  Abstract

  Biologic strain such as oxidative stress has been associated with short leukocyte telomere length (LTL), as well as with preeclampsia and spontaneous preterm birth, yet little is known about their relationships with each other. We investigated associations of postpartum maternal LTL with preeclampsia and spontaneous preterm birth.This pilot nested case control study included independent cohorts of pregnant people with singleton gestations from two academic institutions: Cohort 1 (hereafter referred to as Suburban) were enrolled prior to 20 weeks' gestation between 2012 and 2018; and Cohort 2 (hereafter referred to as Urban) were enrolled at delivery between 2000 and 2012. Spontaneous preterm birth or preeclampsia were the selected pregnancy complications and served as cases. Cases were compared with controls from each study cohort of uncomplicated term births. Blood was collected between postpartum day 1 and up to 6 months postpartum and samples were frozen, then simultaneously thawed for analysis. Postpartum LTL was the primary outcome, measured using quantitative polymerase chain reaction (PCR) and compared using linear multivariable regression models adjusting for maternal age. Secondary analyses were done stratified by mode of delivery and self-reported level of stress during pregnancy.156 people were included; 66 from the Suburban Cohort and 90 from the Urban Cohort. The Suburban Cohort was predominantly White, Hispanic, higher income and the Urban Cohort was predominantly Black, Haitian, and lower income. We found a trend towards shorter LTLs among people with preeclampsia in the Urban Cohort (6517 versus 6913 bp, p = 0.07), but not in the Suburban Cohort. There were no significant differences in LTLs among people with spontaneous preterm birth compared to term controls in the Suburban Cohort (6044 versus 6144 bp, p = 0.64) or in the Urban Cohort (6717 versus 6913, p = 0.37). No differences were noted by mode of delivery. When stratifying by stress levels in the Urban Cohort, preeclampsia was associated with shorter postpartum LTLs in people with moderate stress levels (p = 0.02).Our exploratory results compare postpartum maternal LTLs between cases with preeclampsia or spontaneous preterm birth and controls in two distinct cohorts. These pilot data contribute to emerging literature on LTLs in pregnancy.

  Abstract

  Recent studies have suggested that pregnancy accelerates biologic aging, yet little is known about how biomarkers of aging are affected by events during the peripartum period. Given that immune shifts are known to occur following surgery, we explored the relation between mode of delivery and postpartum maternal leukocyte telomere length (LTL), a marker of biologic aging.Postpartum maternal blood samples were obtained from a prospective cohort of term, singleton livebirths without hypertensive disorders or peripartum infections between 2012 and 2018. The primary outcome was postpartum LTLs from one blood sample drawn between postpartum week 1 and up to 6 months postpartum, measured from thawed frozen peripheral blood mononuclear cells using quantitative PCR in basepairs (bp). Multivariable linear regression models compared LTLs between vaginal versus cesarean births, adjusting for age, body mass index, and nulliparity as potential confounders. Analyses were conducted in two mutually exclusive groups: those with LTL measured postpartum week 1 and those measured up to 6 months postpartum. Secondarily, we compared multiomics by mode of delivery using machine-learning methods to evaluate whether other biologic changes occurred following cesarean. These included transcriptomics, metabolomics, microbiomics, immunomics, and proteomics (serum and plasma).Of 67 included people, 50 (74.6 %) had vaginal and 17 (25.4 %) had cesarean births. LTLs were significantly shorter after cesarean in postpartum week 1 (5755.2 bp cesarean versus 6267.8 bp vaginal, p = 0.01) as well as in the later draws (5586.6 versus 5945.6 bp, p = 0.04). After adjusting for confounders, these differences persisted in both week 1 (adjusted beta -496.1, 95 % confidence interval [CI] -891.1, -101.1, p = 0.01) and beyond (adjusted beta -396.8; 95 % CI -727.2, -66.4. p = 0.02). Among the 15 participants who also had complete postpartum multiomics data available, there were predictive signatures of vaginal versus cesarean births in transcriptomics (cell-free [cf]RNA), metabolomics, microbiomics, and proteomics that did not persist after false discovery correction.Maternal LTLs in postpartum week 1 were nearly 500 bp shorter following cesarean. This difference persisted several weeks postpartum, even though other markers of inflammation had normalized. Mode of delivery should be considered in any analyses of postpartum LTLs and further investigation into this phenomenon is warranted.

• Outcome of pregnancy oral glucose tolerance test and preterm birth. Epidemiology (Cambridge, Mass.) Liang, R., Panelli, D. M., Stevenson, D. K., Rehkopf, D. H., Shaw, G. M., Sørensen, H. T., Pedersen, L. 2024

  Abstract

  Gestational diabetes is associated with adverse outcomes such as preterm birth (<37 weeks). However, there is no international consensus on screening criteria or diagnostic levels for gestational diabetes, and it is unknown whether body mass index (BMI) or obesity modifies the relation between glucose level and preterm birth.We studied a pregnancy cohort restricted to two Danish regions from the linked Danish Medical Birth Register to study associations between glucose measurements from the 2-hour post-load 75-gram oral glucose tolerance test (one-step approach) and preterm birth from 2004-2018. In Denmark, gestational diabetes screening is a targeted strategy for mothers with identified risk factors. We used Poisson regression to estimate rate ratios (RR) of preterm birth with z-standardized glucose measurements. We assessed effect measure modification by stratifying analyses and testing for heterogeneity.Among 11,337 pregnancies (6.2% delivered preterm), we observed an adjusted preterm birth RR of 1.2 (95% CI: 1.1-1.3) for a 1 standard deviation glucose increase of 1.4 mmol/L from the mean 6.7 mmol/L. There was evidence for effect measure modification by obesity, e.g., adjusted RR for non-obese (BMI <30): 1.2 (95%CI: 1.1-1.3) vs. obese (BMI ≥30): 1.3 (95%CI: 1.2-1.5), P=0.05 for heterogeneity.Among mothers screened for gestational diabetes, increased glucose levels, even those below the diagnostic level for gestational diabetes in Denmark, were associated with increased preterm birth risk. Obesity (BMI ≥30) may be an effect measure modifier, not just a confounder, of the relation between blood glucose and preterm birth risk.

• Associations between anxiety, sleep, and blood pressure parameters in pregnancy: a prospective pilot cohort study. BMC pregnancy and childbirth Miller, H. E., Simpson, S. L., Hurtado, J., Boncompagni, A., Chueh, J., Shu, C. H., Barwick, F., Leonard, S. A., Carvalho, B., Sultan, P., Aghaeepour, N., Druzin, M., Panelli, D. M. 2024; 24 (1): 366

