The effect of COVID-19 lockdown on admission rates in Maternity Hospital.

The COVID-19 pandemic had adverse health outcomes on individuals and communities. In this cross-sectional study we evaluated the admission rates in a tertiary-level hospital during the first wave of the pandemic (March 22, 2020 to August 31, 2020). We compared the indications for admission during the first wave of the pandemic to a control period prior to the lockdown (November 9, 2019 to March 22, 2020). Most hospital admissions during the curfew period were obstetric emergencies (46.88%), which were significantly higher than the control group (38.19%) p ≤ 0.0001. Among the obstetric emergencies, cases in active labor (65.63%) were dominant. Significant rises in car deliveries (2.46%, p ≤ 0.0001) and admissions during the second stage of labor (6.43%, p ≤ 0.001) were noted. There was also an increased rate of admissions for early pregnancy complications, induction of labor, elective obstetric cases, and medical obstetric cases. This study demonstrates that lockdown precautions implemented had a significant impact on the rate of admissions to Maternity Hospital. The data obtained may be a used to aid in designing robust policies for future pandemics to avoid adverse health outcomes.

Gestational diabetes complicated with preterm birth: a retrospective cohort study

ObjectiveTo delineate the clinical characteristics of preterm birth (PTB) in the context of gestational diabetes mellitus (GDM).MethodsA retrospective cohort study was conducted, including 14,314 pregnant women with GDM who delivered at Fujian Provincial Maternity and Children’s Hospital from January 1, 2018, to December 31, 2021. PTB was stratified into late PTB (34–36 weeks of gestation) and early PTB (< 34 weeks) and pregnancy complications were analyzed.ResultsCompared to the term birth (TB) cohort, a higher prevalence of premature rupture of membranes, hypertensive diseases of pregnancy (HDP), intrahepatic cholestasis of pregnancy (ICP), anemia and cervical insufficiency was observed in the PTB cohort. Notably, early PTB increased the incidence of HDP, ICP, anemia and cervical insufficiency compared to late PTB. In the early stages of pregnancy, early PTB was characterized by elevated triglyceride (TG) levels and decreased high-density lipoprotein cholesterol (HDL-C) levels compared to late PTB. In the late pregnancy stages, early PTB was associated with increased white blood cell (WBC) and neutrophil counts. No disparities were observed in 75 g oral glucose tolerance test (OGTT) between early and late PTB.ConclusionEnhanced surveillance and management of GDM, particularly in the presence of HDP, ICP and anemia, are imperative to mitigate the risk of PTB. The lipid profile may serve as a predictive tool for early PTB in the early stages of pregnancy, warranting further studies.

A Study to Assess the Knowledge regarding Complications of Early Marriage and Teenage Pregnancy among Parents of Teenage Girls at selected Community

BACKGROUND: Early marriage refers to any marriage happens under the age of 18 years, where the girl is not ready for the marriage and childbirth. Teenage pregnancy is defined as pregnancy in a female adolescent as the period between the age of 13 to 19 years. Over 700 million women were married before being 18 years old in the World. This research study was conducted to assess the knowledge regarding complications of early marriage and teenage pregnancy among parents of teenage girls at selected community, Srikakulam, Andhra pradesh. STATEMENT OF THE PROBLEM: A descriptive study to assess the knowledge regarding complications early marriage and teenage pregnancy among parents of teenage girls at selected community, Srikakulam, Andhra pradesh. METHOD: A descriptive research design was used and a total of 30 parents of teenage girls in selected community at Srikakulam were selected by using non-probability convenience sampling techniques. Data was collected by using structured interview questionnaires by using descriptive and inferential statistical techniques. RESULTS: The study revealed that among 30 parents, 0(0%) had inadequate knowledge, 23(76.6%) had moderate knowledge and 7(23.3%) had adequate knowledge regarding complications of early marriage and teenage pregnancy. CONCLUSION: Findings of the current study revealed that the knowledge regarding the complications of early marriage and teenage pregnancy among parents of teenage girls was not satisfactory and had to improve significantly.

Risk and protective factors of miscarriage: Evidence from a nationally representative sample of women in India.

