Adolescents who undergo metabolic bariatric surgery may require long-term nutrient monitoring and supplementation to prevent nutritional deficiencies, according to investigators.

In a 5-year prospective study, more than a quarter of the participants who underwent vertical sleeve gastrectomy (VSG) developed two or more nutritional deficiencies, reported lead author Stavra A. Xanthakos, MD, of the Cincinnati Children’s Hospital Medical Center, and colleagues.

“Although prevalence of nutritional deficiencies has been estimated largely from adult cohorts, bariatric surgery is an increasingly accepted treatment for severe obesity in youth,” the investigators wrote in Clinical Gastroenterology and Hepatology. “Yet, lower adherence to supplementation and anticipated longer lifespan with altered gastrointestinal physiology may increase risk of adverse nutritional outcomes in these youth.”

Previous research has suggested that teens may be at higher risk for nutritional deficiencies, but these studies were largely retrospective, or when prospective, lacked sufficient long-term follow-up, analysis of comprehensive patient factors, or inclusion of VSG, which is now the predominant technique in the field, the investigators noted.

“Our study is the first to assess comparative nutritional outcomes in adolescents after both VSG and gastric bypass,” they wrote.

The study involved 226 participants aged 13-19 years who underwent either Roux-en-Y gastric bypass (n = 161) or VSG (n = 67) at five tertiary-care centers in the United States during 2007-2012.

Six months after surgery, at 12 months, and on an annual basis thereafter, the investigators gathered clinical data and measured participant serum levels of ferritin; transferrin; albumin; parathyroid hormone; C-reactive protein; and vitamins A, D, B₁, B₁₂, and folate. Analyses also included sex, age, ethnicity, race, household demographics, weight, height, comorbidities, and body mass index (BMI).

The majority of participants were female (75%) and white (72%). At baseline, mean BMI and age were 52.7 kg/m² and 16.5 years, respectively. After 5 years, mean body mass index decreased 23% without a significant difference between procedures.

Generally, nutritional deficiencies occurred earlier and were more common after gastric bypass, although both procedures were ultimately associated with increased risks.

In the gastric bypass group, 59% of participants had two or more nutritional deficiencies at 5 years, and 19% had three more deficiencies, which represented increased rates of fivefold and sixfold, respectively, which the investigators described as “striking.” In the VSG group, 27% of patients had two or more nutritional deficiencies at 5 years; while this fourfold increase was not statistically significant, the investigators suggested that it indicated “a lower, but not negligible, nutritional risk.”

Hypoferritinemia was particularly common in both groups, with rates at year 5 of 71% and 45% among patients who underwent gastric bypass and VSG, respectively.

“Our results now provide critical evidence that VSG does in fact carry significantly lower nutritional risk than Roux-en-Y gastric bypass, but can still worsen iron status,” the investigators wrote.

The investigators also highlighted a nonsignificant increase in the incidence of vitamin B₁₂ deficiency among patients who underwent gastric bypass, with rates increasing from 0.6% at baseline to 11.5% at 5 years.

“Vitamin B₁₂ status likewise worsened disproportionately after [gastric bypass], despite similar trajectories of weight loss after VSG,” the investigators wrote. “This suggests that the differential risk is caused by anatomic and physiological differences between procedures, rather than weight loss alone.”

Beyond surgery type, risk factors for nutritional deficiency included inadequate supplement intake, pregnancy, weight regain, and black race.

“Our findings underscore the importance of long-term nutritional monitoring in adolescents after bariatric surgery and the need to examine impact on health outcomes and quality of life as these youth advance into adulthood, including systematic assessment of anemia and bone health,” the investigators concluded.

The study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases and the National Center for Advancing Translational Sciences of the National Institutes of Health. Dr. Courcoulas reported grant support from Allurion.

Amid the COVID-19 pandemic, defer therapeutic lymphadenectomy for stage III melanoma and opt instead for treatment with checkpoint or BRAF/MEK inhibitors, except when metastatic nodes are threatening vital structures or neoadjuvant therapy is not possible or has already failed, the National Comprehensive Cancer Network said in a new document about managing melanoma during the pandemic.

“The NCCN Melanoma Panel does not consider neoadjuvant therapy as a superior option to surgery followed by systemic adjuvant therapy for stage III melanoma, but available data suggest this is a reasonable resource-conserving option during the COVID-19 outbreak,” according to the panel. Surgery should be performed 8-9 weeks after initiation, said the group, an alliance of physicians from 30 U.S. cancer centers.

Echoing pandemic advice from other medical fields, the group’s melanoma recommendations focused on deferring nonurgent care until after the pandemic passes, and in the meantime limiting patient contact with the medical system and preserving hospital resources by, for instance, using telemedicine and opting for treatment regimens that require fewer trips to the clinic.

In a separate document on nonmelanoma skin cancer (NMSC), the group said that, with the exception of Merkel cell carcinoma, excisions for NMSC – including basal and squamous cell carcinoma, dermatofibrosarcoma protuberans, and rare tumors – should also generally be postponed during the pandemic.

