Racial/ethnic disparities among women receiving intrauterine transfusions for alloimmunization at a single fetal treatment center.

Disparities are prevalent in numerous areas of healthcare. We sought to investigate whether there were racial/ethnic disparities among pregnant women with the most severe form of alloimmunization who require intrauterine transfusions (IUT). We reviewed patients who underwent IUT for alloimmunization at a single fetal treatment center between 2015 and 2020. This "IUT cohort" was compared to an "Alloimmunization cohort": patients seen at our institution with a diagnosis of alloimmunization during pregnancy, who did not receive IUT. We collected maternal demographics including self-identified race/ethnicity and primary language, transfusion, and antibody characteristics. The cohorts were compared using unpaired t-tests, Mann-Whitney tests, and Fischer's exact tests, as appropriate. The IUT cohort included 43 patients and the alloimmunization cohort included 1049 patients. Compared to the alloimmunization cohort, there were significantly more patients of Latina descent in the IUT cohort (23.3% vs. 3.4%, p < .0001), and more non-English speakers (18.6% vs. 4.6%, p = .001). Twenty-one percent (9/43) of patients had immigrated to the United States, all of whom had pregnancies or miscarriages in their country of origin. A third of patients had new antibodies identified on serial screens during the current pregnancy. Significantly more women of Latina ethnicity and non-English speakers required IUTs compared to the cohort of women with alloimmunization. Insufficient access to care prior to arriving in the United States and among racial and ethnic minorities in the United States may contribute to these findings. Providers should be cognizant of potential, racial, and ethnic inequalities among women receiving intrauterine transfusions.

Beyond counting induced abortions, miscarriages and stillbirths to understanding their risk factors: analysis of the 2017 Ghana maternal health survey.

BACKGROUND: Inasmuch as induced abortions, miscarriages and stillbirths constitute common adverse pregnancy outcomes contributing to poor maternal health, there is paucity of literature about these in Ghana. We investigated the factors associated with induced abortions, miscarriages and stillbirths in Ghana. METHODS: Data derived from the 2017 Ghana Maternal Health Survey was used in this study. Women aged 15-49 constituted the target for the study. This study examined the relationship between socio-demographic characteristics and induced abortions, stillbirths and miscarriages. Subsequently, multivariable binary logistic regression models were fitted to investigate the factors associated with induced abortions, stillbirths and miscarriages at 95 % confidence interval (CI). RESULTS: The prevalence of miscarriages, induced abortions and stillbirths in Ghana in 2017 were 10.8 %, 10.4 % and 2 % respectively. Induced abortions (12.9 %) and miscarriages (11.1 %) were found to be higher among urban residents whiles rural residents had more of stillbirths (2.1 %). Compared to women aged 15-24, those in all age categories had lower odds of experiencing induced abortions, with the lowest odds occurring among women aged 35-49 (AOR = 0.26, 95 % CI = 0.21-32). Conversely, women of all age categories had higher odds of experiencing miscarriages compared to those aged 15-24 with the highest odds among those aged 25-34 (AOR = 1.62, 95 % CI = 1.39-1.89). Women with at least primary education were more likely to experience miscarriages than those with no formal education, with those with higher level of education having the highest odds (AOR = 1.42, 95 % CI = 1.13-1.78). While the likelihood of induced abortions was lower among Muslims, compared to Christians (AOR = 0.65, 95 % CI = 0.52-0.82), the odds of miscarriages were higher among Muslims, compared to Christians (AOR = 1.31, 95 % CI = 1.13-1.52). Women with parity 1 or more were less likely to experience induced abortions, miscarriages and stillbirths compared to those with parity 0. CONCLUSIONS: Our study indicates that efforts to limit induced abortions, miscarriages and stillbirths in Ghana need to focus on the disparities in socio-demographic characteristics of women. Synergy between government health institutions and the private sector cannot be left out if much success can be achieved in efforts to subside the current prevalence of induced abortions, stillbirths and miscarriages confronting the country.

Racial Disparities in Mental Health Outcomes Among Women With Early Pregnancy Loss.

