In 2014, when the Food and Drug Administration found serious problems with a life-sustaining heart pump, its warning letter to the manufacturer threatened to notify other federal health agencies about the inspection’s findings.

But for years, no such alert ever went out. Instead, the agency added the warning letter to an online database alongside thousands of others, following its typical procedures, an FDA spokesperson said.

Agencies such as the Centers for Medicare & Medicaid Services and the U.S. Department of Veterans Affairs went on paying to implant the HeartWare Ventricular Assist Device, or HVAD, in new patients even though federal inspectors had found problems with the device linked to patient deaths and injuries.

Taxpayer dollars continued to flow to the original device maker, HeartWare, and then to the company that acquired it in 2016, Medtronic, for 7 years while the issues raised in the warning letter remained unresolved.

If crucial safety information in FDA warning letters doesn’t make it to other arms of the government responsible for deciding which medical devices to pay for, experts said patients are the ones put at risk.

“It’s clearly a breakdown of communication,” said Dr. Rita Redberg, a cardiologist at the University of California, San Francisco, who researches medical device safety and regulation. “It’s not just the money, obviously. It’s people’s lives.”

The FDA acknowledged that it doesn’t directly notify other agencies when it issues warning letters, pointing instead to its online database, which is accessible to both government officials and the public. “The FDA’s decisions are intended to be patient-centric with the health and safety of device users as our highest priority,” the agency spokesperson said in an email.

The HeartWare letter was removed from the public database about 2 years ago, even though the problems remained unresolved and patients were still receiving implants. The database clears out letters that are more than 5 years old.

CMS, which oversees the Medicare and Medicaid programs, would not say why it continued paying for a device that didn’t meet government standards. It directed questions about the HeartWare warning letter to the FDA. “CMS does not have oversight of the manufacturing and related safety assessments of a medical device manufacturer,” a spokesperson said in an email.

The spokesperson noted that CMS requires heart pump patients to have specialized medical teams managing their care, which should monitor FDA communications regarding safety of devices.

CMS doesn’t track data on devices by manufacturer, so it’s essentially impossible to calculate its total spending on HVADs. One 2018 medical journal study found that Medicare and Medicaid paid for more than half the cost of all heart pump implants from 2009 to 2014. If that rate of spending continued, CMS may have spent more than $400 million on implanting HVADs since 2014.

A spokesperson for the VA said his agency was never notified about the HeartWare warning letter. The VA paid HeartWare and Medtronic more than $3 million after the FDA issued the letter in 2014. It offered this explanation for why: “It’s important to note that FDA Warning Letters are notifications issued to manufacturers found to be in significant violation of federal regulations. They are not product recalls.”

In the case of the HVAD, the FDA’s failure to make sure its warning reached beyond the manufacturer may have had life-and-death consequences.

In August, ProPublica reported that federal inspectors continued finding problems at the HVAD’s manufacturing plant for years. Meanwhile, the FDA received thousands of reports of suspicious deaths and injuries and more than a dozen high-risk safety alerts from the manufacturer.

The documents detailed one horrifying device failure after another. A father of four died after his device suddenly failed and his teenage daughter couldn’t resuscitate him. Another patient’s heart tissue was charred after a pump short-circuited and overheated. A teenager died after vomiting blood as his mother struggled to restart a defective pump.

In June, Medtronic ended sales and implants of the device, citing new data that showed patients with HVADs had a higher rate of deaths and strokes than those with a competing heart pump.

Medtronic declined to comment for this story. It has previously said it believed that after the 2014 warning letter the benefits of the HVAD still outweighed the risks for patients with severe heart failure.

Experts said the lack of communication between federal agencies when serious device problems are found is baffling but not surprising. It fits a broader trend of device regulators focusing more on evaluating new products than monitoring the ones already on the market.

“The priority is to get more medical devices out there, paid for and getting used,” said Dr. Joseph Ross, a professor of medicine and public health at Yale University who studies medical device regulation.

Other U.S. health care regulators move more forcefully when providers and suppliers don’t meet the government’s minimum safety requirements for an extended period, putting patients at risk.

Take hospitals. When inspectors find a facility is not meeting safety standards, CMS can issue an immediate jeopardy citation and, if problems aren’t fixed, move to withhold federal payments, which make up substantial portions of most hospitals’ revenues. In the rare cases when hospitals don’t take sufficient action, CMS follows through and revokes funding.

Redberg, the UCSF cardiologist, said the lack of similar action for medical devices offers a clear “opportunity for improvement.” At minimum, the FDA could establish processes to directly inform other agencies when it issues warning letters and finds serious problems with devices being sold in the United States.

“If the agency’s mission is to protect public health, they would want to do these things and move quickly,” she said.

The damage to the heart caused by a myocardial infarction is not just a result of ischemia caused by the blocked artery but is also brought about by bleeding in the myocardium after the artery has been opened, a new study suggests.

This observation is leading to new approaches to limiting infarct size and treating MI.

“In MI treatment, we have always focused on opening up the artery as quickly as possible to limit the myocardial damage caused by ischemia,” the study’s senior author, Rohan Dharmakumar, PhD, Indiana University, Indianapolis, told this news organization.

“We are pursuing a completely new approach focusing on limiting the damage after revascularization,” he said. “We are totally rethinking what a myocardial infarction is – what causes the injury and the time course of the injury – our results suggest that it’s not just ischemic damage and a lot of the harm is caused by hemorrhage after reperfusion.”

It has been known for many years that hemorrhage is often seen in the myocardium in large MIs, but it has not been established before now whether it contributes to the injury or not, Dr. Dharmakumar explained.

“This study was done to look at that – and we found that the hemorrhage drives a second layer of injury on top of the ischemia.”

Dr. Dharmakumar said this hemorrhage is part of the phenomenon known as reperfusion injury. “This has been known to exist for many years, but we haven’t fully understood all the factors contributing to it. Our results suggest that hemorrhage is a major component of reperfusion injury – probably the dominant factor,” he said.  

The researchers are now working on therapeutic approaches to try to prevent this hemorrhage and/or to minimize its effect.

“We are studying how hemorrhage drives damage and how to block these biological processes,” Dr. Dharmakumar said. “Our studies suggest that hemorrhage could account for up to half of the damage caused by a myocardial infarction. If we can limit that, we should be able to reduce the size of the infarct and this should translate into better long-term outcomes.

“I’m very excited about these results,” he added. “We are already seeing a remarkable improvement in animal models with some of the potential therapeutic approaches we are working on.”

The current study is published in the January 2022 issue of the Journal of the American College of Cardiology (JACC).

