  • Validation of serrated polyps (SPs) in Swedish pathology registers
  • 2019
  • Ingår i: BMC Gastroenterology. - : BMC. - 1471-230X. ; 20:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Little is known about the natural history of serrated polyps (SPs), partly due to the lack of large-scale epidemiologic data. In this study, we examined the validity of SP identification according to SNOMED (Systematised Nomenclature of Medicine) codes and free text from colorectal histopathology reports.Methods: Through the ESPRESSO (Epidemiology Strengthened by histoPathology Reports in Sweden) study, we retrieved data on SPs from all pathology departments in Sweden in 2015-2017 by using SNOMED codes and free-text search in colorectal histopathology reports. Randomly selected individuals with a histopathology report of SPs were validated against patient charts using a structured, retrospective review.Results: SPs were confirmed in 101/106 individuals with a histopathology report of SPs, yielding a positive predictive value (PPV) of 95% (95%CI = 89-98%). By year of diagnosis, the PPV was 89% (95%CI = 69-97%), 96% (95%CI = 81-99%) and 97% (95%CI = 89-99%) for individuals diagnosed before 2001 (n = 19), between 2001 and 2010 (n = 26) and after 2010 (n = 61), respectively. According to search method, the PPV for individuals identified by SNOMED codes was 100% (95%CI = 93-100%), and 93% (95%CI = 86-97%) using free-text search. Recorded location (colon vs. rectum) was correct in 94% of all SP histopathology reports (95%CI = 84-98%) identified by SNOMED codes. Individuals with SPs were classified into hyperplastic polyps (n = 34; 32%), traditional serrated adenomas (n = 3; 3%), sessile serrated adenomas/polyps (SSA/Ps) (n = 70; 66%), unspecified SPs (n = 3, 3%), and false positive SPs (n = 5, 5%). For individuals identified by SNOMED codes, SSA/Ps were confirmed in 49/52 individuals, resulting in a PPV of 94% (95%CI: 84-98%). In total, 57% had >= 2 polyps (1: n = 44, 2-3: n = 33 and >= 4: n = 27). Some 46% of SPs (n = 71) originated from the proximal colon and 24% were >= 10 mm in size (n = 37). Heredity for colorectal cancer, intestinal polyposis syndromes, or both was reported in seven individuals (7%). Common comorbidities included diverticulosis (n = 45, 42%), colorectal cancer (n = 19, 18%), and inflammatory bowel disease (n = 10, 9%).Conclusion: Colorectal histopathology reports are a reliable data source to identify individuals with SPs.

  • The In Vivo Fate of Polycatecholamine Coated Nanoparticles Is Determined by a Fibrinogen Enriched Protein Corona
  • 2023
  • Ingår i: ACS Nano. - 1936-086X .- 1936-0851. ; 17:24, s. 24725-24742

    • Polycatecholamine coatings have attracted significant attention in the past 10 years owing to their ability to functionalize a wide range of materials. Here we apply the use of such coatings to drug nanocrystals, made from a poorly soluble drug compound, to postfunctionalize the nanocrystal surface with the aim of providing steric stabilization and extending their circulation time after intravenous injection. We show that both polydopamine and polynorepinephrine can be used to successfully modify drug nanocrystals and subsequently incorporate end-functionalized PEG to the surface. Even though high grafting densities of PEG were achieved, we observed rapid clearance and increased liver uptake for polycatecholamine functionalized drug nanocrystals. Using both surface sensitive model systems and protein corona profiling, we determine that the rapid clearance was correlated with an increase in adsorption of proteins involved in coagulation to the polycatecholamine surface, with fibrinogen being the most abundant. Further analysis of the most abundant proteins revealed a significant increase in thiol-rich proteins on polycatecholamine coated surfaces. The observed interaction with coagulation proteins highlights one of the current challenges using polycatecholamines for drug delivery but might also provide insights to the growing use of these materials in hemostatic applications.

  • Autoimmune Disease in First-Degree Relatives and Spouses of Individuals With Celiac Disease
  • 2015
  • Ingår i: Clinical Gastroenterology and Hepatology. - : Elsevier BV. - 1542-3565 .- 1542-7714. ; 13:7, s. 1271-1277.e2
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND & AIMS: First-degree relatives of individuals with celiac disease are at increased risk for this disorder, but little is known about their risk for other autoimmune diseases. We assessed the risk of nonceliac autoimmune disease in first-degree relatives and spouses of people with celiac disease. METHODS: We identified individuals with celiac disease by searching computerized duodenal and jejunal biopsies, collected from 1969 through 2008, at 28 pathology departments in Sweden. Celiac disease was identified based on biopsy reports of villous atrophy (equal to Marsh grade 3; n = 29,096). Individuals with celiac disease were matched with up to 5 controls (people without celiac disease) for sex, age, county, and calendar year (total, 144,522 controls). Through Swedish health care registries, we identified all first-degree relatives (fathers, mothers, siblings, and offspring) and spouses of individuals with celiac disease (n = 84,648) and controls (n = 430,942). We used Cox regression analysis to calculate hazard ratios (HRs) for nonceliac autoimmune disease (Crohn's disease, type 1 diabetes mellitus, hypothyroidism, hyperthyroidism, psoriasis, rheumatoid arthritis, sarcoidosis, systemic lupus erythematosus, or ulcerative colitis) in these groups. RESULTS: During the follow-up period (median, 10.8 y), 3333 of the first-degree relatives of patients with celiac disease (3.9%) and 12,860 relatives of controls (3.0%) had an autoimmune disease other than celiac disease. First-degree relatives of people with celiac disease were at increased risk of nonceliac autoimmune disease, compared with controls (HR, 1.28; 95% confidence interval, 1.23-1.33), as were spouses (HR, 1.20; 95% confidence interval, 1.06-1.35). Risk estimates for nonceliac autoimmune disease did not differ between first-degree relatives and spouses of individuals with celiac disease (interaction test: P =.11). HRs for nonceliac autoimmune disease were highest in the first 2 years of follow-up evaluation. CONCLUSIONS: First-degree relatives and spouses of individuals with celiac disease are at increased risk of nonceliac autoimmune disease. In addition to genetic factors, environmental factors and ascertainment bias might contribute to the increased risk of autoimmunity in first-degree relatives of individuals with celiac disease.

  • Cardiac complications in celiac disease
  • 2013
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Background: Celiac disease (CD) is an immune-mediated enteropathy induced by dietary gluten that affects about 1% of western populations. CD has been associated to an increased risk of cardiovascular mortality in some studies; however associations to cardiovascular diseases have not been broadly researched.Aim: The aim of this thesis was to examine the associations between CD and some cardiovascular diseases, namely; atrial fibrialltion, dilated cardiomyopathy and risk factors of ischemic heart disease.Methods: We used computerized data on all Swedish patients with biopsy-verified CD equal to villous atrophy from 1969 to 31st of December 2008. All CD patients were matched on age, sex, county and calendar year with up to five reference individuals. Altogether we had data on 29,096 CD patients and 144,522 reference individuals. Data were linked to different Swedish national registries and the Swedish quality and cardiac care registry SWEDEHEART. Main outcomes in the studies were: I: atrial fibrillation registered in the national patient registry or the cause of death registry, II: chart validated idiopathic dilated cardiomyopathy, III: different risk factors, clinical presentation and parameters in patients with first myocardial infarction (MI) registered in SWEDEHEART and IV: follow-up parameters, 6-10 weeks and one year after MI, registered in SWEDEHEART.Result: We showed a 34% increased risk of atrial fibrillation in CD and a 73% increased risk of dilated cardiomyopathy, the latter only of borderline significance, p=0.052. In the third study we showed that CD patients with MI had a more beneficial cardiovascular risk factor profile, better left ventricular ejection fraction and fewer stenoses on coronary angiography compared to reference individuals with MI. The fourth study showed that follow-up after MI does not differ from follow-up in reference individuals.Conclusion: This thesis supports an association of cardiovascular diseases in CD. Potential mechanisms include shared risk factors and chronic in-flammation.

  • Cardiovascular disease in patients with coeliac disease : A systematic review and meta-analysis
  • 2015
  • Ingår i: Digestive and Liver Disease. - : Elsevier BV. - 1590-8658 .- 1878-3562. ; 47:10, s. 847-852
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Coeliac disease has been associated with an increased risk of cardiovascular disease in some studies, whereas other studies have shown no association. We performed a systematic review and meta-analysis of cardiovascular disease in celiac disease. Methods: Pubmed, Cinahl, EMBASE and Medline via Ovid were searched for relevant articles published until January 5, 2015. English-language articles on studies with more than 20 patients were included, and were quality rated using the GRADE risk of bias tool. We used random-effects models and assessed heterogeneity using the I-2 statistic. Results: Ten studies were relevant, reporting the risk of myocardial infarction, cardiovascular death and stroke in 33,128/32,903/32,466 coeliac disease patients respectively. Only one study examined celiac disease and a composite measure of cardiovascular disease and this study found a hazard ratio of 1.10 (95% CI 1.03-1.28). In a meta-analysis, we observed an increased risk of stroke (OR 1.11; 95% CI 1.02-1.20). The risks of myocardial infarction (OR 1.12; 95% CI 0.83-1.40) and cardiovascular death (OR 1.12; 95% CI 0.96-1.29) were similar but were estimated with less certainty. Heterogeneity was low for all outcomes except for myocardial infarction where it was moderate. Conclusion: Coeliac disease was associated with a modestly increased risk of cardiovascular disease, but the evidence base is limited.

