Mother's stress, mood and emotional involvement with the infant: 3 months before and 3 months after childbirth

Adverse effects of maternal anxiety and depression are well documented, namely on the foetus/child behaviour and development, but not as much attention has been given to the mother's emotional involvement with the offspring. To study mother's prenatal and postpartum stress, mood and emotional involvement with the infant, the State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale and the Mother-to-Infant Bonding Scale were filled in and cortisol levels were measured, 3 months before and 3 months after childbirth, in a sample of 91 Portuguese women. From pregnancy to the postpartum period, mother's cortisol levels, anxiety and emotional involvement toward the child decrease. No significant change was observed regarding mother's depression. Mother's depression predicted a worse emotional involvement before childbirth, while mother's anxiety predicted a worse emotional involvement with the infant after childbirth. Additionally, pregnant women with a worse emotional involvement with the offspring are at risk of poorer emotional involvement with the infant and higher anxiety and depression at 3 months postpartum. It should be given more attention to mother's poor emotional involvement with the offspring during pregnancy, as it interferes with her emotional involvement with the infant and her psychological adjustment 3 months after childbirth.

Prevalência e preditores de sintomatologia depressiva após o parto

Contexto: A depressão pós-parto é uma patologia que ocorre nas primeiras semanas após o parto com conseqüências negativas não só para a mãe, como também para o bebê e para a família. Objetivo: Examinar a prevalência de depressão após o parto, bem como as circunstâncias suscetíveis de predizer a sintomatologia depressiva 1 semana e 3 meses após o parto. Métodos: 197 grávidas preencheram o Questionário de Antecipação do Parto (QAP) (Costa et al., 2005a) no segundo trimestre de gestação. Na primeira semana após o parto, responderam ao Questionário de Experiência e Satisfação com o Parto (QESP) (Costa et al., 2005b) e à Edinburgh Postnatal Depression Scale (EPDS) (Augusto et al., 1996), esta última aplicada novamente no terceiro mês do puerpério. Resultados: Uma percentagem significativa de mulheres encontra-se clinicamente deprimida (EPDS ≥ 13) na primeira semana e 3 meses após o parto (12,4% e 13,7%, respectivamente). Das que têm EPDS ≥ 13 na primeira semana, 25% estão ainda deprimidas 3 meses após o parto. Circunstâncias relativas à saúde física, à experiência emocional de parto e ao primeiro contato com o bebê predizem a sintomatologia depressiva na primeira semana do puerpério. A sintomatologia depressiva na primeira semana após o parto e a experiência emocional negativa de parto predizem a sintomatologia depressiva 3 meses após o parto. Conclusões: Constata-se a importância da experiência emocional de parto e do primeiro contato com o bebê, enfatizando a necessidade de atender às necessidades psicológicas da mulher.

Psychological approach to endometriosis: Women's pain experience and quality of life improvement

Endometriosis is a chronic condition affecting 10 to15% of women in childbearing age. Understanding the impact of this disease on women’s well-being is still a challenge, namely to intervene. Pain is the most current and troublesome symptom. Although medical treatments for pain relief are effective, recurrence rate remains significant, calling for a better understanding and development of new approaches for pain management. A group Cognitive Behavioral Therapy (CBT) for management of associated co-morbidities is suggested, paying special attention to Chronic Pelvic Pain (CPP). CBT design can be grounded on information collected from focus groups and a one-group exploratory trial. Evaluation of therapy effectiveness is possible to be performed by comparing group CBT to Usual Care (UC) and Support Group (SG) in a randomized controlled trial. Research in this area could represent an important step in providing a solution to the management of endometriosis and, to the best of our knowledge, the first national psychological approach for its understanding and treatment.