OBJECTIVE: To explore the relationship between race and depression symptoms among participants in an early pregnancy loss clinical trial. METHODS: We performed a planned secondary analysis of a randomized trial by comparing treatments for medical management of early pregnancy loss. We hypothesized that Black participants would have higher odds of risk for major depression (measured with the CES-D [Center for Epidemiological Studies-Depression] scale) 30 days after early pregnancy loss treatment when compared with non-Black participants. We analyzed the data as a cohort, with the primary exposure being race and secondary exposure being high adverse childhood experience scores (measured with the Adverse Childhood Experience scale). Our primary outcome was risk for major depression (score of 21 or higher on the CES-D scale) 30 days after early pregnancy loss treatment. RESULTS: Three hundred participants diagnosed with a nonviable intrauterine pregnancy from 5 to 12 weeks of gestation were randomized as part of the original trial from May 2014 to April 2017. Of 275 respondents included in this analysis, 120 [44%] self-identified as Black and 155 [56%] self-identified as non-Black. After early pregnancy loss treatment, 65 [24%] participants were at risk for major depression. Black participants had an increased risk for major depression (57%) after early pregnancy loss treatment compared with non-Black participants (43%; odds ratio [OR] 2.02; 95% CI 1.15-3.55). After adjustment for risk for baseline depression, adverse childhood experience score, and parity, the odds of risk for major depression 30 days after pregnancy loss treatment remained higher for Black participants when compared with non-Black participants (OR 2.02; 95% CI 1.15-3.55; adjusted OR 2.48; 95% CI 1.28-4.81). CONCLUSION: Overall, approximately one quarter of women who experience an early pregnancy loss are at an increased risk for major depression 30 days after treatment. This risk is about twice as high for Black women compared with non-Black women. There is a need for appropriate mental health resources for women undergoing early pregnancy loss care.

Reproductive health of Roma women in Slovakia.

OBJECTIVE: In most indicators of the way of life, the Roma community is generally different from the majority population and dominant culture. The objective of the study was to describe factors affecting the health of the Roma living in Slovakia, with an emphasis on the sexual and reproductive health of Roma women, and report on the results of analysis of high-risk pregnancies of Roma women in the district of Rimavská Sobota, Slovakia. METHODS: A retrospective study of medical documentation was used. The results were analyzed using the absolute and relative frequencies. Statistical methods were used. RESULTS: A total of 1,256 high-risk pregnancies were analyzed, of which 622 (49.52%) were in Roma women. The average age of Roma respondents was lower by 5 years compared to non-Roma. The age of Roma women at the first pregnancy was statistically significantly lower compared to non-Roma (p < 0.001). The Roma respondents achieved statistically significantly lower levels of education than non-Roma. There was a demonstrably higher number of pregnancies as well as a higher number of artificial and spontaneous abortions per Roma woman. These results were statistically significant. For Roma women, pregnancy began to be risky demonstrably earlier than for non-Roma (p < 0.001). There was a statistically significant difference in attending prenatal counselling. Roma women attended prenatal counselling statistically significantly less frequently than non-Roma (p < 0.001). A significant statistical dependence was found between attending prenatal counselling and the onset of pregnancy problems in Roma women. There was no significant difference in the incidence of other diseases associated with high-risk pregnancy among Roma and non-Roma respondents. CONCLUSION: The findings indicate that Roma women are exposed to health problems in the area of sexual and reproductive health in Slovakia. In the approach to the Roma, it is essential to focus on improving accessibility to health care, prevention, knowledgeableness and effectively preventing, eradicating and strongly penalizing all forms of discrimination in access to health care, especially for Roma women, who are more likely to receive health care.

Abortion in rural Ghana: Cultural norms, knowledge and attitudes.

