Introduction to the special issue: A festschrift for Janice Kiecolt-Glaser - At the origin of stress and immunity.

This special issue of pays tribute to Janice Kiecolt-Glaser's groundbreaking career and marks her well-earned retirement. As a leader in human psychoneuroimmunology (PNI), Kiecolt-Glaser transformed the domain by showing that everyday stressors, along with significant life events, can significantly affect the immune system. Her groundbreaking research on informal dementia caregivers revealed the detrimental effects of chronic psychological stress, including delayed wound healing, virus reactivation, heightened proinflammatory cytokine levels, and weakened vaccine responses.

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).

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.

Strain of the vertebral artery during passive neck movements and spinal manipulation of the cervical spine: An observational study.

Background: Neck pain is a common condition, and a frequent treatment is chiropractic cervical spinal manipulation therapy (cSMT). However, cervical spinal manipulations have been associated with excessive cervical artery elongations, allegedly causing arterial dissection leading to stroke.

Purpose: The primary purpose of this study was to quantify the total vertebral artery elongations during cSMT, and secondarily, quantify the vertebral artery elongations during the pre-manipulative orientation of the head and neck and the subsequent elongations during the actual thrust.
