Full textWe have developed a new approach to determine parton distribution functions and quantify their experimental uncertainties, based on Markov Chain Monte Carlo methods.The main interest devoted to such a study is that we can replace the standard χ 2 MINUIT minimization by procedures grounded on Statistical Methods, and on Bayesian inference in particular, thus offering additional insight into the rich field of PDFs determination.After reviewing these Markov chain Monte Carlo techniques, we introduce the algorithm we have chosen to implement – namely Hybrid (or Hamiltonian) Monte Carlo. This algorithm, initially developed for lattice quantum chromodynamique, turns out to be very interesting when applied to parton distribution functions determination by global analyses ; we have shown that it allows to circumvent the technical difficulties due to the high dimensionality of the problem, in particular concerning the acceptance rate. The feasibility study performed and presented in this thesis, indicates that Markov chain Monte Carlo method can successfully be applied to the extraction of PDFs and of their experimental uncertainties

Abstract: Objectives: To validate Grobman’s model to predict the success of vaginal delivery after a prior cesarean delivery at an University Hospital of São Paulo state and test the accuracy and calibration of the model in this population Methods: This is a retrospective cohort study of parturient women with a previous cesarean section, with single management, one term, with live and cephalic presentation, with no period between 2013 and 2015, attended at a maternity hospital in a university hospital in the State of São Paulo. Paulo. As variables used to validate the Grobman model, they were used in electronic medical records, inserted in the formula and observed with success rate in the predator or vaginal delivery after cesarean section (PVPC) for each parturient. As prediction rates, they were divided into decisions and compared with observed rates. The calibration test was performed through the intercept and slope; The cut-off point for the PVPC success rate predator was used by the ROC curve, being calculated with precision - using the statistical program SPSS for Windows. Results: 416 parturients were evaluated and the success rate of vaginal delivery after cesarean section was 53.8%. The calibration test was performed using the Slope and Intercept to compare the rates. The area under the curve of the Grobman model was 0.71 (sensitivity and specificity of 70%).

Nesse estudo, discutimos o modelo de assistência ao parto – o parto humanizado, analisando tanto fatores que possibilitam quanto os que dificultam sua implementação e como é promovido pelo Programa Rede Cegonha do governo federal. Nossa metodologia consiste em levantamento bibliográfico, análise documental de materiais relativos à humanização da assistência ao parto, do programa Rede Cegonha, do Guia de Assistência ao Parto Normal, publicado pela Organização Mundial da Saúde, e documentos públicos e privados relativos a tais temas; além de entrevistas qualitativas com acadêmicos e gestores no que diz respeito à assistência ao parto e à Rede Cegonha. No Brasil, se de um lado há condições que possibilitam o parto humanizado – movimento de mulheres, inserção de equipe multidisciplinar na assistência ao parto, mudança em estruturas físicas de maternidades, observância das recomendações da Organização Mundial de Saúde quanto à assistência ao parto normal e gestores comprometidos com o modelo, de outro, existem fatores que o dificultam, como o modelo de atenção intervencionista, medicalizado e médico-centrado. Os resultados de nossa pesquisa sugerem que, embora passível de críticas, a Rede Cegonha se mostra como um facilitador na adoção do parto humanizado – um modelo ainda em construção e que exige amplo debate.
In this study we discussed the childbirth assistance model – the humanized childbirth, analyzing both factors that make possible and those that hinder its implementation and how it is promoted by the 'Rede Cegonha' Program of the federal Government in Brazil. Our methodology consists of bibliographic analysis, documentary analysis of materials concerning the humanization of birth assistance, 'Rede Cegonha' Program, the document 'Care in Normal Birth: a practical guide', published by the World Health Organization, and public and private documents relating to those themes; in addition to qualitative interviews with academics and managers about childbirth assistance and the 'Rede Cegonha'. In Brazil, if there are conditions that allow the humanized childbirth assistance – like women's movement, insertion of a multidisciplinary team in the childbirth assistance, change in physical structures of maternities, compliance with the recommendations of the World Health Organization related to the normal childbirth and managers committed to the model - on the other hand there are factors that make it difficult, as the interventionist, medicalized attention and physician-centered childbirth assistance model. The results of our study suggest that, although liable to critics, the 'Rede Cegonha' Program shows itself as a facilitator in the adoption of Humanized childbirth – a model still under construction and that requires wide-ranging debate.

Full textEn Chile el modelo de atención de los procesos reproductivos posee un carácter predominantemente tecnocrático, privilegiando una mirada patológica sobre la gestación y el parto. Lo anterior produce un actuar obstétrico basado en la repetición de intervenciones rutinarias no justificadas medicamente con poca o nula evidencia científica que las respalde. La mayoría de las veces, estas intervenciones constituyen un daño para la salud de la madre y el/la recién nacido/a tanto a corto como a largo plazo. Un ejemplo paradigmático de estas intervenciones es la cesárea, que en salud privada asciende a un 71,8% excediendo ampliamente el límite de 15% recomendado por la Organización Mundial de la Salud (OMS). Las explicaciones médicas justifican en parte este porcentaje en el deseo de las mujeres, sin embargo, la mayoría tiene una preferencia explícita por el parto por vía vaginal y en el caso de la salud privada esto se vuelve relevante, ya que las mismas poseen la facultad de elegir ciertos elementos y condiciones de su atención. Este alto nivel de intervención y el actuar en contra de las preferencias de las usuarias por parte del personal de salud, responde a condiciones culturales del actual modelo de atención. En orden de aportar a describir estas condiciones exploramos las representaciones en torno al cuerpo gestante y las vías de parto en mujeres gestantes y puérperas del sistema de salud privado de la Región Metropolitana y cómo estas influyen en el proceso de toma de decisiones respecto al parto. Las principales representaciones sobre el cuerpo gestante y las vías de parto que se producen en las interacciones entre usuarias, personal de salud y entorno social a lo largo de la gestación objetifican al cuerpo gestante como un medio y destacan su carácter potencialmente patológico. Además el carácter paternalista de las relaciones que se producen con los/as obstetras sitúan a las mujeres en una posición secundaria y despojada de poder. Si bien el parto por vía vaginal es preferido por las usuarias a nivel explícito, las representaciones existentes en torno a él, como más doloroso, sufriente y más riesgoso generan inseguridades, temores e incertidumbres a su alrededor. De esta forma las intervenciones obstétricas se instalan como herramientas apropiadas para controlar y reparar potenciales patologías. Lo anterior a través de la entrega de información no basada en evidencia por parte del personal de salud y de la culpabilización constante hacia los cuerpos de las mujeres. Esta forma de atención termina por convencer o directamente obligar a las mujeres a tomar decisiones en contra de sus preferencias iniciales, instalando la idea de que fueron ellas quienes eligieron la forma de atención que recibieron (lógica de la elección)

