    Abstract

    Objective

    To analyze the scientific production regarding maternal folic acid (FA) supplementation and its relationship with autistic spectrum disorder (ASD).

    Data Sources

    We performed unrestricted electronic searches in the BIREME virtual bank, Virtual Health Library (VHL) and Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed) databases.

    Selection of Studies

    For sample selection, articles that met the proposed objectives were included, published in English, Spanish and Portuguese, the use of Health Sciences Descriptors (DeCS): autistic OR autism AND autism spectrum disorder AND folic acid, AND, with the use of the Medical Subject Headings (MeSH): autistic OR autism AND autistic spectrum disorder AND folic acid.

    Data Collection

    Data extraction was performed by the reviewers with a preestablished data collection formulary.

    Data Synthesis

    The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) was used based on a checklist with 27 items and a 4-step flowchart.

    Results

    A total of 384 articles was found by the search strategies, of which 17 were eligible following the pre-established criteria. The main findings of the present review point to maternal FA supplementation in the pre-conception period and beginning of pregnancy as a protective effect in relation to ASD, which should be indicated in this period as prevention to the problem.

    Conclusion

    According to the research analyzed, more studies are necessary to know its effects on pregnancy, since the consumption of excessive FA may not be innocuous.

    Abstract

    Objective

    To review the evidence about universal iron supplementation in pregnancy to prevent maternal anemia.

    Methods

    Bibliographic research of randomized and controlled clinical trials, meta-analyses, systematic reviews, and clinical guidelines, published between August 2009 and August 2019, using the MeSH terms: iron; therapeutic use; pregnancy; anemia, prevention and control.

    Results

    We included six clinical guidelines, three meta-analyses and one randomized controlled clinical trial.

    Discussion

    Most articles point to the improvement of hematological parameters and reduction of maternal anemia risk, with supplementary iron. However, they do not correlate this improvement in pregnant women without previous anemia with the eventual improvement of clinical parameters.

    Conclusion

    Universal iron supplementation in pregnancy is controversial, so we attribute a SORT C recommendation strength.

    Abstract

    Objective

    To evaluate the effects of vitamin D supplementation in the postpartum period of women with previous gestational diabetes mellitus (GDM).

    Methods

    Randomized clinical trials of pregnant women with GDM of any chronological, gestational age and parity, with no history of previous disease who received vitamin D supplementation in the prenatal and/or postpartum period and were evaluated in the postpartum period were included. The PubMed, EMBASE, Cochrane, and LILACS databases were consulted until July 2019. Serum vitamin D concentration (25- hydroxyvitamin D in nmol/L), fasting blood glucose, glycated hemoglobin, serum calcium concentration, homeostatic model assessment of insulin resistance (HOMAIR), quantitative insulin sensitivity check index (QUICKI), parathyroid hormone (PTH) and body mass index (BMI) were evaluated. Similar results in at least two trials were plotted using the RevMan 5; Cochrane Collaboration, Oxford, Reino Unido. The quality of the evidence was generated according to the classification, development, and evaluation of the classification of the recommendations.

    Results

    Four studies were included in the present review (200 women). The findings indicate that there is no difference in the postpartum period in women diagnosed with previous GDM who received vitamin D supplementation in the prenatal and/or in the postpartum period, showing only that there was a significant increase in the concentration of vitamin D (relative risk [RR]: 1.85; 95% confidence interval [CI]: 1.02-2.68).

    Conclusion

    This increase in the concentration of vitamin D should be interpreted with caution, since the assessment of the quality of the evidence was very low. For the other analyzed outcomes, there was no significance between the intervention and control groups, and the outcomes, when analyzed in their strength of evidence, were considered very low and low in their evaluation.

    Abstract

    Objective

    To compare the effects of expectant versus interventionist care in the management of pregnant women with severe preeclampsia remote from term.

    Data sources

    An electronic search was conducted in the Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database (EMBASE), Cochrane Central Register of Controlled Trials (CENTRAL), Latin American and Caribbean Health Sciences Literature (LILACS, for its Spanish acronym), World Health Organization’s International Clinical Trials Registry Platform (WHO-ICTRP), and Open- Grey databases. The International Federation of Gynecology and Obstetrics (FIGO, for its French acronym), Royal College of Obstetricians and Gynaecologists (RCOG), American College of Obstetricians and Gynecologists (ACOG), and Colombian Journal of Obstetrics and Gynecology (CJOG) websites were searched for conference proceedings, without language restrictions, up to March 25, 2020.

    Selection of studies

    Randomized clinical trials (RCTs), and non-randomized controlled studies (NRSs) were included. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of the evidence.

    Data collection

    Studies were independently assessed for inclusion criteria, data extraction, and risk of bias. Disagreements were resolved by consensus.

    Data synthesis

    Four RCTs and six NRS were included. Low-quality evidence from the RCTs showed that expectant care may result in a lower incidence of appearance, pulse, grimace, activity, and respiration (Apgar) scores<7 at 5 minutes (risk ratio [RR]: 0.48; 95% confidence interval [95%CI]: 0.23%to 0.99) and a higher average birth weight (mean difference [MD]: 254.7 g; 95%CI: 98.5 g to 410.9 g). Very low quality evidence from the NRSs suggested that expectant care might decrease the rates of neonatal death (RR: 0.42; 95%CI 0.22 to 0.80), hyalinemembrane disease (RR: 0.59; 95%CI: 0.40 to 0.87), and admission to neonatal care (RR: 0.73; 95%CI: 0.54 to 0.99). Nomaternal or fetal differences were found for other perinatal outcomes.

