    Preterm birth is a leading cause of neonatal morbidity and mortality. It is a major goal in obstetrics to lower the incidence of spontaneous preterm birth (SPB) and related neonatal morbidity and mortality. One of the principal objectives is to discover early markers that would allow us to identify

    BACKGROUND: Spontaneous abortion is the most commonly observed adverse pregnancy outcome. The angiogenic factors soluble Fms-like kinase 1 and placental growth factor are critical for normal pregnancy and may be associated to spontaneous abortion. OBJECTIVE: We investigated the association between...... maternal serum concentrations of soluble Fms-like kinase 1 and placental growth factor, and subsequent spontaneous abortion. STUDY DESIGN: In the prospective observational Odense Child Cohort, 1676 pregnant women donated serum in early pregnancy, gestational week ..., interquartile range 71-103). Concentrations of soluble Fms-like kinase 1 and placental growth factor were determined with novel automated assays. Spontaneous abortion was defined as complete or incomplete spontaneous abortion, missed abortion, or blighted ovum

    To examine whether a first or second trimester induced abortion with misoprostol influences the risk of late abortion or preterm delivery in subsequent pregnancies. Case-control study in a teaching hospital from January 2005 to June 2006. The cases had singleton pregnancies delivered at 16-36 weeks of gestation after spontaneous late abortions, preterm labor or preterm premature rupture of membrane, or induction of labor for preterm premature rupture of membrane before 37 weeks. The control group was composed of the two consecutive spontaneous singleton deliveries at >or=37 weeks of gestation after each new case (ratio 2/1). The principal outcome measure was late abortion or preterm delivery. The association between late abortion or preterm delivery and a previous induced abortion with misoprostol was first assessed with the Cochran-Mantel-Haenszel chi-square test. Conditional logistic regression models adapted for clustered data were then further used to quantify the effect size, measured by estimated odds ratios (ORs) with their 95% confidence intervals (95% CI). The study included 245 cases and 490 controls. There was no significant difference in mean maternal age, number of pregnancies, parity, smoking, or history of first trimester miscarriage between cases and controls. However, a history of late abortion or previous preterm delivery was significantly more frequent among cases than controls. Forty (16.3%) cases and 56 (11.5%) controls had a history of cervical ripening with misoprostol before vacuum curettage or evacuation, or of medical abortion by misoprostol alone or with mifepristone (OR 1.51, 95% CI: 0.95-2.39; p=0.08). After adjustment for maternal age and number of pregnancies with a multivariable conditional regression model, the adjusted OR was estimated at 1.33 (95% CI: 0.81-2.17; p=0.25). Despite the need for prudence, these results provide some reassurance that induced abortion with misoprostol during the first or second trimester of pregnancy is

    Many people believe human fetuses have the same moral status as adult human persons, that it is wrong to allow harm to befall things with this moral status, and thus voluntary, induced abortion is seriously morally wrong. Recently, many prochoice theorists have argued that this antiabortion stance is inconsistent; approximately 60% of human fetuses die from spontaneous abortion, far more than die from induced abortion, so if antiabortion theorists really believe that human fetuses have significant moral status, they have strong moral obligations to oppose spontaneous abortion. Yet, few antiabortion theorists devote any effort to doing so. Many prochoice theorists argue that to resolve this inconsistency, antiabortion theorists should abandon their opposition to induced abortion. Here, I argue that those who do not abandon their opposition to induced abortion but continue to neglect spontaneous abortion act immorally. Aristotle argues that moral responsibility requires both control and awareness; I argue that once an antiabortion theorist becomes aware of the frequency of spontaneous abortion, they have a strong moral obligation to redirect their efforts towards combating spontaneous abortion; failure to do so is morally monstrous. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Abortion is associated with moderate to high risk of psychological problems such as depression, use of alcohol or marijuana, anxiety, depression and suicidal behaviours. The increased risk of depression after spontaneous abortion in Asian populations has not been clearly established. Only a few studies have explored the relationship between grief and depression after abortion. A study was conducted to assess the prevalence and risk factors of depressive disorder and complicated grief among women 6-10 weeks after spontaneous abortion and compare the risk of depression with pregnant women attending an antenatal clinic. Spontaneous abortion group consisted of women diagnosed with spontaneous abortion by a Consultant Obstetrician. Women with confirmed or suspected induced abortion were excluded. The comparison group consisted of randomly selected pregnant, females attending the antenatal clinics of the two hospitals. Diagnosis of depressive disorder was made according to ICD-10 clinical criteria based on a structured clinical interview. This assessment was conducted in both groups. The severity of depressive symptoms were assessed using the Patients Health Questionnaire (PHQ-9). Grief was assessed using the Perinatal Grief Scale which was administered to the women who had experienced spontaneous abortion. The sample consisted of 137 women in each group. The spontaneous abortion group (mean age 30.39 years (SD = 6.38) were significantly older than the comparison group (mean age 28.79 years (SD = 6.26)). There were more females with ≥10 years of education in the spontaneous abortion group (n = 54; SD = 39.4) compared to the comparison group (n = 37; SD = 27.0). The prevalence of depression in the spontaneous abortion group was 18.6 % (95 CI, 11.51-25.77). The prevalence of depression in the comparison group was 9.5 % (95 CI, 4.52-14.46). Of the 64 women fulfilling criteria for grief, 17 (26.6 %) also fulfilled criteria for a depressive episode. The relative risk of

    Full Text Available BACKGROUND: Preterm birth rate is increasing and is currently a worldwide concern. The purpose of this study was to estimate the prevalence of preterm birth in a sample of health facilities in Brazil and to identify the main risk factors associated with spontaneous preterm births. METHODS AND FINDINGS: This was a multicentre cross sectional study on preterm births in 20 referral obstetric hospitals with a case-control component to identify factors associated with spontaneous preterm birth. Surveillance was implemented at all centres to identify preterm births. For eligible consenting women, data were collected through a post-delivery questionnaire completed with information from all mother-newborn medical records until death or discharge or at a maximum of 60 days post-delivery, whichever came first. The risk of spontaneous preterm birth was estimated with OR and 95%CI for several predictors. A non-conditional logistic regression analysis was then performed to identify independently associated factors. The overall prevalence of preterm birth was 12.3%. Among them, 64.6% were spontaneous and 35.4% therapeutic. In the case-control component, 2,682 spontaneous preterm births were compared to a sample of 1,146 term births. Multivariate analyses identified the following as risk factors for spontaneous preterm birth among women with at least one previous birth: a previous preterm birth (ORadj = 3.19, 2.30-4.43, multiple pregnancy (ORadj = 29.06, 8.43-100.2, cervical insufficiency (ORadj = 2.93, 1.07-8.05, foetal malformation (ORadj = 2.63, 1.43-4.85, polyhydramnios (ORadj = 2.30, 1.17-4.54, vaginal bleeding (ORadj = 2.16, 1.50-3.11, and previous abortion (ORadj = 1.39, 1.08-1.78. High BMI (ORadj = 0.94, 0.91-0.97 and weight gain during gestation (ORadj = 0.92, 0.89-0.95 were found to be protective factors. CONCLUSIONS: The preterm birth rate in these health facilities in Brazil is high and spontaneous preterm births

    To investigate fetomaternal microchimerism in women with induced abortion or spontaneous pregnancy loss. Peripheral blood samples were obtained from 76 healthy women who underwent dilation and curettage in the first trimester but had never had an abortion or male delivery before. Samples were collected at three time points: just before, 7 days after, and 30 days after abortion. Y chromosome-specific, nested polymerase chain reaction targeting the sex-determining region of Y (SRY) was used to test DNA extracted from buffy coat cells. DNA was also extracted from the chorion to determine sex. The sensitivity of our assay allowed detection of approximately one male cell in 100,000 female cells. Thirty-six male and 40 female chorions were obtained. Male DNA was found in 52.8% of women who had a male chorion before abortion, decreasing to 5.6% at 7 days after abortion. At 30 days after abortion, no male DNA was detected. Male DNA was never detected at any point from women with a female chorion. Fetal cells in the maternal circulation are undetectable 30 days after induced abortion or spontaneous pregnancy loss. Fetal cells may be harbored in maternal organs.

    Summary Preterm birth is the leading cause of perinatal morbidity and mortality worldwide, and its prevention is an important healthcare priority. Preterm parturition is one of the ‘great obstetrical syndromes’ and is caused by multiple etiologies. One of the mechanisms of disease is the untimely decline in progesterone action, which can be manifested by a sonographic short cervix in the midtrimester. The detection of a short cervix in the midtrimester is a powerful risk factor for preterm delivery. Vaginal progesterone can reduce the rate of preterm delivery by 45%, and the rate of neonatal morbidity (admission to neonatal intensive care unit, respiratory distress syndrome, need for mechanical ventilation, etc.). To prevent one case of spontaneous preterm birth birth in women with a short cervix both with and without a prior history of preterm birth. In patients with a prior history of preterm birth, vaginal progesterone is as effective as cervical cerclage to prevent preterm delivery. 17α-Hydroxyprogesterone caproate has not been shown to be effective in reducing the rate of spontaneous preterm birth in women with a short cervix.

    Full Text Available Background: Spontaneous abortion is the most common adverse pregnancy outcome. We aimed to investigate a possible link between nutrient deficiencies and the risk of spontaneous abortion. Materials and Methods: This case-control study included the case group (n=331 experiencing a spontaneous abortion before 14 weeks of pregnancy and the control group (n=331 who were healthy pregnant women over 14 weeks of pregnancy. The participants filled out Food Frequency Questionnaire (FFQ, in which they reported their frequency of consumption for a given serving of each food item during the past three months, on a daily, weekly or monthly basis. The reported frequency for each food item was converted to a daily intake. Then, consumption of nutrients was compared between the two groups. Results: There are significant differences between the two groups regarding consumed servings/day of vegetables, bread and cereal, meat, poultry, fish, eggs, beans, fats, oils and dairy products (P=0.012, P<0.001, P=0.004, P<0.001, P=0.019, respectively. There are significant differences between the two groups in all micronutrient including folic acid, iron, vitamin C, vitamin B6, vitamin B12 and zinc (P<0.001. Conclusion: Poor nutrientions may be correlated with increased risk of spontaneous abortion

    To determine if bacterial vaginosis is a marker for risk of spontaneous preterm delivery and if its detection and treatment can reduce this risk. Consultation of the database Pubmed/Medline, Science Direct, and international guidelines of medical societies. Bacterial vaginosis (BV) is a dysbiosis resulting in an imbalance in the vaginal flora through the multiplication of anaerobic bacteria and jointly of a disappearance of well-known protective Lactobacilli. His diagnosis is based on clinical Amsel criteria and/or a Gram stain with establishment of the Nugent score. The prevalence of the BV extraordinarily varies according to ethnic and/or geographical origin (4-58 %), in France, it is close to 7 % in the first trimester of pregnancy (EL2). The link between BV and spontaneous premature delivery is low with an odds ratio between 1.5 and 2 in the most recent studies (EL3). Metronidazole or clindamycin is effective to treat BV (EL3). It is recommended to prescribe one of these antibiotics in the case of symptomatic BV (Professional Consensus). The testing associated with the treatment of BV in the global population showed no benefit in the prevention of the risk of spontaneous preterm delivery (EL2). Concerning low-risk asymptomatic population (defined by the absence of antecedent of premature delivery), it has been failed profit to track and treat the BV in the prevention of the risk of spontaneous preterm delivery (EL1). Concerning the high-risk population (defined by a history of preterm delivery), it has been failed profit to track and treat the VB in the prevention of the risk of spontaneous preterm delivery (EL3). However, in the sub population of patients with a history of preterm delivery occurred in a context of materno-fetal bacterial infection, there may be a benefit to detect and treat early and systematically genital infection, and in particular the BV (Professional Consensus).

    To determine whether interpregnancy interval after the first spontaneous abortion has an effect on reproductive performance of women in their next pregnancy. A prospective cohort study was conducted on 4,619 women with history of spontaneous abortion in their first pregnancy. Of them 2,422 (52.4 %) conceived within 6 months of the miscarriage (group A) and 2,197 47.6 % after 12 months (group B). The primary outcome was abortion, live birth, termination, or ectopic pregnancy in the next pregnancy. Secondary outcomes were preterm delivery, low birth weight infants, caesarean section rate and occurrence of preeclampsia, placental abruption and induced labour in the second pregnancy. Women who conceived again within 6 months were less likely to have another abortion, termination, or ectopic pregnancy compared with women with interpregnancy interval more than 12 months. Women with an interpregnancy interval more than 12 months were less likely to have live birth in the second pregnancy and more likely to have a caesarean section, preterm delivery, or infant of low birth weight compared with women who conceived again within 6 months. Women who conceive within 6 months after their first spontaneous abortion have better reproductive outcomes and the lowest complication rates in their subsequent pregnancy.

    Full Text Available Numerous studies have demonstrated that therapeutic termination of pregnancy (abortion is associated with an increased risk of subsequent preterm birth. However, the literature is inconsistent, and methods of abortion have changed dramatically over the last 30 years. We hypothesized that the association between previous abortion and the risk of preterm first birth changed in Scotland between 1 January 1980 and 31 December 2008.We studied linked Scottish national databases of births and perinatal deaths. We analysed the risk of preterm birth in relation to the number of previous abortions in 732,719 first births (≥24 wk, adjusting for maternal characteristics. The risk (adjusted odds ratio [95% CI] of preterm birth was modelled using logistic regression, and associations were expressed for a one-unit increase in the number of previous abortions. Previous abortion was associated with an increased risk of preterm birth (1.12 [1.09-1.16]. When analysed by year of delivery, the association was strongest in 1980-1983 (1.32 [1.21-1.43], progressively declined between 1984 and 1999, and was no longer apparent in 2000-2003 (0.98 [0.91-1.05] or 2004-2008 (1.02 [0.95-1.09]. A statistical test for interaction between previous abortion and year was highly statistically significant (p<0.001. Analysis of data for abortions among nulliparous women in Scotland 1992-2008 demonstrated that the proportion that were surgical without use of cervical pre-treatment decreased from 31% to 0.4%, and that the proportion of medical abortions increased from 18% to 68%.Previous abortion was a risk factor for spontaneous preterm birth in Scotland in the 1980s and 1990s, but the association progressively weakened and disappeared altogether by 2000. These changes were paralleled by increasing use of medical abortion and cervical pre-treatment prior to surgical abortion. Although it is plausible that the two trends were related, we could not test this directly as the data on

    To determine prenatal methods to predict and prevent spontaneous preterm birth in asymptomatic twin pregnancies. Articles were searched using PubMed, Embase and Cochrane library. Uterine activity monitoring and bacterial vaginosis screening are not useful to predict preterm birth (EL2 and EL3 respectively). Current literature data are contradictory and insufficient to determine whether fetal fibronectin and digital cervical assessment are predictors of preterm birth. History of preterm birth (EL4), and cervical length measurement by transvaginal ultrasonography (EL2) predict preterm birth. Nevertheless, there are no intervention studies that have evaluated cervical length measurement in the prevention of preterm birth. Hospital bedrest, prophylactic tocolytic and progesterone therapy, and prophylactic cervical cerclage in patients with or without short cervix have not been shown to be effective in preventing preterm birth. Prenatal methods to prevent spontaneous preterm birth in asymptomatic twin pregnancies are currently very limited. Copyright © 2009 Elsevier Masson SAS. All rights reserved.

    Does the incidence of spontaneous abortion correlate positively over conception cohorts with the incidence of non-clinically indicated induced abortion as predicted by shared risk aversion? We find that the number of spontaneous and non-clinically indicated induced abortions correlates in conception cohorts, suggesting that risk aversion affects both the conscious and non-conscious mechanisms that control parturition. Much literature speculates that natural selection conserved risk aversion because the trait enhanced Darwinian fitness. Risk aversion, moreover, supposedly influences all decisions including those that individuals can and cannot report making. We argue that these circumstances, if real, would manifest in conscious and non-conscious decisions to invest in prospective offspring, and therefore affect incidence of induced and spontaneous abortion over time. Using data from Denmark, we test the hypothesis that monthly conception cohorts yielding unexpectedly many non-clinically indicated induced abortions also yield unexpectedly many spontaneous abortions. The 180 month test period (January 1995 through December 2009), yielded 1 351 800 gestations including 156 780 spontaneous as well as 233 280 induced abortions 9100 of which were clinically indicated. We use Box-Jenkins transfer functions to adjust the incidence of spontaneous and non-clinically indicated induced abortions for autocorrelation (including seasonality), cohort size, and fetal as well as gestational anomalies over the 180-month test period. We use cross-correlation to test our hypothesized association. We find a positive association between spontaneous and non-clinically indicated induced abortions. This suggests, consistent with our theory, that mothers of conception cohorts that yielded more spontaneous abortions than expected opted more frequently than expected for non-clinically indicated induced abortion. Limitations of our work include that even the world's best registration system

    Full Text Available Context: Bacterial vaginosis (BV is related to the increased risk of miscarriage, preterm labor, and postpartum endometritis. Aims: The aim of this study was to evaluate the association between BV and the history of spontaneous abortion and recurrent pregnancy losses. We also examined periods of gestation, including the first and second trimester miscarriages. Materials and Methods: The study population consisted of 200 fertile women. Sixty one (30.5% of 200 women had the history of a spontaneous abortion in the last six months (N = 30 and at least three recurrent pregnancy losses (N = 31. BV was diagnosed either by using Papanicolaou staining, Gram staining, or by culturing with BV-associated bacteria, Gardnerella vaginalis. Results: The presence of BV was statistically associated with the history of a spontaneous abortion in the last 6 months (P 0.05. These women were also evaluated in view of periods of gestation. Forty-seven (77% of 61 women had first trimester miscarriage (≤12 weeks and 14 (23% of 61 women had second trimester miscarriage (>12 weeks. There was a statistically significant relationship between BV and second trimester miscarriage (P 0.05. Conclusion: BV may contribute to spontaneous abortion and second trimester miscarriage.

    The relationship between abortion and uterine fibroids has received little attention. The aim of the present study was to explore the association between number of induced and spontaneous abortions and the risk of uterine fibroids in middle-aged and older Chinese women. A total of 14,595 retired female employees from the Dongfeng-Tongji cohort study were included in our analysis. Information on induced and spontaneous abortions was collected by trained interviewers through face-to-face interviews. Diagnosis of uterine fibroids was based on ultrasound or self-reported physician diagnosis of uterine fibroids. Logistic regression models were used to explore the associations between number of induced and spontaneous abortions and the risk of uterine fibroids. The prevalence of uterine fibroids was 15.1% among all participants. Higher number of induced abortions was associated with an increased risk of uterine fibroids (1 induced abortion: odds ratios [ORs] = 1.32, 95% confidence interval [CI] 1.18-1.48; 2 induced abortions: OR = 1.45, 95% CI 1.28-1.64; and ≥3 induced abortions: OR = 1.62, 95% CI 1.39-1.90). Compared with women without induced abortion, ORs for women with 1, 2, and ≥3 were 1.17 (95% CI 1.03-1.32), 1.21 (95% CI 1.06-1.39), and 1.36 (95% CI 1.15-1.61), respectively, after adjustment for potential confounders. No association was observed between the number of spontaneous abortions and the risk of uterine fibroids. The findings of this study showed that induced abortion may be an independent risk factor for uterine fibroids in middle-aged and older Chinese women.

    The insertion of male perspective in reproductive health is an international recommendation. The aim of this research was to know the men's feelings related to the abortion shared with their partners. The narrative analysis was the research method. The narratives of seventeen men were analysed. The spontaneous abortion related feelings were the loss related anguish and, the provoked abortion, the culpability related feelings and its consequences. Men who share the abortion experience with their partners require sensibility and professionals involvement. Their main care demands were related to the desire of favorable reception, to get emotional support as well as a whole and correct information about the process.

    This study aimed to evaluate the correlation between ambient concentrations of air pollutants and first-trimester spontaneous abortion. This was a retrospective case–control study, which was conducted on 296 women from June 2010 to February 2011 in Tehran, Iran. Cases were 148 women who experienced a spontaneous abortion before 14 weeks of gestation while the controls were 148 pregnant women after 14 weeks of gestation and groups were matched on sociodemographics and obstetrics characteristics. The samples were recruited randomly from 10 hospitals. In total, pollutants concentrations were collected at 29 stations hourly throughout the study area. We estimated the mean exposure for each participant and investigated the association between spontaneous abortion and ambient pollutants. Findings demonstrated that the average of ambient air pollutants in the cases was significantly higher than in the controls (P abortion in the areas with higher concentrations of CO, NO₂, O₃ and PM₁₀ were 1.98, 0.96, 0.94 and 1.01, respectively (P abortion (P > 0.05). Our findings suggest that pregnant women exposed to ambient air pollutants may be at increased risk of spontaneous abortion. Confirmation by further research is needed.

    Despite having one of the most liberal abortion laws in sub-Saharan Africa, complications from induced abortion are the second leading cause of maternal mortality in Ghana. The sample is composed of patients with pregnancy termination complications in Ghana between June and July 2008. The majority of patients report having had a spontaneous abortion (75%; n=439), while 17% (n=100) and 8% (n=46) report having had an induced abortion or an ectopic pregnancy, respectively. Factors associated with women in each of the three groups were explored using multinomial logistic regression. When compared to women with spontaneous abortions, women with induced abortions were younger, poorer, more likely to report no religious affiliation, less likely to be married, more likely to report making the household decisions and more likely to fail to disclose this pregnancy to their partners. Within the induced abortion subsample, failure to disclose the most recent pregnancy was associated with already having children and autonomous household decision making. Identifying the individual and relationship characteristics of induced abortion patients is the first step toward targeted policies and programs aimed at reducing unsafe abortion in Ghana.

    Spontaneous abortion is one of the most important complications of pregnancy with short and long adverse psychological effects on women. This study assesses the implications of a spontaneous abortion history has on women's psychiatric symptoms and pregnancy distress in subsequent pregnancy less than one years after spontaneous abortion. A case-control study was conducted on pregnant women of Babol city from September 2014 to May 2015. In this study, 100 pregnant women with spontaneous abortion history during a year ago and 100 pregnant women without spontaneous abortion history were enrolled. All the participants in two groups completed the Symptom Checklist-90-Revised (SCL-90-R), and pregnancy Distress Questionnaire (PDQ). Women with spontaneous abortion history had significantly higher mean of many subscales of SCL-90 (depression, anxiety, somatization, obsessive-compulsiveness, interpersonal sensitivity, psychoticism, hostility, paranoid, and Global Severity Index) more than women without spontaneous abortion history. Also, women with spontaneous abortion history had significantly higher mean of two subscales of PDQ concerns about birth and the baby, concerns about emotions and relationships) and total PDQ more than women without spontaneous abortion history. Pregnant women with less than a year after spontaneous abortion history are at risk of psychiatric symptoms and pregnancy distress more than controls. This study supports those implications for planning the post spontaneous abortion psychological care for women, especially women who wanted to be pregnant during 12 month after spontaneous abortion.

    Preterm delivery represents a substantial problem in perinatal medicine worldwide. Current knowledge on potential influences of probiotics in food on pregnancy complications caused by microbes is limited. We hypothesized that intake of food with probiotics might reduce pregnancy complications caused by pathogenic microorganisms and, through this, reduce the risk of spontaneous preterm delivery. This study was performed in the Norwegian Mother and Child Cohort on the basis of answers to a food-frequency questionnaire. We studied intake of milk-based products containing probiotic lactobacilli and spontaneous preterm delivery by using a prospective cohort study design (n = 950 cases and 17,938 controls) for the pregnancy outcome of spontaneous preterm delivery (delivery were associated with any intake of milk-based probiotic products in an adjusted model [odds ratio (OR): 0.857; 95% CI: 0.741, 0.992]. By categorizing intake into none, low, and high intakes of the milk-based probiotic products, a significant association was observed for high intake (OR: 0.820; 95% CI: 0.681, 0.986). Women who reported habitual intake of probiotic dairy products had a reduced risk of spontaneous preterm delivery.

    Although antibiotics are widely used during pregnancy, evidence regarding their fetal safety remains limited. Our aim was to quantify the association between antibiotic exposure during pregnancy and risk of spontaneous abortion. We conducted a nested case-control study within the Quebec Pregnancy Cohort (1998-2009). We excluded planned abortions and pregnancies exposed to fetotoxic drugs. Spontaneous abortion was defined as having a diagnosis or procedure related to spontaneous abortion before the 20th week of pregnancy. The index date was defined as the calendar date of the spontaneous abortion. Ten controls per case were randomly selected and matched by gestational age and year of pregnancy. Use of antibiotics was defined by filled prescriptions between the first day of gestation and the index date and was compared with (a) non-exposure and (b) exposure to penicillins or cephalosporins. We studied type of antibiotics separately using the same comparator groups. After adjustment for potential confounders, use of azithromycin (adjusted odds ratio [OR] 1.65, 95% confidence interval [CI] 1.34-2.02; 110 exposed cases), clarithromycin (adjusted OR 2.35, 95% CI 1.90-2.91; 111 exposed cases), metronidazole (adjusted OR 1.70, 95% CI 1.27-2.26; 53 exposed cases), sulfonamides (adjusted OR 2.01, 95% CI 1.36-2.97; 30 exposed cases), tetracyclines (adjusted OR 2.59, 95% CI 1.97-3.41; 67 exposed cases) and quinolones (adjusted OR 2.72, 95% CI 2.27-3.27; 160 exposed cases) was associated with an increased risk of spontaneous abortion. Similar results were found when we used penicillins or cephalosporins as the comparator group. After adjustment for potential confounders, use of macro-lides (excluding erythromycin), quinolones, tetracyclines, sulfonamides and metronidazole during early pregnancy was associated with an increased risk of spontaneous abortion. Our findings may be of use to policy-makers to update guidelines for the treatment of infections during pregnancy. © 2017

    Evidence from family and twin-based studies provide strong support for a significant contribution of maternal and fetal genetics to the timing of parturition and spontaneous preterm birth. However, there has been only modest success in the discovery of genes predisposing to preterm birth, despite increasing sophistication of genetic and genomic technology. In contrast, DNA variants associated with other traits/diseases have been identified. For example, there is overwhelming evidence that suggests that the nature and intensity of an inflammatory response in adults and children are under genetic control. Because inflammation is often invoked as an etiologic factor in spontaneous preterm birth, the question of whether spontaneous preterm birth has a genetic predisposition in the case of pathologic inflammation has been of long-standing interest to investigators. Here, we review various genetic approaches used for the discovery of preterm birth genetic variants in the context of inflammation-associated spontaneous preterm birth. Candidate gene studies have sought genetic variants that regulate inflammation in the mother and fetus; however, the promising findings have often not been replicated. Genome-wide association studies, an approach to the identification of chromosomal loci responsible for complex traits, have also not yielded compelling evidence for DNA variants predisposing to preterm birth. A recent genome-wide association study that included a large number of White women (>40,000) revealed that maternal loci contribute to preterm birth. Although none of these loci harbored genes directly related to innate immunity, the results were replicated. Another approach to identify DNA variants predisposing to preterm birth is whole exome sequencing, which examines the DNA sequence of protein-coding regions of the genome. A recent whole exome sequencing study identified rare mutations in genes encoding for proteins involved in the negative regulation (dampening) of the

    Preterm birth occurs before 37 completed weeks, its causes are multifactorial and vary according to the gestational age, ethnicity and geographical context. Although several medical/social factors have been clearly identified, over 50% of cases are unknown or unclear; however, psychopathological components emerge as potentially important risk factors. To determine the relationship between the presence of stress during pregnancy and spontaneous preterm birth. Through a study of cases and controls in a level III hospital, with a sample of 360 patients during the period from March to November of 2013, where sociodemographic characteristics were collected. In addition, they were applied scales social adjustment, coping strategies and social support. Logistic regression models were developed; psychological, biological and social. Based on the significant variables in each of these generated a final one. The final model was found that stress during pregnancy increases the odds of spontaneous preterm birth 1.91 times (adjusted OR=2.91; 95%CI, 1.67-5.08; P<.05). Other significant variables were: history of preterm delivery, unplanned pregnancy, no emotional support, rural residence, inadequate prenatal care and non-stable partner. The findings support the hypothesis that stress during pregnancy is associated with spontaneous preterm delivery. Copyright © 2015 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

  7. Spontaneous abortion and unexpected death: a critical discussion of Marquis on abortion.

    Science.gov (United States)

    Coleman, Mary Clayton

    2013-02-01

    In his classic paper, 'Why abortion is immoral', Don Marquis argues that what makes killing an adult seriously immoral is that it deprives the victim of the valuable future he/she would have otherwise had. Moreover, Marquis contends, because abortion deprives a fetus of the very same thing, aborting a fetus is just as seriously wrong as killing an adult. Marquis' argument has received a great deal of critical attention in the two decades since its publication. Nonetheless, there is a potential challenge to it that seems to have gone unnoticed. A significant percentage of fetuses are lost to spontaneous abortion. Once we bring this fact to our attention, it becomes less clear whether Marquis can use his account of the wrongness of killing to show that abortion is the moral equivalent of murder. In this paper, I explore the relevance of the rate of spontaneous abortion to Marquis' classic anti-abortion argument. I introduce a case I call Unexpected Death in which someone is about to commit murder, but, just as the would-be murderer is about to strike, his would-be victim dies unexpectedly. I then ask: what does Marquis' account of killing imply about the moral status of what the would-be murderer was about to do? I consider four responses Marquis could give to this question, and I examine what implications these responses have for Marquis' strategy of using his account of the wrongness of killing an adult to show that abortion is in the same moral category.

    The aim of this study was the characterization of the implantation site through histological and immunohistochemical exams and the evaluation of the changes that appear in the pregnancies ended by spontaneous abortion compared to normal pregnancies ended by requested abortion. One hundred eight patients were divided in two groups: the study group that included 58 patients with spontaneous abortion and the control group that included 50 patients with requested abortion. There has been made uterine curettage in all the cases after a complete preoperative evaluation and the obtained product was sent for histopathological evaluation and immunohistochemical study using a VEGF antibody. Studying the histological sections, we noticed the vasculogenesis stages chronology and then according to the histological aspects of normal pregnancy we noticed the histological changes that occurred at the site of implantation in the cases with pathological pregnancies ended by miscarriage. Our results from this study seem to indicate a correlation between decidual vascular changes and the appearance of miscarriage. In pregnancies ended by miscarriage, we found delays in the trophoblast development according to the gestational age at which the event abortifacient happened. The study emphases the temporal differentiation of utero-placental angiogenesis comparing to villous vasculogenesis and angiogenesis in the first trimester miscarriage and normal pregnancy. At the control group, VEGF expression was positive in 88% of cases, while in the study group, pregnancies ended by spontaneous abortion, positive expression of VEGF was present in only 31% of cases. Our data suggest vascular disorders and are in concordance with other histological and ultrasound studies postulating the idea of a link between miscarriage and placental vascular bed pattern changes.

    Full Text Available Objective. To profile maternal plasma metabolome in spontaneous preterm birth. Method. In this retrospective case-control study, we have examined plasma of patient with preterm birth (between 22 and 36 weeks of pregnancy (n=57, with threatened preterm labor (between 23 and 36 weeks of pregnancy (n=49, and with term delivery (n=25. Plasma samples were analysed using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-Q-TOF-MS in positive and negative polarity modes. Results. We found 168 differentially expressed metabolites that were significantly distinct between study groups. We determined 51 metabolites using publicly available databases that could be subdivided into one of the five groups: amino acids, fatty acids, lipids, hormones, and bile acids. PLS-DA models, verified by SVM classification accuracy, differentiated preterm birth and term delivery groups. Conclusions. Maternal plasma metabolites are different between term and preterm parturitions. Part of them may be related with preterm labor, while others may be affected by gestational age or the beginning of labor. Metabolite profile can classify preterm or term delivery groups raising the potential of metabolome as a biomarker to identify high-risk pregnancies. Metabolomic studies are also a tool to detect individual compounds that may be further tested in targeted researches.

    Spontaneous heterotopic pregnancy is a rare clinical condition in which intrauterine and extrauterine pregnancies occur at the same time. It is rare, estimated to occur in 1 in 30,000 pregnancies. The case was a 38-year-old woman with spontaneously conceived heterotopic pregnancy. She was admitted to our center with hypovolemic shock. Focused assessment sonography for trauma examination in emergency department showed large amount of free fluid in peritoneal cavity. She was managed surgical laparotomy. Considering spontaneous pregnancies, physician should be aware of the possibility of heterotopic pregnancy in all reproductive age women, especially those with history of recent abortion. It can occur without any predisposing risk factors. Patients should be informed about possible side effects of nonprescription medicines, and also the health care centers must be safe peaceful environment for them without severe legal consequences.

    2004-03-01

    The objective of this study was to investigate the relationship between history of induced abortion and preterm delivery in various parts of Europe, and according to the main cause of preterm birth. We used data from a case-control survey, the EUROPOP study; 2938 preterm births and 4781 controls at term from ten European countries were included. Based on national statistics, we distinguished three groups of countries with high, intermediate and low rates of induced abortion. Previous induced abortions were significantly associated with preterm delivery and the risk of preterm birth increased with the number of abortions. Odds ratios did not differ significantly between the three groups of countries. The extent of association with previous induced abortion varied according to the cause of preterm delivery. Previous induced abortions significantly increased the risk of preterm delivery after idiopathic preterm labour, preterm premature rupture of membranes and ante-partum haemorrhage, but not preterm delivery after maternal hypertension. The strength of the association increased with decreasing gestational age at birth. Identifying subgroups of preterm births on the basis of the complications involved in delivery increases our understanding of the mechanisms by which previous induced abortion affects subsequent pregnancy outcomes.

    Prenatal stress and depression affects 10-25% of pregnant women and is associated with disruption of fetal neurodevelopment, higher rates of placental abnormalities, preeclampsia, spontaneous abortion, or preterm birth. Markers of genetic vulnerability are catechol-O-methyltransferase, monoamine oxidase-A, variation of serotonin transporters, low levels of dopamine-beta-hydroxylase, and brain derived neurotrophic factor Val66Met (BDNF), while hyperactivity of HPA (hypothalamic-pituitary-adrenal) axis and massive release of endogenous cortisol, regulated by metalloproteinase-1, -2, -3 and -9, and are involved both in depressive symptoms and neurodevelopmental abnormalities in fetus. In women with prenatal stress and depression which suffered spontaneous abortion were observed placental abnormalities as regular shape and necrotic villi, decidua with large areas of necrosis, acute inflammation and effusion areas correlated with increase in proinflammatory factors, immune deficit and infections, hyaline type fibrosis, intervilos and deciduous intense hemorrhage, associated with increase of vascular endothelial growth factor. Taking into account the important societal and economic costs becomes important for an interdisciplinary approach, in which pregnancy and its risks are a central point for women mental health.

    To assess the occurrence of spontaneous abortion, comparing two different data sources. To estimate the rate of spontaneous abortion over a 2-year period, and examine potential predictors of the risk for incident spontaneous abortion. We used interview data from a population-based prospective cohort study comprising 11,088 women and data from a linkage of the cohort with the Hospital Discharge Register to compare spontaneous abortions as reported in the interview with those identified in the register. Based on interview data, we estimated the rate of spontaneous abortion during the two-year follow-up. Finally, risk determinants for incident spontaneous abortion were analyzed by means of logistic regression. A total of 654 spontaneous abortions before enrolment in the study were reported by the women compared to 531 abortions found in the register. More than 80% of the spontaneous abortions identified from both sources were recorded in the same year. During follow-up a total of 20.9% of pregnancies intended to be carried to term ended as a spontaneous abortion. In the risk factor analysis, we found that previous spontaneous abortion, being single, never having used oral contraceptives, and use of intrauterine device were associated with increased risk of subsequent spontaneous abortion. In addition, it was indicated that a short interpregnancy interval following a spontaneous abortion may confer an increased risk of abortion in the subsequent pregnancy. We found a high rate of spontaneous abortion in the present study and an acceptable agreement between information obtained by interview and register information. More than 25% of the spontaneous abortions were only reported by the women, and this could not be explained by erroneously reported induced abortions, and may be early, nonhospitalized abortions. We confirm that number of previous spontaneous abortions is a strong determinant, and our data may also indicate a role of previous contraceptive habits. A role of

    Full Text Available We describe a rare case of fatal disseminated tuberculous peritonitis in a young woman with rapid progressive clinical course following spontaneous abortion of 20-week gestation. Clinical and laboratory findings were initially unremarkable. She underwent diagnostic laparoscopy which revealed numerous tiny implants on the peritoneum and viscera. Histopathology showed chronic caseating granulomas, and the tissue culture grew Mycobacterium tuberculosis. At fifth day of the antituberculous treatment multiorgan failure occurred in terms of pulmonary, hepatic, and renal insufficiency. She developed refractory metabolic acidosis with coagulopathy and pancytopenia, and she died of acute respiratory distress syndrome and septic shock on her twelfth day of hospitalization.

    Background To determine whether patients with placenta previa who delivered preterm have an increased risk for recurrent spontaneous preterm birth. Methods This retrospective population based cohort study included patients who delivered after a primary cesarean section (n = 9983). The rate of placenta previa, its recurrence, and the risk for recurrent preterm birth were determined. Results Patients who had a placenta previa at the primary CS pregnancy had an increased risk for its recurrence [crude OR of 2.65 (95% CI 1.3-5.5)]. The rate of preterm birth in patients with placenta previa in the primary CS pregnancy was 55.9%; and these patients had a higher rate of recurrent preterm delivery than the rest of the study population (p placenta previa in the primary CS pregnancy, those who delivered preterm had a higher rate of recurrent spontaneous preterm birth regardless of the location of their placenta in the subsequent delivery [OR 3.09 (95% CI 2.1-4.6)]. In comparison to all patients with who had a primary cesarean section, patients who had placenta previa and delivered preterm had an independent increased risk for recurrent preterm birth [OR of 3.6 (95% CI 1.5-8.5)]. Conclusions Women with placenta previa, who deliver preterm, especially before 34 weeks of gestation, are at increased risk for recurrent spontaneous preterm birth regardless to the site of placental implantation in the subsequent pregnancy. Thus, strict follow up by high risk pregnancies specialist is recommended. PMID:22876799

    To assess a possible association between polymorphism of the progesterone receptor gene (PROGINS) and recurrent spontaneous abortion (RSA). In this case-control study, 85 women with at least three previous spontaneous abortions without an identifiable cause (RSA Group) and 157 women with at least two previous term pregnancies without pathologies and no previous miscarriage (Control Group) were selected. An amount of 10 mL of peripheral blood was collected by venipuncture and genomic DNA was extracted by the DTAB/CTAB method, followed by the polymerase chain reaction (PCR) under specific conditions for this polymorphism and by amplification by 2% agarose gel electrophoresis. The bands were visualized with an ultraviolet light transilluminator and the gels were photographed. Differences in the PROGINS genotype and allele frequencies between groups were analyzed by the χ² test, with the level of significance set at p<0.05. The Odds Ratio (OR) was also used, with 95% confidence intervals 95%CI. PROGINS genotypic frequencies were 72.3% T1T1 and 27.7% T1T2 for the RSA group and 76.4% T1T1, 22.3% T1T2 and 1.3% T2T2 for the control group. There were no differences between groups when the genotype and allele frequencies were analyzed: respectively p=0.48 (OR: 0.8) and p=0.65 (OR: 0.9). Our results suggest that PROGINS polymorphism is not associated with RSA.

    Full Text Available Reproductive health is exquisitely sensitive to characteristics of an individual’s environment including physical, biological, behavioral, cultural and socioeconomic factors. This study was launched to elucidate the effect of the exposure to chemical pollutants as aromatic amines viz. (benzidine, mono-acetyl benzidine, diacetyl benzidine, α,β-naphthylamine as well as the biological pollutants e.g., human cytomegalovirus (HCMV as risk factors for recurrent spontaneous abortion (RSA through determination of MDA as a marker of oxidative stress and determination of some antioxidant markers. The results of the current study revealed that the aborter mothers were being exposed to environmental pollutants as aromatic amines which were manifested by the presence of benzidine, mono-acetyl-benzidine, di-acetyl-benzidine, α,β-naphthylamine in most of their urine samples, where the level of aromatic amines were more 13.6, 10, 15, and 4-folds than the control group, respectively. Also, the data suggest that in early pregnancy failure there is an increase in markers of oxidative stress and a probable decrease in maternal antioxidant defenses (22 nmol/ml and 17 mg/l, 550 U/l, respectively. Generation of ROS in large quantities, in the first trimester placenta which has limited antioxidant defenses may cause DNA damage, oxidation of protein and lipid resulting in extensive cell death. Also, it was demonstrated that high elevation of HCMV inhibits cytotrophoblasts proliferation, migration invasion and matrix metalloproteins (MMP expression. Obviously, placental toxicological responses are partly due to pharmaco/toxico dynamic responses to the chemicals. Conclusively, the aforementioned findings emphasis that, the exposures to environmental chemical and/or biological risk factors are implicated in the pathogenesis of recurrent spontaneous abortion.

    To investigate the correlation of genomic DNA methylation level with unexplained early spontaneous abortion and analyze the role of DNMT1, DNMT3A and DNMT3B. Forty-five villus samples from spontaneous abortion cases (with 33 maternal peripheral blood samples) and 44 villus samples from induced abortion (with 34 maternal peripheral blood samples) were examined with high-pressure liquid chromatography (HPLC) to measure the overall methylation level of the genomic DNA. The expressions of DNMT mRNAs were detected using fluorescence quantitative-PCR in the villus samples from 33 induced abortion cases and 30 spontaneous abortion cases. Genomic DNA methylation level was significantly lower in the villus in spontaneous abortion group than in induced abortion group (P0.05). The mean mRNA expression levels of DNMT1 and DNMT3A in the villus were significantly lower in spontaneous abortion group than in induced abortion group (P0.05). Insufficient genomic DNA methylation in the villus does exist in human early spontaneous abortion, and this insufficiency is probably associated with down-regulated expressions of DNMT1 and DNMT3A.

    To investigate the relationship between different indicators of socioeconomic position and the risk of spontaneous abortion. Cohort study. 1996-2002, Denmark. All first time participants, a total of 89 829 pregnant women, enrolled in the Danish National Birth Cohort were included in the present study. Overall, 4062 pregnancies ended in spontaneous abortion. Information on education, income and labour market attachment in the year before pregnancy was drawn from national registers. Spontaneous abortion, that is, fetal death within the first 22 weeks of pregnancy, was the outcome of interest. The authors estimated HRs of spontaneous abortion using Cox regression analysis with gestational age as the underlying time scale. Women with abortion when compared with women with >12 years of education (HR 1.19 (95% CI 1.05 to 1.34)). The HR estimates for the four lowest income quintiles were all increased (HRs between 1.09 and 1.15) as compared with the upper quintile but did not differ considerably from each other. In general, no statistically significant association was found between labour market attachment and the risk of spontaneous abortion; however, the group of women on disability pension had an increased HR of spontaneous abortion when compared with women who were employed (HR 1.32 (95% CI 0.82 to 2.13)). Educational level and income were inversely associated with the risk of spontaneous abortion. As these factors most likely are non-causally related to spontaneous abortion, the findings indicate that factors related to social position, probably of the environmental and behavioural type, may affect spontaneous abortion risk. The study highlights the need for studies addressing such exposures in order to prevent spontaneous abortions.

    The literature shows a variable and inconsistent relationship between socioeconomic position and preterm birth. We examined risk factors for spontaneous and iatrogenic preterm birth, with a focus on socioeconomic position and clinical risk factors, in order to explain the observed inconsistency. We carried out a retrospective population-based cohort study of all singleton deliveries in Nova Scotia from 1988 to 2003. Data were obtained from the Nova Scotia Atlee Perinatal Database and the federal income tax T1 Family Files. Separate logistic models were used to quantify the association between socioeconomic position, clinical risk factors and spontaneous preterm birth and iatrogenic preterm birth. The study population included 132,714 singleton deliveries and the rate of preterm birth was 5.5%. Preterm birth rates were significantly higher among the women in the lowest (versus the highest) family income group for spontaneous (rate ratio 1.14, 95% confidence interval (CI) 1.03, 1.25) but not iatrogenic preterm birth (rate ratio 0.95, 95% CI 0.75, 1.19). Adjustment for maternal characteristics attenuated the family income-spontaneous preterm birth relationship but strengthened the relationship with iatrogenic preterm birth. Clinical risk factors such as hypertension were differentially associated with spontaneous (rate ratio 3.92, 95% CI 3.47, 4.44) and iatrogenic preterm (rate ratio 14.1, 95% CI 11.4, 17.4) but factors such as diabetes mellitus were not (rate ratio 4.38, 95% CI 3.21, 5.99 for spontaneous and 4.02, 95% CI 2.07, 7.80 for iatrogenic preterm birth). Socioeconomic position and clinical risk factors have different effects on spontaneous and iatrogenic preterm. Recent temporal increases in iatrogenic preterm birth appear to be responsible for the inconsistent relationship between socioeconomic position and preterm birth.

    Preterm birth is a leading cause of perinatal morbidity and mortality worldwide, resulting in a pressing need to identify risk factors leading to effective interventions. Limited evidence suggests potential relationships between maternal sleep or vital exhaustion and preterm birth, yet the literature is generally inconclusive. We examined the relationship between maternal sleep duration and vital exhaustion in the first six months of pregnancy and spontaneous (non-medically indicated) preterm birth among 479 Peruvian women who delivered a preterm singleton infant (exhaustion were ascertained through in-person interviews. Spontaneous preterm birth cases were further categorized as those following either spontaneous preterm labor or preterm premature rupture of membranes. In addition, cases were categorized as very (exhaustion was also associated with increased odds of preterm birth (aOR = 2.41; 95% CI 1.79-3.23) compared to no exhaustion (Ptrend exhaustion on the odds of spontaneous preterm birth. The results of this case-control study suggest maternal sleep duration, particularly short sleep duration, and vital exhaustion may be risk factors for spontaneous preterm birth. These findings call for increased clinical attention to maternal sleep and the study of potential intervention strategies to improve sleep in early pregnancy with the aim of decreasing risk of preterm birth.