  Abstract

  The potential effect modification of sleep on the relationship between anxiety and elevated blood pressure (BP) in pregnancy is understudied. We evaluated the relationship between anxiety, insomnia, and short sleep duration, as well as any interaction effects between these variables, on BP during pregnancy.This was a prospective pilot cohort of pregnant people between 23 to 36 weeks' gestation at a single institution between 2021 and 2022. Standardized questionnaires were used to measure clinical insomnia and anxiety. Objective sleep duration was measured using a wrist-worn actigraphy device. Primary outcomes were systolic (SBP), diastolic (DBP), and mean (MAP) non-invasive BP measurements. Separate sequential multivariable linear regression models fit with generalized estimating equations (GEE) were used to separately assess associations between anxiety (independent variable) and each BP parameter (dependent variables), after adjusting for potential confounders (Model 1). Additional analyses were conducted adding insomnia and the interaction between anxiety and insomnia as independent variables (Model 2), and adding short sleep duration and the interaction between anxiety and short sleep duration as independent variables (Model 3), to evaluate any moderating effects on BP parameters.Among the 60 participants who completed the study, 15 (25%) screened positive for anxiety, 11 (18%) had subjective insomnia, and 34 (59%) had objective short sleep duration. In Model 1, increased anxiety was not associated with increases in any BP parameters. When subjective insomnia was included in Model 2, increased DBP and MAP was significantly associated with anxiety (DBP: β 6.1, p = 0.01, MAP: β 6.2 p < 0.01). When short sleep was included in Model 3, all BP parameters were significantly associated with anxiety (SBP: β 9.6, p = 0.01, DBP: β 8.1, p < 0.001, and MAP: β 8.8, p < 0.001). No moderating effects were detected between insomnia and anxiety (p interactions: SBP 0.80, DBP 0.60, MAP 0.32) or between short sleep duration and anxiety (p interactions: SBP 0.12, DBP 0.24, MAP 0.13) on BP.When including either subjective insomnia or objective short sleep duration, pregnant people with anxiety had 5.1-9.6 mmHg higher SBP, 6.1-8.1 mmHg higher DBP, and 6.2-8.8 mmHg higher MAP than people without anxiety.

• Evaluation of Sleep in Pregnant Inpatients Compared With Outpatients. Obstetrics and gynecology Panelli, D. M., Miller, H. E., Simpson, S. L., Hurtado, J., Shu, C. H., Boncompagni, A. C., Chueh, J., Barwick, F., Carvalho, B., Sultan, P., Aghaeepour, N., Druzin, M. L. 2024

  Abstract

  To evaluate whether antepartum hospitalization was associated with differences in sleep duration or disrupted sleep patterns.This was a prospective cohort study with enrollment of pregnant people aged 18-55 years with singleton gestations at 16 weeks of gestation or more between 2021 and 2022. Each enrolled antepartum patient was matched by gestational age to outpatients recruited from obstetric clinics at the same institution. Participants responded to the ISI (Insomnia Severity Index) and wore actigraph accelerometer watches for up to 7 days. The primary outcome was total sleep duration per 24 hours. Secondary outcomes included sleep efficiency (time asleep/time in bed), ISI score, clinical insomnia (ISI score higher than 15), short sleep duration (less than 300 minutes/24 hours), wakefulness after sleep onset, number of awakenings, and sleep fragmentation index. Outcomes were evaluated with multivariable generalized estimating equations adjusted for body mass index (BMI), sleep aid use, and insurance type, accounting for gestational age correlations. An interaction term assessed the joint effects of time and inpatient status.Overall 58 participants were included: 18 inpatients and 40 outpatients. Inpatients had significantly lower total sleep duration than outpatients (mean 4.4 hours [SD 1.6 hours] inpatient vs 5.2 hours [SD 1.5 hours] outpatient, adjusted β=-1.1, 95% CI, -1.8 to -0.3, P=.01). Awakenings (10.1 inpatient vs 13.8, P=.01) and wakefulness after sleep onset (28.3 inpatient vs 35.5 outpatient, P=.03) were lower among inpatients. There were no differences in the other sleep outcomes, and no interaction was detected for time in the study and inpatient status. Inpatients were more likely to use sleep aids (39.9% vs 12.5%, P=.03).Hospitalized pregnant patients slept about 1 hour/day less than outpatients. Fewer awakenings and reduced wakefulness after sleep onset among inpatients may reflect increased use of sleep aids in hospitalized patients.

• Physical activity among pregnant inpatients and outpatients and associations with anxiety. European journal of obstetrics, gynecology, and reproductive biology Panelli, D. M., Miller, H. E., Simpson, S. L., Hurtado, J., Shu, C. H., Boncompagni, A. C., Chueh, J., Carvalho, B., Sultan, P., Aghaeepour, N., Druzin, M. L. 2024; 297: 8-14

  Abstract

  Physical activity is linked to lower anxiety, but little is known about the association during pregnancy. This is especially important for antepartum inpatients, who are known to have increased anxiety yet may not be able to achieve target levels of physical activity during hospitalization. We compared physical activity metrics between pregnant inpatients and outpatients and explored correlations with anxiety.This was a prospective cohort between 2021 and 2022 of pregnant people aged 18-55 years carrying singleton gestations ≥ 16 weeks. Three exposure groups were matched for gestational age: 1) outpatients from general obstetric clinics; 2) outpatients from high-risk Maternal-Fetal Medicine obstetric clinics; and 3) antepartum inpatients. Participants wore Actigraph GT9X Link accelerometer watches for up to 7 days to measure physical activity. The primary outcome was mean daily step count. Secondary outcomes were metabolic equivalent tasks (METs), hourly kilocalories (kcals), moderate to vigorous physical activity (MVPA) bursts, and anxiety (State-Trait Anxiety Inventory [STAI]). Step counts were compared using multivariable generalized estimating equations adjusting for maternal age, body-mass index, and insurance type as a socioeconomic construct, accounting for within-group clustering by gestational age. Spearman correlations were used to correlate anxiety scores with step counts.58 participants were analyzed. Compared to outpatients, inpatients had significantly lower mean daily steps (primary outcome, adjusted beta -2185, 95 % confidence interval [CI] -3146, -1224, p < 0.01), METs (adjusted beta -0.18, 95 % CI -0.23, -0.13, p < 0.01), MVPAs (adjusted beta -38.2, 95 % CI -52.3, -24.1, p < 0.01), and kcals (adjusted beta -222.9, 95 % CI -438.0, -7.8, p = 0.04). Over the course of the week, steps progressively decreased for inpatients (p-interaction 0.01) but not for either of the outpatient groups. Among the entire cohort, lower step counts correlated with higher anxiety scores (r = 0.30, p = 0.02).We present antenatal population norms and variance for step counts, metabolic equivalent tasks, moderate to vigorous physical activity bursts, and kcals, as well as correlations with anxiety. Antepartum inpatients had significantly lower physical activity than outpatients, and lower step counts correlated with higher anxiety levels. These results highlight the need for physical activity interventions, particularly for hospitalized pregnant people.

• Mental health conditions and contraception: current landscape, reproductive health and obstetric outcomes, and clinical guidance. Current opinion in obstetrics & gynecology Miller, H. E., Kruger, S. L., Panelli, D. M. 2024

  Abstract

  This review presents the epidemiology of mental health conditions among reproductive aged people, common adverse reproductive outcomes, the hormonal profile of contraception and its relationship with psychiatric outcomes, and updated information for clinicians providing contraceptive counselling for this population.There is variability among contraceptive behaviours and patterns across those who have mental health conditions, impacting reproductive, psychiatric, and perinatal outcomes. The endocrinology of hormonal contraceptives is well understood, however, the impacts of steroidal hormones on mental health outcomes continue to be less understood. Overall, hormonal contraceptives are safe to use among those with mental health conditions, and among those using selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors. Additional considerations are needed when prescribing contraception among people who may be at risk of poor adherence, who use certain classes of antidepressants, antipsychotics, antiepileptics, and who are <6 weeks postpartum.Barriers to effective contraceptive use should be addressed and myths on negative psychiatric impacts of hormonal contraceptives should be dispelled. Healthcare clinicians should seek out opportunities to become proficient in contraception counselling to improve health outcomes among people with mental health conditions.

