Exposure to Low-Level Air Pollution and Hyperglycemia Markers during Pregnancy: A Repeated Measure Analysis.

Epidemiologic evidence has emerged showing an association between exposure to air pollution and increased risks of gestational diabetes mellitus (GDM). This study examines the effect of low-level air pollution exposure on a subclinical biomarker of hyperglycemia (i.e., HbA1c) in pregnant people without diabetes before conception. We measured HbA1c in 577 samples repeatedly collected from 224 pregnant people in Rochester, NY, and estimated residential concentrations of PM2.5 and NO2 using high-resolution spatiotemporal models. We observed a U-shaped trajectory of HbA1c during pregnancy with average HbA1c levels of 5.13 (±0.52), 4.97 (±0.54), and 5.43 (±0.40)% in early-, mid-, and late pregnancy, respectively. After adjustment for the U-shaped trajectory and classic GDM risk factors, each interquartile range increase in 10 week NO2 concentration (8.0 ppb) was associated with 0.09% (95% CI: 0.02 to 0.16%) and 0.18% (95% CI: 0.08 to 0.28%) increases in HbA1c over the entire pregnancy and in late pregnancy, respectively. These associations remained robust among participants without GDM. Using separate distributed lag models, we identified a period between 8th and 14th gestational weeks as critical windows responsible for increased levels of HbA1c measured at 14th, 22nd, and 30th gestational weeks. Our results suggest that low-level air pollution contributes to hyperglycemia in medically low-risk pregnant people.

Biological changes in the pregnancy-postpartum period and subsequent cardiometabolic risk-UPSIDE MOMS: A research protocol.

Multiple physiological changes occur in pregnancy as a woman's body adapts to support the growing fetus. These pregnancy-induced changes are essential for fetal growth, but the extent to which they reverse after pregnancy remains in question. For some women, physiological changes persist after pregnancy and may increase long-term cardiometabolic disease risk. The National Institutes of Health-funded study described in this protocol addresses a scientific gap by characterizing weight and biological changes during pregnancy and an extended postpartum period in relation to cardiometabolic risk. We use a longitudinal repeated measures design to prospectively examine maternal health from early pregnancy until 3 years postpartum. The aims are: (1) identify maternal weight profiles in the pregnancy-postpartum period that predict adverse cardiometabolic risk profiles three years postpartum; (2) describe immune, endocrine, and metabolic biomarker profiles in the pregnancy-postpartum period, and determine their associations with cardiometabolic risk; and (3) determine how modifiable postpartum health behaviors (diet, physical activity, breastfeeding, sleep, stress) (a) predict weight and cardiometabolic risk in the postpartum period; and (b) moderate associations between postpartum weight retention and downstream cardiometabolic risk. The proposed sample is 250 women. This study of mothers is conducted in conjunction with the Understanding Pregnancy Signals and Infant Development study, which examines child health outcomes. Biological and behavioral data are collected in each trimester and at 6, 12, 24, and 36 months postpartum. Findings will inform targeted health strategies that promote health and reduce cardiometabolic risk in childbearing women.

Prenatal Ultrasound Measurement of Fetal Stomach Size Is Predictive of Postnatal Development of GERD in Isolated Cleft Lip and/or Palate.

