- OBJECTIVE: Occupational quartz exposure is a health risk, with increased risk of developing lung, autoimmune diseases, and elevated mortality in cardiovascular diseases.METHODS: The population was obtained from the period 2005 to 2016 and consisted of 5237 cases of patients with atrial fibrillation (AF). Quartz exposure information was obtained through a Swedish job exposure matrix.RESULTS: The risk of developing AF was increased for the quartz-exposed male population who were within a year of having commenced employment OR 1.54; (95% CI 1.06-2.24); this increased in the age group 20 to 55 (OR 2.05; CI 95% 1.02-4.10).CONCLUSION: Our main conclusion is that quartz dust exposure may be related to increased risk of AF in high exposed (above 0.05 mg/m mean quartz dust) in men aged 20 to 55 years.

- Methods: Total dust was sampled in the breathing zone of 73 subjects working with welding, cutting, grinding and in foundries such as iron, aluminium, and concrete. Stationary measurements were used to study different size fractions of particles including respirable dust, particulate matter (PM)(10) and PM2.5, the particle number concentration, the number of particles deposited in the alveoli, and total particle surface area concentration. Inflammatory markers such as interleukin-6 (IL-6), C-reactive protein (CRP), fibrinogen, D-dimer, and urate were measured in plasma or serum before the first shift after the summer vacation and after the first, second, and fourth shift. Results: The mean level of total dust in the breathing zone was 0.93 mg/m

- Whether patients with non-functioning pituitary adenoma (NFPA) are at increased risk of developing malignant tumours has been sparsely studied and is a matter of debate. In this study, we have investigated the incidence of malignant tumours in a large and unselected group of patients with NFPA. The study was nationwide and included all patients diagnosed with NFPA between 1987 and 2011 (n = 2795) in Sweden, identified in the National Patient Register. Malignant tumours, occurring after the NFPA diagnosis, were identified in the Swedish Cancer Register between 1987 and 2014. Standardised incidence ratios (SIRs) for malignant tumours with 95% confidence intervals (CI) were calculated using the Swedish population as reference. In total, 448 malignant tumours were detected in 386 patients with NFPA, as compared to 368 expected malignancies in the general population (SIR 1.22 (95% CI 1.11-1.33)). The incidence of neoplasms of the brain was increased (SIR 5.83 (95% CI 4.03-8.14)). When analysing the total incidence of malignancies excluding neoplasms of the brain, the overall SIR was still increased (SIR 1.14 (95% CI 1.03-1.26)). The incidence of malignant neoplasm of skin other than malignant melanoma (SIR 1.99 (95% CI 1.55-2.52)) and malignant melanoma (SIR 1.62 (95% CI 1.04-2.38)) were increased, whereas the incidence of breast cancer (SIR 0.65 (95% CI 0.42-0.97)) was decreased. The incidence of other types of malignancies did not differ significantly from the expected incidence in the general population. In conclusion, patients with NFPA have an increased overall risk of developing malignancies. To what extent these findings are due to more frequent medical surveillance, genetic predisposition or endocrine changes, remains unknown.

- Hypopituitarism has been associated with increased mortality. The excess mortality may be due to untreated growth hormone (GH) deficiency but also due to various underlying disorders. We therefore analysed mortality in patients with only one underlying disorder, non-functioning pituitary adenoma (NFPA), with and without GH replacement therapy (GHRT).Patients with NFPA in the western region of Sweden, 1997-2011, were identified through the National Patient Registry and cross-referenced with several National Health Registries. All patient records were reviewed. Standardised mortality ratios (SMRs) with 95% confidence intervals (CIs) were calculated using the general population as reference. Cox-regression models were performed to identify predictors of mortality.A total of 426 NFPA patients with 4599 patient-years were included, of whom 207 had used GHRT and 219 had not received GHRT. Median (range) follow-up in patients with and without GHRT was 12.2 (0-25) and 8.2 (0-27) years, respectively. Other pituitary hormone deficiencies were more frequent in the GHRT group than those in the non-GHRT group. SMR was 0.65 (95% CI, 0.44-0.94; P=0.018) for the GHRT group and 1.16 (0.94-1.42; P=0.17) for the non-GHRT group. Direct comparison between the groups showed reduced mortality among those who were GH replaced (P=0.0063). The SMR for malignant tumours was reduced in the GHRT-group (0.29; 0.08-0.73; P=0.004) but not in untreated patients.Selection bias explaining some of the results cannot be excluded. However, NFPA patients with GHRT had reduced overall mortality compared with the general population, and death due to malignancy was not increased. This suggests that long-term GHRT is safe in adult patients selected for treatment.