  • Colorectal cancer death after adenoma removal in Scandinavia
  • 2017
  • Ingår i: Scandinavian Journal of Gastroenterology. - Oxfordshire, United Kingdom : Taylor & Francis. - 0036-5521 .- 1502-7708. ; 52:12, s. 1377-1384
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: Improved understanding of the subsequent risk death from colorectal cancer (CRC) among individuals who had adenomas removed is needed. We aimed to quantify this risk using prospectively collected data from population-based cohorts.MATERIALS AND METHODS: Using Norwegian and Swedish registries, a cohort of 90,864 individuals with colorectal adenomas removed between 1980 and 2013 was identified. Surveillance was only recommended for high-risk adenomas. The validity of the registry data did not allow classification into low- and high-risk adenomas. Virtually complete follow-up was achieved through linkage to nationwide registers. We calculated incidence-based standardised mortality ratios (SMRs) with 95% confidence intervals (CI).RESULTS: The median follow-up was 7.2 years; 48,058 individuals were followed for more than 10 years. We observed 819 deaths (0.9%) from CRC and expected 731 CRC deaths (0.8%), corresponding to an absolute excess risk of 88 cases (0.1%) and a relative risk of 12% (SMR 1.12; 95%CI 1.05-1.20). The relative risk of CRC death following adenoma removal was slightly higher in Sweden (SMR 1.22; 95%CI 1.11-1.34) than in Norway (SMR 1.03; 95%CI 0.93-1.14), and higher in women (SMR 1.24; 95%CI 1.12-1.36) than in men (SMR 1.02; 95%CI 0.93-1.13). Among individuals with more than 10 years of follow-up, the estimates were similar to the overall cohort, absolute excess risk 0.1% (SMR 1.15; 95%CI 1.06-1.24).CONCLUSION: The excess risk of CRC death following adenoma removal is small. Optimal surveillance recommendations should be tested in randomised trials.

  • Follow-up of ischaemic heart disease in patients with coeliac disease
  • 2015
  • Ingår i: European Journal of Preventive Cardiology. - London, United Kingdom : Sage Publications. - 2047-4873 .- 2047-4881. ; 22:1, s. 83-90
  • Tidskriftsartikel (refereegranskat)abstract
    • Patients with coeliac disease and myocardial infarction have a more favourable atherosclerotic risk factor profile than controls with myocardial infarction (MI). Therefore, MI prognosis and treatment may differ according to coeliac status. This paper reports on the study of Swedish MI patients with and without coeliac disease (equal to villous atrophy; Marsh histopathology stage 3) based on duodenal or jejunal biopsy data. We used the Swedish Quality Register (SWEDEHEART) to identify individuals with a record of MI from 2005 to 2008 and to obtain data on medication, coronary interventions, and clinical and laboratory parameters at 6–10 weeks and one year after first MI. One-year mortality and coronary interventions were assessed for 430 coeliac patients and 1988 controls. For other outcome variables, we compared 42 coeliac patients with MI and 201 general population controls with MI. Odds ratios (ORs) were calculated by logistic regression. The results showed that compared with controls with MI, coeliac individuals with MI had significantly higher one-year all-cause mortality (OR = 1.43; 95% confidence interval (CI) = 1.04–1.95) but less often underwent a percutaneous coronary intervention (OR = 0.77; 95% CI = 0.61–0.96). Coeliac patients were more often prescribed warfarin but less often aspirin and statins. The readmission rate due to cardiac events in coeliac patients was 15.2% vs. 12.6% in controls (p-value  = 0.69). Other clinical and laboratory parameters were similar. We conclude that the follow up of MI does not seem to differ between coeliac patients and controls, and is unlikely to explain the excess mortality from cardiovascular disease noted in Swedish patients with CD.

  • Gall Bladder Disease and the Risk of Small Bowel Cancer : Results from a Nationwide Swedish Cohort Study
  • 2022
  • Ingår i: Cancers. - : MDPI. - 2072-6694. ; 14:3
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND AND AIMS: Small bowel cancer is a rare but rising malignancy. The etiology is poorly understood and there is a need for large-scale studies. Gallbladder disease (GBD), inducing localized inflammation, has been suggested to increase small bowel cancer risk.METHODS: We retrieved nationwide data from Sweden's 28 pathology departments on all adults (age 20-79) with pathology-confirmed GBD diagnosed in 1965-2017. In total 156,390 GBD patients were matched with up to 5 matched comparators from the general population and follow-up started one year after GBD diagnosis. We used stratified Cox regression to calculate hazard ratios (HRs) for small bowel adenocarcinoma, adenomas, and carcinoids.RESULTS: During a median follow-up of 12 years, we identified 92 small bowel adenocarcinomas, 132 adenomas, and 81 carcinoid tumors in the GBD cohort. Corresponding incidence rates were 4.8, 6.9, and 4.2 per 100,000 person-years (PY), compared to 3.2, 3.2, and 1.8 in matched comparators. The adjusted HR was 1.42 (95% CI = 1.08-1.87) for small bowel adenocarcinoma, 1.79 (95% CI = 1.41-2.27) for adenoma, and 2.07 (95% CI = 1.52-2.81) for carcinoid. The excess cancer risk was most pronounced during the first year of follow-up for adenocarcinomas and during the first six years for adenomas while for carcinoids the HR peaked 10-15 years after start of follow-up.CONCLUSIONS: In this nationwide cohort study, GBD was associated with an increased risk of small bowel cancer. The excess risk of small bowel adenocarcinoma was mainly seen during the first years of follow-up while small bowel carcinoid risk peaked 11-16 years after GBD diagnosis.

  • Increased risk of atrial fibrillation in patients with coeliac disease : a nationwide cohort study
  • 2011
  • Ingår i: European Heart Journal. - Oxford, United Kingdom : Oxford University Press. - 0195-668X .- 1522-9645. ; 32:19, s. 2430-7
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: Inflammatory markers are established risk factors for atrial fibrillation (AF), but the role of autoimmune diseases is unknown. The aim of the study was to examine the association between coeliac disease (CD) and AF in a large cohort of patients with biopsy-verified CD.Metods and results: We identified 28,637 patients with CD through biopsy reports (defined as Marsh 3: villous atrophy) from all pathology departments (n = 28) in Sweden. Biopsies had been performed between 1969 and 2008. Age- and sex-matched reference individuals (n = 141,731) were identified from the Swedish Total Population Register. Data on AF were obtained from the Swedish Hospital Discharge Register, the Hospital Outpatient Register, and the Cause of Death Register. Hazard ratios (HRs) for AF were estimated using Cox regression. In the CD cohort, 941 individuals developed AF (vs. 2918 reference individuals) during a median follow-up of 9 years. The corresponding adjusted HR for AF was 1.34 (95% CI = 1.24-1.44). The absolute risk of AF in CD was 321 of 100,000 person-years, with an excess risk of 81 of 100,000. A prior AF diagnosis was also associated with an increased risk of subsequent CD (odds ratio = 1.45, 95% CI = 1.31-1.62).Conclusions Atrial fibrillation is more common both before and after CD diagnosis in patients with CD though the excess risk is small. Potential explanations for the increased risk of AF in CD include chronic inflammation and shared risk factors, but ascertainment bias may also have contributed.CLINICAL IMPLICATIONS: Coeliac disease affects 1-2% of the Western population. Our results indicate that patients with coeliac disease, verified by intestinal biopsy, are at increased risk of atrial fibrillation. This observation is consistent with previous findings that elevation of inflammatory markers predicts atrial fibrillation. Additional studies are needed to clarify the mechanistic link between atrial fibrillation and autoimmune diseases such as coeliac disease.

  • Ischaemic heart disease in first-degree relatives to coeliac patients
  • 2014
  • Ingår i: European Journal of Clinical Investigation. - Hoboken : Wiley-Blackwell. - 0014-2972 .- 1365-2362. ; 44:4, s. 359-364
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Coeliac disease (CD) has been linked to an increased risk of ischaemic heart disease (IHD). We examined the risk of IHD in first-degree relatives and spouses to coeliac patients to ascertain the genetic contribution to IHD excess risk.Study design and setting: Coeliac disease was defined as having a biopsy-verified villous atrophy (Marsh grade 3) in 1969-2008 (n=29096). Coeliac patients were matched to 144522 controls. Through Swedish registers, we identified all first-degree relatives and spouses to coeliac patients and their controls, in total 87622 unique coeliac relatives and 432655 unique control relatives. Our main outcome measure was IHD defined according to relevant international classification of disease codes in the Swedish Inpatient Registry or in the Cause of Death Registry. Hazard ratios (HR) and confidence intervals (CI) were estimated through Cox regression adjusted for sex, age-group and calendar year at study entry of the relative.Result: During a median follow-up of 108 years, 2880 coeliac relatives and 13817 control relatives experienced IHD. First-degree relatives of coeliac patients were at increased risk of IHD (HR=105; 95% CI=100-109, P-value=004), while spouses were at no increased risk (HR=099; 95% CI=087-112). The excess risk of IHD in coeliac first-degree relatives aged 40-59years was 70/100000 person-years.Conclusion: First-degree relatives to coeliac patients seem to be at an increased risk of IHD but the excess risk is so small that it has little clinical relevance.

  • Mortality in small bowel cancers and adenomas : A nationwide, population-based matched cohort study
  • 2023
  • Ingår i: Cancer Epidemiology. - : Elsevier. - 1877-7821 .- 1877-783X. ; 85
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Small bowel adenocarcinoma (SBA), neuroendocrine tumors (NET) and gastrointestinal stromal tumors (GIST) are neoplastic lesions of the small bowel while small bowel adenomas are precursors of SBA.Aim: To examine mortality in patients diagnosed with SBA, small bowel adenomas, NET and GIST.Methods: We performed a population-based matched cohort study encompassing all individuals with SBA (n = 2289), adenomas (n = 3700), NET (n = 1884) and GIST (n = 509) in the small bowel diagnosed at any of Sweden's 28 pathology departments between 2000 and 2016 (the "ESPRESSO study"). Each case was matched by sex, age, calendar year and county of residence to up to 5 comparators from the general population. Through Cox regression we estimated hazard ratios (HRs) and 95% confidence intervals (95%CIs) for death and cause-specific death adjusting for education.Results: During follow-up until December 31, 2017, 1836 (80%) deaths occurred in SBA patients, 1615 (44%) in adenoma, 866 (46%) in NET and 162 (32%) in GIST patients. This corresponded to incidence rates of 295, 74, 80 and 62/1000 person-years respectively and adjusted HRs of 7.60 (95%CI=6.95-8.31), 2.21 (2.07-2.36), 2.74 (2.50-3.01) and 2.33 (1.90-2.87). Adjustment for education had a substantial impact on the HR for death in SBA but not for other neoplasias. The predominant cause of excess death was cancer in all groups.Conclusion: This study confirms earlier findings of increased death rates in patients with SBA and NET in a modern study population. We also demonstrate a more than 2-fold increased risk of death in both GIST and the SBA precursor adenoma.

