Abstract
Neonates born through meconium-stained amniotic fluid (MSAF) are at increased risk of altered cardiopulmonary transition at birth. There is a paucity of literature evaluating the transitional hemodynamics in these neonates. We aimed to evaluate transitional hemodynamics via echocardiography in neonates born through MSAF, compared to healthy neonates. The primary objective was to assess pulmonary vascular resistance using left pulmonary artery-velocity time integral (LPA-VTI). The secondary objectives were to assess other pulmonary vascular parameters and myocardial function. We enrolled 35 MSAF-born and 35 healthy neonates. Echocardiography was performed at 24 and 48 h of life by a pediatric cardiologist. Echocardiographic parameters were compared between MSAF-born and healthy neonates, and between MSAF-born neonates who developed meconium aspiration syndrome (MAS) and who did not (non-MAS). Among 35 MSAF-born neonates, 14 (40%) were non-vigorous, 18 (51%) required admission to neonatal intensive care unit, 8 (23%) developed MAS, 3 (9%) pulmonary hypertension and 1 (3%) air leak. On echocardiography, LPA-VTI (cm; mean ± SD) was significantly decreased at 24 and 48 h in MSAF-born neonates (14.38 ± 2.48; 15.55 ± 2.48), compared to healthy neonates (16.60 ± 2.14; 17.66 ± 2.71), respectively. Further, LPA-VTI was significantly reduced at 24 and 48 h among MAS (11.81 ± 3.0; 12.43 ± 2.5), compared to non-MAS neonates (15.15 ± 1.72; 16.48 ± 1.55), respectively. Other pulmonary vascular and myocardial function parameters were comparable between the two groups. Pulmonary adaptation was significantly delayed in neonates with MSAF, which was more pronounced in MAS neonates. Further studies should explore the utility of these parameters for early prediction of cardiorespiratory morbidities in this population.

J Matern Fetal Neonatal Med 2023; 36:2289348. [PMID: 38057122 DOI: 10.1080/14767058.2023.2289348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 11/25/2023] [Indexed: 12/08/2023]
Abstract
OBJECTIVE To explore whether pregnancy-induced hypertension (PIH) mediates the association between pre-pregnancy body mass index (BMI) and adverse neonatal outcomes in women undergoing assisted reproductive technology (ART) for singleton pregnancies. METHODS This cohort study collected 79437 maternal data from the National Vital Statistics System (NVSS) between 2020 and 2021. Univariable and multivariable logistic regression models were applied to estimate the association between pre-pregnancy BMI and PIH in women receiving ART as well as the associations between pre-pregnancy BMI and PIH and adverse neonatal outcomes. The mediation effect of PIH on the association between pre-pregnancy BMI and adverse neonatal outcomes was estimated according to the total effect, natural direct effect, natural indirect effect, and percentage of mediation. RESULTS There were 25769 participants had adverse neonatal outcomes at the end of the follow-up. After adjusting for confounding factors, an increased risk of PIH in women receiving ART was identified in those with pre-pregnancy BMI ≥25 kg/m2 [odds ratio (OR)=1.92, 95% confidence interval (CI):1.84-2.01]. Pre-pregnancy BMI ≥25 kg/m2 was associated with an increased risk of adverse neonatal outcomes (OR = 1.26, 95%CI:1.22-1.30). Women with PIH had an increased risk of adverse neonatal outcomes (OR = 1.79, 95%CI:1.71-1.87). The percentage mediated by PIH in the association between pre-pregnancy BMI and adverse neonatal outcomes was 21.30%. CONCLUSION PIH partially mediated the association between pre-pregnancy BMI and adverse neonatal outcomes in women receiving ART, which recommends that women control weight before receiving ART.

