RESUMO

OBJECTIVES: Violence against women is a widespread public health concern with severe effects to women's sexual and reproductive health, including higher risks for miscarriage or stillbirth, unintended pregnancy and induced abortion. This study examined the association between women exposure to physical violence, psychological violence and sexual and reproductive health outcomes (contraceptive use, miscarriage or stillbirth and abortion) in Germany. METHODS: This study used a cross-sectional research design to analyze data on violence against women and sexual and reproductive health (SRH) outcomes collected through the German Health Interview and Examination Survey for Adults, Wave 1, between 2008 and 2011 (n = 3149 women, aged 18-64 years). Multivariable logistic regression models were used to assess the association between experiences of violence among women and the presence of sexual and reproductive health outcomes, considering the influence of socio-demographic and health-related factors (age, marital status, socioeconomic status, social support, number of children, alcohol consumption, health status, chronic conditions). RESULTS: Three associations remained significant (p<0.05) in fully-adjusted models: (i) exposure to physical violence by a parent or caregiver and birth control pill utilization (aOR, adjusted Odds Ratio, 95% CI: 1.36, 1.02-1.81) (ii) exposure to physical violence since the age of 16 and miscarriage or stillbirth (aOR, 95%CI: 1.89, 1.17-3.04); and (iii) exposure to psychological violence by a parent or caregiver and abortion (aOR, 95%CI: 1.87, 1.30-2.70). CONCLUSIONS: The results suggest that adult German women who experienced physical or psychological violence since the age of 16, including violence perpetrated by a parent or caregiver, were more likely to report miscarriage or stillbirth and abortion. Direct assessment of violence experiences against women should be conducted by healthcare professionals in clinical encounters, particularly by obstetrics and gynaecological specialists, for the prevention of women´s adverse sexual and reproductive health outcomes. Furthermore, violence should be treated as a major public health concern and addressed through a multisectoral approach, involving the healthcare and educational sectors, researchers and relevant policymakers.

RESUMO

A disturbance in the metabolism of homocysteine in both the mother and the fetus has been implicated in several placental vasculopathy-related disorders, including pregnancy loss. This study aimed to provide insights into the potential role of homocysteine, Vitamin B12, and folic acid in early pregnancy losses, with a specific focus on the Turkish population. The results of 93 pregnant women who experienced miscarriage between 5 and 14 gestational weeks and 93 healthy pregnant women at the same gestational weeks were compared. The demographic and pregnancy characteristics of all pregnant women were recorded. Vitamin B12, folic acid, and homocysteine levels were measured in serum samples obtained from the groups at similar gestational weeks. In addition, any associations between these biomarkers and different types of pregnancy loss, such as spontaneous abortion and missed abortion, were evaluated. Vitamin B12 and folic acid serum levels were significantly lower in women with miscarriages (P = .019, P < .001, respectively). Homocysteine levels were higher in the patient group (P < .001). Logistic regression analysis showed that a higher homocysteine level was the only predictive factor of miscarriage (P = .001, odds ratio = 0.596); however, folic acid and Vitamin B12 were not predictive factors. There was no significant difference in homocysteine and micronutrient levels between women with missed abortions and women with spontaneous abortions (P > .05). Our results support the continuing evidence of a link between maternal homocysteine levels and fetal loss. However, in exploring the shared pathways in the underlying mechanisms causing the 2 forms of pregnancy loss, maternal blood analysis showed no relationship.