- PURPOSE: Patients with non-functioning pituitary adenomas (NFPA), especially women, have increased mortality. The aim of this study was to investigate whether mortality in NFPA patients has changed during the last two decades.METHODS: This was a nationwide population-based study including 2795 patients (1502 men, 1293 women) diagnosed with NFPA between 1997 and 2011. Patients were identified and followed in Swedish National Health Registries. Standardized mortality ratios (SMRs) with 95 % confidence intervals were calculated for three time periods at first NFPA diagnosis using the general population as reference.RESULTS: Mean (±SD) age at NFPA diagnosis was 58.9 ± 16.8 years. Mean (range) follow-up time was 8.3 (0-18) years, resulting in 20,517 patient-years at risk. Surgical treatment and radiotherapy were used in 53 and 5 %, respectively. The prevalence of hypopituitarism was 64 % during the first time period of diagnosis and then declined gradually during the study period (P value for trend <0.0001). The use of pituitary surgery and radiotherapy remained stable. In women, mortality was increased for patients diagnosed between 1997 and 2006 but not for those diagnosed between 2007 and 2011. The SMR in men remained stable throughout the study and did not differ from the general population. During the last time period, 2007-2011, the SMR between men and women did not differ.CONCLUSIONS: While mortality in men with NFPA remains normal and stable during the last two decades, mortality in women has declined. Decreasing prevalence of pituitary insufficiency may be a plausible explanation for this positive development.

- Context: Whether multisystem morbidity in Cushing's disease (CD) remains elevated during long-term remission is still undetermined.Objective: To investigate comorbidities in patients with CD.Design, setting, and patients: A retrospective, nationwide study of patients with CD identified in the Swedish National Patient Register between 1987 and 2013. Individual medical records were reviewed to verify diagnosis and remission status.Main outcomes: Standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) were calculated by using the Swedish general population as reference. Comorbidities were investigated during three different time periods: (i) during the 3 years before diagnosis, (ii) from diagnosis to 1 year after remission, and (iii) during long-term remission.Results: We included 502 patients with confirmed CD, of whom 419 were in remission for a median of 10 (interquartile range 4 to 21) years. SIRs (95% CI) for myocardial infarction (4.4; 1.2 to 11.4), fractures (4.9; 2.7 to 8.3), and deep vein thrombosis (13.8; 3.8 to 35.3) were increased during the 3-year period before diagnosis. From diagnosis until 1 year after remission, SIRs (95% CI were increased for thromboembolism (18.3; 7.9 to 36.0), stroke (4.9; 1.3 to 12.5), and sepsis (13.6; 3.7 to 34.8). SIRs for thromboembolism (4.9; 2.6 to 8.4), stroke (3.1; 1.8 to 4.9), and sepsis (6.0; 3.1 to 10.6) remained increased during long-term remission.Conclusion: Patients with CD have an increased incidence of stroke, thromboembolism, and sepsis even after remission, emphasizing the importance of early identification and management of risk factors for these comorbidities during long-term follow-up.

- PURPOSE: Myopia is the most important risk factor for developing retinal tears and retinal detachment (RD). Due to altered lifestyle factors myopia is increasing in the world. In this study, the correlation between educational level and risk for retinal detachment were analysed.METHODS: A case-control registry study was conducted including a total of 10 268 individuals. Data were collected from registries of the Swedish National Board of Health and Welfare as well as the Swedish Central Bureau of Statistics. Cases were defined as ICD-10 H33 (retinal detachments and breaks). For each case, a matched control was selected with the same age and sex, living in the same county at the time of diagnosis. The study population was divided into seven groups with regard to educational level and compared using conditional logistic regression.RESULTS: In the total population, the odds ratio (OR) increased in a proportional fashion with a higher level of education. The odds ratio for the total population at the highest education level was 1.77 and increased to 2.00 when excluding individuals with diabetes. Out of the 5134 cases, 72% were men and 28% women. A statistically significant difference between sexes was only confirmed for the second highest education level.CONCLUSION: Individuals with a longer education have a significantly higher risk for retinal complications in the form of RD and breaks. Higher education is a risk factor for retinal complications in both sexes but seemingly more strongly in men.

