ABSTRACT
Importance: The influence of the COVID-19 pandemic on fertility rates has been suggested in the lay press and anticipated based on documented decreases in fertility and pregnancy rates during previous major societal and economic shifts. Anticipatory planning for birth rates is important for health care systems and government agencies to accurately estimate size of economy and model working and/or aging populations. Objective: To use projection modeling based on electronic health care records in a large US university medical center to estimate changes in pregnancy and birth rates prior to and after the COVID-19 pandemic societal lockdowns. Design, Setting, and Participants: This cohort study included all pregnancy episodes within a single US academic health care system retrospectively from 2017 and modeled prospectively to 2021. Data were analyzed September 2021. Exposures: Pre- and post-COVID-19 pandemic societal shutdown measures. Main Outcomes and Measures: The primary outcome was number of new pregnancy episodes initiated within the health care system and use of those episodes to project birth volumes. Interrupted time series analysis was used to assess the degree to which COVID-19 societal changes may have factored into pregnancy episode volume. Potential reasons for the changes in volumes were compared with historical pregnancy volumes, including delays in starting prenatal care, interruptions in reproductive endocrinology and infertility services, and preterm birth rates. Results: This cohort study documented a steadily increasing number of pregnancy episodes over the study period, from 4100 pregnancies in 2017 to 4620 in 2020 (28â¯284 total pregnancies; median maternal [interquartile range] age, 30 [27-34] years; 18â¯728 [66.2%] White women, 3794 [13.4%] Black women; 2177 [7.7%] Asian women). A 14% reduction in pregnancy episode initiation was observed after the societal shutdown of the COVID-19 pandemic (risk ratio, 0.86; 95% CI, 0.79-0.92; P < .001). This decrease appeared to be due to a decrease in conceptions that followed the March 15 mandated COVID-19 pandemic societal shutdown. Prospective modeling of pregnancies currently suggests that a birth volume surge can be anticipated in summer 2021. Conclusions and Relevance: This cohort study using electronic medical record surveillance found an initial decline in births associated with the COVID-19 pandemic societal changes and an anticipated increase in birth volume. Future studies can further explore how pregnancy episode volume changes can be monitored and birth rates projected in real-time during major societal events.

Introduction: The management of nephrolithiasis during pregnancy can be stressful for urologists due to concerns for investigations and treatments that may pose risk of fetal harm, and unfamiliarity with optimal management of these complex patients. In response, we created multi-disciplinary evidence-based guidelines to standardize the care for obstetric patients presenting with flank pain and suspicion for nephrolithiasis. Methods: A multi-disciplinary team involving Urology, Obstetric Anesthesiology, Obstetrics and Gynecology, Diagnostic Radiology, and Interventional Radiology from a single academic medical center was assembled. A PubMed search was performed using keywords of pregnancy/antepartum, nephrolithiasis/calculi/kidney stones, ureteroscopy, non-obstetric surgery, complications, preterm delivery, MRI, computerized tomography, renal bladder ultrasound (RBUS), and anesthesia to identify relevant articles. Team members reviewed their respective areas to create a comprehensive set of guidelines. One invited external expert reviewed the guidelines for validation purposes. Results: A total of 54 articles were reviewed for evidence synthesis. Four guideline statements were constructed to guide diagnosis and imaging, and seven statements to guide intervention. Guidelines were then used to create a diagnostic and intervention flowchart for ease of use. In summary, RBUS should be the initial diagnostic study. If diagnostic uncertainty still exists, a non-contrast CT scan should be obtained. For obstetric patients presenting with a septic obstructing stone, urgent decompression should be achieved. We recommend ureteral stent placement as the preferred intervention if local factors allow. Conclusions: We present a standardized care pathway for the management of nephrolithiasis during pregnancy. Our aim is to standardize and simplify the clinical management of these complex scenarios for urologists.

