This article is open access.Introduction: Iceland is well suited for epidemiological research due to well-kept patient records, easy followup of patients and nation-wide health care databases. This study provides a nationwide 30-year epidemiological overview of the HIV epidemic in the country. Materials and methods: Retrospective study on all HIV positive individuals in Iceland, 1983-2012. Clinical data, CD4+ T-cell counts, plasma HIV RNA, proportion of late presenters and effectiveness of combined antiretroviral therapy (cART) were compared by different time intervals. Results: In total, 313 were diagnosed with HIV in 1983-2012, thereof 222 (71%) men and 91 (29%) women. Most infections (65%) were acquired outside the country. Mean incidence of HIV was 3.7/100,000 inhabitants/year, with a significant increase in 2010-2012 (p=0.0113), related to misuse of the prescription drug methylphenidate among intravenous drug users. Official prescriptions for this drug increased from 3.5 in 2002 to 17.4 defined daily doses/ 1,000 inhabitants/day in 2012. Mortality decreased by 70% during the study period (p=0.0275). Proportion of late presenters decreased from 74% in the first decade to 36% during the third (p=0.0001). After 6 months of ART, CD4+ T-cells increased by only 26 cells/µl on average during the monotherapy era (1987-1995; p=0,174), by 107 cells/µl during the early-cART era (1996-2004; p<0.0001) and by 159 cells/µl during the late-cART era (2005-2012; p<0,0001). Similarly, progressively greater reductions in plasma HIV RNA were observed from 1996-2004 to 2005-2012 (p<0.0001). Conclusions: HIV incidence remained relatively low in Iceland until 2010, when it increased significantly due to spread among IDUs. The majority of HIV infections diagnosed in Iceland were imported. With ever more effective drug treatments on CD4+ T-cells and plasma HIV RNA, the number of AIDS diagnoses and deaths has decreased dramatically.University of Iceland Research Fund, Gilead Nordic

Neðst á síðunni er hægt að nálgast greinina í heild sinni með því að smella á hlekkinn Skoða/Opna(view/open)INTRODUCTION: The prevelance of allery and asthma has increased rapidly over the last 3 decades and is now estimated that 25-30% of population in Western industrialized countries show symptoms of allergy or asthma. The aim of this study was to reveal the success of allergen immunotherapy (AIT) in Landspitali from 1977-2006. MATERIAL AND METHODS: During the study period a total number of 289 individuals underwent immunotherapy in outpatient clinic of allergy and asthma in Landspítali. A total number of 169 individuals were contacted, of whom 128 (76%) accepted to participate in the study. The evaluation was based on medical records, standardized questionnaire and skin-prick tests. RESULTS: Patients were evaluated on the average of 20 years after finishing treatment. 118 (92%) patients were desensitized to grass pollen, to birch pollen (30%), cat dander (30%) and dust mite (28%). At the time of the study 67% reported to be asymptomatic or with greatly improved allergy symptoms. Males had better response to AIT than women (p=0.04). Participants with positive family history of allergy and/or asthma in first degree relatives also reported better response to AIT (p=0.02). Furthermore, AIT to grass pollen and dust mite seemed to be more effective than AIT to cat dander and birch (p=0.04). AIT was also shown to reduce asthma. CONCLUSION: AIT for 3-5 years provides significant beneficial effect of allergy and asthma symptoms in patients who undergo such therapy. Finally, it s findings support the notion that AIT may reduce the risk of new allergic manifestations.Inngangur: Tíðni ofnæmis hefur farið ört vaxandi á síðastliðnum þremur áratugum og er nú talið að allt að 25-30% íbúa iðnríkjanna sýni einkenni ofnæmis í einhverri mynd. Tilgangur rannsóknarinnar var að varpa ljósi á árangur afnæmismeðferðar yfir 30 ára tímabil á Íslandi. Efniviður og aðferðir: Á rannsóknartímabilinu frá 1977 til 2006 hófu 289 einstaklingar afnæmismeðferð á göngudeild astma- og ofnæmissjúkdóma á Landspítalanum. Haft var samband við 169 manns og samþykktu 128 (76%) þátttöku í rannsókninni. Upplýsinga var aflað með stöðluðum spurningalista og aflestri sjúkraskráa. Sjúklingar voru að auki húðprófaðir. Niðurstöður:Að meðaltali voru 20 ár liðin frá lokum afnæmismeðferðar þegar árangur hennar var metinn í þessari rannsókn. Alls voru 118 (92%) einstaklingar afnæmdir gegn vallarfoxgrasi, 39 (30%) gegn birki, 38 (30%) gegn köttum og 36 (28%) gegn rykmaurum. Við endurmat sjúklinga reynust 86 (67%) vera einkennalausir eða betri. Karlmenn svöruðu að jafnaði meðferð betur en konur (p=0,04). Ættarsaga um ofnæmi eða astma í fyrstu gráðu ættingjum hafði jákvæð áhrif á árangur afnæmismeðferðar (p=0,02). Að auki var sýnt fram á að afnæmismeðferð gegn vallarfoxgrasi og rykmaurum skilaði betri árangri en afnæming gegn birki og köttum (p=0,04). Meðferðin dró úr líkum á astma síðar meir. Ályktanir:Afnæmismeðferð sem stendur yfir í 3-5 ár að meðaltali dregur almennt úr einkennum ofnæmissjúklinga til lengri tíma. Þá má leiða líkur að því að afnæmismeðferð minnki líkur á þróun nýs ofnæmis
