RESUMEN

AIMS/HYPOTHESIS: Dietary patterns characterised by high intakes of vegetables may lower the risk of pre-eclampsia and premature birth in the general population. The effect of dietary patterns in women with type 1 diabetes, who have an increased risk of complications in pregnancy, is not known. The aim of this study was to investigate the relationship between dietary patterns and physical activity during pregnancy and maternal complications and birth outcomes in women with type 1 diabetes. We also compared dietary patterns in women with and without type 1 diabetes. METHODS: Diet was assessed in the third trimester using a validated food frequency questionnaire in participants followed prospectively in the multi-centre Environmental Determinants of Islet Autoimmunity (ENDIA) study. Dietary patterns were characterised by principal component analysis. The Pregnancy Physical Activity Questionnaire was completed in each trimester. Data for maternal and birth outcomes were collected prospectively. RESULTS: Questionnaires were completed by 973 participants during 1124 pregnancies. Women with type 1 diabetes (n=615 pregnancies with dietary data) were more likely to have a 'fresh food' dietary pattern than women without type 1 diabetes (OR 1.19, 95% CI 1.07, 1.31; p=0.001). In women with type 1 diabetes, an increase equivalent to a change from quartile 1 to 3 in 'fresh food' dietary pattern score was associated with a lower risk of pre-eclampsia (OR 0.37, 95% CI 0.17, 0.78; p=0.01) and premature birth (OR 0.35, 95% CI 0.20, 0.62, p<0.001). These associations were mediated in part by BMI and HbA1c. The 'processed food' dietary pattern was associated with an increased birthweight (ß coefficient 56.8 g, 95% CI 2.8, 110.8; p=0.04). Physical activity did not relate to outcomes. CONCLUSIONS/INTERPRETATION: A dietary pattern higher in fresh foods during pregnancy was associated with sizeable reductions in risk of pre-eclampsia and premature birth in women with type 1 diabetes.

RESUMEN

Aberrant long non-coding RNA (lncRNA) expression has been shown to be involved in the pathological process of pre-eclampsia (PE), yet only a small portion of lncRNAs has been characterized concerning the function and molecular mechanisms involved in PE. This study aimed to investigate the regulatory mechanism of the lncRNA AC092100.1 (AC092100.1) in angiogenesis in PE. In our study, bioinformatics analysis was performed to screen for differentially expressed lncRNAs between normal subjects and PE patients. The levels of AC092100.1 in placental tissues of patients with or without PE were validated using qRT-PCR. The effect of AC092100.1 overexpression on the proliferation, migration, and tube formation of human umbilical vein endothelial cells (HUVECs) was investigated. The binding of AC092100.1 and YT521-B homology domain-containing 2 (YTHDC2) was predicted and verified. The effect of AC092100.1/YTHDC2 on the expression of vascular endothelial growth factor-A (VEGFA) in HUVECs was determined. Finally, a PE mice model was conducted. Fetal mouse growth, the abundance of mesenchymal morphology markers, including hypoxia-inducible factor 1-alpha (HIF-1α), soluble fms-like tyrosine kinase-1 (sFlt-1), soluble endoglin (sEng), Slug, and Vimentin, and endothelial markers, including placental growth factor (PLGF), CD31, and vascular endothelial (VE)-cadherin, in placental tissues were assessed. Here, we found that AC092100.1 was abnormally downregulated in placental tissues from PE patients. We established that AC092100.1 overexpression promoted HUVEC proliferation, migration, and tube formation in vitro. Mechanistically, AC092100.1 induced the accumulation of YTHDC2 and VEGFA through binding to YTHDC2 in HUVECs. Inhibition of YTHDC2 or VEGFA reversed AC092100.1-promoted tube formation. AC092100.1 overexpression contributed to alleviating fetal growth disorder, decreased levels of sEng, HIF-1α, sFlt-1, Slug, and Vimentin, and increased levels of VEGFA, PLGF, CD31, and VE-cadherin in PE mice. Our findings provided evidence supporting the role of the AC092100.1/YTHDC2/VEGFA axis in regulating angiogenesis, which demonstrated a therapeutic pathway for PE targeting angiogenesis.

