Abstract
Introduction: Breast cancer patients and survivors frequently report fatigue, emotional, and cognitive disturbances, which reduce performance at all levels of occupation and make life quality issues a considerable clinical concern. The aim of this study is to evaluate attention and emotion regulation across radiotherapy period and the possible effects of complementary alternative medicine (CAM). Methods: Fifty-seven patients with unilateral breast cancer underwent surgery and systemic chemotherapy before participating in this double-blind randomized study. Two thirds were given CAM (n = 38) while the rest received placebo (carrier only, n = 19). Patients’ attention and anxiety were physiologically tested at baseline, 2 and 4 weeks during the radiation period as well as 1-month after the end of radiation session. Results: Both groups showed similar levels of anxiety with no significant differences at baseline nor post-radiotherapy. Long-term significant recovery of attention performance was observed in the CAM patients, accompanied by a similar tendency in anxiety level, measured by the eye-blink probability. Conclusions: This study physiologically validates the attention impairment reported among breast cancer survivors; also, it depicted a beneficial late-effect of a routine CAM on attention dysregulation. The suggested non-invasive physiological measures can physiologically monitor patients’ psychological and cognitive well-being as well as evaluate the beneficial effect of CAM in breast cancer patients by assessing their coping ability to support the treatment plan. Thus, the results have potential clinical implications on patients’ and survivors’ quality of life. Trial Registration: NIH, NCT02890316. Registered July 2016, http://www.ClinicalTrials.gov

Resatorvid Relieves Breast Cancer Complicated with Depression by Inactivating Hippocampal Microglia Through TLR4/NF-κB/NLRP3 Signaling Pathway. Cancer Manag Res 2020; 12:13003-13014. [PMID: 33376394 PMCID: PMC7755376 DOI: 10.2147/cmar.s279800] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Accepted: 11/21/2020] [Indexed: 12/28/2022] Open
Abstract
Background Breast cancer is one of the most common cancer with high risk in females all over the world. It is usually complicated with depression, which can further accelerate the development and progression of breast tumors. We aim to identify a new drug and identify its functional mechanism in the regulation of hippocampal microglia (MG) in breast cancer complicated with depression (BCCD). Methods The activation model of MG was established by treatments from corticosterone (CORT) or lipopolysaccharides (LPS). The inhibitory effects of resatorvid on MG were investigated by CCK-8, ROS, immunofluorescence, TUNEL, scratch test, ELISA, RT-qPCR and Western blot. BCCD animal model was established using 4T1 inflammatory breast cancer cells and CORT treatment in vitro. Open field experiment (OFE), tail suspension test (TST), ELISA, RT-qPCR and Western blot experiments were utilized to examine the effects of resatorvid on the animal model in vivo. Results The cell viability and migration ability of the BCCD model group were suppressed. The expressions of inflammatory factors, ROS, and the apoptotic rate of the BCCD model group were up-regulated, in contrast to the control group. The expressions related to the TLR4/NF-κB/NLRP3 signaling in the BCCD model group were also elevated. Resatorvid reversed the above changes, which showed good therapeutic effects in depression-related behavioral changes, tumor treatment, and blood–brain barrier function. Conclusion In summary, resatorvid inhibited the activation of hippocampal MG in BCCD by regulating TLR4/NF-κB/NLRP3 signaling pathway.

Assessment of Fatigue Using Wearable Sensors: A Pilot Study. Digit Biomark 2020; 4:59-72. [PMID: 33442581 DOI: 10.1159/000512166] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Accepted: 10/06/2020] [Indexed: 12/30/2022] Open
Abstract
Background Fatigue is a broad, multifactorial concept encompassing feelings of reduced physical and mental energy levels. Fatigue strongly impacts patient health-related quality of life across a huge range of conditions, yet, to date, tools available to understand fatigue are severely limited. Methods After using a recurrent neural network-based algorithm to impute missing time series data form a multisensor wearable device, we compared supervised and unsupervised machine learning approaches to gain insights on the relationship between self-reported non-pathological fatigue and multimodal sensor data. Results A total of 27 healthy subjects and 405 recording days were analyzed. Recorded data included continuous multimodal wearable sensor time series on physical activity, vital signs, and other physiological parameters, and daily questionnaires on fatigue. The best results were obtained when using the causal convolutional neural network model for unsupervised representation learning of multivariate sensor data, and random forest as a classifier trained on subject-reported physical fatigue labels (weighted precision of 0.70 ± 0.03 and recall of 0.73 ± 0.03). When using manually engineered features on sensor data to train our random forest (weighted precision of 0.70 ± 0.05 and recall of 0.72 ± 0.01), both physical activity (energy expenditure, activity counts, and steps) and vital signs (heart rate, heart rate variability, and respiratory rate) were important parameters to measure. Furthermore, vital signs contributed the most as top features for predicting mental fatigue compared to physical ones. These results support the idea that fatigue is a highly multimodal concept. Analysis of clusters from sensor data highlighted a digital phenotype indicating the presence of fatigue (95% of observations) characterized by a high intensity of physical activity. Mental fatigue followed similar trends but was less predictable. Potential future directions could focus on anomaly detection assuming longer individual monitoring periods. Conclusion Taken together, these results are the first demonstration that multimodal digital data can be used to inform, quantify, and augment subjectively captured non-pathological fatigue measures.

Mild to Moderate Cognitive Impairment Does Not Affect the Ability to Self-Report Important Symptoms in Patients With Cancer: A Prospective Longitudinal Multinational Study (EPCCS). J Pain Symptom Manage 2020; 60:346-354.e2. [PMID: 32179133 DOI: 10.1016/j.jpainsymman.2020.03.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Revised: 03/04/2020] [Accepted: 03/06/2020] [Indexed: 11/29/2022]
Abstract
CONTEXT Patients with advanced cancer commonly suffer from both distressing symptoms and cognitive impairment, but the effect of cognitive impairment on the reliability and validity of symptom self-report is unknown. OBJECTIVES To evaluate the reliability and validity of symptom self-report in cancer outpatients with and without mild to moderate cognitive impairment. METHODS This was an analysis of the longitudinal European Palliative Care Cancer Symptom study of adults with incurable cancer in specialized palliative care (30 centers across 12 countries). Patients who could not comply with the study because of severe cognitive impairment were excluded. Cognitive status on the Mini-Mental State Examination short version and nine symptoms (pain, tiredness, drowsiness, nausea, appetite, breathlessness, depression, anxiety, and well-being) using the revised Edmonton Symptom Assessment System were self-reported at baseline and one-month follow-up. Reliability was analyzed using intraclass correlation coefficients and validity using regression of each symptom with health-related quality of life (HrQoL) measured with European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 for Palliative Care. RESULTS A total of 1047 patients were included: mean age of 62.9 years; 54.4% women; main cancer types were of digestive organs (26.6%), breast (21.6%), and lungs (21.2%). Cognitive impairment was present in 181 (17.3%) at baseline and associated with worse self-reported tiredness, drowsiness, appetite, and depression. Reliability (intraclass correlation coefficient) and validity (associations with HrQoL) were similar between people with/without cognitive impairment across the nine symptoms, except breathlessness, which showed a weaker relation to HrQoL in patients with cognitive impairment. Findings were robust in sensitivity analyses and after controlling for potential confounders. CONCLUSION In advanced cancer, self-report of nine major symptoms was reliable and valid also in people with mild-to-moderate cognitive impairment.