Treatment as Prevention for Hepatitis C (TraP Hep C) - a nationwide elimination programme in Iceland using direct-acting antiviral agents
To access publisher's full text version of this article, please click on the hyperlink in Additional Links field or click on the hyperlink at the top of the page marked FilesA nationwide programme for the treatment of all patients infected with hepatitis C virus (HCV) was launched in Iceland in January 2016. By providing universal access to direct-acting antiviral agents to the entire patient population, the two key aims of the project were to (i) offer a cure to patients and thus reduce the long-term sequelae of chronic hepatitis C, and (ii) to reduce domestic incidence of HCV in the population by 80% prior to the WHO goal of HCV elimination by the year 2030. An important part of the programme is that vast majority of cases will be treated within 36 months from the launch of the project, during 2016-2018. Emphasis is placed on early case finding and treatment of patients at high risk for transmitting HCV, that is people who inject drugs (PWID), as well as patients with advanced liver disease. In addition to treatment scale-up, the project also entails intensification of harm reduction efforts, improved access to diagnostic tests, as well as educational campaigns to curtail spread, facilitate early detection and improve linkage to care. With these efforts, Iceland is anticipated to achieve the WHO hepatitis C elimination goals well before 2030. This article describes the background and organization of this project.

Er þörf á sérstakri heilbrigðismóttöku fyrir háskólanemendur?
Efst á síðunni er hægt að nálgast greinina í heild sinni með því að smella á hlekkinnTilgangur: Víða erlendis hafa háskólanemendur aðgang að heilbrigðisþjónustu sem er sérstaklega ætluð þeim. Tilgangur þessarar könnunar meðal nemenda við Háskóla Íslands var að skoða þörf þeirra fyrir sérstaka heilbrigðismóttöku. Aðferð: Rafræn könnun var lögð fyrir 9744 nemendur við háskólann vorið 2011 sem voru á póstlista. Spurningalistinn var saminn af vinnuhópi sem í voru fulltrúar frá öllum deildum Heilbrigðisvísindasviðs Háskóla Íslands. Stuðst var við lýsandi tölfræði við gagnagreiningu. Niðurstöður: Alls bárust svör frá 1487 þátttakendum, 1427 íslenskumælandi og 60 enskumælandi, og gefa svörin því mynd af viðhorfum 15,2% nemenda við skólann. Úrtakið endurspeglar einkum viðhorf kvenstúdenta og nema í grunnnámi. Tæplega 40% íslensku nemanna og um 70% þeirra erlendu höfðu ekki heimilislækni á höfuðborgarsvæðinu. Niðurstöður sýndu að meirihluti þeirra þurfti á heilbrigðisþjónustu að halda á árinu fyrir könnunina en rúmlega helmingur beið með að leita eftir heilbrigðisþjónustu og var meginástæða þess kostnaður. Um þriðjungur íslensku nemanna og fimmtungur þeirra erlendu sögðust eiga í fjárhagsvanda. Um 92% þeirra íslensku og allir erlendu nemarnir sögðust mundu leita á móttöku þar sem þjónustan væri veitt af nemendum skólans undir leiðsögn kennara. Báðir hóparnir vildu hafa aðgang að fjölbreyttri heilbrigðisþjónustu. Ályktanir: Niðurstöðurnar gefa til kynna að þeir háskólanemendur, sem þátt tóku í könnuninni, hafi mikla þörf fyrir sérstaka heilbrigðismóttöku. Kostnaður hefur hvað mest hindrað þá í að leita eftir heilbrigðisþjónustu. Jafnframt er stór hópur án heimilislæknis, einkum sá erlendi, og hefur því ekki greiðan aðgang að heilbrigðisþjónustu á heilsugæslustöðvum.Purpose: In many neighbouring countries university students have access to health services which are specially geared to their needs. The purpose of this survey among university students at the University of Iceland was to explore their need for a special health service. Method: The online survey was administered to 9744 students at the university in the spring of 2011 who were registered e-mail recipients, both Icelandic and English-speaking. The questionnaire was developed by a working group which consisted of representatives from all the faculties at the School of Health Sciences. Data were analysed by descriptive statistical methods. Results: There were 1487 participants who responded, 1427 Icelandic and 60 English-speaking representing 15,2% of the university student population. The sample represents especially the attitudes of undergraduate and female students. Almost 40% of the Icelandic students and nearly 70% of the English-speaking students did not have a family practitioner in the capital area. The results showed that the great majority of respondents had needed health services in the year before the study took place. More than half of them reported that they had postponed seeking health services citing cost as the main reason. About 92% of the Icelandic students and all of the foreign students reported that they would attend a health clinic which was provided by university students under supervision. Both groups would like to have access to various health care services. Conclusions: The results indicate that university students who answered the questionnaire had a great need for special health clinic. Costs of service had mainly prevented them from seeking health care services. Additionally, the proportion of students without a family practitioner is high, especially among the foreign students, which is a further hindrance regarding access to primary health care services.Heilbrigðisvísindasvið Landspítal

