Critical elements underpinning the emergence of the medical game ecosystem:gamifying traumatic brain injury rehabilitation in Finland

The healthcare sector is currently in the verge of a reform and thus, the medical game research provide an interesting area of research. The aim of this study is to explore the critical elements underpinning the emergence of the medical game ecosystem with three sub-objectives: (1) to seek who are the key actors involved in the medical game ecosystem and identify their needs, (2) to scrutinise what types of resources are required in medical game development and what types of relationships are needed to secure those resources, and (3) to identify the existing institutions (‘the rules of the game’) affecting the emergence of the medical game ecosystem. The theoretical background consists of service ecosystems literature. The empirical study conducted is based on the semi-structured theme interviews of 25 experts in three relevant fields: games and technology, health and funding. The data was analysed through a theoretical framework that was designed based upon service ecosystems literature. The study proposes that the key actors are divided into five groups: medical game companies, customers, funders, regulatory parties and complementors. Their needs are linked to improving patient motivation and enhancing the healthcare processes resulting in lower costs. Several types of resources, especially skills and knowledge, are required to create a medical game. To gain access to those resources, medical game companies need to build complex networks of relationships. Proficiency in managing those value networks is crucial. In addition, the company should take into account the underlying institutions in the healthcare sector affecting the medical game ecosystem. Three crucial institutions were identified: validation, lack of innovation supporting structures in healthcare and the rising consumerisation. Based on the findings, medical games cannot be made in isolation. A developmental trajectory model of the emerging medical game ecosystem was created based on the empirical data. The relevancy of relationships and resources is dependent on the trajectory that the medical game company at that time resides. Furthermore, creating an official and documented database for clinically validated medical games was proposed to establish the medical game market and ensure an adequate status for the effective medical games. Finally, ecosystems approach provides interesting future opportunities for research on medical game ecosystems

Prediction of neurodevelopment and neuromotor trajectories in very preterm born children up to 11 years of age: PIPARI Study

Very preterm birth is a risk for brain injury and abnormal neurodevelopment. While the incidence of cerebral palsy has decreased due to advances in perinatal and neonatal care, the rate of less severe neuromotor problems continues to be high in very prematurely born children. Neonatal brain imaging can aid in identifying children for closer follow-up and in providing parents information on developmental risks. This thesis aimed to study the predictive value of structural brain magnetic resonance imaging (MRI) at term age, serial neonatal cranial ultrasound (cUS), and structured neurological examinations during the longitudinal follow-up for the neurodevelopment of very preterm born children up to 11 years of age as a part of the PIPARI Study (The Development and Functioning of Very Low Birth Weight Infants from Infancy to School Age). A further aim was to describe the associations between regional brain volumes and long-term neuromotor profile. The prospective follow-up comprised of the assessment of neurosensory development at 2 years of corrected age, cognitive development at 5 years of chronological age, and neuromotor development at 11 years of age. Neonatal brain imaging and structured neurological examinations predicted neurodevelopment at all age-points. The combination of neurological examination and brain MRI or cUS improved the predictive value of neonatal brain imaging alone. Decreased brain volumes associated with neuromotor performance. At the age of 11 years, the majority of the very preterm born children had age-appropriate neuromotor development and after-school sporting activities. Long-term clinical follow-up is recommended at least for all very preterm infants with major brain pathologies.

Terveysneuvontaan osallistuneiden 70-vuotiaiden elämän- laadun muutos vuoden seuranta-aikana

