Methods for the assessment of selection bias in drug safety during pregnancy studies using electronic medical data

Electronic health data are routinely used for population drug studies. Due to the ethical dilemma in carrying out experimental drug studies on pregnant women, the effects of medication usage during pregnancy on fetal and maternal outcomes are largely evaluated using this data collection medium. One major limitation in this type of study is the delayed inclusion of pregnancies in the cohort. For example, in the province of Quebec, Canada, a major pregnancy cohort only captured pregnancies after 20 weeks gestation. The purpose of this study was to demonstrate three methods that can be used to assess the extent of selection bias due to the delayed inclusion of pregnancies. We use causal directed acyclic graphs to explain the source of this selection bias. In an example involving a cohort of pregnant asthmatic women reconstructed from the linkage of administrative health databases from the province of Quebec, we use numerical derivations, a simulation study and a sensitivity analysis to investigate the potential for bias and loss of power due to the delayed inclusion. We find that this selection bias can be partially mitigated by controlling for variables related to (spontaneous or therapeutic) abortion and the outcome of interest. The three proposed methods allow for the pre and post hoc ascertainment of the bias. While delayed pregnancy inclusion selection bias (which includes "live birth bias") can produce substantial bias in pregnancy drug studies, all three methods are effective at producing estimates of the size of the bias.

Global, regional, and subregional classification of abortions by safety, 2010-14: estimates from a Bayesian hierarchical model

BACKGROUND

Global estimates of unsafe abortions have been produced for 1995, 2003, and 2008. However, reconceptualisation of the framework and methods for estimating abortion safety is needed owing to the increased availability of simple methods for safe abortion (eg, medical abortion), the increasingly widespread use of misoprostol outside formal health systems in contexts where abortion is legally restricted, and the need to account for the multiple factors that affect abortion safety.

METHODS

We used all available empirical data on abortion methods, providers, and settings, and factors affecting safety as covariates within a Bayesian hierarchical model to estimate the global, regional, and subregional distributions of abortion by safety categories. We used a three-tiered categorisation based on the WHO definition of unsafe abortion and WHO guidelines on safe abortion to categorise abortions as safe or unsafe and to further divide unsafe abortions into two categories of less safe and least safe.

FINDINGS

Of the 55· 7 million abortions that occurred worldwide each year between 2010-14, we estimated that 30·6 million (54·9%, 90% uncertainty interval 49·9-59·4) were safe, 17·1 million (30·7%, 25·5-35·6) were less safe, and 8·0 million (14·4%, 11·5-18·1) were least safe. Thus, 25·1 million (45·1%, 40·6-50·1) abortions each year between 2010 and 2014 were unsafe, with 24·3 million (97%) of these in developing countries. The proportion of unsafe abortions was significantly higher in developing countries than developed countries (49·5% vs 12·5%). When grouped by the legal status of abortion, the proportion of unsafe abortions was significantly higher in countries with highly restrictive abortion laws than in those with less restrictive laws.

INTERPRETATION

Increased efforts are needed, especially in developing countries, to ensure access to safe abortion. The paucity of empirical data is a limitation of these findings. Improved in-country data for health services and innovative research to address these gaps are needed to improve future estimates.

[Therapeutic abortion, unjustified absence in health policy]

Although abortion for health reasons is not considered a crime in Peru, the State does not allow its inclusion in public policy, thus violating women's right to terminate a pregnancy when it affects their health. When examining the article in the Criminal Code which decriminalizes this type of abortion, provisions are identified which protect women and set the conditions to offer this type of service. This document sets the debate about the arguments used by the Peruvian State for not approving a therapeutic abortion protocol which would regulate the provision and financing of therapeutic abortion in public services, and explains why this obligation should be complied with, based on the conceptual framework of "health exception" In addition, it presents two cases brought before the judicial court in which the Peruvian State was found guilty of violating the human rights of two adolescents to whom a therapeutic abortion was denied.

Assisted reproductive technologies in Italy, 2005-2007: results from the Italian Assisted Reproductive Technologies Register

AIM

The aim of this study was to assess the quantitative and qualitative outcomes of assisted reproductive technologies in Italy, from 2005 to 2007, collected by the Italian Assisted Reproductive Technologies Register (IARTR).

METHODS

We analyzed, retrospectively, 121,708 ART treatments performed by Italian assisted reproductive technologies (ART) centres from 2005 to 2007.

RESULTS

In the study period ART Italian centers were reporting data to the IARTR. Number of total cycles (all homologous) reported was 121,708 including 110,074 fresh (FRESH), 8682 frozen/thawed oocytes (FO) and 2952 frozen embryo (FER). Pregnancy rates per cycle with respect to FRESH, FO and FER treatments were 19.1%, 10.2% and 15%, respectively. Delivery rate per cycle with at least one live birth was 10.8%, 5.8% and 8.4%, respectively, per type of procedure. Twin and "triplet or more" birth rate per delivery was 21% and 2.8%; 12% and 0.4%; 14.9% and 0.8%, respectively. During the study period 15923 ART infants were born (0.95% of all newborn in Italy).

CONCLUSION

From 2005 to 2007 we registered a strong increase in ART procedures concomitantly with a qualitative improvement leading to increased pregnancy and live birth rates per cycles. Remarkably, pregnancy loss to follow-up decreased drastically during the three years study-period.

Menstrual regulation, unsafe abortion, and maternal health in Bangladesh

Maternal mortality has declined considerably in Bangladesh over the past few decades. Some of that decline--though precisely how much cannot be quantified--is likely attributable to the country's menstrual regulation program,which allows women to establish nonpregnancy safely after a missed period and thus avoid recourse to unsafe abortion. Key Points. (1) Unsafe clandestine abortion persists in Bangladesh. In 2010, some 231,000 led to complications that were treated at health facilities, but another 341,000 cases were not. In all, 572,000 unsafe procedures led to complications that year. (2) Recourse to unsafe abortion can be avoided by use of the safe, government sanctioned service of menstrual regulation (MR)--establishing nonpregnancy after a missed period, most often using manual vacuum aspiration. In 2010, an estimated 653,000 women obtained MRs, a rate of 18 per 1,000 women of reproductive age. (3) The rate at which MRs result in complications that are treated in facilities is one-third that of the complications of induced abortions--120 per 1,000 MRs vs. 357 per 1,000 induced abortions. (4) There is room for improvement in MR service provision, however. In 2010, 43% of the facilities that could potentially offer it did not. Moreover, one-third of rural primary health care facilities did not provide the service. These are staffed by Family Welfare Visitors, recognized to be the backbone of the MR program. In addition, one-quarter of all MR clients were denied the procedure. (5) To assure that trends toward lower abortion-related morbidity and mortality continue, women need expanded access to the means of averting unsafe abortion. To that end, the government needs to address barriers to widespread, safe MR services, including women's limited knowledge of their availability, the reasons why facilities do not provide MRs or reject women who seek one, and the often poor quality of care.

Decidual endovascular trophoblast invasion in women with polycystic ovary syndrome: an experimental case-control study

CONTEXT

Previous experimental and clinical data suggest impaired decidual trophoblast invasion in patients with polycystic ovarian syndrome (PCOS).

OBJECTIVE

The objective of the study was to test the hypothesis that decidual endovascular trophoblast invasion in pregnant patients with PCOS is impaired and to clarify the potential mechanisms involved.

DESIGN

This was an experimental case-control study.

