Intravenous Iron Treatment in the Prevention of Iron Deficiency and Anaemia After Roux-en-Y Gastric Bypass
(Peer reviewed; Journal article, 2020)Background Iron absorption is disturbed after Roux-en-Y gastric bypass (RYGB) and iron deficiency with or without anaemia affects almost half of all patients. Intravenous iron is an option when per oral iron is insufficient ... -
Intraventricular Vector Flow Imaging with Blood Speckle Tracking in Adults: Feasibility, Normal Physiology and Mechanisms in Healthy Volunteers
(Peer reviewed; Journal article, 2021)This study examines the feasibility of blood speckle tracking for vector flow imaging in healthy adults and describes the physiologic flow pattern and vortex formation in relation to the wall motion in the left ventricle. ... -
Introducing fairness in Norwegian air ambulance base location planning
(Peer reviewed; Journal article, 2021)Background A primary task of the Norwegian helicopter emergency medical services (HEMS) is to provide advanced medical care to the critical ill and injured outside of hospitals. Where HEMS bases are located, directly ... -
The introduction of a regional Norwegian HEMS coordinator: an assessment of the effects on response times, geographical service areas and severity scores
(Peer reviewed; Journal article, 2022)Background Due to unwanted delays and suboptimal resource control of helicopter emergency medical services (HEMS), regional HEMS coordinators have recently been introduced in Norway. This may represent an unnecessary ... -
Investigating a Potential Causal Relationship Between Maternal Blood Pressure During Pregnancy and Future Offspring Cardiometabolic Health
(Peer reviewed; Journal article, 2021)Observational epidemiological studies have reported that higher maternal blood pressure (BP) during pregnancy is associated with increased future risk of offspring cardiometabolic disease. However, it is unclear whether ... -
Investigating causal relations between sleep traits and risk of breast cancer in women: Mendelian randomisation study
(Peer reviewed; Journal article, 2019)Objective To examine whether sleep traits have a causal effect on risk of breast cancer. Design Mendelian randomisation study. Setting UK Biobank prospective cohort study and Breast Cancer Association Consortium ... -
Investigating novel biomarkers of immune activation and modulation in the context of sedentary behaviour: a multicentre prospective ischemic stroke cohort study
(Peer reviewed; Journal article, 2021)Background Sedentary behaviour is associated with disease, but the molecular mechanisms are not understood. Valid biomarkers with predictive and explanatory properties are required. Therefore, we have investigated traditional ... -
Investigating optimal β-cell-preserving treatment in latent autoimmune diabetes in adults: Results from a 21-month randomized trial
(Peer reviewed; Journal article, 2019)Aims To compare outcomes of glucagon‐stimulated C‐peptide tests (GSCTs) in people with latent autoimmune diabetes in adults (LADA) after a 21‐month intervention with either insulin or the dipeptidyl peptidase‐4 inhibitor ... -
Investigating survival, quality of life and cognition in PROton versus photon therapy for IDH- mutated diffuse grade 2 and 3 GLIOmas (PRO-GLIO): a randomised controlled trial in Norway and Sweden
(Peer reviewed; Journal article, 2023)Abstract Introduction The use of proton therapy increases globally despite a lack of randomised controlled trials demonstrating its efficacy and safety. Proton therapy enables sparing of non-neoplastic tissue from ... -
Investigating the causal interplay between sleep traits and risk of acute myocardial infarction: a Mendelian randomization study
(Peer reviewed; Journal article, 2023)Background Few studies have investigated the joint effects of sleep traits on the risk of acute myocardial infarction (AMI). No previous study has used factorial Mendelian randomization (MR) which may reduce confounding, ... -
Investigating the effect of sex and ketosis on weight-loss-induced changes in appetite
(Peer reviewed; Journal article, 2019)Background Diet-induced weight loss (WL) is usually accompanied by increased appetite, a response that seems to be absent when ketogenic diets are used. It remains unknown if sex modulates the appetite suppressant effect ... -
Investigation to identify individual socioeconomic and health determinants of suicidal ideation using responses to a cross-sectional, community-based public health survey
(Peer reviewed; Journal article, 2021)Abstract Objectives To address a gap in knowledge by simultaneously assessing a broad spectrum of individual socioeconomic and potential health determinants of suicidal ideation (SI) using validated measures in a large UK ... -
Ipilimumab in a real-world population: A prospective Phase IV trial with long-term follow-up
(Peer reviewed; Journal article, 2021)Ipilimumab was the first treatment that improved survival in advanced melanoma. Efficacy and toxicity in a real-world setting may differ from clinical trials, due to more liberal eligibility criteria and less intensive ... -
Irisin reduces orthodontic tooth movement in rats by promoting the osteogenic potential in the periodontal ligament
(Peer reviewed; Journal article, 2023)Objectives Positive effects of irisin on osteogenic differentiation of periodontal ligament (PDL) cells have been identified previously, this study aims to examine its effect on orthodontic tooth movement (OTM) in ... -
