Akuttmedisinske situasjoner krever rask, god og effektiv kommunikasjon. Publikum har i økende grad mulighet for videokonferanse via vanlige mobiltelefoner. Kan legfolk i fremtiden få bedre hjelp fra medisinsk nødnummer (113) hvis de kan vise levende bilder fra akuttmedisinske situasjoner via mobiltelefonen? Dette er hovedspørsmålet i dette doktorgradsarbeidet utført ved Nasjonalt senter for samhandling og telemedisin og Akuttmedisinsk klinikk ved Universitetssykehuset Nord-Norge. 180 elever fra videregående skoler i Tromsø deltok som legfolk ved simulerte hjertestans. Under forsøkene kommuniserte elevene med AMK-sykepleiere på medisinsk nødnummer (113). Kommunikasjonen skjedde ved hjelp av to typer mobiltelefoner: vanlige mobiler med kun tale, eller mobiler med både tale og toveis bildeoverføring (video). Tidsbruk og kvaliteten på gjennomført gjenoppliving ble målt på gjenopplivingsdukker i en randomisert kontrollert studie. Sykepleierne ble intervjuet og studentene besvarte et spørreskjema etter forsøkene. Et panel sammensatt av ulike fagprofesjoner utførte risikoanalyse av informasjonssikkerheten for videokonferanse via mobiltelefoner mellom legfolk og medisinsk nødnummer (113). Ifølge sykepleierne som deltok i forsøkene ga videokonferanse økt kvalitet på kommunikasjonen med legfolk, og enklere veiledning når de kunne se både «pasienten» og gjenopplivingsforsøkene. Sykepleierne mente derfor videokonferanse kan gi økt trygghet, spart tid og bedre behandling. Kvaliteten på videokonferansen var for dårlig i disse forsøkene til å gi tydelige forskjeller i gjennopplivingskvaliteten, men legfolk følte det tryggere å ha visuell kontakt med AMK-operatørene. Risikoanalyse av denne teknologien avdekket ikke uakseptable risiki mot informasjonssikkerheten. Nye mobiltelefoner med videotelefoni og bedre teknologi vil kunne gi bedre kvalitet på nødkommunikasjonen og gjenopplivning i akuttsitusjoner. Reelle hendelser må studeres for å finne hvordan billedkommunikasjon best kan utnyttes i akuttmedisinske situasjoner. Medical emergencies require rapid, effective and good communication. The public has increasing possibilities for video conferencing over regular cell phones. Can lay people in the future get better help from emergency medical dispatch centers if they can transmit live images from medical emergencies via cell phones? This is the main question in this doctoral thesis conducted at the Norwegian Centre for Integrated Care and Telemedicine and Division of Trauma Care and Pre-Hospital Services at the University Hospital of North Norway, Tromsø, Norway. One hundred eighty high schools students from Tromsø participated in simulated cardiac arrest. During the tests the students communicated with dispatcher nurses. The communication took place using two types of mobile phones: regular phones with just voice, or telephones with voice and two-way video transmission. A resuscitation manikin was used to measure duration and quality of resuscitation in a randomized controlled trial. After the effort, participants were interviewed or answered a questionnaire. A risk analysis was performed for the information security of video dispatch. According to the dispatchers, videoconferencing improved the quality of communication, and supervision became easier when they could see both the "patient" and resuscitation attempts. The dispatchers thought videoconferencing can provide increased confidence, time savings and better treatment. The quality of the video conference was not sufficient in these trials to provide clear differences in resuscitation quality, but lay people felt more safe when they had visual contact with the dispatchers. The risk analysis of this technology revealed no unacceptable risks to information security. Video enabled mobile phones and improved communication technology may provide better quality of communication and resuscitation in medical emergencies. Actual events must be studied to determine how visual communication best can be utilized in emergency medical situations.

Prognostic Impacts of Angiopoietins in NSCLC Tumor Cells and Stroma : VEGF-A Impact Is Strongly Associated with Ang-2
Andersen, Sigve; Dønnem, Tom; Al-Shibli, Khalid Ibrahim; Al-Saad, Samer; Stenvold, Helge; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Angiopoietins and their receptor Tie-2 are, in concert with VEGF-A, key mediators in angiogenesis. This study evaluates the prognostic impact of all known human angiopoietins (Ang-1, Ang-2 and Ang-4) and their receptor Tie-2, as well as their relation to the prognostic expression of VEGF-A. 335 unselected stage I-IIIA NSCLC-patients were included and tissue samples of respective tumor cells and ... -
The Temporomandibular Joint in Juvenile Idiopathic Arthritis, focusing on Quality of Life, Oral Microbiome and Intervention
Frid, Paula (Doctoral thesis; Doktorgradsavhandling, 2020-10-02)The temporomandibular joint (TMJ) is commonly involved in juvenile idiopathic arthritis (JIA), and may lead to impaired mouth opening, pain and facial growth disturbances. Asymptomatic TMJ arthritis may be diagnosed late in the disease course, thus management is challenging. The overall objectives of this thesis were to provide new knowledge on quality of life (QoL), the oral microbiome and interventions ... -
Humant papillomavirus : en litteraturstudie om HPV, dets relasjon til cancer og tiltak mot videre spredning av virus
Gabrielsen, Endre (Master thesis; Mastergradsoppgave, 2012-06-01)I 1983 oppdaget zur Hausen sammenhengen mellom Humant Papillomavirus (HPV) og livmorhalskreft. På denne tiden visste man ikke at det var HPV som var årsaken til at Helaceller kunne leve in vitro. Ny forskning relaterer HPV til en rekke andre cancertyper. En stor andel anal-, oropharyngeal-, penis-, vaginal-, og vulvacancer skyldes HPV. Det er også påvist HPV i tumorvev fra øsofagus, larynx, lunge, ...
