Neonatal mortality among disaggregated Asian American and Native Hawaiian/Pacific Islander populations.

We compared neonatal (<28 days) mortality rates (NMRs) across disaggregated Asian American and Native Hawaiian/Pacific Islander (AANHPI) groups using recent, national data. We used 2015-2019 cohort-linked birth-infant death records from the National Vital Statistics System. Our sample included 61,703 neonatal deaths among 18,709,743 births across all racial and ethnic groups. We compared unadjusted NMRs across disaggregated AANHPI groups, then compared NMRs adjusting for maternal sociodemographic, maternalclinical, and neonatal risk factors. Unadjusted NMRs differed by over 3-fold amongst disaggregated AANHPI groups. Native Hawaiian/Pacific Islander neonates in aggregate had the highest fully-adjusted odds of mortality (OR: 1.08 [95% CI: 0.89, 1.31]) compared to non-Hispanic White neonates. Filipino, Asian Indian, and Other Asian neonates experienced significant decreases in odds ratios after adjusting for neonatal risk factors. Aggregating AANHPI neonates masks large heterogeneity and undermines opportunities to provide targeted care to higher-risk groups.

Nomograms and Reference Ranges for Intra-Cranial Ventricular Dimensions in Indian Neonates.

To establish normal reference values for commonly used ventricular indices - Anterior Horn Width (AHW), Ventricular Index (VI) and Thalamo-Occipital Distance (TOD)-against common variables including gestational age, birth weight and head circumference in Indian newborns. This was a cross-sectional study. Cranial ultrasound was performed between post-natal days 3 to 7. Anterior fontanelle was taken as the acoustic window. Data were analyzed to determine correlation, coefficient of determination (R2), regression equations and plotted against gestational age (GA). Total 2200 newborns were included in the study.The study observed that there is an increase in VI, AHWand TODwith an increase in gestational age (p-value < 0.001) and birth weight (p-value < 0.001). No significant correlation of gender and singleton or multiple gestation-with the intraventricular dimensions was observed (p-value > 0.05). All the three ventricular parameters were found to have a significantly lower mean value in the normal vaginal delivery group as compared to the LSCS group. There was a good correlation between ventricular indices of the left and right side. Nomograms of AHW, TOD, and VI were prepared with respect to gestational age. Intracranial ventricular size dimensions vary significantly with increasing gestational age and birth weight. The new nomograms for various ventricular indices of Indian neonates can assist in objectively assessing ventricular sizes.

Biological Reference Intervals for 17α-Hydroxyprogesterone Immunoreactive Trypsinogen, and Biotinidase in Indian Newborns

Neonatal deaths, which usually occur in the first week after delivery, account for nearly 75 percent of all deaths of children under 5 years of age. Prematurity, birth difficulties, infections, and birth defects are responsible for about 40 percent of these deaths. Although mortality rates have declined since 2000, access to quality healthcare remains a major problem for mothers and infants worldwide. In perspective, the present study aimed to establish clear biological reference intervals for 17α-hydroxyprogesterone (17-OHP), immunoreactive trypsinogen (IRT), and biotinidase in Indian neonates. The statistical analysis of data from up to 3200 dried blood spot (DBS) samples of Indian newborns provided valuable information for the new cut-off values in newborn screening (NBS) programs. We applied correlation analysis to fix the relationship for NBS parameters such as 17-OHP, IRT, and biotinidase. This study provided important information about the distribution and comparison of key cut-offs for biomarkers considering body weights and gestational age in the Indian newborn population for the first time, which can help healthcare experts make easier treatment decisions.

Applicability of the External Genitalia Score (EGS) in Indian neonates and children up to 2 years of age.

To generate normative data and validate the recently developed, gender-neutral, External Genitalia Score (EGS) in Indian preterm and term neonates and children up to 2 years of age with normal and atypical genitalia. This observational study included 1,040 neonates born between 28 and 42weeks of gestation and 152 children between 1 and 24months of age. In addition, 50 children with disorders of sex development (DSD) were also enrolled in the study. The Prader stage/external masculinization score (EMS) (as applicable), anogenital ratio (AGR) and EGS were assessed for all neonates and children with typical and atypical genitalia. Median EGS values in newborn males with typical genitalia were 9.5 at 28-31weeks, 10.5 at 32-33weeks, 11 at 34weeks and 11.5 in males at 35-42weeks of gestation. For all females with typical genitalia, the EGS was 0. EMS and EGS showed a positive correlation in males with typical genitalia (r=0.421, p=0.000**) and all children with DSD (r=0.857, p=0.000**). Mean AGR in males and females with typical genitalia and those with DSD were 0.52±0.07, 0.31±0.05 and 0.47±0.13, respectively. EGS correlated with AGR in all males with typical genitalia (r=0.107, p=0.008**), and in all children with DSD (r=0.473, p=0.001**). The EGS enables accurate, gender-neutral and comprehensive assessment of external genitalia in Indian neonates and children with typical and atypical genitalia/DSD. Evaluation for DSD is recommended in any child with EGS greater than 0 and≤10th percentile for gestation or age (10.5 in a term neonate).