SETTING

The study was conducted at the academic Departments of Obstetrics and Gynecology and the Unit of Pathology (Italy).

PATIENTS

Forty-five pregnant subjects screened from a wide population of women waiting for legal pregnancy termination were included in the final analysis. Specifically, 15 pregnant patients with PCOS were enrolled as cases and another 30 age- and body mass index (BMI)-matched healthy pregnant women without any feature of PCOS were enrolled as the controls.

INTERVENTION

Interventions included the collection of trophoblastic and decidual tissue at the 12th week of gestation.

MAIN OUTCOME MEASURES

Clinical, ultrasonographic, and biochemical data as well as the histological analysis of decidual endovascular trophoblast invasion.

RESULTS

The rate of implantation site vessels with endovascular trophoblast invasion (ratio between total number of implantation site vessels and total number of vessels with endovascular trophoblast invasion) and the extent of endovascular trophoblast invasion (proportion between immunoreactive areas to cytokeratin 7 and to CD34) were significantly lower in patients with PCOS compared with healthy non-PCOS controls. Endovascular trophoblast invasion data were significantly and indirectly related to the markers of insulin resistance and testosterone concentrations in PCOS patients.

CONCLUSIONS

Pregnant patients with PCOS patients have impaired decidual trophoblast invasion. Further studies are needed to evaluate the exact mechanisms through which insulin resistance and hyperandrogenemia exert this effect.

Confidentiality concerns with mapping survey data in reproductive health research

The increasing availability of georeferenced datasets creates new opportunities to perform spatial analysis of social science and public health survey data, but also raises ethical issues regarding the potential for unintended violation of the confidentiality of respondents. This article examines these ethical challenges by reflecting on the experience of a study mapping the facilities that provide abortion-related services in Cambodia. The technique of masking is examined as a potential method for preventing reidentification of respondents in georeferenced surveys. Broader solutions are offered for ways to balance the potentially conflicting goals of spatial analysis and protection of confidentiality.

[Diaphragmatic hernia in reference hospital ICZMP--diagnostic problems and outcome]

OBJECTIVES

The aim of the study was to analyze US/ECHO examinations in fetuses with diaphragmatic hernia (DH) diagnosed and treated in our institution from 1994-2006, and their follow-up.

MATERIAL AND METHODS

Retrospective analysis of the data base from Department for Diagnoses & Prevention of Fetal Malformations, Research Institute of the Polish Mother's Memorial Hospital: 14,481 fetal echo/ultrasound examinations in 10,077 fetuses have been analyzed to retrieve 115 fetuses with DH.

RESULTS

The mean gestational age at the targeted US/ECHO examination was 30 wks. There were 8 terminations of pregnancies (at mean 21 wks), 6 intrauterine demises, 60 neonatal deaths after delivery (in 1-3rd day of postnatal life), 8 deaths after surgery, 19 neonates were discharged home and in 14 cases the follow-up could not be monitored. The most common anomalies accompanying DH have been central nervous system anomalies (20%), polyhydramnion (16%) and cong heart defects (10%). In this subgroup, there was 100% mortality. Isolated DH has been diagnosed in every third case. In this subgroup, 27 neonates had undergone surgery and the survival rate was 70%, however since 2004 there was not a single death on record.

CONCLUSIONS

Late gestational age of US/ECHO examinations in our tertiary center suggests that DH has been relatively difficult to detect during ultrasound screening. DH and the other structural malformations have been a lethal disease in our series in 100%. Isolated DH was much less frequent and was present in every third case (29%), and in this group the survival rate was 70%, regardless of the way of the delivery (CS or Vaginal).

Pregnancy outcomes in women with inflammatory bowel disease: a large community-based study from Northern California

BACKGROUND & AIMS

The aim of this study was to determine whether pregnancy outcomes differ between women with and without inflammatory bowel disease (IBD) and to determine what risk factors adversely affect outcomes.

METHODS

We conducted a cohort study of all pregnant women within the Northern California Kaiser Permanente membership between the years 1995 and 2002. We abstracted the records of all pregnancies in women with IBD (exposed cohort) and a random sample of pregnancies from age-matched women without IBD (unexposed cohort) and evaluated risk factors for spontaneous abortion, complications of pregnancy, and adverse newborn events.

RESULTS

A total of 461 pregnant women with IBD were matched to 493 unexposed pregnant women. Women with IBD were more likely to have an adverse conception outcome (odds ratio, 1.65; 95% confidence interval, 1.09-2.48), an adverse pregnancy outcome (odds ratio, 1.54; 95% confidence interval, 1.00-2.38), or a pregnancy complication (odds ratio, 1.78; 95% confidence interval, 1.13-2.81); however, the difference between the 2 groups in adverse newborn outcomes was not statistically significant (odds ratio, 1.89; 95% confidence interval, 0.98-3.69). Independent predictors of an adverse outcome included a diagnosis of IBD, a history of surgery for IBD, and non-Caucasian ethnicity. Severity of disease and medical treatments were not associated with an adverse outcome.

CONCLUSIONS

Women with IBD are more likely to have an adverse outcome related to pregnancy. Disease activity and medical treatment did not predict adverse outcomes in a large, nonreferral population.

[Prenatal diagnosis in the Nord-Pas-de-Calais in 2004: organisational issues and challenges]

The development of the Regional Plan for Health Organisation (SROS III) in the Nord-Pas-de-Calais has provided an opportunity for further reflection on the operation and organisation of professionals and structures in the field of prenatal diagnoses. The alleged claims resulting from this reflection process are not only integrated in the perinatal stream of the SROS but also in the objectives of the regional public health plan. The study which was carried out takes into account the regional data available, complemented by interviews with professionals working on the ground, which are then compared with national data. All of these elements contributed to the construction of proposals for an improved organisation of this regional management system, on the one hand curative and on the other preventive.

Early medical abortion in Cairns, Queensland: July 2006 – April 2007

Mifepristone (RU486), which is used for early medical abortion, can only be obtained in Australia under the Authorised Prescriber legislation (Section 19[5] of the Therapeutic Goods Act 1989 [Cwlth]); two of the authors have permission to obtain, prescribe and administer this drug in Cairns, Queensland. From July 2006 to April 2007, 10 women who fulfilled the Therapeutic Goods Administration (TGA) criteria of "life-threatening or otherwise serious" indications underwent medical abortion with mifepristone/misoprostol, and 12 women conforming with abortion requirements of Queensland law, but not TGA legislation for mifepristone administration, had medical abortions with the less preferable methotrexate/misoprostol combination. Although it is now more than a year since the cross-party vote in federal Parliament in February 2006 confirmed wide support for the right of Australian women to a medical abortion, we believe we are at present the only medical practitioners in Australia with permission to use mifepristone. Obtaining Authorised Prescriber status from the TGA is of necessity a complex and protracted process, involving ethics committee approval and auditing, and regular reporting to the TGA. Because of the current restrictions, we believe that women seeking medical abortion in Australia face barriers not experienced by women in other comparable countries, and that drug manufacturing and distributing companies may be discouraged from seeking to market mifepristone in Australia.

