RESUMEN

BACKGROUND: Various techniques have been proposed to predict and evaluate the timing and conditions of childbirth in pregnant women at different stages of pregnancy. Providing precise methods for forecasting childbirth status can reduce the burden on the healthcare system. This study aimed to evaluate the predictive value of transvaginal sonography of cervical length (CL) and cervical angle (CA) on full-term delivery outcomes. METHODS: This cohort study analyzed 151 pregnant women between 37 and 42 weeks of gestational age who were treated at Rasoul Akram Hospital affiliated with Iran University of Medical Sciences from June 2023 to January 2024. All Participants received transvaginal examinations. This study evaluated the accuracy of CL and CA by transvaginal sonography in predicting outcomes like vaginal delivery, cesarean section, necessity for labor induction, and the rate of Premature Rupture of Membranes (PROM). The study used the Receiver Operating Characteristic (ROC) curve to determine the optimal cutoff for predicting birth outcomes. RESULTS: The mean age of the pregnant women was 28.9 ± 4.22 years, while the average duration of pregnancy was 39.8 ± 2.11 weeks. Cesarean delivery was performed on 45 individuals (29.8%) and 106 (70.1%) underwent vaginal delivery. The mean CL overall stood at 21.2 ± 6.4 mm. PROM was observed in 41 cases (27.1%) among full-term pregnancies. A significant difference was noted in mean CL between the cesarean and vaginal delivery groups (24.2 ± 2.4 vs. 20.1 ± 2.1 mm, p = 0.001). The predictive value of a CL measuring 21 mm for cesarean delivery was 72.2% sensitive and 79.1% specific. Similarly, a CL of 22 mm showed 66.6% sensitivity and 80.2% specificity for labor induction. Regarding PROM in full-term pregnancies, a CL assessment demonstrated 59.8% sensitivity and 69.1% specificity. Finally, a CA of 115.2° exhibited 70.3% sensitivity and 78.4% specificity in predicting vaginal delivery. CONCLUSION: The present study showed that evaluating CL and CA via transvaginal sonography demonstrated adequate diagnostic accuracy in predicting spontaneous birth, need for labor induction, cesarean delivery, and incidence of PROM in full-term pregnant women. This method is suggested to be an accurate and appropriate way to predict delivery results.

RESUMEN

INTRODUCTION: Rapid growth in early childhood has been identified as a possible risk factor for long-term adiposity. However, there is a lack of studies quantifying this phenomenon only in healthy, full-term infants with appropriate birth weight for gestational age. This systematic review and meta-analysis aimed to investigate the association of rapid growth in full-term children up to 2 years of age with adiposity up to 18 years of age. METHODOLOGY: A systematic review of the literature was conducted in PubMed, EMBASE, and Web of Science. RESULTS: 14 studies were included. We were unable to find strong evidence that rapid growth in early childhood is a risk factor for long-term adiposity. Rapid growth in early childhood was associated with taller heights (standardized mean difference: 0.51 (CI: 0.25-0.77)) and higher body mass index (standardized mean difference: 0.50 (CI: 0.25-0.76)) and a higher risk of overweight under 18 years. CONCLUSION: Rapid growth in early childhood in term infants with appropriate birth weight is associated with higher growth, body mass index, and risk of being overweight up to age 18, but further work is needed to identify the associations between early rapid growth and obesity later in adulthood.

RESUMEN

BACKGROUND: Fetal weight estimation at term is a challenging clinical task. OBJECTIVES: To evaluate the association between peripheral white blood cell (WBC) count of the laboring women and neonatal birth weight (BW) for term uncomplicated pregnancies. METHODS: We conducted a single-center, retrospective cohort study (2006-2021) of women admitted in the first stage of labor or planned cesarean delivery. Complete blood counts were collected at admission. BW groups were categorized by weight (grams): < 2500 (group A), 2500-3499 (group B), 3500-4000 (group C), and > 4000 (group D). Two study periods were used to evaluate the association between WBC count and neonatal BW. RESULTS: There were a total of 98,632 deliveries. The dataset analyses showed a lower WBC count that was significantly and linearly associated with a higher BW; P for trend < 0.001 for women in labor. The most significant association was noted for the > 4000-gram newborns; adjusted odds ratio 0.97, 95% confidence interval 0.96-0.98; P < 0.001; adjusted for hemoglobin level, gestational age, and fetal sex. The 2018-2021 dataset analyses revealed WBC as an independent predictor of macrosomia with a significant incremental predictive value (P < 0.0001). The negative predictive value of the WBC count for macrosomia was significantly high, 93.85% for a threshold of WBC < 10.25 × 103/µl. CONCLUSIONS: WBC count should be considered to support the in-labor fetal weight estimation, especially valuable for the macrosomic fetus.

