Symptom clusters in breast cancer across 3 phases of the disease.

The purpose of this exploratory, secondary analysis was to compare the prevalence of symptoms attributable to breast cancer or its treatment and to identify and describe symptom clusters across 3 phases of the disease. A pooled analysis was conducted by combining existing symptom data collected at the baseline assessment from 3 independent studies of women with breast cancer. Study I had 40 women with early-stage breast cancer following primary surgery for their disease and prior to the initiation of adjuvant therapy. Study II had 88 women with stage I, II, or III breast cancer who had completed surgery and adjuvant chemotherapy and may have been receiving hormonal therapy. Study III had 26 women with metastatic breast cancer (stage IV). Three symptom clusters were identified corresponding to 3 different phases of the breast cancer experience. Each cluster was composed of symptoms related to fatigue, perceived cognitive impairment, and mood problems. Future studies are needed to prospectively examine whether these symptoms cluster across 3 phases of breast cancer and the effect of these clusters on the functional ability and quality of life in women with breast cancer.

Memory impairments with adjuvant anastrozole versus tamoxifen in women with early-stage breast cancer

Objective: Hormones have been implicated as modulators of cognitive functioning. For instance, results of our previous work in women with breast cancer showed that cognitive impairment was more severe and involved more memory domains in those who received adjuvant tamoxifen therapy compared with women who received chemotherapy alone or no adjuvant therapy. Recently aromatase inhibitors such as anastrozole have been used in lieu of tamoxifen for the adjuvant treatment of postmenopausal women with hormone receptor-positive, early-stage breast cancer. Plasma estrogen levels are significantly lower in women who receive anastrozole compared with those who receive tamoxifen. We hypothesized, therefore, that anastrozole would have a more profound effect on cognitive function than tamoxifen, a mixed estrogen agonist/antagonist. Design: To test this hypothesis we compared cognitive function in women with early-stage breast cancer who received tamoxifen with those who received anastrozole therapy in a cross-sectional study. We evaluated cognitive function, depression, anxiety, and fatigue in 31 postmenopausal women with early-stage breast cancer who were between the ages of 21 and 65 years and treated with tamoxifen or anastrozole for a minimum of 3 months. Results: The results showed that women who received anastrozole had poorer verbal and visual learning and memory than women who received tamoxifen. Conclusions: Additional, prospective studies are needed to validate and confirm the changes in cognitive function associated with hormone therapy for breast cancer.

Symptom clusters in adults with chronic health problems and cancer as a comorbidity.

PURPOSE/OBJECTIVES To identify and compare symptom clusters in individuals with chronic health problems with cancer as a comorbidity versus individuals with chronic health problems who do not have cancer as a comorbidity and to explore the effect of symptoms on their quality of life. DESIGN Secondary analysis of data from two studies. Study 1 was an investigation of the efficacy of an intervention to improve medication adherence in patients with rheumatoid arthritis (RA). Study 2 was an investigation of the efficacy of an intervention for urinary incontinence (UI) in older adults. SETTING School of Nursing at the University of Pittsburgh. SAMPLE The sample for study 1 was comprised of 639 adults with RA. The sample for study 2 was comprised of 407 adults with UI. A total of 154 (15%) subjects had a history of cancer, 56 (9%) of the subjects with RA and 98 (25%) of the subjects with UI. METHODS Analysis of existing comorbidity and symptom data collected from both studies. MAIN RESEARCH VARIABLES Symptom clusters, chronic disease, and cancer as a comorbidity. FINDINGS Individuals with chronic health problems who have cancer may not have unique symptom clusters compared to individuals with chronic health problems who do not have cancer. CONCLUSIONS The symptom clusters experienced by the study participants may be more related to their primary chronic health problems and comorbidities. IMPLICATIONS FOR NURSING Additional studies are needed to examine symptom clusters in cancer survivors. As individuals are living longer with the disease, a comprehensive understanding of the symptom clusters that may be unique to cancer survivors with comorbidities is critical.

