From a "Student" to a Lifelong "Consumer" : Constructions of Educability in Adult Students' Narrative Life Histories

The focus of this study was to examine the constructions of the educable subject of the lifelong learning (LLL) narrative in the narrative life histories of adult students at general upper secondary school for adults (GUSSA). In this study lifelong learning has been defined as a cultural narrative on education, “a system of political thinking” that is not internally consistent, but has contradictory themes embedded within it (Billig et al., 1988). As earlier research has shown and this study also confirms, the LLL narrative creates differences between those who are included and those who fall behind and are excluded from the learning society ideal. Educability expresses socially constructed interpretations on who benefit from education and who should be educated and how. The presupposition in this study has been that contradictions between the LLL narrative and the so-called traditional constructions of educability are likely to be constructed as the former relies on the all-inclusive interpretation of educability and the latter on the meritocratic model of educating individuals based on their innate abilities. The school system continues to uphold the institutionalized ethos of educability that ranks students into the categories “bright”, “mediocre”, and “poor” (Räty & Snellman, 1998) on the basis of their abilities, including gender-related differences as well as differences based on social class. Traditional age-related norms also persist, for example general upper secondary education is normatively completed in youth and not in adulthood, and the formal learning context continues to outweigh both non-formal and informal learning. Moreover, in this study the construction of social differences in relation to educability and, thereafter unequal access to education has been examined in relation to age, social class, and gender. The biographical work of the research participants forms a peephole that permits the examination of the dilemmatic nature of the constructions of educability in this study. Formal general upper secondary education in adulthood is situated on the border between the traditional and the LLL narratives on educability: participation in GUSSA inevitably means that one’s ability and competence as a student and learner becomes reassessed through the assessment criteria maintained by schools, whereas according to the principles of LLL everyone is educable; everyone is encouraged to learn throughout their lives regardless of age, social class, or gender. This study is situated in the field of adult education, sociology of education, and social psychological research on educability, having also been informed by feminist studies. Moreover, this study contributes to narrative life history research combining the structural analysis of narratives (Labov & Waletzky, 1997), i.e. mini-stories within life history, with the analysis of the life histories as structural and thematic wholes and the creation of coherence in them; thus, permitting both micro and macro analyses. On accounting for the discontinuity created by participation in general upper secondary school study in adulthood and not normatively in youth, the GUSSA students construct coherence in relation to their ability and competence as students and learners. The seven case studies illuminate the social differences constructed in relation to educability, i.e. social class, gender, age, and the “new category of student and learner”. In the data of this study, i.e. 20 general upper secondary school adult graduates’ narrative life histories primarily generated through interviews, two main coherence patterns of the adult educable subject emerge. The first performance-oriented pattern displays qualities that are closely related to the principles of LLL. Contrary to the principles of lifewide learning, however, the documentation of one’s competence through formal qualifications outweighs non-formal and informal learning in preparation for future change and the competition for further education, professional careers, and higher social positions. The second flexible learning pattern calls into question the status of formal, especially theoretical and academically oriented education; inner development is seen as more important than such external signs of development — grades and certificates. Studying and learning is constructed as a hobby and as a means to a more satisfactory life as opposed to a socially and culturally valued serious occupation leading to further education and career development. Consequently, as a curious, active, and independent learner, this educable but not readily employable subject is pushed into the periphery of lifelong learning. These two coherence patterns of the adult educable subject illuminate who is to be educated and how. The educable and readily employable LLL subject is to participate in formal education in order to achieve qualifications for working life, whereas the educable but not employable subject may utilize lifewide learning for her/his own pleasure. Key words: adult education, general upper secondary school for adults, educability, lifelong learning, narrative life history

