- Background: Biliary complications during pregnancy is an important issue. The aim of this study was to examine if there is an increased risk to perform cholecystectomy during pregnancy in patients with previous bariatric surgery in comparison to other females subjected to cholecystectomy. Methods: The Nationwide Swedish Registry for Gallstone Surgery (GallRiks) and the Scandinavian Obesity Surgery Registry (SOReg) were combined. Female patients 18–45 years old were included. The study group was patients with a history of bariatric surgery whom were pregnant at the time of cholecystectomy. This group was compared with pregnant patients without previous bariatric surgery and non-pregnant with and without previous bariatric surgery. Results: In total, 21,314 patients were included and 292 underwent surgery during pregnancy. From 1282 patients identified in both registers, 16 patients were pregnant at the time of cholecystectomy. Acute cholecystectomy was performed in 5922 (28%) non-pregnant and 199 (68%) pregnant (p < 0.001), including 11/16 (69%) pregnant with previous bariatric surgery. When comparing all pregnant patients, those with previous bariatric surgery had longer operative time (p = 0.031) and length of stay (p = 0.043), but no differences were seen when only comparing patients with an acute indication for surgery. There was no difference in complications comparing pregnant patients with previous bariatric surgery with non-pregnant, both with and without previous bariatric surgery. Conclusions: Cholecystectomy during pregnancy in patients with previous bariatric surgery seems to be safe. The increased risk seen in the non-pregnant group after previous bariatric surgery is not seen in pregnancy, possibly due to an optimization of the circumstances at surgery.

Tidskriftsartikel (refereegranskat)abstract
- The magnetic properties of the (Fe,Mn)(2)(P,Si)-system have been shown to be readily manipulated by small changes in composition. This study surveys the FeMnP1-xSix-system (0.00 <= x <= 1.00) reporting sample syntheses and investigations of crystallographic and magnetic properties using X-ray powder diffraction and magnetic measurements. Two single phase regions exist: the orthorhombic Co2P-type structure (x < 0.15) and the Fe2P-type structure (0.24 <= x < 0.50). Certain compositions have potential for use in magnetocaloric applications.

Tidskriftsartikel (refereegranskat)abstract
- The structural and magnetic properties of the Dy2CoMnO6, Dy2NiMnO6 and Gd2CoMnO6 double perovskites are investigated using X-ray powder diffraction and squid magnetometry. The materials adopt an orthorhombic structure (space ground Pnma) with disordered Co(Ni)/Mn cations, and exhibit ferrimagnetic transitions near T(C)85, 95, and 115K respectively. T-C was found to monotonously depend on the orthorhombic distortion (a-c)/(a+c) of the compounds. The crystal structure of the compounds was investigated as a function of temperature (16-1100K range), evidencing changes in the BO6 octahedron near T-C. The magnetic entropy changes are estimated for comparison of the magnetocaloric properties to those from literature.

