    As many countries are transitioning from cytology to human papillomavirus (HPV) testing as the primary cervical cancer screening test, we evaluated the impact of cumulative HPV screening during the implementation of HPV screening in the Norwegian cervical cancer screening programme (CervicalScreen Norway). Data from the second HPV screening round was compared with data from the first round. The second-round analyses included only women who returned to routine screening 4–6 years following a negative HPV test in the first round. Associations between screening rounds and HPV positivity, cytology results, and follow-up recommendations were estimated by multinomial logistic regression, and relative risks of cervical intraepithelial neoplasia, grade 3 or worse (CIN3+) by Cox regression. There was a 42% lower risk of being HPV positive in the second screening round compared to the first (age-adjusted relative risk ratio (aRRR) 0.58, 95% confidence interval (CI) 0.53 to 0.65), and a 70% lower risk of having high-grade cytology among HPV16 positive women (0.30, 0.12 to 0.78). There was also a 51% reduction in referrals for immediate colposcopy (0.49, 0.39 to 0.62). The overall risk of CIN3+ was 71% lower in the second round compared to the first (age-adjusted hazard ratio [aHR] 0.29, 95%CI 0.21–0.40), and lower among HPV16 and other high-risk HPV positive women, but not among HPV18 positives. No cervical cancers were diagnosed in the second round (mean follow-up 2.4 years). Our findings indicate that HPV test results from previous screening rounds should be considered when designing optimal screening algorithms.publishedVersio

    Applying current European periodontitis clinical practice guidelines is not feasible even for the richest countries in the world

    Get PDF
    Clinical practice guidelines aim to enhance the quality, equality and consistency of care but often demand more time than is available, rendering adherence impractical and exceeding feasible resources. The 2017 introduction of a new periodontal classification system by the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP) sought to refine clinical and epidemiological practices by serving as the basis for clinical practice guidelines and epidemiological investigations around the world. Following this classification, the EFP recommends supportive periodontal care visits every 3–12 months for all periodontitis cases. Given that in Norway, approximately 72% of the adult population are identified as periodontitis cases under the current AAP/EFP case definition, this poses a significant demand on healthcare resources. We calculated that between 60% and 70% of all estimated available working hours available for adult dental care provided by dentists and dental hygienists in Norway in 2017 would be spent on supportive periodontal care visits alone if the recommendations were to be met. This situation calls for a reevaluation of disease definitions and clinical practice guidelines to ensure they are practical, financially feasible and patient-outcome relevant.publishedVersio

    Cognitive behavioral therapy for insomnia across the spectrum of alcohol use disorder: A systematic review and meta-analysis

    Get PDF
    Insomnia is prevalent among patients with alcohol use disorder (AUD), potentially undermining treatment and increasing the risk of relapse. Cognitive behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment for insomnia, but its efficacy is not well-characterized in patients across the spectrum of AUD. The aim of this meta-analysis was to quantify the effectiveness of CBT-I in improving insomnia severity and alcohol-related outcomes in adults with heavy alcohol use and/or varying levels of AUD severity and comorbid insomnia. MEDLINE, Cochrane Library, PsycINFO and ClinicalTrials.gov were systematically searched (up to February 2024) to retrieve randomized controlled trials (RCTs). Multilevel meta-analyses were conducted to estimate mean differences over time in insomnia severity, measured using the Insomnia Severity Index (ISI), as well as in alcohol craving and alcohol-related psychosocial problems between CBT-I and control groups. For the number of heavy-drinking/abstinent days, incidence rate ratios were estimated. Risk of bias was assessed using the Risk of Bias 2 (RoB 2) tool. Eight RCTs encompassing 426 adults (68.78 % men) were included. Compared with control conditions, CBT-I resulted in a large reduction of insomnia severity post-treatment [estimated ISI reduction = −5.51, 95% CI (−7.13 to −3.90)], which was maintained at 1-to-3-month [7 studies; estimate = −4.39, 95% CI (−6.08 to −2.70)], and 6-month follow-up [4 studies; estimate = −4.55, 95% CI (−6.77 to −2.33)]. Alcohol-related outcomes were reported less consistently, and no significant differences were found. The included trials were judged to have a low or moderate overall risk of bias for the assessment of all outcomes. CBT-I effectively reduces insomnia severity across the spectrum of AUD, supporting wide implementation in AUD prevention and treatment settings.publishedVersio

    «Han skulle ønske at de så hva han var god til» En instrumentell casestudie om hvordan musikkterapi kan bidra til å styrke relasjonsarbeid og identitetsarbeid hos barn og unge i barnevernet.