Living arrangements and health

In line with major demographic changes in other Northern European and North American countries and Australia, being nonmarried is becoming increasingly common in Finland, and the proportion of cohabiters and of persons living alone has grown in recent decades. Official marital status no longer reflects an individual s living arrangement, as single, divorced and widowed persons may live alone, with a partner, with children, with parents, with siblings, or with unrelated persons. Thus, more than official marital status, living arrangements may be a stronger discriminator of one s social bonds and health. The general purpose of this study was to deepen our current understanding of the magnitude, trends, and determinants of ill health by living arrangements in the Finnish working-age population. Distinct measures of different dimensions of poor health, as well as an array of associated factors, provided a comprehensive picture of health differences by living arrangements and helped to assess the role of other factors in the interpretation of these differences . Mortality analyses were based on Finnish census records at the end of 1995 linked with cause-of-death registers for 1996 2000. The data included all persons aged 30 and over. Morbidity analyses were based on two comparable cross-sectional studies conducted twenty years apart (the Mini-Finland Survey in 1978 80 and the Health 2000 Survey in 2000 01). Both surveys were based on nationally representative samples of Finns aged 30 and over, and benefited from high participation rates. With the exception of mortality analyses, this study focused on health differences among the working-age population (mortality in age groups 30-64 and 65 and over, self-rated health and mental health in the age group 30-64, and unhealthy alcohol use in the age group 30-54). Compared with all nonmarried groups, married men and women exhibited the best health in terms of mortality, self-rated health, mental health and unhealthy alcohol use. Cohabiters did not differ from married persons in terms of self-rated health or mental health, but did exhibit excess unhealthy alcohol use and high mortality, particularly from alcohol-related causes. Compared with the married, persons living alone or with someone other than a partner exhibited elevated mortality as well as excess poor mental health and unhealthy alcohol use. By all measures of health, men and women living alone tended to be in the worst position. Over the past twenty years, SRH had improved least among single men and women and widowed women, and most among cohabiting women. The association between living arrangements and health has many possible explanations. The health-related selection theory suggests that healthy people are more likely to enter and maintain a marriage or a consensual union than those who are unhealthy (direct selection) or that a variety of health-damaging behavioural and social factors increase the likelihood of ill health and the probability of remaining without a partner or becoming separated from one s partner (indirect selection). According to the social causation theory, marriage or cohabitation has a health-promoting effect, whereas living alone or with others than a partner has a detrimental effect on health. In this study, the role of other factors that are mainly assumed to reflect selection, appeared to be rather modest. Social support, which reflects social causation, contributed only modestly to differences in unhealthy alcohol use by living arrangements, but had a larger effect on differences in poor mental health. Socioeconomic factors and health-related behaviour, which reflect both selection and causation, appeared to play a more important role in the excess poor health of cohabiters and of persons living alone or with someone other than a partner, than of married persons. Living arrangements were strongly connected to various dimensions of ill health. In particular, alcohol consumption appeared to be of great importance in the association between living arrangements and health. To the extent that the proportion of nonmarried persons continues to grow and their health does not improve at the same rate as that of married persons, the challenges that currently nonmarried persons pose to public health will likely increase.