  • Mucosal healing and the risk of serious infections in patients with celiac disease
  • 2018
  • Ingår i: United European Gastroenterology journal. - : Sage Publications. - 2050-6406 .- 2050-6414. ; 6:1, s. 55-62
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Patients with celiac disease (CD) are at increased risk of certain infections, but it is unknown if mucosal healing influences this risk.Methods: We collected data on 29,096 individuals with CD (equal to villous atrophy) through Sweden's 28 pathology departments undergoing biopsy 1969-2008. Through the Swedish Patient Register we obtained information on any infection and specifically sepsis, streptococcal infection, influenza, Clostridium difficile, herpes zoster and pneumococcal infection up until December 2009. We used Cox regression to calculate hazard ratios (HRs) for the risk of future diagnosis of infection according to mucosal healing on follow-up biopsy (persistent villous atrophy vs mucosal healing).Results: Of 5598 CD individuals with no record of any infections before follow-up biopsy, 45% had persistent villous atrophy, 619 (24%) of them had a later infection, compared to 579 (19%) in those with mucosal healing (p<0.01); the yearly incidence was 2.1% in both groups. Adjusting for age, sex, calendar period, time between biopsies and education, persistent villous atrophy was however not associated with later infection overall (HR=0.99; 95% CI=0.88-1.11) or with any of the specific infections.Conclusions: In CD, mucosal healing does not influence the risk of serious infection requiring hospital-based medical attention.

  • No increased mortality in 109,000 first-degree relatives of celiac individuals
  • 2016
  • Ingår i: Digestive and Liver Disease. - : Elsevier. - 1590-8658 .- 1878-3562. ; 48:4, s. 376-380
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Several studies have shown an excess mortality in individuals with celiac disease (CD). However, it is unknown if also first-degree relatives (FDRs) to celiac patients are at increased risk of death. Aim: We aimed to assess mortality in FDRs to celiac patients. Methods: Individuals with CD were identified through biopsy reports (equal to Marsh grade III). Each celiac individual was matched on sex, age, county and calendar year with up to five control individuals. Through Swedish healthcare registries we identified all FDRs (father, mother, sibling, offspring) of CD individuals and controls. Through Cox regression we calculated hazard ratios (HRs) for mortality (all-cause death, circulatory, cancer and other). Results: We identified 109,309 FDRs of celiac individuals and 549,098 FDRs of controls. Overall mortality was increased in FDRs to celiac individuals (HR = 1.02, 95%CI = 1.00-1.04, p = 0.03). This corresponded to an excess risk of 5.9 deaths per 100,000 person-years of follow-up. When limiting follow-up to time since celiac diagnosis in the index individual, we found no increased risk of death (HR = 1.01; 95%CI = 0.98-1.03). Conclusion: FDRs to individuals with CD are at increased risk of death. This excess risk is however minimal and unlikely to be of any clinical importance to the individual.

  • Review of 103 Swedish healthcare quality registries
  • 2015
  • Ingår i: Journal of Internal Medicine. - : Wiley-Blackwell. - 0954-6820 .- 1365-2796. ; 277:1, s. 94-136
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and objectives: In the past two decades, an increasing number of nationwide, Swedish Healthcare Quality Registries (QRs) focusing on specific disorders have been initiated, mostly by physicians. Here, we describe the purpose, organization, variables, coverage and completeness of 103 Swedish QRs.Methods: From March to September 2013, we examined the 2012 applications of 103 QRs to the Swedish Association of Local Authorities and Regions (SALAR) and also studied the annual reports from the same QRs. After initial data abstraction, the coordinator of each QR was contacted at least twice between June and October 2013 and asked to confirm the accuracy of the data retrieved from the applications and reports.Results: About 60% of the QRs covered 80% of their target population (completeness). Data recorded in Swedish QRs include aspects of disease management (diagnosis, clinical characteristics, treatment and lead times). In addition, some QRs retrieve data on self-reported quality of life (EQ5D, SF-36 and disease-specific measures), lifestyle (smoking) and general health status (World Health Organization performance status, body mass index and blood pressure).Conclusion: Detailed clinical data available in Swedish QRs complement information from government-administered registries and provide an important source not only for assessment and development of quality of care but also for research.

    • Background: Dilated cardiomyopathy (DCM) is a rare disease of largely unknown origin. Previous studies have suggested an increased prevalence of celiac disease (CD) in patients with DCM. These studies, however, were based on a maximum of 5 patients with both CD and DCM. In the present large Swedish population-based cohort study, we examined the risk of idiopathic DCM in patients with CD determined by small-intestinal histopathology.Methods and Results: From 2006 to 2008, we collected duodenal/jejunal biopsy data on CD (equal to villous atrophy, Marsh stage 3, n=29 071 unique individuals) from (all) 28 pathology departments in Sweden. These individuals were compared with 144 429 reference individuals matched for age, sex, calendar year, and county. Data on DCM were obtained through the National Patient Register and confirmed by patient charts and echocardiography data. During follow-up, 17 patients with CD and 52 reference individuals developed idiopathic DCM. Thus, patients with CD were at an increased risk of idiopathic DCM (hazard ratio, 1.73; 95% confidence interval, 1.00 to 3.00), although the risk estimate failed to attain statistical significance (P=0.052).Conclusion: This nationwide study found a moderately but not statistically significantly increased risk of idiopathic DCM in patients with biopsy-verified CD.

  • Risk of Small Bowel Adenocarcinoma, Adenomas, and Carcinoids in a Nationwide Cohort of Individuals With Celiac Disease
  • 2020
  • Ingår i: Gastroenterology. - : American Gastroenterology Association Institute. - 0016-5085 .- 1528-0012. ; 159:5, s. 1686-1694
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND & AIMS: The incidence of small bowel cancers is increasing. Associations have been made between celiac disease (CD) and small bowel cancers, but there have been no detailed studies of large cohorts.METHODS: Through the nationwide Epidemiology Strengthened by Histopathology Reports in Sweden cohort study, we retrieved data from Sweden's 28 pathology departments on all individuals who received a diagnosis of CD from 1965 through 2017. Individuals with CD, defined as duodenal or jejunal villous atrophy (stage 3 Marsh score), were matched with as many as 5 randomly selected reference individuals from the general population. We used stratified Cox regression to calculate hazard ratios (HRs) for small bowel adenocarcinoma, adenomas, and carcinoids.RESULTS: During a median follow-up of 11 years, we identified 48,119 individuals with CD (patients) and 239,249 reference individuals. Beginning at 1 year after a diagnosis of CD, 29 patients (0.06%) received a diagnosis of small bowel adenocarcinoma vs 45 reference individuals (0.02%), 7 patients received a diagnosis of carcinoids vs 31 reference individuals, and 48 patients received a diagnosis of adenomas vs 50 reference individuals. Corresponding HRs were small bowel adenocarcinoma 3.05 (95% confidence interval [CI], 1.86-4.99), carcinoids 0.59 (95% CI, 0.16-2.10), and adenomas 5.73 (95% CI, 3.70-8.88). HRs were independent of sex and age. Overall, there was 1 extra case of small bowel adenocarcinoma in every 2944 patients with CD followed for 10 years. There was an inverse association between mucosal healing risk of future small bowel adenocarcinoma (HR, 0.18; 95% CI, 0.02-1.61), although the HR failed to attain statistical significance.CONCLUSIONS: In an analysis of a nationwide pathology database in Sweden, we found the absolute risk of small bowel adenocarcinoma is low in individuals with CD. However, risks of small bowel adenocarcinoma and adenomas (but not carcinoids) are significantly increased in people with CD compared to people without this disease.

  • The characterisation and risk factors of ischaemic heart disease in patients with coeliac disease
  • 2013
  • Ingår i: Alimentary Pharmacology and Therapeutics. - : Wiley. - 0269-2813 .- 1365-2036. ; 37:9, s. 905-914
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Studies have shown an increased risk of ischaemic heart disease (IHD) in patients with coeliac disease (CD), despite the patients' lack of traditional IHD risk factors.Aim: To characterise IHD according to CD status.Methods: Data on duodenal or jejunal biopsies were collected in 20062008 from all 28 pathology departments in Sweden and were used to define CD (equal to villous atrophy; Marsh stage 3). We used the Swedish cardiac care register SWEDEHEART to identify IHD and to obtain data on clinical status and risk factors at time of first myocardial infarction for this case-only comparison. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). CD patients were compared with general population reference individuals.Results: We identified 1075 CD patients and 4142 reference individuals with subsequent IHD. CD patients with myocardial infarction had lower body mass index (P<0.001) and cholesterol values (P<0.001) and were less likely to be active smokers (OR=0.74; 95% CI=0.560.98) than reference individuals with myocardial infarction. CD patients had less extensive coronary artery disease at angiography (any stenosis: OR=0.80; 95% CI=0.660.97; three-vessel disease: OR=0.73; 95% CI=0.570.94); but there was no difference in the proportions of CD patients with positive biochemical markers of myocardial infarction (CD: 92.2% vs. reference individuals: 91.5%, P=0.766).Conclusion: Despite evidence of an increased risk of IHD and higher cardiovascular mortality, patients with coeliac disease with IHD have a more favourable cardiac risk profile compared with IHD in reference individuals.

