    ABSTRACT: Heart failure (HF) is a growing public health problem affecting approximately 23 million people worldwide. Treatment options for advanced HF patients have moved beyond pharmacologic therapy to include left-ventricular assist devices (LVADs). Patients with an LVAD must manage a complex regimen of care. This article proposes the use of self-care deficit nursing theory (SCDNT) as a framework to identify and organize the care needs of patients with an LVAD from a nursing perspective. Within SCDNT, self-care refers to actions designed to meet self-care requisites to achieve regulatory goals. When formalized, self-care requisites have two components: the general action to be taken and a "factor" to be controlled. The reformulation of health-deviation self-care requisites common to LVAD patients are presented and may serve as an exemplar for other technology-assisted living situations. The strengths and limitations of using the SCDNT for patients with such complex needs, as well as implications for clinical practice, research, and advancement of nursing science, are examined.

    ABSTRACT: To investigate whether quality of life (QOL) assessed before weight loss intervention predicts weight loss and, in turn, what the effect of weight loss is on QOL measures after 12 months in early-stage breast cancer survivors. A clinical trial of a weight loss intervention in breast cancer survivors. Community-wide recruitment in Detroit, MI. 39 breast cancer survivors (body mass index = 30-44 kg/m2), within three years of initial diagnosis and at least three months after chemotherapy or radiation therapy. Participants were randomized to one of three weight loss methods or a control group. The Functional Assessment of Cancer Therapy-Anemia (FACT-An) QOL questionnaire was administered at baseline and after the intervention. Six subscales of the FACT-An and weight change. Modest but statistically significant associations were found for the physical and functional subscales of the FACT-An with weight loss for 39 subjects who completed 12 months of the study. Those reporting relatively impaired physical or functional QOL at baseline lost more weight, which accounted for 8%-9% of the weight loss variance beyond that resulting from the diet arm assignment. At 12 months, greater weight loss was associated with significant improvements in overall FACT-An score and in the physical, functional, fatigue, and anemia subscales (p < 0.05). Relatively low physical function at baseline was not a barrier to weight loss; indeed, it may have been a motivating factor in adherence to the weight loss intervention. Weight loss was associated with improvement in several QOL subscale measures in breast cancer survivors, but the emotional and social subscales were not affected. Counseling for weight loss that includes recommendations for exercise should not be withheld for patients with relatively low physical functioning.

    ABSTRACT: It has been documented that social support influences health outcomes of persons with chronic illnesses. The incidence of HIV and AIDS among minority women is growing at an alarming rate, but little is known about social support in this vulnerable population, and even less is known about the social network conveying that support. Guided by the convoy of social networks model, this study describes the social networks in a sample of HIV-positive, urban-dwelling mothers (N = 147) by stage of disease (i.e., asymptomatic, symptomatic, AIDS) and examines relationships between social network structure and social support. Hierarchical linear modeling showed that women's social networks were disproportionately populated by children, and network members of women with AIDS were significantly older than network members of HIV-positive women with or without symptoms. Profile analyses showed that women's perceptions of the quality of social support differed according to the proportion of family members populating different segments of the social network.

    ABSTRACT: Obese breast cancer survivors are a unique population for weight loss counseling because both obesity and a diagnosis of breast cancer can increase the risk of depression. In this pilot study, weight loss maintenance was examined in obese breast cancer survivors with relationship to psychiatric diagnosis. Forty-eight subjects were enrolled. The intervention, which used individualized counseling for diet and exercise, lasted 24 months. After a 6-month period of no contact with study subjects, a follow-up body weight was obtained at 30 months. The nine subjects who dropped out of the study before 12 months all failed to complete a structured psychiatric interview. Of the remaining 39 subjects, 9 had major depressive disorder, and 10 had a definable psychiatric disorder of lesser severity such as adjustment disorder. Subjects with any type of psychiatric diagnosis displayed significantly less weight loss at the 12-month time-point than those with no diagnosis (6.3% vs. 12.6% loss of baseline weight, respectively). At the 30-month follow-up visit, subjects with any psychiatric disorder had a mean weight loss of 1.2% of baseline weight compared with 7.8% weight loss in subjects with no diagnosis. These results suggest that the presence of psychiatric disorders can interfere with weight loss. Therefore, recognition and treatment of psychiatric disorders may be important in attempts at weight reduction, and this will be especially important in populations such as cancer survivors, who seem to have higher rates of depression and other disorders than the general population.