Lung ultrasound for prediction of surfactant requirement in Indian preterm neonates: a diagnostic accuracy study.

Surfactant replacement for respiratory distress syndrome (RDS) is currently guided by oxygen (FiO2) requirement in preterm neonates. Lung ultrasound (LUS) has emerged as an important predictive tool; however, there is a paucity of evidence from developing countries.The objective of this study was to determine the diagnostic accuracy of the LUS score in comparison to standard criteria based on FiO2 requirement for prediction of surfactant requirement.In this prospective study, preterm neonates of < 34 weeks' gestation with RDS were included within 2 h of life. Surfactant was administered if the FiO2 requirement exceeded 30%. Baseline characteristics, respiratory parameters, and LUS clips were recorded soon after birth and compared between the surfactant and non-surfactant groups. LUS scoring was later performed by masked assessors which was not used in the management of neonates.Among 82 neonates (mean gestation 30.6 weeks and weight 1375 g) included in the study, 33 (40.2%) received surfactant. The surfactant group had a higher Silverman score, required higher FiO2 and mean airway pressure, and needed invasive ventilation more frequently. The mean (± SD) LUS score was significantly higher in the surfactant (9.4 ± 3.2) compared to the non-surfactant group (5.1 ± 2.1). The diagnostic accuracy of LUS scoring was determined by ROC curve analysis (AUC (95% CI): 0.83 (0.74-0.92), p < 0.01). A cutoff score of ≥ 8 for LUS was considered optimal for the prediction of surfactant requirement (sensitivity and specificity (95% CI) of 70% (51-84) and 80% (66-90), respectively). Conclusion:Lung ultrasound is a valid diagnostic tool for the prediction of surfactant requirements in resource-limited settings. What is Known: • Lung ultrasound has a good diagnostic accuracy in predicting the need for surfactant administration in preterm neonates in developed countries, but its role in developing countries is unclear. What is New: • Lung ultrasound proved to be a valid diagnostic tool in predicting surfactant replacement therapy in resource-limited settings. • The diagnostic performance of lung ultrasound was better in neonates on non-invasive ventilation, compared to invasive ventilation.

Immune profiling reveals umbilical cord blood mononuclear cells from South India display an IL-8 dominant, CXCL-10 deficient polyfunctional monocyte response to pathogen-associated molecular patterns that is distinct from adult blood cells.

Neonate responses to pathogen-associated molecular patterns (PAMPS) differ from adults; such understanding is poor in Indian neonates, despite recognized significant infectious risk. Immune profiling analysis was undertaken of 10 secreted mediators contextualized with cellular source induced by six PAMPs in umbilical cord (CB; n = 21) and adult-blood (PBMC; n = 14) from a tertiary care hospital in South India. Differential cytokine expression analysis (minimum log2-fold difference; adj P-value < 0.05) identified bacterial PAMPs induced higher concentrations of IL-1β, IL-10, TNF-α in adults versus IL-8, GM-CSF, IFN-γ, and IL-2 in CB. CB responded to poly I:C and SARS-CoV-2 lysate with a dominant IL-8 response, whereas in PBMC, CXCL-10 dominated poly I:C, but not SARS-CoV-2, responses, highlighting potential IL-8 importance, in the absence of Type I Interferons, in antiviral CB immunity. Candida albicans was the only PAMP to uniformly induce higher secretion of effectors in CB. The predominant source of IL-8/IL-6/TNF-α/IL-1β in both CB and PBMC was polyfunctional monocytes and IFN-γ/IL-2/IL-17 from innate lymphocytes. Correlation matrix analyses revealed IL-8 to be the most differentially regulated, correlating positively in CB versus negatively in PBMC with IL-6, GM-CSF, IFN-γ, IL-2, consistent with more negatively regulated cytokine modules in adults, potentially linked to higher anti-inflammatory IL-10. Cord and adult blood from India respond robustly to PAMPs with unique effector combinations. These data provide a strong foundation to monitor, explore, mechanisms that regulate such immunity during the life course, an area of significant global health importance given infection-related infant mortality incidence.

