A perda gestacional e o processo de luto : quando o início é o fim da vida

O fenómeno da perda gestacional constitui um acontecimento doloroso e terrível para quem o vivencia, gerador de um grande sofrimento, de fortes emoções e de acentuadas dificuldades adaptativas. É na procura da compreensão deste fenómeno que se enquadra a presente investigação, tendo sido definidos como principais objetivos do estudo: compreender o significado atribuído pela mulher à vivência da perda gestacional; compreender as reações da mulher à perda gestacional; identificar as experiências subjetivas da mulher que vivencia uma perda gestacional face aos cuidados de enfermagem; e compreender o significado atribuído pela mulher que vivencia uma perda gestacional ao desempenho dos enfermeiros. Por se tratar de um estudo de natureza qualitativa, de abordagem fenomenológica, assente nos pressupostos de Max Van-Manen, foram consideradas as experiências vividas por 14 mulheres que experienciaram o fenómeno da perda gestacional e o processo de luto há mais de 2 meses. A recolha de dados decorreu entre Agosto de 2011 e Maio de 2012, através da realização de entrevistas semi-estruturadas. Pode-se concluir que, independentemente da idade gestacional aquando da perda, esta é sempre geradora de sentimentos muito dolorosos e penalizadores; que todas as mulheres valorizaram o papel dos enfermeiros, percecionando contudo que as atitudes tomadas por estes nem sempre foram de encontro às suas necessidades; e que este tipo de experiência tem repercussões profundas para a vida da mulher/casal, influenciando até a vivência de gravidezes futuras. Só a compreensão do fenómeno da perda gestacional e do processo de luto assente na perceção e significação atribuída pelas mulheres, dotará os profissionais de saúde e particularmente os enfermeiros de conhecimentos que lhes permitirão adotar atitudes e comportamentos adequados e culturalmente congruentes tendo em conta a especificidade e individualidade de cada mulher/casal/família Palavras-chave: Perda Gestacional, Mulher, Processo de Luto, Cuidados de Enfermagem.ABSTRACT The phenomenon of pregnancy loss is a painful and terrible happening for the person who goes through it. It generates great suffering, strong emotions and very difficult adaptation. The purpose of this investigation is to understand this phenomenon, bearing in mind the following main study goals: to understand the meaning given by the woman to the experience of pregnancy loss; to understand the reactions of a woman who experiences pregnancy loss to the medical care; and to understand the meaning given by the woman who experiences pregnancy loss to the nurse’s care. Since the nature of this study is a qualitative one, of phenomenological approach, based on Max Van-Manen’s conjectures, the experiences of 14 women who experienced the phenomenon of pregnancy loss and the grief process, more than two months ago, were considered. The data collection took place between August 2011 and May 2012 via semistructured interviews. One can conclude that: when the loss of the fetus occurs, no matter the gestational age, it always generates very painful and penalizing feelings; every women appreciated the nurses’ role, observing, however, that the latter’s attitudes not always were directed towards the women’s needs; and that this type of experience has deep impact on the life of the woman/couple, influencing even future pregnancies. Only the comprehension of the phenomenon of pregnancy loss and the grief process, based on the perception and significance given by women, will provide the health professionals, especially nurses, the adequate and culturally congruent behavior and attitude, given the specification and individuality of each woman/couple/family.

