RESUMEN
BACKGROUND: Establishing local trimester-specific reference intervals for gestational TSH and FT4 is often not feasible, necessitating alternative strategies. We aimed to systematically quantify the diagnostic performance of standardized modifications of center-specific non-pregnancy reference intervals as compared to trimester-specific reference intervals. METHODS: We included prospective cohorts participating in the Consortium on Thyroid and Pregnancy. After relevant exclusions, reference intervals were calculated per cohort in thyroperoxidase antibody-negative women. Modifications to the non-pregnancy reference intervals included an absolute modification (per 0.1 mU/L TSH or 1 pmol/L FT4), relative modification (in steps of 5%) and fixed limits (upper TSH limit between 3.0 to 4.5 mU/L and lower FT4 limit 5-15 pmol/L). We compared (sub)clinical hypothyroidism prevalence, sensitivity and positive predictive value (PPV) of aforementioned methodologies with population-based trimester-specific reference intervals. RESULTS: The final study population comprised 52,496 participants in 18 cohorts. Optimal modifications of standard reference intervals to diagnose gestational overt hypothyroidism were -5% for the upper limit of TSH and +5% for the lower limit of FT4 (sensitivity 0.70, confidence interval [CI] 0.47-0.86; PPV 0.64, CI 0.54-0.74). For subclinical hypothyroidism, these were -20% for the upper limit of TSH and -15% for the lower limit of FT4 (sensitivity 0.91, CI 0.67-0.98; PPV 0.71, CI 0.58-0.80). Absolute and fixed modifications yielded similar results. Confidence intervals were wide, limiting generalizability. CONCLUSION: We could not identify modifications of non-pregnancy TSH and FT4 reference intervals that would enable centers to adequately approximate trimester-specific reference intervals. Future efforts should be turned towards studying the meaningfulness of trimester-specific reference intervals and risk-based decision limits.
RESUMEN
Objective: Routine health care visits offer the opportunity to screen older adults for symptoms of Alzheimer's disease (AD). Many women see their gynecologist as their primary health care provider. Given this unique relationship, the Women's Preventive Services Initiative and the American College of Obstetrics and Gynecology advocate for integrated care of women at all ages. It is well-established that women are at increased risk for AD, and memory screening of older women should be paramount in this effort. Research is needed to determine the feasibility and value of memory screening among older women at the well-woman visit. Materials and Methods: Women aged 60 and above completed a 5-item subjective memory screener at their well-woman visit at the Columbia University Integrated Women's Health Program. Women who endorsed any item were considered to have a positive screen and were given the option to pursue clinical evaluation. Rates of positive screens, item endorsement, and referral preferences were examined. Results: Of the 530 women approached, 521 agreed to complete the screener. Of those, 17.5% (n = 91) were classified as positive. The most frequently endorsed item was difficulty with memory or thinking compared with others the same age. Among women with positive screens, 57.5% were interested in pursuing clinical referrals to a memory specialist. Conclusion: Results support the feasibility and potential value of including subjective memory screening as part of a comprehensive well-woman program. Early identification of memory loss will enable investigation into the cause of memory symptoms and longitudinal monitoring of cognitive change.
RESUMEN
BACKGROUND: A major goal of contemporary obstetrical practice is to optimize fetal growth and development throughout pregnancy. To date, fetal growth during prenatal care is assessed by performing ultrasonographic measurement of 2-dimensional fetal biometry to calculate an estimated fetal weight. Our group previously established 2-dimensional fetal growth standards using sonographic data from a large cohort with multiple sonograms. A separate objective of that investigation involved the collection of fetal volumes from the same cohort. OBJECTIVE: The Fetal 3D Study was designed to establish standards for fetal soft tissue and organ volume measurements by 3-dimensional ultrasonography and compare growth trajectories with conventional 2-dimensional measures where applicable. STUDY DESIGN: The National Institute of Child Health and Human Development Fetal 3D Study included research-quality images of singletons collected in a prospective, racially and ethnically diverse, low-risk cohort of pregnant individuals at 12 U.S. sites, with up to 5 scans per fetus (N=1730 fetuses). Abdominal subcutaneous tissue thickness was measured from 2-dimensional images and fetal limb soft tissue parameters extracted from 3-dimensional multiplanar views. Cerebellar, lung, liver, and kidney volumes were measured using virtual organ computer aided analysis. Fractional arm and thigh total volumes, and fractional lean limb volumes were measured, with fractional limb fat volume calculated by subtracting lean from total. For each measure, weighted curves (fifth, 50th, 95th percentiles) were derived from 15 to 41 weeks' using linear mixed models for repeated measures with cubic splines. RESULTS: Subcutaneous thickness of the abdomen, arm, and thigh increased linearly, with slight acceleration around 27 to 29 weeks. Fractional volumes of the arm, thigh, and lean limb volumes increased along a quadratic curvature, with acceleration around 29 to 30 weeks. In contrast, growth patterns for 2-dimensional humerus and femur lengths demonstrated a logarithmic shape, with fastest growth in the second trimester. The mid-arm area curve was similar in shape to fractional arm volume, with an acceleration around 30 weeks, whereas the curve for the lean arm area was more gradual. The abdominal area curve was similar to the mid-arm area curve with an acceleration around 29 weeks. The mid-thigh and lean area curves differed from the arm areas by exhibiting a deceleration at 39 weeks. The growth curves for the mid-arm and thigh circumferences were more linear. Cerebellar 2-dimensional diameter increased linearly, whereas cerebellar 3-dimensional volume growth gradually accelerated until 32 weeks followed by a more linear growth. Lung, kidney, and liver volumes all demonstrated gradual early growth followed by a linear acceleration beginning at 25 weeks for lungs, 26 to 27 weeks for kidneys, and 29 weeks for liver. CONCLUSION: Growth patterns and timing of maximal growth for 3-dimensional lean and fat measures, limb and organ volumes differed from patterns revealed by traditional 2-dimensional growth measures, suggesting these parameters reflect unique facets of fetal growth. Growth in these three-dimensional measures may be altered by genetic, nutritional, metabolic, or environmental influences and pregnancy complications, in ways not identifiable using corresponding 2-dimensional measures. Further investigation into the relationships of these 3-dimensional standards to abnormal fetal growth, adverse perinatal outcomes, and health status in postnatal life is warranted.