The authors explain that it is now recognized that reperfusion injury can contribute to increasing infarct size, which they refer to as “infarct surge.” Previous studies have also shown that reperfusion injury can contribute to as much as 50% of the final infarct size, but the factors contributing to the observed variability are not known, and previous attempts to limit infarct surge from reperfusion injury have failed.

They noted that after reperfusion, microvessels can remain obstructed, resulting in intramyocardial hemorrhage. They conducted the current study to investigate whether such hemorrhage causes expansion of the infarct.

They studied 70 patients with ST-segment elevation MI who were categorized with cardiovascular MRI to have intramyocardial hemorrhage or not following primary PCI, and for whom serial cardiac troponin measures were used to assess infarct size.

Results showed that while troponin levels were not different before reperfusion, patients with intramyocardial hemorrhage had significantly higher cardiac troponin levels after reperfusion and these levels peaked earlier than in patients without hemorrhage.

In animal models, those with intramyocardial hemorrhage had a more rapid expansion of myocardial necrosis than did those without hemorrhage, and within 72 hours of reperfusion, a fourfold greater loss in salvageable myocardium was evident in hemorrhagic MIs.

“We have shown that damage to the heart continues after revascularization as measured by rapidly increasing troponin levels in the hearts that have had a hemorrhage,” Dr. Dharmakumar said.

“Hemorrhage in the myocardium was associated with larger infarctions, and in infarcts causing the same area of myocardium to be at risk, those with hemorrhage after revascularization lost a lot more of the salvageable myocardium than those without hemorrhage,” he added.

Dr. Dharmakumar estimates that such hemorrhage occurs in about half of MIs after revascularization, with risk factors including male gender, anterior wall MIs, and smoking.

He pointed out that previous attempts to treat or prevent reperfusion injury have not been successful, probably because they have not been addressing the key mechanism. “We have not been looking at hemorrhage in this regard until now. This is because it is only recently that we have had the tools to be able to identify hemorrhage in the heart with the use of cardiac MRI.” 
 

Final frontier

In an accompanying editorial, Colin Berry, MBChB, University of Glasgow, and Borja Ibáñez, MD, Jiménez Díaz Foundation University Hospital, Madrid, said they applaud the investigators for providing new, mechanistic insights into a difficult clinical problem that has an unmet therapeutic need.

But they pointed out that it is difficult to completely dissect the impact of hemorrhage versus MI size on adverse remodeling, noting that it might be the case that more severe ischemia/reperfusion events are associated with large MI sizes and higher degree of hemorrhage.

However, they concluded that: “Intramyocardial hemorrhage represents the final frontier for preventing heart failure post-MI. It is readily detected using CMR, and clinical research of novel therapeutic approaches merits prioritization.”

Patients with complex coronary artery disease (CAD) – either three-vessel disease and/or left main disease – who also had heavy coronary artery calcification (CAC) had greater all-cause mortality 10 years after revascularization, compared with those without such lesions.

However, perhaps unexpectedly, patients with heavily calcified lesions (HCLs) had similar 10-year survival whether they had undergone coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI).

These findings from a post hoc analysis of the SYNTAX Extended Survival (SYNTAXES) study led by Hideyuki Kawashima, MD, PhD, National University of Ireland, Galway, and the University of Amsterdam, were published online Dec. 29, 2021, in JACC: Cardiovascular Interventions.

“There was an apparent lack of benefit at very long-term with CABG versus PCI in the presence of HCL,” Dr. Kawashima and corresponding author Patrick W. Serruys, MD, PhD, National University of Ireland and Imperial College London, summarized in a joint email to this news organization.

“Since HCLs – the final status of atherosclerosis and inflammation – reflect the aging process, complexity, and extensiveness of CAD, and comorbidity, it is possible that the currently available revascularization methods do not provide benefit in the prevention of long-term [10-year] mortality,” they suggested.  

In an accompanying editorial, Usman Baber, MD, commented that this study provides a “novel insight.”

Specifically, while patients without HCLs had significantly lower 10-year mortality with CABG versus PCI (18.8% vs. 26.0%; P = .003), an opposite trend was observed among those with HCLs (39.0% vs. 34.0%; P = .26; P int = .005).

The patients with HCLs had higher SYNTAX scores (30.8 vs. 22.4; P < .001) and more complex CAD, so their lack of 10-year mortality benefit with CABG “is somewhat unexpected and warrants further scrutiny,” added Dr. Baber, from the University of Oklahoma Health Sciences Center in Oklahoma City.

Dr. Serruys and Dr. Kawashima agreed that “this study highlights the need for further research on this topic focusing on this specific population with HCLs,” which were 30% of the patients with complex lesions who participated in SYNTAXES.
 

Consider factors beyond coronary anatomy

The current findings reinforce “the importance of considering not just coronary anatomy, but patient age and other comorbid factors when evaluating mode of revascularization,” said Dr. Baber.

“Coronary calcification is a strong factor in deciding between CABG versus PCI, as multiple studies have shown that CAC increases risk after PCI, even with contemporary safe stent platforms,” he explained in an email.

The current study suggests the adverse prognosis associated with CAC also persists for patients treated with CABG.

Dr. Baber said that, “for patients in whom PCI may not be feasible due to extensive and bulky coronary calcification, it is important to emphasize that the benefits of CABG (versus PCI) may not be as significant or durable.”

“The lack of benefit with CABG,” he added, “is likely due to comorbid factors that tend to increase in prevalence with vascular calcification (older age, peripheral arterial disease, renal impairment, etc).”

This study reinforces “the importance of not just considering coronary complexity, but also additional noncoronary factors that influence long-term prognosis in patients with advanced multivessel CAD,” Dr. Baber stressed.

More aggressive lipid-lowering or antithrombotic therapy may improve the prognosis for such patients, he suggested.

“In general,” Dr. Serruys and Dr. Kawashima similarly noted, “for short-/mid-term outcomes, CABG is preferred to PCI in patients with HCLs because of a higher rate of complete revascularization and less need for repeat revascularization.”

“Our findings at 10 years are in line with the general findings preferring CABG in mid and long term, whereas the benefit of very long-term follow-up might be more complex to capture and comprehend,” they concluded. “Whether HCLs require special consideration when deciding the mode of revascularization beyond their contribution to the SYNTAX score deserves further evaluation.

“Newer PCI technology or CABG methods may become a game-changer in the future,” they speculated.
 

Worse clinical outcomes

Heavy coronary calcification is associated with worse clinical outcomes after PCI or CABG, but to date, no trial has compared 10-year outcomes after PCI or CABG in patients with complex CAD with versus without HCLs.