Tempo de demora intra-hospitalar das síndromes coronárias agudas

TITULO: Tempo de Demora Intra-hospitalar das Síndromes Coronárias Agudas. ENQUADRAMENTO: A doença coronária, por si só, mantém-se no primeiro lugar das causas de morte na União Europeia. O enfarte agudo do miocárdio (EAM) constitui uma importante causa de morbilidade e mortalidade, sobretudo ao nível dos países industrializados, e resulta, habitualmente, de um processo progressivo de aterosclerose coronária. Todos os anos em Portugal ocorrem cerca de 10.000 EAM. Em doentes com enfarte do miocárdio com supradesnivelamento do segmento ST, a reperfusão precoce é o tratamento de eleição. Manter o menor intervalo de tempo desde o início dos sintomas até à reperfusão é realçado nas guidelines atuais como uma prioridade. OBJECTIVOS: Determinar o tempo de demora intra-hospitalar das Síndromes Coronárias Agudas e analisar a influência de determinadas variáveis no tempo de demora intra-hospitalar, como a idade, o sexo, a forma de admissão (proveniência e tipo de transporte), a prioridade do Sistema de Triagem de Manchester (STM), a dor torácica, o tipo de Síndrome Coronária Aguda (SCA) e a Via Verde Coronária (VVC). MÉTODOS: É um estudo quantitativo e transversal. Amostra constituída por 204 indivíduos com diagnóstico médico de SCA, internados na UCIC do CHTV, EPE, no período compreendido de 1 de Janeiro de 2010 a 30 de Setembro de 2010. A recolha de dados teve por base o registo informático do Sistema ALERT®. RESULTADOS: Os doentes são maioritariamente do sexo masculino (70,1%) com uma média de idades de 69,75 anos (dp=12,74). 63,2% são provenientes do domicílio, 34,8% foram referenciados pelo centro de saúde/SUB. A ambulância sem médico e os meios próprios são o tipo de transporte mais utilizado (44,1% e 42,6% respetivamente). 96,1% dos indivíduos apresentaram dor torácica. 49,0% dos indivíduos foi diagnosticado EAM sem Supra-ST, 32,4% dos indivíduos foi diagnosticado EAM com Supra-ST e 18,6% dos indivíduos foi diagnosticado angina instável. O tempo médio de demora pré-hospitalar (DPH) foi de 1043,11 minutos e o tempo médio entre o início da dor torácica e a admissão no Serviço de Urgência (TDH) foi de 1044,13 minutos; o tempo médio entre a admissão e a realização de triagem (DAT) foi de 8,60 minutos; o tempo médio entre a triagem e a realização do eletrocardiograma (DT-ECG) foi de 34,09 minutos; o tempo médio entre a realização do eletrocardiograma e a primeira observação médica (D-ECGMédico) foi de 20,48 minutos; o tempo médio entre a primeira observação médica e a administração da primeira terapêutica (D-Médico-Terapêutica) foi de 20,25 minutos; o tempo médio entre a admissão e a alta/internamento do doente (DIH-SU) foi de 281,91 minutos, com um tempo mínimo de 6 minutos e máximo de 1500 minutos. 64,7% dos indivíduos fizeram o 1.º ECG no SU num tempo superior a 10 minutos e apenas 35,3% dos indivíduos fizeram o 1.º ECG no SU num tempo 10 minutos. 74,5% dos indivíduos foram triados através do fluxograma Dor Torácica, 70,6% dos indivíduos foram triados com a prioridade laranja e 72,7% dos indivíduos do sexo masculino e 70,5% dos indivíduos do sexo feminino entraram pela VVC. Relativamente ao DIH-SU, o tempo médio foi de 126,71 minutos (dp=141,023) nos indivíduos com EAM com Supra-ST, 340,76 minutos (dp=246,71) nos indivíduos com EAM sem Supra-ST e 396,61 minutos (dp=324,50) nos indivíduos com angina instável. CONCLUSÃO: Os indivíduos do sexo masculino têm um tempo de demora intrahospitalar inferior aos indivíduos do sexo feminino (p> 0,05). Os indivíduos do grupo etário <55 anos apresentam melhores valores médios do tempo entre a admissão e a alta/internamento (p> 0,05). Os indivíduos transferidos do domicílio apresentam melhores valores médios no tempo de demora intra-hospitalar que os indivíduos que são referenciados por outra Instituição de Saúde (p> 0,05).

