RESUMO

PROBLEM: Families living in rural communities need to relocate, be transferred or travel long distances to access specialist maternal and neonatal care, leading to isolation from their support networks. BACKGROUND: High-risk maternal and neonatal complexities in rural maternity units results in more transfers and retrievals to metropolitan services. There is limited understanding of the physical and psychological impacts for women and their families when they are transferred or displaced from their rural communities during pregnancy. AIM: To investigate the lived experience of relocation for specialist pregnancy, birthing, postnatal and neonatal care on women and families. METHODS: Women (n=5) and partners (n=4) from rural South Australia, participated in semi-structured interviews on their experiences of transfer from local maternity providers. Couples interviewed together, interactions were recorded, transcribed verbatim and thematically analysed to identify overarching and sub-themes. FINDINGS: The overarching theme was 'mismatched expectations', with three identified sub-themes: 'communication', 'compassion' and 'safety'. Discrepancies between expectations and realities during relocation left participants feeling isolated, alone and needing to self-advocate during this vulnerable period. Despite receiving specialist care, women and partners encountered unique hardships when separated from their rural community. Their social needs were poorly understood and seldom addressed in specialist units, resulting in poor experiences. DISCUSSION: Consideration regarding the impact of attending specialist maternity services for women and partners from rural areas is required. The 'one size fits all' approach for maternity care is unrealistic and research is needed to improve the experiences for those uprooted from rural communities for higher levels of care.

RESUMO

BACKGROUND: The worldwide incidence of preterm births is increasing, and the risks of adverse outcomes for preterm infants significantly increase with shorter gestation, resulting in a substantial socioeconomic burden. Limited epidemiological studies have been conducted in China regarding the incidence and spatiotemporal trends of preterm births. Seasonal variations in risk indicate the presence of possible modifiable factors. Gender influences the risk of preterm birth. OBJECTIVE: This study aims to assess the incidence rates of preterm birth, very preterm birth, and extremely preterm birth; elucidate their spatiotemporal distribution; and investigate the risk factors associated with preterm birth. METHODS: We obtained data from the Guangdong Provincial Maternal and Child Health Information System, spanning from January 1, 2014, to December 31, 2021, pertaining to neonates with gestational ages ranging from 24 weeks to 42 weeks. The primary outcome measures assessed variations in the rates of different preterm birth subtypes over the course of the study, such as by year, region, and season. Furthermore, we examined the relationship between preterm birth incidence and per capita gross domestic product (GDP), simultaneously analyzing the contributing risk factors. RESULTS: The analysis incorporated data from 13,256,743 live births. We identified 754,268 preterm infants and 12,502,475 full-term infants. The incidences of preterm birth, very preterm birth, and extremely preterm birth were 5.69 per 100 births, 4.46 per 1000 births, and 4.83 per 10,000 births, respectively. The overall incidence of preterm birth increased from 5.12% in 2014 to 6.38% in 2021. The incidence of extremely preterm birth increased from 4.10 per 10,000 births in 2014 to 8.09 per 10,000 births in 2021. There was a positive correlation between the incidence of preterm infants and GDP per capita. In more developed economic regions, the incidence of preterm births was higher. Furthermore, adjusted odds ratios revealed that advanced maternal age, multiple pregnancies, and male infants were associated with an increased risk of preterm birth, whereas childbirth in the autumn season was associated with a protective effect against preterm birth. CONCLUSIONS: The incidence of preterm birth in southern China exhibited an upward trend, closely linked to enhancements in the care capabilities for high-risk pregnant women and critically ill newborns. With the recent relaxation of China's 3-child policy, coupled with a temporary surge in advanced maternal age and multiple pregnancies, the risk of preterm birth has risen. Consequently, there is a pressing need to augment public health investments aimed at mitigating the risk factors associated with preterm birth, thereby alleviating the socioeconomic burden it imposes.