Milk samples were collected and evaluated blood where blood count, neutrophil oxidative metabolism (NBT), immunoglobulins, biochemistry, and CMT, somatic cell count, microbológico isolation of colostrum and milk and milk immunoglobulins in the 60 days preceding childbirth (M1) on the day of delivery (M2), three, seven, 15, 21, 30 days postpartum (M3, M4, M5, M6 and M7). Data were analyzed by the software Stata using a logistic regression model. The variables were analyzed individually to check the meaning and then, in combination, to evaluate the effect of individual variables. In the first phase of the analysis, logistic model was used for each variable related to the clinical findings, with P values less than 0.20 were considered as a variable selected and passed to the next stage of analysis. In the final model, selected variables were used in the first phase to develop a multivariate logistic model in which the variables with P ≤ 0.05 were retained in the final model. It was possible to identify changes in the parameters, protein, albumin and Fibrinogen, serve as biomarkers associated with Bovine Mastitis. Specific metabolic changes and characteristics of the transitional period, blood parameters, overlapping the effect of drying employees and protocols, it is suggested that the systemic profile the periparto cow is associated with mastitis

Introdução: A depressão tem etiologia multifatorial, atingindo um significativo número de mulheres no pós-parto com estimativas de prevalência entre 7,2% à 39,4%. Especialistas em saúde materna têm encontrado associação positiva dos distúrbios psiquiátricos do período puerperal, inclusive depressão, com experiências negativas associadas à atenção obstétrica. Várias categorias de violência na atenção obstétrica têm sido utilizadas para análise dessa condição, como aquelas da Organização Mundial da Saúde ou aquelas, recentemente, propostas pela Escola de Saúde Pública de Harvard, nos Estados Unidos. No entanto, nenhuma dessas categorias contempla dimensões mais amplas da atenção obstétrica como às relacionadas ao Sistema de Saúde e aos Serviços de saúde. O presente estudo propõe uma nova categorização da violência institucional na atenção obstétrica e busca sua associação com depressão pós-parto. Métodos: Revisão da literatura científica a partir de uma pesquisa nos bancos de dados Scopus, análise de artigos que se encontravam nas referências bibliográficas das fontes indexadas e livros e teses sobre violência institucional na atenção obstétrica. Organizou-se os artigos em categorias, tendo como base um modelo conceitual de qualidade de cuidado a partos e nascimentos. Criou-se indicadores de violência institucional na atenção obstétrica e construiu-se um modelo de regressão logística, a fim de buscar a associação entre violência com depressão pós-parto. Resultados: Identificou-se uma alta prevalência de depressão pós-parto, sendo maior em mulheres adolescentes e de raça não branca, e uma forte associação positiva entre os diversos indicadores de violência na atenção obstétrica com depressão pós-parto. Observou-se, também, interação positiva em escala multiplicativa da violência profissional por negligência com raça e com idade, da violência profissional física com idade e da violência profissional verbal com raça. Conclusão: A partir dos resultados dessa investigação, conclui-se que os indicadores utilizados para refletir a violência institucional na atenção obstétrica mostraram-se positivamente associados à depressão pós-parto o que nos leva a refletir sobre a necessidade de mudanças de atitude destes profissionais e que estas atendam aos preceitos da política de humanização. ______________________________________________________________________________ ABSTRACT
Introduction: Depression has a multifactorial etiology, affecting a significant number of women postpartum. Estimates of prevalence of postpartum depression are under7.2% to 39.4%. Maternal health experts have found a positive association between psychiatric disorders postpartum period, including depression, and negative experiences associated with obstetric care. Several categories of violence in obstetric care have been used for analysis, such as those of the World Health Organization and those, recently, proposed by the USAID-Traction Project, Harvard School of Public Health, in the United States. However, none of them have includedbroader dimensions of obstetric care as those related to the Health System and to the Health Services. This study proposes a new categorization of institutional violence in obstetrics and seeks its association with postpartum depression. Methods: Review of the scientific literature from a survey of banks in Scopus data, and analysis of articles that were indexed in the bibliography of sources, besides books and thesis on institutional violence in obstetric care, were used. The articles were organized into three categories, based on a conceptual model of quality of care in labor and delivery, where the interactions between them, users, professionals, institutions and society influence care. Indicators of institutional violence in obstetrics were created and a logistic regression model was built, in order to seek an association between violence and postpartum depression. Results: The model identified a higher prevalence of postpartum depression among adolescent women and non-white race, and a strong positive association between several indicators of violence in obstetric care with postpartum depression. It was, also, observed apositive interaction on a multiplicative scale, between violence by professional negligence with race and age, professional physical violence with age and verbal violence with professional race. Conclusion: The indicators used to reflect the institutional violence in obstetrics proved to be positively associated with postpartum depression, which leads to a reflection on the needs for adequacy of obstetric care to the precepts of humanization policies.

Full textIn this paper we consider Gerber-Shiu discounted penalty function in the classical risk model for Pareto claims. Our main goal is to construct an algorithm for obtaining values of the discounted penalty function (considering penalty function w=1). Due to the complicated form of the transformed Pareto distribution function we cannot obtain its convolutions analiticaly. We use numerical methods provided by Maple (cube spline) to find interpolating functions instead. Continuously applying recursive formulas we obtain first 5 interpolated convolutions. Then we calculate values of Gerber-Shiu discounted penalty function for certain arbitrary parameters: α – degree of Pareto distribution function, initial surplus u, security loading θ, discounting parameter δ and Poison process parameter λ. We present data tables and graphs of the discounted penalty function for some variations of parameters in later sections. Finally we state that the method that we use is quite complicated. For better accuracy of the discounted penalty function values one may require to get many convolutions of the transformed Pareto distribution function and that may require too great of the resources. However the quantity of the convolutions needed rapidly decreases for large values of the initial surplus u.

