Perinatal Results and Long-Term Follow-Up of Fetal Cardiac Tumors: A 30-Year Historical Cohort Study. / Resultados Perinatais e Seguimento em Longo Prazo de Tumores Cardíacos Fetais: Estudo de Coorte Histórica de 30 Anos.

BACKGROUND: This was a 30-year retrospective cohort study that approximates closely to the natural history of cardiac tumors diagnosed in the fetus, since there was no case of pregnancy interruption. OBJECTIVE: To assess morbidity and mortality in the perinatal period and at long term in fetuses diagnosed with cardiac tumor. Our secondary objective was to assess the evaluating factors of perinatal and postnatal results. METHODS: This was a retrospective cohort study with 74 pregnant women with an echocardiographic diagnosis of fetal cardiac tumor at two referral centers between May 1991 and November 2021. A descriptive analysis was performed, and data were expressed as absolute (n) and relative (%) frequencies, median and interquartile range. Fisher's exact test was used to evaluate the association of echocardiographic characteristics and clinical manifestations with perinatal and postnatal results. Global survival was calculated using the Kaplan-Meier method and the curves were compared by the log-rank test. The time of follow-up, calculated in months, corresponded to the time elapsed from hospital discharge to current status (survived/ censoring or death). The level of significance was set at 5% (p<0.05). RESULTS: Rhabdomyoma is the most common type of cardiac tumor (85%), with a high morbidity (79.3%) and overall mortality of 17.4%. The presence of fetal hydrops was a predictor of death. CONCLUSION: The presence of fetal hydrops had an impact on mortality, and hence is an important factor in counselling and determining the prognosis. Most deaths occurred before hospital discharge.

FUNDAMENTO: Seguimento de coorte retrospectiva de 30 anos que se aproxima da história natural dos tumores cardíacos diagnosticados no feto uma vez que nenhum caso foi submetido à interrupção da gestação. OBJETIVO: Avaliar a morbidade e mortalidade perinatal e em longo prazo em fetos com diagnóstico de tumor cardíaco. Como objetivo secundário avaliar os fatores que influenciaram os resultados perinatais e pós-natais. MÉTODO: Estudo de coorte retrospectiva envolvendo 74 gestantes com diagnóstico ecocardiográfico fetal de tumor cardíaco acompanhadas em dois serviços de referência no período de maio de 1991 a novembro de 2021. Foi realizada análise descritiva dos dados por meio de frequências absolutas (n) e relativas (%), mediana e intervalos interquartis. Para avaliar a associação entre as características ecocardiográficas e as manifestações clínicas com os resultados perinatais e pós-natais, foi aplicado o teste exato de Fisher. O cálculo da sobrevida global foi realizado pelo método de Kaplan-Meier e a comparação de curvas pelo teste de log-rank. O tempo de seguimento, calculado em meses, foi definido a partir da data de alta do hospital à data do status atual (vivo/censura ou óbito). O nível de significância considerado foi de 5% (p<0,05). RESULTADOS: o rabdomioma é o tipo mais frequente (85%) de tumor cardíaco; apresenta alta morbidade (79,3%) e mortalidade geral de 17,4%; a presença de hidropisia fetal preditiva de óbito. CONCLUSÃO: A presença de hidropisia fetal teve impacto na mortalidade, sendo fator importante para aconselhamento e estabelecimento de prognóstico. A maioria dos óbitos ocorrem antes da alta hospitalar.

Diet Quality Indices and Physical Activity Levels Associated with Adequacy of Gestational Weight Gain in Pregnant Women with Gestational Diabetes Mellitus.

The aim of this study was to evaluate the Diet Quality Index (DQI) and the Physical Activity (PA) levels associated with adequacy of gestational weight gain in pregnant women with gestational diabetes mellitus (GDM). A total of 172 pregnant women with a single fetus and a diagnosis of GDM participated. Food intake was self-reported on the food frequency questionnaire and DQI was quantified using the index validated and revised for Brazil (DQI-R). To assess PA, the Pregnancy Physical Activity Questionnaire was administered. Gestational weight gain was classified, following the criteria of the Institute of Medicine, into adequate (AWG), insufficient (IWG), or excessive (EWG) weight gain. A multinomial logistic regression analysis was performed, with level of significance <0.05. The participants were divided into 3 groups: AWG (33.1%), IWG (27.3%), and EWG (39.5%). The analysis indicated that if the pregnant women PA fell into tertile 1 or 2, then they had a greater chance of having IWG, whereas those with the lowest scores on the DQI-R, whose PA fell into tertile 2, and pregestational obesity women had the greatest chance of having EWG. This study has shown that low PA levels may contribute towards IWG. On the other hand, a low final DQI-R score, representing inadequate food habits, low PA levels, and pregestational obesity may increase the chance of EWG in patients with GDM.