  • Guidance for Health Care Leaders During the Recovery Stage of the COVID-19 Pandemic A Consensus Statement
  • 2021
  • Ingår i: JAMA Network Open. - : American Medical Association. - 2574-3805. ; 4:7
  • Tidskriftsartikel (refereegranskat)abstract
    • IMPORTANCE: The COVID-19 pandemic is the greatest global test of health leadership of our generation. There is an urgent need to provide guidance for leaders at all levels during the unprecedented preresolution recovery stage.OBJECTIVE: To create an evidence- and expertise-informed framework of leadership imperatives to serve as a resource to guide health and public health leaders during the postemergency stage of the pandemic.EVIDENCE REVIEW: A literature search in PubMed, MEDLINE, and Embase revealed 10 910 articles published between 2000 and 2021 that included the terms leadership and variations of emergency, crisis, disaster, pandemic, COVID-19, or public health. Using the Standards for Quality Improvement Reporting Excellence reporting guideline for consensus statement development, this assessment adopted a 6-round modified Delphi approach involving 32 expert coauthors from 17 countries who participated in creating and validating a framework outlining essential leadership imperatives.FINDINGS: The 10 imperatives in the framework are; (1) acknowledge staff and celebrate successes; (2) provide support for staff well-being; (3) develop a clear understanding of the current local and global context, along with informed projections; (4) prepare for future emergencies (personnel, resources, protocols, contingency plans, coalitions, and training); (5) reassess priorities explicitly and regularly and provide purpose, meaning, and direction; (6) maximize team, organizational, and system performance and discuss enhancements; (7) manage the backlog of paused services and consider improvements while avoiding burnout and moral distress; (8) sustain learning, innovations, and collaborations, and imagine future possibilities; (9) provide regular communication and engender trust; and (10) in consultation with public health and fellow leaders, provide safety information and recommendations to government, other organizations, staff, and the community to improve equitable and integrated care and emergency preparedness systemwide.CONCLUSIONS AND RELEVANCE: Leaders who most effectively implement these imperatives are ideally positioned to address urgent needs and inequalities in health systems and to cocreate with their organizations a future that best serves stakeholders and communities.

  • Long-term Follow-up of 84 Patients With Giant Prolactinomas-A Swedish Nationwide Study.
  • 2023
  • Ingår i: The Journal of clinical endocrinology and metabolism. - : Oxford University Press. - 1945-7197 .- 0021-972X. ; 108:12
  • Tidskriftsartikel (refereegranskat)abstract
    • To describe the clinical presentation and treatment outcomes in a nationwide cohort of patients with giant prolactinomas.Register-based study of patients with giant prolactinomas [serum prolactin (PRL) > 1000 µg/L, tumor diameter ≥40 mm] identified in the Swedish Pituitary Register 1991-2018.Eighty-four patients [mean age 47 (SD ±16) years, 89% men] were included in the study. At diagnosis, the median PRL was 6305 µg/L (range 1450-253 000), the median tumor diameter was 47 mm (range 40-85), 84% of the patients had hypogonadotropic hypogonadism, and 71% visual field defects. All patients were treated with a dopamine agonist (DA) at some point. Twenty-three (27%) received 1 or more additional therapies, including surgery (n = 19), radiotherapy (n = 6), other medical treatments (n = 4), and chemotherapy (n = 2). Ki-67 was ≥10% in 4/14 tumors. At the last follow-up [median 9 years (interquartile range (IQR) 4-15)], the median PRL was 12 µg/L (IQR 4-126), and the median tumor diameter was 22 mm (IQR 3-40). Normalized PRL was achieved in 55%, significant tumor reduction in 69%, and combined response (normalized PRL and significant tumor reduction) in 43%. In the primary DA-treated patients (n = 79), the reduction in PRL or tumor size after the first year predicted the combined response at the last follow-up (P < .001 and P = .012, respectively).DAs effectively reduced PRL and tumor size, but approximately 1 patient out of 4 needed multimodal treatment. Our results suggest that the response to DA after 1 year is useful for identifying patients who need more careful monitoring and, in some cases, additional treatment.

  • Emergency hospital admissions, prognosis, and population mortality in Norway during the first wave of the Covid-19 epidemic
  • 2022
  • Ingår i: Scandinavian Journal of Public Health. - : Sage Publications. - 1403-4948 .- 1651-1905. ; 50:6, s. 795-802
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: During the first wave of the Covid-19 epidemic, a national lockdown was established in Norway, and inhabitants were asked to contact healthcare only if absolutely necessary. We investigated hospital admissions and mortality due to non-Covid-19 disease during the lockdown compared to previous years.METHODS: We compared the number of emergency admissions and in-hospital fatality for diagnoses probably unaffected (acute myocardial infarction, acute abdominal conditions, cerebrovascular diseases) and affected by the lockdown (infections, injuries) in the South-Eastern Health Region of Norway during weeks 12-22, 2020, compared to the mean of the same period in the years 2017-2019. We also compared population mortality March-May 2020, to the mean of the same period in years 2017-2019.RESULTS: A total of 280,043 emergency admissions were observed; 20,911 admissions probably unaffected, and 30,905 admissions probably affected by the lockdown. Admissions due to diagnoses probably unaffected was reduced by 12% (95% confidence interval (CI) 9-15%), compared to 2017-2019. Admissions for diagnoses probably affected was reduced by 30% (95% CI 28-32%). There was a 34% reduction in in-hospital fatality due to acute myocardial infarction (95% CI 4-56%), 19% due to infections (95% CI 1-33%), and no change for the other diagnoses, compared to 2017-2019. The risk of in-hospital mortality to total mortality was lower for acute myocardial infarction (relative risk 0.85, 95% CI 0.73-0.99) and injuries (relative risk 0.83, 95% CI 0.70-0.98).CONCLUSIONS: Even though fewer patients were admitted to hospital, there was no increase in in-hospital fatality or population mortality, indicating that those who were most in need still received adequate care.

  • Förslag på utformning av ett livscykelbaserat system för kartläggning av flöden av omställningskritiska råmaterial  i den svenska teknosfären
  • 2023
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Den 24 mars 2021 gav regeringen SGU i uppdrag att tillsammans med Naturvårdsverket arbeta för att öka möjligheterna till hållbar utvinning av mineral och metaller från sekundära råmaterial (Näringsdepartementet, 2021). Uppdraget innehåller ett antal strecksatser varav den fjärde handlar om att ge en överblick över flöden av kritiska mineral och metaller samt att föreslå system för hur livscykelanalys och spårbarhet kan utformas för att bidra till en cirkulär ekonomi. Denna rapport avhandlar en del av strecksatsen och beskriver resultatet av arbetet med att föreslå det efterfrågade systemet.Inom ramen för arbetet har det varit nödvändigt att tolka och delvis omdefiniera några av de efterfrågade delarna i systemet. I den här studien läggs tyngdpunkten på totala mängder, fördelning och användning av råmaterial, snarare än genom vilka värdekedjor ett visst delflöde av råmaterial har flödat eller vilket hållbarhetsavtryck det råmaterialflödet har orsakat. För att tydliggöra den avgränsningen benämns det system som föreslås i den här studien för ett kartläggningssystem i stället för ett spårbarhetssystem. Ett system för att spåra eller kartlägga kritiska råmaterial med syftet att bidra till en cirkulär ekonomi bör initialt inte inriktas på att samla in livscykeldata eller på att ta fram nya LCA-undersökningar, utan i stället fokusera på var olika material finns, i vilka mängder dessa förekommer samt var i livscykeln (teknosfären) dessa befinner sig och när dessa (om möjligt) kan bli tillgängliga för att återanvändas eller återvinnas. I ett uppbyggnadsskede är det därmed ett livscykelperspektiv som behövs i systemet och inte ett system för livscykelanalys.I arbetet med att ta fram och föreslå ett system har det ingått att beskriva befintliga datakällor, hur ett beräkningssystem skulle kunna utformas samt att beskriva hur datakällor och beräkningar ska kunna kombineras till ett system som också tar hänsyn till det arbete som inletts med digitala produktpass som ett led i den nya ekodesignförordningen som föreslås implementeras inom EU framöver.SMED förordar att ett framtida livscykelbaserat kartläggningssystem för kritiska råmaterial i den svenska teknosfären utvecklas med en så kallad bottom-up-ansats. Det innebär ett mer komplext system som ställer större krav på datainsamlingen än med en top-down-ansats. Samtidigt lägger det grunden för ett system som kan bli varaktigt över tid och som fullt ut kan dra fördel av den dramatiska ökningen av tillgängliga produktdata som de digitala produktpassen troligtvis kommer att innebära. Utformningen av och innehållet i produktpassen kommer regleras i den delegerade akten för respektive produktgrupp. Begränsad tillgång till produktdata har hittills varit det främsta argumentet för en top-down-ansats. Den pågående och samhällsgenomgripande omställningen av det svenska och europeiska energisystemet kommer att innebära ett växande materialberoende. SMED anser därför att kartläggningssystemet med stor sannolikhet kommer att vara relevant under lång tid framöver, vilket väl motiverar en hög inledande ambitionsnivå för att från början utveckla ett system att växa i. Systemet blir av nödvändighet mycket dataintensivt, men bygger i hög grad på data som samlas in centralt.Som framgår i flera avsnitt i den här rapporten har kartläggningssystemet utformats för att vara förenligt med de initiativ som SMED bedömer vara de viktigaste initiativen. Särskild uppmärksamhet ges åt batteriförordningen och ekodesignförordningens produktpass på EU-nivå och Avfallsregistret på nationell nivå.En framgångsfaktor för det föreslagna kartläggningssystemet blir att fortlöpande bevaka utvecklingen på området för att både säkerställa att Sveriges nationella system blir konsistent med de framväxande systemen på EU-nivå, och att identifiera och utnyttja de möjligheter till synergier mellan olika system och olika aktörer som kartläggningssystemet kommer att medföra. Inte minst har det potentialen att lindra uppgiftslämnarbördan för näringslivet, eftersom delar av den data som kartläggningssystemet behöver samtidigt efterfrågas och i många fall begärs för andra ändamål.Sammantaget kommer SMED till slutsatsen att mycket talar för att gå vidare med en utveckling av ett kartläggningssystem enligt vad som rekommenderas vidare i rapporten. För det fall de digitala produktpassen implementeras i en nära framtid och kan tillhandahålla den data som idag förespeglas kommer utvecklingskostnader och uppgiftslämnarbördor att hållas nere väsentligt. Å andra sidan, om data över flöden av kritiska råmaterial av ett eller annat skäl inte kommer att tillhandahållas av produktpassen ökar värdet av ett svenskt kartläggningssystem ytterligare, eftersom det då (så vitt vi kan förutse idag) inte kommer att finnas något annat system som kan teckna den nödvändiga kartan.

