins, president of the British Rhinological Society, wrote in an email. “It could contribute to slowing transmission and save lives.” She and Nirmal Kumar, president of ENT UK, a group representing ear, nose and throat doctors in Britain, issued a joint statement urging health care workers to use personal protective equipment when treating any patients who have lost their senses of smell, and advised against performing nonessential sinus endoscopy procedures on anyone, because the virus replicates in the nose and the throat and an exam can prompt coughs or sneezes that expose the doctor to a high level of virus. Two ear, nose and throat specialists in Britain who have been infected with the coronavirus are in critical condition, Dr. Hopkins said. Earlier reports from Wuhan, China, where the coronavirus first emerged, had warned that ear, nose and throat specialists as well as eye doctors were infected and dying in large numbers, Dr. Hopkins said. The British physicians cited reports from other countries indicating that significant numbers of coronavirus patients experienced anosmia, saying that in South Korea, where testing has been widespread, 30 percent of 2,000 patients who tested positive experienced anosmia as their major presenting symptom (these were mild cases). The American Academy of Otolaryngology on Sunday posted information on its website saying that mounting anecdotal evidence indicates that lost or reduced sense of smell and loss of taste are significant symptoms associated with Covid-19, and that they have been seen in patients who ultimately tested positive with no other symptoms. The symptoms, in the absence of allergies or sinusitis, should alert doctors to screen patients for the virus and “warrant serious consideration for self-isolation and testing of these individuals,” the academy said. The organization has reminded its members that the Centers for Disease Control and Prevention.

AstraZeneca to donate 9 million face masks in fight against COVID-19

Cambridge, UK - AstraZeneca is donating nine million face masks to support healthcare workers around the world as they respond to the COVID-19 (novel coronavirus) global pandemic. AstraZeneca has partnered with the World Economic Forum’s COVID Action Platform, created with the support of the World Health Organization, to identify countries in greatest need. Italy will receive the first shipments this week with other countries to follow. In addition to these donations, AstraZeneca is accelerating the development of its diagnostic testing capabilities to scale-up screening and is also working in partnership with governments on existing screening programs to supplement testing. To help ensure the continued supply of its medicines to patients, AstraZeneca is screening employees across its manufacturing and supply network. AstraZeneca’s Research and Development (R&D) teams have also been working expeditiously to identify monoclonal antibodies to progress towards clinical trial evaluation as a treatment to prevent COVID-19. More than 50 virology, immunology, respiratory, and protein engineering experts across research, clinical, regulatory, and manufacturing are placing the highest priority on developing a treatment to minimize the global impact of the disease. Pascal Soriot, Chief Executive Officer, said: “Our first thoughts are with those suffering from this global pandemic and with the brave healthcare workers who are caring for them. As a company, we have prioritized our response by partnering with international health authorities and others to share our scientific knowledge and expertise, and we have taken this step to donate these masks as we continue to accelerate our efforts on diagnostic testing and a treatment against COVID-19.” The nine million masks will be manufactured and distributed from China, where the large-scale and accelerated effort has been aided by AstraZeneca’s leading position and strong relationships with the country’s healthcare system and manufacturing sector.  Since the start of the COVID-19 outbreak, AstraZeneca has also made financial donations and given millions of units of personal protective equipment to health organizations in China and several other countries around the world.

