Memory complaint and performance in normal and depressed older adults.
The present study investigated the influence of depression on memory complaints and performance in a sample of community dwelling older adults (N = 41). Complaints were significantly more frequent in the clinically depressed subsample. However, their actual performance on tests of immediate and delayed recall did not differ significantly from the performance of nondepressed older adults. In addition, results indicated that depressives who responded favorably to a program of psychotherapy demonstrated significant reductions in levels of memory complaints at post-treatment assessment. Implications of these data for further research are discussed.

Psychosocial factors affecting adaptation to bereavement in the elderly.
A spouse's death requires more readjustment on the part of the bereaved than any other stressful life event. This finding holds across the many age groups and cultural backgrounds that have been studied. Although it is unclear as to whether the stress of bereavement is greater for women than for men, for the young than for the old, for one socioeconomic level or for another, a critical review of the literatures suggests the following: 1) Negative changes in physical health, mortality rate and mental health status usually accompany widowhood; 2) Complex social-psychological variables such as the individual's characteristic ways of coping with stress (coping strength), the adequacy of the social network - plus other factors such as income and religious commitment - may attenuate widowhood's negative impact. Suggestions for further research include studies exploring differential adaptation to widowhood across age groups and in elderly men and women, and longitudinal studies tracing the process of recovery from acute grief.

Screening for prostate cancer: is ultrasound the answer?
The high incidence and subsequent mortality from prostate cancer in progressively older US males is a serious health concern. Prognosis is related to extent of spread of the disease at the time of diagnosis and to pathologic grading of the tumor cells. The argument for early detection is somewhat clouded by a high incidence of latent prostate cancer related to increasing age, which may or may not progress to clinical disease. Recent applications of ultrasound technology have greatly improved our ability to image the prostate gland and raised the possibility of using ultrasound to screen for prostate cancer. The conclusions of this investigation are that ultrasound should not yet replace annual digital rectal examination as the primary screening tool, but ultrasound is a useful diagnostic adjunct. This recommendation may change with further application of the technology and as more information is gathered.
