There are limited data on the efficacy of procedures for adapting rodents to restraint in nose-only holders. We examined: (1) What effect does restraint in nose-only holders have on heart rate and body temperature? (2) Does a gradual increase in the duration of restraint facilitate adaptation? (3) How long does it take for rodents to become fully adapted to nose-only holders? (4) Do rats and mice respond and adapt similarly to restraint in nose only holders? Heart rate and body temperature were monitored as measures of stress using electrocardiograph (ECG) transmitters in male C57Bl/6J mice and Sprague-Dawley rats. In naive animals during the first hour of restraint, heart rate increased by 58 beats per minute (BPM) (18.6%) in rats and by 174 BPM (32.3%) in mice as compared to cage controls. Temperature increased by 2 degrees C in mice and was unchanged in rats compared to cage controls. Heart rate and temperature values remained within normal physiologic values during restraint. In rats, the response to restraint in nose-only holders was the same after 4 days regardless of whether the duration of restraint was increased gradually to 4 h/day or kept constant at 4 h/day. In mice, the group that was gradually adapted had a statistically significant higher heart rate and temperature after 4 days than the fixed-duration adapted group. Rats and mice restrained for 4 h/day every day showed a gradual decrease in heart rate and temperature over time. Full adaptation to restraint required 14 days of fixed-duration daily restraint.
BACKGROUND: This report offers a unique analysis of the psychological distress associated with ovarian cancer in a review of natural correspondence between ovarian cancer survivors and an ovarian cancer newsletter. METHODS: A review of 21,806 letters, cards, and e-mails reflecting correspondence from January 1994 to December 2000 between ovarian cancer survivors and the founding editor of Conversations!: The International Newsletter for those Fighting Ovarian Cancer was performed using ethnographic qualitative research methods. Statements related to the impact of disease were bracketed and coded within physical, psychological, social, and spiritual domains according to the City of Hope Quality of Life Ovarian Cancer instrument. Statements that reflected psychological well being were then evaluated with respect to the disease trajectory (i.e., diagnosis, treatment, remission, recurrence, and advanced disease/end of life). RESULTS: A total of 1282 communications were identified that pertained to psychological well being. Findings based on major themes derived from the analysis included descriptions of stressors associated with disease status. Significant stressors were identified within all phases of diagnosis, treatment, remission, and recurrence. Women described both positive and negative effects of disease and frequently demonstrated resourcefulness and perseverance by sharing coping mechanisms and survival strategies. CONCLUSIONS: The natural correspondence from women with ovarian cancer provided a rare opportunity to capture the psychological concerns of women throughout all stages of the cancer trajectory. Health care professionals' awareness of the common psychological stressors throughout the ovarian cancer trajectory may allow them to identify more readily the needs for support, leading to improvement in overall quality of life.
PURPOSE: The primary purpose of this prospective study was to identify the level of risk for psychosocial distress in families of children newly diagnosed with cancer. Additional study aims were to examine concordance among family and staff reports of psychosocial risk, changes in risk status over time, and to predict the use of psychosocial resources during the first months of treatment. PATIENTS AND METHODS: Caregivers of 125 children newly diagnosed with cancer completed the Psychosocial Assessment Tool (PAT) at diagnosis (t1) and 3 to 6 months later (t2). Primary oncologists and nurses completed an analogous measure of perceived family psychosocial risk at t1 and t2. At t2, oncology social workers reported types and intensity of psychosocial interventions provided. RESULTS: The PAT identified three subsets of families who presented with increasing levels of psychosocial risk at diagnosis. In general, there was moderate concordance among family, oncologist, and nurse reports of psychosocial risk. PAT scores at t1 predicted t2 PAT scores and psychosocial resource use at t2 beyond demographic or disease factors. CONCLUSION: A brief screening tool (PAT) is valuable in identifying psychosocial risk factors at diagnosis and is predictive of later use of psychosocial resources. As a next step in this research, the development of psychosocial interventions to match family risk level may be an effective and cost-efficient approach to working with families to address their concerns and promote short- and long-term adjustment.