The exception is if there is a risk of metastases within 3 months, but “such estimations of risks ... should be weighed against risks of the patient contracting COVID-19 infection or asymptomatically transmitting COVID-19 to health care workers,” the panel said.

Along the same lines, adjuvant therapy after surgical clearance of localized NMSC “should generally not be undertaken given the multiple visits required,” except for more extensive disease.

For primary cutaneous melanoma , “most time-to-treat studies show no adverse patient outcomes following a 90-day treatment delay, even for thicker [cutaneous melanoma],” the group said, so it recommended delaying wide excisions for melanoma in situ, lesions no thicker than 1 mm (T1) so long as the biopsy removed most of the lesion, and invasive melanomas of any depth if the biopsy had clear margins or only peripheral transection of the in situ component. They said sentinel lymph node biopsy can also be delayed for up to 3 months.

Resections for metastatic stage III-IV disease should also be put on hold unless the patient is symptomatic; systemic treatments should instead be continued. However, “given hospital-intensive resources, the use of talimogene laherparepvec for cutaneous/nodal/in-transit metastasis should be cautiously considered and, if possible, deferred until the COVID-19 crisis abates. A single dose of palliative radiation therapy may be useful for larger/symptomatic metastasis, as appropriate,” the group said.

If resection is still a go, the group noted that adjuvant therapy “has not been shown to improve melanoma-specific survival and should be deferred during the COVID-19 pandemic for patients with [a less than] 50% chance of disease relapse.” Dabrafenib/trametinib is the evidence-based choice if adjuvant treatment is opted for, but “alternative BRAF/MEK inhibitor regimens (encorafenib/binimetinib or vemurafenib/cobimetinib) may be substituted if drug supply is limited” by the pandemic, the group said.

For stage IV melanoma, “single-agent anti-PD-1 [programmed cell death 1] is recommended over combination ipilimumab/nivolumab at present” because there’s less inflammation and possible exacerbation of COVID-19, less need for steroids to counter adverse events, and less need for follow up to check for toxicities.

The group said evidence supports that 400 mg pembrolizumab administered intravenously every 6 weeks would likely be as effective as 200 mg intravenously every 3 weeks and would help keep people out of the hospital.

However, for stage IV melanoma with brain metastasis, there’s a strong rate of response to ipilimumab/nivolumab, so it may still be an option. In that case, “a regimen of ipilimumab 1 mg/kg and nivolumab 3 mg/kg every 3 weeks for four infusions, with subsequent consideration for nivolumab monotherapy, is associated with lower rates of immune-mediated toxicity,” compared with standard dosing.

Regarding potential drug shortages, the group noted that encorafenib/binimetinib or vemurafenib/cobimetinib combinations can be substituted for dabrafenib/trametinib for adjuvant therapy, and single-agent BRAF inhibitors can be used in the event of MEK inhibitor shortages.

In hospice, the group said oral temozolomide is the preferred option for palliative chemotherapy since it would limit resource utilization and contact with the medical system.

The Food and Drug Administration has approved nearly two dozen tests for the novel coronavirus through its Emergency Use Authorization (EUA) policy, according to the Infectious Diseases Society of America (IDSA).

“Based on what we know about influenza, it’s unlikely that all of these tests are going to perform exactly the same way,” said Angela M. Caliendo, MD, executive vice chair of the department of medicine at Brown University in Providence, R.I., at a press briefing. Although these tests are good, no test is perfect, she added.

The development and availability of testing has improved over time, but clinical laboratories still face challenges, said Kimberly E. Hanson, MD, associate professor of internal medicine at University of Utah, Salt Lake City. These challenges include shortages of devices for specimen collection, media, test tubes, and reagents. Although the goal is to test all symptomatic patients, these shortages require laboratories to prioritize health care workers and the sickest patients.
 

Tests are being approved through an abbreviated process

Two types of test, rapid tests and serology tests, are in use. Rapid tests use polymerase chain reactions to detect the virus in a clinical specimen. This type of testing is used to diagnose infection. Serology tests measure antibodies to the virus and are more appropriate for indicating whether a patient has been exposed to the virus.

The declaration of a national emergency enabled the FDA to activate its EUA policy, which allows for quicker approval of tests. Normally, a test must be assessed in the laboratory (such as with a mock specimen or an inactivated virus) and in a clinical study of patients. Under the EUA, clinical assessment is not required for the approval of a test. Consequently, the clinical performance of a test approved under EUA is unknown.

Collecting a specimen of good quality is critical to the quality of the test result, said Dr. Caliendo, the secretary of IDSA’s board of directors. Clinicians and investigators have used nasopharyngeal swabs, sputum, and specimens collected from deep within the lung. “We’re still collecting data to determine which is the best specimen type.” As coronavirus testing expands, particularly to drive-through testing sites, “we may be using people who are not as experienced, and so you might not get as high a quality specimen in that situation,” Dr. Caliendo added.

The timing of the test influences the quality of the result, as well, because the amount of virus is lower at the onset of symptoms than it is later. Another factor that affects the quality of the results is the test’s sensitivity.
 

