IMPORTANCE/UNASSIGNED:Insomnia and obstructive sleep apnea (OSA) are associated with pregnancy complications. OBJECTIVE/UNASSIGNED:To evaluate the association of insomnia and OSA during pregnancy with the risk of ischemic placental disease (IPD) and severe morbidity (SM) and to compare these risks between the 2 sleep disorders. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This cross-sectional study included a statewide population-based sample of liveborn singleton births with linked birth certificates for birthing people and their infants in California from January 1, 2011, through December 31, 2020. The analysis was performed on July 22, 2024. EXPOSURES/UNASSIGNED:Insomnia and OSA. MAIN OUTCOMES AND MEASURES/UNASSIGNED:The main outcomes were IPD, defined as preeclampsia, placental abruption, and birth of a neonate small for gestational age (SGA), and SM, defined according to the Centers for Disease Control and Prevention definition. RESULTS/UNASSIGNED:During the study period, there were 4 145 096 singleton live births among birthing people aged 13 to 55 years; 4783 (0.1%) had insomnia, 5642 (0.1%) had OSA, and 4 134 671 (99.7%) had neither condition. The prevalence of insomnia and OSA was 116 and 136 cases per 1000 live births, respectively. Compared with patients without insomnia or OSA (738 660 [17.9%]), the adjusted relative risk (ARR) of any IPD was 1.42 (95% CI, 1.35-1.50) for those with insomnia (1406 patients [29.4%]) and 1.57 (95% CI, 1.50-1.64) for those with OSA (1848 [32.8%]). Compared with patients with neither disorder, the ARR of birth of an SGA neonate was higher for those with insomnia (1.23; 95% CI, 1.13-1.35) than for those with OSA. The ARR of preterm birth was 1.81 (95% CI, 1.68-1.95) for insomnia (711 patients [14.9%]) and 1.73 (95% CI, 1.62-1.85) for OSA (870 [15.4%]) vs neither disorder (279 364 [6.8%]). The ARR of SM was 2.26 (95% CI, 2.03-2.50) for insomnia (366 patients [7.7%]) and 2.81 (95% CI, 2.58-3.06) for OSA (545 [9.7%]) vs neither disorder (93 857 [2.3%]). CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this cross-sectional study of singleton live births, pregnant individuals with insomnia or OSA were at increased risk for IPD, SM, and preterm birth compared with those without these sleep disorders. Further study is needed to determine the biological mechanisms for these risks and whether early identification and targeted preventive interventions may improve pregnancy outcomes.

BACKGROUND AND OBJECTIVES/OBJECTIVE:Healthcare is increasingly being delivered in the outpatient setting, but robust quality improvement programs and performance metrics are lacking in ambulatory care, particularly specialty-based ambulatory care. METHODS:To promote quality improvement in ambulatory care, we developed an infrastructure to create specialty-specific quality measures and dashboards that could be used to display providers' performance across relevant measures to individual providers and institutional leaders. RESULTS:The products of this program include a governance and infrastructure for specialty-specific ambulatory quality metrics as well as two distinct dashboards for data display. One dashboard is provider-facing, displaying provider's performance on specialty-specific measures as compared to institutional standards. The second dashboard is a leadership dashboard that provides overall and provider-level information on performance across measures. CONCLUSIONS:The Specialty-based Ambulatory Quality program reflects a systematic, institutionally-supported quality improvement framework that can be applied across diverse ambulatory specialties. As next steps, we plan to evaluate the program's impact on provider performance across measures and expand this program to other specialties practicing in the outpatient setting.

OBJECTIVE:To investigate the relationship between platelet indices (count, size and production/immaturity) and hypertensive disorders of pregnancy. STUDY DESIGN/METHODS:This was a secondary analysis of a prospective cohort of pregnant individuals followed from first trimester through delivery at an academic tertiary care institution. Routine platelet indices obtained prospectively during prenatal care and delivery were compared between those who developed a hypertensive disorder of pregnancy and those who did not. We assessed platelet count (by trimester), mean platelet volume, and immature platelet fraction measured as percent (%) and absolute count. Data were analyzed using Fisher's Exact test, chi-square test, and multivariable logistic regression. P < 0.05 was considered statistically significant. RESULTS: = 0.01) compared to those without a hypertensive disorder of pregnancy, after adjusting for age, race/ethnicity, obesity, nulliparity, and chronic hypertension. The prevalence and likelihood of a hypertensive disorder of pregnancy increased with increasing mean platelet volume, as well as with both the percent and absolute immature platelet fraction. There was no difference between groups in platelet count in the first trimester, second trimester, or at delivery. CONCLUSIONS:An increase in platelet size and immaturity was observed in those with a hypertensive disorder of pregnancy. These data support further investigation of platelets in the mechanisms of the development of hypertensive disorders of pregnancy and the use of platelet indices to better identify high risk groups in pregnancy.

