- Objective: To investigate the current prevalence of physician-diagnosed obstructive airway diseases by respiratory symptoms and by sex in Sweden and Finland. Method: In 2016, a postal questionnaire was answered by 34,072 randomly selected adults in four study areas: Västra Götaland and Norrbotten in Sweden, and Seinäjoki-Vaasa and Helsinki in Finland. Results: The prevalence of asthma symptoms was higher in Norrbotten (13.2%), Seinäjoki-Vaasa (14.8%) and Helsinki (14.4%) than in Västra Götaland (10.7%), and physician-diagnosed asthma was highest in Norrbotten (13.0%) and least in Västra Götaland (10.1%). Chronic productive cough was most common in the Finnish areas (7.7-8.2 % versus 6.3-6.7 %) while the prevalence of physician-diagnosed chronic bronchitis (CB) or chronic obstructive pulmonary disease (COPD) varied between 1.7-2.7% in the four areas. Among individuals with respiratory symptoms, the prevalence of asthma was most common in Norrbotten, while a diagnosis of COPD or CB was most common in Västra Götaland and Seinäjoki-Vaasa. More women than men with respiratory symptoms reported a diagnosis of asthma in Sweden and Seinäjoki-Vaasa but there were no sex differences in Helsinki. In Sweden, more women than men with symptoms of cough or phlegm reported a diagnosis of CB or COPD, while in Finland the opposite was found. Conclusion: The prevalence of respiratory symptoms and corresponding diagnoses varied between and within the countries. The proportion reporting a diagnosis of obstructive airway disease among individuals with respiratory symptoms varied, indicating differences in diagnostic patterns both between areas and by sex.

Tidskriftsartikel (refereegranskat)abstract
- V/P SPECT from 4 consecutive patients with COVID-19 suggests that ventilation and perfusion images may be applied to diagnose or exclude pulmonary embolism, verify nonsegmental diversion of perfusion from the ventilated areas (dead space ventilation) that may represent inflammation of the pulmonary vasculature, detect the reversed mismatch of poor ventilation and better preserved perfusion (shunt perfusion) in bilateral pulmonary inflammation and indicate redistribution of lung perfusion (antigravitational hyperperfusion) due to cardiac congestion. V/P mismatch and reversed mismatch may be extensive enough to diminish dramatically preserved matching ventilation/perfusion and to induce severe hypoxemia in COVID-19.

- Hepato-pulmonary shunts might develop in some patients with severe liver disease, usually when cirrhosis has developed. At this stage, a dilatation of intra-pulmonary vessels might develop causing defects in blood oxygenation. Shortness of breath is a common symptom. The disease might be asymptomatic but it has an impact of patient's quality of life. The identification of shunt dysfunction is based on the arterial blood gas test. The dilatation of pulmonary vessels and shunting index can be identified by macro aggregated albumin lung perfusion scintigraphy (99mTc-MAA) or a transthoracic contrast-enhanced echocardiography.

Ingår i: Nuclear Medicine and Molecular Imaging : Volume 1-4 - Volume 1-4. - 9780128229804 - 9780128229606 ; 2, s. 92-102

