In 2020, “the virus” has come to mean one thing: SARS-CoV-2. But just a few years ago, Zika had the world's attention, as one news report after another described children with microcephaly born to women who'd been infected while pregnant.

It can be difficult for physicians to determine whether a birth defect is the result of Zika. Most infections have few or no symptoms, and mothers may not know if they’ve been exposed. Karin Nielsen, MD, remembers one child in particular, a 9-month-old boy born with microcephaly whose parents brought the infant to her in 2018 because he had started having seizures.

The child was born in Mexico in 2017, when the Zika virus was still known to be circulating in the Americas, said Dr. Nielsen, a pediatric infectious disease specialist at the University of California, Los Angeles. Brain imaging revealed calcifications and other signs in the boy’s brain that were consistent with exposure. But his mother said she was never sick during pregnancy.

Because Zika is transmitted not just via mosquito and from mother to fetus but also sexually, Dr. Nielsen thinks the mother probably contracted an asymptomatic infection from her husband, who recalled having a rash when she was 4 months pregnant. When they participated in a research study, both parents tested positive for Zika antibodies.

“The child had the classic symptoms of congenital Zika syndrome,” Dr. Nielsen said. “He was 9 months old, he had microcephaly, and he was having mal seizures.”

Researchers have since learned that children with such classic symptoms represent only a small proportion of those affected by prenatal Zika exposure – about 3%-5%. The virus was at its height during the 2016-2016 epidemic and is not currently causing outbreaks. But as researchers have followed cohorts of children exposed to Zika in utero, they have found many subtler effects physicians will need to monitor as the children grow up.

“When we’re seeing hundreds of kids with microcephaly, we had a lot of people infected,” Dr. Nielsen said. “Microcephaly is only the tip of the iceberg.”

Early evidence

Microcephaly may be the most identifiable symptom of fetal Zika infection, but researchers tracking cohorts of exposed children have begun to build a more complete picture of what long-term effects might look like. “Congenital Zika syndrome” refers specifically to the most severe effects from prenatal exposure: microcephaly, seizures, cerebral palsy, hearing and vision problems, feeding difficulties, and other disabilities. But hundreds, if not thousands, of children have been exposed to Zika in the womb – it’s not clear how many, Dr. Nielsen said – and many show a range of effects that don’t officially qualify as congenital Zika syndrome.

Current estimates suggest about one third of exposed children have some type of neurologic or neurodevelopmental problem, even though prevalence of visible effects is much lower. Over time, the incidence of these effects has fluctuated; some developmental delays and sensory deficits began manifesting later in childhood whereas others, at least in a few children, have resolved.

“We’re just beginning to have some of the data that we need to think about the full spectrum of outcomes,” said Cindy Moore, MD, chief medical officer in the Division of Congenital and Developmental Disorders in the Centers for Disease Control and Prevention’s National Center on Birth Defects and Developmental Disabilities.

“As we’re learning more and more, we’re learning the spectrum is expanding to less severe forms,” Dr. Moore said. “We do know that with some infections, there are later onset of problems.”

Studies published in 2018 described cohorts of children whose mothers had confirmed or suspected Zika infections during pregnancy in the French Territories of America (Guadalupe, Martinique, and French Guiana) and in Salvador, Brazil. The research provided valuable early data on the incidence of microcephaly and other severe effects in newborns, but noted the need for long-term follow up.

The U.S. Zika Pregnancy and Infant Registry is one of the largest such cohorts. In August 2018, researchers made their first report on data from the registry They looked at 1450 children age 1 or older who had undergone neuroimaging or screenings (developmental, vision, hearing) or both. In 6%, at least one birth defect was linked to Zika, and 9% had at least one neurodevelopmental abnormality.

As these children age past developmental milestones, more effects will likely manifest – even in those children whose appearance and imaging presented as healthy at birth.

Longer-term follow up

Nielsen at UCLA and M. Elisabeth Lopes Moreira, MD, of the Oswaldo Cruz Foundation in Rio de Janeiro, are following a cohort of more than 100 children born in Rio de Janeiro during Brazil’s 2015-2016 epidemic to mothers with symptomatic, PCR-confirmed Zika infections during pregnancy. In December 2018, their team reported that rates of severe neurodevelopmental delay and sensory dysfunction – 14% of 131 children aged 12-18 months – were higher than those found in earlier studies.

In August 2019, the team described neurodevelopmental, vision, and hearing outcomes in 216 Zika-exposed children 2 years after birth. They used the Bayley-III Scales of Infant and Toddler Development to assess cognitive, language and motor skills in 146 of the children. Forty percent of them were below or very below average in development, more than one third (35%) had language delays, 12% percent had hearing loss, and 7% had abnormal eye anatomy, such as underdeveloped retinas.

In two of the eight children in the cohort with microcephaly, the abnormality unexpectedly resolved. Although that finding received a lot of press, Dr. Nielsen pointed out that “not all microcephalies are created equal.”

In one case, a child born small for gestational age had proportional microcephaly: the baby›s head circumference met the criteria for microcephaly, but the infant›s head was proportional to the body so, as the child grew, the apparent microcephaly disappeared.

In the other case, the child was born with craniosynostosis, in which the skull sutures fuse too early – another effect seen with prenatal Zika exposure, Dr. Nielsen said. After corrective surgery, the child’s head circumference no longer met the definition of microcephaly, but the child still had symptoms related to congenital Zika: a developmental delay and calcifications in the brain. Meanwhile, two other children in the Rio cohort developed secondary microcephaly.

In another follow-up study of children up to age 4, Dr. Nielsen and colleagues found that both clinicians and family may think that Zika-exposed infants without microcephaly are developing normally, but that may not be true. Nearly 70% of children without microcephaly had neurologic abnormalities on physical examination, and more than half had failure to thrive because of poor feeding related to neurologic abnormalities.

Initially, some children may be able to mask subtle problems. A study published in January from Sarah B. Mulkey, MD, PhD, of Children’s National Hospital in Washington, DC, and colleagues described neurodevelopmental outcomes in 70 Colombian children up to 18 months old who had been exposed to Zika in utero. The children had a normal head circumference at birth and a normal fetal MRI, but – compared with typically developing peers – their communication, social cognition, and mobility scores on standardized assessments tended to decline as they got older.

“Especially in a very young child, there’s always going to be a possibility that you can compensate for a deficit, and it appears that at least some of these children are doing so,” said William J. Muller, MD, PhD, associate professor of pediatrics at Northwestern University, Chicago. When the children are older, certain behavioral effects will become easier to assess.

“With these children now approaching school age, understanding the full spectrum of neurodevelopmental abnormalities has important public health and educational system implications,” Dr. Muller and Dr. Mulkey wrote in a commentary about one of Dr. Nielsen’s studies.

Researchers face multiple barriers to understanding the long-term effects of fetal Zika infection. Many infants known to have been exposed in utero never received the recommended early assessments and haven’t been followed long-term. Particularly in Brazil, poverty, poor access to healthcare, and overcrowding all complicate surveillance efforts, Dr. Muller said. Stigma related to children’s neurodevelopmental problems also can potentially reduce a mother’s willingness to attend all follow-ups and assessments.

Some children may have been exposed but were never recognized as such, making it difficult for researchers to track their development and assemble a complete picture of prenatal Zika infection outcomes. Asymptomatic infection occurs in about 80% of Zika infections, though it’s not clear if that number holds for infections during pregnancy as well, according to Dr. Muller and Dr. Mulkey. Because nearly all the current research involves children whose mothers had symptomatic infections, the studies’ generalizability may be limited.

Those likely asymptomatic infections are also a major reason none of the cohorts have comparison groups.

“There are literally hundreds of things that can contribute to or cause developmental problems,” said Dr. Moore of the CDC, who noted that it would be nice to have a comparison group so as to know what Zika may not be responsible for. That said, it would be difficult-to-impossible to create a control group with similar geographic and demographic characteristics as the exposed children, a group who researchers can be certain weren’t exposed.

Neurodevelopmental disabilities occur in about 15% of the general population, making it difficult to determine whether Zika causes any or all long-term, less severe developmental findings in exposed children. The difficulty only compounds with time: the older a child is when a developmental problem is recognized, the harder it is to go back and say the problem is a result of something that occurred before birth, Dr. Moore said. “It’s a challenging field to say, this is what caused that outcome.” 

Exposed children need continued evaluation

Interpreting the clinical implications of available studies is also challenging. It can be difficult to distinguish between central nervous system damage and peripheral damage, leaving the true etiology of poor vision or hearing elusive. The Zika virus can attack both the optic nerve and the part of the brain that interprets what a person sees: “Are you not seeing well because that part of your brain is not developed, or is it just a problem with the eye?” Dr. Nielsen said. 

When problems can’t be precisely identified, successful interventions are harder. If the cochlea is normal, for instance, but the part of the brain that interprets sound or language has deficits, a hearing aid won’t help.

The services and interventions that children need depend on their specific developmental or cognitive deficits, regardless of the cause. But if clinicians know the cause is likely Zika exposure, they also know to look for other deficits.

Children showing likely effects of congenital Zika infection should be further evaluated for other possible birth defects and referred to a developmental specialist, early intervention services, and family support services. Depending on the child, primary care providers might consider referrals to an infectious disease specialist, clinical geneticist, neurologist, or other specialists.

Even with no confirmed infection or visible signs at birth, clinicians should remain vigilant with children who had possible exposure. A recently published study of 120 children conceived during the Zika outbreak in Paraíba, Brazil, assessed as infants and then again at 2 years old, exemplifies why. Researchers identified adverse neurologic outcomes and developmental delays in several children who had no physical evidence of birth defects as newborns, but whose antibody tests showed possible infection.

“In this post-epidemic period, with decreased Zika transmission and less public awareness,” wrote Dr. Mulkey and a colleague, “follow-up of these children is now more important than ever”.

Metformin, oleander extract, azithromycin, famotidine, fluvoxamine, hydroxychloroquine, indomethacin, remdesivir, different vaccines, and many others. What does this disparate group of agents have in common? They’re all being bandied about as treatments for COVID-19.