  • The contribution of population age-sex structure to the excess mortality estimates of 2020–2021 in Denmark, Finland, Iceland, Norway, and Sweden
  • 2023
  • Ingår i: SSM - Population Health. - : Elsevier BV. - 2352-8273. ; 22
  • Tidskriftsartikel (refereegranskat)abstract
    • The Nordic countries offer an ideal case study of the COVID-19 pandemic due to their comparability, high data quality, and variable mitigations. We investigated the age- and sex-specific mortality patterns during 2020–2021 for the five Nordic countries and analysed the total age- and sex-adjusted excess deaths, ratios of actual to expected death rates, and age-standardized excess death estimates. We assessed excess deaths using several time periods and sensitivity tests, and 42 sex and age groups. Declining pre-pandemic age-specific death rates reflected improving health demographics. These affect the expected death estimates and should be accounted for in excess mortality models. Denmark had the highest death rates both before and during the pandemic, whereas in 2020 Sweden had the largest mortality increase. The age-standardized mortality of Denmark, Iceland and Norway was lowest in 2020. 2021 was one of the lowest mortality years for all Nordic countries. The total excess deaths in 2020–2021 were dominated by 70−89-year-olds, were not identified in children, and were more pronounced among men than women. Sweden had more excess deaths in 2020 than in 2021, whereas Finland, Norway and Denmark had the opposite. Our study provides new details on Nordic sex- and age-specific mortality during the first two years of the pandemic and shows that several metrics are important to enable a full understanding and comparison of the pandemic mortality.

  • Birth weight, sex, and celiac disease : a nationwide twin study
  • 2017
  • Ingår i: Clinical Epidemiology. - : DOVE Medical Press Ltd.. - 1179-1349. ; 9, s. 567-577
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Earlier research suggests that birth weight may be associated with celiac disease (CD), but the direction of association has been unclear potentially due to confounding effect from genetic and intrafamilial factors. Through within-twin analyses, we aimed to minimize confounding effects such as twins that share genetic and early environmental exposures.Materials and methods: Using the Swedish Twin Registry, we examined the birth weight of 146,830 twins according to the CD status. CD was defined as having villous atrophy according to a small intestinal biopsy reports.Results: The prevalence of diagnosed CD was 0.5% (n=669), and we included 407 discordant pairs of CD-non-CD twins. Comparing the 669 CD patients with non-CD twins, the association between birth weight and future CD was not statistically significant (odds ratio [OR] per 1000 g increase in birth weight: 1.16; 95% confidence interval [CI]=0.97-1.38). In males, the association was positive and statistically significant (OR=1.50; 95% CI=1.11-2.02). However, the association was not significant in within-pair analyses for both dizygotic and monozygotic twins and for both sexes.Conclusion: This population-based study found that in male twins, higher birth weight was associated with higher risk of CD. However, when comparing discordant twin pairs in within-twin pair analyses, there was no statistically significant association between birth weight, intrauterine growth, and future risk of CD.

  • Ingår i: Clinical Gastroenterology and Hepatology. - : Elsevier. - 1542-3565 .- 1542-7714. ; 20:2, s. e111-e131
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Celiac disease (CD) is associated with increased mortality, in part due to cancer. Most studies investigating this cancer risk involved patients diagnosed before widespread increases in CD diagnosis rates and access to gluten-free food. We performed a population-based study of the risk of cancer in CD.METHODS: We identified all patients in Sweden with CD as defined as duodenal villus atrophy, using the ESPRESSO cohort. Each patient was matched to ≤5 controls by age, sex, and county. We used stratified Cox proportional-hazards model, following patients from diagnosis until first cancer, or by December 31, 2016.RESULTS: Among 47,241 patients with CD, 30,080 (64%) were diagnosed since 2000. After a median follow-up of 11.5 years, the incidence of cancer was 6.5 and 5.7 per 1000 person-years in CD patients and controls, respectively. The overall risk of cancer was increased (hazard ratio[HR] 1.11; 95%CI 1.07-1.15), but was only significantly elevated in the first year after CD diagnosis (HR 2.47; 95%CI 2.22-2.74), and not subsequently (HR 1.01; 95%CI 0.97-1.05), though the risks of hematologic, lymphoproliferative, hepatobiliary, and pancreas cancers persisted. The overall risk was highest in those diagnosed with CD after age 60 years (HR 1.22; 95%CI 1.16-1.29) and was not increased in those diagnosed before age 40. The cancer risk was similar among those diagnosed with CD before or after the year 2000.CONCLUSIONS: There is an increased risk of cancer in CD, even in recent years, but this risk increase is confined to those diagnosed with CD after age 40, and is primarily present within the first year of diagnosis.

  • Mucosal healing and the risk of ischemic heart disease or atrial fibrillation in patients with celiac disease : a population-based study
  • 2015
  • Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 10:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Patients with celiac disease (CD), characterized histologically by villous atrophy (VA) of the small intestine, have an increased risk of ischemic heart disease (IHD) and atrial fibrillation (AF), risks that persist for years after commencing the gluten-free diet. It is unknown whether persistent VA on follow-up biopsy, rather than mucosal healing, affects the risk of IHD or AF.Methods: We identified patients with histologic evidence of CD diagnosed at all 28 pathology departments in Sweden. Among patients who underwent a follow-up small intestinal biopsy, we compared patients with persistent VA to those who showed histologic improvement, with regard to the development of IHD (angina pectoris or myocardial infarction) or AF.Results: Among patients with CD and a follow-up biopsy (n = 7,440), the median age at follow-up biopsy was 25 years, with 1,063 (14%) patients who were >= 60 years at the time of follow-up biopsy. Some 196 patients developed IHD and 205 patients developed AF. After adjusting for age, gender, duration of CD, calendar period, and educational attainment, there was no significant effect of persistent VA on IHD (adjusted HR 0.97; 95%CI 0.73-1.30). Adjusting for diabetes had a negligible effect (adjusted HR 0.98; 95%CI 0.73-1.31). There was no significant association between persistent VA and the risk of AF (adjusted HR 0.98; 95%CI 0.74-1.30).Conclusions: In this population-based study of patients with CD, persistent VA on follow-up biopsy was not associated with an increased risk of IHD or AF. Failed mucosal healing does not influence the risk of these cardiac events.

    • BACKGROUND & AIMS: Few studies have explored the link between childhood celiac disease and long-term psychiatric comorbidities. We performed a population-based cohort study of associations between childhood celiac disease and psychiatric disorders and investigated whether risk persists into adulthood.METHODS: We performed a nationwide study in Sweden using data from the ESPRESSO cohort. In this cohort, 19,186 children with a diagnosis of biopsy-verified celiac disease from 1973 through 2016 were identified from Sweden's 28 pathology departments. Each patient was matched with as many as 5 reference children (controls, n=94,249). Data on psychiatric disorders were obtained from the patient register. We used Cox proportional modeling to estimate hazard ratios (HRs).RESULTS: During a median follow-up time of 12.3 years, 3174 children (16.5%) with celiac disease received a new diagnosis of a psychiatric disorder, compared with 13,286 controls (14.1%). Corresponding incidence rates were 12.2 per 1000 person-years (95% Cl, 11.8-12.7) vs 10.3 per 1000 person-years (95% Cl, 10.2-10.5). Childhood celiac disease was associated with a 19% increase in risk of any psychiatric disorder (95% Cl, 1.14-1.23); the increase in risk was observed in all childhood age groups. The highest HRs were seen in the first year after celiac diagnosis (HR, 1.70; 95% Cl, 1.41-2.05). The risk increase persisted into adulthood (older than 18 years: HR, 1.11; 95% Cl, 1.04-1.17). We found increased risks of mood disorders (HR, 1.20; 95% CI, 1.12-1.28), anxiety disorders (HR, 1.12; 95% CI, 1.06-1.19), eating disorders (HR, 1.34; 95% CI, 1.18-1.51), attention deficit hyperactivity disorder (HR, 1.29; 95% CI, 1.20-1.39), and autism spectrum disorder (HR, 1.47; 95% CI, 1.32-1.64). We found no statistically significant risk increase for psychotic disorders, psychoactive substance misuse, behavioral disorders, personality disorders, suicide attempt, or suicide. Celiac disease was also linked to an increased use of psychiatric drugs (HR, 1.34; 95% CI, 1.24-1.43). A conditional logistic regression found that psychiatric disorders were also more common prior to diagnosis of celiac disease (odds ratio, 1.56; 95% Cl, 1.39-1.76).CONCLUSIONS: Childhood celiac disease is associated with increased risk of subsequent psychiatric disorders, which persists into adulthood. Mental health surveillance should be integral in the care of celiac disease.

