ABSTRACT

La mujer gestante sufre cambios fisiológicos y psicológicos durante los meses de embarazo que pueden derivar en problemas de salud bucal. A través de diversos estudios se observó que múltiples factores actúan como determinantes en lo que a la atención odontológica de la embarazada respecta, entre los cuales se pueden encontrar, la realidad sociocultural de la paciente, su nivel de instrucción educativo, sus conocimientos en cuanto a la atención odontológica, factores de riesgos, entre otros. El profesional odontólogo, tiene en sus manos recursos que pueden ser de gran ayuda por lo que su papel es de suma importancia, desde la educación preventiva, brindando conocimientos técnicos hasta la atención odontológica en sectores vulnerables. El objetivo de este trabajo consistió en reunir la evidencia que se corresponda con el análisis de los conocimientos y prácticas de salud bucal en mujeres embarazadas con el fin de organizar los trabajos hallados en un cuerpo de conocimiento fundamentado (AU)


The pregnant woman suffers physiological and psychological changes during the months of pregnancy that can lead to oral health problems. Through various studies it was observed that multiple factors act as determinants regarding dental care of the pregnant woman, among which can be found the sociocultural reality of the patient, her educational level of instruction, her knowledge regarding dental care, risk factors, among others. The dental professional has resources in her hands that can be of great help, so her role is of the utmost importance, from preventive education, providing technical knowledge to dental care in vulnerable sectors. The objective of this work was to gather the evidence that corresponds to the analysis of oral health knowledge and practices in pregnant women to organize the studies found in a well-founded body of knowledge (AU)

ABSTRACT

ABSTRACT Objective: To describe the morphology of the supra- and infraumbilical linea nigra in puerperal women. Methods: The study was conducted from September 2017 to April 2018, and included 157 puerperal women admitted for childbirth care at the Obstetrics Department of a public maternity hospital of the city of São Paulo (SP), Brazil. The abdomen of subjects was photographed on the first or second day postpartum, with the patient lying symmetrically in dorsal decubitus at a standardized distance. Contrast was slightly adjusted and the morphological pattern of supra and infraumbilical linea nigra in the proximity of the umbilical scar was characterized. The images were independently analyzed by two researchers and only the matching results from both observers were used. Results: Of the 157 observed cases, 139 (88.5%) images provided concordant results between the two researchers. Excluding 41 cases of absence or poor definition of the linea nigra, 98 images were analyzed. Supra- and infraumbilical linea nigra were analyzed separately and classified according to three directions (left, center and right of the umbilical scar). The combination of the supra- and infraumbilical images resulted in the formation of nine distinct patterns, being the most prevalent, in primiparous (72.2%) and multiparous women (50.0%), and the authors named as "anticlockwise spiralization of the linea nigra". Conclusion: The analysis of supra- and infraumbilical linea nigra in puerperal women showed a predominance of what the authors named "anti-clockwise spiralization of the linea nigra sign".


RESUMO Objetivo: Descrever a morfologia da linea nigra supra e infraumbilical em puérperas. Métodos: O estudo foi realizado no período de setembro de 2017 a abril de 2018 e incluiu 157 puérperas admitidas para o parto no Serviço de Obstetrícia de uma maternidade pública da cidade de São Paulo (SP). O abdome das pacientes foi fotografado no primeiro ou segundo dia pós-parto, com a paciente deitada simetricamente em decúbito dorsal a uma distância padronizada. O contraste foi ligeiramente ajustado, e o padrão morfológico da linea nigra supra e infraumbilical na proximidade da cicatriz umbilical foi caracterizado. As imagens foram analisadas independentemente por dois pesquisadores, e apenas os resultados concordantes dos dois observadores foram utilizados. Resultados: Dos 157 casos observados, 139 (88,5%) imagens apresentaram resultados concordantes entre os dois pesquisadores. Excluindo 41 casos de ausência ou má definição da linea nigra, 98 imagens foram analisadas. As linea nigra supra e infraumbilicais foram analisadas separadamente e classificadas de acordo com três direções (esquerda, centro e direita da cicatriz umbilical). A combinação das imagens supra e infraumbilicais resultou na formação de nove padrões distintos, sendo os mais prevalentes nas primíparas (72,2%) e multíparas (50,0%), o que os autores denominaram "espiralamento anti-horário da linea nigra". Conclusão: A análise das linea nigra supra e infraumbilical em puérperas mostrou predominância do que os autores denominaram "sinal do espiralamento anti-horário da linea nigra".

