- The ambulatory arterial stiffness index (AASI) is derived from 24-hour ambulatory blood pressure recordings. We investigated whether the goodness-of-fit of the AASI regression line in individual subjects (r(2)) impacts on the association of AASI with established determinants of the relation between diastolic and systolic blood pressures. We constructed the International Database on the Ambulatory Blood Pressure in Relation to Cardiovascular Outcomes (7604 participants from 6 countries). AASI was unity minus the regression slope of diastolic on systolic blood pressure in individual 24-hour ambulatory recordings. AASI correlated positively with age and 24-hour mean arterial pressure and negatively with body height and 24-hour heart rate. The single correlation coefficients and the mutually adjusted partial regression coefficients of AASI with age, height, 24-hour mean pressure, and 24-hour heart rate increased from the lowest to the highest quartile of r(2). These findings were consistent in dippers and nondippers (night:day ratio of systolic pressure >or=0.90), women and men, and in Europeans, Asians, and South Americans. The cumulative z score for the association of AASI with these determinants of the relation between diastolic and systolic blood pressures increased curvilinearly with r(2), with most of the improvement in the association occurring above the 20th percentile of r(2) (0.36). In conclusion, a better fit of the AASI regression line enhances the statistical power of analyses involving AASI as marker of arterial stiffness. An r(2) value of 0.36 might be a threshold in sensitivity analyses to improve the stratification of cardiovascular risk.

- In 30 survivors of childhood cancer, long-term psychological coping with experience of disease and treatment was studied in relation to factors associated with illness, treatment and demographic background. Coping was assessed in a prior study, in which three groups of varying levels of coping where delineated (good, 40%; intermediate, 33%; poor, 27%, coping). The present study showed that poor individual coping was related to diagnosis, a shorter time of continuous complete remission, more severe illness and treatment impairments, and lower scores on a test of intellectual abilities. In addition, a longer time of treatment tended to be followed by poorer coping. However, no association was found for gender, parents' occupational level, age at illness onset, neuro-cranial irradiation, irradiation dose (total) or age at investigation. A tentative path-analysis was executed, displaying a model for the relationships between medical and demographic background variables, and for their influence on coping. It was concluded that a complex of factors--associated particularly with severity of disease and treatment--appears to be related to, and affects, coping with the illness experience. Patients' long-term coping with their illness trauma is most likely determined by multiple factors. Intellectual capabilities are related to coping.

- Childhood cancer, although cured, may have long-term psychological consequences for the adult survivor. The outcome of patients' coping with the illness and treatment experience was assessed in relation to a theoretical model describing optimal long-term coping with a potential psychic trauma of this nature. Thirty young adult childhood cancer survivors were studied. The average age at diagnosis was 8 years, and at evaluation 22 years. The average time since diagnosis was 13 years. The evaluations of coping were carried out independently by two psychologists, who rated material from semistructured in-depth interviews. By statistical cluster analysis three clusters were produced that could be interpreted as exhibiting "good," "intermediate" and "poor" coping, containing 40, 33, and 27%, respectively, of the total group. Overall cluster differences were statistically significant. Profile analysis revealed statistical stability and internal homogeneity in the good coping cluster and the poor coping cluster.
