Ischemic stroke patients with prestroke dependency : Characteristics and long-term prognosis
Objective: This paper aims at examining the clinical characteristics of ischemic stroke patients with different levels of prestroke functional dependency, their long-term outcome, and determinants of five-year mortality. Materials and methods: We describe demographics, comorbidity, treatment, as well as long-term mortality, and functional status of 5899 prestroke-dependent ischemic stroke patients
The impact of diabetes mellitus on major amputation among patients with chronic limb threatening ischemia undergoing elective endovascular therapy- a nationwide propensity score adjusted analysis
Aim: To investigate the risk of major amputation after elective endovascular therapy in patients with chronic limb threatening ischemia (CLTI) comparing patients with and without diabetes mellitus (DM). Methods: In this nationwide cohort study, all patients registered in the Swedish Vascular Register after elective endovascular therapy for CLTI caused by infra-inguinal arterial disease from 2010 t
Diverging responses to threats across generations in zooplankton
Our understanding on how organisms evolutionarily cope with simultaneously occurring, multiple threats over generations is still elusive. In a long-term experimental study, we therefore exposed clones of a freshwater cladoceran, Daphnia magna, to threats from predation and ultraviolet radiation (UVR) during three consecutive parthenogenetic generations. We show that Daphnia can adapt to different
Migrant blackbirds, Turdus merula, have higher plasma levels of polyunsaturated fatty acids compared to residents, but not enhanced fatty acid unsaturation index
Birds have been observed to have dietary preferences for unsaturated fatty acids during migration. Polyunsaturated fatty acids (PUFAs) may increase the exercise performance of migrant birds; however, PUFAs are also peroxidation prone and might therefore incur increased costs in terms of enhanced oxidative damage in migratory individuals. To shed light on this potential constraint, we analyzed plas
Experimental and modeling study of laminar burning velocities and nitric oxide formation in premixed ethylene/air flames
Adiabatic laminar burning velocities and post-flame NO concentrations for flat, non-stretched, premixed C2 H 4 /air flames were experimentally determined with a heat flux burner of improved design, over equivalence ratios ranging from 0.7 to 2, at atmospheric pressure and initial temperature of 298 K. Recognizing that C2 H 4 is a main intermediate in high-temperature oxidation pathways of heavy hy
Temporal temperature measurement on burning biomass pellets using phosphor thermometry and two-line atomic fluorescence
We report accurate in-situ optical measurements of surface temperature, volatile gas temperature, and polycyclic aromatic hydrocarbon (PAH) emission over the whole burning history of individual biomass pellets in various combustion atmospheres. Two biomass fuels, wood and straw, were prepared in cylindrical pellets of ~300 mg. The pellets were burned in a well-controlled combustion atmosphere prov
Peer learning in clinical placements in psychiatry for undergraduate nursing students : preceptors and students’ perspective
Aim: To describe the experiences of peer learning in psychiatric inpatient settings during clinical placement of undergraduate nursing students and to highlight the possibility for peer learning in psychiatric outpatient settings. Design: A qualitative inductive design. Method: Questionnaires with 14 students and 12 preceptors in inpatient and outpatient care and interviews with one student and on
Urban Water Governance and Learning—Time for More Systemic Approaches?
Social learning, especially triple-loop social learning involving institutional and governance changes, has great potential to address urban water issues such as flooding, drought, and pollution. It facilitates urban transition and the adoption of more systemic approaches and innovations. Social learning in water governance is a growing field, but the triple-loop learning concept remains vague and
Legal culture and the CRPD
Gerard Quinn advances the proposition that there is a ‘legal culture’, which consists of unstated values and institutional expectations that underpin legal orders and constitute a ‘morality’ which enables law to be possible. He focuses on the United Nations Convention on the Rights of Persons with Disabilities (CRPD 2006), in particular on Article 12-Equal recognition before the law, to discuss th
Tools for BIM-GIS Integration (IFC Georeferencing and Conversions): Results from the GeoBIM Benchmark 2019
The integration of 3D city models with Building Information Models (BIM), coined as GeoBIM, facilitates improved data support to several applications, e.g., 3D map updates, building permits issuing, detailed city analysis, infrastructure design, context-based building design, to name a few. To solve the integration, several issues need to be tackled and solved, i.e., harmonization of features, int
Numerical study on K/S/Cl release during devolatilization of pulverized biomass at high temperature
In this paper, the interaction between different organic and inorganic K/S/Cl compounds in the solid structure of biomass is studied and a model is presented to predict the temporal release of Kg, HCl, CH 3 Cl, KCl, KOH, K2 SO4 and SO2 from biomass devolatilization. Four types of pulverized biomass are chosen from literature, two of which have no chlorine content and two with chlorine content in l
Combined fracture and mortality risk evaluation for stratifying treatment in hip fracture patients : A feasibility study
Objectives: This study aims to test the feasibility of the Fracture and Mortality Risk Evaluation (FAME) Index. Patients and methods: Two academic centers in Lithuania and Turkey participated in this retrospective study conducted between November 2018 and July 2019. A total of 100 consecutive patients (22 males, 78 females; mean age 78.9 years; range, 45 to 100 years) with low energy proximal femu

Diffusion tensor distribution imaging of an in vivo mouse brain at ultrahigh magnetic field by spatiotemporal encoding
Diffusion tensor distribution (DTD) imaging builds on principles from diffusion, solid-state and low-field NMR spectroscopies, to quantify the contents of heterogeneous voxels as nonparametric distributions, with tensor “size”, “shape” and orientation having direct relations to corresponding microstructural properties of biological tissues. The approach requires the acquisition of multiple images
A New Retinal Detachment Treatment Model for Evaluation of Vitreous Tamponades
Purpose: To develop a treatment model of rhegmatogenous retinal detachment (RRD) in which the effects of various vitreous tamponades can be explored. Methods: In a primary session, detachment was produced in the right eye of 24 rabbits using vitrectomy, posterior vitreous detachment, retinal break induction, and subretinal injection of viscoelastic solution. The following day, detachments were tre
Explicating the social constructionist perspective on crisis communication and crisis management research : a review of communication and business journals
There is a growing body of literature concerning the social construction of crisis. This study aimed to clarify inconsistencies regarding the social constructionist perspective by examining how the key terms of social constructionism are applied in crisis communication and crisis management studies. Through an analysis of 65 scholarly works in both communication and business journals, this study p
Prognostic implications of left ventricular hypertrophy diagnosed on electrocardiogram vs echocardiography
It is unclear whether 12-lead ECG employing standard criteria for left ventricular hypertrophy (LVH) provides similar information with respect to long-term cardiovascular risk as echocardiography. The authors performed a retrospective cohort study of 1376 individuals without cardiovascular disease, who underwent ECG (LVH defined using the Sokolow-Lyon voltage combination (>35 mm) or the Cornell vo
