Growth Assessment

Background: Growth assessment including birth weight, length, and head circumference is important to identify infants at risk. However, using international growth curves may be inappropriate for growth assessment of Thai neonates. Objective: To generate a growth chart of infants at the Phramongkutklao Hospital (PMK), and to compare PMK’s growth chart assessment with other international growth charts. Materials and Methods: The authors generated a PMK growth chart from PMK’s newborn database between 2007 and 2016. Birth weight of infants born in 2017 was assessed by using the PMK growth chart in comparison with the Fenton, Lubchenco and Intergrowth Twenty-first growth charts. Results: To generate a PMK growth chart, 22,926 infants were enrolled to the present study. Comparing with other international growth charts, the Fenton exhibited a higher ninetieth percentile of birth weight than others, especially at gestational age of 36 to 41 weeks. In contrast, the Lubchenco exhibited the lowest tenth percentile of birth weight. In 2017, 2,314 infants were born and evaluated by using the PMK, the Fenton, the Lubchenco, and the Intergrowth-21st growth charts. Large for gestational age (LGA) was identified in 185 (8.64%), 55 (2.57%), 166 (7.75%) and 166 (7.75%) infants, respectively. In contrast, small for gestational age (SGA) was identified in 220 (10.27%), 228 (10.64%), 34 (1.59%) and 148 (6.91%) infants, respectively. The admission rate of infants diagnosed as LGA by PMK, but appropriate for gestational age (AGA) by Fenton was higher than other AGA infants. Conclusion: The PMK reference of neonatal growth is up-to-date and applicable. Growth assessment using the Fenton growth chart at late preterm and term gestations may be inaccurate to identify LGA infants. In contrast, the Lubchenco growth chart has limitation to identify SGA infants. Data accumulation from multi-centers at different regions of Thailand are warranted to generate a Thai neonatal growth reference.

Introduction: Birth weight is a major contributor to neonatal morbidity and mortality and is associated with chronic diseases in adulthood. This study aimed to evaluate the use of Intergrowth 21st instead of the Fenton & Kim 2013 growth charts in the diagnosis of small and large for gestational age in a group of Portuguese newborns.Material and Methods: We conducted an analytical and retrospective study to evaluate birth weight of term and preterm newborns using both growth charts. Groups studied: ‘Term-weeks’ and ‘Term-days’ (term newborns with gestational age in weeks and days, respectively), ‘Preterm-weeks’ and ‘Preterm-days’ (preterm newborns with gestational age in weeks and days, respectively).Results: A total of 14 056 newborns were included, 6% preterm. Using the Intergrowth 21st growth charts, the groups ‘Term-weeks’ (n = 12 081), ‘Term-days’ (n = 1118), ‘Preterm-weeks’ (n = 617) and ‘Preterm-days’ (n = 240), classified as small for gestational age according to the Fenton & Kim 2013 growth charts were adequate for gestational age in 52.8%, 57.8%, 37.7% and 9.3% respectively; and 9.2%, 9.2%, 5.9% and 0.6% of adequate for gestational age newborns were large for gestational age, respectively. In the ‘Pretermdays’ group, 7.9% of adequate for gestational age newborns were small for gestational age and 22.2% of large for gestational age newborns were adequate for gestational age, all with gestational age below 231 days.Discussion: The use of the Intergrowth 21st growth charts in this sample resulted in a lower number of newborns being classified as small for gestational age, except in very preterm newborns.Conclusion: Considering the results obtained, we suggest that Portuguese maternity hospitals use the Intergrowth 21st instead of the Fenton & Kim 2013 growth charts. However, more studies are needed to confirm these results.

AbstractBackground:Due to the extremely low incidence of TORCH (toxoplasmosis, rubella, CMV, herpes simplex virus) infections, diagnostic testing of all small for gestational age (SGA) infants aimed at TORCH etiologies may incur unnecessary tests and cost.Objective:To determine the frequency of urine CMV PCR and total IgM testing among infants with birth weight <10% and the rate of test positivity. To evaluate the frequency of alternative etiologies of SGA in tested infants.Methods:Retrospective chart review of SGA infants admitted to the neonatal intensive care unit (NICU) at NYU Langone Medical Center between 2007 and 2012. Subjects were classified as being SGA with or without intrauterine growth restriction (IUGR). The IUGR subjects were then further categorized as having either symmetric or asymmetric IUGR utilizing the Fenton growth chart at birth. Initial testing for TORCH infections, which included serum total IgM, CMV PCR and head ultrasound, were reviewed and analyzed.Results:Three hundred and eighty-six (13%) infants from a total of 2953 NICU admissions had a birth weight ≤10thpercentile. Of these, 44% were IUGR; 34% being symmetric IUGR and 10% asymmetric. A total of 32% of SGA infants had urine CMV PCR and total IgM tested with no positive results. As expected, significantly higher percentage of symmetric IUGR infants were tested compared to asymmetric IUGR and non-IUGR SGA infants, (64% vs. 47% vs. 19%) P≤0.01. However, 63% of infants with a known cause for IUGR had same testing done aimed at TORCH infections. We calculated additional charges of $64,065 that were incurred by such testing.Conclusions:The majority of infants in our study who received testing for urine CMV PCR and total IgM aimed at TORCH infections had one or more other known non-infectious etiologies for IUGR. Because the overall yield of such testing is extremely low, we suggest tests for possible TORCH infections may be limited to symmetric IUGR infants without other known etiologies. Improved guidelines testing for TORCH infections can result in reducing hospital charges and unnecessary studies.

