Purpose: Vulvodynia and vaginismus are common chronic vulvar pain disorders for which there is a paucity of literature on pregnancy outcomes of affected women. The study objective was to evaluate the associations between vulvodynia and vaginismus and obstetric outcomes. Methods: We performed a retrospective cohort study including all birth-related admissions from 1999 to October 2015 extracted from the Healthcare Cost and Utilization Project-National Inpatient Sample from the United States. Women with vulvodynia or vaginismus were identified using the appropriate ICD-9 codes. Multivariate logistic regression models, adjusted for baseline maternal characteristics, were performed to evaluate the effect of vulvodynia and vaginismus on obstetrical and neonatal outcomes. Results: A total of 879 obstetrical patients with vulvodynia or vaginismus were identified in our cohort of 13,792,544 patients admitted for delivery in US hospitals between 1999 and 2015, leading to an overall prevalence of 6 cases per 100,000 births. Between 1999 and 2015, the annual prevalence of vulvodynia or vaginismus rose from 2 to 16 cases per 100,000. Vulvodynia and vaginismus were associated with increased risks of eclampsia, chorioamnionitis, post-term pregnancy, cesarean delivery, instrumental vaginal delivery, blood transfusions, prolonged hospital stays, congenital anomalies and intrauterine growth restriction. Conclusion: Vulvodynia and vaginismus in pregnancy appears underreported in pregnancy compared to reported population rates. Prevalence of reporting seems to have increased in the last decades and is associated with increased risks of maternal and newborn morbidities. Obstetrical caregivers should be aware of the underreporting of these conditions and the associated adverse effects when counseling obstetrical patients. [ABSTRACT FROM AUTHOR]

Purpose Hidradenitis suppurativa (HS) is a debilitating chronic inflammatory skin disease with an often-unsatisfactory response to treatment. The objective was to evaluate the association between HS and pregnancy, delivery and neonatal outcomes. Methods The United States’ Healthcare Cost and Utilization Project-Nationwide Inpatient Sample database was used to conduct a retrospective cohort study among all women who delivered between 1999 and 2015. ICD-9 code 705.83 identified those with HS, with the remaining deliveries composing the comparison group. Multivariate logistic regression compared maternal and neonatal outcomes between these two groups, while adjusting for baseline maternal variables. Results The study included 13,792,544 deliveries, of which 1021 were associated with an HS diagnosis (7.4/100,000 deliveries). During the observation period, there was an upward trend in the prevalence of HS among pregnant women (<0.0001). Pregnant women with HS were more likely to be African-American, to belong to a lower income quartile, and to be insured by Medicaid. They were also more likely to smoke, to be morbidly obese, and to be hypertensive. Compared with women without HS, those with HS had a greater likelihood of developing preeclampsia (OR 1.36, 95% CI 1.08–1.71), delivering by cesarean section (OR 1.78, 95% CI 1.56–2.02), and having a baby with congenital anomalies (OR 2.00, 95% CI 1.10–3.62). Conclusions Although HS is a complex skin disorder, pregnancies complicated by HS had comparable outcomes to non-HS pregnancies, with the exception of a greater risk of preeclampsia, cesarean sections, and congenital anomalies. Health-care providers and women should be aware of these HS associated risks. [ABSTRACT FROM AUTHOR]

