Spontaneous Miscarriage Research Articles

Reproductive and pregnancy control in Wilson disease patients in Spain.

Recommendations on pregnancy, lactation, and contraception in women with Wilson disease are briefly stated in international guidelines but are not entirely homogeneous. Data regarding the management of these special events among patients with Wilson disease in Spain are lacking. We used the Wilson Registry platform of the Spanish Association for the Study of the Liver to question patients on their reproductive and gestational lives. This was a multicentre ambispective study including adult women with Wilson disease in the Spanish Wilson Registry interviewed about their contraception, childbearing, pregnancy, and lactation experiences. Clinical and analytical data were extracted from the registry. The study included 92 women from 17 centres in Spain. Most (63%) reported having a previous pregnancy history. The rate of spontaneous miscarriages was 21.6%, mainly occurring in the first trimester and up to one third among undiagnosed patients. Most pregnant women received chelator therapy during pregnancy, but dose reduction was recommended in less than 10%. After delivery, artificial lactation predominated (60.3%) and its use was mainly based on physician's recommendations (68%). Up to 40% of the women included reported some concerns about their reproductive lives, mainly related to the potential drug toxicity to their children. Most of the patients considered the information given by specialists to be sufficient. Gestational management among women with Wilson disease in Spain was found to be highly heterogeneous and frequently different from what is described in international guidelines. Education on rare liver diseases should be a priority for scientific societies in order to homogenize patient follow-up and recommendations.

8319 Pituitary Apoplexy Leads to the Spontaneous Resolution of Hypercortisolism Secondary to Cushing Disease: A Clinical Case

Abstract Disclosure: N. Sweis: None. J. Sanchez Perez: None. M. Fariduddin: None. R.M. Sargis: None. D.J. Toft: None. S. Reutrakul: None. Background: Pituitary apoplexy is a potentially fatal condition involving the infarction or hemorrhage of the pituitary gland. Rarely, it can occur in the setting of an ACTH-secreting pituitary adenoma. Clinical Case: A 27-year-old female with a past medical history of obesity, spontaneous miscarriages, and amenorrhea presented to the ER with an acute onset frontal headache of throbbing quality, associated with nausea and vomiting. The headache began two days prior, rapidly intensified, and did not improve with oral acetaminophen. CT of the head revealed an enlarged pituitary gland, while neurovascular imaging showed no abnormalities. Her neurologic examination was normal. She denied visual changes, photophobia, neck rigidity, fevers, chills, or recent infections. Furthermore, she endorsed a weight gain of about 40 pounds over the past year despite no change in dietary habits. This was accompanied by amenorrhea, hair thinning, itchy comedonal acne, hirsutism, and a loss of libido. Her physical examination was remarkable for the presence of cushingoid features including violaceous abdominal striae, facial acne, moon facies, a dorsal fat pad, and acanthosis nigricans around the neck and axillae. Pituitary MRI with and without contrast showed an enlarged sellar and suprasellar macroadenoma measuring approximately 2.1x1.4x1.2 cm abutting the optic chiasm. The visualized lesion contained hemorrhagic products, suggesting pituitary apoplexy. Biochemical testing on admission included a low morning plasma cortisol of 6.5 ug/dL (ref. range: 6.7-22.6 ug/dL), a 24-hour urine free cortisol of 12.0 (<=45.0 ug/24 hour), and an elevated ACTH of 145.0 pg/mL (7.2 - 63.3 pg/mL). A1c was 5.8% (<5.7%). Serum levels of prolactin, IGF1, GH, LH, FSH, TSH, Free T4, estradiol, total and bioavailable testosterone were within normal limits. She was evaluated with an ACTH stimulation test, which showed a morning cortisol level of 1.2 ug/dL at baseline, lower from prior. Cortisol levels were adequately increased at 19.6 ug/dL and 22.6 ug/dL, 30 and 60 minutes after the administration of Cosyntropin 250 mcg, respectively (>=18 ug/dL after 30-60 mins). The level of ACTH at the time was also decreased to 76.6 pg/mL. The patient was therefore started on steroid replacement therapy with hydrocortisone and later underwent transsphenoidal resection of the pituitary mass without complications. Histopathological examination of the resected mass showed pituitary adenoma cells with diffuse weak to moderate ACTH staining, most consistent with a sparsely granulated corticotroph pituitary adenoma. Conclusion: We report an interesting case of Cushing disease that spontaneously resolved after pituitary apoplexy. Our case underlines the importance of close monitoring of such patients who may rapidly undergo a period of adrenal insufficiency after hypercortisolism. Presentation: 6/3/2024