Full textThe main topic of this thesis is the study of nuclear effects in Drell–Yan dilepton production at RHIC and LHC energies. Two approaches are employed: the color dipole approach and the parton model with intrinsic transverse momentum. In the first chapter, a brief introduction and the motivation to the study are presented. Chapt. 2 reviews the deep inelastic scattering (DIS) in the parton model and the parton distribution functions of protons (CTEQ) and of nucleons (EKS, EPS08 e EPS09) are examinated. The DIS in the dipole frame is also discussed. Chapt. 3 reviews the theoretical foundations of the color dipole approach and the dipole cross section. The main equations that drive the dipole evolution are shown, followed by the phenomenological parameterizations GBW, DHJ, BUW, and ABGS. A new model is proposed: the AGBS parameterization with fluctuations. When fitted to HERA data, the new parameterization does not differ from the old AGBS, indicating that fluctuations are not needed to reproduce DIS data at current energies. Chapt. 4 discusses the parton model in the Drell–Yan process. This approach is considered at leading order, at next-to-leading order (NLO), and at NLO with intrinsic transverse momentum, as only in the last case the dilepton transverse momentum distribution can be obtained in agreement with experiments. Afterwards, the color dipole approach applied to the process is examined, giving at leading order a transverse momentum distribution compatible with experiments. The results are calculations to the nuclear modification factor (RpA) at backward rapidities as function of rapidity and transverse momentum. The use of backward rapidities of the color dipole approach is an original contribution, as well as the comparison of this approach with the parton model with intrinsic transverse momentum. Effects of large (EMC effect and antishadowing) and of small x (shadowing) are seen. It is shown that the intrinsic transverse momentum is particularly important, changing the nuclear modification factor of about 10%. When different parameterizations of the dipole cross section are compared, the dilepton production does not show significant discrepancies, suggesting the it is not sensitive to the parametrization details, such as the possibility of geometric scaling breaking present in DHJ parameterization. Furthermore, the parton model results are extended to forward rapidities and compared with results of the color glass condensate. At RHIC energies, the approaches agree, while at LHC energies, unless the nuclear parameterization shows a very strong nuclear shadowing (EPS08 case), the approaches disagree, due to the different behaviors of gluon shadowing and quark shadowing. The unidimensional model, a toy model of the dipole evolution that includes the fluctuation effects is also investigated. Specificaly, the possibilities of geometric scaling and difusive scaling in cross sections are discussed.

