#1455 Pregnancy and related complications after kidney transplantation—a retrospective study

Abstract Background and Aims Background Within 2 to 3 weeks of a successful renal transplantation, the fertility of women in childbearing age improves; however, pregnancy after kidney transplantation is challenging and may be associated with serious maternal and fetal complications. Aims To study the prevalence of pregnancy and pregnancy related complication after kidney transplantation (KT). Method Retrospective cohort study conducted on 236 patients out of 3000 kidney transplant recipient who underwent renal transplantation (RT) at Mansoura Urology and Nephrology Centre between March 1976 and December 2019, divided into two groups, group I; 118 kidney transplant recipient who experienced pregnancy at any time after kidney transplantation and Group II; 118 kidney transplant recipients who didn`t experience pregnancy after renal transplantation, they were matched according to age, duration of renal transplantation and they are comparable in primary immunosuppressant drugs. All kidney recipients were reviewed for preoperative, operative, and post-operative details also we record maternal and fetal complication. Results Prevalence of pregnancy in our center is 191 pregnancies in 118 women who had underwent kidney transplantation between 1976 and 2019. We have found that the mean age of pregnancy between (26.27 ± 4.37-29.89 ± 4.6), the mean gestational age between (33.69 ± 6.4 – 33 ± 7.5) weeks, the live birth rate is 126 (66%). Preterm delivery rate in our study is 85 (44.5%), neonatal death 8 (4.1%), miscarriage 59 (30.9%), intrauterine fetal death 6 (3.1%) and birth defect 4 (2%). The prevalence rates of gestational hypertension is 87 (45.5%), pre-eclampsia 48 (25.1%), gestational diabetes 19 (9.9%), urinary tract infection 36 (18.8%), and graft rejection 8 (4.1%) during pregnancy. caesarean section is the most common method of delivery in our study 133 (69.6%). Conclusion The risk of maternal and fetal complications is still high in RT patients and requires multidisciplinary care. All should be considered in patient counseling and clinical decision making. So we recommend educating the transplanted patients to allow for outcome optimization and minimization of complications.

#1844 Pregnancy outcome among kidney transplant recipients

Abstract Background and Aims Background The possibility of a term pregnancy is one of the benefits of solid organ transplantation for women. The gonadal dysfunction, caused by the failure of the kidney or another organ, is reverted within a few months after normal graft function. Unplanned pregnancies in transplant recipients, however, may compromise graft function and survival, and may also risk unnecessary fetal exposure to immunosuppressive medications. Aims To study the prevalence of pregnancy and pregnancy related complication after kidney transplantation (KT). Method Retrospective cohort study conducted on 236 patients out of 3000 kidney transplant recipient who underwent renal transplantation (RT) at Mansoura Urology and Nephrology Centre between March 1976 and December 2019. divided into group I; 118 kidney transplant female's recipient experienced pregnancy at any time after kidney transplant and group II; 118 kidney transplant female's recipients who didn`t experience pregnancy after renal transplantation, they were matched according to age and duration of renal transplantation and comparable in primary immunosuppressant drugs. all kidney recipients were reviewed for preoperative & operative and post-operative details also we record maternal and fetal complication.

Kidney transplant recipients who aged more than or equal to 30 years at time of pregnancy are at higher risk for having non live-birth outcome (OR: 3.2, p value: 0.05). Proteinuria more than or equal to 0.5 g/day before pregnancy is a significant risk factor for having non live-birth outcome (OR: 4.7, p value: 0.009). Also, proteinuria ≥0.5 g/day during pregnancy is associated with increases risk for non-live-birth (OR: 10.2, p value: 0.013). Gesatational hypertension is associated with increases risk for non-live-birth (OR: 8.3, p value: 0.010).Preeclampsia is associated with increases risk for non-live-birth (OR: 4.6, p value: 0.005). Conclusion Although the outcome of live births is favourable, the risks of maternal and fetal complications are high in kidney transplant recipients including pregnancy-induced hypertension, increased rates of preeclampsia, gestational diabetes, and caesarean section rates. The risk of miscarriage, prematurity, and low birth rate is also high.

