An assessment of antimicrobial resistant disease threats in Canada.

Background: Antimicrobial resistance (AMR) of infectious agents is a growing concern for public health organizations. Given the complexity of this issue and how widespread the problem has become, resources are often insufficient to address all concerns, thus prioritization of AMR pathogens is essential for the optimal allocation of risk management attention. Since the epidemiology of AMR pathogens differs between countries, country-specific assessments are important for the determination of national priorities.

Estimating sensitivity of laboratory testing for influenza in Canada through modelling.

Background: The weekly proportion of laboratory tests that are positive for influenza is used in public health surveillance systems to identify periods of influenza activity. We aimed to estimate the sensitivity of influenza testing in Canada based on results of a national respiratory virus surveillance system.

Methods And Findings: The weekly number of influenza-negative tests from 1999 to 2006 was modelled as a function of laboratory-confirmed positive tests for influenza, respiratory syncytial virus (RSV), adenovirus and parainfluenza viruses, seasonality, and trend using Poisson regression.

Health outcomes of low-dose ionizing radiation exposure among medical workers: a cohort study of the Canadian national dose registry of radiation workers.

Background: Medical workers can be exposed to low-dose ionizing radiation from various sources. The potential cancer risks associated with ionizing radiation exposure have been derived from cohort studies of Japanese atomic bomb survivors who had experienced acute, high-level exposure. Since such extrapolations are subject to uncertainty, direct information is needed on the risk associated with chronic low-dose occupational exposure to ionizing radiation.

Developing integrative primary healthcare delivery: adding a chiropractor to the team.

Background: The use of complementary and alternative medicine has been increasing in Canada despite the lack of coverage under the universal public health insurance system. Physicians and other healthcare practitioners are now being placed in multidisciplinary teams, yet little research on integration exists.

Objective: We sought to investigate the effect of integrating chiropractic on the attitudes of providers on two healthcare teams.

Chiropractic care of musculoskeletal disorders in a unique population within Canadian community health centers.

Objective: This study was part of a larger demonstration project integrating chiropractic care into publicly funded Canadian community health centers. This pre/post study investigated the effectiveness of chiropractic care in reducing pain and disability as well as improving general health status in a unique population of urban, low-income, and multiethnic patients with musculoskeletal (MSK) complaints.

Methods: All patients who presented to one of two community health center-based chiropractic clinics with MSK complaints between August 2004 and December 2005 were recruited to participate in this study.

Epidemiology of testicular cancer: an overview.

Testicular cancer is a rare disease, accounting for 1.1% of all malignant neoplasms in Canadian males. Despite the low overall incidence of testicular cancer, it is the most common malignancy among young men.

Decreases in occupational exposure to ionizing radiation among Canadian dental workers.

Objective: To describe doses of ionizing radiation and their possible associations with mortality rates and cancer incidence among Canadian dental workers.

Methods: The National Dose Registry (NDR) of Canada was used to assess occupational dose of ionizing radiation received by dental workers. The NDR cohort includes 42,175 people classified as dental workers.

Dietary risk factors for testicular carcinoma.

Although testicular cancer is a relatively rare lesion, accounting for only 1.1% of all malignant neoplasms in males in Canada, it is the most common cancer among Canadian men 20-45 years of age. Knowledge of the causes of testicular cancer risk in general, and more specifically, its association with diet, remain limited.

Gradients in risk for youth injury associated with multiple-risk behaviours: a study of 11,329 Canadian adolescents.

This study used the Canadian version of the World Health Organization-Health Behaviour in School-Aged Children (WHO-HBSC) Survey to examine the role of multiple risk behaviours and other social factors in the etiology of medically attended youth injury. 11,329 Canadians aged 11-15 years completed the 1997-1998 WHO-HBSC, of which 4152 (36.7%) reported at least one medically attended injury.