RESUMO

Background: The novel coronavirus disease 2019 (COVID-19) was more devastating in people with comorbidities such as advanced age and immunodeficiency. Another group affected by COVID-19 was pregnant women. Immunological changes during pregnancy and conditions such as gestational diabetes and pre-eclampsia that occur during pregnancy also have effects on the fetus. The aim of this study was to analyze the effects of PCR-proven COVID-19 infection during pregnancy on fetus and newborn. Methods: Between December 2019 and October 2021, data from pregnant women with COVID-19 symptoms or a history of contact with people with COVID-19, infected with PCR-proven COVID-19 virus, were analyzed retrospectively. Clinical and laboratory data of pregnant women were analyzed. Death data associated with COVID-19 were evaluated. Clinical and laboratory findings of newborns related to COVID-19 and mortality data related to COVID-19 were recorded. The study received approval from the Gazi Yasargil Training and Research Hospital ethics committee (09.07.2021/853). Results: We evaluated 327 pregnant women who were followed up in our hospital and whose deliveries ended in live birth, stillbirth, miscarriage, or curettage. One hundred eighty-five (56.6%) of the pregnant women had at least one COVID-19-related symptom. We evaluated the data of 306 live births, 21 intrauterine fetal deaths, and 13 postnatal deaths. Among the postnatal deaths, five infants succumbed directly due to COVID-19 infection. A total of 23 live-born babies (7.5%) were classified as small for gestational age (SGA), while 80 babies (26.1%) were born before 37 weeks of gestation, and 32 babies (10.4%) were born before 32 weeks. Cord blood gas analysis revealed that 19 infants (6.3%) had pH < 7 and base excess (BE) < -12. The rate of perinatal asphyxia was significantly higher in babies born to mothers who did not survive (p = 0.027). A considerable number of infants, 119 (40.3%), were admitted to the neonatal intensive care unit (NICU). Among the seven infants with positive PCR results admitted to the NICU, five (4.2%) did not survive. Conclusion: While COVID-19 infection in pregnancy seriously affects mortality and morbidity in pregnant women, it also causes mortality and morbidity on the fetus.

RESUMO

PURPOSE: To determine the factors influencing the likelihood of biochemical pregnancy loss (BPL) after transfer of a euploid embryo from preimplantation genetic testing for aneuploidy (PGT-A) cycles. METHODS: The study employed an observational, retrospective cohort design, encompassing 6020 embryos from 2879 PGT-A cycles conducted between February 2013 and September 2021. Trophectoderm biopsies in day 5 (D5) or day 6 (D6) blastocysts were analyzed by next generation sequencing (NGS). Only single embryo transfers (SET) were considered, totaling 1161 transfers. Of these, 49.9% resulted in positive pregnancy tests, with 18.3% experiencing BPL. To establish a predictive model for BPL, both classical statistical methods and five different supervised classification machine learning algorithms were used. A total of forty-seven factors were incorporated as predictor variables in the machine learning models. RESULTS: Throughout the optimization process for each model, various performance metrics were computed. Random Forest model emerged as the best model, boasting the highest area under the ROC curve (AUC) value of 0.913, alongside an accuracy of 0.830, positive predictive value of 0.857, and negative predictive value of 0.807. For the selected model, SHAP (SHapley Additive exPlanations) values were determined for each of the variables to establish which had the best predictive ability. Notably, variables pertaining to embryo biopsy demonstrated the greatest predictive capacity, followed by factors associated with ovarian stimulation (COS), maternal age, and paternal age. CONCLUSIONS: The Random Forest model had a higher predictive power for identifying BPL occurrences in PGT-A cycles. Specifically, variables associated with the embryo biopsy procedure (biopsy day, number of biopsied embryos, and number of biopsied cells) and ovarian stimulation (number of oocytes retrieved and duration of stimulation), exhibited the strongest predictive power.

RESUMO

BACKGROUND: Women who suffer an early pregnancy loss require specific clinical care, aftercare, and ongoing support. In the UK, the clinical management of early pregnancy complications, including loss is provided mainly through specialist Early Pregnancy Assessment Units. The COVID-19 pandemic fundamentally changed the way in which maternity and gynaecological care was delivered, as health systems moved to rapidly reconfigure and re-organise services, aiming to reduce the risk and spread of SARS-CoV-2 infection. PUDDLES is an international collaboration investigating the pandemic's impact on care for people who suffered a perinatal bereavement. Presented here are initial qualitative findings undertaken with UK-based women who suffered early pregnancy losses during the pandemic, about how they navigated the healthcare system and its restrictions, and how they were supported. METHODS: In-keeping with a qualitative research design, in-depth semi-structured interviews were undertaken with an opportunity sample of women (N = 32) who suffered any early pregnancy loss during the COVID-19 pandemic. Data were analysed using a template analysis to understand women's access to services, care, and networks of support, during the pandemic following their pregnancy loss. The thematic template was based on findings from parents who had suffered a late-miscarriage, stillbirth, or neonatal death in the UK, during the pandemic. RESULTS: All women had experienced reconfigured maternity and early pregnancy services. Data supported themes of: 1) COVID-19 Restrictions as Impractical & Impersonal; 2) Alone, with Only Staff to Support Them; 3) Reduction in Service Provision Leading to Perceived Devaluation in Care; and 4) Seeking Their Own Support. Results suggest access to early pregnancy loss services was reduced and pandemic-related restrictions were often impractical (i.e., restrictions added to burden of accessing or receiving care). Women often reported being isolated and, concerningly, aspects of early pregnancy loss services were reported as sub-optimal. CONCLUSIONS: These findings provide important insight for the recovery and rebuilding of health services in the post-pandemic period and help us prepare for providing a higher standard of care in the future and through any other health system shocks. Conclusions made can inform future policy and planning to ensure best possible support for women who experience early pregnancy loss.

