Where are we now with European forest multi-taxon biodiversity and where can we head to?

The European biodiversity and forest strategies rely on forest sustainable management (SFM) to conserve forest biodiversity. However, current sustainability assessments hardly account for direct biodiversity indicators. We focused on forest multi-taxon biodiversity to: i) gather and map the existing information; ii) identify knowledge and research gaps; iii) discuss its research potential. We established a research network to fit data on species, standing trees, lying deadwood and sampling unit description from 34 local datasets across 3591 sampling units. A total of 8724 species were represented, with the share of common and rare species varying across taxonomic classes: some included many species with several rare ones (e.g., Insecta); others (e.g., Bryopsida) were represented by few common species. Tree-related structural attributes were sampled in a subset of sampling units (2889; 2356; 2309 and 1388 respectively for diameter, height, deadwood and microhabitats). Overall, multi-taxon studies are biased towards mature forests and may underrepresent the species related to other developmental phases. European forest compositional categories were all represented, but beech forests were over-represented as compared to thermophilous and boreal forests. Most sampling units (94%) were referred to a habitat type of conservation concern. Existing information may support European conservation and SFM strategies in: (i) methodological harmonization and coordinated monitoring; (ii) definition and testing of SFM indicators and thresholds; (iii) data-driven assessment of the effects of environmental and management drivers on multi-taxon forest biological and functional diversity, (iv) multi-scale forest monitoring integrating in-situ and remotely sensed information

Iron Behaving Badly: Inappropriate Iron Chelation as a Major Contributor to the Aetiology of Vascular and Other Progressive Inflammatory and Degenerative Diseases

The production of peroxide and superoxide is an inevitable consequence of aerobic metabolism, and while these particular "reactive oxygen species" (ROSs) can exhibit a number of biological effects, they are not of themselves excessively reactive and thus they are not especially damaging at physiological concentrations. However, their reactions with poorly liganded iron species can lead to the catalytic production of the very reactive and dangerous hydroxyl radical, which is exceptionally damaging, and a major cause of chronic inflammation. We review the considerable and wide-ranging evidence for the involvement of this combination of (su)peroxide and poorly liganded iron in a large number of physiological and indeed pathological processes and inflammatory disorders, especially those involving the progressive degradation of cellular and organismal performance. These diseases share a great many similarities and thus might be considered to have a common cause (i.e. iron-catalysed free radical and especially hydroxyl radical generation). The studies reviewed include those focused on a series of cardiovascular, metabolic and neurological diseases, where iron can be found at the sites of plaques and lesions, as well as studies showing the significance of iron to aging and longevity. The effective chelation of iron by natural or synthetic ligands is thus of major physiological (and potentially therapeutic) importance. As systems properties, we need to recognise that physiological observables have multiple molecular causes, and studying them in isolation leads to inconsistent patterns of apparent causality when it is the simultaneous combination of multiple factors that is responsible. This explains, for instance, the decidedly mixed effects of antioxidants that have been observed, etc...Comment: 159 pages, including 9 Figs and 2184 reference

Microsatellite genotyping clarified conspicuous accumulation of Candida parapsilosis at a cardiothoracic surgery intensive care unit.

Contains fulltext : 124291.pdf (publisher's version ) (Open Access)Candida parapsilosis has become a significant cause of invasive fungal infections in seriously ill patients. Nosocomial outbreaks through direct and indirect contact have been described. The aim of this study was the molecular characterization of what appeared to be an ongoing C. parapsilosis outbreak at the cardiothoracic intensive care unit of the University Hospital of Vienna between January 2007 and December 2008. Using two different molecular typing methods-automated repetitive sequence-based PCR (DiversiLab; bioMerieux) and microsatellite genotyping-we investigated the genetic relationship of 99 C. parapsilosis isolates. Eighty-three isolates originated from the cardiothoracic intensive care unit, while 16 isolates were random control isolates from other intensive care units and a different Austrian hospital. The 99 C. parapsilosis isolates analyzed by repetitive-element PCR all showed identical genotypes, suggesting an ongoing outbreak. In contrast, microsatellite genotyping showed a total of 56 different genotypes. Two major genotypes were observed in 10 and 15 isolates, respectively, whereas another 13 genotypes were observed in 2 to 4 isolates each. Forty-one genotypes were observed only once. Closely related genotypes that differed in only a single microsatellite marker were grouped into clonal complexes. When it comes to C. parapsilosis, microsatellite genotyping is a more discriminative method than repetitive-element PCR genotyping to investigate outbreaks.1 november 201

