Motivationsfaktorer för användning av sociala media-tjänster: Samband med psykiskt mående, livskvalitet och problematisk användning

Motivationsfaktorer för användning av sociala media-tjänster är ett område som det i dagsläget finns begränsat med forskning om. I denna tvärsnittsstudie har syftet varit att utforska samband mellan motivationsfaktorer för användning av sociala media tjänster, problematiskt bruk av sociala media-tjänster, psykiskt mående och livskvalitet. Skillnader mellan de som identifierat sig som kvinnor respeMotivations for social media use is a topic where there is currently a limited amount of research. The purpose of this cross-sectional study was to study correlations between motivations for social media use, problematic use of social media services, mental well-being, and quality of life. Differences between those who identified themselves as women and men were also studied. Data collection was d

In Certain Remembrance: a Meta-Analysis on the Relationship Between Confidence and Accuracy in Episodic Memory

I en metaanalys granskades litteraturen om sambandet mellan konfidens och korrekthet i episodiskt minne, med särskilt fokus på minne för brottsrelaterade händelseförlopp vid fri och styrd återgivning. Trots omfattande forskning inom området identifierades en lucka inom forskningsfältet, då ingen tidigare meta- analys specifikt behandlat sambandet mellan konfidens och korrekthet för fri och styrd åThis meta-analysis reviewed the literature on the relationship between confidence and accuracy in episodic memory, specifically focusing on crime- relevant event memory in free and cued recall. Despite extensive research in this area, an apparent gap was identified within memory research, as no prior meta-analysis has addressed the relationship between confidence and accuracy in the context of fre

Thrombospondin-4 deletion does not exacerbate muscular dystrophy in β-sarcoglycan-deficient and laminin α2 chain-deficient mice

Muscular dystrophy is a group of genetic disorders that lead to muscle wasting and loss of muscle function. Identifying genetic modifiers that alleviate symptoms or enhance the severity of a primary disease helps to understand mechanisms behind disease pathology and facilitates discovery of molecular targets for therapy. Several muscular dystrophies are caused by genetic defects in the components

Vegetation resistance to increasing aridity when crossing thresholds depends on local environmental conditions in global drylands

The crossing of aridity thresholds triggers abrupt changes in multiple functional and structural ecosystem attributes across global drylands. While we understand the consequences associated with aridity thresholds, the key factors influencing dryland vegetation resistance when crossing them remain unclear. Here, we used field observations from 58 dryland sites across five continents and satellite

Relative decline in density of Northern Hemisphere tree species in warm and arid regions of their climate niches

Although climate change is expected to drive tree species toward colder and wetter regions of their distribution, broadscale empirical evidence is lacking. One possibility is that past and present human activities in forests obscure or alter the effects of climate. Here, using data from more than two million monitored trees from 73 widely distributed species, we quantify changes in tree species de

Reservoir-excess pressure parameters are independently associated with NT-proBNP in older adults

AIMS: Parameters derived from reservoir-excess pressure analysis have been demonstrated to predict cardiovascular events. Thus, altered reservoir-excess pressure parameters could have a detrimental effect on highly-perfused organs like the heart. We aimed to cross-sectionally determine whether reservoir-excess pressure parameters were associated with N-terminal pro-brain-type natriuretic peptide (

Unveiling the drivers of atmospheric methane variability in Iran : A 20-year exploration using spatiotemporal modeling and machine learning

Understanding the factors controlling spatial and temporal variability of atmospheric methane concentration (XCH4) is crucial for mitigating its impacts and implementing emission reduction strategies. This study comprehensively investigates XCH4 and its driving factors (environmental, meteorological, and anthropogenic activity) across Iran over 20 years, from 2003 to 2022. It combines multi-source

Prevalence of diabetes and hospitalization due to poor glycemic control in people with bladder cancer or renal cell carcinoma in Sweden

Background: Bladder cancer (BC) and Renal cell carcinoma (RCC) are the most common urogenital cancers among both sexes, with a yearly global incidence of around 500 000 each. Both BC and RCC have been linked to diabetes. Poor glycemic control (malglycemia) is a serious consequence of diabetes and a possible consequence of systemic treatments used in BC and RCC. The objective of this study was to i