ABSTRACT

Abstract Objective To determine the effect of treadmill walking on maternal heart rate (MHR) and cardiotocographic parameters (basal fetal heart rate [FHR], active fetal movements [AFM], number of accelerations and decelerations, and short-term variation [STV] and long-term variation [LTV] of fetal heart rate) in pregnant women at 36 weeks. Methods A nonrandomized, open clinical trial involving 88 healthy pregnant women submitted to moderate intensity walking and computed cardiotocography in 3 20- minute periods (resting, treadmill walking, and postexercise recovery). Results The mean FHR decreased during walking (resting: 137 bpm; treadmill: 98 bpm; recovery: 140 bpm; p<0.001), with bradycardia occurring in 56% of the fetuses in the first 10minutes of exercise, and in 47% after 20minutes. Bradycardia was not detected in the other phases. The mean STV and HV were 7.9, 17.0, and 8.0 milliseconds (p<0.001) and 7.6, 10.8 and 7.6 bpm (p=0.002) in the resting, walking and recovery phases, respectively. Themean number of fetalmovements in 1 hour was 29.9, 22.2 and 45.5, respectively, in the 3 periods (p<0.001). In overweight/obese women, the mean FHR was lower (p=0.02). Following the logistic regression analysis, two variables remained significantly associated with bradycardia: maternal fitness in the 28th week of pregnancy (protective effect) and maternal weight (increased risk). Conclusion In healthy fetuses, physical exercise proved to be safe, since, although FHR and AFM decreased during treadmill walking, an increase in SVT and LTV was observed.


Resumo Objetivo Determinar o efeito da caminhada em esteira sobre a frequência cardíaca materna (FCM) e parâmetros cardiotocográficos (batimentos cardiofetais basais [BCFs], movimentos ativos fetais [MAFs], número de acelerações e desacelerações e variabilidade de curta [STV] e longa [LTV] duração da frequência cardíaca fetal) em gestantes na 36a semana. Métodos Foi realizado umensaio clínico não randomizado e aberto com 88 gestantes saudáveis submetidas a caminhada de moderada intensidade na esteira e a cardiotocografia computadoriza em 3 momentos de 20 minutos (antes, durante e após a caminhada). Resultados A média dos BCFs diminuiu durante a caminhada, retornando a níveis prévios (antes: 137 bpm; durante: 98 bpm; após: 140 bpm; p<0,001), com bradicardia ocorrendo em 56% dos fetos nos primeiros 10 minutos do exercício, e em 47% após 20 minutos. A bradicardia fetal não foi observada em outrosmomentos (antes ou depois). As médias da STV e da LTV foram 7,9, 17,0 e 8,0milissegundos (p<0,001) e 7,6, 10,7 e 7,6 bpm (p=0,002) antes, durante e após a caminhada, respectivamente. Amédia dos números dos MAFs em 1 hora foi 29,9, 22,2 e 45,5, respectivamente, nos três momentos (p<0,001). Nas mulheres com sobrepeso/obesidade, a média da FCM foi menor (p=0,02). Após a análise de regressão logística, duas variáveis permaneceram significativamente associadas a bradicardia: aptidão maternal na 28a semana de gravidez (efeito protetor) e peso materno (aumento do risco). Conclusão Em fetos saudáveis, o exercício físico mostrou-se seguro, uma vez que, embora os BCFs e osMAFs diminuam durante a caminhada na esteira, foi observado um aumento da SVT e da LTV.

ABSTRACT

ABSTRACT OBJECTIVE To determine the frequency of the registry of physical activity and rest recommendations made to pregnant women and to explore their associated factors in a prenatal care program of primary care public institutions in Bucaramanga, Colombia. METHODS An observational study was conducted. The sampling frame consisted of the medical records of the pregnant women who attended at least one prenatal care program between January 1 and December 31, 2012 (n = 2.932), in 21 primary care health centers. We analyzed sociodemographic variables, prenatal and clinical antecedents, and information related to health personnel and the organization of health centers as possible factors associated with the recommendations of physical activity and rest recorded in the clinical history. Logistic regression models were applied to explore associations with α = 0.10. RESULTS There was a frequency of 26.1% of PA recommendations and 3.6% of rest recommendation on record, issued by nutrition (97.3%) and medical (86.7%) professionals, respectively. The factors associated with the registration of physical activity recommendations were: being nulliparous pregnant (OR = 1.7), attending more than four Prenatal Care Attention Programs (OR = 2.2), having high or medium obstetric risk in the first prenatal care program (OR = 0.6), and being attended in the western (OR = 0.5) and eastern (OR = 0.2) administrative areas health centers. CONCLUSIONS The low frequency of physical activity recommendations found in the records makes it necessary to reinforce the management strategies of health centers and strengthen the monitoring and accompaniment to comply with the care protocols. In addition, it is necessary to train health teams on the benefits of physical activity and their proper prescription, considering the multiple benefits derived from their practice on the maternal-fetal health.


