Description of spatiotemporal patterns of infectious salmon anemia virus (ISAV) detections in marine Atlantic Salmon farms in Newfoundland and Labrador

OBJECTIVE

The objectives of this study were to describe spatiotemporal patterns of infectious salmon anemia virus (ISAV) detections in marine salmonid production sites in the province of Newfoundland and Labrador in Canada.

METHODS

Infectious salmon anemia virus surveillance data between 2012 and 2020 from the province of Newfoundland and Labrador were used. Data comprised a total of 94 sampling events from 20 Atlantic Salmon Salmo salar production sites in which ISAV was detected. Using linear regression models, factors influencing time to detection (days from stocking to first ISAV detection) and time to depopulation (days from first detection to production site depopulation) were investigated.

RESULT

Based on 28 unique cases, site-level annual incidence risk of ISAV detection ranged from 3% to 29%. The proportion of ISAV detection by PCR in fish samples ranged from 2% to 45% annually. Overall, ISAV variants from the European clade were more common than variants from the North American clade. The type of ISAV clade, detections of ISAV in nearest production sites based on seaway distances, and year of infectious salmon anemia cases were not associated with time to first ISAV detection. Time to depopulation for sites infected with the ISAV-HPRΔ variant was not associated with ISAV North American or European clades.

CONCLUSION

Our results contribute to the further understanding of the changing dynamics of infectious salmon anemia detections in Newfoundland and Labrador since its first detection in 2012 and will likely assist in the design of improved disease surveillance and control programs in the province.

Retrospective review of rates of sexually transmitted and blood-borne infection (STBBI) testing in provincial corrections facilities in Newfoundland and Labrador

Background

Sexually transmitted and blood borne infection (STBBI) testing is recommended for people who are incarcerated (PWAI). We sought to determine the rate of STBBI testing during admissions to provincial correctional institutions in Newfoundland and Labrador (NL).

Methods

This retrospective cohort study collected the identification of all admissions records in provincial correctional facilities in NL between July 1, 2020 and June 31, 2021 using the Provincial Corrections Offender Maintenance System database. Admissions to provincial detention centers were excluded. Records were linked with STBBI results, when available, within the electronic medical record (Meditech) using demographics. Testing rates, STBBI positivity rates, and univariate analysis of predictors for STBBI testing were completed.

Results

Of the 1,824 admissions identified, 1,716 were available for linkage to laboratory results. Admissions to detention centers (n = 105) were excluded. Any STBBI test result was available for 72 (4.5%) of admissions. No admission had complete testing for all STBBI. Facility testing rates ranged from 1.9 to 11.2% and 37.5% of STBBI tests had any positive results. Sixteen out of the 21 (76.2%) hepatitis C virus (HCV) antibody positives received HCV RNA testing, and 11/16 (88.8%) were HCV RNA positive. Institution (p = 0.001) and sex (p = 0.004) were found to be significant predictors of STBBI testing, while age was not significant (p = 0.496).

Conclusions

STBBI testing rates were low in provincial correctional facilities in NL, and STBBI prevalence, especially for HCV, was high among those tested. Strategies to increase the rate of testing could contribute to STBBI control in corrections facilities.

Results of a mixed-methods study on barriers to physician recruitment in Newfoundland and Labrador

Background

Like many rural and remote parts of Canada, the province of Newfoundland and Labrador (NL) struggles to maintain a skilled healthcare workforce. As many as 20% of people in the province are thought to be without a primary care physician. The purpose of this study was to determine the barriers recent Memorial University of Newfoundland medical alumni have faced in establishing medical practice in NL.

Methods

An online survey followed by question-standardised focus group sessions.

Results

Two hundred and ninety-one physicians who graduated from Memorial University of Newfoundland medical school between the years of 2003 and 2018 completed the survey. Nearly 80% of respondents recalled that NL was their preferred practice location at some point during training: 79.4% (n = 231) at the beginning of medical school and 77.7% (n = 226) at the beginning of residency training. However, at the time of the survey, only 160 (55.0%) respondents were working in NL. Respondents reported significant cultural and systemic barriers in trying to work in NL, including ineffective recruitment offices, lack of transparency in communication with health authorities, inequitable distribution of resources and workloads, lack of appropriate resources to support new positions, and return-of-service agreements that are not honoured or followed-up.