RESUMO

Objective: To study and compare the clinical effects of cervical pessary and progesterone for preventing preterm birth in singleton pregnant women with a short cervical length (CL). Methods: This study was a prospective cohort study. A total of 148 pregnant women with CL≤25 mm, as determined by ultrasound examination performed before 28 weeks of pregnancy, were included in the study. All subjects were admitted to West China Second Hospital, Sichuan University between August 2020 and December 2022. According to their treatment plans, the pregnant women were divided into a cervical pessary group (n=55) and a progesterone group (n=93). Spontaneous preterm birth before 37 weeks of pregnancy was defined as the main outcome index. Preterm birth (abortion) or spontaneous preterm birth (abortion) before 37, 34, 32, 30, and 28 weeks of pregnancy, mean extended gestational age, neonatal morbidity, and neonatal mortality were the secondary outcome indicators. The pregnancy outcomes and the neonatal outcomes of the two groups were compared and statistically analyzed. Results: There was no statistically significant difference in the incidence of preterm birth (including iatrogenic preterm birth, spontaneous preterm birth, and abortion) before 37, 34, 32, 30, and 28 weeks between the cervical pessary group and the progesterone group. When iatrogenic preterm birth was excluded, the incidence of spontaneous preterm birth before 37 weeks was lower in the cervical pessary group (23.6%) than that in the progesterone group (41.9%), with the difference between the two groups being statistically significant (P=0.024). There was no statistically significant difference in the incidence of spontaneous preterm birth (including miscarriage) before 34, 32, 30, and 28 weeks. There was no statistically significant difference in the incidence of neonatal morbidity, the rate of transfer to the neonatal care unit after birth, and the neonatal mortality rate between the two groups. Multivariate logistic analysis showed that treatment with cervical pessary was a protective factor for spontaneous preterm birth before 37 weeks compared to progesterone therapy. Conclusion: Using cervical pessary to prevent spontaneous preterm birth in singleton pregnant women with a short cervical length in the second trimester can significantly reduce the incidence of spontaneous preterm birth before 37 weeks.

RESUMO

BACKGROUND: Spontaneous abortion is a common complication of pregnancy that can lead to adverse physical and psychological outcomes for women. Vitamin D is reported to be associated with reproductive functions, whereas its casual effects on abortion remains unclear. MATERIALS AND METHODS: In this study, a two-sample Mendelian randomization (MR) analysis was performed to systematically assess the causal relationships between serum 25 hydroxyvitamin D [25(OH)D] concentration and the risk of spontaneous abortion. GWAS summary data of 25(OH)D were used as exposure, and data of spontaneous abortion was considered as outcome. A retrospective study was additionally conducted to verify the MR results. RESULTS: MR estimates showed that a higher 25(OH)D level was potentially associated with decreased risk of spontaneous abortion (IVW, OR = 0.98, 95%CI = 0.90-1.06; MR Egger, OR = 0.94, 95%CI = 0.84-1.05; Weighted median, OR = 0.93, 95%CI = 0.82-1.06; Weighted mode, OR = 0.93, 95%CI = 0.84-1.03), though the P-value was not statistically significant. The retrospective study also produced consistent result of Vitamin D's protective role to spontaneous abortion. The P-value was very close to statistical significance (P = 0.053). CONCLUSIONS: This study reports the potential protective role of serum 25(OH)D concentration to spontaneous abortion, suggesting that increased vitamin D levels may decrease the risk of abortion. Further larger prospective studies and/or even randomized controlled trials are needed to confirm causal relationship between vitamin D and abortion.