This sort of thing makes big headlines in the news when someone even mentions them as a possible treatment, but so do proposed treatments for Alzheimer’s disease, various cancers, and other devastating illnesses. It triggers calls to doctors’ offices by patients wanting to be put on them, demands for them to be sold over the counter, and less-then-scrupulous people selling all kinds of things claiming to contain them and cure the disease for only $89.95 with free shipping if you act now.

Even in ordinary times (whatever that means anymore) it doesn’t take much for even a hint of success to make the news, spiking calls to doctors’ offices asking about “that new treatment I saw.” Of course, the number of drugs that are proven to be successful and come to market is a fraction of what’s actually tested.

Since the many failures don’t make headlines like successes do, the general public moves on and doesn’t even remember the initial story after a while. Only the medical and pharmaceutical professions are left to remember “we tried that, it didn’t work.”

We learn as much from failure as we do from success – sometimes more – but failure doesn’t make headlines or sell papers or get clicks.

The research scientists and physicians know this and how long it can take to find something that works. In some diseases it still hasn’t happened, in spite of billions spent and decades going by.

Unfortunately, nonscientific people (which is most of the population) just see our remarkable breakthroughs evidenced by shiny equipment and new drugs, and only read the headlines about successes. They don’t realize the many years and failures behind them.

In a world used to instant gratification, people want a cure for the coronavirus now. It doesn’t help to have nonmedical talking heads on the news egging this belief on. The few voices of reason are drowned out.

The polio virus was identified in 1908 (the disease is thousands of years old). The Salk vaccine came out in 1955. That’s a 47-year gap. I doubt it will take that long for COVID-19, but the point is that these things never have, and never will, happen overnight.

The problem isn’t science or medicine. It’s unreasonable expectations for immediate success. While science and diseases may change over time, human nature doesn’t.

Metformin, oleander extract, azithromycin, famotidine, fluvoxamine, hydroxychloroquine, indomethacin, remdesivir, different vaccines, and many others. What does this disparate group of agents have in common? They’re all being bandied about as treatments for COVID-19.

The US Food and Drug Administration has removed two senior public relations employees, one of whom advised the agency against unbridled promotion of convalescent blood plasma as a treatment for people with COVID-19, multiple media outlets reported Aug. 28.

Officials claim the dismissals are coincidental and are not related to a controversy about whether claims regarding convalescent plasma therapy that were put forth by President Donald Trump and FDA Commissioner Stephen M. Hahn, MD, were exaggerated, according to reports from The New York Times , CNN, and elsewhere.

One of the PR employees, Emily Miller, was on the job less than 2 weeks. The White House named her FDA chief spokeswoman 11 days ago, but Hahn removed her from that post Aug. 28.

On Aug. 27, the US Department of Health and Human Services terminated the contract for Wayne L. Pines, a PR consultant to the FDA. Pines reportedly advised Hahn to apologize for making misleading claims about the therapeutic benefits of convalescent plasma therapy for COVID-19.

The FDA did not respond to multiple requests for comment.

The controversy stems from comments Hahn made about the announcement of the emergency use authorization for convalescent plasma for patients with COVID-19. He said that plasma had been found to save the lives of 35 out of every 100 people who were treated. That statement was later found to be erroneous because he presented a relative risk reduction as an absolute decrease in risk. He later apologized via Twitter.

Researchers running clinical trials to evaluate the efficacy of convalescent plasma for COVID-19 are concerned that the emergency use authorization could thwart efforts to recruit participants for their studies.

New York City Health + Hospitals (NYCH+H), the country’s largest public health care system, encompasses 11 hospitals with 4,354 staffed acute beds during normal times. It serves as the safety net for 1.1 million of the 8.4 million residents of the most populous city in the United States, many of them uninsured, undocumented, covered by Medicaid, or otherwise disadvantaged.

At the very epicenter in the early days of the historic COVID-19 pandemic, NYCH+H transferred patients between its facilities, added medical and ICU beds by the hundreds, mobilized palliative care volunteers, harnessed telemedicine and a clinician hotline, and made other sweeping changes to ensure that the city’s public health system would be able to respond to demand at the peak of the surge. That peak hit in April, when an average of 9,000 new COVID-19 cases were being reported in the city every day.

Through it all, hospitalists have played critical roles in both planning for the system’s response and caring for severely ill COVID-19 patients. Their stories reflect both the unprecedented demands on the system and the dedication of frontline clinicians.

One of those, Carla Saladini-Aponte, MD, who just finished her residency in June 2019, found herself on the firing line in March 2020 as an attending physician at 457-bed NYCH+H/Jacobi Hospital in the Bronx. “I have experienced so much in my first year on the job, dealing with a disease that we’ve never seen before,” she said. “We didn’t grasp the extent of the COVID crisis in the beginning, so we were emotionally unprepared when it first hit.”

Starting on March 30, NYCH+H administration mobilized a centralized incident command structure to coordinate response systemwide to a rapidly changing situation.

Two weeks later Jacobi was a COVID-19 hospital, top to bottom, with its medical ICU beds increased from 12 to more than 100. By mid-April, Dr. Saladini-Aponte’s team, one of 11 medical teams in the hospital, had 26 patients, all of them with COVID-19. There was not a consensus in the early days on how to manage patients with severe respiratory distress. “But by the time the surge came, we had a better understanding of the scope of the situation,” she said.

Learning to be an attending

“They don’t teach you how to be an attending during residency,” Dr. Saladini-Aponte said. “At the beginning I wasn’t such a good teacher. I just wanted to prove myself and stay one step ahead of the residents. But as an academic hospitalist you have to listen to others. I learned to ask questions of the residents every morning, including how they were doing personally.”

Sometimes a visiting consultant would ask on the floor: “‘Where’s your attending?’” not recognizing Dr. Saladini-Aponte, fresh out of residency, filling that role. At times, she felt like a PGY-4 (postgraduate year 4). But she quickly grew into the attending role and was asked to be site coordinator for the mobilization of palliative medicine volunteers at Jacobi.

“We found ourselves having to make tough ethical decisions. Some patients, even if we provided a ventilator and maximum oxygen therapy, would still die. There were difficult discussions when we didn’t know if we had enough dialysis machines, or how to manage other limited resources. The hospital was saying: You decide, if there’s a high degree of certainty about the outcome. But we had never practiced medicine this way before,” she said.

“That’s why our hospital provided daily ethics meetings with our ethics council. There would be eight people sitting 6 feet apart in a conference room, all wearing masks. We’d talk about situations that were giving us trouble. Their role wasn’t to provide answers but to help us see the scope of the situation and the complexities,” she explained.

Dr. Saladini-Aponte said she has had many sleepless nights since the pandemic began. “Sometimes, I would come home from work and lie down on the floor and cry,” she said. “But we had so much support from volunteers helping our little hospitalist service of seven.” It was also important to keep up with the clinical information, and one of her coworkers created “cheat sheets” for the clinicians, regularly updated with the latest essential information on antibiotics, testing, and the like.

“At the peak, I was trying to read everything I could about the virus. I was just pulling myself in too many directions. I asked for help from my boyfriend to remind me not to log onto my computer when I came home from work,” she said. “One of my techniques for preventing burnout was just to avoid social media. I couldn’t deal with what was going on in the news. It just angered me. Even now, seeing people without masks makes me very uncomfortable.”
 

Organizing the crisis response

As chief value officer for NYCH+H, Hyung (Harry) Cho, MD, FACP, SFHM, typically focuses on issues of patient safety and overuse of medical treatments in the health system. But in the COVID-19 crisis, he found himself at the forefront of organizing its response. “We tried to provide support centrally and to standardize practice in how we test and treat,” he said.

“We were truly at the epicenter of the pandemic,” Dr. Cho said. “All of our hospitals had different experiences, and unique responses. But the system worked well.” Patients were transferred from the more overtaxed hospitals to Bellevue and other NYCH+H hospitals with spare beds. An emergency medical response structure was put in place, and every morning the system’s Tiger Team, with multidisciplinary personnel from administration, operations, logistics, and medical/technical specialists, would gather virtually to discuss needs across the system.

“It was a very open atmosphere and we asked people to report what was happening on the ground,” Dr. Cho said. “We started rapidly reviewing batches of 20 patients at a time for transfer in order to alleviate pressure in the most overtaxed ERs.”

NYCH+H also had to work through concerns about PPE, just like other U.S. hospitals. Treatment guidelines were changing by the day. Medical concerns were relayed at a rapid pace. Another priority was trying to limit unnecessary exposure for staff through a recommendation that only one clinician from a team would go into the room of an infected patient, unless another was absolutely needed.

The reality of public health

NYCH+H was created by the New York State Legislature in 1969 and rebranded in 2015. It includes a low- to no-cost health insurance plan called MetroPlus, along with outpatient centers, comprehensive case management, and social supports in the home.

“What people know about public health systems is that we typically are underresourced. That’s just the reality of public health,” Dr. Cho said. “We help the community, the underserved. The people who truly needed our help are also the ones who have been disproportionately affected by COVID-19. And that is where we really shine as a system.”

Dr. Cho lauded the performance of the health system’s frontline staff. “Watching them come together during the entire pandemic, and do their best every day, was truly inspiring,” he said. “But when they got to the peak, it really took an emotional toll on them.”

NYCH+H’s in-house staff support program, called Helping Healers Heal, was mobilized with specially trained teams at each of its 11 hospitals to provide peer-to-peer support, mental health expertise, and team-debriefing sessions to staff members following traumatic events. Support is provided both over the phone and in person on the floors, Dr. Cho said. “During the surge, everything was happening so quickly, there was no time to take a pause. Now, as we are able to catch our breath, that’s when they most need support.”

