Usefulness of Mean Gastric Emptying Time in Late Preterm and Term AGA and SGA Newborns to Determine Feeding Frequency—An Observational Study

Objectives The primary objective is to calculate and compare mean gastric emptying time in appropriate for gestational age (AGA) and small for gestational age (SGA) newborns. The secondary objective is to compare mean gastric emptying time in SGA babies with or without antenatal Doppler changes and to measure gastric spheroidal volume at various intervals in AGA and SGA newborns with or without antenatal Doppler changes. Methods This prospective observational study was carried over 3 months from November 2022 to January 2023. A total of 30 newborns were enrolled and their gastric spheroidal volume was calculated by ultrasound pre-feed and post-feed every 30 minutes till it reached within 10% of pre-feed volume which was taken as gastric emptying time. Mean gastric emptying time was compared among AGA and SGA newborns and amongst SGA with or without antenatal Doppler changes. Results Mean gastric emptying time of AGA was 124 ± ± 25.01 minutes and for SGA was 132 ± 29.57 minutes which was statistically nonsignificant. Mean gastric emptying time when compared between SGA neonates with or without antenatal Doppler changes was similar ( P value .43). The gastric spheroidal volume was significantly smaller in SGA newborns compared to their AGA counterparts in pre-feed state ( P value .01) and it persisted till 60 minutes post feed ( P value .028); however, the mean gastric emptying time is similar in both the groups. Conclusion Mean gastric emptying time of AGA and SGA newborns is similar and hence a feeding interval of 1.5 to 2.5 hours is appropriate for these late preterm and term newborns. Antenatal Doppler changes in SGA babies did not alter their gastric emptying time hence similar feeding frequency can be used in both.

Classification and Special Nutritional Needs of SGA Infants and Neonates of Multiple Pregnancies.

Data regarding the nutritional management of preterm small for gestational age (SGA) infants are scarce. In the recent report of ESPGHAN, the recommended energy for very preterm infants during hospitalization has been increased, yet this may not fit the needs of all preterm infants. It is important to distinguish fetal growth-restricted (FGR) infants from constitutional SGA infants, as well as preterm SGA from preterm AGA infants, since they may have different nutritional needs. Preterm FGR infants, and specifically infants < 29 weeks' gestation, accumulate nutrient deficits due to intrauterine malnutrition, prematurity, morbidities, delayed initiation of feeding, and feeding intolerance. Therefore, these infants may need more aggressive nutrition for optimal catch-up growth and neurologic development. However, a balance should be kept between optimal and excessive catch-up growth, since the combination of intrauterine malnutrition and excessive postnatal growth has been linked with later adverse metabolic consequences. Furthermore, multiple gestation is often complicated by FGR and prematurity. There is controversy in the definition of FGR in multiple gestations, and it should be noted that FGR in multiple gestation usually differs etiologically from FGR in singletons. The aim of this review is to summarize existing knowledge regarding the nutritional needs of preterm FGR and FGR infants of multiple gestation.

Prenatal Diagnosis of Isolated Single Umbilical Artery: Incidence, Risk Factors and Impact on Pregnancy Outcomes.

Objectives: To assess the incidence of prenatally diagnosed isolated single umbilical artery (iSUA) and its impact on major pregnancy outcomes, as well as to investigate potential risk factors. Materials and methods: A prospective study of singleton pregnancies, undergoing routine anomaly scans at 20+0-24+0 weeks of gestation, was carried out from 2018 to 2022. The effect of sonographically detected iSUA on small-for-gestational-age neonates (SGA) and preterm delivery (PTD) was evaluated using parameterized Student's t-test, nonparametric Mann-Whitney U test and the chi-square test. Multivariable logistic regression models were implemented to assess the independent association between iSUA and the main outcomes, as well as with potential risk factors, while adjusting for specific confounders. Results: The study population included 6528 singleton pregnancies and the incidence of prenatally diagnosed iSUA was 1.3%. Prenatally diagnosed iSUA had a statistically significant association with both SGA neonates (aOR: 1.909; 95% CI: 1.152-3.163) and PTD (aOR: 1.903; 95% CI: 1.035-3.498), while no association was identified between this sonographic finding and preeclampsia. With regard to risk factors, conception via assisted reproductive technology (ART) was associated with increased risk of iSUA (aOR: 2.234; 95% CI: 1.104-4.523), while no other independent predictor for the development of this anatomical variation was identified. Conclusions: Prenatally diagnosed iSUA seems to be associated with a higher incidence of SGA and PTD and is more common in pregnancies following ART, which constitutes a novel finding.

