BACKGROUND: Many concussion symptoms, such as headaches, vision problems, or difficulty remembering or concentrating may deleteriously affect school functioning. Our objective was to determine if academic performance was lower in the academic calendar year that students sustain a concussion compared to the previous year when they did not sustain a concussion. METHODS: Using Manitoba Health and Manitoba Education data, we conducted a population-based, controlled before-after study from 2005-2006 to 2010-2011 academic years...

This study assessed links between racism and oral health outcomes among pregnant Canadian Aboriginal women. Baseline data were analyzed for 541 First Nations (94.6%) and Métis (5.4%) women in an early childhood caries preventive trial conducted in urban and on-reserve communities in Ontario and Manitoba. One-third of participants experienced racism in the past year determined by the Measure of Indigenous Racism Experience. In logistic regressions, outcomes significantly associated with incidents of racism included: wearing dentures, off-reserve dental care, asked to pay for dental services, perceived need for preventive care, flossing more than once daily, having fewer than 21 natural teeth, fear of going to dentist, never received orthodontic treatment and perceived impact of oral conditions on quality of life...

BACKGROUND: Policy dialogues are critical for developing responsive, effective, sustainable, evidence-informed policy. Our multidisciplinary team, including researchers, physicians and senior decision-makers, comprehensively evaluated The Winnipeg Central Intake Service, a single-entry model in Winnipeg, Manitoba, to improve patient access to hip/knee replacement surgery. We used the evaluation findings to develop five evidence-informed policy directions to help improve access to scheduled clinical services across Manitoba...

Poor eating habits among children are associated with negative health outcomes. The objective of this study was to use pulse/soy consumption as an indicator to evaluate the eating profile of young Manitobans. Data from the Canadian Community Health Survey Cycle 2.2 were used for analysis and restricted to Manitoba residents aged 2 to 18 years (n = 1840). Consumers were identified as individuals who reported eating at least 1 pulse/soy product during their recall. On any given day, 8.2% of Manitobans reported consumption of pulses/soy...

OBJECTIVE: To examine associations between breastfeeding initiation and subsequent diabetes among First Nations (indigenous people in Canada who are not Métis or Inuit) and non-First Nations mothers and their offspring with and without gestational diabetes mellitus (GDM). METHODS: This retrospective database study included 334,553 deliveries (1987-2011) in Manitoba with up to 24 years of follow-up for diabetes using population-based databases. Information of breastfeeding initiation before hospital discharge was obtained from hospital abstracts recorded by nurses in postpartum wards...

BACKGROUND & AIMS: We aimed to assess levels of education attained, employment, and marital status of adults diagnosed with inflammatory bowel diseases (IBD) during childhood or adolescence, compared with healthy individuals in Canada. METHODS: We performed a cross-sectional study of adults diagnosed with IBD in childhood or adolescence, at Children's Hospital in Winnipeg, Manitoba from January 1978 through December 2007. Participants (n=112) answered a semi-structured questionnaire on educational achievements, employment, and marital status...

BACKGROUND: Scientists have called for strategies to identify ED patients with unmet needs. We identify the unique profile of ED patients who arrive by ambulance and subsequently leave without consulting a provider (ie, a paradoxical visit, PV). METHODS: Using a retrospective cohort design, administrative data from Winnipeg, Manitoba were interrogated to identify all ED patients 17+ years old as having zero, single or multiple PVs in 2012/2013. Analyses compare the sociodemographic, physical (eg, arthritis), mental (eg, substance abuse) and concurrent healthcare use profile of non-PV, single and multiple PV patients...

BACKGROUND: Patients with Parkinson's disease (PD) and/or Parkinsonism are affected by a complex burden of comorbidity. Many ultimately require institutional care, where they may be subject to the application of physical restraints or the prescription of antipsychotic medications, making them more vulnerable to adverse outcomes. OBJECTIVES: The objectives of this paper are to: 1) describe the clinical complexity of older institutionalized persons with PD; and 2) examine patterns and predictors of restraint use and prescription of antipsychotics in this population...

BACKGROUND: The heterogeneity of medical complications that lead to amputation has resulted in a diverse patient population with differing rehabilitation needs; however, the rehabilitation trends for patients with lower extremity amputations across Canada have not been studied previously. OBJECTIVE: To describe trends in rehabilitation after lower extremity amputations and the factors affecting rehabilitation length of stay in Canada. DESIGN: Retrospective cohort analysis...

OBJECTIVES: Comorbid depression and anxiety are common in inflammatory bowel disease (IBD), but few population-based estimates of the burden of depression and anxiety exist. Methods to support population-based studies are needed. We aimed to test the performance of administrative case definitions for depression and anxiety in IBD and to understand what the prevalence estimated using such definitions reflects. METHODS: We linked administrative (health claims) data from the province of Manitoba, Canada with clinical data for 266 persons in the Manitoba IBD Cohort Study...

INTRODUCTION: Fetal alcohol spectrum disorder (FASD) is a significant public health concern. To prevent FASD, factors that place women at risk for giving birth to children with FASD must be investigated; however, there are little data in this area. This paper describes the development of the Manitoba mothers and FASD study, a retrospective cohort of mothers whose children were diagnosed with FASD, generated to investigate: (1) risk factors associated with giving birth to children with FASD; (2) maternal physical and health outcomes, as well as the usage of health and social services...

Ammonia being a nutrient facilitates the growth of algae in wastewater and causes eutrofication. Nitrate poses health risk if it is supplied in drinking water. Hence, nitrogen removal from wastewater is required. Lagoon wastewater treatment systems have become common in Canada these days. The study was conducted to understand the nitrogen removal mechanisms from the existing wastewater treatment lagoon system in the town of Lorette, Manitoba. The lagoon system consists of two primary aerated cells and two secondary unaerated cells...

Polar bears (Ursus maritimus) have adapted to an annual cyclic regime of feeding and fasting, which is extreme in seasonal sea ice regions of the Arctic. As a consequence of climate change, sea ice breakup has become earlier and the duration of the open-water period through which polar bears must rely on fat reserves has increased. To date, there is limited empirical data with which to evaluate the potential energetic capacity of polar bears to withstand longer fasts. We measured the incoming and outgoing mass of inactive polar bears (n = 142) that were temporarily detained by Manitoba Conservation and Water Stewardship during the open-water period near the town of Churchill, Manitoba, Canada, in 2009-2014...

Soon after the emergence of 2009 pandemic H1N1, the first outbreaks in breeder turkey operations were reported that implicated human-to-turkey transmission. In the spring of 2016, the reoccurrence of 2009 pandemic H1N1 lineage viruses infecting breeder turkey flocks in Ontario and Manitoba, Canada, also implicated human-to-turkey transmission. In addition to raising concerns over biosecurity and vaccine failures, these cases once again raise the issue of whether turkeys have the potential to act as a bridge species to generate novel influenza A virus reassortants with public health implications...
