High Frequency Oscillatory Ventilation (HFOV) and Inhaled Nitric Oxide (iNO) Use During Neonatal Emergency Transport - Feasibility and Efficacy in India.

A retrospective study of 24 neonates to evaluate the feasibility and efficacy of high frequency oscillatory ventilation (HFOV) and inhaled nitric oxide (iNO) for transferring critically ill neonates to tertiary neonatal intensive care, who were transported by road ambulance was done. Efficacy was measured by clinical improvement, patient safety was assessed by comparing cardiorespiratory indicators before and after transport, and adverse events during transport. Significant oxygenation improvement was observed in neonates transported with HFOV ± iNO compared to earlier ventilator settings. Pre- and post-transport vital signs were stable, and no transport-related deaths occurred. A substantial rise in median SpO2 was seen after transfer [86 (81, 91) vs. 93 (89, 97) before transport, p <0.001]. Twelve of twenty-one newborns who received nitric oxide demonstrated significant improvement in oxygenation index (a 10% decrease from prior value). Overall survival was 70.8%, however non-transfer or inadequate respiratory treatment may have exacerbated mortality.

Mechanical power and normalized mechanical power in pediatric acute respiratory distress syndrome.

Background: Mechanical power (MP) refers to the energy transmitted over time to the respiratory system and serves as a unifying determinant of ventilator-induced lung injury. MP normalization is required to account for developmental changes in children. We sought to examine the relationship between mechanical energy (MEBW), MP normalized to body weight (MPBW), and MP normalized to respiratory compliance (MPCRS) concerning the severity and outcomes of pediatric acute respiratory distress syndrome (pARDS). Method: In this retrospective study, children aged 1 month to 18 years diagnosed with pARDS who underwent pressure-control ventilation for at least 24 h between January 2017 and September 2020 were enrolled. We calculated MP using Becher's equation. Multivariable logistic regression analysis adjusted for age, pediatric organ dysfunction score, and oxygenation index (OI) was performed to determine the independent association of MP and its derivatives 24 h after diagnosing pARDS with 28-day mortality. The association was also studied for 28 ventilator-free days (VFD-28) and the severity of pARDS in terms of OI. Results: Out of 246 admitted with pARDS, 185 were eligible, with an overall mortality of 43.7%. Non-survivors exhibited higher severity of illness, as evidenced by higher values of MP, MPBW, and MEBW. Multivariable logistic regression analysis showed that only MEBW but not MP, MPBW, or MPCRS at 24 h was independently associated with mortality [adjusted OR: 1.072 (1.002-1.147), p = 0.044]. However, after adjusting for the type of pARDS, MEBW was not independently associated with mortality [adjusted OR: 1.061 (0.992-1.136), p = 0.085]. After adjusting for malnutrition, only MP at 24 h was found to be independently associated. Only MPCRS at 1-4 and 24 h but not MP, MPBW, or MEBW at 24 h of diagnosing pARDS was significantly correlated with VFD-28. Conclusions: Normalization of MP is better related to outcomes and severity of pARDS than non-normalized MP. Malnutrition can be a significant confounding factor in resource-limited settings.

Aicardi-Goutières syndrome (AGS): recurrent fetal cardiomyopathy and pseudo-TORCH syndrome.

Aicardi-Goutières syndrome (AGS) induces innate immune activation. It can present with cerebral calcifications and hepatosplenomegaly mimicking congenital infections. The present case report discusses the diagnosis and treatment of a case of fetal cardiomyopathy whose postnatal symptoms resembled TORCH (toxoplasmosis, other agents, rubella, cytomegalovirus, herpes and syphilis) infection. The mother had a history of two lost pregnancies due to fetal cardiomyopathy and the same was identified in the current pregnancy. At 34 weeks of gestation, the mother delivered a late preterm male neonate due to intrauterine growth restriction weighing 1590 g with respiratory distress and cardiomyopathy at birth. The neonate had cerebral calcifications, hepatosplenomegaly and thrombocytopenia. As the infant's TORCH IgM titre was negative, pseudo-TORCH syndrome similar to AGS was suspected. Clinical exome sequencing of the parents and fetus identified no genes for hydrops fetalis or fetal cardiomyopathy; however, the AGS TREX1 gene was identified in the neonate, while additional symptoms resembled TORCH infection. The neonate was discharged and has shown improvement with oral baricitinib treatment for the last 9 months.

