End-of-Life Care for Newborn Infants: A Multicenter Real-Life Prospective Study.

INTRODUCTION: Most neonatal deaths in industrialized countries follow a process of redirection of care. The objectives of this study were to describe how neonates die in a middle-income country, whether there was redirection of care, and the reason for this decision. METHODS: This was a prospective, multicenter, cross-sectional study. Neonates who died in the delivery room or in the neonatal intensive care unit in 97 hospitals over a 6-month period were included. After each neonatal death, one investigator interviewed a member of the healthcare team who had been involved in the end-of-life care process. Perinatal data, conditions that led to death, whether there was redirection of care, and details of the end-of-life process were recorded. RESULTS: Data from 697 neonatal deaths were analyzed, which represent 80% of the total deaths occurring in Argentina in that period. The main causes of death were complications of prematurity (47%) and congenital anomalies (27%). Overall, 32% of neonates died after a process of redirection of care, and this was less frequent in the neonatal intensive care unit (28%) than in the delivery room (70%, p < 0.001). The reasons for withholding/withdrawing care were inevitable death (75%) and severe compromise of expected quality of life (25%). Redirection of care consisted in withholding therapies in 66% and withdrawal in 34%. A diagnosis of a major congenital anomaly increased the odds of redirection of care (OR 5.45; 95% CI: 3.59-8.27). CONCLUSION: Most neonates who die in Argentina do so while receiving full support. Redirection of care mainly follows a condition of inevitable death.

Impact of perinatal COVID on fetal and neonatal brain and neurodevelopmental outcomes.

After three years of the COVID-19 pandemic, we have learned many aspects of the disease and the virus: its molecular structure, how it infects human cells, the clinical picture at different ages, potential therapies, and the effectiveness of prophylaxis. Research is currently focused on the short- and long-term consequences of COVID-19. We review the available information on the neurodevelopmental outcome of infants born during the pandemic from infected and non-infected mothers, as well as the neurological impact of neonatal SARS-CoV-2 infection. We also discuss the mechanisms that could potentially affect the fetal or neonatal brain including direct impact after vertical transmission, maternal immune activation with a proinflammatory cytokine storm, and finally the consequences of complications of pregnancy secondary to maternal infection that could affect the fetus. Several follow-up studies have noted a variety of neurodevelopmental sequelae among infants born during the pandemic. There is controversy as to the exact etiopathogenesis of these neurodevelopmental effects: from the infection itself or as a result of parental emotional stress during that period. We summarize case reports of acute neonatal SARS-CoV-2 infections associated with neurological signs and neuroimaging changes. Many infants born during previous pandemics caused by other respiratory viruses demonstrated serious neurodevelopmental and psychological sequelae that were only recognized after several years of follow-up. It is essential to warn health authorities about the need for very long-term continuous follow up of infants born during the SARS-CoV-2 pandemic for early detection and treatment that could help mitigate the neurodevelopmental consequences of perinatal COVID-19.

Can Intubation Be Improved with Endotracheal Tubes Marked with a Color Scale? Randomized Controlled Study.

OBJECTIVE: This study aimed to assess if a color scale in the endotracheal tube (ETT) can help operators to correctly select the size and depth of placement of the ETT and decrease the time required to complete the procedure and compared with the usual numeric ETT scale in a mannequin model. STUDY DESIGN: The study was conducted in eight centers. Each size of the ETT was identified with a different color. The experimental ETTs had two different colored areas, one for the mouthpiece and another to identify where the ETT should be taped above the lip (an area of 1 cm. The operators were trained as part of the protocol using an instructional video. Four clinical scenarios requiring endotracheal intubation were designed and randomly assigned. Each operator had to select the size and depth of ETT based on the birth weight (BW), and then had to perform four intubations. RESULTS: A total of 108 operators performed 432 intubations. No differences were found in the correct placement and selection of the ETT. Median time (in seconds) required for intubation using numeric versus experimental tube was: for ETT Ø NRP (Neonatal Resuscitation Program) 2.5, 11.5 versus 8 (p < 0.001), ETT Ø 3, 12 versus 10 (p < 0.001), ETT Ø 3.5, 15.5 versus12 (p = 0.003), ETT Ø 4, 12 versus11 (p = 0.019). CONCLUSION: No significant difference was observed in the selection and correct placement of the ETT. However, the intubation time was significantly shorter using the experimental ETT. This device could improve the effectiveness of intubation by reducing the time needed to properly place the ETT at mid trachea. KEY POINTS: · It is an innovative intervention to try to solve a great inconvenience of daily practice.. · The study also raises the difficulty in maintaining the ability of endotracheal intubation.. · It proposes a scale that ensures the correct location with a safe fixation zone..