Qualidade de vida da mulher incontinente urinária

Enquadramento: A incontinência urinária feminina é uma patologia muito frequente, com interferência significativa na qualidade de vida. O tratamento desta patologia é hoje possível na maior parte das doentes. No entanto, o primeiro passo para o sucesso terapêutico é a correcta caracterização do tipo de incontinência, fundamentalmente através do exame clínico (história e exame físico) da doente. Devem ser identificadas as eventuais causas reversíveis ou agravantes e realizar o seu tratamento específico. Objetivos: Este estudo tem como objetivos determinar a qualidade de vida das mulheres com incontinência urinária; analisar a influência dos indicadores pessoais obstétricos, ginecológicos, estilo de vida, e impacto da incontinência na qualidade de vida da mulher com incontinência urinária e determinar a influência da vulnerabilidade ao stresse na qualidade de vida das mulheres com IU. Metodologia: O estudo é exploratório, descritivo e transversal com uma componente correlacional, em 200 mulheres que procuraram o ambulatório de urologia e ginecologia dos hospitais de Viseu, Covilhã e Guarda, no período de março a dezembro de 2012. Como critérios de inclusão temos o facto de as mulheres referirem episódios de perdas urinárias de pelo menos uma vez por semana, nos últimos três meses. Foram excluídas pacientes em período gestacional ou em período de amamentação. Utilizou-se um questionário que permitiu a caracterização socio-demografica, caracterização obstétrica e ginecológica e estilos de vida e as escalas: Impacto da IU (ICIQ-SF), Valorização da IU; Qualidade de Vida em Mulheres com IU (KHQ) e Vulnerabilidade ao Stresse (23 QVS). Resultados: Há uma percentagem significativa de mulheres acima dos 58 anos com IU moderada. As mulheres abaixo dos 57 anos tendem a apresentar valores mais elevados de IU de urgência. As mulheres com profissões intelectuais e técnicas apresentam IU de esforço. As mulheres com IU de urgência tiveram parto normal. As mulheres com IU grave têm IU de esforço e IU de urgência. Não foi encontrada associação entre a IU de esforço e a IU de urgência quanto ao estado civil, área de residência, IMC, nº de gravidezes e nº de filhos. Relativamente à vulnerabilidade ao stresse, as mulheres com IU não são vulneráveis contudo, as entrevistadas referiram a existência de stresse no trabalho e nos afetos. As participantes com menos de 57 anos apresentam maior vulnerabilidade ao stresse face ao perfecionismo, inibição, condição de vida e subjugação. As que residem em zona urbana com profissões intelectuais tendem a ser mais vulneráveis ao stresse. As mulheres com IU acima dos 58 anos têm melhor QDV face à sua limitação física e às suas medidas de gravidade. As mulheres com QDV moderada têm profissões técnicas, têm 1 filho e têm um impacto de IU muito grave. As mulheres com QDV fraca fizeram cesariana. As mulheres com QDV elevada têm um impacto da IU moderada. São fatores preditores das dimensões da QDV: (1) perceção da saúde - nível do IMC, perfecionismo e impacto da IU de esforço; (2) impacto da IU - vulnerabilidade ao stresse, IU de urgência e dramatização; (3) limitação no desempenho das tarefas - IU de urgência, vulnerabilidade ao stresse, dramatização e perfecionismo; (4) limitação física - vulnerabilidade ao stresse e IU de urgência; (5) limitação social - impacto da IU de urgência, à deprivação, à dramatização e ao perfecionismo; (6) relações pessoais - inibição, idade e IU de urgência; (7) emoções - inibição, IU de urgência, deprivação, dramatização e carência; (8) sono e energia - idade, carência e deprivação; (9) medidas de gravidade - dramatização, carência, perfecionismo e vulnerabilidade ao stresse. Conclusão: A qualidade de vida das mulheres com IU é influenciada pela idade, profissão, nº de filhos, tipo de parto, impacto da IU, pela deprivação e dramatização associada ao stresse e, ainda, pelo impacto da IU de urgência.

The treatment of this pathology is today possible in most of the patients. However, the first step for the therapeutic success is the certain characterization of the incontinence type, fundamentally through the clinical exam (history and physical exam) of the patient. They should be identified the eventual reversible causes or added difficulties and to accomplish his specific treatment. Objective:This study has as objectives to determine the women's quality of life with urinary incontinence; to analyze the influence of the obstetric, gynecological personal indicators, lifestyle, and impact of the incontinence in the woman's quality of life with urinary incontinence and to determine the influence of the vulnerability to the stresse in the women's quality of life with IU. Methods: The study is exploratory, descriptive and traverses with a correlation, in 200 women that sought the urology clinic and gynecology of the hospitals of Viseu, Covilhã and Guard, in the period of March to December of 2012. The patients included in the study were considered incontinent to declare episodes of urinary losses of at least once a week, in the last three months. They were excluded patient in gestation period or in breast-feeding period. We used a questionnaire that allowed the characterization socio-demographic, obstetric and gynecological characteristics and lifestyles and scales: Impact of UI (ICIQ-SF), Valuing UI, Quality of Life in Women with UI (KHQ) and Vulnerability to Stress (23 QVS). Results of the impact of IU: There is a significant percentage of women above the 58 years with moderate IU. The women below the 57 years tend to present higher values of urgency IU. The intellectual and technical professions present IU of effort. The women with urgency IU had normal childbirth. The women with serious IU have IU of effort and urgency IU. It was not found association between IU of effort and urgency IU as for the marital status, residence area, IMC, pregnancies number and children's number. Results of the stress vulnerability: The women with IU are no vulnerable however; the women interviewees referred the stress existence in the work and in the affections. The women below the 57 years present larger to the stress vulnerability face to the perfectionism, inhibition, life condition and subjugation. The women that live in urban area with intellectual professions tend to be more to the stress vulnerable. Results of the quality life: The women with IU above the 58 years have better QDV to his physical limitation and their gravity measures. The women with moderate QDV have technical professions, they have 1 son and they have an impact of very serious IU. The women with weak QDV made Cesarean. The women with high QDV have an impact of moderate IU. Factors that predict QDV: (1) perception of the health - level of IMC, perfectionism and impact of IU of effort; (2) impact of IU - stress vulnerability, urgency IU and dramatization; (3) limitation in the acting of the tasks - urgency IU, stress vulnerability, dramatization and perfectionism; (4) physical limitation - stress vulnerability and urgency IU; (5) social limitation - impact of urgency IU, to the affections privation, to the dramatization and the perfectionism; (6) relationships - inhibition, age and urgency IU; (7) emotions - inhibition, urgency IU, affections privation, dramatization and lack; (8) sleep and energy - age, lack and affections privation; (9) gravity measures - dramatization, lack, perfectionism and stress vulnerability. Conclusion: The quality of the women's life with IU is influenced by the age, profession, number of children, childbirth type, impact of IU, for the affections privation and dramatization associated to the stress and, still, for the impact of urgency IU.