Work-specific cognitive symptoms and the role of work characteristics, fatigue, and depressive symptoms in cancer patients during 18 months post return to work. Psychooncology 2018; 27:2229-2236. [PMID: 29920845 DOI: 10.1002/pon.4800] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Revised: 06/05/2018] [Accepted: 06/05/2018] [Indexed: 11/10/2022]
Abstract
OBJECTIVE Cancer patients can experience work-specific cognitive symptoms post return to work. The study aims to (1) describe the course of work-specific cognitive symptoms in the first 18 months post return to work and (2) examine the associations of work characteristics, fatigue and depressive symptoms with work-specific cognitive symptoms over time. METHODS This study used data from the 18-month longitudinal "Work Life after Cancer" cohort. The Cognitive Symptom Checklist-Work Dutch Version (CSC-W DV) was used to measure work-specific cognitive symptoms. Linear mixed models were performed to examine the course of work-specific cognitive symptoms during 18-month follow-up; linear regression analyses with generalized estimating equations were used to examine associations over time. RESULTS Working cancer patients examined with different cancer types were included (n = 378). Work-specific cognitive symptoms were stable over 18 months. At baseline, cancer patients reported more working memory symptoms (M = 32.0; CI, 30.0-34.0) compared with executive function symptoms (M = 19.3; CI, 17.6-20.9). Cancer patients holding a job with both manual and nonmanual tasks reported less work-specific cognitive symptoms (unstandardized regression coefficient b = -4.80; CI, -7.76 to -1.83) over time, compared with cancer patients with a nonmanual job. Over time, higher depressive symptoms were related to experiencing more overall work-specific cognitive symptoms (b = 1.27; CI, 1.00-1.55) and a higher fatigue score was related to more working memory symptoms (b = 0.13; CI, 0.04-0.23). CONCLUSIONS Job type should be considered when looking at work-specific cognitive symptoms over time in working cancer patients. To reduce work-specific cognitive symptoms, interventions targeted at fatigue and depressive symptoms might be promising.

Abstract
BACKGROUND AND AIMS Dysphagia can be associated with significant morbidity in cancer patients. We aimed to develop and evaluate dysphagia screener tools for use in observational studies (phase 1) and for routine symptom monitoring in clinical care (phase 2). METHODS Various dysphagia or odynophagia screening questions, selected after an expert panel reviewed the content, criterion, and construct validity, were compared with either functional assessment of cancer therapy - esophageal cancer (FACT-E) Swallowing Index Cut-Off Values or to questions adapted from the Patient Reported Outcomes for Common Terminology Criteria for Adverse Events. Sensitivity, specificity, and patient acceptability were assessed. RESULTS In Phase 1 (n = 178 esophageal cancer patients), the screening question "How are you currently eating?" had the highest sensitivities and specificities against various Swallowing Index Cut-Off Value cut-offs, with the best optimal cutoff associated with weight loss (80% sensitivity and 75% specificity). In phase 2 (255 head and neck, gastro-esophageal, and thoracic cancer patients), a single question screener ("Do you experience any difficulty or pain upon swallowing?") versus a Patient Reported Outcomes for Common Terminology Criteria for Adverse Events-like gold standard generated sensitivities between 86% and 94% and specificities between 93% and 100%. This screening question (+/- follow-up questions) had a median completion time of under 2 minutes, and >90% of patients were willing to complete the survey electronically, did not feel that survey made clinic visit more difficult, and did not find the questions upsetting or distressful. CONCLUSION Our results demonstrate that these screener tools ("How are you currently eating?", "Do you experience any difficulty or pain upon swallowing?") can effectively screen dysphagia symptoms without increasing cancer outpatient clinic burden, both in observational studies and for routine clinical monitoring.

Abstract
BACKGROUND Much has been done to examine the psychological impact of cancer treatment, but it remains unclear to what extent anxiety and depression is related to symptom prevalence. The present study concerned the characteristics and frequency of distress as related to symptom prevalence in cancer patients undergoing chemotherapy in Malaysia. MATERIALS AND METHODS Participants were 303 consecutive adult cancer patients undergoing chemotherapy in an academic medical center. The short form Memorial Symptom Assessment Scale (MSAS-SF), which covers three domains of symptoms (global distress, physical- and psychological symptoms) was used to cross-sectionally measure symptom frequency and associated distress via self-reporting. One-way ANOVA and t-tests were used to test mean differences among MSAS-SF subscale scores. RESULTS Complete data were available for 303 patients. The mean number of symptoms was 14.5. The five most prevalent were fatigue, dry mouth, hair loss, drowsiness and lack of appetite. Overall, symptom burden and frequency were higher than in other published MSAS-SF studies. Higher symptom frequency was also found to be significantly related to greater distress in cancer patients undergoing chemotherapy. CONCLUSIONS Patients undergoing chemotherapy suffer from multiple physical and psychological symptoms. Better symptom control or palliative care is needed. Greater frequency of reported symptoms may also indicate a subconscious bid by patients for care and reassurance - thus tailored intervention to manage distress should be offered.

Abstract
OPINION STATEMENT Neurocognitive deficits are common with brain tumors. If assessed at presentation using detailed neurocognitive tests, problems are detected in 80 % of cases. Neurocognition may be affected by the tumor, its treatment, associated medication, mood, fatigue, and insomnia. Interpretation of neurocognitive problems should be considered in the context of these factors. Early post-operative neurocognitive rehabilitation for brain tumor patients will produce rehabilitation outcomes (e.g., quality of life, improved physical function, subjective neurocognition) equivalent to stroke, multiple sclerosis, and head injury, but the effect size and duration of benefit needs further research. In stable patients treated with radiotherapy +/- chemotherapy, the most frequent causes of distress include neurocognitive problems, psychological factors of anxiety, depression, fatigue, and sleep. Exercise, neurocognitive training, neurocognitive behavioral therapy, and medications to treat fatigue, behavior, memory, mood, and removal of drugs that may be associated with neurocognitive side effects (e.g., anti-epileptic drugs) all show promise in helping patients to manage the effects of their neurocognitive impairments better. As these are complex symptoms, multidisciplinary expertise is necessary to evaluate the influence of each variable to plan appropriate support and intervention. Neurocognitive rehabilitation should therefore occur in parallel with disease-centered, medical management from the outset. It should not occur in series, as a restricted phase in a patient's pathway. It should be considered in the pre- and post-operative period where there are good prospects of recovery, as one would for any brain-injured patient, so that the person may reach their optimal physical, sensory, intellectual, psychological, and social functional level. Yet the identification and selection of patients for early neurological rehabilitation and routine evaluation of cognition is uncommon in neurosurgical wards.

