Influence of past reproductive performance on risk of spontaneous abortion.

OBJECTIVE--To investigate the incidence of spontaneous abortion in a population of women in order to establish their risk of spontaneous abortion and the obstetric factors predisposing to it. DESIGN--Prospective study of women recruited by radio and poster appeal and from hospital outpatient clinics. SETTING--English provincial community. PATIENTS--630 Women from the general population intending to become pregnant. INTERVENTIONS--The viability of the pregnancy was assessed by abdominal ultrasonography before completion of the eighth week, and the assessment was repeated if vaginal bleeding occurred. MAIN OUTCOME MEASURE--Spontaneous abortion or live births in women with or without a previous history of spontaneous abortion. RESULTS--The overall incidence of clinically recognisable spontaneous abortion before 20 weeks of gestation was 12% (50/407 pregnancies). The risk of spontaneous abortion in each category of patient was classified with respect to the patient''s past reproductive performance and found to be influenced greatly by her previous obstetric history. In primigravidas and women with a history of consistently successful pregnancies the incidences of abortion were low (5% (4/87) and 4% (3/73) respectively), whereas women with only unsuccessful histories had a much greater risk of aborting the study pregnancy (24% (24/98)), even when their sole pregnancy had ended in abortion (20% (12/59)). The outcome of the last pregnancy also influenced the outcome of the study pregnancy; only 5% of women (5/95) whose previous pregnancy had been successful aborted, whereas the incidence of loss of pregnancy among women whose last pregnancy had aborted was 19% (40/214). CONCLUSIONS--A knowledge of the patient''s reproductive history is essential for the clinical assessment of her risk of spontaneous abortion. As the most important predictive factor for spontaneous abortion is a previous abortion, the outcome of a woman''s first pregnancy has profound consequences for all subsequent pregnancies.     

The Viable Violinist

In the aftermath of the Kermit Gosnell trial and Giubilini and Minerva's article ‘After‐birth abortion’, abortion‐rights advocates have been pressured to provide an account of the moral difference between abortion, particularly late‐term abortion, and infanticide. In response, some scholars have defended a moral distinction by appealing to an argument developed by Judith Jarvis Thomson in A defense of abortion. However, once Thomson's analogy is refined to account for the morally relevant features of late‐term pregnancy, rather than distinguishing between late‐term abortion and infanticide, it reinforces their moral similarity. This is because late‐term abortion requires more than detachment – it requires an act of feticide to ensure the death of the viable fetus. As such, a Thomsonian account cannot be deployed successfully as a response to Giubilini and Minerva. Those wishing to defend late‐term abortion while rejecting the permissibility of infanticide will need to provide an alternative account of the difference, or else accept Giubilini and Minerva's conclusion.     

Pregnancy complicated by psittacosis acquired from sheep.

Two cases of chlamydial infection in pregnant women are described, the first serologically proved and the second suspected. In both cases the infection was probably contracted from sheep suffering with enzootic abortion. Both patients were farmers'' wives who had helped their husbands and lambing and developed a non-specific febrile illness in late pregnancy. In the first case as there was no clinical improvement after 26 hours the patient was delivered by caesarean section of a live infant in good condition; the patient recovered fully. The second patient had presented a year earlier, the fetus had died in the uterus, and the patient himself died after spontaneous labour and forceps delivery 14 hours after admission. Both patients developed disseminated intravascular coagulation. As the casual agent in enzootic abortion in ewes has a predilection for the placenta, early delivery may be the management of choice in late pregnancy if infection with this organism if suspected.     

血清妊娠相关血浆蛋白A在诊断异常妊娠中的临床意义

目的:探讨血清妊娠相关血浆蛋白A(PAPP-A)在诊断异常妊娠中的临床意义,分析其与异常妊振的关系。方法:选取299例5~13周的正常早孕妇为正常早孕组,同期选取稽留流产86例,先兆流产54例,异位妊娠76例为异常妊娠组,用酶联免疫吸附试验(ELASA)测定两组受试者的血清PAPP-A水平,分析两组受试者各个孕周内的血清PAPP-A水平的差异。结果:稽留流产孕妇在各个孕周内(9~13周)的血清PAPP-A水平显著低于同孕周内正常早孕孕妇(t值分别为9.500,8.113,3.511,9.538,8.504,P值均0.05);稽留流产孕妇总的平均血清PAPP-A水平亦低于常早孕孕妇(t=3.651,P值均0.05);异位妊娠孕妇在各个孕周内(9~13周)的血清PAPP-A水平显著低于同孕周内正常早孕孕妇(t值分别为7.976,9.030,9.941,11.625,14.079,12.569,P值均0.05),异位妊娠孕妇总的平均血清PAPP-A水平亦低于常早孕孕妇(t=28.168,P值均0.05);先兆流产孕妇(除孕8周)与正常早孕妊娠血清PAPP-A水平比较无显著统计学意义。结论:血清PAPP-A水平在异常妊娠如异位妊娠、稽留流产中显著降低,可作为诊断异位妊娠、稽留流产及先兆流产辅助诊断的生物学指标。     