    To evaluate prospectively the relationship between prepregnancy folate intake and risk of spontaneous abortion and stillbirth. Women in the Nurses' Health Study II who self-reported a pregnancy between 1992 and 2009 were included in this analysis. Dietary folate and supplement use was assessed every 4 years, starting in 1991, by a food frequency questionnaire. Pregnancies were self-reported with case pregnancies lost spontaneously (spontaneous abortion less than 20 weeks of gestation and stillbirth 20+ weeks of gestation) and comparison pregnancies ending in ectopic pregnancy, induced abortion, or live birth. Among the 11,072 women, 15,950 pregnancies were reported of which 2,756 (17.3%) ended in spontaneous abortion and 120 (0.8%) ended in stillbirth. Compared with women in the lowest quintile of prepregnancy folate intake (less than 285 micrograms/d), those in the highest quintile (greater than 851 micrograms/d) had a relative risk of spontaneous abortion of 0.91 (95% confidence interval [CI] 0.82-1.02) after multivariable adjustment (P trend=.04). This association was primarily attributable to intake of folate from supplements. Compared with women without supplemental folate intake (0 micrograms/d), those in the highest category (greater than 730 micrograms/d) had a relative risk of spontaneous abortion of 0.80 (95% CI 0.71-0.90) after multivariable adjustment (P trend spontaneous abortion was consistent across gestational period of loss. A similar inverse trend was observed with the risk of stillbirth, which fell short of conventional significance (P trend=.06). Higher intake of folate from supplements was associated with reduced risk of spontaneous abortion. Women at risk of pregnancy should use supplemental folate for neural tube defect prevention and because it may decrease the risk of spontaneous abortion. : II.

    Induced abortion has been inconsistently associated with breast cancer risk in case-control studies. Retrospective cohort studies using registry information in Scandinavia have not suggested an increase in the incidence of breast cancer, although data on individual reproductive factors were not accounted for. We examined the association between induced and spontaneous abortion and the incidence of breast cancer in a prospective cohort of young women, the Nurses' Health Study II. The study included 105 716 women 29 to 46 years old at the start of follow-up in 1993. Information on induced or spontaneous abortions was collected in 1993 and updated biennially. During 973 437 person-years of follow-up between 1993 and 2003, 1458 newly diagnosed cases of invasive breast cancer were ascertained. A total of 16 118 participants (15%) reported a history of induced abortion, and 21 753 (21%) reported a history of spontaneous abortions. The hazard ratio for breast cancer among women who had 1 or more induced abortions was 1.01 (95% confidence interval, 0.88-1.17) after adjustment for established breast cancer risk factors; among women with 1 or more spontaneous abortions, the covariate-adjusted hazard ratio was 0.89 (95% confidence interval, 0.78-1.01). The relation between induced abortion and the incidence of breast cancer did not differ materially by number of abortions (P for trend = .98), age at abortion (P for trend = .68), parity (P for interaction = .54), or timing of abortion with respect to a full-term pregnancy (P for interaction = .10). Among this predominantly premenopausal population, neither induced nor spontaneous abortion was associated with the incidence of breast cancer.

    Parents of 751 children affected by cancer/leukemia, congenital heart disease, strawberry nevus or mental retardation have been investigated with respect to their reproductive history and their exposure to risk factors for spontaneous abortion. Differences between the four groups were established for the number of children in the sibship, the proportion of multigravidae and the spontaneous abortion rate among these women. The greatest differences were observed in the two groups of malformed children compared with the other two groups, being as marked in those with a severe malformation (heart defect) as in those with a benign one (strawberry nevus). Taking known risk factors for spontaneous abortion into account did not explain the observed differences. An etiological hypothesis is put forward which takes account of the high proportion of quantitative abnormalities of the karyotype associated with congenital heart disease and spontaneous abortion.

    A repeated or habitual miscarriage (PSP) is defined as three or more consecutive losses of pregnancy. In the first three months of pregnancy, habitual miscarriages occur in about 1% of pregnant women, out of which 50% are of an unknown etiology. It is believed that among them, the greatest number is the consequence of an inadequate alloimmune response of a women to the pregnancy. The endocrine and immune systems are in a close interaction during the implantation and maintaining of pregnancy. This communication is the most obvious on endometrium of pregnancy decidua. The aim of the study was to identify the number and the subpopulation distribution of the decidual NK cells in the decidua by using an immunohistochemical method. The research included a group of 30 women who had had two spontaneous miscarriages consecutively in the first three months of their pregnancy, while the curettage after the third spontaneous abortion was histopathologically and immunohistochemically analyzed. The control group consisted of 20 women without a problematic reproductive anamnesis, who had had their pregnancy terminated for social reasons. The criteria for the eliminating from the research were the diagnosed uterus anomalies, positive screening on thrombophilia, as well as women suffering from diabetes melitus and the ones with the thyroid gland function disorder. The number and the phenotype structure of the uterus NK cells were significantly different between the decidua of a normal pregnancy and that in PSP. In the decidua in PSP, there were much more NK cells with the phenotype of the peripheral circulation CD57 and CD56dim, while in the decidua of the control group the dominant cells were the typical uNK cell subpopulation CD56bright. The above mentioned results show that the disregulation of the immunocompetent cells of the decidua, by creating an inadequate cytokine milieu, is one of the mechanism of rejecting the semiallogeneic blastocyst.

    IL-18 is a multifunctional cytokine capable of inducing either Th1 or Th2 polarization depending on the immunologic milieu. IL-18 is detected at the materno-fetal interface very soon in early pregnancy. Two polymorphisms in the promoter region of the IL-18 gene at positions of -607 and -137 appear to have functional impacts. This study attempts to evaluate the frequency of these two polymorphisms in the IL-18 gene promoter in patients with recurrent spontaneous abortion (RSA) and normal pregnant women. One hundred and two RSA patients and 103 healthy pregnant women were enrolled in this study. Single nucleotide polymorphisms of the IL-18 gene at positions -607 (C/A) and -137 (G/C) were analyzed by the sequence-specific PCR method. There was no significant association between the allele, genotype, and haplotype frequencies of the two single nucleotide polymorphisms (SNPs) in the IL-18 gene promoter and RSA. The results of this study showed that IL-18 gene promoter polymorphisms at positions -607 and -137 did not confer susceptibility to RSA in southern Iranian patients.

    The risk of relapse of depression or the diagnosis of some other psychiatric disorders during pregnancy necessitates the use of antidepressants despite possible adverse effects. Whether such use increases the risk of spontaneous abortion is still being debated. We evaluated the risk of spontaneous abortion in relation to the use of antidepressants during pregnancy. Using a nested case-control study design, we obtained data from the Quebec Pregnancy Registry for 5124 women who had a clinically detected spontaneous abortion. For each case, we randomly selected 10 controls from the remaining women in the registry who were matched by the case's index date (date of spontaneous abortion) and gestational age at the time of spontaneous abortion. Use of antidepressants was defined by filled prescriptions and was compared with nonuse. We also studied the classes, types and doses of antidepressants. A total of 284 (5.5%) of the women who had a spontaneous abortion had at least one prescription for an antidepressant filled during the pregnancy, as compared with 1401 (2.7%) of the matched controls (odds ratio [OR] 2.09, 95% confidence interval [CI] 1.83-2.38). After adjustment for potential confounders, we found that the use of antidepressants during pregnancy was associated with an increased risk of spontaneous abortion (OR 1.68, 95%CI 1.38-2.06). Stratified analyses showed that use of selective serotonin reuptake inhibitors alone (OR 1.61, 95% CI 1.28-2.04), serotonin-norepinephrine reuptake inhibitors alone (OR 2.11, 95% CI 1.34-3.30) and combined use of antidepressants from different classes (OR 3.51, 95% CI 2.20-5.61) were associated with an increased risk of spontaneous abortion. When we looked at antidepressant use by type versus no use, paroxetine use alone (OR 1.75, 95% CI 1.31-2.34) and venlafaxine use alone (OR 2.11, 95% CI 1.34-3.30) were associated with an increased risk of spontaneous abortion.

Methods This retrospective population based cohort study included patients who delivered after a primary cesarean section (n = 9983. The rate of placenta previa, its recurrence, and the risk for recurrent preterm birth were determined. Results Patients who had a placenta previa at the primary CS pregnancy had an increased risk for its recurrence [crude OR of 2.65 (95% CI 1.3-5.5]. The rate of preterm birth in patients with placenta previa in the primary CS pregnancy was 55.9%; and these patients had a higher rate of recurrent preterm delivery than the rest of the study population (p Conclusions Women with placenta previa, who deliver preterm, especially before 34 weeks of gestation, are at increased risk for recurrent spontaneous preterm birth regardless to the site of placental implantation in the subsequent pregnancy. Thus, strict follow up by high risk pregnancies specialist is recommended.

    Full Text Available In the present study, using immunohistochemistry, we studied the expression of CD30 and CD30-L in 35 deciduas obtained from women following elective abortion during normal physiological gestation and in 60 deciduas obtained from women after spontaneous abortion with or without signs of inflammation. The main difference was noticed in the first trimester of gestation in which was found a decrease in CD30/CD30-L-positive decidual glandular and stromal cells in a greater number of cases of spontaneous abortions with respect to cases of physiological pregnancies (70% vs 50%, p<0.05. In addition, deciduas from spontaneous abortions with inflammation and without inflammation reacted similarly. The reduced expression of CD30 and CD30-L and their cellular pattern detected in the deciduas from spontaneous abortions suggest that the CD30/CD30-L system is crucial for preventing abortions in the first trimester. And furthermore, the distinctive expression of CD30/CD30- L in deciduas from physiological pregnancies may indicate that the CD30/CD30-L system exerts its main role in the first trimester.

    Moderate fish intake in early pregnancy is associated with decreased risk of preterm birth (PTB). Obesity during pregnancy is characterized by inflammation and insufficiency of essential fatty acids. The objective of this study was to measure the association between fish intake during pregnancy and risk of recurrent spontaneous (s) PTB among lean, overweight, and obese women. This is secondary analysis of a randomized controlled trial of omega-3 fatty acid supplementation for recurrent PTB prevention, 2005-2006. The primary exposure was fish intake at time of enrollment (16-22.9-week gestation). The primary outcomes were sPTB <37 weeks and sPTB <35 weeks. Maternal prepregnancy body mass index was treated as an effect modifier. Eight hundred and fifty-two women were included, 47% were lean, 25% overweight, and 28% obese. In this cohort, among lean, but not overweight or obese women, ≥1 serving of fish per week was associated with decreased frequency of sPTB <37 weeks compared with <1 serving of fish per week (45.1% versus 27.5%, p = .001) and spontaneous PTB <35 (21.4% versus 11.6%, p = .01). In adjusted models, as fish intake increased, the predicted probability of sPTB decreased in lean women but increased in overweight and obese women (p for interaction < .10). Fish intake was associated with lower probability of sPTB in lean women and higher probability in obese women. These findings warrant further investigation to understand the dietary or metabolic factors associated with obesity that may modulate benefit of fish intake during pregnancy.

    Numerous studies have documented the negative effects of maternal alcohol consumption during pregnancy on risk of pregnancy loss, yet whether prepregnancy alcohol intake affects the risk of spontaneous abortion is still unclear. This study aimed to assess prepregnancy alcohol intake and risk of spontaneous abortion and stillbirth. Our prospective cohort study included 27,580 pregnancies reported by 17,929 women in the Nurses' Health Study II between 1990 and 2009. Alcohol intake was assessed in 1989 and 1991 and every 4 y thereafter with the use of a validated questionnaire. Women were classified into 5 categories of consumption: 0, 0.1-1.9, 2-4.9, 5-9.9, and ≥10 g/d (1 serving = ∼12 g). Pregnancies were self-reported, with case pregnancies lost spontaneously (spontaneous abortion after gestation of abortion). Multivariable log-binomial regression models with generalized estimating equations were used to estimate RRs and 95% CIs. Incident spontaneous abortion and stillbirth were reported in 4326 (15.7%) and 205 (0.7%) pregnancies, respectively. Prepregnancy alcohol intake was not associated with spontaneous abortion. Compared with women who did not consume alcohol, the multivariable RRs (95% CIs) for increasing categories of alcohol intake among women who did consume alcohol were 1.04 (0.97, 1.12) for 0.1-1.9 g/d, 1.02 (0.94, 1.11) for 2-4.9 g/d, 1.01 (0.92, 1.10) for 5-9.9 g/d, and 0.98 (0.88, 1.09) for ≥10 g/d (P-trend = 0.45). Women who consumed ≥2 servings beer/wk before pregnancy had a 9% (95% CI: 1%, 17%) lower risk of spontaneous abortion than did women who consumed spontaneous abortion. Total alcohol and specific alcohol beverage intake before pregnancy were not associated with stillbirth. Prepregnancy alcohol intake was not related to risk of incident spontaneous abortion or stillbirth in women with no history of pregnancy loss. Our results provide reassuring evidence that low to moderate alcohol intake (≤12 g/d) before pregnancy initiation does

    Low plasma folate concentrations in pregnancy are associated with preterm birth. Here we show an association between preconceptional folate supplementation and the risk of spontaneous preterm birth. In a cohort of 34,480 low-risk singleton pregnancies enrolled in a study of aneuploidy risk, preconceptional folate supplementation was prospectively recorded in the first trimester of pregnancy. Duration of pregnancy was estimated based on first trimester ultrasound examination. Natural length of pregnancy was defined as gestational age at delivery in pregnancies with no medical or obstetrical complications that may have constituted an indication for delivery. Spontaneous preterm birth was defined as duration of pregnancy between 20 and 37 wk without those complications. The association between preconceptional folate supplementation and the risk of spontaneous preterm birth was evaluated using survival analysis. Comparing to no supplementation, preconceptional folate supplementation for 1 y or longer was associated with a 70% decrease in the risk of spontaneous preterm delivery between 20 and 28 wk (41 [0.27%] versus 4 [0.04%] spontaneous preterm births, respectively; HR 0.22, 95% confidence interval [CI] 0.08-0.61, p = 0.004) and a 50% decrease in the risk of spontaneous preterm delivery between 28 and 32 wk (58 [0.38%] versus 12 [0.18%] preterm birth, respectively; HR 0.45, 95% CI 0.24-0.83, p = 0.010). Adjustment for maternal characteristics age, race, body mass index, education, marital status, smoking, parity, and history of prior preterm birth did not have a material effect on the association between folate supplementation for 1 y or longer and spontaneous preterm birth between 20 and 28, and 28 to 32 wk (adjusted HR 0.31, 95% CI 0.11-0.90, p = 0.031 and 0.53, 0.28-0.99, p = 0.046, respectively).

Prospective study of 87 women referred for cervical length assessment with a standardized TVUS combined to vaginal secretions sampling. Samples were analyzed for presence of 10 cytokines. Main outcome was sPTB (cervix (cervix and IL-8 in vaginal secretions were independently associated with sPTB (OR 3.58 (95%CI 1.02; 12.61) and 14.55 (95%CI 1.64; 128.83), respectively) as their combination (OR 4.33 (95%CI 1.25; 14.95)). By categorizing cervical length by presence of IL-8, sPTB occurred in 55.6% of women with a short inflamed cervix. COLIBRI study used a novel, single-step method of vaginal secretions sampling during TVUS and demonstrated that combination of short cervix and IL-8 in vaginal secretions is a promising sPTB predictive test.

    To investigate the expression of human spindle mitosis arrest deficiency gene (hsMAD2) in spontaneous abortion embryos and the relationship between low expression of hsMAD2 and numerical chromosomal aberration. METHODS Spontaneous abortion embryo tissues were collected, including 23 cases of once spontaneous abortion tissue and 10 cases of twice or more spontaneous abortion tissue and induced abortion embryos (35 cases) from the Department of Gynaecology and Obstetrics of the Affiliated Hospitals of Chongqing University of Medical Science during the period of March 2006 to March 2007. FQ-PCR and western blot were used to evaluate the endogenous expression level of hsMAD2 mRNA and hsMAD2 protein; primary culturing of cells from the induced abortion embryos was conducted and 5 embryonic cells were selected by chromosomes karyotype analysis. Recombinant shRNA plasmids targeting hsMAD2 gene were constructed to inhibit the expression of endogenous hsMAD2 genes in embryonic cells which have normal karyotypes; the groups were defined as the first experimental group (transfected with pshRNA-hsMAD2-1) , the second experimental group (transfected with pshRNA-hsMAD2-2), the third experimental group (transfected with pshRNA-hsMAD2-3), the first control group (transfected with nothing), the second control group (transfected with pTZU6 + 1) and the independent group (transfected with pshRNA-N1). Interference efficiency was demonstrated by FQ-PCR and western blot; cell proliferation was measured by methyl thiazolyl tetrazolium (MTT) assay; cell-cycle was assessed by flow cytometry (FCM); the chromosome numbers were calculated to analyze the variation of chromosomes. (1) The mRNA levels of hsMAD2 in the once spontaneous abortion tissue, twice or more spontaneous abortion tissue and induced abortion tissue were 0.00879 +/- 0.00035, 0.00901 +/- 0.00033 and 0.00941 +/- 0.00026 respectively, and there was no significant difference (P > 0.05) compared with each other; however, the

    Spontaneous cries of infants exhibit rich melodic features (i.e., time variation of fundamental frequency [ F 0 ]) even during the neonatal period, and the development of these characteristics might provide an essential base for later expressive prosody in language. However, little is known about the melodic features of spontaneous cries in preterm infants, who have a higher risk of later language-related problems. Thus, the present study investigated how preterm birth influenced melodic features of spontaneous crying at term-equivalent age as well as how these melodic features related to language outcomes at 18 months of corrected age in preterm and term infants. At term, moderate-to-late preterm (MLP) infants showed spontaneous cries with significantly higher F 0 variation and melody complexity than term infants, while there were no significant differences between very preterm (VP) and term infants. Furthermore, larger F 0 variation within cry series at term was significantly related to better language and cognitive outcomes, particularly expressive language skills, at 18 months. On the other hand, no other melodic features at term predicted any developmental outcomes at 18 months. The present results suggest that the additional postnatal vocal experience of MLP preterm infants increased F 0 variation and the complexity of spontaneous cries at term. Additionally, the increases in F 0 variation may partly reflect the development of voluntary vocal control, which, in turn, contributes to expressive language in infancy.

    Full Text Available Human parvovirus B19 is a very common viral infection especially in school-aged children. The infection during pregnancy can affect the fetus due to lack of mother's immunity. Although, there is still no evidence of fetal teratogenic effects with parvovirus B19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. This study was aimed to assess the prevalence of parvovirus B19-specific antibody (IgM in pregnant women who had a spontaneous abortion. This cross-sectional study was carried out in all pregnant women who referred due to a spontaneous abortion. All demographic information such as age, occupation, and gestational age, last history of abortion, gravity, and presence of children below the age of six was recorded and a blood sample was provided for all the women. Then, the blood samples were tested to assay parvovirus B19-specific antibody (IgM by EuroImmune ELISA kit. Among 94 pregnant women with the mean age of 28.4 years who had a spontaneous abortion, parvovirus B19 specific antibody (IgM was detected in 17 participants (18.1%. Meanwhile, 14 women (14.9% were suspected for presence of the antibody in their blood sample. There was no significant difference between the presence of antibody and age of pregnant women, occupation, gestational age, number of previous abortion, presence of children below the age of six and number of pregnancy. These findings revealed that a high percentage of pregnant women are probably non-immune against parvovirus B19, and also there might be a number of spontaneous abortions in which parvovirus infection caused fetal death.  However, more studies are needed to prove the absolute role of parvovirus B19 in these abortions.

    Human parvovirus B19 is a very common viral infection especially in school-aged children. The infection during pregnancy can affect the fetus due to lack of mother's immunity. Although, there is still no evidence of fetal teratogenic effects with parvovirus B19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. This study was aimed to assess the prevalence of parvovirus B19-specific antibody (IgM) in pregnant women who had a spontaneous abortion. This cross-sectional study was carried out in all pregnant women who referred due to a spontaneous abortion. All demographic information such as age, occupation, and gestational age, last history of abortion, gravity, and presence of children below the age of six was recorded and a blood sample was provided for all the women.

    We investigated whether spontaneous antigravity limbs movements in very low birth weight preterm infants were insufficient compared to those in term infants. The relationship between the quality of general movements (GMs) and antigravity limbs movements was also examined. Preterm infants with very low birth weight without central nervous system disorders nor severe respiration disorders, and healthy term infants were recruited. The infants were set in a supine position. The distance between both hands and between both feet, and the height of both hands and feet from the floor were recorded at 1-3 corrected months for preterm infants, and at 1-3 months for term infants by a 3D motion capture system. The measurements were adjusted for body proportions. GMs in preterm and term infants were assessed similarly. Thirteen preterm and 15 term infants completed the study. In preterm infants, the distance between both hands and between both feet were longer, and the height of both hands and feet were lower than those in term infants in all measurements. In term infants, the height of both hands and feet increased as they developed, but no change was observed in preterm infants. In preterm infants with abnormal GMs, the distance between both hands was longer, and the height of both hands and feet was lower than that in those with normal GMs. There were no such differences between preterm infants with normal GMs and term infants with normal GMs. Antigravity limbs movements in preterm infants within the first 3 month of corrected age were insufficient compared with those in term infants. Furthermore, no improvement with development was observed in preterm infants. In addition, preterm infants with abnormal GMs showed worse antigravity limbs movements than preterm and term infants with normal GMs. The preterm infants with normal GMs could behave similar to the full term infants.

    Full Text Available Introduction & Objective: Nowadays, some studies indicate the adverse effects of exposure to chemicals, especially organic solvents on the reproductive system of females. This study aimed to assess the relationship between spontaneous abortion with occupational exposure to organic solvents in pharmaceutical industry. Materials & Methods: This is a cross-sectional and descriptive-analytical study which was carried out in 2010 in one of the pharmaceutical factories located in the suburbs of Tehran. During the study, married women who were working in the factory laboratory units and were exposed to mixed organic solvents were compared with married women who were working in the packing units of the factory without occupational exposure to organic solvents. Frequency of spontaneous abortion and duration of pregnancy were assessed in both two groups. Collected data were analyzed with the SPSS software using t-test, logistic regression, and chi-square test. Results: In the present study, the frequency of spontaneous abortion in employees with exposure to organic solvents mixture was 10.7%. This study showed that even after adjustment for confounding factors, there was a significant correlation between spontaneous abortion and occupational exposure to organic solvents mixture and this correlation increased with increasing levels of exposure to organic solvents. Moreover, a significant correlation was observed between occupational exposure to mixed organic solvents and waiting time to become pregnant (TTP. Furthermore, this study showed that even after adjustment for confounding variables, shift workers were significantly more affected by spontaneous abortion compared to daytime workers (P < 0.001. Conclusion: According to the results of this study, since there is probability of spontaneous abortion resulting from occupational exposure to various chemicals including organic solvents, review of the status of occupational exposure of workers can be helpful

    Full Text Available The heterogeneity of spontaneous preterm birth (SPTB requires an interdisciplinary approach to determine potential predictive risk factors of early delivery. The aim of this study was to investigate maternal whole blood gene expression profiles associated with spontaneous preterm birth (SPTB, <37 weeks in asymptomatic pregnant women. The study population was a matched subgroup of women (51 SPTBs, 114 term delivery controls who participated in the All Our Babies community based cohort in Calgary (n = 1878. Maternal blood at 17-23 (sampling time point 1, T1 and 27-33 weeks of gestation (T2 were collected. Total RNA was extracted and microarray was performed on 326 samples (165 women. Univariate analyses determined significant clinical factors and differential gene expression associated with SPTB. Thirteen genes were validated using qRT-PCR. Three multivariate logistic models were constructed to identify gene expression at T1 (Model A, T2 (Model B, and gene expression fold change from T1 to T2 (Model C associated with SPTB. All models were adjusted for clinical factors. Model C can predict SPTB with 65% sensitivity and 88% specificity in asymptomatic women after adjusting for history of abortion and anaemia (occurring before T2. Clinical data enhanced the sensitivity of the Models to predict SPTB. In conclusion, clinical factors and whole blood gene expression are associated with SPTB in asymptomatic women. An effective screening tool for SPTB during pregnancy would enable targeted preventive approaches and personalised antenatal care.

    This study estimated the effect of maternal sociodemographic, obstetric and lifestyle factors on the risk of spontaneous preterm birth in a Russian town. All women with singleton pregnancies registered at prenatal care centres in Severodvinsk in 1999 comprised the cohort for this study (n=1559). Analysis was based on spontaneous live singleton births at the maternity home (n=1103). Multivariable logistic regression was applied to quantify the effect of the studied factors on the risk of preterm birth. Differences in gestation duration were studied using multiple linear regression. In total, 5.6% of all spontaneous births were preterm. Increased risks of preterm delivery were found in women with lower levels of education and in students. Placental complications, stress and a history of fetal death in previous pregnancies were also associated with elevated risks for preterm delivery. Smoking, hypertension and multigravidity were associated with reduced length of pregnancy in metric form. In addition to medical risk factors, social factors are important determinants of preterm birth in transitional Russia. Large disparities in preterm birth rates may reflect the level of inequalities in transitional Russia. Social variations in pregnancy outcomes should be monitored.

From January to October 2012, the 26 patients with more than twice of spontaneous abortion in Huzhou Maternal and Child Health Care Hospital were enrolled in this study(RSA group). Meanwhile 20 cases with induced abortion were taken as control group. All aborted tissues were analyzed with conventional cytogenetic karyotyping and SNP-array, respectively. Chorionic villus chromosomal examination was successfully done in 19 cases (73%, 19/26) , which 10 cases were found with chromosomal anomaly, the overall detection rate is 10/19. However, SNP-array analysis was successfully performed in all 26 cases. The overall rate of detection was 100%, and abnormalities were found in 15 cases, which reached the detection rate was 58% (15/26). Chorionic villus chromosomal examination was successfully done in 16 cases (16/20) in control group, and none of the resluts was chomosomal anomaly; SNP-array analysis was successfully performed in all 20 cases (20/20), and none was found abnormalities. SNP-array gene chip technique showed highly accurate feature, which could be used in cytogenetic diagnosis of recurrent spontaneous abortion.

    To determine the impact of a history of spontaneous abortion on pre-eclampsia during a subsequent pregnancy. A cross-sectional study enrolled pregnant women admitted to obstetrics and gynecology wards at 103 hospitals in Tehran, Iran for delivery between July 6 and July 21, 2015. Consenting participants were interviewed by midwives; data were collected using a five-part questionnaire and patients' medical records were retrieved. Patient data were analyzed by multiple logistic regression to identify variables associated with increased odds of pre-eclampsia. In total, 5170 patients were interviewed and 252 had experienced pre-eclampsia. The number of previous spontaneous abortions was found to be associated with pre-eclampsia, and a higher number of previous spontaneous abortions was associated with increased odds of patients having experienced pre-eclampsia (adjusted odds ratio 1.28, 95% confidence interval 1.03-1.59; P=0.025). A history of spontaneous abortion was associated with increased odds of pre-eclampsia during a subsequent pregnancy. © 2016 International Federation of Gynecology and Obstetrics.

    To evaluate prenatal corticosteroid use in women experiencing spontaneous preterm labor and preterm delivery. The present cross-sectional multicenter study analyzed interview data from patients attending 20 hospitals in Brazil owing to preterm delivery between April 1, 2011 and July 30, 2012. Patients were stratified based on preterm delivery occurring before 34 weeks or at 34-36 +6  weeks of pregnancy, and the frequency of prenatal corticosteroid use at admission was compared. Prenatal corticosteroid use, sociodemographic data, obstetric characteristics, and neonatal outcomes were examined. There were 1455 preterm deliveries included in the present study; 527 (36.2%) occurred before 34 weeks of pregnancy and prenatal corticosteroids were used in 285 (54.1%) of these pregnancies. Among neonates delivered at 32-33 +6  weeks, prenatal corticosteroid use was associated with lower pneumonia (P=0.026) and mortality (P=0.029) rates. Among neonates delivered at 34-36 +6  weeks, prenatal corticosteroid use was associated with longer neonatal hospital admission (Pprenatal corticosteroids. This could reflect a sub-optimal interval between administration and delivery. © 2017 International Federation of Gynecology and Obstetrics.

    Triclosan (TCS), an antibacterial agent, is identified in serum and urine of humans. Here, we show that the level of urinary TCS in 28.3% patients who had spontaneous abortion in mid-gestation were increased by 11.3-fold (high-TCS) compared with normal pregnancies. Oral administration of TCS (10 mg/kg/day) in mice (TCS mice) caused an equivalent urinary TCS level as those in the high-TCS abortion patients. The TCS-exposure from gestation day (GD) 5.5 caused dose-dependently fetal death during GD12.5-16.5 with decline of live fetal weight. GD15.5 TCS mice appeared placental thrombus and tissue necrosis with enhancement of platelet aggregation. The levels of placenta and plasma estrogen sulfotransferase (EST) mRNA and protein in TCS mice or high-TCS abortion patients were not altered, but their EST activities were significantly reduced compared to controls. Although the levels of serum estrogen (E2) in TCS mice and high-TCS abortion patients had no difference from controls, their ratio of sulfo-conjugated E2 and unconjugated E2 was reduced. The estrogen receptor antagonist ICI-182,780 prevented the enhanced platelet aggregation and placental thrombosis and attenuated the fetal death in TCS mice. The findings indicate that TCS-exposure might cause spontaneous abortion probably through inhibition of EST activity to produce placental thrombosis.

    Preterm birth is the leading cause of newborn death worldwide, and is associated with significant cognitive and physiological challenges in later life. There is a pressing need to define the mechanisms that initiate spontaneous preterm labor, and for development of novel clinical biomarkers to identify high-risk pregnancies. Most preterm birth studies utilize fetal tissues, and there is limited understanding of the transcriptional changes that occur in mothers undergoing spontaneous preterm labor. Earlier work revealed that a specific population of maternal peripheral leukocytes (macrophages/monocytes) play an active role in the initiation of labor. Thus, we hypothesized that there are dynamic gene expression changes in maternal blood leukocytes during preterm labor. Using next-generation sequencing we aim to characterize the transcriptome in whole blood leukocytes and peripheral monocytes of women undergoing spontaneous preterm labor compared to healthy pregnant women who subsequently delivered at full term. RNA sequencing was performed in both whole blood and peripheral monocytes from women who underwent preterm labor (24-34 weeks of gestation, N = 20) matched for gestational age to healthy pregnant controls (N = 30). All participants were a part of the Ontario Birth Study cohort (Toronto, Ontario, Canada). We identified significant differences in expression of 262 genes in peripheral monocytes and 184 genes in whole blood of women who were in active spontaneous preterm labor compared to pregnant women of the same gestational age not undergoing labor, with 43 of these genes differentially expressed in both whole blood and peripheral monocytes. ADAMTS2 expression was significantly increased in women actively undergoing spontaneous preterm labor, which we validated through digital droplet reverse transcriptase polymerase chain reaction. Intriguingly, we have also identified a number of gene sets including signaling by stem cell factor-KIT, nucleotide metabolism

    Full Text Available The liver X receptors (LXRs have been shown to be crucially involved in maternal-fetal cholesterol transport and placentation. The aim of this study was to investigate the expression pattern and frequency of LXR under normal physiological circumstances and in spontaneous abortion and/or recurrent miscarriage. A total of 29 (12 physiologic pregnancies/10 spontaneous abortions/7 recurrent miscarriages human pregnancies in first trimester were analysed for LXR expression. Expression changes were evaluated by immunohistochemistry for receptor and quantitative RT-PCR (TaqMan was performed to determine the level of LXR mRNA expression. We also stained for RXRα and PPARγ as possible heterodimers of LXR. LXR expression was downregulated in the syncytiotrophoblast of spontaneous abortion placentas compared to normal pregnancy. In recurrent miscarriage there was a trend for a downregulation. Decidua showed an even stronger downregulation in both groups. In the syncytiotrophoblast we found a positive correlation for the combination of LXR/PPARγ in abortions and a negative correlation for LXR/RXRα. In addition, double-immunofluorescence staining showed that LXR as well as RXRα and PPARγ are expressed by the extravillous trophoblast. Finally, RXRα and LXR showed coexpression in the same extravillous trophoblast cells. To conclude, our data show that LXR expression is decreased in miscarriage.

    Morphologic changes in the placental barrier in spontaneous early abortions under the maternal-embryonic immune conflict, and the role of maternal immunoglobulins (Igs) in these changes. We examined chorionic villi and other tissues obtained from 54 aborts between weeks 3.5 and 8 of pregnancy. Material was divided into two groups. Group 1 (control) contained 15 medically recommended and spontaneous early aborts with no signs of inflammations or pathologic immune processes. Group 2 contained 39 spontaneous early aborts with acute chorionic villitis. Immunohistochemical and morphometric methods were used to study the Igs, different types of immunocompetent cells, and apoptosis-related components of the placental barrier. Acute villitis was found to be characterized by the destruction of all components of the chorionic villi, thrombovasculitis with apoptosis of the endothelium of capillaries and erythroblasts, mucous swelling of the basal membrane, and coagulation of the blood proteins. Due to destruction of the capillaries, the number of avasculate villi increased, and the average number of capillaries per villus decreased. The extremely high number of phagolysosomes with IgG and IgA in the villous monocytes in the group 2 indicates an increase in the phagocytic activity of monocytes against maternal Igs and may reflect the presence of mother-embryo immune conflict. Apoptosis of monocytes and a high number of promonocytes were seen accompanied by a high concentration of p53 protein. A large disturbance in the trophoblast occurred with disappearance of bcl-2 and the appearance of Fas ligand. Massive destruction of maternal Igs in embryonic monocytes and acute villitis in the placental barrier are manifested during the mother-embryo immune conflict, and this may be one of the reasons of spontaneous early abortions.

    abortion risk include biochemical assays as well as life table technique, although the latter appears in two different forms. The consequences of using either of these are discussed. It is concluded that no study design so far is appropriate for measuring the total risk of spontaneous abortion from early...... conception to the end of the 27th week. It is proposed that pregnancy may be considered to consist of two or three specific periods and that different study designs should concentrate on measuring the conditional risk within each period. A careful estimate using this principle leads to an estimate of total...

From a cohort of 1,405,663 pregnancies, oral fluconazole-exposed pregnancies were compared with up to 4 unexposed pregnancies matched on propensity score, maternal age, calendar year, and gestational age (based on gestational age at first day of treatment with eligible controls surviving through this date). To test for confounding by indication, pregnancies exposed to intravaginal formulations of topical azoles were used as an additional comparator group. Filled prescriptions for oral fluconazole were obtained from the National Prescription Register. Hazard ratios (HRs) for spontaneous abortion and stillbirth, estimated using proportional hazards regression. Among 3315 women exposed to oral fluconazole from 7 through 22 weeks' gestation, 147 experienced a spontaneous abortion, compared with 563 among 13,246 unexposed matched women. There was a significantly increased risk of spontaneous abortion associated with fluconazole exposure (HR, 1.48; 95% CI, 1.23-1.77). Among 5382 women exposed to fluconazole from gestational week 7 to birth, 21 experienced a stillbirth, compared with 77 among 21,506 unexposed matched women. There was no significant association between fluconazole exposure and stillbirth (HR, 1.32 [95% CI, 0.82-2.14]). Using topical azole exposure as the comparison, 130 of 2823 women exposed to fluconazole vs 118 of 2823 exposed to topical azoles had a spontaneous abortion (HR, 1.62 [95% CI, 1.26-2.07]); 20 of 4301 women exposed to fluconazole vs 22 of 4301 exposed to topical azoles had a stillbirth (HR, 1.18 [95% CI, 0.64-2.16]).

    This study aimed to understand women's pathways of seeking care for postabortion complications in Madhya Pradesh, India. The study recruited 786 women between July and November 2007. Data were collected on service provision, abortion-related complications, care-seeking behavior, knowledge about abortion legality and availability, methods used, symptoms, referral source, and out-of-pocket costs. Women seeking care for complications from induced abortion followed more complex pathways to treatment than women with complications of spontaneous abortion. More complex pathways were associated with higher out-of-pocket costs. Improving community awareness on legal aspects, safe abortion methods, and trained providers are necessary to reduce morbidity associated with unsafe abortion.

    The objective of this study was to create sexual history profiles of women with illegally induced abortion (IA) and women with spontaneous abortion (SA) and describe the women's knowledge of, attitude to, and practice of contraception. The study was carried out in two settings, Temeke District...... Hospital (TDH) and Muhimbili Medical Centre (MMC) in Dar es Salaam. At TDH 362/603 (60 per cent) were identified as IA and 241/603 (40 per cent) as SA. At MMC the figures were 68/220 (31 per cent) IA and 152/220 (69 per cent) SA. Both groups were well informed about modern contraception. As a contrast...... the rate of ever users of contraception was low in both groups, although significantly lower among IA women than among SA women. Outcome of first pregnancy had been an induced abortion in significantly higher proportion of IA than of SA women. In conclusion, sexual intercourse before marriage is common...

    Full Text Available ACP1 (low molecular weight acid phosphatase genetic polymorphism has been studied in 173 women with a history of two or more consecutive spontaneous abortions and in 1508 control subjects, including 482 normal pregnant women. The proportion of carriers of ACP1 *C allele (* A/ *C, *B/*C in women with a history of repeated spontaneous abortion is lower than in normal pregnant women and other control groups, Women with repeated spontaneous abortion show a specific decrease of ACPI S isoform concentration as compared to normal pregnant women, The other component of ACP I activity, the F isoform, does not show a significant difference between the two groups. The data suggest that women with ACP1 genotypes showing a high concentration of S isoform are relatively 'protected' against spontaneous abortion, Preliminary analysis of a sample of 352 normal puerperae along with their newborn babies supports this hypothesis,

    When administered inappropriately, first-trimester misoprostol management of induced or spontaneous abortion can result in loss or damage of a continuing pregnancy. Despite these serious consequences, such misoprostol exposures continue to occur. Unfortunately, contributing factors and preventive measures receive little attention. We describe the cases of 4 women in whom misoprostol was inappropriately administered during management of induced and presumed spontaneous abortion. In each case, careful adherence to published clinical guidance could have avoided the exposures. © 2017 Wiley Periodicals, Inc.

    BACKGROUND: Consumption of caffeine and alcohol is suspected to affect pregnancy outcome. Use of both stimulants is widespread and even minor effects on fetal viability are of public health interest. METHODS: We performed a nested case-control study using prospective data from a population......-based cohort comprising 11088 women aged 20-29 years. From this cohort, women who experienced either a spontaneous abortion (n = 303) or who gave birth (n = 1381) during follow-up [mean time: 2.1 years (range: 1.6-3.4)] were selected. Associations between self-reported exposures to caffeine and/or alcohol...... at enrolment and spontaneous abortion were analysed by means of logistic regression. RESULTS: Compared with women with a pre-pregnancy intake of caffeine per day, the adjusted odds ratio (95% confidence interval) for spontaneous abortion was 1.26 (0.77-2.06), 1.45 (0.87-2.41), 1.44 (0.87-2.37) and 1...

    A study was conducted to determine whether the incidence of spontaneous abortion was greater than expected near the Three Mile Island (TMI) nuclear power plant during the months following the March 28, 1979 accident. All persons living within five miles of TMI were registered shortly after the accident, and information on pregnancy at the time of the accident was collected. After one year, all pregnancy cases were followed up and outcomes ascertained. Using the life table method, it was found that, given pregnancies after four completed weeks of gestation counting from the first day of the last menstrual period, the estimated incidence of spontaneous abortion (miscarriage before completion of 16 weeks of gestation) was 15.1 per cent for women pregnant at the time of the TMI accident. Combining spontaneous abortions and stillbirths (delivery of a dead fetus after 16 weeks of gestation), the estimated incidence was 16.1 per cent for pregnancies after four completed weeks of gestation. Both incidences are comparable to baseline studies of fetal loss.

    Full Text Available Varicocele is still an enigma. Its effects on semen analysis, fertility and, more re-cently, early ejaculation and spontaneous abortion in spouses are not yet fully understood. In this retrospective study, we evaluated these four parameters (semen analysis, fertility, early ejacu-lation and spontaneous abortion among spouses in relation to varicocele and varicocelectomy during a 13-year period. A total of 1,711 patients with varicocele underwent varicocelectomy by high inguinal method (251 cases, subinguinal method (1,375 cases, scrotal method (34 cases, and subinguinal method with local anesthesia (38 cases. Our complication rate was acceptable. Sperm count, motility and morphology increased three months post operation in 55, 51, and 46%, respectively (P value 0.000, 0.000, and 0.015, respectively. Paternity was 56% after one year of post varicocelectomy follow-up. Only 7 out of 82 azoospermic men had sperm in their semen after varicocelectomy and only one of them with mild spermatogenic hypoplasia became a father. The spontaneous abortion rate in the spouses of respondents was 59%. Early ejaculation improved in 75% of the respondents. In conclusion, varicocelectomy does not improve sperm parameters in all men, but it improves pregnancy rate, early ejaculation, and scrotal pain.

    Full Text Available Spontaneous preterm birth significantly contributes to the overall neonatal morbidity associated with preterm deliveries. Nearly 50% of cases are associated with microbial invasion of the amniotic cavity followed by an inflammatory response. Robust diagnostic tools for neonates jeopardized by infection and inflammation may thus decrease the overall neonatal morbidity substantially. Amniotic fluid retrieved during labor retains fetal and pregnancy-related protein fingerprint and its sampling does not place any unwanted stress on women. Using exploratory and targeted methods we analyzed proteomes of amniotic fluid sampled at the end of spontaneous preterm labor prior to delivery from women with and without infection and inflammation. Exploratory data indicated several amniotic fluid proteins to be associated with infectious-inflammatory complications in spontaneous preterm birth. LC-SRM analysis subsequently verified statistically significant changes in lipocalin-1 (P=0.047 and AUC = 0.67, P=0.046, glycodelin (P=0.013 and AUC = 0.73, P=0.013, and nicotinamide phosphoribosyltransferase (P=0.018 and AUC = 0.71, P=0.01.

    Experimental research of drug safety in pregnancy is generally not feasible because of ethical issues. Therefore, most of the information about drug safety in general and teratogenicity in particular is obtained through observational studies, which require careful methodologic design to obtain unbiased results. Immortal time bias occurs when some cases do not "survive" sufficient time in the study, and as such, they have reduced chances of being defined as "exposed" simply because the durations of their follow-ups were shorter. For example, studies that examine the risk for spontaneous abortions in women exposed to a drug during pregnancy are susceptible to immortal time bias because the chance of drug exposure increases the longer a pregnancy lasts. Therefore, the drug tested may falsely be found protective against the outcome tested. The objective of the current study was to illustrate the extent of immortal time bias using a cohort study of pregnancies assessing the risk for spontaneous abortions following nonsteroidal antiinflammatory drug exposure. We assembled 3 databases containing data on spontaneous abortions, births and drug dispensions to create the present study's cohort. The risk for spontaneous abortion was assessed using 2 statistical analysis methods that were compared for 2 definitions of exposure (dichotomous, exposed vs unexposed, regular Cox regression vs Cox regression with time-varying exposure). Significant differences were found in the risk for spontaneous abortions between the 2 statistical methods, both for groups and for most specific nonsteroidal antiinflammatory drugs (nonselective Cox inhibitors - hazard ratio, 0.70; 95% confidence interval, 0.61-0.94 vs hazard ratio, 1.10; 95% confidence interval, 0.99-1.22 for dichotomous vs time-varying exposure analyses, respectively). Furthermore, a significant correlation was found between the median misclassified immortal time for each drug and the extent of the bias. Immortal time bias can

    BACKGROUND The aim of this study was to evaluate the association of maternal serum 25-hydroxyvitamin D, paraoxonase 1, and neutrophil-to-lymphocyte ratio in women having early spontaneous preterm birth without clinical chorioamnionitis. MATERIAL AND METHODS This study was prospectively administered in women referred to our obstetrics service with preterm labor that resulted in preterm birth (n=35) and term labor that ended in term birth (n=44). The maternal serum levels of 25-hydroxyvitamin D and paraoxonase 1 were measured and neutrophil-to-lymphocyte ratio was calculated. RESULTS The 25-hydroxyvitamin D and paraoxonase 1 levels of the preterm group were significantly lower than those of the term group (pparaoxonase 1 in the preterm group (r=0.35; p=0.021). CONCLUSIONS Decreased maternal serum 25-hydroxyvitamin D and paraoxonase 1 levels and increased neutrophil-to-lymphocyte ratio may have a role in the etiology of spontaneous preterm birth.

    Information about the recurrence of spontaneous preterm birth in subsequent twin/singleton pregnancies is scattered. To quantify the risk of recurrence of spontaneous preterm birth in different subtypes of subsequent pregnancies. An electronic literature search in OVID MEDLINE and EMBASE, complemented by PubMed, to find recent studies. Studies comparing the risk of spontaneous preterm birth after a previous preterm and previous term pregnancy. The absolute risk of recurrence with a 95% confidence interval and the absolute risk of preterm birth after a term delivery were calculated. Data from studies were pooled using the Mantel-Haenszel method. We detected 13 relevant studies. The risk of recurrence of preterm birth was significantly increased in all preterm pregnancy subtypes, compared with their term counterparts. Women pregnant with twins after a previous preterm singleton had the highest absolute risk of recurrence (57.0%, 95% CI 51.9-61.9%), and after a previous term singleton their absolute risk was 25% (95% CI 24.3-26.5%). Women pregnant with a singleton after a previous preterm twin pregnancy have an absolute recurrence risk of 10% (95% CI 8.2-12.3%), whereas a singleton pregnancy after delivering a previous twin up to term yields a low absolute risk of only 1.3% (95% CI 0.8-2.2). Women pregnant with a singleton after a previous preterm singleton have an absolute recurrence risk of 20% (95% CI 19.9-20.6). The risk of recurrence of preterm birth is influenced by the singleton/twin order in both pregnancies, and varies between 10% for a singleton after previous preterm twins to 57% for twins after a previous preterm singleton. © 2014 Royal College of Obstetricians and Gynaecologists.

    To investigate the independent impact of prepregnancy obesity on preterm delivery among women without chronic diseases by gestational age, preterm category and parity. A retrospective cohort study. Data from the Consortium on Safe Labor (CSL) in the USA (2002-08). Singleton deliveries at ≥23 weeks of gestation in the CSL (43 200 nulliparas and 63 129 multiparas) with a prepregnancy body mass index (BMI) ≥18.5 kg/m 2 and without chronic diseases. Association of prepregnancy BMI and the risk of preterm delivery was examined using Poisson regression with normal weight as reference. Preterm deliveries were categorised by gestational age (extremely, very, moderate to late) and category (spontaneous, indicated, no recorded indication). Relative risk of spontaneous preterm delivery was increased for extremely preterm among obese nulliparas (1.26, 95% CI: 0.94-1.70 for overweight; 1.88, 95% CI: 1.30-2.71 for obese class I; 1.99, 95% CI: 1.32-3.01 for obese class II/III) and decreased for moderate to late preterm delivery among overweight and obese multiparas (0.90, 95% CI: 0.83-0.97 for overweight; 0.87, 95% CI: 0.78-0.97 for obese class I; 0.79, 95% CI: 0.69-0.90 for obese class II/III). Indicated preterm delivery risk was increased with prepregnancy BMI in a dose-response manner for extremely preterm and moderate to late preterm among nulliparas, as it was for moderate to late preterm delivery among multiparas. Prepregnancy BMI was associated with increased risk of preterm delivery even in the absence of chronic diseases, but the association was heterogeneous by preterm categories, gestational age and parity. Obese nulliparas without chronic disease had higher risk for spontaneous delivery <28 weeks of gestation. © 2017 Royal College of Obstetricians and Gynaecologists.

