RESUMEN

BACKGROUND: In utero transmission of SARS coronavirus 2 (SARS-CoV-2) has not been fully investigated. We investigated whether newborns of mothers with COVID-19 during pregnancy might harbor SARS-CoV-2 in the gastrointestinal tract. METHODS: This cohort study investigated stool from 14 newborns born at 25-41 weeks admitted at delivery to our urban academic hospital whose mothers had COVID-19 during pregnancy. Eleven mothers had COVID-19 resolved more than 10 weeks before delivery. Newborn stool was evaluated for SARS-CoV-2 RNA, Spike protein, and induction of inflammatory cytokines interleukin-6 (IL-6) and interferon-γ (IFN-γ) in macrophages. RESULTS: Despite negative SARS CoV-2 nasal PCRs from all newborns, viral RNAs and Spike protein were detected in the stool of 11 out of 14 newborns as early as the first day of life and increased over time in 6. Stool homogenates from all 14 newborns elicited elevated inflammatory IL-6 and IFN-γ from macrophages. Most newborns were clinically well except for one death from gestational autoimmune liver disease and another who developed necrotizing enterocolitis. CONCLUSIONS: These findings suggest in utero transmission of SARS-CoV-2 and possible persistent intestinal viral reservoirs in the newborns. Further investigation is required to understand the mechanisms and their clinical implications. IMPACT: SARS-CoV-2 RNAs or Spike protein was detected in the stool of 11 out of 14 preterm newborns born to mothers with resolved COVID-19 weeks prior to delivery despite negative newborn nasal PCR swabs. These novel findings suggest risk of in utero SARS-CoV-2 transmission to the fetal intestine during gestation. The presence of SARS-CoV-2 RNAs and Spike protein in the intestines of newborns may potentially impact the development of the gut microbiome and the immune system; the long-term health impact on the preterm infants should be further investigated.

RESUMEN

This 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (CoSTR) for neonatal life support includes evidence from 7 systematic reviews, 3 scoping reviews, and 12 evidence updates. The Neonatal Life Support Task Force generally determined by consensus the type of evidence evaluation to perform; the topics for the evidence updates followed consultation with International Liaison Committee on Resuscitation member resuscitation councils. The 2020 CoSTRs for neonatal life support are published either as new statements or, if appropriate, reiterations of existing statements when the task force found they remained valid. Evidence review topics of particular interest include the use of suction in the presence of both clear and meconium-stained amniotic fluid, sustained inflations for initiation of positive-pressure ventilation, initial oxygen concentrations for initiation of resuscitation in both preterm and term infants, use of epinephrine (adrenaline) when ventilation and compressions fail to stabilize the newborn infant, appropriate routes of drug delivery during resuscitation, and consideration of when it is appropriate to redirect resuscitation efforts after significant efforts have failed. All sections of the Neonatal Resuscitation Algorithm are addressed, from preparation through to postresuscitation care. This document now forms the basis for ongoing evidence evaluation and reevaluation, which will be triggered as further evidence is published. Over 140 million babies are born annually worldwide (https://ourworldindata.org/grapher/births-and-deaths-projected-to-2100). If up to 5% receive positive-pressure ventilation, this evidence evaluation is relevant to more than 7 million newborn infants every year. However, in terms of early care of the newborn infant, some of the topics addressed are relevant to every single baby born.

RESUMEN

One hundred and nine preterm infants were studied to examine the relative effects of biologic/neurologic factors (length of hospital stay, 18 month cognitive status) and environment (socioeconomic status) on cognition in the toddler (18 months) and preschool periods (3 years). Length of hospital stay was significantly related to toddler cognitive outcome, and less so to preschool outcome. Socioeconomic status predicted only preschool cognitive outcome and not toddler outcome. Cognitive status at 18 months significantly predicted 3 year outcome, and there was relatively little change between those periods. Together, cognitive status at 18 months and socioeconomic status significantly predicted preschool IQ, accounting for 34% of the variance. Results showed that perinatal biologic risks became less salient while socioeconomic status became increasingly important at the preschool period. Relative lack of change in cognitive status indicated the importance of early cognitive evaluation in preterm infants.

