ABSTRACT

Hypertensive disorders of pregnancy (HDP) accounts for 18% of maternal deaths worldwide, with an estimated number of about 62, 000­77, 000 deaths occur each year. The current study aimed to assess maternal and perinatal outcomes of pregnancies complicated by hypertension in Aljala Maternity Hospital. A retrospective, descriptive, case series analysis for four hundred patients was done on the outcome of hypertensive disorder among pregnant women who admitted and were managed at Aljala teaching hospital with preeclampsia during the years 2019 and 2020. Demographic data involving age, parity, gestational week, clinical and laboratory findings were recorded from the medical files. Additionally, delivery route, indications of cesarean section, fetal and maternal complications were determined. The current finding reported high prevalence of perinatal and maternal mortality among pregnant women with preeclampsia. Moreover, other severe maternal and perinatal complications such as Hemolysis Elevated Liver Enzyme Platelet (HELLP) syndrome, placental abruption, eclamptic fits, as well as low birth weight were also commonly reported. The current study showed early onset of preeclampsia was associated with increased risk of developing adverse maternal-fetal/neonatal outcomes compared to lateonset after 36 weeks. Our findings call for special consideration and close surveillance of those women with early-onset diseases

ABSTRACT

BACKGROUND@#With an increasing proportion of multiparas, proper interpregnancy intervals (IPIs) are urgently needed. However, the association between IPIs and adverse perinatal outcomes has always been debated. This study aimed to explore the association between IPIs and adverse outcomes in different fertility policy periods and for different previous gestational ages.@*METHODS@#We used individual data from China's National Maternal Near Miss Surveillance System between 2014 and 2019. Multivariable Poisson models with restricted cubic splines were used. Each adverse outcome was analyzed separately in the overall model and stratified models. The stratified models included different categories of fertility policy periods (2014-2015, 2016-2017, and 2018-2019) and infant gestational age in previous pregnancy (<28 weeks, 28-36 weeks, and ≥37 weeks).@*RESULTS@#There were 781,731 pregnancies enrolled in this study. A short IPI (≤6 months) was associated with an increased risk of preterm birth (OR [95% CI]: 1.63 [1.55, 1.71] for vaginal delivery [VD] and 1.10 [1.03, 1.19] for cesarean section [CS]), low Apgar scores and small for gestational age (SGA), and a decreased risk of diabetes mellitus in pregnancy, preeclampsia or eclampsia, and gestational hypertension. A long IPI (≥60 months) was associated with an increased risk of preterm birth (OR [95% CI]: 1.18 [1.11, 1.26] for VD and 1.39 [1.32, 1.47] for CS), placenta previa, postpartum hemorrhage, diabetes mellitus in pregnancy, preeclampsia or eclampsia, and gestational hypertension. Fertility policy changes had little effect on the association of IPIs and adverse maternal and neonatal outcomes. The estimated risk of preterm birth, low Apgar scores, SGA, diabetes mellitus in pregnancy, and gestational hypertension was more profound among women with previous term births than among those with preterm births or pregnancy loss.@*CONCLUSION@#For pregnant women with shorter or longer IPIs, more targeted health care measures during pregnancy should be formulated according to infant gestational age in previous pregnancy.

Abstract Objective To analyze the effects of calcium supplementation on markers of preeclampsia over time by comparing the use of high- and low-dose calcium in hypertensive pregnant women. Methods This is a randomized clinical trial, placebo controlled, with three parallel groups carried out at the reference outpatient clinic for high-risk prenatal care in the South Region of Brazil, with intention-to-treat analysis and follow-up after four and eight weeks. The intervention consisted of ingesting calcium 500mg/day, calcium 1500mg/day and placebo. Data were analyzed according to a generalized mixed equation estimation model adopting α 0.05. Results The effect of low- and high-dose calcium on evolution over time was maintained between groups, even after adjustment for confounding factors. There was a significant difference in the parameters analyzed in the time and group interaction (p <0.000) and a decrease in the means of 12.3 mmHg in SBP, 9.2 mmHg in DBP, 3.2 mg/dl creatinine and 7.2 mg/dl proteinuria for the 500mg calcium/day group. The results were similar for the maximal supplementation group. Conclusion Calcium improved vascular prognosis in hypertensive pregnant women by reducing blood pressure levels and markers of preeclampsia. Brazilian Registry of Clinical Trials: RBR-9ngb95