RESUMEN
OBJECTIVE: To analyse trends, risk factors and adverse outcomes associated with antenatal pyelonephritis hospitalisations. DESIGN: Retrospective cohort. SETTING: A national sample of US delivery hospitalisations with associated antenatal hospitalisations. POPULATION: US delivery hospitalisations in the Nationwide Readmissions Database from 2010 to 2020. METHODS: Antenatal hospitalisations with a pyelonephritis diagnosis within the 9 months before delivery hospitalisation were analysed. Clinical, demographic and hospital risk factors associated with antenatal pyelonephritis hospitalisations were analysed with unadjusted and adjusted logistic regression models with unadjusted and adjusted odds ratios as measures of effect. Temporal trends in antenatal pyelonephritis hospitalisations were analysed with Joinpoint regression to determine the relative measure of average annual percent change (AAPC). Risk for severe maternal morbidity and sepsis during antenatal pyelonephritis hospitalisations was similarly analysed with Joinpoint regression. RESULTS: Of an estimated 10.2 million delivery hospitalisations, 49 140 (0.48%) had an associated antenatal pyelonephritis hospitalisation. The proportion of deliveries with a preceding antenatal pyelonephritis hospitalisation decreased by 29% from 0.56% in 2010 to 0.40% in 2020 (AAPC -2.9%, 95% CI -4.0% to -1.9%). Antenatal pyelonephritis decreased, but risk for sepsis diagnoses increased during these hospitalisations from 3.7% in 2010 to 18.0% in 2020 (AAPC 17.2%, 95% CI 14.2%-21.1%). Similarly, risk for severe morbidity increased from 2.6% in 2010 to 4.4% in 2020 (AAPC 5.5%, 95% CI 0.8%-10.7%). CONCLUSION: Antenatal pyelonephritis admissions appear to be decreasing in the USA. However, these hospitalisations are associated with a rising risk for sepsis and severe maternal morbidity.
RESUMEN
OBJECTIVE: This study aimed to evaluate trends, risk factors, and outcomes associated with infections and sepsis during delivery hospitalizations in the United States. STUDY DESIGN: The 2000-2020 National Inpatient Sample was used for this repeated cross-sectional analysis. Delivery hospitalizations of patients aged 15 to 54 with and without infection and sepsis were identified. Common infection diagnoses during delivery hospitalizations analyzed included (i) pyelonephritis, (ii) pneumonia/influenza, (iii) endometritis, (iv) cholecystitis, (v) chorioamnionitis, and (vi) wound infection. Temporal trends in sepsis and infection during delivery hospitalizations were analyzed. The associations between sepsis and infection and common chronic health conditions including asthma, chronic hypertension, pregestational diabetes, and obesity were analyzed. The associations between clinical, demographic, and hospital characteristics, and infection and sepsis were determined with unadjusted and adjusted logistic regression models with unadjusted odds ratio (OR) and adjusted odds ratios with 95% confidence intervals as measures of association. RESULTS: An estimated 80,158,622 delivery hospitalizations were identified and included in the analysis, of which 2,766,947 (3.5%) had an infection diagnosis and 32,614 had a sepsis diagnosis (4.1 per 10,000). The most common infection diagnosis was chorioamnionitis (2.7% of deliveries) followed by endometritis (0.4%), and wound infections (0.3%). Infection and sepsis were more common in the setting of chronic health conditions. Evaluating trends in individual infection diagnoses, endometritis and wound infection decreased over the study period both for patients with and without chronic conditions, while risk for pyelonephritis and pneumonia/influenza increased. Sepsis increased over the study period for deliveries with and without chronic condition diagnoses. Risks for adverse outcomes including mortality, severe maternal morbidity, the critical care composite, and acute renal failure were all significantly increased in the presence of sepsis and infection. CONCLUSION: Endometritis and wound infections decreased over the study period while risk for sepsis increased. Infection and sepsis were associated with chronic health conditions and accounted for a significant proportion of adverse obstetric outcomes including severe maternal morbidity. KEY POINTS: · Sepsis increased over the study period for deliveries with and without chronic condition diagnoses.. · Endometritis and wound infection decreased over the study period.. · Infection and sepsis accounted for a significant proportion of adverse obstetric outcomes..