12238 A Case Of Drug-induced Vasculitis

Abstract Disclosure: C. Javier: None. M.H. Horani: None. Title: A Case of Drug-Induced VasculitisChristian Javier, DOMohamad Horani, MD Introduction: Graves’ disease is commonly managed with thionamides. These have rare but serious complications of drug-induced lupus-like syndrome and vasculitis. In patients who present with rheumatologic and inflammatory findings, it is important to consider the possibility of these complications . Case Presentation: We present a 30-year-old female with Graves disease, asthma, and hypertension with concerns for cough, body aches, fatigue, bilateral flank pain, erythema, itching and burning of the hands, in the setting of recent spontaneous miscarriage. She was diagnosed with Graves’ nearly 2 years ago and was started on methimazole, but discontinued due to adverse effects of the medication. She was then started on PTU. The patient had a seizure, and head CT revealed a left-sided 4 cm brain mass in the left frontal lobe. The patient was admitted to the ICU, intubated, and started on IV Decadron. Further imaging showed multiple enlarged lymph nodes in the axilla, mediastinum, and hilum. Her brain mass was biopsied showing acute inflammation with early acute necrosis and multifocal fibrinous vascular necrosis, which has been reported in ANCA vasculitis. She had undetectable TSH (0.35-5.0) and free T4 of 1.54 (4.87-11.72). She was also found to have proteinuria and AKI. At this point, PTU-induced vasculitis and drug-induced lupus were suspected and PTU was discontinued. She was found to have low complement levels (C3 40, C4 6.1), elevated p-ANCA (>1:1280), ANA (1:640), anti-histone IgG (2.3) dsDNA (1:160), SSB La antibodies (70), anti-Smith antibodies (319), anti-RNP antibodies (146). Renal biopsy is pending. After discontinuation of PTU and administration of IV steroids, her symptoms largely resolved and she was extubated and stable for discharge. Conclusion: In patients being treated for Graves’ disease with PTU, there are rare but life-threatening complications associated with this medication including lupus-like state or vasculitis with elevated ANCA antibodies. Common presenting symptoms of drug-induced vasculitis include fever, joint pains, myalgias, skin lesions, glomerulonephritis, cerebral angiitis, and pulmonary hemorrhage. The onset of vasculitis can occur at any time after starting medication, with one study showing an average onset of 36 months after initiation of therapy. Other case reports have demonstrated positive serologies for ANA and anti DS-DNA antibodies in those with PTU-induced lupus. Drug induced lupus can also occur in patients taking PTU, with kidney and CNS involvement being more uncommon. In those with p-ANCA associated vasculitis secondary to PTU, anti-GBM, antiphospholipid, and antinuclear antibodies can also be present. Presentation: 6/1/2024

Emerging Roles of IL-27 in Trophoblast Cells and Pregnancy Complications.

Pregnancy complications such as spontaneous abortion, preeclampsia, and preterm birth persist, despite current interventions aimed at their prevention and treatment largely proving unsuccessful. Interleukin-27 (IL-27), composed of p28 and EBI3 subunits, binds to IL-27R, which consists of gp130 and IL-27Rα (also known as WSX-1 or TCCR), and plays a pivotal role in tumor development and inflammation regulation. At the maternal-fetal interface, IL-27 expression has been detected in trophoblasts, endometrial stromal cells, and decidual cells. Abnormal levels of IL-27/IL-27R have been linked to adverse pregnancy outcomes, including spontaneous miscarriage, preeclampsia, and preterm birth. This review aims to explore the expression of IL-27 at the maternal-fetal interface and its signaling pathway, uncovering the complex role of IL-27 in pregnancy complications. A comprehensive literature review was conducted using PubMed/Medline, Scopus, and Embase databases, analyzing studies on IL-27 expression and its signaling pathways at the maternal-fetal interface. The review focused on identifying the presence of IL-27 in various cell types and linking abnormal IL-27/IL-27R expression to pregnancy complications such as spontaneous miscarriage, preeclampsia, and preterm birth. IL-27 plays a complex role at the maternal-fetal interface, with abnormal expression linked to several pregnancy complications. These findings highlight the need for further research to elucidate IL-27's mechanisms and develop targeted interventions. Future studies should aim to develop targeted interventions and improve therapeutic strategies for managing pregnancy complications.

Asymptomatic Group B Streptococcal infection, Antibiotic Sensitivity, Risk Factors and Pregnancy Outcome among Pregnant Women at the Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria

Background Streptococcus agalactiae or group B streptococcus (GBS), although a normal commensal, it is a leading cause of both maternal and neonatal sepsis. Objectives The study assessed the prevalence and sensitivity pattern of Group B Streptococcus, as well as the risk factors for infection and pregnancy outcome among pregnant women at the department of Obstetrics and Gynaecology of the Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria. Methods A prospective study among 152 pregnant women at the antenatal care clinic of Usmanu Danfodiyo University Teaching Hospital, Sokoto, selected by simple random sampling technique and relevant information was obtained using semi structured interviewer questionnaire. Swab samples were collected from the vagina and rectum for culture and further evaluation. The data was managed using SPSS software version 26 and the variables were analysed using descriptive and inferential statistics, and P- value < 0.05 was considered statistically significant. Result The prevalence of Group B Streptococcal infection among respondents was 4.6%. The mean age was 26.97± 5.6 with a range of 16 to 39 years. The organism was 100 % sensitive to Levofloxacin, Gentamycin and Clindamycin, but 57.1 %, 28.6 % and 14.3 % sensitive to Erythromycin, Augmentin and Penicillin respectively. The spousal educational status was statistically associated with GBS infection at a P- Value 0.04. There was 1(0.7%) each of spontaneous miscarriage and a preterm birth at 36 weeks’ gestation. Conclusion Group B Streptococcal infection is relatively common in our environment, with a contrary susceptibility pattern. It is association with spousal educational status.

NLRP3 Inflammasome in the Pathogenesis of Miscarriages

Despite significant advances in prenatal medicine, spontaneous miscarriage remains one of the most common and serious pregnancy complications, affecting an increasing number of women. Since many aspects of the pathogenesis of spontaneous miscarriage remain unexplained, the aim of this study has been to assess the involvement of the NLRP3 inflammasome as a potential causative factor. The concentrations of NLRP3, IL-1β, IL-18, and cytochrome C in the serum of patients after miscarriage were measured by means of the immunoenzymatic method. In the placental tissue, the expression of NLRP3, IL-1β, IL-18, and Caspase-1 as well as that of the classical apoptosis biomarkers Fas, FasL, Bcl-2, and Ca was evaluated by means of immunohistochemistry techniques. Additionally, in whole blood, the concentrations of elements crucial for pregnancy progression, such as Ca, K, Mg, and Na, were examined by means of the ICP-OES method. Significantly higher concentrations of NLRP3 and IL-18 were demonstrated in the serum of patients with miscarriage as compared to the control group. In the placental tissue samples, a higher expression of IL-1β, IL-18, and Caspase-1 proteins was noted in women who had experienced miscarriage as compared to the control group. At the same time, a significantly lower expression of FasL and Bcl-2 proteins as well as Ca deposits was observed in women after miscarriage as compared to those with a normal pregnancy outcome. Significantly lower concentrations of Ca and K were recorded in the blood of patients with spontaneous miscarriage as compared to pregnant women. The analysis of the results x indicated a greater involvement of the inflammasome in women with spontaneous miscarriage associated with oxidative–antioxidative imbalance than in the case of miscarriage related to NET formation. Our research has provided evidence for the involvement of the inflammasome in the process of spontaneous miscarriage and identifies a new direction for diagnostics that includes NLRP3 as a preventive element in prenatal care, particularly in light of the steadily declining number of pregnancies and the increasing number of reproductive failures.

Perspective in the Mechanisms for Repairing Sperm DNA Damage.

DNA damage in spermatozoa is a major cause of male infertility. It is also associated with adverse reproductive outcomes (including reduced fertilization rates, embryo quality and pregnancy rates, and higher rates of spontaneous miscarriage). The damage to sperm DNA occurs during the production and maturation of spermatozoa, as well as during their transit through the male reproductive tract. DNA damage repair typically occurs during spermatogenesis, oocytes after fertilization, and early embryonic development stages. The known mechanisms of sperm DNA repair mainly include nucleotide excision repair (NER), base excision repair (BER), mismatch repair (MMR), and double-strand break repair (DSBR). The most severe type of sperm DNA damage is double-strand break, and it will be repaired by DSBR, including homologous recombination (HR), classical non-homologous end joining (cNHEJ), alternative end joining (aEJ), and single-strand annealing (SSA). However, the precise mechanisms of DNA repair in spermatozoa remain incompletely understood. DNA repair-associated proteins are of great value in the repair of sperm DNA. Several repair-related proteins have been identified as playing critical roles in condensing chromatin, regulating transcription, repairing DNA damage, and regulating the cell cycle. It is noteworthy that XRCC4-like factor (XLF) and paralog of XRCC4 and XLF (PAXX) -mediated dimerization promote the processing of populated ends for cNHEJ repair, which suggests that XLF and PAXX have potential value in the mechanism of sperm DNA repair. This review summarizes the classic and potential repair mechanisms of sperm DNA damage, aiming to provide a perspective for further research on DNA damage repair mechanisms.