O cuidado do enfermeiro obstetra no parto no Estado do Rio Grande do Norte tem fomentado inquietações no que diz respeito à plena efetivação do profissional nas fases dos processos de nascimento, bem como quanto às dificuldades existentes nessa atuação. Assim, a pesquisa objetivou Compreender as práticas de cuidado do enfermeiro à mulher no parto hospitalar a partir dos significados atribuídos por esses profissionais no Estado do Rio Grande do Norte; e Elaborar modelo teórico das práticas de cuidado do enfermeiro obstetra à mulher no parto hospitalar. Foi utilizado o referencial metodológico da Teoria Fundamentada nos Dados (Grounded Theory), sendo realizada a análise dos dados, de acordo com os pressupostos do método, até a fase final da construção do modelo paradigmático: Configurando o modelo da prática do cuidado do enfermeiro obstetra à mulher no parto hospitalar: revelando contradições e possibilidades. O referencial teórico foi o paradigma da complexidade. A pesquisa se realizou nos hospitais/maternidades que tinham a atuação do enfermeiro obstetra e que possuíam histórico de humanização da assistência. Dessa maneira, cinco maternidades compuseram o estudo e outras duas estavam em reforma no período da coleta, que aconteceu nos meses entre fevereiro e outubro de 2014, após aprovação no Comitê de Ética em Pesquisa da Universidade Federal de Santa Catarina, segundo o Parecer 507.327. Foram entrevistados 16 enfermeiros obstetras que compuseram o primeiro grupo amostral. Posteriormente foi necessária a formação do segundo grupo amostral, composto por oito gestores de saúde e diretores de maternidades, e do terceiro grupo amostral, composto por sete médicos. Os dois últimos foram acrescidos devido ao aparecimento de hipóteses e para esclarecer e refinar os conceitos que surgiram na fase de análise. Realizaram-se entrevistas individuais por meio de um roteiro de entrevista aberta, gravadas em mp3 e armazenadas em computador, em local que garantisse a privacidade e confidencialidade do entrevistado. Na sequência de cada entrevista foram realizadas as transcrições. As entrevistas então foram cessadas a partir do momento em que as categorias estavam densas em suas propriedades e dimensões e não existiam mais dados novos a serem explorados. A análise dos dados ocorreu simultaneamente à coleta, mediante comparações constantes. A análise iniciou pela microanálise, palavra por palavra, linha por linha, frase por frase. A codificação aberta caracterizou-se pela decomposição, análise, comparação, conceituação e categorização. A codificação axial caracterizou-se por relacionar categorias às subcategorias em torno de um eixo central, ou áxis. A codificação seletiva oportunizou o surgimento da categoria central e a relação das categorias mais gerais. Foram construídos memorandos e diagramas que auxiliaram no processo de análise. Assim, após o surgimento das categorias mais gerais foi construído o modelo paradigmático, embasado nas interações e relações, no que diz respeito ao contexto, às condições causais, às condições intervenientes, às ações/interações estratégicas e consequências. A primeira categoria  Vivenciando os cenários de prática do enfermeiro obstetra no Estado do Rio Grande do Norte: dos limites históricos a eventos contemporâneos  representa o contexto do fenômeno. A segunda categoria  Emergindo condições que favorecem a consolidação da enfermagem obstétrica: perspectivas e desafios  retrata os fatos que interferem no fenômeno, que são: a formação dos enfermeiros, as interações e relações que o enfermeiro constrói, a partir de sua prática e a gestão de saúde e de maternidades. A terceira categoria  Vivenciando as desordens na prática do cuidado do enfermeiro obstetra no parto: o olhar complexo ao fenômeno  representa as dificuldades encontradas pelo profissional em sua atuação, caracterizadas como condições intervenientes. A quarta categoria  Construindo estratégias para o fortalecimento da enfermagem obstétrica do Rio Grande do Norte, na perspectiva dos sistemas complexos adaptativos  discorre sobre as ações/interações estratégicas para a melhoria do fenômeno. A quinta categoria  Revelando contradições e possibilidades na prática profissional do enfermeiro obstetra  é a categoria central, que integra as outras categorias gerais e representa as consequências do fenômeno. Aponta a atuação do enfermeiro no cuidado ao parto, identificando as possibilidades e contradições existentes. Assim, a abstração dos conceitos, a relação das categorias e a elaboração do paradigma de análise sustentam a tese: A prática de cuidado do enfermeiro obstetra à mulher no parto hospitalar configura-se como um modelo de cuidado integral, complexo, relacional, humanizado e ético orientado pelas políticas públicas e evidências científicas atuais, com ênfase no protagonismo e empoderamento feminino. É necessário superar as dificuldades de formação, a falta de autonomia, a hegemonia médica, a violência obstétrica...
Abstract : The childbirth care provided by obstetric nurses in the state of Rio Grande do Norte has fostered concerns regarding their full participation in birth process phases, along with its inherent difficulties. Thus, this study aimed to understand nursing care practices for women in hospital deliveries from the meanings attributed by these professionals in the State of Rio Grande do Norte and to elaborate a theoretical model for obstetric nursing care practice for women in hospital births. The Grounded Theory methodological framework was used to analyse the data, according to the method assumptions, up until the final construction stage of the paradigmatic model: Configuring the model of obstetric nurse care practices for women in hospital births: revealing contradictions and possibilities. The theoretical framework was the paradigm of complexity. The survey was conducted in hospitals/maternity hospitals with obstetric nurses and with a history of healthcare humanization. Consequently, the study comprised five hospitals, while two others were under renovation during the collection period, which took place in the months from February to October 2014, after approval by the Ethics Committee of the Federal University of Santa Catarina, in opinion no. 507,327. 16 obstetric nurses were interviewed, which composed the first sample group. It was later necessary to form a second sample group, consisting of eight healthcare administrators and maternity hospital directors, and a third sample group, composed of seven doctors. The last two were added because of the appearance of hypotheses and to clarify and refine the concepts that emerged in the analysis phase. Individual interviews were conducted through an open interview, recorded on .mp3 and stored on a computer, in a place that could guarantee respondents privacy and confidentiality. Transcripts were made in sequence. Interviews stopped from the moment the categories became dense in their properties and dimensions, and there was no new data to be further explored. Data collection and analysis occurred simultaneously, with constant comparisons taking place. The analysis began by microanalysis, word by word, line by line, sentence by sentence. Open coding was characterized by decomposition, analysis, comparison, conceptualization and categorization. Axial coding was characterized by relating categories to sub-categories around an axis or central axis. The selective coding provided an opportunity for the emergence of the core category and a list of more general categories. Memos and diagrams that helped in the analysis process were constructed. Thus, after the appearance of more general categories, the paradigmatic model was built, based on the interactions and relationships, regarding context, causal conditions, intervening conditions, strategic actions/interactions and consequences. The first category  Experiencing obstetric nurse practice scenarios in the state of Rio Grande do Norte: from historical limits to contemporary events  represents the phenomenon s context. The second category  Emerging conditions for the consolidation of obstetric nursing: prospects and challenges  portrays the events that affect the phenomenon, which are: nurses training, interactions and relationships built from their practice and healthcare and maternity hospital management. The third category  Experiencing disorders in obstetric nursing care practice in births: the complex phenomenon aspect  represents the difficulties faced by professionals in their field, characterized as intervening conditions. The fourth category  Building strategies for strengthening Rio Grande do Norte obstetric nursing in the perspective of complex adaptive systems  discusses the actions/strategic interactions to improve the phenomenon. The fifth category  Revealing contradictions and possibilities in the professional practice of obstetric nurses  is the central category that integrates the other general categories and represents the phenomenon s consequences. It points to the work of nurses in obstetric care, identifying the existing possibilities and contradictions. Thus, the concepts abstraction, the list of categories and the analysis paradigm elaboration support the thesis: The obstetric nurse care practice for women in hospital births configures a comprehensive, complex, relational, humane and ethical care model guided by public policies and current scientific evidence, with emphasis on women s leadership and empowerment. It is necessary to overcome training difficulties, lack of autonomy, doctor s hegemony, obstetric violence and the difficulty in the management processes to qualify obstetric care on the part of the obstetric nurse.

