Predictors of consistent condom use among Portuguese women attending family planning clinics

Women account for 30% of all AIDS cases reported to the Health Ministry in Portugal and most infections are acquired through unprotected heterosexual sex with infected partners. This study analyzed socio-demographic and psychosocial predictors of consistent condom use and the role of education as a moderator variable among Portuguese women attending family planning clinics. A cross-sectional study using interviewer-administered fully structured questionnaires was conducted among 767 sexually active women (ages 18–65). Logistic regression analyses were used to explore the association between consistent condom use and the predictor variables. Overall, 78.7% of the women were inconsistent condom users. The results showed that consistent condom use was predicted by marital status (being not married), having greater perceptions of condom negotiation self-efficacy, having preparatory safer sexual behaviors, and not using condoms only when practicing abstinence. Living with a partner and having lack of risk perception significantly predicted inconsistent condom use. Less educated women were less likely to use condoms even when they perceive being at risk. The full model explained 53% of the variance in consistent condom use. This study emphasizes the need for implementing effective prevention interventions in this population showing the importance of taking education into consideration.

Gastric adenocarcinoma: contribute of computed tomography in preoperative T nad N staging

RESUMO:Os recentes progressos na imagiologia médica possibilitaram um papel de destaque para a Tomografia Axial Computorizada Multicorte no estadiamento do carcinoma do estômago (GA). Foi objetivo deste estudo avaliar a acuidade desta técnica no estadiamento T (invasão mural) e N (ganglionar) e avaliar fatores de prognóstico como fatores de representação/substituição para melhorar a referida acuidade. Sessenta e nove pacientes operados a carcinoma gástrico (GA) entre Janeiro de 2010 e Julho de 2012 e avaliados por Tomografia Computorizada, a maioria recorrendo a técnica de multicorte com distensão gástrica, foram estadiados retrospetivamente por três imagiologistas. Utilizaram-se critérios de avaliação referidos na literatura especializada e fatores de substituição/representação nos estadios menos eficazes. O estadiamento T revelou acuidade de 66,7% e sensibilidade de 92% e a acuidade, sensibilidade e especificidade obtidas para o estadiamento N foram respetivamente 49%, 40,9% e 64%. Usando um fator de substituição de estadiamento diagnóstico T4/N2 para mudar o estadiamento N2 obtido por MDCT para estadiamento N3A aumentaria a acuidade do estadiamento N para 59% e a sensibilidade para 58,1% e baixaria a especificidade para 61,5%, embora essa mudança não fosse estatisticamente significativa (Teste exato de Fisher 0,159). Em conclusão a acuidade de uma técnica simples de MDCT com distensão gástrica no estadiamento T e N do GA está dentro dos valores citados na literatura e fatores de substituição/representação como o estadiamento T4 e o tipo Difuso da classificação de Lauren podem melhorar a acuidade do estadiamento N.-------------- ABSTRACT: Recent innovations in medical sectional imaging have allowed a major role of multi-detector computed tomography (MDCT) in staging of gastric adenocarcinoma (GA). The purpose of this study was to evaluate the accuracy of this technique in depth of mural invasion (T) and nodal (N) staging of GA and to evaluate prognostic factors as surrogate factors to improve such accuracy. Sixty nine patients operated to GA between January 2010 and July 2012 that underwent Computed Tomography, the majority through Multidetector Computed Tomography (MDCT) with gastric distention, were staged retrospectively by three imagiologists with state-of-the-art criteria and surrogate prognostic factors were analyzed for less accurate stages. MDCT T-staging was 66,7 % accurate with a sensibility of 92 % and there was a 49 % accuracy, 40,9 % sensibility and 64 % specificity for N Staging. Using a surrogate factor of T4/N2 diagnostic staging to change diagnostic MDCT N2 disease to N3A disease would increase accuracy of N staging to 59% and sensibility to 58,1% and would decrease specificity to 61,5 %, although that change was not statistically significant (Fisher´s Exact Test 0,159)In conclusion the accuracy of a simple hydro-MDCT technique in T and N staging of GA is in the range of values cited in the literature and surrogate factors as diagnostic T4 disease and diffuse type of Lauren´s Classification may improve the accuracy of N staging.

Planning and verification of multipath routing protocols

Conventionally the problem of the best path in a network refers to the shortest path problem. However, for the vast majority of networks present nowadays this solution has some limitations which directly affect their proper functioning, as well as an inefficient use of their potentialities. Problems at the level of large networks where graphs of high complexity are commonly present as well as the appearing of new services and their respective requirements, are intrinsically related to the inability of this solution. In order to overcome the needs present in these networks, a new approach to the problem of the best path must be explored. One solution that has aroused more interest in the scientific community considers the use of multiple paths between two network nodes, where they can all now be considered as the best path between those nodes. Therefore, the routing will be discontinued only by minimizing one metric, where only one path between nodes is chosen, and shall be made by the selection of one of many paths, thereby allowing the use of a greater diversity of the present paths (obviously, if the network consents). The establishment of multi-path routing in a given network has several advantages for its operation. Its use may well improve the distribution of network traffic, improve recovery time to failure, or it can still offer a greater control of the network by its administrator. These factors still have greater relevance when networks have large dimensions, as well as when their constitution is of high complexity, such as the Internet, where multiple networks managed by different entities are interconnected. A large part of the growing need to use multipath protocols is associated to the routing made based on policies. Therefore, paths with different characteristics can be considered with equal level of preference, and thus be part of the solution for the best way problem. To perform multi-path routing using protocols based only on the destination address has some limitations but it is possible. Concepts of graph theory of algebraic structures can be used to describe how the routes are calculated and classified, enabling to model the routing problem. This thesis studies and analyzes multi-path routing protocols from the known literature and derives a new algebraic condition which allows the correct operation of these protocols without any network restriction. It also develops a range of software tools that allows the planning and the respective verification/validation of new protocols models according to the study made.
