- The aim of the study was to investigate the feasibility of mobilizing Philadelphia chromosome negative (Ph-) blood stem cells (BSC) with intensive chemotherapy and lenograstim (G-CSF) in patients with CML in first chronic phase (CP1). During 1994-1999 12 centers included 37 patients <56 years. All patients received 6 months' IFN, stopping at median 36 (1-290) days prior to the mobilization chemotherapy. All received one cycle of daunorubicin 50 mg/m2 and 1 hour infusion on days 1-3, and cytarabine (ara-C) 200 mg/m2 24 hours' i.v. infusion on days 1-7 (DA) followed by G-CSF 526 microg s.c. once daily from day 8 after the start of chemotherapy. Leukaphereses were initiated when the number of CD 34+ cells was >5/microl blood. Patients mobilizing poorly could receive a 4-day cycle of chemotherapy with mitoxantrone 12 mg/m2/day and 1 hour i.v infusion, etoposide 100 mg/m2/day and 1 hour i.v. infusion and ara-C 1 g/m2/twice a day with 2 hours' i.v infusion (MEA) or a second DA, followed by G-CSF 526 microg s.c once daily from day 8 after the start of chemotherapy. Twenty-seven patients received one cycle of chemotherapy and G-CSF, whereas 10 were mobilized twice. Twenty-three patients (62%) were successfully (MNC >3.5 x 10(8)/kg, CFU-GM >1.0 x 10(4)/kg, CD34+ cells >2.0 x 10(6)/kg and no Ph+ cells in the apheresis product) [n = 16] or partially successfully (as defined above but 1-34% Ph+ cells in the apheresis product) [n = 7] mobilized. There was no mortality during the mobilization procedure. Twenty-one/23 patients subsequently underwent auto-SCT. The time with PMN <0.5 x 10(9)/l was 10 (range 7-49) and with platelets <20 x 10(9)/l was also 10 (2-173) days. There was no transplant related mortality. The estimated 5-year overall survival after auto-SCT was 68% (95% CI 47 - 90%), with a median follow-up time of 5.2 years.We conclude that in a significant proportion of patients with CML in CP 1, intensive chemotherapy combined with G-CSF mobilizes Ph- BSC sufficient for use in auto-SCT.

- Previous reports have shown ambiguous findings regarding the possible associations between ischaemic stroke (IS) and single nucleotide polymorphisms (SNPs) in the phosphodiesterase 4D (PDE4D) gene region. The SNP rs12188950 (or SNP45) has often been studied in this context. We performed a multi-centre study involving a large sample of 2599 IS patients and 2093 control subjects from the south and west regions of Sweden to replicate previous studies regarding IS risk and rs12188950. Subjects from Lund Stroke Register (LSR), Malmo Diet and Cancer Study (MDC) and Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS) were enroled. Subgroups of participants with hypertension and participants <55 years of age, as well as the TOAST subgroups large vessel disease, small vessel disease and cardioembolism, were also assessed. Univariate odds ratios (ORs) and ORs controlling for hypertension, diabetes and current smoking were calculated. We additionally performed a meta-analysis including 10 500 patients and 10 102 control subjects from 17 publications (including the present study). When assessing pooled data from LSR, MDC and SAHLSIS we obtained no association between IS and rs12188950 for all participants (OR=0.93; 95% confidence interval (CI): 0.83-1.05). Significant associations were not found for hypertensive participants or participants with age <55, or when separately evaluating patients from the three different TOAST subgroups. The meta-analysis showed no significant overall estimate (OR=0.96; 95% CI: 0.89-1.04) with significant heterogeneity for random effect (P=0.042). No effect from rs12188950 on IS was found from either our pooled multi-centre data or the performed meta-analysis. We did not find any association between the examined subgroups and rs12188950 either. European Journal of Human Genetics (2012) 20, 783-789; doi: 10.1038/ejhg.2012.4; published online 25 January 2012

