RESUMO
OBJECTIVES: This study aimed to assess the factors influencing pregnant women's participation in perinatal education and their demand for educational courses. DESIGN: A cross-sectional study. SETTING: Tertiary hospital in Suzhou, China, July-September 2022. PARTICIPANTS: Pregnant women from a general grade A tertiary hospital in Suzhou were recruited via online survey invitations during the specified period. MEASURES: A self-designed scale was used to evaluate pregnant women's demand for perinatal education. Multiple response sets were employed for the assessment of multiple-choice items and analyses included frequency and cross-tabulation. Logistic regression analysis was conducted to assess the factors influencing pregnant women's participation in perinatal education. OUTCOME: The primary outcome measured was the demand for perinatal education among pregnant women. RESULTS: A majority (53.8%) of pregnant women expressed a preference for a mixed teaching mode combining online and offline formats. Logistic regression analysis showed that education level significantly influenced pregnant women's participation in online learning. Specifically, women with higher education levels were more likely to participate actively in online courses. Additionally, compared with those with first-born children, pregnant women with second-born children participated less actively in online learning. Pregnant women in their second and third trimesters showed greater engagement in online learning compared with those in their first trimester. CONCLUSIONS: These findings indicate that Chinese pregnant women's preferences for perinatal education are influenced by their educational background, pregnancy history and the mode of teaching employed. The variability in educational needs underscores the importance of regularly updating course content based on participant feedback.

OBJECTIVES: Endometriosis is one of the leading causes of infertility, due to negative impact on ovarian folliculogenesis and endometrial receptivity. Literature show that endometriosis could be associated with perinatal complications such as preterm birth (PTB) and preeclampsia (PE). Authors hypothesized that women with endometriosis-related infertility conceived by assisted reproductive technology (ART) treatment have higher frequency of placental disorders. Main outcome is the occurrence of histopathologic alterations of term placentas in singleton pregnancies of women with endometriosis conceived by ART treatment, compared to healthy women with infertility due to male factor (MF) conceived by ART and to healthy women with spontaneous pregnancies. Secondary outcome include the occurrence of perinatal complications and the relationship of endometriosis and placental histopathologic characteristics. METHODS: Single-center, case-control study of term placentas that were collected within Department of Obstetrics and Gynecology of University Hospital Center (UHC) Split and analyzed in the Pathology department of the same hospital, by one senior perinatal pathologist. Histopathologic analysis was reported using Amsterdam Placental Workshop Group Consensus. All the noted placental lesions were divided into following categories: anatomic, inflammatory, villous maturation and vascular malperfusion disorders. Required sample size was 80 placentas, and study results were reported with descriptives, and analyzed with chi-squared, Fisher's exact test and Kruskal-Wallis ANOVA. Multivariate regression analysis was carried with adjustment for confounding factors. Ethics approval: Class n. 520-03/24-01/83. RESULTS: Study included term placentas of 107 women, of which 36 were women with endometriosis conceived by ART, 31 were healthy women with MF infertility conceived by ART and 40 healthy women with spontaneous pregnancies. Endometriosis women were predominantly primiparas, with longer infertility duration. Endometriosis group had higher occurrence of early pregnancy bleeding and imminent preterm labor. Endometriosis and MF groups had higher occurrence of Cesarian delivery (CS), while endometriosis group had newborns with lowest birthweight. Endometriosis group had shorter placental cords (PC), higher rates of increased syncytial knotting and vascular malperfusion disorders (subchorionic and perivillous fibrin, intervillous thrombosis, high grade fetal vascular malperfusion). Finally, endometriosis is showed to be associated with increased syncytial knots' formation and PC hypercoiling, after adjustment for confounding factors in the multivariate regression analysis. CONCLUSIONS: Despite low rates of perinatal complications, we report endometriosis to have higher occurrence of increased syncytial knotting and vascular malperfusion placental disorders, compared to control groups. Endometriosis is also associated with increased syncytial knotting and PC hypercoiling. Further studies are needed to elucidate the endometriosis impact on endometrial receptivity and immunopathogenesis in placental disorders and perinatal complications.HighlightsEndometriosis women were predominantly primiparas, with longer infertility duration.Endometriosis group had higher occurrence of early pregnancy bleeding and imminent preterm labor. Moreover, endometriosis and MF groups had higher occurrence of Cesarian delivery, while endometriosis group had newborns with lowest birthweight.Endometriosis group had shorter placental cords, higher rates of increased syncytial knotting and vascular malperfusion lesions.Endometriosis is showed to be associated with increased syncytial knots formation and hypercoiling of placental cord, after adjustment for confounding factor.