Abstract
Purpose This study aimed to investigate the impacts of home quarantine on pregnancy outcomes of women with intrahepatic cholestasis of pregnancy (ICP) during the COVID-19 outbreak and whether the rational use of drugs will change these impacts. Methods This multi-center study was conducted to compare the pregnancy outcomes in women with ICP between the home quarantine group and the non-home quarantine group in southwest China. Propensity score matching was performed to confirm the pregnancy outcomes of the medication group and the non-medication group in women with ICP during the epidemic period. Results A total of 3,161 women with ICP were enrolled in this study, including 816 in the home quarantine group and 2,345 in the non-home quarantine group. Women with ICP in the home quarantine group had worse pregnancy outcomes, such as a growing risk of gestational diabetes mellitus A1, fetal growth restriction, pre-eclampsia, preterm delivery, and even stillbirth. Drug therapy could alleviate some adverse pregnancy outcomes caused by home quarantine, including pre-eclampsia, preterm delivery, and meconium-stained amniotic fluid. Conclusion COVID-19 quarantine would increase the incidence of ICP and lead to adverse pregnancy outcomes in women with ICP. The rational use of drugs reduced some obstetrical complications and improved partial pregnancy outcomes. Our findings suggested that the government and hospitals should enhance their management and life guidance for women with ICP and speed up developing home quarantine guidelines.

Abstract
INTRODUCTION Our objective was to study the strength of the association between meconium-stained amniotic fluid and severe morbidity among neonates of nulliparas with prolonged pregnancies. MATERIAL AND METHODS This was a secondary analysis of the NOCETER randomized trial that took place between 2009 and 2012 in which 11 French maternity units included 1373 nulliparas at 41+0 weeks of gestation onwards with a single live fetus in cephalic presentation. This analysis excluded patients with a cesarean delivery before labor and those with bloody amniotic fluid or of unreported consistency. The principal end point was a composite criterion of severe neonatal morbidity (neonatal death, 5-minute Apgar <7, convulsions in the first 24 h, meconium aspiration syndrome, mechanical ventilation ≥24 h, or neonatal intensive care unit admission for 5 days or more). The neonatal outcomes of pregnancies with thin or thick meconium-stained amniotic fluid were compared with those with normal amniotic fluid. The association between the consistency of the amniotic fluid and neonatal morbidity was tested by univariate and then multivariate analysis adjusted for gestational age at birth, duration of labor, and country of birth. RESULTS This study included 1274 patients: 803 (63%) in the group with normal amniotic fluid, 196 (15.4%) in the thin amniotic fluid group, and 275 (21.6%) in the thick amniotic fluid group. The neonates of patients with thick amniotic fluid had higher rates of neonatal morbidity than those of patients with normal amniotic fluid (7.3% vs. 2.2%; p < 0.001; adjusted relative risk [aRR] 3.3, 95% confidence interval [CI] 1.7-6.3), but those of patients with thin amniotic fluid did not (3.1% vs. 2.2%; p = 0.50; aRR 1.0, 95% CI, 0.4-2.7). CONCLUSIONS Among nulliparas at 41+0 weeks onwards, only thick meconium-stained amniotic fluid is associated with a higher rate of severe neonatal morbidity.

Intra-Amniotic Inflammation or Infection: Suspected and Confirmed Diagnosis of "Triple I" at Term. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1110. [PMID: 37508607 PMCID: PMC10378617 DOI: 10.3390/children10071110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 06/21/2023] [Accepted: 06/23/2023] [Indexed: 07/30/2023]
Abstract
Chorioamnionitis (CA) at term of pregnancy can have an infectious and/or inflammatory origin and is associated with adverse outcomes. Triple I (intrauterine inflammation, infection, or both, TI) has been proposed to reduce the overdiagnosis of infection and neonatal overtreatment. The aim of this study is to identify clinical and histological variables that could predict adverse outcomes when TI is suspected and/or confirmed. This retrospective cohort study included 404 pregnancies (gestational age ≥ 37 weeks) that were divided into 5 all-inclusive and mutually exclusive groups. TI was defined according to the NICHD definition of 2015, and it could be confirmed (TI+) or not confirmed (TI-) via histological examination. Signs of infection/inflammation that did not conform to the definition of TI were classified as "clinical suspicion" and could be supported (CS+) or not supported (CS-) by histology. Cases of histological chorioamnionitis (HCA) without clinical manifestation represented a fifth group. Whole placental involvement (WPLI) was defined as a histological inflammation involving the maternal and fetal sides. There were 113 TI+, 30 TI-, 186 CS+, 35 CS-, and 40 isolated HCA cases. WPLI was diagnosed in 133 cases (39.2%). Composite neonatal outcome (CNO) occurred in 114 cases (28.2%) while composite maternal outcome (CMO) occurred in 192 cases (47.5%). Compared with CS+, TI+ was more predictive of CNO (p = 0.001), CMO (p < 0.001), and WPLI (p = 0.005). WPLI was related both to CNO (p < 0.001) and to CMO (p = 0.046). TI+ and WPLI showed similar sensitivity but different specificity in predicting CNO. At logistic regression, CNO was independently predicted by TI+ (OR 2.21; p = 0.001) and by WPLI (OR 2.23; p = 0.001). Compared with CS, TI is a better predictor of CNO and can be useful for the identification of newborns at risk.