Partner relationships during pregnancy in anxious and depressed women and men

To assess anxiety, depression and relationship satisfaction in both women and men during pregnancy, the State Anxiety Inventory (STAI), The Center for Epidemiological Studies-Depression Scale (CES-D) and The Relationship Questionnaire (RQ) were administered during the second trimester to a sample of 59 pregnant women and their partners. Anxious pregnant women rated their relationships as less positive. Depressed pregnant women also rated their relationships as less positive. The women’s anxiety scores were predictive of their positive and negative relationship scores. The women and their partners’ negative relationship scores were also predictive of each others’ negative relationship scores. These results highlight the importance of targeting anxiety as well as depression, and pregnant women as well as their partners in prenatal intervention programs.

Utentes da Consulta Externa de Ginecologia/Obstetrícia da Maternidade Júlio Dinis

Com o objectivo de fazer a caracterização da situação social e demográfica e das condições de saúde médica e psicológica das utentes da Consulta Externa de Ginecologia/Obstretícia da Maternidade Júlio Dinis e de seus companheiros, duzentas mulheres e cento e setenta e cinco homens (N=375) foram entrevistados com base num questionário desenhado para o efeito, durante o primeiro trimestre de gestação. Observamos o desfavorecimento social e económico da amostra, particularmente no grupo das mulheres. Constatamos que a situação matrimonial e familiar é estável; no entanto, muitos agregados familiares são recentes, incluem outros familiares e este é um primeiro filho do casal. A rede de apoio social e emocional da amostra é geralmente constituída por familiares, estando mais presente para as mulheres do que para os homens e muitas vezes o companheiro não é referido como confidente, sobretudo pelas mulheres. A gestação não é geralmente de risco; não obstante, a presença frequente de problemas psicológicos uma pior aceitação inicial da gravidez no caso das mulheres. Os hábitos de vida tornam-se mais saudáveis com a gestação; no entanto, é ainda elevado o consumo de substâncias, como o tabaco, pela grávida. Problemas ginecológicos e obstétricos foram referidos, assim como a presença de adversidades na história psicológica e desenvolvimental dos participantes. Concluímos que as utentes da Consulta Externa de Ginecologia/Obstetrícia da Maternidade Júlio Dinis e seus companheiros apresentam indicadores relevantes de risco médico, psicológico e social que devem ser considerados na prestação de melhores cuidados de saúde.

Qualidade da vinculação e dos relacionamentos significativos na gravidez

O estudo apresentado neste artigo destinou-se a investigar a qualidade da vinculação e das relações significativas na gravidez. Mais precisamente, teve por objectivos (1) determinar as características sociais e demográficas e as condições anteriores de existência que se associam e permitem prever um estilo de vinculação (in)seguro e (2) estimar o impacto do estilo de vinculação na qualidade do relacionamento e do apoio por parte do companheiro e de uma outra pessoa significativa, na gravidez. Uma amostra de 130 grávidas (66 adolescentes e 64 adultas) foi avaliada no último trimestre de gestação quanto ao estilo de vinculação e à qualidade do relacionamento e do apoio por parte do companheiro e de uma outra pessoa significativa (com base na Attachment Style Interview, ASI; Bifulco, Figueiredo, Guedeney, Gorman, Hays et al., 2004; Bifulco, Moran, Ball & Bernazzani, 2002a; Bifulco, Moran, Ball & Lillie, 2002b). A amostra foi recolhida na Maternidade de Júlio Dinis (Porto) e é bastante heterogénea do ponto de vista social e demográfico, em características como: a idade, o nível educacional, o estado civil, o estatuto ocupacional e o tipo de agregado familiar, embora fundamentalmente constituída por grávidas primíparas. Os resultados mostram que um estilo inseguro de vinculação pode ser previsto na sequência de separação ou divórcio parental durante a infância ou adolescência e quando a grávida está desempregada, e que a gravidez na adolescência se associa ao estilo de vinculação desligado. Mostram ainda que um estilo inseguro de vinculação permite prever um pior relacionamento na gravidez, quer com o companheiro, quer com a outra pessoa significativa, principalmente a presença de relações discordantes com o companheiro e de relações apáticas com a outra pessoa significativa. As estratégias emaranhadas afectam a relação com o companheiro (em aspectos como menos confiança, menos suporte emocional e mais interacção negativa), mas não a relação com a outra pessoa significativa; enquanto as estratégias desligadas afectam a relação com a outra pessoa significativa (em aspectos como menos actividades partilhadas e menos interacção positiva), mas não a relação com o companheiro, e as estratégias amedrontadas afectam o relacionamento, tanto com o companheiro (em aspectos como menor sentimento de ligação) quanto com a outra pessoa significativa (em aspectos como menos confiança). De acordo com a Teoria da Vinculação, conclui-se que condições adversas de existência (anteriores e actuais) propiciam vinculação insegura e que o estilo de vinculação interfere na qualidade do relacionamento com o companheiro e com outras pessoas significativas, nomeadamente na capacidade da grávida recorrer a apoio.