Perspectives on prescribing in nursing homes in Helsinki

Prescribing for older patients is challenging. The prevalence of diseases increases with advancing age and causes extensive drug use. Impairments in cognitive, sensory, social and physical functioning, multimorbidity and comorbidities, as well as age-related changes in pharmacokinetics and pharmacodynamics all add to the complexity of prescribing. This study is a cross-sectional assessment of all long-term residents aged ≥ 65 years in all nursing homes in Helsinki, Finland. The residents’ health status was assessed and data on their demographic factors, health and medications were collected from their medical records in February 2003. This study assesses some essential issues in prescribing for older people: psychotropic drugs (Paper I), laxatives (Paper II), vitamin D and calcium supplements (Paper III), potentially inappropriate drugs for older adults (PIDs) and drug-drug interactions (DDIs)(Paper IV), as well as prescribing in public and private nursing homes. A resident was classified as a medication user if his or her medication record indicated a regular sequence for its dosage. Others were classified as non-users. Mini Nutritional Assessment (MNA) was used to assess residents’ nutritional status, Beers 2003 criteria to assess the use of PIDs, and the Swedish, Finnish, INteraction X-referencing database (SFINX) to evaluate their exposure to DDIs. Of all nursing home residents in Helsinki, 82% (n=1987) participated in studies I, II, and IV and 87% (n=2114) participated in the study III. The residents’ mean age was 84 years, 81% were female, and 70% were diagnosed with dementia. The mean number of drugs was 7.9 per resident; 40% of the residents used ≥ 9 drugs per day, and were thus exposed to polypharmacy. Eighty percent of the residents received psychotropics; 43% received antipsychotics, and 45% used antidepressants. Anxiolytics were prescribed to 26%, and hypnotics to 28% of the residents. Of those residents diagnosed with dementia, 11% received antidementia drugs. Fifty five percent of the residents used laxatives regularly. In multivariate analysis, those factors associated with regular laxative use were advanced age, immobility, poor nutritional status, chewing problems, Parkinson’s disease, and a high number of drugs. Eating snacks between meals was associated with lower risk for laxative use. Of all participants, 33% received vitamin D supplementation, 28% received calcium supplementation, and 20% received both vitamin D and calcium. The dosage of vitamin D was rather low: 21% received vitamin D 400 IU (10 µg) or more, and only 4% received 800 IU (20 µg) or more. In multivariate analysis, residents who received vitamin D supplementation enjoyed better nutritional status, ate snacks between meals, suffered no constipation, and received regular weight monitoring. Those residents receiving PIDs (34% of all residents) more often used psychotropic medication and were more often exposed to polypharmacy than residents receiving no PIDs. Residents receiving PIDs were less often diagnosed with dementia than were residents receiving no PIDs. The three most prevalent PIDs were short-acting benzodiazepine in greater dosages than recommended, hydroxyzine, and nitrofurantoin. These three drugs accounted for nearly 77% of all PID use. Of all residents, less than 5% were susceptible to a clinically significant DDI. The most common DDIs were related to the use of potassium-sparing diuretics, carbamazepine, and codeine. Residents exposed to potential DDIs were younger, had more often suffered a previous stroke, more often used psychotropics, and were more often exposed to PIDs and polypharmacy than were residents not exposed to DDIs. Residents in private nursing homes were less often exposed to polypharmacy than were residents in public nursing homes. Long-term residents in nursing homes in Helsinki use, on average, nearly eight drugs daily. The use of psychotropic drugs in our study was notably more common than in international studies. The prevalence of laxatives equaled other prior international studies. Regardless of the known benefit and recommendation of vitamin D supplementation for elderly residing mostly indoors, the proportion of nursing home residents receiving vitamin D and calcium was surprisingly low. The use of PIDs was common among nursing home residents. PIDs increased the likelihood of DDIs. However, DDIs did not seem a major concern among the nursing home population. Monitoring PIDs and potential drug interactions could improve the quality of prescribing.

Nutrition and Nutritional Care of Elderly People in Finnish Nursing Homes and Hospitals

Background: Malnutrition is a common problem for residents of nursing homes and long-term care hospitals. It has a negative influence on elderly residents and patients health and quality of life. Nutritional care seems to have a positive effect on elderly individuals nutritional status and well-being. Studies of Finnish elderly people s nutrition and nutritional care in institutions are scarce. Objectives: The primary aim was to investigate the nutritional status and its associated factors of elderly nursing home residents and long-term care patients in Finland. In particular, to find out, if the nursing or nutritional care factors are associated with the nutritional status, and how do carers and nurses recognize malnutrition. A further aim was to assess the energy and nutrient intake of the residents of dementia wards. A final objective was to find out, if the nutrition training of professionals leads to changes in their knowledge and further translate into better nutrition for the aged residents of dementia wards. Subjects and methods: The residents (n=2114) and patients (n=1043) nutritional status was assessed in all studies using the Mini Nutritional Assessment test (MNA). Information was gathered in a questionnaire on residents and patients daily routines providing nutritional care. Residents energy and nutrient intake (n=23; n=21) in dementia wards were determined over three days by the precise weighing method. Constructive learning theory was the basis for educating the professionals (n=28). A half-structured questionnaire was used to assess professionals learning. Studies I-IV were cross-sectional studies whereas study V was an intervention study. Results: Malnutrition was common among elderly residents and patients living in nursing homes and hospitals in Finland. According to the MNA, 11% to 57% of the studied elderly people suffered from malnutrition, and 40-89% were at risk of malnutrition, whereas only 0-16% had a good nutritional status. Resident- and patient-related factors such as dementia, impaired ADL (Activities of Daily Living), swallowing difficulties and constipation mainly explained the malnutrition, but also some nutritional care related factors, such as eating less than half of the offered food portion and not receiving snacks were also related to malnutrition. The intake of energy and some nutrients by the residents of dementia wards were lower than those recommended, although the offered food contained enough energy and nutrients. The proportion of residents receiving vitamin D supplementation was low, although there is a recommendation and known benefits for the adequate intake of vitamin D. Nurses recognized malnutrition poorly, only one in four (26.7%) of the actual cases. Keeping and analysing food diaries and reflecting on nutritional issues in small group discussions were effective training methods for professionals. The nutrition education of professionals had a positive impact on the energy and protein intake, BMIs, and the MNA scores of some residents in dementia wards. Conclusions: Malnutrition was common among elderly residents and patients living in nursing homes and hospitals in Finland. Although residents- and patient related factors mainly explained malnutrition, nurses recognized malnutrition poorly and nutritional care possibilities were in minor use. Professionals nutrition education had a positive impact on the nutrition of elderly residents. Further studies describing successful nutritional care and nutrition education of professionals are needed.

