A spectroscopy-based machine learning framework on photoacoustic imaging data for automatic 3D delineation of melanoma tumors

The incidence of melanoma is rising, increasing the need for efficient diagnostics. Excisional biopsy and histopathology remain the “gold standard” but often require multiple surgical incisions due to limitations in making a visual assessment of melanoma borders either by eye or using dermatoscopy. This challenge partly arises from the inability to non-invasively produce the necessary spectral con

Development of ankle and knee range of motion after isolated gastrocsoleus lengthening in children with cerebral palsy : a register-based longitudinal cohort study

Background and purpose — Outcome after gastrocsoleus lengthening in cerebral palsy (CP) is reported to be influenced by type of lengthening, age, CP subtype, and preoperative range of motion (ROM). We examined the development of ankle and knee ROM after 3 types of isolated gastrocsoleus lengthening. Methods — This is a register-based longitudinal cohort study based on data from the Swedish Cerebra

Th2 predominance and decreased NK cells in patients with hereditary angioedema

Background: In this study we included patients with hereditary angioedema (HAE) caused by decreased levels of C1 inhibitor (HAE-C1INH). An increased risk of autoimmune disorders, particularly systemic lupus erythematosus (SLE), has been reported in HAE-C1INH. This suggests that complement consumption affects adaptive immunity. Objective: To investigate lymphocyte subpopulations in relation to dise

Are There Really People With No Inner Voice? Commentary on Nedergaard and Lupyan (2024)

The idea that some people completely lack inner speech is of both scientific and popular interest. In a recent study, Nedergaard and Lupyan compared self-reporting high and low inner-speech-prevalence groups and found that participants in the low-prevalence group performed worse on a verbal working memory test and responded more slowly and less accurately during rhyme judgments. These results repr

Polycystic Ovary Syndrome and Labor Market Attachment : Sequence Analysis

Objectives: Polycystic ovary syndrome (PCOS) is an endocrine disorder in women of fertile age which may also affect the labor market attachment. We investigated labor market attachment trajectories among working age women diagnosed with PCOS. Methods: A cohort of 157,356 women born in 1975–1977 were followed annually between the ages of 30 and 39, using data from Swedish administrative registers.

ELEMENTS OF GREEN FUNCTION AND DENSITY FUNCTIONAL THEORY

If there were no Coulomb interaction among electrons, it would be relatively straightforward to solve the many-electron Schrödinger equation. It is, however, precisely this interaction that is at the heart of numerous fascinating phenomena in condensed matter physics such as superconductivity, Kondo physics, magnetism, etc. Due to the large number of electrons in a material being of the order of A

Patricio Guzman’s 1997 documentary film La memoria obstinada contains highly interesting narrative elements. These performative devices, also called re-enactments, are remarkably effective in historiographical, psychological, and cultural terms. These stylistic devices present in the Chilean director's cinematographic work manage to materialize memory within the sociocultural context to which

Increased frequency of multi-year El Niño–Southern Oscillation events across the Holocene

El Niño–Southern Oscillation (ENSO) events, whether in warm or cold phases, that persist for two or more consecutive years (multi-year), are relatively rare. Compared with single-year events, they create cumulative impacts and are linked to extended periods of extreme weather worldwide. Here we combine central Pacific fossil coral oxygen isotope reconstructions with a multimodel ensemble of transi

Inflammatory Immune Markers Associated With Thyroid Peroxidase Autoantibodies in Children Diagnosed With Both Type 1 Diabetes and Celiac Disease

Autoimmune thyroid disease (AITD) is associated with other autoimmune endocrine diseases such as type 1 diabetes (T1D) and celiac disease (CeD). Thyroid peroxidase autoantibodies (TPOA) are biomarkers of AITD but may also occur in patients with other autoimmune diseases. We examined cross-sectional correlations between TPOA and an array of immune markers in a cohort of 90 children with exclusively

The use of intravenous methylprednisolone in giant cell arteritis : a population-based study

Objectives: To determine clinical characteristics, outcome and occurrence of comorbidities in patients with biopsy-confirmed giant cell arteritis (GCA) treated with intravenous methylprednisolone (IVMP) vs those receiving oral glucocorticoids (OGC) only. Methods: A retrospective study included patients with GCA diagnosed from 2004 through 2019. Clinical and laboratory characteristics, and cumulati

Brain injury after cardiac arrest - the predictive information of computed tomography

Background and aimHypoxic-ischaemic encephalopathy (HIE) is a leading cause of morbidity and mortality in unconscious patients resuscitated after out-of-hospital cardiac arrest. Many patients die after withdrawal of life-sustaining treatments (WLST), often due to a presumed poor prognosis. To minimise the risk of premature WLST, guidelines recommend using a multimodal prognostication. Head compute

Intracranial hemorrhage before start of prophylaxis in children with hemophilia : incidence, timing, and potential for prevention

Children with hemophilia have a significantly higher risk of intracranial hemorrhage (ICH) compared to the normal population. Prophylaxis reduces the risk of ICH and earlier initiation of prophylaxis may now be feasible, especially in hemophilia A (HA). The aim of the study is to explore the potential for preventing ICH by earlier start of prophylaxis by assessing the natural course of ICH before

Laser-based Optical Diagnostics of Electrode Wear : A Pioneering Work

Improving spark-ignition engines in terms of efficiency and compatibility with renewable fuels is essential for ensuring energy security, cost-effectiveness, and sustainability. However, electrode wear of spark plugs, especially under conditions involving novel fuels and lean mixtures, becomes a significant technical challenge. Therefore, a deeper understanding of the interactions between spark di

Exploring the interaction between ambient air pollution and road traffic noise on stroke incidence in ten Nordic cohorts

Introduction: Ambient air pollution and road traffic noise are stroke risk factors, but evidence on their potential joint effects remains limited. This study investigated the independent and joint associations of air pollution and road traffic noise on stroke incidence using both multiplicative and additive scales. Methods: We followed stroke incidence in ten cohorts in Sweden, Denmark, and Finlan

Cerebrospinal fluid platelet-derived growth factor receptor-beta is negatively correlated with depressive symptom severity in suicide attempters

Background: Depression and suicidal behavior have been linked to increased blood-brain barrier (BBB) permeability. Platelet-derived growth factor receptor beta (PDGFR-β) is widely expressed in pericytes and promotes BBB integrity. Here, we investigated cerebrospinal fluid (CSF) levels of PDGFR-β in suicide attempters and healthy controls and correlated PDGFR-β to depression symptom severity. Metho

The prognostic value of global longitudinal strain in patients with myocardial infarction and preserved ejection fraction : a prespecified substudy of the REDUCE-AMI trial

Aims The REDUCE-AMI trial showed that beta-blockers in patients with preserved left ventricular ejection fraction (LVEF) after acute myocardial infarction (AMI) had no effect on mortality or cardiovascular outcomes. The aim of this substudy was to evaluate whether global longitudinal strain (GLS) is a better prognostic marker than LVEF, and if beta-blockers have a beneficial effect in patients wit
