This article proposes that machine learning can break through the technical limitations of the linear growth test for the early physique of infants smaller than gestational age and can accurately calculate and predict the consequences of the disease. For testing the linear growth of the early physique of infants smaller than gestational age, the data collection and judgment are carried out according to the computer analysis method. Experimental results show that 47.3% of infants younger than gestational age may have suffocation. The experimental subjects designed in this study are small-for-gestational-age infants who were hospitalized in the neonatal intensive care unit from January 2020 to January 2021. According to the relationship between gestational age and birth weight, the survey subjects were divided into two groups: early group and late group. Male and female small-for-gestational-age infants accounted for 68% and 32%, respectively. Among them, the proportion of early gestational age was the most, with more boys than girls, and sick singleton was more than twins. In the early group, the incidence was 52.1% for neonatal asphyxia, 22.5% for feeding intolerance, 14.8% for intracranial hemorrhage, 6.3% for scleredema, 24.7% for neonatal hyperbilirubinemia, 24.6% for hypoglycemia, 1.1% for apnea, and 3.2% for respiratory distress syndrome. Infants develop differently at different stages of corrected gestational age. The incidence of low body weight (6%) after correction for 3 months was significantly reduced compared with correction for gestational age, and the difference was statistically significant ( P  < 0.05). The nutrient absorption of infants younger than gestational age can promote physical catch-up growth, physical development, and neurodevelopment. Therefore, the physical growth of infants younger than gestational age requires supplementation that focuses on nutrition.

<b><i>Objective:</i></b> This study aimed to assess reduced fetal growth between 35 weeks of gestation and birth in non-small for gestational age fetuses associated with adverse perinatal outcomes (APOs). <b><i>Material and Method:</i></b> It is a retrospective cohort study of 9,164 non-small for gestational age fetuses estimated by ultrasound at 35 weeks. The difference between the birth weight percentile and the estimated percentile weight (EPW) at 35 weeks of gestation was calculated, and we studied the relationship of this difference with the appearance of APO. APOs were defined as cesarean or instrumental delivery rates for nonreassuring fetal status, 5-min Apgar score &#x3c;7, arterial cord blood pH &#x3c;7.10, and stillbirth. Fetuses that exhibited a percentile decrease between both moments were classified into 6 categories according to the amount of percentile decrease (0.01–10.0, 10.01–20.0, 20.01–30.0, 30.01–40.0, 40.01–50.0, and &#x3e;50.0 percentiles). It was evaluated whether the appearance of APO was related to the amount of this percentile decrease. Relative risk (RR) was calculated in these subgroups to predict APOs in general and for each APO in particular. Receiver operating characteristic and area under curves (AUC) for the difference in the percentile was calculated, used as a continuous parameter in the entire study population. <b><i>Results:</i></b> The median gestational age at delivery in uncomplicated pregnancies was 40.0 (39.1–40.7) and in pregnancies with APOs 40.3 (49.4–41.0), <i>p</i> &#x3c; 0.001. The prevalence of APOs was greater in the group of fetuses with a decrease in percentile (7.6%) compared to those with increased percentile (4.8%) (<i>p</i> &#x3c; 0.001). The RR was 1.63 (95% CI: 1.365–1.944, <i>p</i> &#x3c; 0.001). Although the differences were significant in all decreased percentile groups, RRs were significantly higher when decreased growth values were &#x3e;40 points (RR: 2.036, 95% CI: 1.581–2.623, <i>p</i> &#x3c; 0.001). The estimated value of the AUC for percentile decrease was 0.58 (0.56–0.61, <i>p</i> &#x3c; 0.001). <b><i>Conclusion:</i></b> Fetuses with a decrease in the EPW between the ultrasound at 35 weeks of gestation and birth have a higher risk of APOs, being double in fetuses with a decrease of &#x3e;40 percentile points.

