Our results support the hypothesis that MRSA produces more severe bone infection and is likely to require more aggressive surgical and medical management.
BackgroundMercury is toxic to the developing brain, but the lowest concentration associated with the development of behavior problems is unclear. The purpose of this study was to examine the association between very low-level mercury exposure during fetal development and behavior problems in children.MethodsWe used data from 389 mothers and children in a prospective pregnancy and birth cohort study. We defined mean prenatal mercury concentration as the mean of total whole blood mercury concentrations in maternal samples collected at 16- and 26-weeks of gestation, delivery, and neonatal cord blood samples. We assessed parent-reported child behavior up to five times from two to 8 years of age using the Behavioral Assessment System for Children (BASC-2). At 8 years of age, we assessed self-reported child anxiety using the Spence Children’s Anxiety Scale (SCAS). We used multiple linear mixed models and linear regression models to estimate the association between mean prenatal mercury concentrations and child behavior and anxiety, respectively.ResultsThe median prenatal total blood mercury concentrations was 0.67 μg/L. Overall, we did not find statistically significant associations between mean prenatal mercury concentrations and behavior problems scores, but a 2-fold increase in mercury concentrations at 16-weeks gestation was associated with 0.83 point (95% CI: 0.05, 1.62) higher BASC-2 anxiety scores. Maternal and cord blood mercury concentrations at delivery were associated with parent-reported anxiety at 8 years.ConclusionWe found limited evidence of an association between very-low level prenatal mercury exposure and behaviors in children, with an exception of anxiety.
BackgroundTobacco use, alcohol use, and sugar-sweetened beverage consumption are each associated with increased cancer-risk. Psychological trauma is a common experience and a key driver of these behaviours among adults. The primary aim of this study is to evaluate the effect of trauma-informed yoga, drumming, and psychoeducation compared to control on tobacco use, alcohol use, and sugar-sweetened beverage consumption among community-based adults. Secondary aims are to evaluate the effect of these interventions compared to control on psychological and physiological stress symptomology, social connection, and coping behaviour.MethodsRecruitment for this single-blinded randomized trial began in April 2019 in the Faculty of Health Sciences at the University of Lethbridge. Adults who consumed tobacco, alcohol, or sugar-sweetened beverages in the past month and live in Lethbridge, Alberta are being recruited using ads placed in public spaces. Participants are randomly allocated to a 12-session group yoga class, 12-session group drumming class, a 12-session psychoeducation class, or control. Participants attend an appointment in-person to fill out an online questionnaire package, provide a saliva sample, and complete physical measures pre-intervention, and 1-month and 6-months post-intervention.DiscussionThis study provides a unique opportunity to compare the impacts of two trauma-informed body-based interventions to psychoeducation and control for cancer-risk behaviour among community-based adults. The findings can be used to develop trauma-informed group interventions to reduce cancer-risk behaviour in general populations. Results are expected in 2022.Trial registrationThis trial was registered with ClinicalTrials.gov ISRCTN15583681 on 22 August 2019 (retrospectively registered).
Background: Due to racism, xenophobic nationalism, acculturation pressures and patriarchal social relations, Asian men in Western societies may be particularly susceptible to negative experiences and beliefs regarding mental illness and treatment services. Aims: We examine factors associated with stigma toward mental illness among Asian men in Canada. Methods: Between 2013 and 2017, 428 self-identified Asian men living in proximity to Vancouver, Canada, were recruited and completed self-administered questionnaires assessing social stigma and self-stigma. The degree to which these variables were associated with the men’s sociodemographic characteristics was analyzed. Results: Multivariable regression revealed that social stigma was significantly predicted by age, immigration, employment status and experience with mental illness. Together, these variables accounted for 12.36% of variance in social stigma. Interaction terms were added to the regression models to examine whether the effects of immigration on social stigma varied by age and experience with mental illness, but none of the interaction terms were statistically significant. Among the 94 Asian men identified as living with mental illness, self-stigma was predicted by age, immigration and employment status, which together accounted for 14.97% of variance in self-stigma. Conclusion: These results offer new knowledge about the factors predicting stigma toward mental illness among Asian men in Western societies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
