The health impacts of social distancing among Indigenous People in Ontario during the first wave of COVID-19

Among Indigenous People in Canada and around the world, the health impacts of COVID-19 have been measured largely through biological, social, and psychological impacts. Our study draws from a relational concept of health to examines two objectives: 1) how social distancing protocols have shaped Indigenous connections with self, family, wider community, and nature; and 2) to exploring what these changing relationships mean for perceptions of health. Carried out by an Indigenous team of scholars, community activists and students, this research draws from a decolonizing methodology and qualitative interviews (n=16) with Indigenous health and social care providers in urban and reserve settings. Our results illustrate a considerable decline in interpersonal connections, such as with family, community organizations, and larger social networks, as a result of social distancing. Among those already vulnerable, underlying health, social, and economic inequities have been exacerbated. While the health impacts of COVID-19 have been overwhelmingly negative, participants noted the importance of this time for self-reflection and reconnection of human-kind and with mother earth. This paper offers an alternative perspective to popularized views of Indigenous experiences of COVID-19 as they relate to vulnerability and resilience.

First Nations Food Environments: Exploring the Role of Place, Income, and Social Connection

BACKGROUND

In Canada, few studies have examined how place shapes Indigenous food environments, particularly among Indigenous people living in southern regions of Ontario.

OBJECTIVE

This paper examines and compares circumstances of food insecurity that impact food access and dietary quality between reserve-based and urban-based Indigenous peoples in southwestern Ontario.

METHODS

This study used a community-based survey containing a culturally adapted food-frequency questionnaire and cross-sectional study design to measure food insecurity, food access, and dietary quality among Indigenous respondents living in urban (n = 130) and reserve-based (n = 99) contexts in southwestern Ontario.

RESULTS

Rates of food insecurity are high in both geographies (55% and 35% among urban- and reserve-based respondents, respectively). Urban-based participants were 6 times more likely than those living on-reserve to report 3 different measures of food insecurity. Urban respondents reported income to be a significant barrier to food access, while for reserve-based respondents, time was the most pressing barrier. Compared with recommendations from Canada's Food Guide, our data revealed overwhelming trends of insufficient consumption in 3 food categories among all respondents. Close to half (54% and 52%) of the urban- and reserve-based samples reported that they eat traditional foods at least once a week, and respondents from both groups (76% of urban- and 52% of reserve-based respondents) expressed interest in consuming traditional foods more often.

CONCLUSIONS

Indigenous Food Sovereignty and community-led research are key pathways to acknowledge and remedy Indigenous food insecurity. Policies, social movements, and research agendas that aim to improve Indigenous food security must be governed and defined by Indigenous people themselves. Indigenous food environments constitute political, social, and cultural dimensions that are infinitely place based.

Exploring First Nation Elder Women's Relationships with Food from Social, Ecological, and Historical Perspectives

BACKGROUND

The ongoing negative health effects of colonization have disproportionately affected Indigenous women, who are disproportionately affected by diabetes, food insecurity, and undernutrition. Indigenous women also perceive their health less positively than men do. This article draws theoretically from the socio-ecological model to explore health inequalities experienced by Indigenous women associated with the intergenerational effects of the residential school legacy, specifically related to food practices.

OBJECTIVES

Study objectives were to describe and compare the historical context of present-day urban and rural food environments, and explore the hypothesis that food insecurity may be associated with cultural loss resulting from the intergenerational trauma of residential schools in this region of southwestern Ontario, Canada.

METHODS

Framed by a larger community-based participatory study, life history interviews took place with 18 Elder women living on- and off-reserve in southwestern Ontario, Canada.

RESULTS

Women discussed painful circumstances of displacement from the land and social disconnection from families and communities. The 10 participants who were residential school survivors conveyed the intergenerational effects of loss, responsibility, lack of support, and an altered sense of identity as narratives of survival. Six women had moved away from their home communities, which created challenges to fully engage in local food procurement and sharing practices. These altered geographies present practical limitations, along with apparent mechanisms of social and cultural exclusion.

CONCLUSIONS

Research on Indigenous Peoples' food systems requires further analysis of the root causes of disparities in the context of societal and gender relations. Food sovereignty has been the domain of women, who have led movements aimed at both social and environmental justice. Unraveling the historical, social, and environmental determinants of Indigenous food knowledge will support and guide community and policy recommendations, highlighting the ongoing effects of residential schooling and other indirect examples of environmental dispossession that have disproportionately affected Indigenous women.