OBJECTIVE: To determine whether prenatal ultrasound measurement of fetal stomach size, as a surrogate marker of fetal swallowing, is predictive of postnatal development of gastroesophageal reflux disease (GERD) in cases of isolated cleft lip and/or palate (CL/P). DESIGN: This is a retrospective case-control study. The outcome of interest is postnatal diagnosis of GERD in isolated CL/P. The exposure of interest is prenatal stomach size measurement by ultrasound. SETTING: The study population was selected from an academic, tertiary care center between 2003 and 2011. PATIENTS/PARTICIPANTS: Cases were neonates undergoing CL/P repair during the study period. Cases with other known structural or chromosomal abnormalities were excluded. Controls were contemporary, nondiabetic neonates that matched gestational age (within one week) to cases. Each case measurement was matched ∼1:2 with control measurement. INTERVENTIONS: None. MAIN OUTCOME MEASURE: The primary outcome was difference in mean prenatal ultrasound measurement of fetal stomach size between cases and controls. We hypothesized that patients with postnatal development of GERD would have smaller mean fetal stomach size. RESULTS: There were 32 cases including 19 patients with unilateral cleft lip and palate, 8 with unilateral cleft lip, and 4 with bilateral cleft lip and palate. Cases were noted to have smaller mean anterior-posterior and transverse fetal stomach measurements as compared to controls. This was statistically significant from 16 to 21 weeks, 25 to 27 weeks, and 28 to 36 weeks (P < .01 for all). CONCLUSIONS: Prenatal ultrasound measurement of fetal stomach size as a surrogate marker of fetal swallowing is predictive of postnatal development of GERD in isolated CL/P.

Evaluating sensitivity and specificity of handheld point-of-care ultrasound testing for gynecologic pathology: a pilot study for use in low resource settings.

BACKGROUND: Point-of-care ultrasound (POC-US) is a diagnostic test conducted at the site of patient care with direct interpretation by the clinician, providing immediate results. POC-US for gynecologic application is not well characterized by current literature yet has the potential to increase access in limited resource settings. We compared the diagnostics of three POC-US devices for gynecologic (GYN) pathology and then performed evaluation of sensitivity and specificity of a single best POC-US device for intended use in a low resource setting. METHODS: This is prospective, pilot descriptive study of 60 subjects. In part 1, comparison of three POC-US devices was performed. Twenty subjects underwent POC-US with three test units [GE Vscan (Vscan), Sonosite Iviz (Iviz), Philips Lumify (Lumify)] followed by diagnostic ultrasound (Dx-US) for reference imaging. Image quality and correlation for devices was scored by blinded reviewers and quantitative measurements of GYN pathology were compared. In part 2, forty subjects underwent POC-US validation with the highest scoring device (Lumify) and Dx-US for reference imaging. Concordance of POC-US operator-interpreted diagnosis with reference imaging interpretation were assessed by Cohen's unweighted kappa coefficient. Accuracy and agreement of POC-US were assessed by linear regression and Bland-Altman plot analysis. Sensitivity and specificity of POC-US for gynecologic pathologies were calculated. RESULTS: In aggregate qualitative measurements, Lumify and Iviz units performed superiorly to Vscan. There was no statistically significant difference in quantitative measurements between devices, but a trend towards lower mean error was seen for Lumify and Iviz as compared to Vscan. Lumify device had highest overall scoring and was selected for further testing. In validation comparison of Lumify to Dx-US, no statistically significant differences were found for measurements of endometrium, uterus, ovaries, adnexal pathology, or leiomyomata, (P < 0.02) with excellent agreement in operator-interpreted diagnosis (Kappa > 0.7). Sensitivity and specificity of detecting pathology was 80-100% with PPV and NPV 76-100%. CONCLUSION: Among three POC-US devices, Lumify and Iviz devices show highest potential for successful application to clinical gynecologic ultrasound. Clinician-performed POC-US has high diagnostic accuracy, sensitivity, and specificity for basic GYN anatomy and pathology. POC-US is an acceptable and feasible diagnostic tool with potential for future application in a low resource setting to increase access to ultrasound.

Neurological diseases in pregnancy.

