- A therapeutic removal of antibodies may be achieved by immunoadsorption (IA) or by plasma exchange (PE). The aim of this prospective randomised study was to compare the efficacy of these different techniques with regard to treatment of patients with rapidly progressive glomerulonephritis (RPG) having at least 50% crescents. Forty-four patients with a RPG were included for treatment either by IA or PE (with albumin as substitution for removed plasma). All patients were additionally treated with immunosuppression. A median of 6 sessions of PEs were performed in 23 patients compared with 6 IAs in 21 patients. Goodpasture's syndrome (GP) was present in 6 patients (PE 3, IA 3). All of them started and ended in dialysis, two died. Among the remaining 38 patients (26 men, 12 women) 87% had antibodies to ANCA. Creatinine clearance for PE versus IA were at a median at start 17.1 and 19.8 ml/min, and at 6 months 49 and 49 ml/min, respectively. At 6 months 7 of 10 patients did not need dialysis (remaining: IA 0/5 and PE 2/5, n.s.). The extent of improvement did not differ between the groups. Three patients died during the observation period of 6 months (IA 2; PE 1, on HD). Although no difference was found between the IA or the PE group this study shows that the protocol used was associated with an improved renal function in most patients (except for Goodpasture's syndrome) whereas 70% of them could leave the dialysis program.

Rekonstruktion av saknade projektioneri datortomografi
- 1991
-
Reports (other academic/artistic)abstract
- Vid datortomografi besväras de rekonstruerade bilderna ofta av störande artefakter, dvs strukturer i bilden som inte motsvarar strukturer i patienten. Det finns många olika orsaker till artefakter och en viktig orsak är att vissa projektioner saknas helt eller delvis eller är av otillräcklig kvalitet. Delar av projektioner kan exempelvis saknas när implantat av metallproteser eller plomber i tänderna skymmer anatomin för de projicerande strålarna. Saknade projektioner av ena eller andra slaget ger upphov till artefakter i form av raka linjer som störande breder ut sig över hela bilden, ofta på ett sådant sätt att bilden blir otjänlig för sitt ändamål. I detta projekt har vi valt att studera en möjlighet att rekonstruera så mycket av de projektioner som saknas i ett visst vinkelavsnitt, att de inte längre ger upphov till störande artefakter. Arbetet har utförts med simulerade modellförsök. Vi har antagit en skiva i anatomin som avbildats med datortomografi med användande av parallellprojektioner. Försök har gjorts där enstaka projektioner saknas, och där projektioner saknas inom ett större vinkelavsnitt. Vid beskrivningen av vår metod skall vi först ge en verbal beskrivning och därpå en matematisk.

The tribological efficiency and the mechanism of action of nano-porous composition base brake lining materials
- 2011
-
In: International Congress on Advances in Applied Physics and Materials Science. - : AIP. - 9780735409712 ; , s. 546-554
-
Conference paper (peer-reviewed)abstract
- Based on the comparative analysis of the experimental values determined for the tribological parameters for the three novel nano-porous composition base and two conventional brake lining materials while friction with the grey cast iron disc, it was shown the considerable high tribological efficiency of the novel nano-porous composition base lining materials in comparison with the conventional (from EU and USA market) brake lining materials. The explanation is given to the action mechanism of nano-porous composition base brake lining material and its tribological efficiency basing on the "triple phase" tribo-pair model.

Prehospital characteristics among patients with sepsis: a comparison between patients with or without adverse outcome
- 2019

In: Bmc Emergency Medicine. - : Springer Science and Business Media LLC. - 1471-227X. ; 19:1
-
Journal article (peer-reviewed)abstract
- Background The prehospital care of patients with sepsis are commonly performed by the emergency medical services. These patients may be critically ill and have high in-hospital mortality rates. Unfortunately, few patients with sepsis are identified by the emergency medical services, which can lead to delayed treatment and a worse prognosis. Therefore, early identification of patients with sepsis is important, and more information about the prehospital characteristics that can be used to identify these patients is needed. Based on this lack of information, the objectives of this study were to investigate the prehospital characteristics that are identified while patients with sepsis are being transported to the hospital by the emergency medical services, and to compare these values to those of the patients with and without adverse outcomes during their hospital stays. Methods This was a retrospective observational study. The patients' electronic health records were reviewed and selected consecutively based on the following: retrospectively diagnosed with sepsis and transported to an emergency department by the emergency medical services. Data were collected on demographics, prehospital characteristics and adverse outcomes, defined as the in-hospital mortality or treatment in the intensive care unit, and analysed by independent sample t-test and chi-square. Sensitivity, specificity and likelihood ratio, of prehospital characteristics for predicting or development of adverse outcome were analysed. Results In total, 327 patients were included. Of these, 50 patients had adverse outcomes. When comparing patients with or without an adverse outcome, decreased oxygen saturation and body temperature, increased serum glucose level and altered mental status during prehospital care were found to be associated with an adverse outcome. Conclusions The findings suggests that patients having a decreased oxygen saturation and body temperature, increased serum glucose level and altered mental status during prehospital care are at risk of a poorer patient prognosis and adverse outcome. Recognizing these prehospital characteristics may help to identify patients with sepsis early and improve their long-term outcomes. However further research is required to predict limit values of saturation and serum glucose and to validate the use of prehospital characteristics for adverse outcome in patients with sepsis.

The impact of exclusion due to COVID-19 restrictions on partners' satisfaction with Swedish hospital postnatal ward care: A multi-methods approach

Journal article (peer-reviewed)abstract
- BackgroundTo prevent the spread of SARS-CoV-2, hospitals around the world adopted protocols that, in varying ways, resulted in the exclusion of partners from hospital postnatal care wards. The objective of this study was to examine the effect this exclusion had on partners' satisfaction with postnatal care.MethodsAn online survey (the Swedish Pregnancy Panel) including free-text comments was conducted before and during the first wave of the COVID-19 pandemic; partners of pregnant women were recruited at an early ultrasound appointment and followed until 2 months after childbirth. Data were linked to the Swedish Pregnancy Register.ResultsThe survey was completed by 524 partners of women who gave birth during the pandemic and 203 partners of women who gave birth before. Partners' satisfaction with hospital postnatal care dropped 29.8 percent (-0.94 OLS, 95% CI = -1.17 to -0.72). The drop was largest for partners of first-time mothers (-1.40 OLS, 95% CI = -1.69 to -1.11), but unrelated to clinical outcomes such as mode of birth and most social backgrounds, except higher income. The qualitative analysis showed that partners (1) felt excluded as partners and parents, (2) thought the strain on staff led to deficiencies in the care provided, and (3) perceived the decision about partner restrictions as illogical.ConclusionsThe exclusion of partners from the hospital postnatal wards clearly impaired satisfaction with care, and partners of first-time mothers were particularly affected. Planning for future restrictions on partners from hospital wards should factor in these consequences. image