RESUMEN

During pregnancy, two fetomaternal interfaces, the placenta-decidua basalis and the fetal membrane-decidua parietals, allow for fetal growth and maturation and fetal-maternal crosstalk, and protect the fetus from infectious and inflammatory signaling that could lead to adverse pregnancy outcomes. While the placenta has been studied extensively, the fetal membranes have been understudied, even though they play critical roles in pregnancy maintenance and the initiation of term or preterm parturition. Fetal membrane dysfunction has been associated with spontaneous preterm birth (PTB, < 37 weeks gestation) and preterm prelabor rupture of the membranes (PPROM), which is a disease of the fetal membranes. However, it is unknown how the individual layers of the fetal membrane decidual interface (the amnion epithelium [AEC], the amnion mesenchyme [AMC], the chorion [CTC], and the decidua [DEC]) contribute to these pregnancy outcomes. In this study, we used a single-cell transcriptomics approach to unravel the transcriptomics network at spatial levels to discern the contributions of each layer of the fetal membranes and the adjoining maternal decidua during the following conditions: scheduled caesarian section (term not in labor [TNIL]; n = 4), vaginal term in labor (TIL; n = 3), preterm labor with and without rupture of membranes (PPROM; n = 3; and PTB; n = 3). The data included 18,815 genes from 13 patients (including TIL, PTB, PPROM, and TNIL) expressed across the four layers. After quality control, there were 11,921 genes and 44 samples. The data were processed by two pipelines: one by hierarchical clustering the combined cases and the other to evaluate heterogeneity within the cases. Our visual analytical approach revealed spatially recognized differentially expressed genes that aligned with four gene clusters. Cluster 1 genes were present predominantly in DECs and Cluster 3 centered around CTC genes in all labor phenotypes. Cluster 2 genes were predominantly found in AECs in PPROM and PTB, while Cluster 4 contained AMC and CTC genes identified in term labor cases. We identified the top 10 differentially expressed genes and their connected pathways (kinase activation, NF-κB, inflammation, cytoskeletal remodeling, and hormone regulation) per cluster in each tissue layer. An in-depth understanding of the involvement of each system and cell layer may help provide targeted and tailored interventions to reduce the risk of PTB.

RESUMEN

OBJECTIVE: To develop and evaluate the predictive value of a simplified lung ultrasound (LUS) method for forecasting respiratory support in term infants. METHODS: This observational, prospective, diagnostic accuracy study was conducted in a tertiary academic hospital between June and December 2023. A total of 361 neonates underwent LUS examination within 1 h of birth. The proportion of each LUS sign was utilized to predict their respiratory outcomes and compared with the LUS score model. After identifying the best predictive LUS sign, simplified models were created based on different scan regions. The optimal simplified model was selected by comparing its accuracy with both the full model and the LUS score model. RESULTS: After three days of follow-up, 91 infants required respiratory support, while 270 remained healthy. The proportion of confluent B-lines demonstrated high predictive accuracy for respiratory support, with an area under the curve (AUC) of 89.1% (95% confidence interval [CI]: 84.5-93.7%). The optimal simplified model involved scanning the R/L 1-4 region, yielding an AUC of 87.5% (95% CI: 82.6-92.3%). Both the full model and the optimal simplified model exhibited higher predictive accuracy compared to the LUS score model. The optimal cut-off value for the simplified model was determined to be 15.9%, with a sensitivity of 76.9% and specificity of 91.9%. CONCLUSIONS: The proportion of confluent B-lines in LUS can effectively predict the need for respiratory support in term infants shortly after birth and offers greater reliability than the LUS score model.

