Rapport (övrigt vetenskapligt/konstnärligt)abstract
- PIXE-analyser kan utföras med utvecklad analysuppställning med noggrannhet och precision av c:a 10 % och med hög analyskapacitet. Ett dataprogram för evaluering av räntgenspektra presenteras. Inverkan av provtjocklek vid PIXE-analys av inhomogena prov har studerats och korrektioner föreslås. Fluorinnehållet i filterprov har bestämts, samtidigt med PIXE-analys, genom utnyttjande av en kärnfysikalisk reaktion som ger resultat med god noggrannhet och precision. Svetsaerosoler har karakteriserats m.h.a. PIXE, ESCA och TEM/EDAX. En uppställning för insamling av svetsaerosoler under utveckling och hittillsvarande resultat indikerar representativ provinsamling med god reproducerbarhet.

Antithymocyte globulin and cyclosporine A as combination therapy for low-risk non-sideroblastic myelodysplastic syndromes
- 2006
-
Ingår i: Haematologica. - 0390-6078 .- 1592-8721. ; 91:5, s. 667-670

Tidskriftsartikel (refereegranskat)abstract
- The present study evaluated the combination of antithymocyte globulin (ATG) and cyclosporine A (CsA) in patients with low-risk myelodysplastic syndromes. Twenty patients (17 with refractory anemia and 3 with refractory anemia with excess blasts) received treatment with rabbit-ATG plus CsA. The overall response rate was 30% (6/20); three of the six responders had a complete response. The responses lasted 2-58 months, with two patients still being in complete remission at 42 and 58 months. Short-lasting cytogenetic remissions were achieved in two patients. ATG was poorly tolerated in patients over 70 years of age. Four out of 20 patients progressed to acute myeloid leukemia within a year. We conclude that immunosuppressive treatment may be a therapeutic option for selected patients with myelodysplastic syndrome.

Reflective Production in the Final Assembly of Motor Vehicles - An Emerging Swedish Challenge
- 1992
-
Ingår i: International Journal of Operations and Production Management. - 1758-6593 .- 0144-3577. ; 12:7/8, s. 117-133
-
Tidskriftsartikel (refereegranskat)abstract
- Presents some theoretical principles and empirical evidence relating to the new Swedish production systems for final assembly of motor vehicles. Contends that in these production systems it is possible simultaneously to enhance efficiency and quality of working life. Briefly sketches three production forms as they apply to the final assembly of automobiles and discusses the societal environments in which these different forms of production have evolved. It focuses on Volvo Uddevalla plant as one of the main examples so far of a reflective production system for final assembly of automobiles. Amplifies the analysis of different production flow patterns for final assembly and in particular addresses the issue of semi‐parallel mechanistic production flow and parallel organic production flow as alternatives to serial flow on a conventional line assembly. A comment: This publication is authored together with e.g. senior research competencies (1) within vocational learning and training as well as (2) within time-geography with whom Engström have had long time cooperation procedures. But also personal at our department/research group (Mats Johansson) well as our knowledgeable contact person (Bertil Johansson) within Volvo contributed (he has really helped us out for decades and was responsible for the continuous contacts with Volvo in most any matter).

Aerosolsammansättning i ett renluftsområde
- 1979
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Aerosolsammansättningen i ett renluftsområde i Mellansverige (Velen) har studerats under en årscykel. Aerosolpartiklarna har uppdelats efter aerodynamisk storlek i 7 fraktioner. Varje fraktion från 113 provtagningstillfällen har analyserats m a p svavel och tungmetaller m h a partikelinducerad röntgenstrålning s k PIXE-analys. Resultaten påvisar variationer i ämneskoncentrationer mellan enskilda mättillfällen omspännande två storleks ordningar. Årsmedelkoncentrationerna ligger på samma nivå som i rural miljö i Bolivia, Canada, Norge och Schweiz. Jämfört med motsvarande koncentrationer i urban miljö (Köpenhamn m fl storstäder) är tungmetallkoncentrationerna en till två storleksordningar (svavelkoncentrationen endast en faktor tre) lägre i Velen. Inga påtagliga säsongsvariationer kunder spåras varken för antropogent eller naturligt bildade ämnen. Klassificering av mättillfällena efter luftmassans historia kunde förklara mycket av de stora koncentrationsvariationerna. Grundämneskoncentrationerna var mellan en faktor 2 och 10 högre i luftmassor som kom från den europeiska kontinenten eller Storbritannien jämfört med de som kom norrifrån. Lägst var koncentrationerna i luftmassor som kom från Nordatlanten eller Norska Havet. Svavelkoncentrationerna visade störst beroende av luftmassans historia.