Determining the sources of nutrient flux to water in headwater catchments: Examining the speciation balance to inform the targeting of mitigation measures

Diffuse water pollution from agriculture (DWPA) is a major environmental concern, with significant adverse impacts on both human and ecosystem health. However, without an appropriate understanding of the multiple factors impacting on water, mitigation measures cannot be targeted. Therefore, this paper addresses this gap in understanding, reporting the hydrochemical monitoring evidence collected from the UK Government's Demonstration Test Catchments (DTC) programme including contrasting chalk and clay/mudstone catchments. We use data collected at daily and sub-daily frequency over multiple sites to address: (1) How does the behaviour of the full range of nitrogen (N) species and phosphorus (P) fractions vary? (2) How do N species and P fractions vary inter- and intra-annually? (3) What do these data indicate about the primary pollution sources? And (4) which diffuse pollution mitigation measures are appropriate in our study landscapes? Key differences in the rates of flux of nutrients were identified, dependent on catchment characteristics. Full N speciation and P fractionation, together with dissolved organic carbon (DOC) enabled identification of the most likely contributing sources in each catchment. Nitrate (NO₃-N) was the dominant N fraction in the chalk whereas organic and particulate N comprised the majority of the load in the clay/mudstone catchments. Despite current legislation, orthophosphate (PO₄-P) was not found to be the dominant form of P in any of the catchments monitored. The chalk sub-catchments had the largest proportion of inorganic/dissolved organic P (DOP), accompanied by episodic delivery of particulate P (PP). Contrastingly, the clay/mudstone sub-catchments loads were dominated by PP and DOP. Thus, our results show that by monitoring both the inorganic and organic fractions a more complete picture of catchment nutrient fluxes can be determined, and sources of pollution pin-pointed. Ultimately, policy and management to bring nutrient impacts under control will only be successful if a multi-stressor approach is adopted.

A prospective observational study of the association between cabin and outside air temperature, and patient temperature gradient during helicopter transport in New South Wales

The prevalence of hypothermia in patients following helicopter transport varies widely. Low outside air temperature has been identified as a risk factor. Modern helicopters are insulated and have heating; therefore outside temperature may be unimportant if cabin heat is maintained. We sought to describe the association between outside air, cabin and patient temperature, and having the cabin temperature in the thermoneutral zone (18-36°C) in our helicopter-transported patients. We conducted a prospective observational study over one year. Patient temperature was measured on loading and engines off. Cabin and outside air temperature were recorded for the same time periods for each patient, as well as in-flight. Previously identified risk factors were recorded. Complete data was obtained for 133 patients. Patients' temperature increased by a median of 0.15°C (P=0.013). There was no association between outside air temperature or cabin temperature and patient temperature gradient. The best predictor of patient temperature on landing was patient temperature on loading (R2=0.86) and was not improved significantly when other risk factors were added (P=0.63). Thirty-five percent of patients were hypothermic on loading, including those transferred from district hospitals. No patient loaded normothermic became hypothermic when the cabin temperature was in the thermoneutral zone (P=0.04). A large proportion of patients in our sample were hypothermic at the referring hospital. The best predictor of patient temperature on landing is patient temperature on loading. This has implications for studies that fail to account for pre-flight temperature.

Gimiigiwemin: Putting Knowledge Translation Into Practice With Anishinaabe Communities

<p>In the Anishinaabemowen lagnuage, <em>Gimiigiwemin</em> is a concept that means, “we are exchanging gifts.” In the context of research, Indigenous communities often share their gifts with researchers by exposing them to local ways of knowing. Researchers can engage in exchanging gifts through sharing their skills and working towards producing research that meets community needs, such as supporting efforts to maintain health-sustaining relationships with traditional lands. <em>Environmental repossession</em> refers to the social, cultural, and political processes through which Indigenous Peoples are building resilience and reclaiming their traditional lands and ways of life. These processes are important because the health, ways of living, and knowledge systems of Indigenous Peoples all depend on access to traditional lands. This paper presents the results of a community-based participatory research study conducted in collaboration with Elders (<em>n </em>= 46) from two Anishinaabe communities on the north shore of Lake Superior (Ontario, Canada). This research employed locally relevant forms of integrated knowledge translation as a means of exchanging the gift of knowledge amongst all involved. This process culminated in a 2-day celebration wherein talking circles were used to explore Elders’ ideas about potential strategies for environmental repossession in their communities. Results from the talking circles pointed to four main strategies: (1) re-establishing the relationship between Elders and youth, (2) increasing time spent on traditional lands, (3) improving physical health, and (4) fostering community pride. This research emphasizes the strength of adopting culturally appropriate approaches to knowledge translation within studies aimed at supporting community aspirations of environmental repossession. </p>

High-sensitivity ring-down evanescent-wave sensing in fiber resonators

We report on optical-fiber cavity ring-down spectroscopy (CRDS) in the liquid phase using a laser emitting at telecommunication wavelengths. A fiber-ring cavity, comprising a short evanescent-wave coupler for radiation-matter interaction, is used as a sensor while its resonance modes are frequency locked to the laser. Exploiting the intrinsic sensitivity and noise immunity of the CRDS technique, we show that liquid absorption can be detected down to a level that is nearly a factor of 20 above the shot noise limit. We provide a thorough comparison between the experimental results and various noise contributions and address different expressions that can be used to calculate the shot noise equivalent absorbance. As a proof of principle, polyamine detection in aqueous solutions is carried out demonstrating a minimum detectable absorbance of 1.8×10(-7)  Hz(-1/2), which, to our knowledge, is the best sensitivity limit reported to date for evanescent-wave sensors.