Applications for abortion at a community hospital

Applications for therapeutic abortion over a 44-week period in a 647-bed community hospital are reviewed with reference to age, marital status, gestational age, parity, contraceptive use and reasons for application for abortion.The largest age group consisted of those 20 to 29 years old; it accounted for more than twice as many applicants as any other decade. Fifty-four percent were single; married women or those living in stable common-law relationships accounted for 31.7%. Gestational age at application was 8 weeks or less in 68.3%. Those presenting late (i.e. after 14 weeks) were mostly in the younger age groups. No contraceptive measures were being employed at the time of conception by 69.7%. Less than one sixth of the patients were applying because of severely adverse social, psychological or medical reasons.     

Abortion-seeking behaviour among Nigerian women

This study used data from a community-based survey to examine women's experiences of abortion in Nigeria. Fourteen percent of respondents reported that they had ever tried to terminate a pregnancy, and 10% had obtained an abortion. The majority of women who sought an abortion did so early in the pregnancy. Forty-two percent of women who obtained an abortion used the services of a non-professional provider, a quarter experienced complications and 9% sought treatment for complications from their abortions. Roughly half of the women who obtained an abortion used a method other than D&C or MVA. The abortion prevalence and conditions under which women sought abortions varied by women's socio-demographic characteristics. Because abortion is illegal in Nigeria except to save the woman's life, many women take significant risks to terminate unwanted pregnancies. Reducing the incidence of unwanted pregnancy and unsafe abortion can significantly impact the reproductive health of women in Nigeria.     

Sequelae and support after termination of pregnancy for fetal malformation.

A retrospective study examined the reactions to the termination of pregnancy for fetal malformation and the follow up services that were available. Women resident in Mid Glamorgan who had had a termination between 1977 and 1981 because of positive findings after midtrimester prenatal diagnostic tests for neural tube defect or chromosome abnormalities were interviewed at home using a semistructured interview schedule. Three retrospective internal comparison groups were formed from those women who had also had a spontaneous abortion, previous stillbirth, or neonatal death or previous termination for medicosocial reasons early in pregnancy. Of the 48 women interviewed, 37 (77%) experienced an acute grief reaction after the index pregnancy was ended. This reaction was akin to that documented after stillbirth or neonatal death. Twenty two women (46%) remained symptomatic six months after the pregnancy had been ended, some requiring psychiatric support, compared with no such reaction after spontaneous abortion or termination for medicosocial reasons. All the women who had previously had a stillbirth or neonatal death were visited at home either by the general practitioner or by the midwife after that event but such follow up was limited to only eight of the study group after termination for fetal malformation. The findings suggest that support is inadequate for these patients and that improved follow up and counselling services may lessen the adverse sequelae of termination for fetal malformation.     

印记基因PEG10 在葡萄胎组织中的表达以及意义

目的:通过免疫组化方法,探讨印记基因PEG10在葡萄胎组织中的表达及其在早期鉴别葡萄胎妊娠中的应用价值。方法:选取经病理组织学诊断为完全性葡萄胎、部分性葡萄胎、正常早孕、难免流产的标本共计156例,采用免疫组织化学技术检测PEG10在其中的表达,研究遗传印记基因PEG10在葡萄胎妊娠以及非葡萄胎妊娠中的表达。结果:PEG10在四组蜕膜组织中均有表达,在难免流产组呈弱阳性表达,在正常早孕组呈弱阳性和中度阳性表达,在部分性葡萄胎组中呈中度阳性和强阳性表达,在完全性葡萄胎组中呈强阳性表达。PEG10在葡萄胎妊娠组表达明显增多于非葡萄胎妊娠组,两组比较具有显著性差异(P0.01),部分性葡萄胎组表达增多于难免流产组,两组比较差异有显著性(P0.05)。结论:遗传印记基因PEG10在葡萄胎组织中的表达明显高于正常早期妊娠和难免流产组,PEG10基因表达上调与葡萄胎的发生可能有重要关系,是否可将其用于病理诊断鉴别困难时的辅助手段。     

Recurrent spontaneous abortion and polycystic ovarian disease: comparison of two regimens to induce ovulation.

