RESUMO

OBJECTIVE: To evaluate the optimal timing for fetal weight estimation during the third trimester. METHODS: This retrospective cohort study involved fetal weight estimations from both early (28+0-36+6 weeks) and late (37+0 weeks and beyond) third trimester. These estimations were converted to predicted birth weights using the gestation-adjusted projection formula. Birth weight predictions were compared with actual birth weights, to identify the most effective timing for weight prediction. RESULTS: The study included 3549 cases, revealing mean percentage errors (MPE) of -3.69% for early sonographic assessments, -2.5% for late sonographic assessments, and -1.9% for late clinical assessments. A significant difference was found between early and late sonographic estimations (P < 0.001), whereas late sonographic and clinical assessments did not differ significantly (P = 0.771). Weight predictions for fetuses below the 10th and above the 90th centiles were less accurate than for those within the 10th-90th centiles (P < 0.001). In women with obesity, late clinical estimations were less precise (MPE of -5.85) compared with non-obese women (MPE of -1.66, P < 0.001). For women with diabetes, early sonographic estimations were more accurate (MPE of -1.31) compared with non-diabetic patients (MPE of -3.94, P < 0.001) though this difference did not persist later in pregnancy. CONCLUSION: Sonographic and clinical weight predictions in the late third trimester were more accurate than earlier third-trimester sonographic assessments, hence continuous follow up and assessments closer to term are important. In women with diabetes, no adjustments in weight prediction methods are necessary. Accurately predicting birth weights for abnormally small or large fetuses remains challenging, indicating the need for improved screening and diagnostic strategies.

RESUMO

OBJECTIVE: This study aimed to compare the neuropsychological function in early adolescence between children born small for gestational age (SGA) or large for gestational age (LGA) and those born appropriate for gestational age (AGA). METHODS: This retrospective cohort study utilized data from the Adolescent Brain Cognitive Development study in 2016-18. Children born of singleton pregnancy with complete information of birth weight and delivery week were enrolled. Their neuropsychological functioning were assessed by the brain structural magnetic resonance imaging (MRI), combined with cognitive and behavioral measurements. Linear mixed-effects models and subgroup analyses were performed. RESULTS: Among 5,922 children aged 9-11, children born SGA and LGA demonstrated similar cognitive and behavioral performances as children born AGA (P > 0.05). In the MRI measurement, brain area and volume were lower among SGA children compared to AGA children (t=-5.626, Cohen's d = 0.448, P < 0.001; t=-6.071, Cohen's d = 0.427, P < 0.001); brain area and volume were higher among LGA children compared to AGA children (t = 8.562, Cohen's d = 0.470, P < 0.001; t = 8.562, Cohen's d = 0.470, P < 0.001). Cortical thickness was of no statistical difference (P > 0.05). These associations were confirmed by sensitivity analyses and propensity score matching. CONCLUSION: Children born of SGA and LGA status were associated with altered brain area and volume structure in early adolescence.

RESUMO

Children born small for gestational age (SGA) are defined as those having birth weight and/or length below -2 SD for gestational age. In approximately 90% of cases, SGA children experience catch-up growth in the first two years of life and a subsequent regular growth rate, reaching normal adult height. However, in the remaining 10% of cases, SGA children fail to have catch-up growth, showing persistent short stature and a constantly impaired growth rate, leading to decreased adult height compared with both general population and their mid-parental height. Therefore, in these children GH treatment may be indicated to improve growth outcome. As it can be started in most countries from the age of 4 years and is usually recommended until the completion of puberty, long-term GH treatment in SGA children (namely, longer than three years) showed a persistent improvement in height and an initial improvement in growth rate in the first year of treatment, followed by a stable, regular growth rate over time. In the present article, we systematically reviewed the currently available reports about efficacy of long-term GH treatment in SGA children, with a particular focus on growth rate over time and adult height.

