Parenting stress in pediatric oncology populations.

The experience of childhood cancer can be one of the most severe stressors that parents endure. Studies using illness-specific measures of parental stress indicate that moderate-to-severe parenting stress is quite common in the first year of childhood cancer treatment, and as many as 5% to 10% of these parents go on to develop posttraumatic stress disorder. This review of the literature suggested that although parenting stress symptoms may be relatively transitory for most parents dealing with childhood cancer, the impact of these stress symptoms on parent and child functioning is substantive and worthy of therapeutic attention.

Interactive effects of anger expression and ET-1 Lys198Asn polymorphism on vasoconstriction reactivity to behavioral stress.

Background: Ineffective anger expression has been associated with essential hypertension (EH) and with blood pressure (BP) reactivity to stress. The ET-1/Lys198Asn polymorphism has been associated with increased resting BP and exaggerated vasoconstrictive mediated BP reactivity. African Americans (AAs) are at particular risk for development of EH, report greater anger difficulties, and exhibit greater vasoconstrictive reactivity than their European American (EA) counterparts.