Confluence of newborn's sex and their mother's characteristics resulting in fetal macrosomia among Indian neonates

BackgroundA newborn's birth weight ≥4000 g is defined as fetal macrosomia, which is recognized as a reproductive and serious child health concern. ObjectivesOur study aims to reveal existence of any connection between maternal factors and newborn sex in giving birth to newborn ≥4000 g in an Indian context. MethodsData were drawn from the fifth round of National Family Health Survey (NFHS-5). A cross-sectional observational study was carried out with a total of 152,827 children born to women in reproductive age group (15–49) who had most recent live birth in the five years preceding the survey. Descriptive analyses, cross-tabulation, test of association and multivariate logistic regression analyses were performed. ResultsIn India, the prevalence of macrosomia was found in 3.8% of the total study participants. Considering newborn characteristics, fetal macrosomia was more prevalent among male neonates than female (AOR: 0.730; 95% CI: 0.687–0.775). Regarding maternal characteristics, overweight (AOR: 1.468; 95% CI: 2.042–2.559) and obese (AOR: 2.764; 95% CI: 2.394–3.192) motherswith gestational diabetes (AOR: 1.731, 95% CI: 1.385–2.164) and hypertension (AOR: 1.288, 95% CI: 1.116–1.488) were more likely to giving birth of macrosomic babies. Multiparous mothers (AOR: 1.207, 95% CI: 1.128–1.293) and women who did not undergo proper antenatal care (ANC) follow up had also greater risk of developing fetal macrosomia. Muslim women (AOR: 1.223, 95% CI: 1.119–1.338), and women belonging to a tribe (AOR: 1.476, 95% CI: 0.922–2.361) were significantly associated with the risk of having newborn ≥4000 g. ConclusionEmphasis should be given on counseling for mothers for desired weight management before and during pregnancy, gestational diabetes and hypertension screening, physical activity during pregnancy, adequate ANC follow up and balanced dietary intake among pregnant women.

Rare Occurrence DNAJB4 Gene Mutation Leads To Early Respiratory Failure In An Indian Neonate

Rare Occurrence DNAJB4 Gene Mutation Leads To Early Respiratory Failure In An Indian Neonate

Generation of South Indian Data for Normal Clitoral Dimensions and Anogenital Ratio in Term Neonates.

Assessment of genitalia is an important part of the neonatal examination. Regional, racial, and ethnic variations in phallic length have been documented. Clitoral dimensions may also show similar variations. Normal values for neonatal clitoral measurements may help the pediatrician/neonatologist to accurately diagnose clitoromegaly and underlying etiology to guide appropriate investigations. Data on clitoral measurements is limited with only one study from India (Kolkata). Hence we aimed in this study to generate south Indian data on neonatal clitoral dimensions, anogenital distance, and anogenital ratio. Two hundred and fifty two hemodynamically stable term female neonates without ambiguous genitalia/vulval masses born in a community hospital. Hospital-based cross-sectional study. 1. To measure clitoral dimensions, anogenital distance, and anogenital ratio in female neonates. 2. To correlate clitoral dimensions, anogenital distance, and ratio with anthropometric measurements, gestational age, and maternal comorbidities. Measurements were recorded using a digital vernier caliper, under strict aseptic precautions with labia majora gently separated and the baby held in a frog-leg position. Clitoral length, width, and anogenital distance were measured and anogenital ratio and clitoral index were calculated. In term neonates, the mean ± SD of clitoral length (CL), clitoral width (CW), anogenital ratio (AGR) were 6.34 ± 1.75 mm, 6.39 ± 1.27 mm and 0.39 ± 0.05, respectively. The 3rd and 97th centiles for mean clitoral length were 3.55 and 9.93 mm, for mean clitoral width were 3.37 and 8.35 mm, and for AGR were 0.28 and 0.48, respectively. These clitoral dimensions in south Indian neonates were higher than those from East India (Kolkata), lower than Nigerian babies, and similar to Israeli neonates. Mean CL and CW had no statistical correlation with birth weight, gestational age, head circumference, or length in term neonates. A significant correlation was noted between pregnancy-induced hypertension and mean clitoral width, and between gestational diabetes and AGR. Normative values for clitoral dimensions (length and width) and AGR for south Indian term female neonates have been established. 97th centiles of 9.93 mm (CL) and 8.35 mm (CW) and 0.48 mm (AGR) may be used as practical cut-offs to diagnose clitoromegaly and virilization. Clitoral measurements had no statistical correlation with birth weight, gestational age, or anthropometry. Clitoral measurements exhibit ethnic and racial differences, thus emphasizing the importance of regional cut-offs and need for more studies from different parts of India on CL.