BACKGROUND: Multiple users access computer workstations in busy clinical settings, requiring many logins throughout the day as users switch from one computer to another. This can lead to workflow inefficiencies as well as security concerns resulting from users sharing login sessions to save time. Proximity cards and readers have the potential to improve efficiency and security by allowing users to access clinical workstations simply by bringing the card near the reader, without the need for manual entry of a username and password. OBJECTIVES: To assess the perceived impact of proximity cards and readers for rapid user authentication to clinical workstations in the setting of an existing electronic health record with single sign-on software already installed. METHODS: Questionnaires were administered to clinical faculty and staff five months before and three months after the installation of proximity card readers in an inpatient birthing center and an outpatient obstetrics clinic. Open-ended feedback was also collected and qualitatively analyzed. RESULTS: There were 71 and 33 responses to the pre- and post-implementation surveys, respectively. There was a significant increase in the perceived speed of login with the proximity cards, and a significant decrease in the self-reported occurrence of shared login sessions between users. Feedback regarding the system was mostly positive, although several caveats were noted, including minimal benefit when used with an obstetric application that did not support single sign-on. CONCLUSIONS: Proximity cards and readers, along with single sign-on software, have the potential to enhance workflow efficiency by allowing for faster login times and diminish security concerns by reducing shared logins on clinical workstations. The positive feedback was used by our health system leadership to support the expanded implementation of the proximity card readers throughout the clinical setting.

OBJECTIVE: To evaluate whether amniotic fluid markers can aid the decision of whether to retain or remove a cervical cerclage after preterm premature rupture of membranes (PPROM). METHODS: A retrospective cohort study included pregnancies involving PPROM after diagnostic amniocentesis and cerclage placement. Cerclage was retained for more than 12 hours after PPROM in the study group (n=18); the comparison group comprised women who underwent immediate cerclage removal after PPROM (n=22). Analyses were performed using concentrations of interleukin (IL)-6, glucose, and white blood cells (WBCs) in the amniotic fluid to measure relationships with adverse outcomes. RESULTS: The latency period from PPROM to delivery was significantly shorter in the group that underwent immediate cerclage removal (P<0.005). Latency periods of more than 48 hours (P<0.001) and more than 7 days (P<0.01), and chorioamnionitis (P<0.05) were associated with cerclage retention. Neonatal outcomes were not significantly different between the study group and the comparison group. However, elevated IL-6 levels were associated with cumulative neonatal morbidity (P<0.05). Low IL-6 (P<0.001) and WBC (P<0.05) levels were significantly associated with a latency period of more than 7 days. CONCLUSION: Amniotic fluid levels of IL-6 and WBCs may be of clinical value for individualizing the management of patients with PPROM after cerclage.

Posttraumatic stress disorder (PTSD) is associated with gastrointestinal and genitourinary comorbidities. These map onto the somatization disorder symptoms in the Diagnostic and Statistical Manual of Mental Disorders ( American Psychiatric Association, 1994 ) and the dissociative (conversion) disorders symptoms in the International Classification of Diseases taxonomy ( World Health Organization, 2007 ). Hyperemesis gravidarum (HG) is one of these symptoms and a gastrointestinal comorbidity of PTSD occurring in pregnancy. It is an idiopathic condition defined as severe vomiting with dehydration, metabolic imbalance, wasting, and hospital care seeking. HG is more severe than the normative phenomenon of nausea and vomiting of pregnancy. This test-of-concept pilot (N = 25) explored the hypothesis that there is a trauma-related subtype of HG characterized by (a) high levels of dissociative symptoms and (b) altered plasma concentrations of oxytocin. This hypothesis is informed by a theory of posttraumatic oxytocin dysregulation that posits altered oxytocin function as a mechanism of gut smooth muscle peristalsis dysfunction. A 4-group analysis compared controls with nausea and vomiting of pregnancy (NV only) and cases with HG only, NV and PTSD, or HG and PTSD. Oxytocin was correlated with the nausea and vomiting symptom severity score (r = .464, p = .019) and with the dissociation symptom score (r = .570, p = .003). Women in the group with both PTSD and HG (the trauma-related HG subtype) had the highest levels of dissociation and the highest levels of oxytocin. A linear regression model indicated that the independent association of the trauma-related HG subtype with oxytocin level was mediated by high levels of dissociative symptoms.