Abstract
OBJECTIVE The Toronto Hospital Alertness Test (THAT) scale was designed to measure alertness, defined as the capacity of the mind to respond appropriately to external and internal stimuli. The present study's aim is to determine normative values of alertness on the THAT and to explore the relationship among excessive daytime sleepiness, fatigue, depressive symptoms, and alertness. METHODS Normative data were collected from 60 healthy males and females. To explore the relationship among alertness, daytime sleepiness, fatigue, depression, and anxiety, data were collected from charts of sleep clinic patients. All study subjects completed measures for fatigue, sleepiness, depressive symptoms, and anxiety. RESULTS The average score on the THAT was 34.9±7.2 (range 22-50) for the control group. The cutoff score for the THAT, indicative of clinically significant reduced alertness, was determined to be ≤20.5 (mean -2 SD). THAT alertness scores were found to be modestly, significantly, and negatively correlated with fatigue levels (r=-0.39, P<0.001), depressive symptoms (r=-0.53, P<0.001), and anxiety symptoms (r=-0.41, P<0.001). No correlations were found between alertness levels and daytime sleepiness. Regression analyses revealed a significant model (F=19.9, P<0.001, adjusted R (2)=0.35) with depressive symptoms (P<0.001) and fatigue (P=0.006) emerging as the only significant predictors of scores on the THAT. CONCLUSION The findings of this study support that sleepiness is not the same as poor alertness. Depressive symptoms and fatigue, but not sleepiness, were found to have a strong and significant impact on levels of alertness. This is the first study to link poor alertness to depressive symptoms.

Abstract
Purpose The study objectives are to translate the 21-item Cognitive Symptom Checklist-Work (CSC-W21) to Dutch (CSC-W DV) and to validate the CSC-W DV in working cancer patients. Methods The CSC-W21 was cross-culturally translated and adapted to a Dutch version. In this 19-item version, the dichotomous response option was changed to an ordinal five-point scale. A validation study of the CSC-W DV was conducted among cancer patients who had returned to work during or following cancer treatment. Internal consistency (Cronbach’s α), structural validity (exploratory factor analysis) and construct validity (hypothesis testing) were evaluated. Results In a cohort of 364 cancer patients, 341 (94 %) completed the CSC-W DV (aged 50.6 ± 8.6 years, 60 % women). Exploratory factor analysis revealed two subscales ‘working memory’ and ‘executive function’. The internal consistency of the total scale and subscales was high (Cronbach’s α = 0.93–0.95). Hypothesis testing showed that self-reported cognitive limitations at work were related to work functioning (P < 0.001), fatigue (P = 0.001) and depressive symptoms (P < 0.001), but not to self-rated health (P = 0.14). Conclusions The CSC-W DV showed high internal consistency and reasonable construct validity for measuring work-specific cognitive symptoms in cancer patients. The CSC-W DV was associated in expected ways with work functioning, fatigue and depressive symptoms. Implications for Cancer Survivors It is important to enhance knowledge about cognitive symptoms at work in cancer patients, to guide and support cancer patients as good as possible when they are back at work and to improve their work functioning over time.

Abstract
Although the impact of cancer and associated treatments on cognitive functioning is becoming an increasingly recognized problem, there are few published studies that have investigated psychological interventions to address this issue. A waitlist randomized controlled trial methodology was used to assess the efficacy of a group cognitive rehabilitation intervention ("ReCog") that successfully targeted cancer-related cognitive decline in previously published pilot research. Participants were 29 cancer survivors who were randomly allocated to either the intervention group or a waitlist group who received the intervention at a later date, and 16 demographically matched community volunteers with no history of cancer (trial registration ACTRN12615000009516, available at http://www.ANZCTR.org.au/ACTRN12615000009516.aspx). The study was the first to include an adapted version of the Traumatic Brain Injury Self-Efficacy Scale to assess cognitive self-efficacy (CSE) in people who have experienced cancer. Results revealed participating in the intervention was associated with significantly faster performance on one objective cognitive task that measures processing speed and visual scanning. Significantly larger improvements for the intervention group were also found on measures of perceived cognitive impairments and CSE. There was some evidence to support the roles of CSE and illness perceptions as potential mechanisms of change for the intervention. Overall, the study provided additional evidence of feasibility and efficacy of group psychological intervention for targeting cancer-related cognitive decline.

Abstract
Symptom clusters are gaining importance given HIV/AIDS patients experience multiple, concurrent symptoms. This study aimed to: determine clusters of patients with similar symptom combinations; describe symptom combinations distinguishing the clusters; and evaluate the clusters regarding patient socio-demographic, disease and treatment characteristics, quality of life (QOL) and functional performance. This was a cross-sectional study of 302 adult HIV/AIDS outpatients consecutively recruited at two teaching and referral hospitals in Uganda. Socio-demographic and seven-day period symptom prevalence and distress data were self-reported using the Memorial Symptom Assessment Schedule. QOL was assessed using the Medical Outcome Scale and functional performance using the Karnofsky Performance Scale. Symptom clusters were established using hierarchical cluster analysis with squared Euclidean distances using Ward's clustering methods based on symptom occurrence. Analysis of variance compared clusters on mean QOL and functional performance scores. Patient subgroups were categorised based on symptom occurrence rates. Five symptom occurrence clusters were identified: Cluster 1 (n=107), high-low for sensory discomfort and eating difficulties symptoms; Cluster 2 (n=47), high-low for psycho-gastrointestinal symptoms; Cluster 3 (n=71), high for pain and sensory disturbance symptoms; Cluster 4 (n=35), all high for general HIV/AIDS symptoms; and Cluster 5 (n=48), all low for mood-cognitive symptoms. The all high occurrence cluster was associated with worst functional status, poorest QOL scores and highest symptom-associated distress. Use of antiretroviral therapy was associated with all high symptom occurrence rate (Fisher's exact=4, P<0.001). CD4 count group below 200 was associated with the all high occurrence rate symptom cluster (Fisher's exact=41, P<0.001). Symptom clusters have a differential, affect HIV/AIDS patients' self-reported outcomes, with the subgroup experiencing high-symptom occurrence rates having a higher risk of poorer outcomes. Identification of symptom clusters could provide insights into commonly co-occurring symptoms that should be jointly targeted for management in patients with multiple complaints.