RESUMEN
OBJECTIVE: Gastroschisis is a full-thickness congenital defect of the abdominal wall through which intestines and other organs may herniate. In a prior analysis, attempted vaginal delivery with fetal gastroschisis appeared to increase through 2013, although cesarean delivery remained common. The objective of this analysis was to update current trends in attempted vaginal birth among pregnancies complicated by gastroschisis. STUDY DESIGN: We performed an updated cross-sectional analysis of live births from 2014 and 2020 using data from the U.S. National Vital Statistics System and evaluated trends in attempted vaginal deliveries among births with gastroschisis. Trends were evaluated using joinpoint regression. We constructed logistic regression models to evaluate the association between demographic and clinical variables and attempted vaginal delivery in the setting of gastroschisis. RESULTS: Among 5,355 deliveries with gastroschisis meeting inclusion criteria, attempted vaginal delivery increased significantly from 68.9% to 75.1%, an average annual percent change of 1.7% (95% confidence interval [CI], 0.8-2.5). Among gastroschisis-complicated pregnancies, patients 35 to 39 years old (adjusted odds ratio [aOR], 0.53; 95% CI, 0.37-0.79) and Hispanic race/ethnicity (aOR, 0.69; 95% CI, 0.58-0.62) were at lower likelihood of attempted vaginal delivery in adjusted analyses. CONCLUSION: These findings suggest that vaginal delivery continues to increase in the setting of gastroschisis. Further reduction of surgical delivery for this fetal defect may be possible. KEY POINTS: · Vaginal deliveries increased among gastroschisis pregnancies.. · Hispanic patients were less likely to attempt vaginal delivery.. · Some gastroschisis pregnancies still deliver surgically..

CONTEXT: Guidelines recommend use of population- and trimester-specific thyroid-stimulating hormone (TSH) and free thyroxine (FT4) reference intervals (RIs) in pregnancy. Since these are often unavailable, clinicians frequently rely on alternative diagnostic strategies. We sought to quantify the diagnostic consequences of current recommendations. METHODS: We included cohorts participating in the Consortium on Thyroid and Pregnancy. Different approaches were used to define RIs: a TSH fixed upper limit of 4.0 mU/L (fixed limit approach), a fixed subtraction from the upper limit for TSH of 0.5 mU/L (subtraction approach) and using nonpregnancy RIs. Outcome measures were sensitivity and false discovery rate (FDR) of women for whom levothyroxine treatment was indicated and those for whom treatment would be considered according to international guidelines. RESULTS: The study population comprised 52 496 participants from 18 cohorts. Compared with the use of trimester-specific RIs, alternative approaches had a low sensitivity (0.63-0.82) and high FDR (0.11-0.35) to detect women with a treatment indication or consideration. Sensitivity and FDR to detect a treatment indication in the first trimester were similar between the fixed limit, subtraction, and nonpregnancy approach (0.77-0.11 vs 0.74-0.16 vs 0.60-0.11). The diagnostic performance to detect overt hypothyroidism, isolated hypothyroxinemia, and (sub)clinical hyperthyroidism mainly varied between FT4 RI approaches, while the diagnostic performance to detect subclinical hypothyroidism varied between the applied TSH RI approaches. CONCLUSION: Alternative approaches to define RIs for TSH and FT4 in pregnancy result in considerable overdiagnosis and underdiagnosis compared with population- and trimester-specific RIs. Additional strategies need to be explored to optimize identification of thyroid dysfunction during pregnancy.

OBJECTIVE: To assess trends and outcomes associated with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS) during US delivery hospitalizations. STUDY DESIGN: The National Inpatient Sample from 2000 to 2019 was used for this repeated cross-sectional analysis. We identified delivery hospitalizations with and without SLE. Temporal trends in SLE during delivery hospitalizations were determined using joinpoint regression. Adjusted logistic regression models accounting for demographic, clinical, and hospital factors were used to determine adjusted odds ratios (aORs) for adverse outcomes based on the presence or absence of SLE. RESULTS: Of an estimated 76 698 775 delivery hospitalizations identified in the NIS, 79386 (0.10%) had an associated diagnosis of SLE. Over the study period, SLE increased from 6.7 to 14.6 cases per 10 000 delivery hospitalizations (average annual percent change 4.5%, 95% CI 4.0-5.1). Deliveries with SLE had greater odds of non-transfusion severe morbidity (aOR 2.21, 95% CI 2.00, 2.44) and underwent a larger absolute increase in morbidity risk over the study period. SLE was associated with a range of other adverse outcomes including preterm delivery, eclampsia, cesarean delivery, and blood transfusion. CONCLUSION: The proportion of deliveries to women with SLE has increased over time in the US, and SLE and APS are associated with a broad range of adverse outcomes.

