Covid ICYMI

The Centers for Disease Control and Prevention (CDC) today abruptly deleted information from its website that it had updated Friday on how COVID-19 is spread.

The CDC had updated information on coronavirus spread and had acknowledged the prominence of aerosol transmission.

CDC’s new information still says that Sars-CoV-2 is commonly spread between people who are within about 6 feet of each other, which has been the agency’s stance for months now.

However, the deleted update had added it is spread “through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes. These particles can be inhaled into the nose, mouth, airways, and lungs and cause infection. This is thought to be the main way the virus spreads.”

Responding to Medscape Medical News questions about the update, Jasmine Reed, spokesperson for the CDC, told Medscape Medical News, “A draft version of proposed changes to these recommendations was posted in error to the agency’s official website. CDC is currently updating its recommendations regarding airborne transmission of SARS-CoV-2 (the virus that causes COVID-19). Once this process has been completed, the updated language will be posted.”

Previous information

Previously, the CDC said the virus is spread mainly among people who are within about 6 feet of each another through respiratory droplets propelled when an infected person coughs, sneezes, or talks.

Previous guidance also said, “These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.”

The now deleted update said, “There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes).”

On July 6, Clinical Infectious Diseases published the paper “It Is Time to Address Airborne Transmission of Coronavirus Disease 2019,” which was supported by 239 scientists.

The authors write, “There is significant potential for inhalation exposure to viruses in microscopic respiratory droplets (microdroplets) at short to medium distances (up to several meters, or room scale).

The World Health Organization (WHO) acknowledged after this research was published that airborne transmission of the virus may play a role in infection, especially in poorly ventilated rooms and buildings, but have yet to declare aerosols as a definitive contributor.

WHO has long stated that coronavirus is spread mainly by droplets that, once expelled by coughs and sneezes of infected people, fall quickly to the floor.

The CDC update was made Friday without announcement.

“This has been one of the problems all along,” said Leana Wen, MD, an emergency physician and public health professor at George Washington University, Washington, DC. “The guidance from CDC changes on their website, but there’s no press conference, there’s no explanation of why they’re changing this now.”

Again Monday, there was no announcement that information had changed.

Update added air purifiers for prevention

The CDC continues to recommend staying 6 feet from others, washing hands, wearing a mask and routinely disinfecting frequently touched surfaces.

The update had added, “Use air purifiers to help reduce airborne germs in indoor spaces.”

A new study using cardiac magnetic resonance (CMR) imaging to examine the effects of novel coronavirus infection on the heart showed signs suggestive of myocarditis in 4 out of 26 competitive athletes who recovered from asymptomatic or mild cases of COVID-19.

While these and other similar findings are concerning, commentators are saying the results are preliminary and do not indicate widespread CMR screening is appropriate.

Two of the 4 patients showing signs of myocarditis in this series had no symptoms of COVID-19 but tested positive on routine testing. An additional 12 student athletes (46%) showed late gadolinium enhancement (LGE), of whom 8 (30.8%) had LGE without T2 elevation suggestive of prior myocardial injury.

An additional 12 student athletes (46%) showed late gadolinium enhancement (LGE), of whom 8 (31%) had LGE without T2 elevation suggestive of prior myocardial injury.

This finding, said Saurabh Rajpal, MBBS, MD, the study’s lead author, “could suggest prior myocardial injury or it could suggest athletic myocardial adaptation.”

In a research letter published in JAMA Cardiology, Rajpal and colleagues at Ohio State University in Columbus, described the findings of comprehensive CMR examinations in competitive athletes referred to the sport medicine clinic after testing positive for COVID-19 on reverse transcriptase-polymerase chain reaction between June and August 2020.

The university had made the decision in the spring to use CMR imaging as a screening tool for return to play, said Dr. Rajpal. While CMR is being used for research purposes, the American College of Cardiology’s recent “consensus expert opinion” statement on resumption of sport and exercise after COVID-19 infection does not require CMR imaging for resumption of competitive activity (JAMA Cardiol. 2020 May 13. doi:10.1001/jamacardio.2020.2136).

None of the athletes required hospitalization for their illness, and only 27% reported mild symptoms during the short-term infection, including sore throat, shortness of breath, myalgia, and fever.

On the day of CMR imaging, ECG and transthoracic echocardiography were performed, and serum troponin I was measured. There were no diagnostic ST/T wave changes, ventricular function and volumes were normal, and no athletes showed elevated serum troponin levels.

The updated Lake Louise Criteria were used to assess CMR findings consistent with myocarditis.

“I don’t think this is a COVID-specific issue. We have seen myocarditis after other viral infections; it’s just that COVID-19 is the most studied thus far, and with strenuous activity, inflammation in the heart can be risky,” Dr. Rajpal said in an interview. He added that more long-term and larger studies with control populations are needed.

His group is continuing to follow these athletes and has suggested that CMR “may provide an excellent risk-stratification assessment for myocarditis in athletes who have recovered from COVID-19 to guide safe competitive sports participation.”
 

Significance still unknown

Matthew Martinez, MD, the director of sports cardiology at Atlantic Health – Morristown (N.J.) Medical Center and the Gagnon Cardiovascular Institute, urged caution in making too much of the findings of this small study.

“We know that viruses cause myocardial damage and myocarditis. What we don’t know is how important these findings are. And in terms of risk, would we find the same phenomenon if we did this, say, in flu patients or in other age groups?” Dr. Martinez said in an interview.

“I haven’t seen all the images, but what I’d want to know is are these very subtle findings? Are these overt findings? Is this part of an active individual with symptoms? I need to know a little more data before I can tell if this influences the increased risk of sudden cardiac death that we often associate with myocarditis. I’m not sure how this should influence making decisions with regards to return to play.”

Dr. Martinez, who is the ACC’s chair of Sports and Exercise but was not an author of their recent guidance on return to sport, said that he is not routinely using CMR to assess athletes post-infection, as per the ACC’s recommendations.

“My approach is to evaluate anybody with a history of COVID infection and, first, determine whether it was an important infection with significant symptoms or not. And then, if they’re participating at a high level or are professional athletes, I would suggest an ECG, echo, and troponin. That’s our recommendation for the last several months and is still an appropriate way to evaluate that group.”