RESUMEN OBJETIVO Determinar la frecuencia del registro de recomendaciones de actividad física y reposo realizadas a las gestantes y explorar sus factores asociados, en un programa de atención de control prenatal de instituciones públicas de primer nivel de atención en Bucaramanga, Colombia. MÉTODOS Se realizó un estudio observacional. El marco muestral estuvo conformado por los registros médicos de las gestantes que asistieron al menos a un programa de atención de control prenatal entre el 1º de enero y 31 de diciembre de 2012 (n = 2,932), en 21 centros de salud de primer nivel de atención. Se analizaron variables sociodemográficas, antecedentes prenatales, antecedentes clínicos, e información relacionada con el personal de salud y la organización de los centros de salud como posibles factores asociados con las recomendaciones de actividad física y reposo registrados en la historia clínica. Se aplicaron modelos de regresión logística para explorar las asociaciones con un α = 0.10. RESULTADOS Se observó una frecuencia de 26.1% de registro de recomendaciones de AF y 3.6% de reposo, emitidas por parte de profesionales de nutrición (97.3%) y medicina (86.7%), respectivamente. Los factores asociados al registro de las recomendaciones de actividad física fueron: ser gestante nulípara (OR = 1.7), asistir a más de cuatro Programas de Atención de Control Prenatal (OR = 2.2), tener riesgo obstétrico alto o medio en el primer programa de atención de control prenatal (OR = 0.6) y ser atendidas en los centros de salud de las zonas administrativas de occidente (OR = 0.5) y oriente (OR = 0.2). CONCLUSIONES La baja frecuencia del registro de recomendaciones de actividad física encontrada, genera la necesidad de reforzar las estrategias de gestión de los centros de salud y fortalecer el monitoreo y acompañamiento en el cumplimiento de los protocolos de atención. Adicionalmente, es necesario capacitar a los equipos de salud sobre los beneficios de la actividad física y su prescripción adecuada, atendiendo a los múltiples beneficios derivados de su práctica sobre la salud materno-fetal.

ABSTRACT

A detecção superprecoce de gestação é de grande relevância quando se trata do aumento da produtividade dos rebanhos, na tentativa de redução do tempo de serviço desses animais. Por tal relevância, objetivou-se utilizar a ultrassonografia (US) Doppler como ferramenta para predição de gestação, avaliando a irrigação do corpo lúteo (CL), vinte dias após IATF. Setenta e três vacas mestiças foram avaliadas 20 dias após IATF por US transretal. Para obtenção do diâmetro do CL (DCL) e sua área (ACL) utilizou-se o modo B, na mensuração da área de vascularização (VCL) e seu percentual no CL (VCL%) empregou-se o Doppler Colorido. As imagens foram classificadas com base na quantidade de pixels coloridos e sua distribuição no CL, em dois grupos: diagnóstico preditivo negativo de gestação (DPN) e preditivo positivo (DPP). No mesmo dia, a funcionalidade do CL foi determinada pela concentração plasmática de P4. O diagnóstico de gestação definitivo foi realizado por US 35 dias após as IATFs. Utilizou-se o teste t de Student (com P<0,05) na avaliação das variáveis. Grupo gestantes apresentou médias superiores (P<0,05) para todas as variáveis ao Grupo Não Gestantes. O diagnóstico preditivo demonstrou 83,33% de especificidade, sensibilidade de 100% e acurácia de 91,79%. Conclui-se que a US doppler do CL aos 20 dias pós IATF é um método confiável no diagnóstico precoce de gestação.(AU)


The super early gestation detection is of great relevance considering the increase of the herds' productivity, in an attempt to reduce the time of service of these animals. Due to this relevance, this study aimed to use Doppler ultrasonography as a tool for gestation prediction, evaluating the luteal body (CL) irrigation twenty days after FTAI. 73 crossbred cows were evaluated 20 days after FTAI through trans rectal US. In order to obtain the diameter of the CL (DCL) and its area (ACL), B mode was used. The Color Doppler was applied to measure the vascularization area (CLV) and its percentage in the CL (VCL %). The images were classified, based on the number of colored pixels and their distribution in CL, in two groups: negative predictive diagnosis of gestation (NPD) and positive predictive value (PPV). On the same day, LC functionality was determined based on P4 plasma concentration. The definitive gestation diagnosis was confirmed through US 35 days after the FTAIs. Student's T test (with P<0.05) was used to evaluate the variables. Pregnant group presented higher averages (P<0.05) for all variables compared to the Non-Pregnant Group. The predictive diagnosis showed 83.33% of specificity, 100% of sensitivity and 91.79% of accuracy. The conclusion is that the US Doppler at 20 days post FTAI is a reliable method for early gestation diagnosis.(AU)

