Project description:ImportanceTexas' 2021 ban on abortion in early pregnancy may demonstrate how patterns of abortion might change following the US Supreme Court's June 2022 decision overturning Roe v Wade.ObjectiveTo assess changes in the number of abortions and changes in the percentage of out-of-state abortions among Texas residents performed at 12 or more weeks of gestation in the first 6 months following implementation of Texas Senate Bill 8 (SB 8), which prohibited abortions after detection of embryonic cardiac activity.Design, setting, and participantsRetrospective study of a sample of 50 Texas and out-of-state abortion facilities using an interrupted time series analysis to assess changes in the number of abortions, and Poisson regression to assess changes in abortions at 12 or more weeks of gestation. Data included 68 820 Texas facility-based abortions and 11 287 out-of-state abortions among Texas residents during the study period from September 1, 2020, to February 28, 2022.ExposuresAbortion care obtained after (September 2021-February 2022) vs before (September 2020-August 2021) implementation of SB 8.Main outcomes and measuresPrimary outcomes were changes in the number of facility-based abortions for Texas residents, in Texas and out of state, in the month after implementation of SB 8 compared with the month before. The secondary outcome was the change in the percentage of out-of-state abortions among Texas residents obtained at 12 or more weeks of gestation during the 6-month period after the law's implementation.ResultsBetween September 2020 and August 2021, there were 55 018 abortions in Texas and 2547 out-of-state abortions among Texas residents. During the 6 months after SB 8, there were 13 802 abortions in Texas and 8740 out-of-state abortions among Texas residents. Compared with the month before implementation of SB 8, the number of Texas facility-based abortions significantly decreased from 5451 to 2169 (difference, -3282 [95% CI, -3171 to -3396]; incidence rate ratio [IRR], 0.43 [95% CI, 0.36-0.51]) in the month after SB 8 was implemented. The number of out-of-state abortions among Texas residents significantly increased from 222 to 1332 (difference, 1110 [95% CI, 1047-1177]; IRR, 5.38 [95% CI, 4.19-6.91]). Overall, the total documented number of Texas facility-based and out-of-state abortions among Texas residents significantly decreased from 5673 to 3501 (absolute change, -2172 [95% CI, -2083 to -2265]; IRR, 0.67 [95% CI, 0.56-0.79]) in the first month after SB 8 was implemented compared with the previous month. Out-of-state abortions among Texas residents obtained at 12 or more weeks of gestation increased from 17.1% (221/1291) to 31.0% (399/1289) (difference, 178 [95% CI, 153-206]) during the period between September 2021 and February 2022 (P < .001 for trend).Conclusions and relevanceAmong a sample of abortion facilities, the 2021 Texas law banning abortion in early pregnancy (SB 8) was significantly associated with a decrease in the documented total of facility-based abortions in Texas and obtained by Texas residents in surrounding states in the first month after implementation compared with the previous month. Over the 6 months following SB 8 implementation, the percentage of out-of-state abortions among Texas residents obtained at 12 or more weeks of gestation significantly increased.

Project description:BackgroundIreland introduced a comprehensive workplace smoke-free legislation in March, 2004. Smoking-related adverse birth outcomes have both health care and societal cost implications. The main aim of this study was to determine the impact of the Irish smoke-free legislation on small-for-gestationa- age (SGA) births.Methods and findingsWe developed a population-based birthweight (BW) percentile curve based on a recent study to compute SGA (BW <5(th) percentile) and very SGA (vSGA - BW<3(rd) percentile) for each gestational week. Monthly births born between January 1999 and December 2008 were analyzed linking with monthly maternal smoking rates from a large referral maternity university hospital. We ran individual control and CUSUM charts, with bootstrap simulations, to pinpoint the breakpoint for the impact of ban implementation ( = April 2004). Monthly SGA rates (%) before and after April 2004 was considered pre and post ban period births, respectively. Autocorrelation was tested using Durbin Watson (DW) statistic. Mixed models using a random intercept and a fixed effect were employed using SAS (v 9.2). A total of 588,997 singleton live-births born between January 1999 and December 2008 were analyzed. vSGA and SGA monthly rates declined from an average of 4.7% to 4.3% and from 6.9% to 6.6% before and after April 2004, respectively. No auto-correlation was detected (DW = ~2). Adjusted mixed models indicated a significant decline in both vSGA and SGA rates immediately after the ban [(-5.3%; 95% CI -5.43% to -5.17%, p<0.0001) and (-0.45%; 95% CI: -0.7% to -0.19%, p<0.0007)], respectively. Significant gradual effects continued post the ban periods for vSGA and SGA rates, namely, -0.6% (p<0.0001) and -0.02% (p<0.0001), respectively.ConclusionsA significant reduction in small-for-gestational birth rates both immediately and sustained over the post-ban period, reinforces the mounting evidence of the positive health effect of a successful comprehensive smoke-free legislation in a vulnerable population group as pregnant women.