RESUMO

BACKGROUND: Early pregnancy loss is a traumatic event following which clients may experience psychological morbidities. Mental illness is associated with multiple obstetric and social factors surrounding the period of pregnancy loss. The aim of this study was to find the prevalence of depression and anxiety before and after undergoing spontaneous or induced first trimester abortion and to analyze demographic and obstetric factors associated with it. METHODS: This is an observational study conducted as Kathmandu Medical College (KMC) for a duration of one year from September 2022 to August 2023. All clients with abortion were screened for psychiatric morbidity using the The Hospital Anxiety and Depression Scale (HADS). Each client was assessed at first hospital visit and then at two weeks and two months following abortion. Level of anxiety and depression was analyzed in relation to socio-demographic factors and the type of abortion. RESULTS: 171 clients with pregnancy loss were enrolled. Pre-abortion, severe anxiety was present in 6(13%) clients with spontaneous abortion. Pre-abortion, mild to severe anxiety was present in 31 (67.3%) clients and at two weeks and two months in 11 (23.9%) and 11 (23.9%) clients respectively. In clients undergoing induced abortion, varying levels of anxiety was present in 54(43.2%) pre-abortion, and 48(38.4%) and 54(43.2%) clients at two weeks and two months. Mild to moderate depression was seen in 21 (45.6%) among spontaneous abortion and 51 (40.8%) clients among induced abortion. Mean score on HADS decreased with time. CONCLUSIONS: Anxiety and depression were common following early pregnancy loss. Rate of anxiety seems to decrease with time in spontaneous abortion but in induced abortion it remains persistent. Rate of depression tends to decrease with time for both types of abortion.

RESUMO

BACKGROUND: Depression is a common mental disorder with a much higher prevalence in women than in men. Although there has been a gradual increase in research on the association between reproductive health and depression, there is still some inconsistency in the evidence of the relationship between pregnancy loss and depression. This study aimed to investigate the relationship between pregnancy loss and depressive symptoms. METHODS: We analyzed data from the 2007-2020 National Health and Nutrition Examination Survey (NHANES), which included female participants aged 20 to 80 years. Pregnancy loss was determined based on participants' self-reported number of pregnancies and pregnancy outcomes. Depressive symptoms were measured using the Patient Health Questionnaire (PHQ-9, score ≥ 10). Multivariate logistic regression, smoothed curve fitting, and generalized additive modeling were used to examine the association between pregnancy loss and depression. We also performed sensitivity analyses and subgroup analyses to verify the robustness and specificity of the findings. RESULTS: A total of 12,873 female participants were included in our study, of which 1,595 (12.39%) were categorized as depressed. Multivariate logistic regression results indicated that experiencing a pregnancy loss increased the risk of prevalence of depression in women (for 1 loss: OR = 1.31, 95% CI 1.15,1.50; for 2 or more losses: OR = 1.58, 95% CI 1.38, 1.81). When sensitivity analyses were performed, an association between pregnancy loss and depression was found in both multivariate linear regressions with PHQ-9 scores as a continuous variable and multivariate logistic regressions with a threshold of 5 PHQ-9 scores. The association between pregnancy loss and depression remained stable across subgroups. CONCLUSION: Pregnancy loss correlated with elevated PHQ-9 scores and a heightened risk of depression in adult women across the United States. Focusing on the incidence of adverse pregnancy events in the female population may help prevent or early recognize the onset of depression.

RESUMO

Mpox (monkeypox) is a neglected tropical disease that has received increased attention since the multi-nation outbreak that began in 2022. The virus is endemic in West and Central Africa, where the Democratic Republic of the Congo (DRC) is the most affected country. Clade I monkeypox virus (MPXV) infection is endemic in the DRC and has an overall case fatality rate of 10.6% among children and adults. A study conducted in Sankuru Province, DRC, from 2007 to 2011 demonstrated that 75% of pregnant women with mpox had miscarriages or stillbirth. Further analysis of a stillborn fetus showed that MPXV could infect both the placenta and fetus, causing congenital infection. No additional cases of Clade I MPXV in pregnant women were reported until a new outbreak occurred in South Kivu Province during 2023 and 2024. Eight pregnant women having Clade I MPXV infection were identified, of whom four had either miscarriages or stillbirth, representing a 50% fetal mortality rate. These reports confirm previous data from the DRC that indicate the capability of Clade I MPXV to affect the fetus, causing congenital infection and fetal loss in a high percentage of cases. In this article, we review both past and new data from the DRC on the effects of Clade I MPXV during pregnancy and discuss the association of mpox with fetal loss.

