Discrimination amongst Arctic Indigenous Sámi and non-Sámi Populations in Norway

Background: Recent research demonstrates that for many indigenous Sami people, experiencing ethnic discrimination is a regular occurrence. The present study was designed to provide estimates of the prevalence of self-reported discrimination in order to identify specific settings where discrimination happened, to identify perpetrators and to examine individuals’ responses to the discrimination. Methods: In 2012, all inhabitants aged between 18 and 69 living in selected municipalities with both Sami and non-Sami settlements in mid- and northern Norway were mailed an invitation to participate in a questionnaire survey covering questions about discrimination (types of discrimination, settings where discrimination happened, and who the perpetrator was). Altogether, 11,600 participated (a response rate of 27 %). Results: In total, 2,496 (21.5 % of the sample) reported discrimination; of these, 29.8 % reported that discrimination happened during the past two years. Ethnic affiliation, age, education level, income and living area were all significantly associated with differences in the frequency of experiencing discrimination. Respondents with a strong Sami affiliation reported the highest levels of discrimination; in total, 50.8 % responded that they had been discriminated against, compared with 14.3 % of the non-Sami respondents (OR=6.16 CI:5.42–7.00). Sami with strong Sami affiliation reported having experienced significantly more discrimination over the past two years more than did the non-Sami respondents (16.5 % vs 4.4 % respectively; p \u3c 0.001; OR=4.15 CI:3.45–4.99). Additionally, Sami respondents reported experiencing discrimination in multiple settings more often than did nonSami respondents (p \u3c 0.001). Respondents aged between 30 and 49 years, those with a medium high level of education, those with medium household income, and those living in Sami minority areas, reported the highest prevalences of discrimination. In terms of responses to discrimination, 37.6 % reported that they had done something to stop the discrimination, and 19.1 % reported that the discrimination had affected them a lot. Just 1.8 % of those who reported having been discriminated against had been in contact with the Equality and Anti-Discrimination Ombudsman Service in Norway. Conclusion: The findings from this study show that the Sami people still experience high levels of discrimination in Norwegian society. Our findings suggest that interventions specifically designed to prevent discrimination against the indigenous Sami people of Norway should be implemented

Cancer among circumpolar populations : an emerging public health concern

Objectives. To determine and compare the incidence of cancer among the 8 Arctic States and their northern regions, with special focus on 3 cross-national indigenous groups - Inuit, Athabaskan Indians and Sami. Methods. Data were extracted from national and regional statistical agencies and cancer registries, with direct age-standardization of rates to the world standard population. For comparison, the "world average'' rates as reported in the GLOBOCAN database were used. Findings. Age-standardized incidence rates by cancer sites were computed for the 8 Arctic States and 20 of their northern regions, averaged over the decade 2000 - 2009. Cancer of the lung and colon/rectum in both sexes are the commonest in most populations. We combined the Inuit from Alaska, Northwest Territories, Nunavut and Greenland into a "Circumpolar Inuit'' group and tracked cancer trends over four 5-year periods from 1989 to 2008. There has been marked increase in lung, colorectal and female breast cancers, while cervical cancer has declined. Compared to the GLOBOCAN world average, Inuit are at extreme high risk for lung and colorectal cancer, and also certain rare cancers such as nasopharyngeal cancer. Athabaskans (from Alaska and Northwest Territories) share some similarities with the Inuit but they are at higher risk for prostate and breast cancer relative to the world average. Among the Sami, published data from 3 cohorts in Norway, Sweden and Finland show generally lower risk of cancer than non-Sami. Conclusions. Cancer among certain indigenous people in the Arctic is an increasing public health concern, especially lung and colorectal cancer.Peer reviewe

Modified prolonged exposure therapy as Early Intervention after Rape (The EIR-study): study protocol for a multicenter randomized add-on superiority trial