Project description:ObjectivesWe provide a methodology for estimating counts of single-year-of-age live-births, fetal-losses, abortions, and pregnant women from aggregated age-group counts. As a case study, we estimate counts for the 254 counties of Texas for the year 2010.ResultsWe use interpolation to estimate counts of live-births, fetal-losses, and abortions by women of each single-year-of-age for all Texas counties. We then use these counts to estimate the numbers of pregnant women for each single-year-of-age, which were previously available only in aggregate. To support public health policy and planning, we provide single-year-of-age estimates of live-births, fetal-losses, abortions, and pregnant women for all Texas counties in the year 2010, as well as the estimation method source code.

Project description:PurposeOmphalocele is a congenital abdominal wall defect associated with a high risk of morbidity and mortality, with co-occurring congenital malformations often being the most important prognostic factor. High rates of spontaneous and medical terminations have been reported among pregnancies with omphalocele and co-occurring malformations. Few studies have focused on co-occurring malformations, particularly non-gastrointestinal malformations among live births. This study examined birth prevalence of omphalocele and co-occurring major malformations among a 25-year Danish liveborn cohort.MethodsThis nationwide retrospective prevalence study used data from the Danish National Patient Register and Danish Civil Registration System for infants who were delivered in Denmark during 1997-2021 and included in the Danish neonatal screening biobank. Diagnoses of omphalocele and co-occurring malformations were ascertained and prevalence estimated using Poisson regression.ResultsAmong 1,498,685 live births, 147 infants with omphalocele were identified, yielding a combined and stable prevalence (per 10,000 infants) of 0.98 (95% CI 0.83-1.15). Over one-half (53.7%) presented with one or more major malformations, and an additional 17.0% were diagnosed with a syndrome.ConclusionsOmphalocele birth prevalence in Denmark was stable over a recent 25-year period. The proportion of infants with co-occurring major malformations or diagnosed syndrome has important implications for long-term healthcare demands.

Project description:Here we report urine-derived cell (UDC) culture and subsequent use for cloning which resulted in the successful development of cloned canine pups, which have remained healthy into adulthood. Bovine UDCs were used in vitro to establish comparative differences between cell sources. UDCs were chosen as a readily available and noninvasive source for obtaining cells. We analyzed the viability of cells stored in urine over time and could consistently culture cells which had remained in urine for 48hrs. Cells were shown to be viable and capable of being transfected with plasmids. Although primarily of epithelial origin, cells were found from multiple lineages, indicating that they enter the urine from more than one source. Held in urine, at 4°C, the majority of cells maintained their membrane integrity for several days. When compared to in vitro fertilization (IVF) derived embryos or those from traditional SCNT, UDC derived embryos did not differ in total cell number or in the number of DNA breaks, measured by TUNEL stain. These results indicate that viable cells can be obtained from multiple species' urine, capable of being used to produce live offspring at a comparable rate to other cell sources, evidenced by a 25% pregnancy rate and 2 live births with no losses in the canine UDC cloning trial. This represents a noninvasive means to recover the breeding capacity of genetically important or infertile animals. Obtaining cells in this way may provide source material for human and animal studies where cells are utilized.

Project description:ObjectivesAssess preferences for and use of medication abortion in Texas after implementation of two policy changes: a 2013 state law restricting medication abortion and the FDA label change for mifepristone in 2016 nullifying some of this restriction.Study designWe analyzed surveys conducted in 2014 and 2018 with abortion patients at 10 Texas abortion facilities. We calculated the percentage of all respondents with an initial preference for medication abortion by survey year, and the type of abortion obtained or planned to obtain among those who were at <10 weeks of gestation. We used multivariable-adjusted mixed-effects Poisson regression models to assess factors associated with medication abortion preference and actual/planned use.ResultsOverall, 156 (41%) of 376 respondents in 2014 and 247 (55%) of 448 respondents in 2018 reported initial preference for medication abortion (Prevalence ratio [PR]: 1.28; 95% CI 1.03-1.59). Among those who were <10 weeks of gestation and initially preferred medication abortion, 39 of 124 (31%) obtained or were planning to obtain the method in 2014, compared with 188 of 223 (84%) in 2018 (PR: 2.65; 95% CI: 1.69-4.15). After multivariable adjustment, respondents who initially preferred medication abortion and were 7 to 9 weeks of gestation at the time of their ultrasonography (vs <7 weeks) were less likely to obtain or plan to obtain the method (PR: 0.69; 95% CI: 0.57-0.84).ConclusionsAbortion patients were more likely to prefer and obtain or plan to obtain their preferred medication abortion after legal restrictions in Texas were nullified.ImplicationsState policies can affect people's ability to obtain their preferred abortion method. Efforts to provide both abortion options whenever possible, and inform people where each can be obtained, remains an important component of person-centered care despite increasing state abortion restrictions and bans following the reversal of Roe v Wade.

