Congenital thrombotic thrombocytopenic purpura (TTP) with placental abruption despite maternal improvement: a case report.

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is a rare but serious complication in pregnancy that places the mother and fetus at high risk for morbidity and mortality. This case illustrates novel pregnancy complications associated with this rare medical condition. CASE PRESENTATION: A 31-year-old G3P0020 at 28 weeks and 1 day was admitted with severe thrombocytopenia and was ultimately diagnosed with TTP. With therapeutic plasma exchange (TPE), maternal status improved. At 28 weeks 6 days, however, non-reassuring fetal testing prompted cesarean delivery with placental abruption noted intraoperatively. Pathology examination confirmed placental abruption and also revealed multiple placental infarcts. CONCLUSION: While medical management of TTP can significantly improve the health of the mother, this case highlights the potential role of TTP in abruption and other placental pathology and thus, the need for close fetal surveillance throughout an affected pregnancy.

Labor, delivery, and anesthesia experiences of women with physical disability.

BACKGROUND: Although many women with physical disabilities report poor quality reproductive health care, little research has addressed labor, delivery, and anesthesia experiences of these women. This study was conducted to explore these experiences in women with significant mobility disabilities. METHODS: A qualitative descriptive study was conducted with 22 women from the United States who had delivered newborns within the prior 10 years. All had significant mobility disabilities. Two-hour, in-depth telephone interviews were conducted using a semistructured, open-ended interview protocol, which addressed many topics, including labor, delivery, and anesthesia experiences. We recruited most participants through social networks, interviewing women from 17 states. Conventional content analysis, facilitated by NVivo software, was used to identify major themes. RESULTS: The mean age of women was 34.8 ± 5.3 years. Most women were white, college educated, and used wheeled mobility aids. Four key themes emerged from participants' narratives of laboring and giving birth with a disability. These included women's preferences for type of delivery, clinicians and some women expected no labor pain, fears prompting active advocacy, and positive experiences. As participants discussed their experiences with anesthesia, four additional themes were identified: importance of consultation with the anesthesia team, decisions about epidural/spinal vs general anesthesia, failed epidural with repeated efforts, and fear of injury related to anesthesia. CONCLUSIONS: The responses of women in this study suggest that there is need to make intrapartum care better for women with physical disabilities and to improve their experiences with labor, birth, and obstetric anesthesia care.

Severe maternal morbidity: screening and review.

This document builds upon recommendations from peer organizations and outlines a process for identifying maternal cases that should be reviewed. Severe maternal morbidity is associated with a high rate of preventability, similar to that of maternal mortality. It also can be considered a near miss for maternal mortality because without identification and treatment, in some cases, these conditions would lead to maternal death. Identifying severe morbidity is, therefore, important for preventing such injuries that lead to mortality and for highlighting opportunities to avoid repeat injuries. The two-step screen and review process described in this document is intended to efficiently detect severe maternal morbidity in women and to ensure that each case undergoes a review to determine whether there were opportunities for improvement in care. Like cases of maternal mortality, cases of severe maternal morbidity merit quality review. In the absence of consensus on a comprehensive list of conditions that represent severe maternal morbidity, institutions and systems should either adopt an existing screening criteria or create their own list of outcomes that merit review.

Predictors of 30-day readmission following hysterectomy for benign and malignant indications at a tertiary care academic medical center.