THBS1 regulates decidualization in URSA.

Inappropriate endometrial stromal decidualization has been implied as an important reason of many pregnancy-related complications, such as unexplained recurrent spontaneous abortion (URSA), preeclampsia and intrauterine growth restriction. Here, we observed that thrombospondin-1 (THBS1), an adhesive glycoprotein, was significantly downregulated in endometrial decidual cells from patients with URSA. The immortalized human endometrial stromal cell line T-HESC was used to investigate the possible THBS1-mediated regulation of decidualization. In vitro experiments found that the expression level of THBS1 increased with the normal decidualization process. Knockdown of THBS1 could decrease the expression levels of prolactin (PRL) and insulin-like growth factor binding protein-1 (IGFBP1), two acknowledged human decidualization markers. Whereas, THBS1 overexpression could reverse these effects. The RNA sequencing results demonstrated that the extracellular regulated protein kinases (ERK) signaling pathway was potentially affected by the knockdown of THBS1. And we further confirmed that the regulation of THBS1 on decidualization was achieved through the ERK signaling pathway by the treatment of inhibitors. Moreover, knockdown of THBS1 in pregnant mice could impair decidualization and result in an increased fetus resorption rate. Altogether, our study demonstrated a crucial role of THBS1 in the pathophysiological process of URSA and provided some new insights into the research of pregnancy-related complications.

Fertility and pregnancy complications in female orthopaedic surgeons.

While the number of female medical graduates continues to increase, only a few pursue an orthopaedic career. This is related to challenges regarding pregnancy and the peripartum period during orthopaedic training. To evaluate fertility, pregnancy-related complications and attitudes towards female orthopaedic surgeons in Israel. An electronic anonymous 34-question electronic web-based survey was sent to all Israeli female orthopaedic surgeons. Participation was voluntary. Questions were formulated to determine demographics, obstetrics medical history, teratogenic exposure, medical leave and breastfeeding parameters along with attitude towards pregnancy. Twenty-six orthopaedic surgeons complied with the survey, 68% of all registered female orthopaedic surgeons. Participants age was 39.5 (±8.8). The average number of children for a female orthopaedic surgeon was 2.2 (±1.4), with an average of 1.3 (±1.1) deliveries during residency. The average age for a first child was 31.1 (±3.7) years. Four surgeons required fertility treatments and six had abortions. Thirty-eight per cent experienced pregnancy complications. Most surgeons were exposed to radiation and bone cement during pregnancy. The average duration of maternity leave was 19.4 (±9.9) weeks and return to work was associated with cessation of breastfeeding. Seventy-six per cent of surgeons felt that pregnancy had negatively influenced their training, and 12% reported negative attitudes from colleagues and supervisors. Orthopaedic surgeons in Israel experience a delay in childbirth and higher rates of pregnancy complications. Most feel that their training is harmed by pregnancy. Programme directors should design a personalized support programme for female surgeons during pregnancy and the peripartum period.

Pregnancy related complications in women with hypertrophic cardiomyopathy: a nationwide population-based cohort study

