VERDIEN AV LIV OG HELSE Hvor mye bør samfunnet være villig til å betale for helseforbedringer?

Økonomisk evaluering er et verktøy som har fått økende anvendelse som beslutningsgrunnlag ved prioriteringer i helsevesenet. Fordi det er knapphet på ressurser er det nødvendig å vurdere om nytten av ressursbruken eller ressursfordelingen står i et akseptabelt forhold til kostnadene. Det ville være uetisk å ignorere kostnaden ved en gitt helsetjeneste; det innebærer å ignorere spørsmålet om ressursbruken kunne gitt mer nytte i form av helseforbedring eller livredning for andre pasienter. Likevel reiser økonomiske analyser en rekke problemer av etisk, økonomisk-teoretisk, metodologisk og praktisk art. Senter for medisinsk metodevurdering (SMM), Helseøkonomiprogrammet ved Universitetet i Oslo (HERO) og Sosial- og helsedirektoratet (SHD) besluttet derfor våren 2002 å arrangere en konferanse der man ville drøfte noen av de vanskelige problemene knyttet til økonomisk evaluering og prioritering. Man inviterte politikere fra alle politiske fløyer og fagfolk med svært ulik tilnærming slik det fremgår av programmet. I denne rapporten legger vi frem skriftlige bidrag fra de fleste av foredragsholderne. En redaksjonskomite bestående av Berit Bringedal, Tor Iversen og Ivar Sønbø Kristiansen har redigert rapporten sammen med informasjonsmedarbeiderne Dagny Fredheim og Gunn Kristin Tjoflot. Redaksjonsarbeidet har begrenset seg til forslag om klargjøring av argumenter og enhetlig grafisk layout. Forfatterne har stått fritt til å uttrykke sine meninger, og disse står for enkeltpersonenes regning, ikke for deres arbeidsgiveres. Konferansen vakte stor interesse med ca 170 påmeldte deltakere. Mens mange av foredragsholderne hadde fått i oppdrag å vurdere grenser for samfunnets betalingsvilje for liv og helseforbedringer, ønsket de selv i liten grad å uttrykke seg konkret om dette. Artiklene belyser likevel en rekke teoretiske og praktiske aspekter ved økonomisk evaluering og prioritering. Rapporten gir et bilde av viktige helseøkonomiske problemstillinger, samt noen av de sentrale problemene knyttet til økonomiske analyser av helsetiltak. Vi håper rapporten kan være nyttig for alle som skal bruke økonomisk evaluering i sitt arbeide.Økonomisk evaluering; prioritering; helse

SARS-CoV-2 antibody prevalence among homeless people and shelter workers in Denmark:a nationwide cross-sectional study

BACKGROUND: People experiencing homelessness (PEH) and associated shelter workers may be at higher risk of infection with “Severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2). The aim of this study was to determine the prevalence of SARS-CoV-2 among PEH and shelter workers in Denmark. DESIGN AND METHODS: In November 2020, we conducted a nationwide cross-sectional seroprevalence study among PEH and shelter workers at 21 recruitment sites in Denmark. The assessment included a point-of-care test for antibodies against SARS-CoV-2, followed by a questionnaire. The seroprevalence was compared to that of geographically matched blood donors considered as a proxy for the background population, tested using a total Ig ELISA assay. RESULTS: We included 827 participants in the study, of whom 819 provided their SARS-CoV-2 antibody results. Of those, 628 were PEH (median age 50.8 (IQR 40.9–59.1) years, 35.5% female) and 191 were shelter workers (median age 46.6 (IQR 36.1–55.0) years and 74.5% female). The overall seroprevalence was 6.7% and was similar among PEH and shelter workers (6.8% vs 6.3%, p = 0.87); and 12.2% among all participants who engaged in sex work. The overall participant seroprevalence was significantly higher than that of the background population (2.9%, p < 0.001). When combining all participants who reported sex work or were recruited at designated safe havens, we found a significantly increased risk of seropositivity compared to other participants (OR 2.23, 95%CI 1.06–4.43, p = 0.02). Seropositive and seronegative participants reported a similar presence of at least one SARS-CoV-2 associated symptom (49% and 54%, respectively). INTERPRETATIONS: The prevalence of SARS-CoV-2 antibodies was more than twice as high among PEH and associated shelter workers, compared to the background population. These results could be taken into consideration when deciding in which phase PEH are eligible for a vaccine, as part of the Danish national SARS-CoV-2 vaccination program rollout.

