RESUMO
Background: We aimed to conduct a systematic review and meta-analysis to evaluate the fetoscopic tracheal occlusion in patients with isolated severe and left-sided diaphragmatic hernia. Methods: Cochrane Library, Embase, and PubMed (Medline) databases were searched from inception to February 2024 with no filters or language restrictions. We included studies evaluating the outcomes of fetoscopic intervention compared to expectant management among patients with severe congenital diaphragmatic hernia exclusively on the left side. A random-effects pairwise meta-analysis was performed using RStudio version 4.3.1. Results: In this study, we included 540 patients from three randomized trials and five cohorts. We found an increased likelihood of neonatal survival associated with fetoscopic tracheal occlusion (Odds Ratio, 5.07; 95% Confidence Intervals, 1.91 to 13.44; p < 0.01) across general and subgroup analyses. Nevertheless, there were higher rates of preterm birth (OR, 5.62; 95% CI, 3.47-9.11; p < 0.01) and preterm premature rupture of membranes (OR, 7.13; 95% CI, 3.76-13.54; p < 0.01) in fetal endoscopic tracheal occlusion group compared to the expectant management. Conclusions: Our systematic review and meta-analysis demonstrated the benefit of fetoscopic tracheal occlusion in improving neonatal and six-month postnatal survival in fetuses with severe left-sided CDH. Further studies are still necessary to evaluate the efficacy of tracheal occlusion for isolated right-sided CDH, as well as the optimal timing to perform the intervention.
RESUMO
OBJECTIVES: We aimed to perform a systematic review and network meta-analysis to evaluate the preventive strategies for preterm birth in twin-to-twin transfusion syndrome. METHODS: PubMed, Embase and Cochrane Central were searched from inception to December 2023 with no filters. Additionally, the reference lists of the included studies were manually examined to identify any supplementary studies. We selected randomized controlled trials and cohorts comparing interventions to prevent preterm birth in twin pregnancies complicated by twin-to-twin transfusion syndrome. A random-effects frequentist network meta-analysis was performed using RStudio version 4.3.1. Randomized controlled trials and cohorts were assessed respectively using the Risk of Bias in Non-randomized Studies of interventions tool and Cochrane Collaboration's tool for assessing risk of bias in randomized trials. RESULTS: In this systematic review and meta-analysis, we included eight studies comprising a total of 719 patients. Compared with expectant management, cerclage stood out as the only intervention associated with an increase in the survival of at least one twin (risk ratio 1.12; 95â¯% confidence interval 1.01-1.23). Our subgroup analysis based on different thresholds for short cervix demonstrated a significant reduction in the risk of preterm birth before 32 weeks with ultrasound-indicated cerclage using a 15â¯mm criterion (risk ratio 0.65; 95â¯% confidence interval 0.47-0.92). CONCLUSIONS: Our study suggests the potential benefit of cerclage as a preventive strategy for preterm birth in pregnancies complicated by twin-to-twin transfusion syndrome. These findings highlight the necessity for further investigation to corroborate our results and address the optimal threshold for ultrasound-indicated cerclage.

OBJECTIVE: To assess the impact of overweight and obesity in the second and third trimesters of pregnancy on fetal cardiac function parameters. METHODS: We performed a prospective cohort study of 374 singleton pregnant women between 20w0d and 36w6d divided into three groups: 154 controls (body mass index - BMI < 25 kg/m2), 140 overweight (BMI 25-30 kg/m2) and 80 obese (BMI ≥ 30 kg/m2). Fetal left ventricular (LV) modified myocardial performance index (Mod-MPI) was calculated according to the following formula: (isovolumetric contraction time + isovolumetric relaxation time)/ejection time. Spectral tissue Doppler was used to determine LV and right ventricular (RV) myocardial performance index (MPI'), peak myocardial velocity during systole (S'), early diastole (E'), and late diastole (A'). RESULTS: We found significant differences between the groups in maternal age (p < 0.001), maternal weight (p < 0.001), BMI (p < 0.001), number of pregnancies (p < 0.001), parity (p < 0.001), gestational age (p = 0.013), and estimated fetal weight (p = 0.003). Overweight pregnant women had higher LV Mod-MPI (0.046 versus 0.044 seconds, p = 0.009) and LV MPI' (0.50 versus 0.47 seconds, p < 0.001) than the control group. Obese pregnant women had higher RV E' than control (6.82 versus 6.33 cm/sec, p = 0.008) and overweight (6.82 versus 6.46 cm/sec, p = 0.047) groups. There were no differences in 5-min APGAR score < 7, neonatal intensive care unit admission, hypoglycemia and hyperglobulinemia between the groups. CONCLUSIONS: We observed fetal myocardial dysfunction in overweight and obese pregnant women with higher LV Mod-MPI, LV MPI' and RV E' compared to fetuses from normal weight pregnant women.

