Short- and long-term prognostic performance of exercise ECG and myocardial perfusion SPECT

Background: Myocardial perfusion SPECT (MPS) and exercise electrocardiography (Ex-ECG) results are of prognostic importance for short-term follow up duration. However, the value of MPS or Ex-ECG findings for long-term risk assessment is less evident as underlying risk factors for ischemic heart disease (IHD) gain in importance. Objectives: To assess the short- and long-term prognostic value of MPS

Structural MRI findings in the brain related to pain distribution in chronic overlapping pain conditions : An explorative case–control study in females with fibromyalgia, temporomandibular disorder-related chronic pain and pain-free controls

Background: Few neuroimaging studies have investigated structural brain differences associated with variations in pain distribution. Objective: To explore structural differences of the brain in fibromyalgia (FM), temporomandibular disorder pain (TMD) and healthy pain-free controls (CON) using structural and diffusion MRI. Methods: A case–control exploratory study with three study groups with diffe

Exploring purchase intention in metaverse retailing : Insights from an automotive platform

As an integration of cutting-edge digital technologies, the metaverse is set to revolutionize online retailing. This study employed a well-established metaverse automotive retailing platform in China to explore the paths influencing consumers' purchase intention when shopping in the metaverse. We adopted structural equation modeling to analyze the data obtained from 348 respondents who were planni

Bridging disciplines-key to success when implementing planetary health in medical training curricula

Planetary health is being or should be added to medical training curricula in accordance with association consensus. Several articles published in recent years have addressed concern on the implementation, and the challenges that can occur if not addressed properly. This scoping narrative literature review focuses on planetary health as a concept, as well as challenges and suggested solutions to a

Reduction of NOx emissions in ammonia combustion using a double-flame premixed co-combustion concept

Ammonia is a carbon-free fuel that can be produced from renewable energy sources and has the potential to replace fossil fuels, exerting a significant impact on the decarbonization of power production and propulsion industries. However, the challenge lies in the high NOx emissions, narrow flammability, and low flame speed of ammonia/air mixtures. In this paper, we study a novel concept of double-f

A Glacial–Interglacial Malacofauna Record from the Titel Loess Plateau, Serbia, between ~350 and 250 ka

We present data on molluscan fauna within the L3 loess unit (and partially within the S3 paleosol) from the key loess section of Veliki Surduk in Serbia. The section correlates to Marine Isotope Stage (MIS) 8 and late MIS 9 and, thus, spans the time frame from ~350 to 250 ka. The Veliki Surduk loess–paleosol sequence (LPS) is located on the northwestern margin of the Titel loess plateau and compri

Genomic alterations associated with resistance and circulating tumor DNA dynamics for early detection of progression on CDK4/6 inhibitor in advanced breast cancer

Combined CDK4/6 inhibitor (CDK4/6i) and endocrine therapy significantly improves outcome for patients with estrogen receptor-positive (ER+) metastatic breast cancer, but drug resistance and thus disease progression inevitably occur. Herein, we aimed to identify genomic alterations associated with combined CDK4/6i and endocrine therapy resistance, and follow the levels of specific mutations in long

Symptomatic osteonecrosis in children treated for Hodgkin lymphoma : A population-based study in Sweden, Finland, and Denmark

Background: Osteonecrosis (ON) is a potentially disabling skeletal complication of cancer treatment. Although symptomatic osteonecrosis (sON) is well-known in acute lymphoblastic leukemia (ALL), with an incidence around 6%, studies on sON in pediatric Hodgkin lymphoma (HL) are scarce. The aim of this study was to examine the incidence, risk factors, and outcome of sON in children treated for HL. P

Gastrointestinal digestion and colonic fermentation : Beyond classic food science

Several digestive system models have been developed, varying in sophistication. These models measure under dynamic, semi-dynamic, or batch conditions, with notable distinctions between them. This chapter covers models for gastrointestinal digestion, including static and dynamic models, and important aspects of digestion and fermentation, such as bioaccessibility, bioavailability, and bioconversion

Offspring sex ratio in a communal breeding bird is male-biased when pre-breeding rainfall is low

Offspring sex ratios may deviate from parity when the fitness benefits of producing male or female offspring vary. We tested for sex ratio bias in smooth-billed anis Crotophaga ani, a communal laying cuckoo with low within-group relatedness and high offspring dispersal. One male group member performs nocturnal incubation and sires more offspring than other males in the group, suggesting males may

OBESITY IS ASSOCIATED WITH CARDIOVASCULAR DISEASE IN ADULTS. IS THIS TRUE IN CHILDREN? HOW WOULD I DIAGNOSE CARDIOVASCULAR COMPLICATIONS IN THE OBESE CHILD?

Obesity is a major risk factor for metabolic and cardiovascular disease in adults. The Framingham Heart Study was established to follow the development of cardiovascular disease (CVD) over a long period of time and to identify major risk factors for premature death. 1 The study was one of the first to show that obesity is a major risk factor for CVD in adults.

Shifting Fungal Guild Abundances are Associated with Altered Temperate Forest Soil Carbon Stocks

Despite the importance of fungi to forest carbon (C) cycling and increasing calls to include microbial interactions in ecosystem models, how shifting fungal guild abundances impact soil C stocks remains poorly quantified, particularly in mineral soils where most C is stored. Additionally, a greater understanding of how fungal interguild interactions affect belowground litter decomposition is neede

‘Someone must do it’ : multiple views on family’s role in end-of-life care – an international qualitative study

Background: Family is a crucial social institution in end-of-life care. Family caregivers are encouraged to take on more responsibility at different times during the illness, providing personal and medical care. Unpaid work can be overburdening, with women often spending more time in care work than men. Objectives: This study explored multiple views on the family’s role in end-of-life care from a

MRI Signature of α-Synuclein Pathology in Asymptomatic Stages and a Memory Clinic Population

Importance: The lack of an in vivo measure for α-synuclein (α-syn) pathology until recently has limited thorough characterization of its brain atrophy pattern, especially during early disease stages. Objective: To assess the association of state-of-the-art cerebrospinal fluid (CSF) seed amplification assays (SAA) α-syn positivity (SAA α-syn+) with magnetic resonance imaging (MRI) structural measur

Shaped by boom-and-bust: a history of the Canadian mining industry since 1859

This article is concerned with the historical evolution of the mining industry in Canada since 1859. The focus is directed on changes that occurred in the industry and allows for the identification of four distinct mining regimes. These regimes are defined using the Regulation Theory, which connects conditions of production, technical progress, financial structures, and social relations. The ident

Unemployment ripple: The impact of mine closures in Canada, 1987 to 2020

Between 1980 and 2000, total employment in the Canadian mining sector halved. While the literature on resource economy is thriving in Canada, little is known about how local labor markets experienced such a decline. This article presents a novel strategy to measure the effects of mine closures on local direct, indirect, and induced employment. This ripple effect is estimated using impulse response

Micro-costing of genetic diagnostics in acute leukemia in Sweden : from standard-of-care to whole-genome sequencing

Aims and background: Whole-genome sequencing (WGS) is increasingly applied in clinical practice and expected to replace standard-of-care (SoC) genetic diagnostics in hematological malignancies. This study aims to assess and compare the fully burdened cost (‘micro-costing’) per patient for Swedish laboratories using WGS and SoC, respectively, in pediatric and adult patients with acute lymphoblastic
