- To clinically measure blood pressure at extra corporeal bloodlines involves a hazard due to the infection risk and a risk for thrombosis formation. The aim was to design a non-invasive pressure sensor, measuring directly on a tube section. A modified tube cross-section was used to improve sensitivity. Using the developed sensing principle, a consistent relation (r=0.999) was obtained between pressure and output signal. The output was stable and an acceptable drift within the temperature-range. The method shows great promise for applications in monitoring of the dialysis process.

- While genealogy is a practice occupied with questions of roots and belonging, it is also concerned with tracing ancestors outside of national borders. Notions of belonging to history and culture are highlighted through international migration. What does belonging mean for individuals who has historical and contemporary family spread over different countries? How are notions of belonging negotiated in the meeting of different national identities? And how are these processes mediated through genealogy, a project occupied with tracing common bloodlines? This article explores these questions through the case of Swedish-American genealogy. More specifically, it analyzes how this genealogy is represented on contemporary television through the popular TV-show Allt för Sverige.

The Terms of Ethnoracial Equality : The Swedish Courts' Reading of Ethnic Affiliation, Race and Culture
- 2018
-
Ingår i: Social & Legal Studies. - : SAGE Publications. - 0964-6639 .- 1461-7390. ; 27:5, s. 616-635
-
Tidskriftsartikel (refereegranskat)abstract
- This article initially accounts for the discussions concerning the notions ‘ethnic origin’ and ‘race’ that have taken place in the Swedish legislative context and places these within a wider European context. Next follows a mapping of the ways in which Swedish courts, in cases of alleged ethnic discrimination, read the notion of ‘ethnic affiliation’ – defined as ‘national or ethnic origin, skin colour, or other similar circumstance’ – and decide whether a statement or an act is related to it. The purpose, to borrow Michel Foucault’s words, is to ‘make visible precisely what is visible’. By bringing together, arranging and connecting what the courts have said about ‘ethnic affiliation’, the conclusions they have reached and the circumstances that they have ignored, three observations are made: (a) ethnic affiliation is treated as an authentic and stable personal individual attribute, (b) ethnic affiliation is seen as a question about body types and bloodlines solely and (c) discriminatory acts are connected to ‘ethnic affiliation’ only if related to visual appearance or accompanied by ‘incriminating words’. The article discusses and analyzes the significance and implications of these observations in engagement with theorists such as Barnor Hesse and David Theo Goldberg.

Microemboli induced by air bubbles may be deposited in organs as a consequence of contamination during medical care
- 2023

Ingår i: Clinical Kidney Journal. - : Oxford University Press. - 2048-8505 .- 2048-8513. ; 16:1, s. 159-166

Tidskriftsartikel (refereegranskat)abstract
- Background: Larger volumes of accidental air infused during medical care may end up as emboli while microbubbles of air are supposed to be absorbed and cause no harm. The aim of this autopsy study was to investigate if microbubbles of air accidently entering the bloodline may be detected as microemboli (ME) in tissue such as lungs, brain and heart. If so, do differences in prevalence exist between haemodialysis (HD) and amyotrophic lateral sclerosis (ALS) patients.Methods: Included were data from 44 patients treated by medical healthcare before death. Twenty-five cases had been treated with chronic HD and 19 cases died from ALS. Since air in the bloodline activates coagulation, ME could appear. To discriminate between microbubbles caused by artificial contamination during autopsy versus microbubbles deposited in vivo, tissues were stained with a polyclonal fluorescent antibody against fibrinogen, fibrin and fragments E and D. Fluorescence staining was used to visualize ME counted within 25 microscopic fields (600x) of a tissue preparation. One tissue preparation was used if available from the lung, heart and frontal lobe of the brain and in five cases also the cerebellum.Results: Microbubbles can be verified at autopsy as ME in the lung, heart and brain in tissue from patients exposed to more extensive medical care. There were significantly more ME in the lungs versus the heart or brain. Women had fewer ME than men. The HD group had a higher median of ME per section than the ALS group (lung: 6 versus 3, P = .007; heart: 2.5 versus 1, P = .013; brain: 7.5 versus 2, P = .001) and had more sections with ME findings than the ALS group (P = .002). A correlation existed between the time on HD (months) and ME in the lungs.Conclusions: More ME were present in HD patients compared with those who suffered from ALS. Minimizing air contamination from syringes, infusions and bloodlines will decrease ME and subsequent tissue injury. Lay Summary Larger volumes of accidental air infused during medical care may end up as emboli while microbubbles of air are supposed to be absorbed and cause no harm. Microbubbles can be verified at autopsy as microemboli (ME) by air in lung, heart and brain in tissue from patients exposed to dialysis and more cannulation and infusions. Minimizing air exposure from syringes, infusions and bloodlines may decrease the risk of ME by air and subsequent tissue injury.