The time to obtain results varies

The value of having several tests available is that it enables many patients to be tested simultaneously, said Dr. Hanson, a member of IDSA’s board of directors. It also helps to reduce potential problems with the supply of test kits. A test manufacturer, however, may supply parts of the test kit but not the whole kit. This requires the hospital or laboratory to obtain the remaining parts from other suppliers. Furthermore, test manufacturers may need to prioritize areas with high rates of infection or transmission when they ship their tests, which limits testing in other areas.

One reason for the lack of a national plan for testing is that the virus has affected different regions at different times, said Dr. Caliendo. Some tests are more difficult to perform than others, and not all laboratories are equally sophisticated, which can limit testing. It is necessary to test not only symptomatic patients who have been hospitalized, but also symptomatic patients in the community, said Dr. Caliendo. “Ideally, we’re going to need to couple acute diagnostics [testing while people are sick] with serologic testing. Serologic testing is going to be important for us to see who has been infected. That will give us an idea of who is left in our community who is at risk for developing infection.”

How quickly test results are available depends on the type of test and where it is administered. Recently established drive-through clinics can provide results in about 30 minutes. Tests performed in hospitals may take between 1 and 6 hours to yield results. “The issue is, do we have reagents that day?” said Dr. Caliendo. “We have to be careful whom we choose to test, and we screen that in the hospital so that we have enough tests to run as we need them.” But many locations have backlogs. “When you have a backlog of testing, you’re going to wait days, unfortunately, to get a result,” said Dr. Caliendo.

Dr. Caliendo and Dr. Hanson did not report disclosures for this briefing.

Caliendo, MD, executive vice chair of the department of medicine at Brown University in Providence, R.I., at a press briefing. Although these tests are good, no test is perfect, she added.

The development and availability of testing has improved over time, but clinical laboratories still face challenges, said Kimberly E. Hanson, MD, associate professor of internal medicine at University of Utah, Salt Lake City. These challenges include shortages of devices for specimen collection, media, test tubes, and reagents. Although the goal is to test all symptomatic patients, these shortages require laboratories to prioritize health care workers and the sickest patients.
 

Tests are being approved through an abbreviated process

Two types of test, rapid tests and serology tests, are in use. Rapid tests use polymerase chain reactions to detect the virus in a clinical specimen. This type of testing is used to diagnose infection. Serology tests measure antibodies to the virus and are more appropriate for indicating whether a patient has been exposed to the virus.

The declaration of a national emergency enabled the FDA to activate its EUA policy, which allows for quicker approval of tests. Normally, a test must be assessed in the laboratory (such as with a mock specimen or an inactivated virus) and in a clinical study of patients. Under the EUA, clinical assessment is not required for the approval of a test. Consequently, the clinical performance of a test approved under EUA is unknown.

Collecting a specimen of good quality is critical to the quality of the test result, said Dr. Caliendo, the secretary of IDSA’s board of directors. Clinicians and investigators have used nasopharyngeal swabs, sputum, and specimens collected from deep within the lung. “We’re still collecting data to determine which is the best specimen type.” As coronavirus testing expands, particularly to drive-through testing sites, “we may be using people who are not as experienced, and so you might not get as high a quality specimen in that situation,” Dr. Caliendo added.

The timing of the test influences the quality of the result, as well, because the amount of virus is lower at the onset of symptoms than it is later. Another factor that affects the quality of the results is the test’s sensitivity.
 

The time to obtain results varies

The value of having several tests available is that it enables many patients to be tested simultaneously, said Dr. Hanson, a member of IDSA’s board of directors. It also helps to reduce potential problems with the supply of test kits. A test manufacturer, however, may supply parts of the test kit but not the whole kit. This requires the hospital or laboratory to obtain the remaining parts from other suppliers. Furthermore, test manufacturers may need to prioritize areas with high rates of infection or transmission when they ship their tests, which limits testing in other areas.

One reason for the lack of a national plan for testing is that the virus has affected different regions at different times, said Dr. Caliendo. Some tests are more difficult to perform than others, and not all laboratories are equally sophisticated, which can limit testing. It is necessary to test not only symptomatic patients who have been hospitalized, but also symptomatic patients in the community, said Dr. Caliendo. “Ideally, we’re going to need to couple acute diagnostics [testing while people are sick] with serologic testing. Serologic testing is going to be important for us to see who has been infected. That will give us an idea of who is left in our community who is at risk for developing infection.”

How quickly test results are available depends on the type of test and where it is administered. Recently established drive-through clinics can provide results in about 30 minutes. Tests performed in hospitals may take between 1 and 6 hours to yield results. “The issue is, do we have reagents that day?” said Dr. Caliendo. “We have to be careful whom we choose to test, and we screen that in the hospital so that we have enough tests to run as we need them.” But many locations have backlogs. “When you have a backlog of testing, you’re going to wait days, unfortunately, to get a result,” said Dr. Caliendo.

Dr. Caliendo and Dr. Hanson did not report disclosures for this briefing.