Outcome of pregnancy in women with congenital heart disease: a literature review

A search of peer-reviewed literature was conducted to identify reports that provide data on complications associated with pregnancy in women with structural congenital heart disease (CHD). This review describes the outcome of 2,491 pregnancies, including 377 miscarriages (15%) and 114 elective abortions (5%). Important cardiac complications were seen in 11% of the pregnancies. Obstetric complications do not appear to be more prevalent. In complex CHD, premature delivery rates are high, and more children are small for gestational age. The offspring mortality was high throughout the spectrum and was related to the relatively high rate of premature delivery and recurrence of CHD.

Differences in characteristics among 1,000 women with endometriosis based on extent of disease

OBJECTIVE

To determine the relationship between disease severity and patient characteristics in endometriosis.

DESIGN

Cross-sectional study of self-reported survey data.

SETTING

Academic research setting.

PATIENT(S)

One thousand women in the Oxford Endometriosis Gene (OXEGENE) study.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Participants were assigned to one of two groups with predominantly revised AFS stage I-II (group I, n = 423) or III-IV disease (group II, n = 517). Their characteristics were compared by disease extent.

RESULT(S)

Most participants were white (96%) and of reproductive age (81%). Women in group I were significantly younger on entering the study (39.9 +/- 0.5 vs. 44.5 +/- 0.4 years). Overall time to diagnosis did not differ between groups. The most common symptoms leading to a diagnosis were dysmenorrhea (79%) and pelvic pain (69%). In group II, subfertility (21.5% vs. 30.0%) and an ovarian mass (7.3% vs. 29.4%) more commonly led to a diagnosis, whereas dyspareunia (51.1% vs. 39.5%) was significantly more common in group I. Subfertility (41.5% vs. 53.4%) remained more common in group II throughout reproductive life, although birth and miscarriage rates were similar.

CONCLUSION(S)

Pelvic pain is common to all with endometriosis and those with more extensive disease report higher rates of subfertility. Remarkably, the time to diagnosis was similar among women.

Pregnancy before and after the diagnosis of inflammatory bowel diseases: retrospective case-control study

BACKGROUND AND AIM

Inflammatory bowel diseases (IBD) commonly affect women during the reproductive years. The aim of the present study was to evaluate the reproductive histories of patients with ulcerative colitis (UC) and Crohn's disease (CD) considering pregnancies occurring before and after the diagnosis.

METHOD

Case-control study evaluating IBD patients, interviewed by questionnaire about outcome of pregnancy and course of disease.

RESULTS

A total of 502 pregnancies from 199 patients in the prediagnosis group and 121 pregnancies from 90 patients in the post-diagnosis group were respectively compared with 996 and 204 pregnancies recorded in a control population. In prediagnosis pregnancies, CD was associated with increased risk of preterm delivery (odds ratio [OR] 4.62, 95% confidence interval [CI] 2.77-7.73; P < 0.001 vs controls and OR 3.52, 95% CI 1.75-7.07; P < 0.001 vs UC) and lower birthweight (P < 0.001 vs UC and controls). In post-diagnosis pregnancies, the rate of live births was lower, but not statistically significant in IBD (OR 0.22, 95% CI 0.04-1.25; P = 0.08) and the birthweight was significantly lower in CD than in UC (P < 0.03) and in controls (P < 0.02). In post-diagnosis pregnancies, a higher incidence of congenital abnormalities was found in IBD patients (5.5% vs 0.0%). The spontaneous abortion rate and therapeutic abortions were significantly higher in post than in prediagnosis pregnancies. Neither disease activity at conception nor treatment appeared to influence the outcome of pregnancy.

CONCLUSIONS

CD in the preclinical phase has some influence on pregnancy. In patients with IBD our data suggest that conception should not be discouraged. However, because of a modest increase in mild congenital abnormalities and abortions rates, pregnancy in IBD patients should be closely monitored.

Impact of diagnostic and confirmatory tests and prenatal counseling on the rate of pregnancy termination among women with positive cytomegalovirus immunoglobulin M antibody titers

OBJECTIVE

The purpose of this study was to determine if diagnostic tests performed in a reference laboratory and the correct interpretation and communication of results by an expert physician to the patient can reduce the rate of unnecessary abortions among women with positive cytomegalovirus (CMV) immunoglobulin M antibody titers.

STUDY DESIGN

This was a retrospective study of 1857 consecutive pregnant women with positive screening for IgM anti-CMV, in the first or second trimester of pregnancy, referred to our unit for further diagnostic evaluation. Patients with available follow-up were divided into 2 groups according to the results of confirmatory serologic testing: women with a CMV serologic profile suggestive of primary infection and hence at high risk of vertical transmission (group 1) and women with a CMV serologic profile consistent with nonprimary infection or past infection (group 2). The number of expected pregnancy terminations and the prevented fraction of abortions was calculated.

RESULTS

Of 445 group 1 patients, 53 (11.9%) elected to terminate the pregnancy after being informed of the results of diagnostic tests; in contrast, only 5 (0.4%) women in group 2 underwent terminations (P < .001). At autopsy, 38 fetuses in group 1 proved infected. No information on fetal infection is available for pregnancies terminated in the first trimester (15 in group 1; 5 in group 2). We estimated that > or = 196 (11.9%) of all patients in groups 1 and 2 (n = 1650 patients) would have elected abortion on the basis of the positive result of screening for fetal CMV infection. After the results of confirmatory tests, only 58 women (53 in group 1 and 5 in group 2) elected to terminate the pregnancy. Thus, the number of abortions is presumed to have been decreased by 73% (P < .001).

CONCLUSION

The correct interpretation and communication of confirmatory test results by expert physicians to pregnant women with positive screening for IgM anti-CMV may significantly reduce the rate of unnecessary abortions.

Pregnancy outcomes in women with mechanical heart valves

OBJECTIVE

To evaluate maternal complications and perinatal outcomes in women with mechanical heart valves treated with warfarin and heparin during pregnancy.

STUDY DESIGN

A retrospective chart review was performed on 45 pregnancies in 28 women who were previously fitted with mechanical valve prostheses and treated between 1991 and 2005 at Seoul National University Hospital. Outcome parameters were maternal complications and perinatal outcomes.

RESULTS

Overall, there were 27 live births (60%), 7 stillbirths (15.6%), 2 therapeutic terminations in the second trimester (4.4%), 9 first-trimester spontaneous abortions (20%) and 2 neonatal deaths after preterm delivery. After excluding 9 first-trimester spontaneous abortions and 3 pregnancies administered warfarin throughout pregnancy, there were significantly more live births among patients administered heparin only after a diagnosis of pregnancy than among those administered warfarin from the second trimester (11 of 11 vs. 13 of 22, p = 0.015). One patient with mitral valve thrombosis during heparinization in the first trimester received valve replacement surgery and then aborted. Late postpartum hemorrhage occurred in 1 patient. All stillbirths and therapeutic terminations occurred in women being administered warfarin.

CONCLUSION

Warfarin use from the second trimester in combination anticoagulation regimens increases the risk of an adverse perinatal outcome.

Abortion Training in United States Obstetrics and Gynecology Residency Programs

OBJECTIVE

To identify characteristics of programs which provide training in abortion, to calculate the number of procedures done during training, and to compare the availability of abortion training in 2004 with that of prior national surveys.

METHODS

An investigator-designed questionnaire about abortion training in obstetrics and gynecology residency programs was mailed to all U.S. residency directors. Collected data included program information, abortion training, and numbers of residents trained. Data were analyzed to estimate differences in abortion training by region, program size, and type of training offered.