ABSTRACT

Background: During pregnancy, a number of changes affecting venous blood flow occur in the circulatory system, such as reduced vein wall tension or increased exposure to collagen fibers. These factors may cause blood stagnation, swelling of the legs, or endothelial damage and consequently lead to development of venous disease. Objectives: The aim of this study is to evaluate the effect of special footwear designed to improve blood circulation in the feet on venous blood flow changes observed during advancing phases of pregnancy. Methods: Thirty healthy pregnant women participated in this study at 25, 30, and 35 weeks of gestation. Participants were allocated at random to an experimental group (n = 15) which was provided with the special footwear, or a control group (n = 15). At each data collection session, Doppler measurements of peak systolic blood flow velocity and cross-sectional area of the right popliteal vein were performed using a MySonoU6 ultrasound machine with a linear transducer (Samsung Medison). The differences were compared using Cohen's d test to calculate effect size. Results: With advancing phases of pregnancy, peak systolic velocity in the popliteal vein decreased significantly in the control group, whereas it increased significantly in the experimental group. No significant change in cross-sectional area was observed in any of the groups. Conclusions: Findings in the experimental group demonstrated that wearing the footwear tested may prevent venous blood velocity from reducing during advanced phases of pregnancy. Nevertheless, there is a need for further investigation of the beneficial effect on venous flow of the footwear tested and its application


Contexto: Durante a gravidez, uma série de mudanças que afetam o fluxo venoso ocorrem no sistema circulatório, tais como menor tensão da parede venosa ou aumento da exposição a fibras de colágeno. Esses fatores podem causar estagnação sanguínea, inchaço das pernas ou dano endotelial e, consequentemente, levar ao desenvolvimento de doença venosa. Objetivos: O objetivo deste estudo foi avaliar o efeito do uso de calçados especiais projetados para melhorar a circulação sanguínea dos pés sobre as mudanças no fluxo venoso observadas nas fases avançadas da gravidez. Métodos: Trinta gestantes saudáveis participaram deste estudo às 25, 30 e 35 semanas de gestação. As participantes foram aleatoriamente designadas a um grupo experimental (n = 15) que recebeu calçados especiais, ou um grupo controle (n = 15). A cada sessão de coleta de dados, foram obtidas medidas Doppler do pico de velocidade do fluxo sanguíneo sistólico e da área transversal da veia poplítea direita, utilizando-se um aparelho de ultrassom MySonoU6 com transdutor linear (Samsung Medison). As diferenças foram comparadas utilizando-se o teste d de Cohen para calcular o tamanho do efeito. Resultados: Nas fases avançadas da gravidez, o pico da velocidade sistólica na veia poplítea diminuiu significativamente no grupo controle, porém aumentou significativamente no grupo experimental. Não houve mudanças significativas na área transversal da veia poplítea em nenhum dos grupos. Conclusões: Os achados do grupo experimental demonstraram que o uso dos calçados especiais testados pode evitar que a velocidade do fluxo venoso diminua nas fases avançadas da gravidez. No entanto, mais estudos são necessários para investigar os efeitos benéficos sobre o fluxo venoso do uso dos calçados testados e suas aplicações

ABSTRACT

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.

ABSTRACT

ABSTRACT Objective To evaluate the acute effects of maternal and fetal hemodynamic responses in pregnant women submitted to fetal Doppler and an aerobic physical exercise test according to the degree of effort during the activity and the impact on the well-being. Methods Transversal study with low risk pregnant women, obtained by convenience sample with gestational age between 26 to 34 weeks. The participants carry out a progressive exercise test. Results After the exercise session, reduced resistance (p=0.02) and pulsatility indices (p=0.01) were identified in the umbilical artery; however, other Doppler parameters analyzed, in addition to cardiotocography and fetal biophysical profile did not achieve significant change. Maternal parameters obtained linear growth with activity, but it was not possible to establish a standard with the Borg scale, and oxygen saturation remained stable. Conclusion A short submaximal exercise had little effect on placental blood flow after exercise in pregnancies without complications, corroborating that healthy fetus maintains homeostasis even in situations that alter maternal hemodynamics.