Miscarriage is the most distressing complication in early pregnancy, with one in every five pregnant women ending in a miscarriage, and its causes are multifactorial. This study aimed to find the risk and protective factors of miscarriage among women aged 15-49 years in India by using the National Family Health Survey (NFHS-5) data. The data were taken from NFHS-5; 53,560 women aged 15-49 years who had reported either a miscarriage (n = 5104) or livebirth (n = 48,456) during the last 12 months preceding the survey were included in the study. Various sociodemographic, lifestyle, comorbid, and fertility-related factors were considered in the Poisson regression analysis, and adjusted prevalence ratios were obtained. Significant sociodemographic risk factors were age less than 20 years or more than 34 years, urban residence, primary and higher education levels, wealth index middle and above, and occupation as employed. Muslim religion, Scheduled Tribe, and Other Backward Class castes were statistically significant protective factors. Obesity, severe anemia, hypertension, and thyroid disorder were the significant comorbid risk factors, whereas tobacco chewing was the only significant lifestyle risk factor. A higher number of ever-born children was the fertility-related risk factor, whereas the use of intrauterine devices was a significant protective factor for miscarriage. To reduce the incidence of miscarriage in developing countries like India, the respective governments and healthcare providers should develop intervention programs targeting women in well-educated and high-income families.

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.

Preliminary findings on the experiences of care for women who suffered early pregnancy losses during the COVID-19 pandemic: a qualitative study

BackgroundWomen 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.MethodsIn-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.ResultsAll 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.ConclusionsThese 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.

Medical management of first trimester missed miscarriages - A cross-sectional study.

Miscarriage, a common complication of early pregnancy before 12 completed weeks of gestation, is typically managed medically. We aimed to estimate the success and complication rate of medical management in women with first-trimester missed miscarriages. Our objective was to calculate the rate of complete uterine evacuation within three weeks of treatment, rate of infection, significant blood loss, re-admission, or surgical evacuation. It was a retrospective cross-sectional study that included women diagnosed with miscarriage at less than 13 weeks' gestation in Latifa Hospital's Gynecology Department from January 2019 to December 2019 in Dubai. These patients were given vaginal misoprostol, 400-800 mcg every 6-8 hours until expulsion of pregnancy. There were 294 women included in the study. The success rate was 60.5% (178/294). Twenty women developed significant blood loss (6.8%), four women developed infection (1.4%), 76 required readmission (25.9%), 12 women received blood transfusion (4.1%), and 74 women required a surgical evacuation (25.2%). Nulliparity, unscarred uterus, and the presence of abdominal pain with vaginal bleeding before treatment were significantly associated with the successful medical treatment (p<0.05). The success rate of the medical regimen studied lies on the lower end of what is quoted in the literature. The difference in the success rate could be attributed to the different definitions of success in other studies. Nulliparity, unscarred uterus and presence of abdominal pain with vaginal bleeding were associated with higher success.

Systemic methotrexate (MTX) in early pregnancy: a retrospective study of a tertiary maternity hospital

BackgroundMethotrexate (MTX) is used in clinical practice as a medical treatment option in patients with early pregnancy complications like ectopic pregnancy.AimsTo review systemic MTX therapy use in the first trimester of pregnancy in our hospital and to examine subsequent clinical outcomes.MethodsRetrospective review of all women treated with systemic MTX in early pregnancy identified from electronic prescription records from 1 January 2018 to 31 December 2020 at Cork University Maternity Hospital, Ireland. Relevant data was transcribed from electronic health records.ResultsIndications for treatment were tubal ectopic pregnancy (70%, n = 51), persistent pregnancy of unknown location (22%, n = 16) and caesarean scar pregnancy (7%, n = 5). Treatment was successful in 88% (n = 44) of tubal ectopic pregnancies with 73% (n = 37) and 14% (n = 7) of women receiving a single dose and repeated doses, respectively. Only 8% (n = 4) of tubal ectopic pregnancies required emergency surgery for subsequent tubal rupture. In 93% (n = 15) of cases of persistent pregnancy of unknown location, treatment was successful with one patient requiring uterine evacuation. Women with caesarean scar pregnancy were treated with combined MTX and uterine evacuation without complication.ConclusionsThe efficacy of medical treatment with systemic MTX for confirmed tubal ectopic pregnancy in our hospital is in line with national and international standards. Careful consideration should be given to treating caesarean scar pregnancy and persistent pregnancy of unknown location with systemic MTX. Systemic MTX use guided by clinicians specialised in early pregnancy complications and safe medication practices may improve treatment success and reduce adverse events.