OBJECTIVE: Define and develop a set of entrustable professional activities (EPAs) to link clinical training and assessment of the hospital components of neonatal care in neonatology medical residency programs. METHODS: An exploratory study was conducted in two phases using a modified Delphi approach. In the first phase, a committee of five neonatology residency program coordinators drafted an initial set of EPAs based on the national matrix of competencies and on EPAs defined by international organizations. In the second phase, a group of neonatal care physicians and medical residents rated the indispensability and clarity of the EPAs and provided comments and suggestions. RESULTS: Seven EPAs were drafted by the coordinators´ committee (n = 5) and used in the content validation process with a group (n = 37) of neonatal care physicians and medical residents. In the first Delphi round, all EPAs reached a content validity index (CVI) above 0.8. The coordinators´ committee analyzed comments and suggestions and revised the EPAs. A second Delphi round with the revised EPAs was conducted to validate and all items maintained a CVI above 0.8 for indispensability and clarity. CONCLUSION: Seven entrustable professional activities were developed to assess residents in the hospital components of neonatal care medicine. These EPAs might contribute to implementing competency-based neonatology medical residency programs grounded in core professional activities.
RESUMO
OBJECTIVES: This study investigated changes in the length of stay (LoS) at a level III/IV neonatal intensive care unit (NICU) and level II neonatology departments until discharge home for very preterm infants and identified factors influencing these trends. DESIGN: Retrospective cohort study based on data recorded in the Netherlands Perinatal Registry between 2008 and 2021. SETTING: A single level III/IV NICU and multiple level II neonatology departments in the Netherlands. PARTICIPANTS: NICU-admitted infants (n=2646) with a gestational age (GA) <32 weeks. MAIN OUTCOME MEASURES: LoS at the NICU and overall LoS until discharge home. RESULTS: The results showed an increase of 5.1 days (95% CI 2.2 to 8, p<0.001) in overall LoS in period 3 after accounting for confounding variables. This increase was primarily driven by extended LoS at level II hospitals, while LoS at the NICU remained stable. The study also indicated a strong association between severe complications of preterm birth and LoS. Treatment of infants with a lower GA and more (severe) complications (such as severe retinopathy of prematurity) during the more recent periods may have increased LoS. CONCLUSION: The findings of this study highlight the increasing overall LoS for very preterm infants. LoS of very preterm infants is presumably influenced by the occurrence of complications of preterm birth, which are more frequent in infants at a lower gestational age.

OBJECTIVES: To assess the reporting and methodological quality of early-life policy intervention papers that applied difference-in-differences (DiD) analysis. STUDY DESIGN: Systematic review. DATA SOURCES: Papers applying DiD of early-life policy interventions in high-income countries as identified by searching Medline, Embase and Scopus databases up to December, 2022. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS: Studies evaluating policy interventions targeting expectant mothers, infants or children up to two years old and conducted in high income countries were included. We focused on seven critical conditions of DiD as proposed in a comprehensive checklist: data requirements, parallel trends, no-anticipation, standard statistical assumptions, common shocks, group composition and spillover. RESULTS: The DiD included studies (n=19) evaluating early-life policy interventions in childhood development (n=4), healthcare utilisation and providers (n=4), nutrition programmes (n=3) and economic policies such as prenatal care expansion (n=8). Although none of the included studies met all critical conditions, the most reported and adhered to critical conditions were data requirements (n=18), standard statistical assumptions (n=11) and the parallel trends assumption (n=9). No-anticipation and spillover were explicitly reported and adhered to in two studies and one study, respectively. CONCLUSIONS: This review highlights current deficiencies in the reporting and methodological quality of studies using DiD to evaluate early-life policy interventions. As the validity of study conclusions and consequent implications for policy depend on the extent to which critical conditions are met, this shortcoming is concerning. We recommend that researchers use the described checklist to improve the transparency and validity of their evaluations. The checklist should be further refined by adding order of importance or knock-out criteria and may also help facilitate uniform terminology. This will hopefully encourage reliable DiD evaluations and thus contribute to better policies relating to expectant mothers, infants and children.