Diagnostic and Therapeutic Roles of the "Omics" in Hypoxic-Ischemic Encephalopathy in Neonates.

Perinatal asphyxia and neonatal encephalopathy remain major causes of neonatal mortality, despite the improved availability of diagnostic and therapeutic tools, contributing to neurological and intellectual disabilities worldwide. An approach using a combination of clinical data, neuroimaging, and biochemical parameters is the current strategy towards the improved diagnosis and prognosis of the outcome in neonatal hypoxic-ischemic encephalopathy (HIE) using bioengineering methods. Traditional biomarkers are of little use in this multifactorial and variable phenotype-presenting clinical condition. Novel systems of biology-based "omics" approaches (genomics, transcriptome proteomics, and metabolomics) may help to identify biomarkers associated with brain and other tissue injuries, predicting the disease severity in HIE. Biomarker studies using omics technologies will likely be a key feature of future neuroprotective treatment methods and will help to assess the successful treatment and long-term efficacy of the intervention. This article reviews the roles of different omics as biomarkers of HIE and outlines the existing knowledge of our current understanding of the clinical use of different omics molecules as novel neonatal brain injury biomarkers, which may lead to improved interventions related to the diagnostic and therapeutic aspects of HIE.

Cow's milk protein allergy in a neonate presenting with methaemoglobinaemia.

Cow's milk protein allergy (CMPA) is the most common food allergy in infants. A previously healthy neonate fed with infant formula presented diarrhoea, vomiting and respiratory distress with cyanosis. Investigations showed thrombocytosis and leucocytosis with lymphocyte predominance. To our surprise blood gas analysis showed metabolic acidosis and a high methaemoglobin level of 33% (normal range <3%). Clinical status, metabolic acidosis and methaemoglobin level returned to normal following fluid resuscitation and methylene blue administration. The neonate was later managed with breast feeding and elemental formula. CMPA was diagnosed based on history and clinical improvement after elemental formula. Although not common in CMPA, methaemoglobinaemia should be recognised as a differential diagnosis in a hypoxic infant with metabolic acidosis and diarrhoea as early recognition and treatment with methylene blue can save a child's life.

Human Milk-Derived Fortifier as Rescue Therapy in Very Preterm Infants Intolerant to Cow's Milk-Derived Fortifier.

This was a retrospective, descriptive study where human milk-derived fortifier (HMDF) was used to rescue infants intolerant to cow's milk-derived fortifier (CMDF). Rescue therapy was used for newborns with feed intolerance, systemic symptoms, or thrombocytosis. In a total of 412 very preterm infants (gestational age ≤ 32 wk) admitted to NICU during the study period, 14 infants met the rescue protocol inclusion criteria. The mean gestational age of these 14 infants was 29.2 ± 1.2 wk and birth weight was 1161 ± 201 g. All the infants who received rescue protocol by changing over to HMDF tolerated feeds well and showed a positive growth trend. Four infants had thrombocytosis, out of which 2 infants had elevated platelet count even with HMDF. Premature infants with intolerance to CMDF were effectively managed using HMDF as a rescue protocol. Infants tolerated HMDF well and showed positive growth trends till the discharge.

Hypoventilation and progressive encephalopathy in a neonate with MTHFR deficiency.

