Intrapartum Outcomes

Objectives To explore the effect of introducing 24/7 resident labour ward consultant presence on neonatal and maternal outcomes in a large obstetric unit in England. Design Retrospective time sequence analysis of routinely collected data. Setting Obstetric unit of large teaching hospital in England. Participants Women and babies delivered between1 July 2011 and 30 June 2017. Births <24 weeks gestation or by planned caesarean section were excluded. Main outcome measures The primary composite outcome comprised intrapartum stillbirth, neonatal death, babies requiring therapeutic hypothermia, or admission to neonatal intensive care within three hours of birth. Secondary outcomes included markers of neonatal and maternal morbidity. Planned subgroup analyses investigated gestation (<34 weeks; 34–36 weeks; ≥37 weeks) and time of day. Results 17324 babies delivered before and 16110 after 24/7 consultant presence. The prevalence of the primary outcome increased by 0.65%, from 2.07% (359/17324) before 24/7 consultant presence to 2.72% (438/16110, P < 0.001) after 24/7 consultant presence which was consistent with an upward trend over time already well established before 24/7 consultant presence began (OR 1.09 p.a.; CI 1.04 to 1.13). Overall, there was no change in this trend associated with the transition to 24/7. However, in babies born ≥37 weeks gestation, the upward trend was reversed after implementation of 24/7 (OR 0.67 p.a.; CI 0.49 to 0.93; P = 0.017). No substantial differences were shown in other outcomes or subgroups. Conclusions Overall, resident consultant obstetrician presence 24/7 on labour ward was not associated with a change in a pre-existing trend of increasing adverse infant outcomes. However, 24/7 presence was associated with a reversal in increasing adverse outcomes for term babies.

Abstract Background In general, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during pregnancy is not considered to be an increased risk for severe maternal outcomes but has been associated with an increased risk for fetal distress. Maternal-fetal transmission of SARS-CoV-2 was initially deemed uncertain; however, recently a few cases of vertical transmission have been reported. The intrauterine mechanisms, besides direct vertical transmission, leading to the perinatal adverse outcomes are not well understood. Methods Multiple maternal, placental, and neonatal swabs were collected for the detection of SARS-CoV-2 using real-time quantitative polymerase chain reaction (RT-qPCR). Serology of immunoglobulins against SARS-CoV-2 was tested in maternal, umbilical cord, and neonatal blood. Placental examination included immunohistochemical investigation against SARS-CoV-2 antigen expression, with SARS-CoV-2 ribonucleic acid (RNA) in situ hybridization and transmission electron microscopy. Results RT-qPCRs of the oropharynx, maternal blood, vagina, placenta, and urine were all positive over a period of 6 days, while breast milk, feces, and all neonatal samples tested negative. Placental findings showed the presence of SARS-CoV-2 particles with generalized inflammation characterized by histiocytic intervillositis with diffuse perivillous fibrin depositions with damage to the syncytiotrophoblasts. Conclusions Placental infection by SARS-CoV-2 leads to fibrin depositions hampering fetal-maternal gas exchange with resulting fetal distress necessitating a premature emergency cesarean section. Postpartum, the neonate showed a fetal or pediatric inflammatory multisystem-like syndrome with coronary artery ectasia temporarily associated with SARS-CoV-2 for which admittance and care on the neonatal intensive care unit (NICU) were required, despite being negative for SARS-CoV-2. This highlights the need for awareness of adverse fetal and neonatal outcomes during the current coronavirus disease 2019 pandemic, especially considering that the majority of pregnant women appear asymptomatic.