Fetal Gastroschisis: Does Fetal Growth Restriction Correlate With Small for Gestational Age at Birth? [ID: 1375594

INTRODUCTION: Conflicting data exist regarding the optimal formula for calculating estimated fetal weight (EFW) in fetuses with gastroschisis. The widely used Hadlock formula includes abdominal circumference (AC) and may underestimate EFW, as fetuses with gastroschisis tend to have a smaller AC. We evaluated 1) correlation between EFW and birth weight (BW) and 2) agreement between fetal growth restriction (FGR) and small for gestational age (SGA) in fetuses/neonates with gastroschisis. METHODS: This was an IRB-approved single-center retrospective cohort study at a tertiary care center. Data were obtained from 2012 to 2021 and included singleton pregnancies with at least one growth ultrasound (US) performed by our center and neonate born at our center with confirmed gastroschisis. Pearson correlation was used to examine association between EFW and BW. Kappa statistic was used to examine agreement between FGR and SGA. RESULTS: Thirty-five maternal–neonatal pairs were included. There was a strong correlation between EFW on last growth US and BW (r=0.70, 95% CI [0.48, 0.84], P&lt;.001). There was disagreement between FGR on last US and SGA at birth (Kappa coefficient=0.11, 95% CI [0.00, 0.22], P&lt;.001) with 26 (74.3%) FGR fetuses, 5 (14.3%) of which were SGA neonates. CONCLUSION: Although EFW and BW were strongly correlated, less than one-fifth of fetuses diagnosed with FGR became neonates classified as SGA, suggesting that an EFW formula including AC overestimates FGR in fetuses with gastroschisis. Accurate estimation of EFW is necessary for antenatal testing, delivery planning, and avoiding unnecessary interventions. An alternative EFW formula could be considered for fetuses with gastroschisis.

Pregnancy Outcome of Confined Placental Mosaicism: Meta-analysis of Cohort Studies

ABSTRACT Confined placental mosaicism (CPM) is a condition in which there is chromosomal abnormality in the placenta that is not present in the fetus. Confined placental mosaicism has historically been most often identified following a first-trimester chorionic villus sampling (CVS), in which there are 2 different cell lines in the placenta but a normal karyotype in the fetus based on amniocentesis or neonatal blood. As the outcome for CPM pregnancies is still debated, including the potential for adverse pregnancy and postnatal outcomes, this study aimed to evaluate the rates of adverse neonatal and obstetrical outcomes in CPM-diagnosed pregnancies, as compared with unaffected matched controls. This meta-analysis was performed in accordance with an a priori designed protocol and was registered with the PROSPERO (International Prospective Register of Systematic Reviews) database. A search of EMBASE and MEDLINE databases from 1980 to February 2022 was performed. Included articles were published in the English language and were observational studies including singleton CPM-diagnosed pregnancies (whose controls were unaffected and with normal karyotype). Excluded were all reviews, case reports, and congress abstracts. In addition, high-risk or positive cell-free DNA screening (cfDNA) cases followed by diploid amniotic cells were excluded (because of the different methodology, which may have an effect on the analysis). Because of the paucity of data regarding mosaicism in submicroscopic copy number variants, these abnormalities were also excluded from the analysis. Primary outcomes included the occurrence of the following: termination of pregnancy, major fetal defects (as defined by the Centers for Disease Control and Prevention), small for gestational age (SGA) neonate with birth weight (BW) &lt;10th centile and neonatal SGA with BW less than the third centile, preterm birth (PTB), hypertensive disorders, admission to a neonatal intensive care unit, intrauterine fetal demise at &lt;24 weeks' gestation, and &gt;24 weeks' gestation stillbirth. All other abnormal pregnancy outcomes were searched for, including PTB, obstetrical cholestasis, amniotic infection, gestational diabetes, cesarean delivery, amniotic infection, preterm prelabor rupture of membranes, and neonatal mortality or morbidity. Of 310 retrieved articles, 80 studies were assessed for eligibility, and 8 retrospective matched cohort studies were included. The results of the meta-analysis showed that women with CPM had a higher risk of adverse pregnancy outcomes than those without CPM. The most common adverse outcomes were fetal growth restriction (FGR), PTB, and stillbirth. The risk of FGR was significantly higher in women with CPM, with an odds ratio (OR) of 3.60 (95% confidence interval [CI], 2.40–5.39). Similarly, the risk of PTB was higher in women with CPM, with an OR of 2.64 (95% CI, 1.90–3.67), and the risk of stillbirth was also increased, with an OR of 2.58 (95% CI, 1.51–4.42). Scarcity of reporting for other obstetrical neonatal and obstetrical outcomes hindered further conclusions. In subgroup analysis, the risk of delivering an SGA infant was 3-fold higher for CPM when trisomy 16 was excluded and 11-fold higher for trisomy 16 specifically compared with unaffected controls. The authors acknowledge that the meta-analysis has several limitations, including the heterogeneity of the included studies, the lack of information on the specific type and extent of CPM in each case, and the potential for publication bias. Nevertheless, the study provides valuable insights into the pregnancy outcomes of women with CPM and highlights the need for further research to improve our understanding of this condition. Overall, this meta-analysis suggests that women with CPM are at increased risk of adverse pregnancy outcomes, particularly FGR, PTB, and stillbirth. The findings highlight the importance of early detection of CPM and close monitoring of pregnancies in women with this condition. The study also emphasizes the need for further research to better understand the underlying mechanisms of CPM and to identify effective interventions to improve pregnancy outcomes in affected women.