- Ventilation/perfusion single photon emission computed tomography (V/P SPECT) is the recommended method for proper diagnosis of pulmonary embolism (PE), according to the European Association of Nuclear Medicine (EANM) guidelines. Adequate V/P SPECT acquisition starts with ventilation and continues immediately with perfusion. The whole procedure takes 20min by using an optimal combination of nuclide activities, collimators, and imaging matrix. For the ventilation studies, Technegas particles have an advantage over radiolabeled liquid aerosols due to the better penetration to the periphery. Radiolabeled macro aggregated human albumin (MAA) is the imaging agent of choice for perfusion scintigraphy. The method allows recognition of V/P pattern typical for PE, the sign of chronic obstructive pulmonary disease (COPD), pneumonia, left heart failure (LHF), chronic PE, and suspicion of other parenchymal processes like tumors. It gives a clear answer to the clinicians regarding PE. Furthermore, it is possible to quantify the extent of ventilation and perfusion changes. The radiation exposure is low, the sensitivity and specificity are above 95% and the method has no contraindications. It is possible to diagnose PE even in the presence of another pulmonary comorbidity. Hybrid V/P SPECT/CT might have additional value for tumor diagnostics.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: Asthma may begin at any age. However, knowledge about the relationship between age at asthma diagnosis and asthma symptoms is still scarce.Objectives: To test the hypothesis that among adults, asthma diagnosed in adulthood is associated with more symptoms than asthma diagnosed in childhood.Methods: A FinEsS postal survey was conducted in a random sample of 16000 20-69-year-old adults in Finland in 2016. Age 18 years was chosen to delineate child and adult-diagnosed asthma. Current asthma was defined as physician-diagnosed asthma and asthma medication use, attacks of breathlessness or wheezing in the past year.Results: Of responders (8199, 51,5%), 692 reported current asthma and age at diagnosis. Adult-diagnosed asthma was reported by 445 (64.3%) and child-diagnosed by 247 (35.7%) responders. Those with adult-diagnosed asthma had more attacks of breathlessness in the past year (82.9% vs. 74.1%, p=0.006), dyspnea (mMRC grade ≥2) (34.4% vs. 18.8%, p<0.001) and sputum production in the past three consecutive months (40.0% vs. 27.5%, p=0.001). Of responders with adult and child-diagnosed asthma, 22.5% and 28.3% were current smokers, and 91.7% and 84.2% used asthma medication, respectively. In a logistic regression model, risk factors for attacks of breathlessness were adult-diagnosis (OR=1.8, 95% CI 1.1-3.0) and exercising <2 times a week (OR=2.0, 1.2-3.2).Conclusion: Asthmatics with adult-diagnosed asthma had significantly more symptoms even though they smoked less and used asthma medication more often compared to those with child-diagnosed asthma. Recognizing adult onset asthma in clinical practise is important to direct precise clinical care and achieve better asthma control.

Tidskriftsartikel (refereegranskat)abstract
- Background: Chronic nonrespiratory diseases are seemingly more prevalent in subjects with than without asthma, and asthma seems to differentiate by age of onset. However, studies with comparison of nonrespiratory diseases in subjects with and without asthma, considering asthma age of onset, are scarce.Objective: To compare the quantity and type of chronic nonrespiratory diseases in adults with and without asthma considering age at asthma diagnosis.Methods: In 2016, a FinEsS questionnaire was sent to 16,000 20- to 69-year-old adults randomly selected in Helsinki and Western Finland populations. Physician-diagnosed asthma was categorized to early (0-11), intermediate (12-39), and late-diagnosed (40-69 years).Results: A total of 8199 (51.5%) responded, and 842 (10.3%) reported asthma and age at diagnosis. In age and sex-adjusted binary logistic regression model, the most represented nonrespiratory disease was treated gastroesophageal reflux disease in early-diagnosed (odds ratio, 1.93; 95% CI, 1.17-3.19; P =.011) and osteoporosis in both intermediate-diagnosed (odds ratio, 3.45; 95% CI, 2.01-5.91; P <.001) and late-diagnosed asthma (odds ratio, 2.91; 95% CI, 1.77-4.79; P <.001), compared with subjects without asthma. In addition, gastroesophageal reflux disease, depression, sleep apnea, painful condition, and obesity were significantly more common in intermediate- and late-diagnosed asthma compared with without asthma, and similarly anxiety or panic disorder in intermediate-diagnosed and hypertension, severe cardiovascular disease, arrhythmia, and diabetes in late-diagnosed asthma. In age-adjusted analyses, having 3 or more nonrespiratory diseases was more common in intermediate (12.1%) and late-diagnosed asthma (36.2%) versus without asthma (10.4%) (both P <.001).Conclusions: Nonrespiratory diseases were more common in adults with asthma than in adults without asthma. The type of nonrespiratory diseases differed, and their frequency increased by increasing age at asthma diagnosis.