BackgroundThe impact of hypertrophic cardiomyopathy (HCM) on cardiovascular and obstetrical outcomes in pregnant women remains unclear, particularly in Asian populations. This study aimed to evaluate the maternal cardiovascular and obstetrical outcomes in Korean women with HCM.MethodsUsing data from the Korean National Health Insurance Service database, we identified women who gave birth via cesarean section or vaginal delivery after being diagnosed with HCM between 2006 and 2019. Maternal cardiovascular and obstetrical outcomes were assessed based on the trimester of pregnancy.ResultsThis study included 122 women and 158 pregnancies. No maternal deaths were noted; however, 21 cardiovascular events, such as hospital admission for cardiac problems, including heart failure and atrial fibrillation (AF), new-onset AF or ventricular tachycardia (VT) occurred in 14 pregnancies (8.8%). Cardiac events occurred throughout pregnancy with a higher occurrence in the third trimester. Cesarean sections were performed in 49.3% of the cases, and all cardiovascular outcomes occurring after delivery were observed in patients who had undergone cesarean sections. Seven cases involved preterm delivery, and two of these cases were accompanied by cardiac events, specifically AF. Pre-existing arrhythmia (AF: odds ratio (OR): 7.44, 95% confidence interval (CI): 2.61–21.21, P < 0.001; VT: OR: 31.61, 95% CI: 5.85–172.77, P < 0.001) was identified as a predictor for composite outcomes of cardiovascular events or preterm delivery.ConclusionsMost pregnant women with HCM were well-tolerated. However, cardiovascular complications could occur in some patients. Therefore, planned delivery may be necessary for selected patients, especially the women with pre-existing arrhythmias.

“A Study to Assess the Effectiveness of Video Assisted Teaching Programme on Knowledge Regarding Evidence Based Practice in Labour Practices among Final Year Bsc Nursing Students at Selected College of Nursing, Mysuru.”

Pregnancy-related complications are the second global leading cause of death among women of reproductive age. In 2015, approximately 3,03,000 maternal deaths occurred worldwide, most of which could have been prevented. The application of evidence-based practices in labour at maternity units has shown changes in pregnancy and labour outcomes, hence the researcher undertaken this study. Methods: The research approach adopted for the present study was pre-experimental one group pre-test post-test research design. The 60 samples were selected by nonprobability purposive sampling technique. The self-structured knowledge questionnaires were used to gather the data. The data was analyzed by using the descriptive and inferential statistics. Result: In the pre-test the overall mean percentage of knowledge score was 50.66% with mean and SD of 15.20±1.48 and in post-test the mean percentage of post-test knowledge was 91.76% with mean and SD of 27.53±1.17. The mean difference was 12.33 with SD of 1.90. The calculated paired ‘t’ test value was 50.24 at the degree of freedom 59, the p value was 0.0001. There was no significant association between the demographic variables with pretest knowledge score. Interpretation and Conclusion: The video assisted teaching program was effective in enhancing the knowledge of the samples regarding evidence-based practices in labor. The study recommends to conduct a study on use of evidence-based practices among staff nurses in labor room.

The Molecular Basis of the Augmented Cardiovascular Risk in Offspring of Mothers with Hypertensive Disorders of Pregnancy.

The review examines the impact of maternal preeclampsia (PE) on the cardiometabolic and cardiovascular health of offspring. PE, a hypertensive disorder of pregnancy, is responsible for 2 to 8% of pregnancy-related complications. It significantly contributes to adverse outcomes for their infants, affecting the time of birth, the birth weight, and cardiometabolic risk factors such as blood pressure, body mass index (BMI), abdominal obesity, lipid profiles, glucose, and insulin. Exposure to PE in utero predisposes offspring to an increased risk of cardiometabolic diseases (CMD) and cardiovascular diseases (CVD) through mechanisms that are not fully understood. The incidence of CMD and CVD is constantly increasing, whereas CVD is the main cause of morbidity and mortality globally. A complex interplay of genes, environment, and developmental programming is a plausible explanation for the development of endothelial dysfunction, which leads to atherosclerosis and CVD. The underlying molecular mechanisms are angiogenic imbalance, inflammation, alterations in the renin-angiotensin-aldosterone system (RAAS), endothelium-derived components, serotonin dysregulation, oxidative stress, and activation of both the hypothalamic-pituitary-adrenal axis and hypothalamic-pituitary-gonadal axis. Moreover, the potential role of epigenetic factors, such as DNA methylation and microRNAs as mediators of these effects is emphasized, suggesting avenues for future research and therapeutic interventions.