RESUMO

OBJECTIVE: A supportive environment for women with Hyperemesis Gravidarum is crucial but not always provided. There is a lack of research regarding Hyperemesis Gravidarum, its impact on the family, and the partner's perception of supporting their spouse. Thus, this study aims to explore partners' experiences of Hyperemesis Gravidarum during their spousés pregnancy. METHODS: Data were gathered through 13 individual, semi-structured, in-depth, digital interviews with partners of women who had experienced Hyperemesis Gravidarum and analysed with Qualitative Content Analysis. The partners were recruited through advertisement on a social media platform and were exclusively males, representing 8 of 21 Swedish regions. The mean age was 34, and they had, on average, 1 previous child. The mean time from the experience to the interview was 12 months. FINDINGS: The main theme, "Navigating in a maze without a map", explains partners' situation as stressful and demanding when their spouse suffers from Hyperemesis Gravidarum, with insufficient support and guidance from healthcare providers. The analysis resulted in three themes: "Standing alone with a demanding responsibility", "Being in a lottery when facing healthcare", and "Climbing the mountain together." The themes display challenges within everyday life and healthcare, as well as strained relations within the family. CONCLUSION: Partners experience a need to support their spouse in every aspect of daily life and advocate for adequate healthcare. Healthcare professionals must support and acknowledge the partners' struggles during the demanding situation with Hyperemesis Gravidarum.

RESUMO

Background: The Gambia has the 12th highest maternal mortality rate in the world, with 80% of deaths resulting from avoidable causes. Unawareness of pregnancy danger signs (DS) has been shown to be a barrier to seeking obstetric care, while app-based education intervention has shown promise. Objective: We aim to assess patient awareness of DS, identify barriers to awareness, and evaluate potential for implementing smartphone-based technologies for education. Methods: A cross-sectional semi-structured survey was administered to Gambian women (n = 100) across five hospitals/health centers. Data and informed consent were collected via an online survey portal. Analysis included bivariate analysis and descriptive statistics with p < 0.05 significance level. Recall of 0-2 DS per category was classified as "low" knowledge, 3-5 as "moderate" knowledge, and 6+ as "sufficient" knowledge. Cross-category recall was quantified for overall awareness level (0-6 = "low", 7-12 = "moderate", 13+ = "sufficient". N = 28 total DS). Findings: Although 75% of participants (n = 100) self-perceived "sufficient" knowledge of DS, the average recall was only two (SD = 2, n = 11) pregnancy DS, one labor and delivery DS (SD = 1, n = 8), and one postpartum DS (SD = 1, n = 9). Twenty-one women were unable to recall any danger signs. "Low" awareness was identified in 77% of women, while 23%, and 0% of women showed "moderate" and "sufficient" overall awareness, respectively. Education level was significantly correlated with overall danger sign recall (ρ(98) = .243, p = .015) and awareness level (ρ(98) = .265, p = .008). Monthly income was significantly correlated with awareness level (ρ(97) = .311, p = .002). Smartphone ownership was reported by 76% of women, and 97% expressed interest in using app-based video (94%) or provider (93%) teaching. Conclusions: Women had low knowledge of obstetric danger signs, and true awareness of danger signs was remarkably lower than self-perceived knowledge. However, patients exhibited proper healthcare-seeking behavior when danger signs arose. Findings suggest that video- or messaging-based education from local healthcare providers may be effective DS educational interventions.

