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.

Background: Most of the obese patients undergoing an anti-reflux operation experience recurrence of gastroesophageal reflux disease (GERD). Laparoscopic Roux-en-Y gastric bypass (LRNYGB) has been accepted as the bariatric surgery of choice for a previous GERD-operated obese patients. Methods: We present 85 consecutive patients from a single institution, previously submitted to antireflux surgery and then to LRNYGB. Preoperative endoscopy was carried out in all patients; 49 (57.64%) patients had findings of fundoplication failure or signs of persistent GERD, of those 20 (40.81%) with esophagitis. Results: From the bypass, per or postoperative minor to moderate complications occurred in 12 patients (14.11%): 2 (2.35%) conversions to laparotomy, 1 (1.17%) melena, 8 (9.41%) stenosis of gastrojejunostomy, treated by a simple endoscopic dilatation with a balloon, and 1 (1.17%) gastrogastric fistula. A follow-up endoscopy of 79 of 85 (92.9%) patients was carried out after 6 months of LRNYGB. Eight of 79 (10.12%) patients had persistent esophagitis that represented 40% (8 of 20 patients) of persistent reflux esophagitis even after LRNYGB. All of them were men. Conclusion: LRNYGB after laparoscopic fundoplication is a feasible procedure with an excepted higher rate of complications because of the complexity of the procedure. Nevertheless esophagitis still persisted in many of those patients.

Our aim was to develop and apply a comprehensive noninvasive prenatal test (NIPT) by using high-coverage targeted next-generation sequencing to estimate fetal fraction, determine fetal sex, and detect trisomy and monogenic disease without parental genotype information. We analyzed 45 pregnancies, 40 mock samples, and eight mother-child pairs to generate 35 simulated datasets. Fetal fraction (FF) was estimated based on analysis of the single nucleotide polymorphism (SNP) allele fraction distribution. A Z-score was calculated for trisomy of chromosome 21 (T21), and fetal sex detection. Monogenic disease detection was performed through variant analysis. Model validation was performed using the simulated datasets. The novel model to estimate FF was robust and accurate (r2= 0.994, p-value < 2.2e-16). For samples with FF > 0.04, T21 detection had 100% sensitivity (95% CI: 63.06 to 100%) and 98.53% specificity (95% CI: 92.08 to 99.96%). Fetal sex was determined with 100% accuracy. We later performed a proof of concept for monogenic disease diagnosis of 5/7 skeletal dysplasia cases. In conclusion, it is feasible to perform a comprehensive NIPT by using only data from high coverage targeted sequencing, which, in addition to detecting trisomies, also make it possible to identify pathogenic variants of the candidate genes for monogenic diseases.

Contexto: A cirurgia bariátrica é considerada a melhor opção para o tratamento da obesidade, cujos pacientes são considerados de alto risco para fenômenos tromboembólicos. Objetivos: Comparar o uso de doses diferentes de heparina de baixo peso molecular (HBPM) na profilaxia da trombose venosa profunda (TVP) em pacientes candidatos à cirurgia bariátrica em relação ao risco de TVP, alteração na dosagem do fator anti-Xa e sangramento pré ou pós-operatório. Métodos: Estudo comparativo transversal em pacientes submetidos à cirurgia bariátrica distribuídos em dois grupos, que receberam doses de HBPM de 40 mg (grupo controle, GC) e 80 mg (grupo de estudo, GE). Foram avaliados por ultrassonografia vascular e dosagem de KPTT, TAP, plaquetas e fator anti-Xa. Resultados: Foram avaliados 60 pacientes, sendo 34 no GC e 26 no GE. Foi observada diferença significativa somente no peso (p = 0,003) e índice de massa corporal (p = 0,018) no GE em relação ao GC. Não houve diferença na dosagem de KPTT, TAP, plaquetas e fator anti-Xa entre os grupos. Não foram detectados TVP ou sangramentos significativos em ambos os grupos. Conclusões: Não houve diferença estatisticamente significativa na utilização de doses maiores de HBPM na profilaxia da TVP em pacientes candidatos à cirurgia bariátrica em relação ao risco de TVP, dosagem do fator anti-Xa e sangramento pré ou pós-operatório


Background: Bariatric surgery is considered the best treatment option for patients with obesity who are classed as high risk for thromboembolic events. Objectives: To compare two different doses of low weight molecular heparin (LWMH) for prevention of deep venous thrombosis (DVT) in candidates for bariatric surgery, in terms of DVT risk, abnormal anti-Xa levels, and preoperative and/or postoperative bleeding. Methods: A cross-sectional comparative study of bariatric surgery patients divided into two groups given different doses of LWMH; 40 mg of LWMH (control group, CG) and 80 mg of LWMH (study group, SG), both evaluated by vascular ultrasonography (VU) and according to the results of PTT, PT, platelets, and anti-Xa factor assays. Results: Sixty patients were evaluated, 34 in the CG and 26 in the SG. The only significant differences between the patients in the SG and the CG were weight (p = 0.003) and body mass index (p = 0.018). There were no differences between the groups in PTT, PT, platelets, or anti-Xa factor levels. There was no DVT or significant bleeding in either group. Conclusions: There were no statistical differences when higher doses of LWMH were used for prevention of DVT in bariatric surgery patients, in terms of DVT risk, anti-Xa factor levels, or preoperative and postoperative bleeding

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.

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.

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.

OBJECTIVES: The proper nodal staging of non-small cell lung cancer is important for choosing the best treatment modality. Although computed tomography remains the first-line imaging test for the primary staging of lung cancer, its limitations for mediastinum nodal staging are well known. The aim of this study is to evaluate the accuracy of hybrid single-photon emission computed tomography and computed tomography using 99mTc-sestamibi in the nodal staging of patients with non-small cell lung cancer and to identify potential candidates for surgical treatment. METHODS: Prospective data were collected for 41 patients from December 2006 to February 2009. The patients underwent chest computed tomography and single-photon emission computed tomography/computed tomography examinations with 99mTc-sestamibi within a 30-day time period before surgery. Single-photon emission computed tomography/computed tomography was considered positive when there was focal uptake of sestamibi in the mediastinum, and computed tomography scan when there was lymph nodes larger than 10 mm in short axis. The results of single-photon emission computed tomography and computed tomography were correlated with pathology findings after surgery. RESULTS: Single-photon emission computed tomography/computed tomography correctly identified six out of 19 cases involving hilar lymph nodes and one out of seven cases involving nodal metastases in the mediastinum. The sensitivity, specificity, positive predictive value, and negative predictive value for 99mTc-sestamibi single-photon emission computed tomography/computed tomography in the hilum assessment were 31.6%, 95.5%, 85.7%, and 61.8%, respectively. The same values for the mediastinum were 14.3%, 97.1%, 50%, and 84.6%, respectively. For the hilar and mediastinal lymph nodes, chest tomography showed sensitivity values of 47.4% and 57.1%, specificity values of 95.5% and 91.2%, positive predictive values of 90% and 57.1% and negative predictive values of 67.7% and 91.2%, respectively. CONCLUSION: Single-photon emission computed tomography/computed tomography with 99mTc-sestamibi showed very low sensitivity and accuracy for the nodal staging of patients with non-small cell lung cancer, despite its high level of specificity. In addition, the performance of single-photon emission computed tomography/computed tomography added no relevant information compared to computed tomography that would justify its use in the routine preoperative staging of non-small cell lung carcinoma.

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.

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.

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...

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...
