[PMID: 37939985 DOI: 10.1016/j.ajog.2023.11.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 11/01/2023] [Accepted: 11/02/2023] [Indexed: 11/10/2023]
Abstract
BACKGROUND Second-trimester abortion may result in a live birth, but the extent to which this outcome occurs is unknown. OBJECTIVE This study aimed to examine rates of live birth after pregnancy termination in the second trimester and identify associated risk factors. STUDY DESIGN We conducted a retrospective cohort study of 13,777 second-trimester abortions occurring in hospital settings between April 1, 1989 and March 31, 2021 in Quebec, Canada. The exposure was induced abortion between 15 and 29 weeks of gestation, including the indication for (fetal anomaly, maternal emergency, other) and use of feticidal injection (intracardiac/intrathoracic or intraamniotic). The primary outcome was live birth following abortion. We measured the rate of live birth per 100 abortions and used adjusted log-binomial regression models to estimate risk ratios and 95% confidence intervals for the association of fetal and maternal characteristics with the risk of live birth. We assessed the extent to which feticidal injection reduced the risk. RESULTS Among 13,777 abortions between 15 and 29 weeks of gestation, 1541 (11.2%) led to live birth. Fetal anomaly was a common indication for termination (48.1%), and most abortions were by labor induction (72.2%). Compared with abortion between 15 and 19 weeks, abortion between 20 and 24 weeks was associated with 4.80 times the risk of live birth (95% confidence interval, 4.20-5.48), whereas abortion between 25 and 29 weeks was associated with 1.34 times the risk (95% confidence interval, 1.00-1.79). Feticidal injection reduced the risk of live birth by 57% compared with no injection (risk ratio, 0.43; 95% confidence interval, 0.36-0.51). Intracardiac or intrathoracic injection was particularly effective at preventing live birth (risk ratio, 0.02; 95% confidence interval, 0.01-0.07). CONCLUSION Second-trimester abortion carries a risk of live birth, especially at 20 to 24 weeks of gestation, although feticidal injection may protect against this outcome.

Abstract
OBJECTIVES To compare two prostaglandin analogs and two application intervals between mifepristone and the prostaglandin analog administration on the time to abortion in second trimester termination of pregnancy. Other endpoints were live birth rate and fetal lifetime after expulsion. METHODS Retrospective data of 373 abortions performed were evaluated. Four medical induction subgroups and two feticide subgroups were considered. The definition criteria of the subgroups were the choice of administered prostaglandin analog (misoprostol vs. sulprostone) and the time interval between mifepristone and prostaglandin analog administration (48 vs. 24 h). The outcome parameters were the time to complete uterine evacuation (TCUE), the live birth rate and duration of fetal life. RESULTS In the misoprostol subgroups, the median TCUE was 1.6 h longer in the 24-h group than in the 48-h group (p=0.950). In the sulprostone subgroups, the median TCUE was 1.9 h shorter in the 24-h group than in the 48-h group (p=0.950). The median TCUE was shorter for sulprostone than for misoprostol in all six subgroups (p<0.001). The rate of fetal live births ranged between 13.6 and 15.9% within the medical induction subgroups (p=0.969). The median fetal lifetime was slightly shorter in the sulprostone groups than in the misoprostol groups (p=0.563). CONCLUSIONS Both application intervals and prostaglandin analogs are similarly effective. The therapy regime should be adapted to the personal preferences of the woman, the situational and clinical conditions.

Abstract
OBJECTIVE Little is known on the long-term risk of mortality following pregnancy loss. We assessed risks of premature mortality up to three decades after miscarriage, induced abortion, ectopic or molar pregnancy, and stillbirth relative to live birth. STUDY DESIGN We carried out a longitudinal cohort study of 1,293,640 pregnant women with 18,896,737 person-years of follow-up in Quebec, Canada, from 1989 to 2018. We followed the women up to 29 years after their last pregnancy event to determine the time and cause of future in-hospital deaths before age 75 years. We used adjusted Cox regression models to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association of miscarriage, induced abortion, ectopic pregnancy, molar pregnancy, and stillbirth with premature mortality, compared with live birth. RESULTS Premature mortality rates were higher for most types of pregnancy loss than live birth. Compared with live birth, pregnancy loss was associated with an elevated risk of premature mortality (HRmiscarriage 1.48, 95% CI 1.33, 1.65; HRinduced abortion 1.50, 95% CI 1.39, 1.62; HRectopic 1.55, 95% CI 1.35, 1.79; and HRstillbirth 1.68, 95%. CI 1.17, 2.41). Molar pregnancy was not associated with premature mortality (HR 0.87, 95% CI 0.33, 2.32). Miscarriage and induced abortion were associated with most causes of death, whereas ectopic pregnancy was associated with cardiovascular (HR 2.18, 95 % CI 1.39, 3.42), cancer (HR 1.38, 95 % CI 1.11, 1.73), and suicide-related mortality (HR 4.94, 95 % CI 2.29, 10.68). Stillbirth was associated with cardiovascular mortality (HR 4.91, 95 % CI 2.33, 10.36). CONCLUSION Pregnancy loss is associated with an elevated risk of premature mortality up to three decades later, particularly cardiovascular, cancer, and suicide-related deaths.

