Smoking related cancers: a brief report on problem solving, distress, and risk behaviors in patients and caregivers.

Cancer diagnoses may adversely affect emotional functioning in patients and their caregivers, which in turn may increase risk behaviors, such as tobacco and alcohol use. This study investigates the relationships among problem-solving ability, distress, and risk behaviors in patients with head/neck and lung cancer and their caregivers. The authors hypothesized that patients and caregivers who experienced higher distress would engage in more risk behaviors, but that Social Problem-Solving (SPS) would moderate this effect, in that those who possessed greater SPS ability would engage in fewer risk behaviors. Twenty-one cancer patients and 11 of their caregivers were surveyed shortly after diagnosis. Participants completed the Profile of Mood States, the Social Problem-Solving Inventory-Revised, and measures of tobacco and alcohol use. Total SPS ability was higher in patients than caregivers but generally low in both groups. Total distress was lower in patients compared to caregivers. Mean comparisons indicated that caregivers smoked more cigarettes per day and consumed more alcohol than patients. Results indicate that patients and caregivers may have a decreased ability to solve problems, and that caregivers engage in more frequent risk behaviors than patients, suggesting that caregivers may be at risk and warrant further study. The study design prevents causative conclusions and limited sample size prohibits more complex analyses. Further research on social problem-solving ability, distress, and risk behaviors may reveal more robust relationships and provide insight for intervention development for these groups.

College students' use of energy drinks, social problem-solving, and academic performance.

Energy drink (ED) use among college students to improve academic performance (AP) has skyrocketed. A growing body of literature indicates that the risks associated with ED use may outweigh the perceived benefits. In this study, 486 undergraduates were surveyed on their general substance and ED usage, Social Problem-Solving (SPS) ability, and AP. It was hypothesized that: (1) ED use would be a negative predictor of AP; (2) SPS would be a positive predictor of AP; (3) SPS would be a negative predictor of ED use; and (4) SPS and ED use would account for a significant amount of the variance in AP. A linear multiple regression for AP was conducted, with predictor variables entered in the following order: total drug use, non-ED caffeine use, SPS, and ED use. The overall model was significant and accounted for approximately 7% of the variance in AP. The hypotheses of the study were supported, indicating that ED use may be related to decreased AP, SPS ability may be related to increased AP, or that students with poor AP and less effective SPS skills are more likely to use EDs. Implications of these findings are important for college students and other users of ED products.

Home-based physical activity intervention for breast cancer patients.

PURPOSE: The efficacy of a home-based physical activity (PA) intervention for early-stage breast cancer patients was evaluated in a randomized controlled trial. PATIENTS AND METHODS: Eighty-six sedentary women (mean age, 53.14 years; standard deviation, 9.70 years) who had completed treatment for stage 0 to II breast cancer were randomly assigned to a PA or contact control group. Participants in the PA group received 12 weeks of PA counseling (based on the Transtheoretical Model) delivered via telephone, as well as weekly exercise tip sheets. Assessments were conducted at baseline, after treatment (12 weeks), and 6 and 9 month after baseline follow-ups. The post-treatment outcomes are reported here. RESULTS: Analyses showed that, after treatment, the PA group reported significantly more total minutes of PA, more minutes of moderate-intensity PA, and higher energy expenditure per week than controls. The PA group also out-performed controls on a field test of fitness. Changes in PA were not reflected in objective activity monitoring. The PA group was more likely than controls to progress in motivational readiness for PA and to meet PA guidelines. No significant group differences were found in body mass index and percent body fat. Post-treatment group comparisons revealed significant improvements in vigor and a reduction in fatigue in the PA group. There was a positive trend in intervention effects on overall mood and body esteem. CONCLUSION: The intervention successfully increased PA and improved fitness and specific aspects of psychological well-being among early-stage breast cancer patients. The success of a home-based PA intervention has important implications for promoting recovery in this population.

Body esteem and mood among sedentary and active breast cancer survivors.