    ABSTRACT: Positive health outcomes for heart failure (HF) patients depend on patient participation in the selection and use of appropriately focused heart failure self-care. To produce a system of heart failure self-care, patients must have an adequately developed fund of highly specialized antecedent knowledge. This research found that knowledge needed to produce heart failure self-care was deficient in a diverse sample of heart failure patients. Low levels of knowledge were especially evident in the areas of heart failure medications, weight monitoring, and being able to recognize the correct definition of heart failure. Although being older and being more highly educated were associated with higher levels of HF knowledge, HF knowledge scores were uniformly low across gender and racial groups. If nurses are going to be instrumental in helping heart failure patients achieve positive health outcomes, creative strategies to provide information and increase the knowledge necessary to produce HF self-care need to be developed and tested.

    ABSTRACT: One way to prevent frequent hospitalizations and promote positive health outcomes among patients with heart failure (HF) is to ensure that the amount and quality of self-care used is appropriate to the patient's situation. The following are the purposes of this study: (a) examine the frequency of performance of self-care behaviors, (b) describe personal and environmental factors (basic conditioning factors [BCFs]) that affect self-care behaviors, and (c) describe the relationship between the level of knowledge patients have to empower their performance of self-care and the actual performance of self-care behaviors. This descriptive correlational study was guided by Orem's theory of self-care. One hundred ten participants, predominantly African Americans, who were outpatients or inpatients ready for hospital discharge, 18 years or older, and diagnosed with HF that was confirmed by an ejection fraction of 40% or less were conveniently selected from 1 of 2 sites. Data were collected with 2 investigator-developed instruments: the Revised Heart Failure Self-Care Behavior Scale and the Heart Failure Knowledge Test. Descriptive statistics, correlational analyses, and t tests for independent samples were used to analyze the data. Three of the top 5 most frequently performed self-care behaviors were related to taking prescribed medications, and the 5 least frequently performed self-care behaviors were concerned with symptom monitoring or management. There were no significant relationships between the total self-care behavior score and any of the BCFs; however, a number of significant relationships between BCFs and individual self-care behaviors were observed. There was a significant relationship between the mean total knowledge score and the total mean self-care score (r = 0.21, P =.026). Detailed information about the influence of BCFs on the performance of specific HF self-care behaviors can help nurses tailor interventions to the patient's situation.

    ABSTRACT: To describe the fatigue experience of patients with cancer receiving radiation therapy and determine to what extent diverse correlates of fatigue affect fatigue onset, duration, and distress. Descriptive correlational study completed by secondary data analysis. Data were obtained from 384 subjects recruited from two urban, university-affiliated, radiation oncology clinics located in a large, Midwestern city. The effects of health indicators and treatment site on fatigue onset, duration, and distress were examined using correlational analyses and analyses of variance. Hemoglobin, health status, global symptom distress, mood disturbance, treatment site, and fatigue onset, duration, and distress. Fatigue started near the middle of the second week of treatment, was moderately distressing, and lasted approximately 32 days. Higher levels of health and hemoglobin at the start of therapy were associated with a delayed onset, shorter duration, and lower levels of fatigue distress. In contrast, higher pretreatment levels of global symptom distress and mood disturbance were associated with an earlier onset, longer duration, and greater severity of fatigue distress. The fatigue experience in patients undergoing radiation therapy is highly individualized. Variations in the health states of patients as well as the area of the body being treated can influence fatigue onset, duration, and distress. Pretreatment screening for fatigue and its correlates is needed to identify patients at risk for an earlier onset, longer duration, and more distressing levels of fatigue.
