Visitor restriction during the COVID-19 pandemic did not impact rates of Staphylococcus aureus colonization in the NICU patients.

OBJECTIVES: In our neonatal intensive care unit (NICU), patients are screened for colonization with Staphylococcus aureus (S. aureus) and decolonized if positive. During the COVID-19 pandemic, our NICU significantly limited its visitor policy. We assessed for a difference between S. aureus colonization rates before and after the visitor policy change, which coincided with the exponential rise of COVID-19 cases in New York City (NYC). METHODS: We calculated rates of newly S. aureus colonized NICU patients during January to June 2020 and compared rates pre- and post-implementation of the new visitor policy. Additionally, we obtained the weekly incidence of COVID-19 in NYC and assessed for a correlation between COVID-19 rates and S. aureus colonization. RESULTS: The number of newly colonized patients per thousand patient days was 4.65 pre- and 3.95 post-implementation of the new visitor policy. The difference was not statistically significant (p=0.66). Furthermore, there was no correlation between the incidence of COVID-19 in NYC and the rates of S. aureus colonization in our NICU (R2=0.02). CONCLUSIONS: Our results suggest that limiting visitation of patients is not associated with a decrease in S. aureus colonization rate. Hospital unit leaders may need to focus on other strategies in order to reduce colonization.

Characteristics of Cardiac Abnormalities in Pediatric Patients With Acute COVID-19.

Introduction Coronavirus disease 2019 (COVID-19) is known to cause cardiac abnormalities in adults. Cardiac abnormalities are well-described in multisystem inflammatory syndrome in children, but effects in children with acute COVID-19 are less understood. In this multicenter study, we assessed the cardiac effects of acute COVID-19 among hospitalized children (<21 years) admitted to three large healthcare systems in New York City. Methods We performed a retrospective observational study. We examined electrocardiograms, echocardiograms, troponin, or B-type natriuretic peptides. Results Of 317 admitted patients, 131 (41%) underwent cardiac testing with 56 (43%) demonstrating cardiac abnormalities. Electrocardiogram abnormalities were the most common (46/117 patients (39%)), including repolarization abnormalities and QT prolongation. Elevated troponin occurred in 14/77 (18%) patients and B-type natriuretic peptide in 8/39 (21%) patients. Ventricular dysfunction was identified in 5/27 (19%) patients with an echocardiogram, all of whom had elevated troponin. Ventricular dysfunction resolved by first outpatient follow-up. Conclusion Electrocardiogram and troponin can assist clinicians in identifying children at risk for cardiac injury in acute COVID-19.

Developmental screening of full-term infants at 16 to 18 months of age after in-utero exposure to maternal SARS-CoV-2 infection

Objective To screen for neurodevelopmental delays in a cohort of full-term infants born to mothers with SARS-CoV-2. Study design This was a prospective, descriptive cohort study of full-term infants born to mothers with SARS-CoV-2 during pregnancy. Subjects underwent neurodevelopmental screening using the Ages and Stages Questionnaires®-Third Edition (ASQ®-3) at 16 to 18 months age. Results Of 51 subjects, twelve (24%) were below cutoff, and twenty-seven (53%) were either below or close to the cutoff in at least one developmental domain. Communication (29%), fine motor (31%), and problem-solving (24%) were the most affected domains. There were no differences in outcomes between infants born to asymptomatic and mildly symptomatic mothers. Conclusion We observed increased risk of neurodevelopmental delays during screening of infants born at full-term to mothers with SARS-CoV-2 at 16 to 18 months age. These results highlight the urgent need for follow-up studies of infants born to mothers with SARS-CoV-2.

Mother to Newborn Transmission of SARS-CoV-2 Infection: Evolution of Evidence in 1.5 Years of COVID-19 Pandemic.

Coronavirus disease 2019 (COVID-19) pandemic caused significant mortality and morbidity in people of all age groups worldwide. Given the uncertainty regarding the mode of transmission and potential effects of COVID-19 on pregnant mothers and their newborns, guidelines for taking care of maternal-newborn dyads have evolved tremendously since the pandemic began. There has been an enormous influx of published materials regarding the outcomes of mothers and newborns. Still, multiple knowledge gaps regarding comprehensive information about risk to the mothers and newborns exist, which need to be addressed. Current evidence suggests that mothers with symptomatic COVID-19 infection are at increased risk of severe illness during pregnancy, with a higher need for respiratory support and premature deliveries. Neonates born to mothers with COVID-19 are at increased risk of needing intensive care; however, most newborns do well after birth. As new mutant variants arise, we need to be cautious while proactively understanding any new evolving patterns. All leading health authorities strongly recommend COVID-19 vaccination before or during pregnancy to reduce the risk of maternal morbidities and benefit from passing antibodies to newborns prenatally and via breastmilk. Additionally, there are racial, ethnic, and socioeconomic disparities in outcomes and vaccination coverage for pregnant women. This article summarizes the rapidly evolving evidence for the last 1.5 years and aims to help health care professionals care for mothers with COVID-19 and their newborns. KEY POINTS: · COVID-19 in pregnancy can cause perinatal morbidities.. · Breastfeeding and breast milk are safe for newborns.. · COVID-19 vaccination reduces the risk for morbidities..