Conclusion

Our study outlines a number of ways in which recruitment and retention could be improved, ultimately improving provincial health care and helping to fulfil the mandate of the medical school.

Extensive SARS-CoV-2 testing reveals BA.1/BA.2 asymptomatic rates and underreporting in school children

Background

Case underreporting during the coronavirus disease 2019 (COVID-19) pandemic has been a major challenge to the planning and evaluation of public health responses. School children were often considered a less vulnerable population and underreporting rates may have been particularly high. In January 2022, the Canadian province of Newfoundland and Labrador (NL) was experiencing an Omicron variant outbreak (BA.1/BA.2 subvariants) and public health officials recommended that all returning students complete two rapid antigen tests (RATs) to be performed three days apart.

Methods

To estimate the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we asked parents and guardians to report the results of the RATs completed by K-12 students (approximately 59,000 students) using an online survey.

Results

When comparing the survey responses with the number of cases and tests reported by the NL testing system, we found that one out of every 4.3 (95% CI, 3.1-5.3) positive households were captured by provincial case count, with 5.1% positivity estimated from the RAT results and 1.2% positivity reported by the provincial testing system. Of positive test results, 62.9% (95% CI, 44.3-83.0) were reported for elementary school students, and the remaining 37.1% (95% CI, 22.7-52.9) were reported for junior high and high school students. Asymptomatic infections were 59.8% of the positive cases. Given the low survey participation rate (3.5%), our results may suffer from sample selection biases and should be interpreted with caution.

Conclusion

The underreporting ratio is consistent with ratios calculated from serology data and provides insights into infection prevalence and asymptomatic infections in school children; a currently understudied population.

Public Interest Group on Cancer Research: a successful patient-researcher partnership in Newfoundland and Labrador

BACKGROUND

Partnering with patients and family members affected by cancer is essential for meaningful research, public engagement and outreach, and advocacy activities.

OBJECTIVE

Our objective was to create a public interest group through an academic-community partnership focused on cancer research and public engagement.

METHODS

A purposeful recruitment process was implemented to ensure a diverse and inclusive group. The group meets virtually and communicates by email. The group's activities focus on identifying the needs, priorities, and interests of cancer-affected individuals in the province; consultations; and designing research projects and public outreach activities together. Comprehensive meeting minutes are kept and used to distill discussion points. The work of the group is disseminated through a variety of channels.

RESULTS

The public interest group includes 12 cancer patient and family member representatives, in addition to researchers. Discussions by the interest group identified key themes related to: (1) equity issues and regional disparity in provincial oncocare; (2) information needs; (3) need for patient empowerment and public understanding; and (4) family member and partner needs and experiences. To date, the group has co-designed a cancer research proposal and a public engagement/outreach activity. The group also provides consultations on cancer-related projects/public engagement activities and members act as patient partners in specific research and public engagement proposals. The group evolves over time, and increasingly advocates on behalf of cancer patients and families. Retention and satisfaction of the public partners with group activities have been high. The group's work and findings are disseminated to the Provincial Cancer Care Program, as well as to public and scientific stakeholders through local media, academic conferences and presentations, and a dedicated website.

CONCLUSION

Public Interest Group on Cancer Research represents a highly successful patient-researcher partnership in oncology. It designs meaningful and patient-oriented studies and outreach activities in cancer. It also elevates and widely supports cancer patient and family voice.

Laying the foundation for Real-world evidence studies: a case study from Newfoundland and Labrador

The Janssen and Newfoundland and Labrador Health Innovation Partnership (JANL-HIP) was established to carry out Real-World Evidence (RWE) projects to generate evidence about disease pathways, healthcare delivery, the effects of clinical interventions. Doing so will support and influence clinical decision-making in Newfoundland and Labrador (NL). This case study describes the foundational elements necessary for a real-world evidence generation project in NL and may provide learning for the effective execution of real-world studies in other jurisdictions. It uses an ongoing project in psoriatic disease in NL to illustrate the partnership and the benefits of RWE studies. Ultimately, the JANL-HIP RWE project aims to inform decisions that will drive improvements in health outcomes, system delivery, and policy mutually beneficial to health ecosystem stakeholders.

Sex differences in suicide mortality in Newfoundland and Labrador: An observational study with medical examiner data from 1997 to 2016

BACKGROUND

Globally, the suicide rate is two times higher for males than for females. Previous studies in Newfoundland and Labrador did not examine age-specific rates by sex. The objectives of this study were to determine suicide rates by sex and age group and to compare the demographic and clinical characteristics of males and females who died by suicide.