Pregnancy-related complications in patients with endometriosis in different stages

BackgroundEndometriosis is one of the most common and costly diseases among women. This study was carried out to investigate pregnancy outcomes in women with endometriosis because of the high prevalence of endometriosis in reproductive ages and its effect on pregnancy-related complications outcomes.MethodsThis was a cross-sectional study performed on 379 pregnant women with endometriosis who were referred to the endometriosis clinic of the Avicenna Infertility Treatment Center from 2014 to 2020. Maternal and neonatal outcomes were assessed for the endometriosis group and healthy mothers. The group with endometriosis was further divided into two groups: those who underwent surgery and those who either received medication alone or were left untreated before becoming pregnant. The analysis of the data was done using SPSS 18.ResultsThe mean age of the patients was 33.65 ± 7.9 years. The frequency of endometriosis stage (P = 0.622) and surgery (P = 0.400) in different age groups were not statistically significant. The highest rates of RIF and infertility were in stages 3 (N = 46, 17.2%) (P = 0.067), and 4 (N = 129, 48.3%) (P = 0.073), respectively, but these differences were not statistically different, and the highest rate of pregnancy with ART/spontaneous pregnancy was observed in stage 4 without significant differences (P = 0.259). Besides, the frequency of clinical/ectopic pregnancy and cesarean section was not statistically different across stages (P > 0.05). There is no significant relationship between endometriosis surgery and infertility (P = 0.089) and RIF (P = 0.232). Most of the people who had endometriosis surgery with assisted reproductive methods got pregnant, and this relationship was statistically significant (P = 0.002) in which 77.1% (N = 138) of ART and 63% (N = 264) of spontaneous pregnancies were reported in patients with endometriosis surgery. The rate of live births (59.4%) was not statistically significant for different endometriosis stages (P = 0.638). There was no stillbirth or neonatal death in this study. All cases with preeclampsia (N = 5) were reported in stage 4. 66.7% (N = 8) of the preterm labor was in stage 4 and 33.3% (N = 4) was in stage 3 (P = 0.005). Antepartum bleeding, antepartum hospital admission, preterm labor, gestational diabetes, gestational hypertension, abortion, placental complications and NICU admission were higher in stage 4, but this difference had no statistical difference.ConclusionEndometriosis is significantly correlated with infertility. The highest rates of RIF and infertility are observed in stages 3 and 4 of endometriosis. The rate of pregnancy with ART/spontaneous pregnancy, preterm labor, preeclampsia and pregnancy-related complications is higher in stage 4. Most of the people who had endometriosis surgery with assisted reproductive methods got significantly pregnant. Clinical/ectopic pregnancy, cesarean sections, and live birth were not affected by the endometriosis stages.

The prevention of adverse pregnancy outcomes by periodontal treatment during pregnancy (PROBE) intervention study-A controlled intervention study: Protocol paper.

Pregnancy increases the risk of periodontitis due to the increase in progesterone and estrogen. Moreover, periodontitis during pregnancy is associated with development of pregnancy and birth related complications. The aim of this study is to determine, whether periodontal treatment during pregnancy can reduce systemic inflammation and lower the risk of adverse pregnancy and birth related outcomes. The PROBE study is a non-randomized controlled intervention study conducted among 600 pregnant women with periodontitis. The women will be recruited among all pregnant women at two Danish hospitals in Region Zealand during their nuchal translucency scan and will subsequently be screened for periodontitis. The intervention group includes 300 pregnant women, who will be offered state-of-the-art periodontal treatment during pregnancy. The control group includes additional 300 pregnant women, who will be offered periodontal treatment after giving birth. Outcome measures include periodontal measures, inflammatory, hormonal and glycaemic markers as well as the prevalence of preterm birth risk, low birth weight and risk markers of gestational diabetes mellitus (GDM) and preeclampsia that will be collected from all screened women and further during pregnancy week 20 and pregnancy week 35 for women enrolled in the intervention. The study's findings will be published in peer reviewed journals and disseminated at national and international conferences and through social media. The PROBE study is designed to provide important new knowledge as to whether periodontal treatment during pregnancy can reduce the prevalence of complications related to pregnancy and birth. The study was registered on clinicaltrials.gov (NCT06110143).