• An exploratory analysis of factors associated with spontaneous preterm birth among pregnant veterans with post-traumatic stress disorder. Women's health issues : official publication of the Jacobs Institute of Women's Health Panelli, D. M., Chan, C. S., Shaw, J. G., Shankar, M., Kimerling, R., Frayne, S. M., Herrero, T. C., Lyell, D. J., Phibbs, C. S. 2023; 33 (2): 191-198

  Abstract

  Pregnant veterans with post-traumatic stress disorder (PTSD) are at increased risk for spontaneous preterm birth, yet the underlying reasons are unclear. We examined factors associated with spontaneous preterm birth among pregnant veterans with active PTSD.This was an observational study of births from administrative databases reimbursed by the Veterans Health Association (VA) between 2005 and 2015. Singleton livebirths among veterans with active PTSD within 12 months prior to childbirth were included. The primary outcome was spontaneous preterm birth. Maternal demographics, psychiatric history, and pregnancy complications were evaluated as exposures. Covariates significant on bivariate analysis, as well as age and race/ethnicity as a social construct, were included in multivariable logistic regression to identify factors associated with spontaneous preterm birth. Additional analyses stratified significant covariates by the presence of active concurrent depression and explored interactions between antidepressant use and preeclampsia.Of 3,242 eligible births to veterans with active PTSD, 249 (7.7%) were spontaneous preterm births. The majority of veterans with active PTSD (79.1%) received some type of mental health treatment, and active concurrent depression was prevalent (61.4%). Preeclampsia/eclampsia (adjusted odds ratio [aOR] 3.30, 95% confidence interval [CI] 1.67-6.54) and ≥6 antidepressant medication dispensations within 12 months prior to childbirth (aOR 1.89, 95% CI 1.29-2.77) were associated with spontaneous preterm birth. No evidence of interaction was seen between antidepressant use and preeclampsia on spontaneous preterm birth (p=0.39). Findings were similar when stratified by active concurrent depression.Among veterans with active PTSD, preeclampsia/eclampsia and ≥6 antidepressant dispensations were associated with spontaneous preterm birth. While the results do not imply that people should discontinue needed antidepressants during pregnancy in veterans with PTSD, research into these factors might inform preterm birth prevention strategies for this high-risk population.

• A systematic review of patient-reported outcome measures used in maternal postpartum anxiety. American journal of obstetrics & gynecology MFM O'Carroll, J., Ando, K., Yun, R., Panelli, D., Nicklin, A., Kennedy, N., Carvalho, B., Blake, L., Coker, J., Kaysen, D., Sultan, P. 2023: 101076

  Abstract

  To perform a systematic review and evaluate the psychometric measurement properties of instruments in postpartum anxiety using Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines and identify the best available patient-reported outcome measure.We searched 4 databases (CINAHL, Embase, PubMed, and Web of Science in July 2022) including studies which evaluated at least one psychometric measurement property of a patient reported outcome measurement instrument. The protocol was registered with PROSPERO CRD42021260004 and followed the COSMIN guidelines for systematic reviews.Studies eligible for inclusion included those that assessed a patient-reported outcome measure examining postpartum anxiety. We included studies where the instruments had undergone some form of psychometric property assessment in the postpartum maternal population, consisted of at least 2 questions, and were not subscales.This systematic review used COSMIN and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines to identify the best patient reported outcome measurement instrument for postpartum anxiety. A risk of bias assessment was performed, and a modified GRADE approach used to assess the level of evidence with recommendations being made for the overall quality of each instrument.A total of 28 studies evaluating 13 instruments in 10,570 patients were included. Content validity was sufficient in 9, with 5 instruments receiving a class A recommendation (recommended for use). Postpartum Specific Anxiety Scale, Postpartum Specific Anxiety Scale Research Short Form, Postpartum Specific Anxiety Scale Research Short Form Covid, Postpartum Specific Anxiety Scale- Persian and State-Trait Anxiety Inventory demonstrated adequate content validity and sufficient internal consistency. Nine instruments received a recommendation of class B (further research required). No instrument received a class C recommendation (not recommended for use).Five instruments received a class A recommendation, all with limitations such as not being specific to the postpartum population, not assessing all domains, lacking generalizability or evaluation of cross-cultural validity. There is currently no freely available instrument assessing all domains of postpartum anxiety. Future studies are needed to determine the optimum current instrument or development and validation of a more specific measure for maternal postpartum anxiety.

• Physical Fitness in Relationship to Depression and Post-Traumatic Stress Disorder During Pregnancy Among U.S. Army Soldiers. Journal of women's health (2002) Panelli, D. M., Nelson, D. A., Wagner, S., Shaw, J. G., Phibbs, C. S., Kurina, L. M. 2023

  Abstract

  Background: Depression and post-traumatic stress disorder (PTSD) are prevalent in pregnancy, especially among military members. These conditions can lead to adverse birth outcomes, yet, there's a paucity of evidence for prevention strategies. Optimizing physical fitness is one understudied potential intervention. We explored associations between prepregnancy physical fitness and antenatal depression and PTSD in soldiers. Materials and Methods: This was a retrospective cohort study of active-duty U.S. Army soldiers with live births between 2011 and 2014, identified with diagnosis codes from inpatient and outpatient care. The exposure was each individual's mean Army physical fitness score from 10 to 24 months before childbirth. The primary outcome was a composite of active depression or PTSD during pregnancy, defined using the presence of a code within 10 months before childbirth. Demographic variables were compared across four quartiles of fitness scores. Multivariable logistic regression models were conducted adjusting for potential confounders selected a priori. A stratified analysis was conducted for depression and PTSD separately. Results: Among 4,583 eligible live births, 352 (7.7%) had active depression or PTSD during pregnancy. Soldiers with the highest fitness scores (Quartile 4) were less likely to have active depression or PTSD in pregnancy (Quartile 4 vs. Quartile 1 adjusted odds ratio 0.55, 95% confidence interval 0.39-0.79). Findings were similar in stratified analyses. Conclusion: In this cohort, the odds of active depression or PTSD during pregnancy were significantly reduced among soldiers with higher prepregnancy fitness scores. Optimizing physical fitness may be a useful tool to reduce mental health burden on pregnancy.