RESUMEN

Background: Stunting can be prevented by early detection when the mother is pregnant. Early detection can be carried out by looking for risk factors of stunting during pregnancy so that interventions can be early detected. This study aims to assess complications during pregnancy (disease and infection) and risk factors associated with stunting. Materials and Methods: The type of research was observational analytic with a case-control design on 450 mothers who were selected with simple random sampling (150 mothers who have stunting babies aged 0-2 months and 300 mothers who have not stunting babies aged 0-2 months in Malang Regency, Indonesia. This study used secondary data by looking at medical records, namely, laboratory examinations in the mother's book and cohort records at the public health center. This study was conducted from December 2021 to August 2022. Bivariate analysis with Chi-square and multivariate logistic regression was carried out to determine the variables that most influenced the incidence of stunting. Results: The results of multivariate analysis with logistic regression of maternal complications during pregnancy, which are a risk as a factor causing stunting, are Sexually Transmitted Infections (STIs) (Odds Ratio [OR]: 6.36; 95% Confidence Interval [CI]: 2.97-13.62), coronavirus disease 2019 (COVID-19) accompanied by pneumonia (OR: 5.12; 95% CI: 1.87-14.052), human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (OR: 4.63; 95% CI: 1.10-19.59), hepatitis B (OR: 3.97; 95% CI: 1.253-12.565), pre-eclampsia (OR: 3.88; 95% CI: 1.81-8.30), and heart disease (OR: 3.373; 95% CI: 0.99-11.40). Conclusions: After recognizing the maternal factors that cause stunting, intervention should immediately be carried out on pregnant women with diseases (pre-eclampsia and heart disease) and infections (STI, COVID-19 + pneumonia, HIV/AIDS, and hepatitis B) to prevent stunting early.

RESUMEN

The aim of the study is to analyze ventricular-vascular properties with different ventricular-arterial coupling (VAC) ratio in the preeclamptic women. Seventy-seven pregnant women with preeclampsia and eighty-nine with normal pregnancy were performed echocardiography. VAC was defined as the ratio between aortic elastance (Ea) and left ventricular (LV) end-systolic elastance (Ees). Using the VAC value of 0.8 as the cut-off near uncoupling, the preeclampsia cases were divided into two subgroups: VAC ratio ≥ 0.8 and <0.8. Cardiac structure and function, VAC properties, as well as four components of the LV pressure-strain loop, including global myocardial work index (GWI), constructive work (GCW), wasted work (GWW), and work efficiency (GWE) were determined. The preeclampsia with VAC ≥ 0.8 had an enlarger indexed ventricular volume and a thicker relative ventricular wall than the VAC < 0.8. The Ees significantly increased in the subgroup with VAC < 0.8 and decreased in the VAC ≥ 0.8, while the Ea increased in both of them. The preeclampsia with VAC ≥ 0.8 showed an obvious augmentation in GWI, GCW and GWE, along with a similar GWW compared to those with VAC < 0.8. There were variable relationships between the LV pressure-strain components and VAC properties. Thus, the preeclampsia with VAC ≥ 0.8 undergoes a more adverse remodeling and a greater impact on cardiac contractility. The increased stiffness of the heart and arterial system, and increased resistance of peripheral vessels net lead to the deteriorative ventricular efficiency with elevated myocardial oxygen consumption during a preeclampsia pregnancy.

RESUMEN

BACKGROUND: Pre-eclampsia is a syndrome that chiefly includes the development of new-onset hypertension and proteinuria after 20 weeks of pregnancy. Pre-eclampsia is one of the major causes of mortality and morbidity in Nepal. Hyperhomocysteinemia may be a cause of the endothelial dysfunction provoked by oxidative stress in pre-eclampsia. This study was designed to evaluate the association of homocysteine with Vitamin B12 and folate in patients with pre-eclampsia. METHOD: An observational cross sectional study was performed in the Gynecology and Obstetrics Department of TUTH involving seventy two subjects with pre-eclampsia. Blood pressure, urinary protein levels, serum homocysteine, Vitamin B12 and folate levels were compared in both mild and severe forms of pre-eclampsia. Concentration of Vitamin B12 and folate were measured using Vitros ECI and homocysteine was measured using CLIA. SPSS 23.0 was used to analyze the data. Tests were performed with Mann Whitney Test and Spearman's rank correlation test. A p-value < 0.05 was considered statistically significant. RESULTS: This study showed no significant difference in age and weeks of gestation in both mild and severe forms of pre-eclampsia. Mean concentration of homocysteine was higher (13.1 ± 6.4 micromol/L) in severe Pre-eclampsia as compared to mild cases (7.6 ± 2.8 micromol/L). Mean concentration of folate was lower in severe cases (35.4 ± 24.1 micromol/L) when compared with mild cases of pre-eclampsia (57 ± 23.4 micromol/L). CONCLUSION: Homocysteine levels were increased in severe Pre-eclampsia when compared with mild pre-eclampsia and this finding can be used to predict and prevent complications in patients with pre-eclampsia.

