RESUMO
BACKGROUND: Little is known about the perceived stress level of Syrian Refugee (SR) parents residing in Canada specifically in relation to different sponsorship programs. This study aims to assess the relationship between the different sponsorship programs [Government-Assisted Refugees (GAR), Privately Sponsored Refugees (PSR) and Blended Visa Office-Referred refugees (BVOR)] and perceived stress among SR parents, with at least one child under the age of four, who resettled in the Greater Toronto area after 2015. METHODS: A convenience sample of 155 Syrian Refugee (SR) parents was recruited. Perceived levels of stress were measured using the Perceived Stress Scale (PSS-10). Multiple linear regression analysis was performed to assess the independent relation between several types of sponsorship programs and PSS adjusting for demographic, economic and social factors. RESULTS: The overall average PSS score was found to be 12.5 ± 7.2 with BVORs presenting the highest level of moderate stress when compared to GARs and PSRs (75.0% compared to 39.5% and 35.2% respectively). Multivariate analysis showed that the mean PSS was significantly higher among BVORs when compared with GARs (Adj ß = 4.8; 95% CI 0.4, 9.2). No significant difference in PSS levels was reported when PSRs were compered to GARs. Increased PSS scores were found to be associated with worse family functioning (Adj ß = 4.2; 95% CI 1.0, 7.4), while decreased PSS scores were associated with increased age (Adj ß = -0.4; 95% CI -0.6, -0.1). CONCLUSION: A better understanding of the various underlying factors associated with elevated stress is essential for improving the quality of life for SRs in Canada. Results of the study may help tailor more effective preventative measures or government interventions dedicated to reducing stress levels among this population.
RESUMO
A three-way crossover study in 27 human volunteers was conducted to characterize the pharmacokinetics and to assess the dose proportionality of 100 mg, 200 mg and 300 mg strengths of a novel once-a-day tramadol controlled-release tablet (Tramadol Contramid OAD) following single-dose administration. Serial blood samples were collected at predefined timepoints over a 48 h period and racemic tramadol and O-desmethyltramadol concentrations in plasma were determined using a validated LC-MS/MS method. Pharmacokinetic parameters were derived using noncompartmental methods. Following dose normalization and logarithmic transformation of concentration-dependent parameters, the results were compared using analysis of variance (ANOVA). The residual variability thereby obtained was used to construct 90% classical confidence intervals. The two one-sided tests procedure was used for all pairwise comparisons. Dose proportionality was concluded since the 90% CI for the ratio of geometric means was included in the acceptance range of 0.80-1.25 for all comparisons.
