Cigarette smoking in opioid-dependent pregnant women: neonatal and maternal outcomes.

ABSTRACT: The relationship between cigarette smoking and neonatal and maternal clinical outcomes among opioid-agonist-treated pregnant patients is sparse.(1) Is smoking measured at study entry related to neonatal and maternal outcomes in pregnant women receiving opioid-agonist medication? (2) Is it more informative to use a multi-item measure of smoking dependence or a single-item measure of daily smoking? (3) Is the relationship between smoking at study entry and outcomes different between methadone and buprenorphine?Secondary analyses examined the ability of the tobacco dependence screener (TDS) and self-reported past 30-day daily average number of cigarettes smoked, both measured at study entry, to predict 12 neonatal and 9 maternal outcomes in 131 opioid-agonist-maintained pregnant participants.Past 30-day daily average number of cigarettes smoked was significantly positively associated with total amount of morphine (mg) needed to treat neonatal abstinence syndrome (NAS), Adjusted Odds Ratio (AOR)=1.06 (95% CI: 1.02, 1.09), number of days medicated for NAS, AOR=1.04 (95% CI: 1.01, 1.06), neonatal length of hospital stay in days, AOR=1.03 (95% CI: 1.01, 1.05), and negatively associated with 1-AOR=.995 (95% CI: .991,.999) and 5-min Apgar scores, AOR=.996 (95% CI: .994,.998). Simple effect tests of the two significant TDS×medication condition effects found TDS was unrelated to non-normal presentation and amount of voucher money earned in the methadone [AORs=.90 (95% CI: .74, 1.08, p>.24) and 1.0 (95% CI: .97, 1.03, p>.9)] but significant in the buprenorphine condition [AORs=1.57 (95% CI: 1.01, 2.45, p<.05) and 1.08 (95% CI: 1.04, 1.12, p<.01)].Regardless of prenatal methadone or buprenorphine exposure, heavier cigarette smoking was associated with more compromised birth outcomes.

Project description:Background Pregnant women with underlying heart disease ( HD ) are at increased risk for adverse maternal, obstetric, and neonatal outcomes. Methods and Results Inpatient maternal delivery admissions and linked neonatal stays for women with cardiomyopathy, adult congenital HD, pulmonary hypertension ( PH ), and valvular HD were explored utilizing the Statewide Planning and Research Cooperative System (New York), January 1, 2000, through December 31, 2014, with the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Maternal major adverse cardiac events, neonatal adverse clinical events ( NACE ), and obstetric complications were recorded. Outcomes were compared using multiple logistic regression modeling. Among 2 284 044 delivery admissions, 3871 women had HD ; 676 (17%) had cardiomyopathy, 1528 (40%) had valvular HD, 1367 (35%) had adult congenital HD, and 300 (8%) had PH . Major adverse cardiac events occurred in 16.1% of women with HD , with most in the cardiomyopathy (45.9%) and PH (25%) groups. NACE was more common in offspring of women with HD (18.4% versus 7.1%), with most in the cardiomyopathy (30.0%) and PH (25.0%) groups. Increased risk of NACE was noted for women with HD (odds ratio [ OR ]: 2.8; 95% confidence interval [ CI ], 2.5-3.0), with the highest risk for those with cardiomyopathy ( OR : 5.9; 95% CI , 5.0-7.0) and PH ( OR : 4.5; 95% CI , 3.4-5.9). Preeclampsia ( OR : 5.1; 95% CI , 3.0-8.6), major adverse cardiac events ( OR : 2.3; 95% CI , 1.8-2.9), preexisting diabetes mellitus ( OR : 4.3; 95% CI , 1.5-12.3), and obstetric complications ( OR : 2.9; 95% CI , 1.7-5.2) were independently associated with higher NACE risk. Conclusions Neonatal complications were higher in offspring of pregnant women with HD , particularly cardiomyopathy and PH . Preeclampsia, major adverse cardiac events, obstetric complications, and preexisting diabetes mellitus were independently associated with a higher risk of NACE .