Using qualitative methodology, semi-structured questionnaires were administered to participants in the Barakese subdistrict of Ghana in order to understand the extent to which men and women have knowledge of family planning services and in what ways cultural norms, practices, and attitudes toward abortion affect the decision to abort. Women in the community pursue abortion using unsafe methods, despite fear of shame, bleeding, infection, or death, as the perceived cost of maintaining the pregnancy is greater. Protective factors that were reported to dissuade women from pursuing unsafe abortion include fear of social disgrace, divine retribution, and death. Women reported the inability to control the timing of their pregnancies, despite harboring knowledge of family planning. Concerned about perceived side effects of modern family planning methods, respondents chose to use fertility awareness methods or to use no contraception. There remains a gap between knowledge of the benefits of and the actual use of family planning methods, leading to unwanted pregnancy and seeking unsafe abortion. Intensified health promotion and education regarding side effects to combat misconceptions related to contraception, as well as expanding alternative contraceptive options to all regions of Ghana, are critical to improve uptake.

Culpability, blame, and stigma after pregnancy loss in Qatar.

BACKGROUND: Following a miscarriage many women report feeling guilty and culpable for what has happened particularly when aspects of societal blame and stigma are involved. This research investigated the impact of cultural context on the experience of miscarriage. In particular, it focused on how elements of stigma and blame are linked to notions of miscarriage etiology and risk among Qatari women. METHODS: The research used an ethnographic approach. The data was collected over 18 months of fieldwork in Qatar, using semi-structured face to face interviews, and participant observation. A purposive sample of 40 women (primary participants) who had recently miscarried, participated in the study. Potential subjects were initially identified in the Women's Hospital and were consented, and then interviewed in Arabic either in the hospital or at their preferred location. The interviews were audio recorded, transcribed and translated into English. Additional key interviews were performed with 20 secondary participants related to the miscarriage cohort including family members and husbands. Inductive thematic analysis of content was performed manually to extract themes. RESULTS: Two main themes emerged from the material looking specifically at miscarriage aftermaths: rhetorics of blame, self-blame and feelings of guilt; and miscarriage attitudes. Overall society is sympathetic and miscarriage is seen as normal and not particularly worrying, but understood to be upsetting to women. However, findings suggest there is some ambivalence around blame, culpability and stigma applied to miscarriage; some participants perceived miscarriage as a relatively normal and common event, whereas, others felt that miscarriage is resounding stigma and shame. CONCLUSION: Miscarriage aftermaths are embedded in social, cultural and religious frameworks in relation to notions of risk and causation. Attention should be paid to ensure women and those around them are given appropriate and robust information about miscarriage causation to deflect discourses of blame that may be employed and reduce harm to women who suffer miscarriage.

Procedure-related risk of miscarriage following chorionic villus sampling and amniocentesis.

OBJECTIVES: To estimate the procedure-related risks of miscarriage following chorionic villus sampling (CVS) and amniocentesis in a large unselected screened population, and to determine whether these risks are consistent with those reported in systematic reviews and meta-analyses. METHODS: This was a retrospective cohort study carried out on data obtained from a large fetal medicine unit in the UK between January 2009 and May 2018. We included all women with singleton pregnancy who booked for pregnancy care at our unit before 20 weeks' gestation, after excluding those with multiple pregnancy, major fetal defect, pregnancy termination and loss to follow-up. We estimated the risk of miscarriage in women who underwent a CVS or amniocentesis as well as in those who did not have an invasive procedure. The procedure-related risk of miscarriage was estimated as risk difference (95% CI) between the two groups. Univariate and multivariate regression analyses were used to derive odds ratios (95% CI) and determine which maternal and pregnancy characteristics provided a significant contribution in the prediction of miscarriage and whether CVS or amniocentesis provided a significant independent contribution. RESULTS: During the study period, 45 120 singleton pregnancies were booked for pregnancy care at our hospital, of which 1546 had an invasive procedure. We excluded 1429 (3.2%) pregnancies due to fetal defects, termination of pregnancy or missing outcomes. Of the 43 691 pregnancies included in the study population, 861 underwent CVS and 375 amniocentesis. In pregnancies that underwent CVS, the risk of miscarriage was 1.5% (13/861), compared with 1.2% (476/39 152) in pregnancies that had first-trimester combined screening and did not have an invasive procedure (P = 0.437). In pregnancies that underwent an amniocentesis, the risk of miscarriage was 0.8% (3/375), compared with 1.2% (491/42 463) in those that did not undergo an invasive procedure (P = 0.520). Univariate and multivariate regression analysis demonstrated that there was no significant contribution in the prediction of the risk of miscarriage from CVS (P = 0.399 and P = 0.592, respectively) or amniocentesis (P = 0.543 and P = 0.550, respectively). The risk of procedure-related loss attributed to CVS was 0.29% (95% CI, -0.53 to 1.12%) and that following amniocentesis was -0.36% (95% CI, -1.26 to 0.55%), which was not significantly different from the risk in women who did not have any procedure. CONCLUSIONS: The procedure-related risks of miscarriage following CVS and amniocentesis in our study are considerably lower than those currently quoted and are consistent with the estimates of such risks reported by systematic reviews and meta-analyses.