The hospitalists at NYCH+H hospitals intended to have goals-of-care conversations with all patients, but everyone was very busy – so having these conversations became harder and harder, Dr. Cho said. Recognizing limited staffing for the quadrupling of patients who needed palliative care at NYCH+H hospitals, he asked the medicine chairs about their palliative care needs and then used social media outreach to ask for help. The message went viral, attracting 413 volunteers from across the country. Sixty-seven telepalliative volunteers were put to work doing goals-of-care conversations remotely with inpatients and their families.¹

Expediting transfers

For Ian Fagan, MD, a hospitalist and associate medical director for general internal medicine Inpatient Services at Bellevue Hospital in Manhattan, hospitalist shifts are a normal part of his job. But he had to give them up during the surge to focus on planning, management, and especially scheduling other doctors, with sufficient backups needed to cover last minute changes. Dr. Fagan did that by using the existing pool of hospitalist staff, physicians who were reassigned from other specialties, agency staff, military medical personnel, and volunteer doctors who flew in from around the country to help. He also worked 10- to 12-hour days for 36 consecutive days.

The impact of disparities in access to care in New York City was reflected in the greater demand for care in the hospitals in Brooklyn, Queens, and the Bronx. “With fewer patients and more hospital beds in Manhattan, we had the capacity to share our beds,” Dr. Fagan said. “It was so amazing to me how quickly we could move patients from one hospital to another. We started accepting up to 40 transfers a day. But hey, we were still really busy.”

Bellevue is the nation’s oldest public hospital. “We care for the homeless, for immigrants, and we don’t ask questions. That’s our mission. I’m so proud to work here, and so grateful,” Dr. Fagan said. “If someone is undocumented or without insurance, I will give them exactly the same care. We stepped up in a big way to care for people of New York, but we’ve always been there for them – and we were there for them during the COVID surge.”

The hospitals in the system also worked together in ways Dr. Fagan had never seen. “It helped to have a central command structure with a bird’s eye view from above the level of individual hospitals, to organize and see which hospitals could step up. It’s good to have the data to put it in perspective,” he said. The system also utilized a temporary low-acuity medical center set up by NYCH+H on Roosevelt Island, as well as field hospitals organized at the Jacob K. Javits Convention Center and the USTA Billie Jean King National Tennis Center.

“At Bellevue we tried to stay ready, with the ability to turn former hospital units that were being used as offices back to beds. We always had three units lined up that were fully ready to convert. For example, I was medical director of the preop clinic and one day they gave us 24 hours to pack everything and move out. Three days later, it was a 24-bed unit. We also built a more robust rapid response and code team,” he said.

“It was hard for me not to take hospitalist shifts, because my identity is being a doctor. I eventually came to terms with the importance of the role that I was doing every day. I felt I could protect my colleagues, and if they were having an emotional day, to give them the opportunity to talk to someone. I also did the onboarding, one-on-one, of the new doctors.”

As the crisis in New York City has ebbed, Dr. Fagan was recently able to again take a week of clinical service. “The first day back on the floor I felt that I had forgotten everything. But by the end of the day, I thought, ‘Okay, I do know how to do this, after all.’ Census is down here. It’s quiet. That’s good. We need it now,” he said.

“I think the hardest moment for me was when the head nurse on our trauma unit, Ernesto DeLeon, known to everybody here, died of COVID in our ICU in April,” Dr. Fagan said. When Mr. DeLeon died, 100 hospital personnel gathered in the halls outside the room to pay their respects. “There had been a palpable fear in our lives – and this showed us that the fear was real. Ernesto was the first person I knew well who died, who acquired COVID at work doing what we’re all doing. We haven’t lost any doctors yet, but when this nurse died, we allowed ourselves to realize that this is personal. In that moment, we needed to allow ourselves to be human.”

Joan Curcio, MD, associate director of medicine at Elmhurst Hospital, said Elmhurst was where the story started for New York City and for NYCH+H. “I trained here and have spent my entire career at this hospital. It came to feel like what a battleground must be like, with things coming at you from every direction,” she said. “It was overwhelming in ways I could not have foreseen. I had seen videos from Italy [an early COVID-19 epicenter], but until it happened here, it was just hard to process.”

Things started slowly, with a few patients with severe acute respiratory distress syndrome and a 5- to 7-day turnaround to get results of their viral infection tests. “By week 2, a greater number of patients from our clinics and testing sites were filtering through the emergency department. Then hundreds.”

The normal occupancy rate for the department of medicine at Elmhurst is 110-115%, which typically means full beds plus patients in the emergency department. “We started to grow to 160, then 180, and then a peak of 250% of occupancy. We took over a rehab surgery floor, then a 35-bed surgery and hospice floor, which went to full capacity just like that,” she said. The number of non–critical care service teams increased to 20, working with redeployed staff, volunteers, military, and agency personnel, while ICU beds increased from 20 to 105.

“We were dealing with a much higher acuity level and enduring emotional turmoil with families, trying to carve out time to call them after our shift was over,” Dr. Curcio explained. Elmhurst developed a call-in hotline and a daily call-out service for families. Technology was mobilized to provide video visits and new systems were designed for isolation and for PPE distribution and use.

“I just felt that I couldn’t get everything done. I felt continually overwhelmed, and it didn’t matter how much time I took. I never felt I was able to give enough to anybody in any area, which was hard to take,” Dr. Curcio said. “But I still felt a sense of purpose and that I was making a difference – thanks to lots of support from the central office.”

Patient volume at Elmhurst is now down, lower than Dr. Curcio has ever seen it. “One of the main issues right now, moving forward, is ‘how do we function in a post-crisis mode?’” she said. The process of transitioning back to non-COVID-19 care will be complex. “When we clear a floor and clean it to go back to being a cold [COVID-19-negative] unit, it’s a whole different level of cleaning that takes 7 days.”

One moment that was particularly jarring for Dr. Curcio occurred while she was giving a tour of the hospital to visiting military medical personnel. “We went into the emergency department and I turned around and looked into a shower room, which was full of body bags. They were all full.”

But the experience has also been inspiring. “People gave their all without complaint. We hospitalists, and all those recruited to act as hospitalists, essentially took responsibility for the COVID response,” she said. “This was, hopefully, the experience of a lifetime as a medical professional. I wouldn’t want to ever experience something as daunting as this again.”

NYCH+H’s in-house staff support program, called Helping Healers Heal, was mobilized with specially trained teams at each of its 11 hospitals to provide peer-to-peer support, mental health expertise, and team-debriefing sessions to staff members following traumatic events. Support is provided both over the phone and in person on the floors, Dr. Cho said. “During the surge, everything was happening so quickly, there was no time to take a pause. Now, as we are able to catch our breath, that’s when they most need support.”

The hospitalists at NYCH+H hospitals intended to have goals-of-care conversations with all patients, but everyone was very busy – so having these conversations became harder and harder, Dr. Cho said. Recognizing limited staffing for the quadrupling of patients who needed palliative care at NYCH+H hospitals, he asked the medicine chairs about their palliative care needs and then used social media outreach to ask for help. The message went viral, attracting 413 volunteers from across the country. Sixty-seven telepalliative volunteers were put to work doing goals-of-care conversations remotely with inpatients and their families.¹

Expediting transfers

For Ian Fagan, MD, a hospitalist and associate medical director for general internal medicine Inpatient Services at Bellevue Hospital in Manhattan, hospitalist shifts are a normal part of his job. But he had to give them up during the surge to focus on planning, management, and especially scheduling other doctors, with sufficient backups needed to cover last minute changes. Dr. Fagan did that by using the existing pool of hospitalist staff, physicians who were reassigned from other specialties, agency staff, military medical personnel, and volunteer doctors who flew in from around the country to help. He also worked 10- to 12-hour days for 36 consecutive days.

The impact of disparities in access to care in New York City was reflected in the greater demand for care in the hospitals in Brooklyn, Queens, and the Bronx. “With fewer patients and more hospital beds in Manhattan, we had the capacity to share our beds,” Dr. Fagan said. “It was so amazing to me how quickly we could move patients from one hospital to another. We started accepting up to 40 transfers a day. But hey, we were still really busy.”

Bellevue is the nation’s oldest public hospital. “We care for the homeless, for immigrants, and we don’t ask questions. That’s our mission. I’m so proud to work here, and so grateful,” Dr. Fagan said. “If someone is undocumented or without insurance, I will give them exactly the same care. We stepped up in a big way to care for people of New York, but we’ve always been there for them – and we were there for them during the COVID surge.”

The hospitals in the system also worked together in ways Dr. Fagan had never seen. “It helped to have a central command structure with a bird’s eye view from above the level of individual hospitals, to organize and see which hospitals could step up. It’s good to have the data to put it in perspective,” he said. The system also utilized a temporary low-acuity medical center set up by NYCH+H on Roosevelt Island, as well as field hospitals organized at the Jacob K. Javits Convention Center and the USTA Billie Jean King National Tennis Center.

“At Bellevue we tried to stay ready, with the ability to turn former hospital units that were being used as offices back to beds. We always had three units lined up that were fully ready to convert. For example, I was medical director of the preop clinic and one day they gave us 24 hours to pack everything and move out. Three days later, it was a 24-bed unit. We also built a more robust rapid response and code team,” he said.

“It was hard for me not to take hospitalist shifts, because my identity is being a doctor. I eventually came to terms with the importance of the role that I was doing every day. I felt I could protect my colleagues, and if they were having an emotional day, to give them the opportunity to talk to someone. I also did the onboarding, one-on-one, of the new doctors.”

As the crisis in New York City has ebbed, Dr. Fagan was recently able to again take a week of clinical service. “The first day back on the floor I felt that I had forgotten everything. But by the end of the day, I thought, ‘Okay, I do know how to do this, after all.’ Census is down here. It’s quiet. That’s good. We need it now,” he said.

“I think the hardest moment for me was when the head nurse on our trauma unit, Ernesto DeLeon, known to everybody here, died of COVID in our ICU in April,” Dr. Fagan said. When Mr. DeLeon died, 100 hospital personnel gathered in the halls outside the room to pay their respects. “There had been a palpable fear in our lives – and this showed us that the fear was real. Ernesto was the first person I knew well who died, who acquired COVID at work doing what we’re all doing. We haven’t lost any doctors yet, but when this nurse died, we allowed ourselves to realize that this is personal. In that moment, we needed to allow ourselves to be human.”