Cyclooxygenase 2 and prostaglandin E2 in the genesis of pregnancy loss in cytomegalovirus infection

Prostaglandins (PGs), regulated by cyclooxygenase (COX) 2, play a significant role in the development of placental disorders in pathological pregnancy. A review of current literature reveals a lack of evidence demonstrating the involvement of PGs in the pathogenesis of early spontaneous miscarriages associated with cytomegalovirus (CMV) infection. The aim of this study was to investigate the levels of COX-2 and PG E2 in peripheral blood and determine their significance in predicting pregnancy loss during exacerbation of CMV infection at 7-8 weeks gestation.Materials and methods. The study involved 70 patients experiencing an exacerbation of chronic CMV infection at 7-8 weeks of gestation, with 36 patients presenting with a threatened miscarriage (main group) and 34 patients without signs of threatened miscarriage (comparison group). CMV infection was diagnosed based on the presence of M and G class antibodies using enzyme-linked immunosorbent assay (ELISA), as well as CMV DNA detected by polymerase chain reaction. COX-2 levels in mononuclear cell lysates were determined using the "Assay Designs, COX-2" (USA) test systems, and PG E2 concentrations in blood serum were measured using "Cloud-Clone Corp." (USA) kits.Results. Women with exacerbated CMV infection associated with spontaneous miscarriage at 7-8 weeks of gestation exhibited elevated concentrations of COX-2 (23.0±2.20 ng/mL) and PG E2 (850.10±35.0 pg/mL, p<0.001) compared to pregnant women without threatened miscarriage (12.75±1.35 ng/mL and 42.0±2.80 pg/mL, respectively).Conclusion. The findings of this study underscore the significant role of elevated COX-2 and PG E2 concentrations in the pathogenesis of pregnancy loss during exacerbation of CMV infection at 7-8 weeks of gestation. The assessment of COX-2 and PG E2 levels should be considered as a predictive measure for the risk of pregnancy loss during exacerbation of CMV infection.

Environmental arsenic exposure and reproductive system toxicity in male and female and mitigatory strategies: a review.

Environmental Arsenic (As) exposure is one of the main health challenges in different area of the world. As is a significant factor responsible to the reproductive system toxicity in both male and female. In this study, the most important effects mechanisms and biomarkers related to environmental exposure to As and the reproductive system toxicity, and infertility risk are reviewed in male and female. The results showed that the most important As-induced reproductive system toxicity in the male were alteration in the quantity and quality of semen, testicular toxicity, oxidative stress, testosterone reduction, and sperm apoptosis. For female were oxidative stress, spontaneous miscarriage, reproductive cycle disruption, decrease in the estradiol, progesterone, and testosterone levels and impair fecundity. The main mechanisms of reproductive system toxicity caused by As exposure in male were, genotoxic effects, reduction of glutathione, disruption of sex hormones, sperm flagellum formation impairment, inhibition of spermatogenesis, disruption of cell signaling pathways, and metabolites disruption. For female were abnormal signaling in gene expression, hormonal homeostasis, As-accumulation in placental tissue and creation of reactive oxygen, disruption in the neurotransmitters balance, and sex hormones disruption. The suitable biomarkers for As-induced reproductive toxicity in male were changes in testosterone, one-carbon and lipid metabolism, noncoding RNAs, and steroid hormone homeostasis, and for female was human chorionic gonadotropin (hCG) changes. Finaly, taking selenium, zinc, silymarin, vitamins (C and E) and phytonutrients can be effective in reducing the As-induced reproductive system toxicity and infertility risk.

Fluorescent, pH, and UCST Responsive Polymer Nanomaterials for Treatment of Recurrent Miscarriage.

Recurrent miscarriage (RM), defined as three or more consecutive spontaneous miscarriages, affects many women of childbearing age. The pathological basis of RM is an imbalance in apoptosis, with the MDM2-p53 pathway playing a crucial role. In this study, we synthesized poly(6-acetoxyl-ε-caprolactone)-graft-(4-amino-benzimidazole) (PCCL-4-ABI) by modifying poly(6-acetoxyl-ε-caprolactone) (PCCL) with 4-amino-benzimidazole (4-ABI). The introduction of carboxyl and 4-ABI groups endowed the PCL backbone with fluorescence, pH responsiveness, and UCST responsiveness. The temperature-dependent release behavior of compound 1-loaded PCCL-4-ABI nanofluorescent materials was attributed to UCST transition. We successfully developed a novel nanofluorescent polymer drug delivery platform, PCCL-4-ABI@1, and evaluated its regulatory effects on p53 and MDM2 in trophoblast cells (HTR-8/SVneo). The results showed that the system loaded with low molecular weight heparin increased MDM2 and decreased p53 expression in a dose-dependent manner, thereby inhibiting trophoblast cell apoptosis. This study developed a biodegradable poly(ε-caprolactone) with UCST behavior, significant for the advancement of thermoresponsive fluorescent nanoparticle systems.

A Hypoxia-Decidual Macrophage Regulatory Axis in Normal Pregnancy and Spontaneous Miscarriage.

