Quo vadis, the leading arrhythmia? Projecting the prevalence of atrial fibrillation up to 2070

Abstract Introduction The prevalence of atrial fibrillation (AF) is strongly associated with age, and with increasing life expectancy worldwide, the number of AF patients has been steadily rising. However, long-term projections of AF prevalence are scarse. Purpose To predict the prevalence and the number of patients with AF in Finland from 2021 until 2070. Methods In the Finnish Anticoagulation in Atrial Fibrillation (FinACAF) study we gathered data of all AF patients from all national health care registers (hospitalizations and outpatient specialist visits, primary health care contacts, and reimbursements for prescription medicines) from 2004 to 2018. The prevalence of AF on December 31st 2018 was calculated as the number of patients alive with AF divided by the number of Finnish population. We utilized age- and sex-specific prevalences on year 2018 to predict the prevalence by sex and 5-year age groups, using a 1-year time interval of AF in Finland between years 2021 and 2070. We obtained the projection for population structure in Finland between 2021 and 2070 from Statistics Finland. The prevalences in 2070 are provided for population ≥20 years as well as for populations ≥65 years, ≥75 years, and ≥85 years. Results In 2018, a total of 226 847 patients with the diagnosis of AF were documented in Finland. The number of adult patients with AF is predicted to increase strongly up to 2040 with a slower increase from 2040 to 2060, and again a faster increase is estimated from 2060 up to our final estimation of 2070. In total, the number of AF patients will increase with 60% until the year 2070. In 2021, prevalence of AF was 5.5% in adults and prevalence rate will increase to 8.6% in 2070. Proportion of men will be from 54.7 % to 56.0%, and the prevalence will be higher in men compared to women in all age groups with the exception in the age group ≥85 years. Among the population ≥65 years the prevalence in 2070 will be 19.7 %, and in the elderly, ≥75 years, the prevalence of AF will 25.6% and in the oldest, ≥85 years, 31.7%. In 2070 73.3 % of patients with AF are over 75 years, and 38.8% are over 85 years old. Conclusions Drawing upon extensive nationwide data covering all levels of care, our estimates indicate a continual rise in the number of AF patients in Finland until the year 2070. Notably, throughout the projected period, there is a discernible increase in the proportion of older and the oldest patients, highlighting the demographic shift in AF prevalence.Patients with AF 2021-2070 in Finland

Integration of Power to X Economy in Existing Energy System – Case Finland

Hydrogen or Power-to-X economy is seen as the most promising way to carry out the energy transition from fossil to renewable carbon free energy system. Electrification of the society and green hydrogen-based energy system require huge capacity increase in renewable energy production and energy transmission. This paper introduces a simulation study about the integration of green hydrogen-based energy system to existing power system structure in Finland. Regional energy balances are studied with different options of locations of renewable energy and hydrogen production plants and needs for energy transportation either as electricity or hydrogen. The model includes sectoral couplings between electricity, hydrogen and heating grids and finds synergies of flexibility between different energy grids.

Individual tree basal area increment models suitable for different stand structures in Finland

Forest growth models employed in Fennoscandia have been generally targeted at rotation forestry (RF) stands, relying on age as a key predictor. Uneven aged, irregular stands, such as the ones managed with continuous cover forestry, are becoming of increasingly common. New models suited for all kind of management approaches (i.e., age-independent) have been developed in Fennoscandia. Although the ongoing climate change is projected to strongly affect tree growth in boreal regions, climatic variables included in current models are usually restricted to temperature sum averages with simple links.The objectives of our research were: 1) fitting a new age independent empirical tree basal area increment model (B2023) with inclusion of additional climatic variables for the main Nordic tree species (Norway spruce, Scots pine, and birches); 2) using independent data to validate both the new model and other two age-independent published empirical models (P2013, P2021); and 3) investigating the sensitivity of growth predictions of all the empirical models to climate change.Our results showed that the new model B2023 was as accurate as P2013 when independently validated. Both models performed well in different forest structures and management alternatives (namely rotation forestry, continuous cover forestry, two-storied stands, and old-growth natural forests), although with few differences, and on average slightly better than P2021. At plot level, the new model B2023 showed slight underprediction for the overstorey pine layer in continuous cover forestry and two-storied stands. The predicted climate change scenarios increased simulated growth in all models, although P2021 showed very high values for spruce. We failed to include additional climatic variables than temperature sum in B2023, thus not improving much its accuracy under historical data, nor its sensitivity to future climate.Concluding, the individual tree models here presented can be applied to a wide range of forest structures and managements in Fennoscandia. For long-term simulation scenarios, different approaches to improve the climate sensitivity of empirical, individual tree model should be explored.