OBJECTIVE: Gastroschisis (GS) is a congenital anomaly in the abdominal wall with the intestinal loops exiting laterally to the umbilicus. The contact of the loops with Amniotic Fluid (AF) causes an inflammatory process in the exposed part, leading to an extended hospital stay and an increased risk of morbidity due to alterations related to intestinal motility. The authors aimed to evaluate the time of exposure to the AF in the experimental GS and to search for potential biomarkers of intestinal inflammation by measuring microRNAs. METHODS: Rat fetuses were divided into three groups: a) CONTROL, b) GS reared on day 18 (GS = 18), and c) GS reared on day 19.5 (GS = 19) (term = 22 days). On day 21.5, the fetuses were removed for biometric parameters and biochemical analyses: 1) Biometrics: Body and Intestinal Weight (BW, IW), and intestinal-body weight ratio (IW/BW); 2) Descriptive histopathology and 3) miR-143 quantification by real-time Polymerase Chain Reaction (PCR). RESULTS: BW was higher in CONTROL than GS 18 and G19 (p < 0.05). IW, IW/BW, intestinal water, and mRNA-143 were higher in GS 18 and GS 19 than in CONTROL, and GS 18 was higher than GS 19 (p < 0.05). The average of the inflammation score from the intestinal wall with mucosal inflammation and intra-epithelial lymphocytes shows worst in GS 18 and GS 19 vs. CONTROL (p < 0.05). CONCLUSIONS: The tissue expression of mRNA-143 and the morphological changes in the intestine of GS worsened according to the time of exposure to AF, which could be a possible marker of fetal intestinal damage.

OBJECTIVE: To estimate the prevalence of unplanned pregnancy in eight public university hospitals, distributed in the five regions that make up Brazil. METHODS: A secondary analysis of a national multicenter cross-sectional study, carried out in eight public university hospitals between June 1 and August 31, 2020, in Brazil. Convenience sample including women who gave birth within sixty consecutive days and met the following criteria: over 18 years old; gestational age over 36 weeks at delivery; with a single and live newborn, without malformations. RESULTS: Sample composed of 1,120 postpartum women, of whom 756 (67.5%) declared that the pregnancy had not been planned. The median prevalence of unplanned pregnancy was 59.7%. The prevalence of unplanned pregnancy across hospitals differed significantly: Campinas (54.8%), Porto Alegre (58.2%), Florianópolis (59%), Teresina (61.2%), Brasília (64.3%), São Paulo (64.6%), Campo Grande (73.9%) and Manaus (95.3%) (p < 0.001). Factors significantly associated with unplanned pregnancy were maternal age, black color, lower family income, greater number of children, greater number of people living in household, and not having a partner. CONCLUSION: In the studied sample, about two thirds of the pregnancies were declared as unplanned. The prevalence of unplanned pregnancies was related to social and demographic factors and varied significantly across the university hospitals evaluated.

