Five-year quality of life in patients with high-risk localized prostate cancer treated with external beam radiotherapy alone versus external beam radiotherapy with high-dose-rate brachytherapy boost: a prospective multicenter study
(Polish Brachytherapy Society, 2021-02-18) Martinez, Evelyn; Garín, Olatz; Pardo, Yolanda; Fernández, Pablo, 1957-; Guix Melcior, Benjamín; Gutiérrez Miguélez, Cristina; Boladeras, Ana; Ferrer, Ferran; Hernández, Tania; Ayala Gil, Adriana; Egiguren, Mikel; Fernández, Gema; Muñoz, Víctor; Macías, Víctor; Pera Fàbregas, Joan; Pont, Angels; Ferrer García, Montserrat; Guedea Edo, Ferran
Purpose: Brachytherapy (BT) and external beam radiation therapy (EBRT) are effective treatments for high-risk prostate cancer (PCa). However, the impact of these treatments on health-related quality of life (HRQL) remains unclear. In this study, we compared EBRT alone with EBRT plus a boost with high-dose rate (HDR)-BT to determine the impact on HRQL in patients with high-risk PCa. Material and methods: Prospective, multicenter study comparing patients with high-risk PCa treated with EBRT alone or EBRT + HDR-BT from 2004 to 2006. HRQL was assessed at baseline (pre-treatment) and periodically over the 5-year follow-up, using the SF-36 (v.2), EPIC, and FACT-G and FACT-P questionnaires. Results: A total of 129 patients were included in the study, of these, 41 received EBRT alone and 88 EBRT + HDR-BT. All patients received hormonotherapy. Baseline clinical characteristics were similar, except for a slightly higher mean number of comorbidities in the EBRT group. During follow-up, the only significant between-group difference was a greater worsening on EPIC hormonal domain in the EBRT alone group (p = 0.028). There were no significant differences in time and interaction of treatment in SF-36, and FACT-G and FACT-P questionnaires or EPIC urinary incontinence, urinary irritative-obstructive, and bowel and sexual domains over the 5-year follow-up. Oncological outcomes were similar in both groups. Conclusions: After five years of follow-up, EBRT alone or combined with HDR-BT boost had a similar impact on HRQL in patients with high-risk localized PCa. However, patients in the EBRT alone group experienced greater wors ening of hormonal domain according to EPIC questionnaire.
Programa: Aprendre junts, créixer en família
(GRISIJ. Universitat de Barcelona, 2026-07) Fuentes-Peláez, Núria; Mateos Inchaurrondo, Ainoa; Parra Ramajo, Belén; Rabassa, Judit
El document presenta una revisió de quatre programes de suport a la parentalitat basats en evidències, elaborada per l’Equip de formació en metodologia grupal i parentalitat positiva (Fuentes-Peláez, Mateos, Parra i Rabassa, juliol de 2026). L’objectiu és oferir una síntesi d’intervencions contrastades orientades a reforçar les competències parentals i a promoure el benestar infantil i familiar.
Income-Based Directional Price Discrimination Evidence from European Airline Markets
(2026) Brunner, Joshua Francisco; Calzada, Joan ; Fageda, Xavier, 1975-
This paper investigates income-based directional price discrimination on international airline routes. I construct a real-time dataset of directional fare differences for major European hub airports between February and July 2026 and compare mirrored roundtrips using matching strategies that either assign passengers to the same physical flight components or create closely matched counterfactual fares. The results show that passengers originating in higher-income markets systematically pay higher fares than passengers originating in lower-income markets. In the baseline national GDP specification, a 10,000 USD increase in the income difference raises the directional fare premium by approximately 3.00 to 3.43 USD. The dynamic specifications indicate that this premium tends to become larger in shorter booking windows, especially when the comparison isolates the same underlying flight components. The results also show that the income premium decreases with the number of effective competitors, suggesting that income-based directional fare premia are a signal of airline market power.
Investigació de la identitat adolescent a través delcolor i els referents visuals
(2026) Pérez Gutiérrez, Adrià; Mesas Quero, Sheila
[cat] Aquest Treball Final de Màster se centra en el Batxillerat Artístic i explora la relació entre l’aprenentatge tècnic del color i l’expressió identitària de l’alumnat. Davant la tendència a treballar els continguts tècnics del llenguatge visual des d’una perspectiva desconnectada dels interessos personals dels estudiants, es planteja una intervenció didàctica que integra la teoria del color amb la investigació de referents visuals i culturals propis. A través d’una metodologia que combina sessions expositives, experimentació pictòrica i desenvolupament d’una obra final, l’alumnat posa en pràctica els coneixements tècnics adquirits en un procés de presa de decisions visuals vinculat a la construcció del seu imaginari personal. El projecte culmina en l’exposició i comunicació del procés creatiu, reforçant la dimensió comunicativa de la pràctica artística. El treball analitza fins a quin punt la integració entre coneixement tècnic i exploració personal pot afavorir la motivació, la implicació i el desenvolupament d’un discurs visual propi en el context educatiu artístic. [eng] This Master’s Final Project focuses on the Artistic Baccalaureate and explores the relationship between the technical learning of color and the students' expression of identity. Given the prevailing tendency to approach the technical contents of visual language from a perspective disconnected from the personal interests of the students, a didactic intervention is proposed that integrates color theory with the investigation of their own visual and cultural referents.Through a methodology that combines expository sessions, pictorial experimentation, and the development of a final work, students put into practice the acquired technical knowledge within a process of visual decision-making linked to the construction of their personal imaginary. The project culminates in the exhibition and communication of the creative process, reinforcing the communicative dimension of artistic practice. This work analyzes to what extent the integration of technical knowledge and personal exploration can foster motivation, engagement, and the development of a personal visual discourse within the context of artístic education.