RESULTS

Of the 252 questionnaires mailed, 185 (73%) were returned. Of the 185, 94 (51%) program directors reported routine instruction in elective abortion, 72 (39%) optional training, and 19 (10%) no training. Large programs and programs located in the Northeast and West Coast were significantly more likely to offer routine training in terminations (P < .01). In the programs offering routine training, more than 50% of residents received instruction in termination practices. Of those practices, the most common were first-trimester surgical abortion (85% of programs), followed by medical abortion (59%), second-trimester induction (51% of programs), and dilation and extraction (36%). As compared with those in programs with optional training, residents in programs with routine training were significantly more likely to receive instruction in all modalities of abortion provision and performed proportionally more first- and second-trimester terminations (P < .01).

CONCLUSION

Routine training in elective abortion resulted in greater exposure to abortion practices and greater experience in more complicated abortion techniques during residency.

Exposure to mirtazapine during pregnancy: a prospective, comparative study of birth outcomes

BACKGROUND

Mirtazapine is a novel piperazinoazepine antidepressant, unrelated to any known class of antidepressants. Currently, apart from a few case reports and case series in the literature, there are no studies evaluating the safety of this drug during pregnancy.

OBJECTIVE

To determine whether mirtazapine increases the risk for major malformations in newborns when used by pregnant women.

METHOD

The study design was prospective, with 2 comparison groups: disease-matched pregnant women diagnosed with depression taking other antidepressants and pregnant women exposed to nonteratogens. The primary outcome was major malformations in neonates; secondary endpoints included spontaneous abortions, therapeutic abortions, gestational age at birth, and mean birth weight. Women were recruited from 5 teratogen information services in Toronto, Canada; Farmington, Conn., U.S.A.; Jerusalem, Israel; Rome, Italy; Sydney, Australia; and from the Drug Safety Research Unit in Southampton, United Kingdom. Women were recruited into the study from June 2002 to August 2005.

RESULTS

We were able to follow 104 pregnancy outcomes in each drug group. There were 77 live births, 1 stillbirth, 20 spontaneous abortions, 6 therapeutic abortions, and 2 major malformations in the mirtazapine group. The mean +/- SD birth weight was 3335 +/- 654 g and the mean +/- SD gestational age at delivery was 38.9 +/- 2.5 weeks. Most (95%) of the women took mirtazapine in the first trimester, but only 25% of the women took it throughout pregnancy. The differences among the 3 groups were in the rate of spontaneous abortions, which was higher in both antidepressant groups (19% in the mirtazapine group and 17% in the other antidepressant group) than in the nonteratogen group (11%), but none of the differences were statistically significant. The rate of preterm births (prior to 37 weeks' gestation) was also higher in the mirtazapine group (10%) and in the other antidepressant group (7%) than in the nonteratogen group (2%). The difference was statistically significant between the mirtazapine group and the nonteratogen group (p = .04).

CONCLUSION

Mirtazapine does not appear to increase the baseline rate of major malformations of 1% to 3%. However, the higher number of spontaneous abortions in the antidepressant groups confirms the higher rates of spontaneous abortions in pregnant women taking antidepressant medications found in previous studies.

Abortion Training in Canadian Obstetrics and Gynecology Residency Programs

OBJECTIVE

To study abortion training in Canadian obstetrics and gynecology (ob-gyn) residency programs.

METHODS

An anonymous questionnaire was sent to all postgraduate year (PGY)-4 and PGY-5 ob-gyn residents (n=130) and residency program directors (n=16) in Canada. The questionnaires inquired about demographic information, details of abortion training, resident participation in training, and intention to provide abortions after residency.

RESULTS

Ninety-two of 130 residents (71%) and 15 of 16 program directors (94%) responded. Abortion training is considered routine in approximately half of programs and elective in half. The majority of residents (71%) participated in abortion training, and half plan to do elective abortions after residency. More than half of residents felt competent after training to perform first-trimester aspiration and second-trimester inductions but did not feel competent in first-trimester medical abortions or dilation and evacuation (D&E). Residents were more likely to participate in training if the program arranged the training for residents (P=.04) and were more likely to intend to provide abortions if the training was considered routine (P=.02), while controlling for all significant demographic and training variables.

CONCLUSION

Most Canadian ob-gyn programs offer some training in elective abortion, but only half include it routinely in training, and the minority of residents feels competent in D&E and medical abortion. Integrated abortion training was associated with greater resident participation in training and increased likelihood of intention to provide abortions after residency.

Germline polymorphisms in SIPA1 are associated with metastasis and other indicators of poor prognosis in breast cancer

Introduction

There is growing evidence that heritable genetic variation modulates metastatic efficiency. Our previous work using a mouse mammary tumor model has shown that metastatic efficiency is modulated by the GTPase-activating protein encoded by Sipa1 ('signal-induced proliferation-associated gene 1'). The aim of this study was to determine whether single nucleotide polymorphisms (SNPs) within the human SIPA1 gene are associated with metastasis and other disease characteristics in breast cancer.

Method

The study population (n = 300) consisted of randomly selected non-Hispanic Caucasian breast cancer patients identified from a larger population-based series. Genomic DNA was extracted from peripheral leukocytes. Three previously described SNPs within SIPA1 (one within the promoter [-313G>A] and two exonic [545C>T and 2760G>A]) were characterized using SNP-specific PCR.

Results

The variant 2760G>A and the -313G>A allele were associated with lymph node involvement (P = 0.0062 and P = 0.0083, respectively), and the variant 545C>T was associated with estrogen receptor negative tumors (P = 0.0012) and with progesterone negative tumors (P = 0.0339). Associations were identified between haplotypes defined by the three SNPs and disease progression. Haplotype 3 defined by variants -313G>A and 2760G>A was associated with positive lymph node involvement (P = 0.0051), and haplotype 4 defined by variant 545C>T was associated with estrogen receptor and progesterone receptor negative status (P = 0.0053 and P = 0.0199, respectively).

Conclusion

Our findings imply that SIPA1 germline polymorphisms are associated with aggressive disease behavior in the cohort examined. If these results hold true in other populations, then knowledge of SIPA1 SNP genotypes could potentially enhance current staging protocols.

Spontaneous and therapeutic abortions and the risk of breast cancer among BRCA mutation carriers

Introduction

BRCA1 and BRCA2 mutation carriers are at increased risk for developing both breast and ovarian cancer. It has been suggested that carriers of BRCA1/2 mutations may also be at increased risk of having recurrent (three or more) miscarriages. Several reproductive factors have been shown to influence the risk of breast cancer in mutation carriers, but the effects of spontaneous and therapeutic abortions on the risk of hereditary breast cancer risk have not been well studied to date.

Methods

In a matched case-control study, the frequencies of spontaneous abortions were compared among 1,878 BRCA1 mutation carriers, 950 BRCA2 mutation carriers and 657 related non-carrier controls. The rates of spontaneous and therapeutic abortions were compared for carriers with and without breast cancer.

Results

There was no difference in the rate of spontaneous abortions between carriers of BRCA1 or BRCA2 mutations and non-carriers. The number of spontaneous abortions was not associated with breast cancer risk among BRCA1 or BRCA2 mutation carriers. However, BRCA2 carriers who had two or more therapeutic abortions faced a 64% decrease in the risk of breast cancer (odds ratio = 0.36; 95% confidence interval 0.16–0.83; p = 0.02).

