Situated at the furthest northeastern edge of Canada, the island of Newfoundland (approximately 110,000 km(2)) and Labrador (approximately 295,000 km(2)) today constitute a province characterized by abundant natural resources but low population density. Both landmasses were covered by the Laurentide ice sheet during the Last Glacial Maximum (18,000 years before present [YBP]); after the glacier retreated, ice patches remained on the island until ca. 9,000 calibrated (cal) YBP [1]. Nevertheless, indigenous peoples, whose ancestors had trekked some 5,000 km from the west coast, arrived approximately 10,000 cal YBP in Labrador and ca...

Most anthropogenic marine debris shoreline studies are conducted on sandy shores, rather than rocky coastlines. We amended a standardized protocol for monitoring marine debris on a high-loading beach composed of small rocks and cobbles in Newfoundland, Canada. Our protocol had two parts: we conducted stratified sampling to a depth of ~20cm below the surface of the rocks (standing survey), and surveyed accumulation of items on the surface of rocks every other day (loading survey). We found the vast majority of smaller items were below the surface...

BACKGROUND: Physician turnover, involving physicians' leaving clinical practice in a specific area, may disrupt continuity of care, leading to poorer health outcomes and greater use of health care services. The purpose of this study was to investigate the relation between family physician retention and avoidable hospital admission for ambulatory-care-sensitive conditions. METHODS: We conducted a population-based cross-sectional study using provincial health administrative data for residents of Newfoundland and Labrador who held a provincial health card between 2001 and 2009...

Canine parvovirus-2 (CPV-2) and feline panleukopenia virus (FPV) (species Carnivore protoparvovirus 1, family Parvoviridae) cause a severe gastrointestinal disease associated with immune depression in a broad range of terrestrial carnivores. We report here the first molecular epidemiological investigation of protoparvoviruses on the Island of Newfoundland, Canada. In particular, we investigated red foxes (Vulpes vulpes deletrix) and lynx (Lynx canadensis subsolanus), two autochthonous species, and coyotes (Canis latrans), which immigrated onto the island during the 1980s...

SETTING: The majority of Canadians' food acquisition occurs in retail stores. Retail science has become increasingly sophisticated in demonstrating how consumer environments influence population-level diet quality and health status. The retail food environment literature is new but growing rapidly in Canada, and there is a relative paucity of evidence from intervention research implemented in Canada. INTERVENTION: The healthy corner store model is a comprehensive complex population health intervention in small retail stores, intended to transform an existing business model to a health-promoting one through intersectoral collaboration...

OBJECTIVE: Chronic inflammation is implicated in causing cancer. Diet plays an important role in regulating chronic inflammation by altering circulating levels of inflammatory biomarkers. Effect of single food or nutrient on cancer often is inconclusive; perhaps due to dietary interactions and multicolinearity. The aim of this study was to determine prediagnostic inflammatory potential of overall diet in relation to risk for colorectal cancer (CRC). METHODS: In all, 547 patients with CRC from Newfoundland Familial Colorectal Cancer Registry and 685 controls from the general population were identified...

Studying public perception on drinking water quality is crucial for managing of water resources, generation of water quality standards, and surveillance of the drinking-water quality. However, in policy discourse, the reliability of public perception concerning drinking water quality and associated health risks is questionable. Does the public perception of water quality equate with the actual water quality? We investigated public perceptions of water quality and the perceived health risks and associated with the actual quality of public water supplies in the same communities...

We report an α(0)-thalassemia (α(0)-thal) trait in Newfoundlanders caused by a novel 90.7 kb deletion. The deletion, designated the Newfoundland deletion (- -(NFLD)), removes both the HBA2 and HBA1 genes, while leaving the HBZ gene intact. The 5' deletion endpoint is within the HBAP1 pseudogene, approximately 3.7 kb upstream of the HBA2 gene. The 3' deletion endpoint is approximately 82.5 kb downstream of the HBA1 gene, within the second intervening sequence (IVS-II) of the FAM234A gene. This is the second α(0)-thal deletion reported in Newfoundland families of northern European descent...