Step towards to improve the voluntary interruption of pregnancy by means of business intelligence

With the implementation of Information and Communication Technologies in the health sector, it became possible the existence of an electronic record of information for patients, enabling the storage and the availability of their information in databases. However, without the implementation of a Business Intelligence (BI) system, this information has no value. Thus, the major motivation of this paper is to create a decision support system that allows the transformation of information into knowledge, giving usability to the stored data. The particular case addressed in this chapter is the Centro Materno Infantil do Norte, in particular the Voluntary Interruption of Pregnancy unit. With the creation of a BI system for this module, it is possible to design an interoperable, pervasive and real-time platform to support the decision-making process of health professionals, based on cases that occurred. Furthermore, this platform enables the automation of the process for obtaining key performance indicators that are presented annually by this health institution. In this chapter, the BI system implemented in the VIP unity in CMIN, some of the KPIs evaluated as well as the benefits of this implementation are presented.

Prevalence of Cardiac Arrhythmias During and After Pregnancy in Women with Chagas' Disease without Apparent Heart Disease

OBJECTIVE: To evaluate cardiac arrhythmias during and after pregnancy in women with Chagas' disease without apparent heart disease using dynamic electrocardiography. METHODS: Twenty pregnant women with Chagas' disease without apparent heart disease aged 19 to 42 years (26.96 ± 3.6) and a control group of 20 non-chagasic pregnant patients aged 16 to 34 years (22.5 ± 4.8). The patients were submitted to passive hemagglutination and indirect immunofluorescence for the detection of Trypanosoma cruzi evaluation, and electrocardiography, echocardiography and 24-h dynamic electrocardiography. RESULTS: Supraventricular premature depolarizations were observed in 18 (90%) patients and ventricular premature depolarization in 11 (55%) patients of both groups during pregnancy. After delivery, supraventricular premature depolarizations were present in 13 (60%) chagasic patients and in 16 (89.4%) control patients (P<=0.05). Ventricular premature depolarization were observed in 9 (45%) chagasic patients and 11 (57.8%) control patients. CONCLUSION: The prevalence of ventricular premature depolarization was similar for the chagasic and control groups during and after pregnancy. The incidence of supraventricular premature depolarizations was similar in the two groups during pregnancy, while after delivery a predominance was observed in the control group compared to the chagasic group.

Epidemiological aspects of adherence to the treatment of hypertension

OBJECTIVE: To analyze the reasons given by patients for interrupting their pharmacological treatment of hypertension. METHODS: We carried out an observational cross-sectional study, in which a questionnaire was applied and blood pressure was measured in 401 patients in different centers of the state of Bahia. The patients selected had been diagnosed with hypertension and were not on antihypertensive treatment for at least 60 days. Clinical and epidemiological characteristics of the groups were analyzed. RESULTS: Of the 401 patients, 58.4% were females, 55.6% of whom white; 60.5% of the males were white. The major reasons alleged for not adhering to treatment were as follows (for males and females respectively): normalization of blood pressure (41.3% and 42.3%); side effects of the medications (31.7% and 24.8%); forgetting to use the medication (25.2% and 20.1%); cost of medication (21.6% and 20.1%); fear of mixing alcohol and medication (23.4% and 3.8%); ignoring the need for continuing the treatment (15% and 21.8%); use of an alternative treatment (11.4% and 17.1%); fear of intoxication (9.6% and 12.4%); fear of hypotension (9.6% and 12%); and fear of mixing the medication with other drugs (8.4% and 6.1%). CONCLUSION: Our data suggest that most factors concerning the abandonment of the treatment of hypertension are related to lack of information, and that, despite the advancement in antihypertensive drugs, side effects still account for most abandonments of treatment.

