Purpose: The purpose of this work was to evaluate the visibility of simulated lesions in 2D digital mammography (DM) and breast tomosynthesis (BT) images of patients. Methods: Images of the same women were acquired on both a DM system (Mammomat Novation, Siemens Healthcare, Erlangen, Germany) and a BT prototype system adapted from the same type of DM system. Using the geometrical properties of the
Popular Abstract in Swedish Det har nu gått 20 år sedan ett utbrott av ledinflammation (arthrit), i Connecticut, USA, satte forskarna på spåret till den sjukdomsbild som vi idag kallar fästingöverförd borreliainfektion och det är snart 15 år sedan man lyckades isolera bakterien som orsakar sjukdomen, Borrelia burgdorferi. Symptomen på sjukdomen har visserligen varit kända sedan sekelskiftet men he
BACKGROUND: Tumor development requires angiogenesis, and antiangiogenesis has been introduced in the treatment of cancer patients; however, how the cardiovascular phenotype correlates with cancer risk remains ill-defined. Here, we hypothesized that vasoactive peptides previously implicated in angiogenesis regulation predict long-term cancer risk.METHODS: We measured midregional proatrial natriuret
BACKGROUND: The incidence of distal radius fracture has increased substantially during the last 50 years according to several studies that estimated the overall incidence in various general populations. The incidence of fracture classified according to severity has not been well documented. The aim of this population-based study was to estimate the overall and type-specific incidence rates of dist
ABSTRACT: Study Design. Prospective randomized controlled study.Objective. To compare the outcome of indirect decompression by means of the X-Stop implant to conventional decompression in patients with neurogenic intermittent claudication due to lumbar spinal stenosis.Summary of Background Data. Decompression is the golden standard for lumbar spinal stenosis nowadays but afflicted with complicatio
Background: The link between colorectal cancer (CRC) and type 2 diabetes mellitus (T2D) has been extensively studied. Although it is commonly accepted that T2D is a risk factor for CRC, the underlying mechanisms are still poorly understood. Research Design and Methods:Given that the genetic background contributes to both traits, it is conceivable that genetic variants associated with T2D may also
Abstract Objective. The aim of this study was to validate externally the Swedish Lund-Malmö revised creatinine-based glomerular filtration rate (GFR) equations (LM Revised) in a Swedish cohort in comparison with the North American Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology (CKD-EPI) equations. Material and methods. The study included 1397 examinations [med
The thesis investigates how a norm-critical perspective on learning can impact the architectural design, and the aim is not to challenge the school as a form but to mediate a more supportive learning environment. The norm-critical, feminist and public pedagogy highlights the necessity of change towards collective learning with the individual in mind that includes introvert and extrovert personalit
Overheating in buildings is becoming a major concern and cause for various health issues. Existing research and previous studies on the issue were examined to acquire relevant information about the definition of overheating, its possible causes, and the heath impacts it could have on human health. The review included data on the current status of thermal comfort and overheating regulations in Swed
Produktion av en nanotrådssolcell För att ta itu med miljöpåverkan från växthusgaser krävs en övergång till förnyelsebara energikällor. Ett exempel på en sådan källa är nanotrådssolceller. I mitt examensarbete har jag undersökt hur nanotrådar kan arrangeras på sådant sätt som krävs för att kunna omvandla solljuset till elektricitet. Global uppvärmning är ett hot som till stor del orsakas av utslThe demand for cheaper and more efficient solar cells is high. One way to decrease cost of material, while maintaining a high degree of efficiency, is to take advantage of nanomaterials. A thin film containing pn-junction nanowires can convert light with an efficiency comparable to traditional planar cells, while using a fraction of the material, and thus reduce costs.

A detailed flammability evaluation of different materials used in the nuclear power industry is presented as an example of how important are physical observation and detailed analysis in the interpretation of test data. The objective is to provide different criteria that could allow the use of standard test data in fire modeling. So far most fire test data has only been used as an element for rank
Background: Fibroblast growth factor 23 (FGF23) is the earliest marker of disturbed mineral metabolism as renal function decreases. Its serum levels are associated with mortality in dialysis patients, persons with chronic kidney disease (CKD) and prevalent cardiovascular disease (CVD), and it is associated with atherosclerosis, endothelial dysfunction and left ventricular hypertrophy in the genera
Background: Metabolic syndrome (MetS) remains a controversial entity. Specific clusters of MetS components - rather than MetS per se - are associated with accelerated arterial ageing and with cardiovascular (CV) events. To investigate whether the distribution of clusters of MetS components differed cross-culturally, we studied 34,821 subjects from 12 cohorts from 10 European countries and one coho
Background: Frontotemporal dementia (FTD) is recognised as a clinically and morphologically heterogeneous group of interrelated neurodegenerative conditions. One of the subtypes within this disease spectrum is the behavioural variant FTD (bvFTD). This is known to be a varied disorder with a mixture of tau-positive and tau-negative underlying pathologies. The other subtypes include semantic dementi
OBJECTIVE Patients with latent autoimmune diabetes in adults (LADA) express autoantibodies against the 65-kDa isoform of GAD (GADA). Intervention with recombinant human GAD65 formulated with aluminium hydroxide (GAD-alum) given twice subcutaneously to LADA patients at intervals of 4 weeks was safe and did not compromise beta-cell function in a Phase II clinical trial. GADA affinity has been shown
Context Approximately 10% of women with invasive epithelial ovarian cancer (EOC) carry deleterious germline mutations in BRCA1 or BRCA2. A recent article suggested that BRCA2-related EOC was associated with an improved prognosis, but the effect of BRCA1 remains unclear. Objective To characterize the survival of BRCA carriers with EOC compared with noncarriers and to determine whether BRCA1 and BRC
Objective To investigate the possible association of the BANK1 gene with genetic susceptibility to systemic sclerosis (SSc) and its subphenotypes. Methods A large multicentre case-control association study including 2380 patients with SSc and 3270 healthy controls from six independent case-control sets of Caucasian ancestry ( American, Spanish, Dutch, German, Swedish and Italian) was conducted. Th
Background: Currently available biomarkers for the early tissue process leading to joint damage in rheumatoid arthritis are insufficient and lack prognostic accuracy, possibly a result of variable activity of the disease over time. This study represents a novel approach to detect an altered activity of the disease process detected as increasing serum-COMP levels over a short time and whether this
To identify prognostic factors after hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT). We retrospectively reviewed the combined experience at Toronto General Hospital and Hospital Vall d'Hebron managing HCC recurrence after LT (n = 121) between 2000 and 2012. We analyzed prognostic factors by uni- and multi-variate analysis. Median follow-up from LT was 29.5 (range 2-129.
Background: Ultrafiltration (UF) insufficiency in peritoneal dialysis (PD) often leads to transfer to hemodialysis. Therefore, strategies to prolong time on therapy are needed. The use of a combined crystalloid and colloid solution, also called bimodal PD, can help improve UF. Methods: We propose a method for reconstituting bimodal solutions. Three bimodal PD solutions, with respectively 100 ml (s