Abstract
BACKGROUND A country's abortion law is a key component in determining the enabling environment for safe abortion. While restrictive abortion laws still prevail in most low- and middle-income countries (LMICs), many countries have reformed their abortion laws, with the majority of them moving away from an absolute ban. However, the implications of these reforms on women's access to and use of health services, as well as their health outcomes, is uncertain. First, there are methodological challenges to the evaluation of abortion laws, since these changes are not exogenous. Second, extant evaluations may be limited in terms of their generalizability, given variation in reforms across the abortion legality spectrum and differences in levels of implementation and enforcement cross-nationally. This systematic review aims to address this gap. Our aim is to systematically collect, evaluate, and synthesize empirical research evidence concerning the impact of abortion law reforms on women's health services and outcomes in LMICs. METHODS We will conduct a systematic review of the peer-reviewed literature on changes in abortion laws and women's health services and outcomes in LMICs. We will search Medline, Embase, CINAHL, and Web of Science databases, as well as grey literature and reference lists of included studies for further relevant literature. As our goal is to draw inference on the impact of abortion law reforms, we will include quasi-experimental studies examining the impact of change in abortion laws on at least one of our outcomes of interest. We will assess the methodological quality of studies using the quasi-experimental study designs series checklist. Due to anticipated heterogeneity in policy changes, outcomes, and study designs, we will synthesize results through a narrative description. DISCUSSION This review will systematically appraise and synthesize the research evidence on the impact of abortion law reforms on women's health services and outcomes in LMICs. We will examine the effect of legislative reforms and investigate the conditions that might contribute to heterogeneous effects, including whether specific groups of women are differentially affected by abortion law reforms. We will discuss gaps and future directions for research. Findings from this review could provide evidence on emerging strategies to influence policy reforms, implement abortion services and scale up accessibility.

Abstract
OBJECTIVE To evaluate the rate of live birth and the duration of survival after termination of pregnancy without feticide. METHODS We conducted a retrospective analysis of 241 terminations of pregnancy without feticide for fetal anomalies or genetic abnormalities between 20 0/7 and 24 0/7 weeks of gestation at a single tertiary care referral center in Europe between February 2003 and May 2017. A multivariate binary regression model was used to evaluate factors associated with live birth. RESULTS Pregnancies were terminated at a mean gestational age of 22.1±1.1 completed weeks of gestation. Median birth weight was 440 g (range 141-1,890 g). Live birth occurred in 122 cases (50.6%, 95% CI 44.4-56.8); median survival time was 32 minutes (range 1-267 minutes). Factors associated with live birth were gestational age at labor induction (odds ratio 1.41, 95% CI 1.01-2.01; P=.049) and fetal anomalies (P=.046). CONCLUSION After termination of pregnancy without feticide between 20 0/7 and 24 0/7 weeks of gestation, the live birth rate was 50.6% (95% CI 44.4-56.8). A lower gestational age at labor induction and the presence of skeletal, cerebral, renal, or multiple fetal anomalies increased the chance of stillbirth.

Language and infant mortality in a large Canadian province. Public Health 2016; 139:154-160. [PMID: 27393625 DOI: 10.1016/j.puhe.2016.06.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2015] [Revised: 04/14/2016] [Accepted: 06/10/2016] [Indexed: 11/22/2022]
Abstract
OBJECTIVES Infant mortality in minority populations of Canada is poorly understood, despite evidence of ethnic inequality in other countries. We studied infant mortality in different linguistic groups of Quebec, and assessed how language and deprivation impacted rates over time. STUDY DESIGN Population-level study of vital statistics data for 1,985,287 live births and 10,283 infant deaths reported in Quebec from 1989 through 2012. METHODS We computed infant mortality rates for French, English, and foreign languages according to level of material deprivation. Using Kitagawa's method, we evaluated the impact of changes in mortality rates, and population distribution of language groups, on infant mortality in the province. RESULTS Infant mortality declined from 6.05 to 4.61 per 1000 between 1989-1994 and 2007-2012. Most of the decline was driven by Francophones who contributed 1.39 fewer deaths per 1000 births over time, and Anglophones of wealthy and middle socio-economic status who contributed 0.13 fewer deaths per 1000 births. The foreign language population and poor Anglophones contributed more births over time, including 0.08 and 0.02 more deaths per 1000 births, respectively. Mortality decreased for Francophones and Anglophones in each level of deprivation. Rates were lower for foreign languages, but increased over time, especially for the poor. CONCLUSIONS Infant mortality rates decreased for Francophones and Anglophones in Quebec, but increased for foreign languages. Poor Anglophones and individuals of foreign languages contributed more births over time, and slowed the decrease in infant mortality. Language may be useful for identifying inequality in infant mortality in multicultural nations.
