Fatigue in breast cancer survivors: occurrence, correlates, and impact on quality of life.

PURPOSE To describe the occurrence of fatigue in a large sample of breast cancer survivors relative to general population norms and to identify demographic, medical, and psychosocial characteristics of fatigued survivors. PATIENTS AND METHODS Breast cancer survivors in two large metropolitan areas completed standardized questionnaires as part of a survey study, including the RAND 36-item Health Survey, Center for Epidemiological Studies-Depression Scale, Breast Cancer Prevention Trial Symptom Checklist, Medical Outcomes Study Sleep Scale, and demographic and treatment-related measures. RESULTS On average, the level of fatigue reported by the breast cancer survivors surveyed (N = 1,957) was comparable to that of age-matched women in the general population, although the breast cancer survivors were somewhat more fatigued than a more demographically similar reference group. Approximately one third of the breast cancer survivors assessed reported more severe fatigue, which was associated with significantly higher levels of depression, pain, and sleep disturbance. In addition, fatigued women were more bothered by menopausal symptoms and were somewhat more likely to have received chemotherapy (with or without radiation therapy) than nonfatigued women. In multivariate analyses, depression and pain emerged as the strongest predictors of fatigue. CONCLUSION Although the majority of breast cancer survivors in this large and diverse sample did not experience heightened levels of fatigue relative to women in the general population, there was a subgroup of survivors who did report more severe and persistent fatigue. We identified characteristics of these women that may be helpful in elucidating the mechanisms underlying fatigue in this population, as well as directing intervention efforts.

Predictors of Sexual Health in Women After a Breast Cancer Diagnosis

PURPOSE To identify variables that might be predictive of sexual health (interest, dysfunction, and satisfaction) in a large sample of breast cancer survivors, with a validation conducted in a second, independent sample. PATIENTS AND METHODS On the basis of a conceptual framework of sexual health in breast cancer survivors, we performed multivariable regression analyses to estimate sexual interest, dysfunction, and satisfaction in both samples. Additional analyses were performed using stepwise regression and recursive partitioning to explore in each sample the relative contributions of the independent variables toward predicting the outcome measures. RESULTS The models for sexual interest accounted for at least 33% of the variance, and the significant predictors common to the two samples were having a new partner since the diagnosis of breast cancer, mental health score, and body image score. For sexual dysfunction, the models in the two samples explained at least 33% of the variance, and the common significant predictors were vaginal dryness, past chemotherapy use, and having a new partner since diagnosis. The sexual satisfaction models explained at least 27% of the variance, with the common significant predictors being the quality of the partnered relationship and sexual problems in the partner. CONCLUSION Among the predictors of sexual health, several are mutable (vaginal dryness, emotional well-being, body image, the quality of the partnered relationship, and sexual problems in the partner), and these should be considered for future interventions to address the sexual health and well-being of breast cancer survivors.

D2 and D4 dopamine receptor polymorphisms and personality

The relationship of various dimensions of temperament, measured by the Tridimensional Personality Questionnaire (TPQ), to polymorphisms of the D2 dopamine receptor (DRD2) and D4 dopamine receptor (DRD4) genes was determined in 119 healthy Caucasian boys who had not yet begun to consume alcohol and other drugs of abuse. Total Novelty Seeking score of the TPQ was significantly higher in boys having, in common, all three minor (A1, B1, and Intron 6 1) alleles of the DRD2 compared to boys without any of these alleles. Boys with the DRD4 7 repeat (7R) allele also had a significantly higher Novelty Seeking score than those without this allele. However, the greatest difference in Novelty Seeking score was found when boys having all three minor DRD2 alleles and the DRD4 7R allele were contrasted to those without any of these alleles. Neither the DRD2 nor the DRD4 polymorphisms differentiated total Harm Avoidance score. Whereas subjects having all three minor DRD2 alleles had a significantly higher Reward Dependence 2 (Persistence) score than subjects without any of these alleles, no significant difference in this personality score was found between subjects with and without the DRD4 7R allele. In conclusion, DRD2 and DRD4 polymorphisms individually associate with Novelty Seeking behavior. However, the combined DRD2 and DRD4 polymorphisms contribute more markedly to this behavior than when these two gene polymorphisms are individually considered.

Decreased anterior cingulate myo-inositol/creatine spectroscopy resonance with lithium treatment in children with bipolar disorder.

