Invasive bladder carcinoma: a pilot study of conservative treatment with accelerated radiotherapy and concomitant cisplatin.

From November 1992 to December 1997, 25 patients (inoperable or refusing cystectomy) were included in a prospective study to assess the feasibility, tolerance, and curative potential of accelerated radiotherapy (RT) and concomitant cisplatin. Median age was 74 years (range 49-86). Stage distribution was as follows: 1 T1, 10 T2, 8 T3, and 6 T4. Two patients had clinically positive pelvic nodes. The goal was to deliver a total dose of 40 Gy to the whole pelvis and bladder in 4 weeks using a concomitant boost of 20 Gy to the tumor or to the whole bladder during the third and fourth weeks (total dose 60 Gy), with daily cisplatin (6 mg/m(2)) before RT for patients with creatinine clearance > 50 ml/min. All but one patient completed the RT protocol. Daily cisplatin was successfully delivered in 18 patients. One patient presented with grade III ototoxicity. Diarrhea was scored grade III in two and grade IV in two patients. Acute urinary toxicity was scored grade III in one patient. Posttreatment late effects included bladder grade II and grade III in two patients and one patient, respectively; large bowel grade III in one; urethral grade III in one; and femoral head radionecrosis in one. Four-year overall and disease-specific survival rates were 23% and 35%, respectively. The latter was 60% for patients with T2 tumors. The 4-year actuarial locoregional control rate for all patients was 61%. In summary, accelerated RT and concomitant cisplatin is feasible with acceptable tolerance even in relatively old patients. Although outcome was better for patients with low-stage tumors, local control and survival rates appeared similar to those of standard RT schedules for a similar patient population.

Mecanismos fisiopatológicos en la rumiación

La fisiopatología del síndrome de rumiación es mal conocida. Por ello, el objetivo del estudio es determinar las características clínicas, fisiológicas y psicopatológicas de los pacientes con rumiación respecto a un grupo de dispepsia funcional. Se estudiaron ambos grupos de forma prospectiva durante dos años, realizándose manometría gastrointestinal y esofágica, vaciamiento gástrico, barostato gástrico y valoración psipatológica. Concluimos que el síndrome de rumiación se presenta en pacientes con características funcionales de dispepsia funcional, sin evidenciarse diferencias en la patología psiquiátrica pero con una mejor percepción de la enfermedad respecto al grupo de dispépticos.

Changes in patterns of practice for prostate cancer radiotherapy in Italy 1995-2003. A survey of the Prostate Cancer Study Group of the Italian Radiation Oncology Society.

Aims and background. In 2002, a survey including 1759 patients treated from 1980 to 1998 established a "benchmark" Italian data source for prostate cancer radiotherapy. This report updates the previous one. Methods. Data on clinical management and outcomes of 3001 patients treated in 15 centers from 1999 through 2003 were analyzed and compared with those of the previous survey. Results. Significant differences in clinical management (-10% had abdominal ma-gnetic resonance imaging; +26% received ≥70 Gy, +48% conformal radiotherapy, -20% pelvic radiotherapy) and in G3-4 toxicity rates (-3.8%) were recorded. Actuarial 5-year overall, disease-specific, clinical relapse-free, and biochemical relapse-free survival rates were 88%, 96%, 96% and 88%, respectively. At multivariate analysis, D'Amico risk categories significantly impacted on all the outcomes; higher radiotherapy doses were significantly related with better overall survival rates, and a similar trend was evident for disease-specific and biochemical relapse-free survival; cumulative probability of 5-year late G1-4 toxicity was 24.8% and was significantly related to higher radiotherapy doses (P <0.001). Conclusions. The changing patterns of practice described seem related to an improvement in efficacy and safety of radiotherapy for prostate cancer. However, the impact of the new radiotherapy techniques should be prospectively evaluated.

