Individual versus standard quality of life assessment in a phase II clinical trial in mesothelioma patients: feasibility and responsiveness to clinical changes.

BACKGROUND: In patients with malignant pleural mesothelioma undergoing a multimodality therapy, treatment toxicity may outweigh the benefit of progression-free survival. The subjective experience across different treatment phases is an important clinical outcome. This study compares a standard with an individual quality of life (QoL) measure used in a multi-center phase II trial. PATIENTS AND METHODS: Sixty-one patients with stage I-III technically operable pleural mesothelioma were treated with preoperative chemotherapy, followed by pleuropneumonectomy and subsequent radiotherapy. QoL was assessed at baseline, at day 1 of cycle 3, and 1, 3 and 6 months post-surgery by using the Rotterdam Symptom Checklist (RSCL) and the Schedule for the Evaluation of Quality of Life-Direct Weighting (SEIQoL-DW), a measure that is based on five individually nominated and weighted QoL-domains. RESULTS: Completion rates were 98% (RSCL) and 92% (SEIQoL) at baseline and 98%/89% at cycle 3, respectively. Of the operated patients (N=45) RSCL and SEIQoL were available from 86%/72%, 93%/74%, and 94%/76% at months 1, 3, and 6 post-surgery. Average assessment time for the SEIQoL was 24min compared to 8min needed for the RSCL. Median changes from baseline indicate that both RSCL QoL overall score and SEIQoL index remained stable during chemotherapy with a clinically significant deterioration (change>or=8 points) 1 month after surgery (median change of -66 and -14 for RSCL and SEIQoL, respectively). RSCL QoL overall scores improved thereafter, but remained beneath baseline level until 6 months after surgery. SEIQoL scores improved to baseline-level at month 3 after surgery, but worsened again at month 6. RSCL QoL overall score and SEIQoL index were moderately correlated at baseline (r=.30; p<or=.05) and at 6-month follow-up (r=.42; p<or=.05) but not at the other time points. CONCLUSION: The SEIQoL assessment seems to be feasible within a phase II clinical trial, but may require more effort from staff. More distinctive QoL changes in accordance with clinical changes were measured with the RSCL. Our findings suggest that the two measures are not interchangeable: the RSCL is to favor when mainly information related to the course of disease- and treatment is of interest.

Quality assurance in the EORTC 22033-26033/CE5 phase III randomized trial for low grade glioma: the digital individual case review.

INTRODUCTION: The phase III EORTC 22033-26033/NCIC CE5 intergroup trial compares 50.4 Gy radiotherapy with up-front temozolomide in previously untreated low-grade glioma. We describe the digital EORTC individual case review (ICR) performed to evaluate protocol radiotherapy (RT) compliance. METHODS: Fifty-eight institutions were asked to submit 1-2 randomly selected cases. Digital ICR datasets were uploaded to the EORTC server and accessed by three central reviewers. Twenty-seven parameters were analysed including volume delineation, treatment planning, organ at risk (OAR) dosimetry and verification. Consensus reviews were collated and summary statistics calculated. RESULTS: Fifty-seven of seventy-two requested datasets from forty-eight institutions were technically usable. 31/57 received a major deviation for at least one section. Relocation accuracy was according to protocol in 45. Just over 30% had acceptable target volumes. OAR contours were missing in an average of 25% of cases. Up to one-third of those present were incorrectly drawn while dosimetry was largely protocol compliant. Beam energy was acceptable in 97% and 48 patients had per protocol beam arrangements. CONCLUSIONS: Digital RT plan submission and review within the EORTC 22033-26033 ICR provide a solid foundation for future quality assurance procedures. Strict evaluation resulted in overall grades of minor and major deviation for 37% and 32%, respectively.

A continuació es tracta el treball, revelant la situació del mercat a l’actualitat, també per als immigrants i sense oblidar el fenomen de l’atur i de les repercussions psicològiques que s’hi deriven. Finalment tractarem el tema de la dona; la seva evolució a la societat, al mercat de treball, el lideratge i també el paper de la dona immigrant al món professional i quina relació existeix entre aquests dos grups de dones.

Development and growth of the early juveniles of the spider crab Maja squinado (Brachyura: Majoidea) in an individual culture system

The spider crab Maja squinado is an endangered Mediterranean species; therefore, culturing it successfully is essential for developing restocking programs. The survival, growth and development of post-larval stages (juvenile crabs, C1-C8) were studied using larvae obtained from adult individuals collected in the Catalan Sea. The juvenile crab stages were cultured individually from a megalopal stage using a semi-open recirculation system to obtain the precise growth data of each juvenile crab stage until C8. Development up to C8 at 20ºC lasted 154±10 days. Survival from C1 to C8 was 5.8 %. Moult increment values in cephothoracic length were similar in all the crab stages (21-35 %). Intermoult duration (9±1 in C1-C2 to 51±8 days in C7-C8) increased sharply from juvenile stage 5. Males and females can be distinguished from C4 based on sexual dimorphism in the pleopods and the presence of gonopores. The allometric growth of the pleon is sex-dependent from C4, with females showing positive allometry and males isometric growth. The juvenile growth rate was lower compared with that of the previously studied Atlantic species Maja brachydactyla.