Conclusion

Carrying a BRCA1 or BRCA2 mutation is not a risk factor for spontaneous abortions and spontaneous abortions do not appear to influence the risk of breast cancer in carriers of BRCA1 or BRCA2 mutations. However, having two or more therapeutic abortions may be associated with a lowered risk of breast cancer among BRCA2 carriers.

Fetal Aortic Valve Stenosis and the Evolution of Hypoplastic Left Heart Syndrome

Background— Fetal aortic valvuloplasty may prevent progression of aortic stenosis (AS) to hypoplastic left heart syndrome (HLHS). Predicting which fetuses with AS will develop HLHS is essential to optimize patient selection for fetal intervention. The aim of this study was to define echocardiographic features associated with progression of midgestation fetal AS to HLHS.

Methods and Results— Fetal echocardiograms were reviewed from 43 fetuses diagnosed with AS and normal left ventricular (LV) length at ≤30 weeks’ gestation. Of 23 live-born patients with available follow-up data, 17 had HLHS and 6 had a biventricular circulation. At the time of diagnosis, LV length, mitral valve, aortic valve, and ascending aortic diameter Z-scores did not differ between fetuses that ultimately developed HLHS and those that maintained a biventricular circulation postnatally. However, all of the fetuses that progressed to HLHS had retrograde flow in the transverse aortic arch (TAA), 88% had left-to-right flow across the foramen ovale, 91% had monophasic mitral inflow, and 94% had significant LV dysfunction. In contrast, all 6 fetuses with a biventricular circulation postnatally had antegrade flow in the TAA, biphasic mitral inflow, and normal LV function. With advancing gestation, growth arrest of left heart structures became evident in fetuses developing HLHS.

Conclusions— In midgestation fetuses with AS and normal LV length, reversed flow in the TAA and foramen ovale, monophasic mitral inflow, and LV dysfunction are predictive of progression to HLHS. These physiological features may help refine patient selection for fetal intervention to prevent the progression of AS to HLHS.

Prevalence of congenital anomalies in five British regions, 1991-99

AIMS

To describe trends in total and live birth prevalence, regional differences in prevalence, and outcome of pregnancy of selected congenital anomalies.

METHODS

Population based registry study of 839,521 births to mothers resident in five geographical areas of Britain during 1991-99. Main outcome measures were: total and live birth prevalence; pregnancy outcome; proportion of stillbirths due to congenital anomalies; and secular trends.

RESULTS

The sample consisted of 10,844 congenital anomalies, giving a total prevalence of 129 per 10,000 registered births (95% CI 127 to 132). Live birth prevalence was 82.2 per 10,000 births (95% CI 80.3 to 84.2) and declined significantly with time. The proportion of all stillbirths with a congenital anomaly was 10.5% (453 stillbirths). The proportion of pregnancies resulting in a termination increased from 27% (289 cases) in 1991 to 34.7% (384 cases) in 1999, whereas the proportion of live births declined from 68.2% (730 cases) to 58.5% (648 cases). Although similar rates of congenital anomaly groups were notified to the registers, variation in rates by register was present. There was a secular decline in the total prevalence of non-chromosomal and an increase in chromosomal anomalies.

CONCLUSIONS

Regional variation exists in the prevalence of specific congenital anomalies. For some anomalies this can be partially explained by ascertainment variation. For others (neural tube defects, diaphragmatic hernia, gastroschisis), higher prevalence rates in the northern regions (Glasgow and Northern) were true differences. Live birth prevalence declined over the study due to an increase in terminations of pregnancy.

Anxiety as a Predictor of Pain Magnitude Following Termination of First-Trimester Pregnancy

OBJECTIVE

The purpose of the study was to investigate anxiety and other factors that may predict pain magnitude following termination of pregnancy (TOP) during the first trimester.

DESIGN

Prospective, nonrandomized study.

SETTING

Department of Obstetrics and Gynecology, Rambam Medical Center in Haifa, Israel.

PATIENTS

Forty consecutive women undergoing TOP.

OUTCOME MEASURES

Women undergoing a TOP were asked to fill out the State-Trait Anxiety Inventory. Pain magnitude was measured by using a visual analog scale (VAS) at 15, 30, and 60 minutes following the procedure. Correlations between state anxiety, trait anxiety, age, parity, number of TOP, gestational age, and pain magnitude were measured.

RESULTS

State anxiety was able to predict pain magnitude on VAS 15 minutes after TOP (P = 0.023), and trait anxiety was able to predict pain magnitude on VAS 30 minutes after TOP (P = 0.013). Other variables failed to show significant results.

CONCLUSIONS

Preoperative assessment of anxiety levels may lead to appropriate treatment in order to alleviate discomfort and ensure pain control outcome.

Accounting for time: insights from a life-table analysis of the efficacy of medical abortion

OBJECTIVE

Previously published analyses have ignored the temporal nature of medical abortion and calculated effectiveness as the proportion of abortions that succeed. By using life tables, we incorporate the important element of time to produce unbiased efficacy rates as well as afford insight into the medical abortion process.

STUDY DESIGN

Using data on 6568 women from 6 previously published mifepristone-misoprostol medical abortion studies, we generated multidecrement life table efficacy curves and evaluated the cumulative probability of successful medical abortion.

RESULTS

Efficacy rates calculated using proportions are biased because of loss to follow-up. Compliance with the medical abortion regimen was high. More than 80% of abortions were complete within a week of receiving mifepristone. Success continued to improve thereafter. Most surgical interventions were unnecessary.

CONCLUSION

Follow-up visits can be scheduled within a week of receiving mifepristone; however, aspirations should not be performed routinely if the abortion is not complete.

Pregnancy outcome in women with prosthetic heart valves

OBJECTIVE

This study was undertaken to evaluate the risks and pregnancy outcome in women with prosthetic heart valves on different anticoagulent regimens.

STUDY DESIGN

A retrospective chart review of 82 pregnancies in 33 women with mechanical valve prostheses at a tertiary referral center from 1987 to 2002. The main outcome measures were major maternal complications and perinatal outcome.

RESULTS

The valve replaced was mitral (60.6%), aortic (18.2%), and both (21.2%). Fifty-four pregnancies (65.9%) resulted in live births, 9 (11.0%) had stillbirths (all on warfarin), and 12 (14.6%) had spontaneous and 7 (8.5%) therapeutic abortions (all on warfarin). The rate of spontaneous abortion was highest in women on warfarin throughout pregnancy (P < .01). The live birth rate was higher in women on heparin compared with those on warfarin (P < .01), and in those on heparin/warfarin compared with warfarin alone (P < .01). There were no maternal deaths; however, 3 patients had mitral valve thrombosis (2 on heparin and 1 on warfarin) necessitating surgery in 1 patient and medical thrombolysis in 2 patients. Hemorrhagic complications occurred in 5 patients, 4 of whom required transfusion.

CONCLUSION

No single anticoagulant regimen confers complete protection from thromboembolic phenomena in pregnancy. Despite a high maternal morbidity rate, the perinatal outcome is acceptable when pregnancy progresses beyond the first trimester.

Contraception before and after termination of pregnancy: can we do it better?

AIM

To compare contraceptive use pre- and post-therapeutic abortion in 1995, 1999 and 2002 in a New Zealand clinic.

METHODS

Retrospective, consecutive case review of women presenting for therapeutic abortion. Anonymous data included demographic details, contraception used at conception, and post-termination contraception.

