Objective: The purpose of this study was to describe procedural changes in hospital incident investigations and show the consequences of these changes over time. Methods: A two-stage method was used. First component of the study was a content analysis of 87 incident investigations conducted 1995-2014 by the regulatory authority after adverse events in a Swedish university hospital. Second compone
Animals living in environments of different quality will have different expectations of their future reproductive success and survival. This may affect the individual's risk-taking behaviour as manifest in the cost of predation. We investigated the foraging behaviour of starlings, Sturnus vulgaris, when perceived predation risk varied between patches. Short-term food availability varied between tr
Early hypocalcemia after thyroid surgery has frequently been reported, whereas data regarding long-term effects on calcium homeostasis are scarce. We have previously studied patients after hemithyroidectomy with an oral calcium load test and found normal parathyroid hormone (PTH) suppression. However, the 1,25-dihydroxyvitamin D concentration was decreased and the phosphate concentration increased
Recent numerical simulations have shown long-lived axisymmetric sub- and super-Keplerian flows in protoplanetary disks. These zonal flows are found in local as well as global simulations of disks unstable to the magnetorotational instability. This paper covers our study of the strength and lifetime of zonal flows and the resulting long-lived gas over- and underdensities as functions of the azimuth
We investigated changes of postural responses to repeated bipolar galvanic vestibular stimulation on 5 consecutive days and once again after 3 months. Subjects consisted of 21 healthy volunteers. Except for the first day did the induced torque variance in response to galvanic vestibular stimulation not decrease {within} each test session, but there was a major reduction {from day to day} (p< 0.001
BACKGROUND: The aim was to investigate the effect of calcium in organ preservation solutions with respect to 36-hour preservation of vascular smooth muscle function and endothelium-dependent relaxation. METHODS: The infrarenal aortas of 60 Sprague-Dawley rats were studied in organ baths as fresh controls and after 36 hours of cold (4 degrees C) storage in different preservation solutions with and
Acute lymphoblastic leukaemia (ALL) is the most common childhood malignancy. The survival rate in the Scandinavian countries is now around 85 %. ALL patients treated with cranial radiotherapy (CRT) are at risk for growth hormone deficiency (GHD), but little is known about other pituitary insufficiencies, e.g. ACTH. Adult ALL patients (median age at study 25 years), treated with 24 Gy (18-30) of CR
Background: The evidence about nitrosamines and heme iron intake and cancer risk is limited, despite the biologic plausibility of the hypothesis that these factors might increase cancer risk. We investigated the association between dietary nitrosamines and heme iron and the risk of prostate cancer among participants of European Prospective Investigation into Cancer and Nutrition (EPIC). Methods: D
We compare different preference restrictions that ensure the existence of a stable roommate matching. Some of these restrictions are generalized to allow for indifferences as well as incomplete preference lists, in the sense that an agent may prefer remaining single to matching with some agents. We also introduce a new type of cycles and in greater detail investigate the domain of preferences that
Perinatal asphyxia with hypoxic ischemic encephalopathy (HIE) is the most important cause of perinatal mortality and cerebral palsy (CP) in infants born at term. The aim of the thesis was to investigate epidemiology of perinatal asphyxia, and to investigate early clinical neurological symptoms after perinatal asphyxia in relation to cerebral glucose metabolism (CMRgl) measured by 18-FDG-PET, neuro