“In the presence of an abnormality or ongoing symptoms, I would ask for an MRI at that point,” said Dr. Martinez.

“We just don’t have much data on athletes with no symptoms to use to interpret these CMR findings and the study didn’t offer any controls. We don’t even know if these findings are new findings or old findings that have just been identified now,” he added.

New, updated recommendations from the ACC are coming soon, said Dr. Martinez. “I do not expect them to include CMR as first line.”
 

Cardiologists concerned about misinformation

This is at least the fourth study showing myocardial damage post-COVID-19 infection and there is concern in the medical community that the media has overstated the risks of heart damage, especially in athletes, and at the same time overstated the benefits of CMR.

In particular, Puntmann et al reported in July a 100-patient study that showed evidence of myocardial inflammation by CMR in 78% of patients recently recovered from a bout of COVID-19 (JAMA Cardiol. 2020 Jul 27; doi:10.1001/jamacardio.2020.3557).

“That paper is completely problematic,” John Mandrola, MD, of Baptists Medical Associates, Louisville, Ky., said in an interview. “It has the same overarching weaknesses [of other studies] that it’s observational and retrospective, but there were also numerical issues. So to me that paper is an interesting observation, but utterly unconvincing and preliminary,” said Dr. Mandrola.

Those limitations didn’t stop the study from garnering media attention, however. The Altmetric score (an attention score that tracks all mentions of an article in the media and on social media) for the Puntmann et al paper is approaching 13,000, including coverage from 276 news outlets and more than 19,000 tweets, putting it in the 99th percentile of all research outputs tracked by Altmetric to date.

To counter this, an “open letter” posted online just days before the Rajpal study published urging professional societies to “offer clear guidance discouraging CMR screening for COVID-19 related heart abnormalities in asymptomatic members of the general public.” The letter was signed by 51 clinicians, researchers, and imaging specialists from around the world.

Dr. Mandrola, one of the signatories, said: “This topic really scares people, and when it gets in the media like this, I think the leaders of these societies need to come out and say something really clear on major news networks letting people know that it’s just way too premature to start doing CMRs on every athlete that’s gotten this virus.”

“I understand that the current guidelines may be clear that CMR is not a first-line test for this indication, but when the media coverage is so extensive and so overblown, I wonder how much impact the guidelines will have in countering this fear that’s in the community,” he added.

Asked to comment on the letter, Dr. Rajpal said he agrees with the signatories that asymptomatic people from general population do not need routine cardiac MRI. “However, competitive athletes are a different story. Testing depends on risk assessment in specific population and competitive athletes as per our protocol will get enhanced cardiac workup including CMR for responsible and safe start of competitive sports. ... In the present scenario, while we get more data including control data, we will continue with our current protocol.”

An international survey provides new insights into how COVID-19 has affected, and may continue to affect, the field of oncology.

The survey showed that “COVID-19 has had a major impact on the organization of patient care, on the well-being of caregivers, on continued medical education, and on clinical trial activities in oncology,” stated Guy Jerusalem, MD, PhD, of Centre Hospitalier Universitaire de Liège (Belgium).

Dr. Jerusalem presented these findings at the European Society for Medical Oncology Virtual Congress 2020.

The survey was distributed by 20 oncologists from 10 of the countries most affected by COVID-19. Responses were obtained from 109 oncologists representing centers in 18 countries. The responses were recorded between June 17 and July 14, 2020.

The survey consisted of 95 items intended to evaluate the impact of COVID-19 on the organization of oncologic care. Questions encompassed the capacity and service offered at each center, the magnitude of COVID-19–based care interruptions and the reasons for them, the ensuing challenges faced, interventions implemented, and the estimated harms to patients during the pandemic.

The 109 oncologists surveyed had a median of 20 years of oncology experience. A majority of respondents were men (61.5%), and the median age was 48.5 years.

The respondents had worked predominantly (62.4%) at academic hospitals, with 29.6% at community hospitals. Most respondents worked at general hospitals with an oncology unit (66.1%) rather than a specialized separate cancer center (32.1%).

The most common specialty was breast cancer (60.6%), followed by gastrointestinal cancer (10.1%), urogenital cancer (9.2%), and lung cancer (8.3%).
 

Impact on treatment

The treatment modalities affected by the pandemic – through cancellations or delays in more than 10% of patients – included surgery (in 34% of centers), chemotherapy (22%), radiotherapy (13.7%), checkpoint inhibitor therapy (9.1%), monoclonal antibodies (9%), and oral targeted therapy (3.7%).

Among oncologists treating breast cancer, cancellations/delays in more than 10% of patients were reported for everolimus (18%), CDK4/6 inhibitors (8.9%), and endocrine therapy (2.2%).

Overall, 34.8% of respondents reported increased use of granulocyte colony–stimulating factor, and 6.4% reported increased use of erythropoietin.

On the other hand, 11.1% of respondents reported a decrease in the use of double immunotherapy, and 21.9% reported decreased use of corticosteroids.

Not only can the immunosuppressive effects of steroid use increase infection risks, Dr. Jerusalem noted, fever suppression can lead to a delayed diagnosis of COVID-19.

“To circumvent potential higher infection risks or greater disease severity, we use lower doses of steroids, but this is not based on studies,” he said.

“Previous exposure to steroids or being on steroids at the time of COVID-19 infection is a detrimental factor for complications and mortality,” commented ESMO President Solange Peters, MD, PhD, of Centre Hospitalier Universitaire Vaudois in Lausanne, Switzerland.

Dr. Peters noted that the observation was based on lung cancer registry findings. Furthermore, because data from smaller outbreaks of other coronavirus infections suggested worse prognosis and increased mortality, steroid use was already feared in the very early days of the COVID-19 pandemic.

Lastly, earlier cessation of palliative treatment was observed in 32.1% of centers, and 64.2% of respondents agreed that undertreatment because of COVID-19 is a major concern.

Dr. Jerusalem noted that the survey data do not explain the early cessation of palliative treatment. “I suspect that many patients died at home rather than alone in institutions because it was the only way they could die with their families around them.”
 

Telehealth, meetings, and trials

The survey also revealed rationales for the use of teleconsultation, including follow-up (94.5%), oral therapy (92.7%), immunotherapy (57.8%), and chemotherapy (55%).