Project description:ImportanceWomen with disabilities have a higher risk of preterm birth, gestational diabetes, preeclampsia, and cesarean delivery; however, their risk of other obstetric interventions, adverse maternal outcomes, and clinical indications for increased cesarean delivery is unclear.ObjectiveTo evaluate risk of a range of obstetric interventions and adverse maternal outcomes, including severe maternal morbidities (SMM) and mortality, among women with and without disabilities.Design, setting, and participantsThe Consortium on Safe Labor was a retrospective cohort that included comprehensive medical chart review for deliveries between January 2002 and January 2008. Data were collected from 12 clinical sites, which included 19 hospitals across the United States. This secondary analysis was conducted in February to July 2021.ExposuresUsing International Classification of Diseases, Ninth Revision, codes and a validated algorithm to define disability, participants were classified as having physical, intellectual, sensory, or any disability, and compared with women with no documented disability.Main outcomes and measuresThe relative risk (RR) of 23 obstetric interventions and adverse maternal outcomes, including SMM and mortality, was evaluated.ResultsOf the 223 385 women in the study, 9206 (4.1%) were Asian or Pacific Islander, 50 235 (22.5%) were Black, 39 039 (17.5%) were Hispanic, and 110 443 (49.4%) were White, with a mean (SD) age of 27.6 (6.2) years. There were 2074 (0.9%) women with disability and 221 311 (99.1%) without. Among women with disabilities, 1733 (83.5%) were physical, 91 (4.4%) were intellectual, and 250 (12.1%) were sensory. Compared with women with no disability, women with disabilities had higher risk of gestational diabetes, placenta previa, premature rupture of membranes, preterm premature rupture of membranes, and postpartum fever as well as maternal death (adjusted relative risk [aRR], 11.19; 95% CI, 2.40-52.19) and individual SMMs: severe preeclampsia/eclampsia (aRR, 2.15; 95% CI, 1.80-2.56), hemorrhage (aRR, 1.27; 95% CI, 1.09-1.49), and fever (aRR, 1.32; 95% CI, 1.03-1.67), with the highest risk observed for thromboembolism (aRR, 6.08; 95% CI, 4.03-9.16), cardiovascular events (aRR, 4.02; 95% CI, 2.87-5.63), and infection (aRR, 2.69; 95% CI, 1.97-3.67). Women with any disability also had higher risk of interventions, including oxytocin augmentation, operative vaginal delivery, and cesarean delivery (aRR, 1.33; 95% CI, 1.25-1.42), with the cesarean indication less likely to be medically indicated (aRR, 0.79; 95% CI, 0.70-0.89). Risk of adverse outcomes and interventions remained consistent across disability categories.Conclusions and relevanceIn this study, women with physical, intellectual, and sensory disability during pregnancy were at higher risk of adverse outcomes, including a broad range of SMM and maternal mortality.

Project description:Background: While the relationship between hemoglobin (Hb) concentrations and pregnancy outcomes has been studied often, most reports have focused on a specific Hb cutoff used to define anemia. Fewer studies have evaluated pregnancy outcomes across the entire range of Hb values. Moreover, to date, most studies of the relationship of Hb concentrations to pregnancy outcomes have been done in high-income countries. Thus, we have sought to determine the relationship between the range of maternal Hb concentrations and adverse birth outcomes among South Asian pregnant women.Methods: For this study, we used data collected from two South Asian countries (Pakistan - Sindh Province and two sites in India - Belagavi and Nagpur) in a prospective maternal and newborn health registry study. To assess the association between Hb concentrations and various maternal and fetal outcomes, we classified the Hb concentrations into seven categories. Regression analyses adjusting for multiple potential confounders were performed to assess adverse pregnancy outcomes across the range of Hb concentrations.Findings: Between January 2012 and December 2018, 130,888 pregnant women were enrolled in the South Asian sites had a Hb measurement available, delivered and were included in the analyses. Overall, the mean Hb concentration of pregnant women from the sites was 9.9?g/dL, 10.0?g/dL in the Indian sites and 9.5?g/dL in the Pakistan site. Hb concentrations <?7?g/dL were observed in 6.9% of the pregnant Pakistani women and 0.2% of the Indian women. In both the Pakistani and Indian sites, women with higher parity and women with no formal education had lower Hb concentrations. In the Pakistani site, women >?35?years of age, women with ?4 children and those who enrolled in the third trimester were more likely to have Hb concentrations of <?7?g/dL but these associations were not found for the Indian sites. When adjusting for potential confounders, for both India and Pakistan, lower Hb concentrations were associated with stillbirth, preterm birth, lower mean birthweight, and increased risk of low birthweight. In the Pakistani site, there was evidence of a U-shaped relationship between Hb concentrations and low birth weight, and neonatal mortality, and in India with hypertensive disease.Interpretation: This study documented the relationship between maternal Hb concentrations and adverse pregnancy outcomes in women from the Pakistani and Indian sites across the range of Hb values. Both low and high Hb concentrations were associated with risk of at least some adverse outcomes. Hence, both low and high values of Hb should be considered risk factors for the mother and fetus.