Balancing extensive ambition and a context overflowing with opportunities and demands: A grounded theory on stress and recovery among highly educated working young women entering male-dominated occupational areas
Several factors underline the issue of stress-related health among young highly educated women. Major societal changes might provide more new challenges with considerably changed and expanded roles than were expected by earlier generations, especially among women. The quantity of young women with higher education has also increased threefold in Sweden in less than two decades and there are a growing number of young women that hereby break with traditional gender positions and enter new occupational areas traditionally dominated by men. The research questions in the present study were: “What is the main concern, regarding stress and recovery, among young highly educated working women breaking with traditional gender positions and entering male-dominated occupational areas?” and “How do they handle this concern?” We conducted open-ended interviews with 20 informants, aged 23-29 years. The results showed that the synergy between highly ambitious individuals and a context overflowing with opportunities and demands ended up in the informants’ constantly striving to find a balance in daily life (main concern). This concern refers to the respondents experiencing a constant overload of ambiguity and that they easily became entangled in a loop of stress and dysfunctional coping behavior, threatening the balance between stress and sufficient recovery. In order to handle this concern, the respondents used different strategies in balancing extensive ambition and a context overflowing with opportunities and demands (core category). This preliminary theoretical model deepens our understanding of how the increasing numbers of highly educated young women face complex living conditions endangering their possibility of maintaining health and work ability
Wheat-barley hybridization – the last forty years
Abstract Several useful alien gene transfers have
been reported from related species into wheat (Triticum
aestivum), but very few publications have dealt
with the development of wheat/barley (Hordeum
vulgare) introgression lines. An overview is given
here of wheat 9 barley hybridization over the last
forty years, including the development of
wheat 9 barley hybrids, and of addition and translocation
lines with various barley cultivars. A short
summary is also given of the wheat 9 barley hybrids
produced with other Hordeum species. The meiotic
pairing behaviour of wheat 9 barley hybrids is presented,
with special regard to the detection of wheat–
barley homoeologous pairing using the molecular
cytogenetic technique GISH. The effect of in vitro
multiplication on the genome composition of intergeneric
hybrids is discussed, and the production and
characterization of the latest wheat/barley translocation
lines are presented. An overview of the agronomical
traits (b-glucan content, earliness, salt tolerance,
sprouting resistance, etc.) of the newly developed
introgression lines is given. The exploitation and
possible use of wheat/barley introgression lines for
the most up-to-date molecular genetic studies
(transcriptome analysis, sequencing of flow-sorted
chromosomes) are also discussed

Co-occurrence of diabetes and hopelessness predicts adverse prognosis following percutaneous coronary intervention
We examined the impact of co-occurring diabetes and hopelessness on 3-year prognosis in percutaneous coronary intervention patients. Consecutive patients (n = 534) treated with the paclitaxel-eluting stent completed a set of questionnaires at baseline and were followed up for 3-year adverse clinical events. The incidence of 3-year death/non-fatal myocardial infarction was 3.5% in patients with no risk factors (neither hopelessness nor diabetes), 8.2% in patients with diabetes, 11.2% in patients with high hopelessness, and 15.9% in patients with both factors (p = 0.001). Patients with hopelessness (HR: 3.28; 95% CI: 1.49-7.23) and co-occurring diabetes and hopelessness (HR: 4.89; 95% CI: 1.86-12.85) were at increased risk of 3-year adverse clinical events compared to patients with no risk factors, whereas patients with diabetes were at a clinically relevant but not statistically significant risk (HR: 2.40; 95% CI: 0.82-7.01). These results remained, adjusting for baseline characteristics an
