- ABSTRACT: BACKGROUND: Today, no objective criteria exist to differentiate between individual primary tumors and intra- or intermammary dissemination respectively, in patients diagnosed with two or more synchronous breast cancers. To elucidate whether these tumors most likely arise through clonal expansion, or whether they represent individual primary tumors is of tumor biological interest and may have clinical implications. In this respect, high resolution genomic profiling may provide a more reliable approach than conventional histopathological and tumor biological factors. METHODS: 32 K tiling microarray-based comparative genomic hybridization (aCGH) was used to explore the genomic similarities among synchronous unilateral and bilateral invasive breast cancer tumor pairs, and was compared with histopathological and tumor biological parameters. RESULTS: Based on global copy number profiles and unsupervised hierarchical clustering, five of ten (p = 1.9 x 10-5) unilateral tumor pairs displayed similar genomic profiles within the pair, while only one of eight bilateral tumor pairs (p = 0.29) displayed pair-wise genomic similarities. DNA index, histological type and presence of vessel invasion correlated with the genomic analyses. CONCLUSION: Synchronous unilateral tumor pairs are often genomically similar, while synchronous bilateral tumors most often represent individual primary tumors. However, two independent unilateral primary tumors can develop synchronously and contralateral tumor spread can occur. The presence of an intraductal component is not informative when establishing the independence of two tumors, while vessel invasion, the presence of which was found in clustering tumor pairs but not in tumor pairs that did not cluster together, supports the clustering outcome. Our data suggest that genomically similar unilateral tumor pairs may represent a more aggressive disease that requires the addition of more severe treatment modalities, and underscores the importance of evaluating the clonality of multiple tumors for optimal patient management. In summary, our findings demonstrate the importance of evaluating the properties of both tumors in order to determine the most optimal patient management.

Konferensbidrag (refereegranskat)abstract
- The Faculty of Sciences at Lund University has developed online courses to enhance physical as well as virtual exchange and promote joint delivery of courses among partner universities. The purpose is to increase the flexibility of studies within joint programmes. As part of the development of a blended mode course we have included an online research tool, “Global Research Gateway”.

- OBJECTIVE: To determine prevalence and intensity of pain after stroke, focusing on patients' perspectives. METHODS: During a one year period, 416 first-ever stroke patients were included in the population based Lund Stroke Register. After 4 and 16 months (median), 297 patients (98% of survivors) were followed up. Worst pain intensity during the previous 48 hours was assessed on a visual analogue scale (VAS), range 0 to 100: a score of 0 to 30 was defined as no or mild pain; 40 to 100 as moderate to severe pain. NIH stroke scale (NIHSS) score and HbA1c were assessed at baseline. At 16 months, screening for depression was done using the geriatric depression scale (GDS-20), and cognition with the mini-mental state examination (MMSE). Predictors of pain were determined by multivariate analyses. RESULTS: Moderate to severe pain was reported by 96 patients (32%) after four months (VAS median=60). Predictors of pain were younger age (p=0.01), female sex (p=0.006), higher NIHSS score (p<0.001), and raised HbA1c (p=0.001) at stroke onset. At 16 months, only 62 patients (21%) had moderate to severe pain, but pain intensity was more severe (median VAS score=70; p<0.016). Higher pain intensity correlated with female sex, worse GDS-20 score, better MMSE score, and raised HbA1c. Pain was persistent in 47%, disturbed sleep in 58%, and required rest for relief in 40% of patients. CONCLUSIONS: Although prevalence of pain after stroke decreased with time, after 16 months 21% had moderate to severe pain. Late pain after stroke was on average more severe, and profoundly affected the patients' wellbeing.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND PURPOSE: Data on the prevalence and indicators of weight loss in population-based groups of stroke survivors are scarce. We aimed to find the predictors and indicators of weight loss >3 kg as a possible marker of malnutrition after stroke. METHODS: We registered weight at baseline, after 4 months, and 1 year later in 305 survivors from a population-based cohort of first-ever stroke patients. Characteristics of the patients were registered at baseline and follow-ups, including glycosylated hemoglobin at baseline and follow-up II, eating difficulties at both follow-ups, and screening for depression at follow-up II. We used univariate and multivariate analyses to find baseline predictors and follow-up indicators related to weight loss >3 kg from baseline. RESULTS: Among the 305 patients, 60% were male, the mean age was 72.5 years, and mean body mass index was 25.8 kg/m(2). The main stroke types were cerebral infarction (89%), intracerebral hemorrhage (7%), and subarachnoid hemorrhage (4%). Weight loss >3 kg was found in 74 (24%) patients (mean, -6.6 kg) after 4 months and in 79 patients (26%; mean, -8.3 kg) 1 year later. Severe stroke and elevated glycosylated hemoglobin levels were baseline predictors of weight loss >3 kg. Indicators associated with short-term weight loss (at follow-up I) were eating difficulties, low prealbumin value, and dependence (Barthel Index), whereas indicators associated with long-term weight loss (follow-up II) were eating difficulties, hemorrhagic stroke, and low prealbumin value. CONCLUSIONS: Weight loss >3 kg after stroke indicates the need for closer observation regarding nutritional status. Monitoring of body weight may be useful, particularly among patients with severe stroke, eating difficulties, low prealbumin values, and impaired glucose metabolism

Bok (övrigt vetenskapligt/konstnärligt)abstract
- Det mesta i den här boken tar sin utgångspunkt i människor med funktionsnedsättningar. Situationer med stora svårigheter behöver en stark prioritering, både för sin egen del och för att det särskilda förr eller senare brukar komma det gemensamma till godo. Boken har två delar. Den första består av tio minst sagt spretiga kapitel som alla visar på att hur svår en situation än är, finns det alltid något man kan göra. Dessa kapitel är nog så innehållsrika men samtidigt lättlästa. De är helt enkelt avsedda att berätta sina historier, rakt upp och ner, varje kapitel för sig. Fullt så lättläst är inte del 2. I den försöker vi visa på teori- och metodbildning som kan underlätta, hålla samman och vidareutveckla. Den delen har också en rikhaltig referenslista för vidare studier.

Tidskriftsartikel (refereegranskat)abstract
- Recent meta-analyses of the methylenetetrahydrofolate reductase gene (MTHFR) have suggested association between two of its functional single gene polymorphisms (SNPs, C677T and A1298C) and schizophrenia. Studies have also suggested association between MTHFR C677T and A1298C variation and bipolar disorder. In a replication attempt the MTHFR C677T and A1298C SNPs were analyzed in three Scandinavian schizophrenia case-control samples. In addition, Norwegian patients with bipolar disorder were investigated. There were no statistically significant allele or genotype case-control differences. The present Scandinavian results do not verify previous associations between the putative functional MTHFR gene polymorphisms and schizophrenia or bipolar disorder. However, when combined with previous studies in meta-analyses there is still evidence for association between the MTHFR C677T polymorphism. and schizophrenia. Additional studies are warranted to shed further light on these relationships. (c) 2007 Wiley-Liss, Inc.
