Humans obtain vitamin D from conversion of 7-dehydrocholesterol in the skin by ultraviolet B (UVB) radiation or from dietary sources. As the radiation level is insufficient in winter, vitamin D deficiency is common at higher latitudes. We assessed whether vernal solar UVB radiation at latitudes 61°N and 67°N in Finland has an impact on serum 25-hydroxyvitamin D [S-25(OH)D] concentrations. Twenty-seven healthy volunteers participated in outdoor activities in snow-covered terrain for 4-10 days in March or April, with their face and hands sun-exposed...

Frostbite sequelae are a relevant occupational injury outcome for soldiers in arctic environments. A Caucasian male soldier suffered frostbite to both hands during a military winter exercise. He developed sensory-motor disturbances and cold hypersensitivity. Angiography and thermography revealed impaired blood flow while Quantitative Sensory Testing indicated impaired somato-sensory nerve function. Two years after the initial event, he received an off label treatment with Botulinum toxin distributed around the neurovascular bundles of each finger...

BACKGROUND: Diabetes prevalence is substantially higher among Canadian First Nations populations than the non-First Nation population. Fasting serum triglycerides have been found to be an important predictor of incident diabetes among non-indigenous populations. However, there is a great need to understand diabetes progression within specific ethnic groups, particularly First Nations populations. OBJECTIVE: The purpose of this study was to test for an association between fasting serum triglycerides and incident diabetes, changes in insulin resistance and changes in β-cell function in a Manitoba First Nation cohort...

Monica C Skewes, Jordan P Lewis
Background Although notable health disparities related to alcohol use persist among Alaska Native people living in rural communities, there is a paucity of research examining drinking behaviour in particular segments of this population, including elders. One explanation for this is the distrust of behavioural health research in general and alcohol research in particular following the legacy of the Barrow Alcohol Study, still regarded as a notable example of ethics violations in cross-cultural research. Objective The present study reports findings from one of the first research studies asking directly about alcohol abuse among rural Alaska Natives (AN) since the study in Barrow took place in 1979...

Karen M Lawford, Audrey R Giles
The Kivalliq Inuit Centre (KIC), a boarding home in Winnipeg, Manitoba, is unique in its provision of a pilot prenatal education class and public health nursing services for Nunavummiut who are beneficiaries of the Nunavut Land Claim Agreement. Through a critical review of literature, policies and interviews related to evacuation for birth, we argue that the pilot at the KIC has the potential to play an important role in improving maternal child health for residents of Nunavut.