RESUMEN

BACKGROUND: Respiratory distress syndrome is a leading cause of neonatal intensive care unit admissions for late preterm (34-36 weeks gestational age) and term infants (37-41 weeks). The risk for respiratory morbidity appears to increase after an elective caesarean delivery and might be reduced after antenatal corticosteroids. However, before considering antenatal corticosteroids for women at high risk of preterm birth after 34 weeks, the incidence of respiratory distress syndrome and the effect of delivery mode on this incidence requires further evaluation. Therefore, this study aimed to investigate the relationship between respiratory distress syndrome incidence and delivery mode in late preterm and term infants. METHODS: In this retrospective cohort study, the clinical databases of the University Hospitals of Zurich and Basel were queried regarding all live births between 34 + 0 and 41 + 6 weeks. Neonatal intensive care unit admissions due to respiratory distress syndrome were determined and analysed in regard to the following delivery modes: spontaneous vaginal, operative vaginal, elective caesarean, secondary caesarean and emergency caesarean. RESULTS: After excluding malformations (n = 889) and incomplete or inconclusive data (n = 383), 37,110 infants out of 38,382 were evaluated. Of these, 5.34% (n = 1980) were admitted to a neonatal intensive care unit for respiratory distress syndrome. Regardless of gestational age, respiratory distress syndrome in infants after spontaneous vaginal delivery was 2.92%; for operative vaginal delivery, it was 4.02%; after elective caesarean delivery it was 8.98%; following secondary caesarean delivery, it was 8.45%, and after an emergency caesarean it was 13.3%. The risk of respiratory distress syndrome was higher after an elective caesarean compared to spontaneous vaginal delivery, with an odds ratio (OR), adjusted for gestational age, of 2.31 (95% CI 1.49-3.56) at 34 weeks, OR 5.61 (95% CI 3.39-9.3) at 35 weeks, OR 1.5 (95% CI 0.95-2.38) at 36 weeks, OR 3.28 (95% CI 1.95-5.54) at 37 weeks and OR 2.51 (95% CI 1.65-3.81) at 38 weeks. At 39 weeks, there was no significant difference between the risk of respiratory distress syndrome after an elective caesarean vs. spontaneous vaginal delivery. Over the study period, gestational age at elective caesarean delivery remained stable at 39.3 ± 1.65 weeks. CONCLUSION: The incidence of respiratory distress syndrome following an elective caesarean is up to threefold higher in infants born with less than 39 weeks gestational age compared to those born by spontaneous vaginal delivery. Therefore - and whenever possible - an elective caesarean delivery should be planned after 38 completed weeks to minimise the risk of respiratory morbidity in neonates.

RESUMEN

Cervical softening and dilation are critical for the successful term delivery of a fetus, with premature changes associated with preterm birth. Traditional clinical measures like transvaginal ultrasound and Bishop scores fall short in predicting preterm births and elucidating the cervix's complex microstructural changes. Here, we introduce a magnetic resonance diffusion basis spectrum imaging (DBSI) technique for non-invasive, comprehensive imaging of cervical cellularity, collagen, and muscle fibers. This method is validated through ex vivo DBSI and histological analyses of specimens from total hysterectomies. Subsequently, retrospective in vivo DBSI analysis at 32 weeks of gestation in ten term deliveries and seven preterm deliveries with inflammation-related conditions shows distinct microstructural differences between the groups, alongside significant correlations with delivery timing. These results highlight DBSI's potential to improve understanding of premature cervical remodeling and aid in the evaluation of therapeutic interventions for at-risk pregnancies. Future studies will further assess DBSI's clinical applicability.

RESUMEN

BACKGROUND: Limited research has explored the associations of gestational age (GA) and breastfeeding practices with growth and nutrition in term infants. METHODS: This multicenter cross-sectional study recruited 7299 singleton term infants from well-child visits in Shandong, China, between March 2021 and November 2022. Data on GA, gender, ethnicity, birth weight, parental heights, gestational diabetes and hypertension, age at visit, breastfeeding practices (point-in-time data at visit for infants < 6 months and retrospective data at 6 months for infants ≥ 6 months), complementary foods introduction, infant length and weight, were collected. 7270 infants were included in the analysis after excluding outliers with Z-scores of length (LAZ), weight or weight for length (WLZ) <-4 or > 4. Linear regression models adjused for covariates explored the impact of GA and breastfeeding practices on LAZ and WLZ, while logistic regression models evaluated their effect on the likelihood of moderate and severe stunting (MSS, LAZ<-2), moderate and severe acute malnutrition (MSAM, WLZ<-2) and overweight/obesity (WLZ > 2). Sensitivity analysis was conducted on normal birth weight infants (2.5-4.0 kg). RESULTS: Infants born early-term and exclusively breastfed accounted for 31.1% and 66.4% of the sample, respectively. Early-term birth related to higher WLZ (< 6 months: ß = 0.23, 95% confidence interval (CI): 0.16, 0.29; ≥6 months: ß = 0.12, 95% CI: 0.04, 0.20) and an increased risk of overweight/obesity throughout infancy (< 6 months: OR: 1.41, 95% CI 1.08, 1.84; ≥6 months: OR: 1.35, 95% CI 1.03, 1.79). Before 6 months, early-term birth correlated with lower LAZ (ß=-0.16, 95% CI: -0.21, -0.11) and an increased risk of MSS (OR: 1.01, 95%CI 1.00, 1.02); Compared to exclusive breastfeeding, exclusive formula-feeding and mixed feeding linked to lower WLZ (ß=-0.15, 95%CI -0.30, 0.00 and ß=-0.12, 95%CI -0.19, -0.05, respectively) and increased risks of MSAM (OR: 5.57, 95%CI 1.95, 15.88 and OR: 3.19, 95%CI 1.64, 6.19, respectively). Sensitivity analyses confirmed these findings. CONCLUSIONS: The findings emphasize the health risks of early-term birth and the protective effect of exclusive breastfeeding in singleton term infants, underscoring the avoidance of nonmedically indicated delivery before 39 weeks and promoting exclusive breastfeeding before 6 months.