RESUMO

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

RESUMO

INTRODUCTION: Effect of physical activity in pregnancy on preeclampsia (PE) and angiogenic markers is not well understood. We studied the association of physical activity and PE in a case-control setting and assessed whether exercise in PE and non-PE women associate with maternal serum concentrations of soluble fms-like tyrosine kinase 1 (s-Flt-1), placental growth factor (PlGF) and soluble endoglin (sEng) and sFlt-1/PlGF ratio in the Finnish Genetics of Pre-eclampsia Consortium (FINNPEC) cohort. MATERIALS AND METHODS: Participants completed a questionnaire on their background information and serum samples were collected from a subset. Questionnaire data on physical activity were available from 708 PE women and 724 non-PE women. Both first trimester serum samples and questionnaire data on physical activity were available from 160 PE women and 160 non-PE women, and second/third trimester serum samples and questionnaire data on physical activity were available from 139 PE women and 47 non-PE women. The PE and non-PE women were divided into categories of physically active (exercise 2 - 3 times/week or more) and physically inactive (exercise less than 2 - 3 times/week). RESULTS: A total of 43.4% of the PE women and 42.4% of the non-PE women were categorized as physically active. There were no differences in physical activity and exercise habits between the groups. The physically active women were more often nulliparous and non-smokers and had a lower body mass index. There were no differences in the concentrations of angiogenic markers (sFlt-1, PlGF and sEng and sFlt-1/PlGF ratio) between the groups who exercised more or less than 2 - 3 times/week. CONCLUSIONS: In the FINNPEC study cohort, there was no association between physical activity and PE and no associations of physical activity in pregnant women with and without PE with maternal serum concentrations of sFlt-1, PlGF and sEng and sFlt-1/PlGF ratio.


This is the first study to investigate the association of physical activity in pregnancy with concentrations of angiogenic markers while comparing pregnant women with and without preeclampsia.There were no differences in the physical activity and exercise habits in pregnancy between women with and without preeclampsia in the FINNPEC cohort.Physical activity of pregnant women with or without preeclampsia did not associate with the concentrations of angiogenic markers (sFlt-1, PlGF and sEng and sFlt-1/PlGF ratio).

RESUMO

AIM: To analyse key pregnancy and birth outcomes for First Nations women and children at a Western Sydney metropolitan tertiary referral centre. METHODS: The birth and health-determining characteristics of 470 First Nations infants born at Nepean Hospital in 2018 and their mothers were included in a retrospective audit and compared with a contemporaneous control group of 470 infants and their mothers. RESULTS: Mothers of First Nations infants had significantly higher rates of socioeconomic disadvantage (P < 0.001), psychosocial vulnerability (P < 0.007), mental illness (P < 0.001), teenage pregnancy (P < 0.001), smoking (45.6% vs. 19.4%, P < 0.001) and drug and alcohol use than control mothers (P < 0.001, P < 0.048). First Nations peoples did not have increased rates of maternal morbidity, nor any difference in rates of Caesarean section, resuscitation at birth, NICU admission, preterm birth or low birth weight in multivariable analysis. However, multivariable analysis demonstrated significant associations between low birth weight and maternal smoking (P < 0.001), hypertension (P < 0.01) and drug use (P < 0.01). CONCLUSIONS: Despite challenges facing First Nations mothers and infants, our study found no significant difference in maternal morbidity nor adverse birth outcomes for First Nations infants. The study occurred in the context of culturally specific, First Nations-led antenatal and infant services. Future studies should further investigate relationships between participation in these services and health outcomes. This could identify strengths and areas for improvement in current services, with the goal of further improving outcomes for First Nations peoples through targeted health services that address their psychosocial vulnerabilities and support women to make healthy choices during pregnancy.

RESUMO

INTRODUCTION: Preeclampsia (PE) is a severe pregnancy complication due to placental dysfunction. Thrombomodulin (TM), a glycoprotein expressed on the trophoblast cell membrane, plays an organ-protective role in the placenta by regulating coagulation and inflammation. TM-mediated regulation of High Mobility Group Box1(HMGB1) is an essential mechanism that contributes to placental homeostasis and prevents pregnancy complications in mice. Here, we aimed to clarify the role of placental TM and HMGB1 in the pathophysiology of human PE. METHODS AND RESULTS: In this study, maternal blood serum and placental tissue were obtained from 72 PE patients and 110 normal controls. Soluble TM(sTM) and HMGB1 levels in the maternal serum were assessed. The placental TM and HMGB1 expression levels were evaluated using immunohistochemistry and qPCR. Serum sTM and HMGB1 levels gradually increased with gestational age in normal pregnancies; however, both circulating sTM and HMGB1 levels were significantly higher in the PE group. Serum HMGB1/sTM ratio was elevated in PE patients compared to that in normal controls, which correlated positively with the clinical severity of PE. The immunohistochemistry analysis revealed the loss of TM and the increase in extranuclear HMGB1. TM mRNA expression was diminished in PE placentas, which negatively correlated with soluble fms-like tyrosine kinase-1 (sFlt-1) expression. DISCUSSION: The increase in circulating sTM and HMGB1 could be attributed to the enhanced placental TM shedding in PE patients. The molecular events mediated by the imbalance in the placental TM and HMGB1 levels could be an underlying feature of PE; maternal serum HMGB1/sTM ratio could reflect this status.