Project description:ImportanceFollowing the US Supreme Court ruling in Dobbs v Jackson Women's Health Organization, Georgia's law limiting abortion to early pregnancy, House Bill 481 (HB481), was allowed to go into effect in July 2022.ObjectivesTo estimate anticipated multiyear effects of HB481, which prohibits abortions after detection of embryonic cardiac activity, on abortion incidence in Georgia, and to examine inequities by race, age, and socioeconomic status.Design, setting, and participantsThis repeated cross-sectional analysis used abortion surveillance data from January 1, 2007, to December 31, 2017, to estimate future effects of HB481 on abortion care in Georgia, with a focus on the 2 most recent years of data (2016 and 2017). Abortion surveillance data were obtained from the 2007-2017 Georgia Department of Public Health's Induced Termination of Pregnancy files. Linear regression was used to estimate trends in abortions provided at less than 6 weeks' gestation and at 6 weeks' gestation or later in Georgia, and χ2 analyses were used to compare group differences by race, age, and educational attainment. Data were analyzed from July 26 to September 22, 2022.ExposuresHB481, Georgia's law limiting abortion to early pregnancy.Main outcome and measuresWeeks' gestation at abortion (<6 vs ≥6 weeks).ResultsFrom January 1, 2007, to December 31, 2017, there were 360 972 reported abortions in Georgia, with an annual mean (SD) of 32 816 (1812) abortions. Estimates from 2016 to 2017 suggest that 3854 abortions in Georgia (11.6%) would likely meet eligibility requirements for abortion care under HB481. Fewer abortions obtained by Black patients (1943 [9.6%] vs 1280 [16.2%] for White patients), patients younger than 20 years (261 [9.1%] vs 168 [15.0%] for those 40 years and older), and patients with fewer years of education (392 [9.2%] with less than a high school diploma and 1065 [9.6%] with a high school diploma vs 2395 [13.5%] for those with some college) would likely meet eligibility requirements under HB481.Conclusions and relevanceThese findings suggest that Georgia's law limiting abortion to early pregnancy (HB481) would eliminate access to abortion for nearly 90% of patients in Georgia, and disproportionately harm patients who are Black, younger, and in lower socioeconomic status groups.

Project description:PurposeWe investigated the contribution of subchorionic hematoma (SCH) involvement in early pregnancy to the risk of pregnancy complications in women who underwent frozen-thawed embryo transfer (FET).MethodsA hypoechogenic area surrounding the gestational sac at early pregnancy on ultrasound was defined as SCH. Simultaneously, the presence of vaginal bleeding was evaluated. We included 1416 women with live births after FET between March 2015 and September 2018 in this study. The frequency of pregnancy complications was compared between the SCH (n = 340) and non-SCH (n = 1076) groups.ResultsThe adjusted odds ratio of abnormal placental adhesion and placenta previa for the SCH group relative to the non-SCH group was 7.01 [2.96-18.00] and 3.77 [1.24-11.91], respectively. In contrast, hypertensive disorders of pregnancy, non-reassuring fetal status, fetal growth restriction, chorioamnionitis, and premature rupture of the membrane showed no differences between both groups. Furthermore, the frequency of abnormal placental adhesion was higher in the SCH group with vaginal bleeding than in the SCH group without vaginal bleeding.ConclusionsSubchorionic hematoma in early pregnancy may cause abnormal placental adhesion and placenta previa in pregnant women with FET. SCH presence should be carefully noted, particularly in cases with vaginal bleeding during early pregnancy after FET.

Project description:BackgroundStudies of the effects of prenatal environmental exposures on postnatal outcomes are particularly vulnerable to live birth bias; i.e., the bias that arises from the necessary restriction of the analysis to live births when that is influenced by both the exposure under study A and unmeasured factors U that also affect the outcome.ObjectivesIn the context of a recent publication of nitrogen dioxide (NO2) and autism spectrum disorder (ASD) that found an odds ratio (OR) of 0.77 per 5.85 ppb NO2 during pregnancy, we aimed to examine what parameters would be needed to account for this protective association through live birth bias.MethodsWe simulated the magnitude of bias under two selection mechanisms and when both mechanisms co-occur, assuming a true null effect. Simulation input parameters were based on characteristics of the original study and a range of plausible values for the prevalence of unmeasured factor U and the ORs for the selection effects (i.e., the effects of NO2 and U on loss and of U on ASD). Each scenario was simulated 1,000 times.ResultsWe found that the magnitude of bias was small when NO2 and U independently influenced pregnancy loss (collider-stratification without interaction), was stronger when NO2-induced loss preferentially occurred in U=1 (depletion of susceptibles), and was strongest when both mechanisms worked together. For example, ORs of 3.0 for NO2-loss, U-loss, U-ASD, and U prevalence=0.75 yielded NO2-ASD ORs per 5.85 ppb NO2 of 0.95, 0.89, and 0.75 for the three scenarios, respectively. The bias is amplified with multiple Us, yielding ORs as low as 0.51.DiscussionOur simulations illustrate that live birth bias may lead to exposure-outcome associations that are biased downward, where the extent of the bias depends on the fetal selection mechanism, the strength of that selection, and the prevalence of U. https://doi.org/10.1289/EHP7961.