OBJECTIVE: To evaluate the prevalence, timing, clinical risk factors, and adverse outcomes associated with postpartum readmissions for maternal sepsis. METHODS: We conducted a retrospective cohort study of delivery hospitalizations and 60-day postpartum readmissions for females aged 15-54 years with and without sepsis using the 2016-2020 Nationwide Readmissions Database. Temporal trends in sepsis diagnoses during delivery hospitalizations and 60-day postpartum readmissions were analyzed with the National Cancer Institute's Joinpoint Regression Program to estimate the average annual percent change with 95% CIs. Logistic regression models were fit to determine whether delivery hospitalization characteristics were associated with postpartum sepsis readmissions, and unadjusted and adjusted odds ratios with 95% CIs were reported. Adverse outcomes associated with sepsis during delivery hospitalization and readmission were described, including death, severe morbidity, a critical care composite, and renal failure. RESULTS: Overall, 15,268,190 delivery hospitalizations and 256,216 associated 60-day readmissions were included after population weighting, of which 16,399 (1.1/1,000 delivery hospitalizations) had an associated diagnosis of sepsis at delivery, and 20,130 (1.3/1,000 delivery hospitalizations) had an associated diagnosis of sepsis with postpartum readmission. A sepsis diagnosis was present in 7.9% of all postpartum readmissions. Characteristics associated with postpartum sepsis readmission included younger age at delivery, Medicaid insurance, lowest median ZIP code income quartile, and chronic medical conditions such as obesity, pregestational diabetes, and chronic hypertension. Postpartum sepsis readmissions were associated with infection during the delivery hospitalization, including intra-amniotic infection or endometritis, wound infection, and delivery sepsis. Sepsis diagnoses were associated with 24.4% of maternal deaths at delivery and 38.4% postpartum, 2.2% cases of nontransfusion severe morbidity excluding sepsis at delivery and 13.6% postpartum, 15.6% of critical care composite diagnoses at delivery and 30.1% postpartum, and 11.1% of acute renal failure diagnoses at delivery and 36.4% postpartum. CONCLUSION: Sepsis accounts for a significant proportion of postpartum readmissions and is a major contributor to adverse outcomes during delivery hospitalizations and postpartum readmissions.

OBJECTIVE: To evaluate risk for peripartum cardiomyopathy during delivery and postpartum hospitalizations, and analyze associated trends, risk factors, and clinical outcomes. METHODS: The 2010-2020 Nationwide Readmissions Database was used for this retrospective cohort study. Delivery hospitalizations along with postpartum readmissions occurring within five months of delivery discharge were analyzed. Risk factors associated with peripartum cardiomyopathy were analyzed with unadjusted and adjusted logistic regression models with odds ratios as measures of effect. Risk for severe adverse outcomes associated with peripartum cardiomyopathy was analyzed. Trends were analyzed with joinpoint regression. RESULTS: Of 39,790,772 delivery hospitalizations identified, 9,210 were complicated by a diagnosis of peripartum cardiomyopathy (2.3 per 10,000). Risk for a 5-month readmission with a peripartum cardiomyopathy diagnosis was 4.8 per 10,000. Factors associated with peripartum cardiomyopathy during deliveries included preeclampsia with severe features (OR 18.9, 95 % CI 17.2, 20.7), preeclampsia without severe features (OR 6.9, 95 % CI 6.1, 7.8), multiple gestation (OR 4.7, 95 % CI 4.1, 5.3), chronic hypertension (OR 10.1, 95 % CI 8.9, 11.3), and older maternal age. Associations were attenuated but retained significance in adjusted models. Similar estimates were found when evaluating associations with postpartum readmissions. Peripartum cardiomyopathy readmissions were associated with 10 % of overall postpartum deaths, 21 % of cardiac arrest/ventricular fibrillation diagnoses, 18 % of extracorporeal membrane oxygenation cases, and 40 % of cardiogenic shock. In joinpoint analysis, peripartum cardiomyopathy increased significantly during delivery hospitalizations (average annual percent change [AAPC] 2.2 %, 95 % CI 1.0 %, 3.4 %) but not postpartum readmissions (AAPC 0.0 %, 95 % CI -1.6 %, 1.6 %). CONCLUSION: Risk for peripartum cardiomyopathy increased during delivery hospitalizations over the study period. Obstetric conditions such as preeclampsia and chronic medical conditions that are increasing in prevalence in the obstetric population were associated with the highest odds of peripartum cardiomyopathy.

OBJECTIVE: This study aimed to evaluate cesarean rates and risk for obstetric complications among deliveries with a history of prior uterine surgery. STUDY DESIGN: This serial cross-sectional study analyzed deliveries with and without prior uterine surgery in the 2016-2019 Nationwide Inpatient Sample. Unadjusted and adjusted logistic regression models were performed to assess risk of nontransfusion severe maternal morbidity (SMM) and other obstetric complications based on the presence or absence of prior uterine surgery with unadjusted and adjusted odds ratios (aORs) with 95% confidence intervals (CIs) as measures of association. Adjusted models accounted for demographic, hospital, and delivery factors. Demographics and clinical factors among deliveries with and without a prior history of uterine surgery diagnosis were compared with the chi-square test with p < 0.05 considered statistically significant. RESULTS: Of 14.7 million delivery hospitalization identified, 6,910 (4.7 per 10,000) had a history of uterine surgery and 111,710 (0.76%) experienced SMM. Women with prior uterine surgery were more likely to be older, to be of unknown race or ethnicity, and to have private insurance (p < 0.01 for all). Eighty-five percent of deliveries with prior uterine surgery were performed by cesarean compared with 32% of deliveries without prior uterine surgery (p < 0.01). In adjusted analysis, compared with patients without prior uterine surgery, patients with prior uterine surgery were not at increased risk for SMM (aOR 1.23, 95% CI 0.73-2.07). Evaluating obstetric complications, patients with prior uterine surgery had a decreased risk of postpartum hemorrhage (aOR 0.64, 95% CI 0.43-0.96) and an increased risk of peripartum hysterectomy (aOR 4.12, 95% CI 1.75-9.67), and no difference in other obstetric complications assessed. CONCLUSION: These findings suggest that current clinical practice results in similar delivery risks among patients with compared with without prior uterine surgery. KEY POINTS: · Risk for most adverse outcomes is similar among patients with prior uterine surgery.. · Risk for peripartum hysterectomy was higher with prior uterine surgery.. · Risk for SMM was not higher with prior uterine surgery..