Purpose Pregnancy among women with end-stage renal disease (ESRD) has risen in frequency, which may be attributed to improvements in hemodialysis care. Our objective was to describe baseline characteristics and pregnancy outcomes among women with ESRD on hemodialysis. Methods Using the United States’ Healthcare Cost and Utilization Project-Nationwide Inpatient Sample, we created a cohort of women with ESRD on hemodialysis who gave birth between 2005 and 2015. We determined the proportion of adverse maternal and neonatal outcomes among this cohort. Then, we created a composite measure of vascular-mediated adverse pregnancy outcomes. Women who experienced at least one of either preeclampsia, intrauterine growth restriction, or intrauterine fetal death were categorized as having the composite measure. Then, multivariate regression models were used to estimate the associations between maternal baseline demographic and clinical characteristics and the composite measure. Results Among 8,765,973 deliveries between 2005 and 2015, 307 were to women with ESRD on hemodialysis. Over the study period, the incidence of pregnancies to women with ESRD increased from 0.47 to 5.76/100,000 births. An estimated 28% of pregnancies were complicated by preeclampsia, 8% by placental abruption, 58% delivered by cesarean, and in the postpartum, 28% required blood transfusions and 6% experienced sepsis. About 45% of babies were born preterm and 14% had IUGR. The composite measure of adverse events was not found to be associated with any baseline maternal characteristics. Conclusions The frequency of pregnant women with ESRD on hemodialysis has risen, with adverse pregnancy complications for both mother and fetus. Transfer to high-risk centers is suggested for women with ESRD. [ABSTRACT FROM AUTHOR]

Purpose: Ehlers-Danlos Syndrome (EDS) is an inherited connective tissue disorder caused by abnormal collagen synthesis. Little is known about its effects on pregnancy. The purpose of this study was to evaluate the pregnancy outcomes in women with EDS.Materials and Methods: We conducted a population-based retrospective cohort study using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from the United States. The study included women who delivered between 1999 and 2014. We measured the prevalence of EDS over time, and compared the baseline, obstetrical, and neonatal outcomes among women with EDS to the general obstetrical population without EDS. Unconditional logistic regression models were used to calculate the adjusted effect of EDS on maternal and neonatal outcomes.Results: The overall prevalence of EDS in pregnancy was 7 per 100,000 births, with the trend increasing over the 16 year study period (p < .0001). Women with EDS were more likely to be Caucasian, belong to a higher income quartile, and smoke. Pregnancies in women with EDS were associated with prematurity, 1.47 (1.18-1.82), cervical incompetence, 3.11 (1.99-4.85), antepartum hemorrhage, 1.71 (1.16-2.50), placenta previa, 2.26 (1.35-3.77) and maternal death, 9.04 (1.27-64.27). Pregnant women with EDS were more likely to be delivered by cesarean section, 1.55 (1.36-1.76), have longer postpartum stays (>7 days), 2.82 (2.08-3.85), and have a neonate with intra-uterine growth restriction, 1.81 (1.29-2.54).Conclusions: EDS in pregnancy is a high-risk condition with increased maternal morbidity and mortality, as well as newborn morbidity. Consideration should be given to prematurity preventative measures and high-risk pregnancy consultation. [ABSTRACT FROM AUTHOR]

Obsessive–compulsive disorder (OCD) is a mental disorder linked to functional impairments and adverse health outcomes. We sought to examine the association between pregnant women with OCD and obstetrical and neonatal outcomes in the USA. A retrospective population-based cohort study was conducted using data provided by pregnant women from the Nationwide Inpatient Sample, a nationally representative database of hospitalizations in the USA, from 1999 to 2015. Using diagnostic and procedure codes from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), we identified births and classified women by OCD status. Demographic and clinical characteristics were compared for women with and without OCD and multivariate logistic regressions were used to obtain odds ratios (OR) to compare obstetrical and neonatal outcomes between the two groups, adjusting for relevant demographic and clinical variables. Between 1999 and 2015, there were 3365 births to women with OCD, corresponding to an overall prevalence of 24.40 per 100,000 births. Women with OCD were more likely to be older than 25, Caucasian, of higher socioeconomic status, smokers or used drugs and alcohol, and have other comorbid psychiatric conditions. In adjusted models, OCD was associated with a higher risk of gestational hypertension, preeclampsia, premature rupture of membranes, caesarean and instrumental deliveries, venous thromboembolisms and preterm birth. Pregnancies in women with OCD are at high risk of adverse obstetrical and neonatal outcomes. A multidisciplinary approach should be used to identify high risk behaviours and ensure adequate prenatal follow-up and care be available for those with high risk pregnancies. [ABSTRACT FROM AUTHOR]