Abstract
PURPOSE/OBJECTIVES To comprehensively assess the patient and illness or treatment factors that may predict nonadherence to adjuvant endocrine therapy and to explore whether an interaction occurs between these factors in women with breast cancer. DESIGN Repeated-measures design. SETTING The Outpatient Services of the Women's Cancer Program at the University of Pittsburgh Cancer Institute and participants' homes. SAMPLE 91 women with early-stage breast cancer who received endocrine therapy. METHODS Adherence was assessed continuously for the first 18 months of endocrine therapy. Patient and illness or treatment factors were assessed at four time points (Time 1 to Time 4). Time 1 (baseline) was within two weeks prior to the initiation of endocrine therapy. Times 2-4 occurred at six-month intervals, as many as 18 months after Time 1. MAIN RESEARCH VARIABLES Adherence, patient factors, and illness or treatment factors. FINDINGS Adherence to endocrine therapy declined significantly during the first 18 months of treatment in women with breast cancer. The presence of negative mood and symptoms before starting treatment predicted nonadherence to endocrine therapy over time. Perceptions of financial hardship, symptoms, disease stage, and more complex medication regimens intensified the effect of negative mood on adherence over time. CONCLUSIONS Women with breast cancer may be at risk for nonadherence to prescribed endocrine therapy if they experience depression or anxiety and symptoms prior to initiating therapy. IMPLICATIONS FOR NURSING Oncology nurses should be alert to women with breast cancer who are depressed or anxious or who are experiencing symptoms. Management of negative mood and symptoms may result in better adherence.

Abstract
BACKGROUND Interferon (IFN)-α therapy for chronic hepatitis C virus infection is frequently associated with depression. The routine prophylaxis with antidepressants might expose patients to adverse effects, hence, the need for alternative preventive interventions. Omega-3 polyunsaturated fatty acids are safe and effective essential nutritional compounds used for the treatment of depression, putatively through an anti-inflammatory action. In addition, lower erythrocyte levels of omega-3 polyunsaturated fatty acids have been associated with an increased risk of IFN-induced depression. METHODS We conducted a 2-week, double-blind, placebo-controlled trial comparing eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and placebo for the prevention of IFN-α-induced depression. A total of 162 patients consented to participate and were randomized to the study. All of the patients completed the 2-week trial; 152 participants were followed throughout the 24 weeks of IFN-α treatment and were included in the analysis. RESULTS Compared with placebo, the incident rates of IFN-α-induced depression were significantly lower in EPA-treated but not in DHA-treated patients (10% and 28%, respectively, versus 30% for placebo, p = .037). Both EPA and DHA significantly delayed the onset of IFN-induced depression (week of onset: 12.0 and 11.7, respectively, versus 5.3 for placebo, p = .002). EPA and DHA were both well tolerated in this population. EPA treatment increased both EPA and DHA erythrocyte levels, but DHA only increased DHA erythrocyte levels. CONCLUSIONS EPA is effective in the prevention of depression in hepatitis C virus patients received IFN-α therapy. Our study confirms the notion that anti-inflammatory strategies are effective antidepressants in the context of depression associated with inflammation.

PURPOSE/OBJECTIVES To comprehensively assess the patient and illness or treatment factors that may predict nonadherence to adjuvant endocrine therapy and to explore whether an interaction occurs between these factors in women with breast cancer. DESIGN Repeated-measures design. SETTING The Outpatient Services of the Women's Cancer Program at the University of Pittsburgh Cancer Institute and participants' homes. SAMPLE 91 women with early-stage breast cancer who received endocrine therapy. METHODS Adherence was assessed continuously for the first 18 months of endocrine therapy. Patient and illness or treatment factors were assessed at four time points (Time 1 to Time 4). Time 1 (baseline) was within two weeks prior to the initiation of endocrine therapy. Times 2-4 occurred at six-month intervals, as many as 18 months after Time 1. MAIN RESEARCH VARIABLES Adherence, patient factors, and illness or treatment factors. FINDINGS Adherence to endocrine therapy declined significantly during the first 18 months of treatment in women with breast cancer. The presence of negative mood and symptoms before starting treatment predicted nonadherence to endocrine therapy over time. Perceptions of financial hardship, symptoms, disease stage, and more complex medication regimens intensified the effect of negative mood on adherence over time. CONCLUSIONS Women with breast cancer may be at risk for nonadherence to prescribed endocrine therapy if they experience depression or anxiety and symptoms prior to initiating therapy. IMPLICATIONS FOR NURSING Oncology nurses should be alert to women with breast cancer who are depressed or anxious or who are experiencing symptoms. Management of negative mood and symptoms may result in better adherence.

Abstract
AIM The purpose of this study was to investigate symptom severity in advanced non-small cell lung cancer patients prior to gefitinib treatment and at 1-, 3- and 6-month intervals after starting treatment. METHODOLOGY Fifty seven patients completed the Taiwanese version of the M.D. Anderson Symptom Inventory. The data were analysed using descriptive statistics, the Friedman non-parametric test, and Pearson correlation coefficients. RESULTS Symptoms of nausea, difficulty remembering, lack of appetite, sadness, and vomiting increased at 1 month after treatment started, pain and shortness of breath increased at 3 months, and disturbed sleep, drowsiness, and numbness increased after 6 months. Fatigue and dry mouth increased at 3 months after treatment started and then decreased. Only distress decreased throughout the course of treatment. CONCLUSION The findings may lead to the development of better clinical guidelines and improved information for patients on when to expect the greatest impact from their symptoms during the course of treatment.

Abstract
PURPOSE/OBJECTIVES To examine perceived cognitive effectiveness and worry in individuals with suspected lung cancer before and after surgical resection and to determine any differences between individuals with and without a postoperative diagnosis of lung cancer. DESIGN A repeated measures longitudinal design. SETTING A comprehensive cancer center and a Veterans Administration medical center in the midwestern United States. SAMPLE 15 men and 8 women aged 37-82 years (X = 61.4, SD = 10.7) with suspected lung cancer. METHODS Descriptive statistics were used to characterize data. Paired t tests and nonparametric correlation analysis were used to determine relationships among the main study variables. MAIN RESEARCH VARIABLES Perceived effectiveness in cognitive function as well as general and cancer-specific worry. FINDINGS Patients diagnosed with lung cancer were significantly older. Patients self-reported lowered perceived effectiveness in daily activities that require directed attention both pre- and postoperatively. Patients with nonmalignant postoperative reports had higher general worry at each time point, which was significant following surgery. CONCLUSIONS A diagnosis of suspected lung cancer may contribute to compromised perceived effectiveness in cognitive function. Nonmalignant pathology following a diagnosis of suspected lung cancer may be associated with continued worry. IMPLICATIONS FOR NURSING Nursing assessment and interventions aimed at supporting effective cognitive function and modifying worry for patients with suspected lung cancer are essential to optimize adjustment. KNOWLEDGE TRANSLATION Suspected lung cancer imposes high demands on cognitive and emotional function. Oncology nurses are in key positions to support patients during and following the diagnostic workup for lung cancer. Younger patients with nonmalignant postoperative reports may need continued follow-up.