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose: The Coronary Artery Disease Genome-Wide Replication and Meta-Analysis Study (CARDIoGRAM) reported 25 single-nucleotide polymorphisms (SNPs) on 15 chromosomes to be associated with coronary artery disease (CAD) risk. Because common vascular risk factors are shared between CAD and ischaemic stroke (IS), these SNPs may also be related to IS overall or one or more of its pathogenetic subtypes. Methods: We performed a candidate gene study comprising 3986 patients with IS and 2459 control subjects. The 25 CAD-associated SNPs reported by CARDIoGRAM were examined by allelic association analysis including logistic regression. Weighted and unweighted genetic risk scores (GRSs) were also compiled and likewise analysed against IS. We furthermore considered the IS main subtypes large-vessel disease (LVD), small-vessel disease and cardioembolic stroke [according to Trial of Org 10172 in Acute Stroke Treatment (TOAST)] separately. Results: SNP rs4977574 on chromosome 9p21.3 was associated with overall IS [odds ratio (OR) = 1.12; 95% confidence interval (CI): 1.04-1.20; P = 0.002] as well as LVD (OR = 1.36; 95% CI: 1.13-1.64; P = 0.001). No other SNP was significantly associated with IS or any of its main subtypes. Analogously, the GRSs did not show any noticeable effect. Conclusions: Besides the previously reported association with SNPs on chromosome 9p21, this study did not detect any significant association between IS and CAD-susceptible genetic variants. Also, GRSs compiled from these variants did not predict IS or any pathogenetic IS subtype, despite a total sample size of 6445 participants.

- In the present study we combined interferon (IFN) and hydroxyurea (HU) treatment, intensive chemotherapy and autologous stem cell transplantation (SCT) in newly diagnosed chronic myelogenous leukemia patients aged below 56 years, not eligible for allogeneic SCT. Patients who had an HLA-identical sibling donor and no contraindication went for an allogeneic SCT (related donor, RD). After diagnosis, patients not allotransplanted received HU and IFN to keep WBC and platelet counts low. After 6 months patients with Ph-positive cells still present in the bone marrow received 1–3 courses of intensive chemotherapy. Those who became Ph-negative after IFN + HU or after 1–3 chemotherapy courses underwent autologous SCT. Some patients with poor cytogenetic response were allotransplanted with an unrelated donor (URD). IFN + HU reduced the percentage of Ph-positive metaphases in 56% of patients, and 1 patient became Ph-negative. After one or two intensive cytotherapies 86 and 88% had a Ph reduction, and 34 and 40% became Ph-negative, respectively. In patients receiving a third intensive chemotherapy 92% achieved a Ph reduction and 8% became Ph-negative. The median survival after auto-SCT (n = 46) was 7.5 years. The chance of remaining Ph-negative for up to 10 years after autologous SCT was around 20%. The overall survival for allo-SCT RD (n = 91) and URD (n = 28) was almost the same, i.e. ≈60% at 10 years. The median survival for all 251 patients registered was 8 years (historical controls 3.5 years). The role of the treatment schedule presented in the imatinib era is discussed.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Socialhögskolans årsbok ger en liten inblick i vad vi gör och vi hoppas att den bidrar till att presentera utsnitt från vår verksamhet på ett trevligt och samlat sätt. Årsboken som är Socialhögskolans tredje uppmärksammar inte bara det som skett på Socialhögskolan under 2018. Den uppmärksammar även att 2018 var året då svensk äldreomsorg fyllde 100 år. Årsbokens gästredaktör Per Gunnar Edebalk inleder därför bokens forskningsavsnitt med att i år skriva om just hundraåringens historia. Det är inledningen på ett avsnitt där flera forskare vid Socialhögskolan bjuder på bidrag som lyfter fram aspekter av äldreomsorg och åldrande.Håkan Jönson och Tove Harnett resonerar om de begrepp som omgärdar äldreomsorgens möten och organisering sett i ett socialt arbetets perspektiv. De två har även skrivit en artikel om huruvida behov ska ses annorlunda mellan grupper bara för att man passerat en viss ålder.Däremellan presenteras en text av Erika Werner som låter oss möta frågor kring en sviken generation, här genom ett möte med Agnes, som hamnade mitt i skarven när pensionssystemet reformerades. Elisabeth Carlstedt presenterar en text om hur äldreomsorgens särskilda boenden arbetar i relation till Socialtjänstlagens direktiv om meningsfullhet och värdighet, och hur svårt det är. Lars Harrysson presenterar därefter ett avsnitt om två forskningsprojekt som han och Erika Werner gjort där fokus har legat dels på pensioner för personer i ekonomiskt utsatta grupper, speciellt med migrantbakgrund, dels om hur tro och äldreomsorg samspelar, eller inte. Äldreomsorgsavsnittet avslutas sedan med en intervju som Patrik Hekkala gjort med Peter Andersson som startade kursen socialt arbete med äldre och med Tove Harnett som tagit över och fortsatt utvecklingsarbetet till dags datum.Årsboken avslutas sedan med fyra texter. En av Amina Abboud, snart färdig socionom, som skriver om sina erfarenheter av och i uppsatsskrivandet. Sedan en där vi får möta Carina Olsson som arbetat hos oss länge, men som faktiskt arbetat vid universitetet i 40 år 2018. Emelie Dahlström, Joakim Grina och Jan Abrahamsson ger sedan en bakgrundsteckning till en hos Socialhögskolan verksam social accelerator, SoPact. Som avrundning finner du sedan lite mer information om vår verksamhet här vid Socialhögskolan.