RESUMEN
OBJECTIVE: Given that updated estimates of Ehlers-Danlos syndrome and risks for obstetric complications including postpartum readmission may be of public health significance, we sought to analyze associated obstetric trends and outcomes in a nationally representative population. STUDY DESIGN: The 2016 to 2020 Nationwide Readmissions Database was used for this retrospective cohort study. Delivery hospitalizations to women aged 15 to 54 with and without Ehlers-Danlos syndrome were identified. Temporal trends in Ehlers-Danlos syndrome diagnoses during delivery hospitalizations were analyzed using joinpoint regression to estimate the average annual percent change with 95% confidence intervals (CIs). To determine whether adverse obstetric outcomes during the delivery were associated with Ehlers-Danlos syndrome, unadjusted and adjusted logistic regression models were fit with unadjusted (odds ratio [OR]) and adjusted ORs with 95% CIs as measures of association. In addition to analyzing adverse delivery outcomes, risk for 60-day postpartum readmission was analyzed. RESULTS: An estimated 18,214,542 delivery hospitalizations were included of which 7,378 (4.1 per 10,000) had an associated diagnosis of Ehlers-Danlos syndrome. Ehlers-Danlos syndrome diagnosis increased from 2.7 to 5.2 per 10,000 delivery hospitalization from 2016 to 2020 (average annual percent change increase of 16.1%, 95% CI: 9.4%, 23.1%). Ehlers-Danlos syndrome was associated with increased odds of nontransfusion severe maternal morbidity (OR: 1.84, 95% CI: 1.38, 2.45), cervical insufficiency (OR: 2.14, 95% CI: 1.46, 3.13), postpartum hemorrhage (OR: 1.41, 95% CI: 1.17, 1.68), cesarean delivery (OR: 1.26, 95% CI: 1.17, 1.36), and preterm delivery (OR: 1.35, 95% CI: 1.16, 1.56). Estimates for transfusion, placental abruption, and placenta previa did not differ significantly. Risk for 60-day postpartum readmission was 3.0% among deliveries with Ehlers-Danlos (OR: 1.76, 95% CI: 1.37, 2.25). CONCLUSION: Ehlers-Danlos syndrome diagnoses approximately doubled over the 5-year study period and was associated with a range of adverse obstetric outcomes and complications during delivery hospitalizations as well as risk for postpartum readmission. KEY POINTS: · Ehlers-Danlos syndrome diagnoses approximately doubled over the 5-year study period.. · Ehlers-Danlos was associated with a range of adverse obstetric outcomes.. · Ehlers-Danlos was associated with increased readmission risk..
RESUMEN
INTRODUCTION: We examined the associations of baseline telomere length (TL) and TL change with cognitive function over time in older US adults, as well as differences by sex and race. METHODS: A total of 1820 cognitively healthy individuals (median baseline age: 63 years) were included. Telomere length was measured using qPCR-based method at baseline and among 614 participants in the follow-up examination 10 years later. Cognitive function was assessed by a four-test battery every 2 years. RESULTS: In multivariable-adjusted linear mixed models, longer baseline TL and smaller attrition/lengthening of TL over time were associated with better Animal Fluency Test score. Longer baseline TL was also linearly associated with better Letter Fluency Test score. The observed associations were consistently more pronounced in women than men and in Black compared to White participants. DISCUSSION: Telomere length may be a biomarker that predicts long-term verbal fluency and executive function, particularly in women and Black Americans.

OBJECTIVE: To assess clinical characteristics, trends, and outcomes associated with the diagnosis of hepatitis C virus (HCV) infection during pregnancy. METHODS: This cross-sectional study analyzed delivery hospitalizations using the National Inpatient Sample. Temporal trends in both diagnosis of HCV infection and clinical characteristics associated with HCV infection were analyzed using joinpoint regression to estimate the average annual percent change (AAPC) with 95% CIs. Survey-adjusted logistic regression models were fit to assess the association among HCV infection and preterm delivery, cesarean delivery, and severe maternal morbidity (SMM), adjusting for clinical, medical, and hospital factors with adjusted odds ratios (aORs) as the measure of association. RESULTS: An estimated 76.7 million delivery hospitalizations were included, in which 182,904 (0.24%) delivering individuals had a diagnosis of HCV infection. The prevalence of HCV infection diagnosed in pregnancy increased nearly 10-fold over the study period, from 0.05% in 2000 to 0.49% in 2019, representing an AAPC of 12.5% (95% CI 10.4-14.8%). The prevalence of clinical characteristics associated with HCV infection also increased over the study period, including opioid use disorder (from 10 cases/10,000 birth hospitalizations to 71 cases/10,000 birth hospitalizations), nonopioid substance use disorder (from 71 cases/10,000 birth hospitalizations to 217 cases/10,000 birth hospitalizations), mental health conditions (from 219 cases/10,000 birth hospitalizations to 1,117 cases/10,000), and tobacco use (from 61 cases/10,000 birth hospitalizations to 842 cases/10,000). The rate of deliveries among patients with two or more clinical characteristics associated with HCV infection increased from 26 cases per 10,000 birth hospitalizations to 377 cases per 10,000 delivery hospitalizations (AAPC 13.4%, 95% CI 12.1-14.8%). In adjusted analyses, HCV infection was associated with increased risk for SMM (aOR 1.78, 95% CI 1.61-1.96), preterm birth (aOR 1.88, 95% CI 1.8-1.95), and cesarean delivery (aOR 1.27, 95% CI 1.23-1.31). CONCLUSION: Diagnosis of HCV infection is increasingly common in the obstetric population, which may reflect an increase in screening or a true increase in prevalence. The increase in HCV infection diagnoses occurred in the setting of many baseline clinical characteristics that are associated with HCV infection becoming more common.