RESUMO

BACKGROUND: We sought to improve the current understanding of how climate change impacts women's reproductive health in sub-Saharan Africa. OBJECTIVES: We investigated the relationship between maternal heat exposure and miscarriage (pregnancy ending before 20 weeks gestation) in a South African setting. DESIGN: Population-based cohort study. METHODS: Our study involved data for pregnancies collected via a health and demographic surveillance system in rural KwaZulu-Natal, South Africa between 2012 and 2016. Data from the South African Weather Service were used to compute maternal exposure to heat during the following time windows for each pregnancy: during the month preceding conception (T1) and during the week preceding the study outcome (either a miscarriage or no miscarriage, T2). Heat exposure was operationalized as a continuous variable and defined as the number of days that a mother was exposed to a mean daily temperature of > 26.6°C (A "hot day," equivalent to a mean daily temperature of > 80°F) during T1 or T2. Binary logistic regression was used to investigate the relationship between maternal heat exposure and miscarriage. RESULTS: A total of 105/3477 pregnancies included in our analysis ended in miscarriage (3.0%). Each additional hot day during T1 was associated with a 26% higher odds of miscarriage (odds ratio: 1.26; 95% confidence interval: 1.15-1.38). No significant associations were observed between maternal heat exposure during T2 and the odds of miscarriage (odds ratio: 0.94, 95% confidence interval: 0.73-1.20). The relationship between maternal heat exposure during T1 and the odds of miscarriage was J-shaped. CONCLUSION: There is a clear relationship between maternal heat exposure during the month preceding conception and miscarriage in our sub-Saharan African setting. Given the lack of feasible strategies to reduce pregnancy loss associated with prevailing high temperatures in sub-Saharan Africa, progressive climate change will likely exacerbate existing challenges for women's reproductive health in this region.

RESUMO

Background and Objectives: Miscarriage is a complication that is influenced by many risk factors that have been reported in different studies and that vary among countries. Despite the influence of various known risk factors for miscarriage, 30% to 50% of miscarriages are from unidentified causes. The aim of this study is to determine the prevalence of miscarriages in Jordan and the associated risk factors. Materials and Methods: A cross-sectional online survey was conducted in Jordan among married women to investigate the prevalence of miscarriages and identify potential risk factors. Results: Women (n = 704) were surveyed, and 17.9% reported a history of miscarriage. The identified risk factors were being an active smoker during pregnancy, having more than four children, having a family history of miscarriage, having fertility problems, receiving medical assistance for conception, and traveling by air during pregnancy. Conclusions: The results suggest that there are both modifiable and non-modifiable risk factors for miscarriages in Jordan and that a proportion of these may be preventable. The findings can be used to enhance patient awareness and inform policy development to decrease the incidence of miscarriage in the country.

RESUMO

BACKGROUND: Vaccination constitutes an attractive control measure for hepatitis E virus (HEV), a major cause of maternal and perinatal mortality globally. Analysis of pregnant participants in an effectiveness trial of the HEV vaccine HEV239 showed possible HEV239-associated fetal losses. We aimed to conduct a detailed analysis of this safety signal. METHODS: In a double-blind, cluster-randomised trial, 67 villages in Matlab, Bangladesh, were randomly allocated (1:1) to two vaccine groups, in which non-pregnant women aged 16-39 years received either HEV239 (HEV239 group) or Hepa-B (a hepatitis B vaccine; control group). We implemented weekly surveillance for pregnancy detection, and follow-up of pregnancies once every 2 weeks, using physician-confirmed diagnoses to evaluate fetal loss outcomes (miscarriage [spontaneous abortion], stillbirth, and elective termination). Data from a parallel system of reproductive health surveillance in Matlab were used to clarify study diagnoses when necessary. Miscarriage was assessed only among participants whose first positive pregnancy test and vaccination date (for whichever dose was closest to the date of last menstrual period [LMP]) were before 20 weeks' gestation. We defined the following analysis periods of interest: from 90 days before the LMP until the pregnancy outcome (the proximal period); from the LMP date until the pregnancy outcome (the pregnancy period); from 90 days before the LMP until the LMP date (90 days pre-LMP period); and from enrolment until 90 days before the LMP (the distal period). Both Poisson and Cox regression models were used to assess the associations between receipt of HEV239 and fetal loss outcomes. The trial was registered with ClinicalTrials.gov (NCT02759991). FINDINGS: Among the 19 460 non-pregnant participants enrolled in the trial, 5011 were identified as having pregnancies within 2 years following vaccination and met the criteria for analysis (2407 in the HEV239 group and 2604 in the control group). Among participants vaccinated in the proximal period and evaluated for miscarriage, miscarriage occurred in 54 (8·9%) of 607 in the HEV239 group and 32 (4·5%) of 719 in the control group (adjusted relative risk [aRR] 2·0 [95% CI 1·3-3·1], p=0·0009). Similarly, the risk of miscarriages was increased in the HEV239 group versus the control group among participants inadvertently vaccinated during pregnancy (22 [10·5%] miscarriages among 209 participants in the HEV239 group vs 14 [5·3%] of 266 in the control group; aRR 2·1 [95% CI 1·1-4·1], p=0·036) and among those vaccinated within 90 days pre-LMP (32 [8·0%] of 398 vs 18 [4·0%] of 453; 1·9 [1·1-3·2], p=0·013). No increased risk of miscarriage was observed in those who received HEV239 in the distal period (93 [5·6%] of 1647 vs 80 [4·5%] of 1773; 1·3 [0·8-1·9], p=0·295). Stillbirth and elective termination showed no increased risk among women administered HEV239 versus those administered Hepa-B in any of the analysis periods. INTERPRETATION: HEV239 given shortly before or during pregnancy was associated with an elevated risk of miscarriage. This association poses a possible safety concern for programmatic use of HEV239 in women of childbearing age. FUNDING: Research Council of Norway and Innovax.