Effect of Reiki Therapy on Pain and Anxiety in Adults: An In-Depth Literature Review of Randomized Trials with Effect Size Calculations

The objective of this study was to calculate the effect of Reiki therapy for pain and anxiety in randomized clinical trials. A systematic search of PubMed, ProQuest, Cochrane, PsychInfo, CINAHL, Web of Science, Global Health, and Medline databases was conducted using the search terms pain, anxiety, and Reiki. The Center for Reiki Research also was examined for articles. Studies that used randomization and a control or usual care group, used Reiki therapy in one arm of the study, were published in 2000 or later in peer-reviewed journals in English, and measured pain or anxiety were included. After removing duplicates, 49 articles were examined and 12 articles received full review. Seven studies met the inclusion criteria: four articles studied cancer patients, one examined post-surgical patients, and two analyzed community dwelling older adults. Effect sizes were calculated for all studies using Cohens d statistic. Effect sizes for within group differences ranged from d = 0.24 for decrease in anxiety in women undergoing breast biopsy to d = 2.08 for decreased pain in community dwelling adults. The between group differences ranged from d = 0.32 for decrease of pain in a Reiki versus rest intervention for cancer patients to d = 4.5 for decrease in pain in community dwelling adults. Although the number of studies is limited, based on the size Cohens d statistics calculated in this review, there is evidence to suggest that Reiki therapy may be effective for pain and anxiety. Continued research using Reiki therapy with larger sample sizes, consistently randomized groups, and standardized treatment protocols is recommended.

Therapeutic use of selected herbs.

An increasing number of people in the United States are using herbs for health promotion and specific symptom management. Herbs are used to initiate healing through synergistic responses unlike the specific properties of pharmaceuticals. Anecdotal data comprise much of the popular information available about herbs. Scientific studies of the efficacy and safety of herbs, although on the rise, are less available than other drug trials. Clinicians need an appropriate knowledge base for dealing with patients who take herbal preparations as well as the ability to confidently include herbal preparations in their formulary. In this article, five common herbs are reviewed. The effects, clinical studies, side effects, and dosing regimens for aloe vera, arnica, black cohosh, evening primrose oil, and saw palmetto are described.

The Assessment and Non-Pharmacologic Treatment of Procedural Pain From Infancy to School Age Through a Developmental Lens: A Synthesis of Evidence With Recommendations.

UNLABELLED The 2011 IOM report stated that pain management in children is often lacking especially during routine medical procedures. The purpose of this review is to bring a developmental lens to the challenges in assessment and non-pharmacologic treatment of pain in young children. METHOD A synthesis of the findings from an electronic search of PubMed and the university library using the keywords pain, assessment, treatment, alternative, complementary, integrative, infant, toddler, preschool, young, pediatric, and child was completed. A targeted search identified additional sources for best evidence. RESULTS Assessment of developmental cues is essential. For example, crying, facial expression, and body posture are behaviors in infancy that indicate pain: however in toddlers these same behaviors are not necessarily indicative of pain. Preschoolers need observation scales in combination with self-report while for older children self-report is the gold standard. Pain management in infants includes swaddling and sucking. However for toddlers, preschoolers and older children, increasingly sophisticated distraction techniques such as easily implemented non-pharmacologic pain management strategies include reading stories, watching cartoons, or listening to music. DISCUSSION A developmental approach to assessing and treating pain is critical. Swaddling, picture books, or blowing bubbles are easy and effective when used at the appropriate developmental stage and relieve both physical and emotional pain. Untreated pain in infants and young children may lead to increased pain perception and chronic pain in adolescents and adults. Continued research in the non-pharmacological treatment of pain is an important part of the national agenda.

A Randomized Clinical Trial of Auricular Point Acupressure for Chronic Low Back Pain: A Feasibility Study

Objectives. This prospective, randomized clinical trial (RCT) was designed to investigate the feasibility and effects of a 4-week auricular point acupressure (APA) for chronic low back pain (CLBP). Methods. Participants were randomized to either true APA (true acupoints with taped seeds on the designated ear points for CLBP) or sham APA (sham acupoints with taped seeds but on different locations than those designated for CLBP). The duration of treatment was four weeks. Participants were assessed before treatment, weekly during treatment, and 1 month following treatment. Results. Participants in the true APA group who completed the 4-week APA treatment had a 70% reduction in worst pain intensity, a 75% reduction in overall pain intensity, and a 42% improvement in disability due to back pain from baseline assessment. The reductions of worst pain and overall pain intensity in the true APA group were statistically greater than participants in the sham group (P < 0.01) at the completion of a 4-week APA and 1 month followup. Discussion. The preliminary findings of this feasibility study showed a reduction in pain intensity and improvement in physical function suggesting that APA may be a promising treatment for patients with CLBP.

