Utsättning av djur för jakt och fiske
- 2021
-
Book (pop. science, debate, etc.)abstract
- SLUs vetenskapliga råd för djurskydd har fått i uppdrag av Jordbruksverket att sammanställa aktuell forskning kring utsättning av djur för jakt och fiske samt att belysa eventuella kunskapsluckor på området. Uppdraget omfattar gräsand, rapphöna, fasan och laxfiskar. Bruket att föda upp fåglar och fiskar för utsättning i syfte att gynna jakt och fiske ifrågasätts inte sällan av etiska skäl, men den diskussionen ligger utanför fokus för denna rapport. Utsättning av fågel och fisk är en antropogen verksamhet som, till skillnad från många andra typer av mänsklig påverkan, syftar till att gynna arterna i fråga. Det kan handla om naturvårdsinsatser, att återinföra försvunna arter eller att på andra sätt berika ekosystemet, inte sällan med ökade möjligheter till jakt eller fiske som slutändamål. Ofta förbereds och åtföljs utsättningar av habitatförbättrande åtgärder som inte endast gynnar de utsatta individerna och deras artfränder, utan även har positiva konsekvenser för biologisk mångfald och ekosystemet i stort. I utarbetandet av regelverket knutet till utsättning av fågel och fisk är det viktigt att även beakta de positiva föresatserna och de konsekvenser som verksamheten kan medföra. Annars riskerar man att engagemang och incitament förloras, till men för biologisk mångfald och en rik och levande landsbygd.

- 2024. - 2024
-
Reports (pop. science, debate, etc.)abstract
- Gröna och artrika utemiljöer främjar barns och ungas välbefinnande och kunskap, bådegenom hälsofördelar kopplade till biologisk mångfald och genom att skapa förutsättningarför lek och lärande om natur och miljöfrågor. Skolgården skulle kunna bidra till allt detta,men är idag i hög grad en outnyttjad plats för biologisk mångfald och klimatanpassningav städer. I denna policy brief presenteras huvudsakliga motiv och möjliga åtgärder för attutveckla gröna miljöer och biologisk mångfald på skolgårdar och förskolegårdar.

Hur mjölk i tanken blir kronor på banken : Bondförnuftets rationalitet
- 2024
-
Doctoral thesis (other academic/artistic)abstract
- Lantbrukare har under senare år ofta hörts framföra klagomål om att den administrativa bördan blivit allt tyngre vad gäller rapportering och ansökningar som ska göras till olika myndigheter. Tidigare forskning framställer det som att den administrativa bördan skulle kunna utsträckas till att också gälla redovisning, så som bokföring, kalkylering och budgetering. Detta då det beskrivs som att lantbrukare varken förstår eller använder redovisning för att sköta sitt lantbruk. Tidigare forskning tycks dock bortse från att lantbrukare ofta tillämpar en annan form av logik än den som förutsätts gälla inom redovisningsforskning. Det verkar också förutsättas att lantbrukarna ska kunna förstå och använda den redovisningsterminologi som finns inom forskningsvärlden trots att lantbrukarna ofta saknar utbildning inom redovisning. Mot denna bakgrund undersöker denna avhandling hur lantbrukare förstår och använder redovisning.Avhandlingen bygger på det grundläggande teoretiska perspektivet att se redovisning som ett språk för att på detta sätt förklara lantbrukarnas förståelse av redovisning. Avhandlingen bygger vidare på familjeföretagsforskning, speciellt socioemotional wealth (SEW), och beslutsteori för att förklara lantbrukarnas användning av redovisningsinformation.Den empiriska studien är inspirerad av grundad teori. Det empiriska materialet utgörs främst av intervjuer med mjölkbönder i Jönköpings län. Även intervjuer med rådgivare och bankmän och vissa sekundärdata har utgjort underlag för avhandlingen.Resultatet av undersökningen visar att lantbrukare har större kunskaper vad gäller redovisning än vad tidigare forskning indikerat. Delvis kan detta förklaras av att lantbrukare använder en annan terminologi än vad som vanligtvis används inom redovisningsforskning när de beskriver redovisning. Mjölkföretag drivs vanligen som familjeföretag och denna avhandling visar på en mycket stark familjeförankring i dessa företag. Det innebär att mjölkföretag ibland (speciellt vad gäller fastigheten) prioriterar annat än finansiella mål, vilket ofta kopplas samman med en intuitiv beslutsstil. Inom redovisning förutsätts generellt att finansiella mål är eftersträvansvärda. Lantbrukarnas sätt att se på redovisning påverkar också hur den används. Även om de förstår och använder redovisning är det inte säkert att den används på det mest vinstmaximerande sättet. I stället kan SEW vara det som prioriteras. Användning av redovisning anpassas efter den situation lantbrukaren befinner sig i. Vissa delar av redovisningen ses och förstås som speglingar av verkligheten eller som framåtriktade ledtrådar. När lantbrukare förstår redovisningen på så vis, uppfattas den som användbar för beslutsfattande. Andra delar av redovisningen ses som regelföljande, eller ibland till och med som helt frikopplad från själva verksamheten. Detta gäller framför allt redovisning till Skatteverket och Jordbruksverket. Dessa redovisningar används inte för beslut, men de är ändå rationellt utformade för att uppnå bästa möjliga utfall (skatteutjämning eller jordbruksstöd).