A large amount of data suggest that mild or severe cytokine storms, accompanied by high expression of interleukin-6 (IL-6), occur in patients with severe coronavirus disease and can be an important cause of death. Blocking the signal transduction pathway of IL-6 is expected to become a new method for the treatment of patients with severe COVID-19, with the IL-6 inhibitor, tocilizumab (Actemra), poised to become an effective drug for these patients, according to the authors of a review published online in the International Journal of Antimicrobial Agents.

The reviewers from China detailed the metabolic pathways and regulation of cytokine release syndrome, especially with respect to what is known about severe COVID-19, and discussed the results of recent trials with tocilizumab, which is currently used for treatment of CRS in a variety of cancers and other metabolic disorders.

Tocilizumab is a recombinant humanized monoclonal antibody against human IL-6 receptor of immunoglobulin IgG1 subtype and has been approved for the treatment of rheumatoid arthritis and systemic juvenile idiopathic arthritis. The antibody specifically binds soluble- and membrane-bound IL-6 receptors (sIL-6R and mIL-6R) and inhibits sIL-6R– and mIL-6R–mediated signal transduction. It has been shown to be effective in the treatment of severe CRS patients. In 2017, the U.S. Food and Drug Administration approved tocilizumab for the treatment of CRS caused by CAR-T (chimeric antigen receptor T-cell immunotherapy) therapy.

A small clinical trial in China examined the effectiveness of tocilizumab in 21 patients who met the criteria for severe or critical COVID-19, including respiratory failure requiring mechanical ventilation, shock, or admission to the ICU with other organ failure. After a few days of tocilizumab treatment, the body temperatures returned to normal (initially, all 21 patients had fevers), and all other symptoms were significantly improved, according to the authors. A total of 75% (15/20) of the patients reduced their oxygen intake, and 1 patient did not need oxygen. CT scanning showed that 90.5% (19/21) of the patients had absorption of pulmonary lesions, and lab tests showed that the proportion of peripheral blood lymphocytes and C-reactive protein in the patients returned to normal.

The main deficiency of the study was that only the level of IL-6 in peripheral blood before treatment with tocilizumab was reported (mean value, 132.38 ± 278.54 pg/mL), but the level of IL-6 following treatment was not given, according to the reviewers. Serum levels of IL-6 in normal patients are undetectable or very low.

Based upon their analysis of COVID-19’s possible mechanism and the small samples of clinical data available, tocilizumab appeared effective, and “we suggest that it should be used in critically ill COVID-19 patients with significantly elevated IL-6,” the authors stated.

“CRS occurs in a large number of patients with severe COVID-19, which is also an important cause of death. IL-6 is the key molecule of CRS, so IL-6R antagonist tocilizumab may be an important drug to save patients’ lives,” the researchers concluded.

This study was supported by China Mega-Project for Infectious Diseases and the China Mega-Project for Innovative Drugs. The authors reported that they had no conflicts.

Hospitals across the country encountered severe challenges as the first wave of the COVID-19 pandemic swept over them, and they anticipated much worse to come, according to a new report from the Office of Inspector General of the Department of Health and Human Services (HHS).

From March 23 to 27, the OIG interviewed 323 hospitals of several types in 46 states, the District of Columbia, and Puerto Rico. The report it pulled together from these interviews is intended to help HHS manage the crisis, rather than to review its response to the pandemic, the OIG said.

The most significant hospital challenges, the report states, were testing and caring for patients with known or suspected COVID-19 and protecting staff members. In addition, the hospitals faced challenges in maintaining or expanding their capacities to treat COVID-19 patients and ensuring the adequacy of basic supplies.

The critical shortages of ventilators, personal protective equipment (PPE), and test kits in hospitals have been widely reported by the media. But the OIG report also focused on some areas that have received less press attention.

To begin with, the shortage of tests has not only slowed the national response to the pandemic, but has had a major impact on inpatient care, according to the report’s authors. The limited number of test kits means that only symptomatic staff members and patients can be tested; in some hospitals, there aren’t even enough tests for that, and some facilities subdivided the test kits they had, the report states.

Moreover, the test results often took 7 days or more to come back from commercial or government labs, the report states. In the meantime, symptomatic patients were presumed to have the coronavirus. While awaiting the results, they had to stay in the hospital, using beds and requiring staff who could otherwise have been assigned to other patients.

The doctors and nurse who cared for these presumptive COVID-19 patients also had to take time suiting up in PPE before seeing them; much of that scarce PPE was wasted on those who were later found not to have the illness.

As one administrator explained to OIG, “Sitting with 60 patients with presumed positives in our hospital isn’t healthy for anybody.”

Delayed test results also reduced hospitals’ ability to provide care by sidelining clinicians who reported COVID-19 symptoms. In one hospital, 20% to 25% of staff were determined to be presumptively positive for COVID-19. As a result of their tests not being analyzed promptly, these doctors and nurses were prevented from providing clinical services for longer than necessary.
 

Supply Shortages

The report also described some factors contributing to mask shortages. Because of the fear factor, for example, all staff members in one hospital were wearing masks, instead of just those in designated areas. An administrator said the hospital was using 2,000 masks a day, 10 times the number before the COVID-19 crisis.

