New Orleans English (NOE) has always stood out amongst Southern Englishes, since NOE speakers do not participate in the Southern vowel shift, and instead display features more commonly associated with New York City English. While these traditional features of NOE are on the decline, this study establishes the adoption of a new feature in the dialect that is similarly distinctive within the Gulf South: the pre-voiceless raising of the nucleus of /au/. Based on statistical analyses and consideration of the social context in post-Katrina New Orleans, this paper argues that this feature is a change in progress which appears to pre-date the demographic shifts following Hurricane Katrina, and which arose independently rather than due to contact with /au/-raising speakers. The social and phonetic findings in this paper converge to support arguments for the naturalness of raising in pre-voiceless environments, and for the likelihood of this feature being more widely adopted within the region. Moreover, the presence of Canadian raising of /au/ in NOE represents an additional way that the local dialect continues to diverge from patterns in the vowel systems found in nearby Southern dialects, and retain its uniqueness within the American South.

Background: Dementia is the seventh leading cause of death worldwide, impacting cognitive abilities and memory loss among aging populations. With the increasing prevalence of dementia, it is crucial to understand the distinct barriers and possibilities in providing care. Although there have been significant studies on dementia care, there is a lack of research that primarily focuses on the perspectives and worldviews of healthcare professionals, especially in the northern and rural regions of Ontario.

Social learning, where animals learn from other individuals, occurs in many diverse species. The influential but debated 'costly information' hypothesis posits that animals will rely more on social information in high-risk contexts, such as under increased predation risk. We examined and compared the effects of perceived predation risk on social learning of foraging sites in female Trinidadian guppies from wild and domestic populations raised in common-garden environments.

Background/objectives: Military aviators can be exposed to extreme physiological stressors, including decompression stress, G-forces, as well as intermittent hypoxia and/or hyperoxia, which may contribute to neurobiological dysfunction/damage. This study aimed to investigate the levels of neurological biomarkers in military aviators to assess the potential risk of long-term brain injury and neurodegeneration.
Methods: This cross-sectional study involved 48 Canadian Armed Forces (CAF) aviators and 48 non-aviator CAF controls.

Promising clinical evidence suggests that psychedelic compounds, like lysergic acid diethylamide (LSD), have therapeutic value for treatment of psychiatric disorders. However, they often produce hallucinations and dissociative states, likely mediated by the serotonin (5-HT) receptor 5-HT, raising challenges regarding therapeutic scalability. Given the reported antipsychotic effects of cannabidiol (CBD) and its promiscuous binding at many receptors, we assessed whether CBD could modulate 5-HT signaling.

Aims: To identify factors associated with use of novel diabetes medications among patients hospitalized under general internal medicine.
Methods: We conducted a cohort study of patients with type 2 diabetes mellitus (T2DM) hospitalized in Ontario, Canada between 2015 and 2020. We evaluated the patient- and physician-level factors associated with sodium-glucose cotransporter 2 inhibitor (SGLT2) and glucagon-like peptide 1 receptor agonist (GLP1R) use using a multivariable logistic regression model.