RESUMEN

Prevention of pregnancy complications related to the "great obstetrical syndromes" (preeclampsia, fetal growth restriction, spontaneous preterm labor, and stillbirth) is a global research and clinical management priority. These syndromes share many common pathophysiological mechanisms that may contribute to altered placental development and function. The resulting adverse pregnancy outcomes are associated with increased maternal and perinatal morbidity and mortality and increased post-partum risk of cardiometabolic disease. Maternal nutritional and environmental factors are known to play a significant role in altering bidirectional communication between fetal-derived trophoblast cells and maternal decidual cells and contribute to abnormal placentation. As a result, lifestyle-based interventions have increasingly been recommended before, during, and after pregnancy, in order to reduce maternal and perinatal morbidity and mortality and decrease long-term risk. Antenatal screening strategies have been developed following extensive studies in diverse populations. Multivariate preeclampsia screening using a combination of maternal, biophysical, and serum biochemical markers is recommended at 11-14 weeks' gestation and can be performed at the same time as the first-trimester ultrasound and blood tests. Women identified as high-risk can be offered prophylactic low dose aspirin and monitored with angiogenic factor assessment from 22 weeks' gestation, in combination with clinical assessment, serum biochemistry, and ultrasound. Lifestyle factors can be reassessed during counseling related to antenatal screening interventions. The integration of lifestyle interventions, pregnancy screening, and medical management represents a conceptual advance in pregnancy care that has the potential to significantly reduce pregnancy complications and associated later life cardiometabolic adverse outcomes.

RESUMEN

Pregnancy Hypertensive Disorders (PHD), particularly Preeclampsia (PE), are significant contributors to maternal-fetal morbidity and mortality, with chronic arterial hypertension (CH) being a major risk factor. The prevalence of CH has risen alongside obesity and advanced maternal age. While antihypertensive treatment mitigates adverse pregnancy outcomes, the duration of effective blood pressure (BP) control, termed Time in Therapeutic Range (TTR), has not been extensively studied in pregnant women. TTR, reflecting the proportion of time BP remains within target ranges, predicts long-term cardiovascular and renal events in the general population but remains unexplored in pregnancy. This study investigates the association between TTR, assessed through office BP (OBP) and ambulatory BP monitoring (ABPM), and PE development in pregnant women with CH. In a retrospective longitudinal study, data from 166 pregnant women with HA referred to our hospital analyzed. BP was measured using OBP and ABPM from 10 weeks of gestation, with TTR calculated as the percentage of visits where BP remained within target ranges. The study defined four TTR control groups: 0%, 33%, 50-66%, and 100%. Results showed that 28% of the participants developed PE, with a higher incidence correlating with lower TTR in ABPM. TTR in ABPM was a significant predictor of PE risk, with the best-controlled group (100% TTR) demonstrating a 92% reduced risk compared to those with 0% TTR. The agreement between OBP and ABPM TTR was low, emphasizing the importance of ABPM for accurate BP monitoring in pregnancy. This study indicates that integrating ABPM for TTR assessment in high-risk pregnancies has the potential to reduce maternal and fetal complications.

