Time trends in incidence, causes of death, and prognosis of cancer of unknown primary (CUP) could provide important clues for occult primary sites and thus result in effective organ-specific treatment, although such studies are seldom reported. We aimed at examining time trends in percentage and incidence rates, causes of death, and survival of CUP. A total of 50 545 patients with CUP were identif
AIM/HYPOTHESIS: Individuals at risk of developing type 2 diabetes show a progressive decline in insulin secretion and increased insulin resistance over time. However, inability of the beta cells to compensate for the increased insulin resistance represents a key defect leading to overt type 2 diabetes. The aims of the present study were to replicate the association between genetic variants of the
Registry based cancer incidence and mortality data are widely used for etiologic research, cancer control and health care monitoring and planning. The complete coverage of all cases is the key criteria of data quality but it is difficult to assess because the alternative sources of data may be flawed. The aim of this study was to examine, at a nationwide level, the completeness of the Swedish Canc
The purpose of this paper is to study the transfer of knowledge between preparedness activities and emergency response at the municipal level to improve emergency response. Design/methodology/approach - A case study was carried out in the municipality of Ljungby using prewritten questions to analyse the collected empirical material. This material consisted of both municipality documents and
Precision laser frequency stabilization is an important part of modern optical metrology, with applications ranging from atomic clocks to fundamental tests of physics. However, the frequency stability of the ultrastable cavities used in these experiments is fundamentally limited by thermal noise in the mirrors of the cavity. The thermal noise causes the atoms that form the mirrors to move randomly
The accumulation of amyloid fibrils from the protein 𝛼-synuclein is a pathological hallmark of Parkinson´s disease. 𝛼-synuclein is a highly polar protein with a remarkable primary structure that can be divided into three regions: the slightly basic N-terminal region, a central hydrophobic region, and a highly acidic C-terminal tail. The C-terminal tail is of specific focus in this thesis. A chan
The discovery of ferroelectricity in nanoscale hafnia-based oxide films has spurred interest in understanding their emergent properties. Investigation focuses on the size-dependent polarization behavior, which is sensitive to content and movement of oxygen vacancies. Though polarization switching and electrochemical reactions is shown to co-occur, their relationship remains unclear. This study emp
There has been a long-standing interest in targeting the type 1 insulin-like growth factor receptor (IGF-1R) signaling system in breast cancer due to its key role in neoplastic proliferation and survival. However, no IGF-1R targeting agent has shown substantial clinical benefit in controlled phase 3 trials, and no biomarker has been shown to have clinical utility in the prediction of benefit from
The age-standardized prevalence of Parkinson's disease (PD) has increased substantially over the years and is expected to increase further. This emphasizes the need to identify modifiable risk factors of PD, which could form a logical entry point for the prevention of PD. The World Health Organization (WHO) has recommended reducing exposure to specific environmental factors that have been reported
Background: Road-traffic noise may influence the development of cardiovascular events such as stroke and myocardial infarction, but etiological mechanisms remain unclear. This study aimed to assess the relationship between long-term road-traffic noise exposure and coronary atherosclerosis in Sweden. Methods: In the Swedish CArdioPulmonary bioImage Study (SCAPIS) cohort, including 30,154 subjects a
Background: Poor oral health is associated with several non-communicable diseases including cardiovascular disease. There are also well-known associations between lifestyle habits, cardiovascular disease, and oral health. In Europe, SCORE2 is a recommended instrument for assessing an individual's risk of a cardiovascular event within 10 years. However, no previous studies have examined the associa
Terahertz pulses generated by two-color laser plasmas have reported peak field strengths exceeding MV/cm, and when illuminating metal nanotips, the near-field enhancement at the tip apex should result in extremely high bunch charges and electron energies via sub-cycle cold-field emission. Here, electron emission from tungsten nanotips driven by THz pulses generated by a long filament air-plasma is
Background: Multimorbidity, i.e. two or more non-communicable diseases (NCDs), has been associated with venous thromboembolism (VTE), but whether multimorbidity is a predictor for incident VTE is unknown. Aims: To examine the associations between multimorbidity and its severity with risk of incident VTE, and examine the association between nine different disease clusters and incident VTE. Methods:
Whether monetary incentives to change behavior work and how they should be structured are fundamental economic questions. We overcome typical data limitations in a large-scale field experiment on vaccination (N = 5,324) with a unique combination of administrative and survey data. We find that guaranteed incentives of $20 increase uptake by 13 percentage points in the short run and 9 in the long ru
This study investigated the molecular basis of disease severity in acute pyelonephritis (APN), a common and potentially life-threatening bacterial infection. Two cohorts of infants with febrile urinary tract infection were included. Renal involvement was defined by DMSA scans and molecular disease determinants by gene expression analysis and proteomic screens, at diagnosis and after 6 mo. Innate i
Objective To investigate the relation between preterm birth (gestational age <37 weeks) and risk of CKD from childhood into mid-adulthood. Design National cohort study. Setting Sweden. Participants 4 186 615 singleton live births in Sweden during 1973-2014. Exposures Gestational age at birth, identified from nationwide birth records in the Swedish birth registry. Main outcome measures CKD, identif
In the passive solar water heater, temperature stratification is a valuable thermodynamic parameter for horizontal water storage tanks. This investigation aims to optimize the deflector and numerically study the effects of various deflector lengths and materials on temperature stratification of a horizontal water storage tank during natural convection. Firstly, comparative thermal performances of
With the urgent demand for ultralow-temperature refrigerators worldwide, the operation reliability and stability of the refrigeration system becomes greatly crucial. In this study, a -80 oC ultralow-temperature cascade refrigeration system (CRS) is developed. From aspects of global warming potential (GWP) and ozone depletion potential (ODP), the environmentally friendly refrigerants R290 and R170
Enucleation is a crucial event during the erythropoiesis, implicating drastic morphologic and transcriptomic/proteomic changes. While many genes deletion lead to failed or impaired enucleation have been identified, directly triggering the erythroid maturation, particularly enucleation, is still challenging. Inducing enucleation at the desired timing is necessary to develop efficient methods to gen
Objectives To study neutrophil gelatinase-associated lipocalin (NGAL) levels in peripheral blood in SLE, and to propose a mechanism by which neutrophils secrete NGAL on stimulation with immune complexes (IC). Methods NGAL was measured by ELISA in two independent Swedish SLE cohorts acting as exploratory and validation cohort (n=124 and n=308, respectively), disease controls (n=38) and healthy cont
