Introduction: This study examines patterns of change in different smoker subgroups' responses to new pictorial health warning labels (HWLs) over the initial, two year post-implementation period in Canada, where HWLs include package inserts with cessation messages, and Australia, where "plain" packaging (i.e., prohibition of brand imagery) was also implemented. Methods: Data were collected from online consumer panels in Canada (nsmokers=3,153; nobservations=5,826) and Australia (nsmokers=2,699; nobservations=5,818) from September 2012 to September 2014, with approximately 1,000 adult smokers surveyed in each country every four months, using replenishment to maintain sample size...

BACKGROUND: The risk of hepatitis C virus (HCV) reinfection due to continued injecting risk behaviours might remain a barrier to HCV treatment among people who inject drugs. We aimed to evaluate changes in risk behaviours during and following HCV treatment among people with ongoing injecting drug use or receiving opioid substitution treatment (OST). METHODS: ACTIVATE was an international multicentre clinical trial conducted between 2012 and 2014. Participants with HCV genotypes 2/3 infection were treated with peg-interferon/ribavirin for 12 or 24 weeks and completed a self-administered behavioural questionnaire at each study visit...

The aims of this study were to establish and validate various predictive equations of half-marathon performance. Seventy-eight half-marathon male runners participated in two different phases. Phase 1 (n = 48) was used to establish the equations for estimating half-marathon performance, and Phase 2 (n = 30) to validate these equations. Apart from half-marathon performance, training-related and anthropometric variables were recorded, and an incremental test on a treadmill was performed, in which physiological (VO2max, speed at the anaerobic threshold, peak speed) and biomechanical variables (contact and flight times, step length and step rate) were registered...

The bacterium Burkholderia pseudomallei causes melioidosis, which is mainly associated with tropical areas. We analyzed single-nucleotide polymorphisms (SNPs) among genome sequences from isolates of B. pseudomallei that originated in the Western Hemisphere by comparing them with genome sequences of isolates that originated in the Eastern Hemisphere. Analysis indicated that isolates from the Western Hemisphere form a distinct clade, which supports the hypothesis that these isolates were derived from a constricted seeding event from Africa...

INTRODUCTION: Neurocardiac injury, a type of myocardial dysfunction associated with neurological insult to the brain, occurs in 31-48% of aneurysmal subarachnoid hemorrhage (aSAH) patients. Cardiac troponin I (cTnI) is commonly used to diagnose neurocardiac injury. Brain natriuretic peptide (BNP), another cardiac marker, is more often used to evaluate degree of heart failure. The purpose of this study was to examine the relationships between BNP and (a) neurocardiac injury severity according to cTnI, (b) noninvasive continuous cardiac output (NCCO), and (c) outcomes in aSAH patients...

Tooth develops through reciprocal interactions between oral epithelium and oral mesenchyme. To regenerate tooth, both components are necessary to mimic epithelial-mesenchymal interactions. In adult teeth, Hertwig's epithelial root sheath/Epithelial rests of Malassez (HERS/ERM) cells are unique epithelial cells which are derived from oral epithelium. In this study, we investigated whether HERS/ERM cells could have ameloblast-like characteristics via interaction with stem cells from human exfoliated deciduous teeth (SHEDs) as an oral mesenchymal component...

BACKGROUND: The aim was to estimate an exchange rate between EQ-5D-3L and the Adult Social Care Outcome Tool (ASCOT) using preference-based mapping via common time trade-off (TTO) valuations. EQ-5D and ASCOT are useful for examining cost-effectiveness within the health and social care sectors, respectively, but there is a policy need to understand overall benefits and compare across sectors to assess relative value for money. Standard statistical mapping is unsuitable since it relies on conceptual overlap of the measures but EQ-5D and ASCOT have different conceptualisations of quality of life...
