A retrospective investigation was undertaken of all the births and abortions during the period 1974-1986 in the County of Funen. The material comprised 66,020 births, 23,179 induced abortions, 9,270 spontaneous abortions and 1,344 ectopic pregnancies. The distributions of the various types of pregnancy were assessed for the entire period and correlated with the age of the women. Comparison of the circumstances in 1974 and 1986 revealed significant changes (p less than 0.05) for pregnant women greater than or equal to 35 years with the following values: the number of births increased 20%, the number of spontaneous abortions increased 56%, the number of ectopic pregnancies increased 240% and the number of induced abortions fell 31%. These numerical values are probably representative for all Denmark.
Estimating the risk of venous thromboembolism (VTE) associated with combined hormonal contraceptives following early terminated pregnancies or birth, a Danish nationwide retrospective cohort observing a one-year follow-up was defined using three unique registries. All Danish women with confirmed pregnancies aged 15-49 during the period of 1995-2009 were included. The main outcomes were relative and absolute risks of first time venous thromboembolism in users as well as non-users of combined hormonal contraceptives. In 985,569 person-years, 598 venous thromboembolisms were recorded. After early terminated pregnancies and births, respectively, 113 and 485 events occurred in 212,552 and 773,017 person-years. After early terminated pregnancies, the crude VTE incidence ratios were similar, and the numbers needed to harm were equal between groups that did or did not use combined hormonal contraceptives throughout the follow-up year. After childbirth, individuals that used combined hormonal contraceptives were more likely than non-users to experience VTE depicted by crude incidence ratios; however, the difference was only significant after 14 weeks. This implied that the numbers needed to harm were lower for those that used compared to those that did not use combined oral contraceptives in the initial 14 weeks postpartum. In conclusion, the use of combined hormonal contraceptives after early terminated pregnancies was not detrimental, but during the puerperal period, they should be used with caution.
AIMS: To compare surgical results for congenital diaphragmatic hernia (CDH) in two Scandinavian university hospitals and to evaluate the effects of abortions on the clinical profile of CDH in Iceland. METHODS: A retrospective study including all CDH-cases in Iceland 1983-2002 and children referred to Lund University Hospital 1993-2002. Aborted fetuses with CDH from a nation-wide Icelandic abort-registry were also included. RESULTS: In Iceland, 19 out of 23 children with CDH were diagnosed
We evaluated the use of curettage in second trimester medical induced abortions retrospectively in 186 women at Herning Hospital, Denmark. Curettage was carried out in a total of 55% of the women. The incidence of curettage was associated with low gestational age (r?=?0.32, p?
Misoprostol can be used in the prevention of gastric ulcer in treatment with diclofenac and is used in rheumatic diseases. Since misoprostol causes contractions of the uterus, it can also be used to induce abortions when administrated vaginally. The aim of the study was to investigate if early pregnancy exposure to oral diclofenac/misoprostol was associated with miscarriage.
We conducted a nationwide cohort study identifying all registered pregnancies in Denmark from 1997 to 2011. All births were identified using the Medical Birth Registry, and all records of induced abortion and miscarriage were from the National Hospital Register. Data on drug use were from the National Prescription Register. Cox proportional hazard regression models were used to calculate the hazard of miscarriage in women exposed to diclofenac/misoprostol in early pregnancy.
We identified 1,338,824 pregnancies (970,491 births, 142,147 miscarriages, 226,145 induced abortions). One hundred sixty-six were exposed to diclofenac/misoprostol in the early pregnancy of which 28.3 % (47) ended up in a miscarriage compared to 10.6 % among unexposed. The adjusted hazard ratio of having a miscarriage after exposure to diclofenac/misoprostol in the first trimester was 3.6 (CI 95 % 2.6-4.9).
We found an increased risk of miscarriage after exposure to diclofenac/misoprostol during the early pregnancy. Women in the fertile age should not be treated with the combination of diclofenac/misoprostol if other options were available.
Neonates with certain forms of severe congenital heart disease (CHD) diagnosed prenatally might have better outcomes in comparison with those diagnosed after birth. The proportion of prenatally detected neonates with severe CHD and the effect of prenatal diagnosis on clinical outcomes have not been previously investigated in Canada.
We retrospectively studied infants in Alberta, Canada, who required surgical or catheter intervention for CHD at younger than 1 year of age, between January 2007 and December 2010, and pregnancy terminations affected by CHD.
Of the 374 subjects identified (327 infants, 47 pregnancies with termination), 188 (50%) were detected prenatally. Failure of prenatal diagnosis was associated with anomalies not involving the 4-chamber view on ultrasound (odds ratio, 1.86; 95% confidence interval, 1.48-2.35; P
the maternal age at child birth is increasing. If induced abortion is an important means of postponing childbirth in a population, it is to be expected that in young women the rate of conceived pregnancies is stable over time, but the induced abortion rate is increasing. We studied birth rates, induced abortion rates and the sum of these rates by maternal age during four decades.
all women 15-49 years living in Norway.
we present temporal changes in birth rates and induced abortion rates within age groups during the period 1979-2007. We also estimated the sum rate of births and induced abortions. Data were obtained from national statistics.
live births and induced abortions per 1000 women per year.
the induced abortion rates have been relatively stable within age groups, except for a decrease in women 15-19 years (from 24.2 in 1979 to 17.0 in 2007) and an increase in women 20-24 years (from 23.2 to 29.5). The birth rates however, have decreased dramatically in women 20-24 years old (from 113.6 to 60.5). Hence, the sum rate of births and induced abortions in women 20-24 years old has decreased from 136.8 to 90.0. In women 30 years old or older, the birth rates have increased.
the induced abortion rate has been relatively stable in all age groups over time, suggesting a limited influence of induced abortions on the postponement of childbearing.
OBJECTIVES: To evaluate the effectiveness of policies and recommendations on folic acid aimed at reducing the occurrence of neural tube defects. DESIGN: Retrospective cohort study of births monitored by birth defect registries. SETTING: 13 birth defects registries monitoring rates of neural tube defects from 1988 to 1998 in Norway, Finland, Northern Netherlands, England and Wales, Ireland, France (Paris, Strasbourg, and Central East), Hungary, Italy (Emilia Romagna and Campania), Portugal, and Israel. Cases of neural tube defects were ascertained among liveborn infants, stillbirths, and pregnancy terminations (where legal). Policies and recommendations were ascertained by interview and literature review. MAIN OUTCOME MEASURES: Incidences and trends in rates of neural tube defects before and after 1992 (the year of the first recommendations) and before and after the year of local recommendations (when applicable). RESULTS: The issuing of recommendations on folic acid was followed by no detectable improvement in the trends of incidence of neural tube defects. CONCLUSIONS: Recommendations alone did not seem to influence trends in neural tube defects up to six years after the confirmation of the effectiveness of folic acid in clinical trials. New cases of neural tube defects preventable by folic acid continue to accumulate. A reasonable strategy would be to quickly integrate food fortification with fuller implementation of recommendations on supplements.