RESUMO

CONTEXT: Somapacitan, a once-weekly reversible albumin-binding GH derivative, is evaluated in short children born small for gestational age (SGA). OBJECTIVE: Evaluate efficacy, safety, tolerability as well as total and bioactive insulin-like growth factor-I (IGF-I) response of once-weekly somapacitan compared to daily GH in children born SGA. METHODS: REAL5 is a randomized, multi-center, open-label, controlled phase 2 study comprising a 26-week main phase, 26-week extension, and an ongoing 4-year safety extension (NCT03878446). SETTING: Thirty-eight sites across 12 countries. PATIENTS: Sixty-two GH-treatment-naïve, prepubertal short children born SGA were randomized; 61 completed 52-weeks of treatment. INTERVENTIONS: Patients randomized (1:1:1:1:1) to somapacitan (0.16, 0.20 or 0.24 mg/kg/week) or daily GH (0.035 or 0.067 mg/kg/day), all administered subcutaneously. RESULTS: Estimated mean height velocity (HV; cm/year) at week 52 was 8.5, 10.4 and 10.7 cm/year for somapacitan 0.16, 0.20 and 0.24 mg/kg/week, respectively, and 9.3 and 11.2 cm/year for daily GH 0.035 and 0.067 mg/kg/day, respectively. Dose-dependent increases in total IGF-I as well as peak IGF-I bioactivity were observed for both treatments and were similar between comparator groups. For somapacitan, exposure-response modelling indicated highest efficacy with 0.24 mg/kg/week after 52 weeks of treatment. Similar safety and tolerability were demonstrated across all groups. CONCLUSIONS: A sustained dose-dependent growth response was demonstrated for somapacitan after 52 weeks of treatment. Overall, somapacitan 0.24 mg/kg/week provides similar efficacy, safety, and tolerability, as well as comparable bioactive and total IGF-I response, as daily GH (0.067 mg/kg/day) in children born SGA.

RESUMO

OBJECTIVE: The aim of the present study was to evaluate the obstetric complications associated with isolated fetal congenital heart disease (CHD) by comparing pregnancies with and without this condition. METHODS: In this retrospective matched comparative study at Siriraj Hospital, Thailand, we included 233 postnatally confirmed fetal CHD cases and 466 unaffected fetuses. Controls were selected at a 2:1 ratio, ensuring that they matched the cases in terms of maternal age, parity, and history of preterm deliveries. RESULTS: Fetal CHD was significantly associated with an increased risk of spontaneous preterm labor (30% vs 9.7%; adjusted odds ratio [aOR] 2.42; 95% confidence interval [CI]: 1.35-4.36; P = 0.003), delivery before 34 gestational weeks (11.6% vs 0.6%; aOR 12.33; 95% CI: 3.32-45.78; P < 0.001), and pre-eclampsia (11.6% vs 2.8%; aOR 2.19; 95% CI: 1.01-4.76; P = 0.047). Newborns with CHD were significantly more likely to be small for gestational age (10.7% vs 5.2%; aOR 2.09; 95% CI: 1.11-3.94; P = 0.022). Intriguingly, a prenatal diagnosis of CHD was associated with a reduced risk of preterm delivery in affected pregnancies (P = 0.002). CONCLUSION: Pregnancies affected by isolated fetal CHD demonstrated a higher propensity for several adverse outcomes. These findings underscore the importance of prenatal CHD detection and tailored perinatal care to potentially improve both pregnancy outcomes and neonatal health.