OBJECTIVE--To determine whether pituitary suppression before induction of ovulation reduces the rate of spontaneous abortion in women with polycystic ovarian disease and primary recurrent spontaneous abortions. DESIGN--Closed, randomised, sequential trial. Pairs of women were allocated to each treatment by the toss of a coin. SETTING--Supraregional clinic for women who had had recurrent spontaneous abortions. SUBJECTS--Forty two women with polycystic ovarian disease and primary recurrent spontaneous abortions. INTERVENTIONS--Ovulation was induced by clomiphene or pituitary suppression with buserelin followed by pure follicle stimulating hormone. MAIN OUTCOME MEASURES--Preference for a particular treatment was noted. A preference occurred when one woman in a pair had a successful pregnancy (defined as one of over 12 weeks'' gestation) and one had a spontaneous abortion; the preference was for the treatment resulting in the successful pregnancy. RESULTS--Spontaneous abortions occurred in 11 of 20 women given clomiphene compared with two of 20 who had pituitary suppression. Eleven preferences were found for buserelin and two for clomiphene. In seven pairs both women had successful pregnancies. One pair was discarded because one of the women did not become pregnant. The ratio of luteinising hormone concentration to follicular diameter was found to be a possible diagnostic indicator of spontaneous abortion. CONCLUSION--Pituitary suppression before induction of ovulation significantly reduces the risk of spontaneous abortion in women with polycystic ovarian disease and primary recurrent spontaneous abortions.     

Abortion experience among obstetric patients at Korle-Bu Hospital, Accra, Ghana

Hospital admissions for complications of abortion have been increasing in Africa, indicating a rise in the incidence of abortion. In all pregnant women ever admitted to Korle-Bu hospital in Accra, Ghana, the chance that the outcome of their last pregnancy was an induced abortion decreased as the number of previous pregnancies increased. Women with higher levels of education were more likely to have their 1st pregnancy terminated in an induced abortion. Younger women were more likely than older women at each level of education to have an induced abortion terminate a 1st pregnancy. The use of contraceptives during the last pregnancy interval increased with the level of education of the woman and the number of previous pregnancies. Contraceptive use was also highest among women whose last pregnancy outcome was an induced abortion. The mean pregnancy interval decreased with increasing number of previous pregnancies for both women who used and who did not use contraceptives during their last pregnancy interval. But the mean pregnancy interval was higher among women who used contraceptives. It appears that the abortion experience in this region of Africa is most common in lower parity young women with high levels of education who desire to delay a 1st birth or to space births. This is in contrast in Latin America and other developing countries in which abortion is used mainly by older, married, urban women to limit family size. Contraceptive use in this region of Africa is low, indicating the need for more family planning programs and increasing use of existing programs.     

Attitudes towards abortion in the Danish population

This article reports the results of a survey, by mailed questionnaire, of the attitudes among a sample of the Danish population towards abortion for social and genetic reasons. Of 1080 questionnaires sent to a random sample of persons between 18 and 45 years, 731 (68%) were completed and returned.
A great majority of the respondents were liberal towards early abortion both for social reasons and in case of minor disease. In contrast, there was controversy about late abortions for social reasons and in the case of Down syndrome. Further there was strong reluctance to accept late abortion in case of minor disease.
An analysis of the response patterns showed that most of the respondents had gradualist views on abortion, i.e. they would allow all early abortions, but only abortions for some reasons later in pregnancy. It was also found that the number who would find an early abortion acceptable in general was much higher than the number who would accept it in their own case. These findings suggest that a great part of the resistance towards abortion does not rest on a concern for the rights and interests for the fetus. Instead it may be explained on a view according to which fetal life is ascribed intrinsic moral value.     

Suicides after pregnancy in Finland, 1987-94: register linkage study.

OBJECTIVE: To determine rates of suicide associated with pregnancy by the type of pregnancy. DESIGN: Register linkage study. Information on suicides in women of reproductive age was linked with the Finnish birth, abortion, and hospital discharge registers to find out how many women who committed suicide had had a completed pregnancy during her last year of life. SETTING: Nationwide data from Finland. SUBJECTS: Women who committed suicide in 1987-94. RESULTS: There were 73 suicides associated with pregnancy, representing 5.4% of all suicides in women in this age group. The mean annual suicide rate was 11.3 per 100,000. The suicide rate associated with birth was significantly lower (5.9) and the rates associated with miscarriage (18.1) and induced abortion (34.7) were significantly higher than in the population. The risk associated with birth was higher among teenagers and that associated with abortion was increased in all age groups. Women who had committed a suicide tended to come from lower social classes and were more likely to be unmarried than other women who had had a completed pregnancy. CONCLUSIONS: The increased risk of suicide after an induced abortion indicates either common risk factors for both or harmful effects of induced abortion on mental health.     