Influence of the prone position on a stretcher for pregnant women on maternal and fetal hemodynamic parameters and comfort in pregnancy.

OBJECTIVES:: To analyze the influence of lying in prone position on a specially designed stretcher on the maternal-fetal hemodynamic parameters and comfort of pregnant women. METHODS:: A randomized, controlled trial with 33 pregnant women divided into 2 groups: pregnant group sequence 1 and pregnant group sequence 2. The order of positions used in sequence 1 was Fowler's position, prone position, supine position, left lateral, Fowler's position 2, supine position 2, prone position 2 and left lateral 2. The order of positions used in sequence 2 was Fowler's position, prone position, left lateral, supine position, Fowler's position 2, left lateral 2, prone position 2 and supine position 2. Each woman remained in each position for 6 minutes. For the statistical analyses, we used Wilcoxon's test for 2 paired samples when comparing the prone position with the other positions. The variables are presented in graphs showing the means and 95% confidence intervals. Trial Registration: Clinical Trial No. ISRCTN41359519. RESULTS:: All the parameters were within the standards of normality. There were no differences between positions in terms of maternal heart rate, diastolic blood pressure, oxygen saturation and fetal heart rate. However, there were significant decreases in respiratory rate and systolic blood pressure in prone position 2 compared with left lateral 2. There was an increase in oxygen saturation in prone position compared with Fowler's position and supine position 2 in both sequences. All the women reported feeling comfortable in the prone position. CONCLUSIONS:: The prone position was considered safe and comfortable and could be advantageous for improving oxygen saturation and reducing the systolic blood pressure and respiratory rate.

Comparison of Two- and Three-dimensional Ultrasonography in the Evaluation of Lesion Level in Fetuses with Spina Bifida.

PURPOSE: To evaluate the precision of both two- and three-dimensional ultrasonography in determining vertebral lesion level (the first open vertebra) in patients with spina bifida. METHODS: This was a prospective longitudinal study comprising of fetuses with open spina bifida who were treated in the fetal medicine division of the department of obstetrics of Hospital das Clínicas of the Universidade de São Paulo between 2004 and 2013. Vertebral lesion level was established by using both two- and three-dimensional ultrasonography in 50 fetuses (two examiners in each method). The lesion level in the neonatal period was established by radiological assessment of the spine. All pregnancies were followed in our hospital prenatally, and delivery was scheduled to allow immediate postnatal surgical correction. RESULTS: Two-dimensional sonography precisely estimated the spina bifida level in 53% of the cases. The estimate error was within one vertebra in 80% of the cases, in up to two vertebrae in 89%, and in up to three vertebrae in 100%, showing a good interobserver agreement. Three-dimensional ultrasonography precisely estimated the lesion level in 50% of the cases. The estimate error was within one vertebra in 82% of the cases, in up to two vertebrae in 90%, and in up to three vertebrae in 100%, also showing good interobserver agreement. Whenever an estimate error was observed, both two- and three-dimensional ultrasonography scans tended to underestimate the true lesion level (55.3% and 62% of the cases, respectively). CONCLUSIONS: No relevant difference in diagnostic performance was observed between the two- and three-dimensional ultrasonography. The use of three-dimensional ultrasonography showed no additional benefit in diagnosing the lesion level in the fetuses with spina bifida. Errors in both methods showed a tendency to underestimate lesion level.