Most respondents reported more frequent use of virtual meetings for continuing medical education (94%), oncologic team meetings (92%), and tumor boards (82%).

While about 82% of respondents said they were likely to continue the use of telemedicine, 45% said virtual conferences are not an acceptable alternative to live international conferences such as ESMO, Dr. Jerusalem said.

Finally, nearly three-quarters of respondents (72.5%) said all clinical trial activities are or will soon be activated, or never stopped, at their centers. On the other hand, 27.5% of respondents reported that their centers had major protocol violations or deviations, and 37% of respondents said they expect significant reductions in clinical trial activities this year.

Dr. Jerusalem concluded that COVID-19 is having a major, long-term impact on the organization of patient care, caregivers, continued medical education, and clinical trial activities in oncology.

He cautioned that “the risk of a delayed diagnosis of new cancers and economic consequences of COVID-19 on access to health care and cancer treatments have to be carefully evaluated.”

This research was funded by Fondation Léon Fredericq. Dr. Jerusalem disclosed relationships with Novartis, Roche, Lilly, Pfizer, Amgen, Bristol-Myers Squibb, AstraZeneca, Daiichi Sankyo, AbbVie, MedImmune, and Merck.

An international survey provides new insights into how COVID-19 has affected, and may continue to affect, the field of oncology.

The survey showed that “COVID-19 has had a major impact on the organization of patient care, on the well-being of caregivers, on continued medical education, and on clinical trial activities in oncology,” stated Guy Jerusalem, MD, PhD, of Centre Hospitalier Universitaire de Liège (Belgium).

Dr. Jerusalem presented these findings at the European Society for Medical Oncology Virtual Congress 2020.

The survey was distributed by 20 oncologists from 10 of the countries most affected by COVID-19. Responses were obtained from 109 oncologists representing centers in 18 countries. The responses were recorded between June 17 and July 14, 2020.

The survey consisted of 95 items intended to evaluate the impact of COVID-19 on the organization of oncologic care. Questions encompassed the capacity and service offered at each center, the magnitude of COVID-19–based care interruptions and the reasons for them, the ensuing challenges faced, interventions implemented, and the estimated harms to patients during the pandemic.

Having low serum vitamin D levels was an independent risk factor for having symptomatic COVID-19 with respiratory distress requiring admission to intensive care – as opposed to having mild COVID-19 – and for not surviving, in a new study from Italy.

“Our data give strong observational support to previous suggestions that reduced vitamin D levels may favor the appearance of severe respiratory dysfunction and increase the mortality risk in patients affected with COVID-19,” the researchers report.

Luigi Gennari, MD, PhD, Department of Medicine, Surgery, and Neurosciences, University of Siena, Italy, presented these findings during the virtual American Society of Bone and Mineral Research (ASBMR) 2020 annual meeting.

Gennari told Medscape Medical News that this analysis suggests determining vitamin D levels (25 hydroxyvitamin D) in people testing positive for SARS-Cov-2 infection might help predict their risk of severe disease.

However, further research is needed to explore whether vitamin D supplements could prevent the risk of respiratory failure in patients with SARS-Cov-2 infection, he stressed.

In the meantime, Gennari said: “I believe that, particularly in the winter season (when the solar ultraviolet-B (UVB) radiation exposure does not allow the skin to synthesize vitamin D in most countries), the use of vitamin D supplementation and correction of vitamin D deficiency might be of major relevance for the reduction of the clinical burden of the ongoing and future outbreaks of SARS-CoV-2 infection.

Invited to comment, David Meltzer, MD, PhD, chief of hospital medicine at University of Chicago Medicine, Illinois, who was not involved with the study, agrees.

“I think this body of work suggests that people should be taking supplements if they cannot increase sun exposure on a sustained basis,” Meltzer said. “The abstract supports multiple prior findings that suggest that higher vitamin D levels are associated with improved outcomes.”

And JoAnn E. Manson, MD, DrPH, of Harvard Medical School and Brigham and Women’s Hospital, who was not involved with the research but has spoken about the topic in a video report for Medscape, said: “We know from several studies that a low vitamin D level is associated with a higher risk of having COVID-19 and severe illness, but correlation does not prove causation.”

“I think that improving vitamin D status is a promising way to reduce the risk of severe illness, but we need randomized controlled trials to prove cause and effect,” she told Medscape Medical News.

103 patients with severe COVID-19, 52 with mild COVID-19, 206 controls

Gennari said several lines of evidence suggest that vitamin D deficiency might be a risk factor for COVID-19 severity.

Countries with lower average levels of vitamin D or lower UVB radiation exposure have higher COVID-19 mortality, and “demographic groups known to be at higher risk of vitamin D deficiency (such as black individuals, the elderly, nursing home residents, and those with obesity and diabetes) are at high risk of COVID-19 hospitalization/mortality, he noted.

There is a high prevalence of vitamin D deficiency in Italy, where mortality rates from COVID-19 have been particularly high.

To examine the relationship between vitamin D levels and COVID-19 severity/mortality, the researchers studied three groups:

• 103 symptomatic patients with COVID-19 with respiratory insufficiency who were admitted to a Milan hospital from March 9 to April 30.
• 52 patients with mild COVID-19, recruited from patients and staff from a nearby nursing home who had a positive test for COVID-19.
• 206 healthy controls, matched 2:1 with symptomatic patients of the same age, weight, and gender, from 3174 patients who had vitamin D measured during a routine check-up from January to March 2020.

Patients in the hospitalized group had lower mean vitamin D levels (18.2 ng/mL) than those with mild COVID-19 (30.3 ng/mL) or those in the control group (25.4 ng/mL).

Patients with symptomatic versus mild COVID-19 were slightly older and more likely to have at least one comorbidity and less likely to be taking a vitamin D supplement at baseline (30% vs 79%).

Among symptomatic patients, mean vitamin D levels were inversely associated with interleukin (IL)-6 and C-reactive protein, “both of which are a direct expression of the inflammatory status,” Gennari noted.

About half of the hospitalized patients (49) were admitted to a ward and discharged after a mean stay of 16 days (none died).

