Functional MRI evaluation of liver tumour response after radiofrequency: short- and mid-term evolution of diffusion parameters

Purpose: To evaluate the short- and mid-term evolutions of the apparent diffusion coefficient of lesions treated with RF, in order to determine if the ADC can be used as a marker of tumour response. Methods and Materials: Twenty patients were treated for a liver malignancy with RF and were examined on a 1.5 T/3.0 T machine with T2, gadolinium-enhanced T1 and diffusion sequences: before treatment (< 1 month), just after treatment (< 1 month) and midterm (3-6 months). The ADC was measured in the whole lesion and in the area with the most restricted diffusion (MRDA). The ROI size was also measured on the diffusion map. The Pearson/ANOVA tests were used. Results: All patients were successfully treated with complete disappearance of CE. The lesional size on T2 showed a negative evolution in time (p < 0.002). The ADC in the whole lesion showed a bell-shaped evolution (increasing just after RF, then decreasing, p = 0.02). The ROI size on the diffusion map followed a similar course (p = 0.01). For the MRDA, such evolutions were also found, but they were not significant. There was a negative correlation between CE and the ADC (p < 0.02) and between the lesional size on T2 and ADC (p = 0.03) in the whole lesion. There were also positive correlations between the ROI size and ADC (p = 0.0008) and between CE and the size on T2 (p = 0.0002). The ADC in MRDA showed some non-significant correlations with other variables. Conclusion: The lesions successfully treated with RF have a clear and predictable evolution in terms of T2 size, CE and ADC.

Los títulos de crédito como marco de la obra fílmica. Análisis en Un americano en París, West Side Story y El desprecio

Este trabajo de investigación plantea un paralelismo entre los marcos en pintura y lostítulos de crédito en cine. Se analizan los créditos de tres películas (Un americano en París, West Side Story y El desprecio) según sus características de indicación, frontera, límite, umbral al imaginario y marco de actividad. Las películas a las que acompañan pertenecen, a su vez, a diferentes medios de producción y jerarquía, aspectos tecnológicos, áreas estéticas y estructuras de emisión y recepción. Los tres marcos son, a su vez, marcos-objeto, marcos-límite, marcos-ventana y marcos-espejo. Se leen de manera centrípeta, entre dos mundos y desde fuera del marco. Para ello se parte de una metodología transdisciplinar basada en la hermenéutica, el análisis crítico de los textos audiovisuales, los estudios sobrela imagen y el marco como objeto social.

The short arm of the law: judicial institutions and local governance in Brazil

This paper estimates the effect of judicial institutions on governance at the local level in Brazil. Our estimation strategy exploits a unique institutional feature of state judiciary branches which assigns prosecutors and judges to the most populous among contiguous counties forming a judiciary district. As a result of this assignment mechanism there are counties with nearly identical populations, some with and some without local judicial presence, which we exploit to impute counterfactual outcomes. Conditional on observable county characteristics, offenses per civil servant are about 35% lower in counties that have a local seat of the state judiciary. The lower incidence of infractions stems mostly from fewer violations of financial management regulations by local administrators, fewer instances of problems in project execution and project managment, fewer cases of non-existent or ineffective civil society oversight and fewer cases of improper handling of remittances to local residents.

A success story: The rebirth of Iowa’s trout streams, 2007

Practically since settlement of the state, Iowa trout streams had to be stocked to maintain a trout population. But improvements in water quality are leading to healthier, self-sustaining trout populations - and local communities are reaping the benefits.

Development of the short version of the informal caregiver burden assessment questionnaire

OBJETIVE to create a reduced version of the QASCI, which is structurally equivalent to the long one and meets the criteria of reliability and validity. METHOD Through secondary data from previous studies, the participants were divided into two samples, one for the development of reduced version and the second for study of the factorial validity. Participants responded to QASCI, the SF 36, the ADHS and demographic questions. RESULTS A reduced version of 14 items showed adequate psychometric properties of validity and internal consistency, adapted to a heptadimensional structure that assesses positive and negative aspects of care. CONCLUSION Confirmatory factor analysis revealed a good fit with the advocated theoretical model.

A non-randomized direct comparison of cognitive-behavioral short- and long-term treatment for binge eating disorder

Background: To compare treatment outcomes of a cognitive-behavioral long-term (CBT-L) and short-term (CBT-S) treatment for binge eating disorder (BED) in a non-randomized comparison and to identify moderators of treatment outcome. Methods: 76 female patients with BED participated in the study: 40 in CBT-L and 36 in CBT-S. Outcome values were compared at the end of the active treatment phase (16 sessions for CBT-L, 8 sessions for CBT-S) and at 12-month follow-up. Results: Both treatments produced significant reductions in binge eating. At the end of active treatment, but not at the end of follow-up, effects of primary outcomes (e.g. remission from binge eating, EDE shape concern) were better for CBT-L than for CBT-S. Dropout rates were significantly higher in CBT-L (35%) than in CBT-S (14%). Moderator analyses revealed that treatment efficacy for rapid responders and individuals exhibiting high scores on the mixed dietary negative affect subtype differed between the CBT-L and CBT-S with respect to objective binges, restraint eating and eating concern. Conclusion: Findings suggest that CBT in general represents an effective treatment for BED, but that subgroups of patients might profit more from a prolonged treatment. Short, lessintensive CBT treatments could nevertheless be a viable option in the treatment of BED.