Profiling non-nutritive sucking skills in full-term and preterm neonates

BackgroundNon-nutritive sucking (NNS) is a reflex in neonates where they suck on objects without receiving food. It aids in oral development and self-regulation. Preterm birth can affect NNS and feeding. Based on current guidelines, early evaluation is crucial for identifying any delay in normal development in this population. Hence, the current study aims to profile non-nutritive sucking skills in full-term (37 to < 42 weeks) and preterm (32 to < 37 weeks) neonates and to compare non-nutritive sucking skills between the groups.MethodA total of 180 neonates completed this study. “The test for oropharyngeal dysphagia in Indian neonates” (TOD-IN) was used to profile non-nutritive sucking. The number of sucks, swallows, bursts, duration of sucking, suck/le per swallow, and pause duration was also assessed.ResultsThere was a statistically significant difference between the groups for non-nutritive sucking at p = < .001 and Cohen’s d had a large effect size (d = 1.42). Preterm neonates had a lesser number of sucks, bursts, swallows, and duration of sucking but had a higher pause duration compared to full-term neonates.ConclusionNon-nutritive sucking skills develop with advancing postmenstrual age and a detailed profile is imperative for a proper assessment to identify progress and delays.

Methylation Status of IGF-Axis Genes in the Placenta of South Indian Neonates with Appropriate and Small for Gestational Age

Objective Altered methylation patterns of insulin-like growth factor (IGF)-axis genes in small for gestational age (SGA) have been reported in different populations. In the present study, we analyzed the methylation status of IGF-axis genes in the placenta of appropriate for gestational age (AGA) and SGA neonates of South Indian women. Methods Placental samples were collected from AGA (n = 40) and SAG (n = 40) neonates. The methylation of IGF-axis genes promoter was analyzed using MS-PCR. Results IGF2, H19, IGF1, and IGFR1 genes promoter methylation was 2.5, 1.5, 5, and 7.5% lower in SGA compared to AGA, respectively. Co-methylation of IGF-axis genes promoter was 40% and 20% in AGA and SGA, respectively. IGF-axis gene promoter methylation significantly (p < 0.05) influenced the levels of IGFBP3 protein, birth weight, mitotic index, gestational weeks, and IGFR1 and IGFR2 gene expression. Conclusion IGF-axis genes methylation was lower in SGA than in AGA, and the methylation significantly influenced the IGF-axis components.

Four-hour voiding observation: Normative data from term Indian neonates

BackgroundThe four-hour voiding observation is an important non-invasive urodynamic test for infants and young children before toilet training. The study was performed to generate normative data for term Indian neonates. MethodsThe study was a descriptive study performed in the Department of Paediatrics of a secondary care hospital in South India with patients having nationwide representation from August 2018 to August 2020. Term neonates, appropriate for gestational age on days 4–14 of life were included. Neonates at risk of oliguria or abnormal bladder functions were excluded. Four-hour voiding observation was performed by direct observation of voids, pre- and post-void diaper weight and measurement of post-void residue (PVR) by ultrasonography using two formulae within five minutes of voiding. ResultsA total of 102 neonates (166 voids) were studied. Important results were (a) Eight neonates did not void; (b) median (fifth–95th percentile) of important test outcomes as follows: voided volume: 15 (7.5–33.5) ml, maximum voided volume (MVV) 16.5 (8.0–38.7) ml, PVR 3.2 (0.5–10.2) ml, PVR% 17.0 (2.9–46.4) % functional bladder capacity 19.7 (9.6–38.0) ml, and diuresis: 1.7 (0.0–5.1) ml/kg/hour; (c) four (4.3%) neonates had one interrupted void each; (d) linear regression yielded the following formulae: MVV (ml) = 8.1019 + 4.8702 ∗Diuresis (ml/kg/hr) and PVR % (max) = 14.2312 + 3.2682∗ Diuresis (ml/kg/hr). ConclusionNormative data on the four-hour voiding observation study for Indian term exclusively breast-fed neonates are reported.