OBJECTIVES: The objective was to investigate the associations of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) trajectories with adverse pregnancy outcomes (APOs). DESIGN: This was a prospective cohort study. SETTING: This study was conducted in Shanghai Pudong New Area Health Care Hospital for Women and Children, Shanghai, China. PRIMARY AND SECONDARY OUTCOME MEASURES: A cohort study involving a total of 2174 pregnant women was conducted. Each participant was followed to record weekly weight gain and pregnancy outcomes. The Institute of Medicine classification was used to categorise prepregnancy BMI, and four GWG trajectories were identified using a latent class growth model. RESULTS: The adjusted ORs for the risks of large for gestational age (LGA), macrosomia, gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) were significantly greater for women with prepregnancy overweight/obesity (OR=1.77, 2.13, 1.95 and 4.24; 95% CI 1.3 to 2.42, 1.32 to 3.46, 1.43 to 2.66 and 2.01 to 8.93, respectively) and lower for those who were underweight than for those with normal weight (excluding HDP) (OR=0.35, 0.27 and 0.59; 95% CI 0.22 to 0.53, 0.11 to 0.66 and 0.36 to 0.89, respectively). The risk of small for gestational age (SGA) and low birth weight (LBW) was significantly increased in the underweight group (OR=3.11, 2.20; 95% CI 1.63 to 5.92, 1.10 to 4.41; respectively) compared with the normal-weight group; however, the risk did not decrease in the overweight/obese group (p=0.942, 0.697, respectively). GWG was divided into four trajectories, accounting for 16.6%, 41.4%, 31.7% and 10.3% of the participants, respectively. After adjustment for confounding factors, the risk of LGA was 1.54 times greater for women in the slow GWG trajectory group than for those in the extremely slow GWG trajectory group (95% CI 1.07 to 2.21); the risk of SGA and LBW was 0.37 times and 0.46 times lower for women in the moderate GWG trajectory group and 0.14 times and 0.15 times lower for women in the rapid GWG trajectory group, respectively; the risk of macrosomia and LGA was 2.65 times and 2.70 times greater for women in the moderate GWG trajectory group and 3.53 times and 4.36 times greater for women in the rapid GWG trajectory group, respectively; and the women in the other three trajectory groups had a lower risk of GDM than did those in the extremely slow GWG trajectory group, but there was not much variation in the ORs. Notably, different GWG trajectories did not affect the risk of HDP. CONCLUSIONS: As independent risk factors, excessively high and low prepregnancy BMI and GWG can increase the risk of APOs.

Low blood concentrations of glucose (hypoglycaemia) soon after birth are common because of the delayed metabolic transition from maternal to endogenous neonatal sources of glucose. Because glucose is the main energy source for the brain, severe hypoglycaemia can cause neuroglycopenia (inadequate supply of glucose to the brain) and, if severe, permanent brain injury. Routine screening of infants at risk and treatment when hypoglycaemia is detected are therefore widely recommended. Robust evidence to support most aspects of management is lacking, however, including the appropriate threshold for diagnosis and optimal monitoring. Treatment is usually initially more feeding, with buccal dextrose gel, followed by intravenous dextrose. In infants at risk, developmental outcomes after mild hypoglycaemia seem to be worse than in those who do not develop hypoglycaemia, but the reasons for these observations are uncertain. Here, the current understanding of the pathophysiology of neonatal hypoglycaemia and recent evidence regarding its diagnosis, management, and outcomes are reviewed. Recommendations are made for further research priorities.