The significance of hypoxia at the maternal-fetal interface is proven to be self-explanatory in the context of pregnancy. During the first trimester, low oxygen conditions play a crucial role in processes such as angiogenesis, trophoblast invasion and differentiation, and immune regulation. Recently, there has been increasing research on decidual macrophages, which contribute to the maintenance of immune tolerance, placental and fetal vascular development, and spiral artery remodeling, to investigate the effects of hypoxia on their biological behaviors. On these grounds, this review describes the dynamic changes in oxygen levels at the maternal-fetal interface throughout gestation, summarizing current knowledge on how the hypoxic environment sustains a successful pregnancy by regulating retention, differentiation and efferocytosis of decidual macrophages. Additionally, we explore the relationship between spontaneous miscarriages and an abnormal hypoxia-macrophage axis, shedding light on the underlying mechanisms. However, further studies are essential to elucidate these pathways in greater detail and to develop targeted interventions that could improve pregnancy outcomes.

Efficacy of intrauterine autologous blood cell derivatives in enhancing endometrial thickness and IVF outcomes for women with recurrent implantation failure: a retrospective cohort study

PurposeThe purpose of this study was to determine the effects of intrauterine infusion of autologous blood cell derivative (ABCD) on endometrial thickness and pregnancy outcomes in a group of patients who underwent IVF with recurrent implantation failure (RIF) and who had either a normal endometrium or thin endometrium.MethodsThis retrospective study included 63 patients who experienced RIF at the Department of Reproductive Medicine and Surgery, KMC, Manipal, between January 2021 and March 2024 and who received three doses of intrauterine ABCD infusion to prepare the endometrium for frozen embryo transfer (FET).ResultsWe enrolled 63 RIF patients, 30 with a normal endometrium (NEM) and 33 with a thin endometrium (TEM). The endometrial thickness (EMT) significantly increased across all the groups. After 3 cycles of intrauterine ABCD infusion, the mean increases in EMT in the NEM and TEM groups were 0.77 mm and 1.36 mm, respectively, which were statistically significant. Among the 62 completed FET cycles, 40.3% were positive for beta-hCG. The clinical pregnancy rate was 33.8% (40% in the NEM group, 28.1% in the TEM group), and the live birth rate was 24.2% (30% in the NEM group, 18.8% in the TEM group). A total of 9.7% of pregnancies had spontaneous miscarriages. Moreover, the EMT did not differ between the pregnant and nonpregnant groups.ConclusionIntrauterine ABCD infusion improves the pregnancy outcomes of patients with RIF, regardless of the EMT. The results of this study revealed that endometrial receptivity improved significantly along with the EMT.

Exploring the link between chromosomal polymorphisms and reproductive abnormalities

ObjectiveThis work aimed to investigate the potential correlation between chromosomal polymorphisms and various reproductive abnormalities.MethodsWe examined 21,916 patients affected by infertility who sought care at the Department of Reproductive Medicine, Affiliated Hospital of Shandong Second Medical University between January 2018 and December 2022. A total of 2227 individuals identified as chromosomal polymorphism carriers constituted the polymorphism group, and 2245 individuals with normal chromosome karyotypes were randomly selected to form a control group. Clinical manifestations, histories of spontaneous miscarriage, abnormal reproductive developments, fetal abnormalities, and male sperm quality anomalies were statistically compared between these two groups.ResultsOf the 21,916 patients analyzed, 2227 displayed chromosomal polymorphism, representing a 10.16% detection rate. Amongst the male patients, 1622 out of 10,827 exhibited polymorphisms (14.98%), whereas 605 out of 11,089 females showed polymorphisms (5.46%). Female carriers in the polymorphism group, showed statistically significant increased rates of spontaneous abortion (29.75% vs. 18.54%), fetal anomalies (1.32% vs. 0.81%), and uterine abnormalities compared with the control group (1.32% vs. 0.81%). Male carriers in the polymorphism group had higher rates of spontaneous abortion in partners (22.87% vs. 10.37%), fetal anomalies (1.97% vs. 0.25%), compromised sperm quality (41.74% vs. 7.18%), testicular underdevelopment (2.28% vs. 0.92%), and hypogonadotropic hypogonadism (0.62% vs. 0.37%) compared with the control group.ConclusionChromosomal polymorphisms may have a certain negative effect on reproductive irregularities, including spontaneous abortions, fetal anomalies, and reduced sperm quality in males. Their clinical effects deserve further investigation.

Causal Association of Rheumatoid Arthritis With Adverse Pregnancy Outcomes: Genetic Evidence From Mendelian Randomization.