What happens if COVID-19 overwhelms ICUs

Toronto, ON - Within four to five weeks, doctors in Canada could be grappling with the kind of grim moral choices facing doctors in Italy, where it is being proposed that only COVID-19 patients who have the greatest chance of survival and those with the most years of potential life left get access to precious ICU beds and ventilators. Some of the nation’s leading infectious diseases and critical care doctors say that Canada needs to prepare now for a possible total saturation of intensive care resources, and begin discussing the once unthinkable: Which patients should get routed to the ICU and, of those who could hypothetically benefit, who should be left behind? “I think we should be having these conversations calmly and rationally now as opposed to waiting until it happens, and I want to emphasize if it happens,” said Dr. Anand Kumar, a critical-care doctor at Winnipeg Health Sciences Centre who is also trained in infectious diseases. Modelling suggests that ICUs may collapse under the strain of a dramatic spike in COVID-19 cases if the measures being implemented now — Ontario Premier Doug Ford’s declaration Tuesday of a state of emergency that has forced the shutdown of bars, restaurants, theatres, cinemas, schools and daycares until at least March 31, the sweeping travel restrictions announced by Prime Minister Justin Trudeau Monday, the urging of Ottawa’s medical officer of health to “stay home” — don’t buy the time needed to slow the virus’ spread. The country isn’t overrun with known infections but no one has a firm grasp on just how much community spread is occurring because we aren’t testing every person in the country with a fever or cough. As the country braces for a potential crush of the virus-infected, hospitals are restricting visitors, ramping down non-urgent procedures and surgeries to free up hospital beds, especially ventilated ones, ordering more ventilators, clearing operating rooms for virus patients and refitting mothballed ICU’s. In Toronto, lung and living kidney donor transplants have been put on hold for 14 days to free up ICU beds. Even then, “the system is likely to be overwhelmed and that’s why I think we need to get more aggressive with this now while we have time,” Kumar said, adding that the kind of aggressive social distancing measures announced by Ontario and Quebec should be implemented nationwide. In China and Italy, five per cent or more of those known infected with COVID-19 require intensive care. Among all infected people, the death rate is hovering at around one to three per cent, but among the critically ill, it climbs as high as 62 per cent. Most deaths are due to hypoxia, an insufficient supply of oxygen to the body’s tissues, or multi-organ collapse. There are currently about 3,200 ICU beds in the country. “So maybe you double that by throwing everything you’ve got at it,” Kumar said. “You increase your bed capacity by an additional 3,000 beds or maybe 4,000 beds.” In the U.S., 20 per cent of the population was infected with H1N1 in the first year of the outbreak. One-third of the world’s population became infected with the 1918 pandemic virus. If one-quarter of the Canadian population is infected with COVID-19 in the first year, “that’s roughly 10 million people,” he said. If five per cent require ICU support that could mean 500,000 people requiring intensive care.

We have a youth vaping crisis

Ottawa, ON - More than one third of teenagers 15 to 19 have tried vaping at some point in their lives, according to a new report from Statistics Canada, the first of its kind to provide detailed information about vaping. The Canadian Tobacco and Nicotine Survey, based on data collected from 8,600 people in November and December 2019, found that 36 per cent of teens in that age bracket had tried vaping, and 15 per cent reported doing so in the past 30 days. "The new data reinforces the trend that we've been seeing over the last short while, which is that we have a youth vaping crisis," said Sarah Butson, public policy analyst for The Lung Association. "It demonstrates to us that vaping is in the hands of exactly the folks we are trying to protect and really emphasizes that we need to do more." She said The Lung Association has been calling for stricter regulation of vaping products, including a wholesale ban on flavours, "which are an incredibly powerful marketing tool for young people." Likewise, 15 per cent of young adults ages 20 to 24 had vaped in the 30 days prior to the survey, while nearly half (48 per cent) had done so in the their lifetimes. In comparison, just three per cent of adults ages 25 and older reported that they had used a vaping product in the previous month, while 12 per cent had tried it at least once in the past. Among the people surveyed who had vaped in the past 30 days, about 80 per cent had vaped nicotine. Reasons for vaping vary across age groups. Those who responded to the survey were asked to identify their main reason for vaping in the 30 days prior to the survey. Among users ages 15 to 19, 29 per cent chose "because they wanted to try" and another 29 per cent picked "because they enjoyed it." Only nine per cent of teens surveyed cited a desire to quit or cut down on smoking cigarettes as their main motivation for vaping. But among the 20- to 24-year-old cohort, 28 per cent said smoking cessation was their main reason, along with more than half of those 25 and older. Sarah Butson, public policy analyst for The Lung Association, said the organization is calling for stricter regulation of vaping products, including a wholesale ban on flavours, which she says are very powerful for enticing young people to take up the habit. When vaping products first came to market, they were billed as harm-reduction and smoking cessation tools for tobacco users. But Butson said it's unclear they're effective that way. "What we've seen to date is that the evidence is really inconclusive to suggest that e-cigarettes can be a cessation aid," she said. Instead, the association urges Canadians to talk to their health care providers about evidenced-based tools that can help them quit smoking. 'We need to do more' Butson said there's been good strides made at the provincial level, with some moving to restrict flavours and increase the age to purchase vaping products. "We would like to see that happen at the federal level, to really set the benchmark and make sure that we don't have disparity across provinces so that we're really protecting all Canadians, in particular all young Canadians." Butson said youth have a number of misconceptions around vaping. "One of the most common myths is that it's harmless," she said. In fact, vaping-related illness is on the rise in both Canada and the U.S.