En ekonomisk utvärdering av inverkan av marknära ozon på växtligheten i Sverige
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Med finansiering från Naturvårdsverket har forskare från IVL, SMHI, Göteborgs Universitet samt SLU genomfört en analys av de ekonomiska värdena av den negativa inverkan av marknära ozon på växtligheten i Sverige vid olika scenarier för ozonbelastning och i relation till föreslagna målvärden vad gäller preciseringen för ozon och växtlighet inom miljömålet Frisk Luft. Arbetet utgör i stor utsträckning en uppdatering av en tidigare studie från 2006 (Karlsson m. fl., 2006a). Tre olika scenarier för ozonbelastning analyserades: 1. Nuvarande ozonbelastning (2006-2012). 2. Ett scenario där målvärdet för ozon och växtlighet inom miljömålet Frisk Luft inte överskrids vid någon plats i landet. 3. Ett förindustriellt scenario i avsaknad av ozonbelastning, dvs där ozonhalten 80 μg/m3 aldrig överskreds och där AOT40 april-september således var noll över hela Sverige. Uppskattningar har gjorts för tillväxten hos några viktiga trädslag samt för skördeutbytet för vissa viktiga jordbruksgrödor. Utifrån en genomgång av ny vetenskaplig kunskap som framkommit sedan den föregående studien 2006, föreslås en höjning av den negativa ozoneffekten på stamtillväxten hos gran från -2 % till -5 % per 20 000 μg/m3 timmar AOT40 april-september. AOT40 20 000 μg/m3 timmar är en vanligt förekommande nivå på ozonbelastningen vid utsatta platser i södra Sverige. För tall föreslås samma ozoneffekt på stamtillväxten som hos gran. För lövträd föreslås att ozoneffekten på stamtillväxten kvarstår på -8 % per 20 000 μg/m3 timmar AOT40 april-september. Dos-respons-relationerna för vete inom konventionen om gränsöverskridande luftföroreningar (LRTAP) har i viss utsträckning uppdaterats sedan 2006. På grund av dessa uppdateringer har dos-responssambandet för vete förändrats något jämfört med föregående studie. Förändringen är dock av mycket liten betydelse för tolkningen av resultaten. Nuvarande ozonbelastning 2006-2012 beräknades minska skogstillväxten som ett summerat värde för alla landsdelar och trädslag i Sverige med 2.9 Mm3 år-1, i jämförelse med ett förindustriellt scenario i avsaknad av ozonbelastning, vilket motsvarar en procentuell minskning av tillväxten på -3.2 %. Detta värde varierade mellan -1.6 och -4,9 %, beroende på landsdel och trädslag. I ett scenario där målvärdet för ozon och växtlighet inom miljömålet Frisk Luft inte överskrids reducerades den negativa inverkan av ozon till ett medelvärde på -1.2 %, och varierade mellan -0.6 och -2.1 %. Det ekonomiska värdet av den minskade skogstillväxten beroende på nuvarande ozonbelastning beräknades till 733 MSEK år-1, ett värde som är mer än dubbelt så högt jämfört med motsvarande värde som beräknades vid den tidigare studien 2006. Skillnaden beror på att den ozonbelastning som beräknades över Sverige var högre i den nya studien, särskilt i norra Sverige, men framför allt beror det på höjning av den negativa ozoneffekten på stamtillväxten hos gran och tall. I det scenario där målvärdet för ozon och växtlighet inom miljömålet Frisk Luft inte överskrids beräknades det ekonomiska värdet för tillväxtnedsättningen orsakad av ozon till 293 MSEK år-1, det vill säga mer än en halvering jämfört med nuvarande ozonbelastning. De summerade skördeförlusterna beroende på nuvarande ozonbelastning vad gäller alla sädesslag för alla delar av Sverige beräknades separat för olika år och uppgick till som högst 88 kton för 2006 och till 6 kton för 2008. Motsvande värden för potatis uppgick till 52 kton för 2006 och till 14 kton för 2012. De beräknade ekonomiska värdena för dessa summerade skördenedsättningar beräknades till i medeltal 180 MSEK år-1. Mellanårsvariationen var dock stor och för 2006 beräknades ett samlat värde av 420 MSEK år-1. För ett scenario där målvärdet för ozon och växtlighet inom miljömålet Frisk Luft inte överskrids beräknades ett samlat värde av ozonets negativa inverkan på skördeutbytet till i medeltal 74 MSEK år-1. Sammantaget beräknades det ekonomiska värdet för inverkan av nuvarande ozonbelastning på skogstillväxt och skördebortfall inom jordbruket i Sverige till 913 MSEK år-1. Motsvarande värde för ett scenario där målvärdet för ozon och växtlighet inom miljömålet Frisk Luft inte överskrids vid någon plats i landet uppgick till 367 MSEK år-1. I bägge fallen gäller en jämförelse med ett förindustriellt scenario i avsaknad av ozonbelastning, dvs när ozonkoncentrationerna aldrig överskred 80 μg/m3 (40 ppb).