RESUMEN

OBJECTIVE: The aim of the present study was to determine the risk factors for patients with pre-eclampsia (PE) with severe features to develop hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome and to design a prediction score model that incorporates these risk factors. METHODS: A retrospective cohort study was conducted at a tertiary university-affiliated medical center between 2011 and 2019. The study population comprised patients diagnosed with PE with severe features, divided into two groups: those with HELLP syndrome (study group) and those without (control group). A logistic regression was employed to identify independent predictors of HELLP syndrome. A predictive model for the occurrence of HELLP syndrome in the context of PE with severe features was developed using a receiver operating characteristic curve analysis. RESULTS: Overall, 445 patients were included, of whom 69 patients were in the study group and 376 in the control group. A multivariate logistic analysis regression showed that maternal age <40 (OR = 2.28, 95% CI: 1.13-5.33, P = 0.045), nulliparity (OR = 2.22, 95% CI: 1.14-4.88, P = 0.042), mild hypertension (OR = 2.31, 95% CI: 1.54-4.82, P = 0.019), epigastric pain (OR = 3.41, 95% CI: 1.92-7.23, P < 0.001) and placental abruption (OR = 6.38, 95% CI: 1.29-35.61, P < 0.001) were independent risk factors for HELLP syndrome. A prediction score model reached a predictive performance with an area under the curve of 0.765 (95% CI: 0.709-0.821). CONCLUSION: This study identified several key risk factors for developing HELLP syndrome among patients with PE with severe features and determined that a prediction score model has the potential to aid clinicians in identifying high risk patients.

RESUMEN

Background: Systemic lupus erythematosus (SLE) is associated with adverse pregnancy outcome (APO). However, the genetic causality of this association remains unclear. In this study, Mendelian randomization (MR) was used to explore the potential causal relationship between SLE and APO risk. Methods: We selected 45 single nucleotide polymorphisms (SNPs) associated with SLE from published genome-wide association studies (GWAS). APO's statistics are obtained from the GWAS database. MR estimates were performed using the inverse variance-weighted (IVW) method, the MR-Egger method, and the weighted median (WM) method. Sensitivity analysis was performed using Cochran's Q test, MR-Egger intercept, MR-pleiotropic residual and outlier method, stay-one analysis and funnel plot. Results: The results showed a causal relationship between SLE and pre-eclampsia (OR = 1.036, 95 % confidence interval 1.006 to 1.068, P = 0.019), and no significant causal relationship was found between SLE and other adverse pregnancy outcomes, including postpartum hemorrhage, placental abruption, spontaneous abortion, premature rupture of membranes, fetal distress, gestational diabetes mellitus. These findings were robust in several sensitivity analyses. Conclusion: This MR study demonstrated the causal effect of SLE on preeclampsia. It provides important clues for identifying and early predicting risk factors for preeclampsia.

RESUMEN

Pre-eclampsia (PE) is a severe pregnancy complication that is more common in patients with systemic lupus erythematosus (SLE). Although the exact causes of these conditions are not fully understood, the immune system plays a key role. To investigate the connection between SLE and PE, we analyzed genes associated with SLE that may contribute to the development of PE. We collected 9 microarray data sets from the NCBI GEO database and used Limma to identify the differentially expressed genes (DEGs). In addition, we employed weighted gene co-expression network analysis (WGCNA) to pinpoint the hub genes of SLE and examined immune infiltration using Cibersort. By constructing a protein-protein interaction (PPI) network and using CytoHubba, we identified the top 20 PE hub genes. Subsequently, we created a nomogram and conducted a receiver operating characteristic (ROC) analysis to predict the risk of PE. Our analysis, including gene set enrichment analysis (GSEA) and PE DEGs enrichment analysis, revealed significant involvement in placenta development and immune response. Two pivotal genes, BCL6 and MME, were identified, and their validity was confirmed using 5 data sets. The nomogram demonstrated good diagnostic performance (AUC: 0.82-0.96). Furthermore, we found elevated expression levels of both genes in SLE peripheral blood mononuclear cells (PBMCs) and PE placental specimens within the case group. Analysis of immune infiltration in the SLE data set showed a strong positive correlation between the expression of both genes and neutrophil infiltration. BCL6 and MME emerged as crucial genes in lupus-related pregnancies associated with the development of PE, for which we devised a nomogram. These findings provide potential candidate genes for further research in the diagnosis and understanding of the pathophysiology of PE.

RESUMEN

Hypertension during pregnancy affects up to 10% of pregnancies and is associated with significant cardiovascular morbidity and mortality. In the short-term it can result in pre-eclampsia, haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome, or even hypertension associated acute heart failure, all of which may necessitate pre-term delivery to prevent maternal or neonatal death. In the long term, a history of gestational hypertension and pre-eclampsia significantly increases the risk of future cardiovascular disease including chronic hypertension, coronary artery disease, heart failure and stroke. This review explores our current level of knowledge of the phenotypes of heart failure, paying particular attention to those specific to women, and the role of pregnancy and non-pregnancy related risk factors in the development of this condition. We discuss why women with hypertensive pregnancy may be disproportionately affected by heart failure with preserved ejection fraction (HFpEF) and whether a unique phenotype of heart failure unique to hypertensive pregnancy exists. Finally, we explore how future cardiovascular risk may be predicted based on cardiac remodelling during or after pregnancy and suggest potential areas of further research in the field.