PURPOSE OF REVIEW: To summarize recent research findings and current concepts related to care of neurologic diseases in pregnancy and the risks of pregnancy to the mother-infant dyad. Recent publications related to best practices for neurologic care, risks of pregnancy, rate of relapse during and after pregnancy, as well as medication safety in pregnancy and lactation for more commonly used neurologic medications are reviewed. RECENT FINDINGS: Data continues to grow that women with neurologic conditions can experience pregnancy with minimal risks. Additionally, as more data is being published on medication safety in pregnancy and lactation, most medical therapy is now thought to be compatible, improving symptoms and care for women with neurologic conditions who require pharmacologic treatment. However, data remains limited from clinical trials and from more objective studies. Researchers continue to clarify the impact of pregnancy on the course of chronic neurologic diseases such as multiple sclerosis, myasthenia gravis, epilepsy, migraine, and cerebral aneurysms as well as the impact of these diseases on antepartum, labor and delivery, and postpartum management and neonatal course. Acute neurological conditions with pregnancy-associated risk such as stroke, posterior reversible encephalopathy syndrome, and cerebral venous sinus thrombosis are increasingly studied to determine individuals who are most vulnerable to these serious complications. SUMMARY: Many neurological diseases coexist with pregnancy. Recent research indicates a good prognosis for both mother and neonate. Although research related to neurologic disease in pregnancy is growing, it remains an area that deserves further focus to guide evidence-based care. With advances in research on therapeutic options, some women can achieve a safe pregnancy in the setting of chronic neurological disease. VIDEO ABSTRACT: http://links.lww.com/COOG/A45.

Obese women experience multiple challenges with breastfeeding that are either unique or exacerbated by their obesity: discoveries from a longitudinal, qualitative study.

Obese women are at risk for shorter breastfeeding duration, but little is known about how obese women experience breastfeeding. The aim of this study was to understand obese women's breastfeeding experiences. We enrolled pregnant women in upstate New York, who were either obese [n = 13; body mass index (BMI) ≥30 kg/m2 ] or normal weight (n = 9; BMI 18.5-24.9 kg/m2 ) before conception and intended to breastfeed. A longitudinal, qualitative study was conducted from February 2013 through August 2014 with semi-structured interviews during pregnancy and at specific times post-partum through 3 months. Interviews were audio recorded, transcribed and analyzed using content analysis. Themes that emerged in analysis were compared between obese and normal-weight women. Differences were identified and described. Prenatally, obese women expressed less confidence about breastfeeding than normal-weight women. Post-partum, obese women and their infants had more health issues that affected breastfeeding, such as low infant blood glucose. Compared with normal-weight women, they also experienced more challenges with latching and positioning their infants. Breastfeeding required more time, props and pillows, which limited where obese women could breastfeed. Obese women also experienced more difficulty finding nursing bras and required more tangible social support than normal-weight women. In conclusion, obese women experienced more challenges than women of normal weight; some challenges were similar to those of normal-weight women but were experienced to a greater degree or a longer duration. Other challenges were unique. Obese women could benefit from targeted care prenatally and during the hospital stay as well as continued support post-partum to improve breastfeeding outcomes. © 2016 John Wiley & Sons Ltd.

Association Between Obesity During Pregnancy and the Adequacy of Prenatal Care.

OBJECTIVE: In the United States, more than a third of women are obese [body mass index (BMI) ≥ 30]. Although obese populations utilize health care at increased rates and have higher health care costs than non-obese patients, the adequacy of prenatal care in this population is not well established and assumed to be suboptimal. We therefore evaluated adequacy of prenatal care among obese women. METHODS: We utilized an electronic database including 7094 deliveries with pre-pregnancy BMI ≥ 18.5 from January 2009 through December 2011. Subjects were categorized as normal weight 18.5-24.9 kg/m2, overweight 25-29.9 kg/m2, and obese ≥30 kg/m2 (class I-II-III). Adequacy of prenatal care (PNC) was evaluated using the Kotelchuck Index (KI), corrected for gestational age at delivery. Adequate care was defined as KI "adequate" or "adequate plus," and non-adequate as "intermediate" or "inadequate." Chi square and logistic regression were used for comparisons. RESULTS: When compared to non-obese women, obese women were more likely to have adequate PNC (74.1 vs. 68.7%; OR 1.30, 95% CI 1.15-1.47). After adjusting for age, race, education, diabetes, hypertension, and practice type, obesity remained a significant predictor of adequate prenatal care (OR 1.29, 95% CI 1.14-1.46). While age and hypertension were not significant independent predictors of adequate PNC, college education, Caucasian, diabetes, and resident or MFM care had positive associations. CONCLUSION: Maternal obesity is associated with increased adequacy of prenatal care. Although some comorbidities associated with obesity increase utilization of prenatal services, this did not explain the improvement in PNC adequacy associated with obesity. SIGNIFICANCE: Overweight and obese women are at a higher risk of pregnancy complications with obesity contributing to increased morbidity and mortality of the mother. Several studies have evaluated barriers to routine health care services, with obese parturients perceiving their weight to be a barrier to obtaining appropriate care. There is limited data available assessing the adequacy of prenatal care in this population. Our study demonstrated that obesity was actually associated with an increased adequacy of prenatal care. The presence of comorbidities did not explain this improvement in prenatal care.