A Microphysiological Model to Mimic the Placental Remodeling during Early Stage of Pregnancy under Hypoxia-Induced Trophoblast Invasion.

Placental trophoblast invasion is critical for establishing the maternal-fetal interface, yet the mechanisms driving trophoblast-induced maternal arterial remodeling remain elusive. To address this gap, we developed a three-dimensional microfluidic placenta-on-chip model that mimics early pregnancy placentation in a hypoxic environment. By studying human umbilical vein endothelial cells (HUVECs) under oxygen-deprived conditions upon trophoblast invasion, we observed significant HUVEC artery remodeling, suggesting the critical role of hypoxia in placentation. In particular, we found that trophoblasts secrete matrix metalloproteinase (MMP) proteins under hypoxic conditions, which contribute to arterial remodeling by the degradation of extracellular matrix components. This MMP-mediated remodeling is critical for facilitating trophoblast invasion and proper establishment of the maternal-fetal interface. In addition, our platform allows real-time monitoring of HUVEC vessel contraction during trophoblast interaction, providing valuable insights into the dynamic interplay between trophoblasts and maternal vasculature. Collectively, our findings highlight the importance of MMP-mediated arterial remodeling in placental development and underscore the potential of our platform to study pregnancy-related complications and evaluate therapeutic interventions.

Navigating geographical disparities: access to obstetric hospitals in maternity care deserts and across the United States

BackgroundAccess to maternity care in the U.S. remains inequitable, impacting over two million women in maternity care “deserts." Living in these areas, exacerbated by hospital closures and workforce shortages, heightens the risks of pregnancy-related complications, particularly in rural regions. This study investigates travel distances and time to obstetric hospitals, emphasizing disparities faced by those in maternity care deserts and rural areas, while also exploring variances across races and ethnicities.MethodsThe research adopted a retrospective secondary data analysis, utilizing the American Hospital Association and Centers for Medicaid and Medicare Provider of Services Files to classify obstetric hospitals. The study population included census tract estimates of birthing individuals sourced from the U.S. Census Bureau's 2017-2021 American Community Survey. Using ArcGIS Pro Network Analyst, drive time and distance calculations to the nearest obstetric hospital were conducted. Furthermore, Hot Spot Analysis was employed to identify areas displaying significant spatial clusters of high and low travel distances.ResultsThe mean travel distance and time to the nearest obstetric facility was 8.3 miles and 14.1 minutes. The mean travel distance for maternity care deserts and rural counties was 28.1 and 17.3 miles, respectively. While birthing people living in rural maternity care deserts had the highest average travel distance overall (33.4 miles), those living in urban maternity care deserts also experienced inequities in travel distance (25.0 miles). States with hotspots indicating significantly higher travel distances included: Montana, North Dakota, South Dakota, and Nebraska. Census tracts where the predominant race is American Indian/Alaska Native (AIAN) had the highest travel distance and time compared to those of all other predominant races/ethnicities.ConclusionsOur study revealed significant disparities in obstetric hospital access, especially affecting birthing individuals in maternity care deserts, rural counties, and communities predominantly composed of AIAN individuals, resulting in extended travel distances and times. To rectify these inequities, sustained investment in the obstetric workforce and implementation of innovative programs are imperative, specifically targeting improved access in maternity care deserts as a priority area within healthcare policy and practice.

