BACKGROUND: Mothers have increased mental illness such as anxiety and depression after the death of a child. We examine the duration of this worsening of mental health. METHODS: The mental health of all mothers who experience the death of an infant (< 1 years old) in Manitoba, Canada between April 1, 1999 and March 31, 2011 (n = 534) is examined in the 4 years leading up to, and the 4 years following, the death of their child. Mental health-related outcomes of these mothers are compared with a matched (3:1) cohort of mothers who did not experience the death of a child (n = 1,602)...

"It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity." The opening line of Dickens's A Tale of Two Cities could easily be the dramatic opening line of a summary of the establishment of a satellite medical school campus in Manitoba. Reflection on my last four years as associate dean reveals that most of the descriptors in that famous sentence at one time or another were apropos. This brief essay will relate the experiences of the last four years and some of the lessons learned along the way...

INTRODUCTION: High rates of mental health problems, such as suicidal behaviours, among First Nations youth in Canada are a major public health concern. The Good Behavior Game (GBG) is a school-based intervention that provides a nurturing environment for children and has been shown to promote positive outcomes. PAX Good Behavior Game (PAX GBG) is an adaptation and enhancement of the GBG. While PAX GBG has been implemented in Indigenous communities, little research exists examining the cultural and contextual appropriateness and effectiveness of the intervention in First Nations communities...

BACKGROUND: Aboriginal peoples in Canada are comprised of First Nations, Métis, and Inuit. Health care services for First Nations who live on rural and remote reserves are mostly provided by the Government of Canada through the federal department, Health Canada. One Health Canada policy, the evacuation policy, requires all First Nations women living on rural and remote reserves to leave their communities between 36 and 38 weeks gestational age and travel to urban centres to await labour and birth...

This paper documents the association between water and sanitation infrastructure and health indicators in Canada for First Nations, Métis and Inuit individuals living on and off-reserve in Canada. We use two data sources: the Aboriginal Peoples Survey and a survey conducted in a First Nations community in northern Manitoba-St. Theresa Point First Nation. We find statistically significant relationships between water infrastructure and health status in both sources of data. In particular, among individuals living off-reserve, contaminated water is associated with a 5-7% lower likelihood of reporting good self-rated health and a 4% higher probability of reporting a health condition or stomach problem...

Two internationally recognised and standardised genotyping methods, mycobacterial interspersed repetitive unit and variable number tandem repeat analysis (MIRU-VNTR) and spoligotyping, were applied to characterise genetic variations among 137 Mycobacterium bovis isolates recovered from Canadian domestic and wild animals during 1985-2015. Spoligotyping generated seven types that were discriminated further into12 MIRU-VNTR types. The discriminatory power indexes were estimated as 0.71 and 0.77 for spoligotyping and MIRU-VNTR typing approaches, respectively...

Among 62,275 women and 6455 men, FRAX stratified risk for incident major osteoporotic fracture (MOF) and incident hip fracture (HF) without sex interaction. Performance was good in those with osteoporosis regardless of how this was defined. INTRODUCTION: Some studies have reported that FRAX performance differs according to sex and/or osteoporosis definitions. We evaluated whether the performance of FRAX to predict incident MOF and HF in women and men was affected by the presence or absence of osteoporosis defined by World Health Organization (WHO) or National Osteoporosis Foundation (NOF) criteria...

Background: Acute kidney injury (AKI) following cardiac surgery leads to increased morbidity and mortality. Characterization and validation of early biomarkers of AKI may ultimately facilitate early therapeutic intervention. We have previously identified that elevated urinary hepcidin-25 is inversely and independently associated with the development of AKI in adult cardiac surgery patients. Hepcidin-25 is an antimicrobial peptide that sequesters iron intracellularly, and its elevation following human ischemia reperfusion injury may represent a renoprotective response to minimize renal injury...

Lumbar spine trabecular bone score (TBS) can be used to modify the output from the fracture risk assessment tool, FRAX, to enhance fracture prediction. An alternative approach for using TBS in clinical practice, based upon an adjustment to the bone mineral density (BMD) T-score, may be helpful in regions where intervention guidelines and/or reimbursement are primarily based on BMD T-score. INTRODUCTION: The aim of this study is to develop an approach for using TBS in clinical practice based upon a "risk-equivalent" adjustment to the BMD T-score...