Objetivo Avaliar a precisão da ultrassonografia bidimensional e tridimensional para a determinação do nível da lesão vertebral em casos de fetos portadores de espinha bífida. Métodos Estudo prospectivo longitudinal, compreendendo fetos portadores de espinha bífida assistidos no setor de medicina fetal de hospital de ensino do Sudeste do Brasil, entre os anos de 2004 e 2013. Foram incluídos 50 fetos portadores de espinha bífida pela ultrassonografia bidimensional e tridimensional (dois examinadores em cadamétodo) comrelação ao nível da lesão. O nível exato da lesão foi verificado usando radiografia após o nascimento. Resultados A ultrassonografia bidimensional estimou corretamente o nível de espinha bífida em 53,0% dos casos. Em 80,0% dos casos a estimativa ocorreu com erro de uma vértebra; 89,0% em até duas vértebras e de 100,0% em até três vértebras. A ultrassonografia tridimensional estimou corretamente o nível de espinha bífida em 50,0% dos casos. Em 82,0% dos casos, a estimativa ocorreu com erro de uma vértebra; 90,0% em até duas vértebras e de 100,0% em até três vértebras. Nos casos em que houve erro na estimativa do nível da lesão, tanto na avaliação bidimensional quanto na tridimensional, observou-se tendência a subestimar o nível da lesão vertebral (55,3% na avaliação bidimensional e 62,0% na tridimensional), ou seja, colocando o nível ultrassonográfico mais baixo que o observado no pós-natal. Conclusões Não houve diferenças relevantes entre o desempenho diagnóstico da ultrassonografia bidimensional e tridimensional para determinação do nível da lesão vertebral nos casos de fetos portadores de espinha bífida. Tendência a subestimação do nível de lesão nos casos em que houve erro tanto na ultrassonografia bidimensional quanto na tridimensional.

Fetal ductus arteriosus constriction and closure: analysis of the causes and perinatal outcome related to 45 consecutive cases.

OBJECTIVE: The aim of this study was to analyze the causes and perinatal outcome related to fetal ductus arteriosus constriction or closure at a single center over a 26-year period. METHODS: This was a retrospective analysis of 45 consecutive cases of constriction (n = 41) and closure (n = 4) from 1987 through 2013. Patients were divided into Group A (maternal use of non-steroidal anti-inflammatory drugs (NSAID), n = 29), Group B (idiopathic, n = 8), and Group C (other drugs not previously described, n = 8). RESULTS: The median gestational age at diagnosis was 34 weeks (range, 27-38), mean systolic and diastolic velocity in the ductus arteriosus was 2.01 ± 0.66 m/s and 0.71 ± 0.46 m/s, respectively. Among the 29 cases of NSAIDs, 27.5% (8/29) have taken a single day use and 75% multiple days/doses. Right ventricular dilatation was present in 82.2% of the fetuses, tricuspid insufficiency in 86.6%, and heart failure in 22.2%. Neonatal persistent pulmonary hypertension occurred in 17.7% of the patients. Late follow-up showed all 43 survivors alive and healthy with only two deaths from unrelated causes. CONCLUSIONS: The results of this study indicate that clinically significant ductal constriction may follow maternal exposure to single doses of NSAIDs. Unknown causes or other new substances were also described, such as naphazoline, fluoxetine, isoxsuprine, caffeine and pesticides. Echocardiographic diagnosis of ductal constriction led to an active medical approach that resulted in low morbidity of this group of patients.

Investigating 22q11.2 deletion and other chromosomal aberrations in fetuses with heart defects detected by prenatal echocardiography.

Congenital heart disease (CHD) is the most common birth defect and the leading cause of mortality in the first year of life. In fetuses with a heart defect, chromosomal abnormalities are very frequent. Besides aneuploidy, 22q11.2 deletion is one of the most recognizable chromosomal abnormalities causing CHD. The frequency of this abnormality varies in nonselected populations. This study aimed to investigate the incidence of the 22q11.2 deletion and other chromosomal alterations in a Brazilian sample of fetuses with structural cardiac anomalies detected by fetal echocardiography. In a prospective study, 68 fetuses with a heart defect were evaluated. Prenatal detection of cardiac abnormalities led to identification of aneuploidy or structural chromosomal anomaly in 35.3% of these cases. None of the fetuses with apparently normal karyotypes had a 22q11.2 deletion. The heart defects most frequently associated with chromosomal abnormalities were atrioventricular septal defect (AVSD), ventricular septal defect (VSD), and tetralogy of Fallot. Autosomal trisomies 18 and 21 were the most common chromosomal abnormalities. The study results support the strong association of chromosome alterations and cardiac malformation, especially in AVSD and VSD, for which a chromosome investigation is indicated. In fetuses with an isolated conotruncal cardiopathy, fluorescence in situ hybridization (FISH) to investigate a 22q11.2 deletion is not indicated.