DATA AND METHODS

This observational study analyzed a routinely collected dataset based on all medical examiner-determined suicide deaths among people aged 10 years and older in Newfoundland and Labrador, Canada, between 1997 and 2016. Age-standardized and age-specific suicide rates and rate ratios were calculated based on the number of deaths during the period, and descriptive statistics were used to compare demographic and clinical characteristics between males and females.

RESULTS

The age-standardized suicide rate was 4.6 times higher among males than females and was higher for males in most age groups. Rates were highest in the young adult age groups for males (20 to 24 years) and females (35 to 39 years). Males who died by suicide were more likely to be from a rural community and to have died by firearm; females were more likely to die by self-poisoning and to have had a mental illness or substance use history.

INTERPRETATION

The results are broadly consistent with previous research, though this is the first study to report age-specific suicide rates among females across the life course in Newfoundland and Labrador. The results underscore the need to design public health and clinical interventions that account for sex differences in suicide risks.

Quantification and characterization of plastics in near-shore surface waters of Atlantic Canada

Plastics are a ubiquitous pollutant in the marine environment. Despite growing concerns, quantitative and qualitative data on microplastics in aquatic and marine environments of Atlantic Canada is just emerging. Surface water plastics were measured and categorized by morphology (thread, microfibre, fragment, foam, film, pellet, and microbead) in two locations in Nova Scotia and one in Newfoundland and Labrador, Canada. All sites within the three locations contained plastic with an average abundance of 9669 items/km². Most plastics (68 %) were sized as microplastics (0.425-5 mm), and plastic fragments were the most common morphological type. Polyethylene accounted for a third (30 %) of all particles found across all three locations, followed by polypropylene (23 %). Results can inform future research for community-based environmental groups, government, and academia.

A comparison of household food insecurity rates in Newfoundland and Labrador in 2011-2012 and 2017-2018

OBJECTIVES

The prevalence of household food insecurity in Newfoundland and Labrador (NL) fell sharply between 2007 and 2011, but it appears to have risen since then. Our objective was to compare the prevalence of food insecurity between 2011-2012 and 2017-2018 in relation to population socio-demographic characteristics.

METHODS

Our analytic sample comprised all NL households in the Canadian Community Health Survey (CCHS) cycles 2011-2012 and 2017-2018, n = 6800. We stratified the prevalence of household food insecurity for each cycle by socio-demographic characteristics and applied multivariable logistic regression models to determine food insecurity odds in 2017-2018 compared with 2011-2012 after controlling for socio-demographic covariates. Interactions of covariates with survey cycle were tested and models stratified when warranted.

RESULTS

The prevalence of food insecurity rose from 12.0% (95% CI 10.5, 13.6) in 2011-2012 to 14.7% (95% CI 13.1, 16.6) in 2017-2018. After adjusting for household socio-demographic variables, the odds of food insecurity was 1.49 (95% CI 1.27, 1.75) in 2017-2018. The prevalence of food insecurity had increased significantly among unattached individuals, renters, households with low educational attainment, and households with income above the Low Income Measure, with concomitant increases in the contribution of these groups to the total provincial prevalence of food insecurity in 2017-2018 compared with that in 2011-2012.

CONCLUSION

The odds of food insecurity among NL households increased significantly from 2011-2012 to 2017-2018. Given the serious negative health implications of household food insecurity, the province should draw on the lessons from its earlier success in food insecurity reduction to reverse the current trend.

The Incidence of Cutaneous Malignant Melanoma in Eastern Newfoundland and Labrador, Canada, from 2007 to 2015

BACKGROUND

The incidence of cutaneous malignant melanoma continues to increase worldwide and in Canada. It is unclear whether the increase in incidence and clinical characteristic trends of cutaneous malignant melanoma are similar in the province of Newfoundland and Labrador.

OBJECTIVE

The objective of this study is to examine the incidence and trends of cutaneous malignant melanoma in Eastern Newfoundland and Labrador.

METHODS

Patients aged 18 years or older diagnosed with cutaneous malignant melanoma were identified from the Eastern Health Authority's Cancer Registry. The diagnosis was confirmed by a pathologist via histological subtype. Patients were excluded if the diagnosis was unspecified, a nonmelanoma skin cancer or if there was a recurrence in the same lesion location. In total 298 patients diagnosed with cutaneous malignant melanoma from 2007 to 2015 were included in the analysis.