RESUMO

BACKGROUND: Limited English proficiency is associated with worse health outcomes regardless of health literacy. Prior research suggests that using interpreter services for low English proficiency helps mitigate the language barrier, is associated with improved health outcomes, and patient satisfaction; however, obstetric and neonatal outcomes and pregnancy risks in this population are not well studied. OBJECTIVES: The primary purpose of this study was to determine if low English proficiency is an independent risk factor for small for gestational age infants by utilizing interpreter use as a proxy for low English proficiency. Due to the known challenges in communication with a language barrier and discrimination against people whose first language is not English, we hypothesized that this could result in an increase in high risk conditions in pregnancy such as SGA. Our hypothesis was that the need for an interpreter would be associated with having small for gestational age infants. STUDY DESIGN: We performed a retrospective cohort study at a single center using data between 1/1/2016 and 12/31/2021; we included singleton, live births ≥21 weeks gestation. We excluded multiple gestations, intrauterine fetal demise, and delivery <21 weeks. The primary outcome was rate of small for gestational age. Small for gestational age was defined as birthweight < 10th percentile for gestational age using the 2018 Fenton newborn growth curve. Multivariable logistic regression was performed to control for confounding variables. RESULTS: Of the 26,260 patients included in the study, 71.3% were non-Hispanic White, 9.5% were Hispanic/Latino, and 7.9% were non-Hispanic Black. Overall, 1,662 (6.3%) patients utilized an interpreter. Over half (58.0%) of patients requesting interpreter services were Hispanic. In unadjusted analyses, the rate of small for gestational age was not different between patients who used interpreter services (n = 106, 6.4%) and those who did not (n = 1612, 6.6 %), p = 0.779. After adjusting for race/ethnicity, gravidity, gestational age, private insurance, diabetes, hypertension, and pre-pregnancy body mass index, the use of interpreter services was associated with decreased odds of small for gestational age (aOR 0.67, 95% CI 0.53 - 0.84). CONCLUSIONS: Our findings suggest that use of an interpreter is associated with a lower incidence of small for gestational age when controlling for patient characteristics and social determinants of health. Additional research is required to explore this association, but our results indicate that recognizing demographic risk factors and providing patients with social resources such as access to interpreter services may positively impact obstetric and neonatal outcomes.

RESUMO

BACKGROUND: Prehypertension during pregnancy is currently not considered as a high-risk pregnancy state in existing guidelines despite recent research correlating it with higher rates of morbidity and mortality in both the mother and the fetus. Studies on prehypertension have not been conducted in Africa despite high rates of poor neonatal outcomes. AIMS: The study aimed to determine the association between late pregnancy prehypertension and adverse outcomes in newborns of women with late pregnancy prehypertension at Jinja Regional Referral Hospital. METHODS AND MATERIALS: Between September 2022 and January 2023, a hospital-based prospective cohort study including 300 pregnant women was conducted. Participants were divided according to third-trimester blood pressure, as determined by the JNC-8 criteria. Following hospital admission for labor and delivery, 150 normotensive women and 150 prehypertensive women were identified and followed until delivery, and their neonates were followed until death or hospital discharge. A p value of ≤ 0.05 was the threshold for statistical significance when comparing the groups using the relative risk, X2, and Mantel-Haenszel adjustment. RESULTS: Composite adverse neonatal outcomes were more common in prehypertensive women compared to normotensive women (48.67% versus 32.67%), particularly Small-for-Gestation Age (SGA), stillbirth, and composite adverse neonatal outcomes had significantly higher likelihood, with aRRs of 1.63 (95% CI 1.10-2.42, p = 0.037), 9.0 (95% CI 1.15-70.16, p = 0.010), and 1.55 (95% CI 1.16-2.08, p < 0.001), respectively. By a linear model, birthweight decreased by 45.1 g for every 10 mmHg rise in systolic blood pressure (p = 0.041, Pearson correlation of -0.118). CONCLUSION AND RECOMMENDATIONS: Prehypertension in late pregnancy increased risks for adverse neonatal outcomes, thus a need to potentially lower pregnancy hypertension cut-off levels possibly through adopting the ACC/AHA blood pressure definitions for pregnant women.