Do clinical practitioners seeking credentialing for nuchal translucency measurement demonstrate compliance with biosafety recommendations? Experience of the Nuchal Translucency Quality Review Program.

OBJECTIVES: The purpose of this study was to evaluate compliance with the ALARA (as low as reasonably achievable) principle by practitioners seeking credentialing for nuchal translucency (NT) measurement between 11 and 14 weeks' gestation. METHODS: Nuchal Translucency Quality Review Program credentialing requires quantitative scoring of 5 NT measurements from 5 different fetuses. Images submitted by 100 consecutive practitioners were retrospectively evaluated for the output display standard (ODS). The thermal index (TI) type (bone [TIb] or soft tissue [TIs]) and numeric value of the index were recorded. The TIb was considered the correct index for this study. Compliance with the numeric value was evaluated in several ways. Collectively, a TIb lower than 0.5 was considered optimal, lower than 0.7 compliant, and 1.0 or lower satisfactory. RESULTS: An ODS was present in at least 1 image submitted by 77 practitioners. The TIb was used exclusively by 15 (19.5%), the TIs by 37 (48.1%), and 25 used a combination of the TIb and TIs. Only 4 of 77 providers (5%) used the correct TI type (TIb) at lower than 0.5 for all submitted images, 5 of 77 (6%) at lower than 0.7, and 9 of 77 (12%) at 1.0 or lower. A TI (TIb or TIs) higher than 1.0 was used by 15 of 77 providers (19.5%). Proficiency in NT measurement and educational background (physician or sonographer) did not influence compliance with ALARA. CONCLUSIONS: Clinicians seeking credentialing in NT do not demonstrate compliance with the recommended use of the TIb in monitoring acoustic output.

Neurologic Emergencies in Pregnancy.

Neurologic emergencies in pregnancy require prompt evaluation and early, focused intervention to improve neurologic outcomes for the affected person and to avoid further injury. Neurologic events in pregnancy, although rare, present a time of extreme risk of permanent injury for the person who is pregnant. Therefore, obstetric clinicians should be well versed in the risk factors for potential neurologic events and understand the symptoms and events that should prompt evaluation for a neurologic event. In addition, they should support other specialties in aggressive and early neurologic care for the patient to improve outcomes while assessing fetal well-being and care optimization for the dyad. Obstetric clinicians can uniquely provide knowledge of changes in pregnancy physiology that can increase the risk of neurologic events, as well as change the treatment of these events. For all patients with neurologic events, "time is brain." Therefore, it is important to be aware of changes in common presenting pregnancy concerns that should prompt evaluation for other pathogeneses. Finally, pregnancy care teams should be prepared to begin the initial stabilization and management of acute neurologic emergencies, including seizure, stroke, and meningitis, while seeking aid from other medical and neurologic specialists who can support their care and interventions. Early and aggressive interventions for individuals with neurologic events during pregnancy and postpartum are critical to the overall well-being of the dyad.

Trends in Reporting of Nuchal Translucency Measurements After the Clinical Introduction of Cell-Free DNA Screening.