ABSTRACT

Introducción: el embarazo causa adaptaciones en el riñón, tanto en anatomía como en función, para mantener el entorno extracelular, hemodinámico y hormonal. Sin embargo, estos pueden no llevarse a cabo de manera completamente óptima en presencia de enfermedad renal. El objetivo era estudiar la relación entre la enfermedad renal y los resultados maternos de fetal durante el embarazo, asociado con un rechazo por paciente y/o en relación con el tratamiento especializado. Material y métodos: estudio observacional y retrospectivo en una serie de casos, revisando 134 archivos de pacientes embarazadas con cierto grado de enfermedad renal antes del embarazo. Los resultados maternos registrados fueron: enfermedad hipertensiva durante el embarazo, deterioro renal agudo, necesidad de terapia de sustitución renal y en productos: prematuridad, restricción del crecimiento intrauterino, muerte fetal y aborto espontáneo. Resultados: Resultados maternos: tasa media de filtración glomerular (GFR) de 58.23 ml/min, aumento de peso de 7 kg; La preeclampsia fue diagnosticada en 92 mujeres (55 severas). 46 pacientes mostraron lesión renal aguda, 40 se resolvieron conservativamente; 1 requirió diálisis peritoneal y 15 hemodiálisis (con una decisión retrasada un promedio de un mes por rechazo por paciente y/o pariente). La resolución del embarazo fue por cesárea en 111 pacientes; Nacieron 116 productos antes de las 37 semanas de gestación, con un peso promedio de 1910 g, 94 mostraron restricción del crecimiento intrauterino. Conclusión: la enfermedad renal influyó directamente en el mayor número de resultados adversos maternos y fetales cuando se rechazó la atención médica especializada. Existe una correlación entre el ligero estado de Davison con los estados I, II y IIIA de Kdigo en el análisis de correspondencia


Introduction: Pregnancy causes adaptations in the kidney, both in anatomy and function, to maintain the extracellular, hemodynamic and hormonal environment. However, these may not be carried out completely optimally in the presence of kidney disease. The objective was to study the relation between kidney disease and maternal-fetal outcomes during pregnancy, associated with a rejection by patient and/or relative to specialized treatment. Material and Methods: Observational, retrospective study in a series of cases, reviewing 134 files of pregnant patients with some degree of kidney disease prior to pregnancy. Maternal outcomes recorded were: hypertensive disease during pregnancy, acute renal deterioration, need for renal substitution therapy, and in products: prematurity, restriction of intrauterine growth, fetal death and miscarriage. Results: Maternal outcomes: mean glomerular filtration rate (GFR) of 58.23ml/min, weight gain of 7 kg; preeclampsia was diagnosed in 92 women (55 severe). 46 patients showed acute renal lesion, 40 were conservatively resolved; 1 required peritoneal dialysis and 15 hemodialysis (with decision delayed an average of one month by rejection by patient and/or relative). Resolution of pregnancy was by cesarean in 111 patients; 116 products were born before 37 weeks of gestation, with average weight of 1910 g, 94 showed restriction of intrauterine growth. Conclusion: Kidney disease directly influenced the greater number of adverse maternal and fetal outcomes when specialized medical care was rejected. There is a correlation between slight Davison state with states I, II and IIIa of KDIGO in correspondence analysis.

ABSTRACT

Fundamento: La preeclampsia es un estado de vasoconstricción generalizado asociado a la disfunción del epitelio vascular en vez de vasodilatación propia del embarazo, caracterizada por la hipertensión proteinuria a partir de la semana 20, acompañada a veces de edemas; asimismo constituye un peligro de salud para la madre y el feto. El tratamiento clínico tradicional utiliza fármacos antihipertensivos por vía oral, entre los que se mencionan el labetalol y nifedipino de liberación prolongada. Objetivo: Analizar la efectividad del labetalol y del nifedipino como tratamiento antihipertensivo relacionado con preeclampsia. Metodología: Se recurrió a fuentes de consulta encontradas en Google Scholar, Science Direct, SciELO, Pubmed, Medes y Elsevier. De 211 fuentes se seleccionaron 31 de acuerdo con criterios de inclusión y exclusión. Conclusiones: Por consenso se ha determinado que en la mayor parte de fuentes de consulta el nifedipino por vía oral es más efectivo que el labetalol en el tratamiento de la preeclampsia.


Background: Pre-eclampsia is a generalized vasoconstriction state associated with vascular epithelial dysfunction rather than the vasodilation characteristic of pregnancy, characterized by proteinuric hypertension from the 20th week of pregnancy, sometimes associated with edema; it also causes health risks to the mother and fetus. Traditional clinical treatment uses oral antihypertensive drugs, among these labetalol and extended-release nifedipine are included. Objective: To analyze the efficacy of labetalol and nifedipine as an antihypertensive treatment in pre-eclampsia. Methodology: Reference sources found in Google Scholar, Science Direct, SciELO, Pubmed, Medes and Elsevier were used. Out of 211 sources, 31 were selected according to inclusion and exclusion criteria. Conclusions: It has been determined by majority consensus that oral nifedipine is more effective than labetalol in pre-eclampsia treatment.