RESUMO

Abstract Objective: To study the association between placental efficiency with anthropometry and nutritional phenotypes in full-term newborns from a birth cohort. Method: This was a secondary cross-sectional analysis of data obtained in a cohort study (Brazilian RibeirãoPreto and São Luís Birth Cohort Studies - BRISA), whose deliveries were performed between 2010 and 2011. Standardized questionnaires were applied to mothers, and placentas and newborns were evaluated shortly after delivery. Placental efficiency was assessed using the ratio between birth weight and placental weight (BW/PW ratio); values below the lower quartile (25th percentile for gestational age) were considered to have low placental efficiency. Newborn phenotypes were small and large for gestational age, stunted and wasted, evaluated using the INTERGROWTH-21 growth standard. To identify the confounding variables theoretical model was constructed using Directed Acyclic Graphs, and unadjusted and adjusted logistic regression were performed. Placental measurements were obtained blindly from pregnancy and delivery data. Results: 723 mother-placenta-child triads were studied. 3.2 % of newborns were small-for-gestational-age (SGA), 6.5 %large-for-gestational-age (LGA), 5.7 %had stunting, and 0.27 % wasting. A significantly higher risk was found between low placental efficiency and SGA (OR 2.82;95 % CI 1.05-7.57), stunting (OR 2.23; 95 % CI 1.07-4.65), and wasting (OR 8.22; 95 % CI 1.96-34.37). No relationship was found between LGA and placental efficiency. Conclusions: Low placental efficiency was associated with increased risk for small-for-gestational-age, stunting, and wasting. Placental morphometry can provide valuable information on intrauterine conditions and neonatal health, helping to identify newborns at higher risk of future comorbidities.

RESUMO

BACKGROUND: Small for gestational age (SGA) neonates are known to be at an elevated risk for neonatal morbidity. Despite this, there is a growing array of proposed size standards for identifying SGA fetuses. Given the inherent differences in design, acquisition methods, and the characteristics of the populations they represent, the generalizability of these standards to diverse populations remains uncertain. INTRODUCTION: This study aimed to assess variations in rates of SGA and severe SGA using six distinct size standards: Hadlock, Fetal Medicine Foundation (FMF), World Health Organization (WHO), Intergrowth-21 (IG-21), and two locally derived population-based size standards. The objective was to examine the differences in SGA and severe SGA rates among these size standards. METHODS: A retrospective cohort study was conducted, encompassing all singleton deliveries in two tertiary referral hospital campuses with an annual birth count exceeding 10,000, from January 2019 to July 2022. SGA and severe SGA were defined as birthweights below the 10th or 3rd percentile, respectively, based on each growth standard. The study design included details on the setting, subjects (singleton deliveries), and the chosen size standards. Comparative analyses were performed to assess variations in SGA and severe SGA rates among these size standards. RESULTS: Our study analyzed 32,912 singleton deliveries. We found that the choice of growth standard significantly impacted the rates of both SGA and severe SGA infants. Notably, the WHO criteria identified 5,548 (16.9 %) fetuses as SGA, compared to only 1,716 (5.2 %) using the INTERGROWTH-21 standard (p < 0.001). Similarly, for severe SGA, the FMF charts classified 2098 (6.37 %) infants, significantly higher than the 320 (1 %) identified by Dolberg's local population-based charts (p < 0.001). CONCLUSION: Our study demonstrates a significant variety of SGA and severe SGA rates using different size standards. Therefore, the decision on the size standards in use is critical given the significant influence on clinical management. SYNOPSIS: There are significant variations in SGA and Severe SGA rates depending on the chosen size standard.

RESUMO

OBJECTIVES: Up to a quarter of pregnant individuals with systemic lupus erythematosus (SLE) have small for gestational age (SGA) infants. We aimed to characterize placental pathology associated with SGA infants in SLE. METHODS: We retrospectively analyzed SLE deliveries with placental analysis at UCSD from 11/2018-10/2023, comparing SLE pregnancies resulting in SGA to those that did not, and additionally, to matched pregnancies with SGA but without SLE. RESULTS: Placental analysis was available only for 28/70 (40%) SLE deliveries, which had high rates of adverse outcomes (75%). All exhibited at least one histopathologic abnormality. Key findings distinguishing 12 SLE placentas resulting in SGA infants (vs.16 without) included small placental disc for gestational age (100% vs 56%, p= 0.01), placental disc infarct (50% vs 6%, p= 0.02), and increased perivillous fibrin deposition (PVFD, 58% vs 0%, p= 0.001). All seven SLE placentas with increased PVFD resulted in SGA infants. Compared with matched non-SLE pregnancies with SGA (n = 36), the only distinguishing placental lesion was a higher prevalence of increased PVFD in SLE-associated SGA (58% vs 22%, p= 0.03). CONCLUSION: The higher prevalence of increased PVFD in placentas of SLE-associated SGA may indicate a specific mechanism of placental injury leading to SGA in this context. Thus, its presence, particularly in context of SGA, should prompt providers to screen for an underlying autoimmune disease, including SLE. Systematic placental examination in context of SLE and associated autoimmune diseases could help evaluate responses to existing therapies, comparative studies of novel therapies, and correlation to adverse outcomes.