BACKGROUND: Complete hydatiform mole and coexistent viable fetus is very rare. The use of a cervical cerclage for cervical indications in the presence of this condition has never been reported. Although the diagnosis was made postnatal, the objective is to present a case with good neonatal outcome. CASE PRESENTATION: A patient presented with vaginal spotting around 23 weeks. She has a history of four preterm deliveries. Her cervix was dilated and a cerclage was placed. She presented again with PPROM around 25 weeks. She went into spontaneous preterm labor and delivered a viable fetus that is a healthy girl today. Eventually the pathology of the placenta showed a complete hydatidiform mole. CONCLUSION: It is necessary to inform patients about the potential risks and poor outcomes of this condition. For those who desire all potential interventions, cerclage placement could be considered.

Fetal cardiac intervention for critical aortic stenosis (AS) with evolving hypoplastic left heart syndrome is performed in an attempt to maintain a biventricular circulation postnatally. The procedure has been hindered by technical challenges and poor candidate selection. We report here the novel use of a pressure guidewire during aortic valvuloplasty in a fetus at 21 weeks' gestation with critical AS and evolving hypoplastic left heart syndrome. Use of a pressure guidewire during fetal cardiac intervention offers several potential advantages over existing protocols. This technique augments fetal ultrasound as it relates to operator awareness of catheter and wire position (with continuous monitoring of pressure waveforms), improves on intraprocedural fetal hemodynamic monitoring and responsiveness to resuscitation, and provides a rich new data set of invasive fetal hemodynamics. This data set offers tremendous potential with regards to improving candidate selection and postintervention prognostication. In addition, we provide the first, to our knowledge, characterization of intracardiac pressures in a human fetus with congenital heart disease. Given the realized and potential benefits associated with this technique, use of a pressure guidewire may become standard of care for all fetal cardiac interventions.

A second trimester fetal demise followed influenza-like illness in early pregnancy. Influenza A virus (H1N1) was identified in maternal and fetal tissue, confirming transplacental passage. These findings suggested a causal relationship between early exposure and fetal demise. Management of future influenza outbreaks should include evaluation of products of conception associated with fetal loss.

INTRODUCTION: The purpose of this study was to redress weaknesses in past studies of a psychogenic etiology for hyperemesis gravidarum (HG) by (1) estimating from a known population what proportion of HG cases also have psychiatric diagnoses, (2) determining if psychiatric disorder preceded HG, and (3) re-considering whether non-pregnancy somatic conditions also precede HG. METHODS: We analyzed insurance data for all 11,016 members who gave birth to singletons in 2000-2004, 208 of whom had HG. RESULTS: Prevalence of HG was 1.8% overall, 3.8% with one psychiatric diagnosis, 5.8% with >1 psychiatric diagnosis. One in 10 HG cases had pre-pregnancy depression, anxiety, or substance abuse diagnoses. One in five HG cases had either a psychiatric or a somatic condition (e.g., chronic pelvic pain, dysmenorrhea) diagnosis prior to pregnancy. Pre-pregnancy psychiatric diagnosis doubled the adjusted odds of HG. Combined psychiatric and somatic diagnoses quadrupled the adjusted odds of HG. DISCUSSION: Vomiting is a non-specific sign that may have multiple etiologies. For 10-20% of HG sufferers, vomiting may be a physical comorbidity of a psychiatric condition occurring in the context of pregnancy. Psychobiological research with HG cases with past or current psychiatric diagnoses is needed to consider plausible mechanisms.

In 2004, the Department of Obstetrics and Gynecology at the University of Michigan decided to stop offering routine circumcision for specialty and disciplinary, logistic, and educational reasons. The Pediatric Hospitalist Service assumed responsibility for the procedures and the educational process with resultant patient and staff satisfaction, educational, logistical and economic benefits.

The objective of this study was to compare length of gestation, fetal growth, and birthweight by race/ethnicity and pregravid weight groups in twin pregnancies. Three thousand and thirty-six twin pregnancies of 28 weeks or more gestation were divided by race/ethnicity (White, Black and Hispanic), and pregravid body mass index (BMI) groups (less than 25.0 vs. 25.0 or more). Outcomes were modeled using multiple regression, controlling for confounders, with White non-Hispanic women as the reference group. Hispanic women had the highest average birthweight and the longest gestation, as well as the lowest proportions of low birthweight, very low birthweight, preterm and early preterm births of the 3 race/ethnicity groups. In the multivariate analyses, Hispanic women had significantly longer gestations (by 7.8 days) and faster rates of fetal growth midgestation (20 to 28 weeks, by 17.4 g/week) and late gestation (after 28 weeks, by 5.3 g/week), whereas Black women had significantly slower rates of fetal growth (by 5.7 g/week and by 4.5 g/week, respectively). These findings in twins reflect the racial and ethnic disparities previously shown in singletons, including the Hispanic paradox of longer gestations and higher rates of fetal growth.

