- In gastrointestinal stromal tumors (GISTs), KIT exon 11 deletions are associated with poor prognosis. The aim of this study was to determine the gene expression profiles of GISTs carrying KIT exon 11 deletions and to identify genes associated with poor prognosis. Expression profiling was performed on 9 tumors with KIT exon 11 deletions and 7 without KIT exon 11 mutations using oligonucleotide microarrays. In addition, gene expression profiles for 35 GISTs were analyzed by meta-analysis. Expression of CD133 (prominin-1) protein was examined by tissue microarray (TMA) analysis of 204 GISTs from a population-based study in western Sweden. Survival analysis was performed on patients subjected to R0 resection (n=180) using the Cox proportional hazards model. Gene expression profiling, meta-analysis, and qPCR showed up regulation of CD133 in GISTs carrying KIT exon 11 deletions. Immunohistochemical analysis on TMA confirmed CD133 expression in 28% of all tumors. CD133 positivity was more frequent in gastric GISTs (48%) than in small intestinal GISTs (4%). CD133 positivity was also more frequent in GISTs with KIT exon 11 mutations (41%) than in tumors with mutations in KIT exon 9, PDGFRA, or wild-type tumors (0-17%). Univariate survival analysis showed a significant correlation between the presence of CD133 protein and shorter overall survival (hazard ratio=2.23, P=0.027). Multivariate analysis showed that CD133 provided additional information on patient survival compared to age, sex, NIH risk group and mutational status. CD133 is expressed in a subset of predominantly gastric GISTs with KIT exon 11 mutations and poor prognosis.

Infrasound and low frequency noise from wind turbines
- 2011
-
Ingår i: Environmental Research Letters. - 1748-9326. ; 6:3, s. 035103
-
Tidskriftsartikel (refereegranskat)abstract
- Wind turbines emit low frequency noise (LFN) and large turbines generally generate more LFN than small turbines. The dominant source of LFN is the interaction between incoming turbulence and the blades. Measurements suggest that indoor levels of LFN in dwellings typically are within recommended guideline values, provided that the outdoor level does not exceed corresponding guidelines for facade exposure. Three cross-sectional questionnaire studies show that annoyance from wind turbine noise is related to the immission level, but several explanations other than low frequency noise are probable. A statistically significant association between noise levels and self-reported sleep disturbance was found in two of the three studies. It has been suggested that LFN from wind turbines causes other, and more serious, health problems, but empirical support for these claims is lacking.

- The aim of this study was to investigate the role of 70 Gy salvage radiotherapy (SRT) combined with short-term neoadjuvant hormonal therapy (NHT) in the treatment of recurrent disease after radical prostatectomy (RP), and to consider quality of life (QoL), survival outcomes and impact of co-morbidities on treatment-related rectal-genitourinary toxicity. Electronic records of 184 SRT patients treated consecutively between October 2001 and February 2007 were analyzed. Median age was 64 years (median follow-up 48 months). NHT was given to 165 patients (median 3 months). Pre-RP and pre-SRT PSA, PSA doubling time, Gleason score (GS), seminal vesicle invasion (SVI) and detectable post-SRT PSA were recorded. Any detectable PSA or PSA >0.1 ng/ml + nadir was considered biochemical failure (BcF). The Charlson co-morbidity index was used to correlate co-morbidities and rectal-genitourinary toxicity. Scores from the health-related QoL EORTC QLQ-C30 and PR-25 questionnaires were also evaluated. In 116 (63%) patients, a long-lasting curative effect was indicated by undetectable PSA levels. In univariate analysis, using BcF as an outcome variable, p<0.001 was found for GS, pre-SRT PSA, SVI and detectable post-SRT PSA. Multivariate analysis showed p=0.01 for SVI, p=0.09 for GS, and detectable post-SRT PSA (p=0.01); with metastases as an outcome variable, only SVI was significant (p=0.007). Cancer-specific and overall survival were 99 and 95%, respectively. Although microscopy showed SVI or GS 8-10 in the prostatectomy specimens 17/40 (43%) and 13/29 (45%), respectively, of patients still showed undetectable PSA at long-term follow-up (median 55 months) after SRT. Likewise, 11/31 (36%) patients with pre-SRT PSA >1.0 ng/ml and 80/134 (60%) patients with PSA doubling time (PSADT) <10 still showed undetectable PSA after 50 months. Slightly elevated acute and late rectal-genitourinary grade 3-4 toxicity was observed. No association with co-morbidity/toxicity was found. EORTC QLQ-C30 scores were similar to or slightly better than reference values. SRT with 70 Gy combined with 3-month NHT results in long-term undetectable PSA in >50% of patients with recurrence after RP with acceptable rectal-genitourinary toxicity and without negatively affecting long-term QoL. Non-metastatic patients should not be disqualified from receiving SRT although presenting with poor prognostic factors at surgery.