O-206 Natural, modified natural or artificial endometrial preparation strategies for frozen embryo transfer in ovulatory women (MONART): a randomized controlled trial

Abstract Study question Are live birth rates after natural (NC), modified natural (mNC) endometrial preparation superior to artificial cycle (AC) strategies for ovulatory women undergoing frozen embryo transfer? Summary answer Live birth rates were comparable between NC, mNC, and AC. However, NC and mNC resulted in a significantly higher cycle cancellation rate. What is known already The number of frozen embryo transfer (FET) cycles has increased dramatically. In ovulatory women undergoing FET, three common strategies can be used for endometrial preparation: NC, mNC (NC + human chorionic gonadotropin trigger), and AC protocols. Previous studies comparing the effectiveness of these strategies had several drawbacks, including small sample size, lack of consistency between studies in the assessment and reporting of outcomes, and the retrospective origin, which introduced potential biases. Therefore, there is a lack of consensus on the optimal endometrial preparation protocol for FET. Study design, size, duration This single-center, open-label, randomized controlled trial was conducted at IVFMD, My Duc Hospital in Ho Chi Minh City, Vietnam. From March 2021 to March 2022, a total number of 1,428 participants were randomized (476 per group). The primary outcome of the study was live birth after one FET. Secondary outcomes were fertility outcomes, early pregnancy complications, obstetrical outcomes, perinatal and neonatal complications, and endometrial preparation cycle cancellation rates. Participants/materials, setting, methods Eligible participants were ovulatory women aged 18–45 with FET treatment, underwent no more than three IVF/intracytoplasmic sperm injection-FET cycles, had no more than two day-3 or one blastocyst transferred. Women with menopause/anovulation, contraindications for hormonal administration, uterine abnormalities who underwent in-vitro maturation, pre-implantation genetic testing, oocyte donation cycles were excluded. The FET strategies included FET after the first endometrial preparation cycles with AC, mNC, or NC, as per randomization, and the second with AC. Main results and the role of chance A total of 4,779 participants were screened, of whom 1,428 eligible individuals (476 per group) were randomized after written informed consent. The live birth rate after one FET was 36.6% (174/476) in the natural cycle strategy group, 33.4% (159/476) in the modified natural cycle strategy group, and 34.0% (162/476) in the artificial cycle strategy group (relative risk [95% confidence interval] for natural versus artificial cycle strategy: 1.07 [0.87–1.33] and for modified natural versus artificial cycle strategy: 0.98 [0.79–1.22]). Maternal and neonatal outcomes were comparable between groups, in particular,hypertensive disorders in pregnancy. For both natural and modified cycle groups, 20.08% (99/476) of the first FET cycles were canceled before subsequent successful ET versus none in the artificial cycle group. Limitations, reasons for caution Due to the nature of the intervention, blinding was not possible. The study was conducted in ovulatory women in a single center in Vietnam, which may limit the generalisability of the findings. Wider implications of the findings Live birth rates and obstetric/neonatal outcomes after the natural cycle, modified natural cycle, or artificial cycle strategies for ovulatory women undergoing FET are comparable, with higher cancellation rates in both the natural cycle and the modified natural cycle groups. Trial registration number NCT04804020

P-286 Comparative study of frozen-thawed embryo transfer with modified natural cycle versus HRT cycle in previously cancelled true natural cycle patients