Methylenetetrahydrofolate reductase (MTHFR) deficiency is a rare autosomal recessive inherited inborn error of metabolism, which presents with various severity depending on the level of residual enzyme activity. In neonates, it can present with recurrent hypoventilation episodes, persistent encephalopathy with or without microcephaly. MTHFR deficiency also results in hyperhomocysteinemia, homocystinuria and hypomethionemia. We report a male neonate with severe MTHFR deficiency presenting to us on third week of life with progressive encephalopathy, microcephaly, seizures, central hypoventilation. There was similar history in the previous sibling. The patient's blood lactate, ammonia, tandem mass spectrometry for amino acids and acyl carnitine were normal. He remained encephalopathic with progressive increase in need of respiratory support in spite of supportive treatment and metabolic cocktail consisting of riboflavin, pyridoxine, coenzyme Q and carnitine. This neonate had novel homozygous mutation, which results in MTHFR deficiency. In newborn with hypoventilation or recurrent apnoea with encephalopathy and microcephaly, MTHFR deficiency should be considered as a differential diagnosis. Mutation study helps in confirming diagnosis; however, extended newborn metabolic screening with homocysteine level could help in early diagnosis of these cases.

Pasteurized Donor Human Milk Should Not Replace Mother's Own Milk in Preterm Neonates: A Quality Initiative Toward Decreasing the "PDHM Dependency".

Aim: Mother's own milk (MOM) is the preferred source of neonatal nutrition. Due to various challenges, mothers are often unable to provide exclusive MOM to neonates admitted in neonatal intensive care units (NICUs) and depend on pasteurized donor human milk (PDHM). The aim of this quality improvement (QI) initiative was to enable mothers to provide MOM and consequently decrease the "PDHM dependency." Methods: Neonates <32 weeks of gestation (n = 120) were included. A multidisciplinary team was formed, and a detailed root cause analysis was done to understand the cause of PDHM dependency during the observation phase (November 1 to December 15, 2019). Various evidence-based practices were planned, tested, and implemented through Plan-Do-Study-Act cycles during the intervention phase (December 16, 2019 to January 31, 2020). These were further strengthened and adopted as a unit culture during the maintenance phase (February 1 to July 31, 2020). Results from the observation and intervention phases were compared. Results: Within 6 weeks of QI interventions, the average proportion of MOM significantly increased from 74.4% to 93.5% (p = 0.0003), and the proportion of PDHM significantly decreased from 20.5% to 4.6% (p = 0.005). The proportion of MOM remained at 82.5% during the maintenance phase. There was a significant decrease in the number of days to reach full feeds and regain birth weight. Conclusions: Provision of PDHM from our newly functional milk bank led to a reduced drive to express MOM in mothers of NICU babies. Our QI project focused on various strategies to improve MOM feeding and reduce PDHM dependence.

Sirolimus in infants with congenital hyperinsulinism (CHI) - a single-centre experience.

Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycaemia in neonates and infants. Medical treatment includes the use of high concentrations of glucose and combinations of diazoxide, octreotide and glucagon. We report our experience of using sirolimus, a mammalian target of rapamycin (mTOR) inhibitor, in the treatment of CHI in seven newborns who are poorly responding to standard medical therapy. Majority (87%) of infants achieved euglycaemia using a combination of oral feeding and the addition of sirolimus to standard medical treatment. One infant who failed to achieve euglycaemia even after surgery managed successfully with sirolimus. Diagnosis was confirmed by genetics evaluation; in three infants, novel mutations were detected. Outcome and long-term follow-up of all cases are described.Conclusion: Sirolimus can be considered in treatment of CHI refractory to standard medical treatment or in cases unresponsive to surgical treatment. What is Known: • Congenital hyperinsulinism (CHI) or persistent hyperinsulinaemic hypoglycaemia of infancy (PHHI) associated with mutations such as the ABBC8 or KCNJ gene known to cause hypoglycaemia refractory to standard medical treatment such as diazoxide and octreotide and may need subtotal pancreatectomy (STP). • Sirolimus, a mammalian target of rapamycin (mTOR) inhibitor, was recently reported to be useful for refractory CHI cases with variable efficacy. What is New: • Our case series describes efficacy and safety of sirolimus in seven genetically proven refractory CHI cases with mainly neonatal presentation. All patients' follow-ups are described. • Out of seven infants, six infants responded well to sirolimus, and among these one infant who failed to respond to surgery (STP) also successfully managed with sirolimus. • It highlights the right patient selection and right dose to successfully manage these cases without much adverse effects.