OBJECTIVE:Preterm induction of labor can be necessary for maternal and fetal wellbeing. Duration of cervical ripening balloon (CRB) use has been studied in only term inductions. Our study investigated duration of time in hours for CRB expulsion and vaginal delivery in preterm inductions of labor. METHODS:This was a single-institution retrospective cohort study of preterm (< 37 weeks) and term (≥ 37 weeks) inductions with CRB between 2010 and 2021. Cesarean deliveries were excluded. Primary outcome was insertion to expulsion time of CRB. Secondary outcomes included induction to delivery time, cervical dilation after expulsion, misoprostol, and Pitocin use. Institutional review board (IRB) approval was obtained prior to the study. RESULTS:Ninety-eight patients with vaginal delivery after preterm CRB use were identified and matched 1:1 on baseline characteristics (p > 0.05) to term patients with vaginal delivery after CRB use. Mean insertion to expulsion time was significantly shorter for term than preterm inductions (mean 7.2 ± 3.09 h versus 8.5 ± 3.38 h; p < 0.01). Mean induction to delivery time was significantly shorter for term than preterm inductions (18.4 ± 7.6 h versus 22.5 ± 9.01 h; p < 0.01). Increased use of misoprostol, Pitocin, and second CRB were noted among the preterm cohort. Among term patients, more CRB placement at start of induction and greater cervical dilation post-balloon were found in comparison to preterm patients. CONCLUSION/CONCLUSIONS:Among patients undergoing preterm induction, longer insertion to expulsion time of CRB, longer induction to delivery time, and increased interventions should be expected. Different standards for labor management should be considered for achieving vaginal delivery in preterm inductions.

BACKGROUND/UNASSIGNED:Coronary artery spasm is an established mechanism of myocardial infarction with non-obstructive coronary arteries (MINOCA). Various mechanisms have been proposed, ranging from vascular smooth muscle hyperreactivity to endothelial dysfunction, to autonomic nervous system dysregulation. CASE SUMMARY/UNASSIGNED:We report a case of a 37-year-old woman who presented with recurrent non-ST elevation myocardial infarction (NSTEMI), coinciding with her menstrual periods. Intracoronary acetylcholine provocation testing resulted in coronary spasm in the left anterior descending artery (LAD) that was relieved with nitroglycerine. Initiating calcium channel blockade and suppressing cyclical variation in sex hormones resulted in improvement of her symptoms and cessation of monthly NSTEMI events due to coronary spasm. DISCUSSION/UNASSIGNED:Initiating calcium channel blockade and suppressing cyclical variation in sex hormones resulted in improvement of her symptoms and cessation of monthly NSTEMI events due to coronary spasm. Catamenial coronary artery spasm is a rare, but clinically important, presentation of myocardial infarction with non-obstructive coronary arteries (MINOCA).

INTRODUCTION: Preterm induction of labor can be necessary for maternal and fetal wellbeing. Duration of cervical ripening balloon (CRB) use has been studied only in term inductions. Our study investigated duration of time for CRB expulsion and vaginal delivery in preterm inductions of labor.
METHOD(S): This was a single-institution retrospective cohort study of preterm (<37 weeks) and term (>=37 weeks) inductions with CRB between 2010 and 2021. Cesarean deliveries were excluded. Primary outcome was insertion to expulsion time (IET) of CRB. Secondary outcomes included induction to delivery time (IDT), cervical dilation after expulsion, and misoprostol and Pitocin use. Institutional review board approval was obtained prior to the study.
RESULT(S): A total of 98 patients with vaginal delivery after preterm CRB use were identified and matched 1:1 on baseline characteristics to patients with vaginal delivery after term CRB use. Mean IET was significantly shorter for term CRB than for preterm induction (mean 7.2+/-3.09 hours versus 8.5+/-3.38 hours; P=.004). Mean IDT was significantly shorter for term CRB than preterm CRB induction (18.4+/-7.6 hours versus 22.5+/-9.01 hours; P<.001). Increased use of misoprostol, Pitocin, and second CRB were noted among the preterm cohort compared to the term cohort. Among term patients, more CRB placement at start of induction and greater cervical dilation postballoon were found in comparison to preterm patients.
CONCLUSION(S): Among patients undergoing preterm induction, longer IET, longer IDT, and increased interventions should be expected. Different standards for labor management should be considered for achieving vaginal delivery in preterm inductions

OBJECTIVE:To evaluate whether initiation of an institutional policy of universal perinatal depression screening was associated with sustained increases in frequency in screening and of depression treatment subsequent to a positive screen. METHODS:This retrospective cohort study included women receiving prenatal care in outpatient offices at a single academic medical center from 2008 to 2015. In 2009, an institutional policy of universal perinatal depression screening was disseminated in which screening twice antenatally and again postpartum were recommended. The frequency of screen completion at each recommended time point was compared between the prepolicy and postpolicy cohorts. A test of trend that assessed the frequency of screening each year after policy initiation was used to assess changes over time. The frequency with which care plans were created for women who screened positive for perinatal depression were compared before and after implementation. RESULTS:Of the 5,127 women who met inclusion criteria, 4,005 (78%) were in the postpolicy cohort. The frequency of completion of depression screening at the first prenatal visit (0.1% vs 65.5%), in the third trimester (0.0% vs 42.7%), and at the postpartum visit (69.5% vs 90.0%) increased after initiation of the policy (P<.001 for all). The improvement in postpartum depression screening completion persisted after controlling for potential confounders (adjusted odds ratio 5.3, 95% CI 4.4-6.5). After the initial increase in uptake of screening, the frequency of screening at the first and third trimester prenatal visits continued to increase over time (P<.001 for each), although this frequency remained stable for the postpartum visit (P=.29). Women with a positive postpartum depression screen were more likely to have depression treatment recommended or provided by their obstetrician postpolicy (64.7% vs 30.1%, P<.001). CONCLUSION:Implementation of an institutional policy of universal perinatal depression screening was associated with improvements in perinatal depression screening with concomitant improvements in depression treatment recommendations for women with a positive postpartum depression screen.