RESUMO Objetivo Avaliar os efeitos agudos de respostas hemodinâmicas maternas e fetais em gestantes submetidas a Doppler fetal e a um teste de exercício físico aeróbio, de acordo com o grau de esforço durante a atividade e o impacto sobre o bem-estar. Métodos Estudo transversal desenvolvido com gestantes de baixo risco, por amostra de conveniência com idade gestacional entre 26 e 34 semanas. As participantes realizam um teste de esforço progressivo. Resultados Na artéria umbilical, após sessão de exercício físico, identificou-se a redução do índice de resistência (p=0,02) e do índice de pulsatilidade (p=0,01), mas os demais parâmetros Doppler analisados, além da cardiotocografia e do perfil biofísico fetal, não obtiveram alteração significativa. Os parâmetros maternos obtiveram crescimento linear com a atividade, mas não foi possível estabelecer padrão com a escala de Borg, e a saturação de oxigênio se manteve estável. Conclusão O esforço submáximo curto teve pouco efeito sobre o fluxo de sangue da placenta após o exercício em gestações sem complicações, corroborando que o feto hígido mantém a homeostase mesmo em situações que alterem a hemodinâmica materna.

O estudo das interações orgânicas da gestação e as mudanças fisiológicas que estão ocorrendo nesta fase são de extrema importância para a avaliação clínica da fêmea gestante ou para estabelecer o diagnóstico de processos patológicos em andamento. O objetivo do presente estudo foi comparar o perfil das diversas proteínas sanguíneas (frações protéicas do soro - albumina, a1, a2, b, g globulinas e proteína total) durante o período gestacional e no diestro em cadelas. Foram utilizadas 40 fêmeas caninas da raça Dogue Alemão, em idade variando entre 2 a 7 anos, clinicamente saudáveis. Os animais foram separados em dois grupos, denominados Grupo não gestante (NG) e Grupo gestante (G), constituídos por 20 fêmeas em diestro e 20 fêmeas gestantes, respectivamente. Preconizou-se colheita de sangue semanalmente de cada animal durante 9 semanas. Nas fêmeas do grupo NG, as amostras foram colhidas a partir do início do diestro, até a detecção do início do anestro; no grupo G, as amostras foram colhidas do início do diestro até o momento da parição. A partir do soro sanguíneo, foram determinadas as concentrações de proteína total, albumina, a1, a2, b e g globulinas. Não houve diferença significativa quanto aos resultados de proteína sérica total entre a 1ª e 6ª semanas de gestação e diestro, havendo decréscimo gradual em ambos grupos. Já ao final da gestação (entre a 7ª e 9ª semanas), houve acréscimo significativo dos valores de proteína total, sugerindo ação anabólica. Os níveis de albumina sofreram queda da 1ª a 9ª semana, tanto no grupo gestante, como não-gestante, com diferença estatística entre os dois grupos na 7ª, 8ª e 9ª semanas. As concentrações de α1 globulina nas fêmeas gestantes sofreram acréscimo significativo a partir da 2ª semana, contudo, diferença estatística entre os grupos NG e G ocorreu somente na 8ª e 9ª semanas, coincidindo com a fase de preparação à parição. Houve aumento no perfil de α2 globulina entre a 2ª e 3ª semanas de gestação, porém tais valores não diferiram das fêmeas em diestro. Diferença significativa de α2 globulina foi observada apenas durante a 4ª, 5ª, 6ª, 8ª e 9ª semanas entre os dois grupos avaliados. As concentrações séricas de ß globulina nas cadelas não-gestantes foi superior às das fêmeas gestantes durante a 2ª, 4ª e 7ª semanas. Durante o primeiro terço da gestação (1ª a 3ª semana), foi observado queda dos valores de γ globulina, coincidente ao período pré implantacional e durante a formação dos sítios de implantação. Entre a 8ª e 9ª semanas de gestação, houve acréscimo significativo de γ globulina, possivelmente conseqüente ao aumento da produção de imunoglobulinas direcionadas à glândula mamária, como constituinte do colostro. Em conclusão, as proteínas alteram-se de forma evidente durante o período de gestação. Foi possível inferir diferenças nas funções biológicas das proteínas sanguíneas em cadelas gestantes e não gestantes. As proteínas determinadas estão envolvidas com o estímulo inflamatório durante a gestação, além dos mecanismos de regulação hormonal e preparação do organismo materno à lactação.(AU)