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Civil actions are a regular occurrence during the course of bankruptcy proceedings and may have wide-ranging and significant social impacts, not least due to the fact that they can pertain to assets of considerable value or affect a large number of individuals and various types of economic interests. These lawsuits also raise a number of legal issues regarding the delimitation of procedural rights of various bankruptcy actors, such as the bankruptcy trustee, the bankruptcy debtor and individual creditors.The mentioned competence issues are complex and have over the years generated relatively extensive case law. Additionally, they are of great importance in a bankruptcy, as they have a major impact on the outcome of bankruptcy proceedings and on the furthering of the efficacy of the policies underlying bankruptcy law.This thesis aims at systematizing and evaluating the rules regarding the bankruptcy actors' competence in civil proceedings to directly or indirectly dispose of assets and liabilities that are subject to a process by way of litigation. It is further intended to investigate how these rules affect the impact of the policy aims behind the substantive competence rules of bankruptcy law and the main purpose of the bankruptcy, and whether the regulation constitutes acceptable coordination between substantive bankruptcy law and procedural law.The investigation covers a very large number of legal issues at the intersection of substantive bankruptcy law and general procedural rules governing civil proceedings, for example: Who may be a party or intervener in actions regarding assets or debts in the bankruptcy? What are the legal implications of the estate substituting the debtor as a party to an action? What prospects does a bankruptcy estate have to avoid being drawn into the bankruptcy debtor's actions? To what extent are judgments in the debtor’s actions binding in bankruptcy proceedings?The inquiry shows that the relationship between the substantive and procedural rights of the individual bankruptcy actors is complex. In a number of situations, individual bankruptcy actors have a more wide-ranging procedural right of disposal regarding assets or liabilities than a substantive one. This gives rise to a risk that these rights will be used in ways that limit the impact for the policy aims of bankruptcy law, for example, by circumventing rules to protect third parties. However, it is argued that a more wide-ranging procedural right of disposal can, in certain instances, further the policies underlying bankruptcy law, provided that the relevant procedural rights are adequately set out. The thesis also discusses various solutions regarding the delimitation of the individual bankruptcy actors' procedural rights.

A comprehensive dataset on spatiotemporal variation of microbial plankton communities in the Baltic Sea
- 2024
-
Ingår i: Scientific Data. - : Springer Nature. - 2052-4463. ; 11:1
-
Tidskriftsartikel (refereegranskat)abstract
- The Baltic Sea is one of the largest brackish water environments on earth and is characterised by pronounced physicochemical gradients and seasonal dynamics. Although the Baltic Sea has a long history of microscopy-based plankton monitoring, DNA-based metabarcoding has so far mainly been limited to individual transect cruises or time-series of single stations. Here we report a dataset covering spatiotemporal variation in prokaryotic and eukaryotic microbial communities and physicochemical parameters. Within 13-months between January 2019 and February 2020, 341 water samples were collected at 22 stations during monthly cruises along the salinity gradient. Both salinity and seasonality are strongly reflected in the data. Since the dataset was generated with both metabarcoding and microscopy-based methods, it provides unique opportunities for both technical and ecological analyses, and is a valuable biodiversity reference for future studies, in the prospect of climate change.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background and aims: In order to make fair comparisons between the results of different health care providers, proper consideration of the casemix of the populations they serve is important. HbA1c is often used as a metric to indicate the quality of diabetes care, it is therefore of value to determine what patient characteristics affect this outcome. As part of the ongoing National Collaboration for Value Based Reimbursement and Monitoring Systems, we therefore set out to investigate what factors are associated with HbA1c in a large retrospective cohort of persons with type 1 diabetes.Materials and methods: This was a retrospective register study where we analyzed persons 18 years or older, with a health care contact and a diagnosis of diabetes during 2010-11 in the administrative systems of seven Swedish county councils (Dalarna, Jämtland Härjedalen, Skåne, Stockholm, Uppsala, Västra Götaland and Östergötland), covering ~70% of the Swedish population and linked this data to data from the National Diabetes Register, socioeconomic data from Statistics Sweden and data on filled prescriptions from the Prescribed Drug Register. We estimated a random effect model on HbA1c after one year of follow-up, including socioeconomic, demographic and clinical factors.Results: Based on a complete case approach, 13 396 patients were analyzed. Women had on average higher HbA1c than men. Blood sugar control seemed to be better with higher age. Of the socioeconomic factors, higher education was associated with lower levels of HbA1c, as was being married. By contrast, we found no association between HbA1c and being born outside the EU.Ahistory (previous 2 years) of diabetes related complications were associated with higher levels of HbA1c, which is likely due to high levels of HbA1c being an indicator of what is causing the complications in the first place. The exception to this pattern was patients with renal failure.Conclusion: Apart from obvious demographic factors such as age and gender as well as disease history, educational and civil status are important factors to take into consideration when comparing obtained HbA1c levels between health care providers. This also raises the question of the need for additional focus on education directed towards these groups to facilitate improved diabetes management.