OBJECTIVE: To describe the ultrasonographic characteristics of congenital porto-systemic venous shunts (CPSS) diagnosed during pregnancy, their outcomes, and their evolution. METHODS: Two independent researchers selected 493 review articles and case reports through the analysis of titles, abstracts, and full text. The PubMed and LILACS databases were searched. Through the application of filters according to the PRISMA protocol, only six articles were used in the research. The following information was collected, when available: gestational age at diagnosis, gender, birth weight, type of shunt, associated anomalies/complications and treatment/progression. RESULTS: The data were obtained from 27 cases, with 22 (82%) fetuses diagnosed with intra-hepatic CPSS and 5 (18%) with extra-hepatic CPSS. The median time of intrauterine diagnosis was 33 weeks. In 12 (57.1%) of the 21 pregnancies evaluated, delivery was preterm. The estimated fetal weight ranged from 1150 to 3760 g, with 4 (25%) cases at <3rd, 3 (18.75%) cases at <10th, 8 (50%) cases at <50th, and 1 (6.25%) case at >97th percentile for gestational age. The most frequent obstetric complication was fetal growth restriction, which occurred in nine (60%) cases. As for postnatal treatment, 19 (70.4%) cases were conservatively treated, and 8 (29.6%) cases required surgical intervention. CONCLUSION: The diagnosis of CPSS still represents a challenge during prenatal care. Its early identification aims to provide guidance to pregnant women and their families, as well as follow-up and anticipation of possible complications, in addition to the evaluation of the mode of delivery and postnatal follow-up, directing the short- and long-term prognosis.

Background: Congenital diaphragmatic hernia (CDH) is a severe embryological defect that causes pulmonary hypoplasia and hypertension. The prevalence and mortality rate of CDH varies around the world and little information is available about CDH in Latin America. Our aim was to estimate the general prevalence, mortality rate, prevalence of associated anomalies and features related to the outcomes of CDH in newborns from São Paulo state, Brazil. Methods: Population-based cross-sectional study based on data gathered from the Live Births Information System (SINASC) and the Mortality Information System (SIM) of children born in São Paulo state between January 1st, 2006, and December 31st, 2017. Findings: From 7,311,074 total survival discharges between 2006 and 2017, 1,155 were CDH-related, resulting in a prevalence rate of 1:6329 (95%CI = 1/6715 - 1/5984) and a mortality rate of 63·72% (95%CI = 60.95 - 66.50), 510 presented complex associated anomalies (44·15%). Maternal data showed higher prevalence among older mothers (older than 35 years old: 2·13 per 10,000) and, also, women with more years of schooling (higher than 12 years: 1·99 per 10,000). Presence of associated anomalies (95%CI = 5.69-11.10), 1-min Apgar (95%CI = 1.44-2.95), maternal schooling (95%CI = 1.06-2.43) and birth weight (95%CI = 1.04-2.26) were the most significant features associated with mortality. Interpretation: There was 1 CDH case for every 6329 newborns in São Paulo and the mortality rate among those cases was 63·72% - a high rate compared to other countries. Funding: This study didn't receive any specific grant from any funding agency in the public, commercial or not-for-profit sectors.
RESUMO
OBJECTIVE: To identify people with history of mental health disorders before the COVID-19 pandemic in the Brazilian population and estimate the prevalence of mood swings and the subjective distress of the pandemic among individuals with or without mental health disorders. METHODS: Through an online survey, participants were asked about presence or absence of mental health disorders. In addition, they answered the Brunel Mood Scale and the Impact of Event Scale. The mean percentile of mood swing indicators and psychological impact scores were estimated, and data were analyzed by logistic regression. RESULTS: 13,248 people participated (70.5% women, mean age 35.4 years, 31.2% with history of mental health disorder). Women and younger people were more likely to be diagnosed with mental health disorder. All participants had significant changes in mood due to the pandemic. Anger, depressed mood, mental confusion, and fatigue were higher among individuals with bipolar disorder or with combined disorders. Individuals with mental health disorders had a greater subjective distress, especially the group with bipolar disorder (OR = 4.89 [3.64-6.56]) and combined disorders (OR = 6.89 [5.21-9.10]). CONCLUSION: Individuals previously diagnosed with mental health disorders at some point in life are more vulnerable to psychological impact from the pandemic.