RESUMEN

Pregnancy results in an increase in immune cells, especially monocytes, which enhances the innate immune system. The increase of inflammatory cytokines in pregnant women's amniotic fluid, can cause uterine contraction, is linked to preterm labor. These inflammatory responses are controlled by Toll-like receptors (TLRs), which are largely expressed on neutrophils and monocytes. This study aimed to determine the role of neutrophils and monocyte subsets, as well as their expression of TLR-2 and TLR-4 in women with preterm and full-term delivery. The study involved a total of 74 women, comprising of 29 preterm labor, 25 full-term labor, and 20 non-pregnant women. The distribution of three monocyte subsets, namely (CD14++CD16-), (CD14+CD16+), and (CD14-/dim CD16++) was measured. Also, the expression of TLR2 and TLR4 in monocytes and neutrophils was analyzed using flow cytometry. Non-classical monocytes and intermediate monocytes were significantly higher in the preterm group than the control and full-term groups (p=0.041, p=0.043, and p=0.004, p= 0.049, respectively). Women in the preterm group showed significantly TLR2 expression on nonclassical monocytes compared to the control and full-term groups (p=0.002, and p=0.010, respectively). Also, preterm group expression of TLR4 was significantly higher in classical monocytes and nonclassical monocytes in comparison to the control group (p=0.019, and p≤0.0001, respectively). Besides, TLR4 expression was significantly up regulated in the preterm group compared to full-term in non-classical monocyte subset (p < 0.0001). Moreover, the expression of TLR-4 in neutrophils from the preterm group was statistically higher than expression from the full-term labor and control groups (p < .0001 for both). Such findings highlight the important role of monocyte subsets and neutrophils in activating the innate immune system and initiating strong pro-inflammatory responses that induce preterm labor. Additionally, TLR4 and TLR2 expressions on non-classical monocytes may be used as a marker to assess the probability of preterm labor.

RESUMEN

OBJECTIVE: To compare the effects of early and delayed cord clamping on the haemoglobin levels of neonates delivered at term. METHODS: This randomized controlled trial enrolled pregnant women during the second stage of labour. They were randomized into either the early cord clamping (ECC) group or the delayed cord clamping (DCC) group in the ratio of 1:1. Following delivery of the baby, the umbilical cords of participants in the ECC group were clamped within 30 s of delivery of the neonate while those of participants in the DCC group were clamped after 2 min from the delivery of the neonate. The primary outcome measure was the effect of ECC and DCC on the haemoglobin levels of neonates delivered at term. RESULTS: A total of 270 pregnant women were enrolled in the study. Their baseline sociodemographic and clinical characteristics were similar in both groups. There was no significant difference in the mean haemoglobin level between ECC and DCC groups at birth. The mean haemoglobin level of the neonates at 48 h postpartum was significantly higher in the DCC group than the ECC group. CONCLUSION: DCC at birth was associated with a significant increase in neonatal haemoglobin levels at 48 h postpartum when compared with ECC.Trial Registration: The trial was registered at Pan African Clinical Trial Registry with approval number PACTR202206735622089.