Etnologin och Medicinen
- 2011

Samlingsverk (redaktörskap) (övrigt vetenskapligt)abstract
- I detta nummer ges en rad exempel där det påvisas att föreställningar, normer och värderingar spelar en avgörande roll i medicinsk praktik. Allt ifrån barnhälsovårdens fyraårskontroller till habiliteringsprocesser för handikappade. I en framåtblickande artikel analyseras problematiken om friskt och sjukt utifrån kartläggning av genetiska markörer. Om den genetiska kartläggningen utsäger att någon med stor sannolikhet kommer att bli sjuk, men kanske 20 år senare. Hur skall vi förhålla oss till detta? I takt med mikroteknologins utveckling kommer allt fler dilemman av detta slag att prägla vården och preventionens vardag. Etnologin kan ge en större förståelse för kulturella processer som finns inom olika medicinska praktikformer, vilket illustreras genom en rad empiriska ingångar i numret.

Ingår i: Contraception. - 0010-7824. ; 74:6, s. 471-475
-
Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: One of the targets of national health programs is to prevent unintended pregnancies, especially among teenagers. It is well established that these often lead to abortion. Preventive programs aimed at decreasing abortion rates should identify target groups at risk for unintended pregnancies.PURPOSE: This study was conducted to determine whether young mothers under 20 years of age constitute a group at risk for new unintended pregnancies.METHODS: A retrospective cohort study comprising teenagers giving birth to their first child from 1996 to 2000 was performed at Orebro University Hospital, Sweden. Data were collected from antenatal and medical records with particular regard to compliance with the postpartum visit and to whether a contraceptive method was prescribed. Information concerning repeat pregnancies during the 12 months after delivery was obtained.RESULTS: A total of 250 deliveries were recorded; 70% of the mothers attended the postpartum visit, and 71% received contraceptive prescriptions. At the 12-month follow-up, 56 (25%) had a new pregnancy, and of those, 20 (36%) had a legal abortion, making the abortion rate fivefold higher than expected in this age group.

Vårdmöten : kulturanalytiska perspektiv på möten inom vården
- 2013
-
Bok (populärvet., debatt m.m.)abstract
- Vårdmötet är inte bara ett möte mellan vårdpersonal och patient. Det är en komplex process där kulturella aspekter, individuella erfarenheter, strukturella förutsättningar och historiska förlopp möts. Den som arbetar inom vården möter tusentals patienter under sitt yrkesliv och många gånger kan mötet ge känslor av förundran, frustration eller till och med irritation. Varför fungerar inte kommunikationen med patienten? I den här boken placerar vi in vårdmötet i en kulturanalytisk förklaringsmodell för att ge svar och verktyg till hur problem kan lösas. I boken utgår vi från empiriska exempel från etnologisk forskning för att diskutera de kulturanalytiska aspekterna av vårdmötet.

Forum för humanistisk-samhällsvetenskaplig hälsoforskning: Forskarkonferens kring temat Program och praktik
- 2011
-
Proceedings (redaktörskap) (refereegranskat)abstract
- Med temat program och praktik vill vi särskilt uppmana forskare att reflektera över vad som sägs och vad som görs inom hälso-, medicin- och sjukdomsrelaterade verksamheter, såväl i nutid som i det förflutna. Med program avses till exempel vårdpolitiska uttalanden och viljeyttringar av olika slag, beskrivningar eller bilder av hur t.ex. vård och omhändertagande bör vara beskaffad, läroböckers beskrivningar av önskvärda metoder, vårdformer, omhändertaganden, ingrepp etc., eller andra sorters vägledande utsagor, bl.a. i massmedia, som anger hur något bör vara beskaffat, ska utföras eller på annat sätt riktas mot en önskvärd omsättning i handling. Med praktik menas t.ex. handlingar, handgrepp och genomförande, tysta eller fotade i något slags program. Här ingår också upplevda och beskrivna relationer mellan t.ex. vårdtagare, klient eller kund och olika vårdgivare eller producenter av vård, behandling och omhändertagande eller andra aktiviteter, rum eller materiella alt. immateriella produkter inom medicin- och hälsofältet. Konferensen vill gärna att deltagarna reflekterar över dessa två begrepp, vart och ett eller i relation till varandra i empiriskt, metodologiskt, källkritiskt eller annat avseende. Konferensen välkomnar också bidrag om de epistemologiska, etiska och representationsteoretiska perspektiv och paradigm som ligger bakom, uttrycks genom eller utesluts från sådana program och praktiker som angivits ovan.
