RESUMO
OBJECTIVES: To describe trends in critical illness from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children over the course of the COVID-19 pandemic. We hypothesized that PICU admission rates were higher in the Omicron period compared with the original outbreak but that fewer patients needed endotracheal intubation. DESIGN: Retrospective cohort study. SETTING: This study took place in nine U.S. PICUs over 3 weeks in January 2022 (Omicron period) compared with 3 weeks in March 2020 (original period). PATIENTS: Patients less than or equal to 21 years old who screened positive for SARS-CoV-2 infection by polymerase chain reaction or hospital-based rapid antigen test and were admitted to a PICU or intermediate care unit were included. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 267 patients (239 Omicron and 28 original) were reviewed. Forty-five patients in the Omicron cohort had incidental SARS-CoV-2 and were excluded from analysis. The Omicron cohort patients were younger compared with the original cohort patients (median [interquartile range], 6 yr [1.3-13.3 yr] vs 14 yr [8.3-17.3 yr]; p = 0.001). The Omicron period, compared with the original period, was associated with an average increase in COVID-19-related PICU admissions of 13 patients per institution (95% CI, 6-36; p = 0.008), which represents a seven-fold increase in the absolute number admissions. We failed to identify an association between cohort period (Omicron vs original) and odds of intubation (odds ratio, 0.7; 95% CI, 0.3-1.7). However, we cannot exclude the possibility of up to 70% reduction in intubation. CONCLUSIONS: COVID-19-related PICU admissions were seven times higher in the Omicron wave compared with the original outbreak. We could not exclude the possibility of up to 70% reduction in use of intubation in the Omicron versus original epoch, which may represent differences in PICU/hospital admission policy in the later period, or pattern of disease, or possibly the impact of vaccination.

ABSTRACT: The rapid spread of COVID-19 brought forth a rapid increase in hospitalization rates, requiring changes in hospital use and medical personnel structure. Physician assistants (PAs) and NPs in pediatric critical care were cross-trained and redeployed to our pediatric biocontainment unit to address the clinician strain in providing high-quality patient care during these unprecedented times. This manuscript discusses the effectiveness of using these clinicians while recognizing the challenges of managing a novel virus in a new unit.

OBJECTIVES: The COVID-19 pandemic has brought new challenges to pediatric transport programs. The aims of this study were to describe the transport of pediatric patients with confirmed COVID-19 and to review the operational challenges that our transport system encountered. METHODS: A retrospective descriptive study was performed to review all COVID-19 pediatric transport performed over a 6-month period during the initial pandemic surge in 2020. Pediatric patients with a known positive SARS-CoV-2 polymerase chain reaction test at the time of transport were included. Patients' hospital records, including their transport record, were reviewed for demographics, diagnoses, transport interventions and complications, and admission disposition. Descriptive statistics were used to describe the patient cohort. RESULTS: Of the 883 transports performed between April and October 2020, 146 (16%) tested positive for COVID-19 during the initial surge in our geographical area. Patient acuity was diverse with 40% of children having a chronic complex medical condition. More than 25% of children required aerosol-generating procedures during transport. The most common medical diagnosis was respiratory compromise, and the most common surgical diagnosis was appendicitis. No adverse events occurred during transports, and no transport team members contracted COVID-19 because of workplace exposure. Transport program operational challenges ranged from rapidly changing system logistics/policies to educational and utilization of proper personal protective equipment. CONCLUSIONS: Children with COVID-19 can be transported safely with adaption of transport program procedures. Change management and team stress should be anticipated and can be addressed with repeated education and messaging.