RESUMO
OBJECTIVES: Maternal smoking during pregnancy is associated with low birth weight (LBW). Reduction of cigarette consumption does not seem to improve birth weight but it is not known whether implementation of periods of smoking abstinence improves it. We assessed whether the number of 7-day periods of smoking abstinence during pregnancy may help reduce the number of newborns with LBW. DESIGN AND SETTING: Secondary analysis of a randomised, controlled, multicentre, smoking cessation trial among pregnant smokers. PARTICIPANTS: Pregnant women were included at <18 weeks of gestational age and assessed at face-to-face, monthly visits. Data of 407 singleton live births were analysed. PRIMARY OUTCOME MEASURE: Newborns with low birth weight. RESULTS: 40 and 367 newborns were born with and without LBW, respectively. Adjusted for all available confounders, 3 or more periods of at least 7 days' smoking abstinence during pregnancy was associated with reduced likelihood of LBW compared with no abstinence periods (OR = 0.124, 95% CI 0.03 to 0.53, p = 0.005). Reduction of smoking intensity by at least 50% was not associated with birth weight. CONCLUSION: Aiming for several periods of smoking abstinence among pregnant smokers unable to remain continuously abstinent from smoking may be a better strategy to improve birth weight than reducing cigarette consumption. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT02606227.

BACKGROUND: Myelomeningocele (MMC) is a neural tube defect disease. Antenatal repair of fetal MMC is an alternative to postnatal repair. Many agents can be used as tocolytics during the in utero fetal repair such as ß2-agonists and oxytocin receptor antagonists, with possible maternal and fetal repercussions. This study aims to compare maternal arterial blood gas analysis between terbutaline or atosiban, as tocolytic agents, during intrauterine MMC repair. METHODS: Retrospective cohort study. Patients were divided into two groups depending on the main tocolytic agent used during intrauterine MMC repair: atosiban (16) or terbutaline (9). Maternal arterial blood gas samples were analyzed on three moments: post induction (baseline, before the start of tocolysis), before extubation, and two hours after the end of the surgery. RESULTS: Twenty-five patients were included and assessed. Before extubation, the terbutaline group showed lower arterial pH (7.347 ± 0.05 vs. 7.396 ± 0.02 for atosiban, p = 0.006) and higher arterial lactate (28.33 ± 12.76 mg.dL-1 vs. 13.06 ± 6.35 mg.dL-1, for atosiban, p = 0.001) levels. CONCLUSIONS: Patients who received terbutaline had more acidosis and higher levels of lactate, compared to those who received atosiban, during intrauterine fetal MMC repair.

INTRODUCTION: Perinatal mortality remains a pressing concern, especially in lower and middle-income nations. Globally, 1 in 72 babies are stillborn. Despite advancements, the 2030 targets are challenging, notably in sub-Saharan Africa. Post-war Liberia saw a 14% spike in perinatal mortality between 2013 and 2020, indicating the urgency for in-depth study. OBJECTIVE: The study aims to investigate the predictors of perinatal mortality in Liberia using 2013 and 2019-2020 Liberia Demographic and Health Survey datasets. METHODS: In a two-stage cluster design from the Liberia Demographic and Health Survey, 6572 and 5285 respondents were analysed for 2013 and 2019-2020, respectively. Data included women aged 15-49 with pregnancy histories. Descriptive statistics was used to analyse the sociodemographic characteristics, the exposure to media and the maternal health services. Bivariate and multivariate logistic regressions were used to examine the predictors of perinatal mortality at a significance level of p value ≤0.05 and 95% CI. The data analysis was conducted in STATA V.14. RESULTS: Perinatal mortality rates increased from 30.23 per 1000 births in 2013 to 42.05 in 2019-2020. In 2013, increasing age of respondents showed a reduced risk of perinatal mortality rate. In both years, having one to three children significantly reduced mortality risk (2013: adjusted OR (aOR) 0.30, 95% CI 0.14 to 0.64; 2019: aOR 0.24, 95% CI 0.11 to 0.54), compared with not having a child. Weekly radio listenership increased mortality risk (2013: aOR 1.36, 95% CI 0.99 to 1.89; 2019: aOR 1.86, 95% CI 1.35 to 2.57) compared with not listening at all. Longer pregnancy intervals (p<0.0001) and receiving 2+ tetanus injections (p=0.019) were protective across both periods. However, iron supplementation showed varied effects, reducing risk in 2013 (aOR 0.90, 95% CI 0.48 to 1.68) but increasing it in 2019 (aOR 2.10, 95% CI 0.90 to 4.92). CONCLUSION: The study reports an alarming increase in Liberia's perinatal mortality from 2013 to 2019-2020. The findings show dynamic risk factors necessitating adaptable healthcare approaches, particularly during antenatal care. These adaptable approaches are crucial for refining health strategies in line with the Sustainable Development Goals, with emphasis on the integration of health, education, gender equality, sustainable livelihoods and global partnerships for effective health outcomes.