Background Sexual assault and rape are the traumatic life events with the highest probability for posttraumatic stress disorder (PTSD), which can have devastating consequences for those aficted by the condition. Studies indicate that modifed prolonged exposure (mPE) therapy may be efective in preventing the development of PTSD in recently traumatized individuals, and especially for people who have experienced sexual assault. If a brief, manualized early intervention can prevent or reduce post-traumatic symptoms in women who have recently experienced rape, healthcare services targeted for these populations (i.e., sexual assault centers, SACs) should consider implementing such interventions as part of routine care. Methods/design This is a multicenter randomized controlled add-on superiority trial that enrolls patients attending sexual assault centers within 72 h after rape or attempted rape. The objective is to assess whether mPE shortly after rape can prevent the development of post-traumatic stress symptoms. Patients will be randomized to either mPE plus treatment as usual (TAU) or TAU alone. The primary outcome is the development of post-traumatic stress symptoms 3 months after trauma. Secondary outcomes will be symptoms of depression, sleep difculties, pelvic foor hyperactivity, and sexual dysfunction. The frst 22 subjects will constitute an internal pilot trial to test acceptance of the intervention and feasibility of the assessment battery. Discussion This study will guide further research and clinical initiatives for implementing strategies for preventing post-traumatic stress symptoms after rape and provide new knowledge about which women may beneft the most from such initiatives and for revising existing treatment guidelines within this area

Different regression equations relate age to the incidence of Lauren types 1 and 2 stomach cancer in the SEER database: these equations are unaffected by sex or race

BACKGROUND: Although impacts upon gastric cancer incidence of race, age, sex, and Lauren type have been individually explored, neither their importance when evaluated together nor the presence or absence of interactions among them have not been fully described. METHODS: This study, derived from SEER (Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute) data, analyzed the incidences of gastric cancer between the years 1992–2001. There were 7882 patients who had developed gastric cancer. The total denominator population was 145,155, 669 persons (68,395,787 for 1992–1996, 78,759,882 for 1997–2001). Patients with multiple tumors were evaluated as per the default of the SEER*Stat program. 160 age-, five year period (1992–1996 vs 1997–2001)-, sex-, race (Asian vs non-Asian)-, Lauren type- specific incidences were derived to form the stratified sample evaluated by linear regression. (160 groups = 2 five year periods × 2 race groups × 2 sexes × 2 Lauren types × 10 age groups.) Linear regression was used to analyze the importance of each of these explanatory variables and to see if there were interactions among the explanatory variables. RESULTS: Race, sex, age group, and Lauren type were found to be important explanatory variables, as were interactions between Lauren type and each of the other important explanatory variables. In the final model, the contribution of each explanatory variable was highly statistically significant (t > 5, d.f. 151, P < 0.00001). The regression equation for Lauren type 1 had different coefficients for the explanatory variables Race, Sex, and Age, than did the regression equation for Lauren type 2. CONCLUSION: The change of the incidence of stomach cancer with respect to age for Lauren type 1 stomach cancer differs from that for Lauren type 2 stomach cancers. The relationships between age and Lauren type do not differ across gender or race. The results support the notion that Lauren type 1 and Lauren type 2 gastric cancers have different etiologies and different patterns of progression from pre-cancer to cancer. The results should be validated by evaluation of other databases

HIV Protein Sequence Hotspots for Crosstalk with Host Hub Proteins

HIV proteins target host hub proteins for transient binding interactions. The presence of viral proteins in the infected cell results in out-competition of host proteins in their interaction with hub proteins, drastically affecting cell physiology. Functional genomics and interactome datasets can be used to quantify the sequence hotspots on the HIV proteome mediating interactions with host hub proteins. In this study, we used the HIV and human interactome databases to identify HIV targeted host hub proteins and their host binding partners (H2). We developed a high throughput computational procedure utilizing motif discovery algorithms on sets of protein sequences, including sequences of HIV and H2 proteins. We identified as HIV sequence hotspots those linear motifs that are highly conserved on HIV sequences and at the same time have a statistically enriched presence on the sequences of H2 proteins. The HIV protein motifs discovered in this study are expressed by subsets of H2 host proteins potentially outcompeted by HIV proteins. A large subset of these motifs is involved in cleavage, nuclear localization, phosphorylation, and transcription factor binding events. Many such motifs are clustered on an HIV sequence in the form of hotspots. The sequential positions of these hotspots are consistent with the curated literature on phenotype altering residue mutations, as well as with existing binding site data. The hotspot map produced in this study is the first global portrayal of HIV motifs involved in altering the host protein network at highly connected hub nodes