Full textAproximadamente 0,8% das mulheres em território português tem seus filhos fora do ambiente hospitalar (Pordata, 2019). As mulheres e famílias que optam por um parto domiciliar planeado (PDP) enfrentam muitas dificuldades e obstáculos. Este estudo descreve as principais razões e motivos que levam as famílias a optarem pelo ambiente domiciliar para o nascimento de seus bebês, bem como o impacto dessa escolha na vida pessoal e familiar. Para que fosse possível conhecer os fatores subjetivos à escolha do PDP, a técnica de recolha de dados utilizada foi a entrevista semiestruturada, realizada, separadamente, à mulher e ao seu parceiro. Realizaram-se um total de 16 entrevistas, das quais: 10 mulheres, 5 homens e 1 Enfermeira Especialista de Saúde Materna e Obstétrica. Tendo em vista a escolha pela não participação de alguns homens, somente as entrevistas onde os 5 homens e 5 mulheres que participaram da gestação e do parto dos mesmos filhos, foram descritos e tiveram os dados analisados. O trabalho de Guerra (2006) foi utilizado como norteador para a escolha da metodologia de análise de dados, que recaiu sobre uma Postura Analítica e Reconstrução do sentido. Todo o material recolhido na pesquisa foi sujeito a Análise de Conteúdo, no intuito de descrever situações e interpretar o sentido social. Foi realizada uma Análise Descritiva Temática aprofundada, onde os corpus centrais das entrevistas foram identificados permitindo a identificação de categorias e subcategorias com base no conteúdo das entrevistas e nos achados teóricos. Três caterorias foram identificadas como centrais para a escolha do PDP: (I) Autonomia (i. Capacidade de escolha; ii. Informações de Qualidade; iii. Liberdade); (II) Razões (i. Percepção de Segurança; ii. Evitar Interveções; iii. Experiências Hospitalares Anteriores; iv. Maior Controle do Processo; v. Ambiente Familiar; e vi. Conhecimento dos Modelos Obstétricos); (III) Implicações da escolha (i. estigmatização; ii. Conflitos Internos; iii. Conflitos entre os membros do casal; iv. Aspectos financeiros; v. Parto Idealizado X Parto Real). O estudo termina com a reflexção crítica sobre esta prática e as escolhas nesse domínio, incluindo questões de género, e propostas de investigações futuras.
Approximately 0.8% of women in Portuguese territory have their children outside the hospital environment (Pordata, 2019). Women and families opting for planned home birth face many difficulties and obstacles. This study describes the main reasons that lead families to choose the home environment for the birth of their babies, as well as the impact of this choice on personal and family life. The data collection technique used to learn about the factors that influence the family’s choice of planed home birth, was the semi-structured interview, conducted separately with the women and their partners. A total of 16 interviews were conducted, of which: 10 women, 5 men and 1 Specialist Nurse of Maternal and Obstetric Health. Since some men choose not to participate in the interviews, only the interviews where the 5 men and 5 women who participated in the pregnancy and childbirth of the same children, were analyzed and were described in this dissertation. The theoretical-methodological stance adopted was the Analytical Stance and Sense Reconstruction. Guerra's work (2006) was used as a guide for choosing the data analysis methodology. All the material collected was submitted to an Analysis of Content, with the intention of describing situations and interpreting their social meaning. In the Thematic Descriptive Analysis, the central corpus of the in-depth interviews was analyzed making possible the identification of categories and subcategories. The categories and subcategories were created based on the content of the interviews and on the theoretical findings. Three main categories were identified as the main reasons for the PDP option: (I) Autonomy (Ability to choose; Quality information; Freedom); (II) Reasons (Perception of Security; Avoid Interventions; Previous Hospital Experiences; Greater Control of the Process; Family Environment; Knowledge of Obstetric Models); (III) Implications of the choice (Stigmatization; Internal Conflicts; Conflicts Between the Members of the Couple; Financial Aspects; Idealized Delivery versus Real Delivery). The study ends with a critical reflection on this practice and the choices in this area, including gender issues and proposals for future research.

Silibinina é um flavonóide quimicamente definido e o principal componente ativo da silimarina, um complexo polifenólico obtido de frutos e sementes de Silybum marianum, que possui propriedades anti-inflamatória, hepatoprotetora e anti-carcinogênica. Objetivo: O objetivo deste trabalho foi avaliar os efeitos da silibinina sobre a performance reprodutiva de ratas prenhes Wistar e as anomalias e/ou malformações de seus fetos. Métodos: Foram utilizadas ratas Wistar prenhes estratificadas em quatro grupos experimentais: controle (n = 6), ratas tratadas com 50mg/kg/dia de silibinina (Grupo I, n = 6), ratas tratadas com 100mg/kg/dia de silibinina (Grupo II, n = 6) e ratas tratadas com 200mg/kg/dia de silibinina (Grupo III, n = 6). Os animais receberam tratamento por via oral (gavage). Durante toda a prenhez, o consumo de ração e a ingestão de água, bem como o ganho de peso corporal foram avaliados. No dia 21 de prenhez as ratas foram anestesiadas A cesárea foi realizada no 21º dia, quando os recém-nascidos foram mortos e processados para análise das variações e/ou malformações. Resultados: os grupos controle e tratados não apresentaram diferenças significativas em relação aos parâmetros fetais, não se observando sinais de toxicidade materna com as diferentes concentrações de silibinina empregadas. Conclusão: O tratamento com silibinina não determinou efeitos deletérios na performance reprodutiva das ratas, mesmo quando utilizada em altas doses (200 mg/Kg/dia).

Objective: The aim of the present study was to evaluate the dose-dependent effect of silibinin treatment on maternal reproductive performance and on abnormalities and/or fetal malformations. Methods: Pregnant Wistar rats were distributed in four experimental groups: control, not treated with silibinin (n=6), rats treated with silibinin 50mg/kg/day (Group I, n = 6), rats treated with silibinin 100mg/kg/day (Group II, n = 6) and rats treated with silibinin 200mg/kg/day (Group III, n = 6). Silibinin was administrated by gavage from day 0 to 20 of pregnancy. During the period of pregnancy food and water intake, as well as weight gain were evaluated. On day 21 of pregnancy, the rats were anesthetized and submitted to cesarean section to analyse maternal reproductive performance and fetal malformations. Results: The control and silibinin-treated groups did not show significant differences in relation to the fetal parameters evaluated and no maternal toxicity effects of silibinin were detected in the concentrations employed. Conclusion: Silibinin treatment did not determined deleterious effect on the maternal reproductive performance and fetal outcome even when employed in high dose (200 mg/Kg).

Place of study, Sant Joan de Déu Hospital in Barcelona, from October 2015 to February 2018. The sample was of 148 low-risk pregnant women. The main variables of the study were pain, perineal integrity and the Apgar test five minutes after birth. A univariate and bivariate analysis and logistic regression models were performed. Conclusions: There was a higher score of 10 in the Apgar test at five minutes in the natural childbirth model. The older you are, the more likely you are to have pain. Satisfaction with the birth process was greater in the medicalized delivery model but the usefulness of the birth plan was more useful in natural birth.