Joan Curcio, MD, associate director of medicine at Elmhurst Hospital, said Elmhurst was where the story started for New York City and for NYCH+H. “I trained here and have spent my entire career at this hospital. It came to feel like what a battleground must be like, with things coming at you from every direction,” she said. “It was overwhelming in ways I could not have foreseen. I had seen videos from Italy [an early COVID-19 epicenter], but until it happened here, it was just hard to process.”

Things started slowly, with a few patients with severe acute respiratory distress syndrome and a 5- to 7-day turnaround to get results of their viral infection tests. “By week 2, a greater number of patients from our clinics and testing sites were filtering through the emergency department. Then hundreds.”

The normal occupancy rate for the department of medicine at Elmhurst is 110-115%, which typically means full beds plus patients in the emergency department. “We started to grow to 160, then 180, and then a peak of 250% of occupancy. We took over a rehab surgery floor, then a 35-bed surgery and hospice floor, which went to full capacity just like that,” she said. The number of non–critical care service teams increased to 20, working with redeployed staff, volunteers, military, and agency personnel, while ICU beds increased from 20 to 105.

“We were dealing with a much higher acuity level and enduring emotional turmoil with families, trying to carve out time to call them after our shift was over,” Dr. Curcio explained. Elmhurst developed a call-in hotline and a daily call-out service for families. Technology was mobilized to provide video visits and new systems were designed for isolation and for PPE distribution and use.

“I just felt that I couldn’t get everything done. I felt continually overwhelmed, and it didn’t matter how much time I took. I never felt I was able to give enough to anybody in any area, which was hard to take,” Dr. Curcio said. “But I still felt a sense of purpose and that I was making a difference – thanks to lots of support from the central office.”

Patient volume at Elmhurst is now down, lower than Dr. Curcio has ever seen it. “One of the main issues right now, moving forward, is ‘how do we function in a post-crisis mode?’” she said. The process of transitioning back to non-COVID-19 care will be complex. “When we clear a floor and clean it to go back to being a cold [COVID-19-negative] unit, it’s a whole different level of cleaning that takes 7 days.”

One moment that was particularly jarring for Dr. Curcio occurred while she was giving a tour of the hospital to visiting military medical personnel. “We went into the emergency department and I turned around and looked into a shower room, which was full of body bags. They were all full.”

But the experience has also been inspiring. “People gave their all without complaint. We hospitalists, and all those recruited to act as hospitalists, essentially took responsibility for the COVID response,” she said. “This was, hopefully, the experience of a lifetime as a medical professional. I wouldn’t want to ever experience something as daunting as this again.”

New York City Health + Hospitals (NYCH+H), the country’s largest public health care system, encompasses 11 hospitals with 4,354 staffed acute beds during normal times. It serves as the safety net for 1.1 million of the 8.4 million residents of the most populous city in the United States, many of them uninsured, undocumented, covered by Medicaid, or otherwise disadvantaged.

At the very epicenter in the early days of the historic COVID-19 pandemic, NYCH+H transferred patients between its facilities, added medical and ICU beds by the hundreds, mobilized palliative care volunteers, harnessed telemedicine and a clinician hotline, and made other sweeping changes to ensure that the city’s public health system would be able to respond to demand at the peak of the surge. That peak hit in April, when an average of 9,000 new COVID-19 cases were being reported in the city every day.

Through it all, hospitalists have played critical roles in both planning for the system’s response and caring for severely ill COVID-19 patients. Their stories reflect both the unprecedented demands on the system and the dedication of frontline clinicians.

One of those, Carla Saladini-Aponte, MD, who just finished her residency in June 2019, found herself on the firing line in March 2020 as an attending physician at 457-bed NYCH+H/Jacobi Hospital in the Bronx. “I have experienced so much in my first year on the job, dealing with a disease that we’ve never seen before,” she said. “We didn’t grasp the extent of the COVID crisis in the beginning, so we were emotionally unprepared when it first hit.”

Starting on March 30, NYCH+H administration mobilized a centralized incident command structure to coordinate response systemwide to a rapidly changing situation.

Two weeks later Jacobi was a COVID-19 hospital, top to bottom, with its medical ICU beds increased from 12 to more than 100. By mid-April, Dr. Saladini-Aponte’s team, one of 11 medical teams in the hospital, had 26 patients, all of them with COVID-19. There was not a consensus in the early days on how to manage patients with severe respiratory distress. “But by the time the surge came, we had a better understanding of the scope of the situation,” she said.

Learning to be an attending

“They don’t teach you how to be an attending during residency,” Dr. Saladini-Aponte said. “At the beginning I wasn’t such a good teacher. I just wanted to prove myself and stay one step ahead of the residents. But as an academic hospitalist you have to listen to others. I learned to ask questions of the residents every morning, including how they were doing personally.”

Sometimes a visiting consultant would ask on the floor: “‘Where’s your attending?’” not recognizing Dr. Saladini-Aponte, fresh out of residency, filling that role. At times, she felt like a PGY-4 (postgraduate year 4). But she quickly grew into the attending role and was asked to be site coordinator for the mobilization of palliative medicine volunteers at Jacobi.

“We found ourselves having to make tough ethical decisions. Some patients, even if we provided a ventilator and maximum oxygen therapy, would still die. There were difficult discussions when we didn’t know if we had enough dialysis machines, or how to manage other limited resources. The hospital was saying: You decide, if there’s a high degree of certainty about the outcome. But we had never practiced medicine this way before,” she said.

“That’s why our hospital provided daily ethics meetings with our ethics council. There would be eight people sitting 6 feet apart in a conference room, all wearing masks. We’d talk about situations that were giving us trouble. Their role wasn’t to provide answers but to help us see the scope of the situation and the complexities,” she explained.

Dr. Saladini-Aponte said she has had many sleepless nights since the pandemic began. “Sometimes, I would come home from work and lie down on the floor and cry,” she said. “But we had so much support from volunteers helping our little hospitalist service of seven.” It was also important to keep up with the clinical information, and one of her coworkers created “cheat sheets” for the clinicians, regularly updated with the latest essential information on antibiotics, testing, and the like.

“At the peak, I was trying to read everything I could about the virus. I was just pulling myself in too many directions. I asked for help from my boyfriend to remind me not to log onto my computer when I came home from work,” she said. “One of my techniques for preventing burnout was just to avoid social media. I couldn’t deal with what was going on in the news. It just angered me. Even now, seeing people without masks makes me very uncomfortable.”
 

Organizing the crisis response

As chief value officer for NYCH+H, Hyung (Harry) Cho, MD, FACP, SFHM, typically focuses on issues of patient safety and overuse of medical treatments in the health system. But in the COVID-19 crisis, he found himself at the forefront of organizing its response. “We tried to provide support centrally and to standardize practice in how we test and treat,” he said.

“We were truly at the epicenter of the pandemic,” Dr. Cho said. “All of our hospitals had different experiences, and unique responses. But the system worked well.” Patients were transferred from the more overtaxed hospitals to Bellevue and other NYCH+H hospitals with spare beds. An emergency medical response structure was put in place, and every morning the system’s Tiger Team, with multidisciplinary personnel from administration, operations, logistics, and medical/technical specialists, would gather virtually to discuss needs across the system.

“It was a very open atmosphere and we asked people to report what was happening on the ground,” Dr. Cho said. “We started rapidly reviewing batches of 20 patients at a time for transfer in order to alleviate pressure in the most overtaxed ERs.”

NYCH+H also had to work through concerns about PPE, just like other U.S. hospitals. Treatment guidelines were changing by the day. Medical concerns were relayed at a rapid pace. Another priority was trying to limit unnecessary exposure for staff through a recommendation that only one clinician from a team would go into the room of an infected patient, unless another was absolutely needed.

The reality of public health

NYCH+H was created by the New York State Legislature in 1969 and rebranded in 2015. It includes a low- to no-cost health insurance plan called MetroPlus, along with outpatient centers, comprehensive case management, and social supports in the home.

“What people know about public health systems is that we typically are underresourced. That’s just the reality of public health,” Dr. Cho said. “We help the community, the underserved. The people who truly needed our help are also the ones who have been disproportionately affected by COVID-19. And that is where we really shine as a system.”

Dr. Cho lauded the performance of the health system’s frontline staff. “Watching them come together during the entire pandemic, and do their best every day, was truly inspiring,” he said. “But when they got to the peak, it really took an emotional toll on them.”

NYCH+H’s in-house staff support program, called Helping Healers Heal, was mobilized with specially trained teams at each of its 11 hospitals to provide peer-to-peer support, mental health expertise, and team-debriefing sessions to staff members following traumatic events.

Aspirin alone after transcatheter aortic valve implantation (TAVI) significantly reduced bleeding, compared with aspirin plus clopidogrel, without increasing thromboembolic events, in the latest results from the POPular TAVI study.

“Physicians can easily and safely reduce rate of bleeding by omitting clopidogrel after TAVI,” lead author, Jorn Brouwer, MD, St Antonius Hospital, Nieuwegein, the Netherlands, said.

“Aspirin alone should be used in patients undergoing TAVI who are not on oral anticoagulants and have not recently undergone coronary stenting,” he concluded.

Senior author, Jurriën ten Berg, MD, PhD, also from St Antonius Hospital, said in an interview: “I think we can say for TAVI patients, when it comes to antithrombotic therapy, less is definitely more.”

“This is a major change to clinical practice, with current guidelines recommending 3-6 months of dual antiplatelet therapy after a TAVI procedure,” he added. “We expected that these guidelines will change after our results.”

These latest results from POPular TAVI were presented at the virtual European Society of Cardiology Congress 2020 and simultaneously published online in The New England Journal of Medicine.

The trial was conducted in two cohorts of patients undergoing TAVI. The results from cohort B – in patients who were already taking an anticoagulant for another indication – were reported earlier this year and showed no benefit of adding clopidogrel and an increase in bleeding. Now the current results in cohort A – patients undergoing TAVI who do not have an established indication for long-term anticoagulation – show similar results, with aspirin alone preferred over aspirin plus clopidogrel.