OBJECTIVES: The present systematic review aims to investigate the diagnosis, prognosis, delivery assistance, pregnancy results and postnatal management in gastroschisis. STUDY DESIGN: The following data sources were evaluated: The CINAHL, Embase and MEDLINE/PubMed databases were searched, observational and intervention studies published over the past 20 years. The quality of the studies was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). RESULTS: A total of 3770 infants diagnosed with gastroschisis were included (44 studies); 1534 fetuses were classified as simple gastroschisis and 288 as complex gastroschisis. Intrauterine fetal demise occurred in 0.47% and elective termination occurred in 0.13%. Preterm delivery occurred in 23.23% and intrauterine growth restriction in 4.43%. Cesarean section delivery was performed in 54.6%. Neonatal survival was 91.29%. The main neonatal complications were: sepsis (11.78%), necrotizing enterocolitis (2.33%), short bowel syndrome (1.37%), bowel obstruction (0.79%), and volvulus (0.23%). Immediate surgical repair was performed in 80.1% with primary closure in 69%. The average to oral feeding was 33 (range: 11-124.5) days. Average hospital duration was 38 days and 89 days in neonates with simple and complex grastroschisis, respectively. CONCLUSIONS: The present systematic review provides scientific data for counseling families with fetal gastroschisis.

OBJECTIVE: To study maternal anxiety in pregnant women without comorbidities in the context of the COVID-19 outbreak in Brazil and to study maternal knowledge and concerns about the pandemic. METHODS: This is a secondary analysis from a national multicenter cross-sectional study performed in 10 cities, from June to August, 2020, in Brazil. Interviewed postpartum women, without medical or obstetrical comorbidities, were included in the present subanalysis. A structured questionnaire and the Beck Anxiety Inventory (BAI) were applied. RESULTS: Out of the 1,662 women, 763 (45.9%) met the criteria for the current analysis and 16.1% presented with moderate and 11.5% with severe maternal anxiety. Moderate or severe maternal anxiety was associated with high school education (odds ratio [OR]:1.58; 95% confidence interval [CI]:1.04-2.40). The protective factor was cohabiting with a partner (OR: 0.46; 95%CI: 0.29-0.73). There was a positive correlation between the total BAI score and receiving information about care in the pandemic (rpartial 0.15; p < 0.001); concern about vertical transmission of COVID-19 (rpartial 0.10; p = 0.01); receiving information about breastfeeding (rpartial 0.08; p = 0.03); concerns about prenatal care (rpartial 0.10; p = 0.01), and concerns about the baby contracting COVID-19 (rpartial 0.11; p = 0.004). The correlation was negative in the following aspects: self-confidence in protecting from COVID-19 (rpartial 0.08; p = 0.04), having learned (rpartial 0.09; p = 0.01) and self-confidence in breastfeeding (rpartial 0.22; p < 0.001) in the context of the pandemic. CONCLUSION: The anxiety of pregnant women without medical or obstetrical comorbidities was associated to high school educational level and not living with a partner during the COVID-19 pandemic. Self-confidence in protecting against COVID-19 and knowledge about breastfeeding care during the pandemic reduced maternal anxiety.

MéTODOS: Trata-se de análise secundária de um estudo transversal multicêntrico nacional realizado em 10 cidades, de junho a agosto de 2020, no Brasil. Mulheres no pós-parto entrevistadas, sem comorbidades médicas ou obstétricas, foram incluídas nesta subanálise. Foram aplicados um questionário estruturado e o Inventário de Ansiedade de Beck (BAI, na sigla em inglês). RESULTADOS: Das 1.662 mulheres, 763 (45,9%) atenderam aos critérios da análise atual e 16,1% apresentaram ansiedade materna moderada e 11,5% ansiedade materna grave. A ansiedade materna moderada ou grave foi associada à escolaridade no ensino médio (odds ratio [OR]: 1,58; intervalo de confiança [IC] 95%: 1,042,40). O fator protetor foi coabitar com companheiro (OR: 0,46; IC95%: 0,290,73). Houve correlação positiva entre a pontuação total do BAI e o recebimento de informações sobre cuidados na pandemia (rparcial 0,15; p < 0,001); preocupação com a transmissão vertical de COVID-19 (rparcial 0,10; p = 0,01); receber informações sobre amamentação (rparcial 0,08; p = 0,03); preocupações sobre cuidados pré-natais (rparcial 0,10; p = 0,01) e preocupações sobre o bebê contrair COVID-19 (rparcial 0,11; p = 0,004). A correlação foi negativa com os seguintes aspectos: ter autoconfiança para se proteger (rparcial 0,08; p = 0,04), aprender (rparcial 0,09; p = 0,01) e ter autoconfiança para amamentar (rparcial 0,22; p < 0,001) no contexto da pandemia. CONCLUSãO: A ansiedade de gestantes sem comorbidades médicas ou obstétricas esteve associada à escolaridade no ensino médio e não morar com companheiro durante a pandemia de COVID-19. A autoconfiança na proteção contra COVID-19 e o conhecimento sobre os cuidados com a amamentação durante a pandemia reduziram a ansiedade materna.

