    Ihmisen kokonaistilanne on tärkeä ottaa hoidossa ja kuntoutuksessa huomioon. Psychosocial Factors Relevant to Brain Disorders in Europa (PARADISE) -hanke toteutettiin kymmenen instituutin yhteistyössä professori Ciezan johdolla 2010–2013. Tavoitteena oli kehittää tutkimukseen perustuva menetelmä, jonka avulla voidaan kartoittaa psykososiaalisia vaikeuksia eri aivotoiminnan häiriöiden hoidossa, kuntoutuksessa ja tutkimisessa. Hankkeessa oli lähtökohtana oletus psykososiaalisten vaikeuksien horisontaalisesta epidemiologiasta. Hankkeessa tutkittiin yhdeksää aivotoiminnan häiriötä: dementiaa, depressiota, epilepsiaa, migreeniä, MS-tautia, Parkinsonin tautia, skitsofreniaa, aivoverenkiertohäiriötä ja päihderiippuvuutta. Kunkin häiriön osalta toteutettiin systemaattinen kirjallisuuskatsaus ja fokusryhmähaastattelu. Esiin nousseet psykososiaaliset vaikeudet luokiteltiin ja linkitettiin kansainväliseen toimintakykyluokitukseen (ICF). Eri häiriöille yhteisten 64 psykososiaalisen vaikeuden yleisyyttä ja intensiteettiä tutkittiin yksilöhaastatteluissa (n = 722). Tulosten pohjalta muodostettiin yleisiä psykososiaalisia vaikeuksia mahdollisimman laajasti kattava PARADISE24-kysely. Oletus eri häiriöiden yhteisistä psykososiaalisista ongelmista osoittautui todeksi. Kyselyyn valikoitui neljätoista kysymystä ICF:n osa-alueelta b Ruumiin/kehon toiminnot ja kymmenen kysymystä osa-alueelta d Suoritukset ja osallistuminen. Psykososiaalisten vaikeuksien intensiteetissä esiintyi kuitenkin häiriöiden välillä eroja siten, että psykiatristen tai päihdehäiriöiden takia haastatellut käyttivät laaja-alaisesti viisiportaista vastausvaihtoehtojen asteikkoa, mutta neurologisten häiriöiden yhteydessä kaksi- tai kolmeportainen asteikko vaikutti riittävältä. PARADISE24-kysely sisältää olennaiset kysymykset, mutta jatkotutkimusta tarvitaan erityisesti kyselyn toimivuudesta seurantakäytössä. Raportissa esitetään PARADISE24-kyselyn valmistamisen tutkimusperusta horisontaalisten tulosten sekä erikseen päihdehäiriöiden näkökulmasta.36,00 euro

    We present a floating catalyst synthesis route for individual, i.e., non-bundled, small diameter single-walled carbon nanotubes (SWCNTs) with a narrow chiral angle distribution peaking at high chiralities near the armchair species. An ex situ spark discharge generator was used to form iron particles with geometric number mean diameters of 3–4 nm and fed into a laminar flow chemical vapour deposition reactor for the continuous synthesis of long and high-quality SWCNTs from ambient pressure carbon monoxide. The intensity ratio of G/D peaks in Raman spectra up to 48 and mean tube lengths up to 4 μm were observed. The chiral distributions, as directly determined by electron diffraction in the transmission electron microscope, clustered around the (n,m) indices (7,6), (8,6), (8,7), and (9,6), with up to 70% of tubes having chiral angles over 20°. The mean diameter of SWCNTs was reduced from 1.10 to 1.04 nm by decreasing the growth temperature from 880 to 750 °C, which simultaneously increased the fraction of semiconducting tubes from 67% to 80%. Limiting the nanotube gas phase number concentration to ∼10 exp 5 cm exp −3 prevented nanotube bundle formation that is due to collisions induced by Brownian diffusion. Up to 80% of 500 as-deposited tubes observed by atomic force and transmission electron microscopy were individual. Transparent conducting films deposited from these SWCNTs exhibited record low sheet resistances of 63 Ω/□ at 90% transparency for 550 nm light.Peer reviewe

    Objective To test the hypothesis of ‘horizontal epidemiology’, i.e. that psychosocial difficulties (PSDs), such as sleep disturbances, emotional instability and difficulties in personal interactions, and their environmental determinants are experienced in common across neurological and psychiatric disorders, together called brain disorders. Study Design A multi-method study involving systematic literature reviews, content analysis of patientreported outcomes and outcome instruments, clinical input and a qualitative study was carried out to generate a pool of PSD and environmental determinants relevant for nine different brain disorders, namely epilepsy, migraine, multiple sclerosis, Parkinson’s disease, stroke, dementia, depression, schizophrenia and substance dependency. Information from these sources was harmonized and compiled, and after feedback from external experts, a data collection protocol including PSD and determinants common across these nine disorders was developed. This protocol was implemented as an interview in a cross-sectional Objective To test the hypothesis of ‘horizontal epidemiology’, i.e. that psychosocial difficulties (PSDs), such as sleep disturbances, emotional instability and difficulties in personal interactions, and their environmental determinants are experienced in common across neurological and psychiatric disorders, together called brain disorders.

    Psychosocial difficulties in alcohol dependence: a systematic review of activity limitations and participation restrictions

    Abstract Purpose: There has been a lack of comprehensive reviews targeting specific aspects of functioning and the difficulties faced by persons with alcohol dependence. The aim of the present review was to systematically compile the existing literature on activity limitations and participation restrictions as defined in the International Classification of Functioning, Disability and Health (ICF) in the context of alcohol dependence. Methods: A database search (MEDLINE and PsychINFO) was performed for studies published in English (2005-2012), examining the activity limitations and participation restrictions in alcohol dependence. Using a standardised protocol, information about the studies' characteristics and data on activity limitations and participation restrictions, their evolution, onset, determinants and associations with other variables were extracted from the studies under review. Results: A total of 211 difficulties in activities and participation in persons with alcohol dependence were extracted from 125 papers. The spectrum of studies was wide, and their overall quality was good. A common reason for the exclusion of studies was an inconclusive definition of alcohol dependence. Issues with interpersonal interactions, economic and professional life, dealing with aggression and legal problems were the most frequently reported difficulties. Problems with high-risk behaviours and in seeking appropriate treatment were also common. The most frequent determinants of the onset and evolution of the identified difficulties were factors pertaining to the course of alcohol dependence. These difficulties were rarely the studies' focus; therefore, the data on their underlying causes and courses were limited. Conclusions: The results confirm that alcohol dependence profoundly affects the family and social network of the afflicted person. The treatment of alcohol dependence can contribute to the alleviation of these associated difficulties. The ICF offers a new perspective on evaluating the wide range of difficulties encountered in the context of alcohol dependence. Implications for Rehabilitation Alcohol dependence profoundly affects the family and social network of the afflicted person. The most frequent difficulties in activities and participation have to do with interpersonal interactions, economic and work life, dealing with aggression and legal problems. Problems with high-risk behaviours and in seeking appropriate treatment are also common. Treatment targeted at reduction or cessation of alcohol use is effective in reducing these psychosocial difficulties. The ICF offers a structure for systematic evaluation of the wide range of difficulties encountered in alcohol dependence.<br/