Customary practices, domestic violence, and psychosomatic pain among adolescent mothers in Turkey.

BACKGROUND: Adolescent motherhood is present in many societies worldwide, including Turkey. AIMS: We aimed to determine the demographical and cultural characteristics of adolescent mothers, lifetime domestic violence and history of miscarriage, and whether they suffer from any kind of medically unexplained (psychosomatic) pain in a study in south-eastern Turkey. METHODS: We included 501 mothers in this case-control study. The study group comprised 228 mothers who gave their first deliveries at or before 19 years of age, and the control group consisted of 273 mothers who first delivered after 19 years of age. The case-control study was conducted between February and April 2013 in Diyarbakir, Turkey. RESULTS: Adolescent mothers marry more frequently with their relatives. They have a higher prevalence of culture-bound customary applications such as bride price. They are less likely to be asked for their consent to marry and tend to have more children. They are more frequently victims of domestic violence and more often report medically unexplained psychosomatic pain. CONCLUSIONS: Adolescent motherhood is still a public health problem that seems to be related to certain culture-bound customary practices, continuing domestic violence across generations, increased number of children, and more prevalent psychosomatic pain.

Maternal and fetal prognosis of subsequent pregnancy in black African women with peripartum cardiomyopathy.

BACKGROUND: The aim of this study was to describe maternal and fetal outcomes after pregnancy complicated by peripartum cardiomyopathy (PPCM). METHODS: We included women that had subsequent pregnancy (SSP) after PPCM and assessed maternal prognosis and pregnancy outcomes, in-hospital up to one week after discharge. Clinical and echocardiographic data were collected comparing alive and deceased women. Factors associated with pregnancy outcomes were assessed. RESULTS: Twenty-nine patients were included, with a mean age of 26.7 ± 4.6 years and a mean gravidity number of 2.3 ± 0.5 of. At the last medical control before subsequent pregnancy, there was no congestive heart failure, the mean left ventricular diastolic diameter (LVDD) was 53 ± 4 mm and the left ventricular ejection fraction (LVEF) was ≥50% in 13 cases (44.8%). Maternal outcomes were marked by 14 deaths (48.3%). Among the factors tested in univariate analysis, LVEF at admission had an excellent receiver-operating characteristic (ROC) curve to predict maternal mortality (AUC = 0.95; 95% CI 0.87-1, p < 0.001), with a cut off value of < 40% (sensitivity = 93% and specificity = 87%). Concerning fetal outcomes, baseline LVEF had the best area under the curve (AUC) to predict abortion or prematurity among all variables (AUC = 0.75; 95% CI 0.58-092, p = 0.003), with a cut-off value of < 50% (sensitivity = 79%, specificity = 67%). CONCLUSIONS: SSP outcomes are still severe in our practice. Maternal mortality remains high and is linked to ventricular systolic function at admission (due to pregnancy), while fetal outcomes are linked to baseline LVEF before pregnancy.

The effect of CAG repeats length on differences in hirsutism among healthy Israeli women of different ethnicities.

