(Journal article; Peer reviewed, 2020)Introduction Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age and the leading cause of anovulatory infertility. Women with PCOS have a 15-fold higher prevalence of infertility, ... -
In children and adolescents with temporomandibular disorder assembled with juvenile idiopathic arthritis ‑ no association were found between pain and TMJ deformities using CBCT
(Peer reviewed; Journal article, 2021)Background Children and adolescents with juvenile idiopathic arthritis (JIA) may suffer from temporomandibular disorder (TMD). Due to this, imaging diagnosis is crucial in JIA with non-symptomatic TM joint (TMJ) involvement. ... -
In vivo 31P MRSI for metabolic profiling of human breast cancer xenografts
(Journal article; Peer reviewed, 2015)Purpose To study cancer associated with abnormal metabolism of phospholipids, of which several have been proposed as biomarkers for malignancy or to monitor response to anticancer therapy. We explored 3D 31P magnetic ... -
In vivo intracardiac vector flow imaging using phased array transducers for pediatric cardiology
(Journal article; Peer reviewed, 2017)Two-dimensional blood speckle tracking (ST) has shown promise for measuring complex flow patterns in neonatal hearts using linear arrays and high-frame-rate plane wave imaging. For general pediatric applications, however, ... -
In-hospital Cardiac Arrest Causes, Recognition and Survival
(Doctoral theses at NTNU;2016:99, Doctoral thesis, 2016)Hjertestans på sykehus – En studie av underliggende årsaker. Tre studier ligger til grunn for denne avhandlingen. I disse studiene har vi gransket årsakene til hjertestans som oppstår plutselig og uventet inne på sykehus. ... -
Incidence and risk factors for major bleeding among patients undergoing percutaneous coronary intervention: Findings from the Norwegian Coronary Stent Trial (NORSTENT)
(Peer reviewed; Journal article, 2021)Introduction Bleeding is a concern after percutaneous coronary intervention (PCI) and subsequent dual antiplatelet therapy (DAPT). We herein report the incidence and risk factors for major bleeding in the Norwegian Coronary ... -
Incidence of thrombotic complications in hospitalised and non-hospitalised patients after COVID-19 diagnosis
(Peer reviewed; Journal article, 2021)Infection with coronavirus disease-2019 (COVID-19) may predispose for venous thromboembolism (VTE). There is wide variation in reported incidence rates of VTE in COVID-19, ranging from 3% to 85%. Therefore, the true incidence ... -
Incidence, case fatality and long-term outcomes in patients with sepsis - Nationwide registry studies of sepsis and COVID-19-related sepsis
(Doctoral theses at NTNU;2024:36, Doctoral thesis, 2024)Sepsis is a severe immune reaction to an infection that leads to acute organ dysfunction and is a common cause of hospitalization, morbidity, and death. After surviving sepsis, many patients experience health impairments ... -
Incidence, recurring admissions and mortality of severe bacterial infections and sepsis over a 22-year period in the population-based HUNT study
(Peer reviewed; Journal article, 2022)Purpose Severe bacterial infections are important causes of hospitalization and loss of health worldwide. In this study we aim to characterize the total burden, recurrence and severity of bacterial infections in the ... -