This project was designed to compare differences in brain proton spectra between children and adolescents with bipolar disorder (BPD) and gender and age-matched normal controls, and to measure changes in myo-inositol levels following lithium therapy, utilizing in vivo proton magnetic resonance spectroscopy (1H MRS). A single voxel (2x2x2 cm3) was placed in brain anterior cingulate cortex for acquisition of the 1H spectra at baseline and after acute (∼7 days) lithium administration in 11 children (mean age 11.4 years) diagnosed with BPD, and in 11 normal controls. Acute lithium treatment was associated with a significant reduction in the myo-inositol/creatine ratio. This decrement was also significant in lithium-responders when analyzed separate from non-responders. Compared to normal controls, BPD subjects showed a trend towards a higher myo-inositol/creatine during the manic phase. These preliminary data provide evidence that a significant reduction in anterior cingulate myo-inositol magnetic resonance may occur after lithium treatment, especially among responders. Follow-up studies involving a larger sample may allow us to confirm whether changes in myo-inositol associated with acute lithium therapy persist in long-term clinical response of patients with and without lithium compliance.

Behavior Problems, Academic Skill Delays and School Failure Among School-Aged Children in Foster Care: Their Relationship to Placement Characteristics

We describe the level of behavior problems, academic skill delays, and school failure among school-aged children in foster care. We also examine how behavior problems are associated with academic problems, and explore how these outcomes are related to childrens placement characteristics. Foster parent and child home interviews, as well as teacher telephone interviews were conducted from a randomly selected sample of 302 children aged 6 through 12 years living in out-of-home placement. Interviews included standardized screening measures. Results showed that 27% of the children scored in the clinical range for a behavior problem, and 34% were rated as having at least one behavior problem in the classroom. Twenty-three percent of the children had severe delays in reading or math, 13% had repeated a grade, and 14% had a history of school suspension and/or expulsion. Behavior problems by foster parent report were related to child suspension and/or expulsion from school, but were not associated with severe academic delays or grade retention. Placement characteristics were only sometimes related to these outcomes. Future studies examining the mental health and educational needs of this population should take into account the childs sociodemographic and placement characteristics.

Outcomes From the Moving Beyond Cancer Psychoeducational, Randomized, Controlled Trial With Breast Cancer Patients

PURPOSE Evidence suggests that the re-entry phase (ie, early period after medical treatment completion) presents distinct challenges for cancer patients. To facilitate the transition to recovery, we conducted the Moving Beyond Cancer (MBC) trial, a multisite, randomized, controlled trial of psychoeducational interventions for breast cancer patients. METHODS Breast cancer patients were registered within 6 weeks after surgery. After medical treatment, they completed baseline measures and were randomly assigned to standard National Cancer Institute print material (CTL); standard print material and peer-modeling videotape (VID); or standard print material, videotape, two sessions with a trained cancer educator, and informational workbook (EDU). Two primary end points were examined: energy/fatigue and cancer-specific distress. Secondary end points were depressive symptoms and post-traumatic growth. Perceived preparedness for re-entry was analyzed as a moderator of effects. RESULTS Of 558 women randomly assigned to treatment, 418 completed the 6-month assessment and 399 completed the 12-month assessment. In analyses controlling for study site and baseline depressive symptoms, VID produced significant improvement in energy/fatigue at 6 months relative to CTL, particularly among women who felt less prepared for re-entry at baseline. No significant main effect of the interventions emerged on cancer-specific distress, but EDU prompted greater reduction in this outcome relative to CTL at 6 months for patients who felt more prepared for re-entry. Between-group differences in the primary outcomes were not significant at 12 months, and no significant effects emerged on the secondary end points. CONCLUSION A peer-modeling videotape can accelerate the recovery of energy during the re-entry phase in women treated for breast cancer, particularly among those who feel less prepared for re-entry.

Inflammatory Biomarkers and Fatigue during Radiation Therapy for Breast and Prostate Cancer

Purpose: Biomarkers of radiation-induced behavioral symptoms, such as fatigue, have not been identified. Studies linking inflammatory processes to fatigue in cancer survivors led us to test the hypothesis that activation of the proinflammatory cytokine network is associated with fatigue symptoms during radiation therapy for breast and prostate cancer. Experimental Design: Individuals with early-stage breast (n = 28) and prostate cancer (n= 20) completed questionnaires and provided blood samples for determination of serum levels of interleukin 1β (IL-1β) and IL-6 at assessments conducted before, during, and after a course of radiation therapy. Serum markers of proinflammatory cytokine activity, including IL-1 receptor antagonist and C-reactive protein, were examined in a subset of participants. Random coefficient models were used to evaluate the association between changes in cytokine levels and fatigue. Results: As expected, there was a significant increase in fatigue during radiation treatment. Changes in serum levels of inflammatory markers C-reactive protein and IL-1 receptor antagonist were positively associated with increases in fatigue symptoms (Ps < 0.05), although serum levels of IL-1β and IL-6 were not associated with fatigue. These effects remained significant (Ps < 0.05) in analyses controlling for potential biobehavioral confounding factors, including age, body mass index, hormone therapy, depression, and sleep disturbance. Conclusions: Results suggest that activation of the proinflammatory cytokine network and associated increases in downstream biomarkers of proinflammatory cytokine activity are associated with fatigue during radiation therapy for breast and prostate cancer.(Clin Cancer Res 2009;15(17):5534–40)