RESUMEN

Hypertensive disorders of pregnancy are the second most common cause of maternal deaths worldwide. Metabolic syndrome is recognized as one of the risk factors for pre-eclampsia. A recent study revealed a high prevalence of metabolic syndrome in the United Arab Emirates (UAE), particularly amongst Emirati women compared with global estimates. This finding raises the possibility that the prevalence of pre-eclampsia in the region may also be higher as research is increasingly demonstrating an association between pre-eclampsia and metabolic syndrome. We therefore conducted this scoping review of the literature to investigate the nature and extent of studies evaluating the prevalence of pre-eclampsia within the Middle East region to enable subsequent comparison of these findings with the global burden of pre-eclampsia, objectively identify gaps in the literature and inform the design of future studies to address these gaps. PubMed and Scopus were used to extract studies published over the last 20 years (2003-2023). The search terms used included ("Pre-eclampsia" AND "Prevalence") OR ("Hypertension in pregnancy" AND "Prevalence") OR ("Pregnancy" AND "Pre-eclampsia") OR ("Pre-eclampsia" AND "Epidemiology"). We limited our studies to those from the Middle East (ME). A total of 556 relevant articles were identified following which 11 were shortlisted for review. There were four studies from Iran, two from Saudi Arabia, two from Qatar, one from Jordan, and one from Bahrain. The remaining study included 29 countries from Africa, Asia, Latin America, and the Middle East of which data from Jordan, Lebanon, the Occupied Palestinian Territory, and Qatar were included. There were four retrospective, two cross-sectional, and two cohort studies, one prospective study, one meta-analysis, and one descriptive-analytical study. The prevalence of pre-eclampsia in the studies ranged from 0.17 to 5%. We did not find any study investigating the prevalence of pre-eclampsia in the United Arab Emirates. Based on our findings, we conclude that there is a significant scarcity of research in this area, especially within the Middle East, and notably an absence of studies specifically pertaining to the UAE. Consequently, we assert that there is a pressing requirement for additional research to evaluate the prevalence of pre-eclampsia in the region.

RESUMEN

BACKGROUND: This systematic review explores the level of oxidative stress (OS) markers during pregnancy and their correlation with complications. Unlike previous studies, it refrains from directly investigating the role of OS but instead synthesises data on the levels of these markers and their implications for various pregnancy-related complications such as preeclampsia, intrauterine growth restrictions, preterm premature rupture of membranes, preterm labour, gestational diabetes mellitus and miscarriages. METHOD: STUDY DESIGN: Utilizing a systematic review approach, we conducted a comprehensive search across databases, including MEDLINE, CINAHL (EBSCOhost), ScienceDirect, Web of Science, and SCOPUS. Our search encompassed all publication years in English. RESULTS: After evaluating 54,173 records, 45 studies with a low risk of bias were selected for inclusion. This systematic review has underscored the importance of these markers in both physiological and pathological pregnancy states such as preeclampsia, intrauterine growth restrictions, preterm premature rupture of membranes, preterm labour, gestational diabetes mellitus and miscarriages. CONCLUSION: This systematic review provides valuable insights into the role of OS in pregnancy and their connection to complications. These selected studies delved deeply into OS markers during pregnancy and their implications for associated complications. The comprehensive findings highlighted the significance of OS markers in both normal and pathological pregnancy conditions, paving the way for further research in this field.