Characterization and Outcomes of Hospitalized Children With Coronavirus Disease 2019: A Report From a Multicenter, Viral Infection and Respiratory Illness Universal Study (Coronavirus Disease 2019) Registry.

OBJECTIVES: Multicenter data on the characteristics and outcomes of children hospitalized with coronavirus disease 2019 are limited. Our objective was to describe the characteristics, ICU admissions, and outcomes among children hospitalized with coronavirus disease 2019 using Society of Critical Care Medicine Discovery Viral Infection and Respiratory Illness Universal Study: Coronavirus Disease 2019 registry. DESIGN: Retrospective study. SETTING: Society of Critical Care Medicine Viral Infection and Respiratory Illness Universal Study (Coronavirus Disease 2019) registry. PATIENTS: Children (< 18 yr) hospitalized with coronavirus disease 2019 at participating hospitals from February 2020 to January 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary outcome was ICU admission. Secondary outcomes included hospital and ICU duration of stay and ICU, hospital, and 28-day mortality. A total of 874 children with coronavirus disease 2019 were reported to Viral Infection and Respiratory Illness Universal Study registry from 51 participating centers, majority in the United States. Median age was 8 years (interquartile range, 1.25-14 yr) with a male:female ratio of 1:2. A majority were non-Hispanic (492/874; 62.9%). Median body mass index (n = 817) was 19.4 kg/m2 (16-25.8 kg/m2), with 110 (13.4%) overweight and 300 (36.6%) obese. A majority (67%) presented with fever, and 43.2% had comorbidities. A total of 238 of 838 (28.2%) met the Centers for Disease Control and Prevention criteria for multisystem inflammatory syndrome in children, and 404 of 874 (46.2%) were admitted to the ICU. In multivariate logistic regression, age, fever, multisystem inflammatory syndrome in children, and pre-existing seizure disorder were independently associated with a greater odds of ICU admission. Hospital mortality was 16 of 874 (1.8%). Median (interquartile range) duration of ICU (n = 379) and hospital (n = 857) stay were 3.9 days (2-7.7 d) and 4 days (1.9-7.5 d), respectively. For patients with 28-day data, survival was 679 of 787, 86.3% with 13.4% lost to follow-up, and 0.3% deceased. CONCLUSIONS: In this observational, multicenter registry of children with coronavirus disease 2019, ICU admission was common. Older age, fever, multisystem inflammatory syndrome in children, and seizure disorder were independently associated with ICU admission, and mortality was lower among children than mortality reported in adults.

CovXmlc: High performance COVID-19 detection on X-ray images using Multi-Model classification.

The Coronavirus Disease 2019 (COVID-19) outbreak has a devastating impact on health and the economy globally, that's why it is critical to diagnose positive cases rapidly. Currently, the most effective test to detect COVID-19 is Reverse Transcription-polymerase chain reaction (RT-PCR) which is time-consuming, expensive and sometimes not accurate. It is found in many studies that, radiology seems promising by extracting features from X-rays. COVID-19 motivates the researchers to undergo the deep learning process to detect the COVID- 19 patient rapidly. This paper has classified the X-rays images into COVID- 19 and normal by using multi-model classification process. This multi-model classification incorporates Support Vector Machine (SVM) in the last layer of VGG16 Convolution network. For synchronization among VGG16 and SVM we have added one more layer of convolution, pool, and dense between VGG16 and SVM. Further, for transformations and discovering the best result, we have used the Radial Basis function. CovXmlc is compared with five existing models using different parameters and metrics. The result shows that our proposed CovXmlc with minimal dataset reached accuracy up to 95% which is significantly higher than the existing ones. Similarly, it also performs better on other metrics such as recall, precision and f-score.