Pregnancy and peripartum cardiomyopathy: a comparative and prospective study

OBJECTIVE: To assess pregnancy outcome in women with peripartum cardiomyopathy and to compare it with idiopathic cardiomyopathy. METHODS: Twenty-six pregnant women, aged 28.4±6.1 years, with dilated cardiomyopathy were followed. Eighteen patients had peripartum cardiomyopathy [11 with persistent left ventricular systolic dysfunction (EF=45.2±2) and 7 with recovered ventricular function (EF=62.3±3.6)]. The 8 remaining patients had idiopathic cardiomyopathy (EF= 43.5±4.1). During the prenatal period, limited physical activity and a low-sodium diet were recommended, and hospitalization was recommended when complications occurred. RESULTS: Of the 26 patients, 11 (42.3%) had a normal delivery; 9(35.5%) had cardiac complications, 6 (22.2%) had obstetric complications. Two patients (7.7%) died. Two preterm pregnancies occurred, with 26 health newborns (2 sets of twins). Two miscarriages took place. The cardiac complication rate during pregnancy was lower (p<0.009) in the peripartum cardiomyopathy group without ventricular dysfunction and greater (p=0.01) in the idiopathic group when compared with the peripartum group with ventricular dysfunction. Changes in left ventricular ejection fraction were not observed (p<0.05) in the postpartum period, when compared with that during pregnancy in the 3 groups. CONCLUSION: Pregnancy in patients with dilated cardiomyopathy is associated with maternal morbidity. Left ventricular function is a prognostic factor and must be the most parameter when counseling patients with peripartum cardiomyopathy about a new pregnancy.

Socioeconomic aspects of spousal concordance for hypertension, obesity, and smoking in a community of Rio de Janeiro, Brazil

OBJECTIVE: The present study aims to evaluate the environmental role in the distribution of hypertension, obesity, and smoking and spousal concordance for the presence/absence of these 3 cardiovascular risk factors. METHODS: A cross-sectional study was conducted in a community in Rio de Janeiro, Brazil. The households were randomly selected. Odds ratios were estimated to measure spousal concordance, across socioeconomic levels.. RESULTS: Overall a significant aggregation of all 3 risk factors was present. The crude odds ratio for hypertension was 1.78 (95%CI=1.02-3.08); for obesity, it was 1.80 (95%CI=1.09-2.96); and for smoking, it was 3.40 (95% CI=2.07-5.61). The spousal concordance for hypertension decreased significantly (p<0.001) from the lower to the higher educational level. In the case of obesity and smoking, the opposite was observed, although p-values for the linear trend were 0.10 and 0.08, respectively. CONCLUSION: In lower socioeconomic levels, couples are more concordant for hypertension and discordant for smoking. For hypertension and smoking, education seems to be a discriminant stronger than income, but for obesity the 2 socioeconomic indicators seem to represent different aspects of the environmental determinants of risk factor distribution.

Filososofía y Ciencia Computacional: Aspectos epistemológicos, ontológicos y metodológicos. Philosophy and Computing Sciencs: Epistemological, Ontological and Methodological Aspects.

