To examine trends in pregnancy and abortion rates observed in Portugal in the last decade. We abstracted all delivery and abortionrelated-admissions to Portuguese public hospitals (2000–2010) using a nationwide inpatient database(corresponding to nearly 96% of all deliveries). We computed age-specific pregnancy and termination of pregnancy rates (all and induced abortion)considering the age groups less than 15, 15–19, 20–34, 35–39 and more than 39 years, using national population estimates as denominator. Joinpoint regression was used to estimate average annual percent change (AAPC) in rates and to identify points in time when significant changes in trend occurred. Youngest teenager pregnancy rates (less than 15 yrs.)decreased significantly from 0.6 to 0.3 per 1000 women (AAPC=-4.9%; p=0.01) with a non-significant decrease in abortion rates (AAPC=-4.1%; p=0.100). Pregnancy and abortion rates per 1000 15–19 year old girls, showed no significant variation up to 2003 (AAPC=-1.8%;p=0.071 for pregnancy and AAPC=2.5%; p=0.449 for abortion). Then, a significant decrease was observed either in pregnancy (from 20.1 to 14.6; AAPC=-5.2%; p<0.001) and in abortion rates (from 2.5 to 1.5; AAPC =-8.2%; p<0.001). Pregnancy rates per 1000 women aged 20–34 decreased from 78.1 to 66.5. It corresponded to a significant decline up to 2004 (AAPC=-3.1%; p=0.020) but a stable course onwards (AAPC=-0.6%; p=0.389). Abortion rates in this age group steadily decreased from 7.7 to 5.5 per 1000 women (AAPC=-3.24%; p<0.001). In contrast...

O retorno ao estro após a cobertura ou inseminação artificial e o abortamento são as principais falhas reprodutivas observadas nas granjas suínas, exercendo influência sobre os dias não-produtivos e sobre a taxa de reposição do plantel. A determinação dos fatores que influenciam a ocorrência de retorno ao estro após a cobertura e o conhecimento do desempenho reprodutivo de fêmeas reinseminadas após apresentarem retorno ao estro (RE) ou abortamento (AB) tornam-se importantes ferramentas para auxiliar na decisão de remover ou recobrir fêmeas do plantel. Com esses objetivos, esta tese foi realizada, através do desenvolvimento de três experimentos. O primeiro experimento foi realizado para determinar alguns fatores que contribuem para a fêmea retornar ao estro após a inseminação ou cobertura. Fêmeas com cistos ovarianos no momento da IA apresentaram maior chance de retornar ao estro (9,0 vezes mais) do que fêmeas sem cisto (33% x 10,4%). Houve interação entre a classe de ordem de parto (OP) e o dia da semana em que a fêmea foi inseminada, onde fêmeas inseminadas entre quinta e sábado, independente da classe de OP apresentaram maior chance de retornar ao estro. Leitoas e porcas OP1 apresentaram maior chance de retornar ao estro...

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Este trabalho estudou o efeito dos componentes de fecundidade na reprodução de Dahlstedtia pentaphylla, leguminosa neotropical com baixa produção de frutos e sementes. Para tal, foram analisadas as relações das posições das flores na inflorescência e dos óvulos/sementes no ovário/fruto ao aborto de frutos e sementes. Não ocorreram diferenças na deposição de pólen em flores e na formação de frutos em função da posição na inflorescência. Não se encontrou também relação entre aborto de óvulos/sementes e sua posição no ovário/fruto. A limitação dos recursos maternos aos frutos e aos embriões, devido ao alto custo de formação de frutos e maturação das sementes, foi um dos fatores responsáveis pelas altas taxas de aborto nesta espécie.; Studies were conducted on pollination and patterns of fruit and seed production to assess the potential factors causing high fruit and seed abortion in Dahlstedtia pentaphylla (Leguminosae) through analyses of relationships between flower position in the inflorescence and ovules and seeds within ovaries and fruits, and flower, fruit and seed abortion. No differences were found in pollination and fruit set as a function of inflorescence position. There was no relationship...