Dr. ten Berg explained that the recommendation for dual antiplatelet therapy (DAPT) was adopted mainly because this has been shown to be beneficial in patients undergoing percutaneous coronary intervention (PCI) with stenting; it was thought the same benefits would be seen in TAVI, which also uses a stent-based delivery system.

“However, TAVI patients are a different population – they are generally much older than PCI patients, with an average age of 80 plus, and they have many more comorbidities, so they are much higher bleeding risk,” Dr. ten Berg explained. “In addition, the catheters used for TAVI are larger than those used for PCI, forcing the femoral route to be employed, and both of these factors increases bleeding risk.”

“We saw that, in the trial, patients on dual antiplatelet therapy had a much greater rate of major bleeding and the addition of clopidogrel did not reduce the risk of major thrombotic events,” such as stroke, myocardial infarction (MI), or cardiovascular (CV) death.

Given that the TAVI procedure is associated with an increase in stroke in the immediate few days after the procedure, it would seem logical that increased antiplatelet therapy would be beneficial in reducing this, Dr. ten Berg noted.

“But this is not what we are seeing,” he said. “The stroke incidence was similar in the two groups in POPular TAVI. This suggests that the strokes may not be platelet mediated. They might be caused by another mechanism, such as dislodgement of calcium from the valve or tissue from the aorta.”

For the current part of the study, 690 patients who were undergoing TAVI and did not have an indication for long-term anticoagulation were randomly assigned to receive aspirin alone or aspirin plus clopidogrel for 3 months.

The two primary outcomes were all bleeding (including minor, major, and life-threatening or disabling bleeding) and non–procedure-related bleeding over a period of 12 months. Most bleeding at the TAVI puncture site was counted as not procedure related.

Results showed that a bleeding event occurred in 15.1% of patients receiving aspirin alone and 26.6% of those receiving aspirin plus clopidogrel (risk ratio, 0.57; P = .001). Non–procedure-related bleeding occurred 15.1% of patients receiving aspirin alone vs 24.9% of those receiving aspirin plus clopidogrel (risk ratio, 0.61; P = .005). Major, life-threatening, or disabling bleeding occurred in 5.1% of the aspirin-alone group versus 10.8% of those in the aspirin plus clopidogrel group.

Two secondary outcomes included thromboembolic events. The secondary composite one endpoint of death from cardiovascular causes, non–procedure-related bleeding, stroke, or MI at 1 year occurred in 23.0% of those receiving aspirin alone and in 31.1% of those receiving aspirin plus clopidogrel (difference, −8.2 percentage points; P for noninferiority < .001; risk ratio, 0.74; P for superiority = .04).

The secondary composite two endpoint of death from cardiovascular causes, ischemic stroke, or MI at 1 year occurred in 9.7% of the aspirin-alone group versus 9.9% of the dual-antiplatelet group (difference, −0.2 percentage points; P for noninferiority = .004; risk ratio, 0.98; P for superiority = .93).

Dr. ten Berg pointed out that the trial was not strictly powered to look at thrombotic events, but he added: “There was no hint of an increase in the aspirin-alone group and there was quite a high event rate, so we should have seen something if it was there.”

The group has also performed a meta-analysis of these results, with some previous smaller studies also comparing aspirin and DAPT in TAVI which again showed no reduction in thrombotic events with dual-antiplatelet therapy.

Dr. ten Berg noted that the trial included all-comer TAVI patients. “The overall risk was quite a low [STS score, 2.5]. This is a reflection of the typical TAVI patient we are seeing but I would say our results apply to patients of all risk.”
 

Simplifies and clarifies

Discussant of the trial at the ESC Hotline session, Anna Sonia Petronio, MD, Azienda Ospedaliero-Universitaria Pisana, Pisa, Italy, said, “This was an excellent and essential study that simplifies and clarifies aspects of TAVI treatment and needs to change the guidelines.”

“These results will have a large impact on clinical practice in this elderly population,” she said. But she added that more data are needed for younger patients and more complicated cases, such as valve-in-valve and bicuspid valves.

Commenting on the results, Robert Bonow, MD, Northwestern University, Chicago, said, “The optimal antithrombotic management of patients undergoing TAVI who do not otherwise have an indication for anticoagulation [such as atrial fibrillation] has been uncertain and debatable. Aspirin plus clopidogrel for 3-6 months has been the standard, based on the experience with coronary stents.”

“Thus, the current results of cohort A of the POPular TAVI trial showing significant reduction in bleeding events with aspirin alone compared to DAPT for 3 months, with no difference in ischemic events, are important observations,” he said. “It is noteworthy that most of the bleeding events occurred in the first 30 days.

“This is a relatively small randomized trial, so whether these results will be practice changing will depend on confirmation by additional studies, but it is reassuring to know that patients at higher risk for bleeding would appear to do well with low-dose aspirin alone after TAVI,” Dr. Bonow added.

“These results complete the circle in terms of antithrombotic therapy after TAVI,” commented Michael Reardon, MD, Houston Methodist DeBakey Heart & Vascular Institute, Texas.

“I would add two caveats: First is that most of the difference in the primary endpoint occurs in the first month and levels out between the groups after that,” Dr. Reardon said. “Second is that this does not address the issue of leaflet thickening and immobility.”

Ashish Pershad, MD, Banner – University Medicine Heart Institute, Phoenix, added: “This trial answers a very important question and shows dual-antiplatelet therapy is hazardous in TAVI patients. Clopidogrel is not needed.”

Dr. Pershad says he still wonders about patients who receive very small valves who may have a higher risk for valve-induced thrombosis. “While there were some of these patients in the trial, the numbers were small, so we need more data on this group,” he commented.

“But for bread-and-butter TAVI, aspirin alone is the best choice, and the previous results showed, for patients already taking oral anticoagulation, no additional antithrombotic therapy is required,” Dr. Pershad concluded. “This is a big deal and will change the way we treat patients.”

 The POPular trial was supported by the Netherlands Organization for Health Research and Development. Brouwer reports no disclosures.

Dr. ten Berg explained that the recommendation for dual antiplatelet therapy (DAPT) was adopted mainly because this has been shown to be beneficial in patients undergoing percutaneous coronary intervention (PCI) with stenting; it was thought the same benefits would be seen in TAVI, which also uses a stent-based delivery system.

“However, TAVI patients are a different population – they are generally much older than PCI patients, with an average age of 80 plus, and they have many more comorbidities, so they are much higher bleeding risk,” Dr. ten Berg explained. “In addition, the catheters used for TAVI are larger than those used for PCI, forcing the femoral route to be employed, and both of these factors increases bleeding risk.”

“We saw that, in the trial, patients on dual antiplatelet therapy had a much greater rate of major bleeding and the addition of clopidogrel did not reduce the risk of major thrombotic events,” such as stroke, myocardial infarction (MI), or cardiovascular (CV) death.

Given that the TAVI procedure is associated with an increase in stroke in the immediate few days after the procedure, it would seem logical that increased antiplatelet therapy would be beneficial in reducing this, Dr. ten Berg noted.

“But this is not what we are seeing,” he said. “The stroke incidence was similar in the two groups in POPular TAVI. This suggests that the strokes may not be platelet mediated. They might be caused by another mechanism, such as dislodgement of calcium from the valve or tissue from the aorta.”

For the current part of the study, 690 patients who were undergoing TAVI and did not have an indication for long-term anticoagulation were randomly assigned to receive aspirin alone or aspirin plus clopidogrel for 3 months.

The two primary outcomes were all bleeding (including minor, major, and life-threatening or disabling bleeding) and non–procedure-related bleeding over a period of 12 months. Most bleeding at the TAVI puncture site was counted as not procedure related.

Results showed that a bleeding event occurred in 15.1% of patients receiving aspirin alone and 26.6% of those receiving aspirin plus clopidogrel (risk ratio, 0.57; P = .001). Non–procedure-related bleeding occurred 15.1% of patients receiving aspirin alone vs 24.9% of those receiving aspirin plus clopidogrel (risk ratio, 0.61; P = .005). Major, life-threatening, or disabling bleeding occurred in 5.1% of the aspirin-alone group versus 10.8% of those in the aspirin plus clopidogrel group.

Two secondary outcomes included thromboembolic events. The secondary composite one endpoint of death from cardiovascular causes, non–procedure-related bleeding, stroke, or MI at 1 year occurred in 23.0% of those receiving aspirin alone and in 31.1% of those receiving aspirin plus clopidogrel (difference, −8.2 percentage points; P for noninferiority < .001; risk ratio, 0.74; P for superiority = .04).

The secondary composite two endpoint of death from cardiovascular causes, ischemic stroke, or MI at 1 year occurred in 9.7% of the aspirin-alone group versus 9.9% of the dual-antiplatelet group (difference, −0.2 percentage points; P for noninferiority = .004; risk ratio, 0.98; P for superiority = .93).

Dr. ten Berg pointed out that the trial was not strictly powered to look at thrombotic events, but he added: “There was no hint of an increase in the aspirin-alone group and there was quite a high event rate, so we should have seen something if it was there.”

The group has also performed a meta-analysis of these results, with some previous smaller studies also comparing aspirin and DAPT in TAVI which again showed no reduction in thrombotic events with dual-antiplatelet therapy.

Dr. ten Berg noted that the trial included all-comer TAVI patients. “The overall risk was quite a low [STS score, 2.5]. This is a reflection of the typical TAVI patient we are seeing but I would say our results apply to patients of all risk.”
 

Simplifies and clarifies

Discussant of the trial at the ESC Hotline session, Anna Sonia Petronio, MD, Azienda Ospedaliero-Universitaria Pisana, Pisa, Italy, said, “This was an excellent and essential study that simplifies and clarifies aspects of TAVI treatment and needs to change the guidelines.”

“These results will have a large impact on clinical practice in this elderly population,” she said. But she added that more data are needed for younger patients and more complicated cases, such as valve-in-valve and bicuspid valves.

Commenting on the results, Robert Bonow, MD, Northwestern University, Chicago, said, “The optimal antithrombotic management of patients undergoing TAVI who do not otherwise have an indication for anticoagulation [such as atrial fibrillation] has been uncertain and debatable. Aspirin plus clopidogrel for 3-6 months has been the standard, based on the experience with coronary stents.”