Aluerakenne, alueellinen erivertaisuus ja Suomen aluekehitys

In this paper we draw on the work of Doreen Massey and David Harvey and think with the concept of spatial structure. We divide the concept into three constitutive elements: uneven geographical development (materiality), the discursive production of spatial structures (semiosis) and collective politics of spatial structure (experience). We conclude our argument with the concept of relational inequality and a call for rigorous examination of the history and current development of spatial structures in Finland and elsewhere from the perspective of the threefold conceptual frame presented in the paper.

Multi-local living and spatial interaction are expected to change the picture of regional development, as they emphasize the seasonal and interrelated use of areas. The article focusses on questions: What kind of spatial formation is the regional structure in Finland divided, and how common are these spatial formations in the regional structure? The results from the spatial cluster analysis show that the development of the regional structure is more diverse than previously known. Geographically, the dominating areas are seasonally growing areas which had remarkable increase in the seasonal use of areas. The results also showed that growth was more common in the regional structure than previously known, and the growth network extended from southern Finland to Lapland. The spatial formation of the stagnating areas was previously known to be narrower and more fragmented, as only a quarter of the surface area was classified as stagnating areas. The identifying of the diversity of the regional structure is essential for producing an exact picture of regional development for the needs of regional development and policy.

Relationship between socio-demographic and economic determinants of cause-specific mortality in the EU countries in the period 2011 – 2014

The article focuses on determinants of mortality and evaluates selected socio-demographic and economic sets of indicators. Our data matrix includes 112 observations for the EU28 countries in the period 2011 – 2014 (5 indicators of socio-demographic and economic determinants of health and 5 indicators of standardized cause-specific mortal-ity). The data is calculated using canonical correlation analysis, composite indicator and multiple regressions. Computed cause-specific mortality index shows most favourable mortality structures in Finland and France and unfavourable in Hungary. The correla-tions between socio-demographic, economic determinants and cause-specific mortality in the EU countries exist on the following levels. In the countries with very high GDP per capita generally people less often die of circulation disorders (e.g., Finland, France, Ger-many) and with lower GDP per capita it shows higher mortality rates relate to circulation system disorders and diabetes (e.g., Estonia, Lithuania, Hungary). In the countries with lower levels of educational attainment, people generally most often die of circulation dis-orders (e.g., Czech Republic, Slovakia, Italy) and people with higher educational attain-ment more often die of disease of nervous system (e.g., Finland, Belgium, Denmark). The levels of socio-demographic and economic determinants and the mortality structures correlate in the EU countries, but show different quality. The regional disparities in cause-specific mortality still persist between the countries of the northern, the western and the southern Europe. An unfavourable rate mortality was further affirmed in eastern and south-eastern Europe.

Intensive forest management — does it pay off financially on drained peatlands?

There are only a few studies focusing on the financial aspects of management regimes on peatland forests and even fewer studies investigating intensive management. Such studies, however, are urgently needed, particularly in Finland, where a considerable proportion of drained peatlands is reaching a phase requiring active management. An empirical data set derived from the 10th National Forest Inventory (NFI10) is applied for stand-level simulations (MOTTI stand simulator) until final cut. The data are a representative sample of the most common drained peatland site types and their current stand structures in Finland. Based on several different initial stand conditions, tree growth was projected according to four management regimes: (1) passive management (only one clearcut executed), (2) management according to prevailing silvicultural recommendations, (3) stand-level optimum without ditch network maintenance (DNM) and fertilization (FERT), and (4) stand-level optimum with DNM and FERT (intensive management). The intensive management regime financially outperformed the other management options distinctively, regardless of the climatic region, peatland site type, and initial stand structure. However, towards more harsh climatic conditions and a more barren site type, the financial difference between management options flattened out, and silvicultural recommendations even resulted in a higher mean annual increment (MAI) compared with intensive management.