Race and Ethnicity and Disparities in Neonatal Outcomes in Twin Pregnancies [ID: 1375610

INTRODUCTION: Twin pregnancies are associated with adverse neonatal outcomes. We aimed to investigate disparities in neonatal outcomes by maternal race and ethnicity. METHODS: This was an IRB-approved, retrospective cohort of twin deliveries at a single institution between 2001 and 2018. Pregnancies delivered less than 23 weeks’ gestational age (GA), fetal demise, or major anomaly were excluded. The primary exposure, race and ethnicity, was self-reported as follows: non-Hispanic White, Hispanic, non-Hispanic Black, Asian/Pacific Islander, and other/mixed race. The primary outcome was neonatal intensive care unit (NICU) admission of at least one twin. Secondary outcomes included 5-minute Apgar less than 7 for either twin, GA at delivery, small for GA (SGA) neonate (&lt;10th percentile for GA), and NICU length of stay. Chi-square, ANOVA, and Student’s t test were performed for univariate analyses. Logistic regression modeling was performed to control for baseline differences. RESULTS: Eight hundred four twin pregnancies were identified; 48% of patients identified as non-Hispanic White, 30% as Hispanic, 10% as Asian/Pacific Islander, 5.6% as non-Hispanic Black, and 6.6% as other/mixed race. Age, parity, chorionicity, and body mass index differed between groups. The overall rate of NICU admission was 77.5% and did not differ by race and ethnicity (P=.05). Pregnancies with at least one SGA neonate varied significantly by race and ethnicity (P=.02). Gestational age at delivery, Apgar of less than 7, and ICU length of stay did not differ. CONCLUSION: The risk of having an SGA neonate varies by race and ethnicity in twin gestations, with highest rates among non-Hispanic Black women. Additional racial and ethnic disparities in neonatal morbidity were not found. Disparities in rate of preterm birth were not seen in this cohort.

Allostatic Load and Adverse Pregnancy Outcomes

ABSTRACT Approximately one-fourth of pregnancies experience adverse pregnancy outcomes, such as hypertensive disorders of pregnancy (HDPs), preterm birth, stillbirth, and small-for-gestational age (SGA) neonates. Although an uncertain pathophysiology leading to these outcomes of pregnancy is understood, a major contributing factor may be cumulative stress. Chronic wear and tear on the adaptive system of the body, as well as chronic stress exposure, can be assessed via allostatic load. Chronic stress hailing from circumstances such as food or housing insecurity, racism, unemployment, or a combination of these may contribute to the racial and ethnic disparities observed in pregnancy outcomes. This study aimed to assess the relationship between the allostatic load and adverse pregnancy outcomes, while hypothesizing that higher odds of adverse pregnancy outcomes are directly associated with higher allostatic loads. Second, the authors hypothesized that a significant portion of racial and ethnic disparities in adverse pregnancy outcomes will be accounted for with high allostatic loads. The primary outcome was a composite adverse pregnancy outcome: HDPs, SGA, preterm birth, and stillbirth. Between October 2010 and September 2013, the nuMoM2b study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be) enrolled 10,038 nulliparous individuals with singleton pregnancies. Eligible individuals were nulliparous, had a viable single gestation with an estimated gestational age of 60/7 and 136/7 weeks, and intended delivery at a participating clinical site. Exclusionary criteria were as follows: unable to provide informed consent, age younger than 13 years, planned termination of pregnancy, 3 or more prior pregnancy losses, fetal malformations or aneuploidy upon enrollment, or having a donor ovum pregnancy. Included within the study were 3 study visits during pregnancy and a final visit at delivery. Baseline clinical assessments, standardized questionnaires by trained chart abstracts, and medical record abstraction were used to ascertain maternal characteristics. Assessment of urine and serum collected between 6 and 14 weeks granted insight into allostatic load biomarkers. A total of 4266 pregnant individuals were included in the primary analysis, with high allostatic load being identified in 35% of the population (≥4 biomarkers in the worst quartile). Some 1171 individuals (27.5%) were identified to have adverse pregnancy outcomes: 386 preterm births (8.6%), 586 HDPs (14.0%), 12 stillbirths (0.3%), and 449 SGA neonates (11%). Adverse pregnancy outcomes occurred in the following numbers: 1 adverse outcome for 967 individuals, 2 for 165, 3 for 38, and 1 for all 4. High allostatic load held significant association with composite adverse pregnancy outcome, whereas HDPs differed by self-reported race. After adjustment for maternal age, gravidity, smoking, bleeding in the first trimester, and health insurance, high allostatic load was associated with the composite adverse pregnancy outcome (adjusted odds ratio [aOR], 1.5; 95% confidence interval [CI], 1.3–1.7) and hypertensive disorders (aOR, 2.5; 95% CI, 2.0–2.9), but not preterm birth or SGA. High allostatic load only partially mediated the association between self-reported race and adverse pregnancy outcomes. The association between allostatic load and hypertensive disorders differed by self-reported race, but it did not differ for the composite adverse pregnancy outcome, preterm birth, or SGA. Limitations of the study included the small number of stillbirths. Furthermore, the study used the 10-factor allostatic load index and did not assess additional cardiovascular and metabolic indicators in the broader allostatic load index. In addition, the cohort only included nulliparous individuals with tertiary care center access, which is not necessarily generalizable to other populations. Strengths of the study included its use of a large, well-characterized prospective cohort, as well as equal weighing of allostatic load biomarkers and a study population that was racially, ethnically, and geographically diverse. In conclusion, the study indicates that early-pregnancy high allostatic loads are associated with subsequent adverse pregnancy outcomes (HDPs in particular). Allostatic load was also a partial mediator between adverse pregnancy outcomes and race. Further evaluation of components of chronic stress and allostatic load as potentially modifiable risk factors is supported by these findings as a means of improving pregnancy outcomes via these potentially modifiable risk factors.