<b><i>Objective:</i></b> The aim of the study was to determine if customized fetal growth charts developed excluding obese and underweight mothers (CC<sub>(18.5–25)</sub>) are better than customized curves (CC) at identifying pregnancies at risk of perinatal morbidity. <b><i>Material and Methods:</i></b> Data from 20,331 infants were used to construct CC and from 11,604 for CC<sub>(18.5–25)</sub>, after excluding the cases with abnormal maternal BMI. The 2 models were applied to 27,507 newborns and the perinatal outcomes were compared between large for gestational age (LGA) or small for gestational age (SGA) according to each model. Logistic regression was used to calculate the OR of outcomes by the group, with gestational age (GA) as covariable. The confidence intervals of pH were calculated by analysis of covariance. <b><i>Results:</i></b> The rate of cesarean and cephalopelvic disproportion (CPD) were higher in LGA<sub>only by CC</sub><sub><sub>(18.5−25)</sub></sub> than in LGA<sub>only by CC</sub>. In SGA<sub>only by CC</sub><sub><sub>(18.5−25)</sub></sub>, neonatal intensive care unit (NICU) and perinatal mortality rates were higher than in SGA<sub>only by CC</sub>. Adverse outcomes rate was higher in LGA<sub>only by CC</sub><sub><sub>(18.5−25)</sub></sub> than in LGA<sub>only by CC</sub> (21.6%; OR = 1.61, [1.34–193]) vs. (13.5%; OR = 0.84, [0.66–1.07]), and in SGA <sub>only by CC</sub><sub><sub>(18.5−25)</sub></sub> than in SGA<sub>only by CC</sub> (9.6%; OR = 1.62, [1.25–2.10] vs. 6.3%; OR = 1.18, [0.85–1.66]). <b><i>Conclusion:</i></b> The use of CC<sub>(18.5–25)</sub> allows a more accurate identification of LGA and SGA infants at risk of perinatal morbidity than conventional CC. This benefit increase and decrease, respectively, with GA.

Background Twin birthweight discordance is associated with adverse outcomes. Objective To determine what degree of twin birthweight discordance is associated with adverse outcomes. Study Design This is a retrospective cohort study of twins with vertex twin A delivered vaginally at 36 to 40 weeks (U.S. Vital Statistics Natality birth certificate registry data 2012–2014). The primary outcome was a composite of neonatal morbidity: 5-minute Apgar < 7, neonatal intensive care unit admission, neonatal mechanical ventilation > 6 hours, neonatal seizure, and/or neonatal transport to a higher level of care. Effect estimates were expressed as incidence rate and adjusted odds ratio (aOR) controlling for confounding using multivariate clustered analysis for between-pair effects, and multilevel random effect generalized estimating equation regressions to account for within-pair effects. We adjusted for sex discordance, breech delivery of the second twin, maternal race/ethnicity, nulliparity, age, marital status, obesity, and socioeconomic status. Results In comparison to birthweight discordance of ≤20%, aORs with 95% confidence intervals (CIs) by weight discordance of the primary outcome among 27,276 twin deliveries were as follows: 20.01 to 25% (aOR: 1.46 [95% CI: 1.29–1.65]); 25.01 to 30% (aOR: 1.96 [95% CI: 1.68–2.29]); and 30.01 to 60% (aOR: 2.97 [95% CI: 2.52–3.50]). Conclusion Twin birthweight discordance >20% was associated with increased odds of adverse neonatal outcome.

Regular physical activity during pregnancy improves or maintains physical fitness, helps with weight management, reduces the risk of gestational diabetes, and enhances patient’s psychological well-being. We studied the possibility to use maternal exercise to test placental reserves in diabetic mothers. We used a motorized treadmill in a moderate exercise regimen (15-minute fast walk at a speed of 3 mph with an incline of 15-25 degrees). Fetal monitoring was provided by using standard Phillips equipment (Avalon CTS and FM40). Adverse fetal outcomes were considered if one or more of the following were present: Category III Fetal Heart Rate (FHR) tracing, 5-minute Apgar score of less than 7, admission to the neonatal intensive care nursery, fetal growth restriction, and fetal and early neonatal death. A total of 819 fetal assessments were performed: 160 patients had gestational diabetes, 80 had pregestational diabetes. The most common complication in fetuses with positive prenatal test results was abnormal FHR in labor (36%) followed by low Apgar score (21%) and need for NICU admission (19%). Most of the adverse outcomes had good correlation with positive results of the exercise test. In conclusion, it appears that maternal exercise causes changes in FHR, which may be used to assess placental and fetal reserves.

