Predicting self-injurious thoughts in daily life using ambulatory assessment of state cognition
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-12)Self-injurious thoughts (SITs) fluctuate considerably from moment to moment. As such, “static” and temporally stable predictors (e.g., demographic variables, prior history) are suboptimal in predicting imminent SITs. This concern is particularly true for “online” cognitive abilities, which are important for understanding SITs, but are typically measured using tests selected for temporal stability. ... -
The effect of train-the-colonoscopy-trainer course on colonoscopy quality indicators
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-23)Background - Systematic training in colonoscopy is highly recommended; however, we have limited knowledge of the effects of “training-the-colonoscopy-trainer” (TCT) courses. Using a national quality register on colonoscopy performance, we aimed to evaluate the effects of TCT participation on defined quality indicators.<p> <p>Methods - This observational study compared quality indicators (pain, ... -
Intramuscular uptake of tranexamic acid during haemorrhagic shock in a swine model
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-18)Background: Tranexamic acid (TXA) reduce mortality in bleeding trauma patients, with greater efect if administered early. Serum concentrations above 10 µg/mL are considered sufcient to inhibit fbrinolysis. Normally administered intravenously (i.v.), TXA can also be administered intramuscularly (i.m.). This could be advantageous in low resource and military settings, if sufcient serum concentrations ... -

Elevated plasma D-dimer levels are associated with risk of future incident venous thromboembolism
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-25)<p><i>Background</i> D-dimer, a global biomarker for activation of the coagulation and fibrinolysis systems, is useful in assessing individual risk of venous thromboembolism (VTE) recurrence. However, there is limited information on the association between D-dimer and risk of a first lifetime VTE event. <p><i>Objectives</i> To investigate the association between plasma D-dimer levels and risk of ... -
The LabBM score is an excellent survival prediction tool in patients undergoing palliative radiotherapy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-16)Background and aim: The prognostic assessment of patients referred for palliative radiotherapy can be conducted by sitespecific scores. A quick assessment that would cover the whole spectrum could simplify the working day of clinicians who are not specialists for a particular disease site. This study evaluated a promising score, the LabBM (validated for brain metastases), in patients treated for ... -
Kennedy disease in two sisters with biallelic CAG expansions of the androgen receptor gene
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-19)We present a retrospective 21-year follow-up of two sisters with X-linked biallelic CAG expansions in the androgen receptor (AR) gene causing Kennedy disease. Two sisters inherited CAG expansions from their mother who was a carrier and their father who had Kennedy disease. Genetic testing revealed alleles comprising 43/45, and 43/43 CAG repeats in the younger and older sister, respectively. They ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-19)<i><p>Background</i> Vitamin D has been linked to sleep health in observational studies. Data from randomized controlled trials (RCTs) with vitamin D is scarce. <i><p>Methods</i> This study presents the results of a secondary analysis of 189 vitamin D insufficient participants (47.1% women) in a previously performed RCT, of which 92 were randomized to vitamin D (100,000 IU (2500 μg) as a ... -
Randomized Trial of Interleukin-6 Receptor Inhibition in Patients With Acute ST-Segment Elevation Myocardial Infarction
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-12)<p><i>Background - </i>Prompt myocardial revascularization with percutaneous coronary intervention (PCI) reduces infarct size and improves outcomes in patients with ST-segment elevation myocardial infarction (STEMI). However, as much as 50% of the loss of viable myocardium may be attributed to the reperfusion injury and the associated inflammatory response. <p><i>Objectives - </i>This study sought ... -
An artificial neural network approach integrating plasma proteomics and genetic data identifies PLXNA4 as a new susceptibility locus for pulmonary embolism
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-07)Venous thromboembolism is the third common cardiovascular disease and is composed of two entities, deep vein thrombosis (DVT) and its potential fatal form, pulmonary embolism (PE). While PE is observed in~ 40% of patients with documented DVT, there is limited biomarkers that can help identifying patients at high PE risk. To fll this need, we implemented a two hidden-layers artifcial neural ... -

Identifying anti-TNF response biomarkers in ulcerative colitis using a diffusion-based signalling model
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-18)<p><i>Motivation:</i> Resistance to anti-TNF therapy in subgroups of ulcerative colitis (UC) patients is a major challenge and incurs significant treatment costs. Identification of patients at risk of nonresponse to anti-TNF is of major clinical importance. To date, no quantitative computational framework exists to develop a complex biomarker for the prognosis of UC treatment. Modelling patient-wise ... -
Decompression with or without Fusion in Degenerative Lumbar Spondylolisthesis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-05)BACKGROUND In patients with lumbar spinal stenosis and degenerative spondylolisthesis, it is uncertain whether decompression surgery alone is noninferior to decompression with instrumented fusion. METHODS We conducted an open-label, multicenter, noninferiority trial involving patients with symptomatic lumbar stenosis that had not responded to conservative management and who had single-level ... -
Remote Monitoring of CIEDs—For Both Safety, Economy and Convenience?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-28)Cardiac implantable electronic devices such as pacemakers and defibrillators are increasingly monitored by systems transmitting information directly from the patient to the hospital. This may increase safety and patient satisfaction and also under certain circumstances represent an economic advantage. The review summarizes some of the recent research in the field of remote monitoring of cardiac devices.
