- Objective. Postoperative urinary retention and bladder distension are frequent complications of surgery. The aim of this study was to determine the incidence of perioperative bladder distension in a surgical setting and to identify predisposing factors among patients undergoing common general and orthopaedic procedures. Material and methods. This was a prospective observational study of 147 adult patients admitted to orthopaedic and surgical departments. Bladder volumes were measured with an ultrasound scanner on three occasions: after emptying the bladder before being transported to the operating theatre, and then immediately before and after surgery. Results. Thirty-three patients (22%) developed bladder distension (500 ml), eight preoperatively and 25 postoperatively. A total of 21 patients (14%) had a bladder volume 300 ml immediately before surgery. Orthopaedic patients were more likely to develop preoperative bladder distension than surgical patients and had significantly higher postvoid residual volumes. In the binary logistic regression analysis age, gender and time of anaesthesia could not predict bladder distension. Patients undergoing orthopaedic surgical procedures, however, were prone to bladder distension (odds ratio 6.87, 95% confidence interval 1.76 to 26.79, p=0.006). Conclusions. This study shows that orthopaedic surgical patients are more prone to bladder distension perioperatively. The conventional method of encouraging patients to void at the ward before being transported to the operating theatre does not necessarily mean an empty bladder at the start of the operation.

Tidskriftsartikel (refereegranskat)abstract
- Purpose The aim of this study was to investigate within-cycle differences in nocturnal heart rate (HR) and heart rate variability (HRV) in naturally menstruating women (NM) and women using combined hormonal contraceptives (CU) or progestin-only hormonal contraceptives (PU).Methods Physically active participants were recruited into three groups: NM (n = 19), CU (n = 11), and PU (n = 12). Participants’ HR and HRV (with Bodyguard 2 HRV monitor), and blood hormones were monitored during one menstrual cycle (MC) (NM-group) or for 4 weeks (CU and PU-groups). Estradiol, progesterone, and luteinizing hormone were analyzed from fasting blood samples collected four times in the NM (M1 = bleeding, M2 = follicular phase, M3 = ovulation, and M4 = luteal phase) and PU groups (M1 = lowest E2; M2 = M1 + 7 days; M3 = M1 + 14 days; M4 = M1 + 21 days) and twice in the CU group (active and inactive pill phases). After every blood sample, nightly HR and HRV were recorded and examined as an average from two nights.Results Hormonal concentrations differed (p < 0.05) between MC phases in the NM- and PU-groups, but not (p ≥ 0.116) between the active and inactive phases in the CU-group. In the NM- and PU-groups, some of the HRV values were higher, while in the NM-group, HR was lower during M2 compared to M3 (p < 0.049) and M4 (p < 0.035). In the CU-group, HRV values (p = 0.014-0.038) were higher, and HR was lower (p = 0.038) in the inactive phase compared to the first week of the active phase.Conclusions The MC and hormonal cycle phases influence autonomic nervous system balance, which is reflected in measurements of nocturnal HR and HRV. This should be considered when monitoring recovery in physically active individuals.

- Background Allergic contact dermatitis has considerable public health impact and causative haptens vary over time. Objectives To report the prevalence of contact allergy to allergens in the Swedish baseline series 2010 to 2017, as registered in the Swedish Patch Test Register. Methods Results and demographic information for patients tested with the Swedish baseline series in 2010 to 2017 were analysed. Results Data for 21 663 individuals (females 69%) were included. Females had significantly more positive patch tests (54% vs 40%). The reaction prevalence rates were highest for nickel sulfate (20.7%), fragrance mix I (7.1%), Myroxylon pereirae (6.9%), potassium dichromate (6.9%), cobalt chloride (6.8%), methylchloroisothiazolinone/methylisothiazolinone (MCI/MI; 6.4%), MI (3.7%), colophonium (3.5%), fragrance mix II (3.2%), and formaldehyde (3.2%). Myroxylon pereirae reaction prevalence increased from 5% in 2010 to 9% in 2017 and that for methyldibromo glutaronitrile from 3.1% to 4.6%. MCI/MI and MI reactions decreased in prevalence after 2014. Nickel reaction prevalence decreased among females aged 10 to 19 years. Conclusions Nickel remains the most common sensitizing agent, with reaction prevalence decreasing among females younger than 20 years. The changes in MCI/MI and MI reaction prevalence mirrored those in Europe. The register can reveal changes in contact allergy prevalence over time among patients patch tested in Sweden.