The study of the organic interaction and physiological adaptations during pregnancy is of utmost importance for clinical evaluation and diagnosis of pathological conditions of pregnant bitches. The aim of the present study was to compare the serum protein profile (total protein, albumin, a1, a2, b and g globulin) of pregnant and diestrous bitches. For this purpose, 40 healthy 2 to7-year-old Great Dane bitches were used. The bitches were allocated in two experimental groups: Non-pregnant group (NP; n=20) and pregnant group (P; n=20). From each female, blood was drawn weekly during 9 weeks, from the diestrous onset until the beginning of anestrus or parturition, respectively from NP and P groups. The concentration of total protein, albumin and a1, a2, b and g globulins were determined from serum samples. No statistical difference was found for total protein between 1st and 6th weeks of pregnancy or diestrus. In both groups, there was a progressive decline in total protein concentration. At the end of pregnancy (7th to 9th week), a significant increase in total protein was verified, suggesting an anabolic process. Albumin concentration decreased between the 1st and 9th week in both groups, however, more markedly in the P group (with significant difference between groups at 7th, 8th and 9th week). The levels of α1 globulin in pregnant bitches increased significantly from the 2nd week on. Statistical difference was observed between groups only at the 8th and 9th week, during which a preparatory phase for parturition occurs. A significant rise in α2 globulin was shown between the 2nd and 3rd week of gestation, however without difference from the NP group. There was significant difference for α2 globulin between groups at the 4th, 5th, 6th, 8th and 9th week. Serum concentration of b globulin in diestrous bitches was superior than pregnant bitches at the 2nd, 4th and 7th week. During early gestation (1st to 3rd week) there was a decrease in g globulin, simultaneously to the preimplantation period and formation of implantation sites. An increase in g globulin was shown between the 8th and 9th week in pregnant bitches, possibly due to the increase in immunoglobulin synthesis targeting the mammary gland to form the colostrum. In conclusion, markedly changes in protein profile occur during gestation. It was possible to state different biological function of blood proteins in pregnant and diestrous bitches. The determined proteins are enrolled in the inflammatory stimulus during gestation, as well as in the hormonal regulatory mechanisms and maternal preparatory process to lactation.(AU)

ABSTRACT

ABSTRACT Purpose: To investigate subfoveal choroidal thickness (SFCT) in patients with pre-eclampsia using enhanced depth imaging optical coherence tomography (EDI-OCT). Methods: A sample of 73 pregnant women was studied over 28 weeks of gestation. The sample was divided into two groups: one comprising pre-eclamptic pregnant women (n=32), and the other comprising healthy pregnant women (n=41). The SFCT was determined for all patients using EDI-OCT during pregnancy and at the third month of the postpartum period. Results: The SFCTs in pre-eclamptic pregnant women were 351.97 ± 22.44 and 332.28 ± 20.32 µm during the pregnancy and postpartum periods (p<0.001), respectively, whereas these values in healthy pregnant women were 389.73 ± 49.64 and 329.78 ± 22.36 µm (p<0.001), respectively. During pregnancy SFCT in pre-eclamptic pregnant women was significantly thinner than that in healthy pregnant women (p<0.001). However, there was no statistically significant difference during the postpartum period (p=0.623). Conclusions: The results suggest that SFCT is significantly decreased in pre-eclamptic pregnant women than in healthy pregnant women, despite no statistically significant difference in SFCT existing between the groups during the postpartum period.


RESUMO Objetivo: Investigar espessura subfoveal coroidal (SFCT) em pacientes com pré-eclâmpsia usando imagens de tomografia de coerência óptica de profundidade otimizada (EDI-OCT). Método: Uma amostra de 73 mulheres grávidas foi estudado ao longo de 28 semanas de gestação. A amostra foi dividida em dois grupos: um com mulheres grávidas com pré-eclâmpsia (n=32), o outro com as mulheres grávidas saudáveis (n=41). SFCT foi determinada em todos os pacientes utilizando EDI-OCT durante a gravidez e no terceiro mês do período pós-parto. Resultados: Os SFCTs em gestantes com pré-eclâmpsia foram 351,97 ± 22,44 µm e 332,28 ± 20,32 µm durante o período de gravidez e pós-parto (p<0,001), respectivamente. Estes valores em mulheres grávidas saudáveis foram 389,73 ± 49,64 µm e 329,78 ± 22,36 µm (p<0,001), respectivamente. Durante a gravidez o SFCT foi significantemente mais fino em mulheres com pré-eclâmpsia quando comparado com as mulheres saudáveis (p<0,001). No entanto, não houve diferença estatisticamente significante no período pós-parto (p=0,623). Conclusões: Os resultados sugerem que SFCT é significativamente mais fino em gestantes com pré-eclâmpsia do que nas mulheres grávidas saudáveis, apesar de não haver diferença estatisticamente significativa na SFCT entre os grupos durante o período pós-parto.