Infección tardía por Streptococcus agalactiae asociada a la leche humana: reporte de 3 casos clínicos / Streptococcus agalactiae late onset infection associated with human milk: three cases report

La infección por estreptococo ß-hemolítico del grupo B o Streptococcus agalactiae puede causar morbilidad grave y mortalidad en los recién nacidos, especialmente en prematuros. Las estrategias de prevención actuales han sido eficaces en reducir la frecuencia de sepsis neonatal temprana ocasionada por transmisión vertical. La incidencia de sepsis tardía por dicho microrganismo no se ha modificado y la vía de infección es menos clara. En niños amamantados, la transmisión a través de la leche materna es posible. Se presentan tres casos de infección tardía por estreptococo ß-hemolítico del grupo B en recién nacidos prematuros alimentados con leche materna cuyas madres tenían mastitis. En todos los casos, tanto en el cultivo de la leche materna como en los hemocultivos de los neonatos se desarrolló el mismo microrganismo.

Group B ß-hemolytic Streptococcus or Streptococcus agalactiae is a major cause of morbidity and mortality in neonates, especially in premature infants. Current prevention strategies have been effective in reducing the frequency of early onset neonatal sepsis caused by vertical transmission. The incidence of late onset sepsis due to this microorganism has not changed and the route of infection is less clear. In breastfed infants, transmission through breast milk is possible. We report three cases of late group B ß-hemolytic streptococcal infection in breastfed preterm infants whose mothers had mastitis. In all cases, both the breast milk culture and the blood cultures of the neonates developed the same microorganism.

Maternal-Fetal Immunologic Response to SARS-CoV-2 Infection in a Symptomatic Vulnerable Population: A Prospective Cohort.

BACKGROUND: Coronavirus disease 2019 (COVID-19) disproportionally affects pregnant women and their newborn; however, little is known about variables that modulate maternal-fetal immune response to infection. METHODS: We prospectively studied socioeconomic, biologic, and clinical factors affecting humoral immunity in 87 unvaccinated pregnant women hospitalized in Buenos Aires for symptoms consistent with COVID-19. RESULTS: The number of days between symptom onset and childbirth predicted maternal and newborn virus spike protein receptor binding domain (RBD)-specific immunoglobulin G (IgG). These findings suggest newborns may benefit less when mothers deliver soon after COVID-19 infection. Similarly, a longer time between symptom onset and birth predicted higher in utero transfer of maternal IgG and its concentration in cord blood. Older gestational age at birth was associated with lower maternal to cord blood IgG ratio. Of women with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, 87% developed RBD-specific IgA responses in breast milk within 96 hours of childbirth. IgA was not significantly associated with time from infection but correlated with maternal serum IgG and placental transfer. CONCLUSIONS: These results demonstrate the combined role of biologic, clinical, and socioeconomic variables associated with maternal RBD-specific antibodies and supports early vaccination strategies for COVID-19 in socioeconomically vulnerable pregnant women.

Association between Intermittent Hypoxemia and Severe Bronchopulmonary Dysplasia in Preterm Infants.