Uno de los temas centrales del proyecto concierne la naturaleza de la ciencia de la computación. La reciente aparición de esta disciplina sumada a su origen híbrido como ciencia formal y disciplina tecnológica hace que su caracterización aún no esté completa y menos aún acordada entre los científicos del área. En el trabajo Three paradigms of Computer Science de A. Eden, se presentan tres posiciones admitidamente exageradas acerca de como entender tanto el objeto de estudio (ontología) como los métodos de trabajo (metodología) y la estructura de la teoría y las justificaciones del conocimiento informático (epistemología): La llamada racionalista, la cual se basa en la idea de que los programas son fórmulas lógicas y que la forma de trabajo es deductiva, la tecnocrática que presenta a la ciencia computacional como una disciplina ingenieril y la ahi llamada científica, la cual asimilaría a la computación a las ciencias empíricas. Algunos de los problemas de ciencia de la computación están relacionados con cuestiones de filosofía de la matemática, en particular la relación entre las entidades abstractas y el mundo. Sin embargo, el carácter prescriptivo de los axiomas y teoremas de las teorías de la programación puede permitir interpretaciones alternativas y cuestionaría fuertemente la posibilidad de pensar a la ciencia de la computación como una ciencia empírica, al menos en el sentido tradicional. Por otro lado, es posible que el tipo de análisis aplicado a las ciencias de la computación propuesto en este proyecto aporte nuevas ideas para pensar problemas de filosofía de la matemática. Un ejemplo de estos posibles aportes puede verse en el trabajo de Arkoudas Computers, Justi?cation, and Mathematical Knowledge el cual echa nueva luz al problema del significado de las demostraciones matemáticas.Los objetivos del proyecto son: Caracterizar el campo de las ciencias de la computación.Evaluar los fundamentos ontológicos, epistemológicos y metodológicos de la ciencia de la computación actual.Analizar las relaciones entre las diferentes perspectivas heurísticas y epistémicas y las practicas de la programación.

Aspectos moleculares del desarrollo de biofilms, la colonización de la planta y la emisión de compuestos orgánicos volátiles en bacterias rizosféricas. Molecular aspects of biofilm development, plant colonization and microbial volatile organic emission in rhizospheric bacteria.

Las bacterias que habitan la rizosfera y que poseen la capacidad de provocar un efecto positivo sobre las plantas son denominadas en su conjunto como Rizobacterias Promotoras del Crecimiento Vegetal (PGPR). Estas bacterias han desarrollado diferentes estrategias para adaptarse a diversas condiciones ambientales. La capacidad para responder a variaciones en la disponibilidad nutricional permite la persistencia de la bacteria en el suelo y mejora sus posibilidades para colonizar la planta hospedadora. En la naturaleza, a menudo las bacterias se encuentran en estructuras de comunidades de microorganismos interconectados denominados biofilms, con un estilo de vida diferente al de la vida en forma planctónica. La formación del biofilm podría representar una estrategia de supervivencia de la rizobacteria a condiciones adversas del suelo. Por Microscopía Confocal de Barrido Láser (CLSM), hemos observado que Rhizobium leguminosarum desarrolla un biofilm característico sobre una superficie abiótica. Hemos identificado algunos de los factores genéticos que influyen en su formación. El presente proyecto propone avanzar en el conocimiento de los factores ambientales y genéticos que influyen sobre la capacidad de las rizobacterias para formar biofilms y su impacto en la interacción con las plantas. A través de enfoques genéticos (mutacionales y de expresión génica) y análisis por CLSM nos proponemos acercarnos a un modelo de los factores de superficie, extracelulares y regulatorios propios de la bacteria que influyen en las propiedades de adhesión y la formación de biofilms. Por último, se intentará correlacionar la emisión de compuestos orgánicos volátiles por las bacterias rizosféricas con ciertos aspectos de la promoción del crecimiento de las plantas.

