Gestational Age Specific Postnatal Growth Curves for Singleton Babies in Tertiary Hospital of Western Nepal
Introduction: Measurement of birth weight (BW), crown heel length (CHL), head circumference (HC) and chest circumference used to assess the intrauterine growth of a baby vary with altitude, race, gender, socio economic status, maternal size, and maternal diseases. The study aimed to construct centile charts for BW, CHL and HC for new born at different gestational ages in western Nepal.
Methods: This was a descriptive cross sectional study done over a period of 15 months in a tertiary care hospital of western Nepal. BW, length, HC and CC were measured within 12-24 hours of birth. Gestational age was estimated from first day of last menstrual period, maternal ultrasonology and New Ballard’s scoring system. Microsoft 2007 Excel and SPSS-16 was used for data analysis. Cole’s Lambda Mu Sigma method was used for constructing centile curves.
Results: Out of 2000 babies analysed, 1910 samples were used to construct smoothed intrauterine growth curve of BW, CHL, and HC from 33-42 weeks of gestation. 57.35% (1147) were male, mean gestational age was 38.13 ±2.44 weeks, where 21.5% were preterm and 1.7% post term. The means of BW, CHL, HC and CC were 2744.78 gm, 47.80 cm, 33.18 cm, and 30.20 cm with standard deviations of 528.29, 3.124, 1.78, and 2.35 respectively. These data vary as compared to the Kathmandu data, in case of birth weight for 10th and 90th centiles, and at 90th centile in case of length.
Conclusions: This necessitates the update in the existing growth charts and develop in different geographical regions of a country
Device-independent randomness certification using multiple copies of entangled states
We demonstrate to what extent many copies of maximally entangled two-qubit states enable for generating a greater amount of certified randomness than that can be certified from a single copy. Although it appears that greater the dimension of the system implies a higher amount of randomness, the non-triviality lies in the device-independent simultaneous certification of generated randomness from many copies of entangled states. This is because, most of the two-outcome Bell inequalities (viz., Clauser-Horne-Shimony-Holt, Elegant, or Chain Bell inequality) are optimized for a single copy of two-qubit entangled state. Thus, such Bell inequalities can certify neither many copies of entangled states nor a higher amount of randomness. In this work, we suitably invoke a family of n-settings Bell inequalities which is optimized for ⌊n/2⌋ copies of maximally entangled two-qubit states, thereby, possess the ability to certify more randomness from many copies of two-qubit entangled state. © 2022 Elsevier B.V
Relationship of Oxygen Saturation with Neonatal and Maternal factors in Vaginal and Cesarean Deliveries
Introduction: Hypoxemia is the major cause of neonatal morbidity and mortality. The study aims to determine the influence of birth weight, Apgar score, gestation age, body mass index and hemoglobin of mother on levels of SpO2 in healthy newborns born vaginally and through cesarean section.
Methods: A hospital Based, observational study conducted in Department of Pediatrics, Universal College of Medical Sciences-Teaching Hospital, Bhairahawa, Lumbini, Nepal; on 49 vaginal and 49 cesarean deliveries with Apgar Score ≥ 6. SpO2 was estimated by pulse oximeter post-ductally between 1 to 30 minutes of birth. The observed SpO2 values were correlated with neonatal and maternal factors.
Results: Vaginal and Cesarean deliveries SpO2 were comparable for birth weight, gestational age, Apgar score of neonates, body mass index and hemoglobin of the mother. Birth weight in vaginally delivered babies and Apgar score in cesarean births showed significant change in SpO2 (P<0.05). At all points of time the SpO2 values were higher in neonates, born by cesarean than those born out of spontaneous vaginal deliveries (P<0.001).
Conclusions: SpO2 levels in neonates born through cesarean section were higher in comparison to thoseborn by vaginal route. Birth weight and Apgar score had correlation with SpO2 in vaginal and cesarean births, respectively.

Clinico-radiological Observations in Meconium Aspiration Syndrome
Introduction: To understand and report the prevalence of meconium aspiration syndrome and the clinico-radiological features in a tertiary care hospital of western Nepal.
Methods: An observational study carried out for a year in 2014-15 in all babies with MAS. Clinical and radiological profiles of MAS in relation to gender, gestational age, mode of delivery, birth weight, Apgar score, thickness of meconium, age at admission and the immediate outcome were studied.
Results: Out of 584 admitted newborns (male=389; female=186) during the study period, 78 (13.4%) had meconium aspiration syndrome with male: female ratio of 1.2:1. Majority of babies admitted to NICU had thick meconium [n=52 (66.7%)]. There was no statistical significant difference in various parameters such as Apgar score at 1 and 5 minutes, respiratory distress, birth asphyxia, duration of oxygen use, MAS severity and chest x-ray in those with thick MAS compared to thin. Among all newborns with MAS, 59% (n=46) had abnormal radiological findings with over two-folds in those with thick MAS (71.7%)] compared to thin (28%). Hyperinflation (47.8%), diffuse patchy infiltration (37%), consolidation (21.7%) collapse (8.7%), right lung fissure (6.5%) and pneumothorax (8.7%) were the abnormal radiological findings seen in MAS babies. The odds of having APGAR score at 1 minute at least 7 or more was twice unlikely in those having thick meconium compared to thin (P=0.02)
Conclusions: Thick meconium is relatively common with more significant abnormal radiological findings and low Apgar score