Elevated viral antibody titres in spontaneous abortion

To assess the possible role of virus infections in spontaneous abortion we undertook a prospective study of three groups of patients: women who had a spontaneous abortion; women seen in the antenatal booking clinic; and those undergoing therapeutic termination of pregnancy. Venous blood was taken for antibody detection, cervical swabs for virus isolation, and in the cases of spontaneous and therapeutic abortion products of conception were sent for virus culture. The infectious agents studied were influenza A and B, adenovirus, respiratory syncytial virus, measles, psittacosis, Varicella zoster, and mumps virus. Statistical analysis revealed that women in the spontaneous abortion group has a higher incidence of antibodies against respiratory syncytial virus (P less than 0.01), and mumps virus (P less than 0.01). Among women seropositive for each virus, higher titres were found only for respiratory syncytial virus (P less than 0.05) in cases rather than controls. These results could be explained if viruses such as respiratory syncytial virus caused abortion or if women having a spontaneous abortion mount exaggerated immune responses to fetal and viral infections, and the former altered immune response is associated with spontaneous abortion.     

Fetal tissue transplantation and abortion decisions: a survey of urban women.

OBJECTIVE: To describe women''s attitudes and predicted behaviour regarding the potential for fetal tissue transplantation (FTT) to influence abortion decisions. DESIGNS: Self-administered questionnaire survey by mail. SETTING: Academic family practice in Toronto. PARTICIPANTS: Random sample of 475 women 18 to 40 years of age selected from the family practice registry of an urban teaching hospital. Family physicians were blind to their patients'' participation, and investigators were blind to the subjects'' identity. Forty questionnaires were undeliverable. Of the remaining 435, 272 (62.5%) were completed. Six of the women were over 40 years of age or did not indicate their age and were excluded, which left 266 (61.1%) questionnaires for analysis. OUTCOME MEASURES: Number of women who would (a) be more likely to have an abortion if they could donate tissue for FTT and (b) feel better or worse about choosing abortion if FTT were an option, and open-ended comments about the potential for FTT to influence abortion decisions. RESULTS: Of the 266 respondents 32 (12.0%) reported that they would be more likely to have an abortion if they could donate tissue for FTT, 178 (66.9%) stated that they would not be more likely to do so, and 56 (21.1%) were uncertain. Of the 122 who indicated that they would consider an abortion if they were pregnant, 21 (17.2%) stated that they would be more likely to have an abortion if they could donate tissue for FTT, 77 (63.1%) replied that they would not be more likely to do so, and 24 (19.7%) were uncertain. The women 25 to 33 years of age were more likely to be influenced by FTT than the younger or older women, and the women 18 to 24 years were more uncertain about the influence of FTT on abortion decisions than the older women. In written responses some of the women felt that FTT might make abortion decisions easier; many were troubled that FTT might be used to justify a morally problematic abortion decision and felt that FTT should not be used to justify abortion. CONCLUSION: The data, the first of their kind gathered from from women, suggest that some women''s abortion decisions may be influenced by the option to donate tissue for FTT. Further research is necessary to explore the mechanism of influence.     

Feto-maternal haemorrhage in therapeutic abortion

The incidence of feto-maternal haemorrhage in induced abortion has been studied with the Kleihauer technique. All four methods of termination used were shown to result in such haemorrhages. The incidence below 12 weeks'' gestation, however, was very small and there seems to be no reason for offering routine rhesus-immunoglobulin to these women. When it is essential to terminate a pregnancy of 12 weeks'' size or more in a rhesus-negative woman immunoglobulin should be given.

‘This Is Real Misery’: Experiences of Women Denied Legal Abortion in Tunisia

Barriers to accessing legal abortion services in Tunisia are increasing, despite a liberal abortion law, and women are often denied wanted legal abortion services. In this paper, we seek to explore the reasons for abortion denial and whether these reasons had a legal or medical basis. We also identify barriers women faced in accessing abortion and make recommendations for improved access to quality abortion care. We recruited women immediately after they had been turned away from legal abortion services at two facilities in Tunis, Tunisia. Thirteen women consented to participate in qualitative interviews two months after they were turned away from the facility. Women were denied abortion care on the day they were recruited due to three main reasons: gestational age, health conditions, and logistical barriers. Nine women ultimately terminated their pregnancies at another facility, and four women carried to term. None of the women attempted illegal abortion services or self-induction. Further research is needed in order to assess abortion denial from the perspective of providers and medical staff.     

Pregnancy and Crohn's Disease

Of 77 married women with Crohn''s disease, 25 were sterile. In the remaining 52 (98 pregnancies) the risks of prematurity, stillbirth, abortion, or congenital abnormality were not increased. There was no evidence that pregnancy exerted adverse effects on the course of the disease or increased the mortality rate. Sterility was the main problem encountered.