BACKGROUND: Hospital readmissions are costly, frequent, and increasingly under public scrutiny. With increased financial constraints on the medical environment, understanding the drivers of unscheduled readmissions following gynecologic surgery will become increasingly important to value-driven care. OBJECTIVE: The current study was conducted to identify risk factors for 30-day readmission following hysterectomy for benign and malignant indications. STUDY DESIGN: A retrospective cohort study was conducted from 2008 through 2010 of all nongravid hysterectomies at a single tertiary care academic medical center. Clinical, perioperative, and physician characteristics were collected. Multivariable logistic regression models were used to identify predictors of 30-day readmission, stratified by malignant and benign indications for hysterectomy. RESULTS: Among 1649 women who underwent a hysterectomy (1009 for benign indications and 640 for malignancy), 6% were subsequently readmitted within 30 days (8.9% for malignancy vs 4.2% for benign; P < .0001). The mean time to readmission was 13 days (15 days for malignancy vs 10 days for benign; P = .004). The most common reasons for readmission were gastrointestinal (38%) and infectious (34%) etiologies, and 11.6% of readmitted patients experienced a perioperative complication. Among women undergoing hysterectomy for benign indications, a history of a laparotomy, including cesarean delivery (adjusted odds ratio [AOR], 2.12; 95% confidence interval [CI], 1.06-4.25; P = .03), as well as a perioperative complication (AOR, 2.41; 95% CI, 1.00-6.04; P = .05) were both associated with a >2-fold increased odds of readmission. Among women undergoing hysterectomy for malignancy, an American Society of Anesthesiologists Physical Status Classification of III or IV (AOR, 1.92; 95% CI, 1.05-3.50; P = .03), a longer length of initial hospitalization (3 days AOR, 7.83; 95% CI, 1.33-45.99; P = .02), and an estimated blood loss >500 mL (AOR, 3.29; 95% CI, 1.28-8.45; P = .01) were associated with a higher odds of readmission; however, women who underwent a laparoscopic hysterectomy (AOR, 0.32; 95% CI, 0.12-0.86; P = .02) and who were discharged on postoperative day 1 (AOR, 0.16; 95% CI, 0.03-0.82; P = .02) were at a decreased risk of readmission. Physician and operative characteristics were not significant predictors of readmission. CONCLUSION: This study found that malignancy, perioperative complications, and prior open abdominal surgery, including cesarean delivery, are significant risk factors for consequent 30-day readmission following index hysterectomy. It may be possible to identify patients at highest risk for readmission at the time of hysterectomy, which can assist in developing interventions to reduce such events.

Periviable birth: Interim update.

Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth. These include, but are not limited to, nonmodifiable factors (eg, fetal sex, weight, plurality), potentially modifiable antepartum and intrapartum factors (eg, location of delivery, intent to intervene by cesarean delivery or induction for delivery, administration of antenatal corticosteroids and magnesium sulfate), and postnatal management (eg, starting or withholding and continuing or withdrawing intensive care after birth). Antepartum and intrapartum management options vary depending upon the specific circumstances but may include short-term tocolytic therapy for preterm labor to allow time for administration of antenatal steroids, antibiotics to prolong latency after preterm premature rupture of membranes or for intrapartum group B streptococci prophylaxis, and delivery, including cesarean delivery, for concern regarding fetal well-being or fetal malpresentation. Whenever possible, periviable births for which maternal or neonatal intervention is planned should occur in centers that offer expertise in maternal and neonatal care and the needed infrastructure, including intensive care units, to support such services. This document describes newborn outcomes after periviable birth, provides current evidence and recommendations regarding interventions in this setting, and provides an outline for family counseling with the goal of incorporating informed patient preferences. Its intent is to provide support and guidance regarding decisions, including declining and accepting interventions and therapies, based on individual circumstances and patient values.

Chronic hypertension in pregnancy and the risk of congenital malformations: a cohort study.

OBJECTIVE: Chronic hypertension is a common medical condition in pregnancy. The purpose of the study was to examine the association between maternal chronic hypertension and the risk of congenital malformations in the offspring. STUDY DESIGN: We defined a cohort of 878,126 completed pregnancies linked to infant medical records using the Medicaid Analytic Extract. The risk of congenital malformations was compared between normotensive controls and those with treated and untreated chronic hypertension. Confounding was addressed using propensity score matching. RESULTS: After matching, compared with normotensive controls, pregnancies complicated by treated chronic hypertension were at increased risk of congenital malformations (odds ratio [OR], 1.3; 95% confidence interval [CI], 1.2-1.5), as were pregnancies with untreated chronic hypertension (OR 1.2; 95% CI, 1.1-1.3). In our analysis of organ-specific malformations, both treated and untreated chronic hypertension was associated with a significant increase in the risk of cardiac malformations (OR, 1.6; 95% CI, 1.4-1.9 and OR, 1.5; 95% CI, 1.3-1.7, respectively). These associations persisted across a range of sensitivity analyses. CONCLUSION: There is a similar increase in the risk of congenital malformations (particularly cardiac malformations) associated with treated and untreated chronic hypertension that is independent of measured confounders. Studies evaluating the teratogenic potential of antihypertensive medications must control for confounding by indication. Fetuses and neonates of mothers with chronic hypertension should be carefully evaluated for potential malformations, particularly cardiac defects.

