OBJECTIVE To assess the effectiveness of the pandemic influenza A/H1N1 vaccine used in Canada during autumn 2009. DESIGN Test negative incident case-control study based on sentinel physician surveillance system. SETTING Community based clinics contributing to sentinel networks in British Columbia, Alberta, Ontario, and Quebec, Canada. PARTICIPANTS 552(More)
BACKGROUND Administrative databases provide efficient methods to estimate influenza vaccine effectiveness (IVE) against severe outcomes in the elderly but are prone to intractable bias. This study returns to one of the linked population databases by which IVE against hospitalization and death in the elderly was first assessed. We explore IVE across six more(More)
BACKGROUND In late spring 2009, concern was raised in Canada that prior vaccination with the 2008-09 trivalent inactivated influenza vaccine (TIV) was associated with increased risk of pandemic influenza A (H1N1) (pH1N1) illness. Several epidemiologic investigations were conducted through the summer to assess this putative association. METHODS AND(More)
BACKGROUND The feasibility and acceptability of Internet-based sexually transmitted infection (STI) testing have been demonstrated; however, few programs have included testing for human immunodeficiency virus (HIV). In British Columbia, Canada, a new initiative will offer online access to chlamydia, gonorrhea, syphilis, and HIV testing, integrated with(More)
Suicide is the second leading cause of death in youth globally; however, there is uncertainty about how best to intervene. Suicide rates are typically higher in males than females, while the converse is true for suicide attempts. We review this "gender paradox" in youth, and in particular, the age-dependency of these sex/gender differences and the(More)
OBJECTIVE To characterize the first-wave epidemiologic features of influenza-like illness (ILI) associated with the novel pandemic A/H1N1 [A(H1N1)pdm09] virus. METHODS We used generalized linear mixed models (GLMM) to assess risk factors and non-parametric and/or parametric distributions to estimate attack rates, secondary attack rates (SAR), duration of(More)
AIM The burden of disease in children attributable to influenza viruses is difficult to quantify given the similarity of symptoms caused by infection due to influenza and other viruses. This uncertainty impacts clinical decision-making and estimates of burden. We aimed to systematically review the literature to determine the proportion of healthy children(More)
BACKGROUND Testing for sexually transmitted and blood-borne infections (STBBI) is an effective public health strategy that can promote personal control of one's health and prevent the spread of these infections. Multiple barriers deter access to testing including fear of stigmatization, inaccurate health care provider perceptions of risk, and reduced(More)
BACKGROUND While several studies have demonstrated that gay and bisexual men are at increased risk of suicide less attention has been given to the processes that generate the inherent inequity with the mainstream population. This study tested whether syndemic theory can explain the excess suicide burden in a sample of Canadian gay and bisexual men. Syndemic(More)