Horizontal Transmission of COVID-19 in a 24-Week Premature Infant and Post-discharge Follow-Up.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has rapidly spread across the globe. The clinical spectrum of infection with SARS-CoV-2 among the most vulnerable extremely premature patient population in the neonatal intensive care units (NICUs), particularly those with chronic lung disease (CLD), remains unclear. Additionally, post-COVID conditions have been described in children with limited published data among infants. Symptoms in children appear similar to those described in the adults. We report a case of SARS-CoV-2 infection in a 24-week preterm infant with CLD acquired via horizontal transmission while still in the NICU. We also provide follow-up data on patient until one year post-discharge. Our patient developed fever prompting testing for SARS-CoV-2. Although extremely premature infants with CLD are known to be at high risk for morbidities if they acquire respiratory viral infections, infection with SARS-CoV-2 in this case report presented with relatively mild clinical symptoms. He remained clinically stable on respiratory support (nasal cannula) with eventual weaning to room air. Our patient was followed until one year post-discharge (chronological age: 20 months) and had follow-up by various subspecialties for chronic lung disease, hypothyroidism, chronic kidney disease, and poor growth. We did not observe any specific post-COVID symptoms. This case illustrates that horizontal transmission of SARS-CoV-2 infection among extremely premature infants with CLD is possible in the NICU but likely presents with mild clinical symptoms during acute infection and less chances of post-COVID conditions. Additionally, this case highlights the need for adherence to infection prevention guidelines to prevent nosocomial transmission amid the ongoing pandemic.

Breast Milk and Breastfeeding of Infants Born to SARS-CoV-2 Positive Mothers: A Prospective Observational Cohort Study.

OBJECTIVE: There are limited published data on the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus from mothers to newborns through breastfeeding or from breast milk. The World Health Organization released guidelines encouraging mothers with suspected or confirmed COVID-19 to breastfeed as the benefits of breastfeeding outweighs the possible risk of transmission. The objective of this study was to determine if SARS-CoV-2 was present in the breast milk of lactating mothers who had a positive SARS-CoV-2 nasopharyngeal swab test prior to delivery, and the clinical outcomes for their newborns. STUDY DESIGN: This was a single-center, observational, prospective cohort study. Maternal-newborn dyads that delivered at New York University Langone Hospital Brooklyn with confirmed maternal SARS-CoV-2 positive screen test at the time of admission were recruited for the study. Breast milk samples were collected during postpartum hospitalization and tested for the presence of SARS-CoV-2 genes N1 and N2 by two-step reverse transcription polymerase chain reaction. Additionally, the clinical characteristics of the maternal newborn dyad, results of nasopharyngeal SARS-CoV-2 testing, and neonatal follow-up data were collected. RESULTS: A total of 19 mothers were included in the study and their infants who were all fed breast milk. Breast milk samples from 18 mothers tested negative for SARS-CoV-2, and 1 was positive for SARS-CoV-2 RNA. The infant who ingested the breast milk that tested positive had a negative nasopharyngeal test for SARS-CoV-2, and had a benign clinical course. There was no evidence of significant clinical infection during the hospital stay or from outpatient neonatal follow-up data for all the infants included in this study. CONCLUSION: In a small cohort of SARS-CoV-2 positive lactating mothers giving birth at our institution, most of their breast milk samples (95%) contained no detectable virus, and there was no evidence of COVID-19 infection in their breast milk-fed neonates. KEY POINTS: · Breast milk may rarely contain detectable SARS-CoV-2 RNA and was not detected in asymptomatic mothers.. · Breast milk with detectable SARS-CoV-2 RNA from a symptomatic mother had no clinical significance for her infant.. · Breast feeding with appropriate infection control instructions appears to be safe in mother with COVID infection..

Characteristics of Hospitalized Children With SARS-CoV-2 in the New York City Metropolitan Area.

OBJECTIVES: To describe the characteristics of hospitalized children with severe acute respiratory syndrome coronavirus 2 in New York City metropolitan area. PATIENTS AND METHODS: This was a multicenter, retrospective cohort study at 4 hospitals comprising 82 hospitalized children (0-21 years) who tested positive for severe acute respiratory syndrome coronavirus 2 after symptoms and risk screening between March 1 and May 10, 2020. We subdivided patients on the basis of their admission to acute or critical care units and by age groups. Further subanalyses were performed between patients requiring respiratory support or no respiratory support. RESULTS: Twenty-three (28%) patients required critical care. Twenty-nine (35%) patients requiring respiratory support, with 9% needing mechanical ventilation, and 1 required extracorporeal support. All patients survived to discharge. Children with any comorbidity were more likely to require critical care (70% vs 37%, P = .008), with obesity as the most common risk factor for critical care (63% vs 28%, P = .02). Children with asthma were more likely to receive respiratory support (28% vs 8%, P = .02), with no difference in need for critical care (P = .26). Children admitted to critical care had higher rates of renal dysfunction at presentation (43% vs 10%, P = .002). CONCLUSIONS: Children with comorbidities (obesity and asthma in particular) were at increased risk for critical care admission and/or need for respiratory support. Children with renal dysfunction at presentation were more likely to require critical care.

Cardiac Findings in Pediatric Patients With Multisystem Inflammatory Syndrome in Children Associated With COVID-19.