Preferable utilisation patterns of wood product industries' by-products in Finland

We explored varying preferable utilisation patterns of wood product industries' by-products, and which actions are needed to implement them. We: (i) concluded scenarios with varying justifications in Finland towards 2030; (ii) analysed the key drivers and barriers, and (iii) evaluated the likelihood of these scenarios, and their advantages and disadvantages. The study adopted a scenario analysis approach using qualitative and quantitative data, where the industry, research, interest groups, and policy experts formed and reviewed the scenarios. The scenarios were compiled by grouping similar opinions by using cluster analysis, and the qualitative content was synthesised by using a futures table, yielding three scenarios: (I) Pulp and Bioenergy; (II) Versatile uses; and (III) Long-lifetime products. In scenario I, closest to the current industry structure in Finland, the aim was to respond to existing needs. Scenario II suggested material circulation and economic risk diversification, and fossil-to-bio substitution potential, but experts considered it less probable to implement by 2030. Scenario III highlighted the long-term carbon storage in wood products, but was perceived as the most unlikely, due to significant technical and market requirements related to a massive shift from energy to long-lifetime products. The main drivers across all scenarios relate to international policy, investment in R&D, and cross-sectoral cooperation to boost material- and energy efficiency. Policies need to set more explicitly the targets behind the utilisation of by-products, but consider the industry structure dynamics too. The study points to a need for industrial transformations towards ambitious circulation, and smart regulation encouraging markets towards the targets.

Optimal Coordination of Aggregated Hydro-Storage with Residential Demand Response in Highly Renewable Generation Power System: The Case Study of Finland

Current energy policy-driven targets have led to increasing deployment of renewable energy sources in electrical grids. However, due to the limited flexibility of current power systems, the rapidly growing number of installations of renewable energy systems has resulted in rising levels of generation curtailments. This paper probes the benefits of simultaneously coordinating aggregated hydro-reservoir storage with residential demand response (DR) for mitigating both load and generation curtailments in highly renewable generation power systems. DR services are provided by electric water heaters, thermal storages, electric vehicles, and heating, ventilation and air-conditioning (HVAC) loads. Accordingly, an optimization model is presented to minimize the mismatch between demand and supply in the Finnish power system. The model considers proportions of base-load generation comprising nuclear, and combined heat and power (CHP) plants (both CHP-city and CHP-industry), as well as future penetration scenarios of solar and wind power that are constructed, reflecting the present generation structure in Finland. The findings show that DR coordinated with hydropower is an efficient curtailment mitigation tool given the uncertainty in renewable generation. A comprehensive sensitivity analysis is also carried out to depict how higher penetration can reduce carbon emissions from electricity co-generation in the near future.

IS POLAND BECOMING NORDIC? CHANGING TRENDS IN HOUSEHOLD STRUCTURES IN POLAND AND FINLAND WITH THE EMPHASIS ON PEOPLE LIVING ALONE

Abstract This paper presents a comparative analysis of the household structure and its dynamics between post-economic-transformation Poland and Scandinavian-welfare-state Finland, with a focus on one-person households (OPH). Based on the literature, two research hypotheses were formulated: (H1) strong differences in the household structure in Finland and Poland still occur, and (H2) the share of one-person households is at very different levels in the two countries. However, due to the globally growing popularity of solo living, the difference is diminishing. Finally, an estimate was made for the time when the shares of one-person households will be equal in both countries if the changing trends from 2005–2015 stay the same. The first research hypothesis was proven to be correct. Small, one- or two-person households dominate the household structure in Finland, while in Poland the household structure by size was considerably more balanced. The second hypothesis was confirmed only partially. The share of OPH among all the households in 2015 was significantly larger in Finland (42%) than in Poland (24%). However, the difference between the countries was not diminishing. The share in Finland is increasing, while it is decreasing in Poland. This allowed the assumption that if the changing trends from the studied period are maintained, the shares of OPH in the two countries will not equalize, but will instead grow further apart. An estimate was made that in 2030 46% of Finnish households and 22% of Polish households will be one-person households.

Fine-Scale Genetic Structure in Finland.

Coupling dense genotype data with new computational methods offers unprecedented opportunities for individual-level ancestry estimation once geographically precisely defined reference data sets become available. We study such a reference data set for Finland containing 2376 such individuals from the FINRISK Study survey of 1997 both of whose parents were born close to each other. This sampling strategy focuses on the population structure present in Finland before the 1950s. By using the recent haplotype-based methods ChromoPainter (CP) and FineSTRUCTURE (FS) we reveal a highly geographically clustered genetic structure in Finland and report its connections to the settlement history as well as to the current dialectal regions of the Finnish language. The main genetic division within Finland shows striking concordance with the 1323 borderline of the treaty of Nöteborg. In general, we detect genetic substructure throughout the country, which reflects stronger regional genetic differences in Finland compared to, for example, the UK, which in a similar analysis was dominated by a single unstructured population. We expect that similar population genetic reference data sets will become available for many more populations in the near future with important applications, for example, in forensic genetics and in genetic association studies. With this in mind, we report those extensions of the CP + FS approach that we found most useful in our analyses of the Finnish data.