Full textIntimate partner violence (IPV) has been recognized as an important public health problem and a risk factor for health problems of women and children. Health services play an important role in early detection of IPV. This issue is especially important in moments of life when systematized care is recommended, such as the pregnancy and early childhood. The main objective of this research was to estimate the probability of physical intimate partners violence (PIPV) during pregnancy or postpartum period. This is a cross-sectional study carried out in 5 primary health care units in Rio de Janeiro during the year 2007. Eight hundred and eleven interviews with mothers of children up to five months of age were carried out. Mothers presenting any formal contraindication for breastfeeding were considered ineligible, as well as women not reporting at least one month of amorous relationship during the pregnancy or postpartum period. Socioeconomic, demographic and life habits of the couple were considered as potential predictors. The outcome variable was assessed at three levels: no PIPV; PIPV during the pregnancy or postpartum; and PIPV in both periods. A multinomial logit model was used for projecting the respective prevalence according to a range of selected descriptors. The risk factors significantly associated with a greater risk of PIPV were: maternal age < 20; women with less than twelve years of schooling; women with 2 or more children under five years old; alcohol misuse by mother or partner; illicit drug abuse by the women or partner; and mothers perception of infants health lower than expected. Between mothers with all those characteristics, the projected prevalence of PIPV during pregnancy and/or postpartum was 96.4%, and as much as 59.4% accounted for the occurrence in one of the periods and 37% for the occurrence in both periods. In the absence of all of those factors, estimates reached only 3.6% during pregnancy and/or postpartum Summarizing, this study disclosed that some characteristics of children and their family increases the probability of PIPV during the pregnancy and postpartum period. This information is valuable for achieving early identification and effective resolution of the problem.

Full textPostpartum affective disorders are rarely modeled. The depressive-like behavior of hormone withdrawal following hormone-simulated "pregnancy" was described in Long-Evans and Sprague Dawley rats. Our aim was to evaluate the validity of hormone withdrawal following hormonesimulated "pregnancy" method in Wistar rats as a model of depression and/or anxiety. Recently, it was demonstrated an antidepressant-like profile of methanol extract of Hibiscus tiliaceus L., a plant used in postpartum disorders, in adult male Swiss albino mice, then, we also investigated the antidepressant and anxiolytic-like activities of the methanol extract of H. tiliaceus flowers using this animal model of postpartum disorder. Ovariectomized rats received daily injections of the vehicle or hormones (estradiol and progesterone) to simulate the 23-day gestational period in the rat. Days 24-27 were considered the ''post-partum'' period, where the methanolic extract of H. tiliaceus or vehicle were administered by gavage. Rats were submitted to forced swimming, elevated plus-maze test and lightdark box tests. Rats submitted to ''post-partum depression model'' increased the immobility time in forced swimming. The methanolic extract of H. tiliaceus administration did not alter the immobility time in the forced swim test. In the light-dark box test, rats submitted to post-partum depression model showed decreases in number of rearing in dark compartment. In conclusion, our data indicate that Wistar rats may be an adequate model postpartum affective disorders, showing ''depressive-like'' symptoms in the forced swim test without any anxiogenic effect. Besides, we could suggest that decrease on number of rearing in the dark compartment may indicate the motivational state.

Full textIn this PhD thesis we investigate several aspects of parton distribution functions (PDFs) and jets as applicable to the physics underpinning the Large Hadron Collider (LHC) as well as future colliders. We first discuss jet observables at the LHC, focusing on the single-jet inclusive cross section. We introduce possible alternative definitions, which weigh the individual contributions coming from each jet in the event and are thus unitary by construction. We also clarify the origin of some problematic aspects of the standard definition. Secondly, within the hadronic PDF fitting framework of the NNPDF collaboration, we investigate the inclusion of single-jet inclusive and dijet measurements into a global PDF fit, using QCD next-to-next-to-leading order predictions for jet processes. We field-test which observables lead to better perturbative stability, better PDF compatibility with other data, better fit quality, and more stringent constraints on the PDFs. Thirdly, we focus on an analytical understanding of machine learning techniques used for quark versus gluon discrimination, a hot topic in jet substructure studies. We construct a new version of the widely used N-subjettiness variable, which features a simpler theoretical behaviour than the original one, while maintaining, if not exceeding, the discriminating power. We input these new observables to the simplest possible neural network, with only one neuron, and we study analytically the network behaviour at leading logarithmic accuracy. We also compare our analytic findings to a more realistic neural network trained with Monte Carlo pseudo-data. Fourthly, we compute the unpolarised electron, positron, and photon PDFs at next-to-leading logarithmic accuracy in QED, which are crucial for high-precision predictions needed for future electron-positron colliders. We present both numerical and analytical results. The analytical predictions, defined by means of a specific additive formula, provide a large-z analytical solution that includes all orders in the QED coupling constant alpha, with a small- and intermediate-z solution that includes terms up to alpha cubed.

In questa tesi di dottorato studiamo diversi aspetti delle funzioni di distribuzione partonica (PDF) e di jets per applicazioni alla fisica del Large Hadron Collider (LHC) e dei futuri collisori di particelle. Per prima cosa discutiamo le osservabili di jet misurate a LHC, concentrandoci sulla sezione d’urto di singolo jet inclusiva. Introduciamo possibili definizioni alternative, che pesano i singoli contributi provenienti da ciascun jet in ogni evento e sono quindi unitarie per costruzione. Chiariamo anche l’origine di alcuni aspetti problematici della definizione standard. In secondo luogo, nell’ambito dei fit delle PDF adroniche della collaborazione NNPDF, esamini amo l’inclusione di misure di sezioni d’urto di singolo jet inclusiva e di dijet in un fit di PDF globale, utilizzando le previsioni all’ordine next-to-next-to-leading in QCD per i processi di jet. Questo ci permette di testare sul campo quali osservabili di jet portano a una migliore stabilità perturbativa, a una migliore compatibilità con altri dati sperimentali, a una migliore qualità di fit e a vincoli più rigorosi sulle PDF. In terzo luogo, ci concentriamo su una comprensione analitica delle tecniche di machine learning utilizzate per la discriminazione tra jet originati da quark o gluoni, un tema caldo negli studi sulle sotto-strutture dei jet. Costruiamo una nuova versione della variabile N-subjettiness ampiamente utilizzata, che presenta un comportamento teorico più semplice di quello originale, mantenendo, se non superando, il potere discriminante. Usiamo queste nuove variabili come input della rete neurale più semplice possibile, con un solo neurone, e studiamo analiticamente il comportamento della rete, mantenendo una precisione logaritmica all’ordine leading. In seguito confrontiamo i nostri risultati analitici con una rete neurale più complessa allenata con pseudodati Monte Carlo. In quarto luogo, calcoliamo le PDF di elettrone, positrone e fotone non polarizzati con una precisione logaritmica next-to-leading in QED, ingredienti cruciali per le previsioni ad alta precisione necessarie per i futuri collisori e +e −. Presentiamo risultati sia numerici che analitici. Le previsioni analitiche, definite per mezzo di una specifica formula additiva, forniscono una soluzione analitica a grande-z che include tutti gli ordini nella costante di accoppiamento di QED α, con una soluzione a piccolo e intermedio z, che include termini fino a O(α 3 ).