Tutkimuksen tarkoituksena oli kuvata erään suomalaisen kunnan 70-vuotiaiden ikäkohortin koettua elämänlaatua, terveystottumuksia ja toimintakykyä sekä selvittää terveysneuvontaan osallistuneiden 70-vuotiaiden elämänlaadun, terveystottumusten ja toimintakyvyn muutosta vuoden seuranta-aikana. Lisäksi tutkimuksen tarkoituksena oli selvittää terveystottumusten ja toimintakyvyn muutosten yhteyttä elämänlaadun muutokseen. Tutkimuksen aineisto kerättiin erään suomalaisen kunnan alueen 70 vuotta täyttäneiltä, itsenäisesti kotona asuvilta ikäneuvolapalvelun käyttäjiltä. Aineisto kerättiin ikäneuvolakäynnin yhteydessä kyselylomakkeella, jonka keskeiset kohteet olivat 1) elämänlaatu 2) terveystottumukset ja 3) toimintakyky. Kyselylomakkeen elämänlaatua arvioiva osa muodostui Maailman terveysjärjestö WHO:n elämänlaatumittarista WHOQOL-BREF. Tutkimuksen otos muodostui kolmen vuoden ikäkohortista, johon kuului vuosien 2010, 2011 ja 2012 aikana 70 vuotta täyttäneet kuntalaiset (N=365). Seurantakysely samalla kyselylomakkeella toteutettiin vuoden kuluttua ikäneuvolakäynnistä. Ensimmäisen kyselylomakkeen täytti 297 henkilöä (aineisto n1) ja toisen seurantalomakkeen täytti 224 henkilöä (aineisto n2). Aineisto analysoitiin IBM SPSS Statistics 23.0 -tilasto-ohjelmalla. 70-vuotiaat kokivat yleisen elämänlaatunsa pääasiassa hyväksi tai erittäin hyväksi. Enemmistö oli melko tyytyväinen terveyteensä, koki liikuntakykynsä hyväksi, ja suoriutui hyvin päivittäisistä toiminnoista. Terveystottumuksia tarkasteltaessa terveysneuvontaan osallistuneet 70-vuotiaat liikkuivat säännöllisesti, enemmistö 70-vuotiaista ei tupakoinut, ja alkoholitottumukset olivat kohtuullisella tasolla. 70-vuotiaiden koettu elämänlaatu on WHO:n elämänlaadun ulottuvuuksilla mitattuna korkea, mutta sosiaalinen ulottuvuus koettiin suomalaista ikäryhmää heikommaksi erityisesti miesten keskuudessa. Millään elämänlaadun ulottuvuudella ei tapahtunut muutosta vuoden seuranta-aikana. Heikon elämänlaadun riskiryhmään kuuluvien, terveysneuvontaan osallistuneiden 70-vuotiaiden elämänlaatu oli kohentunut elämänlaadun eri osa-alueilla vuoden seuranta-aikana. Yksinäisyyden tunne oli vähentynyt, tyytyväisyys kykyyn selviytyä päivittäisistä toimista sekä tyytyväisyys terveyteen olivat parantuneet tilastollisesti merkitsevästi. 70-vuotiaiden koettu elämänlaatu, terveystottumukset ja toimintakyky ovat yleisesti hyvällä tasolla. Terveysneuvonta voi edistää itsenäistä kotona asumista elämänlaatua tukevilla keinoilla. Erityisesti riskiryhmät näyttävät hyötyvän terveysneuvonnasta. Tutkimustuloksia voidaan hyödyntää räätälöityjen terveydenhuollon palvelujen kehittämisessä. Tutkimus toimii pohjana jatkotutkimukselle, jonka tavoitteena on kehittää uusia strategioita itsenäiseen kotona asumiseen.

Promoting Healthy Lifestyles with Personalized, APOE Genotype Based Health Information: The Effects on Psychological-, Health Behavioral and Clinical Factors

