Self-discrepancy and natural killer cell activity: immunological consequences of negative self-evaluation.

The study tested whether self-discrepancy theory could account for changes in natural killer (NK) cell activity after exposure to self-referential stimuli. Anxious, dysphoric, and control Ss were pretested and 1 month later covertly exposed to their own self-guides as well as those of another S. Blood samples were drawn for analysis of NK cytotoxicity and cortisol. The dysphoric Ss manifested the greatest actual:ideal discrepancy, whereas the anxious Ss manifested the greatest actual:ought discrepancy. Content analysis of written responses showed that activating discrepancies induced specific negative states; priming discrepancies also increased cortisol for the anxious Ss. NK activity was lower after self-referential priming for both distressed groups, particularly the anxious Ss. The control Ss showed a trend toward increased NK activity after self-referential priming. The study represents the 1st experimental demonstration that negative self-evaluation can alter immune responses.

Long-term biopsychosocial effects of interleukin-2 therapy.

This three-year project evaluates the biopsychosocial effects of interleukin-2 (IL-2) therapy on the first 45 patients treated with the therapy at the Moses Division of the Montefiore Medical Center in Bronx, NY, starting in April 1986. Therapy with IL-2 and lymphokine-activated killer (LAK) cells is a promising new development but requires an extensive amount of supportive care. Various important issues must be considered in planning the care of patients being treated with IL-2, including the effects of the treatment on quality of life, the cost of resources necessary for providing therapy, and the emotional effects of treatments. The instruments used to measure the various aspects of quality of life were the Sickness Impact Profile, the Inventory of Current Concerns, the Symptom Distress Scale, the Acute Physiology and Chronic Health Evaluation Scale, and the Therapeutic Intervention Scoring System. The researchers believe that, in addition to tumor response, the biopsychosocial and financial effects of treatment should be understood.

Testing hypotheses derived from the Roy Adaptation Model.

This study investigated the role of perception and biopsychosocial adaptation in patients with cancer entering an aggressive cancer treatment program. The Roy adaptation model provided the framework from which hypotheses were derived and tested. The hypotheses proposed that physiological stimuli are translated by the cognator through perception that alters the biopsychosocial responses. Forty-five patients were tested as they entered into the chemotherapy program. The APACHE II was used to measure actual physiological status; the Symptom Distress Profile was used to measure subjects' perceived physiological discomfort, and the Sickness Impact Profile was used to measure subjects' perceived effect of the cancer on their psychosocial adaptation. The results supported the theoretical predictions that perception of symptoms is positively correlated with psychosocial adaptation and not with actual physiological status. In addition, perception of symptoms and psychosocial adaptation were correlated with survival at six months and not with actual physiological status. Discussion of findings addresses theoretical and practice issues.

CA 125 levels in patients with ovarian carcinoma undergoing autologous bone marrow transplantation.

Levels of CA 125, determined in three patients with ovarian carcinoma undergoing autologous bone marrow transplantation, dropped significantly in the month after bone marrow transplantation. This decrease was linear by multiple regression analysis. The CA 125 decrease after bone marrow transplantation in patients with nonevaluable or stable disease may represent biologic response to high-dose therapy.