    The present study is aimed to explore the relationship between aberrant expression of heat shock protein 70 (HSP) and spontaneous abortion. 50 patients with spontaneous abortion and 50 patients with induced abortion were continuously selected based on the nearest matching principle, and the proportion of age and gestational age was 1:1. The decidual tissues were obtained, and the cell apoptosis was determined by TUNEL assay. Further, the expression of HSP70 was assayed by immune-histochemical staining, and the expression of HSP70 mRNA was detected by the RT-PCR approach. Apoptosis rate, HSP70 expression and HSP70 mRNA expression in the observation group were significantly higher than the control group. HSP70 might induce apoptosis so as to cause spontaneous abortion.

    Full Text Available Bovine Herpesvirus type 5 (BoHV-5 has not been conclusively demonstrated to cause bovine abortion. Brain lesions produced by Neospora caninum and Bovine Herpesvirus type 1 (BoHV-1 exhibit common features. Therefore, careful microscopic evaluation and additional diagnostic procedures are required to achieve an accurate final etiological diagnosis. The aim of the present work was to investigate the occurrence of infections due to BoHV-1, BoHV-5 and N. caninum in 68 cases of spontaneous bovine abortions which showed microscopic lesions in the fetal central nervous system. This study allowed the identification of 4 (5.9% fetuses with dual infection by BoHV-5 and N. caninum and 33 (48.5% cases in which N. caninum was the sole pathogen identified. All cases were negative to BoHV-1. The results of this study provide evidence that dual infection by BoHV-5 and N. caninum occur during pregnancy in cattle; however, the role of BoHV-5 as a primary cause of bovine abortion needs further research. Molecular diagnosis of BoHV-5 and N. caninum confirmed the importance of applying complementary assays to improve the sensitivity of diagnosing bovine abortion.

    2017-07-14

    Preterm birth (birth before 37 weeks of gestation) is a major problem in obstetrics and affects an estimated 15 million pregnancies worldwide annually. A history of previous preterm birth is the strongest risk factor for preterm birth, and recurrent spontaneous preterm birth affects more than 2.5 million pregnancies each year. A recent meta-analysis showed possible benefits of the use of low dose aspirin in the prevention of recurrent spontaneous preterm birth. We will assess the (cost-)effectiveness of low dose aspirin in comparison with placebo in the prevention of recurrent spontaneous preterm birth in a randomized clinical trial. Women with a singleton pregnancy and a history of spontaneous preterm birth in a singleton pregnancy (22-37 weeks of gestation) will be asked to participate in a multicenter, randomized, double blinded, placebo controlled trial. Women will be randomized to low dose aspirin (80 mg once daily) or placebo, initiated from 8 to 16 weeks up to maximal 36 weeks of gestation. The primary outcome measure will be preterm birth, defined as birth at a gestational age (GA) aspirin is effective in preventing preterm birth, we expect that there will be cost savings, because of the low costs of aspirin. To evaluate this, a cost-effectiveness analysis will be performed comparing preventive treatment with aspirin with placebo.

    Spontaneous movements at 2 months of corrected age in preterm infants with intellectual disability (ID) were investigated by assessing individual motor elements separated from movements involving the entire body. Video recordings of 20 preterm infants with ID (16 males, 4 females; median gestational age 26 weeks; median birth weight 810 g) were analyzed and were compared with those of 21 normal preterm infants (8 males, 13 females; median gestational age 30 weeks; median birth weight 1216 g). In the preterm infants with ID at 2 months corrected age, startle response, lateral decumbent position, predominant shoulder rotation, and maintaining hip adduction were more frequently observed and hand sucking, maintaining shoulder abduction, to-and-fro shoulder abduction, to-and-fro elbow flexion, isolated hip adduction, to-and-fro hip abduction, and leg lift were less frequently seen than in the normal preterm infants (Fisher's exact test, ppreterm infants with ID result from persistent immature movements and non-emergence of mature movements.

    The objectives of this pilot study were to assess the potential use of 3D videography for analyzing the motion of the body center of mass (COM) in newborns and to determine differences in spontaneous movements between preterm and full-term infants. The group comprised 10 preterm newborns (gestational age at birth between 26 and 37 weeks; birth weight 800 to 2960 g; gestational age at the time of examination 34 to 39 weeks) and 10 full-term infants (gestational week 38 to 41; birth weight 2810 to 4360 g). To determine the range of motion of the COM, 3D videography was used (2 cameras, 25 Hz). When recording their movements, the infants were in the supine position, calm and awake. The recordings were processed using the APAS software. Selected points on the body were marked to obtain data for calculating the basic parameters of COM trajectories. The range of motion of the COM in both craniocaudal and anteroposterior directions was significantly greater in premature infants (P preterm babies. This was also valid for the velocity of motion of the COM in the craniocaudal direction (P preterm infants. Basic kinematic characteristics of the motion of the COM (range, variability, velocity) are greater in preterm infants.

    IgG anticardiolipin antibodies (ACL) have been shown to occur in a high proportion of women with repeated unexplained miscarriages. Forty-nine women with unexplained recurrent spontaneous abortions (RSA), previously assayed for the presence of ACL by an enzyme-linked immunoabsorbent assay, were typed for HLA-DR and DQ antigens by the classical microlymphocytotoxicity test. Twenty-five women were positive for ACL and 24 were negative. HLA-DR7 was found in 24.5% of 49 habitually aborting women vs. 28% of healthy controls; but the DR7 frequency was 40% in ACL positive patients vs. 8.3% in ACL negative patients (P = 0.011). These results show that in the Italian population an association between HLA-DR7 antigen and ACL is present in women with unexplained RSA, suggesting that HLA-DR genes might control the susceptibility to specific autoantibody production.

    Objective. The purpose of this study was to (i) determine the cervical microbial composition in different abortion samples and to (ii) investigate the correlation between spontaneous abortion and cervical microbes in Korean women. Methods. We collected cervical swabs from women who had never undergone abortion ( N = 36), had spontaneous abortion ( N = 23), and had undergone induced abortion ( N = 88) and subjected those samples to 16S rRNA pyrosequencing. Further, factor analysis and correlation between cervical microbiota and spontaneous abortion were evaluated by logistic regression analysis. Results. In spontaneous abortion women, 16 S rRNA gene sequences showed significant increases in Atopobium vaginae , Megasphaera spp., Gardnerella vaginalis , Leptotrichia amnionii , and Sneathia sanguinegens compared to women in nonabortion group. In multivariate logistic regression analysis, A. vaginae (OD = 11.27; 95% = 1.57-81) , L. amnionii (OD = 11.47; 95% = 1.22-107.94), S. sanguinegens (OD = 6.89; 95% = 1.07-44.33), and factor 1 microbes (OD = 16.4; 95% = 1.88-42.5) were strongly associated with spontaneous abortion. Conclusions. This study showed a high prevalence of L. amnionii, A. vaginae, S. sanguinegens , and factor 1 microbes in spontaneous abortion and association with spontaneous abortion in Korean women.

    Preterm neonates are highly susceptible to infection. Neonatal host defense against infection seems to be maintained by the temporal presence of immunosuppressive CD71+ erythroid cells. The aim of this study was to investigate whether umbilical cord CD71+ erythroid cells are reduced in neonates born to women who undergo spontaneous preterm labor/birth. Umbilical cord blood samples (n=155) were collected from neonates born to women who delivered preterm with (n=39) and without (n=12) spontaneous labor or at term with (n=82) and without (n=22) spontaneous labor. Time-matched maternal peripheral blood samples were also included (n=111). Mononuclear cells were isolated from these samples, and CD71+ erythroid cells were identified and quantified as CD3-CD235a+CD71+ cells by flow cytometry. (i) The proportion of CD71+ erythroid cells was 50-fold higher in cord blood than in maternal blood; (ii) a reduced number and frequency of umbilical cord CD71+ erythroid cells were found in neonates born to women who underwent spontaneous preterm labor compared to those born to women who delivered preterm without labor; (iii) umbilical cord CD71+ erythroid cells were fewer in neonates born to term pregnancies, regardless of the process of labor, than in those born to women who delivered preterm without labor; and (iv) no differences were seen in umbilical cord CD71+ erythroid cells between neonates born to women who underwent spontaneous preterm labor and those born to women who delivered at term with labor. Umbilical cord CD71+ erythroid cells are reduced in neonates born to women who had undergone spontaneous preterm labor. Published 2016.

    2004-02-01

    Full Text Available Abstract The pathogenesis of human spontaneous abortion involves a complex interaction of several genetic and environmental factors. The firm association between increased homocysteine concentration and neural tube defects (NTD has led to the hypothesis that high concentrations of homocysteine might be embryotoxic and lead to decreased fetal viability. There are several genetic polymorphisms that are associated with defects in folate- and vitamin B12-dependent homocysteine metabolism. The methylenetetrahydrofolate reductase (MTHFR 677C>T and 1298A>C polymorphisms cause elevated homocysteine concentration and are associated with an increased risk of NTD. Additionally, low concentration of vitamin B12 (cobalamin or transcobalamin that delivers vitamin B12 to the cells of the body leads to hyperhomocysteinemia and is associated with NTD. This effect involves the transcobalamin (TC 776C>G polymorphism. Importantly, the biochemical consequences of these polymorphisms can be modified by folate and vitamin B12 supplementation. In this review, I focus on recent studies on the role of hyperhomocysteinemia-associated polymorphisms in the pathogenesis of human spontaneous abortion and discuss the possibility that periconceptional supplementation with folate and vitamin B12 might lower the incidence of miscarriage in women planning a pregnancy.

    Spontaneous abortion is the most common complication of pregnancy. Immune activation and the subsequent inflammation-induced tissue injury are often observed at the maternal-fetal interface as the final pathological assault in recurrent spontaneous abortion. However, the precise mechanisms responsible for spontaneous abortion involving inflammation are not fully understood. Chemokine CCL28 and its receptors CCR3 and CCR10 are important regulators in inflammatory process. Here, we examined the expression of CCL28 and its receptors in decidual stromal cells (DSCs) by immunochemistry and flow cytometry (FCM), and compared their expression level in DSCs from normal pregnancy versus spontaneous abortion, and their relationship to inflammatory cytokines production by DSCs. We further analyzed regulation of the pro-inflammatory cytokines on CCL28 expression in DSCs by real-time polymerase chain reaction, In-cell Western and FCM. The effects of CCL28-CCR3/CCR10 interaction on DSC apoptosis was investigated by Annexin V staining and FCM analysis or DAPI staining and nuclear morphology. Higher levels of the inflammatory cytokines interleukin (IL)-1β, IL-17A and tumor necrosis factor-α, and increased CCR3/CCR10 expression were observed in DSCs from spontaneous abortion compared with normal pregnancy. Treatment with inflammatory cytokines differently affected CCL28 and CCR3/CCR10 expression in DSCs. Human recombinant CCL28 promoted DSC apoptosis, which was eliminated by pretreatment with neutralizing antibodies against CCR3/CCR10 and CCL28. However, CCL28 did not affect DSC growth. These results suggest that the inflammation-promoted up-regulation of CCL28 and its receptors interaction in DSCs is involved in human spontaneous abortion via inducing DSC apoptosis.

    Approximately 205 million pregnancies occur each year in the worldwide. On the other hand, Spontaneous abortion has been reported in 15-20% of all diagnosed pregnancies. The most common cause of spontaneous abortion is chromosomal abnormalities of the embryo. Robertsonian translocation carriers specially 21-14 are the most common balanced rearrangement among the carrier couples with the history of spontaneous abortion. In order to search for balanced chromosomal rearrangement and cytogenetic disorders, 10 members of related family with consanguinity marriage with the history of recurrent miscarriage were assessed. Cytogenetic evaluation on the basis G-banding technique at high resolution was performed in 3 couples and their related family with the history of idiopathic RSA in order to postulate any balanced chromosomal rearrangement. six members of them appeared with robertsonian balanced translocation between chromosome No.21 to No. 14 with the karyotype of 45, XX, t (14, 21) and 45, XY, t (14, 21), which this results are in agreement with several similar works which claimed that the risk of spontaneous abortion in couples with balanced chromosomal rearrangements is higher compared with general population. Considering to results of present study, it seems as if the cytogenetic analysis of couples with the history of recurrent abortions should be suggested compulsory to estimate the probable presence of any chromosomal rearrangement. This offer wills valuable information for genetic consulting.

    Aim of this study was to determine the intrauterine activity of matrix metalloproteinases (MMP)-2 and -9 after cessation of the local effect of progesterone. For this purpose, pregnancy was terminated in 10 bitches at mid-gestation with the progesterone receptor antagonist aglepristone (10 mg/kg body weight, sc, Alizine®; Virbac, France) at two subsequent days (group IRA = induced resorption/abortion). The IRA group was divided into two subgroups (Group I, n = 5, days 25-35 of pregnancy; group II, n = 5, days 36-45). Five further bitches were introduced with beginning abortion (group SRA = spontaneous resorption/abortion). Seven healthy bitches between day 25 and 45 of gestation served as controls. After ovariohysterectomy at the end of abortion and between days 25 and 45 of gestation, respectively, the distribution and activity of collagenases were investigated by immunohistochemistry and gelatin zymography. At placental sites, MMP-2 activity in the endometrium was significantly lower in IRA groups than in the SRA group (33.7 ± 11.8% and 39.3 ± 5.4% vs 52.2 ± 10.2%, p < 0.05); however, MMP-2 expression was lowest in the control group (control: 21.4 ± 6.3%; p < 0.01) and similarly in the myometrium (controls: 13.1 ± 2.5%; p < 0.05). MMP-9 activity was also lower in the endometrium and myometrium of the control group in comparison to SRA and IRA groups (11.8 ± 3.2%; p < 0.01 and 28.4 ± 32.8%; p < 0.05). At interplacental sites, the amount of active collagenases in the myometrium was significantly lower in the control group. It is concluded that the blockade of the biological progesterone effect was associated with an increase in activity of both collagenases. © 2010 Blackwell Verlag GmbH.

    To determine whether use of antiepileptic drugs during pregnancy may increase the risk of spontaneous abortion or stillbirth. Population based cohort study. Register based study in Denmark, 1997-2008. 983,305 pregnancies identified in the Danish medical birth register and the Danish national hospital discharge register from 1 February 1997 to 31 December 2008 were linked to the Danish Register of Medicinal Product Statistics to obtain information on use of antiepileptic drugs. Risk ratio of spontaneous abortion and stillbirth after use of antiepileptic drugs during pregnancy, estimated by using binomial regression adjusting for potential confounders of maternal age, cohabitation, income, education, history of severe mental disorder, and history of drug misuse. Antiepileptic drugs were used in a total of 4700 (0.5%) pregnancies. 16 out of 100 pregnant women using antiepileptics and 13 out of 100 pregnant women not using antiepileptics experienced a spontaneous abortion. After adjusting for potential confounders pregnant women using antiepileptics had a 13% higher risk of spontaneous abortions than pregnant women not using antiepileptics (adjusted risk ratio 1.13, 95% confidence interval 1.04 to 1.24). However, the risk of spontaneous abortion was not increased in women with an epilepsy diagnosis (0.98, 0.87 to 1.09), only in women without a diagnosis of epilepsy (1.30, 1.14 to 1.49). In an analysis including women with at least two pregnancies with discordant antiepileptic drug use (for example, use in the first pregnancy but not in the second), the adjusted hazard ratio for spontaneous abortion was 0.83 (0.69 to 1.00) for exposed pregnancies compared with unexposed pregnancies. Stillbirth was identified in 18 women who used antiepileptic drugs (unadjusted risk ratio 1.29, 0.80 to 2.10). Among women with epilepsy and when analysing the risk in antiepileptic drug discordant pregnancies in the same woman, we found no overall association between the use of

    The aim of our study is to determine prevalence and clinical significance of the presence of amniotic fluid "sludge" among asymptomatic patients at high-risk for spontaneous preterm delivery, prospectively. In our study, 99 patients at high risk for spontaneous preterm delivery were evaluated for the presence of amniotic fluid sludge with transvaginal ultrasonography at 20-22, 26-28, and 32-34 gestational weeks, prospectively; between August 2009 and October 2010 in Hacettepe University Hospital. And, these patients were followed up for their delivery weeks and pregnancy outcomes. We defined the high-risk group as the patients possessing one or more of the followings; a history of spontaneous preterm delivery, recent urinary tract infections, polyhydramnios, uterine leiomyomas, müllerian duct anomalies, and history of cone biyopsy or LEEP. Patients with multiple gestations, placenta previa, fetal anomalies, or symptoms of preterm labor at first examination were excluded. We have obtained ethical board approval from Hacettepe University (16.07.2009-HEK/No:09-141-59). The prevalence of amniotic fluid sludge in the study population was 19,6% (18/92). The rates of spontaneous preterm delivery at preterm delivery (p = 0.002). A higher proportion of neonates born to patients with amniotic fluid sludge had a neonatal morbidity (50% (9/18) vs. 24,3% (18/74), p = 0.044) and died in the perinatal period, (p = 0,013) than those born to patients without sludge. When we combined sludge and cervical lenght (CL) (preterm delivery; it catched more women with preterm delivery, (p = 0.000). While sensitivity of sludge was 37,5%, and sensitivity of CL was 34%, sensitivity of "sludge positive or CL ≤25 mm" was 56% for preterm birth (PTB) in high-risk group. The prevalence of amniotic fluid sludge is 19,6% and "sludge" is an independent risk factor for spontaneous preterm delivery among asymptomatic patients at high-risk for spontaneous preterm delivery.

    Objective The aim of this study was to identify early proteomic biomarkers of spontaneous preterm delivery (PTD) in mid-trimester amniotic fluid from asymptomatic women. Methods This is a case-cohort study. Amniotic fluid from mid-trimester genetic amniocentesis (14–19 weeks of gestation) was collected from 2008 to 2011. The analysis was conducted in 24 healthy women with subsequent spontaneous PTD (cases) and 40 randomly selected healthy women delivering at term (controls). An exploratory phase with proteomics analysis of pooled samples was followed by a verification phase with ELISA of individual case and control samples. Results The median (interquartile range (IQR: 25th; 75th percentiles) gestational age at delivery was 35+5 (33+6–36+6) weeks in women with spontaneous PTD and 40+0 (39+1–40+5) weeks in women who delivered at term. In the exploratory phase, the most pronounced differences were found in C-reactive protein (CRP) levels, that were approximately two-fold higher in the pooled case samples than in the pooled control samples. However, we could not verify these differences with ELISA. The median (25th; 75th IQR) CRP level was 95.2 ng/mL (64.3; 163.5) in women with spontaneous PTD and 86.0 ng/mL (51.2; 145.8) in women delivering at term (p = 0.37; t-test). Conclusions Proteomic analysis with mass spectrometry of mid-trimester amniotic fluid suggests CRP as a potential marker of spontaneous preterm delivery, but this prognostic potential was not verified with ELISA.

    Preterm birth is the legal first global cause of neonatal death. The cervix has two roles: it has to stay closed to allow the fetus to undergo a normal development during gestation, and at term, the cervix has to dilate under the pressure of uterine contractions to allow the delivery. The purpose of this article is to establish if the ultrasound measured length of the cervix and its appearance are predictive for the spontaneous preterm birth. Cervical insufficiency can be described by painless cervical dilatation leading to pregnancy losses/ births, with no other risk factors present. During gestation, the physiological softening of the cervix is determined by the extracellular matrix components, particular decorin, and thrombospondin 2. The direction of the collagen fibers remains the same - circumferential direction, but the collagen solubility increases. Therefore, during pregnancy, the cervical tissue is more hydrated and has higher collagen extractability than non-pregnant tissue. Women with cervical incompetence have increased levels of smooth muscle cells than normal pregnant women, the number of elastic fibers is low, and also the concentration of hydroxyproline is decreased. Transvaginal ultrasound is the suitable gold standard exam that can offer essential information about the cervical length and state of the internal os in early asymptomatic stage of cervical insufficiency for predicting and preventing preterm birth. In our experience, a transvaginal ultrasound screening for the measurement of the cervix is required. We consider that the proper gestational age for the prediction of a preterm birth is at 18-22 weeks of gestation for the general population and earlier for patients with a history of preterm birth. Just from an observational point of view, we concluded with the fact that the cerclage of the cervix is unnecessary if the cervical length is above 2 cm and if the internal cervical os is closed. In the absence of funneling, the probability of

    The Weathering Effect is a theory that links stress exposure, over the life-course, with racial disparities in reproductive outcomes, through the effects of social adversity on a woman's body. The concept of maternal "weathering" captures cumulative somatic and psychological adversities that can exacerbate the effects of aging. Much of the evidence for weathering comes from observational studies linking self-report measures with reproductive outcomes. The purpose of this review is to explore biological mechanisms that underlie these observations. We focus on spontaneous abortion because this event is understudied despite evidence of racial disparities in this outcome. Spontaneous abortion is the most common pregnancy failure, and it happens early in pregnancy. Early pregnancy is a time most susceptible to the harmful effects of immune dysregulation that may, in part, result from adversities experienced before pregnancy begins. In exploring these mechanisms, we draw on well-defined signaling processes observed in the stressor-depression relationship. Pro-inflammatory dysregulation, for example, has particular relevance to immunological control occurring early in pregnancy. Early pregnancy immunologic changes affect the trajectories of pregnancy via control of trophoblastic invasion. Within the first few weeks of pregnancy, uterine derived cytokines operate within cytokine networks and play a critical role in this invasion. Programming for pro-inflammatory dysregulation can occur before conception. This dysregulation, brought into early pregnancy, has implications for viability and success of the index pregnancy. These patterns suggest early pregnancy health is susceptible to stress processing pathways that influence this immunologic control in the first six to eight weeks of pregnancy. In this review, we discuss the known mediating role of immune factors in the stressor-depression relationship. We also discuss how adversity experienced before the index pregnancy, or

    To identify clinical situations in which progestatives used to reduce the risk of spontaneous preterm delivery and/or reduced adverse neonatal outcomes have been evaluated and identify situations in which 17OHPC or vaginal progesterone might be recommended. Bibliographic searches were performed in the Medline and Cochrane databases with the use of a combination of keywords and text words related to "progesterone", "tocolysis", and "preterm labor" from 1956 through July 2016. 17OHPC administrated after 16 weeks gestational age is not associated with an increased risk of birth defect (LE3). Because of discrepancies on the risk associated with first trimester utilization, it is recommended not to use it before 16 weeks (grade C). Utilization of 17OHPC and vaginal progesterone during both second and third trimester is not associated with an increased risk of congenital abnormalities and developmental adverse outcomes (LE3). Utilization of progestatives is not associated with an increased risk of intrahepatic cholestasis of pregnancy (LE3) and gestational diabetes (LE3). 17OHPC is not recommended as a primary prevention of preterm delivery in a population of women with monofetal pregnancy without history of preterm delivery (grade C). Although systematic screening of short cervix is not recommended (Professional consensus), the discovery of a short cervix (<20mm) between 16 and 24 weeks in an asymptomatic woman with monofetal pregnancy without history of preterm delivery indicates the daily administration of vaginal progesterone until 36 weeks gestational age (grade B). In a randomized controlled trial, 17OHPC is associated with a decreased risk of preterm delivery before 34 weeks gestationnal age (LE2) and with a reduction of neonatal morbidity (LE3) in women with at least one previous preterm delivery before 34 weeks gestationnal age. It is not possible to recommend the systematic use of 17OHPC on the basis of this sole trial with limited external validity

    To better understand the correlation between Helicobacter pylori (H. pylori) seropositivity and spontaneous preterm birth. A total of 320 pregnant women were classified into two groups: normal control singleton pregnant group (n = 264) and singleton spontaneous preterm birth group (n = 56). Blood samples were collected at the time of delivery, and the H. pylori IgG, various virulence factors and systemic inflammation status were compared between the two groups. Between the two groups, the serum H. pylori IgG, Cytotoxin-associated agntigen A (Cag A), Vacuolating cytotoxin A (Vac A) significantly increased in spontaneous preterm birth group than in the control group. Also, in preterm group, highly sensitive C-reactive protein (hsCRP) as a systemic inflammatory marker is statistically elevated at inflammatory status range. Whereas in the term pregnant group, hsCRP was normal range even though high incidence of H. pylori IgG seropositivity. Also, in the seropositive group, hsCRP is statistically correlated with H. pylori IgG, Cag A and Vac A. There is an association between the presence of antibodies against H. pylori in maternal serum and the development of preterm birth. Furthermore, serology type of H. pylori with Vac A, Cag A relates to preterm birth even though high H. pylori prevalence rate.

    Full Text Available Objective Threatened miscarriage is a common complication in pregnancy that leads to adverse pregnancy outcomes such as preterm labor. This study aimed to compare the vaginal progesterone (Cyclogest versus 17-alpha-hydroxyprogesterone caproate (Proluton on preventing preterm labor in pregnant women with threatened abortion at less than 34 weeks’ gestational age. Materials and methods This balanced randomized, double-blind, single-center controlled clinical trial included 190 women with threatened abortion. They were then randomly allocated into Cyclogest (n=95 and 17-alpha-hydroxyprogesterone caproate (Proluton, n=95 groups. Interested outcome was preterm labor less than 34 weeks. The Pearson chi-square and Student’s t test were used to compare two groups. The data were analyzed by Stata software version 13. Results The risks of preterm labor less than 34 weeks in Proluton and Cyclogest groups were 8.6 and 6.52%, respectively. There was no significant difference for risk of preterm labor less than 34 weeks [relative ratio (RR: 1.31, 95% confidence interval (CI: 0.47- 3.66, P=0.59] between two groups. Conclusion Risk of preterm labor in the vaginal progesterone group and 17-alpha-hydroxyprogesterone caproate group in pregnant women with threatened abortion is the same (Registration Number: IRCT2014123120504N1.

    Full Text Available BACKGROUND: Spontaneous preterm birth (SPB, before 37 gestational weeks is a major cause of perinatal mortality and morbidity, but its pathogenesis remains unclear. Studies on SPB have been hampered by the limited availability of markers for SPB in predelivery clinical samples that can be easily compared with gestational age-matched normal controls. We hypothesize that SPB involves aberrant placental RNA expression, and that such RNA transcripts can be detected in predelivery maternal plasma samples, which can be compared with gestational age-matched controls. PRINCIPAL FINDINGS: Using gene expression microarray to profile essentially all human genes, we observed that 426 probe signals were changed by >2.9-fold in the SPB placentas, compared with the spontaneous term birth (STB placentas. Among the genes represented by those probes, we observed an over-representation of functions in RNA stabilization, extracellular matrix binding, and acute inflammatory response. Using RT-quantitative PCR, we observed differences in the RNA concentrations of certain genes only between the SPB and STB placentas, but not between the STB and term elective cesarean delivery placentas. Notably, 36 RNA transcripts were observed at placental microarray signals higher than a threshold, which indicated the possibility of their detection in maternal plasma. Among them, the IL1RL1 mRNA was tested in plasma samples taken from 37 women. It was detected in 6 of 10 (60% plasma samples collected during the presentation of preterm labor (≤32.9 weeks in women eventually giving SPB, but was detected in only 1 of 27 (4% samples collected during matched gestational weeks from women with no preterm labor (Fisher exact test, p = 0.00056. CONCLUSION: We have identified 36 SPB-associated RNA transcripts, which are possibly detectable in maternal plasma. We have illustrated that the IL1RL1 mRNA was more frequently detected in predelivery maternal plasma samples collected from women

    Incomplete spontaneous abortions are defined by the intrauterine retention of the products of conception after their incomplete or partial expulsion. This condition may be managed by expectant care, medical treatment or surgery. Vacuum aspiration is currently the standard surgical treatment in most centers. However, operative hysteroscopy has the advantage over vacuum aspiration of allowing the direct visualization of the retained conception product, facilitating its elective removal while limiting surgical complications. Inadequately powered retrospective studies reported subsequent fertility to be higher in patients treated by operative hysteroscopy than in those treated by vacuum aspiration. These data require confirmation in a randomized controlled trial comparing fertility rates between women undergoing hysteroscopy and those undergoing vacuum aspiration for incomplete spontaneous abortion. After providing written informed consent, 572 women with incomplete spontaneous abortion recruited from 15 centers across France will undergo randomization by a centralized computer system for treatment by either vacuum aspiration or operative hysteroscopy. Patients will not be informed of the type of treatment that they receive and will be cared for during their hospital stay in accordance with standard practices at each center. The patients will be monitored for pregnancy or adverse effects by a telephone conversation or questionnaire sent by e-mail or post over a period of two years. In cases of complications, failure of the intervention or diagnosis of uterine cavity disease, patient care will be left to the discretion of the medical center team. If our hypothesis is confirmed, this study will provide evidence that the use of operative hysteroscopy can increase the number of pregnancies continuing beyond 22 weeks of gestation in the two-year period following incomplete spontaneous abortion without increasing the incidence of morbidity and peri- and postoperative

    This study examined whether prenatal perceived stress levels during pregnancy were associated with preterm labor or preterm birth. Perceived stress levels were measured at 16 weeks' gestation or less and between 20 and 24 weeks' gestation in a sample of 1069 low-income pregnant women attending Temple University prenatal care clinics. Scores were averaged to create a single measure of prenatal stress. Preterm birth was defined as the occurrence of a spontaneous birth prior to 37 weeks' gestation. Preterm labor was defined as the occurrence of regular contractions between 20 and 37 weeks' gestation that were associated with changes in the cervix. Independent of potential confounding factors, prenatal perceived stress was not associated with preterm labor (odds ratio [OR], 1.10; 95% confidence interval [CI], 0.69-1.78; P = .66); however, prenatal stress trended toward an association with preterm birth (OR, 1.49; 95% CI, 1.00-2.23; P = .05). The strongest predictor of preterm labor was a history of preterm labor in a prior pregnancy. Women with a history of preterm labor were 2 times more likely to experience preterm labor in the current pregnancy than women who did not have a preterm labor history (OR, 2.16; 95% CI, 1.05-4.41; P = .04). Historical risk factors for preterm birth, such as African American race, a history of abortion, or a history of preterm birth, were not related to preterm labor. The strongest predictor of preterm birth was having a history of preterm birth in a prior pregnancy (OR, 2.55; 95% CI, 1.54-4.24; P stress levels may be a risk factor for preterm birth independent of preterm labor; however, prenatal stress was not associated with preterm labor. Risk factors for preterm labor may be different from those of preterm birth. © 2014 by the American College of Nurse-Midwives.

    This study provides evidence on the principal determinants of pregnancy and abortion in India using a large country-wide district-level data set (DLHS 2007). The paper provides an economic framework for the analysis of pregnancy and abortion. The study distinguishes between induced and spontaneous abortion and compares the effects of their determinants. The results show that there are wide differences between induced and spontaneous abortions in terms of the sign and magnitude of the estimated effects of several of their determinants, most notably wealth, the woman's age and her desire for children. The study makes a methodological contribution by proposing a trivariate probit estimation framework that recognizes the joint dependence of pregnancy and induced and spontaneous abortion, and provides evidence in support of this joint dependence. The study reports an inverted U-shaped effect of a woman's age on her pregnancy and both forms of abortion. The turning point in each case is quite robust to the estimation framework. A significant effect of contextual variables, at the village level, constructed from the individual responses, on a woman's pregnancy is found. The effects are weaker in the case of induced abortion, and insignificant in the case of spontaneous abortion. The results are shown to be fairly robust. This paper extends the literature on the relation between son preference and fertility by examining the link between mother's son preference and desire for more children with abortion rates.

    In women with preterm premature rupture of the membranes (PPROM), increased oxidative stress may accelerate premature cellular senescence, senescence-associated inflammation and proteolysis, which may predispose them to rupture. We demonstrate mechanistic differences between preterm birth (PTB) and PPROM by revealing differences in fetal membrane redox status, oxidative stress-induced damage, distinct signaling pathways and senescence activation. Oxidative stress-associated fetal membrane damage and cell cycle arrest determine adverse pregnancy outcomes, such as spontaneous PTB and PPROM. Fetal membranes and amniotic fluid samples were collected from women with PTB and PPROM. Molecular, biochemical and histologic markers were used to document differences in oxidative stress and antioxidant enzyme status, DNA damage, secondary signaling activation by Ras-GTPase and mitogen-activated protein kinases, and activation of senescence between membranes from the two groups. Oxidative stress was higher and antioxidant enzymes were lower in PPROM compared with PTB. PTB membranes had minimal DNA damage and showed activation of Ras-GTPase and ERK/JNK signaling pathway with minimal signs of senescence. PPROM had higher numbers of cells with DNA damage, prosenescence stress kinase (p38 MAPK) activation and signs of senescence. Samples were obtained retrospectively after delivery. The markers of senescence that we tested are specific but are not sufficient to confirm senescence as the pathology in PPROM. Oxidative stress-induced DNA damage and senescence are characteristics of fetal membranes from PPROM, compared with PTB with intact membranes. PTB and PPROM arise from distinct pathophysiologic pathways. Oxidative stress and oxidative stress-induced cellular damages are likely determinants of the mechanistic signaling pathways and phenotypic outcome.

    Currently, there is a growing concern regarding the safety of assisted reproductive technology (ART) due to increased risk of spontaneous abortion (SA) and imprinting disorders in ART-conceived offspring. Early investigations suggested that aberrant genetic imprinting may be related to pregnancy loss; however, few studies have used human tissue specimens. Here the DNA methylation patterns of 3 imprinted genes, including maternally inherited GRB10 and the paternally inherited IGF2 and PEG3 genes, were evaluated in human chorionic villus samples by pyrosequencing and bisulfite sequencing polymerase chain reaction. The samples were divided into 4 groups: (1) SA of natural conception (NC; n = 84), (2) induced abortion of NC (n = 94), (3) SA after ART (n = 73), and (4) fetal reduction after ART (n = 86). The methylation levels and the percentages of abnormal methylation of the IGF2, GRB10, and PEG3 genes between the ART group and the NC group showed no significant difference. Both IGF2 and GRB10 genes showed higher methylation levels in the SA group compared to the non-SA group. Additionally, determining the single-nucleotide polymorphisms of 4 loci, including IGF2 rs3741205, rs3741206, rs3741211, and GRB10 rs2237457, showed that the TC+CC genotype of IGF2 rs3741211 had a 1.91-fold increased risk of SA after ART. However, there was no association between the mutant genotype of IGF2 rs3741211 and the methylation levels of IGF2 and H19, and ART might not affect the distribution of the abovementioned genotypes. It provides support for the opinion that genetic imprinting defects may be associated with SA, which might not be due to ART treatments.

    Full Text Available Abstract Background Preterm birth (PTB, birth at <37 weeks of gestation, is a significant global public health problem. World-wide, about 15 million babies are born preterm each year resulting in more than a million deaths of children. Preterm neonates are more prone to problems and need intensive care hospitalization. Health issues may persist through early adulthood and even be carried on to the next generation. Majority (70 % of PTBs are spontaneous with about a half without any apparent cause and the other half associated with a number of risk factors. Genetic factors are one of the significant risks for PTB. The focus of this review is on single nucleotide gene polymorphisms (SNPs that are reported to be associated with PTB. Results A comprehensive evaluation of studies on SNPs known to confer potential risk of PTB was done by performing a targeted PubMed search for the years 2007–2015 and systematically reviewing all relevant studies. Evaluation of 92 studies identified 119 candidate genes with SNPs that had potential association with PTB. The genes were associated with functions of a wide spectrum of tissue and cell types such as endocrine, tissue remodeling, vascular, metabolic, and immune and inflammatory systems. Conclusions A number of potential functional candidate gene variants have been reported that predispose women for PTB. Understanding the complex genomic landscape of PTB needs high-throughput genome sequencing methods such as whole-exome sequencing and whole-genome sequencing approaches that will significantly enhance the understanding of PTB. Identification of high risk women, avoidance of possible risk factors, and provision of personalized health care are important to manage PTB.

    Full Text Available We examined the contribution of social disadvantage to the black-white disparity in preterm birth. Analyses included linked vital and hospital discharge records from 127,358 black and 615,721 white singleton California births from 2007-11. Odds ratios (OR were estimated by 4 logistic regression models for 2 outcomes: early (<32 wks and moderate (32-36 wks spontaneous preterm birth (ePTB, mPTB, stratified by 2 race-ethnicity groups (blacks and whites. We then conducted a potential impact analysis. The OR for less than high school education (vs. college degree was 1.8 (95% confidence interval 1.6, 2.1 for ePTB among whites but smaller for the other 3 outcome groups (ORs 1.3-1.4. For all 4 groups, higher census tract poverty was associated with increased odds (ORs 1.03-1.05 per 9% change in poverty. Associations were less noteworthy for the other variables (payer, and tract percent black and Gini index of income inequality. Setting 3 factors (education, poverty, payer to 'favorable' values was associated with lower predicted probability of ePTB (25% lower among blacks, 31% among whites but a 9% higher disparity, compared to probabilities based on observed values; for mPTB, respective percentages were 28% and 13% lower probability, and 17% lower disparity. Results suggest that social determinants contribute to preterm delivery and its disparities, and that future studies should focus on ePTB and more specific factors related to social circumstances.

    The purpose of this study was to determine whether quantification of cervicovaginal fluid fetal fibronectin (fFN) improves diagnostic accuracy of spontaneous preterm birth (sPTB) in symptomatic women. A prospective blinded predefined secondary analysis of a larger study of cervicovaginal fluid fFN concentration (nanograms per milliliter) in women symptomatic of preterm labor (n =300 women; 22-35 weeks' gestation) with a Hologic 10Q system (Hologic, Marlborough, MA). Clinicians were blinded to the result until after the delivery, but the qualitative Hologic TLI(IQ) fFN result was made available. The positive predictive value for sPTB (<34 weeks' gestation) increased from 19%, 32%, 61%, and 75% with increasing thresholds (10, 50, 200, and 500 ng/mL, respectively). Compared with <10 ng/mL fFN, the relative risk of delivery was 5.6 (95% confidence interval [CI], 1.05-29.57), 7.9 (95% CI, 1.38-45.0), 22.8 (95% CI, 3.84-135.5), and 51.3 (95% CI, 12.49-211.2; P < .01). Quantitative fFN provides thresholds (10 and 200 ng/mL) in addition to the qualitative method (50 ng/mL) to discriminate the risk of sPTB in symptomatic women. Copyright © 2013 Mosby, Inc.

    Understanding spontaneous preterm birth ([PTB] < 37 weeks) is difficult due to heterogeneities associated with multitudes of risk factors and pathophysiological pathways. Several biomarkers are routinely used clinically for predicting preterm labor; however, these factors are either nonspecific or detected too late. Systematic review of literature on PTB biomarkers in the last 40 years to map out the existing knowledge and gaps in understanding PTB biomarkers. Five electronic databases were searched for human studies on PTB biomarkers published in any language between 1965 and 2008. The phenotype of interest for final data extraction was exclusively spontaneous PTB with no rupture of membranes. Data extraction included (a) general characteristics of the study (clinical setting, period, and study design), (b) study/participant characteristics (inclusion and exclusion criteria, race/ethnicity, number of participants, gestational age at sampling, (c) characteristics of the biomarker (type, rationale for its selection, type of biological sample, and assay used, and (d) concentration of biomarkers in cases and controls. The search yielded 7255 citations and data were extracted from 217 articles which met our inclusion and exclusion criteria. A total of 116 different biomarkers were reported and these were assayed 578 times in the 217 included studies. Over two thirds of the 217 studies were performed on North American or European populations. No reliable biomarkers emerged as a risk predictor of PTB. Identifying similar studies on biomarkers for the prediction of PTB was a very challenging task due heterogeneities in study design, sampling issues (types, timing and processing), assay methods, and analyses. Major areas of concern identified in this review include poor phenotype definition, nonideal study designs and poor rationale for biomarker selection and assays and population stratification issues.

  5. [Abortion].

    Abortion is the interruption of a dynamic process in a final and irreversible form. The legalization of abortion is applied to human ontogenesis, that is, the development of the human being. However, the embryo that is growing in the uterus is not a human being because a human being is a complex organism with differentiated systems, its own identity and intrinsic autonomy in its process of development. There are basically four levels of the analysis of the problem of abortion: 1) fundamental emotional arguments; 2) profound ignorance of technical and scientific facts; 3) rational positions obfuscated by the dramatic intensity of everyday situations; and 4) the conjunction of deliberated position where culpability is avoided with solidarity for all subjects of the process with a socially oriented view. The phenomenon of abortion from an epidemiological point of view summons the facts with which it is associated: poverty, illiteracy, shortage or lack of community health resources, absence of centers for adolescents, degradation of the environment, and precariousness of employment.

    Full Text Available Background & Aim: Air pollution has been one of the threatening factors of human health during the last century. Particulate matters are the major air pollutants in urban areas. The aim of this study was to determine the effect of ambient particulate mattes on spontaneous abortion. Methods: This case-control study was conducted between June 2010 to February 2011 on 148 spontaneous abortion (case group and 148 pregnant women (control group in Tehran. From 22 regions of Tehran, 10 hospitals were randomly selected and samples were collected by simple random sampling from these hospitals. The mean of particulate matters was obtained from monitoring stations of Tehran Air Quality Control Company (TAQCC. Collected data was analyzed by the SPSS software using independent sample t-test, chi-square test, multiple and linear regression models. Results: Two groups in the study were matched in participants' age, husbands' age, age at first childbirth, educational level, family average income, previous type of delivery and the interval between deliveries, any previous abortion experience, body mass index, parity, duration of residence in Tehran and the amount of time spent at work and outside of home (P>0.05. On analyzing the collected data, it was revealed that the mean of ambient PM10 concentration in case group (94.4±39.22 micro gr/m3 was significantly higher than the control group (83.54±22.55 micro gr/m3 in T-test (P<0.001 and also the rate of abortion was higher in these areas (OR: 1.01, CI95%: 1.003-1.018. For assessing the relationship between gestational age and ambient PM10 concentration, linear regression method was used. Results indicated that there was a negative correlation between these variables. Conclusion: Findings of this study showed that there was a significant relationship between occurrence of spontaneous abortion and the ambient PM10 concentration.

    6 centers participated in a randomized comparison of the TCu 220C, Lippes Loop D, and Copper 7 intrauterine devices inserted immediately following spontaneous abortion. A total of 1060 insertions were performed with no perforations detected within the 1st 48 hours; only 9 subjects had complaints. At 390 and 750 days the continuation rates of all devices were equal. The expulsion rates were much lower than those with insertion immediately following the delivery of the placenta. There were no ectopic pregnancies reported and the incidence of pelvic inflammatory disease was low. It can be concluded that IUD insertion following spontaneous abortion in subjects with no signs of pelvic infection is safe and not associated with uterine perforation or a subsequent increased risk of pelvic inflammatory disease.

    A major cause of spontaneous abortions is chromosomal abnormality of foetal cells. We report the generation of an induced pluripotent stem cell line from the fibroblasts isolated from chorionic villi of an early spontaneously aborted foetus with Turner syndrome. The Turner syndrome villus induced pluripotent stem cell line is transgene free, retains the original XO karyotype, expresses pluripotency markers and undergoes trilineage differentiation. This pluripotent stem cell model of Turner syndrome should serve as a tool to study the developmental abnormalities of foetus and placenta that lead to early embryo lethality and profound symptoms like infertility in 45 XO survivors.

    ABSTRACT This study investigated whether lower vagal function in preterm infants is associated with increased fundamental frequency (F 0; frequency of vocal fold vibration) of their spontaneous cries. We assessed respiratory sinus arrhythmia (RSA) during quiet sleep as a measure of vagal function, and its relationship with the F 0 of spontaneous cries in healthy preterm and term infants at term‐equivalent age. The results showed that preterm infants have significantly lower RSA, and higher overall F 0 than term infants. Moreover, lower RSA was associated with higher overall F 0 in preterm infants, whereas higher RSA was positively associated with mean and maximum F 0, and a larger F 0 range in term infants. These results suggest that individual differences in vagal function may be associated with the F 0 of spontaneous cries via modulation of vocal fold tension in infants at an early developmental stage. © 2016 The Authors.

    The Health outcomes of an individual depend on his /her life position. The purpose of the present paper aimed to study spontaneous abortion (as a high risk factor among rural pregnant) due to their life status. The study was conducted among 40 young rural pregnant women, 12 to 20 years old by implementing a questionnaire during 2012 to 2013 in four villages in southeast of Iran. The women were exposed to high-risk factors such as shortage or lack of drinking water, high pressure electric power sources and chemicals released from burning gas both from cooking and cars as a fuel. The data were collected from the pregnant women coming into clinics. Results of the t-test and chi-square identified significant (P electric power source, pregnant women had 95% and 20% piped drinking water in villages of Iranshahr and Sarbaz, respectively. No houses in both villages were equipped with the gas fuel system. The findings suggest that a completely programmed surveillance program should be undertaken to implemented remedy in environmental shortages for pregnant rural women.

    Full Text Available BACKGROUND: Studies on the risk of chromosomal abnormalities in early spontaneous abortion after assisted reproductive technology (ART are relatively controversial and insufficient. Thus, to obtain a more precise evaluation of the risk of embryonic chromosomal abnormalities in first-trimester miscarriage after ART, we performed a meta-analysis of all available case-control studies relating to the cytogenetic analysis of chromosomal abnormalities in first-trimester miscarriage after ART. METHODS: Literature search in the electronic databases MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL based on the established strategy. Meta-regression, subgroup analysis, and Galbraith plots were conducted to explore the sources of heterogeneity. RESULTS: A total of 15 studies with 1,896 cases and 1,186 controls relevant to the risk of chromosomal abnormalities in first- trimester miscarriage after ART, and 8 studies with 601 cases and 602 controls evaluating frequency of chromosome anomaly for maternal age≥35 versus <35 were eligible for the meta-analysis. No statistical difference was found in risk of chromosomally abnormal miscarriage compared to natural conception and the different types of ART utilized, whereas the risk of fetal aneuploidy significantly increased with maternal age≥35 (OR 2.88, 95% CI: 1.74-4.77. CONCLUSIONS: ART treatment does not present an increased risk for chromosomal abnormalities occurring in a first trimester miscarriage, but incidence of fetal aneuploidy could increase significantly with advancing maternal age.