Abstract Study question Is there any difference in outcome of frozen embryo transfer(FET) between hormone replacement therapy(HRT) and modified natural cycle(MNC) in previously cancelled true natural cycle patients Summary answer In patients with previous history of cancelled true natural cycle, MNC results in higher clinical pregnancy rates after FET, when compared to HRT cycle What is known already Preparation of endometrium lays down the foundation for conception and subsequent successful pregnancy.There has been a plethora of endometrial preparation protocols described in the literature. The established protocols are true natural cycle,MNC with or without luteal phase support(LPS) and HRT cycle with or without gonadotrophin releasing hormone agonist(GnRha) suppression. Nevertheless,there is no consensus on protocol which may provide the best outcome in patients who have had cancelled true natural cycle.In such situations,HRT cycle may be considered as an easy option as the cancellation rate is low.However,HRT treatment is known for higher early pregnancy and obstetric complications,compared to MNC Study design, size, duration Prospective observational study,where 155 patients undergoing FET who had minimum one true natural cycle cancellation were recruited.They were divided into group A undergoing HRT cycle(n = 77) and group B for MNC cycle(n = 78).The study was conducted in a fertility unit over six months from June-November 2023.Primary outcome measures were serum betaHCG estimation and ultrasonographic documentation of intrauterine pregnancy.Results were analysed using statistical software SPSS version25 and p value of less than 0.05 was considered statistically significant Participants/materials, setting, methods HRT patients received injectable GnRha 3.75 mg on day21 of previous cycle.Oral estradiol valerate 6mg daily started on day2 of menses. When ET was minimum 7mm, luteal phase support(LPS) was started with daily oral and vaginal progesterone(30mg and 600mcg respectively),followed by FET. MNC patients received Letrozole 5mg daily from day 2-6 of menstruation.rhCG 250mcg was given subcutaneously,when ET was at least 7mm,dominant follicle 16-18mm and progesterone(P4) less than 1ng/ml.LPS(vaginal progesterone600mcg) was started 36hours after rHCG,followed by FET Main results and the role of chance Mean ET in MNC group was 8.92mm ± SD1.38, which was higher than HRT group (8.31 mm ± SD0.89). This difference was statistically significant with a p value of 0.014.Serum beta HCG estimation was done 2weeks after FET. In HRT group beta HCG was positive in 41 out of 77(53.25%) and in MNC group positivity was higher being 48 out of 78(61.54%). However, this difference was not statistically significant. Transvaginal ultrasonography(TVS) was done to confirm intrauterine pregnancy 2weeks after beta HCG assay. Clinical pregnancy rate(CPR) was higher in MNC group with 32 out of 78(41.03%),compared to 18 out of 77(23.38%) in HRT group. This difference is statistically significant with p value of 0.019 Limitations, reasons for caution Relatively small population in this study may be the reason for caution to interpret the statistical data. Study with higher numbers may bring about more robust conclusions Wider implications of the findings Patients with failed true natural cycles may be considered for modified natural cycle(MNC) stimulation for FET, without attempt of another true natural cycle stimulation Trial registration number NOT APPLICABLE

Diagnostic efficacy of virtual organ computer-assisted analysis in measuring the volume ratio of subchorionic hematoma with serum progesterone

BACKGROUND Subchorionic hematoma (SCH) is a common complication in early pregnancy characterized by the accumulation of blood between the uterine wall and the chorionic membrane. SCH can lead to adverse pregnancy outcomes such as miscarriage, preterm birth, and other complications. Early detection and accurate assessment of SCH are crucial for appropriate management and improved pregnancy outcomes. AIM To evaluate the diagnostic efficacy of virtual organ computer-assisted analysis (VOCAL) in measuring the volume ratio of SCH to gestational sac (GS) combined with serum progesterone on early pregnancy outcomes in patients with SCH. METHODS A total of 153 patients with SCH in their first-trimester pregnancies between 6 and 11 wk were enrolled. All patients were followed up until a gestational age of 20 wk. The parameters of transvaginal two-dimensional ultrasound, including the circumference of SCH (Cs), surface area of SCH (Ss), circumference of GS (Cg), and surface area of GS (Sg), and the parameters of VOCAL with transvaginal three-dimensional ultrasound, including the three-dimensional volume of SCH (3DVs) and GS (3DVg), were recorded. The size of the SCH and its ratio to the GS size (Cs/Cg, Ss/Sg, 3DVs/3DVg) were recorded and compared. RESULTS Compared with those in the normal pregnancy group, the adverse pregnancy group had higher Cs/Cg, Ss/Sg, and 3DVs/3DVg ratios (P &lt; 0.05). When 3DVs/3DVg was 0.220, the highest predictive performance predicted adverse pregnancy outcomes, resulting in an AUC of 0.767, and the sensitivity, specificity were 70.2%, 75% respectively. VOCAL measuring 3DVs/3DVg combined with serum progesterone gave a diagnostic AUC of 0.824 for early pregnancy outcome in SCH patients, with a high sensitivity of 82.1% and a specificity of 72.1%, which showed a significant difference between AUC. CONCLUSION VOCAL-measured 3DVs/3DVg effectively quantifies the severity of SCH, while combined serum progesterone better predicts adverse pregnancy outcomes.