To look at this, Dr. Kawashima and colleagues performed a subanalysis of patients in the SYNTAXES study. The original SYNTAX trial had randomized 1,800 patients with complex CAD who were eligible for either PCI or CABG 1:1 to these two treatments, with a 5-year follow-up, and SYNTAXES extended the follow-up to 10 years.  

Of the 1,800 patients, 532 (29.6%) had at least one HCL and the rest (70.4%) did not.

The median follow-up in SYNTAXES was 11.2 years overall and 11.9 years in survivors.

At baseline, compared with other patients, those with HCLs were older and had a lower body mass index and higher rates of insulin-treated diabetes, hypertension, previous cerebrovascular disease, peripheral vascular disease, chronic obstructive pulmonary disease, chronic kidney disease, and heart failure.

After adjusting for multiple variables, having a HCL was an independent predictor of greater risk of 10-year mortality (hazard ratio, 1.36; 95% confidence interval, 1.09-1.69; P = .006).

In patients without HCLs, mortality was significantly higher after PCI than CABG (HR, 1.44; 95% CI, 1.14-1.83; P = .003), whereas in those with HCLs, there was no significant difference (HR, 0.85; 95% CI, 0.64-1.13; P = .264).

The location of the HCL did not have any impact on 10-year mortality regardless of the assigned treatment.

Among patients with at least one HCL who underwent CABG, those with at least two HCLs had greater 10-year all-cause mortality than those with one HCL; this difference was not seen among patients with at least one HCL who underwent PCI.

The researchers acknowledge study limitations include that it was a post hoc analysis, so it should be considered hypothesis generating.

In addition, SYNTAX was conducted between 2005 and 2007, when PCI mainly used first-generation paclitaxel drug-eluting stents, so the findings may not be generalizable to current practice.

SYNTAXES was supported by the German Foundation of Heart Research. SYNTAX, during 0- to 5-year follow-up, was funded by Boston Scientific. Dr. Serruys reported receiving personal fees from SMT, Philips/Volcano, Xeltis, Novartis, and Meril Life. Dr. Kawashima reported no relevant financial relationships. Dr. Baber reported receiving honoraria and speaker fees from AstraZeneca, Biotronik, and Amgen.

Patients with complex coronary artery disease (CAD) – either three-vessel disease and/or left main disease – who also had heavy coronary artery calcification (CAC) had greater all-cause mortality 10 years after revascularization, compared with those without such lesions.

However, perhaps unexpectedly, patients with heavily calcified lesions (HCLs) had similar 10-year survival whether they had undergone coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI).

These findings from a post hoc analysis of the SYNTAX Extended Survival (SYNTAXES) study led by Hideyuki Kawashima, MD, PhD, National University of Ireland, Galway, and the University of Amsterdam, were published online Dec. 29, 2021, in JACC: Cardiovascular Interventions.

“There was an apparent lack of benefit at very long-term with CABG versus PCI in the presence of HCL,” Dr. Kawashima and corresponding author Patrick W. Serruys, MD, PhD, National University of Ireland and Imperial College London, summarized in a joint email to this news organization.

“Since HCLs – the final status of atherosclerosis and inflammation – reflect the aging process, complexity, and extensiveness of CAD, and comorbidity, it is possible that the currently available revascularization methods do not provide benefit in the prevention of long-term [10-year] mortality,” they suggested.

Health authorities in California, Texas, and Kansas have reported cases of “flurona,” in which people have seasonal flu and COVID-19 at the same time.

The first known case was detected in Israel, but until the first week of January no cases had been reported in the United States.

In Los Angeles, a teenaged boy tested positive for both illnesses at a COVID testing site in Brentwood, the Los Angeles Times reported. The child’s mother tested positive for COVID the next day.

“This is the first one that we’re aware of,” Steve Farzam, chief operating officer of 911 COVID Testing, told the LA Times. “In and of itself, it’s not overly concerning; however, it is concerning and can be problematic for someone who has pre-existing medical conditions, anyone who is immunocompromised.”

The teen and his family of five had just returned from vacation in Cabo San Lucas, Mexico. All said they tested negative before the trip, but they tested again when they got home because one of the children had a runny nose, Mr. Farzam said.

The boy, who had not been vaccinated for COVID or the flu, doesn’t have serious symptoms and is recovering at home.

In Houston, a 17-year-old boy, his siblings, and his father felt sick a few days before Christmas and went in for testing, TV station KTRK reported. The teen tested positive for both the flu and COVID.

“I ended up getting tested the day before Christmas for strep throat, flu and COVID,” the teenager, Alec Zierlein, told KTRK. “I didn’t think I had any of the three. It felt like a mild cold.”

Health officials reported Jan. 5 that a flurona case was detected in Hays, Kan., TV station WIBW reported. The patient was being treated in the ICU. No other details were provided. In Israel, flurona was first found in an unvaccinated pregnant woman at Rabin Medical Center in Petach Tikva, according to the Times of Israel. She tested positive for both viruses when she arrived at the medical center, and doctors double-checked to confirm her diagnosis. The woman had mild symptoms and was released in good condition, the news outlet reported.

Public health officials in Israel said they are concerned that an increase in both viruses at the same time could lead to many hospitalizations.

The record-setting surge in COVID-19 cases nationwide – including more than one million new infections reported on Jan. 3 – raises questions about whether the higher Omicron variant transmissibility will accelerate a transition from pandemic to endemic disease.

Furthermore, does the steep increase in number of people testing positive for SARS-CoV-2 mean the United States could finally be achieving a meaningful level of “herd immunity”?

Infectious disease experts weigh in on these possibilities.
 

An endemic eventuality?

Whether the current surge will mean the predicted switch to endemic COVID-19 will come sooner “is very hard to predict,” Michael Lin, MD, MPH, told this news organization.

“It’s an open question,” he said, “if another highly transmissible variant will emerge.”

On a positive note, “at this point many more people have received their vaccinations or been infected. And over time, repeated infections have led to milder symptoms,” added Dr. Lin, hospital epidemiologist at Rush Medical College, Chicago.

“It could end up being a seasonal variant,” he said.

COVID-19 going endemic is “a real possibility, but unfortunately ... it doesn’t seem necessarily that we’re going to have the same predictable pattern we have with the flu,” said Eleftherios Mylonakis, MD, PhD, chief of infectious diseases for Lifespan and its affiliates at Rhode Island Hospital and Miriam Hospital in Providence.

“We have a number of other viruses that don’t follow the same annual pattern,” he said.  

Unknowns include how long individuals’ immune responses, including T-cell defenses, will last going forward.

A transition from pandemic to endemic is “not a light switch, and there are no metrics associated with what endemic means for COVID-19,” said Syra Madad, DHSc., MSc, MCP, an infectious disease epidemiologist at Harvard’s Belfer Center for Science and International Affairs, Boston.