Dissertação de Mestrado em Engenharia Zootécnica-Produção Animal; De uma população de 250 éguas de Raça Puro-Sangue Lusitano criadas em regime extensivo foram calculados vários parâmetros reprodutivos. Para três décadas (1980 a 2011) foi analisado o intervalo entre partos (média total de 471 dias), a taxa de fertilidade (média total de 84,5%), a sazonalidade reprodutiva (85% dos partos concentrados nos meses de Fevereiro a Abril), a mortalidade dos poldros (7,8% do total de poldros nascidos), a taxa de abortos (média total de 1,64%), entre outros. É de salientar que os resultados obtidos são muito bons para o tipo de produção em que se enquadram, visto que é um regime em que não existe um controlo muito apertado das condições de vida dos animais. O trabalho foi efectuado de modo a permitir o acompanhamento de toda uma época de reprodução e todo o maneio efectuado, bem como os resultados dessa mesma época, são descritos.; ABSTRACT - Description and analysis of some reproductive and productive parameters in a foal production extensive system - Several reproductive parameters of 250 Lusitana mares that were raised in an extensive system were studied.

OBJECTIVE To analyze temporal trends and distribution patterns of unsafe abortion in Brazil. METHODS Ecological study based on records of hospital admissions of women due to abortion in Brazil between 1996 and 2012, obtained from the Hospital Information System of the Ministry of Health. We estimated the number of unsafe abortions stratified by place of residence, using indirect estimate techniques. The following indicators were calculated: ratio of unsafe abortions/100 live births and rate of unsafe abortion/1,000 women of childbearing age. We analyzed temporal trends through polynomial regression and spatial distribution using municipalities as the unit of analysis. RESULTS In the study period, a total of 4,007,327 hospital admissions due to abortions were recorded in Brazil. We estimated a total of 16,905,911 unsafe abortions in the country, with an annual mean of 994,465 abortions (mean unsafe abortion rate: 17.0 abortions/1,000 women of childbearing age; ratio of unsafe abortions: 33.2/100 live births). Unsafe abortion presented a declining trend at national level (R2: 94.0%, p < 0.001), with unequal patterns between regions. There was a significant reduction of unsafe abortion in the Northeast (R2: 93.0%, p < 0.001), Southeast (R2: 92.0%...

CONTEXT AND OBJECTIVE: Recurrent spontaneous abortion (RSA) is defined as three or more consecutive pregnancy losses before 20 weeks and is associated with several etiological factors related to genetics, anatomy, hormones, infections and immunology, for example. Many cases of RSA remain unclear. New factors or their associations may influence gestational results. The aim was to identify possible single or associated causes of RSA that could predict gestational prognosis for women undergoing investigation and treatment. DESIGN AND SETTING: Case-control study, at the Recurrent Abortion Outpatient Clinic, Department of Obstetrics and Gynecology School of Medicine, Universidade Estadual de Campinas (Unicamp). METHODS: Two hundred and forty-six medical records of women with RSA seen at the Recurrent Abortion Outpatient Clinic, Department of Obstetrics and Gynecology School of Medicine, Universidade Estadual de Campinas (Unicamp), between 1994 and 2003, were evaluated. Data on age, obstetric history, possible etiological factors, treatment and pregnancy outcomes were evaluated. Statistical analysis was performed using odds ratios (OR), logistic regression analysis and decision trees. RESULTS: Two hundred and twenty-nine women were included in the study. The most frequently found etiological factors were immunological...

Studies were conducted on pollination and patterns of fruit and seed production to assess the potential factors causing high fruit and seed abortion in Dahlstedtia pentaphylla (Leguminosae) through analyses of relationships between flower position in the inflorescence and ovules and seeds within ovaries and fruits, and flower, fruit and seed abortion. No differences were found in pollination and fruit set as a function of inflorescence position. There was no relationship, neither between degenerating ovules and their position within the ovary, nor between developing seed and fruit position. Maternal resource limitation related to fruits and embryos, due to the high cost of fruit production and seed maturation, was one of the factors that led to a high abortion rate in D. pentaphylla.