Nursing perspective of boyer’s scholarship paradigm

With nursings entrance into the mainstream of academic life, nursing faculty are being held to the same standards of scholarship that apply to other disciplines. Boyers paradigm of scholarship expands the traditional emphasis placed on research to include the scholarship of application, integration, and teaching. A statement of scholarship that applies Boyers paradigm to nursing was prepared by nursing faculty and is presented with examples of statement-guided activities, such as program planning, faculty promotion decisions, and mentorship of faculty.

The Menopause-Specific Quality of Life Questionnaire: psychometric evaluation among breast cancer survivors.

Objective:The aim of this study was to evaluate the psychometric properties of the Menopause-Specific Quality of Life Questionnaire (MENQOL) in a sample of breast cancer survivors experiencing menopausal symptoms. Methods:This was a secondary analysis of MENQOL psychometric data from two larger parent studies investigating acupuncture for the relief of menopausal symptoms among breast cancer survivors. Reliability was assessed for each subscale of the MENQOL via (1) internal consistency reliability with Cronbach &agr; and (2) test-retest reliability at multiple follow-up points with intraclass correlation coefficients and r. Convergent and discriminant validities were assessed via correlations of the vasomotor and psychosocial MENQOL subscales with select items in the Kupperman index and daily symptom diary. A principal components analysis was performed to determine construct validity. Results:For each subscale, Cronbach &agr; was 0.70 or greater. All subscale test-retest reliabilities at first follow-up were significant and at least moderately correlated (≥0.450; rs and intraclass correlation coefficients). Convergent validity was moderate between the vasomotor and psychosocial subscales and the symptom diary (r ≥ 0.410, P < 0.001) and larger between these domains and the Kupperman index (r ≥ 0.614, P < 0.001). In the same subscales, discriminant validity was supported by low, nonsignificant correlations (r ≤ 0.176, P > 0.05). The principal components analysis revealed a latent structure nearly identical to the prespecified instrument domains, with the exception of the physical domain. Conclusions:With results comparable with those obtained in previous psychometric work, the MENQOL seems to be a reliable and valid instrument to assess quality of life in postmenopausal breast cancer survivors.

Weighing worth against uncertain work: the interplay of exhaustion, ambiguity, hope and disappointment in mothers breastfeeding late preterm infants

Poor breastfeeding outcomes among late preterm infants (LPIs) have been attributed to inadequate breast milk transfer stemming from physiological immaturities. However, breastfeeding is more than a biological phenomenon, and it is unclear how mothers of LPIs manage other factors that may also impact the breastfeeding course. Using grounded theory methods and incorporating serial post-partum interviews with several novel data collection techniques, we examined breastfeeding establishment over a 6-8-week-period among 10 late preterm mother-infant dyads recruited from a maternity hospital in Pittsburgh, Pennsylvania, USA. We found that breastfeeding in the LPI population was a fluctuating, cascade-like progression of trial and error, influenced by a host of contextual factors and events and culminating with breastfeeding continuation (with or without future caveats for duration or exclusivity of breastfeeding) or cessation. The trajectory was explained by the basic psychosocial process Weighing Worth against Uncertain Work, which encompassed the tension among breastfeeding motivation, the intensity of breastfeeding work and the ambiguity surrounding infant behaviour and feeding cues. Several sub-processes were also identified: Playing the Game, Letting Him Be the Judge vs. Accommodating Both of Us and Questioning Worth vs. Holding out Hope. If valid, our theoretical model indicates a need for earlier, more extensive and more qualified breastfeeding support for mothers of LPIs that emphasizes the connection between prematurity and observed feeding behaviours.