Colloid osmotic pressure (COP) of blood was measured directly at birth with the Wescor membrane colloid osmometer (model 4100) in 91 appropriately grown, 11 large, and nine small for gestational age "well" newborn infants. COP correlated directly with birth weight (r = .726, P &lt; .00001) and gestational age (r = .753, P &lt; .00001). COP values for small for gestational age (SGA) and large for gestational age (LGA) infants were found to fall within the 95% prediction interval with regard to birth weight and gestational age for appropriate for gestational age (AGA) infants. Simultaneous measurements of COP, total serum solids, and central arterial mean blood pressure were made. The results showed that COP correlated directly with total serum solids (r = .89, P &lt; .0001) and mean arterial blood pressure (r = .660, P &lt; .001). Among the factors evaluated, total serum solids was the best predictor of COP.

Abstract Objective To determine the association between total gestational weight gain and perinatal outcomes. Study Design Data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be (NuMoM2b) study were used. Total gestational weight gain was categorized as inadequate, adequate, or excessive based on the 2009 Institute of Medicine guidelines. Outcomes examined included hypertensive disorders of pregnancy, mode of delivery, shoulder dystocia, large for gestational age or small for-gestational age birth weight, and neonatal intensive care unit admission. Results Among 8,628 women, 1,666 (19.3%) had inadequate, 2,945 (34.1%) had adequate, and 4,017 (46.6%) had excessive gestational weight gain. Excessive gestational weight gain was associated with higher odds of hypertensive disorders (adjusted odds ratio [aOR] = 2.05, 95% confidence interval [CI]: 1.78–2.36) Cesarean delivery (aOR = 1.24, 95% CI: 1.09–1.41), and large for gestational age birth weight (aOR = 1.49, 95% CI: 1.23–1.80), but lower odds of small for gestational age birth weight (aOR = 0.59, 95% CI: 0.50–0.71). Conversely, inadequate gestational weight gain was associated with lower odds of hypertensive disorders (aOR = 0.75, 95% CI: 0.62–0.92), Cesarean delivery (aOR = 0.77, 95% CI: 0.65–0.92), and a large for gestational age birth weight (aOR = 0.72, 95% CI: 0.55–0.94), but higher odds of having a small for gestational age birth weight (aOR = 1.64, 95% CI: 1.37–1.96). Conclusion Both excessive and inadequate gestational weight gain are associated with adverse maternal and neonatal outcomes.