Early Myoclonic Infantile Encephalopathy in Neonate Caused by 5-Oxoprolinuria, a Rare Metabolic Entity: A Case Report

Neonatal encephalopathy is a common entity encountered by treating physicians in any neonatal intensive care unit. Though hypoxic ischaemic encephalopathy is the most frequent cause in developing countries, metabolic causes should also be looked for in refractory neonatal seizures with sibling death and parental consanguinity. Early myoclonic infantile encephalopathy, considered under the broad spectrum of infantile encephalopathy, is a rare syndrome in infants with onset within 3 months of age. It is characterized by myoclonic seizures, features of encephalopathy and caused by underlying metabolic diseases, nonketotic hyperglycinemia being the most common cause. On contrary its close mimicker, Ohtahara syndrome or early infantile epileptic encephalopathy is most likely associated with structural neurological lesions. We report a 12-day term Indian male neonate, born of second degree consanguinity with multiple sibling death history, presented with refractory myoclonic seizures in spite of uneventful birth history. Myoclonic seizures, refractory to intravenous phenobarbitone, phenytoin and infusion Midazolam, persisted after ruling out hypoglycemia, dyselectrolytemia, and neonatal sepsis. EEG showed typical burst suppression pattern pointing towards diagnosis of early myoclonic infantile encephalopathy. Further metabolic causes were looked for but tandem mass spectrometry for dried blood sample was normal. Lastly, urinary GCMS revealed 5-oxoprolinuria, an autosomal recessive condition, characterized by acidosis, jaundice, and severe hemolytic anemia among neonates, primarily due to glutathione synthetase enzyme deficiency. In severe form of 5-oxoprolinuria, neurological complications in form of seizures, ataxia have been documented in earlier studies; however, its association with myoclonic encephalopathy is yet to be reported in the literature and this report may be the first of its kind.

Echocardiographic nomograms and Z-scores for term Indian neonates.

The availability of nomograms is crucial for the correct interpretation of pediatric and neonatal echocardiograms. Echocardiographic Z-score applications/websites use Western nomograms as reference, which may not be an appropriate standard for gauging Indian neonates. Currently available Indian pediatric nomograms either have not included neonates or have not been specifically designed for neonates. This gross underrepresentation of neonates renders available nomograms unreliable for use as standards for comparison. The objective of this study was to collect normative data for the measurement of various cardiac structures using M-Mode and two-dimensional (2D) echo in healthy Indian neonates and to derive Z-scores for each measured parameter. Echocardiograms were performed on healthy term neonates (within first 5 days of life). Birth weight and length were recorded, and body surface area was calculated using Haycock's formula. Twenty M-mode and 2D-echo parameters were measured (including left ventricular dimensions, atrioventricular valves, and semilunar valves' annuli sizes, pulmonary artery and branches, aortic root, and arch). We studied 142 neonates (73 males) with a mean age of 1.83 ± 1.12 days and mean birth weight of 2.89 ± 0.39 Kg. Regression equations with linear, logarithmic, exponential and square root models were tested to select the best model of fit for the relationship between birth weight and each echocardiographic parameter. Scatter plots and nomogram charts with Z-scores were prepared for each echocardiographic parameter. Our study provides nomograms with Z-scores for term Indian neonates weighing between 2 kg and 4 kg at birth, within first 5 days of life, for a set of echocardiographic parameters that are frequently used in clinical practice. This nomogram has poor predictability for babies at extremes of birth weight. There is a need for further indigenous studies to include neonates at extremes of weight, both term, and preterm.

Nasal Anthropometry among Term and Preterm Indian Neonates- Does Size Matter?

Introduction: The binasal prongs are used in neonatal intensive care unit (NICU) to provide nasal Continuous Positive Airway Pressure (n-CPAP) in preterm neonates. A variable degree of nasal trauma is the most common complication of n-CPAP therapy. This can be reduced by use of appropriately sized binasal prongs that are customized to the anatomical measurements of noses. The aim was to estimate the nasal two-dimensional anthropometrical parameters among Indian neonates across different gestations; to compare between both sexes and between neonates with different intra uterine growth status and gestational ages. Methods: Hundred and one neonates across different gestational ages (24 – 42 weeks) and intrauterine growth status who were admitted to the NICU of a tertiary teaching hospital were enrolled and grouped into five categories based on their gestational ages viz. 37 – 42 weeks, 34 – 36 weeks, 31 – 33 weeks, 28 – 30 weeks, and 24 – 27 weeks. Seven nasal and para-nasal measurements were taken (nostril width, nostril length, columella width, columella length, nose width, nose length and philtrum length) for each neonate using a vernier caliper. Results: All anthropometrical measurements differed significantly across gestations especially between 37 - 42 and 24 - 27 wks (p = 0.00). Males differed from females only with respect to nostril width (p = 0.032). The measurements varied significantly when compared among small for gestational age, appropriate for gestational age and large for gestational age neonates. Conclusions: The nasal parameters differed significantly among various GA and intra-uterine growth statuses, which should help design appropriate sizes of bi-nasal prongs.