    Get PDF
    Barn og unge i barnevernet beskrives ofte som en sårbar gruppe, med behov for trygge relasjoner og muligheter til identitetsutvikling. Forskning har vist at musikkterapi kan være relevant for denne gruppen, men det finnes fortsatt behov for mer kunnskap om hvordan musikkaktiviteter kan bidra til relasjonsarbeid og identitetsarbeid i barnevernet. Formålet med mitt masterprosjekt har vært å undersøke hvordan musikkterapi kan styrke relasjoner og identitetsutvikling blant barn og unge i barnevernet. Studiens problemstilling er: Hvordan kan musikkterapi bidra til å skape trygge rammer og muligheter for relasjonsarbeid og identitetsarbeid i barnevernet? I denne studien har jeg analysert caser fra barnevernet for å få et dypere innblikk i hvordan musikkaktiviteter kan fungere i praksis. Min analytiske tilnærming har vært kvalitativ, med fokus på å forstå og tolke casenes innhold. Gjennom analysen har jeg identifisert flere temaer, blant annet hvordan musikk skaper trygge rammer, gir rom for selvuttrykk, og fremmer tillitsfulle relasjoner mellom barn og voksne. Teoretisk har jeg benyttet perspektiver knyttet til relasjonsarbeid, identitetsutvikling og brukermedvirkning, samt relevant barnevernsforskning. Mine funn viser at musikkterapi kan bidra til å skape trygge, helhetlige rammer hvor barn og unge får mulighet til å uttrykke seg, bygge tillit og utvikle sin identitet. Musikkaktiviteter fremmer også tverrfaglig samarbeid og gir rom for barns medvirkning. Til slutt peker jeg på behovet for mer forskning på barns egne perspektiver og langtidseffekter av musikkterapi i barnevernet.Children and young people in child welfare services are often described as a vulnerable group, with a need for safe relationships and opportunities for identity development. Research has shown that music therapy can be relevant for this group, but there is still a need for more knowledge about how music activities can contribute to relational and identity work in child welfare. The aim of my master’s project has been to examine how music therapy can strengthen relationships and identity development among children and young people in child welfare. The research question is: How can music therapy contribute to creating safe environments and opportunities for relational and identity work in child welfare? In this study, I have analyzed cases from child welfare to gain a deeper understanding of how music activities can function in practice. My analytical approach has been qualitative, with a focus on interpreting the content of the cases. Through the analysis, I have identified several themes, including how music creates safe environments, provides space for self-expression, and promotes trusting relationships between children and adults. Theoretically, I have used perspectives related to relational work, identity development, and user participation, as well as relevant child welfare research. My findings show that music therapy can help create safe, holistic environments where children and young people could express themselves, build trust, and develop their identity. Music activities also promote interdisciplinary collaboration and give space for children’s participation. Finally, I point to the need for more research on children’s own perspectives and the long-term effects of music therapy in child welfare.Masteroppgave i barnevernMABARN35

    The Völsung Ballads from the Faroe Islands in English Translation

    Get PDF
    This volume presents a collection of the Faroese ballads about the Völsung hero Sjúrður, the pre-eminent dragon-slaying hero of the Germanic Middle Ages, in English translation accompanied by the Faroese original. The ballads show that far from being culturally isolated, the Faroe Islands were an integral part of the Germanic storytelling tradition in the Middle Ages and later. The in-depth introduction explores the Faroese storytelling tradition as preserved in the ballads, which are still danced and performed today, and highlights the vibrancy of the tradition in contemporary culture. The publication and research history of the Faroese ballads is outlined, and summaries of each ballad are provided. These translations are an essential resource for anybody interested in medieval heroic literature.publishedVersio

    The Right to Be Exempted on Religious Grounds in Icelandic Basic Education: A Case for Further Study

