Background: Many pathological processes can disrupt the integrity of the glomerular capillary wall and cause a massive leakage of protein, resulting in nephrotic syndrome (NS). Clinical parameters such as age, sex, renal function, presence of diabetes, and how NS is defined influence the spectrum of underlying diseases. In this study, we examine how these parameters interact.Methods: Age, sex, hem
BACKGROUND: Qigong includes training for body and mind, one method is Zhineng Qigong. Scientific literature on qigong for chronic low back pain (LBP) is sparse. This study aimed to investigate feasibility including evaluation of a Zhineng Qigong intervention for pain and other lumbar spine-related symptoms, disability, and health-related quality of life in patients with chronic LBP and/or leg pain
Popular Abstract in Swedish I Sverige och Norden har elproduktion traditionellt skett med huvudsakligen vattenkraft och kärnkraft. Detta håller dock på att förändras i takt med en allt större vindkraftsutbyggnad. Vindkraften skiljer sig i vissa avseenden från de traditionella produktionsslagen, ett av dessa är hur anslutningen till elnätet är utformad. Detta innebär att vindkraften, sedd från näteTraditionally the predominant generation has been large synchronous generators providing the system inertia. Nowadays when wind power and other non-synchronously connected units displaces this synchronous generation, the system inertia is reduced. Hence higher rate of change of frequency and larger frequency deviations are expected. This thesis deals with the impact on rate of change of frequency
Popular Abstract in Swedish Hur kan nattaktiva insekter se i mörker med fel sorts ögon? Majoriteten av alla dagaktiva insekter har en sorts facettöga som kallas appositionsöga. Appositionsögon är anpassade till ett liv med god tillgång på ljus ? nattaktiva djur har därför i princip alltid andra sorters ögon (superpositionsögon). Anledningen till att appositionsögon fungerar bäst på dagen är att dDue to our own preference for bright light, we tend to forget that many insects are active in very dim light. The reasons for nocturnal activity are most easily seen in tropical areas of the world, where animals face severe competition for food and nocturnal insects are able to forage in a climate of reduced competition and predation. Generally nocturnal insects possess superposition compound eye
Background: Accurate prehospital trauma triage is crucial for identifying critically injured patients and determining the level of care. In the prehospital setting, time and data are often scarce, limiting the complexity of triage models. The aim of this study was to assess whether, compared with logistic regression, the advanced machine learner XGBoost (eXtreme Gradient Boosting) is associated wi
Purpose: The quantitative accuracy of Nuclear Medicine images, acquired for both planar and SPECT studies, is influenced by the isotope-collimator combination as well as image corrections incorporated in the iterative reconstruction process. These factors can be investigated and optimised using Monte Carlo simulations. This study aimed to evaluate SPECT quantification accuracy for 123I with both t
Obesity associates with reduced life expectancy, type 2 diabetes, hypertension and cardiovascular disease, and is characterized by chronic inflammation. Phosphorylcholine (PC) is an epitope on oxidized low-density lipoprotein, dead cells and some microorganisms. Antibodies against PC (anti-PC) have anti-inflammatory properties. Here, we explored the role of anti-PC in hospitalized versus non-hospi
Future disasters or crises are difficult to predict and therefore hard to prepare for. However, while a specific event might not have happened, it can be simulated in an exercise. The evaluation of performance during such an exercise can provide important information regarding the current state of preparedness, and used to improve the response to future events. For this to happen, evaluation produ
Background and ObjectiveExperimental studies suggest that the balance between short and long β-amyloid (Aβ) species might modulate the toxic effects of Aβ in Alzheimer disease (AD), but clinical evidence is lacking. We studied whether Aβ38 levels in CSF relate to risk of AD dementia and cognitive decline.MethodsCSF Aβ38 levels were measured in 656 individuals across 2 clinical cohorts: the Swedish
This study deals with the desalination plant at the Eastern Mediterranean University (Cyprus) and its environmental impact. The reverse osmosis plant produces normally 42m3/hr potable water from 120m3/hr feed. The feed concentration reaches up to 36,000ppm TDS, while an approximate amount of 73.8m3/hr is led out from a pipe of 10inches diameter with a concentration of about 56,000ppm and the perme
Background: The implementation of screening programmes in Sweden during the mid-1990s increased the number of small node-negative breast cancers. In this era before staging by sentinel node biopsy, routine axillary dissection for staging of early breast cancer was questioned owing to the increased morbidity and lack of perceived benefit. The long-term risk of axillary recurrence when axillary stag
Experimental studies suggest that hepatocyte growth factor (HGF) and its transmembrane tyrosine kinase receptor, Met, in part also relying on Akt kinase activity, mediate radioresistance. We investigated the importance of these biomarkers for the risk of ipsilateral breast tumour recurrence (IBTR) after adjuvant radiotherapy (RT) in primary breast cancer. HGF, phosphorylated Met (pMet) and phospho
Purpose: Digital anthropomorphic breast phantoms have emerged in the past decade because of recent advances in 3D breast x-ray imaging techniques. Computer phantoms in the literature have incorporated power-law noise to represent glandular tissue and branching structures to represent linear components such as ducts. When power-law noise is added to those phantoms in one piece, the simulated fibrog
Objective: The long-term outcome after repair of complete atrioventricular septal defect in young infants is still not fully understood. The objective of this study was to evaluate data after repair for complete atrioventricular septal defect over a 25-year period to assess survival and identify risk factors for left atrioventricular valve–related reoperations. Methods: A total of 304 consecutive
Renewable diesel fuels have the potential to reduce net CO2 emissions, and simultaneously decrease particulate matter (PM) emissions. This study characterized engine-out PM emissions and PM-induced reactive oxygen species (ROS) formation potential. Emissions from a modern heavy-duty diesel engine without external aftertreatment devices, and fueled with petroleum diesel, hydrotreated vegetable oil
Introduction Children with appendicitis often present with complicated disease. The aim of this study was to describe the clinical management of pediatric appendicitis, and to report how disease severity and operative modality are associated with short- and long-term risks of adverse outcome. Materials and Methods A nationwide retrospective cohort study of all Swedish children (<18 years) diagnose
Introduction: Sudden cardiac death (SCD) and early onset cardiomyopathy (CM) in the young will always lead to suspicion of an underlying genetic disorder. Incited by the rapid advances in genetic testing for disease we have revisited families, which previously tested “gene-negative” for familial predominantly pediatric CM, in hopes of finding a causative gene variant. Methods: 10 different familie
Purpose: The study seeks to shed light on the generative principles of enterprising by examining the practices of enterprisers in six lifestyle enterprises in Sweden. It presents a fresh approach to the study of lifestyle enterprises, resolving a nuanced treatment of the concepts of capital and habitus as often drawn upon in studies using the social theory of Pierre Bourdieu. Design/methodology/ap
Background: Despite being the gold standard of research to determine effectiveness, randomised controlled trials (RCTs) often struggle with participant recruitment, engagement and retention. These issues may be exacerbated when recruiting vulnerable populations, such as participants with mental health issues. We aimed to update understanding of the scope of these problems in trials of health techn
BackgroundRisky sexual behavior is a public health challenge that significantly affects young people’s health and well-being in Sweden and throughout the world. Moreover, poor mental health, anxiety and depression among adolescents and young adults have increased in recent years. However, although hypothesized, the associations between general mental health and risky sexual behavior among young ad