PURPOSE: Variations in the degree of hirsutism among women of different ethnic backgrounds may stem from multiple etiologies. Shorter length of the polymorphic CAG repeats of the androgen receptor (AR) gene may be associated with increased activity of the receptor leading to hirsutism. We hypothesized that there are ethnic differences in the degree of hirsutism that is unrelated to androgen levels among Israeli women, and that the CAG repeats length may contribute to these differences. Anti-androgenic therapies, such as spironolactone, could be suggested if a shorter CAG repeats length is found to affect the difference in the degree of hirsutism between the ethnic groups. METHODS: Healthy Israeli Jewish women aged 18-45 years of Ashkenazi and non-Ashkenazi origin were invited to participate. Hirsutism was assessed using the simplified Ferriman-Gallwey (sFG) score, and serum total testosterone levels were measured as well. The CAG repeats length was determined by PCR. Methylation-sensitive methods were used to detect the fractional activity of each allele, and the weighted mean was calculated for the CAG repeats length. RESULTS: One-hundred and eight women were recruited (49 Ashkenazi and 59 non-Ashkenazi). The Ashkenazi women had a significantly lower degree of hirsutism (P<0.01), lower mean BMI (P = 0.003), total testosterone levels (P = 0.017), and longer weighted bi-allelic CAG repeats mean (P = 0.015) compared to non-Ashkenazi women. For the group as a whole, there was a significant negative correlation between the number of CAG repeats in the AR gene and the sFG score, while the number of repeats was not related to testosterone levels. Stepwise logistic regression revealed that ethnic origin and the CAG repeats length were the strongest factors affecting hirsutism (P<0.001, P = 0.03, respectively). CONCLUSIONS: There is a significant difference in the degree of hirsutism between Ashkenazi and non-Ashkenazi women in Israel that is partially explained by CAG repeats length.

The Pain and Pride of 'Angel Mothers': Disappointments and Desires Around Reproductive Loss in Romania.

In this article, I highlight how Romanian women make sense of the losses of pregnancies and babies. Based on 15 months of fieldwork in a Transylvanian town, and on interviews with and observations among 'angel mothers' (women who have lost unborn or live-born children) in the Romanian capital Bucharest, I discuss the disappointments and desires that surface when reproduction goes awry. The criticisms of these 'angel mothers' throw into sharp relief wider disappointments with biomedical, political, and religious establishments, and continuing social struggles in postcommunist Romania. Although women's personal predicaments are thus deeply connected to broader structural shortcomings, their coping strategies are highly intimate and nonpolitical. Women focus on creating a spiritual bond between themselves and their lost babies-one that transcends the hardships of earthly life and makes women proud to be the mothers of little angels.

Effect of ethnicity on clinical presentation and risk of antiphospholipid syndrome in Roma and Caucasian patients with systemic lupus erythematosus: a multicenter cross-sectional study.

AIM: To determine if there are ethnic differences in the prevalence of antiphospholipid syndrome (APS), clinical presentation and autoantibody profile between Roma and Caucasian patients with systemic lupus erythematosus (SLE). METHOD: A cross-sectional study was conducted including data from Roma and Caucasian SLE patients consecutively attending six hospitals in Spain. Socio-demographic characteristics, prevalence of APS, clinical and analytical features of SLE and APS were compared between ethnic groups. RESULTS: Data from 52 Roma and 98 Caucasian SLE patients were included. Roma SLE patients had a higher risk (odds ratio 2.56, 95% CI 1.02-6.39) and prevalence of APS (28.8% vs. 13.3%, P = 0.027). Furthermore, Roma SLE patients had a statistically significant higher prevalence of abortions (23.5% vs. 10.2%, P = 0.049). In relation to other APS diagnostic criteria, Roma SLE patients had a non-statistically significant higher prevalence of fetal deaths (14.3% vs. 5.1%, P = 0.106) and thrombotic events (21.1% vs. 12.2%, P = 0.160). In relation to SLE clinical features, Roma patients had a significantly higher prevalence of arthritis (75% vs. 57.1%, P = 0.034) and non-significant higher prevalence of serositis (44.2% vs. 29.6%, P = 0.104), discoid lesions (11.5% vs. 5.1%, P = 0.191), oral ulcers (46.1% vs. 34.7%, P = 0.218) and livedo reticularis (21.1% vs. 15.3%, P = 0.374). No statistically significant differences were found in the Systemic Lupus International Collaborating Clinics Damage Index or the autoimmune serological profile. CONCLUSION: Prevalence and risk of APS were significantly higher in Roma SLE patients. Furthermore, Roma patients had a significantly higher prevalence of abortions and a non-significant higher prevalence of fetal deaths and thrombotic events.