DSO tariff structures: development options from stakeholders’ viewpoint

Purpose – The purpose of the paper is to analyze the development needs and opportunities in the distribution system operators’ (DSO) tariff structures in the smart-grid environment. Design/methodology/approach – The impacts of the distribution pricing schemes for the stakeholders and their requirements for the tariff structures are evaluated by qualitative analyses. Furthermore, there is a case analysis concerning the practical development possibilities of the DSO tariff structures in Finland. Findings – Major finding of the paper is that the demand-based power band tariff is the optimal solution for the DSO pricing structure, when taking into account the real-life limitations and the requirements of the stakeholders. Practical implications – Outcomes of the paper can be applied in practice in design of the pricing schemes in the electricity distribution. Incentive provision impacts and cost reflectivity of the DSO tariffs can be improved by implementing the suggested pricing structure. Originality/value – The paper provides a novel viewpoint on the study of the DSO tariff design by considering the impacts of the pricing for the stakeholders and their requirements for tariff structure. Furthermore, the real-life limitations in the tariff design have been taken into account by analyzing the development options in Finland. Results are useful, especially for the DSOs, regulators and academics, who are working with the tariff development issues.

Geographical gradients in boreal forest albedo and structure in Finland

Land surface albedo is an essential climate variable controlling the planetary radiative energy budget, yet it is still among the main uncertainties of the radiation budget in the current climate modeling. To date, albedo satellite products have not been linked to extensive forest inventory data sets due to the lack of ground reference data. Here, we used comprehensive and detailed maps of forest inventory variables to couple forest structure and MODIS albedo products for both winter and summer conditions. We investigated how the relationships between forest variables and albedo change seasonally and along latitudinal gradients in the forest biomes of Finland between 60° and 70° N. We observed an increase in forest albedo with increasing latitude in winter but not in summer. Also, relationships between forest variables and the black-sky albedo or directional–hemispherical reflectance (DHR) at different latitudes were tighter in winter than in summer, especially for forest biomass. Summer albedo was only weakly correlated with the traditional inventory variables. Our findings suggest that the relationships between forest variables and DHR depend on latitude.

Changing objectives of non-industrial private forest ownership: a confirmatory approach to measurement model testing

While the behavior and objectives of non-industrial private forest (NIPF) owners have been studied extensively, studies that systematically test the underlying measurement model are lacking in forest economic literature. Our paper reports the results obtained from a recent large-scale survey conducted in Finland in 2011 (n = 557). Results indicate a novel way to systematically analyze the objectives of forest ownership by testing the validity of the developed measurement scale using the structural equations modeling technique. From an exploratory factor analysis of 22 items measuring forest owner objectives, a four-dimensional structure is identified in the background objectives of NIPF owners. These dimensions are labeled as recreation and leisure time, sense of economic security, nature conservation and aesthetics, and timber sales income objective. Having undergone a confirmatory testing process, results from the four-dimensional model support the validity of the developed 16-item measurement model. Based on these findings, we argue that the logical NIPF owner objective structure in Finland consists of experiential forest value, as perceived in current and future time contexts, as well as of current and future economic objectives. As the theoretical structure divides forest owner objectives into the evaluation of the present objectives, supplemented with a psychological evaluation of the future objectives, a novel classification of NIPF owner objectives is suggested.

Molecular Epidemiology of Tuberculosis in Finland, 2008-2011

In industrialized countries the majority of tuberculosis (TB) cases are linked to immigration. In Finland, most cases are still Finnish born but the number of foreign born cases is steadily increasing. In this 4-year population based study, the TB situation in Finland was characterized by a genotypic analysis of Mycobacterium tuberculosis isolates. A total of 1048 M. tuberculosis isolates (representing 99.4% of all culture positive cases) were analyzed by spoligotyping and MIRU. Spoligotype lineages belonging to the Euro-American family were predominant among the Finnish isolates, particularly T (n=346, 33.0%) and Haarlem (n=237, 22.6%) strains. The lineage signature was unknown for 130 (12.4%) isolates. Out of the 17 multi-drug resistant TB strains, 10 (58.8%) belonged to the Beijing lineage. In total, 23 new SIT designations were given and 51 orphan strains were found, of which 58 patterns were unique to Finland. Phylogeographical TB mapping as compared to neighboring countries showed that the population structure in Finland most closely resembled that observed in Sweden. By combining spoligotyping and MIRU results, 98 clusters comprising 355 isolates (33.9%) were found. Only 10 clusters contained both Finnish and foreign born cases. In conclusion, a large proportion of the M. tuberculosis isolates were from Finnish born elderly patients. Moreover, many previously unidentified spoligotype profiles and isolates belonging to unknown lineages were encountered.