Effects of disability on pregnancy experiences among women with impaired mobility.

OBJECTIVE: Little is known about how functional impairments might affect the pregnancies of women with mobility disability. We aimed to explore complications that arise during pregnancy that are specifically related to physical functional impairments of women with significant mobility disabilities. DESIGN: Qualitative descriptive analysis. SETTING: Telephone interviews with women from 17 USA states. SAMPLE: 22 women with significant mobility difficulties who had delivered babies within the prior 10 years; most participants were recruited through social networks. METHODS: We conducted 2-h, in-depth telephone interviews using a semi-structured, open-ended interview protocol. We used NVIVO software to sort interview transcript texts for conventional content analyses. MAIN OUTCOME MEASURES: Functional impairment-related complications during pregnancy. RESULTS: The women's mean (standard deviation) age was 34.8 (5.3) years. Most were white, well-educated, and higher income; eight women had spinal cord injuries, four cerebral palsy, and 10 had other conditions; 18 used wheeled mobility aids; and 14 had cesarean deliveries (eight elective). Impairment-related complications during pregnancy included: falls; urinary tract and bladder problems; wheelchair fit and stability problems that reduced mobility and compromised safety; significant shortness of breath, sometimes requiring respiratory support; increased spasticity; bowel management difficulties; and skin integrity problems (this was rare, but many women greatly increased skin monitoring during pregnancy to prevent pressure ulcers). CONCLUSIONS: In addition to other pregnancy-associated health risks, women with mobility disabilities appear to experience problems relating to their functional impairments. Pre-conception planning and in-depth discussions during early pregnancy could potentially assist women with mobility disabilities to anticipate and address these difficulties.

Health risk factors and mental health among US women with and without chronic physical disabilities by whether women are currently pregnant.

Growing numbers of reproductive-age US women with chronic physical disabilities (CPD) raise questions about their pregnancy experiences. Little is known about the health risks of women with versus without CPD by current pregnancy status. We analyzed cross-sectional, nationally-representative National Health Interview Survey data from 2006 to 2011, which includes 47,629 civilian, noninstitutionalized women ages 18-49. NHIS asks about specified movement difficulties, current pregnancy, and various health and health risk indicators, including tobacco use and body mass index (BMI). We used responses from eight movement difficulty and other questions to identify women with mobility difficulties caused by chronic physical health conditions. Across all women regardless of CPD, women reporting current pregnancy are significantly less likely to currently smoke tobacco and report certain mental health problems. Among currently pregnant women only, women with CPD are more likely to smoke cigarettes every day (12.2 %) versus 6.3 % for pregnant women without CPD (p ≤ 0.001). Among currently pregnant women, 17.7 % of women with CPD have BMIs in the non-overweight range, compared with 40.1 % of women without CPD (p ≤ 0.0001). Currently pregnant women with CPD are significantly more likely to report having any mental health problems, 66.6 % compared with 29.7 % among women without CPD (p ≤ 0.0001). For all women, currently pregnant women appear to have fewer health risks and mental health concerns than nonpregnant women. Among pregnant women, women with CPD have higher rates than other women of health risk factors that could affect maternal and infant outcomes.

Triggers of spontaneous preterm delivery--why today?