ABSTRACT

Objetivo: Analisar a tendência temporal de nascimentos prematuros no estado de Santa Catarina entre 2011 e 2021. Métodos: Estudo observacional ecológico de tendência temporal realizado com informações do banco de dados do Sistema de Informação sobre Nascidos Vivos do estado de Santa Catarina (2011-2021), disponibilizado pela Diretoria de Vigilância Epidemiológica. Foram analisados todos os nascidos vivos prematuros segundo o ano de processamento e o local de residência em Santa Catarina (110.422). Foram incluídos os nascidos vivos de gestação com menos de 37 semanas completas. As taxas de nascimentos prematuros foram calculadas proporcionalmente à totalidade de nascimentos e calculadas segundo macrorregião, idade materna, número de consultas do pré-natal, instrução materna e cor de pele. Para o cálculo da tendência temporal, foi utilizada a regressão linear simples, com intervalo de confiança de 95% (p ≤ 0,05). Resultados: A taxa média de nascimentos prematuros no estado de Santa Catarina foi de 10,57%, com tendência estável (p < 0,001). Maiores taxas específicas foram encontradas nas macrorregiões Meio Oeste e Serra e Planalto Norte e Nordeste (11,46%), extremos de idade (10-14 anos e 45-64 anos) e menor escolaridade. Maior número de consultas de pré-natal apresentou taxa de prematuridade menor (7,69%). Tendências crescentes das taxas foram apenas encontradas na macrorregião Grande Oeste, faixa etária materna entre 40-44 anos e entre 4-6 consultas de pré-natal. Conclusão: A tendência da taxa de prematuridade manteve-se estável em Santa Catarina. Baixo número de consultas de pré-natal, extremos de idades e baixa escolaridade mostraram taxas maiores de prematuridade. (AU)


Objective: Analyzing the temporal trend of premature births in the state of Santa Catarina between 2011 and 2021. Methods: Observational ecological temporal trend study carried out with information from the database of the Information System on Live Births in the state of Santa Catarina (2011-2021), made available by the Epidemiological Surveillance Directorate. All premature live births were analyzed according to the year of processing and place of residence in Santa Catarina (110,422). Live births of less than 37 completed weeks were included. The rates of premature births were calculated in proportion to the total number of births and calculated according to macro-region, maternal age, number of prenatal consultations, maternal education and skin color. Simple linear regression was used to calculate the temporal trend, with a confidence interval of 95% (p ≤ 0.05). Results: The average rate of premature births in the state of Santa Catarina was 10.57%, with a stable trend (p < 0.001). Higher specific rates were found in the Midwest and Serra, North Plateau and Northeast macro-regions (11.46%), age extremes (10-14 years and 45-64 years) and lower schooling. A greater number of prenatal consultations had a lower prematurity rate (7.69%). Increasing trends in rates were only found in the Grande Oeste macro-region, maternal age group between 40-44 years and between 4-6 prenatal consultations. Conclusion: The prematurity rate trend remained stable in Santa Catarina. Low number of prenatal consultations, extremes of age and low education showed higher rates of prematurity. (AU)

ABSTRACT

Abstract Objective: To review the literature and synthesize evidence on pathophysiological interactions attributed to the simultaneous occurrence of COVID-19 and preeclampsia. Methods: A systematic review was conducted from November (2021) to January (2022) to retrieve observational studies published on the PubMed, LILACS, SciELO Brazil and Google Scholar databases. The search was based on the descriptors [(eclampsia OR preeclampsia) AND (COVID-19)]. Quantitative studies that pointed to pathophysiological interactions were included. Literature reviews, studies with HIV participants, or with clinical approach only were excluded. The selection of studies was standardized and the evaluation was performed by pairs of researchers. Results: In this review, 155 publications were retrieved; 16 met the inclusion criteria. In summary, the physiological expression of angiotensin-converting enzyme-2 (ACE-2) receptors is physiologically increased in pregnant women, especially at the placental site. Studies suggest that the coronavirus binds to ACE-2 to enter the human cell, causing deregulation of the renin-angiotensin-aldosterone system and in the ratio between angiotensin-II and angiotensin-1-7, inducing manifestations suggestive of preeclampsia. Furthermore, the cytokine storm leads to endothelial dysfunction, vasculopathy and thrombus formation, also present in preeclampsia. Conclusion: The studies retrieved in this review suggest that there is a possible overlap of pathophysiological interactions between COVID-19 and preeclampsia, which mainly involve ACE-2 and endothelial dysfunction. Given that preeclampsia courses with progressive clinical and laboratory alterations, a highly quality prenatal care may be able to detect specific clinical and laboratory parameters to differentiate a true preeclampsia superimposed by covid-19, as well as cases with hypertensive manifestations resulting from viral infection.