Health disparities in Canada today: some evidence and a theoretical framework

This paper documents contemporary evidence on patterns of health disparities in Canada and suggests theoretical mechanisms that give rise to these patterns. The overall health of Canadians, as measured by life expectancy or mortality, has improved dramatically over the past 30 years and some disparities have diminished slightly (e.g., life expectancy by income group for men), while others have increased (e.g., diabetes for Aboriginal peoples). Arguably the most egregious health disparities in Canada are those existing between Aboriginals and the rest of the Canadian population. This paper focuses specifically on three social determinants and their effects on disparities in health; Aboriginal status, income, and place. Overall we take the approach that disparities in health could be alleviated by reducing inequities in the distribution of these determinants. We further argue that these social determinants are proxies for opportunities, resources and constraints; all of which influence health outcomes. We suggest that policies focus on reducing the social inequities that lead to health disparities in Canada, rather than focusing on the disparities in health alone. Since the social determinants described here have been found to influence an array of disease outcomes, tackling them, rather than their outcomes, may have a greater overall influence on the health of the population.

The political ecology of health: perceptions of environment, economy, health and well-being among ‘Namgis First Nation

Informed by Mayer's (Progr. Hum. Geogr 20 (1996) 441) political ecology of disease framework, this paper investigates First Nation's perceptions of the links between environment, economy and health and well-being. A case study of 'Namgis First Nation (Alert Bay, British Columbia, Canada) is used to explore the risks and benefits of salmon aquaculture for British Columbia's First Nations. Analysis of interview data (n = 23) indicates strong links between reduced access to environmental resources, marginal participation in the economy, and declining community health and well being. Results suggest that aquaculture development has further decreased the community's access to environmental resources, thereby restricting those economic, social, and cultural activities that determine good health and well-being for this community.

A REVISION OF PHOREIOBOTHRIUM (TETRAPHYLLIDEA: ONCHOBOTHRIIDAE) WITH DESCRIPTIONS OF FIVE NEW SPECIES

Five new species of Phoreiobothrium (Cestoda: Tetraphyllidea) are described from carcharhiniform sharks collected from a diversity of localities throughout the world. These are Phoreiobothrium perilocrocodilus n. sp. from Negaprion acutidens, Phoreiobothrium anticaporum n. sp. from Negaprion brevirostris, Phoreiobothrium lewinense n. sp. from Sphyrna lewini, Phoreiobothrium robertsoni n. sp. from Carcharhinus brachyurus, and Phoreiobothrium blissorum n. sp. from C. plumbeus, This brings the number of described species of Phoreiobothrium to 17. The new species from the lemon sharks, P. perilocrocodilus n. sp. and P. anticaporum n. sp., both possess more bothridial subloculi than do all species from hammerhead sharks, and fewer subloculi than do all species from sharks of Carcharhinus spp. Phoreiobothrium anticaporum n. sp. is unique among Phoreiobothrium species in that its genital pore is located in the extreme anterior portion of the proglottid. Phoreiobothrium lewinense n. sp. is unique in its possession of a combination of 8-11 subloculi and basal hook prongs that lack internal channels. Phoreiobothrium robertsoni n. sp. possesses 25-29 subloculi, triangular bothridia that flare posteriorly, and hooks that extend well beyond the middle of the bothridia. Phoreiobothrium blissorum n. sp. is most similar to Phoreiobothrium lasium in that it possesses rectangular bothridia with greater than 22 subloculi and long filitriches on its scolex. However, it differs from the latter species in that rather than articulating with one another, the bases of the medial and lateral hooks are widely separated; it also possesses 5-6 (vs.) 7-8 columns of testes. Phoreiobothrium lasium and Phoreiobothrium tiburonis are redescribed. The host associations of P. lasium are reevaluated and a neotype is designated for this species. The mature proglottid of P. tiburonis is described for the first time from voucher material collected from the type host and locality. These data suggest that the proglottid information provided in the original description, which was obtained from detached gravid proglottids, may have come from a tapeworm species other than P. tiburonis. All 7 species treated here in detail were examined with scanning electron microscopy; most were found to exhibit a microthrix pattern similar to that described previously for other members of the genus, e.g., Phoreiobothrium manirei. Bladelike spinitriches were present on the strobila, cephalic peduncle, and proximal bothridial surfaces, but were lacking from the distal bothridial surfaces. These spinitriches varied in length and density among species. Filitriches were present on all of these surfaces, but varied somewhat in length among species. Phoreiobothrium lewinense n. sp. is exceptional in that spinitriches were not seen on the proximal bothridial surfaces. A key to Phoreiobothrium species is provided. This work brings the number of carcharhinid shark species known to host this onchobothriid genus to 6, and the number of sphyrnid species to 5. Like many other onchobothriid tapeworms, species of Phoreiobothrium appear to exhibit oioxenous specificity for their hosts. Given this, and the fact that a total of 9 genera and 46 species of carcharhinid and sphyrnid sharks have yet to be examined for Phoreiobothrium, the diversity of the genus globally is likely to greatly exceed that described to date.