“Instead, we should continue to focus on decreasing transmission rates and preventing our hospitals from getting overwhelmed,” she said.
 

A hastening to herd immunity?

“The short answer is yes,” Dr. Lin said when asked if the increased transmissibility and increased cases linked to the Omicron surge could get the U.S. closer to herd immunity.

“The twist in this whole story,” he said, “is the virus mutated enough to escape first-line immune defenses, specifically antibodies. That is why we are seeing breakthrough infections, even in highly vaccinated populations.”

Dr. Mylonakis was more skeptical regarding herd immunity.

“The concept of herd immunity with a rapidly evolving virus is very difficult” to address, he said.

One reason is the number of unknown factors, Dr. Mylonakis said. He predicted a clearer picture will emerge after the Omicrons surge subsides. Also, with so many people infected by the Omicron variant, immune protection should peak.

“People will have boosted immunity. Not everybody, unfortunately, because there are people who cannot really mount [a full immune response] because of age, because of immunosuppression, etc.,” said Dr. Mylonakis, who is also professor of infectious diseases at Brown University.

“But the majority of the population will be exposed and will mount some degree of immunity.”

Dr. Madad agreed. “The omicron variant will add much more immunity into our population by both the preferred pathway – which is through vaccination – as well as through those that are unvaccinated and get infected with omicron,” she said.

“The pathway to gain immunity from vaccination is the safest option, and already over 1 million doses of the COVID-19 vaccine are going into arms per day – this includes first, second, and additional doses like boosters,” added Dr. Madad, who is also senior director of the System-wide Special Pathogens Program at New York City Health and Hospitals.
 

A shorter, more intense surge?

The United Kingdom’s experience with COVID-19 has often served as a bellwether of what is likely to happen in the U.S. If that is the case with the Omicron surge, the peak should last about 4 weeks, Dr. Mylonakis said.

In other words, the accelerated spread of Omicron could mean this surge passes more quickly than Delta.

Furthermore, some evidence suggests neutralizing antibodies produced by Omicron infection remain effective against the Delta variant – thereby reducing the risk of Delta reinfections over time.

The ability to neutralize the Delta variant increased more than fourfold after a median 14 days, according to data from a preprint study posted Dec. 27 on MedRxiv.

At the same time, neutralization of the Omicron variant increased 14-fold as participants mounted an antibody response. The study was conducted in vaccinated and unvaccinated people infected by Omicron in South Africa shortly after symptoms started. It has yet to be peer reviewed.

Eric Topol, MD, editor-in-chief of Medscape, described the results as “especially good news” in a tweet.

The current surge could also mean enhanced protection in the future.

“As we look at getting to the other side of this Omicron wave, we will end up with more immunity,” Dr. Madad said. “And with more immunity means we’ll be better guarded against the next emerging variant.”

“People will have boosted immunity. Not everybody, unfortunately, because there are people who cannot really mount [a full immune response] because of age, because of immunosuppression, etc.,” said Dr. Mylonakis, who is also professor of infectious diseases at Brown University.

“But the majority of the population will be exposed and will mount some degree of immunity.”

Dr. Madad agreed. “The omicron variant will add much more immunity into our population by both the preferred pathway – which is through vaccination – as well as through those that are unvaccinated and get infected with omicron,” she said.

“The pathway to gain immunity from vaccination is the safest option, and already over 1 million doses of the COVID-19 vaccine are going into arms per day – this includes first, second, and additional doses like boosters,” added Dr. Madad, who is also senior director of the System-wide Special Pathogens Program at New York City Health and Hospitals.
 

A shorter, more intense surge?

The United Kingdom’s experience with COVID-19 has often served as a bellwether of what is likely to happen in the U.S. If that is the case with the Omicron surge, the peak should last about 4 weeks, Dr. Mylonakis said.

In other words, the accelerated spread of Omicron could mean this surge passes more quickly than Delta.

Furthermore, some evidence suggests neutralizing antibodies produced by Omicron infection remain effective against the Delta variant – thereby reducing the risk of Delta reinfections over time.

The ability to neutralize the Delta variant increased more than fourfold after a median 14 days, according to data from a preprint study posted Dec. 27 on MedRxiv.

At the same time, neutralization of the Omicron variant increased 14-fold as participants mounted an antibody response. The study was conducted in vaccinated and unvaccinated people infected by Omicron in South Africa shortly after symptoms started. It has yet to be peer reviewed.

Eric Topol, MD, editor-in-chief of Medscape, described the results as “especially good news” in a tweet.

The current surge could also mean enhanced protection in the future.

“As we look at getting to the other side of this Omicron wave, we will end up with more immunity,” Dr. Madad said. “And with more immunity means we’ll be better guarded against the next emerging variant.”

The record-setting surge in COVID-19 cases nationwide – including more than one million new infections reported on Jan. 3 – raises questions about whether the higher Omicron variant transmissibility will accelerate a transition from pandemic to endemic disease.

Furthermore, does the steep increase in number of people testing positive for SARS-CoV-2 mean the United States could finally be achieving a meaningful level of “herd immunity”?

Infectious disease experts weigh in on these possibilities.
 

An endemic eventuality?

Whether the current surge will mean the predicted switch to endemic COVID-19 will come sooner “is very hard to predict,” Michael Lin, MD, MPH, told this news organization.

“It’s an open question,” he said, “if another highly transmissible variant will emerge.”

On a positive note, “at this point many more people have received their vaccinations or been infected. And over time, repeated infections have led to milder symptoms,” added Dr. Lin, hospital epidemiologist at Rush Medical College, Chicago.

“It could end up being a seasonal variant,” he said.

COVID-19 going endemic is “a real possibility, but unfortunately ... it doesn’t seem necessarily that we’re going to have the same predictable pattern we have with the flu,” said Eleftherios Mylonakis, MD, PhD, chief of infectious diseases for Lifespan and its affiliates at Rhode Island Hospital and Miriam Hospital in Providence.

“We have a number of other viruses that don’t follow the same annual pattern,” he said.  

Unknowns include how long individuals’ immune responses, including T-cell defenses, will last going forward.

A transition from pandemic to endemic is “not a light switch, and there are no metrics associated with what endemic means for COVID-19,” said Syra Madad, DHSc., MSc, MCP, an infectious disease epidemiologist at Harvard’s Belfer Center for Science and International Affairs, Boston.

“Instead, we should continue to focus on decreasing transmission rates and preventing our hospitals from getting overwhelmed,” she said.
 

A hastening to herd immunity?

“The short answer is yes,” Dr. Lin said when asked if the increased transmissibility and increased cases linked to the Omicron surge could get the U.S. closer to herd immunity.