Resumo Objetivo: Revisar a literatura e sintetizar evidências sobre interações fisiopatológicas atribuídas à ocorrência simultânea de COVID-19 e pré-eclâmpsia. Métodos: Uma revisão sistemática foi conduzida entre novembro (2021) a janeiro (2022) para recuperar estudos observacionais publicados no PubMed, LILACS, SciELO Brasil e Google scholar. A busca foi baseada nos descritores [(eclâmpsia OR pré-eclâmpsia) AND (COVID-19)]. Estudos quantitativos que apontaram interações fisiopatológicas foram incluídos. Estudos de revisão, com participante HIV e apenas com enfoque clínico foram excluídos. A seleção dos estudos foi padronizada com avaliação por duplas de pesquisadores. Resultados: Nesta revisão, 155 publicações foram recuperadas; 16 preencheram os critérios de inclusão. Em síntese, a expressão fisiológica de receptores da enzima conversora da angiotensina-2 (ECA-2) é fisiologicamente potencializada em gestantes, especialmente no sítio placentário. Os estudos sugerem que o coronavírus se liga à ECA-2 para entrar na célula humana, ocasionando desregulação do sistema renina-angiotensina-aldosterona e da razão entre angiotensina-II e angiotensina-1-7, induzindo manifestações sugestivas de pré-eclâmpsia. Ademais, a tempestade de citocinas conduz à disfunção endotelial, vasculopatia e formação de trombos, também presentes na pré-eclâmpsia. Conclusão: Os estudos recuperados nesta revisão sugerem que a superposição de alterações fisiopatológicas entre a COVID-19 e a pré-eclâmpsia envolve, principalmente, a ECA-2 e disfunção endotelial. Tendo em vista que a pré-eclâmpsia cursa com alterações clínicas e laboratoriais progressivas, a atenção pré-natal de qualidade pode ser capaz de detectar parâmetros clínicos e laboratoriais importantes para diferenciar a pré-eclâmpsia verdadeira sobreposta por COVID-19, bem como os casos que mimetizam a doença hipertensiva consequente à infecção viral.

ABSTRACT

No início do século 20, as altas taxas de mortalidade materna e infantil estimularam o desenvolvimento de um modelo de atendimento pré-natal que mantivesse características parecidas até os dias atuais. Nesse modelo, haveria maior concentração de visitas durante o final do terceiro trimestre de gestação, devido às maiores taxas de complicações nas fases finais da gestação e à dificuldade de prever a ocorrência de resultados adversos durante o primeiro trimestre. Atualmente, a avaliação clínica durante o primeiro trimestre, com auxílio da ultrassonografia e marcadores bioquímicos, pode prever uma série de complicações que acometem a gestação, incluindo cromossomopatias, pré-eclâmpsia, restrição de crescimento fetal, anomalias fetais e trabalho de parto pré-termo.


At the beginning of the 20th century, the high rates of maternal and infant mortality stimulated the development of a model of prenatal care that maintained similar characteristics until the present day. In this model, there would be a greater concentration of visits during the end of the third trimester of pregnancy, due to the higher rates of complications in the final stages of pregnancy and the difficulty in predicting the occurrence of adverse outcomes during the first trimester. Currently, clinical evaluation during the first trimester, with the aid of ultrasound and biochemical markers, can predict a series of complications that affect pregnancy, including chromosomal disorders, preeclampsia, fetal growth restriction, fetal anomalies and preterm labor.

ABSTRACT

Introducción: La hipertensión postparto de inicio tardío se presenta desde las 48 horas hasta las 6 semanas postparto, afectando al 2% de los embarazos relacionados o no con antecedentes de hipertensión gestacional. La preeclampsia posparto tiene una incidencia del 5,7% a las 72 horas del parto y está asociada a varios factores maternos como la edad (≥ 35 años), etnia (negra) y obesidad (IMC ≥ 30), presentando mayor riesgo en embarazos múltiples, madres añosas (mayores de 35 años) hogares con bajos ingresos económicos. Los síntomas más frecuentes de esta patología son cefalea, disnea, trastornos visuales y edema periférico.Objetivo: Describir la experiencia en un centro de salud de atención primaria, el manejo de una paciente diagnosticada de preeclampsia posparto de inicio tardío, así como las caracte-rísticas clínicas y factores de riesgo.Presentación del caso: Se presenta el caso de una paciente indígena de 32 años con antece-dente de parto gemelar quien en su control del puerperio a las 72 horas presentó hipertensión arterial, cefalea frontal, edema periférico y proteinuria estableciéndose el diagnóstico de pree-clampsia posparto de inicio tardío. No fue posible la referencia a un segundo nivel de atención por las características culturales de la paciente por lo cual recibió manejo clínico y tratamiento en el primer nivel de atención presentando una evolución favorable sin complicaciones. Conclusiones y recomendaciones: La hipertensión posparto de inicio tardío es una patolo-gía poco frecuente en el puerperio, infradiagnosticada, con complicaciones cardiovasculares a corto y largo plazo, por lo cual su diagnóstico, diferenciación y manejo debe ser óptimo en base a las recomendaciones existentes.