The objective of the study was to test the hypothesis that changes in arm anthropometry can be used to determine the risk of faltering growth in twin gestations. Serial data on midupper arm circumference (MUAC) and maternal weight gain were collected from a sample of 156 mothers. Changes in MUAC were monitored from 20 to 34 weeks. Women with a large loss of MUAC (greater than 1.5 cm), particularly when it occurred within two to four weeks of delivery, were significantly heavier, had higher pregravid Body Mass Indexes (BMIs), but gained less weight than mothers with no change in MUAC. In analysis of covariance models adjusting for length of gestation, black ethnicity, males per twin pair, monochorionicity, and baseline MUAC at 20 weeks, a large loss of MUAC was associated with significantly lower birthweight (2263 g vs. 2499 g) and birthweight z-score (-0.92 SDU vs. -0.39 SDU). Changes in MUAC from 20 to 34 weeks, and especially near delivery, are significantly associated with fetal growth in twin pregnancies. A positive change may indicate that the mother has adequate dietary intake or nutrient stores to continue to accrue lean body mass and support fetal growth, while a loss of MUAC indicates that dietary intake or nutrient stores may be inadequate. This simple, relatively precise, measure of change in maternal body composition during pregnancy may be useful in identifying twin pregnancies at risk for faltering intrauterine growth, particularly among overweight or obese women.

OBJECTIVE: The purpose of this study was to evaluate factors affecting birth charges in twin pregnancies. STUDY DESIGN: Clinical and financial data were obtained on 1486 twin pregnancies delivered between 1995 to 2002 at medical centers in Maryland, Florida, Michigan, and South Carolina. Maternal and neonatal length of stay (LOS) and charges were modeled by gestational age and other risk factors using a general linear model. RESULTS: Maternal and infant birth admission LOS and charges increased significantly with a decline in gestational age. Maternal LOS and charges were also significantly increased by cesarean delivery and preeclampsia. Newborn LOS and charges increased significantly by monochorionicity and slowed growth between 20 to 28 weeks. For mother and infants, the shortest LOS and lowest birth charges were at 37 to 38 weeks. CONCLUSION: These findings reflect the substantial maternal and neonatal morbidity associated with twin pregnancies, and demonstrate that 37 to 38 weeks is their optimal gestation.

BACKGROUND: The minimum local analgesic concentration has been defined as the median effective local analgesic concentration (EC50) in a 20-ml volume for epidural analgesia in the first stage of labor. The aim of this study was to assess the relative analgesic potencies of epidural levobupivacaine and ropivacaine by determination of their respective minimum local analgesic concentrations. METHODS: Parturients at 7 cm of cervical dilation or less who requested epidural analgesia were allocated to one of two groups in this double-blind, randomized, prospective study. After lumbar epidural catheter placement, 20 ml of the test solution was given: levobupivacaine (n = 35) or ropivacaine (n = 35). The concentration of local anesthetic was determined by the response of the previous patient in that group to a higher or lower concentration using up-down sequential allocation. Analgesic efficacy was assessed using 100-mm visual analog pain scale scores, with 10 mm or less within 30 min defined as effective. An effective result directed a 0.01% wt/vol decrement for the next patient. An ineffective result directed a 0.01% wt/vol increment. RESULTS: Of 105 women enrolled, 35 were excluded, leaving 70 for analysis. The minimum local analgesic concentration of levobupivacaine was 0.087% wt/vol (95% CI, 0.081-0.094%), and the minimum local analgesic concentration of ropivacaine was 0.089% wt/vol (95% CI, 0.075-0.103%). Levobupivacaine and ropivacaine were of similar potency with a ropivacaine:levobupivacaine potency ratio of 0.98 (95% CI, 0.80-1.20). No difference in motor effects was observed. CONCLUSIONS: This study demonstrated that levobupivacaine and ropivacaine are of similar potency for epidural analgesia in the first stage of labor.