INTRODUCTION: COVID-19 is associated with higher morbimortality in pregnant people compared with non-pregnant people. At present, the benefits of maternal immunisation are considered to outweigh the risks, and therefore, vaccination is recommended during pregnancy. However, additional information is needed on the safety of the vaccines in this population. METHODS AND ANALYSIS: This a retrospective cohort nested case-control study in pregnant people who attended maternity hospitals from eight Latin American and Caribbean countries. A perinatal electronic clinical history database with neonatal and obstetric information will be used. The proportion of pregnant people immunised with COVID-19 vaccines of the following maternal and neonatal events will be described: preterm infant, small for gestational age, low birth weight, stillbirth, neonatal death, congenital malformations, maternal near miss and maternal death. Moreover, the risk of prematurity, small for gestational age and low birth weight associated with exposure to COVID-19 vaccines will be estimated. Each case will be matched with two groups of three randomly selected controls. Controls will be matched by hospital and mother's age (±3 years) with an additional matching by delivery date and conception time in the first and second control groups, respectively. The estimated required sample size for the main analysis (exposure to any vaccine) concerning 'non-use' is at least 1009 cases (3027 controls) to detect an increased probability of vaccine-associated event risk of 30% and at least 650 cases (1950 controls) to detect 30% protection. Sensitivity and secondary analyses considering country, type of vaccine, exposure windows and completeness of immunisation will be reported. ETHICS: The study protocol was reviewed by the Ethical Review Committee on Research of the Pan American Health Organization. Patient informed consent was waived due to the retrospective design and the utilisation of anonymised data (Ref. No: PAHOERC.0546.01). Results will be disseminated in open access journals.

OBJECTIVES: To determine whether integrated maternity care is associated with reduced preterm births (PTB) and fewer small-for-gestational-age infants (SGA), and whether its implementation leads to a reduction of secondary care consultations. DESIGN: Retrospective study. SETTING: Integrated maternity care organisation in the southwestern region of the Netherlands. PARTICIPANTS: All singleton pregnancies (≥24 weeks) within integrated maternity care organisation Annature between 2015 and 2020. INTERVENTION: Implementation of a shared maternity record in primary and secondary care. METHODS: Data of 20 818 women were derived from patient records and from the Netherlands Perinatal Registry. Intervention was the introduction of integrated maternity care in January 2018. Through multivariate logistic regression and segmented regression analysis we assessed the combined prevalence of SGA and PTB (SGA-PTB) before (2015-2017), and after the intervention (2018-2020). Regional rates were contrasted with nationwide rates (n=782 176). MAIN OUTCOME MEASURES: SGA-PTB prevalence and mean number of secondary care consultations per pregnancy. RESULTS: SGA-PTB prevalence declined from 618/3443 (17.9%) in 2015 to 560/3501 (16.0%) in 2017 to 507/3459 (14.7%) in 2020 (p<0.005). Mean number of secondary care consultations declined from six per pregnancy in 2015 to three in 2020. Logistic regression demonstrated a significant decline in odds of SGA-PTB (OR 0.83 (95% CI 0.77 to 0.89)) between 2015-2017 and 2018-2020 adjusted for changes in sociodemographic characteristics over time. A statistically significant average monthly 7.3% (p=0.05) reduction in SGA-PTB prevalence and 12.4% (p<0.005) mean monthly reduction in secondary care consultations were demonstrated for 2015-2017. Immediately after the intervention, mean monthly prevalence of SGA-PTB dropped non-significantly to 14.7%. Between 2018 and 2020 a significant 15.2% (p<0.005) reduction in secondary care consultations was shown. CONCLUSION: Our results suggest that implementation of integrated maternity care was associated with reduced PTBs and/or low birth weight, and fewer secondary care consultations. These encouraging findings were observed in a less favourable sociodemographic profile and should be confirmed in other regions with sufficiently large populations, and the possibility to test individual components of integrated maternity care.