BACKGROUND: Our goal is to study the triggers of spontaneous preterm delivery using a case-crossover design. METHODS: In a pilot study, we enrolled 50 women with spontaneous preterm labour (PTL) and 50 with preterm premature rupture of membranes (PPROM) between 2011 and 2012. To assess non-transient risk factors, we also enrolled a control group of 158 pregnant women at their regular prenatal care visits matched to cases by gestational age and calendar time. The index time was defined as the onset of PTL/PPROM (for cases) or interview (for controls). Detailed data were collected through structured interviews regarding factors of interest during the 72 h that preceded the index time. Within case subjects, we compared the frequency of transient factors from 0 to 24 h before index time with that from 48 to 72 h before index time, and estimated matched odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Previously hypothesised chronic risk factors for spontaneous preterm delivery, including mood disorders and stressful events, were more common among cases than among controls. Within cases, skipped meals [OR 4.3, 95% CI 1.2, 15.2], disturbed sleep [OR 4.5, 95% CI 1.5, 13.3], sexual activity [OR 6.0, 95% CI 0.7, 69.8], and intake of spicy foods [OR 7.0, 95% CI 1.6, 30.8] were associated with an increased risk for PTL/PPROM within the subsequent 24 h. For physical exertion and other potential risk factors evaluated, the OR was close to the null. CONCLUSION: Skipping meals and disturbed sleep may be associated with imminent PTL/PPROM; sexual activity and spicy food may trigger PTL/PPROM in susceptible women. Larger case-crossover studies will be able to evaluate the impact of modifiable risk factors and acute predictors of PTL/PPROM, and might help guide obstetrical management.

Does professional orientation predict ethical sensitivities? Attitudes of paediatric and obstetric specialists toward fetuses, pregnant women and pregnancy termination.

BACKGROUND: To determine (1) whether fetal care paediatric (FCP) and maternal-fetal medicine (MFM) specialists harbour differing attitudes about pregnancy termination for congenital fetal conditions, their perceived responsibilities to pregnant women and fetuses, and the fetus as a patient and (2) whether self-perceived primary responsibilities to fetuses and women and views about the fetus as a patient are associated with attitudes about clinical care. METHODS: Mail survey of 434 MFM and FCP specialists (response rates 60.9% and 54.2%, respectively). RESULTS: MFMs were more likely than FCPs to disagree with these statements (all p values<0.005): (1) 'the presence of a fetal abnormality is not an appropriate reason for a couple to consider pregnancy termination' (MFM : FCP-78.4% vs 63.5%); (2) 'the effects that a child born with disabilities might have on marital and family relationships is not an appropriate reason for a couple to consider pregnancy termination' (MFM : FCP-80.5% vs 70.2%); and (3) 'the cost of healthcare for the future child is not an appropriate reason for a couple to consider pregnancy termination' (MFM : FCP-73.5% vs 55.9%). 65% MFMs versus 47% FCPs disagreed that their professional responsibility is to focus primarily on fetal well-being (p<0.01). Specialists did not differ regarding the fetus as a separate patient. Responses about self-perceived responsibility to focus on fetal well-being were associated with clinical practice attitudes. CONCLUSIONS: Independent of demographic and sociopolitical characteristics, FCPs and MFMs possess divergent ethical sensitivities regarding pregnancy termination, pregnant women and fetuses, which may influence clinical care.

Prevalence of current pregnancy among US women with and without chronic physical disabilities.

BACKGROUND: The number of US women of childbearing age who have chronic physical disabilities (CPD) is increasing. However, little is known about their reproductive experiences. Historically, women with physical disabilities have confronted stigmatized attitudes about becoming pregnant. OBJECTIVES: To explore the national prevalence of current pregnancy among women with and without CPD; examine differences in current pregnancy prevalence between these 2 groups of women. RESEARCH DESIGN: Bivariable and multivariable analyses of cross-sectional, nationally representative National Health Interview Survey data from 2006 to 2011. SUBJECTS: Forty-seven thousand six hundred twenty-nine civilian, noninstitutionalized women aged 18-49 years. MEASURES: National Health Interview Survey asks women ages 18-49 if they are currently pregnant; it also asks about various movement difficulties. We used responses from 8 movement difficulty and other questions to identify women with CPD. RESULTS: Six thousand forty-three (12.7%) sampled women report CPD. Compared with other women, women with CPD are significantly: older; more likely to be black and less likely to be Asian or Hispanic; more likely to be divorced or separated; more likely to have less than a high school education; less likely to be employed; and have much lower incomes. Across all women, 3.5% report being currently pregnant: 3.8% of women without CPD and 2.0% with CPD. Controlling for sociodemographic factors, the adjusted odds ratio (95% confidence interval) of current pregnancy is 0.83 (95% confidence interval, 0.65-1.05; P=0.12) for women with CPD compared with nondisabled women. CONCLUSIONS: Women with CPD do become pregnant, and their numbers will likely grow. Obstetrical practitioners therefore require training about the special needs of these women.