  • Ingår i: Alimentary Pharmacology and Therapeutics. - : John Wiley & Sons. - 0269-2813 .- 1365-2036. ; 48:10, s. 1091-1098
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Coeliac disease has been linked to anxiety and depression. However, their association with mucosal healing is unknown.Aim: To examine the relationship between anxiety, depression and mucosal healing in coeliac disease.Methods: Between 1969 and 2008, we collected data on all small intestinal biopsies with villous atrophy from Sweden's 28 pathology departments. We restricted our cohort to individuals with data on follow-up biopsy (either persistent villous atrophy [n = 3317] or mucosal healing [n = 4331]). Through Cox regression, we estimated hazard ratios (HRs) for anxiety or depression.Results: Conclusion APPENDIX During follow-up, 123 (2.8/1000 person-years) individuals with mucosal healing had developed anxiety, compared to 94 (2.1/1000 person-years) with persistent villous atrophy. Mucosal healing was hence associated with a higher risk of future anxiety (HR = 1.49; 95% CI = 1.12-1.96). Similarly, 167 (3.8/1000 person-years) individuals with mucosal healing developed depression, compared to 148 (3.3/1000 person-years) with persistent villous atrophy, corresponding to a HR of 1.25 (95% CI = 0.99-1.59). Mucosal healing was more common in individuals with prior diagnoses of anxiety or depression before follow-up biopsy. Anxiety diagnosed between diagnostic and follow-up biopsy for coeliac disease was associated with an almost nine-fold increased chance of mucosal healing (odds ratio = 8.94; 95%CI = 2.03-39.27).Conclusion: Anxiety and depression are more common in coeliac disease patients with mucosal healing, both before and after follow-up biopsy, an association potentially mediated through more vigilant compliance with a gluten-free diet. This finding raises concern that achieving the goal of mucosal healing may come at a cost of an increased risk of mood disorders.

    • BACKGROUND & AIMS: Partner burden is common in celiac disease (CD), but it is unclear if parents of children with CD have increased burden, and if this may translate into depression and anxiety meriting healthcare.METHODS: Nationwide population-based study of 41,753 parents and spouses ("caregivers") to 29,096 celiac patients and 215,752 caregivers to 144,522 matched controls. Caregivers were identified from the Swedish Total Population Register, and linked to data on psychiatric disease in the National Patient Registry. Hazard ratios (HRs) for depression, anxiety, and (as a reference outcome measure) bipolar disorder were examined in a lifetime fashion but also in temporal relationship to date of CD diagnosis using Cox regression. A priori, we focused on parents of individuals diagnosed ≤19 years of age (children at the age of disease onset) and spouses of individuals diagnosed in adulthood, as such parents and spouses ("high-risk caregivers") were most likely to live together with the patient at time of disease onset.RESULTS: On Cox analysis, depression was 11% more common in high-risk caregivers (HR=1.11: 95%CI=1.03-1.19) than in control caregivers while anxiety was 7% more common (HR=1.07: 95%CI=0.98-1.16). Combining anxiety and depression into a composite outcome measure, there was an 8% statistically significant risk increase (95%CI=1.02-1.14). The highest excess risks for both depression and anxiety were seen just before and 4-8 years after the CD diagnosis. In contrast, bipolar disorder was not more common in caregivers to CD patients.CONCLUSION: Caregivers to patients with CD may be at increased risk of severe burden.

    • Background and Aims: A recent study found a 10-fold increased risk of celiac disease (CD) in individuals with Henoch-Schonlein purpura (HSP), but the confidence interval (CI) was wide.Methods: The retrospective cohort study of all patients with CD in Sweden, diagnosed through small intestinal biopsy from 1969 to 2008 (n = 29,077). Each individual with CD was matched to up to 5 controls (n = 144,433). Data on study participants were linked to diagnostic codes for HSP in the National Patient Registry. Through Cox regression we estimated hazard ratios for CD and later HSP. Through logistic regression we calculated odds ratios for HSP preceding CD.Results: During follow-up 19 individuals with CD and 99 controls developed HSP. This corresponded to a hazard ratio of 0.96 (95% CI, 0.59-1.56). Looking backward, we found no increased risk of earlier HSP in patients with CD (odds ratio = 1.02; 95% CI, 0.601.72).Conclusions: In this study of more than 29,000 patients with CD, we found no increased risk of HSP before or after CD.

    • Background and aims: Clinical experience suggests that patients with coeliac disease (CD) are more prone to develop herpes zoster (HZ), but robust studies are lacking.Methods: We identified 29,064 patients with CD 1969-2008 using biopsy report data from Sweden's 28 pathology departments. CD was equalled to villous atrophy (Marsh histopathology grade III). Each patient was matched on age, sex, calendar year and county of residence to up to five reference individuals (n=144,342) from the general population. We then used Cox regression to estimate hazard ratios (HRs) for future HZ (defined as having a hospital-based inpatient or outpatient record of this diagnosis in the Swedish Patient Register).Results: During follow-up, 154 (0.53%) individuals with CD and 499 (0.35%) reference individuals developed HZ. Among individuals aged >= 60 years, 1.06% of CD individuals and 0.85% of reference individuals had a lifetime record of HZ. Overall, CD was associated with a 1.62-fold increased risk of HZ (95% CI=1.35-1.95), and was seen also when we considered comorbidity with lymphoproliferative disease, systemic lupus erythematosus, type 1 diabetes, thyroid disease, rheumatoid disease and excluded individuals with a record of dermatitis herpetiformis. The increased risk remained significant after more than five years of follow-up (1.46; 1.16-1.84)Conclusions: CD is associated with HZ, the increased relative risk persists over time from celiac diagnosis but the absolute risk is small.

  • Appendectomy and future risk of microscopic colitis : a population-based case-control study in Sweden
  • 2023
  • Ingår i: Clinical Gastroenterology and Hepatology. - : Elsevier. - 1542-3565 .- 1542-7714. ; 21:2, s. 467-475.e2
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND AND AIMS: Microscopic colitis (MC) is an inflammatory bowel disease and a common cause of chronic diarrhea. Appendectomy has been suggested to have immunomodulating effects in the colon, influencing the risk of gastrointestinal disease. The relationship between appendectomy and MC has only been sparsely studied.METHODS: This was a case-control study based on the nationwide ESPRESSO cohort, consisting of histopathological examinations in Sweden, linked to national registers. Patients with MC were matched to population controls by age, sex, calendar year of biopsy and county of residence. Data on antecedent appendectomy and comorbidities were retrieved from the Patient Register. Unconditional logistic regression models were conducted presenting odds ratios (ORs) and 95% confidence intervals (Cl) adjusted for country of birth and matching factors. Further sub-analyses were made based on MC subtypes (lymphocytic colitis [LC] and collagenous colitis [CC]), follow-up time post appendectomy and severity of appendicitis.RESULTS: The study included 14,520 cases of MC and 69,491 controls, among these 7.6% (n=1,103) and 5.1% (n=3,510), respectively, had a previous appendectomy ≥1 year prior to MC/matching date. Patients with a previous appendectomy had an increased risk of MC in total (OR 1.50, 95% CI 1.40-1.61); and per subtype CC (OR 1.67, 95% CI 1.48-1.88), LC (OR 1.42, 95% CI 1.30-1.55). The risk remained elevated throughout follow-up, and the highest risk was observed in non-complicated appendicitis.CONCLUSIONS: This nationwide case-control study found a modestly increased risk of developing MC following appendectomy.

  • High experienced continuity in breast cancer care is associated with high health related quality of life
  • 2018
  • Ingår i: BMC Health Services Research. - : BIOMED CENTRAL LTD. - 1472-6963. ; 18
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: High experienced continuity is known to be associated with lower needs for supportive care and most likely higher quality of life. On this background, the aim of this study was to investigate if patient-experienced continuity of care was associated with health-related quality of life (HRQoL) in breast cancer patients treated at two different-sized breast cancer units.Methods: In 2016, two questionnaires, "Statements on experienced continuity of care" and "The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)", were sent out to patients diagnosed between 2011 and 2014 at two different-sized breast cancer units in Sweden. Lead times and other data reflecting medical quality were collected from the patients' medical records and from the National Swedish Breast Cancer Quality Register.Results: Of 356 eligible patients, 231 (65%) answered the questionnaires, of whom 218 patients were included in the analyses. A statistically significant association was found between high experienced continuity and high global HRQoL (p = 0.03). Continuity was higher at the smaller unit, while no major differences between the units were found regarding medical quality or lead times.Conclusion: The study found that high experienced continuity and HRQoL was strongly associated. A statistically significant higher continuity of care was found at the smaller unit, in line with what was expected. The absence of clinically relevant differences in lead times and medical quality may indicate that continuity could be achieved without loss of quality.

    • Statins effectively lower LDL cholesterol levels in large studies and the observed interindividual response variability may be partially explained by genetic variation. Here we perform a pharmacogenetic meta-analysis of genome-wide association studies (GWAS) in studies addressing the LDL cholesterol response to statins, including up to 18,596 statin-treated subjects. We validate the most promising signals in a further 22,318 statin recipients and identify two loci, SORT1/CELSR2/PSRC1 and SLCO1B1, not previously identified in GWAS. Moreover, we confirm the previously described associations with APOE and LPA. Our findings advance the understanding of the pharmacogenetic architecture of statin response.

    • BACKGROUND: IgA nephropathy (IgAN) is the most common primary glomerulonephritis affecting all ages and both sexes, but there is a lack of studies on its association with cancer and whether it is a paramalignant condition.METHODS: In a Swedish population-based cohort study we compared the risk of cancer among 3,882 biopsy-verified IgAN patients diagnosed during 1974-2011 with 19,341 reference individuals and followed them until 2015. Cox regression was used to estimate hazard ratios (HRs) for cancer in IgAN patients versus controls, and conditional logistic regression assessed the risk of cancer before the IgAN was confirmed.RESULTS: During a median follow-up of 12.6 years, 488 (12.6%) patients with IgAN and 1,783 (9.2%) matched reference individuals were diagnosed with cancer (HR 1.70; 95% confidence interval, 95%CI, 1.52-1.89). The increased risk was only seen in IgAN patients developing end stage renal disease (ESRD), with an HR of 4.01 (95%CI 3.33-4.82) for any cancer and HR of 2.22 (95%CI 1.79-2.75) when excluding non-melanoma skin cancer (NMSC). Non-ESRD IgAN patients did not have an increased overall cancer risk (HR 1.13; 95%CI 0.99-1.30). There was no increased risk of cancer preceding IgAN diagnosis (odds ratio 1.10; 95%CI 0.92-1.32).CONCLUSION: We found no support for IgAN being a paramalignant condition. There was an increased risk of cancer in IgAN patients, but only for those with ESRD. Our results indicate approximately 6 extra cancer case per 100 IgAN patients with ESRD per 10 years, or >17 extra cases if including NMSC as well.