Feds propose changes to medical assistance in dying legislation

Ottawa, ON - Medical assistance in dying (MAID) is a complex and deeply personal issue. Last week the Honourable David Lametti, Minister of Justice and Attorney General of Canada, the Honourable Patty Hajdu, Minister of Health, and the Honourable Carla Qualtrough, Minister of Employment, Workforce Development and Disability Inclusion, announced the introduction of a bill, which proposes changes to Canada’s Criminal Code provisions on MAID. The Bill would remove the requirement for a person’s natural death to be reasonably foreseeable in order to be eligible for MAID. Introduce a two-track approach to procedural safeguards based on whether or not a person’s natural death is reasonably foreseeable. Existing safeguards will be maintained and certain ones will be eased for eligible persons whose death is reasonably foreseeable. New and modified safeguards will be introduced for eligible persons whose death is not reasonably foreseeable. The bill will also exclude eligibility for individuals suffering solely from mental illness; allow waiver of final consent for eligible persons whose natural death is reasonably foreseeable and who may lose capacity to consent before MAID can be provided. The government plans to expand data collection through the federal monitoring regime to provide a more complete picture of MAID in Canada. The introduction of this Bill would respond to the Superior Court of Québec’s September 2019 Truchon decision by allowing individuals who are not nearing the end of their lives to be eligible to receive MAID. The amended procedural safeguards would require practitioners to take appropriate steps to ensure that, in non-end-of-life cases, the request for MAID is fully informed and considered, and that individuals making the request have given serious consideration to reasonable and available treatment options. The Bill also reflects emerging societal consensus and was informed by views and concerns raised by Canadians, experts, practitioners, stakeholders, Indigenous groups, as well as provinces and territories during the January and February 2020 consultations. It is also informed by the past four years of experience with MAID in Canada. The Government of Canada would continue to work closely with provinces and territories, health system partners, and health practice regulatory bodies to support the implementation of the proposed changes to the legislation, if passed by Parliament. This includes the development of monitoring, reporting, best practices, and guidance for the MAID regime. In addition, the federal government will work with provincial and territorial partners to enhance disability support. Other important questions relating to MAID in Canada—such as advance requests for persons newly diagnosed with a condition that could affect their decision-making capacity in the future, eligibility for persons suffering solely from mental illness and eligibility for mature minors—could be considered during a broader parliamentary review of MAID legislation expected to begin by June 2020.

