- Findings We identified 76 RCTs, including 48 trials contributing individual participant data (11 704 participants) and 28 trials with aggregate data (6474 participants). The participants' weighted mean age was 42.0 years and 12 406 (71%) of 17 521 reported were women. There was suggestive evidence that behavioural activation might be beneficial (iMD -1.83 [95% credible interval (CrI) -2.90 to -0.80]) and that relaxation might be harmful (1.20 [95% CrI 0.17 to 2.27]). Baseline severity emerged as the strongest prognostic factor for endpoint depression. Combining human and automated encouragement reduced dropouts from treatment (incremental odds ratio, 0.32 [95% CrI 0.13 to 0.93]). The risk of bias was low for the randomisation process, missing outcome data, or selection of reported results in most of the included studies, uncertain for deviation from intended interventions, and high for measurement of outcomes. There was moderate to high heterogeneity among the studies and their components. 511

- We describe the mission concept of how ESA can make a major contribution to the Japanese Canadian multi-spacecraft mission SCOPE by adding one cost-effective spacecraft EIDO (Electron and Ion Dynamics Observatory), which has a comprehensive and optimized plasma payload to address the physics of particle acceleration. The combined mission EIDOSCOPE will distinguish amongst and quantify the governing processes of particle acceleration at several important plasma boundaries and their associated boundary layers: collisionless shocks, plasma jet fronts, thin current sheets and turbulent boundary layers. Particle acceleration and associated cross-scale coupling is one of the key outstanding topics to be addressed in the Plasma Universe. The very important science questions that only the combined EIDOSCOPE mission will be able to tackle are: 1) Quantitatively, what are the processes and efficiencies with which both electrons and ions are selectively injected and subsequently accelerated by collisionless shocks? 2) How does small-scale electron and ion acceleration at jet fronts due to kinetic processes couple simultaneously to large scale acceleration due to fluid (MHD) mechanisms? 3) How does multi-scale coupling govern acceleration mechanisms at electron, ion and fluid scales in thin current sheets? 4) How do particle acceleration processes inside turbulent boundary layers depend on turbulence properties at ion/electron scales? EIDO particle instruments are capable of resolving full 3D particle distribution functions in both thermal and suprathermal regimes and at high enough temporal resolution to resolve the relevant scales even in very dynamic plasma processes. The EIDO spin axis is designed to be sun-pointing, allowing EIDO to carry out the most sensitive electric field measurements ever accomplished in the outer magnetosphere. Combined with a nearby SCOPE Far Daughter satellite, EIDO will form a second pair (in addition to SCOPE Mother-Near Daughter) of closely separated satellites that provides the unique capability to measure the 3D electric field with high accuracy and sensitivity. All EIDO instrumentation are state-of-the-art technology with heritage from many recent missions. The EIDOSCOPE orbit will be close to equatorial with apogee 25-30 RE and perigee 8-10 RE. In the course of one year the orbit will cross all the major plasma boundaries in the outer magnetosphere; bow shock, magnetopause and magnetotail current sheets, jet fronts and turbulent boundary layers. EIDO offers excellent cost/benefits for ESA, as for only a fraction of an M-class mission cost ESA can become an integral part of a major multi-agency L-class level mission that addresses outstanding science questions for the benefit of the European science community.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: Early trials have reported a beneficial effect from tamoxifen treatment in patients with unresectable pancreatic cancer, in particular in women. However, the presence and prognostic significance of female hormone receptors in pancreatic or other periampullary cancers has not yet been described. Methods: Immunohistochemical screening of normal and malignant pancreatic tissue revealed that the predominantly expressed female hormone receptor was the progesterone receptor (PgR), in particular in the cancer-associated stroma. The impact of PgR expression on overall survival (OS) was further examined on tissue microarrays with primary tumours from a consecutive retrospective cohort of 175 patients with resected periampullary adenocarcinoma. Results: Median follow-up time was 29.7 (range 1.9–185.1) months. Stromal PgR positivity (PgR+), allover denoted in 31% of the cases, was significantly higher in pancreatobiliary-type than in intestinal-type tumours (38.7% vs 19.0%, p = 0.008), with an equal distribution between sexes. Stromal PgR+ was significantly associated with a prolonged OS in KRAS-mutated tumours, whereas the opposite was seen in KRAS wild-type tumours (p for interaction =0.015). This association was particularly evident in women, with a median OS of 60.5 months for PgR+/KRAS mutated tumours and 9.9 months for PgR+/KRAS wild-type tumours (p for interaction <0.001). PgR expression was not prognostic in male patients. Conclusions: The finding of stromal PgR expression, and its link to clinical outcome in a considerable proportion of pancreatic and other periampullary cancers is novel. The concept of tamoxifen treatment for patients with unresectable disease, in particular elderly women, should be pursued, and PgR and KRAS may be relevant biomarkers for improved patient stratification.

Parametric improvement for the ingestion dose module of the European ARGOS and RODOS decision support systems

Tidskriftsartikel (refereegranskat)abstract
- The European decision support systems ARGOS and RODOS rely on the ECOSYS model for prognoses of ingestion doses. ECOSYS needs an update of various parameter values to provide reliable estimates. This paper reports on some results of a Nordic initiative to derive parameter values that are specific to Nordic conditions, as well as to improve generic parameter values in ECOSYS, taking into account the host of useful measurement data accumulated since ECOSYS was created. © 2011 EDP Sciences.