ABSTRACT

This study assessed the association between oral health knowledge and practices of pregnant Saudi women selected from visitors to a government hospital in Dammam, Saudi Arabia in 2014. Women answered questions on oral health knowledge during pregnancy and knowledge of infant oral health. Most women [> 70%] knew that dental caries in children can be prevented, that pregnancy affects oral health and that dental treatment during pregnancy can negatively affect infants. Most women [> 80%] performed oral hygiene procedures but only 18% regularly visited the dentist. In a regression analysis, oral health knowledge was not significantly associated with reported oral hygiene practices. Women who visited the dentist regularly were more likely to know how to prevent caries in children, and that dental treatment during pregnancy and infant health were associated

ABSTRACT

Good oral health is important in pregnancy but little is known about the oral health and knowledge and practices of pregnant Sudanese women. This cross-sectional study was conducted to address this gap. A sample of 420 pregnant women attending the prenatal clinic at Omdurman maternity hospital were interviewed and examined for caries and periodontal disease. The mean age of the women was 27.1 [SD 5.8] years, 52.4% had > primary school education and 7.1% were employed. Only 12% had a high level of oral health knowledge and 21.2% a positive attitude towards oral health. Most of the women [65.9%] had poor oral health practices; only 10.2% had visited a dentist during pregnancy. On clinical examination, 58.6% had healthy gums while 12.1% had bleeding gums and 22.9% had calculus. The mean decayed, missing and filled teeth value was 1.16 in the age group 16-19 years and 3.49 in age group >/= 20 years. These findings suggest the need for oral health programmes as part of prenatal care for pregnant Sudanese women

ABSTRACT

Introdução: A hipertensão é uma das mais graves patologias gestacionais, levando a um aumento importante da morbimortalidade materna e perinatal. Este estudo teve como objetivo determinar a correlação entre o número de internações hospitalares em primigestas com distúrbios hipertensivos na gestação e variação sazonal. Métodos: Estudo prospectivo ecológico entre todas as primigestas com idade gestacional maior de 20 semanas que internaram no Centro Obstétrico do Hospital de Clínicas de Porto Alegre num período de 12 meses. A frequência de internações por distúrbios hipertensivos foi comparada nos diferentes meses e estações do ano e também em relação à temperatura média e mínima do dia da internação e da semana anterior. Resultados: Foram estudadas 1.327 primigestas com idade média de 20,7 anos e idade gestacional média de 38,6 semanas. Entre estas, 232 (17,5%) apresentaram alteração na pressão arterial, sendo que 9,7% apresentaram pré-eclâmpsia (PE) e 7,5% outros distúrbios hipertensivos da gestação. Não houve associação significativa entre a frequência de internações por distúrbios hipertensivos e a temperatura média ou mínima do dia ou da semana anterior à internação. Ao longo do ano, ocorreu variação significativa (p < 0,05) na frequência de internações por pré-eclâmpsia, sendo esta maior no mês de setembro (15,1% das internações), marcando a transição entre o inverno e primavera. Conclusão: As variações da temperatura têm influência no número de internações por hipertensão na gestação, sendo essa informação útil no planejamento do sistema de saúde e da disponibilidade de leitos hospitalares.


Introduction: Hypertension is one of the most severe pregnancy disorders, leading to a significant increase of maternal and perinatal morbidity and mortality. This study aimed to determine the correlation of the number of hospital admissions of primiparous women with hypertensive disorders and seasonal variation. Methods: A prospective ecologic study of all primiparous women who were admitted to the Obstetric Center of Hospital de Clínicas de Porto Alegre at 20 or more weeks of gestation in 12 months. The frequency of hospital admissions was compared in different months and seasons of the year and with regard to mean or minimum temperature of the day and the week before admission. Results: A total of 1,327 primiparous women were studied, with average age of 20.7 years and mean gestational age of 38.6 weeks. Of these, 232 (17.5%) had hypertensive disorders, 9.7% of which had pre-eclampsia and 7.5% others hypertensive disorders. We observed no differences between the number of admissions and mean or minimum temperature on the day of admission nor during the week before the diagnosis. There was a significant variation (p < 0.05) in the number of admissions for pre-eclampsia by month, with the highest frequency in September (15.1% of admissions), which marks a transition from winter to spring. Conclusions: Variations in temperature influence the number of hospital admissions for hypertensive disorders. This information is very important to plan public health services and availability of hospital beds