RESUMEN

OBJECTIVE: It is currently unknown whether adjunctive azithromycin prophylaxis at the time of non-elective cesarean has differential effects on neonatal outcomes in the context of prematurity. The objective of this study was to compare whether neonatal outcomes differ in term and preterm infants exposed to adjunctive azithromycin prophylaxis before non-elective cesarean delivery. STUDY DESIGN: A planned secondary analysis of a multi-center randomized controlled trial that enrolled women with singleton pregnancies ≥24 weeks gestation undergoing non-elective cesarean delivery (during labor or ≥4 h after membrane rupture). Women received standard antibiotic prophylaxis and were randomized to either adjunctive azithromycin (500 mg) or placebo. The primary composite outcome was neonatal death, suspected or confirmed neonatal sepsis, and serious neonatal morbidities (NEC, PVL, IVH, BPD). Secondary outcomes included NICU admission, neonatal readmission, culture positive infections and prevalence of resistant organisms. Odds ratios (OR) for the effect of azithromycin versus placebo were compared between gestational age strata (preterm [less than 37 weeks] versus term [37 weeks or greater]). Tests of interaction examined homogeneity of treatment effect with gestational age. RESULTS: The analysis includes 2,013 infants, 226 preterm (11.2%) and 1,787 term. Mean gestational ages were 34 and 39.5 weeks, respectively. Within term and preterm strata, maternal and delivery characteristics were similar between the azithromycin and placebo groups. There was no difference in the odds of composite neonatal outcome between those exposed to azithromycin versus placebo in preterm neonates (OR 0.82, 95% CI 0.48-1.41) and in term neonates (OR 1.06, 95% CI 0.77-1.46), with no difference between gestational age strata (p = 0.42). Analysis of secondary outcomes also revealed no differences in treatment effects within or between gestational age strata. CONCLUSION: Exposure to adjunctive azithromycin antibiotic prophylaxis for non-elective cesarean delivery does not increase neonatal morbidity or mortality in term or preterm infants.

RESUMEN

OBJECTIVE: Body temperature for a known ambient temperature is not known for infants born at term. We aimed to determine the normal range and the incidences of hypothermia and hyperthermia during the first 24 hours of life in healthy term-born infants nursed according to WHO recommendations. DESIGN: Prospective observational study. SETTING: Norwegian single centre district hospital. Infants were observed during skin-to-skin care or when dressed in cots. PARTICIPANTS: Convenience sample of 951 healthy infants born at term. METHODS: Delivery room temperature was aimed at 26-30°C and rooming-in temperature at 24°C. We measured rectal and room temperatures at 2, 4, 8, 16 and 24 hours of age. MAIN OUTCOME MEASURES: Percentile curves for rectal temperature. Proportions and risk factors for hypothermia and hyperthermia. RESULTS: The mean (SD) room temperature was 24.0°C (1.1), 23.8°C (1.0), 23.8°C (1.0)., 23.7°C (0.9) and 23.8°C (0.9). The median (2.5, 97.5 percentile) rectal temperature was 36.9°C (35.7-37.9), 36.8°C (35.9-37.5), 36.9°C (36.1-37.5), 37.0°C (36.4-37.7) and 37.1°C (36.5-37.7). Hypothermia (<36.5°C) occurred in 28% of the infants, 82% of incidents during the first 8 hours. Risk factors for hypothermia were low birth weight (OR 3.1 (95% CI, 2.0 to 4.6), per kg), male sex, being born at night and nursed in a cot versus skin to skin. Hyperthermia (>37.5°C) occurred in 12% and most commonly in large infants after 8 hours of life. Risk factors for hyperthermia were high birth weight (OR 2.2 (95% CI, 1.4 to 3.5), per kg), being awake, nursed skin to skin and being born through heavily stained amniotic fluid. CONCLUSIONS: Term-born infants were at risk of hypothermia during the first hours after birth even when nursed in an assumed adequate thermal environment and at risk of hyperthermia after 8 hours of age.

RESUMEN

INTRODUCTION: Early initiation of breastfeeding (EIBF) is still little stimulated in several hospitals in Brazil. Objective: To estimate the prevalence and factors associated with Early initiation of breastfeeding (EIBF). METHODS: Cross-sectional, quantitative study with retrospective secondary data collection in hospital records of 250 full-term newborns, regardless of the type of delivery, with no history of maternal gestational risk, seen in the last six months. Data collection period in a public maternity hospital in Greater São Paulo. Data collection was performed between November 2018 and January 2019, with approval from the hospital and the FMABC Research Ethics Committee under register n. 2,924,393. RESULTS: The prevalence of EIBF was 66%. BFH is associated with anesthesia at childbirth (p<0,001), APGAR less than or equal to 8 in the 1st and 5th minutes (p<0,001), and with c-section (p<0,001), which represented 29.2% of deliveries in the sample. Respiratory distress (38.82%), hypotonia (24.70%), followed by unfavorable maternal conditions (18.82%), were shown to be impeding factors for EIBF, although 90% of newborns received Apgar 9 /10 in the 5th minute. CONCLUSION: The prevalence of early breastfeeding is lower than recommended, but compatible with the most recent national frequency proportions.