Although the association of rheumatoid arthritis (RA) to multiple adverse pregnancy outcomes has been well-studied, the association between serum antibody levels in patients with RA and multiple adverse pregnancy outcomes has not been conclusively demonstrated. Here, we comprehensively assessed the causal impact of RA, serologic antibody-positive RA (pRA), and serologic antibody-negative RA (nRA) on the risk of 14 adverse pregnancy outcomes. The causal impact of RA, pRA, and nRA on 14 adverse pregnancy outcomes was comprehensively assessed using two-sample Mendelian randomization (MR). Evidence maps based on the results of these two-sample MR analyses were developed. Data from the UK Biobank and FinnGen databases were utilized for this analysis. The inverse variance weighted (IVW) test was employed as the primary method to estimate causality. "TwoSampleMR" and "MR-PRESSO" packages were used for data analysis in this study. Using two-sample MR analysis, we found a significant positive causal association between RA and increased risk of cesarean section (p=0.003), gestational hypertension (p < 0.001), number of spontaneous miscarriages (p=0.041), preeclampsia (p=0.008), premature rupture of membranes (p=0.030), and preterm (p=0.010). pRA had a significant positive causal association with an increased risk of cesarean section (p=0.012), gestational hypertension (p < 0.001), preeclampsia (p=0.002), and preterm (p=0.007). A significant positive causal association was also established between nRA and gestational hypertension (p=0.010), the number of spontaneous miscarriages (p=0.024), and placental abruption (p=0.027). In addition, we found a causal association between nRA and birth weight (p=0.007), but not between RA and pRA and birth weight. The results of this study have important implications for the individualized treatment of RA patients, especially those with positive serum antibody levels.

Witzenberg Women's experience of health care after a miscarriage: A descriptive qualitative study.

Although some evidence is available from low- and middle-income countries, no South African data are available on how women experience healthcare during treatment for an incomplete miscarriage. This study sets out to explore and describe the experiences of healthcare among women who suffered an incomplete spontaneous miscarriage in the Witzenberg subdistrict, a rural area in the Western Cape province of South Africa. Witzenberg subdistrict, Western Cape province, South Africa. This study used a descriptive exploratory qualitative study design. In-person interviews were held with women who experienced a miscarriage. Interviews followed a semi-structured format by a single interviewer to explore the various aspects involving experiences of healthcare. Eight interviews were conducted and analysed. The five themes that arose from transcribed data were: (1) a need for safety, (2) pain management, (3) moderating behaviours and attitudes, (4) disorienting healthcare systems and (5) abandonment. Several factors contributed to the loss of physical and emotional safety in the emergency centre environment. Timeous emotional and pharmacological pain management were found to be a gap while patients awaited care. Clear communication and staff attitude were found to be integral to the patient's experience and could avoid the perception of abandonment. There is a universal need for basic respectful, supportive and safe care in patients who attend an emergency centre for early pregnancy complications in rural South African. Specific focus should be given to clear communication and appropriate emotional support during and after the miscarriage.Contribution:This study can be used as a guide to improve services by ensuring respectful, transparent, informed, and appropriate continuity of care.

The impact of COVID-19 infections on pregnancy outcomes in women

BackgroundGiven that viral infections can increase the risk of adverse pregnancy outcomes, such as spontaneous miscarriage, preterm premature rupture of membranes, and preterm birth, the effects of COVID-19, a novel emerging coronavirus disease rapidly spreading globally, on pregnancy outcomes have garnered significant attention.MethodsWe conducted a review of studies related to pregnant women infected with SARS-CoV-2 over the past five years (December 2019 to April 2023), utilizing search engines such as PubMed, Web of Science, and the China National Knowledge Infrastructure (CNKI). This study was registered with PROSPERO with ID: CRD42024540849.ResultsA total of 218 articles were screened, with 15 studies meeting the inclusion criteria for this research, including 12 cohort studies, one cross-sectional study, one case-control study, and one case series. Six studies found that the preterm birth rate was higher in the infected group compared to the control group; five studies showed that the cesarean section rate was higher in the infected group; three studies found that the APGAR scores of newborns were higher in the control group than in the infected group; three studies indicated that the mortality rate of newborns in the infected group was higher than that in the control group.ConclusionsOur retrospective review suggests that compared to pregnant women not infected with SARS-CoV-2, those diagnosed with COVID-19 are more likely to experience adverse outcomes such as preterm birth, cesarean delivery, and low birth weight in newborns.