Full textDescriptive research with qualitative approach, that had as object the strategies of the obstetric nurses' fight to preserve the institutional space of CPDCF as locus in the development of the humanized care. It was selected as objectives: to describe the nurses' professional habitus that act in CPDCF; to analyze the obstetric nurses' position in CPDCF and in the hospital field and to discuss the strategies used by obstetric nurses for us to maintain the humanized model. It was used to support the analysis field concepts, habitus, capital, symbolic violence and to symbolic power under Pierre Bourdieu optics. The research was accomplished with fourteen nurses that work in CPDCF. The data were collected through semi-structured interview and analyzed by the method of contents analysis of Bardin. Two categories were evidenced: 1)The professional habitus of obstetric nurses that act in professional CPDCF whose subcategories expressed the reasons of the insert in nursing and obstetric nursing, the incorporated dispositions for obstetric nurse of CPDCF in your professional formation and the Renewal of habitus; 2) The position and strategies used by obstetric nurses to maintain the model of CPDCF, which subcategories evidenced the position and strategies used by the nurses in CPDCF and the position and strategies used by nurses of CPDC in the referenced hospital. The results evidenced that obstetric nurses of CPDCF use efficient strategies for the maintenance of humanized model at the house and they occupy prestige position because the field favors the development of your abilities in agreement with their desmedicalized habitus.

Full textThis thesis aims to propose extensions of Bayesian quantile regression models, considering proportion data with zero inflation, and also censored data at zero. Initially, it is suggested an analysis of influential observations, based on the location-scale mixture representation of the asymmetric Laplace distribution, where the posterior distribution of the latent variables are compared with the goal of identifying possible outlying observations. Next, a two-part model is proposed to analyze proportion data with zero or one inflation, studying the conditional quantile and the probability of the response variable being equal to zero. Following, Bayesian quantile regression models are proposed for continuous data with a discrete component at zero, where part of these observations are assumed censored. These models may be considered more complete in the analysis of this type of data, as the censoring probability varies with the quantiles of interest. For last, it is considered an application of these models with spacial correlation, in order to study the data about the last presidential election in Brazil in 2014. In this example, the quantile regression models are able to incorporate spatial dependence with the asymmetric Laplace process. For all the proposed models it was developed a R package, which is exemplified in the appendix.

Este es el marco teórico seleccionado para estudiar la mayoría de los problemas. En esta tesis se muestra cómo las propiedades matemáticas de los diseños Pareto óptimos afectan de manera universal a sistemas complejos muy diversos. Las implicaciones en cada fenómeno concreto son discutidas. Se presta especial atención a la optimización de redes complejas, a las características óptimas de posibles códigos de comunicación, y al compromiso que emerge entre estructuras biológicas complejas frente a la eficiencia en la replicación impuesta por la selección Darwiniana.

Full textThis study had the aim to reflect on the by the modern woman after giving birth, particularly the one interpreted by the current biomedical paradigm as postnatal depression . On the contrary of the majority of researches about the issue which associate the phenomenon to physiological alterations related to birth and a supposed emotional fragility characteristic of women we prefer to understand this psychic postnatal suffering as one amongst other possible dimensions of the maternity experience. Our approach is based on the ideas of authors who have studied the social and economical aspects which influenced, during the last three centuries, the construction of the notion of bourgeois family, as well as how the model of the good mother (according to Rousseau) was created in history and then, imposed to the modern woman. To complement this bibliographic survey, we conducted a brief field research with Xavante Indians, in order to get to know how women in this tribe experience maternity, given that their cultural context is completely different from the urban one. The parallel between these two cultures allowed us to elaborate a critical discussion of the modern urban values that guide the experience of the contemporary maternity

Para tanto, investigamos como foi criado o modelo de boa m??e imposto ?? mulher burguesa moderna, a partir de autores que se dedicaram a estudar os aspectos socioculturais e econ??micos que influenciaram, nos ??ltimos tr??s s??culos, a constru????o da fam??lia burguesa. Entramos em contato com a cultura Xavante, na qual as mulheres vivenciam a maternidade em contexto pol??tico, econ??mico, social e cultural bastante distinto daquelas burguesas dos grandes centros urbanos, com a inten????o de relativizar os conceitos da sociedade moderna que tende a universalizar os valores que norteiam a viv??ncia da gesta????o-parto e puerp??rio na sociedade de produ????o. Por fim, propomos que este fen??meno seja compreendido como uma forma da mulher expressar sentimentos banidos pela sociedade simulacral, nos termos que Baudrillard a define, e de resistir ao modelo tradicional de maternidade

