Valor de la PET en la recurrencia del cáncer de próstata con PSA < 5 ng/ml

We intend to evaluate the usefulness of PET scans in diagnosing recurrent prostate cancer after a curative attempt using radical treatment. MATERIAL AND METHODS: 92 consecutive prostate cancer patients in biochemical progression following radical surgery (63) or radiation treatment (29) were studied with positron emission tomography (PET). In all cases two scans were performed in the same day (11C-choline and 18F-FDG). PET efficacy was evaluated both globally (by employing the results achieved with both 11C-choline and 18F-FDG) and using both radiotracers independently to detect recurrence in patients with biochemical progression. For this purpose, we used comparison of means for k-independent samples, 2 x 2 and 2 x X contingency tables and ROC curves. RESULTS: 1. Global PET: there is evidence of PET alteration regarding the PSA level (P=.003): the clinical stage (P=.01). There are no statistically significant PET alterations regarding the affected biopsy (uni or bilateral), surgical margins, pathological stage and time to progression. ROC curve PET-PSA is statistically significant (P< .0001) permitting calculation of different cut-off points, with a specificity of 91% (highest) for a PSA of 4.3 ng/ml. 2. PET 18FDG: the area under the ROC curve is statistically significant (P< .0001) with a specificity of 91% for a PSA of 6.51 ng/ml. 3. PET 11choline: the area under the ROC curve is statistically significant (P< .0001) with a specificity of 91% for a PSA of 5.15 ng/ml. CONCLUSIONS: PET is a useful tool for diagnosing prostate cancer recurrence after a curative attempt using radical treatment

Impact of renal retransplantation on graft and recipient survival

The aim of this study was to evaluate the influence of retransplantation in graft and recipient survival. METHODS: We carried out a retrospective study in 419 renal transplants and studied the influence of retransplantation in graft and patient survival. A homogeneity study was performed between the two groups with a Student`s T and a chi-square tests. Graft survival analysis was performed with Kaplan-Meyer and log rank tests. RESULTS: Of 419 transplants, 370 (88.3%) were first transplantations, 45 (10.7%) second transplantations and 4(1%) third ones. Mean follow-up of the whole group was 72.5 months (+/-54.1 SD). There were no differences in follow-up between groups (Mean Follow-up 73.1 months +/-54.4 SD in first transplantations vs. 61.6 months +/-51.2 SD in repeat transplantation. p >0.05). The actuarial graft survival showed no differences between patients with first transplantation and those with a repeat one. [3 and 5 year SV of 89% (95% CI: 87-91%) and 84%(95% CI: 82-86%) Vs 88% (95% CI; 83-93%) and 85% (95% CI:i; 80-90%) respectively]. After adjusting for all the heterogeneity variables we still did not find differences on graft survival. The actuarial recipient survival showed no differences between patients with first transplantation and those with a repeat one. [3 and 5 year SV of 98% and 96% Vs.97%]. CONCLUSIONS: There are no differences of graft and recipient survival between patients with a first transplantation and those with a repeat one

Varieties of Non-ordinary Experiences in Brazil—a Critical Review of the Contribution of Studies of ‘Religious Experience’ to the Study of Religion

According to the latest national census, 64.6% of Brazilians identified themselves as Roman Catholic. However, the census has little or nothing to do with actual practice or belief. Professing to be a Christian (within any confessional specification) is still part of being Brazilian. But the self-identification does not take into account that religiosity is expressed in very diverse ways nor does it prevent people from believing and practising one of the many Brazilian traditions though identifying themselves as Christian in the census. This perception represents the framework of the following discussion of non-ordinary experiences in Brazil, whether they are perceived as religious, spiritual or ‘just’ extraordinary. This article presents an overview of studies about non-ordinary experiences in Brazil. The aim is to show the importance of these experiences for the understanding of the religious landscape of Brazil

The pleasure of expense: Mauss and The Gift in contemporary art

Mauss’s The Gift has captured the imagination of generations of artists. As artistic practice shifted from the production of objects to the mediation of situations of social exchange, Mauss’s focus on the ‘pleasure of expense’ has been central, from Bataille and the situationists to relational aesthetics. In most of these cases, Mauss’s arguments were used to question the market economy in ways rather more radical than he himself would have done. However, my objective in this article is not to criticize how Mauss has been misunderstood, but to show how his work has opened a field of new possibilities in art theory and practice

Gender and the Visual Arts

Unlike other forms of material culture, visual art seems always to entail high status. Because of its relationship to high status, unlike other forms of material culture, visual art also always has a relationship with elite markets, high finance, and wealth. Other forms of material culture may be commodities, but visual art is a distinctive class of asset. As a category of material culture, visual art is strongly demarcated against other forms of production and this demarcation is often produced in gendered terms. Whereas men make visual art that can be considered works of great genius, women are more often considered as creating either other forms of material culture or lesser forms of visual art. The demarcations between art and non-art, between the extraordinary and the ordinary, and between male and female work reflect differences in the monetary and social value of the various types of material culture