• Clinical and Physician Factors Associated With Failed Operative Vaginal Delivery. Obstetrics and gynecology Panelli, D. M., Leonard, S. A., Joudi, N., Judy, A. E., Bianco, K., Gilbert, W. M., Main, E. K., El-Sayed, Y. Y., Lyell, D. J. 2023

  Abstract

  To examine clinical and physician factors associated with failed operative vaginal delivery among individuals with nulliparous, term, singleton, vertex (NTSV) births.This was a retrospective cohort study of individuals with NTSV live births with an attempted operative vaginal delivery by a physician between 2016 and 2020 in California. The primary outcome was cesarean birth after failed operative vaginal delivery, identified using linked diagnosis codes, birth certificates, and physician licensing board data stratified by device type (vacuum or forceps). Clinical and physician-level exposures were selected a priori, defined using validated indices, and compared between successful and failed operative vaginal delivery attempts. Physician experience with operative vaginal delivery was estimated by calculating the number of operative vaginal delivery attempts made per physician during the study period. Multivariable mixed effects Poisson regression models with robust standard errors were used to estimate risk ratios of failed operative vaginal delivery for each exposure, adjusted for potential confounders.Of 47,973 eligible operative vaginal delivery attempts, 93.2% used vacuum and 6.8% used forceps. Of all operative vaginal delivery attempts, 1,820 (3.8%) failed; the success rate was 97.3% for vacuum attempts and 82.4% for forceps attempts. Failed operative vaginal deliveries were more likely with older patient age, higher body mass index, obstructed labor, and neonatal birth weight more than 4,000 g. Between 2016 and 2020, physicians who attempted more operative vaginal deliveries were less likely to fail. When vacuum attempts were successful, physicians who conducted them had a median of 45 vacuum attempts during the study period, compared with 27 attempts when vacuum attempts were unsuccessful (adjusted risk ratio [aRR] 0.95, 95% CI 0.93-0.96). When forceps attempts were successful, physicians who conducted them had a median of 19 forceps attempts, compared with 11 attempts when forceps attempts were unsuccessful (aRR 0.76, 95% CI 0.64-0.91).In this large, contemporary cohort with NTSV births, several clinical factors were associated with operative vaginal delivery failure. Physician experience was associated with operative vaginal delivery success, more notably for forceps attempts. These results may provide guidance for physician training in maintenance of operative vaginal delivery skills.

• Associations between pregnancy glucose measurements and risk of preterm birth: a retrospective cohort study of commercially insured women in the United States from 2003-2021. Annals of epidemiology Liang, R., Panelli, D. M., Stevenson, D. K., Rehkopf, D. H., Shaw, G. M. 2023

  Abstract

  To investigate associations between glucose measurements during pregnancy and risk of preterm birth (PTB).Retrospective cohort study of commercially insured women with singleton live births in the United States from 2003-2021 using longitudinal medical claims, socioeconomic data, and eight glucose results from different types of fasting and post-load tests performed between 24-28 weeks of gestation for gestational diabetes screening. Risk ratios of PTB (<37 weeks) were estimated via Poisson regression for z-standardized glucose measures. Non-linear relationships for continuous glucose measures were examined via generalized additive models.Elevations in all eight glucose measures were associated with increased risk (adjusted risk ratio point estimates: 1.05-1.19) of PTB for 196,377 women with non-fasting 50-gram glucose challenge test (one glucose result), 31,522 women with complete 100-gram, 3-hour fasting oral glucose tolerance test (OGTT) results (four glucose results), and 10,978 women with complete 75-gram, 2-hour fasting OGTT results (three glucose results). Associations were consistent after adjusting for and stratifying by sociodemographic and clinical factors. Substantial non-linear relationships (U-, J-, and S-shaped) were observed between several glucose measurements and PTB.Elevations in various glucose measures were linearly and non-linearly associated with increased risk of PTB, even before diagnostic thresholds for gestational diabetes.

• Contemporary management of epilepsy in pregnancy. Current opinion in obstetrics & gynecology Darmawan, K. F., Panelli, D. M. 2022

  Abstract

  The number of reproductive aged people with epilepsy in the United States is increasing, making epilepsy during pregnancy more prevalent. Simultaneously, more people are using newer generations of antiseizure medications before, during and after pregnancy. Here, we review current evidence on contemporary management and outcomes of pregnancies among people with epilepsy.This review evaluates recent literature to summarize current practices in preconception counselling, contraception, antiseizure medications before, during and after pregnancy, and peri-partum and postpartum risks in people with epilepsy.With the introduction of newer generation antiseizure medications being used during pregnancy, current literature shows that there may be decreased risk in adverse foetal and maternal outcomes. In the peri-partum and postpartum period, recent literature shows that people with epilepsy have an increased risk of severe maternal morbidity and hospital readmission. Given this, as well as considerations for dosing of antiseizure medications, close surveillance of people with epilepsy during pregnancy is warranted.

• An exploratory analysis of leukocyte telomere length among pregnant and non-pregnant people. Brain, behavior, & immunity - health Panelli, D. M., Diwan, M., Cruz, G. I., Leonard, S. A., Chueh, J., Gotlib, I. H., Bianco, K. 2022; 25: 100506

  Abstract

  Background: Leukocyte telomere length (LTL) is a biomarker that is affected by older age, psychosocial stress, and medical comorbidities. Despite the relevance of these factors to obstetric practice, little is known about LTL in pregnancy. Our study explored longitudinal LTL dynamics in pregnant and non-pregnant people.Objective: This pilot study compares changes in LTL between pregnant and non-pregnant people over time, explores potential correlations between LTL and mental health measures, and investigates associations between short first-trimester LTL and adverse pregnancy outcomes.Study design: This was a prospective pilot cohort study of nulliparous pregnant and non-pregnant people between ages 18 and 50 who presented for care at a single institution from January to November 2020. Pregnant people were enrolled between 10 and 14 weeks gestation. Participants had two blood samples drawn for LTL; the first on the day of enrollment and the second on postpartum day 1 (pregnant cohort) or 7 months later (non-pregnant cohort). LTL was measured using quantitative PCR. The primary outcome was the difference between pregnant and non-pregnant people in LTL change between the two timepoints (basepair difference per 30-day period). Secondary outcomes included differences in responses to the Patient Health Questionnaire-9 (PHQ-9) and a survey about stress related to COVID-19. Differences in LTL were tested using t-tests and linear regression models, both crude and adjusted for age. A subgroup analysis was conducted within the pregnant cohort to examine whether shorter first-trimester LTL was associated with adverse pregnancy outcomes. We conducted t-tests to compare LTL between people with and without each categorical outcome and computed Pearson correlation coefficients between LTL and continuous outcomes such as gestational age at delivery.Results: 46 pregnant and 30 non-pregnant people were enrolled; 44 pregnant and 18 non-pregnant people completed all LTL assessments. There were no between-group differences in LTL change (-4.2±22.2 bp per 30 days pregnant versus -6.4±11.2 bp per 30 days non-pregnant, adjusted beta 2.1, 95% CI -9.0-13.2, p=0.60). The prevalence of depression and pandemic-related stress were both low overall. The two groups did not differ in PHQ-9 scores, and no correlations were significant between LTL and PHQ-9 scores. Among the 44 pregnant people, shorter first-trimester LTL was significantly correlated with earlier gestational age at delivery (r=0.35, p=0.02).Conclusion: In this exploratory pilot cohort of reproductive-aged people with low levels of psychological stress, we described baseline changes in LTL over time in pregnant and non-pregnant participants. We found a correlation between shorter first-trimester LTL and earlier gestational age at delivery, which warrants further investigation in a larger cohort.

