    Tausta: VÀestön fyysisen aktiivisuuden ja liikunnan vÀhÀisyys aiheuttaa haasteita suomalaiselle yhteiskunnalle. Liikkumaton elÀmÀntapa lisÀÀ monia kansansairauksia ja kansantalouden kustannuksia ja on yhteydessÀ vÀestöryhmien vÀlisiin terveys- ja hyvinvointieroihin. Neurologista sairautta sairastaville kuntoutujille arjen fyysinen aktiivisuus ja liikunnan harrastaminen saattaa olla ongelmallista. Kun fyysisen aktiivisuuden ja liikunnan toteuttamisen edellytykset ovat kunnossa, edistetÀÀn terveyttÀ ja hyvinvointia, vÀhennetÀÀn eriarvoisuutta sekÀ tuetaan ihmisten vastuuta omasta terveydentilasta ja elÀmÀntavoista. Tutkimuksessa Liikunta kuntoutuksen tukena selvitettiin Kelan vaativan lÀÀkinnÀllisen kuntoutuksen fysioterapiaa saavien kuntoutujien liikunnan harrastamista edistÀviÀ ja rajoittavia tekijöitÀ sekÀ Kelan avoterapiastandardin sisÀltÀmÀÀ liikuntakokeilumahdollisuuden kÀyttöÀ. MenetelmÀt: Tutkimuksen kohderyhmÀnÀ olivat Kelan vaativan lÀÀkinnÀllisen kuntoutuksen fysioterapiaa saavat neurologista sairautta sairastavat suomen- ja ruotsinkieliset kuntoutujat Varsinais-Suomen alueella (N = 564), Kelan jÀrjestÀmÀn fysioterapian palveluntuottajat, joilla on vaikeavammaisia neurologisia kuntoutujia (Loimaa, Paimio, Turku ja Uusikaupunki) (n = 59) sekÀ nÀiden kuntien erityisliikunnasta vastaavat työntekijÀt (n = 4). Kuntoutujien aineisto poimittiin Kelan rekisteristÀ. Tutkimukseen vastasi 219 kuntoutujaa (38,8 %), 22 fysioterapeuttia (37,2 %) ja 2 kahden kunnan erityisliikunnasta vastaavaa työntekijÀÀ. Tutkimus toteutettiin kyselynÀ kuntoutujille sekÀ puhelinhaastatteluna ja sÀhköpostikyselynÀ fysioterapeuteille ja kunnan liikuntatoimen työntekijöille. Tulokset: Kyselyyn vastanneet kuntoutujat harrastivat eniten kÀvelyÀ tai juoksua, uintia tai vesijuoksua, luonnossa liikkumista ja kuntosaliharjoittelua. Luonnossa liikkumista, uintia tai vesijuoksua, kuntosaliharjoittelua ja tanssia sekÀ keilailua ja ratsastusta halusivat harrastaa myös ne kuntoutujat, jotka eivÀt aikaisemmin olleet harrastaneet nÀitÀ lajeja. Avoterapiastandardiin kuuluvaa liikuntakokeilumahdollisuutta oli hyödynnetty 58 vastaajan (26,7 %) fysioterapiassa. NykyistÀ liikunnan harrastamista kohtalaisesti edistivÀt vastaajan tietÀmys liikunnan ja terveyden vÀlisistÀ yhteyksistÀ sekÀ perheenjÀsenten asenteet ja rajoitti merkittÀvÀsti neurologinen oire. Liikunnan harrastamista lievÀsti edistÀvÀt oma motivaatio liikkua ja oma asenne, avustaja, asiantuntijoiden ohjaus, kuljetusjÀrjestelyt ja liikuntakaveri. LievÀsti nykyistÀ liikunnan harrastamista rajoittivat vastaajan liikunnalliset taidot sekÀ taloudellinen tilanne. Fysioterapeutit ja liikuntatoimi halusivat kehittÀÀ neurologista sairautta sairastavien kuntoutujien liikuntamahdollisuuksia ja toivoivat lisÀÀ tiedottamista kunnan liikuntapalveluista ja Kelan avoterapiastandardin kÀytöstÀ. JohtopÀÀtökset: Neurologista sairautta sairastavat kuntoutujat, fysioterapeutit ja kunnan erityisliikunnan työntekijÀt kannattivat avoterapiastandardin liikuntakokeilumahdollisuuden kÀyttöÀ, mikÀli liikuntatoiminnan edellytykset ovat kunnossa. Hyvin toteutettuna liikunta tukee kuntoutumista