RESULTS

The total incidence increased from 4.1 to 15.6 cases/100,000 person-years, which represents a 283.0% increase from 2007 to 2015. The largest increases in incidence were seen in males and patients aged from 60 to 79 years. The most common lesion anatomical locations were the trunk in males and the lower extremity in females. The majority of cases had a Breslow thickness below 1.0 mm.

CONCLUSION

The incidence of cutaneous malignant melanoma in Eastern Newfoundland and Labrador is increasing at a faster rate than in any other region in Canada. Health care providers should work to be aware of the clinical trends and risk factors associated with this disease to facilitate early detection and prevent morbidity.

Labrador Emergencies and St. Anthony Institutional Care: Medical Cases of Donald McI. Johnson for the Grenfell Association, 1928-29

In contemporaneous and retrospective publications, British physician Donald McI. Johnson wrote about medical cases in 1928-29 for the organization founded by Wilfred Grenfell in Newfoundland and Labrador. The availability of one physician's cases in published and institutional forms allows consideration of discursive representations of patients for general and clinical readers in the two decades of Johnson's writing. This study places these cases within the context of Johnson's medical background and his escape to rural practice in a remote locale, one that emphasized emergency operations in Labrador and hospital care in the organization's main hospital in St. Anthony. In this way, it broadens knowledge of medical care provided by visiting physicians and considers ways in which such physicians represented local patients in publications for the general reader. Although it determines that Johnson was unique, it indicates the value of the fuller study of publications by other physicians associated with the Grenfell organization.

Publishing and Paternalism in the Grenfell Mission: Wilfred Grenfell's Accounts of a Boy Patient and Doctor-Patient Relations in Northern Newfoundland and Labrador, 1900-14

In 1906 Dr. Wilfred Grenfell, founder and head of the Grenfell medical mission of northern Newfoundland and southeastern Labrador, published a short article in Putnam's Monthly about a nine-year-old boy named Clem Richards, who had shot himself in the knee while hunting seabirds. The boy's identity was disclosed in full, with Grenfell including his name and image as well as a detailed description of his living conditions. The "story" of the boy's injury and recovery became a favourite of Grenfell's, and it was modified and republished in a number of magazines and books between 1906 and 1923. This article explores the appeal that Richards' accident held for Grenfell and argues that his dramatic mid-winter rescue of the boy helped Grenfell promote his mission and construct a public image of himself that would appeal to American readers and donors. By comparing published accounts with Richards' medical case record, however, we also see how much Grenfell distorted the incident to heighten its drama and reader appeal. The article also considers how the mission's dominance over northern Newfoundland and southeastern Labrador enabled Grenfell to use Richards' name and image for mission publicity with no consideration of patient consent.

"If We Can Make a Cure of Him": Lyrical Grenfell in the St. Anthony Casebooks, 1906

Narrative-based physician records contain much more than observerless data and diagnoses. Indeed, a "case," the basic currency of medical communication, can be seen as a literary genre, much like a novel or a poem, and given close readings for author voice, tradition, and influences. In this article, I describe my initial encounter with Dr. Wilfred Grenfell's casebooks in a hospital basement in St. Anthony, Newfoundland and Labrador, and my subsequent engagement with them as both a physician and a poet. Adopting Bleakley and Marshall's definition of medical lyricism as the impulse that "draws our attention to delicacy, tenderness and the joyous, and to verve, desire, eroticism, the fecund, abundance and generation," I argue that Grenfell's approach to medicine in early 20^th-century Newfoundland and Labrador was both a product of his scientific training and his enculturation at the end of the Victorian period.

Introduction-Case by Case: Private and Public Representations of Patients in the Grenfell Mission in Newfoundland and Labrador in the Early 20th Century

This article provides context for three studies about early 20^th-century medical cases in the geographically distributed humanitarian aid organization founded by Wilfred Grenfell in pre-Confederation Newfoundland and Labrador. It situates these studies within historiographical and theoretical approaches to case histories and their publication by medical practitioners, the background for research on the clinical records of the Grenfell organization's main hospital, and the history behind specific case information for coastal patients. While the cases examined cohere through their organizational origin, the authors of these three studies reveal sometimes unexpected representations of the patient in text and illustration. In these ways, both this introductory article and the following three studies emphasize the enduring appeal of narrative approaches to case writing while also pointing to the evolving ethics of publishing medical reports for general readers and scholars. Together they invite renewed attention to the representation of medical cases in publications that increasingly are available globally in internet collections.