RESUMEN

BACKGROUND: Neonatal mortality is a global challenge, with an estimated 1.3 million intrapartum stillbirths in 2015. The majority of these were found in low resource settings with limited options to intrapartum fetal heart monitoring devices. This trial compared frequency of abnormal fetal heart rate (FHR) detection and adverse perinatal outcomes (i.e. fresh stillbirths, 24-h neonatal deaths, admission to neonatal care unit) among women intermittently assessed by Doppler or fetoscope in a rural low-resource setting. METHODS: This was an open-label randomized controlled trial conducted at Haydom Lutheran Hospital from March 2013 through August 2015. Inclusion criteria were; women in labor, singleton, cephalic presentation, normal FHR on admission (120-160 beats/minute), and cervical dilatation ≤7 cm. Verbal consent was obtained. RESULTS: A total of 2684 women were recruited, 1309 in the Doppler and 1375 in the fetoscope arms, respectively. Abnormal FHR was detected in 55 (4.2%) vs 42 (3.1%). (RR = 1.38; 95%CI: 0.93, 2.04) in the Doppler and fetoscope arms, respectively. Bag mask ventilation was performed in 80 (6.1%) vs 82 (6.0%). (RR = 1.03; 95%CI: 0.76, 1.38) of neonates, and adverse perinatal outcome was comparable 32(2.4%) vs 35(2.5%). (RR = 0.9; 95%CI: 0.59, 1.54), in the Doppler and fetoscope arms, respectively. CONCLUSION: This trial failed to demonstrate a statistically significant difference in the detection of abnormal FHR between intermittently used Doppler and fetoscope and adverse perinatal outcomes. However, FHR measurements were not performed as often as recommended by international guidelines. Conducting a randomized controlled study in rural settings with limited resources is associated with major challenges. TRIAL REGISTRATION: This clinical trial was registered on April 2013 with registration number NCT01869582 .

RESUMEN

OBJECTIVE: To evaluate the association between planned home birth and neonatal hypoxic ischemic encephalopathy (HIE). METHODS: This is a case-control study in which a database of neonates who underwent head cooling for HIE at our institution from 2007 to 2011 was linked to New York City (NYC) vital records. Four normal controls per case were then randomly selected from the birth certificate data after matching for year of birth, geographic location, and gestational age. Demographic and obstetric information was obtained from the vital records for both the cases and controls. Location of birth was analyzed as hospital or out of hospital birth. Details from the out of hospital deliveries were reviewed to determine if the delivery was a planned home birth. Maternal and pregnancy characteristics were examined as covariates and potential confounders. Logistic regression was used to determine the odds of HIE by intended location of delivery. RESULTS: Sixty-nine neonates who underwent head cooling for HIE had available vital record data on their births. The 69 cases were matched to 276 normal controls. After adjusting for pregnancy characteristics and mode of delivery, neonates with HIE had a 44.0-fold [95% confidence interval (CI) 1.7-256.4] odds of having delivered out of hospital, whether unplanned or planned. Infants with HIE had a 21.0-fold (95% CI 1.7-256.4) increase in adjusted odds of having had a planned home birth compared to infants without HIE. CONCLUSION: Out of hospital birth, whether planned home birth or unplanned out of hospital birth, is associated with an increase in the odds of neonatal HIE.

RESUMEN

INTRODUCTION: Facemask ventilation is a crucial, but challenging, element of neonatal resuscitation.In a previously reported study, instructor-led training using a novel neonatal simulator resulted in high-level ventilation competence for health care providers (HCPs) involved in newborn resuscitation. The aim of this study was to identify the optimal frequency and dose of simulation training to maintain this competence level. METHODS: Prospective observational study of HCPs training through 9 months. All training was logged. Overall ventilation competence scores were calculated for each simulation case, incorporating 7 skill elements considered important for effective ventilation.Overall scores and skill elements were analyzed by generalized linear mixed effects models using frequency (number of months of 9 where training occurred and total number of training sessions in 9 months) and dose (total number of cases performed) as predictors. Training loads (frequency + dose) predictive of high scores were projected based on estimated marginal probabilities of successful outcomes. RESULTS: A total of 156 HCPs performed 4348 training cases. Performing 5 or more sessions in 9 months predicted high global competence scores (>28/30). Frequency was the best predictor for 4 skill elements; success in maintaining airway patency and ventilation fraction was predicted by performing training in, respectively, 2 and 3 months of 9, whereas for avoiding dangerously high inflating pressures and providing adequate mask seal, 5 and 6 sessions, respectively, over the 9 months, predicted success. Skills reflecting global performance (successful resuscitation and valid ventilations) and ventilation rate were more dose-dependent. CONCLUSIONS: Training frequency is important in maintaining neonatal ventilation competence. Training dose is important for some skill elements. This offers the potential for individualized training schedules.