The safety and efficacy of tumor necrosis factor-alpha inhibitor on pregnancy outcomes in patients with unexplained recurrent miscarriage

ObjectivesAlthough tumor necrosis factor-alpha inhibitor (TNFi) treatment may improve pregnancy outcomes in unexplained recurrent miscarriage (URM) patients, evidence for its efficacy and safety is still insufficient. The goal of this study was to evaluate the efficacy and safety of TNFi on pregnancy outcomes in patients with URM. MethodsThis retrospective study was conducted at a single institution in China, involving 121 patients treated with TNFi for URM from 2019 to 2022. Patients enrolled were divided into treatment group (receiving TNFi and heparin therapy) and control group (receiving heparin therapy). The outcome variables were the 24-week live birth rate, miscarriage rate, ectopic pregnancy rate, neonatal outcomes, and adverse events. ResultsIn our study, patients receiving TNFi treatment exhibited a significant increase in live birth rates, achieving 71.2 % compared to the 50.9 % observed in the control group (OR 2.507, 95 % CI: 1.127–5.579). Concurrently, there was a discernible reduction in the miscarriage rate within the TNFi-treated group, marking 24.2 %, in contrast to 43.6 % in the control group (OR 0.387, 95 % CI: 0.170–0.884). Subgroup analyses further illuminated that those under the age of 35 benefitted remarkably from TNFi treatment, with live birth rates soaring to 62.5 % (OR 2.525, 95 % CI: 1.041–6.125). For patients with a history of two miscarriages, the TNFi regimen significantly augmented the live birth rate to 58.9 % (OR 3.044, 95 % CI: 1.039–8.921). Patients with a normal weight range registered a 58.4 % live birth rate post-TNFi treatment (OR 4.261, 95 % CI: 1.539–11.397). Notably, an evident interaction between BMI and TNFi treatment was identified, suggesting a potential modulatory role of BMI on the therapeutic efficacy of TNFi. About safety assessments, neither the TNFi-treated group nor the control manifested any significant disparities in liver function abnormalities, platelet count anomalies, or other pregnancy-related complications. ConclusionsTNFi, alongside basic therapy, notably enhances the live birth rate in URM patients under 35, with two prior miscarriages or a normal BMI, without increasing adverse event risk. Further prospective studies are essential to validate these observations.

Effect of probiotic administration during pregnancy on the functional diversity of the gut microbiota in healthy pregnant women.

Probiotics are considered beneficial to human health. There is limited understanding of how probiotic consumption during pregnancy affects the functional diversity of the gut microbiota. The aim of our study is to investigate the impact of probiotic consumption during pregnancy on the functional diversity of the gut microbiota. Our findings suggest that probiotic supplementation during pregnancy has a significant impact on functional metabolism. This could potentially open up new avenues for preventing various pregnancy-related complications. This also provides new insights into the effects of probiotic consumption during pregnancy on the gut microbiota and offers a convenient method for exploring the potential mechanisms underlying the impact of probiotics on the gut microbiota of pregnant women.

The effect of histo-blood group ABO system transferase (BGAT) on pregnancy related outcomes：A Mendelian randomization study

Protein level of Histo-Blood Group ABO System Transferase (BGAT) has been reported to be associated with cardiometabolic diseases. But its effect on pregnancy related outcomes still remains unclear. Here we conducted a two-sample Mendelian randomization (MR) study to ascertain the putative causal roles of protein levels of BGAT in pregnancy related outcomes. Cis-acting protein quantitative trait loci (pQTLs) robustly associated with protein level of BGAT (P < 5 ×10−8) were used as instruments to proxy the BGAT protein level (N = 35,559, data from deCODE), with two additional pQTL datasets from Fenland (N = 10,708) and INTERVAL (N = 3301) used as validation exposures. Ten pregnancy related diseases and complications were selected as outcomes. We observed that a higher protein level of BGAT showed a putative causal effect on venous complications and haemorrhoids in pregnancy (VH) (odds ratio [OR]=1.19, 95% confidence interval [95% CI]=1.12–1.27, colocalization probability=91%), which was validated by using pQTLs from Fenland and INTERVAL. The Mendelian randomization results further showed effects of the BGAT protein on gestational hypertension (GH) (OR=0.97, 95% CI=0.96–0.99), despite little colocalization evidence to support it. Sensitivity analyses, including proteome-wide Mendelian randomization of the cis-acting BGAT pQTLs, showed little evidence of horizontal pleiotropy. Correctively, our study prioritised BGAT as a putative causal protein for venous complications and haemorrhoids in pregnancy. Future epidemiology and clinical studies are needed to investigate whether BGAT can be considered as a drug target to prevent adverse pregnancy outcomes.