Suicide in Newfoundland and Labrador, Canada: a time trend analysis from 1981 to 2018

BACKGROUND

The suicide rate in Canada decreased by 24% during the past four decades. However, rates vary between provinces and territories, and not all jurisdictions experienced the same changes. This study examined suicide rates over time in the province of Newfoundland and Labrador.

METHODS

We used cross-sectional surveillance data from the Canadian Vital Statistics Death Database to examine suicide rates in Newfoundland and Labrador from 1981 to 2018. We calculated annual age-standardized suicide mortality rates and used joinpoint regression to estimate the average annual percent change (AAPC) in suicide rates overall and by sex, age group, and means of suicide.

RESULTS

From 1981 to 2018, 1759 deaths by suicide were recorded among people in Newfoundland and Labrador. The age-standardized suicide mortality rate increased more than threefold over the study period, from 4.6 to 15.4 deaths per 100,000. The suicide rate was higher among males than females, and accounted for 83.1% of suicide deaths (n = 1462); the male-to-female ratio of suicide deaths was 4.9 to 1. The average annual percent change in suicide rates was higher among females than males (6.3% versus 2.0%). Age-specific suicide rates increased significantly for all age groups, except seniors (aged 65 or older); the largest increase was among youth aged 10 to 24 years old (AAPC 3.5; 95% CI, 1.6 to 5.5). The predominant means of suicide was hanging/strangulation/suffocation, which accounted for 43.8% of all deaths by suicide.

CONCLUSIONS

The suicide rate in Newfoundland and Labrador increased steadily between 1981 and 2018, which was in contrast to the national rate decline. The disparity between the provincial and national suicide rates and the variations by sex and age underscore the need for a public health approach to prevention that accounts for geographic and demographic differences in the epidemiology of suicide.

Modelling the impact of travel restrictions on COVID-19 cases in Newfoundland and Labrador

In many jurisdictions, public health authorities have implemented travel restrictions to reduce coronavirus disease 2019 (COVID-19) spread. Policies that restrict travel within countries have been implemented, but the impact of these restrictions is not well known. On 4 May 2020, Newfoundland and Labrador (NL) implemented travel restrictions such that non-residents required exemptions to enter the province. We fit a stochastic epidemic model to data describing the number of active COVID-19 cases in NL from 14 March to 26 June. We predicted possible outbreaks over nine weeks, with and without the travel restrictions, and for contact rates 40-70% of pre-pandemic levels. Our results suggest that the travel restrictions reduced the mean number of clinical COVID-19 cases in NL by 92%. Furthermore, without the travel restrictions there is a substantial risk of very large outbreaks. Using epidemic modelling, we show how the NL COVID-19 outbreak could have unfolded had the travel restrictions not been implemented. Both physical distancing and travel restrictions affect the local dynamics of the epidemic. Our modelling shows that the travel restrictions are a plausible reason for the few reported COVID-19 cases in NL after 4 May.

SARS-CoV-2 Surveillance System in Canada: Longitudinal Trend Analysis

BACKGROUND

The COVID-19 global pandemic has disrupted structures and communities across the globe. Numerous regions of the world have had varying responses in their attempts to contain the spread of the virus. Factors such as public health policies, governance, and sociopolitical climate have led to differential levels of success at controlling the spread of SARS-CoV-2. Ultimately, a more advanced surveillance metric for COVID-19 transmission is necessary to help government systems and national leaders understand which responses have been effective and gauge where outbreaks occur.

OBJECTIVE

The goal of this study is to provide advanced COVID-19 surveillance metrics for Canada at the country, province, and territory level that account for shifts in the pandemic including speed, acceleration, jerk, and persistence. Enhanced surveillance identifies risks for explosive growth and regions that have controlled outbreaks successfully.

METHODS

Using a longitudinal trend analysis study design, we extracted 62 days of COVID-19 data from Canadian public health registries for 13 provinces and territories. We used an empirical difference equation to measure the daily number of cases in Canada as a function of the prior number of cases, the level of testing, and weekly shift variables based on a dynamic panel model that was estimated using the generalized method of moments approach by implementing the Arellano-Bond estimator in R.