BACKGROUND: With improved therapies, an increasing number of patients with Fontan circulation reach reproductive age. Pregnant patients with Fontan circulation are at high risk of obstetrical complications. Most data for pregnancies complicated by Fontan circulation and associated complications stem from single-center studies, with limited national epidemiologic data available. OBJECTIVE: This study aimed to evaluate temporal trends in deliveries to pregnant individuals with Fontan palliation using nationwide data and to estimate associated obstetrical complications among these deliveries. STUDY DESIGN: Delivery hospitalizations were abstracted from the 2000 to 2018 Nationwide Inpatient Sample. Deliveries complicated by Fontan circulation were identified using diagnosis codes, and trends in the rates of these deliveries were assessed using joinpoint regression. Baseline demographics and obstetrical outcomes (including severe maternal morbidity, a composite of serious obstetrical and cardiac complications) were assessed. Univariable log-linear regression models were fit comparing risks of outcomes among deliveries of patients with and without Fontan circulation. RESULTS: A total of 509 pregnancies complicated by Fontan circulation were identified at a rate of 7 per 1 million delivery hospitalizations, with a temporal increase from 2.4 to 30.3 cases per 1 million from 2000 to 2018 (P<.01). Deliveries complicated by Fontan circulation were at higher risk of hypertensive disorders (relative risk, 1.79; 95% confidence interval, 1.42-2.27), preterm delivery (relative risk, 2.37; 95% confidence interval, 1.90-2.96), postpartum hemorrhage (relative risk, 4.28; 95% confidence interval, 3.35-5.45), and severe maternal morbidity (relative risk, 6.09; 95% confidence interval, 4.54-8.17) than deliveries not complicated by Fontan circulation. CONCLUSION: The rates of deliveries of patients with Fontan palliation are increasing on a national level. These deliveries have higher risks of obstetrical complications and severe maternal morbidity. Additional national clinical data are necessary to better understand the complications in pregnancies complicated by Fontan circulation, to improve patient counseling, and to reduce maternal morbidity.

Importance: Reducing rates of unnecessary cesarean deliveries is both a national and a global health objective. However, there are limited national US data on trends in indications for low-risk cesarean delivery. Objective: To determine temporal trends in and indications for cesarean delivery among patients at low risk for the procedure over a 20-year period. Design, Setting, and Participants: This cross-sectional study analyzed 2000 to 2019 delivery hospitalizations using the National Inpatient Sample. Births at low risk for cesarean delivery were identified using a definition from the Society for Maternal-Fetal Medicine and additional criteria. Temporal trends in cesarean birth were analyzed using joinpoint regression to estimate the average annual percentage change (AAPC) with 95% CIs. Data analysis was performed from August 2022 to January 2023. Exposure: This analysis evaluated cesarean birth trends in a population at low risk for this procedure over a 20-year period. Main Outcomes and Measures: In addition to overall cesarean birth risk, cesarean deliveries for nonreassuring fetal status and labor arrest were individually analyzed. Results: Of an estimated 76.7 million delivery hospitalizations, 21.5 million were excluded according to the Society for Maternal-Fetal Medicine definition, and 14.7 million were excluded according to additional criteria. Of the estimated 40â¯517â¯867 deliveries included, 12.1% (4â¯885â¯716 deliveries) were by cesarean delivery. Cesarean deliveries among patients at low risk for the procedure increased from 9.7% to 13.9% between 2000 and 2009, plateaued, and then decreased from 13.0% to 11.1% between 2012 and 2019. The AAPC for cesarean delivery was 6.4% (95% CI, 5.2% to 7.6%) from 2000 to 2005, 1.2% from 2005 to 2009 (95% CI, -1.2% to 3.7%), and -2.2% from 2009 to 2019 (95% CI, -2.7% to -1.8%). Cesarean delivery for nonreassuring fetal status increased from 3.4% of all deliveries in 2000 to 5.1% in 2019 (AAPC, 2.1%; 95% CI, 1.7% to 2.5%). Cesarean delivery for labor arrest increased from 3.6% in 2000 to a peak of 4.8% in 2009 before decreasing to 2.7% in 2019. Cesarean deliveries for labor arrest increased during the first half of the study (2000-2009) for the active phase (from 1.5% to 2.1%), latent phase (from 1.1% to 1.5%), and second stage (from 0.9% to 1.3%) and then decreased from 2010 to 2019, from 2.1% to 1.7% for the active phase, from 1.5% to 1.2% for the latent phase, and from 1.2% to 0.9% for the second stage. Conclusions and Relevance: Cesarean deliveries among patients at low risk for cesarean birth appeared to decrease over the latter years of the study period, with cesarean deliveries for labor arrest becoming less common.

