Natural mortality of Atlantic sturgeon (Acipenser oxyrinchus) has been determined to be low (M = 0.07). Reported herein is the mortality by beach stranding of 11 Atlantic sturgeon in Scot's Bay, part of the inner Bay of Fundy in Nova Scotia, Canada on 22 June 2014. Genetic analyses, histological analysis and age determination were performed to determine origin, maturity stage and age of the stranded Atlantic sturgeon. Microsatellite and mitochondrial DNA analyses indicated that four of the Atlantic sturgeon (2 males and 2 females) were from the Saint John River, NB population, which was designated as threatened by the Committee on the Status of Endangered Wildlife in Canada...

Chronic obstructive pulmonary disease (COPD) is a leading cause of death, morbidity, and health-care spending. The Halifax, Nova Scotia-based INSPIRED COPD Outreach Program™ has proved highly beneficial for patients and the health-care system. With direct investment of <$1-million CAD, a pan-Canadian quality improvement collaborative (QIC) supported the spread of INSPIRED to 19 teams in the 10 Canadian provinces contingent upon participation in evaluation. The collaborative evaluation followed a mixed-methods summative approach relying on collated quantitative data, team documents, and surveys sent to core members of the 19 teams...

A neotype of Amphitrite Müller (1771) is established and re-described, using material collected in 2001 from near the type locality on the southwest coast of Iceland. We examined material from Iceland, Nova Scotia and Newfoundland, identified as Pseudopotamilla reniformis, showing scissiparity and commonly found in aggregations within kelp holdfasts or amongst encrusting fauna. By contrast, scissiparity has not been seen in a population recorded as P. reniformis from Wales (broadcast spawning is presumed, Chughtai & Knight-Jones 1988), which bores into limestone and that the present analysis shows to belong to a different species from P...

Recruitment is a key demographic process for population persistence. This paper focuses on barnacle (Semibalanus balanoides) recruitment. In rocky intertidal habitats from the Gulf of St. Lawrence coast of Nova Scotia (Canada), ice scour is common during the winter. At the onset of intertidal barnacle recruitment in early May (after sea ice has fully melted), mostly only adult barnacles and bare substrate are visible at high elevations in wave-exposed habitats. We conducted a multiannual study to investigate if small-scale barnacle recruitment could be predicted from the density of pre-existing adult barnacles...

INTRODUCTION: Oncologists have traditionally been responsible for providing routine follow-up care for cancer survivors; in recent years, however, primary care providers (pcps) are taking a greater role in care during the follow-up period. In the present study, we used a longitudinal multi-province retrospective cohort study to examine how primary care and specialist care intersect in the delivery of breast cancer follow-up care. METHODS: Various databases (registry, clinical, and administrative) were linked in each of four provinces: British Columbia, Manitoba, Ontario, and Nova Scotia...

Background.: Family physicians (FPs) are expected to take on new patients fairly and equitably and to not discriminate based on medical or social history. 'Meet and greet' appointments are initial meetings between physicians and prospective patients to establish fit between patient needs and provider scope of practice. The public often views these appointments as discriminatory; however, there is no empirical evidence regarding their prevalence or outcomes. Objectives...

The Purple Sandpiper (Calidris maritima) is a medium-sized shorebird that breeds in the Arctic and winters along northern Atlantic coastlines. Migration routes and affiliations between breeding grounds and wintering grounds are incompletely understood. Some populations appear to be declining, and future management policies for this species will benefit from understanding their migration patterns. This study used two mitochondrial DNA markers and 10 microsatellite loci to analyze current population structure and historical demographic trends...

Several evidence-informed treatment guidelines recommend against the use of typical antipsychotics in patients with Parkinson's disease; of the atypical antipsychotics, clozapine and quetiapine are preferred. The purpose of this study is to determine the frequency with which potentially inappropriate antipsychotics are dispensed to older adults in Nova Scotia who are on levodopa-containing medications. In this cohort, 59.9% were dispensed a preferred atypical antipsychotic and 12.6% a potentially harmful typical antipsychotic...

Ten polyketide specialized metabolites, epoxynemanione A, nemanifuranones A-F, and nemanilactones A-C, were isolated from the culture filtrate of Nemania serpens (Pers.) Grey (1821), an endophytic fungus from a Riesling grapevine (Vitis vinifera) found in Canada's Niagara region. Additionally, four known metabolites 2-(hydroxymethyl)-3-methoxy-benzoic acid, phyllostine, 5-methylmellein and a nordammarane triterpenoid were isolated. A related known metabolite 2,3-dihydro-2-hydroxy-2,4-dimethyl-5-trans-propenylfuran-3-one has also been included for structural and biological comparison to the nemanifuranones...

BACKGROUND: Degenerative processes in neurodegenerative diseases can start years before clinical manifestation. We aimed to establish whether a multiple sclerosis prodromal period exists by examining patterns of health-care use before a first demyelinating event. METHODS: In this matched cohort study, we used data from linked health administrative and clinical databases from four Canadian provinces (British Columbia, Saskatchewan, Manitoba, and Nova Scotia) to compare hospital, physician, and prescription use data from people with multiple sclerosis and matched general population controls in the 5 years before the first demyelinating disease claim (health administrative index date) or clinically reported symptom onset (clinical index date)...

Genomic studies of invasive species can reveal both invasive pathways and functional differences underpinning patterns of colonization success. The European green crab (Carcinus maenas) was initially introduced to eastern North America nearly 200 years ago where it expanded northwards to eastern Nova Scotia. A subsequent invasion to Nova Scotia from a northern European source allowed further range expansion, providing a unique opportunity to study the invasion genomics of a species with multiple invasions...

Invasive species have been associated with significant negative impacts in their introduced range often outcompeting native species, yet the long-term evolutionary dynamics of biological invasions are not well understood. Hybridization, either among waves of invasion or between native and introduced populations, could alter the ecological and evolutionary impacts of invasions yet has rarely been studied in marine invasive species. The European green crab (Carcinus maenas) invaded eastern North America twice from northern and southern locations in its native range...