RESULTS

We compare the week of February 7-13, 2021, with the week of February 14-20, 2021. Canada, as a whole, had a decrease in speed from 8.4 daily new cases per 100,000 population to 7.5 daily new cases per 100,000 population. The persistence of new cases during the week of February 14-20 reported 7.5 cases that are a result of COVID-19 transmissions 7 days earlier. The two most populous provinces of Ontario and Quebec both experienced decreases in speed from 7.9 and 11.5 daily new cases per 100,000 population for the week of February 7-13 to speeds of 6.9 and 9.3 for the week of February 14-20, respectively. Nunavut experienced a significant increase in speed during this time, from 3.3 daily new cases per 100,000 population to 10.9 daily new cases per 100,000 population.

CONCLUSIONS

Canada excelled at COVID-19 control early on in the pandemic, especially during the first COVID-19 shutdown. The second wave at the end of 2020 resulted in a resurgence of the outbreak, which has since been controlled. Enhanced surveillance identifies outbreaks and where there is the potential for explosive growth, which informs proactive health policy.

Sociodemographics and their impacts on risk factor awareness and beliefs about cancer and screening: results from a cross-sectional study in Newfoundland and Labrador

Background

Our objective was to examine cancer risk factor awareness and beliefs about cancer treatment, outcomes, and screening, and how these are mediated by sociodemographic variables, among Newfoundland and Labrador residents.

Methods

Participants aged 35 to 74 were recruited through Facebook advertising, and a self-administered online questionnaire was used to collect data. Descriptive statistics, Spearman rank correlations, and multivariate logistic regression analyses were performed.

Results

Of the 1048 participants who responded and met the inclusion criteria for this study, 1019 were selected for this analysis. Risk factor recognition was generally good, though several risk factors had poor awareness: being over 70 years old (53.4% respondents aware), having a low-fiber diet (65.0%), and drinking more than 1 unit of alcohol per day (62.8%). Our results showed that the participants’ awareness of risk factors was significantly associated with higher income level (r_s = 0.237, P <  0.001), higher education (r_s = 0.231, P <  0.001), living in rural regions (r_s = 0.163, P <  0.001), and having a regular healthcare provider (r_s = 0.081, P = 0.010). Logistic regression showed that among NL residents in our sample, those with higher income, post-secondary education, those in very good or excellent health, and those with a history of cancer all had higher odds of having more positive beliefs about cancer treatment and outcomes. Those with a history of cancer, and those with very good or excellent health, also had higher odds of having more positive beliefs about cancer screening. Finally, compared to Caucasian/white participants, those who were non-Caucasian/white had lower odds of having more positive beliefs about cancer screening.

Conclusion

Among adults in NL, there was poor awareness that low-fiber diets, alcohol, and age are risk factors for cancer. Lower income and education, rural residence, and not having a health care provider were associated with lower risk factor awareness. We also found a few associations between sociodemographic factors and beliefs about cancer treatment and outcomes or screening. We stress that while addressing awareness is necessary, so too is improving social circumstances of disadvantaged groups who lack the resources necessary to adopt healthy behaviours.

Rural360: incubating socially accountable research in the Canadian North

People in Northern Newfoundland and Coastal Labrador (NNCL), Canada, face major challenges obtaining accessible and contextually-relevant healthcare. Rural360 is a socially accountable research incubator that provides funding for NNCL physicians to research solutions to these issues. NNCL graduates of the adjoined 6for6 research training program for rural physicians are invited to submit the research project they have conceptualised as part of that initiative as a letter of intent, and subsequently as a research proposal, to Rural360. These submissions are reviewed by relevant subject matter experts as part of the Rural360 adjudication process. This process is iterative and strives to guide and assist participants in refining their submission. The overarching objective of Rural360 is to collaborate with rural physicians to conduct, disseminate or otherwise catalyze unsupported community-based research in NNCL. In so doing, it is highly socially accountable, empowering participants to become change-makers who investigate contextually important health issues that emerge from NNCL communities.

Evaluating the experience of rural individuals with prostate and breast cancer participating in research via telehealth

INTRODUCTION

Studies that use objective assessments often only recruit individuals in the geographic region in which the study is being conducted, because the assessments require that the researcher and participant be face to face. This limits the number and variety of individuals who can participate. Telehealth is one approach that could be used to increase sample size and representativeness. The present analysis aims to evaluate the experience of individuals diagnosed with breast or prostate cancer, who participated by telehealth in studies investigating the effects of cancer treatment on sleep and cognition. Specifically, this study aimed to highlight potential benefits of using telehealth and identify ways to improve the process for future studies and assessments.