Maternal and Placental Risk Factors for Small Gestational Age and Fetal Malnutrition.

This case-control study was conducted to identify maternal and placental risk factors of small-for-gestational-age (SGA) and fetal malnutrition. Cases comprised 104 consecutively delivered SGA neonates (determined as per INTERGROWTH- 21st standard). An equal number of next-born gestation and gender-matched appropriatefor- gestational age (AGA) neonates served as controls. Maternal risk factors were enquired, and placentae were evaluated by clinical and histopathological examination. Nutrition of the neonates was assessed by the clinical assessment of nutrition (CAN) score. Univariate and multivariate logistic regression analysis was done to identify the maternal and placental risk factors. The prevalence of SGA in the present study was 23.9%. Maternal fever [adjusted Odds Ratio (aOR), 95% confidence interval (CI), 16.3 (3.5-124.1); p = 0.001], presence of placental syncytial knots [aOR (95% CI), 2.9 (1.1-9.1); p = 0.04] and placental calcifications [aOR (95% CI), 3(1.1- 8.7); p = 0.03], were identified as independent predictors of SGA using multivariate logistic regression analysis. Malnutrition (SCORE <25) affected 64% of SGA and 16.3% of AGA neonates. The only risk factor significantly associated with malnourished SGA was prematurity, whereas malnourished AGA was significantly associated with prematurity and fetal distress. In-hospital morbidities significantly higher in SGA were perinatal asphyxia, respiratory distress, need for respiratory support, polycythemia, hypoglycemia, and feeding intolerance. Mortality before discharge was 4.8% and 3.8% in SGA and AGA population, respectively (p > 0.05). Neonatal outcomes were comparable among well-nourished, malnourished SGA and AGA groups. Maternal fever, placental syncytial knots, and calcifications were independent risk factors of SGA, whereas prematurity and fetal distress were responsible for malnutrition.

MORBIDITY PATTERN OF SMALL FOR GESTATIONAL AGE BABIES ADMITTED IN A NEONATAL CARE UNIT

Background: The neonatal period of the small for gestational age (SGA) neonates is the most vulnerable phase; the neonatal morbid conditions along with the mortality being the major health issues in the developing countries like Nepal. The objective of this study was to assess the morbidity pattern of the SGA neonates admitted in the neonatal intensive care unit. Methods: A hospital base cross-sectional study was carried out in 100 SGA neonates admitted in the neonatal care unit of College of Medical Sciences Teaching Hospital, Bharatpur, Nepal from May 2020 to April 2021 Small for gestational age neonates (SGA) was defined as birth weight &lt;10th percentile for gestational age by Lubchenco’s growth chart. Infant characteristics and neonatal outcomes were assessed during the hospital stay and the data was entered in the SPSS v23.0. Results: Among the total 100 cases of SGA neonates, 66 % were male. The mean birth weight was 1900 ±SD 381gm (range 1000-2500 gm). Term SGA neonates accounted for 60% while preterm SGA neonates were 40%. Common morbidities seen in SGA neonates were sepsis (44%), hyperbilirubinemia (34%), perinatal depression/birth asphyxia (34%) and shock (22%). While comparing the morbidities between term and preterm neonates, a significant correlation was observed between hypothermia (p-value = 0.001), polycythemia (p-value = 0.001), NEC (p-value= 0.004) and perinatal depression/asphyxia (0.013) with the period of gestation. Mortality was observed in 8% due to various perinatal problems. Conclusions: From this study, we can conclude that SGA is associated with various morbidities, sepsis being the most common morbidity amongst perinatal asphyxia, hyperbilirubinemia, hypothermia and hypoglycemia.