RESUMEN

Most recommendations on cardiopulmonary resuscitation were developed from the perspective of high-resource settings with the aim of applying them in these settings. These so-called international guidelines are often not applicable in low-resource settings. Organisations including the International Liaison Committee on Resuscitation (ILCOR) have not sufficiently addressed this problem. We formed a collaborative group of experts from various settings including low-income, middle-income, and high-income countries, and conducted a prospective, multiphase consensus process to formulate this ILCOR Task Force statement. We highlight the discrepancy between current cardiopulmonary resuscitation guidelines and their applicability in low-resource settings. Successful existing initiatives such as the Helping Babies Breathe programme and the WHO Emergency Care Systems Framework are acknowledged. The concept of the chainmail of survival as an adaptive approach towards a framework of resuscitation, the potential enablers of and barriers to this framework, and gaps in the knowledge are discussed, focusing on low-resource settings. Action points are proposed, which might be expanded into future recommendations and suggestions, addressing a large diversity of addressees from caregivers to stakeholders. This statement serves as a stepping-stone to developing a truly global approach to guide resuscitation care and science, including in health-care systems worldwide.

RESUMEN

OBJECTIVES: To determine whether the two-thumb technique is superior to the two-finger technique for administering chest compressions using the floor surface and the preferred location for performing infant cardiopulmonary resuscitation (CPR) (ie, floor, table, or radiant warmer). STUDY DESIGN: Twenty Neonatal Resuscitation Program trained medical personnel performed CPR on a neonatal manikin utilizing the two-thumb vs two-finger technique, a compression to ventilation ratio of 30:2 for 2 minutes in random order on the floor, table, and radiant warmer. RESULTS: Compression depth favored the two-thumb over two-finger technique on the floor (27 ± 8 mm vs 23 ± 7), table (26 ± 7 mm vs 22 ± 7), and radiant warmer (29 ± 4 mm vs 23 ± 4) (all P < .05). Per individual subject, the compression depth varied widely using both techniques and at all surfaces. More variability between compressions was observed with the two-finger vs two-thumb technique on all surfaces (P < .05). Decay in compression over time occurred and was greater with the two-finger vs two-thumb technique on the floor (-5 ± 7 vs -1 ± 6 mm; P < .05) and radiant warmer (-3 ± 6 vs -0.3 ± 2 mm; P < .05), compared with the table (-3 ± 9 vs -4 ± 5 mm). Providers favored the table over radiant warmer, with the floor least preferred and most tiring. CONCLUSIONS: The two-thumb technique is superior to the two-finger technique, achieving greater depth, less variability, and less decay over time. The table was considered most comfortable and less tiring. The two-thumb technique should be the preferred method for teaching lay persons infant CPR preferably using an elevated firm surface.

RESUMEN

The objective of this chapter is to trace the evolution of intraventricular hemorrhage in the premature infant highlighting the importance of the germinal matrix, a critical role for cerebral blood flow changes in the genesis of hemorrhage, clinical factors that increase the bleeding risk, and potential preventative strategies. In 1976, neuropathological studies demonstrated capillary rupture within the germinal matrix as the precursor of hemorrhage. In 1980, introduction of cranial ultrasound facilitated diagnosis of intraventricular hemorrhage. In 1979, loss of cerebral autoregulation in sick newborn infants was demonstrated. In the 1980's, studies demonstrated the importance of intravascular factors in provoking hemorrhage. In 1983, the association of cerebral blood flow velocity fluctuations and subsequent hemorrhage was demonstrated. In 1994, antenatal steroids use to accelerate lung development was recommended. This was associated with an unanticipated reduction in hemorrhage. In the mid 1990's early indomethacin administration was associated with a reduction of severe hemorrhage.

RESUMEN

Maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can present with or without symptoms at the time of birth. Symptomatic mothers are more likely be associated with preterm births. Population studies demonstrate a consistent association of SARS-CoV-2 infection and a reduction in preterm birth rate. Newborns with positive SARS-CoV-2 test results appear to have minimal burden of illness that is directly associated with a viral infection. Neonatal mortality directly related to SARS-CoV-2 is extremely rare. Maternal vaccination in pregnant women leads to maternal antibody production, and this can occur as early as 5 days after the first vaccination dose.

