Identification of metabolites in non-targeted metabolomics continues to be a bottleneck in metabolomics studies in large human cohorts. Unidentified metabolites frequently emerge in the results of association studies linking metabolite levels to, for example, clinical phenotypes. For further analyses these unknown metabolites must be identified. Current approaches utilize chemical information, suc

Objective: The glucose stimulation of insulin secretion (GSIS) by pancreatic β-cells critically depends on increased production of metabolic coupling factors, including NADPH. Nicotinamide nucleotide transhydrogenase (NNT) typically produces NADPH at the expense of NADH and δpH in energized mitochondria. Its spontaneous inactivation in C57BL/6J mice was previously shown to alter ATP production, Ca

Background The increasing prevalence of atrial fibrillation and novel therapeutic tools to prevent cardioembolic stroke has increased the need for risk markers. Objectives This study explored the relationship between the midregional sequence of pro-atrial natriuretic peptide (MR-proANP) levels with the risk of atrial fibrillation and stroke, and whether measurement of MR-proANP improves the predic

BACKGROUND The instantaneous wave-free ratio (iFR) is an index used to assess the severity of coronary-artery stenosis. The index has been tested against fractional flow reserve (FFR) in small trials, and the two measures have been found to have similar diagnostic accuracy. However, studies of clinical outcomes associated with the use of iFR are lacking. We aimed to evaluate whether iFR is noninfe

Background and aim Pain is common and adds to the global burden of disease. However, individuals suffering from pain are a heterogeneous group in terms of pain spreading, intensity and duration. While pain influences overall health care consultation not everyone with pain consult health care. To be able to provide health care matching the patients’ needs increased knowledge about what factors dete

Background: Colon capsule endoscopy (CCE) offers direct mucosal visualisation without sedation or gas insufflation required in conventional colonoscopy (CC). However, evidence for the role of CCE as an adjunct or alternative to CC remains equivocal. In this observational cohort study, we report our experience of using CCE to investigate patients with suspected colon pathology at a tertiary referra

Objective Invasive treatment of peripheral arterial disease (PAD) does not always lead to improvement, as concomitant diseases might affect walking ability and health related quality of life (HRQoL). Patients with chronic widespread pain (CWP) report worse outcome when treated for cancer and rheumatic diseases. The aim of the present study was to evaluate the prevalence of CWP and its potential as

Background and aims The pathogenesis of abdominal aortic aneurysm (AAA) shares several common pathways with atherosclerosis. Prospective clinical plasma biomarker studies in AAA have been hampered by the need for very large cohorts and long follow-up time. Methods We analyzed a prospective longitudinal cohort of middle-aged individuals from the cardiovascular cohort of the Malmö Diet and Cancer st

The totality of microbial genomes in the gut exceeds the size of the human genome, having around 500-fold more genes that importantly complement our coding potential. Microbial genes are essential for key metabolic processes, such as the breakdown of indigestible dietary fibres to short-chain fatty acids, biosynthesis of amino acids and vitamins, and production of neurotransmitters and hormones. D

Background Psychological stress is an independent risk factor for cardiovascular disease (CVD), but the mechanism by which stress is associated with CVD is not entirely understood. Although genetic factors are implied in both stress responsivity and cardiovascular reactivity, no studies to date have investigated their interactions with stress for cardiovascular end points. The objective was to elu

Limited data are available about the role of the serotonin 2B (5-HT2B) receptor in the function of human islets. This study aimed to test whether the 5-HT2B receptor contributes to glucose, insulin, and glucagon homeostasis in humans, utilizing a hereditary loss-of-function gene mutation in the receptor, which causes a 50% reduction in the production of the receptor protein in heterozygotes. This

Reality isn’t what it appears to be. Contexts are not always clear and visible. People don’t always say what they really mean. And they don’t always mean what they say. When life is your stage manager, anything can happen. I often say, life is hard, my head is harder. Making documentaries is not for the faint-hearted.This PhD project explores creative processes and parallel realities in documentar

oxLDL peptide vaccine and its antibody adoptive transferring have shown a significantly preventive or therapeutic effect in atherosclerotic animal model. The molecular mechanism behind this is obscure. Here, we report that oxLDL induces MCP-1 release in monocytes/macrophages through their TLR-4 (Toll-like receptor 4) and ERK MAPK pathway and is calcium/potassium channel-dependent. Using blocking a

Study Design. Descriptive register studyObjective. To describe preoperative levels of leg and back pain in patients operated for lumbar spinal stenosis and to obtain information on how three different pain constellations (back pain < leg leg pain, back pain > leg pain, back pain = leg pain) correlate to HRQoL and function in different morphological types of stenosis.Summary of Background Data. Deg

The aim of this study was to examine whether autoantibodies to: ZnT8-Tryptophan (ZnT8WA), ZnT8-Arginine (ZnT8RA) or ZnT8-Glutamine (ZnT8QA) correlated with C-peptide or other autoantibodies and to assess diagnostic sensitivity of ZnT8WRQA. Specimens from 270 newly diagnosed diabetic subjects (age 15--34 years) and after five 5 years duration of disease were examined. Four linear regression models

Background: Graves' ophthalmopathy (GO) and lymphedema share some pathogenetic mechanisms, such as edema, inflammation, and adipogenesis. The aim of this study was to examine similarities and differences between chronic GO and chronic lymphedema. Methods: Intraorbital adipose tissue was collected from patients with active (n = 10) or chronic GO (n = 10) and thyroid-healthy controls (n = 10). Arm s