    Get PDF
    This article examines Iceland’s scheme for educational exemptions based on religion, life philosophies, or personal convictions, comparing it with the schemes used in Norway, Sweden, and Denmark. Despite curricular reforms promoting inclusivity, Christian favouritism persists in Icelandic schools, often embedded in traditions classified as cultural rather than religious. The requirement for “valid arguments” in Iceland’s exemption process raises concerns over the law’s ambiguity and potential conflict with human rights law, specifically, the European Court of Human Rights’ emphasis on individual thought and conscience. This lack of clarity may deter parents and pupils from seeking exemptions and infringe upon privacy and religious freedom rights. The study underscores the need to refine exemption schemes to better protect individual rights while upholding educational integrity. It advocates for ongoing research into the right to be exempted in the Icelandic context.publishedVersio

    Addressing implementation uncertainty in postdischarge malaria chemoprevention : Determinants of adherence, cost-effectiveness, and the value of further research in Malawi and other malaria-endemic African countries

    Get PDF
    Postponed access: the file will be accessible after 2025-11-08Bakgrunn: Malaria fortsetter å være en ledende årsak til dødsfall og dødelighet for barn som bor i malaria-endemiske områder i Afrika sør for Sahara. Verdens helseorganisasjon (WHO) anbefaler chemoprevention av malaria for sårbare under-grupper som en strategi for å redusere forekomst av regional stagnerende malaria- og dødelighetsrater. Postdischarge malaria chemo-prevention (PDMC) består av husholdningsbasert oral antimalariabehandling for førskolebarn i endemiske områder i månedene etter recovery/bedring etter mottatt sykehusbehandling for alvorlig anemi. Tre måneder av PDMC reduserte risiko for dødelighet og readmission/gjeninnleggelse på sykehus substansielt. Basert på tilgjengelig bevis/funn/resultater anbefalte nylig WHO at land adopterer PDMC i malaria-endemiske områder. Denne avhandlingen hadde som mål å adressere de resterende kunnskapshull som lovgivere i afrikanske land sør for Sahara møter når de vurderer implementering av PDMC: faktorer for omsorgsgiveres adherence/etterlevelse til PDMC i Malawi, økonomisk evaluering av ulike delivery/leverings? strategier i sørøstlige afrikanske settinger, og verdien av videre informasjon for afrikanske land sør for Sahara ble analysert. Datakilder: Data fra en efficacy trial i Kenya og Uganda (n=1040) og en delivery trial i Malawi (n=375), gjennomført fra 2016 til 2018 ble brukt til de tre analysene og komplimentert med data fra litteraturen. Begge trials brukte tre måneder med månedlig dihydroartemisinin-pipereaquine (DHAP) til PDMC. The efficacy trial/studien sammenlignet PDMC med placebobehandling. The delivery trial sammenlignet community-delivered PDMC, hvor den totale mengden på ni doser av DHAP ble distribuert til omsorgsgivere ved utskriving fra sykehus med ‘facility-delivered’ PDMC, hvor tre månedsdoser ble hentet månedlig fra sykehuset. Metoder: Modified Poisson regresjonsanalyse ble brukt for å forutsi omsorgsgiveres adherence/etterlevelse basert på barn, omsorgsgiver, og husholdningskarakteristikker (predictor analyse, artikkel 1). Resultatene ble rapportert som relativ risiko for komplett etterlevelse. Kost-nytte-analysen (CEA, artikkel 2) brukte Markov decision modell for å sammenligne to leveringsstrategier av PDMC med standard of care for Malawi, Kenya og Uganda. Societal costing perspective ble tatt og resultatene ble rapportert som trinnvis kost-nytte ratio per kvalitets-justert liv-år oppnådd. I en value of information analyse (VOI, artikkel 3) kalkulerte vi per-decision net monetary benefit (NMB) for Kenya, Uganda og Malawi av perfekt og delvis perfekt informasjon for inputvariablene av CEA. Et scenario med halverte etterlevelsesrater for å simulere implementeringsbetingelser fra real-world ble inkludert. Resultatene ble/er rapportert som årlig per land NMB av perfekt informasjon og anvendt til 27 andre afrikanske land sør for Sahara, justert for variasjon i terskel for kjøpekraft og villighet til å betale. Resultater og tolkning: Det ble ikke funnet konkluderende sett av determinants/faktorer? for PDMC etterlevelse. En sosioøkonomisk indeks viste blandet assosiering på tvers av kvintiler med lav etterlevelse. Barn med fire eller fler malariainfeksjoner før innleggelse ble assosiert med redusert etterlevelse. PDMC kombinerer flere faktorer som kompliserer etterlevelsesatferd, og vi foreslår at etablerte spådde faktorer for adherence/etterlevelse av mindre komplekse regimer har svakere eller mer komplekse assosiasjoner med adherence/etterlevelse av PDMC. CEA viste at PDMC var kostnadsbesparende og mer effektivt enn standard of care. Community-delivered PDMC var den kostnadseffektive strategien i alle land, som ble bekreftet med sensitivitetsanalyse. Det robuste resultatet foreslår at PDMC er kostnadseffektivt og at å distribuere en komplett course av PDMC ved utskrivelse er den optimale delivery/leverings? strategien for malaria-endemiske sør-østlige afrikanske settinger. VOI analysen bekreftet dette resultatet ved å identifisere kun to kategorier av modellinput med usikkerheter som hadde en potensiell effekt på avgjørelsen av den optimale delivery/leverings? strategien: den relative dødelighetsraten ved å motta PDMC sammenlignet med standard of care og etterlevelsesraten.