Midwives' and registered nurses' role and scope of practice in acute early pregnancy care services: a scoping review.

The objective of this scoping review was to investigate and describe what is reported on the role and scope of practice of midwives and registered nurses providing care for women with pregnancy complications under 20 weeks' gestation in acute clinical settings in Australia. In many high-income countries, women experiencing unexpected complications in early pregnancy attend an acute care service, such as an emergency department, rather than a maternity or obstetric unit. This service structure can impact the care women receive, and determine who provides it. Women and their partners, who are often experiencing emotional distress, have reported difficult experiences when accessing acute services, particularly emergency departments, which are not traditionally staffed by midwives. The role and scope of practice of both midwives and registered nurses providing acute early pregnancy care in most high-income countries, including Australia, is poorly reported. Documenting this area of practice is an important first step in facilitating ongoing research in this important aspect of pregnancy care. Published and gray literature that described the role and scope of practice of midwives and/or registered nurses providing care in acute early pregnancy settings in Australia were considered for this review. A scoping review of the literature was conducted following JBI methodological guidance and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) checklist. A 3-step search strategy was conducted to explore evidence from databases and search engines, gray literature sources, and selected reference lists. After screening, data were extracted from records selected for the final review, mapped, and analyzed using content analysis. The evidence reviewed (n=23) included primary research studies, conference abstracts, and gray literature, such as clinical guidance documents, academic theses, and websites from January 2008 to October 2023. The most common setting for care provision was the emergency department. Midwives' and registered nurses' roles and scope of practice in acute early pregnancy care in Australia can be summarized into 4 areas: physical care, psychosocial support, care co-ordination, and communication. Women's access to midwifery care at this time in pregnancy appears to be limited. Registered nurses, usually employed in emergency departments, have the most prominent role and scope in the provision of care for women with acute early pregnancy complications. Descriptions of midwives' practice focuses more on psychosocial support and follow-up care, particularly in early pregnancy assessment service models. This review highlights the inconsistency in midwives' and registered nurses' roles and scope in acute early pregnancy in Australia, a finding which is relevant to other international settings. Both professions could further fulfill role and scope capacity in the provision of supportive, individualized, and timely care for women and families accessing a range of acute early pregnancy services. Emergency departments are the usual practice domain of registered nurses who may be limited in terms of the scope of care they can provide to women with early pregnancy complications. Leaders of the midwifery profession should conduct further research into innovative service models that embed a role for midwives in all settings that provide care for pregnant women, regardless of gestation.

Analysis of copy number variants detected by sequencing in spontaneous abortion.

The incidence of spontaneous abortion (SA), which affects approximately 15-20% of pregnancies, is the most common complication of early pregnancy. Pathogenic copy number variations (CNVs) are recognized as potential genetic causes of SA. However, CNVs of variants of uncertain significance (VOUS) have been identified in products of conceptions (POCs), and their correlation with SA remains uncertain. Of 189 spontaneous abortion cases, trisomy 16 was the most common numerical chromosome abnormality, followed by monosomy X. CNVs most often occurred on chromosomes 4 and 8. Gene Ontology and signaling pathway analysis revealed significant enrichment of genes related to nervous system development, transmembrane transport, cell adhesion, and structural components of chromatin. Furthermore, genes within the VOUS CNVs were screened by integrating human placental expression profiles, PhyloP scores, and Residual Variance Intolerance Score (RVIS) percentiles to identify potential candidate genes associated with spontaneous abortion. Fourteen potential candidate genes (LZTR1, TSHZ1, AMIGO2, H1-4, H2BC4, H2AC7, H3C8, H4C3, H3C6, PHKG2, PRR14, RNF40, SRCAP, ZNF629) were identified. Variations in LZTR1, TSHZ1, and H4C3 may contribute to embryonic lethality. CNV sequencing (CNV-seq) analysis is an effective technique for detecting chromosomal abnormalities in POCs and identifying potential candidate genes for SA.