“Thus, the current results of cohort A of the POPular TAVI trial showing significant reduction in bleeding events with aspirin alone compared to DAPT for 3 months, with no difference in ischemic events, are important observations,” he said. “It is noteworthy that most of the bleeding events occurred in the first 30 days.

“This is a relatively small randomized trial, so whether these results will be practice changing will depend on confirmation by additional studies, but it is reassuring to know that patients at higher risk for bleeding would appear to do well with low-dose aspirin alone after TAVI,” Dr. Bonow added.

“These results complete the circle in terms of antithrombotic therapy after TAVI,” commented Michael Reardon, MD, Houston Methodist DeBakey Heart & Vascular Institute, Texas.

“I would add two caveats: First is that most of the difference in the primary endpoint occurs in the first month and levels out between the groups after that,” Dr. Reardon said. “Second is that this does not address the issue of leaflet thickening and immobility.”

Ashish Pershad, MD, Banner – University Medicine Heart Institute, Phoenix, added: “This trial answers a very important question and shows dual-antiplatelet therapy is hazardous in TAVI patients. Clopidogrel is not needed.”

Dr. Pershad says he still wonders about patients who receive very small valves who may have a higher risk for valve-induced thrombosis. “While there were some of these patients in the trial, the numbers were small, so we need more data on this group,” he commented.

“But for bread-and-butter TAVI, aspirin alone is the best choice, and the previous results showed, for patients already taking oral anticoagulation, no additional antithrombotic therapy is required,” Dr. Pershad concluded. “This is a big deal and will change the way we treat patients.”

Aspirin alone after transcatheter aortic valve implantation (TAVI) significantly reduced bleeding, compared with aspirin plus clopidogrel, without increasing thromboembolic events, in the latest results from the POPular TAVI study.

“Physicians can easily and safely reduce rate of bleeding by omitting clopidogrel after TAVI,” lead author, Jorn Brouwer, MD, St Antonius Hospital, Nieuwegein, the Netherlands, said.

“Aspirin alone should be used in patients undergoing TAVI who are not on oral anticoagulants and have not recently undergone coronary stenting,” he concluded.

Senior author, Jurriën ten Berg, MD, PhD, also from St Antonius Hospital, said in an interview: “I think we can say for TAVI patients, when it comes to antithrombotic therapy, less is definitely more.”

“This is a major change to clinical practice, with current guidelines recommending 3-6 months of dual antiplatelet therapy after a TAVI procedure,” he added. “We expected that these guidelines will change after our results.”

These latest results from POPular TAVI were presented at the virtual European Society of Cardiology Congress 2020 and simultaneously published online in The New England Journal of Medicine.

The trial was conducted in two cohorts of patients undergoing TAVI. The results from cohort B – in patients who were already taking an anticoagulant for another indication – were reported earlier this year and showed no benefit of adding clopidogrel and an increase in bleeding. Now the current results in cohort A – patients undergoing TAVI who do not have an established indication for long-term anticoagulation – show similar results, with aspirin alone preferred over aspirin plus clopidogrel.

Breast milk is an unlikely source of transmission of SARS-CoV-2 from mothers to infants, according to data from case reports and breast milk samples from 18 women.

“To date, SARS-CoV-2 has not been isolated from breast milk, and there are no documented cases of transmission of infectious virus to the infant through breast milk,” but the potential for transmission remains a concern among women who want to breastfeed, wrote Christina Chambers, PhD, of the University of California, San Diego, and colleagues.

In a research letter published in JAMA, the investigators identified 18 women with confirmed SARS-CoV-2 infections (all but 1 of the women had symptomatic COVID-19 disease) and infants aged 0-19 months between March 27 and May 6, 2020. The average age of the mothers was 34 years, and 78% were non-Hispanic White. The women provided 1-12 samples of breast milk for a total of 64 samples collected before and after positive COVID-19 tests.

One sample yielded detectable RNA from SARS-CoV-2 and was collected on the day of the woman’s symptom onset. However, one sample taken 2 days prior to symptom onset and two samples collected 12 and 41 days later tested negative for viral RNA, the researchers said. In addition, no replication-competent virus was identified in the positive sample or any of the other samples.

The researchers spiked two stored milk samples collected prior to the pandemic with replication-competent SARS-CoV-2. Virus was not detected by culture in the samples after Holder pasteurization, but was detected by culture in nonpasteurized aliquots of the same samples.

“These data suggest that SARS-CoV-2 RNA does not represent replication-competent virus and that breast milk may not be a source of infection for the infant,” Dr. Chambers and associates said.

The results were limited by several factors including the small sample size and potential for selection bias, as well as the use of self-reports of positive tests and self-collection of breast milk, the researchers noted. However, the findings are reassuring in light of the known benefits of breastfeeding and the use of milk banks.

“This research is important because the pandemic is ongoing and has far-reaching consequences: as the authors indicate, the potential for viral transmission through breast milk remains a critical question for women infected with SARS-CoV-2 who wish to breastfeed,” Janet R. Hardy, PhD, MPH, MSc, a consultant on global maternal-child health and pharmacoepidemiology, said in an interview.

“This virus has everyone on a rapid learning track, and all information that helps build evidence to support women’s decision-making in the care of their children is valuable,” she said. “These findings suggest that breast milk may not be a source of SARS-CoV-2 infection for the infant. They provide some reassurance given the recognized benefits of breastfeeding and human milk.”

However, “This study is very specific to breast milk,” she emphasized. “In advising women infected with SARS-CoV-2, clinicians may want to include a discussion of protection methods to prevent maternal transmission of the virus through respiratory droplets.”

Although the data are preliminary, “the investigators established and validated an RT-PCR [reverse transcription polymerase chain reaction] assay and developed tissue culture methods for replication-competent SARS-CoV-2 in breast milk, both valuable tools for further studies. Next steps will include controlled studies of greater sample size with independent verification of RT-PCR positivity,” said Dr. Hardy, a consultant to Biohaven Pharmaceuticals, New Haven, Conn.

The study was supported by the National Institute of Allergy and Infectious Diseases, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, and the National Institute of Mental Health. Medela Corporation provided milk sample collection materials. The Family Larsson-Rosenquist Foundation provided an unrestricted COVID19 emergency gift fund.

The mortality burden associated with dementia may be 2.7 times greater than estimated, according to an analysis of a prospective cohort study. This burden may be greatest among non-Hispanic black older adults, compared with Hispanic and non-Hispanic whites. This burden also is significantly greater among people with less than a high school education, compared with those with a college education.

The study results underscore the importance of broadening access to population-based interventions that focus on dementia prevention and care, the investigators wrote. “Future research could examine the extent to which deaths attributable to dementia and underestimation of dementia as an underlying cause of death on death certificates might have changed over time,” wrote Andrew C. Stokes, PhD, assistant professor of global health at the Boston University School of Public Health, and colleagues.

The study was published online Aug. 24 in JAMA Neurology.

In 2019, approximately 5.6 million adults in the United States who were aged 65 years or older had Alzheimer’s disease, vascular dementia, or mixed-cause dementia. A further 18.8% of Americans in this age group had cognitive impairment without dementia (CIND). About one third of patients with CIND may develop Alzheimer’s disease or related dementias (ADRD) within 5 years.

Research suggests that medical examiners significantly underreport ADRD on death certificates. One community-based study, for example, found that only 25% of deaths in patients with dementia had Alzheimer’s disease listed on the death certificates. Other research found that deaths in patients with dementia were often coded using more proximate causes, such as cardiovascular disease, sepsis, and pneumonia.
 

Health and retirement study

Dr. Stokes and colleagues examined data from the Health and Retirement Study (HRS) to evaluate the association of dementia and CIND with all-cause mortality. The HRS is a longitudinal cohort study of adults older than 50 years who live in the community. Its sample is nationally representative. The HRS investigators also initiated the Aging, Demographics, and Memory study to develop a procedure for assessing cognitive status in the HRS sample.

In their study, Dr. Stokes and colleagues included adults who had been sampled in the 2000 wave of HRS. They focused on participants between ages 70 and 99 years at baseline, and their final sample included 7,342 older adults. To identify dementia status, the researchers used the Langa–Weir score cutoff, which is based on tests of immediate and delayed recall of 10 words, a serial 7-second task, and a backward counting task. They also classified dementia status using the Herzog–Wallace, Wu, Hurd, and modified Hurd algorithms.

At baseline, the researchers measured age, sex, race or ethnicity, educational attainment, smoking status, self-reported disease diagnoses, and U.S. Census division as covariates. The National Center for Health Statistics linked HRS data with National Death Index records. These linked records include underlying cause of death and any mention of a condition or cause of death on the death certificate. The researchers compared the percentage of deaths attributable to ADRD according to a population attributable fraction estimate with the proportion of dementia-related deaths according to underlying causes and with any mention of dementia on death certificates.

The sample of 7,342 older adults included 4,348 (60.3%) women. Data for 1,030 (13.4%) people were reported by proxy. At baseline, most participants (64.0%) were between ages 70 and 79 years, 31% were between ages 80 and 89, and 5% were between ages 90 and 99 years. The prevalence of dementia in the complete sample was 14.3%, and the prevalence of CIND was 24.7%. The prevalence of dementia (22.4%) and CIND (29.3%) was higher among decedents than among the full population.

The hazard ratio (HR) for mortality was 2.53 among participants with dementia and 1.53 among patients with CIND. Although 13.6% of deaths were attributable to dementia, the proportion of deaths assigned to dementia as an underlying cause on death certificates was 5.0%. This discrepancy suggests that dementia is underreported by more than a factor of 2.7.

The mortality burden of dementia was 24.7% in non-Hispanic black older adults, 20.7% in Hispanic white participants, and 12.2% in non-Hispanic white participants. In addition, the mortality burden of dementia was significantly greater among participants with less than a high school education (16.2%) than among participants with a college education (9.8%).