Higgs boson production in photon-photon collision at ILC: a comparative study in different little Higgs models

We study the process \gamma\gamma->h->bb_bar at ILC as a probe of different little Higgs models, including the simplest little Higgs model (SLH), the littlest Higgs model (LH), and two types of littlest Higgs models with T-parity (LHT-I, LHT-II). Compared with the Standard Model (SM) prediction, the production rate is found to be sizably altered in these little Higgs models and, more interestingly, different models give different predictions. We find that the production rate can be possibly enhanced only in the LHT-II for some part of the parameter space, while in all other cases the rate is suppressed. The suppression can be 10% in the LH and as much as 60% in both the SLH and the LHT-I/LHT-II. The severe suppression in the SLH happens for a large \tan\beta and a small m_h, in which the new decay mode h->\eta\eta (\eta is a light pseudo-scalar) is dominant; while for the LHT-I/LHT-II the large suppression occurs when f and m_h are both small so that the new decay mode h->A_H A_H is dominant. Therefore, the precision measurement of such a production process at the ILC will allow for a test of these models and even distinguish between different scenarios.Comment: Version in JHEP (h-g-g & h-gamma-gamma expressions added

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb^-1. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final version published in European Physical Journal

Search for direct pair production of the top squark in all-hadronic final states in proton-proton collisions at s√=8 TeV with the ATLAS detector

The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1fb−1 of proton–proton collision data at √s = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is assumed to decay via t˜→tχ˜01 or t˜→ bχ˜±1 →bW(∗)χ˜01 , where χ˜01 (χ˜±1 ) denotes the lightest neutralino (chargino) in supersymmetric models. The search targets a fully-hadronic final state in events with four or more jets and large missing transverse momentum. No significant excess over the Standard Model background prediction is observed, and exclusion limits are reported in terms of the top squark and neutralino masses and as a function of the branching fraction of t˜ → tχ˜01 . For a branching fraction of 100%, top squark masses in the range 270–645 GeV are excluded for χ˜01 masses below 30 GeV. For a branching fraction of 50% to either t˜ → tχ˜01 or t˜ → bχ˜±1 , and assuming the χ˜±1 mass to be twice the χ˜01 mass, top squark masses in the range 250–550 GeV are excluded for χ˜01 masses below 60 GeV

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Search for R-parity-violating supersymmetry in events with four or more leptons in sqrt(s) =7 TeV pp collisions with the ATLAS detector

A search for new phenomena in final states with four or more leptons (electrons or muons) is presented. The analysis is based on 4.7 fb−1 of $\sqrt{s}=7\;\mathrm{TeV}$ proton-proton collisions delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in two signal regions: one that requires moderate values of missing transverse momentum and another that requires large effective mass. The results are interpreted in a simplified model of R-parity-violating supersymmetry in which a 95% CL exclusion region is set for charged wino masses up to 540 GeV. In an R-parity-violating MSUGRA/CMSSM model, values of m 1/2 up to 820 GeV are excluded for 10 < tan β < 40

Measurement of the cross-section of high transverse momentum vector bosons reconstructed as single jets and studies of jet substructure in pp collisions at √s = 7 TeV with the ATLAS detector

This paper presents a measurement of the cross-section for high transverse momentum W and Z bosons produced in pp collisions and decaying to all-hadronic final states. The data used in the analysis were recorded by the ATLAS detector at the CERN Large Hadron Collider at a centre-of-mass energy of √s = 7 TeV;{\rm Te}{\rm V}$and correspond to an integrated luminosity of$4.6\;{\rm f}{{{\rm b}}^{-1}}$. The measurement is performed by reconstructing the boosted W or Z bosons in single jets. The reconstructed jet mass is used to identify the W and Z bosons, and a jet substructure method based on energy cluster information in the jet centre-of-mass frame is used to suppress the large multi-jet background. The cross-section for events with a hadronically decaying W or Z boson, with transverse momentum${{p}_{{\rm T}}}\gt 320\;{\rm Ge}{\rm V}$and pseudorapidity$|\eta |\lt 1.9$, is measured to be${{\sigma }_{W+Z}}=8.5\pm 1.7$ pb and is compared to next-to-leading-order calculations. The selected events are further used to study jet grooming techniques