Aspectos bioquímicos y celulares de la reproducción de los vectores de la enfermedad de Chagas: regulación e importancia fisiológica. Biochemical and cellular aspects of the reproduction of Chagas’ disease vectors: regulation and physiologycal impact

En la hipótesis de trabajo del presente proyecto se considera la importancia del metabolismo de lípidos y proteínas en los insectos hematófagos, en particular en los vectores de la enfermedad de Chagas, para afrontar exitosamente la demanda energética de la reproducción. Las hembras de estas especies pueden ingerir una comida de sangre abundante en lípidos y proteínas, los que son modificados en el intestino para su utilización y posterior almacenamiento en estructuras organizadas en el tejido ovárico, sustentando así el rápido crecimiento de los ovocitos. Estos aspectos resultan críticos para el ciclo de vida del insecto y para el mantenimiento de la cadena epidemiológica de la enfermedad. En estas especies, recientemente hemos caracterizado a nivel bioquímico y celular la interacción entre lipoproteínas y tejidos [Fruttero y col., Insect Biochem. Mol. Biol. 39: 322-331 (2009); Fruttero y col. Biocel 33 (3): 260 (2009)] y las fases del ciclo reproductivo [Aguirre y col., J. Insect Physiol. 54: 393-402 (2008)]. No obstante, los factores que participan en su regulación son aún escasamente conocidos. En este contexto, el estudio propone emplear dos especies de triatominos con el objeto de: (1) caracterizar los factores involucrados en la formación y regulación de reservas nutricionales en los ovocitos; (2) analizar los eventos que participan en la regresión del tejido ovárico: atresia folicular y mecanismos de muerte celular. (3) evaluar el impacto de productos naturales (ureasas vegetales y péptidos derivados) en el desarrollo del tejido ovárico. Para la ejecución de los objetivos se llevarán a cabo ensayos in vivo e in vitro con trazadores fluorescentes, fraccionamiento subcelular, estudios de expresión de proteínas (mRNA y proteína), estudios histo-morfológicos, ultraestructurales e inmunocitoquímicos, microscopía láser confocalizada, ensayos de actividad enzimática, ELISA, western-blot, electroforesis bidimensional, espectrometria de masas en tándem, etc. También se evaluarán los mecanismos de muerte celular (apoptosis/autofagia) mediante microscopía electrónica, detección de apoptosis in situ (TUNEL), inmunofluorescencia, etc. Los resultados obtenidos permitirán un mejor conocimiento sobre la fisiología y bioquímica de estos vectores, los que resultan indispensables en el diseño de nuevas estrategias para su control. Debido a la carencia de un tratamiento específico para la enfermedad y a la falta de métodos preventivos (vacuna), el control del vector es una de las vías más importantes para reducir la incidencia de la enfermedad. Actualmente, la situación socio-económica que sufren amplios núcleos de nuestra población propicia condiciones de vida que facilitan la reproducción de los vectores y la transmisión vectorial del parásito. El estudio permitirá además explorar aspectos bioquímicos y celulares básicos, generando conocimientos que podrían ser extensivos a otros insectos de importancia económica en la ganadería y/o agricultura. The aim of this project is to analyze the biochemical and cellular events involved in the lipid and protein metabolism in Chagas' disease vectors, and to evaluate their impact on the physiology of reproduction, particularly in the formation of nutritional resources in developing oocytes. At present, little is known about these critical aspects for the life cycle of the insect and for the epidemiology of the disease. The experimental approaches, which will be carried out using two species of triatomines, were designed: (1) to characterize factors involved in the formation and regulation of nutritional resources in developing oocytes; (2) to analyze the biochemical and cellular events that play a role during the regression of ovarian tissue, including the processes of oocyte resorption and programmed cell death. (3) to evaluate the impact of natural products (ureases from jackbean and related peptides) in the development of ovarian tissue. Methods and techniques involved in the project are: in vivo and in vitro assays with fluorescent tracers, ELISA, chemical assays, enzyme activities, western-blot; protein expression (mRNA), histological techniques, immunohistochemical and ultrastructural studies. Cell death will be analyzed by detection of apoptosis in situ (TUNEL), immunofluorescence (for autophagy), among others. The results obtained from the study will offer the opportunity to explore important aspects in the biology and physiology of Chagas' disease vectors that could be of potential utility in designing alternative strategies for the control of the insect.