RESUMO

OBJECTIVE: Given Iran's recent shift towards pronatalist population policies, concerns have arisen regarding the potential increase in abortion rates. This review study examines the trends of (medical), intentional (illegal), and spontaneous abortions in Iran over the past two decades, as well as the factors that have contributed to these trends. METHODS: This paper reviewed research articles published between 2005 and 2022 on abortion in Iran. The study employed the PRISMA checklist for systematic reviews. Articles were searched from international (Google Scholar, PubMed, Science Direct, and Web of Science) and national databases (Magiran, Medlib, SID). Once the eligibility criteria were applied, 42 records were included from the initial 349 records. RESULTS: Abortion is influenced by a variety of socioeconomic and cultural factors and the availability of family planning services. Factors that contribute to unintended pregnancy include attitudes toward abortion, knowledge about reproductive health, access to reproductive health services, and fertility desires, among others. In addition to health and medical factors, consanguineous marriage plays an important role in spontaneous and therapeutic abortion. A higher number of illegal abortions were reported by women from more privileged socioeconomic classes. In comparison, a higher number of medical and spontaneous abortions were reported by women from less privileged socioeconomic classes. CONCLUSION: Iranian policymakers are concerned about the declining fertility rate and have turned to pronatalist policies. From a demographic standpoint, this seems to be a reasonable approach. However, the new population policies, particularly, the Family Protection and Young Population Law, along with creating limitations in access to reproductive health services and prenatal screening tests as well as stricter abortion law could potentially lead to an increase in various types of abortions and their associated consequences.

RESUMO

Screening for polycystic ovary syndrome (PCOS) in antenatal care is inadequate, largely owing to the lack of clarity around whether PCOS is an independent risk factor for pregnancy complications. This systematic review and meta-analysis include 104 studies and 106,690 pregnancies in women with and without PCOS from inception until 13th July 2022. We report that women with PCOS are younger and have higher body mass index (BMI) around conception and have greater gestational weight gain. The odds of miscarriage, gestational diabetes mellitus, gestational hypertension, pre-eclampsia and cesarean section are higher in women with PCOS. The increased odds of adverse outcomes in PCOS remain significant when age and BMI are matched and when analyses are restricted to high-quality studies. This work informed the recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome, emphasizing that PCOS status should be captured in all women who are planning to, or have recently become pregnant to facilitate prevention of adverse outcomes and improve pregnancy outcomes.

RESUMO

Data on the use of golimumab (GLM) during pregnancy are limited. This study evaluated pregnancy outcomes in women treated with GLM during pregnancy. Cumulative data on GLM-exposed pregnancies from the Company's global safety database (GSD) are summarized. Cases were medically confirmed maternal exposures to GLM during pregnancy or within 3 months prior to conception with a reported pregnancy outcome. Pregnancy outcomes (e.g., live births) and congenital anomalies in prospectively reported cases (i.e., pregnancy outcome not known when first reported to the company) are presented in a descriptive manner. As of May 31, 2022, 261 prospectively reported pregnancies exposed to GLM were reported in the GSD: 214 (82.0%) live births (including six sets of twins), 31 (11.9%) spontaneous abortions (including one set of twins), 13 (5.0%) induced/elective abortions, 2 (0.8%) reported intrauterine death/still birth, and 1 (0.4%) fetal adverse event in an ongoing pregnancy. The majority of pregnancies had exposure to GLM at least in the first trimester of pregnancy. In total, seven congenital anomalies (7/261; 2.7%) were reported. Of these seven congenital anomalies, five were considered major according to EUROCAT classification version 1.4. Among the five prospectively reported congenital anomalies noted in live births (5/214; 2.3%), four were classified as major (4/214; 1.8%). The rates of adverse pregnancy outcomes and major congenital anomalies in prospectively reported pregnancy cases with exposure to GLM in the Company's GSD were consistent with published background rates for the general population.