OBJECTIVEAdult ventilator-associated event (VAE) definitions include ventilator-associated conditions (VAC) and subcategories for infection-related ventilator-associated complications (IVAC) and possible ventilator-associated pneumonia (PVAP). We explored these definitions for children.DESIGNRetrospective cohortSETTINGPediatric, cardiac, or neonatal intensive care units (ICUs) in 6 US hospitalsPATIENTSPatients ≤18 years old ventilated for ≥1 dayMETHODSWe identified patients with pediatric VAC based on previously proposed criteria. We applied adult temperature, white blood cell count, antibiotic, and culture criteria for IVAC and PVAP to these patients. We matched pediatric VAC patients with controls and evaluated associations with adverse outcomes using Cox proportional hazards models.RESULTSIn total, 233 pediatric VACs (12,167 ventilation episodes) were identified. In the cardiac ICU (CICU), 62.5% of VACs met adult IVAC criteria; in the pediatric ICU (PICU), 54.2% of VACs met adult IVAC criteria; and in the neonatal ICU (NICU), 20.2% of VACs met adult IVAC criteria. Most patients had abnormal white blood cell counts and temperatures; we therefore recommend simplifying surveillance by focusing on “pediatric VAC with antimicrobial use” (pediatric AVAC). Pediatric AVAC with a positive respiratory diagnostic test (“pediatric PVAP”) occurred in 8.9% of VACs in the CICU, 13.3% of VACs in the PICU, and 4.3% of VACs in the NICU. Hospital mortality was increased, and hospital and ICU length of stay and duration of ventilation were prolonged among all pediatric VAE subsets compared with controls.CONCLUSIONSWe propose pediatric AVAC for surveillance related to antimicrobial use, with pediatric PVAP as a subset of AVAC. Studies on generalizability and responsiveness of these metrics to quality improvement initiatives are needed, as are studies to determine whether lower pediatric VAE rates are associated with improvements in other outcomes.Infect Control Hosp Epidemiol 2017;38:327–333

The Impact

Objective. The study of biological rhythms and the influence of environmental factors in the timing and synchronization of different rhythmic events have important implications for neonatal health. Preterm infants in the neonatal intensive care unit (NICU) are deprived of the patterned influences of maternal sleep, temperature, heart rate, and hormonal cycles. The impact of the NICU and nursing interventions on the development of the circadian system was studied in 17 stable preterm infants in the Intermediate Intensive Care Nursery at Stanford University for three consecutive days at about 35 weeks postconceptional age. Outcome measurements. Rectal temperature, abdominal skin temperature, heart rate, and activity were simultaneously recorded at 2-minute intervals during each 3-day study by a small microcomputer (Vitalog). Results. Very low amplitude circadian rhythms were found for rectal and skin temperatures (maximum range 36.8 to 37.0°C); population mean values for heart rate (158 bpm) and activity (3.5 counts per 2-min bin) did not differ significantly as a function of time of day. Rectal temperature, averaged in 6-hour bins over the 24-hour day as a function of both postconceptional age and postnatal age, was significantly higher during the first part of the circadian cycle. In all infants, rhythmicity in each variable was dominated by ultradian periodicities that were coincident with feedings and related interventions; moreover, several physiological variables charted during feeding differed significantly from values obtained during periods in which caregiving interventions did not occur. Conclusion. Quantitative data on the preterm infant circadian system may facilitate evaluation of factors that improve therapeutic responses, recovery, and outcome of neonatal intensive care patients.