Although gastroschisis is often diagnosed by prenatal ultrasound, there is still a gap in the literature about which prenatal ultrasound markers can predict complex gastroschisis. This systematic review and meta-analysis aimed to investigate the ultrasound markers that characterize complex gastroschisis. A systematic review of the literature was conducted according to the guidelines of PRISMA. The protocol was registered (PROSPERO ID CRD42020211685). Meta-analysis was displayed graphically on Forest plots, which estimate prevalence rates and risk ratios, with 95% confidence intervals, using STATA version 15.0. The combined prevalence of intestinal complications in fetuses with complex gastroschisis was 27.0%, with a higher prevalence of atresia (about 48%), followed by necrosis (about 25%). The prevalence of deaths in newborns with complex gastroschisis was 15.0%. The predictive ultrasound markers for complex gastroschisis were intraabdominal bowel dilatation (IABD) (RR 3.01, 95% CI 2.22 to 4.07; I2 = 15.7%), extra-abdominal bowel dilatation (EABD) (RR 1.55, 95% CI 1.01 to 2.39; I2 = 77.1%), and polyhydramnios (RR 3.81, 95% CI 2.09 to 6.95; I2 = 0.0%). This review identified that IABD, EABD, and polyhydramnios were considered predictive ultrasound markers for complex gastroschisis. However, evidence regarding gestational age at the time of diagnosis is needed.
RESUMO
Background: Patients with congenital diaphragmatic hernia (CDH) have a short postnatal period of ventilatory stability called the honeymoon period, after which changes in pulmonary vascular reactivity result in pulmonary hypertension. However, the mechanisms involved are still unknown. The aim of this study was to evaluate mechanical ventilation's effect in the honeymoon period on VEGF, VEGFR-1/2 and eNOS expression on experimental CDH in rats. Materials and Methods: Neonates whose mothers were not exposed to nitrofen formed the control groups (C) and neonates with left-sided defects formed the CDH groups (CDH). Both were subdivided into non-ventilated and ventilated for 30, 60, and 90 min (n = 7 each). The left lungs (n = 4) were evaluated by immunohistochemistry of the pulmonary vasculature (media wall thickness), VEGF, VEGFR-1/2 and eNOS. Western blotting (n = 3) was performed to quantify the expression of VEGF, VEGFR-1/2 and eNOS. Results: CDH had lower biometric parameters than C. Regarding the pulmonary vasculature, C showed a reduction in media wall thickness with ventilation, while CDH presented reduction with 30 min and an increase with the progression of the ventilatory time (honeymoon period). CDH and C groups showed different patterns of VEGF, VEGFR-1/2 and eNOS expressions. The receptors and eNOS findings were significant by immunohistochemistry but not by western blotting, while VEGF was significant by western blotting but not by immunohistochemistry. Conclusion: VEGF, its receptors and eNOS were altered in CDH after mechanical ventilation. These results suggest that the VEGF-NO pathway plays an important role in the honeymoon period of experimental CDH.