    Background: Recurrent Spontaneous Abortion (RSA) is caused by multiple genetic and non-genetic factors. Around 50% of the RSA cases have no known etiology and are considered as Unexplained RSA (URSA). Estrogens, via binding to their receptors, play an important role in female reproduction. This study aimed to investigate whether single nucleotide polymorphisms (SNPs; +1082G/A, +1730G/A and rs1256030 C/T) in the estrogen receptor beta (ESR2) gene are associated with susceptibility to URSA in a population of Iranian women. Methods: In this case-control study, the study groups consisted of 240 subjects with a history of URSA and 102 fertile women as controls. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) were measured on day 2–3 of menstrual cycle. Two functional SNPs, +1082G/A (a silent mutation in exon 5) and +1730G/A (3′ untranslated region of the exon 8), and one intron, rs1256030C/T, in the ESR2 gene were genotyped, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Results: Serum levels of LH were significantly increased in URSA women. No significant differences in distribution of +1082G/A, +1730G/A and rs1256030C/T between URSA and control groups were observed. Conclusion: Our findings suggest that the studied SNPs on ESR2 gene may not be associated with URSA. PMID:28706612

    Full Text Available Background: Immunotherapy with paternal lymphocytes plays an important role in preventing recurrent spontaneous abortion (RSA and is an effective treatment for it. This kind of treatment is performed as an immunotherapy method in several centers in the world. It attributes to the production of anti-paternal cytotoxic antibodies (APCAs in women with RSA. Production of APCA after lymphocyte immunotherapy (LIT in RSA patients gives them a better chance for successful pregnancy. Regarding the important effect of trace elements on the function of the immune system, we tried to investigate the correlation between serum zinc level and the success of LIT in RSA. Materials and Methods: Serum zinc concentration was determined in two groups of RSA patients using atomic absorption spectrophotometer systems. Group (a that responded to the paternal lymphocytes and their cross-match test was positive, and group (b that had no response to the paternal lymphocytes immunizations and their cross-match test was negative. Results: Serum zinc levels in group (a patients were 74.98 ± 11.88 μg/dl, which was significantly higher than those in group (b with the zinc concentration of 64.22 ± 9.22 μg/dl. Conclusions: Zinc deficiency may be one of the substantial causes of negative results for LIT in RSA patients. Therefore, compensation of zinc defect before LIT can be a promising approach to improve the immune response in patients.

    Evaluating and understanding the risk and safety of using medications for autoimmune disease in a woman during her pregnancy will help both clinicians and pregnant women to make better treatment decisions. However, utilizing spontaneous abortion (SAB) data collected in observational studies of pregnancy to derive valid inference poses two major challenges. First, the data from the observational cohort are not random samples of the target population due to the sampling mechanism. Pregnant women with early SAB are more likely to be excluded from the cohort, and there may be substantial differences between the observed SAB time and those in the target population. Second, the observed data are heterogeneous and contain a "cured" proportion. In this article, we consider semiparametric models to simultaneously estimate the probability of being cured and the distribution of time to SAB for the uncured subgroup. To derive the maximum likelihood estimators, we appropriately adjust the sampling bias in the likelihood function and develop an expectation-maximization algorithm to overcome the computational challenge. We apply the empirical process theory to prove the consistency and asymptotic normality of the estimators. We examine the finite sample performance of the proposed estimators in simulation studies and illustrate the proposed method through an application to SAB data from pregnant women. © The Author 2017.

    The aim of this study was to evaluate whether the presence of history of biochemical pregnancy (BP) was associated with clinical characteristics and the subsequent pregnancy outcome among women with recurrent spontaneous abortion (RSA). One-hundred and seventy-five RSA women with two or more clinical pregnancy losses were enrolled. The clinical characteristics were compared between 164 women with history of 0-1 BP (Group A) and 11 women with two or more BP (Group B). The frequency of previous pregnancy loss and history of in vitro fertilization and embryo transfer in Group B was higher than that in Group A; while frequency of secondary RSA in Group B was lower than Group A. The subsequent pregnancy outcome was assessed prospectively; and live-birth rate in Group A (72.9%) was higher (p < 0.05) than that in Group B (41.7%). The incidence of reproductive failure (58.3%, p < 0.05) and spontaneous abortion with normal chromosome (25.0%, p = 0.050) in Group B was higher than those (27.1 and 5.9%, respectively) in Group A. RSA women with two or more BP had higher risk of reproductive failure and spontaneous abortion with normal chromosome together with lower chance of live-birth. The results of the present study involve important information and are helpful for clinical practitioners.

    To develop a model for prediction of spontaneous delivery before 34 weeks based on maternal factors, placental perfusion and function at 11-13 weeks' gestation. Two groups of studies: first, screening study of maternal characteristics, serum pregnancy-associated plasma protein-A (PAPP-A), free β-human chorionic gonadotrophin (β-hCG) and uterine artery pulsatility index (PI). Second, case-control studies of maternal serum or plasma concentration of placental growth factor (PlGF), placental protein 13 (PP13), a disintegrin and metalloprotease 12 (ADAM12), inhibin-A and activin-A. Regression analysis was used to develop a model for the prediction of spontaneous early delivery. Spontaneous early delivery occurred in 365 (1.1%) of the 34 025 pregnancies. A model based on maternal factors could detect 38.2% of the preterm deliveries in women with previous pregnancies at or beyond 16 weeks and 18.4% in those without, at a false positive rate (FPR) of 10%. In the preterm delivery group, compared with unaffected pregnancies there were no significant differences in the markers of placental perfusion or function, except for PAPP-A which was reduced. Patient-specific risk of preterm delivery is provided by maternal factors and obstetric history. Placental perfusion and function at 11-13 weeks are not altered in pregnancies resulting in spontaneous early delivery. Copyright © 2011 John Wiley & Sons, Ltd.

    Recently, an association between human papillomavirus infection and both spontaneous abortion and spontaneous preterm delivery was suggested. However, the reported human papillomavirus prevalence in pregnant women varies considerably and reliable conclusions are difficult. We aimed to investigate human papillomavirus infection in placental tissue of a Danish study cohort. Furthermore, we studied the cellular localization of human papillomavirus. In this prospective case-control study, placental tissue was analyzed for human papillomavirus infection by nested PCR in the following four study groups: full-term delivery (n = 103), spontaneous preterm delivery (n = 69), elective abortion (n = 54), and spontaneous abortion (n = 44). Moreover, human papillomavirus cellular target was identified using in situ hybridization. Human papillomavirus prevalence in placental tissue was 8.7% in full-term deliveries, 8.8% in spontaneous preterm deliveries, 10.9% in spontaneous abortions, and 20.4% in elective abortions. Twelve different human papillomavirus types were detected, and placental human papillomavirus infection was associated to a disease history of cervical cancer. Human papillomavirus DNA was identified in trophoblast cells, cells of the placental villi mesenchyme including Hofbauer cells, and in parts of the encasing endometrium. Placental human papillomavirus infections are not likely to constitute a risk factor for spontaneous preterm labor or spontaneous abortions in the Danish population, although an effect of human papillomavirus DNA in placental cells cannot be excluded. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    . Conclusão: para uma investigação completa dos fatores associados ao aborto espontâneo recorrente faz-se necessária a inclusão do fator aloimune, sem a qual a maior parte dos casos não terá etiologia esclarecida.Purpose: to identify recurrent spontaneous abortion- associated factors. Subjects: one hundred seventy-five outpatients were investigated from March 1993 to March 1997 at the "Ambulatório de Aborto Recorrente CAISM/UNICAMP". All of them had had three or more consecutive spontaneous abortions and/or two abortions and were 35 years or more old. Methods: the investigation protocol included: couple's karyotype; hysterosalpingography, serial plasma progesterone levels and/or endometrial biopsy; toxoplasmosis, listeriosis, brucelosis, lues and cytomegalovirus serum tests; Chlamydia trachomatis and Mycoplasma hominis cultures of cervical discharge; TSH and thyroid hormone levels; fasting glucose; autoantibody panel, anti-HLA antibody search by microlymphocytotoxicity crossmatch and one-way mixed lymphocyte culture with inhibitor factor detection. Husband's evaluation included: physical evaluation, lues, Chagas' disease, B and C hepatitis and AIDS serum tests, microlymphocytotoxicity crossmatch and one-way mixed lymphocyte culture with inhibitor factor detection. Results: alloimmune etiology was the most frequently found factor (86.3% of studied patients, represented by negative crossmatch and one-way mixed lymphocyte culture with inhibitor factor below 50%. The second most frequently found factor was cervical incompetence (22.8%, followed by hormonal factor (21.2%, mainly represented by luteal insufficiency. Some patients were found to have more than one etiologic factor. Conclusion: the investigation of recurrent spontaneous abortion-associated factors must include alloimmune etiology. Most cases will remain unexplained without this investigation.

    Full Text Available Background: Congenital toxoplasmosis is an important cause of spontaneous abortion worldwide. However, there is limited information on detection and genotypic characterization of Toxoplasma gondii (T. gondii in women with recurrent spontaneous abortion (RSA. The aim of this study is the molecular detection and genotypic characterization of T. gondii in formalin-fixed, paraffin-embedded fetoplacental tissues (FFPTs of women with RSA that have referred to the Avicenna Research Institute in Tehran, Iran. Materials and Methods: This experimental research was undertaken on 210 FFPTs of women with RSA. The information of the patients was collected from the archives of Avicenna Research Institute in Tehran, Iran. After DNA extraction, the presence of T. gondii was examined by nested polymerase chain reaction targeting the GRA6 gene. Genotyping was performed on positive samples using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP that targeted the GRA6 and SAG3 genes. Sequencing was conducted on two GRA6 positive samples. Results: T. gondii DNA was detected in 3.8% (8/210 of the samples. Genotyping showed that all positive samples belonged to type III of the T. gondii genotype. Sequencing two genomic DNAs of the GRA6 gene revealed 99% similarity with each other and 99-100% similarity with T. gondii sequences deposited in GenBank. There were six patients with histories of more than three abortions; one patient had a healthy girl and another patient had two previous abortions. Abortions occurred in the first trimester of pregnancy in seven patients and in the second trimester of pregnancy in one patient. Conclusion: The results of this study have indicated that genotype III is the predominant type of T. gondii in women with RSA in Tehran, Iran. Also, our findings suggest that toxoplasmosis may play a role in the pathogenesis of RSA. However, further studies are needed to elucidate a clear relationship between T. gondii

    The pathophysiology of spontaneous abortion is complex and may involve the interaction of genetic and environmental factors. We evaluated the predictors of spontaneous abortion in Brazilian pregnant women. The effects of age, gestational age, body mass index (BMI), cigarette smoking, alcohol ingestion, use of multivitamins and concentrations of vitamins (folate, cobalamin and vitamin B6) and vitamin-dependent metabolites were analyzed. Study population included 100 healthy women that attended pre-natal care in 2 health centers of Sao Paulo, Brazil, and in whom pregnancy outcome was known. Folate and cobalamin status was measured in blood specimens collected between 4 and 16 weeks. The genotypes for 8 gene polymorphisms were evaluated by PCR-RFLP. Eighty-eight women had normal pregnancy outcome (Group 1), while 12 experienced a miscarriage after blood collection (Group 2). Increased methylmalonic acid (MMA) concentrations were found in Group 2 (median [25th-75th percentile]=274 [149-425] nmol/l) relative to Group 1 (138 [98-185]) (PMMA, cystathionine, body mass index (BMI), cigarette smoking, alcohol ingestion and use of multivitamins the risk of abortion was significantly associated with MMA (OR [95% CI]=3.80 [1.36, 10.62] per quartile increase in MMA), BMI (OR [95% CI]=5.49 [1.29, 23.39] per quartile) and gestational age (OR [95% CI]=0.10 [0.01, 0.77] per increase of interval in gestational age). Increased serum MMA and BMI concentrations are associated with spontaneous abortion in Brazilian women. Copyright 2009 Elsevier B.V. All rights reserved.

    Living in areas with high air pollution may have adverse effects on human health. There are few studies about the association between breathing polluted air and adverse pregnancy outcomes in the Middle East. The aim of this study was to determine the relationship between air pollution and spontaneous abortion, premature birth, and stillbirth in Ahvaz. A time-series study was conducted. Data about spontaneous abortion, premature deliveries, and stillbirth was collected from Ahvaz Imam Khomeini Hospital. Air pollution data including NO, CO, NO 2 , PM 10 , SO 2 , O 3 , and climate data were, respectively, collected from the Environmental Protection Agency and the Khuzestan Province Meteorology Office from March 2008 until March 2015. The relationship between air pollutants with the number of abortions, premature births, and stillbirths was found using a quasi-Poisson distributed lag model, adjusted by trend, seasonality, temperature, relative humidity, weekdays, and holidays. The average daily dust in Ahvaz on 7.2% days of the year was higher than 500 μg/m 3 (very dangerous). Findings from this study indicate a significant association between each 10-unit increase in SO 2 and spontaneous abortion in lag 0 and 9 days. There was a significant relation between each 10-unit increase in NO 2 and CO, and premature birth in lag 0. Also, we found a significant association between each 10-unit increase in CO and premature delivery in lag 1; PM 10 and premature delivery in lags 10, 11, and 12; and NO and premature delivery in lags 3, 4, 10, 11, 12, and 13 (p value polluted air during pregnancy may increase adverse pregnancy outcomes and stillbirth. Pregnant women should avoid polluted air.

     The objective of this study was to evaluate the effect of prior term birth on recurrent spontaneous preterm birth (sPTB) risk.  Retrospective cohort study of 211 women with prior sPTB, comparing women with and without prior term births. The primary outcome was recurrent sPTB term births (28.9 vs. 37.7%, p  = 0.2). Among women with prior second-trimester loss (16-23 6/7 weeks), those with a term birth had a decreased sPTB rate (15.4 vs. 43.2%, p  = 0.02), which persisted after adjusting for age and 17-α hydroxyprogesterone caproate use. For women with prior sPTB ≥24 weeks, there was no difference in sPTB with and without prior term births (29.5 vs. 26.6%, p  = 0.7). A term birth as the most recent delivery lowered, but did not eliminate, the sPTB risk (19.1 vs. 36.4%, p  = 0.1).  Prior term birth lowers the risk of recurrent sPTB for women with prior second-trimester loss, but not for women with prior sPTB ≥24 weeks. Women with prior preterm and term births should be counseled accordingly and all sPTB prevention strategies should be recommended.

    Full Text Available Abstract Background Research on the potentially adverse effects of occupational pesticide exposure on risk of spontaneous abortion (SAB is limited, particularly among female agricultural workers residing in developing countries. Methods Reproductive histories were obtained from 217 Ecuadorian mothers participating in a study focusing on occupational pesticide exposure and children's neurobehavioral development. Only women with 2+ pregnancies were included in this study (n = 153. Gravidity, parity and frequency of SAB were compared between women with and without a history of working in the cut-flower industry in the previous 6 years. Logistic regression analysis was conducted to assess the relation between SAB and employment in the flower industry adjusting for maternal age. Results In comparison to women not working in the flower industry, women working in the flower industry were significantly younger (27 versus 32 years and of lower gravidity (3.3 versus 4.5 and reported more pregnancy losses. A 2.6 (95% CI: 1.03-6.7 fold increase in the odds of pregnancy loss among exposed women was observed after adjusting for age. Odds of reporting an SAB increased with duration of flower employment, increasing to 3.4 (95% CI: 1.3, 8.8 among women working 4 to 6 years in the flower industry compared to women who did not work in the flower industry. Conclusion This exploratory analysis suggests a potential adverse association between employment in the cut-flower industry and SAB. Study limitations include the absence of a temporal relation between exposure and SAB, no quantification of specific pesticides, and residual confounding such as physical stressors (i.e., standing. Considering that approximately half of the Ecuadorian flower laborers are women, our results emphasize the need for an evaluating the reproductive health effects of employment in the flower industry on reproductive health in this population.

    Spontaneous abortion (SA) is a common complication of pregnancy. Presence of lupus anticoagulant (LA), one of the antiphospholipid antibodies, has been associated with SA in many studies, especially in Caucasians. This study was carried out to determine the prevalence of LA in women with SA in ABUTH, Zaria. A cohort of 100 consecutive women presenting with SA with no history of thrombotic episodes were enrolled into the study. Prothrombin time (PT), kaolin clotting time (KCT), and activated partial thromboplastin time (APTT) were conducted on samples of all the participants. Eight patients had prolonged APTT, and after a 50:50 mixture of their plasma with pooled control plasma, four (50%) had uncorrected APTT. Staclot® (a hexagonal-phase phospholipid) test and calculated Rosner index for prolonged KCT were used for the confirmation of LA in samples with uncorrected APTT after mixing studies. We analyzed 100 women with one or more SA with a mean age of 31.0 ± 3.8 years. Nearly 4% and 3% of the participants were LA positive with Staclot® and KCT tests, respectively. Patients with LA were more likely to have had a past history of preeclampsia/eclampsia, small for gestational age deliveries, and previous SA (prevalence odds ratio [95% confidence interval]) of 1.9 (0.2, 20.1), 3.2 (0.3, 34.3), and 1.4 (0.1-13.6), respectively. The PT, APTT, and KCT were significantly prolonged in patients with LA (P ≤ 0.001 for each, respectively). LA may be one of the causes of SA and other adverse pregnancy outcomes such as preeclampsia/eclampsia and small for date deliveries. It is recommended that patients with prolonged APTT, uncorrected with 50:50 mixing study with pooled control plasma, should be evaluated further for LA.

    Full Text Available BACKGROUND: We attempt to ascertain if the 3 linked single nucleotide polymorphisms (SNPs of the Progesterone Receptor (PR gene (exon 1: G 1031 C; S344T, exon 4: G 1978 T; L660V and exon 5: C 2310 T; H770H and the PROGINS insertion in the intron G, between exons 7 and 8, are associated with Recurrent Spontaneous Abortion (RSA in the Indian population. METHODOLOGY/PRINCIPAL FINDINGS: A total of 143 women with RSA and 150 controls were sequenced for all the 8 exons looking for the above 3 linked SNPs of the PR gene earlier implicated in the RSA, as well as for any new SNPs that may be possibly found in the Indian population. PROGINS insertion was screened by electrophoresis. We did not find any new mutations, not observed earlier, in our population. Further, we did not find significant role of the *2 allele (representing the mutant allele at the three SNP loci or the T2 allele (PROGINS insertion in the manifestation of RSA. We also did not find an LD pattern between each of the 3 SNPs and the PROGINS insertion. CONCLUSIONS/SIGNIFICANCE: The results suggest that the PR gene mutations may not play any exclusive role in the manifestation of RSA, and instead, given significantly higher frequency of the *2 allele among the normal women, we surmise if it does not really confer a protective role among the Indian populations, albeit further studies are required in the heterogeneous populations of this region before making any conclusive statement.

Materials and Methods: Retrospective analysis of cytogenetics data obtained by culturing/harvesting products of the conception material at our center from 2006 to 2009 was performed. The abnormal cytogenetic results, maternal age, gestational age, and previous pregnancy history were recorded and compared. Results: Double and multiple aneuploidies are rare, however, a high percentage of double (4.6% and multiple (0.4% chromosomal aneuploidies were observed in our study of 1502 cases of SAB. Of 1502 cases of SAB evaluated, 70 cases (4.6% showed double aneuploidy, whereas 6 cases (0.4% had multiple aneuploidies. The chromosomes most frequently involved in double aneuploidy in the decreasing order were 21, 16, ± X, 22, 18, 13, and 15. The most frequent chromosome combinations observed were: Loss of X/21 (8.5%, 21/22 (4.4%, 16/21 (4.4%, and 7/16 (4.4%. The chromosome combinations in multiple aneuploidy included trisomy of chromosomes X/5/8, 8/20/22, 16/20/22, 14/21/22, and loss of X with 21/21 and 7/21. These abnormalities were significantly observed in women between the age group 40-44 years (59.2%. A high success rate (94% of obtaining metaphase cells was observed in this study mainly due to the use of direct and long-term cultures. Conclusions: We observed a high percentage of double (4.6% and multiple (0.4% aneuploidies, frequently involving the acrocentic chromosomes 13, 15, 21, and 22 and nonacrocentric chromosomes X, 16, and 18.

    Full Text Available Abstract Background Blood lead has been associated with an elevated risk of miscarriage. The plasmatic fraction of lead represents the toxicologically active fraction of lead. Women with a tendency to have a higher plasma/whole blood Pb ratio could tend towards an elevated risk of miscarriage due to a higher plasma Pb for a given whole blood Pb and would consequently have a history of spontaneous abortion. Methods We studied 207 pregnant Mexico City residents during the 1st trimester of pregnancy, originally recruited for two cohorts between 1997 and 2004. Criteria for inclusion in this study were having had at least one previous pregnancy, and having valid plasma and blood Pb measurements. Pb was measured in whole blood and plasma by inductively coupled plasma mass spectrometry using ultra-clean techniques. History of miscarriage in previous pregnancies was obtained by interview. The incidence rate of spontaneous abortion was defined as the proportion of previous pregnancies that resulted in miscarriage. Data were analyzed by means of Poisson regression models featuring the incidence rate of spontaneous abortion as the outcome and continuous or categorized plasma/blood Pb ratios as predictor variables. All models were adjusted for age and schooling. Additionally, logistic regression models featuring inclusion in the study sample as the outcome were fitted to assess potential selection bias. Results The mean number of miscarriages was 0.42 (range 0 to 4; mean Pb concentrations were 62.4 and 0.14 μg/L in whole blood and plasma respectively. Mean plasma/blood Pb ratio was 0.22%. We estimated that a 0.1% increment in the plasma/blood Pb ratio lead was associated to a 12% greater incidence of spontaneous abortion (p = 0.02. Women in the upper tertile of the plasma/blood Pb ratio had twice the incidence rate of those in the lower tertile (p = 0.02. Conditional on recruitment cohort, inclusion in the study sample was unrelated to observable

    The individual motor elements presumed to be essential for motor development were determined from spontaneous movements involving the entire body of normal term and preterm infants. Then, diagnostic items for motor abnormality in infants with periventricular leukomalacia (PVL) were investigated. Video recordings of 24 healthy term infants, 21 normal preterm infants (8 males, 13 females; median gestational age 30 weeks; median birth weight 1216g) and 14 preterm infants with PVL (6 males, 8 females; median gestational age 30 weeks; median birth weight 1360g) were analyzed. In healthy term infants, predominant shoulder rotation was noticed until 1 month of age. After 2 months of age, isolated movements of the shoulder, elbow, hip, knee, and ankle frequently emerged. In preterm infants with PVL at the corrected age of 2 months, startle response and predominant shoulder rotation were more frequently seen and isolated neck, shoulder, elbow, hip, knee, and ankle movements were less frequently seen than in the normal preterm infants (Fisher's exact test, p<0.025). At 2 months of age, isolated movements evolve, and their failure to occur is suggested to be a useful sign for the diagnosis of cerebral motor disorders.

    Although it is well known that post-abortion contraceptive use is high when family planning services are provided following spontaneous or induced abortions, this relationship remains unclear in Brazil and similar settings with restrictive abortion laws. Our study aims to assess whether contraceptive use is associated with access to family planning services in the six-month period post-abortion, in a setting where laws towards abortion are highly restrictive. This prospective cohort study recruited 147 women hospitalized for emergency treatment following spontaneous or induced abortion in Brazil. These women were then followed up for six months (761 observations). Women responded to monthly telephone interviews about contraceptive use and the utilization of family planning services (measured by the utilization of medical consultation and receipt of contraceptive counseling). Generalized Estimating Equations were used to analyze the effect of family planning services and other covariates on contraceptive use over the six-month period post-abortion. Women who reported utilization of both medical consultation and contraceptive counseling in the same month had higher odds of reporting contraceptive use during the six-month period post-abortion, when compared with those who did not use these family planning services [adjusted aOR = 1.93, 95 % Confidence Interval: 1.13-3.30]. Accessing either service alone did not contribute to contraceptive use. Age (25-34 vs. 15-24 years) was also statistically associated with contraceptive use. Pregnancy planning status, desire to have more children and education did not contribute to contraceptive use. In restrictive abortion settings, family planning services offered in the six-month post-abortion period contribute to contraceptive use, if not restricted to simple counseling. Medical consultation, in the absence of contraceptive counseling, makes no difference. Immediate initiation of a contraceptive that suits women's pregnancy

    To determine the measures to prevent spontaneous preterm birth (excluding preterm premature rupture of membranes)and its consequences. The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. In France, premature birth concerns 60,000 neonates every year (7.4 %), half of them are delivered after spontaneous onset of labor. Among preventable risk factors of spontaneous prematurity, only cessation of smoking is associated to a decrease of prematurity (level of evidence [LE] 1). This is therefore recommended (grade A). Routine screening and treatment of vaginal bacteriosis in general population is not recommended (grade A). Asymptomatic women with single pregnancy without history of preterm delivery and a short cervix between 16 and 24 weeks is the only population in which vaginal progesterone is recommended (grade B). A history-indicated cerclage is not recommended in case of only past history of conisation (grade C), uterine malformation (Professional consensus), isolated history of pretem delivery (grade B) or twin pregnancies in primary (grade B) or secondary (grade C) prevention of preterm birth. A history-indicated cerclage is recommended for single pregnancy with a history of at least 3 late miscarriages or preterm deliveries (grade A).). In case of past history of a single pregnancy delivery before 34 weeks gestation (WG), ultrasound cervical length screening is recommended between 16 and 22 WG in order to propose a cerclage in case of lengthpremature rupture of membranes. Maintenance tocolysis is not recomended (grade B). Antenatal corticosteroid administration is recommended to every woman at risk of preterm delivery before 34 weeks of gestation (grade A). After 34 weeks, evidences are not consistent enough to recommend systematic antenatal corticosteroid treatment (grade B), however, a course might be indicated in the clinical situations associated with the

    Providing less invasive surfactant administration (LISA) to spontaneously breathing preterm infants has been reported to reduce mechanical ventilation and bronchopulmonary dysplasia (BPD) in randomised controlled trials. This large cohort study compared these outcome measures between LISA-treated infants and controls. Infants receiving LISA, who were born before 32 gestational weeks and enrolled in the German Neonatal Network, were matched to control infants by gestational age, umbilical cord pH, Apgar-score at 5 min, small for gestational age status, antenatal treatment with steroids, gender and highest supplemental oxygen during the first 12 h of life. Outcome data were compared with chi-square and Mann-Whitney U-tests and adjusted for multiple comparisons. Between 2009 and 2012, 1103 infants were treated with LISA at 37 centres. LISA infants had lower rates of mechanical ventilation (41% versus 62%, p mechanical ventilation and BPD. Additional large-scale randomised controlled trials are needed to assess the possible long-term benefits of LISA. ©2014 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    This review aimed to identify, synthesize, and analyze the findings of studies on proteomic biomarkers for spontaneous preterm birth (PTB). Three electronic databases (Medline, Embase, and Scopus) were searched for studies in any language reporting the use of proteomic biomarkers for PTB published between January 1994 and December 2012. Retrieved citations were screened, and relevant studies were selected for full-text reading, in triplicate. The search yielded 529 citations, 51 were selected for full-text reading and 8 studies were included in the review. A total of 64 dysregulated proteins were reported. Only 14-3-3 protein sigma, annexin A5, protein S100-A8, protein S100-A12, and inter-α-trypsin inhibitor heavy chain H4 were reported in more than 1 study, but results could not be combined due to heterogeneity in type of sample and analytical platform. In conclusion, according to the existing literature, there are no specific proteomic biomarkers capable of accurately predicting PTB.

    Full Text Available Background: Recurrent spontaneous abortion is one of the diseases that can lead to physical, psychological, and, economical problems for both individuals and society. Recently a few numbers of genetic polymorphisms in kinase insert domain-containing receptor (KDR gene are examined that can endanger the life of the fetus in pregnant women. Objective: The risk of KDR gene polymorphisms was investigated in Iranian women with idiopathic recurrent spontaneous abortion (RSA. Materials and Methods: A case controlled study was performed. One hundred idiopathic recurrent spontaneous abortion patients with at least two consecutive pregnancy losses before 20 weeks of gestational age with normal karyotypes were included in the study. Also, 100 healthy women with at least one natural pregnancy were studied as control group. Two functional SNPs located in KDR gene; rs1870377 (Q472H, and rs2305948 (V297I as well as one tag SNP in the intron region (rs6838752 were genotyped by using PCR based restriction fragment length polymorphism (PCR-RFLP technique. Haplotype frequency was determined for these three SNPs’ genotypes. Analysis of genetic STRUCTURE and K means clustering were performed to study genetic variation. Results: Functional SNP (rs1870377 was highly linked to tag SNP (rs6838752 (D´ value=0. 214; χ2 = 16.44, p<0. 001. K means clustering showed that k = 8 as the best fit for the optimal number of genetic subgroups in our studied materials. This result was in agreement with Neighbor Joining cluster analysis. Conclusion: In our study, the allele and genotype frequencies were not associated with RSA between patient and control individuals. Inconsistent results in different populations with different allele frequencies among RSA patients and controls may be due to ethnic variation and used sample size.

    Spontaneous abortion (SA) is one of the prevalent negative reproductive outcomes among women around the world, which is a great challenge faced by maternal health promotion. The present study is aimed to explore the association between SA and socioeconomic status (SES) and provides reference for policy makers to improve strategies on maternal health promotion. A cross-sectional analysis was conducted with baseline data from a large-scale population-based cohort study of 0.5 million people from 10 geographically diverse areas of China recruited from 2004 to 2008. The study collected data from 84,531 women aged 35-45 years old in the baseline survey of China Kadoorie Biobank. Participants were interviewed using a standardized questionnaire, and information on demographic-socioeconomic as well as reproductive health status was collected. Odds ratios (OR) with 95% CI, estimated by a multistep logistic regression, were used to approximate the associations between SA occurrence and characteristics of SES. A stratification analysis was also applied to find out how SES influenced women's reproductive health outcomes differently between rural and urban areas. The model was adjusted for age at study date, tea consumption, alcohol consumption, cigarette smoking, and number of induced abortion. The risk of SA in rural was 1.68 times greater than in urban (AOR = 1.68, 95%CI: 1.54-1.84). Women with high income had a decreased risk of SA when compared with that of women with low income (AOR = 0.90, 95%CI: 0.84-0.97). Compared with women in low educational attainment, women in higher educational attainment had a lower prevalence of SA (AOR = 0.90, 95%CI: 0.82-0.98). The risk of SA only reduced in factory worker (AOR = 0.59, 95%CI: 0.53-0.66) and professional worker (AOR = 0.75, 95%CI: 0.66-0.84) compared with agriculture and related workers. After stratifying by rural/urban, the association between income and SA in urban (AOR = 0.88, 95%CI: 0.78-0.99) was

    In preterm infants with respiratory distress syndrome, surfactant administration followed by immediate extubation to spontaneous breathing with nasal continuous positive airway pressure reduces the need for mechanical ventilation. With this treatment approach, repeated doses of surfactant are rarely indicated. We used a rabbit model to test the hypothesis that exogenous surfactant therapy followed by spontaneous breathing results in a more sustained initial treatment response compared with treatment followed by mechanical ventilation. Preterm rabbits (gestational age 28.5 d) were treated with pharyngeal deposition of 200 mg/kg radiolabeled surfactant (14C-Curosurf) and randomized to 4 h of spontaneous breathing or mechanical ventilation or to a control group, killed immediately after surfactant administration. With pharyngeal deposition, 46 +/- 10% (mean +/- SEM) of the administered surfactant reached the lungs. The dynamic lung-thorax compliance was higher in spontaneously breathing compared with mechanically ventilated animals (median, 9.9 and 0.75 ml x cm H2O(-1) x kg(-1), respectively; p mechanically ventilated animals (p mechanically ventilated animals. We conclude that the initial lung tissue association of exogenous surfactant is impaired by mechanical ventilation. This is associated with a reduction of dynamic compliance and evidence of increased surfactant inactivation.

    Human leukocyte antigens (HLA)-G and HLA-E are non-classical HLA class I antigens expressed on extravillous cytotrophoblast that invades decidua in the uterus during pregnancy and are postulated to help in maternal immunotolerance of the fetus. Published results on the relation between HLA-G and HLA-E polymorphisms and unexplained recurrent spontaneous abortion (RSA) are, however, controversial. This study was initiated in order to investigate whether HLA-G (G*0103, G*0104 and G0105N) and HLA...

    To investigate the association between the genetic polymorphism of 2',5'-oligoadenylate synthetase 1 (OAS1) and susceptibility to spontaneous preterm birth (SPTB) and preterm premature rupture of membranes (PPROM). The case-control study consisted of 599 preterm infants including 171 cases of PPROM, and 673 full-term infants without maternal histories of SPTB and PPROM as controls. The single nucleotide polymorphism (SNP) at OAS1 intron 5, rs10774671, was analyzed by polymerase chain reaction-restriction fragment length polymorphism. No significant differences were observed between the case and control groups in the frequencies of genotypes (AA, GA, and GG) and alleles (A and G) of OAS1 rs10774671. When the case group was divided into two subgroups with or without PPROM, no significant differences in the genotype and allele frequencies were found between each subgroup and the control group. When the case group was divided into three subgroups with different gestational ages at SPTB, no significant differences in the genotype and allele frequencies were detected between each subgroup and the control group. No association is identified between OAS1 SNP and susceptibility to SPTB and PPROM.

    The analysis of circulating microparticles in pregnancy is of revolutionary potential because it represents an in vivo biopsy of active gestational tissues. We hypothesized that circulating microparticle signaling will differ in pregnancies that experience spontaneous preterm birth from those delivering at term and that these differences will be evident many weeks in advance of clinical presentation. Utilizing plasma specimens obtained between 10 and 12 weeks' gestation as part of a prospectively collected birth cohort in which pregnancy outcomes are independently validated by 2 board-certified maternal-fetal medicine physicians, 25 singleton cases of spontaneous preterm birth ≤ 34 weeks were matched by maternal age, race, and gestational age of sampling (±2 weeks) with 50 uncomplicated term deliveries. Circulating microparticles from these first-trimester specimens were isolated and analyzed by multiple reaction monitoring mass spectrometry for potential protein biomarkers following previous studies. Markers with robust univariate performance in correlating spontaneous preterm birth were further evaluated for their biological relevance via a combined functional profiling/pathway analysis and for multivariate performance. Among the 132 proteins evaluated, 62 demonstrated robust power of detecting spontaneous preterm birth in a bootstrap receiver-operating characteristic curve analysis at a false discovery rate of deliver spontaneously ≤ 34 weeks. These changes, with further validation, will allow the stratification of patients at risk of spontaneous preterm birth before clinical presentation. Copyright © 2016 Elsevier Inc.

    Full Text Available Immunological mechanisms have been proposed to underlie the pathogenesis of recurrent spontaneous abortion (RSA. Vitamin D has a potent immunomodulatory effect, which may affect pregnancy outcome. The objective of this study was to investigate 25-hydroxyvitamin D [25(OH D] concentration and vitamin D receptor (VDR expression in the decidual tissues of RSA patients. Thirty women with RSA (RSA group and thirty women undergoing elective abortion (control group were recruited during 2016 from gynecology outpatient clinics. We measured 25(OH D, interleukin (IL-17, IL-23, transforming growth factor β (TGF-β, VDR and 1-α-hydroxylase (CYP27B1 in decidual tissues collected during the abortion procedure. In the RSA group, 25(OH D and TGF-β were significantly decreased while IL-17 and IL-23 were significantly increased compared with the control group. VDR expression was significantly decreased in the RSA group compared with the control group. Logistic regression analysis showed a significant negative correlation between 25(OH D in decidual tissues and RSA. These results indicated that vitamin D concentrations in the decidua are associated with inflammatory cytokine production, suggesting that vitamin D and VDR may play a role in the etiology of RSA.

    Patients with PPROM are at risk for a variety of outcomes, including chorioamnionitis (CA), placental abruption (PA), or preterm labor (PTL). Competing risk regression can analyze a cohort's risk of individual outcomes while accounting for ongoing deliveries secondary to competing events. A secondary analysis of the subjects from MFMU BEAM study of neuroprotection after preterm birth (BEAM) with conservative PPROM management. Deliveries were categorized as: PA, CA, PTL, "elective" or "indicated". The association between outcomes of PA, CA or PTL and clinical predictors of twins, ethnicity, parity, gestational age at rupture, bleeding, contractions, cervical dilation, preterm birth history, weight, and genitourinary infections were evaluated via competing risk regression. 1970 subjects were included. The significance and directionality of predictors varied according to specific outcomes. Patients with twins had an increased PTL hazard (1.85) though reductions in CA- (0.66) or PA-specific (0.56) hazards. Decreased latency in African-Americans was almost entirely due to an increased CA hazard (1.44) without a significant association with PTL. Increasing gestational age at membrane rupture was associated with a decreasing hazard of CA although increasing hazard of PTL. For patients with PPROM, the hazards associated with different clinical predictors vary according to exact outcomes.

    Some spontaneous preterm deliveries (PTD) are caused by occult infections of the fetal membranes (histologic chorioamnionitis [HCA]). High levels of infection-related markers, including some cytokines, sampled from maternal circulation in mid-pregnancy have been linked to PTD, but whether these specifically identify HCA has not been established. We have tested associations between thirteen Th1, Th2 and Th17 cytokines and PTD with and without HCA in a prospective cohort study. The study sample included 926 Pregnancy Outcomes and Community Health Study subcohort women; women with medically indicated PTD or incomplete data excluded. A panel of cytokines was assessed using a multiplex assay in maternal plasma collected at 15–27 weeks of gestation. Severe HCA was scored by a placental pathologist blinded to clinical variables. Multivariable polytomous logistic regression was used to estimate adjusted odds ratios (OR) per 1 standard deviation (SD) increase in cytokine levels using a 5 level outcome variable: PTD <35 weeks with HCA, PTD <35 weeks without HCA, PTD 35–36 weeks with HCA, PTD 35–36 weeks without HCA, and term (referent). Interleukin (IL)-1β, IL-2, IL-12, interferon-γ, IL-4, IL-6 and transforming growth factor-β were all significantly associated with PTD <35 weeks with HCA, with ORs of 1.6 – 2.3 per SD increase. None of these were associated with PTD <35 weeks without HCA or PTD 35–36 weeks with HCA. Although the tissues of origin of circulating cytokines are unclear, the observed elevations across many cytokines among women who later delivered <35 weeks with HCA may represent a robust immune response to infection within gestational tissues. These results suggest that women with HCA could be identified using relatively non-invasive means. PMID:18814919

    The researchers conducted a cross-sectional survey to determine the relationship between handling heavy items during pregnancy and spontaneous abortion among working women in South Korea. One thousand working women were selected from a database of those eligible for maternity benefits under the National Employment Insurance Plan. Study results showed that handling heavy items during pregnancy was associated with an increased risk of spontaneous abortion after adjusting for general characteristics of the participants and their work environment. A collective effort is needed on the parts of employers, employees, occupational health nurses, and the government to protect working women from lifting heavy items while pregnant.

    Health authorities in numerous countries recommend periconceptional folic acid supplementation to prevent neural tube defects. The objective of this study was to examine the association of dietary folate intake and folic acid supplementation during different periods of pregnancy with the risk of spontaneous preterm delivery (PTD). The Norwegian Mother and Child Cohort Study is a population-based prospective cohort study. A total of 66,014 women with singleton pregnancies resulting in live births in 2002-2009 were included. Folic acid supplementation was self-reported from 26 weeks before pregnancy until pregnancy week 24. At gestational week 22, the women completed a food frequency questionnaire, which allowed the calculation of their average total folate intake from foods and supplements for the first 4-5 months of pregnancy. Spontaneous PTD was defined as the spontaneous onset of delivery between weeks 22+0 and 36+6 (n = 1,755). The median total folate intake was 313 μg/d (interquartile range IQR 167-558) in the overall population and 530 μg/d (IQR 355-636) in the supplement users. Eighty-five percent reported any folic acid supplementation from effect of dietary folate intake or folic acid supplementation on spontaneous PTD. Preconceptional folic acid supplementation starting more than 8 weeks before conception was associated with an increased risk of spontaneous PTD. These results require further investigation before discussing an expansion of folic acid supplementation guidelines.

    Humans are widely exposed to phthalates, bisphenol A and nonylphenol owing to the ubiquitous use of these chemicals in consumer products. Increasing attention has been paid to exposure to phthalates, bisphenol A and nonylphenol because of their potential adverse effects on human fertility. A validated method was developed to investigate the three classes of environmental estrogen, mentioned above, in the urine of Chinese women of Nanjing area with unexplained recurrent spontaneous abortion. Solid-phase extraction coupled with ultra performance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS) was used. In this method, amounts of bisphenol A (BPA), nonylphenol (NP) and four phthalate metabolites, mono-n-butyl phthalate (MBP), mono-isobutyl phthalate (MiBP), mono-benzyl phthalate (MBzP) and mono-2-ethylhexyl phthalate (MEHP), along with their isotope labeled internal standards, were measured using UPLC-MS/MS operated in negative electrospray ionization multiple reaction monitoring mode. The limits of detection were 0.3 ng/mL for the four phthalate metabolites, and 0.5 ng/mL for bisphenol A and nonylphenol. For women with unexplained recurrent spontaneous abortion, the mean concentrations of MBP, MiBP, MBzP, MEHP, BPA and 4-n-NP were 6.52±6.04, 5.51±4.19, 0.53±0.42, 10.12±4.16, 7.13±7.42, 0.41±0.49 ng/mL (mean±SD), respectively. For the control group, the mean concentrations of the corresponding analytes were 4.15±3.57, 2.96±3.30, 0.46±0.49, 6.50±2.81, 4.43±2.23,0.48±0.43 ng/mL (mean±SD), respectively. Levels of MiBP and MEHP were significantly different between the two groups, using Wilcoxon rank sum tests. This method can be applied in epidemiological studies to explore the association between exposure to environmental estrogens and relevant adverse outcomes. - Highlights: • Studied on the exposure level of six analytes in Chinese women with unexplained recurrent spontaneous abortion. • Differences in MEHP and MiBP urine levels were

    Detection of Ureaplasma, Mycoplasma and Candida spp. in the vagina during pregnancy has previously been associated with preterm birth (PTB). However, the prevalence of these microorganisms and the associated obstetric risks (likely to be population-specific) have not been determined in Australian women; furthermore, in the case of Ureaplasma spp., very few studies have attempted characterisation at the species level and none have examined genotype/serovar status to further refine risk assessment. In order to address these issues we sampled the vaginal fluid of 191 pregnant Australian women at three time points in pregnancy. Culture methods were used for detection of Ureaplasma spp. and Candida spp., and real-time PCR was used for speciation of U. parvum and U. urealyticum, non-albicans Candida spp., Mycoplasma hominis and Mycoplasma genitalium. High-resolution melt PCR was used to genotype U. parvum. Data on various lifestyle factors (including sex during pregnancy and smoking), antimicrobial use and pregnancy outcome were collected on all participants. Chi-square tests were used to assess the association of vaginal microorganisms with PTB. Detection of Ureaplasma spp. was higher among spontaneous PTB cases, specifically in the presence of U. parvum [77 % preterm (95 % confidence interval (CI) 50-100 %) vs. 36 % term (CI: 29-43 %), p = 0.004], but not U. urealyticum. The association with PTB strengthened when U. parvum genotype SV6 was detected (54 % preterm (CI: 22-85 %) vs. 15 % term (CI: 10-20 %), p = 0.002); this genotype was also present in 80 % (4/5) of cases of PTB Candida albicans in the same sample, the association with PTB remained strong for both U. parvum [46 % preterm (CI: 15-78 %) vs. 13 % term (CI: 8-18 %), p = 0.005] and U. parvum genotype SV6 [39 % preterm (CI: 8-69 %) vs. 7 % term (CI: 3-11 %), p = 0.003]. With the exception of Candida glabrata, vaginal colonisation status for all organisms was stable throughout

    Spontaneous preterm birth is a major cause of perinatal morbidity and mortality. It is unclear if a cervical pessary can reduce the risk of spontaneous preterm delivery. To test whether in asymptomatic women with singleton pregnancies and no prior spontaneous preterm birth but with short cervical length on transvaginal ultrasound, use of a cervical pessary would reduce the rate of spontaneous preterm birth at less than 34 weeks of gestation. Parallel-group, nonblinded, randomized clinical trial conducted from March 1, 2016, to May 25, 2017, at a single center in Italy. Asymptomatic women with singleton gestations, no previous spontaneous preterm births, and cervical lengths of 25 mm or less at 18 weeks 0 days to 23 weeks 6 days of gestation were eligible. Patients were randomized 1:1 to receive either cervical pessary (n = 150) or no pessary (n = 150). The pessary was removed between 37 weeks 0 days and 37 weeks 6 days of gestation or earlier if clinically indicated. The control group received standard care. For cervical length of 20 mm or shorter, women in both groups were prescribed vaginal progesterone, 200 mg/d, until 36 weeks 6 days of gestation. No bed rest or activity restriction was recommended. The primary end point was spontaneous preterm birth at less than 34 weeks of gestation. Secondary outcomes were adverse events. Among 300 women who were randomized (mean age, 29 [SD, 6.3] years; mean gestational age, 22 [SD, 1.3] weeks), 100% completed the trial. The primary end point occurred in 11 women (7.3%) in the pessary group and 23 women (15.3%) in the control group (between-group difference, -8.0% [95% CI, -15.7% to -0.4]; relative risk, 0.48 [95% CI, 0.24-0.95]). During follow-up, the pessary group had a higher rate of increased or new vaginal discharge (86.7% vs 46.0%; between-group difference, +40.7% [95% CI, +30.1%-+50.3%]; relative risk, 1.88 [95% CI, 1.57-2.27]).

    Results: Out of 51 subjects, 18 had positive Anti-TPO-Ab, of which -10 were among the cases and 8 belonged to the controls. Out of 18 women with positive AntiTG-Ab, 11 cases were in the control group and 7 were in the cases. The differences between the control group and the amounts of Anti-TPO-Abs (P=0.468 and Anti-TG-Abs (P=0.675 were not swignificant. Conclusion: The results revealed that there is no association between abortion and presence of antithyroid antibodies in mother’s serum. Other abortion causes such as various kinds of infections and smoking might be involved which requires more research.