Birds, meat, and babies: the multiple realities of fetuses in Qatar.

This paper explores miscarriage in a variety of Qatari contexts to reveal the multiple realities of the unborn. During 18 months of ethnographic research, a range of settings in which fetuses emerged were explored. The unborn are represented and imagined differently, particularly in relation to the ways they are located, with multiple beings emerging according to the context and position of the stakeholder. This paper considers fetuses produced within these contexts and considers how they can be different beings simultaneously. The paper reveals how categories meant to define these beings are in flux and are constantly negotiated; it reflects moments of ambiguity. The paper serves as an illustration of the way in which value-afforded pregnancy materials affects the contexts in which they emerge; this then loops back as context dictates the significance of the material, hence multiple realities of these beings.

Association of uterine fibroids and pregnancy outcomes after ovarian stimulation-intrauterine insemination for unexplained infertility.

OBJECTIVE: To investigate the association of non-cavity-distorting uterine fibroids and pregnancy outcomes after ovarian stimulation-intrauterine insemination (OS-IUI) in couples with unexplained infertility. DESIGN: Secondary analysis from a prospective, randomized, multicenter clinical trial investigating fertility outcomes after OS-IUI. SETTING: Reproductive Medicine Network clinical sites. PATIENT(S): Nine hundred couples with unexplained infertility who participated in the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS) clinical trial. INTERVENTION(S): Participants were randomized to one of three arms (clomiphene citrate, letrozole, or gonadotropins), and treatment was continued for up to four cycles or until pregnancy was achieved. MAIN OUTCOMES MEASURE(S): Conception (serum hCG increase), clinical pregnancy (fetal cardiac activity), and live birth rates. RESULT(S): A total of 102/900 participants (11.3%) had at least one documented fibroid and a normal uterine cavity. Women with fibroids were older, more likely to be African American, had a greater uterine volume, lower serum antimüllerian hormone levels, and fewer antral follicles than women without fibroids. In conception cycles, clinical pregnancy rates were significantly lower in participants with fibroids than in those without uterine fibroids. Pregnancy loss before 12 weeks was more likely in African American women with fibroids compared with non-African American women with fibroids. There was no difference in conception and live birth rates in subjects with and without fibroids. CONCLUSION(S): No differences were observed in conception and live birth rates in women with non-cavity-distorting fibroids and those without fibroids. These findings provide reassurance that pregnancy success is not impacted in couples with non-cavity-distorting fibroids undergoing OS-IUI for unexplained infertility. CLINICAL TRIAL REGISTRATION NUMBER: NCT01044862.

Racial Disparities in Fertility Care: an Analysis of 4537 Intrauterine Insemination Cycles.

BACKGROUND: Studies suggest that race may affect access to fertility treatments and their outcomes. We examined whether race affects the following: duration of infertility prior to seeking evaluation, diagnosis, treatment cycle characteristics, and outcomes. MATERIALS AND METHODS: Design: Retrospective cohort. SETTINGS: Academic fertility center. PATIENTS: 4537 intrauterine insemination ± ovulation induction (IUI ± OI) cycles/1495 patients. INTERVENTIONS: IUI following: (i) OI with either clomiphene citrate or gonadotropins and (ii) ultrasound-monitored natural cycles. OUTCOME MEASURES: Duration of infertility prior to seeking treatment, SART diagnosis, treatment cycle characteristics and outcomes (spontaneous abortion (SABR), clinical (CPR) and multiple pregnancy rates (MPR)). RESULTS: Asians and Hispanics compared to Caucasians waited significantly longer prior to seeking fertility evaluation (p < 0.01). The mean age of patients seeking infertility evaluation did not differ between groups nor did the type of treatment initially chosen by the patients. Idiopathic infertility was more common among Caucasians (p < 0.05, compared to all others) while PCOS and tubal factor infertility were more frequent among Hispanics (p < 0.05, compared to Caucasian, Asian, and mixed ancestry women) and decreased ovarian reserve was more common among African-Americans (p < 0.01, compared to Caucasians, Asians, and Hispanics). Gonadotropin cycle characteristics including dosing and duration of treatment, follicular recruitment, peak estradiol levels, and endometrial lining thickness differed between certain groups. However, no difference was found in CPR, MPR, and SABR between groups. CONCLUSION: Race affects timely access to infertility care, diagnosis, and treatment cycle characteristics but not outcomes. Considering the nation's growing multiracial population, understanding the effect of race on fertility care becomes increasingly important.

