Influência da doença oncológica na vivência da sexualidade

Enquadramento: A doença oncológica, independentemente da localização ou estadio, assim como os aspectos fisiológicos, psicológicos e sociais a ela associados podem resultar em prejuízo significativo ao nível do funcionamento sexual e relacional do doente. Objetivo: Identificar a influência da doença oncológica na vivência da sexualidade do doente oncológico. Métodos: Estudo de natureza quantitativa, exploratória e descritivo-correlacional, foi realizado com 330 utentes de um Centro Hospitalar na região centro, constituída por 61,5% mulheres e 38,5% homens, com idades compreendidas entre os 25 e os 84 anos (M= 56,05; DP= 12,16). Instrumento de colheita de dados composto por questionário de caracterização sociodemográfica, clínica e a Escala de Apgar Familiar, Smilkstein (1978); Escala de Imagem Corporal (Hopwood, et al 2001); Escala Reduzida de Ajustamento Mental ao Cancro (Watson et al, 1988); Questionário de Satisfação com o Relacionamento Sexual (Cappelleri et al, 2002). Resultados: Da amostra 81,1% é casada ou vive em união de facto, em relação à localização do cancro, 37,9% é localizado na mama e 31,8% digestivo. Relacionamento conjugal antes da doença muito satisfatório (45, 15% ) vs 32,12% nada/pouco satisfatório atualmente. Verificam-se diferenças estatísticamente significativas em algumas variáveis sóciodemográficas (idade, escolaridade), clínicas (localização do tumor, tratamento efetuado), funcionalidade familiar, imagem corporal e ajustamento mental ao cancro, na vivênvia da sexualidade pelo doente oncológico. Conclusão: A assistência aos portadores de doença oncológica deve incluir intervenções dirigidas ao despiste e tratamento da disfunção da sexualidade assim como ao planeamento de ações educativas/formativas dos profissionais de saúde no âmbito da sexualidade do doente oncológico. Palavras-chave: Doença Oncológica; Sexualidade; Imagem corporal; Ajustamento mental.

Bartonella Spp. Bacteremia In Blood Donors From Campinas, Brazil.

Bartonella species are blood-borne, re-emerging organisms, capable of causing prolonged infection with diverse disease manifestations, from asymptomatic bacteremia to chronic debilitating disease and death. This pathogen can survive for over a month in stored blood. However, its prevalence among blood donors is unknown, and screening of blood supplies for this pathogen is not routinely performed. We investigated Bartonella spp. prevalence in 500 blood donors from Campinas, Brazil, based on a cross-sectional design. Blood samples were inoculated into an enrichment liquid growth medium and sub-inoculated onto blood agar. Liquid culture samples and Gram-negative isolates were tested using a genus specific ITS PCR with amplicons sequenced for species identification. Bartonella henselae and Bartonella quintana antibodies were assayed by indirect immunofluorescence. B. henselae was isolated from six donors (1.2%). Sixteen donors (3.2%) were Bartonella-PCR positive after culture in liquid or on solid media, with 15 donors infected with B. henselae and one donor infected with Bartonella clarridgeiae. Antibodies against B. henselae or B. quintana were found in 16% and 32% of 500 blood donors, respectively. Serology was not associated with infection, with only three of 16 Bartonella-infected subjects seropositive for B. henselae or B. quintana. Bartonella DNA was present in the bloodstream of approximately one out of 30 donors from a major blood bank in South America. Negative serology does not rule out Bartonella spp. infection in healthy subjects. Using a combination of liquid and solid cultures, PCR, and DNA sequencing, this study documents for the first time that Bartonella spp. bacteremia occurs in asymptomatic blood donors. Our findings support further evaluation of Bartonella spp. transmission which can occur through blood transfusions.