The other 54 hospitalized patients were admitted to the intensive care unit with severe acute respiratory distress; 38 patients received continuous positive airway pressure (CPAP) and 16 patients received endotracheal intubation.

Of the 54 patients admitted to ICU, 19 patients died from respiratory distress after a mean of 19 days, “consistent with the literature,” and the other 35 patients were discharged after a mean of 21 days.

Patients with severe COVID-19 who were admitted to the ICU, as opposed to a ward, were more likely to be male, have at least one comorbidity, have higher baseline IL-6 levels and neutrophil counts, and lower lymphocyte and platelet counts.

They also had lower mean vitamin D levels (14.4 vs 22.4 ng/mL) and were more likely to have vitamin D deficiency (vitamin D <20 ng/mL; 80% vs. 45%).  

Patients admitted to ICU who died had lower baseline vitamin D levels than those who survived (13.2 vs. 19.3 ng/mL).

Vitamin D levels were inversely associated with respiratory distress requiring ICU admission (odds ratio, 1.06; P = .038) and with mortality (OR, 1.18, P = 029), independent of IL-6 levels and other comorbidities.

“That vitamin D levels are associated with improved outcomes independent of IL-6 could reflect that IL-6 is an imperfect measure of the inflammatory process or that vitamin D is related to outcomes for other reasons, such as enhancement of innate or adaptive immunity,” said Meltzer.

He added that “this is not to exclude the possibility that vitamin D has important immunomodulatory effects.”

Gennari, Meltzer, and Manson have reported no relevant financial relationships.

Early on in the COVID-19 pandemic, clinicians intubated many patients with respiratory insufficiency because of concern for aerosolization with other methods.

“We were concerned that, if we put them on high-flow nasal cannula or a noninvasive ventilation, that we would create aerosols that would then be a risk to clinicians,” Meghan Lane-Fall, MD, MSHP, FCCM, said at a Society for Critical Care Medicine virtual meeting called COVID-19: What’s Next. “However, we’ve gotten much more comfortable with infection control. We’ve gotten much more comfortable with controlling these aerosols, with making sure that our clinicians are protected with the appropriate protective equipment. We’ve also realized that patients who end up becoming intubated have really poor outcomes, so we’ve looked at our practice critically and tried to figure out how to support patients noninvasively when that’s possible.”
 

Respiratory support options

According to Dr. Lane-Fall, an associate professor of anesthesiology and critical care at the University of Pennsylvania, Philadelphia, there are two basic types of respiratory support in patients with moderate, severe, or critical COVID-19: noninvasive and invasive. Noninvasive options include CPAP or BiPAP which can be delivered through nasal pillows, masks, and helmets, as well as high-flow nasal oxygen. Invasive options include endotracheal intubation, tracheostomy, and extracorporeal membrane oxygenation (ECMO), usually the veno-venous (VV) form. “But it’s uncommon to need VV ECMO, even in patients who have critical COVID-19,” she said.

Factors that favor noninvasive ventilation include stably high oxygen requirements, normal mental status, ward location of care, and moderate to severe COVID-19. Factors that favor invasive ventilation include someone who’s deteriorating rapidly, “whose oxygen requirements aren’t stable or who is cardiopulmonary compromised,” said Dr. Lane-Fall, who is also co–medical director of the Trauma Surgery Intensive Care Unit at Penn Presbyterian Medical Center, also in Philadelphia. Other factors include the need for other invasive procedures such as surgery or if they have severe to critical COVID-19, “not just pneumonia, but [illness that’s] progressing into [acute respiratory distress syndrome],” she said.

Indications for urgent endotracheal intubation as opposed to giving a trial of noninvasive ventilation or high-flow nasal oxygen include altered mental status, inability to protect airway, copious amounts of secretions, a Glasgow Coma Scale score of less than 8, severe respiratory acidosis, hypopnea or apnea, shock, or an inability to tolerate noninvasive support. “This is a relative contraindication,” Dr. Lane-Fall said. “I’ve certainly talked people through the BiPAP mask or the helmet. If you tell a patient, ‘I don’t want to have to put in a breathing tube; I want to maintain you on this,’ often they’ll be able to work through it.”
 

Safety precautions

Aerosolizing procedures require attention to location, personnel, and equipment, including personal protective equipment (PPE), said Dr. Lane-Fall, who is an anesthesiologist by training. “When you are intubating someone, whether they have COVID-19 or not, you are sort of in the belly of the beast,” she said. “You are very exposed to secretions that occur at the time of endotracheal intubation. That’s why it’s important for us to have PPE and barriers to protect ourselves from potential exposure to aerosols during the care of patients with COVID-19.”

In February 2020, the non-for-profit Anesthesia Patient Safety Foundation published recommendations for airway management in patients with suspected COVID-19. A separate guidance was published the British Journal of Anaesthesiology based on emergency tracheal intubation in 202 patients with COVID-19 in Wuhan, China. “The idea here is that you want to intubate under controlled conditions,” said Dr. Lane-Fall, who is an author of the guidance. “You want to use the most experienced operator. You want to have full PPE, including an N95 mask, or something more protective like a powered air purifying respirator or an N95 mask with a face shield. You want the eyes, nose, and mouth of the operator covered completely.”

CPR, another aerosolizing procedure, requires vigilant safety precautions as well. “We struggled with this a little bit at our institution, because our inclination as intensivists when someone is pulseless is to run into the room and start chest compressions and to start resuscitation,” Dr. Lane-Fall said. “But the act of chest compression itself can create aerosols that can present risk to clinicians. We had to tell our clinicians that they have to put on PPE before they do CPR. The buzz phrase here is that there is no emergency in a pandemic. The idea here is that the good of that one patient is outweighed by the good of all the other patients that you could care for if you didn’t have COVID-19 as a clinician. So we have had to encourage our staff to put on PPE first before attending to patients first, even if it delays patient care. Once you have donned PPE, when you’re administering CPR, the number of staff should be minimized. You should have a compressor, and someone to relieve the compressor, and a code leader, someone tending to the airway. But in general, anyone who’s not actively involved should not be in the room.”
 

