Seminoma arising in corrected and uncorrected inguinal cryptorchidism: treatment and prognosis in 66 patients.

PURPOSE: The purpose of this study was to analyze prognosis and treatment results for seminoma arising in corrected and uncorrected inguinal cryptorchidism (SCIC and SUIC). METHODS AND MATERIALS: We reviewed 66 patients with inguinal seminomas between June 1958 and December 1991 at the Cancer Hospital and Institute of Chinese Academy of Medical Sciences. Of these patients, 23 had prior orchiopexy and 43 presented with an inguinal form of cryptorchidism. At presentation, 17 of 66 (26%) patients had nodal metastases. This nodal involvement was 30% (7 of 23) for SCIC and 23% (10 of 43) for SUIC, respectively. These numbers are comparable with those in a series of patients treated for scrotal seminoma at our institution (26% vs. 20%). However, 3 of 23 (13%) patients who had prior orchiopexy presented with inguinal nodal metastasis as compared with 0 of 43 patients with SUIC or 4 of 237 patients with scrotal seminoma (p < .05). There were 49 stage I, 5 stage IIA, 8 stage IIB, 3 stage III, and 1 stage IV patients. All patients underwent radical orchiectomy and received further radiotherapy, chemotherapy, or both. Patients with stage I and stage II disease were treated primarily with radiotherapy, whereas patients with stage III and IV disease were treated with chemotherapy. RESULTS: The overall and disease-free survival at 5 and 10 years was 94% and 92%, 89% and 87%, respectively. The overall 5- and 10-year survival by stage was 100% and 100% for stage I, and 77% and 68% for stage II, respectively (p < .05). There was no significant difference in survival between SUIC and SCIC (93% vs. 96% at 5 years). Four patients developed relapse. Two of these four patients experienced relapse at the inguinal area, due to a marginal miss. Three of four patients with relapse were successfully salvaged, and one died of disease. CONCLUSION: Our results indicate that prognosis for inguinal seminoma is excellent and similar to that of scrotal seminoma. Postorchiectomy radiotherapy can be considered as the standard treatment for stage I and IIA inguinal seminoma. We recommend routinely including the para-aortic and ipsilateral pelvic nodes.

Herdabilidade e correlações quanto a peso, perímetro escrotal e escores visuais à desmama, em bovinos Canchim

O objetivo deste trabalho foi estabelecer o modelo mais adequado para avaliação genética de bovinos Canchim e estimar os parâmetros genéticos de características produtivas à desmama. Foram utilizados dados de: 12.103 animais, quanto ao peso (PD); 5.278, quanto ao perímetro escrotal (PE); 8.343, quanto ao escore visual da conformação frigorífica (CF); 9.111, quanto ao escore de umbigo (UM); e 7.986, quanto ao escore de pelame (PEL). Os modelos estatísticos incluíram os efeitos fixos e os efeitos aleatórios genéticos aditivos direto, materno e de ambiente permanente materno, em diferentes combinações. As análises foram feitas pelo método da máxima verossimilhança restrita livre de derivadas. O modelo completo foi o mais adequado para PD, PE, CF e UM, enquanto o modelo com uso apenas dos efeitos genéticos aditivos direto e materno foi o mais adequado para PEL. As estimativas de herdabilidade direta foram 0,17, 0,13, 0,20, 0,18, e 0,52 para PD, PE, CF, UM e PEL, respectivamente, o que indica a possibilidade de se obter progresso genético por meio da seleção para essas características, principalmente para PEL. As correlações genéticas aditivas diretas entre as características variaram de -0,16 a 0,61. As correlações entre PD e PE e entre PD e CF indicam que a seleção para PD deve proporcionar ganho genético em PE e CF

An overview of the metabolic differences between Bradyrhizobium japonicum 110 bacteria and differentiated bacteroids from soybean (Glycine max) root nodules: an in vitro 13C- and 31P-nuclear magnetic resonance spectroscopy study.

Bradyrhizobium japonicum is a symbiotic nitrogen-fixing soil bacteria that induce root nodules formation in legume soybean (Glycine max.). Using (13)C- and (31)P-nuclear magnetic resonance (NMR) spectroscopy, we have analysed the metabolite profiles of cultivated B. japonicum cells and bacteroids isolated from soybean nodules. Our results revealed some quantitative and qualitative differences between the metabolite profiles of bacteroids and their vegetative state. This includes in bacteroids a huge accumulation of soluble carbohydrates such as trehalose, glutamate, myo-inositol and homospermidine as well as Pi, nucleotide pools and intermediates of the primary carbon metabolism. Using this novel approach, these data show that most of the compounds detected in bacteroids reflect the metabolic adaptation of rhizobia to the surrounding microenvironment with its host plant cells.

Prestacions en benefici de la comunitat i realització de tasques socioeducatives en justícia juvenil

Els joves als quals se’ls ha imposat una mesura de realització de tasques socioeducatives (RTS) o de prestacions en benefici de la comunitat (PBC) presenten un alt fracàs escolar, majoritàriament amb baix rendiment i abandonament dels estudis en la meitat dels casos. Un de cada tres joves prové d’una família amb algun tipus de problemàtica específica o una economia insuficient. Els resultats indiquen, però, que els joves que realitzen tasques socioeducatives solen acumular més problemàtiques que els de PBC, ja sigui a nivell personal, familiar o social. Quant al perfil penal i criminològic, el 63% dels nois i noies d’aquestes dues mesures té antecedents. La taxa de reincidència de RTS és del 31,1% i la de PBC del 25,2%. Alguns dels factors que els joves reincidents mostren en més proporció són tenir un grup d’iguals dissocial, estar en contacte amb els serveis socials o tenir antecedents. Els reincidents de RTS també presenten més proporció de consum de tòxics, problemes de salut mental, fracàs escolar i una ocupació del temps desestructurada i amb conductes de risc. Comparant aquests resultats amb estudis respecte altres programes i mesures de Justícia juvenil podem concloure que la taxa de reincidència global a Catalunya és del 28,9% i l’específica de Medi obert és del 27,8%.