Experiência e linguagem como estratégias de resistência

Neste artigo visamos apontar, apoiadas em W. Benjamim e G. Agamben, a fragilização do registro da experiência e sua incidência na lógica do poder/violência. Analisamos, pretendendo desmistificar a eficácia dos discursos mortificadores da experiência, a figura do "mulçumano"; - nome que designava os mortos-vivos nos campos de concentração, conforme relato de Primo Levi e outros. Tal figura é emblemática do estado limite a que chegaram algumas pessoas e podem expressar o destino de alguns sujeitos na contemporaneidade. Pudemos identificar nessa posição tanto um movimento na direção da perda do laço identificatório com o semelhante, como uma forma de resistência à violência perpetrada pelo discurso social. Tal resistência consiste em operar uma mimese ao objeto resto, o que permite ao sujeito a manutenção da estrutura fantasmática. Indicamos que, apesar das estratégias do poder, o sujeito reinventa modos de se situar na relação ao Outro, nos quais se fazem importantes a presença e a palavra, incluindo aí a experiência psicanalítica.

Opiniões e atitudes em relação à sexualidade: pesquisa de âmbito nacional, Brasil 2005

OBJETIVO: Descrever opiniões e atitudes sobre sexualidade da população urbana brasileira. MÉTODOS: Inquérito de base populacional realizado em 2005, em amostra representativa de 5.040 entrevistados. Realizou-se análise das atitudes diante da iniciação e educação sexual de adolescentes, considerando sexo, idade, escolaridade, renda, estado civil, religião, cor, região geográfica e opiniões sobre fidelidade, homossexualidade e masturbação. Os resultados foram contrastados com pesquisa similar realizada em 1998, sempre que possível. RESULTADOS: A maioria dos entrevistados escolheu como significado para o sexo a alternativa: "sexo é uma prova de amor". Como em 1998, a maioria manifestou-se pela iniciação sexual dos jovens depois do casamento (63,9% para iniciação feminina vs. 52,4% para a masculina), com diferenças entre praticantes das diversas religiões. A educação escolar de adolescentes sobre o uso do preservativo foi apoiada por 97% dos entrevistados, de todos os grupos sociais. Foi elevada a proporção de brasileiros que concordaram com o acesso ao preservativo nos serviços de saúde (95%) e na escola (83,6%). A fidelidade permaneceu um valor quase unânime e aumentou, em 2005, a proporção dos favoráveis à iniciação sexual depois do casamento, assim como a aceitação da masturbação e da homossexualidade, em relação à pesquisa de 1998. As gerações mais novas tendem a ser mais tolerantes e igualitárias. CONCLUSÕES: Como observado em outros países, confirma-se a dificuldade de estabelecer uma dimensão única que explique a regulação da vida sexual ("liberal" vs "conservador"). Sugere-se que a normatividade relativa à atividade sexual deva ser compreendidas à luz da cultura e organização social da sexualidade ao nível local, auscultadas pelos programas de DST/Aids. A opinião favorável ao acesso livre ao preservativo na escola contrasta com resultados mais lentos no âmbito do combate ao estigma e à discriminação das minorias homossexuais. A formulação de políticas laicas dedicadas à sexualidade permitirá o diálogo entre diferentes perspectivas.

Microbiological and histopathological aspects of canine pyometra

As pyometra is recognized as one of the main causes of disease and death in the bitch the purposes of this study were to evaluate microbiological and histopathological aspects of canine pyometra and to research the virulence factors of the E. coli isolates identifying possible risks to human health. The microbiological isolation from the intrauterine contents of 100 dogs with pyometra was carried out and the virulence factors in the E. coli strains were identified using PCR method. This study also consisted of the counting of microorganisms colonies forming units in samples of intrauterine content, tests of antimicrobial susceptibility of the E. coli isolates and the histological examination of the uterus. E. coli was the most prevalent microorganism isolated (76.6%) and 120 strains (79.5%) were positive for sfa, 86 (56.9%) were positive for cnf, 87 (57.6%) were positive for pap, 52 (34.4%) were positive for hly, 51 (33.8%) were positive for iuc and 5 (3.3%) were positive for afa genes. One observed more sensitivity of E. coli to norfloxacin, polimixin B, sulphazotrin, chloranfenicol and enrofloxacin. In 42% of the samples of uterine walls where microorganisms were isolated, the sizes of the areas of the inflammatory responses corresponded to 39-56%. Virulence factors were identified in 98.0% of the strains evaluated, demonstrating a high frequency of potentially pathogenic E. coli. It must be considered that dogs are animals that are living in close proximity to man for thousands of years and have an important role in the transmission of E. coli to other animals and to man.