Quality improvement initiative to decrease extrauterine growth restriction in preterm neonates.

BACKGROUND: Prevention of extrauterine growth restriction (EUGR) in preterm neonates is one of the biggest challenges to neonatologists. Lack of uniformity and inconsistency in nutrition practices are the most common causes. We started a quality improvement (QI) initiative with an intention to decrease the proportion of EUGR. METHODS: We performed prospective nonrandomized QI from May 2018 to July 2019. Ninety-six neonates (born at <32 weeks and/or <1.2 kg) were compared with 111 historical controls. A continuous feedback loop was maintained, and changes were analyzed as plan-do-study-actcycle. RESULTS: Although EUGR was lower after the intervention (93.7% vs 87.5%), this change was not statistically significant. However, other measures of in-hospital neonatal growth showed improvement, including median discharge weight percentile from 1% to 3% (P = .003). Median difference in the z-score for weight from birth to discharge also improved significantly from -1.84 to -1.65 (P = .04). Babies in the intervention group regained birth weight earlier (P = .005) and had better growth velocity (P = .0005). The feeding was started early (P < .0001), and these babies reached full feeds (P < .0001) earlier than the control cohort. CONCLUSION: Although our QI initiative failed to achieve a significant reduction in EUGR, it did achieve a significant improvement in discharge weight percentile and difference in the z-score for weight at birth and during discharge from hospital. There was a significant improvement in growth velocity and an early regaining of birth weight. The implementation of written nutrition practice guidelines facilitated improved outcomes.

Utility of Endotracheal Tube Cuff Pressure Monitoring in Mechanically Ventilated (MV) Children in Preventing Post-extubation Stridor (PES).

OBJECTIVE: To study if protocolized monitoring of endotracheal tube (ETT) cuff pressure every 6 hours is better than adjusting endotracheal tube cuff inflation by the only bedside clinical assessment. MATERIALS AND METHODS: This was a single-center prospective randomized controlled study done between July 1, 2017 and March 31, 2019. Children between 1 month and 18 years, intubated with cuffed ETT by our trained doctors were included. After obtaining consent, patients were randomized into two groups, standard group (SG) and cuff pressure monitoring group (MG). Sample size was calculated with 80 patients in each group with a power of 80%, significance level (alpha 0.05 and beta 0.2). In the SG, ETT cuff inflation was adjusted by clinical assessment (bedside minimal leak technique and monitoring the percentage of leak displayed on ventilator display) at 6 hours interval. In the MG, cuff pressures were monitored by the device every 6 hours to maintain between 20 and 25 mm Hg. RESULTS: Out of 543 mechanically ventilated children during the study period, 266 were eligible and randomized for study. During the study, 89 patients died and 17 were left against medical advice, leaving 80 patients in each group. Incidence of post-extubation stridor (PES), re-intubation rate, ventilator-associated pneumonia (VAP) rate, ventilator days, and length of pediatric intensive care unit (PICU) stay were analyzed and found no advantage of protocolized monitoring of cuff pressures in the reduction of any of the above variables. CONCLUSION: Our findings if confirmed by large multicentric studies can bring an end to routine ETT cuff pressure measurements and emphasize more on clinical assessment.

Thiamine-Responsive Acute Pulmonary Hypertension of Early Infancy (TRAPHEI)-A Case Series and Clinical Review.