The predictive value of cardiovascular outcomes and mortality assessed by the C-reactive protein to albumin ratio in the UK Biobank

Background: The C-reactive protein/albumin ratio (CAR) seems to mirror disease severity and prognosis in several acute disorders particularly in elderly patients, yet less is known about if CAR is superior to C-reactive protein (CRP) in the general population. Methods: Prospective study design on the UK Biobank, where serum samples of CRP and Albumin were used. Cox regression analyses were conduct

Combined use of the Montreal Cognitive Assessment and Symbol Digit Modalities Test improves neurocognitive screening accuracy after cardiac arrest : A validation sub-study of the TTM2 trial

AimTo assess the merit of clinical assessment tools in a neurocognitive screening following out-of-hospital cardiac arrest (OHCA).MethodsThe neurocognitive screening that was evaluated included the performance-based Montreal Cognitive Assessment (MoCA) and Symbol Digit Modalities Test (SDMT), the patient-reported Two Simple Questions (TSQ) and the observer-reported Informant Questionnaire on CogniAim: To assess the merit of clinical assessment tools in a neurocognitive screening following out-of-hospital cardiac arrest (OHCA).Methods: The neurocognitive screening that was evaluated included the performance-based Montreal Cognitive Assessment (MoCA) and Symbol Digit Modalities Test (SDMT), the patient-reported Two Simple Questions (TSQ) and the observer-reported Informant Questionnaire on C

Amniotic fluid derived mesenchymal stem cells reduce inflammation and improve lung function following transplantation in a porcine model

BACKGROUND: Lung transplantation is hindered by low donor lung utilization rates. Infectious complications are reasons to decline donor grafts due to fear of post-transplant primary graft dysfunction. Mesenchymal stem cells are a promising therapy currently investigated in treating lung injury. Full-term amniotic fluid-derived lung-specific mesenchymal stem cell treatment may regenerate damaged lu

STEMI, Revascularization, and Peak Troponin by Adverse Pregnancy Outcomes in Women With Myocardial Infarction

BACKGROUND: Women with a history of adverse pregnancy outcomes have a higher risk of coronary heart disease. Emerging evidence suggests that women with a history of preeclampsia have a different pattern of overall coronary atherosclerosis and that they at the time of myocardial infarction (MI) more frequently present with ST-segment elevation MI (STEMI) compared to women with no such history.OBJEC

Fast Relative Pose Estimation using Relative Depth

In this paper, we revisit the problem of estimating the relative pose from a sparse set of point-correspondences. For each point-correspondence we also estimate the relative depth, i.e. the relative distance to the scene point in the two images. This yields an additional constraint, allowing us to use fewer matches in RANSAC to generate the pose candidates. In the paper we propose two novel minima

The Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aerospace Exploration Agency. JASMINE has two main science goals. One is Galactic archaeology with a Galactic Center survey, which aims to reveal the Milky Way's central core structure and formation history from Gaia-lev

More than Just a Game: Teachers’ Experiences of PAX-GBG

The PAX Good Behavior Game (PAX-GBG) is an evidence-based universal preventive intervention program for classroom use. Our aim was to explore teachers' perceptions of PAX-GBG and their work with it, and whether this changed during the implementation of the intervention. In addition, we explored teachers' perceptions, and changes in perceptions, regarding how they perceived their workload when lear

Artificial intelligence and radiologists in prostate cancer detection on MRI (PI-CAI): an international, paired, non-inferiority, confirmatory study

Background: Artificial intelligence (AI) systems can potentially aid the diagnostic pathway of prostate cancer by alleviating the increasing workload, preventing overdiagnosis, and reducing the dependence on experienced radiologists. We aimed to investigate the performance of AI systems at detecting clinically significant prostate cancer on MRI in comparison with radiologists using the Prostate Im

Vad kokar i den ryska mediakitteln? En analys av användningen av begreppen sjajtany, desjajtanizatsija och desatanizatsija i rysk media under 2022

Abstract: The purpose of this study is to investigate how Russia communicates with their religious and ethnic minorities on the invasion of Ukraine. To do this I have studied the use of the words “shaytany”, “shaytanizatsia” and “desatanizatsia” describing Ukrainians and the invasion of Ukraine in Russian state-controlled media during 2022. My hypothesis was that these words are used in a narrativ
