- Contaminants in the soil may threaten soil functions (SFs) and, in turn, hinder the delivery of ecosystem services (ES). A framework for ecological risk assessments (ERAs) within the APPLICERA - APPLICable site-specific Environmental Risk Assessment research project promotes assessments that consider other soil quality parameters than only contaminant concentrations. The developed framework is: (i) able to differentiate the effects of contamination on SFs from the effects of other soil qualities essential for soil biota; and (ii) provides a robust basis for improved soil quality management in remediation projects. This study evaluates the socio-economic consequences of remediation alternatives stemming from a Tier 1 ERA that focusses on total contaminant concentrations and soil quality standards and a detailed, site-specific Tier 3 Triad approach that is based on the APPLICERA framework. The present study demonstrates how Tier 1 and Tier 3 ERAs differ in terms of the socio-economic consequences of their remediation actions, as well as presents a novel method for the semi-quantitative assessment of on-site ES. Although the presented Tier 3 ERA is more expensive and time-consuming than the more traditional Tier 1 ERA approach, it has the potential to lower the costs of remediation actions, decrease greenhouse gas emissions, reduce other environmental impacts, and minimise socio-economic losses. Furthermore, the remediation actions stemming from the Tier 3 ERA were predicted to exert far less negative ES effects than the actions proposed based on the results of the Tier 1 ERA.

Uppdaterad och utökad livscykelanalys av svensk grisproduktion
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Förbättrade produktionsresultat inom svensk grisproduktion, användning av biproduk-ter och djurhälsans betydelse har analyserats i en livscykelanalys. Klimatavtrycket för kött från en svensk medelgris är 2,54 kg koldioxidekvivalenter/kg slaktvikt, vilket är bland de lägsta jämfört med tillgängliga internationella studier. Produktionen av foder står för 54 % av klimatavtrycket och hanteringen av stallgödsel för 36 %. Av foderstaten till den svenska integrerade medelslaktgrisen utgjorde biprodukter 10 % och soja 4 %. Baserat på antalet dagars förlängd uppfödningstid för sjuka grisar, visar vi att 3,4 % av klimatavtrycket beror på ökad foderförbrukning orsakad av fyra utvalda sjukdomar i svenska grisbesättningar. Produktionshöjande åtgärder såsom exempelvis friska grisar och hög fodereffektivitet, övergång till förnybara bränslen inom såväl odling av foder som inom grisuppfödning är viktiga åtgärder för att minska klimatavtrycket givet att det inte påverkar andra miljöaspekter, djurhälsa eller djurvälfärd negativt. En central aspekt är fortsatt utveckling mot välbalanserade foderstater med val av foderråvaror med lågt klimatavtryck, användning av biprodukter och inhemska fodergrödor odlade på ett hållbart sätt.

- Background:The delay between onset of macroscopic haematuria and diagnosis of bladder cancer is often long.Methods:We evaluated timely diagnosis and health-care costs for patients with macroscopic haematuria given fast-track access to diagnostics. During a 15-month period, a telephone hotline for fast-track diagnostics was provided in nine Swedish municipalities for patients aged ⩾50 years with macroscopic haematuria. The control group comprised 101 patients diagnosed with bladder cancer in the same catchment area with macroscopic haematuria who underwent regular diagnostic process.Results:In all 275 patients who called ‘the Red Phone’ hotline were investigated, and 47 of them (17%) were diagnosed with cancer and 36 of those had bladder cancer. Median time from patient-reported haematuria to diagnosis was 29 (interquartile range (IQR) 14−104) days and 50 (IQR 27−165) days in the intervention and the control group, respectively (P=0.03). The median health-care costs were lower in the intervention group (655 (IQR 655−655) EUR) than in the control group (767 (IQR 490−1096) EUR) (P=0.002).Conclusions:Direct access to urologic expertise and fast-track diagnostics is motivated for patients with macroscopic haematuria to reduce diagnostic intervals and lower health-care expenditures.British Journal of Cancer advance online publication, 25 August 2016; doi:10.1038/bjc.2016.265 www.bjcancer.com.

- Background: The use of analgesic antipyretics (ANAP) in children have long been a matter of controversy. Data on their practical use on an individual level has, however, been scarce. There are indications of possible effects on glucose homeostasis and immune function related to the use of ANAP. The aim of this study was to analyze patterns of analgesic antipyretic use across the clinical centers of The Environmental Determinants of Diabetes in the Young (TEDDY) prospective cohort study and test if ANAP use was a risk factor for islet autoimmunity. Methods: Data were collected for 8542 children in the first 2.5 years of life. Incidence was analyzed using logistic regression with country and first child status as independent variables. Holm's procedure was used to adjust for multiplicity of intercountry comparisons. Time to autoantibody seroconversion was analyzed using a Cox proportional hazards model with cumulative analgesic use as primary time dependent covariate of interest. For each categorization, a generalized estimating equation (GEE) approach was used. Results: Higher prevalence of ANAP use was found in the U.S. (95.7%) and Sweden (94.8%) compared to Finland (78.1%) and Germany (80.2%). First-born children were more commonly given acetaminophen (OR 1.26; 95% CI 1.07, 1.49; p = 0.007) but less commonly Non-Steroidal Anti-inflammatory Drugs (NSAID) (OR 0.86; 95% CI 0.78, 0.95; p = 0.002). Acetaminophen and NSAID use in the absence of fever and infection was more prevalent in the U.S. (40.4%; 26.3% of doses) compared to Sweden, Finland and Germany (p < 0.001). Acetaminophen or NSAID use before age 2.5 years did not predict development of islet autoimmunity by age 6 years (HR 1.02, 95% CI 0.99-1.09; p = 0.27). In a sub-analysis, acetaminophen use in children with fever weakly predicted development of islet autoimmunity by age 3 years (HR 1.05; 95% CI 1.01-1.09; p = 0.024). Conclusions: ANAP use in young children is not a risk factor for seroconversion by age 6 years. Use of ANAP is widespread in young children, and significantly higher in the U.S. compared to other study sites, where use is common also in absence of fever and infection.

Forskningsöversikt (övrigt vetenskapligt/konstnärligt)abstract
- Utvecklingen av diagnostiska egentest att användas av patienterna själva är både självklar och nyttig. Det förutsätter emellertid att testen håller en god kvalitet och hög diagnostisk sensitivitet. Så är inte alltid fallet, vilket framgår av det i artikeln redovisade screeningtestet för upptäckt av celiaki.

- Celiac disease (CeD) is a disease more prevalent and multisymptomatic than was earlier recognized. Whereas prompt initiation of gluten-free diet (GFD) is beneficial in relieving the symptoms, an accurate CeD diagnosis is necessary also to avoid years of restricted diet on uncertain grounds. We propose a new diagnostic method, based on elution of deposited antibodies against transglutaminase (anti-tTG) from duodenal biopsies in patients with symptoms and screening serology analyses suggestive of CeD. The eluates were analyzed in a Phadia 250 fluoroimmunoassay, demonstrating elevated concentrations of anti-tTG in CeD patients, corresponding to serology and histopathology findings. In one case histology was inconclusive, displaying only unspecific inflammation, but eluted anti-tTG was positive. This patient has clinically improved following GFD. We conclude that our novel method represents a new tool in the diagnostic work up in CeD. The detection of deposited anti-tTG at the site of inflammation appears to provide a high sensitivity and specificity using a technique that is quick, simple and reliable. Further studies are needed for optimization and elucidation of suitable applications for this elution method.