Ty Bereskie, Husnain Haider, Manuel J Rodriguez, Rehan Sadiq
Traditional approaches for benchmarking drinking water systems are binary, based solely on the compliance and/or non-compliance of one or more water quality performance indicators against defined regulatory guidelines/standards. The consequence of water quality failure is dependent on location within a water supply system as well as time of the year (i.e., season) with varying levels of water consumption. Conventional approaches used for water quality comparison purposes fail to incorporate spatiotemporal variability and degrees of compliance and/or non-compliance...

The de novo assembly of the red fox (Vulpes vulpes) genome has facilitated the development of genomic tools for the species. Efforts to identify the population history of red foxes in North America have previously been limited by a lack of information about the red fox Y-chromosome sequence. However, a megabase of red fox Y-chromosome sequence was recently identified over 2 scaffolds in the reference genome. Here, these scaffolds were scanned for repeated motifs, revealing 194 likely microsatellites. Twenty-three of these loci were selected for primer development and, after testing, produced a panel of 11 novel markers that were analyzed alongside 2 markers previously developed for the red fox from dog Y-chromosome sequence...

In this article, we explore the subjective well-being of empty nesters who lived in rural eastern China ( N = 967). The Memorial University of Newfoundland Scale of Happiness is used to measure subjective well-being. The results indicate that Memorial University of Newfoundland Scale of Happiness is appropriate for empty nesters in rural China due to its reliability and validity. Generally, male empty nesters report greater subjective well-being scores than females. Negative factors include low levels of education, being a widow or widower, or being unmarried...

The first report of members of the spirochete genus Borrelia in the seabird tick, Ixodes uriae, and seabird colonies occurred during the early 1990s. Since then, Borrelia spp. have been detected in these ticks and seabird colonies around the world. To-date, the primary species detected has been B. garinii, with rare occurrences of B. burgdorferi sensu stricto and B. lusitaniae. During our research on Borrelia and I. uriae in seabird colonies of Newfoundland and Labrador, Canada, we have identified B. bavariensis in I...

The infectious salmon anaemia virus (ISAV) is an important viral disease of farmed Atlantic salmon that has caused considerable financial losses for salmon farmers around the world, including Atlantic Canada. It is listed as a notifiable disease by the World Organization for Animal Health, and to this day, culling of infected cages or farms remains the current practice in many countries to mitigate the spread of the virus. In Atlantic Canada, ISAV was first detected in 1996 and continues to be detected. While some outbreaks seemed to have arisen from isolated infections of unknown source, others were local clusters resulting from horizontal spread of infection...

BACKGROUND: Increased serum levels of vitamin D and calcium have been associated with lower risks of colorectal cancer (CRC) incidence and mortality. These inverse associations may be mediated by the vitamin D receptor (VDR) and the calcium-sensing receptor (CASR). We investigated genetic variants in VDR and CASR for their relevance to CRC prognosis. METHODS: A population-based cohort of 531 CRC patients diagnosed from 1999 to 2003 in Newfoundland and Labrador, Canada, was followed for mortality and cancer recurrence until April 2010...

This paper investigates patterning of /l/ in Newfoundland English. Using acoustic and ultrasound methods, the reported displacement of the traditional Irish pattern of word-final light /l/ is assessed. Acoustic results show darker /l/'s in word-final position in both phrases and compounds. Although the standard allophonic pattern is widespread in Newfoundland English, dialectal variation arising from early settlement patterns continues to influence speech patterns with less distinction between initial and final /l/ in Irish-settled areas...

Invertebrates from various marine habitats form nutritional symbioses with chemosynthetic bacteria. In chemosynthetic symbioses, both the mode of symbiont transmission and the site of bacterial housing can affect the composition of the symbiont population. Vertically transmitted symbionts, as well as those hosted intracellularly, are more likely to form clonal populations within their host. Conversely, symbiont populations that are environmentally acquired and extracellular may be more likely to be heterogeneous/mixed within host individuals, as observed in some mytilid bivalves...

BACKGROUND: The discovery of a new Macrococcus canis species isolated from skin and infection sites of dogs led us to question if Macrococcus spp. are common in dogs and are resistant to antibiotics. HYPOTHESIS/OBJECTIVES: To evaluate the occurrence of Macrococcus spp. in dogs, determine antibiotic resistance profiles and genetic relationships. ANIMALS: One hundred and sixty two dogs (mainly West Highland white terriers and Newfoundland dogs) were screened for the presence of Macrococcus, including six dogs with Macrococcus infections...