An Analysis of black-box optimization problems in reinsurance: evolutionary-based approaches

Black-box optimization problems (BBOP) are de ned as those optimization problems in which the objective function does not have an algebraic expression, but it is the output of a system (usually a computer program). This paper is focussed on BBOPs that arise in the eld of insurance, and more speci cally in reinsurance problems. In this area, the complexity of the models and assumptions considered to de ne the reinsurance rules and conditions produces hard black-box optimization problems, that must be solved in order to obtain the optimal output of the reinsurance. The application of traditional optimization approaches is not possible in BBOP, so new computational paradigms must be applied to solve these problems. In this paper we show the performance of two evolutionary-based techniques (Evolutionary Programming and Particle Swarm Optimization). We provide an analysis in three BBOP in reinsurance, where the evolutionary-based approaches exhibit an excellent behaviour, nding the optimal solution within a fraction of the computational cost used by inspection or enumeration methods.

Estrategias analógicas y sentido del humor en el aprendizaje de la competencia social de los profesionales de la educación social

Exploramos, en este artículo, el desarrollo y los resultados iniciales de una metodología innovadora que, usando la metáfora y el sentido del humor, crea un espacio narrativo en un contexto de formación universitaria en competencia social que favorece el proceso de aprendizaje. La experiencia consiste en vincular un escenario metafórico al escenario académico y al futuro escenario profesional. En el artículo se describen los ingredientes de la metáfora utilizada (la fiesta de cumpleaños) y sus vínculos con las competencias trabajadas en la asignatura de Habilidades sociales en la Facultad de Educación Social y Trabajo Social Pere Tarrés (URL). La valoración del profesorado y de los estudiantes la avala como una práctica educativa de éxito cuyos ingredientes pueden ser generalizados a otros contextos formativos.

Evaluación de la situación del Síndrome de Burnout, Reactividad al Estrés y Calidad de Vida Profesional de los residentes de Anestesiología, Reanimación y Terapéutica del Dolor en Cataluña

Tanto el estrés cómo el Síndrome de Burnout, condicionados por factores demográficos, económicos, sociales y profesionales, afectan especialmente al colectivo médico y sobretodo a residentes. Se recogieron 154 residentes de Anestesiología que cumplimentaron tres cuestionarios : Malasch Burnout Inventory, índice de Reactividad al Estrés y Calidad de Vida Profesional. El 49,3% presentó Agotamiento Emocional alto y el 53,3% alta Despersonalización, presentando Burnout el 66,4%. El 47,9% tenía un Probable Trastorno de Estrés, y su valoración global de Calidad de Vida Profesional fue del 6,17 en una escala del 1 al 10. La incidencia de Burnout entre los residentes de Anestesiología de Cataluña es elevada, y casi la mitad de ellos probablemente padecen un trastorno de estrés.

Satisfacción de las necesidades básicas en la población inmigrante femenina Marroquí en Arteixo

Aunque hace unos años la población inmigrante marroquí era en su mayor parte masculina, cada día aumenta el número de mujeres, colectivo del que se ocupa este trabajo. Conocer cómo afecta la emigración en la satisfacción de las necesidades básicas de Virginia Henderson, qué transformaciones y adaptaciones se tienen que realizar para satisfacerlas y qué reinterpretaciones y estrategias se ponen en marcha para minimizar el impacto del choque cultural. Durante un año 2004-2005 hemos realizado una investigación cualitativa mediante entrevistas semiestructuradas a 20 mujeres musulmanas inmigrantes en un municipio de Galicia (España). En la persona musulmana, toda su vida está regulada por la religión, por lo que las necesidades afectadas están estrechamente relacionadas con la necesidad de actuar según valores y creencias. Por ello, la valoración de dicha necesidad aporta datos fundamentales para orientar las actividades dirigidas a mantener y recuperar la salud.

Node-negative T1-T2 anal cancer: radiotherapy alone or concomitant chemoradiotherapy?

