Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- När Svenska kyrkan, den gamla lutherska statliga institutionen för tro och tillhörighet, ges ny inramning i ett välfärdssamhälle som förändras – förändras då även bilden av kyrkans sociala ansvarstagande?I detta kapitel är ambitionen att beskriva Svenska kyrkans roll i förhållande först till ”välfärdsstaten” och sedan till den välfärdsmix eller den ”välfärdspluralism” som präglar förhållandena idag. För Svenska kyrkans del sammanfaller denna förändring med avregleringen av statskyrkan, det vill säga att genom den nya rollen – och juridiska formen trossamfund – utgöra en del av en annan samhällssektor, det civila samhället.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Syftet med det här kapitlet är att belysa grundläggande villkor för organiseringen av diakonala insatser i Svenska kyrkans församlingar. Vi kommer i första hand fokusera på sådana villkor som rör verksamheten i sig men teologiska förutsättningar berörs också. Vi kommer att konstatera att det i stort saknas riktlinjer för organiseringen av församlingarnas diakoni. Arbetets organisering skiljer sig mycket från församling till församling – i sina olika strukturella och traditionsburna sammanhang – och det finns olika uppfattningar om församlingsdiakonins teologiska grund. Vidare ligger i arbetets natur en hög grad av flexibilitet och hänsynstagande till enskilda förhållanden. Hur hanterar församlingarna det som vi här kommer att beskriva som ett ”församlingsdiakonins frirum”? Den organisatoriska bakgrunden, både teoretiskt, historiskt och så som den framstår i kyrkoordningen, tecknas. Exempel på olika diakonala insatser presenteras i syfte att reflektera kring deras villkor och kvaliteter. Kapitlet lyfter också fram ett par nyckelaktörer. Avslutningsvis lyfts några tendenser rörande organiseringen av församlingsdiakonalt arbete.

- Background/purpose: Bio-electrical impedance spectra of skin cancer and other lesions can be assessed using both regular non-invasive probes and a novel type of microinvasive electrode system with a surface furnished with tiny spikes that penetrate stratum corneum. The aim of the study was to compare the accuracy of detection for various types of skin cancer using impedance spectra measured with these two different electrode systems in an objective way without optimising the power of discrimination. Methods: Impedance spectra of 99 benign nevi, 28 basal cell carcinomas (BCC), and 13 malignant melanomas (MM) were measured using the two electrode systems. Classification of the lesions was made using Fisher's linear discriminant, and the sensitivities and specificities of the techniques were estimated using cross-validation. Results: The best separation between nevi and BCC was achieved using the regular non-invasive probe (96% sensitivity and 86% specificity), whereas the best separation between nevi and MM was achieved using the microinvasive electrodes (92% sensitivity and 80% specificity). Conclusions: Our results indicate that the choice of electrode system is application dependent.

- Electrical bio-impedance can be used to assess skin cancers and other cutaneous lesions. The aim of this study was to distinguish skin cancer from benign nevi using multifrequency impedance spectra. Electrical impedance spectra of about 100 skin cancers and 511 benign nevi were measured. Impedance of reference skin was measured ipsi-laterally to the lesions. The impedance relation between lesion and reference skin was used to distinguish the cancers from the nevi. It was found that it is possible to separate malignant melanoma from benign nevi with 75% specificity at 100% sensitivity, and to distinguish nonmelanoma skin cancer from benign nevi with 87% specificity at 100% sensitivity. The power of skin cancer detection using electrical impedance is as good as, or better than, conventional visual screening made by general practitioners.