Konferensbidrag (refereegranskat)abstract
- The use of the virtual work theorem enables one to derive the equations of static equilibrium of fabric, shell and gridshell structures from the compatibility equations linking the rate of deformation of a surface to variations in its velocity. If the structure is treated as a continuum there is no need to consider its micro-structure provided that the grid is fine compared to the overall geometry. Thus we can include fabrics, ribbed shells, corrugated shells and gridshells with a fine grid, such as the Mannheim Multihalle. The equilibrium equations are almost identical to those obtained by assuming that a shell is thin and of uniform thickness, but are more general in their application. Our formulation introduces the concept of geodesic bending moments which are relevant to gridshell structures with continuous laths. The virtual work theorem is more general than the energy theorems, which it in- cludes as a special case. Hence it can be applied to surfaces which admit some form of potential, including minimal surfaces and hanging fabrics. We can then use the calculus of variations for the minimization of a surface integral to define the form of a structure. Many existing formfinding techniques can be rewritten in this way, but we concen- trate on surfaces which minimize the surface integral of the mean curvature subject to a constraint on the enclosed volume, producing a surface of constant Gaussian curvature. This naturally leads to the more general study of conjugate stress and curvature directions, and hence to quadrilateral mesh gridshells with flat cladding panels and no bending moments in the structural members under own weight.

Extending an Industrial Robot Controller-Implementation and Applications of a Fast Open Sensor Interface

Tidskriftsartikel (refereegranskat)abstract
- Many promising robotics research results were obtained during the late 1970s and early 1980s. Some examples include Cartesian force control and advanced motion planning. Now, 20 years and many research projects later, many technologies still have not reached industrial usage. An important question to consider is how this situation can be improved for future deployment of necessary technologies. Today, modern robot control systems used in industry provide highly optimized motion control that works well in a variety of standard applications. To this end, computationally intensive, model-based robot motion control techniques have become standard during the last decade. While the principles employed have been known for many years, deployment in products required affordable computing power, efficientengineering tools, customer needs for productivity/performance, and improved end-user competence in the utilization of performance features. However, applications that are considered nonstandard today motivate a variety of research efforts and system development to package results in a usable form. Actually, robots are not useful for many manufacturing tasks today, in particular those found in small and medium enterprises (SMEs). Reasonsinclude complex configuration, nonintuitive (for the shop floor) programming, and difficulties instructing robots to deal with variations in their environment. The latter challenge includes both task definitions and definition of motion control utilizing external sensors. The key word here is flexibility, and flexible motion control is particularly difficult since the user or system integrator needs to influence the core real-time software functions that are critical for the performance and safe operation of the system. We must find techniques that permit real-time motion controllers to be extended for new, demanding application areas.