Abstract
Although cancer incidence rates are increasing, recent statistical studies suggest that cancer patients are showing higher cure rates as well as improved overall survival rates for most cancer locations. These advances are explained by improved strategies in early diagnoses as well as improved cancer therapies. Therefore, the number of long-term cancer survivors has also increased, but only few studies, especially within the last years, have focused on psychosocial issues of this subgroup. Some studies show that overall quality of life of long-term cancer survivors is quite high and comparable to that of the normal population. Nevertheless, a substantial percentage of former patients shows reduced quality of life and suffers from various sequelae of cancer and its treatment. This review focuses on the most common psychosocial issue of long-term survivors such as reduced psychological wellbeing, neuropsychological deficits and cancer-related fatigue syndrome. Finally, recommendations for problem-oriented interventions as well as improvement of psychosocial care of long-term survivors are given.

Abstract
Cancer-related fatigue (CRF) is one of the most common symptoms reported by patients and is defined as the feeling of extraordinary exhaustion associated with a high level of distress, disproportionate to the patients' activity, and is not relieved by sleep or rest. Prevalence rates range from 59 to nearly 100% depending on the clinical status of the cancer. Except for chemotherapy-induced anemia, the mechanisms responsible for CRF are not yet completely understood. Therefore, CRF may be influenced by multiple possible somatic and psychosocial factors. CRF has been shown as either a short-term side effect of adjuvant cancer therapy or a chronic long-term late effect. Compared with other symptoms, such as pain or nausea, CRF is more distressing and often long lasting, with a strong impact on daily living and quality of life. The concept of fatigue has been widely elaborated and operationalized in different dimensions within the last few decades and specific instruments assessing fatigue in cancer populations have been developed. To support patients and alleviate CRF symptoms various treatment strategies are discussed in this article, including information and counseling, enhancement of activities, exercise and sports therapy, psychosocial interventions as well as pharmacological treatment. In most Western countries, treatment of CRF has been identified as a priority for advancing cancer patient care. This article gives an overview of the concept of CRF, its pathogenesis, assessment and treatment strategies.

An examination of cancer-related fatigue through proposed diagnostic criteria in a sample of cancer patients in Taiwan. BMC Cancer 2011; 11:387.

Abstract
Background Fatigue among cancer patients has often been reported in the literature; however, great variations have been documented, ranging from 15% to 90%, probably due to the lack of a widely accepted definition and established diagnostic criteria for cancer-related fatigue. The objective of this study was to evaluate the proposed International Statistical Classification of Diseases and Related Health Problems (10th revision) (ICD-10) criteria in a sample of cancer patients from a medical center and a regional teaching hospital in northern Taiwan. More accurate prevalence estimates of CRF may result in improved diagnoses and management of one of the most common symptoms associated with cancer and its treatment. Methods Since self-reporting from patients is the most effective and efficient method to measure fatigue, the ICD-10 criteria for fatigue were used. The ICD-10 criteria questionnaire was translated into Chinese and was approved by experts. Patients were recruited from outpatient palliative and oncology clinics and from palliative and oncology inpatient units. Results Of the 265 cancer patients that were interviewed between 21 October 2008 and 28 October 2009, 228 (86%) reported having at least 2 weeks of fatigue in the past month, and further evaluation with the ICD-10 criteria showed that 132 (49.8%) had cancer-related fatigue. Internal consistency was very good, which was indicated by a Cronbach alpha of 0.843. Conclusion The prevalence of diagnosable CRF in the patients in this sample, of whom most were under palliative treatment, was 49.8%, which was probably somewhat lower than in some of the previous reports that have used less-strict criteria. In addition, among the various criteria of the proposed diagnostic criteria, the most frequently reported symptoms in our sample populations were regarding sleep disturbance and physical factors. Although they will require further replication in other samples, these formal diagnostic criteria can serve as a step toward a common language and a better understanding of the severity range of CRF.

Abstract
Background Studies have assessed gender differences on symptoms commonly experienced by cancer patients at various stages in their disease trajectory using heterogeneous cancer populations with different tumor types. The purpose of our study was to evaluate the effect of gender on symptoms among patients with bone metastases while controlling for gender-specific malignancies. Methods A retrospective review of patients receiving palliative radiotherapy for bone metastases was conducted on patients that completed the Brief Pain Inventory (BPI) or Edmonton Symptom Assessment System (ESAS) questionnaires from 1999 - 2004. Baseline and follow-up BPI and ESAS symptom scores were compared between males and females, with and without controlling for gender-specific tumors. Results A total of 900 patients completed baseline questionnaires: ESAS (n = 508) or BPI (n = 392). The most common tumor types were lung (26%), breast (25%) and prostate (24%). In all ESAS patients, females had significantly greater severity of tiredness, nausea, depression, anxiety and breathlessness. In the subgroup analysis when gender-specific primary cancers were removed (i.e., breast, prostate and gynecological), no significant differences in ESAS symptoms were found between genders. The BPI functional item of walking ability was significantly worse for females in both the overall and subgroup analyses. Females had worse symptoms at follow-up prior to the removal of gender-specific primaries in both ESAS and BPI. Conclusions Gender-specific cancers may significantly bias gender studies of cancer-related symptoms when primary tumor type is not taken into account. Gender differences are best assessed in gender-neutral primaries.

Abstract
Cancer is a disease characterized by dysregulation of multiple genes and is associated with symptoms such as cachexia, anorexia, fatigue, depression, neuropathic pain, anxiety, cognitive impairment, sleep disorders and delirium (acute confusion state) in medically ill patients. These symptoms are caused by either the cancer itself or the cancer treatment. During the past decade, increasing evidence has shown that the dysregulation of inflammatory pathways contributes to the expression of these symptoms. Cancer patients have been found to have higher levels of proinflammatory cytokines such as interleukin-6. The nuclear factor (NF)-κB is a major mediator of inflammatory pathways. Therefore, anti-inflammatory agents that can modulate the NF-κB activation and inflammatory pathways may have potential in improving cancer-related symptoms in patients. Because of their multitargeting properties, low cost, low toxicity and immediate availability, natural agents have gained considerable attention for prevention and treatment of cancer-related symptoms. How NF-κB and inflammatory pathways contribute to cancer-related symptoms is the focus of this review. We will also discuss how nutritional agents such as curcumin, genistein, resveratrol, epigallocatechin gallate and lycopene can modulate inflammatory pathways and thereby reduce cancer-related symptoms in patients.

Abstract
The aim of this study was to obtain a more in-depth understanding of cognitive impairments and concerns as described by patients with multiple myeloma and the strategies used to cope with them. Semi-structured qualitative interviews were undertaken with 15 multiple myeloma patients of differing age ranges and at various stages of their disease. Various cognitive impairments, such as problems with short-term memory, poor recall and lack of concentration were observed and/or expressed in at least 10 out of 15 patients, all of them long(er)-term survivors. In some patients cognitive impairments significantly interfered with their personal and professional lives, and for some patients these were described as permanent. The patients used various coping strategies, from denial, taking notes, writing diaries, reading simpler texts, using talking books and videos, to using systems for counting medication to cope with the results of their cognitive impairment. Our findings differ from much of the contemporary literature which states that if cognitive impairments in cancer patients occur, they are mostly mild and transient. More proactive supportive care is needed to help patients with multiple myeloma to cope with poorer cognitive functioning.