PURPOSE: To study the incidence of retinopathy of prematurity (ROP) in a neonatal intensive care unit in Croatia and obtain information on risk factors associated with ROP. There have been limited studies on ROP in Croatia where the screening for ROP and its treatment is still insufficient and not introduced in many intensive care units. MATERIAL AND METHODS: This retrospective study included 247 premature infants admitted to the neonatal intensive care unit of University Hospital Split, over a 5-year period between January 2012, and December 2016. In this paper the relationship between clinical risk factors and the development of ROP was analyzed. RESULTS: The overall incidence for ROP was 23,9 % (59 infants), for Type 1 ROP was 9,3% (23 infants); for Type 2 ROP was 14,6% (36 infants). Median gestational age (GA) and birthweight (BW) were significantly lower among infants with ROP versus those without ROP (29: 23-34 vs. 31: 23-34,p<0,001 and 1,180:630-2,000 vs. 1485:590-2000, p<0,001 respectively). Multivariate analysis showed that only BW (p=0,029) and small for gestational age (SGA) (p=0,045) predicted the development of ROP. CONCLUSION: Birth weight and small for gestational age were the most significant risk factors for developing ROP. In comparison with studies from highly developed countries, infants with a much wider range of gestational age and birth weights are developing Type 1 ROP.

Marriage has been associated with improved pregnancy outcomes. However, as Americans become increasingly accepting of pregnancy and childbearing outside of marriage, many believe the father can support the mother without the parents being married. Some question whether the present normalization of childbearing outside of marriage will negate the protective effect of marriage on pregnancy outcomes. Data from the Centers for Disease Control and Prevention Pregnancy Risk Assessment Monitoring System were used to obtain data from a sample of 138,118 live singleton deliveries from 2012 to 2014. Odds ratios were compared between married and unmarried mothers for outcomes of preterm delivery, a small for gestational age infant, neonatal intensive care unit admission, vaginal delivery, and breastfeeding initiation. Logistic regression analyses were used to adjust for maternal age, maternal and paternal race, maternal medical comorbidities, maternal smoking status, and receipt of Medicaid. Adjusted odds ratios (AOR) showed married women had a lower risk of preterm delivery (AOR = .877, 95% confidence interval [CI; .811–.948]), a small for gestational age baby (AOR = .838, 95% CI [.726–.967]), and a neonatal intensive care admission (AOR = .808, 95% CI [.754–.866]). Women who were married were more likely to have a vaginal delivery (AOR = 1.144, 95% CI [1.085–1.211]) and to initiate breastfeeding (AOR = 1.601, 95% CI [1.490–1.719]). These data demonstrate that despite a normalization in society of childbearing outside of marriage, there continues to be an association of marriage with improved birth outcomes. Summary: Marriage is associated with a lower risk of preterm delivery, small for gestational age infants, and neonatal intensive care unit admission. These differences persist even after correcting for potentially confounding socioeconomic factors.

Abstract Objectives To compare cardiac structural and functional findings of fetuses with fetal growth restriction (FGR) and small for gestational age (SGA). Methods In this prospective cohort study, patients were classified into three groups using Delphi procedure according to fetal weight, umbilical, uterine artery Doppler and cerebroplacental ratio. Fetal cardiac ultrasonographic morphology and Doppler examination was performed to all pregnant women at 36 weeks of gestation. Results Seventy three patients were included in the study. There were one (6.7%) patient in the control group, 2 (13.3%) in the SGA group and 12 (80%) in the FGR group who needed neonatal intensive care unit (NICU) and NICU requirement was significantly higher in FGR fetuses (p<0.001). Left spherical index was found to be lower only among FGR fetuses (p=0.046). Left ventricular wall thickness was decreased and the right/left ventricular wall ratio was increased in FGR fetuses (p=0.006, p<0.001). Tricuspid/mitral valve ratio and mitral annular plane systolic excursion value was lower in FGR fetuses (p=0.034, p=0.024 respectively). Also, myocardial performance index was remarkably higher in FGR group (p=0.002). Conclusions We detected cardiac morphological changes in cases of both SGA and FGR—more pronounced in the FGR cases. Findings related to morphological changes on the left side in FGR cases were considered secondary to volume increase in FGR cases as an indicator of a brain-protective effect. In the FGR group, both systolic and diastolic dysfunctions were detected in the left heart.