A Prospective study of the association between weight changes and self-rated health

<p>Abstract</p> <p>Background</p> <p>Obesity and self-rated health (SRH) are strong predictors of morbidity and mortality but their interrelation is sparsely studied. The aim of this study was to analyse the association between weight changes and changes in SRH among women. We also examined if poor SRH at baseline was associated with later weight gain.</p> <p>Methods</p> <p>The Danish Nurse Cohort Study is a prospective population study (1993–1999) and comprises 13,684 female nurses aged 44 to 69 years. Logistic regression analyses were used to examine the association between weight changes and changes in SRH.</p> <p>Results</p> <p>Women who gained weight during the study period had higher odds of reporting poorer self-rated health (Odds Ratio (OR): 1.18, 95% CI: 1.04–1.35). Weight loss among overweight women, did not result in an increase in self-rated health ratings, in fully adjusted analyses (0.96 (95% CI: 0.76–1.23). Poor self-rated health combined with normal weight at first examination was associated with higher odds of later weight gain (OR: 1.29, 95% CI: 1.10–1.51).</p> <p>Conclusion</p> <p>Weight changes may result in lower SRH. Further, poor self-rated health at baseline seems to predict an increase in weight, among women without any longstanding chronic diseases. Future obesity prevention may focus on normal weight individuals with poor SRH.</p

Environmental factors in early childhood are associated with multiple sclerosis: a case-control study

<p>Abstract</p> <p>Background</p> <p>Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS) with increasing incidence mainly in high-income countries. One explanation of this phenomenon may be a higher prevalence of allergic and autoimmune diseases in industrialized countries as a consequence of otherwise beneficial advances in sanitation (hygiene hypothesis). We investigated environmental factors in early childhood associated with MS.</p> <p>Methods</p> <p>A case-control study was performed of 245 MS patients and 296 population-based controls in Berlin. The study participants completed a standardized questionnaire on environmental factors in childhood and youth, including aspects of personal and community hygiene. Multivariable logistic regression analysis was performed to investigate factors in childhood and youth associated with the occurrence of MS.</p> <p>Results</p> <p>Mean age was 46 years (range, 20-80) in the MS group and 42 years (range 18-80) in the control group, of which 73.9% in the MS and 61.5% in the control group were female. The multivariable analysis showed that having at least two older siblings (OR 0.54; p = 0.05, for individuals with two older siblings compared to individuals without older siblings), attending a day-care center (OR 0.5; p = 0.004) and growing up in an urban center with more than 100, 000 inhabitants (OR 0.43; p = 0.009) were factors independently associated with a lower chance for MS.</p> <p>Conclusions</p> <p>The hygiene hypothesis may play a role in the occurrence of MS and could explain disease distribution and increasing incidence.</p

Population genomics of the Viking world.

The maritime expansion of Scandinavian populations during the Viking Age (about AD 750-1050) was a far-flung transformation in world history1,2. Here we sequenced the genomes of 442 humans from archaeological sites across Europe and Greenland (to a median depth of about 1×) to understand the global influence of this expansion. We find the Viking period involved gene flow into Scandinavia from the south and east. We observe genetic structure within Scandinavia, with diversity hotspots in the south and restricted gene flow within Scandinavia. We find evidence for a major influx of Danish ancestry into England; a Swedish influx into the Baltic; and Norwegian influx into Ireland, Iceland and Greenland. Additionally, we see substantial ancestry from elsewhere in Europe entering Scandinavia during the Viking Age. Our ancient DNA analysis also revealed that a Viking expedition included close family members. By comparing with modern populations, we find that pigmentation-associated loci have undergone strong population differentiation during the past millennium, and trace positively selected loci-including the lactase-persistence allele of LCT and alleles of ANKA that are associated with the immune response-in detail. We conclude that the Viking diaspora was characterized by substantial transregional engagement: distinct populations influenced the genomic makeup of different regions of Europe, and Scandinavia experienced increased contact with the rest of the continent

Comprehensive genomic profiles of small cell lung cancer

We have sequenced the genomes of 110 small cell lung cancers (SCLC), one of the deadliest human cancers. In nearly all the tumours analysed we found bi-allelic inactivation of TP53 and RB1, sometimes by complex genomic rearrangements. Two tumours with wild-type RB1 had evidence of chromothripsis leading to overexpression of cyclin D1 (encoded by the CCND1 gene), revealing an alternative mechanism of Rb1 deregulation. Thus, loss of the tumour suppressors TP53 and RB1 is obligatory in SCLC. We discovered somatic genomic rearrangements of TP73 that create an oncogenic version of this gene, TP73Dex2/3. In rare cases, SCLC tumours exhibited kinase gene mutations, providing a possible therapeutic opportunity for individual patients. Finally, we observed inactivating mutations in NOTCH family genes in 25% of human SCLC. Accordingly, activation of Notch signalling in a pre-clinical SCLC mouse model strikingly reduced the number of tumours and extended the survival of the mutant mice. Furthermore, neuroendocrine gene expression was abrogated by Notch activity in SCLC cells. This first comprehensive study of somatic genome alterations in SCLC uncovers several key biological processes and identifies candidate therapeutic targets in this highly lethal form of cancer