AbstrakPreeklampsia dan eklampsia tidak hanya berdampak bagi ibu, tetapi juga terhadap janin yang dikandungnya, seperti hambatan pertumbuhan janin intrauterin yang dapat dilihat dari berat lahir bayi tersebut. Ibu dengan preeklampsia berat/ eklampsia early onset cenderung melahirkan bayi dengan berat lahir Kecil untuk Masa Kehamilan (KMK), sementara yang  late onset cenderung melahirkan bayi dengan berat lahir Sesuai untuk Masa Kehamilan (SMK) atau bahkan Besar untuk Masa Kehamilan (BMK). Tujuannya penelitian ini adalah menentukan perbedaan berat lahir bayi pasien preeklampsia berat/ eklampsia early dan late onset. Penelitian ini dilaksanakan dari Oktober 2012 sampai Juli 2013 di bagian Rekam Medik RSUP Dr. M. Djamil Padang. Jenis penelitian yang digunakan adalah observasional analitik dengan desain cross sectional. Hasil penelitian menunjukkan bahwa angka kejadian preeklampsia berat/ eklampsia early onset adalah 26,1% dan yang late onset sebanyak 73,9%. Bayi KMK lebih banyak dilahirkan oleh ibu preeklampsia berat/ eklampsia early onset (16,67%) dibandingkan dengan yang  late onset (7,35%). Setelah dilakukan analisis melalui uji chi-square, disimpulkan bahwa tidak ada perbedaan berat lahir bayi antara pasien preeklampsia berat/eklampsia early dan late onset secara signifikan (p>0,05).Kata kunci: preeklampsia berat/eklampsia early onset, preeklampsia berat/eklampsia late onset, berat lahir bayi AbstractPreeclampsia and eclampsia are not only effect to mother, but also influent to the fetus, such as intrauterine fetal growth retardation  which can be seen as baby's birth weight. Mothers with early onset severe preeclampsia / eclampsia tend to give birth small for gestational age  babies, while the late onset tend to give birth normal birth weight or large for gestational age babies. The objective of this study was to determine the differentiation between baby's birth weight of early and late onset severe preeclampsia/ eclampsia. The research was conducted from October 2012 to July 2013 at the medical records department of general hospital center Dr. M. Djamil Padang. The type of this research was observational analytic with cross sectional design. The results showed that the incidence of early onset severe preeclampsia/ eclampsia was 26.1% and late onset was 73.9%. Small for gestational age babies born from mothers with early onset severe preeclampsia/ eclampsia (16.67%) is more than the late onset (7.35%). After analyzed by chi square test, it was concluded that there was no differentiation between baby's birth weight of early and late onset severe preeclampsia/ eclampsia significantly (p> 0,05).Keywords: early onset severe preeclampsia/eclampsia, late onset severe preeclampsia/eclampsia, baby’s birth weight

AbstractLow birth weight is associated with an increased risk of adverse outcomes in many diseases in adult life. We investigated the expression of IGF-II and the status of differentially methylated regions (DMR) in small for gestational age (SGA) infants after birth.Plasma IGF-II, IGF-II receptor (IGF2R), IGF-I, and IGF-binding protein 3 (IGFBP3) levels were measured after birth in 150 newborn infants. These included 30 term appropriate for gestational age (AGA), 30 term SGA, 30 term large for gestational age (LGA), 30 preterm AGA, and 30 preterm SGA infants.Plasma IGF-II levels after birth were lower in both term SGA (435.1±33.82 vs. 620.4±44.79, p=0.002) and LGA infants (483.7±33.8 vs. 620.42±44.79, p=0.018) than in term AGA infants. The expression ofIGF-II was associated with birth weight and expressed at high levels, which suggests that IGF-II may continue to play an important role after birth.

BACKGROUND: Only one study has investigated the combined effect of maternal asthma and obesity on perinatal outcomes; however, it did not consider small-for-gestational age and large-for-gestational age infants.OBJECTIVES: To examine the impact of obesity on perinatal outcomes among asthmatic women.METHODS: A cohort of 1386 pregnancies from asthmatic women was reconstructed using three of Quebec’s administrative databases and a questionnaire. Women were categorized using their prepregnancy body mass index. Underweight, overweight and obese women were compared with normal weight women. The primary outcome was the birth of a small-for-gestational-age infant, defined as a birth weight below the 10th percentile for gestational age and sex. Secondary outcomes were large-for-gestational-age infants (birth weight >90th percentile for gestational age) and preterm birth (<37 weeks’ gestation). Logistic regression models were used to obtain the ORs of having small-for-gestational-age infants, large-for-gestational-age infants and preterm birth as a function of body mass index.RESULTS: The proportions of underweight, normal weight, overweight and obese women were 10.8%, 53.3%, 19.7% and 16.2%, respectively. Obese asthmatic women were not found to be significantly more at risk for giving birth to small-for-gestational-age infants (OR 0.6 [95% CI 0.4 to 1.1]), large-for-gestational-age infants (OR 1.2 [95% CI 0.7 to 2.2]) or having a preterm delivery (OR 0.7 [95% CI 0.4 to 1.3]) than normal-weight asthmatic women.CONCLUSIONS: No significant negative interaction between maternal asthma and obesity on adverse perinatal outcomes was observed.

