Species co-occurrence networks of ground beetles in managed grasslands
2020
AbstractGrassland biodiversity, including traditional rural biotopes maintained by traditional agricultural practices, has become threatened worldwide. Road verges have been suggested to be complementary or compensatory habitats for species inhabiting grasslands. Species co-occurrence patterns linked with species traits can be used to separate between the different mechanisms (stochasticity, environmental filtering, biotic interactions) behind community structure. Here, we study species co-occurrence networks and underlying mechanisms of ground beetle species (Carabidae) in three different managed grassland types (meadows, pastures, road verges, n = 12 in each type) in Central Finland. We a…
Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representat…
2021
Background: hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. Methods: we used data from 1990 to 2019 on people aged 30-79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prev…
Incidence and management of patients with colorectal cancer and synchronous and metachronous colorectal metastases : a population-based study
2020
Background This population‐based study aimed to examine the incidence, patterns and results of multimodal management of metastatic colorectal cancer. Methods A retrospective population‐based study was conducted on patients with metastatic colorectal cancer in Central Finland in 2000–2015. Clinical and histopathological data were retrieved and descriptive analysis was conducted to determine the pattern of metastatic disease, defined as synchronous, early metachronous (within 12 months of diagnosis of primary disease) and late metachronous (more than 12 months after diagnosis). Subgroups were compared for resection and overall survival (OS) rates. Results Of 1671 patients, 296 (17·7 per cent)…
Occurrence and recovery potential of rare earth elements in Finnish peat and biomass combustion fly ash
2019
Rare earth elements (REEs) are highly important in the modern society as a result of their wide use in various fields of industry. Their high supply risk and increase in demand has led to classification as critical materials, and consequently, new resources for REEs are being prospected widely. Coal fly ash has been suggested as a possible secondary resource for REEs, but very little information is available regarding REE occurrence in biomass or peat derived fly ash. In this paper, fly ash samples from commercial power plants using peat and biomass as fuel were studied for REEs. The average concentration of REEs was 530 ppm, with up to 920 ppm in one fly ash. Five out of seven fly ashes we…
Effect of Land-Use Change on the Changes in Human Lyme Risk in the United States
2022
The spatial extent and incidence of Lyme disease is increasing in the United States, particularly in the Upper Midwest and Northeast. Many previous studies have explored the drivers of its spatial pattern, however, few studies tried to explore the drivers for the changes of Lyme disease. We here compared the spatial patterns of changes of human Lyme cases and incidence in the Northeast and Upper Midwest between 2003–2005 and 2015–2017, and applied two different approaches (i.e., a statistical regularization approach and model averaging) to investigate the climatic and landscape factors affecting the risk change between the two periods. Our results suggested that changes in land-use variable…
Sarkopenian esiintyvyys ja vaikeusaste 70–85-vuotiailla henkilöillä (PASSWORD-tutkimus)
2022
Sarkopenia on ikääntymiseen liittyvä sairaus, joka johtaa lihaskatoon ja lihasvoiman heikkenemiseen ja on yksi tärkeimmistä terveysongelmista ikääntyneillä ihmisillä. Tämän tutkimuksen tarkoituksena oli selvittää sarkopenian esiintyvyyttä jyväskyläläisten iäkkäiden kotona asuvien väestössä. Sarkopenian esiintyvyyden arvioimiseksi henkilöt luokiteltiin lihasvoiman ollessa normaali ei sarkopenia ryhmään (ES), alentuneen lihasvoiman perusteella mahdollinen sarkopenia ryhmään (MS) ja alentuneen lihasvoiman sekä lihasmassan perusteella sarkopenia ryhmään (SR). Lisäksi ryhmien välisiä eroja tarkasteltiin iässä, kehonkoostumuksessa, toimintakyvyssä ja objektiivisesti mitatussa fyysisessä aktiivisu…
Luku- ja laskusujuvuuden vaikeuksien yhteisesiintyvyys ja pysyvyys alakouluikäisillä oppilailla
2017
Tämän tutkielman tarkoituksena on selvittää luku- ja laskusujuvuuden vaikeuksien päällekkäistymisen eli komorbiditeetin esiintyvyyttä ja toisaalta sen pysyvyyttä alakouluikäisillä oppilailla. Käyttämämme aineisto on osa Minäpystyvyys ja oppimisvaikeusinterventiot (SELDI) -hanketta, johon osallistui 1385 2.–5. luokan oppilasta keski- ja itäsuomalaisista kunnista. Luku- ja laskusujuvuuden mittareina käytettiin aikarajallisia testejä, jotka toteutettiin ryhmätestauksena. Esiintyvyyttä ja pysyvyyttä analysoitiin tilastollisin menetelmin käyttämällä 7. ja 16. persentiilin katkaisurajoja. Pysyvyyttä tarkasteltiin vuoden seurantajakson aikana. Tulosten perusteella 28–43 %:lla oppilaista, joilla ol…
Comparing the Climatic and Landscape Risk Factors for Lyme Disease Cases in the Upper Midwest and Northeast United States
2020
Lyme disease, recognized as one of the most important vector-borne diseases worldwide, has been increasing in incidence and spatial extend in United States. In the Northeast and Upper Midwest, Lyme disease is transmitted by Ixodes scapularis. Currently, many studies have been conducted to identify factors influencing Lyme disease risk in the Northeast, however, relatively few studies focused on the Upper Midwest. In this study, we explored and compared the climatic and landscape factors that shape the spatial patterns of human Lyme cases in these two regions, using the generalized linear mixed models. Our results showed that climatic variables generally had opposite correlations with Lyme d…
Myopia - maailmanlaajuinen epidemia
2021
• Myopian eli likinäköisyyden esiintyvyys on viime vuosikymmeninä lisääntynyt voimakkaasti. • Tähän ovat ilmeisesti vaikuttaneet voimakkaimmin lähikatselun lisääntyminen ja ulkona vietetyn ajan väheneminen. Perintötekijät selittävät myopiasta vain pienen osan. • Ulkoilun lisäämisellä ja pitkäkestoisen lähikatselun välttämisellä on voitu vähentää lasten myopian ilmaantuvuutta. • Useiden silmäsairauksien ja näkövammaisuuden riski lisääntyy myopian voimistuessa. • Atropiinisilmätippojen käytöstä on raportoitu olevan hyötyä likinäköisyyden etenemisen hidastamisessa, mutta pidempiaikaisista hyödyistä ja mahdollisista haitoista tarvitaan seurantatietoa. The prevalence of myopia has increased sig…
The impact of wildlife and environmental factors on hantavirus infection in the host and its translation into human risk
2023
Identifying factors that drive infection dynamics in reservoir host populations is essential in understanding human risk from wildlife-originated zoonoses. We studied zoonotic Puumala orthohantavirus (PUUV) in the host, the bank vole ( Myodes glareolus ), populations in relation to the host population, rodent and predator community and environment-related factors and whether these processes are translated into human infection incidence. We used 5-year rodent trapping and bank vole PUUV serology data collected from 30 sites located in 24 municipalities in Finland. We found that PUUV seroprevalence in the host was negatively associated with the abundance of red foxes, but this process did no…
