RESUMEN
INTRODUCTION: We investigated whether structured maternal lifestyle interventions based on Mediterranean diet or stress reduction influence fetal-infant neurodevelopment detected by detailed fetal neurosonography and Ages and Stages Questionnaires 3rd edition (ASQ) at 12 months old. METHODS: This was a secondary analysis of a randomized clinical trial (2017-2020), including 1,221 singleton pregnancies at high risk for small-for-gestational age. Participants were randomized into three groups at 19-23 weeks' gestation: Mediterranean diet intervention, stress reduction program, or usual care. A detailed neurosonography was performed on 881 participants at mean (SD) 33.4 (1.1) weeks' gestation. Neurosonographic measurements were done offline. ASQ was performed on 276 infants at 1 year of corrected age. RESULTS: Biparietal diameter was similar among study groups. Mediterranean diet group fetuses had deeper insula (26.80 [1.68] versus 26.63 [1.75], mm, p = 0.02) and longer corpus callosum (42.98 [2.44] versus 42.62 [2.27], mm, p = 0.04), with a lower rate of suboptimal score infants in ASQ problem-solving domain (6.2 vs. 16.3%, p = 0.03). Stress reduction group fetuses had deeper insula (26.90 [1.75] versus 26.63 [1.75], mm, p = 0.04) and lower rates of suboptimal score infants in ASQ fine motor domain (4.3 vs. 12.8%, p = 0.04), compared to usual care group fetuses. CONCLUSION: Maternal structured intervention during pregnancy of the trial has the potential to modify offspring's neurodevelopment.
RESUMEN
Introduction Congenital malformations of the right atrium are rare heart defects with only a few cases described prenatally. Early diagnosis of these anomalies is becoming increasingly important for proper follow-up and due to the possibility of serious complications such as supraventricular arrhythmia, thromboembolic events, and sudden death. Objective The atrial appendage aneurysm (AAA) is a dilatation of the atrial appendage. It is considered an extremely rare congenital anomaly. However, this condition is clinically significant because it leads to atrial arrhythmias, recurrent emboli, heart failure, and chest pain. In addition, it is possible to recognize AAA prenatally with fetal echocardiography, even if it rarely happens. However, few fetal AAA cases have been reported in the literature. Study Design We report a case of a fetal AAA; diagnosed prenatally and with postnatal confirmation. We undertook a systematic review of studies on fetal AAA to synthesize available knowledge on diagnosing and managing this rare condition. Results A total of eight studies describing 24 patients were identified and analyzed. Conclusion Despite their rarity, fetal atrial appendage aneurysms necessitate early detect on due to associated severe complications. Our findings emphasize the importance of prenatal diagnosis through fetal echocardiography and highlight the need for further research to optimize management strategies and improve outcomes for affected individuals.
RESUMEN
OBJECTIVE: To demonstrate that successful health systems strengthening (HSS) projects have addressed disparities and inequities in maternal and perinatal care in low-income countries. METHODS: A comprehensive literature review covered the period between 1980 and 2022, focusing on successful HSS interventions within health systems' seven core components that improved maternal and perinatal care. RESULTS: The findings highlight the importance of integrating quality interventions into robust health systems, as this has been shown to reduce maternal and newborn mortality. However, several challenges, including service delivery gaps, poor data use, and funding deficits, continue to hinder the delivery of quality care. To improve maternal and newborn health outcomes, a comprehensive HSS strategy is essential, which should include infrastructure enhancement, workforce skill development, access to essential medicines, and active community engagement. CONCLUSION: Effective health systems, leadership, and community engagement are crucial for a comprehensive HSS approach to catalyze progress toward universal health coverage and global improvements in maternal and newborn health.