Gestational Weight Gain in Pregnancies Following Bariatric Surgery

IntroductionTo compare the gestational weight gain (GWG) between women with previous bariatric surgery and those without and investigate whether GWG correlates with birthweight (BW) or delivery of a small-for-gestational-age (SGA) neonate.Materials and MethodsProspective, longitudinal study, include 100 pregnant women with previous bariatric surgery and 100 without weight loss surgery, but with similar early-pregnancy body mass index (BMI). In a sub-study, 50 of the post-bariatric women were also matched to 50 women without surgery, but early-pregnancy BMI similar to the pre-surgery BMI of the post-bariatric ones. All women had their weight/BMI measured at 11–14 and 35–37 weeks of gestation, and the difference in maternal weight/BMI between the two time points was expressed as GWG/BMI gain. Associations between maternal GWG/BMI gain and birthweight (BW) were examined.ResultsCompared to no bariatric women with similar early-pregnancy BMI, post-bariatric women had similar GWG (p = 0.46), and the number of women with appropriate, insufficient, and excessive weight gain was comparable between groups (p = 0.76). However, post-bariatric women delivered smaller babies (p < 0.001), and GWG was not a significant predictor of BW or of delivering a SGA neonate. Compared to no bariatric women with similar pre-surgery BMI, post-bariatric ones had higher GWG (p < 0.01) but still delivered smaller neonates (p = 0.001).ConclusionsPost-bariatric women seem to have similar or greater GWG compared to women without surgery matched for early-pregnancy or pre-surgery BMI, respectively. Maternal GWG was not associated with BW or higher prevalence of SGA neonates seen in women with previous bariatric surgery.Graphical

The Association between Infant Birth Weight, Head Circumference, and Neurodevelopmental Outcomes.

The aim of this study was to evaluate whether being small for gestational age (SGA) or large for gestational age (LGA) or having a small or large head circumference (HC) at birth is associated with adverse neurodevelopmental outcomes. This is a secondary analysis of a multicenter negative randomized trial of thyroxine therapy for subclinical hypothyroid disorders in pregnancy. The primary outcome was child intelligence quotient (IQ) at 5 years of age. Secondary outcomes included several neurodevelopmental measures. Associations between the outcomes in children with SGA (<10th percentile) or LGA (>90th percentile) birth weights, using ethnicity- and sex-specific population nomogram as well as nomograms from the National Fetal Growth (NFG) study, were compared with the referent of those with appropriate for gestational age (AGA) birth weight. Similar analyses were performed for HC. Using the population nomogram, 90 (8.2%) were SGA and 112 (10.2%) were LGA. SGA neonates were more likely to be born preterm to mothers who were younger, smoked, and were less likely to have less than a high school education, whereas LGA neonates were more likely to be born to mothers who were older and have higher body mass index, compared with AGA neonates. SGA at birth was associated with a decrease in the child IQ at 5 years of age by 3.34 (95% confidence interval [CI], 0.54-6.14) points, and an increase in odds of child with an IQ < 85 (adjusted odds ratio [aOR], 1.9; 95% CI, 1.1-3.2). There was no association between SGA and other secondary outcomes, or between LGA and the primary or secondary outcomes. Using the NFG standards, SGA at birth remained associated with a decrease in the child IQ at 5 years of age by 3.14 (95% CI, 0.22-6.05) points and higher odds of an IQ < 85 (aOR, 2.3; 95% CI, 1.3-4.1), but none of the other secondary outcomes. HC was not associated with the primary outcome, and there were no consistent associations of these standards with the secondary outcomes. In this cohort of pregnant individuals with hypothyroid disorders, SGA birth weight was associated with a decrease in child IQ and greater odds of child IQ < 85 at 5 years of age. Using a fetal growth standard did not appear to improve the detection of newborns at risk of adverse neurodevelopment.

Perinatal Outcomes After Bariatric Surgery Compared With a Matched Control Group.

To evaluate perinatal outcomes associated with pregnancy after bariatric surgery within a large integrated health care system using propensity score matching. We conducted a retrospective cohort study that evaluated perinatal outcomes in pregnant patients after bariatric surgery from January 2012 through December 2018. History of bariatric surgery was identified by using International Classification of Diseases codes and a clinical database. Primary outcomes were preterm birth (PTB), gestational hypertension, preeclampsia, impaired glucose tolerance or gestational diabetes, a large-for-gestational-age (LGA) or small-for-gestational-age (SGA) neonates, and cesarean birth. Propensity scores were estimated by using logistic regression that accounted for age at delivery, prepregnancy body mass index, year of delivery, parity, neighborhood deprivation index, race and ethnicity, insurance status, initiation of prenatal visit in the first trimester, smoking during pregnancy, chronic hypertension, and preexisting diabetes. Five patients in the control group were matched to each patient in the case group on linear propensity score, and modified Poisson regression was used to adjust for covariates. Sensitivity analyses by timing and type of surgery were performed. We identified a case cohort of 1,591 pregnancies in patients after bariatric surgery and a matched cohort of 7,955 pregnancies in patients who had not undergone bariatric surgery. Demographic characteristics were similar in both groups. In multivariate models, pregnancy after bariatric surgery was associated with a decreased risk of preeclampsia (7.5% vs 10.2%, adjusted relative risk [aRR] 0.72, 95% CI 0.60-0.86), gestational diabetes or impaired fasting glucose (23.5% vs 35.0%, aRR 0.73, 95% CI 0.66-0.80), and LGA (10.6% vs 19.9%, aRR 0.56, 95% CI 0.48-0.65) and an increased risk of SGA (10.9% vs 6.6%, aRR 1.51, 95% CI 1.28-1.78). No significant differences were observed in PTB, gestational hypertension and cesarean delivery. Pregnancy after bariatric surgery in a racially and ethnically diverse cohort of patients is associated with decreased risk of preeclampsia, gestational diabetes or impaired fasting glucose, and LGA neonates; it is also associated with an increased risk of SGA neonates compared with pregnant patients in a matched control group.