RESULTS

Pre-conception contraceptive use is significantly declining, with post-termination condom choice increasing. This is predominantly due to increasing numbers of Asian women presenting for abortion. In 2002, 97% of Asian women used no contraception or only condoms pre-conception, and 62% chose condoms or abstinence post-termination. Oral contraceptives are used significantly less by Asian than European women both pre-termination (p = 0.0002) and post-termination (p = 0.00001). Other ethnic groups showed little change in contraceptive use over the study periods.

CONCLUSIONS

It is speculated that ethnic Chinese women lack adequate contraceptive education, demonstrate distrust of non-barrier methods, believe men should provide the prophylactic, and mistakenly believe contraception unnecessary for the first week following menstruation. Abortion may be used for family planning rather than as back up for contraceptive failure. Young Chinese arriving in New Zealand require immediate sexual health education including accurate contraceptive information. Liaison between primary healthcare sectors and policy makers of immigration and other services assisting overseas students is recommended to provide culturally appropriate education.

Initiating contraception in sexually transmitted disease clinic setting: a randomized trial

OBJECTIVE

Our purpose was to determine the effectiveness of sexually transmitted disease (STD) clinic-initiated contraceptive care.

STUDY DESIGN

Nonpregnant women (n=877) attending an urban STD clinic using either no contraception or only condoms were randomly assigned to either an intervention (n=437) or control group (n=440). Both groups received condoms with spermicide and a referral list of primary care providers (PCP) for ongoing reproductive health care, and the intervention group also received enhanced contraceptive counseling, initial provision of contraception, and facilitated referral to a PCP. Outcomes measured at 4-, 8-, and 12-month follow-up were transition to a PCP, effective contraceptive use (ECU), interval pregnancy, and STD.

RESULTS

The median time to PCP transition was 79 days for the intervention group versus 115 days for the control group (P=.007). Rates of ECU were higher for the intervention group than for control group at the 4-month visit (50% vs 22%, P<.0001) as well as the 8-month visit, although in the intervention group ECU diminished over the course of the study. During follow-up, pregnancy outcomes were documented for 229 women (26.1%), for an overall pregnancy rate of 38.2 per 100 person-years of follow-up. Of the 159 pregnancies defined by patient self-report, 153 (96.2%) were described as unintended and 32 (20%) resulted in a therapeutic abortion. The pregnancy rate was 15% lower in the intervention (105/437, 24.0%) than the control group (124/440, 28.2%) (P=.16), but this difference was not statistically significant.

CONCLUSION

The intervention helped women transition to a PCP and initiate ECU but did not significantly reduce the pregnancy rate. More intensive interventions are needed to prevent unintended pregnancy in this high-risk population.

Surveillance of neural tube defects in Israel

BACKGROUND

Open neural tube defects are among the most common malformations of the fetus. Secondary prevention by early diagnosis during pregnancy and abortion of affected fetuses result in a marked reduction of NTD incidence at birth. The dramatic effect of folic acid for primary prevention of these defects led to recommendations for folic acid supplementation in women of reproductive age.

OBJECTIVE

To describe the epidemiologic features of NTD in Israel in 1999-2000.

METHODS

A national registry of NTD was begun in 1999. During the years 1999-2000, a non-syndromic NTD was diagnosed in at least 394 pregnancies (166 anencephaly, 166 spina bifida, 43 encephalocele, and 19 with other types of NTD). The religious-ethnic affiliation was known in 392 cases (209 Jews and 183 non-Jews).

RESULTS

Despite a marked decline in the rate of NTD at birth in the last few decades, the total rates during pregnancy did not change significantly, demonstrating that the changes were secondary to termination of affected pregnancies. At birth, NTD were almost four times more frequent among non-Jews (3.6 per 10,000 live births for anencephaly and 5.9 for spina bifida) than among Jews (anencephaly 1/10,000 live births, spina bifida 1.4/10,000 live births). The complete data of the registry showed an approximately twofold difference in the overall rates during pregnancy between Jews (anencephaly 5.3, spina bifida 4.6, total 11/10,000 live births) and non-Jews (anencephaly 8.8, spina bifida 10.3, total 22.3/10,000 live births). The registry demonstrated that the significant differences in NTD incidence observed at birth between Jews and non-Jews are secondary to a combined effect of a higher frequency of the malformations among non-Jews and a lower proportion of termination of affected pregnancies among non-Jews.

CONCLUSIONS

The data presented here will serve as a basis for evaluating the impact of the Ministry of Health recommendations for folic acid supplementation on the incidence of NTD.

Greater than expected fertility decline in Ghana: untangling a puzzle

This study examines fertility decline that is larger than expected on the basis of recorded increases in contraceptive prevalence in Ghana. The primary sources of data are three Demographic and Health Surveys (DHS) conducted in the country in 1988, 1993 and 1998. First, the trend in fertility and contraceptive prevalence in Ghana is considered and compared with the trend that would be expected on the basis of prior research. Next, an attempt is made to uncover the explanation behind this unexpected trend. Measures of the quality of the survey data are looked at, as well as trends in the proximate determinants of fertility: contraceptive use, marriage and sexual activity, postpartum insusceptibility and induced abortion. Finally, evidence is presented that couples adjust their coital frequency in accordance with their fertility preferences, behaviour that would influence fertility rates but would not be captured by conventional measures of the proximate determinants of fertility.

Incidence of neural tube defects in Ontario, 1986-1999

BACKGROUND

Prenatal screening and the promotion of folic acid intake could affect the incidence of neural tube defects (NTDs). We examined trends in the total NTD incidence, as detected in live births, stillbirths and therapeutic abortions, from 1986 to 1999 in Ontario.

METHODS

To capture cases of NTDs we used data from the Canadian Congenital Anomalies Surveillance System and hospital data on therapeutic abortions. We calculated the total incidence of NTDs by combining the numbers of NTDs occurring in live births, stillbirths and therapeutic abortions.

RESULTS

The total NTD incidence rate increased from 11.7 per 10,000 pregnancies in 1986 to 16.2 per 10,000 in 1995, and it subsequently decreased to 8.6 per 10,000 by 1999. The NTD birth rate (live births and stillbirths) decreased from 10.6 per 10,000 births in 1986 to 5.3 per 10,000 in 1999. The rate of therapeutic abortions with an NTD or hydrocephalus rose from 17.5 per 10,000 abortions in 1986 to 50.7 per 10,000 in 1995 and fell to 28.7 per 10,000 abortions in 1999.

INTERPRETATION

The total NTD incidence rate increased from 1986 to 1995, probably because of increased prenatal screening and better detection of NTDs. The decline from 1995 to 1999 may have been due to increased folic acid intake among women at the time of conception.