METHODS

Telephone interviews were conducted with 20 individuals with cancer who participated via telehealth in a larger study investigating the effects of cancer treatment on sleep and cognition; 12 individuals had breast cancer and 8 individuals had prostate cancer. Participants were organized into the four regional health authorities of Newfoundland and Labrador: Eastern, Western, Central, and Grenfell-Labrador. Participants of varying ages and communities were purposively selected. Participants were interviewed about their experience participating in the study via telehealth and invited to offer suggestions for how to improve the process. Interview transcripts were coded using a thematic analysis approach. Demographic information was used to characterize the sample.

RESULTS

Including telehealth as an option in the overall study allowed for a 55% sample size increase for participants with breast cancer, and a 45% sample size increase for participants with prostate cancer. Participants reported an overall positive experience (70% reported the experience as good and/or great), with telehealth allowing for greater convenience, more personable interactions, increased access, and an otherwise unavailable opportunity to help others and themselves. Identified areas for improvement were sound quality, and better access for those who still face barriers of commuting to telehealth locations. Inter-rater reliability yielded a 92% agreement.

CONCLUSIONS

For studies and assessments requiring face-to-face contact, telehealth is clearly a feasible option for improving research representativeness and access for individuals residing in rural areas. Future research should make use of telehealth services, to give a voice to rural individuals who are too often left out.

"Everything Possible Is Being Done": Labour, Mobility, and the Organization of Health Services in Mid-20th Century Newfoundland

This article is the Presidential Address to the 2018 meeting of the Canadian Society for the History of Medicine at the University of Regina. It examines the organization of the nursing service in Newfoundland during the 1950s and 1960s, as well as the recruitment and retention of nurses in cottage hospitals and nursing stations in outport communities. A number of interconnected strategies were used by the Newfoundland government to staff the nursing service, including recruiting internationally educated nurses, adjusting expectations with respect to registration standards, and using both trained and untrained workers to support nurses' labour. Although this article is intended more as a reconnaissance suggesting the possibilities of such research, it does analyze the interconnected issues of geography, funding and pay, the nursing shortage, and the renegotiation of nursing labour that characterized this period. Furthermore, although this is a case study of Newfoundland and Labrador, it is worth considering how, or whether, the linked strategies used in the province were transferable to other communities across rural, remote, or northern Canada.

Screening of BMPR1a for pathogenic mutations in familial colorectal cancer type X families from Newfoundland

The Canadian province of Newfoundland and Labrador (NL) reports one of the highest incidence rates of familial colorectal cancer (CRC) worldwide. The NL population is an invaluable resource for studying genetic disorders because of a unique ancestry, and a willingness to participate in research studies. Familial colorectal cancer type X (FCCTX) describes a cluster of families with strong predisposition for CRC, of unknown etiology. A putative link between FCCTX and BMPR1a mutations has been identified in the Finnish population; however these findings have not been independently replicated. To investigate a potential connection between BMPR1a and FCCTX, we screened a cohort of 22 probands from unrelated NL FCCTX families using Sanger sequencing. This analysis did not independently replicate findings seen in Finland; as no candidate pathogenic BMPR1a mutations were uncovered. Our findings highlight that BMPR1a mutations are not a major contributor of FCCTX incidence in NL. Further investigation of additional FCCTX populations may assist in delineating a role for BMPR1a, if any, in FCCTX globally.

All-terrain vehicle-related injuries and deaths in Newfoundland and Labrador between 2003 and 2013: a retrospective trauma registry review

BACKGROUND

Injury and death involving all-terrain vehicles (ATV) has been reported in a number of Canadian provinces. The objective of this study is to describe the frequency, nature, severity, population affected, immediate health costs, efficacy of related legislation, and helmet use in ATV related injuries and deaths in Newfoundland and Labrador (NL).

METHODS

A retrospective review of injured or deceased ATV riders of all ages entered in the Newfoundland and Labrador Trauma Registry from 2003 to 2013 was conducted. Variables studied included demographics, injury type and severity, use of helmets, admission/discharge dates, and referring/receiving institution. Data was also obtained from the Newfoundland and Labrador Center for Health Information (NLCHI) and included all in-hospital deaths and hospitalizations due to ATVs between 1995 and 2013.