RESUMO
Myelomeningocele (MMC), the commonest type of spina bifida (SB), occurs due to abnormal development of the neural tube and manifest as failure of the complete fusion of posterior arches of the spinal column, leading to dysplastic growth of the spinal cord and meninges. It is associated with several degrees of motor and sensory deficits below the level of the lesion, as well as skeletal deformities, bladder and bowel incontinence, and sexual dysfunction. These children might develop varying degrees of neuropsychomotor delay, partly due to the severity of the injuries that affect the nervous system before birth, partly due to the related cerebral malformations (notably hydrocephalus-which may also lead to an increase in intracranial pressure-and Chiari II deformity). Traditionally, MMC was repaired surgically just after birth; however, intrauterine correction of MMC has been shown to have several potential benefits, including better sensorimotor outcomes (since exposure to amniotic fluid and its consequent deleterious effects is shortened) and reduced rates of hydrocephalus, among others. Fetal surgery for myelomeningocele, nevertheless, would not have been made possible without the development of experimental models of this pathological condition. Hence, the aim of the current article is to provide an overview of the animal models of MMC that were used over the years and describe how this knowledge has been translated into the fetal treatment of MMC in humans.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic may have an effect on maternal anxiety and influence postpartum experience. OBJECTIVE: To study the prevalence of maternal anxiety in late pregnancy in the context of the COVID-19 outbreak in Brazil and to analyze its association with maternal knowledge and concerns about the pandemic. METHODS: This was a national multicenter cross-sectional study performed in 10 different public university hospitals, between 1 June and 31 August 2020, in Brazil. The inclusion criteria were: maternal age more than 18 years; gestational age more than 36 weeks at childbirth; single alive newborn without malformations; and absence of mental disorders. We applied a structured questionnaire to explore the knowledge and concerns about COVID-19. Maternal anxiety was assessed using the Beck Anxiety Inventory (BAI). RESULTS: Of the 1662 women interviewed, the BAI score in late pregnancy indicated that 13.9% presented moderate and 9.6% severe maternal anxiety. Moderate or severe maternal anxiety was independently associated with the fear of being unaccompanied at childbirth (aOR1.12, 95% CI 1.10-1.35), and independent protective factors were confidence in knowing how to protect oneself from COVID-19 (aOR0.89, 95% CI 0.82-0.97) and how to safely breastfeed (aOR0.89, 95% CI 0.83-0.95). CONCLUSION: The COVID-19 pandemic has a significant impact on maternal anxiety.
RESUMO
BACKGROUND: Isolation measures used to contain epidemics generate social interaction restrictions and impose changes in routines of the public that increase negative psychological outcomes. Anxiety and depression are the most common symptoms. OBJECTIVE: To evaluate the mental health of the Brazilian population during the SARs-CoV-2 pandemic and its relationship with demographic and health characteristics. METHODS: Adults from all Brazilian States participated (n = 12,196; women: 69.8%, mean age = 35.2 years). The Depression, Anxiety and Stress Scale, and the Impact of Event Scale-revised were used (online survey). Data validity and reliability were verified by confirmatory factor analysis and ordinal alpha coefficient. The probability of presenting psychological symptoms was calculated by multiple logistic regression and odds ratio (OR) (0 = without symptoms, 1 = with mild, moderate, and severe levels of symptoms). RESULTS: High prevalence of depression (61.3%), anxiety (44.2%), stress (50.8%), and psychological impact (54.9%) due to the isolation experienced from the pandemic was found. Younger individuals (OR = 1.58-3.58), those that felt unsafe (OR = 1.75-2.92), with a previous diagnosis of mental health (OR = 1.72-2.64) and/or had general health problems before the pandemic (OR = 1.17-1.51), who noticed changes in their mental state due to the pandemic context (OR = 2.53-9.07), and excessively exposed to the news (OR = 1.19-2.18) were at increased risk of developing symptoms. Women (OR = 1.35-1.65) and those with lower economic status (OR = 1.38-2.69) were more likely to develop psychological symptoms. Lower educational levels increased the likelihood of depressive (OR = 1.03-1.34) and intrusive symptoms (OR = 1.09-1.51). Conclusions: The pandemic and related factors can have a high impact on the mental health of the population. Demographic characteristics can influence the occurrence of psychological symptoms.
