  • Global negative vegetation feedback to climate warming responses of leaf litter decomposition rates in cold biomes
  • 2007

    • Whether climate change will turn cold biomes from large long-term carbon sinks into sources is hotly debated because of the great potential for ecosystem-mediated feedbacks to global climate. Critical are the direction, magnitude and generality of climate responses of plant litter decomposition. Here, we present the first quantitative analysis of the major climate-change-related drivers of litter decomposition rates in cold northern biomes worldwide.Leaf litters collected from the predominant species in 33 global change manipulation experiments in circum-arctic-alpine ecosystems were incubated simultaneously in two contrasting arctic life zones. We demonstrate that longer-term, large-scale changes to leaf litter decomposition will be driven primarily by both direct warming effects and concomitant shifts in plant growth form composition, with a much smaller role for changes in litter quality within species. Specifically, the ongoing warming-induced expansion of shrubs with recalcitrant leaf litter across cold biomes would constitute a negative feedback to global warming. Depending on the strength of other (previously reported) positive feedbacks of shrub expansion on soil carbon turnover, this may partly counteract direct warming enhancement of litter decomposition.

  • Weight increase in patients with dementia, and alteration in meal routines and meal environment after integrity promoting care.
  • 2007

    • Aims. To follow weight changes in patients with moderate and severe dementia and analyse how these changes related to biological and psychological parameters after staff education and support in integrity promoting care. A further aim was to describe meal environment and routines relative to the intervention.Background. Weight loss in patients with dementia and in particular Alzheimer's disease is common. The aetiology appears multifactorial with the meal environment and a decreased independence while eating among the factors.Method. Over a three-month intervention period, an integrity-promoting care training programme was conducted with the staff of a long-term ward. Alzheimer's disease patients, 18 from an intervention ward and 15 from a control ward were included and possible effects were evaluated. Weighing was conducted at the start and after completion of the intervention. Weight changes were analysed in relation to psychological and biochemical parameters. In addition, the staff wrote diaries about, for example changes made in the environment and in their work.Results. The most prominent difference observed was weight increases in 13 of 18 patients compared with two of 15 patients in the control ward. No weight changes were related to the type of dementia. The individual weight changes correlated significantly to changes in the intellectual functions. Relationships between weight change, increased motor function and increased appetite were non-significant. There was no significant relationship between weight changes and changes in biochemical parameters. According to the staff, increased contact with the patients and a more pleasant atmosphere resulted when the meal environment and routines were changed.Relevance to clinical practice. Weight gain in patients with moderate and severe dementia was achieved by adjusting the meal environment to the individual's needs. Staff education was profitable, as increased competence seemed to promote individually adapted feeding situations. Ensuring good meal situations need to be given high priority.

  • A stable and efficient hybrid scheme for viscous problems in complex geometries
  • 2007
  • record:In_t: Journal of Computational Physics. - Uppsala : Elsevier BV. - 0021-9991 .- 1090-2716. ; 226:2, s. 1291-1309

    • In this paper, we present a stable hybrid scheme for viscous problems. The hybrid method combines the unstructured finite volume method with high-order finite difference methods on complex geometries. The coupling procedure between the two numerical methods is based on energy estimates and stable interface conditions are constructed. Numerical calculations show that the hybrid method is efficient and accurate.

  • Donepezil in Alzheimer's disease : What to expect after 3 years of treatment in a routine clinical setting
  • 2007
  • record:In_t: Dementia and Geriatric Cognitive Disorders. - Basel : S. Karger AG. - 1420-8008 .- 1421-9824. ; 23:3, s. 150-160

    • Background/Aims: Clinical short-term trails have shown positive effects of donepezil treatment in patients with Alzheimer's disease. The outcome of continuous long-term treatment in the routine clinical settings remains to be investigated. Methods: The Swedish Alzheimer Treatment Study (SATS) is a descriptive, prospective, longitudinal, multicentre study. Four hundred and thirty-five outpatients with the clinical diagnosis of Alzheimer's disease, received treatment with donepezil. Patients were assessed with Mini-Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), global rating (CIBIC) and Instrumental Activities of Daily Living (IADL) at baseline and every 6 months for a total period of 3 years. Results: The mean MMSE change from baseline was positive for more than 6 months and in subgroups of patients for 12 months. After 3 years of treatment the mean change from baseline in MMSE-score was 3.8 points (95% CI, 3.0-4.7) and the ADAS-cog rise was 8.2 points (95% CI, 6.4-10.1). This is better than expected in untreated historical cohorts, and better than the ADAS-cog rise calculated by the Stern equation (15.6 points, 95% CI, 14.5-16.6). After 3 years with 38% of the patients remaining, 30% of the them were unchanged or improved in the global assessment. Conclusion: Three-year donepezil treatment showed a positive global and cognitive outcome in the routine clinical setting. Copyright © 2007 S. Karger AG.

  • Medical problems in adolescents with myelomeningocele (MMC): an inventory of the Swedish MMC population born during 1986-1989
  • 2007
  • record:In_t: Acta Paediatr. - : Wiley. - 0803-5253 .- 1651-2227. ; 96:3, s. 446-9
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • AIM: To describe the prevalence of myelomeningocele (MMC) and the medical needs of adolescents, 15-18 years, with MMC in Sweden, at a time when they are on the threshold of adulthood, leaving paediatrics. METHODS: In a retrospective study, we identified all adolescents with MMC, born during 1986-1989 and living in Sweden on July 1, 2004. An inventory was agreed upon with questions concerning their medical problems and need for medical care. RESULTS: There were 175 persons 15-18 years of age, born with MMC or lipoMMC (prevalence 3.8 per 10,000). Hydrocephalus was seen in 86%, 31% had been operated because of tethered cord syndrome, and 6% for Chiari malformation symptoms. The majority had motor impairments. Clean intermittent catheterisation for bladder emptying was used by 85%, and 59% used enemas on a regular basis because of the neurogenic bowel dysfunction. Renal dysfunction was seen in 1.7% of the adolescents. CONCLUSION: Lifelong follow-up by many specialists, among others neurologists and neurosurgeons, urotherapists and urologists, orthopaedic surgeons and orthotists, is necessary for individuals with MMC. The complex medical situation, often in combination with cognitive difficulties, makes it necessary to coordinate medical services for this increasing group of adults with multiple impairments.