Men´s health behaviour, health beliefs and need for health counselling : A study amongst 40-year-old males from one Helsinki City region

Tavoitteena oli tutkia 40-vuotiaiden miesten terveyskäyttäytymistä, terveysuskomuksia ja miesten saamaa terveysneuvontaa Helsingissä. 273 miestä vastasi kyselyyn ja osallistui terveystutkimuksiin. Terveydentilan perusteella miehet arvioitiin matalan (n=145) ja korkean (n=128) riskin ryhmiin. Khin neliö-testillä tutkittiin elämäntapa- ja riskitekijöitä koetun terveyden (hyvä, keskinkertainen/huono) luokissa ja verrattiin matalan ja korkean riskin ryhmiä em. tekijöiden osalta. Askeltavalla logistisella regressiomallilla analysoitiin tulosmuuttujia taustatekijöiden, terveyskäyttäytymisen, terveysuskomusten ja kliinisten riskitekijöiden avulla sekä arvioitiin oireiden ja vaivojen suhdetta koettuun terveydentilaan. Korkeassa riskissä olevien terveyttä seurattiin vuosina 2001–2004 analysoimalla mini-intervention vaikutusta terveysriskeihin ja elintapoihin varianssianalyysin avulla (ANOVA) (n=46). Matalasta vastausprosentista johtuen (39.6%), ei-vastanneiden aineistoa kerättiin käyttämällä syvähaastattelua (n=28) sekä puhelinkyselyä (n=40). Lopullinen aineisto koostui 341 miehestä. Tulokset osoittivat, että miehillä oli sydän- ja verisuonitautiriskejä. Kaksi kolmesta osallistuneista oli ylipainoisia tai lihavia, yli kolmanneksella vyötärönympärys oli ≥100 cm, ja yli 40%:llä oli diastolinen verenpaine ≥90 mmHg. Yli puolet tupakoi päivittäin ja 40% käytti alkoholia runsaasti. Ristiriitaisuutta ilmensi se, että huolimatta riskitekijöistä noin puolet miehistä koki terveydentilansa hyväksi. Sairauden tai vamman puute, hyvä suun terveydentila ja normaali vyötärönympärys olivat yhteydessä hyväksi koettuun terveydentilaan. Suora yhteys voitiin havaita omaisten tarjoaman neuvonnan ja vähäisen alkoholin käytön välillä. Masennus ja unettomuus olivat voimakkaasti yhteydessä loppuun palamiseen. Miehillä oli erilaisia fyysisiä ja psyykkisiä oireita, jotka korreloivat voimakkaasti masennuksen kanssa. Pieni määrä miehistä koki saaneensa terveysneuvontaa hoitohenkilökunnalta verrattuna perheenjäseniltä saatuun ohjaukseen. Korkeariskisten miesten (n=46) arvot parantuivat merkitsevästi lyhyellä aikavälillä. Kolesteroliarvoja lukuunottamatta ne palautuivat kolmen vuoden kuluttua alkumittausarvoja kohti. Laadullinen tutkimus osoitti, että “ei-vastanneet“ eivät osallistuneet projektiin, sillä he olivat oireettomia tai kiireisiä. Heillä todettiin samoja terveysriskejä kuin projektiin osallistuneilla. Syvähaastattelussa miehet toivat esille kokemuksiaan huolista, vihan tunteista, peloista ja yksinäisyydestä. Hoidonantajien on tärkeää ymmärtää ristiriidat miesten subjektiivisen ja objektiivisen terveydentilan välillä, mikä auttaa havaitsemaan esteitä terveyskäyttäytymiselle. Yhä enemmän tarvitaan yhteistyötä yksityisen ja julkisen terveydenhuollon välillä varmistamaan terveystottumusten jatkuminen miesten keskuudessa.