Perinatal outcome of fetal atrioventricular block: one-hundred-sixteen cases from a single institution.

BACKGROUND: Fetal atrioventricular (AV) block is an uncommon lesion with significant mortality. Because of the rarity of this disorder, the natural course, extensive evaluation of untreated fetuses, and late follow-up remain unclear. METHODS AND RESULTS: Of the 116 consecutive cases of fetal AV block studied from 1988 to 2006, only 1 was terminated, and 75% were live births. Fifty-nine cases of AV block were associated with major structural heart disease, mainly left atrial isomerism (n=40), with only 26% of neonatal survivors. Of the 57 fetuses with normal cardiac anatomy, 41 (72%) were positive for maternal antinuclear antibodies, and 32 of these seropositive mothers did not receive any treatment. This untreated group had live-birth and 1-year infant survival rates of 93% and 90% [corrected], respectively. Five fetuses from seronegative mothers showed regression to sinus rhythm during pregnancy. The presence of major structural heart disease, hydrops, an atrial rate 90% of our untreated patients with isolated forms of AV block raises concerns about any decision to intervene with immunosuppressive agents.

Avaliação ultra-sonográfica, ecocardiográfica fetal e resultados perinatais em gestantes portadoras do HIV em uso de terapia anti-retroviral / Ultrasound examination, fetal echocardiography and prenatal outcome in HIV-positive pregnant women under antiretroviral therapy

OBJETIVO: descrever as alterações estruturais e/ou funcionais fetais à ultra-sonografia e à ecocardiografia fetais e os resultados perinatais em gestantes soropositivas para o vírus da imunodeficiência humana (HIV) em relação a um grupo controle de pacientes atendidas pelo pré-natal de baixo risco. MÉTODOS: foram avaliadas, prospectivamente, 109 gestantes soropositivas para o HIV em uso de anti-retrovirais (Grupo de Estudo, GE) e 200 gestantes controles (GC), sendo realizado acompanhamento ultra-sonográfico obstétrico mensal e ecocardiografia fetal e pós-natal com a avaliação do volume de líquido amniótico, da adequação do peso fetal, da presença de alterações estruturais fetais e dos resultados perinatais. RESULTADOS: foram observados oito casos de alterações estruturais fetais (7,3 por cento) contra dois (1 por cento) no GC (p=0,61). Observamos quatro casos de cardiopatia congênita e quatro de hidronefrose no GE, com diferença estatística para as cardiopatias (p=0,015). Foram diagnosticados, no GE, oito (7,3 por cento) casos de oligoidrâmnio e 11 (10 por cento) casos de polidrâmnio contra dois casos (1 por cento) de oligoidrâminio e nenhum de polidrâmnio (p de 0,004 e p<0,001, respectivamente). Onze recém-nascidos (10 por cento) foram pequenos para a idade gestacional no GE contra três (2,7 por cento) no GC (p=0,002). A incidência de prematuridade foi de 8,7 e 2,5 por cento nos grupos de estudo e controle, respectivamente (p=0,041). A taxa de óbito fetal foi de 5,5 por cento (seis casos) no GE, contra nenhum no GC (p=0,002). CONCLUSÕES: observamos maior prevalência de cardiopatia fetal e de alterações da quantidade de líquido amniótico no grupo estudado em relação ao GC. A taxa de óbito fetal no GE provavelmente está vinculada à presença de malformações fetais; já a incidência de neonatos pequenos para a idade gestacional e de prematuridade, está associada à terapia anti-retroviral e ao uso do tabaco e de drogas ilícitas.