INTRODUCTION: Integrated care is seen as an enabling strategy in organising healthcare to improve quality, finances, personnel and sustainability. Developments in the organisation of maternity care follow this trend. The way care is organised should support the general aims and outcomes of healthcare systems. Organisation itself consists of a variety of smaller 'elements of organisation'. Various elements of organisation are implemented in different organisations and networks. We will examine which elements of integrated maternity care are associated with maternal and neonatal health outcomes, experiences of women and professionals, healthcare spending and care processes. METHODS AND ANALYSIS: We will conduct this review using the JBI methodology for scoping reviews and the reporting guideline PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews). We will undertake a systematic search in the databases PubMed, Scopus, Cochrane and PsycINFO. A machine learning tool, ASReview, will be used to select relevant papers. These papers will be analysed and classified thematically using the framework of the Rainbow Model of Integrated Care (RMIC). The Population Concept Context framework for scoping reviews will be used in which 'Population' is defined as elements of the organisation of integrated maternity care, 'Context' as high-income countries and 'Concepts' as outcomes stated in the objective of this review. We will include papers from 2012 onwards, in Dutch or English language, which describe both 'how the care is organised' (elements) and 'outcomes'. ETHICS AND DISSEMINATION: Since this is a scoping review of previously published summary data, ethical approval for this study is not needed. Findings will be published in a peer-reviewed international journal, discussed in a webinar and presented at (inter)national conferences and meetings of professional associations.The findings of this scoping review will give insight into the nature and effectiveness of elements of integrated care and will generate hypotheses for further research.

RESUMO
INTRODUCTION: Interpregnancy weight change may impact two important adverse perinatal outcomes: stillbirth and infant mortality. This systematic review aims to synthesise the existing evidence on the association between interpregnancy weight change and stillbirth and infant mortality. METHODS AND ANALYSIS: This systematic review and meta-analysis will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols guidelines and has been registered in the International Prospective Register of Systematic Reviews (PROSPERO). A comprehensive literature search of four online databases (Embase, Cochrane Libraries, Web of Science and Medline) will be conducted from inception to October 2023. Observational (longitudinal, cohort, case-control) and randomised controlled trials will be included. Interpregnancy weight/body mass index change between two consecutive pregnancies will be the exposure. The primary outcomes will be the incidence of stillbirth and infant mortality in subsequent pregnancy. The Cochrane Risk of Bias tool will be used to assess the risk of bias in the randomised controlled studies and the Risk of Bias in Non-Randomised Studies of Interventions tool will be used for observational studies. If there are sufficient data, a meta-analysis will be conducted to estimate the pooled effect size. Otherwise, qualitative descriptions of individual studies will be summarised. The heterogeneity will be statistically assessed using a χ2 test and I2 statistic. ETHICS AND DISSEMINATION: Ethics approval is not required for this study as all results will be based on published papers. No primary data collection will be needed. Study findings will be presented at scientific conferences or published in a peer-reviewed scientific journal. TRIAL REGISTRATION NUMBER: A registration for this review has been submitted to PROSPERO under CRD42020222977.