Hospitals across the US prepare for coronavirus global pandemic

Atlanta, GA - “This is the time to open up your pandemic plans and see that things are in order,” Dr. Anne Schuchat, a top official of the Centers for Disease Control and Prevention, urged hospitals last week as an outbreak of a deadly new coronavirus ravaged much of China. “For instance,” she continued, health-care providers need to plan for a “surge at a hospital, the ability to provide personal protective equipment for your workforce, the administrative controls and so forth that you might put place in a health care setting.” Schuchat’s warning came as U.S. and world health officials increasingly sound the alarm of a possible pandemic outbreak of the deadly new coronavirus that has killed more than 2,100 people in China in the last seven weeks. The COVID-19 epidemic in China has not yet met world health officials’ designation of a global pandemic that spreads far and wide throughout the world. While it has spread to more than two dozen countries, international health officials say there’s very little transmission on local levels outside of China right now. But they’ve warned that could quickly change. The virus is proving to be far more contagious than the flu, having spread from 300 people in mid-January to more than 75,700 as of Thursday morning. While a majority of those cases are in China — with just 15 confirmed in the U.S. — the CDC has been working with the health-care sector to prepare for the virus to “take a foothold in the U.S,” Dr. Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases, told reporters Feb. 12. “At some point, we are likely to see community spread in the U.S. or in other countries,” she warned. U.S. hospitals from San Diego to New York are taking heed. The threat of the new virus comes at an already busy time for most U.S. hospitals. Another serious respiratory illness, the seasonal flu, is at its peak in the United States, with more than 26 million cases and many hospitals stretched thin. A larger spread of the new virus across the U.S. could overwhelm emergency rooms and quickly cause supply shortages of some crucial medical supplies, according to half a dozen interviews with doctors, U.S. hospitals and health systems.

Impact of comorbidities and commonly used drugs on mortality in COPD

Uppsala, Sweden - Life expectancy is significantly shorter for patients with chronic obstructive pulmonary disease (COPD) than the general population. Concurrent diseases are known to infer an increased mortality risk in those with COPD, but the effects of pharmacological treatments on survival are less established. Researchers here aimed to examine any associations between commonly used drugs, comorbidities and mortality in Swedish real-world primary care COPD patients. Patients with physician-diagnosed COPD from a large primary care population were observed retrospectively, utilizing primary care records and mandatory Swedish national registers. The time to all-cause death was assessed in a stepwise multiple Cox proportional hazards regression model including demography, socioeconomic factors, exacerbations, comorbidities and medication. During the observation period (1999– 2009) 5776 (32.5%) of 17,745 included COPD patients died. Heart failure (hazard ratio [HR]: 1.88, 95% confidence interval [CI]: 1.74– 2.04), stroke (HR: 1.52, 95% CI: 1.40– 1.64) and myocardial infarction (HR: 1.40, 95% CI: 1.24– 1.58) were associated with an increased risk of death. Use of inhaled corticosteroids (ICS; HR: 0.79, 95% CI: 0.66– 0.94), beta-blockers (HR: 0.86, 95% CI: 0.76– 0.97) and acetylsalicylic acid (ASA; HR: 0.87, 95% CI: 0.77– 0.98) was dose-dependently associated with a decreased risk of death, whereas use of long-acting muscarinic antagonists (LAMA; HR: 1.33, 95% CI: 1.14– 1.55) and N-acetylcysteine (NAC; HR: 1.26, 95% CI: 1.08– 1.48) were dose-dependently associated with an increased risk of death in COPD patients. This large, retrospective, observational study of Swedish real-world primary care COPD patients indicates that coexisting heart failure, stroke and myocardial infarction were the strongest predictors of death, underscoring the importance of timely recognition and treatment of comorbidities. A decreased risk of death associated with the use of ICS, beta-blockers and ASA, and an increased risk associated with the use of LAMA and NAC, was also found. Lead author of the study is J. Ellingsen of the Department of Medical Sciences, Respiratory, Allergy and Sleep Research, Uppsala University, Uppsala, Sweden