[Association between the C46T polymorphism of coagulation factor â « gene and the involvement of factor â « activity in patients with unexplained recurrent spontaneous abortion].

OBJECTIVE: To explore the association between the C46T polymorphism of coagulation factor Ⅻ (FⅫ) gene and the involvement of FⅫ activity (FⅫ:C) in patients with unexplained recurrent spontaneous abortion (URSA), and to elucidate its role in the pathogenesis of URSA. METHODS: This study included 203 patients with URSA (URSA group) and 171 healthy women with at least one child and no history of infertility or miscarriage (control group) in the southern area of Zhejiang Province. The C46T polymorphism of the FⅫ gene was analyzed with matrix-assisted laser desorption/ionization time of flight-mass spectrometry (MALDI-TOF-MS) in all subjects. The values of prothrombin time, activated partial thromboplastin time (APTT), fibrinogen, FⅫ:C and other coagulant parameters were determined. The frequency distribution of the wild-type (CC), heterozygote (CT), homozygote (TT) genotypes and C and T alleles were compared between the patients and controls. A comprehensive analysis of association was conducted between C46T genotypes and the FⅫ:C levels in URSA patients. RESULTS: The CC, CT, TT genotypes of the FⅫ gene were observed in 7 (3.4%, 7/203), 83 (40.9%, 83/203) and 113 (55.7%, 113/203) patients with URSA versus 7 (4.1%, 7/171), 46 (26.9%, 46/171) and 118 (69.0%, 118/171) controls. The frequency of CT in the patients with URSA was significantly higher than that in controls, but the frequency of TT in the patients was lower than that in controls (χ(2)=7.939, OR=1.884, 95%CI: 1.210-2.935, P<0.05). The frequencies of allele C and allele T were observed in 97 (23.9%, 97/406) and 309 (76.1%, 309/406) patients with URSA versus 60 (17.5%, 60/342) and 282 (82.5%, 282/342) controls. The distribution frequency of allele T in URSA group was lower than that in control group (χ(2)=4.510, OR=1.475, 95%CI: 1.029-2.115, P<0.05). The FⅫ: C levels in the patients were (102±13)% in CC genotype, (78±11)% in CT genotype and (59±9)% in TT genotype, respectively. The differences of the FⅫ: C levels between the CC and CT, CT and TT, CC and TT genotypes in the patients were significant (all P<0.05). CONCLUSIONS: The low level of FⅫ:C maybe result from the T allele of the FⅫ gene in URSA patients. The CT genotype might be relative to the pathogenesis of URSA in a Chinese Han female population from the southern area of Zhejiang province.

Association between p53 polymorphism at codon 72 and recurrent spontaneous abortion.

p53 gene plays an important role in apoptosis, which is necessary for successful invasion of trophoblast cells. The change from an arginine (Arg) to a proline (Pro) at codon 72 can influence the biological activity of p53, which predisposes to an increased risk of recurrent spontaneous abortion (RSA). In order to investigate the association between p53 polymorphism at codon 72 and RSA, we conducted this meta-analysis. Pubmed, Embase and Web of science were used to identify the eligible studies. Odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the strength of the association. Six studies containing 937 cases of RSA and 830 controls were included, and there was one study deviated from Hardy-Weinberg equilibrium (HWE). There was a significant association between p53 polymorphism at codon 72 and RSA in recessive model (Pro/Pro vs. Pro/Arg+Arg/Arg; OR=1.60, 95% CI: 1.14-2.24) and co-dominant model (Pro/Pro vs. Arg/Arg; OR=1.47, 95% CI: 1.02-2.12) whether the study that was deviated from HWE was eliminated or not. A significant association was observed in allelic model (Pro vs. Arg; OR=1.28, 95% CI: 1.04-1.57) after exclusion of the study that was deviated from HWE. No association was noted in recessive model (Pro/Pro+Pro/Arg vs. Arg/Arg; OR=1.05, 95% CI: 0.86-1.30) and co-dominant model (Pro/Arg vs. Arg/Arg; OR=0.96, 95% CI: 0.77-1.19). Subgroup analysis by ethnicity also indicated a significant association between p53 polymorphism at codon 72 and RSA in Caucasian group. No heterogeneity and publication bias were found. Our meta-analysis implied that p53 polymorphism at codon 72 carries high maternal risk of RSA.