Introduction: Late-onset postpartum hypertension occurs from 48 hours to 6 weeks pos-tpartum, affecting 2% of pregnancies related or not to a history of gestational hypertension. Postpartum preeclampsia has an incidence of 5.7% at 72 hours postpartum and is associa-ted with several maternal factors such as age (≥ 35 years), ethnicity (black) and obesity (BMI ≥ 30), presenting higher risk in multiple pregnancies, elderly mothers (older than 35 years) low-income households. The most frequent symptoms of this pathology are headache, dysp-nea, visual disturbances and peripheral edema.Objective: To describe the experience in a primary care health center, the management of a patient diagnosed with late-onset postpartum preeclampsia, as well as the clinical characte-ristics and risk factors.Case presentation: We present the case of a 32-year-old indigenous patient with a history of twin birth who in her puerperium control at 72 hours presented arterial hypertension, frontal headache, peripheral edema and proteinuria establishing the diagnosis of late-onset pos-tpartum preeclampsia, after which treatment was initiated at the first level of care, making referral difficult due to cultural characteristics. Conclusions and recomendations: Late-onset postpartum hypertension is an infrequent pathology in the puerperium, underdiagnosed, with short and long-term cardiovascular com-plications, so its diagnosis, differentiation and management should be optimal based on existing recommendations

ABSTRACT

Pre-eclampsia is a major public health problem and is one of the main causes of maternal-fetal morbidity. The main objective of this study is to describe the clinical and evolutionary aspects of severe pre-eclampsia. Methods: This was a retrospective, monocentric, descriptive, observational and cross-sectional study of 6 months, from January 01, 2019 to June 30, 2019, conducted at the level of the resuscitation service of the university hospital of gynecology obstetrics Befelatanana (CHU GOB). Results: Three hundred and fourteen (5.10%) cases out of 6153 admissions of severe pre-eclampsia were collected in the study; the average age was 27.29 ±7.47 years. Eclampsia (30.25%, n= 95), retroplacental hematoma (13.38%, n= 42) and acute renal failure (7.96%, n= 25) were the most frequent maternal complications. Maternal prognosis was favorable in 92.36% of cases (n= 290). Maternal death represented 3.18% (n= 10). Prematurity (44.82%, n= 95), fetal hypotrophy (37.26%, n= 79) and fetal asphyxia (14.15%, n= 30) were the most common fetal complications. Fetal death was 26.47% (n= 81). Conclusion: It is necessary to reinforce the information and education of parturients on the first signs for an early detection, diagnosis and management

ABSTRACT

OBJECTIVE@#To investigate the fetal and maternal outcomes, risk factors of disease progression and adverse pregnancy outcomes (APOs) in patients with undifferentiated connective tissue disease (UCTD).@*METHODS@#This retrospective study described the outcomes of 106 pregnancies in patients with UCTD. The patients were divided into APOs group (n=53) and non-APOs group (n=53). The APOs were defined as miscarriage, premature birth, pre-eclampsia, premature rupture of membranes (PROM), intrauterine growth restriction (IUGR), postpartum hemorrhage (PPH), and stillbirth, small for gestational age infant (SGA), low birth weight infant (LBW) and birth defects. The differences in clinical manifestations, laboratory data and pregnancy outcomes between the two groups were compared. Logistic regression analysis was performed to analyze the risk factors for APOs and the progression of UCTD to definitive CTD.@*RESULTS@#There were 99 (93.39%) live births, 4 (3.77%) stillbirths and 3 (2.83%) miscarriage, 20 (18.86%) preterm delivery, 6 (5.66%) SGA, 17 (16.03%) LBW, 11 (10.37%) pre-eclampsia, 7 (6.60%) cases IUGR, 19 (17.92%) cases PROM, 10 (9.43%) cases PPH. Compared with the patients without APOs, the patients with APOs had a higher positive rate of anti-SSA antibodies (73.58% vs. 54.71%, P=0.036), higher rate of leukopenia (15.09% vs. 3.77%, P=0.046), lower haemoglobin level [109.00 (99.50, 118.00) g/L vs. 124.00 (111.50, 132.00) g/L, P < 0.001].Multivariate Logistic regression analysis showed that leucopenia (OR=0.82, 95%CI: 0.688-0.994) was an independent risk factors for APOs in UCTD (P=0.042). Within a mean follow-up time of 5.00 (3.00, 7.00) years, the rate of disease progression to a definite CTD was 14.15%, including 8 (7.54%) Sjögren's syndrome, 4 (3.77%) systemic lupus erythematosus (SLE), 4 (3.77%) rheumatoid arthritis and 1 (0.94%) mixed connective tissue disease. Multivariate Cox proportional risk regression analysis showed that Raynaud phenomenon (HR=40.157, 95%CI: 3.172-508.326) was an independent risk factor for progression to SLE.@*CONCLUSION@#Leukopenia is an independent risk factor for the development of APOs in patients with UCTD. Raynaud's phenmon is a risk factor for the progression of SLE. Tight disease monitoring and regular follow-up are the key measures to prevent adverse pregnancy outcomes and predict disease progression in UCTD patients with pregnancy.