BACKGROUND: Population-level data on obstructive sleep apnea among pregnant women in the United States and associated risk for adverse outcomes during delivery may be of clinical importance and public health significance. OBJECTIVE: This study aimed to assess trends in and outcomes associated with obstructive sleep apnea during delivery hospitalizations. STUDY DESIGN: This repeated cross-sectional study analyzed delivery hospitalizations using the National Inpatient Sample. Temporal trends in obstructive sleep apnea were analyzed using joinpoint regression to estimate the average annual percentage change with 95% confidence intervals. Survey-adjusted logistic regression models were fit to assess the association between obstructive sleep apnea and mechanical ventilation or tracheostomy, acute respiratory distress syndrome, hypertensive disorders of pregnancy, peripartum hysterectomy, pulmonary edema/heart failure, stillbirth, and preterm birth. RESULTS: From 2000 to 2019, an estimated 76,753,013 delivery hospitalizations were identified, of which 54,238 (0.07%) had a diagnosis of obstructive sleep apnea. During the study period, the presence of obstructive sleep apnea during delivery hospitalizations increased from 0.4 to 20.5 cases per 10,000 delivery hospitalizations (average annual percentage change, 20.6%; 95% confidence interval, 19.1-22.2). Clinical factors associated with obstructive sleep apnea included obesity (4.3% of women without and 57.7% with obstructive sleep apnea), asthma (3.2% of women without and 25.3% with obstructive sleep apnea), chronic hypertension (2.0% of women without and 24.5% with obstructive sleep apnea), and pregestational diabetes mellitus (0.9% of women without and 10.9% with obstructive sleep apnea). In adjusted analyses accounting for obesity, other clinical factors, demographics, and hospital characteristics, obstructive sleep apnea was associated with increased odds of mechanical ventilation or tracheostomy (adjusted odds ratio, 21.9; 95% confidence interval, 18.0-26.7), acute respiratory distress syndrome (adjusted odds ratio, 5.9; 95% confidence interval, 5.4-6.5), hypertensive disorders of pregnancy (adjusted odds ratio, 1.6; 95% confidence interval, 1.6-1.7), stillbirth (adjusted odds ratio, 1.2; 95% confidence interval, 1.0-1.4), pulmonary edema/heart failure (adjusted odds ratio, 3.7; 95% confidence interval, 2.9-4.7), peripartum hysterectomy (adjusted odds ratio, 1.66; 95% confidence interval, 1.23-2.23), and preterm birth (adjusted odds ratio, 1.2; 95% confidence interval, 1.1-1.2). CONCLUSION: Obstructive sleep apnea diagnoses are increasingly common in the obstetrical population and are associated with a range of adverse obstetrical outcomes during delivery hospitalizations.

BACKGROUND: Up-to-date data on population-level risk factors for postpartum psychosis is limited, although increasing substance use disorders, psychiatric disorders, autoimmune disorders, and other medical comorbidities in the obstetrical population may be contributing to the increased baseline risk of postpartum psychosis. OBJECTIVE: This study aimed to determine trends in and risk factors for postpartum psychosis during delivery hospitalizations and postpartum readmissions. STUDY DESIGN: Analyzing the 2016-2019 Nationwide Readmission Database, this repeated cross-sectional study identified diagnoses of postpartum psychosis during delivery hospitalizations and postpartum readmissions within 60 days of discharge. The relationship among demographic, clinical, and hospital-level factors present at delivery and postpartum psychosis was analyzed with logistic regression models with adjusted odds ratios with 95% confidence intervals as measures of association. Separate models were created for postpartum psychosis diagnoses at delivery and during postpartum readmission. Temporal trends in diagnoses were analyzed with Joinpoint regression to determine the average annual percent change with 95% confidence intervals. RESULTS: Of 12,334,506 deliveries in the analysis, 13,894 (1.1 per 1000) had a diagnosis of postpartum psychosis during the delivery hospitalization, and 7128 (0.6 per 1000) had a 60-day postpartum readmission with postpartum psychosis. Readmissions with postpartum psychosis increased significantly during the study period (P=.046). Most readmissions with a postpartum psychosis diagnosis occurred in 0 to 10 days (43% of readmissions) or 11 to 20 days (18% of readmissions) after discharge. Clinical factors with the highest adjusted odds for postpartum psychosis readmission included delivery postpartum psychosis (adjusted odds ratio, 5.8; 95% confidence interval, 4.2-8.0), depression disorder (adjusted odds ratio, 3.7; 95% confidence interval, 3.3-4.2), bipolar spectrum disorder (odds ratio, 2.9; 95% confidence interval, 2.3-3.5), and schizophrenia spectrum disorder (adjusted odds ratio, 2.9; 95% confidence interval, 2.1-4.0). In models analyzing postpartum psychosis diagnoses at delivery, risk factors associated with the highest odds included anxiety disorder (adjusted odds ratio, 3.9; 95% confidence interval, 3.5-4.2), schizophrenia spectrum disorder (adjusted odds ratio, 2.5; 95% confidence interval, 1.9-3.4), bipolar disorder (adjusted odds ratio, 1.8; 95% confidence interval, 1.6-2.1), stillbirth (odds ratio, 3.6; 95% confidence interval, 3.1-4.2), and substance use disorder (odds ratio, 1.7; 95% confidence interval, 1.6-1.9). In addition, chronic conditions, such as pregestational diabetes mellitus, obesity, and substance use, were associated with delivery and readmission postpartum psychosis. CONCLUSION: This study determined that postpartum psychosis is increasing during postpartum readmissions and is associated with a wide range of obstetrical and medical comorbidities. Close follow-up care after delivery for other medical and obstetrical diagnoses may represent an opportunity to identify postpartum psychiatric conditions, including postpartum psychosis.