    Full Text Available Aims: This study was aimed to explore the interaction between environment and CD28/B7 pathway to provide the potential epidemiology for prevention and treatment of recurrent spontaneous abortion (RSA. Methods: The retrospective study included 630 RSA cases and 1320 healthy women during their middle and late prenatal care. Their living environment was investigated, and the influence of environmental factors on pregnancy abortion was analyzed. The genomic DNAs were extracted from the study subjects, and the polymorphisms of CD28 and B7 were analyzed. Finally, the interaction of gene and environment on RSA was analyzed with the logistic regression analyses. Results: The multi-variate regression analysis indicated that vitamin supplement, intake of fresh fruits or vegetables, night shift, staying up late, history miscarriage, as well as history induced abortion were, independently, risk factors for RSA (all P< 0.05. Moreover, rs3116496 (T>C, rs3181098 (G>A and rs3181100 (G>C of CD28, rs1915087 (C>T of B7-2, as well as rs6804441 (A>G and rs41271391 (G>T of B7-1 were correlated with modified RSA risk (all P< 0.05. The haplotypes TGT and TAG could also regulate the risk of RSA (both P< 0.05. The synthetic influences of the aforementioned SNPs and environmental factors could also significantly affect the susceptibility to RSA (all P< 0.05. Conclusion: The interaction of environment and SNPs of CD28/B7 pathway on RSA risk was distinct from CD28/B7 pathway or environment alone.

    Full Text Available The mean birthweight of babies eventually born to couples with a history of recurrent spontaneous abortion (RSA is allegedly lower if the parents have a high degree of HLA antigen sharing (Reznikoff-Etievant et al., 1991, but this relationship has not been independently confirmed. We have re-investigated this question by analysing data from 36 families. In 22 instances, we were able to relate birthweight directly to feto-maternal HLA compatibility for the first time in such families. We were unable to confirm any appreciable influence of paternal or feto-maternal HLA sharing on birthweight or placental weight and conclude that RSA families do not differ markedly from normal families in this respect.

    Twenty-two nulli- all primipara who had had previous repeated spontaneous abortions and who did not have anti-HLA antibodies for the partner, received immunological treatment consisting of a single transfusion of the partner's lymphocytes in the third week of pregnancy, and giving natural progesterone supplements after the kinetic of Beta-HCG in the plasma had been assessed. The number of pregnancies which went to terme (94% success) was significantly better than those obtained in our first protocol which was to give one to three transfusions of the partner's lymphocytes before the pregnancy started (58% success rare after 24 treatments). Apart from obtaining much better results the second protocol made it possible to avoid giving a significant number of useless transfusions (22% of pre-conceptual transfusions were not followed by a pregnancy at all).

    This study aimed to determine the express level of tumour necrosis factor α (TNF- α ) in the decidual tissue and peripheral blood of patients with recurrent spontaneous abortion (RSA). Eighty RSA patients and 100 control women were recruited in this study. Enzyme-linked immunosorbent assay (ELISA) was applied to determine the expression level of TNF- α in peripheral blood and decidual tissues from both groups. Additionally, the expression level of TNF- α was compared between RSA patients with different numbers of abortions, as well as primary and secondary RSA patients. The expression level of TNF- α in peripheral blood and decidual tissues of RSA patients was significantly higher compared to the controls (p blood and decidual tissues at a similar level to patients who had experienced RSA three times (p > 0.05), but significantly lower than patients who had experienced RSA more than three times (p blood and decidual tissues was significantly higher in the secondary RSA patients, when compared with primary RSA patients (p tissue and peripheral blood may be one of the causes of RSA and therefore could be used as a clinical indicator.

    Preterm premature rupture of membranes is responsible for one third of preterm births. Ehlers-Danlos syndrome (EDS) is associated with preterm premature rupture of membranes in humans. Notably, an EDS variant is caused by a genetic mutation resulting in abnormal secretion of biglycan and decorin, two small leucine-rich proteoglycans highly expressed in reproductive tissues. Because biglycan/decorin null mutant (Bgn−/−Dcn−/−) mice demonstrate phenotypic changes similar to EDS, we utilized this model to test whether either or both biglycan and decorin play a role in the attainment of successful term gestation. Wild-type, biglycan null mutant, decorin null mutant and biglycan/decorin null mutant pregnancies were assessed for length of gestation, pup and placenta weight and litter size. Quantitative real-time polymerase chain reaction was performed to measure biglycan and decorin gene expression and immunohistochemistry was performed to assess protein expression in placenta and fetal membranes at embryonic day E12, E15 and E18. Bgn−/−Dcn−/− dams displayed preterm birth, whereas the possession of at least two biglycan or decorin wild-type alleles was protective of preterm birth. Bgn−/−Dcn−/− pups were decreased at postnatal day P1 but not at E18. Biglycan and decorin were upregulated in the placenta in each other’s absence and were developmentally regulated in fetal membranes, suggesting that these two proteoglycans demonstrate genetic complementation and contribute to gestational success in a dose dependent manner. Thus, the biglycan/decorin null mutant mouse is a model of genetically induced preterm birth and perinatal loss. This model presents novel targets for preventive or therapeutic manipulation of preterm birth. PMID:21502335

    Infants born preterm birth are the leading cause of mortality in children preterm birth by 33% in women with history of spontaneous preterm birth. We demonstrated previously that plasma concentrations of 17-alpha hydroxyprogesterone caproate vary widely among pregnant women and that women with 17-alpha hydroxyprogesterone caproate plasma concentrations in the lowest quartile had spontaneous preterm birth rates of 40% vs rates of 25% in those women with higher concentrations. Thus, plasma concentrations are an important factor in determining drug efficacy but the reason 17-alpha hydroxyprogesterone caproate plasma concentrations vary so much is unclear. Predominantly, 17-alpha hydroxyprogesterone caproate is metabolized by CYP3A4 and CYP3A5 enzymes. We sought to: (1) determine the relation between 17-alpha hydroxyprogesterone caproate plasma concentrations and single nucleotide polymorphisms in CYP3A4 and CYP3A5; (2) test the association between progesterone receptor single nucleotide polymorphisms and spontaneous preterm birth; and (3) test whether the association between plasma concentrations of 17-alpha hydroxyprogesterone caproate and spontaneous preterm birth varied by progesterone receptor single nucleotide polymorphisms. In this secondary analysis, we evaluated genetic polymorphism in 268 pregnant women treated with 17-alpha hydroxyprogesterone caproate, who participated in a placebo-controlled trial to evaluate the benefit of omega-3 supplementation in women with history of spontaneous preterm birth. Trough plasma concentrations of 17-alpha hydroxyprogesterone caproate were measured between 25-28 weeks of gestation after a minimum of 5 injections of 17-alpha hydroxyprogesterone caproate. We extracted DNA from maternal blood samples and genotyped the samples using TaqMan (Applied Biosystems, Foster City, CA) single nucleotide polymorphism genotyping assays for the following single nucleotide polymorphisms: CYP3A4*1B, CYP3A4*1G, CYP3A4*22, and CYP3A5*3; and rs

    To examine peak serum levels of the β-subunit of human chorionic gonadotropin (β-hCG) for prediction of early pregnancy outcomes among women with recurrent spontaneous abortion (RSA). In a retrospective study, the medical records of pregnant women with a history of RSA treated at Sun Yat-sen Memorial Hospital, China, between January 2011 and July 2013 were reviewed. Serum β-hCG had been measured twice weekly from 5 to 13weeks of pregnancy, and pregnancy was monitored by transvaginal ultrasonography to 13(+6)weeks. Optimal cutoff for peak β-hCG level was determined by receiver operator characteristic curve analysis and Youden index. Women were divided into four groups on the basis of optimal peak β-hCG cutoff and pregnancy outcome (pregnancy at 13weeks or spontaneous abortion). Peak β-hCG levels and length of pregnancy at this peak were examined. Overall, 1240 patients were included. The optimal cutoff value of peak β-hCG was 88 468IU/L, with a sensitivity, specificity, positive predictive value, and negative predictive value for successful pregnancy of 95.6%, 88.0%, 95.6%, and 89.0%, respectively. A faster rise in β-hCG, higher peak β-hCG, and longer pregnancy length at peak β-hCG were associated with successful early pregnancy. A cutoff value of serum β-hCG of 88 000IU/L could be used to predict early pregnancy outcomes for women with a history of RSA. Copyright © 2016. Published by Elsevier Ireland Ltd.

    To examine the associations between tobacco exposure and adverse pregnancy outcomes using quantitative measures of lifetime active smoking and secondhand smoke (SHS) exposure. Historical reproductive data on 80 762 women who participated in the Women's Health Initiative Observational Study were examined with a cross-sectional analysis. We assessed self-reported lifetime active and passive tobacco smoke exposure, self-reported spontaneous abortions, stillbirths and ectopic pregnancies. When compared with never-smoking women, participants who were ever active smokers during their reproductive years had ORs (OR) of 1.16 (95% CI 1.08 to 1.26) for 1 or more spontaneous abortions, 1.44 (95% CI 1.20 to 1.73) for 1 or more stillbirths, and 1.43 (95% CI 1.10 to 1.86) for 1 or more ectopic pregnancies. Never-smoking women participants with the highest levels of lifetime SHS exposure, including childhood >10 years, adult home >20 years and adult work exposure >10 years, when compared with never-smoking women with no SHS exposure had adjusted ORs of 1.17 (95% CI 1.05 to 1.30) for spontaneous abortion, 1.55 (95% CI 1.21 to 1.97) for stillbirth, and 1.61 (95% CI 1.16 to 2.24) for ectopic pregnancy. Women who were ever-smokers during their reproductive years had significantly greater estimates of risk for spontaneous abortion, stillbirth and tubal ectopic pregnancy. Never-smoking women with the highest levels of lifetime exposure to SHS had significantly increased estimates of risk for spontaneous abortion, stillbirth and tubal ectopic pregnancy.

    Full Text Available Abstract The highly pathogenic avian influenza H5N1 virus is one of candidates for future pandemic. Since H5N1 viruses had previously been isolated only from avian species, the outbreak raised questions about the ability of these viruses to cause severe disease and death in humans. Pregnant women are at increased risk for influenza-associated illness and death. However, little is known about whether influenza viruses could transmit to the fetus through the placenta, and the effects of abortion and preterm delivery to maternal influenza infection are not well understood. We found that the H5N1 viruses could vertical transmit to the fetus through the placenta in the BALB/c mouse model, and the viruses could partly be evacuated by the pregnant mice during abortion or preterm delivery. This study may further our understanding about the transmission of this highly pathogenic avian influenza viruses, supply optimized clinical treatment method for pregnant women, and shed some light on better preventing and controlling for future potential outbreak of H5N1 influenza pandemic.

    Many adverse pregnancy outcomes (APOs), including spontaneous preterm birth (PTB), are associated with placental dysfunction. Recent clinical and experimental evidences suggest that premature aging of the placenta may be involved in these events. Although placental aging is a well-known concept, the mechanisms of aging during normal pregnancy and premature aging in APOs are still unclear. This review was conducted to assess the knowledge on placental aging related biochemical changes leading to placental dysfunction in PTB and/or preterm premature rupture of membranes (pPROM). We performed a systematic review of studies published over the last 50 years in two electronic databases (Pubmed and Embase) on placental aging and PTB or pPROM. The search yielded 554 citations, 30 relevant studies were selected for full-text review and three were included in the review. Only one study reported oxidative stress-related aging and degenerative changes in human placental membranes and telomere length reduction in fetal cells as part of PTB and/or pPROM mechanisms. Similarly, two animal studies reported findings of decidual senescence and referred to PTB mechanisms. Placental and fetal membrane oxidative damage and telomere reduction are linked to premature aging in PTB and pPROM but the risk factors and biomolecular pathways causing this phenomenon are not established in the literature. However, no biomarkers or clinical indicators of premature aging as a pathology of PTB and pPROM have been reported. We document major knowledge gaps and propose several areas for future research to improve our understanding of premature aging linked to placental dysfunction. Copyright © 2015 Elsevier Ltd.

    Full Text Available Abstract Background The Medical Research Council (MRC ORACLE trial evaluated the use of co-amoxiclav 375 mg and/or erythromycin 250 mg in women presenting with preterm rupture of membranes (PROM ORACLE I or in spontaneous preterm labour (SPL ORACLE II using a factorial design. The results showed that for women with a singleton baby with PROM the prescription of erythromycin is associated with improvements in short term neonatal outcomes, although co-amoxiclav is associated with prolongation of pregnancy, a significantly higher rate of neonatal necrotising enterocolitis was found in these babies. Prescription of erythromycin is now established practice for women with PROM. For women with SPL antibiotics demonstrated no improvements in short term neonatal outcomes and are not recommended treatment. There is evidence that both these conditions are associated with subclinical infection so perinatal antibiotic administration may reduce the risk of later disabilities, including cerebral palsy, although the risk may be increased through exposure to inflammatory cytokines, so assessment of longer term functional and educational outcomes is appropriate. Methods The MRC ORACLE Children's Study will follow up UK children at age 7 years born to 4809 women with PROM and the 4266 women with SPL enrolled in the earlier ORACLE trials. We will use a parental questionnaire including validated tools to assess disability and behaviour. We will collect the frequency of specific medical conditions: cerebral palsy, epilepsy, respiratory illness including asthma, diabetes, admission to hospital in last year and other diseases, as reported by parents. National standard test results will be collected to assess educational attainment at Key Stage 1 for children in England. Discussion This study is designed to investigate whether or not peripartum antibiotics improve health and disability for children at 7 years of age. Trial registration The ORACLE Trial and Children

    Post-abortum hemorrhage is a common clinical situation and etiological diagnosis has to be made early to avoid further complications such as persistent bleeding, infection or adhesions that may compromise fertility. Retained products of conception are the most common cause of bleeding. The diagnosis is based on endovaginal color doppler ultrasound showing a thickened and hypervascular endometrial echo-complex extending partly to the myometrium. The main differential diagnosis is uterine arteriovenous malformation, mostly iatrogenic. Diagnosis is based on the presence of myometrial confluent cystic lesions filled with turbulent and high velocity arterial flow on endovaginal color doppler ultrasound. The distinction between these two etiologies of post-abortion bleeding is mandatory because of totally different treatment: typically medical and/or surgical in case of retained products of conception and by selective arterial embolization in case of vascular malformation.

    The aim of this study was to explore the association of the DNA-methyltransferase (DNMT)-3A and DNMT3B promoter polymorphisms with the risk of human spontaneous abortion after assisted reproduction techniques (ARTs) and natural conception. We collected tissues from women who underwent abortion procedures: (a) chorionic villus samples (CVS) and muscle samples (MS) from spontaneous abortions conceived by ART and natural cycle (study group), n = 152; and (b) CVS and MS from normal early pregnancy and second trimester (control group), n = 155. The single-nucleotide polymorphism (SNP) -448A > G in the DNMT3A promoter region and -149C/T polymorphism of DNMT3B were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and confirmed by sequencing. The allele frequency of -448A among pregnancy loss group and control group was 34.2 % vs. 16.5 %, respectively. Compared with GG carriers, the DNMT3A -448AA homozygotes had an about 16-fold increased risk of spontaneous abortion [odds ratio (OR) = 16.130, 95 % confidence interval (CI), 3.665-70.984], and AG heterozygotes had an OR of 2.027 (95 % CI, 1.247-3.293). However, the distribution of -448A > G in individuals derived from ART pregnancies was not statistically significantly compared with those derived from spontaneous pregnancies (P = 0.661). For DNMT3B, we observed genotype frequencies of 100 % (TT) in the study group and the control group. The DNMT3A -448A > G polymorphism may be a novel functional SNP and contribute to its genetic susceptibility to spontaneous abortion in Chinese women, and ART may not affect the distribution of -448A > G in pregnancy loss and normal pregnancy. The observed TT genotype of DMNT3B suggests that this is the predominant genotype of this population. The findings provide new insights into the etiology of human spontaneous abortion.

    To investigate the relation of prior intracervical procedures with very preterm birth. A population-based case-control study. The study was conducted in Australia between 2002 and 2004. Three hundred and forty-five women having a medically indicated and 236 having a spontaneous singleton birth between 20 and 31 weeks of gestation and 796 women selected randomly from all those giving birth at ≥37 weeks of gestation. Interview data were analysed using logistic regression. Very preterm birth. Very preterm birth was significantly associated with having any intracervical procedure [adjusted odds ratio (AOR) 2.07; 95% confidence interval (CI) 1.6-2.7], in particular curettage associated with abortion (AOR 1.80; 95% CI 1.2-2.6). Assisted reproductive technology procedures were significantly associated with medically indicated very preterm birth (AOR 3.07; 95% CI 1.8-5.3) and treatments for precancerous cervical changes were significantly associated with spontaneous very preterm birth, as follows: conization/cone biopsy (AOR 3.33; 95% CI 1.8-6.2) and cauterization/ablation (AOR 2.27; 95% CI 1.4-3.8). Suction aspiration for abortion, abnormal Pap smear without treatment and abortion without instrumentation were not associated with very preterm birth. Intracervical procedures are associated with very preterm birth. Notably, curettage rather than any other procedure associated with abortion appears to be implicated in the risk. The introduction of infection during cervical procedures may be the common link with risks found. Changing clinical practice in the management of abortion and human papillomavirus vaccination may lead to lowering the risks of very preterm birth. © 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

    Do assisted reproduction techniques (ARTs) affect DNA methylation of imprinted genes and does aberrant methylation of imprinted genes account for the incidence of human spontaneous abortion (SA)? Our results show that imprinting errors of imprinted genes may contribute to human SA, and the occurrence of aberrant methylation of imprinted genes in ART pregnancies was comparable with that in natural pregnancies. Animal data and human studies demonstrated that in vitro culture of embryos can cause methylation defects in individual genes, which might affect subsequent embryonic development and contribute to SA. However, our previous studies showed an abnormal methylation pattern of PEG1 in human aborted chrionic villus samples (CVS) but an increased occurrence of aberrant methylation in CVS from ART-derived pregnancies was not observed. CVS were collected from women who underwent abortion procedures in the Department of Gynecology and Obstetrics in Nanfang Hospital from May 2008 to July 2011. Muscle samples (MS) were obtained from aborted fetuses and stillbirths. The samples were divided into four experimental groups: (A) SA/stillbirth after ART (n = 75), (B) multi-fetal reduction after ART (n = 73), (C) SA/stillbirth of natural pregnancies (n = 90) and (D) induced abortion (IA) of natural pregnancies (n = 82). The mean ± SD age of patients was 31.0 ± 4.1 (range: 18-45 years). The DNA methylation patterns of one paternally methylated (H19) and two maternally methylated (LIT1 and SNRPN) genes were analyzed in CVS and MS using pyrosequencing and bisulfite sequencing PCR. Clear hypo-methylation (90%) were not detected in LIT1 and SNRPN but two regions of hyper-methylation (91.7 and 91.4%) were observed in H19. The mean percentage of methylation in the SA samples (groups A and C) was higher than that in the IA samples (groups B and D; P<0.05). Box plot analyses showed that in the 165 SA samples, methylation values for 40/495 (8.1%) differentially methylated regions of the

    Full Text Available Objective: To study miR-155 expression in villus tissue of patients with recurrent spontaneous abortion and its relationship with apoptosis molecules and angiogenesis molecules. Methods: 40 cases of patients with unexplained recurrent spontaneous abortion were selected as URSA group, 30 cases of normal early pregnant women receiving artificial abortion were selected as control group, and villus tissue was collected to detect expression levels of miR-155, apoptosis molecules (Bcl-2, Bcl-xl, Bax, Bad, Fas and FasL and angiogenesis molecules (HIF-1 α, VEGF and sFlt-1. Results: MiR-155 expression level in villus tissue of URSA group was significantly lower than that of control group and the more the times of abortion, the lower the miR-155 expression level; pro-apoptosis molecules Bax, Bad, Fas and FasL expression levels in villus tissue of URSA group were higher than those of control group and negatively correlated with miR-155 expression level, and anti-apoptosis genes Bcl-2 and Bcl-xl expression levels were lower than those of control group and positively correlated with miR-155 expression level; HIF-1 α and VEGF expression levels in villus tissue of URSA group were lower than those of control group and positively correlated with miR-155 expression level, and sFlt-1 expression level was higher than that of control group and negatively correlated with miR-155 expression level. Conclusions: MiR-155 is lowly expressed in villus tissue of patients with recurrent spontaneous abortion, and miR-155 may be involved in the occurrence and development of the disease through regulating the expression of apoptosis molecules and angiogenesis molecules.

    This study aimed to detect the correlation between human papillomavirus (HPV) and spontaneous preterm labor in Egyptian women and its association to the human papilloma viral load and MPP2 gene expression. We performed an observational comparative case-control study in Department of Obstetric and Gynecology, Mansoura University Hospitals over women presented with spontaneous preterm labor, besides females admitted for giving birth at full term to detect conserved sequence in HPV-L1 gene (GP5/GP6) followed by genotype detection of high- and low-risk HPVs with quantification of the viral load and the MMP2 gene expression using real-time polymerase chain reaction (PCR). The prevalence of HPV was 18.1% in preterm females, but only 4% in full-term women (p value = 0.019*). Twenty percent were PCR positive for HPV 16 and 40% for HPV 18 whereas none of the control was positive for any of the studied high-risk genotypes. Thirty percent were PCR positive for HPV 6 and 10% were positive for HPV 11. MMP2 gene expression was significantly higher in preterm than full term. Human papilloma viral load was found to be positively correlated to the rate of MMP2 expression and the gestational age was significantly related to the viral load and the rate of expression of MMP2 gene. Human pabilloma virus especially high-risk genotypes was correlated to spontaneous preterm labor in Egyptian females through increasing early expression of MMP2 gene. The time of occurrence of preterm labor was affected by the viral load and so the rate of expression of MMP2 gene.

    Intraplacental choriocarcinoma is a rare malignant tumor diagnosed after an abortion, an ectopic pregnancy, or a term or preterm pregnancy or following the diagnosis of a hydatidiform mole. During pregnancy, it may be more common than reported, as most patients are asymptomatic and placental choriocarcinomas are usually inconspicuous macroscopically and are often mistaken for an infarct. Based upon a case study methodology, we describe 2 cases of intraplacental choriocarcinoma: the first case was identified in the product of a uterine curettage following an incomplete miscarriage and the second in one of the placentas of a bichorionic twin pregnancy. Maternal investigation did not reveal evidence of metastatic disease and neither did the infants' one in the second case. The two cases underwent maternal surveillance with serum hCG and remained disease-free until the present. In conclusion, intraplacental choriocarcinoma is easily underdiagnosed but with current treatment, even in the presence of metastasis, the prognosis is excellent. A routine microscopic examination of all the placentas and products of miscarriage can increase the real incidence of this entity and consequently improve its management. PMID:28567059

    Full Text Available Introduction: One of the causes of recurrent spontaneous abortions (RSA is an infection by the toxoplasmosis Protozoa. In comparison, we present detailed results using real-time polymerase chain reaction (PCR methods of detection. In this study, it was tried to detect Toxoplasma gondii (T. gondii by real-time PCR methods in patients with RSA. Methods: Amniotic fluid sampling was performed in the 16-20th weeks of gestation in 50 pregnant women with a history of RSA. The extracted deoxyribonucleic acid (DNA samples were analyzed using quantitative real-time PCR. Results: In all the cases, the detection of T. gondii was negative in the peripheral blood, and amniotic fluid samples by using the molecular methods (real-time PCR. Using the serological detection methods, 6% of patients were diagnosed as positive for the immunoglobulin M (IgM antibody. In addition, the IgG antibody was positive in 46% of the patients. Conclusion: It can be concluded that the serological methods lack specificity.

    From early pregnancy, maternal hemodynamic profile begins to change. The absence of these changes leads to increased risk of complication during the gestation. Aim of this study is to understand in early pregnancy the behaviour of total vascular resistances (TVR) as a sign of maternal cardiovascular adaptation to pregnancy. A cross section study was conducted. We followed 160 healthy women with singleton pregnancy during the first trimester of gestation. We evaluated cardiac output (CO) and TVR at 7, 9 and 11 weeks of gestation. We obtained the following haemodynamic measurements with the USCOM system, a non invasive method: heart rate (HR), systolic and diastolic blood pressure (SBP, DBP), CO and TVR. 160 healthy pregnant women were selected, 8 patients, were excluded for a bad signal. Absolute values of the haemodynamic measures are shown in Fig. 1. 41 patients underwent spontaneous embryonic demise. This last group of patients showed in 54% (group A) TVR values within the normal limits (TVR1200) and CO values below the normal adaptation to pregnancy. Table 1 shows hemodynamic measures for the group A and group B; we found differences in term of CO, TVR and PAS between the two groups. Elevated TVR might indicate an abnormal vascular adaptation already in first weeks of pregnancy. Moreover, in women who undergo to abortion, elevated TVR could be use to distinguish genetic or environmental causes of miscarriage. Copyright © 2013. Published by Elsevier B.V.

    Full Text Available BACKGROUND: Medications may be consumed periconceptionally before a woman knows she is pregnant. In this study, the authors evaluate the association of a prescription diet drug (Letigen containing ephedrine (20 mg and caffeine (200 mg with spontaneous abortion (SAB in the Danish National Birth Cohort. METHODS: Women were recruited during their first prenatal visit from 1996-2002. Pre-conception and early pregnancy medication use was reported on the enrollment form, and pregnancy outcome was determined by linking the mother's Civil Registration Number to the Medical Birth Registry and the National Hospital Discharge Register. Of 97,903 eligible pregnancies, 4,443 ended in SAB between 5 and 20 completed gestational weeks, inclusive. Letigen use was reported for 565 pregnancies. Cox regression models accounting for left truncation were fit to estimate the effect of pre-conception and early pregnancy Letigen use on SAB. PRINCIPAL FINDINGS: The estimated maternal age-adjusted hazard ratio for SAB was 1.1 (95% confidence interval 0.8-1.6 for any periconceptional Letigen use compared to no periconceptional use. CONCLUSIONS: Although Letigen has high levels of caffeine (the recommended 3 pills/day are approximately equivalent to caffeine from 6 cups of coffee, periconceptional use does not appear to be associated with an appreciably increased hazard of clinically recognized SAB.

    2009-11-01

    Full Text Available Abstract Introduction If left untreated, severe combined immunodeficiency can lead to an acute susceptibility to infection. The intrauterine environment is sterile until the amniotic membranes rupture. The vaginal flora then ascends into the genital tract, thus increasing the risk of chorioamnionitis. An extremely premature and prolonged membrane rupture is associated with a dismal prognosis for an immunocompetent preterm fetus. There are no case reports to date that detail the outcome of an immunocompromised preterm baby following prolonged rupture of membranes. Case presentation We present the case of a 32-year-old Indian woman who delivered a 31-week gestational baby who had a severe combined immunodeficiency following premature prelabour prolonged rupture of the membranes at the 14th week of gestation. Conclusion Extreme preterm prelabour spontaneous rupture of membranes in an underlying condition of severe combined immunodeficiency does not necessarily lead to an unfavourable outcome.

    The aim of this study was to investigate the relationship between the characteristics of spontaneous movements in preterm infants at term age and developmental delay at 3 years of age. We analysed video recordings of the spontaneous movements in the supine position of 124 preterm infants (44 males, 80 females) at 36 to 44 weeks postmenstrual age (PMA). The infants were born preterm (22-36wks PMA; birthweight 489-1696g) and had not received a diagnosis of a neurological or developmental disorder by the age of 3 years. The recorded spontaneous movements were quantified using six movement indices, which were calculated from two-dimensional trajectories of all limbs. The infants were divided into three developmental groups, normal, borderline, or delayed, based on their developmental quotient as calculated using the Kyoto Scale of Psychological Development 2001 (Kyoto Scale) at 3 years of age. Group differences in the movement indices were analysed. In the delayed group, average velocity of arms and legs were significantly lower (ppreterm infants. © 2013 Mac Keith Press.

    Spontaneous abortion (SA) occurs before 20 gestational weeks. Approximately, half of recurrent SA has no identifiable cause. No report has yet been investigated the possible involvement of lncRNA in pregnancy loss. Sixteen pairs of pregnancies with spontaneous abortions (SA) and induced abortions (IA) were studied. Embryonic sacs and decidua were collected for each pregnancy. A Human LncRNA Array was employed to profile genomewide lncRNAs, which were then validated by RT-PCR. Differentially expressed lncRNAs were identified. Biological pathways were categorized into six major groups: infection and inflammation, metabolism, signaling and transcriptional regulation, smooth muscle contraction, cell process, and coagulation. Infection and inflammation pathways regulated by lncRNAs were determined as the predominant pathogenetic factors underlying the SA. Finding that antisense lncRNAs have been either up- or down-regulated suggests that they may have both cis- and trans-regulations. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    We investigated the expression of methyl transferase G9a and methylated histone H3-K9 in fresh human decidual/endometrial tissue of 12 normal early pregnancies and 15 unexplained recurrent spontaneous abortions (URSA). The samples were obtained through dilatation and curettage and collected as per strict inclusion-exclusion criteria. The tissue was subjected to immunohistochemical analysis (IHC), western blotting (WB) and RT-PCR analysis. The results demonstrated methyl transferase G9a to have a lower expression in abortions when compared with that in normal pregnancy (P K9 was significantly lower (P < 0.0001) in URSA tissues than in controls. This study suggests that methylation may cause URSA and indicates the need for further work to explore the role of methylation in URSA and its possible prevention through locally acting methylating/demethylating agents.

    This work was motivated by observational studies in pregnancy with spontaneous abortion (SAB) as outcome. Clearly some women experience the SAB event but the rest do not. In addition, the data are left truncated due to the way pregnant women are recruited into these studies. For those women who do experience SAB, their exact event times are sometimes unknown. Finally, a small percentage of the women are lost to follow-up during their pregnancy. All these give rise to data that are left trunca...

    Full Text Available Cell-free fetal DNA and cell-free total DNA in maternal circulation have been proposed as potential markers for noninvasive monitoring of the placental condition during the pregnancy. However, the correlation of and change in cell-free fetal DNA and cell-free total DNA in spontaneous abortion (SA with fetal chromosomal aneuploidy have not yet been reported. Therefore, we investigated cell-free fetal DNA and cell-free total DNA levels in SA women with fetal chromosomal aneuploidy.A nested case-control study was conducted with maternal plasma collected from 268 women in their first trimester of pregnancy. Subjects included 41 SA with normal fetal karyotype, 26 SA with fetal chromosomal aneuploidy, and 201 normal controls. The unmethylated PDE9A gene was used to measure the maternal plasma levels of cell-free fetal DNA. The GAPDH gene was used to measure the maternal plasma levels of cell-free total DNA. The diagnostic accuracy was measured using receiver-operating characteristic (ROC curves. Levels of cell-free fetal DNA and cell-free total DNA were significantly higher in both SA women with normal fetal karyotype and SA women with fetal chromosomal aneuploidy in comparison with the normal controls (P<0.001 in both. The correlation between cell-free fetal DNA and cell-free total DNA levels was stronger in the normal controls (r = 0.843, P<0.001 than in SA women with normal karyotype (r = 0.465, P = 0.002 and SA women with fetal chromosomal aneuploidy (r = 0.412, P = 0.037. The area under the ROC curve for cell-free fetal DNA and cell-free total DNA was 0.898 (95% CI, 0.852-0.945 and 0.939 (95% CI, 0.903-0.975, respectively.Significantly high levels of cell-free fetal DNA and cell-free total DNA were found in SA women with fetal chromosomal aneuploidy. Our findings suggest that cell-free fetal DNA and cell-free total DNA may be useful biomarkers for the prediction of SA with fetal chromosomal aneuploidy, regardless of fetal

Spontaneous PTD was defined as delivery before 37 weeks due to spontaneous preterm labor or premature rupture of membranes. Patient with multifetal gestation and those with medically indicated term or PTD were excluded. Of 877 women meeting the inclusion criteria, 173 delivered preterm and 704 delivered at term, and 8.1% had high free β-hCG in one or both trimesters. High maternal first and/or second trimester free β-hCG (≥95th percentile) was associated with lower rates of PTD. Thirty-two women with high free β-hCG in both first and second trimesters delivered at term. Gestational age at delivery and birth weights were lower in women who did not have high free β-hCG in any trimester. Low free β-hCG (≤5th percentile) in either trimester was not associated with an increased or decreased likelihood of PTD. Logistic regression demonstrated an independent association of high free β-hCG (≥95th percentile) with a reduced likelihood of PTD. Stratified analysis revealed a stronger impact of this association in women with no prior history of PTD. High free β-hCG, in the absence of risk factors for medically indicated PTD, is associated with a reduced likelihood of spontaneous PTD and may represent a marker indicating lower risk.

    We reviewed women with previable spontaneous premature rupture of membranes (sPPROM) in whom an amniopatch was performed and compared their pregnancy outcomes with a conservative management group. Amniopatch, an amnioinfusion of autologous platelet concentrate followed by cryoprecipitate, was performed in 7 women with sPPROM diagnosed at 17-23 weeks' gestation, including one twin pregnancy. Three patients had incompetent cervices and the other 4 patients had sPPROM without incompetent cervices. Pregnancy outcomes of the cases were compared with the controls who were managed conservatively (n = 22). Amniopatch treatment was successful in 1 of 7 cases (14.3%), in which the ruptured membranes were completely sealed and the patient delivered a healthy baby at 39 weeks' gestation. No procedure-related complications were observed. Overall, neonatal outcome was similar in the amniopatch and conservatively managed groups, although the incidences of early neonatal sepsis and respiratory distress syndrome were lower in the amniopatch group. The overall success rate of amniopatch among our small number of cases was low. However, if successful, amniopatch may prolong a pregnancy with previable sPPROM to term. Copyright © 2012 S.

    New tools are required to identify women at increased risk of spontaneous preterm birth (sPTB). Quantitative texture analysis by ultrasound has been used to extract robust features from the ultrasound image of a given tissue to detect subtle changes in its microstructure. This may also be applied to the cervix. We aimed to determine if there is an association between quantitative analysis of the cervical texture (CTx) by ultrasound in the mid-trimester of pregnancy and sPTB quantitative analysis of the CTx. A learning algorithm was developed to obtain the best combination of cervical textures features associated with sPTB based on feature transformation and discriminant analysis-regression. The ability of the learning algorithm to predict sPTB was evaluated using a leave-one-out cross-validation technique, obtaining a CTx-based score for each individual. Receiver-operating characteristic (ROC) curves were drawn and sensitivity, specificity, positive and negative likelihood ratios were calculated for the optimal cut-off based on the ROC curve. The results were compared to those obtained with the CL. At all points the investigators studying the images were blinded to pregnancy outcome. Images of 310 women (27 cases and 283 controls) were of sufficient quality and included in the study. Median CTx-based score (-1.01 vs -0.07, p = Quantitative analysis of the cervical texture is able to extract information from the ultrasound images related to sPTB and generate a CTx-based score which is independently associated to sPTB.

    In this secondary analysis of data from a double-blind randomized controlled trial carried out in northern China, we aimed to assess the effect of prenatal supplementation with multiple micronutrients (MMN) or iron + folic acid (IFA), versus folic acid (FA) alone, on risk of spontaneous preterm birth (SPB) and the impact of supplementation timing on SPB. A total of 18,775 nulliparous pregnant women enrolled between 2006 and 2009 were randomly assigned to receive daily FA, IFA, or MMN from the period before 20 weeks' gestation to delivery. The incidences of SPB for women consuming FA, IFA, and MMN were 5.7%, 5.6% and 5.1%, respectively. Compared with women given FA, the relative risks of SPB for those using MMN and IFA were 0.99 (95% confidence interval: 0.85, 1.16) and 0.89 (95% confidence interval: 0.79, 1.05), respectively. SPB incidence in women who started consuming FA, IFA, and MMN before the 12th week of gestation (4.6%, 4.2%, and 3.9%, respectively) was significantly reduced compared with starting supplement use on or after the 12th gestational week (6.9%, 7.2%, and 6.4%, respectively). Starting use of FA, IFA, or MMN supplements before the 12th week of gestation produced a 41%-45% reduction in risk of SPB. Early prenatal enrollment and micronutrient use during the first trimester of pregnancy appeared to be of particular importance for prevention of SPB, regardless of supplement group. © The Author(s) 2017.

    Full Text Available Background: Disorders in immune system regulation may result in pregnancy abnormalities such as recurrent spontaneous abortion (RSA. This study aims to determine the ratio of regulatory T (Treg and T helper (Th 17 cells in unexplained RSA (URSA women during proliferative and secretory phases of their menstrual cycles compared to healthy non-pregnant women. Materials and Methods: In this case control study, 25 women with URSA and 35 healthy, non-pregnant women were enrolled. The percentage of Th17 and Treg cells in participants peripheral blood were determined by flow cytometry. Results: The percentage of Th17 cells and their related cytokines in serum (IL-17A were higher in the proliferative and secretory phases of the menstrual cycles of URSA women compared to the control women. However, a lower percentage of Treg cells and their related cytokines in serum, transforming growth factor (TGF β1 and interleukin (IL-10 were detected in the proliferative but not the secretory phase of the URSA group. The ratio of Th17/CD4+ Treg was higher in the URSA group than the control group. We observed an increased ratio of Th17/CD4+ Treg during the proliferative and secretory phases in URSA women. Conclusion: The imbalance between Th17 and Treg cells during the proliferative phase of menstrual cycles in the URSA group may be considered a cause for spontaneous abortion.

    Full Text Available Background & aim: Preterm delivery is one of the most important problems in pregnancy, as it is the primary cause of 75% of prenatal mortality and morbidities. This study aimed to determine the prevalence and risk factors for preterm delivery in Tehran, Iran. Methods:In this cross-sectional study performed in eight random hospitals from five different regions of Tehran (North, South, West, East, and center, the prevalence of preterm delivery was evaluated and the most frequent risk factors were identified. Samples were divided into preterm delivery (n=140 and term delivery (n=100 groups. Questionnaires were completed through interviews with mothers and using patient records. To analyze the data, Chi-square test was run, using SPSS version 16. Results: About 13,281 deliveries were included in the study. The highest and lowest prevalence of preterm delivery were 6.30% and 0.77% in the North and East regions of Tehran, respectively.  The overall prevalence of preterm delivery was 1.52% in Tehran. In the preterm group, age ≥35 years, pre-mature rupture of membranes, bleeding, gestational hypertension, history of preterm delivery and abortion, multiple pregnancy, and preeclampsia were significantly more frequent than the term delivery group. Conclusion: Spontaneous preterm birth was one of the major causes of maternal and neonatal morbidity; therefore, identification of its risk factors would be beneficial.

The results demonstrated that SSRIs increase the risk of spontaneousabortion and major malformations during pregnancy while they don’t increase the risk of cardiovascular malformations and minor malformations. Our previous meta-analysis only showed an increase in the risk of spontaneous abortion following the use of SSRIs duringpregnancy. This might be due to increase in the number of studies included or addition of two new SSRIs (citalopram and escitalopram. The message to researchers is to try considering SSRIs individually during pregnancy to reduce heterogeneity, although all are aware ofinevitable limitations to study on pregnant mothers.

    The objective was to investigate the subsets of natural killer T (NKT)-like cells and the expression of Th1/Th2 cytokines in the peripheral blood (PB) and/or decidual tissue of patients with unexplained recurrent spontaneous abortion (URSA). The percentages of NKT-like cells in the PB and deciduas of URSA patients in early pregnancy and in the PB of nonpregnant women were analyzed by flow cytometry. The expression of interferon (IFN)-γ (Th1 cytokine) and Th2 cytokines, interleukin (IL)-4 and IL-10, in the PB and decidual tissue was measured by quantitative RT-PCR and enzyme-linked immunosorbent assay (ELISA). Most percentages of subsets of NKT-like cells (CD3(+)CD56(+), CD3(+)CD56(+)CD16(+)) in the PB and deciduas were significantly greater in URSA patients than in normal pregnant and nonpregnant women. A cut-off value of 3.75% for the increased percentage of CD3(+)CD56(+)CD16(+) NKT-like cells in the PB appeared to be predictive of pregnancy failure. Moreover, we found that in the decidua, IFN-γ expression was significantly higher, while IL-4 and IL-10 expression was significantly lower in URSA patients compared with those with a normal pregnancy. The ratio of decidual Th1/Th2 cytokines in URSA patients was significantly increased compared with that in normal pregnant women. Decidual IL-4 expression correlated negatively with the percentages of blood CD3(+)CD56(+)CD16(+) NKT-like cells and the decidual CD3(+)CD56(+) and CD3(+)CD56(+)CD16(+) NKT-like cells. NKT-like cells may play an important role in maintaining normal pregnancy. Measurement of CD3(+)CD56(+)CD16(+) NKT-like cells in the PB may provide a potential tool for assessing patients' risk of spontaneous abortion. Copyright © 2015. Published by Elsevier Ireland Ltd.

    To investigate reproductive outcomes in women following induced abortion (IA). Retrospective cohort study. Hospital admissions between 1981 and 2007 in Scotland. Data were extracted on all women who had an IA, a miscarriage or a live birth from the Scottish Morbidity Records. A total of 120 033, 457 477 and 47 355 women with a documented second pregnancy following an IA, live birth and miscarriage, respectively, were identified. Obstetric and perinatal outcomes, especially preterm delivery in a second ongoing pregnancy following an IA, were compared with those in primigravidae, as well as those who had a miscarriage or live birth in their first pregnancy. Outcomes after surgical and medical termination as well as after one or more consecutive IAs were compared. IA in a first pregnancy increased the risk of spontaneous preterm birth compared with that in primigravidae (adjusted RR (adj. RR) 1.37, 95% CI 1.32 to 1.42) or women with an initial live birth (adj. RR 1.66, 95% CI 1.58 to 1.74) but not in comparison with women with a previous miscarriage (adj. RR 0.85, 95% CI 0.79 to 0.91). Surgical abortion increased the risk of spontaneous preterm birth compared with medical abortion (adj. RR 1.25, 95% CI 1.07 to 1.45). The adjusted RRs (95% CI) for spontaneous preterm delivery following two, three and four consecutive IAs were 0.94 (0.81 to 1.10), 1.06 (0.76 to 1.47) and 0.92 (0.53 to 1.61), respectively. The risk of preterm birth after IA is lower than that after miscarriage but higher than that in a first pregnancy or after a previous live birth. This risk is not increased further in women who undergo two or more consecutive IAs. Surgical abortion appears to be associated with an increased risk of spontaneous preterm birth in comparison with medical termination of pregnancy. Medical termination was not associated with an increased risk of preterm delivery compared to primigravidae.

    Teenage abortions predispose women to adverse pregnancy outcomes in subsequent pregnancies such as anemia, stillbirths, preterm deliveries and low birth weight babies. We aim to profile the women presenting for abortions in our institution and determine risk factors for late presentation for abortions. In this retrospective cohort study, all women who underwent an abortion at the National University Hospital, Singapore, from 2005 to 2009 were recruited. Data was obtained from a prepared questionnaire during the mandatory pre-abortion counseling sessions. Profiles of women aged singlehood, nulliparity and lack of prior usage of contraception. Teenagers are more likely to have no prior contraceptive usage and to present late for abortions. Lack of proper sexual education and awareness of contraceptive measures may have a major contributory factor to such a trend in teenage abortions. Recommendations have been made in order to curb this societal problem. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  7. Active suppression of host-vs-graft reaction in pregnant mice. VII. Spontaneous abortion of allogeneic CBA/J x DBA/2 fetuses in the uterus of CBA/J mice correlates with deficient non-T suppressor cell activity

    The mammalian fetus has been viewed as an unusually successful type of allograft and unexplained spontaneous abortion as a possible example of maternal rejection. Previous studies have shown the presence of small lymphocytic suppressor cells in the murine decidua which block the generation and reactivation of anti-paternal cytotoxic T lymphocytes (CTL) and lymphokine-activated killer cells (LAK) by elaborating a factor that inhibits the response to interleukin 2 (IL 2). A deficiency of these suppressor cells was associated with implants of xenogeneic Mus caroli embryos in the Mus musculus uterus which are infiltrated by maternal lymphoid cells and aborted. A deficiency of such suppressor cells in the lymph nodes draining the uterus of CBA/J females in the process of aborting their semi-allogeneic CBA x DBA/2 F 1 progeny has also been shown. CBA/J females possess significantly lower levels of decidua-associated non-T suppressor cells on day 8.5 to 10.5 of allopregnancy than do mothers that will produce large litters of live babies. The F 1 embryos are infiltrated by maternal lymphocytes prior to abortion, and the infiltration and abortion rate appears to be augmented by pre-immunization with paternal DBA/2 spleen cells. The CBA/J x DBA/2J mating combination provides a model of spontaneous abortion in which immunologic factors play an important role and demonstrates that the association between deficiency of decidua-associated suppressor cells and xenopregnancy failure also holds true for the failure of allopregnancies resulting from natural within-species mating

    Including support staff in practice change initiatives is a promising strategy to successfully implement new reproductive health services. The Resident Training Initiative in Miscarriage Management (RTI-MM) is an intervention designed to facilitate implementation of manual vacuum aspiration (MVA) for management of spontaneous abortion. The purpose of this study was to identify training program components that enhanced interprofessional training and provide lessons learned for engaging support staff in implementing uterine evacuation services. We conducted a secondary analysis of qualitative data to identify themes within three broad areas: interprofessional education, the role of support staff, and RTI-MM program components that facilitated support staff engagement in the process of implementing MVA services. We identified three key themes around interprofessional training and the role of support staff: "Training together is rare," "Support staff are crucial to practice change," and "Transparency, peers and champions." We present lessons learned that may be transferrable to other clinic sites: engage site leadership in a commitment to interprofessional training; engage support staff as teachers and learners and in shared values and building professionalism. This manuscript adds to what is known about how to employ interprofessional education and training to engage support staff in reproductive health services practice change initiatives. Lessons learned may provide guidance to clinical sites interested in interprofessional training, improving service delivery, or implementing new services. Copyright © 2013 Elsevier Inc.

    To assess the association of human leukocyte antigen DQ gene polymorphisms with unexplained recurrent spontaneous abortion (URSA) among ethnic Han Chinese from Wenzhou region. Fifty couples with URSA (URSA group) and 66 couples with normal pregnancy history (control group) were recruited. The alleles of HLA-DQA1 and HLA-DQB1 were analyzed by polymerase chain reaction with specific sequence primers (PCR-SSP) in all subjects. The frequency distribution of HLA-DQ alleles, odds ratios (OR) between each group and sharing of HLA-DQ alleles were calculated. The frequency distribution of HLA-DQB1*03:03 allele in the females with URSA was significantly higher than that healthy females (21.00% vs. 9.85%, OR=2.433, 95%CI: 1.232-4.894, χ(2)=5.657, PHLA-DQA1 alleles in couples with URSA was increased compared with the control group (70.27% vs. 44.64%, OR=2.931, 95%CI: 1.216-7.067, PHLA-DQA1 alleles may contribute to the susceptibility of URSA among ethnic Han Chinese from Wenzhou region. The allele of HLA-DQB1*03:03 in the females may be predisposing factor for URSA. However, the HLA-DQB1*05:02 allele in both gender and HLA-DQB1*05:03 allele in females may confer a protective effect.

