Unexpected term NICU admissions: a marker of obstetrical care quality?

PurposePregnancies complicated by placenta accreta spectrum (PAS) are associated with severe maternal morbidities. The aim of this study is to describe the neonatal outcomes in pregnancies complicated with PAS compared with pregnancies not complicated by PAS.MethodsA retrospective cohort study conducted at a single tertiary center between 03/2011 and 01/2022, comparing women with PAS who underwent cesarean delivery (CD) to a matched control group of women without PAS who underwent CD. We evaluated the following adverse neonatal outcomes: umbilical artery pH < 7.0, umbilical artery base excess ≤ − 12, APGAR score < 7 at 5 min, neonatal intensive care unit (NICU) admission, mechanical ventilation, hypoxic ischemic encephalopathy, seizures and neonatal death. We also evaluated a composite adverse neonatal outcome, defined as the occurrence of at least one of the adverse neonatal outcomes described above. Multivariable regression analysis was used to determine which adverse neonatal outcome were independently associated with the presence of PAS.Results265 women with PAS were included in the study group and were matched to 1382 controls. In the PAS group compared with controls, the rate of composite adverse neonatal outcomes was significantly higher (33.6% vs. 18.7%, respectively, p < 0.001). In a multivariable logistic regression analysis, Apgar score < 7 at 5 min, NICU admission and composite adverse neonatal outcome were independently associated with PAS.ConclusionNeonates in PAS pregnancies had higher rates of adverse outcomes. Apgar score < 7 at 5 min, NICU admission and composite adverse neonatal outcome were independently associated with PAS.

Unexpected term NICU admissions: a marker of obstetrical care quality?

Objective:This study aimed to compare the postpartum outcomes of asymptomatic and symptomatic patients with coronavirus disease-2019 (COVID-19).Methods:This retrospective cohort study included pregnant women with COVID-19. Pregnant women were categorized into two sets as asymptomatic and symptomatic according to their clinics at the time of application. COVID-19 was diagnosed using the real-time reverse transcriptase-polymerase chain reaction on the oropharyngeal and nasopharyngeal swabs. Asymptomatic and symptomatic patients were compared in terms of maternal and perinatal outcomes.Results:Our study population consisted of 20 asymptomatic and 41 symptomatic patients with laboratory-confirmed COVID-19. The rate of primary cesarean section was more than twice in the symptomatic group (51.2%) than that of the asymptomatic group (20%) (p=0.019). Both groups are quite similar in terms of maternal [respiratory support, COVID-19-related treatment, and intensive care unit (ICU) admission], perinatal (preterm delivery, preterm premature rupture of membrane, preeclampsia, and mode of delivery), and neonatal outcomes [birth weight, Apgar scores, neonatal ICU (NICU) admission]. The rate of total cesarean section in the asymptomatic group (75%) was statistically similar to the symptomatic group (83%) (p=0.464). The NICU admission rate was found to be similar in the asymptomatic (54.2%) and symptomatic groups (50%) (p=0.858). However, NICU admissions were more frequent in the symptomatic group due to respiratory distress (p=0.032). The breastfeeding rate is higher in the asymptomatic pregnant group as expected (p=0.015). Additionally, the ferritin level was significantly lower in the asymptomatic group (p=0.006).Conclusions:The rate of primary cesarean section is quite high in symptomatic patients with COVID-19. Additionally, the total cesarean section rate was extremely high in both groups. We expected more adverse outcomes in symptomatic patients; however, we found similar maternal, perinatal, and neonatal outcomes between both groups.

To evaluate whether induction of labor (IOL), as compared with expectant management, in gestational diabetes mellitus (GDM) mothers at term (between 370/7 and 406/7), decreases caesarean section (CS) rate and the rate of adverse composite neonatal outcomes. A retrospective cohort study, of all women with GDM and a singleton gestation who delivered at term in a single, tertiary, university-affiliated medical center (2007-2014). We compared outcomes of women who underwent IOL at each week of gestation between 370/7 and 406/7weeks with women who were managed expectantly. The primary outcome was CS rate. Overall, 2472 GDM patients included in the study, of which 880 women had IOL. CS rate was not found to be significantly different between the groups at any gestational age. IOL at 37weeks was associated with adverse composite neonatal outcome (aOR 2.2, 95% CI 1.4-3.6) and NICU admission (aOR 2.5, 95% CI 1.4-4.4). At 38weeks, with NICU admission (aOR 2.0, 95% CI 1.4-2.9), and at 39weeks with fracture of the clavicle. In a sub-analysis of nulliparous women, IOL at 37weeks had higher odds of NICU admission and adverse composite neonatal outcomes, at 38weeks with CS and at 39weeks with fracture of the clavicle. IOL in GDM mothers at term does not reduce CS rate and may be associated with increased CS rate among nulliparous women at 38weeks. It is also associated with increased risk for adverse composite neonatal outcome or NICU admission when done prior to 390/7weeks.