Abstract
It has been purported that inflammatory cytokines may be responsible for the aetiology of overtraining. The aim of the present study was to investigate the relationship between self-reported measures of overtraining and inflammatory cytokines. Eight elite male rowers were monitored in their natural training environment for 8 weeks prior to the 2007 Rowing World Championships. During this period of intense endurance training, self-report measures of overtraining and inflammatory cytokines (Interleukin (IL)-1beta, IL-6, IL-8, IL-10, IL-12p70, and Tumor Necrosis Factor (TNF)-alpha) were assessed fortnightly. Consistent with previous findings, proinflammatory cytokines IL-1beta and TNF-alpha were significantly associated (p <or= 0.05) with measures of depressed mood, sleep disturbances, and stress. Similarly, IL-6 was significantly associated (p <or= 0.01) with measures of depressed mood, sleep disturbances, and fatigue. These results are consistent with previous hypotheses describing how overtraining may be caused by excessive cytokine release, and lend further support for a cytokine hypothesis of overtraining.

Abstract
OBJECTIVE This study investigated performance-based and patient-reported cognitive limitations on work output. METHODS Working breast cancer survivors (BCS) (n = 122) and a non-cancer comparison group (NCCG; n = 113) completed measures of cognitive function, fatigue, distress, job stress, and work output. RESULTS Distress, fatigue, and job stress were higher in the BCS group who were on average 3-years post-treatment. Patient-reported cognitive limitations at work were related to work output in BCS (memory beta = 0.29; executive function beta = 0.26) only. Changes in work output were more responsive to changes in job stress and fatigue in the BCS group. CONCLUSIONS Reports of cognitive problems at work should be carefully followed up.

Abstract
Based on anecdotal reports and a few empirical studies, there is concern about the cognitive effects of cancer and its treatment effects among adults. A cross-sectional comparison of the cognitive performance of 541 elderly women who reported at least one hospitalization for cancer and 3,123 who had no reported hospitalizations for cancer was conducted. The difference between cancer survivors and those with no history of cancer on a screening test of global cognitive functioning was not significant, nor were there differences on a subtest of the global test that assesses verbal memory. Older women who report being hospitalized for cancer as adults may perform similar to women with no history of cancer on rudimentary cognitive tasks.

Abstract
INTRODUCTION The subjective experience of cancer survivorship can be assessed by various patient-reported outcome (PRO) methods, including measures of symptom burden and health-related quality of life (HRQOL). Symptom burden includes the presence and severity of multiple symptoms and the level of distress caused by symptoms that go untreated or unrelieved. The concept of symptom burden is more limited in scope than HRQOL but may provide information that better describes the status of various stages of survivorship. This paper contrasts symptom burden with general HRQOL and addresses the importance of including symptom burden as research tool throughout the trajectory of cancer survivorship. METHODS We summarized studies that illustrate both HRQOL and symptoms as outcomes of treatment and of descriptive studies of cancer survivorship. Survivorship was operationally defined as beginning at the completion of primary anticancer treatment. RESULTS HRQOL and symptom burden measures both provide meaningful but conceptually different data. Both types of measures are important in portraying aspects of cancer survivorship over time, although symptom burden may provide sufficient information to inform treatment decisions and identify long-term effects of cancer therapies. CONCLUSIONS Cancer survivors are at risk for multiple severe and persistent symptoms, and assessing and monitoring the severity and impact of these multiple symptoms is critical to understanding the survivorship experience. The inclusion of multiple symptom measures along with the development of new and better methods of long-term symptom tracking in survivors is a critical step in improving the heath status of survivors. IMPLICATIONS FOR CANCER SURVIVORS Late and long-term effects seen in cancer survivors have historically been understudied. Symptom burden is an important area of assessment that can be used to specifically describe the symptoms that distress survivors. More descriptive data in this growing population may help identify biological processes in symptom production and maintenance, and facilitate in the development of better treatment and prevention to enhance cancer survivorship.

Abstract
OBJECTIVE This study describes the experiences of fatigue and pain in incurable cancer patients and the treatment they receive. METHODS Patients were recruited via medical specialists from hospitals in the South and Southwest of the Netherlands. Hundred and twenty-five incurable cancer patients filled out a written questionnaire and were also interviewed at home. RESULTS Ninety percent reported to suffer from fatigue and 48% had pain. Forty-five percent had discussed fatigue with a healthcare professional and 55% had discussed pain. Fifteen percent reported to receive medical treatment for their fatigue and 29% received pain treatment. Treatment for fatigue and pain treatment had been recently adjusted in 4% of the patients with fatigue complaints and 21% of the patients with pain complaints. CONCLUSION Although fatigue is a more common problem than pain in patients with incurable cancer, less attention in the care is paid to fatigue and its treatment than to pain. PRACTICE IMPLICATIONS Fatigue deserves more attention in the care policy for incurable cancer patients and more research should be focused on interventions to address fatigue in this group of cancer patients.

Abstract
The purpose of this randomized, controlled clinical trial was to preliminarily examine the effects of a three-week walking exercise program (WEP) on fatigue-related experiences of acute myelogenous leukemia (AML) patients receiving chemotherapy. Eligible AML patients were randomly assigned to either an experimental group (n=11), which received 12 minutes of WEP per day, five days per week for three consecutive weeks, or to a control group (n=11), which received standard ward care. Effects of the WEP were assessed by seven indicators: worst and average fatigue intensities, fatigue interference with patients' daily life, 12-minute walking distance, overall symptom distress, anxiety, and depressive status. All patients were evaluated four times: before chemotherapy (baseline or Day 1), Day 7, Day 14, and Day 21 of chemotherapy. Data were analyzed by Generalized Estimating Equation and revealed that AML patients in the three-week WEP group had a significantly greater increase in 12-minute walking distance than the control group. Patients in the WEP also had lower levels of fatigue intensity and interference, symptom distress, anxiety, and depressive status than the control group. Although preliminary, our results strongly suggest that three weeks of systematic walking exercise is clinically feasible for AML patients undergoing chemotherapy and can effectively improve their fatigue-related experiences.

