Isokinetic assessment of knee flexor/extensor muscular strength in elderly women

OBJECTIVE: To assess knee flexor-extensor muscular strength in elderly women with no previous history of musculoskeletal disorders on the lower limbs using an isokinetic dynamometer, in order to obtain data that could be used as a comparative parameter in the evaluation of elderly women with knee disorders, thus facilitating a better rehabilitation of these patients. METHODS: Twenty-six volunteers aged 75 to 83 years were studied using a Cybex® 6000 isokinetic dynamometer. The chosen angular velocity was 60 º/s, and concentric exercise was used for either flexion or extension. The studied parameters were: peak torque, angle of peak torque, and flexor-extensor torque rate. RESULTS: There were no differences between dominant (D) and nondominant (ND) knee peak torque values. This was true for both flexor (D = 42.46 ± 9.09 Nm / ND = 40.65 ± 9.38 Nm) and extensor (D = 76.92 ± 13.97 Nm / ND = 77.65 ± 15.21 Nm) movements. The descriptive statistical analysis of the values obtained for the flexor-extensor peak torque rate and for the angle of occurrence of peak torque was the same for the dominant and nondominant sides. CONCLUSIONS: The values of peak torque for the contralateral side can be used as a reference during rehabilitation of elderly women with acute disease of the knee, and the angular velocity of 60 º/s is proper and safe for isokinetic assessment of elderly people.

Pathological gambling in women: a review

Pathological gambling was only recently recognized as a psychiatric disorder (DSM-III, APA, 1980). Most studies of pathological gambling include only male subjects. Despite the paucity of information, it is likely that at least one-third of pathological gamblers are women. The objective of this article is to review clinical and epidemiological characteristics of female gamblers as compared to their male counterparts. MEDLINE and PsycINFO were searched for investigational studies and reviews of the past 10 years on clinical (sociodemographic, course and progression, psychiatric comorbidities, genetics, and personality) and epidemiological aspects of female gamblers. Other relevant articles were also selected from reference lists. It is concluded that the current literature indicates some common characteristics in female and male gamblers, but it also indicates the possibility that each gender may carry etiopathogenic differences that when better understood should lead to improved treatment and prevention strategies.

Breaking the Pattern and Creating New Paths – Feminist Mizrahi Women Artists in Israel

This article addresses the work of Mizrahi women artists, i.e., Israeli-Jewish women of Asian or African ethnic origin, using the artist Vered Nissim as a case study. Nissim seeks to affirm the politics of identity and recognition, as well as feminism in order to create a paradigm shift with regards to the local regime of cultural representations in the Israeli art scene. Endeavouring to find ways of undermining the rigid imbalances between different social groups, she calls for a comprehensive reform of the status quo through artistic activism. Nissim employs a style, content, and medium that disrupts the accepted social order, using humour and irony as unique weapons with which she takes liberties with conventional moral, social, and economic values. Placing issues of race, class and gender at the centre of her work, she seeks to undermine and problematize essentialist attitudes, highlighting the political intersections of different identity categories as the critical analysis of intersectionality unfolds.