PURPOSE: To evaluate the influence of concomitant chemotherapy on loco-regional control (LRC) and cancer-specific survival (CSS) in patients with T1-T2 N0 M0 anal cancer treated conservatively by primary radiotherapy (RT). MATERIALS AND METHODS: Between 1976 and 2008, 146 patients with T1 (n=29) or T2 (n=117) N0 M0 anal cancer were treated curatively by RT alone (n=71) or by combined chemoradiotherapy (CRT) (n=75) consisting of mitomycin C±5-fluorouracil. Univariate and multivariate analyses were performed to assess patient-, tumor- and treatment-related factors influencing LRC and CSS. RESULTS: With a median follow-up of 62.5 months (interquartilerange, 26-113 months), 122 (84%) patients were locally controlled. The five-year actuarial LRC, CSS and overall survival for the population were 81.4%±3.6%, 91.9%±2.6%, and 75.4%±3.9%, respectively. The five-year LRC and CSS for patients treated with RT alone and with CRT were 75.5%±6.0% vs. 86.8%±4.1% (p=0.155) and 88.5%±4.5% vs. 94.9%±2.9% (p=0.161), respectively. In the multivariate analysis, no clinical or therapeutic factors were found to significantly influence the LRC and CSS, while the addition of chemotherapy was of borderline significance (p=0.065 and p=0.107, respectively). CONCLUSIONS: In the management of node negative T1-T2 anal cancer, LRC and CSS tend to be superior in patients treated by combined CRT, even though the difference was not significant. Randomized studies are warranted to assess definitively the role of combined treatment in early-stage anal carcinoma.

Multivalvular surgery for infective endocarditis.

The short and the long-term results of our experience with 25 consecutive patients who underwent multivalvular surgery for infective endocarditis are analysed. Preoperatively, 20/25 (80%) patients were in New York Heart Association (NYHA) stage III or IV, and 2/25 (8%) patients were in cardiogenic shock. All the diseased valves were replaced with mechanical bileaflet prosthesis except seven mitral valves and one tricuspid valve, which could be repaired. Major postoperative complications occurred in 3/25 (12%) patients: a fatal cerebral haemorrhage, a reversible cerebellar syndrome and an intractable heart failure, which required transplantation. During a mean follow-up of 4.7 years (range 6 months to 16.8 years), 7/25 (28%) patients suffered from valve-related complications: five bleedings (one died), one embolic event and one prosthetic valve thrombosis. The actuarial freedom of valve-related event at 10 years was 61.8 +/- 12.4%. There was no prosthetic endocarditis. At follow-up, 20/21 (95%) survivors were in NYHA stage I or II. Long-term outcome in our patient population operated on for multivalvular endocarditis, is satisfactory with no recurrent infection and excellent functional results.

Utilização de questionários validados para mensurar a adesão ao tratamento da hipertensão arterial: uma revisão integrativa

Este estudo teve como objetivo analisar na produção científica da saúde coletiva quais questionários validados estão sendo utilizados para avaliar a adesão ao tratamento da hipertensão. Trata-se de uma Revisão Integrativa realizada nas bases de dados SciELO, MEDLINE e LILACS. Foram selecionados nove estudos que utilizaram sete questionários: Teste de Moriski-Green, Cuestionário de Valoración de Adherencia, Cuestionário MBG, Questionário QAM-Q, Teste de Haynes, Escala de Conductas em Salud e Hill-Bone compliance Scale. Concluímos que a avaliação da adesão ao tratamento da hipertensão ainda é campo aberto para pesquisa, os diferentes instrumentos utilizados têm suas limitações e não há um método ideal.

Validez de la monitorización neurofisiológica intraoperatoria en la cirugía de columna lumbosacra

Se realizó un estudio con 60 pacientes sometidos a cirugía de raquis lumbosacro estableciendo los criterios de alarma intraoperatorios a valorar: presencia de descargas neurotónicas en la electromiografía de barrido libre continuo y la obtención de respuesta electromiográfica al estimular los tornillos pediculares a menos de 12 mV . Previamente se realizó un estudio electromiográfico preoperatorio y, tras el seguimiento intraoperatorio, una nueva valoración electromiográfica a las 6 semanas de la intervención para objetivar si existían nuevas lesiones. Los resultados planten dudas sobre el valor-efectividad de la electromiografía de barrido libre y la electromiogafía estimulada (tornillos) refuerza la revisión radiológica.