Abstract
The number one cause of cancer death in Taiwan is lung cancer. Of the few studies describing the experience of patients living with lung cancer, most use bivariate analyses to test associations between individual symptoms. Few have systematically investigated multiple symptoms. This prospective study was undertaken to explore the phenomenon of symptom distress, to investigate the presence of symptom clusters, and to examine the relationship of symptom clusters to symptom interference with daily life in Taiwanese lung cancer patients. A sample of 108 lung cancer patients was recruited using the Taiwanese version of the M. D. Anderson Symptom Inventory. Data were analyzed by hierarchical cluster analysis, factor analysis, Pearson correlation, t-test, and regression analysis. The top five most-severe symptoms were fatigue, sleep disturbance, lack of appetite, shortness of breath, and general distress. Factor analysis generated a two-factor solution (general and gastrointestinal symptoms) for symptom severity items. Consistent with the result from factor analysis, cluster analysis also indicated the same two cluster groups (general and gastrointestinal symptoms). Both clusters were significantly correlated with symptom interference items; however, the general symptom cluster presented higher correlation coefficients than did the gastrointestinal symptom cluster. These results provide an important basis for developing novel strategies to manage multiple symptoms in lung cancer patients and thereby improve their well-being.

Abstract
Cancer and its treatment produce multiple symptoms that significantly distress patients and impair function. Symptoms caused by treatment may delay treatment or lead to premature treatment termination, and residual treatment-related symptoms often complicate posttreatment rehabilitation. When treatment is no longer possible, symptom control becomes the focus of cancer care. Patient ratings of symptom severity and impact are important patient-reported outcomes (PROs) in cancer clinical trials and comprise a subset of a larger domain of PROs generally referred to as health-related quality of life (HRQOL). Symptoms rarely occur in isolation; rather, there is now ample evidence that symptoms frequently occur in clusters. The impact of these multiple symptoms upon the patient can be described as "symptom burden," a concept that encompasses both the severity of the symptoms and the patient's perception of the impact of the symptoms. The distress caused by symptoms is a subject of much investigation, and several validated measures of the severity and impact of multiple symptoms are now available. Symptom measures are generally brief, thereby reducing respondent burden, and can be administered repeatedly during a trial to give a relatively fine-grained picture of the patient's status across time. In many instances, information on trial-related changes in symptom burden, or comparison of symptom burden between arms in a clinical trial, may provide sufficient self-report data for clinical trial consumers (patients, clinicians, and regulators) to make treatment choices or to evaluate new therapies, without measuring other HRQOL domains.

Abstract
PURPOSE/OBJECTIVES To provide a comprehensive review of the literature and existing evidence-based findings on delirium in older adults with cancer. DATA SOURCES Published articles, guidelines, and textbooks. DATA SYNTHESIS Although delirium generally is recognized as a common geriatric syndrome, a paucity of empirical evidence exists to guide early recognition and treatment of this sequelae of cancer and its treatment in older adults. Delirium probably is more prevalent than citations note because the phenomenon is under-recognized in clinical practice across varied settings of cancer care. CONCLUSIONS Extensive research is needed to formulate clinical guidelines to manage delirium. A focus on delirium in acute care and at the end of life precludes identification of this symptom in ambulatory care, where most cancer therapies are used. Particular emphasis should address the early recognition of prodromal signs of delirium to reduce symptom severity. IMPLICATIONS FOR NURSING Ongoing assessment opportunities and close proximity to patients' treatment experiences foster oncology nurses' mastery of this common exemplar of altered cognition in older adults with cancer. Increasing awareness of and knowledge delineating characteristics of delirium in older patients with cancer can promote early recognition, optimum treatment, and minimization of untoward consequences associated with the historically ignored example of symptom distress.

Fatigue and depression in cancer patients undergoing chemotherapy: an emotion approach. J Pain Symptom Manage 2006; 32:311-21. [PMID: 17000348 DOI: 10.1016/j.jpainsymman.2006.05.007] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2005] [Revised: 03/15/2006] [Accepted: 05/11/2006] [Indexed: 11/17/2022]
Abstract
Fatigue and depressive symptoms are common in cancer patients, but the nature of the relationship between the two remains unclear. We examined the degree to which two dimensions of emotion assessed as psychological factors (i.e., arousal and valence) predicted changes in fatigue and depressive symptoms over four cycles of chemotherapy in cancer patients who participated in a randomized clinical trial. Among 549 patients enrolled in the study, 525 provided data from a minimum of two treatments and were included in the multilevel modeling analyses. Multilevel models were used to identify significant predictors of initial levels and changes of fatigue and depressive symptoms and to determine the relationship between fatigue and depressive symptoms independent of other predictors proposed in this study. Multiple factors, including age, gender, and cancer site, predicted the initial levels. More importantly, the two dimensions of psychological factors significantly predicted changes in fatigue and depressive symptoms, in similar patterns but to different degrees. Specifically, changes in fatigue depended more on the valence dimension, whereas changes in depressive symptoms depended on both the valence and arousal dimensions. Theoretical and practical implications of the current findings are discussed and suggestions for interventions to alleviate fatigue and depressive symptoms in cancer patients are proposed.

Abstract
PURPOSE Cancer-related fatigue contributes to negative outcomes relative to psychosocial and symptom distress, functional status, and quality of life, and yet it is often underdiagnosed and management is frequently suboptimal. DESIGN Systematic database searches were conducted, and primary research reports and meta-analyses of quantitative studies of interventions for fatigue published in English were identified and critically examined. RESULTS This paper reviews the etiology and evaluation of cancer-related fatigue and analyzes current empirical evidence supporting pharmacologic and nonpharmacologic techniques for its management. DISCUSSION A variety of pharmacologic and nonpharmacologic techniques to manage cancer-related fatigue have been studied, although most of the evidence is from single-arm pilot studies with small sample sizes, rather than from adequately powered, multicenter, randomized controlled trials. Continued research in ethnically and racially diverse samples is needed to identify the interventions that are most effective in specific cancer subpopulations and to develop and test interventions for fatigue at each phase in the illness trajectory.

Abstract
We validated the Taiwanese version of the Brief Fatigue Inventory (BFI-T) in a sample of 439 Taiwanese patients with multiple cancer diagnoses. Internal consistency was indicated by Cronbach alphas of 0.96 for fatigue-related severity and 0.95 for interference. Test-retest reliability was 0.89 for fatigue severity and 0.91 for interference. Factor analysis revealed a one-factor structure. Convergent validity was examined by correlating the BFI-T worst fatigue and fatigue severity composite scores with POMS vigor and fatigue subscales scores. Known-group validity was established by comparing BFI-T worst fatigue and severity composite scores between patients with low functional status and high functional status and between inpatients and outpatients. The BFI-T's sensitivity was examined by comparing BFI-T severity and interference composite scores before, during, and after chemotherapy treatment in a subsample of 20 breast cancer patients. The BFI-T is reliable, valid, and sensitive for measuring cancer-related fatigue severity and interference among Taiwanese cancer patients.

Risk of the "androgen deprivation syndrome" in men receiving androgen deprivation for prostate cancer. ACTA ACUST UNITED AC 2006; 166:465-71.