Tidskriftsartikel (refereegranskat)abstract
- Unsuccessful cytogenetics (UC) in patients with acute myeloid leukaemia (AML) treated on different SWOG trials was recently reported to be associated with increased age and dismal outcome. To ascertain whether this holds true also in unselected patients with AML, we retrieved all cytogenetic reports in cases from the population-based Swedish AML Registry. Between 1997 and 2006, 1737 patients below 80 yr of age without myelosarcoma or acute promyelocytic leukaemia received intensive treatment. The frequencies of UC and unperformed cytogenetics (UPC) were 2.1% and 20%, respectively. The early death rates differed between the cytogenetic subgroups (P = 0.006) with the highest rates in patients with UC (14%) and UPC (12%) followed by high-risk (HR) AML, intermediate risk (IR) and standard risk (SR) cases successfully karyotyped (8.6%, 5.9%, and 5.8%, respectively). The complete remission rate was lower in UC and UPC and HR compared with the other risk groups (P < 0.001). The overall five-year survival rates were 25% for UC and 22% for UPC, whereas the corresponding frequencies for SR, IR and HR AML patients without UC and UPC were 64%, 31% and 15%, respectively. In conclusion, lack of cytogenetic data translates into a poor prognosis.

Tidskriftsartikel (refereegranskat)abstract
- The Swedish population-based acute myeloid leukemia registry contains data from 3251 patients (excluding acute promyelocytic leukemia) diagnosed between 1997 and 2006. Informative cytogenetic data from 1893 patients were retrospectively added, including 1054 patients aged between 60 and 79 years. Clonal abnormalities were found in 57% of the informative karyotypes. Karyotypic patterns differed by age: t(8; 21), inv(16) and t(11q23) were more common in younger patients, whereas loss of 5q, 7q and 17p, monosomal karyotype (MK) and complex karyotypes were more common in older patients. Loss of 5q, 7q and 17p often occurred together within MK. Patients with greater than= 5 chromosome abnormalities had worse overall survival than those with fewer abnormalities or normal karyotype in all age groups. Loss of 5q, 7q and/or 17p had, in contrast to MK, a further negative impact on survival. Multivariable Cox regression analyses on risk factors in patients less than80 years with cytogenetic abnormalities and intensive treatment revealed that age and performance status had the most significant impact on survival (both Pless than0.001), followed by sex (P = 0.0135) and a karyotype including - 7/del(7q) (P = 0.048).

Tidskriftsartikel (refereegranskat)abstract
- To ascertain the clinical implications of high hyperdiploid (HH; 49-65 chromosomes) and triploid/tetraploid (TT; greater than65 chromosomes) adult acute myeloid leukemia (AML), all such cases were retrieved from the Swedish AML Registry. Of the 3,654 cytogenetically informative cases diagnosed between January 1997 and May 2014, 68 (1.9%) were HH (n=50)/TT (n=18). Patients with HH/TT were older than those with intermediate risk (IR) AML (median 71 years vs. 67 years; P=0.042) and less often had de novo AML (63% vs. 79%; P=0.004); no such differences were observed between HH/TT and complex karyotype (CK) AML. The overall survival (OS) was similar between patients with HH/TT and CK AML (median 0.9 years vs. 0.6 years; P=0.082), whereas OS was significantly longer (median 1.6 years; P=0.028) for IR AML. The OS was shorter for cases with HH than with TT (median 0.6 years vs. 1.4 years; P=0.032) and for HH/TT AMLs with adverse abnormalities (median 0.8 years vs. 1.1 years; P=0.044). In conclusion, HH/TT AML is associated with a poor outcome, but chromosome numbers greater than65 and absence of adverse aberrations seem to translate into a more favorable prognosis. Thus, HH/TT AMLs are clinically heterogeneous and should not automatically be grouped as high risk.Am. J. Hematol. 90:800-805, 2015. (c) 2015 Wiley Periodicals, Inc.