BACKGROUND: Management of postpartum stroke has been the focus of several quality improvement efforts in the past decade. However, there is little recent national trends data for postpartum stroke readmissions. OBJECTIVE: This study aimed to determine trends, risk factors, and complications associated with postpartum stroke readmission. STUDY DESIGN: The 2013 to 2019 Nationwide Readmissions Database was used to perform a retrospective cohort study that evaluated the risk for readmission for stroke within 60 days of delivery hospitalization discharge. Temporal trends in readmissions were analyzed using the National Cancer Institute's Joinpoint Regression Program to estimate the average annual percent change with 95% confidence intervals. Stratified trends were analyzed for hemorrhage stroke, ischemic stroke, and stroke readmissions at 1 to 10, 11 to 30, and 31 to 60 days after delivery discharge. Risk factors for stroke were analyzed using unadjusted and adjusted logistic regression models with odds ratios and 95% confidence intervals as measures of association. The risk for stroke complications, including mechanical ventilation, seizures, death, and a prolonged stay ≥14 days, was analyzed. RESULTS: Of an estimated 21,754,603 delivery hospitalizations, 5006 were complicated by a 60-day postpartum readmission with a diagnosis of stroke. The average annual percent change for all stroke readmissions over the study period was not significant (average annual percent change, 0.1%; 95% confidence interval, -2.2% to 2.4%). When the trends in readmission for ischemic and hemorrhagic stroke were analyzed, the results were similar, as were the stratified analyses by readmission timing. Risk factors associated with increased odds included superimposed preeclampsia (odds ratio, 4.8; 95% confidence interval, 3.9-5.9), preeclampsia with severe features (odds ratio, 3.7; 95% confidence interval, 3.0-4.4), maternal cardiac disease (odds ratio, 3.0; 95% confidence interval, 2.5-3.7), chronic kidney disease (odds ratio, 5.0; 95% confidence interval, 3.4-7.5), and lupus (odds ratio, 7.0; 95% confidence interval, 4.9-10.2). Risk was retained in adjusted analyses. Common stroke-related complications included a prolonged hospital stay ≥14 days (12.1 per 1000 stroke-related readmissions), seizures (9.9 per 1000 stroke-related readmissions), and mechanical ventilation (6.6 per 1000 stroke-related readmissions). CONCLUSION: This analysis of nationally representative data demonstrated no change in the rate of 60-day postpartum hospitalizations for stroke from 2013 to 2019. Further clinical research is indicated to optimize risk reduction for stroke after delivery hospitalization discharge.

OBJECTIVE: To determine whether longitudinal health data accounts for end-organ injury or death in the setting of chronic hypertension. DESIGN: Cohort of 64 799 deliveries to 61 854 women. SETTING: US claims data for the preiod 2008-2019. POPULATION: Women with a delivery hospitalisation and chronic hypertension. METHODS: Risk for a composite of acute end-organ injury or death during the delivery hospitalisation and 30 days postpartum was analysed. Adjusted logistic regression models were derived with discrimination for each model estimated by the C-statistic. Poisson regression was used to estimate adjusted risk ratios. Starting with models using data from pregnancy, further adjustment was performed accounting for healthcare use in the year prior to pregnancy, including hospitalisations, emergency department encounters, prescription medications and pre-pregnancy diagnoses. MAIN OUTCOME MEASURES: Acute end-organ injury or death. RESULTS: The composite outcome occurred among 5.7% of 64 799 deliveries. For patients with commercial insurance, filling non-hypertensive medications from ≥11 different classes, compared with none (adjusted risk ratio, aRR 4.07, 95% CI 2.86-5.79), three or more hospitalisations before pregnancy, compared with none (aRR 4.75, 95% CI 3.46-6.52), and chronic kidney disease diagnosed in the year before pregnancy (aRR 2.35, 95% CI 1.88, 2.94) were associated with increased risk. For pregnancies covered by commercial insurance, the C-statistic increased from 0.615 (95% CI 0.599-0.630) in the model with pregnancy data only to 0.796 (95% CI 0.783-0.808) for the model additionally including healthcare use in the year before pregnancy. Findings with Medicaid were similar. CONCLUSIONS: Prepregnancy care use predicted adverse maternal outcomes. These data may be important in risk stratification.
