- BackgroundLittle knowledge is available on implant treatment in large effectiveness studies in routine practice. PurposeTo report retro-prospective data on prevalence of peri-implantitis surgery and late implant failures in a large number of routine patients at 1 referral clinic. Materials and methodsAltogether 9582 implants with an anodized surface (Nobel Biocare AB) were consecutively placed between 2003 and 2011 and followed-up to end of 2015. All peri-implantitis operations and late implant failures were consecutively identified. A logistic multivariate data analysis was performed to identify association between the complications and different clinical factors. Furthermore, data on prevalence on risk for inflammation and bone loss at implants (peri-implantitis) and surgery related to peri-implantitis was collected for another reference group of about 10000 implant patients during 3 consecutive years (2013-2015). ResultsCumulative survival rates for implant operations without peri-implantitis surgery or implant failures were calculated to 96.4% (95% CI: 97.3-95.4) and 95.0% (95% CI: 96.0-94.1) after 10 years, respectively. Risk for peri-implantitis surgery showed a significant association (P<.05) to number of placed implants (hazard ratio [HR] 1.40; 95% CI: 1.24-1.59). Three factors showed significant association to risk for late implant failures, where treatment in lower jaw had the highest risk; HR 2.03. Overall implant failures were associated to 4 significant factors where surgeon (HR 2.50) showed highest impact on risk. Numbers of implants and bone resorption at surgery were the 2 significant factors that were consistent for all the time periods of failures during follow-up (early/late/total). On an average 7.4% of examined patients in the reference group were denoted with highest risk group (peri-implantitis) of which on an average 12.7% of these patients had surgery related to peri-implantitis. ConclusionsThe dentist involved in the surgical and prosthetic rehabilitation of the implant patients, number of implants and degree of bone resorption seem to have most impact on overall implant complications and failures in the present patient group.

- The 2019 International Conference on Software and System Processes (ICSSP 2019) was held in conjunction with the 41st International Conference on Software Engineering (ICSE 2019) in Montreal, Canada, May 25-26, 2019. ICSSP is a leading international forum for research on software and systems processesthe 2019 conference extended a sequence of predecessor conferences and workshops stretching back more than a decade. Although ICSSP has often been associated with ICSE and "in cooperation" with ACM, 2019 was the rst year that ICSSP was operated under a full co-located event agreement with ICSE and was fully sponsored by ACM and IEEE. ICSSP 2019 was organized, as usual, by the International Software and Systems Process Association.

Konferensbidrag (refereegranskat)abstract
- Collective Awareness Platforms (CAP) have been promoted as an enabler of social innovation. A CAP supports the collection of data (quantitative and qualitative, and using all the technical possibilities that are rapidly becoming available, e.g. sensors), the integration of the data, and the presentation of results to the community in order to adapt their behavior or develop new behavior patterns. Typically, a CAP has many stakeholders. To support the development and maintenance of CAPs, we propose the notion of META-CAP, a platform that allows participants to reflect on the CAP from a value and collaboration perspective. The META-CAP architecture described in this paper is evaluated from the perspective of socio-technical design.