  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Case reports suggest an association between inflammatory bowel disease, a chronic autoimmune condition linked to increased circulating IgA levels, and IgA nephropathy, the most common form of primary GN and a leading cause of ESKD.METHODS: In a Swedish population-based cohort study, we compared 3963 biopsy-verified IgA nephropathy patients with 19,978 matched controls between 1974 and 2011, following up participants until 2015. Inflammatory bowel disease data and ESKD status were obtained through national medical registers. We applied Cox regression to estimate hazard ratios (HRs) for future inflammatory bowel disease in IgA nephropathy and conditional logistic regression to assess risk of earlier inflammatory bowel disease in IgA nephropathy. We also explored whether inflammatory bowel disease affects development of ESKD in IgA nephropathy.RESULTS: During a median follow-up of 12.6 years, 196 (4.95%) patients with IgA nephropathy and 330 (1.65%) matched controls developed inflammatory bowel disease (adjusted HR, 3.29; 95% confidence interval [95% CI], 2.73 to 3.96). Inflammatory bowel disease also was more common before a confirmed IgA nephropathy diagnosis. Some 103 (2.53%) IgA nephropathy patients had an earlier inflammatory bowel disease diagnosis compared with 220 (1.09%) controls (odds ratio [OR], 2.37; 95% CI, 1.87 to 3.01). Both logistic regression (OR, 2.60; 95% CI, 2.02 to 3.35) and time-varying Cox regression (HR, 1.84; 95% CI, 1.33 to 2.55) demonstrated that inflammatory bowel disease was associated with increased ESKD risk in patients with IgA nephropathy.CONCLUSIONS: Patients with IgA nephropathy have an increased risk of inflammatory bowel disease both before and after their nephropathy diagnosis. In addition, among patients with IgA nephropathy, comorbid inflammatory bowel disease elevates the risk of progression to ESKD.

  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: The Swedish Renal Registry (SRR) is a unique national quality registry that monitors the clinical trajectory of patients with chronic kidney disease (CKD). We have validated the biopsy data registered in the SRR for IgA Nephropathy (IgAN) diagnosis.METHODS: In total 25% of all patients (n = 142), registered with IgAN in the SRR after having performed a kidney biopsy during 2015-2019, were randomly selected. We obtained original biopsy and medical records for 139 (98%) patients. We evaluated the IgAN diagnosis using a standardized template, calculated its positive predictive value (PPV) with 95% confidence interval (CI) and reported clinical features at the time of diagnosis.RESULTS: A histological and clinical diagnosis of IgAN was confirmed in 132 of the 139 patients, yielding a PPV of 95% (95% CI 90-98%). Median age was 46 years (range: 18-85) and the male:female ratio was 2.1:1. The median creatinine level was 123 µmol/L, with a corresponding estimated glomerular filtration rate (eGFR) level of 51 mL/min/1.73m2. Histological features of IgA deposits were seen in all patients, hypercellularity in 102/132 (77.2%), C3 deposits in 98/132 (72.4%) and C1q deposits in 27/132 (20.5%) of the cases.CONCLUSION: Validating data is not research per se, but continuous validation of medical registries is an important feature necessary to ensure reliable data and the foundation of good epidemiological data for future research. Our validation showed a high PPV (95%) for IgAN diagnosis registered in the SRR. Clinical characteristics were consistent with previous reports. The biopsy data in the SRR will be a valuable resource in future IgAN research.

  • Ingår i: JAC - Antimicrobial Resistance. - : Oxford University Press. - 2632-1823. ; 5:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: To analyse the prevalence of respiratory tract infection (RTI) episodes with and without antibiotic prescriptions in adult patients in Norwegian general practice during the period 2012-2019.Methods: Observational study linking data from the Norwegian Control and Payment for Health Reimbursements Database and the Norwegian Prescription Database. Episodes of acute RTIs in patients aged 18 years or older were identified and linked to antibiotic prescriptions dispensed within 7 days after diagnosis. We analysed annual infection rates and antibiotic prescription rates and antibiotics prescribed for the different RTI conditions.Results: RTI episode rate per 1000 inhabitants was 312 in 2012 and 277 in 2019, but showed no linear trend of change during the study period (P = 0.205). Antibiotic prescription rate decreased from 37% of RTI episodes in 2012 to 23% in 2019 (P < 0.001). The reduction in prescribing was most pronounced for episodes coded with ICPC-2 symptom diagnoses, as well as upper RTIs, influenza, acute bronchitis and sinusitis. Prescriptions for phenoxymethylpenicillin decreased from 178 746 in 2012 to 143 095 in 2019, but increased as proportion of total antibiotic prescriptions from 40% in 2012 to 53% in 2019 (P < 0.001).Conclusions: This study demonstrates stable RTI episode rates and reduced antibiotic prescription rates for RTIs for adults in Norwegian general practice 2012-2019. We also observed a shift towards relatively more use of phenoxymethylpenicillin and less broad-spectrum antibiotics. These changes are in line with the aims of the Norwegian strategy against antibiotic resistance.

    • Objectives: To investigate complication rates of acute sinusitis in general practice, and whether antibiotic prescribing had an impact on complication rate.Methods: All adult patients diagnosed with sinusitis in Norwegian general practice between 1 July 2012 and 30 June 2019 were included. GP consultation data from the Norwegian Control and Payment for Health Reimbursements Database were linked with antibiotic prescriptions (Norwegian Prescription Database) and hospital admissions (Norwegian Patient Registry). Main outcomes were sinusitis-related hospitalizations and severe complications within 30 days. Logistic regression was used to estimate associations between antibiotic prescriptions, prespecified risk factors, individual GP prescribing quintile, and outcomes.Results: A total of 711 069 episodes of acute sinusitis in 415 781 patients were identified. During the study period, both annual episode rate (from 30.2 to 21.2 per 1000 inhabitants) and antibiotic prescription rate (63.3% to 46.5%; P < 0.001) decreased. Yearly hospitalization rate was stable at 10.0 cases per 10 000 sinusitis episodes and the corresponding rate of severe complications was 3.2, with no yearly change (P = 0.765). Antibiotic prescribing was associated with increased risk of hospitalization [adjusted OR 1.8 (95% CI 1.5-2.1)] but not with severe complications. Individual GP prescribing quintile was not associated with any of the outcomes, whereas risk factors such as previous drug abuse, or head injury, skull surgery or malformations, and being immunocompromised were significantly associated with increased risk of both outcomes.Conclusions: Severe complications of acute sinusitis were rare and no protective effect of high prescribing practice among GPs was found. Recommendations to further reduce antibiotic prescribing are generally encouraged, except for high-risk groups.

    • BACKGROUND & AIMS: Use of antibiotics affects the composition of the microbiome and might affect development of colorectal polyps, which are precursors to colorectal cancer.METHODS: We performed a nested case-control study in Sweden of 45,744 patients with a colorectal polyp (cases) in the nationwide gastrointestinal ESPRESSO histopathology cohort, using unaffected full siblings as controls (n = 93,307). Polyps were classified by morphology SnoMed codes into conventional adenomas and serrated polyps. Through linkage to the Prescribed Drug Register, we assessed use and cumulative dispensations of antibiotic until 1 year prior to polyp diagnosis for cases and their sibling controls.RESULTS: During a median study period of 6.9 years, compared with non-users, users of antibiotics (including 28,884 cases [63.1%] and 53,222 sibling controls [57.0%]) had a higher risk of colorectal polyps (odds ratio [OR], 1.08; 95% CI, 1.04-1.13). Risk increased with higher number of dispensations (OR for >= 6 dispensations, 1.33; 95% CI, 1.25-1.43) (P-trend <.0001). We observed a stronger association with polyps for broad-spectrumantibiotics (OR comparing users to non-users, 1.23; 95% CI, 1.18-1.29) than for narrow-spectrum antibiotics (OR, 1.05; 95% CI, 1.01-1.10), and for tetracyclines and quinolones (OR, 1.21) than penicillin and other classes (ORs ranged from 1.04 to 1.16). The findings remained robust with several sensitivity analyses, including use of a 2-year lead-in period for antibiotic assessment and correction for misclassification in controls. Use of broad-spectrum antibiotics was more strongly associated with risk of serrated polyps (OR, 1.29; 95% CI, 1.21-1.38) compared with risk of conventional adenomas (OR, 1.17; 95% CI, 1.11-1.24). We found no differences in risk of colon vs rectal polyps with antibiotic use (P-heterogeneity >.10). We found stronger associations for younger (<50 years) vs older adults (>= 50 years) for users of quinolones, sulfonamides, trimethoprim, and cephalosporins (P-interaction <.001).CONCLUSIONS: In a nationwide case-control study in Sweden, after accounting for hereditary and early life environmental factors, antibiotic use was associated with increased risk of colorectal polyps. Our findings indicate a role for intestinal dysbiosis in early stages of colorectal carcinogenesis.

    • INTRODUCTION: Endoscopic screening reduces colorectal cancer (CRC) incidence and mortality. Individuals with a negative result are recommended to undergo rescreening within a 10-year interval, but evidence supporting this advice is limited.METHODS: We performed a matched cohort study using prospectively collected data from 88,798 individuals in Sweden with normal mucosa at the first colorectal biopsy (aged ≥50 years) in the nationwide gastrointestinal epidemiology strengthened by histopathology reports (ESPRESSO) (1965-2016) and 424,150 matched reference individuals from the general population. Cox proportional hazards regression estimated multivariable hazard ratios and 95% confidence intervals (CIs) of CRC incidence and mortality of incident CRCs up to 44 years of follow-up.RESULTS: In the normal biopsy and reference groups, respectively, the 20-year incidences of CRC were 3.03% and 4.53% and the 20-year mortalities of incident CRC were 0.89% and 1.54%. The multivariable hazard ratio comparing the normal biopsy and reference groups was 0.62 for CRC incidence (95% CI = 0.58-0.66, P < 0.001) and 0.56 for mortality of incident CRC (95% CI = 0.49-0.64, P < 0.001). When assessed by time interval after biopsy, lower CRC incidence and mortality were observed throughout the follow-up. The association seemed weaker for proximal colon cancer than for rectal and distal colon cancer.DISCUSSION: A normal colorectal biopsy was associated with lower CRC incidence and mortality for at least 20 years after the examination. Our findings confirm previous data and suggest that the screening intervals after a normal colonoscopy could be longer than the commonly recommended 10 years. It may be time to open the discussion for a revision of the international guidelines.

