Tidskriftsartikel (refereegranskat)abstract
- Investments in iron ore mining and iron works as well as running business in this range of operations are long-term activities characterized by limited flexibility. This article therefore, as a background, starts with a description of the conditions before World War I for these very important trades in Swedish economy. This overview also provides an insight into the dimensions of the effects of World War I on a small neutral nation with long traditions within these industrial fields. How did these industries develop under the new conditions caused by the war?.

Bok (övrigt vetenskapligt/konstnärligt)abstract
- Medlemmar av familjen Keiller spelade en viktig roll för Göteborgs indutrialisering under 1800-talet. So ägaqre till Keillers Mekaniska Verkstad vid Skeppsbron - föregångare till Götaverken - levererade de mekanisk utrustning till andra industrier och medverkade till uppbyggnaden av en modern infrastruktur, gasverk, broar, järnvägsmateriel. Familjen engagerade sig också i gruvbrytning och koppartiillverkning i Bregslagen

Tidskriftsartikel (refereegranskat)abstract
- Conditioned normality - stories of (ab)normal life during and after secure care placementsSecure care for young people has an ambiguous mission. It is supposed to socially integrate troubled young people into society by excluding them from the same. As such, young people are supposed to be normalised by abnormal interventions. Young people in secure care also experience the placement as deviant. In this study, we depart from a relational understanding of normality and stories of apology, ‘sad tales’, to explore how young people understand and do normality during and after placement in secure.This interview-based study builds on almost a decade-long engagement with 11 young people, following their lives after institutional placement. The analysis demonstrates three different ways of doing normality: 1) integrating the normalisation practices of the institution in their current life, 2) distancing and, if possible, hiding their experiences from others and, 3) isolating themselves from overly close relationships because of repeated betrayals from adults. Although different in character, these three ways are underpinned by a focus on self-reliance and independence, and an emergent need ‘to behave’.This study is a reminder that institutional practices of normality create a feeling of being deviant many years after leaving the institution. Thus, the need for developing supporting structures and relations that acknowledge and address the young people’s experiences of abnormality and in such way enable them to feel respected, valued and cared for, is emphasised.

Protamine, Platelet Function and Coagulation in Cardiac Surgery
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Bleeding is a serious and common complication in cardiac surgery. Complicated surgery together with alterations in hemostatic conditions from the use of cardiopulmonary bypass (CPB), presents challenges in how to preserve hemostasis in the patient. CPB is thought to affect platelet function and coagulation in many ways. Before connecting the patient to the CPB system, heparin is used as anticoagulation. With the connection between the patient and the CPB tubing there is a dilution of platelets and coagulation proteins and despite anticoagulation there is an activation of coagulation and inflammation resulting in consumption of coagulation factors and triggering of fibrinolysis. After disconnection of the CPB system, protamine is used to reverse the effect of heparin and restore the coagulation capacity of the patient. When protamine binds to heparin, the anticoagulant effect of heparin is removed but protamine is known to affect both platelet function and coagulation. There is uncertainty about how to best dose protamine to limit the negative effects from protamine without risking remaining heparin effect. A lot is known about how and to what extent cardiac surgery with the use of CPB affect the hemostasis in the patient, but there are still many uncertainties. The aims of this thesis were to examine how platelets are affected by CPB and protamine and to investigate if dosing of protamine had an impact on the risk of remaining or reappearing heparin after cardiac surgery. We also wanted to investigate whether sampling site matters when studying platelet function. In paper I, we found that protamine in vitro interacts with platelets by both a direct activating effect and by a secondary impairment of function when exposed to other activators. The impairment of platelet function from protamine could also be seen in vivo and is described in paper III. In paper III, we also conclude that, in contrast to prior studies, there was no increase in activation in platelets, nor net loss of platelets, during moderate CPB times. After CPB we found no impairment of platelet function compared with before surgery. In paper II, we found no differences in platelet aggregability between venous and arterial blood when measured with impedance aggregometry. Also, with flow cytometry most of our parameters showed no differences between venous and arterial blood. However, there were some differences. For example, the level of monocyte-platelet-aggregates was higher in venous- compared with arterial blood, which raises questions whether platelet function changes with oxygenation and flow conditions. In paper IV, we found a dose dependent risk of remaining heparin activity in the first postoperative period. We also found reappearance of heparin activity that was independent of the protamine dose in almost all our patients. We did not find any correlation between remaining or reappearing heparin activity and bleeding. In conclusion, this thesis describes that moderate CPB times do not have the severe impairment on platelet function earlier described in the literature. The thesis also increases the knowledge regarding how protamine affects platelet function and how dosing of protamine does and does not affect the risk of remaining and reappearing heparin activity. Finally, we conclude that in most cases platelet function can be studied in venous and arterial blood interchangeably, but there might be some differences in platelet function depending on whether they are in the venous our arterial system.