BACKGROUND: An understanding of the clinical characteristics of children with coronavirus disease 2019 in diverse communities is needed to optimize the response of healthcare providers during this pandemic. METHODS: We performed a retrospective review of all children presenting to the Texas Children's Hospital system with testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from March 10, 2020, through June 28, 2020. Demographics were recorded for all patients undergoing testing and clinical characteristics and outcomes were recorded for children with positive tests. RESULTS: Of 16 554 unique patients ≤ 21 years of age who were tested for SARS-CoV-2, 1215 (7.3%) patients tested positive. Infants under 1 year of age and patients aged 18-21 years had the highest percent of positive tests at 9.9% (230/2329) and 10.7% (79/739), respectively. Hispanic children accounted for 66% (802/1215) of positive tests, though they only represented 42.1% (6972/16 554) of all children tested for SARS-CoV-2. Of the 1215 children with a positive test, 55.7% had fever, 40.9% had cough, 39.8% had congestion or rhinorrhea, 21.9% had gastrointestinal complaints, and 15.9% were asymptomatic. Only 97 (8%) patients were hospitalized (of which 68% were Hispanic). Most of the hospitalized patients had underlying medical conditions (62/97, 63.9%), including obesity. Thirty-one hospitalized patients (31/97, 32%) required respiratory support and 9 patients (9/97, 9.3%) received SARS-CoV-2 antiviral therapy. Two patients died. CONCLUSIONS: A relatively high percentage of Hispanic children tested positive for SARS-CoV-2 and were hospitalized. Most of the children with detection of SARS-CoV-2 had uncomplicated illness courses; some children were critically ill; and 2 patients died.

We describe the clinical course of 57 children with coronavirus disease 2019 (COVID-19) cared for through a single hospital system. Most children were mildly symptomatic, and only a few patients with underlying medical conditions required hospitalization. Systemwide patient evaluation processes allowed for prompt identification and management of patients with COVID-19.

Simian virus 40 (SV40) is a DNA tumor virus known to induce cancers in laboratory animals. There are numerous reports of the detection of SV40 DNA and/or proteins in human malignancies of the same types as those induced by SV40 in animals, including brain cancers. However, known exposure to the virus has not yet been linked directly to cancer development in a specific individual. Here we describe the detection of SV40 sequences in the meningioma of a laboratory researcher who had a probable direct exposure to SV40 and subsequently developed a tumor positive for viral DNA sequences indistinguishable from those of the laboratory source. This case suggests a link between viral exposure and tumor development.

BACKGROUND: Many studies have reported the presence of simian virus 40 (SV40) deoxyribonucleic acid (DNA) or protein in human brain tumors and bone cancers, malignant mesothelioma, and non-Hodgkin's lymphoma. However, the small samples and lack of control groups in some reports have made it difficult to assess their reliability. METHODS: Studies were included in this analysis if they met the following criteria: original studies of patients with primary brain tumors and bone cancers, malignant mesothelioma, or non-Hodgkin's lymphoma; the investigation of SV40 was performed on primary cancer specimens; the analysis included a control group; and the same technique was used for cases and controls. Included reports were published from 1975 to 2002. RESULTS: Thirteen studies fulfilled the criteria for the investigation of primary brain cancers (661 tumors and 482 control samples). Specimens from patients with brain tumors were almost four times more likely to have evidence of SV40 infection than were those from controls (odds ratio [OR] = 3.9; 95% confidence interval [CI]: 2.6 to 5.8). The association was even stronger for mesothelioma (OR = 17; 95% CI: 10 to 28; based on 15 studies with 528 mesothelioma samples and 468 control samples) and for bone cancer (OR = 25; 95% CI: 6.8 to 88; based on four studies with 303 cancers and 121 control samples). SV40 DNA was also more frequent in samples from patients with non-Hodgkin's lymphoma (OR = 5.4; 95% CI: 3.1 to 9.3; based on three studies with 301 cases and 578 control samples) than from controls. CONCLUSION: These results establish that SV40 is associated significantly with brain tumors, bone cancers, malignant mesothelioma, and non-Hodgkin's lymphoma. Studies are needed to assess current prevalence of SV40 infections.

Viral strain differences influence the oncogenic potential of polyomavirus simian virus 40 (SV40). We hypothesized that viral strain differences might also affect vertical transmission of SV40 in susceptible hosts. Pregnant Syrian golden hamsters were inoculated intraperitoneally with 10(7) plaque-forming units of SV40 and offspring were sacrificed post-delivery (1-21 days, 6 months). Organ extracts were analyzed for SV40 DNA by polymerase chain reaction assay. Transmission of SV40 from mother to offspring was detected in over half of litters. Most placentas were virus-positive. Mothers inoculated with SV40 strains containing complex regulatory regions transmitted virus more frequently than those infected with simple enhancer viruses (p<0.001). Virus was detected more often in progeny brain than in spleen (p<0.05). Several progeny were virus-positive at 6 months of age, suggesting viral persistence. Maternal animals retained virus in several tissues through day 21 and developed T-antigen antibodies. These results indicate that SV40 replicates in hamsters, vertical transmission of SV40 can occur, and the viral regulatory region influences transmission.