PURPOSE: to evaluate fetal structural and/or functional abnormalities by ultrasound examination and fetal echocardiography, in pregnant women positive for human immunodeficiency virus (HIV). METHODS: we analyzed prospectively 109 HIV positive pregnant women under antiretroviral therapy (Study Group) and 200 low risk pregnant patients (Control Group). All of them were submitted to ultrasound scan and fetal and neonatal echocardiography once a month. The amniotic fluid volume, fetal growth, fetal structural and functional alteration and the perinatal outcome were evaluated. RESULTS: there were eight (7.3 percent) cases of fetal structural abnormality in the Study Group and two (1 percent) in the Control Group (p=0.616). There were four cases of congenital heart disease and four cases of hydronephrosis in the Study Group, with statistic significance (p=0.015) for the cardiac abnormalities. There were eight cases (7.3 percent) of oligohydramnios and 11 cases (10 percent) of polyhydramnios in the Study Group against two cases (1 percent) of oligohydramnios and none of polyhydramnios in the Control Group (p=0.004 and p<0.001). Eleven (10 percent) newborn babies were too small for their gestation age in the Study Group, against three (2.7 percent) in the Control Group (p=0,002). The incidence of preterm delivery was 8.7 and 2.5 percent in the Study and Control Groups respectively (p=0.041). It was observed six cases (5.5 percent) of fetal death in the Study Group and none in the Control Group (p=0.002). CONCLUSIONS: in the present study, we have observed higher prevalence of amniotic fluid volume and congenital heart abnormalities in the Study Group as compared to the Control Group. Statistical significance was found in both situations. The high fetal death rate found in the Study Group was probably due to fetal malformation, whereas the high prematurity rate and the prevalence of small size for the gestational age of the newborn babies were...

Effects of pelvic floor muscle training during pregnancy.

OBJECTIVE: The objective of the present study was to evaluate the effect of pelvic floor muscle training in 46 nulliparous pregnant women. METHODS: The women were divided into 2 groups: an exercise group and a control group. Functional evaluation of the pelvic floor muscle was performed by digital vaginal palpation using the strength scale described by Ortiz and by a perineometer (with and without biofeedback). RESULTS: The functional evaluation of the pelvic floor muscles showed a significant increase in pelvic floor muscle strength during pregnancy in both groups (P < .001). However, the magnitude of the change was greater in the exercise group than in the control group (47.4% vs. 17.3%, P < .001). The study also showed a significant positive correlation (Spearman's test, r = 0.643; P < .001) between perineometry and digital assessment in the strength of pelvic floor muscles. CONCLUSIONS: Pelvic floor muscle training resulted in a significant increase in pelvic floor muscle pressure and strength during pregnancy. A significant positive correlation between functional evaluation of the pelvic floor muscle and perineometry was observed during pregnancy.

INTRODUÇÃO: A gravidez traz importantes modificações hormonais e anatômicas que têm efeito sobre a musculatura do assoalho pélvico. A cinesioterapia aplicada à musculatura do assoalho pélvico na gestação pode ser grande aliada no controle das alterações músculo-esqueléticas. OBJETIVOS: Avaliar efeitos da cinesioterapia no assoalho pélvico durante a gravidez, por meio da perineometria com e sem "biofeedback" e da avaliação funcional do assoalho pélvico, e correlacionar os valores da avaliação funcional com as perineometrias. MÉTODOS: Estudamos 46 gestantes nulíparas em seguimento pré-natal no Departamento de Obstetrícia do Hospital das Clínicas da Universidade de São Paulo, entre novembro de 2003 e dezembro de 2004, com até 20 semanas de gestação, atendidas no Setor de Baixo-Risco, divididas em dois grupos: Grupo exercício (23 casos): pacientes submetidas à cinesioterapia para a musculatura do assoalho pélvico; e grupo controle (23 casos): sem a prática da cinesioterapia. Por 12 semanas, até a 36ª semana, seguiu-se um protocolo, com treinamento de 60 minutos semanais, executando-se quatro séries de 10 contrações destes músculos com seis segundos de manutenção e 12 segundos de relaxamento, em decúbitos distintos. Realizaram-se 2 avaliações: 1ª (até 20 semanas) e 2ª (36 semanas gestacionais), por meio da avaliação funcional do assoalho pélvico e da perineometria. RESULTADOS: Na avaliação funcional do assoalho pélvico, tanto o grupo exercício como o grupo controle apresentaram aumento significativo da 1ª avaliação para a 2ª avaliação. Para a perineometria sem "biofeedback", na 2ª avaliação, somente o grupo exercício obteve aumento significativo, com p < 0,001. Quanto à perineometria com "biofeedback", tanto o grupo exercício como o controle tiveram aumento significativo nos valores, porém o delta porcentual foi maior no grupo exercício. Houve correlação significativa e positiva entre a avaliação funcional do assoalho pélvico e as perineometrias...