RESUMO

AIM: To estimate the incidence of abruption in first births and recurrence in the subsequent birth in patients of a large US-based integrated health care system. METHODS: Retrospective population-based cohort study of patients with first two consecutive singleton births using data from the Kaiser-Permanente South California health care system who delivered over a period of 30 years (1991-2021), using longitudinally linked electronic health records. ICD-9/ICD-10 codes "641.20" and "O45.x" identified placental abruption. We calculated the incidence and rates of abruption in first and second pregnancies. We used logistic regression to estimate the adjusted odds ratios (aOR) for abruption in second pregnancies in patients with and without abruptions in their first pregnancies. RESULTS: Of the 126 264 patients with first two consecutive singleton births over the period, 805 had abruptions in their first births, and 861 in their second births. Rates of abruption in first and second births were 0.63% and 0.68%, respectively. Twenty-seven patients had abruptions in both first and second births. Rates of abruption in the second birth among individuals with and without previous placental abruption were 3.35% and 0.66%, respectively, giving an approximately five-fold increased odds of abruption in a second pregnancy in individuals who had abruption in their first birth when compared with those who did not have placental abruption in their first birth (aOR: 4.95, 95% confidence interval: 3.35-7.31, p < 0.00001). Interpregnancy interval had no statistically significant association with recurrence. CONCLUSION: Abruption in a first birth is associated with an approximately five-fold increased odds of abruption in a second birth.

RESUMO

The COVID-19 pandemic has had a significant and enduring influence on global health, including maternal and fetal well-being. Evidence suggests that placental dysfunction is a potential consequence of SARS-CoV-2 infection during pregnancy, which may result in adverse outcomes such as preeclampsia and preterm birth. However, the molecular mechanisms underlying this association remain unclear, and it is uncertain whether a mature placenta can protect the fetus from SARS-CoV-2 infection. To address the above gap, we conducted a transcriptome-based study of the placenta in both maternal and fetal compartments. We collected placental samples from 16 women immediately after term delivery, seven of which had SARS-CoV-2 infection confirmed by PCR before parturition. Notably, we did not detect any viral load in either the maternal or fetal compartments of the placenta, regardless of symptomatic status. We separately extracted total RNA from placental tissues from maternal and fetal compartments, constructed cDNA libraries, and sequenced them to assess mRNA. Our analysis revealed 635 differentially expressed genes when a false discovery rate (FDR ≤ 0.05) was applied in the maternal placental tissue, with 518 upregulated and 117 downregulated genes in the SARS-CoV-2-positive women (n = 6) compared with the healthy SARS-CoV-2-negative women (n = 8). In contrast, the fetal compartment did not exhibit any significant changes in gene expression with SARS-CoV-2 infection. We observed a significant downregulation of nine genes belonging to the pregnancy-specific glycoprotein related to the immunoglobulin superfamily in the maternal compartment with active SARS-CoV-2 infection (fold change range from -13.70 to -5.28; FDR ≤ 0.01). Additionally, comparing symptomatic women with healthy women, we identified 1788 DEGs. Furthermore, a signaling pathway enrichment analysis revealed that pathways related to oxidative phosphorylation, insulin secretion, cortisol synthesis, estrogen signaling, oxytocin signaling, antigen processing, and presentation were altered significantly in symptomatic women. Overall, our study sheds light on the molecular mechanisms underlying the reported clinical risks of preeclampsia and preterm delivery in women with SARS-CoV-2 infection. Nonetheless, studies with larger sample sizes are warranted to further deepen our understanding of the molecular mechanisms of the placenta's anti-viral effects in maternal SARS-CoV-2 infection.