    Conclusion

    Compared with interventionist management, expectant care may improve neonatal outcomes without increasing maternal morbidity and mortality.

    Abstract

    Fetal growth restriction (FGR) occurswhen the fetus does not reach its intrauterine potential for growth and development as a result of compromise in placental function. It is a condition that affects 5 to 10% of pregnancies and is the second most common cause of perinatal morbidity and mortality. Children born with FGR are at risk of impaired neurological and cognitive development and cardiovascular or endocrine diseases in adulthood. The purpose of the present revision is to perform a literature search for evidence on the detection and assessment by ultrasound of brain injury linked to FGR during fetal life. Using a systematic approach and quantitative evaluation as study methodology, we reviewed ultrasound studies of the fetal brain structure of growth-restricted fetuses with objective quality measures. A total of eight studies were identified. High quality studies were identified for measurement of brain volumes; corpus callosum; brain fissure depth measurements, and cavum septi pellucidi width measurement. A low-quality study was available for transverse cerebellar diameter measurement in FGR. Further prospective randomized studies are needed to understand the changes that occur in the brain of fetuseswith restricted growth, as well as their correlation with the changes in cognitive development observed.

    Abstract

    Introduction

    Preeclampsia (PE) is a pregnancy complication associated with increased maternal and perinatal morbidity and mortality. The disease presents with recent onset hypertension (after 20 weeks of gestation) and proteinuria, and can progress to multiple organ dysfunction, with worse outcomes among early onset preeclampsia (EOP) cases (<34 weeks). The placenta is considered the root cause of PE; it represents the interface between the mother and the fetus, and acts as a macromembrane between the two circulations, due to its villous and vascular structures. Therefore, in pathological conditions, macroscopic and microscopic evaluation can provide clinically useful information that can confirm diagnosis and enlighten about outcomes and future therapeutic benefit.

    Objective

    To perform an integrative review of the literature on pathological placental findings associated to preeclampsia (comparing EOP and late onset preeclampsia [LOP]) and its impacts on clinical manifestations.

    Results:

    Cases of EOP presented worse maternal and perinatal outcomes, and pathophysiological and anatomopathological findings were different between EOP and LOP placentas, with less placental perfusion, greater placental pathological changes with less villous volume (villous hypoplasia), greater amount of trophoblastic debris, syncytial nodules, microcalcification, villous infarcts, decidual arteriolopathy in EOP placentas when compared with LOP placentas. Clinically, the use of low doses of aspirin has been shown to be effective in preventing PE, as well asmagnesium sulfate in preventing seizures in cases of severe features.

    Conclusion

    The anatomopathological characteristics between EOP and LOP are significantly different, with large morphological changes in cases of EOP, such as

    Abstract

    Objective

    Coronavirus disease 2019 (COVID-19) is a disease caused by a newly discovered coronavirus, severe acute respiratory syndrome coronavirus 2 (SARSCoV-2), which usually leads to non-specific respiratory symptoms. Although pregnant women are considered at risk for respiratory infections by other viruses, such as SARS and Middle East respiratory syndrome (MERS), little is known about their vulnerability to SARS-CoV-2. Therefore, this study aims to identify and present the main studies on the topic, including the postpartum period.

    Methods

    In this narrative review, articles were searched in various databases, organizations, and health entities using keywords compatible with medical subject headings (MeSH), such as: COVID-19, pregnancy, vertical transmission, coronavirus 2019, and SARS-CoV-2.

    Results

    The review of the scientific literature on the subject revealed that pregnant women with COVID-19 did not present clinical manifestations significantly different from those of non-pregnant women; however, there are contraindicated therapies. Regarding fetuses, studies were identified that reported that infection by SARS-CoV-2 in pregnant women can cause fetal distress, breathing difficulties and premature birth, but there is no substantial evidence of vertical transmission.

    Conclusion

    Due to the lack of adequate information and the limitations of the analyzed studies, it is necessary to provide detailed clinical data on pregnant women infected with SARS-CoV-2 and on the maternal-fetal repercussions caused by this infection. Thus, this review may contribute to expand the knowledge of professionals working in the area as well as to guide more advanced studies on the risk related to pregnant women and their newborns. Meanwhile, monitoring of confirmed or suspected pregnant women with COVID-19 is essential, including in the postpartum period.

    Abstract

    In a healthy athlete, the caloric intake is sufficient for sports energy needs and body physiological functions, allowing a balance between energy availability, bone metabolism, andmenstrual cycle.Onthe other hand, an imbalance causedby low energy availability dueto a restrictive diet, eating disorders or long periods of energy expenditure leads to multisystemic deregulation favoring the essential functions of the body. This phenomenon, described as the female athlete triad, occurs in a considerable percentage of high-performance athletes, with harmful consequences for their future. The present review was carried out based on a critical analysis of themost recent publications available and aims to provide a global perception of the topic relative energy deficit in sport (RED-S). The objective is to promote theacquisition ofmore consolidated knowledgeon an undervaluedtheme, enabling the acquisition of preventive strategies, early diagnosis and/or appropriate treatment.