RESUMO

BACKGROUND: Adverse pregnancy outcomes, including abortions, miscarriages and stillbirths, are common in developing countries such as Zimbabwe. OBJECTIVE: To determine the trends and factors associated with adverse pregnancy outcomes. METHODS: This article is a secondary data analysis of three repeated cross-sectional Zimbabwe Demographic and Health Surveys to assess adverse pregnancy outcomes among women of reproductive age (15 - 49 years old) who fell pregnant during the study period. Bivariate and multivariable logistic regression models were applied to the 2015 dataset to determine factors associated with adverse pregnancy outcomes. RESULTS: There was an overall increase in reported adverse pregnancy outcomes (stillbirths, miscarriages and abortions) from 2005 to 2015. The percentage of women who experienced adverse pregnancy outcomes among those who fell pregnant in the 5 years preceding each survey rose from 13.4% in 2005 to 13.8% in 2010, followed by a sharp increase to 16.3% in 2015. The multivariable model, belonging to the 35 - 49-year age group, was associated with almost a twofold increased odds of experiencing an adverse pregnancy outcome (adjusted odds ratio (aOR) 2.11, 95% confidence interval (CI) 1.35 - 3.31, p=0.001). Women currently married/in a union (aOR 4.69, 95% CI 2.64 - 8.34, p<0.001) or formerly married/in a union (aOR 3.56, 95% CI 1.89 - 6.69, p=0.001) had higher odds of experiencing an adverse pregnancy outcome. Not belonging to any religion or being a traditionalist or Muslim decreased the odds of experiencing an adverse pregnancy outcome (aOR 0.58, 95% CI 0.42 - 0.80, p=0.001). Women from Harare (aOR 1.56, 95% CI 1.05 - 2.32, p=0.027), Mashonaland West (aOR 1.59, 95% CI 1.08 - 2.36, p=0.027) and Mashonaland Central (aOR 1.76, 95% CI 1.15 - 2.69, p=0.009) provinces had higher odds of experiencing adverse pregnancy outcomes than those from Bulawayo Province. Women who gave birth for the first time at ≥25 years of age (aOR 3.08, 95% CI 2.27 - 4.16, p<0.001) had higher odds of experiencing adverse pregnancy outcomes. Women who delivered 2 - 4 children (aOR 0.75, 95% CI 0.59 - 0.95, p=0.018) or ≥5 children (aOR 0.51, 95% CI 0.36 - 0.72, p<0.001) were less likely to experience adverse pregnancy outcomes. CONCLUSION: Trends showed an increase in the proportion of women experiencing adverse pregnancy outcomes in Zimbabwe from 2005 to 2015. Advanced maternal age, marriage, lack of religion and living in Harare, Mashonaland Central or Mashonaland West were associated with adverse pregnancy outcomes. There is a need to reduce these outcomes through integration of social issues into maternal health programmes, as well as ensuring accessibility and availability of comprehensive reproductive health services that target high-risk groups such as women aged 35 - 49 years.