Farmers' Relationship with Different Animals: The Importance of Getting Close to the Animals - Case Studies of French, Swedish and Dutch Cattle, Pig and Poultry Farmers.

Tidskriftsartikel (refereegranskat)abstract
- The article analyses how cattle and poultry farmers in the Netherlands described their relationship with their farm animals and explores the factors that influence their level of attachment to them. The analysis draws upon Willkie’s (2005) framework of farmer-animal relationship, which distinguishes between different levels of attachment and detachment. This framework was useful for explaining why farmers developed different levels of attachment to animals, with the species, farm sector and housing system all playing roles in influencing this. Farmers tended to be more attached to cows than to chickens and felt more attachment towards breeding, as opposed to fattening, animals. Breeding, especially of cows, linked the animal to the personal histories of farmers, since their ancestors had often established the bloodlines of dairy cows. Farmers’ relationships with their animals were also influenced by the organization of production at the farm: the number of animals, their length of stay on the farm and the housing system. These factors all influenced the visibility of the animal as an individual and as a ‘real’ animal and not a living tool of production. The species and function of an animal and the organization of production largely defined the frequency, intensity and intimacy of farmers’ contact with individual animals. Practically all farmers (across sectors) perceived taking good care of animals and avoidance of suffering as a core element of their job and caring about animals as central to their definition of a ‘good farmer’. Beyond this, different groups of farmers showed clear differences in their level of attachment to their animals. In general dairy farmers felt more strongly attached to their dairy cows than farmers to their beef cattle or veal, whereas most poultry farmers felt rather detached from their chicken, and tended to perceive them as part of a flock and ‘living production tools’. These animals were not only de-individualized; at times and when seen solely as part of a meat and egg production system they were almost de-animalized.

Formation of Blood Foam in the Air Trap During Hemodialysis Due to Insufficient Automatic Priming of Dialyzers
- 2018

- We were encouraged to investigate the reasons for large amounts of foam observed in bloodlines during hemodialysis (HD). Foam was visible in the venous air trap within the Artis Gambro dialysis device. Estimates of the extent of foam were graded (0no foam, 10extensive foam) by two persons that were blind to the type of dialyzer used. Thirty-seven patients were involved in the dialysis procedures. Consecutive dialyses were graded using dialyzers from Fresenius Medical Care (CorDiax dialyzers that were used for high flux HDFX80 and FX100, and for hemodiafiltrationFX1000). The extracorporeal circuit was primed automatically by dialysate using Gambro Artis software 8.15 006 (Gambro, Dasco, Medolla Italy, Baxter, Chicago, IL, USA). The priming volume recommended by the manufacturer was 1100 mL, whereas our center uses 1500 mL. Extensive amounts of blood foam were visual in the air traps. Although the manufacturer recommended extension of priming volume up to 3000 mL, this did not eliminate the foam. Microbubble measurement during HD revealed the air to derive from the dialyzers. When changing to PF210H dialyzers (Baxter) and using a priming volume of 1500 mL, the foam was significantly less (P<0.01). The extent of foam correlated with the size of the FX-dialyzer surface (P=0.002). The auto-priming program was updated to version 8.21 by the manufacturer and the extent of foam in the air trap using FX dialyzers was now reduced and there was no longer a difference between FX and PF dialyzers, although less foam was still visible in the venous air trap during several dialyses. In conclusion, this study urgently calls attention to blood foam development in the venous air trap when using Artis devices and priming software 8.15 in combination with Fresenius dialyzers. Updated auto-priming software (version 8.21) of Artis should be requested to reduce the extent of foam for the Fresenius dialyzers. Other interactions may also be present. We recommend further studies to clarify these problems. Meanwhile caution is warranted for the combined use of dialysis devices and dialyzers with incompatible automatic priming.