Model suggests coronavirus outbreak began earlier than reported

Toronto, ON - The coronavirus epidemic started one month earlier than is commonly reported and has yet to be brought under control, a new disease-transmission model created by University of Toronto researchers suggests. Using open access data that are updated daily, the model replicates epidemiological scenarios and allows researchers to test narratives about the outbreak that originated in Wuhan, China – including the notion that it started in December. The work is detailed in the Annals of Internal Medicine. “You can’t get up to that level of cases if the epidemic started in December even if you pushed the reproduction really high,” says David Fisman, a professor in the Dalla Lana School of Public Health and one of the model’s creators. “If you have a reproduction number of three, the epidemic could not have stated in mid-December because, according to the graph, it is undershooting the cases that were found in December.” In epidemiology, reproduction refers to the number of secondary cases a single case can infect in a susceptible population. “It had to be earlier, which raises some interesting questions about how this emerged,” Fisman says. “The plausible start date seems to be mid-November.”  The tool also shed insights into the international effort to contain the spread of the virus. The Chinese government implemented containment measures by mid-January, but, according to the model’s graph, the disease’s reproduction number has not yet been reduced below one – the level needed for control. “Even with the reproduction being less than one ... when looking at Jan. 14, that level control is not happening because the observed cases are exceeding that level,” Fisman says. Reproduction numbers have not been less than one since the World Health Organization formally declared the epidemic a public health emergency of international concern on Jan. 30, according to the model. Fisman says it takes about a week to infect someone and for the person to exhibit the virus’ symptoms. “What you’re seeing today [in the graph] is what happened last week.” The model also allows users to create plausible epidemic curves or scenarios to observe the outbreak’s trajectory. Fisman says it is a simplified version of reality that can rule out ongoing narratives. “You can play with this to see how the response is doing,” he says. “It’s a qualitative tool, but there’s also a lot we can’t say with certainty. If the cases take a sharp right turn and stop going up, there are two possibilities: control has been achieved or they are running out of resources.  We can’t distinguish those with the graph alone.” Fisman and Tuite will be working on the virus’s lethality for an upcoming paper.

Tech to support aging in place

Ottawa, ON - More than 90 per cent of Canadians aged 65 and older are currently living in private residences. And most, if not all, of them want to remain there as long as possible. To support this desire to “age in place,” there are many new health technologies being developed that aim to help older adults remain healthier, more productive, and living in their own communities. In a recent issue of Health Technology Update, CADTH looked at a few emerging technologies that could potentially help support aging in place. CADTH is an independent agency that finds, assesses, and summarizes the research on drugs, medical devices, tests, and procedures to find out what the evidence says. Its Health Technology Update newsletter describes new and emerging health technologies that are likely to have a significant impact on health care in Canada. The technologies described in this recent issue aren’t yet available in Canada, with the exception of the virtual-reality bike, described next. A virtual reality-inspired exercise bike that rides you through places that hold fond memories could be the ticket to improved physical, memory-related, and cognitive abilities. But how can this be made possible? BikeAround combines a stationary bike with Google Street View to create a virtual bike riding experience. It has been developed for use by older adults experiencing physical disabilities, memory problems, or cognitive disabilities such as dementia or Alzheimer disease. The technology allows users to tour their childhood communities, favourite vacation spots, or any other place they wish to revisit simply by typing the desired address into Google on the BikeAround laptop. This activity is intended to improve memory skills as well as provide social engagement for participants, who are encouraged to discuss their ride with an attendant or volunteer assisting with the session. Even users with mobility limitations can experience the cognitive and reminiscent therapy by having a trained assistant navigate the streets for them. BikeAround bikes are typically set up at locations within communities and have been commercially available and distributed in Canada since 2018. Older adults experiencing physical and mental decline may eventually need someone to keep an eye on them, either through an in-home care arrangement or by moving to an assisted living or nursing home facility. But smart home technology could someday offer health monitoring that could allow older adults to live independently at home for longer. The concept of wireless smart home monitoring technology isn’t new, but a system that claims to take the concept further is in the works. Called Emerald, it uses radiofrequency signals to track, and differentiate between, multiple individuals; measure breathing, heart rate, and sleep; and learn about patterns of human activity in a house. This could allow the system to detect falls and measure cognitive decline, mental health, and chronic conditions remotely and unobtrusively, allowing older adults to live independently and alleviating the need for trips to the hospital. As is typically the case with new and emerging technologies, there’s currently only limited evidence on their effectiveness or how they compare with existing treatments. But early awareness of interventions that might come into broad use can help us plan for their possible introduction into the Canadian health care system.