Fetal growth restriction (FGR) affects 5-10% of pregnancies, is the largest contributor to fetal death, and can have long-term consequences for the child. Implementation of a standard clinical classification system is hampered by the multiphenotypic spectrum of small fetuses with substantial differences in perinatal risks. Machine learning and multiomics data can potentially revolutionize clinical decision-making in FGR by identifying new phenotypes. Herein, we describe a cluster analysis of FGR based on an unbiased machine-learning method. Our results confirm the existence of two subtypes of human FGR with distinct molecular and clinical features based on multiomic analysis. In addition, we demonstrated that clusters generated by machine learning significantly outperform single data subtype analysis and biologically support the current clinical classification in predicting adverse maternal and neonatal outcomes. Our approach can aid in the refinement of clinical classification systems for FGR supported by molecular and clinical signatures.
RESUMEN
OBJECTIVE: To compare maternal and perinatal outcomes of migrant Venezuelan women with local pregnant patients in a Colombian institution in the context of a migratory crisis. STUDY DESIGN: This cross-sectional study included 11 304 deliveries from the Clínica de Maternidad Rafael Calvo in Cartagena de Indias, Colombia, a tertiary referral center on the north coast of Colombia. Data on maternal demographics and perinatal outcomes were obtained by chart review. RESULTS: In total, 595 patients were identified as Venezuelan migrants, and their perinatal outcomes were compared against those of 10 709 local pregnant patients. Despite similar baseline maternal conditions in both groups, poorer prenatal follow-up care (3 [1-5] vs. 5 [4-7] visits; P < 0.001) and severe complications were more common in Venezuelan migrant pregnant patients and their children. In addition, maternal hypertension was significantly more common in migrants (11.4% [68/595] vs. 8.3% [887/10709]; P = 0.009). Furthermore, in the group of pregnant migrant patients, the rates of severe maternal morbidity (13.4% [80/575] vs. 9.45%, [1013/10709]; P = 0.002), neonatal respiratory distress syndrome (22/595 [3.7%] vs. 237/10709 [2.23%]; P = 0.03), and perinatal mortality (11/586 [1.88%] vs. 67/10651 [0.63%]; P = 0.003) were significantly higher than in the local pregnant population. CONCLUSION: Forced migration during pregnancy may be associated with poorer prenatal care, which may predispose women and their newborns to more frequent adverse maternal and perinatal outcomes.

OBJECTIVES: This study was conducted to determine whether bacteria, fungi, or archaea are detected in the amniotic fluid of patients who underwent midtrimester amniocentesis for clinical indications. METHODS: Amniotic fluid samples from 692 pregnancies were tested by using a combination of culture and end-point polymerase chain reaction (PCR) techniques. Intra-amniotic inflammation was defined as an interleukin-6 concentration >2,935 pg/mL. RESULTS: Microorganisms were detected in 0.3% (2/692) of cases based on cultivation, 1.73% (12/692) based on broad-range end-point PCR, and 2% (14/692) based on the combination of both methods. However, most (13/14) of these cases did not have evidence of intra-amniotic inflammation and delivered at term. Therefore, a positive culture or end-point PCR in most patients appears to have no apparent clinical significance. CONCLUSIONS: Amniotic fluid in the midtrimester of pregnancy generally does not contain bacteria, fungi, or archaea. Interpretation of amniotic fluid culture and molecular microbiologic results is aided by the assessment of the inflammatory state of the amniotic cavity. The presence of microorganisms, as determined by culture or a microbial signal in the absence of intra-amniotic inflammation, appears to be a benign condition.

Coronavirus disease-2019 (COVID-19) infection during pregnancy is associated with severe complications and adverse effects for the mother, the fetus, and the neonate. The frequency of these outcomes varies according to the region, the gestational age, and the presence of comorbidities. Many COVID-19 interventions, including oxygen therapy, high-flow nasal cannula, and invasive mechanical ventilation, are challenging and require understanding physiologic adaptations of pregnancy. Vaccination is safe during pregnancy and lactation and constitutes the most important intervention to reduce severe disease and complications.