The WHO recommends chemoprevention of malaria in vulnerable sub-populations as strategy to reduce the regionally stagnating malaria incidence and mortality rates. Postdischarge malaria chemoprevention (PDMC) comprises household-based oral antimalarial treatment of preschool children in endemic areas during the months of recovery after they were treated in hospital for severe anaemia. Three months of PDMC substantially reduce the risk of mortality and hospital readmission. Based on the available evidence, the WHO recently recommended that countries adopted PDMC in malaria-endemic areas. This thesis aimed to address remaining evidence gaps that policy-makers in sub-Saharan countries face when considering PDMC implementation. Namely, the determinants of caregivers’ adherence to PDMC in Malawi, the economic evaluation of different delivery strategies of PDMC in south-eastern African settings, and the value of further information for sub-Saharan Africa were, analysed. Data Sources: Data from an efficacy trial in Kenya and Uganda (n=1 040) and a delivery trial in Malawi (n = 375), conducted from 2016 to 2018, were used for the three analyses, and complemented with data from the literature. Both trials used three months with monthly dihydroartemisinin-piperaquine (DHAP) for PDMC. The efficacy trial compared PDMC to a placebo treatment. The delivery trial compared community-based PDMC delivery, where the full nine doses of DHAP were distributed to caregivers at hospital discharge, to facility-based PDMC delivery, where three monthly doses were collected monthly from the hospital. Methods: Modified Poisson regression analysis was used to predict caregiver adherence based on child, caregiver, and household features (predictor analysis, Paper 1). Results are reported as relative risk for high adherence. The cost-effectiveness analysis (CEA, Paper 2) used Markov decision models to compare the two delivery strategies of PDMC with the standard of care for Malawi, Kenya, and Uganda. A societal costing perspective was assumed and results are reported as incremental cost-effectiveness ratios per quality-adjusted life-year gained. In a value of information analysis (VOI, Paper 3), we calculated the per-decision net monetary benefit (NMB) for Kenya, Uganda, and Malawi, of perfect and partial perfect information for the input variables of the CEA. A scenario with halved adherence rates to simulate real-world implementation conditions was included. Results were reported as per country annual NMB of perfect information, and applied to 27 other sub-Saharan countries, adjusted for variations in purchasing power and willingness to pay thresholds. Results and Interpretation: No conclusive set of determinants for PDMC adherence could be found in the predictor study. A socio-economic index showed mixed associations across quintiles with poor adherence. Children with four or more malaria infections before admission were associated with reduced adherence. PDMC combines multiple factors that complicate adherence behaviour, and we suggest that established predictive factors for adherence to less complex regimens have weaker or more complex associations with adherence to PDMC. The CEA showed that PDMC was cost-saving and more effective than standard of care treatment. Community-based PDMC delivery was the cost-effective strategy in all countries, confirmed in sensitivity analyses. The robust results suggest that PDMC is cost-effective and that distributing a full course of PDMC at discharge is the optimal delivery strategy for malaria-endemic south-eastern African settings. The VOI analysis confirmed this result, identifying only two categories of model input with uncertainties that had a potential impact on the decision for the optimal delivery strategy: the relative mortality rate when receiving PDMC compared to standard of care, and the adherence rates. Perfect information on both parameters had a theoretical annual value of US1 379, 7979,and7 979, and 4 840 for Malawi, Kenya, and Uganda, respectively. The scenario with reduced adherence rates generated comparable, overall lower, values of perfect information. Larger research projects to resolve these uncertainties may, thus, not be economically justifiable.Doktorgradsavhandlin