Primary Composite Outcome

Abstract Background Annually in the US alone, Clostridioides difficile infection (CDI) afflicts nearly 500,000 patients causing 29,000 deaths. Since early and aggressive interventions could save lives but are not optimally deployed in all patients, numerous studies have published predictive models for adverse outcomes. These models are usually developed at a single institution, and largely are not externally validated. This aim of this study was to validate the predictability for severe CDI with previously published risk scores in a multicenter cohort of patients with CDI. Methods We conducted a retrospective study on four separate inpatient cohorts with CDI from three distinct sites: the Universities of Michigan (2010–2012 and 2016), Chicago (2012), and Wisconsin (2012). The primary composite outcome was admission to an intensive care unit, colectomy, and/or death attributed to CDI within 30 days of positive test. Structured query and manual chart review abstracted data from the medical record at each site. Published CDI severity scores were assessed and compared with each other and the IDSA guideline definition of severe CDI. Sensitivity, specificity, area under the receiver operator characteristic curve (AuROC), precision-recall curves, and net reclassification index (NRI) were calculated to compare models. Results We included 3,775 patients from the four cohorts (Table 1) and evaluated eight severity scores (Table 2). The IDSA (baseline comparator) model showed poor performance across cohorts(Table 3). Of the binary classification models, including those that were most predictive of the primary composite outcome, Jardin, performed poorly with minimal to no NRI improvement compared with IDSA. The continuous score models, Toro and ATLAS, performed better, but the AuROC varied by site by up to 17% (Table 3). The Gujja model varied the most: from most predictive in the University of Michigan 2010–2012 cohort to having no predictive value in the 2016 cohort (Table 3). Conclusion No published CDI severity score showed stable, acceptable predictive ability across multiple cohorts/institutions. To maximize performance and clinical utility, future efforts should focus on a multicenter-derived and validated scoring system, and/or incorporate novel biomarkers.

A didelphys uterus also known as a “double uterus” is one of the least common Mullerian duct anomalies. Uterine didelphys is a congenital malformation that result from complete failure of fusion of the ipsilateral Mullerian duct during embryonic development. Ideally, diagnosis should be made before pregnancy and labour to prevent adverse outcomes. Here reporting a case who was a 19 years old, 4thgravida, Para: 0+3 (Spontaneous abortion) referred to Bangabandhu Memorial Hospital (BBMH) USTC, Chittagong at 35 weeks of pregnancy with severe abdominal pain by local physician from Raozan, Chittagong. On vaginal examination a longitudinal vaginal septum and two vagina were found. Uterine Didelphys was confirmed during emergency caesarean section and delivered 1.5 kg male baby with APGAR score 7/10 and was referred to Neonatal Intensive Care Unit (NICU). Post operative recovery of the mother was uneventful. The baby was also discharged at the age of seven days with establishment of breast feeding. To avoid delayed diagnosis and associated adverse outcome clinicians should have high index of suspicion of uterine anomaly when assessing cases of dysfunctional labour.

Objective Evaluate the association between spontaneous active labor duration utilizing contemporary labor curves and risk of adverse outcomes. Materials and Methods This is a retrospective cohort study from January 2012 to January 2015. Subjects were nulliparous, 18 to 44 years, with a cephalic, singleton ≥37 weeks in spontaneous labor. Subjects were placed into three subgroups, defined by active labor duration from 6 to 10 cm as less than the median, the median-95th, and >95th percentile based on contemporary labor curves published by Zhang et al. We evaluated the association between subgroups and cesarean delivery, chorioamnionitis, estimated blood loss, Apgar score < 7 at 5 minutes, and neonatal intensive care unit admission using logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI). Results Six-hundred forty two women met the inclusion criteria. Compared with women whose active labor was less than the median, the risk of cesarean was higher in the median-95th percentile ([adjusted OR, aOR] 3.1, 95% CI 1.8–5.5) and the >95th percentile ([aOR] 6.8, 95% CI 3.9–11.7) subgroups. There was an increased odds of chorioamnionitis in the median-95th percentile subgroup ([aOR] 2.5, 95% CI 1.1–5.9). Conclusion Chorioamnionitis and cesarean delivery increased significantly as labor duration exceeded the median. This study provides a better understanding regarding the potential risk of cesarean and chorioamnionitis using contemporary labor curves.
