This document analyzes differences in life expectancy between residents of Inuit Nunangat and other Canadians from 1989-2003. It finds that life expectancy is 7-12 years lower for Inuit men and 9-12 years lower for Inuit women. The main contributors to these differences are injuries and suicide for men, which account for 7.5 years, and chronic diseases like lung cancer and COPD for women, accounting for 4 years. The differences are concentrated in specific age groups and causes of death vary between sexes.

The document summarizes a study on the experiences of Aboriginal men and women in Canada who transitioned from suicidal crises to becoming socially active in their communities. It finds that (1) participants resolved tensions between individual and collective identities through an integrated self/community life-world. (2) Their community engagements and activism facilitated healing and mutually reinforced resilience. (3) Resolving tensions between healing and activism was key to avoiding assimilation and enhancing community resilience.

Social and Behaviour factor predicting healthy agingGiorgio De Gobbi
1) The document discusses the roles of socioeconomic status and physical activity in predicting healthy aging. It provides data on life expectancy, active life expectancy, and rates of mortality from various causes in different socioeconomic groups.
2) Lower socioeconomic status is associated with higher mortality rates and shorter life expectancies. Those with less education and in manual/lower income jobs had worse health outcomes.
3) Engaging in physical activity is linked to longer, disability-free life expectancy and lower risks of poor health. Childhood social factors also influence late-life physical function and risk of disability.

1) HIV/AIDS is still an exceptional epidemic due to its long duration over multiple waves, its significant contribution to the global disease burden, and the severe demographic and economic impacts it has had in sub-Saharan Africa.
2) Countries like Swaziland have been hit particularly hard, with HIV prevalence rates over 25% of adults, which has led to declining life expectancy and population growth rates.
3) The high cost of lifelong antiretroviral treatment presents a major challenge to healthcare systems, especially in low-income countries where health expenditures are already very low. More sustainable financing models are needed.
This document discusses non-communicable diseases (NCDs) and mental health in low and middle income countries. It provides context on a 2011 UN meeting on NCDs that did not include mental health. It outlines the large burden of chronic diseases globally in terms of mortality and disability-adjusted life years lost. The main causes of NCDs are identified as tobacco use, poor diet, physical inactivity, and harmful alcohol use. The document questions how best to respond to this growing problem and what must be done, focusing on the need for comprehensive, multi-sector strategies that intervene at both individual and societal levels.

Delirium: The Next Proposed “Never Event.” Is This Realistic?hospira2010
This document discusses delirium, which has been proposed as a "never event" by CMS. It summarizes evidence that delirium is common in ICU patients, associated with worse outcomes, and risk factors include older age, medications like benzodiazepines and opioids. Multicomponent protocols including monitoring, mobility, and reducing modifiable risk factors can help prevent delirium. Daily interruption of sedation with spontaneous breathing trials may help reduce duration of mechanical ventilation and ICU stay. Alternative sedatives like dexmedetomidine that are less likely to cause delirium should be considered over benzodiazepines when possible.
This document discusses bullying within Aboriginal communities. It notes that:
- Nearly all Aboriginal youth have experienced bullying or lateral violence from their peers. Lateral violence refers to bullying among one's own community or ethnic group.
- 95% of young Aboriginal people have witnessed lateral violence and bullying at home. 95% of bullying among Aboriginal people is directed at other Aboriginal people.
- Lateral violence stems from colonization and oppression and is a way for oppressed groups to internalize pain and direct it at their own community instead of confronting larger systems of power. It causes negative mental health impacts.
- Forms of lateral violence include verbal and nonverbal attacks, sabotage, and scapegoating.

Presentation at the HOUSING REALITIES FOR INUIT 2012 WORKSHOP, organized by Inuit Tuttarvingat of NAHO, February 16, 2012, Ottawa, Ontario.
This document summarizes a presentation on housing, health, and the ongoing crisis for Inuit in Canada. It notes that Inuit have significantly lower life expectancy and higher rates of infant mortality and respiratory diseases than other Canadians. Housing is often overcrowded and in need of repair. Research is needed to better understand the links between housing conditions and health impacts and to identify policies to address the ongoing housing crisis for Inuit in Canada.
This document discusses factors contributing to housing (in)security and homelessness in the Northwest Territories of Canada. It explores how the meaning of "home" is context-dependent and multidimensional for Indigenous communities, involving connections to land, family, community, and traditional way of life. The document presents stories from individuals experiencing homelessness and housing insecurity, and examines how northern housing and social policies can both help and hinder solutions.

This document summarizes a project to engage Inuit youth in tobacco use reduction through video stories about quitting smoking. [1] The National Aboriginal Health Organization and Inuit Tuttarvingat developed the Inuit Tobacco-free Network to share knowledge about tobacco use reduction. [2] They hired Inuit youth to film video testimonials from people in their communities who have quit or tried to quit smoking. [3] The videos were used in a classroom contest in Nunavut schools to encourage youth to think about the harms of smoking and consider quitting. The contest provided feedback on the videos and strategies to improve youth tobacco prevention efforts.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

2. Outline
Objective
• To measure the contributions of age groups and
causes of death to differences life expectancy
between residents of Inuit Nunangat and the rest of
Canada
Rationale
• Life expectancy for residents of Inuit Nunangat is
lower than for residents in the rest of Canada
Specific causes of death in certain age groups are thought to
contribute to this difference
November 24, 2009 2/19
4. Data sources
Deaths:
• Canadian Mortality Database
• Three 5-year periods:
Centred on census years 1991, 1996, 2001 (1989-2003)
• Census subdivision code for usual place of residence
Population (person-years)
• Multiplied by factor of five for each mid-period census
• Mid-year population counts from census
November 24, 2009 4/19
5. Methods
- Analytic techniques
Life expectancy
• Standard abridged life tables (Chiang adjusted)
Cause decomposition
• What cause-specific mortality differences contribute
to total differences in life expectancy?
Contribution of specific causes of death to the total years of
difference between life expectancies
• Arriaga (1989) method from discrete life tables
November 24, 2009 5/19
6. Methods
- Causes of death
Global Burden of Disease
• Causes of death aggregated in a way that underpins
human development rather than the body system
I – Communicable, maternal, perinatal, and nutritional
II – Noncommunicable diseases
III – Injuries
Attributable Causes of Death
• Mackenbach et al. 2008 NEJM.

16. Discussion
Life expectancy difference appears to be
increasing between Inuit Nunangat & Canada
Difference is related to specific causes of death
• Males – injury & suicide are major contributors
Injury and suicide account for 7.5 years of difference
• Females – chronic diseases are major contributors
Lung cancer and COPD account for 4 years of difference
Specific causes differ between sexes
• Smoking-related diseases for females
• Alcohol-related diseases are not major contributors
November 24, 2009 16/19
17. Discussion
Difference is concentrated in specific age groups
• Males – mortality between 15 and 29 is key
1/3 of difference due to mortality between 15 and 29 years
This is largely due to injury and suicide
• Females – mortality after age 60 contributes most
50% of difference due to mortality after 60 years of age
This is largely due to chronic diseases

18. Limitations
Limits to geographic approach
• For all residents of Inuit Nunangat, not just Inuit
• Unequal access to health services
• Older population may move “south” for care
Reliability of vital statistics
• Cause of death coding may vary between periods
Use of a comparable population
• Comparison to other isolated communities, other
Aboriginal groups, or other countries