OBJECTIVE: To evaluate the performance of INTERGROWTH-21st (IG-21st ) and World Health Organization (WHO) fetal growth charts to identify small-for-gestational-age (SGA) and fetal growth restriction (FGR) neonates, as well as their specific risks for adverse neonatal outcomes. METHODS: Multicenter cross-sectional study including 67 968 live births from 10 maternity units across four Latin American countries. According to each standard, neonates were classified as SGA and FGR (birth weight <10th and less than third centiles, respectively). The relative risk (RR) and diagnostic performance for a low APGAR score and low ponderal index were calculated for each standard. RESULTS: WHO charts identified more neonates as SGA than IG-21st (13.9% vs 7%, respectively). Neonates classified as having FGR by both standards had the highest RR for a low APGAR (RR, 5.57 [95% confidence interval (CI), 3.99-7.78]), followed by those who were SGA by both curves (RR, 3.27 [95% CI, 2.52-4.24]), while neonates with SGA identified by WHO alone did not have an additional risk (RR, 0.87 [95% CI, 0.55-1.39]). Furthermore, the diagnostic odds ratio for a low APGAR was higher when IG-21st was used. CONCLUSION: In a population from Latin America, the WHO charts seem to identify more SGA neonates, but the diagnostic performance of the IG-21st charts for low APGAR score and low ponderal index is better.

INTRODUCTION: Preeclampsia is a multi-system disorder unique to pregnancy responsible for a great part of maternal and perinatal morbidity and mortality. The precise pathogenesis of this complex disorder is still unrevealed. METHODS: We examined the pathophysiological pathways involved in early-onset preeclampsia, a specific subgroup representing its most severe presentation, using LC-MS/MS metabolomic analysis based on multi-level extraction of lipids and small metabolites from maternal blood samples, collected at the time of diagnosis from 14 preeclamptic and six matched healthy pregnancies. Statistical analysis comprised multivariate and univariate approaches with the application of over representation analysis to identify differential pathways. RESULTS: A clear difference between preeclamptic and control pregnancies was observed in principal component analysis. Supervised multivariate analysis using orthogonal partial least square discriminant analysis provided a robust model with goodness of fit (R2X = 0.91, p = 0.002) and predictive ability (Q2Y = 0.72, p < 0.001). Finally, univariate analysis followed by 5% false discovery rate correction indicated 82 metabolites significantly altered, corresponding to six overrepresented pathways: (1) aminoacyl-tRNA biosynthesis; (2) arginine biosynthesis; (3) alanine, aspartate and glutamate metabolism; (4) D-glutamine and D-glutamate metabolism; (5) arginine and proline metabolism; and (6) histidine metabolism. CONCLUSION: Metabolomic analysis focusing specifically on the early-onset severe form of preeclampsia reveals the interplay between pathophysiological pathways involved in this form. Future studies are required to explore new therapeutic approaches targeting these altered metabolic pathways in early-onset preeclampsia.
RESUMEN
BACKGROUND: Gestational diabetes mellitus (GDM) is a serious public health issue affecting 9-15% of all pregnancies worldwide. Recently, it has been suggested that extracellular vesicles (EVs) play a role throughout gestation, including mediating a placental response to hyperglycaemia. Here, we investigated the EV-associated miRNA profile across gestation in GDM, assessed their utility in developing accurate, multivariate classification models, and determined the signaling pathways in skeletal muscle proteome associated with the changes in the EV miRNA profile. METHODS: Discovery: A retrospective, case-control study design was used to identify EV-associated miRNAs that vary across pregnancy and clinical status (i.e. GDM or Normal Glucose Tolerance, NGT). EVs were isolated from maternal plasma obtained at early, mid and late gestation (n = 29) and small RNA sequencing was performed. Validation: A longitudinal study design was used to quantify expression of selected miRNAs. EV miRNAs were quantified by real-time PCR (cases = 8, control = 14, samples at three times during pregnancy) and their individual and combined classification efficiencies were evaluated. Quantitative, data-independent acquisition mass spectrometry was use to establish the protein profile in skeletal muscle biopsies from normal and GDM. RESULTS: A total of 2822 miRNAs were analyzed using a small RNA library, and a total of 563 miRNAs that significantly changed (p < 0.05) across gestation and 101 miRNAs were significantly changed between NGT and GDM. Analysis of the miRNA changes in NGT and GDM separately identified a total of 256 (NGT-group), and 302 (GDM-group) miRNAs that change across gestation. A multivariate classification model was developed, based on the quantitative expression of EV-associated miRNAs, and the accuracy to correctly assign samples was > 90%. We identified a set of proteins in skeletal muscle biopsies from women with GDM associated with JAK-STAT signaling which could be targeted by the miRNA-92a-3p within circulating EVs. Interestingly, overexpression of miRNA-92a-3p in primary skeletal muscle cells increase insulin-stimulated glucose uptake. CONCLUSIONS: During early pregnancy, differently-expressed, EV-associated miRNAs may be of clinical utility in identifying presymptomatic women who will subsequently develop GDM later in gestation. We suggest that miRNA-92a-3p within EVs might be a protected mechanism to increase skeletal muscle insulin sensitivity in GDM.

