Atherosclerotic cardiovascular disease is a major problem despite the availability of drugs that influence major risk factors. New treatments are needed, and there is growing interest in therapies that may have multiple actions. Thyroid hormone modulates several cardiovascular risk factors and delays atherosclerosis progression in humans. However, use of(More)
OBJECTIVES To find out how patients perceive their health-related quality of life after they have been treated in an intensive care unit and whether preexisting disease influenced their perception. DESIGN : Follow-up, quantitative, dual-site study. SETTING Combined medical and surgical intensive care units of one university and one general hospital in(More)
Laser Doppler perfusion imaging (LDPI), is a further development in laser Doppler flowmetry (LDF). Its advantage is that it enables assessment of microvascular blood flow in a predefined skin area rather than, as for LDF, in one place. In many ways this method seems to be more promising than LDF in the assessment of burn wounds. However, several(More)
Oxygen treatment has been a cornerstone of acute medical care for numerous pathological states. Initially, this was supported by the assumed need to avoid hypoxaemia and tissue hypoxia. Most acute treatment algorithms, therefore, recommended the liberal use of a high fraction of inspired oxygen, often without first confirming the presence of a hypoxic(More)
Hyperoxia causes vasoconstriction in most tissues, by mechanisms that are not fully understood. We investigated microvascular effects of breathing 100% oxygen in healthy volunteers, using iontophoresis to deliver acetylcholine (ACh) and sodium nitroprusside (SNP). Aspirin and vitamin C were used to test for involvement of prostaglandins and radical oxygen(More)
BACKGROUND The use of objective methods for assessment of burns is limited. Laser Speckle Contrast Imaging (LSCI) is a non-invasive technique for instant measurement of tissue perfusion, making it potentially valuable for early prediction of burn wound outcome. AIM To evaluate the influence of technical factors on perfusion and to measure perfusion in(More)
Hypocapnia is known to decrease blood flow and tissue oxygen tension in the brain and the splanchnic organs, but there are few and contradictory results in skeletal muscle. The aim of the present study was to investigate the effect of hypocapnia on microcirculatory blood flow, local skeletal muscle PO2 (PtO2) and pH (pHt). Blood flow was measured using(More)
This study was done at the Linköping University Hospital, Sweden, to assess the quality of care given to patients undergoing outpatient anaesthesia. A questionnaire was given to all adult patients (> 15 years old) immediately on admission to the outpatients' surgical ward and the patients were asked to answer all the questions, if necessary with the help of(More)
OBJECTIVE To compare three International Classification of Diseases code abstraction strategies that have previously been reported to mirror severe sepsis by examining retrospective Swedish national data from 1987 to 2005 inclusive. DESIGN Retrospective cohort study. SETTING Swedish hospital discharge database. PATIENTS All hospital admissions during(More)
BACKGROUND/AIMS Many clinical conditions that affect the microcirculation of the skin are still diagnosed and followed up by observational methods alone in spite of the fact that non-invasive, more user-independent and objective methods are available today. Limited portability, high cost, lack of robustness and non-specificity of findings are among the(More)