Spectral states and accretion geometries in Galactic black hole binaries

Black hole X-ray binaries, binary systems where matter from a companion star is accreted by a stellar mass black hole, thereby releasing enormous amounts of gravitational energy converted into radiation, are seen as strong X-ray sources in the sky. As a black hole can only be detected via its interaction with its surroundings, these binary systems provide important evidence for the existence of black holes. There are now at least twenty cases where the measured mass of the X-ray emitting compact object in a binary exceeds the upper limit for a neutron star, thus inferring the presence of a black hole. These binary systems serve as excellent laboratories not only to study the physics of accretion but also to test predictions of general relativity in strongly curved space time. An understanding of the accretion flow onto these, the most compact objects in our Universe, is therefore of great importance to physics. We are only now slowly beginning to understand the spectra and variability observed in these X-ray sources. During the last decade, a framework has developed that provides an interpretation of the spectral evolution as a function of changes in the physics and geometry of the accretion flow driven by a variable accretion rate. This doctoral thesis presents studies of two black hole binary systems, Cygnus~X-1 and GRS~1915+105, plus the possible black hole candidate Cygnus~X-3, and the results from an attempt to interpret their observed properties within this emerging framework. The main result presented in this thesis is an interpretation of the spectral variability in the enigmatic source Cygnus~X-3, including the nature and accretion geometry of its so-called hard spectral state. The results suggest that the compact object in this source, which has not been uniquely identified as a black hole on the basis of standard mass measurements, is most probably a massive, ~30 Msun, black hole, and thus the most massive black hole observed in a binary in our Galaxy so far. In addition, results concerning a possible observation of limit-cycle variability in the microquasar GRS~1915+105 are presented as well as evidence of `mini-hysteresis' in the extreme hard state of Cygnus X-1.

Consequences of Vertebral Fractures

Vertebral fractures occur due to forces applied to spinal structures. When the bone tissue is weakened, vertebral fractures can result from a minor trauma. Adult vertebral fractures are commonly considered to be an indication for osteoporosis. In children osteoporosis is a rare condition, and pediatric vertebral fractures are usually clearly trauma-related. The aims of this dissertation are to produce knowledge of the epidemiology of osteoporotic vertebral fractures and to analyse their association with total and cause-specific mortality, to find indicators with which to identify individuals who are at great risk of subsequent fractures, to study the incidence of pediatric vertebral fractures and need for their operative treatment and hospital care. The Mobile-Clinic and Mini-Finland Health surveys of the adult population were used as materials in this research. Record linkages to the Finnish Hospital Discharge Register and the Official Cause of Death register were used to study mortality and hospitalization in the same population group. These registers were also used to evaluate epidemiology, mortality, hospitalization and the need for operative management of pediatric vertebral fracture patients. The main findings and conclusions of the present dissertation are: 1. The presence of a thoracic vertebral fracture in adults is a significant predictor of cancer and respiratory mortality. In women, but not in men, vertebral fractures strongly predict mortality due to injuries. Most of these deaths in the study group were hip fracture related. 2. Severe thoracic vertebral fracture in adults was a strong predictor of a subsequent hip fracture, whereas mild or moderate fractures and the number of compressed vertebrae were much weaker predictors, 3. Pediatric spinal fractures were rare: The incidence was 66 per one million children per year. In younger children cervical spine was most often affected, whereas in older children fractures of the thoracic and lumbar spine were more common. Maturation of spinal structures seems to play a major role in the typical injury patterns in children. Thirty per cent of pediatric spinal fractures required surgical treatment. The current study focuses on consequences of vertebral fractures in general, without evaluating further the causation of the studied phenomena. Further studies are needed to clarify the mechanisms of association between vertebral fractures and specific causes of mortality. A severe vertebral fracture appears to indicate a substantial risk of a subsequent hip fracture. If such a fracture is identified from a chest radiograph, urgent clinical evaluation, treatment of osteoporosis and protective measures against falls are recommended.