OBJECTIVES: We aimed to establish new cut-off values for SIRS (Systemic Inflammatory Response Syndrome) variables in the obstetric population. METHODS: A prospective cohort study in pregnant and postpartum women admitted with systemic infections between December 2017 and January 2019. Patients were divided into three cohorts: Group A, patients with infection but without severe maternal outcomes (SMO); Group B, patients with infection and SMO or admission to the intensive care unit (ICU); and Group C, a control group. Outcome measures were ICU admission and SMO. The relationship between SIRS criteria and SMO was expressed as the area under the receiver operating characteristics curve (AUROC), selecting the best cut-off for each SIRS criterion. RESULTS: A total of 541 obstetric patients were enrolled, including 341 with infections and 200 enrolled as the reference group (Group C). The patients with infections included 313 (91.7%) in Group A and 28 (8.2%) in Group B. There were significant differences for all SIRS variables in Group B, compared with Groups A and C, but there were no significant differences between Groups A and C. The best cut-off values were the following: temperature 38.2 °C, OR 4.1 (1.8-9.0); heart rate 120 bpm, OR 2.9 (1.2-7.4); respiratory rate 22 bpm, OR 4.1 (1.6-10.1); and leukocyte count 16,100 per mcl, OR 3.5 (1.6-7.6). CONCLUSIONS: The cut-off values for SIRS variables did not differ between healthy and infected obstetric patients. However, a higher cut-off may help predict the population with a higher risk of severe maternal outcomes.

Preeclampsia (PE) and fetal growth restriction (FGR) are both placenta-mediated disorders with unclear pathogenesis. Metabolomics of maternal and fetal pairs might help in understanding these disorders. We recruited prospectively pregnancies with normotensive FGR, PE without FGR, PE + FGR and uncomplicated pregnancies as controls. Nuclear magnetic resonance metabolomics were applied on plasma samples collected at delivery. Advanced lipoprotein, glycoprotein and choline profiling was performed using the Liposcale test. The software package Dolphin was used to quantify 24 low-molecular-weight metabolites. Statistical analysis comprised the comparison between each group of complicated pregnancies versus controls, considering 5% false discovery rate correction. Lipid profiles were altered in accordance with the clinical presentation of these disorders. Specifically, PE mothers and FGR fetuses (with or without FGR or PE, respectively) exhibited a pro-atherogenic and pro-inflammatory profile, with higher concentrations of triglycerides, remnant cholesterol (VLDL, IDL) and Glc/GalNAc-linked and lipid-associated glycoproteins compared to controls. Low-molecular-weight metabolites were extensively disturbed in preeclamptic mothers, with or without FGR. Growth restricted fetuses in the presence of PE showed changes in low-molecular-weight metabolites similar to their mothers (increased creatine and creatinine), while normotensive FGR fetuses presented scarce differences, consistent with undernutrition (lower isoleucine). Further research is warranted to clarify maternal and fetal adaptations to PE and FGR.

Fetal growth restriction is one of the most common obstetric complications, affecting 7-10% of all pregnancies. Affected fetuses are exposed to an adverse environment in utero during a critical time of development and may face long-term health consequences such as increased cardiovascular risk in adulthood. Growth restricted fetuses develop remodeled hearts with signs of systolic and diastolic dysfunction. Cardiac adaptations are more evident in early severe cases, but also present in late onset fetal growth restriction. Cardiovascular remodeling persists into postnatal life, from the neonatal period to adolescence, encompassing an increased susceptibility to adult disease. In this review, we summarize the current evidence on cardiovascular programming associated to fetal growth restriction, its postnatal consequences and potential strategies to reduce their cardiovascular risk.