- OBJECTIVES AND METHODS: To ascertain the incidence/clinical implications of isolated autosomal trisomies in adult acute myeloid leukemia (AML), all such cases were retrieved from the Swedish AML Registry.RESULTS: Of the 3179 cytogenetically informative AMLs diagnosed January 1997-May 2015, 246 (7.7%) had isolated trisomies. The frequency increased by age (2.4% at age 18-60 years vs. 23% at >60 years; P<.0001); the median age was 69 years. The five most common were +8 (4.0%), +13 (0.9%), +11 (0.8%), +21 (0.7%), and +4 (0.5%). Age and gender, types of AML and treatment, and complete remission and early death rates did not differ between the single trisomy and the intermediate risk (IR) groups or among cases with isolated gains of chromosomes 4, 8, 11, 13, or 21. The overall survival (OS) was similar in the single trisomy (median 1.6 years) and IR groups (1.7 years; P=.251). The OS differed among the most frequent isolated trisomies; the median OS was 2.5 years for +4, 1.9 years for +21, 1.5 years for +8, 1.1 years for +11, and 0.8 years for +13 (P=.013).CONCLUSION: AML with single trisomies, with the exception of +13, should be grouped as IR.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The aims of this study were to describe and compare quality of life (QOL) before and after designation to a palliative homecare team (PHT) in patients with different cancer diagnoses and to identify pre-designation predictors of post-designation global QOL. We measured patients� QOL one week before designation and 11 days (median time) after with the Assessment of Quality of life at the End of Life (AQEL). Of 163 eligible patient 63 participated without attrition. Patients� QOL improved in the physical, psychological, medical and global areas. Six items significantly improved: hours recumbent during the day (p=.009), nausea (p=.008), anxiety (p=.007), getting hold of staff (p=.000), received care (p=.003) and global QOL (p=.023). Depression/low in mood (r=.55) and meaningfulness (r=.70) associated to global QOL. Furthermore, pain (p=.028) and meaningfulness (p=.028) predicted global QOL. In the existential area, it is important to further explore how meaningfulness is associated to and predicts global QOL.

Caregivers' perceptions about terminally ill family members' quality of life
- 2007
-
Ingår i: European Journal of Cancer Care. - : Hindawi Limited. - 0961-5423 .- 1365-2354. ; 16:4, s. 338-345

Tidskriftsartikel (refereegranskat)abstract
- Caregivers' perceptions on terminally ill family members' quality of life is rarely described. The aim of this study was to describe caregivers' perceptions about terminally ill family members' quality of life when suffering from cancer. Four caregivers participated in repeated focus group, and the data were analysed using qualitative content analysis. The findings were presented through five themes: 'living a normal life', 'being relieved from burdens', 'having a sense of belonging', 'being a symbol of incurable illness' and 'having a sense of dignity'. We found that to manage daily life it was significant to keep up a normal life and participate in social life. One new insight in this study was that caregivers contributed to an extending understanding to the term meaning in which the sense of belonging was fundamental. An obstacle for the sense of belonging was illuminated as the visible signs of incurable illness that stigmatized the ill person, and influenced the dignity. This study highlights the importance of supportive actions from significant others and healthcare professionals for terminally ill family members' quality of life.

The meaning of quality of life: narrations by patients with incurable cancer in palliative home care
- 2008
-
Ingår i: Palliative & Supportive Care. - 1478-9515 .- 1478-9523. ; 6:3, s. 231-238
-
Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: The objective of this qualitative study was to elucidate the meaning of quality of life as narrated by patients with incurable cancer approaching death in palliative home care in Sweden. METHODS: To gain a deeper understanding of what quality of life means for dying patients, data were collected from narrative interviews with eight patients in their homes in 2004-2006. Qualitative content analysis was used to interpret the meaning regarding quality of life. RESULTS: Three main themes were found: being in intense suffering, having breathing space in suffering, and being at home. Living with incurable cancer at the end of life was experienced as living in physical distress as the body became incapacitated by unexpected physical complications. This incapacity had consequences on patients' psychological, social, and existential well-being. As the complication phase abated, the patients experienced that they regained hopefulness and had time to reflect on existential issues. Patients were provided affirmative care at home from family caregivers and the palliative home care team. SIGNIFICANCE OF RESULTS: This study shows that it is feasible to perform individual interviews with patients approaching death and elucidate the meaning of patients' quality of life in palliative home care. Patients oscillate between being in intense suffering and having breathing space in this suffering, which somewhat opposes the traditional picture of a continuous linear deterioration. Being cared for at home by family caregivers and health care professionals provided a sense of independency and security. Being at home safeguards patients' entire life situation and increases quality of life.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This article outlines a numerical study on the benefit of using high-performance and high-strength concrete (HPC/HSC) for fabrication of concrete elements. A comparison is made between the cost of existing beams with normal strength concrete and optimized beams made of HPC/HSC. Background is given concerning the most essential properties of HPC/HSC such as strength, creep, shrinkage, carbonation, and fire resistance. Results indicate that it is necessary to improve the structural configuration of the beams to fit with 16 mm strand to achieve an economical solution. The direct cost reduction after optimization of the section was 15 percent. Other advantages such as approximately 35 percent reduction of the required amount of carbon dioxide to produce cement for the same type of beam, lower cost of transport, and a decreased dead weight of the structure compared with the use of normal strength concrete motivates the use of HPC/HSC for these types of structures.