INTRODUÇÃO: O aleitamento materno na primeira hora de vida ainda é pouco estimulado em vários hospitais do Brasil. OBJETIVO: Analisar a prevalência e os fatores associados ao aleitamento materno na primeira hora de vida (AMP) entre recém-nascidos a termo. MÉTODOS: Estudo transversal, de natureza quantitativa, com coleta de dados secundários retrospectivos em prontuários hospitalares de 250 recém-nascidos a termo, independentemente do tipo de parto, com histórico de gestacional de risco habitual, atendidos nos últimos seis meses anteriores ao período de coleta de dados, em uma maternidade pública da Grande São Paulo. Os dados foram coletados entre novembro de 2018 e janeiro de 2019, por meio de roteiro estruturado, mediante aprovação do hospital e do Comitê de Ética em Pesquisa da FMABC (Parecer n.º 2.924.393). O banco de dados e o tratamento estatístico foram realizados através do programa STATA®. Para a análise, utilizou-se proporções e teste qui-quadrado, adotando-se um nível de significância de 5% e 95% o intervalo de confiança. RESULTADOS: A prevalência de AMP foi de 66%. O AMP está associado a anestesia no parto (p<0,001), APGAR menor ou igual a 8 no 1º e 5º minutos (p<0,001) e ao parto cesárea (p<0,001), cuja proporção na amostra foi de 29,2%. Desconforto respiratório (38,82%), hipotonia (24,70%), seguido de condições maternas desfavoráveis (18,82%), mostraram-se como fatores impeditivos para o AMP, embora 90% dos recém-nascidos tenham recebido Apgar 9/10 no 5º minuto. CONCLUSÃO: A prevalência do aleitamento materno precoce é inferior ao recomendado, porém compatível com as proporções de frequência nacional mais recentes.

RESUMEN

BACKGROUND Preterm birth is one of the main causes of neonatal death worldwide. One strategy focused on preventing preterm birth is the administration of long chain polyunsaturated fatty acids (LCPUFAs) during pregnancy. Omega-3 LCPUFAs, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are essential in metabolic and physiological processes during embryonic and fetal development. This study aimed to compare DHA and EPA levels in 44 women with preterm births and 44 women with term births at a tertiary hospital in West Java Province, Indonesia, between November 2022 and March 2023. MATERIAL AND METHODS A total of 88 patients in this study consisted of 44 patients with term births (≥37 gestational weeks) and 44 patients with preterm births (<37 gestational weeks) at a tertiary hospital in West Java Province, Indonesia. This observational, cross-sectional study was conducted from November 2022 to March 2023. Using the enzyme-linked immunosorbent assay test, maternal DHA and EPA levels were investigated. IBM SPSS 24.0 was used to statistically measure outcomes. RESULTS Average maternal DHA and EPA levels in patients with preterm births were significantly lower than those in term births. Preterm labor risk was further increased by DHA levels of ≤5.70 µg/mL (OR=441.00, P=0.000) and EPA levels ≤3971.54 µg/mL (OR=441.00, P=0.000). CONCLUSIONS Since the average maternal DHA and EPA levels were significantly lower in patients with preterm births, adequate intake of omega-3 LCPUFA in early pregnancy and consistency with existing nutritional guidelines was associated with a lower risk of preterm delivery for pregnant women.