Another hospital received 2,300 N95 masks from a state reserve, but they were unusable because the elastic bands had dry-rotted.

Meanwhile, some vendors were profiteering. Masks that used to cost 50 cents now sold for $6 each, one administrator said.

To combat the supply chain disruptions, some facilities were buying PPE from nontraditional sources such as online retailers, home supply stores, paint stores, autobody supply shops, and beauty salons. Other hospitals were using non–medical-grade PPE such as construction masks and handmade masks and gowns.

Other hospitals reported they were conserving and reusing PPE to stretch their supplies. In some cases, they had even changed policies to reduce the extent and frequency of patient interactions with clinicians so the latter would have to change their gear less often.

Shortages of other critical supplies and materials were also reported. Hospitals were running out of supplies that supported patient rooms, such as IV poles, medical gas, linens, toilet paper, and food.

Hospitals across the country were also expecting or experiencing a shortage of ventilators, although none said any patients had been denied access to them. Some institutions were adapting anesthesia machines and single-use emergency transport ventilators.

Also concerning to hospitals was the shortage of intensive-care specialists and nurses to operate the ventilators and care for critically ill patients. Some facilities were training anesthesiologists, hospitalists, and other nonintensivists on how to use the lifesaving equipment.

Meanwhile, patients with COVID-19 symptoms were continuing to show up in droves at emergency departments. Hospitals were concerned about potential shortages of ICU beds, negative-pressure rooms, and isolation units. Given limited bed availability, some administrators said, it was getting hard to separate COVID-19 from non–COVID-19 patients.
 

What Hospitals Want

As the COVID-19 crisis continues to mount, many hospitals are facing financial emergencies as well, the report noted.

“Hospitals described increasing costs and decreasing revenues as a threat to their financial viability. Hospitals reported that ceasing elective procedures and other services decreased revenues at the same time that their costs have increased as they prepare for a potential surge of patients. Many hospitals reported that their cash reserves were quickly depleting, which could disrupt ongoing hospital operations,” the authors write.

This report was conducted a few days before the passage of the CURES Act, which earmarked $100 billion for hospitals on the frontline of the crisis. As a recent analysis of financial hospital data revealed, however, even with the 20% bump in Medicare payments for COVID-19 care that this cash infusion represents, many hospitals will face a cash-flow crunch within 60 to 90 days, as reported by Medscape Medical News.

Besides higher Medicare payments, the OIG report said, hospitals wanted the government to drop the 14-day waiting period for reimbursement and to offer them loans and grants.

Hospitals also want federal and state governments to relax regulations on professional licensing of, and business relationships with, doctors and other clinicians. They’d like the government to:

• Let them reassign licensed professionals within their hospitals and across healthcare networks
• Provide flexibility with respect to licensed professionals practicing across state lines
• Provide relief from regulations that may restrict using contracted staff or physicians based on business relationships

The characteristic COVID-19 symptoms of cough, fever, and shortness of breath are less common in children than adults, according to the Centers for Disease and Prevention Control.

Among pediatric patients younger than 18 years in the United States, 73% had at least one of the trio of symptoms, compared with 93% of adults aged 18-64, noted Lucy A. McNamara, PhD, and the CDC’s COVID-19 response team, based on a preliminary analysis of the 149,082 cases reported as of April 2.

By a small margin, fever – present in 58% of pediatric patients – was the most common sign or symptom of COVID-19, compared with cough at 54% and shortness of breath in 13%. In adults, cough (81%) was seen most often, followed by fever (71%) and shortness of breath (43%), the investigators reported in the MMWR.

In both children and adults, headache and myalgia were more common than shortness of breath, as was sore throat in children, the team added.

“These findings are largely consistent with a report on pediatric COVID-19 patients aged <16 years in China, which found that only 41.5% of pediatric patients had fever [and] 48.5% had cough,” they wrote.

The CDC analysis of pediatric patients was limited by its small sample size, with data on signs and symptoms available for only 11% (291) of the 2,572 children known to have COVID-19 as of April 2. The adult population included 10,944 individuals, who represented 9.6% of the 113,985 U.S. patients aged 18-65, the response team said.

“As the number of COVID-19 cases continues to increase in many parts of the United States, it will be important to adapt COVID-19 surveillance strategies to maintain collection of critical case information without overburdening jurisdiction health departments,” they said.

Among pediatric patients younger than 18 years in the United States, 73% had at least one of the trio of symptoms, compared with 93% of adults aged 18-64, noted Lucy A. McNamara, PhD, and the CDC’s COVID-19 response team, based on a preliminary analysis of the 149,082 cases reported as of April 2.

By a small margin, fever – present in 58% of pediatric patients – was the most common sign or symptom of COVID-19, compared with cough at 54% and shortness of breath in 13%. In adults, cough (81%) was seen most often, followed by fever (71%) and shortness of breath (43%), the investigators reported in the MMWR.

In both children and adults, headache and myalgia were more common than shortness of breath, as was sore throat in children, the team added.