Risks during extubation

Extubation of COVID-19 patients is also an aerosolizing procedure not just because you’re pulling an endotracheal tube out of the airway but because coughing is a normal part of extubation. “We’ve had to be careful with how we approach extubation in COVID-19 patients,” Dr. Lane-Fall said. “Ideally you’re doing this in a negative pressure environment. We have also had to use full PPE, covering the eyes and face, and putting on a gown for precaution.”

Reintubation of COVID-19 patients is not uncommon. She and her colleagues at Penn Medicine created procedures for having intubators at the ready outside the room in case the patient were to decompensate clinically. “Another thing we learned is that it’s useful to do a leak test prior to extubation, because there may be airway edema related to prolonged intubation in these patients,” Dr. Lane-Fall said. “We found that, if a leak is absent on checking the cuff leak, the use of steroids for a day or 2 may help decrease airway edema. That improves the chances of extubation success.”
 

Strategies for aerosol containment

She concluded her remarks by reviewing airway control adjuncts and clinician safety. This includes physically isolating COVID-19 patients in negative pressure rooms and avoiding and minimizing aerosols, including the use of rapid intubation, “where we induce anesthesia for intubation but we don’t bag-mask the patient because that creates aerosols,” she said. The Anesthesia Patient Safety Foundation guidelines advocate for the use of video laryngoscopy so that you can visualize the glottis easily “and make sure that you successfully intubate the glottis and not the esophagus,” she said.

A smart strategy for aerosol containment is to use the most experienced laryngoscopist available. “If you are in a teaching program, ideally you’re using your most experienced resident, or you’re using fellows or attending physicians,” Dr. Lane-Fall said. “This is not the space for an inexperienced learner.”

Another way to make intubation faster and easier in COVID-19 patients is to use an intubation box, which features a plexiglass shield that enables the intubator to use their hands to get in the patient’s airway while being protected from viral droplets generated during intubation. The box can be cleaned after each use. Blueprints for an open source intubation box can be found at http://www.intubationbox.com.

Expert view on aerosol containment in COVID-19

“While there is a dearth of evidence from controlled trials, recommendations mentioned in this story are based on the best available evidence and are in agreement with guidelines from several expert groups,” said David L. Bowton, MD, FCCP, FCCM, of the department of anesthesiology at Wake Forest Baptist Health in Winston-Salem, NC. “The recommendation of Dr. Lane-Fall’s that is perhaps most controversial is the use of an intubation box. Multiple designs for these intubation/aerosol containment devices have been proposed, and the data supporting their ease of use and efficacy has been mixed [See Anaesthesia 2020;75(8):1014-21 and Anaesthesia. 2020. doi: 10.1111/anae.15188]. While bag valve mask ventilation should be avoided if possible, it may be a valuable rescue tool in the severely hypoxemic patient when used with two-person technique to achieve a tight seal and a PEEP valve and an HME over the exhalation port to minimize aerosol spread.

“It cannot be stressed enough that the most skilled individual should be tasked with intubating the patient and as few providers as possible [usually three] should be in the room and have donned full PPE. Negative pressure rooms should be used whenever feasible. Noninvasive ventilation appears safer from an infection control standpoint than initially feared and its use has become more widespread. However, noninvasive ventilation is not without its hazards, and Dr. Lane-Fall’s enumeration of the patient characteristics applicable to the selection of patients for noninvasive ventilation are extremely important. At our institution, the use of noninvasive ventilation and especially high-flow oxygen therapy has increased. Staff have become more comfortable with the donning and doffing of PPE.”

Early on in the COVID-19 pandemic, clinicians intubated many patients with respiratory insufficiency because of concern for aerosolization with other methods.

“We were concerned that, if we put them on high-flow nasal cannula or a noninvasive ventilation, that we would create aerosols that would then be a risk to clinicians,” Meghan Lane-Fall, MD, MSHP, FCCM, said at a Society for Critical Care Medicine virtual meeting called COVID-19: What’s Next. “However, we’ve gotten much more comfortable with infection control. We’ve gotten much more comfortable with controlling these aerosols, with making sure that our clinicians are protected with the appropriate protective equipment. We’ve also realized that patients who end up becoming intubated have really poor outcomes, so we’ve looked at our practice critically and tried to figure out how to support patients noninvasively when that’s possible.”

Almost a quarter of adults in the United States are very concerned about access to health care during the COVID-19 pandemic, according to the results of a survey conducted Aug. 7-26.

Nationally, 23.8% of respondents said that they were very concerned about being able to receive care during the pandemic, and another 27.4% said that they were somewhat concerned. Just under a quarter, 24.3%, said they were not very concerned, while 20.4% were not at all concerned, the COVID-19 Consortium for Understanding the Public’s Policy Preferences Across States reported after surveying 21,196 adults.

At the state level, Mississippi had the most adults (35.5%) who were very concerned about their access to care, followed by Texas (32.7%) and Nevada (32.4%). The residents of Montana were least likely (10.5%) to be very concerned, with Vermont next at 11.6% and Wyoming slightly higher at 13.8%. Montana also had the highest proportion of adults, 30.2%, who were not at all concerned, the consortium’s data show.

When asked about getting the coronavirus themselves, 67.8% of U.S. adults came down on the concerned side (33.3% somewhat and 34.5% very concerned) versus 30.8% who were not concerned (18.6% were not very concerned; 12.2% were not concerned at all.). Respondents’ concern was higher for their family members’ risk of getting coronavirus: 30.2% were somewhat concerned and 47.6% were very concerned, the consortium said.

Among many other topics, respondents were asked how closely they had followed recommended health guidelines in the last week, with the two extremes shown here:

• Avoiding contact with other people: 49.3% very closely, 4.8% not at all closely.
• Frequently washing hands: 74.7% very, 1.6% not at all.
• Disinfecting often-touched surfaces: 54.4% very, 4.3% not at all.
• Wearing a face mask in public: 75.7% very, 3.5% not at all.

The consortium is a joint project of the Network Science Institute of Northeastern University; the Shorenstein Center on Media, Politics, and Public Policy of Harvard University; Harvard Medical School; the School of Communication and Information at Rutgers University; and the department of political science at Northwestern University. The project is supported by grants from the National Science Foundation.