Dispondo de si : autonomia, género e envelhecimento nos quotidianos de saúde

Esta tese de doutoramento tem como objectivo geral compreender as experiências de autonomia individual na actual geração de adultos mais velhos, enquadrados pelas construções identitárias de género e assumindo como plataforma de observação as vivências quotidianas de saúde. Para tanto, justifica-se a centralidade do valor da autonomia individual na contemporaneidade, para depois se problematizar o conceito a partir de uma perspectiva feminista, com base na conceptualização proposta por este corpo teórico. O feminismo propõe a adopção do conceito de autonomia relacional, que ao reconhecer a natureza social do self e das identidades, é capaz de proporcionar uma leitura crítica e contextualizada da autonomia de cada sujeito, por integrar não só as especificidades, estímulos, oportunidades e contingências de um tempo e de um espaço social, como também o poder resolutivo, transformador e de resistência da agência individual. A vivência da velhice constitui, cada vez mais, um exercício de individualidade. No envelhecer, a vivência da saúde ganha especiais contornos. Não só porque o cuidar de si se tornou um aspecto biográfico de progressiva acentuação, como também por ser este um tempo da vida em que os dilemas, inquietações e exigências com o corpo se acentuam. A individualização dos trajectos biográficos que nas sociedades contemporâneas surge com cada vez maior expressão sugere a importância do estudo das diferentes ecologias sociais, com base na precisão e no detalhe. A tese adoptou uma estratégia metodológica de estudos de casos, concretizada num estudo de caso múltiplo, de tipo qualitativo. Os sentidos conferidos às experiências da autonomia individual pela actual geração de adultos mais velhos, nos seus quotidianos de saúde, mobilizam e matizam diferentes modelos culturais, iluminando a ideia de uma transição sociocultural que abandona parcialmente certos aspectos, mas que mantém tantos outros. No envelhecer, a vivência da autonomia individual é mediatizada por diferentes performatividades femininas e masculinas, tendo sido três os espaços principais de expressão social da autonomia, resultantes do seu cruzamento com o género, enquanto dimensão de análise principal. Tem-se que estas diferenças entre espaços factoriais vêm demonstrar o hibridismo dos posicionamentos resultante da crescente individualidade das trajectórias de vida. Face à saúde, a capacidade de adaptação e de auto-gestão mais positivos relacionam-se, face às mulheres, com a expressão singular de uma maior individualidade e, face aos homens, com o valor social conferido a diferentes masculinidades.

Gestão de museus : o caso do Museu Nacional de Arqueologia

O presente trabalho pretende caraterizar o regime atual de governação do MNA descrevendo-o do ponto de vista dos recursos financeiros, recursos humanos, marketing e planeamento, tendo em conta a sua dependência da Direção Geral de Património Cultural, complementarmente pretende apresentar algumas propostas de melhoria. Desde a sua criação o Museu Nacional de Arqueologia, tem por objetivo representar a parte material da vida do homem português desde a pré-história. Hoje, constitui a instituição de referência da Arqueologia Portuguesa, ligado a outros museus, universidades e centros de investigação por todo o mundo. Num momento em que num número crescente de países, os museus e instituições culturais têm de procurar fontes alternativas de financiamento, por força do desinvestimento por parte dos Estados, e a reduzir os gastos, incluindo restrições às contratações de recursos humanos, coloca-se um grande desafio àqueles que gerem estas instituições. Por um lado, valências como lojas com artigos ligados ao museu e a concessão de espaços de restauração nas suas instalações, a organização de eventos temáticos lúdico-pedagógicos, acompanhados de uma estratégia de comunicação segmentada, contribuem para a diversificação e o aumento de públicos. Por outro lado, atividades de fundraising devem passar a ser uma prática comum nestas entidades. Tudo isto, tendo sempre presente que se trata de uma entidade cultural com uma função de produção de conhecimento e cultura, não devendo o Estado alhear-se desta função. O Museu Nacional de Arqueologia, é tutelado pela Direção Geral do Património Cultural o que impõe constrangimentos ao nível da gestão. Embora seja possível, pela direção do MNA, tomar decisões relativas à área financeira, a perceção do seu impacto não é imediata. No que respeita aos recursos humanos, estamos perante um quadro qualificado, capaz de dar resposta às exigências do funcionamento do museu, mas que pela média etária e pelas dificuldades de contratação, coloca em risco o futuro. O marketing e o planeamento são as áreas em análise que apresentam menos constrangimentos, pela dependência da tutela. Os processos de marketing são concretizados pelos diferentes departamentos, com uma abordagem tradicional, ou seja unilateral, verificando-se pouca interação com os seus públicos. O plano de atividades é bastante completo e é uma boa ferramenta de gestão no que respeita ao planeamento, assim como o planeamento de carácter estratégico permite ao museu seguir uma linha de continuidade.