BACKGROUND: The overall severity of cardiac disease secondary to acute SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) infection in children appears to be much lower when compared with adults. However, the newly described multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019 (COVID-19) has been associated with cardiac complications. METHODS: We reviewed the clinical course and cardiac testing results in pediatric patients hospitalized with MIS-C at 2 large hospital systems in the New York City metropolitan area over a 3-month period. RESULTS: Of the 33 patients (median age 2.8 years) in the study cohort, 24 (73%) had at least one abnormality in cardiac testing: abnormal electrocardiogram (48%), elevated brain natriuretic peptide (43%), abnormal echocardiogram (30%), and/or elevated troponin (21%). Electrocardiogram and echocardiogram abnormalities all resolved by the 2-week outpatient follow-up cardiology visit. CONCLUSION: While 73% of pediatric patients with MIS-C had evidence of abnormal cardiac testing on hospital admission in our study, all cardiac testing was normal by outpatient hospital discharge follow-up. Cardiac screening tests should be performed in all patients diagnosed with MIS-C given the high rate of abnormal cardiac findings in our study cohort.

Outcomes of Maternal-Newborn Dyads After Maternal SARS-CoV-2.

BACKGROUND AND OBJECTIVES: Infection with a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global pandemic. There are limited data describing the impact of SARS-CoV-2 infection on pregnant mothers and their newborns. The objective of this study is to describe characteristics and outcomes of maternal-newborn dyads with confirmed maternal SARS-CoV-2. METHODS: This was a multicenter, observational, descriptive cohort study with data collection from charts of maternal-newborn dyads who delivered at 4 major New York City metropolitan area hospitals between March 1 and May 10, 2020, with maternal SARS-CoV-2 infection. RESULTS: There were a total of 149 mothers with SARS-CoV-2 infection and 149 newborns analyzed (3 sets of twins; 3 stillbirths). Forty percent of these mothers were asymptomatic. Approximately 15% of symptomatic mothers required some form of respiratory support, and 8% required intubation. Eighteen newborns (12%) were admitted to the ICU. Fifteen (10%) were born preterm, and 5 (3%) required mechanical ventilation. Symptomatic mothers had more premature deliveries (16% vs 3%, P = .02), and their newborns were more likely to require intensive care (19% vs 2%, P = .001) than asymptomatic mothers. One newborn tested positive for SARS-CoV-2, which was considered a case of horizontal postnatal transmission. CONCLUSIONS: Although there was no distinct evidence of vertical transmission from mothers with SARS-CoV-2 to their newborns, we did observe perinatal morbidities among both mothers and newborns. Symptomatic mothers were more likely to experience premature delivery and their newborns to require intensive care.

Neonate Born to a Mother with a Diagnosis of Suspected Intra-Amniotic Infection versus COVID-19 or Both.

A diagnosis of intra-amniotic infection is typically made based on clinical criteria, including maternal intrapartum fever and one or more of the following: maternal leukocytosis, purulent cervical drainage, or fetal tachycardia. The diagnosis can also be made in patients with an isolated fever of 39°C, or greater, without any other clinical risk factors present. Coronavirus disease 2019 (COVID-19), caused by the virus SARS-CoV-2, has been noted to have varying signs and symptoms over the course of the disease including fever, cough, fatigue, anorexia, shortness of breath, sputum production, and myalgia. In this report, we detail a case of a newborn born to a mother with a clinical diagnosis of intra-amniotic infection with maternal fever and fetal tachycardia, who was then found to be SARS-CoV-2 positive on testing. Due to the varying presentation of COVID-19, this case illustrates the low threshold needed to test mothers for SARS-CoV-2 in order to prevent horizontal transmission to neonates and to healthcare providers.

Neonatal Intensive Care Unit Preparedness for the Novel Coronavirus Disease-2019 Pandemic: A New York City Hospital Perspective

In January 2020, China reported a cluster of cases of pneumonia associated with a novel pathogenic coronavirus provisionally named Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2). Since then, Coronavirus Disease 2019 (COVID-19) has been reported in more than 180 countries with approximately 3 million known infections and more than 210,000 deaths attributed to this disease. The majority of confirmed COVID-19 cases have been reported in adults, especially older individuals with co-morbidities. Children have had a relatively lower rate and a less serious course of infection as reported in the literature to date. One of the most vulnerable pediatric patient populations is cared for in the neonatal intensive care unit. There is limited data on the effect of COVID-19 in fetal life, and among neonates after birth. Therefore there is an urgent need for proactive preparation, and planning to combat COVID-19, as well as to safeguard patients, their families, and healthcare personnel. This review article is based on the Centers for Disease Control and Prevention's (CDC) current recommendations for COVID-19 and its adaptation to our local resources. The aim of this article is to provide basic consolidated guidance and checklists to clinicians in the neonatal intensive care units in key aspects of preparation needed to counter exposure or infection with COVID-19. We anticipate that CDC will continue to update their guidelines regarding COVID-19 as the situation evolves, and we recommend monitoring CDC's updates for the most current information.