“The twist in this whole story,” he said, “is the virus mutated enough to escape first-line immune defenses, specifically antibodies. That is why we are seeing breakthrough infections, even in highly vaccinated populations.”

Dr. Mylonakis was more skeptical regarding herd immunity.

“The concept of herd immunity with a rapidly evolving virus is very difficult” to address, he said.

One reason is the number of unknown factors, Dr. Mylonakis said. He predicted a clearer picture will emerge after the Omicrons surge subsides. Also, with so many people infected by the Omicron variant, immune protection should peak.

Hospitals across the United States are beginning to fill up with COVID-19 patients again, but a smaller proportion of cases are severe enough to move to intensive care or require mechanical ventilation.

So far, hospitalizations caused by the Omicron variant appear to be milder than in previous waves.

“We are seeing an increase in the number of hospitalizations,” Rahul Sharma, MD, emergency physician-in-chief for New York–Presbyterian/Weill Cornell Medicine, told the New York Times.

“We’re not sending as many patients to the ICU, we’re not intubating as many patients, and actually, most of our patients that are coming to the emergency department that do test positive are actually being discharged,” he said.

Most Omicron patients in ICUs are unvaccinated or have severely compromised immune systems, doctors told the newspaper.

Currently, about 113,000 COVID-19 patients are hospitalized across the country, according to the latest data from the Department of Health & Human Services. About 76% of inpatient beds are in use nationwide, with about 16% of inpatient beds in use for COVID-19.

Early data suggests that the Omicron variant may cause less severe disease. But it’s easier to catch the variant, so more people are getting the virus, including people who have some immunity through prior infection or vaccination, which is driving up hospitalization numbers.

In New York, for instance, COVID-19 hospitalizations have surpassed the peak of last winter’s surge, the newspaper reported. In addition, Maryland Gov. Larry Hogan declared a state of emergency on Jan. 4, noting that the state had more hospitalized COVID-19 patients than at any other time during the pandemic.

“We’re in truly crushed mode,” Gabe Kelen, MD, chair of the department of emergency medicine for the Johns Hopkins University, Baltimore, told the Times.

Earlier in the pandemic, hospitals faced challenges with stockpiling ventilators and personal protective equipment, doctors told the newspaper. Now they’re dealing with limits on hospital beds and staffing as health care workers test positive. The increase in COVID-19 cases has also come along with a rise in hospitalizations for other conditions such as heart attacks and strokes.

In response, some hospitals are considering cutting elective surgeries because of staff shortages and limited bed capacity, the newspaper reported. In the meantime, hospital staff and administrators are watching case numbers to see how high hospitalizations may soar because of the Omicron variant.

“How high will it go? Can’t tell you. Don’t know,” James Musser, MD, chair of pathology and genomic medicine at Houston Methodist, told the Times. “We’re all watching it, obviously, very, very closely.”

A CDC advisory panel recommended on Jan. 5 that 12- to 17-year-olds in the U.S. should get the Pfizer COVID-19 booster shot 5 months after a primary series of vaccinations.

The CDC had already said 16- and 17-year-olds “may” receive a Pfizer booster but the new recommendation adds the 12- to 15-year-old group and strengthens the “may” to “should” for 16- and 17-year-olds.

The committee voted 13-1 to recommend the booster for ages 12-17. CDC Director Rochelle Walensky, MD, must still approve the recommendation for it to take effect.

The vote comes after the FDA on Jan. 3 authorized the Pfizer vaccine booster dose for 12- to 15-year-olds.

The FDA action updated the authorization for the Pfizer vaccine, and the agency also shortened the recommended time between a second dose and the booster to 5 months or more (from 6 months). A third primary series dose is also now authorized for certain immunocompromised children between 5 and 11 years old. Full details are available in an FDA news release.

The CDC on Jan. 4 also backed the shortened time frame and a third primary series dose for some immunocompromised children 5-11 years old. But the CDC delayed a decision on a booster for 12- to 15-year-olds until it heard from its Advisory Committee on Immunization Practices on Jan. 5.

The decision came as school districts nationwide are wrestling with decisions of whether to keep schools open or revert to a virtual format as cases surge, and as pediatric COVID-19 cases and hospitalizations reach new highs.

The only dissenting vote came from Helen Keipp Talbot, MD, associate professor of medicine at Vanderbilt University in Nashville, Tenn.

She said after the vote, “I am just fine with kids getting a booster. This is not me against all boosters. I just really want the U.S. to move forward with all kids.”

Dr. Talbot said earlier in the comment period, “If we divert our public health from the unvaccinated to the vaccinated, we are not going to make a big impact. Boosters are incredibly important but they won’t solve this problem of the crowded hospitals.”

She said vaccinating the unvaccinated must be the priority.

“If you are a parent out there who has not yet vaccinated your child because you have questions, please, please talk to a health care provider,” she said.

Among the 13 supporters of the recommendation was Oliver Brooks, MD, chief medical officer of Watts HealthCare Corporation in Los Angeles.

Dr. Brooks said extending the population for boosters is another tool in the toolbox.

“If it’s a hammer, we should hit that nail hard,” he said.

Sara Oliver, MD, ACIP’s lead for the COVID-19 work group, presented the case behind the recommendation.

She noted the soaring Omicron cases.

“As of Jan. 3, the 7-day average had reached an all-time high of nearly 500,000 cases,” Dr. Oliver noted.

Since this summer, she said, adolescents have had a higher rate of incidence than that of adults.

“The majority of COVID cases continue to occur among the unvaccinated,” she said, “with unvaccinated 12- to 17-year-olds having a 7-times-higher risk of testing positive for SARS-CoV-2 compared to vaccinated 12- to 17-year-olds. Unvaccinated 12- to 17-year-olds have around 11 times higher risk of hospitalization than vaccinated 12- to 17-year-olds.

“Vaccine effectiveness in adolescents 12-15 years old remains high,” Dr. Oliver said, but evidence shows there may be “some waning over time.”

Discussion of risk centered on myocarditis.

Dr. Oliver said myocarditis rates reported after the Pfizer vaccine in Israel across all populations as of Dec. 15 show that “the rates of myocarditis after a third dose are lower than what is seen after the second dose.”

If a fish can drive …

Have you ever seen a sparrow swim? Have you ever seen an elephant fly? How about a goldfish driving a car? Well, one of these is not just something out of a children’s book.

In a recent study, investigators from Ben-Gurion University did the impossible and got a fish to drive a robotic car on land. How?