Gender norms in Portuguese college sudents' judgments in familial homicides: bad men and mad women

The gender of the offender has been proved to be an important factor in judicial sentencing. In this study, we analyze the judgments of College students regarding perpetrators of familial homicides to evaluate the presence of these gender norms and biases in the larger society. The sample included 303 college students (54.8% female) enrolled in several social sciences and engineering courses. Participants were asked to read 12 vignettes based on real crimes taken from Portuguese newspapers. Half were related to infanticide, and half were related to intimate partner homicide. The sex of the offender was orthogonally manipulated to the type of crime. The results show that gender had an important impact on sentences, with males being more harshly penalized by reasons of perversity and women less penalized by reason of mental disorders. In addition, filicide was more heavily penalized than was intimate partner homicide. The results also revealed a tendency toward a retributive conception of punishment. We discuss how gender norms in justice seem to be embedded in society as well as the need for intervention against the punitive tendency of this population.

Clustering-based approach for categorizing pregnant women in obstetrics and maternity care

When a pregnant woman is guided to a hospital for obstetrics purposes, many outcomes are possible, depending on her current conditions. An improved understanding of these conditions could provide a more direct medical approach by categorizing the different types of patients, enabling a faster response to risk situations, and therefore increasing the quality of services. In this case study, the characteristics of the patients admitted in the maternity care unit of Centro Hospitalar of Porto are acknowledged, allowing categorizing the patient women through clustering techniques. The main goal is to predict the patients’ route through the maternity care, adapting the services according to their conditions, providing the best clinical decisions and a cost-effective treatment to patients. The models developed presented very interesting results, being the best clustering evaluation index: 0.65. The evaluation of the clustering algorithms proved the viability of using clustering based data mining models to characterize pregnant patients, identifying which conditions can be used as an alert to prevent the occurrence of medical complications.

Studying conformally flat spacetimes with an elastic stress energy tensor using 1+3 formalism

Conformally flat spacetimes with an elastic stress energy tensor having diagonal trace-free anisotropic pressure are investigated using 1+3 formalism. The 1+3 Bianchi and Jacobi identities and Einstein field equations are written for a particular case with a conformal factor dependent on only one spatial coordinate. Solutions with non null anisotropic pressure are obtained.

Narrative innovations predict symptom improvement: Studying innovative moments in narrative therapy of depression

Objective:Innovative moments (IMs) are moments in the therapeutic dialog that constitute exceptions toward the client's problems. These narrative markers of meaning transformation are associated with change in different models of therapy and diverse diagnoses. Our goal is to test if IMs precede symptoms change, or, on the contrary, are a mere consequence of symptomatic 15 change. Method: For this purpose, IMs and symptomatology (Outcome Questionnaire-10.2) were assessed at every session in a sample of 10 cases of narrative therapy for depression. Hierarchical linear modeling was conducted to explore whether (i) IMs in a given session predict patients' symptoms in the following session and/or (ii) symptoms in a given session predict IMs in the next session. Results: Results suggested that IMs are better predictors of symptoms than the reverse. Conclusions: These results are discussed considering the contribution of meanings and narrative processes' changes to symptomatic improvement.

Quality of life in women with urinary incontinence

The aim of this study is to examine the relationship among psychological, clinical and sociodemographic variables, and quality of life in women with urinary incontinence. The sample consisted of 80 women diagnosed with urinary incontinence (UI) followed in a Northern Central Hospital in Portugal. Participants answered the Incontinence Quality of Life (I-QOL); Satisfaction with Sexual Relationship Questionnaire (SSRQ); Hospital Anxiety and Depression Scales (HADS) and the Brief Cope. The results revealed that women with higher quality of life considered their symptoms of urine loss as mild or moderated compared to those with severe urine loss. The less severe urine loss was associated with greater sexual satisfaction and less use of religion and self-blame as coping strategies. In terms of coping, women who considered the loss of urine as severe expressed more feelings regarding UI. Stress urinary incontinence, high sexual satisfaction, and less use of denial, distraction, and religion as coping strategies, predicted higher quality of life. According to the results, UI has an impact on women’s sexual satisfaction and quality of life. Therefore, intervention programs should target these women, including their partners, helping them to adjust to their condition and teaching effective coping strategies in order to improve their sexual satisfaction and quality of life.