There is an increasing demand for individualized, genotype-based health advice. The general population-based dietary recommendations do not always motivate people to change their life-style, and partly following this, cardiovascular diseases (CVD) are a major cause of death in worldwide. Using genotype-based nutrition and health information (e.g. nutrigenetics) in health education is a relatively new approach, although genetic variation is known to cause individual differences in response to dietary factors. Response to changes in dietary fat quality varies, for example, among different APOE genotypes. Research in this field is challenging, because several non-modifiable (genetic, age, sex) and modifiable (e.g. lifestyle, dietary, physical activity) factors together and with interaction affect the risk of life-style related diseases (e.g. CVD). The other challenge is the psychological factors (e.g. anxiety, threat, stress, motivation, attitude), which also have an effect on health behavior. The genotype-based information is always a very sensitive topic, because it can also cause some negative consequences and feelings (e.g. depression, increased anxiety). The aim of this series of studies was firstly to study how individual, genotype-based health information affects an individual’s health form three aspects, and secondly whether this could be one method in the future to prevent lifestyle-related diseases, such as CVD. The first study concentrated on the psychological effects; the focus of the second study was on health behavior effects, and the third study concentrated on clinical effects. In the fourth study of this series, the focus was on all these three aspects and their associations with each other. The genetic risk and health information was the APOE gene and its effects on CVD. To study the effect of APOE genotype-based health information in prevention of CVD, a total of 151 volunteers attended the baseline assessments (T0), of which 122 healthy adults (aged 20 – 67 y) passed the inclusion criteria and started the one-year intervention. The participants (n = 122) were randomized into a control group (n = 61) and an intervention group (n = 61). There were 21 participants in the intervention Ɛ4+ group (including APOE genotypes 3/4 and 4/4) and 40 participants in the intervention Ɛ4- group (including APOE genotypes 2/3 and 3/3). The control group included 61 participants (including APOE genotypes 3/4, 4/4, 2/3, 3/3 and 2/2). The baseline (T0) and follow-up assessments (T1, T2, T3) included detailed measurements of psychological (threat and anxiety experience, stage of change), and behavioral (dietary fat quality, consumption of vegetables, - high fat/sugar foods and –alcohol, physical activity and health and taste attitudes) and clinical factors (total-, LDL- HDL cholesterol, triglycerides, blood pressure, blood glucose (0h and 2h), body mass index, waist circumference and body fat percentage). During the intervention six different communication sessions (lectures on healthy lifestyle and nutrigenomics, health messages by mail, and personal discussion with the doctor) were arranged. The intervention groups (Ɛ4+ and Ɛ4-) received their APOE genotype information and health message at the beginning of the intervention. The control group received their APOE genotype information after the intervention. For the analyses in this dissertation, the results for 106/107 participants were analyzed. In the intervention, there were 16 participants in the high-risk (Ɛ4+) group and 35 in the low-risk (Ɛ4-) group. The control group had 55 participants in studies III-IV and 56 participants in studies I-II. The intervention had both short-term (≤ 6 months) and long-term (12 months) effects on health behavior and clinical factors. The short-term effects were found in dietary fat quality and waist circumference. Dietary fat quality improved more in the Ɛ4+ group than the Ɛ4- and the control groups as the personal, genotype-based health information and waist circumference lowered more in the Ɛ4+ group compared with the control group. Both these changes differed significantly between the Ɛ4+ and control groups (p<0.05). A long-term effect was found in triglyceride values (p<0.05), which lowered more in Ɛ4+ compared with the control group during the intervention. Short-term effects were also found in the threat experience, which increased mostly in the Ɛ4+ group after the genetic feedback (p<0.05), but it decreased after 12 months, although remaining at a higher level compared to the baseline (T0). In addition, Study IV found that changes in the psychological factors (anxiety and threat experience, motivation), health and taste attitudes, and health behaviors (dietary, alcohol consumption, and physical activity) did not directly explain the changes in triglyceride values and waist circumference. However, change caused by a threat experience may have affected the change in triglycerides through total- and HDL cholesterol. In conclusion, this dissertation study has given some indications that individual, genotypebased health information could be one potential option in the future to prevent lifestyle-related diseases in public health care. The results of this study imply that personal genetic information, based on APOE, may have positive effects on dietary fat quality and some cardiovascular risk markers (e.g., improvement in triglyceride values and waist circumference). This study also suggests that psychological factors (e.g. anxiety and threat experience) may not be an obstacle for healthy people to use genotype-based health information to promote healthy lifestyles. However, even in the case of very personal health information, in order to achieve a permanent health behavior change, it is important to include attitudes and other psychological factors (e.g. motivation), as well as intensive repetition and a longer intervention duration. This research will serve as a basis for future studies and its information can be used to develop targeted interventions, including health information based on genotyping that would aim at preventing lifestyle diseases. People’s interest in personalized health advices has increased, while also the costs of genetic screening have decreased. Therefore, generally speaking, it can be assumed that genetic screening as a part of the prevention of lifestyle-related diseases may become more common in the future. In consequence, more research is required about how to make genetic screening a practical tool in public health care, and how to efficiently achieve long-term changes.

Cholesterol, cardiovascular disease and statin use in older persons

Older age increases the risk of developing a chronic atherosclerotic cardiovascular disease (CVD), such as coronary heart disease. Complications of CVDs, myocardial infarction or stroke often lead to loss of functional capacity or premature death. Dyslipidemia, high serum levels of total or low-density lipoprotein cholesterol (LDL-c) and low levels of high-density lipoprotein cholesterol (HDL-c), is among the most important modifiable risk factors for CVDs; it can be treated with lifestyle modifications, and with lipid-lowering drugs, primarily statins. In older persons, however, the association of cholesterol levels with cardiovascular and all-cause mortality has been inconsistent in previous studies. Furthermore, the beneficial effects of statins in older persons without previous CVD are still somewhat unclear, and older persons are more prone to adverse effects from statins. This thesis presents a prospective cohort study (TUVA), exploring associations of cholesterol levels with mortality and the changes in cholesterol levels of a 70-year-old population in long-term follow-up. Further, prevalence of CVDs, risk factors and preventive medication use in the TUVA cohort is compared with respective prevalences in another age-matched cohort (UTUVA) 20 years later in order to examine the changes in cardiovascular risk over time. Additionally, to evaluate statin use patterns among older persons, an observational register study was conducted covering the total Finnish population aged 70 and older during 2000-2008. Based on individual-level data retrieved from national health registries, the population was classified into low, moderate and high risk groups according to estimated CVD risk. The prevalence, incidence and persistence of statin use among the risk groups was then evaluated based upon yearly statin purchases tracked from the Prescription Register. The prospective cohort study demonstrated that low total cholesterol, LDL-c and HDL-c were associated with higher mortality in a cohort of home-dwelling 70-year-olds. However, after adjusting for traditional cardiovascular risk factors and cancer this association disappeared. Further, low total cholesterol seemed to be protective, whereas low HDL-c strongly predicted increased risk of CVD death. Cholesterol levels of those elderly who remained available for follow-up and were still home-dwelling at the age of 85 seemed to improve with advancing age. Compared to the TUVA cohort, the later born UTUVA cohort had less CVDs and their risk factors were better controlled, which was reflected in the higher use of preventive medications such as statins and antihypertensives. The register studies confirmed that statin use has increased significantly during 2000-2008 among older persons, especially among the oldest (80+) age groups and among those at high risk for cardiovascular events. Two-thirds of new statin users persisted with their use during the four years of follow-up; the most discontinuations were made during the first year of use. In conclusion, statins are commonly used among older age groups in Finland. Most of the older statin users had a high cardiovascular event risk, indicating that the treatment is well directed towards those who are likely to benefit from it the most. No age-limits should be put on the screening and treatment of dyslipidemia in older persons, but the benefits and adverse effects of statin treatment should be carefully weighed based on an individual assessment of the person’s general health status and functional capacity. Physicians should pay more attention to medication adherence, especially when prescribing preventive medications.