CHARACTERISTICS OF RISK FACTORS FOR THE DEVELOPMENT OF PRIMARY PLACENTAL DYSFUNCTION IN WOMEN WITH A THREAT OF ABORTION IN THE FIRST TRIMESTER OF PREGNANCY

The aim of the study – to optimize the prediction of primary placental dysfunctiondevelopment by determining the risk factors for its development in women with a threatof miscarriage in the early stages of pregnancy.Materials and methods. A prospective analysis of the somatic, reproductive and obstetricanamnesis of 40 pregnant women with threatened abortion in the 1st trimester ofpregnancy and clinical manifestations of placental dysfunction (PD) was carried out –the main group, 60 pregnant women with threatened abortion without PD (comparisongroup). The control group consisted of 50 women with the physiological course of the firsttrimester of pregnancy. Results. Among those with symptoms of threat of termination of pregnancy in the earlystages of pregnancy and PD, the number of women of borderline reproductive age (≤18years and ≥40 years), with obesity (BMI &gt; 30) and a combination of several co-morbidextragenital pathologies was significantly higher than in the comparison group and inthe control group. In the anamnesis of pregnant women of the main group, gynecologicaldiseases, early pregnancy losses (spontaneous miscarriages and non-developingpregnancies) were significantly more often detected. In the first trimester of pregnancyvaginal bleeding, chorionic detachment, retrochorionic hematoma, and low chorionicposition were diagnosed significantly more often in women of the main group. In 7.5 % ofcases, in the first trimester of pregnancy, pregnant women with a threat of abortion andPD had an acute respiratory viral infection.The relationship between the development of primary PD and the frequency of gestationalcomplications associated with the placenta (PE (20.0 %), Abruptio placentae (17.5 %),fetal growth retardation syndrome (10.0 %) and fetal distress (27.5 %)) was established.Every third pregnancy ended in premature birth (32.5 %). The percentage of deliveries byCS in the main group was 62.5 %. Complications of pregnancy and childbirth, associatedwith impaired placental function, led to a high frequency of births of babies in a state ofmoderate and severe asphyxia (15.0 % and 5.0 %, respectively) and stillbirths.Conclusions. The conducted studies confirmed that the development of placentaldysfunction from the early stages of pregnancy in women with a threat of abortion isthe cause of the complicated course of pregnancy and childbirth, which lead to adverseperinatal consequences. Risk factors for the development of placental dysfunctionin pregnant women with threatened abortion are the borderline reproductive age ofthe mother, obesity, a combination of several co-morbid extragenital pathologies,gynecological diseases and early reproductive losses in the anamnesis. Also, the riskfactors for impaired placental formation are detachment of the chorion, retrochorialhematoma, and acute respiratory viral infections in the early stages of pregnancy.

RISK FACTORS OF LOW PLACENTATION

The purpose of the study – to assess the risk factors for the occurrence of low placentationin the early stages of gestation.Materials and methods. A clinical and statistical analysis of 150 individual charts ofpregnant women and women in labor in women with a low lying placenta (main group)and 80 pregnant women with a normal localization of the placenta in the fundus andbody of the uterus (control group), who were under dispensary supervision in a women’sconsultation, was carried ou.tThe results. After conducting the analysis, it was established that the main groupwas dominated by women over 30 years old (40.7 % of cases), compared to 25.0 %of pregnant women in the control group (p&lt;0.05). The age of onset of menarche after14 years is marked significantly more often in pregnant women with low placentation –in 22.7 %, compared to normal localization of the placenta – in 8.8 % of cases. Thedevelopment of the menstrual cycle by one year in the main group was 2.5 times lessfrequent than in the control group. 58.7 % of pregnant women with low placentationhad 2 or more artificial abortions, 46 % had a history of spontaneous miscarriages, inpregnant women with normal placentation, these indicators were 32.5 % and 18.8 % ofpregnant women, respectively (p&lt;0.05). In 20.7 % of cases of women in the main group,childbirth was completed by cesarean section, and in the control group – in 7.5 % ofcases. In pregnant women with low placentation, 26.0 % had inflammatory diseases ofthe uterine appendages, 50.7 % had cervical erosion, 10.7 % had uterine fibroids, 16.7 %had endometriosis, compared to the control group in 17 .5 %, 36.3 %, 3.8 % and in 6.3 %of cases, respectively (p&lt;0.05). Conservative myomectomy was performed in 30 % ofcases of the main group and 12.5 % of women in the control group. Conclusions. Risk factors for low placentation are a woman’s age over 30 years, latemenarche and late onset of menstrual function, history of gynecological diseases, highbirth parity, history of spontaneous miscarriages and artificial abortions, uterine scar,and manual revision of the uterine cavity walls. Identifying the risk factors for lowplacentation will reduce the level of perinatal and obstetric complications.