RESUMO

Cardiovascular disease (CVD) is a leading cause of mortality and disease burden in women globally. A healthy diet is important for the prevention of CVD. Research has consistently favoured the Mediterranean diet as a cardio-protective diet. Several studies have evaluated associations between the Mediterranean diet and cardiovascular outcomes, including traditional risk factors like hypertension, type 2 diabetes mellitus, and obesity. In addition, consistent evidence suggests that the components of the Mediterranean diet have a synergistic effect on cardiovascular risk due to its anti-inflammatory profile and microbiome effects. While the benefits of the Mediterranean diet are well-established, health advice and dietary guidelines have been built on largely male-dominant studies. Few studies have investigated the beneficial associations of the Mediterranean diet in sex-specific populations, including those with non-traditional risk factors that are specific to women, for instance polycystic ovarian syndrome and high-risk pregnancies, or more prevalent in women, such as chronic inflammatory diseases. Therefore, this review aims to provide a comprehensive overview of the current evidence regarding the Mediterranean diet in women in relation to cardiovascular health outcomes.

RESUMO

OBJECTIVE: Docosahexaenoic acid (DHA) is recommended routinely in pregnancy to promote fetal development. DHA has anti-inflammatory activity, but its effects on the fetal heart and circulation are unknown. This study aimed to investigate whether maternal DHA supplementation in the third trimester affects maternal prostaglandin levels and fetal ductus arteriosus flow dynamics. METHODS: This was a double-blind randomized controlled trial with parallel groups conducted between 2018 and 2021. Pregnant women aged over 18 years with a normal fetus at 27-28 weeks' gestation showing no cardiac/extracardiac anomalies or ductal constriction were eligible for the trial. Women consuming substances with a known inhibitory effect on prostaglandin metabolism, such as non-steroidal anti-inflammatory drugs and polyphenol-rich foods, were excluded. The intervention group received oral supplementation of omega-3 with 450 mg/day of DHA for 8 weeks and the placebo group received capsules of soy lecithin for 8 weeks. Anthropometric measurements, assessment of polyphenol and omega-3 consumption, fetal morphological ultrasound examination, fetal Doppler echocardiographic examination and blood sample collection were performed at the start of the study and the latter two were repeated at follow-up. Prostaglandin E2 (PGE2) level and echocardiographic parameters were compared between the intervention and placebo groups and between baseline and follow-up. RESULTS: A total of 24 participants were included in each group. After 8 weeks, there were no significant differences between the intervention and placebo groups in maternal serum PGE2 level or Doppler echocardiographic parameters of ductal flow. No case of ductus arteriosus constriction was observed. The expected intragroup changes in cardiac morphology, as a result of advancing gestation, were present. CONCLUSIONS: Maternal DHA supplementation in the third trimester at a clinically recommended dose did not result in inhibition of PGE2 or constriction of the ductus arteriosus. These findings should be confirmed in postmarket surveillance studies with larger patient numbers in order to test the full safety profile of DHA and provide robust clinical reassurance. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