Sensitivity of single-voxel 1H-MRS in investigating the metabolism of the activated human visual cortex at 7 T.

Proton magnetic resonance spectroscopy (1H-MRS) has been used in a number of studies to noninvasively assess the temporal changes of lactate in the activated human brain. However, the results have not been consistent. The aim of the present study was to test the sensitivity of 1H-MRS during functional experiments at the highest magnetic field currently available for human studies (7 T). Stability and reproducibility of the measurements were evaluated from LCModel analysis of time series of spectra measured during a visual stimulation paradigm and by examination of the difference between spectra obtained at rest and during activation. The sensitivity threshold to detect concentration changes was 0.2 micromol/g for most of the quantified metabolites. The possible variations of metabolite concentrations during visual stimulation were within the same range (+/-0.2 micromol/g). In addition, the influence of a small line-narrowing effect due to the blood oxygenation level-dependent (BOLD) T2* changes on the estimated concentrations was simulated. Quantification of metabolites was, in general, not affected beyond 1% by line-width changes within 0.5 Hz.

Radiotherapy and temozolomide for newly diagnosed glioblastoma: recursive partitioning analysis of the EORTC 26981/22981-NCIC CE3 phase III randomized trial.

PURPOSE: The European Organisation for Research and Treatment of Cancer and National Cancer Institute of Canada trial on temozolomide (TMZ) and radiotherapy (RT) in glioblastoma (GBM) has demonstrated that the combination of TMZ and RT conferred a significant and meaningful survival advantage compared with RT alone. We evaluated in this trial whether the recursive partitioning analysis (RPA) retains its overall prognostic value and what the benefit of the combined modality is in each RPA class. PATIENTS AND METHODS: Five hundred seventy-three patients with newly diagnosed GBM were randomly assigned to standard postoperative RT or to the same RT with concomitant TMZ followed by adjuvant TMZ. The primary end point was overall survival. The European Organisation for Research and Treatment of Cancer RPA used accounts for age, WHO performance status, extent of surgery, and the Mini-Mental Status Examination. RESULTS: Overall survival was statistically different among RPA classes III, IV, and V, with median survival times of 17, 15, and 10 months, respectively, and 2-year survival rates of 32%, 19%, and 11%, respectively (P < .0001). Survival with combined TMZ/RT was higher in RPA class III, with 21 months median survival time and a 43% 2-year survival rate, versus 15 months and 20% for RT alone (P = .006). In RPA class IV, the survival advantage remained significant, with median survival times of 16 v 13 months, respectively, and 2-year survival rates of 28% v 11%, respectively (P = .0001). In RPA class V, however, the survival advantage of RT/TMZ was of borderline significance (P = .054). CONCLUSION: RPA retains its prognostic significance overall as well as in patients receiving RT with or without TMZ for newly diagnosed GBM, particularly in classes III and IV.

Factores de riesgo de conducta violenta intrainstitucional en internos penitenciarios

Este estudio tiene por objeto la determinación de la prevalencia y las correlaciones asociadas a las infracciones disciplinarias violentas y potencialmente violentas de 11 centros penitenciarios de Cataluña. Para alcanzar este objetivo el presente estudio prospectivo, basado en datos oficiales, examina la relación entre variables sociodemográficas, criminales, penitenciarias y psicológicas de una muestra de 7517 internos/as durante un período de seguimiento de 2 años. Los resultados obtenidos indican que ser más joven, estar en situación de prisión preventiva en el caso de las mujeres, haber presentado conducta violenta o antisocial anteriormente, tanto en la comunidad como en el ámbito penitenciario, responder de una manera poco exitosa a los tratamientos recientes o mostrar problemas en el consumo de alcohol o drogas y las actitudes procriminales son factores de gran potencia en la predicción de infracciones disciplinarias. Para concluir, cabe mencionar que investigaciones adicionales en otras áreas geográficas y la consideración de variables situacionales son necesarias para corroborar los resultados aquí obtenidos. También se discuten algunas implicaciones para políticas penitenciarias y para futuras líneas de investigación.

Avaluació del programa de mediació penal d’adults del Departament de Justícia de Catalunya

Des de 1999, el Departament de Justícia aplica el Programa de mediació penal amb infractors adults i víctimes. Aquest Programa, emmarcat en la perspectiva de l’anomenada Justícia Restaurativa, cerca resoldre el conflicte produït pel delicte implicant totes les parts i concedint un paper clau a la víctima, sobre la restitució de la qual gira el procés mediador. La recerca que es presenta fa una avaluació del funcionament d’aquest Programa amb l’objectiu de constatar si la mediació penal pot satisfer algunes de les necessitats de les víctimes de delictes. La valoració que en fan les víctimes que han participat en l’estudi d’avaluació és positiva. Els principals beneficis que destaquen són la reparació material, rebre les disculpes de l’infractor, poder explicar la seva vivència i sentir-se escoltades, i poder participar en la resolució del seu propi procediment i en la resolució final del conflicte.