OBJECTIVES: To assess mood states and body esteem in 2 groups of breast cancer survivors, regular exercisers and sedentary women, and to examine these variables among younger and older women in each group. PATIENTS AND METHODS: Between 1998 and 2002, we conducted a cross-sectional study among early-stage breast cancer survivors at the Miriam Hospital in Providence, RI, comparing 40 women who reported regular exercise with 79 sedentary women. We used multivariate and univariate analyses to compare the exercisers with sedentary women on fitness, physical activity, and questionnaire measures of body esteem and mood. Analyses were repeated after the 2 groups were subdivided by age (< 50 years vs > or = 50 years). RESULTS: Regular exercisers (mean +/- SD age, 54.57 +/- 9.18 years) reported significantly more positive attitudes toward their physical condition and sexual attractiveness; significantly less confusion, fatigue, depression, and total mood disturbance; and higher vigor than sedentary women (mean +/- SD age, 52.33 +/- 9.11 years). Both younger and older exercisers had higher physical condition scores than their sedentary peers. Older exercisers reported higher vigor and less confusion, anger, fatigue, depression, and total mood disturbance than sedentary women, regardless of age. Younger exercisers reported higher vigor than their sedentary peers and less confusion than older sedentary women. CONCLUSIONS: In this largely white sample of well-educated women, breast cancer survivors who exercised (particularly older women) reported higher body esteem and better mood than sedentary breast cancer survivors.

Social support as a mediator of optimism and distress in breast cancer survivors.

Breast cancer patients can experience emotional distress as a result of diagnosis and treatment. Higher levels of optimism and social support are associated with less emotional distress in cancer patients. This 12-month prospective study followed 69 women who had completed treatment for Stages 0-II breast cancer. At 3-month intervals, participants completed measures of mood disturbance, optimism, and social support. As hypothesized, affective social support mediated the relationship between optimism and distress in early-stage breast cancer survivors at baseline and 6 months but not at 1 year. In contrast, confidant social support did not mediate the optimism-distress relationship at any time point. Clinical and research implications of these findings are discussed.

Maintenance of effects of a home-based physical activity program among breast cancer survivors.

PURPOSE: Although physical activity (PA) adoption improves fitness and psychological well-being among cancer survivors, PA maintenance has not been examined. This paper presents follow-up of a home-based PA program for women treated for early-stage breast cancer. MATERIALS AND METHODS: Eighty-six sedentary women (mean age = 53.14 years, SD = 9.70) were randomly assigned to a PA or contact control group. The PA group received a 12-week telephone counseling program to adopt PA. Assessments were conducted at baseline, end-of-intervention (12 weeks), 6, and 9 months post-baseline. RESULTS: When comparing change from end-of-intervention (12 weeks) between groups, a significant reduction was observed in minutes of PA at 6 months (t = -2.10, p < 0.05), but there was no decrease in intervention effect at 9 months (t = -0.19, p = 0.84). Similarly, post-intervention reductions in fatigue were lost at 6 months (t = 3.27, p < 0.01), but remained present at 9 months (t = 1.65, p = 0.10). PA group's fitness improvements were maintained at both follow-ups (t = 1.04, p = 0.30 and t = 0.05, p = 0.96). The previously significant intervention effect on vigor was maintained at 6 months (t = 1.32, p = 0.19) but was significantly reduced at 9 months (t = -2.15, p < 0.05). PA participants were more likely to progress in motivational readiness at 6 (OR = 5.95, 95% CI = 2.30, 15.36) and 9 months (OR = 4.09, 95% CI = 1.69, 9.87); however, group differences in meeting PA guidelines were not maintained. CONCLUSION: Some positive effects of a home-based PA intervention for breast cancer patients were maintained at 6 and 9 months.

Physical activity among breast cancer survivors: regular exercisers vs participants in a physical activity intervention.

BACKGROUND: Secondary prevention is of great importance in the cancer survivor population, given the substantial medical risks survivors face. Consequently, researchers have begun developing interventions that target behavioral risk factors, such as sedentary lifestyle, among survivors. This study represents a novel approach for evaluating the efficacy of a physical activity intervention for breast cancer survivors. METHODS: Repeated measures analyses were used to compare a group of previously sedentary breast cancer survivors offered a physical activity intervention (n=43) with a group of regularly active survivors (n=40). These two groups were compared on select behavioral and psychosocial measures associated with physical activity. RESULTS: Results indicated significant time x group effects on the following: behavioral processes of change, minutes of moderate-intensity activity/week, and time to complete the one-mile walk test (a measure of fitness). There was also a borderline significant interaction for self-efficacy. Contrasts indicated that, for each interaction, previously sedentary and regularly active survivors differed at baseline, but were not significantly different postintervention. CONCLUSIONS: Thus, after completing a 12-week physical activity intervention, previously sedentary breast cancer survivors became similar to regularly active survivors on select behavioral and psychosocial measures associated with physical activity.