RESUMO

BACKGROUND: Polycystic ovarian syndrome (PCOS) is recognized as the most prevalent endocrine disorder among women of reproductive age. While the utilization of assisted reproductive technology (ART) has resulted in favorable outcomes for infertility treatment in PCOS patients, the inherent pathophysiological features of the condition give rise to complications and consequences during pregnancy and delivery for both the mother and offspring. This study was to assess the correlation between maternal PCOS and various pregnancy complications and neonatal outcomes undergone ART. METHODS: A systematic search was conducted on PubMed, EmBase, and the Cochrane Library to identify observational studies that investigated the association between PCOS and the risk of various pregnancy complications and neonatal outcomes, including gestational diabetes mellitus (GDM), hypertension in pregnancy (PIH), preeclampsia (PE), preterm birth, abortion, congenital malformations (CA), small for gestational age (SGA), large for gestational age (LGA), low birth weight (LBW), macrosomia, neonatal intensive care unit (NICU) admission and birth weight. Eligible studies were selected based on predetermined inclusion and exclusion criteria. The meta-analysis was conducted using Review Manager and Stata software, with odds ratios (ORs) or mean difference (MD), confidence intervals (CIs), and heterogeneity (I2) being calculated. The search was conducted up to March 2023. RESULTS: A total of 33 studies with a combined sample size of 92,810 participants were identified. The findings indicate that PCOS is significantly associated with an increased risk of GDM (OR 1.51, 95% CI:1.17-1.94), PIH (OR 1.72, 95% CI:1.25-2.39), PE (OR 2.12, 95% CI:1.49-3.02), preterm birth (OR 1.29, 95% CI:1.21-1.39), and LBW (OR 1.29, 95% CI:1.14-1.47). In subgroup analyses, the risks of GDM (OR 1.80, 95% CI:1.23-2.62) and abortion (OR 1.41, 95% CI:1.08-1.84) were elevated in fresh embryo transferred (ET) subgroup, whereas elevated risk of PE (OR 1.82, 95% CI:1.17-2.83) and preterm birth (OR 1.31, 95% CI:1.21-1.42) was identified in frozen ET subgroup. Whatever with or without hyperandrogenism, patients with PCOS had a higher risk in preterm birth (OR 1.69, 95% CI: 1.31-2.18; OR 1.24, 95% CI:1.02-1.50) and abortion (OR 1.38, 95% CI:1.12-1.71; OR 1.23, 95% CI:1.06-1.43). CONCLUSION: Our findings suggest that individuals with PCOS undergone ART are at a notably elevated risk for experiencing pregnancy complications and unfavorable neonatal outcomes. Nevertheless, to establish a definitive association between PCOS and pregnancy-related outcomes, it is necessary to conduct extensive prospective, blinded cohort studies and effectively control for confounding variables.

BACKGROUND AND OBJECTIVES: Maternal obesity influences pregnancy course in several different manners, and imbalanced nutrition during pregnancy may lead to various adverse pregnancy outcomes. Additionally, nutritional status during pregnancy may have implications for the health of the offspring and may possibly influence early motor development in children. The aim of this study was to assess the impact of excessive gestational weight gain (EGWG) on pregnancy outcomes and infant's motor development within the first twelve months of life. MATERIALS AND METHODS: The study included 200 participants divided in two groups based on their gestational weight gain. Maternal, perinatal, and neonatal factors were analyzed, and early motor development was assessed using the Alberta infant motor scale (AIMS). RESULTS: EGWG was significantly associated with: pre-pregnancy BMI (p < 0.001), family history for cardiovascular diseases (p = 0.013) and diabetes mellitus (p = 0.045), hypertensive disorder of pregnancy (p = 0.003), gestational diabetes mellitus (p < 0.001), gestational anemia (p = 0.001), vitamin D deficiency (p = 0.001), metformin use (p = 0.045), pre-labor premature rupture of membranes (p = 0.031), amniotic fluid index (p = 0.047), and APGAR score in the first five min of life (p = 0.007). Scored by AIMS, EGWG was significantly associated with parameters of early motor development at the age of three AIMS total (p < 0.001), six AIMS total (p < 0.001), nine AIMS total (p < 0.001), and twelve AIMS total (p < 0.001) months of infant's life. CONCLUSIONS: The link between EGWG and adverse neurodevelopmental outcomes in offspring is a complex and multifaceted issue. Our results imply significant alterations in early motor development in the group of infants born from mothers who gained weight excessively during pregnancy. Further studies are needed to unravel the intricacies of this relationship and inform strategies for preventive interventions and supportive care during pregnancy and infancy.

