1) To examine the relationship between migraine status and complete mental health (CMH) among a nationally representative sample of Canadians; 2) To identify significant correlates of CMH among those with migraine. Methods Secondary analysis of the nationally representative Canadian Community Health Survey – Mental Health (CCHS-MH) (N=21,108). Bivariate analyses and a series of logistic regression… Continue reading Flourishing Despite #Migraines: A Nationally Representative Portrait of Resilience and Mental Health among Canadians

#Perception of invisible masked objects in early infancy
Recurrent loops in the visual cortex play a critical role in visual perception, which is likely not mediated by purely feed-forward pathways. However, the development of recurrent loops is poorly understood. The role of recurrent processing has been studied using visual backward masking, a perceptual phenomenon in which a visual stimulus is rendered invisible by… Continue reading #Perception of invisible masked objects in early infancy
Adaptive circuit dynamics across human #cortex during evidence accumulation in changing #environments
Many decisions under uncertainty entail the temporal accumulation of evidence that informs about the state of the environment. When environments are subject to hidden changes in their state, maximizing accuracy and reward requires non-linear accumulation of evidence. How this adaptive, non-linear computation is realized in the brain is unknown. We analyzed human behavior and cortical… Continue reading Adaptive circuit dynamics across human #cortex during evidence accumulation in changing #environments
The risk of ischemic #stroke and hemorrhagic stroke in Chinese adults with low-density lipoprotein #cholesterol concentrations < 70 mg/dL
The risk of stroke in individuals with very low low-density lipoprotein cholesterol (LDL-C) concentrations remains high. We sought to prioritize predictive risk factors for stroke in Chinese participants with LDL-C concentrations < 70 mg/dL using a survival conditional inference tree, a machine learning method. MethodsThe training dataset included 9327 individuals with LDL-C concentrations < 70 mg/dL who were free… Continue reading The risk of ischemic #stroke and hemorrhagic stroke in Chinese adults with low-density lipoprotein #cholesterol concentrations < 70 mg/dL
#Mineralocorticoid receptors dampen glucocorticoid receptor sensitivity to #stress via regulation of FKBP5
Responding to different dynamic levels of stress is critical for mammalian survival. Disruption of mineralocorticoid receptor (MR) and glucocorticoid receptor (GR) signaling is proposed to underlie hypothalamic-pituitary-adrenal (HPA) axis dysregulation observed in stress-related psychiatric disorders. In this study, we show that FK506-binding protein 51 (FKBP5) plays a critical role in fine-tuning MR:GR balance in the… Continue reading #Mineralocorticoid receptors dampen glucocorticoid receptor sensitivity to #stress via regulation of FKBP5
#Thyroid Hormone Therapy and Incident #Stroke
Stroke is a leading cause of death and disability and there is a need to identify modifiable risk factors. ObjectiveDetermine the relationship between thyroid hormone treatment intensity and incidence of atrial fibrillation and stroke. DesignRetrospective cohort study using data from the Veterans Health Administration between 2004 and 2017, with a median follow-up of 59 months.… Continue reading #Thyroid Hormone Therapy and Incident #Stroke
Effect of #bariatric surgery on ischemic #stroke risk
Bariatric surgery has demonstrated improvements in cardiovascular health. The effect on ischemic stroke risk remains unclear. The goal of this study was to compare the risk of stroke among bariatric surgery patients versus controls. MethodsUsing Mariner, a national all-payer claims database, we identified patients with BMI > 40, or BMI > 35 with qualifying comorbidities… Continue reading Effect of #bariatric surgery on ischemic #stroke risk
Factors associated with #eating performance in older adults with #dementia in long-term care facilities: a cross-sectional study
The purpose of this study was to investigate factors influencing eating performance in older adults with dementia (OAWDs) in long-term care (LTC) facilities. MethodsThis cross-sectional study examined risk factors for compromised eating performance by comparing both independent and dependent older adults with dementia. The study participants were 117 OAWDs in LTC facilities in South Korea.… Continue reading Factors associated with #eating performance in older adults with #dementia in long-term care facilities: a cross-sectional study
Reduced adaptation of glutamatergic #stress response is associated with #pessimistic expectations in #depression
Stress is a significant risk factor for the development of major depressive disorder (MDD), yet the underlying mechanisms remain unclear. Preclinically, adaptive and maladaptive stress-induced changes in glutamatergic function have been observed in the medial prefrontal cortex (mPFC). Here, we examine stress-induced changes in human mPFC glutamate using magnetic resonance spectroscopy (MRS) in two healthy… Continue reading Reduced adaptation of glutamatergic #stress response is associated with #pessimistic expectations in #depression