RESUMO
OBJECTIVE: The present comprehensive review aims to show the full extent of what is known to date and provide a more thorough view on the effects of SARS-CoV2 in pregnancy. METHODS: Between March 29 and May, 2020, the words COVID-19, SARS-CoV2, COVID-19 and pregnancy, SARS-CoV2 and pregnancy, and SARS and pregnancy were searched in the PubMed and Google Scholar databases; the guidelines from well-known societies and institutions (Royal College of Obstetricians and Gynaecologists [RCOG], American College of Obstetricians and Gynecologists [ACOG], International Society of Ultrasound in Obstetrics & Gynecology [ISUOG], Centers for Disease Control and Prevention [CDC], International Federation of Gynecology and Obstetrics [FIGO]) were also included. CONCLUSION: The COVID-19 outbreak resulted in a pandemic with > 3.3 million cases and 230 thousand deaths until May 2nd. It is caused by the SARS-CoV2 virus and may lead to severe pulmonary infection and multi-organ failure. Past experiences show that unique characteristics in pregnancy make pregnant women more susceptible to complications from viral infections. Yet, this has not been reported with this new virus. There are risk factors that seem to increase morbidity in pregnancy, such as obesity (body mass index [BMI] > 35), asthma and cardiovascular disease. Current reports describe an increased rate of preterm birth and C-section. Vertical transmission is still a possibility, due to a few reported cases of neonatal positive real-time polymerase chain reaction (RT-PCR) in nasal swab, amniotic fluid, and positive immunoglobulin M (IgM) in neonatal blood. Treatments must be weighed in with caution due to the lack of quality trials that prove their effectiveness and safety during pregnancy. Medical staff must use personal protective equipment in handling SARS-CoV2 suspected or positive patients and be alert for respiratory decompensations.
OBJETIVO: A presente revisão detalhada busca fornecer dados objetivos para avaliar o que se sabe até o momento e possibilitar uma visão mais ampla dos efeitos do SARS-CoV2 na gravidez. MéTODOS: Entre 29 de março e 2 de maio de 2020, foi realizada uma busca nos bancos de dados PubMed e Google Scholar com as palavras COVID-19, SARS-CoV2, COVID-19 e gravidez, SARS-CoV2 e gravidez, e SARS e gravidez. As recomendações dos principais órgãos sobre o tema também foram acessadas. CONCLUSãO: O surto de COVID-19 resultou em uma pandemia com > 3.3 milhões de casos e 230 mil mortes até 2 de maio. É uma condição causada pelo vírus SARS-CoV2 e pode levar ao acometimento pulmonar difuso e à falência de múltiplos órgãos. Características únicas da gestante tornam essa população mais propensas a complicações de infecções virais. Até o momento, essa tendência não foi observada para esse novo vírus. Os fatores que parecem estar associados à maior morbidade materno-fetal são obesidade (índice de massa corporal [IMC] > 35), asma e doença cardiovascular. Há descrição de aumento de parto prematuro e parto cesáreo. Não se pode descartar a possibilidade de transmissão vertical da doença, devido a relatos de positividade de reação em cadeia de polimerase (RT-PCR) de swab nasal, RT-PCR de líquido amniótico e imunoglobulina M (IgM) de recém-nascidos. Tratamentos devem ser analisados caso a caso, dada a falta de qualidade de estudos que comprovem a sua eficácia e segurança na gravidez. O corpo clínico deve utilizar equipamentos de proteção individual (EPI) ao manusear pacientes suspeitos ou confirmados e ficar atento aos sinais de descompensação respiratória.

OBJECTIVES: Renal development is impaired in fetal growth restriction (FGR). Renal size can be considered a surrogate of renal function in childhood, and could be impaired in that condition. Our aim was to evaluate the ratio of total renal volume, measured by three-dimensional ultrasound, to estimated fetal weight (TRV/EFW) among fetuses with and without growth restriction. Furthermore, we correlated TRV/EFW with fetal Doppler velocimetry and renal vascularization indexes and evaluated the association of renal volume and vascular parameters with adverse neonatal events in growth-restricted fetuses. METHODS: In a retrospective cohort, TRV and renal vascularization of growth-restricted and normal fetuses were evaluated by three-dimensional ultrasonography and VOCAL technique. Independent samples t-tests and Mann-Whitney test were used for comparisons between groups. Logistic regression model was applied to evaluate the association between renal characteristics and adverse neonatal events. RESULTS: Seventy-one growth-restricted fetuses were compared to 194 controls. The TRV/EFW was lower in the growth-restricted group (P < .001). In our sample, this ratio did not correlate with Doppler velocimetry parameters, renal vascular indexes or any adverse neonatal events. CONCLUSION: The TRV/EFW ratio is decreased in FGR. Further studies are needed to investigate the association of this ratio with long-term renal outcomes.
