RESUMEN

AIMS: To investigate the relationship between the framing of survival gains and the perceived value of cancer care. METHODS: Through a population-based survey of 2040 US adults, respondents were randomized to one of the two sets of hypothetical scenarios, each of which described the survival benefit for a new treatment as either an increase in median survival time (median survival), or an increase in the probability of survival for a given length of time (landmark survival). Each respondent was presented with two randomly selected scenarios with different prognosis and survival improvements, and asked about their willingness to pay (WTP) for the new treatments. RESULTS: Predicted WTP increased with survival benefits and respondents' income, regardless of how survival benefits were described. Framing therapeutic benefits as improvements in landmark rather than median time survival increased the proportion of the population willing to pay for that gain by 11-35%, and the mean WTP amount by 42-72% in the scenarios we compared. CONCLUSION: How survival benefits are described may influence the value people place on cancer care.

RESUMEN

OBJECTIVE: Numerous studies have shown a higher responsiveness and/or a lack of habituation to sensory stimuli of various modalities in migraine. This study investigated psychophysiological responses to aversive acoustic stimuli in children at risk for migraine. METHODS: We measured eyeblink responses to acoustic stimuli (40ms bursts of white noise at 102dB) during anticipation of unpleasant stimuli in 74 adolescents (40 females, age 17.6+/-2.9). A mixed effects linear model was applied to test group differences in startle reactivity during baseline, safe and threat conditions among adolescents by maternal and personal history of migraine. RESULTS: The strongest association with migraine vulnerability emerged for baseline startle reactivity, which was significantly elevated in high risk youth with a history of maternal migraine. This group of offspring also had enhanced startle response during the threat condition and the threat-safe difference. CONCLUSION: Our findings indicate that migraine is associated with a higher acoustic startle responsiveness that is present already in children at risk for developing the disorder. SIGNIFICANCE: The significant effect of both maternal history of anxiety disorder and migraine on baseline startle indicates that these two diagnostic entities might in part share common pathophysiological mechanisms, and that the anxiety-migraine comorbidity should be considered when investigating each of these disorders.

RESUMEN

BACKGROUND: Anxiety symptoms might be a vulnerability factor for the development of major depressive disorder (MDD). Because elevated startle magnitude in threatening contexts is a marker for anxiety disorder, the present study investigated the hypothesis that enhanced startle reactivity would also be found in children and grandchildren of individuals with MDD. METHODS: The magnitude of startle was investigated in two tests (anticipation of an unpleasant blast of air and during darkness) in children (second generation) and grandchildren (third generation) of probands with (high risk) or without (low risk) MDD (first generation). RESULTS: Startle discriminated between the low- and high-risk groups. In the probands' children, the high-risk group showed increased startle magnitude throughout the fear-potentiated startle test. In the probands' grandchildren, a gender-specific abnormality was found in the high-risk group with high-risk girls, but not boys, exhibiting elevated startle magnitude throughout the procedure. CONCLUSIONS: Increased startle reactivity in threatening contexts, previously found in patients with anxiety disorder and in children of parents with an anxiety disorder, might also constitute a vulnerability marker for MDD. These findings suggest that there might be common biologic diatheses underlying depression and anxiety.

RESUMEN

BACKGROUND: Electroencephalographic (EEG) studies have found abnormal regional hemispheric asymmetries in depressive disorders, which have been hypothesized to be vulnerability markers for depression. In a longitudinal high-risk study, resting EEG was measured in primarily adult offspring of depressed or nondepressed probands. METHODS: Electroencephalograms from12 homologous sites over each hemisphere (digitally linked-ears reference) were analyzed in right-handed offspring for whom both parents (n = 18), one parent (n = 40), or neither parent (n = 29) had a major depressive disorder (MDD). RESULTS: Offspring with both parents having MDD showed greater alpha asymmetry at medial sites, with relatively less activity (more alpha) over right central and parietal regions, compared with offspring having one or no parent with MDD. Relatively less left frontal activity at lateral sites was associated with lifetime MDD in offspring but not with parental MDD. Offspring with both parents having a MDD also showed markedly greater anterior-to- posterior increase in alpha with eyes closed compared with those with one or no parent with a MDD. CONCLUSIONS: Alpha asymmetry indicative of right parietotemporal hypoactivity, previously reported for depressed adolescents and adults, and heightened anterior-to-posterior gradient of alpha are present in high-risk offspring having parents concordant for MDD.
