Numerous Neoproterozoic mafic dykes, referred to as the Dashigou swarm, are identified in the central and southeastern parts of the North China craton (NCC). They are 305-010 degrees trending dykes, with widths of similar to 10-100 m and exposed lengths of several to >10 km. Precise U-Pb isotope dilution thermal ionization mass spectrometry (ID-TIMS) measurements on baddeleyite grains separated fr

Barsebäcks kärnkraftverk driftsattes 1975 och den första reaktorn togs ur drift 1999 och den andra 2005. Nedmontering och rivning av kärnkraftverket har inletts och processen beräknas vara klar på 2030-talet. Syftet med detta examensarbete är att kartlägga eventuell radioaktiv kontamination i området runt Barsebäcksverket. Mitt mål är att ta fram en metod för att särskilja bakgrundsstrålning från Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. The aim of this thesis was to identify and quantify residual anthropogenic radioacti

BACKGROUND: HYPO-RT-PC is a phase 3 trial comparing ultra-hypofractionated and conventionally fractionated radiotherapy in intermediate-to-high-risk localised prostate cancer. This 10-year update reports long-term efficacy and toxicity outcomes.METHODS: In this open-label, randomised, phase 3, non-inferiority trial done in ten centres in Sweden and two in Denmark, we recruited men aged 75 years or

Background Breast cancer is the most frequently diagnosed cancer in women. Survival is generally considered favourable, yet some patients remain at risk of early death. We aimed to assess whether comprehensive whole-genome sequencing (WGS) linked to mortality data could add prognostic value to existing clinical measures and identify patients who might respond to targeted therapeutics. Methods In t

Acute leukemia affects individuals of all ages and encompasses a heterogeneous group of malignancies driven by genetic alterations that give rise to leukemia stem cells (LSCs), which sustain self-renewal and drive the expansion of abnormal cells. Based on how these alterations affect maturation, acute leukemia is classified into acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL).

Pain, use of painkillers and alcohol are highly prevalent in the general population. Aims of the study were to describe differences in pain, alcohol consumption and use of painkillers among two 60 year old birth cohorts stratified by gender. Participants were recruited from the Skåne centre of The Swedish National study on Aging and Care, a multicentre, prospective, longitudinal study. The sample

Abstract Background: Advanced paediatric surgery is increasingly centralised in Sweden in order to improve treatment outcomes and reduce surgical risks. However, the overall need for surgery in the paediatric population has not been estimated, and the association between geographic access to surgical facilities and timely treatment for common surgical conditions in children is largely unknown.

Hjärtsvikt betecknar ett syndrom som innebär att hjärtat har otillräcklig förmåga att försörja kroppen med blod. Detta kan antingen bero på att hjärtat inte kan fyllas med eller stöta ut tillräckligt med mängd blod. Patienter med hjärtsvikt har i allmänhet hög dödlighet, detta trots att stora framsteg har gjorts avseende behandlingen av hjärtsvikt, speciellt sedan 1980-talet. Femårsöverlevnaden föIntroduction: Despite major advances, the incidence rate and mortality of heart failure (HF) remains high, with a five-year survival of approximately 50%. At the time of inception of this thesis the familial risks of HF, including the aspects of mortality, were largely underdetermined. This thesis is composed of four papers with the main aims as follows:To determine the risk of hospitalization of

Background: Survivors of childhood cancer are at increased risk for a wide range of late effects. However, no large population-based studies have included the whole range of somatic diagnoses including subgroup diagnoses and all main types of childhood cancers. Therefore, we aimed to provide the most detailed overview of the long-term risk of hospitalisation in survivors of childhood cancer. Metho

IMPORTANCE The clinical management of BRCA1 and BRCA2 mutation carriers requires accurate, prospective cancer risk estimates. OBJECTIVES To estimate age-specific risks of breast, ovarian, and contralateral breast cancer for mutation carriers and to evaluate risk modification by family cancer history and mutation location. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study of 6036 BRCA1 and

Barnobesitas är sedan flera år ett ökat hälsoproblem bland barn. Obesitas vid 4 års ålder ger en kraftigt ökad risk för obesitas senare i livet. Att förebygga uppkomst och utveckling av obesitas är en långsiktig investering för framtiden. Idag finns ingen evidensbaserad metod för vägledning inom barnhälsovården för att främja hälsosamma levnadsvanor och förebygga obesitas hos förskolebarn. Det övePrevention of childhood obesity with its effects on children’s mental and physical health and well-being is an international public health priority and is suggested to be effective when started early. As Child Health Services lack an evidence-based model, there is the need for development of a low-intensive health promotion model that is feasible and cost-effective in preventing obesity in prescho

Background Influenza and other respiratory viruses promote Streptococcus pneumoniae proliferation in the upper respiratory tract. We sought to investigate for what we believe is the first time, the effect of intranasal live attenuated influenza vaccine (LAIV) on nasopharyngeal S pneumoniae density in a low-income to middle-income country population with high pneumococcal carriage rates. Methods I

Background and objectives: Neuroinflammation is implicated in the development and maintenance of persistent pain states, but there is limited data linking cerebrospinal fluid (CSF) inflammatory mediators with neurophysiological pain processes in humans. Study I aimed to investigate whether there are coherent changes in CSF inflammation associated with central sensitization (CS), and to evaluate po

Ultrasonic motors (USMs) have been extensively studied for three decades, due to their attractive features, such as high torque at low speed, simple structure, and precise positioning capability. However, since USMs are driven by the friction force between the rotor and the stator in most cases, they inherently possess the friction loss and the wear of contact materials, which cause their low effi

Importance: Long-term follow-up after transcatheter aortic valve replacement (TAVR) is of interest given that longitudinal data on mortality and durability of transcatheter heart valves are limited. The REPRISE III (Repositionable Percutaneous Replacement of Stenotic Aortic Valve Through Implantation of Lotus Valve System-Randomized Clinical Evaluation) randomized clinical trial compared the mecha

This study aims to investigate and disentangle the impact of land use and climate variability on the Baltic Sea coastal zone from a millennial perspective. To assess the environmental status of the coastal zone we make use of siliceous microfossils (mainly diatoms), stable nitrogen and carbon isotopes, organic carbon accumulation rates, and lithological changes analyzed in a sediment core collecte

Importance: Recent studies have questioned the presumed low-risk status of patients with asymptomatic nonsevere aortic stenosis (AS). Whether annual N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements are useful for risk assessment is unknown. Objective: To assess the association of annual NT-proBNP measurements with clinical outcomes in patients with nonsevere AS. Design, Setting, a

IMPORTANCE: Prostate-specific antigen (PSA) screening has potential to reduce prostate cancer mortality but frequently detects prostate cancer that is not clinically important.OBJECTIVE: To describe rates of low-grade (grade group 1) and high-grade (grade groups 2-5) prostate cancer identified among men invited to participate in a prostate cancer screening protocol consisting of a PSA test, a 4-ka