Nasopharyngeal carriage of individual Streptococcus pneumoniae serotypes during pediatric radiologically confirmed community acquired pneumonia following PCV7 introduction in Switzerland.

BACKGROUND: Community-acquired pneumonia (CAP) is a serious cause of morbidity among children in developed countries. The real impact of 7-valent pneumococcal conjugate vaccine (PCV7) on pneumococcal pneumonia is difficult to assess accurately. METHODS: Children aged ≤16 years with clinical and radiological pneumonia were enrolled in a multicenter prospective study. Children aged ≤16 years admitted for a minor elective surgery was recruited as controls. Nasopharyngeal samples for PCR serotyping of S. pneumoniae were obtained in both groups. Informations on age, gender, PCV7 vaccination status, day care/school attendance, siblings, tobacco exposure were collected. RESULTS: In children with CAP (n=236), 54% of the nasopharyngeal swabs were PCR-positive for S. pneumoniae compared to 32% in controls (n=105) (p=0.003). Serotype 19A was the most common pneumococcal serotype carried in children with CAP (13%) and in controls (15%). Most common serotypes were non-vaccine types (39.4% for CAP and 47.1% for controls) and serotypes included only in PCV13 (32.3% for CAP and 23.5% for controls). There was no significant difference in vaccine serotype distribution between the two groups. In fully vaccinated children with CAP, the proportion of serotypes carried only in PCV13 was higher (51.4%) than in partially vaccinated or non vaccinated children (27.6% and 28.6% respectively, p=0.037). CONCLUSIONS: Two to 4 years following introduction of PCV7, predominant S. pneumoniae serotypes carried in children with CAP were non PCV7 serotypes, and the 6 new serotypes included in PCV13 accounted for 51.4% of carried serotypes in fully vaccinated children.

Validación de la escala modificada de MASCC y papel de los marcadores biológicos en la estratificación del riesgo individual del paciente con fiebre neutropénica inducida por quimioterapia y neoplasia sódia

Estudi prospectiu d’incidència de NF degut a la QT a pacients amb neoplàsia solida. S’estudia la validació de l’escala modificada de MASCC i utilitat de marcadors d’inflamació en l’estratificació del risc individual. Hem inclòs 54 episodis de NF. El 50% (27/54) va ser de baix risc. Predomini de BGN (73,3%). 13% van ser bacterièmics. La sensibilitat i especificitat de l’escala modificada de MASCC van ser del 56% i 54%, respectivament. El recompte baix de granulòcits prediuen bacterièmia; i els nivells baixos de IL-12, alts de PCR i de proADM, i el temps curt de neutropènia al desenvolupament de complicacions i/o de mort. L’escala modificada de MASCC va obtenir una baixa sensibilitat i especificitat. El recompte de granulòcits, nivells de PCR i proADM s’haurien d’incloure a l’escala clàssica de MASCC per incrementar la seva sensibilitat i especificitat.

Las Imágenes del malestar. Representaciones del yo y la construcción de subjetividad en la producción audiovisual contemporánea y en los nuevos dispositivos tecnológicos

El tema de la investigación propuesto aquí, se centra en el malestar social, y la representación de éste desde un punto de vista personal y autobiográfico, algo que en estas página denomino Autorepresentación del malestar social. ¿Cómo se autorepresenta el malestar y qué prácticas artísticas se emplean para ello? ¿Cuáles son la transformaciones que provocan estas prácticas artísticas en el terreno audiovisual? En este sentido, exploraremos dos vías de análisis: por un lado nos interesa observar cuales han sido las modificaciones que el poder ha desarrollado para establecer nuevas formas de explotación, y por otro lado, veremos como estas modificaciones están generando una nueva praxis social donde las prácticas artísticas cobran un nuevo y reforzado sentido, así como una nueva capacidad política, individual y colectiva a un mismo tiempo, cargada de una fuerza transformadora capaz de componer nuevos espacios de sujeto. Analizaremos, desde la representación del yo en la vida cotidiana, el género y las relaciones interpersonales, hasta las transformaciones contemporáneas del trabajo, y los cambios en la construcción de la subjetividad. El principal elemento en el que se apoyaran nuestras investigaciones será el anàlisis de producciones audiovisuales contemporáneas y la distribución de estas en algunas de las redes de comunicación contemporáneas, intentando mostrar, de esta manera, la interacción y los efectos directos que provocan en la realidad social.