Nuchal translucency (NT) measurement in conjunction with serum analytes has been used for first-trimester aneuploidy screening in the United States since 2005. We sought to analyze the trends in reporting of NT measurements to the Nuchal Translucency Quality Review program in all pregnancies beginning after the clinical introduction of cell-free DNA (cfDNA) screening for fetal aneuploidy in 2011. Overall, reported NT measurements decreased 74.3% from 2012 to 2022. A similar decline was noted among individuals with pregnancies at increased risk for aneuploidy based on patient age and twin gestations. The decrease in reporting aligns temporally with the availability of cfDNA screening and the coronavirus disease 2019 (COVID-19) pandemic.

What do we know about the natural outcomes of preterm labour? A systematic review and meta-analysis of women without tocolysis in preterm labour.

BACKGROUND: Current knowledge of the natural outcomes of untreated women in preterm labour is both incomplete and outcomes vary significantly between the available studies. The aim of this study was to systematically review outcomes of preterm labour without tocolysis and determine if outcome variation could be accounted for by differences in study populations. Such data could potentially assist in the interpretation of intervention trials that do not include a no-treatment arm. METHODS: Included studies reported outcomes of women in clinically diagnosed preterm labour without tocolytic treatment between 1950 and 2011. Studies that were limited to preterm prelabour rupture of membranes, recurrent preterm labour or in which the women without tocolysis represented a potentially biased subgroup, or were not tocolysed because of contraindications were excluded. Study quality, design, and population characteristics were abstracted. Outcomes included pregnancy prolongation and the proportion of women undelivered at 48-72 h, 7 days, and term. Study characteristics associated with differing odds of preterm birth were explored through logistic regression. RESULTS: Three hundred and eighty-five citations were initially identified, of which 26 were included encompassing 1383 women. The percentage of patients who were undelivered at 48-72 hours was 62.8%, at 7 days 53.4% and 40.4% delivered at term, though the range was very wide. Characteristics associated with decreased odds of delivery were not consistent among reported outcome measures. CONCLUSIONS: Most women without tocolysis do not deliver within 7 days, although the range is very wide. The majority of this variation is unrelated to reported differences in study design or reported population characteristics.

Hermansky-Pudlak syndrome in a pregnant patient: a case report.

BACKGROUND: Hermansky-Pudlak syndrome (HPS), a rare autosomal-recessive disorder encompassing multiple organs, is characterized by oculocutaneous albinism, platelet storage pool deficiency resulting in bleeding diathesis, and ceroid lipofuscin deposition which can lead to pulmonary fibrosis, colitis, cardiomyopathy and renal failure. Pregnancy in a patient with HPS can produce multiple complications such as peripartum hemorrhage and difficulties with administration of anesthesia, either regional or general. CASE: We present the case of a patient with HPS also complicated by spontaneous triplet pregnancy. CONCLUSION: A multidisciplinary approach, including the involvement of obstetric, anesthesia, and hematology teams, is the ideal for an HPS patient with the potential for multiple complications in the peripartum period.

Association between sex steroid hormones and subsequent hyperglycemia during pregnancy.

Objective: Sex steroid hormones may play a role in insulin resistance and glucose dysregulation. However, evidence regarding associations between early-pregnancy sex steroid hormones and hyperglycemia during pregnancy is limited. The primary objective of this study was to assess the relationships between first trimester sex steroid hormones and the subsequent development of hyperglycemia during pregnancy; with secondary evaluation of sex steroid hormones levels in mid-late pregnancy, concurrent with and subsequent to diagnosis of gestational diabetes. Methods: Retrospective analysis of a prospective pregnancy cohort study was conducted. Medically low-risk participants with no known major endocrine disorders were recruited in the first trimester of pregnancy (n=319). Sex steroid hormones in each trimester, including total testosterone, free testosterone, estrone, estradiol, and estriol, were assessed using high-performance liquid chromatography and tandem mass spectrometry. Glucose levels of the 1-hour oral glucose tolerance test and gestational diabetes diagnosis were abstracted from medical records. Multivariable linear regression models were fitted to assess the associations of individual first trimester sex steroids and glucose levels. Results: In adjusted models, first trimester total testosterone (ß=5.24, 95% CI: 0.01, 10.46, p=0.05) and free testosterone (ß=5.98, 95% CI: 0.97, 10.98, p=0.02) were positively associated with subsequent glucose concentrations and gestational diabetes diagnosis (total testosterone: OR=3.63, 95% CI: 1.50, 8.78; free testosterone: OR=3.69; 95% CI: 1.56, 8.73). First trimester estrone was also positively associated with gestational diabetes (OR=3.66, 95% CI: 1.56, 8.55). In mid-late pregnancy, pregnant people with gestational diabetes had lower total testosterone levels (ß=-0.19, 95% CI: -0.36, -0.02) after adjustment for first trimester total testosterone. Conclusion: Early-pregnancy sex steroid hormones, including total testosterone, free testosterone, and estrone, were positively associated with glucose levels and gestational diabetes in mid-late pregnancy. These hormones may serve as early predictors of gestational diabetes in combination with other risk factors.