- Objectives Our objective was to study mortality related to different obstructive lung diseases, occupational exposure, and their potential joint effect in a large, randomized population-based cohort. Methods We divided the participants based on the answers to asthma and chronic obstructive pulmonary disease (COPD) diagnoses and occupational exposure and used a combined effects model and compared the results to no asthma or COPD with no occupational exposure. Results High exposure had a hazards ratio (HR) of 1.34 (1.11-1.62) and asthma and COPD coexistence of 1.58 (1.10-2.27). The combined effects of intermediate exposure and coexistence had an HR of 2.20 (1.18-4.09), high exposure with coexistence of 1.94 (1.10-3.42) for overall mortality, and sub-HR for respiratory-related mortality of 3.21 (1.87-5.50). Conclusions High occupational exposure increased overall but not respiratory-related mortality hazards, while coexisting asthma and COPD overall and respiratory-related hazards of mortality.

- Objective: To study occupational groups and occupational exposure in association with chronic obstructive respiratory diseases.Methods: In early 2000s, structured interviews on chronic respiratory diseases and measurements of lung function as well as fractional expiratory nitric oxide (FENO) were performed in adult random population samples of Finland, Sweden and Estonia. Occupations were categorized according to three classification systems. Occupational exposure to vapours, gases, dusts and fumes (VGDF) was assessed by a Job-Exposure Matrix (JEM). The data from the countries were combined.Results: COPD, smoking and occupational exposure were most common in Estonia, while asthma and occupations requiring higher educational levels in Sweden and Finland. In an adjusted regression model, non-manual workers had a three-fold risk for physician-diagnosed asthma (OR 3.18, 95%CI 1.07-9.47) compared to professionals and executives, and the risk was two-fold for healthcare & social workers (OR 2.28, 95%CI 1.14-4.59) compared to administration and sales. An increased risk for physician-diagnosed COPD was seen in manual workers, regardless of classification system, but in contrast to asthma, the risk was mostly explained by smoking and less by occupational exposure to VGDF. For FENO, no associations with occupation were observed.Conclusions: In this multicenter study from Finland, Sweden and Estonia, COPD was consistently associated with manual occupations with high smoking prevalence, highlighting the need to control for tobacco smoking in studies on occupational associations. In contrast, asthma tended to associate with non-manual occupations requiring higher educational levels. The occupational associations with asthma were not driven by eosinophilic inflammation presented by increased FENO.

- Purpose: Environmental particulate matter (PM) exposure has been shown to cause excess all-cause and disease-specific mortality. Our aim was to compare disease-specific mortality by estimated occupational exposure to vapors, gasses, dusts, and fumes (VGDF).Methods: The data source is the Helsinki part of the population-based FinEsS study on chronic obstructive pulmonary diseases including information on age, education level, main occupation, sex, and tobacco smoking combined with death registry information. We compared estimated VGDF exposure to mortality using adjusted competing-risks regression for disease-specific survival analysis for a 24-year follow-up.Results: Compared to the no-exposure group, the high occupational VGDF exposure group had sub-hazard ratios (sHR) of 1.7 (95% CI 1.3–2.2) for all cardiovascular-related and sHR 2.1 (1.5–3.9) for just coronary artery-related mortality. It also had sHR 1.7 (1.0–2.8) for Alzheimer’s or vascular dementia-related mortality and sHR 1.7(1.2–2.4) for all respiratory disease-related mortality.Conclusion: Long-term occupational exposure to VGDF increased the hazard of mortality- to cardiovascular-, respiratory-, and dementia-related causes. This emphasizes the need for minimizing occupational long-term respiratory exposure to dust, gasses, and fumes.