RESUMEN

Pre-eclampsia (PE) is classified as pregnancy-specific hypertensive disease and responsible for severe fetal and maternal morbidity and mortality, which influenced an approximate 3 âˆ¼ 8 % of all pregnancies in both developed and developing countries. However, the exact pathological mechanism underlying PE has not been elucidated and it is urgent to find innovate pharmacotherapeutic agents for PE. Recent studies have reported that a crucial part of the etiology of PE is played by placental oxidative stress. Therefore, to treat PE, a possible treatment approach is to mitigate the placental oxidative stress. Alpinumisoflavone (AIF) is a prenylated isoflavonoid originated in mandarin melon berry called Cudrania tricuspidate, and is well known for its versatile pharmacotherapeutic properties, including anti-fibrotic, anti-inflammatory, anti-tumor, and antioxidant activity. However, protective property of AIF on extravillous trophoblast (EVT) under placental oxidative stress has not been elucidated yet. Therefore, we assessed stimulatory effects of AIF on the viability, invasion, migration, mitochondria function in the representative EVT cell line, HTR-8/SVneo cell. Moreover, protective activities of AIF from H2O2 were confirmed, in terms of reduction in apoptosis, ROS production, and depolarization of mitochondrial membrane. Furthermore, we confirmed the direct interaction of AIF with sirtuin1 (SIRT1) using molecular docking analysis and SIRT1-mediated signaling pathways associated with the protective effects of AIF on HTR-8/SVneo cells under oxidative stress. Finally, beneficial efficacy of AIF against oxidative stress was further confirmed using BeWo cells, syncytiotrophoblast cell lines. These results suggest that AIF may ameliorate H2O2-induced intracellular damages through SIRT1 activation in human trophoblast cells.

RESUMEN

OBJECTIVE: To explore UK-based clinicians' knowledge of long-term cardiovascular disease (CVD) risks after pre-eclampsia and capture current risk management practice. STUDY DESIGN: A voluntary online survey was designed to explore clinicians' perception and management of CVD risks after pre-eclampsia. Distribution occurred May-July 2022 via social media and email. The survey assessed awareness of pre-eclampsia's association with future CVD, knowledge of published guidelines on CVD risk management after pre-eclampsia, and current practice of risk-reduction counselling. Results were analysed descriptively. MAIN OUTCOME MEASURE: Clinician knowledge of postpartum cardiovascular risk and management following pre-eclampsia. RESULTS: Of 240 respondents, 72 were midwives, 46 obstetricians, 8 cardiologists, and 114 general practitioners (GPs). Most clinicians knew that pre-eclampsia increases the risk of chronic hypertension (89 %) and stroke (75 %). Awareness was worse for heart failure (47 %) and peripheral vascular disease (55 %). Obstetricians provide CVD risk-reduction counselling to women with pre-eclampsia most frequently: 43 % always counsel and 27 % often counsel. Most other clinicians never counsel patients (midwives: 76 %, cardiologists: 75 %, GPs: 62 %). Most clinicians (84 %) were not aware of CVD risk management guidance after pre-eclampsia and 75 % of cardiologists and GPs never consider pre-eclampsia when assessing cardiovascular risk. Almost all clinicians (91 %) wished for greater education on the topic. CONCLUSIONS: This study presents the first assessment of cardiovascular risk awareness after pre-eclampsia amongst UK-based clinicians. Although most knew pre-eclampsia increases CVD risk, patient counselling was limited. Targeted educational initiatives are needed to improve the knowledge-to-practice gap and reduce CVD prevalence after pre-eclampsia.

RESUMEN

OBJECTIVE: To compare circulating levels of vascular endothelial growth factor receptor 3 (VEGFR-3) in women with pregnancy-induced hypertension (PIH) and in non-pregnant (NP) and healthy pregnant (HP) women. METHODS: We conducted a case-control study including PIH (n = 135), HP (n = 68), and NP (n = 49) women from southeastern Brazil. PIH were diagnosed according to international guidelines, and defined as gestational hypertension (GH, n = 61) or pre-eclampsia (n = 74). VEGFR-3 was measured in plasma using ELISA. RESULTS: Plasma VEGFR-3 was increased in HP (1207 pg/mL) compared with NP (133 pg/mL) women; however, PIH (729 pg/mL) patients exhibited lower levels than HP women (both p < 0.05). In addition, plasma VEGFR-3 was decreased in pre-eclampsia compared with GH (537 versus 980 pg/mL; p < 0.05). When pre-eclampsia was classified according to different clinical presentations, plasma VEGFR-3 was further decreased in the cases identified as pre-eclampsia with severe features, preterm pre-eclampsia, and pre-eclampsia accompanied by small for gestational age (all p < 0.05). CONCLUSION: Our data indicate reduced circulating VEGFR-3 levels in patients with PIH, specifically in those diagnosed with pre-eclampsia. Moreover, decreased VEGFR-3 was associated with adverse clinical outcomes in pre-eclampsia. These findings expand previous evidence of reduced VEGFR-3 expression in pre-eclampsia. Future studies should investigate whether it can be used as a predictive biomarker and/or therapeutic target for pre-eclampsia.

