This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. They can give a better understanding of the processes
Given the current societal and political developments in Germany, the visibility and integration of-marginalized is essential to ensure their inclusion in mainstream society. One way of encouraging-contact between majority and marginalized groups is through building social networks, of which-informal and nonformal educational activities play an important part. This thesis examines the-experience o
BACKGROUND: Accurate risk stratification in older adults presenting to the emergency department (ED) is essential but challenging due to atypical presentations and age-related physiological changes. While vital signs are central to triage, their predictive value for short-term mortality in this population remains unclear. This study aimed to explore the association between initial vital signs and
The transition from animal-based to plant-based proteins is rapidly increasing because of different concerns about meat consumption, some being the nutritional and environmental effects of meat consumption. During this transition, there needs to be a holistic approach to assessing plant-based food. This master thesis is focused on investigating the nutritional and environmental impact of three pla
Background The two main functional goals of postural control are postural stability (balance) and postural orientation. Postural orientation is the ability to maintain alignment between body segments and the environment during a static or dynamic activity. Nae et al. have evaluated the measurement properties of a clinical test battery for assessing postural orientation errors (POEs) in patients wi
Objective: Transcatheter valve-in-valve implantation has emerged as an option, in addition to reoperative surgical aortic valve replacement, to treat failed biologic heart valve substitutes. However, the clinical experience with this approach is still limited. We report the comprehensive experience of transcatheter valve-in-valve implantation in the Nordic countries from May 2008 to January 2012.
Purpose: To assess the additional value of subtraction ictal single-photon emission computed tomography (SPECT) coregistered to MRI (SISCOM) for localization of the epileptogenic zone in patients with drug-resistant epilepsy scheduled for invasive video-EEG (VEEG) before epilepsy surgery by a descriptive study from clinical practice. Methods: Forty-nine consecutive epilepsy patients between Januar
Background: The aim of this study was to examine in elderly men a relationship between depressive symptoms, peripheral vascular disease and cerebral blood flow (CBF). Methods: Population-based cohort study started with an examination of 809 men at age 55, followed by the first (age 68ys) and second follow up (age 82ys). 128 survivors were examined at age 82 with Tc-99m-HMPAO-SPECT to estimate CBF,
Forests form the backbone of the European terrestrial carbon sink (State Forest Service & Ministry of Environment, 2018). As the European Union (EU) strives to become climate neutral by 2050, forests are accounted for the natural carbon absorption mechanism (European Commission, n.d.). Currently, the European net land carbon sink is decreasing largely due to forest ageing (Pilli et al., 2022),
Popular Abstract in Swedish Populärvetenskaplig sammanfattning på svenska Abort är ett av de vanligaste kriurgiska ingreppen i Sverige. 1989 var aborttalet för hela landet 21.5 per 1000 kvinnor i åldern 15-24 år. Storstäderna Stockholm, Göteborg och Malmö har i många år haft det högsta aborttalen, vilka var för dessa 1989 28.4, 27.0 respektive 27.8. De aktuella studierna omfattar de 1466 kvinnorIn Sweden between 32-38,000 women annually elect to terminate pregnancy by means of induced abortion, though their reasons are still not well understood. The purpose of these studies, carried out at the Department of Obstetrics and gynecology and of Community Medicine at University Hospital, Malmö, was to elucidate the incidence of induced abortion in an urban population, with special emphasis on
Popular Abstract in Swedish Denna avhandling är en del av en prospektiv, longitudinell studie, som avser att studera sambandet mellan psykosociala faktorer och debuten och förloppet av barndiabetes. Diabetes är en av de vanligaste kroniska sjukdomarna hos barn i Sverige och antalet insjuknade ökar. Tillsammans med Finland har Sverige en av de högsta förekomsterna av barndiabetes i världen. SjukdomThis thesis is a part of a prospective multi-centre study concerning psychosocial aspects of importance for the onset and course of insulin-dependent diabetes mellitus (IDDM). The investigated population was all children with onset of IDDM in the participating clinics during 1988 and 1989. Of 79 diseased children, 67 participated in the study. To each child a healthy control child was chosen, 61 a
Objective: Studies of the importance of perinatal factors for the development of irritable bowel syndrome (IBS) are sparse. We conducted a large national cohort study to examine perinatal and familial risk factors for IBS. Material and methods: A national cohort of 1,963,685 persons who were born in Sweden in 1973–1992 (identified from the Swedish Birth Registry) were followed up for adult (18 yea
Objective: The authors sought to determine whether pregnancy is an intrinsic motivator for cessation of drug abuse. Method: The authors conducted prospective cohort, corelative, co-spouse, and within-person analyses of registration for drug abuse during pregnancy among Swedish women born between 1980 and 1990 who gave birth between ages 20 and 35 (N=149,512). Drug abuse was assessed from medical,
Background: The solute carrier family 30 member 8 gene (SLC30A8) encodes a zinc transporter in the pancreatic beta cells and the major C-allele of a missense variant (rs13266634; C/T; R325W) in SLC30A8 is associated with an increased risk of type 2 diabetes (T2D). We hypothesized that the association between zinc intake and T2D may be modified by the SLC30A8 genotype. Results: We carried out a pro
Satellite remote sensing of plant phenology provides an important indicator of climate change. However, start of the growing season (SOS) estimates in Northern Hemisphere boreal forest areas are known to be challenged by the presence of seasonal snow cover and limited seasonality in the greenness signal for evergreen needleleaf forests, which can both bias and impede trend estimates of SOS. The ne
Background: There are currently no methods in clinical use that can detect early systemic dissemination of urothelial tumor cells. Objective: To evaluate measurement of circulating tumor cells (CTCs) as a biomarker for disseminated disease in patients with advanced bladder cancer. Design, setting, and participants: Between March 2013 and October 2015, 88 patients were prospectively included in the
Context: After an anterior cruciate ligament (ACL) injury, a majority of patients have a traumatic bone marrow lesion (BML, or bone bruise). The clinical relevance of posttraumatic lesions remains unclear. Objective: To explore the cross-sectional associations between traumatic BML volume and self-reported knee pain and symptoms among individuals within 4 weeks of ACL injury. Design: Cross-section
The adrenal-derived hormones dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are the most abundant circulating hormones and their levels decline substantially with age. DHEAS is considered an inactive precursor, which is converted into androgens and estrogens via local metabolism in peripheral target tissues. The predictive value of serum DHEAS for fracture risk is unknown. The aim of this s
BACKGROUND: Autonomic disorders of the cardiovascular system, such as orthostatic hypotension and elevated resting heart rate, predict mortality and cardiovascular events in the population. Low-energy-fractures constitute a substantial clinical problem that may represent an additional risk related to such autonomic dysfunction.AIMS: To test the association between orthostatic hypotension, resting
