BACKGROUND:Few reports explore the frequency and factors associated with diagnostic ultrasound (US) for midgut volvulus. OBJECTIVE:To evaluate predictive factors for diagnostic US for midgut volvulus and clinical outcomes of patients with non-diagnostic US. MATERIALS AND METHODS/METHODS:This retrospective study included infants imaged for midgut volvulus with US. Exams were rated as diagnostic (midgut volvulus present or absent) or non-diagnostic by a pediatric radiologist, and in cases of disagreement with the original report, an additional pediatric radiologist was the tie-breaker. For each exam, the following were recorded: age, weight, respiratory support, exam indication, sonographer experience, and gaseous dilated bowel loops on radiography. Logistic regression models with "stepwise" variable selection were used to investigate the association of diagnostic US for midgut volvulus with each of the independent variables. RESULTS:One hundred nineteen patients were imaged. US was diagnostic in 74% (88/119) of patients. In subsets of patients presenting with bilious emesis or age <28 days, US was diagnostic in 92% (22/24) and 90% (53/59), respectively. Logistic regression suggested that symptom type (bilious vs other) was the best predictor of diagnostic US (type 3 P=0.02). Out of 26 patients with available radiographs, US was diagnostic in 92% (12/13) of patients without bowel dilation on radiographs compared to 62% (8/13) of patients with bowel dilation (P=0.16). Weight, respiratory support, and sonographer experience did not differ between groups. Two sick neonates, ages 2 days and 30 days, in whom the primary clinical concern was dropping hematocrit and sepsis, respectively, had non-diagnostic ultrasounds in the setting of bowel dilation on radiography. Both were found to have midgut volvulus at surgery and both expired. CONCLUSION/CONCLUSIONS:US was most frequently diagnostic in patients with bilious emesis or age less than 28 days. Non-diagnostic US for midgut volvulus must prompt a predetermined follow-up strategy, such as an additional imaging study (e.g., upper GI series), particularly in a sick child, as non-diagnostic US may miss midgut volvulus.

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..

Preterm infants are known to have long-term healthcare needs. With advances in neonatal medical care, younger and more preterm infants are surviving, placing a subset of the general population at risk of long-term healthcare needs. Oral feeding problems in this population often play a substantial yet under-appreciated role. Oral feeding competency in preterm infants is deemed an essential requirement for hospital discharge. Despite achieving discharge readiness, feeding problems persist into childhood and can have a residual impact into adulthood. The early diagnosis and management of feeding problems are essential requisites to mitigate any potential long-term challenges in preterm-born adults. This review provides an overview of the physiology of swallowing and oral feeding skills, disruptions to oral feeding in preterm infants, the outcomes of preterm infants with feeding problems, and an algorithmic approach to the evaluation and management of neonatal feeding problems.

BACKGROUND:Baby-Friendly hospitals encourage rooming-in newborns with mothers. In our institution, we noticed increased incidence of hypothermia following Baby-Friendly designation. We aimed to reduce the incidence of hypothermia in the mother-baby-unit to <15% and to decrease the rate of isolated hypothermia admissions to the neonatal intensive care unit (NICU) by 20% over two years. METHODS:After a retrospective review of newborns ≥35 weeks gestation in the mother-baby-unit with hypothermia, we implemented multiple interventions such as nursing education, hypothermia algorithm, Kamishibai cards, and Key cards. RESULTS:Hypothermia incidence in the mother-baby-unit decreased from 20.9 to 14.5% (p < 0.001) and infants requiring NICU admission decreased by 71% (p < 0.001) following all interventions. Apart from nursing education, all interventions led to significant reductions in both outcomes from baseline. CONCLUSION/CONCLUSIONS:Instituting a hypothermia algorithm and utilizing K-cards and Key cards reduces the incidence of hypothermia in the mother-baby-unit and NICU admissions for isolated hypothermia.

BACKGROUND:Central line-associated bloodstream infections (CLABSIs) are major contributors to preventable harm in the inpatient paediatric setting. Despite multiple guidelines to reduce CLABSI, sustaining reliable central line maintenance bundle compliance remains elusive. We identified frontline and family engagement as key drivers for this initiative. The baseline CLABSI rate for all our paediatric inpatient units (January 2016-January 2017) was 1.71/1000 central line days with maintenance bundle compliance at 87.9% (monthly range 44%-100%). OBJECTIVE:To reduce CLABSI by increasing central line maintenance bundle compliance to greater than 90% using kamishibai card (K-card) audits and family 'key card' education. METHODS:We transitioned our central line maintenance bundle audits from checklists to directly observed K-card audits. K-cards list the central line maintenance bundle elements to be reviewed with frontline staff. Key cards are cue cards developed using a plain-language summary of CLABSI K-cards and used by frontline staff to educate families. Key cards were distributed to families of children with central lines to simultaneously engage patients, families and frontline staff after a successful implementation of the K-card audit process. A survey was used to obtain feedback from families. RESULTS:In the postintervention period (February 2017-December 2019), our CLABSI rate was 0.63/1000 central line days, and maintenance bundle compliance improved to 97.1% (monthly range 86%-100%, p<0.001). Of the 45 family surveys distributed, 20 (44%) were returned. Nineteen respondents (95%) reported being extremely satisfied with the key card programme and provided positive comments. CONCLUSION/CONCLUSIONS:Combining the key card programme with K-card audits was associated with improved maintenance bundle compliance and a reduction in CLABSI. This programme has the potential for use in multiple healthcare improvement initiatives.