“These findings are largely consistent with a report on pediatric COVID-19 patients aged <16 years in China, which found that only 41.5% of pediatric patients had fever [and] 48.5% had cough,” they wrote.

The CDC analysis of pediatric patients was limited by its small sample size, with data on signs and symptoms available for only 11% (291) of the 2,572 children known to have COVID-19 as of April 2. The adult population included 10,944 individuals, who represented 9.6% of the 113,985 U.S. patients aged 18-65, the response team said.

“As the number of COVID-19 cases continues to increase in many parts of the United States, it will be important to adapt COVID-19 surveillance strategies to maintain collection of critical case information without overburdening jurisdiction health departments,” they said.

As clinicians grapple with the COVID-19 pandemic, the American Academy of Pediatrics has released interim guidance on managing infants born of infected mothers.

“Pediatric cases of COVID-19 are so far reported as less severe than disease occurring among older individuals,” Karen M. Puopolo, MD, PhD, a neonatologist and chief of the section on newborn pediatrics at Pennsylvania Hospital, Philadelphia, and coauthors wrote in the 18-page document, which was released on April 2, 2020, along with an abbreviated “Frequently Asked Questions” summary. However, one study of children with COVID-19 in China found that 12% of confirmed cases occurred among 731 infants aged less than 1 year; 24% of those 86 infants “suffered severe or critical illness” (Pediatrics. 2020 March. doi: 10.1542/peds.2020-0702). There were no deaths reported among these infants. Other case reports have documented COVID-19 in children aged as young as 2 days.

The document, which was assembled by members of the AAP Committee on Fetus and Newborn, Section on Neonatal Perinatal Medicine, and Committee on Infectious Diseases, pointed out that “considerable uncertainty” exists about the possibility for vertical transmission of SARS-CoV-2 from infected pregnant women to their newborns. “Evidence-based guidelines for managing antenatal, intrapartum, and neonatal care around COVID-19 would require an understanding of whether the virus can be transmitted transplacentally; a determination of which maternal body fluids may be infectious; and data of adequate statistical power that describe which maternal, intrapartum, and neonatal factors influence perinatal transmission,” according to the document. “In the midst of the pandemic these data do not exist, with only limited information currently available to address these issues.”

Based on the best available evidence, the guidance authors recommend that clinicians temporarily separate newborns from affected mothers to minimize the risk of postnatal infant infection from maternal respiratory secretions. “Newborns should be bathed as soon as reasonably possible after birth to remove virus potentially present on skin surfaces,” they wrote. “Clinical staff should use airborne, droplet, and contact precautions until newborn virologic status is known to be negative by SARS-CoV-2 [polymerase chain reaction] testing.”

While SARS-CoV-2 has not been detected in breast milk to date, the authors noted that mothers with COVID-19 can express breast milk to be fed to their infants by uninfected caregivers until specific maternal criteria are met. In addition, infants born to mothers with COVID-19 should be tested for SARS-CoV-2 at 24 hours and, if still in the birth facility, at 48 hours after birth. Centers with limited resources for testing may make individual risk/benefit decisions regarding testing.

For infants infected with SARS-CoV-2 but have no symptoms of the disease, they “may be discharged home on a case-by-case basis with appropriate precautions and plans for frequent outpatient follow-up contacts (either by phone, telemedicine, or in office) through 14 days after birth,” according to the document.

If both infant and mother are discharged from the hospital and the mother still has COVID-19 symptoms, she should maintain at least 6 feet of distance from the baby; if she is in closer proximity she should use a mask and hand hygiene. The mother can stop such precautions until she is afebrile without the use of antipyretics for at least 72 hours, and it is at least 7 days since her symptoms first occurred.

In cases where infants require ongoing neonatal intensive care, mothers infected with COVID-19 should not visit their newborn until she is afebrile without the use of antipyretics for at least 72 hours, her respiratory symptoms are improved, and she has negative results of a molecular assay for detection of SARS-CoV-2 from at least two consecutive nasopharyngeal swab specimens collected at least 24 hours apart.

I know that the world has gone upside down. It’s a nightmare, and people are filled with fear, and death is everywhere. In my little bubble of a world, however, I’ve been doing well.

I can’t lose my job, because I am my job. I’m a solo practitioner and have been for more than a decade. The restrictions to stay at home have not affected me, because I have a home office. Besides, I’m an introvert and see myself as a bit of a recluse, so the social distancing hasn’t been stressful. Conducting appointments by phone rather than face to face hasn’t undermined my work, since I can do everything that I do in my office over the phone. But I do it now in sweats and at my desk in my bedroom more often than not. I am prepared for a decrease in income as people lose their jobs, but that hasn’t happened yet. There are still people out there who are very motivated to come off their medications holistically. No rest for the wicked, as the saying goes.

On an emotional level, I feel calm because I’m not attached to material things, though I like them when they’re here. My children and friends have remained healthy, so I am grateful for that. On a spiritual level, I’m prepared to live or die. I feel grounded in my belief that life goes on one way or another, and I trust in God to direct me wherever I need to go. Socially, I’ve been forced to be less lazy and cook more at home. As a result: less salt, MSG, and greasy food. I’ve spent a lot less on restaurants this past month and am eating less since I have to eat whatever I cook.