Pregnancy outcomes in type 2 diabetic patients as compared with type 1 diabetic patients and nondiabetic controls.

OBJECTIVE: To characterize the neonatal and maternal outcomes of type 2 diabetic patients as compared with type 1 diabetic patients and nondiabetic controls. STUDY DESIGN: We performed a retrospective cohort study reviewing perinatal outcomes of type 1 and type 2 diabetic patients and nondiabetic controls from July 2000 to August 2006. Analysis of variance, t testing and chi2 analysis were used to compare groups. Post hoc power analysis indicated 80% power was necessary to detect a 15% difference in composite poor neonatal outcomes. RESULTS: A total of 64 type 2 and 64 type 1 diabetic patients were compared with 256 controls. Type 1 diabetic patients had higher incidences of composite poor neonatal outcome and congenital anomalies than did type 2 diabetic and control patients. Both diabetic groups had similarly higher incidences of cesarean delivery, preeclampsia, preterm delivery, polyhydramnios and macrosomia than did controls. CONCLUSION: Type 2 diabetic patients have a decreased incidence of adverse neonatal outcomes when compared with that of type 1 diabetic patients. No difference was observed between the diabetic groups in the incidence of a majority of the adverse maternal outcomes examined, however both diabetic groups had overall worse outcomes that did nondiabetic controls.

Management of hepatic haemangioma in pregnancy.

Hepatic cavernous haemangioma is a benign tumour of vascular origin found within the liver. Often incidentally diagnosed, the management of these vascular masses is frequently determined by the size of the mass and symptoms associated with its compression of adjacent structures. Tumours >10 cm are known as giant haemangiomas and are associated with increased risks of compression symptoms, coagulopathies and haemorrhage. Known to express hormone receptors for oestrogen, intervention for these masses remains controversial in the setting of pregnancy where concerns for tumour growth and life-threatening complications are increased. Here we present the case of a woman in her 30s recently diagnosed with a giant haemangioma who is found to be pregnant, their management and a review of the literature.

The association of skin incision placement during cesarean delivery with wound complications in obese women: a systematic review and meta-analysis.

OBJECTIVE: To determine the risk of wound complications by skin incision type in obese women undergoing cesarean delivery.Data sources: Electronic databases (MEDLINE, Scopus, and Ovid) were searched from their inception through August 2018.Methods of study selection: We included all randomized controlled trials and cohort studies reporting the placement of skin incision during cesarean section in obese women, defined as those with BMI ≥30 kg/m2. Studies were included if they compared one placement of skin incision with a different one as comparison group. The primary outcome was incidence of wound complications, while secondary outcomes included wound infection, hematoma, seroma, postpartum hemorrhage, and endometritis. Demographics and outcomes for each individual study identified were reported as part of the review. Meta-analysis was performed using the random effects model of DerSimonian and Laird, to produce summary treatment effects in terms of mean difference (MD) or relative risk (RR) with 95% confidence interval (CI). Sub-group analyses (vertical versus Pfannenstiel) were also reported.Tabulation, integration and results: Seventeen studies (including 3 RCTs; 8960 participants among the 15 non-overlapping studies) were included in the systematic review. Vertical incisions were associated with a relative risk of 2.07 (95% CI1.61-2.67) for wound complications compared to transverse incisions, however significant possible confounders were present. Studies were mildly-moderately heterogeneous (I2 44.81%, 95% CI 0.00-71.85%) with varying definitions of obesity and wound complications. High transverse incisions (3 studies, 218 participants) trend toward a lower risk of wound complications compared to low transverse incisions (RR 0.338, 95% CI 0.114-1.004). CONCLUSIONS: Vertical incisions may be associated with an increased risk for wound complications compared to transverse incisions for cesarean delivery in obese women. Randomized controlled trials are needed to evaluate optimal cesarean skin incisions for these women.