RESUMO

BACKGROUND: The establishment of maternal-fetal crosstalk is vital to a successful pregnancy. Glycosylation is a post-translational modification in which glycans (monosaccharide chains) are attached to an organic molecule. Glycans are involved in many physiological and pathological processes. Human endometrial epithelium, endometrial gland secretions, decidual immune cells, and trophoblasts are highly enriched with glycoconjugates and glycan-binding molecules important for a healthy pregnancy. Aberrant glycosylation in the placenta and uterus has been linked to repeated implantation failure and various pregnancy complications, but there is no recent review summarizing the functional roles of glycosylation at the maternal-fetal interface and their associations with pathological processes. OBJECTIVE AND RATIONALE: This review aims to summarize recent findings on glycosylation, glycosyltransferases, and glycan-binding receptors at the maternal-fetal interface, and their involvement in regulating the biology and pathological conditions associated with endometrial receptivity, placentation and maternal-fetal immunotolerance. Current knowledge limitations and future insights into the study of glycobiology in reproduction are discussed. SEARCH METHODS: A comprehensive PubMed search was conducted using the following keywords: glycosylation, glycosyltransferases, glycan-binding proteins, endometrium, trophoblasts, maternal-fetal immunotolerance, siglec, selectin, galectin, repeated implantation failure, early pregnancy loss, recurrent pregnancy loss, preeclampsia, and fetal growth restriction. Relevant reports published between 1980 and 2023 and studies related to these reports were retrieved and reviewed. Only publications written in English were included. OUTCOMES: The application of ultrasensitive mass spectrometry tools and lectin-based glycan profiling has enabled characterization of glycans present at the maternal-fetal interface and in maternal serum. The endometrial luminal epithelium is covered with highly glycosylated mucin that regulates blastocyst adhesion during implantation. In the placenta, fucose and sialic acid residues are abundantly presented on the villous membrane and are essential for proper placentation and establishment of maternal-fetal immunotolerance. Glycan-binding receptors, including selectins, sialic-acid-binding immunoglobulin-like lectins (siglecs) and galectins, also modulate implantation, trophoblast functions and maternal-fetal immunotolerance. Aberrant glycosylation is associated with repeated implantation failure, early pregnancy loss and various pregnancy complications. The current limitation in the field is that most glycobiological research relies on association studies, with few studies revealing the specific functions of glycans. Technological advancements in analytic, synthetic and functional glycobiology have laid the groundwork for further exploration of glycans in reproductive biology under both physiological and pathological conditions. WIDER IMPLICATIONS: A deep understanding of the functions of glycan structures would provide insights into the molecular mechanisms underlying their involvement in the physiological and pathological regulation of early pregnancy. Glycans may also potentially serve as novel early predictive markers and therapeutic targets for repeated implantation failure, pregnancy loss, and other pregnancy complications.

RESUMO

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are associated with long-term maternal risks for cardiovascular disease for reasons that remain incompletely understood. METHODS: The HCHS/SOL (Hispanic Community Health Study/Study of Latinos), a multi-center community-based cohort of Hispanic/Latino adults recruited 2008 to 2011, was used to evaluate the associations of history of de novo HDP (gestational hypertension, preeclampsia, eclampsia) with echocardiographic measures of cardiac structure and function in Hispanic/Latina women with ≥1 prior pregnancy and the proportion of association mediated by current hypertension (>140/90 mm Hg or antihypertensive therapy). RESULTS.: The study cohort included 5168 Hispanic/Latina women with an average age (SD) of 58.7 (9.7) years at time of echocardiogram. Prior de novo HDP was reported by 724 (14%) of the women studied and was associated with lower left ventricle (LV) ejection fraction -0.66 (95% confidence interval [CI], -1.21 to -0.11), higher LV relative wall thickness 0.09 (95% CI, 0-0.18), and 1.39 (95% CI, 1.02-1.89) higher risk of abnormal LV geometry after adjusting for blood pressure and other confounders. The proportion of the association mediated by current hypertension between HDP and LV ejection fraction was 0.09 (95% CI, 0.03-0.45), LV relative wall thickness was 0.28 (95% CI, 0.16-0.51), abnormal LV geometry was 0.14 (95% CI, 0.12-0.48), concentric left ventricular hypertrophy was 0.31 (95% CI, 0.19-0.86), and abnormal LV diastolic dysfunction was 0.58 (95% CI, 0.26-0.79). CONCLUSIONS.: In a large cohort of Hispanic/Latina women those with history of de novo HDP had detectable and measurable subclinical alterations in cardiac structure and both systolic and diastolic dysfunction that were only partially mediated by current hypertension.