RESUMEN

Delivery room management of infants delivered through meconium stained amniotic fluid has evolved over the past four decades. The burden of disease weighs more heavily in low- and middle-resource areas. Current information does not allow for precise prediction of infants that will require resuscitation at delivery versus those that need simple stabilization. Optimal care of newborns requires assessment of risk factors and obstetrical and pediatric team preparation to respond to the needs of the newborn.

RESUMEN

OBJECTIVE: A positive significant association has been found between behavior problems and lower cognition in very low birthweight (VLBW) preterm children at school age, but there is relatively little information about whether such an association exists in toddlers and on the continuity of this association. The aim of this study was to assess if there is a relationship between behavior problems and cognitive performance in VLBW preterm children at 18 months post conception and 3 years old, independent of socioeconomic status and sex. METHOD: Parents of 124 preterm children completed a behavior rating questionnaire (Child Behavior Checklist 1.5-5) to measure behavior problems characteristic of preterm children (Withdrawn, Anxious/Depressed, and Attention Problems). Children completed the Cognitive Scale of the Bayley Scales of Infant Development-III at 18 months and the Wechsler Preschool and Primary Scale (III or IV) at 36 months old. Socioeconomic status (SES), sex, and diagnoses of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) at 3 years were recorded for each child. RESULTS: Withdrawn problems at 18 months were associated with lower cognitive scores at 18 months and both Withdrawn problems at 18 months and 36 months were associated with lower cognitive scores at 36 months. Increases in Attention Problems scores from 18 to 36 months were associated with decreases in cognitive scores over that period. Lower SES was associated with lower cognitive scores at 36 months and decreases in cognitive scores between 18 and 36 months. Sex was not related to behavior problems or cognition. Diagnoses of ASD and ADHD were significantly associated with increased Withdrawn behavior and Attention Problems, respectively. CONCLUSIONS: The early association of Withdrawn behaviors with less favorable cognitive performance at 18 months and 36 months and the relationship between increases in Attention Problems with decreases in cognitive scores between the toddler and preschool period indicate the need for early assessment of and intervention for behavior problems, as well as concurrent cognitive delays, in VLBW preterm children.

RESUMEN

Background: Training in the Helping Babies Breathe (HBB) Program has been associated with a reduction in early neonatal mortality rate (ENMR), the neonatal mortality rate (NMR), and fresh stillbirth rate (FSBR) in low- and middle-income countries (LMICs). This program was implemented in five different healthcare facilities in the Oliver Reginald Tambo (ORT) District, South Africa from September 2015 to December 2020. Objective: To determine and compare the FSBR, ENMR, and NMR between 2015 before initiation of the program (baseline) and subsequent years up to 2020 following the implementation of facility-based training of HBB in five hospitals in ORT District. Methods: Records of perinatal statistics from January 2015 to December 2020 were reviewed to calculate FSBR, ENMR, and NMR. Data were collected from the five healthcare facilities which included two district hospitals (Hospital A&B), two regional hospitals (Hospital C&D), and one tertiary hospital (Hospital E). Comparisons were made between pre- (2015) and post- (2016-2020) HBB implementation periods. Differences in changes over time were also assessed using linear regression analysis. Results: There were 19,275 births in 2015, increasing to 22,192 in 2020 with the majority (55.3%) of births occurring in regional hospitals. There were significant reductions in ENMR (OR-0.78, 95% CI 0.70-0.87) and NMR (OR-0.81, 95% CI 0.73-0.90), but not in FSBR, in the five hospitals combined when comparing the two time periods. Significant reduction was also noted in trends over time in ENMR (r 2 = 0.45, p = 0.001) and NMR (r 2 = 0.23, p = 0.026), but not in FSBR (r 2 = 0.0, p = 0.984) with all hospitals combined. In looking at individual hospitals, Hospital A (r 2 = 0.61, p < 0.001) and Hospital E (r 2 = 0.19, p = 0.048) showed a significant reduction in ENMR over time, but there were no significant changes in all mortality rates for Hospitals B, C, and D, and for the district or regional hospitals combined. Conclusion: There was an overall reduction of 22% and 19% in ENMR and NMR, respectively, from pre- to post-HBB implementation periods, although there were variations from year to year over the 5-year period and, across hospitals. These differences suggest that there were other factors that affected the perinatal/neonatal outcomes in the hospital sites in addition to the implementation of training in HBB.