IntroductionThis study aimed to assess whether induction of labor at 41 weeks of gestation improved perinatal outcomes in a low‐risk pregnancy compared with expectant management.Material and methodsRegistry‐based national cohort study in The Netherlands. The study population comprised 239 971 low‐risk singleton pregnancies from 2010 to 2019, with birth occurring from 41+0 to 42+0 weeks. We used propensity score matching to compare induction of labor in three 2‐day groups to expectant management, and further conducted separate analyses by parity. The main outcome measures were stillbirth, perinatal mortality, 5‐min Apgar <4 and <7, neonatal intensive care unit (NICU) admissions ≥24 h, and emergency cesarean section rate.ResultsCompared with expectant management, induction of labor at 41+0 to 41+1 weeks resulted in reduced stillbirths (adjusted odds ratio [aOR] 0.15, 95% confidence interval [CI] 0.05–0.51) in both nulliparous and multiparous women. Induction of labor increased 5‐min Apgar score <7 (aOR 1.30, 95% CI 1.09–1.55) and NICU admissions ≥24 h (aOR 2.12, 95% CI 1.53–2.92), particularly in nulliparous women, and increased the cesarean section rate (aOR 1.42, 95% CI 1.34–1.51). At 41+2–41+3 weeks, induction of labor reduced perinatal mortality (aOR 0.13, 95% CI 0.04–0.43) in both nulliparous and multiparous women. The rate of 5‐min Apgar score <7 was increased (aOR 1.26, 95% CI 1.06–1.50), reaching significance in multiparous women. The cesarean section rate increased (aOR 1.57, 95% CI 1.48–1.67) in both nulliparous and multiparous women. Induction of labor at 41+4 to 41+5 weeks reduced stillbirths (aOR 0.30, 95% CI 0.10–0.93). Induction of labor increased rates of 5‐min Apgar score <4 (aOR 1.61, 95% CI 1.01–2.56) and NICU admissions ≥24 h (aOR 1.52, 95% CI 1.08–2.13) in nulliparous women. Cesarean section rate was increased (aOR 1.47, 95% CI 1.38–1.57) in nulliparous and multiparous women.ConclusionsAt 41+2 to 41+3 weeks, induction of labor reduced perinatal mortality, and in all 2‐day groups at 41 weeks, it reduced stillbirths, compared with expectant management. Low 5‐min Apgar score (<7 and <4) and NICU admissions ≥24 h occurred more often with induction of labor, especially in nulliparous women. Induction of labor in all 2‐day groups coincided with elevated cesarean section rates in nulliparous and multiparous women. These findings pertaining to the choice of induction of labor vs expectant management should be discussed when counseling women at 41 weeks of gestation.

Can prenatal ultrasound predict adverse neonatal outcomes in SARS-CoV-2–affected pregnancies?

BackgroundThe decision to initiate pharmacotherapy is integral in the care for pregnant women with gestational diabetes mellitus (GDM). We sought to compare pregnancy outcomes between two threshold percentages of elevated glucose values prior to initiation of pharmacotherapy for GDM. We hypothesized that a lower threshold at pharmacotherapy initiation will be associated with lower rates of adverse perinatal outcomes.MethodsThis was a retrospective cohort study of women with GDM delivering in a single tertiary care center. Pregnancy outcomes were compared using bivariable and multivariable analyses between women who started pharmacotherapy (insulin or oral hypoglycemic agent) after a failed trial of dietary modifications at two different ranges of elevated capillary blood glucose (CBG) values: Group 1 when 20–39% CBG values were above goal; Group 2 when ≥40% CBG values were above goal. The primary outcome was a composite GDM-associated neonatal adverse outcome that included: macrosomia, large for gestational age (LGA), shoulder dystocia, hypoglycemia, hyperbilirubinemia requiring phototherapy, respiratory distress syndrome, stillbirth, and neonatal demise. Secondary outcomes included cesarean delivery, preterm birth (< 37 weeks), neonatal intensive care unit (NICU) admission, and small for gestational age (SGA).ResultsA total of 417 women were included in the study. In univariable analysis, the composite neonatal outcome was statistically significantly higher in Group 2 compared to Group 1 (47.9% vs. 31.4%, p = 0.001). In addition, rates of preterm birth (15.7% vs 7.4%, p = 0.011), NICU admission (11.7% vs 4.0%, p = 0.006), and LGA (21.2% vs 9.1% p = 0.001) were higher in Group 2. In contrast, higher rates of SGA were noted in Group 1 (8.0% vs. 2.9%, p = 0.019). There was no difference in cesarean section rates. These findings persisted in multivariable analysis after adjusting for confounding factors (composite neonatal outcome aOR = 0.50, 95%CI [0.31–0.78]).ConclusionsInitiation of pharmacotherapy for GDM when 20–39% of CBG values are above goal, compared to ≥40%, was associated with decreased rates of adverse neonatal outcomes attributable to GDM. This was accompanied by higher rates of SGA among women receiving pharmacotherapy at the lower threshold. Additional studies are required to identify the optimal threshold of abnormal CBG values to initiate pharmacotherapy for GDM.