RISK FACTORS FOR THE DEVELOPMENT OF PLACENTAL DYSFUNCTION ON THE BACKGROUND OF PREGNANT WOMEN GENITAL INFECTIONS

The progress of perinatology revealed new problems related to the gestational process and antenatal protection of the fetus. Among indicators of perinatal morbidity in modern conditions, one of the leading places occupied by placental dysfunction, the frequency of which, according to the data of domestic and foreign scientists ranges from 36% to 60%. It is known that among the many factors that affect the complicated course of pregnancy and perinatal morbidity, infectious factors in modern conditions occupy one of the leading places. Despite certain achievements in elucidating the etiological factors and pathogenesis of the development of placental dysfunction (PD), the issues of diagnosis and treatment of this pathology in pregnant women need further improvement. Thus, the study of links in the pathogenesis of manifestations of placental dysfunction, which develops during pregnancy in the early stages of gestation against the background of genital infections, is relevant and promising.The purpose. To assess the risk factors for the development of placental dysfunction in pregnant women with genital infections.Material and methods. The retrospective comparative study included 55 women who gave birth after involuntary childbirth according to the regional perinatal center of Chernivtsi, who had signs of placental dysfunction and genital infections during pregnancy during the period 2021-2022.Research results. One of the most important factors affecting the fetoplacental system, which leads to the development of chronic PD (CPD), are infections of the TORCH group. Infections during pregnancy, depending on the gestational period, lead to miscarriage, abortion, stillbirth, malformations of the child, cerebral defects, as well as to acute and chronic neonatal diseases. We conducted a retrospective analysis of risk factors, the frequency and structure of obstetric complications based on the data of 55 birth stories of the regional perinatal center in Chernivtsi for 2021-2022. Manifestations of placental dysfunction against the background of genital infections were studied at different gestational periods. Placental dysfunction occurs at different gestational periods in women of different ages. However, in young people (up to 18 years old) it occurs less often at all stages of gestation, compared to other age categories. A significant number of pregnant women with manifestations of placental dysfunction suffered from infectious diseases in childhood (measles, chicken pox, acute respiratory and viral infections, angina, various disorders of menstrual function (hyperpolymenorrhea, hypomenstrual syndrome, algodysmenorrhea) were quite often observed in pregnant women with manifestations of placental insufficiency. More often, placental dysfunction develops during first births than during repeated births. Cases of stillbirth, spontaneous miscarriages, artificial abortions and ectopic pregnancies often occur in the anamnesis. A number of authors [41] indicate that pregnant women with manifestations of placental insufficiency often experience various complications of the current pregnancy. Modern scientific studies show that almost 80% of pregnant women with genital infections show significant changes in the immune, endocrine and coagulation systems, which lead to a violation of the formation of the fetoplacental complex and a violation of adaptation mechanisms in the mother-placenta-fetus system.Conclusion. Clinical and statistical analysis shows the negative impact of manifestations of genital infections in different gestational periods on the course of pregnancy and the state of the fetus and newborn. The conducted studies on this issue give reason to talk about the need to review the system of obstetric tactics for these pregnant women, and further improvement of medical measures for antenatal protection of the fetus with this complication of pregnancy.

AB064. Two case reports & review of literature: perioperative surgical management of symptomatic large non-functioning pituitary masses in early pregnancy.

Pituitary masses during pregnancy pose many challenges, requiring inputs from multidisciplinary teams. Where surgery is required, such as in cases of impending pituitary apoplexy, timing must be carefully selected. Several case reports have suggested good outcome with surgery in later trimesters or postpartum. However, insufficient data exists on surgical strategies for such patients with severe visual symptoms in early pregnancy. We report two patients with pituitary masses requiring surgical excision. Review of patients' notes and imaging, with literature review. A 35-year-old gravida 2 para 1 female at 9 weeks gestational age (GA) presented with chronic bitemporal hemianopia, with acute left eye blurring of vision, identified during a pre-employment screening test. Imaging revealed a 38 mm × 29 mm × 33 mm sellar mass with compression onto the optic chiasm. She had no significant hormonal imbalances other than hyperprolactinemia and newly diagnosed Hashimoto's thyroiditis. She underwent transsphenoidal resection, with histology showing pituitary adenoma with blood clots. Similarly, our second patient was a 37-year-old gravida 4 para 2 female at 12 weeks GA with worsening bitemporal hemianopia with a 25 mm × 21 mm × 18 mm sellar mass displacing and compressing the optic chiasm. After resection she had marked objective improvement in her vision, but developed diabetes insipidus, and final histology revealed pituicytoma. Preoperative considerations for timing of surgery include pituitary apoplexy or acutely worsening visual field deficit. The pituitary physiologically increases in size during pregnancy, which can compress the optic chiasm and worsen visual deficit. In the case of apoplexy, delayed identification can have devastating consequences. However, major surgery in the first trimester may increase spontaneous miscarriage. The effects of imaging investigations from radiation, or gadolinium contrast administration, are also uncertain. While surgical positioning remains unaffected, other intraoperative considerations include strictly avoiding hypotension and using pregnancy-safe agents. Postoperative considerations include correcting hormonal deficiencies of hypopituitarism, including acute central hypocortisolism, diabetes insipidus and interruption of gonadotrophin production which could negatively affect pregnancy. Fetal heart rate must also be assessed. Determining timing of surgery to ensure well-being of both mother and fetus involves a difficult balance of risks. In our two cases, a thorough discussion with multidisciplinary input was required to achieve good outcomes.