Persistent pulmonary hypertension of the newborn (PPHN) is a syndrome of high pulmonary vascular resistance (PVR) commonly seen all over the world in the immediate newborn period. Several case reports from India have recently described severe pulmonary hypertension among infants in the postneonatal period. These cases typically present with respiratory distress in 1-6-month-old infants, breastfed by mothers on a polished rice-based diet. Predisposing factors include respiratory tract infection such as acute laryngotracheobronchitis with change in voice, leading to pulmonary hypertension, right atrial and ventricular dilation, pulmonary edema and hepatomegaly. Mortality is high without specific therapy. Respiratory support, pulmonary vasodilator therapy, inotropes, diuretics and thiamine infusion have improved the outcome of these infants. This review outlines four typical patients with thiamine-responsive acute pulmonary hypertension of early infancy (TRAPHEI) due to thiamine deficiency and discusses pathophysiology, clinical features, diagnostic criteria and therapeutic options.

A Quality Initiative to Improve Mother's Own Milk Feeding in Preterm Neonates.

Background: The rates of "any" human milk use in neonatal intensive care units have improved during the last decade. However, efforts to help mothers in expressing and maintaining mother's own milk (MOM) through discharge remain a concern. This study aims to improve MOM in preterm neonates. Methods: The study was a quality improvement (QI) initiative conducted from May 2018 to April 2019. All preterm neonates <34 weeks were included. In the "initiation phase" (May 2018 to August 2018), a breastfeeding support group was formed and mothers were given structured antenatal and postnatal counseling regarding MOM using videos and leaflets. This improved MOM rates when compared with retrospective controls. In the continuation phase (August-2018 to April-2019), various plan-do-study-act cycles were conducted to test strategies such as frequent telephonic reminders, standardization of Kangaroo mother care, nonnutritive sucking protocols, and involving family members during daily counseling sessions. The initiation and continuation phases were compared with the retrospective baseline data. Results: Of a total of 125 preterm neonates, 27 were excluded for various reasons. Within 3 months of initiating the study, the proportion of neonates who received MOM within first 24 hours improved from 24% in retrospective controls to 82.9% in the initiation phase (p < 0.0001) and remained stable at 90.3% in the continuation phase. The amount of MOM received on day 1 increased significantly (p < 0.0001) from a median of 0 mL to 1 mL in the initiation phase and was maintained at 3 mL in the continuation phase. Amount of MOM increased significantly on day 3 (p = 0.0003) and day 7 (p = 0.03). Babies discharged on MOM also improved significantly (p = 0.005) from 48.3% in the retrospective cohort to 77.4% in the continuation phase. The number of babies receiving total parenteral nutrition decreased significantly (p = 0.02) from 54.6% to 26.7%. Conclusions: QI has shown promising results in improving MOM in preterm neonates.

Perinatal-Neonatal Management of COVID-19 Infection: guidelines of the Federation of Obstetric and Gynaecological Societies of India (FOGSI), National Neonatology Forum of India (NNF), and Indian Academy of Pediatrics (IAP)

During the current rapidly evolving pandemic of COVID-19 infection, pregnant women with suspected or confirmed COVID-19 and their newborn infants form a special vulnerable group that needs immediate attention. Unlike other elective medical and surgical problems for which care can be deferred during the pandemic, pregnancies and childbirths continue. Perinatal period poses unique challenges and care of the mother-baby dyads requires special resources for prevention of transmission, diagnosis of infection and providing clinical care during labor, resuscitation and postnatal period. Process: The GRADE approach recommended by the World Health Organization was used to develop the guideline. A Guideline Development Group (GDG) comprising of obstetricians, neonatologists and pediatricians was constituted. The GDG drafted a list of questions which are likely to be faced by clinicians involved in obstetric and neonatal care. An e-survey was carried out amongst a wider group of clinicians to invite more questions and prioritize. Literature search was carried out in PubMed and websites of relevant international and national professional organizations. Existing guidelines, systematic reviews, clinical trials, narrative reviews and other descriptive reports were reviewed. For the practicequestions, the evidence was extracted into evidence profiles. The context, resources required, values and preferences were considered for developing the recommendations. Objectives: To provide recommendations for prevention of transmission, diagnosis of infection and providing clinical care during labor, resuscitation and postnatal period. Recommendations: A set of twenty recommendations are provided under the following broad headings: 1) pregnant women with travel history, clinical suspicion or confirmed COVID-19 infection; 2) neonatal care; 3) prevention and infection control; 4) diagnosis; 5) general questions.