The degree to which the underlying cause of death underestimated the mortality burden of dementia varied by sociodemographic characteristics, health status, and geography. The burden was underestimated by a factor of 7.1 among non-Hispanic black participants, a factor of 4.1 among Hispanic participants, and a factor of 2.3 among non-Hispanic white participants. The burden was underestimated by a factor of 3.5 in men and a factor of 2.4 in women. In addition, the burden was underestimated by a factor of 3.0 among participants with less than a high school education, by a factor of 2.3 among participants with a high school education, by a factor of 1.9 in participants with some college, and by a factor of 2.5 among participants with a college or higher education.

One of the study’s strengths was its population attributable fraction analysis, which reduced the risk of overestimating the mortality burden of dementia, Dr. Stokes and colleagues wrote. Examining CIND is valuable because of its high prevalence and consequent influence on outcomes in the population, even though CIND is associated with a lower mortality risk, they added. Nevertheless, the investigators were unable to assess mortality for dementia subtypes, and the classifications of dementia status and CIND may be subject to measurement error.
 

Underestimation is systematic

“This study is eye-opening in that it highlights the systematic underestimation of deaths attributable to dementia,” said Costantino Iadecola, MD, Anne Parrish Titzell professor of neurology and director and chair of the Feil Family Brain and Mind Research Institute at Weill Cornell Medicine in New York. The study’s main strength is that it is nationally representative, but the data must be confirmed in a larger population, he added.

The results will clarify the effect of dementia on mortality for neurologists, and geriatricians should be made aware of them, said Dr. Iadecola. “These data should be valuable to rationalize public health efforts and related funding decisions concerning research and community support.”

Further research could determine the mortality of dementia subgroups, “especially dementias linked to vascular factors in which prevention may be effective,” said Dr. Iadecola. “In the older population, vascular factors may play a more preeminent role, and it may help focus preventive approaches.”

The study was supported by a grant from the National Institute on Aging. Dr. Stokes received grants from Ethicon that were unrelated to this study. Dr. Iadecola serves on the scientific advisory board of Broadview Venture.

The study results underscore the importance of broadening access to population-based interventions that focus on dementia prevention and care, the investigators wrote. “Future research could examine the extent to which deaths attributable to dementia and underestimation of dementia as an underlying cause of death on death certificates might have changed over time,” wrote Andrew C. Stokes, PhD, assistant professor of global health at the Boston University School of Public Health, and colleagues.

The study was published online Aug. 24 in JAMA Neurology.

In 2019, approximately 5.6 million adults in the United States who were aged 65 years or older had Alzheimer’s disease, vascular dementia, or mixed-cause dementia. A further 18.8% of Americans in this age group had cognitive impairment without dementia (CIND). About one third of patients with CIND may develop Alzheimer’s disease or related dementias (ADRD) within 5 years.

Research suggests that medical examiners significantly underreport ADRD on death certificates. One community-based study, for example, found that only 25% of deaths in patients with dementia had Alzheimer’s disease listed on the death certificates. Other research found that deaths in patients with dementia were often coded using more proximate causes, such as cardiovascular disease, sepsis, and pneumonia.
 

Health and retirement study

Dr. Stokes and colleagues examined data from the Health and Retirement Study (HRS) to evaluate the association of dementia and CIND with all-cause mortality. The HRS is a longitudinal cohort study of adults older than 50 years who live in the community. Its sample is nationally representative. The HRS investigators also initiated the Aging, Demographics, and Memory study to develop a procedure for assessing cognitive status in the HRS sample.

In their study, Dr. Stokes and colleagues included adults who had been sampled in the 2000 wave of HRS. They focused on participants between ages 70 and 99 years at baseline, and their final sample included 7,342 older adults. To identify dementia status, the researchers used the Langa–Weir score cutoff, which is based on tests of immediate and delayed recall of 10 words, a serial 7-second task, and a backward counting task. They also classified dementia status using the Herzog–Wallace, Wu, Hurd, and modified Hurd algorithms.

At baseline, the researchers measured age, sex, race or ethnicity, educational attainment, smoking status, self-reported disease diagnoses, and U.S. Census division as covariates. The National Center for Health Statistics linked HRS data with National Death Index records. These linked records include underlying cause of death and any mention of a condition or cause of death on the death certificate. The researchers compared the percentage of deaths attributable to ADRD according to a population attributable fraction estimate with the proportion of dementia-related deaths according to underlying causes and with any mention of dementia on death certificates.

The sample of 7,342 older adults included 4,348 (60.3%) women. Data for 1,030 (13.4%) people were reported by proxy. At baseline, most participants (64.0%) were between ages 70 and 79 years, 31% were between ages 80 and 89, and 5% were between ages 90 and 99 years. The prevalence of dementia in the complete sample was 14.3%, and the prevalence of CIND was 24.7%. The prevalence of dementia (22.4%) and CIND (29.3%) was higher among decedents than among the full population.

The hazard ratio (HR) for mortality was 2.53 among participants with dementia and 1.53 among patients with CIND. Although 13.6% of deaths were attributable to dementia, the proportion of deaths assigned to dementia as an underlying cause on death certificates was 5.0%. This discrepancy suggests that dementia is underreported by more than a factor of 2.7.

The mortality burden of dementia was 24.7% in non-Hispanic black older adults, 20.7% in Hispanic white participants, and 12.2% in non-Hispanic white participants. In addition, the mortality burden of dementia was significantly greater among participants with less than a high school education (16.2%) than among participants with a college education (9.8%).

The degree to which the underlying cause of death underestimated the mortality burden of dementia varied by sociodemographic characteristics, health status, and geography. The burden was underestimated by a factor of 7.1 among non-Hispanic black participants, a factor of 4.1 among Hispanic participants, and a factor of 2.3 among non-Hispanic white participants. The burden was underestimated by a factor of 3.5 in men and a factor of 2.4 in women. In addition, the burden was underestimated by a factor of 3.0 among participants with less than a high school education, by a factor of 2.3 among participants with a high school education, by a factor of 1.9 in participants with some college, and by a factor of 2.5 among participants with a college or higher education.

One of the study’s strengths was its population attributable fraction analysis, which reduced the risk of overestimating the mortality burden of dementia, Dr. Stokes and colleagues wrote. Examining CIND is valuable because of its high prevalence and consequent influence on outcomes in the population, even though CIND is associated with a lower mortality risk, they added. Nevertheless, the investigators were unable to assess mortality for dementia subtypes, and the classifications of dementia status and CIND may be subject to measurement error.
 

Underestimation is systematic

“This study is eye-opening in that it highlights the systematic underestimation of deaths attributable to dementia,” said Costantino Iadecola, MD, Anne Parrish Titzell professor of neurology and director and chair of the Feil Family Brain and Mind Research Institute at Weill Cornell Medicine in New York. The study’s main strength is that it is nationally representative, but the data must be confirmed in a larger population, he added.

The results will clarify the effect of dementia on mortality for neurologists, and geriatricians should be made aware of them, said Dr. Iadecola. “These data should be valuable to rationalize public health efforts and related funding decisions concerning research and community support.”

Further research could determine the mortality of dementia subgroups, “especially dementias linked to vascular factors in which prevention may be effective,” said Dr. Iadecola. “In the older population, vascular factors may play a more preeminent role, and it may help focus preventive approaches.”

The study was supported by a grant from the National Institute on Aging. Dr. Stokes received grants from Ethicon that were unrelated to this study. Dr. Iadecola serves on the scientific advisory board of Broadview Venture.

The mortality burden associated with dementia may be 2.7 times greater than estimated, according to an analysis of a prospective cohort study. This burden may be greatest among non-Hispanic black older adults, compared with Hispanic and non-Hispanic whites. This burden also is significantly greater among people with less than a high school education, compared with those with a college education.

In a previous column, I addressed some of the issues that quickly arose in the context of the COVID-19 pandemic and their implications for reproductive psychiatry. These issues ranged from the importance of sustaining well-being in pregnant and postpartum women during the pandemic, to temporary restrictions that were in place during the early part of the pandemic with respect to performing infertility procedures, to the practical issues of limiting the number of people who could attend to women during labor and delivery in the hospital.

Five months later, we’ve learned a great deal about trying to sustain emotional well-being among pregnant women during COVID-19. There is a high rate of anxiety among women who are pregnant and women who have particularly young children around the various issues of juggling activities of daily living during the pandemic, including switching to remote work and homeschooling children. There is fear of contracting COVID-19 during pregnancy, the exact effects of which are still somewhat unknown. We have seen a shift to telemedicine for prenatal and postpartum obstetrics visits, and a change with respect to visitors and even in-home nurses that would help during the first weeks of life for some couples.

We wondered whether we would see a falloff in the numbers of women presenting to our clinic with questions about the reproductive safety of taking psychiatric medications during pregnancy. We were unclear as to whether women would defer plans to get pregnant given some of the uncertainties that have come with COVID-19. What we’ve seen, at least early on in the pandemic in Massachusetts, has been the opposite. More women during the first 4 months of the pandemic have been seen in our center compared with the same corresponding period over the last 5 years. The precise reasons for this are unclear, but one reason may be that shifting the practice of reproductive psychiatry and pregnancy planning for reproductive-age women to full virtual care has dropped the number of missed appointments to essentially zero. Women perhaps feel an urgency to have a plan for using psychiatric medication during pregnancy. They may also see the benefit of being able to have extended telemedicine consultations that frequently involve their partners, a practice we have always supported, but posed logistical challenges for some.

As our colleagues learned that we had shifted our clinical rounds at the Center for Women’s Mental Health, which we’ve been doing for 25 years, to a virtual format, we began offering a free 1-hour forum to discuss relevant issues around caring for psychiatrically ill women, with a focus on some of the issues that were particularly relevant during the pandemic. The most common reasons for consultation on our service are the appropriate, safest use of antidepressants and mood stabilizers during pregnancy, and that continues to be the case.

