Can a reminiscing intervention alter depression and self-esteem?

This study assessed the value of reminiscing as a therapeutic intervention for older persons. A decrease in depression and an increase in self-esteem were the hypothesized outcomes. Twenty-one community residents, mean age seventy-seven years, were randomly assigned to one of three groups: the first group was involved in structured reminiscing for forty-five minutes during each of five weeks; the second group was a control that focused on current life events; and the third group was a no-treatment control. Analysis of changes from pretest to posttest revealed no significant differences for either depression or self-esteem. This study provides no support for claims that reminiscing can be an effective short-term therapeutic intervention.

Sex differences in perceptions of aging.

This study extends earlier work on perceptions of aging by assessing sex differences and by focusing on specific events of aging, rather than global perceptions. Thirty persons over sixty-five years were asked individually to rate the difficulty of sixteen events for themselves, other women, and other men. The general finding of previous studies that difficulty for oneself is not as great as for others was replicated. Also, there was no difference in the difficulty overall for men and women. However, both these findings must be interpreted in the light of a significant (p less than .01) interaction between sex of other person and specific events. Change in appearance, departure of children, and decrease in time with children are seen as more difficult for other women. Increased leisure time, decreased strength, and retirement are seen as more difficult for other men. Statements regarding difficulty of aging ought to be precise to as sex and specific events of aging.

Improvement of human myocardial mitochondria after dobutamine: a quantitative ultrastructural study.

Dobutamine is a new inotropic agent that may induce prolonged clinical improvement in patients with congestive cardiomyopathy. Sixteen patients with severe heart failure but without obstructive coronary disease were studied by serial functional class determinations and by noninvasive measurements of left ventricular function before and after bedrest control period and then after a 3-day infusion of dobutamine. An endomyocardial biopsy procedure was performed on 11 patients before and after the bedrest and on all 16 patients before and after dobutamine. Quantitative ultrastructural analysis of the biopsies was performed on electron micrographs (31,200 X) by a grid technique. The number of electron dense particles per 100 mitochondria did not change after bedrest but there was a significant decrease from 84 +/- 14 to 65 +/- 12 (P < .005) in the pre- to postdobutamine biopsies. The cristae to matrix ratio of the mitochondria did not change with bedrest but improved from 0.37 +/- 0.04 to 0.47 +/- 0.05 (P < .02) after dobutamine. The average mitochondrial size did not change significantly in the bedrest control nor in the dobutamine biopsy samples. However, when the 16 patients were divided into those who had a good clinical response (by functional class and noninvasive measurements of left ventricular function) and those who had no or little response, the 10 responders did decrease their average mitochondria size from 0.26 +/- 0.03 mu 2 to 0.23 +/- 0.02 mu 2 (P < .02). The mechanism by which a 3-day infusion of dobutamine induces a prolonged clinical improvement is not well understood. The use of quantitative ultrastructural technique in this study has demonstrated that there is a morphologic basis to the improvement.

Formal aspects of theories of development.

The presentation of theories of adult development and aging in terms of their formal aspects can promote precision and clarity in theory construction, facilitate communication between subdisciplines of gerontology, provide a vehicle for the heuristic impact of theories and models upon each other, and alert older persons, practitioners, and researchers that there is a variety of models available for describing social and psychological changes. Theories may be categorized as simple or cumulative sequences, the latter permitting within-person response variation, and as disjunctive or conjunctive sequences, the latter implying the some characteristics are subordinate to others. These categories are illustrated with familiar examples from social, personality, and cognitive development, with particular attention given to the formal aspects of Erikson's theory.

Anxiety, prospective remembering, and performance of planned actions.

This study contrasted two models of prospective remembering: i.e., remembering in the future to perform an action that has been planned. High anxiety or discomfort is predicted by the first model to be associated with forgetting, and by the second model to be associated with remembering but not performing. Questionnaire data from 73 male and female college students support the second model (p < .01). For planned actions that were forgotten, there was an inverse relationship between importance and comfortableness (p < .01). Prospective remembering may be facilitated by reducing potential conflict between the importance and comfortableness of a planned action, involving other persons, and utilizing external retrieval cues.

Prolonged atrial conduction. A major predisposing factor for the development of atrial flutter.

Electrophysiological studies were performed during sinus rhythm on 21 patients who had demonstrated the spontaneous occurrence of sustained atrial flutter. The purpose was to determine if atrial conduction disease is a prediposing factor for the development of atrial flutter. Patients with atrial enlargement were excluded from the series. The control group consisted of 11 age-matched patients with normal electrocardiograms and electrophysiology studies. The flutter group showed prolongation of the mean right intra-atrial conduction time at 50 msec (control of 37 msec, P less than 0.05), the mean interatrial conduction time at 92 msec (control of 44 msec, P less than 0.001) and the mean P wave duration at 132 msec (control of 112 msec, P less than 0.01). The flutter group also demonstrated a higher incidence of sinus node dysfunction and ventricular conduction disease compared to the control group. These data indicate that patients who develop atrial flutter have atrial conduction disease. Atrial conduction disease appears to be 1) a major prediposing factor for the development of atrial flutter and 2) a part of the fibro-degenerative conduction disease spectrum.