Decreased COPD prevalence in Sweden after decades of decrease in smoking
- 2020

In: Respiratory Research. - : Springer Nature. - 1465-9921 .- 1465-993X. ; 21
-
Journal article (peer-reviewed)abstract
- BackgroundCOPD has increased in prevalence worldwide over several decades until the first decade after the millennium shift. Evidence from a few recent population studies indicate that the prevalence may be levelling or even decreasing in some areas in Europe. Since the 1970s, a substantial and ongoing decrease in smoking prevalence has been observed in several European countries including Sweden. The aim of the current study was to estimate the prevalence, characteristics and risk factors for COPD in the Swedish general population. A further aim was to estimate the prevalence trend of COPD in Northern Sweden from 1994 to 2009.MethodsTwo large random population samples were invited to spirometry with bronchodilator testing and structured interviews in 2009–2012, one in south-western and one in northern Sweden, n = 1839 participants in total. The results from northern Sweden were compared to a study performed 15 years earlier in the same area and age-span. The diagnosis of COPD required both chronic airway obstruction (CAO) and the presence of respiratory symptoms, in line with the GOLD documents since 2017. CAO was defined as post-bronchodilator FEV1/FVC < 0.70, with sensitivity analyses based on the FEV1/FVC < lower limit of normal (LLN) criterion.ResultsBased on the fixed ratio definition, the prevalence of COPD was 7.0% (men 8.3%; women 5.8%) in 2009–2012. The prevalence of moderate to severe (GOLD ≥ 2) COPD was 3.5%. The LLN based results were about 30% lower. Smoking, occupational exposures, and older age were risk factors for COPD, whereof smoking was the most dominating risk factor. In northern Sweden the prevalence of COPD, particularly moderate to severe COPD, decreased significantly from 1994 to 2009, and the decrease followed a decrease in smoking.ConclusionsThe prevalence of COPD has decreased in Sweden, and the prevalence of moderate to severe COPD was particularly low. The decrease follows a major decrease in smoking prevalence over several decades, but smoking remained the dominating risk factor for COPD.

FEV1 decline in relation to blood eosinophils and neutrophils in a population-based asthma cohort
- 2020
-
In: World Allergy Organization Journal. - : Elsevier. - 1939-4551. ; 13:3
-
Journal article (peer-reviewed)abstract
- Background: The relationship between lung function decline and eosinophils and neutrophils has important therapeutic implications among asthmatics, but it has rarely been studied in large cohort studies.Objective: The aim is to study the relationship between blood eosinophils and neutrophils and FEV1 decline in a long-term follow-up of a population-based adult asthma cohort.Methods: In 2012-2014, an adult asthma cohort was invited to a follow-up including spirometry, blood sampling, and structured interviews, and n = 892 participated (55% women, mean age 59 y, 32-92 y). Blood eosinophils, neutrophils and FEV 1 decline were analyzed both as continuous variables and divided into categories with different cut-offs. Regression models adjusted for smoking, exposure to vapors, gas, dust, or fumes (VGDF), use of inhaled and oral corticosteroids, and other possible confounders were utilized to analyze the relationship between eosinophils and neutrophils at follow-up and FEV1 decline.Results: The mean follow-up time was 18 years, and the mean FEV 1 decline was 27 ml/year. The annual FEV1 decline was related to higher levels of both blood eosinophils and neutrophils at follow-up, but only the association with eosinophils remained when adjusted for confounders. Further, the association between FEV1 decline and eosinophils was stronger among those using ICS. With EOS <0.3 × 109/L as reference, a more rapid decline in FEV1 was independently related to EOS ≥0.4 × 109/L in adjusted analyses.Conclusions and clinical relevance: Besides emphasizing the importance of smoking cessation and reduction of other harmful exposures, our real-world results indicate that there is an independent relationship between blood eosinophils and FEV1 decline among adults with asthma.