Unmanned aircraft systems (UAS) are relatively new technologies gaining popularity among wildlife biologists. As with any new tool in wildlife science, operating protocols must be developed through rigorous protocol testing. Few studies have been conducted that quantify the impacts UAS may have on unhabituated individuals in the wild using standard aerial survey protocols. We evaluated impacts of unmanned surveys by measuring UAS-induced behavioral responses during the nesting phase of lesser snow geese (Anser caerulescens caerulescens) in Wapusk National Park, Manitoba, Canada...

This study explored the possible factors associated with psychological distress in adults with inflammatory bowel disease (IBD) and also engagement in mental health services (MHS) in those reporting distress in a large Australian cohort. Participants with IBD completed an online survey assessing perceived IBD activity (Manitoba Index; MI), mental health status (K10), demographic details, and engagement with MHS for IBD-associated issues. Of 336 participants, 76.5% perceived themselves as having active disease over the past 6 months, and on K10 scores, 51...

The recent introduction of Zika virus (ZIKV) into the Americas and the occurrence of birth defects associated with infection during pregnancy have created a concern about the spread of this virus into more northern countries in the Americas. Therefore, we examined several species of mosquitoes found in southern Manitoba, Canada, for their susceptibility to infection and their ability to transmit ZIKV. Aedes cinereus, Ae. euedes, Ae. fitchii, Ae. sticticus, Ae. vexans, Coquillettidia perturbans, Culex restuans, and Cx...

OBJECTIVE: Recently, there has been great interest in the use, abuse and over-prescribing of opioid analgesics for children. However, there is a paucity of evidence on patterns of prescribing of both narcotic and non-narcotic analgesics for children by dentists. METHODS: We used a population-wide prescription drug database (PharmaNet) in British Columbia, Canada, to examine prescribing and dispensing of analgesics surrounding dental procedures. We examined all drugs prescribed for children by dentists between 1997 and 2013, as we had access to data on drug doses and days of medication supply...

OBJECTIVE: Improvements in clinical risk prediction models for osteoporosis-related fracture can be evaluated using area under the receiver operating characteristic (AUROC) curve and calibration, as well as reclassification statistics such as the net reclassification improvement (NRI) and integrated discrimination improvement (IDI) statistics. Our objective was to compare the performance of these measures for assessing improvements to an existing fracture risk prediction model. We simulated the effect of a new, randomly-generated risk factor on prediction of major osteoporotic fracture (MOF) for the internationally-validated FRAX® model in a cohort from the Manitoba Bone Mineral Density (BMD) Registry...

Kernel morphology characteristics of wheat are complex and quantitatively inherited. A doubled haploid (DH) population of the cross RL4452/'AC Domain' was used to study the genetic basis of seed shape. Quantitative trait loci (QTL) analyses were conducted on a total of 18 traits: 14 grain shape traits, flour yield (Fyd), and three agronomic traits (Plant height [Plht], 1000 Grain weight [Gwt], Test weight [Twt]), using data from trial locations at Glenlea, Brandon, and Morden in Manitoba, Canada, between 1999 and 2004...

OBJECTIVES: Fatal accidents often lead to policy changes. However, the existing decision-making environment is critical to policy responses. This study compares the policy responses to similar events in Manitoba and Saskatchewan. The key question explores the extent to which the policy decisions in each province differ despite the similarity of the events. METHODS: Key documents were examined. Provincial court rulings, workplace health & safety incident investigation reports, court transcripts and police reports were used to compare resulting policy changes as well as the socio-political and economic decision-making context...

OBJECTIVES: Although individuals living in areas with lower household income have been shown to have higher rates of mortality from colorectal cancer (CRC), findings on the effect of income on CRC incidence in countries with universal health care have been inconsistent. There are limited data from Canada. We investigated the geographic variation and factors associated with CRC incidence in Manitoba, a central Canadian province. METHODS: The Manitoba Cancer Registry and Manitoba Health population registry were used to determine age-sex-standardized CRC incidence rates between 1985 and 2012, which were geocoded to 498 small geographic areas (SGAs)...

Lung cancer (LC) is the leading cause of death of cancer in Canada in both men and women, and indoor radon is the second leading cause of LC after tobacco smoking. The Population Attributable Risk (PAR) is used to assess radon exposure risk. In this work we estimate the burden of LC in some Canadian provinces. We use the PAR to identify the radon levels responsible for most LC cases. Finally, we use the PAR function of the two variables, radon action and target levels, to search for a possible optimal mitigation program...