Prenatal diagnosis of cardiovascular diseases

Fetal echocardiography is a safe means to obtain reliable anatomical and hemodynamic data of the fetal heart. The procedure is essential for prenatal diagnosis of cardiovascular abnormalities. In addition, fetal echocardiography is useful to follow-up the progression, monitoring during treatment and making a plan of treatment especially in life-threatening cardiac conditions. The objective of this study was to find the distribution of indications for fetal echocardiography, fetal cardiac anomalies detected, outcome of the fetuses and to assess the accuracy of the procedure. A retrospective study was done at Siriraj Hospital, Mahidol University, Bangkok, Thailand. Pregnant women whose fetuses had prenatal echocardiographic data and gave birth from January 1999 to December 2001 were included. The total number of pregnant women was 54 cases. The indications for fetal echocardiography were suspicion of fetal cardiovascular disease by the obstetrician 42.6 per cent, family history of congenital heart diseases 14.8 per cent, multiple organ system anomalies 14.8 per cent, chromosomal anomalies 11.1 per cent, hydrops fetalis 9.3 per cent, maternal systemic diseases 5.6 per cent and previous pregnancy with a dead fetus in utero 1.9 per cent. The gestational age at the time of the first fetal echocardiography ranged from 17 to 39 weeks (median 28 weeks). The number of fetal echocardiography done in each case ranged from 1 to 10 (median 1.4). Prenatal diagnosis of the abnormal cardiovascular system in fetuses was found in 19 cases (35.2%). There were abnormal cardiac anatomies in 42 per cent, cardiac tumors or abnormal masses in 37 per cent and rhythm disturbances in 21 per cent. When compared with postnatal echocardiography and/or autopsy finding, fetal echocardiography had a sensitivity of 100 per cent, specificity of 96.3 per cent and accuracy of 97.8 per cent.

CONCLUSION

Fetal echocardiography has good accuracy in the diagnosis of cardiovascular diseases. Obstetrician's suspicion is important in the prenatal diagnosis of heart disease that would have affected the short and long-term outcome of the fetus.

Pregnancy outcome following gestational exposure to venlafaxine: a multicenter prospective controlled study

OBJECTIVE

Because there are no studies available on the safety of venlafaxine during pregnancy, the authors' goal in this study was to determine whether venlafaxine increases the risk for major malformations.

METHOD

Data on 150 women exposed to venlafaxine during pregnancy in seven pregnancy counseling centers were compared with data from studies of pregnant women who 1) received selective serotonin reuptake inhibitor antidepressants (SSRIs) (N=150) and 2) who received nonteratogenic drugs (N=150).

RESULTS

Among the 150 women who were exposed to venlafaxine during pregnancy, 125 had live births, 18 had spontaneous abortions, and seven had therapeutic abortions; two of the babies had major malformations. There were no significant differences between these women and the two comparison groups on any of the measures analyzed.

CONCLUSIONS

These results suggest that the use of venlafaxine during pregnancy does not increase the rates of major malformations above the baseline rate of 1%-3%.

Characteristics of Pakistani women seeking abortion and a profile of abortion clinics

A study of the characteristics of Pakistani women seeking abortion and a profile of abortion clinics was conducted in 32 abortion clinics in three provincial capitals of the country. All 452 women who had their pregnancies terminated between October and December 1997 were interviewed. Except for 39 women (8.6%), all study subjects were married. A majority of the women (36.6%) were aged >35 years, 61.0% had given birth to > or =5 children, and 40.2% were illiterate. The predominant reasons for abortion were "too many children" (64.4%), contraceptive failure (20.3%), premarital affairs (8.6%), medical reasons (5.4%), and extramarital affairs (1.3%). Nearly two thirds of the abortions were induced by inadequately trained persons. Only 22% of the abortion clinics met the World Health Organization (WHO) standards required for safe termination of pregnancy. At all these clinics, the procedure used to terminate the pregnancy was dilatation and curettage (D&C). Only one clinic was using manual vacuum aspiration (MVA). Induced abortion seems to be fairly common among married women of high parity, advanced age, and low educational status. Keeping in view the large number of terminations, new medical and surgical techniques of pregnancy termination should be introduced to those already providing abortion services.

[Birth mortality and pregnancy terminations: how can collected Diagnosis Related Group System data be used?]

In France since 1995, information on diagnoses and care are routinely collected for each patient hospitalised in a public or private hospital, using the Diagnosis Related Group system. Information on birth events constitutes a good example of possible use of this information for other aims than economic activity evaluation. In this paper, in order to highlight possible epidemiological use, some recommendations are proposed for collecting data on stillbirths and pregnancy terminations. The lack of usual knowledge on these two adverse events is the reason for this choice. While the improvements in prenatal diagnosis lead to an increase in pregnancy terminations, a minimum common core of collected data should allow routine epidemiological monitoring of these adverse perinatal events.

The decision-making process for requests for late termination of pregnancy in Israel

This article outlines and reflects on the current procedure in Israel for requesting late pregnancy terminations and the subsequent decision-making processes. The study population consisted of 183 women who requested late termination of pregnancy (LTP) in Israel during the years 1995-97. The main causes for requests were fetal anomalies and late application. Eighty-two percent of requests were approved, and approval could be predicted by the week of gestation and the reason for application. Ethical dilemmas are described. The need to enhance professional support for women who request LTP, whether they receive approval or not, should be addressed by the health system and social workers in health care.

Pregnancy outcomes after prenatal diagnosis of aneuploidy

OBJECTIVE

To determine the benefits of antenatal diagnoses of fetal aneuploidy in women who continued their pregnancies.

METHODS

A questionnaire was mailed to 51 mothers of children with aneuploidy. Women whose fetuses were diagnosed prenatally comprised the study group and those whose infants were diagnosed at birth were controls. Outcomes measured included an assessment of pregnancy management, neonatal outcome, subjective measures of depression and anxiety, and evaluation of women's emotional and physical experience of the pregnancy. For outcomes measured by nonparametric survey questions, 20 women were needed in each arm to achieve a power of 80% to detect a 2-point difference on a 6-point scale; for our neonatal outcomes, 100 women were needed in each arm to achieve 80% power to detect a difference in length of stay (less than 1 week versus greater than 1 week) or need for surgery.

RESULTS

Thirty-eight women (75%) responded. Most (86%) had children with trisomy 21. Seventeen women (45%) received their child's diagnosis at birth; 21 (55%) had prenatal diagnoses. Demographic measures were similar except that women with prenatal diagnoses attended religious services more frequently (1--3 times per month versus once to several times per year, P =.04). Women with prenatal diagnosis had better perceptions of their physical experience of pregnancy (median score of 10 versus 6 on a 10-point visual analog scale, P =.005) and their emotional experience of the birth (median score of 7.5 versus 2, P =.001). Mental Health Inventory scores were similar between groups. Neonates without prenatal diagnoses were more likely to be transferred to tertiary centers after birth (70% versus 24%, P =.004); lengths of hospital stays and need for surgery were similar. Seventy-one percent (95% confidence interval [CI] 48, 89%) of women with prenatal diagnoses said they would have done nothing differently in the pregnancy compared with 29% (95% CI 10, 56%) of women with diagnoses at birth.

CONCLUSION

Early knowledge of fetal aneuploidy is beneficial to women who continue their pregnancies. These results might be useful when counseling women who do not intend to terminate abnormal pregnancies, but are considering prenatal diagnosis.

Decreasing the need for abortion: challenges and constraints

Voluntary abortion is the most controversial act in the entire field of medical practice, although today, it is a practice that, under different conditions, has been legalized in more than 100 countries, mostly in the developed world. The United Nations has agreed that in no case should abortion be promoted as a method of family planning and, therefore, it should be utilized only when contraception has failed. Overall, 61% of humanity lives in countries where abortion is legal and widely available; 14% in countries where termination is allowed to protect a woman's health; physical, mental, or both; 21% in countries where it can be performed only to save the mother's life and 4% in countries where abortion is not permitted at all. Restrictive legislation, per se, does not represent a valid deterrent to prevent abortion, while it may contribute to an increase in morbidity and mortality associated with pregnancy. In addition, because abortion is outlawed, nothing is done to actively reduce the reasons leading to it. Indeed, the countries with the lowest abortion rates are those where, on the one hand, pregnancy termination is legal and, on the other, sex education and contraceptive knowledge are widely spread.