Can a person be more pandemic proof? I was joking with a friend about how pandemic-friendly my lifestyle is: spiritually, mentally, emotionally, physically, and socially. Oh, did I forget to mention the year supply of supplements in my office closet? They were for my patients, but those whole food green and red powders may come in handy, just in case.

So, that is how things are going for me. Please don’t hate me for not freaking out. When I read the news, I feel very sad for people who are suffering. I get angry at the politicians who can’t get their egos out of the way. But, I look at the sunshine outside my window, and I feel grateful that, at least in my case, I am not adding to the burden of suffering in the world. Not yet, anyway. I will keep trying to do the little bit that I do to help others for as long as I can.

Eventually this strange Twilight Zone world of coronavirus will end and life will return to normal.

But obviously it won’t be the same, and like everyone else I wonder what will be different.

Telemedicine is one obvious change in my world, though I don’t know how much yet (granted, no one else does, either). I’m seeing a handful of people that way, limited to established patients, where we’re discussing chronic issues or reviewing recent test results.

If I have to see a new patient or an established one with an urgent issue, I’m still willing to meet them at my office (wearing masks and washing hands frequently). In neurology, a lot still depends on a decent exam. It’s pretty hard to check reflexes, sensory modalities, and muscle tone over the phone. If you think a malpractice attorney is going to give you a pass because you missed something by not examining a patient because of coronavirus ... think again.

I’m not sure how the whole telemedicine thing will play out after the dust settles, at least not at my little practice. I’m currently seeing patients by FaceTime and Skype, neither of which is considered HIPAA compliant. The requirement has been waived during the crisis to make sure people can still see doctors, but I don’t see it lasting beyond that. Privacy will always be a central concern in medicine.

When they declare the pandemic over and say I can’t use FaceTime or Skype anymore, that will likely end my use of such. While there are HIPAA-compliant telemedicine services out there, in a small practice I don’t have the time or money to invest in them.

I also wonder how outcomes will change. I suspect the research-minded will be analyzing 2019 vs. 2020 data for years to come, trying to see if a sudden increase in telemedicine led to better or worse clinical outcomes. I’ll be curious to see what they find and how it breaks down by disease and specialty.

How will work change? Right now my staff of three (including me) are all working separately from home, handling phone calls as if it were another office day. In today’s era that’s easy to set up, and we’re used to the drill from when I’m out of town.

Maybe in the future, on lighter days, I’ll do this more often, and have my staff work from home (on typically busy days I’ll still need them to check patients in and out, fax things, file charts, and do all the other things they do to keep the practice running). The marked decrease in air pollution is certainly noticeable and good for all. When the year is over I’d like to see how non-coronavirus respiratory issues changed between 2019 and 2020.

Other businesses will be looking at that, too, with an increase in telecommuting. Why pay for a large office space when a lot can be done over the Internet? It saves rent, gas, and driving time. How it will affect us, as a socially-dependent species, I have no idea.

It’s the same with grocery delivery. While most of us will likely continue to shop at stores, many will stay with the ease of delivery services after this. It may cost more, but it certainly saves time.

There will be social changes, although how long they’ll last is anyone’s guess. Grocery baggers, stockers, and delivery staff, often seen as lower-level occupations, are now considered part of critical infrastructure in keeping people supplied with food and other necessities, as well as preventing fights from breaking out in the toilet paper and hand-sanitizer aisles.

I’d like to think that, in a country divided, the need to work together will help bring people of different opinions together again, but from the way things look I don’t see that happening, which is sad because viruses don’t discriminate, so we shouldn’t either in fighting them.

Like with other challenges that we face, big and little, I can only hope that we’ll learn something from this and have a better world after it’s over. Only time will tell.

Grocery baggers, stockers, and delivery staff, often seen as lower-level occupations, are now considered part of critical infrastructure in keeping people supplied with food and other necessities, as well as preventing fights from breaking out in the toilet paper and hand-sanitizer aisles.

I’d like to think that, in a country divided, the need to work together will help bring people of different opinions together again, but from the way things look I don’t see that happening, which is sad because viruses don’t discriminate, so we shouldn’t either in fighting them.

Like with other challenges that we face, big and little, I can only hope that we’ll learn something from this and have a better world after it’s over. Only time will tell.

At issue is the standard use of ventilators for a virus whose presentation has not followed the standard for ARDS, but is looking more like high-altitude pulmonary edema (HAPE) in some patients.

In a letter to the editor published in the American Journal of Respiratory and Critical Care Medicine on March 30, and in an editorial accepted for publication in Intensive Care Medicine, Luciano Gattinoni, MD, of the Medical University of Göttingen in Germany and colleagues make the case that protocol-driven ventilator use for patients with COVID-19 could be doing more harm than good.

Dr. Gattinoni noted that COVID-19 patients in ICUs in northern Italy had an atypical ARDS presentation with severe hypoxemia and well-preserved lung gas volume. He and colleagues suggested that instead of high positive end-expiratory pressure (PEEP), physicians should consider the lowest possible PEEP and gentle ventilation–practicing patience to “buy time with minimum additional damage.”