HYPOGLYCEMIA IN EXCLUSIVELY BREASTFED LOW BIRTH WEIGHT NEONATES

Background and Aim: Hypoglycemia is an important problem encountered in Low Birth Weight (LBW) neonates. Incidence and risk factors associated with hypoglycemia in low birth weight neonates on exclusive breast milk were studied. Material and Methods: A Prospective observational study was done between Jan-June 2022. Low birth weight neonates (≥1.8 kg &lt;2.5 kg) who were fed exclusively with breast milk were screened for hypoglycemia by measuring capillary blood glucose by glucometer strips at 1 , 2 , 6 , 12 , 24 , 48 and 72 hours of age. Results: 180 Low Birth Weight neonates were included in the study, of which 41 developed hypoglycemia with incidence of 22.7%. Majority of them (85.3%) were asymptomatic . 70.7 % of hypoglycemia episodes occurred in rst 24 hours of life. 58.5% neonates with hypoglycemia had only one episode while 31.7% and 9.8% had 2 and 3 or more episodes of hypoglycemia respectively. Incidence was more in Pre term (PT) (27.3%) compared to Full Term(FT) neonates (16.2%). Also Small for Gestational Age (SGA) neonates were more prone to hypoglycemia compared to Appropriate for Gestational Age (AGA) neonates (48.2 % against 18.4%) Incidence in PT SGA, FT SGA and PT AGA neonates was 27.9%,20.3 &amp; 18.4% respectively. Incidence was also more in neonates born to primigravida mothers and those delivered by cesarean section. Conclusion: Low birth weight Neonates especially late preterms and SGAneonates on exclusive breast milk should be monitored for hypoglycemia in rst 72 hours of life. Early initiation of breast feeding should be ensured to prevent hypoglycemia in them.

TO STUDY SMALL FOR GESTATIONAL AGE AS A RISK FACTOR FOR THYROID DYSFUNCTION

Introduction: Babies with a birth weight and/or length below the 10th percentile of a population of the same gestational age are dened small-forgestational-age (SGA). Children born prematurely or small for gestational age are at a higher risk of thyroid dysfunction. Intrauterine growth retardation and the delivery of SGA infants may have a variety of reasons. This illness is characterised by several endocrine-metabolic changes and pathophysiological processes. It has been shown that there are greater rates of diseases including cardiovascular events, metabolic syndrome, hypertension, and obesity. These changes may also have an impact on future health in infancy and adulthood. There aren't many research that compare the thyroid function of SGA and AGA neonates. For newborn plasma concentrations of T4 and TSH, contradictory ndings have been reported. The study was conducted to observe the relationship that the weight and/ Objective: or the gestational age plays on the thyroid function of the babies.

SGA babies had a hi Conclusion: gher incidence of transient hypothyroidism and required accurate follow-up and close monitoring of thyroid function.

Maternal and neonatal outcomes of singleton versus twin pregnancies complicated by gestational diabetes mellitus: A systematic review and meta-analysis.

There is limited evidence exploring the maternal and neonatal complications of gestational diabetes mellitus (GDM) following singleton or twin pregnancies. Further, there have been no reviews completed examining the possible risk factors associated with GDM in singleton compared to twin pregnancies. This study assesses the impact of GDM in singleton and twin pregnancies on maternal and neonatal outcomes. From 1954 to December 2021, a thorough literature search was conducted in the EMBASE, Cochrane, MEDLINE, ScienceDirect, and Google Scholar databases and search engines. The risk of bias was calculated using the Newcastle Ottawa (NO) scale. A random-effects model was applied and interpreted as pooled odds ratio (OR) with 95% confidence intervals (CI). Eight studies satisfied the inclusion criteria, with the quality of most studies being good to satisfactory. The risk of caesarean section (pooled OR = 0.32; 95%CI: 0.22 to 0.46), small-for-gestational age (SGA) neonates (pooled OR = 0.40; 95%CI: 0.19 to 0.84), preterm delivery (pooled OR = 0.07; 95%CI: 0.06 to 0.09), respiratory morbidity (pooled OR = 0.26; 95%CI: 0.19 to 0.37), neonatal hyperbilirubinemia (pooled OR = 0.19; 95%CI: 0.10 to 0.40), and NICU admission (pooled OR = 0.18; 95%CI: 0.14 to 0.25) was significantly lower in singleton pregnancies with GDM than in twin pregnancies with GDM. Maternal outcomes like caesarean section and neonatal outcomes like SGA neonates, preterm delivery, respiratory morbidity, hyperbilirubinemia, and NICU admission were significantly greater in twin pregnancies with GDM. It is important for clinicians and policymakers to focus intervention strategies on twin pregnancies with GDM.