    Validation of 3D echocardiographic volume detection of left atrium by human cadaveric casts

    Get PDF
    Background: Left atrial volume is a prognostic factor in cardiac pathologies. We aimed to validate left atrial volume detection with 3D and 2D echocardiography (3DE and 2DE) by human cadaveric casts. 3DE facilitates measurement of atrial volume without geometrical assumptions or dependence on imaging angle in contrast to 2DE methods. Methods: For method validation, six water-filled balloons were submerged in a 20-l water tank and their volumes were measured with 3DE. Seven human cadaveric left atrial casts were prepared of silicone and were transformed into ultrasound-permeable casts. Casts were imaged in the same setting, so that 3DE and 2DE of casts represented transthoracic apical view. Left ventricle analysis softwares GE 4D Auto LVQ and TomTec 4D LV-Function were used for 3DE volumetry. Results; Balloon volumes ranged 37 to 255ml (mean 126 ml). 3DE resulted in an excellent volumetric agreement with balloon volumes, absolute bias was -3.7 ml (95% CI -5.9 to -1.4). Atrial cast volumes were 38 to 94 ml (mean 56.6 ml). 3DE and 2DE volumes were excellently correlated with cast volumes (r = 0.96 to 0.99). Biases were for GE 4D LVQ - 0.7 ml (95% CI -6.1 to 4.6), TomTec 4D LV-Function 3.3 ml (-1.9 to 8.5) and 2DE 2.9 ml (-4.0 to 9.9). 3DE resulted in lower limits of agreement and showed no volume-related bias in contrast to area-length method. Conclusions: We conclude that measurement of human cadaveric left atrial cast volumes by 3DE is in excellent agreement with true cast volumes.Peer reviewe

    Nebular Line Emission During the Epoch of Reionization

    Full text link
    Nebular emission lines associated with galactic HII regions carry information about both physical properties of the ionised gas and the source of ionising photons as well as providing the opportunity of measuring accurate redshifts and thus distances once a cosmological model is assumed. While nebular line emission has been extensively studied at lower redshift there are currently only few constraints within the epoch of reionisation (EoR, z>6z>6), chiefly due to the lack of sensitive near-IR spectrographs. However, this will soon change with the arrival of the Webb Telescope providing sensitive near-IR spectroscopy covering the rest-frame UV and optical emission of galaxies in the EoR. In anticipation of Webb we combine the large cosmological hydrodynamical simulation Bluetides with photoionisation modelling to predict the nebular emission line properties of galaxies at z=8→13z=8\to 13. We find good agreement with the, albeit limited, existing direct and indirect observational constraints on equivalent widths though poorer agreement with luminosity function constraints.Comment: 17 pages, accepted to MNRAS, significant modification from v1.0 data available at https://stephenmwilkins.github.io/BluetidesEmissionLines_Public

    Counter Machines and Distributed Automata: A Story about Exchanging Space and Time

    Full text link
    We prove the equivalence of two classes of counter machines and one class of distributed automata. Our counter machines operate on finite words, which they read from left to right while incrementing or decrementing a fixed number of counters. The two classes differ in the extra features they offer: one allows to copy counter values, whereas the other allows to compute copyless sums of counters. Our distributed automata, on the other hand, operate on directed path graphs that represent words. All nodes of a path synchronously execute the same finite-state machine, whose state diagram must be acyclic except for self-loops, and each node receives as input the state of its direct predecessor. These devices form a subclass of linear-time one-way cellular automata.Comment: 15 pages (+ 13 pages of appendices), 5 figures; To appear in the proceedings of AUTOMATA 2018

