- PPIs (Proton-pump inhibitors) offers the best treatment for acid related diseases. The predominant indications for PPI prescription are:GERDeradication of H. pylori-infection in combination with antibioticsH. pylori-negative peptic ulcer healing of and prophylaxis against NSAID/COXIB--induced gastroduodenal lesions acid hypersecretory states such as Zollinger-Ellisons syndrome.The market for PPIs continues to expand in most countries. A significant over- and misuse of PPIs prevails in hospital care as well as in general practice. The predominant reasons for and mechanisms behind the over- and misuse of PPIs are well recognised. The most important consequences of this overprescription of PPIs are increasing medical costs and risk for long-term adverse side effects. Continued education and dedicated information are key factors to guide physicians, medical personnel and patients to adopt to generally accepted principles for and balanced use of PPIs.

Antibodies to a Citrullinated Porphyromonas gingivalis Epitope Are Increased in Early Rheumatoid Arthritis, and Can Be Produced by Gingival Tissue B Cells : Implications for a Bacterial Origin in RA Etiology
- 2022

In: Frontiers in Immunology. - : Frontiers Media S.A.. - 1664-3224. ; 13
-
Journal article (peer-reviewed)abstract
- Based on the epidemiological link between periodontitis and rheumatoid arthritis (RA), and the unique feature of the periodontal bacterium Porphyromonas gingivalis to citrullinate proteins, it has been suggested that production of anti-citrullinated protein antibodies (ACPA), which are present in a majority of RA patients, may be triggered in the gum mucosa. To address this hypothesis, we investigated the antibody response to a citrullinated P. gingivalis peptide in relation to the autoimmune ACPA response in early RA, and examined citrulline-reactivity in monoclonal antibodies derived from human gingival B cells. Antibodies to a citrullinated peptide derived from P. gingivalis (denoted CPP3) and human citrullinated peptides were analyzed by multiplex array in 2,807 RA patients and 372 controls; associations with RA risk factors and clinical features were examined. B cells from inflamed gingival tissue were single-cell sorted, and immunoglobulin (Ig) genes were amplified, sequenced, cloned and expressed (n=63) as recombinant monoclonal antibodies, and assayed for citrulline-reactivities by enzyme-linked immunosorbent assay. Additionally, affinity-purified polyclonal anti-cyclic-citrullinated peptide (CCP2) IgG, and monoclonal antibodies derived from RA blood and synovial fluid B cells (n=175), were screened for CPP3-reactivity. Elevated anti-CPP3 antibody levels were detected in RA (11%), mainly CCP2+ RA, compared to controls (2%), p<0.0001, with a significant association to HLA-DRB1 shared epitope alleles, smoking and baseline pain, but with low correlation to autoimmune ACPA fine-specificities. Monoclonal antibodies derived from gingival B cells showed cross-reactivity between P. gingivalis CPP3 and human citrullinated peptides, and a CPP3+/CCP2+ clone, derived from an RA blood memory B cell, was identified. Our data support the possibility that immunity to P. gingivalis derived citrullinated antigens, triggered in the inflamed gum mucosa, may contribute to the presence of ACPA in RA patients, through mechanisms of molecular mimicry.

Broadening risk profile in familial colorectal cancer type X; Increased risk for five cancer types in the national Danish cohort
- 2020
-
In: BMC Cancer. - : Springer Science and Business Media LLC. - 1471-2407. ; 20:1
-
Journal article (peer-reviewed)abstract
- Background: Familial colorectal cancer type X (FCCTX) is a phenotypically defined subset of hereditary colorectal cancer with unknown and potentially heterogeneous genetic aetiology. FCCTX has been characterized as a colorectal cancer-specific syndrome, which we herein challenge by estimating the risk for extra-colorectal cancer in the Danish FCCTX cohort. Methods: Through the national hereditary non-polyposis colorectal cancer (HNPCC) register, 213 families fulfilling the Amsterdam I criteria and showing retained mismatch repair (MMR) function were identified. In here, sex and age-specific incidence rate ratios (IRR) were calculated for 30 extra-colorectal cancer types in comparison with the general Danish population. Results: In total, 494 extra-colorectal cancers developed with significantly increased risks for cancers of the urinary tract, breast, stomach, pancreas, and eye tumours. The age groups at increased risks were 30-49 years for gastric cancer, 30-69 years for female breast cancer, 50-69 years for ocular melanoma and above age 70 for pancreatic cancer and urothelial cancer. Conclusions: Danish FCCTX families show an increased risk of several extra-colorectal cancer types. This observation may indicate unidentified disease-predisposing genetic variants in this phenotypically defined subset of hereditary colorectal cancer and calls for awareness during genetic counselling and follow-up.