Maternal plasma syndecan-1: a biomarker for fetal growth restriction

Objective The identification of fetal growth disorders is an important clinical priority given that they increase the risk of perinatal morbidity and mortality as well as long-term diseases. A subset of small-for-gestational-age (SGA) infants are growth-restricted, and this condition is often attributed to placental insufficiency. Syndecan-1, a product of the degradation of the endothelial glycocalyx, has been proposed as a biomarker of endothelial damage in different pathologies. During pregnancy, a “specialized” form of the glycocalyx—the “syncytiotrophoblast glycocalyx”—covers the placental villi. The purpose of this study was to determine whether the concentration of maternal plasma syndecan-1 can be proposed as a biomarker for fetal growth restriction. Study design A cross-sectional study was designed to include women with normal pregnancy (n = 130) and pregnant women who delivered an SGA neonate (n = 50). Doppler velocimetry of the uterine and umbilical arteries was performed in women with an SGA fetus at the time of diagnosis. Venipuncture was performed within 48 h of Doppler velocimetry and plasma concentrations of syndecan-1 were determined by a specific and sensitive immunoassay. Results (1) Plasma syndecan-1 concentration followed a nonlinear increase with gestational age in uncomplicated pregnancies (R2 = 0.27, p < .001); (2) women with a pregnancy complicated with an SGA fetus had a significantly lower mean plasma concentration of syndecan-1 than those with an appropriate-for-gestational-age fetus (p = .0001); (3) this difference can be attributed to fetal growth restriction, as the mean plasma syndecan-1 concentration was significantly lower only in the group of women with an SGA fetus who had abnormal umbilical and uterine artery Doppler velocimetry compared to controls (p = .00071; adjusted p = .0028). A trend toward lower syndecan-1 concentrations was also noted for SGA with abnormal uterine but normal umbilical artery Doppler velocimetry (p = .0505; adjusted p = .067); 4) among women with an SGA fetus, those with abnormal umbilical and uterine artery Doppler findings had a lower mean plasma syndecan-1 concentration than women with normal Doppler velocimetry (p = .02; adjusted p = .04); 5) an inverse relationship was found between the maternal plasma syndecan-1 concentration and the umbilical artery pulsatility index (r = −0.5; p = .003); and 6) a plasma syndecan-1 concentration ≤ 850 ng/mL had a positive likelihood ratio of 4.4 and a negative likelihood ratio of 0.24 for the identification of a mother with an SGA fetus who had abnormal umbilical artery Doppler velocimetry (area under the ROC curve 0.83; p < .001). Conclusion Low maternal plasma syndecan-1 may reflect placental diseases and this protein could be a biomarker for fetal growth restriction. However, as a sole biomarker for this condition, its accuracy is low.

Undetected Fetal Growth Restriction During the Coronavirus Disease 2019 (COVID-19) Pandemic.

This was a retrospective cohort study of patients who delivered singleton, small-for-gestational-age (SGA) neonates between April and June 2019, before the coronavirus disease 2019 (COVID-19) pandemic (pre-COVID-19), and between April and July 2020, during the pandemic (COVID-19 epoch). The primary outcome was the rate of undetected antenatal fetal growth restriction (FGR) in the two periods. A total of 268 patients met inclusion criteria. Patients who delivered small-for-gestational-age neonates during the COVID-19 epoch were significantly more likely to have undetected FGR compared with those who delivered pre-COVID-19 (70.1% vs 58.1%, P =.04). Patients who delivered SGA neonates during the COVID-19 epoch had more telehealth visits but fewer in-person prenatal visits, recorded fundal height measurements, and growth ultrasonograms. As telemedicine continues to be incorporated into prenatal care, these data may lend further support toward self-assessment of fundal height or routine third-trimester growth ultrasonograms to identify fetal growth abnormalities.

Iron Profile in Term Small for Gestational Age Infants at 10 Weeks of Age and Correlation With Maternal Iron Profile: A Prospective Cohort Study

Term small for gestational age (SGA) babies are at risk for developing iron deficiency anemia. The association between maternal and infant iron stores is not clear. To assess proportion of term SGA neonates developing iron deficiency anemia by 10 weeks of age, and measure correlation between iron profile and hepcidin of babies at birth and at 10 weeks of age with maternal iron profile. Prospective cohort study conducted from November, 2018 to April, 2020. 120 term SGA babies and their mothers. Hemogram, iron profile and serum hepcidin (every fourth case) estimated in mother, cord blood and baby at 10 weeks. Babies developing anemia at 6 weeks detected by hemogram and ferritin were started on iron supplementation and excluded from the study. Proportion of babies developing iron deficiency anemia at 10 weeks of age. 35 (29.2%) of 120 term SGA babies developed anemia (hemoglobin <9 g/dL) at 6 weeks. Proportion of infants who developed iron deficiency anemia (hemoglobin <9 g/dL and serum ferritin <40 µ/dL) at 6 and 10 weeks of age was 14.2% and 23.3%, respectively. No significant correlation was found bet-ween hemoglobin, iron and hepcidin of the baby in cord blood and at 10 weeks of age with that of mothers. Serum hepcidin in babies at birth (137.5 ng/mL) were higher than maternal values (128 ng/mL). A significant proportion of term SGA infants deve-loped anemia during early infancy, irrespective of maternal iron status.