OBJECTIVE: To assess interregional differences in the utilization of abortion services in Ontario from 1985 to 1992. DESIGN: Retrospective analysis of provincial therapeutic abortion database. SETTING: All hospitals conducting abortions between 1985 and 1992 and all free-standing abortion clinics conducting abortions between 1990 and 1992. POPULATION: All women in Ontario aged 15 to 44 years who underwent a therapeutic abortion in Ontario during the study period. OUTCOME MEASURES: Utilization of abortion services by county and age-specific abortion rates by county of residence. RESULTS: From 1985 to 1989, when only hospital data were gathered, the mean therapeutic abortion rate increased by 11.2%. From 1990 to 1992, when data from hospitals and free-standing clinics were collected, the mean rate increased by 26.5%. Logistic regression analysis showed significant variation in the age-standardized abortion rates between counties in each study year (p < 0.0001). The counties with age-standardized rates below the 25th percentile had the highest proportions of women who sought abortion services outside their county of residence; in some of these counties no abortions were performed in local facilities. CONCLUSION: There are interregional variations in the utilization of abortion services in Ontario. These disparities raise questions about the accessibility of abortion services and need to be further investigated.

BACKGROUND. The impact of the Minnesota Parental Notification Law on abortion and birth was examined. METHODS. Using linear models, outcome parameters were compared before and after enactment of the law. Time by age group interactions also were examined. RESULTS. The pre-enactment to post-enactment change in the Minnesota abortion rate reflected a greater decline for minors (less than or equal to 17 years old) than for 18-19 year-olds (who were not under the law). An increase in abortion rate occurred for women ages 20-44. The law appeared to have had no impact on birth rate in minors. Following the enactment of the law, the rate of early abortions (less than or equal to 12 weeks) declined among minors more than the rate of late abortions (greater than 12 weeks). This resulted in a pre-enactment to post-enactment increase in the ratio of late-to-early abortions among minors. CONCLUSIONS. These data suggest that parental notification facilitated pregnancy avoidance in 15-17 year-old Minnesota women. Abortion rates declined unexpectedly while birth rates continued to decline in accordance with a long-term trend.

We report a family ascertained for molecular diagnosis of muscular dystrophy in a young girl, in which preferential activation (> or = 95% of cells) of the paternal X chromosome was seen in both the proband and her mother. To determine the molecular basis for skewed X inactivation, we studied X-inactivation patterns in peripheral blood and/or oral mucosal cells from 50 members of this family and from a cohort of normal females. We found excellent concordance between X-inactivation patterns in blood and oral mucosal cell nuclei in all females. Of the 50 female pedigree members studied, 16 showed preferential use (> or = 95% cells) of the paternal X chromosome; none of 62 randomly selected females showed similarly skewed X inactivation was maternally inherited in this family. A linkage study using the molecular trait of skewed X inactivation as the scored phenotype localized this trait to Xq28 (DXS1108; maximum LOD score [Zmax] = 4.34, recombination fraction [theta] = 0). Both genotyping of additional markers and FISH of a YAC probe in Xq28 showed a deletion spanning from intron 22 of the factor VIII gene to DXS115-3. This deletion completely cosegregated with the trait (Zmax = 6.92, theta = 0). Comparison of clinical findings between affected and unaffected females in the 50-member pedigree showed a statistically significant increase in spontaneous-abortion rate in the females carrying the trait (P < .02). To our knowledge...