RESUMO

Vitamin E is associated with the regulation of lipid metabolism. Our previous study revealed an inverse relationship between birth weight and cord blood vitamin E levels, suggesting a potential link between vitamin E and fetal growth. The aim of this study was to determine the association between vitamin E with fetal growth and lipids. In this investigation, a study involving 146 mother-infant pairs was performed. Cord plasma concentrations of vitamin E and lipids were measured. Our findings showed that cord plasma vitamin E levels were elevated in small for gestational age (SGA) infants, and higher vitamin E levels were associated with an increased risk of SGA (OR = 2.239, 95% CI 1.208, 4.742). Additionally, among lipid levels, higher cord plasma triglyceride (TG) levels were associated with increased risks of SGA (OR = 97.020, 95% CI 5.137, 1832.305), whereas after adjusting for confounding factors, the risk became no longer statistically significant. We also found a positive correlation between cord blood vitamin E concentrations and lipid levels. CONCLUSION:  elevated cord blood vitamin E concentrations may be associated with a higher risk of SGA and are positively correlated with lipid levels, suggesting a potential role for vitamin E in fetal lipid metabolism. WHAT IS KNOWN: • Vitamin E is associated with the regulation of lipid metabolism. • Vitamin E is inversely related to birth weight. WHAT IS NEW: • Elevated cord blood vitamin E concentrations may be associated with a higher risk of SGA and positively correlated with lipid levels.

RESUMO

INTRODUCTION: Limited evidence exists on borderline oligohydramnios. Our objective was to determine perinatal outcomes in uncomplicated term pregnancies with borderline oligohydramnios. METHODS: This retrospective analysis compared adverse perinatal outcomes among pregnancies during 2018-2022, between those with borderline oligohydramnios defined as amniotic fluid index (AFI) of 5.1-8.0 cm, those with oligohydramnios (AFI ≤5 cm), and those with normal AFI (8.1-25 cm). The latter matched one-to-one to the borderline oligohydramnios group and served as the control group. The outcomes compared included birthweight, cesarean delivery due to fetal distress, the presence of meconium-stained amniotic fluid, Apgar scores, neonatal intensive care unit admission, and the occurrence of small-for-gestational-age (SGA) neonates. RESULTS: During the study period, 140 women had borderline oligohydramnios and 345 had oligohydramnios; the control group included 140 women. Borderline oligohydramnios was associated with increased rates of delivering SGA neonates (adjusted odds ratio [aOR] = 3.6, 95% confidence interval [CI] 1.1-11.6, p = 0.034) and cesarean delivery due to fetal distress (aOR = 3.0, 95% CI 1.1-8.3, p = 0.032). Rates of composite neonatal outcome (including at least one of the following: cesarean delivery due to fetal distress, meconium-stained amniotic fluid, 5-min Apgar score <7, umbilical artery pH <7.15, or neonatal intensive care unit admission) were higher in both the borderline oligohydramnios (20.7%) and oligohydramnios (18.6%) groups compared to the control group (9.3%) (p = 0.019). CONCLUSIONS: Pregnancies with borderline oligohydramnios were associated with increased risks of delivering SGA neonates and requiring cesarean delivery due to fetal distress. These findings support considering closer antepartum surveillance for these pregnancies, especially for identifying abnormal fetal growth.