  • The Swedish rectal cancer registry.
  • 2007
  • record:In_t: The British journal of surgery. - : Oxford University Press (OUP). - 1365-2168 .- 0007-1323. ; 94:10, s. 1285-92
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • BACKGROUND: An audit of all patients with rectal cancer in Sweden was launched in 1995. This is the first report from the Swedish Rectal Cancer Registry (SRCR). METHODS: Between 1995 and 2003, 13 434 patients treated for adenocarcinoma of the rectum were registered with the SRCR; there were approximately 1500 new patients annually. RESULTS: Approximately half had an anterior resection, a quarter an abdominoperineal resection and 15 per cent a Hartmann's procedure. The median 30-day postoperative mortality rate was 2.4 per cent and the overall postoperative morbidity rate was 35.0 per cent. The 5-year cancer-specific survival rate was 62.3 per cent. The 5-year relative survival rate was 70.1 per cent after anterior resection, 59.8 per cent after abdominoperineal resection and 39.8 per cent after a Hartmann's procedure. The crude 5-year local recurrence rate was 9.5 per cent overall, 6.1 per cent after preoperative radiotherapy and 11.4 per cent after surgery alone. For 3868 patients who had a locally curative procedure the local recurrence rate was 7.4 per cent overall, 5.9 per cent for those who had radiotherapy and 10.2 per cent for those who did not. The local recurrence rate was 2.9 per cent (28 of 968) for stage I disease, 7.9 per cent (112 of 1418) for stage II, 13.9 per cent (188 of 1357) for stage III and 8.5 per cent (45 of 532) for stage IV. CONCLUSION: These good population-based results are due, in part, to the nationwide prospective quality assurance registration.

  • Histopathological risk factors for ipsilateral breast events after breast conserving treatment for ductal carcinoma in situ of the breast--results from the Swedish randomised trial.
  • 2007
  • record:In_t: European journal of cancer (Oxford, England : 1990). - : Elsevier BV. - 0959-8049 .- 1879-0852. ; 43:2, s. 291-8
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • AIM: The primary aims were to study risk factors for an ipsilateral breast event (IBE) after sector resection for ductal carcinoma in situ of the breast (DCIS) in a trial comparing adjuvant radiotherapy to no therapy and to assess predictive factors for response to radiotherapy. Secondary aims were to analyse reproducibility of the histopathological evaluation and to estimate correctness of diagnosis in the trial. SETTING: A randomised trial in Sweden (the SweDCIS trial), including 1046 women with a median of 5.2 years of follow-up in a population, offered routine mammographic screening. METHODS: A case-cohort design with a total of 161 cases of IBE (42 of those being members of the subcohort) and 284 sampled for the sub-cohort. Ninety five percent of the participants' slides could be retrieved and were re-evaluated by three experienced pathologists. RESULTS: Low nuclear grade (NG 1-2) and absence of necrosis halves the risk of IBE in both irradiated and non-irradiated patients. Lesion size, margins of excision and age at diagnosis did not modify these associations. The presence of necrosis modified the effect of radiotherapy: relative risk was 0.40 with necrosis present and 0.07 with necrosis absent (p-value for interaction 0.068). In all subsets of prognostic factors, radiotherapy conferred a substantial benefit. The risk factors for in situ and invasive IBE were similar. The agreement between pathologists was moderate (kappa=0.486). Correctness of diagnosis in the subcohort of SweDCIS was 84.8%. CONCLUSION: Although nuclear grade and necrosis carry prognostic information, we could not define a group with very low risk after sector resection alone. Radiotherapy has a protective effect in all substrata of risk factors studied. The interaction between the presence of necrosis and radiotherapy is a clinically and biologically relevant research area.

  • SUMO4 M55V polymorphism affects susceptibility to type I diabetes in HLA DR3- and DR4-positive Swedish patients
  • 2007
  • record:In_t: Genes Immun. - : Springer Science and Business Media LLC. - 1466-4879 .- 1476-5470. ; 8:6, s. 518-21
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • SUMO4 M55V, located in IDDM5, has been a focus for debate because of its association to type I diabetes (TIDM) in Asians but not in Caucasians. The current study aims to test the significance of M55V association to TIDM in a large cohort of Swedish Caucasians, and to test whether M55V is associated in those carrying human leukocyte antigen (HLA) class II molecules. A total of 673 TIDM patients and 535 age- and sex-matched healthy controls were included in the study. PCR-RFLP was performed to identify the genotype and allele variations. Our data suggest that SUMO4 M55V is not associated with susceptibility to TIDM by itself. When we stratified our patients and controls based on heterozygosity for HLA-DR3/DR4 and SUMO4 genotypes, we found that presence of SUMO4 GG increased further the relative risk conferred by HLA-DR3/DR4 to TIDM, whereas SUMO4 AA decreased the risk. From the current study, we conclude that SUMO4 M55V is associated with TIDM in association with high-risk HLA-DR3 and DR4, but not by itself.