    The establishment and maintenance of successful pregnancy mainly depends on trophoblast cells. Their dysfunction has been implicated in recurrent spontaneous abortion (RSA), a major complication of pregnancy. However, the underlying mechanisms of trophoblasts dysfunction remain unclear. DNA-damage-induced cell apoptosis has been reported to play a vital role in cell death. In this study, we identified a novel microRNA (miR-520) in RSA progression via regulating trophoblast cell apoptosis. Microarray analysis showed that miR-520 was highly expressed in villus of RSA patients. By using flow cytometry analysis, we observed miR-520 expression was correlated with human trophoblast cell apoptosis in vitro, along with decreased poly (ADP-ribose) polymerase-1 (PARP1) expression. With the analysis of clinic samples, we observed that miR-520 level was negatively correlated with PARP1 level in RSA villus. In addition, overexpression of PARP1 restored the miR-520-induced trophoblast cell apoptosis in vitro. The status of chromosome in trophoblast implied that miR-520-promoted DNA-damage-induced cell apoptosis to regulate RSA progression. These results indicated that the level of miR-520 might associate with RSA by prompting trophoblast cell apoptosis via PARP1 dependent DNA-damage pathway.

    Systemic monitoring of immune system may not precisely outline the local immune status in the uterus. This survey is a continuation of our previous studies on potential usefulness of menstrual blood (MB) immunophenotyping as a tool for investigation of immunological disturbances in pregnancy-related disorders. Peripheral blood (PB) and MB from healthy fertile (n = 15), unexplained recurrent spontaneous abortion (URSA; n = 15), and unexplained infertile women (n = 8) were collected simultaneously in the second day of their menstrual cycle and frequency of natural killer T (NKT)-like cell subpopulations were assessed by flow cytometry. Menstrual blood of all experimental groups contained higher percentage of TCRαβ + , CD45RO + , and CD16 - NKT-like cells compared to corresponding PB. Frequency of MB NKT-like cells in unexplained infertile participants was lower than fertile and URSA groups. Compared to normal participants, patients with URSA had lower frequency of PB TCRαβ + and higher CD16 + , while in infertile woman frequencies of PB CD45RO + , CD45RO - , CD16 - , IL17 + , and MB CD45RO + NKT-like cells were lower. Although, PB and MB seemingly have the same histological nature, our results showed that MB contained different composition of NKT-like subsets with different cytokine profiles and could be viewed as one potential biological sample for evaluation of patients with infertility and URSA.

    The current study was aimed to investigate the association of CLTA-4/Foxp3 polymorphisms and chromosomal abnormalities with recurrent spontaneous abortion (RSA) risk in a Chinese Han population. Altogether, 1284 RSA women and 1046 women with normal pregnancy were incorporated in this study. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was implemented to genotype the single-nucleotide polymorphisms (SNPs) located within CTLA4 and Foxp3. Moreover, the cytogenetic diagnosis was performed in line with the standards of G banding karyotype. As a consequence, rs231775 and rs3087243 of CTLA4, as well as rs2232365 and rs2232368 of Foxp3, all appeared to modify the risk of RSA. Besides, significant differences were found between the ratio of structural abnormality and that of numerical abnormality (P 3) than normal karyotypes. Of note, the synergic effects of the genotypes and chromosomal abnormality all tallied with the sub-multiplication model (OR chromosome  × OR SNP  > OR chromosome+SNP ), while rs2232365 GG and chromosomal aberration impacted the RSA risk in a super-multiplicative way that OR chromosome  × OR SNP  < OR chromosome+SNP . In conclusion, susceptibility to RSA was subject to the synthetic regulation of chromosomal aberrations and genetic mutations within CLTA-4 and Foxp3, suggesting that the conduction of karyotype analysis and genetic detection for RSA patients could effectively guide effective RSA counseling and sound child rearing.

    State of knowledge about misoprostol's use out of its marketing authorization during the first trimester of pregnancy, in early miscarriage or to induce abortion or medical termination of pregnancy. French and English publications were searched using PubMed, Cochrane Library and international learned societies recommendations. Cervical ripening prior to surgical uterine evacuation during the first trimester of pregnancy facilitates cervical dilatation and reduces operative time and uterine retention risk. Misoprostol, mifepristone and osmotic cervical dilators are equally efficient. Concerning first trimester miscarriage, surgical uterine evacuation remains the most effective and the quickest method of treatment (EL 1). Depending on the clinical situation, medical treatment using misoprostol (missed miscarriage) or expectative attitude (incomplete miscarriage) does not increase the risk of complications, neither haemorrhagic nor infectious (EL 1). However, these alternatives generally require longer outpatient follow-up, which leads to more consultations, prolonged bleeding and not planned surgical procedures (EL 1). Concerning missed miscarriage, a vaginal dose of 800 μg of misoprostol, possibly repeated 24 to 48 hours later, seems to offer the best efficiency/tolerance ratio (EL 2). Concerning early abortion, medical method is a safe and efficient alternative to surgery (EL 2). Success rates are inversely proportional to gestational age (EL 2). According to the modalities of its marketing authorization, 400 μg of misoprostol can only be given by oral route, for less than 7 weeks of amenorrhea (WA) pregnancies and after 36 to 48 hours following 600 mg of mifepristone (EL 1). However, 200mg of mifepristone is as efficient as 600 mg (EL 1). Beyond 7WA, misoprostol buccal dissolution (sublingual or prejugal) or vaginal administration are more efficient and better tolerated than oral ingestion (EL 1). Between 7 and 9WA, the best protocol in terms of efficiency and

    This study aims to determine whether periodontal conditions or dental health behaviors are risk factors for preterm birth (PTB), and whether periodontal pathogens are risk indicators for PTB among Korean mothers. This study was designed as a hospital-based case-control study. Examiner masking was ensured for the validity of the examinations. The mothers included those who gave birth between November 2007 and July 2009 at the obstetrics clinic of a general hospital in Seoul, Korea. Information on demographic and health conditions, periodontal conditions, and microbacterial data was collected. A total of 172 women met the inclusion criteria, 59 mothers who delivered a preterm neonate were assigned to the case group while the other 113 were assigned to the control group. There were no significant differences in demographic information, oral health conditions, and obstetric characteristics. Among health-related behaviors, only scaling within 12 months before pregnancy showed a significant difference (P = 0.031). Even in the adjusted logistic model, only the difference in the experience of scaling before pregnancy was significant between the PTB cases and the controls (P = 0.039). Periodontal disease did not exhibit a significant relationship with PTB even after adjustment for potential confounding factors. Among the microbacterial factors, only Porphyromonas gingivalis showed a slight difference (P = 0.060). There was a significant difference in scaling experience within 12 months before pregnancy and P. gingivalis showed a marginal difference between the PTB and the control groups but clinical periodontal conditions showed no association with PTB.

  18. An increase in vascular endothelial growth factor (VEGF and VEGF soluble receptor-1 (sFlt-1 are associated with early recurrent spontaneous abortion.

    Full Text Available Recurrent spontaneous abortion (RSA is a health problem that affects approximately 1% to 5% reproductive age woman. Yet, in around half of these patients, the mechanism for RSA is unexplained. Recent studies have indicated that placental ischemia/hypoxia and endothelial dysfunction are important factors in miscarriage. Other studies have indicated that the level and expression of soluble FMS-like tyrosine kinase-1 (sFlt1 is increased under a hypoxic environment. However, decreased sFlt-1 in the maternal circulation during the first trimester has recently been proposed as a potential marker for identifying risk of pregnancy loss. In this prospective study clinical samples were obtained within a short time after the fetal death, protein expression and maternal serum levels of sFlt1 were assessed and compared to samples taken from those with normal pregnancies. Our results indicate that levels of VEGF and sFlt-1 are both increased in women during early pregnancy compared women that are not pregnant (p<0.05 indicating that VEGF and sFlt-1 are both associated with pregnancy. More importantly, we detected a significant (p<0.05 increase in sFlt1 and VEGF levels and expression in the RSA patients who suffered subsequent miscarriages compare to controls. These results demonstrate that there is likely a relationship between VEGF, sFlt-1 and RSA suggesting that the high levels and over expression of sFlt-1 and VEGF might be associated with the pathogenesis of RSA.

    To perform a systematic review and meta-analysis to estimate the effect of endometriosis on preterm birth (PB) risk. Searches were conducted in PubMed-MEDLINE, Embase, Scopus, Web of Science, Cochrane Library, Google Scholar, and SciELO for studies published in all languages from inception through April 2017. We included cohort studies evaluating pregnant women with and without endometriosis and conception either by spontaneous conception (SC) or with assisted reproductive technology (ART). Primary outcome was PB (women with endometriosis, the PB risk was significantly increased in both SC (OR: 1.59; 95% CI: 1.32-1.90) and ART (OR: 1.43; 95% CI: 1.14-1.79). The SGA risk was increased in women with endometriosis (OR: 1.16; 95% CI: 1.05-1.28), while the IUGR and low birthweight risks and birthweight were not affected by endometriosis. Endometriosis is associated with increased PB risk in both SC and women who obtained pregnancy using ART. Prospective studies evaluating relevant outcomes are needed to confirm these results.

    As a psychoanalyst the author takes exception to a paper by Menne and Moersch entitled: "Psychoanalytical Experiences from the Supervision of Pregnancy Counseling," concerning the counseling of abortion applicants under West German Law No. 218. He disagrees with much of the psychoanalytical interpretations of women's desire for children and desire for abortion. Where the authors reason too much from the psychoanalytical viewpoint in the counseling situation this author accuses them of overlooking sociocritical arguments which find more elbow-room in the Law allowing "internal conflict" and "social counseling" as reasons for abortion. He accuses them of adhering too much to the letter of the law and urges them to resolve their not-so-easy task by helping the applicant achieve her desire for abortion as skillfully and responsibly as possible within the letter of that law.

    Inactivated influenza vaccine is recommended in any stage of pregnancy, but evidence of safety in early pregnancy is limited, including for vaccines containing A/H1N1pdm2009 (pH1N1) antigen. We sought to determine if receipt of vaccine containing pH1N1 was associated with spontaneous abortion (SAB). We conducted a case-control study over two influenza seasons (2010-11, 2011-12) in the Vaccine Safety Datalink. Cases had SAB and controls had live births or stillbirths and were matched on site, date of last menstrual period, and age. Of 919 potential cases identified using diagnosis codes, 485 were eligible and confirmed by medical record review. Exposure was defined as vaccination with inactivated influenza vaccine before the SAB date; the primary exposure window was the 1-28days before the SAB. The overall adjusted odds ratio (aOR) was 2.0 (95% CI, 1.1-3.6) for vaccine receipt in the 28-day exposure window; there was no association in other exposure windows. In season-specific analyses, the aOR in the 1-28days was 3.7 (95% CI 1.4-9.4) in 2010-11 and 1.4 (95% CI 0.6-3.3) in 2011-12. The association was modified by influenza vaccination in the prior season (post hoc analysis). Among women who received pH1N1-containing vaccine in the previous influenza season, the aOR in the 1-28days was 7.7 (95% CI 2.2-27.3); the aOR was 1.3 (95% CI 0.7-2.7) among women not vaccinated in the previous season. This effect modification was observed in each season. SAB was associated with influenza vaccination in the preceding 28days. The association was significant only among women vaccinated in the previous influenza season with pH1N1-containing vaccine. This study does not and cannot establish a causal relationship between repeated influenza vaccination and SAB, but further research is warranted. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To evaluate the role of cervical length (CL) and uterine artery pulsatility index (UtA-PI) at 11+0 to 13+6 weeks as predictors of spontaneous preterm delivery (sPTD) in a Chilean population. This was a prospective study of asymptomatic women with singleton pregnancies attending for a nuchal translucency scan at 11+0 to 13+6 weeks' gestation and who underwent a transvaginal scan for evaluation of CL and UtA-PI. Exclusion criteria were fetal and pregnancy complications (other than sPTD) and iatrogenic delivery atUtA-PI were adjusted for fetal crown-rump length and maternal characteristics and expressed as multiples of the median (MoM) of the unaffected group. Prediction of sPTD using maternal and pregnancy characteristics was studied using logistic regression analysis. A total of 3480 women were recruited into the study and, after application of exclusion criteria, 3310 were included in the analysis. The rate of sPTD atUtA-PI between pregnancies with and without subsequent sPTD. Logistic regression analysis showed that smoking and previous PTD were significantly associated with sPTD atUtA-PI nor CL during the first trimester was shown to be a useful predictor of early sPTD. However, a combined model that includes smoking and previous PTD predicts approximately one-quarter of those women destined to deliver at<34 weeks, with a false-positive rate of 8%.

    A large number of induced abortions exist in central Serbia, in spite of the fact that modern science made new methods and devices for the birth control available, which are more acceptable both from the medical and personal point of view. This fact shows contradictory situation and opens several questions. The crucial being: why do wome rely on abortion and do not use modern contraception? In research done in 1991--it refers to Belgrade and it includes four hundred women--confirmed was the accepted hypothesis that the extension of induced abortion developed from the discordance between comprehension of the need of birth control and the way it should be accomplished. The main causes of the discordance are insufficient knowledge about modern contraception, phychological barriers, insufficient cultural level (general, health, sex) of the population and lack of institutionalized contemporary concept fof family planning. Duration of prevalence of induced abortions indicates that underlying causes of frequency are numerous and stable over time. Considering this, and the slowness of any spontaneous change, it may be expected that the problem of abortions will be present in the years to come. However, duration of abortion prevalence will depend, to a large extent, on the ability and willingness of the State to cope with this issue.

    Introduction This study examined whether prenatal perceived stress levels during pregnancy were associated with preterm labor (PTL) or preterm birth (PTB). Methods Perceived stress levels were measured at 16 weeks gestation or less and between 20 and 24 weeks gestation in a sample of 1,069 low-income pregnant women attending Temple University prenatal care clinics. Scores were averaged to create a single measure of prenatal stress. PTB was defined as the occurrence of a spontaneous birth prior to 37 weeks gestation. PTL was defined as the occurrence of regular contractions between 20 and 37 weeks of pregnancy that were associated with changes in the cervix. Results Independent of potential confounding factors, prenatal perceived stress was not associated with PTL (OR 1.10; 95% CI 0.69-1.78, P = .66); however, prenatal stress trended toward an association with PTB (OR 1.49; 95% CI: 1.00-2.23, P =.05). The strongest predictor of preterm labor was a history of preterm labor in a prior pregnancy. Women with a history of PTL were two times more likely to experience PTL in the current pregnancy than women who did not have a PTL history (OR 2.16; 95% CI 1.05-4.41, P =.04). Historical risk factors of PTB, such as African American race, a history of abortion or a history of PTB were not related to PTL. The strongest predictor of PTB was having a history of PTB in a prior pregnancy (OR 2.55; 95% CI 1.54-4.24, P stress levels may be a risk factor for PTB independent of PTL; however, prenatal stress was not associated with PTL. Risk factors for PTL may be different from those of PTB. PMID:24890400

    Medical method of abortion (MMA) is a safe, efficient, and affordable method of abortion. However, incomplete abortion is a known side effect. To study incomplete abortion due to medication abortion and compare to spontaneous incomplete abortion and to study referral practices and prescriptions in cases of incomplete abortion following MMA. Prospective observational study of 100 women with first trimester incomplete abortion, divided into two groups (spontaneous or following MMA), was administered a questionnaire which included information regarding onset of bleeding, treatment received, use of medications for abortion, its prescription, and administration. Comparison of two groups was done using Fisher exact test (SPSS 21.0 software). Thirty percent of incomplete abortions were seen following MMA; possible reasons being self-administration or prescription by unregistered practitioners, lack of examination, incorrect dosage and drugs, and lack of follow-up. Complications such as collapse, blood requirement, and fever were significantly higher in these patients compared to spontaneous abortion group. The side effects of incomplete abortions following MMA can be avoided by the following standard guidelines. Self medication, over- the-counter use, and prescription by unregistered doctors should be discouraged and reported, and need of follow-up should be emphasized.

    Abortion is the termination of pregnancy prior to the 180th day, during which time the fetus is not yet viable outside the womb. Spontaneous abortion is the body's expulsion of a fetus during the 1st months of pregnancy. It is usually not very painful, does not involve much bleeding, and is rarely complicated by infection. Spontaneous abortion is much more frequent at the outset of pregnancy and may occur unnoticed. Its causes are unknown in over half of cases. The most important causes are developmental problems in the products of conception. Causes of spontaneous abortions of maternal etiology are most frequently uterine malposition or malformation. Serious illness in the mother is a less common cause of spontaneous abortion than once believed. Induced abortion is caused by the destruction of a normally implanted and healthy embryo. Its complications are related to the amount of bleeding or the introduction of germs from outside which can spread rapidly. Placental retention is a danger of all induced abortions. Induced abortion is common and in some countries it even creates demographic problems. Abortion is legal in many countries as an expression of the right to choose, but in others it is only legal on therapeutic grounds. Defenders and detractors of abortion have written extensively about it, with some works being sincere and some only tactical. The great majority of moralists are opposed to abortion, while biologists and scientists are divided on the question. The Spanish penal code punishes all persons who cause the death of a fetus or impede the process of gestation. The Catholic Church has considered abortion a homicide and against divine and natural laws. Legal or illegal, it is certain that the number of abortions increases each day. In the face of this reality, the need is for measures to avoid abortion whenever possible. Sex education in schools, full information on contraceptive methods and creation of family planning centers are some means of

    Objective This study was designed to characterize and compare the maternal and newborn epidemiological characteristics through analysis of environmental factors, socio-demographic characteristics, and clinical characteristics between the different clinical subtypes of preterm birth (PTB): Idiopathic (PTB-I), premature rupture of the membranes (PTB-PPROM) and medically indicated (PTB-M). The two subtypes PTB-I and PTB-PPROM grouped are called spontaneous preterm births (PTB-S). Methods A retrospective, observational study was conducted in 1.291 preterm non-malformed singleton live-born children to nulliparous and multiparous mother’s in Tucumán-Argentina between 2005 and 2010. Over 50 maternal variables and ten newborn variables were compared between the different clinical subtypes. The comparisons were done to identify heterogeneity between subtypes of preterm birth: (PTB-S) vs. (PTB-M), and within spontaneous subtype: (PTB-I) vs. (PTB-PPROM). In the same way, two conditional logistic multivariate regressions were used to compare the odds ratio (OR) between PTB-S and PTB-M, as well as PTB-I and PTB-PPROM. We matched for maternal age when comparing maternal variables and gestational age when comparing infant variables. Results The PTB-I subtype was characterized by younger mothers of lower socioeconomic status, PTB-PPROM was characterized by environmental factors resulting from inflammatory processes, and PTB-M was characterized by increased maternal or fetal risk pregnancies. Conclusions The main risk factor for PTB-I and PTB-M was having had a prior preterm delivery, however previous spontaneous abortion was not a risk factor, suggesting a reproductive selection mechanism.

    Abortion is common. Data on abortion rates are inexact but can be used to explore trends. Globally, the estimated rate in the period 2010-2014 was 35 abortions per 1000 women (aged 15-44 years), five points less than the rate of 40 for the period 1990-1994. Abortion laws vary around the world but are generally more restrictive in developing countries. Restrictive laws do not necessarily deter women from seeking abortion but often lead to unsafe practice with significant mortality and morbidity. While a legal framework for abortion is a prerequisite for availability, many laws, which are not evidence based, restrict availability and delay access. Abortion should be available in the interests of public health and any legal framework should be as permissive as possible in order to promote access. In the absence of legal access, harm reduction strategies are needed to reduce abortion-related mortality and morbidity. Abortion can be performed surgically (in the first trimester, by manual or electric vacuum aspiration) or with medication: both are safe and effective. Cervical priming facilitates surgery and reduces the risk of incomplete abortion. Diagnosis of incomplete abortion should be made on clinical grounds, not by ultrasound. Septic abortion is a common cause of maternal death almost always following unsafe abortion and thus largely preventable. While routine follow-up after abortion is unnecessary, all women should be offered a contraceptive method immediately after the abortion. This, together with improved education and other interventions, may succeed in reducing unintended pregnancy. © The Author 2017.

Late complications and sequelae may include chronic abdominal pain, menstrual disturbances, secondary sterility, or inability to have sexual relations because of vaginal lesions caused by caustic agents. Later pregnancies may be ectopic, or may spontaneously abort because of cervical lesions caused by trauma. Psychic sequelae may include depression or confusion. Information and contraceptive services should be made available to young girls to prevent illegal abortions. Social legislation should be modified to assist future mothers.

  16. Candidate gene analysis of spontaneous preterm delivery: New insights from re-analysis of a case-control study using case-parent triads and control-mother dyads

    Full Text Available Abstract Background Spontaneous preterm delivery (PTD has a multifactorial etiology with evidence of a genetic contribution to its pathogenesis. A number of candidate gene case-control studies have been performed on spontaneous PTD, but the results have been inconsistent, and do not fully assess the role of how two genotypes can impact outcome. To elucidate this latter point we re-analyzed data from a previously published case-control candidate gene study, using a case-parent triad design and a hybrid design combining case-parent triads and control-mother dyads. These methods offer a robust approach to genetic association studies for PTD compared to traditional case-control designs. Methods The study participants were obtained from the Norwegian Mother and Child Cohort Study (MoBa. A total of 196 case triads and 211 control dyads were selected for the analysis. A case-parent triad design as well as a hybrid design was used to analyze 1,326 SNPs from 159 candidate genes. We compared our results to those from a previous case-control study on the same samples. Haplotypes were analyzed using a sliding window of three SNPs and a pathway analysis was performed to gain biological insight into the pathophysiology of preterm delivery. Results The most consistent significant fetal gene across all analyses was COL5A2. The functionally similar COL5A1 was significant when combining fetal and maternal genotypes. PON1 was significant with analytical approaches for single locus association of fetal genes alone, but was possibly confounded by maternal effects. Focal adhesion (hsa04510, Cell Communication (hsa01430 and ECM receptor interaction (hsa04512 were the most constant significant pathways. Conclusion This study suggests a fetal association of COL5A2 and a combined fetal-maternal association of COL5A1 with spontaneous PTD. In addition, the pathway analysis implied interactions of genes affecting cell communication and extracellular matrix.

    Spontaneous preterm birth is a complex syndrome with multiple pathways interactions determining its occurrence, including genetic, immunological, physiologic, biochemical and environmental factors. Despite great worldwide efforts in preterm birth prevention, there are no recent effective therapeutic strategies able to decrease spontaneous preterm birth rates or their consequent neonatal morbidity/mortality. The Preterm SAMBA study will associate metabolomics technologies to identify clinical and metabolite predictors for preterm birth. These innovative and unbiased techniques might be a strategic key to advance spontaneous preterm birth prediction. Preterm SAMBA study consists of a discovery phase to identify biophysical and untargeted metabolomics from blood and hair samples associated with preterm birth, plus a validation phase to evaluate the performance of the predictive modelling. The first phase, a case-control study, will randomly select 100 women who had a spontaneous preterm birth (before 37 weeks) and 100 women who had term birth in the Cork Ireland and Auckland New Zealand cohorts within the SCOPE study, an international consortium aimed to identify potential metabolomic predictors using biophysical data and blood samples collected at 20 weeks of gestation. The validation phase will recruit 1150 Brazilian pregnant women from five participant centres and will collect blood and hair samples at 20 weeks of gestation to evaluate the performance of the algorithm model (sensitivity, specificity, predictive values and likelihood ratios) in predicting spontaneous preterm birth (before 34 weeks, with a secondary analysis of delivery before 37 weeks). The Preterm SAMBA study intends to step forward on preterm birth prediction using metabolomics techniques, and accurate protocols for sample collection among multi-ethnic populations. The use of metabolomics in medical science research is innovative and promises to provide solutions for disorders with multiple

    To evaluate the prevalence of spontaneous and induced abortion reported by a sample of Brazilian women interviewed in the National Demographic Health Survey of 1996. This was a secondary analysis of the Brazilian DHS-96 database, with information from interviews with a representative sample of 12,612 women about their reproductive life, focusing on the prevalence of spontaneous and induced abortion in the last five years and the associated factors for the various regions of the country and for Brazil as a whole. The sampling method was implemented with a strategy selection in two stages, one for the households and the other for women. The prevalence of spontaneous and induced abortion was estimated for Brazil and regions, and the socio-demographic characteristics of the women were analyzed as a function of the abortion's experience. A multinomial regression model analysis was used for the identification of factors independently associated with both types of abortion; their OR and respective 95% CI are reported. The prevalence of reported spontaneous abortion was 14% and the prevalence of induced abortion was 2.4% for the country as a whole. The state with the highest prevalence of induced abortion was Rio de Janeiro with 6.5%, followed by the Northeast region with 3.1%. The places with the lowest prevalence were the state of São Paulo and the South region. Both spontaneous and induced abortion showed higher prevalences with increasing age of the women studied. Being from the urban area (OR=1.5; 95%CI=1.0-2.3), having had more than one live child (OR=2.2; 95%CI=1.5-3.2) and being non-white (OR=1.4; 95%CI=1.0-1.8) were the main risk factors for induced abortion. The non-modifiable risk factors for induced abortion identified in this study indicate the need for improvement of educational and contraceptive actions, with priority for these specific demographic groups.

    Preterm birth is a complex disorder with a heritable genetic component. Studies of primarily White women born preterm show that they have an increased risk of subsequently delivering preterm. This risk of intergenerational preterm birth is poorly defined among Black women. Our objective was to evaluate and compare intergenerational preterm birth risk among non-Hispanic Black and non-Hispanic White mothers. This was a population-based retrospective cohort study, using the Virginia Intergenerational Linked Birth File. All non-Hispanic Black and non-Hispanic White mothers born in Virginia 1960 through 1996 who delivered their first live-born, nonanomalous, singleton infant ≥20 weeks from 2005 through 2009 were included. We assessed the overall gestational age distribution between non-Hispanic Black and White mothers born term and preterm (preterm (preterm birth, 34-36 weeks; and early preterm birth, preterm birth among all eligible births; and (2) suspected spontaneous preterm birth among births to women with medical complications (eg, diabetes, hypertension, preeclampsia and thus higher risk for a medically indicated preterm birth). Multivariable logistic regression was used to estimate odds of preterm birth and spontaneous preterm birth by maternal race and maternal gestational age after adjusting for confounders including maternal education, maternal age, smoking, drug/alcohol use, and infant gender. Of 173,822 deliveries captured in the intergenerational birth cohort, 71,676 (41.2%) women met inclusion criteria for this study. Of the entire cohort, 30.0% (n = 21,467) were non-Hispanic Black and 70.0% were non-Hispanic White mothers. Compared to non-Hispanic White mothers, non-Hispanic Black mothers were more likely to have been born late preterm (6.8% vs 3.7%) or early preterm (2.8 vs 1.0%), P preterm were not at an increased risk of early or late preterm delivery compared to non-Hispanic White mothers born term.

    A historical review of the legislation of abortion in America leads to the paramount 1973 amendment by the Supreme Court to legalize abortion. The 16 year old decision is currently up for reconsideration. As compared to the consensus of other countries who have similar policies, in the United States, the issue of abortion is still highly controversial. The Reagan era reflected an attitude of "anti-choice" that was further propagated by Reagan appointees. However, only 1 in 10 Americans believes abortion is murder as many are pro-choice. It is also observed that women who work outside the home are more likely to favor the right to choose an abortion than women who stay home. Compared to England and Wales, contraceptive measures are more limited and expensive in the U.S., and consequently, the overall ratio of abortions to live births is higher in the United States. As well, contraception remains elusive to the American teenager, and as a result, 80% of the 1.1 million teenage pregnancies are unwanted and 450,000 terminate their pregnancies. The final Supreme Court decision is expected at the end of June, and few expect a reversal of the 1973 decision. A possible decision may turn the authority to dictate the legal status of abortions back to the state. If this would happen, as with the situation of contraception, teenagers would be the hardest hit group and might be forced to seek illegal abortions or cross state lines.

  10. Predicting preterm birth: Cervical length and fetal fibronectin.

    2017-12-01

    Spontaneous preterm birth remains the leading cause of neonatal morbidity and mortality worldwide, and accounts for a significant global health burden. Several obstetric strategies to screen for spontaneous preterm delivery, such as cervical length and fetal fibronectin measurement, have emerged. However, the effectiveness of these strategies relies on their ability to accurately predict those pregnancies at increased risk for spontaneous preterm birth (SPTB). Transvaginal cervical shortening is predictive of preterm birth and when coupled with appropriate preterm birth prevention strategies, has been associated with reductions in SPTB in asymptomatic women with a singleton gestation. The use of qualitative fetal fibronectin may be useful in conjunction with cervical length assessment in women with acute preterm labor symptoms, but data supporting its clinical utility remain limited. As both cervical length and qualitative fetal fibronectin have limited capacity to predict preterm birth, further studies are needed to investigate other potential screening modalities.

    A six month prospective study on various aspects of abortion was conducted from April 1, 1991 to Sept. 30, 1991 in Sidamo Regional Hospital (Yirgalem). A total of 185 cases of abortion were seen. Of these, 64 (35%) were induced and 121 (65%) were spontaneous. There were 2 deaths in the illegally induced group abortion, 1 death in the other group. Induced abortion was higher in age group 20-24 (61%), single (65%), unemployed (70%), nulliparous (48%) and 7-12 grade educational level (67%). The pregnancy was unwanted in all cases of induced abortion and in 50 (41%) of the spontaneous cases. The common instruments used for inducing abortion were plastic catheters (58%) and metallic instruments (32%). The abortionists were mainly health workers (55%). The mean hospital stay was 6.3 days for illegally induced and 2.1 days for spontaneous abortions. The incidence of septic abortion was found to be statistically significantly higher in induced than in spontaneous abortion (p 0.05). The type of anaesthesia and required procedure are also analyzed in this study. Eighty-eight percent of the study population did not use any type of contraception. The role of contraception in preventing unwanted pregnancy and therefore induced abortion is discussed.

    Skewed male:female ratios at birth have been observed among certain immigrant groups. Data on abortion practices that might help to explain these findings are lacking. We examined 1 220 933 births to women with up to 3 consecutive singleton live births between 1993 and 2012 in Ontario. Records of live births, and induced and spontaneous abortions were linked to Canadian immigration records. We determined associations of male:female infant ratios with maternal birthplace, sex of the previous living sibling(s) and prior spontaneous or induced abortions. Male:female infant ratios did not appreciably depart from the normal range among Canadian-born women and most women born outside of Canada, irrespective of the sex of previous children or the characteristics of prior abortions. However, among infants of women who immigrated from India and had previously given birth to 2 girls, the overall male:female ratio was 1.96 (95% confidence interval [CI] 1.75-2.21) for the third live birth. The male:female infant ratio after 2 girls was 1.77 (95% CI 1.26-2.47) times higher if the current birth was preceded by 1 induced abortion, 2.38 (95% CI 1.44-3.94) times higher if preceded by 2 or more induced abortions and 3.88 (95% CI 2.02-7.50) times higher if the induced abortion was performed at 15 weeks or more gestation relative to no preceding abortion. Spontaneous abortions were not associated with male-biased sex ratios in subsequent births. High male:female ratios observed among infants born to women who immigrated from India are associated with induced abortions, especially in the second trimester of pregnancy. © 2016 Canadian Medical Association or its licensors.

    nonretentional endometritis. The condition should be treated with antibiotics and ice. Postoperative hemorrhage is unusual and is most frequently caused by retention. Psychological complications of abortion can be minimized by effective counseling. The counselor should seek to identify any history of psychological pathology or particularly stressful current situation. A certain amount of regret is a normal psychic response to abortion, but more serious symptoms such as suicidal thoughts or obvious depression may indicate the need for specialized care. Experience demonstrates that serious psychic reactions are rare and that a population at high risk can be defined. It includes very ambivalent women, those coerced into abortion, and those at the legal time limit. Women with a recent history of death or illness of a child, intrauterine death in the preceding pregnancy, or spontaneous abortions are also at risk.

    Polycystic ovary syndrome (PCOS) is a main cause of infertility, particularly in high-risk settings such as spontaneous abortions (SAB). We aimed to evaluate the effect of genetic polymorphisms in ACE and plasminogen activator inhibitor-1 (PAI-1) on the occurrence of SAB in PCOS. One hundred and forty-two PCOS patients (83 women have a history of one or more unexplained SAB, 59 women have successfully live births) and 107 healthy controls matched for age and body mass index were included in the study. Levels of PAI-1, LH, FSH, testosterone, fasting glucose and insulin were measured. ACE deletion (D)/insertion (I) and PAI-1 4G/5G gene polymorphisms were performed. The D/D and/or 4G/4G genotype frequency, the D or 4G allelic frequency, the combination of the ACE D/D and PAI-1 4G/5G, D/I and 4G/4G genotypes of PCOS patients with SAB women were statistically higher than non-SAB group (p4G/4G or D/D genotype of PCOS with SAB patients had significantly higher PAI-1 levels than non-SAB women. The ACE D/I and PAI-1 4G/5G gene polymorphisms might represent risk factor in PCOS with SAB. Homozygosity for ACE D or PAI-1 4G polymorphisms as well as compound carrier status are significant positive explanatory variable for PCOS patients with SAB, which may result in increased PAI-1 concentrations and hypofibrinolysis and contribute to early pregnancy loss.

    To assess whether women with a history of preterm birth, independent on the presence of prelabour rupture of the membranes (PROM) and growth deviation of the newborn, are more likely to develop preeclampsia with preterm or preterm birth in a subsequent pregnancy. We conducted a population-based cohort study, based on Medical Birth Registry of Norway between 1967 and 2012, including 742,980 women with singleton pregnancies who were followed up from their 1st to 2nd pregnancy. In the analyses we included 712,511 women after excluding 30,469 women with preeclampsia in the first pregnancy. After preterm birth without preeclampsia in the first pregnancy, the risk of preterm preeclampsia in the second pregnancy was 4-7 fold higher than after term birth (odds ratios 3.5; 95% confidence interval (CI) 3.0-4.0 to 6.5; 95% CI 5.1-8.2). The risk of term preeclampsia in the pregnancy following a preterm birth was 2-3 times higher than after term birth (odds ratios 1.6; 95% CI 1.5-1.8 to 2.6; 95% CI 2.0-3.4). After spontaneous non-PROM preterm birth and preterm PROM, the risk of preterm preeclampsia was 3.3-3.6 fold higher than after spontaneous term birth. Corresponding risks of term preeclampsia was 1.6-1.8 fold higher. No significant time trends were found in the effect of spontaneous preterm birth in the first pregnancy on preterm or term preeclampsia in the second pregnancy. The results suggest that preterm birth, regardless of the presence of PROM, and preeclampsia share pathophysiologic mechanisms. These mechanisms may cause preterm birth in one pregnancy and preeclampsia in a subsequent pregnancy in the same woman. The association was particularly evident with preterm preeclampsia.

    Randomized controlled trials (RCTs) have recently compared intramuscular 17α-hydroxyprogesterone caproate (17-OHPC) with vaginal progesterone for reducing the risk of spontaneous preterm birth (SPTB) in singleton gestations with prior SPTB. The aim of this systematic review and meta-analysis was to evaluate the efficacy of vaginal progesterone compared with 17-OHPC in prevention of SPTB in singleton gestations with prior SPTB. Searches of electronic databases were performed to identify all RCTs of asymptomatic singleton gestations with prior SPTB that were randomized to prophylactic treatment with either vaginal progesterone (intervention group) or intramuscular 17-OHPC (comparison group). No restrictions for language or geographic location were applied. The primary outcome was SPTB EMBARAZOS CON FETO ÚNICO: REVISIÓN SISTEMÁTICA Y METAANÁLISIS DE ENSAYOS CONTROLADOS ALEATORIOS: RESUMEN OBJETIVO: Recientemente se han realizado varios ensayos controlados aleatorios (ECA) que comparaban el caproato de 17α-hidroxiprogesterona (17-OHPC, por sus siglas en inglés) por vía intramuscular con la progesterona por vía vaginal para la reducción del riesgo de parto pretérmino espontáneo (PPTE) en embarazos con feto único de gestantes con historial de PPTE. El objetivo de esta revisión sistemática y metaanálisis fue evaluar la eficacia de la progesterona vaginal en comparación con la 17-OHPC en la prevención de embarazos con feto único de gestantes con historial de PPTE. MÉTODOS: Se realizaron búsquedas en bases de datos electrónicas para identificar todos los ECA con embarazos de feto único asintomáticos con historial de PPTE antes de ser asignados al azar a un tratamiento profiláctico, ya fuera con progesterona vaginal (grupo de intervención) o con 17-OHPC intramuscular (grupo de control).

    Full Text Available Abstract Background Corynebacterium aurimucosum is a slightly yellowish, non-lipophilic, facultative anaerobic member of the genus Corynebacterium and predominantly isolated from human clinical specimens. Unusual black-pigmented variants of C. aurimucosum (originally named as C. nigricans continue to be recovered from the female urogenital tract and they are associated with complications during pregnancy. C. aurimucosum ATCC 700975 (C. nigricans CN-1 was originally isolated from a vaginal swab of a 34-year-old woman who experienced a spontaneous abortion during month six of pregnancy. For a better understanding of the physiology and lifestyle of this potential urogenital pathogen, the complete genome sequence of C. aurimucosum ATCC 700975 was determined. Results Sequencing and assembly of the C. aurimucosum ATCC 700975 genome yielded a circular chromosome of 2,790,189 bp in size and the 29,037-bp plasmid pET44827. Specific gene sets associated with the central metabolism of C. aurimucosum apparently provide enhanced metabolic flexibility and adaptability in aerobic, anaerobic and low-pH environments, including gene clusters for the uptake and degradation of aromatic amines, L-histidine and L-tartrate as well as a gene region for the formation of selenocysteine and its incorporation into formate dehydrogenase. Plasmid pET44827 codes for a non-ribosomal peptide synthetase that plays the pivotal role in the synthesis of the characteristic black pigment of C. aurimucosum ATCC 700975. Conclusions The data obtained by the genome project suggest that C. aurimucosum could be both a resident of the human gut and possibly a pathogen in the female genital tract causing complications during pregnancy. Since hitherto all black-pigmented C. aurimucosum strains have been recovered from female genital source, biosynthesis of the pigment is apparently required for colonization by protecting the bacterial cells against the high hydrogen peroxide concentration in

    Preterm birth is the leading cause of perinatal morbidity and mortality worldwide, and is the most important challenge to modern obstetrics. A major obstacle has been that preterm birth is treated (implicitly or explicitly) as a single condition. Two-thirds of preterm births occur after the spontaneous onset of labor, and the remaining one-third after “indicated” preterm birth; however, the causes of spontaneous preterm labor and “indicated” preterm birth are different. Spontaneous preterm birth is a syndrome caused by multiple etiologies, one of which is a decline in progesterone action, which induces cervical ripening. A sonographic short cervix (identified in the midtrimester) is a powerful predictor of spontaneous preterm delivery. Randomized clinical trials and individual patient meta-analyses have shown that vaginal progesterone reduces the rate of preterm delivery at cervix, and therefore, the compound of choice is natural progesterone (not the synthetic progestin). Routine assessment of the risk of preterm birth with cervical ultrasound coupled with vaginal progesterone for women with a short cervix is cost-effective, and implementation of such a policy is urgently needed. Vaginal progesterone is as effective as cervical cerclage in reducing the rate of preterm delivery in women with a singleton gestation, history of preterm birth, and a short cervix (<25mm).

    Over six million induced abortions were reported in Africa in 2008 with over two million induced abortions occurring in Eastern Africa. Although a significant proportion of women in the region procure more than one abortion during their reproductive period, there is a dearth of research on factors associated with repeat abortion. Data for this study come from the Magnitude and Incidence of Unsafe Abortion Study conducted by the African Population and Health Research Center in Kenya in 2012. The study used a nationally-representative sample of 350 facilities (level II to level VI) that offer post-abortion services for complications following induced and spontaneous abortions. A prospective morbidity survey tool was used by health providers in 328 facilities to collect information on socio-demographic charateristics, reproductive health history and contraceptive use at conception for all patients presenting for post-abortion services. Our analysis is based on data recorded on 769 women who were classified as having had an induced abortion. About 16 % of women seeking post abortion services for an induced abortion reported to have had a previous induced abortion. Being separated or divorced or widowed, having no education, having unwanted pregnancy, having 1-2 prior births and using traditional methods of contraception were associated with a higher likelihood of a repeat induced abortion. The findings point to the need to address the reasons why women with first time induced abortion do not have the necessary information to prevent unintended pregnancies and further induced abortions. Possible explanations linked to the quality of post-abortion family planning and coverage of long-acting methods should be explored.

    We aimed to determine whether current contraceptive use is affected by a history of abortion for women from a country with abortion-restricted laws. This is an analysis of 2006 Brazil Demographic and Health Survey. Nonpregnant women whose first pregnancy occurred in the previous 5 years were selected for this study (n = 2,181). We used propensity score matching to compare current contraceptive use among women with induced or spontaneous abortion and women with no abortion. We found differences in the use, but women with a history of abortion did not report more effective contraceptive than women with no abortion, as we expected.

    To evaluate the reported occurrence of spontaneous and induced abortion, and abortion-associated severe maternal morbidity in Brazil. A secondary analysis of the 2006 Brazilian Demographic Health Survey was conducted. Interview data on women's experience of spontaneous/induced abortion and associated factors were analyzed overall and by geographic region. Multinomial logistic regression was performed to identify factors independently associated with abortion. The risk of associated severe maternal morbidity was estimated. The reported lifetime rates of spontaneous and induced abortion were 13.3% and 2.3%, respectively, and were highest in the north (4.3%) and northeast (3.5%). The rate of spontaneous abortion was higher among women aged 40-49 years (odds ratio [OR] 1.15; 95% confidence interval [CI], 1.03-1.30) and among those with 0 or 1 children or delivery (OR 1.97; 95% CI, 1.36-2.85 vs OR 1.98; 95% CI, 1.37-2.86). Induced abortion was not associated with sociodemographic factors. Abortion significantly increased the risk of complications (hemorrhage and infection). Spontaneous abortion was significantly associated with parity and maternal age. Abortion in general carried a higher risk of severe maternal complications.

    Worldwide, 13% of maternal deaths are caused by complications of spontaneous or induced abortion, 29% in Uruguay and nearly half (48%) in the Pereira Rossell Hospital. This paper describes a risk reduction strategy for unsafe abortions in Montevideo, Uruguay, where over one-fourth of maternal deaths are caused by unsafe abortion. Although abortion is not legal in Uruguay, women desiring abortions can be counseled before and immediately after to reduce the risk of injury. Women contemplating abortion were invited to attend a "before-abortion" and an "after-abortion" visit at a reproductive health polyclinic. At the "before-abortion" visit, gestational age, condition of the fetus and pathologies were diagnosed and the risks associated with the use of different abortion methods (based on the best available scientific evidence) were described. The "after-abortion" visit allowed for checking for possible complications and offering contraception. From March 2004 through June 2005, 675 women attended the "before-abortion" and 495 the "after-abortion" visit, the number increasing over time. Some women (3.5%) decided not to abort, others were either not pregnant, the fetus/embryo was dead or the woman had a condition that permitted legal termination of pregnancy in the hospital (7.5%). Most women, however, aborted. All women used vaginal misoprostol in the doses recommended in the medical literature. There were no serious complications (one mild infection and two hemorrhages not requiring transfusion). The strategy is effective in reducing unsafe abortions and their health consequences.

    Are women with asthma, and more specifically those with severe or uncontrolled asthma, at higher risk of spontaneous and induced abortions? Pregnant women with asthma, notably when uncontrolled, are at higher risk of spontaneous abortion. Only one study has examined the association between asthma and spontaneous and induced abortions and revealed a modest increase in the risk of spontaneous abortions, particularly in women with more severe asthma and those with previous exacerbations, and a marginal decrease in the risk of induced abortions. A cohort of pregnancies from asthmatic (n = 15,107) and non-asthmatic (n = 34,331) women was reconstructed by linking three administrative databases from Quebec (Canada), between 1992 and 2002. The cohort included 7870 spontaneous abortions, 14,596 induced abortions and 26,972 live births. Pregnant women with and without asthma were analyzed. Asthma was defined by at least one asthma diagnosis and one dispensed prescription for an asthma medication in the 2 years prior to or during pregnancy. Asthma severity and control were assessed using validated indexes in the year before the 20th week of pregnancy or the termination of the pregnancy. Logistic polytomous regression models were used to estimate the relationship between asthma and asthma severity and control on the risk of abortion, while adjusting for potential confounders. The prevalence of spontaneous and induced abortions was 15.9 and 29.5%, respectively. Maternal asthma was associated with an increased risk of a spontaneous abortion [odds ratio (OR) = 1.41; 95% confidence interval (CI): 1.33-1.49] and a decreased risk of induced abortions (OR = 0.92; 0.88-0.97). No association was observed between asthma severity and abortion, while uncontrolled asthma increased the risk of a spontaneous abortion by 26% (95% CI: 14-41%) and the risk of induced abortions by 11% (95% CI: 1-21%). It is possible that the study results were confounded by imbalances between groups in variables

    To compare and confirm the impact of prepregnancy body mass index on pregnancy outcome in women with a singleton conceived by assisted reproductive technology and spontaneously conceived pregnancy. A sample of 165 and 247 pregnant women with and without assisted reproductive technology were retrospectively recruited from electronic medical charts of C hospital. There were significant differences between the two groups for maternal age, paternal age, length of marriage, prepregnancy body mass index, parity, spontaneous abortion experience, and preterm delivery. A prepregnancy body mass index of ≥25 was associated with higher risk for maternal and neonatal complication in the assisted reproductive technology group. The results indicate that a higher prepregnancy body mass index is associated with increased risks for adverse pregnancy outcomes for women using assisted reproductive technology. So these women need appropriate care to compensate for the risk.