RESUMEN

Introduction Pregnancies complicated by hypertensive disorders contribute to enormous burden on economy and health-care facilities. Eclampsia is one of the clinical markers of near-miss mortality. To achieve optimal outcomes, efforts should be directed at both periphery and tertiary care levels. This study aimed to compare the feto-maternal outcome in patients presenting with eclampsia and a matched control population. Methodology A comparative observational study was conducted among 70 cases and 70 controls. Detailed history and general and obstetrical examinations were carried out. Data was extracted from case files, labor room, and ICU records. Maternal and fetal outcomes were noted from January 2023 to January 2024. Statistical software STATA 14.2 (StataCorp LLC, College Station, Texas, USA) was used for data analysis. Observational descriptive statistics and chi-square and Fisher extract tests were applied. Results In our study, the incidence of eclampsia was 0.7% (70 per 1000 live births). The maternal mortality rate was 102.8/100000 live births and the perinatal mortality rate was 10.2/ 1000 live births in our study. The study observed a relatively young aged population and a significant bulk of cases belonged to late gestation or post-partum. Events like HELLP syndrome, abruption, liver, and renal failure were found to be frequently linked to eclampsia. Neonatal asphyxia (P-0.005), NICU requirement 41.43% vs 29% (P<0.01) preterm delivery 45.7% vs 14% (P=<0.001), and low birth weight were more commonly observed among the cases than the controls. Conclusions Eclampsia was found to be a significant contributor to elevated rates of morbidity and mortality in mothers and newborns. Poor antenatal care, severe anemia, and late referrals were some of the modifiable risk factors. Health care and economic burden on society is immense due to the significant utilization of intensive care and high dependency units.

RESUMEN

Background: The association between endometriosis and the outcome of pregnancy is one of the interesting topics. Endometriosis-related pain is alleviated with pregnancy; however, it is known to cause adverse outcomes in pregnancy. The main cause is systemic chronic inflammation caused by higher levels of cytokines, growth factors, and angiogenesis factors. Objective: This study aimed to clarify the relationship between endometriosis, deep endometriosis, adenomyosis, surgical treatment, and poor maternal consequences. Materials and Methods: In this case-control study, data from 250 women who gave birth in Hazrat Rasoul Akram hospital, Tehran, Iran from February 2015 to December 2019 was extracted from the hospital information system in January 2020. Participants were divided into 2 groups: 125 women with endometriosis and 125 women without endometriosis. We looked at how endometriosis affected mothers and newborn babies. Data on pregnancy, delivery, and newborns of both groups was extracted. Results: The mean age of participants was 32.74 ± 4.10 and 31.7 ± 5.53 yr in endometriosis and control group, respectively. In terms of pregnancy complications, placenta previa, placenta accreta, placenta abruption, pre-eclampsia, gestational diabetes mellitus, and postpartum hemorrhage remarkably increased in the endometriosis group compared to the control group. Small for gestational age was significantly higher in rectal endometriosis than women without rectal endometriosis (p = 0.03). The neonatal intensive care unit admission rate was notably higher in infants of the endometriosis group compared to controls (40.7% vs. 24.8%, p = 0.009). Conclusion: Our findings showed women with endometriosis are at a higher risk for important adverse maternal outcomes.

RESUMEN

Branch retinal artery occlusion is a rare cause of sudden vision loss. New-onset visual disturbances are considered a severe feature of preeclampsia and an indication for delivery regardless of gestational age. This report describes the management of a primigravida at 31 weeks of gestation, with multiple comorbidities, who presented with preeclampsia and a new dark spot in her vision. After extensive workup, her branch retinal artery occlusion was not attributable to her preexisting comorbidities nor an undiagnosed thrombophilia. Multidisciplinary collaboration and close observation enabled delay of delivery until 34 weeks of gestation without detriment and substantially mitigated the risks of preterm birth. Her visual defect was stable and permanent. This seems to be the first case in the literature to describe branch retinal artery occlusion diagnosed simultaneously with preeclampsia in the third trimester. Branch retinal artery occlusion may not be a severe feature of preeclampsia requiring delivery.
