Coping with cancer during the first year after diagnosis. Assessment and intervention.

The emotional coping of 205 patients newly diagnosed with cancer was evaluated every 4 months during a 1-year period. Patients received a psychosocial intervention either immediately (early intervention, EI), or after a 4-month delay (later intervention, LI). No significant differences were found between the two groups, except at 8 months, when the LI group was significantly less depressed, anxious, and worried, and felt more in control than the EI group. The LI group continued to have less worry related to illness at 12 months. Patients with high ego strength had low levels of distress at baseline and may not have needed the intervention. The emotional coping of patients with breast cancer improved during the year regardless of the intervention timing. Patients with other diagnoses appeared to benefit most from the IL. It was concluded that patients with low ego strength and diagnoses other than breast cancer might be at higher risk for psychosocial complications and could benefit from the intervention.

Adaptation, Psychological

A survey examining nurses' knowledge of pain control.

Three hundred and eighteen (318) nursing staff members at an acute care teaching hospital in Montreal, Canada, were surveyed to identify their knowledge of pain assessment and management. Two pain instruments were combined and adapted for use. The final instrument consisted primarily of true/false responses and took about 10 min to complete. The mean score was 63.9%. Overall results indicated that nurses lacked knowledge and understanding of opioid addiction, equivalent dosing, properties of opioids, and differences in acute and chronic pain. No statistically significant differences were found in the scores by level of educational preparation or by years of experience. Presentation of the results unit by unit demonstrated that the instrument is suitable as an educational tool as well as an effective strategy to introduce nursing staff to nursing research.

Adult

[Psychosocial intervention for persons infected with HIV].

We describe a psychosocial intervention program designed to enhance coping with the stress associated with HIV infection. The NUCARE intervention program is based on six components of coping including: cognitive reframing, problem-solving, relaxation, goal setting, social support and use of resources and services. The rationale and development of the intervention is discussed and practical case examples illustrating the benefits of each component are presented.

Adaptation, Psychological

Reversible alteration in the neuromuscular junctions of Drosophila melanogaster bearing a temperature-sensitive mutation, shibire.

In this study we report a relationship between the ultrastruct of the neuromuscular junctions of tibial muscles and the temperature-induced paralysis in shibire flies. There is a decrease in the number of synaptic vesicles of neuromuscular junctions in flies which are held at or above 29 degrees. Shortly after return to 22 degrees C, the synaptic vesicles are again present in large numbers. Prior treatment with tetrodotoxin or barbiturate protects the junctions from the temperature change in morphology.