Abstract
Background Meconium-stained amniotic fluid (MSAF) is considered an alarming sign of possible fetal compromise and it has recently been reported that neonatal outcome correlates with the degree of meconium thickness. Methods We retrospectively studied 400 term infants allocated in clear amniotic fluid and grade 1, 2, and 3 MSAF groups on the basis of color and thickness of AF. Multivariable logistic regression analysis was performed to evaluate the potential independent effect of delivery with MSAF of different severity on the risk of a composite adverse neonatal outcome. Results We found that delivery with grade 2 (OR 16.82, 95% Cl 2.12-33.52; p = 0.008) and 3 (OR 33.79, 95% Cl 4.24-69.33; p < 0.001) MSAF is independently correlated with the risk of adverse neonatal outcome, such as the occurrence of at least one of the following: need of resuscitation in the delivery room, blood cord pH < 7.100, occurrence of meconium aspiration syndrome (MAS), persistent pulmonary hypertension (PPH), transient tachypnea of the newborn (TTN), acute respiratory distress syndrome (ARDS), hypoxic-ischemic encephalopathy (HIE), and sepsis. Conclusions There is a positive correlation between the severity of amniotic fluid meconium staining and thickness and the outcomes of term infants. Therefore, the evaluation and grading of MSAF during labor is useful in order to plan for the presence of a neonatologist at delivery for immediate and proper neonatal care.

Abstract
BACKGROUND More than 2 million third-trimester stillbirths occur yearly, most of them in low- and middle-income countries. Data on stillbirths in these countries are rarely collected systematically. This study investigated the stillbirth rate and risk factors associated with stillbirth in four district hospitals in Pemba Island, Tanzania. METHODS A prospective cohort study was completed between the 13th of September and the 29th of November 2019. All singleton births were eligible for inclusion. Events and history during pregnancy and indicators for adherence to guidelines were analysed in a logistic regression model that identified odds ratios [OR] with a 95% confidence interval [95% CI]. RESULTS A stillbirth rate of 22 per 1000 total births in the cohort was identified; 35.5% were intrapartum stillbirths (total number of stillbirths in the cohort, n = 31). Risk factors for stillbirth were breech or cephalic malpresentation (OR 17.67, CI 7.5-41.64), decreased or no foetal movements (OR 2.6, CI 1.13-5.98), caesarean section [CS] (OR 5.19, CI 2.32-11.62), previous CS (OR 2.63, CI 1.05-6.59), preeclampsia (OR 21.54, CI 5.28-87.8), premature rupture of membranes or rupture of membranes 18 h before birth (OR 2.5, CI 1.06-5.94) and meconium stained amniotic fluid (OR 12.03, CI 5.23-27.67). Blood pressure was not routinely measured, and 25% of women with stillbirths with no registered foetal heart rate [FHR] at admission underwent CS. CONCLUSIONS The stillbirth rate in this cohort was 22 per 1000 total births and did not fulfil the Every Newborn Action Plan's goal of 12 stillbirths per 1000 total births in 2030. Awareness of risk factors associated with stillbirth, preventive interventions and improved adherence to clinical guidelines during labour, and hence improved quality of care, are needed to decrease the stillbirth rate in resource-limited settings.