577. Cord Blood Protective Antibodies Seroprevalence against Diphtheria, Pertussis, Measles, Mumps and Rubella at Birth among Healthy Term Indian Neonates

Abstract Background The resurgence of vaccine preventable diseases in young infants is a matter of concern worldwide. Cord blood antibodies seroprevalence against various vaccine preventable diseases could reflect protection rates among adults, which could be important in providing protection in early infancy of newborn baby. Tdap vaccination is not yet part of immunization program for pregnant women in India. Methods Apparently healthy term newborns, delivered at a tertiary care hospital in Northern India, over two-year period were enrolled after taking informed written consent from their parents, and their cord blood sample was collected at birth. Ethical clearance was obtained from Institute Ethics Committee before starting enrollment. Results A total of 160 newborns (M:F=86:74) were enrolled. In our study, antibodies (IgG) against diphtheria toxin (DT) were &amp;gt;0.1 IU/ml in 44.4% (71/160), 0.01 to 0.1 IU/ml in 53.1% (85/160) and &amp;lt; 0.01 IU/ml in 2.5% (4/160). Only 44.4% of them were fully protected at birth against diphtheria. Antibodies (IgG) against pertussis toxin (PT) &amp;gt;40 U/ml were seen in 41.2% (66/160). Out of these 66 children, 23 had titers &amp;gt;100 U/ml. Total of 58.8% (94/160) children had antibodies &amp;lt; 40 U/ml. Out of these 94 children, 48 had titers &amp;lt; 20 U/ml. Since correlates of protection in pertussis are not defined; those having titers &amp;gt;100 U/ml i.e. 14.3% were most protected; while those having titers &amp;lt; 20 U/ml were least protected. Antibodies (IgG) against measles antigen were &amp;gt;12 IU/ml in 88.8% (142/160). Antibodies (IgG) against mumps antigen were &amp;gt;12 IU/ml in 83.1% (133/160). Antibodies (IgG) against rubella antigen were &amp;gt;12 IU/ml in 83.7% (134/160). Conclusion Protective antibodies against diphtheria and pertussis toxins were less in the studied newborns at birth making them susceptible to these diseases in early infancy, before primary vaccination commences. Tdap vaccination for pregnant mothers in India could help in improving these titers and protection in early infancy. Protective antibodies against measles, mumps and rubella in studied newborns at birth were satisfactory. For further enhancing protection, especially against rubella, one dose of MMR vaccine may be advised for women in child bearing age.

Gestational Age-Specific Nomogram of Transcutaneous Bilirubin in First 120 h of Life for Term and Late Preterm Indian Neonates

To create a nomogram based on transcutaneous bilirubin values (TCB) in first week of life for term and late preterm (>34 weeks) neonates. Prospective longitudinal study. Four tertiary-care teaching hospitals (one each in eastern and southern India, two in northern India) between February 2019 and March 2020. A total of 2492 term and late preterm (>34 weeks) neonates. Bilirubin was measured by transcutaneous bilirubinometer (Drager JM-105, Germany) in all neonates in pre-specified times of the day, 12 hourly every day since birth till discharge between 48 and 72 h, and data were recorded in epochs of 6 hourly intervals. Post-discharge, all neonates were called for review in next 48 h. Primary-TCB in first week of life. Secondary-factors having significant association with significant hyperbilirubinaemia requiring phototherapy. Total of 2492 neonates (males 1303 and female 1189), with a total of 14162 TCB recordings were analysed and mean hourly bilirubin (TCB) at hourly intervals till 120 h and then daily bilirubin values on Days 6 and 7 were tabulated. We have constructed hour-specific bilirubin nomogram with percentiles as per gestational age in term and near-term Indian neonates till 120 h of life. Amongst the known risk factors, delayed cord clamping, primipara and breastfeeding jaundice had significant association for hyperbilirubinaemia needing phototherapy. We have created gestation-specific nomogram of TCB levels in 6 hourly intervals for the first 120 postnatal hours, obtained from a large predominantly breast fed healthy, term and near-term Indian neonates.