ABSTRACT

Objective: To evaluate the effects of sleep restriction during pregnancy on maternal care and maternal aggression in a rodent model. Methods: Twenty-three female Wistar rats were assigned to one of two groups: control (n=12) or sleep restriction (n=11) during the entire pregnancy. At the fifth postpartum day, the animals were subjected to the resident-intruder paradigm and to the pup retrieval test. Results: Sleep restriction during pregnancy had no direct effects on maternal care. Regarding aggressive behavior, defensive aggression was increased by sleep loss, with a lower responsiveness threshold to hostile environmental stimuli. Sleep deprivation during gestation also reduced self-grooming behavior. Conclusion: Taking increased self-grooming as a behavioral correlate of anxiety in rodents, this study provides evidence that lactating dams were in a condition of reduced anxiety. From an adaptive perspective, this pattern of stress response may function to ensure proper maternal behavior, thereby guaranteeing the survival and viability of the litter. Under a translational perspective, the present article confronts the importance of biological and adaptive features to rodent maternal behavior with the relevance of sociocultural factors to the human mother-infant relationship and to the onset of postpartum depression.

ABSTRACT

Avaliaram-se a proporção volumétrica dos constituintes do corpo lúteo e a distribuição de células lúteas com grânulos citoplasmáticos no corpo lúteo de animais Nelore ao longo da gestação e em animais não gestantes. Foram coletados ovários com corpos lúteos de 24 animais abatidos em frigorífico. Os animais foram distribuídos em dois grupos: gestantes e não gestantes. A idade gestacional foi determinada pela medição do comprimento apicocaudal do feto. Os ovários foram distribuídos segundo o trimestre gestacional: primeiro - gestação de até 90 dias; segundo - de 91 a 180 dias; e terceiro - de 181 a 270 dias. Os corpos lúteos, processados para inclusão em paraplast, foram avaliados em microscópio de luz. Na proporção volumétrica do corpo lúteo, os constituintes avaliados foram citoplasma e núcleo de células lúteas, tecido conjuntivo e fibroblastos, células endoteliais e pericitos e vasos sanguíneos. A proporção volumétrica de citoplasma de células lúteas reduziu de 46,1±2,8% para 37,9±3,5% e a de núcleo de células lúteas reduziu de 9,2±1,0% para 6,2±1,0%, do primeiro para o segundo trimestre. A proporção de tecido conjuntivo e fibroblastos aumentou de 20,9±5,4%, no primeiro trimestre, para 34,0±4,2%, no segundo trimestre. Grânulos citoplasmáticos foram evidenciados pelas técnicas histoquímicas xylidine ponceau e azul de bromofenol, que indicam sua provável composição proteica. A quantidade de células maiores com grânulos aumentou significativamente de 2,3±1,9%, no primeiro trimestre, para 25,5±20,3%, no segundo. A proporção volumétrica de citoplasma e núcleo de células lúteas diminuiu ao longo da gestação, e a de tecido conjuntivo aumentou. A quantidade de células lúteas maiores contendo grânulos também aumentou ao longo da gestação.(AU)


The purpose of this study was to evaluate, in cycling and pregnant Nelore cows, the volumetric proportion of the corpus luteum and the distribution of lutein cells with cytoplasmic granules. Twenty four ovaries with corpus luteum were collected in a slaughterhouse. The ovaries were distributed into two groups: pregnant and non-pregnant cows. The group of pregnant cows was divided according to the stage of pregnancy, by the crown-rump fetus length: 1st third - until 90 days, 2nd third - between 91 and 180 days and 3rd third - between 181 and 270 days. The corpus luteum were processed for inclusion in paraplast, and slides were stained for analysis in light microscopy. The constituents quantified in the volumetric proportion were: lutein cells cytoplasm and nucleus, connective tissue and fibroblasts, endothelial cells and pericyte and blood vessels. The volumetric proportion of lutein cells cytoplasm decreased significantly from 46.1±2.8% to 37.9±3.5%, and also decreased significantly in the nucleus from 9.2±1.0% to 6.2±1.0% between the first and the second trimester of pregnancy. The amount of connective tissue and fibroblasts increased significantly throughout gestation, with 20.9±5.4% on the first trimester and 34.0±4.2% on the second. Granules were evidenced by the histochemical technique of Xylidine Ponceau and Bromophenol blue, indicating their probable protein composition. The amount of lutein cells with granules increased throughout gestation, but significant difference was observed only between the first (2.3±1.9%) and second trimester (25.5±20.3%). The cytoplasmic and nucleus volumetric proportion decreased during pregnancy and the volumetric proportion of connective tissue increased. The amount of lutein cells with granules increased throughout pregnancy.(AU)