Similar observations were made by Cameron Kyle-Sidell, MD, a critical care physician working in New York City, who has been speaking out about this issue on Twitter and who shared his own experiences in this video interview with WebMD chief medical officer John Whyte, MD.

The bottom line, as Dr. Kyle-Sidell and Dr. Gattinoni agree, is that protocol-driven ventilator use may be causing lung injury in COVID-19 patients.
 

Consider disease phenotype

In the editorial, Dr. Gattinoni and colleagues explained further that ventilator settings should be based on physiological findings – with different respiratory treatment based on disease phenotype rather than using standard protocols.

‘“This, of course, is a conceptual model, but based on the observations we have this far, I don’t know of any model which is better,” he said in an interview.

Anecdotal evidence has increasingly demonstrated that this proposed physiological approach is associated with much lower mortality rates among COVID-19 patients, he said.

While not willing to name the hospitals at this time, he said that one center in Europe has had a 0% mortality rate among COVID-19 patients in the ICU when using this approach, compared with a 60% mortality rate at a nearby hospital using a protocol-driven approach.

In his editorial, Dr. Gattinoni disputed the recently published recommendation from the Surviving Sepsis Campaign that “mechanically ventilated patients with COVID-19 should be managed similarly to other patients with acute respiratory failure in the ICU.”

“Yet, COVID-19 pneumonia, despite falling in most of the circumstances under the Berlin definition of ARDS, is a specific disease, whose distinctive features are severe hypoxemia often associated with near normal respiratory system compliance,” Dr. Gattinoni and colleagues wrote, noting that this was true for more than half of the 150 patients he and his colleagues had assessed, and that several other colleagues in northern Italy reported similar findings. “This remarkable combination is almost never seen in severe ARDS.”

Dr. Gattinoni and colleagues hypothesized that COVID-19 patterns at patient presentation depend on interaction between three sets of factors: 1) disease severity, host response, physiological reserve and comorbidities; 2) ventilatory responsiveness of the patient to hypoxemia; and 3) time elapsed between disease onset and hospitalization.

They identified two primary phenotypes based on the interaction of these factors: Type L, characterized by low elastance, low ventilator perfusion ratio, low lung weight, and low recruitability; and Type H, characterized by high elastance, high right-to-left shunt, high lung weight, and high recruitability.

“Given this conceptual model, it follows that the respiratory treatment offered to Type L and Type H patients must be different,” Dr. Gattinoni said.

Patients may transition between phenotypes as their disease evolves. “If you start with the wrong protocol, at the end they become similar,” he said.

Rather, it is important to identify the phenotype at presentation to understand the pathophysiology and treat accordingly, he advised.

The phenotypes are best identified by CT scan, but signs implicit in each of the phenotypes, including respiratory system elastance and recruitability, can be used as surrogates if CT is unavailable, he noted.

“This is a kind of disease in which you don’t have to follow the protocol – you have to follow the physiology,” he said. “Unfortunately, many, many doctors around the world cannot think outside the protocol.”

In his interview with Dr. Whyte, Dr. Kyle-Sidell stressed that doctors must begin to consider other approaches. “We are desperate now, in the sense that everything we are doing does not seem to be working,” Dr. Kyle-Sidell said, noting that the first step toward improving outcomes is admitting that “this is something new.”

“I think it all starts from there, and I think we have the kind of scientific technology and the human capital in this country to solve this or at least have a very good shot at it,” he said.
 

Proposed treatment model

Dr. Gattinoni and his colleagues offered a proposed treatment model based on their conceptualization:

• Reverse hypoxemia through an increase in FiO₂ to a level at which the Type L patient responds well, particularly for Type L patients who are not experiencing dyspnea.
• In Type L patients with dyspnea, try noninvasive options such as high-flow nasal cannula, continuous positive airway pressure, or noninvasive ventilation, and be sure to measure inspiratory esophageal pressure using esophageal manometry or surrogate measures. In intubated patients, determine P0.1 and P occlusion. High PEEP may decrease pleural pressure swings “and stop the vicious cycle that exacerbates lung injury,” but may be associated with high failure rates and delayed intubation.
• Intubate as soon as possible for esophageal pressure swings that increase from 5-10 cm H₂O to above 15 cm H₂O, which marks a transition from Type L to Type H phenotype and represents the level at which lung injury risk increases.
• For intubated and deeply sedated Type L patients who are hypercapnic, ventilate with volumes greater than 6 mL/kg up to 8-9 mL/kg as this high compliance results in tolerable strain without risk of ventilator-associated lung injury. Prone positioning should be used only as a rescue maneuver. Reduce PEEP to 8-10 cm H₂O, given that the recruitability is low and the risk of hemodynamic failure increases at higher levels. Early intubation may avert the transition to Type H phenotype.
• Treat Type H phenotype like severe ARDS, including with higher PEEP if compatible with hemodynamics, and with prone positioning and extracorporeal support.