RESUMO

OBJECTIVES: The primary objective of this prospective cohort study was to assess the usefulness of a predefined multidisciplinary care pathway-based management on pregnancy outcome(s) in women with SLE who already had at least one adverse obstetric outcome(s). METHODS: Between March 2010 and March 2023, all consecutive, consenting women with SLE who already had at least one previous adverse obstetric outcome (preterm labour, pre-eclampsia, termination of pregnancy, miscarriage, intrauterine growth retardation (IUGR), preterm birth, low birth weight (LBW), intrauterine death (IUD) or stillbirth] were prospectively screened and counselled. The protocol comprised preconception and post-natal drug and disease status review, periodic ante-natal visits for the monitoring of pregnancy and drug and disease status review and post-natal drug and disease status review and contraception advice. Therapeutic changes were made as necessary at each visit. RESULTS: A total of 213 women were screened and 197 women (age, 28 ± 6.34 years) were enrolled who had 226 pregnancies. Previous poor obstetric outcomes were miscarriage(s), 186; termination of pregnancy, 4; preterm labour, 51; IUGR, 36; IUD or stillbirth, 16; low birth weight (LBW), 44 and pre-eclampsia, 4. Seventy-seven (39%) women had secondary APS and 37 (19%) had a history of lupus nephritis. There were 194/226 (86%) live births [40 LBW (18%); caesarean section in 101 (45%)]. Thirty pregnancies culminated in miscarriages and 2 in IUDs (14%). Sixty-eight patients (30%) experienced lupus flare during pregnancy (36 mild, 20 moderate and 8 severe). CONCLUSION: Our experience underscores the usefulness of a predefined multidisciplinary care pathway-based management for improving pregnancy outcomes in women with SLE who had previous adverse outcomes. Key Points • In women with SLE who had previous adverse obstetric outcome(s) a risk of poor outcome in subsequent pregnancy remains. • Good pregnancy outcomes in these women could be achieved by predefined  multidisciplinary care pathways focussed on addressing all relevant issues. • Improved access to rheumatology services and collaboration between rheumatologists and obstetricians is key to improving outcomes in SLE pregnancies.

RESUMO

RESEARCH QUESTION: Is low serum 25-hydroxyvitamin D (25(OH)D) associated with an increased risk of miscarriage in women who presented with threatened miscarriage to the Early Pregnancy Assessment Clinic (EPAC)? DESIGN: This was a secondary retrospective analysis using archived serum samples from a randomized, double-blind, placebo-controlled trial. Stored serum samples from 371 women presenting to the EPAC with threatened miscarriage during the first trimester were assayed for 25(OH)D by liquid chromatography-mass spectrometry. RESULTS: The overall miscarriage rate was 45/371 (12.1%) in the whole cohort. After grouping vitamin D insufficiency and vitamin D sufficiency together into a 'non-deficient' group and excluding participants who underwent termination of pregnancy, there was no difference in the miscarriage rate between those who were vitamin D deficient compared with those who were not (25/205, 12.2% versus 20/157, 12.7%, P= 0.877, odds ratio 0.951, 95% CI 0.507-1.784). When analysed according to the number of gestational weeks, the miscarriage rate was significantly higher in the vitamin D non-deficient group than the vitamin D-deficient group in women who presented at 6 gestational weeks or earlier (13/33 [39.4%] versus 10/58 [17.2%], P= 0.019), but there were no statistically significant differences between the two groups presenting at later gestations. There was no difference in the vitamin D level in women who had a miscarriage compared with those who had a live birth (48 [37-57] versus 47 [37-58] nmol/l, P= 0.725 median [25th-75th percentile]). CONCLUSIONS: A low serum vitamin D concentration was not associated with an increased risk of miscarriage in women with threatened miscarriage presenting to the EPAC.

RESUMO

OBJECTIVE: Earlier studies have indicated a potential link between dilatation and curettage (D&C) and subsequent preterm delivery, possibly attributed to cervical damage. This study examines outcomes in pregnancies subsequent to first-trimester curettage with and without cervical dilatation. METHODS: A retrospective cohort study was conducted on women who conceived after undergoing curettage due to a first trimester pregnancy loss. Maternal and neonatal outcomes of the subsequent pregnancy were compared between two groups: women who underwent cervical dilatation before their curettage and those who had curettage without dilatation. The primary outcome assessed was the rate of preterm delivery at the subsequent pregnancy, and secondary outcomes included other adverse maternal and neonatal outcomes. Univariate analysis was performed, followed by multiple logistic regression models to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS: Among the 1087 women meeting the inclusion criteria during the study period, 852 (78.4 %) underwent first-trimester curettage with cervical dilatation, while 235 (21.6 %) opted for curettage only. No significant maternal or neonatal different outcomes were noted between the study groups, including preterm delivery (5.5 % vs. 3.5 %, p = 0.16), fertility treatments, placental complications, and mode of delivery. However, deliveries following D&C were associated with higher rates of small for gestational age neonates (7.6 % vs. 3.8 %, p = 0.04). Multivariate analysis revealed that cervical dilation before curettage was not significantly linked to preterm delivery [adjusted odds ratio 0.64 (0.33-1.26), p = 0.20]. CONCLUSION: The use of cervical dilatation during a curettage procedure for first trimester pregnancy loss, does not confer additional risk of preterm delivery. Further studies are needed to reinforce and validate these results.