The myth of the nation: Historiography of New Zealand architecture since 1907

This paper considers the relationship between the recent historiography (of the last quarter century) of “New Zealand architecture” and the historical notion of “New Zealand-ness” invoked in contemporary architecture. It argues that a more recent programmatic uptake of post-War discussions on national identity and regional specificity has fed the tendencies of practicing architects to defer to history in rhetorical defences of their work: the beach-side mansion as a contemporary expression of the 1950s bach; a formal modernism divorced from the social discourse adherent to the historical moment that it “restates”; and so on. The paper will consider instances in the historiography of New Zealand architecture where historians have compounded, consciously or accidentally, a problem that is systemic to the uses made by architects of historical knowledge (in the most general examples), identifying the difficulties of relying upon the tentative conclusions of an under-studied field in developing principles of contemporary architectural practice under the banners of New Zealand-ness, regionalism, or localism, or with reference to icons of New Zealand architectural history. At the heart of this paper is a reflection on historiographical responsibility in presenting knowledge of a national past to an audience that is eager to transform that knowledge into principles of contemporary production. What, the paper asks, is the historical basis for speaking of a New Zealand architecture? Can we speak of a national history of architecture distinct from a regional history, or from an international history of architecture?

Five-year survival after first-ever stroke and related prognostic factors in the Perth Community Stroke Study

Background and Purpose-Few community-based studies have examined the long-term survival and prognostic factors for death within 5 years after an acute first-ever stroke. This study aimed to determine the absolute and relative survival and the independent baseline prognostic Factors for death over the next 5 years among all individuals and among 30-day survivors after a first-ever stroke in a population of Perth, Western Australia. Methods-Between February 1989 and August 1990, all individuals with a suspected acute stroke or transient ischemic attack of the brain who were resident in a geographically defined region of Perth, Western Australia, with a population of 138 708 people, were registered prospectively and assessed according to standardized diagnostic criteria. Patients were followed up prospectively at 4 months, 12 months, and 5 years after the index event. Results-Three hundred seventy patients with first-ever stroke were registered, and 362 (98%) were followed up at 5 years, by which time 210 (58%) had died. In the first year after stroke the risk of death was 36.5% (95% CI, 31.5% to 41.4%), which was 10-fold (95% CI, 8.3% to 11.7%) higher than that expected among the general population of the same age and sex. The most common cause of death was the index stroke (64%). Between 1 and 5 years after stroke, the annual risk of death was approximately 10% per year, which was approximately 2-fold greater than expected, and the most common cause of death was cardiovascular disease (41%). The independent baseline factors among 30-day survivors that predicted death over 5 years were intermittent clandication (hazard ratio [WR], 1.9; 95% CI, 1.2 to 2.9), urinary incontinence (HR, 2.0; 95% CI, 1.3 to 3.0), previous transient ischemic attack (HR, 2.4; 95% CT, 1.3 to 4.1), and prestroke Barthel Index <20/20 (HR, 2.0, 95% CI, 1.3 to 3.2). Conclusions-One-year survivors of first-ever stroke continue to die over the next 4 years at a rate of approximately 10% per year, which is twice the rate expected among the general population of the same age and sex. The most common cause of death is cardiovascular disease. Long-term survival after stroke may be improved by early, active, and sustained implementation of effective strategies for preventing subsequent cardiovascular events.