Neutrophil Extracellular Traps (NETs) in the Cerebrospinal Fluid Samples from Children and Adults with Central Nervous System Infections.
- 2020

Ingår i: Cells. - : MDPI AG. - 2073-4409. ; 9:1

Tidskriftsartikel (refereegranskat)abstract
- Neutrophils operate as part of the innate defence in the skin and may eliminate the Borrelia spirochaete via phagocytosis, oxidative bursts, and hydrolytic enzymes. However, their importance in Lyme neuroborreliosis (LNB) is unclear. Neutrophil extracellular trap (NET) formation, which is associated with the production of reactive oxygen species, involves the extrusion of the neutrophil DNA to form traps that incapacitate bacteria and immobilise viruses. Meanwhile, NET formation has recently been studied in pneumococcal meningitis, the role of NETs in other central nervous system (CNS) infections has previously not been studied. Here, cerebrospinal fluid (CSF) samples from clinically well-characterised children (N = 111) and adults (N = 64) with LNB and other CNS infections were analysed for NETs (DNA/myeloperoxidase complexes) and elastase activity. NETs were detected more frequently in the children than the adults (p = 0.01). NET presence was associated with higher CSF levels of CXCL1 (p < 0.001), CXCL6 (p = 0.007), CXCL8 (p = 0.003), CXCL10 (p < 0.001), MMP-9 (p = 0.002), TNF (p = 0.02), IL-6 (p < 0.001), and IL-17A (p = 0.03). NETs were associated with fever (p = 0.002) and correlated with polynuclear pleocytosis (rs = 0.53, p < 0.0001). We show that neutrophil activation and active NET formation occur in the CSF samples of children and adults with CNS infections, mainly caused by Borrelia and neurotropic viruses. The role of NETs in the early phase of viral/bacterial CNS infections warrants further investigation.

The Arctic plant aboveground biomass synthesis dataset
- 2024

Ingår i: Scientific Data. - : Springer Nature. - 2052-4463. ; 11:1
-
Tidskriftsartikel (refereegranskat)abstract
- Plant biomass is a fundamental ecosystem attribute that is sensitive to rapid climatic changes occurring in the Arctic. Nevertheless, measuring plant biomass in the Arctic is logistically challenging and resource intensive. Lack of accessible field data hinders efforts to understand the amount, composition, distribution, and changes in plant biomass in these northern ecosystems. Here, we present The Arctic plant aboveground biomass synthesis dataset, which includes field measurements of lichen, bryophyte, herb, shrub, and/or tree aboveground biomass (g m−2) on 2,327 sample plots from 636 field sites in seven countries. We created the synthesis dataset by assembling and harmonizing 32 individual datasets. Aboveground biomass was primarily quantified by harvesting sample plots during mid- to late-summer, though tree and often tall shrub biomass were quantified using surveys and allometric models. Each biomass measurement is associated with metadata including sample date, location, method, data source, and other information. This unique dataset can be leveraged to monitor, map, and model plant biomass across the rapidly warming Arctic.