Identifying underlying social risk factors for neonatal intensive care unit (NICU) admission is important for designing interventions to reduce adverse outcomes. We aimed to determine whether a patient's exposure to community-level stressors as measured by the social vulnerability index (SVI) is associated with NICU admission. Retrospective cohort study (2014-2018) of patients delivering a liveborn ≥ 22 weeks' gestation at a quaternary care center. Patient addresses were used to assign each individual a composite SVI and theme score. The primary exposure was a composite SVI score categorized into tertiles. The primary outcome was NICU admission. Secondary outcomes included NICU length of stay and neonatal morbidity composite. Multivariable logistic regression was performed to estimate the association between composite SVI and outcomes (low SVI as referent). We secondarily compared mean composite and theme SVI scores; individual components of each theme were also compared. From 2014 to 2018, 13,757 patients were included; 2,837 (21%) had a neonate with NICU admission. Patients with higher SVI were more likely to self-identify as Black race and have medical comorbidities. Living in areas with moderate or high SVI was not associated with NICU admission (moderate SVI adjusted odds ratio [aOR]: 1.13, 95% confidence interval [CI]: 0.96-1.34; high SVI aOR: 1.12, 95% CI: 0.95-1.33). Moderate SVI was associated with increased neonatal morbidity (aOR: 1.18, 95% CI: 1.001-1.38). In an analysis of SVI as a continuous variable, mean SVI scores were significantly higher in individuals who had an infant admitted to the NICU. Those requiring NICU admission lived in areas with lower per capita income and a higher number of mobile homes (p < 0.001). Patients living in areas with moderate or high SVI were not shown to have higher odds of having a neonate admitted to the NICU. Neonatal morbidity was higher in those living in areas with moderate SVI. Increased access to social services may improve neonatal outcomes. · Mean SVI scores are higher in those with a neonate admitted to the NICU.. · There was no observed association between moderate and high SVI scores and NICU admission.. · Moderate SVI is associated with an increased odds of overall neonatal morbidity.. · Greater exposure to low income may be associated with NICU admission..

Foetal male sex is associated with adverse perinatal outcomes. However, studies evaluating the impact of foetal sex on perinatal outcomes in women with gestational diabetes (GDM) are scarce. We studied whether male new-born sex is associated with neonatal outcomes, in women with GDM. This is a retrospective study based on the national Portuguese register of GDM. All women with live-born singleton pregnancies between 2012 and 2017 were eligible for study inclusion. Primary endpoints under analysis were neonatal hypoglycaemia, neonatal macrosomia, respiratory distress syndrome (RDS) and neonatal intensive care unit (NICU) admission. We excluded women with missing data on the primary endpoint. Pregnancy data and neonatal outcomes between female and male new-borns were compared. Multivariate logistic regression models were built. We studied 10,768 new-borns in mothers with GDM, 5635 (52.3%) male, 438 (4.1%) had neonatal hypoglycaemia, 406 (3.8%) were macrosomic, 671 (6.2%) had RDS, and 671 (6.2%) needed NICU admission. Male new-borns were more frequently small or large for gestational age. No differences were observed on maternal age, body mass index, glycated haemoglobin, anti-hyperglycaemic treatment, pregnancy complications or gestational age at delivery. In the multivariate regression analysis, male sex was independently associated with neonatal hypoglycaemia [OR 1.26 (IC 95%: 1.04-1.54), p = 0.02], neonatal macrosomia [1.94 (1.56-2.41), p < 0.001], NICU admission [1.29 (1.07-1.56), p = 0.009], and RDS [1.35 (1.05-1.73, p = 0.02]. Male new-borns have an independent 26% higher risk of neonatal hypoglycaemia, 29% higher risk of NICU admission, 35% higher risk of RDS, and almost twofold higher risk of macrosomia, compared to female new-borns.