ABSTRACT

Objective: To investigate the impact of obstructive sleep apnea syndrome (OSAS) on pregnancy outcomes, especially the relationship between OSAS and hypertensive disorders in pregnancy (HDP). Methods: A total of 228 pregnant women with high risk of OSAS who underwent sleep monitoring during pregnancy in Peking University People's Hospital from January 2021 to April 2022 were collected by reviewing their medical records for retrospective analysis. According to the diagnosis of OSAS, the pregnant women were divided into OSAS group (105 cases) and non-OSAS group (123 cases). The non-parametric Mann-Whitney U test, χ2 test or Fisher's exact test were used to compare the general data and maternal and fetal outcomes between the two groups, and the occurrence of each type of HDP was further compared. Results: (1) Compared with the non-OSAS group, the median pre-pregnancy body mass index (23.6 vs 27.6 kg/m2) and the proportion of snoring [28.9% (33/114) vs 59.2% (61/103)] in the OSAS group were higher, and the differences were both statistically significant (both P<0.001). (2) The incidence of HDP [67.6% (71/105) vs 39.0% (48/123)] and gestational diabetes mellitus [GDM; 40.0% (42/105) vs 26.8% (33/123)] of pregnant women in the OSAS group were higher than those in the non-OSAS group, and the median delivery week was shorter than that in the non-OSAS group (38.4 vs 39.0 weeks). The differences were all statistically significant (all P<0.05). Between-group differences for the delivery way, postpartum hemorrhage, the rate of intensive care unit admission, preterm birth, small for gestational age infants, neonatal asphyxia, the rate of neonatal intensive care unit admission, newborn birth weight and the proportion of umbilical artery blood pH<7.00 were not statistically significant (all P>0.05). (3) Compared with the non-OSAS group, the incidence of chronic hypertension [11.4% (14/123) vs 22.9% (24/105)] and chronic hypertension with superimposed pre-eclampsia [11.4% (14/123) vs 30.5% (32/105)] were higher in the OSAS group, and the differences were both statistically significant (both P<0.01). Conclusion: OSAS is related to HDP (especially chronic hypertension and chronic hypertension with superimposed pre-eclampsia) and GDM, which could provide a practical basis for the screening, diagnosis and treatment of OSAS in pregnant women at high risk.

ABSTRACT

Preeclampsia and intrauterine growth restriction (IUGR) of the fetus are the two most common pregnancy complications worldwide, affecting 5%-10% of pregnant women. Preeclampsia is associated with significantly increased maternal and fetal morbidity and mortality. Hypoxia-induced uteroplacental dysfunction is now recognized as a key pathological factor in preeclampsia and IUGR. Reduced oxygen supply (hypoxia) disrupts mitochondrial and endoplasmic reticulum (ER) function. Hypoxia has been shown to alter mitochondrial reactive oxygen species (ROS) homeostasis and induce ER stress. Hypoxia during pregnancy is associated with excessive production of ROS in the placenta, leading to oxidative stress. Oxidative stress occurs in a number of human diseases, including high blood pressure during pregnancy. Studies have shown that uterine placental tissue/cells in preeclampsia and IUGR show high levels of oxidative stress, which plays an important role in the pathogenesis of both the complications. This review summarizes the role of hypoxia-induced mitochondrial oxidative stress and ER stress in the pathogenesis of preeclampsia/IUGR and discusses the potential therapeutic strategies targeting oxidative stress to treat both the pregnancy complications.