RESUMO

Objective: To evaluate the mode of delivery according to Robson classification (RC) and the perinatal outcomes in fetal growth restriction (FGR) and small for gestational age (SGA) fetuses. Methods: Retrospective cohort study by analyzing medical records of singleton pregnancies from two consecutive years (2018 and 2019). FGR was defined according to Delphi Consensus. The Robson groups were divided into two intervals (1-5.1 and 5.2-10). Results: Total of 852 cases were included: FGR (n = 85), SGA (n = 20) and control (n=747). FGR showed higher percentages of newborns < 1,500 grams (p<0.001) and higher overall cesarean section (CS) rates (p<0.001). FGR had the highest rates of neonatal resuscitation and neonatal intensive care unit admission (p<0.001). SGA and control presented higher percentage of patients classified in 1 - 5.1 RC groups, while FGR had higher percentage in 5.2 - 10 RC groups (p<0.001). FGR, SGA and control did not differ in the mode of delivery in the 1-5.1 RC groups as all groups showed a higher percentage of vaginal deliveries (p=0.476). Conclusion: Fetuses with FGR had higher CS rates and worse perinatal outcomes than SGA and control fetuses. Most FGR fetuses were delivered by cesarean section and were allocated in 5.2 to 10 RC groups, while most SGA and control fetuses were allocated in 1 to 5.1 RC groups. Vaginal delivery occurred in nearly 60% of FGR allocated in 1-5.1 RC groups without a significant increase in perinatal morbidity. Therefore, the vaginal route should be considered in FGR fetuses.

RESUMO

In patients with proximal hypospadias, often no genetic cause is identified despite extensive genetic testing. Many genes involved in sex development encode transcription factors with strict timing and dosing of the gene products. We hypothesised that there might be recurrent differences in DNA methylation in boys with hypospadias and that these might differ between patients born small versus appropriate for gestational age. Genome-wide Methylated DNA sequencing (MeD-seq) was performed on 32bp LpnPI restriction enzyme fragments after RE-digestion in leucocytes from 16 XY boys with unexplained proximal hypospadias, one with an unexplained XX testicular disorder/difference of sex development (DSD) and twelve, healthy, sex- and age-matched controls. Five of seven differentially methylated regions (DMRs) between patients and XY controls were in the Long Intergenic Non-Protein Coding RNA 665 (LINC00665; CpG24525). Three patients showed hypermethylation of MAP3K1. Finally, no DMRs in XX testicular DSD associated genes were identified in the XX boy versus XX controls. In conclusion, we observed no recognizable epigenetic signature in 16 boys with XY proximal hypospadias and no difference between children born small versus appropriate for gestational age. Comparison to previous methylation studies in individuals with hypospadias did not show consistent findings, possibly due to the use of different inclusion criteria, tissues and methods.

RESUMO

OBJECTIVES: To evaluate the association between adolescent and young adult (AYA) breast cancer (BC) and the adverse pregnancy outcomes of preterm birth, small for gestational age birth, cesarean delivery, and preeclampsia, and the effect of fertility treatment on this association. METHODS: Population-based cohort study with universal coverage health data for Ontario, Canada. BC was identified from the Ontario Cancer Registry. All births >220 weeks gestation between April 2006 to March 2018 were included. Modified Poisson regression generated risk ratios between AYA BC and adverse pregnancy outcomes, adjusted for maternal characteristics. Models were stratified by fertility treatment. RESULTS: Among 1 189 980 deliveries, 474 mothers had AYA BC history (exposed), while 1 189 506 had no cancer history (unexposed). AYA BC was associated with cesarean delivery (adjusted risk ratio [aRR] 1.26; 95% CI 1.14-1.39). There was no association between AYA BC and other adverse outcomes. Modelling cesarean delivery subtypes, AYA BC was associated with increased risk of planned (aRR 1.27; 95% CI 1.08-1.49) and unplanned cesarean delivery (aRR 1.41; 95% CI 1.20-1.66). An increased risk of cesarean delivery in exposed persisted among singleton pregnancies (aRR 1.27; 95% CI 1.15-1.41), but not in models stratified by mode of conception (fertility treatment: aRR 1.07; 95% CI 0.84-1.36; unassisted conception: aRR 1.30; 95% CI 1.16-1.46). CONCLUSIONS: A history of AYA BC did not confer an elevated risk of adverse pregnancy outcomes, except for planned and unplanned cesarean delivery. The risk of adverse pregnancy outcomes does not appear to be an indication for delayed pregnancy after AYA BC diagnosis.