Rationale: Bronchopulmonary dysplasia increases the risk of disability in extremely preterm infants. Although the pathophysiology remains uncertain, prior exposure to intermittent hypoxemia may play a role in this relationship. Objectives: To determine the association between prolonged episodes of intermittent hypoxemia and severe bronchopulmonary dysplasia. Methods: A post hoc analysis of extremely preterm infants in the Canadian Oxygen Trial who survived to 36 weeks' postmenstrual age was performed. Oxygen saturations <80% for ⩾1 minute and the proportion of time per day with hypoxemia were quantified using continuous pulse oximetry data that had been sampled every 10 seconds from within 24 hours of birth until 36 weeks' postmenstrual age. The study outcome was severe bronchopulmonary dysplasia as defined in the 2001 NIH Workshop Summary. Measurements and Main Results: Of 1,018 infants, 332 (32.6%) developed severe bronchopulmonary dysplasia. The median number of hypoxemic episodes ranged from 0.8/day (interquartile range, 0.2-1.1) to 60.2/day (interquartile range, 51.4-70.3) among the least and most affected 10% of infants. Compared with the lowest decile of exposure to hypoxemic episodes, the adjusted relative risk of severe bronchopulmonary dysplasia increased progressively from 1.72 (95% confidence interval, 1.55-1.90) at the 2nd decile to 20.40 (95% confidence interval, 12.88-32.32) at the 10th decile. Similar risk gradients were observed for time in hypoxemia. Significant differences in the rates of hypoxemia between infants with and without severe bronchopulmonary dysplasia emerged within the first week after birth. Conclusions: Prolonged intermittent hypoxemia beginning in the first week after birth was associated with an increased risk of developing severe bronchopulmonary dysplasia among extremely preterm infants.

Ischemic Lesions in the Brain of a Neonate With SARS-CoV-2 Infection.

AIM: To describe a term newborn with acquired severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and multisystem involvement including seizures associated to ischemic lesions in the brain. BACKGROUND: Coronavirus disease 2019 (COVID-19) is predominantly a respiratory infection, but it may affect many other systems. Most pediatric COVID-19 cases range from asymptomatic to mild-moderate disease. There are no specific clinical signs described for neonatal COVID-19 infections. In children, severe central nervous system compromise has been rarely reported. CASE DESCRIPTION: We describe a 17-day-old newborn who acquired a SARS-CoV-2 infection in a family meeting that was admitted for fever, seizures and lethargy and in whom consumption coagulopathy, ischemic lesions in the brain and cardiac involvement were documented. CONCLUSIONS: SARS-CoV-2 neonatal infection can be associated with multi-organic involvement. In our patient, significant central nervous system compromise associated to ischemic lesions and laboratory findings of consumption coagulopathy were found. CLINICAL SIGNIFICANCE: Although neonatal SARS-CoV-2 infections are infrequent, they can be associated with multi-organic involvement. Neonatologists and pediatricians should be aware of this unusual way of presentation of COVID-19 in newborn infants.

COVID-19 preparedness-a survey among neonatal care providers in low- and middle-income countries.

OBJECTIVE: To evaluate COVID-19 pandemic preparedness, available resources, and guidelines for neonatal care delivery among neonatal health care providers in low- and middle-income countries (LMICs) across all continents. STUDY DESIGN: Cross-sectional, web-based survey administered between May and June, 2020. RESULTS: Of 189 invited participants in 69 LMICs, we received 145 (77%) responses from 58 (84%) countries. The pandemic provides significant challenges to neonatal care, particularly in low-income countries. Respondents noted exacerbations of preexisting shortages in staffing, equipment, and isolation capabilities. In Sub-Saharan Africa, 9/35 (26%) respondents noted increased mortality in non-COVID-19-infected infants. Clinical practices on cord clamping, isolation, and breastfeeding varied widely, often not in line with World Health Organization guidelines. Most respondents noted family access restrictions, and limited shared decision-making. CONCLUSIONS: Many LMICs face an exacerbation of preexisting resource challenges for neonatal care during the pandemic. Variable approaches to care delivery and deviations from guidelines provide opportunities for international collaborative improvement.