Abstract
Background Grade III meconium stained amniotic fluid (MSAF) is a common obstetric disease, and has the greatest impact on poor maternal and neonatal outcomes. Question or Hypothesis or Aim There is no consensus on treatment, especially on the timing of delivery. Methods We collected the medical records of 345 women who gave birth with grade III MSAF and analyzed the difference in baseline characteristics and maternal and neonatal outcomes relative to different labor stage, observation times in the first stage of labor, and the presence or absence of abnormal fetal heart rate (FHR) or thick amniotic fluid. Findings Higher rate of cesarean section was observed when grade III MSAF was found in active labor. Intervention occurred at an observation time of 90-120 min, but there were no significant differences in maternal or neonatal outcomes shown when the observation time was greater than 3 or 4 hours. However, a higher rate of admission to the neonatal intensive care unit was demonstrated in cases with grade III MSAF with abnormal FHR either in the first or second stage of labor or in cases with thick MSAF in the second stage of labor. Discussion Higher rate of composite adverse neonatal outcomes was found when secondary MSAF (a transition from clear AF to MSAF) was diagnosed >3 h before delivery. Conclusion In the first stage of labor, an observation time of greater than 4 hours might be possible after grade III MSAF is found if the labor has progressed and is without abnormal FHR.

Abstract
OBJECTIVE The International Liaison Committee on Resuscitation (ILCOR) 2015 gave a weak recommendation based on low certainty of evidence against routine endotracheal (ET) suctioning in non-vigorous (NV) neonates born through meconium-stained amniotic fluid (MSAF) and suggested for immediate resuscitation without direct laryngoscopy. A need for ongoing surveillance post policy change has been stressed upon. This study compared the outcomes of NV MSAF neonates before and after implementation of the ILCOR 2015 recommendation. STUDY DESIGN This was a prospective cohort study of term NV MSAF neonates who underwent immediate resuscitation without ET suctioning (no ET group, July 2018 to June 2019, n = 276) compared with historical control who underwent routine ET suction (ET group, July 2015 to June 2016, n = 271). RESULTS Baseline characteristics revealed statistically significant higher proportion of male gender and small for gestational age neonates in the prospective cohort. There was no significant difference in the incidence of primary outcome of meconium aspiration syndrome (MAS) between the groups (no ET group: 27.2% vs ET group: 25.1%; p = 0.57). NV MSAF neonates with hypoxic ischemic encephalopathy (HIE) was significantly lesser in the prospective cohort (no ET group: 19.2% vs ET group: 27.3%; p = 0.03). Incidence of air leaks and need for any respiratory support significantly increased after policy change. In NV MSAF neonates with MAS, need for mechanical ventilation (MV) (no ET group: 24% vs ET group: 39.7%; p = 0.04) and mortality (no ET group: 18.7% vs ET group: 33.8%; p = 0.04) were significantly lesser. CONCLUSION Current study from a developing country indicates that immediate resuscitation and no routine ET suctioning of NV MSAF may not be associated with increased risk of MAS and may be associated with decreased risk of HIE. Increased requirement of any respiratory support and air leak post policy change needs further deliberation. Decreased risk of MV and mortality among those with MAS was observed. KEY POINTS · Not performing ET suction in NV MSAF infants is not associated with increase in the incidence of MAS.. · Initiating immediate resuscitation without ET suctioning was associated with decreased risk of HIE but increased receipt of any respiratory support and air leak.. · Large multicentric trial is required to generate robust evidence..

Abstract
OBJECTIVE To characterize pregnancies in which meconium-stained amniotic fluid (MSAF) was incidentally discovered during elective caesarean delivery (CD), and to evaluate the association with adverse neonatal outcomes. METHODS A retrospective study was performed on all patients who underwent elective CD with singleton pregnancies between March 2011 and June 2020. Data analyzed included maternal, pregnancy, and neonatal characteristics. A comparison was made between pregnancies with clear amniotic fluid, MSAF, and thick MSAF. RESULTS During the study period, 10 445 patients with singleton pregnancies underwent elective CD. Of them, 368 (3.5%) had MSAF and 31 (0.3%) had thick MSAF. Patients with MSAF gained more weight during pregnancy and suffered more from diabetes compared with patients with clear fluid. Significantly more pregnancies with MSAF had either oligohydramnios or polyhydramnios. Pregnancies in the thick-MSAF group had more intrahepatic cholestasis of pregnancy. No differences were found between the groups in the composite adverse neonatal outcome, including 5-min Apgar score, need for mechanical ventilation, and admission to the neonatal intensive care unit. CONCLUSION The incidental finding of MSAF during elective CD is not associated with increased risks of adverse neonatal outcomes.