Akateemisten pätkätyöläisten hyvinvointi ja kuntoutus. TUULI-kehittämishankkeen arvioinnin loppuraportti

Määräaikaisiin työsuhteisiin liittyvä epävarmuus on useiden tutkimusten mukaan yhteydessä stressiin ja vähentää psyykkistä hyvinvointia. Suomessa määräaikaiset työsuhteet ovat hieman yleisempiä kuin EU:ssa keskimäärin. Erityistä Suomen tilanteelle on se, että suomalaiset määräaikaiset palkansaajat ovat varsin koulutettuja eurooppalaisiin vertaisiinsa verrattuna. Yliopistoissa poikkeuksellisen suuri osa tekee työtä määräaikaisessa työsuhteessa. TUULI-kehittämishanke (2008–2011) toteutettiin Kuntoutussäätiön Malminkartanon kuntoutuskeskuksessa (syksystä 2010 Avire-Kuntoutus Oy), ja se oli tarkoitettu Helsingin yliopistossa määräaikaisissa palvelussuhteissa tai apurahalla työskenteleville henkilöille. Hankkeen rahoittivat Kela ja Työsuojelurahasto. Hankkeen arviointi toteutettiin Kuntoutussäätiön tutkimus- ja kehittämisyksikössä, ja arvioinnin rahoitti Kela. Hanke liittyi laajempaan Kelan toteuttamaan työhönkuntoutuksen kehittämishankkeeseen. Kuntoutusmalli TUULIn kohderyhmänä olivat Helsingin yliopiston akateemisesti koulutetut henkilöt, jotka ovat määräaikaisissa ja usein projektiluonteisissa työtehtävissä. Tämän kohderyhmän kuntoutustarvetta ei arvioida systemaattisesti työterveyshuollossa eikä työvoimatoimistossa. Osa kohderyhmään kuuluvista henkilöistä ei ole oikeutettu käyttämään työterveyshuollon palveluja, ja määräaikaisten työsuhteiden vuoksi he eivät myöskään valikoidu varhaiskuntoutukseen. Kuntoutusmalli TUULIn tavoitteena oli löytää kohderyhmälle soveltuvia kuntoutustarpeen arviointikeinoja (hyvinvointianalyysi). Tavoitteena oli myös kehittää kohderyhmälle soveltuva varhaiskuntoutusmuoto, johon määräaikaisissa työsuhteissa olevien on käytännössä mahdollista osallistua. Arvioinnissa keskeistä oli kehittävä arviointi, toisin sanoen tavoitteena oli myös tukea hankkeen toimintaa sen tavoitteiden toteuttamisessa ja kuntoutusmallin kehittämisessä. Arviointitutkimuksen tavoitteena oli tuottaa kokonaisarviointi TUULI-kuntoutusmallista. Hankkeen aluksi koottiin perustiedot sekä varsinaiseen interventioon osallistuvilta että ainoastaan hyvinvointianalyysiin osallistuneilta asiakkailta. Myös hankkeen päättyessä koottiin seurantatiedot molemmilta ryhmiltä. Jokainen kuntoutusryhmä on lisäksi haastateltu viimeisen seitsemän vuorokauden intensiivijaksoon kuuluvan päivän aikana. Arvioinnin aikana tehtiin osallistavaa yhteistyötä erityisesti hankkeen toteuttajien, ohjausryhmän ja rahoittajatahojen kanssa. Hyvinvointianalyysiin ja kuntoutusinterventioon saatiin rekrytoitua tavoiteltu määrä osallistujia. He kokivat määräaikaisuuteen liittyvän epätietoisuuden haittaavan työssä jaksamista. Hieman vajaa kolmasosa koki tämän haittaavan paljon. Selvä enemmistö raportoi työn henkisen kuormituksen ongelmista. Hyvinvointianalyysin ohjelma koostui sydämen sykevariaatioanalyysistä, psykologisista testeistä, lääkärin tutkimuksesta ja palautekeskustelusta. Hyvinvointianalyysi koettiin osallistujien keskuudessa varsin hyödylliseksi toimenpiteeksi. Koettu hyöty näyttäisi olevan samalla tasolla myös yhdeksän kuukautta hyvinvointianalyysin päättymisestä. Hyvinvointianalyysi toimi kuntoutustarpeen arviointivälineenä ja itsenäisenä mini-interventiona. Kuntoutusinterventiossa keskeisiä osa-alueita olivat stressin hallinnan ja rentoutumisen opetteleminen, oman työn kuormitustekijöiden tunnistaminen sekä psyykkisen hyvinvoinnin ja omien voimavarojen vahvistaminen. Myös kuntoutusintervention jälkeen osallistujien kokemukset olivat enimmäkseen positiivisia: he kokivat intervention kohentavan kykyään huolehtia omasta hyvinvoinnistaan sekä vahvistavan psyykkisiä ja sosiaalisia voimavarojaan ja stressin hallintaa. Myös työkyvyn koettiin kohentuneen. Sen sijaan osallistujat eivät kokeneet toiminnan ja työn tehokkuuden taitojen kohenneen. Toteuttajat arvioivat hankkeen saavuttaneen keskeisimmät tavoitteensa. Pätkätyöläisen ammatillisen identiteetin hahmottaminen ja työstäminen koettiin ongelmalliseksi; kehittämishankkeen aikana ei löydetty varteenotettavaa lähestymistapaa aiheeseen. Kuntoutusjärjestelmää tulee kehittää huomioiden työn ja työelämän muutokset. TUULI-hanke oli hyvä avaus tällä saralla, mutta hanke oli suunnattu vain pienelle osalle epätyypillistä työtä tekevien joukkoa. Koska määräaikainen työ on vakiintunut osaksi työmarkkinoita ja pätkistä koostuvaan työuraan liittyy työttömyysjaksoja, tulisi myös työttömyyskaudella olevat saada kuntoutusjärjestelmän piiriin. Arvioinnin kehittämissuositukset huomioiva TUULI-kuntoutusmalli tulisi toteuttaa ainakin kertaalleen Suomen yliopistoissa.