PxHere

No, there wasn’t a tiny steering wheel inside the tank. The researchers created a tank with video recognition ability to sync with the fish. This video shows that the car, on which the tank sat, would navigate in the direction that the fish swam. The goal was to get the fish to “drive” toward a visual target, and with a little training the fish was successful regardless of start point, the researchers explained.

So what does that tell us about the brain and behavior? Shachar Givon, who was part of the research team, said the “study hints that navigational ability is universal rather than specific to the environment.”

The study’s domain transfer methodology (putting one species in the environment of another and have them cope with an unfamiliar task) shows that other animals also have the cognitive ability to transfer skills from one terrestrial environment to another.

That leads us to lesson two. Goldfish are much smarter than we think. So please don’t tap on the glass.
 

We prefer ‘It’s not writing a funny LOTME article’!

So many medical journals spend all their time grappling with such silly dilemmas as curing cancer or beating COVID-19. Boring! Fortunately, the BMJ dares to stand above the rest by dedicating its Christmas issue to answering the real issues in medicine. And what was the biggest question? Which is the more accurate idiom: “It’s not rocket science,” or “It’s not brain surgery”?

Tumisu/Pixabay

English researchers collected data from 329 aerospace engineers and 72 neurosurgeons who took the Great British Intelligence Test and compared the results against 18,000 people in the general public.

The engineers and neurosurgeons were basically identical in four of the six domains, but neurosurgeons had the advantage when it came to semantic problem solving and engineers had an edge at mental manipulation and attention. The aerospace engineers were identical to the public in all domains, but neurosurgeons held an advantage in problem-solving speed and a disadvantage in memory recall speed.

The researchers noted that exposure to Latin and Greek etymologies during their education gave neurosurgeons the advantage in semantic problem solving, while the aerospace engineers’ advantage in mental manipulation stems from skills taught during engineering training.

But is there a definitive answer to the question? If you’ve got an easy task in front of you, which is more accurate to say: “It’s not rocket science” or “It’s not brain surgery”? Can we get a drum roll?

It’s not brain surgery! At least, as long as the task doesn’t involve rapid problem solving. The investigators hedged further by saying that “It’s a walk in the park” is probably more accurate. Plus, “other specialties might deserve to be on that pedestal, and future work should aim to determine the most deserving profession,” they wrote. Well, at least we’ve got something to look forward to in BMJ’s next Christmas issue.
 

For COVID-19, a syringe is the sheep of things to come

The logical approach to fighting COVID-19 hasn’t really worked with a lot of people, so how about something more emotional?

ChiemSeherin/Pixabay

People love animals, so they might be a good way to promote the use of vaccines and masks. Puppies are awfully cute, and so are koalas and pandas. And who can say no to a sea otter?

Well, forget it. Instead, we’ve got elephants … and sheep … and goats. Oh my.

First, elephant Santas. The Jirasartwitthaya school in Ayutthaya, Thailand, was recently visited by five elephants in Santa Claus costumes who handed out hand sanitizer and face masks to the students, Reuters said.

“I’m so glad that I got a balloon from the elephant. My heart is pounding very fast,” student Biuon Greham said. And balloons. The elephants handed out sanitizer and masks and balloons. There’s a sentence we never thought we’d write.

And those sheep and goats we mentioned? That was a different party.

Hanspeter Etzold, who “works with shepherds, companies, and animals to run team-building events in the northern German town of Schneverdingen,” according to Reuters, had an idea to promote the use of the COVID-19 vaccine. And yes, it involved sheep and goats.

Mr. Etzold worked with shepherd Wiebke Schmidt-Kochan, who arranged her 700 goats and sheep into the shape of a 100-meter-long syringe using bits of bread laying on the ground. “Sheep are such likable animals – maybe they can get the message over better,” Mr. Etzold told AP.

If those are the carrots in an animals-as-carrots-and-sticks approach, then maybe this golf-club-chomping crab could be the stick. We’re certainly not going to argue with it.
 

To be or not to be … seen

Increased Zoom meetings have been another side effect of the COVID-19 pandemic as more and more people have been working and learning from home.

The researchers noted that exposure to Latin and Greek etymologies during their education gave neurosurgeons the advantage in semantic problem solving, while the aerospace engineers’ advantage in mental manipulation stems from skills taught during engineering training.

But is there a definitive answer to the question? If you’ve got an easy task in front of you, which is more accurate to say: “It’s not rocket science” or “It’s not brain surgery”? Can we get a drum roll?

It’s not brain surgery! At least, as long as the task doesn’t involve rapid problem solving. The investigators hedged further by saying that “It’s a walk in the park” is probably more accurate. Plus, “other specialties might deserve to be on that pedestal, and future work should aim to determine the most deserving profession,” they wrote. Well, at least we’ve got something to look forward to in BMJ’s next Christmas issue.
 

For COVID-19, a syringe is the sheep of things to come

The logical approach to fighting COVID-19 hasn’t really worked with a lot of people, so how about something more emotional?

People love animals, so they might be a good way to promote the use of vaccines and masks. Puppies are awfully cute, and so are koalas and pandas. And who can say no to a sea otter?

Well, forget it. Instead, we’ve got elephants … and sheep … and goats. Oh my.

First, elephant Santas. The Jirasartwitthaya school in Ayutthaya, Thailand, was recently visited by five elephants in Santa Claus costumes who handed out hand sanitizer and face masks to the students, Reuters said.

“I’m so glad that I got a balloon from the elephant. My heart is pounding very fast,” student Biuon Greham said. And balloons. The elephants handed out sanitizer and masks and balloons. There’s a sentence we never thought we’d write.

And those sheep and goats we mentioned? That was a different party.

Hanspeter Etzold, who “works with shepherds, companies, and animals to run team-building events in the northern German town of Schneverdingen,” according to Reuters, had an idea to promote the use of the COVID-19 vaccine. And yes, it involved sheep and goats.

Mr. Etzold worked with shepherd Wiebke Schmidt-Kochan, who arranged her 700 goats and sheep into the shape of a 100-meter-long syringe using bits of bread laying on the ground. “Sheep are such likable animals – maybe they can get the message over better,” Mr. Etzold told AP.

If those are the carrots in an animals-as-carrots-and-sticks approach, then maybe this golf-club-chomping crab could be the stick. We’re certainly not going to argue with it.
 

To be or not to be … seen

Increased Zoom meetings have been another side effect of the COVID-19 pandemic as more and more people have been working and learning from home.

If a fish can drive …

Have you ever seen a sparrow swim? Have you ever seen an elephant fly? How about a goldfish driving a car? Well, one of these is not just something out of a children’s book.

In a recent study, investigators from Ben-Gurion University did the impossible and got a fish to drive a robotic car on land. How?