Neonates born to mothers with coronavirus disease 2019 (COVID-19) have been largely asymptomatic based on initial reports. All neonates born to mothers with COVID-19 have tested negative for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in our institution (published data as of April 12, 2020). As novel presentations of COVID-19, such as multisystem inflammatory syndrome in children are being increasingly reported, we raise the possibility of increased incidence of pneumothorax in neonates born to SARS-CoV-2-positive mothers. Two recently described neonates with COVID-19 infection were noted to have pneumothoraces. We describe two SARS-CoV-2-negative neonates born to COVID-19-positive mothers at 38 and 33 weeks, respectively, admitted to our neonatal intensive care unit for respiratory distress and subsequently developed pneumothoraces. As diverse clinical presentations in various age groups are being described, it becomes difficult to differentiate the increased incidence of complications related to an underlying illness, from COVID-19-related illness. It remains to be seen if neonates with in utero exposure to SARS-CoV-2 have an elevated inflammatory response with pneumonitis and exaggerated lung disease, similar to adult COVID-19 patients, due to in utero exposure.

OBJECTIVE:To determine whether delaying oral feeding until coming off NCPAP will alter feeding and respiratory-related morbidities in preterm infants. DESIGN/METHODS:In this retrospective pre-post analysis, outcomes were compared in two preterm infant groups (≤32 weeks gestation). Infants in Group 1 were orally fed while on NCPAP, while infants in Group 2 were only allowed oral feedings after ceasing NCPAP. RESULTS:Although infants in Group 2 started feeds at a later postmenstrual age (PMA), they reached full oral feeding at a similar PMA compared with Group 1. Interestingly, there was a positive correlation between the duration of oral feeding while on NCPAP and the time spent on respiratory support in Group 1. CONCLUSIONS:Delayed oral feeding until ceasing NCPAP did not contribute to feeding-related morbidities. We recommend caution when initiating oral feedings in preterm infants on NCPAP without evaluating the safety of the infants and their readiness for oral feedings.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to a global pandemic affecting 213 countries as of April 26, 2020. Although this disease is affecting all age groups, infants and children seem to be at a lower risk of severe infection, for reasons unknown at this time. We report a case of neonatal infection in New York, United States, and provide a review of the published cases. A 22-day-old, previously healthy, full-term neonate was hospitalized after presenting with a one-day history of fever and poor feeding. Routine neonatal sepsis evaluation was negative. SARS-CoV-2 polymerase chain reaction (PCR) testing was obtained, given rampant community transmission, which returned positive. There were no other laboratory or radiographic abnormalities. The infant recovered completely and was discharged home in two days once his feeding improved. The family was advised to self-quarantine to prevent the transmission of COVID-19. We believe that the mode of transmission was horizontal spread from his caregivers. This case highlights the milder presentation of COVID-19 in otherwise healthy, full-term neonates. COVID-19 must be considered in the evaluation of a febrile infant. Infants and children may play an important role in the transmission of COVID-19 in the community. Hence, with an understanding of the transmission patterns, parents and caregivers would be better equipped to limit the spread of the virus and protect the more vulnerable population.

Ewingella americana is a Gram-negative, catalase positive and anaerobic enterobacterium first described in 1983. Infections caused by this pathogen, such as bacteremia and pneumonia, are extremely rare and primarily occur in patients with underlying pathologies or immunosuppression. There is still a debate as to whether Ewingella americana is a real pathogen or if it can be considered an opportunistic infectious agent. We report the first documented case of Ewingella americana meningitis in literature and the first case of this pathogen causing infection in a newborn. Case presentation: A term newborn male was born via spontaneous vaginal delivery to a Gravida 2 Para 0, 28 year old woman with negative prenatal screening tests with a birth weight of 4.70 kilograms and Apgar scores of 9 and 9 at 1 and 5 minutes respectively. Rupture of membranes was 27 hours prior to delivery. Infant was noted to be febrile to 101°F at birth, so infant was admitted in the neonatal intensive care unit and started empirically on ampicillin and gentamycin. Cerebrospinal fluid (CSF) drawn due to irritability on day of life 1 presented normal cell and protein count but grew Gram negative rods after 2 days, identified subsequently as Ewingella americana; repeat CSF analysis done at 6 days of life showed pleocytosis. Brain MRI performed at 2 weeks of life showed leptomeningitis. The infant was treated with ceftazidime for 21 days from the first negative CSF culture. He has since followed up with the neurologist and infectious disease specialist. He had a normal electroencephalogram (EEG) and is meeting all developmental milestones at the 24 months of age follow up visit. Conclusion: Our case highlights that Ewingella americana can cause serious invasive infections such as meningitis in the neonatal period with minimal symptomatology. Antibiotic treatment in the neonatal period can present challenges due to the Ewingella americana's variable sensitivity. The role of these emerging low virulence organisms in causing infections has to be further elucidated, especially in vulnerable patients such as newborns.