The report consists of three parts: global trends in fertility, contraceptive use and unintended pregnancies; studies of two regions (Africa and Eastern Europe/Central Asia) and two countries (Nigeria and Kazakhstan) on the costs of fertility regulation behaviors and provider attitudes towards contraceptive use. Fertility levels have declined steadily over the last three decades but the pace of decline varies among regions. Countries that have achieved a high level of contraceptive use have reached a lower fertility level. A gap continues to exist between actual and desired family size, resulting in unintended pregnancies. More than one-third of the pregnancies that occur are unintended and one in five pregnancies ends in induced abortion. Almost half of all induced abortions are unsafe, and the proportion of all abortions that are unsafe have increased during the last decade. Sixty-six percent of unintended pregnancies occur among women who are not using any method of contraception. Investing in quality family planning programs is a cost-effective way to address unmet need for contraception and reduce the risks of unsafe abortion...

BACKGROUND: To identify an effective misoprostol-only regimen for the termination of second trimester pregnancy, we compared sublingual and vaginal administration of multiple doses of misoprostol in a randomized, placebo-controlled equivalence trial. METHODS: Six hundred and eighty-one healthy pregnant women requesting medical abortion at 13-20 weeks' gestation were randomly assigned within 11 gynaecological centres in seven countries into two treatment groups: 400 microg of misoprostol administered either sublingually or vaginally every 3 h up to five doses, followed by sublingual administration of 400 microg misoprostol every 3 h up to five doses if abortion had not occurred at 24 h after the start of treatment. We chose 10% as the margin of equivalence. The primary end-point was the efficacy of the treatments to terminate pregnancy in 24 h. Successful abortion within 48 h was also considered as an outcome along with the induction-to-abortion-interval, side effects and women's perceptions on these treatments. RESULTS: At 24 h, the success (complete or incomplete abortion) rate was 85.9% in the vaginal administration group and 79.8% in the sublingual group (difference: 6.1%, 95% CI: 0.5 to 11.8). Thus, equivalence could not be concluded overall; the difference...

This report presents the findings of an exploratory study conducted in poor areas of three provinces in northern Argentina (Misiones, Salta, and Santiago del Estero). The study comprised a random (cluster) sample of three hundred households of women in reproductive age with at least one child. Focus groups (13) and in-depth interviews with key informants (health providers, educators, religious, and community leaders) were conducted to validate quantitative data and to explore issues such as gender roles, domestic violence, abortion, and contraception. The study aimed at contributing to a better understanding of reproductive health issues, quality of life, and rural poverty--primarily as it affects women--and providing policy recommendations for addressing reproductive health issues in rural poverty alleviation strategies. The study also explored, albeit on a limited basis, men's perceptions and behavior related to reproductive health. The principal findings of this study focus on gathering reliable data for decisionmaking especially at the sub-national levels; controlling family size as it has a direct impact on women's income-generating capacity and quality of life; developing the political will to promote and implement comprehensive reproductive health programs; increasing public awareness of reproductive health; and analyzing factors in the underutilization of health services and contraceptives.

This study examines fertility regulation in Kazakhstan, with dual emphases on providers' attitudes toward abortion and the public financial costs of abortion provision. Though abortion incidence declined sharply in the 1990s in Eastern European countries and in the former Soviet republics, it stagnated at relatively high levels in the early 2000s, accounting for a substantial proportion of gynecological morbidity and maternal mortality. Limited literature is available on the role of health service providers' attitudes that may encourage or discourage abortion culture. Additionally, most studies examine abortion incidence from the perspective of its impact on women's health, while the issue of the public financial burden imposed by the provision of services for "avoidable" abortions remains unexplored. This study sheds lights on these two areas by conducting a two-part field survey in Kazakhstan. Three-stage stratified sampling was used to select 126 providers from 52 health facilities from four oblasts and two major cities (Almaty and Astana) at different administrative levels to assess providers' attitudes and perceptions; and to analyze the public costs of providing abortion and family planning services. Findings from the provider survey suggest that providers' biases towards certain contraceptive methods-partly attributable to their lack of training in alternative methods-lead them to limit the choice of contraceptive methods on offer...