Cognitive dysfunction in advanced heart failure and prospective cardiac assist device patients.

BACKGROUND: Extended periods of hypoperfusion in an advanced heart failure (HF) places patients at high risk for neurobehavioral compromise, which has not been studied systematically. It is also not clear how intravenous inotropic therapy and mechanical cardiac assist devices (MCAD) affect cognitive function. METHODS: This prospective cross-sectional cognitive preliminary study evaluated 252 potential heart transplant candidates assessing functions in memory, motor, and processing speed. Patients were divided into three HF groups based on severity of disease: group 1 outpatients (n = 113), group 2 in-patients requiring inotropic infusion (n = 83), and group 3 inpatients likely requiring MCAD support (n = 56). Aggregate z-scores for memory, motor, and processing speed and independent samples t tests assessed intergroup differences on 13 cognitive measures. RESULTS: A broad pattern of cognitive impairment was observed within the advanced HF group; fewer deficits were found in group 1 outpatients and more severe deficits in group 3 MCAD subjects. A difference in motor functions was observed as the earliest abnormality, with group 3 showing significant changes compared with group 1. The most dramatic changes were seen in domain mental processing speed along with specific verbal and visual memory functions, which were slower in group 3 compared with groups 1 and 2. CONCLUSIONS: Cognitive deficits are common in advanced HF and worsen with increasing severity of HF. Appropriately designed and randomized studies will be needed to demonstrate if earlier MCAD implantation is warranted to arrest cognitive dysfunction and better postimplantation adaptation.

Health behaviors during and after a cancer diagnosis.

With improvements in cancer survival rates, more patients with cancer are living longer, and hence, cancer is becoming viewed as a chronic illness requiring long-term management. An important aspect of patient care during and after cancer treatment is patient health behaviors. For example, sequelae from various cancer treatments, such as chemotherapy and radiotherapy (RT), can compromise health in a variety ways, including decreased immune functioning, cardiotoxic effects of chemotherapy and/or RT, and weight gain. In addition, the stress caused by a cancer diagnosis and its treatment can disrupt existing health behaviors or exacerbate unhealthy behaviors. Continued smoking or alcohol use can complicate treatment and increase risk for further malignancy. Furthermore, decreased physical activity and poor nutrition can cause weight gain, which may contribute to secondary health problems such as cardiovascular disease and diabetes. The authors reviewed the extant literature on four key health behaviors among patients with cancer and survivors: healthy diet, reduced tobacco use, reduced alcohol use, and increased physical activity. They described the prevalence of these behaviors, reviewed the effects of interventions designed to alter unhealthy behaviors, and discussed the implications and future directions for this emerging area of research.

Exercise participation after diagnosis of breast cancer: trends and effects on mood and quality of life.

Individuals treated for cancer often experience higher levels of emotional distress than the general population. Previous research has shown that exercise can have an ameliorating effect on these problems. This 12-month prospective longitudinal study investigated mood, quality of life, cancer-related symptoms, and exercise behavior of 69 women who had completed treatment for Stage 0-2 breast cancer. We studied the natural progression of exercise participation after cancer treatment. Effects on mood, quality of life, and cancer-related symptoms were assessed after controlling for demographic variables, disease variables, social support, and baseline values to test the hypothesis that women who exercised were more likely to report better mood, higher quality of life, and fewer cancer-related symptoms. Results indicated that women did not increase their exercise participation over time and that overall mean minutes of exercise participation were below recommended levels. Baseline demographic predictors of exercise participation included younger age, having a spouse or partner, increased time since diagnosis, higher social support, and higher depression. Exercise participation was associated with improved physical functioning, but not overall mood or cancer-related symptoms. We discuss implications of these findings towards the well-being of breast cancer survivors.
