Tidskriftsartikel (refereegranskat)abstract
- This report is based on 1.851 adult patients with soft tissue sarcoma (STS) of the extremities or trunk wall diagnosed between 1986 and 1997 and reported from all tertiary referral centers in Norway and Sweden. The median age at diagnosis was 65 years and the male-to-female ratio was 1.1:1. One third of the tumors were subcutaneous, one third deep, intramuscular and one third deep, extramuscular. The median size was 7 (1-35) cm and 75% were high grade (III-IV). Metastases at presentation were diagnosed in 8% of the patients. Two thirds of STS patients were referred before surgery and the referral practices have improved during the study. The preoperative morphologic diagnosis was made with fine-needle aspiration cytology in 81%, core-needle biopsy in 9% and incisional biopsy in 10%. The frequency of amputations has decreased from 15% in 1986-88 to 9% in 1995-1997. A wide surgical margin was achieved in 77% of subcutaneous and 60% of deep-seated lesions. Overall, 24% of operated STS patients had adjuvant radiotherapy. The use of such therapy at sarcoma centers increased from 20% 1986-88 to 30% in 1995-97. Follow-up has been reported in 96% of the patients. The cumulative local recurrence rate was 0.20 at 5 years and 0.24 at 10 years. The 5-year metastasis-free survival rate was 0.70.

Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty

- This study explores how researchers analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions as they used the same data to independently test the same prominent social science hypothesis: that greater immigration reduces support for social policies among the public. In this typical case of social science research, research teams reported both widely diverging numerical findings and substantive conclusions despite identical start conditions. Researchers expertise, prior beliefs, and expectations barely predict the wide variation in research outcomes. More than 95% of the total variance in numerical results remains unexplained even after qualitative coding of all identifiable decisions in each teams workflow. This reveals a universe of uncertainty that remains hidden when considering a single study in isolation. The idiosyncratic nature of how researchers results and conclusions varied is a previously underappreciated explanation for why many scientific hypotheses remain contested. These results call for greater epistemic humility and clarity in reporting scientific findings.

4MOST : Project overview and information for the First Call for Proposals

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Visible and Infrared Survey Telescope for Astronomy (VISTA) at Paranal. Its key specifications are: a large field of view (FoV) of 4.2 square degrees and a high multiplex capability, with 1624 fibres feeding two low-resolution spectrographs (R = λ/Δλ ~ 6500), and 812 fibres transferring light to the high-resolution spectrograph (R ~ 20 000). After a description of the instrument and its expected performance, a short overview is given of its operational scheme and planned 4MOST Consortium science; these aspects are covered in more detail in other articles in this edition of The Messenger. Finally, the processes, schedules, and policies concerning the selection of ESO Community Surveys are presented, commencing with a singular opportunity to submit Letters of Intent for Public Surveys during the first five years of 4MOST operations.

Agaricomycetes

Ingår i: The Mycota. - Berlin : Springer. - 9783642553172 ; , s. 373-429

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Agaricomycetes includes ca. 21,000 described species of mushroom-forming fungi that function as decayers, pathogens, and mutualists in both terrestrial and aquatic habitats. The morphological diversity of Agaricomycete fruiting bodies is unparalleled in any other group of fungi, ranging from simple corticioid forms to complex, developmentally integrated forms (e.g., stinkhorns). In recent years, understanding of the phylogenetic relationships and biodiversity of Agaricomycetes has advanced dramatically, through a combination of polymerase chain reaction-based multilocus phylogenetics, phylogenomics, and molecular environmental surveys. Agaricomycetes is strongly supported as a clade and includes several groups formerly regarded as Heterobasidiomycetes, namely the Auriculariales, Sebacinales, and certain Cantharellales (Tulasnellaceae and Ceratobasidiaceae). The Agaricomycetes can be divided into 20 mutually exclusive clades that have been treated as orders. This chapter presents an overview of the phylogenetic diversity of Agaricomycetes, emphasizing recent molecular phylogenetic studies.

Local recurrence of deep-seated, high-grade, soft tissue sarcoma : 459 Patients from the Scandinavian Sarcoma Group Register
- 2001

Ingår i: Acta Orthopaedica Scandinavica. - : Medical Journals Sweden AB. - 0001-6470. ; 72:2, s. 160-166

Tidskriftsartikel (refereegranskat)abstract
- This study was based on 459 adult patients with deep, high-grade, soft tissue sarcoma of extremities or trunk wall reported to the Scandinavian Sarcoma Group Register (1986-1993). All patients had their definitive surgery for primary tumor at a sarcoma center. The median follow-up was 7.5 (3-12) years. 204 patients are still alive. 68 patients had amputations and 391 underwent limb-sparing surgery. Among 183 patients with intralesional or marginal margins after limb-sparing surgery, 65% had postoperative radiotherapy and 9% of the 198 patients with wide margins. The local recurrence rate after limb-sparing surgery was 26%. The rate with an intralesional or marginal margin was 39% without postoperative radiotherapy versus 24% when radiotherapy was given. It was 25% after a wide margin, and no recurrences were noted among the 10 patients with a compartmental surgical margin. Among patients with a wide margin, a subset fulfilling criteria for a myectomy was defined. The local recurrence rate was 26% among these 62 and there was no advantage of myectomy over other wide margins. More radical surgical margins would improve the local recurrence rate, but this can hardly be achieved in center-operated patients without increasing the amputation rate. Instead, increased use of radiotherapy in all patients with inadequate margins, and to a larger extent in those with wide margins will improve local control.