Primary cilia abnormalities participate in the occurrence of spontaneous abortion through TGF-β/SMAD2/3 signaling pathway.

Spontaneous abortion is the most common complication in early pregnancy, the exact etiology of most cases cannot be determined. Emerging studies suggest that mutations in ciliary genes may be associated with progression of pregnancy loss. However, the involvement of primary cilia on spontaneous abortion and the underlying molecular mechanisms remains poorly understood. We observed the number and length of primary cilia were significantly decreased in decidua of spontaneous abortion in human and lipopolysaccharide (LPS)-induced abortion mice model, accompanied with increased expression of proinflammatory cytokines interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α. The length of primary cilia in human endometrial stromal cell (hESC) was significantly shortened after TNF-α treatment. Knocking down intraflagellar transport 88 (IFT88), involved in cilia formation and maintenance, promoted the expression of TNF-α. There was a reverse regulatory relationship between cilia shortening and TNF-α expression. Further research found that shortened cilia impair decidualization in hESC through transforming growth factor (TGF)-β/SMAD2/3 signaling. Primary cilia were impaired in decidua tissue of spontaneous abortion, which might be mainly caused by inflammatory injury. Primary cilia abnormalities resulted in dysregulation of TGF-β/SMAD2/3 signaling transduction and decidualization impairment, which led to spontaneous abortion.

Cytochrome c oxidase IV isoform 1 (COX4-1) regulates the proliferation, migration and invasion of trophoblast cells via modulating mitochondrial function

IntroductionSpontaneous miscarriage is a common complication of early pregnancy. Previous studies have shown that mitochondrial function plays an important role in establishment of a successful pregnancy. Cytochrome c oxidase subunit 4 isoform 1 (COX4I1), a component of electron transport chain complex Ⅳ, is required for coupling the rate of ATP production to energetic requirements. However, there is very limited research on its role in trophoblast biology and how its dysfunction may contribute to spontaneous miscarriage. MethodsPlacental villi (7–10 weeks gestational age) collected from either induced termination of pregnancy or after spontaneous miscarriage were examined for expression of COX4I1. COX4I1 was knocked down by siRNA transfection of primary isolates of EVT cells. Real-time cell analysis (RTCA) and 5-Ethynyl-2′-deoxyuridine (EdU) were used to detect changes in proliferation ability after COX4I1 knockdown of EVT cells. Migration and invasion indices were determined by RTCA. Mitochondrial morphology was observed via MitoTracker staining. Oxidative phosphorylation, ATP production, and glycolysis in COX4I1-deficient cells and controls were assessed by a cellular energy metabolism analyzer (Seahorse). ResultsIn placental villous tissue, COX4I1 expression was significantly decreased in the spontaneous miscarriage group. Knockdown of COX4I1 inhibited EVT cell proliferation, increased the migration and invasion ability and mitochondrial fusion of EVT cells. Mitochondrial respiration and glycolysis were impaired in COX4I1-deficient EVT cells. Knockdown of MMP1 could rescue the increased migration and invasion induced by COX4I1 silencing. DiscussionLow expression of COX4I1 leads to mitochondrial dysfunction in EVT, resulting in altered trophoblast function, and ultimately to pregnancy loss.

Comparison of zinc levels in mothers with and without abortion: A systematic review and meta-analysiss