ABSTRACT Objectives: To analyze the perinatal outcomes of Perinatally acquired HIV Infection (PHIV) in pregnant women. Method: This retrospective cohort study included singleton pregnancies in Women Living with HIV (WLH) between 2006 and 2019. Patient charts were revised, and maternal characteristics, type of HIV infection (perinatal vs. behavioral), Antiretroviral Therapy (ART) exposure, and obstetric and neonatal outcomes were assessed. The HIV-related aspects considered were: Viral Load (VL), CD4+ cell count, opportunistic infections, and genotype testing. Laboratory analyses were performed at baseline (first appointment) and 34 weeks of gestation. Results: There were 186 WLH pregnancies, and 54 (29%) patients had PHIV. Patients with PHIV were younger (p < 0.001), had less frequently stable partnerships (p < 0.001), had more commonly serodiscordant partners (p < 0.001), had a longer time on ART (p < 0.001), and had lower rates of undetectable VL at baseline (p = 0.046) and at 34 weeks of gestation (p < 0.001). No association was observed between PHIV and adverse perinatal outcomes. Among patients with PHIV, third trimester anemia was associated with preterm birth (p = 0.039). Genotype testing was available only for 11 patients with PHIV, who presented multiple mutations related to ART resistance. Conclusions: PHIV did not seem to increase the risk of adverse perinatal outcomes. However, PHIV pregnancies have a higher risk of viral suppression failure and exposure to complex ARTs.

Resumen OBJETIVO: Validar el rendimiento de la calculadora de la Fundación de Medicina Fetal 4.0 adaptada a población mexicana. MATERIALES Y MÉTODOS: Estudio de cohorte efectuado en embarazos con feto único, según el modelo de riesgos en competencia para preeclampsia en un centro de medicina fetal de la Ciudad de México. El riesgo a priori se calculó de acuerdo con la historia clínica. La presión arterial media, el índice de pulsatilidad medio de la arteria uterina y la proteína plasmática A asociada al embarazo se midieron a las 11 a 14 semanas de gestación con metodología estandarizada. El valor de cada marcador se transformó en múltiplos de la mediana adaptados a la población local. Se aplicaron la distribución normal multivariante y el teorema de Bayes para obtener las probabilidades posprueba individuales, que se utilizaron como clasificadores para el área bajo la curva de característica receptor-operador. RESULTADOS: La incidencia de preeclampsia fue del 5.0% (54/1078). El área bajo la curva de característica receptor-operador fue de 0.784 (0.712; 0.856) para preeclampsia a menos de 37 semanas y de 0.807 (0.762; 0.852) para preeclampsia global. CONCLUSIONES: La calculadora FMF 4.0 adaptada a población mexicana resultó válida. Si bien tuvo menor rendimiento al esperado para preeclampsia a menos de 37 semanas, el rendimiento para preeclampsia global fue satisfactorio. Se justifica desarrollar la calculadora local.
Abstract OBJECTIVE: To validate the performance of the Fetal Medicine Foundation 4.0 calculator adapted to the Mexican population. MATERIALS AND METHODS: Cohort study performed in singleton pregnancies, according to the competing risk model for preeclampsia in a fetal medicine center in Mexico City. The a priori risk was calculated according to the clinical history. Mean arterial pressure, mean uterine artery pulsatility index and pregnancy-associated plasma protein A were measured at 11 to 14 weeks of gestation with standardized methodology. The value of each marker was transformed into multiples of the median adapted to the local population. Multivariate normal distribution and Bayes' theorem were applied to obtain individual posttest probabilities, which were used as classifiers for the area under the receiver-operator characteristic curve. RESULTS: The incidence of preeclampsia was 5.0% (54/1078). The area under the receiver-operator characteristic curve was 0.784 (0.712; 0.856) for preeclampsia at less than 37 weeks and 0.807 (0.762; 0.852) for global preeclampsia. CONCLUSIONS: The FMF 4.0 calculator adapted to Mexican population proved valid. Although it had lower performance than expected for preeclampsia at less than 37 weeks, the performance for global preeclampsia was satisfactory. The development of the local calculator is justified.