Full textIntroduction Fathers and husbands attendance to chilbirth is an increasing trend since 1960s. This phenomenon has marked the history of families and Obstetrics in various contexts. Listening to fathers is an important strategy to improve the mother\'s and babies\' health care, as well as to provide better support to the labour companion. Goals To describe and analyze paternal perspective about the reproductive process, getting to know the elements of childbirth prepare, whether there are implications for the outcome of pregnancy, as well as perceptions about the risks and benefits of obstetric care in different care models. Methods Qualitative research conducted through semi-structured interviews in person, via Skype and e-mail, with a self-selected sample from institutional publicity and social media. Data analyzed from pre-determinates categories, and new themes arising from the data set. Results 23 men were included in the study, all were present at childbirth, attending vaginal birth at hospitals, planned home births, cesarean section intrapartum and scheduled cesarean section. Data show that parents have the desire to attend childbirth as an essential part of their reproductive experience, as well as they enjoy subjective benefits for their fatherhood. During childbirth, fathers qualify their presence with elements of protection and companionship. The expectant management model of care is possible only after negotiation with the birth provider, which also depends on the quality of pacient\'s preparation in terms of information on reproductive rights and best practice recommendations. At the hospital, they also describe the different constraints for the strict compliance of brazilian \'Attendance Childbirth Law\', as well as for the experience of birth as a family event. Conclusions Ensure the unrestricted presence of companion during childbirth brings benefits not only to the health of both mother and baby, but also to the subjective experience of men with the reproductive process and fatherhood. However, fathers involvement is still a challenge posed by many health services being valued only in restricted spaces, more commonly outside hospitals. In large part, the constraints are of the order of control and restriction of personal autonomy in health institutions, contrarying best evidence on effective support and women centered care, which values childbirth as a family experience.

Full textThe asymptotic of the Gerber-Shiu discounted penalty function in Poisson model with Pareto distributed claims is obtained. The asymptotic is obtained as initial surplus x tends to infinity. The main term of discounted penalty function has different expression in case when interest rate equal zero and when doesn't equal zero. The graphs of the Gerber-Shiu discounted penalty function in the case of Pareto claims are examined for various parameter choices.

Full textIn literature, there are numerous papers on the memories of professionals related to childbirth model care; however, maternal memories are scarce. The womens perspective is important because it represents the views and experience of those subjects to childbirth care throughout the history. This study aimed to understand the changes in the childbirth model care from the experience of women who gave birth in the State of Sao Paulo from 1940s to 1980s. A descriptive study was developed with a qualitative approach, using the method of thematic oral history. The colony consisted of 20 women who are mothers, grandmothers and great-grandmother of the first group of graduates of the Midwifery Course - School of Arts, Sciences and Humanities, Universidade de São Paulo. Data were collected through unstructured interviews, based on issues related to the experience of giving birth. A full transcription, textualization and transcriation of oral narratives were made. The final text was submitted to content analysis. The project was approved by the ethics committee and the use of narratives authorized by those interviewed who signed a letter of Oral Testimony Agreement Rights Transfer. The results showed that the women interviewed had a total of 49 births in Sao Paulo, during the period studied. In the decades from 1940 to 1970 (1st generation), there were 22 normal births, one forceps and two cesarean sections, whereas in the 1980s (2nd generation), 16 women had caesarean sections, seven normal births and one forceps. Until the 1960s, home was the predominant place of birth (16 births, out of 25) and the majority was assisted by midwives (20 births). From the next decade on, all births occurred in hospital facilities. Two themes were identified in the thematic analysis: \"The Experience of Childbirth\" (addressing the themes pregnancy and childbirth and the choice of the birth professional) and \"Motherhood and its Context\" (addressing contraception, planning and confirming pregnancy, breastfeeding, caring for the baby and housework). The result indicated a time and generational demarcation in the 1970s. Women\'s experiences of the 1st generation occurred in the context of the transitional childbirth model care while women from the 2nd generation experienced, in the 1980s, the consolidation of a hospital-centered birth model. The 1980s represent a turning point in the elements that compose the childbirth model care, such as the type and place of birth and the professional who assists the mother, with increasing advance in technology and obstetric interventions.

Resumo: Silibinina é um flavonóide quimicamente definido e o principal componente ativo da silimarina, um complexo polifenólico obtido de frutos e sementes de Silybum marianum, que possui propriedades anti-inflamatória, hepatoprotetora e anti-carcinogênica. Objetivo: O objetivo deste trabalho foi avaliar os efeitos da silibinina sobre a performance reprodutiva de ratas prenhes Wistar e as anomalias e/ou malformações de seus fetos. Métodos: Foram utilizadas ratas Wistar prenhes estratificadas em quatro grupos experimentais: controle (n = 6), ratas tratadas com 50mg/kg/dia de silibinina (Grupo I, n = 6), ratas tratadas com 100mg/kg/dia de silibinina (Grupo II, n = 6) e ratas tratadas com 200mg/kg/dia de silibinina (Grupo III, n = 6). Os animais receberam tratamento por via oral (gavage). Durante toda a prenhez, o consumo de ração e a ingestão de água, bem como o ganho de peso corporal foram avaliados. No dia 21 de prenhez as ratas foram anestesiadas A cesárea foi realizada no 21º dia, quando os recém-nascidos foram mortos e processados para análise das variações e/ou malformações. Resultados: os grupos controle e tratados não apresentaram diferenças significativas em relação aos parâmetros fetais, não se observando sinais de toxicidade materna com as diferentes concentrações de silibinina empregadas. Conclusão: O tratamento com silibinina não determinou efeitos deletérios na performance reprodutiva das ratas, mesmo quando utilizada em altas doses (200 mg/Kg/dia).
Abstract: Silibinin is a chemically defined flavonoid and the main active component of silymarin, a polyphenolic complex from fruits and seeds of Silybum marianum, which has anti-inflammatory, hepatoprotective and anticarcinogenic properties. Objective: The aim of the present study was to evaluate the dose-dependent effect of silibinin treatment on maternal reproductive performance and on abnormalities and/or fetal malformations. Methods: Pregnant Wistar rats were distributed in four experimental groups: control, not treated with silibinin (n=6), rats treated with silibinin 50mg/kg/day (Group I, n = 6), rats treated with silibinin 100mg/kg/day (Group II, n = 6) and rats treated with silibinin 200mg/kg/day (Group III, n = 6). Silibinin was administrated by gavage from day 0 to 20 of pregnancy. During the period of pregnancy food and water intake, as well as weight gain were evaluated. On day 21 of pregnancy, the rats were anesthetized and submitted to cesarean section to analyse maternal reproductive performance and fetal malformations. Results: The control and silibinin-treated groups did not show significant differences in relation to the fetal parameters evaluated and no maternal toxicity effects of silibinin were detected in the concentrations employed. Conclusion: Silibinin treatment did not determined deleterious effect on the maternal reproductive performance and fetal outcome even when employed in high dose (200 mg/Kg).