Fetal macrosomia and shoulder dystocia in women with gestational diabetes: risks amenable to treatment?

Fetal macrosomia and maternal diabetes are independent risk factors for shoulder dystocia, an obstetrical emergency that may cause permanent neonatal injury. Randomized trials of glycemic control in pregnancies complicated by gestational diabetes reveal decreased rates of macrosomia and shoulder dystocia among those treated. However, definitions of gestational diabetes vary and a specific glycemic threshold for clinically significant risk reduction remains to be delineated. This review discusses risks associated with gestational diabetes including macrosomia (birth weight above 4000-4500 g) and delivery-related morbidity, specifically, shoulder dystocia. Subsequently, we will review recent randomized trials assessing the impact of glycemic control on these delivery-related morbidities. Finally, we will examine a large observational study that found associations with delivery-related morbidity and hyperglycemia below current diabetic thresholds, observations which may suggest reexamination of current diagnosis guidelines for gestational diabetes.

Methylergonovine maleate and the risk of myocardial ischemia and infarction.

OBJECTIVE: The purpose of this study was to examine the risks of acute coronary syndrome (ACS) and acute myocardial infarction (AMI) that are associated with methylergonovine maleate (Methergine; Novartis Pharmaceuticals Corporation, Plantation, FL) use in a large database of inpatient delivery admissions in the United States. STUDY DESIGN: We conducted a retrospective cohort study using data from the Premier Perspective Database and identified 2,233,630 women who were hospitalized for delivery between 2007 and 2011 (approximately one-seventh of all US deliveries during this period). Exposure was defined by a charge code for methylergonovine during the delivery hospitalization. Study outcomes included ACS and AMI. Propensity score matching was used to address potential confounding. RESULTS: Methylergonovine was administered to 139,617 patients (6.3%). Overall, 6 patients (0.004%) who were exposed to methylergonovine and 52 patients (0.002%) who were not exposed to methylergonovine had an ACS. Four patients (0.003%) who were exposed to methylergonovine and 44 patients (0.002%) in the not-exposed group had an AMI. After propensity score matching, the relative risk for ACS that was associated with methylergonovine exposure was 1.67 (95% confidence interval [CI], 0.40-6.97), and the risk difference was 1.44 per 100,000 patients (95% CI, -2.56 to 5.45); the relative risk for AMI that was associated with methylergonovine exposure was 1.00 (95% CI, 0.20-4.95), and the risk difference was 0.00 per 100,000 patients (95% CI, -3.47 to 3.47). CONCLUSION: Despite studying a very large proportion of US deliveries, we did not find a significant increase in the risk of ACS or AMI in women who received methylergonovine compared with those who did not; estimates were increased only modestly or not at all. The upper limit of the 95% CI of our analysis suggests that treatment with methylergonovine would result in no more than 5 additional cases of ACS and 3 additional cases of AMI per 100,000 exposed patients.

Altered arterial compliance in hypertensive pregnant women is associated with preeclampsia.