    The use of African written tales as a didactic approach in the teaching of FLE in Cameroon: Case of written production and oral expression of learners

    No full text
    Revised version. Minor spelling and formatting errors corrected.With the introduction of national languages into the educational system in Cameroon by the Ministry of Secondary Education, we noticed increasing interest in the use of tales as a teaching corpus although this is still done in a timid manner. The aim of this research is to examine the poteintial impact of the use of African written tales on oral expression and the performance of written production of learners in Cameroon. In the theoretical framework, after having defined the tale and presented the typology of modern and African tales, as well as its characteristics, we explored the morphology of Vladimir Propp and Greimas actantial model, the elements of oral production according to Dubois A.L, the didactics advantages of tales according to Badenas Roig, S. R. and activities in the French as a foreign language class with story proposed by Trottet, S., & A mireault, V. Concerning the methodology, we used a mixed qualitative and quantitative research method. For qualitative research, we opted for questionnaires which were administered to 15 teachers and 123 learners from the central Cameroon region of public and private establishments. Quantitative research focuses on observation where we observed two classes, one of 32 students and the other of 28 students. At the end of our survey, learners and teachers find the introduction of stories in French as a foreign language lesson useful because according to them it improves their level of oral expression and performance of written production. if the tales are advantageous for the teaching/learning of French as a foreign language it would therefore be wise to review the French as a foreign language textbook for a total introduction of written African tales in the teaching of languages in Cameroon.Fransk mastergradsoppgaveFRAN350MAHF-LÆFRMAHF-FRA

    Deglasiasjonsperioden i Karmøyområdet: -datering av innsjøarkiver, implikasjoner for deglasiasjonskronologi og havnivåendringer

    Get PDF
    Målsetningen med denne studien er å forbedre den kronologiske forståelsen av isavsmeltingen i området rundt ytre Boknafjorden. Tre sedimentkjerner fra myren Liastemmen, på sørlige Karmøy, er analysert ved hjelp av tefrokronologi, korrelering av stratigrafi fra nærliggende lokaliteter, radiokarbondateringer og rekalibrering av tidligere havnivådata. Litostratigrafien deles inn i 4 enheter som representerer kronosonene eldre dryas, bølling-allerød, yngre dryas og holocen. Stratigrafien på Liastemmen er undersøkt for tefra, noe som ikke tidligere er dokumentert fra denne lokaliteten. Vedde-asken er observert på dybde 654-650 cm i kjerne 2-b2, sentralt i yngre dryas-laget, og identifiseres ved bruk av stereomikroskop. Annen tefra er ikke observert i stratigrafien. Tre radiokarbondateringer (¹⁴C) er utført for å utvikle en aldersmodell og tidfeste deglasiasjonen i området, som modelleres til en alder av 17,07 ± 0,72 k kal. BP. Resultatene sammenliknes med tidligere undersøkelser fra de nærliggende lokalitetene Grødheimsvatnet og Kringlemyr, som begge ligger under marin grense. For Grødheimsvatnet er det også utarbeidet en kurve for relativt havnivå fra deglasiasjonen (18k kal. BP) til nåtid. Radiokarbondateringene er rekalibrert med mål om å fastsette en mer presis aldersbestemmelse for deglasiasjonen i området rundt ytre Boknafjorden. Dette masterprosjektet inngår i et langvarig arbeid for å forstå havnivå og isavsmeltingshistorien i Nordsjøen og Vestlandet.Masteroppgave i geovitenskapGEOV399MAMN-GEO