Tidskriftsartikel (refereegranskat)abstract
- Flow cytometric (FCM) DNA analysis yields information on ploidy status and the S-phase fraction (SPF), variables of prognostic importance in breast cancer. The clinical value of the SPF is currently being evaluated in prospective randomized trials. The widespread use of FCM DNA analysis emphasizes the importance of reproducibility (both intra- and interlaboratory). In this study, 67 nuclear suspensions of breast cancer samples were analyzed by 12 laboratories routinely performing FCM DNA analysis in breast cancer. No general guidelines were imposed; each laboratory used its own standard protocols. For DNA ploidy status (diploid vs. non-diploid), agreement was complete for 79% (53/67) of the samples, compared with 64% (43/67) of samples when tetraploidy was considered [i.e., euploid (diploid+tetraploid) vs. aneuploid (the remaining non-diploid)]. For the SPF, pairwise comparison of the results of all 12 laboratories yielded a mean Spearman's rank correlation of 0.78 (range: 0.54-0.93). For those 39 samples being categorized in low or high SPF by all laboratories, all agreed in 14 samples (36%). Similar patterns were obtained with kappa measures, agreement being good for ploidy status (diploid vs. non-diploid; overall kappa = 0.87 and 0.74 for euploid vs. aneuploid), but moderate for the SPF [overall kappa = 0.47 (for low SPF vs. high SPF vs. "no SPF reported")]. Discrepancies were chiefly attributable to differences in the categorization of the S-phase values, rather than in FCM procedures, other critical differences being in the detection and interpretation of near-diploid and small non-diploid cell populations, the definition of tetraploidy, and the choice and execution of the method used for S-phase estimation. Based on the observations of this study, detailed guidelines for FCM analysis and interpretation of data are proposed in the Appendix. Some issues remain, however, e.g., to standardize a method for S-phase calculation and tetraploid definition.

Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- I dagens välfärdspluralism antar idéburna organisationer roller som gemenskapsbyggare, röstbärare och serviceleverantörer. Det socialpolitiska landskapet är under ständig förändring – något som påverkar kyrkan och dess diakonala arbete. I kyrklig diakoni ryms praktik och reflektion, teologisk och socialpolitisk. Hur gestaltas detta? Vilka verksamheter prioriteras, hur organiseras och leds det diakonala arbetet? Hur kan diakoni utvecklas som hela församlingens angelägenhet? Vad är diakonens roll jämte andra anställda och frivilliga medarbetare, i de dagliga verksamheterna och i gudstjänsten? I boken diskuteras hur diakoni med sina bibliska rötter kan förstås i dag, bland annat ur ett genusperspektiv. Mänskliga rättigheter är ett sentida inslag i det diakonala arbetet. I antologins tolv kapitel ges också historiska tillbakablickar både vad gäller välfärdspolitik och syn på fattigdom.

- Objective Bone is constantly exposed to dynamic and static loads, which induce both dynamic and static bone strains. Although numerous studies exist on the effect of dynamic strain on implant stability and bone remodeling, the effect of static strain needs further investigation. Therefore, the effect of two different static bone strain levels on implant stability and bone remodeling at two different implantation times was investigated in a rabbit model. Methods Two different test implants with a diametrical expansion of 0.15 mm (group A) and 0.05 mm (group B) creating initial static bone strains of 0.045 and 0.015, respectively. The implants were inserted in the proximal tibial metaphysis of 24 rabbits to observe the biological response at implant removal. Both groups were compared to control implants (group C), with no diametrical increase. The insertion torque (ITQ) was measured to represent the initial stability and the removal torque (RTQ) was measured to analyze the effect that static strain had on implant stability and bone remodeling after 3 and 13 days of implantation time. Results The ITQ and the RTQ values for test implants were significantly higher for both implantation times compared to control implants. A selection of histology samples was prepared to measure bone to implant contact (BIC). There was a tendency that the BIC values for test implants were higher compared to control implants. Conclusion These findings suggest that increased static bone strain creates higher implant stability at the time of insertion, and this increased stability is maintained throughout the observed period.

On a Constitutive Material Model to Capture Time Dependent Behaviour of Cortical Bone
- 2014

- It is commonly known that cortical bone exhibits viscoelastic-viscoplastic behavior which affects the biomechanical response when an implant is subjected to an external load. In addition, long term effects such as creep, relaxation and remodeling affect the success of the implant over time. Constitutive material models are commonly derived from data obtained in in vitro experiments. However during function, remodeling of bone greatly affects the bone material over time. Hence it is essential to include long term in vivo effects in a constitutive model of bone. This paper proposes a constitutive material model for cortical bone incorporating viscoelasticity, viscoplasticity, creep and remodeling to predict stress-strain at various strain rates as well as the behavior of bone over time in vivo. The rheological model and its parameters explain the behavior of bone subjected to longitudinal loading. By a proper set of model parameters, for a specific cortical bone, the present model can be used for prediction of the behavior of this bone under specific loading conditions. In addition simulation with the proposed model demonstrates excellent agreement to in vitro and in vivo experimental results in the literature.