  • Risk of colorectal cancer in first degree relatives of patients with colorectal polyps : nationwide case-control study in Sweden

    • OBJECTIVE: To assess the risk of colorectal cancer (CRC) in first degree relatives (parents and full siblings) of patients with precursor lesions (polyps) for CRC.DESIGN: Case-control study.SETTING: Linkage to the multi-generation register and gastrointestinal ESPRESSO (Epidemiology Strengthened by histoPathology Reports in Sweden) histopathology cohort in Sweden.PARTICIPANTS: 68 060 patients with CRC and 333 753 matched controls.MAIN OUTCOME MEASURES: Multivariable adjusted odds ratios of CRC according to the number of first degree relatives with a colorectal polyp and the histology of polyps and age at diagnosis in first degree relatives. Subgroup analysis was also performed according to age at CRC diagnosis and evaluated the joint association of family history of colorectal polyps and family history of CRC.RESULTS: After adjusting for family history of CRC and other covariates, having a first degree relative with a colorectal polyp (8.4% (5742/68 060) in cases and 5.7% (18 860/333 753) in controls) was associated with a higher risk of CRC (odds ratio 1.40, 95% confidence interval 1.35 to 1.45). The odds ratios ranged from 1.23 for those with hyperplastic polyps to 1.44 for those with tubulovillous adenomas. To better put this risk in perspective, the age specific absolute risk of colon and rectal cancers was estimated according to family history of polyps based on the 2018 national CRC incidence in Sweden. For example, the absolute risk of colon cancer in individuals aged 60-64 years with and without a family history of colorectal polyp was, respectively, 94.3 and 67.9 per 100 000 for men and 89.1 and 64.1 per 100 000 for women. The association between family history of polyps and CRC risk was strengthened by the increasing number of first degree relatives with polyps (≥2 first degree relatives: 1.70, 1.52 to 1.90, P<0.001 for trend) and decreasing age at polyp diagnosis (<50 years: 1.77, 1.57 to 1.99, P<0.001 for trend). A particularly strong association was found for early onset CRC diagnosed before age 50 years (≥2 first degree relatives: 3.34, 2.05 to 5.43, P=0.002 for heterogeneity by age of CRC diagnosis). In the joint analysis, the odds ratio of CRC for individuals with two or more first degree relatives with polyps but no CRC was 1.79 (1.52 to 2.10), with one first degree relative with CRC but no polyps was 1.70 (1.65 to 1.76), and with two or more first degree relatives with both polyps and CRC was 5.00 (3.77 to 6.63) (P<0.001 for interaction).CONCLUSIONS: After adjusting for family history of CRC, the siblings and children of patients with colorectal polyps are still at higher risk of CRC, particularly early onset CRC. Early screening for CRC might be considered for first degree relatives of patients with polyps.

    • Background: Long-term colorectal cancer incidence and mortality after colorectal polyp removal remains unclear. We aimed to assess colorectal cancer incidence and mortality in individuals with removal of different histological subtypes of polyps relative to the general population.Methods: We did a matched cohort study through prospective record linkage in Sweden in patients aged at least 18 years with a first diagnosis of colorectal polyps in the nationwide gastrointestinal ESPRESSO histopathology cohort (1993-2016). For each polyp case, we identified up to five matched reference individuals from the Total Population Register on the basis of birth year, age, sex, calendar year of biopsy, and county of residence. We excluded patients and reference individuals with a diagnosis of colorectal cancer either before or within the first 6 months after diagnosis of the index polyp. Polyps were classified by morphology codes into hyperplastic polyps, sessile serrated polyps, tubular adenomas, tubulovillous adenomas, and villous adenomas. Colorectal cancer cases were identified from the Swedish Cancer Registry, and cause-of-death data were retrieved from the Cause of Death Register. We collected information about the use of endoscopic examination before and after the index biopsy from the Swedish National Patient Registry, and counted the number of endoscopies done before and after the index biopsies. We calculated cumulative risk of colorectal cancer incidence and mortality at 3, 5, 10, and 15 years, and computed hazard ratios (HRs) and 95% CIs for colorectal cancer incidence and mortality using a stratified Cox proportional hazards model within each of the matched pairs.Findings: 178 377 patients with colorectal polyps and 864 831 matched reference individuals from the general population were included in our study. The mean age of patients at polyp diagnosis was 58.6 (SD 13.9) years for hyperplastic polyps, 59.7 (14.2) years for sessile serrated polyps, 63.9 (12.9) years for tubular adenomas, 67.1 (12.1) years for tubulovillous adenomas, and 68.9 (11.8) years for villous adenomas. During a median of 6.6 years (IQR 3.0-11.6) of follow-up, we documented 4278 incident colorectal cancers and 1269 colorectal cancer-related deaths in patients with a polyp, and 14 350 incident colorectal cancers and 5242 colorectal cancer deaths in general reference individuals. The 10-year cumulative incidence of colorectal cancer was 1.6% (95% CI 1.5-1.7) for hyperplastic polyps, 2.5% (1.9-3.3) for sessile serrated polyps, 2.7% (2.5-2.9) for tubular adenomas, 5.1% (4.8-5.4) for tubulovillous adenomas, and 8.6% (7.4-10.1) for villous adenomas compared with 2.1% (2.0-2.1) in reference individuals. Compared with reference individuals, patients with any polyps had an increased risk of colorectal cancer, with multivariable HR of 1.11 (95% CI 1.02-1.22) for hyperplastic polyps, 1.77 (1.34-2.34) for sessile serrated polyps, 1.41 (1.30-1.52) for tubular adenomas, 2.56 (2.36-2.78) for tubulovillous adenomas, and 3.82 (3.07-4.76) for villous adenomas (p<0.05 for all polyp subtypes). There was a higher proportion of incident proximal colon cancer in patients with serrated (hyperplastic and sessile) polyps (52-57%) than in those with conventional (tubular, tubulovillous, and villous) adenomas (30-46%). For colorectal cancer mortality, a positive association was found for sessile serrated polyps (HR 1.74, 95% CI 1.08-2.79), tubulovillous adenomas (1.95, 1.69-2.24), and villous adenomas (3.45, 2.40-4.95), but not for hyperplastic polyps (0.90, 0.76-1.06) or tubular adenomas (0.97, 0.84-1.12).Interpretation: In a largely screening-naive population, compared with individuals from the general population, patients with any polyps had a higher colorectal cancer incidence, and those with sessile serrated polyps, tubulovillous adenomas, and villous adenomas had a higher colorectal cancer mortality.

  • Policies on children and schools during the SARS-CoV-2 pandemic in Western Europe
  • 2023
  • Ingår i: Frontiers in Public Health. - 2296-2565. ; 11
  • Forskningsöversikt (refereegranskat)abstract
    • During the pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), mitigation policies for children have been a topic of considerable uncertainty and debate. Although some children have co-morbidities which increase their risk for severe coronavirus disease (COVID-19), and complications such as multisystem inflammatory syndrome and long COVID, most children only get mild COVID-19. On the other hand, consistent evidence shows that mass mitigation measures had enormous adverse impacts on children. A central question can thus be posed: What amount of mitigation should children bear, in response to a disease that is disproportionally affecting older people? In this review, we analyze the distinct child versus adult epidemiology, policies, mitigation trade-offs and outcomes in children in Western Europe. The highly heterogenous European policies applied to children compared to adults did not lead to significant measurable differences in outcomes. Remarkably, the relative epidemiological importance of transmission from school-age children to other age groups remains uncertain, with current evidence suggesting that schools often follow, rather than lead, community transmission. Important learning points for future pandemics are summarized.

  • Association of inflammatory bowel disease in first-degree relatives with risk of colorectal cancer : A nationwide case-control study in Sweden
  • 2023
  • Ingår i: International Journal of Cancer. - : John Wiley & Sons. - 0020-7136 .- 1097-0215. ; 152:11, s. 2303-2313

    • This study aims to assess the association between inflammatory bowel disease (IBD) history in first-degree relatives (FDRs) and colorectal cancer (CRC) risk. We conducted a nationwide case-control study in Sweden among 69,659 CRC cases and 343,032 non-CRC controls matched on age, sex, birth year, and residence county. Through linkage of multi-generation register and the nationwide ESPRESSO (Epidemiology Strengthened by histoPathology Reports in Sweden) cohort, we ascertained IBD diagnoses among parents, full siblings, and offspring of the index individuals. Odds ratios (ORs) of CRC associated with IBD family history were calculated using conditional logistic regression. 2.2% of both CRC cases (1,566/69,659) and controls (7,676/343,027) had ≥1 FDR with IBD history. After adjusting for family history of CRC, we observed no increased risk of CRC in FDRs of IBD patients (OR, 0.96; 95%CI, 0.91-1.02). The null association was consistent according to IBD subtype (Crohn's disease or ulcerative colitis), number of FDRs with IBD (1 or ≥2), age at first IBD diagnosis in FDRs (<18, 18-39, 40-59, or ≥60 years), maximum location/extent of IBD, or FDR relation (parent, sibling, or offspring). The null association remained for early-onset CRC (diagnosed at age <50 years). In conclusion, IBD history in FDRs was not associated with an increased risk of CRC. Our findings suggest that extra screening for CRC may not be needed in the offspring, siblings, or parents of IBD patients, and strengthen the theory that it is the actual inflammation or atypia of the colon in IBD patients that confers the increased CRC risk.