RESUMEN

Importance: The Joint Commission Unexpected Complications in Term Newborns measure characterizes newborn morbidity potentially associated with quality of labor and delivery care. Infant exclusions isolate relatively low-risk births, but unexpected newborn complications (UNCs) are not adjusted for maternal factors that may be associated with outcomes independently of hospital quality. Objective: To investigate the association between maternal characteristics and hospital UNC rates. Design, Setting, and Participants: This cohort study was conducted using linked 2016 to 2018 New York City birth and hospital discharge datasets among 254 259 neonates at low risk (singleton, ≥37 weeks, birthweight ≥2500 g, and without preexisting fetal conditions) at 39 hospitals. Logistic regression was used to calculate unadjusted hospital-specific UNC rates and replicated analyses adjusting for maternal covariates. Hospitals were categorized into UNC quintiles; changes in quintile ranking with maternal adjustment were examined. Data analyses were performed from December 2022 to July 2023. Main Outcomes and Measures: UNCs were classified according to Joint Commission International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) criteria. Maternal preadmission comorbidities, obstetric factors, social characteristics, and hospital characteristics were ascertained. Results: Among 254 259 singleton births at 37 weeks or later who were at low risk (125 245 female [49.3%] and 129 014 male [50.7%]; 71 768 births [28.2%] to Hispanic, 47 226 births [18.7%] to non-Hispanic Asian, 42 682 births [16.8%] to non-Hispanic Black, and 89 845 births [35.3%] to non-Hispanic White mothers and 2738 births [1.0%] to mothers with another race or ethnicity), 148 393 births (58.4%) were covered by Medicaid and 101 633 births (40.0%) were covered by commercial insurance. The 2016 to 2018 cumulative UNC incidence in New York City hospitals was 37.1 UNCs per 1000 births. Infants of mothers with preadmission risk factors had increased UNC risk; for example, among mothers with vs without preeclampsia, there were 104.4 and 35.8 UNCs per 1000 births, respectively. Among hospitals, unadjusted UNC rates ranged from 15.6 to 215.5 UNCs per 1000 births and adjusted UNC rates ranged from 15.6 to 194.0 UNCs per 1000 births (median [IQR] change from adjustment, 1.4 [-4.7 to 1.0] UNCs/1000 births). The median (IQR) change per 1000 births for adjusted vs unadjusted rates showed that hospitals with low (<601 deliveries/year; -2.8 [-7.0 to -1.6] UNCs) to medium (601 to <954 deliveries/year; -3.9 [-7.1 to -1.9] UNCs) delivery volume, public ownership (-3.6 [-6.2 to -2.3] UNCs), or high proportions of Medicaid-insured (eg, ≥90.72%; -3.7 [-5.3 to -1.9] UNCs), Black (eg, ≥32.83%; -5.3 [-9.1 to -2.2] UNCs), or Hispanic (eg, ≥6.25%; -3.7 [-5.3 to -1.9] UNCs) patients had significantly decreased UNC rates after adjustment, while rates increased or did not change in hospitals with the highest delivery volume, private ownership, or births to predominantly White or privately insured individuals. Among all 39 hospitals, 7 hospitals (17.9%) shifted 1 quintile comparing risk-adjusted with unadjusted quintile rankings. Conclusions and Relevance: In this study, adjustment for maternal case mix was associated with small overall changes in hospital UNC rates. These changes were associated with performance assessment for some hospitals, and these results suggest that profiling on this measure should consider the implications of small changes in rates for hospitals with higher-risk obstetric populations.

RESUMEN

BACKGROUND: Previous studies had found that the mechanical methods were as effective as pharmacological methods in achieving vaginal delivery. However, whether balloon catheter induction is suitable for women with severe cervical immaturity and whether it will increase the related risks still need to be further explored. RESEARCH AIM: To evaluate the efficacy and safety of Foley catheter balloon for labor induction at term in primiparas with different cervical scores. METHODS: A total of 688 primiparas who received cervical ripening with a Foley catheter balloon were recruited in this study. They were divided into 2 groups: Group 1 (Bishop score ≤ 3) and Group 2 (3 < Bishop score < 7). Detailed medical data before and after using of balloon were faithfully recorded. RESULTS: The cervical Bishop scores of the two groups after catheter placement were all significantly higher than those before (Group 1: 5.49 ± 1.31 VS 2.83 ± 0.39, P<0.05; Group 2: 6.09 ± 1.00 VS 4.45 ± 0.59, P<0.05). The success rate of labor induction in group 2 was higher than that in group 1 (P<0.05). The incidence of intrauterine infection in Group 1 was higher than that in Group 2 (18.3% VS 11.3%, P<0.05). CONCLUSION: The success rates of induction of labor by Foley catheter balloon were different in primiparas with different cervical conditions, the failure rate of induction of labor and the incidence of intrauterine infection were higher in primiparas with severe cervical immaturity.

RESUMEN

OBJECTIVE: To discuss several techniques of hysteroscopic surgery for complete septate uterus. CASE REPORT: A 40-year-old female with unexplained primary infertility was diagnosed with complete septate uterus with septate cervix. Hysteroscopic incision of complete septate uterus was performed by using ballooning technique. The patient conceived naturally shortly after the operation and delivered a healthy, term infant. CONCLUSION: Hysteroscopic incision of complete septate uterus is a safe and prompt way of metroplasty. With the knowledge obtained from a pre-operative MRI, it can be completed without laparoscopy and the need for hospitalization.