Preeclampsia is a pregnancy-specific multisystem disorder and a leading cause of maternal and perinatal morbidity and mortality. The exact pathogenesis of this multifactorial disease remains poorly defined. We applied proteomics analysis on maternal blood samples collected from 14 singleton pregnancies with early-onset severe preeclampsia and 6 uncomplicated pregnancies to investigate the pathophysiological pathways involved in this specific subgroup of preeclampsia. Maternal blood was drawn at diagnosis for cases and at matched gestational age for controls. LC-MS/MS proteomics analysis was conducted, and data were analyzed by multivariate and univariate statistical approaches with the identification of differential pathways by exploring the global human protein-protein interaction network. The unsupervised multivariate analysis (the principal component analysis) showed a clear difference between preeclamptic and uncomplicated pregnancies. The supervised multivariate analysis using orthogonal partial least square discriminant analysis resulted in a model with goodness of fit (R2X = 0.99, p < 0.001) and a strong predictive ability (Q2Y = 0.8, p < 0.001). By univariate analysis, we found 17 proteins statistically different after 5% FDR correction (q-value < 0.05). Pathway enrichment analysis revealed 5 significantly enriched pathways whereby the activation of the complement and coagulation cascades was on top (p = 3.17e-07). To validate these results, we assessed the deposits of C5b-9 complement complex and on endothelial cells that were exposed to activated plasma from an independent set of 4 cases of early-onset severe preeclampsia and 4 uncomplicated pregnancies. C5b-9 and Von Willbrand factor deposits were significantly higher in early-onset severe preeclampsia. Future studies are warranted to investigate potential therapeutic targets for early-onset severe preeclampsia within the complement and coagulation pathway.

Resumen ANTECEDENTES: Las enfermedades respiratorias graves suelen afectar de manera desproporcionada a las mujeres embarazadas y representan un mayor riesgo de morbilidad y mortalidad materna y neonatal severas. Los informes clínicos de los desenlaces maternos y neonatales en mujeres embarazadas con COVID-19 siguen siendo escasos a pesar de la cantidad de información que surge a diario en la bibliografía universal. OBJETIVOS: Describir los desenlaces maternos y perinatales de las pacientes embarazadas con diagnóstico positivo de infección respiratoria aguda en la ciudad de Cartagena en el periodo de marzo a diciembre de 2020. MÉTODOS: Estudio observacional, descriptivo y transversal efectuado en mujeres embarazadas con diagnóstico positivo de infección por COVID-19. RESULTADOS: De las 120 participantes se excluyeron 70 por no tener diagnóstico confirmado por PCR para SARS-CoV-2. Se analizaron 50 pacientes con una mediana de edad de 29 años (RIC 24-32). El 30% requirió hospitalización, el 96% de las pacientes tuvo síntomas; el más frecuente fue la tos con un 50%, seguido de fiebre y anosmia con 42%. Las complicaciones maternas se registraron en el 28% de los casos, 14% requirieron atención en la UCI, además, el 6% de la muestra falleció. El 12% ameritó reanimación neonatal y el 24% se internó en la UCI. CONCLUSIONES: La mayoría tuvo síntomas respiratorios durante el ingreso, con una alta tasa de mortalidad materna. No se registraron desenlaces fatales en los neonatos.
Abstract BACKGROUND: Severe respiratory diseases tend to disproportionately affect pregnant women, representing an increased risk of severe maternal and neonatal morbidity and mortality. Clinical reports on maternal and neonatal outcomes in pregnant women with COVID-19 remain scarce despite the amount of information that emerges daily in the universal literature. OBJECTIVE: Describe the maternal and perinatal outcomes of pregnant patients with a positive diagnosis for acute respiratory infection COVID-19 in the city of Cartagena in the period between March and December 2020. METHODS: This was an observational, descriptive cross-sectional study was conducted including pregnant women with a positive diagnosis of COVID-19 infection in the city of Cartagena, between March 2020 and December 2020. RESULTS: Of the 120 participants, 70 were excluded for not having a diagnosis confirmed by PCR for SARS-CoV-2, 50 patients with a median age of 29 years (IQR 24 - 32) were analyzed, 30% required hospitalization, 96% of the patients presented symptoms, the most frequently referred being cough with 50%, followed by fever and anosmia with 42%. Maternal complications occurred in 28% of the cases, requiring admission to the ICU in 14%, and death occurred in 6% of the sample. 12% required neonatal resuscitation and 24% were admitted to the ICU. CONCLUSIONS: Most had respiratory symptoms during admission, with a high maternal mortality rate. There were no neonatal fatal outcomes.
RESUMEN
Fetal growth restriction defined as the failure to achieve the fetal genetic growth potential is a major cause of perinatal morbidity and mortality. The role of maternal adaptations to placental insufficiency in this disorder is still not fully understood. We aimed to investigate the biological processes and protein-protein interactions involved in late-onset fetal growth restriction in particular. We applied 2D nano LC-MS/MS proteomics analysis on maternal blood samples collected at the time of delivery from 5 singleton pregnancies with late-onset fetal growth restriction and 5 uncomplicated pregnancies. Data were analyzed using R package "limma" and Ingenuity Pathway Analysis. 25 proteins showed significant changes in their relative abundance in late-onset fetal growth restriction (p value < 0.05). Direct protein-protein interactions network demonstrated that Neurogenic locus notch homolog protein 1 (NOTCH1) was the most significant putative upstream regulator of the observed profile. Gene ontology analysis of these proteins revealed the involvement of 14 canonical pathways. The most significant biological processes were efflux of cholesterol, efflux of phospholipids, adhesion of blood cells, fatty acid metabolism and dyslipidemia. Future studies are warranted to validate the potential role of the detected altered proteins as potential therapeutic targets in the late-onset form of fetal growth restriction.