Relationship between Placental Pathology and Birth Weight of Newborns at a Tertiary Care Centre in Central Kerala, India: A Cross-sectional Study

Introduction: Even minor changes in the placenta are associated with the mortality and morbidity of the growing foetus and mother, which may have long-standing effects on the foetus. Aim: To study the relationship between placental pathological changes and the birth weight of newborn infants. Materials and Methods: In this cross-sectional study conducted at Malankara Orthodox Syrian Church (MOSC) Medical College, Kolenchery, Ernakulam, Kerala, India, over a period of two months, all inborn neonates, irrespective of gestational age, were considered. The first 63 placental samples (with birth weight &lt;2.5 kg) were taken as cases, and the immediately succeeding next 63 were taken as controls (birth weight &gt;2.5 kilograms). At birth, neonatal details including birth weight, gestational age, placental weight, Small for Gestational Age (SGA)/ Appropriate for Gestational Age (AGA)/Large for Gestational Age (LGA), etc., were noted. The placentae were carefully removed, weighed before fixation, and subjected to pathological examination (including gross and microscopic examination). Data were analysed using Statistical Package for the Social Sciences (SPSS) version 14.0 software by Chi-square test. Results: A total of 126 placentae were examined. Increased fibrin deposition in the placenta (perivillous, intervillous, or subchorionic) was associated with Low Birth Weight (LBW) neonates (p-value=0.024), but infarcts were not. Increased fibrin deposition in the placenta (p-value=0.016) and infarcts in the placenta (p-value=0.02) were associated with SGA neonates. However, other findings like haemorrhage, thrombus, calcification, metaplasia, necrosis, vasculopathy, infections, fibrosis, vasculitis were not found to be associated with LBW or SGA neonates. There was a moderate positive correlation between placental weight and the birth weight of neonates (r-value=0.59). Conclusion: Abnormal histopathological changes like infarcts and fibrin deposition in the placenta result in LBW infants. Therefore, proper antenatal screening of the mother for immunology-based rejection-like disorders, maternal coagulopathies, and imbalances between angiogenic or antiangiogenic pathways is necessary. Regular follow-up of infants with placental pathological changes are also essential.

A Study on Incidence, Pattern of Clinical Features, Laboratory Abnormalities and Outcome of Neonatal Polycythaemia in a Tertiary Care Hospital, Odisha, India

Introduction: Neonatal polycythaemia is a commonly encountered morbidity and mortality among neonates admitted to neonatal care units and sick newborn care units. Most affected infants have no clinical symptoms and signs, but neonates may present with lethargy, poor feeding, plethora, cyanosis and jaundice within 12-72 hrs. Aim: To find out the incidence and clinical manifestations of neonatal polycythaemia along with detection of disease by laboratory abnormalities. Materials and Methods: This was a hospital-based, prospective, observational study conducted in the Neonatal Care Unit of Sriram Chandra Bhanja Medical College, Eastern Odisha, India, in 1760 neonates, from October 2018 to September 2020. All neonates admitted through Outdoor and Emergency were included in this study irrespective of gestation, birth weight, maturity and mode of delivery with haematocrit &gt;65% at 12 hours of life. These polycythaemic babies were further categorised on the basis of maturity, gestational age, birth weight, gender and the clinical features, laboratory abnormalities were noted, Partial Exchange Transfusion (PET) when required was done through central route, the umbilical venous catheter was used for withdrawing blood while same amount of normal saline was replaced through a peripheral vein, and in asymptomatic cases additional fluid of 20 mL/kg was added to the daily fluid requirements either through enteral or parenteral route and outcomes were noted. Short-term outcome at 48 hours was measured by decreasing haematocrit with improvement of signs and symptoms. Chi-square test was employed to analyse the collected data using Statistical Package for the Social Sciences (SPSS) software version 20.0. The p-value &lt;0.05 was considered statistically significant. Results: Out of 1760 newborns enrolled, (n=75) were polycythaemic. The Incidence of polycythaemia was 4.26%), which was significantly higher among Small for Gestational Age (SGA) compared to Large for Gestational Age (LGA) neonates (p-value=0.0214). Clinical features in decreasing order were lethargy (66.6%), poor feeding (66.6%), Plethora (53.3%), cyanosis (40%) and jaundice (33.3%). Main laboratory abnormalities were hypoglycaemia (36%), hyperbilirubinaemia (28%), thrombocytopenia (22.66%) and hypocalcaemia (13.3%). Out of 75 polycythemic neonates, n=17 (22.67%) underwent PET and rest 58 (77.33%) neonates were treated with extra fluid of 20 mL/kg/day. Conclusion: Study showed that lethargy and poor feeding were the main presentation and hypoglycaemia as the major laboratory abnormality. The incidence of polycythaemia was high among SGA neonates and the response to partial exchange transfusion as well as extra fluid was good which was characterised by decreasing haematocrit values with improvement of signs and symptoms.