Do Some Patients Younger Than 65 Years Old And With Incident Atrial Fibrillation Need Anticoagulation Treatment? : Conclusions From A Swedish Nationwide Registry Study
- 2018
-
Konferensbidrag (refereegranskat)abstract
- Background: It is still under debate whether patients with atrial fibrillation (AF) and a low risk of cerebral infarction would benefit from anticoagulation.Objective: We aimed to assess whether younger patients with AF and lower CHA2DS2-VASc score would benefit from anticoagulation treatment.Methods: In a retrospective, nationwide cohort study, using the Swedish national registries, 59981 hospitalized patients were identified with incident AF. After exclusion of 11548 patients because of warfarin use before the AF diagnosis, or death, emigration or stroke within 30 days of AF diagnosis, the remaining 48 433 patients, among whom 27166 patients had no warfarin treatment, were, after adjustment for age, sex and year of AF diagnosis, divided according to age, sex and CHA2DS2-VASc score 0, 1, 2 and ≥3 and included in a time-varying analysis of warfarin treatment versus no treatment. Patients were followed up to 48 months after the inclusion.Results: In men <65 years and with a CHA2DS2-VASc score 2 or ≥3, the relative risk of having a stroke or cerebral infarction was lower when they received warfarin treatment, HR 0.35 (95% CI 0.18-0.69) and HR 0.37 (95% CI 0.23-0.59) respectively, as compared to HR 1.11 (95% CI 0.56-2.23) when the score was 1. Women younger than 65 years had a low relative risk when CHA2DS2-VASc score was ≥3 points, HR 0.31 (95% CI 0.16-0.59), as compared to HR 1.84 (95% CI 0.86-3.94) and HR 2.13 (95% CI 0.94-4.84) when the score was 2 and 1 respectively. The risk of intracranial bleeding was low and similar in all subgroups on anticoagulation except in the youngest men without risk factors.Conclusion: Women and men <65 years had a beneficial effect of warfarin if they had two risk factors other than age and sex, without an increased risk of bleeding. Our results support prophylactic anticoagulation treatment in patients under 65 years and a CHA2DS2-VASc score ≥2, other than age and sex.

Tidskriftsartikel (refereegranskat)abstract
- Context: Whether patients with Cushing disease (CD) in remission have increased mortality is still debatable. Objective: To study overall and disease-specific mortality and predictive factors in an unselected nationwide cohort of patients with CD. Design, Patients, and Methods: A retrospective study of patients diagnosed with CD, identified in the Swedish National Patient Registry between 1987 and 2013. Medical records were systematically reviewed to verify the diagnosis. Standardized mortality ratios (SMRs) with 95% CIs were calculated and Cox regression models were used to identify predictors of mortality. Results: Of 502 identified patients with CD (n = 387 women; 77%), 419 (83%) were confirmed to be in remission. Mean age at diagnosis was 43 (SD, 16) years and median follow-up was 13 (interquartile range, 6 to 23) years. The observed number of deaths was 133 vs 54 expected, resulting in an overall SMR of 2.5 (95% CI, 2.1 to 2.9). The commonest cause of death was cardiovascular diseases (SMR, 3.3; 95% CI, 2.6 to 4.3). Excess mortality was also found associated with infections and suicide. For patients in remission, the SMR was 1.9 (95% CI, 1.5 to 2.3); bilateral adrenalectomy and glucocorticoid replacement therapy were independently associated with increased mortality, whereas GH replacement was associated with improved outcome. Conclusion: Findings from this large nationwide study indicate that patients with CD have excess mortality. The findings illustrate the importance of achieving remission and continued active surveillance, along with adequate hormone replacement and evaluation of cardiovascular risk and mental health.