Respiratory virus seasons usually follow a fairly well-known pattern. Enterovirus 68 (EV-D68) is a summer-to-early fall virus with biennial peak years. Rhinovirus (HRv) and adenovirus (Adv) occur nearly year-round but may have small upticks in the first month or so that children return to school. Early in the school year, upper respiratory infections from both HRv and Adv and viral sore throats from Adv are common, with conjunctivitis from Adv outbreaks in some years. October to November is human parainfluenza (HPiV) 1 and 2 season, often presenting as croup. Human metapneumovirus infections span October through April. In late November to December, influenza begins, usually with an A type, later transitioning to a B type in February through April. Also in December, respiratory syncytial virus (RSV) starts, characteristically with bronchiolitis presentations, peaking in February to March and tapering off in May. In late March to April, HPiV 3 also appears for 4-6 weeks.

Will 2020-2021 be different?

Summer was remarkably free of expected enterovirus activity, suggesting that the seasonal parade may differ this year. Remember that the 2019-2020 respiratory season suddenly and nearly completely stopped in March because of social distancing and lockdowns needed to address the SARS-CoV-2 pandemic.

The mild influenza season in the southern hemisphere suggests that our influenza season also could be mild. But perhaps not – most southern hemisphere countries that are surveyed for influenza activities had the most intense SARS-CoV-2 mitigations, making the observed mildness potentially related more to social mitigation than less virulent influenza strains. If so, southern hemisphere influenza data may not apply to the United States, where social distancing and masks are ignored or used inconsistently by almost half the population.

Further, the stop-and-go pattern of in-person school/college attendance adds to uncertainties for the usual orderly virus-specific seasonality. The result may be multiple stop-and-go “pop-up” or “mini” outbreaks for any given virus potentially reflected as exaggerated local or regional differences in circulation of various viruses. The erratic seasonality also would increase coinfections, which could present with more severe or different symptoms.
 

SARS-CoV-2’s potential interaction

Will the relatively mild presentations for most children with SARS-CoV-2 hold up in the setting of coinfections or sequential respiratory viral infections? Could SARS-CoV-2 cause worse/more prolonged symptoms or more sequelae if paired simultaneously or in tandem with a traditional respiratory virus? To date, data on the frequency and severity of SARS-CoV-2 coinfections are conflicting and sparse, but it appears that non-SARS-CoV-2 viruses can be involved in 15%-50% pediatric acute respiratory infections.^1,2

However, it may not be important to know about coinfecting viruses other than influenza (can be treated) or SARS-CoV-2 (needs quarantine and contact tracing), unless symptoms are atypical or more severe than usual. For example, a young child with bronchiolitis is most likely infected with RSV, but HPiV, influenza, metapneumovirus, HRv, and even SARS-CoV-2 can cause bronchiolitis. Even so, testing outpatients for RSV or non-influenza is not routine or even clinically helpful. Supportive treatment and restriction from daycare attendance are sufficient management for outpatient ARIs whether presenting as bronchiolitis or not. The worry is that SARS-CoV-2 as a coinfecting agent may not provide an identifiable clinical signal as primary or coinfecting ARI pathogen.
 

Considerations for SARS-CoV-2 testing: Outpatient bronchiolitis

If a child presents with classic bronchiolitis but has above moderate to severe symptoms, is SARS-CoV-2 a consideration? Perhaps, if SARS-CoV-2 acts similarly to non-SARS-CoV-2s.

A recent report from the 30th Multicenter Airway Research Collaboration (MARC-30) surveillance study (2007-2014) of children hospitalized with clinical bronchiolitis evaluated respiratory viruses, including RSV and the four common non-SARS coronaviruses using molecular testing.³ Among 1,880 subjects, a CoV (alpha CoV: NL63 or 229E, or beta CoV: KKU1 or OC43) was detected in 12%. Yet most had only RSV (n = 1,661); 32 had only CoV (n = 32). But note that 219 had both.

Bronchiolitis subjects with CoV were older – median 3.7 (1.4-5.8) vs. 2.8 (1.9-7.2) years – and more likely male than were RSV subjects (68% vs. 58%). OC43 was most frequent followed by equal numbers of HKU1 and NL63, while 229E was the least frequent. Medical utilization and severity did not differ among the CoVs, or between RSV+CoV vs. RSV alone, unless one considered CoV viral load as a variable. ICU use increased when the polymerase chain reaction cycle threshold result indicated a high CoV viral load.

These data suggest CoVs are not infrequent coinfectors with RSV in bronchiolitis – and that SARS-CoV-2 is the same. Therefore, a bronchiolitis presentation doesn’t necessarily take us off the hook for the need to consider SARS-CoV-2 testing, particularly in the somewhat older bronchiolitis patient with more than mild symptoms.
 

Considerations for SARS-CoV-2 testing: Outpatient influenza-like illness

In 2020-2021, the Centers for Disease Control and Prevention recommends considering empiric antiviral treatment for ILIs (fever plus either cough or sore throat) based upon our clinical judgement, even in non-high-risk children.⁴

While pediatric COVID-19 illnesses are predominantly asymptomatic or mild, a febrile ARI is also a SARS-CoV-2 compatible presentation. So, if all we use is our clinical judgment, how do we know if the febrile ARI is due to influenza or SARS-CoV-2 or both? At least one study used a highly sensitive and specific molecular influenza test to show that the accuracy of clinically diagnosing influenza in children is not much better than flipping a coin and would lead to potential antiviral overuse.⁵

So, it seems ideal to test for influenza when possible. Point-of-care (POC) tests are frequently used for outpatients. Eight POC Clinical Laboratory Improvement Amendments (CLIA)–waived kits, some also detecting RSV, are available but most have modest sensitivity (60%-80%) compared with lab-based molecular tests.⁶ That said, if supplies and kits for one of the POC tests are available to us during these SARS-CoV-2 stressed times (back orders seem more common this year), a positive influenza test in the first 48 hours of symptoms confirms the option to prescribe an antiviral. Yet how will we have confidence that the febrile ARI is not also partly due to SARS-CoV-2? Currently febrile ARIs usually are considered SARS-CoV-2 and the children are sent for SARS-CoV-2 testing. During influenza season, it seems we will need to continue to send febrile outpatients for SARS-CoV-2 testing, even if POC influenza positive, via whatever mechanisms are available as time goes on.