    Full Text Available In a historical cohort study we evaluated the effects of spontaneous abortion on subsequent pregnancy outcome. 1693 pregnant women were classifield in three groups: 1100: without any prior pregnancy, group 1; 550: with history of one spontaneous abortion (G2A1, group 2; 43: with two or more prior spontaneous abortions and no other prior pregnancies, group 3. We collected data through interview, patient's records and physical examination. We matched the patients according to their age subgroups, history of chronic disease, drug administration and radiation during current pregnancy and familial marriage. Then we compared adverse outcome of present pregnancy in group 1 and 2 with the women without prior pregnancy. We analysed the data with Chi-square and Fisher's exact methods. In this study we concluded that history of one spontaneous abortion had no effect on subsequent pregnancy except on prolonged ROM (P<0.000, but history of two or more abortions significantly affects occurrence of stillbirth (RR=29, P=0.003 and placenta previa (RR=8.5, P=0.03. These findings suggest that pregnant women with history of two or more spontaneous abortion need special prenatal care.

    2009-12-01

    We describe five pitfalls of medical abortion: ectopic pregnancy not terminated after misoprostol, but without negative side-effects; long-term vaginal blood loss with suspicious retained products which disappeared spontaneously; a patient with uterus myomatatosus with severe pain and retained products in the uterus; repetition of misoprostol because of retained products in the uterus after two weeks and an allergic reaction to methotrexate. Despite these pitfalls, there are enough benefits to consider medical abortion with methotrexate and misoprostol as a safe method with a high success rate of more than 91% and a good alternative for surgical abortion. An invasive procedure is not necessary, there are no long-term complications and it can be performed at an earlier stage, which makes it more acceptable in society. In Curaçao, where abortion is legally restricted, medical abortion is performed with methotrexate and misoprostol. In countries where abortion is legal, mifepristone and misoprostol are the first choice.

    To determine whether sonographically measured cervical length is an effective predictive tool in women with threatened preterm labor and a history of past spontaneous preterm delivery. This was a retrospective cohort study of all women with singleton pregnancies who presented with preterm labor at less than 34 + 0 weeks' gestation and underwent sonographic measurement of cervical length in a tertiary medical center between 2007 and 2012. The accuracy of cervical length in predicting preterm delivery was compared between women with and those without a history of spontaneous preterm delivery. Women with risk factors for preterm delivery other than a history of preterm delivery were excluded from both groups. Overall, 1023 women who presented with preterm labor met the study criteria, of whom 136 (13.3%) had a history of preterm delivery (past-PTD group) and 887 (86.7%) had no risk factors for preterm delivery (low-risk group). The rate of preterm delivery was significantly higher for women with a history of preterm delivery (36.8% vs 22.5%; P delivery interval in low-risk women (r = 0.32, P delivery (r = 0.07, P = 0.4). On multivariable analysis, cervical length was independently associated with the risk of preterm delivery for women in the low-risk group but not for women with a history of previous preterm delivery. For women with previous preterm delivery who presented with threatened preterm labor, cervical length failed to distinguish between those who did and those who did not deliver prematurely (area under the receiver-operating characteristics curve range, 0.475-0.506). When using standardized thresholds, the sensitivity and specificity of cervical length for the prediction of preterm delivery were significantly lower in women with previous preterm delivery than in women with no risk factors for preterm delivery. Cervical length appears to be of limited value in the prediction of preterm delivery among women with threatened preterm labor

    Analysis of abortion in Mexico from a juridical perspective requires recognition that Mexico as a national community participates in a double system of values. Politically it is defined as a liberal, democratic, and secular state, but culturally the Judeo-Christian ideology is dominant in all social strata. This duality complicates all juridical-penal decisions regarding abortion. Public opinion on abortion is influenced on the 1 hand by extremely conservative groups who condemn abortion as homicide, and on the other hand by groups who demand legislative reform in congruence with characteristics that define the state: an attitude of tolerance toward the different ideological-moral positions that coexist in the country. The discussion concerns the rights of women to voluntary maternity, protection of health, and to making their own decisions regarding their bodies vs. the rights of the fetus to life. The type of analysis is not objective, and conclusions depend on the ideology of the analyst. Other elements must be examined for an objective consideration of the social problem of abortion. For example, aspects related to maternal morbidity and mortality and the demographic, economic, and physical and mental health of the population would all seem to support the democratic juridical doctrine that sees the clandestine nature of abortion as the principal problem. It is also observed that the illegality of abortion does not guarantee its elimination. Desperate women will seek abortion under any circumstances. The illegality of abortion also impedes health and educational policies that would lower abortion mortality. There are various problems from a strictly juridical perspective. A correct definition of the term abortion is needed that would coincide with the medical definition. The discussion must be clearly centered on the protected juridical right and the definition of reproductive and health rights and rights to their own bodies of women. The experiences of other

    Globally, about 11% of all liveborn infants are preterm. To date, data on prevalence and risk factors of preterm birth (PTB) in Russia are limited. The aims of this study were to estimate the prevalence of PTB in Murmansk County, Northwestern Russia and to investigate associations between PTB and selected maternal factors using the Murmansk County Birth Registry. We conducted a registry-based study of 52 806 births (2006-2011). In total, 51 156 births were included in the prevalence analysis, of which 3546 were PTBs. Odds ratios with 95% confidence intervals of moderate-to-late PTB, very PTB and extremely PTB for a range of maternal characteristics were estimated using multinomial logistic regression, adjusting for potential confounders. The overall prevalence of PTB in Murmansk County was 6.9%. Unmarried status, prior PTBs, spontaneous and induced abortions were strongly associated with PTB at any gestational age. Maternal low educational level increased the risk of extremely and moderate-to-late PTB. Young (Murmansk County, Russia was comparable with data on live PTB from European countries. Adverse prior pregnancy outcomes, maternal low educational level, unmarried status, alcohol abuse, and diabetes mellitus or gestational diabetes were the most common risk factors for PTB. © 2016 John Wiley & Sons Ltd.

    To explore the association between maternal abortion history and congenital heart defect (CHD) risk in subsequent pregnancies. A multihospital-based case-control study was conducted. The cases included 370 women whose fetuses were diagnosed with CHDs. The controls were 413 women with fetuses without an apparent malformation in the same hospital. All of the participants were investigated by trained interviewers. Univariate analysis was performed, followed by multivariate logistic regression analysis to calculate odds ratio and 95% confidence interval to evaluate the risk of maternal abortion history on CHD risk. There were no statistically significant positive associations between maternal abortion (induced abortion and spontaneous abortion) occurrence and the risk of CHDs. There were no statistically significant positive associations between the number of maternal abortions (induced and spontaneous) and the risk of congenital heart defects. Maternal abortion history may not be associated with fetal CHDs.

    Induced abortion has been legal in India on a broad range of medical and social grounds since 1980s. Often, induced abortion is resorted to as a means for contraception, and has a potential to be misused for sex selective feticide. We assessed the rates, trends, causes and determinants of induced abortions from 2008-12 in a rural community of northern India. Present study is a secondary data analysis of pregnancy outcomes at Ballabgarh Health and Demographic Surveillance System from 2008-12. The data was retrieved from the Health and Management Information System maintained at Ballabgarh. Cause of abortion was self-reported by the women who underwent abortion. Of the 11,102 pregnancies, 1,226 (11%) culminated as abortions of which 425 (3.8%) were induced abortions. Spontaneous abortion rate (7.2%) was twice that of induced abortion rate (3.8%). Both abortion rates had an increasing trend during the course of the study period. Self-reported reasons for opting for induced abortions were bleeding per vaginum (23%), unwanted pregnancy (16%), and unviable fetus diagnosed by ultrasonography (11%). Eight percent of the induced abortions were due to the female sex of the fetus. About 11% of the abortions were performed beyond 20 weeks of gestation which was the upper legal permissible gestational age for performing induced abortions in India. About 10% of the abortions were performed by unqualified practitioners. Caste, wealth index, birth order and size of the village population were the factors that were significantly associated with induced abortion. Though the abortion rate was low, the proportionate contribution of induced abortion was more than what could be expected. Unsafe and sex selective abortion, though illegal, was prevalent. Upper caste and higher socio-economic status families were more likely to opt for induced abortion.

    Abortion stigma is widely acknowledged in many countries, but poorly theorised. Although media accounts often evoke abortion stigma as a universal social fact, we suggest that the social production of abortion stigma is profoundly local. Abortion stigma is neither natural nor 'essential' and relies upon power disparities and inequalities for its formation. In this paper, we identify social and political processes that favour the emergence, perpetuation and normalisation of abortion stigma. We hypothesise that abortion transgresses three cherished 'feminine' ideals: perpetual fecundity; the inevitability of motherhood; and instinctive nurturing. We offer examples of how abortion stigma is generated through popular and medical discourses, government and political structures, institutions, communities and via personal interactions. Finally, we propose a research agenda to reveal, measure and map the diverse manifestations of abortion stigma and its impact on women's health.

    Full Text Available Maternal mortality due to abortion complications stands among the three leading causes of maternal death in Botswana where there is a restrictive abortion law. This study aimed at assessing the patterns and determinants of post-abortion complications.A retrospective institution based cross-sectional study was conducted at four hospitals from January to August 2014. Data were extracted from patients' records with regards to their socio-demographic variables, abortion complications and length of hospital stay. Descriptive statistics and bivariate analysis were employed.A total of 619 patients' records were reviewed with a mean (SD age of 27.12 (5.97 years. The majority of abortions (95.5% were reported to be spontaneous and 3.9% of the abortions were induced by the patient. Two thirds of the patients were admitted as their first visit to the hospitals and one third were referrals from other health facilities. Two thirds of the patients were admitted as a result of incomplete abortion followed by inevitable abortion (16.8%. Offensive vaginal discharge (17.9%, tender uterus (11.3%, septic shock (3.9% and pelvic peritonitis (2.4% were among the physical findings recorded on admission. Clinically detectable anaemia evidenced by pallor was found to be the leading major complication in 193 (31.2% of the cases followed by hypovolemic and septic shock 65 (10.5%. There were a total of 9 abortion related deaths with a case fatality rate of 1.5%. Self-induced abortion and delayed uterine evacuation of more than six hours were found to have significant association with post-abortion complications (p-values of 0.018 and 0.035 respectively.Abortion related complications and deaths are high in our setting where abortion is illegal. Mechanisms need to be devised in the health facilities to evacuate the uterus in good time whenever it is indicated and to be equipped to handle the fatal complications. There is an indication for clinical audit on post-abortion care

    Preterm birth is the leading cause of neonatal morbidity and mortality in nonanomalous neonates in the United States. Women with a previous early spontaneous preterm birth are at highest risk for recurrence. Weekly intramuscular 17-alpha hydroxyprogesterone caproate reduces the risk of recurrent prematurity. Although current guidelines recommend 17-alpha hydroxyprogesterone caproate initiation between 16 and 20 weeks, in clinical practice, 17-alpha hydroxyprogesterone caproate is started across a spectrum of gestational ages. The objective of the study was to examine the relationship between the gestational age at 17-alpha hydroxyprogesterone caproate initiation and recurrent preterm birth among women with a prior spontaneous preterm birth 16-28 weeks' gestation. This was a retrospective cohort study of women from a single tertiary care center, 2005-2016. All women with ≥1 singleton preterm births because of a spontaneous onset of contractions, preterm prelabor rupture of membranes, or painless cervical dilation between 16 and 28 weeks followed by a subsequent singleton pregnancy treated with 17-alpha hydroxyprogesterone caproate were included. Women were grouped based on quartiles of gestational age of 17-alpha hydroxyprogesterone caproate initiation (quartile 1, 14 0/7 to 16 1/7 ; quartile 2, 16 2/7 to 17 0/7 ; quartile 3, 17 1/7 to 18 6/7 ; and quartile 4, 19 0/7 to 27 5/7 ). Women with a gestational age of 17-alpha hydroxyprogesterone caproate initiation in quartiles 1 and 2 were considered to have early-start 17-alpha hydroxyprogesterone caproate; those in quartiles 3 and 4 were considered to have late-start 17-alpha hydroxyprogesterone caproate.

    Full Text Available INTRODUCTION: Cerebral palsy ( CP is a group of permanent movement disorders that appear in early childhood. Preterm birth is the birth of baby before 37 completed weeks, a full term birth is birth at 37 to 42 weeks of gestation . AIM: To show the extent of association of preterm deliveries as a risk factor in development of cerebral palsy. MATERIALS AND METHODS: This r etrospective cohort study was conducted by eliciting history from the mothers of 99 cerebral palsy children who w ere treated in Rani Chandra Mani Devi Hospital, Visakhapatnam, Andhra Pradesh, India. De tailed history was taken from the mothers of 99 cerebral palsy children who were treated in this hospital. History regarding the period of gestation at which the child was born (preterm or full term, any previous history of pre - term delivery or abortions, was obtained from the mothers and the data analyzed . RESULTS: From this study it was observed the proportional association of pre - term births to cerebral palsy is 33 out 99 i.e., about 33.33%, Of these 33 cerebral palsy children highest association being with birth at 28 wks gestation (51 %. This study also shows th at the mothers with a previous history of preterm delivery have 14.4 times higher risk of subsequent pre term delivery; those with previous history of abortions have 5.7 times risk of pre - term delivery than mothers without such history. CONCLUSION: From th is study it was concluded that the pre - term birth plays a major role as a risk factor in the development of cerebral palsy with mothers having previous pre term delivery and previous abortions adding further to this risk.

  10. Trying to prevent abortion.

    It is known that, since antiquity, women confronted with an unwanted pregnancy have used abortion as a means of resolving their dilemma. Although undoubtedly widely used in all historical ages, abortion has come to be regarded as an event preferably avoided because of the impact on the women concerned as well as considerations for fetal life. Policies to reduce numbers and rates of abortion must acknowledge certain observations. Criminalization does not prevent abortion but increases maternal risks. A society's 'openness' in discussing sexual matters inversely correlates with abortion rates. Correlation between contraceptive use and abortion is also inverse but relates most closely to the efficacy of contraceptive methods used. 'Revolution' in the range of contraceptive methods used will have an equivalent impact on abortion rates. Secondary or emergency contraceptive methods have a considerable role to play in the reduction of abortion numbers. Good sex (and 'relationships') education programs may delay sexual debut, increase contraceptive usage and be associated with reduced abortion. Finally, interaction between socioeconomic factors and the choice between abortion and ongoing pregnancy are complex. Abortion is not necessarily chosen by those least able to support a child financially.

  11. [[Abortion: An Unforgivable Sin?].

    Science.gov (United States)

    Lalli, Chiara

    Abortion has become something to hide, something you can't tell other people, something you have to expiate forever. Besides, abortion is more and more difficult to achieve because of the raising average of consciencious objection (from 70 to 90% of health care providers are conscientious objectors, 2014 data, Ministero della Salute) and illegal abortion is "coming back"from the 70s, when abortion was a crime (Italian law n. 194/1978). Abortion is often blamed as a murder, an unforgivenable sin, even as genocide. Silence against shouting "killers!" to women who are going to have an abortion: this is a common actual scenario. Why is it so difficult to discuss and even to mention abortion?

    This review traces the discussion of abortion in the US through 10 of the best books published on the subject in the past 25 years. The first book considered is Daniel Callahan's "Abortion: Law, Choice and Morality," which was published in 1970. Next is book of essays also published in 1970: "The Morality of Abortion: Legal and Historical Perspectives," which was edited by John T. Noonan, Jr., who became a prominent opponent to the Roe decision. It is noted that Roman Catholics would find the essay by Bernard Haring especially interesting since Haring supported the Church's position on abortion but called for acceptance of contraception. Third on the list is historian James C. Mohr's review of "Abortion in America: The Origins and Evolution of National Policy," which was printed five years after the Roe decision. Selection four is "Enemies of Choice: The Right-to-Life Movement and Its Threat to Abortion" by Andrew Merton. This 1981 publication singled out a concern about sexuality as the overriding motivator for anti-abortion groups. Two years later, Beverly Wildung Harrison published a ground-breaking, feminist, moral analysis of abortion entitled "Our Right to Choose: Toward a New Ethic of Abortion. This was followed by a more empirical and sociopolitical feminist analysis in Kristin Luker's 1984 "Abortion and the Politics of Motherhood." The seventh book is by another feminist, Rosalind Pollack Petchesky, whose work "Abortion and Women's Choice: The State, Sexuality, and Reproductive Freedom" was first published in 1984 and reprinted in 1990. The eighth important book was "Abortion and Catholicism: The American Debate," edited by Thomas A. Shannon and Patricia Beattie Jung. Rounding out the list are the 1992 work "Life Itself: Abortion in the American Mind" by Roger Rosenblatt and Ronald Dworkin's 1993 "Life's Dominion: An Argument About Abortion, Euthanasia, and Individual Freedom."

    Our objective was to determine if transvaginal cervical length at 16-20 weeks is predictive of preterm birth preterm birth. Transvaginal cervical length was performed at 16-20-week gestation. The inclusion criteria were non-anomalous twins with transvaginal cervical length at 16-20 weeks. Receiver-operating characteristic (ROC) curves were generated to determine the transvaginal cervical length associated with preterm birth. Of 655 pregnancies, 27% (N = 178) women met our inclusion criteria. The rate of spontaneous preterm birth before 34 weeks was 16% (N = 29). A receiver operator characteristic curve was generated for all preterm birth preterm birth (n = 15) were excluded, the area under the curve was 0.59 (95% CI 0.47-0.70), indicating that transvaginal cervical length values were not a clinically useful test for the prediction of spontaneous preterm birth. A transvaginal cervical length of 30 mm from this model would produce a sensitivity of detecting spontaneous preterm birth of 95% and a specificity of 14%. In an asymptomatic twin population, a single transvaginal cervical length between 16 and 20 weeks was not predictive of spontaneous preterm birth before 34 weeks. Thus, our findings suggest that routine transvaginal cervical length screening of twins should not be performed between 16-20 weeks.

  14. Behavioral influences on preterm birth: a review.

    2010-05-01

    Epidemiologic studies of potential behavioral influences on preterm birth have proliferated and yet, with the exception of tobacco smoking, none can be considered an established cause. We conducted a comprehensive summary of the epidemiologic evidence on tobacco, alcohol, and illicit drug use, and physical, sexual, and occupational activity, to identify promising research directions, as well as research topics that are at an impasse based on currently available methods. Tobacco use is weakly but consistently associated with preterm birth-stronger for heavier smoking, and for spontaneous preterm birth and earlier preterm births. Weaker evidence suggests an adverse effect of environmental tobacco smoke, heavy alcohol or cocaine use, and physically strenuous work. Low levels of alcohol use, caffeine, sexual activity, and employment have generally not been found to be associated with preterm birth, and leisure-time physical activity has generated mixed results. Progress will require more detailed consideration of antecedents, new technologies for assessing exposure, and examination of biologic consequences of the behaviors of interest, focusing on pathways thought to mediate preterm delivery. New strategies-rather than more applications of the same approaches used in past studies-will move the research toward identifying causal relationships and, ultimately, may suggest preventive measures.

    Abortion is an extremely common procedure in the United States, with approximately 2% of women having an abortion before age 19 years. Although most pediatricians do not provide abortions, many will care for a young woman who is either considering an abortion or has already had one; therefore, the pediatrician should be able to provide accurate and appropriate counseling about this option. To provide the best care for adolescent patients considering abortion, pediatricians must be knowledgeable of aspects of abortion that are universal to all women and have an understanding of considerations specific to the adolescent patient. The purpose of this article is to (1) review recent statistics about teenagers and abortion, (2) explain the different types of abortion available to teenagers who desire to terminate an unwanted pregnancy, (3) discuss aspects of abortion unique to the adolescent population, such as insurance coverage and parental involvement laws, and (4) address common misconceptions about abortion.

    The author explores the possible relationship between psychopathology and abortion. The paper starts with the updating of epidemiological data regarding the incidence of abortion, especially in the current Spanish society. In this partnership there are three sections in the study of these possible relations between the abortion and the psychopathology: (a) in the new emerging sexual behaviour, especially among young people, and psychopathological factors possibly determining their sexual behaviour; (b) in the psychological and psychopathological context that makes the decision to abort, in regard to the factors of the couple and their families of origin and social context, and (c) in the frequent psychopathological disorders that seem to arise from the abortion, according to recent data reported by many researchers in the international scientific community. The study of the so-called Post-Abortion Syndrome (PAS) puts an end to this cooperation, distinguishing psychopathological profile characteristic that distinguishes the various stages of this syndrome.

    Preterm birth is the leading cause of neonatal death and handicap in survivors. Although twins are found in 1.5% of pregnancies they account for about 25% of preterm births. Randomized controlled trials in singleton pregnancies reported that the prophylactic use of progestogens, cervical cerclage and cervical pessary reduce significantly the rate of early preterm birth. In twin pregnancies, progestogens and cervical cerclage have been shown to be ineffective in reducing preterm birth. The objective of this study was to test the hypothesis that the insertion of a cervical pessary in twin pregnancies would reduce the rate of spontaneous early preterm birth. This was a multicenter, randomized controlled trial in unselected twin pregnancies of cervical pessary placement from 20(+0)-24(+6) weeks' gestation until elective removal or delivery vs. expectant management. Primary outcome was spontaneous birth control groups in rates of spontaneous birth birth. Copyright © 2016 Elsevier Inc. All rights reserved.

    Epidemiologic studies have suggested that abortion may cause long term health consequences such as cardiovascular disease. Until recently, studies focusing on the association between history of abortion and metabolic diseases were limited. In the present study, we aimed to investigate the association between history of abortion and metabolic syndrome (MetS) in middle-aged and elderly Chinese women. A cross-sectional survey was performed in 6302 women (age ≥ 40 years) in Shanghai. Standardized questionnaire was used to obtain the information about reproductive histories. Overall, we observed a positive association between history of induced abortion and the prevalence of MetS, independent of potential confounding factors. A multivariable-adjusted logistic regression analysis revealed that compared to those without a history of induced abortion, women with a history of induced abortion remained at 1.25 times more likely to have MetS (OR = 1.25, 95% CI = 1.06-1.47, P spontaneous abortion and the prevalence of MetS was observed. Compared to those without a history of spontaneous abortion, the multivariate-adjusted odds ratio associated with a history of spontaneous abortion for MetS was 0.88 (95% CI = 0.65-1.19, P > 0.05).

    The aim of the present study was to examine if certain aspects of a woman's experience of abortion might be associated with the risk of breast cancer. The case-control study was conducted in Kragujevac (Serbia) during the period 2004-2005. The case group (191 women) consisted of patients with newly diagnosed first primary breast cancer, which was histologically confirmed. The control group (191 women), individually matched by age (± 2 years), hospital admittance and place of residence (rural/urban) to the respective cases, was selected from female patients admitted for other diseases. The analysis was restricted to parous women (168 cases and 171 controls). Breast cancer risk was reduced among women who had a history of any abortion (adjusted OR, 0.46; 95% CI, 0.24-0.88). The protective effect was found for both induced abortion (adjusted OR, 0.47; 95% CI, 0.25-0.90) and spontaneous abortion (adjusted OR, 0.31; 95% CI, 0.10-0.98). It seems that these associations did not depend on the number of abortions, age at first abortion, or gestational age at first aborted pregnancy. Our study suggests that even short pregnancies ending in abortion add to the protection against breast cancer.

    Abstract Oral contraceptives (OCs) following induced abortion offer a reliable method to avoid repeated abortion. However, limited data exist supporting the effective use of OCs postabortion. We conducted this systematic review and meta-analysis in the present study reported immediate administration of OCs or combined OCs postabortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, increase endometrial thickness 2 to 3 weeks after abortion, and reduce the risk of complications and unintended pregnancies. A total of 8 major authorized Chinese and English databases were screened from January 1960 to November 2014. Randomized controlled trials in which patients had undergone medical or surgical abortions were included. Chinese studies that met the inclusion criteria were divided into 3 groups: administration of OC postmedical abortion (group I; n = 1712), administration of OC postsurgical abortion (group II; n = 8788), and administration of OC in combination with traditional Chinese medicine postsurgical abortion (group III; n = 19,707). In total, 119 of 6160 publications were included in this analysis. Significant difference was observed in group I for vaginal bleeding time (P = 0.0001), the amount of vaginal bleeding (P = 0.03), and menstruation recovery period (P abortion (P abortion, and reduce the risk of complications and unintended pregnancies.

    To find the latest and most accurate information on aspects of induced abortion. A literature survey was carried out in which five aspects of abortion were scrutinised: risk to life, risk of breast cancer, risk to mental health, risk to future fertility, and fetal pain. Abortion is clearly safer than childbirth. There is no evidence of an association between abortion and breast cancer. Women who have abortions are not at increased risk of mental health problems over and above women who deliver an unwanted pregnancy. There is no negative effect of abortion on a woman's subsequent fertility. It is not possible for a fetus to perceive pain before 24 weeks' gestation. Misinformation on abortion is widespread. Literature and websites are cited to demonstrate how data have been manipulated and misquoted or just ignored. Citation of non-peer reviewed articles is also common. Mandates insisting on provision of inaccurate information in some US State laws are presented. Attention is drawn to how women can be misled by Crisis Pregnancy Centres. There is extensive promulgation of misinformation on abortion by those who oppose abortion. Much of this misinformation is based on distorted interpretation of the scientific literature.

    Background Abortion was legalized in Nepal in 2002, following advocacy efforts highlighting high maternal mortality from unsafe abortion. We sought to assess whether legalization led to reductions in the most serious maternal health consequences of unsafe abortion. Methods We conducted retrospective medical chart review of all gynecological cases presenting at four large public referral hospitals in Nepal. For the years 2001–2010, all cases of spontaneous and induced abortion complications were identified, abstracted, and coded to classify cases of serious infection, injury, and systemic complications. We used segmented Poisson and ordinary logistic regression to test for trend and risks of serious complications for three time periods: before implementation (2001–2003), early implementation (2004–2006), and later implementation (2007–2010). Results 23,493 cases of abortion complications were identified. A significant downward trend in the proportion of serious infection, injury, and systemic complications was observed for the later implementation period, along with a decline in the risk of serious complications (OR 0.7, 95% CI 0.64, 0.85). Reductions in sepsis occurred sooner, during early implementation (OR 0.6, 95% CI 0.47, 0.75). Conclusion Over the study period, health care use and the population of reproductive aged women increased. Total fertility also declined by nearly half, despite relatively low contraceptive prevalence. Greater numbers of women likely obtained abortions and sought hospital care for complications following legalization, yet we observed a significant decline in the rate of serious abortion morbidity. The liberalization of abortion policy in Nepal has benefited women’s health, and likely contributes to falling maternal mortality in the country. The steepest decline was observed after expansion of the safe abortion program to include midlevel providers, second trimester training, and medication abortion, highlighting the importance

    Little is known about the costs and consequences of abortions to women and their households. Our aim was to study both costs and consequences of induced and spontaneous abortions and complications. We carried out a cross-sectional study between February and September 2012 in Ouagadougou, the capital city of Burkina Faso. Quantitative data of 305 women whose pregnancy ended with either an induced or a spontaneous abortion were prospectively collected on sociodemographic, asset ownership, medical and health expenditures including pre-referral costs following the patient's perspective. Descriptive analysis and regression analysis of costs were performed. We found that women with induced abortion were often single or never married, younger, more educated and had earlier pregnancies than women with spontaneous abortion. They also tended to be more often under parents' guardianship compared with women with spontaneous abortion. Women with induced abortion paid much more money to obtain abortion and treatment of the resulting complications compared with women with spontaneous abortion: US$89 (44 252 CFA ie franc of the African Financial Community) vs US$56 (27 668 CFA). The results also suggested that payments associated with induced abortion were catastrophic as they consumed 15% of the gross domestic product per capita. Additionally, 11-16% of total households appeared to have resorted to coping strategies in order to face costs. Both induced and spontaneous abortions may incur high expenses with short-term economic repercussions on households' poverty. Actions are needed in order to reduce the financial burden of abortion costs and promote an effective use of contraceptives.

    Little is known about the costs and consequences of abortions to women and their households. Our aim was to study both costs and consequences of induced and spontaneous abortions and complications. We carried out a cross-sectional study between February and September 2012 in Ouagadougou, the capital city of Burkina Faso. Quantitative data of 305 women whose pregnancy ended with either an induced or a spontaneous abortion were prospectively collected on sociodemographic, asset ownership, medical and health expenditures including pre-referral costs following the patient’s perspective. Descriptive analysis and regression analysis of costs were performed. We found that women with induced abortion were often single or never married, younger, more educated and had earlier pregnancies than women with spontaneous abortion. They also tended to be more often under parents’ guardianship compared with women with spontaneous abortion. Women with induced abortion paid much more money to obtain abortion and treatment of the resulting complications compared with women with spontaneous abortion: US$89 (44 252 CFA ie franc of the African Financial Community) vs US$56 (27 668 CFA).

    To determine the proportion of all clinically confirmed pregnancies that end as induced abortion in a cohort of pregnant women in Nigeria. A total of 490 women who attended prenatal clinics at the University of Benin Teaching Hospital were interviewed with the preceding birth technique (PBT) on the outcomes of their previous pregnancies, including abortions. Of the 490 women, 384 women (78.4%) reported previous abortions. A total of 1883 previous pregnancies were reported by the women, of which 914 ended in abortion, 545 in live births, and 421 in stillbirths, with 3 unclassified. The total abortion ratio was 914/1842 (49.6%), when 41 women who reported no previous pregnancies were excluded. Of the 914 abortions, 751 (82.25) were induced abortions, 146 (16.0%) were spontaneous abortions, 9 (0.98%) were missed abortions, and 8 were unclassified. Results of logistic regression analysis showed that women aged 25-29 years were 4 times more likely to report induced abortion compared with older women. Induced abortion was found to be highly prevalent in this region of Nigeria, according to self-reports of women who were asked questions on abortion in the context of medical care.

    The aim of this study was to assess whether serum markers would be useful as a new predictor of preterm birth in patients with spontaneous, late preterm labour. Patients diagnosed with late preterm labour were divided into preterm delivery (229 patients) and term delivery (178 patients) groups. The two groups were compared in terms of clinical characteristics and levels of serum markers (leukocyte subtypes, platelet, C-reactive protein [CRP], neutrophil to lymphocyte ratio [NLR] and platelet to lymphocyte ratio [PLR]), which were obtained at admission. The levels of leukocyte (p preterm delivery group, compared to the term delivery group. On multivariate regression analysis, NLR positive was the most powerful predictive variable (OR = 1.41; 95%CI: 1.32-1.51; p = .005). NLR had the highest area under curve (0.711; 95%CI 0.662-0.760) in predicting preterm birth and a NLR >6.2 had the highest sensitivity (65.1%) and specificity (62.5%). High NLR at admission is an independent predictor of preterm birth in patients with spontaneous, late preterm labour. Impact statement What is already known on this subject: Preterm birth accounts for 5-12% of all births, and is a major factor associated with perinatal morbidity and mortality worldwide. However, more than 70% of preterm births occur at late preterm between 34 0/7 and 36 6/7 weeks of gestation. The central role of systemic and subclinical infections in preterm labour is well documented. Intrauterine infection leading to delivery can be measured by using a variety of laboratory parameters. What do the results of this study add: Neutrophil to lymphocyte ratio is an inexpensive, easily interpretable and promising haematologic parameter that is widely available. This study explored the association of high neutrophil to lymphocyte ratio with the risk of preterm birth in women with preterm labour between 34 and 37 weeks of gestation. What are the implications of these findings for clinical practice and/or further

    Full Text Available INTRODUCTION: With the advent of assisted reproductive treatment options, the incidence of multiple pregnancies has increased. Although the need for elective single embryo transfer is emphasized time and again, its uniform applicability in practice is yet a distant goal. In view of the fact that triplet and higher order pregnancies are associated with significant fetomaternal complications, the fetal reduction is a commonly used option in such cases. This retrospective study aims to compare the perinatal outcome in patients with triplet gestation who have undergone spontaneous fetal reduction (SFR as against those in whom multifetal pregnancy reduction (MFPR was done. MATERIALS AND METHODS: In the present study, eighty patients with triplet gestation at 6 weeks were considered. The patients underwent SFR or MFPR at or before 12-13 weeks and were divided into two groups (34 and 46, respectively. RESULTS: Our study found no statistical difference in perinatal outcome between the SFR and MFPR groups in terms of average gestational age at delivery, abortion rate, preterm delivery rate, and birth weight. The study shows that the risk of aborting all fetuses after SFR is three times (odds ratio [OR] = 3.600, 95% confidence interval [CI] = 0.2794-46.388 that of MFPR in subsequent 2 weeks. There were more chances of loss of extra fetus in SFR (23.5% group than MFPR group (8.7% (OR = 3.889, 95% CI = 1.030-14.680. As neither group offers any significant benefit from preterm delivery, multiple pregnancies continue to be responsible for preterm delivery despite fetal reduction. CONCLUSION: There appears to be some advantages of MFPR in perinatal outcome when compared to SFR, especially if the latter happens at advanced gestation. Therefore, although it is advisable to wait for SFR to occur, in patients with triplet gestation at 11-12 weeks, MFPR is a viable option to be considered.

    Boundary work refers to the strategies deployed by professionals in the arenas of the public, the law and the workplace to define and defend jurisdictional authority. Little attention has been directed to the role of documents in negotiating professional claims. While boundary work over induced abortion has been extensively documented, few studies have examined jurisdictional disputes over the treatment of abortion complications, or post-abortion care (PAC). This study explores how medical providers deploy medical records in boundary work over the treatment of complications of spontaneous and induced abortion in Senegal, where induced abortion is prohibited under any circumstance. Findings are based on an institutional ethnography of Senegal’s national PAC program over a period of 13 months between 2010 and 2011. Data collection methods included in-depth interviews with 36 health care professionals, observation of PAC services at three hospitals, a review of abortion records at each hospital, and a case review of illegal abortions prosecuted by the state. Findings show that health providers produce a particular account of the type of abortion treated through a series of practices such as the patient interview and the clinical exam. Providers obscure induced abortion in medical documents in three ways: the use of terminology that does not differentiate between induced and spontaneous abortion in PAC registers, the omission of data on the type of abortion altogether in PAC registers, and reporting the total number but not the type of abortions treated in hospital data transmitted to state health authorities. The obscuration of suspected induced abortion in the record permits providers to circumvent police inquiry at the hospital. PAC has been implemented in nearly 50 countries worldwide. This study demonstrates the need for additional research on how medical professionals negotiate conflicting medical and legal obligations in the daily practice of treating abortion

    As of July 1991 abortion is still legal in Poland. Currently the Polish Parliament has taken a break from the debate because the issue is so important that any decision must not be made in past. There is strong pressure from the Catholic Church to eliminate access to abortion. In the fall the Polish people will vote for and elect their first truly democratic Parliament. Abortion does not seem to be playing as important a role as other political issues. In 1956 a law was passed that allowed a woman to have an abortion for medical or social reasons. This law resulted in allowing women in Poland to use abortion as their primary form of contraception. The vast majority of the abortions were performed under the social justification. Then, when democracy same to Poland with the help of the Catholic Church, an unprecedented debate in the mass media, churches, and educational institutions was stirred up. The government attempted to stay out of the debate at first. But as people from different side of the debate saw that they had an opportunity to influence things in their favor, they began to politicize the issue. Currently there are 4 different drafts of the new Polish abortion law. 3 of them radically condemn abortion while the 4th condemns it as a method of family planning, but allows to terminate pregnancies in order to save the life of the mother.

    The purpose of the study was to seek knowledge about the reasons for the very high rate of legal abortions in Greenland. In four municipalities in the Disko Bay region of West Greenland all pregnant women were asked to fill in a questionnaire. Due to organisational problems only 39% of the women were asked to participate and a total of 82 women seeking abortion and 175 women who wished to continue the pregnancy were enrolled in the study. A few Danish women (22) were subsequently removed from the study base. The women who wanted an abortion were more often than the other women single, their knowledge of Danish as a second language was poorer, and they less often had a job. Although the age distributions of the two groups were similar the women who wanted an abortion had more often been pregnant before (more births and more abortions). The women who wanted an abortion more often than the other women reported having been drunk, having had a pelvic inflammation or VD, and having been admitted to hospital. Half of the women who wanted an abortion reported that they had forgotten to use their contraception and one fourth were opposed to the use of contraception. There seems not to be a well defined high risk group for legal abortion but a general need for a more realistic view on contraception.

    Medical abortion with mifepristone and methotrexate regimens may be offered in a variety of American medical practice settings. In this article the new provider will find information on all aspects of the patient care delivery system for medical abortion, including physical space requirements, staffing and training, patient flow, cost, security, marketing, and quality assurance. Because of the limited published data available regarding logistic issues surrounding abortion care, the information in this article derives largely from the experiences of providers who have established medical abortion practices in their offices or clinics. Its goals are to help make the initial start-up phase briefer and more rewarding for new providers, to offer helpful guidelines for incorporation of medical abortion into practice, and to encourage more practitioners to see the benefits of adding this option to their practices.

    Counseling and education are correlated with women's satisfaction with all abortion care. They often assume a larger role in medical abortion because the patient is a more active participant in the abortion process. This article aims to enhance the practitioner's expertise in providing the information and care necessary for women considering early abortion with medical regimens. It offers general counseling guidelines and several likely clinical scenarios regarding the decision-making process, the screening of patients, and the initial and follow-up visits. Through effective communication, practitioners can provide the information and support that patients need to complete the abortion process safely and can help to strengthen women's confidence in managing their reproductive health experiences.

  3. Abortion: a history.

    1985-01-01

    This review of abortion history considers sacred and secular practice and traces abortion in the US, the legacy of the 19th century, and the change that occurred in the 20th century. Abortion has been practiced since ancient times, but its legality and availability have been threatened continuously by forces that would denigrate women's fundamental rights. Currently, while efforts to decrease the need for abortion through contraception and education continue, access to abortion remains crucial for the well-being of millions of women. That access will never be secure until profound changes occur in the whole society. Laws that prohibit absolutely the practice of abortion are a relatively recent development. In the early Roman Catholic church, abortion was permitted for male fetuses in the first 40 days of pregnancy and for female fetuses in the first 80-90 days. Not until 1588 did Pope Sixtus V declare all abortion murder, with excommunication as the punishment. Only 3 years later a new pope found the absolute sanction unworkable and again allowed early abortions. 300 years would pass before the Catholic church under Pius IX again declared all abortion murder. This standard, declared in 1869, remains the official position of the church, reaffirmed by the current pope. In 1920 the Soviet Union became the 1st modern state formally to legalize abortion. In the early period after the 1917 revolution, abortion was readily available in state operated facilities. These facilities were closed and abortion made illegal when it became clear that the Soviet Union would have to defend itself against Nazi Germany. After World War II women were encouraged to enter the labor force, and abortion once again became legal. The cases of the Catholic church and the Soviet Union illustrate the same point. Abortion legislation has never been in the hands of women. In the 20th century, state policy has been determined by the rhythms of economic and military expansion, the desire for cheap

    Preterm birth is a worldwide epidemic with a global incidence of 15 million per year. Though rates of preterm birth in the United States have declined over the last decade, nearly 1 in 10 babies is still born preterm. The incidence, gestational age, and underlying etiology of preterm birth is highly variable across different racial and ethnic groups and geographic boundaries. In this article, we review the epidemiology of preterm birth in the United States and globally, with a focus on temporal trends and racial, ethnic, and geographic disparities.

    1982-04-15

    Thomas W. Hilgers, M.D., testifying to the Australian Royal Commission on Human Relationships in 1975, alleged that liberal abortions laws in the U.S. caused more deaths among women of childbearing age than they prevented. This inference was subsequently challenged because his analysis used a misleading extrapolation of linear regression, applied information from 2 incomparable data sets, and selected unreasonable item intervals for comparisons. On October 14, 1981, Hilgers testified before the U.S. Senate Subcommittee on the Constitution. He stated that America's legal abortion policy has had no measurable beneficial effect on maternal deaths and also implied that "natural pregnancy" was safer than induced abortion. These inferences were based on his recent analysis of abortion mortality with the use of national data from 1940 to 1978. Exception is still taken with Hilgers' inferences for the following reasons: neglect of risk associated with the last half of pregnancy; use of provisional 1978 data; selection of inappropriate states and time intervals; absence of the most appropriate references; use of relative frequency rather than absolute numbers; and aggregation of abortion mortality with maternal mortality. Contrary to the statements by Hilgers, the availability of legal abortion has had a measurable impact on deaths among American women of reproductive age. In 1965, even before the availability of legal abortion, deaths of women from all types of abortion (legal, illegal, and spontaneous) began to decline more rapidly than deaths from other pregnancy related causes. In 1970 the decline of abortion mortality rapidly accelerated and generally continued through 1976. In sum, legalized abortion has had a definite impact on the health of American women of childbearing age who are faced with unwanted pregnancies.

    Full Text Available A case with bilateral spontaneous pneumothorax was presented. Etiology, mechanism, and treatment were discussed on the review of literature. Spontaneous Pneumothorax is a clinical entity resulting from a sudden non traumatic rupture of the lung. Biach reported in 1880 that 78% of 916 patients with spontaneous pneumothorax had tuberculosis. Kjergaard emphasized 1932 the primary importance of subpleural bleb disease. Currently the clinical spectrum of spontaneous pneumothorax seems to have entered a third era with the recognition of the interstitial lung disease and AIDS as a significant etiology. Standard treatment is including: observation, thoracocentesis, tube thoracostomy. Chemical pleurodesis, bullectomy or wedge resection of lung with pleural abrasion and occasionally pleurectomy. Little information has been reported regarding the efficacy of such treatment in spontaneous pneumothorax secondary to non bleb disease

    Cervical abortion is a spontaneous abortion of an intrauterine pregnancy into the cervical canal where the abortus is retained by a closed external os, causing distension of the cervical canal. Cervical abortion should be distinguished from the cervical pregnancy. We present a case of cervical abortion diagnosed preoperatively by transvaginal sonography and color doppler imaging, and treated by dilatation and curettage. Charateristic transvaginal sonographic findings and identification of subtrophoblastic blood flow by color doppler imaging could allow differentiation of the cevical aborition from the cervical pregnancy

    Gissi, Alessandra

    Perception of guilt and remorse is tied to the complicated question of what is an abortion. There is no doubt that abortion practices have had a long and complex history. Abortion is, in fact, a 'mobile' category, whose definition and identification depends on several factors and is related to the context and - not least - the complex question of identifying the actual voluntariness of the act. The frequency of spontaneous abortions, due to -excessive force or working conditions, and the inevitability of the appeal to the interruption of pregnancy in the absence of other means of fertility control methods, allowed a widespread lack of guilt, testified also by language even in the mid-twenties, when the fascist regime begins to structure a policy that culminates, during the thirties, in unprecedented emphasis on the role and the female body in an exclusively procreative function and configuration of maternity as a patriotic duty particularly enshrined in the new Penal code of 1930.

    2014-01-01

    Background While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated to be about 630 maternal deaths per 100,000 live births. Recent evidences have shown that a major factor in this trend is the high incidence of abortion in the country. The objective of this paper is, therefore, to investigate the factors determining the demand for abortion and post-abortion care in Ibadan city of Nigeria. Methods The study employed data from a hospital-based/exploratory survey carried out between March to September 2010. Closed ended questionnaires were administered to a sample of 384 women of reproductive age from three hospitals within the Ibadan metropolis in South West Nigeria. However, only 308 valid responses were received and analysed. A probit model was fitted to determine the socioeconomic factors that influence demand for abortion and post-abortion care. Results The results showed that 62% of respondents demanded for abortion while 52.3% of those that demanded for abortion received post-abortion care. The findings again showed that income was a significant determinant of abortion and post-abortion care demand. Women with higher income were more likely to demand abortion and post-abortion care. Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers’ education was only statistically significant in determining abortion demand but not post-abortion care demand. Conclusion The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this

A systematic review of the literature about post-abortion contraception was performed on Medline and Cochrane Database between 1978 and March 2016.

After an abortion, if the woman wishes to use a contraception, it should be started as soon as possible because of the very early ovulation resumption. The contraception choice must be done in accordance with the woman's expectations and lifestyle. The contraindications of each contraception must be respected. The long-acting reversible contraception, intra-uterine device (IUD) and implant, could be preferred (grade C) as the efficacy is not dependent on compliance. Thus, they could better prevent repeat abortion (LE3). In case of surgical abortion, IUD should be proposed and inserted immediately after the procedure (grade A), as well as the implant (grade B). In case of medical abortion, the implant can be inserted from the day of mifépristone, the IUD after an ultrasound examination confirming the success of the abortion (no continuing pregnancy or retained sac) (grade C).

    To evaluate the impact of a first trimester induced abortion on the risks of low birth weight (LBW) and preterm birth in a subsequent pregnancy we conducted a pregnancy-based cohort study in Shanghai, China with recruitment from 15 general hospitals (or maternity and infant health institutes) from...... singleton live births were analysed in this study. A total of 2953 pregnant women were enrolled and 2707 gave birth to live singletons. The overall incidence of LBW was 1·7%, 2·0% in the abortion cohort and 1·4% in the reference cohort. After controlling the potential confounders using logistic regression...... at recruitment, couples' occupation, education, age, infant sex, maternal body mass index at recruitment, contraceptive use and gestation age. Previous first trimester induced abortion did not significantly increase the risk of LBW or preterm birth. The study was performed in a low-risk population and results...

  17. Counselling pregnant women on abortions

    The author conducted a survey of one hundred women in Zadar seeking an abortion during the first trimester ofpregnancy. His purpose was to determine the women's motives for seeking abortions and evaluate their knowledge on abortion and the fetus. He found that the majority lacked a clear understanding of abortion techniques as well as fetal development. After an informative conversation, twelve of the women decided against having abortions. The author concluded that great ignorance, inhumane ...

    Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States. 2014. Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2014, data were received from 49 reporting areas. For trend analysis, abortion data were evaluated from 48 areas that reported data every year during 2005-2014. Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births). A total of 652,639 abortions were reported to CDC for 2014. Of these abortions, 98.4% were from the 48 reporting areas that provided data every year during 2005-2014. Among these 48 reporting areas, the abortion rate for 2014 was 12.1 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 186 abortions per 1,000 live births. From 2013 to 2014, the total number and rate of reported abortions decreased 2%, and the ratio decreased 7%. From 2005 to 2014, the total number, rate, and ratio of reported abortions decreased 21%, 22%, and 21%, respectively. In 2014, all three measures reached their lowest level for the entire period of analysis (2005-2014). In 2014 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2014, women aged 20-24 and 25-29 years accounted for 32.2% and 26.7% of all reported abortions, respectively, and had abortion rates of 21.3 and 18.4 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 17.1%, 9.7%, and 3.6% of all reported abortions

    Full Text Available Background: Preterm labor is a major cause of perinatal morbidity and mortality and it might be predicted by assessing the cervical change. Objective: To assess the association between absence of cervical gland area (CGA and spontaneous preterm labor (SPTL. Materials and Methods: This prospective cohort study was performed on 200 singleton pregnant women with a history of SPTL, second-trimester abortion in the previous pregnancy or lower abdominal pain in current pregnancy. Each patient underwent one transvaginal ultrasound examination between 14-28 wk of gestation. Cervical length was measured and CGA was identified and their relationship with SPTL before 35 and 37 wk gestation was evaluated using STATA software version 10. Results: The mean of cervical length was 36.5 mm (SD=8.4, the shortest measurement was 9 mm, and the longest one was 61 mm. Short cervical length (≤18mm was significantly associated with SPTL before 35 and 37 wk gestation. Cervical gland area (the hypoechogenic or echogenic area around the cervical canal was present in 189 (94.5% patients. Absent of CGA had a significant relationship with SPTL before 35 and 37 wk gestation (p=0.01 and p<0.001, respectively. Cervical length was shorter in women with absent CGA in comparison with subjects with present CGA: 37±10 mm in CGA present group and 23±9 mm in CGA absent group (p<0.001. Conclusion: Our study showed that cervical gland area might be an important predictor of SPTL which should be confirmed with further researches.