Study looks at using virtual reality training as rehab tool for patients with COPD

Opole, Poland – This study compared the effects of inpatient-based rehabilitation program of patients with chronic obstructive pulmonary disease (COPD) using non-immersive virtual reality (VR) training with a traditional pulmonary rehabilitation program. The aim of this study was to determine whether rehabilitation featuring both VR as well as exercise training provides benefits over exercise training (ET) alone or whether rehabilitation featuring VR training instead of exercise training provides equivalent benefits. The study recruited 106 patients with COPD to a 2-week high-intensity, five times a week intervention. Randomized into three groups, 34 patients participated in a traditional pulmonary rehabilitation program including endurance exercise training (ET), 38 patients participated in traditional pulmonary rehabilitation, including both endurance exercise training and virtual reality training (ET+VR) and 34 patients participated in pulmonary rehabilitation program including virtual reality training but no endurance exercise training (VR). The traditional pulmonary rehabilitation program consisted of fitness exercises, resistance respiratory muscle and relaxation training. Xbox 360® and Kinect® Adventures software was used for the VR training of lower and upper body strength, endurance, trunk control and dynamic balance. Comparison of the changes in the Senior Fitness Test was the primary outcome. Analysis was performed using linear mixed-effects models. The comparison between ET and ET+VR groups showed that ET+VR group was superior to ET group in Arm Curl (p< 0.003), Chair stand (p< 0.008), Back scratch (p< 0.002), Chair sit and reach (p< 0.001), Up and go (p< 0.000), 6-min walk test (p< 0.011). Whereas, the comparison between ET and VR groups showed that VR group was superior to ET group in Arm Curl (p< 0.000), Chair stand (p< 0.001), 6-min walk test (p< 0.031). Results suggest that pulmonary rehabilitation program supplemented with VR training is beneficial intervention to improve physical fitness in patients with COPD. Lead author of the study was Sebastian Rutkowski of the Institute of Physiotherapy, Department of Physical Education and Physiotherapy, Opole University of Technology.

"Skyping' your GP could be in your future

St. John, NB - Take two aspirin and Skype me in the morning." That could be a phrase in your future if the New Brunswick Medical Society succeeds with its call for more virtual care in the province. Virtual care could include anything from doctors emailing test results to patients, to holding a consultation over Skype. Chris Goodyear, the society's president, said the idea of virtual care isn't to replace the standard doctor visit but to augment it. "It is a tool that a physician can use to see a patient when a physical exam is not necessary," said Goodyear. He said a lot of care is now done outside hospitals or doctors' offices, so this is a logical step. "Years ago, the only time you would get your blood pressure checked would be when you went to your family doctor's office," said Goodyear.  "Nowadays blood pressure machines are in pharmacies, they're in gyms, you can do it at home, you can constantly monitor your blood pressure … that part of the physical exam that a doctor would perform is no longer necessary in the office." Goodyear said virtual care would not solve the doctor shortage problem, but it would help. As of July 2018, more than 44,000 New Brunswickers without a family doctor. And an aging population, which would include many doctors reaching retirement age, will exacerbate the shortage that already exists. Dr. Chris Goodyear is a surgeon and president of the New Brunswick Medical Society, and he's hoping to roll out virtual care in the province. "Virtual care is being tested in other parts of North America," said Goodyear. "The feedback we're getting from physicians is that by incorporating that model as part of what they provide patients, it allows them to be more efficient, which does free up some time to get patients seen quicker and to expand their practice." Goodyear said some privacy concerns would need to be addressed before any regime was implemented. "There are platforms where the technology does exist to have this done on a secure platform," said Goodyear.  "People do their banking online nowadays. So they are comfortable with the notion of, you know, their personal information being ... out there in the Internet."