• Addressing postpartum contraception practices utilizing a multidisciplinary Pregnancy Heart Team approach. AJOG global reports Miller, H. E., Do, S. C., Cruz, G., Panelli, D. M., Leonard, S. A., Girsen, A., Lee, C. J., Khandelwal, A., Shaw, K. A., Bianco, K. 2022; 2 (4): 100100

  Abstract

  BACKGROUND: Cardiovascular disease has emerged as the leading cause of maternal morbidity and mortality, making planned pregnancy, and thereby reliable contraception among people with cardiovascular disease, vital.OBJECTIVE: This study aimed to compare postpartum contraceptive practices among people with cardiovascular disease (cardiac cohort) cared for by a Pregnancy Heart Team to people with other chronic comorbidities (high-risk cohort), and people without comorbidities (low-risk cohort). We hypothesized that the Pregnancy Heart Team influenced baseline contraception counseling and practices among those with cardiovascular disease.STUDY DESIGN: This was a retrospective cohort study comparing postpartum contraceptive practices between a cardiac cohort who received care by a multidisciplinary team between 2012 and 2020 and high-risk and low-risk cohorts delivering at a single academic center between 2016 and 2019. We investigated presence of a contraceptive plan (at birthing admission, discharge, and postpartum visit) and uptake of reliable contraception by 8 weeks postpartum.RESULTS: We included 1464 people: 189 with cardiovascular disease, 197 with other chronic comorbidities, and 1078 low-risk people. At birth hospitalization admission, reliable contraception was planned among 42% of the cardiac cohort, 40% of the high-risk cohort, and 31% of the low-risk cohort, with similar distributions at the time of discharge and at 8 weeks postpartum.Compared with the cardiac cohort, by 8 weeks postpartum,the high-risk cohort had similar odds of using highly reliable forms of contraception (39% vs 36%; adjusted odds ratio, 0.78; 95% confidence interval, 0.50-1.21) and similar odds of having a plan to use the most reliable forms of contraception (intrauterine device, implant, bilateral tubal ligation) at the time of birthing admission (42% vs 40%; adjusted odds ratio, 0.78; 95% confidence interval, 0.50-1.22), discharge (47% vs 45%; adjusted odds ratio, 0.95; 95% confidence interval, 0.61-1.48), and postpartum visit (35% vs 29%; adjusted odds ratio, 0.76; 95% confidence interval, 0.49-1.17).The low-risk cohort had lower odds of using a reliable form of contraception (39% vs 27%; adjusted odds ratio, 0.53; 95% confidence interval, 0.37-0.75) and was less likely to have a plan for reliable contraception at the time of birthing admission (42% vs 31%; adjusted odds ratio, 0.54; 95% confidence interval, 0.38-0.76), discharge (47% vs 33%; adjusted odds ratio, 0.58; 95% confidence interval, 0.4-0.82), and postpartum visit (35% vs 21%; adjusted odds ratio, 0.50; 95% confidence interval, 0.35-0.71).CONCLUSION: People with cardiovascular disease cared for by a Pregnancy Heart Team had higher odds of reliable postpartum contraception planning and uptake compared with a low-risk cohort and similar odds compared with a high-risk cohort. Pregnancy could serve as a critical period for contraception counseling and family planning among people with cardiovascular disease. A multidisciplinary team should be used to address postpartum contraception as a modifiable risk factor to reduce maternal morbidity and mortality among those with cardiovascular disease.

• Validation of ICD-10-CM Diagnosis Codes for Gestational Age at Birth. Epidemiology (Cambridge, Mass.) Leonard, S. A., Panelli, D. M., Gould, J. B., Gemmill, A., Main, E. K. 2022

  Abstract

  The International Classification of Diseases Clinical Modification 10th Revision (ICD-CM-10) introduced diagnosis codes for week of gestation. Our objective was to assess the validity of these codes among live births, which could have major utility in perinatal research and quality improvement.We used linked birth certificate and patient discharge data from births in California during 2016-2019 (N = 1,843,992). We identified gestational age using Z3A.xx ICD-10-CM diagnosis codes in birthing patient discharge data and compared it with the gold standard of obstetric estimate, as recorded on the birth certificate. We further assessed sensitivity and specificity of gestational age categories (≥37 weeks, <37 weeks, <32 weeks, <28 weeks), given these categories are frequently of interest, and evaluated differences in validity of preterm birth (<37 weeks' gestation) by patient characteristics.1,770,103 patients had a gestational age recorded in patient discharge and birth certificate data. When comparing gestational age in patient discharge data with birth certificate data, the concordance correlation coefficient was 0.96 (95% CI: 0.96, 0.96) and the mean difference between the two measurements was 0.047 (95% CI: 0.046, 0.047) weeks. 95% of the differences between the two measurements were between -1.00 week and +1.09 weeks. Sensitivity and specificity were 0.94 to 1.00 for all gestational age categories and were 0.94 to 1.00 for preterm birth across sociodemographic groups.We found week-specific gestational age at delivery ICD-10-CM diagnosis codes in patient discharge data to have high validity when compared with the best obstetric estimate on the birth certificate.

• Postpartum Readmission for Hypertension After Discharge on Labetalol or Nifedipine. Obstetrics and gynecology Do, S. C., Leonard, S. A., Kan, P., Panelli, D. M., Girsen, A. I., Lyell, D. J., El-Sayed, Y. Y., Druzin, M. L., Herrero, T. 2022

  Abstract

  To assess whether readmission for hypertension by 6 weeks postpartum differed between patients discharged on nifedipine or labetalol.This cohort study included patients with delivery admissions from 2006 to 2017 who were discharged from the hospital on nifedipine or labetalol and were included in a large, national adjudicated claims database. We identified patients' discharge medication based on filled outpatient prescriptions. We compared rates of hospital readmission for hypertension between patients discharged postpartum on labetalol alone, nifedipine alone, or combined nifedipine and labetalol. Patients with chronic hypertension without superimposed preeclampsia were excluded. Comparisons based on medication were performed using logistic regression models with adjustment for prespecified confounders. Comparisons were also stratified by hypertensive disorder of pregnancy severity.Among 1,582,335 patients overall, 14,112 (0.89%) were discharged postpartum on labetalol, 9,001 (0.57%) on nifedipine, and 1,364 (0.09%) on both medications. Postpartum readmissions for hypertension were more frequent for patients discharged on labetalol compared with nifedipine (641 patients vs 185 patients, 4.5% vs 2.1%, adjusted odds ratio [aOR] 1.63, 95% CI 1.43-1.85). Readmissions for hypertension were more frequent for patients discharged on labetalol compared with nifedipine for both mild (4.5% vs 2.7%, aOR 1.57, 95% CI 1.29-1.93) and severe hypertensive disorders of pregnancy (261 patients vs 72 patients, 5.7% vs 3.2%, aOR 1.63, 95% CI 1.43-1.85). Readmissions for hypertension were more frequent on combined nifedipine and labetalol compared with nifedipine (3.1% vs 2.1%), but the odds were lower after confounder adjustment (aOR 0.80, 95% CI 0.64-0.99).Postpartum discharge on labetalol was associated with increased risk of readmission for hypertension compared with discharge on nifedipine.