Risk factors for severe asthma among adults with asthma
- 2020
-
In: European Respiratory Journal. - : European Respiratory Society (ERS). - 0903-1936 .- 1399-3003. ; 56:Suppl 64
-
Journal article (other academic/artistic)abstract
- Background: Severe asthma is a considerable challenge for patients, health care professionals and society, but there are few long-term studies on risk factors for severe asthma.Aim: To identify baseline risk factors of severe asthma in a longitudinal adult asthma cohort study.Methods: An adult asthma cohort was identified in 1986-2001 by clinical examinations of population samples within the OLIN studies in northern Sweden. The examinations included structured interviews, spirometry with reversibility testing, skin prick testing and metacholine challenge. The cohort was followed up in 2012-2014 when n=1006 participated (mean age 59y). Adjusted Risk Ratios (RR) for baseline factors as risk factors for GINA defined severe asthma (SA) at follow-up (n=51) were estimated by Poisson regression.Results: Older age, impaired lung function, increased reversibility and hyperreactivity, asthmatic wheeze, persistent wheeze, nighttime awakenings due to respiratory symptoms, and dyspnea were significant baseline risk factors for SA. Allergic sensitization, smoking, occupational groups or BMI did not predict SA. When adjusted for age, sex and smoking, post-bronchodilator FEV1/FVC<0.7, both present at baseline (RR 4.2, 95%CI 1.8-9.9) and developed during follow-up (2.9, 1.6-5.3), increased the risk. Also FEV1<80% at baseline associated with SA (2.9, 1.6-5.2). Triggers for respiratory symptoms at baseline such as tobacco smoke (2.1, 1.2-3.7) and physical activity (3.5, 1.5-81) associated with SA at follow-up, while pollen and furry animals did not.Conclusion: Among adults with asthma, impaired lung function, wheeze, dyspnea and nighttime awakenings due to respiratory symptoms are important long-term risk factors for severe asthma.

Meta-analysis of up to 622,409 individuals identifies 40 novel smoking behaviour associated genetic loci
- 2020

Journal article (peer-reviewed)abstract
- Smoking is a major heritable and modifiable risk factor for many diseases, including cancer, common respiratory disorders and cardiovascular diseases. Fourteen genetic loci have previously been associated with smoking behaviour-related traits. We tested up to 235,116 single nucleotide variants (SNVs) on the exome-array for association with smoking initiation, cigarettes per day, pack-years, and smoking cessation in a fixed effects meta-analysis of up to 61 studies (up to 346,813 participants). In a subset of 112,811 participants, a further one million SNVs were also genotyped and tested for association with the four smoking behaviour traits. SNV-trait associations with P < 5 × 10-8 in either analysis were taken forward for replication in up to 275,596 independent participants from UK Biobank. Lastly, a meta-analysis of the discovery and replication studies was performed. Sixteen SNVs were associated with at least one of the smoking behaviour traits (P < 5 × 10-8) in the discovery samples. Ten novel SNVs, including rs12616219 near TMEM182, were followed-up and five of them (rs462779 in REV3L, rs12780116 in CNNM2, rs1190736 in GPR101, rs11539157 in PJA1, and rs12616219 near TMEM182) replicated at a Bonferroni significance threshold (P < 4.5 × 10-3) with consistent direction of effect. A further 35 SNVs were associated with smoking behaviour traits in the discovery plus replication meta-analysis (up to 622,409 participants) including a rare SNV, rs150493199, in CCDC141 and two low-frequency SNVs in CEP350 and HDGFRP2. Functional follow-up implied that decreased expression of REV3L may lower the probability of smoking initiation. The novel loci will facilitate understanding the genetic aetiology of smoking behaviour and may lead to the identification of potential drug targets for smoking prevention and/or cessation.