Associations of pentachlorophenol exposure during pregnancy with maternal and infant reproductive hormones based on a birth cohort

Pentachlorophenol (PCP), a typical environmental endocrine disruptor and a new persistent organic pollutant, has been extensively used as a pesticide worldwide. Although its use has been restricted for decades, PCP remains prevalent in both the environment and human bodies. Despite the known endocrine-disrupting and exogenous hormonal effects of PCP, few epidemiological studies examined such impact, especially among sensitive populations and during critical periods. Based on a prospective birth cohort in Wuhan, China, we collected maternal (first trimester; 13.0 ± 1.02 gestational weeks) and infant urine samples (1.16 ± 0.22 months postpartum) from 720 mother-infant pairs. We aimed to examine the association of PCP exposure during early pregnancy with maternal and infant urinary sex steroid hormones, including estrogens (estrone, E1; estradiol, E2; estriol, E3), progestogens (progesterone, P4; pregnenolone, P5; 17α-OH-Progesterone, 17OHP4; 17α-OH-Pregnenolone, 17OHP5), and androgens (testosterone, Testo; dihydrotestosterone, DHT; dehydroepiandrosterone, DHEA; androstenedione, A4). Additionally, gonadotropins [follicle-stimulating hormone (FSH) and luteinizing hormone (LH)] were measured in infant urine. Detection frequencies of all the sex steroid hormones in the maternal urine samples (>99 %) were higher than those in the infants' [most ≥80 %, except for E1 (3.36 %) and E2 (21.4 %)]. Maternal urinary PCP concentration was found to be significantly related with increased maternal sex steroid hormone concentrations; each interquartile increase in PCP concentration was positively related with percent change of the hormones (%Δ) ranging from 26.6 % to 48.5 %. On the other hand, maternal PCP exposure was associated with significantly increased P4 in male infants [%Δ (95 % confidence interval): 10.5 (0.56, 21.4)] but slightly decreased P4 in female infants [−11.9 (−21.8, 0.68)]. In addition, maternal PCP exposure was significantly associated with decreased FSH [%Δ (95 % CI): −9.90 (−17.0, −2.18)] and LH [−8.44 (−16.0, −0.19)] in the female infants, but not in the male infants. Sensitivity analyses, excluding infertility related treatment, pregnancy complications, preterm birth, or low birth weight, showed generally consistent results. Our findings implied that maternal/prenatal PCP exposure might disrupt the homeostasis of maternal and infant reproductive hormones. However, further studies are needed to confirm the findings.

The Need for Gynecological Ultrasound Examination on IUD Acceptors

Maternal Mortality Rate (MMR) signifies the number of women who perish due to pregnancy-related complications or their treatment per 100,000 live births, with septic shock emerging as a notable contributor. One such complication linked to septic shock is the rare but perilous translocation of intrauterine devices (IUDs), leading to potential uterine perforation. A recent case of maternal death underscored the urgency of prompt intervention in intraabdominal IUD translocations, with the delay stemming from the refusal of necessary surgical procedures. This tragic incident emphasizes the critical need for timely detection and management of IUD translocations to avert life-threatening complications. Integrating routine gynecological ultrasound examinations to assess uterine shape for prospective IUD acceptors and promoting informed consent through engagement with family members, community leaders, and policymakers is essential in mitigating the risk of maternal mortality associated with such complications.