Shock metamorphic features in quartz grains from the Saarijärvi and Söderfjärden impact structures, Finland

AbstractShock metamorphic features at the Saarijärvi (D > 2 km) and Söderfjärden (D = 6.5 km) structures in Finland have so far only been studied tentatively, although both are considered to be proven impact structures. This work presents the first detailed universal stage study of planar deformation features (PDFs), feather feature lamellae (FFL), and planar fractures (PFs) in quartz grains from a polymict impact breccia dike from Söderfjärden, and from sedimentary crater‐fill rocks from Saarijärvi. Planar microstructures, particularly PDFs, are very rare and poorly developed or preserved in Saarijärvi, whereas in Söderfjärden they are much more common and well defined. Miller–Bravais indices of the planar microstructures in both Saarijärvi and Söderfjärden are indicative of relatively low‐shock pressure but high shear conditions, only compatible with an impact origin for these structures. Although a Proterozoic age for Saarijärvi cannot be ruled out, the observations of shock features throughout the sedimentary crater‐fill sequence and a brecciated sedimentary dike below the crater floor are more consistent with a Lower Cambrian (or younger) impact age.

Threat of mass resignation as a window of opportunity for questioning hospital service production structures in Finland

BackgroundService production structures of public health care, once established, have proved extremely difficult to change. For this study, we reviewed discussions that took place in management teams at a Finnish central hospital over a period of nine months. The aim of the research was to analyze whether the management team meetings brought forth new and radical alternatives as to how service production could be reorganized. In addition to this, we were also interested in any possible problems that could be solved using these alternative models of service production, and also how preconditions to the application of different alternatives came about and how they eventually concluded.MethodsOur data were derived from 24 management team meetings that took place between August 2007 and May 2008, and were fully videotaped. Data were collected from eight different management teams; the meetings of each were videotaped three times. The management teams reviewed represented three different hierarchical levels, ie, top management, division management, and operational unit management. Data were analyzed according to theory-based content analysis. As a theoretical framework, we utilized Kingdon’s model to enable us to understand why some issues and problems are brought to the agenda of the change process and go on to become concrete policies while others fail to do so.ResultsDuring the study period, a threat of mass resignation of nursing staff caused a considerable change to the agenda of the management team meetings, introducing alternatives with the potential to renew the existing structures of operation in a radical manner.ConclusionAccording to our analysis, the threat of mass resignation acted as a window of opportunity, linking the lack of nursing staff (problem) to operational and structural changes (alternative solutions).

Transforming expertise from individual to regional community expertise: a four‐year study of an education intervention

In this paper we present the empirical results of a study showing that individualised expertise can be transformed into regional community expertise by means of an education intervention programme. In view of the ongoing reform of the municipal and service structures in Finland, during which small municipalities are combined into areas with populations in excess of 20,000, the need for community expertise is obvious. The reorganisation of service arrangements aims at efficiency, lower costs, quality service and increased regional competitiveness. Due to the reform, local actors are expected to provide new, collaboration‐oriented strategies, while healthcare professionals in the municipalities are presented with new challenges such as how to organise activities on a regional basis, form networks and work together in teams. An intervention study based on working life and with an emphasis on education was conducted using participatory action research between 1999 and 2003. The prerequisite of regional expertise is that individualised expertise evolves along with community expertise. An education intervention targeting entire work communities enables a change process in individual competence towards activity in communities and regions. Consequently, individualised expertise was highlighted by joint planning, work development and various evaluation skills. The change was supported by joint motivation for development, responsible commitment, adequate autonomy of the community, and by management practices and organisational structures that supported organisational changes. The delaying factors included workers' weak commitment, difficulty of giving up one's own specific expertise, a lack of common language and different subcultures. Our results indicate that work organisations can be developed through education so that workers jointly participate in changing the activities and work practices. This process will improve motivation and readiness for work as well as increase collaboration and efficiency of activity.