Clinical characteristics of women diagnosed with carcinoma who tested positive for cervical and anal high-risk human papillomavirus DNA and E6 RNA

High-risk human papillomavirus (hrHPV) is an essential cause of cervical carcinoma and is also strongly related to anal cancer development. The hrHPV E6 oncoprotein plays a major role in carcinogenesis. We aimed to evaluate the frequency of hrHPV DNA and E6 oncoprotein in the anuses of women with cervical carcinoma. We analyzed 117 women with cervical cancer and 103 controls for hrHPV and the E6 oncogene. Positive test results for a cervical carcinoma included 66.7 % with hrHPV-16 and 7.7 % with hrHPV-18. One case tested positive for both HPV variants (0.9 %). The samples from the anal canal were positive for HPV-16 in 59.8 % of the cases. Simultaneous presence of HPV in the cervix and anal canal was found in 53.8 % of the cases. Regarding expression of E6 RNA, positivity for HPV-16 in the anal canal was found in 21.2 % of the cases, positivity for HPV-16 in the cervix was found in 75.0 %, and positivity for HPV-18 in the cervix was found in 1.9 %. E6 expression in both the cervix and anal canal was found in 19.2 % of the cases. In the controls, 1 % tested positive for HPV-16 and 0 % for HPV-18. Anal samples from the controls showed a hrHPV frequency of 4.9 % (only HPV16). The presence of hrHPV in the anal canal of women with cervical cancer was detected at a high frequency. We also detected E6 RNA expression in the anal canal of women with cervical cancer, suggesting that these women are at risk for anal hrHPV infection.

Current and previous eating practices among women recovered from anorexia nervosa: a qualitative approach

OBJECTIVE: The aim of this study was to analyze qualitatively how women, who have recovered from anorexia nervosa, perceive and describe their current eating practices, as well as the ones developed during the eating disorder period. METHODS: Seven women were interviewed individually with the objective of investigating their eating practices, transition phases and all relevant aspects that somewhat contributed to the habit-forming; experiences, feelings and perceptions related to mealtime and the influence that food has had over the present subjects' life. The interviews were analyzed by the discourse of the collective subject method. RESULTS: The results brought up the following topics: a) control; b) concerns and feelings; c) deprivation d) beauty dictatorship; e) eating competence; f) importance of food; g) food cacophony. CONCLUSIONS: What stands out is a multiplicity of eating practices, which during the eating disorder were similar to and characterized by restriction; however, after recovery, part of the subjects seem to have developed a higher eating competence, whereas others show a practice similar to the one acquired during the anorexia nervosa, such as the difficulty in realizing when they are satisfied and a feeling of discomfort when facing social interactions.

Binge eating prevalence according to obesity degrees and associated factors in women

Objective Investigate binge eating (BE) prevalence in women according to the obesity degree and assess the associated factors. Methods Cross-sectional study with female adults presenting body mass index (BMI) ≥ 35 kg/m2. The analyzed variables were: sociodemographics, health status, obesity history, lifestyle, eating behavior and obesity degree. In order to analyse BE it was used the Binge Eating Scale (BES), which is considered positive when BES ≥ 18 points. Prevalence and prevalence ratios (PR) were calculated with confidence intervals (CI) of 95%. Multivariate analysis was carried out using Poisson regression. Results BE prevalence was 53.2%, and the prevalence in super superobese women (BMI ≥ 60 kg/m2) was 75%. After multivariate analysis, associations were observed between the age group 40-49 years old (PR = 2.0; 95% CI = 1.2-3.4) and the “snacking habit” (PR = 1.9; 95% CI = 1.2-2.9). Conclusion The prevalence of BE in severe obese women was high. Association with the “snacking habit” can be a BE marker that should be monitored in the severely obese individuals that fit this profile.