Mitochondrial carbonic anhydrase VA deficiency in three Indian infants manifesting early metabolic crisis.

BACKGROUND: Hyperammonemia and hyperlactatemia in neonates and young children with non-specific biochemical markers poses a diagnostic challenge. An accurate diagnosis is essential for effective management. CASE REPORTS: We present three infants from unrelated families, one with infantile and two with neonatal hyperammonemic encephalopathy, hypoglycaemia, and hyperlactatemia. The underlying cause was confirmed following whole exome sequencing as biochemical markers were not conclusive of a definite diagnosis. CONCLUSION: The combination of hyperammonemic encephalopathy, hyperlactatemia and hypoglycemia in neonates and infants should prompt physicians to suspect Carbonic anhydrase VA deficiency. Majority of these children can have a favourable long-term outcome with symptomatic treatment.

A quality initiative to improve exclusive breast milk feeding in preterm neonates.

BACKGROUND AND OBJECTIVE: Preterm babies thrive well on exclusive breastfeeding with fewer complications. In a retrospective analysis, challenges were noticed in the form of delayed first milk expression and frequency of expression, which was limited to 2-3 times a day. A quality improvement initiative was designed to increase the exclusive breast milk feeding rates in admitted preterm babies. The purpose of the present study is to evaluate the proportion of preterm neonates receiving mother's own milk by day 7 of life after such an initiative. METHODS: The quality improvement initiative was conducted at a level 3 neonatal intensive care unit from May 10, 2018, to August 10, 2018. Inborn preterm neonates <34 weeks with a minimum hospital stay of 7 days were included. Neonates of critically sick mothers and neonates having major congenital malformations were excluded. Mothers were given structured antenatal counseling regarding expressing breast milk (EBM). Postnatal visits were conducted to provide information through a video and a leaflet and formation of breastfeeding support group. RESULTS: A total of 30 babies were recruited during a period of 3 months and compared to historical controls. The median age of the first EBM improved from 2.5 days to 1.16 days, and the amount of EBM on the first day improved from 0.24 ml to 2.6 ml (p = .002). The proportion of babies receiving EBM on the first day improved from 24% to 80% (p = .0001), and at the end of 7 days, it increased to 73% from 46% (p = .02). The factors time to reach full enteral feeds, time to regain birth weight, rate of necrotizing enterocolitis, rate of sepsis, and proportion of babies on exclusive mother's milk during discharge appear comparable in both the groups. CONCLUSIONS: A simple quality improvement approach through the formation of breastfeeding support group, antenatal counseling, and postnatal support for breast milk expression has made a significant improvement in milk expression from mothers delivered prematurely. It reflects on a team approach using the available resources.

Antimicrobial Justification form for Restricting Antibiotic Use in a Pediatric Intensive Care Unit.

OBJECTIVE: To study whether introduction of an antimicrobial justification form deters clinicians from prescribing restricted antimicrobials and results in de-escalation of these antimicrobials. METHODS: Clinicians were asked to fill a justification form if prescribing an antimicrobial from the pre-identified restricted group. Antimicrobial usage pattern over next year was compared with that in the one year preceding the introduction of justification form. RESULTS: Significant overall decrease in antimicrobial usage (40.5% vs 34.6%) was noted in the post-intervention group along with a significant increase in the de-escalation of antibiotics. CONCLUSION: Introduction of a justification form before prescribing antimicrobials or at the time of deferring de-escalation can be useful in restricting usage of antimicrobials.

Papaverine for Ischemia Following Peripheral Arterial Catheterization in Neonates.

11 Extremely low birth weight neonates who developed skin discoloration after peripheral arterial catheterization were given intra-arterial papaverine before the removal of arterial line. The skin color turned normal in all these neonates and none developed residual damage. In 3 neonates who could not receive papaverine, one developed gangrene of fingers.
