Background: Emergency surgery for acute type A aortic dissection in patients with previous cardiac surgery is controversial. This study aimed to evaluate the association between previous cardiac surgery and outcomes after surgery for acute type A aortic dissection, to appreciate whether emergency surgery can be offered with acceptable risks. Methods: All patients operated on for acute type A aorti

Phytochemicals have been used as one of the sources for the development of anti-obesity drugs. Plants are rich in a variety of bioactive compounds including polyphenols, saponins and terpenes. Phytochemicals inhibit adipocyte differentiation by inhibiting the transcription and translation of adipogenesis transcription factors such as C/EBPα and PPARγ. It has been proved that phytochemicals inhibit

The city of Copenhagen, often celebrated as one of the world’s greenest for its cycling culture and other initiatives, recently defaulted on its pledge to become carbon-neutral by 2025. This early failure in the global race to net zero emissions (a balance between CO₂ emitted and absorbed) may foreshadow backtracking by other target-setters, indicating that pledges to cease contributing to climate

This study provides a cross-platform, longitudinal investigation of pictures depicting political candidates posted to Facebook and Instagram over a 15-month period during the 2020 US election(n = 4,977). After motivating an exploratory research design, we set out to expound: the extent of cross-platform image posting across Facebook and Instagram; the emotion expression of politicians across the t

Spectra emitted from laser-produced plasmas of scandium, titanium, vanadium and chromium have been recorded in the region 270-600 Å, and lines belonging to the 3s-3p and 3p-3d transition arrays in neonlike ions have been identified. The 2p53s, 3p and 3d energy levels have been derived from the observations for Ti XIII and from solar flare lines for Fe XVII. Hartree-Fock calculations and parametric

OBJECTIVE: To report the mid-term outcomes of fenestrated-branched endovascular aneurysm repair (F-BEVAR) following a failed previous endovascular aneurysm repair (pEVAR) or previous open aneurysm repair (pOAR).METHODS: Data from consecutive patients who underwent F-BEVAR for pEVAR or pOAR from 2006-2021 from 17 European vascular centres were analyzed. Endpoints included technical success, major a

This article discusses the way folklorists and ethnologists gathered online during the Covid-19 pandemic to collect and share online humour. The ethnographers’ instinct during aglobal crisis was to immediately start documenting emerging cultural expressions, particu-larly digital humour. They came together in Facebook groups aimed more or less explicitlyto function as collective collection efforts

Syftet med den här artikeln är att se närmare på kopplingen mellan positioner som framkommer i Finlandssvenska, manliga berättelser om skolprestation och affekten skam. Genom att se till positionerad underlägsenhetoch överlägsenhet, vill jag illustrera hur skam har en funktion i det berättade. Över och underlägsenhet används sompositionering mot berättelsen om skolprestation och gentemot föreställThe aim of this article is to illustrate the connection between narrative positioning and qualia in the re-telling of Finn-Swede boyhoods; and the function of shame. Shame works as an affective backdrop to male stories of school and achievement. The shame is constructed by master narrative positioning and shows a resistance to cultural certainties regarding boy’s school performance in a Finnish co

Background: Patients with chronic diseases create their own subjective beliefs about their conditions based on their illness perceptions. In the common-sense model, illness perceptions constitute personal beliefs about illness with regard to five components: identity, timeline, cause, control/cure, and consequences. Patients’ illness perceptions affect both their management of their disease and th

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

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

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

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

In a recent study, Bai (2013) proposes a new factor analytical (FA) method for estimation of stationary dynamic panel data models with fixed effects. Our interest in this method originates with the fact it does not require explicit demeaning of the data, a practice that is known to cause problems of bias and low power in near unit root panels. The purpose is to study the properties of FA when appl

Purpose: To explore patients’ preferred treatment outcomes during their first two years with rheumatoid arthritis (RA). Patients and Methods: A qualitative, longitudinal, multicenter study with interviews at two time points was performed in Sweden. Individual interviews were conducted at time point 1 with 31 patients with RA, defined as disease duration of ≤1 year and treatment for 3–7 months. Sev

The purpose of the paper is to explore knowledge accumulation in research on pedagogy in entrepreneurship education, with particular attention to how core journal outlets, core topics and core scholarly works have developed over time. The authors combine a systematic literature review technique and bibliometric analysis to depict the development of this stream of research in the period 1995–2018. The purpose of the paper is to explore knowledge accumulation in research on pedagogy in entrepreneurship education, with particular attention to how core journal outlets, core topics and core scholarly works have developed over time. The authors combine a systematic literature review technique and bibliometric analysis Findings from the analyses suggests that research addressing pedagogy in entre

Background: Severe alpha-1-antitrypsin deficiency (AATD), phenotype PiZZ, was associated with venous thromboembolism (VTE) in a case-control study. Objectives: This study aimed to determine the genetic variation in the SERPINA1 gene and a possible thrombotic risk of these variants in a population-based cohort study. Patients/Methods: The coding sequence of SERPINA1 was analyzed for the Z (rs289294

Given a directed graph as input, we show how to efficiently find a shortest (directed, simple) cycle on an even number of vertices. As far as we know, no polynomial-time algorithm was previously known for this problem. In fact, finding any even cycle in a directed graph in polynomial time was open for more than two decades until Robertson, Seymour, and Thomas (Ann. of Math. (2) 1999) and, independ

Integrating fast pyrolysis into existing biomass-based combined heat and power (CHP) plants offers an innovative opportunity for plant operators to acquire an additional heat sink and produce a renewable transport fuels feedstock. This technology is particularly interesting in Sweden, where biobased heat and power constitute an important part of the energy system. It is important to establish the