We expect more rapid pediatric testing modalities for SARS-CoV-2 (maybe even saliva tests) to become available over the next months. Indeed, rapid antigen tests and rapid molecular tests are being evaluated in adults and seem destined for CLIA waivers as POC tests, and even home testing kits. Pediatric approvals hopefully also will occur. So, the pathways for SARS-CoV-2 testing available now will likely change over this winter. But be aware that supplies/kits will be prioritized to locations within high need areas and bulk purchase contracts. So POC kits may remain scarce for practices, meaning a reference laboratory still could be the way to go for SARS-CoV-2 for at least the rest of 2020. Reference labs are becoming creative as well; one combined detection of influenza A, influenza B, RSV, and SARS-CoV-2 into one test, and hopes to get approval for swab collection that can be done by families at home and mailed in.

 

Summary

Expect variations on the traditional parade of seasonal respiratory viruses, with increased numbers of coinfections. Choosing the outpatient who needs influenza testing is the same as in past years, although we have CDC permissive recommendations to prescribe antivirals for any outpatient ILI within the first 48 hours of symptoms. Still, POC testing for influenza remains potentially valuable in the ILI patient. The choice of whether and how to test for SARS-CoV-2 given its potential to be a primary or coinfecting agent in presentations linked more closely to a traditional virus (e.g. RSV bronchiolitis) will be a test of our clinical judgement until more data and easier testing are available. Further complicating coinfection recognition is the fact that many sick visits occur by telehealth and much testing is done at drive-through SARS-CoV-2 testing facilities with no clinician exam. Unless we are liberal in SARS-CoV-2 testing, detecting SARS-CoV-2 coinfections is easier said than done given its usually mild presentation being overshadowed by any coinfecting virus.

But understanding who has SARS-CoV-2, even as a coinfection, still is essential in controlling the pandemic. We will need to be vigilant for evolving approaches to SARS-CoV-2 testing in the context of symptomatic ARI presentations, knowing this will likely remain a moving target for the foreseeable future.

Anthony Fauci, MD, highlighting the latest COVID-19 developments on Friday, said, “It is now clear that about 40%-45% of infections are asymptomatic.”

NIH

Asymptomatic carriers can account for a large proportion — up to 50% — of virus transmissions, Fauci, director of the National Institute of Allergy and Infectious Diseases, told a virtual crowd of critical care clinicians gathered by the Society of Critical Care Medicine.

Such transmissions have made response strategies, such as contact tracing, extremely difficult, he said.

Lew Kaplan, MD, president of SCCM, told Medscape Medical News after the presentation: “That really supports the universal wearing of masks and the capstone message from that – you should protect one another.

“That kind of social responsibility that sits within the public health domain to me is as important as the vaccine candidates and the science behind the receptors. It underpins the necessary relationship and the interdependence of the medical community with the public,” Kaplan added.

Fauci’s plenary led the SCCM’s conference, “COVID-19: What’s Next/Preparing for the Second Wave,” running today and Saturday.
 

Why U.S. response lags behind Spain and Italy

“This virus has literally exploded upon the planet in a pandemic manner which is unparalleled to anything we’ve seen in the last 102 years since the pandemic of 1918,” Fauci said.

“Unfortunately, the United States has been hit harder than any other country in the world, with 6 million reported cases.”

He explained that in the European Union countries the disease spiked early on and returned to a low baseline. “Unfortunately for them,” Fauci said, “as they’re trying to open up their economy, it’s coming back up.”

The United States, he explained, plateaued at about 20,000 cases a day, then a surge of cases in Florida, California, Texas, and Arizona brought the cases to 70,000 a day. Now cases have returned to 35,000-40,000 a day.

The difference in the trajectory of the response, he said, is that, compared with Spain and Italy for example, the United States has not shut down mobility in parks, outdoor spaces, and grocery stores nearly as much as some European countries did.

He pointed to numerous clusters of cases, spread from social or work gatherings, including the well-known Skagit County Washington state choir practice in March, in which a symptomatic choir member infected 87% of the 61 people rehearsing.
 

Vaccine by end of the year

As for a vaccine timeline, Fauci told SCCM members, “We project that by the end of this year, namely November/December, we will know if we have a safe and effective vaccine and we are cautiously optimistic that we will be successful, based on promising data in the animal model as well as good immunological data that we see from the phase 1 and phase 2 trials.”

However, also on Friday, Fauci told MSNBC’s Andrea Mitchell that a sense of normalcy is not likely before the middle of next year.

“By the time you mobilize the distribution of the vaccinations, and you get the majority, or more, of the population vaccinated and protected, that’s likely not going to happen [until] the mid- or end of 2021,” he said.

According to the Centers for Disease Control and Prevention (CDC) case tracker, as of Thursday, COVID-19 had resulted in more than 190,000 deaths overall and more than 256,000 new cases in the United States in the past 7 days.

Fauci has warned that the next few months will be critical in the virus’ trajectory, with the double onslaught of COVID-19 and the flu season.

On Thursday, Fauci said, “We need to hunker down and get through this fall and winter because it’s not going to be easy.”

Fauci remains a top trusted source in COVID-19 information, poll numbers show.

A Kaiser Family Foundation poll released Thursday found that 68% of US adults had a fair amount or a great deal of trust that Fauci would provide reliable information on COVID-19, just slightly more that the 67% who said they trust the CDC information. About half (53%) say they trust Deborah Birx, MD, the coordinator for the White House Coronavirus Task Force, as a reliable source of information.

The poll also found that 54% of Americans said they would not get a COVID-19 vaccine if one was approved by the US Food and Drug Administration before the November election and was made available and free to all who wanted it.

Kaplan and Fauci report no relevant financial relationships.

Anthony Fauci, MD, highlighting the latest COVID-19 developments on Friday, said, “It is now clear that about 40%-45% of infections are asymptomatic.”

Asymptomatic carriers can account for a large proportion — up to 50% — of virus transmissions, Fauci, director of the National Institute of Allergy and Infectious Diseases, told a virtual crowd of critical care clinicians gathered by the Society of Critical Care Medicine.

Such transmissions have made response strategies, such as contact tracing, extremely difficult, he said.

Lew Kaplan, MD, president of SCCM, told Medscape Medical News after the presentation: “That really supports the universal wearing of masks and the capstone message from that – you should protect one another.