IntroductionZinc is an essential trace element involved in different physiological functions. During pregnancy, it plays a crucial role in healthy embryogenesis. Abortion is the most severe problem associated with early pregnancy complications. This study aims to compare the levels of Zn in mothers with and without abortion. MethodsThis study is a systematic review and meta-analysis of studies published between 1980 and 2022 in PubMed, Science Direct, Pro Quest, Wiley, Web of Science, and Scopus databases. The search was conducted using both main and Mesh keywords, specifically targeting terms related to abortion, pregnancy loss, and zinc. Heterogeneity in the studies included in the meta-analysis was evaluated using statistical tests such as the chi-square test, I2, and forest plots. Publication bias was assessed using Begg's and Egger's tests. All analyses were conducted using Stata 15, and statistical significance was considered at p < 0.05. ResultsIn general, nine studies were included in this analysis. Based on the results of the meta-analysis, the mean difference in the Zn level between mothers with and without abortion is equal to 193.18 (95 % CI; 107.11 to 279.25, P ≤ 0.001). In other words, the level of Zn in the group of mothers without abortion is 193 units higher than the group of mothers with abortion. The investigation into the comparison of Zn levels in mothers with and without abortion did not reveal any indication of publication bias according to both Begg's test (P-value = 0.858) and Egger's test (P-value = 0.270). Conclusionthe study findings indicate a significant association between lower levels of Zn in mothers with abortion compared to mothers without abortion. This suggests that a higher level of Zn may have a preventive effect on the occurrence of abortion in pregnant women. The data also highlights the positive role of trace metals, particularly Zn, in influencing pregnancy outcomes and suggests that maintaining adequate levels of Zn may reduce the likelihood of abortion occurrence, along with other contributing factors. It is important to note that further research, including prospective cohort and experimental studies, is needed to provide more substantial evidence and strengthen these findings.

Determinants of Mortality in Primigravida in Peoples Medical College Nawabshah.

Objective: To determine the determinants of maternal mortality in primigravida. Methodology: This cross-sectional, descriptive study was conducted from June 2023 to Dec 2023 at the department of Gynecology and Obstetrics of Peoples University of Medical &amp; Health Sciences for women, Nawabshah; a tertiary care center. We studied overall causes of death (direct and indirect) during pregnancy, delivery, and puerperium. Those patients who died after admission were included and analyzed on specially designed proforma. Information collected from hospital records/patient attendants. The reason for admission, status at arrival, cause of death, and potential variables answerable for death were recognized. Data including age, booking status, parity, gestational age, and relevant variables from the current pregnancy, along with the traveling distance from the clinic, was recorded on Performa, and analyses were done on SPSS adaptation 25. Results: During study period 43 maternal deaths occurred in their first pregnancy. The live birth rate was 10020. MMR counted to 429 per lac live birth. Most frequent death occurs at 19 years of age, from the rural population (62%), the majority un-booked (72%), history of domestic violence (48%) was not uncommon. Among these primigravida; 60% having no formal education, 65% were referral cases presented with obstetrical complication and in labor (34.9%). Almost all deaths were due to direct causes (99%). The highest contribution was by hemorrhage 39.5% (PPH=27.9%+ APH 11.6%), followed by sepsis (27.9%), pre-eclampsia/ eclampsia (18.6%), pulmonary embolism (7%), while 4.7% deaths due to unsafe abortion in early pregnancy complications. We found only 2.3% of deaths due to indirect causes. CONCLUSION: It is crucial to highlight that tackling maternal mortality requires a comprehensive strategy, which encompasses enhancing healthcare infrastructure, guaranteeing access to high-quality prenatal and obstetric care, advocating for education and awareness, and tackling social determinants of health. Recognizing and dealing with these factors can help decrease maternal mortality rates for all expectant mothers, including primigravidae. Key words: Primigravida, Maternal Mortality Rate, antenatal care, Obstetric emergency.

Changes in Maternal Heart Rate Variability and Photoplethysmography Morphology after Corticosteroid Administration: A Prospective, Observational Study.

Background: Owing to the association between dysfunctional maternal autonomic regulation and pregnancy complications, assessing non-invasive features reflecting autonomic activity-e.g., heart rate variability (HRV) and the morphology of the photoplethysmography (PPG) pulse wave-may aid in tracking maternal health. However, women with early pregnancy complications typically receive medication, such as corticosteroids, and the effect of corticosteroids on maternal HRV and PPG pulse wave morphology is not well-researched. Methods: We performed a prospective, observational study assessing the effect of betamethasone (a commonly used corticosteroid) on non-invasively assessed features of autonomic regulation. Sixty-one women with an indication for betamethasone were enrolled and wore a wrist-worn PPG device for at least four days, from which five-minute measurements were selected for analysis. A baseline measurement was selected either before betamethasone administration or sufficiently thereafter (i.e., three days after the last injection). Furthermore, measurements were selected 24, 48, and 72 h after betamethasone administration. HRV features in the time domain and frequency domain and describing heart rate (HR) complexity were calculated, along with PPG morphology features. These features were compared between the different days. Results: Maternal HR was significantly higher and HRV features linked to parasympathetic activity were significantly lower 24 h after betamethasone administration. Features linked to sympathetic activity remained stable. Furthermore, based on the PPG morphology features, betamethasone appears to have a vasoconstrictive effect. Conclusions: Our results suggest that administering betamethasone affects maternal autonomic regulation and cardiovasculature. Researchers assessing maternal HRV in complicated pregnancies should schedule measurements before or sufficiently after corticosteroid administration.