RESUMO

Obesity is recognized by the World Health Organization (WHO) as a disease in its own right. Moreover, obesity is an increasingly concerning public health issue across the world and its prevalence is rising amongst women of reproductive age. The fertility of over-weight and obese women is reduced and they experience a higher rate of miscarriage. In pregnant women obesity not only increases the risk of antenatal complications, such as preeclampsia and gestational diabetes, but also fetal abnormalities, and consequently the overall feto-maternal mortality. Ultrasound is one of the most valuable methods to predict and evaluate pregnancy complications. However, in overweight and obese pregnant women, the ultrasound examination is met with several challenges, mainly due to an impaired acoustic window. Overall obesity in pregnancy poses special challenges and constraints to the antenatal care and increases the rate of pregnancy complications, as well as complications later in life for the mother and child.

RESUMO

Obstetrical hemorrhage is a relatively frequent obstetrical complication and a common cause of maternal morbidity and mortality worldwide. The majority of maternal deaths attributable to hemorrhage are preventable, thus, developing rapid and effective means of treating postpartum hemorrhage is of critical public health importance. Intrauterine devices are one option for managing refractory hemorrhage, with rapid expansion of available devices in recent years. Intrauterine packing was historically used for this purpose, with historical cohorts documenting high rates of success. Modern packing materials, including chitosan-covered gauze, have recently been explored with success rates comparable to uterine balloon tamponade in small trials. There are a variety of balloon tamponade devices, both commercial and improvised, available for use. Efficacy of 85.9% was cited in a recent meta-analysis in resolution of hemorrhage with the use of uterine balloon devices, with greatest success in the setting of atony. However, recent randomized trials have demonstrated potential harm associated with improvised balloon tamponade use In low resource settings and the World Health Organization recommends use be restricted to settings where monitoring is available and care escalation is possible. Recently, intrauterine vacuum devices have been introduced, which offer a new mechanism for achieving hemorrhage control by mechanically restoring uterine tone via vacuum suction. The Jada device, which is is FDA-cleared and commercially available in the US, found successful bleeding control in 94% of cases in an initial single-arm trial, with recent post marketing registry study described treatment success following hemorrhage in 95.8% of vaginal and 88.2% of cesarean births. Successful use of improvised vacuum devices has been described in several studies, including suction tube uterine tamponade via Levin tubing, and use of a modified Bakri balloon. Further research is needed with head-to-head comparisons of efficacy of devices and assessment of cost within the context of both device pricing and overall healthcare resource utilization.

RESUMO

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae.


RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais.

RESUMO

Long non-coding RNAs are cellular transcripts that have ˃200 nucleotides in length and do not code for proteins. Due to their low expression levels, long non-coding RNAs were previously considered as mere transcriptional noise. However, current evidence indicates that they regulate a myriad of biological processes such as cell proliferation, invasion, and apoptosis. Hence, their expression patterns are crucial indicators of the physiological or pathological states of cells, tissues, and organs. The utilization of long non-coding RNAs as biomarkers and therapeutic targets for the clinical management of several diseases have been suggested. Gradually, long non-coding RNAs are gaining a substantial attention in the field of feto-maternal medicine. After embryo implantation, the interactions between the trophoblast cells from the embryo and the uterus of the mother facilitate placenta development and pregnancy progression. These processes are tightly regulated, and their impairments result in pregnancy pathologies such as miscarriage and preeclampsia. Accumulating evidence implicates long non-coding RNAs in these processes. Herein, we have summarized the roles of several long non-coding RNAs in human placenta development, have proposed some mechanisms by which they participate in physiological and pathological placentation, have revealed some knowledge deficits, and have recommended ideal experimental approaches that will facilitate the clarification of the mechanistic actions of each long non-coding RNA at the feto-maternal interface during healthy and pathological pregnancies.