Efficacy of hyperthermic intraperitoneal chemotherapy in colorectal cancer : A phase I and III open label randomized controlled registry-based clinical trial protocol
- 2024
-
In: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 19:3
-
Journal article (peer-reviewed)abstract
- Standard treatment for patient with peritoneal metastases from colorectal cancer is cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). In recent years, the efficacy of oxaliplatin-based HIPEC has been challenged. An intensified HIPEC (oxaliplatin+irinotecan) in combination with early postoperative intraperitoneal chemotherapy (EPIC) has shown increased recurrence-free survival in retrospective studies. The aim of this trial is to develop a new HIPEC/EPIC regimen and evaluate its effect on morbidity, oncological outcome, and quality-of-life (QoL). This study is designed as a combined phase I/III multicenter randomized trial (RCT) of patients with peritoneal metastases from colorectal cancer eligible for CRS-HIPEC. An initial phase I dose escalation study, designed as a 3+3 stepwise escalation, will determine the maximum tolerable dose of 5-Fluorouracil (5-FU) as 1-day EPIC, enrolling a total of 15–30 patients in 5 dose levels. In the phase III efficacy study, patients are randomly assigned intraoperatively to either the standard treatment with oxaliplatin HIPEC (control arm) or oxaliplatin/irinotecan-HIPEC in combination with single dose of 1-day 5-FU EPIC (experimental arm). 5-FU is administered intraoperatively after CRS-HIPEC and closure of the abdomen. The primary endpoint is 12-month recurrence-free survival. Secondary endpoints include 5-year overall survival, 5-year recurrence-free survival (registry based), postoperative complications, and QoL up to 3 years after study treatment. This phase I/III trial aims to identify a more effective treatment of colorectal peritoneal metastases by combination of HIPEC and EPIC.

Longitudinal plasma protein profiling of newly diagnosed type 2 diabetes
- 2021
-
In: EBioMedicine. - : Elsevier B.V.. - 2352-3964. ; 63
-
Journal article (peer-reviewed)abstract
- Background: Comprehensive proteomics profiling may offer new insights into the dysregulated metabolic milieu of type 2 diabetes, and in the future, serve as a useful tool for personalized medicine. This calls for a better understanding of circulating protein patterns at the early stage of type 2 diabetes as well as the dynamics of protein patterns during changes in metabolic status. Methods: To elucidate the systemic alterations in early-stage diabetes and to investigate the effects on the proteome during metabolic improvement, we measured 974 circulating proteins in 52 newly diagnosed, treatment-naïve type 2 diabetes subjects at baseline and after 1 and 3 months of guideline-based diabetes treatment, while comparing their protein profiles to that of 94 subjects without diabetes. Findings: Early stage type 2 diabetes was associated with distinct protein patterns, reflecting key metabolic syndrome features including insulin resistance, adiposity, hyperglycemia and liver steatosis. The protein profiles at baseline were attenuated during guideline-based diabetes treatment and several plasma proteins associated with metformin medication independently of metabolic variables, such as circulating EPCAM. Interpretation: The results advance our knowledge about the biochemical manifestations of type 2 diabetes and suggest that comprehensive protein profiling may serve as a useful tool for metabolic phenotyping and for elucidating the biological effects of diabetes treatments. Funding: This work was supported by the Swedish Heart and Lung Foundation, the Swedish Research Council, the Erling Persson Foundation, the Knut and Alice Wallenberg Foundation, and the Swedish state under the agreement between the Swedish government and the county councils (ALF-agreement).

Retinoic acid promotes differentiation of WiT49- but not of CCG99-11 Wilms tumour cells
- 2023
-
In: Cancer Reports. - 2573-8348. ; 6:6
-
Journal article (peer-reviewed)abstract
- Background: Most children with Wilms tumour are successfully treated with multidrug chemotherapy and surgery. These treatments cause severe side effects for the patients, an issue that needs to be addressed by exploring other treatment options with less or no side effects. One option is to complement current therapies with agents that could potentially induce tumour cell differentiation, for example retinoic acid (RA). Aims: To facilitate quick assessment of an agent's effect on Wilms tumour differentiation by a rapid in vitro model system. Methods and Results: Here WiT49 and CCG99-11 Wilms tumour cells were treated with 10 μM RA for 72 h or 9 days. Cultured cells were scraped off from Petri dishes, pelleted and embedded in paraffin in the same way as clinical tumour specimens are preserved. Cell morphology and differentiation were evaluated by analyses of haematoxylin eosin (H&E) and immunohistochemical stainings. Based on H&E, WT1 and CKAE1/3 stainings, RA treatment induced further epithelial differentiation of WiT49 cells, whereas there was no sign of induced maturation in CCG99-11 cells. Ki67 staining showed that RA inhibited cell proliferation in both cell lines. Conclusions: Our study shows that in vitro culturing of WiT49 and CCG99-11 cells, followed by pelleting and paraffin embedding of cell pellets, could aid in a quick evaluation of potential differentiating agents against Wilms tumour. In addition, our results strengthen previous results that retinoic acid could be a potential complement to regular Wilms tumour treatment.