Abstract
BACKGROUND Androgen deprivation therapy for prostate cancer has been associated with a spectrum of adverse effects, such as depression, memory difficulties, and fatigue, termed the androgen deprivation syndrome. Primary care physicians providing follow-up care for men with prostate cancer will be faced with managing these effects. We therefore sought to estimate the incidence of these effects and, by using a control group, ascertain whether these effects were related to androgen deprivation itself. METHODS We assessed the risk of physician diagnoses of depression, cognitive impairment, or constitutional symptoms in Medicare data following androgen deprivation using a sample of 50 613 men with incident prostate cancer and 50 476 men without cancer, from 1992 through 1997, in the linked Surveillance, Epidemiology, and End Results-Medicare database. Cox proportional hazards regression was used to adjust for confounding variables. RESULTS Of men surviving at least 5 years after diagnosis, 31.3% of those receiving androgen deprivation developed at least 1 depressive, cognitive, or constitutional diagnosis compared with 23.7% in those who did not (P<.001). After adjustment for variables such as comorbidity, tumor characteristics, and age, the risks associated with androgen deprivation were substantially reduced or abolished: relative risk (RR) for depression diagnosis, 1.08 (95% confidence interval [CI], 1.02-1.15); RR for cognitive impairment, 0.99 (95% CI, 0.94-1.04); and RR for constitutional symptoms, 1.17 (95% CI, 1.13-1.22). CONCLUSION Depressive, cognitive, and constitutional disorders occur more commonly in patients receiving androgen deprivation, but this appears to be primarily because patients receiving androgen deprivation are older and have more comorbid conditions and more advanced cancers.

Abstract
Delirium is a common problem and cause of distress among patients with palliative care needs. The focus to date has been on managing the patient with agitated, hyperactive delirium, as these patients are very noticeable within the palliative care setting. This study in two parts shows that palliative care patients with agitated delirium are a minority of the total proportion of those with delirium. Part I: 100 acute admissions to a specialist palliative care unit were assessed and while 29% were found to have delirium, 86% of these had the hypoactive subtype of delirium. We also demonstrated a positive correlation between high ratings on a depression screening tool and delirium severity ratings. Part II: 8 specialist palliative care units took part in a point prevalence study of delirium over a 48-hour period. One hundred and nine patients were assessed and while 29.4% of these inpatients had delirium, 78% of them had the hypoactive subtype. Patients with hypoactive delirium may be much less noticeable or may be misdiagnosed as having depression or fatigue and the results of this study would advocate the routine use of delirium screening tools in all palliative care settings.

Abstract
BACKGROUND Estimates of the prevalence of cancer-related fatigue (CRF) are wide, and data suggest that fatigue is more prevalent among cancer patients than among the general population. However, most studies examining the prevalence of CRF have been hospital-based or clinic-based studies, which often are subject to bias. METHODS Point prevalence and prevalence odds ratios of fatigue were estimated using data from a large, population-based cohort that was screened for fatigue and linked with national registry-based data about cancer. Prevalence odds ratios and 95% confidence intervals were calculated using logistic regression with general estimating equations. RESULTS Approximately 23% of cancer registrants reported abnormal fatigue in the previous 6 months, 19% reported abnormal fatigue that lasted for at least 1 month, 14% reported abnormal fatigue that lasted at least 6 months, and 11% reported abnormal fatigue that lasted at least 6 months and caused significant functional impairment. Individuals who were listed in the cancer registry within the last 5 years were more likely to report experiencing fatigue than individuals who were not listed. There was an elevated prevalence of fatigue among those who were registered with carcinomas of the lung, uterine cervix, colon-rectum, ovaries, and prostate. Both women and men who were listed recently in the cancer registry were more likely to experience any level of fatigue than the comparison group. However, a greater proportion of women experienced fatigue relative to men. CONCLUSIONS A greater proportion of individuals who were listed in a national cancer registry reported experiencing fatigue compared with individuals in the general population.

Abstract
OBJECTIVES This study assessed the rates and course of depressive symptomatology and neurocognitive deficits in hepatitis C virus (HCV) patients undergoing interferon treatment, and explored possible predictors of depression and neurocognitive deficits. DESIGN In order to obtain objective assessments of depression, and to evaluate cognitive impairment, a 72-week prospective study, comprising 48 weeks of treatment and 24 weeks of post-treatment follow-up was utilized. METHODS A total of 50 HCV patients were assessed at baseline, and 14 times during pegylated interferon plus ribavirin treatment. Patients were also assessed on four timepoints after the termination of treatment. All patients have previously been treated for hepatitis C infection with interferon and were judged to be treatment resistant in these treatments. Depression was assessed using the Center for Epidemiological Studies Depression (CES-D) questionnaire, and patients were interviewed regarding problems with memory, attention and concentration. RESULTS Eighty-two per cent of interferon-treated patients developed severe enough depressive symptoms to meet the CES-D criteria for possible major depressive disorder (MDD). Possible MDD onset was most frequent by the first week of treatment, and almost all possible MDD cases were observed by week 8. More severe depressive symptoms at baseline were associated with higher depressive symptoms during interferon treatment. Thirty per cent of patients complained about cognitive problems. In half of these patients cognitive impairments were still reported after the termination of treatment. There was no association between depression during interferon treatment and subjective cognitive complaints. CONCLUSIONS The findings suggest that depression and cognitive impairments are frequent and persistent side-effects of interferon treatment in treatment-resistant patients.

Abstract
Purpose To estimate the prevalence of fatigue, identify the factors associated with fatigue, and to explore the relationship between fatigue and quality of life (QOL) in long-term survivors of childhood acute lymphoblastic leukemia (ALL). Methods One hundred sixty-one ALL survivors diagnosed at Childrens Hospital Los Angeles (Los Angeles, CA) before age 18 years and between January 1, 1975 and December 31, 1995, participated in a structured telephone interview. Participants were aged 18 to 41 years and off treatment for an average of 14 years. Four measures of fatigue, including the Revised–Piper Fatigue Scale, were used to assess fatigue; depression was assessed using the Center for Epidemiological Studies Depression Scale. Multivariate logistic regression models were developed to identify factors associated with fatigue and depression. Results Prevalence of fatigue (30%) fell within the general population normal limits. Fatigue and depression were highly correlated (Pearson r = 0.75). Fatigue was associated with marriage (OR = 0.11; 95% CI, 0.02 to 0.50), having children (OR = 5.80; 95% CI, 1.30 to 25.82), sleep disturbances (OR = 6.15; 95% CI, 2.33 to 16.22), pain (OR = 5.56; 95% CI, 2.13 to 14.48), obesity (OR = 3.80; 95% CI, 1.41 to 10.26), cognitive impairment (OR = 2.56; 95% CI, 1.02 to 6.38), and exercise-induced symptoms (OR = 2.98; 95% CI, 1.11 to 8.02). Four factors associated with fatigue were also associated with depression: sleep disturbances, pain, obesity, and cognitive impairment. Fatigue was inversely related to QOL. Conclusion Some survivors of childhood ALL experience fatigue many years after treatment. Fatigued survivors represent a high-risk subgroup as they report more depression and poorer QOL than nonfatigued survivors and their peers.