E008 Review of rheumatology care for women of childbearing age

Abstract Background/Aims Autoimmune rheumatic diseases are frequently diagnosed in women of childbearing age. Managing these conditions during pregnancy is complex because commonly used disease-modifying antirheumatic drugs (DMARDs) can pose risks. Specialized care for this patient group is crucial, necessitating adherence to established rheumatology practice standards and British Society for Rheumatology (BSR) guidelines. Our main objective is to review management of childbearing age females with rheumatic diseases attending Basildon hospital as per BSR guidelines. Methods The data for this retrospective study was collected from the electronic records of female patients attending the rheumatology outpatient clinic at Basildon Hospital between September and December 2022. We reviewed age, the specific rheumatological diagnosis, disease duration, disease activity, current medications, and whether general advice or pregnancy-specific advice was provided. Results Out of the initial cohort of 63 female patients, 48 (76%) aged between 18-55 years were selected as women of childbearing age, The median age was 46 years, with 65% in the age groups of 31-50 years, 25% in group 51-55 years and 10% 18-30 years age group. 58% of patients had inflammatory arthritis, 18.7% had connective tissue disease, 18.7% had other conditions such as hypermobility, osteoarthritis, and regional pain syndrome, 2.3% were diagnosed with vasculitis and 2.3% with polymyalgia rheumatica. Breakdown of inflammatory arthritis patients revealed rheumatoid arthritis in 64%, psoriatic arthritis 15% and ankylosing spondylitis 12%. Axial spondyloarthropathy, palindromic rheumatism, and juvenile idiopathic arthritis, each accounted for 3%. Regarding prescribed medications, 66% of the individuals were on conventional DMARDs, biologics 24%, corticosteroids 6% and 4% were on other treatments. The DMARDs prescribed were methotrexate 27%, hydroxychloroquine 19%, sulfasalazine 13%, mycophenolate 3% and leflunomide 1%. The majority of patients had disease activity in remission or mild, each accounting for 23%. Moderate and severe disease activity were reported in 21% each of the audited sample. Patients received advice specifically related to pregnancy 29%, while 71% did not have documented pregnancy-related guidance. 70% of females of reproductive age received general advice. Conclusion The study highlights a gap in pregnancy-related advice among the childbearing age patients as only 29% received guidance on pregnancy. This underpins the need for proactive counselling and education for female patients in routine practice, work in partnership with obstetric teams, and primary care to reduce potential pregnancy related complications and improve outcomes.

Determinants of early antenatal care visits among women of reproductive age in Ghana: evidence from the recent Maternal Health Survey

BackgroundAntenatal care services play a crucial role in promoting positive pregnancy outcomes by facilitating the early identification of pregnancy risk factors and early diagnosis of pregnancy-related complications. This study aimed to assess the frequency and timing of ANC attendance of mothers in Ghana as well as determine the predictors of early ANC attendance.MethodsThe data for this study was extracted from the 2017 Ghana Maternal Health Survey (GMHS). The study population was women aged 15–49 years with a live birth or stillbirth in the 5 years preceding the survey. Data was analysed using STATA/SE version 17, using descriptive statistics and multiple binary logistic regression analysis.ResultsIt was found that 44.4% of the women obtained eight (8) + ANC visits. A majority of the women (66%) initiated ANC visits in the first trimester of pregnancy. Early ANC visit was significantly associated with age of the respondent, education, wealth index, religion, region and reason for first ANC visit. For instance, women between the ages of 25–29 years (aOR = 1.75, 95% CI: 1.31–2.33) had increased odds of early ANC visit compared to those aged 15–19 years. Women with higher education (aOR = 1.83, 95% CI: 1.27–2.64) were about twice as likely to initiate early ANC visits compared to those with no education. Also, women in the highest wealth index (aOR = 2.43, 95% CI: 1.83–3.23) were two times more likely to initiate early ANC visits compared to those in the lowest wealth index.ConclusionThis study has shown that a majority of women in Ghana start their first ANC visit during the first trimester of pregnancy. A considerable proportion of the women failed to meet the WHO’s recommendation of having a minimum of eight ANC visits throughout pregnancy. Early ANC visit was determined by socio-demographic factors. Going forward, it should be a priority for stakeholders to ensure that ANC services are accessible to all mothers in a timely manner.
