Introduction: Postoperative delirium is a common complication after cardiac surgery with cardiopulmonary bypass (CPB). Compromised regulation of the cerebral circulation may be a predisposing factor for delirium. However, the potential relationship between cerebrovascular reserve capacity and delirium is unknown. The aim of this study was to investigate if impaired cerebrovascular reserve capacity
Mutations in either mitochondrial DNA (mtDNA) or nuclear genes that encode mitochondrial proteins may lead to dysfunctional mitochondria, giving rise to mitochondrial diseases. Some mitochondrial myopathies, however, present without a known underlying cause. Interestingly, methylation of mtDNA has been associated with various clinical pathologies. The present study set out to assess whether mtDNA
BACKGROUND: To benefit from available care and treatment options, patients should first be counselled and tested for HIV. Our aim was to assess the acceptability of HIV testing among tuberculosis patients under routine care conditions in south Ethiopia.METHODS: We interviewed all adult tuberculosis patients who were treated at Arba Minch Hospital in Ethiopia between January and August 2005. After
An ECG risk-score has been described that predicts high risk of subsequent cardiac arrest in young patients with hypertrophic cardiomyopathy (HCM). Myocardial fibrosis measured by cardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) also affects prognosis. We assessed whether an ECG risk-score could be used as an indicator of myocardial fibrosis or perfusion deficit on CMR in HCM. In
Traumatic brain injury (TBI) and repeated sports-related concussions (rSRCs) are associated with an increased risk for neurodegeneration. Autopsy findings of selected cohorts of long-term TBI survivors and rSRC athletes reveal increased tau aggregation and a persistent neuroinflammation. To assess in vivo tau aggregation and neuroinflammation in young adult TBI and rSRC cohorts, we evaluated 9 hea
Glycosaminoglycans (GAGs) are structurally heterogeneous negatively charged polysaccharides. Endothelial GAGs, also known as glycocalyx, are involved in capillary permeability. In rat venules stimulated with proinflammatory substances ex vivo, the GAG-containing proteoglycan, syndecan-1, is shed from the endothelium. We wanted to investigate if we could trace the same response during septic shock
There is still a need for new agents which improve upon the therapeutic index of tiotropium, the current standard of care for many patients with chronic obstructive pulmonary disease (COPD). We examined in patients with COPD the efficacy of single doses of AZD9164, an M(3)-selective muscarinic antagonist, to identify an appropriate dose-range for future studies. COPD patients (n = 28) inhaled AZD9
Purpose: To analyse risk of vision impairment (VI) and blindness in adult foreign-born individuals and Swedish-born individuals. Methods: A nationwide study of individuals 18 years of age and older (N = 6,042,891; 2,902,918 men and 3,139,973 women) in Sweden. VI (in general) and blindness was defined as at least one registered diagnosis in the National Patient Register between January 1, 1998 and
Background: In adults and adolescents with asthma, use of ≥3 short-acting β2-agonist (SABA) canisters/year is associated with increased exacerbation risk. Whether this association is present in younger children remains unknown. In this SABA use IN Asthma (SABINA) Junior study, we assessed the association of SABA collection with exacerbation risk in the general Swedish pediatric asthma population.
Superficial CD34-positive fibroblastic tumor (SCD34FT) is a rare soft tissue neoplasm that shows overlapping features with PRDM10-rearranged soft tissue tumor (PRDM10-STT). This study characterizes the clinicopathologic, immunohistochemical, and molecular features of SCD34FT in a series of 59 cases. Fluorescence in situ hybridization to assess for PRDM10 rearrangement was performed in 12 tumors. I
Objective: This study examined two Death-Implicit Association Test versions targeting associations between the self-concept (standard identity D-IAT; iD-IAT) and internal versus external control (adapted control D-IAT; cD-IAT) and death among suicide attempters. Additionally, correlations with explicit psychological variables and psychometrics were explored. Method: 116 psychiatric inpatients (58.
A novel metabolomic method based on gas chromatography-mass spectrometry was applied to investigate serum metabolites in response to dietary Gln supplementation in piglets. Sixteen, 21-d-old pigs were weaned and assigned randomly to 2 isonitrogenous diets: 1) Gln diet, which contained 1% L-Gln (as-fed basis), and 2) control diet, which contained LAla to make this diet isonitrogenous with the Gln d
Objective High vitreous levels of soluble (s)CD163 have been demonstrated in severe diabetic retinopathy (DR). The aim of this study was to explore the predictive values of plasma sCD163 and glycated haemoglobin (HbA1c) for DR progression in adults with type 1 diabetes. Methods and analyses The study design was prospective. Fundus photography performed in 2009 and at follow-up (≤12 years later) we
Introduction: Airway management is a critical component of out-of-hospital cardiac arrest (OHCA) resuscitation. The primary aim of this study was to describe pre-hospital airway management in adult patients post-OHCA. Secondary aims were to investigate whether tracheal intubation (TI) versus use of supraglottic airway device (SGA) was associated with patients’ outcomes, including ventilator-free d
The Arctic is undergoing a shift toward a warmer and wetter climate. Recent experiments indicate that the carbon balance of subarctic wet tundra is sensitive to both summer warming and deeper snow. However, few studies have combined experimental data with process-oriented models to predict how the terrestrial carbon cycle will respond to future climate change. Here, we use CoupModel, a process-ori
Background: Premature ventricular complexes (PVCs) predict coronary heart disease, heart failure, atrial fibrillation and death, all of which are also related to sodium intake. We studied estimated sodium intake and PVC frequency in the randomly selected population-based Swedish CArdioPulmonary bioImage Study cohort. Methods: In our cross-sectional study, we included 5636 individuals with 24-hour
Methanol (CH3OH) is an attractive alternative fuel that can reduce net carbon release and decrease pollutant emissions. In this study, methanol and n-dodecane spray flames were investigated using Large-Eddy Simulation (LES) and direct coupling with finite-rate chemistry. The selected ambient conditions are relevant to engines and were previously unreported for numerical methanol spray studies, i.e
Rationale: Long-term oxygen therapy (LTOT) is prescribed for at least 15 hours per day and often used by patients for several years, but knowledge is limited regarding adverse effects, risk exposures, and health-related quality of life (HrQoL) among those treated. Objectives: To determine the prevalence of adverse effects, smoking, and alcohol consumption and their relations to HrQoL among patient