    Mindsets and Failures : Neural Differences in Reactions to Mistakes among 2nd Grade Finnish Girls

    Get PDF
    Mindsets have been identified as an important factor in explaining learning differences among students. Growth mindset students have been shown to recover from mistakes easier than fixed mindset students, and recent neuroscientific research has shown differences in the brain’s event-related potentials to errors in fixed and growth mindset participants. The purpose of this study was to examine and evaluate these differences in the Finnish elementary school context. To achieve this, event-related potentials of five fixed and five growth mindset 8-9-year-old female students were recorded during a go/no-go task. Differences between the two groups emerged, however, they were different from the results of some previous studies in the field. These findings are discussed in the light of earlier neuroscientific research related to mindsets, including limitations and suggestions for future research in the field.Peer reviewe

    The ATF6-Met [67] Val substitution is associated with increased plasma cholesterol levels

    Get PDF
    Objective— Activating transcription factor 6 (ATF6) is a sensor of the endoplasmic reticulum stress response and regulates expression of several key lipogenic genes. We used a 2-stage design to investigate whether ATF6 polymorphisms are associated with lipids in subjects at increased risk for cardiovascular disease (CVD). Methods and Results— In stage 1, 13 tag-SNPs were tested for association in Dutch samples ascertained for familial combined hyperlipidemia (FCHL) or increased risk for CVD (CVR). In stage 2, we further investigated the SNP with the strongest association from stage 1, a Methionine/Valine substitution at amino-acid 67, in Finnish FCHL families and in subjects with CVR from METSIM, a Finnish population-based cohort. The combined analysis of both stages reached region-wide significance (P=9x10–4), but this association was not seen in the entire METSIM cohort. Our functional analysis demonstrated that Valine at position 67 augments ATF6 protein and its targets Grp78 and Grp94 as well as increases luciferase expression through Grp78 promoter. Conclusions— A common nonsynonymous variant in ATF6 increases ATF6 protein levels and is associated with cholesterol levels in subjects at increased risk for CVD, but this association was not seen in a population-based cohort. Further replication is needed to confirm the role of this variant in lipids. We report the association of the ATF6-methionine [67]valine amino-acid substitution with plasma cholesterol levels. Association analyses in 2674 subjects and functional data suggest that the ATF6 gene may influence cholesterol levels in subjects at increased risk to develop cardiovascular disease

    First Light And Reionisation Epoch Simulations (FLARES)  : IV. The size evolution of galaxies at z ≄ 5

    Get PDF
    We present the intrinsic and observed sizes of galaxies at z >= 5 in the First Light And Reionisation Epoch Simulations (flares). We employ the large effective volume of flares to produce a sizeable sample of high-redshift galaxies with intrinsic and observed luminosities and half-light radii in a range of rest-frame ultraviolet (UV) and visual photometric bands. This sample contains a significant number of intrinsically ultracompact galaxies in the far-UV (1500 angstrom), leading to a negative intrinsic far-UV size-luminosity relation. However, after the inclusion of the effects of dust these same compact galaxies exhibit observed sizes that are as much as 50 times larger than those measured from the intrinsic emission, and broadly agree with a range of observational samples. This increase in size is driven by the concentration of dust in the core of galaxies, heavily attenuating the intrinsically brightest regions. At fixed luminosity we find a galaxy size redshift evolution with a slope of m = 1.21-1.87 depending on the luminosity sample in question, and we demonstrate the wavelength dependence of the size-luminosity relation that will soon be probed by the James Webb Space Telescope.Peer reviewe