The renin-angiotensin system is upregulated in the cortex and hippocampus of patients with temporal lobe epilepsy related to mesial temporal sclerosis

Purpose: As reported by several authors, angiotensin II (AngII) is a proinflammatory molecule that stimulates the release of inflammatory cytokines and activates nuclear factor kappa B (NF kappa B), being also associated with the increase of cellular oxidative stress. Its production depends on the activity of the angiotensin converting enzyme (ACE) that hydrolyzes the inactive precursor angiotensin I (AngI) into AngII. It has been suggested that AngII underlies the physiopathological mechanisms of several brain disorders such as stroke, bipolar disorder, schizophrenia, and disease. The aim of the present work was to localize and quantify AngII AT1 and AT2 receptors in the cortex and hippocampus of patients with temporal lobe epilepsy related to mesial temporal sclerosis (MTS) submitted to corticoamygdalohippocampectomy for seizure control. Method: Immunohistochemistry, Western blot, and real-time PCR techniques were employed to analyze the expression of these receptors. Results: The results showed an upregulation of AngII AT1 receptor as well as its messenger ribonucleic acid (mRNA) expression in the cortex and hippocampus of patients with MTS. In addition, an increased immunoexpression of AngII AT2 receptors was found only in the hippocampus of these patients with no changes in its mRNA levels. Discussion: These data show, for the first time, changes in components of renin-angiotensin system (RAS) that could be implicated in the physiopathology of MTS.

Predictors of Mortality in Patients with Chagas` Cardiomyopathy and Ventricular Tachycardia Not Treated with Implantable Cardioverter-Defibrillators

Methods: We assessed the outcome of 56 patients with Chagas` cardiomyopathy ([31 men]; mean age of 55 years; mean left ventricular ejection fraction [LVEF] 42%) presenting with either sustained ventricular tachycardia (VT) or nonsustained VT (NSVT), before therapy with implantable cardioverter-defibrillator was available at our center. Results: Over a mean follow-up of 38 +/- 16 months (range, 1-61 months), 16 patients (29%) died, 11 due to sudden cardiac death (SCD), and five from progressive heart failure. Survivors and nonsurvivors had comparable baseline characteristics, except for a lower LVEF (46 +/- 7% vs 31 +/- 9%, P < 0.001) and a higher New York Heart Association class (P = 0.003) in those who died during follow-up. Receiver-operator characteristic curve analysis showed that an LVEF cutoff value of 38% had the best accuracy for predicting all-cause mortality and an LVEF cutoff value of 40% had the best accuracy for prediction of SCD. Using the multivariate Cox regression analysis, LVEF < 40% was the only predictor of all-cause mortality (hazard ratio [HR] 12.22, 95% confidence interval [CI] 3.46-43.17, P = 0.0001) and SCD (HR 6.58, 95% CI 1.74-24.88, P = 0.005). Conclusions: Patients with Chagas` cardiomyopathy presenting with either sustained VT or NSVT run a major risk for mortality when had concomitant severe or even moderate LV systolic dysfunction. (PACE 2011; 54-62).

A sexualidade em tempos de internet : representações sociais de estudantes do curso de Enfermagem acerca da sexualidade feminina

O tema Sexualidade abrange diversos aspectos que passam pelas características físicas e pela subjetividade do ser humano, envolvendo percepções e significados. O objetivo deste trabalho é o de analisar as representações de alunas do Curso de Enfermagem acerca da sexualidade feminina, em tempos de internet. Para isso, recorremos à ‘Teoria das Representações Sociais’, por ser um fenômeno sempre ativo dentro da vida social, a partir das contribuições de Moscovici, de Jodelet e de outros. A análise dessas representações, na realidade física e virtual, permite identificar fatores que facilitem ou dificultem a vivência da sexualidade, particularmente, os motivos que levam essas alunas a buscarem relacionamentos virtuais. Optamos pela pesquisa descritiva, com caráter qualitativo, e pela análise de conteúdo para as entrevistas não dirigidas a cinco estudantes da Escola de Enfermagem Materdei em João Pessoa, PB. Buscamos captar, através dos conteúdos de suas falas, gestos, expressões, silêncios e as realidades dos seus discursos, de acordo com Bardin. Constatamos que as alunas do Curso de Enfermagem procuram a Internet para esclarecer dúvidas sobre a sexualidade e, em relação a sexo, consideram importante a privacidade das relações virtuais. Contudo, na relação homem e mulher, contemplam os valores tradicionais de masculinidade e feminilidade.