RESUMEN

Currently, there are no accurate means to predict spontaneous preterm birth (SPTB). Recently, we observed low expression of alpha-1 antitrypsin (AAT) in SPTB placentas. Present aim was to compare the concentrations of maternal serum AAT in pregnancies with preterm and term deliveries. Serum C-reactive protein (CRP) was used as a reference inflammatory marker. Two populations were studied. The first population comprised women who eventually gave birth spontaneously preterm (SPTB group) or term (control group). The second population included pregnant women shortly before delivery and nonpregnant women. We observed that serum AAT levels were higher in the SPTB group than in the controls, and a similar difference was observed when serum CRP was considered in multivariable analysis. However, the overlap in the AAT concentrations was considerable. No statistical significance was observed in serum AAT levels between preterm and term pregnancies at delivery. However, AAT levels were higher at delivery compared to nonpregnant controls. We did not observe a strong correlation between serum AAT and CRP in early pregnancy samples and at labor. We propose that during early pregnancy, complicated by subsequent SPTB, modest elevation of serum AAT associates with SPTB.

RESUMEN

BACKGROUND: The American Academy of Pediatrics and the Canadian Paediatric Society both advise that all newborns should undergo bilirubin screening before leaving the hospital, and this has become the standard practice in both countries. However, the US Preventive Task Force has found no strong evidence to suggest that this practice of universal screening for bilirubin reduces the occurrence of significant outcomes such as bilirubin-induced neurologic dysfunction or kernicterus. OBJECTIVES: To evaluate the effectiveness of transcutaneous screening compared to visual inspection for hyperbilirubinemia to prevent the readmission of newborns (infants greater than 35 weeks' gestation) for phototherapy. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, ClinicalTrials.gov, ICTRP, and ISRCTN in June 2023. We also searched conference proceedings, and the reference lists of included studies. SELECTION CRITERIA: We included randomized controlled trials (RCTs), quasi-randomized, cluster-randomized, or prospective cohort studies with control arm that evaluated the use of transcutaneous bilirubin (TcB) screening for hyperbilirubinemia in newborns before hospital discharge. DATA COLLECTION AND ANALYSIS: We used standard methodologic procedures expected by Cochrane. We evaluated treatment effects using a fixed-effect model with risk ratio (RR) and 95% confidence intervals (CI) for categorical data and mean, standard deviation (SD), and mean difference (MD) for continuous data. We used the GRADE approach to evaluate the certainty of evidence. MAIN RESULTS: We identified one RCT that met our inclusion criteria. The study included 1858 African newborns at 35 weeks' gestation or greater who were receiving routine care at a well-baby nursery, and were randomly recruited prior to discharge to undergo TcB screening. The study had good methodologic quality. TcB screening versus visual assessment of hyperbilirubinemia in newborns: - probably reduces readmission to the hospital for hyperbilirubinemia (RR 0.25, 95% CI 0.14 to 0.46; P < 0.0001; moderate-certainty evidence); - may have little or no effect on the rate of exchange transfusion (RR 0.20, 95% CI 0.01 to 14.16; low-certainty evidence); - probably increases the number of newborns who require phototherapy prior to discharge (RR 2.67, 95% CI 1.56 to 4.55; moderate-certainty evidence). - may have little or no effect on the rate of acute bilirubin encephalopathy (RR 0.33, 95% CI 0.01 to 8.18; low-certainty evidence). The study did not evaluate or report cost of care. AUTHORS' CONCLUSIONS: Moderate-certainty evidence suggests that TcB screening probably reduces hospital readmission for hyperbilirubinemia compared to visual inspection. Low-certainty evidence also suggests that TcB screening may have little or no effect on the rate of exchange transfusion compared to visual inspection. However, moderate-certainty evidence suggests that TcB screening probably increases the number of newborns that require phototherapy before discharge compared to visual inspection. Low-certainty evidence suggests that TcB screening may have little or no effect on the rate of acute bilirubin encephalopathy compared to visual inspection. Given that we have only identified one RCT, further studies are necessary to determine whether TcB screening can help to reduce readmission and complications related to neonatal hyperbilirubinemia. In settings with limited newborn follow-up after hospital discharge, identifying newborns at risk of severe hyperbilirubinemia before hospital discharge will be important to plan targeted follow-up of these infants.
