To study peculiar features of daily AP rhythm and profile in men with cardiovascular risk factors residing in the Far North.
The study included 115 servicemen divided into 3 groups (hypertensive disease (HD), hypertonic type neurocirculatory asthenia (NCA) and risk factor of cardiovascular diseases other than AH). HD was diagnosed based on multiple AP measurements and 24-hr monitoring.
HD was associated with elevated mean AP, load indices and AP variability All patients had pathological type of morning dynamics. Normal daily rhythm of systolic AP (SAP) was documented in 66.1% of the patients with HD and in 68% with cardiovascular risk factors without AH. Normal daily rhythm ofdiastolic AP (DAP) was recorded in 63.5% of the patients with HD and in 72% with cardiovascular risk factors without AH. In group 2, normal daily rhythms of SAP and DAP were found in 44 and 56% of the cases respectively.
Men residing in the Far North under conditions of anomalous photoperiod need medicamentous correction of AP regardless of AH type. Ambulatory BP monitoring should be preferred for the assessment of the efficacy of antihypertensive therapy.
OBJECTIVE: To explore the effect of acculturation attitudes and ethnic and national identity on behavior problems in arctic minority adolescents in northern Norway. METHOD: The Youth Self-Report, the Multigroup Ethnic Identity Measure, and acculturation strategies were completed by 581 indigenous Sami and 291 Kven high school students in 1994-1995, at age 15-18 years. Response rate was 85%. Behavior problems were in addition to ethnic/national identity and acculturation attitudes studied in relation to ethnicity, gender, age, socioeconomic status, parentage, ethnic language, and ethnic context. RESULTS: Although there were no ethnic group differences in behavior problems, the impact of ethnocultural predictors differed between ethnocultural and indigenous adolescents. Acculturation attitudes were most significant for indigenous adolescents' mental health, and identity issues showed the strongest impact on ethnocultural peers. The study revealed significant gender differences regarding the influence of ethnocultural factors, and contextual variation among Sami adolescents with the strongest impact in contexts with low density of Sami people. CONCLUSIONS: The significant ethnic group variations emphasize the importance of conducting both between- and within-group analysis on the impact of ethnocultural issues on behavior problems in minority adolescents.
Disorders of dietary sugar assimilation occur more often among native people of the Arctic then in temperate climate inhabitants.It is hypothesized that the limited variety of natural exogenous sugars in the Arctic, and their low content in the traditional diets of native northerners in accordance with a "protein-lipid" type of metabolism weakened selection, favoring diversity of disaccharidase enzymes.
Helicobacter pylori infection is an emerging health concern to some northern Canadian Aboriginal communities and their clinicians. Clinicians in the north perceive H. pylori infection to be a major clinical problem because they find H. pylori infection in many patients evaluated for common stomach complaints, leading to frequent demand for treatment, which often fails. Moreover, public health authorities identified the need for information to develop locally appropriate H. pylori control strategies. We described adherence and identified barriers to completing treatment among H. pylori-positive participants in a community-based project inspired by local concerns about H. pylori infection risks.
In 2008, 110 H. pylori-positive participants (diagnosed by a breath test, histopathology and/or culture) of the Aklavik H. pylori project were randomised to standard-of-care or sequential treatment. We ascertained adherence by interviewing participants using a structured questionnaire. We estimated adherence frequencies as the proportion of participants who reported taking either 100% of doses (perfect adherence) or =80% of doses (good adherence). To compare the proportion with perfect or good adherence in subgroups, we report proportion differences and 95% confidence intervals (CI).
Of 87 participants who were interviewed, 64% reported perfect adherence and 80% reported good adherence. We observed more frequent perfect adherence for: standard therapy (67%) versus sequential (62%); males (76%) versus females (52%); participants 40-77 years (79%) versus 17-39 (50%). Proportion differences were 5% (CI: -15, 25) for standard versus sequential therapy; 23% (CI: 4, 43) for male versus female; and 29% (CI: 10, 48) for 40-77 versus 15-39 years for perfect adherence. Of the 29 participants who reported poor adherence (
Forty-one newly sequenced isolates of Arctic and Arctic-like rabies viruses, were genetically compared to each other and to those available from GenBank. Four phylogenetic lineages of Arctic viruses were identified. Arctic-1 viruses circulate in Ontario, Arctic-2 viruses circulate in Siberia and Alaska, Arctic-3 viruses circulate circumpolarly, and a newly described lineage Arctic-4 circulates locally in Alaska. The oldest available isolates from Siberia (between 1950 and 1960) belong to the Arctic-2 and Arctic-3 lineages and share 98.6-99.2% N gene identity with contemporary viruses. Two lineages of Arctic-like viruses were identified in southern Asia and the Middle East (Arctic-like-1) and eastern Asia (Arctic-like-2). A time-scaled tree demonstrates that the time of the most recent common ancestor (TMRCA) of Arctic and Arctic-like viruses is dated between 1255 and 1786. Evolution of the Arctic viruses has occurred through a northerly spread. The Arctic-like-2 lineage diverged first, whereas Arctic viruses share a TMRCA with Arctic-like-1 viruses.

In Western Hemisphere arctic regions, scientific findings in humans, wildlife, and the environment have resulted in major governmental policy formulations. Government policy resulted in establishment of an effective international organization to address scientifically identified problems, including health disparities in arctic indigenous populations. Western scientific data and indigenous knowledge from initial international programs led to international agreements restricting certain persistent organic pollutants. In recent years, scientific data, and indigenous traditional knowledge, have resulted in governmental policy in the United States, Canada, and Nordic countries that includes the full participation of indigenous residents in defining research agendas, interpreting data, communicating information, and local community policy formulation.