“That kind of social responsibility that sits within the public health domain to me is as important as the vaccine candidates and the science behind the receptors. It underpins the necessary relationship and the interdependence of the medical community with the public,” Kaplan added.

Fauci’s plenary led the SCCM’s conference, “COVID-19: What’s Next/Preparing for the Second Wave,” running today and Saturday.
 

Why U.S. response lags behind Spain and Italy

“This virus has literally exploded upon the planet in a pandemic manner which is unparalleled to anything we’ve seen in the last 102 years since the pandemic of 1918,” Fauci said.

“Unfortunately, the United States has been hit harder than any other country in the world, with 6 million reported cases.”

He explained that in the European Union countries the disease spiked early on and returned to a low baseline. “Unfortunately for them,” Fauci said, “as they’re trying to open up their economy, it’s coming back up.”

The United States, he explained, plateaued at about 20,000 cases a day, then a surge of cases in Florida, California, Texas, and Arizona brought the cases to 70,000 a day. Now cases have returned to 35,000-40,000 a day.

The difference in the trajectory of the response, he said, is that, compared with Spain and Italy for example, the United States has not shut down mobility in parks, outdoor spaces, and grocery stores nearly as much as some European countries did.

He pointed to numerous clusters of cases, spread from social or work gatherings, including the well-known Skagit County Washington state choir practice in March, in which a symptomatic choir member infected 87% of the 61 people rehearsing.
 

Vaccine by end of the year

As for a vaccine timeline, Fauci told SCCM members, “We project that by the end of this year, namely November/December, we will know if we have a safe and effective vaccine and we are cautiously optimistic that we will be successful, based on promising data in the animal model as well as good immunological data that we see from the phase 1 and phase 2 trials.”

A few months ago, I published a short thought piece on the use of “sitters” with patients who were COVID-19 positive, or patients under investigation. In it, I recommended the use of telesitters for those who normally would warrant a human sitter, to decrease the discomfort of sitting in full personal protective equipment (PPE) (gown, mask, gloves, etc.) while monitoring a suicidal patient.

I received several queries, which I want to address here. In addition, I want to draw from my Army days in terms of the claustrophobia often experienced with PPE.

The first of the questions was about evidence-based practices. The second was about the discomfort of having sitters sit for many hours in the full gear.

I do not know of any evidence-based practices, but I hope we will develop them.

I agree that spending many hours in full PPE can be discomforting, which is why I wrote the essay.

As far as lessons learned from the Army time, I briefly learned how to wear a “gas mask” or Mission-Oriented Protective Posture (MOPP gear) while at Fort Bragg. We were run through the “gas chamber,” where sergeants released tear gas while we had the mask on. We were then asked to lift it up, and then tearing and sputtering, we could leave the small wooden building.

We wore the mask as part of our Army gear, usually on the right leg. After that, I mainly used the protective mask in its bag as a pillow when I was in the field.

Fast forward to August 1990. I arrived at Camp Casey, near the Korean demilitarized zone. Four days later, Saddam Hussein invaded Kuwait. The gas mask moved from a pillow to something we had to wear while doing 12-mile road marches in “full ruck.” In full ruck, you have your uniform on, with TA-50, knapsack, and weapon. No, I do not remember any more what TA-50 stands for, but essentially it is the webbing that holds your bullets and bandages.

Many could not tolerate it. They developed claustrophobia – sweating, air hunger, and panic. If stationed in the Gulf for Operation Desert Storm, they were evacuated home.

I wrote a couple of short articles on treatment of gas mask phobia.^1,2 I basically advised desensitization. Start by watching TV in it for 5 minutes. Graduate to ironing your uniform in the mask. Go then to shorter runs. Work up to the 12-mile road march.

In my second tour in Korea, we had exercises where we simulated being hit by nerve agents and had to operate the hospital for days at a time in partial or full PPE. It was tough but we did it, and felt more confident about surviving attacks from North Korea.

So back to the pandemic present. I have gotten more used to my constant wearing of a surgical mask. I get anxious when I see others with masks below their noses. I almost panic when others do not wear their masks at all, such as the lady today who was brushing her teeth in the shared ladies’ restroom.

The pandemic is not going away anytime soon, in my opinion. Furthermore, there are other viruses that are worse, such as Ebola. It is only a matter of time.

So, let us train with our PPE. If health care workers cannot tolerate them, use desensitization- and anxiety-reducing techniques to help them.

There are no easy answers here, in the time of the COVID pandemic. However, we owe it to ourselves, our patients, and society to do the best we can.

Growth in new pediatric COVID-19 cases has evened out in recent weeks, but children now represent 10% of all COVID-19 cases in the United States, and that measurement has been rising throughout the pandemic, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

The cumulative number of child COVID-19 cases was 549,432 for the week ending Sept. 10, an increase of 7.0% (36,017 cases) from the week before, the AAP and the CHA said in the report, based on data from 49 states (New York City is included but not New York state), the District of Columbia, Puerto Rico, and Guam.

The weekly percentage of increase in the number of new cases has not reached double digits since early August and has been no higher than 7.8% over the last 3 weeks. The number of child COVID-19 cases, however, has finally reached 10% of the total for Americans of all ages, which stands at 5.49 million in the jurisdictions included in the report, the AHA and CHA reported.

Measures, however, continue to show low levels of severe illness in children, they noted, including the following:

• Child cases as a proportion of all COVID-19 hospitalizations: 1.7%.
• Hospitalization rate for children: 1.8%.
• Child deaths as a proportion of all deaths: 0.07%.
• Percent of child cases resulting in death: 0.01%.

The number of cumulative cases per 100,000 children is now up to 728.5 nationally, with a range by state that goes from 154.0 in Vermont to 1,670.3 in Tennessee, which is one of only two states reporting cases in those aged 0-20 years as children (the other is South Carolina). The age range for children is 0-17 or 0-19 for most other states, although Florida uses a range of 0-14, the report notes.

Other than Tennessee, there are 10 states with overall rates higher than 1,000 COVID-19 cases per 100,000 children, and there are nine states with cumulative totals over 15,000 cases (California is the highest with just over 75,000), according to the report.