RESULTS

There were a total of 298 patients registered in the trauma registry, resulting in 2759 admission days, nine deaths, and a total estimated immediate healthcare system cost in excess of $1.6 million. More males (N=253, 84.9%) than females (N=45, 15.1%) were injured in ATV related incidents, t(20)=7.12, p<.0001. Head and thorax injuries were the most serious. 38.6% of patients were confirmed to be wearing helmets. Mean injury severity scores are as follows: head injury (M=11, SD=9.51), thorax (M=10, SD=8.3), abdominal/pelvis (M=9, SD=7.62), upper extremity (M=9, SD=8.53), other injuries (M=9, SD=10.56) lower extremity (M=8, SD=8.34), and spine (M=8, SD=6.52).

CONCLUSIONS

This study describes ATV related injuries and deaths in NL. Information from this study may guide physician practice, public education, and future legislation.

Association of type 1 diabetes and concentrations of drinking water components in Newfoundland and Labrador, Canada

OBJECTIVE

To determine the association between drinking water quality and rates of type 1 diabetes in the Newfoundland and Labrador (NL) population, which has one of the highest incidences of type 1 diabetes reported globally.

RESEARCH DESIGN AND METHODS

The study used a community-based, case-control design. We first calculated incidence rates of type 1 diabetes at the provincial, regional and community levels. The connection between incidence rates and components in public water supplies were then analyzed in three ways: to evaluate differences in water quality between communities with and without incident cases of type 1 diabetes, and to analyze the relationship between water quality and incidence rates of type 1 diabetes at both the community and regional levels.

RESULTS

The provincial incidence of type 1 diabetes was 51.7/100 000 (0-14 year age group) for the period studied. In the community-based analysis, there were significant associations found between higher concentrations of arsenic (β=0.268, P=0.013) and fluoride (β=0.202, P=0.005) in drinking water and higher incidence of type 1 diabetes. In the regional analysis, barium (β=-0.478, P=0.009) and nickel (β=-0.354, P=0.050) concentrations were negatively associated with incidence of type 1 diabetes.

CONCLUSIONS

We confirmed the high incidence of type 1 diabetes in NL. We also found that concentrations of some components in drinking water were associated with higher incidence of type 1 diabetes, but no component was found to have a significant association across the three different levels of analysis performed.

The Impact of Access Barriers on Fertility Treatment Decision Making: A Qualitative Study From the Perspectives of Patients and Service Providers

OBJECTIVE

The purpose of this study was to explore how barriers to accessing fertility services affect the treatment decisions made by fertility patients and service providers in Newfoundland and Labrador.

METHODS

Semistructured, in-depth interviews were conducted with 11 patients across Newfoundland and with eight service providers from Newfoundland and Labrador Fertility Services (located in St. John's) to gather the perspectives of both patients and providers. The interview transcripts were analyzed thematically.

RESULTS

Patients' responses to fertility service access barriers included choosing cheaper drugs, substituting intrauterine insemination (IUI) for IVF or not using IVF, delaying IVF, choosing more accessible IVF clinics, transferring multiple embryos, and stopping treatment altogether. Some patients, however, noted that the barriers would not stop them from continuing with treatment. Providers' responses to the barriers patients faced included changing drug protocols, manipulating ovulation, providing teleconsultations, and minimizing patients' clinic visits for those living some distance away from St. John's.

CONCLUSION

Both patients and providers make treatment-related decisions to maximize the likelihood of a successful pregnancy and to reduce costs, which can result in less effective care and at times increased risk to the patient. Unlike with other types of care, responses to barriers to fertility treatment largely result in changes to individual patient treatment plans rather than changing models of care. As a result, many patients must continue to seek fertility services in large urban centres and incur substantial personal costs.

Two new species and new provincial records of aleocharine rove beetles from Newfoundland and Labrador, Canada (Coleoptera, Staphylinidae, Aleocharinae)

Two new species, Atheta pseudovestita Klimaszewski & Langor, sp. n., Silusa prettyae Klimaszewski & Langor, sp. n., are described, and 16 new provincial records, including one new country record, of aleocharine beetles are presented for the province of Newfoundland and Labrador. Diagnostics, images of habitus and genital structures, distribution, bionomics information and new locality data are provided for the newly recorded species. A new checklist with 189 species of aleocharines recorded from the province is presented.