Unpacking Nordic branding : the value regimes of Nordicness
- 2021
-
In: Journal of Place Management and Development. - 1753-8335 .- 1753-8343. ; 14:3, s. 362-378
-
Journal article (peer-reviewed)abstract
- PurposeThis paper aims to develop place branding theory toward the accommodation of a multifaceted understanding of value and value negotiation by Nordic branding actors by way of answering the following question: How is Nordicness appropriated by Nordic branding actors and what value regimes are drawn on in the process?Design/methodology/approachUsing field data from a selection of branding actors and sectors in Norway, Sweden and Denmark, a qualitative analysis of Nordic branding performances is used to unpack the negotiations of valuation of worth.FindingsThe analysis identified three principle orders of worth behind Nordicness (civic, green and inspired) that are negotiated through compromises between orders of industry and domestic and by contesting the orders of fame and market. The findings indicate how Nordicness is performed as principle worths and tensions and how these are rendered meaningful as propositions of “value as difference” as they are performed in practice by brand actors.Originality/valueSeveral studies focus on how place branding “adds value;” however, few studies have been aimed at unpacking how a “value universe” is negotiated as a more complex understanding of worth or “value.” This study thus opens up for branding heterogeneity, which signifies awareness of competing notions and orders of worth among small- and medium-sized enterprises and other central stakeholders; this could further inspire interdisciplinary, value-based research into the potential contingencies of (product) branding and place branding in other contexts and regions.

Evening chronotype is associated with elevated biomarkers of cardiometabolic risk in the EpiHealth cohort: a cross-sectional study
- 2022
-
In: Sleep. - : Oxford University Press. - 0161-8105 .- 1550-9109. ; 45:2
-
Journal article (peer-reviewed)abstract
- Study objectives: Individuals with evening chronotype have a higher risk of cardiovascular and metabolic disorders, although the underlying mechanisms are not well understood. In a population- based cohort, we aimed to investigate the association between chronotype and 242 circulating proteins from three panels of established or candidate biomarkers of cardiometabolic processes. Methods: In 2,471 participants (49.7% men, mean age 61.2±8.4 SD years) from the EpiHealth cohort, circulating proteins were analyzed with a multiplex proximity extension technique. Participants self- reported their chronotype on a five-level scale from extreme morning to extreme evening chronotype. With the intermediate chronotype set as the reference, each protein was added as the dependent variable in a series of linear regression models adjusted for confounders. Next, the chronotype coefficients were jointly tested and the resulting p-values adjusted for multiple testing using false discovery rate (5%). For the associations identified, we then analyzed the marginal effect of each chronotype category. Results: We identified 17 proteins associated with chronotype. Evening chronotype was positively associated with proteins previously linked to insulin resistance and cardiovascular risk, namely retinoic acid receptor protein 2, fatty acid-binding protein adipocyte, tissue-type plasminogen activator, and plasminogen activator inhibitor 1 (PAI-1). Additionally, PAI-1 was inversely associated with the extreme morning chronotype. Conclusions: In this population-based study, proteins previously related with cardiometabolic risk were elevated in the evening chronotypes. These results may guide future research in the relation between chronotype and cardiometabolic disorders.

OSA Is Associated With the Human Gut Microbiota Composition and Functional Potential in the Population-Based Swedish CardioPulmonary bioImage Study
- 2023
-
In: Chest. - : Elsevier. - 0012-3692 .- 1931-3543. ; 164:2, s. 503-516
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Obstructive sleep apnea (OSA) is a common sleep-breathing disorder linked to increased risk of cardiovascular disease. Intermittent hypoxia and intermittent airway obstruction, hallmarks of OSA, have been shown in animal models to induce substantial changes to the gut microbiota composition and subsequent transplantation of fecal matter to other animals induced changes in blood pressure and glucose metabolism.RESEARCH QUESTION: Does obstructive sleep apnea in adults associate with the composition and metabolic potential of the human gut microbiota?STUDY DESIGN AND METHODS: We used respiratory polygraphy data from up to 3,570 individuals aged 50-64 from the population-based Swedish CardioPulmonary bioImage Study combined with deep shotgun metagenomics of fecal samples to identify cross-sectional associations between three OSA parameters covering apneas and hypopneas, cumulative sleep time in hypoxia and number of oxygen desaturation events with gut microbiota composition. Data collection about potential confounders was based on questionnaires, on-site anthropometric measurements, plasma metabolomics, and linkage with the Swedish Prescribed Drug Register.RESULTS: We found that all three OSA parameters were associated with lower diversity of species in the gut. Further, the OSA-related hypoxia parameters were in multivariable-adjusted analysis associated with the relative abundance of 128 gut bacterial species, including higher abundance of Blautia obeum and Collinsela aerofaciens. The latter species was also independently associated with increased systolic blood pressure. Further, the cumulative time in hypoxia during sleep was associated with the abundance of genes involved in nine gut microbiota metabolic pathways, including propionate production from lactate. Lastly, we observed two heterogeneous sets of plasma metabolites with opposite association with species positively and negatively associated with hypoxia parameters, respectively.INTERPRETATION: OSA-related hypoxia, but not the number of apneas/hypopneas, is associated with specific gut microbiota species and functions. Our findings lay the foundation for future research on the gut microbiota-mediated health effects of OSA.

