Oral corticosteroid use, morbidity and mortality in asthma : A nationwide prospective cohort study in Sweden

Background: Patterns and determinants of long-term oral corticosteroid (OCS) use in asthma and related morbidity and mortality are not well-described. In a nationwide asthma cohort in Sweden, we evaluated the patterns and determinants of OCS use and risks of OCS-related morbidities and mortality. Methods: Data for 217 993 asthma patients (aged ≥ 6 years) in secondary care were identified between 2

A new perspective for advanced positron emission tomography–based molecular imaging in neurodegenerative proteinopathies

Recent studies in neurodegenerative conditions have increasingly highlighted that the same neuropathology can trigger different clinical phenotypes or, vice-versa, that similar phenotypes can be triggered by different neuropathologies. This evidence has called for the adoption of a pathology spectrum-based approach to study neurodegenerative proteinopathies. These conditions share brain deposition

Designing motivating interactive balance and walking training for stroke survivors

In the ActivAbles and STARR projects we are developing interactive training tools for stroke survivors. Our initial user studies pointed to balance being a key ability, therefore one of the developed tools is an interactive balance pad. Equipment exists for persons with good balance (eg. Wii), but most consumer games and exercises are less suited for many stroke survivors. The development process

A review of in situ real-time monitoring techniques for membrane fouling in the biotechnology, biorefinery and food sectors

Pressure-driven membrane processes are often used for the separation and purification of organic compounds originating from biomass. However, membrane fouling remains a challenge as these bio-based streams have a very complex composition and comprise a high fouling tendency. Conventional, the fouling is monitored based on either a decrease in flux or an increase in pressure over time. Those conven

Prospects for powering past coal

To keep global warming within 1.5 °C of pre-industrial levels, there needs to be a substantial decline in the use of coal power by 20301,2 and in most scenarios, complete cessation by 2050. The members of the Powering Past Coal Alliance (PPCA), launched in 2017 at the UNFCCC Conference of the Parties, are committed to “phasing out existing unabated coal power generation and a moratorium on new coa

Heat transfer analysis on dimple geometries and arrangements in dimple jacketed heat exchanger

Purpose: The purpose of this paper is to study the effects of dimple geometries and arrangements on the heat transfer enhancement in a dimple jacketed heat exchanger. Design/methodology/approach: For the purpose of this paper, with the experimental validated numerical model, this paper carries out numerical simulations of both single dimples with different geometries and the whole dimple jacketed

Increased functional connectivity of thalamic subdivisions in patients with Parkinson’s disease

Parkinson’s disease (PD) affects 2–3% of the population over the age of 65 with loss of dopaminergic neurons in the substantia nigra impacting the functioning of basal ganglia-thalamocortical circuits. The precise role played by the thalamus is unknown, despite its critical role in the functioning of the cerebral cortex, and the abnormal neuronal activity of the structure in PD. Our objective was

A complexity perspective on logistics management : Rethinking assumptions for the sustainability era

Purpose: The purpose of this paper is to elaborate on how perspectives and assumptions embedded in the complexity paradigm contribute to make logistics management research better aligned with real-life logistics. This is necessary, due to increasing supply chain complexity caused by an increasing request for sustainable development (SD). Design/methodology/approach: The research is exploratory and

A SEMI-ANALYTIC MODEL OF TIDAL INLETS AND THEIR EVOLUTION

The water exchange between the sea and a lagoon or bay through an inlet due to tides is a classical topic that has been investigated in a large number of studies (Keulegan, 1967; O’Brien and Dean, 1972; O’Brien and Clark, 1974; Escoffier, 1977). In this paper, a simple semi-analytic model of the flow induced by tides through an inlet connecting the sea to a lagoon or bay is developed. The model is

Scoliosis in cerebral palsy

Cerebral pares (CP) är den vanligaste orsaken till motorisk funktionsnedsättning hos barn och ungdomar och årligen föds ca 200 barn med CP i Sverige. Symtomen vid CP varierar, men karaktäriseras av bland annat nedsatt rörelseförmåga och nedsatt förmåga att stabilisera kroppen. Nästan åtta av tio vuxna med CP besväras av korta och spända muskler, snedställda leder och smärta som påverkar deras funkBackgroundIndividuals with cerebral palsy (CP) have an increased risk for scoliosis, especially those with low gross motor function, affecting both quality of life and overall function. The aims were to increase the knowledge on the development of, and predictors for scoliosis and the use of spinal orthoses in individuals with CP, and also to evaluate the Caregiver Priorities and Child Health Inde

A Single-Electron Transistor Made of a 3D Topological Insulator Nanoplate

Quantum confined devices of 3D topological insulators are proposed to be promising and of great importance for studies of confined topological states and for applications in low-energy-dissipative spintronics and quantum information processing. The absence of energy gap on the topological insulator surface limits the experimental realization of a quantum confined system in 3D topological insulator

A minimal model for the latitudinal diversity gradient suggests a dominant role for ecological limits

The latitudinal diversity gradient (LDG) is one of Earth’s most iconic biodiversity patterns and still one of the most debated. Explanations for the LDG are often categorized into three broad pathways in which the diversity gradient is created by (1) differential diversification rates, (2) differential carrying capacities (ecological limits), or (3) differential time to accumulate species across l

Groundwater depletion estimated from GRACE : A challenge of sustainable development in an arid region of Central Asia

Under climate change and increasing water demands, groundwater depletion has become regional and global threats for water security, which is an indispensable target to achieving sustainable developments of human society and ecosystems, especially in arid and semiarid regions where groundwater is a major water source. In this study, groundwater depletion of 2003-2016 over Xinjiang in China, a typic

Health-related quality of life and glycaemic control among adults with type 1 and type 2 diabetes - A nationwide cross-sectional study

Background: Health-related quality of life and glycaemic control are some of the central outcomes in clinical diabetes care and research. The purpose of this study was to describe the health-related quality of life and assess its association with glycaemic control in adults with type 1 and type 2 diabetes in a nationwide setting. Methods: In this cross-sectional survey, people with type 1 (n = 247

Bile but not chyle lipoprotein is an important source of arachidonic acid for the rat small intestine

Arachidonic acid (AA) functions as a structural component, eicosanoid precursor and surface material for chylomicron production in the gastrointestinal tract. The origin of this AA is poorly characterized. [3H]AA labelled chylomicrons and [14C]AA albumin-FFA were injected intravenously into biliary diverted rats and controls. Radioactivity in tissue lipids was measured after different time interva

Från guldmyntfot till inflationsmål – svensk stabiliseringspolitik under det 20:e seklet

Under 1900-talet har målen, medlen, institutionerna samt strategin för penning- och finanspolitiken befunnit sig i ständig omvandling, främst orsakad av djupa ekonomiska kriser. Detta mönster antyder att även 2000-talet kommer att se fundamentala omprövningar i stabiliseringspolitiken när framtidens kriser träffar svensk ekonomi. 1900-talets stabiliseringspolitik har dominerats av guldmyntfoten me

Den nya ekonomin i ett historiskt perspektiv

Den nya ekonomin har inspirerat till djärva utsagor om vår ekonomiska framtid. Här granskas fem sådana utifrån ett historiskt perspektiv. Hur påverkar den nya ekonomin följande fem fenomen: konjunkturcykeln, de ekonomiska kriserna, inflationen, stabiliseringspolitiken samt den svenska modellen? Svaren är förvisso preliminära men pekar på att den nya ekonomin på vissa områden inte leder till någon