OBJECTIVE: This study was undertaken to evaluate the effect of a prenatal nutrition and education program on twin pregnancy, neonatal, and early childhood outcomes. STUDY DESIGN: This prospective intervention study of women who participated in a specialized program (Program Pregnancies) versus nonparticipants included twice-monthly visits, dietary prescription of 3000 to 4000 kcal per day, multimineral supplementation, and patient education. RESULTS: Program Pregnancies were associated with improved pregnancy outcomes (preeclampsia, adjusted odds ratio [AOR] 0.41, 95% CI, 0.23-0.75; preterm premature rupture of membranes, AOR 0.35, 95% CI, 0.20-0.60; delivery <36 weeks, AOR 0.62, 95% CI, 0.43-0.89; low birth weight, AOR 0.42, 95% CI, 0.29-0.61), significantly longer gestations (+7.6 days), higher birth weights (+220 g), lower neonatal morbidity (retinopathy of prematurity, necrotizing enterocolitis, intraventricular hemorrhage, or ventilator support, AOR 0.44, 95% CI, 0.31-0.62), length of stay (-5.3 days), and cost per twin (-14,023 dollars). Through 3 years of age, program children were significantly less likely to be rehospitalized (AOR 0.31, 95% CI, 0.11-0.91) or to be developmentally delayed (AOR 0.65, 95% CI, 0.44-0.96). CONCLUSION: Program participation was associated with improved outcomes at birth and through age 3 years.

OBJECTIVE: The purpose of this study was to evaluate the associations between maternal factors and outcomes in triplet pregnancies. STUDY DESIGN: This was a historic cohort study of 194 triplet pregnancies of >or=24 weeks of gestation that were delivered from 1983 through 2001 from five medical centers. RESULTS: In analyses that were limited to pregnancies with all live-born triplets (178 pregnancies), women with a previous good outcome (>2500 g + >37 weeks of gestation) had longer gestations (+7.9 days, P =.03), better rates of fetal growth (+4.9 g/wk, P <.0001), and higher birth weights (+153 g, P <.0001). Maternal weight gains of <36 pounds by 24 weeks of gestation were associated with lower birth weights (-197 g, P <.0001), and fetal growth rates at Subject(s)

ABSTRACT
BACKGROUND: The minimum local analgesic concentration (MLAC) has been defined as the median effective local analgesic concentration in a 20-ml volume for epidural analgesia in the first stage of labor. The aim of this study was to determine the local anesthetic-sparing efficacy of epidural epinephrine by its effect on the MLAC of bupivacaine. METHODS: In this double-blind, randomized, prospective study, 70 parturients who were at 7 cm or less cervical dilation and who requested epidural analgesia were allocated to one of two groups. After lumbar epidural catheter placement, 20 ml bupivacaine (n = 35) or bupivacaine with epinephrine 1:300,000 (n = 35) was administered. The concentration of bupivacaine was determined by the response of the previous patient in that group to a higher or lower concentration using up-down sequential allocation. Analgesic efficacy was assessed using 100-mm visual analog pain scores, with 10 mm or less within 30 min defined as effective. RESULTS: The MLAC of bupivacaine alone was 0.091% wt/vol (95% confidence interval, 0.081-0.102). The addition of epinephrine 1:300,000 (66.7 microg) resulted in a significant reduction (P < 0.01) in the MLAC of bupivacaine to 0.065% wt/vol (95% confidence interval, 0.047-0.083). The lowest maternal blood pressure was significantly lower in the bupivacaine-epinephrine group (P = 0.03). There were statistically significant reductions in fetal heart rate (P = 0.011) in the bupivacaine-epinephrine group that were not clinically significant. CONCLUSIONS: The addition of epidural epinephrine 1:300,000 (66 microg) resulted in a significant 29% reduction in the MLAC of bupivacaine. Coincident reductions in fetal heart rate and maternal blood pressure were also observed that were not clinically significant.