Hemopexin and α1-microglobulin act as scavengers to eliminate free heme-groups responsible for hemoglobin-induced oxidative stress. The present study evaluated maternal and fetal plasma concentrations of these scavengers in the different phenotypes of placenta-mediated disorders. Singleton pregnancies with normotensive fetal growth restriction [FGR] (n = 47), preeclampsia without FGR (n = 45) and preeclampsia with FGR (n = 51) were included prospectively as well as uncomplicated pregnancies (n = 49). Samples were collected at delivery and ELISA analysis was applied to measure the hemopexin and α1-microglobulin concentrations. In maternal blood in preeclampsia with and without FGR, hemopexin was significantly lower (p = 0.003 and p<0.001, respectively) and α1-microglobulin was significantly higher (p<0.001 in both) whereas no difference existed in normotensive FGR mothers compared to controls. In contrast, in fetal blood in growth restricted fetuses with and without preeclampsia, both hemopexin and α1-microglobulin were significantly lower (p<0.001 and p = 0.001 for hemopexin, p = 0.016 and p = 0.013 for α1-microglobulin, respectively) with no difference in fetuses from preeclampsia without FGR in comparison to controls. Thus, hemopexin and α1-microglobulin present significantly altered concentrations in maternal blood in the maternal disease -preeclampsia- and in cord blood in the fetal disease -FGR-, which supports their differential role in placenta-mediated disorders in accordance with the clinical presentation of these disorders.

OBJECTIVE: To assess clinical impact, psychological effects, and knowledge of pregnant women during the COVID-19 outbreak in seven cities in Colombia. Currently, there are uncertainty and concerns about the maternal and fetal consequences of SARS-CoV-2 infection during pregnancy. METHODS: A cross-sectional web survey was carried out including pregnant women in seven cities in Colombia. Women were evaluated during the mitigation phase of the SARS-CoV-2 pandemic between April 13 and May 18, 2020. The questions evaluated demographic, knowledge, psychological symptoms, and attitudes data regarding the COVID-19 pandemic. RESULTS: A total of 1021 patients were invited to participate, obtaining 946 valid surveys for analysis. The rate of psychological consequences of the pandemic was much larger than the number of patients clinically affected by the virus, with 50.4% of the entire cohort reporting symptoms of anxiety, 49.1% insomnia, and 25% reporting depressive symptoms. Poorly informed women were more likely to be younger, affiliated to the subsidized regime, and with lower levels of education. CONCLUSION: The knowledge of pregnant women about SARS-CoV-2 infection is far from reality and this seems to be associated with an indirect effect on the concern and psychological stress of pregnant women in Colombia.