  20. Abortion and sterilization.

    Steele, S J

    1970-01-01

    This discusses activities current in England under the abortion law of April 1968. In England and Wales in 1969 there were 54,013 recorded abortions and 15 related deaths. Since then both the number of deaths and the number of abortions have been increasing. This abortion increase is partly attributed to the adverse publicity regarding the pill which has caused many women to give up oral contraceptives. Complications have included incomplete removal of the products of conception, sepsis, hemorrhage, and perforation of the uterus. There have been wide variation in interpretations of the law by different hospitals and staffs. Sterilization operations are being done in increasing number for both men and women. Carefully worded consent forms are now in use to insure patient understanding and consent. Psychological changes may follow sterilization, but are relatively uncommon. Physicians should do all possible to help women avoid unwanted pregnancies and thereby reduce the demand for termination.

    The prevalence of domestic violence and abortion in India is high, yet little is known about the relationship between these experiences. Data from two linked data sets, India's 1998-1999 National Family Health Survey (NFHS-2) and a follow-up survey in 2002-2003, were analyzed. The analysis examines how the experience of physical violence affects the subsequent uptake of abortion, and how the experience of abortion affects subsequent experience of physical, sexual, and verbal violence. Women who experienced physical violence have significantly higher odds of reporting a subsequent induced abortion, whereas women who had an induced abortion have significantly higher odds of reporting subsequent sexual and verbal violence. There was no significant relationship between domestic violence and spontaneous abortion. © The Author(s) 2016.

  2. Abortion and regret.

    Science.gov (United States)

    Greasley, Kate

    2012-12-01

    The article considers three theses about postabortion regret which seek to illustrate its pertinence to reasoning about abortion, and which are often deployed, either explicitly or implicitly, to dissuade women out of that reproductive choice. The first is that postabortion regret renders an abortion morally unjustified. The second is that that a relatively high incidence of postabortion regret-compared with a lower incidence of postnatal regret in the relevant comparator field-is good evidence for the moral impermissibility of abortion choice. The third is that high rates of postabortion regret suggest that abortion is not the most prudent or welfare-maximising choice for the woman concerned. All three theses argue for the compellingness of knowledge about postabortion regret in moral and practical reasoning about abortion, especially from the pregnant woman's point of view. This article argues that all three theses are flawed. In particular, it seeks to remind readers that feelings of regret directed at past decisions are often decoupled from the fact of the matter about their moral or rational justification. Moreover, certain features of reproductive decisions in particular make regret an especially unsuitable yardstick for actual justification in this context, and even less epistemically reliable as evidence for a lack of justification than it may be in other fields of decision-making. The implication is that rates of postabortion regret, even if they can be presumed to be higher than rates of postnatal regret, are not as pertinent to moral and practical reasoning about abortion as is sometimes suggested.

  3. Radioimmunological methods of determining hormones in the blood in physiological pregnancy and in abortions and premature delivery

    Significant changes are shown to occur in the level of sex hormones in blood at the risk of spontaneous abortion, missed abortion, or the mole. Determining the levels of estradiol, progesterone, chorial gonadotropin and testosterone in the blood serum using RIA yields immediate information on the hormonal function of the fetoplacental unit. This has diagnostic significance and can be used as a criterion for the application of complementary hormonal therapy when there is a risk of abortion or premature delivery. (author)

  5. Catholic attitudes toward abortion.

    1984-01-01

    In the US attitudes toward abortion in the 1980s seem to have reached a more liberal plateau, much more favored than in the 1960s or earlier, but not longer moving in a liberal direction. Catholic attitudes basically have followed the same trend. Traditionally Catholic support has been slightly lower than Protestant, and both are less inclined to support abortion than Jews or the nonreligious. During the 1970s support among non-black Catholics averaged about 10 percentage points below non-black Protestants. Blacks tend to be anti-abortion and thereby lower support among Protestants as a whole. A comparison of Protestants and Catholics of both races shows fewer religious differences -- about 7 percentage points. There are some indications that this gap may be closing. In 1982, for the 1st time, support for abortions for social reasons, such as poverty, not wanting to marry, or not wanting more children, was as high among Catholics as among Protestants. 1 of the factors contributing to this narrowing gap has been the higher level of support for abortion among younger Catholics. Protestants show little variation on abortion attitudes, with those over age 65 being slightly less supportive. Among Catholics, support drops rapidly with age. This moderate and possibly vanishing difference between Catholics and Protestants contrasts sharply with the official positions of their respective churches. The Catholic Church takes an absolute moral position against abortion, while most Protestant churches take no doctrinaire position on abortion. Several, such as the Unitarians and Episcopalians, lean toward a pro-choice position as a matter of social policy, though fundamentalist sects take strong anti-abortion stances. Few Catholics agree with their church's absolutist anti-abortion position. The big split on abortion comes between what are sometimes termed the "hard" abortion reasons -- mother's health endangered, serious defect in fetus, rape, or incest. Support among Catholics

  6. The Stratified Legitimacy of Abortions.

    2016-12-01

    Roe v. Wade was heralded as an end to unequal access to abortion care in the United States. However, today, despite being common and safe, abortion is performed only selectively in hospitals and private practices. Drawing on 61 interviews with obstetrician-gynecologists in these settings, we examine how they determine which abortions to perform. We find that they distinguish between more and less legitimate abortions, producing a narrative of stratified legitimacy that privileges abortions for intended pregnancies, when the fetus is unhealthy, and when women perform normative gendered sexuality, including distress about the abortion, guilt about failure to contracept, and desire for motherhood. This stratified legitimacy can perpetuate socially-inflected inequality of access and normative gendered sexuality. Additionally, we argue that the practice by physicians of distinguishing among abortions can legitimate legislative practices that regulate and restrict some kinds of abortion, further constraining abortion access. © American Sociological Association 2016.

  7. On the Wrongfulness of abortion

    Directory of Open Access Journals (Sweden)

    Gustavo Arosemena

    2017-07-01

    Full Text Available Abortion is seen as an immoral and unjust act by many. Nonetheless these views are under pressure to conform to the learned opinion on abortion. A variety of prestigious in the field of applied ethics support abortion in one way or another. And it is a dogma of modern liberalism that even if one is personally opposed to abortion, one must accept the neutral solution of its public permissibility. The present article defends the thesis that abortion is immoral and unjust against these contentions. With regards to the moral status of abortion, it argues that the prohibition of abortion is off a piece with the prohibition of killing generally, which is characterized by protecting all human beings equally. With regards to the compatibility of abortion permissibility with liberalism, the article argues that such a compromise is not neutral, but heavily rigged in favor of the interests and world-views of abortion proponents.

    Background In Papua New Guinea abortion is restricted under the Criminal Code Act. While safe abortions should available in certain situations, frequently they are not available to the majority of women. Sepsis from unsafe abortion is a leading cause of maternal mortality. Our findings form part of a wider, mixed methods study designed to identify complications requiring hospital treatment for post abortion care and to explore the circumstances surrounding unsafe abortion. Methods Through a six month prospective study we identified all women presenting to the Eastern Highlands Provincial Hospital following spontaneous and induced abortions. We undertook semi-structured interviews with women and reviewed individual case notes, extracting demographic and clinical information. Findings Case notes were reviewed for 56% (67/119) of women presenting for post abortion care. At least 24% (28/119) of these admissions were due to induced abortion. Women presenting following induced abortions were significantly more likely to be younger, single, in education at the time of the abortion and report that the baby was unplanned and unwanted, compared to those reporting spontaneous abortion. Obtained illegally, misoprostol was the method most frequently used to end the pregnancy. Physical and mechanical means and traditional herbs were also widely reported. Conclusion In a country with a low contraceptive prevalence rate and high unmet need for family planning, all reproductive age women need access to contraceptive information and services to avoid, postpone or space pregnancies. In the absence of this, women are resorting to unsafe means to end an unwanted pregnancy, putting their lives at risk and putting an increased strain on an already struggling health system. Women in this setting need access to safe, effective means of abortion. PMID:25329982

    2011-01-01

    Preterm birth is currently the most important problem in maternal-child health in the United States and possibly throughout the world. It complicates one in eight US deliveries, and accounts for over 85% of all perinatal morbidity and mortality. Although survival of preterm infants has increased steadily over the past four decades-due in large part to the use of antenatal corticosteroids, improvements in neonatal resuscitation, and the introduction of neonatal intensive care units-efforts to prevent preterm birth have been largely unsuccessful. On February 3, 2011, the US Food and Drug Administration (FDA) approved the use of progesterone supplementation (hydroxyprogesterone caproate) during pregnancy to reduce the risk of recurrent preterm birth in women with a history of at least one prior spontaneous preterm delivery. This is the first time that the FDA has approved a medication for the prevention of preterm birth, and represents the first approval of a drug specifically for use in pregnancy in almost 15 years. This article reviews the evidence behind the use of progesterone for the prevention of preterm birth, and provides guidelines for the use of progesterone supplementation in clinical practice. A number of areas of ongoing controversy are addressed, including the optimal formulation and route of administration, the safety of progesterone supplementation in pregnancy, and its proposed mode of action.

  12. RISK FACTORS FOR VERY PRETERM DELIVERY

    Full Text Available The aim of the research – assess risk factors for very preterm delivery in the Omsk region. Materials and methods. The main group comprised women with very preterm delivery (n = 64; сomparison group – pregnant women with a threat of interruption in terms of 22-27 weeks and successful preserving therapy (n = 63; control group – pregnant women in whom this pregnancy was taking place without the threat of interruption (n = 62. Results. Risk factors for very preterm delivery were bacterial vaginosis, specific vaginitis, kidney disease and the threat of interruption. There was a significant lead in streptococci (32.3 ± 5.8 %, especially group B (19.0 ± 4.9 % in the main group. The risk factor for very preterm delivery was infectious viral diseases transferred during pregnancy, observed in 12.7 ± 4.2 % of women in the main group, in 7.8 ± 3.3 % in the comparison group (p < 0.01 and in 4.8 ± 2,7 % – control (p < 0,001. In the main group, placental insufficiency was 2 times more common than in the comparison group and 13 times than in the control group. Every sixth pregnant of the main group had manifestations of gestosis. Such complications of gestation as the premature detachment of the normally inserted placenta (7.8 ± 3.3 % and inborn malformations of a fruit (1.6 ± 1.6 % were observed only in the main group. Conclusion. The results of the research and literature data showed that the significant influence on the level of very early premature births is due to: the age of the parents, the abuse of nicotine, alcohol, drugs, abortion, preterm birth, urinary tract and genital tract infections, severe somatic diseases, multiple pregnancies. In the structure of complications of gestation during miscarriages, placental insufficiency predominates, the threat of abortion, fetal growth retardation, and polyhydramnios.

    Folic acid supplementation has been suggested to reduce the risk of preterm birth. However, results from previous epidemiologic studies have been inconclusive. We investigated the hypothesis that folic acid supplementation and dietary folate intake during pre- and post-conception reduces the risk of preterm birth. We analyzed data from a birth cohort study conducted between 2010 and 2012 in Lanzhou, China, including 10,179 pregnant women with live singleton births. Compared to non-users, folic acid supplement users with >12-week duration had a reduced risk of preterm birth (OR 0.67, 95 % CI 0.55-0.83) with a significant dose-response relationship (P for trend = 0.01). A similar pattern was observed for spontaneous preterm birth. Stronger associations were seen for ever use of folic acid supplement and very preterm birth (OR 0.50, 95 % CI 0.36-0.69) and spontaneous very preterm birth (OR 0.42, 95 % CI 0.29-0.63). Dietary folate intake during preconception and pregnancy were also associated with reduced risk of preterm birth (OR 0.68, 95 % CI 0.56-0.83, OR 0.57, 95 % CI 0.47-0.70 for the highest quartiles, respectively), particularly for spontaneous very preterm (OR 0.41, 95 % CI 0.24-0.72, OR 0.26, 95 % CI 0.15-0.47 for the highest quartiles, respectively). There were also decreased risks of preterm birth observed per 10-µg increase in dietary folate intake, and similar associations were found after stratification by folic acid supplementation status. Our results suggest that folic acid supplementation and higher dietary folate intake during preconception and pregnancy reduces the risk of preterm birth, and the protective effect varies by preterm subtypes.

    Full Text Available Abstract Background Recently, attention has been focused on subsequent pregnancies among teenage mothers. Previous studies that compared the reproductive outcomes of teenage nulliparae and multiparae often did not consider the adolescents' reproductive histories. Thus, the authors compared the risks for adverse reproductive outcomes of adolescent nulliparae to teenagers who either have had an induced abortion or a previous birth. Methods In this retrospective cohort study we used perinatal data prospectively collected by obstetricians and midwives from 1990–1999 (participation rate 87–98% of all hospitals in Lower Saxony, Germany. From the 9742 eligible births among adolescents, women with multiple births, >1 previous pregnancies, or a previous spontaneous miscarriage were deleted and 8857 women Results In bivariate logistic regression analyses, compared to nulliparous teenagers, adolescents with a previous birth had higher risks for perinatal [OR = 2.08, CI = 1.11,3.89] and neonatal [OR = 4.31, CI = 1.77,10.52] mortality and adolescents with a previous abortion had higher risks for stillbirths [OR = 3.31, CI = 1.01,10.88] and preterm births [OR = 2.21, CI = 1.07,4.58]. After adjusting for maternal nationality, partner status, smoking, prenatal care and pre-pregnancy BMI, adolescents with a previous birth were at higher risk for perinatal [OR = 2.35, CI = 1.14,4.86] and neonatal mortality [OR = 4.70, CI = 1.60,13.81] and adolescents with a previous abortion had a higher risk for very low birthweight infants [OR = 2.74, CI = 1.06,7.09] than nulliparous teenagers. Conclusion The results suggest that teenagers who give birth twice as adolescents have worse outcomes in their second pregnancy compared to those teenagers who are giving birth for the first time. The prevention of the second pregnancy during adolescence is an important public health objective and should be addressed by health care providers who attend the first birth or the abortion

    To establish an effective and safe clinical fertility strategy by investigating the relationship between abortion history and pregnancy outcomes of in vitro fertilization (IVF) treatment. In the present retrospective cohort study, data from IVF treatment cycles performed at a reproductive center in China between October 1, 2014, and October 31, 2015, were assessed. Outcomes were compared between women with a history of induced abortion and those without. There were 1532 IVF treatment cycles included; 454 patients had a history of induced abortion and 1078 did not. The spontaneous abortion rate was significantly higher (30/170 [17.6%] vs 41/420 [9.8%]; P=0.002) and the endometrium was significantly thinner (8.8 ± 1.8 vs 9.7 ± 1.8 cm; P=0.001) among patients with a history of induced abortion compared with those without. In a subgroup analysis of patients with a history of induced abortion, women who had undergone surgical abortions had a lower live delivery rate compared with medical abortions (29/76 [38%] vs 101/378 [27%]; P=0.039).

    Abortion is illegal in Thailand unless the woman's health is at risk or pregnancy is due to rape. This study, carried out in 1999 in 787 government hospitals, examined the magnitude and profile of abortion in Thailand, using data collected prospectively through a review of 45,990 case records (of which 28.5% were classified as induced and 71.5% as spontaneous abortions) and face-to-face interviews with a sub-set of 1854 women patients. The estimated induced abortion ratio was 19.5 per 1000 live births. Almost half the induced abortions were in young women under 25 years of age, many of whom had little or no access to contraception. Socio-economic reasons accounted for 60.2% of abortions. Serious complications were observed in almost a third of cases, especially following abortions performed by non-health personnel. Government physicians' current provision of induced abortion went beyond the provisions of the law in almost half of cases, most commonly for intrauterine death and for congenital anomalies. The paper proposes a framework for policy discussions of the grey areas of maternal and fetal indications leading to legal reform, in order to facilitate safe abortion. A recommendation to amend the abortion law has been proposed to the Ministry of Public Health and the Thai Medical Council.

    In the UK in 1988, 13.3% of abortions were performed at 13 weeks' gestation or later. Reasons for this delay, in addition to the diagnosis through amniocentesis of a fetal abnormality, include late recognition of pregnancy, a change of mind about completing the pregnancy, a failure of primary care physicians to entertain the diagnosis of pregnancy, travel or financial problems, and referral difficulties and scheduling delays. Women with little education and very young women are most likely to present for late abortions. From 13-16 weeks, dilatation and evacuation is the safest method of pregnancy termination. The procedure can be made easier through preparation of the cervix with a prostaglandin pessary or Foley catheter. After 16 weeks, an instillation method is recommended; prostaglandin administration can be intro- or extra-amniotic. Complication rates at 13-19 weeks are 14.5/1000 for vaginal methods of abortion and 7.2/1000 for prostaglandin methods. The risk of complications is 3 times higher for women who have 2nd-trimester abortions through the National Health Service. Although it is not realistic to expect that late abortions ever can be eliminated, improved sex education and contraceptive reliability as well as reforms in the National Health Service could reduce the number substantially. To reduce delay, it is suggested that the National Health Service set up satellite day care units and 1-2 central units in each region to deal quickly with midtrimester abortions. Delays would be further reduced by legislation to allow abortion on request in at least the 1st trimester of pregnancy.

    Unsafe abortion is a significant but preventable cause of maternal mortality. Although induced abortion has been legal in Zambia since 1972, many women still face logistical, financial, social, and legal obstacles to access safe abortion services, and undergo unsafe abortion instead. This study provides the first estimates of costs of post abortion care (PAC) after an unsafe abortion and the cost of safe abortion in Zambia. In the absence of routinely collected data on abortions, we used multiple data sources: key informant interviews, medical records and hospital logbooks. We estimated the costs of providing safe abortion and PAC services at the University Teaching Hospital, Lusaka and then projected these costs to generate indicative cost estimates for Zambia. Due to unavailability of data on the actual number of safe abortions and PAC cases in Zambia, we used estimates from previous studies and from other similar countries, and checked the robustness of our estimates with sensitivity analyses. We found that PAC following an unsafe abortion can cost 2.5 times more than safe abortion care. The Zambian health system could save as much as US$0.4 million annually if those women currently treated for an unsafe abortion instead had a safe abortion.

    Full Text Available Objective: The aim of this study is to determine the frequency of unintended pregnancies, induced abortions and associated risk factors in women who have been admitted to hospitals in Hatay. Method: The subjects of this cross-sectional study were women who had been admitted to hospitals for the purposes of delivery or abortion, during a month-long period. A structured questionnaire was taken by 635 women. Unintended pregnancy was dependent variable. The independent variables were: age, husband’s age, civil status, total number of pregnancies, employment, use of family planning methods and family planning consultation services. Chi-square and Student's t-test were used to analyze of data. Results:21.4% of women reported using a family planning method when they got pregnant and 15.1% of the women said they did not want to be this pregnant. Ages of the women and their husbands, as well as the total number of pregnancies, were higher among unintended pregnancies (p<0.05. The frequency of unintended pregnancies increased where the husbands were unemployed, education levels of the couple were low, women were single or not officially married, disabled, or did not receive consultancy from their family physicians about family planning (p<0.05. 45.8% of all unintended pregnancies happened without the use of any family planning methods (p<0.01. 10.4% ended with spontaneous abortions and 4.25% were ended with induced abortions. The primary reason given for induced abortion was economic difficulties (44%. Conclusion: Unintended pregnancy rate is high in Hatay. It is estimated that almost half of all induced abortions are reported as spontaneous or therapeutic abortions.

    To determine the association between single previous abortion and pregnancy outcome in nulliparous women. A retrospective cohort study of all nulliparous women who delivered in a university-affiliated tertiary hospital (2009-2014). Pregnancy outcome of women with single previous first trimester abortion (study group) was compared to those of primigravida (control group). Of the 44 371 deliveries during the study period, 14 498 (32.6%) were of nulliparous women, of them 1501 (10.3%) had single previous abortion (abortion was independently associated with induction of labor (OR = 1.31, 95%C.I 1.04-1.63, p = 0.01), cesarean section (OR = 1.38, 95%C.I 1.18-1.60, p abortion no difference in pregnancy outcome was observed between those with previous induced termination of pregnancy and spontaneous abortion, except for increased risk for retained placenta in those with previous spontaneous abortion. Single early previous abortion in nulliparous women was associated with higher rate of induction of labor, cesarean section and retained placenta compared to primigravida women.

    In the long-term prospective controlled study reported here, 1509 general practitioners and 795 gynaecologists in England, Scotland and Wales are cooperating in providing information on the sequelae of abortion, especially on the problems of later pregnancies, subfertility and all reported morbidity, in particular psychiatric illness. Morbidity within 21 days after induced abortion, and considered to be related to induced abortion, was found in 10% of 6105 women who had an induced abortion in their index pregnancy, and there were major complications in 2.1%. The main factors affecting morbidity were the place of operation, gestation at termination, the method of termination, sterilization at the time of operation, and smoking habits. Several differences between National Health Service and private sector operations were found which could affect the morbidity rates. Possible means of reducing early morbidity are discussed. The outcome of the first post-index pregnancy in 745 women whose index pregnancy had ended in induced abortion and in 1339 controls was also compared. There was no statistically significant difference between cases and controls. Further analysis of a large number of pregnancies is required to permit confident interpretation of these observations.

    Sexual attitudes and behavior of adolescent females have been the topic of much interest over the past decade. Feelings about contraception, conception, and abortion have been described in relation to the adolescents' beliefs about the possibility of becoming pregnant, who will or will not "protect" them, and the influence of significant others on their decision making. This study explores differences in 35 women who had abortions during their teenage years with 36 women whose abortions occurred after the age of twenty. A demographic questionnaire, the Millon Clinical Multiaxial Inventory, and the Beck Depression Inventory were completed by women who were members of a patient-led support group. Premorbid psychiatric histories, the decision-making process itself, and distressing symptoms postabortion are reported. Specific differences in perceptions of coercion, preabortion suicidal ideation, and nightmares post-abortion were found in the adolescent group. Antisocial and paranoid personality disorders as well as drug abuse and psychotic delusions were found to be significantly higher in the group who aborted as teenagers. Hypotheses regarding the influences of adolescent development on mother/child relationships, power struggles, and the use of fantasy as a coping device are explored.

    1982-01-01

    This review of the longterm impact of induced abortion on reproductive function includes a comprehensive survey of the published and the preliminary literature. Over 200 anecdotal, descriptive, and observational epidemiologic reports were reviewed, and more than 150 studies in 11 languages from 21 countries that employed 1 of 4 standard research designs were identified. With these investigations as the foundation, the influence of induced abortion on secondary infertility, ectopic pregnancy, spontaneous abortion, shortened gestation, low birth weight, complications of pregnancy or delivery, and infant outcome were evaluated. The data from each of these investigations were systematically reexamined. In cases where the data were incomplete, additional information was requested from the authors. These studies were categorized by such factors as their research design, the type of abortion procedure used, and whether potential confounding variables were considered. To compare the relative power of studies, the 95% confidence interval around the point estimate of relative risk was calculated where possible. Studies that failed to consider the many confounding factors associated with both induced abortion and adverse pregnancy outcome were of limited value because women who obtain induced abortions differ substantially from those who do not. Results from these studies usually indicated a higher risk estimate than results from better designed, controlled investigations. Relying more heavily on the latter, the following were among the findings: 1) secondary infertility, which may be a rare late effect of a complicated abortion, occurs so infrequently that its risk is not significantly elevated, even in studies capable of detecting a 2-fold rise in relative risk; 2) ectopic pregnancy, which also may be a rare late effect of an abortion complicated by infection or trauma, occurs so infrequently that its risk is not significantly elevated in studies capable of detecting a 2

    The inflammatory response in preterm parturition is regulated by the innate immune system. Toll-like receptors (TLR)-2 and TLR-4 are innate immune receptors that recognize the microorganisms most frequently involved in amniotic cavity infections, which are associated with activating the inflammatory response at the maternal-fetal interface during preterm labor. This study aimed to evaluate the expression of TLR-2 and TLR-4 in maternal neutrophils in preterm labor. A cross-sectional study was conducted in the Obstetrics Care Unit of Botucatu Medical School, UNESP, Brazil. The preterm group was composed of 20 pregnant women who presented preterm labor and preterm delivery. The control group was composed of 20 nonlaboring pregnant women matched to the preterm group by gestational age. Neutrophils were isolated from peripheral blood and TLR expressions were performed by real-time polymerase chain reaction and flow cytometry. Gene expressions of TLR-2 and TLR-4 in neutrophils from the preterm group were statistically higher than expressions in neutrophils from the matched control group. The percentage of TLR-4+ neutrophils was higher in the preterm group than the matched control group, while the percentage of TLR-2+ neutrophils did not differ between groups. TLR-4 expression in maternal neutrophils is associated with spontaneous preterm labor. © 2017 S. Karger AG, Basel.

    Abortion has been a reality in women's lives since the beginning of recorded history, typically with a high risk of fatal consequences, until the last century when evolutions in the field of medicine, including techniques of safe abortion and effective methods of family planning, could have ended the need to seek unsafe abortion. The context of women's lives globally is an important but often ignored variable, increasingly recognised in evolving human rights especially related to gender and reproduction. International and regional human rights instruments are being invoked where national laws result in violations of human rights such as health and life. The individual right to conscientious objection must be respected and better understood, and is not absolute. Health professional organisations have a role to play in clarifying responsibilities consistent with national laws and respecting reproductive rights. Seeking common ground using evidence rather than polarised opinion can assist the future focus. Copyright 2010 Elsevier Ltd. All rights reserved.

    Quantitative fetal fibronectin testing has demonstrated accuracy for prediction of spontaneous preterm birth in asymptomatic women with a history of preterm birth. Predictive accuracy in women with previous cervical surgery (a potentially different risk mechanism) is not known. We sought to compare the predictive accuracy of cervicovaginal fluid quantitative fetal fibronectin and cervical length testing in asymptomatic women with previous cervical surgery to that in women with 1 previous preterm birth. We conducted a prospective blinded secondary analysis of a larger observational study of cervicovaginal fluid quantitative fetal fibronectin concentration in asymptomatic women measured with a Hologic 10Q system (Hologic, Marlborough, MA). Prediction of spontaneous preterm birth (<30, <34, and <37 weeks) with cervicovaginal fluid quantitative fetal fibronectin concentration in primiparous women who had undergone at least 1 invasive cervical procedure (n = 473) was compared with prediction in women who had previous spontaneous preterm birth, preterm prelabor rupture of membranes, or late miscarriage (n = 821). Relationship with cervical length was explored. The rate of spontaneous preterm birth <34 weeks in the cervical surgery group was 3% compared with 9% in previous spontaneous preterm birth group. Receiver operating characteristic curves comparing quantitative fetal fibronectin for prediction at all 3 gestational end points were comparable between the cervical surgery and previous spontaneous preterm birth groups (34 weeks: area under the curve, 0.78 [95% confidence interval 0.64-0.93] vs 0.71 [95% confidence interval 0.64-0.78]; P = .39). Prediction of spontaneous preterm birth using cervical length compared with quantitative fetal fibronectin for prediction of preterm birth <34 weeks of gestation offered similar prediction (area under the curve, 0.88 [95% confidence interval 0.79-0.96] vs 0.77 [95% confidence interval 0.62-0.92], P = .12 in the cervical

    Abortion is a sensitive issue; many cultures disapprove of it, which leads to under-reporting. This study sought to estimate the rate of abortion visibility in the city of Kerman, Iran-that is, the percentage of acquaintances who knew about a particular abortion. For estimating the visibility rate, it is crucial to use the network scale-up method, which is a new, indirect method of estimating sensitive behaviours more accurately. This cross-sectional study was conducted in Kerman, Iran using various methods to ensure the cooperation of clinicians and women. A total of 222 women who had had an abortion within the previous year (74 elective, 74 medical and 74 spontaneous abortions) were recruited. Participants were asked how many of their acquaintances were aware of their abortion. Abortion visibility was estimated by abortion type. 95% CIs were calculated by a bootstrap procedure. A zero-inflated negative binomial regression analysis was conducted to assess the variables related to visibility. The visibility (95% CI) of elective, medical and spontaneous abortion was 8% (6% to 10%), 60% (54% to 66%) and 50% (43% to 57%), respectively. Women and consanguineal family were more likely to be aware of the abortion than men and affinal family. Non-family members had a low probability of knowing about the abortion, except in elective cases. Abortion type, marital status, sex of the acquaintance and closeness of the relationship were the most important determinants of abortion visibility in the final multifactorial model. This study shows the visibility rate to be low, but it does differ among social network members and by the type of abortion in question. This difference might be explained through social and cultural norms as well as stigma surrounding abortion. The low visibility rate might explain the low estimates of abortion rates found in other studies. Published by the BMJ Publishing Group Limited.

    In induced abortion, the method, the risk of complications and the economic cost of the abortion are determined by gestational age. The aim of this study was to describe the determinants of induced abortion delay until the second trimester of pregnancy in Barcelona. We performed a cross-sectional study of induced abortions due to the physical or mental health of the woman (Barcelona, 2004-2005; N=9,175). The city's induced abortion register provided data on gestational age at abortion (dependent variable), educational level, age, cohabitation with the partner, number of children previous abortions, and type of center. Adjusted prevalence ratios (aPR) were calculated with log-binomial regression models. A total of 7.7% of induced abortions were second-trimester abortions and 99.3% were performed in private centers. Compared with women with a university education, those with primary education or less had an aPR of 1.8 (95% confidence interval [95%CI]: 1.4-2.2) of delaying the abortion until the second trimester. A higher proportion of second-trimester abortions were also recorded in women aged less than 18 years old (aPR=2.6; 95%CI: 2.0-3.4), women not cohabiting with their partners (aRP=1.4; 95% CI: 1.2-1.6) and in public centers (aPR=2.8; 95% CI: 2.2-3.7). No differences were found in induced abortion delay among women with previous abortions and those without. Induced abortion delay until the second trimester of pregnancy was associated with low educational level, young ages, not cohabiting with a partner, and public centers. This study demonstrates the existence of socioeconomic inequalities in access conditions to abortion services.

    In France, induced abortion was legalized under certain conditions since the January 1975 and December 1979 laws suspended the effects of Article 317 of the French Penal Code that forbade induced abortion. For more than 15 years, induced abortion has been part of current gynecological practice. Adverse effects of abortions have been reduced. In the upcoming years, the interest in drug-induced abortion and abortion under local anesthesia will increase due to a concern for reducing risks that deteriorate physical integrity and women's gynecological/obstetrical future. Induced abortion still remains a very important act, if not serious, in a woman's life. Prevention of induced abortion remains the absolute medical objective and is necessary for information campaigns on contraceptives, especially among youth. If accessible and equal access to induced abortion is becoming a reality in France, abortion will always remain a failure and proof for women that they have recourse to abortion. Induced abortions have remained relatively stable in France (170,000 in 1980; 181,154 in 1991). The abortion rate ranges from 20 to 25 per 100 live births. 50% of women of reproductive age will have an induced abortion in their life. The fertility rate in France has been 1.8 since 1976. First trimester abortion-related mortality is less than 1/100,000. Abortion-related mortality increases with gestational age (0.5/100,000 at 8 weeks vs. 1.1/100,000 at 12 weeks). It is also associated with the anesthesia used (0.15 for local anesthesia vs. 0.58 for general anesthesia). The leading causes of abortion-related mortality are infection, pulmonary embolism, and anesthetic accidents. Immediate complications of induced abortion are anesthetic accidents, hemorrhage, uterine perforations, accumulation of blood in the uterus, cervical tears, and vagal discomfort. In France, the induced abortion related-perforation rate is between 0.2% and 1.2%. Perforation is more likely after 10 weeks and under

    To compare and analyze socioeconomic aspects and the emotional experience of women with spontaneous or induced abortion and in women living in the outskirts of São Paulo. A prospective case-control study carried out from July 2008 to March 2010, involving semi-structured interviews with women who presented a previous diagnosis of abortion and who had been admitted to two public hospitals in the outskirts of São Paulo. The study included 100 women with diagnosis of abortion and were hospitalized for curettage. Eleven women who reported induced abortion (11%) represented the case group. The control group (n=22) was selected at a 2:1 ratio according to the following procedure: for every case of induced abortion, the next two cases of spontaneous abortion at the same hospital. A semistructured interview was conducted with questions regarding emotional aspects and family, social and economic context. The women with induced abortion compared to the group with spontaneous abortion had lower educational level, with more frequent elementary level (82 versus 36%, p=0.04), lower income (median, R$ 1,000.00 versus R$ 1,400.00, p=0.04), lower personal income (median, R$ 200.00 versus R$ 333.00, p=0.04), higher frequency of negative feelings upon suspicion (82 versus 22%, p=0.004) and confirmation (72 versus 22%, p=0.03) of pregnancy. Among women looking for health care in hospitals in the outskirts of São Paulo, induced abortion is related to unfavorable socioeconomic conditions, which affects the emotional experiences of suspicion and confirmation of pregnancy.

    Full Text Available Objetivos:avaliar, no primeiro e segundo trimestres da gravidez, a correlação entre o comprimento do colo uterino e a ocorrência de parto prematuro espontâneo. Métodos:em 641 grávidas do pré-natal geral, a medida do comprimento do colo uterino foi realizada em dois momentos: entre a 11ª e a 16ª e entre a 23ª e a 24ª semana da gravidez. A avaliação do colo uterino foi feita pela ultra-sonografia transvaginal, com a grávida em posição ginecológica e tendo realizado previamente esvaziamento da bexiga. O comprimento do colo uterino foi medido linearmente do seu orifício interno ao externo. A medida do comprimento do colo uterino foi correlacionada com a idade gestacional no momento do parto. Para comparação das médias do grupo de grávidas que tiveram parto prematuro e a termo utilizamos o teste t de Student. A sensibilidade, especificidade, taxa de falso-positivos, falso-negativos e acurácia para o parto prematuro foram calculadas para os comprimentos de colo menores ou iguais a 30 mm, 25 mm e 20 mm. Resultados:a medida do comprimento do colo uterino entre a 11ª e a 16ª semana de gestação não apresentou diferença significativa entre o grupo de parto prematuro e o grupo a termo (40,6 mm e 42,7 mm, respectivamente, p=0,2459. A diferença entre os grupos, no entanto, foi significativa quando o colo foi medido entre a 23ª e a 24ª semana de gravidez (37,3 mm para o grupo que evoluiu com parto prematuro e 26,7 mm para o grupo a termo, p=0,0001, teste t de Student. Conclusões:o comprimento do colo uterino entre a 11ª e a 16ª semana de gravidez não foi significativamente diferente entre as gestantes com parto prematuro ou a termo. No entanto, na 23ª e 24ª semana esta diferença foi significativa, podendo ser um método de predição da prematuridade.Purpose: to evaluate, in the first and second trimesters of pregnancy, the correlation between cervical length and spontaneous preterm delivery.

    Preterm birth (delivery before 37 completed weeks of gestation) is common and rates are increasing. In the past, medical efforts focused on ameliorating the consequences of prematurity rather than preventing its occurrence. This approach resulted in improved neonatal outcomes, but it remains costly in terms of both the suffering of infants and their families and the economic burden on society. Increased understanding of the pathophysiology of preterm labor has altered the approach to this problem, with increased focus on preventive strategies. Primary prevention is a limited strategy which involves public education, smoking cessation, improved nutritional status and avoidance of late preterm births. Secondary prevention focuses on recurrent preterm birth which is the most recognisable risk factor. Widely accepted strategies include cervical cerclage, progesterone and dedicated clinics. However, more research is needed to explore the role of antibiotics and anti-inflammatory treatments in the prevention of this complex problem.

    to analyze women's perception in relation to their partner's reaction and behavior during the abortion process in two Brazilian capitals, associating the variables from women who suffered a spontaneous abortion with those from women who induced it. semi-structured, questionnaire-based interviews were conducted with 285 women who underwent spontaneous abortion and 31 who reported having induced it. The data were analyzed using the thematic analysis technique, and, subsequently, by the IBM SPSS Statistics Standard Edition software program. The significance level was set at p abortion referred to the partner as the person who could not find out about the abortion (pabortion was associated with the partner's absence at the time pregnancy was confirmed (p = 0.02) and, in Sao Paulo-SP, with their negative reaction to news of the pregnancy (p = 0.04) and lack of participation in the abortion process (p abortion process as an important factor. The specifics of each capital denote the influence of the geographic and cultural dimension, indicating the need to take into account the particulars of each region in Brazil while considering a holistic approach to women's health.

    Complications due to unsafe abortion cause high maternal morbidity and mortality, especially in developing countries. This study describes post-abortion complication severity and associated factors in Kenya. A nationally representative sample of 326 health facilities was included in the survey. All regional and national referral hospitals and a random sample of lower level facilities were selected. Data were collected from 2,625 women presenting with abortion complications. A complication severity indicator was developed as the main outcome variable for this paper and described by women's socio-demographic characteristics and other variables. Ordered logistic regression models were used for multivariable analyses. Over three quarters of abortions clients presented with moderate or severe complications. About 65% of abortion complications were managed by manual or electronic vacuum aspiration, 8% by dilation and curettage, 8% misoprostol and 19% by forceps and fingers. The odds of having moderate or severe complications for mistimed pregnancies were 43% higher than for wanted pregnancies (OR, 1.43; CI 1.01-2.03). For those who never wanted any more children the odds for having a severe complication was 2 times (CI 1.36-3.01) higher compared to those who wanted the pregnancy then. Women who reported inducing the abortion had 2.4 times higher odds of having a severe complication compared to those who reported that it was spontaneous (OR, 2.39; CI 1.72-3.34). Women who had a delay of more than 6 hours to get to a health facility had at least 2 times higher odds of having a moderate/severe complication compared to those who sought care within 6 hours from onset of complications. A delay of 7-48 hours was associated with OR, 2.12 (CI 1.42-3.17); a delay of 3-7 days OR, 2.01 (CI 1.34-2.99) and a delay of more than 7 days, OR 2.35 (CI 1.45-3.79). Moderate and severe post-abortion complications are common in Kenya and a sizeable proportion of these are not properly managed

  13. Article Commentary: Activity in Pregnancy for Patients with a History of Preterm Birth

    Full Text Available Preterm birth remains a leading cause of neonatal morbidity and mortality throughout the world. Numerous risk factors for preterm birth have been identified, including non-Hispanic black race, a variety of social and behavioral factors, infections, and history of a prior preterm delivery. Of these, a history of prior spontaneous preterm birth is one of the strongest risk factors. Traditionally, women with a history of preterm birth or those deemed at high risk for preterm delivery have been placed on bed rest or a reduced activity regimen during their pregnancy. However, there is little evidence to support this recommendation. Recent research has suggested that regular physical activity and exercise during pregnancy is safe and does not increase the risk of preterm delivery. Therefore, physicians should encourage women with a history of preterm birth to exercise throughout pregnancy according to guidelines published by the American College of Obstetricians and Gynecologists as long as they are receiving regular prenatal care and their current health status permits exercise. However, there are no randomized controlled trials evaluating exercise prescription in women with a history of preterm birth, hence additional research is needed in this area.

    Anti-secretory factor is a protein that regulates secretory and inflammatory processes and preterm birth is associated with inflammation. Therefore, our hypothesis was that anti-secretory factor might play a role in immune reactivity and homeostasis during pregnancy. Following spontaneous onset of labor and preterm or term delivery, placenta biopsies were collected. The levels of anti-secretory factor and markers of inflammation (CD68, CD163) and vascularization (CD34, smooth muscle actin) were analyzed by immunohistochemistry. The 61 placental biopsies included 31 preterm (preterm placentas exhibited lower levels of anti-secretory factor (p = 0.008) and larger numbers of CD68-positive cells (p Preterm placentas had blood vessel of smaller diameter (p = 0.036) indicative of immaturity. The level of interleukin-6 in cord blood was higher after very preterm than term birth, suggesting a fetal inflammatory response. The placenta level of anti-secretory factor was positively correlated to the length of gestation (p = 0.025) and negatively correlated to the levels of the inflammatory markers CD68 (p = 0.015) and CD163 (p = 0.028). Preterm delivery is associated with low levels of anti-secretory factor in placenta. Inflammation, a potential trigger of preterm birth, is more pronounced in the preterm placenta and inversely related to the placental level of anti-secretory factor, suggesting both a link and a potential target for intervention. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    To test the hypothesis that sleep disorder diagnosis would be associated with increased risk of preterm birth and to examine risk by gestational age, preterm birth type, and specific sleep disorder (insomnia, sleep apnea, movement disorder, and other). In this observational study, participants were from a cohort of nearly 3 million women in California between 2007 and 2012. Inclusion criteria were women with singleton neonates liveborn between 20 and 44 weeks of gestation without chromosomal abnormalities or major structural birth defects linked to a hospital discharge database maintained by the California Office of Statewide Health Planning and Development and without mental illness during pregnancy. Sleep disorder was defined based on International Classification of Diseases, 9th Revision, Clinical Modification diagnostic code (n=2,265). Propensity score matching was used to select a referent population at a one-to-one ratio. Odds of preterm birth were examined by gestational age (less than 34 weeks, 34-36 weeks, and less than 37 weeks of gestation) and type (spontaneous, indicated). Prevalence of preterm birth (before 37 weeks of gestation) was 10.9% in the referent group compared with 14.6% among women with a recorded sleep disorder diagnosis. Compared with the referent group, odds (95% CI, P value, percentage) of preterm birth were 1.3 (1.0-1.7, P=.023, 14.1%) for insomnia and 1.5 (1.2-1.8, P<.001, 15.5%) for sleep apnea. Risk varied by gestational age and preterm birth type. Odds of preterm birth were not significantly increased for sleep-related movement disorders or other sleep disorders. Insomnia and sleep apnea were associated with significantly increased risk of preterm birth. Considering the high prevalence of sleep disorders during pregnancy and availability of evidence-based nonpharmacologic interventions, current findings suggest that screening for severe presentations would be prudent.

  16. Abortion: taking the debate seriously.

    Voluntarily induced abortion has been under permanent dispute and legal regulations, because societies invariably condemn extramarital pregnancies. In recent decades, a measure of societal tolerance has led to decriminalize and legalize abortion in accordance with one of two models: a more restricted and conservative model known as therapeutic abortion, and the model that accepts voluntary abortion within the first trimester of pregnancy. Liberalization of abortion aims at ending clandestine abortions and decriminalizes the practice in order to increase reproductive education and accessibility of contraceptive methods, dissuade women from interrupting their pregnancy and, ultimately, make abortion a medically safe procedure within the boundaries of the law, inspired by efforts to reduce the incidence of this practice. The current legal initiative to decriminalize abortion in Chile proposes a notably rigid set of indications which would not resolve the three main objectives that need to be considered: 1) Establish the legal framework of abortion; 2) Contribute to reduce social unrest; 3) Solve the public health issue of clandestine, illegal abortions. Debate must urgently be opened to include alternatives in line with the general tendency to respect women's decision within the first trimester of pregnancy.

    This study examines the association between religion and attitudes toward the practice of abortion and abortion policy in Brazil. Drawing upon data from the 2002 Brazilian Social Research Survey (BSRS), we test a number of hypotheses with regard to the role of religion on opposition to the practice of abortion and its legalization. Findings indicate that frequently attending Pentecostals demonstrate the strongest opposition to the practice of abortion and both frequently attending Pentecostals and Catholics demonstrate the strongest opposition to its legalization. Additional religious factors, such as a commitment to biblical literalism, were also found to be significantly associated with opposition to both abortion issues. Ultimately, the findings have implications for the future of public policy on abortion and other contentious social issues in Brazil.

  18. Late abortion meeting, Paris / France.

    On January 27 and 28, 1989 a workshop and a meeting were organized in Paris by Mouvement Francais pour le Planning Familial (MFPF/France) and the IPPF Europe Region. The workshop was held on the first day. 24 staff and volunteers from Planned Parenthood Associations of 15 countries attended, reviewing abortion laws, the definition of therapeutic abortion, and the incidence and problems of second trimester abortion. Second trimester abortion is available in only a few European countries. Second trimester abortions are rare in France (about 2000 per annum), and in 1986 1717 French women travelled to England in order to seek an abortion. All late abortions are performed for serious reasons. Older women may mistake signs of pregnancy for the onset of the menopause; and women fearful of social or familial punishment, especially teenagers, may be reluctant to consult a doctor. The experiences of Denmark and Sweden, where the problem is partially solved, suggest some strategies: optimize accessibility of contraceptive services, particularly for women at higher risk of late abortion; diminish the taboo surrounding abortion, so that women are less frightened to seek help at an early stage of pregnancy; make abortion services available in all regions of the country; avert time-consuming enforced waiting periods or consent for minors; and stimulate public information campaigns on the importance of seeking help early. On January 28 a meeting involving about 200 participants took place at the Universite Paris Dauphine, Salle Raymond Aron. Speakers at the meeting discussed the issue of late abortion in Europe, the difficulties of obtaining late abortions, counseling, medical problems, the woman's point of view, and possible solutions. At the close of the meeting, the MFPF called on the French government to modify some of the articles in the Penal Code that restrict women's access to safe and legal abortion.

  1. Public funding of abortions and abortion counseling for poor women.

    1997-01-01

    This essay seeks to reveal the weakness in arguments against public funding of abortions and abortion counseling in the US based on economic, ethico-religious, anti-racist, and logical-consistency objections and to show that public funding of abortion is strongly supported by appeals to basic human rights, to freedom of speech, to informed consent, to protection from great harm, to justice, and to equal protection under the law. The first part of the article presents the case against public funding with detailed considerations of the economic argument, the ethico/religious argument, the argument that such funding supports racist genocide or eugenic quality control, and arguments that a logical inconsistency exists between the principles used to justify the legalization of abortions and arguments for public funding. The second part of the article presents the case