RESUMO

INTRODUCTION: In recent years, there has been a change in the conceptualization of foetal growth restriction (FGR), which has gone from being defined solely based on weight criteria to being defined and staged based on Doppler criteria. The aim of our study was to evaluate neonatal risk in a cohort of neonates with moderate to severe early-onset FGR defined by Doppler criteria. POPULATION AND METHODS: We conducted a multicentre prospective cohort study in a cohort of neonates with early-onset foetal growth restriction and abnormal Doppler findings and a control cohort without Doppler abnormalities matched for sex and gestational age. RESULTS: A total of 105 patients (50 cases, 55 controls) were included. We found a higher frequency of respiratory morbidity in the FGR group, with an increased need of surfactant (30% vs. 27.3%; OR, 5.3 [95% CI, 1.1-26.7]), an increased need for supplemental oxygen (66% vs. 49.1%; OR, 5.6 [95% CI, 1.5-20.5]), and a decreased survival without bronchopulmonary dysplasia (70 vs. 87.3%; OR, 0.16 [95% CI, 0.03-0.99]). Patients with FGR required a longer length of stay and more days of parenteral nutrition and had a higher incidence of haematological abnormalities such as neutropenia and thrombopenia. The lactate level at birth was higher in the severe FGR subgroup (6.12 vs. 2.4 mg/dL; P = .02). CONCLUSION: The diagnosis of early-onset moderate to severe FGR defined by Doppler criteria carries a greater risk of respiratory, nutritional and haematological morbidity, independently of weight and gestational age. These patients, therefore, should be considered at increased risk compared to constitutionally small for gestational age preterm infants or preterm infants without FGR.

RESUMO

Background: The association between maternal fruit consumption and fetal growth remains inconsistent. The current study aimed to determine whether maternal fruit consumption was associated with low birth weight (LBW) or small for gestational age (SGA) babies. Methods: A large birth cohort study was conducted in Lanzhou, China, from 2010 to 2012 and included 10,076 pregnant women at the 1st, 2nd, and 3rd trimester of pregnancy for analysis. Fruit consumption in the 1st, 2nd, and 3rd trimester of pregnancy was measured by a self-designed food frequency questionnaire (FFQ) and divided into three groups: 1) inadequate fruit consumption: <200 g/d for the1st, 2nd, and 3rd trimester; 2) adequate fruit consumption: 200-350 g/d for the 1st trimester or 200-400 g/d for the 2nd and 3rd trimester; 3) excessive fruit consumption: >350 g/d for the 1st trimester or > 400 g/d for the 2nd and 3rd trimester. A case-control study was used to analyze the association between fruit intake during pregnancy and low birth weight infants. Results: Compared to adequate fruit consumption, excessive fruit consumption throughout each trimester of pregnancy was associated with a lower risk of LBW, with an odds ratio (OR) ranging from 0.70 to 0.79 (95 % confidence interval, CI: 0.57-0.98); while inadequate fruit consumption was associated with a higher risk of infant LBW, with an OR ranging from 1.26 to 1.36 (95%CI: 1.04-1.66). After stratifying by mother's pre-pregnancy body mass index (BMI), the results were similar among women with underweight BMI. No significance was found between fruit consumption and SGA in the general population. Still, stratified analyses showed that inadequate fruit consumption was associated with an increased risk of SGA in underweight mothers, with an OR ranging from 1.66 to 1.79 (95%CI: 1.13-2.64). Conclusions: Fruit consumption during pregnancy reduces the risk of LBW in Chinese women, especially in women with low pre-pregnancy BMI.