Tumorigenesis in celiac disease

Celiac disease is life-long autoimmune disorder of the small intestine, which is caused by a reaction to gliadin found in wheat, rye and barley in genetically predisposed individuals. Proline- and glutamine -rich proteins cause villous atrophy and crypt hyperplasia with extensive inflammation in the epithelium and lamina propria. Symptoms of celiac disease vary considerably and elimination of gluten from diet is the only way to treat disease. In small intestine of celiac disease patient transglutaminase 2 (TG2) modifies gluten peptides, which causes T-cell activation and inflammation in the epithelium of mucosa. T-cell activation induces development of celiac disease specific antibodies. These celiac disease specific antibodies recognise TG2 and interfere in vitro and in vivo in angiogenesis. Abnormal angiogenesis is typical in many disorders, such in cancer, in which TG2 has a crucial role in the development and growth of tumor. Overexpression of TG2 has been shown to correlate with accelerated growth of tumor. TG2-specific antibodies are suggested to inhibit differentation of epithelial cell, increase their proliferation, decrease their barrier-function and increase the permeability of blood vessels. The aims of the pilot study were to establish whether celiac disease TG2 antibodies affect in vivo tumorigenesis and tumorangiogenesis as well as to try to clarify the mechanism behind the phenomenon. Tumor xenograft model was used in severe combined immunodeficient (SCID) mice. Human oesophageal carcinoma (OE-19) cancer cells were incubated with celiacs TG2 miniautoantibody (mini 2.8), non-celiac miniautoantibody (mini 6.2) or PBS before cancer cells were injected to mice subcutaneously. During the experiment mice were weighted and tumor size was measured couple of times per week. To estimate the volumes of tumors the following formula was used: π/6 * L* W* H. Experiment lasted for four weeks after which the mice were euthanized, cardiac blood and tissue samples taken and tumours were excised and weighted. Sections were made from tumors and immunohistochemical stainings were done to compare blood vessel areas and to study general tumors´morphology and other parameters. Western blot -analyse were performed to cancer cells. The masses and volumes were clearly smaller in mini 2.8-group compared to control groups and the necrotic area of tumor in mini 2.8 was smallest as percentage compared to control groups. Blood vessel area were smallest in mini 2.8 group. Results suggest that celiac disease anti-TG2-autoantibodies inhibit tumor growth, but the number of animals is insufficient to give an accurate outcome.