Background Small for gestational age (SGA) has been associatedwith adult cardiovascular disease. Small for gestational agenewborns may undergo early aortic wall intima-media thickening(aIMT) in utero.Objective To determine the relationship between SGA as a riskfactor for increased aIMT, as a sign of atherosclerosis onset.Methods We conducted a case-control study in the Neonatal Wardand Rooming-in Nursery at Dr. Mohammad Hoesin Hospital,Palembang, between April to June 2012. Subjects were allocatedto either the case group (aIMT 2: 0.9 mm) or to the controlgroup (aIMT <0.9 mm). Newborns were classified as SGA iftheir birthweight (BW) was < l O'h percentile, and appropriatefor gestational age (AGA) if their BW was between lQth - 90'hpercentile, according to the Lubchenco curve. Abdominal aorticintima-media thickness was measured by echocardiographyexamination.Results The case and control groups consisted of 30 n ewbornseach. The proportion of SGA newborns was higher in the casegroup than the control group. The likelihood of infants in the casegroup being SGA was significantly higher compared to the controlgroup, with odds ratio of 10.8 (95%CI 3,26 to 35, 72) . The meanaIMT was significantly higher in SGA than in AGA infants, 0.9(SD 0.16) mm vs. 0.8 (SD 0.13) mm, respectively, with a meandifference of 0, 13 (9 5% CI 0, 050 to 0,209 mm; P"" 0,02).Conclusion Increased aIMT is more likely found in SGA newborns.

BackgroundAbout 10-15% small-for-gestational-age children are in higher risk for having linear growth retardation due to growth hormone-insulin like growth factor 1 axis defect (GH-IGF 1) which causes bone age delay.ObjectivesTo compare bone age in 24-36 month old children born small-for-gestational-age (SGA) to that in children born appropriate-for-gestational-age (AGA).MethodsA cross-sectional study was conducted in Hasan Sadikin General Hospital, Bandung, from January to April 2009.Subjects consisted of50 healthy children of 24-36 months old (25 children born at term, SGA, 25 children born at term, AGA). We compared the appropriateness and delay of bone age between the two groups. ResultsMean bone age in the SGA group was 20.8 (SD 7.7) months, and in the AGA group was 25.7 (SD 7.1) months (P=0.022). Mean bone age deficit was -10.5 (6.5) months in the SGA group and -5.5 (SD 5.7) months in the AGA group (P=0.009). The prevalence ratio was 1.77 (95% CI: 1.19–2.62). Bone age delay was found to be higher in children born SGA than that in children of the other group (23 vs 13). On the contrary, appropriate bone age was found more in children born AGA (12 vs 2) (P=0.002).Conclusion Bone age delay in 24-36 months old children born small-for-gestational-age was found to be higher than in those born appropriate-for-gestational-age.

ContextThe association between small for gestational age (SGA) and retinopathy of prematurity (ROP) is unclear.ObjectiveA systematic review and meta-analysis was conducted to evaluate the association between ROP and SGA in preterm infants <37 weeks’ gestational age (GA) admitted to neonatal intensive care unit.MethodsMedline, PubMed, Web of Science and Cochrane Central databases were searched from inception through 15 January 2019. Studies reporting outcomes based on SGA as the primary exposure variable were included. Data were extracted independently by two coauthors. Modified Newcastle-Ottawa scale was used for risk of bias assessment.ResultsDatabase search yielded 536 records (Medline=152, PubMed=171, Web of Science=144 and Cochrane Central=69). Twenty-one studies evaluating 190 946 infants were included. SGA was associated with significantly higher odds of any stage of ROP on unadjusted analysis (unadjusted OR (uOR) 1.55; 95% CI 1.22 to 1.98; 10 studies) but not on adjusted analysis (adjusted OR (aOR) 2.16; 95% CI 0.66 to 7.11; 3 studies). SGA was associated with significantly higher odds of severe ROP (aOR 1.92; 95% CI 1.57 to 2.34; nine studies). SGA was also significantly associated with higher odds of treated ROP (aOR 1.39; 95% CI 1.18 to 1.65; three studies). In subgroup analysis of infants <29 weeks’ GA, SGA was significantly associated with increased odds of ROP (uOR 1.64; 95% CI 1.19 to 2.26; two studies), severe ROP (aOR 1.61; 95% CI 1.23 to 2.10; four studies) and treated ROP (aOR 1.37; 95% CI 1.16 to 1.62; two studies).ConclusionSGA was associated with increased odds of any stage of ROP, severe ROP and treated ROP in preterm infants. Neonatologists should incorporate SGA into the risk assessment during ROP evaluation and while providing counselling to the families of preterm SGA infants. ROP screening guidelines should look into the frequency of follow-up examination in SGA infants in aim to offer early detection and treatment.