• Leukocyte telomere dynamics across gestation in uncomplicated pregnancies and associations with stress. BMC pregnancy and childbirth Panelli, D. M., Leonard, S. A., Wong, R. J., Becker, M., Mayo, J. A., Wu, E., Girsen, A. I., Gotlib, I. H., Aghaeepour, N., Druzin, M. L., Shaw, G. M., Stevenson, D. K., Bianco, K. 2022; 22 (1): 381

  Abstract

  Short leukocyte telomere length is a biomarker associated with stress and morbidity in non-pregnant adults. Little is known, however, about maternal telomere dynamics in pregnancy. To address this, we examined changes in maternal leukocyte telomere length (LTL) during uncomplicated pregnancies and explored correlations with perceived stress.In this pilot study, maternal LTL was measured in blood collected from nulliparas who delivered live, term, singleton infants between 2012 and 2018 at a single institution. Participants were excluded if they had diabetes or hypertensive disease. Samples were collected over the course of pregnancy and divided into three time periods: < 200/7 weeks (Timepoint 1); 201/7 to 366/7 weeks (Timepoint 2); and 370/7 to 9-weeks postpartum (Timepoint 3). All participants also completed a survey assessing a multivariate profile of perceived stress at the time of enrollment in the first trimester. LTL was measured using quantitative polymerase chain reaction (PCR). Wilcoxon signed-rank tests were used to compare LTL differences within participants across all timepoint intervals. To determine whether mode of delivery affected LTL, we compared postpartum Timepoint 3 LTLs between participants who had vaginal versus cesarean birth. Secondarily, we evaluated the association of the assessed multivariate stress profile and LTL using machine learning analysis.A total of 115 samples from 46 patients were analyzed. LTL (mean ± SD), expressed as telomere to single copy gene (T/S) ratios, were: 1.15 ± 0.26, 1.13 ± 0.23, and 1.07 ± 0.21 for Timepoints 1, 2, and 3, respectively. There were no significant differences in LTL between Timepoints 1 and 2 (LTL T/S change - 0.03 ± 0.26, p = 0.39); 2 and 3 (- 0.07 ± 0.29, p = 0.38) or Timepoints 1 and 3 (- 0.07 ± 0.21, p = 0.06). Participants who underwent cesareans had significantly shorter postpartum LTLs than those who delivered vaginally (T/S ratio: 0.94 ± 0.12 cesarean versus 1.12 ± 0.21 vaginal, p = 0.01). In secondary analysis, poor sleep quality was the main stress construct associated with shorter Timepoint 1 LTLs (p = 0.02) and shorter mean LTLs (p = 0.03).In this cohort of healthy pregnancies, maternal LTLs did not significantly change across gestation and postpartum LTLs were shorter after cesarean than after vaginal birth. Significant associations between sleep quality and short LTLs warrant further investigation.

• The Loop Electrosurgical Excision Procedure and Cone Conundrum: The Role of Cumulative Excised Depth in Predicting Preterm Birth AJP REPORTS Panelli, D. M., Wood, R. L., Elias, K. M., Growdon, W. B., Kaimal, A. J., Feldman, S., McElrath, T. F. 2022; 12 (01): E41-E48

  Abstract

  Objective  The objective was to determine factors associated with spontaneous preterm birth at less than 37 weeks in a cohort of patients who underwent a loop electrosurgical excision procedure (LEEP) or cone prior to pregnancy. Study Design  This was a nested case-control study within a cohort of patients who underwent at least one LEEP or cone and had care for the next singleton pregnancy at either of two institutions between 1994 and 2014. Cases had spontaneous preterm birth at less than 37 weeks. Exposures included potential risk factors for preterm birth such as cumulative depth of excised cervix and time since excision. Reverse stepwise selection was used to identify the covariates for multivariable logistic regression. Results  A total of 134 patients were included. Eighteen (13%) had a spontaneous preterm birth at less than 37 weeks. Median second-trimester cervical lengths were similar between those who delivered preterm and term (3.9-cm preterm and 3.6-cm term, p  = 0.69). Patients who delivered preterm had a significantly greater median total excised depth of cervix (1.2 vs. 0.8 cm, p  = 0.04). After adjustment for confounders, total excised depth remained significantly associated with preterm birth (adjusted odds ratio [aOR] = 2.2, 95% confidence interval [CI]: 1.3-3.8). Conclusion  Total excised depth should be considered in addition to cervical length screening when managing subsequent pregnancies. Key Points A history of a LEEP or cone excision has been associated with spontaneous preterm birth.A two-fold increase in spontaneous preterm birth was seen per cumulative centimeter excised.There was no difference in second-trimester cervical length between the term and preterm groups.

• Clinical factors associated with a positive postpartum depression screen in people with cardiac disease during pregnancy. Current research in psychiatry Panelli, D. M., Sherwin, E. B., Lee, C. J., Leonard, S. A., Miller, S. E., Miller, H. E., Tolani, A. T., Hoover, V., Ansari, J. R., Khandelwal, A., Bianco, K. 2022; 2 (2): 25-29

  Abstract

  Background: While people with cardiac disease are known to be at increased lifetime risk of depression, little is known about postpartum depression rates in this population. Describing rates of positive postpartum depression screens and identifying risk factors that are unique to cardiac patients may help inform risk reduction strategies.Methods: This retrospective cohort study included pregnant patients with congenital and/or acquired cardiac disease who delivered at a single institution between 2014 and 2020. The primary outcome was a positive postpartum depression screen, defined as Edinburgh Postpartum Depression Score (EPDS) ≥10. Potential exposures were selected a priori and compared between patients with and without a positive postpartum depression screen using Wilcoxon rank-sum and Fisher's exact tests. Secondary outcomes were responses to a longitudinal follow-up survey sent to English-speaking patients evaluating cardiac status, mental health, and infant development.Results: Of 126 eligible cardiac patients, 23 (18.3%) had a positive postpartum depression screen. Patients with a positive postpartum depression screen were more likely to have had antepartum anticoagulation with heparin or enoxaparin (56.5% versus 26.2%, p=0.007), blood transfusion during delivery (8.7% versus 0%, p=0.032), and maternal-infant separation postpartum (52.2% versus 28.2%, p=0.047) compared to patients with a negative screen. Among 29 patients with a positive screen who responded to the follow up survey, 50% reported being formally diagnosed with anxiety or depression and 33.3% reported child development problems.Conclusions: Our results highlight the importance of screening for postpartum depression in patients with cardiac disease, especially those requiring antepartum anticoagulation or maternal-infant separation postpartum.

• Cellular aging and telomere dynamics in pregnancy. Current opinion in obstetrics & gynecology Panelli, D. M., Bianco, K. 2021

  Abstract

  PURPOSE OF REVIEW: Telomere biology is an emerging area of scientific interest. Telomeres are deoxynucleic acid caps at the ends of chromosomes that naturally shorten over one's lifespan; because of this, short telomeres have been studied as a marker of cellular aging. Given the association between short telomeres and genetic and environmental factors, their role in pregnancy has become an intriguing area of research.RECENT FINDINGS: This review describes recent data on telomeres in pregnancy. Specifically, we discuss the association between short maternal leukocyte telomeres and poor nutritional status, between short neonatal telomeres and greater maternal psychosocial stress, and between shorter fetal amniotic membrane telomeres and the spontaneous onset of parturition. We also review recent studies suggesting that events during pregnancy can impact telomeres in the offspring years into the future.SUMMARY: Telomere length varies in maternal, placental, and neonatal cells, but within each of these compartments telomeres may play their own distinct role during pregnancy. Whether telomeres are reflective of the cumulative impact of stressors, or part of an as-yet unknown fetal programming mechanism is an area of interest. With future research, we may work toward a better understanding of gestational biology which could have far reaching intergenerational impacts.