ABSTRACT

Objective: To explore the associations between blood pressure trajectories during pregnancy and risk of future pre-eclampsia in a large cohort enrolling pregnant women at gestational age of ~12 weeks from community hospitals in Tianjin. Latent class growth modeling (LCGM) was used to model the blood pressure trajectories. Methods: This was a large prospective cohort study. The study enrolled pregnant women of ~12 weeks of gestation in 19 community hospitals in Tianjin from November 1, 2016 to May 30, 2018. We obtained related information during 5 antepartum examinations before gestational week 28, i.e., week 12, week 16, week 20, week 24 and week 28. LCGM was used to model longitudinal systolic (SBP) and diastolic blood pressure (DBP) trajectories. For the association study, the predictors were set as SBP and DBP trajectory membership (built separately), the outcome was defined as the occurrence of preeclampsia after 28 weeks of gestation. Results: A total of 5 809 cases with known pregnant outcomes were documented. After excluding 249 cases per exclusion criteria, 5 560 cases with singleton pregnancy were included for final analysis. There were 128 cases preeclampsia and 106 cases gestational hypertension in this cohort. Univariate logistic regression and multivariate logistic regression showed the higher baseline SBP level and DBP level were related with increased risk of preeclampsia. Four distinctive SBP trajectories and DBP trajectories from 12 weeks to 28 weeks of gestation were identified by LCGM. After controlling for potential confounders (baseline BMI, being primipara or not, white blood cell counts, hemoglobin level, platelet counts and alanine aminotransferase level), the OR for SBP latent classification trajectory_ 4 was 4.023 (95%CI: 2.368 to 6.835, P<0.001), and the OR for SBP latent classification trajectory_3 was 1.854 (95%CI: 1.223 to 2.811, P=0.004). Logistic regression showed that: using the DBP latent classification trajectory_1 as the reference group, the OR for DBP latent classification trajectory_4 was 4.100 (95%CI: 2.571 to 6.538, P<0.001), and 2.632 (95%CI: 1.570 to 4.414, P<0.001) for DBP latent classification trajectory_2. After controlling for potential confounders (baseline BMI, being primipara or not, white blood cell counts, hemoglobin level, platelet counts and alanine aminotransferase level), the OR for DBP_traj_4 was 2.527 (95%CI: 1.534 to 4.162, P<0.001), and the OR for DBP_traj_3 was 1.297 (95%CI: 0.790 to 2.128, P=0.303), and 2.238 (95%CI: 1.328 to 3.772, P=0.002) for DBP_traj_2. Therefore, BP trajectories from 12 weeks to 28 weeks identified by LCGM served as novel risk factors that independently associated with the occurrence of preeclampsia. Receiver operating characteristic (ROC) curve analysis showed incremental diagnostic performance by combing baseline blood pressure levels with blood pressure trajectories. Conclusion: By applying LCGM, we for the first time identified distinctive BP trajectories from gestational week 12 to 28, which can independently predict the development of preeclampsia after 28 weeks of gestation.

ABSTRACT

Objective: To identify the expression profile of circular RNA (circRNA) in placenta of pre-eclampsia (PE) pregnant women by high-throughput sequencing, and to construct the circRNA-microRNA (miRNA)-messenger RNA (mRNA) interaction network, so as to reveal the related pathways and regulatory mechanisms of PE. Methods: The clinical data and placentas of 42 women with PE (PE group) and 30 normal pregnant women (control group) who delivered in West China Second University Hospital from November 2019 to June 2021 were collected. (1) High-throughput sequencing was used to establish the differentially expressed circRNA profiles in placental tissues of 5 pairs of PE group and the control group. (2) Real-time quantitative PCR (qRT-PCR) was used to verify the expression levels of 6 differentially expressed circRNAs in placental tissues of PE group and control group. (3) Bioinformatics analysis was used to predict the target miRNA and analyze the co-expressed mRNA to construct a competitive endogenous RNA (ceRNA) network. The differentially expressed circRNAs were analyzed by Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathways. (4) Logistic regression analysis, Pearson correlation and Kendall's tau-b correlation analysis were used to test the correlation between the three differentially expressed circRNAs and the risk of PE and clinical characteristics. (5) circRNA_05393 was selected for subsequent functional study. Small interfering RNA (siRNA) and overexpression plasmid were used to knock down or increase the expression level of circRNA_05393 in trophoblast cell line HTR-8/SVneo cells, respectively. Transwell assay was used to detect the migration and invasion ability of the trophoblasts in vitro. Cell counting kit-8 assay was used to detect the proliferation ability of the trophoblasts. Results: (1) Seventy-two differentially expressed circRNAs were identified by high-throughput sequencing, of which 35 were up-regulated and 37 were down-regulated. (2) qRT-PCR showed that compared with the control group, circRNA_00673 (1.306±0.168 vs 2.059±0.242; t=2.356, P=0.021) and circRNA_07796 (1.275±0.232 vs 1.954±0.230; t=2.018, P=0.047) were significantly increased, while circRNA_05393 (1.846±0.377 vs 0.790±0.094; t=3.138, P=0.002) was significantly decreased. (3) The circRNA-miRNA-mRNA interaction network contained 3 circRNAs, 8 miRNAs and 53 mRNAs. GO functional annotation analysis showed that the biological process was mainly enriched in iron ion homeostasis, membrane depolarization during action potential and neuronal action potential. In terms of cellular components, they were mainly enriched in cytoskeleton and membrane components. In terms of molecular function, they were mainly enriched in the activity of voltage-gated sodium channel and basic amino acid transmembrane transporter. KEGG pathway enrichment analysis showed that mRNAs in the interaction network were mainly enriched in complement and coagulation cascade, glycine, serine and threonine metabolism, p53 signaling pathway and peroxisome proliferators-activated receptors (PPAR) signaling pathway. (4) Logistic regression analysis showed that down-regulation of circRNA_05393 expression was a risk factor for PE (OR=0.044, 95%CI: 0.003-0.596; P=0.019). Correlation analysis showed that circRNA_05393 was significantly correlated with systolic blood pressure and diastolic blood pressure in PE pregnant women (both P<0.05). (5) Knock down or overexpression of circRNA_05393 significantly reduced or increased the migration and invasion abilities of HTR-8/SVneo cells (all P<0.05), but had no significant effect on the ability of tube formation and proliferation (all P>0.05). Conclusions: The construction of circRNA expression profile in placenta and the exploration of circRNA-miRNA-mRNA interaction network provide the possibility to reveal the regulatory mechanism of specific circRNA involved in PE. Inhibition of circRNA_05393 may induce the progression of PE by reducing the migration and invasion of trophoblasts.