To evaluate if induction of labor (IOL) in obese women at 39 weeks of gestation decreases the risk of cesarean delivery (CD). We conducted a retrospective propensity score matched study using the Center for Disease Control's (CDC's) Period Linked Birth-Infant Death data. The study population consisted of cephalic singleton births to women with BMI greater or equal to 30.0 kg/m2 who delivered at or beyond 39 weeks between 2013 and 2017. Women with prior CD were excluded. Women who underwent IOL at 39 weeks were propensity score matched 1:5 on the basis of CD risk factors to women who did not undergo IOL at 39 weeks but may have had an IOL at a later gestational age. Conditional logistic regression compared CD rates and maternal outcomes between obese women induced at 39 weeks with those not induced at 39 weeks. Our cohort consisted of 197,343 obese women induced at 39 weeks and 986,715 obese women not induced at 39 weeks. Overall, the risk of CD among women who had an IOL at 39 weeks was lower than those without an IOL at 39 weeks, 0.59 (0.58–0.60). The decrease in CD risk was more pronounced in multiparas, 0.47 (0.46–0.49) than nulliparas, 0.81 (0.79–0.83). When stratified by BMI, the effect of IOL on lowering CD risk was similar across all obesity classes. Aside from an increased risk of instrumental deliveries, morbidities were comparable in both groups. IOL at 39 weeks among obese women appears to lower the risk of CD, without compromising maternal outcomes. [ABSTRACT FROM AUTHOR]

Purpose: Leukemia is the most common cancer among children and young adults and an increasing number of affected patients can expect a full recovery and long-term survival. The study objective was to determine the prevalence of leukemia survivors among pregnant women and to examine the maternal and fetal outcomes of this population.Materials and Methods: We conducted a retrospective population-based cohort study on all births recorded in the Health - Care Cost and Utilization Project - Nationwide Inpatient Sample between 1999 and 2014. We measured the prevalence of leukemia survivors in pregnancy and performed multivariate logistic regression to calculate adjusted odds ratios for maternal and fetal outcomes among this group compared to a nonaffected one.Results: Our cohort consisted of 14,513,587 births, of which 1,269 were to women with a history of leukemia or leukemia in remission, corresponding to a prevalence of 8.74 per 100,000 births. The prevalence rose steadily over the 16-year study period. Pregnant women who were leukemia survivors were more likely to experience gestational diabetes (OR 1.36, 95% CI 1.08-1.70), threatened preterm labor (1.50, 1.09-2.08), venous thromboembolism (4.40, 2.86-6.78), and to require blood transfusions (1.89, 1.24-2.88). Preterm deliveries (1.25, 1.02-1.54) and congenital anomalies (2.32, 1.39-3.86) among their newborns were also more common.Conclusion: The prevalence of leukemia survivors among pregnant women has been steadily rising. While the disease may no longer be active during their pregnancy, leukemia survivors appeared to have increased risks of several adverse outcomes and as such, should be monitored closely in centers with access to specialized care.

Purpose: Celiac disease (CD) is a permanent immune reaction to gluten that is likely related to genetic factors. Some studies have linked CD to adverse maternal and/or neonatal outcomes but the data has been contradictory. The purpose of this study was to evaluate the effect of CD on pregnancy outcomes.Materials and Methods: We used data from the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (NIS) of the USA to conduct a population-based retrospective cohort study of women who delivered between 1999 and 2014. Pregnancies were categorized as having CD if corresponding ICD-9 code was present. Unconditional logistic regression models were used to estimate the adjusted effect on maternal and fetal outcomes.Results: There were 14,513,587 births during the study period of which 2755 were to women with CD, for an overall prevalence of 1.9 cases/10,000 births and with rates increasing over the study period. Women with CD tended to be older, Caucasian and to have pre-existing comorbidities, especially other autoimmune diseases. Women with CD were at greater risk of hyperemesis gravidarum, 4.52 (3.68-5.57), Clostridium difficile colitis, 7.56 (3.14-18.20), and venous thromboembolic events, 2.93 (2.07-4.15), as well as, hospital stays >3 d, 2.06 (1.75-2.43). Infants of women with CD were more likely to be growth restricted, 1.80 (1.46-2.21) and have congenital malformations, 3.51 (2.68-4.58).Conclusions: CD in pregnancy is associated with increased adverse maternal and newborn complications. These pregnancies should be considered high risk and may benefit from increased surveillance. [ABSTRACT FROM AUTHOR]