Early HbA1c Levels as a Predictor of Adverse Obstetric Outcomes: A Systematic Review and Meta-Analysis.

Background: The objective was to assess the association between early HbA1c levels and pregnancy complications and whether this relationship is affected when HbA1c thresholds are greater than or less than 39 mmol/mol (5.7%). Methods: Electronic searches of the MEDLINE and EMBASE databases up to October 2022 were conducted. We included retrospective and prospective observational studies. The inclusion criteria were as follows: HbA1c measurements taken at <20 weeks' gestation, singleton pregnancy, and no pre-existing diabetes mellitus. Results: We assessed the certainty of the evidence with the GRADE system. We determined the proportion of patients in each group who met the criteria for obstetrical outcomes and pooled data into two subgroups according to the HbA1c threshold: <39 mmol/mol or >39 mmol/mol (5.7%). Sixteen studies with a total of 43,627 women were included. An association between elevated early HbA1c levels and pre-eclampsia, large for gestational age (LGA), macrosomia, and preterm delivery (RR 2.02, 95% CI 1.53-2.66; RR 1.38, 95% CI 1.15-1.66; RR 1.40, 95% CI 1.07-1.83; and RR 1.67, 95% CI 1.39-2.0, respectively) was shown, with a moderate-high grade of certainty. According to the subgroup analysis of all studies, LGA, pre-eclampsia, and labour induction were associated with elevated HbA1c levels only in studies using an HbA1c threshold >39 mmol/mol (5.7%). The association between HbA1c levels and premature birth was statistically significant in studies using both higher and lower HbA1c thresholds. Conclusions: Women with high early HbA1c levels below the range of diabetes presented an increased risk of pregnancy complications such as macrosomia, LGA, and pre-eclampsia. An early HbA1c threshold of >39 mmol/mol (5.7%) showed the strongest association with pregnancy complications.

The effect of laparoscopic ovarian drilling on pregnancy outcomes in polycystic ovary syndrome women with more than 2 in-vitro fertilization cycle failures: A pilot RCT.

Background: The effect of laparoscopic ovarian drilling (LOD) before in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI) cycles on pregnancy outcomes is an unclear and challenging subject. Objective: To evaluate the impact of LOD before IVF/ICSI cycles on controlled ovarian stimulation and pregnancy outcomes in polycystic ovary syndrome (PCOS) women with a history of more than 2 IVF failures. Materials and Methods: In this randomized clinical trial, women with PCOS diagnosis who referred to Arash Women's hospital, Tehran, Iran for IVF/ICSI cycle from August 2015-January 2018 were evaluated. Eligible participants were allocated into 2 groups randomly (n = 17/each group). The participants in the LOD group (intervention) were treated with laparoscopic couture, and after one month, they underwent IVF/ICSI cycles using the gonadotropin-releasing hormone antagonist protocol. The control group had no intervention. The oocyte and embryo qualities, ovarian hyperstimulation syndrome rate, the rates of chemical and clinical pregnancy and early miscarriage, live birth, and pregnancy complications, were compared between groups. Results: Finally, 34 participants were evaluated. The controlled ovarian stimulation outcomes were similar between groups. The ovarian hyperstimulation syndrome rate in the LOD group was significantly lower than in the control group (p = 0.04). One case of spontaneous pregnancy was reported in the LOD group. No significant difference was observed between groups in clinical pregnancy, miscarriage, and live birth rates. The rates of pregnancy complications (gestational diabetes mellitus, preeclampsia, and preterm birth) were similar between groups. Conclusion: Performing LOD before IVF/ICSI cycles did not improve the pregnancy outcomes in PCOS women, a clinical trial with a larger sample size is needed to prove these results.