PxHere

No, there wasn’t a tiny steering wheel inside the tank. The researchers created a tank with video recognition ability to sync with the fish. This video shows that the car, on which the tank sat, would navigate in the direction that the fish swam. The goal was to get the fish to “drive” toward a visual target, and with a little training the fish was successful regardless of start point, the researchers explained.

So what does that tell us about the brain and behavior? Shachar Givon, who was part of the research team, said the “study hints that navigational ability is universal rather than specific to the environment.”

The study’s domain transfer methodology (putting one species in the environment of another and have them cope with an unfamiliar task) shows that other animals also have the cognitive ability to transfer skills from one terrestrial environment to another.

That leads us to lesson two. Goldfish are much smarter than we think. So please don’t tap on the glass.
 

We prefer ‘It’s not writing a funny LOTME article’!

So many medical journals spend all their time grappling with such silly dilemmas as curing cancer or beating COVID-19. Boring! Fortunately, the BMJ dares to stand above the rest by dedicating its Christmas issue to answering the real issues in medicine. And what was the biggest question? Which is the more accurate idiom: “It’s not rocket science,” or “It’s not brain surgery”?

Tumisu/Pixabay

English researchers collected data from 329 aerospace engineers and 72 neurosurgeons who took the Great British Intelligence Test and compared the results against 18,000 people in the general public.

The engineers and neurosurgeons were basically identical in four of the six domains, but neurosurgeons had the advantage when it came to semantic problem solving and engineers had an edge at mental manipulation and attention. The aerospace engineers were identical to the public in all domains, but neurosurgeons held an advantage in problem-solving speed and a disadvantage in memory recall speed.

The volume of prescription opioids dispensed at retail pharmacies in the United States dropped by 21% in recent years amid efforts to reduce unnecessary use of the painkillers, but the rate of decline varied greatly among types of patients and by type of clinician, a study found.

In a brief report published by Annals of Internal Medicine, researchers from the nonprofit RAND Corp reported an analysis of opioid prescriptions from two periods, 2008-2009 and 2017-2018.

The researchers sought to assess total opioid use rather than simply track the number of pills dispensed. So they used days’ supply and total daily dose to calculate per capita morphine milligram equivalents (MME) for opioid prescriptions, write Bradley D. Stein, MD, PhD, MPH, the study’s lead author and a senior physician researcher at RAND Corp, and his coauthors in their paper.

For the study, the researchers used data from the consulting firm IQVIA, which they say covers about 90% of U.S. prescriptions. Total opioid volume per capita by prescriptions filled in retail pharmacies decreased from 951.4 MME in 2008-2009 to 749.3 MME in 2017-2018, Dr. Stein’s group found.

(In 2020, IQVIA separately said that prescription opioid use per adult in this country rose from an average of 16 pills, or 134 MMEs, in 1992 to a peak of about 55 pills a person, or 790 MMEs, in 2011. By 2019, opioid use per adult had declined to 29 pills and 366 MMEs per capita.)

The RAND report found substantial variation in opioid volume by type of insurance, including a 41.5% decline (636.5 MME to 372.6 MME) among people covered by commercial health plans. That exceeded the 27.7% drop seen for people enrolled in Medicaid (646.8 MME to 467.7 MME). The decline was smaller (17.5%; 2,780.2 MME to 2,294.2 MME) for those on Medicare, who as a group used the most opioids.

‘Almost functions as a Rorschach test’

The causes of the decline are easy to guess, although definitive conclusions are impossible, Dr. Stein told this news organization.

Significant work has been done in recent years to change attitudes about opioid prescriptions by physicians, researchers, and lawmakers. Aggressive promotion of prescription painkillers, particularly Purdue Pharma’s OxyContin, in the 1990s, is widely cited as the triggering event for the national opioid crisis.

In response, states created databases known as prescription drug monitoring programs. The Centers for Disease Control and Prevention in 2016 issued guidelines intended to curb unnecessary use of opioids. The guidelines noted that other medicines could treat chronic pain without raising the risk of addiction. The Choosing Wisely campaign, run by a foundation of the American Board of Internal Medicine, also offered recommendations about limiting use of opioids. And insurers have restricted access to opioids through the prior authorization process. As a result, researchers will make their own guesses at the causes of the decline in opioid prescriptions, based on their own experiences and research interests, Dr. Stein said.

“It almost functions as a Rorschach test,” he said.

Dr. Stein’s group also looked at trends among medical specialties. They found the largest reduction between 2008-2009 and 2017-2018 among emergency physicians (70.5% drop from 99,254.5 MME to 29,234.3 MME), psychiatrists (67.2% drop from 50,464.3 MME to 16,533.0 MME) and oncologists (59.5% drop from 51,731.2 MME to 20,941.4).

Among surgeons, the RAND researchers found a drop of 49.3% from 220,764.6 to 111,904.4. Among dentists, they found a drop of 41.3% from 22,345.3 to 13,126.1.

Among pain specialists, they found a drop of 15.4% from 1,020,808.4 MME to 863,140.7 MME.

Among adult primary care clinicians, Dr. Stein and his colleagues found a drop of 40% from 651,489.4 MME in 2008-2009 to 390,841.0 MME in 2017-2018.

However, one of the groups tracked in the study increased the volume of opioid prescriptions written: advanced practice providers, among whom scripts for the drugs rose 22.7%, from 112,873.9 MME to 138,459.3 MME.

Dr. Stein said he suspects that this gain reflects a change in the nature of the practice of primary care, with nurse practitioners and physician assistants taking more active roles in treatment of patients. Some of the reduction seen among primary care clinicians who treat adults may reflect a shift in which medical personnel in a practice write the opioid prescriptions.

Still, the trends in general seen by Dr. Stein and coauthors are encouraging, even if further study of these patterns is needed, he said.

“This is one of those papers that I think potentially raises as many questions as it provides answers for,” he said.

What’s missing

Maya Hambright, MD, a family medicine physician in New York’s Hudson Valley, who has been working mainly in addiction in response to the opioid overdose crisis, observed that the drop in total prescribed volume of prescription painkillers does not necessarily translate into a reduction in use of opioids

“No one is taking fewer opioids,” Dr. Hambright told this news organization. “I can say that comfortably. They are just getting them from other sources.”

CDC data support Dr. Hambright’s view.

An estimated 100,306 people in the United States died of a drug overdose in the 12 months that ended in April 2021, an increase of 28.5% from the 78,056 deaths during the same period the year before, according to the CDC.

Dr. Hambright said more physicians need to be involved in prescribing medication-assisted treatment (MAT).

The federal government has in the past year loosened restrictions on a requirement, known as an X waiver. Certain clinicians have been exempted from training requirements, as explained in the frequently asked questions page on the Substance Abuse and Mental Health Services Administration website.