    Revisiting left atrial volumetry by magnetic resonance imaging : the role of atrial shape and 3D angle between left ventricular and left atrial axis

    Get PDF
    Background Accurate measurement of left atrial (LA) volumes is needed in cardiac diagnostics and the follow up of heart and valvular diseases. Geometrical assumptions with 2D methods for LA volume estimation contribute to volume misestimation. In this study, we test agreement of 3D and 2D methods of LA volume detection and explore contribution of 3D LA axis orientation and LA shape in introducing error in 2D methods by cardiovascular magnetic resonance imaging. Methods 30 patients with prior first-ever ischemic stroke and no known heart disease, and 30 healthy controls were enrolled (age 18-49) in a substudy of a prospective case-control study. All study subjects underwent cardiac magnetic resonance imaging and were pooled for this methodological study. LA volumes were calculated by biplane area-length method from both conventional long axis (LAV(AL-LV)) and LA long axis-oriented images (LAV(AL-LA)) and were compared to 3D segmented LA volume (LAV(SAX)) to assess accuracy of volume detection. 3D orientation of LA long axis to left ventricular (LV) long axis and to four-chamber plane were determined, and LA 3D sphericity indices were calculated to assess sources of error in LA volume calculation. Shapiro-Wilk test, Bland-Altman analysis, intraclass and Pearson correlation, and Spearman's rho were used for statistical analysis. Results Biases were - 9.9 mL (- 12.5 to - 7.2) for LAV(AL-LV) and 13.4 (10.0-16.9) for LAV(AL-LA) [mean difference to LAV(SAX) (95% confidence interval)]. End-diastolic LA long axis 3D deviation angle to LV long axis was 28.3 +/- 6.2 degrees [mean +/- SD] and LA long axis 3D rotation angle to four-chamber plane 20.5 +/- 18.0 degrees. 3D orientation of LA axis or 3D sphericity were not correlated to error in LA volume calculation. Conclusions Calculated LA volume accuracy did not improve by using LA long axis-oriented images for volume calculation in comparison to conventional method. We present novel data on LA axis orientation and a novel metric of LA sphericity and conclude that these measures cannot be utilized to assess error in LA volume calculation.Peer reviewe

    Can processes make relationships work? The Triple Helix between structure and action

    Get PDF
    This contribution seeks to explore how complex adaptive theory can be applied at the conceptual level to unpack Triple Helix models. We use two cases to examine this issue – the Finnish Strategic Centres for Science, Technology & Innovation (SHOKs) and the Canadian Business-led Networks of Centres of Excellence (BL-NCE). Both types of centres are organisational structures that aspire to be business-led, with a considerable portion of their activities driven by (industrial) users’ interests and requirements. Reflecting on the centres’ activities along three dimensions – knowledge generation, consensus building and innovation – we contend that conceptualising the Triple Helix from a process perspective will improve the dialogue between stakeholders and shareholders

    Cardiac Involvement in Fabry Disease: JACC Review Topic of the Week

    Get PDF
    Fabry disease (FD) is a rare X-linked inherited lysosomal storage disorder caused by deficient α-galactosidase A activity that leads to an accumulation of globotriasylceramide (Gb3) in affected tissues, including the heart. Cardiovascular involvement usually manifests as left ventricular hypertrophy, myocardial fibrosis, heart failure, and arrhythmias, which limit quality of life and represent the most common causes of death. Following the introduction of enzyme replacement therapy, early diagnosis and treatment have become essential to slow disease progression and prevent major cardiac complications. Recent advances in the understanding of FD pathophysiology suggest that in addition to Gb3 accumulation, other mechanisms contribute to the development of Fabry cardiomyopathy. Progress in imaging techniques have improved diagnosis and staging of FD-related cardiac disease, suggesting a central role for myocardial inflammation and setting the stage for further research. In addition, with the recent approval of oral chaperone therapy and new treatment developments, the FD-specific treatment landscape is rapidly evolving