[Analysis of the association of human leukocyte antigen DQ gene polymorphisms with unexplained recurrent spontaneous abortion among ethnic Han Chinese from Wenzhou region].

OBJECTIVE: To assess the association of human leukocyte antigen DQ gene polymorphisms with unexplained recurrent spontaneous abortion (URSA) among ethnic Han Chinese from Wenzhou region. METHODS: 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. RESULTS: 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, P<0.05). The HLA-DQB1*05:03 allele was present among the healthy females with a frequency of 3.03%, and was not detected among females with URSA. For both males and females, the HLA-DQB1*05:02 allele were only typed in control group with frequencies of 6.06% and 5.30%, respectively. The sharing of HLA-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, P<0.05). CONCLUSION: The increased sharing of HLA-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.

Influence of race and ethnicity on in vitro fertilization outcomes: systematic review.

OBJECTIVE: We conducted a systematic review to evaluate the influence of race and ethnicity on clinical pregnancy and live birth outcomes after in vitro fertilization (IVF). STUDY: We searched PubMed, EMBASE, Web of Science, CINAHL, POPLINE, and Cochrane Central, and hand-searched relevant articles published through July 22, 2015. STUDY APPRAISAL AND SYNTHESIS METHODS: Two reviewers independently evaluated abstracts to identify studies that compared clinical pregnancy rates and live birth rates for ≥2 racial and/or ethnic groups after nondonor IVF cycles. RESULTS: Twenty-four studies were included. All 5 US registry-based studies showed that black, Hispanic, and Asian women had lower clinical pregnancy rates and/or live birth rates after IVF, compared with white women. Similarly, most clinic-specific studies reported significant disparities in these primary outcomes, potentially attributable to differences in infertility diagnosis, spontaneous abortion, and obesity. Studies varied with respect to definitions of race/ethnicity, inclusion of first cycles vs multiple cycles for individual women, and collected covariates. Most studies were limited by sample size, inadequate adjustment for confounding, selection bias, and extensive missing data. CONCLUSIONS: Although current evidence points to race and ethnicity, especially black race, as strong predictors of poorer outcomes after IVF, the utility of results is constrained by the limitations described.

Racial variation in the number of spontaneous abortions before a first successful pregnancy, and effects on subsequent pregnancies.

OBJECTIVE: To assess the relationship between race and spontaneous abortion, whether the relationship varies by risk factors, and the effect of spontaneous abortions on subsequent pregnancies. METHODS: A retrospective study was undertaken using data collected in London, UK, between 1988 and 2000. Logistic regression evaluated histories of spontaneous abortion and associations with small-for-gestational-age and preterm births in black African, black Caribbean, and South Asian women relative to white European women. Interactions with risk factors were assessed. RESULTS: Overall, 196 040 women were included. Compared with white Europeans, the odds of a previous spontaneous abortion were increased in black African (adjusted odds ratio [aOR] 1.20; 95% confidence interval [CI] 1.12-1.29) and black Caribbean women (aOR 1.31; 95% CI 1.21-1.41). The strength of the association with black African race increased with age (P=0.002), and the association with South Asian race increased with age and body mass index (P<0.001 for both). Spontaneous abortion was associated with preterm birth in all races, but was strongest in black African women (aOR 1.47; 95% CI 1.29-1.67). CONCLUSION: The greater incidence of spontaneous abortion in black African and black Caribbean women should prompt further study of risk factors in relation to race. The interaction with age in black African and South Asian women could be important for counseling in relation to timing of pregnancy.