RESUMO
Resumen OBJETIVO: Determinar las diferencias morfológicas macro y microscópicas en las placentas de pacientes con preeclampsia o restricción del crecimiento intrauterino con las de pacientes sanas. MATERIALES Y MÉTODOS: Estudio de casos y controles, retrospectivo, observacional y comparativo. Se revisaron las bases de datos del servicio de Medicina Materno Fetal del Instituto Nacional de Perinatología (INPer) de febrero de 2018 a marzo de 2020 en busca de pacientes con embarazo único y diagnóstico de preeclampsia temprana o restricción del crecimiento temprano y finalización del embarazo en el INPer. El análisis de los datos se llevó a cabo en el programa estadístico SPSS versión 25. Las variables categóricas se compararon entre grupos con χ2 y los resultados se representaron en porcentajes. Para la evaluación estadística analítica se utilizó ANOVA para una muestra independiente para contrastar las asociaciones entre las diversas variables. RESULTADOS: Se incluyeron 52 pacientes que se dividieron en: grupo 1: preeclampsia temprana sin restricción del crecimiento intrauterino (n = 13), grupo 2: preeclampsia y restricción del crecimiento intrauterino temprano (n = 13), grupo 3: restricción del crecimiento intrauterino temprano (n = 13) y grupo 4 (control) pacientes sanas (n = 13). Se demostró una diferencia estadísticamente significativa en el peso de la placenta, con un valor de p < 0.05 pero sin diferencia en el diámetro del cordón umbilical entre los cuatro grupos. CONCLUSIONES: El estudio histopatológico placentario es una oportunidad para obtener información detallada de la base fisiopatológica de la enfermedad y, así, ofrecer una asesoría y seguimiento preciso a la paciente y al neonato.
Abstract OBJECTIVE: To determine the macro and microscopic morphologic differences in placentas of patients with preeclampsia or intrauterine growth restriction with those of healthy patients. MATERIALS AND METHODS: A retrospective, observational and comparative case-control study. The databases of the Maternal Fetal Medicine service of the National Institute of Perinatology (INPer) from February 2018 to March 2020 were reviewed for patients with singleton pregnancy and diagnosis of early preeclampsia or early growth restriction and termination of pregnancy at the INPer. Data analysis was performed in the statistical program SPSS version 25. Categorical variables were compared between groups with χ2 and the results were represented in percentages. For the analytical statistical evaluation, ANOVA for an independent sample was used to contrast the associations between the various variables. RESULTS: Fifty-two patients were included and divided into: group 1: early preeclampsia without intrauterine growth restriction (n = 13), group 2: preeclampsia and early intrauterine growth restriction (n = 13), group 3: early intrauterine growth restriction (n = 13) and group 4 (control) healthy patients (n = 13). A statistically significant difference in placental weight was demonstrated, with a p value < 0.05 but no difference in umbilical cord diameter among the four groups. CONCLUSIONS: Placental histopathologic study is an opportunity to obtain detailed information on the pathophysiologic basis of the disease and thus provide accurate counseling and follow-up to the patient and neonate.
RESUMO
Abstract Pretermbirth is amajormaternal complication that has a great impact on perinatal and neonatal health, with consequences suffered during childhood and adulthood. Little is known about its etiology and development, resulting in poor screening, prediction and preventive methods. The present integrative review discusses the current knowledge regarding some risk factors for preterm birth, the differences between screening and prediction methods, the limitations of some current preventive interventions, the importance of applying standardized concepts for exposures and outcomes, and why it is important to develop more accurate and reproducible methods to predict preterm birth. In addition, the authors introduce the concept of metabolomics and the technology involved in this technique, and discuss about how it has become a promising approach to identify biomarkers for spontaneous preterm birth.
Resumo Parto prematuro é uma complicação obstétrica de grande impacto para saúde perinatal e neonatal, tendo consequências tambémpara a infância e a vida adulta. Pouco se sabe sobre sua etiologia e fatores determinantes, o que limita osmétodos de rastreamento, predição e prevenção. Esta revisão integrativa traz a discussão sobre o conhecimento atual sobre fatores de risco para parto prematuro espontâneo, as diferenças entre métodos de rastreamento e predição, as limitações das atuais intervenções preventivas, a importância de se aplicar conceitos padronizados para exposição e desfecho na investigação de parto prematuro espontâneo, e porque é importante desenvolver métodos precisos e reprodutíveis para predizer o parto prematuro. Por fim, introduzimos o conceito demetabolômica e da tecnologia envolvida nessa técnica, e discutimos como ela tem se mostrado uma abordagem prosmissora para identificar biomarcadores associados ao parto prematuro espontâneo.