• Association of Epilepsy and Severe Maternal Morbidity. Obstetrics and gynecology Panelli, D. M., Leonard, S. A., Kan, P., Meador, K. J., McElrath, T. F., Darmawan, K. F., Carmichael, S. L., Lyell, D. J., El-Sayed, Y. Y., Druzin, M. L., Herrero, T. C. 2021

  Abstract

  OBJECTIVE: To evaluate severe maternal morbidity (SMM) among patients with epilepsy and patients without epilepsy.METHODS: We retrospectively examined SMM using linked birth certificate and maternal hospital discharge records in California between 2007 and 2012. Epilepsy present at delivery admission was the exposure and was subtyped into generalized, focal and other less specified, or unspecified. The outcomes were SMM and nontransfusion SMM from delivery up to 42 days' postpartum, identified using Centers for Disease Control and Prevention indicators. Multivariable logistic regression models were used to adjust for confounders, which were selected a priori. We also estimated the association between epilepsy and SMM independent of comorbidities by using a validated obstetric comorbidity score. Severe maternal morbidity indicators were then compared using the same multivariable logistic regression models.RESULTS: Of 2,668,442 births, 8,145 (0.3%) were to patients with epilepsy; 637 (7.8%) had generalized, 6,250 (76.7%) had focal or other less specified, and 1,258 (15.4%) had unspecified subtypes. Compared with patients without epilepsy, patients with epilepsy had greater odds of SMM (4.3% vs 1.4%, adjusted odds ratio [aOR] 2.91, 95% CI 2.61-3.24) and nontransfusion SMM (2.9% vs 0.7%, aOR 4.16, 95% CI 3.65-4.75). Epilepsy remained significantly associated with increased SMM and nontransfusion SMM after additional adjustment for the obstetric comorbidity score, though the effects were attenuated. When grouped by organ system, all SMM indicators were significantly more common among patients with epilepsy-most notably those related to hemorrhage and transfusion.CONCLUSION: Severe maternal morbidity was significantly increased in patients with epilepsy, and SMM indicators across all organ systems contributed to this.

• Postpartum Transition of Care: Racial/Ethnic Gaps in Veterans' Re-Engagement in VA Primary Care after Pregnancy. Women's health issues : official publication of the Jacobs Institute of Women's Health Shankar, M., Chan, C. S., Frayne, S. M., Panelli, D. M., Phibbs, C. S., Shaw, J. G. 2021

  Abstract

  INTRODUCTION: Pregnancy presents an opportunity to engage veterans in health care. Guidelines recommend primary care follow-up in the year postpartum, but loss to follow-up is common, poorly quantified, and especially important for those with gestational diabetes (GDM) and hypertension. Racial maternal inequities are well-documented and might be exacerbated by differential postpartum care. This study explores variation in postpartum re-engagement in U.S. Department of Veteran Affairs health care system (VA) primary care to identify potential racial/ethnic inequities in this care transition.METHODS: We conducted a complete case analysis of the 2005-2014 national VA birth cohort (n=18,414), and subcohorts of veterans with GDM (n=1,253), and hypertensive disorders of pregnancy (HDP; n=2,052) using VA-reimbursed discharge claims and outpatient data. Outcomes included incidence of any VA primary care visit in the postpartum year; in age-adjusted logistic regression, we explored race/ethnicity as a primary predictor.RESULTS: In the year after a VA-covered birth, the proportion of veterans with one or more primary care visit was 53.8% overall, and slightly higher in the GDM (56.0%) and HDP (57.4%) subcohorts. In adjusted models, the odds of VA primary care follow-up were significantly lower for Black/African American (odds ratio, 0.87; 95% confidence interval, 0.81-0.93), Asian (odds ratio, 0.76; 95% confidence interval, 0.61-0.95), and Hawaiian/other Pacific Islander (odds ratio, 0.73; 95% confidence interval, 0.55-0.96) veterans, compared with White veterans. Among the subcohorts with GDM or HDP, there were no significant associations between primary care and race/ethnicity.CONCLUSIONS: One-half of veterans re-engage in VA primary care after childbirth, with significant racial differences in this care transition. Re-engagement for those with the common pregnancy complications of HDP and GDM is only slightly higher, and less than 60%. The potential for innovations like VA maternity care coordinators to address such gaps merits attention.

  Abstract

  Operative vaginal delivery (OVD) is a critical tool in reducing primary cesarean birth, but declining OVD rates and concerns about provider skill necessitate a clear understanding of risks. These risks are ambiguous because most studies compare outcomes with OVD to spontaneous vaginal delivery, rather than to second stage cesarean which is usually the realistic alternative.Our objective was to compare severe maternal and neonatal morbidity by mode of delivery among patients with a prolonged second stage of labor who had a successful OVD, a cesarean birth after failed OVD, or a cesarean birth without an OVD attempt.We used a population-based database to evaluate nulliparous, term, singleton, vertex livebirths in California between 2007 and 2012 among patients with a prolonged second stage of labor. Birth certificate and ICD-9-CM coded diagnoses and procedures were used for ascertainment of exposure, outcome, and demographics. Exposure was mode of delivery among patients who had any OVD attempt versus cesarean without OVD attempt. The outcomes were severe maternal morbidity (SMM) and severe unexpected newborn morbidity (UNM), defined using established indices. Anticipating that the code for prolonged second stage of labor would represent only a fraction of true OVD candidates, a secondary analysis was conducted removing this restriction in order to explore granular outcomes in a larger cohort with unsuccessful labor. Multivariable logistic regression was used to compare outcomes by mode of delivery adjusted for measured confounders. Sensitivity analyses were done excluding patients with combined vacuum-forceps and birthweight >4000g.9,239 prolonged second stage births were included; 6,851 (74.1%) were successful OVDs, 301 (3.3%) were failed OVDs, and 2,087 (22.6%) were cesareans without OVD attempts. Of successful OVDs, 6,195 (90.4%) were vacuums and 656 (10.6%) were forceps. Of failed OVDs where OVD type was specified, 83 (47.4%) were vacuums, 38 (21.7%) were forceps, and 54 (30.9%) were combined vacuum-forceps. Of note, all 54 combined vacuum-forceps OVD attempts that we identified failed. Patients with failed OVD differed from those with successful OVD, with higher rates of comorbidities, use of combined OVD, and birthweight >4000 g. Successful OVD was associated with reduced SMM (aOR 0.55, 95% CI 0.39-0.78) without a difference in severe UNM (aOR 0.99, 95% CI 0.78-1.26). In contrast, failed OVD was associated with increased SMM (aOR 2.14, 95% CI 1.20-3.82) and severe UNM (aOR 1.78, 95% CI 1.09-2.86). Findings were similar in secondary analysis of 260,585 patients with unsuccessful labor.In this large cohort of nulliparous, term, singleton, vertex births, successful OVD was associated with a 45% reduction in SMM without differences in severe UNM when compared to cesarean birth after prolonged second stage of labor. OVD failed infrequently, but when it did it was associated with a 214% increase in SMM and a 78% increase in severe UNM; combined OVDs were major contributors to this, since all combined OVDs failed. Optimization of OVD success rates through means such as improved patient selection, enhanced provider skill, and dissuasion against combined OVD could reduce maternal and neonatal complications.

  Abstract

   To evaluate whether cervical dilation predicts the timing and likelihood of spontaneous labor at term. This was a retrospective cohort of nulliparous women with singleton pregnancies who delivered at term from 2013 to 2015. Outpatient cervical examinations performed after 37 weeks and prior to labor onset were collected. Survival analysis was used to analyze time to spontaneous labor with cervical dilation as the primary predictor, modeled as continuous and categorical variables (<1 cm, 1 cm, >1 cm). Our cohort included 726 women; 407 (56%) spontaneously labored, 263 (36%) were induced, and 56 (8%) had an unlabored cesarean delivery. Women with >1-cm dilation were three times more likely to spontaneously labor (adjusted hazard ratio [aHR]: 3.1; 95% confidence interval [CI]: 2.4-4) than those with <1-cm dilation. At 39 weeks, 60% of women with >1-cm dilation went into spontaneous labor as compared with only 28% of those with <1-cm dilation (aHR: 2.9; 95% CI: 2-4.4). In our cohort of nulliparous women at term, those with cervical dilation > 1 cm were significantly more likely to go into labor in the following week. This information can aid in counseling about elective induction of labor.