If there has been one guiding principle in treating perinatal depression during pregnancy, it has been our long-standing, laser-like focus on keeping women emotionally well during pregnancy, and to highlight the importance of this with women during consultations prior to and during pregnancy. Relapse of psychiatric disorder during pregnancy is one the strongest predictors of postpartum depression, and the impact of untreated depression during pregnancy has been described in the literature and over the years in this column. However, the implications of having severe relapse of a mood disorder, for example, such as depression or bipolar disorder during the pandemic, takes on a new context where we want to minimize, if possible, severe onset of illness requiring hospitalization or emergent attention considering it may make social distancing and some of the other mitigating factors vis-à-vis COVID-19 more challenging.

Despite the accumulated data over the last 2 decades on the reproductive safety of antidepressants, women continue to have questions about the safety of these medications during pregnancy. Studies show now that many women would prefer, if at all possible, to defer treatment with antidepressants, and so they come to us with questions about their reproductive safety, the potential of switching to nonpharmacologic interventions, and the use of alternative interventions that might be used to treat their underlying mood disorder.

Investigators at the University of British Columbia recently have tried to inform the field with still another look, not at reproductive safety per se, but at risk of relapse of depression if women discontinue those medicines during pregnancy.¹ There is a timeliness to this investigation, which was a systematic review and meta-analysis of studies that met a priori criteria for inclusion. Since some of our own group’s early work over 15 years ago on relapse of psychiatric disorder during pregnancy,² which indicated a substantial difference in risk of relapse between women who continued versus who discontinued antidepressants, other investigators have showed the difference in risk for relapse is not as substantial, and that continuation of medication did not appear to mitigate risk for relapse. In fact, in the systematic review, the investigators demonstrated that as a group, maintaining medicine did not appear to confer particular benefit to patients relative to risk for relapse compared to discontinuation of antidepressants.

However, looking more closely, Bayrampour and colleagues note for women with histories of more severe recurrent, major depression, relapse did in fact appear to be greater in women who discontinued compared with those with cases of mild to moderate depression. It is noteworthy that in both our early and later work, and certainly dovetailing with our clinical practice, we have noted severity of illness does not appear to correlate with the actual decisions women ultimately make regarding what they will do with antidepressants. Specifically, some women with very severe illness histories will discontinue antidepressants regardless of their risk for relapse. Alternatively, women with mild to moderate illness will sometimes elect to stay on antidepressant therapy. With all the information that we have about fetal exposure to antidepressants on one hand, the “unknown unknowns” are an understandable concern to both patients and clinicians. Clinicians are faced with the dilemma of how to best counsel women on continuing or discontinuing antidepressants as they plan to conceive or during pregnancy and in the postpartum period.

The literature cited and clinical experience over the last 3 decades suggests rather strongly that there is a relatively low likelihood women with histories of severe recurrent disease will be able to successfully discontinue antidepressants in the absence of relapse. A greater question is, what is the best way to proceed for women who have been on maintenance therapy and had more moderate symptoms?

I am inspired by some of the more recent literature that has tried to elucidate the role of nonpharmacologic interventions such as mindfulness-based cognitive therapy (MBCT) in an effort to mitigate risk for depressive relapse in pregnant women who are well with histories of depression. To date, data do not inform the question as to whether MBCT can be used to mitigate risk of depressive relapse in pregnant women who continue or discontinue antidepressants. That research question is actively being studied by several investigators, including ourselves.

Of particular interest is whether the addition of mindfulness practices such as MBCT in treatment could mitigate risk for depressive relapse in pregnant women who continue or discontinue antidepressant treatment, as that would certainly be a no-harm intervention that could mitigate risk even in a lower risk sample of patients. The question of how to “thread the needle” during the pandemic and best approach woman with a history of recurrent major depression on antidepressants is particularly timely and critical.

Regardless, we make clinical decisions collaboratively with patients based on their histories and individual wishes, and perhaps what we have learned over the last 5 months is the use of telemedicine does afford us the opportunity, regardless of the decisions that patients make, to more closely follow the clinical trajectory of women during pregnancy and the postpartum period so that regardless of treatment, we have an opportunity to intervene early when needed and to ascertain changes in clinical status early to mitigate the risk of frank relapse. From a reproductive psychiatric point of view, that is a silver lining with respect to the associated challenges that have come along with the pandemic.

To date, data do not inform the question as to whether MBCT can be used to mitigate risk of depressive relapse in pregnant women who continue or discontinue antidepressants. That research question is actively being studied by several investigators, including ourselves.

Of particular interest is whether the addition of mindfulness practices such as MBCT in treatment could mitigate risk for depressive relapse in pregnant women who continue or discontinue antidepressant treatment, as that would certainly be a no-harm intervention that could mitigate risk even in a lower risk sample of patients. The question of how to “thread the needle” during the pandemic and best approach woman with a history of recurrent major depression on antidepressants is particularly timely and critical.

Regardless, we make clinical decisions collaboratively with patients based on their histories and individual wishes, and perhaps what we have learned over the last 5 months is the use of telemedicine does afford us the opportunity, regardless of the decisions that patients make, to more closely follow the clinical trajectory of women during pregnancy and the postpartum period so that regardless of treatment, we have an opportunity to intervene early when needed and to ascertain changes in clinical status early to mitigate the risk of frank relapse. From a reproductive psychiatric point of view, that is a silver lining with respect to the associated challenges that have come along with the pandemic.

The US Food and Drug Administration (FDA) has approved marketing of the first authorized diagnostic antigen test for SARS-CoV-2 that can be used without an analyzer.

Abbott

The BinaxNOW COVID-19 Ag Card (Abbott) is similar in some ways to a home pregnancy test. Clinicians read results on a card – one line for a negative result, two lines for positive.

A health care provider swabs a symptomatic patient’s nose, twirls the sample on a test card with a reagent, and waits approximately 15 minutes for results. No additional equipment is required.

Abbott expects the test to cost about $5.00, the company announced.

Office-based physicians, ED physicians, and school nurses could potentially use the product as a point-of-care test. The FDA granted the test emergency use authorization. It is approved for people suspected of having COVID-19 who are within 7 days of symptom onset.

“This new COVID-19 antigen test is an important addition to available tests because the results can be read in minutes, right off the testing card,” Jeff Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological Health, wrote in a news release. “This means people will know if they have the virus in almost real time.”

“This fits into the testing landscape as a simple, inexpensive test that does not require additional equipment,” Marcus Lynch, PhD, assistant manager of the Health Care Horizon Scanning program at ECRI, told Medscape Medical News when asked to comment. ECRI is an independent, nonprofit organization that reviews and analyses COVID-19 therapeutics and diagnostics.

The test could help with early triage of patients who test positive, perhaps alerting physicians to the need to start COVID-19 therapy, added Lynch, who specializes in immunology and vaccine development. The test also could be useful in low-resource settings.

The FDA included a caveat: antigen tests are generally less sensitive than molecular assays. “Due to the potential for decreased sensitivity compared to molecular assays, negative results from an antigen test may need to be confirmed with a molecular test prior to making treatment decisions,” the agency noted.

Lynch agreed and said that when a patient tests negative, physicians still need to use their clinical judgment on the basis of symptoms and other factors. The test is not designed for population-based screening of asymptomatic people, he added.

Abbott announced plans to make up to 50 million tests available per month in the United States starting in October. The product comes with a free smartphone app that people can use to share results with an employer or with others as needed.

As communities wrestle with the decision to send children back to school or opt for distance learning, a key question is how many children are likely to have asymptomatic SARS-CoV-2 infections. Researchers have now found that the prevalence of asymptomatic infections in children correlates with the overall incidence of COVID-19 in the local population, according to an analysis of data from 28 U.S. children’s hospitals.

“The strong association between prevalence of SARS-CoV-2 in children who are asymptomatic and contemporaneous weekly incidence of COVID-19 in the general population ... provides a simple means for institutions to estimate local pediatric asymptomatic prevalence from the publicly available Johns Hopkins University database,” researchers say in an article published online August 25 in JAMA Pediatrics.

Ana Marija Sola, BS, a researcher at the University of California, San Francisco, and colleagues examined the prevalence of SARS-CoV-2 infection among 33,041 children who underwent routine testing in April and May when hospitals resumed elective medical and surgical care. The hospitals performed reverse transcription–polymerase chain reaction tests for SARS-CoV-2 RNA before surgery, clinic visits, or hospital admissions. Pediatric otolaryngologists reported the prevalence data through May 29 as part of a quality improvement project.

In all, 250 patients tested positive for the virus, for an overall prevalence of 0.65%. Across 25 geographic areas, the prevalence ranged from 0% to 2.2%. By region, prevalence was highest in the Northeast, at 0.90%, and the Midwest, at 0.87%; prevalence was lower in the West, at 0.59%, and the South, at 0.52%.

To get a sense of how those rates compared with overall rates in the same geographic areas, the researchers used the Johns Hopkins University confirmed cases database to calculate the average weekly incidence of COVID-19 for the entire population for each geographic area.

“Asymptomatic pediatric prevalence was significantly associated with weekly incidence of COVID-19 in the general population during the 6-week period over which most testing of individuals without symptoms occurred,” Ms. Sola and colleagues reported. An analysis using additional data from 11 geographic areas demonstrated that this association persisted at a later time point.

The study provides “another window on the question of how likely is it that an asymptomatic child will be carrying coronavirus,” said Susan E. Coffin, MD, MPH, an attending physician for the division of infectious diseases at Children’s Hospital of Philadelphia. However, important related questions remain, said Dr. Coffin, who was not involved with the study.

For one, it is unclear how many children remain asymptomatic in comparison with those who were in a presymptomatic phase at the time of testing. And importantly, “what proportion of these children are infectious?” said Dr. Coffin. “There is some data to suggest that children with asymptomatic infection may be less infectious than children with symptomatic infection.”

It also could be that patients seen at children’s hospitals differ from the general pediatric population. “What does this look like if you do the exact same study in a group of randomly selected children, not children who are queueing up to have a procedure? ... And what do these numbers look like now that stay-at-home orders have been lifted?” Dr. Coffin asked.

Further studies are needed to establish that detection of COVID-19 in the general population is predictive of the prevalence of SARS-CoV-2 infection in asymptomatic children, Dr. Coffin said.

The authors have disclosed no relevant financial relationships.
