Examining Bi-directional links between distinct affect states and tobacco lapse during a cessation attempt.

Background: Theoretical models of addiction highlight the bi-directional links of certain distinct affect states and tobacco lapse, but to date, few studies have examined bi-directional associations, instead examining associations with global affect measures (e.g., negative affect versus feelings of guilt).

Characterizing the Effect of Repetitive Head Impact Exposure and mTBI on Adolescent Collision Sports Players' Brain with Diffusion Magnetic Resonance Imaging.

Athletes in collision sports frequently sustain repetitive head impacts (RHI), which, while not individually severe enough for a clinical mild traumatic brain injury (mTBI) diagnosis, can compromise neuronal organization by transferring mechanical energy to the brain. Although numerous studies target athletes with mTBI, there is a lack of longitudinal research on young collision sport participants, highlighting an unaddressed concern regarding cumulative RHI effects on brain microstructures. Therefore, this study aimed to investigate the microstructural changes in the brains' of high school rugby players due to repeated head impacts and to establish a correlation between clinical symptoms, cumulative effects of RHI exposure, and changes in the brain's microstructure.

Momentary predictors of tobacco lapse among African Americans during a quit attempt.

Background And Aims: African American smokers are less likely to successfully quit and experience a greater burden of tobacco-related health outcomes than White individuals. There is a profound need to understand factors that impact tobacco cessation among African Americans who are undergoing a quit attempt. This study aimed to examine the within- and between-person associations of risk factors (motivation, self-efficacy, urge, positive affect, negative affect, smoking expectancies, and cigarette availability) with lapse.

Systematic review of what people know about brain health.

Objectives: As we age our cognitive abilities can change. However, the degree of change experienced is influenced by a range of factors. To understand what the public know about risk and protective factors for cognitive ageing, a systematic review was conducted of studies considering what people know about brain health.