BACKGROUND: Vascular alterations are present in pregnant women affected by preeclampsia. In this study, we assessed arterial compliance in women affected by hypertensive disorders of pregnancy. We hypothesized that arterial compliance is reduced in women affected by preeclampsia. METHODS: Forty-three hypertensive pregnant women undergoing evaluation for preeclampsia were studied. Clinical data about each patient and pregnancy were collected. Large (C1) and small (C2) artery compliance were assessed by radial tonometry, while the patients underwent laboratory tests to diagnose preeclampsia. At the time of delivery, gestational age and newborn data were recorded. RESULTS: Eighteen women were diagnosed with preeclampsia. C2 levels were lower among preeclamptic versus hypertensive aproteinuric women (mean ± SD, 4.5 ± 1.3 vs 5.9 ± 2.3 mL/mm Hg · 100, P = 0.013, 95% confidence interval [CI] of difference 0.32-2.55), whereas C1 levels did not differ. In the preeclampsia group, C2 levels correlated with urine total protein concentrations measured the same day (Spearman ρ = -0.49, P = 0.047, upper 95% CI -0.01) and with gestational age at first occurrence of hypertension (Spearman ρ = 0.59, P = 0.010, lower 95% CI 0.17). Among singleton gestations, C2 also correlated with newborn birth weight measured at delivery (Spearman ρ = 0.43, P = 0.009, lower 95% CI 0.11). Women who were hypertensive but aproteinuric at the time of compliance assessment, but who subsequently developed preeclampsia (n = 6), had C2 levels similar to those with an early diagnosis of preeclampsia (mean difference 0.37 mL/mm Hg · 100, 95% CI -2.42 to 1.67) and lower C2 levels than women diagnosed with gestational hypertension (P = 0.019, 95% CI 0.33-4.42 mL/mm Hg · 100). CONCLUSIONS: The noninvasive assessment of arterial elasticity may contribute toward characterization of the nature of the pathophysiology in pregnancy-induced hypertensive disorders. The vascular alterations of the small arteries, as assessed by C2, may reflect the extent of vascular alterations present with preeclampsia.

Assessing the clinical utility of toxicology testing in the peripartum period.

BACKGROUND: Toxicology testing is frequently used as a means of gathering objective data about substance use in pregnancy, but little is known about the clinical utility of testing in the peripartum setting. OBJECTIVE: This study aimed to characterize the utility of obtaining maternal-neonatal dyad toxicology testing at the time of delivery. STUDY DESIGN: We performed a retrospective chart review of all deliveries in a single healthcare system in Massachusetts between 2016 and 2020, and identified deliveries with either maternal or neonatal toxicology testing at delivery. An unexpected result was defined as a positive test for a nonprescribed substance that was not known on the basis of clinical history, self-report, or previous toxicology testing within a week of delivery, excluding results for cannabis. We evaluated the characteristics of maternal-infant dyads with unexpected positive results, unexpected positive results by rationale for testing, changes in clinical management after an unexpected positive test, and maternal outcomes in the year after delivery using descriptive statistics. RESULTS: Of the 2036 maternal-infant dyads with toxicology tests performed during the study period, there were 80 (3.9%) with an unexpected positive result. Diagnosis of substance use disorder with active use in the last 2 years was the clinical rationale for testing that yielded the greatest number of unexpected positive results (10.7% of total tests ordered for this rationale). Inadequate prenatal care (5.8%), maternal use of medication for opioid use disorder (3.8%), maternal medical indications such as hypertension or placental abruption (2.3%), history of substance use disorder in remission (1.7%), or maternal cannabis use (1.6%) yielded lower rates of unexpected results compared with a recent substance use disorder (within the last 2 years). Solely on the basis of findings from unexpected test results, 42% of dyads were referred to child protective services, 30% of dyads had no documentation of maternal counseling during delivery hospitalization, and 31% did not receive breastfeeding counseling after an unexpected test; 22.8% had monitoring for neonatal opioid withdrawal syndrome. Postpartum, 26 (32.5%) were referred to substance use disorder treatment, 31 (38.8%) attended a postpartum mental health visit, and only 26 (32.5%) attended a postpartum visit. Fifteen individuals (18.8%) were readmitted in the year after delivery, all for substance-related medical complications. CONCLUSION: Unexpected positive toxicology results at delivery were uncommon, particularly when tests were sent for frequently used clinical rationales for testing, suggesting a need to revisit guidelines surrounding appropriateness of indications for toxicology testing. The poor maternal outcomes in this cohort highlight a missed opportunity for maternal connection to counseling and treatment in the peripartum period.