SAMHSA says legislation is required to eliminate the waiver. As of Dec. 30, 2021, more than half of the members of the U.S. House of Representatives were listed as sponsors of the Mainstreaming Addiction Treatment (MAT) Act (HR 1384), which would end the need for X waivers. The bill has the backing of 187 Democrats and 43 Republicans.

At this time, too many physicians shy away from offering MAT, Dr. Hambright said.

“People are still scared of it,” she said. “People don’t want to deal with addicts.”

But Dr. Hambright said it’s well worth the initial time invested in having the needed conversations with patients about MAT.

“Afterwards, it’s so straightforward. People feel better. They’re healthier. It’s amazing,” she said. “You’re changing lives.”

The research was supported by grants from the National Institutes of Health. Dr. Stein and coauthors reported no relevant financial relationships.

The Centers for Disease Control and Prevention’s recently updated guidance on isolating and testing were tied to the public’s increased interest in testing, Director Rochelle Walenksy, MD, said during a White House briefing Jan. 5.

Health officials recently shortened the recommended COVID-19 isolation and quarantine period from 10 days to 5, creating confusion amid an outbreak of the highly transmissible Omicron variant, which now accounts for 95% of cases in the United States.

Then, in slightly updated guidance, the CDC recommended using an at-home antigen test after 5 days of isolation if possible, even though these tests having aren’t as sensitive to the Omicron variant, according to the FDA.

“After we released our recs early last week, it became very clear people were interested in using the rapid test, though not authorized for this purpose after the end of their isolation period,” Dr. Walensky said. “We then provided guidance on how they should be used.”

“If that test is negative, people really do need to understand they must continue to wear their mask for those 5 days,” Dr. Walensky said.

But for many, the CDC guidelines are murky and seem to always change.

“Nearly 2 years into this pandemic, with Omicron cases surging across the country, the American people should be able to count on the Centers for Disease Control and Prevention for timely, accurate, clear guidance to protect themselves, their loved ones, and their communities,” American Medical Association president Gerald Harmon, MD, said in a statement. “Instead, the new recommendations on quarantine and isolation are not only confusing, but are risking further spread of the virus.”

About 31% of people remain infectious 5 days after a positive COVID-19 test, Dr. Harmon said, quoting the CDC’s own rationale for changing its guidance.

“With hundreds of thousands of new cases daily and more than a million positive reported cases on January 3, tens of thousands – potentially hundreds of thousands of people – could return to work and school infectious if they follow the CDC’s new guidance on ending isolation after 5 days without a negative test,” he said. “Physicians are concerned that these recommendations put our patients at risk and could further overwhelm our health care system.”

Instead, Dr. Harmon said a negative test should be required for ending isolation.

“Reemerging without knowing one’s status unnecessarily risks further transmission of the virus,” he said.

Meanwhile, also during the White House briefing, officials said that early data continue to show that Omicron infections are less severe than those from other variants, but skyrocketing cases will still put a strain on the health care system.

“The big caveat is we should not be complacent,” presidential Chief Medical Adviser Anthony Fauci, MD, said a White House briefing Jan. 5.

He added that Omicron “could still stress our hospital system because a certain proportion of a large volume of cases, no matter what, are going to be severe.”

Cases continue to increase greatly. This week’s 7-day daily average of infections is 491,700 -- an increase of 98% over last week, Dr. Walensky said. Hospitalizations, while lagging behind case numbers, are still rising significantly: The daily average is 14,800 admissions, up 63% from last week. Daily deaths this week are 1,200, an increase of only 5%.

Dr. Walensky continues to encourage vaccinations, boosters, and other precautions.

“Vaccines and boosters are protecting people from the severe and tragic outcomes that can occur from COVID-19 infection,” she said. “Get vaccinated and get boosted if eligible, wear a mask, stay home when you’re sick, and take a test if you have symptoms or are looking for greater reassurance before you gather with others.”

The Centers for Disease Control and Prevention’s recently updated guidance on isolating and testing were tied to the public’s increased interest in testing, Director Rochelle Walenksy, MD, said during a White House briefing Jan. 5.

Health officials recently shortened the recommended COVID-19 isolation and quarantine period from 10 days to 5, creating confusion amid an outbreak of the highly transmissible Omicron variant, which now accounts for 95% of cases in the United States.

Then, in slightly updated guidance, the CDC recommended using an at-home antigen test after 5 days of isolation if possible, even though these tests having aren’t as sensitive to the Omicron variant, according to the FDA.

“After we released our recs early last week, it became very clear people were interested in using the rapid test, though not authorized for this purpose after the end of their isolation period,” Dr. Walensky said. “We then provided guidance on how they should be used.”

“If that test is negative, people really do need to understand they must continue to wear their mask for those 5 days,” Dr. Walensky said.

But for many, the CDC guidelines are murky and seem to always change.

“Nearly 2 years into this pandemic, with Omicron cases surging across the country, the American people should be able to count on the Centers for Disease Control and Prevention for timely, accurate, clear guidance to protect themselves, their loved ones, and their communities,” American Medical Association president Gerald Harmon, MD, said in a statement. “Instead, the new recommendations on quarantine and isolation are not only confusing, but are risking further spread of the virus.”

About 31% of people remain infectious 5 days after a positive COVID-19 test, Dr. Harmon said, quoting the CDC’s own rationale for changing its guidance.

“With hundreds of thousands of new cases daily and more than a million positive reported cases on January 3, tens of thousands – potentially hundreds of thousands of people – could return to work and school infectious if they follow the CDC’s new guidance on ending isolation after 5 days without a negative test,” he said. “Physicians are concerned that these recommendations put our patients at risk and could further overwhelm our health care system.”

Instead, Dr. Harmon said a negative test should be required for ending isolation.

“Reemerging without knowing one’s status unnecessarily risks further transmission of the virus,” he said.

Meanwhile, also during the White House briefing, officials said that early data continue to show that Omicron infections are less severe than those from other variants, but skyrocketing cases will still put a strain on the health care system.

“The big caveat is we should not be complacent,” presidential Chief Medical Adviser Anthony Fauci, MD, said a White House briefing Jan. 5.

He added that Omicron “could still stress our hospital system because a certain proportion of a large volume of cases, no matter what, are going to be severe.”

Cases continue to increase greatly. This week’s 7-day daily average of infections is 491,700 -- an increase of 98% over last week, Dr. Walensky said. Hospitalizations, while lagging behind case numbers, are still rising significantly: The daily average is 14,800 admissions, up 63% from last week. Daily deaths this week are 1,200, an increase of only 5%.