This paper examines the population changes and the related causative factors, namely fertility, mortality and international migration in Sri Lanka. During the past decades, the total size, as well as the age and sex structure of the population, was exposed to irreversible changes. The age structure transition has produced a demographic bonus conducive for an economic takeoff. During this period, the proportion of people of working age (15-59) is larger than the fraction in the dependent age categories. The paper includes a sector analysis of the employed population in the agriculture, industry and service sectors to identify the growth sectors of the economy and to reveal the potential patterns and levels of utilization of the demographic bonus. Finally, the social safety net implications of the emerging population, such as the dependency burden, aging, disability and the disintegration of traditional family system in Sri Lanka are examined. Sri Lanka's population has grown to 20 million in 2010, an almost eight-fold increase since the census of 1871. The population doubled 54 years after the first census (1925)...

This article presents the results of a study in the city of São Paulo, Brazil, aimed at estimating the frequency of induced abortion among women 15 to 49 years of age. The objective was to characterize the occurrence of induced abortion by comparing the ideal number of children, age, and contraceptive use between married and single women. Based on random sampling, 1,749 interviews were held, including 764 married women, 658 single women, and 327 with other marital status. The analysis included: mean number of abortions per woman by analysis of variance and proportions of abortions and pregnancy, using the chi-square test. The mean abortion rate for married women (45 per thousand) did not differ statistically from that of single women. However, the pregnancy rate was much lower in single women, and when single women became pregnant they used abortion more frequently; while fewer than 2% of pregnancies in married women ended in induced abortions, among single women the abortion rate exceeded 18%. Therefore, the priority in the reproductive health field should be to invest in the supply and dissemination of appropriate contraceptive methods for women's early sexually active life.; Apresenta-se uma pesquisa realizada na cidade de São Paulo...

OBJECTIVE: If properly trained, medical students could become future opinion leaders in health policy and could help the public to understand the consequences of unwanted pregnancies and of abortions. The objective of this study was to analyze the frequency of unwanted pregnancies and induced abortions that had occurred among women who were first-year medical students at a major public university in Mexico City and to compare the experiences of those women with the experiences of the general population of Mexican females aged 15 to 24. METHODS: In 1998 we administered a cross-sectional survey to all the first-year medical students at the National Autonomous University of Mexico, which is the largest university in Latin America. For this study we analyzed 549 surveys completed by female students. RESULTS: Out of the 549 women, 120 of them (22%) had been sexually active at some point. Among those 120 sexually active students, 100 of them (83%) had used a contraceptive method at some time, and 19 of the 120 (16%) had been pregnant. Of those 19 women who had been pregnant, 10 of them had had an illegal induced abortion (in Mexico, abortions are illegal except under a small number of extenuating circumstances). The reported abortion rate among the female medical students...

OBJECTIVE To analyze temporal trends and distribution patterns of unsafe abortion in Brazil. METHODS Ecological study based on records of hospital admissions of women due to abortion in Brazil between 1996 and 2012, obtained from the Hospital Information System of the Ministry of Health. We estimated the number of unsafe abortions stratified by place of residence, using indirect estimate techniques. The following indicators were calculated: ratio of unsafe abortions/100 live births and rate of unsafe abortion/1,000 women of childbearing age. We analyzed temporal trends through polynomial regression and spatial distribution using municipalities as the unit of analysis. RESULTS In the study period, a total of 4,007,327 hospital admissions due to abortions were recorded in Brazil. We estimated a total of 16,905,911 unsafe abortions in the country, with an annual mean of 994,465 abortions (mean unsafe abortion rate: 17.0 abortions/1,000 women of childbearing age; ratio of unsafe abortions: 33.2/100 live births). Unsafe abortion presented a declining trend at national level (R2: 94.0%, p < 0.001), with unequal patterns between regions. There was a significant reduction of unsafe abortion in the Northeast (R2: 93.0%, p < 0.001), Southeast (R2: 92.0%...