Purpose: Acute leukemias (ALs) are rare but aggressive malignancies. The goal of our study was to determine the incidence, obstetrical, and newborn outcomes of ALs in pregnancy.Materials and methods: We performed a retrospective population-based cohort study on all births reported in the Health-Care Cost and Utilization Project-Nationwide Inpatient Sample between 1999 and 2014. We calculated the incidence of ALs in pregnancy and conducted multivariate logistic regression to obtain adjusted odds ratios for various maternal and newborn outcomes among this population compared to a nonaffected one.Results: We identified 291 maternal cases of ALs among 14,513,587 births, yielding an incidence of 2.01 per 100,000 births over the 15-year study period. There were approximately twice as many diagnoses of acute myeloid leukemia (AML) as compared to acute lymphoid leukemia (ALL). After adjusting for differing baseline characteristics and maternal and fetal deaths, we found that pregnant women with ALs were more likely to experience post-partum hemorrhage, to suffer from disseminated intravascular coagulation (DIC), to require transfusions, to have wound complications, and to experience venous thromboembolism (VTEs). Maternal death, preterm delivery, and intrauterine fetal death (IUFD) were more common in pregnant women with ALs.Conclusion: The incidence of ALs in pregnancy appears to be greater than what was previously believed. As it is associated with several adverse maternal and fetal outcomes, affected patients should be cared for in tertiary care institutions with access to high-risk obstetrical specialists, hematologists, and neonatologists.

Objectives: Myasthenia gravis (MG) is an autoimmune disease affecting the neuromuscular junction marked by weakness and fatiguability of skeletal muscle. MG has an unpredictable course in pregnancy. Our purpose was to evaluate the effect of MG on maternal and neonatal outcomes. Methods: Using the United States' Healthcare Cost and Utilization Project Nationwide Inpatient Sample from 2005 to 2015, we conducted a retrospective cohort study consisting of women who delivered during that period. Multivariate logistic regression models, adjusted for baseline maternal demographics and comorbidities, were used to compare maternal and neonatal outcomes among pregnancies in women with and without MG. Results: During the study period, 974 deliveries were to women diagnosed with MG. Women with MG were more likely to be older, African American, obese, have Medicare insurance and be discharged from an urban teaching hospital. Women with MG were also more likely to have chronic hypertension, pre-gestational diabetes, hypothyroidism, and chronic steroid use. Women with MG were at greater risk for acute respiratory failure (OR 13.7, 95% CI 8.9–21.2) and increased length of hospital stay (OR 2.5, 95% CI 1.9–3.3). No significant difference was observed in the risk of preterm premature rupture of membranes, caesarean section or instrumental vaginal delivery. Neonates of women with MG were more likely to be premature (OR 1.4, 95% CI 1.2–1.8). Conclusions: MG in pregnancy is a high-risk condition associated with greater risk of maternal respiratory failure and preterm birth. Management in a tertiary care center with obstetrical, neurological, anesthesia and neonatology collaboration is recommended. [ABSTRACT FROM AUTHOR]