Occupational exposure to Aflatoxin B1 in Portuguese swine farms

Aflatoxins were first isolated about 40 years ago afier outbreaks of disease and death in turkeys and cancer in rainbow trout fed with rations formulated from peanut and cottonseed meals. These toxins are secondary metabolites produced under certain conditions of temperature, p14 and humidity predominantiy by Aspergilius flavus and Aspergilius parasiticus fungi species. Among 18 different types of aflatoxins identified, major members are aflatoxin B1, B2, G1 and G2. Aflatoxin B1 (AFB1) is normaily predominant in cultures as well as in food products. AFB1 was shown to be genotoxic and a potent hepatocarcinogen. This mycotoxin is metabolized by the mixed function oxidase system to a number of hydroxylated metabolites including the 8,9-epoxide. The latter is considered to be the ultimate carcinogen that reacts with cellular deoxyribonucleic acid (DNA) and proteins to form covalent adducts.

FATAL OUTCOME OF INFECTION BY DENGUE 4 IN A PATIENT WITH THROMBOCYTOPENIC PURPURA AS A COMORBID CONDITION IN BRAZIL

Dengue is currently a major public-health problem. Dengue virus (DENV) is classified into four distinct serotypes, DENV 1-4. After 28 years of absence, DENV-4 was again detected in Brazil in 2010 in Roraima State, and one year later, the virus was identified in the northern Brazilian states of Amazonas and Pará, followed by Rio de Janeiro and São Paulo. In Minas Gerais, the first confirmed case of DENV-4 occurred in the municipality of Frutal in 2011 and has now been isolated from a growing number of patients. Although DENV-2 is associated with the highest risk of severe forms of the disease and death due to the infection, DENV-4 has also been associated with severe forms of the disease and an increasing risk of hemorrhagic manifestations. Herein, the first fatal case of confirmed DENV-4 in Brazil is reported. The patient was an 11-year-old girl from the municipality of Montes Claros in northern Minas Gerais State, Brazil. She had idiopathic thrombocytopenic purpura as a comorbid condition and presented with a fulminant course of infection, leading to death due to hemorrhagic complications. Diagnosis was confirmed by detection of Dengue-specific antibodies using IgM capture enzyme-linked immunosorbent assay and semi-nested RT-PCR. Primary care physicians and other health-care providers should bear in mind that DENV-4 can also result in severe forms of the disease and lead to hemorrhagic complications and death, mainly when dengue infection is associated with coexisting conditions.

Fair procedures. Evidence from games involving lotteries

Procedural fairness plays a prominent role in the social discourse concerning the marketplace in particular, and social institutions in general. Random procedures are a simple case, and they have found application in several important social allocation decisions. We investigate random procedures in the laboratory. We find that an unbiased random procedure is an acceptable substitute for an unbiased allocation: similar patterns of acceptance and rejection result when either is inserted as a feasible proposal in a sequential battle-of-the-sexes. We also find that unbiasedness, known to be a crucial characteristic of allocation fairness, is important to procedural fairness: in the context of a random offer game, a biased outcome is more readily accepted when chosen by an unbiased random draw than by one that is biased. Procedural fairness is conceptually different than allocation fairness or attribution-based behavior, and none of the current models of fairness and reciprocity captures our results. Post hoc extension of one of these models (ERC) suggests that a deeper understanding of procedural fairness requires further investigation of competing fairness norms.