RESUMO

OBJECTIVES: Atenolol is a commonly used beta bloscker in non-pregnant women. Many providers are hesitant in prescribing atenolol in pregnancy because of a possible association with poor fetal growth. We aimed to assess the association between atenolol and the occurrence of small for gestational age neonates compared to other beta blockers, as described in the existing literature. METHODS: We used the meta-analytic method to generate a forest plot for risk ratios (RR) of small for gestational age in patients who used atenolol vs. other beta blockers. Statistical heterogeneity was assessed with the I2 statistic. RESULTS: Two studies were included, with a resultant RR of 1.94 [95 % confidence interval (CI) 1.60; 2.35]. A study by Duan et al. in 2018 noted the following rate of small for gestational age for each beta blocker use: 112/638 atenolol, 590/3,357 labetalol, 35/324 metoprolol, and 50/489 propranolol. A study by Tanaka et al. in 2016 noted the following rate of small for gestational age: 8/22 for propranolol, 2/12 for metoprolol, 2/6 for atenolol, 0/5 for bisoprolol. Heterogeneity (I2) was 0 %. CONCLUSIONS: Our results suggested an elevated risk of small for gestational age associated with atenolol use in comparison to other beta blockers, specifically labetalol, propranolol, bisoprolol, and metoprolol.

RESUMO

BACKGROUND: Premature and small-for-gestational-age (SGA) infants tend to have long-term growth morbidities such as short stature, failure to thrive, and obesity. Although most of these infants show catch-up growth at 2-4 years of age, they are still more susceptible to childhood obesity and related metabolic disorders. Those who fail to achieve catch-up will suffer from pathological short stature and neurodevelopmental impairment through adulthood. This study aims to depict the growth pattern of premature or SGA infants and their growth morbidities in Taiwan. METHODS: Data were obtained from a nationally representative cohort of 24,200 pairs of postpartum women and newborns in the Taiwan Birth Cohort Study (TBCS), using structured questionnaire interviews. A total of 16,358 infants were included and three follow-up surveys were completed at 6, 18, and 36 months after the deliveries. We constructed growth curves to conduct an in-depth investigation into anthropometric data, applying a linear mixed model. Logistic regression was used to model the relevant outcomes, with adjustment for various potential confounding factors. RESULTS: Despite being born shorter and lighter, preterm and SGA infants generally showed catch-up growth and had no higher odds ratios (ORs) of developing short stature or failure to thrive compared to appropriate-for-gestational-age (AGA) term infants before 3 years of age. Preterm SGA infants, particularly females, had higher ORs for obesity at the 36-month follow-up. CONCLUSION: This is the first nationwide population-based study depicting the growth of SGA infants in Taiwan. The growth patterns of preterm and term SGA infants are different from those of preterm and term AGA infants. Further research is necessary to understand the growth trajectories of preterm and SGA infants and their associations with later diseases.

RESUMO

Recently: more attention has been given to low-birth-weight calves, often without considering gestation length. Calves can be classified as small for gestational age (SGA) when their birth weight is below the 10th percentile, similar to the definition in human medicine. While SGA babies face various health risks, it remains unclear if SGA calves face similar long-term health consequences. This study aimed to investigate the long-term effects on fertility, productive performance, and overall survival in Holstein Friesian (HF) heifers born SGA. Chi-squared analysis assessed culling and survival rates, and linear mixed-effect models evaluated the impact of gestational age group (small, average, or large for gestational age, respectively, SGA, AGA, and LGA) on growth, fertility, milk yield, and lifespan. SGA calves showed catch-up growth at six months but weighed significantly less at twelve months (p = 0.003). Age at first insemination and calving did not differ significantly, although SGA heifers required more inseminations (2.3 ± 1.50) compared to AGA and LGA heifers (1.7 ± 0.98 and 1.5 ± 0.89, respectively, p = 0.006). SGA calves tended to be culled more during the first lactation than AGA calves (25.0% vs. 11.9%, p = 0.078) and showed lower survival to second calving (p = 0.019) compared to AGA and LGA heifers. The Kaplan-Meier analysis indicated a tendency for gestational age to affect overall survival (p = 0.1), with SGA heifers having a higher risk of leaving the herd prematurely (p = 0.035, hazard ratio = 1.53). Milk yield per productive day was significantly lower in SGA heifers (21.2 ± 8.73 kg) compared to AGA and LGA heifers (26.9 ± 5.01 kg and 26.3 ± 3.38 kg, respectively, p = 0.006). This study reveals that HF calves born SGA suffer long-term consequences, although further research is needed to understand the economic impact of rearing SGA heifers.