Influence of Individual Characteristics on Work Engagement and Job Stress in a Sample of National and Foreign Workers in Switzerland

In most Western postindustrial societies today, the population is aging, businesses are faced with global integration, and important migration flows are taking place. Increasingly work organizations are hiring crossnational and multicultural workteams. In this situation it is important to understand the influence of certain individual and cultural characteristics on the process of professional integration. The present study explores the links between personality traits, demographic characteristics (age, sex, education, income, and nationality), work engagement, and job stress. The sample consisted of 618 participants, including 394 Swiss workers (200 women, 194 men) and 224 foreigners living and working in Switzerland (117 women, 107 men). Each participant completed the NEO-FFI, the UWES, and the GWSS questionnaires. Our results show an interaction between age and nationality with respect to work engagement and general job stress. The levels of work engagement and job stress appear to increase with age among national wotkers, whereas they decrease among foreign workers. In addition, work engagement was negatively associated with Neuroticism and positively with the other four personality dimensions. Finally, job stress was positively associated with Neuroticism and Conscientiousness, and negatively associated with Extraversion. However, the strength of these relationships appeared to vary according to the worker's nationality, age, sex, education, and income.

Variability of North Atlantic hurricanes: seasonal versus individual-event features

Tropical cyclones are affected by a large number of climatic factors, which translates into complex patterns of occurrence. The variability of annual metrics of tropical-cyclone activity has been intensively studied, in particular since the sudden activation of the North Atlantic in the mid 1990’s. We provide first a swift overview on previous work by diverse authors about these annual metrics for the North-Atlantic basin, where the natural variability of the phenomenon, the existence of trends, the drawbacks of the records, and the influence of global warming have been the subject of interesting debates. Next, we present an alternative approach that does not focus on seasonal features but on the characteristics of single events [Corral et al., Nature Phys. 6, 693 (2010)]. It is argued that the individual-storm power dissipation index (PDI) constitutes a natural way to describe each event, and further, that the PDI statistics yields a robust law for the occurrence of tropical cyclones in terms of a power law. In this context, methods of fitting these distributions are discussed. As an important extension to this work we introduce a distribution function that models the whole range of the PDI density (excluding incompleteness effects at the smallest values), the gamma distribution, consisting in a powerlaw with an exponential decay at the tail. The characteristic scale of this decay, represented by the cutoff parameter, provides very valuable information on the finiteness size of the basin, via the largest values of the PDIs that the basin can sustain. We use the gamma fit to evaluate the influence of sea surface temperature (SST) on the occurrence of extreme PDI values, for which we find an increase around 50 % in the values of these basin-wide events for a 0.49 C SST average difference. Similar findings are observed for the effects of the positive phase of the Atlantic multidecadal oscillation and the number of hurricanes in a season on the PDI distribution. In the case of the El Niño Southern oscillation (ENSO), positive and negative values of the multivariate ENSO index do not have a significant effect on the PDI distribution; however, when only extreme values of the index are used, it is found that the presence of El Niño decreases the PDI of the most extreme hurricanes.

Cos i espiritualitat : in-corporant rituals i creences en les noves formes de religiositat

El fenomen de les noves religions posa de relleu la importància del cos i les emocions com a elements constitutius de la subjectivitat. En aquest treball s'estudia el procés de construcció de la identitat espiritual, a través de la in-corporació de nous valors i creences, i de la corporeïtzació dels rituals. Es parteix d'una aproximació etnogràfica, a través d'un treball de camp al sí d'un grup d'orientació oriental. A partir de l'observació participant i la celebració d'entrevistes, es proposa analitzar com es forja l'espiritualitat. En tant que experiència corporal, es posa de manifest la rellevància de les emocions en els processos d'interacció i socialització de la persona en un grup donat.

Entre el Gulag y el supermercado : en busca de Alexander Zinoviev

Aquest treball, que còpia en part el títol del llibre de Symons, intenta configurar-se també sobre un doble plànol expositiu. El priemr pla el primer objectiu-, es el més obvi: oferir un panorama del contingut de les principals obres d'un autor, Alexander Zinoviev, i tractar de contextualitzar-les (efectuant per allò incursions al pensament d'altres autors - a mode de breus razzies predatòries). Però el treball aspira a incloure una segona trama: l'intent d'observar una trajectòria intel·lectual determinada -en aquest cas, la de Zinoviev- de d'una certa distància i esbrinar si pot extreure's alguna lliçó no ja de les teories que l'autor va consignar per escrit, sinó de l'actitud existencial i intel·lectual amb la que un individu es va enfrontar als cataclismes produïts pels successius derrumbaments i encumbraments de les grans ideologies de la seva època.