Severe alpha-1-antitrypsin deficiency increases the risk of venous thromboembolism
- 2021
-
In: Journal of Thrombosis and Haemostasis. - : John Wiley & Sons. - 1538-7933 .- 1538-7836. ; 19:6, s. 1519-1525
-
Journal article (peer-reviewed)abstract
- Background: Severe alpha-1-antitrypsin deficiency (AATD), phenotype PiZZ, is associated with increased risk of liver disease and chronic obstructive pulmonary disease (COPD), but the risk of venous thromboembolism (VTE) is unknown. Our aim was to evaluate the risk of VTE in individuals with severe AATD compared with control subjects from the general population.Methods: Individuals with severe AATD (n = 1577) were recruited from the Swedish national AATD register. Control subjects (n = 5969) were selected from the OLIN (Obstructive Lung Disease in Northern Sweden) studies, that include a random general population sample. Longitudinal data on VTE and diagnoses were obtained from the Swedish National Patient Registry. Associations were analyzed using multivariable Cox regression.Results: At inclusion, 46% of the AATD individuals and 53% of the controls were never-smokers. COPD was present in 46% of the AATD individuals compared with 4% of the controls. During a median follow-up of 18 years, 116 (7%) of the AATD individuals and 89 (1%) of the control subjects developed VTE, unadjusted hazard ratio 6.5 (95% confidence interval 4.9–8.6). Risk factors for incident VTE were male gender, age, COPD, cancer, and liver disease. Adjusting for these factors, the AATD individuals had a significantly higher risk of incident VTE, adjusted hazard ratio 4.2 (95% confidence interval 2.9–6.2) as compared with the controls.Conclusion: Subjects with severe AATD have considerably increased risk of developing VTE compared with the general population, even after accounting for risk factors. This calls for optimized risk factor management and clinical follow-up of this patient group.

Sinonasal outcome test-22 and peak nasal inspiratory flow : valuable tools in obstructive sleep apnoea
- 2020
-
In: Rhinology. - 0300-0729 .- 1996-8604. ; 58:4, s. 341-348
-
Journal article (peer-reviewed)abstract
- Background: Sinonasal complaints contribute to low adherence to continuous positive airway pressure (CPAP) treatment. We aimed to investigate sinonasal health in obstructive sleep apnoea (OSA) patients, using the sinonasal outcome test-22 (SNOT-22), and to analyse whether SNOT-22 is affected by CPAP adherence. We also aimed to investigate whether peak nasal inspiratory flow (PNIF) was able to predict adherence to CPAP. Methods:The study population comprised 197 OSA patients (60 females) initiating CPAP treatment The SNOT-22, PNIF and the Epworth Sleepiness Scale were assessed at baseline and follow-up. One-night polygraphy, the Hospital Anxiety and Depression Scale, peak expiratory flow and health-related issues were assessed at baseline. At follow-up, the patients were categorised into adherent (>4 hours/night) and non-adherent (<4 hours/night) to CPAP treatment. Results: The average time for following up CPAP treatment was (mean +/- SD) 24.0 +/- 23.9 days and it did not differ significantly between the groups.The SNOT-22 score was elevated among all OSA patients, 36.1 +/- 19.4.There was a larger improvement in the SNOT-22 score at follow-up among adherent CPAP users compared with non-adherent users (-10.4 +/- 13.9 vs. -3.2 +/- 15.4). A PNIF value of < 100 litres/min increased the risk of non-adherence to CPAP with an adjusted odds ratio (OR) of 2.40 ((95% CI 1.16-5.00)). Conclusions: The SNOT-22 was elevated in patients with OSA, indicating a considerable sinonasal disease burden.The SNOT-22 improved with good CPAP adherence. A low PNIF value was able to predict poor CPAP adherence. Both the SNOT-22 and PNIF can be valuable tools in the evaluation of OSA patients and in the management of CPAP treatment.