Kontulan vanhustenkeskuksen päivätoimintayksikön asiakkaiden fyysinen toimintakyky ja fyysinen toimintaympäristö

Opinnäytetyömme on osa IKU-hanketta, joka on Helsingin ammattikorkeakoulu Stadian ja Teknillisen korkeakoulun Sotera-instituutin yhteisprojekti. IKU-hanke on ikäihmisten kuntoutumista tukevien toimintaympäristöjen kehittämiseksi käynnistetty hanke. Opinnäytetyömme tarkoituksena oli selvittää millainen on Kontulan vanhustenkeskuksen päivätoimintayksikkö Päivikin asiakkaiden fyysinen toimintakyky TOIMIVA-testistöllä mitattuna. Lisäksi selvitimme työssämme millainen on Päivikin fyysinen toimintaympäristö tarkasteluna TOIMIVA-testistön osa-alueiden kautta. TOIMIVA-testistö on iäkkään ihmisen toimintakykyä arvioiva mittari. Mittasimme Päivikin asiakkaiden fyysistä toimintakykyä TOIMIVA-testistöllä Kontulan vanhustenkeskuksen tiloissa 28.5 - 1.6.2007. Kohdejoukkoomme kuului yhteensä 32 asiakasta, joista 20 oli naisia ja 12 miehiä. Kohdejoukon ikäjakauma oli 63-96 vuotta. Lisäksi tarkastelimme kahtena erillisenä päivänä Päivikin fyysistä toimintaympäristöä sekä havainnoimme asiakkaiden toimimista siinä. Kontulan vanhustenkeskuksen on tarkoitus muuttaa uusiin tiloihin noin kahden vuoden kuluttua. TOIMIVA-testistön tulosten perusteella pystyimme päättelemään, että Päivikin asiakkaiden alaraajojen lihasvoima ja tasapaino ovat useimmilla asiakkailla heikompia kuin TOIMIVA-testistön vertailuarvot. Ympäristöä havainnoidessamme tulimme siihen tulokseen, että ympäristö on suunniteltu ikääntyneitä varten ja, että ympäristössä on helppo liikkua apuvälineiden avulla. Asiakkailla on mahdollisuus ylläpitää ja kehittää fyysistä toimintakykyä Päivikin ympäristössä, mutta asiakkaat eivät välttämättä ole tietoisia ympäristön erilaisista hyödyntämismahdollisuuksista fyysisen toimintakyvyn ylläpitämisessä ja kehittämisessä. Lisäksi asiakkaille olisi hyvä tarjota enemmän mahdollisuuksia osallistua Päivikin arkisten asioiden hoitamiseen ja näin ylläpitää ja kehittää fyysistä toimintakykyään. Opinnäytetyömme on kartoittava tutkimus, jonka tuloksia ei voida yleistää, koska kohdejoukko on pieni ja otos harkinnanvarainen. Opinnäytetyömme antaa Päivikin työntekijöille tietoa asiakkaidensa toimintakyvystä. Kontulan vanhustenkeskus voi käyttää opinnäytetyössämme esitettyä tietoa hyödyksi suunnitellessaan Päivikin uutta toimintatilaa. Lisäksi ikääntyneiden kanssa työskentelevä henkilökunta voi hyötyä omassa työssään opinnäytetyöhömme kerätystä tiedosta.