Social impacts of technological diffusion: prenatal diagnosis and induced abortion in Brazil

Scientific and technological development plays an essential part in shaping contemporary societies, and medicine and health care are considered to be particularly receptive to the incorporation of new concepts, techniques and products, producing impacts not only on the health problems for which they were originally intended, but also varied 'side-effects', less frequently recognised and studied. In this study the point of departure was the hypothesis that the intensive diffusion in Brazil of prenatal ultrasound would create new problems for individuals (pregnant women, their families and health professionals) and society in coping with foetal malformations, due to the existence of a very restrictive induced abortion legislation. The objective of the research was to study the social visibility of these problems, in the written mass media. The period under analysis went from 1991 to 1996. The four most important daily newspapers and two medical council journals were studied, with a criteria oriented selection of articles, and their macrotextual thematic analysis. The results indicate that the basic elements in the relationships between medical technology, prenatal diagnosis, foetal malformations and induced abortions stayed the same along the period - a restrictive Penal Code, the public recognition of the disseminated and usually tolerated practice of induced abortion, done in risky conditions for the majority of women, with very evident consequences on maternal health, a divided Congress, a divided 'public opinion', religious opposition and new scientific and technological practices in health care. Nevertheless, tension between these 'contradictory' factors increases, so much so, that new elements are introduced which make an accommodation possible, without implying in major changes of position. This is achieved through the development of new alliances between Science, the judiciary and obstetrical leaders, which benefit individual initiatives, instead of leading to a public recognition of the problem and changes in the law.

Contraceptive use and pregnancy decision making among women with HIV

HIV is a growing epidemic among women in the United States. This study seeks to determine if knowledge of HIV infection and of the benefits of prenatal zidovudine (ZDV) to decrease vertical HIV transmission is related to decisions about pregnancy planning, contraceptive and condom use, and pregnancy termination among noninjection drug using (IDU) women with HIV. Eighty-two HIV-infected women were interviewed about their pregnancy decisions, contraceptive and condom use, and pregnancy outcome. Data was verified by structured chart review where available. Awareness of HIV infection or knowledge of the benefits of prenatal ZDV use did not significantly influence pregnancy planning, contraceptive choice, use of contraception, or consideration of pregnancy termination. Condom use was extremely low (14.6% consistent use), the majority of pregnancies (68.0%) were unplanned, contraceptive use was low (50.9%), and few pregnancies were terminated (6.3%). Women on Medicaid were significantly less likely than women with private or no insurance to terminate their pregnancy (2/20, 10% vs. 3/5, 60%, p = 0.04, two-tailed Fisher's exact test). Most women (70.0%) reported the most important reason for carrying the pregnancy to term was the desire for a child. In conclusion, among women in this non-IDU, Midwestern cohort, knowledge of HIV infection was not associated with decisions to plan a pregnancy, use contraception if not planning pregnancy, or terminate an unplanned pregnancy.

Report from the National Transplantation Pregnancy Registry (NTPR): outcomes of pregnancy after transplantation

Specific data on pregnancies following transplantation continue to accrue in the National Transplantation Pregnancy Registry (NTPR) in each type of organ recipient, with the following conclusions: 1. While the majority of kidney recipients appear to tolerate pregnancy well, a small percentage develops rejection, graft dysfunction and/or graft deterioration. Overall, there is a slight increase in the mean postpartum creatinine level when compared with the prepregnancy level, which has been noted in previous investigations by the NTPR. One neonatal death attributed to thrombotic cardiomyopathy was noted in a set of twins of a tacrolimus-based kidney recipient, but no other death has been noted in any of the additional reports among the recipients given newer immunosuppression regimens. Follow-up of offspring of these recipients is ongoing. 2. No structural malformations have been noted among offspring exposed to mycophenolate mofetil, but exposures are limited. (5 mothers, 29 fathers). 3. Female liver recipients with biopsy-proven acute rejection during pregnancy appear to be at greater risk for both poorer newborn outcomes and recurrent rejection episodes. In the setting of acute rejection diagnosed during pregnancy, close attention is warranted, anticipating that birthweight may be lower and that a substantial percentage of these female recipients may have recurrent rejection episodes. 4. Pancreas-kidney grafts can maintain normoglycemia throughout pregnancy. A high incidence of maternal hypertension, prematurity and low birthweight have been noted, so, as in other recipient groups, these are high-risk pregnancies. Maternal pancreas and kidney function must be closely monitored. 5. No specific prepregnancy predictors of adverse outcomes have yet been identified among heart or lung recipients although none of the deaths among heart recipients in the NTPR database occurred within 2 years of delivery. When compared with other solid organ recipients, female lung recipients may face higher risks, particularly related to rejection. Whether prepregnancy factors can help to predict either heart or lung recipients at risk requires continued study. 6. No structural malformations or significant learning disabilities have been noted in follow-up of the offspring of CsA-treated females, the largest group of offspring followed to date with a mean age of 4-5 years. Continued surveillance of children will be essential to determine if effects become apparent as age-related developmental delays or other problems in immune function or fertility later in life. 7. Newer regimens as well as new combinations of agents will continue to be studied. It is essential that non-viable as well as viable pregnancy outcomes be reported to the registry (i.e., recipients with pregnancies that result in spontaneous abortion or termination should be included for study). True estimates of non-viable outcomes have been difficult to assess. Additionally, inclusion of reports of pathologic evaluations at delivery hospitals will be helpful to determine whether spontaneous abortions are a result of lethal malformations related to immunosuppressive or other medication exposure. Safety of pregnancy for parent and child remain the primary goals of the NTPR.

Sexual behavior and pregnancy outcome in HIV-infected women. Canadian Women's HIV Study Group

Sexual behavior and pregnancy outcome data for 392 HIV-infected women were analyzed. During the 6 months before study entry, 71.2% (279 of 392 women) were sexually active. In multivariate regression, women with baseline CD4+ > or = 200/microl were more likely than women with CD4+ < 200/microl to be sexually active (adjusted odds ratio [OR] = 1.75; 95% confidence interval [CI], 1.06-2.88; p = .03). Consistent condom use was reported with 58.4% (149 of 255) of steady male partners and 65.7% (23 of 35) of casual partners. Overall, 90.3% of 279 sexually active women were using contraception. Among women aged between 15 and 44 years (n = 320), the incidence of pregnancy in the year before HIV diagnosis was 27.5 per 100 person-years (PY) (95% CI, 22.1-33.9) compared with 8.3/100 PY (95% CI, 6.8-10.2) in the time since HIV diagnosis (p < .001). The incidence of therapeutic termination of pregnancies conceived in the 20 weeks before HIV diagnosis (10.6/100 PY) was more than triple that after diagnosis (3.1/100 PY; p = .001). After publication of results of zidovudine prophylaxis of mother-to-child transmission, pregnancy rates did not increase, but the incidence of therapeutic abortion dropped from 4.3/100 PY to 1.4/100 PY (p = .009). Knowledge of sexual behavior, including pregnancy frequency and outcome, can assist in tailoring counseling for HIV-infected women concerning sexual and reproductive health.