Physical and Psychosocial Recovery in the Year After Primary Treatment of Breast Cancer

PURPOSE The 2000 National Institutes of Health Consensus Conference on Adjuvant Therapy of Breast Cancer recommended chemotherapy for all women with invasive cancer greater than 1 centimeter. Studies of long-term breast cancer survivors have found poorer quality of life (QOL) in women who received adjuvant chemotherapy. The aim of this article is to characterize physical and psychosocial recovery as a function of chemotherapy receipt in the year after medical treatment completion. PATIENTS AND METHODS Prospective longitudinal survey data (RAND SF-36 and Breast Cancer Prevention Trial [BCPT] Symptom Scales) collected from 558 women with breast cancer enrolled on the Moving Beyond Cancer (MBC) psychoeducational intervention trial were compared according to receipt of chemotherapy. MBC study enrollment occurred within 4 weeks after the end of primary treatment (eg, surgery, chemotherapy, radiation). Self-report questionnaire data collected at enrollment and at 2, 6, and 12 months thereafter were examined, controlling for intervention and with propensity score adjustment for imbalance of covariates. Outcome analyses were carried out by fitting linear mixed models by using SAS PROC MIXED. RESULTS Longitudinal SF-36 scale scores did not differ by chemotherapy treatment exposure, and both groups improved significantly (P < .01) in the year after primary treatment ended. However, adjuvant chemotherapy treatment was associated with significantly more severe physical symptoms, including musculoskeletal pain (P = .01), vaginal problems (P < .01), weight problems (P = .01), and nausea (P = .03). CONCLUSION Physical and psychosocial functioning improved significantly after breast cancer treatment, independent of receipt of adjuvant chemotherapy. Women who received chemotherapy experienced more severe and persistent physical symptoms that should be more effectively managed as part of survivorship care.

The 18-month impact of an emergency room intervention for adolescent female suicide attempters.

Following a suicide attempt by female adolescents, the impact of a specialized emergency room (ER) care intervention was evaluated over the subsequent 18 months. Using a quasi-experimental design, this study assigned 140 female adolescent suicide attempters (SA), ages 12-18 years, and their mothers (88% Hispanic) to receive during their ER visit either: (a) specialized ER care aimed at enhancing adherence to outpatient therapy by providing a soap opera video regarding suicidality, a family therapy session, and staff training; or (b) standard ER care. The adjustment of the SA and their mothers was evaluated over 18 months (follow-up, 92%) using linear mixed model regression analyses. SAs adjustment improved over time on most mental health indices. Rates of suicide reattempts (12.4%) and suicidal reideation (29.8%) were lower than anticipated and similar across ER conditions. The specialized ER care condition was associated with significantly lower depression scores by the SA and lower maternal ratings on family cohesion. Significant interactions of intervention condition with the SAs initial level of psychiatric symptomatology indicated that the interventions impact was greatest on maternal emotional distress and family cohesion among SA who were highly symptomatic. SAs attendance at therapy sessions following the ER visit was significantly associated with only one outcome--family adaptability. Specialized ER interventions may have substantial and sustained impact over time, particularly for the parents of youth with high psychiatric symptomatology.

A randomized trial of medical care with and without physical therapy and chiropractic care with and without physical modalities for patients with low back pain: 6-Month follow-up outcomes from the UCLA low back pain study

Study Design. A randomized clinical trial. Objectives. To compare the effectiveness of medical and chiropractic care for low back pain patients in managed care; to assess the effectiveness of physical therapy among medical patients; and to assess the effectiveness of physical modalities among chiropractic patients. Summary of Background Data. Despite the burden that low back pain places on patients, providers, and society, the relative effectiveness of common treatment strategies offered in managed care is unknown. Methods. Low back pain patients presenting to a large managed care facility from October 30, 1995, through November 9, 1998, were randomly assigned in a balanced design to medical care with and without physical therapy and to chiropractic care with and without physical modalities. The primary outcome variables are average and most severe low back pain intensity in the past week, assessed with 0 to 10 numerical rating scales, and low back-related disability, assessed with the 24-item Roland-Morris Disability Questionnaire. Results. Of 1,469 eligible patients, 681 were enrolled; 95.7% were followed through 6 months. The mean changes in low back pain intensity and disability of participants in the medical and chiropractic care-only groups were similar at each follow-up assessment (adjusted mean differences at 6 months for most severe pain, 0.27, 95% confidence interval, -0.32–0.86; average pain, 0.22, -0.25–0.69; and disability, 0.75, -0.29–1.79). Physical therapy yielded somewhat better 6-month disability outcomes than did medical care alone (1.26, 0.20–2.32). Conclusions. After 6 months of follow-up, chiropractic care and medical care for low back pain were comparable in their effectiveness. Physical therapy may be marginally more effective than medical care alone for reducing disability in some patients, but the possible benefit is small.