Correlation between medical management and teamwork in multidisciplinary high-fidelity obstetrics simulations.

BACKGROUND: Teamwork and communication gaps are consistently cited as contributors to adverse outcomes in obstetrics. The Critical Care in Obstetrics Course provides an innovative experience by combining brief interactive didactics with the opportunity to practice and implement the knowledge gained with hands-on simulation. Most participants have never worked together, which creates a unique environment to evaluate the importance of teamwork and communication. OBJECTIVE: This study aimed to evaluate the association between teamwork and medical management in high-fidelity critical care simulations. STUDY DESIGN: The participants were separated into multidisciplinary teams and taken through simulations, including placental abruption, hypertensive emergency, eclampsia, sepsis, cardiac arrest, venous thromboembolism, diabetic ketoacidosis, and thyroid storm. Facilitators completed a validated checklist assessment for each group's performance in medical care and teamwork. Each element was rated on a scale from 1 to 5, with 1 being unacceptable and 5 being perfect. We evaluated 5 communication measures, including the use of closed-loop communication and orientation of new team members. A Spearman correlation was used to evaluate the relationship between total medical management and total teamwork scores and specific measures of team communication. Receiver operating characteristic curves were created for total teamwork score as a predictor of good or perfect medical management. RESULTS: A total of 354 multidisciplinary teams participated in 1564 high-fidelity simulations. There was a significant correlation between medical management and teamwork and communication scores for all scenarios. The strongest correlation was for the total teamwork score for all simulations (ρ=0.84). Teamwork scores were highly predictive of medical management scores with an area under the curve of at least 0.88 for all simulations, although this was not significant for diabetic ketoacidosis. CONCLUSION: The quality of teamwork and communication correlated with the quality of clinical performance in newly formed multidisciplinary teams. This demonstrates the importance of teamwork training, with a focus on key communication tools and strategies, among medical providers to optimize the management of complex and emergent obstetrical conditions.

Maternal prenatal infection and anxiety predict neurodevelopmental outcomes in middle childhood.

Prenatal maternal infection and anxiety have been linked, in separate lines of study, with child neurodevelopment. We extend and integrate these lines of study in a large prospective longitudinal cohort study of child neurodevelopment. Data are based on the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort; prenatal maternal anxiety was assessed from self-report questionnaire; prenatal infection was derived from reports of several conditions in pregnancy (n = 7,042). Child neurodevelopment at approximately 8 years of age was assessed by in-person testing, reports of social and communication problems associated with autism, and psychiatric evaluation. Covariates included psychosocial, demographic, and perinatal/obstetric risks. Prenatal infection was associated with increased likelihood of co-occurring prenatal risk, including anxiety. Regression analyses indicated that both prenatal infection and prenatal anxiety predicted child social and communication problems; the predictions were largely independent of each other. Comparable effects were also found for the prediction of symptoms of attention problems and anxiety symptoms. These results provide the first evidence for the independent effects of prenatal infection and anxiety on a broad set of neurodevelopmental and behavioral and emotional symptoms in children, suggesting the involvement of multiple mechanisms in the prenatal programming of child neurodevelopment. The results further underscore the importance of promoting prenatal physical and mental health for child health outcomes. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