RESUMEN

CONTEXT: For many years the International Liaison Committee on Resuscitation has recommended the use of tactile stimulation for initial management of infants born with inadequate respiratory effort at birth without systematically examining its effectiveness. OBJECTIVE: Systematic review to compare the effectiveness of tactile stimulation with routine handling in newly born term and preterm infants. DATA SOURCES: Medline, Embase, Cochrane CENTRAL, along with clinical trial registries. STUDY SELECTION: Randomized and non-randomized studies were included based on predetermined criteria. DATA EXTRACTION: Data were extracted independently by authors. Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) was used to assess risk of bias in non-randomized studies. Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used to assess the certainty of evidence. RESULTS: Among 2455 unique articles identified, 2 observational studies were eligible and qualitatively summarized. Because one of the studies was at critical risk of bias, only the other study including 243 preterm infants on continuous positive airway pressure with clinical indications for tactile stimulation was analyzed. It showed a reduction in tracheal intubation in infants receiving tactile stimulation compared with no tactile stimulation (12 of 164 vs 14 of 79, risk ratio of 0.41 [95% confidence interval 0.20 to 0.85]); however, the certainty of evidence was very low. LIMITATIONS: The available data were limited and only from observational studies. CONCLUSIONS: A potential benefit of tactile stimulation was identified but was limited by the very low certainty of evidence. More research is suggested to evaluate the effectiveness as well as the optimal type and duration of tactile stimulation.

RESUMEN

The goal of therapy for bradycardia or tachycardia is to rapidly identify and treat patients who are hemodynamically unstable or symptomatic due to the arrhythmia. Drugs or, when appropriate, pacing may be used to control unstable or symptomatic bradycardia. Cardioversion or drugs or both may be used to control unstable or symptomatic tachycardia. ACLS providers should closely monitor stable patients pending expert consultation and should be prepared to aggressively treat those with evidence of decompensation.

RESUMEN

OBJECTIVE: To review and revise the 1987 pediatric brain death guidelines. METHODS: Relevant literature was reviewed. Recommendations were developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. CONCLUSIONS AND RECOMMENDATIONS: 1) Determination of brain death in term newborns, infants, and children is a clinical diagnosis based on the absence of neurologic function with a known irreversible cause of coma. Because of insufficient data in the literature, recommendations for preterm infants <37 wks gestational age are not included in this guideline. 2) Hypotension, hypothermia, and metabolic disturbances should be treated and corrected and medications that can interfere with the neurologic examination and apnea testing should be discontinued allowing for adequate clearance before proceeding with these evaluations. 3) Two examinations, including apnea testing with each examination separated by an observation period, are required. Examinations should be performed by different attending physicians. Apnea testing may be performed by the same physician. An observation period of 24 hrs for term newborns (37 wks gestational age) to 30 days of age and 12 hrs for infants and children (>30 days to 18 yrs) is recommended. The first examination determines the child has met the accepted neurologic examination criteria for brain death. The second examination confirms brain death based on an unchanged and irreversible condition. Assessment of neurologic function after cardiopulmonary resuscitation or other severe acute brain injuries should be deferred for ≥24 hrs if there are concerns or inconsistencies in the examination. 4) Apnea testing to support the diagnosis of brain death must be performed safely and requires documentation of an arterial Paco2 20 mm Hg above the baseline and ≥60 mm Hg with no respiratory effort during the testing period. If the apnea test cannot be safely completed, an ancillary study should be performed. 5) Ancillary studies (electroencephalogram and radionuclide cerebral blood flow) are not required to establish brain death and are not a substitute for the neurologic examination. Ancillary studies may be used to assist the clinician in making the diagnosis of brain death a) when components of the examination or apnea testing cannot be completed safely as a result of the underlying medical condition of the patient; b) if there is uncertainty about the results of the neurologic examination; c) if a medication effect may be present; or d) to reduce the interexamination observation period. When ancillary studies are used, a second clinical examination and apnea test should be performed and components that can be completed must remain consistent with brain death. In this instance, the observation interval may be shortened and the second neurologic examination and apnea test (or all components that are able to be completed safely) can be performed at any time thereafter. 6) Death is declared when these criteria are fulfilled.