Birth weight is not enough to evaluate growth of the newborn. Around the globe, growth charts at birth as percentiles for various gestational ages are available both in developed and developing countries. This study aimed to develop such growth chart in Bangladesh, to exactly evaluate an individual newborn’s growth pattern by comparing growth of its different parts with that of a standard one. A cross sectional observational study conducted at fifteen non-government maternity centers located in different parts of Dhaka, Narayanganj and Narsingdi. Birth weight, birth length, head and chest circumferences of five thousand one hundred and five singleton newborns’ with gestational ages ranging from 35 to 42 weeks were recorded during June 2014 to July 2015. Trained Physicians and paramedics of respective centers recorded data. Gestational age specific percentile charts were constructed for birth weight, birth length, head circumference and chest circumference. Mean birth weight, birth length, head and chest circumferences were found to be respectively 2966g, 47.1, 33.2 and 32.3 cm which were more or less comparable to some other studies in the country and also higher than some of the studies. Most strikingly, prevalence of low birth weight was found to be 11 percent which is significantly lower than any other study conducted in the country. The 10th, 50th and 90th percentile values of birth weight at 40th weeks of gestation were respectively found to be 2600g, 3000g and 3600g. The linear and circumference growth at 40th weeks of gestation match with the percentile values of birth weight. Constructed growth charts are more or less comparable to some South Asian countries but also significantly differ from some other studies. Country specific standard growth chart is required for clinical assessment and identifying high risk newborns for providing special care. The growth charts constructed in this study, will guide policy makers and programme personnel to take necessary interventions for ensuring potential growth of every future newborn. Furthermore, this study has made the opportunity to compare the charts with other South Asian countries and developed world.

The human milk (HM) microbiota is a significant source of microbes that colonize the infant gut early in life. The aim of this study was to compare transient and mature HM virome compositions, and also possible changes related to the mode of delivery, gestational age, and weight for gestational age. Overall, in the 81 samples analyzed in this study, reads matching bacteriophages accounted for 79.5% (mainly Podoviridae, Myoviridae, and Siphoviridae) of the reads, far more abundant than those classified as eukaryotic viruses (20.5%, mainly Herpesviridae). In the whole study group of transient human milk, the most abundant families were Podoviridae and Myoviridae. In mature human milk, Podoviridae decreased, and Siphoviridae became the most abundant family. Bacteriophages were predominant in transient HM samples (98.4% in the normal spontaneous vaginal delivery group, 92.1% in the premature group, 89.9% in the C-section group, and 68.3% in the large for gestational age group), except in the small for gestational age group (only ~45% bacteriophages in transient HM samples). Bacteriophages were also predominant in mature HM; however, they were lower in mature HM than in transient HM (71.7% in the normal spontaneous vaginal delivery group, 60.8% in the C-section group, 56% in the premature group, and 80.6% in the large for gestational age group). Bacteriophages still represented 45% of mature HM in the small for gestational age group. In the transient HM of the normal spontaneous vaginal delivery group, the most abundant family was Podoviridae; however, in mature HM, Podoviridae became less prominent than Siphoviridae. Myoviridae was predominant in both transient and mature HM in the premature group (all C-section), and Podoviridae was predominant in transient HM, while Siphoviridae and Herpesviridae were predominant in mature HM. In the small for gestational age group, the most abundant taxa in transient HM were the family Herpesviridae and a species of the genus Roseolovirus. Bacteriophages constituted the major component of the HM virome, and we showed changes regarding the lactation period, preterm birth, delivery mode, and birth weight. Early in life, the HM virome may influence the composition of an infant’s gut microbiome, which could have short- and long-term health implications. Further longitudinal mother–newborn pair studies are required to understand the effects of these variations on the composition of the HM and the infant gut virome.

Abstract Purpose: To determine whether being small for gestational age (SGA), appropriate for gestational age (AGA) and large for gestational age (LGA) affected the sensitivity and specificity of Postnatal Growth and Retinopathy of Prematurity (G-ROP) model. Methods: We applied the G-ROP criteria, except hydrocephalus, for prematures retrospectively. The infants were divided into three subgroups according to birth weight percentiles (SGA, AGA, LGA), and the performance of the G-ROP criteria was tested for each group by calculating sensitivity and specificity for any stage retinopathy of prematurity (ROP) and severe ROP. Severe ROP was defined as ROP needing treatment. Results: Three hundred and ninety neonates screened for ROP were included. The gestational age and birth weight of the neonates were 29.3±2.9 weeks and 1302.9±416 g, respectively. There were 41 (10.5%) SGA, 312 (80%) AGA and 37 (9.5%) LGA neonates. The sensitivity of the model for any ROP was 67.8%, 66.7%, 73.2%, 55.6% for all of the patients in the study, SGA, AGA, and LGA neonates, respectively. The sensitivity of the model for severe ROP in all group and for each subgroup was 100%. The specificity of the model for any ROP was 65.9%, 70.6%, 87.7%, 90% for all of the patients, SGA, AGA, and LGA neonates, respectively. The specificity for severe ROP was 46.4%, 50%, 44%, 63.6% for all of the patients, SGA, AGA, and LGA neonates, respectively.Conclusion: The sensitivity and specificity of the G-ROP model in SGA infants were similar with the whole group, but was different between SGA, AGA and LGA neonates. Although the model did not miss any severe ROP, the specificity of the model for severe ROP was found low.