Smoking increases risk for invasive fungal disease

Paris, France - The risk for invasive fungal disease is higher among smokers, according to data from a recent study, leading researchers to suggest that strategies to end smoking be implemented, particularly among those already at increased risk for invasive fungal disease. “Invasive fungal disease (IFD) is a major cause of morbidity and mortality in immunocompromised hosts,” Annabelle Pourbaix, of the Necker-Pasteur Center for Infectious Diseases and Tropical Medicine, Paris, and colleagues wrote. “The general population may be at risk for IFD as well, as a result of specific environmental exposures, such as climate and agricultural profession, and lifestyle habits, such as smoking. Several studies have assessed the association between smoking and infection. Smoking increases the risk for bacterial pneumonia and meningitis and second-hand smoke exposure is associated with increased risk for childhood invasive meningococcal disease.” Pourbaix and colleagues performed a systematic review and meta-analysis that included 25 studies collected from MEDLINE and Web of Science published through September 2018 to investigate the correlation between smoking and risk for IFD. Results of the analysis showed that there was a greater risk for IFD among smokers (RR = 1.41; 95% CI, 1.09-1.81). The risk for IFD was higher among participants in the retrospective studies compared with those in the prospective studies (RR = 1.93 [95% CI, 1.28-2.92] vs. RR = 1.02 [95% CI, 0.78-1.34]), as well as studies that included multivariate adjustments compared to studies with univariate analysis (RR = 2.15 [95% CI, 1.27-3.64] vs. RR = 1.15 [95% CI, 0.88-1.51]) and in studies published after 2002 (RR = 2.08 [95% CI, 1.37-3.15] vs. RR = 0.95 [95% CI, 0.75-1.22]).  “This review and meta-analysis showed an increased risk for IFD among smokers, with a stable association across a variety of clinical subgroups,” the authors concluded. “This provides new evidence supporting the implementation of smoking cessation strategies, including tobacco, marijuana, opium and crack cocaine, especially in patients with HIV and patients with hematological malignancies who are already at higher risk for IFD.”

Canadian officials closely monitoring mysterious virus based in China

Ottawa, ON - Seventeen years after SARS killed 44 Canadians and sickened hundreds of others, Canadian officials are closely monitoring a new potential threat — a mysterious virus based in China that has caused atypical pneumonia in at least 59 people. So far, Chinese officials have ruled out SARS (Severe Acute Respiratory Syndrome), which also began in China in 2002. They have also ruled out bird flu, influenza and Middle East Respiratory Syndrome, among other potential causes. Officials say there is no evidence yet that it has spread from human to human. But the world is watching closely. Not just because there are so many unanswered questions about the cluster of undiagnosed viral pneumonia cases in Wuhan, China, but because global infectious disease officials have long warned that another pandemic is coming. Canada’s Chief Public Health Officer Dr. Theresa Tam has been in touch with provincial and territorial public health officials, the World Health Organization and other international partners to discuss the mysterious virus, said Eric Morrissette, spokesman for the Public Health Agency of Canada. The Ontario Ministry of Health is also monitoring the situation, said spokesman David Jensen. “As the situation develops, the ministry will continue to assess and determine whether any further action is needed,” said Jensen. Could this become a global public health threat? For now, public health officials are watching and trying to get more information. But the virus in Wuhan should serve as a wakeup call about the implications of overcrowding in Ontario hospitals for outbreaks or a pandemic, said Dr. Alan Drummond, a Perth emergency physician who is co-chair of public affairs for the Canadian Association of Emergency Physicians. A Public Health Agency of Canada spokesman notes that numerous system improvements have been put in place since the SARS outbreak, which killed 774 people worldwide, 44 of them in Toronto. Those changes include new and improved systems in Canadian provinces and territories to “identify, prevent and control the spread of serious infectious diseases into and within Canada.” Post-SARS protections also include a global public health intelligence monitoring system, which scans the world’s open source media, in addition to international collaboration and information sharing across Canada, said Morrissette. “The Canadian public health laboratory system is well-equipped to detect serious infectious diseases,” he added.