Socialtjänstens brottsförebyggande arbete ur ungas perspektiv
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Sverige har en lång historia av brottsförebyggande initiativ för att tidigt upptäcka ungdomar som är involverade i brottslighet eller befinner sig i kriminella miljöer. På operativ nivå involverar samarbetet främst socialtjänst och polis. Socialtjänsten i Trollhättans Stad har under 2021–2022 genomfört brottsförebyggande insatser inom ramen för projektet Tidig upptäckt – tidig insats (TUTI). Den här rapporten redovisar den följeforskning som bedrivits i anslutning till arbetet.TUTI bygger på tidiga interventioner, delaktighet och samverkan, såväl övergripande som i det enskilda fallet. Ambitionen med projektet var att minska risken för att unga 9–17 år utvecklar en kriminell livsstil samt förebygga risk för kriminalitet, missbruk, psykisk ohälsa och utanförskap. Detta genom att systematisera det arbete med brottsförebyggande insatser gällande unga förstagångslagöverträdare som sker i samverkan mellan socialtjänst, polis, åklagare och civilsamhälle.Följeforskningen har kartlagt typ av och bakgrund till orosanmälningar för unga 9–17 år i Trollhättans Stad samt undersökt ungas egna erfarenheter och förståelse av socialtjänstens brottsförebyggande insatser (TUTI-insatser). I studien har både kvantitativa och kvalitativa datainsamlingsmetoder använts. Data har tagits fram dels på aggregerad nivå gällande orosanmälningar i Trollhättans Stad under perioden 2017–2022, dels gällande de 196 unga som under perioden 2021–2022 erbjöds socialtjänstens brottsförebyggande insatser. Orsaker till orosanmälan var främst ringa stöld (30%), misshandel/våld/hot (20%) samt ringa narkotikabrott (20%). Ungefär hälften av de som erbjöds brottsförebyggande insatser tackade ja till insats. 21 av dessa deltog i återkommande kvalitativa intervjuer. Totalt genomfördes 41 intervjuer.Majoriteten av de intervjuade uppger vid uppföljningen cirka ett år efter den första intervjun att de inte har haft någon ny kontakt med socialtjänsten och att TUTI-stödet har förstärkt deras kapacitet att inte begå någon ny lagöverträdelse. Alla vittnar om att de redan vid tidpunkten för händelsen bestämt sig för att det var dumt gjort, men för några av dem var rentav det väsentligt att de fick stöd att vidmakthålla beslutet. De unga berättar att de har lärt sig mer om sig själva och utvecklat sin förmåga att ta positiva snarare än negativa beslut.För att förstå unga som för första gången kommer i kontakt med samhällets representanter när de misstänks för ett brott, har materialet analyserats med hjälp av modellen för proceduriell rättvisa (Tyler & Blader, 2003). Resultaten visar att de unga har högt förtroende för samhällets reaktion och ger legitimitet till det stöd som ges i kedjan av insatser: polis, mottagningsgrupp och familjebehandlare. Sammantaget kan vi konstatera att unga som genomgått hela TUTI-kedjan upplever samhällets reaktion vid sin första lagöverträdelse som positiv.

Konferensbidrag (refereegranskat)abstract
- In this symposium, we will discuss different ways of analysing mathematics textbooks from a methodological point of view. The discussion will be based on examples from five separate ongoing analyses of Swedish textbooks divided into two methodological approaches; one where analysis is conducted within an established theoretical framework, and one where analytical tools are constructed through combining aspects of different theories. The symposium will be held at the conference MADIF-13.

This geographical area is hyperendemic for both Lyme borreliosis (LB) and Tick-borne encephalitis (TBE). Blood samples and ticks were collected from 100 tick-bitten volunteers. A total of 425 ticks was collected, all determined to Ixodes ricinus using molecular tools. Of them 20% contained Borrelia species, of which B. garinii and B. afzelii were most common. None contained the TBE virus (TBEV). Blood samples were drawn in conjunction with the tick bite, and eight weeks later. Sera were analyzed for Borrelia- and TBEV-specific antibodies using an ELISA and a semiquantitative antibody assay. In total 14% seroconverted in Borrelia C6IgG1, 3% in TBEV IgG, and 2% in TBEV IgM. Five participants developed clinical manifestations of LB. The high seroprevalence of both Borrelia (57%) and TBEV (52%) antibodies are likely attributed to the endemic status of the corresponding infections as well as the TBE vaccination program. Despite the similar prevalence of Borrelia spp. detected in ticks in other parts of Europe, the infection rate in this population is high. The AxBioTick study is continuing to investigate more participants and ticks for co-infections, and to characterize the dermal immune response following a tick bite.

Tidskriftsartikel (refereegranskat)abstract
- Climate change, globalization, urbanization, social isolation, and increased interconnectednessbetween physical, human, and technological systems pose major challenges to disaster risk reduction(DRR). Subsequently, economic losses caused by natural hazards are increasing in many regions of theworld, despite scientific progress, persistent policy action, and international cooperation. We argue thatthese dramatic figures call for novel scientific approaches and new types of data collection to integratethe two main approaches that still dominate the science underpinning DRR: the hazard paradigm and thevulnerability paradigm. Building from these two approaches, here we propose a research framework thatspecifies the scope of enquiry, concepts, and general relations among phenomena. We then discuss theessential steps to advance systematic empirical research and evidence-based DRR policy action.
