Background: Postoperative nausea and vomiting (PONV) is common after general anaesthesia, and corticosteroids are used in many protocols for enhanced recovery after surgery (ERAS). However, surgical techniques are developing, and ERAS protocols need to be reevaluated from time to time. Patients and method: In this study, we compared the effects of oral vs. parenteral corticosteroid administration
Popular Abstract in Swedish I denna avhandling presenteras en ny typ av röntgenkälla baserad på ett laser-producerat plasma. Röntgenstrålning alstras genom att fokusera laserpulser på ett strålmål. Energin i de enskilda laserpulserna blott är cirka 150 mJ, men tack vare den extremt korta pulstiden 100 fs (10E-13 s), blir laserns toppeffekt mer än 1 TW (10E12 W). Den extremt intensiva laserstrålninA laser-produced plasma was generated by focusing 100 fs laser pulses, with an energy of 150 mJ, onto metal targets. The laser intensity was expected to reach 10E17 W/cm2. Radiation was emitted from the created plasma, with photon energies extending up to the MeV regime. The laser-based X-ray source was optimised, with the purpose of making it a realistic source of hard X-rays (>10 keV). Dedicated
This thesis deals primarily with the production of written texts by adults with reading and writing difficulties. Their writing is analysed from three different aspects: error analysis, non-error-oriented text analysis and analysis of the production process. These studies are based on data from on-line recordings of writing. The main question is how the written language production of adults with r
This article presents the analysis of a large survey on file-sharing that was conducted in April 2011 with over 75,000 respondents from all over the world. The study, also known as The Research Bay, due to that it was conducted in collaboration with the infamous BitTorrent site The Pirate Bay, by the Cybernorms research group. The aim of the online study of The Pirate Bay community has been to des
ABSTRACT: BACKGROUND: The study was designed to investigate the effect of different measuring methodologies on the estimation of P wave duration. The recording length required to ensure reproducibility in unfiltered, signal-averaged P wave analysis was also investigated. An algorithm for automated classification was designed and its reproducibility of manual P wave morphology classification invest
In Sweden a new red list was issued 2000, but there is no published list of the most important areas for biodiversity preservation. I use woodliving and red-listed beetles as indicators of “hot-spots” for biodiversity preservation, since these insects constitute a large proportion of the red-listed forest living species in Sweden. Based on museum and many large private collections of beetles from
Before, during, and after cardiac intervention, there is occasionally a need for circulatory support because of hemodynamic deterioration. For this purpose, a new minimally invasive cardiac assist device has been developed, and an early prototype has been studied in a bench test and in three pigs. The pump is a catheter system with a distal motor driven propeller (0-15,000 rpm) surrounded by a cag
Background: Spontaneous bacterial peritonitis (SBP), which has been reported to be present in 10-30% of patients with cirrhotic ascites, may easily be overlooked. An important aim of our study was to determine whether there are any clinical signs which, in clinical practice, may predict or exclude SBP. Methods: We studied 133 patients with cirrhotic ascites from medical units at nine Swedish unive
Abstract in French L’étude de l’effet d’amorçage syntaxique (syntactic priming) permet d’examiner la relation (potentielle) entre input et output dans l’interaction. On observe un effet d’amorçage lorsque la présentation d’un item (l’amorce) facilite le traitement ultérieur d’un item similaire (la cible). L’amorçage syntaxique ou structurel est un phénomène de réutilisation de la structure syntaxi
Introduction: Lactate concentration is known to be a strong predictor of mortality, but is not included in any of the major intensive care scorings systems such as the Simplified Acute Physiology Score (SAPS 3). The objective of this study was to investigate the prognostic value of lactate concentration when combined with SAPS 3. Materials and methods: In the period of 2008 to June 2017 the genera
Background: The WHO and the World Bank ask countries to report the national volume of surgery. This report describes these data for Sweden, a high-income country. Methods: In an 8-year population-based observational cohort study, all inpatient and outpatient care in the public and private sectors was detected in the Swedish National Patient Register and screened for the occurrence of surgery. The
Mental disorders are associated with premature mortality, and the magnitudes of risk have commonly been estimated using hospital data. However, psychiatric patients who are hospitalized have more severe illness and do not adequately represent mental disorders in the general population. We conducted a national cohort study using outpatient and inpatient diagnoses for the entire Swedish adult popula
Decrease of the human brain temperature was induced by intranasal cooling. The main purpose of this study was to compare the two magnetic resonance methods for monitoring brain temperature changes during cooling: phase-difference and magnetic resonance spectroscopic imaging (MRSI) with high spatial resolution. Ten healthy volunteers were measured. Selective brain cooling was performed through nasa
Background: A significant subset of prostate cancer (PC) patients with a castration-resistant form of the disease (CRPC) show primary resistance to androgen receptor (AR)-targeting drugs developed against CRPC. As one explanation could be the expression of constitutively active androgen receptor splice variants (AR-Vs), our current objectives were to study AR-Vs and other AR aberrations to better
The present study aimed to estimate possible differences in upper body muscular load between male and female house painters performing identical work tasks. Sex-related differences in muscular load may help explain why women, in general, have more musculoskeletal complaints than men. In a laboratory setting, 16 male and 16 female house painters performed nine standardised work tasks common to hous
Background. Decompressive craniectomy (DC) is an option for the treatment of increased intracranial pressure resulting from an acute neurological insult, including insults caused by trauma. When the brain swelling has receded, the skull is reconstructed with a wide choice of materials, each with its own advantages and disadvantages in terms of cost, cosmetic appearance, biocompatibility, implant s
There is a growing gap between tourism's rapidly growing greenhouse gas emissions and the sector's 'aspirational' emission reduction targets as well as the international policy consensus to reduce emissions from this and all other sectors of the economy. The transport component is the largest GHG contributor to the global tourism system. In the absence of supranational policy agreements to curb em
The following essays checks whether the Swedish stock market (represented by OMXS30) supports the weak efficiency of the EMH by observing whether the stocks contain a unit root and whether one can use trading strategies to create abnormal profits. The AR(1) model of the stock prices have a unit root coefficient very close to 1, thus they are trend stationary but have a very long memory. This model
“Men from March, women from Venus” is a bachelor thesis where the Swedish populations consumption habits of the product groups clothes, underwear and shoes are individually examined through statistical analysis. The aim of the thesis is to examine if any differences between male and female consumption of those product groups can be determined for the first year of the financial crisis. This is det