• Contraceptive utilization and counseling among breast cancer survivors. Journal of cancer survivorship : research and practice Mody, S. K., Gorman, J. R., Oakley, L. P., Layton, T. n., Parker, B. A., Panelli, D. n. 2019

  Abstract

  To explore contraceptive counseling and utilization among breast cancer survivors.We enrolled reproductive-aged women with a history of breast cancer for a cross-sectional study. Participants were recruited via the Athena Breast Health Network and via the Young Survival Coalition's social media postings. Descriptive statistics were calculated to understand utilization of and feelings about contraceptive methods before, during, and after breast cancer treatment.Data presented here are from an online survey of 150 breast cancer survivors who completed the survey. Seventy-one percent (n = 105) of respondents reported being sexually active and not pregnant during their primary cancer treatment (surgery, chemotherapy, and/or radiation). Of these, 90% (n = 94) reported using any form of contraceptive, and the most common method was condoms (n = 55, 52%). Respondents reported that safety concerns had the biggest influence on their contraception method choice. Sixty-one percent (n = 92) reported receiving contraceptive counseling by their oncologist either before or after treatment; however, 49% (n = 45) of those did not receive a specific recommendation for a contraceptive method. Of respondents who reported receiving contraceptive counseling from their gynecologist, 44% (n = 35) reported that their gynecologist specifically recommended a copper intrauterine device (IUD). The majority of respondents (n = 76, 52%) wanted their oncologist to discuss contraceptive options with them and preferred to receive this counseling at the time of diagnosis (n = 81, 57%).Breast cancer survivors in this study remained sexually active across the cancer care continuum and predominantly used condoms as their contraceptive method during treatment. Breast cancer patients would prefer contraceptive counseling from their oncologist at the time of their cancer diagnosis.Education efforts in the future should focus on initiatives to improve comprehensive contraceptive counseling at the time of diagnosis by an oncologist.

• Evaluation of a Quality Improvement Intervention to Increase Vaginal Birth for Twins. Obstetrics and gynecology Easter, S. R., Bibbo, C., Panelli, D., Little, S. E., Carusi, D., Robinson, J. N. 2018; 132 (1): 85-93

  Abstract

  To evaluate whether there was an association between the systematic promotion of twin vaginal delivery and an increase in the rates of twin vaginal birth.We conducted a retrospective cohort study. We implemented a quality improvement initiative promoting twin vaginal delivery at an academic tertiary care center in 2013. The program included a needs assessment, simulation of vaginal twin delivery, online educational material, and the expansion of a dedicated twin clinic. We analyzed rates of twin vaginal birth in pregnancies at or beyond 24 weeks of gestation without a contraindication to labor, prior uterine surgery, or a demise or lethal anomaly of either twin. Using linear regression, we calculated annual adjusted rates of twin vaginal birth from 2010 to 2015 and in the 3 years before and after our intervention. We performed an interrupted time-series analysis estimating rates of change before and after the intervention to account for the influence of secular trend.Of 1,574 patients delivering twins, 897 (57%) were included, with 479 in the 3 years before and 418 in the 3 years after the intervention. Adjusted rates of vaginal delivery increased from 32.1% (n=153) to 44.2% (n=185) before and after the intervention (P<.01), with a decrease in elective cesarean delivery from 54.6% (n=479) to 44.3% (n=185) (P<.01). Rates of breech extraction increased after the intervention (5.7% vs 9.3%, P=.04). However, there was no difference in the rate of change in twin vaginal birth in the time period before (1.35% annual increase, P=.76) or after (5.8% annual increase, P=.40) the intervention.Although we observed an increased rate of twin vaginal birth in the time period after our intervention, because the rates of increase before and after the intervention were not statistically different, the increase is not attributable to our intervention and is more properly attributed to secular trend.

• Clinical Factors Associated With Presentation Change of the Second Twin After Vaginal Delivery of the First Twin. Obstetrics and gynecology Panelli, D. M., Easter, S. R., Bibbo, C., Robinson, J. N., Carusi, D. A. 2017; 130 (5): 1104-1111

  Abstract

  To identify clinical factors associated with a change from vertex to nonvertex presentation in the second twin after vaginal birth of the first.We assembled a retrospective cohort of women with viable vertex-vertex twin pregnancies who delivered the presenting twin vaginally. Women whose second twin changed from vertex to nonvertex after vaginal birth of the first were classified as experiencing an intrapartum change in presentation. Characteristics associated with intrapartum presentation change in a univariate analysis with a P value ≤.10 were then evaluated in a multivariate logistic regression model.Four-hundred fifty women met inclusion criteria, of whom 55 (12%) had intrapartum presentation change of the second twin. Women experiencing intrapartum presentation change were more likely to be multiparous (69% compared with 47%, P<.01) and to have had a change in the presentation of the second twin between the most recent antepartum ultrasonogram and the ultrasonogram done on admission to labor and delivery (11% compared with 4%, P=.04). In an adjusted analysis, multiparity and gestational age less than 34 weeks were significantly associated with presentation change (adjusted odds ratio [OR] 2.9, 95% CI 1.5-5.6 and adjusted OR 2.6, 95% CI 1.1-5.9, respectively). Women with intrapartum presentation change were more likely to undergo cesarean delivery for their second twin (44% compared with 7%, P<.01) with an adjusted OR of 10.50 (95% CI 5.20-21.20) compared with those with stable intrapartum presentation. Twenty of the 24 (83%) cesarean deliveries performed in the intrapartum presentation change group were done for issues related to malpresentation.Multiparity and gestational age less than 34 weeks are associated with intrapartum presentation change of the second twin.

• Incidence, diagnosis and management of tubal and nontubal ectopic pregnancies: a review. Fertility research and practice Panelli, D. M., Phillips, C. H., Brady, P. C. 2015; 1: 15

  Abstract

  Ectopic pregnancy is a potentially life-threatening condition occurring in 1-2 % of all pregnancies. The most common ectopic implantation site is the fallopian tube, though 10 % of ectopic pregnancies implant in the cervix, ovary, myometrium, interstitial portion of the fallopian tube, abdominal cavity or within a cesarean section scar.Diagnosis involves a combination of clinical symptoms, serology, and ultrasound. Medical management is a safe and effective option in most clinically stable patients. Patients who have failed medical management, are ineligible, or present with ruptured ectopic pregnancy or heterotopic pregnancy are most often managed with excision by laparoscopy or, less commonly, laparotomy. Management of nontubal ectopic pregnancies may involve medical or surgical treatment, or a combination, as dictated by ectopic pregnancy location and the patient's clinical stability. Following tubal ectopic pregnancy, the rate of subsequent intrauterine pregnancy is high and independent of treatment modality.This review describes the incidence, risk factors, diagnosis, and management of tubal and non-tubal ectopic and heterotopic pregnancies, and reviews the existing data regarding recurrence and future fertility.