Version 1.1 of the international spinal cord injury skin and thermoregulation function basic data set

Objective: To describe the changes made to the international spinal cord injury (SCI) skin and thermoregulation function basic data set in version 1.1. Setting: International. Methods: An international working group reviewed suggested changes to the international SCI skin and thermoregulation function basic data set version 1.0. These changes were discussed and the agreed changes were made. Subsequently, the recommended adjustments were circulated for review to the International Spinal Cord Society (ISCoS) Executive and Scientific Committees, the American Spinal Injury Association (ASIA) Board, around 40 national and international societies, and to interested individuals who had signed up wishing to have the opportunity to review. In addition, the suggested changes were displayed at the ISCoS and ASIA websites for at least a month for possible comments. Results: The recommendation ` largest diameter, including undermining' is changed to: 'Largest undermining', and a description of how to measure this is inserted. The 'smallest opening diameter' is changed to: 'Width' as the maximum dimension perpendicular to the length axis. In the literature, there is a tendency to replace 'grades' or 'stages' with 'categories'; therefore, the word category' is used instead of 'grade' or 'stage'. Conclusions: Impracticable measurements have been adjusted and new terminology adopted. All are to be found on ISCoS website: http://www.iscos.org.uk/international-sci-skin-and-thermoregulation-function-data-sets

Impact of health problems secondary to SCI one and five years after first inpatient rehabilitation

Study design: This is a multicenter prospective cohort study. Objectives: The objective of this study was to describe and compare the impact of health problems secondary to spinal cord injury (SCI) on functioning at home and on social activities at 1 and 5 years after discharge from first inpatient rehabilitation. Setting: The study was conducted in a Dutch community. Methods: Participants with SCI who use a wheelchair for everyday mobility (N=110) completed a self-report questionnaire as part of a larger cohort study including four items on extra time needed (body care, bladder and bowel regulation, 'organization' and transportation) and impact of 10 health problems on functioning at home and on social activities. The 10 health problems include secondary health conditions (bladder regulation, bowel regulation, decubitus, pain, spasticity, gain in body weight and edema), psychosocial problems (sexuality, having difficulty with being dependent on help from others) and handicap management. Results: Median extra time needed for self-management and transportation was not significantly higher 1 year after discharge (16 (IQR 13.5) h per week) compared with 5 years after discharge (13 (IQR 17) h per week) (P=0.925). Participants reported slightly less impact, comparing the severity sum-score (range 10-50) of the 10 health problems on functioning at home and in social activities, 5 years post discharge (20 and 17, respectively) than 1 year post discharge (21 and 18, respectively; P Conclusions: The impact of health problems after SCI is considerable and hardly diminishes over time. These results emphasize the need for structured long-term care for people with SCI

Secondary health conditions and quality of life in persons living with spinal cord injury for at least ten years

OBJECTIVES: To describe the prevalence of secondary health conditions among persons with long-term spinal cord injury, and the relationship between these secondary health conditions and quality of life. DESIGN: Multicentre, cross-sectional study. SUBJECTS: Individuals (n = 282) with traumatic or non-traumatic spinal cord injury for ≥ 10 years, age at injury 18-35 years, current age 28-65 years, and using a wheelchair. METHODS: Occurrence of 13 secondary health conditions was assessed during a consultation with a rehabilitation physician. Quality of life was measured with the International Spinal Cord Injury Quality of Life Basic Data Set. RESULTS: Median time since injury was 22.0 years. Median number of secondary health conditions was 4. The most prevalent secondary health conditions were: musculoskeletal pain (63.5%), oedema (38.7%), neuropathic pain (34.1%) and urinary tract infections (33.3%). Only oedema showed a significant association with increasing time since injury. Median Total Quality of Life Basic Data Set score was 7. Musculoskeletal pain, pressure ulcers, problematic spasticity and constipation showed an independent association with quality of life in multiple regression analysis, but in general, these associations were weak. CONCLUSION: Secondary health conditions are common among persons with long-term spinal cord injury and the following secondary health conditions were independently associated with lower quality of life: musculoskeletal pain, pressure ulcers, problematic spasticity, and constipation. Minimizing the impact of secondary health conditions should be a priority in the long-term care of persons with spinal cord injury