Background: Thyroid cancer is one of the most common cancers in women of reproductive age. Our purpose was to evaluate the association between thyroid cancer and maternal and neonatal outcomes of pregnancy. Methods: We conducted a retrospective cohort study using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS) database from the US. A cohort consisting of women who delivered between 1999 and 2014 was created. Multivariate logistic regression, controlling for baseline maternal characteristics, was used to compare pregnancy complications and neonatal outcomes of pregnant women with thyroid cancer [International Classification of Diseases, ninth edition (ICD-9) code 193] diagnosed before or during pregnancy with those of the obstetric population without thyroid cancer. Results: The study included 14,513,587 pregnant women, of which 581 women had a diagnosis of thyroid cancer (4/100,000). During the observation period, there was an upward trend in the prevalence of thyroid cancer among pregnant women, though not statistically significant (P = 0.147). Women with thyroid cancer were more likely to be Caucasian, belong to a higher income quartile, have private insurance, to be discharged from an urban teaching hospital and to have pre-gestational hypertension. Women with thyroid cancer had a greater chance of delivering vaginally, requiring transfusion of blood and developing venous thromboembolism (VTE). Neonates of mothers with thyroid cancer were not found to be at increased risk for the adverse neonatal outcomes examined, specifically, congenital malformations, intrauterine growth restriction, fetal death and preterm labor. Conclusion: Pregnancies complicated by thyroid cancer have higher incidences of VTE and need for transfusions, with comparable overall newborn outcomes. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Adenomyosis is a common gynecologic disease involving the uterus with effect on pregnancy being poorly understood. This study aimed to evaluate the associations between adenomyosis and obstetrical and newborn outcomes. METHODS: Using the Healthcare Cost and Utilization Project–National Inpatient Sample from the United States, we conducted a retrospective cohort study of all birth-related admissions from 2016 to 2019. Pregnancies with adenomyosis were identified using the ICD-10 code N80.0, with the remaining pregnancies being the reference group. Multivariate logistic regression models, adjusting for baseline maternal demographics, were used to determine the effect of adenomyosis on pregnancy outcomes. In light of the diagnosis bias inherent in births by cesarean delivery, adjustment for mode of delivery was performed on all outcome analyses. RESULTS: Among the 2,943,532 women who delivered between 2016 and 2019, 1,084 had adenomyosis, for an overall prevalence of 36 cases per 100,000 births, which was stable throughout the study period. Adenomyosis in pregnancy was associated with increased frequency of placenta abruptio (odds ratio 1.67, 95% CI 1.17–2.39), preterm delivery (1.36, 1.16–1.59), preterm premature rupture of membranes (1.31, 1.07–1.61), postpartum hemorrhage (2.65, 2.14–3.27), postpartum transfusion (2.20, 1.62–2.99), disseminated intravascular coagulation (9.31, 4.15–20.92), sepsis (2.67, 1.60–4.45), congenital anomalies (1.95, 1.34–2.84), and intrauterine fetal demise (1.98, 1.02–3.84). CONCLUSION: Adenomyosis in pregnancy is associated with adverse obstetric and fetal outcomes. Pregnancies in patients with adenomyosis should be considered at higher risk and may benefit from delivering in centers capable of managing postpartum hemorrhage. [ABSTRACT FROM AUTHOR]

INTRODUCTION: The incidence of Lyme disease (LD) infections has risen in recent decades. Gestational LD has been associated with adverse pregnancy outcomes; however, the results have been contradictory. The objective of this study was to examine the effects of gestational LD on obstetrical and neonatal outcomes. METHODS: Using the Healthcare Cost and Utilization Project–National Inpatient Sample database from the United States, we conducted a retrospective cohort study of pregnant women who were admitted to hospital between 2016 and 2019. The exposed group consisted of pregnant women with gestational LD infection (ICD-10 code of A692x), whereas the comparison group consisted of pregnant women without gestational LD. Descriptive statistics and multivariate logistic regression models, adjusted for baseline maternal characteristics, were used to determine the associations between gestational LD and obstetrical and neonatal outcomes. RESULTS: Our cohort included 2,943,575 women, 226 of whom were diagnosed with LD during pregnancy. The overall incidence of gestational LD was 7.67 per 100,000 pregnancy admissions. The incidence of gestational LD was stable during the study period. Women with gestational LD were more likely to be Caucasian, older, have private health insurance, and earn higher incomes than the comparison group. Gestational LD was associated with an increased risk of placental abruption (adjusted odds ratio [aOR] 3.45, 95% CI 1.53–7.80) and preterm birth (aOR 1.58, 95% CI 1.03–2.42). CONCLUSION: Gestational LD is associated with a higher risk of placental abruption and preterm birth. Pregnancies complicated by LD may benefit from being closely monitored in tertiary care settings.