ABSTRACT

Objective: To explore the key points for preventing and reducing severe pre-eclampsia (SPE) and its severe complications in the tertiary medical referral system of a second-tier city by analyzing the clinical characteristics of SPE. Methods: The clinical data of 341 patients with SPE who terminated pregnancy in Women and Children's Hospital, School of Medicine, Xiamen University, from January 1, 2020 to December 31, 2022 were retrospectively analyzed, and the pre-eclampsia (PE) risk factors, clinical characteristics and severe complications of SPE between the patients referred from primary hospitals (referral group) and the patients received regular prenatal care in the tertiary referral center (central group) were compared, as well as the influence of the referral timing on the maternal and perinatal outcomes. Results: Among the 341 cases of SPE, 92 cases were in the referral group and 249 cases were in the central group. (1) Analysis of PE risk factors: there was no statistical difference in the proportion of risk factors of PE between these two groups [75.0% (69/92) vs 71.9% (179/249); χ2=0.328, P=0.567]. (2) Analysis of clinical features: the gestational ages at the PE early warning factors onset, at the PE first symptom onset and at SPE diagnosed, pregnancy terminated and onset of SPE severe complications in the referral group were significantly earlier than those in the central group (all P<0.05), the proportions of terminating pregnancy before 32 weeks of gestation, between 32 and 34 weeks of gestation, intensive care unit (ICU), neonatal ICU hospitalization and fetal growth restriction in single pregnancies were higher than those in the central group, while the live birth rate was lower than that in the central group (all P<0.05). (3) Analysis of SPE severe complications: the rates of SPE severe complications in the referral group was higher than that in the central group [28.3% (26/92) vs 13.7% (34/249); χ2=9.885, P=0.002]. Among them, the rates of placental abruption [7.6% (7/92) vs 2.8% (7/249); χ2=3.927, P=0.048] and still birth [6.5% (6/92) vs 0.4% (1/249); χ2=9.656, P=0.002] in the referral group were significantly higher than those in the central group. (4) Analysis of referral timings: the timings included referral after onset of SPE severe complications (9.8%, 9/92), referral after SPE diagnosed (63.0%, 58/92), referral after detection of SPE early warning signs (20.7%, 19/92) and referral after detection of PE risk factors (6.5%, 6/92). The gestational ages at SPE diagnosed and pregnancy terminated in group of referral after onset of SPE severe complications and group of referral after SPE diagnosed were significantly earlier than those in group of referral after detection of PE early warning signs and group of referral after detection of PE risk factors (P<0.05). The earlier the referral, the higher the live birth rates (P<0.05). Conclusions: The tertiary referral center of the second-tier city plays an important role in reducing the maternal and perinatal damage of PE. The timing of referral in primary medical institutions is the key point of reducing the occurrence of SPE severe complications and maternal, perinatal damage of PE. It is necessary for medical institutions of all levels in all regions to improve the ability of early identification and early intervention for PE, to enhance the awareness of SPE and its severe complications prevention and control. Primary medical institutions should especially pay attention to raise the consciousness of PE risk factors and early warning signs, and to improve the ability of PE risk factors and early warning signs screening.

ABSTRACT

Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.
