Lung cancer is one of the most commonly diagnosed cancers in Canada and a leading cause of cancer mortality. Lung cancer also affects First Nations, Inuit and Métis peoples significantly in Canada, which deserves further investigation as there is a literature gap on this topic. We sought to develop a deeper understanding of lung cancer diagnosis, incidence, mortality, and survival in First Nations, Inuit, and Métis peoples in Canada. A systematic search was conducted in bibliographic databases to identify relevant studies published between January 2000 and March 2023. Articles were screened and assessed for relevance using the Population/ Concept/ Context (PCC) framework. A total of 22 articles were included in the final analysis, of which 13 were Inuit-specific, 7 were First Nations-specific, and 2 were Métis-specific. The literature suggests that comparative incidence, mortality, and relative risk of lung cancer is higher and survival is poorer in First Nations, Inuit and Métis peoples. Lung cancer also has varying impact on these population depending on sex, age, location and other factors. This review illustrates that more comprehensive quantitative and qualitative lung cancer research is essential to further identify the structural causes for the high incidence of the disease.

Traumatic spinal cord injury (TSCI) is a significant public health challenge that has an adverse impact on functional independence, quality of life, and life expectancy. Management of people’s chronic conditions is a key aspect of contemporary medical practice. Our study was an open label, single arm, prospective pilot study to evaluate the feasibility of treating people with TSCI. The study intervention was treatment with oral selenium and vitamin E. Participants were 18 years or older and experienced a TSCI at least one year prior to enrollment. Daily doses of 50 mcg of selenium and 400 IU of vitamin E were administered. Participants had radiologic (MRI tractography) and clinical (ASIA) assessments prior to initiating treatment, and these assessments were repeated after one year of treatment. Four subjects completed the full twelve-month study. Adherence, based on pill counts, was approximately 75% in all subjects. There were no adverse events related to study medications. During the treatment period, subjects reported improvement in certain symptoms. There was no significant difference in ASIA scores before and after the intervention. Combination treatment with vitamin E and selenium has been demonstrated as safe for TSCI patients. It is possible to use DTI values to locate the epicenter of a lesion as well as gauge the extent of injury. MRI tractography may serve as a meaningful surrogate endpoint. The results of this study suggest that it is feasible to conduct a larger long-term clinical trial to evaluate the efficacy of combination treatment of TSCI.
